Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a seat frame frame with adjustable height on both sides. Background Technology

[0002] Height adjustment is a common feature in car seat configurations and functions. It typically relies on a four-bar linkage, with a motor driving gears or lead screws for adjustment. Usually, the height adjustment motor is located on one side of the seat frame, driving the rear or front linkage to raise the seat. However, this single-sided drive results in a locked position on one side of the seat frame, leaving the other side unrestricted. This leads to significant back-and-forth swaying of the seat frame on bumpy roads. Furthermore, the front and rear cross tubes often rotate relative to the seat cushion side panels during height adjustment, causing additional noise from the seat springs that engage with the cross tubes, resulting in inconvenience. Utility Model Content

[0003] The purpose of this utility model is to provide a seat frame frame with height adjustment function on both sides. It aims to strengthen the strength of the seat frame by arranging height adjustment mechanisms on both sides. The front and rear horizontal tubes are fixed to the side plates, so there is no rotation during the seat height adjustment process. There is no relative movement between the front and rear horizontal tubes and the seat spring, so no additional friction noise will be generated, which is more conducive to use.

[0004] To achieve the above objectives, this utility model provides a seat frame frame with adjustable height on both sides, including seat cushion side plates, which are symmetrically arranged and have a front seat cushion horizontal tube and a rear seat cushion horizontal tube welded to both sides respectively, and also includes an adjustment mechanism.

[0005] The adjustment mechanism includes a front motor mounting bracket, a lifting motor, a nut mounting bracket, a moving nut, a seat spring, a mounting device, and a linkage device. The front motor mounting bracket is welded to the front cross tube of the seat cushion. The front mounting hole of the lifting motor is connected to the front motor mounting bracket by bolts. The lifting motor lead screw is threaded to the moving nut. The lifting motor drives the lifting motor lead screw to rotate through the lifting motor drive shaft. The moving nut is welded and fixed to the nut mounting bracket. The nut mounting bracket is connected to the linkage device by bolts. The seat spring is tightly fitted to the front cross tube and the rear cross tube of the seat cushion, respectively. The mounting device is respectively set on the front and rear sides of the seat cushion side plate.

[0006] The mounting device includes a front mounting bracket and a rear mounting bracket. The front mounting bracket is located on the side of the seat side plate near the front cross tube of the seat and is arranged symmetrically. The rear mounting bracket is located on the side of the seat side plate near the rear cross tube of the seat and is arranged symmetrically.

[0007] The linkage device includes a front linkage and a rear linkage. The front linkage is fitted with the front cross tube of the seat and connected to the front mounting bracket of the seat by bolts. The rear linkage is fitted with the rear cross tube of the seat and connected to the rear mounting bracket of the seat and the nut mounting bracket by bolts.

[0008] In this case, the front cross tube of the seat cushion and the rear cross tube of the seat cushion do not rotate relative to the seat spring during the height adjustment process.

[0009] The front and rear cross tubes of the seat cushion are each coated with a corrosion-resistant coating.

[0010] This utility model discloses a seat frame frame with height adjustment on both sides. In use, the lifting motor drives the lifting motor lead screw to rotate through the lifting motor transmission shaft, thereby causing the linkage device to rotate. The rotation of the linkage device drives the rear horizontal tube of the seat cushion to move up or down. The seat cushion side plate moves up and down with the rear horizontal tube of the seat cushion, thus realizing the height adjustment of the seat frame. This application strengthens the seat frame by arranging height adjustment mechanisms on both sides. Furthermore, the front and rear horizontal tubes of the seat cushion are fixedly set with the seat cushion side plate, so there is no rotation during the seat height adjustment process. There is also no relative movement between the front and rear horizontal tubes of the seat cushion and the seat spring, which will not produce additional friction noise, thus making it more convenient to use.

Detailed Implementation

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the seat frame with adjustable height on both sides. Figure 2 This is a schematic diagram of the installation position of the moving nut 11. This utility model provides a seat frame with height adjustment functions on both sides: it includes a seat cushion side plate 4, a front seat cushion horizontal tube 1, a rear seat cushion horizontal tube 2, and an adjustment mechanism. The adjustment mechanism includes a motor front mounting bracket 9, a lifting motor 10, a nut mounting bracket 12, a moving nut 11, a seat spring 3, a mounting device, and a connecting rod device. The mounting device includes a front seat cushion mounting bracket 5 and a rear seat cushion mounting bracket 8, and the connecting rod device includes a front seat cushion connecting rod 6 and a rear seat cushion connecting rod 7. Through the aforementioned solution, the strength of the seat cushion frame is enhanced by arranging the height adjustment mechanism on both sides. Furthermore, the front and rear horizontal tubes are fixed to the side plate, preventing rotation during seat height adjustment. There is no relative movement between the front and rear horizontal tubes and the seat spring, eliminating additional friction and noise, thus improving usability. It is understood that the aforementioned solution is more user-friendly.

