[0063] Further, see Attachment Figure 7 As shown in the attached reference Figure 3 and attached Figure 4 The first elastic member 23 includes a first rod 231, a second rod 232, a first fixed axis 233 and a second fixed axis 234. The first rod 231 and the second rod 232 are arranged in the width direction of the table top assembly 10, and the first rod 231 and the second rod 232 are arranged in the length direction (refer to the attached Figure 7 The first rod 231 and the second rod 232 are connected at one end thereof (in the direction d shown in the figure), the first rod 231 and the second rod 232 form an angle with each other, the first fixed shaft 233 is connected to the end of the first rod 231 which is away from the second rod 232, the second fixed shaft 234 is connected to the end of the second rod 232 which is away from the first rod 231, the first fixed shaft 233 extends toward the pawl 22 and is penetrated in the first fixing hole 222, and the second fixed shaft 234 extends toward the slider 21 and is penetrated in the second fixing hole 212.

[0064] It should be noted that, as shown in the reference appendix Figure 4 When the first fixed shaft 233 is located on the side of the connecting line a away from the tooth groove 31, the first elastic member 23 drives the pawl 22 to rotate towards the tooth groove 31 for cooperation with the tooth groove 31; when the first fixed shaft 233 is located on the side of the connecting line a towards the tooth groove 31, the first elastic member 23 drives the pawl 22 to rotate in the direction away from the tooth groove 31 so that the pawl 22 is disengaged from the tooth groove 31.

[0065] It can be understood that when the table board assembly 10 is opened from the storage state to the lowered use state, and a user places an item on the table board assembly 10, the table board assembly 10 is subjected to a downward pressure load, and the slider 21 has a tendency to move closer to the second rotating shaft 421. At this time, the first fixed shaft 233 is located on the side of the connecting line a away from the tooth groove 31, and the first elastic member 23 drives the pawl 22 to continue rotating towards the tooth groove 31 (in the counterclockwise direction as shown Figure 4 ), so that the pawl 22 is clamped with the tooth groove 31, ensuring that the adjustable-angle small table board 100 is in the bearing state.

[0066] When the user applies an upward lifting force to one end of the table board assembly 10 away from the back of the seat 200, the slider 21 moves in the direction away from the second rotating shaft 421, and the pawl 22 is forced to rotate to disengage from the tooth groove 31 (in the clockwise direction as shown Figure 4 ). After the slider 21 slides a certain distance such that the pawl 22 moves to face another tooth groove 31, at this time, the first fixed shaft 233 is located on the side of the connecting line a away from the tooth groove 31, and the first elastic member 23 drives the pawl 22 to continue rotating towards the tooth groove 31 (in the counterclockwise direction as shown Figure 4 ), so that the pawl 22 is clamped with the tooth groove 31 again. Through the above lifting movement, the pawl 22 can be successively moved to the one of the multiple tooth grooves 31 that is farthest from the second rotating shaft 421. At this time, the adjustable-angle small table board 100 is in the uppermost use position. Once past the uppermost use position, if the user continues to apply an upward lifting force to one end of the table board assembly 10 away from the back of the seat 200, it can be manually operated to determine whether the adjustable-angle small table board 100 enters the lowered use state or the storage state.

[0067] When the table board assembly 10 enters the storage state from the uppermost use position, the pawl 22 has been clamped and engaged with the tooth groove 31 that is farthest from the second rotating shaft 421 among the multiple tooth grooves 31. When the user continues to apply an upward lifting force to one end of the table board assembly 10 away from the back of the seat 200, the pawl 22 is forced to rotate to disengage from the tooth groove 31 (in the clockwise direction as shown Figure 4In the clockwise direction shown, when the pawl 22 rotates to a position where the first fixed shaft 233 is on the side facing the tooth groove 31 of the connecting line a, the first elastic member 23 drives the pawl 22 to rotate in a direction away from the tooth groove 31 so that the pawl 22 is disengaged from the tooth groove 31, preventing the pawl 22 from engaging with the tooth groove 31 again, and ensuring the normal storage of the adjustable-angle small table board 100.

[0068] Preferably, the slider 21 is a die-cast part, which can ensure the strength, precision and surface finish of the slider 21. The slider 21 and the pawl 22 are fastened by riveting or screwing, and the rotational freedom of the pawl 22 relative to the slider 21 is retained. The connection is reliable, the process is simple, and the operation is convenient, reducing the production cost of the adjustable-angle small table board 100.

