Further, as shown in fig. 4 and 5, the first core 21 is internally formed with a guide cavity 251, the mover assembly includes a guide bar 231 coupled with the guide cavity 251, and the stator assembly further includes: the sliding sleeve 25, the sliding sleeve 25 sets up between direction cavity 251 and guide bar 231, forms cooling flow path 211 between sliding sleeve 25 and the first iron core 21, and the top of guide bar 231 is equipped with the play liquid hole 252 with fluid-discharge opening 215 intercommunication.

Among them, the guide cavity 251 may function to guide the circulation of the cooling medium, and the guide rod 231 mainly functions to slide. The sliding sleeve 25 mainly plays a role in guiding and sealing, the sliding sleeve 25 is arranged between the guide cavity 251 and the guide rod 231, so that the arrangement is more reasonable, the sliding sleeve 25 is convenient to be matched with the guide rod 231, the sliding sleeve 25 can be fixed, the arrangement of the sliding sleeve 25 is firmer and more stable, and the sliding sleeve 25 can work better.

The sliding sleeve 25 and the first core 21 define a cooling flow path 211 therebetween, that is, a gap exists between the sliding sleeve 25 and the first core 21, which gap may form the cooling flow path 211, that is, the sliding sleeve 25 is a partial structure constituting the cooling flow path 211, so that a flow direction of the cooling flow path 211 may be defined in cooperation with a shape of the first core 21, and the cooling flow path 211 may be sealed.

The top of guide bar 231 is provided with the liquid outlet 252 that communicates with fluid outlet 215, sets up fluid outlet 215 at the top of guide bar 231, and it is more reasonable to set up like this, can shorten the distance between fluid outlet 215 and the liquid outlet 252 to the coolant in the guide cavity 251 flows into liquid outlet 252 department through fluid outlet 215.

In addition, as shown in fig. 4 and 5, the mover assembly further includes an outer cylinder 232, the bottom of the guide bar 231 is fixedly connected to the outer cylinder 232, the outer cylinder 232 is sleeved outside the first core 21, and the cooling medium inlet 28 is formed in the outer cylinder 232. Wherein, the urceolus 232 mainly plays the effect of installation and support, with the bottom and urceolus 232 fixed connection of guide bar 231, can make the connection between urceolus 232 and the guide bar 231 more stable like this to the guide bar 231 can be more stable when sliding. The outer cylinder 232 is fitted over the outer side of the first core 21, so that the first core 21 can be protected by the outer cylinder 232, and the first core 21 can be operated more effectively.

Further, as shown in fig. 4, a liquid inlet chamber 24 is defined between the outer cylinder 232 and the first core 21, the liquid inlet chamber 24 communicates with the cooling flow path 211, and the liquid inlet chamber 24 communicates with the external cooling module 80, and the cooling medium in the external cooling module 80 is selectively introduced into the liquid inlet chamber 24 through the cooling medium inlet 28 during the movement of the guide bar 231.

The liquid inlet cavity 24 mainly plays a role of buffering cooling medium, and when the internal environment of the shock absorber module 20 needs to be cooled, the cooling medium buffered in the liquid inlet cavity 24 can flow, so that the cooling of the coil 22 is realized. The cooling flow path 211 is communicated with the liquid inlet cavity 24, and the liquid inlet cavity 24 and the cooling flow path 211 are respectively communicated with the external cooling module 80, that is, the cooling flow path 211, the liquid inlet cavity 24 and the external cooling module 80 can be mutually communicated, so that the recycling of the cooling medium can be realized.

The cooling medium in the external cooling module 80 is selectively introduced into the liquid inlet cavity 24 through the cooling medium inlet 28, and it should be noted that the flow of the cooling medium in the liquid storage tank 10 can be controlled by controlling the sliding of the guide rod 231, specifically, when the guide rod 231 slides upwards, the volume in the liquid inlet cavity 24 is reduced, the pressure is increased, the cooling medium buffered in the liquid inlet cavity 24 can enter into the cooling flow path 211 under the action of the pressure, so that the cooling medium can exchange heat with the first iron core 21 and the coil 22, the cooling of the first iron core 21 and the coil 22 is realized, the cooling medium after heat exchange can be recovered into the liquid storage tank 10 for storage, and the circulation of the cooling medium is convenient. When the guide rod 231 moves downwards, the volume inside the liquid inlet cavity 24 is increased, the pressure is reduced, and the cooling medium in the liquid storage tank 10 can enter the liquid inlet cavity 24 for buffering under the action of the pressure, so that the cooling medium can enter the cooling flow path 211 to exchange heat with the first iron core 21 and the coil 22 when the guide rod 231 moves upwards next time.

