[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] The embodiments of the present application provide a pull-out foldable vehicle-use tablet and a vehicle, which can solve the problems in the related art of complex maze lock structure, large space occupation, and poor locking reliability.

[0042] See also Figures 1 to 4 As shown, the first aspect of the embodiment of the present application provides a pull-out foldable car writing tablet, comprising:

[0043] The writing tablet assembly 10 includes a table mounting frame 11, to which a writing tablet 12 and a folding board 13 are slidably connected. A hinge 14 is provided at one end of the writing tablet 12 for unfolding or folding the folding board 13. When a passenger needs to use the writing tablet 12 and folding board 13, the writing tablet 12 and folding board 13 are slid out of the table mounting frame 11, and the folding board 13 is then rotated 180 degrees about the hinge 14 before unfolding. When the folding board 13 is unfolded, the front surface of the folding board 13 is flush with the front surface of the writing tablet 12. The folding board 13 and the writing tablet 12 together form an item placement platform for passengers to place items such as books, mobile phones, tablets, laptops, and food.

[0044] The handle lock assembly 20 includes a locking tongue 21 that is pivotally connected to the back of the writing board 12 and locks the writing board 12 to the table mounting frame 11, and a handle 22 connected to the locking tongue 21 for unlocking the locking tongue 21 and withdrawing the writing board 12. The locking tongue 21 and the handle 22 are interconnected and pivotally connected to the back of the writing board 12. When the writing board 12 and the folding board 13 are folded together and retracted into the table mounting frame 11, the locking tongue 21 locks the writing board 12 and the folding board 13 to the table mounting frame 11, preventing the writing board 12 and the folding board 13 from accidentally sliding out of the table mounting frame 11 due to bumpy roads.

[0045] The handle 22 is preferably, but not limited to, an annular structure. The handle 22 is connected to the lock tongue 21. When a passenger needs to use the tablet 12, the handle 22 is pressed downward to drive the lock tongue 21 to unlock the tablet 12, allowing the tablet 12 to slide freely relative to the table mounting frame 11. After the lock tongue 21 unlocks the tablet 12, the passenger can continue to pull the handle 22 to slide the tablet 12 and the folding board 13 out of the table mounting frame 11, and then unfold the tablet 12 and the folding board 13 to form an item placement platform.

[0046] The pull-out foldable car writing tablet of the embodiment of the present application adopts a folding structure design of the writing tablet 12 and the folding plate 13 to expand the functional characteristics of the writing tablet 12, so that it can meet more usage scenarios such as dining, computer office, and writing. At the same time, a handle lock assembly 20 is added. The handle lock assembly 20 replaces the maze lock structure used by the existing table board to improve the abnormal unlocking and popping of the table board under extreme road conditions. The handle lock assembly 20 not only uses the handle 22 to unlock the writing tablet 12 with the lock tongue 21, but also can pull the writing tablet 12 and the folding plate 13 out of the table board mounting frame 11 after unlocking the writing tablet 12. This improves the problem of inconvenience for users to operate the writing tablet 12 due to the limited space during the pulling and pulling process, and improves the comfort of the writing tablet 12 when pulling and pulling.

[0047] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a foldable, vehicle-mounted tablet. The handle lock assembly 20 of the foldable, vehicle-mounted tablet further includes a lock support 23 connected to the back of the tablet 12. A rotating shaft 24, rotatably connected to the lock support 23, is provided at the connection between the lock tongue 21 and the handle 22. The lock tongue 21 and the handle 22 rotate about the rotating shaft 24 on the lock support 23. An elastic member 28 is provided on the rotating shaft 24 to drive the lock tongue 21 to lock the tablet 12 to the table mounting frame 11. The elastic member 28 is used to maintain the locking force of the lock tongue 21, preventing the tablet 12 and foldable board 13 from accidentally unlocking and sliding out of the table mounting frame 11 due to bumpy roads.

[0048] In some alternative embodiments: See Figure 4 As shown, an embodiment of the present application provides a foldable, vehicle-use tablet. The lock support 23 of the foldable, vehicle-use tablet includes a mounting plate mounted on the back of the tablet 12 via screws 25. Two lugs for rotatably supporting a shaft 24 are provided at the bottom of the mounting plate, and the two lugs are spaced apart from each other at the bottom of the mounting plate. A shaft hole for inserting the shaft 24 is provided at the connection between the lock tongue 21 and the handle 22. A sound-absorbing pad 26 is provided on the lock support 23, located between the lock tongue 21 and the lock support 23, to eliminate noise generated by collision between the lock tongue 21 and the lock support 23.

