[0040] Combine the following Figure 1-Figure 8 The technical solution provided by the utility model is described in more detail.

[0041] Embodiment 1:

[0042] The folding chair provided by the utility model comprises a shell 1, a support frame 4, a seat portion 2 and a chair back 3, wherein: a horizontal track 6 is arranged at the bottom of the shell 1, the horizontal track 6 extends out of the shell 1, and the support frame 4 can slide back and forth along the horizontal track 6, so that the support frame 4 is recovered into the shell 1 or extends out of the shell 1; a vertical track 5 is arranged on the support frame 4, and the chair back 3 can be raised and lowered along the vertical track 5; the connecting side of the seat portion 2 is rotatably connected with the chair back 3 through a rotating shaft portion 8, and the rotating shaft portion 8 can drive the seat portion 2 to rotate with the central axis of the rotating shaft portion 8 as the axis center, so that the free side of the seat portion 2 moves in a direction toward or away from the chair back 3, thereby making the seat portion 2 in a folded state or an opened state.

[0043] As an alternative embodiment, see Fig. 9 As shown, Fig. 9 It is a schematic diagram of the structure of the housing 1 and the bar stool, that is, Fig. 9 The structure inside the housing 1 is omitted.

[0044] The housing 1 of this embodiment includes a housing cavity 100 having an open side. At least a portion of the horizontal track 6 is located in the housing cavity 100 and extends out of the open side.

[0045] When in the fully retracted state, the seat 2 is folded on the backrest 3, and the support frame 4, the backrest 3, and the seat 2 are located in the accommodating cavity 100 in the shell 1, which can greatly reduce the occupied space, facilitate storage, and release the space in the car. When the seat 2 needs to be opened, the support frame 4 drives the backrest 3 and the seat 2 to slide out of the shell 1 along the horizontal track 6, and the backrest 3 rises along the vertical track 5 to a height that does not interfere with the shell 1, and the shaft 8 drives the seat 2 to rotate around the shaft 8, and is in the open state.

[0046] When it is necessary to retract the support frame 4, the seat back 3, and the seat portion 2, the seat portion 2 is first rotated around the rotation axis portion 8 to a position close to the seat back 3 and folded, and then the seat back 3 and the seat portion 2 are lowered along the vertical track 5, and the support frame 4 carries the seat back 3 and the seat portion 2 along the horizontal track 6 to be retracted into the shell 1.

[0047] In the folding seat of this embodiment, when the seat portion 2 is opened, the support frame 4 drives the seat back 3 and the seat portion 2 to slide out of the shell 1 along the horizontal track 6, and the seat back 3 rises along the vertical track 5 to a height that does not interfere with the shell 1, and the rotating shaft 8 drives the seat portion 2 to rotate and is in an open state. When the seat is retracted into the shell 1, the opposite is true. When the folding seat is not in use, the seat portion 2 can be folded onto the seat back 3 and retracted into the shell 1 together, reducing the space occupied and freeing up space in the car. It can also be opened and used normally without affecting the driver and passengers.

[0048] As an optional embodiment, the folding seat further includes a first driving device, which is drivingly connected to the rotating shaft portion 8 and is used to drive the rotating shaft portion 8 to rotate around its own axis.

[0049] The first driving device can be a motor, whose output end is drivingly connected to the shaft portion 8 for driving the shaft portion 8 to rotate. When the shaft portion 8 rotates, the seat portion 2 is driven to rotate, so that the free end of the seat portion 2 moves toward the chair back 3 for folding.

[0050] As an alternative embodiment, see Figure 3-Figure 6 As shown, a rotation limiting portion 7 is fixed to the connection side of the seat portion 2 , and the rotation limiting portion 7 is fixedly connected to the rotation shaft portion 8 for limiting the rotation angle of the seat portion 2 .

When the seat portion 2 is in a folded state or an opened state, the two opposite side walls of the arc-shaped groove 71 respectively abut against the baffle 31, thereby limiting the rotation angle of the seat portion 2.

