[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, the shock-absorbing device of an embodiment of the present invention includes: a first sliding part 1, the first sliding part 1 having a first sliding cavity 11 and an opening 12 communicating with the first sliding cavity 11; a second sliding part 2, the second sliding part 2 having a second sliding cavity 21, the second sliding part 2 being inserted into the first sliding cavity 11 through the opening 12, so that the first sliding part 1 and the second sliding part 2 are slidably disposed relative to each other; a driven member 3, the driven member 3 being movably disposed on the first sliding part 1 relative to the first sliding part 1, one end of the driven member 3 being located in the first sliding cavity 11; wherein, the outer wall of the second sliding part 2 is sealed to the inner wall of the first sliding part 1, and the second sliding part 2 is provided with a communicating hole 22 for communicating the second sliding cavity 21 and the first sliding cavity 11; the first sliding cavity 11 and the second sliding cavity 21 are filled with damping fluid, so that the driven member 3 moves relative to the first sliding part 1 when the pressure in the first sliding cavity 11 increases.

[0024] The main body of the shock absorption device in this embodiment of the invention is composed of a first sliding part 1 and a second sliding part 2. The first sliding part 1 has a hollow structure inside, forming a first sliding cavity 11. One end of the first sliding part 1 is open, forming an opening 12 connected to the first sliding cavity 11. The second sliding part 2 also has a hollow structure inside, forming a second sliding cavity 21. The second sliding part 2 is inserted into the first sliding cavity 11 of the first sliding part 1 from the opening 12 of the first sliding part 1. The second sliding part 2 inserted into the first sliding cavity 11 and the first sliding part 1 can slide relative to each other.

[0025] The first sliding part 1 is provided with a driven part 3, the driven part 3 is out of the side wall of the first sliding cavity 11 of the first sliding part 1, one end of the driven part 3 is out of the first sliding part 1, and the other end is in the first sliding cavity 11 and can move in and out in the out direction. The sliding connection between the first sliding part 1 and the second sliding part 2 is a sealed structure, one end of the second sliding part 2 inserted into the first sliding part 1 is provided with a communication hole 22, the communication hole 22 communicates the first sliding cavity 11 and the second sliding cavity 21, and the first sliding cavity 11 and the second sliding cavity 21 are filled with damping liquid. The damping liquid is an oil-like liquid with viscous resistance. When the second sliding part 2 is forced to impact upwardly in the first sliding cavity 11 of the first sliding part 1 instantaneously, the damping liquid in the first sliding cavity 11 can buffer the impact force of the second sliding part 2, so that the kinetic energy is attenuated, the damping device returns to a stable state, and the damping liquid can flow between the first sliding cavity 11 and the second sliding cavity 21 through the communication hole 22.

[0026] When the automobile runs on the bumpy road and vibrates, the damping device of the automobile performs buffering movement, the second sliding part 2 in the damping device is forced to slide upwardly relative to the first sliding part 1, extrudes the first sliding cavity 11 in the first sliding part 1, the space of the first sliding cavity 11 is reduced, the pressure is increased, the damping liquid in the first sliding cavity 11 is extruded and flows from the first sliding cavity 11 into the second sliding cavity 21 through the communication hole 22, the damping liquid in the first sliding cavity 11 starts to flow, and the flowing damping liquid pushes the driven part 3 installed in the first sliding cavity 11 to move outwardly, and generates kinetic energy to the outside.

[0027] When the external force acting on the second sliding part 2 disappears, the pressure in the first sliding cavity 11 is released, the second sliding part 2 is pushed to slide downwardly relative to the first sliding part 1, the damping liquid extruded into the second sliding cavity 21 gradually reduces the pressure in the first sliding cavity 11 and flows back into the first sliding cavity 11 through the communication hole 22, the damping liquid in the first sliding cavity 11 starts to flow, and the flowing damping liquid pushes the driven part 3 installed in the first sliding cavity 11 to move outwardly, and generates kinetic energy to the outside.

[0028] In this way, in the operation of the damping device of the automobile, the driven part 3 installed therein can be continuously pushed to continuously output kinetic energy to the outside. At this time, the power generation mechanism is arranged outside the damping device, so that the kinetic energy can be converted into electric energy for use by the automobile power system, solving the problem of energy waste that the existing shock absorber is difficult to utilize the offset energy.

