Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a pull-out table. Background Technology

[0002] Existing pull-out tabletops consist of two nested tabletops that can be pulled out to provide a larger usable area, while maintaining a compact size when folded. Due to their superior convenience, pull-out tabletops can be installed in vehicles to meet the needs of passengers. However, in related technologies, pull-out tabletops include a first tabletop and a second tabletop. When the second tabletop is pulled out from the first tabletop, its surface is often not flush with the first tabletop, creating a step between the two surfaces. This results in poor overall surface flatness, negatively impacting the user experience. Utility Model Content

Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0056] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0057] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0058] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0059] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0060] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0061] The pull-out tabletop of the related technology includes a first tabletop and a second tabletop. After the second tabletop is pulled out from the first tabletop, the tabletop of the second tabletop is often lower than the tabletop of the first tabletop. Therefore, there is a step between the tabletops of the first and second tabletops, which affects the flatness of the entire tabletop.

[0062] To improve the problem of poor tabletop flatness in the aforementioned related technologies, this application provides a pull-out tabletop. By improving the shape of the slide groove, the second tabletop can be lifted upwards after being pulled out, thereby reducing or even eliminating the step between the tabletops of the first and second tabletops, thus improving the flatness of the entire tabletop.

[0063] Figure 1 This is a schematic diagram of the pull-out tabletop being retracted in one embodiment of this application; Figure 2 This is a schematic diagram showing the pull-out tabletop unfolded in one embodiment of this application. Figure 1 and Figure 2 As shown, the pull-out tabletop provided in this embodiment includes a first tabletop 1 and a second tabletop 2. The first tabletop 1 has a first tabletop 111, and the second tabletop 2 has a second tabletop 211. The second tabletop 2 is slidably engaged with the first tabletop 1 so that the second tabletop 2 can be unfolded and retracted relative to the first tabletop 1. In this embodiment, the first direction is parallel to the first tabletop 111, which is also the unfolding / retracting direction of the pull-out tabletop. By unfolding the second tabletop 2, the usable tabletop area is expanded from the original first tabletop 111 to the sum of the first tabletop 111 and the second tabletop 211, thus giving the pull-out tabletop a larger usable area. The second direction is perpendicular to the first direction and parallel to the first tabletop 111. The third direction is perpendicular to the first tabletop 111. In this embodiment, the first direction is the vehicle driving direction, the second direction is the vehicle width direction, and the third direction is the vehicle vertical direction.

[0064] In this embodiment, the first tabletop 1 forms an open receiving cavity, and at least a portion of the second tabletop 2 is received within the receiving cavity. When the second tabletop 2 is unfolded relative to the first tabletop 1, the second tabletop 211 can extend out of the opening of the receiving cavity along a first direction; when the second tabletop 2 is retracted, the second tabletop 211 can retract back into the receiving cavity along the first direction from the opening of the receiving cavity. It should be understood that the receiving cavity formed by the first tabletop 1 in this embodiment can be open on multiple sides simultaneously, such as the side facing downwards being open; and the opening of the receiving cavity in this application specifically refers to the opening at one end of the receiving cavity in the first direction, and the opening of the receiving cavity is used for the second tabletop 2 to extend or retract. In other optional embodiments, the second tabletop 2 may also have a receiving cavity and be fitted over the first tabletop 1, so that when the second tabletop 2 is unfolded, the first tabletop 111 of the first tabletop is exposed, thereby increasing the total tabletop area.

[0065] In this embodiment, the pull-out tabletop also includes a storage compartment 3, which is used to store the first tabletop 1 and the second tabletop 2. The storage compartment 3 has an entrance and exit that communicates with the internal cavity. The first tabletop 1 can slide relative to the storage compartment 3 in a first direction so that the first tabletop 111 extends or retracts from the entrance and exit of the storage compartment 3. When the tabletop is not in use, the first tabletop 1 and the second tabletop 2 can be stored in the storage compartment 3, which can protect the first tabletop 1 and the second tabletop 2. When the tabletop is needed, a part of the first tabletop 1 can be pulled out from the entrance and exit of the storage compartment 3, ensuring that the first tabletop 111 extends out of the entrance and exit. Then, the second tabletop 2 can be pulled out from the first tabletop 1, so that the second tabletop 211 of the second tabletop 2 can be joined with the first tabletop 111 of the first tabletop 1 to form a tabletop for the user.

