[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.

[0035] The terms "comprising" and "having" and any variations thereof in the description and claims of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0036] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "arranged", "installed", "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or connected by contact or indirectly through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] A tabletop device 2, as Figures 1-14 shown, includes a fixing member 30, a tabletop 50, a link assembly 10 and a shielding assembly 20. The fixing member 30 is used for fixing at the installation location to be installed. An accommodation groove 41 is formed on the tabletop 50, and the link assembly 10 is connected to the tabletop 50 and the fixing member 30 so that the tabletop 50 can be flipped between a folded position and an open position relative to the fixing member 30. Further, one end of the shielding assembly 20 is movably connected to the link assembly 10, and the other end of the shielding assembly 20 is movably connected to the tabletop 50, and the link assembly 10 can drive the shielding assembly 20 to move relative to the tabletop 50. Thus, when the tabletop 50 is in the folded position, the link assembly 10 and the shielding assembly 20 are folded and close together, and the shielding assembly 20 is received in the accommodation groove 41 of the tabletop 50, making the structure of the tabletop device 2 more compact. When the tabletop 50 is in the open position, the link assembly 10 and the shielding assembly 20 are unfolded, and at least part of the link assembly 10 and the shielding assembly 20 can shield the accommodation groove 41, which helps to prevent foreign objects from falling into the accommodation groove 41 and reduces the risk of the tabletop device 2 getting stuck or even unable to be used normally due to foreign objects falling in.

[0038] In at least one embodiment, as Figure 2 shown, the tabletop 50 includes a housing 53, a mounting bracket 54 provided inside the housing 53, and a movable member 40 fixed to the mounting bracket 54. An accommodation groove 41 is provided on the movable member 40; the link assembly 10 and the shielding assembly 20 are connected to the movable member 40 and thus can be connected to the tabletop 50. It should be understood that the mounting bracket 54 and the movable member 40 can be implemented with materials having higher structural strength, such as metals, alloys, etc., to improve the structural strength of the tabletop 50; the housing 53 can be implemented with plastics, which is beneficial to be formed by injection molding process to reduce production costs.

[0039] In at least one embodiment, the link assembly 10, the shielding assembly 20, the fixing member 30, and the movable member 40 together form a flipping mechanism 1. The tabletop device 2 includes a tabletop 50 and two flipping mechanisms 1. Specifically, the tabletop 50 has opposite first side portion 51 and second side portion 52. The movable member 40 of one flipping mechanism 1 is fixed to the first side portion 51 of the tabletop 50, and the movable member 40 of the other flipping mechanism 1 is fixed to the second side portion 52 of the tabletop 50, so as to reliably support the tabletop 50. It should be understood that the upper surface of the movable member 40 is flush with or approaches to be flush with the upper surface of the tabletop 50. When the tabletop 50 is opened relative to the installation location, at least part of the link assembly 10 of the flipping mechanism 1 and the shielding assembly 20 can shield the receiving groove 41 of the movable member 40, so that the use surface of the tabletop device becomes more flat and beautiful, and it is beneficial to avoid foreign objects from falling into the receiving groove 41, reducing the risk of the tabletop device 2 jamming or even being unable to be used normally due to the falling of foreign objects.

[0040] It is worth mentioning that the installation location includes but is not limited to the backrest of an automotive seat, and the present application does not make specific limitations thereto.

[0041] In some embodiments, as Figures 4-14 shown, the link assembly 10 includes a first link 11. One end of the first link 11 is hinged to the fixing member 30, and the other end of the first link 11 is hinged to the tabletop 50, so that the tabletop 50 is adapted to flip between a folded position and an open position relative to the fixing member 30. Further, the shielding assembly 20 includes a first shielding member 21 and a second shielding member 22. The first shielding member 21 has a first end 211 and a second end 212 which are oppositely arranged. The second shielding member 22 has a third end 221 and a fourth end 222 which are oppositely arranged. Among them, the first end 211 is hinged to the first link 11, the second end 212 is hinged to the third end 221, and the fourth end 222 is hinged to the tabletop 50. That is to say, the first link 11 is adapted to rotate relative to the tabletop 50, and the second shielding member 22 is also adapted to rotate relative to the tabletop 50. The first shielding member 21 is connected between the first link 11 and the second shielding member 22 to be adapted to rotate and / or translate relative to the tabletop 50.

