Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a shock absorber and a vehicle. Background Art

[0002] The main function of the shock absorber is to absorb the impact force caused by the excitation of the potholes and the elastic potential energy of the elastic deformation of the spring when the vehicle is driving on a bumpy road, and convert it into damping force to do work, and then convert it into heat energy and evaporate it into the air, thereby absorbing and weakening the impact force of the road, thereby improving the comfort and stability of the vehicle.

[0003] When the outside temperature is high, the initial temperature of the shock absorber will be high. The heat energy generated by the shock absorber cannot be dissipated in the air. If the shock absorber is in a high temperature environment for a long time, the damping force will be reduced, affecting the performance of the shock absorber. More seriously, it will cause internal non-metallic components to burn, resulting in oil leakage, shock absorber failure and other problems. Utility Model Content

[0004] The present application provides a shock absorber and a vehicle to solve the above technical problems.

[0005] The embodiment of the present application is implemented as follows:

In this way, the coolant can be cooled by the cold air component, so that the coolant entering the receiving chamber can maintain a low temperature, further improving the heat dissipation efficiency of the shock absorber.

[0013] In a possible implementation manner: along the axial direction of the damping cylinder, the liquid inlet and the liquid outlet are staggered so that the coolant can flow through various areas of the accommodating cavity as much as possible to fully absorb the heat generated by the damping cylinder.

[0014] In a possible implementation manner: the heat dissipation device further includes a driving member, which is connected to the liquid inlet and is configured to transport the cooling liquid to the liquid inlet.

[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0055] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0056] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present embodiment provides a shock absorber 100, comprising a shock absorbing cylinder 10 and a heat dissipation device 20 disposed on the periphery of the shock absorbing cylinder 10. The heat dissipation device 20 comprises a heat dissipation housing 21 and a plurality of heat dissipation fins 23. The heat dissipation housing 21 is sleeved on the periphery of the shock absorbing cylinder 10. A receiving chamber 22 is provided in the heat dissipation housing 21, or a receiving chamber 22 is formed between the heat dissipation housing 21 and the shock absorbing cylinder 10. A coolant is arranged in the receiving chamber 22. A plurality of heat dissipation fins 23 are connected to the outer surface of the heat dissipation housing 21, and the plurality of heat dissipation fins 23 are distributed at intervals. When the receiving chamber 22 is disposed inside the heat dissipation housing 21, the coolant can perform heat exchange with the shock absorbing cylinder 10 through the heat dissipation housing 21, and absorb the heat generated by the shock absorbing cylinder 10. When the receiving chamber 22 is formed between the heat dissipation housing 21 and the shock absorbing cylinder 10, the coolant can directly contact the shock absorbing cylinder 10 for heat exchange. The heat dissipation fins 23 can increase the heat dissipation area of ​​the heat dissipation housing 21, allowing the heat absorbed by the coolant to evaporate into the external air through the heat dissipation fins 23, superimposing air cooling on the basis of liquid cooling, thereby reducing the temperature of the shock absorber 100 faster and more effectively.

[0057] like Figures 1 to 3 As shown, in some embodiments, a plurality of heat dissipation fins 23 extend along the axial direction of the vibration damping cylinder 10, and the plurality of heat dissipation fins 23 are spaced apart along the circumferential direction of the vibration damping cylinder 10, so as to reasonably utilize the outer surface space of the heat dissipation housing 21, effectively increase the heat dissipation area, and enhance the air cooling heat dissipation effect. An air flow channel 231 is formed between adjacent heat dissipation fins 23, and when the external air flows through the air flow channel 231, it can fully contact the heat dissipation fins 23, so as to take away the heat of the heat dissipation fins 23 and reduce the temperature of the heat dissipation fins 23.

[0058] like Figure 3 As shown, in one embodiment, the number of heat dissipation fins 23 is twelve, evenly distributed around the circumference of the heat dissipation housing 21. In other embodiments, the number of heat dissipation fins 23 can be more or less than twelve, as long as the heat dissipation requirements are met, and the present application is not limited thereto.