[0066] Figure 3 This is an exploded view of a pull-out tabletop in one embodiment of this application. Figure 3 As shown, the receiving chamber 3 includes a lower shell 32 and an upper shell 31, which are joined together in a third direction to form the internal cavity of the receiving chamber 3. In this embodiment, a slide rail 321 extending along a first direction is provided inside the receiving chamber 3, and the first table 1 is slidably engaged with the slide rail 321. By providing the slide rail 321, the movement direction of the first table 1 relative to the receiving chamber 3 is restricted to the first direction, thereby improving the reliability of the movement of the first table 1 relative to the receiving chamber 3. Specifically, two slide rails 321 are provided on the inner side of the lower shell 32, and a slider 15 correspondingly engaged with the slide rail 321 is provided on the first table 1.

[0067] The first table 1 has an exit position and an entry position relative to the containment chamber 3. Figure 4 This is a schematic diagram of the first table 1 in the warehouse position in one embodiment of this application; Figure 5 This is a schematic diagram showing the first table 1 in the unloading position according to one embodiment of this application. Figures 3 to 5 As shown, the pull-out table also includes a locking mechanism 5 and a driving mechanism 4. When the first table 1 is in the out-of-cabin position, the first tabletop 111 of the first table 1 extends out of the receiving compartment 3; when the first table 1 is in the in-cabin position, the first table 1 is inside the receiving compartment 3. In this embodiment, the driving mechanism 4 is used to give the first table 1 a tendency to move towards the out-of-cabin position. The locking mechanism 5 has a locked state and an unlocked state. When the first table 1 is in the in-cabin position and the locking mechanism 5 is in the locked state, the locking mechanism 5 prevents the first table 1 from moving towards the out-of-cabin position. When the locking mechanism 5 is in the unlocked state, the first table 1 is allowed to move from the in-cabin position to the out-of-cabin position. Therefore, when the user does not use the pull-out table, the first table 1 can be placed in the in-cabin position, and the locking mechanism 5 can be used to lock the first table 1 so that it does not move out of the receiving compartment 3; when the pull-out table is needed, the locking mechanism 5 can be unlocked, and then the first table 1 can extend from the entrance / exit of the receiving compartment 3 under the drive of the driving mechanism 4, and the first tabletop 111 can be used. When it is necessary to further expand the second desktop 211, the second desktop board 2 can be manually pulled out so that the second desktop 211 can be combined with the first desktop 111 to form a larger desktop.

[0068] Figure 6 This is a schematic diagram of the locking mechanism 5 locking the first table panel 1 in one embodiment of this application; Figure 7 This is a schematic diagram showing the first tabletop 1 being pushed out by the drive mechanism 4 after the locking mechanism 5 is unlocked in one embodiment of this application. Figure 6 and Figure 7 As shown, optionally, the drive mechanism 4 can be a coil spring. The first table 1 includes a push plate 16, which is located at the end of the first table 1 away from the entrance / exit of the receiving chamber 3. The coil spring is connected to the push plate 16. The coil spring can always maintain the first table 1 with a tendency to move out of the receiving chamber 3. Therefore, when the locking mechanism 5 is unlocked, the drive mechanism 4 can immediately eject the first table 1. Optionally, a limiting structure can be provided in the receiving chamber 3 to block the first table 1 and prevent the first table 1 from continuing to move outward after reaching the exit position. For example, a limiting part 322 is provided inside the lower shell 32. The limiting part 322 abuts against the first table 1 when the first table 1 reaches the exit position to achieve limiting. When it is necessary to retract the first table 1 into the receiving chamber 3, the first table 1 can be manually pushed to overcome the spring force of the drive mechanism 4. When the first table 1 returns to the entry position, the locking mechanism 5 locks the first table 1 in the entry position.