[0042] Specifically, as Figures 4-7As shown in the figure, when the tabletop 50 is in the folded position, the first link 11 and the second shielding member 22 are folded and close to the same side of the first shielding member 21. Specifically, the first shielding member 21 and the second shielding member 22 are received in the receiving groove 41. The first link 11 and the second shielding member 22 are folded and close to the side of the first shielding member 21 facing the fixing member 30, and the second shielding member 22 is located between the first link 11 and the second shielding member 22. It should be understood that compared with the first link 11 and the second shielding member 22 being folded and close to both sides of the first shielding member 21 respectively, in this embodiment, the first link 11 and the second shielding member 22 are folded and close to the same side of the first shielding member 21, which is beneficial to reducing the depth of the receiving groove 41 and further reducing the thickness of the tabletop 50.

[0043] As Figures 8-11 shown in the figure, when the tabletop 50 is in the open position, the first link 11, the first shielding member 21 and the second shielding member 22 are unfolded to shield the receiving groove 41. That is to say, at least part of the first link 11, the first shielding member 21 and the second shielding member 22 are arranged in sequence in the receiving groove 41, and the upper surfaces of at least part of the first link 11, the first shielding member 21 and the second shielding member 22 are flush or approximately flush with the upper surface of the tabletop 50, so that the use surface of the tabletop 50 is flat and beautiful, convenient to use, and is beneficial to preventing foreign objects from falling into the receiving groove 41.

[0044] In some embodiments, as Figures 4-12 shown in the figure, the first link 11 includes a first fixed end 111 and a first movable end 112 which are oppositely arranged, wherein the first fixed end 111 is hinged to the fixing member 30, and the first movable end 112 is hinged to the tabletop 50. Further, the first link 11 includes a connecting section 113, a shielding section 114 and a first receiving section 115 which are arranged in sequence from the first fixed end 111 to the first movable end 112. The connecting section 113 and the first receiving section 115 extend to the opposite sides of the shielding section 114 respectively. The connecting section 113 is hinged to the fixing member 30, and the first receiving section 115 is hinged to the tabletop 50. Thus, when the tabletop 50 is in the open position, the tabletop 50 is arranged at an angle with the fixing member 30; when the tabletop 50 is in the folded position, the tabletop 50 is arranged parallel or approximately parallel to the fixing member 30. The first end 211 of the first shielding member 21 is hinged to the first receiving section 115, so that the first link 11 can drive the first shielding member 21 to move relative to the tabletop 50.

[0045] Furthermore, the first receiving section 115 has a first receiving groove 1151 with an opening facing the first shielding member 21. When the tabletop 50 is in the open position, as Figures 4-7As shown, the shielding section 114 shields the receiving groove 41; the connecting section 113 bends and extends from the shielding section 114 towards the fixing member 30 and is hinged to the fixing member 30; the first receiving section 115 is received in the receiving groove 41, and a part of the first shielding member 21 is located above the first receiving section 115 to shield the first receiving section 115. It should be understood that a part of the first shielding member 21 is located at the opening of the first receiving groove 1151, so that the upper surface of the first shielding member 21 is flush with or approaches the upper surface of the shielding section 114 of the first connecting rod 11. Thus, the first shielding member 21 shields the receiving groove 41 and reduces the gap between the shielding section 114 of the first connecting rod 11 and the first shielding member 21.

[0046] When the tabletop 50 is in the folded position, as Figures 8-11 shown, the first connecting rod 11 and the first shielding member 21 are folded and close to each other, and a part of the first shielding member 21 is received in the first receiving groove 1151. That is to say, during the process of the tabletop 50 flipping from the open position to the folded position, a part of the first shielding member 21 is adapted to move from the opening of the first receiving groove 1151 into the first receiving groove 1151, and at the same time, the first shielding member 21 moves from the notch of the receiving groove 41 to the bottom of the receiving groove 41. Until the tabletop 50 is in the folded position, a part of the first shielding member 21 is received at the bottom of the first receiving groove 1151, and the first shielding member 21 is received in the receiving groove 41, making the structure among the first connecting rod 11, the first shielding member 21 and the tabletop 50 more compact, which is beneficial for the tabletop 50 to approach the fixing member 30 and reduces the distance between the tabletop 50 and the fixing member 30.

