[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of the present invention.

[0044] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0045] In the description of the present invention, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Figure 1-Figure 12 The vehicle table of the present invention is exemplarily shown.

[0048] Reference Figure 1-12 In some embodiments, the vehicle table 10 includes a table top 1 and two linkage components 2 .

[0049] The table top 1 is connected to the vehicle body through two linkage components 2 to achieve installation on the vehicle body. Figure 2 In some embodiments, the table top 1 includes an outer plate 11 and an inner plate 12, and the outer plate 11 is sleeved outside the inner plate 12. Specifically, the cross-sections of the outer plate 11 and the inner plate 12 are both roughly U-shaped, and the outer plate 11 is covered outside the inner plate 12 and connected to each other. In this way, the table top 1 is constructed as an inner and outer double-layer plate structure with a cavity inside and a light weight. The outer plate 11 and the inner plate 12 can be connected by self-tapping screws.

[0050] The two linkage components 2 are arranged on opposite sides of the table board 1, respectively, for realizing the connection between the table board 1 and the 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 components 2 connect the table board 1 to the two side walls of the berth box, so that the vehicle table 10 can be hidden in the berth box when not needed. Figure 6 , the two linkage components 2 can be connected by a connecting member 3. The two ends of the connecting member 3 are respectively connected to the two linkage components 2, so that the connecting member 3 spans between the two linkage components 2 and forms an H shape with the two linkage components 2. This can improve the movement synchronization of the two linkage components 2 on the one hand, and reduce the shaking and rotation between the two linkage components 2 on the other hand, thereby improving the stability and reliability of the overall structure of the vehicle table 10.

[0051] In addition to connecting the table top 1 to the vehicle body, the two linkage components 2 also enable the table top 1 to move between a retracted position, an extended position and an open position, so as to enable the table top 1 to be pushed in and out as well as folded and unfolded, thereby meeting the requirements for different states of the vehicle table 10 when in use and when not in use.

[0052] The retracted position is the initial position of the table board 1, and is also the limit position of the vehicle table 10. When in the retracted position, the table board 1 is not pulled out, but hidden in a hidden space of the vehicle such as a berth box, so that the vehicle table 10 can be stored when it is not needed, thereby reducing the occupation of the vehicle table 10 in the passenger space.

[0053] The extended position is the extreme position of the table board 1 being pulled out, and is also the transition position of the table board 1 moving from the retracted position to the open position. The table board 1 is pulled outward from the hidden space of the vehicle such as the berth box to the extreme position, that is, the table board 1 moves from the retracted position to the extended position.

[0054] The open position is the position of the table board 1 after it is flipped from the extended position, and is also the position of the table board 1 when it is in use. The open position is generally located between the extended position and the retracted position in the horizontal direction, and is located above the extended position and the retracted position in the vertical direction. By flipping the table board 1 that has moved to the extended position upward, the table board 1 can be moved from the extended position to the open position.

[0055] When it is needed, the table top 1 is pulled out from the retracted position to the extended position, and then flipped upward to move the table top 1 from the extended position to the open position, changing the state of the table top 1 from the folded state to the open state, so that passengers can work, dine, entertain or place things in parking and other occasions.

[0056] After use, flip the table board 1 downward and fold it so that the table board 1 moves from the open position to the extended position, and then push the table board 1 back to the retracted position so that the table board 1 is stored again in a hidden space of the vehicle such as a berth box, waiting for the next use.

[0057] Next, the structure of the linkage component 2 will be described.

[0058] Reference Figure 1-12 In some embodiments, the linkage assembly 2 includes a guide rail 21 and a linkage mechanism 22 .

