Description

Technical Field

[0001] The present invention relates to the technical field of vehicle shock absorption, and particularly to an electric shock absorption mechanism. Background Art

[0002] A shock absorber is an important component for absorbing vibrations in vehicles such as automobiles, motorcycles, and bicycles. During operation, the spring in the spring shock absorber continuously contracts and expands, and it takes a certain amount of time for the natural vibration to converge. Therefore, an oil pressure shock absorber is also required to avoid affecting the driving performance. Such a design causes the shock absorption mechanism of the vehicle to occupy a large space. Especially when applied to motorcycles, the bulky shock absorption mechanism will affect the aesthetics of the motorcycle, and the disassembly and assembly difficulty is also higher, and the convergence effect is not satisfactory. Summary of the Invention

[0003] The purpose of the present invention is to provide an electric shock absorption mechanism, aiming to solve the problems of the existing shock absorption mechanism such as bulky structure and poor convergence effect.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] Provide an electric shock absorption mechanism, including a shock absorber, a swing arm, a vehicle frame, a motor, and a rotating shaft. One end of the shock absorber is connected to the swing arm, and the other end of the shock absorber is connected to the vehicle frame. The swing arm is rotatably connected to the vehicle frame through the rotating shaft. The motor is arranged on the swing arm, and the motor is connected to the rotating shaft.

[0006] Optionally, the motor includes a housing, a stator, and a rotor. The housing is arranged on the swing arm, the stator and the rotor are both arranged in the housing, and the rotor is connected to the rotating shaft.

[0007] Optionally, the rotor and the rotating shaft are connected by a spline.

[0008] Optionally, the electric shock absorption mechanism further includes a locking nut, and the rotating shaft is connected to the vehicle frame through the locking nut.

[0009] Optionally, the electric shock absorption mechanism further includes a control unit, and the control unit is electrically connected to the motor.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The electric shock absorption mechanism provided by the present invention is provided with a shock absorber, a motor and a rotating shaft in addition. The rotation of the rotating shaft can be controlled by the motor to achieve more active control of the shock absorber. Specifically, during the shock absorption process, when the shock absorber compresses, the swing arm will rotate. At this time, the motor works to drive the rotating shaft to rotate in the opposite direction, so as to reduce the convergence time of the shock absorber, improve the shock absorption effect of the entire shock absorption mechanism, and improve the driving performance of the vehicle. In addition, the electric shock absorption mechanism of the present invention can adjust the angle between the swing arm and the vehicle frame by controlling the rotation of the rotating shaft by the motor. The swing arm is connected to the wheel, so the height of the vehicle body can be adjusted in this way, which is more convenient to adjust and has stronger functionality.

Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0020] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0021] The following Figures 1 to 4 describes the electric shock-absorbing mechanism of the present invention.

[0022] As Figures 1 to 4 shown, the present invention provides an electric shock-absorbing mechanism, including a shock absorber 1, a swing arm 2, a vehicle frame 3, a motor 4 and a rotating shaft 5. One end of the shock absorber 1 is connected to the swing arm 2, and the other end of the shock absorber 1 is connected to the vehicle frame 3. The swing arm 2 is rotatably connected to the vehicle frame 3 through the rotating shaft 5. The motor 4 is arranged on the swing arm 2, and the motor 4 is connected to the rotating shaft 5.

[0023] For the electric shock-absorbing mechanism provided in this embodiment, in addition to being provided with the shock absorber 1, a motor 4 and a rotating shaft 5 are also provided. The rotation of the rotating shaft 5 can be controlled by the motor 4 to achieve more active control of the shock absorber 1.

[0024] Specifically, as Figure 3 shown, during the shock-absorbing process, when the shock absorber 1 compresses, the swing arm 2 will rotate. At this time, the motor 4 works to drive the rotating shaft 5 to rotate in the opposite direction. Similarly, when the shock absorber 1 extends, the swing arm 2 will rotate. At this time, the motor 4 works to drive the rotating shaft 5 to rotate in the opposite direction, thereby being able to reduce the convergence time of the shock absorber 1, improve the shock-absorbing effect of the entire shock-absorbing mechanism, and enhance the driving performance of the vehicle.

[0025] In addition, as Figure 4 shown, the electric shock-absorbing mechanism of this embodiment can adjust the angle between the swing arm 2 and the vehicle frame 3 by controlling the rotation of the rotating shaft 5 by the motor 4. The swing arm 2 is connected to the wheel. Therefore, in this way, the height of the vehicle body can be adjusted, which is more convenient to adjust and has stronger functionality.

[0026] In some embodiments, the motor 4 includes a housing 41, a stator 42, and a rotor 43. The housing 41 is provided on the swing arm 2, and both the stator 42 and the rotor 43 are provided in the housing 41. The rotor 43 is connected to the rotating shaft 5. After the motor 4 is powered on, the movement of the rotor 43 can be controlled, thereby driving the rotation of the rotating shaft 5, and further driving the relative rotation between the swing arm 2 and the vehicle frame 3, with a faster response.

[0027] In some embodiments, the rotor 43 and the rotating shaft 5 are connected by a spline, with a firm connection and no relative rotation, enabling the rotor 43 to better drive the rotation of the rotating shaft 5.

[0028] In some embodiments, the electric shock absorption mechanism further includes a locking nut 6. The rotating shaft 5 is connected to the vehicle frame 3 through the locking nut 6, which can fix the rotating shaft 5 and the vehicle frame 3, with better stability.

[0029] In some embodiments, the electric shock absorption mechanism further includes a control unit, which is electrically connected to the motor 4 and can better control the operation of the motor 4.

[0030] In some embodiments, the control unit is a single-chip microcomputer, which can better control the operation of the motor 4.

[0031] The above are only embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
