[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0028] Example 1: Please refer to Figures 1 to 7 The present invention provides a motor combined heat dissipation device, comprising a heat dissipation housing, a drive board 11 disposed in the heat dissipation housing, a stator and a rotor mounted in the heat dissipation housing and connected to the drive board 11 via a cable, a first heat dissipation assembly 12 mounted on the drive board 11, the heat dissipation housing comprising a first housing 1, a second housing 2, and a third housing 3, the first housing 1, the second housing 2, and the third housing 3 being fixed together by a connector, the drive board 11 and the first heat dissipation assembly 12 being mounted in the third housing 3, and the stator and the rotor being mounted in the second housing 2; an isolation support 4 being disposed between the third housing 3 and the second housing 2, the isolation support 4 being used to block heat from within the second housing 2; a placement position being disposed within the interior of the third housing 3 away from the second housing 2, the drive board 11 and the first heat dissipation assembly 12 being mounted on the placement position, the first heat dissipation assembly 12 being closely attached to the third housing 3. The third housing 3 is used to enclose the second housing 2; an isolation support 4 being disposed between the third housing 3 and the second housing 2, the isolation support 4 being used to block heat from within the second housing 2.

[0029] The device of this embodiment is designed with a first shell 1, a second shell 2, a third shell 3 and an isolation support 4. When the stator and rotor in the second shell 2 are in motion, a large amount of heat is generated. The isolation support 4 can effectively block the heat in the second shell 2, and at this time, it rarely affects the drive board 11 in the third shell 3. At the same time, the first shell 1, the second shell 2 and the third shell 3 themselves are made of heat dissipation materials, so that effective heat dissipation can be achieved.

[0030] The driving board 11 includes a PCB power driving board and electronic components mounted on the PCB power driving board. The third housing 3 is designed mainly to dissipate heat from the PCB power driving board.

[0031] The isolation support member 4 includes a support plate 9, a rotor hole base for mounting the rotor on the support plate 9, a wire hole 7 provided on the support plate 9, a bidirectional sealed terminal block mounted on the wire hole 7, and at least one reinforcing rib 8 mounted on the support plate 9. Seals, in the form of sealing rings 13, are provided between the support plate 9 of the isolation support member 4 and both surfaces of the third and second housings 3 and 2.

[0032] In this embodiment, the stator and the rotor are connected to the drive board 11 through cables. The original design generally provides a wire hole 7 on the support plate 9. The design of the original wire hole 7 will have a new problem. The heat from the second shell 2 will pass through the gap between the cable and the wire hole 7 to the third shell 3, causing additional or even destructive temperature rise on the drive board, resulting in damage to the electronic components of the drive board. In this case, a bidirectional sealed terminal block is designed to effectively seal and prevent heat from passing through the gap between the cable and the wire hole 7, so that the heat blocking effect will be stronger.

[0033] The outer ring of the isolation support member 4 and the outer surface of the heat dissipation housing are both provided with heat dissipation ribs 6, and the number of heat dissipation ribs 6 is at least one. The support plate 9 is made of a hard material, and its inner and outer surfaces are additionally provided with a heat insulation material, which is a heat insulation board, a heat insulation pad, or a heat insulation coating.

[0034] In this embodiment, both sides of the support plate 9 of the isolation support member 4 are made of insulation material, which can be an insulation board, insulation pad or insulation paint, etc. The design of the heat dissipation ribs 6 can avoid the situation of being hot when touching the heat dissipation shell.

[0035] The second shell 2 is provided with two supporting legs 5. The first shell 1, the second shell 2 and the third shell 3 are made of heat dissipation materials. The support plate 9 is made of hard material, and its inner and outer surfaces are additionally provided with heat insulation materials.

[0036] The third housing 3 is provided with a placement position inside away from the second housing 2, and the driver board 11 and the first heat dissipation component 12 are both installed in the placement position, with the first heat dissipation component 12 being closely attached to the third housing 3. In this embodiment, the third housing 3 is provided with a placement position inside away from the second housing 2, and the first heat dissipation component 12 is installed in the placement position. This design distance is further away, again preventing the heat in the second housing 2 from affecting the driver board 11; at the same time, the driver board 11 can transfer a large amount of heat from the driver board 11 to the third housing 3 through the first heat dissipation component 12, so that heat can also be dissipated through the third housing 3. The material of the first heat dissipation component 12 is a thermally conductive material, and the shape of the first heat dissipation component 12 can be square, rectangular, circular, or other shapes suitable for installation, etc. There is at least one first heat dissipation component 12. The driver board 11 is a driver board or other electronic component.

[0037] A second heat sink assembly is mounted on the third housing 3. The second heat sink assembly includes a heat conducting plate 10 mounted on the third housing. The heat conducting plate 10 is provided with heat dissipation ribs 6. The heat conducting plate 10 can be square, circular, or any other suitable shape, and its size can be large or small according to actual needs.

[0038] In this embodiment, the first heat dissipation component 12 can be effectively dissipated by the heat conducting plate 10. The material of the heat conducting plate 10 is a heat conductive material. A connecting device is provided on the heat conducting plate 10. The connecting device can be tightly connected to the third shell 3, and the heat dissipation area is additionally increased. In this way, the heat in the third shell 3 can be better guided to the heat conducting plate, so that the driving board 11 can be dissipated for a second time, and the heat dissipation effect is better.

[0039] The circuits and controls involved in this utility model are all prior art and will not be described in detail here. The above are only embodiments of this utility model and do not limit the scope of the patent of this utility model. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of this utility model, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this utility model.
