[0038] Figure 1is a schematic cross-sectional view of a vehicle handle device according to an embodiment of the utility model, as shown Figure 1 As shown, and refer to Figure 2 The embodiment of the utility model provides a vehicle handle device 100 . The handle device 100 includes a guide rail 110 , a worm 120 , a rolling assembly 130 and a handle 140 .

[0039] The guide rail 110 is used to be fixedly connected to the roof 200 of the vehicle. The worm 120 is directly or indirectly connected to the roof 200, and the worm 120 extends along the length direction of the guide rail 110 and is spaced apart from the guide rail 110. The worm 120 is connected to an active power source. The rolling assembly 130 is configured to roll on the guide rail 110 under the drive of the worm 120. The handle 140 is fixedly connected to the rolling assembly 130.

[0040] In this embodiment, the handle device 100 can be arranged on the ceiling 200 on the upper side of the vehicle door, or on the ceiling 200 near the seat in the vehicle. Of course, the handle device 100 is not limited to being arranged on the ceiling 200, for example, it can also be arranged on the inner wall of the vehicle body, as long as it can provide an installation position for the guide rail 110 and the worm 120.

[0041] It should be noted that the roof 200 of the vehicle is a feature of the use environment of the present application, that is, the handle device 100 of the present application can be independently manufactured and sold without the roof 200.

[0042] Exemplarily, the guide rail 110 is fixedly mounted on the roof 200 and extends along the front-rear direction of the vehicle. Figure 1 The worm 120 is arranged parallel to and spaced from the guide rail 110, and the axis direction of the worm 120 is also the front-rear direction.

[0043] The rolling assembly 130 may be provided with a worm wheel matched with the worm 120. The worm 120 rotates under the driving of the source power, drives the rolling assembly 130 to roll on the guide rail 110, and drives the handle 140 to move.

[0044] For example, when the worm 120 rotates forward, the handle 140 can be driven to move forward, and when the worm 120 rotates reversely, the handle 140 can be driven to move backward. In other words, the handle 140 moves toward or away from the seat of the vehicle, thereby meeting the needs of passengers of different heights and different arm lengths for the handle 140, thereby improving the passenger experience.

[0045] In this embodiment, since the worm gear mechanism has a self-locking effect, when the movement of the handle 140 is not actively controlled, the positions of the rolling assembly 130 and the handle 140 can be locked to provide a firm support for the passenger.

[0046] On the other hand, since the rolling assembly 130 rolls on the guide rail 110, compared with sliding movement, the friction between the rolling assembly 130 and the guide rail 110 is lower, which can reduce the output requirements of the source power, and can reduce the noise generated during movement, thereby improving the user experience.

[0047] In some embodiments of the handle device of the present invention, Figure 1-2 As shown, the handle 140 is hinged to the rolling assembly 130 about an axis parallel to the worm 120 .

[0048] In this embodiment, taking the longitudinal direction of the guide rail 110 as the front-to-back direction, the handle 140 is hinged to the mounting seat 131 of the rolling assembly 130 around the axis extending front-to-back. That is, the handle 140 can rotate left and right. In this way, when the handle 140 is not in use, the handle 140 can be placed against the ceiling 200 or the inner wall of the vehicle to reduce space occupation. When the passenger uses the handle 140, the passenger can hold the handle 140 by pulling it outward away from the ceiling 200 or the inner wall of the vehicle.

[0049] In some embodiments of the handle device of the present invention, Figure 1-2 As shown, the rolling assembly 130 includes a mounting seat 131, a first worm gear (not shown in the figure) and a roller (not shown in the figure).

[0050] The first worm wheel is rotatably connected to the mounting seat 131 , and the first worm wheel is meshedly connected to the worm 120 . The roller is coaxially fixedly connected to the first worm wheel, and the wheel surface of the roller is rollingly connected to the guide rail 110 .

[0051] In this embodiment, the diameter of the first worm wheel can be smaller than, equal to, or larger than the diameter of the roller. The wheel surface of the roller can be a rough surface and fit in contact with the surface of the guide rail 110, or the wheel surface of the roller can contact the surface of the guide rail 110 to form a rolling friction force. When in use, the worm 120 drives the first worm wheel to rotate, and the roller rotates accordingly and rolls on the surface of the guide rail 110, thereby driving the mounting seat 131 and the handle 140 to move.

[0052] The handle device 100 in this embodiment can make full use of the high transmission ratio advantage of the worm gear 120 combination to reduce the moving speed of the handle 140, improve the positioning accuracy of the handle 140, or reduce the reduction ratio of the reducer of the motor 150. On the other hand, since the moving speed of the handle 140 is half of the linear speed of the wheel surface of the roller, the moving speed of the handle 140 can be further reduced, the positioning accuracy of the handle 140 can be improved, or the reduction ratio of the reducer of the motor 150 can be reduced.

[0053] In some embodiments of the handle device of the present invention, Figure 1-2As shown, the guide rail 110 includes a rack, the tooth surface of which faces the worm 120. The rolling assembly 130 includes a mounting seat 131 and a second worm gear 132.

[0054] The second worm gear 132 is rotatably connected to the mounting seat 131 . The second worm gear 132 is located between the worm 120 and the rack. The second worm gear 132 is meshed with the worm 120 and the rack.