In addition, when the guide rod 231 moves upward, the guide rod 231 presses the space above the guide chamber 251, and the pressure above the guide chamber 251 increases, so that the cooling flow path 211 and the cooling medium in the guide chamber 251 can be accelerated to flow out of the damper module 20, and the cooling of the damper module 20 can be accelerated. Also, when the guide rod 231 moves downward, the space above the guide chamber 251 becomes large and the pressure becomes small, so that the cooling medium in the liquid storage tank 10 is caused to enter the liquid inlet chamber 24, and at the same time, the cooling medium in the liquid inlet chamber 24 is caused to flow into the cooling flow path 211 and then into the guide chamber 251, and thus, the flow circulation of the cooling medium can be realized. In the circulation process of the cooling medium, the cooling medium belongs to closed-loop circulation and cannot be in direct contact with the external environment, so that the cooling medium cannot be polluted and the normal operation of the shock absorber cooling system 1 cannot be influenced.

Further, as shown in fig. 4, the shock absorber module 20 further includes: the permanent magnet 26 and the second iron core 27, the permanent magnet 26 and the second iron core 27 are respectively arranged on the inner wall of the outer cylinder 232, a sealing piece 213 is arranged between the first iron core 21 and the permanent magnet 26, and/or a sealing piece 213 is arranged between the first iron core 21 and the second iron core 27.

Wherein the permanent magnet 26 and the second core 27 may also function to generate a magnetic field. The permanent magnet 26 and the second iron core 27 are respectively arranged on the inner wall of the outer cylinder 232, so that the permanent magnet 26 and the second iron core 27 can be fixed, the permanent magnet 26 and the second iron core 27 are more firmly and stably arranged, and the permanent magnet 26 and the second iron core 27 can work better.

The seal 213 mainly functions as a seal. Since an air gap exists between the first iron core 21 and the outer cylinder 232, the sealing member 213 is provided between the first iron core 21 and the permanent magnet 26, so that the air gap can be sealed, and the cooling medium is prevented from flowing out of the air gap. Alternatively, the sealing member 213 may be provided between the first core 21 and the second core 27, so that the air gap may be sealed to prevent the cooling medium from flowing out of the air gap. Of course, seals 213 may be provided between the first core 21 and the permanent magnet 26, and between the first core 21 and the second core 27, so that the air gap may be sealed better.

Further, as shown in fig. 1 and 2, the external cooling module 80 includes a liquid reservoir 10, and the liquid reservoir 10 communicates with the cooling medium inlet 28 and the cooling medium outlet 29, respectively. Wherein the reservoir 10 is mainly used for storing a cooling medium. The reservoir tank 10 is connected to the coolant inlet 28 and the coolant outlet 29, respectively, that is to say that the coolant in the reservoir tank 10 can enter the damper module 20 via the coolant inlet 28 and then flow back into the reservoir tank 10 via the coolant outlet 29.

It should be noted that, the shock absorber module 20 may be a linear motor, and the working principle of the linear motor is that in the prior art, the damping effect on the vehicle is achieved mainly by providing damping for the sliding of the guide rod 231 through the linear motor.

In addition, as shown in fig. 1 and 2, the damper cooling system 1 further includes a radiator 30, the radiator 30 being disposed between the cooling medium outlet 29 and the inlet of the reservoir 10. The radiator 30 mainly plays a role in heat dissipation and condensation, and the radiator 30 is arranged between the cooling medium outlet 29 and the inlet of the liquid storage tank 10, so that the cooling medium flowing out of the cooling medium outlet 29 can be cooled down and then introduced into the liquid storage tank 10 for storage.

In addition, as shown in fig. 1 and 2, the damper cooling system 1 further includes: a first check valve 40 and a second check valve 50, the first check valve 40 being disposed between the cooling medium outlet 29 and the inlet of the liquid reservoir 10 to allow the cooling medium to flow from the cooling medium outlet 29 toward the inlet of the liquid reservoir 10, and the second check valve 50 being disposed between the cooling medium inlet 28 and the outlet of the liquid reservoir 10 to allow the cooling medium to flow from the outlet of the liquid reservoir 10 toward the cooling medium inlet 28. Wherein, the first check valve 40 and the second check valve 50 can both play a role of unidirectional conduction.

