In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Fig. 1-12 schematically illustrate the vehicle table of the present invention.

Referring to fig. 1-12, in some embodiments, a vehicle table 10 includes a table top 1 and two linkage assemblies 2.

The table board 1 is connected with the vehicle body of the vehicle through the two linkage assemblies 2, and the installation on the vehicle body is realized. Referring to fig. 2, in some embodiments, the table panel 1 includes an outer panel 11 and an inner panel 12, and the outer panel 11 is sleeved outside the inner panel 12. Specifically, the outer panel 11 and the inner panel 12 are each substantially U-shaped in cross section, and the outer panel 11 is housed outside the inner panel 12 and connected to each other. Thus, the table board 1 is constructed in an inner and outer double-layer board structure, has a cavity inside, and is light in weight. The outer panel 11 and the inner panel 12 may be connected to each other by tapping screws.

The two linkage assemblies 2 are respectively arranged on two opposite sides of the table plate 1 and used for realizing connection of the table plate 1 and two opposite side walls of the vehicle body. For example, in some embodiments, the vehicle is a commercial truck such as a heavy truck or a tractor, and the two linkage assemblies 2 connect the table 1 to two side walls of the sleeper compartment so that the vehicle table 10 can be hidden in the sleeper compartment when not needed. Referring to fig. 6, the two linkage assemblies 2 may be connected by a connecting member 3. The both ends of connecting piece 3 are connected with two linkage assembly 2 respectively for connecting piece 3 spans between two linkage assembly 2, and is connected between two linkage assembly 2 and forms the H type, and this motion synchronism that can improve two linkage assembly 2 on the one hand, and on the other hand also can reduce rocking and rotation between two linkage assembly 2, improves automobile-used table 10 overall structure's stability and reliability.

In addition to the connection between the table board 1 and the vehicle body, the two linkage assemblies 2 enable the table board 1 to move between a retracted position, an extended position and an opened position, so that the table board 1 can be pushed in and pulled out, folded and opened, and the requirements of different states of the vehicle table 10 during use and non-use are met.

Wherein the retracted position is an initial position of the table board 1, and is also an extreme position in which the vehicle table 10 is pushed in. When the desk is in the retracted position, the desk board 1 is not pulled out, but is hidden in a hidden space of a vehicle such as a sleeper box, so that when the desk 10 for the vehicle is not needed to be used, the desk 10 for the vehicle is stored, and the occupation of the desk 10 for the vehicle on a passenger space is reduced.

The extended position is an extreme position in which the table 1 is pulled out, and is also a transition position in which the table 1 moves from the retracted position to the open position. The table 1 is pulled out to the extreme position from the hidden space of the vehicle such as a sleeper box even if the table 1 is moved from the retracted position to the extended position.

The open position is a position where the table 1 is turned over from the extended position, and is also a position where the table 1 is used. The open position is generally horizontally between the extended position and the retracted position and vertically above the extended position and the retracted position. The table board 1 which is moved to the extending position is turned upwards, and then the table board 1 can be moved to the opening position from the extending position.

When needing to use, pull out table 1 to the extended position by the withdrawal position, then upwards overturn table 1, make table 1 move to the open position by the extended position, change the state of table 1 into the open state by fold condition, supply the passenger to carry out work, have a dinner, amusement or put the thing in occasions such as parking.

After finishing using, downwards overturn table 1, fold table 1, make table 1 move to the extended position by open position, later with table 1 push back to the withdrawal position again, make table 1 accomodate again in the hidden space of vehicles such as sleeping berth case, wait for next use.

Next, the structure of the linkage assembly 2 will be explained.

Referring to fig. 1-12, in some embodiments, linkage assembly 2 includes a rail 21 and a linkage 22.

