[0050] For the above technical issues, please see Figure 1 and Figure 2The embodiment of the utility model provides a seat structure of a vehicle, including: a first driving assembly 100; a backrest assembly 200, the backrest assembly 200 is connected to the first driving assembly 100, and the first driving assembly 100 can drive the backrest assembly 200 to rotate; a table board assembly 300, the table board assembly 300 includes a table board bracket 310 and a table board 320, the table board bracket 310 is connected to the first driving assembly 100, and the table board 320 is rotatably connected to the table board bracket 310 so that the table board 320 can switch between a horizontal position away from the backrest assembly 200 and a folded position connected to the backrest assembly 200; a locking assembly 400, and the locking assembly 400 is connected to the first driving assembly 100.

[0051] In the horizontal position, the table top bracket 310 is engaged with the locking assembly 400, and the table top bracket 310 is rotationally connected to the first drive assembly 100 to keep the table top 320 in a horizontal position; in the folded position, the table top bracket 310 is disengaged from the locking assembly 400, so that the first drive assembly 100 can drive the backrest assembly 200 and the table top assembly 300 to rotate synchronously.

[0052] The seat structure of the vehicle provided by the utility model is provided with a first drive component 100 and a backrest component 200 connected to the first drive component 100, and the first drive component 100 can drive the backrest component 200 to rotate, so that the passengers in the front row of the vehicle can adjust the rotation angle of the seat structure of the front row of the vehicle according to the use requirements.

[0053] By setting up a table board assembly 300, the table board assembly 300 includes a table board bracket 310 and a table board 320 rotatably connected to the table board bracket 310. The table board 320 can be switched between a horizontal position away from the backrest assembly 200 and a folded position connected to the backrest assembly 200. When in the horizontal position, the rear passengers can use the table board 320, and when in the folded position, the rear passengers can store the table board 320.

[0054] By setting a locking assembly 400, the locking assembly 400 is connected to the first drive assembly 100. In a horizontal position, the table bracket 310 is engaged with the locking assembly 400, and the table bracket 310 is rotatably connected to the first drive assembly 100. When the first drive assembly 100 drives the backrest assembly 200 to rotate, the table bracket 310 is locked by the locking assembly 400, and the table bracket 310 and the table 320 will not rotate with the backrest assembly 200, and the table 320 can be maintained in a horizontal position, which means that when the user of the front seat structure of the vehicle adjusts the angle of the front backrest, the angle of the table 320 will not change accordingly, and will not affect the use of the table 320 by the rear passengers.

[0055] In the folded position, the table support 310 is disengaged from the locking assembly 400, and the table 320 is connected to the backrest assembly 200. When the first drive assembly 100 drives the backrest assembly 200 to rotate, the table support 310 and the table 320 will rotate synchronously with the backrest assembly 200 to achieve the storage of the table 320. This means that when the table 320 is not used by the rear passengers, the table 320 is always in the storage state regardless of whether the user of the front seat structure of the vehicle adjusts the angle of the front backrest.

[0056] In some embodiments, see Figure 1 The backrest assembly 200 includes a backrest frame 210 and a seat back (not shown) connected to the backrest frame 210. The backrest frame 210 is connected to the first driving assembly 100. The first driving assembly 100 can drive the backrest frame 210 to rotate and drive the seat back to rotate.

[0057] The backrest frame 210 is a frame-type structure, which mainly plays the role of supporting the seat back.

[0058] Specifically, there are two backrest frames 210, both of which are connected to the first drive assembly 100, and the seat back is connected between the two backrest frames 210. When the first drive assembly 100 drives the two backrest frames 210 to rotate, the seat back connected between the two backrest frames 210 will also rotate accordingly, so that the passengers in the front row of the vehicle can adjust the rotation angle of the backrest assembly 200 of the seat structure in the front row of the vehicle according to usage requirements.

[0059] It should be noted that the present invention does not limit the connection method between the seat back and the back frame 210, as long as the two can be firmly connected. For example, the seat back is connected between the two back frames 210 by screwing, welding or clamping.

[0060] In other embodiments, see Figure 1 The first driving assembly 100 includes: two connecting rod mounting members 110, the connecting rod mounting members 110 are used to connect to the seat cushion of the seat structure; a connecting rod 120, the connecting rod 120 is connected between the two connecting rod mounting members 110, and the backrest frame 210 is connected to the connecting rod 120; a driving motor (not shown), the driving motor is arranged on the connecting rod mounting member 110, and the driving motor is connected to the connecting rod 120, the driving motor can drive the connecting rod 120 to rotate relative to the connecting rod mounting member 110, and drive the backrest frame 210 to rotate relative to the connecting rod mounting member 110.