[0069] It should be understood that in other optional embodiments, the drive mechanism 4 may also adopt other structures, such as compression springs or tension springs; or, the drive mechanism 4 may also adopt mechanisms such as motors, cylinders, or hydraulic cylinders. Optionally, in order to improve the smoothness of the opening of the first table 1, a damping element 17 may be provided on a section of the first table 1 in the second direction.

[0070] Figure 8 This is a schematic diagram of the locking mechanism 5 in a locked state in one embodiment of this application; Figure 9 This is a schematic diagram of the locking mechanism 5 in an unlocked state in one embodiment of this application; Figure 10 This is a schematic diagram illustrating the engagement of a locking member 51 with a lock hole 121 according to an embodiment of this application. Figures 8 to 10 As shown, in this embodiment, the locking mechanism 5 includes a locking member 51 and a first elastic member 52. The locking member 51 is slidably connected to the receiving chamber 3 in the second direction. A lock hole 121 is provided on the first table 1. The first elastic member 52 is used to drive the locking member 51 to insert into the lock hole 121 to prevent the first table 1 from moving towards the exit position. The locking mechanism 5 also includes a pressing member 53, which is movably disposed in the receiving chamber 3 and protrudes from the surface of the receiving chamber 3. The pressing member 53 is convexly connected to the locking member 51. When the pressing member 53 moves into the receiving chamber 3, it drives the locking member 51 to overcome the elastic force of the first elastic member 52 and exit from the lock hole 121. Figure 10 As shown, a lock hole 121 is disposed on the end face of at least one end of the first tabletop 1 in the second direction, and a locking member 51 extends along the second direction and beyond the end face of the first tabletop 1. The end of the locking member 51 is bent downward to form a latch 511, which is used to be inserted into the lock hole 121 along the second direction. In this embodiment, the two end faces of the first tabletop 1 spaced apart in the second direction are connected by a mating part 12 (see...). Figure 11 The locking hole 121 is formed on the outer surface of the mating part 12.

[0071] It is understandable that when the first table 1 is in the insertion position, the locking tongue 511 can be inserted into the lock hole 121 in the second direction, thereby locking the first table 1.

[0072] In this embodiment, the receiving compartment 3 has a button opening, which is located at the same end of the receiving compartment 3 in the first direction as the inlet / outlet. The pressing member 53 can move relative to the receiving compartment 3 in the first direction. Specifically, the button opening is located on the upper shell 31, and the locking member 51 is slidably engaged with the upper shell 31. The locking member 51 can slide relative to the receiving compartment 3 in the second direction. The locking member 51 is provided with a guide groove 512, and the pressing member 53 is provided with a guide post 531, which is slidably engaged with the guide groove 512. It should be understood that the positions of the guide groove 512 and the guide post 531 can be interchanged, that is, the pressing member 53 is provided with a guide groove, while the locking member 51 is provided with a guide post. The guide groove 512 is inclined relative to the first and second directions. When the pressing member 53 moves into the receiving compartment 3, the guide post 531 slides along the guide groove 512 to force the locking member 51 to overcome the elastic force of the first elastic member 52 and move in the second direction.

[0073] In this embodiment, the locking mechanism 5 includes two locking members 51. The first tabletop 1 has locking holes 121 on its two end faces at both ends in the second direction. The guide post 531 of the pressing member 53 simultaneously slides with the guide grooves 512 on the two locking members 51. The two locking members 51 have opposite directions of movement under the drive of the pressing member 53. The two ends of the first elastic member 52 are connected to the two locking members 51 and provide a force that brings the two locking members 51 closer together. Optionally, the first elastic member 52 is a tension spring. Under the tension of the first elastic member 52, the two locking members 51 can move closer together, such as... Figure 8 As shown; at this time, the locking tongue 511 on the locking member 51 can be inserted into the lock hole 121, as shown. Figure 10 As shown. When the pressing member 53 is pressed by the user and moves into the receiving compartment 3, the guide post 531 can push the two locking members 51 away from each other in a second direction, as shown. Figure 9 As shown, at this time, the locking tongues 511 on the two locking parts 51 can be disengaged from the lock hole 121 to unlock, and then the first table 1 can be moved out of the containment chamber 3.