[0047] In some embodiments, as Figure 6 、 Figure 10 and Figure 12 shown, the first receiving section 115 includes a main body portion 1152 and a connecting portion 1154. The main body portion 1152 bends and extends from the shielding section 114 to form the first receiving groove 1151. One end of the main body portion 1152 far from the shielding section 114 has a first hinge structure 1153 and is hinged to the tabletop 50. Further, the connecting portion 1154 is connected to one end of the main body portion 1152 far from the shielding section 114 and extends towards the shielding section 114. One end of the connecting portion 1154 far from the main body portion 1152 has a second hinge structure 1155 and is hinged to the first shielding member 21.

[0048] It should be understood that as Figure 10As shown, the main body portion 1152 bends and extends downward from the shielding section 114 to the lower side of the first shielding member 21, and the connecting portion 1154 extends toward the shielding section 114, such that the second hinge structure 1155 is disposed close to the opening of the first receiving groove 1151. Thus, when the tabletop 50 is in the open position, the first receiving section 115 is received in the receiving groove 41, and a part of the first shielding member 21 shields the opening of the first receiving groove 1151, that is, shields the receiving groove 41, so as to reduce the gap between the shielding section 114 of the first link 11 and the first shielding member 21. When the tabletop 50 is in the folded position, as Figure 5 and Figure 6 shown, a part of the first shielding member 21 is received in the first receiving groove 1151, and can approach the connecting portion 1154. At the same time, at least a part of the first shielding member 21 and the first receiving section 115 are received in the receiving groove 41, which is beneficial for the tabletop 50 to be closer to the fixing member 30.

[0049] In some embodiments, as Figure 6 and Figure 10 shown, the first shielding member 21 includes a first branch section 213 and a main trunk section 214 connected in sequence. A fifth hinge structure 216 is provided between the first branch section 213 and the main trunk section 214, and can be hinged to the second hinge structure 1155 of the first link 11. In at least one embodiment, both the second hinge structure 1155 and the fifth hinge structure 216 are implemented as holes and are connected by a shaft pin, thereby reducing the processing difficulty of the first shielding member 21 and the first link 11, and reducing the production cost of the tabletop device 2.

[0050] Furthermore, as Figure 7 and Figure 11 shown, a first rotation axis is defined between the fifth hinge structure 216 and the second hinge structure 1155. It should be understood that when the first link 11 rotates relative to the tabletop 50, the first rotation axis moves along the virtual circle O4 in the figure, and at the same time, the first branch section 213 of the first shielding member 21 rotates around the first rotation axis. As Figure 13 shown, the distance from the end of the first branch section 213 far from the main trunk section 214 to the first rotation axis is denoted as L1; as Figure 11 shown, at least a part of the groove wall of the first receiving groove 1151 is arc-shaped, and the center of the first virtual circle O1 where it is located is at the first rotation axis. The radius of the first virtual circle O1 is denoted as R1, where R1 > L1, which is beneficial to avoid interference between the first branch section 213 and the groove wall of the first receiving groove 1151, so that the first branch section 213 can smoothly move in the first receiving groove 1151.

[0051] In some embodiments, as Figures 4-11 , and Figure 14As shown, the second shielding member 22 includes a connected covering section 223 and a second receiving section 225. Among them, one end of the covering section 223 away from the second receiving section 225 has a third hinge structure 224, which is hinged to the tabletop 50. Further, the second receiving section 225 is hinged to the second end 212 of the first shielding member 21, so that the first shielding member 21 can drive the second shielding member 22 to move relative to the tabletop 50.

