DETAILED DESCRIPTION

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, the directional words such as "up", "down", "left", "right", etc. used to indicate directions or positional relationships are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation. Therefore, it cannot be understood as a limitation on the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.

[0028] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0029] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0030] refer to Figures 1 to 6 As shown, the first aspect of the present disclosure provides a shock absorber 1, including a heating component 2 and a body 3, the body 3 including a first cylinder 31, a second cylinder 32, a piston component 34 and a temperature adjustment module, the first cylinder 31 has a first chamber 310, the second cylinder 32 is sleeved outside the first cylinder 31, the second cylinder 32 has a second chamber 320, the piston component 34 includes a piston 341 and a piston rod 342, the piston 341 and the piston rod 342 can be inserted into the first chamber 310 movably up and down, and the first chamber 310 is divided into an upper chamber 311 and a lower chamber 312, the temperature adjustment module includes a heating component 2 and / or a cooling component 7, the heating component 2 is used to heat the body 3 to heat the medium located in the first chamber 310; the cooling component 7 is used to cool the body 3 using the coldness of the vehicle thermal management system.

[0031] By setting up a temperature adjustment module, when the temperature of the main body is low, the heating component 2 can heat the main body 3, thereby realizing rapid heating of the medium in the first chamber 310, so that the medium is within an optimal temperature range, thereby reducing the damping force of the shock absorber 1, ensuring the kinematic viscosity of the medium in the shock absorber 1, and better ensuring the vehicle's handling performance and comfort performance; when the temperature of the main body is high, the cooling component 7 can cool the main body 3, thereby reducing the risk of failure of the shock absorber 1 due to excessive temperature.

[0032] In addition, in the process of cooling the above-mentioned body, the cooling capacity of the existing vehicle thermal management system is utilized. On the one hand, there is no need to set up related cooling components separately, which reduces additional hardware investment and reduces the weight of the vehicle. On the other hand, the shock absorber cooling is integrated with the vehicle thermal management system, making the entire system more compact and integrated, reducing failure points and maintenance difficulties.

[0033] The present disclosure does not limit the connection and matching relationship between the heating component 2 and the above-mentioned body 3. For example, in an embodiment provided by the present disclosure, the heating component 2 can be optionally connected to the second cylinder 32 and / or the piston component 34. That is, the heating component 2 can be connected to the second cylinder 32. At this time, the heat of the heating component 2 can be transferred to the medium in the first cylinder 31 through the second cylinder 32 and the first cylinder 31 in sequence, so as to heat the medium; or Figure 1 , Figure 5 as well as Figure 6 As shown, the heating component 2 can also be directly connected to the piston component 34. In this way, since the piston component 34 is located in the first chamber 310 and in contact with the medium, the heat can be quickly transferred to the medium through the piston component 34 to achieve heating of the medium. Alternatively, the heating component 2 can also be connected to both the second cylinder body 32 and the piston component 34. The heating component 2 heats the second cylinder body 32 and the piston component 34 at the same time to further improve the heating efficiency of the oil.

[0034] In another embodiment provided in the present disclosure, the above-mentioned heating component 2 may not be connected to the second cylinder body 32 and / or the piston assembly 34. For example, the heating component 2 and the second cylinder body 32 are arranged opposite to each other and at a distance. The heating component 2 heats the second cylinder body 32 by radiation heat transfer or convection heat transfer.

[0035] In addition, the present disclosure does not limit the specific heating structure of the heating component 2. For example, in an exemplary embodiment provided by the present disclosure, Figure 1 , Figure 5 as well as Figure 6As shown, the heating assembly 2 may include a heating element 21 and a control circuit 22 connected to each other, and a heating hole 3420 extending along the axial direction of the piston rod 342 is formed inside the piston rod 342, and the heating element 21 is inserted into the heating hole 3420. On the one hand, the heating element 21 is inserted into the heating hole 3420 formed inside the piston rod 342 to heat the piston rod 342, so that the heating element 21 does not occupy the internal space of the first chamber 310, and the setting of the heating element 21 can avoid interference or interference with the compression and recovery of the piston assembly 34. On the other hand, since the size of the piston rod 342 is relatively small, when the heating element 21 heats the piston rod 342 from the inside of the piston rod 342, the heat can be conducted to the medium through the piston rod 342 more quickly.

