Detailed description of the specific implementation

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] Next, reference is made to Figures 1-5 Describe the vehicle seat 100 according to the first aspect embodiment of the present invention.

[0027] As Figures 1-5 shown, the vehicle seat 100 according to the first aspect embodiment of the present invention includes: a seat frame 1 and a table board assembly 2.

[0028] Specifically, the table board assembly 2 includes: a telescopic rod 21, a first plate body 22, and a second plate body 23. One end of the telescopic rod 21 is rotatably connected to the seat frame 1, and the other end of the telescopic rod 21 is rotatably connected to the first plate body 22. One end of the second plate body 23 is rotatably connected to the seat frame 1, and the other end of the second plate body 23 is rotatably connected to the first plate body 22. During normal use, the telescopic rod 21 extends to drive the first plate body 22 and the second plate body 23 to rotate relative to each other and unfold to the horizontal. When a collision occurs, the telescopic rod 21 shortens to drive the first plate body 22 and the second plate body 23 to rotate relative to each other and fold, thereby realizing the collapse and folding of the table board under force and protecting the safety of the rear passengers.

[0029] According to the vehicle seat 100 of the embodiment of the present utility model, by providing the telescopic rod 21, the folding and unfolding of the first plate body 22 and the second plate body 23 are realized, that is, the retraction and use of the table board, and the table board is collapsed when subjected to a collision force, reducing the risk coefficient of the rear occupants and improving the safety. The overall structural design is simple and ingenious, and has a wide application range.

[0030] In some embodiments of the present utility model, the first plate body 22 and the second plate body 23 are switchable between a folded state and an unfolded state. As Figure 1 shown, when the first plate body 22 and the second plate body 23 are in the folded state, the first plate body 22 and the second plate body 23 are arranged in a stacked manner in the thickness direction, reducing the occupied space. As Figure 2 shown, when the first plate body 22 and the second plate body 23 are in the unfolded state, the first plate body 22 and the second plate body 23 are arranged in sequence along the length direction of the telescopic rod 21, and the first plate body 22 and the second plate body 23 form a continuous plane. It can be understood that when the telescopic rod 21 extends, it will push the first plate body 22 to move outward, and at the same time drive the second plate body 23 to unfold until the two are in the same plane. When the telescopic rod 21 shortens, the first plate body 22 and the second plate body 23 will be pulled back and finally stacked together. And when a collision occurs, the telescopic rod 21 can shorten to drive the first plate body 22 and the second plate body 23 to switch from the unfolded state to the folded state.

[0031] In some embodiments of the present utility model, a connection bracket is provided on the first plate body 22, a first connection hole is formed on the connection bracket, a second connection hole is formed on the telescopic rod 21, and the first plate body 22 and the telescopic rod 21 are relatively rotationally connected by a shaft pin 24 passing through the first connection hole and the second connection hole. The first plate body 22 and the second plate body 23 are connected by a first hinge 25, and the second plate body 23 and the seat frame 1 are connected by a second hinge 26. Thus, the first plate body 22 and the second plate body 23 can rotate within a certain range, which helps to keep the table board assembly 2 stable when switching between the folded state and the unfolded state, and has a simple structure and is convenient to operate.

[0032] In some embodiments of the present utility model, the vehicle seat 100 further includes: an angle adjustment assembly 3, and the angle adjustment assembly 3 is connected to one end of the telescopic rod 21 for adjusting the relative angle between the telescopic rod 21 and the seat frame 1. Thus, by providing the angle adjustment assembly 3, the angle of the table board assembly 2 can be adjusted timely and accurately, so that the table board assembly 2 is always in a horizontal state to meet the use requirements of the occupants.

