Detailed Description

In order to make the technical means, the creation features, the achievement objects and the effects of the invention easy to understand, the following embodiments are specifically described with reference to the accompanying drawings.

< example one >

The automotive glove box door/cover actuator 100 is used to open and close a glove box door cover panel of an automobile. As shown in fig. 1, an automotive glove box door/cover actuator 100 includes: the driving unit includes a housing 10, a driving motor 20, a worm shaft 30, a first rotating shaft 40, a worm wheel 50, a driving unit 60, a pushing member 70, and a return spring 80.

The housing 10 is provided with a slide groove 11 and a fixing member 12. The chute 11 is used to mount the push member 70 and provide a sliding track for the push member 70. The securing member 12 is used to mount the automotive glove box door/cover actuator 100 on an automotive glove box door. The housing 10 is configured to mount the driving motor 20, the worm 30, the first rotating shaft 40, the worm wheel 50, the driving unit 60, the pushing member 70, and the return spring 80, and to ensure the assembling stability thereof.

The driving motor 20 is mounted on the housing 10. The worm 30 is mounted on a motor shaft of the driving motor 20. The first rotating shaft 40 is fixed on the housing 10, and specifically, the first rotating shaft 40 is a rivet, and the rivet is riveted on the housing 10. The worm wheel 50 is sleeved on the first rotating shaft 40 and can rotate around the first rotating shaft 40, the worm wheel 50 is meshed with the worm 30, and the worm 30 rotates to drive the worm wheel 50 to rotate around the first rotating shaft 40. The return spring 80 is sleeved on the first rotating shaft 40 and is located between the shell 10 and the worm wheel 50, one end of the return spring 80 is fixed on the shell 10, the other end of the return spring 80 is fixed on the worm wheel 50, and when the glove door cover plate is in a closed state, the return spring 80 is in a free state. When the glove door cover plate is opened, the worm wheel 50 rotates, and the return spring 80 generates torque. In the present embodiment, the return spring 80 is a torsion spring.

A pushing member 70 is installed in the chute 11, the pushing member 70 being slidable in the chute 11 for pushing the opening and closing of the glove door cover. The pushing member 70 is always in contact with the glove door panel during the opening and closing of the glove door panel.

The driving unit 60 is in transmission connection with the worm wheel 50, and the worm wheel 50 rotates to provide driving force for the driving unit 60. The driving unit 60 is drivingly connected to the pushing member 70 for driving the pushing member 70 to slide within the chute 11, thereby opening and closing the glove door panel.

In the present embodiment, as shown in fig. 1, 2, and 3, the driving unit 60 includes: a gear 61, a second rotating shaft 62 and a sector gear 63.

The gear 61 is sleeved on the first rotating shaft 40 and fixed on the worm wheel 50, the gear 61 can rotate around the first rotating shaft 40, and the worm wheel 50 rotates, so that the gear 61 rotates simultaneously. Specifically, the gear 61 and the worm gear 50 are provided as a coaxial double gear, and the coaxial double gear is sleeved on the first rotating shaft 40 to rotate around the first rotating shaft 40.

The second rotating shaft 62 is fixed on the casing 10, and specifically, the second rotating shaft 62 is a rivet, and the rivet is riveted on the casing 10.

The rotation center of the sector gear 63 is sleeved on the second rotating shaft 62 and can rotate around the second rotating shaft 62. The center of rotation of the sector gear 63 is the angular vertex at which the central angle of the sector is located. The arcuate edge of the sector gear 63 is divided into two portions, one portion being provided as gear teeth 631 and the other portion being provided as a slide rail 632. The gear teeth 631 of the sector gear 63 mesh with the gear 61, and rotation of the gear 61 causes rotation of the sector gear 63. The slide rail 632 forms an angle with the gear surface of the sector gear 63, one end of the slide rail 632 close to the gear teeth 631 (i.e. the end of the rail 6321 in fig. 3) is far away from the housing 10, and one end of the slide rail 632 far away from the gear teeth (i.e. the end of the rail 6322 in fig. 3) is close to the housing 10. The height difference between the two ends of the slide rail 632 is the same as the sliding distance of the pushing member 70 in the sliding slot 11, and the height difference between the two ends of the slide rail 632 is the height difference between the rail 6321 and the rail 6322 as shown in fig. 3. The design of the sector gear 63 enables the rotation torque of the sector gear 63 to be converted into the thrust of the pushing member 70 along the direction of the slide rail 11, so that the force conversion is realized, and the effects of small torque input and large thrust output are achieved.