[0036] In order to facilitate the maintenance and inspection of the above-mentioned heating element 21, the above-mentioned heating element 21 can be connected to the above-mentioned heating hole 3420 in a detachable manner. For example, the heating element 21 can be snapped into the heating hole 3420, or, an external thread can be formed on the outer surface of the heating element 21, and an internal thread can be provided on the hole wall of the heating hole 3420, and the heating element 21 is connected to the heating hole 3420 by threading.

[0037] In order to make the heating element 21 fit the hole wall of the heating hole 3420 as closely as possible, the shape and size of the heating element 21 should be compatible with the shape and size of the heating hole 3420. For example, in one embodiment of the present disclosure, the heating hole 3420 is formed as a columnar structure with a circular cross-section, and the heating element 21 is correspondingly formed as a columnar structure.

[0038] In one embodiment provided by the present disclosure, the heating element 21 may be made of a resistive material (such as a nickel-chromium alloy) so as to generate heat when an electric current passes through it.

[0039] In order to further improve the heating efficiency of the heating element 21, a thermal conductive adhesive is filled between the outer wall of the heating element 21 and the inner wall of the heating hole 3420. That is, after the heating element 21 is installed in the heating hole 3420, the thermal conductive adhesive is filled between the heating element 21 and the heating hole 3420, thereby reducing the air gap, reducing the thermal resistance, and allowing the heat to be more effectively transferred from the heating element 21 to the piston rod 342 and the medium.

[0040] In addition, the thermally conductive adhesive is usually electrically insulating, which can prevent short circuits and improve the safety of the shock absorber 1 during operation.

[0041] It should be noted that, with respect to the implementation mode in which the cooling component 7 utilizes the cold energy of the vehicle thermal management system to cool down the main body, there is no restriction on the type of the vehicle thermal management system. For example, the cooling component 7 can utilize the cold energy of the vehicle's engine cooling system, battery thermal management system, transmission cooling system, etc. to achieve cooling and heat dissipation of the main body 3, or the cooling component 7 can also utilize the cold energy of the vehicle's air-conditioning system to achieve cooling and heat dissipation of the main body 3.

[0042] Similarly, the present disclosure does not impose any restrictions on the connection and cooperation relationship between the above-mentioned cooling component 7 and the main body 3. For example, the cooling component 7 can be spaced apart from the main body 3 to dissipate heat from the shock absorber 1 by convection. Alternatively, the cooling component 7 can also be directly attached to the main body 3, that is, the heat from the main body 3 is dissipated by contact cooling. In short, as long as heat exchange with the main body 3 can be achieved, it will be fine.

[0043] For the implementation method in which the cooling component 7 utilizes the cooling capacity of the vehicle's air conditioning system to cool and dissipate the heat of the body 3, as shown in FIG. Figure 4 As shown, the cooling assembly 7 includes an evaporator 70, a first connecting pipe 71 and a second connecting pipe 72. The evaporator 70 is connected to the condenser 200 of the air conditioning system of the vehicle thermal management system through the first connecting pipe 71. One end of the second connecting pipe 72 is connected to the first connecting pipe 71, and the other end of the second connecting pipe 72 is used to communicate with the compressor of the air conditioning system. In this way, in the process of cooling and dissipating the heat of the body 3, the low-pressure and low-temperature liquid refrigerant enters the evaporator 70. In the evaporator 70, the refrigerant absorbs the heat of the body 3 and evaporates into gas. The evaporated low-pressure gas refrigerant is sucked by the compressor and compressed into high-temperature and high-pressure gas, and then flows into the condenser 200 of the air conditioning system. In the condenser 200, the refrigerant releases heat and cools and condenses into liquid through heat exchange with the external air. The liquid refrigerant drops in pressure after passing through the expansion valve, becomes a low-pressure and low-temperature liquid, and re-enters the evaporator 70, starting a new round of circulation to achieve cyclic heat exchange of the body 3.

[0044] In the above scheme, on the one hand, the existing air-conditioning system is utilized, and there is no need to separately set up an additional condenser 200 and a compressor, so that the integrated design of the system can be realized, which reduces the additional hardware investment and reduces the weight of the whole vehicle. On the other hand, the cooling of the shock absorber 1 is integrated with the air-conditioning system, making the whole system more compact and integrated, reducing the failure points and the difficulty of maintenance.

[0045] In addition, if Figure 4As shown, an air-conditioning refrigeration refrigerant channel control switch 6 is also provided in the above-mentioned first connecting pipe 71. When the temperature of the main body 3 is high, the air-conditioning refrigeration refrigerant channel control switch 6 can be turned on. At this time, the refrigerant can circulate between the evaporator 70, the compressor and the condenser 200 to achieve cyclic cooling of the stack body 3; when there is no need to cool the main body 3 or the temperature of the main body 3 is maintained within a suitable range, the air-conditioning refrigeration refrigerant channel control switch 6 can be adjusted to a closed state, and the damper temperature will not be affected by the air-conditioning system, nor will it cause waste of cooling capacity of the air-conditioning system.

