[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1 , Figure 2 The figure shows a specific embodiment of the vehicle seat 10 of the present invention, wherein the vehicle seat 10 comprises a seat 11 and a backrest 12, wherein the rear side of the backrest 12 has a seat table 20 that can be extended or retracted, that is, the seat table 20 can be switched between a storage position and a working position for use by passengers in the rear seats.

[0038] Among them, Figure 3 As shown, a locking assembly 30 is also provided at the rear side of the backrest 12, and the locking assembly 30 includes a locking tongue 31 and a locking button 32 for controlling the extension and retraction of the locking tongue 31; when the locking tongue 31 is extended, it can be engaged with the seat table 20 to keep the seat table 20 in the storage position; when the locking button 32 is triggered, the locking tongue 31 is retracted, and the seat table 20 is in an unlocked state; the seat table 20 can be pivoted to the working position under the driving force of the user, so that the rear passengers can work on the move, place items, etc. Specifically, a clamping groove 21a is provided on the end surface of the table body 21 of the seat table 20, and when the table body 21 is in the storage position, the extended locking tongue 31 is clamped in the clamping groove 21a.

[0039] Specifically, Fig. 9 As shown, a first seat pivot portion 121 and a second seat pivot portion 122 are disposed inside the rear side surface of the backrest 12 , and the seat table 20 is pivotally connected to the first seat pivot portion 121 and the second seat pivot portion 122 .

[0040] like Figure 4 , Figure 5It is a specific embodiment of the chair table board 20 of the present invention, which includes a table board body 21, a first connecting rod 22 and a second connecting rod 23; wherein, the first side surface of the table board body 21 is provided with a first table board pivot portion 211 and a second table board pivot portion 212, and the first connecting rod 22 and the second connecting rod 23 pivotally connected to the table board body 21; one end of the first connecting rod 22 is pivotally connected to the first table board pivot portion 211, and the other end is pivotally connected to the first seat pivot portion 121 of the backrest 12; one end of the second connecting rod 23 is pivotally connected to the second table board pivot portion 212, and the other end is pivotally connected to the second seat pivot portion 122 of the backrest 12; Figure 4 , Figure 5 As shown, the first connecting rod 22 is provided with at least one flexible buffer portion 24, and when the table board body 21 is located at the storage position or the working position, the partial area of ​​the first connecting rod 22 having the flexible buffer portion 24 abuts against the second connecting rod 23. In other alternative embodiments, at least one flexible buffer portion 24 is provided on the second connecting rod 23, and when the table board body 21 is located at the storage position or the working position, the partial area of ​​the second connecting rod 23 having the flexible buffer portion 24 abuts against the first connecting rod 22; or, the first connecting rod 22 and the second connecting rod 23 respectively have flexible buffer portions 24, and when the table board body 21 is located at the storage position or the working position, the partial areas of the first connecting rod 22 and the second connecting rod 23 having the flexible buffer portions 24 are arranged relative to each other and abut against each other.

[0041] The seat table 20 is provided with a flexible buffer portion 24 on the first link 22 and / or the second link 23. When the table body 21 is in the storage position or the working position, the first link 22 and the second link 23 are arranged opposite to each other with the flexible buffer portion 24. When the vehicle is bumpy, a rigid collision between the first link 22 and the second link 23 can be avoided, thereby reducing abnormal noise of the seat table 20.

[0042] Specifically, the flexible buffer portion 24 is a gasket or a pad made of a flexible material. For example, the flexible buffer portion 24 is a rubber pad, and its molding structure can be determined according to its installation position. In an optional embodiment, the flexible buffer portion 24 is molded into a circular protrusion 233.

[0043] In order to enable the seat table board 20 to achieve flexible material contact in both the storage position and the working position, and avoid abnormal noise caused by rigid material contact; two flexible buffer parts 24 are set on the first connecting rod 22 and / or the second connecting rod 23, namely the first flexible buffer part 24a and the second flexible buffer part 24b. When the table board body 21 is in the storage position, the partial areas of the first connecting rod 22 and the second connecting rod 23 with the first flexible buffer part 24a arranged opposite to each other abut against each other to achieve flexible contact between the first connecting rod 22 and the second connecting rod 23; when the table board body 21 is in the working position, the partial areas of the first connecting rod 22 and the second connecting rod 23 with the second flexible buffer part 24b arranged opposite to each other abut against each other to achieve flexible contact between the first connecting rod 22 and the second connecting rod 23.

