DETAILED DESCRIPTION

[0034] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0035] An armrest 4 provided in an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] like Figure 1 As shown, according to some embodiments of the present invention, the armrest 4 includes a first gear 1, which is suitable for connecting to a driving device 3; and also includes a first connecting rod 2, the first end of the first connecting rod 2 is connected to the first gear 1, and the second end of the first connecting rod 2 is suitable for connecting to the armrest 4; the first gear 1 can be driven to rotate by the driving device 3 to drive the first connecting rod 2 to rotate, thereby driving the armrest 4 to move in the height direction.

[0037] Specifically, the armrest 4 in the related art is raised and lowered manually, which is cumbersome and provides a poor user experience. Therefore, a drive device 3, i.e., an electric drive assembly, is provided to drive the first gear 1 to rotate, so that the first connecting rod 2 can drive the armrest 4 to move in the vehicle height direction. The first connecting rod 2 needs to be connected to a fixed part in other positions of the vehicle or seat so that the first connecting rod 2 can be supported. The first connecting rod 2 can be connected to other fixed parts via a rotating shaft. At this time, the first connecting rod 2 can rotate along the rotating shaft without generating translation. In some other embodiments, the drive device 3 can also be a manual drive device 3, and the specific structure of the drive device 3 is not limited here.

[0038] According to some embodiments of the present invention, when the armrest 4 is applied to a vehicle seat, two groups of the first connecting rod 2, the first gear 1, and the driving device 3 are each provided, and each group of the first connecting rod 2 supports one armrest 4. This arrangement allows for individual control of the raising and lowering of a single armrest 4 and a relatively simple structure. In some other embodiments, the first connecting rod 2 and the first gear 1 can also be applied to the armrest 4 of an armrest box. At the same time, two first connecting rods 2 and two first gears 1 can also be provided for the armrest 4 on the armrest box. The two first connecting rods 2 can be provided in front of, behind, or to the left and right of the armrest 4 of the armrest box. In some other embodiments, the number of the first connecting rods 2, the first gear 1, and the driving device 3 can also be adjusted according to actual usage habits and spatial position.

[0039] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first gear 1 is directly connected to the first end of the first connecting rod 2, and the first gear 1 is driven by the driving device 3 to rotate counterclockwise to drive the first connecting rod 2 to rotate clockwise; or the first gear 1 is driven by the driving device 3 to rotate clockwise to drive the first connecting rod 2 to rotate counterclockwise.

[0040] Specifically, taking the left armrest 4 of the vehicle's main driver's seat as an example, when viewed from the left to the right, the first gear 1 can rotate counterclockwise under the drive of the drive device 3. At this time, the first connecting rod 2 rotates clockwise under the drive of the first gear 1. At this time, the second end of the first connecting rod 2 moves upward, thereby driving the armrest 4 upward. Under the same viewing angle, when the first gear 1 rotates clockwise under the drive of the drive device 3, the first connecting rod 2 rotates counterclockwise under the drive of the first gear 1. At this time, the second end of the first connecting rod 2 moves downward, thereby driving the armrest 4 downward. The connection method between the first connecting rod 2 and the first gear 1 is not limited, as long as it can satisfy the requirement that the first gear 1 drives the first connecting rod 2 to rotate when the first connecting rod 2 rotates, thereby causing the first connecting rod 2 to drive the armrest 4 to move up and down.

[0041] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the armrest 4 further includes: a second gear 5, the second gear 5 is engaged with the first gear 1, the second gear 5 is connected to the driving device 3, and the second gear 5 can be driven to rotate by the driving device 3 to drive the first gear 1 to rotate.

[0042] Specifically, the driving device 3 is a driving motor, which can directly drive the second gear 5 to rotate clockwise or counterclockwise. Taking the left armrest 4 of the vehicle's main driver's seat as an example, when looking from the left side to the right side of the vehicle, the second gear 5 rotates in a clockwise direction under the rotation of the driving motor, so that the second gear 5 drives the first gear 1 to rotate in a counterclockwise direction, thereby causing the armrest 4 to rise; when the second gear 5 rotates in a counterclockwise direction under the rotation of the driving motor, the second gear 5 drives the first gear 1 to rotate in a clockwise direction, thereby causing the armrest 4 to fall.

[0043] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the armrest 4 further includes a traction device 7, which is connected to the first gear 1, and the traction device 7 is connected to the first connecting rod 2, so that the traction device 7 moves under the drive of the first gear 1, thereby driving the first connecting rod 2 to rotate.

