[0034] See also Figures 1 to 7 The embodiment of the utility model provides a PCB board 2 and a motor adapter 1, which is used to connect the PCB board 2 and the driving motor 3, and includes: a base 10; a first card pin 11 and a second card pin 12 provided on the base 10, the first card pin 11 and the second card pin 12 respectively corresponding to the positive pin and the negative pin of the driving motor 3; a first PCB connector 13 and a second PCB connector 14 provided on the base 10, the first PCB connector 13 and the second PCB connector 14 are used to connect the PCB board 2, and the first PCB connector 13 is electrically connected to the first card pin 11 in the base 10, and the second PCB connector 14 is electrically connected to the second card pin 12 in the base 10.

[0035] The adapter device 1 in this embodiment integrates the first card pin 11 and the second card pin 12 connected to the drive motor 3 and the first PCB connector 13 and the second PCB connector 14 connected to the PCB board 2 into a whole through the base 10, which reduces the influence of the first card pin 11, the second card pin 12, the first PCB connector 13 and the second PCB connector 14 on the external environment, making the connection between the PCB board 2 and the drive motor 3 more stable. It should be explained that the PCB board 2 is provided with slots corresponding to the first PCB connector 13 and the second PCB connector 14, and the first PCB connector 13 and the second PCB connector 14 are inserted into the slots provided on the PCB board 2. Optionally, the first PCB connector 13 and the second PCB connector 14 are welded to the PCB board 2. In one embodiment, the first PCB connector 13 and the second PCB connector 14 are inserted into the slots provided on the PCB board 2, and the first PCB connector 13 and the second PCB connector 14 are also welded to the PCB board 2.

[0036] Optionally, the first card pin 11, the second card pin 12, the first PCB connector 13, and the second PCB connector 14 are all hardware. Figure 6, the first PCB connector 13 is electrically connected to the first card pin 11 through hardware, and the second PCB connector 14 is electrically connected to the second card pin 12 through hardware. Preferably, the first PCB connector 13 and the first card pin 11 are an integrated structure, and the second PCB connector 14 and the second card pin 12 are an integrated structure. Optionally, the first PCB connector 13 and the second PCB connector 14 are symmetrically arranged on the base 10. Optionally, the first card pin 11 and the second card pin 12 are symmetrically arranged on the base 10. Optionally, the adapter 1 is a left-right symmetrical structure, that is, the base 10 has a symmetry line that divides it into left and right halves, the first card pin 11 and the first PCB connector 13 are arranged on one side of the symmetry line, and the second card pin 12 and the second PCB connector 14 are arranged on the other side of the symmetry line. Optionally, the base 10 is injection molded of a plastic material.

[0037] For further information, see Figure 5-6 The first card pin 11 includes: a first elastic portion 111, a second elastic portion 112, and a connecting portion 113. One end of the first elastic portion 111 is connected to the connecting portion 113, one end of the second elastic portion 112 is connected to the connecting portion 113, and the connecting portion 113 is connected to the base 10. A clamping groove 114 is formed between the first elastic portion 111 and the second elastic portion 112. When the first card pin 11 is connected to the pin of the driving motor 3, the pin of the driving motor 3 is clamped in the clamping groove 114. Optionally, the second card pin 12 has the same structure as the first card pin 11.

[0038] Specifically, the clamping groove 114 includes a guide groove 1141, and the guide groove 1141 is formed between the other end of the first elastic part 111 and the other end of the second elastic part 112, and the groove width of the guide groove 1141 gradually decreases toward the base 10. Optionally, the opposite sides of the first elastic part 111 and the second elastic part 112 are arc-shaped surfaces, so that when the first clamping pin 11 is connected to the pin of the driving motor 3, the pin of the driving motor 3 will first enter the guide groove 1141, and the groove width design of the guide groove 1141 and the arc-shaped surface design on the opposite side can more smoothly guide and clamp the pin of the driving motor 3, so that it can be smoothly clamped into the accommodating groove 1142 closer to the base 10. Optionally, the guide groove 1141 is a V-structure. Optionally, the shortest distance between the first elastic part 111 and the second elastic part 112 is less than the diameter of the positive pin and the negative pin of the driving motor 3. It can be understood that the first elastic portion 111 and the second elastic portion 112 are made of hardware material, but at the same time they also have a certain elasticity, so that when the pin of the drive motor 3 is inserted, the first elastic portion 111 and the second elastic portion 112 will be forced to separate by a certain distance so that the pin of the drive motor 3 can pass through the guide groove 1141 and enter the receiving groove 1142. After the pin of the drive motor 3 passes through the guide groove 1141, the first elastic portion 111 and the second elastic portion 112 will rebound to clamp the pin of the drive motor 3 in the receiving groove 1142.