[0052] Furthermore, the second receiving section 225 has a second receiving groove 2251 with an opening facing the first shielding member 21. When the tabletop 50 is in the open position, as Figures 4-7 shown, the covering section 223 can shield the receiving groove 41; a part of the first shielding member 21 is located above the second receiving section 225 and can shield the second receiving section 225. It should be understood that a part of the first shielding member 21 is located at the opening of the second receiving groove 2251, so that the upper surface of the first shielding member 21 is flush or approximately flush with the upper surface of the covering section 223 of the second shielding member 22. Thus, the first shielding member 21 can shield the receiving groove 41 and reduce the gap between the first shielding member 21 and the covering section 223 of the second shielding member 22.

[0053] When the tabletop 50 is in the folded position, as Figures 8-11 shown, the first shielding member 21 and the second shielding member 22 are folded and close together. A part of the first shielding member 21 is received in the second receiving groove 2251, and the second shielding member 22 is received in the receiving groove 4l. That is to say, during the process of the tabletop 50 flipping from the open position to the folded position, a part of the first shielding member 21 is adapted to move from the opening of the second receiving groove 2251 into the second receiving groove 2251, and at the same time, the first shielding member 21 moves from the notch of the receiving groove 41 to the bottom of the receiving groove 41. The second shielding member 22 rotates around the third hinge structure 224 from the notch of the receiving groove 41 to the bottom of the receiving groove 41. Until the tabletop 50 is in the folded position, a part of the first shielding member 21 is received at the bottom of the second receiving groove 2251, and the first shielding member 21 and the second shielding member 22 are both received in the receiving groove 41, making the structure between the first shielding member 21, the second shielding member 22 and the tabletop 50 more compact, which is beneficial for the tabletop 50 to approach the fixing member 30 and reduce the distance between the tabletop 50 and the fixing member 30.

[0054] In some embodiments, as Figure 6 、 Figure 10 and Figure 14As shown, the second receiving section 225 includes a base portion 2252 and an extension portion 2253. Among them, the base portion 2252 extends bendably from the covering section 223 to form a second receiving groove 2251. Further, the extension portion 2253 is connected to one end of the base portion 2252 away from the covering section 223 and extends toward the covering section 223. One end of the extension portion 2253 away from the base portion 2252 has a fourth hinge structure 2254, which can be hinged to the first shielding member 21.

[0055] It should be understood that, as Figure 10 shown, the base portion 2252 extends bendably downward from the covering section 223 to below the first shielding member 21, and the extension portion 2253 extends toward the covering section 223, so that the fourth hinge structure 2254 is located at the opening of the second receiving groove 2251. Thus, when the tabletop 50 is in the open position, the second receiving section 225 is received in the receiving groove 41, and a part of the first shielding member 21 can shield the opening of the second receiving groove 2251, that is, shield the receiving groove 41, so as to reduce the gap between the first shielding member 21 and the covering section 223 of the second shielding member 22. When the tabletop 50 is in the folded position, as Figure 5 and Figure 6 shown, a part of the first shielding member 21 is received in the second receiving groove 2251 and can be close to the extension portion 2253. At the same time, the first shielding member 21 and the second shielding member 22 are received in the receiving groove 41, so that the tabletop 50 is closer to the fixing member 30.

[0056] In some embodiments, as Figure 6 and Figure 10 shown, the first shielding member 21 includes a main trunk section 214 and a second branch section 215 connected in sequence. A sixth hinge structure 217 is provided between the main trunk section 214 and the second branch section 215, which can be hinged to the fourth hinge structure 2254 of the second shielding member 22. In at least one embodiment, both the fourth hinge structure 2254 and the sixth hinge structure 217 are implemented as holes and are connected by a shaft pin, thereby reducing the processing difficulty of the first shielding member 21 and the second shielding member 22 and reducing the production cost of the tabletop device 2.

[0057] Further, as Figure 7 and Figure 11 shown, a second rotation axis is defined between the sixth hinge structure 217 and the fourth hinge structure 2254. It should be understood that when the second shielding member 22 rotates relative to the tabletop 50, the second rotation axis moves along the virtual circle O5 in the figure, and at the same time, the second branch section 215 of the first shielding member 21 rotates around the second rotation axis. As Figure 13 shown, the distance from one end of the second branch section 215 away from the main trunk section 214 to the first rotation axis is denoted as L2; as Figure 11As shown, at least part of the groove wall of the second receiving groove 2251 is arc-shaped, and the center of the second virtual circle O2 where it is located is on the second rotation axis. The radius of the second virtual circle O2 is denoted as R2, where R2 > L2, which helps to avoid interference between the second branch segment 215 and the groove wall of the second receiving groove 2251, so that the second branch segment 215 can move smoothly in the second receiving groove 2251.

