Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a table top assembly, an armrest box device and a vehicle. Background Art

[0002] In related art, a tabletop assembly used in a vehicle typically includes a stowage member and a tabletop. The stowage member's lower end is pivotally mounted to the armrest box, and the tabletop is pivotally mounted to its upper end. The stowage member can be flipped upright or flat, allowing the tabletop to be stored within the armrest box or exposed outside. The tabletop can rotate relative to the stowage member to switch between a vertical and horizontal position. When the user needs to use the tabletop, they first flip the stowage member to the vertical position, then flip the tabletop to the horizontal position.

[0003] In order to keep the stowage unit in an upright position and prevent it from accidentally rotating and causing the table to become unstable, a locking member is usually installed on the armrest box, and the locking member is used to constrain the stowage unit in an upright position. When the user does not need to use the table, the table is first flipped to a vertical position, and then the locking member is unlocked by pressing the unlock button to release the stowage unit, allowing the stowage unit to return to a freely rotatable state. The stowage unit is then flipped flat to allow the table to be stored in the armrest box. It can be seen that the number of steps required to store the table makes the table assembly inconvenient to use. Summary of the Invention

[0019] In one embodiment, the table top unit includes a support member and a table top movably provided on the support member, the table top is rotatably mounted on the unfolding and retracting member through the support member, and the pushing surface and the limiting surface are provided on the support member.

[0020] In one embodiment, the table top unit is further provided with a positioning long hole extending circumferentially along the third axis, and the unfolding and retracting piece is provided with a positioning shaft inserted into the positioning long hole, and in the upright position, the positioning shaft abuts one end surface of the positioning long hole; in the horizontal position, the positioning shaft abuts the other end surface of the positioning long hole.

[0021] In one embodiment, the stowing member is provided with a supporting boss, and the table unit abuts against an upper side of the supporting boss in the horizontal position.

[0022] In one embodiment, one of the mounting seat and the limiting end is provided with a limiting groove, and the other is provided with a limiting protrusion, and the limiting protrusion can be inserted into the limiting groove to achieve locking, or withdrawn from the limiting groove to achieve unlocking.

[0023] In one embodiment, the unfolding and retracting member is provided with a mounting channel, the locking member is provided in the mounting channel, and the driven end and the limiting end are respectively exposed at two end openings of the mounting channel.

[0024] In one embodiment, the stowage member includes a first bracket and a second bracket connected to each other, the first bracket and the second bracket jointly define the installation channel, and the first axis is located in one of the first bracket and the second bracket.

[0025] In one embodiment, the lower end of the stowing member is rotatably mounted on the mounting seat around a second axis, and the table unit is mounted on the upper end, and the second axis intersects the first axis.

[0026] In one embodiment, the mounting seat is provided with a rotation space, the lower end of the unfolding and retracting member is rotatably connected to the opposite side walls of the rotation space, the top opening edge of the rotation space is provided with a limiting groove, and the locking member is provided with a limiting protrusion, and the limiting protrusion can be inserted into the limiting groove from the rotation space to achieve locking, or withdraw from the limiting groove to achieve unlocking.

[0030] The present invention also provides a vehicle, comprising the aforementioned table top assembly or armrest box device.

[0031] In the technical solution of the present invention, since the locking member follows the rotation of the table panel unit and can switch between the locked position and the unlocked position when the table panel unit switches between the upright position and the horizontal position, the position switching of the locking member is linked to the position switching of the table panel unit, thereby making the freedom of movement of the stowage member on the mounting seat linked to the horizontal table operation and the vertical table operation of the table panel unit. In this way, whether the stowage member is constrained in the exposed position or can be moved away from the exposed position, the user does not need to lock and unlock the stowage member, but only needs to use the horizontal table operation or the vertical table operation of the table panel unit. That is, at least the operation of pressing the unlock button when folding the table panel can be omitted, thereby saving the user the operating steps when using the table panel assembly, thereby improving the convenience of using the table panel assembly.

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0060] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0061] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0062] The present invention provides a tabletop assembly that improves its ease of use. Application scenarios for the tabletop assembly provided by embodiments of the present invention include, but are not limited to, vehicles, aircraft, and electric massage chairs. For ease of description, the following explanation will be based on a vehicle as an example.

