[0044] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0045] As Figure 1 and Figure 2 shown, in an embodiment, the connection structure 100 includes a support assembly 10 and a mounting assembly 20; wherein, the support assembly 10 and the mounting assembly 20 are connected. When the connection structure 100 is applied to a vehicle, the support assembly 10 can be mounted on the vehicle seat, and a table board 200 can be mounted on the mounting assembly 20.

[0046] As Figure 2As shown in the figure, the support assembly 10 includes a mounting base 1, a first rod 2, and a second rod 3. Among them, the first rod 2 is rotatably connected to the mounting base 1 around a first axis, the first rod 2 is rotatably connected to the mounting assembly 20 around a second axis, the second rod 3 is rotatably connected to the mounting base 1 around a third axis, and the second rod 3 is rotatably connected to the mounting assembly 20 around a fourth axis, so that the mounting base 1, the first rod 2, the second rod 3, and the mounting assembly 20 form a four-bar mechanism. In the arrangement direction of the first rod 2 and the second rod 3, the first rod 2 and the second rod 3 can be in contact with each other. The connection position of at least one of the first rod 2 and the second rod 3 on the mounting assembly 20 is adjustable, so that the contact positions of the first rod 2 and the second rod 3 are different.

[0047] In an application scenario, the first rod 2 is located below the second rod 3. When the first rod 2 and the second rod 3 are in contact with each other, the table board 200 is in the unfolded state. When the table board 200 is in the unfolded state, when the table board 200 is pressed downward, the table board 200 will not rotate. When the table board 200 is in the unfolded state, when the table board 200 is lifted upward, it can drive the four-bar mechanism to rotate, so that the table board 200 rotates to the folded state.

[0048] In this embodiment, the connection position of at least one of the first rod 2 and the second rod 3 on the mounting assembly 20 is adjustable, so that the contact positions of the first rod 2 and the second rod 3 are different, and thus the inclination angle of the mounting assembly 20 is different. In this way, the inclination angle of the table board 200 mounted on the mounting assembly 20 is also different. During use, the mounting positions of the first rod 2 and / or the second rod 3 on the mounting assembly 20 can be adjusted according to requirements to adjust the unfolding angle of the table board 200, so that the inclination angle of the table board 200 meets the requirements.

[0049] It should be noted that the structures of the mounting base 1, the first rod 2, and the second rod 3 can adopt existing designs. In addition, the mounting base 1, the first rod 2, the second rod 3, and the mounting assembly 20 form a four-bar to realize the principle of driving the table board 200 to rotate, fold, and unfold, which is an existing technology. On this basis, in this embodiment, the mounting positions of the first rod 2 and / or the second rod 3 on the mounting assembly 20 are designed to be adjustable, so as to realize the adjustable inclination angle of the table board 200, so that the inclination angle of the table board 200 after unfolding is not limited to the inclination angle of the front row seats, and the rear row occupants can adjust the inclination angle of the table board 200 after unfolding according to their actual use requirements.

[0050] Among them, the first rod 2 can rotate relative to the mounting base 1 around the first axis, the first rod 2 can rotate relative to the mounting assembly 20 around the second axis, the second rod 3 can rotate relative to the mounting base 1 around the third axis, and the second rod 3 can rotate relative to the mounting assembly 20 around the fourth axis. The first axis, the second axis, the third axis, and the fourth axis can be parallel to each other, or at least two of the first axis, the second axis, the third axis, and the fourth axis can be non-parallel.

[0051] As Figure 2 shown, in one embodiment, the mounting assembly 20 includes an adjusting member 4; both the first rod 2 and the second rod 3 are rotatably connected to the adjusting member 4. The mounting assembly 20, the mounting base 1, the first rod 2, and the second rod 3 form a four-bar mechanism, which actually means that the adjusting member 4, the mounting base 1, the first rod 2, and the second rod 3 form a four-bar mechanism. The mounting positions of the first rod 2 and / or the second rod 3 on the mounting assembly 20 are adjustable, which actually means that their mounting positions on the adjusting member 4 are adjustable.