The first check valve 40 is disposed between the cooling medium outlet 29 and the inlet of the liquid storage tank 10, so that the cooling medium flowing out from the cooling medium outlet 29 can only flow toward the inlet of the liquid storage tank 10, thereby avoiding the backflow of the cooling medium after heat exchange and affecting the cooling effect of the cooling medium. The second check valve 50 is disposed between the cooling medium inlet 28 and the outlet of the liquid storage tank 10, so that the cooling medium cooled by the radiator 30 in the liquid storage tank 10 can only flow from the outlet of the liquid storage tank 10 to the direction of the cooling medium inlet 28, and when the pressure in the liquid inlet cavity 24 increases, the cooling medium in the shock absorber module 20 can be prevented from flowing back to the liquid storage tank 10 from the inlet of the shock absorber module 20, the circulation of the cooling medium in the cooling flow path 211 is affected, and the cooling effect on the first iron core 21 and the coil 22 is further affected.

Specifically, when the guide rod 231 moves upward, the pressure in the liquid inlet cavity 24 increases, the cooling medium in the liquid inlet cavity 24 enters the cooling flow path 211 and the guide cavity 251 successively under the action of the pressure, and at the same time, the cooling medium exchanges heat with the first iron core 21 and the coil 22, so as to realize cooling of the first iron core 21 and the coil 22, and the cooling medium after heat exchange enters the radiator 30 for cooling and then is stored in the liquid storage tank 10, so that the cooling medium entering the liquid inlet cavity 24 can be always kept in a low-temperature state, and the cooling effect on the shock absorber module 20 can be kept.

As an alternative embodiment, as shown in fig. 2, the damper cooling system 1 further includes: a first throttle valve 60 and a second throttle valve 70, the first throttle valve 60 being provided at the cooling medium outlet 29, the second throttle valve 70 being provided at the cooling medium inlet 28. Wherein, the first throttle valve 60 and the second throttle valve 70 can both play a role of throttling, and the first throttle valve 60 is arranged at the cooling medium outlet 29, so that the first throttle valve 60 can control the flow of the cooling medium flowing out from the cooling medium outlet 29, thereby providing an additional damping force for the vehicle and additionally realizing a vibration reduction effect. Also, the second throttle valve 70 is provided at the cooling medium inlet 28, so that the second throttle valve 70 can control the flow rate of the cooling medium flowing into the cooling medium inlet 28, thereby providing an additional damping force to the vehicle, additionally realizing a vibration damping effect, and enabling the first throttle valve 60 and the second throttle valve 70 to be used in combination for more flexible use. In addition, the first throttle 60 and the second throttle 70 may also be integrated inside the shock absorber module 20.

It should be noted that the first throttle valve 60 and the second throttle valve 70 may be passive valves, i.e. a damping curve that is calibrated in advance may be provided to the first throttle valve 60 and the second throttle valve 70, where the damping effect of the first throttle valve 60 and the second throttle valve 70 is fixed, and where the damping effect of the first throttle valve 60 and the second throttle valve 70 is related to the speed of the relative movement between the mover assembly and the stator assembly. When the first and second throttles 60, 70 are passive, the first and second throttles 60, 70 provide the base damping force required by the shock absorber cooling system 1 and the shock absorber module 20 provides a low frequency damping force in part. In this way, the active and passive damping effect can be achieved by the first and second throttle valves 60 and 70, and cost, weight and space of the damper cooling system 1 can be saved instead of the conventional damper.

It should be noted that the first throttle 60 and the second throttle 70 may also be electrically controlled, i.e. an adjustable damping curve may be provided to the first throttle 60 and the second throttle 70, where the damping effect of the first throttle 60 and the second throttle 70 may be adjusted according to the actual requirement, and the damping effect of the first throttle 60 and the second throttle 70 is related to the speed of the relative movement between the mover assembly and the stator assembly. When the first and second throttles 60 and 70 are electrically controlled, the first and second throttles 60 and 70 provide the high frequency damping force required by the shock absorber cooling system 1 and the shock absorber module 20 provides in part the low frequency damping force. In this way, the active and passive damping effect can be achieved by the first and second throttle valves 60 and 70, and cost, weight and space of the damper cooling system 1 can be saved instead of the conventional damper.