[0059] The guide rail 21 is used to connect with the vehicle body and is connected with the table top 1 through the linkage mechanism 22, so that the table top 1 can move along the guide rail 21 between the extended position and the retracted position. Figure 1 In some embodiments, the guide rail 21 includes a track 21a and a slider 21b. The track 21a is used to connect with the vehicle body. The slider 21b is slidably arranged in the track 21a and connected with the table top 1 through the linkage mechanism 22. Among them, the track 21a and the vehicle body can be connected in a variety of ways. As one of them, refer to Figure 1 In some embodiments, the linkage assembly 2 includes a bracket 23, the bracket 23 is connected to the vehicle body by bolts or other connectors, and the track 21a is connected to the bracket 23 by welding or other methods to achieve the installation and fixation of the track 21a on the vehicle body. Along the length direction of the track 21a, multiple brackets 23 can be arranged at intervals to achieve more stable and reliable support for the track 21a.

[0060] Based on the set track 21a and slider 21b, the track 21a and slider 21b are respectively used as the fixed part and the sliding part of the guide rail 21, so that when the table top 1 is pushed and pulled, the slider 21b can slide along the track 21a to realize the movement of the table top 1 along the track 21a, so that the table top 1 can move between the retracted position and the extended position.

[0061] Compared with the case where the guide rail 21 adopts a multi-section rail sliding connection structure, when the guide rail 21 adopts a structure in which the rail 21a and the slider 21b slide together, since the slider 21b slides within the travel range of the rail 21a, the cantilever length of the guide rail 21 can be effectively shortened, thereby avoiding the shaking of the table top 1 due to the excessive cantilever, thereby effectively improving the stability of the table top 1.

[0062] The linkage mechanism 22 connects the guide rail 21 and the table top 21. On the one hand, it allows the guide rail 21 to extend and retract when the table top 1 is pushed and pulled, thereby realizing the movement of the table top 1 between the retracted position and the extended position. On the other hand, it also allows the table top 1 to be flipped over, thereby realizing the movement of the table top 1 between the extended position and the open position, so that the table top 1 can switch between the folded state and the open state.

[0063] Reference Figure 1-12 In some embodiments, the linkage mechanism 22 includes a first linkage mechanism 22a and a second linkage mechanism 22b. The guide rail 21 is connected to the table top 1 through the first linkage mechanism 22a and the second linkage mechanism 22b in sequence, that is, the first linkage mechanism 22a connects the guide rail 21 and the second linkage mechanism 22b, and the second linkage mechanism 22b connects the first linkage mechanism 22a and the table top 1. Specifically, the first linkage mechanism 22a is connected to the sliding portion (e.g., the slider 21b) of the guide rail 21. The second linkage mechanism 22b is rotatably connected between the first linkage mechanism 22a and the table top 1, so that the table top 1 can be flipped over and move between the extended position and the open position.

[0064] Among them, refer to Figure 1-12 In some embodiments, the second linkage mechanism 22b includes a first linkage member 223 and a second linkage member 224. The first linkage member 223 and the second linkage member 224 are both rotatably connected between the first linkage mechanism 22a and the table top 1, so that the table top 1 can move between the extended position and the open position. In the direction in which the two linkage components 2 are arranged relative to each other, the first linkage member 223 and the second linkage member 224 are arranged side by side. 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 another linkage component 2, or, in other embodiments, the second linkage member 224 is arranged on a side of the first linkage member 223 away from another linkage component 2.

[0065] Reference Figure 6 and Fig. 9When the table top 1 moves between the extended position and the retracted position, the second linkage mechanism 22b does not rotate relative to the first linkage mechanism 22a and the table top 1, and the first linkage member 223 and the second linkage member 224 are both roughly parallel to the extension and retraction direction of the guide rail 21 (actually the sliding direction of the sliding parts such as the slider 21b, and also the length direction of the guide rail 21 or the track 21a). At this time, the first linkage member 223 and the second linkage member 224 are also parallel to the table top of the table top 1, and the table top 1 is not supported above the guide rail 21 by the second linkage mechanism 22b, but is stacked on the guide rail 21.