[0052] As Figures 2 to 4 shown, in one embodiment, the mounting position of the first rod 2 on the adjusting member 4 is adjustable. Among them, the adjusting member 4 and the first rod 2 are connected by a first connecting shaft 5, so as to realize the relative rotation of the first rod 2 and the adjusting member 4 around the second axis. In addition, a plurality of limiting holes 41 are provided on the adjusting member 4, and the first connecting shaft 5 can be installed in different limiting holes 41 to realize the installation of the first rod 2 at different positions on the adjusting member 4. In this embodiment, the connection position of the second rod 3 on the adjusting member 4 can be non-adjustable or adjustable.

[0053] In addition, the arrangement direction of each limiting hole 41 intersects with the axis of the first connecting shaft 5. Preferably, the arrangement direction of each limiting hole 41 is perpendicular to the axis of the first connecting shaft 5. Among them, the limiting holes 41 can be arranged at intervals along the length direction of the adjusting member 4, and the first rod 2 and the second rod 3 are respectively connected to different positions in the length direction of the adjusting member 4. It should be noted that the axis of the first connecting shaft 5 is the second axis.

[0054] As Figure 3 shown, in one embodiment, the first connecting shaft 5 includes a first connecting portion 51 and a second connecting portion 52; the first rod 2 is connected to the first connecting portion 51; the first connecting portion 51 and the second connecting portion 52 are connected, and in the axial direction of the first connecting shaft 5, the second connecting portion 52 can approach or move away from the first connecting portion 51 to realize withdrawing from or extending into the limiting hole 41.

[0055] By extending the second connecting portion 52 into different limiting holes 41, the first rod 2 can be installed at different positions on the adjusting member 4. Through the setting of this embodiment, the first rod 2 can be conveniently installed at different positions on the adjusting member 4. In addition, in this embodiment, the second connecting portion 52 can be driven manually to extend into or withdraw from the limiting hole 41. In addition, through the cooperation of the first connecting portion 51 and the second connecting portion 52, the force transmission between the first rod 2 and the adjusting member 4 can also be realized.

[0056] In one embodiment, the first connecting portion 51 and the second connecting portion 52 can rotate relative to each other about the axis of the first connecting shaft 5; by arranging the first connecting portion 51 and the second connecting portion 52 to be able to rotate relative to each other about the second axis, the first rod 2 and the adjusting member 4 can be rotated relative to the second axis. In this embodiment, whether the second connecting portion 52 and the adjusting member 4 can rotate relative to each other about the second axis or not, the first rod 2 and the adjusting member 4 can be rotated relative to the second axis, which can facilitate the assembly of components such as the second connecting portion 52 and the adjusting member 4.

[0057] In one embodiment, when the second connecting portion 52 approaches the first connecting portion 51, it can withdraw from the limiting hole 41; when the second connecting portion 52 moves away from the first connecting portion 51, it can extend into the limiting hole 41. In addition, the first connecting portion 51 and the first rod 2 can rotate about the second axis. At this time, a first connecting hole is provided on the first rod 2, and the first connecting portion 51 is inserted into the first connecting hole to achieve the rotational connection between the two.

[0058] As Figure 3 shown, the first connecting portion 51 includes a first resisting member 511 and a rotating shaft 512. The first resisting member 511 is connected to one end of the rotating shaft 512. The axis of the rotating shaft 512 is coaxial with the second axis. The rotating shaft 512 is inserted into the first connecting hole of the first rod 2. The first resisting member 511 can abut against the first rod 2 to limit the displacement of the rotating shaft 512 on the second axis. In addition, a second resisting member is also provided on the rotating shaft 512. In the extending direction of the second axis, the second resisting member and the first resisting member 511 are respectively located on both sides of the first rod 2. When the rotating shaft 512 moves along the direction from the second resisting member to the first resisting member 511, the second resisting member can abut against the first rod 2. The first resisting member 511 and the second resisting member can prevent the rotating shaft 512 from disengaging from the first rod 2.

[0059] As Figure 3 shown, in one embodiment, a guiding column 53 is provided on the first connecting portion 51, and a guiding hole 54 is provided on the second connecting portion 52. The guiding column 53 is located in the guiding hole 54; the guiding hole 54 cooperates with the guiding column 53 to guide the movement of the second connecting portion 52 along the extending direction of the second axis. In addition, after assembly, the guiding column 53 always remains in the guiding hole 54. Among them, the axes of both the guiding column 53 and the guiding hole 54 can be coaxial with the second axis.