[0069] In a further embodiment of the present invention, refer to the attached Figure 2 and the attached Figure 3 and the attached Figure 4 and the attached Figure 8 As shown, the first connecting rod 41 is located below the second connecting rod 42. When the table board body 1 is at the maximum lifting and fixing angle, the pawl 22 cooperates with the tooth groove 31 farthest from the second rotation shaft 421. The distance between the ends of the first connecting rod 41 and the second connecting rod 42 away from the seat 200 is the largest. At this time, it is the uppermost use position of the adjustable-angle small table board 100. If the user continues to apply an upward lifting force to the end of the table board assembly 10 away from the back of the seat 200, the user can manually operate to determine whether the adjustable-angle small table board 100 enters the lowered use state or the storage state to meet the user's next needs.

[0070] Furthermore, when the table board body 1 is in the storage state, the table board body 1 fits against the back of the seat 200, which can minimize the presence of the table board assembly 10 in the storage state, reduce the occupied space of the adjustable-angle small table board 100 in the vehicle, and avoid affecting the normal activities of the user when the user does not use the adjustable-angle small table board 100, improving the user's comfort.

[0071] Even further, refer to the attached Figure 4 As shown, within at least a partial angular range during the process of the table board body 1 rotating from the maximum lifting and fixing angle to the storage state, the first elastic member 23 can drive the pawl 22 to rotate in a direction away from the tooth groove 31 and disengage from the tooth groove 31, preventing the pawl 22 from engaging with the tooth groove 31 again during the storage process and avoiding affecting the normal storage of the adjustable-angle small table board 100.

[0072] In a further embodiment of the present invention, refer to the attached Figure 4 and the attached Figure 5 and the attached Figure 6As shown, the pawl 22 has a protrusion 221. A stop post 211 is provided on one side of the slider 21 facing the pawl 22. When the pawl 22 is disengaged from the tooth groove 31, the protrusion 221 and the stop post 211 can abut against each other to limit the rotation of the pawl 22 in the direction away from the tooth groove 31. The arrangement of the stop post 211 and the protrusion 221 can play a limiting role to prevent the first elastic member 23 from being disengaged from the pawl 22 and / or the slider 21 due to an excessive relative rotation angle between the pawl 22 and the slider 21, ensuring the effectiveness of the first elastic member 23 and extending the service life of the adjustable-angle table board 100.

[0073] In a further embodiment of the present invention, with reference to the attached Figure 2 drawing, Figure 4 drawing, Figure 8 and the attached

[0074] shown, when the table board body 1 is in the storage state, the first elastic member 23 drives the pawl 22 to rotate towards the tooth groove 31 and cooperate with the tooth groove 31 closest to the second rotation shaft 421, which can ensure the normal storage of the table board assembly 10, prevent the table board body 1 from disengaging from the storage state when the user does not use the adjustable-angle table board 100, thereby ensuring the reliability of the adjustable-angle table board 100, extending the service life of the adjustable-angle table board 100, and improving the user experience.

[0074] In a specific example, with reference to the attached Figure 2 drawing Figure 3 and the attached

[0075] shown, the table board body 1 has a mating plate 13. A mating groove 131 is provided on the mating plate 13. The mating groove 131 is disposed opposite to the sliding groove 123. A plurality of tooth grooves 31 are provided on the bottom wall of the mating groove 131. When the table board assembly 10 is adjusted from the state of being put down for use to the storage state, the pawl 22 gradually moves in the direction away from the second rotation shaft 421. When the protrusion 221 of the pawl 22 contacts the inner wall of the mating groove 131 on the side away from the second rotation shaft 421, the pawl 22 rotates and is released from the tooth groove 31. The pawl 22 rotates in the direction away from the tooth groove 31 under the action of the first elastic member 23 until it abuts against the stop post 211. When the table board assembly 10 is in the storage state, the first elastic member 23 drives the pawl 22 to rotate towards the tooth groove 31 and cooperate with the tooth groove 31 closest to the second rotation shaft 421. At this time, the pawl 22 is in contact with the inner wall of the mating groove 131 on the side close to the second rotation shaft 421.

[0075] In a further embodiment of the present invention, with reference to the attached Figure 8As shown, a second elastic member 201 is provided on the back of the seat 200, which is used to drive the second link 42 to move in a direction away from the seat 200. When the user needs to use the adjustable-angle small table board 100, it can drive the table board assembly 10 to separate the table board assembly 10 from the back of the seat 200, facilitating the user to open the table board assembly 10 by hand, reducing the difficulty of using the adjustable-angle small table board 100, and improving the user experience.

[0076] In a further embodiment of the present invention, referring to the attached Figure 8 As shown, within at least a partial angle range from the maximum lifting and fixing angle to the storage state of the table board body 1, the second link 42 abuts against the second elastic member 201 to prevent the second link 42 from moving towards the back of the seat 200. When the table board body 1 is in the lowered and in-use state, the second link 42 is spaced from the second elastic member 201 to prevent the second elastic member 201 from driving the second link 42, thereby ensuring the stability of the table board body 1 and preventing the table board body 1 from shaking during use.

