For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] As mentioned earlier, the heat dissipation module of backpack motors is usually stacked on top of the motor body. This type of backpack motor is easily limited by the height of the installation space, and when the height of the motor body is high, it will cause great inconvenience to the inspection and maintenance of the heat dissipation module.

[0031] In this embodiment of the utility model, the motor includes a motor body and a heat dissipation assembly. The side wall of the first housing of the motor body communicates with the side wall of the second housing of the heat dissipation assembly. The heat dissipation assembly includes a cooler located at least partially inside the second housing. The bottom of the first housing is provided with a plurality of first support members, and the bottom of the second housing is provided with a plurality of second support members. Furthermore, the bottom of the first housing and the bottom of the second housing are located on the same side of the motor, so that the bottom of the second housing is no longer stacked on top of the first housing, but is arranged in the same layer as the bottom of the first housing. That is, the heat dissipation assembly is no longer stacked on top of the motor, but is arranged in the same layer as the motor body along the side, so as to reduce the height of the heat dissipation assembly and the overall height of the motor, thereby facilitating the inspection and maintenance of the heat dissipation module and reducing the height limitation of the installation space on the motor, expanding the applicable scenarios of the motor.

[0032] The motor provided in this utility model example will be described below with reference to the accompanying drawings. It should be noted that the accompanying drawings of this utility model are only for the purpose of illustrative purposes and understanding of this embodiment, and are not intended to limit this utility model in any way, and are not necessarily drawn to scale.

[0033] like Figure 1-3As shown, this embodiment of the present invention provides a motor 100, including a motor body 110 and a heat dissipation assembly 120. The side wall of the first housing 111 of the motor body 110 communicates with the side wall of the second housing 121 of the heat dissipation assembly 120. The heat dissipation assembly 120 includes a cooler 122 located at least partially within the second housing 121. By configuring the side wall of the first housing 111 of the motor body 110 to communicate with the side wall of the second housing 121 of the heat dissipation assembly 120, hot airflow from the motor body 110 can enter the heat dissipation assembly 120, allowing the cooler 122 of the heat dissipation assembly 120 to cool the hot airflow generated by the motor body 110.

[0034] The motor body 110 may include components such as a stator, a rotor, and an output shaft 113, thereby driving the rotor to rotate the output shaft 113 through the magnetic field of the stator. The specific structure of the motor body 110 can be found in related technologies, and will not be described in detail here.

[0035] like Figure 2 As shown, in some optional embodiments, the cooler 122 includes an end cap 1221 and a heat exchange pipe 1222, with the end cap 1221 connected to the heat exchange pipe 1222. The heat exchange pipe 1222 is located inside the second housing 121, and the end cap 1221 is provided with a water inlet 1223 and a water outlet 1224 located outside the second housing 121, respectively communicating with the heat exchange pipe 1222. The cooler 122 may also include heat sinks connected to the heat exchange pipe 1222, and the number of heat exchange pipes 1222 and heat exchange sinks may be multiple to improve the heat absorption effect.

[0036] Cold water or other liquids can be injected into the heat exchange pipe 1222 as a coolant to absorb heat from the second housing 121. A channel for coolant flow in the heat exchange pipe 1222 can be constructed through the water inlet 1223 and water outlet 1224 of the end cap 1221, thereby removing the coolant that has risen in temperature from the heat exchange pipe 1222 and carrying away the heat from the second housing 121.

[0037] The cooler 122 includes an end cover 1221 and a heat exchange pipe 1222. The end cover 1221 is connected to the heat exchange pipe 1222, which is located inside the second housing 121. The end cover 1221 is provided with an inlet end 1223 and an outlet end 1224 located outside the second housing 121. The inlet end 1223 and the outlet end 1224 are respectively connected to the heat exchange pipe 1222. Cold water can be supplied to the heat exchange pipe 1222 inside the second housing 121 through the inlet end 1223 and the outlet end 1224 of the end cover 1221. After the hot airflow in the first housing 111 enters the second housing 121, the heat of the hot airflow can be transferred to the cold water flow through the heat exchange pipe 1222. The cold water flow carries away the heat of the hot airflow, thereby effectively cooling the airflow inside the motor 100.