The guide rail 21 is adapted to be connected to the vehicle body and to the table 1 via a linkage 22 so that the table 1 can be moved along the guide rail 21 between the extended position and the retracted position. Referring to fig. 1, in some embodiments, the guide rail 21 includes a rail 21a and a slider 21 b. The rail 21a is used for connection with a vehicle body. The slider 21b is slidably disposed in the rail 21a and connected to the table 1 through a link mechanism 22. Wherein, various connection modes can be adopted between the track 21a and the vehicle body. As one of them, referring to fig. 1, in some embodiments, the linkage assembly 2 includes a bracket 23, the bracket 23 is connected to the vehicle body by a connecting member such as a bolt, and the rail 21a is connected to the bracket 23 by welding or the like, so as to fix the rail 21a to the vehicle body. Along the length direction of the rail 21a, a plurality of brackets 23 may be arranged at intervals to realize more stable and reliable support for the rail 21 a.

Based on the provided rail 21a and slider 21b, the rail 21a and slider 21b serve as a fixed portion and a sliding portion of the guide rail 21, respectively, so that when the table 1 is pushed and pulled, the slider 21b can slide along the rail 21a, enabling movement of the table 1 along the rail 21a, so that the table 1 can move between the retracted position and the extended position.

Compare with the condition that guide rail 21 adopted the multisection rail body sliding connection structure, when guide rail 21 adopted track 21a and slider 21b sliding fit's structure, because slider 21b slides in track 21 a's stroke range, consequently, can effectively shorten guide rail 21's cantilever length, avoid causing table 1 to rock because of the cantilever overlength to can effectively promote table 1 stability.

The linkage mechanism 22 connects the guide rail 21 and the table 21, on one hand, the guide rail 21 can stretch out and draw back when the table 1 is pushed and pulled, so that the table 1 can move between the retraction position and the extension position, on the other hand, the table 1 can be turned over, so that the table 1 can move between the extension position and the opening position, and the table 1 can be switched between the folding state and the opening state.

Referring to fig. 1-12, in some embodiments, the linkage 22 includes a first linkage 22a and a second linkage 22 b. The guide rail 21 is connected to the table 1 sequentially via a first linkage 22a and a second linkage 22b, that is, the first linkage 22a connects the guide rail 21 and the second linkage 22b, and the second linkage 22b connects the first linkage 22a and the table 1. Specifically, the first link mechanism 22a is connected to a sliding portion (e.g., the slider 21b) of the guide rail 21. The second linkage 22b is rotatably connected between the first linkage 22a and the table 1 such that the table 1 can be flipped to move between the extended position and the open position.

Referring to fig. 1-12, in some embodiments, the second linkage 22b includes a first linkage member 223 and a second linkage member 224. The first and second links 223, 224 are each rotatably connected between the first linkage 22a and the table top 1 such that the table top 1 can move between the extended position and the open position. Wherein the first linkage member 223 and the second linkage member 224 are arranged side by side in the direction in which the two linkage assemblies 2 are oppositely arranged, for example, referring to fig. 11, in some embodiments, the second linkage member 224 is arranged on a side of the first linkage member 223 close to the other linkage assembly 2, or in other embodiments, the second linkage member 224 is arranged on a side of the first linkage member 223 far from the other linkage assembly 2.

Referring to fig. 6 and 9, when the table 1 moves between the extended position and the retracted position, the second linkage 22b does not rotate relative to the first linkage 22a and the table 1, the first linkage 223 and the second linkage 224 are both substantially parallel to the telescopic direction of the guide rail 21 (actually, the sliding direction of the sliding portion such as the slider 21b, and also the longitudinal direction of the guide rail 21 or the rail 21a), and at this time, the first linkage 223 and the second linkage 224 are also both parallel to the table top of the table 1, and the table 1 is not supported above the guide rail 21 by the second linkage 22b, but is stacked on the guide rail 21.