[0044] Specifically, the first seat pivot portion 121 and the second seat pivot portion 122 are arranged along the up-down direction of the rear side of the backrest 12, and specifically, the first seat pivot portion 121 is located at the lower side of the second seat pivot portion 122. Correspondingly, the first table board pivot portion 211 and the second table board pivot portion 212 are arranged along the up-down direction of the seat table board 20 in the storage state, wherein the first table board pivot portion 211 is close to the end of the table board body 21, and the second table board pivot portion 212 is located in the middle area of ​​the table board body 21; that is, when the seat table board 20 is in the storage position, the first table board pivot portion 211 is located at the lower side of the second table board pivot portion 212.

[0045] Specifically, Figure 6 As shown, a side surface of the table top body 21 is provided with a connecting rod installation groove 213, and the first table top pivot portion 211 and the second table top pivot portion 212 are respectively arranged on the groove wall of the connecting rod installation groove 213. Figure 4 , Figure 5 As shown, the first connecting rod 22 and the second connecting rod 23 are respectively connected to the first table board pivot part 211 and the second table board pivot part 212 through a pivot shaft. More specifically, in order to improve the support stability of the table board body 21, the table board body 21 is provided with two or more connecting rod installation grooves 213, and the table board body 21 can be supported by multiple sets of first connecting rods 22 and second connecting rods 23.

[0046] Specifically, in one embodiment, the flexible buffer portion 24 is provided on the first connecting rod 22, and the second connecting rod 23 is provided with a protrusion 233 at a corresponding position. When the table board body 21 is in the storage position or the working position, the flexible buffer portion 24 of the first connecting rod 22 abuts against the protrusion 233 of the second connecting rod 23. By providing the protrusion 233 structure, the contact area between the first connecting rod 22 and the second connecting rod 23 can be reduced, the contact is tight, and it is not easy to shake. More specifically, the protrusion 233 is integrally formed on the second connecting rod 23, and it is a rigid structure together with the second connecting rod 23.

[0047] The first connecting rod 22 is provided with a first flexible buffer portion 24a and a second flexible buffer portion 24b, the first flexible buffer portion 24a is close to the second seat pivot portion 122, and the second flexible buffer portion 24b is close to the first seat pivot portion 121; the second connecting rod 23 is correspondingly provided with a first protrusion 233a and a second protrusion 233b; when the table board body 21 is located in the storage position, the first protrusion 233a abuts against the first flexible buffer portion 24a; when the table board body 21 is located in the working position, the second protrusion 233b abuts against the second flexible buffer portion 24b.

[0048] By placing a flexible buffer portion 24 (including a first flexible buffer portion 24a and a second flexible buffer portion 24b) on the first link 22 and a rigid protrusion 233 (including a first protrusion 233a and a second protrusion 233b) on the second link 23, when the seat table 20 is pivoted to the working position, the rigid second protrusion 233b on the second link 23 located on the upper side acts on the rubber pad (i.e., the second flexible buffer portion 24b) of the first link 22 located on the lower side, thereby preventing the rubber pad from being located on the second link 23, and the second protrusion 233b from contacting the rubber pad, causing the second link 23 to bounce upward, resulting in the upward tilting of the table body 21. At the same time, the first flexible buffer portion 24a is adjacent to the second seat pivot portion 122, and when the seat table 20 is pivoted to the working position, the first flexible buffer portion 24a is located inside the rear side of the backrest 12, thereby avoiding the problem of being located outside the opening of the backrest 12 and affecting the overall effect of the table body 21.