[0038] like Figure 2 As shown, in some optional embodiments, the end cap 1221 can be located outside the second housing 121. The second housing 121 has an installation port, through which the heat exchange pipe 1222 passes and connects to the end cap 1221. The cooler 122 is detachably connected to the second housing 121 via the end cap 1221. For example, the end cap 1221 and the second housing 121 can have corresponding bolt holes, allowing the end cap 1221 to be detachably connected to the second housing 121 using bolts from the mounting bolt holes. In this embodiment, the end cap 1221 is located outside the second housing 121, facilitating the connection of the inlet end 1223 and the outlet end 1224 to an external liquid supply pipeline. The installation port on the second housing 121, through which the heat exchange pipe 1222 passes and connects to the end cap 1221, and the detachable connection of the cooler 122 to the second housing 121 facilitates disassembly of the cooler 122, thus enabling maintenance and repair of the cooler 122 by personnel.

[0039] like Figure 1As shown, the bottom of the first housing 111 is provided with a plurality of first support members 112, and the bottom of the second housing 121 is provided with a plurality of second support members 123. For example, when the outlines of the bottoms of the first housing 111 and the second housing 121 are approximately rectangular, a first support member 112 is provided at each of the four corners of the bottom of the first housing 111, and a second support member 123 is provided at each of the four corners of the bottom of the second housing 121. The bottoms of the first housing 111 and the second housing 121 are located on the same side of the motor 100, that is, the support members of the first housing 111 and the second housing 121 are located on one side of the motor 100. Through the first support members 112 and the second support members 123, the motor body 110 and the heat dissipation assembly 120 can be installed or fixed separately, which can reduce the load on the motor body 110 and reduce the connection between the motor body 110 and the heat dissipation assembly 120, thereby reducing the impact of vibration of the motor body 110 on the heat dissipation assembly 120.

[0040] In some optional embodiments, the first support member 112 is used to support between the first housing 111 and the ground, and the second support member 123 is used to support between the second housing 121 and the ground. This allows the motor body 110 and the heat dissipation assembly 120 to transfer their own weight to the ground through the first support member 112 and the second support member 123, respectively. This makes the first support member 112 and the second support member 123 mainly subjected to vertical pressure, reducing or eliminating the influence of lateral bending moment or additional torque on the first support member 112 and the second support member 123, and improving the stability of the first support member 112 and the second support member 123 in fixing the motor body 110 and the heat dissipation assembly 120.

[0041] like Figure 1 As shown, in some optional embodiments, the side of the first support member 112 away from the motor body 110 includes a first support plate 1121 with a first mounting hole 1122. The side of the second support member 123 away from the heat dissipation assembly 120 includes a second support plate 1231 with a second mounting hole 1232, and the second support plate 1231 is parallel to the first support plate 1121. The first support member 112 may also include a first support leg 1123 connected to the bottom of the first housing 111, and the first support plate 1121 is connected to the bottom of the first housing 111 via the first support leg 1123. The second support member 123 may also include a second support leg 1233 connected to the bottom of the second housing 121, and the second support plate 1231 is connected to the bottom of the second housing 121 via the second support leg 1233.

[0042] Optionally, the motor 100 itself may include fasteners such as bolts or expansion bolts, or additional fasteners such as bolts or expansion bolts may be configured during motor 100 installation. Based on the first mounting hole 1122 and the second mounting hole 1232, the fasteners included in the motor 100 or additionally configured fasteners can be used to fix the first support plate 1121 and the second support plate 1231 to the predetermined installation location of the motor 100, such as a predetermined position on the ground or wall, by passing through the first mounting hole 1122 and the second mounting hole 1232. This improves the stability of the motor 100 fixation by the first support member 112 and the second support member 123.