[0063] See also Figures 1 to 3 In one embodiment of the present invention, the table top assembly includes a mounting base 230, an unfolding and retracting piece 300, a locking piece 400 and a table top unit 100. The unfolding and retracting piece 300 is movably mounted on the mounting base 230 and has a storage position and a revealing position; the locking piece 400 is movably provided on one of the unfolding and retracting piece 300 and the mounting base 230, and can be connected to or released from the limit with the other one to have corresponding locking position and unlocking position. The locking piece 400 in the locking position can constrain the unfolding and retracting piece 300 to the revealing position; the table top unit 100 is rotatably mounted on the unfolding and retracting piece 300 and has an upright position and a horizontal position.

[0064] See also Figure 1 Optionally, the tabletop unit 100 includes a support member 120 and a tabletop 110, and the tabletop 110 is rotatably mounted on the stowage member 300 via the support member 120. Figure 1 The stowage member 300 is shown in the stowed position, and the support member 120 and the table top 110 are in the upright position. At this time, the table top assembly can be stowed in the box 210 , for example, in the armrest box 200 . Figure 2 The stowage member 300 is shown in the exposed position, and the support member 120 and the table top 110 are in the upright position. At this time, the table top assembly can be exposed to the outside, for example, outside the armrest box 200 . Figure 3 The display and storage member 300 is shown in the exposed position, and the support member 120 and the table top 110 are in the horizontal position. At this time, the table top assembly can allow users to place items on it, so as to complete work, dining or games with the help of the table top 110.

[0065] The application scenarios of the armrest box 200 include, but are not limited to, a secondary instrument panel and a seat assembly, or it can be independently installed in the vehicle interior, which is not specifically limited in this application. When used in a secondary instrument panel, the armrest cover 220 on the armrest box 200, when closed, provides a support for the driver's arms and elbows while effectively concealing the table assembly within the armrest box 200.

[0066] In order to make the table 110 closer to the passengers for easier use, please refer to Figure 3 and Figure 12Optionally, the table top 110 can be moved on the support 120 to have a recovery position and a use position. The sliding movement of the table top 110 on the support 120 can be achieved by the cooperation of the guide rail 140 and the slider. Specifically, the table top 110 can be used normally by the passengers in the vehicle when in the use position, for example, using the table top 110 for office work, games or dining activities. When the table top 110 is in the recovery position, it can mean that it has been stored and hidden in other components, for example, it is stored in the armrest box 200 and is not exposed, or it can mean that it has not been stored and hidden, but is just ready to be further stored and hidden. The table top assembly in this embodiment belongs to the second case, that is, the table top 110 in the recovery position is still exposed to the outside, and the table top 110 in the recovery position may still allow the user to place items on it. Figure 3 The table top 110 is shown in the retracted position. Figure 12 The table top 110 is shown in the use position due to sliding to the right. It can be understood that the table top 110 is more ergonomic in the use position than in the retracted position. That is, the retracted position is a relative concept and is another position different from the use position.

[0067] Of course, in other embodiments, the support member 120 may not be provided, and the table top 110 may be directly connected to the stowage member 300 .

[0068] In order to increase the usable area of the table top 110 without significantly increasing the storage size of the table top 110, please refer to Figure 12 and Figure 13 Optionally, at least two table tops 110 are provided, and the at least two table tops 110 can slide or flip relative to each other, so that the multiple table tops 110 can be spread out when needed and can be retracted and stacked when not needed. Of course, in other embodiments, the table top 110 can also be provided as one.

[0069] Specifically, the table top assembly in this embodiment includes two table tops 110, and the two table tops 110 are connected by two hinge structures 130 and can be stacked (see Figure 12 ) and expanded state (see Figure 13 Of course, the number of table tops 110 and hinge structures 130 is not limited thereto. In other embodiments, three or more table tops 110 may be provided, or two adjacent table tops 110 may be connected by one hinge structure 130, or by three or more hinge structures 130.

