Technical Field

[0001] The present application relates to the technical field of automobile air conditioning, and in particular to an automobile air conditioning damper actuator. Background Art

[0002] With the continuous development of the automobile industry, the performance and reliability of automobile air conditioning systems, as important equipment to improve passenger comfort, have received more and more attention. In automobile air conditioning systems, the damper actuator is a key component that controls the direction and flow of air, which directly affects the cooling and heating effects of the air conditioning system.

[0003] In the prior art, the automotive air-conditioning damper actuator is mainly composed of an actuator upper cover, an actuator lower cover, a motor, a gear set, a circuit board and other parts. However, the motor terminals and the terminals on the circuit board are mostly connected by atomic wire manual soldering. Manual soldering is not only prone to false welding, poor welding or leaking welding, but also inconvenient for staff to repair and replace the motor. Summary of the invention

[0004] In order to improve the stability of the connection between the motor and the circuit board and facilitate the subsequent maintenance and replacement of the motor, the present application provides an automobile air-conditioning damper actuator.

[0005] The present application provides an automotive air conditioning damper actuator that adopts the following technical solution:

[0006] An automobile air conditioner damper actuator comprises an actuator upper cover, a lower cover, a motor and a circuit board. The motor terminal is provided with a pin for connecting to the circuit board. The circuit board is correspondingly provided with a connector. The pin can be plugged into the connector to transmit electrical signals.

[0007] By adopting the above technical solution, when the staff needs to install the motor, first place the motor on the inner wall of the lower cover, and align the pins at the motor terminals with the connectors on the circuit board, then plug the pins at the motor terminals into the connectors on the circuit board, and finally cover the upper cover and connect the upper cover to the lower cover, so that it is convenient for the staff to install the motor; when the motor needs to be repaired or replaced, the staff can open the upper cover and directly move the motor until the pins on the motor are away from the connectors on the circuit board, and the disassembly of the motor can be completed, so that it is convenient to repair or replace the motor. The whole process can reduce the work intensity of the staff, thereby improving work efficiency.

[0008] Preferably, a positioning block is fixedly provided on the motor, and a positioning groove for inserting the positioning block is formed on the inner wall of the lower cover.

[0009] By adopting the above technical solution, the staff can directly insert the positioning block on the motor into the positioning groove. At this time, the pins at the motor terminal are aligned with the connector on the circuit board, which can further reduce the work intensity of the staff.

[0010] Preferably, a push plate is slidably provided on the inner wall of the lower cover at a position away from the circuit board, and the push plate can abut and cooperate with the side of the motor away from the circuit board. An abutment block is fixedly provided on the inner wall of the upper cover, and a side of the abutment block close to the push plate is provided with an inclined surface, and the abutment block can slide and cooperate with the push plate through the inclined surface.

[0011] By adopting the above technical solution, when the staff inserts the positioning block on the motor into the positioning groove, the push plate is always in a position away from the motor. At this time, the upper cover can be directly covered. During this period, the abutment block on the upper cover can push the push plate to move toward the motor through the inclined surface, and then the push plate can push the motor to move toward the direction of the connector on the circuit board. When the upper cover and the lower cover are completely fitted together, the pins at the motor terminal have been plugged into the connector on the circuit board, which can greatly reduce the work intensity of the staff.

[0012] Preferably, a fixing plate 1 is fixedly provided on the inner wall of the lower cover, a return spring is provided between the fixing plate 1 and the push plate, and two ends of the return spring are respectively fixedly provided on the push plate and the fixing plate 1.

[0013] By adopting the above technical solution, when the push plate moves toward the direction close to the circuit board, the return spring is stretched. Later, when the staff needs to repair or replace the motor, the upper cover can be opened. When the abutment block on the upper cover is away from the push plate, the elastic force of the return spring can pull the push plate to the initial position, thereby facilitating the staff to take out the motor and reducing the staff's workload.

[0014] Preferably, a buffer assembly is provided on the inner wall of the lower cover, and the buffer assembly includes buffer plate 1, buffer plate 2, spring 1 and spring 2. The buffer plate 1 and buffer plate 2 can slide on the inner wall of the lower cover, and the buffer plate 1 and buffer plate 2 can respectively abut against the front and rear ends of the motor, and the two ends of the spring 1 are respectively fixedly provided on the push plate and the buffer plate 1; a fixed plate 2 is fixedly provided on the lower cover near the rear end of the motor, and the two ends of the spring 2 are respectively fixedly provided on the buffer plate 2 and the fixed plate 2.

