Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a zero-gravity seat lifting and adjustment structure. Background Technology

[0002] Car seats are one of the most important car accessories, and their comfort is of paramount importance. Currently, people have increasingly higher requirements for seat comfort. The seat posture is determined by the seat frame, which includes the seat back angle, leg rest extension length and angle, seat frame height and angle, etc., and is one of the main factors affecting seat comfort.

[0003] Existing zero-gravity seats generally lack adjustment mechanisms, making it impossible to adjust the seat's tilt angle. Due to differences in body shape and other factors among drivers and passengers, existing zero-gravity seats often fail to place the driver or passenger in the most comfortable position, making it difficult to allow the spine to relax and move freely. Utility Model Content

[0004] The purpose of this invention is to provide a zero-gravity seat lifting and adjustment structure to solve the problem that the tilt angle of existing zero-gravity seats cannot be adjusted.

[0005] To achieve the above objectives, this utility model provides a zero-gravity seat lifting and adjustment structure, including a base support and a seat frame mechanism. The seat frame mechanism is disposed on the upper side of the base support, and a drive mechanism is disposed on the base support. It also includes an adjustment mechanism.

[0006] The adjustment mechanism includes a first support, a second support, a toothed bracket, an auxiliary bracket, a connecting arm, a connecting piece, and a power device. The first support is located on the front side of the base bracket and is symmetrically arranged. The second support is located on the rear side of the base bracket and is symmetrically arranged. The toothed bracket is rotatably connected to the first support and meshes with the gear on the drive motor of the power device. The auxiliary bracket is rotatably connected to the first support on the side away from the power device. The auxiliary bracket is rotatably connected to the connecting piece. One end of the connecting piece is fixedly mounted on the seat frame mechanism, and the other end is rotatably connected to the toothed bracket and the auxiliary bracket. One end of the connecting arm is rotatably connected to the first support and the second support respectively, and the other end is welded to the seat frame mechanism. The power device is installed on the first support on the side away from the auxiliary bracket. After installation, its drive motor is at a 45° angle to the horizontal plane of the base bracket.

[0007] The seat frame mechanism includes a seat frame skeleton and a mating device. The seat frame skeleton is disposed above the base support; the mating device is disposed on the seat frame skeleton.

[0008] The mating device includes a skeleton strip and a first skeleton plate, wherein the skeleton strip is welded to the seat frame skeleton; and the first skeleton plate is welded to the skeleton strip.

[0009] The mating device further includes a second skeleton plate, which is welded to the skeleton strip and located away from the first skeleton plate.

[0010] The drive motor of the power unit is equipped with a brake mechanism.

[0011] This utility model discloses a zero-gravity seat lifting and adjustment structure. During adjustment, the user controls the power unit via control buttons inside the vehicle. After the power unit is activated, the gear on its output side meshes with the toothed bracket, driving the toothed bracket to rotate. The rotation of the toothed bracket drives the connecting piece to move, and the auxiliary bracket moves simultaneously. The connecting arm rotates in coordination, thereby lifting the seat frame mechanism. At this time, the seat tilt angle increases. Conversely, when the drive motor of the power unit rotates in the opposite direction, the seat tilt angle decreases, thus completing the adjustment and solving the problem that the tilt angle of existing zero-gravity seats cannot be adjusted.

Figure 2 This is a structural schematic diagram of the auxiliary support 106. Figure 3 This is a schematic diagram of the raised state of a zero-gravity seat lifting and adjustment structure. This utility model provides a zero-gravity seat lifting and adjustment structure, including a base support 101, a seat frame mechanism, a drive mechanism 102, and an adjustment mechanism.

This solution solves the problem that existing zero-gravity seats cannot be adjusted in tilt angle; therefore, it enables seat tilt angle adjustment.