[0060] As Figure 3 shown, the first connecting shaft 5 further includes a first elastic member 55. When the second connecting portion 52 moves relative to the first connecting portion 51 on the second axis, it can apply a force to the first elastic member 55 to cause the first elastic member 55 to elastically deform.

[0061] Specifically, when the second connecting portion 52 moves relative to the first connecting portion 51 along the second axis to withdraw from the limiting hole 41, the second connecting portion 52 can apply a force to the first elastic member 55 to cause elastic deformation of the first elastic member 55. The first elastic member 55 mainly plays a role of buffering and supporting to avoid rigid collision between the first connecting portion 51 and the second connecting portion 52; in addition, the first elastic member 55 can also prevent the first connecting portion 51 and the second connecting portion 52 from shaking.

[0062] In one embodiment, the first elastic member 55 is disposed in the guiding hole 54 and sleeved on the guiding post 53. Additionally, the first elastic member 55 can be compressed between the first connecting portion 51 and the second connecting portion 52.

[0063] In one embodiment, the diameter of the first connecting portion 51 is larger than the diameter of the guiding post 53, a stepped structure is formed between the guiding post 53 and the first connecting portion 51, the guiding hole 54 can be a blind hole, one end of the first elastic member 55 abuts against the bottom surface of the guiding hole 54, and the other end of the first elastic member 55 abuts against the first connecting portion 51. Among them, the first elastic member 55 can be a helical spring or the like.

[0064] As Figure 2 and Figure 5 shown, in one embodiment, the mounting assembly 20 further includes a transmission member 6; the transmission member 6 is connected to the adjusting member 4; the transmission member 6 can rotate synchronously with the adjusting member 4 around the second axis, and the transmission member 6 can move relative to the adjusting member 4 in the extending direction of the second axis. The second connecting portion 52 is connected to the transmission member 6 and can move relative to the transmission member 6 along the arrangement direction of the limiting holes 41; when the second rod 3 rotates, it can apply a force to the transmission member 6 along the second axis, so that the transmission member 6 drives the second connecting portion 52 to move closer to or away from the first connecting portion 51 on the second axis. Such a setting can more conveniently adjust the inclination angle of the tabletop 200.

[0065] For example, after the tabletop 200 is unfolded, the tabletop 200 can be manually lifted upward. At this time, it can drive the first rod 2, the second rod 3, the adjusting member 4 and the transmission member 6 to rotate, and during this process, the second rod 3 can apply a force to the transmission member 6 to drive the second connecting portion 52 to approach the first connecting portion 51, thereby causing the second connecting portion 52 to withdraw from the limiting hole 41. At this time, manual force can be applied to make the second connecting portion 52 slide along the adjusting member 4; subsequently, when a downward force is applied to the tabletop 200, the first rod 2 and the second rod 3 can rotate until they abut. During this process, the second rod 3 applies a reverse force to the transmission member 6 along the second axis, so that the transmission member 6 drives the second connecting portion 52 to move away from the first connecting portion 51, thereby enabling the second connecting portion 52 to extend into another limiting hole 41; when the first rod 2 and the second rod 3 abut again, one adjustment of the angle of the tabletop 200 is completed. Additionally, in this embodiment, the first connecting portion 51 and the second connecting portion 52 can rotate around the second axis.

[0066] In one embodiment, the transmission member 6 is rotatably connected to the adjusting member 4; the axis about which the transmission member 6 rotates relative to the adjusting member 4 intersects the axis about which the adjusting member 4 rotates relative to the first rod 2 (i.e., the second axis); the second rod 3 can drive the transmission member 6 to rotate the transmission member 6 relative to the adjusting member 4, so as to realize the movement of the transmission member 6 (actually a part of the transmission member 6) relative to the adjusting member 4 in the extending direction of the second axis (i.e., the axial direction of the first connecting shaft 5), so that the second connecting portion 52 approaches or moves away from the first connecting portion 51 on the second axis.

[0067] Preferably, the axis around which the transmission member 6 rotates relative to the adjusting member 4 is perpendicular to the second axis.