Referring to fig. 11, when the table 1 moves to the open position, the second link 22b rotates relative to the first link 22a and the table 1, so that the relative positional relationship between the first link 223 and the second link 224 and the first link 22a and the table 1 changes, wherein the first link 223 changes from being parallel to the extension and contraction direction of the guide rail 21 to being perpendicular to the extension and contraction direction of the guide rail 21, the second link 224 changes from being parallel to the extension and contraction direction of the guide rail 21 to being inclined relative to the extension and contraction direction of the guide rail 21, at this time, the table 1 is supported above the guide rail 21 by the second link 22b, the first link 223 is vertically connected between the table 1 and the first link 22a, and the second link 224 is obliquely connected between the table 1 and the first link 22 a. In this case, the first link 223 is perpendicular to the table 1, the second link 224 is inclined with respect to the first link 223, and the first and second links 223 and 224 form a triangle with the table 1 (as shown by a dotted line in fig. 11), so that the second link 22b forms a triangular support for the table 1. Because the triangle has stronger structural stability, compared with the L-shaped support in the related art, the triangle support can improve the stability of the table board 1 and reduce the shaking of the table board 1.

Therefore, based on the set linkage mechanism 22, the triangular support for the table board 1 can be realized after the table board 1 is opened, the problems that the table board 1 is unstable and the shaking amount is large in the related art are solved, and the use stability of the table board 1 is effectively improved.

In addition, the provided linkage mechanism 22 can improve the stability of the table board 1 without providing a leg, which is beneficial to realizing the simplification of the structure of the vehicle table 10 and the using steps of the vehicle table 10, and is beneficial to saving the occupation of the vehicle riding space when the vehicle table 10 is opened.

In some correlation techniques, to the relatively poor problem of table stability that the L shape supported the cause, set up folding landing leg on the table, through propping up the back with the table at linkage assembly, open the landing leg again, carry out the auxiliary stay to the table, improve table stability. This kind of mode of addding the landing leg, though can to a certain extent, improve table stability, but also lead to automobile-used table overall structure complicated, the operating procedure is loaded down with trivial details during the use, simultaneously, because the landing leg need occupy certain passenger space after opening, consequently, still lead to the requirement to passenger space to improve, restriction automobile-used table is in the application of passenger space narrow and small vehicle.

And set up to have through linking subassembly 2 and carry out the first linkage 223 and the second linkage 224 that triangle-shaped supported to table 1 for linking subassembly 2 self can form the stable support to the table, owing to need not to set up the landing leg, therefore, the structure is simpler, it is more convenient to operate, can save the landing leg simultaneously and take up to the passenger space, reduce the requirement of automobile-used table 10 to the passenger space, make automobile-used table 10 also can install and use in the narrow and small vehicle in passenger space, effectively enlarge the range of application of automobile-used table 10.

To achieve the rotational connection between the first and second linkage members 223, 224 and the table 1, referring to fig. 1 and 11, in some embodiments, the linkage assembly 2 includes a first mounting seat 227 and a second mounting seat 228. The first mounting seat 227 and the second mounting seat 228 are both mounted on the lower surface of the table top 1, for example, the first mounting seat 227 and the second mounting seat 228 are detachably connected to the table top 1 by a connecting member such as a screw, or the first mounting seat 227 and the second mounting seat 228 are non-detachably connected to the table top 1 by other means such as welding. The first mounting seat 227 and the second mounting seat 228 are respectively provided with a first connecting groove and a second connecting groove, the first linkage member 223 and the second linkage member 224 are respectively inserted into the first connecting groove and the second connecting groove and are penetrated by the pin 225, so that the rotatable connection between the first linkage member 223 and the first mounting seat 227 and between the second linkage member 224 and the second mounting seat 228 is realized, and the table board 1 can be turned relative to the second linkage mechanism 22 b. The first connecting groove and the second connecting groove can be U-shaped grooves or V-shaped grooves.

