The driving device 1 according to the embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1 to 25, a driving device 1 according to an embodiment of the present invention includes a driving device 100, a worm 200, a worm wheel 300, a driving rod 400, and a stopper 500.

The worm 200 is in transmission connection with the driving device 100, the worm wheel 300 is in transmission fit with the worm 200, and the driving rod 400 is in threaded fit with the worm wheel 300. The brake 500 is stopped against the turbine 300 for applying a braking force that stops the turbine 300 from rotating. It will be appreciated by those skilled in the art that the brake 500 may be a constant brake that continuously outputs a constant force, or the brake 500 may be switched between different states with the brake 500 outputting different forces in the different states. The driving device 100 may be a motor or other device capable of providing a power source.

For example, the worm 200 and the worm wheel 300 may be engaged with each other, and both the gear of the worm 200 and the gear of the worm wheel 300 may be made of plastic material, so as to reduce the weight of the driving device 1 and reduce the sound pressure level of the driving device 1. When the driving device 100 is a motor, the worm 200 may be mounted to an output shaft of the motor. And, the first brake member 510 is circumferentially fixed with the turbine 300, i.e. the first brake member 510 and the turbine 300 rotate synchronously, for example, the first brake member 510 is provided with a notch 511, the turbine 300 is provided with a snap projection 350, and the snap projection 350 and the notch 511 are matched (as shown in fig. 9).

According to the driving device 1 of the embodiment of the present invention, the worm 200 is in transmission connection with the driving device 100, the worm wheel 300 is in transmission cooperation with the worm 200, the driving rod 400 is in thread fit with the worm wheel 300, the driving device 100 drives the worm 200 to perform rotational motion, the worm 200 drives the worm wheel 300 to perform rotational motion, the worm wheel 300 drives the driving rod 400 to perform linear motion (reciprocating motion), so that an included angle exists between the axial direction of the driving device 100 and the extending direction of the driving rod 400 through the cooperation between the worm 200 and the worm wheel 300, so as to realize the angled transmission of power (for example, vertical transmission, i.e. the included angle between the axial direction of the driving device 100 and the extending direction of the driving rod 400 is 90 °), thereby reducing the number of parts, reducing the assembly difficulty, and realizing that the rotating speed of the driving rod 400 is less than the rotating speed of the driving device 100, and, compared with the related art adopting a straight rod type support rod, the size of the driving device 1 can be reduced, and then the driving device 1 can be suitable for narrow spaces (such as side door metal plates of vehicles), so that the universality of the driving device 1 is improved.

In addition, the brake 500 is abutted against the worm wheel 300 for applying a braking force for stopping the rotation of the worm wheel 300, and due to the cooperation between the worm 200 and the worm wheel 300, the torque of the worm wheel 300 can be increased to reduce the rotating speed of the worm wheel 300, compared with the driving device in the related art that the brake is adopted for braking the worm connected with the motor, the driving device 1 has lower requirements on the brake 500, the cost of the brake 500 can be reduced, and further the cost of the driving device 1 is reduced. And because the area of the axial side of the worm gear 300 is much larger than that of the axial side of the worm 200, the contact area between the brake 500 and the worm gear 300 is larger, thereby increasing the braking effect of the brake 500 on the worm gear 300.

Therefore, according to the utility model discloses drive arrangement 1 has advantages such as with low costs, braking effect is good.

According to some embodiments of the present invention, the brake 500 is located on one axial side of the turbine 300. Since the thickness of the turbine 300 is relatively small, the size of the driving device 1 can be reduced by locating the stopper 500 at one axial side of the turbine 300, which is advantageous for product miniaturization.

According to some embodiments of the present invention, as shown in fig. 2 and 3, the driving device 1 further comprises a housing 600.

The driving device 100, the worm 200, the worm gear 300, the stopper 500, and a part of the driving lever 400 are installed in the housing 600, in other words, the driving device 100, the worm 200, the worm gear 300, and the stopper 500 are installed in the housing 600, and a part of the driving lever 400 is also installed in the housing 600. Wherein the mating positions of the driving rod 400, the worm 200 and the worm wheel 300 are located in the housing 600. By providing the housing 600, it is possible to prevent foreign matters from entering the coupling position between the driving device 100, the worm 200, the worm wheel 300, the driving lever 400, and the stopper 500, and to ensure the stability of the operation of the driving device 1. And the casing 600 can reduce the possibility of damage to the driving device 100, the worm 200, the worm wheel 300, the driving rod 400 and the brake 500, and prolong the service life of the driving device 1. In addition, the housing 600 does not completely cover the driving rod 400, which can save cost and reduce the size of the driving device 1.