[0049] The elastic member 28 is preferably, but not limited to, a torsion spring. The torsion spring is mounted on the rotating shaft 24 and located between the two lugs. One end of the torsion spring abuts against the lock tongue 21, and the other end abuts against the lock support 23. The torsion spring is elastically supported between the lock support 23 and the lock tongue 21, so that the lock tongue 21 rotates toward the table mounting frame 11 to lock the writing board 12 to the table mounting frame 11. After the lock tongue 21 is unlocked by the handle 22, the torsion spring automatically resets the lock tongue 21.

[0050] In some alternative embodiments: See Figure 5 As shown, an embodiment of the present application provides a pull-out foldable car writing tablet, wherein the handle lock assembly 20 of the pull-out foldable car writing tablet further includes a lock buckle 17 fixed to the table mounting frame 11. The lock buckle 17 is vertically connected to the top of the table mounting frame 11, and includes a first guide slope slidably connected to a lock tongue 21, and a first locking surface lockably connected to the lock tongue 21. The lock tongue 21 includes a lock plate fixedly connected to the handle 22, and a lock hook is provided on the lock plate. The lock hook includes a second guide slope slidably connected to the first guide slope, and a second locking surface lockably connected to the first locking surface.

[0051] The lock catch 17 of the present embodiment is fixed to the tabletop mounting bracket 11 to mate with the lock tongue 21. The lock catch 17 and the lock hook are preferably, but not limited to, right-angled triangular structures. The first guide slope of the lock catch 17 and the second guide slope of the lock hook are slidably connected to each other, providing a guide for the lock tongue 21 as it moves toward the lock catch 17, so that the first locking surface of the lock catch 17 and the second locking surface of the lock hook engage with each other to achieve mutual locking.

[0052] See also Figure 5 As shown, when a passenger needs to use the tablet 12 for dining, entertainment, or work, they must first unlock the tablet 12. To unlock the tablet 12, the passenger applies a downward force F1 with one hand to press the handle 22. After the handle 22 rotates approximately 15° about the axis 24, the lock tongue 21 disengages the latch 17 on the table mounting frame 11, effectively unlocking the tablet 12 from the table mounting frame 11. The passenger then applies a backward force F2 to pull on the handle 22, pulling the tablet 12 and folding board 13 out of the table mounting frame 11 until they stop at their maximum travel. Finally, the folding board 13 is opened, completing the steps for using the tablet 12.

[0053] When the passenger has finished using the table, they first flip the folding plate 13 over and fold it to the top of the tablet 12 via the hinge 14. Then, they apply a forward push to the handle 22, sliding the tablet 12 and folding plate 13 toward the table mounting bracket 11. When the hook of the lock tongue 21 comes into contact with the lock catch 17, the first guide slope of the lock catch 17 and the second guide slope of the lock hook slide into contact with each other until the first locking surface of the lock catch 17 and the second locking surface of the lock hook engage, locking the two surfaces. The torsion spring constantly applies a downward rotational torque to the lock tongue 21, allowing it to remain locked with the lock catch 17. This effectively offsets the upward impact load generated when the vehicle encounters road bumps, thereby reducing the risk of the tablet 12 automatically unlocking and popping open.

[0054] In some alternative embodiments: See Figures 6 to 8 As shown, an embodiment of the present application provides a pull-out, foldable writing tablet for use in vehicles. The handle 22 and lock tongue 21 of the pull-out, foldable writing tablet are integrally formed. The handle 22 and lock tongue 21 can be integrally formed from aluminum alloy or injection-molded from nylon plastic. The handle 22 is located on the back of the writing tablet 12 and at least partially extends beyond the periphery of the writing tablet 12. A retaining protrusion 18 is provided on the back of the foldable board 13 near one end of the writing tablet 12, which presses downward on the handle 22 to release the lock tongue 21 from the writing tablet 12.