Whereas, to achieve the rotational connection relationship of the first and second linkage members 223 and 224 and the first linkage mechanism 22a, referring to fig. 1-12, in some embodiments, the first linkage mechanism 22a is provided with a first slot 222a and a second slot 222b, and the first and second slots 222a and 222b are arranged in sequence in a direction from the extended position to the retracted position, i.e., the first slot 222 is located upstream of the second slot 222b in the direction from the extended position to the retracted position. The first and second link members 223 and 224 are rotatably coupled in the first and second grooves 222a and 222b, respectively. For example, referring to fig. 3 and 10, in some embodiments, pin holes 222c are formed in the groove walls of the first and second grooves 222a and 222b, and a pin 225 passes through the pin holes 222c and the first and second links 223 and 224 inserted into the first and second grooves 222a and 222b to rotatably connect the first and second links 223 and 224 to the first linkage 22a, wherein the first and second links 223 and 224 are rotatably connected to the first linkage 22a through the pin 225.

Here, the first groove 222a is configured as a U-shaped groove in order to facilitate the insertion of the first link 223 into the first groove 222 a. To facilitate insertion of the second link member 224 into the second groove 222b, the second groove 222b is configured as a U-shaped groove. Specifically, referring to fig. 3, in some embodiments, the first and second grooves 222a and 222b include first and second groove segments 222g and 222h, the first and second groove segments 222g and 222h sequentially communicate in a direction from the extended position to the retracted position, the first groove segment 222g is an arc-shaped groove, the second groove segment 222h is a rectangular groove, and an end of the first groove segment 222g facing the extended position and upper ends of the first and second groove segments 222h and 222g are open. Like this, first groove 222a and second groove 222b are all roughly the U type, make things convenient for first linkage 223 and second linkage 224 to insert, simultaneously, form the rotary motion pair based on the U type groove, also are favorable to improving manufacturing and cooperation precision, restrict the volume of rocking of first linkage 223 and second linkage 224, promote the stability and the reliability of automobile-used table 10 overall structure. And. The provision of the first slot section 222g having an arcuate shape also facilitates rotation of the first and second linkage members 223, 224 relative to the first linkage 22 a.

Referring to fig. 5, in some embodiments, the first link member 223 is provided with an elongated hole 223a (e.g., an elongated hole), and the first link member 223 is rotatably connected to the first groove 222a through the elongated hole 223 a. Specifically, when the first link 223 and the first linkage 22a are connected by the pin 225, the pin 225 passes through the first link 223 via the elongated hole 223a, so that the pin 225 can pass through the pin hole 222c and the elongated hole 223a on the groove wall of the first groove 222a, and the rotatable connection of the first link 223 in the first groove 222a is realized.

Based on the elongated hole 223a, referring to fig. 10 and 12, on one hand, the first link 223 can rotate more conveniently between a position parallel to the guide rail 21 and a position perpendicular to the guide rail 21, and on the other hand, after the first link 223 rotates to a position perpendicular to the guide rail 21, the first link 223 can be in local rigid contact with the first link 22a, and is more stably and reliably limited.

In the above embodiments, the structures of the first and second link members 223 and 224 may be various.

For example, referring to fig. 5, in some embodiments, the first link 223 is a plate-shaped member, and the first end and the second end of the plate-shaped member are respectively provided with an elongated hole 223a and a circular hole for passing two pins 225, so as to achieve the rotatable connection between the first link 223 and the first groove 222a and the first mounting seat 227, and further achieve the rotatable connection between the first link 223 and the first linkage 22a and the table 1.

Referring to fig. 1 and 11, in some embodiments, the second link member 223 is a rod-shaped member, and the first end and the second end of the rod-shaped member are respectively provided with a circular hole for passing two pins 225, so as to realize the rotatable connection between the second link member 224 and the second groove 222b and the second mounting seat 228, and further realize the rotatable connection between the second link member 224 and the first linkage 22a and the table 1.

Additionally, in some embodiments, the second linkage 224 may telescope and shorten during movement of the table 1 from the extended position to the open position. In this way, the second linkage member 224 may better satisfy the different requirements for the distance between the second mounting seat 228 and the first linkage 22a in the unfolded state and the folded state. When the table top 1 is not moved to the open position and is in the folded position, the second linkage member 224 is in the extended state, which can satisfy the requirement of a longer distance between the second mounting seat 228 and the first linkage mechanism 22 a. When the table top 1 moves from the extended position to the open position and switches from the folded state to the open state, the distance between the second mounting seat 228 and the first linkage mechanism 22a is shortened, so that the second linkage member 224 is shortened, and the requirement of gradually shortening the distance between the second mounting seat 228 and the first linkage mechanism 22a can be met.