[0070] In this embodiment, one of the two table tops 110 is movably connected to the support 120, and the other is not directly connected to the support 120. In this case, the recovery position refers to the two table tops 110 being moved as a whole to the leftmost position in the figure (see Figure 3 ), regardless of whether the two table tops 110 are in an unfolded state or a stacked state; the use position refers to the two table tops 110 being moved as a whole to the rightmost position in the figure (see Figures 12 to 15 ), it is not necessary to consider whether the two table tops 110 are in the unfolded state or the stacked state. That is, the meanings of the retracted position and the use position only characterize the relative position relationship between the table top 110 and the support member 120.

[0071] It is understood that the locking member 400 is movably disposed on one of the stowage member 300 and the mounting base 230 and can be engaged with the other in a limiting position (i.e., locked position) or released from the limiting position (i.e., unlocked position). In the locked position, the locking member 400 can restrain the stowage member 300 in the exposed position, thereby ensuring a more stable and reliable position of the table top 110 during use and preventing the table top 110 from becoming unstable due to accidental movement of the stowage member 300. When the locking member 400 is switched to the unlocked position, the stowage member 300 is no longer constrained and can move relative to the mounting base 230, thereby switching to the stowed position to conceal the table top unit 100.

[0072] Optionally, when the tabletop unit 100 switches between the upright position and the horizontal position, the locking member 400 can switch between the locked position and the unlocked position following the rotation of the tabletop unit 100, the locked position corresponding to the horizontal position, and the unlocked position corresponding to the upright position.

[0073] It should be noted that Figure 3 、 Figures 12 to 15 The table units 100 are all in the horizontal position, and the stowage elements 300 are all in the exposed position. Figure 2 The table unit 100 is shown in the upright position and the stowage element 300 is in the exposed position. Figure 3 、 Figure 12 or Figure 13 In either state, as long as the user lifts it upward to a vertical position, the locking member 400 will be switched to the unlocked position, so that the stowage member 300 is no longer constrained by the locking member 400 in the exposed position and can be rotated relative to the mounting base 230 to switch to the storage position.

[0074] Specifically, when the stowage piece 300 is in the exposed position, if the table unit 100 is switched from the vertical position to the horizontal position (i.e., horizontal table operation) by the user, it means that the user needs to use the table unit 100 and hopes that the table unit 100 can be stable and reliable. At this time, the locking piece 400 follows the rotation of the table unit 100 and enters the locking position to constrain the stowage piece 300 in the exposed position, thereby limiting the freedom of movement of the stowage piece 300 on the mounting base 230, and avoiding accidental movement of the stowage piece 300 causing instability of the table unit 100. When the stowage piece 300 is in the exposed position, if the table unit 100 is switched from the horizontal position to the vertical position (i.e., vertical table operation) by the user, it means that the user does not need to use the table unit 100 and hopes that the table unit 100 can be further stored. At this time, the locking piece 400 can switch from the locked position to the unlocked position following the rotation of the table unit 100, thereby releasing the restriction on the free movement of the stowage piece 300 on the mounting base 230, allowing the stowage piece 300 to switch from the exposed position to the stored position, thereby realizing further storage of the table unit 100.

[0075] In the technical solution of the present invention, when the tabletop unit 100 switches between the upright and horizontal positions, the locking member 400 rotates with the tabletop unit 100 and switches between the locked and unlocked positions. This allows the position switching of the locking member 400 to be linked to the position switching of the tabletop unit 100, thereby enabling the free movement of the stowage member 300 on the mounting base 230 to be linked to the horizontal or vertical operation of the tabletop unit 100. In this way, whether the stowage member 300 is constrained in the exposed position or can be removed from the exposed position, the user does not need to lock or unlock the stowage member 300; instead, the user only needs to use the horizontal or vertical operation of the tabletop unit 100. In other words, at least the operation of pressing the unlock button when stowing the tabletop 110 can be eliminated, thereby reducing the number of steps the user needs to take when using the tabletop assembly, thereby improving the ease of use of the tabletop assembly.