[0046] The present disclosure does not limit the specific structure, shape and matching relationship between the evaporator 70 and the body 3. For example, in an embodiment provided by the present disclosure, Figures 1 to 6 As shown, the evaporator 70 may include a heat exchange tube 701, and the heat exchange tube 701 is arranged around the circumference of the second cylinder 32. On the one hand, the heat exchange tube 701 arranged around the circumference of the second cylinder 32 can increase the contact area with the second cylinder 32, thereby improving the heat exchange efficiency. On the other hand, the surrounding heat exchange tube 701 can be more evenly distributed around the second cylinder 32, thereby reducing the temperature gradient, ensuring that the temperature distribution inside and outside the second cylinder 32 is more uniform, avoiding local overheating or overcooling, and the surrounding design can effectively utilize space, especially in a limited installation space, the heat exchange tube 701 can be arranged more compactly.

[0047] Furthermore, if Figures 1 to 6 As shown, the evaporator 70 may further include a heat exchange plate 702, which is attached to the outer wall of the second cylinder 32, and a heat exchange tube 701 is attached to the outer wall of the heat exchange plate 702. Compared with the heat exchange tube 701 disposed around the outer wall of the second cylinder 32, the heat exchange plate 702 attached to the outer periphery of the second cylinder 32 can further increase the contact area with the second cylinder 32 and reduce the heat exchange dead angle, and the contact between the heat exchange plate 702 and the outer wall of the second cylinder 32 is a surface-to-surface contact, while the contact between the heat exchange tube 701 and the outer wall of the second cylinder 32 is a line-to-surface contact. The surface-to-surface contact can better adapt to the situation of uneven surface or shape change, does not need to accurately control the position of the contact point, and can more easily achieve high-precision docking and matching, reduce processing errors, improve assembly accuracy, and reduce processing difficulty.

[0048] In order to make the heat exchange tube 701 and the heat exchange plate 702 fit closely together, in an exemplary embodiment provided by the present disclosure, the heat exchange tube 701 and the heat exchange plate 702 can be connected by bonding, welding, etc., or, in another exemplary embodiment provided by the present disclosure, the heat exchange plate 702 and the heat exchange tube 701 can also be manufactured as an integral molding. The integral molding design can reduce the contact thermal resistance between the heat exchange tube 701 and the heat exchange plate 702, and the heat can be transferred more directly from the heat exchange plate 702 to the heat exchange tube 701, thereby improving the heat exchange efficiency. In addition, the integral molding structure is usually stronger than separately manufactured components, can withstand higher pressures and temperatures, and can reduce the risk of leakage that may occur due to welding or connections.

[0049] Alternatively, if Figure 1 , Figure 3 , Figure 5 as well as Figure 6 As shown, the shock absorber 1 may further include a temperature sensor 5, the detection head of the temperature sensor 5 is located in the first chamber 310, and is used to detect the temperature of the medium in the first chamber 310. The detection head of the temperature sensor 5 disposed in the first chamber 310 can detect the temperature of the medium in real time and quickly. After the driver sees the temperature information measured by the temperature sensor 5, he can turn on or off the heating component 2 and the cooling component 7 to quickly adjust the temperature of the medium in the first chamber 310.

[0050] It should be noted that the present disclosure does not limit the specific position of the detection head of the above-mentioned temperature sensor 5 in the first chamber 310. The detection head can be set in the upper chamber 311 or the lower chamber 312. In short, as long as the detection of the medium temperature in the first chamber 310 can be achieved.

[0051] Optionally, the shock absorber 1 may further include a controller, which is respectively connected to the temperature sensor 5, the heating component 2, and the cooling component 7 by signals, and can start the cooling component 7 when the temperature collected by the temperature sensor 5 is greater than a preset temperature range, and start the heating component 2 when the temperature collected by the temperature sensor 5 is less than the preset temperature range. In this way, according to the temperature information collected by the temperature sensor 5, the controller can control the heating component 2 and the cooling component 7 to turn on or off, thereby realizing automatic adjustment of the oil temperature, with higher sensitivity and adjustment accuracy.