[0055] When the writing board 12 and the folding board 13 are in use, if the back of the folding board 13 is not provided with a limit protrusion 18 for pressing the handle 22 downward to allow the lock tongue 21 to unlock the writing board 12, it is easy for a passenger to forget to fold and flip the folding board 3 first, or accidentally hit the writing board 12 and the folding board 13, causing the writing board 12 and the folding board 13 to slide directly into the table board mounting frame 11 in the unfolded state, thereby causing the handle lock assembly 20 to accidentally lock the writing board 12. Since the folding board 13 is not folded and retracted at this time, the passenger cannot operate the handle lock assembly 20 to unlock the writing board 12 (such as Figure 7 and Figure 8 shown).

[0056] To address the aforementioned situation where the folding plate 13 is not unfolded and the handle lock assembly 20 is accidentally locked, the present embodiment of the present invention provides a stopper 18 on the back of the folding plate 13 near the end of the writing plate 12, which presses down on the handle 22 to allow the lock tongue 21 to unlock the writing plate 12. When the folding plate 13 is unfolded, the stopper 18 on the back of the folding plate 13 presses down on the handle 22 under the action of the folding plate 13's gravity, causing the lock tongue 21 to tilt upward 15° about the rotation axis 24. Even if the writing plate 12 and folding plate 13 slide into the table mounting frame 11 while unfolded, the lock tongue 21 and the lock catch 17 are unlocked, allowing the writing plate 12 and folding plate 13 to be slid out of the table mounting frame 11 again to fold and flip the folding plate 13.

[0057] In some alternative embodiments: See Figures 6 to 8 As shown, an embodiment of the present application provides a pull-out, foldable writing tablet for use in vehicles. The handle 22 of the pull-out, foldable writing tablet is located on the back of the writing tablet 12 and extends at least partially beyond the periphery of the writing tablet 12. A retaining protrusion 18 is provided on the back of the folding board 13 near one end of the writing tablet 12, which is used to press the handle 22 downward to release the locking tongue 21 from the writing tablet 12. The top of the handle 22 is provided with a raised surface 27 that mates with the retaining protrusion 18 of the folding board 13. When the folding board 13 is unfolded, pressing the handle 22 downward causes the locking tongue 21 to release the writing tablet 12.

[0058] When the writing board 12 and the folding board 13 are in use, if the back of the folding board 13 is not provided with a limiting protrusion 18 for pressing the handle 22 downward to allow the lock tongue 21 to unlock the writing board 12, and the top of the handle 22 is not provided with a raised surface 27 that matches the limiting protrusion 18 of the folding board 13, it is easy for a passenger to forget to fold and flip the folding board 13 first, or accidentally hit the writing board 12 and the folding board 13, causing the writing board 12 and the folding board 13 to slide directly into the table board mounting frame 11 in the unfolded state, thereby causing the handle lock assembly 20 to accidentally lock the writing board 12. Since the folding board 13 is not folded and retracted at this time, the passenger cannot operate the handle lock assembly 20 to unlock the writing board 12 (such as Figure 7 and Figure 8shown).

[0059] Two limiting protrusions 18 are added to the back of the folding plate 13. The limiting protrusions 18 are 6mm high. The raised surface 27 of the handle 22 cooperates with the limiting protrusions 18. The raised surface 27 is 5.1mm high. After the folding plate 13 is opened 180° and flipped, the limiting protrusions 18 press against the raised surface 27 of the handle 22. Under the action of the folding plate 13's gravity, the limiting protrusions 18 exert an operating force similar to the pressing force F1 on the raised surface 27 of the handle 22, causing the lock tongue 21 to rotate upward 15° about the rotation axis 24. At this time, if the folding plate 13 and the writing board 12 slide abnormally back to the table mounting frame 11, the lock tongue 21 and the lock catch 17 on the table mounting frame 11 will remain separated, thereby preventing the handle lock assembly 20 from being locked unnecessarily and eliminating the aforementioned problem.

[0060] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a foldable, retractable writing tablet for use in a vehicle. A slide rail 15 is fixedly connected to the top of a table mounting frame 11 of the foldable writing tablet. Two slide rails 15 are provided, which are parallel to each other and spaced apart between the writing tablet 12 and the table mounting frame 11. The writing tablet 12 extends or retracts into the table mounting frame 11 along the length of the slide rails 15. The table mounting frame 11 is an injection-molded part, and a sliding space is provided at the top of the table mounting frame 11 to accommodate the writing tablet 12 and the foldable board 13.

