[0048] It should be noted that the reference Figure 2 As shown, the first rotating shaft 411 is fixed at one end of the first connecting rod 41 , and the first rotating shaft 411 is rotatably connected to the table top assembly 10 . The second rotating shaft 421 is fixed at one end of the second connecting rod, and the second rotating shaft 421 is rotatably connected to the table top assembly 10 .

[0049] Specifically, refer to the attached Figure 8 As shown, one end of the first link 41 and one end of the second link 42 may be directly rotatably connected to the back of the seat 200, or a mounting bracket 202 may be provided on the back of the seat 200, and the ends of the first link 41 and the second link 42 facing away from the table assembly 10 are respectively connected to the mounting bracket 202 in the length direction (see 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.

[0050] It can be understood that compared with the small table in the prior art that cannot adjust the angle, the present invention can ensure that when using the adjustable angle small table 100, the user can adjust the table assembly 10 to a roughly horizontal state and is no longer limited by the use angle of the backrest of the front seat 200. This can improve the practicality of the adjustable angle small table 100, bring convenience and comfort to the user, and improve the user's experience.

[0051] According to the adjustable angle small table 100 of the embodiment of the present invention, the connecting rod assembly 20 includes a first connecting rod 41 and a second connecting rod 42, one end of the first connecting rod 41 and one end of the second connecting rod 42 are suitable for rotationally connecting to the back of the seat 200 and are spaced apart in the up and down directions, the other end of the first connecting rod 41 is rotationally connected to the table board assembly 10 through a first rotating shaft 411, and the other end of the second connecting rod 42 is rotationally 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 is adjustable, so that the table board assembly 10 can be rotated relative to the seat 200 through the connecting rod assembly 20, so as to realize the unfolding, folding and angle adjustment of the adjustable angle small table 100, so that the user can freely adjust the angle of the table board assembly 10, and is no longer limited to the use angle of the backrest of the front seat 200, so as to improve the practicality of the adjustable angle small table 100, bring convenience and comfort to the user, and improve the user experience.

[0052] In some embodiments of the present invention, Figure 2 and attached Figure 3 As shown, the table top assembly 10 includes a table top body 1, an adjustment mechanism 2 and a locking mechanism 3. The table top body 1 has a width direction (refer to the attached Figure 2 The end of the second connecting rod 42 away from the seat 200 is rotatably connected to the table board body 1 through the second rotating shaft 421, and the adjustment mechanism 2 is arranged along the length direction of the sliding groove 123 (refer to the attached Figure 3 The position of the first connecting rod 41 (in the direction b shown in the figure) is adjustable, and one end of the first connecting rod 41 away from the seat 200 is rotatably connected to the adjustment mechanism 2 via the first rotating shaft 411.

[0053] It can be understood that in the width direction of the table board body 1, the second rotating shaft 421 can only rotate in place relative to the table board body 1, and will not move along the length direction of the slide groove 123, and the end of the first connecting rod 41 away from the seat 200 is fixed to the adjustment mechanism 2, and the adjustment mechanism 2 is adjustable in the length direction of the slide groove 123, so that the first rotating shaft 411 can be moved along the width direction of the table board body 1, thereby being able to change the angle between the first connecting rod 41, the second connecting rod 42 and the table board assembly 10, so that the user can freely adjust the angle of the table board assembly 10, so that when using the adjustable angle small table board 100, the user can adjust the table board assembly 10 to a roughly horizontal state, and is no longer limited by the use angle of the backrest of the front seat 200, which can improve the practicality of the adjustable angle small table board 100, bring convenience and comfort to the user, and improve the user's experience.

[0054] Further, see Attachment Figure 2 and attached Figure 3As shown, the locking mechanism 3 is arranged on the table top body 1, and is used to limit the adjustment mechanism 2 from moving toward the second rotating axis 421. When the user uses the adjustable angle small table top 100, the existence of the locking mechanism 3 can make the adjustment mechanism 2 only move in the direction away from the second rotating axis 421, but not move toward the second rotating axis 421. This can prevent the table top body 1 from flipping over due to the placement of objects, thereby improving the reliability of the adjustable angle small table top 100 and ensuring the user experience.