[0033] Specifically, as Figure 3As shown, the angle adjustment assembly 3 includes a driving member 31, a driving gear 32, and a driven gear 33. The driving member 31 is provided on the seat frame 1. The driving gear 32 is connected to the driving shaft of the driving member 31. The driven gear 33 meshes with the driving gear 32 and is connected to the telescopic rod 21. Thus, the structure of the angle adjustment assembly 3 is simple. The cooperation between the driving gear 32 and the driven gear 33 ensures the adjustment accuracy of the angle adjustment assembly 3, improves the stability of the table assembly 2, and enhances the reliability of the table assembly 2.

[0034] In some embodiments of the present utility model, a first through hole is formed on the seat frame 1, and a second through hole is formed on the telescopic rod 21. The telescopic rod 21 and the seat frame 1 rotate relative to each other by a rotating shaft passing through the first through hole and the second through hole. Thus, the telescopic rod 21 can rotate relative to the seat frame 1 within a certain range. The connection structure is simple, which helps the table assembly 2 to remain stable when switching between the folded state and the unfolded state, improving the comfort of the occupant and the practicality of the seat.

[0035] In some embodiments of the present utility model, the vehicle seat 100 further includes a control switch. The control switch is electrically connected to the telescopic rod 21 and is used to start or stop the telescopic movement of the telescopic rod 21, thereby controlling the unfolding and folding of the table. The passenger can unfold or fold the table by pressing the control switch without manual operation, which is convenient and fast.

[0036] In some embodiments of the present utility model, as Figure 3 shown, the telescopic rod 21 includes a fixed rod 211 and a movable rod 212. The fixed rod 211 is connected to the seat frame 1, and the movable rod 212 is connected to the first plate body 22. The movable rod 212 is telescopically sleeved inside the fixed rod 211 along the length direction. Specifically, when the passenger needs to use the table, the movable rod 212 extends out of the fixed rod 211, driving the first plate body 22 and the second plate body 23 to unfold; when the passenger does not need to use the table, the movable rod 212 can retract into the fixed rod 211, so that the first plate body 22 and the second plate body 23 are stacked together, reducing the occupied space. The structure of the telescopic rod 21 is simple, with low failure rate, easy to assemble, and reducing the production cost.

[0037] Specifically, the movable rod 212 can be driven by hydraulic pressure or by electricity, but is not limited thereto.

[0038] In some embodiments of the present utility model, the vehicle seat 100 further includes a control module. The control module is electrically connected to both the seat frame 1 and the driving member 31. Specifically, the control module receives the electrical signal of the seat frame 1, judges the state of the table assembly 2. If the table assembly 2 is in the folded state, the control module does not input a signal to the driving member 31; if the table assembly 2 is in the unfolded state, the control module outputs a control signal for the driving member 31 to operate.

[0039] The following will refer to Figures 1-5 describe the vehicle seat 100 according to a specific embodiment of the present utility model.

[0040] Specifically, as Figures 1-5 shown, the vehicle seat 100 includes: a seat frame 1, a table board assembly 2, an angle adjustment assembly 3, a control switch, and a control module. The table board assembly 2 includes: a telescopic rod 21, a first plate body 22, and a second plate body 23. One end of the telescopic rod 21 is rotatably connected to the seat frame 1, the other end of the telescopic rod 21 is rotatably connected to the first plate body 22, one end of the second plate body 23 is rotatably connected to the seat frame 1, and the other end of the second plate body 23 is rotatably connected to the first plate body 22. When the first plate body 22 and the second plate body 23 are in the folded state, the first plate body 22 and the second plate body 23 are stacked in the thickness direction, reducing the occupied space. When the first plate body 22 and the second plate body 23 are in the unfolded state, the first plate body 22 and the second plate body 23 are arranged in sequence along the length direction of the telescopic rod 21.