[0066] And refer to Fig.11 When the table top 1 moves to the open position, the second linkage mechanism 22b rotates relative to the first linkage mechanism 22a and the table top 1, so that the relative position relationship between the first linkage member 223 and the second linkage member 224 and the first linkage mechanism 22a and the table top 1 changes, wherein the first linkage member 223 changes from being parallel to the extension and retraction direction of the guide rail 21 to being perpendicular to the extension and retraction direction of the guide rail 21, and the second linkage member 224 changes from being parallel to the extension and retraction direction of the guide rail 21 to being inclined relative to the extension and retraction direction of the guide rail 21. At this time, the table top 1 is supported above the guide rail 21 by the second linkage mechanism 22b, the first linkage member 223 is vertically connected between the table top 1 and the first linkage mechanism 22a, and the second linkage member 224 is obliquely connected between the table top 1 and the first linkage mechanism 22a. In this case, the first linkage member 223 is perpendicular to the table top 1, the second linkage member 224 is inclined relative to the first linkage member 223, and a triangle is formed between the first linkage member 223 and the second linkage member 224 and the table top 1 (such as Fig.11 The second linkage mechanism 22b forms a triangular support for the table top 1. Since the triangle has a strong structural stability, the triangular support can improve the stability of the table top 1 and reduce the shaking of the table top 1 compared with the L-shaped support in the related art.

[0067] It can be seen that based on the provided linkage mechanism 22, the table top 1 can be supported in a triangular shape after being opened, thereby solving the problem of the table top 1 being unstable and having a large shaking amount in the related technology, and effectively improving the stability of the table top 1 during use.

[0068] Furthermore, the linkage mechanism 22 is provided so that the stability of the table top 1 can be improved without providing legs, which is beneficial to simplifying the structure of the vehicle table 10 and the steps of using the vehicle table 10, and is beneficial to saving the occupied vehicle passenger space when the vehicle table 10 is opened.

[0069] In some related technologies, in order to solve the problem of poor stability of the table top caused by the L-shaped support, foldable legs are set on the table top. After the linkage assembly props up the table top, the legs are opened to provide auxiliary support for the table top, thereby improving the stability of the table top. Although this method of adding legs can improve the stability of the table top to a certain extent, it also makes the overall structure of the car table complicated and the operation steps are cumbersome when used. At the same time, since the legs need to occupy a certain passenger space after being opened, it also leads to higher requirements for passenger space, limiting the application of car tables in vehicles with small passenger space.

[0070] By configuring the linkage assembly 2 to have a first linkage part 223 and a second linkage part 224 that can provide a triangular support for the table top 1, the linkage assembly 2 itself can form a stable support for the table top. Since there is no need to set up supporting legs, the structure is simpler and the operation is more convenient. At the same time, it can save the space occupied by the supporting legs and reduce the requirements of the vehicle table 10 for the passenger space, so that the vehicle table 10 can also be installed and used in vehicles with a small passenger space, effectively expanding the application range of the vehicle table 10.

[0071] In order to realize the rotation connection between the first linkage member 223 and the second linkage member 224 and the table top 1, refer to Figure 1 and Fig.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 board 1. For example, the first mounting seat 227 and the second mounting seat 228 are detachably connected to the table board 1 through connecting members such as screws, or the first mounting seat 227 and the second mounting seat 228 are non-detachably connected to the table board 1 by welding or other methods. In addition, the first mounting seat 227 and the second mounting seat 228 are respectively provided with a first connecting groove and a second connecting groove, and 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 passed through by the pin 225, so as to realize 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, so that the table board 1 can be flipped relative to the second linkage mechanism 22b. Among them, the first connecting groove and the second connecting groove can be U-shaped grooves or V-shaped grooves.

[0072] In order to realize the rotation connection relationship between the first linkage member 223 and the second linkage member 224 and the first linkage mechanism 22a, refer to Figure 1-12In some embodiments, the first linkage mechanism 22a is provided with a first slot 222a and a second slot 222b, and the first slot 222a and the second slot 222b are arranged in sequence in the direction from the extended position to the retracted position, that is, 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 linkage member 223 and the second linkage member 224 are rotatably connected to the first slot 222a and the second slot 222b, respectively. For example, referring to Figure 3 and Fig.10 In some embodiments, a pin hole 222c is provided on the groove wall of the first groove 222a and the second groove 222b, and the pin shaft 225 passes through the pin hole 222c and the first linkage member 223 and the second linkage member 224 inserted into the first groove 222a and the second groove 222b, so as to realize the rotational connection between the first linkage member 223 and the second linkage member 224 and the first linkage mechanism 22a. At this time, the first linkage member 223 and the second linkage member 224 are both rotationally connected to the first linkage mechanism 22a through the pin shaft 225.

