DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0024] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, the controller 100 of the vehicle of the embodiment of the utility model includes a first shell 1, a second shell 2 and a circuit board 3. The first shell 1 is connected to the second shell 2 and defines an installation space. The first shell 1 is a heat-conducting shell and is used to be connected to the vehicle body 200. The circuit board 3 is arranged in the installation space and transfers heat to the first shell 1.

[0026] When the controller 100 of the vehicle of the embodiment of the utility model is installed, the first housing 1 is connected to the vehicle body 200 by fasteners or welding. When the controller 100 is working, the heat generated by the circuit board 3 during the working process can be transferred to the first housing 1 by heat convection or heat conduction. Since the first housing 1 is a heat-conducting housing, the first housing 1 will transfer the heat generated by the circuit board 3 to the vehicle body 200, and the vehicle body 200 with a sufficiently large heat dissipation area will perform convection heat exchange and radiation heat exchange with the air, thereby achieving heat dissipation of the controller 100.

[0027] Therefore, the controller 100 of the vehicle in the embodiment of the utility model sets its own shell as a heat-conducting shell, which directly transfers heat to the vehicle body 200 for heat dissipation. Therefore, the size of the heat dissipation fins on the controller 100 can be reduced, or even the setting of the heat dissipation fins can be cancelled, which not only saves the material usage of the heat dissipation fins, reduces the weight and manufacturing cost, but also reduces the overall size of the controller 100, reduces the space occupied by the controller 100, and makes assembly simpler and more convenient.

[0028] In some embodiments, the first housing 1 has an inner bottom wall 101 and an outer bottom wall 102 opposite to each other, and the inner bottom wall 101 is provided with a heat dissipation boss 4. The circuit board 3 includes an electrical component 301, and on a projection plane orthogonal to the bottom wall of the first housing 1, the projection of the electrical component 301 at least partially overlaps with the projection of the heat dissipation boss 4, and the outer bottom wall 102 is used to be connected to the vehicle body 200.

[0029] like Figure 4 and Figure 5As shown, the inner bottom wall 101 is located inside the controller 100, and the inner bottom wall 101 is provided with heat dissipation bosses 4, which are used to increase the heat dissipation area between the inner bottom wall 101 and the electrical component 301, thereby enhancing the heat conduction efficiency, so that the heat generated by the electrical component 301 can be more easily conducted from the electrical component 301 to the outside of the controller 100. The outer bottom wall 102 is used to connect with the vehicle body 200, ensuring the stable installation of the controller 100, and also plays a role in heat conduction, so that the heat can be effectively transferred from the controller 100 to the vehicle body 200. The arrangement of the inner bottom wall 101 and the outer bottom wall 102 makes the structure of the controller 100 more reasonable, which can not only meet the heat dissipation requirements, but also ensure stable installation and good heat conduction.

[0030] In some embodiments, the heat dissipation boss 4 is welded to the inner bottom wall 101 , and the thermal conductivity of the heat dissipation boss 4 is greater than the thermal conductivity of the first shell 1 .

[0031] The heat dissipation boss 4 is connected to the inner bottom wall 101 by welding, which can ensure a firm connection between the two and prevent loosening or separation during use, thereby ensuring effective heat conduction. It can be understood that thermal conductivity is an important indicator for measuring the thermal conductivity of a material. The higher the value, the better the thermal conductivity of the material. Therefore, the high thermal conductivity of the heat dissipation boss 4 enables it to quickly transfer the heat inside the controller 100 from the electrical component 301 to the housing, and then transfer it to the vehicle body 200 through the housing, so that the controller 100 is maintained at a lower temperature, ensuring its stability and reliability in high temperature environments.

[0032] Optionally, the heat dissipation boss 4 is made of a metal material with high thermal conductivity, such as copper or aluminum.

[0033] In some embodiments, the first housing 1 has a first side wall 103, the second housing 2 has a second side wall 201, the first side wall 103 is parallel to the second side wall 201 and is located on the same side. The first side wall 103 is provided with an insertion port 1031, the second side wall 201 is provided with a water retaining plate 5 located outside the second housing 2, and the water retaining plate 5 extends along the thickness direction of the second side wall 201.

[0034] like Figure 3 As shown, the plug port 1031 on the first side wall 103 is used to connect other components or transmit data, making the connection and data transmission more convenient. The water baffle 5 extends along the thickness direction of the second side wall 201, and its function is to prevent water vapor or other liquids from entering the interior of the controller 100 and protect the safety of the electrical components 301.

[0035] In some embodiments, the controller 100 of the vehicle of the utility model embodiment also includes an elastic heat conductive sheet 6, which has a first surface and a second surface 601 opposite to each other along its thickness direction. The first surface is attached to the outer bottom wall 102, and the second surface 601 is used to be attached to the vehicle body 200.

[0036] like Figure 5 and Figure 6 As shown, in the actual manufacturing and assembly process, there will always be certain assembly tolerances due to factors such as material properties, processing accuracy, and temperature changes. These tolerances may cause the gap between the controller 100 and the vehicle body 200 to be uneven, affecting the heat conduction efficiency. The elastic heat conductive sheet 6 has the ability to adapt to assembly tolerances. Due to its own elasticity, it can fill the irregular gap between the controller 100 and the vehicle body 200, ensuring good contact between the two, making the connection between the controller 100 and the vehicle body 200 more reliable, and reducing the risk of failure due to assembly tolerances.

[0037] Optionally, the first surface of the elastic heat conductive sheet 6 is connected to the outer bottom wall 102 by bonding. By using an adhesive to connect the first surface of the elastic heat conductive sheet 6 to the outer bottom wall 102, a firm connection can be formed to prevent loosening or separation during use. This connection method is simple and reliable and is applicable to different material surfaces. The bonding method can ensure that the contact between the elastic heat conductive sheet 6 and the outer bottom wall 102 is closer, reduce heat loss during conduction, and improve heat conduction efficiency.

[0038] Optionally, adhesive is provided on the second surface 601. The adhesive property of the adhesive can enable the elastic heat conductive sheet 6 to automatically fill the small gap between the controller 100 and the vehicle body 200 during the assembly process, absorb the uneven gap caused by the assembly tolerance, make the contact between the elastic heat conductive sheet 6 and the vehicle body 200 closer, ensure the continuity and uniformity of heat conduction, and thus improve the heat conduction efficiency.

[0039] In some embodiments, the outer surface of the elastic thermally conductive sheet 6 is covered with a graphene film.

[0040] It is understandable that the graphene film is a material composed of a single layer of carbon atoms, and has the characteristics of high thermal conductivity, high electrical conductivity, etc. The graphene film is covered on the surface of the elastic thermal conductive sheet 6. The high thermal conductivity of the graphene film can quickly transfer heat from the electrical component 301 to the elastic thermal conductive sheet 6, and then transfer it to the vehicle body 200 through the elastic thermal conductive sheet 6, which can further enhance the thermal conductivity of the elastic thermal conductive sheet 6 and improve the heat dissipation efficiency of the controller 100.

[0042] In some embodiments, the first housing 1 is integrally formed with the vehicle body 200.

At this time, a protective coating needs to be sprayed on the circuit board 3 to protect the circuit board 3.