[0061] Specifically, the connecting rod mounting member 110 has a mounting hole (not shown), a skeleton bearing (not shown) is arranged in the mounting hole, and the connecting rod 120 is rotatably connected to the connecting rod mounting member 110 through the skeleton bearing. The driving motor is arranged on the connecting rod mounting member 110, and the connecting rod mounting member 110 can support the driving motor.

[0062] In this utility model, please see Figures 1 to 3 The table top bracket 310 has a clamping portion 311, and the locking assembly 400 includes: a pin mounting member 410, the pin mounting member 410 is connected to the connecting rod mounting member 110, and the pin mounting member 410 has a guide hole 411; a limit pin 420, the limit pin 420 is inserted in the guide hole 411; a second driving assembly 430, the second driving assembly 430 is connected to the limit pin 420, and the second driving assembly 430 can drive the limit pin 420 to move in the guide hole 411 along the guide direction of the guide hole 411, so that the limit pin 420 switches between a disengaged position disengaged from the clamping portion 311 and a clamping position clamped with the clamping portion 311.

[0063] Under the drive of the second drive assembly 430, the limit pin 420 can be engaged and disengaged with the engaging portion 311, thereby realizing the locking and unlocking of the table support 310. When the table support 310 is locked, the table support 310 can be decoupled from the backrest assembly 200, and the table support 310 and the table 320 will not rotate together with the backrest assembly 200. The table 320 can be kept in a horizontal position. When the user of the front seat structure of the vehicle adjusts the angle of the front backrest, the angle of the table 320 It will not change accordingly, and will not affect the use of the table 320 by the rear passengers; it can also enable the table 320 to be connected to the backrest assembly 200 when the table bracket 310 is unlocked, and the table 320, the table assembly 300, and the backrest assembly 200 are interconnected and can rotate synchronously under the drive of the first drive assembly 100. When the table 320 is not used by the rear passengers, regardless of whether the user of the front seat structure of the vehicle adjusts the angle of the front backrest, the table 320 is always in the storage state.

[0064] In some embodiments (not shown in the figure), the second driving assembly 430 is a telescopic rod disposed on the pin mounting member 410, the telescopic end of the telescopic rod is connected to the limit pin 420, and the telescopic rod can drive the limit pin 420 to move in the guide hole 411 along the guide direction of the guide hole 411. The telescopic rod technology is relatively mature and the structure of the telescopic rod is relatively simple, and the use of the telescopic rod to drive the limit pin 420 to move can reduce costs.

[0065] It should be noted that the present invention does not limit the type of telescopic rod, which can be adjusted according to demand. For example, an electric telescopic rod can be used, which is easy to control.

[0066] In other embodiments, see Figure 2 and Figure 3 The second driving assembly 430 includes: an elastic member 431, one end of the elastic member 431 is connected to the hole wall of the guide hole 411, and the other end of the elastic member 431 is connected to the limit pin 420; a pull rope 432, the pull rope 432 is connected to the limit pin 420, and the pull rope 432 extends in the direction of the limit pin 420 away from the elastic member 431, the pull rope 432 is used to pull the limit pin 420 to the disengaged position, and the elastic member 431 is used to restore the limit pin 420 to the engaged position.

[0067] Specifically, the elastic member 431 can be a spring, and there are more than two elastic members 431, which are correspondingly arranged in the guide holes 411 of the two pin mounting members 410. There are also more than two pull ropes 432, which are correspondingly connected to the two elastic members 431. Since the pull rope 432 is relatively cheap, using the pull rope 432 to pull the limit pin 420 to the disengaged position can further reduce the cost.

[0068] In this embodiment, the pull rope 432 is used to pull the limit pin 420 to the disengaged position, and the elastic member 431 is used to restore the limit pin 420 to the engaged position. External force is required only when moving the limit pin 420 to the disengaged position. When moving the limit pin 420 to the engaged position, it relies on the restoring force of the elastic member 431, and no external force is required. Therefore, the control of the limit pin 420 is relatively simple.

[0069] In some other embodiments, see Figures 1 to 3 The clamping portion 311 has a notch 312 , and the limiting pin 420 can be clamped in the notch 312 .

