[0042] In view of the technical problem that the joint motor driver in the prior art has no heat dissipation structure and cannot adapt to the long-term and heavy-load operation requirements of the joint motor driver, the present invention provides a multifunctional housing back cover 1 of the joint motor driver, such as Figure 1 As shown, it is applied to the joint motor driver and fixed to one end of the housing 2 of the joint motor driver. The fixing method includes but is not limited to screws, rivets, buckles and other structures; Figure 2 As shown, the multifunctional housing back cover 1 comprises:
[0043] The heat dissipation structure 101 is arranged on a side of the multifunctional housing rear cover 1 facing the interior of the housing 2 , and is used to dissipate heat for electronic components in the housing 2 .
[0044] Specifically, the multifunctional housing back cover 1 and the heat dissipation structure 101 can be made of metal materials, such as aluminum alloy, which has good thermal conductivity, is easy to process, is light in weight, and is moderately priced. It can also be made of steel, steel-aluminum composite, cast iron, stainless steel, low-carbon steel, etc. Metal materials can enhance thermal conductivity, dissipate the heat generated by electronic components during operation in a timely manner, avoid overheating protection caused by excessive temperature in the joint motor driver, and meet the long-term and heavy-load operation requirements of the joint motor actuator.
[0045] As an optional implementation, Figure 2 As shown, the heat dissipation structure 101 includes:
[0046] A protrusion is arranged on the surface of the multifunctional housing rear cover 1, and a heat dissipation coating is arranged on the surface of the protrusion, and the heat dissipation coating is in contact with the electronic components.
[0047] The protrusions include:
[0048] A first protrusion 101A, wherein a heat dissipation coating on a surface of the first protrusion 101A contacts a power device in the electronic component;
[0049] The second protrusion 101B, the heat dissipation coating on the surface of the second protrusion 101B is in contact with the non-power device in the electronic component.
[0050] Specifically, Figure 2 As shown, the multifunctional housing back cover 1 includes a semicircular back cover area, the first protrusion 101A and the second protrusion 101B are arranged in the semicircular back cover area, and the first protrusion 101A and the second protrusion 101B can be integrally formed with the semicircular back cover area. The advantages of the one-piece molding process are: the one-piece molding process can integrate multiple processes into one operation, thereby greatly shortening the production cycle and improving production efficiency; the one-piece molding process can avoid the steps of processing multiple parts and assembling them in traditional processing, reducing production costs; during the one-piece molding process, heating and cooling treatments help to improve the hardness and strength of the aluminum alloy material, thereby improving the service life and quality of the product. The first protrusion 101A and the second protrusion 101B can simultaneously play the role of heat conduction and heat dissipation for power devices and non-power devices.
[0051] As an optional implementation, the heat-conducting material used for the heat-dissipating coating on the heat-dissipating structure 101 includes thermal grease or thermal silica gel. The heat-dissipating structure 101 needs to at least be in contact with the power device on the motor controller PCB (Printed Circuit Board). When the multifunctional housing back cover 1 is installed, a layer of thermal conductive material such as thermal grease can be applied between the heat-dissipating structure 101 and the power device.
[0052] As an optional implementation, Figure 4 As shown, the heat dissipation structure 101 includes:
[0053] A plurality of heat dissipation slots are arranged in parallel, and the heat dissipation slots are in contact with electronic components; the heat dissipation slots include a first heat dissipation slot 1011 and a second heat dissipation slot 1012, wherein the first heat dissipation slot is used to contact with power devices in the electronic components, and the second heat dissipation slot is used to contact with power devices and non-power devices in the electronic components. Figure 3 The basic back cover is shown in the figure. Figure 3 Heat dissipation grooves are provided on the semicircular rear cover area 10, and these heat dissipation grooves form passages between the interior of the housing and the external environment, which can better transfer the heat generated by the electronic components to the surrounding environment.
[0054] As an optional implementation, Figure 5 As shown, the heat dissipation structure 101 includes:
[0055] The water-cooled radiator includes a water inlet 1013, a water outlet 1014, and a water cooling pipe (omitted in the figure) for contacting the electronic components. Figure 3 The basic back cover is shown in the figure. Figure 3 A water-cooled radiator is provided on the semicircular rear cover area 10, and heat is exchanged through water-cooling pipes to help reduce the temperature, maintain normal operation and improve performance.
[0056] As an optional implementation, Figure 6 As shown, the heat dissipation structure 101 includes:
[0057] The air-cooled radiator includes a cooling fan 1015 and a plurality of rows of heat sinks 1016 arranged in parallel. Figure 3 The basic back cover is shown in the figure.

[0062] Specifically, the hollow structure 102 can be one or more. In this embodiment, multiple hollow structures 102 are designed. This is because the metal material of the multifunctional housing back cover will reduce the penetration of the WiFi signal. Therefore, the multifunctional housing back cover 1 is hollowed out to improve the penetration of the WiFi signal. In addition, the working status and communication status of the driver can be displayed through the joint status light display window 104 and the joint signal display window 105, which is convenient for later maintenance and repair;
[0063] As an optional implementation, Figure 2 As shown, the multifunctional housing back cover 1 also includes:

The capacitor explosion structure 103 can be one or more, and its number matches the number of capacitors. The capacitor explosion structure 103 can adopt a circular groove. In order to prevent the capacitor from exploding, a corresponding groove is set on the top of the capacitor housing, so that the top of the capacitor is easy to break first under high pressure, release the internal pressure, and improve the safety performance of the joint motor driver.
[0065] The present disclosure also provides a joint motor driver, such as Figure 1 As shown, it includes the multifunctional housing back cover 1 described in any one of the above embodiments.

The multifunctional housing back cover 1 may further include at least one capacitor explosion structure 103, which is arranged corresponding to the capacitor inside the housing 2. The capacitor explosion structure 103 may adopt a circular groove, so that the top of the capacitor is easy to rupture first under high pressure, release the internal pressure, and improve the safety performance of the joint motor driver.

The multifunctional housing back cover 1 may also include at least one capacitor explosion structure 103 and at least one capacitor explosion structure 103.
[0068] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved, and this document does not limit this.