[0074] Furthermore, the locking mechanism 5 also includes a second elastic element 54, which is used to give the pressing member 53 a tendency to move outward from the receiving compartment 3, so that the pressing member 53 can automatically reset under the elastic force of the second elastic element 54 after being pressed by the user. Figure 8 and Figure 9 As shown, optionally, the second elastic element 54 is a spring sheet; in another embodiment, the second elastic element 54 may also be a compression spring, tension spring or other structures.

[0075] Furthermore, the surface of the first tabletop 1 is also provided with a storage groove 122 extending along a first direction. The storage groove 122 is used to store the locking tongue 511 of the locking member 51 after the first tabletop 1 is removed from the loading position. In this embodiment, the storage groove 122 is provided at the mating part 12 (see... Figure 11 The outer surface of the first table 1 is spaced apart from the receiving compartment 3 in the first direction. After the first table 1 is ejected from the receiving compartment 3, the locking tongue 511 on the locking member 51 can enter the receiving groove 122. Optionally, a smooth slope can be provided at one end of the receiving groove 122 near the locking hole 121. This slope smoothly connects the bottom of the receiving groove 122 and the outer surface of the first table 1, so that the process of the locking tongue 511 entering or leaving the receiving groove 122 can be smoother.

[0076] Figure 11 This is an assembly diagram of the first tabletop 1 and the second tabletop 2 in one embodiment of this application; Figure 12 This is a schematic diagram of the second tabletop 2 in one embodiment of this application. Figure 11 and Figure 12As shown in this application, one of the first tabletop 1 and the second tabletop 2 is provided with a sliding groove, and the other is provided with a sliding part. The sliding groove includes a push-pull section extending along a first direction and a traction section connected to one end of the push-pull section. The traction section is bent relative to the push-pull section. The sliding part is configured to enter the traction section along the push-pull section during the unfolding of the second tabletop 2, and under the guidance of the traction section, bring the second tabletop 211 closer to the spatial plane where the first tabletop 111 is located. Specifically, the unfolding process of the second tabletop 2 is the process of the second tabletop 211 being pulled out of the receiving cavity. Since the second tabletop 2 can move towards the spatial plane where the first tabletop 111 is located during the pulling process under the guidance of the sliding groove, the step between the first tabletop 111 and the second tabletop 211 can be reduced or even eliminated, improving flatness. Furthermore, the traction section has an end position. When the sliding part is at the end position, the second tabletop 211 is flush with the first tabletop 111. When the second tabletop 211 is flush with the first tabletop 111, the step between the first tabletop 111 and the second tabletop 211 is eliminated, and the two are connected (unavoidable gaps are allowed). It can be understood that when the sliding part is at the end position, the second tabletop 211 is completely pulled out from the first tabletop 1, which is the usage state of the pull-out tabletop with the maximum tabletop area.

[0077] In this embodiment, the first tabletop 1 includes a first plate body 11 and a mating portion 12 connected to the first plate body 11, and a first tabletop 111 is formed on the first plate body 11. A sliding groove is provided on the mating portion 12, the traction section is bent relative to the push-pull section towards the first tabletop 111, and sliding portions are provided at both ends of the second tabletop 2 in the second direction. Specifically, the first tabletop 1 includes two mating portions, and the two mating portions 12 are respectively provided at both ends of the first plate body 11 in the second direction. Sliding portions are provided at both ends of the second tabletop 2 in the second direction. The first plate body 11 has a back surface opposite to the first tabletop 111, and the back surface of the first plate body 11 and the two mating portions 12 together form a receiving cavity for accommodating at least a portion of the second tabletop 2.