[0043] In this embodiment of the present invention, the motor 100 includes a motor body 110 and a heat dissipation assembly 120. The side wall of the first housing 111 of the motor body 110 communicates with the side wall of the second housing 121 of the heat dissipation assembly 120. The heat dissipation assembly 120 includes a cooler 122 located at least partially within the second housing 121. The bottom of the first housing 111 is provided with a plurality of first support members 112, and the bottom of the second housing 121 is provided with a plurality of second support members 123. Furthermore, the bottom of the first housing 111 and the bottom of the second housing 121 are located on the same side of the motor 100, so that the bottom of the second housing 121 is no longer stacked on top of the first housing 111, but is arranged in the same layer as the bottom of the first housing 111. That is, the heat dissipation assembly 120 is no longer stacked on top of the motor 100, but is arranged in the same layer as the motor body 110 in the lateral direction, thereby reducing the height of the heat dissipation assembly 120 and the overall height of the motor 100, thereby facilitating the inspection and maintenance of the heat dissipation module and reducing the height limitation of the installation space on the motor 100, and expanding the applicable scenarios of the motor 100.

[0044] like Figure 1-3 As shown, in some optional embodiments, the motor 100 further includes a fan and a heat exchange duct 140; the fan is disposed inside the first housing 111, and the side wall of the first housing 111 communicates with the side wall of the second housing 121 through the heat exchange duct 140.

[0045] The fan installed inside the first housing 111 promotes airflow circulation between the first housing 111 and the second housing 121, which facilitates the transfer of heat from the motor body 110 to the heat dissipation assembly 120 through airflow circulation. The heat exchange duct 140 allows for flexible arrangement of the airflow circulation channel, thereby improving the flexibility of gas circulation between the sidewalls of the first housing 111 and the second housing 121.

[0046] like Figure 3As shown, in some optional embodiments, there may be a certain gap between the sidewall of the first housing 111 and the sidewall of the second housing 121, thereby separating the sidewall of the first housing 111 of the motor body 110 and the sidewall of the second housing 121 of the heat dissipation assembly 120, so as to reduce the vibration transmitted from the motor body 110 to the heat dissipation assembly 120 through the first housing 111, and increase the heat dissipation area of ​​the first housing 111 and the second housing 121.

[0047] like Figure 2 As shown, in some optional embodiments, the heat exchange duct 140 includes a first heat exchange duct 141 and a second heat exchange duct 142, and the second housing 121 includes a first chamber 1211 and a second chamber 1212. The cooler 122 is located in the first chamber 1211. The first heat exchange duct 141 communicates with the first chamber 1211, and the second heat exchange duct 142 communicates with the second chamber 1212. The side of the first chamber 1211 away from the first heat exchange duct 141 communicates with the second chamber 1212, so that when the airflow flows between the first heat exchange duct 141 and the second chamber 1212, it needs to pass through the cooler 122. In this embodiment, the first chamber 1211 can limit the path of airflow within the second housing 121, so that the airflow contacts the cooler 122 as much as possible, preventing the airflow from bypassing the cooler 122, thereby fully utilizing the cooling effect of the cooler 122.

[0048] In some optional embodiments, the first heat exchange duct 141 is connected to the air outlet of the first housing 111, and the second heat exchange duct 142 is connected to the air inlet of the second housing 121. In this embodiment, after the hot airflow inside the motor body 110 is discharged from the first housing 111, it can enter the first chamber 1211 through the first heat exchange duct 141, so that the cooler 122 in the first chamber 1211 can handle the hottest airflow inside the second housing 121, thereby improving the utilization efficiency of the cooler 122.

[0049] like Figure 2 As shown, in some optional embodiments, the fan includes fan blades 131, which are connected to the output shaft 113 of the motor body 110. By connecting the fan blades 131 to the output shaft 113 of the motor 100, the output shaft 113 of the motor body 110 can directly drive the fan blades 131 to rotate, eliminating the need for a separate drive unit for the fan, thus reducing the cost and simplifying the fan's structure. Furthermore, a gap may exist between the mover and rotor of the motor body 110. The fan blades 131, mounted on the output shaft 113 of the motor body 110, can facilitate the flow of air within this gap, thereby more efficiently removing heat dissipated by the mover and rotor and improving the heat dissipation efficiency of the motor body 110.