As one implementation of the second linkage member 224, referring to fig. 1 and 11, in some embodiments, the second linkage member 224 includes a drive cylinder and a filler disposed in a rod cavity of the drive cylinder to apply pressure to a piston of the drive cylinder. Wherein, the filler can be gas or spring. When the fill is a gas, the second linkage member 224 is a gas spring. When the filling is a spring, the second linkage member 224 may be considered as a modified structure of the gas spring by replacing the gas in the gas spring with a spring, in which case the second linkage member 224 may be referred to as a spring support rod. When the second link 224 is a spring support rod, it is possible to more smoothly perform the movement of the table 1 between the extended position and the open position and to more reliably support the table 1 after the table 1 is moved to the open position, as compared to the case where the second link 224 is a gas spring.

Next, the structure of the first link mechanism 22a will be further described.

Referring to fig. 7 in conjunction with fig. 3-4 and 9-12, in some embodiments, the first linkage 22a includes a support base 222 and a connecting frame 221, the support base 222 is connected to the guide rail 21 via the connecting frame 221, and the first linkage 223 and the second linkage 224 are rotatably connected to the support base 222.

Referring to fig. 3, the supporting base 222 includes a first base 222d and a second base 222 e. In the direction in which the two linkage assemblies 2 are arranged oppositely, the second seat 222e is connected to the surface of the first seat 222d facing the other linkage assembly 2, and in the extending and retracting direction of the guide rail 21, the second seat 222e is connected to the middle of the first seat 222d, the aforementioned first groove 222a and second groove 222b are respectively disposed on the first seat 222d and the second seat 222e and are respectively located at the end of the first seat 222d and the end of the second seat 222e close to the extended position, so that the first groove 222a and the second groove 222b are arranged in sequence in the direction from the extended position to the retracted position, and the first linkage member 223 and the second linkage member 224 are respectively inserted, thereby realizing the rotational connection between the first linkage member 223 and the second linkage member 224 and the first linkage mechanism 22 a. Meanwhile, with continuing reference to fig. 3 in conjunction with fig. 7, in some embodiments, a third groove 222f is formed on the support base 222, and the aforementioned connecting member 3 is disposed in the third groove 222 f. Specifically, the third groove 222f extends from the first base 222d to the second base 222e and is recessed downward from the upper surfaces of the first base 222d and the second base 222e, and the connecting member 3 is embedded in the third groove 222f and connected to the bottom of the third groove 222f through a screw connector such as a screw. In this way, the connecting member 3 is connected to the supporting seat 222 to realize connection with the first linkage mechanism 22a and further to realize connection with the linkage assembly 2, so as to connect the two linkage assemblies 2 together, and thus the two linkage assemblies 2 and the connecting member 3 are connected to form an H shape. Meanwhile, by providing the third groove 222f, the upper surface of the connector 3 may be prevented from protruding from the upper surface of the support base 222.

Referring to fig. 4 and 10-12, in some embodiments, the connection frame 221 includes a first frame body 221a and a second frame body 221 b. The first frame 221a and the second frame 221b are connected to form an L-shape. The first frame 221a is located between the support base 222 and the guide rail 21, and is connected to the guide rail 21 (specifically, a sliding portion such as a slider 21b), for example, the first frame 221a is welded to the guide rail 21. The second frame 221b is located below the supporting base 222 and connected to the supporting base 222, for example, the second frame 221b is connected to the supporting base 222 by a bolt 226. Like this, on the one hand, the link 221 can realize being connected between supporting seat 222 and guide rail 21 for when table 1 is pushed and pulled, link gear 22 can drive the sliding part and slide, realizes the removal of table 1 between the extended position and the retracted position, and on the other hand, link 221 still forms the support to supporting seat 222, can reduce rocking and the deformation of supporting seat 222, improves automobile table 10 overall structure's stability and reliability.

