When the telescopic rod 21 is shortened, the angle adjusting assembly 3 rotates the telescopic rod 21 at the same time, and the first plate body 22 and the second plate body 23 are pulled back and finally stacked together. Moreover, when a collision occurs, the telescopic rod 21 can be shortened to drive the first plate body 22 and the second plate body 23 to switch from the unfolded state to the folded state.

[0036] In some embodiments of the present application, the first plate body 22 is provided with a connecting bracket, the connecting bracket is formed with a first connecting hole, the telescopic rod 21 is formed with a second connecting hole, and the first plate body 22 and the telescopic rod 21 are relatively rotationally connected through the shaft pin 24 penetrating through the first connecting hole and the second connecting hole. The first plate body 22 and the second plate body 23 are connected through the first hinge 25, and the second plate body 23 and the seat framework 1 are connected through the second hinge 26. In this way, 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 and unfolded states, and the structure is simple and easy to operate.

[0037] In some embodiments of the present application, the vehicle seat 100 further comprises an angle adjusting assembly 3 connected to one end of the telescopic rod 21, used for adjusting the relative angle between the telescopic rod 21 and the seat framework 1. In this way, by arranging the angle adjusting assembly 3, the angle of the table board assembly 2 can be adjusted in time and accurately, so that the table board assembly 2 is always in a horizontal state, meeting the use requirements of the passenger.

[0038] Specifically, as shown in FIG. 3, the angle adjusting assembly 3 comprises a driving member 31, a driving gear 32 and a driven gear 33. The driving member 31 is arranged on the seat framework 1, the driving gear 32 is connected to the driving shaft of the driving member 31, and the driven gear 33 is engaged with the driving gear 32 and connected to the telescopic rod 21.

The passenger can unfold or fold the table board by pressing the control switch, without manual operation, which is convenient and fast.

[0041] In some embodiments of the present application, as shown in FIG. 3, the telescopic rod 21 comprises a fixed rod 211 connected with the seat framework 1 and a movable rod 212 connected with the first plate body 22, the movable rod 212 being telescopically sleeved in the fixed rod 211 along the length direction. Specifically, when the passenger needs to use the table board, the movable rod 212 is extended from the fixed rod 211 to drive the first plate body 22 and the second plate body 23 to unfold; when the passenger does not need to use the table board, the movable rod 212 can be retracted into the fixed rod 211, so that the first plate body 22 and the second plate body 23 are stacked together to reduce the occupied space. The telescopic rod 21 has simple structure, low failure rate, is convenient to assemble and reduces the production cost.

[0042] Specifically, the movable rod 212 can be driven by hydraulic pressure or by electricity, but is not limited thereto.

Specifically, the control module receives the electrical signal of the seat framework 1 to determine the state of the table board assembly 2, and does not input the signal to the driving member 31 if the table board assembly 2 is in the folded state, and outputs the control signal for the operation of the driving member 31 if the table board assembly 2 is in the unfolded state.

[0044] Hereinafter, the vehicle seat 100 according to one specific embodiment of the present application will be described with reference to FIGS. 1-5.

[0045] Specifically, as shown in FIGS. 1-5, the vehicle seat 100 comprises a seat framework 1, a table board assembly 2, an angle adjusting assembly 3, a control switch and a control module. The table board assembly 2 comprises a telescopic rod 21, a first plate body 22 and a second plate body 23, one end of the telescopic rod 21 being rotatably connected with the seat framework 1, the other end of the telescopic rod 21 being rotatably connected with the first plate body 22, one end of the second plate body 23 being rotatably connected with the seat framework 1, the other end of the second plate body 23 being rotatably connected with the first plate body 22, the first plate body 22 and the second plate body 23 being arranged in a stacked manner in the thickness direction when the first plate body 22 and the second plate body 23 are in the folded state to reduce the occupied space, and the first plate body 22 and the second plate body 23 being arranged in sequence along the length direction of the telescopic rod 21 when the first plate body 22 and the second plate body 23 are in the unfolded state.

[0046] The angle adjusting assembly 3 comprises a driving member 31, a driving gear 32 and a driven gear 33, the driving member 31 is arranged on the seat framework 1, the driving gear 32 is connected with a driving shaft of the driving member 31, the driven gear 33 is engaged with the driving gear 32 and connected with the telescopic rod 21, a first through hole is formed on the seat framework 1, a second through hole is formed on the telescopic rod 21, the telescopic rod 21 is relatively rotated with the seat framework 1 by penetrating the first through hole and the second through hole through the rotating shaft. The control module receives the electric signal of the seat framework 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 the signal to the driving member 31; if the table board assembly 2 is in the unfolded state, the control module outputs the control signal for the operation of the driving member 31.

[0047] When the rear passenger needs to use the table board, the control switch is pressed first, the telescopic rod 21 is elongated at a certain speed after receiving the electric signal, at the same time, the angle adjusting assembly 3 rotates the telescopic rod 21 at an angle, and moves and rotates around the axis of the shaft pin 24 through the shaft pin 24, because the connecting bracket is rigidly connected with the first plate body 22, and the first plate body 22 is connected with the second plate body 23 through the first hinge 25 and can only rotate around the axis of the first hinge 25, so that the first plate body 22 rotates around the axis of the shaft pin 24 and the first hinge 25 respectively, and the rotating directions are opposite; the first plate body 22 rotates relative to the second plate body 23 through the first hinge 25, and the second plate body 23 is connected with the seat framework 1 through the second hinge 26 and rotates relative to the seat framework 1 around the axis of the second hinge 26, so as to realize the rotation of the second plate body 23 around the axis of the second hinge 26 driven by the first plate body 22.

[0048] When the telescopic rod 21 is elongated to a certain length, the first plate body 22 rotates relative to the second plate body 23 and forms a flat surface, so that the table board assembly 2 is in the unfolded state; when it is needed to be closed, the control switch is pressed, the telescopic rod 21 is retracted, drives the first plate body 22 and the second plate body 23 to move, realizes the folding closing action, so that the table board assembly 2 is in the folded state.

[0049] When the rear seat backrest is adjusted, the backrest is turned forward or backward. At this time, the vehicle control module receives the adjustment angle and direction of the seat backrest, judges the state of the table assembly 2, and controls the driving member 31. 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 to the driving member 31. After receiving the operation signal from the vehicle control module, the driving member 31 rotates at a certain speed, driving the driving gear 32 to rotate in the adjustment direction of the seat backrest. The driving gear 32 and the driven gear 33 form a gear pair, and the driven gear 33 is driven in the opposite direction. The driven gear 33 and the shaft are rigidly connected, and the shaft and the telescopic rod 21 are rigidly connected, so that the driven gear 33 drives the telescopic rod 21 to rotate around the shaft relative to the seat frame 1. The rotation direction is opposite to the adjustment direction of the seat backrest, and the rotation angle is equal. After the adjustment of the angle adjustment assembly 3, the angle of the table assembly 2 relative to the seat backrest is adjusted to maintain the horizontal state of the table assembly 2, thereby meeting the normal use requirements of the rear seat user for the table assembly 2.

[0050] When the table assembly 2 is in the unfolded state and a collision occurs, the human body hits the front of the vehicle due to inertia. At this time, the human body first contacts the table assembly 2. When the first plate body 22 is stressed, it rotates around the shaft pin 24 and the axis of the first hinge 25 and moves forward at the same time, thereby transmitting force to the telescopic rod 21 through the shaft pin 24. The movable rod 212 is retracted under the control of the driving member (such as a hydraulic drive or an electric drive) after being stressed, and 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, thereby achieving the folding and collapsing of the table assembly 2.