[0041] The angle adjustment assembly 3 includes: a driving member 31, a driving gear 32, and a driven gear 33. The driving member 31 is arranged on the seat frame 1, the driving gear 32 is connected to the driving shaft of the driving member 31, the driven gear 33 is meshed with the driving gear 32 and is connected to the telescopic rod 21. A first through hole is formed on the seat frame 1, a second through hole is formed on the telescopic rod 21, and the telescopic rod 21 and the seat frame 1 rotate relative to each other through a rotating shaft passing through the first through hole and the second through hole. The control module receives the electrical signal of the seat frame 1, judges the state of the table board assembly 2. If the table board assembly 2 is in the folded state, the control module does not input a signal to the driving member 31; if the table board assembly 2 is in the unfolded state, the control module outputs a control signal for the driving member 31 to operate.

[0042] When a rear row passenger needs to use the table board, first press the control switch. After receiving the electrical signal, the telescopic rod 21 extends at a certain speed, and drives the movement of the connecting bracket and the rotation around the axis of the pin 24 through the pin 24. Since the connecting bracket is rigidly connected to the first plate body 22, and the first plate body 22 and the second plate body 23 are connected by a first hinge 25 and can only rotate around the axis of the first hinge 25, the first plate body 22 rotates around the axes of the pin 24 and the first hinge 25 respectively, and the rotation directions are opposite; the first plate body 22 and the second plate body 23 rotate relative to each other through the first hinge 25, and the second plate body 23 is connected to the seat frame 1 body through a second hinge 26 and rotates relative to the seat frame 1 around the axis of the second hinge 26, so as to realize the first plate body 22 driving the second plate body 23 to rotate around the axis of the second hinge 26.

[0043] When the telescopic rod 21 extends to a certain length, the first plate body 22 rotates relative to the second plate body 23 to form a flat surface, so that the table board assembly 2 is in the unfolded state; when it needs to be closed, press the control switch, the telescopic rod 21 retracts, drives the first plate body 22 and the second plate body 23 to move, and realizes the folding and closing action, so that the table board assembly 2 is in the folded state.

[0044] When the angle of the front row seat back is adjusted, the seat back flips forward or backward of the vehicle. At this time, the vehicle control module receives the adjustment angle and direction of the seat back, judges the state of the table board assembly 2. If the table board assembly 2 is in the folded state, the control module does not input a signal to the driving part 31; if the table board assembly 2 is in the unfolded state, the control module outputs a control signal for the driving part 31 to operate; after the driving part 31 receives the operation signal from the vehicle control module, the driving part 31 rotates at a certain speed, drives the driving gear 32 to operate in the adjustment direction of the seat back, the driving gear 32 and the driven gear 33 form a gear pair, the gears mesh to drive the driven gear 33 to rotate in the opposite direction, the driven gear 33 is rigidly connected to the rotating shaft, and the rotating shaft is rigidly connected to the telescopic rod 21. Thus, the telescopic rod 21 is driven by the driven gear 33 to form a relative movement around the rotating shaft with the seat frame 1, its rotation direction is opposite to the adjustment direction of the seat back, and the rotation angle is equal. Through the adjustment of the above angle adjustment assembly 3, the table board assembly 2 realizes angle adjustment relative to the seat back to keep the table board assembly 2 in a horizontal state, so as to meet the normal use requirements of the rear row users for the table board assembly 2.

[0045] When the table board assembly 2 is in the unfolded and in-use state and a collision occurs, the human body impacts forward of the vehicle due to inertia. At this time, the human body first contacts the table board assembly 2. When the first plate body 22 is stressed, it rotates around the axis of the pin 24 and the first hinge 25 and moves forward at the same time, so as to transmit the force to the telescopic rod 21 through the pin 24. After the movable rod 212 is pressed, it retracts under the control of a driving part (such as hydraulic drive or electric drive). At the same time, the movement of the first plate body 22 and the first hinge 25 drives the second plate body 23 to rotate upward around the axis of the second hinge 26, realizing the folding and collapse of the table board assembly 2.

[0046] The vehicle according to the second aspect embodiment of the present invention includes the vehicle seat 100 according to the first aspect embodiment of the present invention above.