In the above embodiments, the material of the support base 222, the first mounting base 227 and the second mounting base 228 may be a zinc alloy processed by a die-casting process to improve the rigidity of the support base and enhance the scratch resistance of the surface.

Referring additionally to fig. 1 and 7-9, in some embodiments, the linkage assembly 2 includes a limit spring 24, a first resilient pad 25, and a second resilient pad 26. The elastic limit piece 24 serves as a first limit portion, and is connected to the first linkage 22a, so that when the guide rail 21 is extended and retracted, and the table board 1 moves between the retracted position and the extended position, the elastic limit piece 24 can move between the first end and the second end of the fixing portion (i.e., the rail 21 a). The first elastic pad 25 is used as a second limiting portion, which is disposed at the first end of the guide rail 21 (specifically, the first end of the fixing portion), and cooperates with the limiting elastic sheet 24 when the table board 1 moves to the retracted position, so as to limit the displacement of the table board 1 along the guide rail 21. The second elastic pad 26 is used as a third limiting portion, which is disposed at the second end of the guide rail 21 (specifically, the second end of the fixing portion), and cooperates with the limiting elastic sheet 24 when the table board 1 moves to the extended position, so as to limit the displacement of the table board 1 along the guide rail 21.

Based on the spacing shell fragment 24, first cushion 25 and second cushion 26 that set up, after table 1 moved to withdrawal position and extension position respectively, spacing shell fragment 24 can abut respectively on first cushion 25 and second cushion 26, through the interference fit with first cushion 25 and second cushion 26, carry out spacingly to the sliding part (for example slider 21b), and then restrict table 1 along the displacement of guide rail 21, prevent unexpected roll-off under the special operating mode conditions such as emergency brake or driver's cabin lift upset of table 1 for table 1 can stably and reliably keep in withdrawal position and extension position. Moreover, since the first linkage mechanism 21a does not move in the process of moving the table 1 from the extended position to the retracted position, the limit elastic piece 24 can still maintain the interference fit with the second elastic pad 26 in the process, so that the table 1 can still be prevented from accidentally sliding out.

It can be seen that, under the cooperation of the limiting elastic sheet 24, the first elastic pad 25 and the second elastic pad 26, the table board 1 can be reliably limited when the table board 1 is in the retracted position, the extended position and the opened position, so that the table board 1 can be stably maintained in the folded state and the opened state without accidentally slipping out.

Specifically, with continued reference to fig. 1 and 7-9, in some embodiments, the first elastic pad 25 and the second elastic pad 26 are both rubber pads, and are disposed at the rear end of the rail 21a (i.e., the first end of the rail 21, which is also the end of the rail 21a along the length from the extended position to the retracted position) and the front end of the rail 21a (i.e., the second end of the rail 21, which is also the end of the rail 21a along the length from the retracted position to the extended position), respectively. The position-limiting elastic piece 24 is disposed between the first frame 221a and the support base 222, and includes a first elastic piece 241 and a second elastic piece 242. The first elastic piece 241 and the second elastic piece 242 are respectively located at the front end and the rear end of the sliding portion (i.e., at the two ends along the extension direction of the guide rail 21), and each of the first elastic piece and the second elastic piece has a transverse portion 243, a transition portion 244 and a hook portion 245 which are connected in sequence. The lateral portion 243 is connected to the first link mechanism 22 a. The transition portion 244 extends from the lateral portion 243 to the rail 21a side and connects the lateral portion 243 and the hook portion 245. The hook 245 is bent from the transition 244 toward the lateral 243, and is located on one side of the sliding part in the longitudinal direction (i.e., the extending and retracting direction of the rail 21) to contact the first elastic pad 25 and the second elastic pad 26, thereby achieving a position-limiting function.