[0015] By adopting the above technical solution, when the actuator is working normally, the motor may move along the axial direction of its rotating shaft. Therefore, the buffer assembly provided can buffer the front and rear ends of the motor, reducing the possibility of damage to the front and rear ends of the motor due to rigid contact with the inner wall of the upper cover and the inner wall of the lower cover; when the staff needs to repair or replace the motor and open the upper cover, the elastic force of the second spring can push the pin at the motor terminal away from the connector on the circuit board through the second buffer plate, thereby making it easier for the staff to remove the motor and reducing the staff's work intensity.

[0016] Preferably, a clamping mechanism is provided on the inner wall of the lower cover at two opposite sides of the motor, and the clamping mechanism comprises a fixing plate three, a clamping plate, a support plate, a limit block, and a spring three; the fixing plate three is fixedly provided on the inner wall of the lower cover, the clamping plate slides on the inner wall of the lower cover, a connecting rod is fixedly provided on the clamping plate, the connecting rod is slidably provided on the fixing plate three, and a baffle is fixedly provided on the other end of the connecting rod;

[0017] One end of the support plate is fixedly arranged on the fixed plate three, the limit block slides on the support plate, and the baffle plate can abut against the side of the limit block away from the fixed plate three. The side of the limit block close to the fixed plate three is provided with an inclined surface, and the limit block can slide and cooperate with the baffle plate through the inclined surface; the clamping mechanism also includes a driving component for driving the limit block to move, and the two ends of the spring three are respectively fixedly arranged on the clamping plate and the fixed plate three, and the clamping mechanism also includes a reset component for resetting the clamping plate; a reset member for resetting the limit block is provided on the support plate.

[0018] By adopting the above technical solution, when the staff places the motor on the lower cover, the clamping plate is always located away from the motor, at which time the spring three is in a compressed state, and the baffle plate abuts against the side of the limit block away from the fixed plate three; subsequently, when the staff puts on the upper cover, the drive assembly can be triggered to drive the limit block to move to a position away from the baffle plate until the limit block moves to a position away from the baffle plate, at which time the spring three can push the clamping plate to abut against the motor; during normal operation of the execution structure, the motor may be offset, so the clamping plates located on both sides of the motor can clamp and fix the motor, reducing the strength of the motor offset, and at the same time, the elastic force of the set spring three can buffer the offset of the motor, reducing the possibility of damage to the motor and the upper cover and the inner wall of the lower cover due to rigid contact; at the same time, when the motor needs to be replaced, the clamping structure can clamp motors of different specifications or sizes, thereby making motor replacement more possible.

[0019] Preferably, the driving assembly includes a support rod, a push rod, a driving rod and a spring four, one end of the support rod is fixedly arranged on the support plate, the push rod is hinged to the support rod, one end of the driving rod is fixedly arranged on the inner wall of the upper cover, the other end of the driving rod can abut against one end of the push rod, the other end of the push rod can abut and cooperate with the limit block, and the two ends of the spring four are respectively fixedly arranged on the push rod and the support plate.

[0020] By adopting the above technical solution, during the process of the upper cover moving closer to the lower cover, the driving rod can push one end of the push rod to cause the push rod to rotate, the spring four is compressed, and the other end of the push rod can push the limit block to move in the direction away from the baffle, thereby reducing the difficulty of the limit block moving; when the upper cover moves in the direction away from the lower cover, the elastic force of the spring four can cause the push rod to rotate to the initial position.

[0021] Preferably, the reset assembly includes a push rod and a push block, one end of the push rod is fixedly arranged on the inner wall of the upper cover, the push block is fixedly arranged on the push rod, and a slope is provided on the side of the push block close to the baffle, and the push block can be slidably matched with the baffle through the slope.

[0022] By adopting the above technical solution, when the upper cover moves away from the lower cover, the upper cover can drive the push rod and the push block to move. The push block can gradually push the baffle to move away from the fixed plate three through the inclined surface. The baffle can drive the clamping plate to gradually move away from the motor through the connecting rod, thereby making it easier for the staff to remove the motor and reducing the work intensity of the staff.

[0023] Preferably, the inner wall of the upper cover and the inner wall of the lower cover are both provided with buffer pads, and the upper and lower sides of the motor can abut against the buffer pads on the upper cover and the lower cover respectively.

[0024] By adopting the above technical solution, the motor inside the actuator may rotate during normal operation, and the provided buffer pad can buffer the motor, reducing the possibility of damage due to rigid contact between the upper and lower sides of the motor and the inner wall of the upper cover and the inner wall of the lower cover.

[0025] Preferably, a guide rod is provided on the inner wall of the lower cover, the guide rod is slidably provided on the fixing plate 1, and one end of the guide rod is fixedly provided on the push plate.