[0059] In some embodiments, each heat dissipation fin 23 is further provided with a heat dissipation cavity, that is, the heat dissipation fin 23 may be a hollow structure. The heat dissipation cavity in the heat dissipation fin 23 is connected to the receiving cavity 22. In this way, the heat dissipation area of ​​the heat dissipation fin 23 can be increased inside, so that the coolant in the receiving cavity 22 can fully contact with the heat dissipation fin 23, further improving the heat dissipation efficiency.

[0060] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the heat dissipation housing 21 is further provided with a liquid inlet 211 and a liquid outlet 212, and the liquid inlet 211 and the liquid outlet 212 are respectively connected to the receiving chamber 22. The liquid inlet 211 is used to inject coolant into the receiving chamber 22, and the liquid outlet 212 is used to discharge coolant from the receiving chamber 22. Along the axial direction of the damping cylinder 10, the liquid inlet 211 and the liquid outlet 212 are staggered. In one embodiment, as Figure 3 and Figure 4 As shown, the liquid inlet 211 is arranged near the bottom of the heat dissipation housing 21, and the liquid outlet 212 is arranged near the top of the heat dissipation housing 21, so that the height of the liquid inlet 211 is lower than the height of the liquid outlet 212. Along the radial direction of the damping cylinder 10, the projections of the liquid inlet 211 and the liquid outlet 212 at the bottom of the heat dissipation housing 21 are arranged roughly symmetrically. In this way, when the coolant is injected into the receiving cavity 22 from the liquid inlet 211, it can gradually flow upward from the lower area of ​​the receiving cavity 22, and flow out from the liquid outlet 212 after roughly filling the receiving cavity 22, so that the coolant flows through various areas of the receiving cavity 22 as much as possible, and fully absorbs the heat generated by the damping cylinder 10.

[0061] In some embodiments, the damping cylinder body 10 includes a damping hydraulic cylinder 11 and an oil storage cylinder 12. The oil storage cylinder 12 is sleeved on the periphery of the damping hydraulic cylinder 11, and the inner surface of the oil storage cylinder 12 can contact the outer surface of the damping hydraulic cylinder 11 for heat exchange. The heat dissipation shell 21 is sleeved on the periphery of the oil storage cylinder 12. The oil storage cylinder 12 is used to absorb the heat of the damping hydraulic cylinder 11 and cool the damping hydraulic cylinder 11. The heat dissipation shell 21 and the heat dissipation fins 23 are arranged on the periphery of the oil storage cylinder 12, and the oil storage cylinder 12 is cooled by a double cooling method to avoid excessive temperature of the oil storage cylinder 12, so as to maintain the temperature stability of the damping hydraulic cylinder 11, thereby improving the performance of the shock absorber 100. When the receiving chamber 22 is arranged inside the heat dissipation shell 21, the inner surface of the heat dissipation shell 21 contacts the outer surface of the oil storage cylinder 12, and the heat of the oil storage cylinder 12 is transferred to the coolant through the inner surface of the heat dissipation shell 21. The coolant takes away the heat of the oil storage cylinder 12 during the flow in the receiving chamber 22 to reduce the temperature of the oil storage cylinder 12.

[0062] In some embodiments, the receiving chamber 22 is formed between the heat dissipation housing 21 and the oil storage cylinder 12, and along the axial direction of the damping cylinder 10, the two ends of the heat dissipation housing 21 are respectively sealed and connected to the outer surface of the oil storage cylinder 12 to prevent the coolant from leaking from the two ends of the heat dissipation housing 21. In this way, the coolant in the receiving chamber 22 can directly contact the damping cylinder 10, absorb the heat of the damping cylinder 10, and help improve the heat dissipation efficiency.

[0063] Please refer again Figures 1 to 4 In some embodiments, the damping cylinder 10 further includes a hydraulic rod 13 and a boss 14. Along the axial direction of the damping hydraulic cylinder 11, the hydraulic rod 13 is mounted on one end of the damping hydraulic cylinder 11 and is movably matched with the damping hydraulic cylinder 11 to form a part of the damping structure in the shock absorber 100. The boss 14 is arranged around the periphery of the oil storage cylinder 12 and is fixedly connected to the oil storage cylinder 12. Along the axial direction of the damping hydraulic cylinder 11, the heat dissipation housing 21 is spaced apart from the boss 14, and the heat dissipation housing 21 is located on the side of the boss 14 away from the protruding end of the hydraulic rod 13. The boss 14 is used to install a damping spring (not shown in the figure). The heat generated by the damping spring when doing work can be transferred to the oil storage cylinder 12 through the boss 14, and then transferred to the heat dissipation device 20 through the oil storage cylinder 12. The heat is quickly taken away by the heat dissipation device 20, thereby reducing the overall temperature of the shock absorber 100. A spring mounting surface 15 is also provided on one side of the boss 14 that extends toward the hydraulic rod 13. The spring mounting surface 15 is substantially spiral-shaped to match the structure of the damping spring and facilitate the positioning of the damping spring.