Since the hook portions 245 of the first elastic sheet 241 and the second elastic sheet 242 can contact the elastic pad (i.e., the first elastic pad 25 or the second elastic pad 26) from two sides of the elastic pad, respectively, when the slider 21b slides to the front end and the rear end of the track 21a, the displacement of the slider 21b along two directions of extension and contraction can be limited, thereby being beneficial to more accurately keeping the slider 21b at a desired position and further improving the stability of the overall structure.

In summary, in the vehicle table 10 shown in fig. 1 to 12, the first link member 223 and the second link member 224 are rotatably connected between the supporting seat 222 and the table board 1, and the table board 1 is turned and supported by the supporting seat 222. In addition, in the opened state, the first linkage member 223 and the second linkage member 224 form a triangular support structure, so that the support strength can be improved, the support legs are omitted, the use is more comfortable and stable, and the ergonomic shape is better met. Meanwhile, the guide rail 21 with the slide block 21b sliding in the stroke range of the rail 21a is adopted, so that the extension amount of the cantilever can be shortened, and the stability of the table board is improved. In addition, set up spacing shell fragment 24 and cushion, increase the limit function under folding and the open mode, can solve table 1 (for example vehicle emergency brake or driver's cabin lift upset) problem of easy roll-off under specific operating mode.

The operation of the vehicle table 10 shown in fig. 1-12 can be as follows:

referring to fig. 6-8, during driving, the table board 1 is folded and retracted to be hidden in the sleeper box. At this time, as shown in fig. 8, the position-limiting elastic sheet 24 is caught on the first elastic pad 25.

When the table plate 1 needs to be used during parking, firstly, the turnover cover plate at the front end of the sleeping box is opened, a hand is stretched into the sleeping box, the handle on the table plate 1 is held, the table plate 1 is pulled out, the table plate 1 is moved from the retracted position to the extended position, and at the moment, the limiting elastic sheet 24 is clamped on the second elastic pad 26 (see fig. 9-10); thereafter, referring to fig. 9-12, the table top 1 is turned upwards to rotate the first link 223 from horizontal to vertical, and at the same time, the second link 224 rotates from horizontal to inclined to form a triangular support structure to support the table top 1 above the guide rail 21, so as to open the table top 1, at this time, as shown in fig. 12, the top wall of the elongated hole 223a on the first link 223 presses on the pin 225 to form a limiting point of the first link 223.

When the table board 1 is used, the table board 1 is lifted upwards to separate the first linkage member 223 from the limiting point, then the table board 1 is turned downwards to enable the first linkage member 223 to rotate back to the horizontal position from the vertical position, the second linkage member 224 rotates back to the horizontal position from the inclined position, then the table board 1 is pushed into the sleeper box until the table board 1 returns to the retraction position, and at the moment, the limiting elastic sheet 24 is clamped on the first elastic pad 25 again.

Therefore, the whole process only needs to push, pull and turn the table plate 1, and the operation is simple and the use is convenient.

It will be appreciated that the vehicle table 10 of the present invention is not limited to the embodiment shown in figures 1-12.

For example, the connection between the outer panel 11 and the inner panel 12, between the first mounting seat 227 and the second mounting seat 228 and the table 1, and between the connecting bracket 221 and the supporting seat 222 are not limited to the connection shown in fig. 1 to 12, but other connection methods such as screw-Boss (Boss) connection, screw-socket connection, bolt-nut connection, snap-fit connection with engaging hole, or fusion welding post-fusion welding hole may be used.

For another example, the limiting structure that limits the displacement of the table board 1 along the guide rail 21 may not be limited to the first limiting portion including the limiting elastic sheet 24, the second limiting portion including the first elastic pad 25, and the third limiting portion including the second elastic pad 26, for example, as a modification, the first limiting portion, the second limiting portion, and the third limiting portion may also be a combination of a limiting pin and a limiting hole, or a combination of a limiting rib and a limiting groove, or a combination of a contour edge and a limiting flange, and for another example, the limiting structure may not include the second limiting portion and the third limiting portion at the same time, but only include one of the third limiting portion and the third limiting portion.

The above description is only exemplary of the present invention and should not be taken as limiting the invention, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
