[0045] like Figures 1 to 6 As shown, the utility model provides a controller, including a housing 10, a connector 20, a drive board 30 and a control board 40. The connector 20 is mounted on the bottom wall 11 of the housing 10 and is located on one side of the housing 10 in the first direction X. The other side of the bottom wall 11 of the housing 10 is used to mount the motor. The drive board 30 and the control board 40 are both mounted in the housing 10. The drive board 30 and the control board 40 are spaced apart in the second direction Y. The drive board 30 is mounted with a quick-connect connector 31. The quick-connect connector 31 includes two clips. The motor is protruded with a plug-in male connector. The plug-in male connector can pass through the bottom wall 11 of the housing 10 and the control board 40 and then float and connect with the quick-connect connector 31 and be electrically connected. The two clips can clamp the plug-in male connector and the clamping direction is perpendicular to the plug-in direction of the plug-in male connector; the plug-in direction is parallel to the second direction Y, and the clamping direction is in the same plane as the first direction X, and the plane is perpendicular to the second direction Y.

[0046] The motor and the connector 20 are located on the same side of the housing 10 in the second direction Y, that is, the motor and the connector 20 are both connected to the bottom wall 11 of the housing 10, so that after the controller and the motor are assembled, the assembly structure is compact and occupies little space. The motor can be electrically connected to the drive plate 30, and the drive plate 30 controls the opening and closing and other states of the motor. In this embodiment, the motor is provided with a plug-in male connector, and the drive plate 30 is installed with a quick connector 31. The plug-in male connector and the quick connector 31 are floatingly plugged in, that is, the plug-in male connector can move relative to the quick connector 31 or has a tendency to move relative to the quick connector 31, and the moving direction intersects with the clamping direction of the two clips. In this way, it can compensate to a certain extent for the problem of misalignment of the connection position between the motor and the housing 10 and the connection position between the motor and the drive plate 30 due to processing errors, facilitate installation, and have stronger compatibility. Moreover, when the motor starts, the motor itself always vibrates. The floating connection can provide a certain degree of freedom for the vibration, avoiding the vibration from being transmitted to the drive plate 30, causing the vibration plate to vibrate relative to the housing 10.

[0047] It should be noted that the motor and the bottom wall 11 of the housing 10 need to be connected and fixed by threaded fasteners.

[0048] Furthermore, the contact surface between the clip and the male connector is wavy, which makes it easier to insert the male connector.

[0049] Furthermore, the male connector is a sheet-like structure.

[0050] Furthermore, the drive plate 30 , the control plate 40 and the housing 10 are all fixed by threaded fasteners.

[0051] Optionally, multiple quick connectors 31 are provided, and the clamping directions of the multiple quick connectors 31 are arranged at an angle. In this way, by providing multiple quick connectors 31, the stability of the mechanical connection between the motor and the connector and the stability of the electrical connection can be ensured.

[0052] Optionally, the bottom wall 11 of the housing 10 is provided with a limiting opening 111, and the peripheral contour of the limiting opening 111 is a non-circular structure when projected in the second direction Y. The motor housing is provided with a plug-in portion, which is inserted into the limiting opening 111, and the outer contour of the plug-in portion does not satisfy the inscribed circle of the limiting opening 111 or is a circular structure with a diameter smaller than the inscribed circle when projected in the second direction Y. With this arrangement, the plug-in portion of the motor is plugged into the limiting opening 111 of the housing 10 along the second direction Y. Since the outer contour of the plug-in portion does not satisfy the inscribed circle of the limiting opening 111 or is a circular structure with a diameter smaller than the inscribed circle, the motor housing and the housing 10 cannot rotate relative to each other when the plug-in portion and the limiting opening 111 are plugged in and limited, and thus remain relatively stable.

[0053] Optionally, the bottom wall 11 of the housing 10 is provided with a protruding stopper 112, and the motor is provided with a corresponding connecting ear. The protruding stopper 112 can be inserted into the connecting ear along the second direction Y. By inserting and limiting the position of the protruding stopper 112 and the connecting ear, the stability between the motor and the housing 10 can be further ensured, and the concentrated force on the plug-in portion of the motor can be reduced.

[0054] Optionally, the controller further includes a floating connector 50 , which is sandwiched between the driver board 30 and the control board 40 in the second direction Y. The floating connector 50 can eliminate misalignment between the control board 40 and the driver board 30 during installation, thereby providing relatively high reliability and wiring freedom.

[0055] It should be noted that the floating connector 50 is a prior art, and its specific structure, working principle and connection method with the driving board 30 or the control board 40 are not described in detail.

[0056] Optionally, the inner circumferential wall 12 of the housing 10 is provided with a protruding support platform 121, and the control board 40 is provided with a corresponding groove, and the support platform 121 can be inserted into the groove. In this way, through the insertion and cooperation between the support platform 121 and the groove, the position of the control board 40 relative to the housing 10 can be controlled, and the stability of the drive board 30 and the housing 10 can be maintained.

[0057] Optionally, the floating connector 50 is located in the middle of the driving plate 30, and the peripheral side of the driving plate 30 is overlapped on the support platform 121. In this way, the driving plate 30 can be supported by the floating connector 50 and the support platform 121, expanding the support area and avoiding local stress.

[0058] Optionally, the driver board 30 is provided with a first plugging hole, and the axial profile of the first plugging hole is a shuttle shape when projected in the second direction Y. The signal identification end of the connector 20 is provided with a first fisheye terminal 21, and the first fisheye terminal 21 is plugged into the first plugging hole in a one-to-one correspondence along the second direction Y. Specifically, the plugging process of the first fisheye terminal 21 and the first plugging hole is as follows:

[0059] S1. The first fisheye terminal 21 is pre-placed into the first plug-in hole. Only the tip of the first fisheye terminal 21 is inserted into the first plug-in hole, and the first fisheye terminal 21 has not yet been deformed.

[0060] S2. The first fisheye terminal 21 begins to be pressed into the first plug hole, and the fisheye portion of the first fisheye terminal 21 is squeezed and deformed.

[0061] S3. The first fisheye terminal 21 continues to be pressed into the first plug hole, and the fisheye portion of the first fisheye terminal 21 is deformed and pressed, and the deformation amount is reduced.

[0062] It should be noted that the fisheye terminal is an existing structure and will not be described in detail here.

[0063] Optionally, the control board 40 is provided with a second plug-in hole, and the axial profile of the second plug-in hole in the projection in the second direction Y is shuttle-shaped. The signal identification end of the connector 20 is protruding with a second fisheye terminal 22, and the second fisheye terminal 22 is plugged into the second plug-in hole one-to-one along the second direction Y.

[0064] In this way, the driving board 30 and the connecting piece 20 as well as the control board 40 and the connecting piece 20 are connected by fisheye crimping, which replaces the method of fixing the driving board 30, the connecting board and the connecting piece 20 according to the welding process, and has the benefit of a simple assembly process.

[0065] Optionally, an end cap 60 is further included. The end cap 60 is engaged with the housing 10 to form a closed inner cavity. The control board 40 and the driver board 30 are both installed in the inner cavity. The driver board 30 is adjacent to the end cap 60. The end cap 60 is provided with heat dissipation ribs 61 on the side facing away from the driver board 30. In this way, the driver board 30 can dissipate heat through the end cap 60. The provision of heat dissipation ribs 61 on the end cap 60 can increase its contact area with the air and improve heat dissipation efficiency.

[0066] Furthermore, the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention.
