Description

Technical Field

[0001] This utility model relates to the field of motorcycle shock absorption technology, specifically to an electrically adjustable motorcycle shock absorber. Background Technology

[0002] Motorcycle shock absorbers are key components of the motorcycle suspension system. Their main function is to buffer the impact force transmitted to the frame due to uneven road surfaces and dampen the resulting vibrations to ensure a smooth and comfortable ride.

[0003] Currently, some motorcycles come with fixed-damping original shock absorbers. These shock absorbers often perform poorly when facing complex and varied riding conditions. For example, a stiffer damping is needed on smooth roads to ensure vehicle stability and handling, while a softer damping is needed on bumpy unpaved roads or off-road terrain to effectively absorb impacts and improve comfort. A fixed damping setting cannot satisfy both of these conflicting needs; therefore, there is a need for a motorcycle shock absorber with electrically adjustable damping. Utility Model Content

[0004] The purpose of this invention is to provide an electrically adjustable shock absorber for motorcycles, so as to at least partially solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a damping shock absorber body, with a base shell connected to the bottom of the damping shock absorber body via a threaded connection. A side shell is fixedly connected to one side of the base shell, and a linear motor is fixedly installed inside the side shell. A push rod capable of linear movement is installed at the output end of the linear motor. A piston that slides along the inner wall of the side shell is fixedly installed at the inner end of the push rod. A controller for controlling the linear motor is fixedly installed on the outer wall of the side shell.

[0006] Preferably, the damping shock absorber body includes a cylinder threaded on the connecting end of the base shell, and a piston rod slidably disposed inside the cylinder and extending outward at one end.

[0007] Preferably, the outer wall of the base shell is provided with a threaded hole, and a matching screw is threaded into the threaded hole. The inside of the base shell is provided with a liquid filling hole that communicates with the threaded hole and the cylinder.

[0008] Preferably, the inner wall of the base shell is provided with a first threaded mounting port, and the cylinder connecting end is provided with a thread for threaded connection in the first threaded mounting port.

[0009] Preferably, the outer wall of the side shell is provided with a second threaded mounting port, and the controller connection end is provided with a thread for threaded connection to the second threaded mounting port.

[0010] Preferably, the piston slides in close contact with the inner wall of the side shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, this utility model uses a linear motor to make the push rod push the connected piston to move linearly. When the piston moves towards the inner base shell, it increases the pressure of the liquid inside the base shell, which in turn increases the pressure of the liquid inside the interconnected cylinder. When the piston moves outward, it can reduce the pressure of the liquid inside the cylinder, thereby changing the damping stiffness inside the damping shock absorber body. It is suitable for use on different roads. A forward and backward control switch of the controller is added to the motorcycle handlebars, and the electric adjustment method is more convenient.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3This utility model provides a technical solution: an electric adjustable shock absorber for motorcycles, including a damping shock absorber body 1, a base shell 2 that is connected to each other by a thread at the bottom of the damping shock absorber body 1, a side shell 3 that is fixedly connected to each other on one side of the base shell 2, a linear motor 4 that is fixedly installed inside the side shell 3, a push rod 41 that can move linearly is provided at the output end of the linear motor 4, a piston 6 that slides on the inner wall of the side shell 3 is fixedly installed at the inner end of the push rod 41, and a controller 5 for controlling the linear motor 4 is fixedly installed on the outer wall of the side shell 3. The controller 5 controls the start of the linear motor 4, causing the push rod 41 to push the connected piston 6 to move. The piston 6 is connected to the base shell 2 through the side shell 3. When the piston 6 moves into the base shell 2, it increases the pressure of the liquid inside the base shell 2, which in turn increases the pressure of the liquid inside the interconnected cylinder 11. When the piston 6 moves outward, it can decrease the pressure of the liquid inside the cylinder 11, thereby changing the damping effect inside the damping shock absorber body 1. This method is suitable for use on different roads. A forward and backward control switch of the controller is added to the motorcycle handlebars, and the electric adjustment method is more convenient.

[0017] More preferably, the damping shock absorber body 1 includes a cylinder 11 threaded on the connecting end of the base shell 2, and a piston rod 12 slidably disposed inside the cylinder 11 and extending outward at one end; A liquid damper is formed by cylinder 11 and piston rod 12, and the damping strength of the damper body 1 is changed by adjusting the liquid pressure.

[0018] More preferably, the outer wall of the base shell 2 is provided with a threaded hole 23, and a matching screw 7 is threaded into the threaded hole 23. The inside of the base shell 2 is provided with a liquid filling hole 21 that communicates with the threaded hole 23 and the cylinder 11. The liquid required for damping can be added to the cylinder 11 and the base shell 2 through the liquid filling hole 21 inside the base shell 2. The liquid filling hole 21 is connected to the threaded hole 23 on the outer wall of the base shell 2. The liquid is filled and then aligned and sealed by the screw 7.

[0019] More preferably, the inner wall of the base shell 2 is provided with a first threaded mounting port 22, and the connecting end of the cylinder 11 is provided with a thread for threaded connection in the first threaded mounting port 22; The cylinder 11 is fixedly connected to the base shell 2 via a first threaded mounting port 22 inside the base shell 2.

[0021] In a further preferred embodiment, the piston 6 slides in close contact with the inner wall of the side shell 3.

[0022] One specific application of this embodiment is as follows: When the motorcycle is traveling on a bumpy road, the pressure reduction switch is turned on, and the linear motor 4 is started by the controller 5, so that the push rod 41 pushes the connected piston 6 to move and slide on the inner wall of the side shell 3. The side shell 3 is connected to the base shell 2, and the base shell 2 is connected to the cylinder 11. When the road is flat, the increase switch can be turned on, and the switch can be turned off when it is adjusted to a moderate position, so that the damping becomes stiffer to ensure the stability and handling of the vehicle.