[0052] For the above-mentioned implementation mode in which the controller is respectively connected with the temperature sensor 5, the heating component 2 and the cooling component 7 by signals, the controller can respectively connect with the temperature sensor 5, the heating component 2 and the cooling component 7 by means of data lines or the like (wired method), or can connect with the temperature sensor 5, the heating component 2 and the cooling component 7 by wireless means such as Bluetooth and wireless LAN.

[0053] Alternatively, if Figure 1 , Figure 3 as well as Figures 4 to 6 As shown, the shock absorber 1 also includes a compression solenoid valve 8, a restoration solenoid valve 9 and a third cylinder body 33. The third cylinder body 33 is sleeved outside the first cylinder body 31, and the second cylinder body 32 is sleeved outside the third cylinder body 33. A first flow channel 330 is formed between the inner cylinder wall of the third cylinder body 33 and the outer cylinder wall of the first cylinder body 31, and a second flow channel 331 is formed between the inner cylinder wall of the second cylinder body 32 and the outer cylinder wall of the third cylinder body 33. The first flow channel 330 and the second flow channel 331 are both connected to the upper chamber 311; the compression outlet 81 of the compression solenoid valve 8 and the restoration inlet 92 of the restoration solenoid valve 9 are both connected to the lower chamber 312, the compression inlet 82 of the compression solenoid valve 8 is connected to the first flow channel 330, and the restoration outlet 91 of the restoration solenoid valve 9 is connected to the second flow channel 331.

[0054] Specifically, in the compression state, under the action of the piston assembly 34, the medium located in the upper chamber 311 flows upward and flows into the compression inlet 82 of the compression solenoid valve 8 through the first flow channel 330, and flows into the lower chamber 312 from the compression outlet 81 of the compression solenoid valve 8. In the above process, the compression solenoid valve 8 can adjust the damping of the shock absorber 1; and in the recovery state, under the action of the piston assembly 34, the medium located in the lower chamber 312 flows downward and flows into the recovery solenoid valve 9 through the recovery inlet 92 of the recovery solenoid valve 9, and then flows into the second flow channel 331 from the recovery outlet 91 of the recovery solenoid valve 9, and finally, flows into the upper chamber 311 from the second flow channel 331. In the process of the medium flowing through the recovery solenoid valve 9, the recovery solenoid valve 9 can adjust the damping of the shock absorber 1.

[0055] In order to prevent the medium in the upper chamber 311 from entering the second flow channel 331 during the compression process and affecting the damping adjustment effect of the compression solenoid valve 8, a one-way valve 15 can be set at the above-mentioned second flow channel 331. The one-way valve 15 can allow the medium to flow only from the second flow channel 331 to the upper chamber 311, but cannot allow the medium to flow from the upper chamber 311 to the second flow channel 331.

[0056] Alternatively, if Figure 2As shown, the shock absorber 1 may also include a first valve component 10 and a second valve component 11. In the stretched state, the first valve component 10 can allow the medium in the lower chamber 312 to flow into the upper chamber 311; in the compressed state, the second valve component 11 can allow the medium in the upper chamber 311 to flow into the lower chamber 312. When the shock absorber 1 is in the stretched state, the volume of the lower chamber 312 decreases and the pressure increases. At this time, under the action of pressure, the medium in the lower chamber 312 flows into the upper chamber 311 through the first valve component 10, thereby preventing the shock absorber from being damaged by excessive damping force; similarly, when the shock absorber 1 is in the compressed state, the volume of the upper chamber 311 decreases and the pressure increases. At this time, under the action of pressure, the medium in the upper chamber 311 flows into the lower chamber 312 through the second valve component 11, thereby preventing the shock absorber from being damaged by excessive damping force.

[0057] In order to facilitate the medium to flow from the upper chamber 311 to the lower chamber 312 in the compressed state, or to flow from the lower chamber 312 to the upper chamber 311 in the restored state, optionally, as Figure 2 As shown, a first through hole 3410 and a second through hole 3411 are formed on the piston 341, the first end of the first through hole 3410 and the first end of the second through hole 3411 are connected to the upper chamber 311, the second end of the first through hole 3410 and the second end of the second through hole 3411 are connected to the lower chamber 312, the first valve part 10 is used to connect or cut off the first through hole 3410, and the second valve part 11 is used to connect or cut off the second through hole 3411. Specifically, when the shock absorber 1 is in a stretched state, the volume of the lower chamber 312 decreases and the pressure increases. At this time, the first valve component 10 is connected to the first through hole 3410, and the medium can flow into the upper chamber 311 through the first through hole 3410. When the shock absorber 1 is in a compressed state, the volume of the upper chamber 311 decreases and the pressure increases. At this time, the second valve component 11 is connected to the second through hole 3411, and the medium in the upper chamber 311 can flow into the lower chamber 312 through the second through hole 3411 to prevent the shock absorber from being damaged by excessive damping force.