[0055] Preferably, the slide groove 123 is coated with plastic, which can eliminate the gap between the adjustment mechanism 2 and the slide groove 123 and ensure the sliding effect of the adjustment mechanism 2.

[0056] Further, in conjunction with the reference Figure 1 and attached Figure 2 As shown, the table top body 1 includes a shell 11 and a skeleton body 12. The shell 11 has an installation cavity and an avoidance groove 115. The avoidance groove 115 extends along the width direction of the table top assembly 10 to avoid the connecting rod assembly 20 and ensure the normal rotation of the first connecting rod 41 and the second connecting rod 42. The skeleton body 12 is arranged in the installation cavity, and the slide groove 123 is arranged on the skeleton body 12. The shell 11 can protect the skeleton body 12 and form a flat placement surface for users to place items, thereby improving the user experience.

[0057] Further, see Appendix Figure 1 As shown, the housing 11 includes a first cover plate 111, a second cover plate 112 and a decorative strip 113. The first cover plate 111 and the second cover plate 112 are arranged in a thickness direction of the table top assembly 10 (see attached Figure 1 The first cover plate 111 is connected to the skeleton body 12 by bolts, the second cover plate 112 is connected to the first cover plate 111 by snap-fitting, the first cover plate 111 and the second cover plate 112 jointly define an installation cavity and an avoidance groove 115, and the decorative strip 113 is covered by hot-melt riveting or snap-fitting means on the end of the first cover plate 111 and / or the second cover plate 112 facing away from the back of the seat 200, which can make up for the defects that may exist at the connection between the first cover plate 111 and the second cover plate 112, avoid the user from accidentally touching it and causing injuries, and can also play a decorative role on the adjustable angle small table 100, thereby improving the aesthetics of the adjustable angle small table 100.

[0058] Further, see the attached Figure 2 As shown, the skeleton body 12 includes a plurality of cross beams 121 and a plurality of longitudinal beams 122. The plurality of cross beams 121 are arranged along the length direction of the table top body 1 (see FIG. Figure 2The longitudinal beams 122 extend in the width direction of the table top body 1 and are spaced apart in the length direction of the table top body 1. The longitudinal beams 122 extend in the width direction of the table top body 1 and are spaced apart in the length direction of the table top body 1. Figure 2 Both ends of the adjustable angle table 100 (in the direction b shown) are connected to multiple cross beams 121, and the slide groove 123 is arranged at one end of the length direction of part of the longitudinal beam 122, thereby ensuring the structural strength and reliability of the skeleton body 12, and preventing the user from placing too many items or the items are too heavy, which may cause the adjustable angle table 100 to fail.

[0059] In a specific example, see the attached Figure 2 As shown, the skeleton body 12 includes two cross beams 121 and four longitudinal beams 122. The two cross beams 121 are respectively located at the two ends of the width direction of the table board body 1, and the two ends of the length direction of the four longitudinal beams 122 are respectively connected to the two cross beams 121. The four longitudinal beams 122 are in the length direction of the table board body 1 (refer to the attached Figure 2 The two longitudinal beams 122 at both ends of the table top body 1 in the length direction are evenly spaced apart, wherein a slide groove 123 is provided at the same end.

[0060] It should be noted that the reference Figure 2 As shown, a damper 124 is provided on the adjustable angle small table 100, and the two ends of the damper 124 are respectively connected to the skeleton body 12 and the second connecting rod 42, which can generate damping force during the rotation of the adjustable angle small table 100, absorb the impact force in the mechanical movement, reduce mechanical vibration, play a buffering role, protect the adjustable angle small table 100, extend the service life of the adjustable angle small table 100, adjust the operating feel of the adjustable angle small table 100, and improve the user experience.

