[0030] Combined with Figure 1 and Figure 2, an embodiment of the present utility model provides a driving and controlling integrated machine, including: a motor body 1 and a driver 2. A first electrical connection part is provided on the motor body 1, and a second electrical connection part is provided on the driver 2; the motor body 1 and the driver 2 are plugged through the first electrical connection part and the second electrical connection part to achieve electrical connection.

[0031] In this embodiment, the existing driving and controlling integrated machine is improved. The original motor body 1 and driver 2 are changed into two independent split modules. A first electrical connection part for connecting internal circuits is arranged on the plugging side of the motor body 1, and a second electrical connection part for connecting the internal control board 22 is arranged on the plugging side of the driver 2. When the control board 22 is a multi-layer board, the second electrical connection part is connected to the outermost layer of the multi-layer board. After the motor body 1 and the driver 2 are plugged through the first electrical connection part and the second electrical connection part, electrical connection between the motor body 1 and the driver 2 can be achieved. Based on this, the connection method between the motor body 1 and the driver 2 is improved from the traditional wire crimping to the plugging of electrical connection parts. The motor body 1 and the driver 2 can be assembled only by simple plugging, which has the advantages of convenient disassembly and assembly and simple maintenance, and also has advantages such as improving the motor protection performance, ensuring the motor operation efficiency and reducing costs.

[0032] Combined with Figure 3 and Figure 4 , in an embodiment, the first electrical connection part includes a plurality of conductive pins 11. One end of the conductive pin 11 is arranged outside the plugging side housing of the motor body 1, and the other end is arranged inside the plugging side housing; the second electrical connection part includes a plurality of conductive sockets 21, and one end of the plurality of conductive sockets 21 can be correspondingly connected to one end of the plurality of conductive pins 11.

[0033] In this embodiment, the plurality of conductive pins 11 can be correspondingly connected to a plurality of motor phase lines in the motor body 1 one by one. The specific number of the conductive pins 11 depends on the type of the motor. One end of the conductive pin 11 is used as a plug and penetrates outside the plugging side of the motor body 1, and the other end of the conductive pin 11 is arranged inside the plugging side housing and is connected to the corresponding motor phase line inside the motor body 1.

[0034] In this embodiment, the number of the conductive sockets 21 corresponds to the number of the conductive pins 11 one by one. The conductive sockets 21 are arranged on the control board 22 inside the driver 2. One end of the conductive socket 21 exposes the surface of the plugging side of the driver 2 and is provided with a plugging hole for the conductive pin 11 to insert.

[0035] In this embodiment, by plugging the plugging sides of the motor body 1 and the driver 2 into each other, the plurality of conductive pins 11 are inserted into the plugging holes of the plurality of conductive sockets 21 one by one, so that the assembly of electrical connection between the motor body 1 and the driver 2 can be completed, and the whole process is very simple and convenient.

[0036] In this embodiment, both the conductive needle 11 and the conductive socket 21 can be made of a metal material with good electrical conductivity and corrosion resistance, so as to ensure the quality of electrical transmission.

[0037] Combined Figure 5 As shown, in one embodiment, the first electrical connection portion further includes a bracket 12. A plurality of brackets 12 are arranged on the insertion side of the motor body 1, and a plurality of conductive needles 11 are fixed in the plurality of brackets 12.

[0038] In this embodiment, to ensure the connection stability between the first electrical connection portion and the second connection portion, a plurality of brackets 12 are arranged on the insertion side of the motor body 1. The number of brackets 12 is the same as the number of conductive needles 11, and the plurality of conductive needles 11 are fixed one by one by the plurality of brackets 12.

[0039] In a specific embodiment of the bracket 12.

[0040] An installation hole is formed on the insertion side of the motor body 1. The bracket 12 includes an internally and externally self-locking expansion sleeve 121. The conductive needle 11 is limited inside the expansion sleeve 121, and the outer wall of the expansion sleeve 121 fits with the installation hole. Specifically, a first limiting portion 122 and a second limiting portion 123 are provided on the inner wall of one end of the expansion sleeve 121, and the expansion sleeve 121 is provided with an expansion opening; a raised ring 111 is provided on the outer wall of the conductive needle 11.