[0020] In this embodiment, the seat frame mechanism is disposed on the upper side of the base bracket 101, and a drive mechanism 102 is disposed on the base bracket 101. The dual-head motor of the drive mechanism 102 is fixed on the horizontal plate, and the two ends of the dual-head motor are used in conjunction with the worm gear box that cooperates with the slide rail on the base bracket 101. The first support 103 and the second support 104 are fixed on the slide rail. The cooperation structure of the slide rail and the worm gear box can adopt the prior art, such as the structure disclosed in the prior art CN205033973U.

[0021] The first support 103 is disposed on the front side of the base bracket 101 and is symmetrically arranged. The second support 104 is disposed on the rear side of the base bracket 101 and is symmetrically arranged. The toothed bracket 105 is rotatably connected to the first support 103 and meshes with the gear on the drive motor of the power device 113. The auxiliary bracket 106 is rotatably connected to the first support 103 on the side away from the power device 113. The auxiliary bracket 106 is rotatably connected to the connecting piece 108. One end of the connecting piece 108 is fixedly disposed on the seat frame mechanism, and the other end is rotatably connected to the toothed bracket 105 and the auxiliary bracket 106. One end of the connecting arm 107 is rotatably connected to the second support 104, and the other end is welded to the seat frame mechanism. The power device 113 is installed on the first support 103 on the side away from the auxiliary bracket 106. After installation, its drive motor is at a 45° angle to the horizontal plane of the base bracket 101. The mounting shaft end of one side of the toothed bracket 105 is mounted on the first support 103 via a rotating bearing and meshes with the gear on the drive motor of the power device 113. The other side of the toothed bracket 105 is hinged to the connecting piece 108 on the side away from the auxiliary bracket 106 for transmission. One end of the auxiliary bracket 106 is hinged to the first support 103, and the other end is hinged to the connecting piece 108. One end of the connecting arm 107 is directly hinged to the first support 103 and the second support 104 respectively, and the other end is fixed to the seat frame mechanism. The power device 113 is used to drive the toothed bracket 105 to rotate, and its fixing seat is fixed by bolts. At the same time, after the power device 113 is installed, its drive motor is at a 45° angle to the horizontal plane of the base bracket 101. The purpose of this structure is to facilitate the setting of the foam assembly on the front side of the seat cushion.

[0022] Secondly, the seat frame 109 is disposed above the base support 101; the mating device is disposed on the seat frame 109. Sleeves are respectively provided on both sides of the seat frame 109, which facilitate welding and fixing of the connecting piece 108 and the connecting arm 107 after they are fitted together. The mating device is used for mating the seat cushion.

[0023] Then, the skeleton strip 110 is welded to the seat frame skeleton 109; the first skeleton plate 111 is welded to the skeleton strip 110. A plurality of the first skeleton plates 111 are welded and installed on the skeleton strip 110 for subsequent seat cushion setting support.

[0024] Furthermore, the second frame plate 112 is welded to the frame strip 110 and is located away from the first frame plate 111. The second frame plate 112 cooperates with the first frame plate 111 to provide support for the seat cushion.

[0025] Finally, the drive motor of the power unit 113 is equipped with a brake mechanism. The brake mechanism facilitates locking engagement when the shaft is stopped.

[0026] When using this utility model to solve the problem of the inability to adjust the tilt angle of existing zero-gravity seats, the user controls the power unit 113 via control buttons inside the vehicle. The drive motor of the power unit 113 drives the gear on its output side. The truncated gear meshes with the toothed bracket 105, causing the toothed bracket 105 to rotate. After the toothed bracket 105 rotates, it drives the connecting piece 108 to move. At the same time, the auxiliary bracket 106 moves, and the connecting arm 107 rotates in coordination, thereby lifting the seat frame mechanism. At this time, the tilt angle of the seat increases. Conversely, when the drive motor of the power unit 113 rotates in the opposite direction, it drives the seat frame mechanism to move downward, thereby reducing the tilt angle of the seat and completing the adjustment. This solves the problem of the inability to adjust the tilt angle of existing zero-gravity seats.