[0039] Specifically, the snap-in groove 114 also includes a receiving groove 1142 connected to the guide groove 1141. One end of the first elastic portion 111, one end of the second elastic portion 112 and the connecting portion 113 form the receiving groove 1142. The groove width of the receiving groove 1142 first increases and then decreases toward the direction of the base 10. When the pin of the drive motor 3 is guided by the guide groove 1141 to slide into the shortest distance between the first elastic portion 111 and the second elastic portion 112, it will enter the receiving groove 1142.

[0040] Further, in order to prevent the first PCB connector 13, the second PCB connector 14 and the PCB board 2 from being skewed during the connection and assembly process, a PCB support 15 is also provided on the base 10. The PCB support 15 and the first PCB connector 13 and the second PCB connector 14 are distributed in a triangular shape. The triangular distribution design makes the structure of the adapter 1 more stable when it is assembled and connected to the PCB board 2, and it is not easy to be displaced and tilted. Optionally, when the adapter 1 is connected to the drive motor 3, the direction of the adapter 1 to the drive motor 3 is preset as the first direction, and the direction perpendicular to the first direction on the horizontal plane is the second direction, the first PCB connector 13 extends along the second direction on the base 10, the second PCB connector 14 extends along the second direction on the base 10, and the PCB support 15 extends along the first direction on the base 10. Optionally, the PCB support 15 is arranged on the perpendicular bisector of the connection line between the first PCB connector 13 and the second PCB connector 14, and further, the PCB support 15 is located on the side away from the first clamp and the second clamp. It should be explained that, in addition to slots corresponding to the first PCB connector 13 and the second PCB connector 14, the PCB board 2 is also provided with slots corresponding to the PCB support 15. Generally, when assembling the adapter 1 in this embodiment, it is necessary to first insert the first PCB connector 13, the second PCB connector 14 and the PCB support 15 into the corresponding slots of the PCB board 2, and then weld the first PCB connector 13 and the second PCB connector 14 to the PCB board 2.

[0041] Furthermore, in order to make the installation position of the adapter device 1 in this embodiment more accurate during assembly, a positioning column 16 is further provided on the base 10, and a through hole corresponding to the positioning column 16 is further provided on the PCB board 2. Optionally, there are two positioning columns 16, which are respectively provided on one side of the first PCB board 2 connector and one side of the second PCB board 2 connector.

[0042] Furthermore, although the adapter 1 can be relatively fixed with the PCB board 2 in the horizontal direction during the assembly process, relative displacement in the vertical direction may still occur during the actual assembly process, and even the adapter 1 may be installed crookedly. Therefore, in this embodiment, an extended protruding abutment member 17 is further provided on the base 10, and the abutment member 17 is used to abut against the PCB board 2.

[0043] Specifically, there are at least four abutting members 17, and they are distributed in a rectangular shape, and the first PCB connector 13 and the second PCB connector 14 are located within the enclosed range of the abutting members 17. Optionally, the protruding height of the abutting members 17 is lower than the extended height of the first PCB connector 13, the second PCB connector 14, and the PCB support member 15, and the protruding heights of the abutting members 17 are consistent, so that after the first PCB connector 13, the second PCB connector 14, and the PCB support member 15 are inserted into the slots of the PCB board 2, each abutting member 17 abuts against the board surface of the PCB board 2, and then the first PCB connector 13, the second PCB connector 14 and the PCB board 2 are welded, thereby ensuring the stability of the assembly of the adapter 1 and reducing the difficulty of assembly.

[0044] Further, the base 10 includes: a PCB connection portion 101 and a first motor connection portion 102 and a second motor connection portion 103, wherein the first motor connection portion 102 and the second motor connection portion 103 are respectively connected to the same side of the PCB connection portion 101, the first card pin 11 is arranged on the first motor connection portion 102, and the second card pin 12 is arranged on the second motor connection portion 103; the first PCB connection member 13 and the second PCB connection member 14 are both arranged in the PCB connection portion 101. Optionally, the PCB connection portion 101 is rectangular.

[0045] Optionally, the abutment member 17 includes two first abutment structures 171 and two second abutment structures 172, the first abutment structure 171 is an extension protrusion at two top corners of the PCB connection part 101 away from the first motor connection part 102 and the second motor connection part 103, and the first abutment structure 171 is arc-shaped; the second abutment structure 172 is an extension protrusion at two top corners of the PCB connection part 101 close to the first motor connection part 102 and the second motor connection part 103, and the second extension protrusion is L-shaped.

[0046] Compared with the prior art, the adapter device between the PCB board and the motor of the utility model integrates the first card pin, the second card pin connected to the drive motor and the first PCB connector and the second PCB connector connected to the PCB board into a whole through a base, thereby reducing the influence of the first card pin, the second card pin, the first PCB connector and the second PCB connector on the external environment, making the connection between the PCB board and the drive motor more stable.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