[0017] In this embodiment, the seat cushion side plates 4 are symmetrically arranged, and a front horizontal tube 1 and a rear horizontal tube 2 of the seat cushion are welded to both sides respectively. The front horizontal tube 1 of the seat cushion is welded and fixed to the front side of the seat cushion side plates 4, and the rear horizontal tube 2 of the seat cushion is welded and fixed to the rear side.

[0018] The motor front mounting bracket 9 is welded to the front cross tube 1 of the seat cushion. The lifting motor front mounting hole 10b of the lifting motor 10 is connected to the motor front mounting bracket 9 by bolts. The lifting motor lead screw 10c of the lifting motor 10 is threadedly connected to the moving nut 11. The lifting motor 10 drives the lifting motor lead screw 10c to rotate through the lifting motor drive shaft 10a. The moving nut 11 is welded and fixed to the nut mounting bracket 12. The nut mounting bracket 12 is connected to the connecting rod device by bolts. The seat spring 3 is tightly fitted to the front cross tube 1 and the rear cross tube 2 of the seat cushion respectively. The mounting devices are respectively set on the front and rear sides of the seat cushion side plate 4. The motor front mounting bracket 9 is welded for stability during long-term use. Bolt through holes are provided on the motor front mounting bracket 9. The lifting motor 10's front mounting hole 10b is connected to the motor front mounting bracket 9 via bolts, thus fixing the lifting motor 10. The lifting motor 10 is a dual-head motor, with drive shafts symmetrically arranged on both sides. Bevel gears are installed on both ends of the lifting motor drive shaft 10a of the lifting motor 10. A meshing bevel gear is provided on the end of the lifting motor screw 10c near the lifting motor drive shaft 10a for transmission, allowing the lifting motor 10 to drive the lifting motor screw 10c to rotate via the lifting motor drive shaft 10a. The moving nut 11 is welded to the nut mounting bracket 12, which is mounted on the connecting rod device. The mounting device is used to set the connection between the connecting rod device and the nut mounting bracket.

[0019] Secondly, the front mounting bracket 5 of the seat cushion is located on the side of the seat cushion side plate 4 near the front horizontal tube 1 of the seat cushion, and is arranged symmetrically; the rear mounting bracket 8 of the seat cushion is located on the side of the seat cushion side plate 4 near the rear horizontal tube 2 of the seat cushion, and is arranged symmetrically. Both the front mounting bracket 5 and the rear mounting bracket 8 of the seat cushion are arranged symmetrically and are provided with mating holes for connecting and installing the connecting rod device.

[0020] Then, the front connecting rod 6 of the seat cushion is tightly fitted with the front horizontal tube 1 of the seat cushion and connected to the front mounting bracket 5 of the seat cushion by bolts; the rear connecting rod 7 of the seat cushion is tightly fitted with the rear horizontal tube 2 of the seat cushion and connected to the rear mounting bracket 8 of the seat cushion and the nut mounting bracket 12 by bolts respectively. The connection of the front connecting rod 6 to the front mounting bracket 5 of the seat cushion by bolts facilitates subsequent disassembly, and the connection of the rear connecting rod 7 to the rear mounting bracket 8 of the seat cushion and the nut mounting bracket 12 by bolts facilitates subsequent disassembly.

[0021] Furthermore, the front cross tube 1 and the rear cross tube 2 of the seat cushion do not rotate relative to the seat spring 3 during height adjustment. Because the front cross tube 1 and the rear cross tube 2 are welded and fixed to the seat side plate 4, they do not rotate during seat height adjustment, and there is no relative movement between them and the seat spring 3, thus preventing additional friction noise.

[0022] Finally, both the front cross tube 1 and the rear cross tube 2 of the seat cushion are coated with a corrosion-resistant coating. This structure helps to improve the service life of the front cross tube 1 and the rear cross tube 2 of the seat cushion.

[0023] When using the seat frame frame with height adjustment function on both sides according to this utility model, during use, the lifting motor 10 drives the lifting motor lead screw 10c to rotate through the lifting motor transmission shaft 10a, and the rear connecting rods 7 of the seat cushion on both sides rotate under the cooperation of the moving nut 11. The rotation of the rear connecting rods 7 of the seat cushion drives the rear horizontal tube 2 of the seat cushion to move up or down, and the side plate 4 of the seat cushion adjusts up and down with the rear horizontal tube 2 of the seat cushion, thereby realizing the height adjustment of the seat frame. This application strengthens the strength of the seat frame by arranging the height adjustment mechanism on both sides, and the front horizontal tube 1 and the rear horizontal tube 2 of the seat cushion are fixedly set with the side plate 4 of the seat cushion. There is no rotation during the seat height adjustment process, and there is no relative movement between the front horizontal tube 1 and the rear horizontal tube 2 of the seat cushion and the seat spring 3, so no additional friction noise will be generated, which will be more conducive to use.

[0024] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