[0041] In this specific embodiment, the structure design of the internally and externally self-locking expansion sleeve 121 is as follows: the expansion sleeve 121 can be made of a plastic part and has a spring-back performance when stressed; raised external buckles are provided at both axial ends of the expansion sleeve 121, and the first limiting portion 122 and the second limiting portion 123 are arranged at intervals in the inner wall of the expansion sleeve 121, and an expansion opening is formed along the axial direction on the barrel body of the expansion sleeve 121.

[0042] Based on the structural design of the expansion sleeve 121 in this embodiment, the specific working process is as follows: First, one end of the conductive needle 11 is inserted into the other end of the expansion sleeve 121. During the insertion process, the raised ring 111 on the outer wall of the conductive needle 11 will squeeze the second limiting portion 123 on the inner wall of the expansion sleeve 121, causing the expansion opening of the expansion sleeve 121 to be pushed open. At this time, the second limiting portion 123 is also lifted until the raised ring 111 on the outer wall of the conductive needle 11 completely passes through the second limiting portion 123. At this time, the expansion opening and the second limiting portion 123 return to normal, and the raised ring 111 on the outer wall of the conductive needle 11 engages with the first limiting portion 122 and the second limiting portion 123. Then, the other end of the expansion sleeve 121 is inserted into the mounting hole. During the insertion process, the mounting hole will squeeze the expansion opening, causing the outer diameter of the other end of the expansion sleeve 121 to slightly contract, facilitating the smooth passage of the expansion sleeve 121 through the mounting hole. Finally, after the expansion sleeve 121 passes through the mounting hole, the outer buckles protruding from both ends of the expansion sleeve 121 are buckled on both ends of the mounting hole, which can ensure that the expansion sleeve 121 is stably installed on the insertion side of the motor body 1. At this time, the expansion sleeve 121 is fixed in the mounting hole and cannot be squeezed and expanded, thereby ensuring that the raised ring 111 on the outer wall of the conductive needle 11 can be stably arranged between the first limiting portion 122 and the second limiting portion 123. Based on this, the bracket 12 realizes stable limiting of the conductive needle 11 to ensure that the conductive needle 11 can be stably inserted into the conductive socket 21.

[0043] In another specific embodiment of the bracket 12.

[0044] Combined Figure 6 As shown, the bracket 12 includes an outer buckle sleeve 124 and an inner threaded sleeve 125. The outer wall of the outer buckle sleeve 124 is buckled on the mounting hole, and the outer wall of the inner threaded sleeve 125 is threadedly connected to the inside of the outer buckle sleeve 124 to form a limiting space inside the outer buckle sleeve 124, and the conductive needle 11 is fixed in the limiting space. Specifically, the inner wall of the outer buckle sleeve 124 is provided with a third limiting portion 126, a limiting space is formed between the end face of one end of the inner threaded sleeve 125 and the third limiting portion 126, and the outer wall of the conductive needle 11 is provided with a raised ring 111.

[0045] In this specific embodiment, the outer buckle sleeve 124 can be made of a plastic part adapted to the size of the mounting hole. The outer buckle sleeve 124 is provided with raised outer buckles at both ends in the axial direction. The inner wall of one end of the outer buckle sleeve 124 is provided with a third limiting portion 126, and the inner wall of the other end of the outer buckle sleeve 124 is provided with an internal thread. The outer wall of one end of the inner threaded sleeve 125 is provided with an external thread, and the inner threaded sleeve 125 is threadedly connected to the inside of the outer buckle sleeve 124, so that a limiting space is formed between the end face of one end of the inner threaded sleeve 125 and the third limiting portion 126.

