Description

A folding device for a combined balance car

technical field

The invention relates to a balance car, in particular to an automatically foldable combined balance car whose front end is combined and connected to a multi-purpose box.

Background technique

A self-balancing car is a highly automated driving tool. Since it officially entered China in August 2006, it has been familiar to the general public. Various shapes of self-balancing cars have been applied. The main operating principle of the self-balancing car is the dynamic balance system, that is, The gyroscope and angular acceleration sensor are used to control the dynamic balance of the human body. When the center of gravity leans forward, it will move forward, and when it is backward, it will retreat. There are mainly two types of self-balancing vehicles on the market, one-wheel and two-wheel, which are green and environmentally friendly. Small and flexible automation tool; but currently it can only be used for leisure and entertainment, and cannot be driven on the road. Beijing has also issued the relevant provisions of the "Measures for the Implementation of the "Road Traffic Safety Law" in Beijing." Unnecessary harm to self and others. It is reported that at the end of last month, the traffic control department has issued a notice to fine the self-balancing car sliding on the municipal public road 10 yuan, and will order the violator to make corrections immediately and not continue to use this kind of sliding tool.

This is why, the same two-wheeled vehicles, such as bicycles, two-wheeled electric vehicles, etc., can be driven on the road. This is because of safety issues. The wheels of bicycles and two-wheeled electric vehicles are set at the front and rear, which is beneficial Dynamic brakes offset the inertia generated by objects when they are moving; however, the two-wheeled self-balancing vehicle is set on the left and right. From the side view, it is the same as the unicycle and receives force on the ground, which is conducive to the change of the center of gravity of the human body to achieve self-balancing on the self-balancing vehicle. The system senses the center of gravity of the human body; the braking of the self-balancing car uses the center of gravity to stop backwards. The self-balancing car is safe when the road surface is good, the driving is slow and ready, but it is very dangerous when it is fast or sudden. Because the object will naturally generate forward inertia when it is moving, and the inertia will make the center of gravity of the person move forward naturally, and the forward center of gravity will start the advancement of the balance car again, that is, the self-balancing system and the inertia have a chain conflict. Unable to brake in time, brake failure; the most feared thing for moving vehicles is brake failure, which is also the main reason why self-balancing vehicles cannot be driven on the road and cannot be widely used in society; how to make self-balancing vehicles safer and more convenient to carry transportation.

Contents of the invention

The technical problem to be solved by the present invention is to provide a self-folding combined balancing vehicle whose front end is combined and connected to a multi-purpose box.

A folding device for a combined balance car, including a connecting mounting frame, a power-assisted connecting piece and a two-wheeled balancing car, characterized in that the left and right shafts on the rear side of the connecting mounting frame are connected with power folding bars, and the power folding bars on the left and right Linkage gears are respectively arranged on the connecting shafts of the strips, and two identical linkage gears are arranged between the left and right linkage gears, and the four linkage gears are identical and mutually transmitted, and one of the linkage gears is A folding power is provided, and the folding power includes a motor and a reducer;

The rear ends of the power folding bars on the left and right are respectively connected with folding connecting bars, and the two-wheel balance car is provided with power-assisted connecting parts, and the left and right front ends of the power-assisted connecting parts are respectively provided with folding shaft connecting parts. The rear ends of the connecting bars are pivotally connected to the left and right folding pivot joints respectively.

A multi-purpose box is arranged on the connection mounting frame, and a telescopic handle is arranged on the multi-purpose box; a plurality of anti-collision sensors are arranged on the multi-purpose box and the two-wheel balance car, and the When the anti-collision sensor senses an obstacle, the two-wheeled self-balancing vehicle will slow down, and as the distance from the obstacle continues to approach, the speed of the two-wheeled self-balancing vehicle will gradually return to zero.

When the power of the two-wheel balancing car is turned off, the folding device automatically folds; when the power of the two-wheel balancing car is turned on, the folding device automatically extends.

Once, it was reported on TV that nurses in a hospital used a two-wheeled balance car. Using a two-wheeled balance car for transportation seems to be the development direction of a modern hospital, but the inspiration told me: if the two-wheeled balance car is combined with a medical trolley, This will be safer, more convenient and more comfortable;

In order to test its feasibility and effect, I bought a two-wheel balance car online for 500 yuan, and bought a suitcase for 150 yuan. I used two spring steel strips 4 cm wide, 0.8 mm thick, and 38 cm long. The belt connects the balance car to the bottom of the suitcase at the front and rear. The distance between the two-wheel balance car at the rear end and the suitcase at the front is about 15 cm. Step on the balance car and try it out: you can drive stably with great flexibility Well, it can turn 360 degrees on the spot, and the effect is surprisingly good. After 30 minutes of practice at home, I went out on the road. Because I held the trolley of the suitcase with one hand, the uphill and downhill were very stable over low obstacles; I don’t know how many times I fell when I was learning a bicycle. I have also used the electric skateboard I made for nearly half a year. Safe; without the pull rod of the front suitcase as a support point, it is very difficult and very dangerous to drive a two-wheeled self-balancing car; this shows that the combination of a two-wheeled self-balancing car and a moving object with a universal wheel at the front is reasonably feasible.

The setting of the folding device can minimize the space when folding, but the length is larger when stretching; if the diameter of the linkage gear on the left and right power folding bars is large enough to be directly driven, there is no need to add two or four people in the middle The transmission gear; the setting of the limit bar can be relatively fixed on the fall of the two-wheeled self-balancing car when it is folded; the anti-collision sensor can be set on the front, left, right side of the multi-purpose box and the rear side of the two-wheeled self-balancing car, and the anti-collision sensor The sensor is connected to the central processing unit in the two-wheel balance car. If it senses a person or object, it will automatically slow down to a lower speed. If it encounters or is about to encounter it, the speed of the two-wheel balance car will automatically return to zero. stop; the traditional balance car cannot be decelerated or returned to zero by external force, which will break the law of the automatic balance system and cause a fall; The inertia from external force deceleration and stop can be offset by the contact between the arm and the telescopic handle; the force point of the front buffer universal wheel does not directly act on the two-wheel balance car, but through the power-assisted connector and the two-wheel balance car. Active connection, so it does not affect the drive and flexibility of the center of gravity of the two-wheeled self-balancing vehicle; the power-assisted device can be magnetic or spring, etc., due to the role of the power-assisted device, the pedal rotation of the two-wheeled self-balancing car has relative resistance, so standing on it will be easier easy;

The power key of the two-wheel balance car can be installed on the two-wheel balance car or on the multi-purpose box. When it is opened, the folding device will automatically stretch and can be used; when it is closed, the folding device will automatically fold and can be carried or pulled; it is suitable for work, Going to school, going out to work, traveling, etc., you can pick it up to go to high-speed rail, subway and other means of transportation, and start the power to drive. It is safe, flexible and convenient. The multi-purpose box can store the required items.

The advantages of the present invention are: for the two-wheeled self-balancing vehicle: it does not affect its advantages, and increases a lot of safety; and for the multi-purpose box at the front end: it increases a lot of practicability and selectivity; the combination is scientific and reasonable, and it is easy to drive Flexible and safe; simple in structure, it can serve the society more widely.