As shown in fig. 4, the pushing member 70 is provided with a slider 71 matched with the slide rail 632 for sliding on the slide rail 632, and specifically, the slider 71 is cylindrical. When the glove door cover is in the closed position, the slider 71 is located at one end of the slide rail 632 near the gear teeth 631, i.e., on the rail 6321 as shown in fig. 3.

Specifically, the rails 6321 and 6322 at both end portions of the slide rail 632 are parallel to the gear face of the sector gear 63, and the rail 6322 at the end of the slide rail 632 away from the gear teeth 631 of the sector gear 63 is bent in the direction of the central angle side of the sector gear 63, specifically, the angle between the rail 6322 and the rail 6323 is 80 ° to 120 °. The design enables the sliding block 71 to be better supported by the tracks 6321 and 6322 when the glove door cover is in the open or closed state. The rail 6342 prevents the pushing member 70 from continuously sliding in the sliding slot 11 toward the glove door cover plate when the sliding block 71 continues to slide on the rail 6342 after the pushing member 70 completely pushes the glove door cover plate open, so as to prevent the sliding distance of the pushing member 70 in the sliding slot 11 from being too large to push the glove door cover plate to be damaged, and to prevent the sliding block 71 from easily disengaging from the rail 632.

In the present embodiment, as shown in fig. 5, the sliding chute 11 includes a first sliding chute 111 and a second sliding chute 112, and the width of the first sliding chute 111 is greater than the width of the second sliding chute 112, i.e. a step surface 113 is formed at the connection between the first sliding chute 111 and the second sliding chute 112. The pushing member 70 is provided with a first stopper 72 for limiting the sliding distance of the pushing member within the chute 11 when the pushing member 70 slides within the chute to open the glove door panel. That is, when the glove door cover is in the fully opened state, the first stopper 72 just contacts the step surface 113 between the first sliding groove 111 and the second sliding groove 112. The first stopper 72 further prevents the pushing member 70 from sliding within the chute 11 a large distance to push the glove door panel bad, while preventing the slider 71 from disengaging from the track 632.

In this embodiment, the automotive glove box door/cover actuator 100 further includes a bumper 90, the bumper 90 being mounted to the housing 10 on a side opposite the arcuate edge of the sector gear 63. The fan-shaped gear is used for playing a role in buffering and reducing noise when the fan-shaped gear rotates.

In this embodiment, the end 76 of the pushing member 70 that contacts the glove door panel is planar. When the pushing member 70 pushes the glove door cover plate, the force bearing area is large, and the glove door cover plate cannot be damaged. Specifically, a plane of one end of the pushing member 70 contacting the glove door panel is provided only on one side of the slider 71, and a reinforcing rib 78 is provided between the plane and the pushing member.

Procedure for opening glove door cover plate by the automotive glove door/cover actuator 100: the driving motor 20 is powered through the terminals 101 and 102, the driving motor 20 is rotated, the driving motor 20 rotates to drive the worm 30 to rotate, the worm 30 rotates to drive the worm wheel 50 to rotate, the return spring 80 generates torque, the gear 61 is coaxial with the worm wheel 50 and fixed on the worm wheel 50, therefore, the gear 61 rotates along with the worm wheel 50, the gear 61 drives the sector gear 63 to rotate, the sector gear 63 rotates to enable the sliding rail 632 to rotate, the sliding block 71 on the pushing member 70 slides on the sliding rail 632 (slides from the rail 6321 to the rail 6322), and the pushing member 70 slides in the sliding groove 11 of the shell 10 towards the glove door cover plate, so that the glove door cover plate is opened. After the driving motor 20 is powered on, the rotation signal provided for the driving motor 20 enables the driving motor 20 to drive the worm wheel 50 to rotate by an angle, which just enables the sliding block 71 to slide from the track 6321 to the track 6322 of the sliding rail 632, and after the glove door cover is opened, the driving motor 20 stops rotating.

