Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and specifically relates to an electronic actuator for automotive parts. Background Art

[0002] An electronic actuator is a device that can convert an electrical signal into mechanical motion or other physical quantities, thereby realizing the automatic unlocking and resetting of a locking mechanism. In an automobile, it is mainly used to precisely control the actions and states of various components to realize various functions of the vehicle, such as power transmission, chassis control, body system adjustment, etc.

[0003] In a traditional actuator, the user needs to manually press or turn it to complete the unlocking operation. This process greatly increases the complexity during use and reduces the convenience during use. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a new solution for an electronic actuator for automotive parts, which solves problems such as the single way of fixing the motor in the existing device and the vibration force generated during the output of the motor being transmitted back to itself, thereby affecting its own service life.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: An electronic actuator for automotive parts includes a lower housing, a motor, a worm, a torsion spring, a worm gear, an upper housing, a rotating disk and a screw. The actuator can be mainly divided into three modules: a power module, a transmission module and an operation module;

[0006] The power module and the transmission module are arranged between the upper housing and the lower housing, and the z-direction clearance between the operation module and the lower housing is limited by the screw.

[0007] The power module includes a motor. The motor is arranged between the lower housing and the upper housing. A limiting surface is connected to the output end of the motor. One end of the worm is fixedly connected with a limiting rib, and the limiting rib is connected to the limiting surface;

[0008] The transmission module includes a torsion spring, a worm gear and a worm. A second installation groove is formed on the surface of the lower housing. A seventh installation hole is formed on the surface of the worm gear. Both ends of the torsion spring are respectively fixedly connected to the inside of the second installation groove and the seventh installation hole. The worm gear is meshed with the worm;

[0009] The operation module includes a rotating disk. A second claw is fixedly connected to the bottom surface of the rotating disk. A ninth installation hole is formed on the top surface of the worm gear, and the second claw is clamped in the ninth installation hole. The other end of the torsion spring is connected to the rotating disk to transmit power to the rotating disk. Two clamping feet are arranged at the end of the rotating disk to connect to an external product;

[0010] The lower housing is also provided with a second mounting groove, the purpose of which is to prevent the torsion spring from rotating with the actuator when the actuator is working, thereby fixing the actuator and effectively providing a restoring force.

[0011] The worm wheel is provided with a seventh mounting hole, which is used to fix the other end of the torsion spring so that it can bear the force better;

[0012] The worm wheel is provided with a ninth mounting hole, and its function is to cooperate with the claw provided on the rotating disk to prevent the rotating disk from falling out.

[0013] Through the above technical solution: with the cooperation of the worm gear, the "original force" finally acts on the rotating disk, and the rotating disk rotates under the action of the transmission module, so that the product connected to the end of the rotating disk completes the operation, thereby realizing the unlocking function. Finally, after the operation is completed, the rotating disk returns to the initial position driven by the restoring force of the spring, realizing the automatic reset function.

[0014] Preferably, a first mounting groove is opened on the surface of the lower shell, and the worm is arranged inside the first mounting groove, a third mounting hole is opened on the surface of the lower shell, and the worm wheel is arranged inside the third mounting hole, a fourth mounting hole is opened on the surface of the lower shell, and the screw extends into the fourth mounting hole, and a first limit point is fixedly connected to one side of the motor.

[0015] Preferably, a first mounting hole is provided on the motor, a conductive sheet is provided on the surface of the lower housing, and the first mounting hole is connected to the conductive sheet.

[0016] Preferably, a second mounting hole is provided on the outer surface of the lower housing, and the second mounting hole is communicated with the conductive sheet, so that the power supply is connected to the internal conductive sheet.

[0017] Preferably, a first claw is provided on the surface of the lower shell, and the first claw is engaged with the worm gear to prevent the worm gear from falling out after installation.

[0018] Preferably, a fifth mounting hole is provided on the surface of the lower shell, a sixth mounting hole is also provided on the surface of the lower shell, a third claw is provided on the surface of the upper shell, and the third claw is clamped in the inside of the sixth mounting hole and cooperates with the lower shell to fix the internal transmission module.

