Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0052] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0053] In the description of this application, it should be noted that if the terms "upper", "lower", "inner", "outer", etc. appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the disclosed product is in use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0054] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0055] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0056] As disclosed in the background section, existing automotive armrest boxes are generally opened by pressing buttons on both sides of the armrest box near the driver and passenger seats. However, since the buttons on both sides of the armrest box are far from the rear passengers, it is inconvenient for the rear passengers to open the armrest box.

[0057] Please refer to Figures 1-5. The handrail device 10 provided in the embodiments of this application includes a housing 100, a lid 200, a first locking member 300, and a first unlocking member 400. The lid 200 is rotatably disposed on the housing 100 to open or close the housing 100. The lid 200 has a first side and a second side opposite to each other. The first locking member 300 is movably disposed on the first side of the lid 200 to lock the lid 200 to the housing 100. The first unlocking member 400 is disposed on the third side of the lid 200 other than the first and second sides. The first unlocking member 400 is used to drive the first locking member 300 to move so that the lid 200 is unlocked from the housing 100.

[0058] The rotation axis of the lid 200 is located on the first or second side of the box body 100. During the rotation of the lid 200 around the rotation axis, the box body 100 is opened or closed. Figure 1 shows a partial structure of the box body 100, which has openings for taking out and putting in items.

[0059] The direction of movement of the first locking member 300 is perpendicular to the line connecting the first side and the second side. During the movement of the first locking member 300, the first locking member 300 can lock the lid 200 to the body 100. When the armrest device 10 is installed in the car, the third side where the first unlocking member 400 is provided is positioned close to the rear passenger. The first unlocking member 400 can drive the first locking member 300 to move, so that the lid 200 is unlocked from the body 100.

[0060] The first locking member 300 may include a locking tongue, a lock hole on the housing 100, and a through hole on the cover 200. When the locking tongue passes through the through hole and engages with the lock hole, the first locking member 300 locks the cover 200 to the housing 100.

[0061] In its initial state, the armrest device 10 has the cover 200 closing the box body 100, and the first locking member 300 locking the cover 200 to the box body 100. When a rear passenger needs to open the box body 100, the first unlocking member 400 on the third side of the cover 200 near the rear seat moves the first locking member 300, thereby unlocking the cover 200 from the box body 100. At this time, the rotation axis is located on the second side of the cover 200, and the cover 200 can be rotated around the rotation axis, thereby opening the box body 100. By setting the first unlocking member 400 on the third side of the cover 200 near the rear seat, the convenience of the rear passenger to open the armrest box can be improved.

[0062] In this embodiment, the handrail device 10 further includes a transmission component 500, which is movably disposed on the box cover 200. The first unlocking member 400 is used to drive the transmission component 500 to move. The transmission component 500 is used to drive the first locking member 300 to move during the movement, so that the box cover 200 and the box body 100 are unlocked.

[0063] The transmission assembly 500 is disposed between the first unlocking member 400 and the first locking member 300. When the first unlocking member 400 drives the transmission assembly 500 to move, the transmission assembly 500 can drive the first locking member 300 to move until the cover 200 and the box body 100 are unlocked.

[0064] In some embodiments, the transmission assembly 500 includes a connecting rod 510 and a first transmission member 520 connected to each other. The connecting rod 510 is movably disposed on the cover 200, and the first transmission member 520 is rotatably disposed on the cover 200. The first unlocking member 400 is used to drive the connecting rod 510 to move, the connecting rod 510 is used to drive the first transmission member 520 to rotate, and the first transmission member 520 is used to drive the first locking member 300 to move during the rotation.

[0065] The connecting rod 510 extends along the direction of the rotation axis, and the direction of movement of the connecting rod 510 is consistent with the direction of the rotation axis; a bushing 524 is provided in the middle of the first transmission member 520, and the bushing 524 is fixed to the cover 200 by screws. The first transmission member 520 can rotate relative to the bushing 524, which helps to improve the stability of the first transmission member 520.

[0066] By setting the rotation center of the first transmission component 520 in the middle, the rotation arm of the first transmission component 520 is smaller during the unlocking process, thereby reducing the tolerance.

