Technical Field

The invention relates to the field of balance car control, in particular to a balance car rod and a balance car.

Background

The operation principle of the electric balance vehicle, also called a somatosensory vehicle and a thinking vehicle, is mainly based on a basic principle called dynamic stability, a gyroscope and an acceleration sensor in the vehicle body are utilized to detect the change of the posture of the vehicle body, and a servo control system is utilized to accurately drive a motor to carry out corresponding adjustment so as to keep the balance of the system.

The conventional electric balance car generally has two types, one type is that a car body is provided with an operating lever, and a user stands on a pedal platform of the electric balance car to operate the operating lever so as to move forward, backward and stop, and the control is also called manual control. The other is that the vehicle body is composed of two parts, the left part and the right part rotate mutually through a rotating mechanism, and therefore foot control is achieved.

The existing balance car rod with the car rod is fixed and unchangeable in length, and people with a specific height can obtain better driving experience, but the balance car rod is not suitable for ultra-high people or ultra-low people such as children.

The cap 40 is fixed to the opening of the hollow tube 10 by a screw. The cap sleeve 40 can facilitate the disassembly and assembly of the movable shaft 30 and the spring 20, and can be matched with the movable shaft 30 to form a positioning structure of the spring 20.

The top and bottom surfaces of the interior of the cap 40 are both flat surfaces 70; accordingly, the upper and lower surfaces of the movable shaft 30 are also flat surfaces 70, which cooperate with the top and bottom surfaces of the interior of the cap 40 to form a limit structure for limiting the rotation of the movable shaft 30. The movable shaft 30 is limited by the inner diameter shape of the cap sleeve 40, so that the rotating shaft 32 is prevented from rotating, a limiting structure does not need to be arranged in the hollow pipe body 10, and the production and manufacturing cost is reduced.

The length of the axle 50 is greater than the caliber of the cap 40. Thus, when the rotating shaft 32 is perpendicular to the cap 40, namely, when the wheel 60 is folded, the wheel is clamped at the opening of the cap 40 by the stress of the spring 20, so that automatic positioning is realized.

A groove 31 is formed at one end of the movable shaft 30 fixed with the wheel shaft 50; a rotating shaft 32 is arranged between the two inner walls of the groove 31; correspondingly, the axle 50 is embedded in the groove 31; the axle 50 is provided with a through hole for sleeving the rotating shaft 32; when the axle 50 rotates to be parallel to the movable shaft 30, the rotating shaft 32 can be embedded into the hollow tube 10 together with the movable shaft 30; when the rotating shaft 32 rotates to be perpendicular to the movable shaft 30, the rotating shaft 32 abuts against the opening of the cap 40.

After the movable shaft 30 is sleeved with the spring 20, the tail end of the spring 20 can abut against the disc 33, and the movable shaft 30 is dragged to move towards the inside of the hollow tube 10 by the resilience force of the spring 20.

Alternatively, the cap 40 is not required in the present invention, and it is also possible to form the positioning structure of the spring 20 and the movable shaft 30 directly inside the hollow tubular body 10. Thus, the structure is more compact with fewer parts. Specifically, the hollow tube 10 has a non-circular structure, and may have an oval shape, a rectangular shape, or the like, and of course, the top surface and the bottom surface of the hollow tube may be provided as the plane 70; correspondingly, the upper surface and the lower surface of the movable shaft 30 are also planes 70, and are matched with the top surface and the bottom surface inside the hollow pipe body 10 to form a limiting structure for limiting the rotation of the movable shaft 30; then a concave edge is provided at the opening of the hollow tube 10 for positioning the spring 20.