[0061] In a further embodiment of the present invention, referring to the attached Figure 3 and attached Figure 4As shown, the locking mechanism 3 is formed as a plurality of tooth grooves 31 provided on the table top body 1, and the plurality of tooth grooves 31 are arranged at intervals along the length direction of the slide groove 123. The adjustment mechanism 2 includes a slider 21, a pawl 22 and a first elastic member 23. The slider 21 is movably provided in the slide groove 123, the first connecting rod 41 is rotatably connected to the slider 21, one end of the pawl 22 is rotatably connected to the slider 21, and the other end of the pawl 22 cooperates with the tooth groove 31. The slider 21 is movable along the length direction of the slide groove 123, and the pawl 22 can be driven by the slider 21 to move along the length direction of the slide groove 123 to realize the pawl 22 cooperates with different tooth grooves 31, and the first elastic member 23 is connected to the pawl 22 and the slider 21. When the table top assembly 10 is put down for use, the first elastic member 23 is used to drive the pawl 22 to rotate toward the tooth groove 31 and cooperate with the tooth groove 31. When the user adjusts the angle of the table top assembly 10, the first elastic member 23 can automatically drive the pawl 22 to rotate toward the tooth groove 31, thereby ensuring the cooperation between the locking mechanism 3 and the adjustment mechanism 2, preventing the table top body 1 from flipping over due to the placement of objects, improving the reliability of the adjustable angle small table top 100, reducing the user's operating difficulty, and ensuring the user's usage experience.

[0062] Specifically, refer to the attached Figure 3 and attached Figure 4 As shown in the attached reference Figure 5 and attached Figure 6 The pawl 22 is provided with a rotating hole 223 and a first fixed hole 222, the slider 21 is provided with a third rotating shaft 213 and a second fixed hole 212, the third rotating shaft 213 is provided on the side of the slider 21 facing the pawl 22, the third rotating shaft 213 is passed through the rotating hole 223 to make the pawl 22 and the slider 21 rotatably connected, the first fixed hole 222 and the second fixed hole 212 are spaced apart in the width direction of the table top assembly 10, and the connecting line between the axis of the second fixed hole 212 and the axis of the third rotating shaft 213 is a.

[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 the reference Figure 4 As shown, when the first fixed shaft 233 is located on the side of the line a facing away from the tooth groove 31, the first elastic member 23 drives the pawl 22 to rotate toward the tooth groove 31 to cooperate with the tooth groove 31; when the first fixed shaft 233 is located on the side of the line a facing the tooth groove 31, the first elastic member 23 drives the pawl 22 to rotate in the direction away from the tooth groove 31 to disengage the pawl 22 from the tooth groove 31.

[0065] It can be understood that when the table top assembly 10 is opened from the storage state to the lowered use state, the user places an item on the table top assembly 10, the table top assembly 10 is subjected to a downward pressure load, and the slider 21 has a movement tendency to approach the second rotation axis 421. At this time, the first fixed axis 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 to rotate toward the tooth groove 31 (such as Figure 4 The pawl 22 is rotated in a counterclockwise direction as shown in the figure, so that the pawl 22 is clamped with the tooth groove 31, thereby ensuring that the adjustable angle small table 100 is in a load-bearing state.

[0066] When the user applies an upward force to the end of the table assembly 10 away from the back of the seat 200, the slider 21 moves in a direction away from the second rotation axis 421, and the pawl 22 is rotated by the force to release the engagement with the tooth groove 31 (such as Figure 4 When the slider 21 slides a certain distance so that the pawl 22 moves to face the other tooth groove 31, 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 to rotate toward the tooth groove 31 (as shown in the clockwise direction). Figure 4 The pawl 22 is moved in the counterclockwise direction as shown in the figure, so that the pawl 22 is clamped with the tooth groove 31 again. The pawl 22 can be moved one by one to the one of the multiple tooth grooves 31 that is farthest from the second rotation axis 421 through the lifting movement. At this time, the adjustable angle small table 100 is in the most used position. Once the most used position is exceeded, if the user continues to apply an upward lifting force to the end of the table assembly 10 that is away from the back of the seat 200, the user can manually determine whether the adjustable angle small table 100 enters the lowered use state or the storage state.