Figures 13 to 18 As shown, in this embodiment, each mating part 12 is provided with a first sliding groove 13 and a second sliding groove 14. The first sliding groove 13 includes a first push-pull section 131 and a first traction section 132, and the second sliding groove 14 includes a second push-pull section 141 and a second traction section 142. The first push-pull section 131 and the second push-pull section 141 are arranged at intervals in the first direction, and the second push-pull section 141 is closer to the front end of the second table 2 relative to the first push-pull section 131. It should be understood that the front end of the second table 2 refers to the end that can extend out of the receiving cavity in the first direction, and the rear end of the second table 2 is the end that is retained in the receiving cavity. The second table 2 is provided with a first sliding part 221 and a second sliding part 222 at both ends in the second direction. The first sliding part 221 is slidably engaged with the first sliding groove 13, and the second sliding part 222 is slidably engaged with the second sliding groove 14.

[0079] Furthermore, such as Figure 13 , Figure 15 , Figure 17 As shown, the first traction section 132 includes a guide section 1321 and a support section 1322. One end of the guide section 1321 is connected to one end of the first push-pull section 131, and the other end is connected to the support section 1322. The guide section 1321 and the first push-pull section 131 are set at an obtuse angle. The support section 1322 is closer to the first tabletop 111 than the first push-pull section 131 and is parallel to the first push-pull section 131. When the first sliding part 221 moves in the guide section 1321, it can move closer to the first tabletop 111. When the end position of the first sliding part 221 is in the support section 1322, the support section 1322 can effectively support the first sliding part 221 at the end position (e.g., ...). Figure 15 , Figure 17 ).

[0080] The second traction section 142 includes an arc segment. One end of the second traction section 142 is connected to one end of the second push-pull section 141, and the other end of the second traction section 142 bends towards the first tabletop 111. When the second sliding part 222 moves along the second traction section 142, it can move closer to the first tabletop 111 under the guidance of the second traction section 142. Furthermore, the second traction section 142 is tangent to the second push-pull section 141, which allows for a smooth transition between the two sections. The second traction section 142 also includes a straight section connected to the end of the arc segment, so that the end of the second traction section 142 can effectively support the second sliding part 222.

[0081] It can be seen that both the first traction section 132 and the second traction section 142 tend to move closer to the first tabletop 111 relative to the first push-pull section 131 and the second push-pull section 141. Therefore, they can guide the first sliding part 221 and the second sliding part 222 to move in the direction of the first tabletop 111, so that the second tabletop 211 can move closer to the spatial plane of the first tabletop 111 and eventually become flush with the first tabletop 111.

[0082] Optionally, the first sliding part 221 and the second sliding part 222 may be a shaft; they may also include components such as rollers and bearings to reduce resistance.

[0083] Figure 19 This is a schematic diagram showing the arrangement of the reset mechanism 6 in one embodiment of this application. (In conjunction with...) Figures 13 to 19 In this embodiment, the end of the second traction section 142 away from the second push-pull section 141 folds back towards the rear end of the second tabletop 2. The pull-out tabletop also includes a reset mechanism 6 connected to the first tabletop 1 and the second tabletop 2. The reset mechanism 6 is used to make the second tabletop 2 tend to retract into the receiving cavity. Since the end of the second traction section 142 away from the second push-pull section 141 folds back towards the rear end of the second tabletop 2, by providing the reset mechanism 6, the second sliding part 222 can be locked at the end of the second traction section 142 (i.e., the end away from the second push-pull section 141), that is, locked at the end position. At this time, the position of the second tabletop 2 is also locked, and the second tabletop 211 and the first tabletop 111 can remain flush. Optionally, the reset mechanism 6 includes a coil spring (such as... Figure 19 (as shown); in other embodiments, the reset mechanism 6 may also include a tension spring, a compression spring, or a driving component such as a motor.

