The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0024] First embodiment:

[0025] See also Figures 1 to 7The present invention provides a reclining car seat frame, comprising a cushion frame 101, a backrest 102, a slider 103, a support block 104, a fixed block 105, a limiter, a driving member and a foot support 106, wherein the backrest 102 is rotationally connected with the cushion frame 101 through a moving member, wherein the moving member comprises a steering rod 107, a first gear 108, a second gear 109, a transmission rod 110, a rotating rod 111, a fixed plate 112, a sliding rod 113, a pull-out plate 114 and a first spring 115, wherein the driving member comprises a displacement sensor 116, a driving motor 117, a third gear 118, a fourth gear 119, a driving rod 120, a support plate 121, a rotating disk 122 and a connecting rod 123, and the limiter comprises a limiter plate 124, a movable rod 125, an operating plate 126 and a second spring 127.

[0026] In this embodiment, the present invention realizes the backward rotation of the backrest 102 on the seat cushion frame 101 through the movable part, so that the backrest 102 and the seat cushion frame 101 can be used together as a recliner. When the backrest 102 is laid down, the limiting fixing state of the slider 103 by the limiting plate 124 is released, and then the seat cushion frame 101 is allowed to slide backward. While sliding backward, the foot support 106 is driven to rotate by the driving part, so that the foot support 106 is automatically propped up, so that the occupant does not need to make multiple adjustments separately during use, thereby improving the use effect of the occupant, and solving the technical problem that the existing car seat frame cannot automatically prop up the foot support while the seat slides backward when it is laid down, and the occupant needs to make multiple adjustments separately during use, thereby reducing the use effect of the occupant.

[0027] The backrest 102 is rotatably connected to the seat cushion frame 101 through a moving part and is located on one side of the seat cushion frame 101. The lower surface of the seat cushion frame 101 is provided with a slider 103. The number of the sliders 103 is two and they are respectively located on the left and right sides below the seat cushion frame 101. The support block 104 and the fixed block 105 are respectively slidably provided under the sliders 103 on the left and right sides. The limiting member is located on the side of the fixed block 105 away from the support block 104, and is used to adjust the slider 103 on the right side. 03 limited fixing, the driving member is used to drive the foot support 106 to rotate, the foot support 106 is located on the side of the seat cushion frame 101 away from the backrest 102, and is located below the seat cushion frame 101, the support block 104 and the fixing block 105 are respectively placed in the car, the support block 104 and the fixing block 105 both have a slide groove, the slide grooves of the support block 104 and the fixing block 105 are both slidably provided with the slider 103, so as to drive the seat cushion frame 101 to slide forward or backward in the car.

[0028] Secondly, the steering rod 107 is rotatably connected to the cushion frame 101 and passes through the cushion frame 101. The first gear 108 is fixed outside the steering rod 107. The second gear 109 is meshed with the first gear 108 and is located outside the first gear 108. The transmission rod 110 is fixed in the second gear 109. The rotating rod 111 is arranged on the side of the transmission rod 110 away from the second gear 109, and is fixed in the backrest 102 and passes through the cushion frame 101. The cushion frame 101 has a slot, and the backrest 102 has a convex block. The convex block position of the backrest 102 The seat back 102 is in the slot of the seat cushion frame 101 and can rotate in the slot of the seat cushion frame 101, thereby driving the rotating rod 111 to rotate, and further driving the transmission rod 110 to rotate, and the second gear 109 is driven to rotate by the rotation of the transmission rod 110, thereby driving the first gear 108 to rotate, and further driving the steering rod 107 to rotate. Since the rotation of the backrest 102 on the seat cushion frame 101 is achieved by the meshing between the teeth of the first gear 108 and the second gear 109, it can ensure that the folding is smoother and provide a more comfortable riding experience for the passengers.