[0044] Specifically, the traction device 7 can be set as a flexible traction device 7. By connecting the traction device 7 to the first connecting rod 2 and the first gear 1, the first connecting rod 2 does not need to be directly connected to the first gear 1. The rotation of the first gear 1 can be transmitted to the first connecting rod 2 through the traction device 7, so that the position setting of the first connecting rod 2 is more flexible, and the rotation ratio of the first connecting rod 2 and the first gear 1 can be adjusted through the traction device 7. The flexible traction device 7 has the advantage of low noise, which can reduce the noise during the lifting and lowering operation of the armrest 4 and improve the user experience.

[0045] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the armrest 4 further includes: a first shaft 11 , the first shaft 11 is connected to the first gear 1 , and the traction device 7 is connected to the first shaft 11 .

[0046] Specifically, one end of the first shaft 11 is connected to the center of the first gear 1. When the first gear 1 rotates, the first shaft 11 also rotates axially, thereby driving the traction device 7 to move, and the traction device 7 drives the first end of the first connecting rod 2 to move, thereby rotating the first connecting rod 2.

[0047] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the armrest 4 further includes a third gear 6 , which is engaged with the second gear 5 .

[0048] Specifically, the second gear 5 is a driving gear, the first gear 1 and the third gear 6 are driven gears, and the third gear 6 is also engaged with the second gear 5. When the second gear 5 rotates, it drives the first gear 1 and the third gear 6 to rotate, wherein the first gear 1 and the third gear 6 have the same rotation direction. The third gear 6 is also connected to the first connecting rod 2. The first connecting rod 2 is connected to the first gear 1 and the third gear 6 at the same time, so that the first connecting rod 2 is more stable and has better support during operation.

[0049] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first end of the traction device 7 is connected to the first gear 1, the second end of the traction device 7 is connected to the third gear 6, and the traction device 7 is fixedly connected to the first end of the first connecting rod 2 to move under the rotation of the first gear 1 and the third gear 6, thereby driving the first connecting rod 2 to rotate.

[0050] Specifically, when the first gear 1, the second gear 5 and the third gear 6 are provided at the same time, the rotation of the second gear 5 drives the first gear 1 and the third gear 6 to rotate in the same direction, the first end of the traction device 7 is connected to the first gear 1, and the second end of the traction device 7 is connected to the third gear 6, so that the traction device 7 is driven by the first gear 1 and the third gear 6 at the same time and moves more stably, and can better provide the first connecting rod 2 with the power of rotation.

[0051] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the armrest 4 includes a first shaft 11 and a second shaft 61, the first shaft 11 is connected to the first gear 1, and the first end of the traction device 7 is connected to the first shaft 11; the second shaft 61 is connected to the third gear 6, and the second end of the traction device 7 is connected to the second shaft 61.

[0052] Specifically, by connecting the traction device 7 to the first shaft 11 and the second shaft 61 respectively, the rotation of the first gear 1 and the third gear 6 is simultaneously transmitted to the first connecting rod 2 through the traction device 7, so that the power of the first connecting rod 2 is more sufficient and the rotation is more stable.

[0053] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the handrail 4 further includes a fixed shaft 8 , and the traction device 7 is connected to the fixed shaft 8 .

[0054] Specifically, still taking the left-side armrest 4 of the driver's seat as an example, from a left-to-right perspective, in one embodiment of the present invention, the traction device 7 is configured as a traction rope, one end of which is wound around the first shaft 11 and the other end is wound around the second shaft 61. When the first gear 1 and the third gear 6 rotate counterclockwise under the drive of the second gear 5, the traction rope moves counterclockwise along the axis of the rope. The first end of the first connecting rod 2 is fixedly connected to the traction rope. When the traction rope moves, the first end of the first connecting rod 2 moves, thereby driving the first connecting rod 2 to move in a clockwise direction. At this time, the second end of the first connecting rod 2 moves upward, and the armrest 4 moves upward. When the traction rope moves clockwise under the drive of the first gear 1 and the third gear 6, the first connecting rod 2 moves counterclockwise, and the second end of the first connecting rod 2 moves downward, thereby driving the armrest 4 to move downward. The fixed shaft 8 is a shaft with a fixed position. The traction rope can be bent under the action of the fixed shaft 8 to change the extension direction of the traction rope. In an embodiment of the present invention, three fixed shafts 8 are provided. The three fixed shafts 8 place the first end and the second end of the traction rope on the same side of the entire traction rope, so that the adjacent first gear 1 and the third gear 6 can drive the traction rope to move.