[0029] In the damping device of the embodiment, Figure 1 , Figure 2As shown in the figure, the driven component 3 comprises a pressing component 31 and a rod component 32 connected with each other, the outer circumferential surface of the pressing component 31 protrudes from the outer circumferential surface of the rod component 32; the pressing component 31 is located in the first sliding cavity 11, and the rod component 32 is arranged on the first sliding component 1.

[0030] The driven component 3 is arranged as the pressing component 31 and the rod component 32, the outer circumferential surface of the pressing component 31 protrudes from the outer circumferential surface of the rod component 32; the pressing component 31 is located in the first sliding cavity 11, and the rod component 32 is arranged on the first sliding component 1, so that the position of the driven component 3 can be limited and cannot be separated from the first sliding cavity 11.

[0031] As shown in the figure, Figure 1 In this embodiment, the damping device further comprises: one end of the elastic component 4 is connected with the first sliding component 1, and the other end of the elastic component 4 is connected with the driven component 3, so that when the pressure in the first sliding cavity 11 decreases, the driven component 3 returns to the original position under the elastic action of the elastic component 4.

[0032] In order to make the driven component 3 in the damping device continue to move, the elastic component 4 is arranged on the damping device, one end of the elastic component 4 is connected with the first sliding component 1, and the other end of the elastic component 4 is connected with the driven component 3, when the pressure in the first sliding cavity 11 decreases, the driven component 3 returns to the original position under the elastic action of the elastic component 4, so that the damping liquid in the first sliding cavity 11 pushes the driven component 3 to move again.

[0033] In the damping device of this embodiment, as shown in the figure, Figure 1 The driven component 3 is a permanent magnet, and the damping device further comprises: a coil winding 5, at least part of the permanent magnet is located in the cavity of the coil winding 5, so as to generate electric energy when the permanent magnet moves relative to the coil winding 5.

[0034] In order to convert the kinetic energy of the driven component 3 into electric energy to supply the electric power system of the automobile, the driven component 3 is arranged as a permanent magnet, and the damping device is provided with a coil winding 5, when the driven component 3 is pushed by the damping liquid to move out of the first sliding cavity 11, it can move relative to the coil winding to generate electric energy.

[0035] As shown in the figure, Figure 1 In the damping device of this embodiment, the coil winding 5 is fixed on the outer wall of the first sliding component 1.

[0036] The coil winding 5 is fixed on the outer wall of the first sliding component 1, which can make full use of the kinetic energy generated by the driven component 3 for external use without affecting the damping effect inside the damping device.

[0037] As shown in the figure, Figure 1As shown in the drawings, in the damping device of the present embodiment, the permanent magnets and the coil windings 5 are both multiple, and the multiple permanent magnets and the multiple coil windings 5 are arranged one-to-one correspondingly; the multiple coil windings 5 are arranged at intervals around the first sliding part 1.

[0038] In order to make the most of the kinetic energy generated by the flow of damping liquid in the first sliding cavity 11, the permanent magnets and the coil windings 5 are both multiple, and the multiple permanent magnets and the multiple coil windings 5 are arranged one-to-one correspondingly; the multiple coil windings 5 are arranged at intervals around the first sliding part 1, which can make full use of the different directions of the pushing force generated by the flow of damping liquid in different parts of the first sliding cavity 11, so that the energy utilization is more sufficient.

[0039] As shown in the drawings, in the damping device of the present embodiment, the center lines of the permanent magnets in the moving direction of the permanent magnets are located on the same plane. Figure 1

[0040] By locating the center lines of the permanent magnets in the moving direction of the permanent magnets on the same plane, the structure of the damping device as a whole is symmetrical, which can make the force uniform when the damping device is impacted by external force, thereby ensuring the stability of the structure.