[0076] See also Figure 5 and Figure 6 Optionally, the locking member 400 is rotatably provided on the stowage member 300 around the first axis. Specifically, the locking member 400 can move between the storage position and the exposure position together with the stowage member 300. When the stowage member 300 moves to the exposure position and the table unit 100 moves to the horizontal position, the locking member 400 can enter the locking position and be connected to the mounting seat 230 in a limiting manner. In this way, the structure is simple and easy to implement. Of course, in other embodiments, the locking member 400 can be rotatably provided on the mounting seat 230 and can be connected to the stowage member 300 in a limiting manner; or the locking member 400 can be translated along the first direction, wherein the first direction can be parallel to or intersecting with the rotation axis of the table unit 100.

[0077] Optionally, the first axis is provided at the middle of the locking member 400, and the locking member 400 has a driven end 401 and a limiting end 402 relative to each other, the driven end 401 is drivenly connected to the table panel unit 100, and the limiting end 402 is limitedly connected to or released from the mounting seat 230. That is, the locking member 400 has a seesaw structure, so the structure is simple and easy to implement. Of course, in other embodiments, the first axis can also be provided at one end of the locking member 400, the middle part of the locking member 400 can be limitedly connected to or released from the mounting seat 230, and the other end of the locking member 400 is drivenly connected to the table panel unit 100. For example, the first axis is provided at the lower end of the locking member 400, and the upper end of the locking member 400 is drivenly connected to the table panel unit 100.

[0078] See also Figure 5 and Figure 6 Optionally, the tabletop assembly further includes a resilient member 500, which connects the locking member 400 and the stowing member 300. During the process of the locking member 400 switching from the unlocked position to the locked position, the elastic potential energy of the resilient member 500 increases. Thus, by adding the resilient member 500, the locking member 400 is able to automatically rotate from the unlocked position to the locked position, and the locking member 400 can be maintained in the locked position without external forces, thereby ensuring that the stowing member 300 is effectively restrained in the exposed position. Of course, in other embodiments, the resilient member 500 may not be provided, or the resilient member 500 may be configured such that its elastic potential energy increases during the process of the locking member 400 switching from the locked position to the unlocked position.

[0079] Optionally, the resetting elastic member 500 is disposed between the first axis and the limiting end 402, and is positioned close to the limiting end 402. This further distances the resetting elastic member 500 from the first axis, thereby increasing the torque exerted on the locking member 400 and the spatial dimension of its telescopic deformation, thereby ensuring the effectiveness and sensitivity of its elastic force. Of course, in other embodiments, the resetting elastic member 500 may also be disposed between the first axis and the driven end 401.

[0080] See also Figure 5 and Figure 7 Optionally, the reset elastic member 500 is configured as a compression spring, and at least one of the locking member 400 and the deploying member 300 is provided with a spring insertion hole 403, into which the compression spring is inserted. In this embodiment, both the locking member 400 and the deploying member 300 are provided with spring insertion holes 403. Thus, the compression spring is installed through the spring insertion hole 403, which not only simplifies the structure and facilitates installation, but also provides an effective deformation guide for the compression spring. Of course, in other embodiments, the spring insertion hole 403 may not be provided. For example, a plug post may be provided, and the compression spring may be sleeved on the outer circumference of the plug post; alternatively, the reset elastic member 500 may be configured as a tension spring or other elastic structure.

[0081] See also Figure 7 and Figure 8 Optionally, the length direction of the locking member 400 extends in the up-down direction, the driven end 401 is located at the upper end of the locking member 400, and the table unit 100 rotates around a third axis parallel to the first axis. It should be noted that parallel means parallel or nearly parallel. In this way, the table unit 100 and the locking member 400 are both in a rotating form, and the rotation of the table unit 100 can be used to directly cause the locking member 400 to rotate, which is beneficial to simplify the structure of the table assembly. Of course, in other embodiments, the length direction of the locking member 400 can also extend in the front-to-back direction, the driven end 401 can be located at the front or rear end of the locking member 400, the first axis extends in the up-down direction, and the rotation axis of the table unit 100 extends in the front-to-back direction.