[0068] In one embodiment, as Figure 5 shown, in the arrangement direction of each limiting hole 41, the transmission member 6 has a first connecting area, a second connecting area and a third connecting area which are arranged at intervals in sequence; the first connecting area is connected to the second connecting portion 52; the second connecting area is connected to the adjusting member 4; the second rod 3 can apply a force along the axis of the first connecting shaft 5 to the transmission member 6 in the third connecting area to rotate the transmission member 6 relative to the adjusting member 4. Wherein, after the transmission member 6 is connected to the adjusting member 4, a lever structure is formed, and the second rod 3 can apply a force to one end of the lever (i.e., the third connecting area) to drive the other end of the transmission member 6 (i.e., the first connecting area) to drive the second connecting portion 52 to approach or move away from the first connecting portion 51.

[0069] As Figure 2 、 Figure 5 and Figure 6 shown, in one embodiment, the second rod 3 and the adjusting member 4 are rotatably connected through the second connecting shaft 7, and the second rod 3 and the adjusting member 4 can rotate relative to each other about the axis of the second connecting shaft 7, wherein the axis of the second connecting shaft 7 is the fourth axis; the third connecting area is connected to the second connecting shaft 7; wherein, the transmission member 6 can rotate relative to the second connecting shaft 7 about the fourth axis and can move relative to the second rod 3 along the axial direction of the first connecting shaft 5; when the second rod 3 drives the second connecting shaft 7 to rotate relative to the transmission member 6, a force along the axis of the first connecting shaft 5 can be applied to the transmission member 6 through the second connecting shaft 7, so that the transmission member 6 drives the second connecting portion 52 to approach or move away from the first connecting portion 51.

[0070] Wherein, the second rod 3 and the second connecting shaft 7 cannot rotate relative to each other about the fourth axis. Among them, the second rod 3 and the second connecting shaft 7 can be fixedly connected. At this time, the two can be fixed together by means such as welding or threaded connection. Of course, the second rod 3 and the second connecting shaft 7 can also be made unable to rotate relative to each other about the fourth axis through corresponding limiting structures.

[0071] The adjusting member 4 is provided with a second connection hole 46, and the second connecting shaft 7 passes through the second connection hole 46, enabling the adjusting member 4 and the second connecting shaft 7 to rotate relative to each other about the fourth axis, thereby realizing the rotation of the adjusting member 4 and the second rod 3 about the fourth axis.

[0072] As Figure 6 shown, the transmission member 6 is provided with a third connection hole 61, and the second connecting shaft 7 passes through the third connection hole 61, enabling the transmission member 6 and the second connecting shaft 7 to rotate relative to each other about the fourth axis, thereby realizing the rotation of the transmission member 6 and the second rod 3 about the fourth axis.

[0073] As Figure 6 shown, in an embodiment, the second connecting shaft 7 is provided with a slot 71, and the transmission member 6 is provided with a block 62; the block 62 is located within the slot 71; when the second connecting shaft 7 rotates relative to the transmission member 6, the side wall of the slot 71 can apply a force to the block 62 along the axis of the first connecting shaft 5. Wherein, the side wall of the slot 71 refers to the groove wall of the slot 71 in the extending direction of the second axis.

[0074] The side wall of the slot 71 can be wavy. In the circumferential direction of the second connecting shaft 7, the distances between the regions of the side wall of the slot 71 and the second rod 3 on the first axis gradually change, such that when the second connecting shaft 7 rotates, it can drive the third connection region of the transmission member 6 to approach or move away from the second rod 3.

[0075] There are two side walls of the slot 71. When the second connecting shaft 7 rotates forward (at this time, the tabletop 200 is lifted upward), one side wall is used to push the third connection region away from the second rod 3, and when the second connecting shaft 7 rotates in the reverse direction, the other side wall is used to push the third connection region closer to the second rod 3. Additionally, the block 62 can be arranged within the third connection hole 61. Through the cooperation of the slot 71 and the block 62, it can also prevent the transmission member 6 from disengaging from the second connecting shaft 7.

[0076] It should be noted that when the second connecting shaft 7 rotates, the design of using the side wall of the slot 71 to push the block 62 located within the slot 71 to move linearly in a reciprocating manner can be an existing technology.