[0064] See also Figure 6 and Figure 7 In some embodiments, the heat dissipation device 20 further includes an air conditioning system 30, and the receiving chamber 22 is connected to the air conditioning system 30. In this way, the coolant in the receiving chamber 22 can be transported to the air conditioning system 30 for secondary use, which is beneficial to saving energy; or, the coolant is cooled by the air conditioning system 30, without the need to set up additional cooling equipment for the coolant.

[0065] Specifically, see Figure 6In one embodiment, the air conditioning system 30 includes a hot air component 31 and a compressor 32, and the hot air component 31 is connected to the compressor 32. The heat dissipation device 20 also includes a liquid inlet pipe 24 and a liquid outlet pipe 25, the liquid inlet pipe 24 is connected to the liquid inlet 211, and the liquid outlet pipe 25 is connected to the liquid outlet 212 and the hot air component 31. In this way, the coolant with a higher temperature flowing out of the receiving chamber 22 can be reused in the hot air component 31, and the coolant with a higher temperature exchanges heat with the airflow in the hot air component 31, so that the coolant with a higher temperature can assist in heating the airflow in the hot air component 31, increase the hot air temperature of the hot air component 31, reduce the work done by the air conditioning system 30, improve energy utilization, reduce the vehicle's own engine load, improve engine efficiency, and for electric vehicles, reduce power consumption, thereby achieving the purpose of saving energy. The temperature of the coolant after secondary use in the hot air component 31 is reduced, and can be introduced into the liquid inlet pipe 24 through other pipes to recycle the coolant. In other embodiments, the liquid inlet pipe 24 may also be connected to other liquid supply devices, and the coolant after secondary use in the hot air component 31 is introduced into other external devices for processing or reuse, but the present application is not limited to this.

[0066] See also Figure 7 In one embodiment, the air conditioning system 30 includes a cold air component 33 and a compressor 32, and the cold air component 33 is connected to the compressor 32. The liquid inlet pipe 24 of the heat dissipation device 20 connects the liquid inlet 211 and the cold air component 33, and the liquid outlet pipe 25 connects the liquid outlet 212 and the cold air component 33. In this way, the coolant can be cooled by the cold air component 33, so that the coolant entering the receiving chamber 22 can maintain a relatively low temperature, further improving the heat dissipation efficiency of the shock absorber 100. In other embodiments, the liquid outlet pipe 25 may not be connected to the cold air component 33. In this case, the liquid outlet pipe 25 can be connected to the liquid outlet 212 and the hot air component 31 or other external equipment, so that the coolant with a higher temperature can be reused in the hot air component 31 or other external equipment.

[0067] See also Figure 6 and Figure 7 In some embodiments, the heat dissipation device 20 further includes a driving member 26, which is connected to the liquid inlet 211 and can be communicated with the liquid inlet 211 through the liquid inlet pipe 24. The driving member 26 is configured to transport the coolant to the liquid inlet 211 to provide power for the coolant to flow.

[0068] See also Figure 8 An embodiment of the present application further provides a vehicle 200 , comprising a vehicle body 201 and the shock absorber 100 described in the above embodiment, wherein the shock absorber 100 is installed on the vehicle body 201 .

[0069] The shock absorber 100 of the present application and the vehicle 200 having the shock absorber 100 perform liquid cooling and air cooling on the shock absorber cylinder 10 through the combination of the heat dissipation housing 21 and the heat dissipation fins 23, thereby increasing the heat dissipation area and realizing double cooling, fully improving the heat dissipation efficiency of the shock absorber 100, and solving the problem of high-temperature failure of the shock absorber 100.

[0070] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
