Children's electric car with their own hands. Self-made electromobile with own hands

It is rare to find a child who does not want to own a car. Especially this applies to electric cars, on which not only boys but also girls ride with enthusiasm. After all, in this case, the baby does not need to pedal, and the temptation to climb in the mud it will be less.

A simple electric car can be made with your own hands by fitting a screwdriver to a conventional pedal machine, which can be powered from a motorcycle battery. However, in this constructive scheme, there are many drawbacks, since brittle plastic has an unpleasant habit of falling apart from long exploitation.

In addition, the standard gear housing in this case simply does not have enough resources for any long-term operation, so that in any case you will have to upgrade and "fine-tune" the existing solutions.

Characteristics of the simplest car

As we already mentioned, the body is best taken from a conventional typewriter on pedal traction. If this is not possible, you can try to build something like that from plastic or even plywood. Doing an electric car with your own hands, you need to get a couple of engines from conventional screwdrivers. Reducers need to be taken from there, but for them it is necessary to make homemade steel cases. Output shafts are exposed on 201 bearings.

As in the prototype, the landing in this auto is lateral. The engines are powered by a conventional car battery type 6ST60. Small plastic wheels can be taken from garden trolleys or something like that. For the frame, a steel pipe with a diameter of 16 mm is taken.

Suspension

The suspension is best made in spring type. The braking system is electrical, by short-circuiting and through a resistor (for smooth braking).

You can put on the car horn, lights and mirrors. In a word, make a beautiful electric car with your own hands! Drawings must be done in advance, as this will allow better representation of the structure. All the general information we will give in this article, but no one will forbid you to connect your creative vein to the process.

At a top speed of 8 km / h this design has a power reserve of at least 30 km! The machine turns out to be a two-seater, without batteries weighs about 15 kg. Dimensions of auto - LxWxH (mm) - 880х560х570.

Electrical characteristics

When you begin to make an electric car with your own hands, this is the point to pay special attention to. The fact is that the reliability of the machine and the safety of your child depend on the characteristics of this equipment. Of course, the first thing to worry about is that all contacts are securely isolated.

Many believe that the braking system can be done by simply putting on the panel button "On / Off." From the screwdriver. Of course, in this case the control of the machine becomes as simple as possible. Just keep in mind that sudden braking can lead to very unpleasant consequences. So you need to do brakes through a resistor.

How to add speed?

Also keep in mind that the smooth start-up of a standard screwdriver (when used in a typewriter) quickly becomes unusable. The machine starts to start with jerks.

Select two-stage gas and brake buttons, adding resistance. Do not worry about the high battery losses: the first speed is used for a short time, so nothing terrible will happen.

We make the body of an "all-terrain vehicle"

Immediately determine that the body is best taken from the already finished car, as in the end your creation will look more aesthetically. Before you make an electric car with your own hands, we advise you to wander through the sites of online stores. Enterprising Chinese have long been selling anything, so finding the right body will not be difficult.

Points of attachment - in the place where the "donor" had pedals. To attach the rear part to the frame, it is necessary to make protrusions that will serve as additional ribs of rigidity. For the battery it is necessary to make a basket from the welded profile.

It is preferable to make one part of the body of the hinged, fixing it on suitable hinges in the dimensions. In this case, you will easily remove the battery for maintenance. If there is no suitable pipe, the frame can easily be made from old chairs with a steel frame. For the suspension, spare parts from quality baby carriages are ideal.

About the quality of materials ...

Doing an electric car with your own hands (the scheme of the simplest version we are discussing) from the parts of the stroller, you at the same time provide yourself with all the necessary spare parts, which are sold in a variety of specialized stores. Note that for this purpose it is necessary to select details from quality European wheelchairs, and not their Chinese and Polish imitations. The cheapest models use the cheapest plastic and very bad metal.

Such a design does not withstand even the use of its intended purpose, and even in the car breaks down and even more so.

Moreover, they already have ready-made fixtures, and therefore there is an opportunity to do without welding (it is not present at all). It's better to make a massive bumper, because it's easier to carry a typewriter for them. Doing suspension from the remains of the stroller, inspect the guide springs: if they are too stunted, it is better to strengthen them with steel strips.

We make the transmission

We have already agreed that as engines we will take those from the screwdriver. The reducer itself remains unchanged from the device, but the body must be turned out of steel on a lathe. The motors will transmit torque through a chain drive. The good thing is that there will not be any problems with this: at any bicycle shop you will find any asterisks in the required configurations.

It is difficult to speak about diameter. Take a smaller star - the speed will be higher, but also the wear of gearboxes, which are simply not designed for such loads, will also be much stronger. Needless to say, its large diameter will lead to unjustifiably high losses of electricity, since most of the time the mechanism will spin for nothing.

If there is such a desire, you can attach drums to the wheels for mechanical brakes. They can also be found in bicycle shops, but if desired and the availability of a lathe, they are easily made at home. In general, when assembling a quality self-made electric vehicle with your own hands, be sure to take care of access to the lathe equipment, since without it you simply can not make many details.

Bearings

But instead of regular bearings from the trolleys, you need to put 200 and 201 bearings with internal diameters of 10 and 12 mm. For installation, transitional enclosures are used, in the rear inner parts of which the threads for drums are made. Halves of the housings can be connected with a screed, fastening it with bolted connections.

Of course, if you have a normal lathe, then it's better to do without such tweaks, making all the details of solid steel blanks. This will be much stronger, and the reliability of such a design is not higher. And to do an electric car with their own hands for children should be done as reliable as possible!

Since we use electric brakes, the entire transmission is not very complicated. Parking brakes do not need. Keep in mind that you must use the car strictly under your supervision!

We make the chassis

The most complicated from the technical point of view is the knuckle-knuckle knot. It is better to take it from the "donor" pedal machine, putting the rubber stops of the wheel.

This will prevent unnecessarily sharp turns and tipping the car at high speed. Yes, this is also possible, since a children's electric car (it's not so difficult to make it by oneself) will in any case be obtained with a shifted center of gravity.

For limiters of rocking the body take ordinary rope traction, preventing the body from leaving the frame on the potholes and bumps. The front axle is attached to the swing arms. Since the weight of the machine is small, it is pointless to set any complicated transverse links. It is better to strengthen the springs of the suspension, which in this case easily withstand even two toddlers.

Instead of rocking levers, which are not so easy to find, you can apply two strips of stainless steel 1.5 mm thick, longitudinally fixed on the frame. However, it is worth remembering that you can not take a regular steel strip: it will have an excessively heavy load on its front parts, which will inevitably lead to deformation and destruction of the material.

To avoid such a phenomenon, the thickness of the front third of the bands should be increased by about 2/3, by welding a suitable steel angle bracket to it. In short, before you make an electric car with your own hands, pre-purchase all the necessary "scrap metal" in advance.

More about steering

The steering unit is made on the basis of the most primitive link structure. Having looked at the controls of any toy pedal machine, you will easily do something similar yourself. Steering tips are better to take ready, having bought them in an automobile shop.

Fasteners are similar to those used in the doors of cars. Rotary fists (as we mentioned) can be taken ready, but if necessary they are not so difficult to cut out a steel sheet 2 mm thick.

The levers of the steering represent one with them. The front part is bent in the form of a channel, welding to its front part the turned hollow axis. The pin can be easily turned from a standard "furniture" bolt. For the tie rods, a tube with a diameter of 8 mm is taken. Hinges can be found in a furniture store. Their strength is quite enough.

Make an imperial gift to your child by giving him an electric car. With your own hands it's easy to assemble, but the kid will experience the joy from it!