[0049] like Figure 7As shown, the first connecting rod 22 includes a secondary rod 222 located at the main rod 221 and close to the first table board pivoting portion 211. The secondary rod 222 and the main rod 221 have different extension directions, and the angle between the two is an obtuse angle. The first flexible buffer portion 24a is arranged on the secondary rod 222. When the table board body 21 is in the working position, the secondary rod 222 extends in the horizontal direction, and the main rod 221 is inclined relative to the horizontal direction and inclined upward from the backrest 12 to the table board. Since the secondary rod 222 extends in the horizontal direction when the table board body 21 is in the working position, it can be located inside the connecting rod mounting groove 213 of the table board body 21, avoiding the problem that the second connecting rod 23 is located outside the table board body 21, resulting in a reduced bearing area of ​​the table board body 21.

[0050] During the process of the table board body 21 moving from the working position to the storage position, the main rod body 221 and the auxiliary rod body 222 flip downward around the pivot axis of the first seat pivot part 121, so that the main rod body 221 is finally tilted relative to the vertical direction and tilted downward from the backrest 12 to the table board, and the auxiliary rod body 222 extends along the vertical direction, and the first flexible buffer part 24a abuts against one side surface of the table board body 21; flexible contact between the first connecting rod 22 and the table board body 21 is achieved to avoid abnormal noise at this position caused by vehicle shaking.

[0051] Specifically, in an optional implementation manner, Figure 8 As shown, the second connecting rod 23 is integrally formed as a V-shaped bending rod, which includes a first rod body 231 and a second rod body 232. The first rod body 231 and the second rod body 232 extend in different directions and form a bend with an obtuse angle. The end of the first rod body 231 is pivotally connected to the second table board pivoting portion 212, and the end of the second rod body 232 is pivotally connected to the second seat pivoting portion 122. The first protrusion 233a is arranged on the first rod body 231. When the table board body 21 is in the working position, the first rod body 231 extends in the horizontal direction, and the first protrusion 233a located on the first rod body 231 can act on the first flexible buffer portion 24a of the first connecting rod 22 located at the lower side thereof to achieve smooth contact. More specifically, the first protrusion 233a is located on a partial area close to the second rod body 232.

[0052] Specifically, the second protrusion 233b is also provided on the first rod 231, and the distance between the second protrusion 233b and the first table board pivot portion 211 is smaller than the distance between the first protrusion 233a and the first table board pivot portion 211. When the table board body 21 moves from the working position to the storage position, the second rod 232 and the first rod 231 flip downward around the pivot axis of the second seat pivot portion 122, and the extension direction of the first rod 231 is inclined to the vertical direction, and a part of the first rod 231 is opposite to the main rod 221 of the first connecting rod 22, and the second protrusion 233b abuts against the first flexible buffer portion 24a to achieve flexible contact.

[0053] Specifically, Fig. 9 As shown, in an optional embodiment, a first elastic member 41 is arranged between the first seat pivot portion 121 and the first connecting rod 22, and a second elastic member 42 is arranged between the second seat pivot portion 122 and the second connecting rod 23, and the elastic forces of the first elastic member 41 and the second elastic member 42 act on the first connecting rod 22 and the second connecting rod 23 respectively; after the seat table 20 is in the unlocked state, the elastic forces of the first elastic member 41 and the second elastic member 42 cause the seat table 20 to flip to the first position (such as the first position) in the direction away from the backrest 12. Figure 2 As shown), the angle between the extension direction of the table top body 21 in the first position and the rear side surface of the backrest 12 is less than 45°.

[0054] More specifically, the first elastic member 41 is a first torsion spring mounted on the pivot shaft of the first seat pivot portion 121, and the second elastic member 42 is a second torsion spring mounted on the pivot shaft of the second seat pivot portion 122; through the arrangement of the first elastic member 41 and the second elastic member 42, the seat table 20 can have a certain buffer during the flipping process from the storage position to the working position, and will not flip directly to the working position, thereby avoiding the problem of excessive vibration during the flipping process of the seat table 20 resulting in a shorter service life.

[0055] The present invention also provides a specific embodiment of a vehicle, which includes the seat table 20 described above, or the vehicle seat 10 described above, which will not be described in detail here. When the vehicle having the seat table 20 and the vehicle seat 10 is bumped during driving, the seat table 20 will not produce abnormal noise.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
