[0002] In the electronic and electrical architecture of vehicles, as the hardware basis for realizing various electronic functions, the performance and reliability of actuators are directly related to the performance and safety of vehicles. With the continuous development of automotive technology, the types and functions of actuators are also constantly increasing. They play an increasingly important role in realizing higher-level autonomous driving and intelligent vehicle functions. The actuators currently introduced on the market have a relatively small output force during operation. When applied to occasions that require a large output force, such as electric suction doors and electric hoods, during the operation of the actuator, the controllable methods are also relatively single, and there are relatively few choices for customers, which brings certain limitations to the application of the actuator;

[0003] Therefore, the utility model provides an actuator integrating electric and manual unlocking, which can achieve large output force, low noise, flexible arrangement position, and manual and electric unlocking. Content of the Utility Model

[0004] The purpose of the utility model is to provide an actuator integrating electric and manual unlocking to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An actuator integrating electric and manual unlocking includes an actuator bottom shell, a motor arranged in the actuator bottom shell, a driving gear and an actuating gear which are cooperatively linked with the output end of the motor. A worm is connected to the output shaft of the motor, and the thread on the outer wall of the worm meshes with the tooth groove on the outside of the driving gear. The axis of the driving gear is rotationally limited in the actuator bottom shell through a limiting shaft;

[0007] A small gear synchronously rotating with the driving gear is connected to the limiting shaft, and the outer wall of the small gear meshes with the teeth on the outer wall of the actuating gear.

The upper cover of the actuator is used to cover and protect the driving gear and the actuating gear in the bottom case of the actuator.

[0010] Further, a touch switch is arranged below the actuating gear, and an output end of the touch switch is connected to a micro switch outside the bottom case of the actuator. The touch switch is used to sense the rotation state of the actuating gear, output information to the micro switch, and compress or release the micro switch according to the set value, so as to judge the position of the locking device cooperated with the actuating gear through the control mechanism.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-3 , the present invention provides a technical solution:

[0022] An actuator integrating electric and manual unlocking, comprising an actuator bottom case 1, a motor 2 arranged in the actuator bottom case 1, a driving gear 3 and an execution gear 4 which are cooperatively linked with the output end of the motor 2. A worm 5 is connected to the output shaft of the motor 2. The thread on the outer wall of the worm 5 meshes with the tooth groove 6 on the outer side of the driving gear 3. The axis of the driving gear 3 is rotationally limited in the actuator bottom case 1 through a first limit shaft 7;

[0023] A pinion 8 which rotates synchronously with the driving gear 3 is connected to the limit shaft, and the outer wall of the pinion 8 meshes with the teeth 9 on the outer wall of the execution gear 4. The axis of the execution gear 4 is rotationally limited in the actuator bottom case 1 through a second limit shaft 10;

[0024] A cam at the top of the second limit shaft 10 of the axis of the execution gear 4 is connected to a fixed rocker arm 11 fixed to the execution gear 4. A buckle 17 on the outer side of the bottom end of the fixed rocker arm 11 is clamped with a movable rocker arm 12 located below the fixed rocker arm 11. A pull wire 13 is connected to the end of the movable rocker arm 12.

[0025] An actuator upper cover 14 covers the actuator bottom case 1. The first limit shaft 7 and the second limit shaft 10 respectively penetrate through the actuator upper cover 14. The fixed rocker arm 11 is arranged above the actuator upper cover 14 and connected to the second limit shaft 10. The actuator upper cover 14 is used to cover and protect the driving gear 3 and the execution gear 4 in the actuator bottom case 1. The fixed rocker arm 11 is located on the actuator upper cover 14 and connected to the pull wire 13, and cooperates with the pull wire 13 to be connected to a device that requires pulling force.

[0026] A touch switch 15 is provided below the actuating gear 4, and the output end of the touch switch 15 is connected to a micro switch outside the bottom case 1 of the actuator. The touch switch 15 is used to sense the rotation state of the actuating gear 4, output the information to the micro switch, and compress or release the micro switch according to the set value, so as to judge the position of the locking device engaged with the actuating gear 4 through the control mechanism.

[0027] A number of buckles 17 are provided on the outside of the bottom case 1 of the actuator. A number of bayonets 18 on the outside of the upper cover 14 of the actuator correspond to and are snap-connected to the buckles 17. After the upper cover 14 of the actuator covers the bottom case 1 of the actuator, the bayonets 18 are docked with the buckles 17. The docking of the bayonets 18 and the buckles 17 realizes the rapid assembly of the upper cover 14 and the bottom case 1 of the actuator.

[0028] The end of the wire rope 13 is connected to the device that requires pulling force. The wire rope 13 is driven as the actuating gear 4 rotates, and outputs force and stroke to the device that requires pulling force, improving the output force and stroke range of the device that requires pulling force.

[0029] The end of the worm 5 is connected to the rotating shaft seat inside the bottom case 1 of the actuator. The rotating shaft seat cooperates with the worm 5 to rotate as the output shaft of the motor 2 rotates, keeping the worm 5 rotating stably.

[0030] For this actuator that combines electric and manual unlocking, when used in cooperation with a device that requires pulling force: the motor 2 operates to generate a driving force for the worm 5 to rotate. Since the thread on the outer wall of the worm 5 meshes with the tooth groove 6 on the outer wall of the push gear 3 when the worm 5 rotates, a rotational acting force is generated on the push gear 3 through the thread. The first limiting shaft 7 limits the push gear 3 in the bottom case 1 of the actuator and cooperates with the push gear 3 to rotate;

[0031] When the push gear 3 rotates, the small gear 8 coaxial with the push gear 3 rotates accordingly, and a driving acting force for pushing the actuating gear 4 to rotate is generated on the actuating gear 4 through the teeth on the outer wall of the small gear 8, so that the actuating gear 4 and the push gear 3 rotate synchronously. The rotation of the actuating gear 4 rotates the fixed rocker arm 11. The fixed rocker arm 11 is connected to the movable rocker arm 12, so as to achieve the purpose of driving the movable rocker arm 12 to rotate by the fixed rocker arm 11. The wire rope 13 at the end of the movable rocker arm 12 generates an output force and a pulling stroke on the device that requires pulling force, increasing the output force of the pulling force on the device and the stroke generated by the pulling force;

[0032] The actuator integrated with electric and manual unlocking is provided with a driving gear 3 and an actuating gear 4 which are braked in cooperation with a motor 2 in the bottom case 1 of the actuator. The actuating gear 4 and the driving gear 3 are synchronously rotated by a pinion 8, so as to realize the effect of the three-stage rotating wheels cooperating with the fixed rocker arm 11, the movable rocker arm 12 and the wire 13 to control the device requiring tension. The actuator has a clutch feature. The actuator integrated with electric and manual unlocking can be applied to the tension device requiring integrated manual and electric opening, thereby improving the application range of the actuator.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