According to some embodiments of the present invention, the brake may be switchable between a full braking state, a half braking state and a free state, the full braking force for preventing the rotation of the turbine 300 is applied when the brake 500 is in the full braking state, the half braking force for preventing the rotation of the turbine 300 is applied when the brake 500 is in the half braking state, and the braking force for preventing the rotation of the turbine 300 is cancelled when the brake 500 is in the free state. Thus, by using the brake 500, the locking, free rotation and rotation with certain damping of the driving device 1 can be realized, and when the driving device 1 is applied to a product, the requirement of the product can be met and changed between moving and static.

For example, when the drive device 1 is applied to a door and body connection of a vehicle for realizing automatic opening and closing of the door. When the door is opened, the brake 500 may be switched to a free state where no damping force is applied, thereby reducing the load and sound pressure level of the driving apparatus 100. When the door is opened to a predetermined position halfway, the brake 500 may be switched to a full braking state or a half braking state, at which time a full damping force or a half damping force is applied to stably hover the door at that position.

When the user wants to manually open and close the door, the brake 500 may be switched to a free state where the damping force is not applied, thereby reducing the force required to manually open and close the door.

So, according to the utility model discloses drive arrangement 1 can realize the switching of rotation and locking, has advantages such as the suitability is strong, use comfort is high.

According to some embodiments of the present invention, as shown in fig. 8, the brake 500 includes a first brake component 510 and a second brake component 520. A first brake member 510 is mounted to the transmission assembly and a second brake member 520 is mounted to the housing 600.

For example, the first brake component 510 may be circumferentially fixed with the transmission assembly, i.e., the first brake component 510 may rotate synchronously with the transmission assembly. The second brake member 520 may be circumferentially fixed to the housing 600, i.e., the second brake member 520 may rotate synchronously with the housing 600. And, at least one of the first and second brake members 510 and 520 is movable in the axial direction of the driving rod 400, wherein the first brake member 510 is engageable with the driving assembly, and the second brake member 520 is engageable with the housing 600.

Wherein the first brake member 510 is fully engaged with the second brake member 520 when the brake 500 is in the full braking state, the first brake member 510 is half engaged with the second brake member 520 when the brake 500 is in the half braking state, and the first brake member 510 is disengaged from the second brake member 520 when the brake 500 is in the free state. The brake 500 is provided in a separate structure, which facilitates disassembly and assembly, facilitates maintenance, and enables braking of the driving device 1 in various states.

Further, the first brake component 510 is a first permanent magnet, the second brake component 520 includes a brake shell 521, a second permanent magnet 522 and an electromagnetic piece 523, and is mounted on the outer shell 600, and the second permanent magnet 522 and the electromagnetic piece 523 are disposed in the brake shell 521. The brake shell 521 and the outer shell 600 may be circumferentially fixed, that is, the brake shell 521 and the outer shell 600 may rotate synchronously. Also, the electromagnet 523 may be an electromagnet, which may be provided with a wire harness.

The working principle and the construction of the brake 500 can have the following working modes:

in the first mode, the polarities of the first permanent magnet and the second permanent magnet 522 are opposite, when the brake 500 is in a half-braking state, the electromagnetic piece 523 is not electrified, and the first permanent magnet is half-combined with the brake shell 521 under the suction force of the second permanent magnet 522, so that a damping torque is generated on the turbine 300, and the integral internal resistance of the driving device 1 is increased; when the brake 500 is in a full braking state, the electromagnetic member 523 is electrified reversely to generate a magnetic force with a polarity opposite to that of the first permanent magnet, the first permanent magnet is fully combined with the brake shell 521 under the attraction force of the electromagnetic member 523 and the second permanent magnet 522, so that the damping torque to the turbine 300 is increased, wherein when the damping force is greater than the rotating force of the turbine 300, the driving device 1 is in a locking state; when the brake 500 is in a free state, the electromagnetic member 523 is energized in a positive direction to generate a magnetic force having the same polarity as that of the first permanent magnet, and the first permanent magnet is separated from the brake case 521 under the repulsive force of the electromagnetic member 523 and the attractive force of the second permanent magnet 522, so that the damping torque to the turbine 300 is reduced to disappear, and the internal resistance of the entire driving device 1 is reduced.

In the second mode, the polarities of the first permanent magnet and the second permanent magnet 522 are the same, when the brake 500 is in a free state, the electromagnetic piece 523 is not electrified, and the first permanent magnet is separated from the brake shell 521 under the repulsive force of the second permanent magnet 522, so that no damping torque is generated on the turbine 300, and the integral internal resistance of the driving device 1 is reduced; when the brake 500 is in a full braking state, the electromagnetic piece 523 is electrified reversely to generate a magnetic force with a polarity opposite to that of the first permanent magnet, and the first permanent magnet is fully combined with the brake shell 521 under the attraction force of the electromagnetic piece 523 and the second permanent magnet 522, so that a damping torque is generated on the turbine 300, the internal resistance of the whole driving device 1 is increased, wherein when the damping force is greater than the rotating force of the turbine 300, the driving device 1 is in a locking state; when the brake 500 is in a half-braking state, the electromagnetic member 523 is energized in a reverse direction to generate a magnetic force with a polarity opposite to that of the first permanent magnet, and the first permanent magnet is half-combined with the brake shell 521 under the attraction force of the electromagnetic member 523 and the second permanent magnet 522, so that a damping torque is generated on the turbine 300, and the internal resistance of the whole driving device 1 is increased.