[0058] In some embodiments, as Figure 13 shown, the first shielding member 21 includes a first branch segment 213, a main trunk segment 214, and a second branch segment 215 arranged in sequence. The length of the first branch segment 213 is denoted as X1, the length of the main trunk segment 214 is denoted as X2, and the length of the second branch segment 215 is denoted as X3. Among them, X2 > X1 > X3. It should be understood that the length of the main trunk segment 214 is relatively long, while the lengths of the first branch segment 213 and the second branch segment 215 are relatively short, which helps to avoid making the first receiving groove 1151 and the second receiving groove 2251 too large in order to avoid the first branch segment 213 and the second branch segment 215, that is, it helps to avoid R1 and R2 from being too large, so as to reduce the occupied space of the first receiving segment 115 and the second receiving segment 225 in the receiving groove 41.

[0059] Furthermore, as Figure 11 shown, during the process of the tabletop 50 flipping from the open position to the folded position, the first link 11 rotates clockwise around the center of the virtual circle O4, that is, the first link 11 rotates out of the receiving groove 41, while the second shielding member 22 rotates counterclockwise around the center of the virtual circle O5, that is, the second shielding member 22 rotates into the receiving groove 41. Therefore, the main factor affecting the depth of the receiving groove 41 is the size of the second shielding member 22. Specifically, as Figure 11 shown, the distance from the rotation axis of the second shielding member 22 relative to the tabletop 50 to the farthest point on the second shielding member 22 is denoted as R3, that is, the second shielding member 22 moves within the virtual circle O3 with a radius of R3. It should be understood that the depth of the receiving groove 41 needs to be greater than R3. In this embodiment, the length X3 of the second branch segment 215 is relatively small, so as to reduce R3, further reduce the depth of the receiving groove 41, and thus reduce the thickness of the tabletop 50.

[0060] In other embodiments, as Figure 3 shown, the shielding assembly 20 is implemented as a whole. One end of the shielding assembly 20 is hinged to the first link 11, and the other end of the shielding assembly 20 is adapted to move along the sliding groove on the tabletop 50. That is to say, through the cooperation of the first link 11 and the sliding groove, the movement trajectory of the shielding assembly 20 can be restricted. It should be understood that by implementing the shielding assembly 20 as a whole, the number of parts of the tabletop device 2 can be reduced, thereby reducing the production cost and assembly difficulty of the tabletop device 2.

[0061] It is worth mentioning that, as Figure 6As shown, the shielding assembly 20 is implemented as a first shielding member 21 and a second shielding member 22. The second shielding member 22 can not only cooperate with the first link 11 to limit the movement trajectory of the first shielding member 21, but also the covering section 223 of the second shielding member 22 can shield the receiving groove 41. In addition, when the tabletop 50 is in the folded position, the first link 11 and the second shielding member 22 are folded and close to the same side of the first shielding member 21, making the structure of the tabletop device 2 more compact, thereby reducing the depth and length of the receiving groove 41 and further reducing the thickness of the tabletop 50.

[0062] In some embodiments, as Figure 4 and Figure 8 shown, the link assembly 10 further includes a second link 12. The second link 12 includes a second fixed end 121 and a second movable end 122 which are oppositely arranged. The second fixed end 121 is hinged to the fixing member 30 and is spaced from the first fixed end 111 of the first link 11, and the second movable end 122 is hinged to the tabletop 50 and is spaced from the first movable end 112 of the first link 11. As Figure 4 and Figure 5 shown, when the tabletop 50 is in the folded position, the first link 11 and the second link 12 can be arranged side by side and close to each other to make the tabletop 50 close to the fixing member 30; as Figure 8 and Figure 9 shown, when the tabletop 50 is in the open position, the second movable end 122 of the second link 12 can abut against the lower part of the shielding section 114 of the first link 11, so that the tabletop 50 can be supported and positioned through the cooperation of the first link 11 and the second link 12.