[0077] It can be understood that when the table board assembly 10 enters the storage state from the uppermost in-use position, the pawl 22 just starts to be tightly engaged with the tooth groove 31 that is farthest from the second rotation axis 421 among the multiple tooth grooves 31. When the user continues to apply an upward lifting force to the end of the table board assembly 10 away from the back of the seat 200, the pawl 22 rotates under the force to release the engagement with the tooth groove 31 (in the clockwise direction as shown in Figure 4 As shown). When the first fixed shaft 233 of the pawl 22 rotates to the side of the connecting line a facing the tooth groove 31, the first elastic member 23 drives the pawl 22 to rotate in a direction away from the tooth groove 31 until the protruding portion 221 abuts against the stop post 211, so that the pawl 22 is disengaged from the tooth groove 31. When the second link 42 abuts against the second elastic member 201, the second elastic member 201 restricts the continuous rotation of the second link 42. At this time, the table board assembly 10 can only rotate around the second rotation axis 421. The end of the first link 41 away from the back of the seat 200 can only be forced to move along the length direction of the sliding groove 123 towards the second rotation axis 421 until the pawl 22 moves to the tooth groove 31 closest to the second rotation axis 421 and engages with it. The first link 41 cannot move further. When the user continues to lift the table board assembly 10, only the second link 42 can compress the second elastic member 201 to move towards the back of the seat 200 until the table board body 1 fits against the back of the seat 200.

[0078] In some embodiments of the present invention, referring to the attached Figure 1 and the attached Figure 2 As shown, the link assembly 20 is along the length direction of the table board assembly 10 (referring to the attached Figure 2The connecting rod assembly 20 may be arranged in a plurality of intervals along the length direction of the table top assembly 10 (in the left and right directions shown in the figure), thereby improving the driving effect of the connecting rod assembly 20 on the table top assembly 10, ensuring the adjustable angle of the small table top 100, improving the practicality of the small table top 100, bringing convenience and comfort to the user, and improving the user's experience. For example, the connecting rod assembly 20 may be two, three, or four arranged in intervals along the length direction of the table top assembly 10. In a specific example, refer to the attached Figure 1 and attached Figure 2 As shown, there are two connecting rod assemblies 20 spaced apart along the length direction of the table top assembly 10. The two connecting rod assemblies 20 are respectively located at the two ends of the length direction of the table top assembly 10, which can ensure the driving effect of the table top assembly 10 from two places, ensure the adjustable angle of the small table top 100, ensure the reliability and stability of the small table top 100, and ensure the user experience.

[0079] The present invention also provides a seat assembly 1000 having the adjustable angle small table 100 of the above embodiment.

[0080] like Figure 8 As shown, the seat assembly 1000 according to the embodiment of the present invention includes a seat 200 and the above-mentioned adjustable angle small table 100.

[0081] Specifically, refer to the attached Figure 8 As shown, the adjustable angle small table 100 is arranged at the rear side of the seat 200, and a mounting bracket 202 is arranged on the back of the seat 200, and the mounting bracket 202 extends in the up-down direction, and the first connecting rod 41 and the second connecting rod 42 are rotatably connected to the back of the seat 200 at one end away from the table assembly 10, and the first connecting rod 41 and the second connecting rod 42 are respectively connected to the mounting bracket 202 in the length direction (refer to the attached Figure 8 The ends of the first connecting rod 41 and the second connecting rod 42 (in the up and down direction as shown) are spaced apart in the up and down direction at one end of the first connecting rod 41 and the second connecting rod 42 facing away from the table top assembly 10, thereby ensuring the normal rotation of the first connecting rod 41 and the second connecting rod 42 and ensuring the normal movement of the connecting rod assembly 20.

[0082] It should be noted that the mounting bracket 202 is detachably connected to the seat 200. By fixing the mounting bracket 202 on different seats 200, the adjustable angle small table 100 can be matched with different seats 200, thereby improving the compatibility and adaptability of the adjustable angle small table 100, reducing the development cost of the seat assembly 1000, and shortening the development time of the seat assembly 1000.

[0083] It should be noted that the length direction of the first connecting rod 41 (see Appendix Figure 2The two ends of the second connecting rod 42 are connected to the mounting bracket 202 and the slider 21 by bolts and retain the rotational freedom. Figure 2 The two ends (in the f direction shown) are connected to the mounting bracket 202 and the longitudinal beam 122 respectively by bolts and retain the rotational freedom.

[0084] Furthermore, the back of the seat 200 has a first connecting portion. When the table assembly 10 is stored in a storage state that fits the back of the seat 200, the first connecting portion is used to snap into place with the table assembly 10. When the user does not need to use the adjustable angle small table 100, the adjustable angle small table 100 can be fixed to the back of the seat 200, thereby preventing the adjustable angle small table 100 from being opened and occupying the user's activity space, thereby preventing the user from getting on and off the vehicle normally.