Procedure for closing glove door cover plate by the automotive glove door/cover actuator 100: when the glove door cover plate needs to be closed, the driving motor 20 is powered off, the return spring 80 drives the worm wheel 50 to rotate reversely under the elastic force action of the return spring 80, the worm wheel 50 drives the gear 61 to rotate reversely, the gear 61 rotates reversely to drive the sector gear 63 to rotate reversely, so that the sliding block 71 on the pushing member 70 slides reversely relative to the sliding rail 632, the pushing member 70 slides in the sliding groove 11 of the shell 10 in the direction opposite to the glove door cover plate, and the glove door cover plate is closed. The reverse rotation angle of the worm wheel 50 driven by the return spring 80 is the same as the rotation angle when the glove door cover plate is opened, so that after the glove door cover plate is closed, the slider 71 stays at the initial position, namely the track 6321, and the return spring 80 is in a free state.

< example two >

The same structures in this embodiment as those in the first embodiment are given the same reference numerals, and the same descriptions are omitted.

The difference between the present embodiment and the first embodiment is: as shown in fig. 6, the driving unit 60 includes: the screw 64 is sleeved on the first rotating shaft 40 and can rotate around the first rotating shaft 40, the screw 64 is fixed on the worm gear 50, and the worm gear 50 rotates to drive the screw 64 to rotate. The pushing member 70 is provided with a screw hole 73 and a slide hole 74. The threaded hole 73 is matched with the thread of the screw rod 64, one end of the screw rod 61, which is far away from the worm wheel 50, is arranged in the threaded hole 73 and is connected with the pushing component 70 through the threaded hole 73, and the screw rod 64 rotates the belt to enable the pushing component 70 to move on the screw rod 64 so as to slide in the sliding groove 11 and further open or close the glove door cover plate.

The sliding hole 74 is used to provide a telescopic space for the screw 64, and the depth of the sliding hole is at least greater than the sum of the sliding distance of the pushing member 70 and the distance that the screw 64 extends into the sliding hole 74 when the glove door cover is in the closed state.

The housing 10 is adapted in a state of ensuring its assembling stability according to the specific design of the driving motor 20, the worm shaft 30, the first rotating shaft 40, the worm wheel 50, the driving unit 60, the push member 70 and the return spring 80.

In this embodiment, the pushing member 70 is provided with a second stopper 75, when the pushing member 70 completely opens the glove door cover, the second stopper 75 just contacts with the step surface 113 between the first sliding slot 111 and the second sliding slot 112, so as to prevent the pushing member 70 from continuously sliding towards the glove door cover in the sliding slot 11, avoid damaging the glove door cover, and simultaneously avoid the pushing member 70 from disengaging from the screw 64.

In this embodiment, the end 77 of the pushing member 70 that contacts the glove door panel is flat. When the pushing member 70 pushes the glove door cover plate, the force bearing area is large, and the glove door cover plate cannot be damaged.

Procedure for opening glove door cover plate by the automotive glove door/cover actuator 100: the power is supplied to the driving motor 20 through the terminals 101 and 102, so that the driving motor 20 rotates, the driving motor 20 rotates to drive the worm 30 to rotate, the worm 30 rotates to drive the worm wheel 50 to rotate, the return spring 80 generates a torque, the screw 64 rotates along with the worm wheel 50, the screw 64 rotates to enable the pushing member 70 to be screwed out relative to the screw 64, and therefore the pushing member 70 slides in the sliding groove 11 of the shell 10 towards the glove door cover plate to open the glove door cover plate. After the driving motor 20 supplies power, the rotation signal provided for the driving motor 20 enables the driving motor 20 to drive the worm gear 50 to rotate by an angle, the distance that the pushing member 70 moves is just enabled to open the glove door cover plate, that is, the second limiting block 75 is just enabled to move to contact with the step surface 113 of the sliding chute 11, and the driving motor 20 stops rotating.

Procedure for closing glove door cover plate by the automotive glove door/cover actuator 100: when the glove door cover plate needs to be closed, the driving motor 20 is powered off, the return spring 80 drives the worm gear 50 to rotate reversely under the elastic force of the return spring 80, the screw rod 64 rotates reversely along with the worm gear 50, the screw rod 64 rotates to enable the pushing member 70 to be screwed in relative to the screw rod 64, and therefore the pushing member 70 slides in the sliding groove 11 of the shell 10 towards the opposite direction of the glove door cover plate to close the glove door cover plate. The return spring 80 drives the worm wheel 50 to rotate reversely to the same angle as the rotating angle when the glove door cover plate is opened, so that after the glove door cover plate is closed, the sliding block 71 stays at the initial position, and the return spring 80 is in a free state.