[0055] like Figure 1 and Figure 2 As shown, in some other embodiments, two drive devices 3 can be set, and the two drive devices 3 can independently control the rotation of the first gear 1 and the third gear 6. At this time, the second gear 5 is no longer needed to drive the first gear 1 and the third gear 6 to rotate, and more sufficient power can be provided to the first gear 1 and the third gear 6. Setting two drive devices 3 does not limit the positions of the first end and the second end of the traction rope. At this time, the number of fixed shafts 8 can be adjusted according to actual conditions.

[0056] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the armrest 4 further includes a fixed bracket 9 , on which a first sliding groove 91 is provided. When the first connecting rod 2 rotates, the first end of the first connecting rod 2 moves along the first sliding groove 91 .

[0057] Specifically, the first connecting rod 2 needs to be fixed by the fixed bracket 9 in order to rotate stably. A first sliding groove 91 is set on the fixed bracket 9. The extension direction of the first sliding groove 91 can be set to the horizontal direction. At this time, the first end of the first connecting rod 2 can move horizontally along the first sliding groove 91, and the second end of the first connecting rod 2 rises or falls at the same time; the first sliding groove 91 can also be set to be inclined at a certain angle to the horizontal direction, as long as it can satisfy the function of enabling the fixed bracket 9 to support the first connecting rod 2 while allowing the second end of the first bracket to support the armrest 4 to rise or fall.

[0058] like Figure 3 As shown, according to some embodiments of the present invention, the armrest 4 further includes a second connecting rod 21, a first end of the second connecting rod 21 being connected to the armrest 4, a second end of the second connecting rod 21 being connected to the fixed bracket 9, and the second connecting rod 21 being connected to the first connecting rod 2 via an axle pin 22. Rotation of the first connecting rod 2 can drive rotation of the second connecting rod 21. The fixed bracket 9 has an "I"-shaped cross-section in a direction perpendicular to the direction in which the first chute 91 extends. Two first chute 91 are provided, and are arranged on both sides of the "I" shape. At least a portion of the first end of the first connecting rod 2 is respectively placed in the two first chute 91, thereby further stabilizing the connection between the first connecting rod 2 and the fixed bracket 9.

[0059] According to some embodiments of the present invention, the rotation direction of the second connecting rod 21 is opposite to the rotation direction of the first connecting rod 2 .

[0060] Specifically, the first link 2 and the second link 21 are connected by an axle pin 22. The first link 2 and the second link 21 are arranged crosswise, allowing the first link 2 to rotate relative to the axle pin 22, and the second link 21 to rotate relative to the axle pin 22. The first link 2 and the second link 21 rotate in opposite directions, thereby jointly supporting the handrail 4. When the first gear 1 and the third gear 6 rotate counterclockwise, the traction rope rotates counterclockwise along the axis, thereby driving the second end of the second link 21 toward the first end of the first link 2. At this time, the second end of the first link 2 and the first end of the second link 21 also approach each other, so that the first link 2 and the second link 21 jointly drive the handrail 4 upward. When the first gear 1 and the third gear 6 rotate clockwise, the traction rope rotates clockwise along the axis, thereby driving the second end of the second link 21 away from the first end of the first link 2. At this time, the second end of the first link 2 and the first end of the second link 21 also move away from each other, so that the first link 2 and the second link 21 jointly drive the handrail 4 downward.

[0061] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the axle pin 22 is disposed at the center point of the first connecting rod 2 and / or the second connecting rod 21 .

[0062] Specifically, different locations of the axle pin 22 will result in different rising or falling distances of the armrest 4 when the first link 2 and the second link 21 rotate at the same angle. Therefore, when the axle pin 22 is set at the center point of the first link 2 and the second link 21, when the rotational force is applied to the first link 2 and the second link 21, the second gear 5 and the drive device 3 will not generate excessive driving force, and the rising and falling distances of the armrest 4 will not be too large. If the rising and falling distances of the armrest 4 need to be set to be larger, the axle pin 22 is set at a position close to the first end of the first link 2 and / or the second end of the second link 21. In this case, the drive device 3 needs to provide a larger force, and the distance the armrest 4 moves up and down will also be larger.

[0063] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the armrest 4 further includes a movable bracket 10, the armrest 4 is connected to the movable bracket 10, the second end of the first connecting rod 2 is connected to the movable bracket 10, and the first end of the second connecting rod 21 is connected to the movable bracket 10.