[0085] In a specific example, see the attached Figure 1 As shown, the decorative strip 113 of the table top assembly 10 has a second connecting portion 114, the second connecting portion 114 is formed as a slot, and the first connecting portion is formed as a hook. When the table top assembly 10 is stored to a storage state in close contact with the back of the seat 200, the hook and the slot are engaged with each other, which can facilitate the fixation and cancellation of the table top assembly 10 and the back of the seat 200, thereby ensuring the reliability of the connection between the table top assembly 10 and the back of the seat 200 in the storage state and preventing the table top assembly 10 from opening suddenly when not in use.

[0086] It can be understood that, in the process of the table top assembly 10 entering the storage state from the most used position, when the second connecting rod 42 abuts against the second elastic member 201, the second elastic member 201 restricts the second connecting rod 42 from continuing to rotate. At this time, the table top assembly 10 can only rotate with the second rotating shaft 421 as the rotation center, and the end of the first connecting rod 41 away from the back of the seat 200 can only be forced to move toward the second rotating shaft 421 along the length direction of the slide groove 123 until the pawl 22 moves to the tooth groove 31 closest to the second rotating shaft 421 and cooperates with it. The first connecting rod 41 cannot continue to move, and the user continues to lift the table top assembly 10, which can only cause the second connecting rod 42 to press the second elastic member 201 toward the seat. The first connection part 114 cooperates with the second connection part 114 to fix the table board body 1 on the back of the seat 200, thereby completing the storage of the adjustable angle small table board 100; when the user needs to use the adjustable angle small table board 100, the user first manually releases the cooperation between the first connection part 114 and the second connection part 114. Since the second elastic member 201 always has an elastic force acting on the second connecting rod 42 in the stored state, the second elastic member 201 drives the second connecting rod 42 to rotate at this time, so as to separate the table board body 1 from the back of the seat 200, so that the user can put his hand into the gap between the table board body 1 and the back of the seat 200 to put down the table board body 1.

[0087] According to the seat assembly 1000 of the embodiment of the present utility model, by providing the adjustable-angle small table board 100 as described above, the link assembly 20 includes a first link 41 and a second link 42. One end of the first link 41 and one end of the second link 42 are adapted to be rotatably connected to the back of the seat 200 and are spaced apart in the up-and-down direction. The other end of the first link 41 is rotatably connected to the table board assembly 10 through a first rotating shaft 411, and the other end of the second link 42 is rotatably connected to the table board assembly 10 through a second rotating shaft 421. Along the width direction of the table board assembly 10, the first rotating shaft 411 and the second rotating shaft 421 are spaced apart and the distance therebetween is adjustable, so that the table board assembly 10 can rotate relative to the seat 200 through the link assembly 20, realizing the unfolding, folding and angle adjustment of the adjustable-angle small table board 100, enabling the user to freely adjust the angle of the table board assembly 10, no longer being limited by the use angle of the backrest of the front-row seat 200, which can improve the practicability of the adjustable-angle small table board 100, bring convenience and comfort to the user, and improve the user experience.

[0088] The present utility model also proposes a vehicle having the seat assembly 1000 of the above embodiment.

[0089] Specifically, the vehicle includes multiple rows of seats 200, and the multiple rows of seats 200 are spaced apart in the front-back direction (as Figure 8 shown). Among them, the backrest of the seat 200 located on the front side is provided with an adjustable-angle small table board 100. When the passengers in the back row need to place items, the adjustable-angle small table board 100 on the backrest of the front-row seat 200 can be opened, and the items can be placed on the table board body 1. When the passengers in the back row have no need to place items, the adjustable-angle small table board 100 on the backrest of the front-row seat 200 can be retracted to a retracted state that fits the backrest of the front-row seat 200, avoiding occupying the user's activity space and affecting the normal getting on and off of the user.

[0090] A vehicle according to an embodiment of the present utility model is provided with the above-mentioned seat assembly 1000. The link assembly 20 includes a first link 41 and a second link 42. One end of the first link 41 and one end of the second link 42 are adapted to be rotatably connected to the backrest of the seat 200 and are spaced apart in the up and down direction. The other end of the first link 41 is rotatably connected to the table assembly 10 through a first rotating shaft 411, and the other end of the second link 42 is rotatably connected to the table assembly 10 through a second rotating shaft 421. Along the width direction of the table assembly 10, the first rotating shaft 411 and the second rotating shaft 421 are spaced apart and the distance therebetween is adjustable, so that the table assembly 10 can rotate relative to the seat 200 through the link assembly 20, realizing the deployment, folding and angle adjustment of the adjustable-angle small table 100, enabling the user to freely adjust the angle of the table assembly 10, no longer being limited by the use angle of the backrest of the front row seat 200, which can improve the practicability of the adjustable-angle small table 100, bring convenience and comfort to the user, and improve the user experience.