[0019] Preferably, an eighth mounting hole is opened at the center of the surface of the worm wheel, and the worm wheel is sleeved on the lower shell through the eighth mounting hole.

[0020] Preferably, a second limiting point is provided at one end of the worm, a mounting opening is provided on the surface of the lower shell, and the second limiting point extends into the interior of the mounting opening.

[0021] Preferably, a tenth mounting hole is provided at the center of the top surface of the rotating disk. A boss is connected to the top surface of the rotating disk. The function of the boss is to connect the customer's environmental component, enabling it to rotate together when the actuator rotates, thereby achieving the purpose of unlocking. The upper housing is provided with an eleventh mounting hole, and the two sides of the upper housing are provided with twelfth mounting holes.

[0022] Preferably, for the working process of an electronic actuator for automotive parts, the process includes the following steps:

[0023] S1. The power supply is connected through the second mounting hole of the lower housing and supplies power to the motor through the conducting piece.

[0024] S2. The motor drives the worm to rotate, and drives the worm wheel to rotate through meshing transmission.

[0025] S3. Under the cooperation of the worm wheel and the worm, the original force finally acts on the rotating disk. The rotating disk will rotate together with the transmission module, and then the products connected to the end of the rotating disk will work together, thereby achieving the purpose of unlocking. When unlocking, the worm wheel rotates directly to drive the rotating disk to rotate. At the same time, the compression torsion spring stores energy.

[0026] S4. The boss of the rotating disk drives the external environmental component to complete the unlocking action.

[0027] S5. After power-off, the torsion spring releases energy, which is converted into a restoring force, driving the rotating disk and the power module to rotate in the reverse direction and return to the initial state, and the actuator realizes automatic reset.

[0028] Working principle: Connect the power supply through the second mounting hole of the lower housing. The current is transmitted to the motor through the conducting piece, providing electrical energy for the motor and enabling the motor to have the power basis for working.

[0029] After the motor is powered on and starts working, the limiting surface connected to the output end of the motor drives the limiting rib at one end of the worm connected to it, causing the worm to rotate. The worm meshes with the worm wheel, and the rotational movement of the worm is converted into the rotation of the worm wheel through meshing transmission.

[0030] When the worm wheel rotates, one end of the torsion spring connected in the seventh mounting hole on its surface rotates with the worm wheel. The other end of the torsion spring is fixed in the second mounting groove of the lower housing, so that the torsion spring is compressed and stores elastic potential energy. At the same time, the ninth mounting hole on the top surface of the worm wheel is clamped with the second claw on the bottom surface of the rotating disk, driving the rotating disk to rotate. The boss on the top surface of the rotating disk contacts the external environmental component and drives the external environmental component to complete the unlocking action.

[0031] When the power supply is cut off, the motor stops working. At this time, the elastic potential energy stored in the torsion spring is released, driving the worm wheel to rotate in the reverse direction. The worm wheel drives the rotating disk to rotate in the reverse direction, making the electronic actuator return to the initial state and completing a working cycle.

[0032] The present invention provides an electronic actuator for automotive parts, with the following beneficial effects:

[0033] 1. The present invention eliminates the pressing or rotary unlocking method in the transmission, and at the same time adds the cooperation of worm and worm gear, which not only makes the structure of the actuator simpler, but also saves most of the space, and the structure is simpler.

[0034] 2. Through the combined design of the motor, the limiting surface, the first limiting point and the lower housing, and the electrical connection structure of the first mounting hole and the conduction piece, the precise positioning and reliable power supply of the motor are realized. Through the dual limiting mechanism (mechanical limiting + electrical positioning), it is ensured that the motor maintains stable output in a vibrating environment, solving the problem of the reduction of transmission efficiency caused by the displacement of the motor in the traditional actuator, and is applicable to the working conditions of high-frequency vibration in vehicles.

[0035] 3. The present invention forms a dual connection system through the rotary disk boss and the eleventh mounting hole of the upper housing. The boss provides an active drive interface for the environmental parts, and the tenth mounting hole realizes the mounting positioning. Combined with the claw connection structure of the upper housing, a three-dimensional fixed network is formed, enhancing the overall stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
