[0024] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples. Example

[0025] As attached Figure 1 To Attachment Figure 6 As shown:

[0026] The utility model provides a car door handle rotation actuator, comprising: a mounting frame 1; a rectangular notch 1020 structure is opened on one side of the mounting frame 1, and an L-shaped protrusion structure is arranged on the front side of the mounting frame 1; a driving motor 101 is fixedly arranged on the front side of the L-shaped protrusion of the mounting frame 1; and a first worm 102 is arranged at the bottom of the driving motor 101 for transmission connection.

[0027] Among them, a cylindrical transmission rod 103 is rotatably set at the bottom of the front side of the mounting frame 1; a first worm gear 1031 is fixedly set on the outer side of the left end of the transmission rod 103, and the first worm gear 1031 is meshingly connected with the first worm 102; a second worm gear 1032 is fixedly set on the outer side of the right end of the transmission rod 103.

[0028] A first bump 1011 and a second bump 1012 are disposed on the L-shaped protruding structure 1010 , and the first bump 1011 is higher than the second bump 1012 .

[0029] The first protrusion 1011 is arranged horizontally, and the second protrusion 1012 is arranged longitudinally. A transmission bracket 204 is arranged on the first protrusion 1011 for mounting one end of the transmission rod 103 , and a motor bracket 201 is arranged on the end of the second protrusion 1012 for supporting the motor.

[0030] It can be understood that the cavity formed between the first protrusion 1011, the second protrusion 1012 and the motor bracket 201 is used to place the main body of the drive motor 101. The rear end of the drive motor 101 is mounted on the motor bracket 201, and the output end is arranged below the first worm gear 1031. Since the first worm gear 1031 is arranged on the transmission rod 103, and the transmission rod 103 is mounted and fixed on the transmission bracket 204, the output end of the drive motor 101 does not need to be mounted and fixed, and the drive motor is clamped and fixed by the motor bracket 201 and the first worm gear 1031.

[0031] The mounting frame 1 is also provided with an arc-shaped cavity 203, a second bracket 1013 and a third bracket 202. The second bracket 1013 is arranged outside the arc-shaped cavity 203, and the third bracket 202 is arranged outside the rectangular notch 1020. The second bracket 1013 and the third bracket 202 are far away from each other.

[0032] A second worm gear 104 is rotatably disposed on the right front side of the mounting frame 1 , and the second worm gear 104 is meshingly connected with the second worm 1032 .

[0033] The lower end of the arc cavity 203 is sealed, which can prevent impurities from entering the lower part when the second worm gear 104 is working. The rectangular notch opened on the adjacent side of the arc cavity 203 is also provided with symmetrical side recessed parts, which can increase the convenience of loading and unloading.

[0034] Among them, a locking device 105 is rotatably arranged inside the rectangular notch on one side of the mounting frame 1, and the locking device 105 is coaxially arranged on the connecting rod 1040 with the second worm gear 104. The connecting rod 1040 is fixedly connected to the second worm gear 104 and the locking device 105 in sequence, and the interval is adjusted by a nut, so the locking device 105 can be adjusted forward and backward.

[0035] The locking device 105 is provided with a first locking hook 1051 and a second locking hook 1052 , and the first locking hook 1051 and the second locking hook 1052 are oriented in opposite directions, so that when the lock is opened or closed, there will be a limit so as not to rotate too much.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In the utility model, when in use, the mounting bracket 1 is installed on the vehicle. After the vehicle is unlocked, the driving motor 101 is started synchronously to drive the first worm 102 to rotate. The rotation angle of the first worm 102 is 0° to 210°. The first worm 102 drives the transmission rod 103 to rotate by cooperating with the first worm wheel 1031. During the rotation of the transmission rod 103, the second worm 1032 is synchronously driven to rotate. The second worm 1032 drives the second worm wheel 104 to rotate by cooperating with the second worm wheel 104, and synchronously drives the locking device 105 to rotate, thereby completing the unlocking of the vehicle door.