[0073] In order to facilitate the insertion of the first linking member 223 into the first groove 222a, the first groove 222a is configured as a U-shaped groove. In order to facilitate the insertion of the second linking member 224 into the second groove 222b, the second groove 222b is configured as a U-shaped groove. Figure 3 In some embodiments, the first groove 222a and the second groove 222b include a first groove section 222g and a second groove section 222h, the first groove section 222g and the second groove section 222h are sequentially connected along the direction from the extended position to the retracted position, and the first groove section 222g is an arc groove, the second groove section 222h is a rectangular groove, and the end of the first groove section 222g facing the extended position and the upper ends of the first groove section 222h and the second groove section 222g are open. In this way, the first groove 222a and the second groove 222b are both roughly U-shaped, which is convenient for the first linkage 223 and the second linkage 224 to be inserted. At the same time, the rotational motion pair formed based on the U-shaped groove is also conducive to improving the manufacturing and matching accuracy, limiting the shaking amount of the first linkage 223 and the second linkage 224, and improving the stability and reliability of the overall structure of the vehicle table 10. And. The first groove section 222g with an arc shape is provided, which is also more convenient for the first linkage 223 and the second linkage 224 to rotate relative to the first linkage mechanism 22a.

[0074] Reference Figure 5In some embodiments, an elongated hole 223a (e.g., an oblong hole) is provided on the first linkage member 223, and the first linkage member 223 is rotatably connected to the first slot 222a through the elongated hole 223a. Specifically, when the first linkage member 223 and the first linkage mechanism 22a are connected by the pin 225, the pin 225 passes through the first linkage member 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 slot wall of the first slot 222a, thereby realizing the rotatable connection of the first linkage member 223 in the first slot 222a.

[0075] Based on the provided elongated hole 223a, refer to Fig.10 and Fig.12 On the one hand, the first linkage member 223 can more conveniently rotate between a position parallel to the guide rail 21 and a position perpendicular to the guide rail 21. On the other hand, after the first linkage member 223 rotates to a position perpendicular to the guide rail 21, the first linkage member 223 can be in partial rigid contact with the first linkage mechanism 22a and be limited more stably and reliably.

[0076] In the above-mentioned embodiments, the structures of the first linkage member 223 and the second linkage member 224 may be various.

[0077] For example, refer to Figure 5 In some embodiments, the first linkage member 223 is a plate-shaped member, and a long hole 223a and a round hole are respectively provided at the first end and the second end thereof, through which two pin shafts 225 pass, respectively, to achieve a rotatable connection between the first linkage member 223 and the first groove 222a and the first mounting seat 227, and further achieve a rotatable connection between the first linkage member 223 and the first linkage mechanism 22a and the table top 1.

[0078] Reference Figure 1 and Fig.11 In some embodiments, the second linkage member 223 is a rod-shaped member, and a circular hole is provided at the first end and the second end thereof, respectively, for two pin shafts 225 to pass through, so as to realize a rotatable connection between the second linkage member 224 and the second groove 222b and the second mounting seat 228, and further realize a rotatable connection between the second linkage member 224 and the first linkage mechanism 22a and the table top 1.

[0079] In addition, in some embodiments, the second linkage member 224 is retractable and shortens during the process of the table top 1 moving from the extended position to the open position. In this way, the second linkage member 224 can better meet the different requirements of the open state and the folded state for the distance between the second mounting seat 228 and the first linkage mechanism 22a. When the table top 1 does not move to the open position and is in the folded state, the second linkage member 224 is in a stretched state, which can meet the requirement of a longer distance between the second mounting seat 228 and the first linkage mechanism 22a. 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 becomes shorter. Therefore, the second linkage member 224 is shortened, which can meet the requirement of a gradually shortening distance between the second mounting seat 228 and the first linkage mechanism 22a.

