Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and more specifically to a wear-resistant spring shock absorber. Background Technology

[0002] A spring damper is a device used to suppress the oscillations caused by the spring's rebound after absorbing shocks and to absorb road impacts. It is commonly used in automotive suspension systems. Its main function is to improve the ride comfort of a vehicle by suppressing the rebound of the spring after absorbing shocks and absorbing impacts from the road surface, thereby reducing vehicle vibrations during driving and improving driving comfort and stability.

[0003] In winter, due to the drop in temperature, the viscosity of the damping oil in the shock absorber cylinder increases and its fluidity decreases, which can cause the overall response of the shock absorber to be less sensitive or even stiff. In hot seasons, the heat in some shock absorber cylinders cannot be dissipated quickly, which can have a significant impact on the wear resistance and damping performance of the shock absorber. Utility Model Content

The input end of the water pump is fixedly connected to the drain nozzle, the output end of the water pump is fixedly connected to one end of the heat exchange tube, and the other end of the heat exchange tube is fixedly connected to the inlet nozzle.

[0009] Preferably, fins are fixedly installed on the surface of the heat exchange tube, and multiple fins are evenly arranged. The fixing frame is fixedly connected to the fins, and a through hole is opened on the fixing frame. A fan is fixedly installed on the side of the through hole away from the fins.

The control module analyzes the electrical signals and issues corresponding instructions based on the analysis results. When the cylinder temperature is lower than the standard value, the control module controls the heating wire to turn on, and the heat of the heating wire is transferred to the inside of the cylinder. When the cylinder temperature is higher than the standard value, the control module controls the water pump and fan to turn on. The coolant circulates along the heat conduction pipe and the heat exchange pipe. When the coolant flows through the heat conduction pipe, the heat of the cylinder is transferred to the coolant.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The wear-resistant spring shock absorber involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a wear-resistant spring shock absorber, including a cylinder 1, a piston slidably mounted inside the cylinder 1, a piston rod 2 fixedly mounted on the top of the piston, the top of the piston rod 2 passing through the top of the cylinder 1 and extending upward, a spring 3 sleeved on the surface of the piston rod 2, a mounting shell 4 fixedly connected to the surface of the cylinder 1, a silicone thermal pad 5 and a heat-conducting pipe 7 disposed inside the mounting shell 4, the silicone thermal pad 5 being sleeved on the surface of the cylinder 1, a heating wire 6 mounted on the silicone thermal pad 5, a heat exchange assembly 8 mounted on the surface of the mounting shell 4, and a temperature sensor 9 fixedly mounted on the surface of the cylinder 1. During the contraction and extension of the spring 3, the piston slides along the inside of the cylinder 1, converting elastic potential energy into internal energy through damping oil, thereby achieving the purpose of shock absorption. This is existing technology in the field of spring shock absorbers and will not be described in detail here.

[0022] Furthermore, the silicone thermal pad 5 includes an inner thermal conductive layer 51 and an outer thermal conductive layer 52. A threaded groove 53 is provided between the inner thermal conductive layer 51 and the outer thermal conductive layer 52. The heating wire 6 is fixedly installed in the threaded groove 53. The silicone thermal pad 5 can absorb the heat of the cylinder 1, and the heat of the heating wire 6 can also be transferred to the cylinder 1 through the silicone thermal pad 5.

[0023] Furthermore, the heat pipe 7 has a spiral tube structure, and a support frame 41 is fixedly installed inside the mounting shell 4. The support frame 41 is fixedly installed on the surface of the heat pipe 7 and is used to support the heat pipe 7 and improve the stability of the heat pipe 7. Both ends of the heat pipe 7 pass through the inner wall of the mounting shell 4 and extend outward. One end of the heat pipe 7 is fixedly connected to a drain nozzle 71, and the other end of the heat pipe 7 is fixedly connected to a liquid inlet nozzle 72. The heat pipe 7 is wrapped around the surface of the silicone heat-conducting pad 5, and the heat of the cylinder 1 can be transferred to the heat pipe 7 through the silicone heat-conducting pad 5.

[0024] Furthermore, the heat exchange assembly 8 includes a mounting frame 81, a heat exchange tube 82, and a water pump 84. Both the mounting frame 81 and the water pump 84 are fixedly mounted on the surface of the mounting housing 4. The heat exchange tube 82 has an S-shaped curved structure. The input end of the water pump 84 is fixedly connected to the drain nozzle 71, and the output end of the water pump 84 is fixedly connected to one end of the heat exchange tube 82. The other end of the heat exchange tube 82 is fixedly connected to the inlet nozzle 72. Fins 83 are fixedly mounted on the surface of the heat exchange tube 82, and multiple fins 83 are evenly distributed. The mounting frame 81 is fixedly connected to the fins 83, and a through-hole is formed in the mounting frame 81. A fan 85 is fixedly installed on the side of the connecting hole 811 away from the fins 83. The coolant can circulate along the heat conduction pipe 7 and the heat exchange pipe 82. When the coolant flows through the heat conduction pipe 7, the heat of the cylinder 1 is transferred to the coolant through the silicone heat conduction pad 5. The coolant absorbs heat and its temperature rises. When the coolant flows through the heat exchange pipe 82, the heat of the coolant is transferred to the fins 83. The fins 83 absorb heat and their temperature rises. The air from the fan 85 passes through the connecting hole 811 and blows towards the fins 83, accelerating the airflow and dissipating the heat on the fins 83 to the external environment.

[0025] Furthermore, a control module 86 is fixedly installed on the mounting bracket 81. The temperature sensor 9 is electrically connected to the control module 86 via a first line 87, the water pump 84 is electrically connected to the control module 86 via a second line 88, the fan 85 is electrically connected to the control module 86 via a third line 89, and the heating wire 6 is electrically connected to the control module 86 via a fourth line.

[0026] The working principle of this utility model is as follows: The temperature sensor 9 monitors the temperature of the surface of the cylinder 1 in real time. The monitoring result is transmitted to the control module 86 in the form of an electrical signal. The control module 86 analyzes the electrical signal and issues corresponding instructions based on the analysis results. When the temperature of the cylinder 1 is lower than the standard value, the control module 86 controls the heating wire 6 to turn on. The heat of the heating wire 6 is transferred to the silicone heat-conducting pad 5, and the silicone heat-conducting pad 5 then transfers the heat to the inside of the cylinder 1, thereby reducing the viscosity of the damping oil in the cylinder 1 and restoring its fluidity.

[0027] When the temperature of cylinder 1 is higher than the standard value, the control module 86 controls the water pump 84 and the fan 85 to start. Under the action of the water pump 84, the coolant circulates along the heat pipe 7 and the heat exchange pipe 82. When the coolant flows through the heat pipe 7, the heat of cylinder 1 is transferred to the coolant through the silicone heat-conducting pad 5. The coolant absorbs heat and its temperature rises. When the coolant flows through the heat exchange pipe 82, the heat of the coolant is transferred to the fins 83. The fins 83 absorb heat and their temperature rises. The air from the fan 85 passes through the connecting hole 811 and blows towards the fins 83, accelerating the airflow. The heat on the fins 83 is dissipated to the external environment, thereby reducing the temperature of cylinder 1.