[0084] When it is necessary to retract the second table 2 into the first table 1, the second table 2 can be manually pulled outward first, guiding the second sliding part 222 to move along the second traction section 142 to the second push-pull section 141. After that, the second table 2 can be retracted into the receiving cavity of the first table 1 under the drive of the reset mechanism 6.

[0085] Figure 20 This is a schematic diagram of the support arm 23 in one embodiment of this application. (In conjunction with...) Figure 11 and Figure 20Furthermore, the second tabletop 2 includes a second plate body 21, a sliding arm 22, and a support arm 23. The sliding arm 22 and the support arm 23 are both connected to the same end of the second plate body 21 in the first direction and extend along the first direction. The sliding arm 22 is used for sliding engagement with the first tabletop 1, specifically for sliding engagement with the mating part 12 of the first tabletop 1. The sliding arm 22 and the support arm 23 are located on the side of the first tabletop 1 facing away from the first tabletop 111. By providing the support arm 23, the strength of the second tabletop 2 can be effectively improved, increasing the support area between it and the first tabletop 1, thereby improving the stability of the second tabletop 2 after unfolding. Optionally, the two sliding arms 22 are spaced apart in the second direction, and the support arm 23 is located between the two sliding arms 22. The side of the support arm 23 facing the first tabletop 111 has a clearance groove 231 for avoiding the edge of the first tabletop 1. Optionally, the opening edge of the receiving cavity of the first tabletop 1 has an inwardly folded edge, and the clearance groove 231 can be used to avoid the folded edge. The clearance groove 231 is adjacent to the connecting surface 232 on one side in the first direction, and the clearance groove 231 is adjacent to the supporting surface 233 on the other side in the first direction. The connecting surface 232 is used to connect with the second plate 21, and the supporting surface 233 is used to support the back of the first plate 11 of the first table board 1 and can slide relative to the first plate 11.

[0086] Figure 21 This is a schematic diagram of the support component 24 in a first state in one embodiment of this application; Figure 22 This is a schematic diagram of the support component 24 in a second state in one embodiment of this application; Figure 23 This is a schematic diagram of the support component 24 in a third state in one embodiment of this application; Figure 24 This is a schematic diagram showing how the locking pin 244 locks the sliding support 243 in the support position according to one embodiment of this application. Figures 21 to 24As shown, in an optional embodiment, the pull-out tabletop further includes a support assembly 24. The support assembly 24 includes a first rod 241, a second rod 242, a sliding support 243, and a locking pin 244. One end of the first rod 241 is rotatably connected to the second tabletop 2, and the other end of the first rod 241 is rotatably connected to one end of the second rod 242. The end of the second rod 242 away from the first rod 241 is rotatably connected to the sliding support 243. The sliding support 243 is connected to the side of the second tabletop 2 away from the second tabletop 211, and the sliding support 243 can slide relative to the second tabletop 2 in a first direction. The sliding support 243 has a support position. When the first table 1 is in the exit position and the second tabletop 211 of the second table 2 is pulled out from the receiving cavity, the sliding support 243 can move to the support position. When the sliding support 243 is in the support position, the first rod 241 and the second rod 242 form an angle, and the first rod 241 abuts against the edge of the entrance and exit of the receiving cavity 3. The locking pin 244 is pluggably inserted into the sliding support 243 and is used to lock the sliding support 243 in the support position.

[0087] In this embodiment, a support rail 245 is provided on the back of the second table panel 2, and the sliding support 243 is slidably engaged with the support rail 245. When the second table panel 2 is not pulled out from the first table panel 1, the hinge point between the first rod 241 and the second rod 242 is close to the second table panel 2 and supported on the lower shell 32 of the receiving compartment 3, as shown. Figure 21 As shown. When the hinge point moves out of the entrance / exit of the receiving chamber 3, the first rod 241 and the second rod 242 will fall downwards, and at the same time, the sliding support 243 will slide, as shown. Figure 22 As shown, when the second tabletop 2 is raised and the second tabletop 211 is flush with the first tabletop 111, the sliding support 243 moves to the support position, and the first rod 241 abuts against the edge of the entrance / exit of the containment chamber 3. The locking pin 244 locks the sliding support 243 in the support position. At this time, the first rod 241, the second rod 242, and the second tabletop 2 form a stable triangular structure. The edge of the entrance / exit of the containment chamber 3 can support the first rod 241, thereby improving the reliability of the second tabletop 2 after it is unfolded and increasing its load-bearing capacity.