[0082] See also Figure 5 and Figure 9 Optionally, the driven end 401 is provided with a driven protrusion 410, and the table unit 100 is provided with a push surface 101 corresponding to the driven protrusion 410. The push surface 101 can push against the first side surface 411 of the driven protrusion 410 to cause the locking member 400 to switch from the unlocked position to the locked position. In this way, the locking member 400 is directly driven to rotate to the locked position by the push action of the table unit 100, which is simple in structure and easy to implement. Of course, in other embodiments, the driven protrusion 410 and the pushing surface 101 may not be provided. For example, a crank-connecting rod mechanism is added and connected between the table unit 100 and the locking member 400; or, a push-pull rod is added, and the two ends of the push-pull rod are respectively rotatably connected to the table unit 100 and the locking member 400. When the table unit 100 is flipped to the horizontal position, the locking member 400 is pulled by the push-pull rod, and when it is flipped to the upright position, the locking member 400 is pushed by the push-pull rod. That is, the unlocking or locking of the locking member 400 is driven by the table unit 100.

[0083] It should be noted that the pushing surface 101 pushing the driven protrusion 410 does not necessarily mean that the pushing continues throughout the entire stroke. It may also be that there is no contact in the first part of the stroke, and contact and pushing begin in the second part of the stroke.

[0084] See also Figure 5 and Figure 6In this embodiment, during the process of the table top unit 100 switching from the upright position to the horizontal position, the pushing surface 101 does not contact the driven protrusion 410 at first, and then contacts the driven protrusion 410 at a certain position, and then continues to push the driven protrusion 410 to switch the locking member 400 to the locked position. That is, in the exposed position, the rotation angle of the locking member 400 is smaller than the rotation angle of the table top unit 100. In this way, when the table top unit 100 rotates 90°, the locking member 400 only rotates a smaller angle, such as 3°, 5°, 10° or 15°, etc., thereby reducing the size of the rotation space 232 required for the locking member 400 and facilitating the miniaturization design of the table top assembly.

[0085] See also Figure 6 and Figure 9 Optionally, the tabletop unit 100 is further provided with a limiting surface 102 opposite to the pushing surface 101. When the tabletop unit 100 is in the upright position, the limiting surface 102 abuts against the second side surface 412 of the driven protrusion 410, and the first side surface 411 and the second side surface 412 are arranged opposite each other. In this way, assuming that the reset elastic member 500 fails in structure or is accidentally lost, resulting in the locking member 400 being unable to be driven by the elastic force to automatically reset to the unlocked position, in this case, the limiting surface 102 can also push against the driven protrusion 410 to rotate the locking member 400 toward the unlocked position, thereby ensuring that the linkage between the tabletop unit 100 and the locking member 400 is still effective, thereby ensuring that the locking member 400 can be promptly retreated to the unlocked position, allowing the unfolding member 300 to move freely and further stow the tabletop assembly. Of course, in other embodiments, the limiting surface 102 may not be provided.

[0086] See also Figure 9 Optionally, the tabletop unit 100 is provided with a clearance notch 103, and the two side surfaces of the clearance notch 103 opposite to each other in the circumferential direction of the third axis are respectively configured as a push surface 101 and a limiting surface 102. In this way, the structure is simple and easy to implement. Of course, in other embodiments, the clearance notch 103 may not be provided.

[0087] Optionally, the tabletop unit 100 includes a support member 120 and a tabletop 110 movably mounted on the support member 120. The tabletop 110 is rotatably mounted on the stowage member 300 via the support member 120, and the push surface 101 and the limiting surface 102 are disposed on the support member 120. In this way, the tabletop 110 can be moved on the support member 120 to have a recovery position and a use position, allowing the tabletop 110 to be closer to the occupant for easier use. Secondly, the clearance notch 103, the positioning slot 104, and the rotating structure of the tabletop unit 100 are all disposed on the support member 120, which helps to simplify the structure of the tabletop 110.

[0088] See also Figure 5 and Figure 6Optionally, the tabletop unit 100 further includes a positioning slot 104 extending circumferentially along the third axis. The display unit 300 includes a positioning shaft 340 inserted into the positioning slot 104. In the upright position, the positioning shaft 340 abuts one end surface of the positioning slot 104; in the horizontal position, the positioning shaft 340 abuts the other end surface of the positioning slot 104. In other words, the positioning shaft 340 and the positioning slot 104 cooperate to define two extreme positions within the tabletop unit 100's rotational travel. This provides a simple and easily implemented structure.