[0067] When the first unlocking component 400 drives the connecting rod 510 to move, the connecting rod 510 drives the first transmission component 520 to rotate clockwise. During the clockwise rotation, the first transmission component 520 drives the first locking component 300 to move until the first locking component 300 releases the lock on the cover 200 and the box body 100.

[0068] It is understandable that the first transmission component 520 can drive the first locking component 300 to move in the opposite direction during the process of rotating counterclockwise, until the first locking component 300 locks the cover 200 to the box body 100.

[0069] Of course, in some other embodiments, when the first transmission member 520 rotates counterclockwise, the first locking member 300 releases the locking of the lid 200 and the box body 100; while when the first transmission member 520 rotates clockwise, the first locking member 300 locks the lid 200 to the box body 100.

[0070] In the embodiments of this application, the first transmission member 520 is described as rotating clockwise to unlock the first locking member 300.

[0071] If the position of the first unlocking member 400 needs to be adjusted, it can be achieved by adjusting the length of the first transmission member 520 in the direction perpendicular to the rotation axis; at the same time, the length of the connecting rod 510 can also be adjusted, and the mechanism design has a large degree of freedom.

[0072] Please refer to Figures 5 and 6. In some embodiments, one of the first transmission member 520 and the connecting rod 510 is provided with a first mating hole 521, and the other is provided with a first mating part 511 that mates with the first mating hole 521, so that the connecting rod 510 drives the first transmission member 520 to rotate during movement.

[0073] In an optional embodiment, the first transmission member 520 is provided with a first mating hole 521, and the connecting rod 510 is provided with a first mating part 511 that mates with the first mating hole 521.

[0074] The first mating hole 521 can be a waist-shaped hole or a strip-shaped hole, and the first mating part 511 can be a pin. The pin passes through the first mating hole 521. During the movement of the connecting rod 510, the first mating part 511 can move within the first mating hole 521, thereby driving the first transmission member 520 to rotate.

[0075] Please refer to Figures 2 and 7-9. In some embodiments, the first locking member 300 is provided with a boss 310, and the first transmission member 520 is used to abut and push the boss 310 during rotation so as to move the first locking member 300.

[0076] In the initial state, there is a certain gap between the first transmission member 520 and the boss 310. When the first unlocking member 400 drives the connecting rod 510 to move, the first transmission member 520 rotates and supports and pushes the boss 310 during the rotation, so that the first locking member 300 moves.

[0077] In some embodiments, the cover 200 is provided with a first limiting part 220 and a first resetting member 230. The first resetting member 230 abuts against the first transmission member 520 to drive the first transmission member 520 to reset to abut against the first limiting part 220.

[0078] The first reset member 230 may be a torsion spring, and the first transmission member 520 may be provided with a hooking part 522, with one end of the torsion spring hooked onto the hooking part 522; or, the first transmission member 520 may be provided with a slot, with one end of the torsion spring hooked into the slot. In other embodiments, the first reset member 230 may also be an elastic component such as a spring, tension spring, or spring sheet.

[0079] When the first transmission member 520 is no longer subjected to external force, the first reset member 230 can drive the first transmission member 520 to reset, that is, the first reset member 230 drives the first transmission member 520 to rotate in the counterclockwise direction. During the process of rotating in the counterclockwise direction, the first transmission member 520 abuts against the first limiting part 220. The first limiting part 220 can limit the rotation angle of the first transmission member 520 from being too large.

[0080] In an optional embodiment, referring to FIG6, an abutment portion 523 is provided on the outer side surface of the first transmission member 520, and the abutment portion 523 abuts against the first limiting portion 220 during the resetting process of the first transmission member 520.

[0081] Please refer to Figures 2 and 10. In some embodiments, the lid 200 is provided with a second unlocking member 280 and a third unlocking member 290 on the first and second sides, respectively. The second unlocking member 280 is used to move the first locking member 300 so as to unlock the lid 200 from the box body 100. The handrail device also includes a second locking member 210, which is movably disposed on the second side of the lid 200 to lock the lid 200 to the box body 100. The third unlocking member 290 is used to move the second locking member 210 so as to unlock the lid 200 from the box body 100.

[0082] The first unlocking component 400, the second unlocking component 280, and the third unlocking component 290 can all be buttons. By pressing the button, the first locking component 300 or the second locking component 210 can be moved, thereby unlocking the lid 200 from the body 100.