[0070] Specifically, the stop pin 420 is a non-rotating body, and the shape of the notch 312 matches the cross section of the stop pin 420. When the stop pin 420, which is a non-rotating body, is located in the notch 312, the inner wall of the notch 312 abuts against the surface of the stop pin 420. The stop pin 420 can limit the clamping portion 311 to prevent the clamping portion 311 from rotating relative to the stop pin 420, thereby locking the table bracket 310. Exemplarily, the cross section of the stop pin 420 is quadrilateral or hexagonal.

[0071] It should be noted that the present invention does not limit the specific structure of the clamping portion 311, as long as the clamping portion 311 can be clamped with the limiting pin 420. For example, the notch 312 on the clamping portion 311 can be replaced by a groove, and the limiting pin 420 can be clamped in the groove.

[0072] In some specific embodiments (not shown in the figure), the end of the pull rope 432 away from the limit pin 420 is a free end, which is arranged outside the seat structure of the vehicle. When the table board assembly 300 needs to rotate together with the backrest assembly 200, the free end of the pull rope 432 can be pulled manually.

[0073] In some other specific embodiments (not shown in the figure), the seat structure further includes a winding assembly, and the winding assembly is disposed on the first driving assembly 100 or the seat cushion of the seat structure.

[0074] The end of the pull rope 432 facing away from the limit pin 420 is the control end, and the control end of the pull rope 432 is connected to the winding assembly. The winding assembly winds up or releases the pull rope 432, so that the limit pin 420 can switch between a disengaged position disengaged from the clamping part 311 and a clamping position clamped with the clamping part 311.

[0075] In some specific implementations, see Figure 2 and Figure 3 , the elastic member 431 is located at the bottom of the guide hole 411; the clamping portion 311 is located on the side of the elastic member 431, and the notch 312 faces the limit pin 420; the pull rope 432 connects the limit pin 420 and the table top 320, and the rotation of the table top 320 can drive the limit pin 420 to move in the guide hole 411 along the guide direction of the guide hole 411, so that when the table top 320 is in the folded position, the limit pin 420 is in the disengaged position; when the table top 320 is in the horizontal position, the limit pin 420 is in the clamping position.

[0076] Specifically, when the table top 320 is in a horizontal position, the pull rope 432 has no traction on the limit pin 420, and the limit pin 420 is in a clamping position under the action of the elastic member 431. The table top bracket 310 is locked, and the table top bracket 310 can be decoupled from the backrest assembly 200. The table top bracket 310 and the table top 320 will not rotate with the backrest assembly 200, and the table top 320 can remain in a horizontal position.

[0077] When the table top 320 is in the folded position, the position of the pull rope 432 changes, and the pull rope 432 has a traction force on the limit pin 420. The limit pin 420 is pulled to the disengaged position under the action of the traction force, and the table top bracket 310 is unlocked. In addition, the table top 320 in the folded position is connected to the backrest assembly 200. The table top 320, the table top assembly 300, and the backrest assembly 200 are linked to each other and can rotate synchronously under the drive of the first drive assembly 100.

[0078] In this embodiment, the force of folding or unfolding the table top 320 is used to correspondingly unlock or lock the table top bracket 310. The table top bracket 310 can be unlocked or locked without the action of other external forces, which is simple to control and labor-saving.

[0079] In some embodiments, see Figure 3 The table top assembly 300 further includes a bracket bearing 330 , and the table top bracket 310 is connected to the first driving assembly 100 via the bracket bearing 330 .

[0080] In this embodiment, by providing the bracket bearing 330 , the first driving assembly 100 can improve the supporting force of the table top bracket 310 while also realizing the rotation of the table top bracket 310 .

[0081] In other embodiments, the backrest assembly 200 has a first connection portion (not shown), and the table top 320 has a second connection portion (not shown); in the folded position, the first connection portion and the second connection portion are cooperatively connected; in the horizontal position, the first connection portion and the second connection portion are disengaged.

[0082] In a specific embodiment, one of the first connecting part and the second connecting part has a snap-in hole, and the other has a snap-in. The snap-in is snapped into the snap-in hole to achieve a mating connection between the first connecting part and the second connecting part; the snap-in is pulled out of the snap-in hole to achieve a detachment between the first connecting part and the second connecting part.

[0083] In other specific embodiments, magnetic materials are provided on both the first connection part and the second connection part, and the polarity of the magnetic material on the first connection part is opposite to the polarity of the magnetic material on the second connection part. When the first connection part is close to the second connection part, the first connection part and the second connection part can be matched and connected; when the first connection part is far away from the second connection part, the first connection part and the second connection part can be separated.

[0084] An embodiment of the utility model further provides a vehicle, comprising a vehicle body and a seat structure of any of the above-mentioned vehicles arranged on the vehicle body.
