[0002] Electromagnetic shock absorber (also known as electromagnetic shock absorber) is an advanced shock absorption system that uses electromagnetic reaction to adjust the damping force. It is mainly used in high-end vehicles to improve driving stability and comfort. It changes the current intensity in the electromagnetic coil and adjusts the viscosity of the magnetorheological fluid inside the shock absorber in real time, thereby achieving rapid adaptation to road vibration response.

[0003] For example, in the prior art, the patent with the patent authorization announcement number CN211778703U discloses an electromagnetic damping shock absorber, including a piston, a piston rod, an iron core, a winding and an excitation winding; the iron core includes an outer iron core and an inner iron core, the outer iron core is hollow, the inner iron core is located inside the outer iron core, the piston is connected to the piston rod, the piston and the piston rod are provided with communicating sliding holes, and the inner iron core extends into the sliding hole; the outer diameter of the piston matches the inner diameter of the outer iron core; the lower part of the inner iron core is wound with an excitation winding; the outer part of the piston rod is wound with a winding winding. This electromagnetic damping shock absorber generates a magnetic field by winding an excitation winding at the lower part of the inner iron core and energizing the excitation winding; the winding winding cuts the magnetic field as the piston rod moves up and down, thereby converting the vibration energy of the shock absorber into electrical energy, and the converted electrical energy can power the excitation winding on the one hand, and power other electrical facilities in the vehicle on the other hand, thereby realizing energy recycling.

[0004] Although the electromagnetic damper in the above patent realizes energy recycling, the electromagnetic coil of the electromagnetic damper generates heat when working. If the heat cannot be processed in time, it will cause local overheating of the barrel, thereby accelerating material aging or causing deformation, and further affecting the structural strength of the barrel.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electromagnetic shock absorber with a single rod, double tubes and double coils, comprising a shock absorber body, the outer wall of which is connected to a symmetrically arranged heat dissipation component, a plurality of ventilation slots are opened on the heat dissipation component, and the ventilation slots are evenly distributed. A heat dissipation fan is connected to the bottom of the heat dissipation component, and the air outlet of the heat dissipation fan is connected to the lower end of the ventilation slot.

[0007] Furthermore, the heat dissipation assembly includes two symmetrically arranged heat dissipation shells and threaded rings, the outer wall of the upper end of the heat dissipation shell is provided with an upper end threaded groove, the threaded ring is threadedly connected to the upper end threaded groove, and the inner wall of the heat dissipation shell is against the outer wall of the shock absorber body.

[0011] Furthermore, a filter is fixedly connected to the air inlet position at the lower end of the heat dissipation fan.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] When this type of single-rod, double-tube, double-coil electromagnetic shock absorber is working, the heat dissipation component will export the heat inside the shock absorber body. At the same time, the heat dissipation fan will blow external cold air into the ventilation slots of the heat dissipation component, and the heat exported by the heat dissipation component will be taken away by the cold air, thereby achieving the effect of lowering the temperature and avoiding local overheating of the shock absorber body.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-4 A single-rod, double-tube, double-coil electromagnetic shock absorber comprises a shock absorber body 1. The outer wall of the shock absorber body 1 is connected to a symmetrically arranged heat dissipation component. A plurality of ventilation slots 3 are opened on the heat dissipation component. The ventilation slots 3 are evenly distributed. A heat dissipation fan 4 is connected to the bottom of the heat dissipation component. The air outlet of the heat dissipation fan 4 is connected to the lower end of the ventilation slot 3.

[0021] In the utility model, the electromagnetic shock absorber with a single rod, double barrels and double coils, when working, the heat dissipation component will export the heat inside the shock absorber body 1, and at the same time, the heat dissipation fan 4 will blow the external cold air into the ventilation slots 3 of the heat dissipation component, and the heat exported by the heat dissipation component will be taken away by the cold air, thereby achieving the effect of lowering the temperature and avoiding the phenomenon of local overheating of the shock absorber body 1. In addition, the heat dissipation fan 4 is an existing mature product, and the structure of the shock absorber body 1 is similar to the prior art, and the electromagnetic damping shock absorber structure disclosed in the patent with patent authorization announcement number CN211778703U, so no further elaboration will be made here. The power supply of the heat dissipation fan 4 can come from the power supply of the electromagnetic shock absorber with a single rod, double barrels and double coils, or it can have its own power supply.

[0022] like Figures 1 to 4 As shown, the heat dissipation assembly includes two symmetrically arranged heat dissipation shells 2 and threaded rings 9. The outer wall of the upper end of the heat dissipation shell 2 is provided with an upper threaded groove 7. The threaded ring 9 is threadedly connected to the upper threaded groove 7. The inner wall of the heat dissipation shell 2 is against the outer wall of the shock absorber body 1.

[0023] like Figure 3 and Figure 4 As shown, an air guide block 5 is fixed to the bottom of the shock absorber body 1, the bottom of the heat dissipation shell 2 is abutted against the edge of the top of the air guide block 5, the outer wall of the lower end of the heat dissipation shell 2 is provided with a lower end thread groove 8, and the heat dissipation fan 4 is threadedly connected to the lower end thread groove 8.

[0024] Specifically, when it is necessary to clean the ventilation grooves 3 inside the heat dissipation shell 2, the threaded ring 9 can be removed first, and then the heat dissipation fan 4 can be rotated to separate the heat dissipation fan 4 from the heat dissipation shell 2. Then the heat dissipation shell 2 can be unfolded to both sides of the shock absorber body 1, which is convenient for cleaning the ventilation grooves 3 inside the heat dissipation shell 2. During installation, it is only necessary to place the heat dissipation shell 2 on both sides of the shock absorber body 1, and let the bottom of the heat dissipation shell 2 abut against the top of the air guide block 5, and then rotate the heat dissipation fan 4 to make the heat dissipation fan 4 threadedly connected to the lower end threaded groove 8, and finally the threaded ring 9 is threadedly connected to the upper end threaded groove 7 of the heat dissipation shell 2. The operation process is simple and convenient.

[0025] like Figure 4 As shown, the air guide block 5 is in the shape of an inverted cone as a whole. The air guide block 5 of this shape can guide the cold air blown out by the heat dissipation fan 4, so that the cold air can enter the ventilation slot 3 conveniently.

[0026] like Figures 1 to 4 As shown, a plurality of toggle blocks 10 are fixedly connected to the outer wall of the threaded ring 9, and the toggle blocks 10 are evenly distributed.

[0027] Specifically, the toggle block 10 increases the surface area of ​​the threaded ring 9 , making it easier for an operator to grip the threaded ring 9 and to rotate the threaded ring 9 .

[0028] like Figure 2 and Figure 4 As shown, a filter screen 6 is fixedly connected to the air inlet position at the lower end of the heat dissipation fan 4. The filter screen 6 is used to simply filter the air entering the ventilation slot 3 to reduce the probability of dust entering the ventilation slot 3.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