[0080] As an implementation method of the second linkage member 224, refer to Figure 1 and Fig.11 In some embodiments, the second linkage 224 includes a drive cylinder and a filler, wherein the filler is disposed in a rod cavity of the drive cylinder to apply pressure to the piston of the drive cylinder. The filler may be a gas or a spring. When the filler is a gas, the second linkage 224 is a gas spring. When the filler is a spring, the second linkage 224 can be regarded as a deformed structure of the gas spring, which is obtained by replacing the gas in the gas spring with a spring. In this case, the second linkage 224 can be referred to as a spring support rod. Compared with the case where the second linkage 224 is a gas spring, when the second linkage 224 is a spring support rod, the movement of the table top 1 between the extended position and the open position can be achieved more smoothly, and the table top 1 can be more reliably supported after the table top 1 moves to the open position.

[0081] Next, the structure of the first linkage mechanism 22a will be further described.

[0082] Reference Figure 7 , and combined with Figure 3-4 and Figure 9-12 In some embodiments, the first linkage mechanism 22a includes a support seat 222 and a connecting frame 221, the support seat 222 is connected to the guide rail 21 through the connecting frame 221, and the first linkage member 223 and the second linkage member 224 are rotatably connected to the support seat 222.

[0083] Among them, refer to Figure 3The support seat 222 includes a first seat body 222d and a second seat body 222e. In the direction in which the two linkage components 2 are arranged relative to each other, the second seat body 222e is connected to the surface of the first seat body 222d facing the other linkage component 2, and in the extension direction of the guide rail 21, the second seat body 222e is connected to the middle of the first seat body 222d. The first groove 222a and the second groove 222b mentioned above are respectively arranged on the first seat body 222d and the second seat body 222e, and are respectively located at one end of the first seat body 222d and the second seat body 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 are respectively inserted into the first linkage member 223 and the second linkage member 224, so as to realize the rotational connection between the first linkage member 223 and the second linkage member 224 and the first linkage mechanism 22a. At the same time, continue to refer to Figure 3 , and combined with Figure 7 In some embodiments, the support seat 222 is provided with a third groove 222f, and the aforementioned connecting member 3 is arranged in the third groove 222f. Specifically, the third groove 222f extends from the first seat body 222d to the second seat body 222e, and is recessed downward from the upper surfaces of the first seat body 222d and the second seat body 222e. The connecting member 3 is embedded in the third groove 222f and is connected to the bottom of the third groove 222f through a threaded connecting member such as a screw. In this way, the connecting member 3 is connected to the support seat 222 to achieve connection with the first linkage mechanism 22a, and then to achieve connection with the linkage assembly 2, and the two linkage assemblies 2 are connected together, so that the connection between the two linkage assemblies 2 and the connecting member 3 forms an H-shape. At the same time, by providing the third groove 222f, it is possible to prevent the upper surface of the connecting member 3 from protruding from the upper surface of the support seat 222.

[0084] Reference Figure 4 and Figure 10-12 In some embodiments, the connecting frame 221 includes a first frame 221a and a second frame 221b. The first frame 221a and the second frame 221b are connected in an L shape. The first frame 221a is located between the support seat 222 and the guide rail 21, and is connected to the guide rail 21 (specifically, the sliding part such as the slider 21b). For example, the first frame 221a is welded to the guide rail 21. The second frame 221b is located below the support seat 222 and is connected to the support seat 222. For example, the second frame 221b and the support seat 222 are connected by bolts 226. In this way, on the one hand, the connecting frame 221 can realize the connection between the support seat 222 and the guide rail 21, so that when the table board 1 is pushed and pulled, the linkage mechanism 22 can drive the sliding part to slide, so as to realize the movement of the table board 1 between the extended position and the retracted position. On the other hand, the connecting frame 221 also supports the support seat 222, which can reduce the shaking and deformation of the support seat 222 and improve the stability and reliability of the overall structure of the vehicle table 10.