[0058] The present disclosure does not limit the specific structure and type of the valve component. In one embodiment provided in the present disclosure, Figure 2As shown, the first valve component 10 may include a first elastic baffle 101, which is located in the upper chamber 311, and the first elastic baffle 101 can cover or expose the first end of the first through hole 3410; the second valve component 11 includes a second elastic baffle 111, which is located in the lower chamber 312, and the second elastic baffle 111 can cover or expose the second end of the second through hole 3411; in the stretched state, the medium pressure in the lower chamber 312 is greater than the medium pressure in the upper chamber 311, the medium in the lower chamber 312 flows into the first through hole 3410 and pushes the first elastic baffle 101 to deform, so as to expose the first end of the first through hole 3410, and in the compressed state, the medium pressure in the upper chamber 311 is greater than the medium pressure in the lower chamber 312, the medium in the upper chamber 311 flows into the second through hole 3411 and pushes the second elastic baffle 111 to deform, so as to expose the second end of the second through hole 3411.

[0059] Alternatively, in other embodiments provided in the present disclosure, the first valve component 10 and the second valve component 11 may also be solenoid valves. Thus, when the shock absorber 1 is in a stretched state, the volume of the lower chamber 312 decreases and the pressure increases. At this time, when the pressure on the first valve component 10 reaches a certain preset pressure value, the first valve component 10 automatically opens, and the medium can flow into the upper chamber 311 through the first through hole 3410. Similarly, when the shock absorber 1 is in a compressed state, the volume of the upper chamber 311 decreases and the pressure increases. At this time, when the pressure on the second valve component 11 reaches a certain preset pressure value, the second valve component 11 automatically opens, and the medium can flow into the lower chamber 312 through the second through hole 3411, thereby preventing the damping force from being excessively large and damaging the shock absorber.

[0060] It should be noted that the medium mentioned above can be a liquid fluid (such as oil, etc.) or a gas fluid (such as air, etc.). In short, it can be selected according to the specific usage scenario, and the present disclosure does not limit this.

[0061] In addition, if Figure 1 , Figures 5 and 6 As shown, a positioning ring 16 and a buffer are also provided in the first chamber 310 . The positioning ring 16 can improve the assembly accuracy of the piston rod 342 , and the buffer can buffer the movement of the piston assembly 34 in the first chamber 310 .

[0062] like Figure 1 , Figures 4 to 6As shown, the shock absorber 1 may further include a fixed yoke 13 and a fixed bolt 14, wherein the fixed yoke 13 is connected to one end of the piston rod 342 away from the second cylinder body 32 and is used to be connected to the suspension system of the vehicle when the shock absorber 1 is assembled to the vehicle, and the fixed bolt 14 is connected to one end of the second cylinder body 32 away from the piston rod 342 and is used to be connected to the frame when the shock absorber 1 is assembled to the vehicle.

[0063] The second aspect of the present disclosure provides a vehicle, comprising the shock absorber 1 as described above. In an embodiment where the shock absorber 1 comprises a cooling assembly 7, and the cooling assembly 7 comprises an evaporator 70, a condenser 200 of the air conditioning system of the vehicle is connected to the evaporator 70 via a first connecting pipe 71, and a compressor of the air conditioning system of the vehicle is connected to the evaporator 70 via a second connecting pipe 72, and the air conditioning system of the vehicle has all the beneficial effects of the shock absorber 1 described above, which will not be elaborated on in the present disclosure.

[0064] Optionally, the end of the second cylinder 32 away from the piston rod 342 is connected to the vehicle frame, and the end of the piston rod 342 away from the second cylinder 32 is connected to the suspension system. Compared with the existing vehicle in which the end of the second cylinder 32 away from the piston rod 342 is connected to the suspension system, and the end of the piston rod 342 away from the second cylinder 32 is connected to the vehicle frame, since the second cylinder 32 is fixed to the vehicle frame, the second cylinder 32 will not move relative to the vehicle frame during the operation of the vehicle. In this way, for the embodiment in which the heat exchange tube 701 and the heat exchange plate 702 are arranged on the second cylinder 32, the vibration of the heat exchange tube 701 and the heat exchanger can be reduced, thereby improving the stability and service life of the cooling assembly 7.

[0065] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0066] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0067] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