[0041] As shown in the drawings, in the damping device of the present embodiment, the end of the second sliding part 2 located in the first sliding cavity 11 has a pushing part 23, so as to push the driven part 3 to move when the second sliding part 2 extends into the inside of the first sliding cavity 11. Figure 1

[0042] In the present embodiment, the pushing part 23 is arranged at the end of the second sliding part 2 located in the first sliding cavity 11, and when the second sliding part 2 extends into the inside of the first sliding cavity 11, the pushing part 23 can directly contact the driven part 3, thereby pushing the driven part 3 to move outward. When the damping device of the automobile is subjected to severe vibration, the external force acting on the second sliding part 2 increases, at this time, the stroke of the second sliding part 2 in the first sliding cavity 11 becomes longer, and the second sliding part 2 continuously slides towards the inside of the first sliding cavity 11 under the pushing of the external force, when the second sliding part 2 slides to the position where the driven part 3 is located, at this time, the pushing part 23 is arranged at the position where the second sliding part 2 contacts the driven part 3, and directly pushes the driven part 3 to move, which is a more effective pushing mode, and further utilizes the kinetic energy generated by the vibration of the automobile.

[0043] As shown in the drawings, in the damping device of the present embodiment, the outer wall surface of the pushing part 23 is in a conical structure, and the circumference of the cross section of the pushing part 23 perpendicular to the sliding direction of the second sliding part 2 gradually decreases along the extending direction of the second sliding part 2; the communication hole 22 is arranged on the pushing part 23. Figure 1

[0044] ​​​In this embodiment, the outer wall surface of the pushing part 23 is configured as a tapered structure, and the perimeter of the cross-section of the pushing part 23 perpendicular to the sliding direction of the second sliding part 2 gradually decreases along the insertion direction of the second sliding part 2; a connecting hole 22 is provided on the pushing part 23. This structure, as... Figure 1 As shown, when the second sliding part 2 slides upward within the first sliding cavity 11, the conical pushing part facilitates the movement of the second sliding part within the first sliding part 1 filled with damping fluid, allowing the damping fluid to flow more smoothly out of the first sliding cavity 11 through the connecting hole 22 on the pushing part 23, thus enhancing the pushing effect of the damping fluid. Furthermore, as the second sliding part 2 moves further into the first sliding cavity 11, the pushing part 23 contacts the driven component 3. The conical structure allows the driven component 3 to slide relative to the pushing part 23, transmitting the pushing force and more effectively propelling the movement of the driven component 3. Moreover, as the conical pushing part 23 continuously pushes the driven component 3 upward, as the circumference of the contact surface between the pushing part 23 and the driven component 3 continuously increases, the pushing part 23 will eventually be jammed by the driven component 3 as it moves along the insertion direction of the second sliding part 2. This prevents the second sliding part 2 from reaching the top of the first sliding cavity 11, thus preventing the damping device from being punctured.

[0045] An embodiment of the present invention also provides a vehicle, including a vehicle body and a shock-absorbing device disposed on the vehicle body, wherein the shock-absorbing device is the shock-absorbing device in the above embodiment.

[0046] The vehicle in this embodiment includes a vehicle body and a shock absorber mounted on the vehicle body. The shock absorber is the same as the one described in the previous embodiment. During operation, this type of vehicle can convert the kinetic energy generated by the vibration of the shock absorber into electrical energy for use by the vehicle's electrical system.

[0047] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0048] The application provides a damping device, which comprises a first sliding part 1, a first sliding cavity 11 and an opening part 12 in communication with the first sliding cavity 11; a second sliding part 2, the second sliding part 2 has a second sliding cavity 21, the second sliding part 2 is inserted into the first sliding cavity 11 through the opening part 12, so that the first sliding part 1 and the second sliding part 2 are arranged in relative sliding mode; a driven part 3, the driven part 3 is movably arranged on the first sliding part 1 relative to the first sliding part 1, and one end of the driven part 3 is located in the first sliding cavity 11; wherein the outer wall of the second sliding part 2 is sealingly connected with the inner wall of the first sliding part 1, the second sliding part 2 is provided with a communication hole 22 for communicating the second sliding cavity 21 and the first sliding cavity 11; the first sliding cavity 11 and the second sliding cavity 21 are filled with damping liquid, so that the driven part 3 moves relative to the first sliding part 1 when the pressure in the first sliding cavity 11 increases. The damping device solves the problem that the existing shock absorber is difficult to utilize the offset energy and energy is wasted.

[0049] The above merely describes the preferred embodiments of the present application and is not used to limit the present application.