[0064] Specifically, due to the limited volume of the armrest 4, if the first connecting rod 2 and the second connecting rod 21 are directly connected to the armrest 4 at the same time, the connection may be unstable or the armrest 4 may move up and down unstably. At this time, a movable bracket 10 needs to be set, and the second end of the first connecting rod 2 and the first end of the second connecting rod 21 are both connected to the movable bracket 10, so that the movable bracket 10 drives the armrest 4 to move up and down.

[0065] like Figure 3 As shown, according to some embodiments of the present invention, a second sliding groove 101 is provided on the movable bracket 10 , and when the second connecting rod 21 rotates, the first end of the second connecting rod 21 rotates along the second sliding groove 101 .

[0066] Specifically, when the first link 2 and the second link 21 drive the movable bracket 10 to move up and down, the second end of the first link 2 is rotationally connected to the movable bracket 10, and the first end of the second link 21 is rotationally connected to the fixed bracket 9. The first end of the first link 2 and the fixed bracket 9 can slide relative to each other, and the second end of the second link 21 can slide relative to the movable bracket 10. A second chute 101 is provided on the second link 21. The second chute 101 and the first chute 91 extend in the same direction. The lengths of the second chute 101 and the first chute 91 need to match the distance the handrail 4 rises and falls. The longer the distance the handrail 4 rises and falls, the longer the chute length. The cross-section of the movable bracket 10 in a direction perpendicular to the extension direction of the second chute 101 is in the shape of an "I". Two second chute 101 are provided, and are arranged on both sides of the "I" shape. At least a portion of the first end of the second link 21 is respectively disposed in the two second chute 101, thereby further stabilizing the connection between the second link 21 and the movable bracket 10.

[0067] like Figure 4 As shown, according to some embodiments of the present invention, the armrest 4 is provided with a first limiting portion 41 , and the movable bracket 10 is provided with at least two limiting grooves 102 that can accommodate the first limiting portion 41 .

[0068] Specifically, in addition to being able to move up and down under the action of the first connecting rod 2 and the first gear 1, the armrest 4 can also move forward and backward or left and right along the front and rear direction of the vehicle. One end of the armrest 4 is rotatably connected to the movable bracket 10. When the armrest 4 needs to move forward and backward or left and right, the other end of the armrest 4 is lifted. At this time, one end of the armrest 4 and the movable bracket 10 rotate relative to each other, the first limiting portion 41 disengages from the limiting groove 102, and moves the position of the armrest 4. The armrest 4 moves from position A to position C via position B. After the armrest 4 is moved to the target position, the other end of the armrest 4 is lowered. At this time, the first limiting portion 41 on the armrest 4 is placed in another limiting groove 102 corresponding to the target position. Multiple limiting grooves 102 are arranged at intervals along the moving direction of the armrest 4. The number of limiting grooves 102 is set according to the requirement of the moving distance of the armrest 4, and the distance between two adjacent limiting grooves 102 can also be adjusted according to the requirement of the movement of the armrest 4.

[0069] In some other embodiments, two first limiting portions 41 may be provided, and the two first limiting portions 41 are provided on both sides of the armrest 4 in a direction perpendicular to the moving direction of the armrest 4. Correspondingly, two groups of limiting grooves 102 are provided on the movable bracket 10 on both sides of the armrest 4 in a direction perpendicular to the moving direction of the armrest 4, and the number of the two groups of limiting grooves 102 is equal. This arrangement can make the armrest 4 more stably fixed after movement.

[0070] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the armrest 4 is provided with a second limiting portion 42 , and the second limiting portion 42 can abut against at least a portion of the movable bracket 10 to place the armrest 4 in a preset position.

[0071] Specifically, when the armrest 4 needs to be fully opened and fixed to the target position, especially when the armrest 4 on the armrest box needs to be fully raised and fixed, a second limiter 42 is provided on the armrest 4. After the armrest 4 is raised, the second limiter 42 is placed on the edge of the movable bracket 10. At this time, since the armrest 4 is still rotatably connected to the movable bracket 10, the second limiter 42 will restrict the armrest 4 from further rotating relative to the movable bracket 10, thereby stabilizing the armrest 4 in the target position. The second limiter 42 can also be provided on both sides of the armrest 4, and the second limiters 42 on both sides can respectively abut against the movable bracket 10 to improve the stability of the armrest 4 when it is fixed in the target position.

[0072] Another embodiment of the present invention provides a vehicle seat, comprising the armrest 4 described above.

[0073] Another embodiment of the present invention provides a vehicle armrest box, comprising the armrest 4 described above.

[0074] Another embodiment of the present invention provides a vehicle, including the armrest 4 described above, or the vehicle seat described above, or the vehicle armrest box described above.