[0067] When the table top assembly 10 enters the storage state from the most used position, the pawl 22 has been tightly engaged with the tooth groove 31 farthest from the second rotation axis 421 among the multiple tooth grooves 31. The user continues to apply an upward force to the end of the table top assembly 10 away from the back of the seat 200, and the pawl 22 is rotated by the force to release the engagement with the tooth groove 31 (such as Figure 4When the pawl 22 rotates to the side of the first fixed axis 233 located on the line a facing the tooth groove 31, the first elastic member 23 drives the pawl 22 to rotate in the direction away from the tooth groove 31 to disengage the pawl 22 from the tooth groove 31, thereby preventing the pawl 22 from engaging with the tooth groove 31 again, thereby ensuring the normal storage of the adjustable angle table 100.

[0068] Preferably, the slider 21 is a die-casting, which can ensure the strength, precision and 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, the operation is convenient, and the production cost of the adjustable angle small table 100 is reduced.

[0069] In a further embodiment of the present invention, referring to the attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 8 As shown, the first connecting rod 41 is located below the second connecting rod 42, the table board body 1 is at the maximum lifting fixed angle, the pawl 22 cooperates with the tooth groove 31 farthest from the second rotating shaft 421, and the distance between the first connecting rod 41 and the second connecting rod 42 that are away from the seat 200 is the largest. This is the most usable position of the adjustable angle small table 100. If the user continues to apply an upward lifting force to the end of the table board assembly 10 that is away from the back of the seat 200, the user can manually determine whether the adjustable angle small table 100 enters the lowered use state or the storage state to meet the user's next needs.

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

[0071] Further, see Appendix Figure 4 As shown, within at least a partial angle range of the process from the maximum lifting fixed angle to the storage state of the table top body 1, 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, thereby preventing the pawl 22 from engaging with the tooth groove 31 again during the storage process, thereby avoiding affecting the normal storage of the adjustable angle small table top 100.

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

[0073] In a further embodiment of the present invention, Figure 2 , Attachment Figure 4 and attached Figure 8 As shown, when the table top body 1 is in the storage state, the first elastic member 23 drives the pawl 22 to rotate toward the tooth groove 31 and cooperates with the tooth groove 31 closest to the second rotating shaft 421, which can ensure the normal storage of the table top assembly 10 and prevent the table top body 1 from leaving the storage state when the user does not use the adjustable angle small table top 100, thereby ensuring the reliability of the adjustable angle small table top 100, extending the service life of the adjustable angle small table top 100, and improving the user experience.

[0074] In a specific example, see the attached Figure 2 and attached Figure 3 As shown, the table top body 1 has a matching plate 13, on which a matching groove 131 is provided, the matching groove 131 is arranged opposite to the slide groove 123, and a plurality of tooth grooves 31 are arranged on the bottom wall of the matching groove 131. When the table top assembly 10 is adjusted from the lowered use state to the storage state, the pawl 22 gradually moves in the direction away from the second rotating shaft 421. When the protruding portion 221 of the pawl 22 contacts the inner wall of the side of the matching groove 131 away from the second rotating shaft 421, the pawl 22 rotates and is released from the tooth groove 31. Under the action of the first elastic member 23, the pawl 22 rotates in the direction away from the tooth groove 31 until it abuts against the stop column 211; when the table top assembly 10 is in the storage state, the first elastic member 23 drives the pawl 22 to rotate toward the tooth groove 31 and cooperate with the tooth groove 31 closest to the second rotating shaft 421. At this time, the pawl 22 is in contact with the inner wall of the side of the matching groove 131 close to the second rotating shaft 421.