[0046] The specific working process is as follows: First, one end of the conductive pin 11 is inserted into the other end of the outer snap sleeve 124. During the insertion process, the raised ring 111 on the outer wall of the conductive pin 11 can abut against the third limiting portion 126 of the outer snap sleeve 124. Then, one end of the internal thread sleeve 125 is first sleeved on the other end of the conductive pin 11, and then the outer wall thread of the internal thread sleeve 125 is threadedly connected to the inner wall of the other end of the outer snap sleeve 124 until the end face of one end of the internal thread sleeve 125 abuts against the raised ring 111 on the outer wall of the conductive pin 11, so that the raised ring 111 of the conductive pin 11 can be fixed in the limiting space. Finally, the outer snap sleeve 124 is installed in the installation hole, and the outer wall of the outer snap sleeve 124 is snapped into the installation hole to complete. Based on this, the stable limiting of the conductive pin 11 is realized through the bracket 12 to ensure that the conductive pin 11 can be stably inserted into the conductive socket 21.

[0047] In one embodiment, the conductive socket 21 is electrically connected to the control board 22 inside the driver 2 by at least one of welding and / or metal fixed connection.

[0048] In this embodiment, to ensure the stability of the conductive socket 21 on the insertion side of the driver 2, it is preferably to electrically connect the conductive socket 21 to the control board 22 inside the driver 2 by welding. The welding method is more stable and the position will not loosen, which can ensure the alignment accuracy between the conductive socket 21 and the corresponding conductive pin 11.

[0049] Combined Figure 2 As shown, in one embodiment, the drive and control integrated machine further includes a fixing member 3; the insertion sides of the motor body 1 and the driver 2 are mutually engaged, and the motor body 1 and the driver 2 are mutually fixed by a plurality of fixing members 3.

[0050] In this embodiment, the shapes of the insertion sides of the motor body 1 and the driver 2 can be adaptively designed. For example, the insertion side of the motor body 1 protrudes, and the insertion side of the driver 2 is concave. By the mutual engagement of the insertion sides of the motor body 1 and the driver 2, it is easier for the two to be aligned and inserted and more stable after insertion, and after being mutually fixed by a plurality of fixing members 3, the assembly can be completed, further ensuring the stability of the motor body 1 and the driver 2 after insertion.

[0051] In one embodiment, the drive and control integrated machine further includes a motor housing 13 and a driver housing 23; the motor housing 13 covers all components inside the entire motor body 1, and the driver housing 23 covers all components inside the entire driver 2; the fixing member 3 is used to penetrate the motor housing 13 and the driver housing 23 and be fixed.

[0052] In this embodiment, both the motor body 1 and the driver 2 adopt independent casings. The plug-in sides of the motor body 1 and the driver 2 are the openings of their respective casings. After the plug-in sides of the motor body 1 and the driver 2 are plugged into each other, the motor casing 13 and the driver casing 23 just completely fit and seal, so as to protect the plug-in position.

[0053] In this embodiment, the fixing member 3 may include screws. A plurality of corresponding connection holes can be provided on the motor casing 13 and the driver casing 23. The motor casing 13 and the driver casing 23 are fixedly connected by threading a plurality of screws through the connection holes on the motor casing 13 and the driver casing 23 one by one, so as to ensure the stable connection between the motor body 1 and the driver 2.

[0054] The drive and control integrated machine described above. In this solution, the motor body 1 and the driver 2 are each made into an independent module. The wire-slinging scheme of the motor is changed to a fixed socket type scheme (similar to a plug), and the driver 2 is also an independent module (similar to a socket). The assembly of the two modules only needs to be simply completed by the plug-in method of inserting the plug into the socket, and then several screws are tightened. If the two modules need to be maintained later, the disassembly is also simple; and in the modular scheme, the motor manufacturer and the system integrator each undertake their own good fields. No matter which party completes the combination of the later products, it is very convenient. When the system integrator molds its own module, only the plug-in holes for connection need to be reserved. One motor body 1 can be compatible with the customization requirements of different system integrators, providing more options for product expansion.

[0055] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
