[0002] The driver of the mechanical lumbar support used in car seats usually consists of two parts: a motor and a cable traction box. When the support height of the seat needs to be adjusted, the cable traction box is driven by the motor to release or retract the cable from the cable traction box.

[0003] Publication (announcement) No. CN206374604U discloses a grid-type electric lumbar support and a car seat with the lumbar support. The motor and the wire traction box of the electric drive are separate and arranged in an L-shape. When the electric drive is installed on the grid, the motor and the wire traction box need to be assembled first, and then the motor and the wire traction box need to be fixedly connected to the grid respectively. However, in actual seat assembly, the grid is often installed on the seat frame, and then the motor and the wire traction box need to be fixedly connected to the grid respectively. At this time, the motor and the wire traction box with an L-shaped layout face the problem that they are not easy to be stuffed into the seat due to their large entry size, and after being stuffed into the seat, the space is small, especially the space at the motor at the bottom of the grid is even smaller, which makes the fixing operation very inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide a box-type mechanical lumbar support and a car seat, so as to solve the technical problem that the existing L-shaped electric drive has a large entry size and the motor is located at the bottom of the grid, which makes it difficult to assemble with the grid.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments that can be realized by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example

[0027] like Figure 1 and Figure 2As shown, the utility model provides a box-type mechanical waist support, comprising: a pair of docking plates 100, each of which is provided with a motor accommodating semi-recess 110 on one side of the middle, a transmission gear accommodating semi-recess 120 on the upper side of the middle, and a wire assembly accommodating semi-recess 130 on the other side of the middle, so as to combine with the motor when the cover is closed. Figure 3 , respectively enclosing the motor 200, the transmission gear 300 and the wire assembly 400; Figure 2 As shown, a plurality of steel wire fastening tabs 510 are arranged on a docking plate 100 to form a steel wire fastening portion 520 with the plate wall to be fastened with the steel wire grid 600.

[0028] The present box-type mechanical lumbar support is provided with a motor accommodating semi-recess 110, a transmission gear accommodating semi-recess 120, and a wire assembly accommodating semi-recess 130 on a pair of docking plates 100. When the two docking plates 100 are covered, the motor 200, the transmission gear 300, and the wire assembly 400 are wrapped and a transmission connection is formed between them, thereby storing the motor 200, the transmission gear 300, and the wire assembly 400 into a plate shape, which is convenient for inserting into the seat during assembly. In addition, a wire buckle tab 510 can be provided on the docking plate 100, so that the present box-type mechanical lumbar support can be directly buckled with the wire mesh 600. The fixation can be completed during the insertion process, and there is no need to perform fixing operations after insertion. This reduces the difficulty of assembly and simplifies the assembly process.

[0029] like Figure 1 As shown, since the wire pulling assembly 400 performs a linear motion when pulling the wire, the motor accommodating semi-recess 110 and the wire pulling assembly accommodating semi-recess 130 can both be arranged along the length direction of the docking plate 100 to fully utilize the space of the docking plate 100 along the length direction. The docking plate 100 no longer needs to be extended in other directions to provide space for the wire pulling assembly 400. While ensuring that the wire pulling assembly 400 has enough space for pulling the wire, the volume of the docking plate 100 is kept at a small level, making it easy to fit into the seat during assembly.

[0030] In at least one embodiment, the box-type mechanical waist support pull line is as follows. Figure 3 As shown, the output gear 210 on the rotating shaft of the motor 200 is engaged with the transmission gear 300 enclosed by the transmission gear receiving semi-recess 120; Figure 1 and Figure 2 The bottom of the half recess 130 of the pull wire assembly is provided with a pull wire through hole 131; Figure 3 As shown, the wire pulling assembly 400 may include: a rotating column 410, which is rotatably arranged in a wire pulling assembly accommodating semi-recess 130, and one end of which is a transmission gear portion 411 to engage with the transmission gear 300, and the lower part of the rotating column 410 is a wire pulling thread portion 412; Figure 3As shown, the wire pull slider 420 is threadedly matched with the wire pull thread portion 412 to slide on the wire pull thread portion 412 when the rotating column 410 is driven by the transmission gear 300; Figure 2 and Figure 4 A pair of wire clamps 430 are respectively arranged on one side of the wire slider 420 and extend through the wire through hole 131 to accommodate the corresponding wire assembly semi-recess 130 for clamping the wire.

[0031] like Figure 4 As shown, each docking plate 100 is provided with a wire guide slot 140, which is located along the length of the wire through-hole 131. Each of these slots 140 engages with one end of a wire guide 700. One end of the wire can pass through the guide 700 and exit through the slot 140, where it is captured by the wire clamp 430. The end of the wire outside the guide 700 remains exposed for connection to the seat frame.

[0032] like Figure 4 As shown, two wire guides 700 extend from corresponding wire guide slots 140, bend and extend toward either side of the docking plate 100, then extend straight along the side bars 610 of the wire mesh 600, bend and extend again to intersect and extend out of the side bars 610. Each side bar 610 is provided with at least three tie straps 530, and is secured to the wire guides 700 above, within the height of, and below the docking plate 100. With the wire guides 700 fixedly connected to the side bars 610 above, within the height of, and below the docking plate 100, the motor 200 drives the wire slider 420 inward, pulling the wire into the wire through hole 131. This causes a large area of the wire mesh 600 to be lifted. When this area is lifted, the lower portion of the docking plate 100 is lifted to a greater height, while the upper portion is lifted to a relatively smaller height, achieving a comfortable, diagonal lifting effect that better fits the waist curve of the human body.

[0033] In at least one embodiment, a car seat is further provided, comprising: the box-type mechanical lumbar support as described above disposed therein.

[0034] The technical solution and technical effects of the box-type mechanical lumbar support of the car seat, which reduces the difficulty of assembly while simplifying the assembly process, have been described above and will not be repeated here.

[0035] In summary, the present box-type mechanical lumbar support is configured with a motor accommodating semi-recess 110, a transmission gear accommodating semi-recess 120, and a wire assembly accommodating semi-recess 130 respectively provided on a pair of docking plates 100. This allows the motor 200, the transmission gear 300, and the wire assembly 400 to be wrapped and a transmission connection to be formed between them when the two docking plates 100 are covered. This allows the motor 200, the transmission gear 300, and the wire assembly 400 to be stored in a plate shape, making it easier to insert them into the seat during assembly. Furthermore, a wire buckle tab 510 can be provided on the docking plate 100, allowing the present box-type mechanical lumbar support to be directly buckled with the wire mesh 600. This allows for fixation during the insertion process, eliminating the need for subsequent fixing operations. This simplifies the assembly process while reducing assembly difficulty.