[0089] In order to improve the structural stability of the table unit 100 in the horizontal position, please refer to Figure 5 and Figure 7 Optionally, the display and storage member 300 is provided with a support boss 330, and the tabletop unit 100 rests on the upper side of the support boss 330 in the horizontal position. In this way, the support boss 330 is used to provide additional support for the tabletop unit 100, which can improve the structural stability of the tabletop unit 100. Even if a heavy object is pressed on the tabletop unit 100, the tabletop unit 100 will not accidentally tilt downward from the horizontal position. Secondly, in the embodiment in which the positioning long hole 104 and the positioning shaft 340 are provided, the additional support boss 330 can also reduce the pressure on the positioning shaft 340 in the horizontal position, which is beneficial to increase the service life of the positioning shaft 340. Of course, in other embodiments, the support boss 330 may not be provided.

[0090] See also Figure 5 and Figure 6 Optionally, one of the mounting base 230 and the limiting end 402 is provided with a limiting groove 231, and the other is provided with a limiting protrusion 420. The limiting protrusion 420 can be inserted into the limiting groove 231 to lock, or removed from the limiting groove 231 to unlock. In this way, the limiting protrusion 420 cooperates with the limiting groove 231 to lock or unlock the locking member 400 and the stowing member 300, resulting in a simple and easy-to-implement structure. Of course, in other embodiments, the limiting protrusion 420 can be provided on both the mounting base 230 and the limiting end 402.

[0091] See also Figure 5 and Figure 6 Optionally, the deploying and retracting member 300 is provided with a mounting channel 301, and the locking member 400 is disposed within the mounting channel 301, with the driven end 401 and the limiting end 402 respectively exposed at the two end openings of the mounting channel 301. In this manner, the mounting channel 301 protects the locking member 400 and the resetting elastic member 500, preventing foreign objects from interfering with the movement of the locking member 400. Of course, in other embodiments, the mounting channel 301 may not be provided.

[0092] Please also refer to Figure 7Optionally, the stowage member 300 includes a first bracket 310 and a second bracket 320 connected to each other. The first bracket 310 and the second bracket 320 together define a mounting channel 301, and the first axis is located between one of the first bracket 310 and the second bracket 320. This facilitates the manufacture of the stowage member 300 to form the mounting channel 301 and the assembly of the locking member 400 on the stowage member 300. Optionally, the first bracket 310 and the second bracket 320 are connected by a first fastener 302, which includes but is not limited to a screw or a rivet.

[0093] See also Figure 7 and Figure 8 Optionally, the first bracket 310 is provided with a slot structure, and the second bracket 320 is configured as a plate-like structure and covers the slot of the slot structure to enclose the installation channel 301. The lower end of the first bracket 310 is rotatably connected to the mounting seat 230, and the upper end is rotatably connected to the support member 120. The locking member 400 is mounted on the second bracket 320 via a first rotating shaft 430, and the axis of the first rotating shaft 430 is the first axis. In this way, the structure is simple and easy to implement. The materials of the first bracket 310 and the second bracket 320 can be configured to be different, for example, the first bracket 310 is metal and the second bracket 320 is plastic. In this way, the structural strength of the first bracket 310 can be made stronger, which is conducive to improving the connection strength and installation reliability of the display and storage member 300 and the support member 120 and the mounting seat 230.

[0094] See also Figure 5 and Figure 7 Optionally, a support boss 330 is provided at the upper end of the first bracket 310 and above and to the side of the mounting channel 301. A first buffer pad 331 is also provided on the upper side of the support boss 330, and the lower surface of the table top unit 100 abuts against the first buffer pad 331. In this way, the first buffer pad 331 can act as a vibration dampener, preventing the table top unit 100 from directly colliding with the support boss 330 and producing abnormal noise.

