[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Combined with Figures 1-4 As shown, the embodiment of the present invention provides a wiring structure for wiring of the motor 1, including: a motor 1, a mounting bracket 2; a first contact 3, the first contact 3 is arranged on the motor 1, and the first contact 3 is electrically connected to the electrical device of the motor 1; a second contact 4, the second contact 4 is arranged on the mounting bracket 2, and the second contact 4 is electrically connected to the power supply device and / or the control device; the motor 1 is mounted on the mounting bracket 2, the first contact 3 is in contact with the second contact 4, and the power supply device and / or the control device supplies power to and / or transmits control signals to the motor 1 through the second contact 4 and the first contact 3.

[0032] This embodiment provides a motor wiring structure without wire routing. The electrical energy transmission is realized through the contact structure on the motor 1 and the mounting bracket 2, which can complete the connection of the motor power supply and the control circuit while the motor 1 is installed in place, saving the workload of installing the motor 1 and replacing the motor 1 after-sales, and improving the versatility of the motor 1. At the same time, it can also solve the problem that different wire lengths of the motor require more types of raw materials, which is not conducive to assembly.

[0033] Preferably, in order to ensure the contact stability of the contacts, the first contact 3 is a telescopic contact, and / or the second contact 4 is a telescopic contact. In the example provided in this embodiment, the first contact 3 is a telescopic contact, and the second contact 4 is a rigid contact.

[0034] Preferably, in order to ensure the assembly stability of the motor 1, the motor 1 is provided with at least one mounting foot 5. The mounting foot 5 is provided with bolt holes, and the motor 1 is fixed to the mounting bracket 2 through the bolt holes on the mounting foot 5. As the part of the motor 1 in direct contact with the mounting bracket 2, the first contact 3 is arranged on at least one mounting foot 5, and the second contact 4 is arranged on the mounting bracket 2 corresponding to at least one mounting foot 5. When the mounting foot 5 is bolted to the mounting bracket 2, the first contact 3 on the mounting foot 5 can be in electrical contact with the corresponding second contact 4 respectively.

[0035] Preferably, generally in order to ensure the assembly stability of the motor 1, there are at least two mounting feet 5. At this time, the first contacts 3 are respectively arranged on at least two mounting feet 5, and the second contacts 4 are respectively arranged on the mounting bracket 2 corresponding to at least two mounting feet 5. Theoretically, any number of first contacts 3 can be arranged on each mounting foot 5, which can be zero, multiple, or even all the first contacts 3 can be concentrated on a certain mounting foot 5.

[0036] Preferably, each contact needs to be connected to different electricities. In order to prevent incorrect connection of contacts during the assembly of the motor 1, resulting in the motor 1 not working or even burning out, the setting positions of the first contacts 3 on different mounting feet 5 are different, and the second contacts 4 are respectively arranged at different positions corresponding to the first contacts 3. Thus, when the assembly of the motor 1 is incorrect, due to the positioning of the mounting foot 5 through the bolt holes, the first contact 3 thereon does not match the second contact 4 that appears below at this time, and their positions are staggered and the two will not contact, thereby avoiding the safety hazard after the motor 1 is connected reversely.

[0037] Preferably, in this embodiment, when the first contact 3 is designed as a telescopic contact, the first contact 3 includes a first receiving cavity 6 recessed in the motor 1. A first terminal 7 is arranged in the first receiving cavity 6, and an elastic support 8 is also arranged in the first receiving cavity 6. The first terminal 7 extends or retracts through the elastic support 8. Specifically, the first receiving cavity 6 is arranged on the side of the mounting foot 5 facing the mounting bracket 2. In the initial state, under the action of the elastic support 8, the first terminal 7 extends outwards to the side. When the motor 1 is assembled to the mounting bracket 2, under the action of the bolt fastener, the mounting bracket 2 and the side of the mounting foot 5 are pressed against each other, and the first terminal 7 is pressed and contracts inwards against the elastic force of the elastic support 8.

[0038] Preferably, in order to ensure that the telescopic first terminal 7 can be stably electrically connected to the electrical device of the motor, a conductive inner lining 9 is arranged in the first receiving cavity 6. The first terminal 7 is telescopically arranged in the conductive inner lining 9 and remains in electrical contact with the conductive inner lining 9. The conductive inner lining 9 is electrically connected to the circuit of the motor 1 through a first conductive member 10.

[0039] Preferably, the housing of the motor 1 is made of a plastic encapsulation material, the conductive inner lining 9 is plastic encapsulated on the motor 1, and / or the first conductive member 10 is plastic encapsulated inside the motor 1. The housing of the motor 1 can be made of a thermosetting plastic, so as to facilitate the installation of conductive parts such as the first conductive member 10 and the conductive inner lining 9, and improve the production efficiency of the product.

[0040] Preferably, the second contact 4 includes a second receiving cavity 11 opened on the mounting bracket 2. A second terminal 12 is provided in the second receiving cavity 11. The second terminal 12 is electrically connected to the power supply device and / or the control device through a second conductive member 13. Since the mounting bracket 2 is usually made of a hard material such as metal, the second receiving cavity 11 can be a through hole penetrating the mounting bracket 2. The contact end of the second terminal 12 faces the side surface assembled with the mounting leg 5, and the other end is on the other side surface of the mounting bracket 2, and can be directly connected to the second conductive member 13. The second conductive member 13 can be a flexible cable. When the mounting bracket 2 can be made of a thermosetting plastic, the second conductive member 13 of the second contact 4 can also be in a concealed form plastic encapsulated inside the mounting bracket 2.

[0041] Preferably, when the mounting bracket 2 is also conductive, an insulating sheath 14 is sleeved outside the second terminal 12 for insulating the second terminal 12 from the mounting bracket 2.

[0042] Preferably, to ensure the electrical connection safety between the first contact 3 and the second contact 4, a sealing gasket 15 is provided between the motor 1 and the mounting bracket 2. The sealing gasket 15 is provided with contact holes corresponding to the positions of the first contact 3 and the second contact 4. The first contact 3 and the second contact 4 are in contact with each other in the contact holes, and the sealing gasket 15 can ensure the waterproof sealing between the first contact 3 and the second contact 4.

[0043] Preferably, to ensure the electrical connection safety between the first contact 3 and the second contact 4, the contact ends of the first contact 3 and the second contact 4 can be mutually matching concave-convex structures, such as a cross-shaped protrusion and a cross-shaped groove, etc. Any shape that can increase the contact conductivity between the two can be adopted.

[0044] The wiring structure of the embodiment of the present invention improves the lead structure of the motor into a power connection terminal structure at the contact part between the motor and the mounting bracket. The motor assembly does not require wire routing, reducing the workload of motor installation and after-sales motor replacement. The power connection terminals adopt single telescoping or double telescoping, and the two terminals have sufficient pre-tightening force to ensure stable contact conductivity.

[0045] A motor 1 adopts the above wiring structure.

[0046] A fan assembly adopts the above wiring structure.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and variations can still be made, and these improvements and variations should also be regarded as within the protection scope of the present invention.