[0085] In the above-mentioned embodiments, the material of the support seat 222, the first mounting seat 227 and the second mounting seat 228 may be a zinc alloy processed by a die-casting process to improve its own rigidity and enhance the surface scratch resistance.

[0086] In addition, refer to Figure 1 as well as Figure 7-9 In some embodiments, the linkage assembly 2 includes a limiting spring piece 24, a first elastic pad 25, and a second elastic pad 26. The limiting spring piece 24 is used as a first limiting portion, which is connected to the first linkage mechanism 22a, so that when the guide rail 21 is extended and the table top 1 moves between the retracted position and the extended position, the limiting spring piece 24 can move between the first end and the second end of the fixed portion (i.e., the track 21a). The first elastic pad 25 is used as a second limiting portion, which is arranged at the first end of the guide rail 21 (specifically, the first end of the fixed portion), and when the table top 1 moves to the retracted position, it cooperates with the limiting spring piece 24 to limit the displacement of the table top 1 along the guide rail 21. The second elastic pad 26 is used as a third limiting portion, which is arranged at the second end of the guide rail 21 (specifically, the second end of the fixed portion), and when the table top 1 moves to the extended position, it cooperates with the limiting spring piece 24 to limit the displacement of the table top 1 along the guide rail 21.

[0087] Based on the provided limiting spring piece 24, the first elastic pad 25 and the second elastic pad 26, when the table top 1 moves to the retracted position and the extended position respectively, the limiting spring piece 24 can abut against the first elastic pad 25 and the second elastic pad 26 respectively, and limit the sliding part (such as the slider 21b) by the interference fit with the first elastic pad 25 and the second elastic pad 26, thereby limiting the displacement of the table top 1 along the guide rail 21, preventing the table top 1 from accidentally sliding out under specific working conditions such as emergency braking or cab lifting and flipping, so that the table top 1 can be stably and reliably maintained in the retracted position and the extended position. In addition, since the first linkage mechanism 21a does not move during the movement of the table top 1 from the extended position to the retracted position, the limiting spring piece 24 can still maintain the interference fit with the second elastic pad 26 during this process, thereby still preventing the table top 1 from accidentally sliding out.

[0088] It can be seen that with the cooperation of the limiting spring piece 24, the first elastic pad 25 and the second elastic pad 26, the table top 1 can be reliably limited when the table top 1 is in the retracted position, the extended position and the open position, so that the table top 1 can be stably maintained in the folded state and the open state without accidentally sliding out.

[0089] Specifically, continue to refer to Figure 1 as well as Figure 7-9In some embodiments, the first elastic pad 25 and the second elastic pad 26 are both rubber pads, which are respectively arranged at the rear end of the track 21a (i.e., the first end of the aforementioned guide rail 21, which is also the end of the track 21a from the extended position to the retracted position) and the front end of the track 21a (i.e., the second end of the aforementioned guide rail 21, which is also the end of the track 21a from the retracted position to the extended position). The limiting spring 24 is arranged between the first frame 221a and the support seat 222, and includes a first spring 241 and a second spring 242. The first spring 241 and the second spring 242 are respectively located at the front and rear ends of the sliding part (i.e., the two ends along the extension direction of the guide rail 21), and both have a transverse portion 243, a transition portion 244 and a hook portion 245 connected in sequence. The transverse portion 243 is connected to the first linkage mechanism 22a. The transition portion 244 extends from the transverse portion 243 to one side of the track 21a, and connects the transverse portion 243 and the hook portion 245. The hook portion 245 is bent from the transition portion 244 to one side of the transverse portion 243 and is located on one side of the length direction of the sliding portion (which is also the extension direction of the guide rail 21 ) for contacting the first elastic pad 25 and the second elastic pad 26 to achieve a limiting function.