[0095] Specifically, in this embodiment, a limiting groove 231 is provided on the mounting base 230, and a limiting protrusion 420 is provided on the limiting end 402. In the exposed position, when the locking member 400 is only acted upon by the elastic force of the return elastic member 500 and not by the push of the table unit 100, the locking member 400 can remain in the unlocked position. In other words, the limiting protrusion 420 remains in a position out of the limiting groove 231, allowing the stowing member 300 to be moved from the exposed position. In the exposed position, when the locking member 400 is pushed into the locked position by the push of the table unit 100, the limiting protrusion 420 is inserted into the limiting groove 231, and the stowing member 300 is restrained in the exposed position. In other words, when the user flips the tabletop unit 100 upward from the horizontal position to the upright position, the pushing surface 101 gradually moves away from the driven protrusion 410, so that the driven end 401 is no longer pushed by the tabletop unit 100. The locking member 400 rotates toward the unlocked position under the release of the elastic potential energy of the reset elastic member 500, so that the limiting protrusion 420 can automatically disengage the limiting groove 231, and the unfolding and retracting member 300 is unlocked. In this way, the unlocking action of the unfolding and retracting member 300 is linked to the upward action of the tabletop unit 100, which can save the user's operating steps and improve the convenience of use.

[0096] See also Figure 6 and Figure 7 Optionally, the limiting protrusion 420 is formed separately from the main structure of the locking member 400 and connected via a second fastener 404, which includes but is not limited to screws or rivets. In this way, the limiting protrusion 420 can be made of a better or more wear-resistant material, such as metal or self-lubricating plastic steel, to increase its service life. Of course, in other embodiments, the limiting protrusion 420 and the driven protrusion 410 can also be integrally formed with the main structure of the locking member 400.

[0097] See also Figure 8 and Figure 9 Optionally, the lower end of the stowage member 300 is pivotally mounted on the mounting base 230 about a second axis, with the tabletop unit 100 mounted on the upper end, with the second axis intersecting the first axis. In this embodiment, the second axis extends in the left-right direction. This provides a simple and easily implemented structure. Of course, in other embodiments, the stowage member 300 can also be slidably mounted on the mounting base 230 in the up-down direction.

[0098] See also Figure 4 and Figure 10Optionally, the mounting base 230 is provided with a rotational space 232. The lower end of the stowing member 300 is pivotally connected to opposite side walls of the rotational space 232. A retaining groove 231 is provided at the top opening edge of the rotational space 232. The locking member 400 is provided with a retaining protrusion 420. The retaining protrusion 420 can be inserted from the rotational space 232 into the retaining groove 231 to lock the stowing member, or removed from the retaining groove 231 to unlock the stowing member 300. Thus, by providing the rotational space 232 and allowing the lower end of the stowing member 300 to pivotally connect to opposite side walls of the rotational space 232, the rotational smoothness and structural stability of the stowing member 300 can be improved. Furthermore, the placement of the retaining groove 231 at the opening edge of the rotational space 232 facilitates the manufacturing and forming of the retaining groove 231, and the structure is simple and easy to implement. Of course, in other embodiments, the rotational space 232 may be omitted.

[0099] It is worth mentioning that since the locking member 400 can be maintained in the unlocked position due to the action of the reset elastic member 500, that is, the limiting protrusion 420 can be maintained in the state of exiting the limiting groove 231, at this time, the stowage member 300 can not only be moved from the exposed position, but also can be rotated freely in the rotation space 232 without the problem of collision or friction between the limiting protrusion 420 and the inner wall surface of the rotation space 232. This not only improves the smoothness of the rotation of the stowage member 300, but also reduces the risk of damage to parts.

[0100] See also Figure 4 and Figure 11 Optionally, a second cushion 233 is provided on the bottom surface of the rotation space 232, and the stowage member 300 can abut against the second cushion 233 in the stowed position. In this way, the second cushion 233 can play a vibration-damping role, preventing the stowage member 300 from directly colliding with the mounting seat 230 and making abnormal noise.

The accommodating cavity 201 is provided in the box body 210 with the cavity opening facing upwards, and the opening and closing cover of the armrest cover 220 is provided at the cavity opening of the accommodating cavity 201. The armrest cover 220 is used for the driver's arms and elbows to lean on. In this embodiment, the table board assembly can be unfolded toward the right side for use by the passenger in the co-pilot seat. Figure 14 and Figure 15 The table top assembly is shown exposed and in an expanded state, with the armrest cover 220 covering the box body 210; Figure 16 The table top assembly is housed in the accommodating cavity 201 , and the armrest cover 220 covers the box body 210 ; Figure 17 for Figure 16 The structure shown is a schematic diagram after the armrest cover 220 is hidden.