[0075] In a further embodiment of the present invention, referring to the attached Figure 8As shown, the back of the seat 200 is provided with a second elastic member 201, which is used to drive the second connecting rod 42 to move in the direction away from the seat 200. When the user needs to use the adjustable angle small table 100, the table assembly 10 can be driven to separate the table assembly 10 from the back of the seat 200, making it convenient for the user to open the table assembly 10 by hand, thereby reducing the difficulty of using the adjustable angle small table 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 fixed angle to the storage state of the table board body 1, the second connecting rod 42 abuts against the second elastic member 201 to prevent the second connecting rod 42 from moving toward the back of the seat 200. When the table board body 1 is in the lowered use state, the second connecting rod 42 and the second elastic member 201 are spaced apart to prevent the second elastic member 201 from driving the second connecting rod 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 top assembly 10 enters the storage state from the most used position, the pawl 22 is initially tightly engaged with the tooth groove 31 farthest from the second rotation axis 421 among the multiple tooth grooves 31, and the user continues to apply an upward force to the end of the table top assembly 10 away from the back of the seat 200, and the pawl 22 is rotated by the force to release the engagement with the tooth groove 31 (such as Figure 4 When the pawl 22 rotates to the side of the first fixed axis 233 located on the line a toward the tooth groove 31, the first elastic member 23 drives the pawl 22 to rotate in the direction away from the tooth groove 31 until the protrusion 221 abuts against the stop column 211, so that the pawl 22 is disengaged from the tooth groove 31. 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 assembly 10 can only rotate with the second rotating axis 421 as the rotation axis. The first connecting rod 41 can only be forced to move along the length direction of the slide groove 123 toward the second rotating shaft 421 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. The user continues to lift the table top assembly 10, which can only make the second connecting rod 42 press the second elastic member 201 to move toward the back of the seat 200 until the table top body 1 is in contact with the back of the seat 200.

[0078] In some embodiments of the present invention, Figure 1 and attached Figure 2 As shown, the connecting rod assembly 20 is along the length direction of the table board assembly 10 (refer 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 further 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 2 The 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 invention, the above-mentioned adjustable angle small table 100 is provided, and the connecting rod assembly 20 includes a first connecting rod 41 and a second connecting rod 42, one end of the first connecting rod 41 and the other end of the second connecting rod 42 are suitable for being rotatably connected to the back of the seat 200 and are spaced apart in the vertical direction, the other end of the first connecting rod 41 is rotatably connected to the table assembly 10 through a first rotating shaft 411, and the other end of the second connecting rod 42 is rotatably connected to the table assembly 10 through a second rotating shaft 421, and the table assembly 10 is rotated along the table. In the width direction of the table assembly 10, the first rotating axis 411 and the second rotating axis 421 are spaced apart and the distance is adjustable, so that the table assembly 10 can be rotated relative to the seat 200 through the connecting rod assembly 20, thereby realizing the unfolding, folding and angle adjustment of the adjustable angle small table 100, so that the user can freely adjust the angle of the table assembly 10 and is no longer limited by the use angle of the backrest of the front seat 200. The practicality of the adjustable angle small table 100 can be improved, bringing convenience and comfort to the user, and improving the user's experience.

[0088] The present invention also provides a vehicle having the seat assembly 1000 according to the above embodiment.

[0089] Specifically, the vehicle includes a plurality of rows of seats 200, and the plurality of rows of seats 200 are arranged in a front-to-rear direction (eg Figure 8 The front seat 200 is provided with an adjustable small table 100 on the back when the rear passengers need to place items, and the items can be placed on the table body 1; when the rear passengers do not need to place items, the adjustable small table 100 on the back of the front seat 200 can be stored to a storage state that fits the back of the front seat 200, so as to avoid occupying the user's activity space and affecting the user's normal getting on and off the vehicle.

[0090] According to the vehicle of the embodiment of the present invention, the seat assembly 1000 mentioned above is provided, and the connecting rod assembly 20 includes a first connecting rod 41 and a second connecting rod 42. One end of the first connecting rod 41 and one end of the second connecting rod 42 are suitable for rotationally connecting with the back of the seat 200 and are spaced apart in the up and down directions. The other end of the first connecting rod 41 is rotationally connected to the table board assembly 10 through a first rotating shaft 411, and the other end of the second connecting rod 42 is rotationally 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 is adjustable, so that the table board assembly 10 can be rotated relative to the seat 200 through the connecting rod assembly 20, so as to realize the unfolding, folding and angle adjustment of the adjustable angle small table board 100, so that the user can freely adjust the angle of the table board assembly 10, and is no longer limited to the use angle of the backrest of the front seat 200, so as to improve the practicality of the adjustable angle small table board 100, bring convenience and comfort to the user, and improve the user's use experience.