[0090] Since the hook portions 245 of the first elastic sheet 241 and the second elastic sheet 242 can contact the elastic pads (i.e., the first elastic pad 25 or the second elastic pad 26) from both sides thereof, when the slider 21b slides to the front and rear ends of the track 21a, the displacement of the slider 21b in both directions of extension and contraction can be limited, thereby facilitating the slider 21b to be more accurately maintained at the desired position, further improving the stability of the overall structure.

[0091] In summary, Figure 1-12 The vehicle table 10 shown in the figure has the first linkage member 223 and the second linkage member 224 rotatably connected between the support seat 222 and the table top 1, and the table top 1 is turned over and supported and limited by the transition of the support seat 222. Moreover, in the open state, the first linkage member 223 and the second linkage member 224 form a triangular support structure, which can improve the support strength and save the legs, making it more comfortable and stable when used, and more ergonomic. At the same time, the guide rail 21 in which the slider 21b slides within the travel range of the track 21a can shorten the cantilever extension and improve the stability of the table top. In addition, the limiting spring piece 24 and the elastic pad are provided to increase the limiting function in the folded and opened states, which can solve the problem that the table top 1 is easy to slide out under certain working conditions (such as sudden braking of the vehicle or lifting and flipping of the cab).

[0092] Figure 1-12 The working process of the vehicle table 10 shown can be as follows:

[0093] Reference Figure 6-8 During driving, the table 1 is in a folded state and in a retracted position, hidden in the berth box. Figure 8As shown, the limiting spring piece 24 is clamped on the first elastic pad 25 .

[0094] When the table board 1 is needed for parking, the flip cover at the front end of the berth box is first opened, and the hand is put into the berth box, and the handle on the table board 1 is held, and the table board 1 is pulled out, so that the table board 1 moves from the retracted position to the extended position. At this time, the limit spring piece 24 is stuck on the second elastic pad 26 (see Figure 9-10 ); after that, refer to Figure 9-12 , flip the table top 1 upward, so that the first linkage member 223 rotates from horizontal to vertical, and at the same time, the second linkage member 224 rotates from horizontal to inclined, forming a triangular support structure, supporting the table top 1 above the guide rail 21, and realizing the opening of the table top 1. At this time, Fig.12 As shown, the top wall of the elongated hole 223 a on the first linkage member 223 is pressed on the pin shaft 225 to form a limiting point of the first linkage member 223 .

[0095] When the table top 1 is used, first lift the table top 1 upwards to disengage the first linkage 223 from the limit position, then flip the table top 1 downwards to rotate the first linkage 223 from the vertical position back to the horizontal position, and the second linkage 224 from the inclined position back to the horizontal position, then push the table top 1 into the berth box until the table top 1 returns to the retracted position, at which time the limit spring 24 is re-stuck on the first elastic pad 25.

[0096] It can be seen that the whole process only requires pushing, pulling and flipping the table top 1, which is simple to operate and easy to use.

[0097] It is understood that the vehicle table 10 of the present invention is not limited to Figure 1-12 The embodiment shown.

[0098] For example, the connection between the outer plate 11 and the inner plate 12, between the first mounting seat 227 and the second mounting seat 228 and the table top 1, and between the connecting frame 221 and the supporting seat 222 is not limited to Figure 1-12 Instead of the method shown in the figure, other methods such as the combination of screws and boss columns, screws and thorn holes, bolts and nuts, buckles and snap holes, or welding columns and welding holes can also be used.

[0099] For another example, the limiting structure for limiting the displacement of the table top 1 along the guide rail 21 may not be limited to the structural form in which the first limiting part includes a limiting spring piece 24, the second limiting part includes a first elastic pad 25, and the third limiting part includes a second elastic pad 26. For example, as a variation, the first limiting part and the second limiting part and the third limiting part 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. For another example, the limiting structure may not include the second limiting part and the third limiting part at the same time, but only include one of the third limiting part and the third limiting part.

[0100] The above description is only an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