[0103] Of course, in other embodiments, the armrest box device can also be applied to other products, for example, to rear seats. In this case, the armrest box device is located on the left or right side of the rear seat and is used as an armrest of the rear seat.

[0104] See also Figures 14 to 19 Optionally, the mounting base 230 of the table top assembly is mounted on the vehicle body floor and is at least partially located in the accommodating cavity 201. Specifically, Figure 17 The stowage member 300 is in a laid-down state (corresponding to the stowed position), and the support member 120 and the table top 110 are in an upright state (corresponding to the upright position), and the two table tops 110 are in a stacked state; Figure 18 and Figure 19 The stowage member 300 is in an upright state (corresponding to the exposed position), and the support member 120 and the table top 110 are in an upright state (corresponding to the upright position), and the two table tops 110 are in a stacked state; Figure 3 The stowage member 300 is in an upright state (corresponding to the exposed position), and the support member 120 and the table top 110 are in a flat state (corresponding to the horizontal position), and the two table tops 110 are in a stacked state and a retracted position; Figure 12 The stowage member 300 is in an upright state (corresponding to the exposed position), and the support member 120 and the table top 110 are in a flat state (corresponding to the horizontal position), and the two table tops 110 are in a stacked state and in use position.

[0105] In this way, when the stowage member 300 is in the laid-down state and the support member 120 is in the upright state, the stowage member 300 and the table top assembly can be accommodated in the accommodating cavity 201 (e.g., Figure 1 and Figure 17when the stowage member 300 is in an upright state, the table top 110 and the support member 120 are exposed; when the stowage member 300 is in an upright state and the support member 120 is in a flat state, the table top 110 is horizontally arranged.

[0106] Optionally, in this embodiment, the table top assembly includes a first table top 110 ( Figure 14 The table top 110 on the left) and the second table top 110 ( Figure 14 The first table top 110 is arranged on the support 120, and the second table top 110 is rotatably connected to the side of the first table top 110 away from the support 120 through the hinge structure 130. When the two table tops 110 are unfolded, the second table top 110 is located on the right side of the first table top 110.

[0107] See also Figure 3 and Figure 12 In this embodiment, since the first table top 110 can also slide along the first direction on the support member 120, the table top assembly can be closer to the center of the passenger seat, thereby improving the flexibility and convenience of the table top assembly. Figure 3 The table top assembly is shown at the left extreme position of the sliding stroke, corresponding to the retracted position; Figure 12 The table top assembly shown is located at the right extreme position of the sliding stroke, corresponding to the use position.

[0108] Specifically, when the passenger on the passenger seat wants to use the table assembly, assuming that the table assembly is stored and hidden in the armrest box 200, as shown in FIG. Figure 16 Under this premise, first flip open the armrest cover 220 to expose the accommodating cavity 201 and the table assembly therein, at which point the table 110, the support member 120 and the display member 300 are in the same position. Figure 1 and Figure 17 Then the exhibition piece 300 is rotated to an upright state, at which point the table 110, the support member 120 and the exhibition piece 300 are in the posture as shown Figure 2 and Figure 18 Then rotate the support member 120 to a flat state, at which point the table 110 and the support member 120 are in the same position as shown. Figure 3 As shown, the table top 110 is in the retracted position and stacked; then the table top 110 is moved to the right to the use position, at which time the posture of the table top 110 and the support member 120 is as shown Figure 12 Finally, the upper side of the table 110 is flipped to the right so that the table assembly is in an unfolded state. At this time, the table 110, the support member 120 and the display member 300 are in the same posture as shown. Figure 13 and Figure 14 As shown. In this way, the entire unfolding operation of the table board assembly is completed. It can be understood that the retraction operation of the table board assembly is the opposite of the aforementioned unfolding operation, so it will not be repeated here.