[0055] In this embodiment, the worm 120 and the rack sandwich the second worm gear 132 in the middle, for example, the worm 120 is located at the upper end of the second worm gear 132, and the rack is located at the lower end of the second worm gear 132. When in use, the worm 120 drives the second worm gear 132 to rotate when it rotates, and the second worm gear 132 meshes and moves on the rack, thereby driving the mounting seat 131 and the handle 140 to move along the length direction of the rack.

[0056] Compared with the friction force that causes the roller to move on the surface of the guide rail 110, the meshing force that rolls along the rack can prevent the second worm gear 132 from slipping during the movement, thereby improving the movement and positioning accuracy. The meshing force that rolls along the rack can also improve the firmness of the connection of the rolling assembly 130. Through the dual limit of the worm 120 and the rack, the rolling assembly 130 is locked at the required position, and it is not easy to shake or move forward and backward even if the passenger pulls with great force.

[0057] The handle device 100 in this embodiment can make full use of the high transmission ratio advantage of the worm gear combination to reduce the moving speed of the handle 140, improve the positioning accuracy of the handle 140, or reduce the reduction ratio of the reducer of the motor 150. On the other hand, since the moving speed of the handle 140 is half of the linear speed of the wheel surface of the roller, the moving speed of the handle 140 can be further reduced, the positioning accuracy of the handle 140 can be improved, or the reduction ratio of the reducer of the motor 150 can be reduced.

[0058] In some embodiments of the handle device of the present invention, the source power is a motor 150 , and the motor 150 is directly fixedly connected to the ceiling 200 .

[0059] In some embodiments of the handle device of the present invention, Figure 2 As shown, the output shaft of the motor 150 is coaxially fixedly connected to the worm 120 .

[0060] This transmission method has a simple structure and high transmission efficiency.

[0061] In some embodiments of the handle device of the present invention, Figure 1 As shown, the output shaft of the motor 150 is drivingly connected to the worm 120 via a bevel gear mechanism 160 .

[0062] Specifically, a bevel gear can be provided at the end of the output shaft of the motor 150, and a matching bevel gear is also provided at the end of the corresponding worm 120, and the two bevel gears are meshed and connected to achieve power transmission. This technical solution facilitates the free setting of the position and angle of the motor 150 and effectively utilizes the space inside the vehicle. The transmission ratio of the output shaft of the motor relative to the worm 120 can be adjusted through the bevel gear mechanism 160, and the rolling movement speed of the handle 140 can be set within an ideal range.

[0063] In some embodiments of the handle device of the present invention, Figure 1-2 As shown, the handle device 100 further includes a guide rail bracket 170 , and the guide rail bracket 170 is fixedly connected to the guide rail 110 . The motor 150 is fixedly connected to the guide rail bracket 170 .

[0064] In this embodiment, the motor 150 is indirectly fixedly connected to the ceiling 200 through the guide rail bracket 170. In this way, the handle device 100 can be independent and modularized, and there is no need to set additional installation holes, installation seats and other installation structures for the motor 150 on the ceiling 200. It is only necessary to fix the guide rail 110 on the ceiling 200. In addition, the matching accuracy between the motor 150 and the worm 120 can be improved.

[0065] In some embodiments of the handle device of the present invention, Figure 1-2 As shown, the handle device 100 further includes two guide rail brackets 170 , and the two guide rail brackets 170 are respectively fixedly connected to the two ends of the guide rail 110 in the length direction.

[0066] The worm 120 is rotatably connected to two guide rail brackets 170 .

[0067] In this embodiment, the worm 120 is indirectly rotatably connected to the ceiling 200 through two guide rail brackets 170. In this way, the handle device 100 can be independent and modularized, and there is no need to set up an additional mounting bracket for the worm 120 on the ceiling 200. It is only necessary to fix the guide rail 110 on the ceiling 200. Specifically, the worm 120 can be connected to the guide rail bracket 170 through a bearing.

[0068] In some embodiments of the handle device of the present invention, Figure 1-2 As shown, there are two rolling assemblies 130 spaced apart along the length direction of the guide rail 110. One rolling assembly 130 is connected to each of the two ends of the U-shape of the handle 140.

[0069] In this way, a firm support can be provided for the handle 140 , and the handle 140 can be prevented from rotating around an axis in the vertical direction, thereby providing a firm support for the passenger.

[0070] In some embodiments of the handle device of the present invention, the handle device 100 further includes a control switch (not shown in the figure), which is disposed on the handle 140 and electrically connected to the source power.

[0071] In this embodiment, when using the handle 140 , the passenger can conveniently touch the control switch to control the handle 140 to move to a suitable position.

[0072] In some embodiments of the handle device of the present invention, the control switch includes three states, namely, an initial state, a first state, and a second state. When the control switch is in the first state, the motor 150 rotates forward, driving the handle 140 to move forward. When the control switch is in the second state, the motor 150 rotates reversely, driving the handle 140 to move backward.

[0073] In this embodiment, the initial state is that the motor 150 is not working.

[0074] There may be two control switches, one to trigger the first state and the other to trigger the second state. In this way, the user can conveniently and quickly control the handle 140 to move closer or farther away and stop at a suitable position.