[0052] The angle of the arc groove 71 can be set according to actual conditions and is not limited here.

[0053] The baffle 31 moves relative to the arc groove 71 (the arc groove 71 moves, the baffle 31 does not move, and relative movement occurs between the two), which can limit the rotation angle of the seat part 2, thereby realizing the folding or opening of the seat part 2 and the chair back 3, and preventing the seat part 2 from being over-opened and affecting the comfort of passengers when sitting down.

[0054] As an optional implementation, combining Figure 3 and Figure 7 As shown, Figure 7 The dotted line in the middle indicates the position of the backrest. The folding seat also includes a lifting drive mechanism, which includes a lifting drive device 91 (such as a motor), a first lead screw 92 and a first nut portion 93, wherein: the first lead screw 92 is rotatably connected to the support frame 4 and is vertically arranged, the lifting drive device 91 is transmission-connected to the first lead screw 92 for driving the first lead screw 92 to rotate forward or reversely, the first nut portion 93 is threadedly connected to the first lead screw 92, and the first nut portion 93 is fixedly connected to the backrest 3; a first slider 94 is fixed to the backrest 3, and the first slider 94 is slidably connected to the vertical track 5.

[0055] The lifting drive mechanism adopts a matching structure of a motor and a first lead screw 92. The first lead screw 92 rotates forward or reversely to drive the first nut portion 93 to reciprocate along the axial direction of the first lead screw 92. The first slider 94 cooperates with the vertical track 5 to play a guiding role, thereby limiting the first nut portion 93 from driving the chair back 3 and the seat portion 2 to rise and fall vertically along the vertical track 5.

[0056] As an optional implementation, combining Figure 3 and Figure 8 As shown, the folding seat also includes an extension drive mechanism, which includes an extension drive device 101, a second lead screw 102 and a second nut portion 103, wherein: the second lead screw 102 is rotatably connected to the horizontal track 6 and is horizontally arranged, the extension drive device 101 is transmission connected to the second lead screw 102, and is used to drive the second lead screw 102 to rotate forward or reversely, the second nut portion 103 is threadedly connected to the second lead screw 102, and the second nut portion 103 is fixedly connected to the support frame 4; a second slider 104 is fixed on the support frame 4, and the second slider 104 is slidably connected to the horizontal track 6.

[0057] The extension drive mechanism adopts a matching structure of a motor and a second lead screw 102. The second lead screw 102 rotates forward or reversely to drive the second nut portion 103 to reciprocate along the axial direction of the second lead screw 102. The second slider 104 cooperates with the horizontal track 6 to play a guiding role, thereby limiting the second nut portion 103 from driving the support frame 4 to extend out of the shell 1 or retract into the shell 1 along the horizontal track 6.

[0058] In the folding seat of this embodiment, when the seat 2 needs to be opened, the extension drive mechanism drives the support frame 4 to drive the backrest 3 and the seat 2 to slide out of the shell 1 along the horizontal track 6, the lifting drive mechanism drives the backrest 3 to rise along the vertical track 5 to a height that does not interfere with the shell 1, and the rotation drive device drives the shaft portion 8 to rotate, thereby driving the seat 2 to rotate around the shaft portion 8, so that the seat 2 is in the open state. When the support frame 4, the backrest 3, and the seat 2 need to be recovered, the seat 2 first rotates around the shaft portion 8 to a position close to the backrest 3, and then folds, and then the backrest 3 and the seat 2 descend along the vertical track 5, and the support frame 4 carries the backrest 3 and the seat 2 along the horizontal track 6 to be recovered into the shell 1. When in the fully recovered state, the seat 2 is folded on the backrest 3, and the support frame 4, the backrest 3, and the seat 2 are located in the accommodating cavity 100 in the shell 1, which can greatly reduce the occupied space, facilitate storage, and release the space in the car.