[0083] The lid 200 is movably provided with a first movable plate 201 and a second movable plate 202, and the moving direction of the first movable plate 201 and the second movable plate 202 is the direction of the line connecting the first side and the second side.

[0084] The first locking member 300 has a first strip-shaped hole, the extension direction of which forms an angle with the moving direction of the first locking member 300. The first movable plate 201 has a first axle pin that engages with the first strip-shaped hole. The second unlocking member 280 can drive the first movable plate 201 to move towards the second side of the lid 200. Simultaneously, the first axle pin moves within the first strip-shaped hole, causing the first locking member 300 to move towards the third side of the lid 200, thereby releasing the lock between the lid 200 and the box body 100. It should be understood that the first strip-shaped hole and the first axle pin can be interchanged; for example, the first movable plate 201 can have a first strip-shaped hole, and the first locking member 300 can have a first axle pin that engages with the first strip-shaped hole.

[0085] The second locking member 210 has a second slotted hole, the extension direction of which forms an angle with the moving direction of the second locking member 210. The second movable plate 202 has a second pin that engages with the second slotted hole. The third unlocking member 290 can move the second movable plate 202 toward the first side of the lid 200. Simultaneously, the second pin moves within the second slotted hole, causing the second locking member 210 to move toward the third side of the lid 200, thereby releasing the lock between the lid 200 and the box body 100. It should be understood that the second slotted hole and the second pin can also be interchanged; for example, the second movable plate 202 can have a second slotted hole, and the second locking member 210 can have a second pin that engages with the second slotted hole.

[0086] To ensure that the unlocking function of the other two unlocking components is canceled when any one of the first unlocking component 400, the second unlocking component 280, and the third unlocking component 290 is used to unlock the lid, so as to prevent the lid 200 from being unlocked on the first and second sides at the same time, a protective component 203 is rotatably provided on the lid. The protective component 203 is located between the first movable plate 201 and the second movable plate 202, and the protective component 203 is provided with a slot 2031 for the first movable plate 201 to be partially inserted.

[0087] When the first unlocking member 400 is pressed, causing the first locking member 300 to move toward the third side of the cover 200, the pin moves in the first slot, causing the first movable plate 201 to move away from the second unlocking member 280. The first movable plate 201 is partially engaged in the slot 2031, and the protective member 203 cannot rotate counterclockwise. The second movable plate 202 abuts against the protective member 203. At this time, pressing the second unlocking member 280 can no longer move the first movable plate 201, and pressing the third unlocking member 290 can no longer move the second movable plate 202.

[0088] When the second unlocking member 280 is pressed, causing the first movable plate 201 to move toward the second side of the lid 200, the first locking member 300 releases the lock on the lid 200 and the box body 100. Part of the first movable plate 201 is engaged in the slot 2031, the protective member 203 cannot rotate counterclockwise, and the second movable plate 202 abuts against the protective member 203. The first locking member 300 moves under the action of the first movable plate 201. At this time, pressing the first unlocking member 400 can no longer move the first locking member 300, and the third unlocking member 290 cannot push the second movable plate 202 to move.

[0089] Similarly, when the third unlocking member 290 is pressed, causing the second movable plate 202 to move towards the first side of the lid 200, the second locking member 210 releases the lock between the lid 200 and the box body 100. Simultaneously, the second movable plate 202 causes the protective member 203 to rotate counterclockwise, making the protective member 203 abut against the first movable plate 201. At this time, pressing the second unlocking member 280 cannot move the first movable plate 201. Furthermore, due to the engagement between the first slot on the first locking member 300 and the pin on the first movable plate 201, the first unlocking member 400 cannot move the first locking member 300.

[0090] In some embodiments, the handrail device 10 further includes a third locking member 600 and a second transmission member 700. The third locking member 600 is movably disposed on the cover 200 to lock the cover 200 to the box body 100. The second transmission member 700 is rotatably disposed on the cover 200 and is connected to both the first locking member 300 and the third locking member 600. During the movement of the first locking member 300, the second transmission member 700 is driven to rotate, and during the rotation of the second transmission member 700, the third locking member 600 is driven to move.

