[0033] In this embodiment, the backrest 106 is driven to rotate on the seat cushion 105 by the adjustment mechanism, so that the angle of the backrest 106 can be adjusted so that the passenger's back can fit against the backrest 106, thereby improving the passenger's leaning effect. The telescopic frame 103 is pushed or pulled by the driving mechanism to make a cross movement between the bottom frame 102 and the top frame 104, so that the top frame 104 can be driven to move up and down on the base 101, and then the seat cushion 105 can be driven to move up and down on the base 101, thereby realizing automatic lifting of the seat cushion 105, so as to facilitate passenger operation and use. This solves the technical problem that the lifting of existing car seats is achieved manually, and the automatic lifting of the car seats cannot be achieved, which is inconvenient for passengers to operate and use.

[0034] Among them, the bottom frame 102 is arranged on the base 101, the driving mechanism is used to push or pull the telescopic frame 103 to move, the telescopic frame 103 is located in the bottom frame 102, the telescopic frame 103 is a diamond mesh structure, the top frame 104 is arranged on the telescopic frame 103, and partially covers the telescopic frame 103, the bottom frame 102 and the top frame 104 are both U-shaped, the seat cushion 105 is arranged on the top frame 104, the adjustment mechanism is used to adjust the angle of the backrest 106, the backrest 106 is movably arranged above the seat cushion 105 through the adjustment mechanism, and the telescopic frame 103 makes a cross movement between the bottom frame 102 and the top frame 104, so that the top frame 104 can be driven to move up and down on the base 101, and then the seat cushion 105 can be driven to move up and down on the base 101, so as to realize the automatic lifting of the seat cushion 105.

[0035] Secondly, the driving motor 107 is arranged on the base 101, the screw 108 is connected to the output end of the driving motor 107 and is located outside the driving motor 107, the slider 109 is movably connected to the screw 108 and is arranged in the telescopic frame 103, the output end of the driving motor 107 is connected to the screw 108, and drives the screw 108 to rotate along its own axis, the slider 109 has an internal thread, and the screw 108 has an external thread, the external thread of the screw 108 cooperates with the internal thread of the slider 109, so that the slider 109 can move along the trajectory of the thread outside the screw 108, thereby driving the telescopic frame 103 to perform cross movement in the bottom frame 102.

[0036] Again, the limit plate 110 is arranged at the end of the screw rod 108 away from the driving motor 107 and is located in the telescopic frame 103. By setting the limit plate 110 at the end of the screw rod 108 away from the driving motor 107, the limit plate 110 can limit the moving position of the slider 109 outside the screw rod 108 to prevent the slider 109 from slipping out of the screw rod 108 during the movement outside the screw rod 108.

[0037] At the same time, the first sliding rod 111 is slidably connected to the bottom frame 102 and passes through the telescopic frame 103. The first fixed rod 112 is fixedly connected to the bottom frame 102 and is arranged in the telescopic frame 103. The bottom frame 102 has a slide groove. The first sliding rod 111 passes through the slide groove of the bottom frame 102 and can slide horizontally in the slide groove of the bottom frame 102, thereby driving the telescopic frame 103 to perform a cross-type telescopic movement in the bottom frame 102, and then the telescopic position of the telescopic frame 103 can be limited to ensure that the telescopic frame 103 can only perform a cross-type telescopic movement.

[0038] In addition, the second sliding rod 113 is slidably connected to the top frame 104 and passes through the telescopic frame 103.

The second sliding rod 113 passes through the slide groove of the top frame 104 and can slide horizontally in the slide groove of the top frame 104. When the telescopic frame 103 performs a cross-type telescopic movement in the bottom frame 102, the part of the telescopic frame 103 located in the top frame 104 will also perform a cross-type telescopic movement, thereby driving the second sliding rod 113 to slide horizontally in the slide groove of the top frame 104, so that the telescopic position of the telescopic frame 103 can be limited to ensure that the telescopic frame 103 can only perform a cross-type telescopic movement. The telescopic frame 103, the bottom frame 102 and the top frame 104 are used together to achieve the cross-motion of the telescopic frame 103.

[0039] Finally, the control motor 115 is arranged outside the seat cushion 105, the transmission rod 116 is connected to the output end of the control motor 115 and passes through the seat cushion 105, the first gear 117 is arranged outside the transmission rod 116 and is located in the seat cushion 105, the second gear 118 is meshed with the first gear 117 and is located in the seat cushion 105, the connecting rod 119 is fixedly connected to the backrest 106 and is arranged in the second gear 118, the transmission rod 116 and the first gear 117 are coaxially arranged, the second gear 118 and the connecting rod 119 are coaxially arranged, and the control motor 11 The output end of the transmission rod 116 is connected to the transmission rod 116, and drives the transmission rod 116 to rotate along its own axis in the seat cushion 105, thereby driving the first gear 117 to rotate along its own axis. Since the second gear 118 is engaged with the first gear 117, the rotation of the first gear 117 along its own axis can drive the second gear 118 to rotate along its own axis, thereby driving the connecting rod 119 to rotate along its own axis, and further driving the backrest 106 to rotate on the seat cushion 105 along the axis of the connecting rod 119, so as to adjust the angle of the backrest 106.

[0040] When using an automatic lifting car seat of the present embodiment, when it is necessary to adjust the angle of the backrest 106, press the backrest 106 adjustment button on the car center console, so that the control module in the car center console obtains a control instruction to start the control motor 115, and controls the control motor 115 to start according to the control instruction. When the control motor 115 is started, the power output by the output end of the control motor 115 drives the transmission rod 116 to rotate along its own axis in the seat cushion 105, thereby driving the first gear 117 to rotate along its own axis. Since the second gear 118 is meshed with the first gear 117, the rotation of the first gear 117 along its own axis can drive the second gear 118 to rotate along its own axis, thereby driving the connecting rod 119 to rotate along its own axis, and then driving the backrest 106 to rotate on the seat cushion 105 along the axis of the connecting rod 119, thereby adjusting the angle of the backrest 106.

[0042] When the height of the seat cushion 105 needs to be adjusted, the seat lift button on the center console of the car is pressed, so that the control module in the center console of the car receives the control instruction to start the drive motor 107, and controls the drive motor 107 to start according to the control instruction. When the drive motor 107 is started, the power output by the output end of the drive motor 107 drives the screw 108 to rotate along its own axis, thereby driving the slider 109 to move along the thread trajectory of the screw 108 outside the screw 108, thereby driving the telescopic frame 103 to perform a cross-type reciprocating motion in the bottom frame 102, and the cross-type reciprocating motion of the telescopic frame 103 in the bottom frame 102 drives the top frame 104 to move up and down above the base 101, thereby driving the seat cushion 105 to move up and down above the base 101, and the up and down movement of the seat cushion 105 above the base 101 realizes the raising or lowering of the seat cushion 105 above the base 101.

[0043] When the seat cushion 105 is raised or lowered to a suitable height, the seat lifting button on the car center console is pressed again, so that the control module in the car center console will receive a control instruction to stop the drive motor 107, and control the drive motor 107 to stop running according to the control instruction, completing the entire automatic lifting process of the seat cushion 105, thereby completing the entire automatic lifting process of the car seat, so as to facilitate passengers to operate and use, and solves the technical problem that the lifting operation of the existing car seat is manually realized, and the automatic lifting of the car seat cannot be realized, which is inconvenient for passengers to operate and use.
