Description

Technical Field

[0001] The utility model relates to a novel actuator motor fixing structure. Background Art

[0002] Most car headlights are equipped with a dimming actuator to adjust the headlight's illumination direction from a deviated direction to a standard direction and improve the headlight lighting effect. The dimming actuator pulls or pushes the reflector in the headlight, causing the reflector to rotate up and down around the horizontal axis to adjust the headlight's illumination angle, thereby achieving an up and down pitch illumination effect of the headlight light.

[0003] In the dimming actuator, the motor is connected to the ball head rod through a transmission mechanism. The positioning clamp on the ball head rod is engaged with the sliding rod of the potential switch. The rotational motion of the motor is converted into linear motion of the ball head rod through gear transmission and thread transmission. At the same time, the ball head rod drives the sliding rod to slide, so as to improve the dimming accuracy of the dimming actuator.

[0004] The motor in the current actuator has no mechanism to limit and fix it, which causes the motor to vibrate during operation, affecting the transmission efficiency, poor stability, and shortening the service life of the actuator. Utility Model Content

[0005] The utility model provides a novel actuator motor fixing structure.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A new actuator motor fixing structure includes a top cover and a base that cooperate with each other, a motor is arranged on the inside of the base and the top cover, the motor includes a tail and a drive shaft, a vertically extending limit arm is arranged on the inside of the top cover, and a rib and a limit part are arranged on the inside of the base. The limit part is located at the rear of the motor, and the limit part includes two relatively arranged protrusions, the two protrusions are located on both sides of the tail and abut the tail, and the limit arm abuts the top of the motor.

[0008] Preferably, the ends of the first limiting arm and the second limiting arm are both arc-shaped.

[0009] Preferably, there are two ribs and they are spaced apart along the axial direction of the motor.

[0010] Preferably, a support plate is provided in the middle of the base, and a recess is provided on the support plate to cooperate with the driving shaft of the motor.

[0011] Preferably, the limiting arm includes a first limiting arm and a second limiting arm, and the first limiting arm and the second limiting arm are distributed along the axial direction of the motor.

[0012] Compared with the existing technology, the utility model adopts a new actuator motor fixing structure to accommodate the motor through a shell formed by the top cover and the base. The ribs on the base support the bottom of the motor, the limiting part limits and fixes the tail of the motor, and the first limiting arm and the second limiting arm on the inside of the top cover limit and fix the top of the motor, which can effectively prevent the motor from shaking during operation, extend the service life of the actuator, and improve the stability of the actuator.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 3 As shown, a novel actuator motor fixing structure includes a top cover 1 and a base 2 that cooperate with each other. A motor 3 is disposed inside the base 2 and top cover 1. The motor 3 includes a tail portion 31 and a drive shaft 32. A first limiting arm 11 and a second limiting arm 12 are disposed vertically inside the top cover 1. The ends of the first limiting arm 11 and the second limiting arm 12 are both arc-shaped and arranged along the axial direction of the motor 3. A rib 21 and a limiting portion 22 are disposed inside the base 2. There are two ribs 21 and they are spaced apart along the axial direction of the motor 3. The limiting portion 22 is located at the rear of the motor 3 and includes two opposing protrusions 221. The two protrusions 221 are located on either side of the tail portion 31 and abut against the tail portion 31 to limit and fix the motor 3.

[0018] A support plate 23 is provided in the middle of the base 2 , and a recess 231 is provided on the support plate 23 to cooperate with the driving shaft 32 of the motor 3 .

[0019] The bottom support of the motor 3 is set on the rib 21 of the base 2, and the driving shaft 32 of the motor 3 cooperates with the recess 231 of the support plate 23. The tail 31 of the motor 3 is limited and fixed by the two protrusions 221 of the limiting part 22. After the top cover 1 is matched with the base 2, the first limiting arm 11 and the second limiting arm 12 on the inner side of the top cover 1 abut against the top of the motor 3, thereby realizing the limiting fixation of the motor 3.

[0020] The utility model provides a novel actuator motor fixing structure. The housing is formed by the top cover 1 and the base 2 to accommodate the motor 3. The ribs 21 on the base 2 support the bottom of the motor 3. The limiting portion 22 limits and fixes the tail 31 of the motor 3. The first limiting arm 11 and the second limiting arm 12 on the inner side of the top cover 1 limit and fix the top of the motor 3, which can effectively prevent the motor 3 from shaking during operation, extend the service life of the actuator, and improve the stability of the actuator.