[0091] The direction of movement of the third locking member 600 is consistent with the direction of rotation axis. Optionally, the direction of movement of the third locking member 600 is opposite to the direction of movement of the first locking member 300. The way the third locking member 600 locks the lid 200 to the box body 100 is roughly the same as the way the first locking member 300 locks the lid 200 to the box body 100, which will not be described in detail here.

[0092] Since the first side needs to provide a pivot for the rotation of the lid 200 when it is opened from the second side, the first locking member 300 and the third locking member 600 usually need to appear in pairs to provide two locking points on the third and fourth sides, thus realizing the pivot function. Similarly, in addition to the locking point provided by the second locking member 210, the second side also needs a fourth locking member that is nearly symmetrical with the third locking member 600 in the direction of the line connecting the first and second sides, to provide another locking point.

[0093] The rotational connection between the second transmission component 700 and the box cover 200 is roughly the same as that between the first transmission component 520 and the box cover 200, and will not be described again here.

[0094] When the first unlocking member 400 drives the connecting rod 510 to move, the connecting rod 510 drives the first transmission member 520 to rotate clockwise. During the clockwise rotation, the first transmission member 520 drives the first locking member 300 to move until the first locking member 300 releases the lock on the lid 200 and the body 100. At the same time, during the movement, the first locking member 300 drives the second transmission member 700 to rotate clockwise. During the clockwise rotation, the second transmission member 700 drives the third locking member 600 to move until the third locking member 600 releases the lock on the lid 200 and the body 100.

[0095] It is understandable that the second transmission component 700 can drive the third locking component 600 to move in the opposite direction during the counterclockwise rotation until the third locking component 600 locks the cover 200 to the box body 100.

[0096] A second limiting part 240 may also be provided on the cover 200. The second transmission member 700 abuts against the second limiting part 240 during the process of rotating in the counterclockwise direction. The second limiting part 240 can limit the rotation angle of the second transmission member 700 from being too large.

[0097] The first locking member 300, the second locking member 210, and the third locking member 600 can all be selected as rods, and the extension direction of the first locking member 300, the second locking member 210, and the third locking member 600 is consistent with the extension direction of the connecting rod 510; in other embodiments, the first locking member 300, the second locking member 210, and the third locking member 600 can be other shapes, and there is no limitation on this.

[0098] It should be noted that the key transmission segment of the handrail device 10 is from the connection between the first transmission member 520 and the connecting rod 510 to the connection between the first locking member 300 and the second transmission member 700. Since the length of this segment is relatively small, the tolerances and functional stability between the parts can be better controlled. Furthermore, when the handrail device 10 is in its initial state, the gap between the first transmission member 520 and the boss 310 can be set to be small, and the distance between the boss 310 and the second transmission member 700 can be set to be short, thereby reducing the dimensional tolerance between the second transmission member 700 and the first locking member 300.

[0099] When the handrail device 10 is in its initial state, the gaps between the first unlocking member 400 and the connecting rod 510, the gaps between the connecting rod 510 and the first transmission member 520 along the rotation axis, and the gaps between the first transmission member 520 and the first limiting part 220 are all zero. This ensures a rapid response of the entire mechanism during the transmission of external force. Since the gap between the first transmission member 520 and the boss 310 is set to be small, there is almost no free travel when pressing the first unlocking member 400, thereby enhancing the stability and comfort of the mechanism.

[0100] In some embodiments, referring to Figures 4 and 11, one of the second transmission member 700 and the third locking member 600 is provided with a second mating hole 710, and the other is provided with a second mating portion 610 that mates with the second mating hole 710; one of the second transmission member 700 and the first locking member 300 is provided with a third mating hole 720, and the other is provided with a third mating portion 320 that mates with the third mating hole 720.

[0101] In an optional embodiment, the second transmission member 700 is provided with a second mating hole 710 and a third mating hole 720, the third locking member 600 is provided with a second mating part 610 that mates with the second mating hole 710, and the first locking member 300 is provided with a third mating part 320 that mates with the third mating hole 720.

[0102] Both the second mating hole 710 and the third mating hole 720 can be selected as waist-shaped holes or strip-shaped holes. The second mating part 610 is a pin, which passes through the second mating hole 710. Alternatively, when the third locking member 600 is a rod, one end of the third locking member 600 is bent to form the second mating part 610 and passes through the second mating hole 710. The third mating part 320 can be selected as a pin, which passes through the third mating hole 720.