[0029] Again, the fixing plate 112 is arranged outside the cushion frame 101, the sliding rod 113 is detachably connected to the steering rod 107, and is slidably connected to the fixing plate 112 and penetrates the fixing plate 112, the pull-out plate 114 is arranged at one end of the sliding rod 113 away from the fixing plate 112, the first spring 115 is fixed between the fixing plate 112 and the pull-out plate 114, and is sleeved outside the sliding rod 113, the steering rod 107 is evenly distributed with through holes, the fixing plate 112 has an opening, the through hole size of the steering rod 107 is consistent with the opening size of the fixing plate 112, and The sliding rod 113 can be inserted into the opening of the fixing plate 112 and the through hole of the steering rod 107 in sequence, so that the rotation position of the steering rod 107 is limited and fixed. When the pull-out plate 114 is pulled outward, the sliding rod 113 will move in the direction away from the steering rod 107, thereby driving the first spring 115 to be stretched. Since the first spring 115 has a self-restoring effect, when the pull-out plate 114 is released, the first spring 115 will drive the pull-out plate 114 to move in the direction of returning to its original position, thereby driving the sliding rod 113 to move in the direction of returning to its original position.

[0030] At the same time, the limit plate 124 is arranged in the fixed block 105, the movable rod 125 is arranged on the side of the limit plate 124 away from the slider 103 and passes through the fixed block 105, the operating plate 126 is arranged on the end of the movable rod 125 away from the limit plate 124, the second spring 127 is fixed between the fixed block 105 and the operating plate 126, and is sleeved outside the movable rod 125, and the operating plate 126 is pulled outward, and the movable rod 125 will move in the direction away from the fixed block 105, so that the second spring 127 is stretched, so that the limit plate 12 4 moves in a direction away from the slider 103, thereby releasing the fixed state of the slider 103 in the fixing block 105. When the operating plate 126 is released, since the second spring 127 has a self-restoring effect, the second spring 127 drives the operating plate 126 to move in a direction to restore to the original position, thereby driving the movable rod 125 to move in a direction to restore to the original position, and further driving the limiting plate 124 to move in a direction to restore to the original position until the limiting plate 124 presses the slider 103 tightly, thereby realizing the limiting fixation of the slider 103 in the fixing block 105.

[0031] In addition, the displacement sensor 116 is provided on one side of the support block 104 and the fixed block 105 close to the foot bracket 106. The drive motor 117 is electrically connected to the displacement sensor 116 and is provided on the side of the support block 104 close to the fixed block 105. The third gear 118 is connected to the output shaft of the drive motor 117 and is located on the side of the drive motor 117 away from the support block 104. The fourth gear 119 is meshed with the third gear 118 and is located on the third gear 119. In addition to the three gears 118, the driving rod 120 is fixed in the fourth gear 119 and is located between the support block 104 and the fixed block 105. The support plate 121 is arranged on the lower surface of the cushion frame 101. The rotating disk 122 is connected to the driving rod 120 through a connecting belt 128 and is arranged on the side of the support plate 121 close to the foot bracket 106. The connecting rod 123 is fixed in the foot bracket 106 and is arranged on the side of the rotating disk 122 close to the foot bracket 106.

[0032] Specifically, the displacement sensor 116 can detect the moving position of the slider 103 in the support block 104 or the fixed block 105. When the displacement sensor 116 detects that the displacement between the displacement sensor 116 and the slider 103 is constantly decreasing (the distance between the displacement sensor 116 and the slider 103 is gradually approaching), the drive motor 117 is not started; when the displacement sensor 116 detects that the displacement between the displacement sensor 116 and the slider 103 is constantly increasing (the distance between the displacement sensor 116 and the slider 103 is gradually moving away), the displacement sensor 117 is not started. 6 transmits the detection result to the driving motor 117. At this time, the driving motor 117 starts to start. Through the starting of the driving motor 117, the power output from the output end of the driving motor 117 drives the third gear 118 to rotate, thereby driving the fourth gear 119 to rotate, and further driving the driving rod 120 to rotate between the supporting block 104 and the fixing block 105. Afterwards, the rotation of the driving rod 120 drives the rotating disk 122 to rotate through the connecting belt 128, thereby driving the connecting rod 123 to rotate, and further driving the foot bracket 106 to rotate along the axis of the connecting rod 123.

[0033] Finally, the displacement sensor 116 is an infrared sensor, an ultrasonic sensor or a laser sensor.