[0061] Both slide rails 15 include a static slide rail fixedly connected to the tabletop mounting frame 11, and a dynamic slide rail fixedly connected to the writing board 12, and the dynamic slide rail and the static slide rail are slidably connected to each other. A limiting component is provided at both ends of the static slide rail, and the limiting component is used to limit the travel of the dynamic slide rail out of the static slide rail. The limiting component is used to limit the travel of the dynamic slide rail to prevent the dynamic slide rail from escaping from the static slide rail. A retaining component (not shown in the figure) is provided on the static slide rail to keep the dynamic slide rail on the static slide rail after it is extended. There is a damping force of 30-40N between the retaining component and the dynamic slide rail. The retaining component can be made of spring steel balls or damping rubber blocks. The spring steel balls or damping rubber blocks are fixed to the static slide rail. When the dynamic slide rail is extended, the spring steel balls or damping rubber blocks squeeze the dynamic slide rail to keep it at its current extended length.

[0062] In this embodiment of the present application, a retaining member is provided on the static rail to maintain the movable rail on the static rail after extension. Once the writing board 12 slides out of the table mounting frame 11, the retaining member automatically retracts the writing board 12 back into the table mounting frame 11, unaffected by road bumps or normal braking. Furthermore, a damping force of 30-40N is provided between the retaining member and the movable rail. In the event of a dangerous accident such as a rear-end collision or emergency braking, the retaining member immediately fails upon collision with the writing board 12 and folding board 13, causing the writing board 12 and folding board 13 to slide rapidly back into the table mounting frame 11, protecting the passenger from injury caused by the impact of the writing board 12 and folding board 13.

[0063] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a pull-out, foldable writing tablet for use in vehicles. The table mounting frame 11 of the pull-out, foldable writing tablet is provided with a position-limiting buffer 16 that drives the writing tablet 12 to slide out of the table mounting frame 11 along the direction of the slide rail 15. A sliding opening is provided at one end of the table mounting frame 11, through which the writing tablet 12 and folding plate 13 extend. The position-limiting buffer 16 is located at the end of the table mounting frame 11 away from the sliding opening. The position-limiting buffer 16 not only limits the position of the writing tablet 12 when it slides into the table mounting frame 11, but also provides thrust for the writing tablet 12 to slide out of the table mounting frame 11 after the handle lock assembly 20 unlocks the writing tablet 12, thereby ejecting the writing tablet 12 from the table mounting frame 11.

[0064] A second aspect of an embodiment of the present application provides a vehicle, including:

[0065] An instrument panel assembly includes an instrument panel frame, an instrument panel connected to the instrument panel frame, an opening and an outer cover closing the opening on the instrument panel; and a pull-out foldable vehicle writing tablet as described in any of the above embodiments, wherein the table mounting frame 11 of the pull-out foldable vehicle writing tablet is fixed to the instrument panel frame or the instrument panel; the writing tablet 12 and folding board 13 of the pull-out foldable vehicle writing tablet slide out of the instrument panel through the opening.

[0066] How it works

[0067] An embodiment of the present application provides a pull-out foldable vehicle writing tablet and a vehicle. Since the pull-out foldable vehicle writing tablet of the present application is provided with a writing tablet assembly 10, the writing tablet assembly 10 includes a table board mounting frame 11, on which a writing tablet 12 and a folding board 13 are slidably connected, and one end of the writing tablet 12 is provided with a hinge 14 for unfolding or folding the folding board 13; a handle lock assembly 20, which includes a lock tongue 21 that is rotatably connected to the back side of the writing tablet 12 and locks the writing tablet 12 on the table board mounting frame 11, and a handle 22 connected to the lock tongue 21 for unlocking the lock tongue 21 and pulling out the writing tablet 12.

[0068] Therefore, the pull-out foldable car writing tablet of the present application adopts the folding structure design of the writing tablet 12 and the folding plate 13 to expand the functional characteristics of the writing tablet 12, so that it can meet more usage scenarios such as dining, computer office, and writing. At the same time, a handle lock assembly 20 is added. The handle lock assembly 20 replaces the maze lock structure used by the existing table board to improve the abnormal unlocking and popping of the table board under extreme road conditions. The handle lock assembly 20 not only uses the handle 22 to unlock the writing tablet 12 with the lock tongue 21, but also can pull the writing tablet 12 and the folding plate 13 out of the table board mounting frame 11 after unlocking the writing tablet 12, thereby improving the problem of inconvenience for users to operate the writing tablet 12 due to the limited space during the pulling and pulling process, and improving the comfort of the writing tablet 12 when pulling and pulling.