[0103] During the movement of the connecting rod 510, the second mating part 610 can move within the second mating hole 710, and the third mating part 320 can move within the third mating hole 720, thereby facilitating the rotation of the second transmission member 700.

[0104] Please refer to Figure 12. In some embodiments, two first limiting structures 250 are provided opposite to each other on the cover 200 along the line connecting the first side and the second side, and two first guide members 512 are provided opposite to each other on the connecting rod 510. The two first limiting structures 250 limit the two first guide members 512 respectively.

[0105] Two first limiting structures 250 are located on both sides of the connecting rod 510 along the line connecting the first side and the second side. Two first guide members 512 are disposed on the two sides of the connecting rod 510 along the line connecting the first side and the second side. The two first limiting structures 250 abut against the two first guide members 512 respectively, so that the connecting rod 510 is not easy to be displaced in the direction perpendicular to the connecting rod 510.

[0106] Optionally, two first limiting structures 250 arranged opposite each other along the direction of the vertical link 510 constitute a group of first limiting structures 250. Multiple groups of first limiting structures 250 can be arranged along the direction of the link 510. Correspondingly, two first guide members 512 arranged opposite each other along the direction of the vertical link 510 constitute a group of first guide members 512. Multiple groups of first guide members 512 can be arranged along the direction of the link 510. Multiple groups of first limiting structures 250 correspond one-to-one with multiple groups of first guide members 512. Two first limiting structures 250 in each group of first limiting structures 250 abut against two first guide members 512 in the corresponding group of first guide members 512.

[0107] Please refer to Figure 13. In some embodiments, two second limiting structures 260 are provided opposite to each other on the lid 200 along the line connecting the first side and the second side, and two second guide members 330 are provided opposite to each other on the first locking member 300 along the line connecting the first side and the second side. The two second limiting structures 260 abut against the two second guide members 330 respectively.

[0108] Two second limiting structures 260 are located on both sides of the first locking member 300 along the line connecting the first side and the second side, and two second guide members 330 are disposed on the two sides of the first locking member 300 along the line connecting the first side and the second side. The two second limiting structures 260 abut against the two second guide members 330 respectively, so that the first locking member 300 is not easily displaced along the line connecting the first side and the second side or in a direction perpendicular to the cover 200.

[0109] Optionally, two second limiting structures 260 arranged opposite each other along the line connecting the first side and the second side constitute a group of second limiting structures 260. Multiple groups of second limiting structures 260 can be arranged along the direction of the rotation axis. Correspondingly, two second guide members 330 arranged opposite each other along the line connecting the first side and the second side constitute a group of second guide members 330. Multiple groups of second guide members 330 can be arranged along the direction of the rotation axis. The multiple groups of second limiting structures 260 correspond one-to-one with the multiple groups of second guide members 330. Two second limiting structures 260 in each group of second limiting structures 260 abut against two second guide members 330 in the corresponding group of second guide members 330.

[0110] Both the first guide member 512 and the second guide member 330 can be selected as ribs. Similarly, ribs can also be provided on the second locking member 210 and the third locking member 600. A limiting structure that abuts against the rib is provided on the cover 200. This will not be described in detail.

[0111] It is understood that in other embodiments, the limiting of the connecting rod 510, the first locking member 300, the second locking member 210, or the third locking member 600 is not limited to the cooperation of the above-mentioned ribs and limiting structures. As long as the connecting rod 510, the first locking member 300, the second locking member 210, and the third locking member 600 are not easily displaced along the line connecting the first side and the second side or in a direction perpendicular to the cover 200, the limiting of the connecting rod 510, the first locking member 300, the second locking member 210, or the third locking member 600 can also be achieved by the sliding cooperation of the slider and the slide groove.

[0112] Referring to Figure 14, in some embodiments, the handrail device 10 further includes a drive member 800 and a sensor 900 electrically connected to the drive member 800. The sensor 900 is used to sense the first unlocking member 400. The drive member 800 is connected to the link 510 to drive the link 510 to move.

[0113] The sensor 900 can be a Hall sensor. The sensor 900 can be set on the cover 200 near the first unlocking member 400. When the first unlocking member 400 is a button, pressing the button will cause the button to contact or approach the sensor 900. The sensor 900 will receive the button pressing signal and send a drive signal to the drive member 800. After receiving the drive signal, the drive member 800 will drive the connecting rod 510 to move.