[0028] 1. When the staff needs to install the motor, first place the motor on the inner wall of the lower cover, and align the pins at the motor terminal with the connector on the circuit board, then plug the pins at the motor terminal into the connector on the circuit board, and finally cover the upper cover and connect the upper cover with the lower cover, so that it is convenient for the staff to install the motor; when the motor needs to be repaired or replaced, the staff can open the upper cover and directly move the motor until the pins on the motor are away from the connector on the circuit board, so as to complete the disassembly of the motor, which is convenient for the repair or replacement of the motor. The whole process can reduce the work intensity of the staff, thereby improving work efficiency;

[0029] 2. The staff can directly insert the positioning block on the motor into the positioning slot. At this time, the pins at the motor terminal are aligned with the connector on the circuit board, which can further reduce the staff's work intensity;

The whole process can reduce the work intensity of the staff and thus improve work efficiency.

[0042] like Figure 3 and Figure 4As shown, a positioning block 7 is fixedly provided at the bottom of the motor 3, and a positioning groove 8 for the positioning block 7 to be inserted is opened on the inner wall of the lower cover 2. The positioning groove 8 extends along the axial direction of the rotating shaft of the motor 3, and the width of the positioning groove 8 near the circuit board 4 is greater than the width of the positioning block 7; the staff can directly insert the positioning block 7 on the motor 3 into the positioning groove 8, at this time, the pin 5 at the terminal of the motor 3 is aligned with the connector 6 on the circuit board 4, thereby being able to further reduce the work intensity of the staff.

At this time, the upper cover 1 can be directly covered. During this period, the abutment block 10 on the upper cover 1 can push the push plate 9 to move toward the motor 3 through the inclined surface, and then the push plate 9 can push the motor 3 to move toward the connector 6 on the circuit board 4. When the upper cover 1 and the lower cover 2 are completely fitted together, the pins 5 at the terminal of the motor 3 have been plugged into the connector 6 on the circuit board 4, which can greatly reduce the work intensity of the staff.

[0046] like Figure 3 and Figure 4As shown, when the push plate 9 moves toward the direction close to the circuit board 4, the return spring 12 is stretched. Later, when the staff needs to repair or replace the motor 3, the upper cover 1 can be opened. When the abutment block 10 on the upper cover 1 is away from the push plate 9, the elastic force of the return spring 12 can pull the push plate 9 to the initial position, thereby making it easier for the staff to take out the motor 3 and reducing the staff's work intensity.

[0047] like Figure 3 and Figure 4 As shown, the guide rod 13 can guide the movement of the push plate 9, thereby reducing the possibility of the push plate 9 being offset.

There are multiple springs 18, and they are all arranged in the horizontal direction. The two ends of the spring 2 18 are respectively fixed to the buffer plate 2 16 and the fixed plate 2 19.

[0049] like Figure 3 and Figure 4 As shown, when the actuator is working normally, the motor 3 may move along the axial direction of its rotating shaft, so the buffer assembly 14 provided can buffer the front and rear ends of the motor 3, reducing the possibility of damage to the front and rear ends of the motor 3 due to rigid contact with the inner wall of the upper cover 1 and the inner wall of the lower cover 2; when the staff needs to repair or replace the motor 3 and open the upper cover 1, the elastic force of the spring 2 18 can push the pin 5 at the terminal of the motor 3 away from the connector 6 on the circuit board 4 through the buffer plate 2, thereby making it easier for the staff to remove the motor 3 and reducing the work intensity of the staff.

[0052] like Figure 5 and Figure 6As shown, when the staff puts the motor 3 on the lower cover 2, the clamping plate 202 is always located away from the motor 3. At this time, the spring three 205 is in a compressed state, and the baffle 207 abuts against the side of the limit block 204 away from the fixed plate three 201; subsequently, when the staff puts the upper cover 1 on, the driving assembly 208 can be triggered to drive the limit block 204 to move to a position away from the baffle 207, until the limit block 204 moves to a position away from the baffle 207, at which time the spring three 205 can push the clamping plate 202 to abut against the motor 3; During normal operation of the row structure, the motor 3 may be offset. Therefore, the clamping plates 202 located on both sides of the motor 3 can clamp and fix the motor 3, reducing the strength of the motor 3 being offset. At the same time, the elastic force of the spring three 205 can buffer the offset of the motor 3, reducing the possibility of damage to the motor 3 and the upper cover 1 and the inner wall of the lower cover 2 due to rigid contact. At the same time, when the motor 3 needs to be replaced, the clamping structure can clamp motors 3 of different specifications or sizes, thereby making it more possible to replace the motor 3.

[0055] like Figure 5 and Figure 6As shown, the reset assembly 209 includes a push rod 2091 and a push block 2092. One end of the push rod 2091 is fixedly arranged on the inner wall of the upper cover 1, and the push block 2092 is fixedly arranged on the side of the bottom end of the push rod 2091 close to the baffle 207.
