Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to a seat that is raised and lowered by a lead screw motor. Background Technology

[0002] With the development of the automotive industry, the requirements for car seats are becoming increasingly stringent, demanding higher levels of comfort, load-bearing capacity, manufacturing processes, and product quality. Traditional, simple adjustable seats can no longer meet the quality needs of modern driving and riding. Because different people have significantly different requirements for seating space, drivers and passengers need to adjust the seat according to their individual body shapes and needs.

[0003] Currently, existing car seats typically use dual motors for adjustment, which takes up a lot of space and increases the production cost of car seats. Utility Model Content

[0004] The purpose of this invention is to provide a seat that is raised and lowered by a lead screw motor, in order to solve the problem of high production costs of existing car seats.

[0005] To achieve the above objectives, this utility model provides a seat that is raised and lowered by a lead screw motor, including a base, a pad, and an adjustment mechanism. The adjustment mechanism includes a transmission rod one, a drive assembly, a transmission rod two, a moving cylinder, a moving assembly, and a driven assembly.

[0006] The first transmission rod is rotatably connected to the base and is located on the base. The driving assembly is mounted on the first transmission rod. The second transmission rod is mounted on the side of the driving assembly away from the first transmission rod. The moving cylinder is mounted on one side of the moving assembly. The driven assembly is mounted on the base and connected to the moving cylinder. The pad is mounted on the driven assembly, the moving assembly, and the second transmission rod.

[0007] The drive assembly includes a motor, a lead screw, and a sleeve. The motor is rotatably connected to the first transmission rod and the second transmission rod, and is located between the first and the second transmission rods. The lead screw is fixedly connected to the output end of the motor. The sleeve is threadedly connected to the lead screw and fixedly connected to the movable cylinder.

[0008] The adjustment mechanism further includes two vertical plates and two guide blocks. The two vertical plates are fixedly connected to the base and are located on the base. The two guide blocks are slidably connected to the two vertical plates and fixedly connected to the pad.

[0009] The moving component includes a third transmission rod and a fourth transmission rod. The third transmission rod is rotatably connected to the base and located on one side of the base. The fourth transmission rod is rotatably connected to the third transmission rod and is rotatably connected to the pad.

[0010] The driven component includes transmission rod five, transmission rod six, transmission rod seven, and transmission rod eight. Transmission rod five is rotatably connected to the base and is located on the base. Transmission rod six is ​​rotatably connected to transmission rod five and is rotatably connected to the pad. Transmission rod seven is rotatably connected to the base and is located on the base. Transmission rod eight is rotatably connected to transmission rod seven and is rotatably connected to the pad.

[0011] This invention discloses a seat that is raised and lowered by a lead screw motor. The base provides the installation conditions for the adjustment mechanism. When the height of the pad needs to be adjusted, the drive assembly is activated. The drive assembly drives the moving cylinder to move away from the drive assembly. The drive assembly drives the first transmission rod and the second transmission rod to rotate. The moving cylinder drives the moving assembly to move. The second transmission rod and the moving assembly drive the pad to rise away from the base. At the same time, the driven assembly moves to support the pad until the pad moves to the preset position, thus completing the height adjustment of the pad. Conversely, the pad body can be reset. This solves the problem of high production cost of existing car seats. Attached Figure Description

The adjustment mechanism 3 includes a transmission rod 4, a drive assembly 5, a transmission rod 6, a moving cylinder 7, a moving assembly 8 and a driven assembly 9.

[0019] The transmission rod 4 is rotatably connected to the base 1 and is located on the base 1. The drive assembly 5 is mounted on the transmission rod 4. The transmission rod 6 is mounted on the side of the drive assembly 5 away from the transmission rod 4. The moving cylinder 7 is mounted on one side of the moving assembly 8. The driven assembly 9 is mounted on the base 1 and connected to the moving cylinder 7. The pad 2 is mounted on the driven assembly 9, the moving assembly 8, and the transmission rod 6.

[0020] In this embodiment, the base 1 provides the installation conditions for the adjustment mechanism 3. When it is necessary to adjust the height of the pad 2, the drive assembly 5 is activated. The drive assembly 5 drives the moving cylinder 7 to move away from the drive assembly 5. The drive assembly 5 drives the transmission rod 4 and the transmission rod 6 to rotate. The moving cylinder 7 drives the moving assembly 8 to move. The transmission rod 6 and the moving assembly 8 drive the pad 2 to rise away from the base 1. At the same time, the driven assembly 9 moves to support the pad 2 until the pad 2 moves to the preset position, thus completing the height adjustment of the pad 2. Conversely, the pad 2 body can be reset, thereby solving the problem of high production cost of existing car seats.

[0021] Furthermore, the drive assembly 5 includes a motor 10, a lead screw 11, and a sleeve 12. The motor 10 is rotatably connected to the first transmission rod 4 and the second transmission rod 6, and is located between the first transmission rod 4 and the second transmission rod 6. The lead screw 11 is fixedly connected to the output end of the motor 10. The sleeve 12 is threadedly connected to the lead screw 11 and fixedly connected to the movable cylinder 7.

[0022] In this embodiment, the operation of the motor 10 can drive the lead screw 11 to rotate, the rotation of the lead screw 11 can drive the sleeve 12 to move, and the movement of the sleeve 12 can drive the moving cylinder 7 to move.

[0023] Furthermore, the adjustment mechanism 3 also includes two vertical plates 13 and two guide blocks 14. The two vertical plates 13 are fixedly connected to the base 1 and are located on the base 1.

[0025] Furthermore, the moving component 8 includes a third transmission rod 15 and a fourth transmission rod 16. The third transmission rod 15 is rotatably connected to the base 1 and is located on one side of the base 1. The fourth transmission rod 16 is rotatably connected to the third transmission rod 15 and is rotatably connected to the pad 2.

[0026] In this embodiment, when the pad 2 moves, it drives the transmission rod 3 15 and the transmission rod 4 16 to rotate. When the included angle between the transmission rod 3 15 and the transmission rod 4 16 increases, the pad 2 rises; conversely, the pad 2 lowers.

[0027] Furthermore, the driven assembly 9 includes transmission rod 5 17, transmission rod 6 18, transmission rod 7 19, and transmission rod 8 20. Transmission rod 5 17 is rotatably connected to the base 1 and is located on the base 1. Transmission rod 6 18 is rotatably connected to transmission rod 5 17 and is rotatably connected to the pad 2.