[0088] In this embodiment, the locking pin 244 can first pass through the hole on the fixing component on the second table 2, and then pass through the pin hole on the sliding support 243, thereby locking the sliding support 243 in the support position.

[0089] Figures 1 to 24The pull-out table in this embodiment can be used in a car, for example, positioned between the glove box and the trim panel above the glove box in the passenger seat area, with the storage compartment 3 fixed relative to the glove box and the trim panel. Optionally, the upper shell 31 and lower shell 32 of the storage compartment 3 can be integrated into relevant parts of the dashboard, or connected to the dashboard as a separate module. In other embodiments, the storage compartment 3 can be omitted, and the first table 1 can be connected to the back of the seat 9 for the convenience of rear passengers.

Figures 25 to 27 As shown, in an optional embodiment, the pull-out tabletop includes a base 7, with the first tabletop 1 directly or indirectly connected to the base 7 and capable of flipping relative to the base 7. Specifically, the pull-out tabletop also includes a bottom shell 8, which is disposed on the side of the second tabletop 2 opposite to the first tabletop 1. The bottom shell 8 and the first tabletop 1 together form a receiving cavity for accommodating the second tabletop 2, and the end of the bottom shell 8 away from the opening of the receiving cavity is rotatably connected to the base 7. In this embodiment, the base 7 can be fixedly disposed behind the seat 9. When not in use, the first tabletop 111 of the first tabletop 1 is in contact with the back of the seat 9, and the position of the first tabletop 1 is locked by a latch 91. When in use, the latch 91 is unlocked, and the first tabletop 1 can be unfolded by flipping downwards. Furthermore, the second tabletop 2 can be pulled out from the first tabletop 1 to increase the tabletop area.

[0091] exist Figures 25 to 27 In this embodiment, two bases 7 can be provided to ensure the reliability of the first tabletop 1. The bottom shell 8 is connected to the base 7 via a pivot 71. In this embodiment, the pull-out tabletop also includes a support arm 23 and a reset mechanism 6, which function as follows: Figures 1 to 24 The supporting arm 23 and the reset mechanism 6 in the illustrated embodiment have similar functions, and will not be described again here.

[0092] In summary, this application provides a pull-out tabletop. The pull-out tabletop includes a first tabletop 1 and a second tabletop 2. The first tabletop 1 has a first tabletop 111, and the second tabletop 2 has a second tabletop 211. The first tabletop 1 forms a receiving cavity with an opening, and at least a portion of the second tabletop 2 is received within the receiving cavity. The second tabletop 2 and the first tabletop 1 are slidably engaged so that the second tabletop 211 can extend and retract from the opening of the receiving cavity along a first direction. One of the first tabletop 1 and the second tabletop 2 is provided with a sliding groove, and the other is provided with a sliding part. The sliding groove includes a push-pull section extending along the first direction and a traction section connected to one end of the push-pull section. The traction section is bent relative to the push-pull section. The sliding part is configured to enter the traction section along the push-pull section during the process of the second tabletop 211 being pulled out of the receiving cavity, and under the guidance of the traction section, bring the second tabletop 211 closer to the spatial plane where the first tabletop 111 is located. By setting a traction section in the chute, the second tabletop 2 can be guided by the traction section to move closer to the spatial plane where the first tabletop 111 is located during the pulling process. This allows the second tabletop 211 to be as flush as possible with the first tabletop 111, reducing the step between the first tabletop 111 and the second tabletop 211 and improving the flatness of the overall tabletop formed by the first tabletop 111 and the second tabletop 211.