[0034] When using a reclining car seat frame of this embodiment, when it is necessary to lay down, when the pull-out plate 114 is pulled outward, the sliding rod 113 will move in a direction away from the steering rod 107, thereby driving the first spring 115 to be stretched. When the sliding rod 113 moves out of the through hole of the steering rod 107, the fixed state of the steering rod 107 is released. Then, the backrest 102 is rotated so that the protrusion of the backrest 102 rotates in the slot of the cushion frame 101, thereby driving The rotation of the rotating rod 111 can drive the transmission rod 110 to rotate, and the rotation of the transmission rod 110 can drive the second gear 109 to rotate, thereby driving the first gear 108 to rotate, and further driving the steering rod 107 to rotate. Since the rotation of the backrest 102 on the cushion frame 101 is achieved by the meshing between the teeth of the first gear 108 and the second gear 109, it can ensure smoother folding and provide a more comfortable riding experience for the passengers.

[0035] When the backrest 102 is rotated to a suitable angle, the pull-out plate 114 is released so that the tensile force on the first spring 115 disappears, so that the first spring 115 drives the pull-out plate 114 to move in the direction of returning to its original position, and then drives the sliding rod 113 to move in the direction of returning to its original position. When the sliding rod 113 is inserted into the through hole of the steering rod 107, the rotation position of the steering rod 107 is limited and fixed, so that the rotation position of the backrest 102 is limited and fixed to avoid accidentally touching the backrest 102 and causing the angle of the backrest 102 to be adjusted.

[0036] After the backrest 102 is laid down, the operating plate 126 is pulled outward, and the movable rod 125 moves in a direction away from the fixed block 105, so that the second spring 127 is stretched, thereby causing the limit plate 124 to move in a direction away from the slider 103, thereby releasing the fixed state of the slider 103 in the fixed block 105. After that, the sliders 103 on the left and right sides are respectively slid in the slide grooves of the support block 104 and the fixed block 105, thereby driving the seat cushion frame 101 to slide forward or backward in the car, allowing the seat cushion frame 101 to slide backward in the car, and at the same time, the moving position of the slider 103 in the support block 104 or the fixed block 105 is detected by the displacement sensor 116. When the displacement sensor 116 detects that the displacement between the displacement sensor 116 and the slider 103 is increasing (the displacement between the displacement sensor 116 and the slider 103 is increasing), the displacement sensor 116 detects that the displacement between the displacement sensor 116 and the slider 103 is increasing. The distance between the two gradually moves away), the displacement sensor 116 transmits the detection result to the drive motor 117. At this time, the drive motor 117 starts to start. Through the start of the drive motor 117, the power output by the output end of the drive motor 117 drives the third gear 118 to rotate, thereby driving the fourth gear 119 to rotate, and then driving the drive rod 120 to rotate between the support block 104 and the fixed block 105. After that, the rotation of the drive rod 120 drives the rotating disk 122 to rotate through the connecting belt 128, thereby driving the connecting rod 123 to rotate, and then driving the foot bracket 106 to rotate along the axis of the connecting rod 123, so as to realize the automatic propping up of the foot bracket 106. By allowing the foot bracket 106 to be automatically propped up while the seat cushion frame 101 slides backward, the occupant does not need to make multiple adjustments separately during use, thereby improving the use effect of the occupant.

[0037] When the seat cushion frame 101 slides backward to a suitable position and the operating plate 126 is released, the second spring 127 has a self-recovery effect, so that the second spring 127 will drive the operating plate 126 to move in the direction of returning to its original position, thereby driving the movable rod 125 to move in the direction of returning to its original position, and then driving the limit plate 124 to move in the direction of returning to its original position until the limit plate 124 presses the slider 103 tightly, thereby realizing the limit fixation of the slider 103 in the fixing block 105. The slider 103 is limited and fixed in the fixing block 105, so that the seat cushion frame 101 is limited and fixed in the car, so as to avoid accidental touching of the seat cushion frame 101 and causing the position of the seat cushion frame 101 to be adjusted.

[0038] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application.