The energizing voltage of the electromagnetic member 523 when the brake 500 is in the full braking state is greater than the energizing voltage of the electromagnetic member 523 when the brake 500 is in the half braking state. In addition, the electromagnetic member 523 generates a magnetic force having the same polarity as that of the first permanent magnet by applying a positive current, and the first permanent magnet is separated from the brake case 521 by a repulsive force between the electromagnetic member 523 and the second permanent magnet 522, so that there is no damping torque to the turbine 300, and the internal resistance of the entire driving apparatus 1 is reduced.

The following is an example of a case applied to a vehicle in a second manner:

when the vehicle is an electric door, the electromagnetic piece 523 is not electrified, and the internal resistance of the driving device 1 is minimum, so that the load of the driving device 100 can be reduced, and the sound pressure level of the driving device 100 is further reduced; when the vehicle door is opened to a preset position or stops halfway, the electromagnetic piece 523 is electrified and reversely electrified, the first permanent magnet is fully combined with the brake shell 521 under the suction force of the electromagnetic piece 523 and the second permanent magnet 522, damping torque is generated on the turbine 300, the internal resistance of the driving device 1 is increased, and the vehicle door can stably hover at the position at the moment; when a user wants to manually open and close the vehicle door, the electromagnetic piece 523 can be powered off, the first permanent magnet is separated from the brake shell 521 under the repulsive force of the second permanent magnet 522, the internal resistance of the driving device 1 is minimum, the resistance of manually opening and closing the vehicle door is reduced, the vehicle performance is optimized, and the use comfort of the user is improved.

According to some embodiments of the present invention, as shown in fig. 8, the second brake component 520 further includes a friction plate 524, and the friction plate 524 is disposed between the brake housing 521 and the first permanent magnet. The friction plate 524 may be made of a wear-resistant material, and the friction plate 524 may be circumferentially fixed to the brake case 521, that is, the friction plate 524 may rotate synchronously with the brake case 521. By providing friction plates 524, the service life of brake 500 is increased.

According to some embodiments of the present invention, as shown in fig. 18-20, the first brake component 510 is a brake pad, the second brake component 520 includes a brake shell 521, an electromagnetic piece 523 and a wave spring 525, the brake shell 521 is mounted on the housing 600, the electromagnetic piece 523 is disposed in the brake shell 521, and the wave spring 252 is disposed between the electromagnetic piece 523 and the brake pad.

For example, the brake shell 521 may be circumferentially fixed with the housing 600, i.e., the brake shell 521 may rotate synchronously with the housing 600. The brake pad may be a metallic piece. Both axial side surfaces of the wave spring 252 extend in a wave shape in the circumferential direction thereof.

When the brake 500 is in the free state, the electromagnetic piece 523 is not electrified, and the brake piece 521 is separated from the brake shell 521 under the elastic force of the wave spring 525;

when the brake 500 is in the full braking state, the electromagnetic piece 523 is electrified to generate magnetic force, and the brake pad is fully combined with the brake shell 521 under the attraction force of the electromagnetic piece 523 against the elastic force of the wave spring 525;

when the brake 500 is in the half braking state, the electromagnetic piece 523 is electrified to generate magnetic force, and the brake piece is half combined with the brake shell 521 under the attraction force of the electromagnetic piece and overcomes the elastic force of the wave spring 525.

When the brake 500 is in the full braking state, the energization voltage of the electromagnetic member 523 is greater than the energization voltage of the electromagnetic member 523 when the brake 500 is in the half braking state.

The following exemplifies a case where the drive apparatus 1 is applied to a vehicle:

when the vehicle is an electric door, the electromagnetic piece 523 is not electrified, and the internal resistance of the driving device 1 is minimum, so that the load of the driving device 100 can be reduced, and the sound pressure level of the driving device 100 is further reduced; when the vehicle door is opened to a preset position or stopped halfway, the electromagnetic piece 523 is electrified, the brake piece 523 overcomes the elastic force of the wave spring 525 to be fully combined or half combined with the brake shell 521, so as to generate damping torque on the turbine 300, increase the internal resistance of the driving device 1 and enable the vehicle door to stably hover at the position at the moment; when a user wants to manually open and close the vehicle door, the electromagnetic piece 523 can be powered off, the brake piece 521 is separated from the brake shell 521 under the elastic force of the wave spring 525, the internal resistance of the driving device 1 is minimum, the resistance of manually opening and closing the vehicle door is reduced, the vehicle performance is optimized, and the use comfort of the user is improved.
