DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The function of the car seat frame is to bear load, transmit torque, and increase stability. Similar to human bones, it is the installation carrier of seat covers, seat foam, electronic parts, plastic parts and other parts. The quality of the seat frame directly determines the comfort of the user. However, in some cases of long-term driving or frequent load-bearing, the seat sponge will be subjected to continuous and large pressure, which will cause the seat sponge to collapse, thus affecting the use.

[0021] Embodiment 1

[0022] After long-term use, the existing car seat cushions are prone to collapse and affect the use. Figure 1-Figure 3 The present embodiment proposes a skeleton structure of a car seat cushion, which can re-support the collapsed seat cushion sponge, thereby reducing the extent of its collapse. It is mainly composed of a base 1, on which is provided a support component 2 for supporting the seat cushion sponge. Some seat cushion sponges may have quality problems during the production process, such as uneven density, insufficient elasticity, etc., which will cause the seat cushion sponge to collapse after being used for a period of time. The present embodiment can support the collapsed seat cushion sponge through the provision of the support component 2, reduce the extent of the seat cushion sponge collapse, and ensure that the car seat can be used normally.

[0023] In order to solve the impact of the collapse of the cushion sponge on the use of the car seat, this embodiment realizes the function of re-supporting the cushion sponge through the setting of the support component 2, thereby ensuring the normal use of the car seat. Figure 2 As shown, the support assembly 2 includes a support plate 21 arranged in the base 1, and the upper part of the support plate 21 contacts the cushion sponge, and an adjustment shaft 22 is rotatably installed on both sides of the support plate 21, and an adjustment sleeve 24 is slidably sleeved on the outside of the adjustment shaft 22, and a control cavity 25 is arranged inside the adjustment sleeve 24, and a baffle 23 fixedly connected to the adjustment shaft 22 is abutted in the control cavity 25, and a lifting gear 213 is coaxially fixed to the outside of the adjustment sleeve 24, and a lifting rack 214 fixedly connected to the base 1 is meshed on one side of the lifting gear 213. When in use, the base 1 is first fixed inside the car, and then the cushion sponge is sleeved and installed on the bottom At the upper part of the seat 1, a support plate 21 arranged in the base 1 can support the seat cushion sponge. When the seat cushion sponge collapses after long-term use and affects its use, the user can drive the lifting gear 213 to rotate by rotating the adjusting sleeve 24. Since the lifting gear 213 is meshed with the lifting rack 214, the lifting gear 213 will move on the lifting rack 214, thereby driving the support plate 21 to squeeze the seat cushion sponge upward, reducing the extent of its collapse and maintaining the normal use of the car seat. In addition, the mutual interference between the baffle 23 and the control chamber 25 will prevent the adjusting sleeve 24 from falling off the adjusting shaft 22.

[0024] A pawl 26 elastically hinged to the adjusting shaft 22 is provided in the control cavity 25, and a ratchet 27 fixed to the inner wall of the control cavity 25 is meshed on the outside of the pawl 26. The arrangement of the ratchet 27 and the pawl 26 enables the lifting gear 213 to rotate only in one direction, that is, to move upward along the lifting rack 214 without falling off downward, thereby improving the stability of the adjustment of the support plate 21.

[0025] One end of the adjusting sleeve 24 and the support plate 21 are respectively provided with a corresponding adsorption magnetic ring 1 28 and an adsorption magnetic ring 2 29, and the adsorption magnetic ring 1 28 and the adsorption magnetic ring 2 29 repel each other. The mutually repelling adsorption magnetic ring 1 28 and the adsorption magnetic ring 2 29 will make the ratchet 27 and the pawl 26 always meshed together, so that the support plate 21 will not move downward. When the support plate 21 needs to be adjusted downward, it is only necessary to press the adjusting sleeve 24 inward to separate the ratchet 27 and the pawl 26 in the control chamber 25, so as to release the restriction on the descent of the support plate 21, so that the support plate 21 can be freely adjusted in position. After the adjustment is completed, the adjusting sleeve 24 is released. Under the mutual repulsion of the adsorption magnetic ring 1 28 and the adsorption magnetic ring 29, the ratchet 27 will mesh with the pawl 26 again to limit the downward movement of the support plate 21.

[0026] Embodiment 2

[0027] On the basis of the first embodiment, the technical solution proposed in the first embodiment is used to solve the shortcoming that the existing automobile seat cushion is easy to collapse and affect the use after long-term use. However, the magnet may indeed demagnetize after a period of time, and this process will be accelerated under the influence of various factors such as high temperature, low temperature or physical damage. When the adsorption magnetic ring 1 28 or the adsorption magnetic ring 2 29 is demagnetized, the adjustment sleeve 24 may be affected by factors such as vibration and move to the side of the support plate 21, thereby causing the ratchet 27 and the pawl 26 to separate, so that the support plate 21 loses the downward resistance and moves downward, thereby reducing the support of the support plate 21 to the cushion sponge, affecting the user's experience.

[0028] Reference Figure 1-Figure 3 A movable ball 210 is movably installed at one end of the adjusting sleeve 24, a pulling link 211 is fixedly installed on the movable ball 210, and a gravity ball 212 is fixedly installed at one end of the pulling link 211. In this embodiment, through the setting of the gravity ball 212, the connection between the pulling link 211 and the movable ball 210 and the adjusting sleeve 24 is utilized, so that the adjusting sleeve 24 has a tendency to move away from the support plate 21, but under the resistance of the baffle 23, it will not disengage from the adjusting shaft 22, so that the ratchet 27 and the pawl 26 are always engaged and will not separate easily, further improving the stability of the support plate 21 in supporting the seat cushion sponge.

[0029] The support plate 21 is tilted inside the base 1. Due to the influence of factors such as the roughness of the seat cushion and the vibration of the vehicle during driving, the passenger generally tends to slide forward when in the car. In order to avoid falling off the car seat, the passenger will use both feet to prevent his body from sliding down, which makes it impossible for the passenger to sit comfortably in the car. For the sake of passenger comfort, the support plate 21 is tilted in this embodiment, and the bottom end is in contact with the seat back, so that the passenger can move closer to the seat back under the action of his own gravity, and will not feel that he is about to fall off the car seat, thereby improving the user's riding experience.

[0030] The support plate 21 is a hollow structure. Figure 1 As shown, the base 1 is provided with many hollow holes, which, in combination with the hollow structure of the support plate 21, can reduce the weight of the car seat, which is in line with the lightweight manufacturing concept of modern cars.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