[0114] The drive unit 800 can be a combination of a motor and a gear. The connecting rod 510 is equipped with a rack that meshes with the gear. When the motor starts, it drives the gear to rotate, which in turn drives the connecting rod 510 to move through the rack.

[0115] In some other embodiments, as shown in FIG15, the driving member 800 may also be connected to the first locking member 300, and the driving member 800 directly drives the first locking member 300 to move after receiving the driving signal.

[0116] Referring to Figure 16, in some embodiments, the transmission assembly 500 includes a pulling member 530, a first transmission member 520, and at least two third transmission members 540. The first transmission member 520 and the at least two third transmission members 540 are rotatably mounted on the cover 200. The pulling member 530 connects the at least two third transmission members 540 to transmit the rotation of the third transmission members 540. A first unlocking member 400 is used to push one of the third transmission members 540 to rotate, and the other third transmission member 540 is used to drive the first transmission member 520 to rotate during rotation. The first transmission member 520 is used to drive the first locking member 300 to move during rotation. This embodiment is described with two third transmission members 540.

[0117] The pulling member 530 can be a pull rope or a pull belt. When the first unlocking member 400 pushes one of the third transmission members 540 to rotate, the third transmission member 540 pulls the other third transmission member 540 to rotate via the pull rope or pull belt, thereby driving the first transmission member 520 to rotate. When the transmission assembly 500 includes the pulling member 530, it occupies less space, has a higher degree of freedom in structural arrangement, and has greater applicability.

[0118] The first transmission component 520, the second transmission component 700, and the third transmission component 540 can all be selected as turntables. The rotational connection method between the third transmission component 540 and the box cover 200 is roughly the same as that between the first transmission component 520 and the box cover 200, and will not be described in detail here.

[0119] In some embodiments, as shown in FIG2, a second reset member 270 is provided on the cover 200. The second reset member 270 is connected to the first locking member 300 to drive the first locking member 300 to reset.

[0120] The second reset member 270 may be a torsion spring, one end of which is attached to the first locking member 300; or, the first locking member 300 may have a slot in which one end of the torsion spring is engaged. In other embodiments, the second reset member 270 may also be an elastic component such as a spring, tension spring, or sheet spring.

[0121] When the first transmission component 520 is no longer subjected to external force, the first reset component 230 can drive the first transmission component 520 to reset, and at the same time the second reset component 270 can drive the first locking component 300 to reset. During the reset process, the first locking component 300 drives the third locking component 600 to reset through the second transmission component 700, until the cover 200 is locked on the box body 100.

[0122] Figure 17 shows the handrail device 10 applied to a car. Of course, in other embodiments, the handrail device 10 can also be applied to other means of transportation such as ships and aircraft, and there is no limitation thereto.

[0123] The working principle of the handrail device 10 provided in this application embodiment is as follows: In the initial state, the cover 200 closes the box body 100, and the first locking member 300, the second locking member 210, and the third locking member 600 together lock the cover 200 to the box body 100. When a rear passenger needs to open the box body 100, pressing the first unlocking member 400 moves the connecting rod 510. The connecting rod 510 moves the first locking member 300 through the first transmission member 520, and the first locking member 300 moves. The first locking member 300 moves the third locking member 600 through the second transmission member 700 until the lid 200 is unlocked from the body 100. When the first unlocking member 400 is no longer pressed, the first transmission member 520 resets under the action of the first reset member 230, thereby driving the connecting rod 510 to reset. The first locking member 300 resets under the action of the second reset member 270, and drives the third locking member 600 to reset through the second transmission member 700, until the lid 200 is locked to the body 100.

[0124] In summary, this application provides an armrest device 10, which includes a housing 100, a cover 200, a first locking member 300, and a first unlocking member 400. When a rear passenger needs to open the housing 100, the first unlocking member 400 on the cover 200 near the rear seat moves the first locking member 300, thereby unlocking the cover 200 from the housing 100. At this time, the cover 200 can be rotated to open the housing 100. By setting the first unlocking member 400 on the third side of the cover 200 near the rear seat, the convenience for rear passengers to open the armrest box can be improved.

[0125] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
