Description

Technical Field

[0001] This utility model relates to the field of leg support technology, and in particular to an adjustable thigh support mechanism for automobile seats. Background Technology

[0002] As cars become commonplace in households, they have become necessities in people's daily lives, and people's demands for car comfort are increasing. Traditional car seats lack leg rests and cannot accommodate drivers and passengers of varying heights. Generally, to accommodate shorter drivers and passengers, the common practice is to design the seat to be relatively short. Therefore, for taller drivers and passengers, such seats obviously cannot meet their comfort requirements.

[0003] Currently, two types of car seats have emerged on the market: one with an adjustable seat length and the other with a leg rest. However, existing leg rests suffer from uneven adjustment due to the significant friction between the leg rest and the seat. Utility Model Content

[0004] The purpose of this utility model is to provide a thigh support adjustment mechanism for automobile seats, which aims to solve the problem that the adjustment of the thigh support is not smooth due to the large friction between the thigh support and the seat during the adjustment of the existing thigh support.

[0005] To achieve the above objectives, this utility model provides an automobile seat thigh support adjustment mechanism, including a base, a moving component, a thigh support body, two base frames, multiple rotating shafts, and multiple bearings;

[0006] The movable component is mounted on the base, the leg support body is mounted on the movable component, two base frames are respectively mounted on the base and are located between the base and the leg support body, multiple rotating shafts are respectively rotatably connected to the two base frames and are respectively located on the two base frames, and multiple bearings are respectively mounted on the multiple rotating shafts.

[0007] The base includes a seat body, a base plate, and two reinforcing ribs. The base plate is fixedly connected to the seat body and is located on the seat body. The two reinforcing ribs are fixedly connected to the base plate and are located at the bottom of the base plate.

[0008] The moving component includes a motor, a lead screw, a ball nut, and a mounting component. The motor is fixedly connected to the base plate and located at the bottom of the base plate. The lead screw is fixedly connected to the output end of the motor and located on one side of the motor. The ball nut is threadedly connected to the lead screw and located around the lead screw. The mounting component is installed on the ball nut.

[0009] The base frame has two limiting blocks, which are threadedly connected to the base frame and are both located on the base frame.

[0010] The mounting component includes a mounting plate and two fixing rods. The mounting plate is fixedly connected to the ball nut and is located on one side of the ball nut. The two fixing rods pass through the leg support body and are threadedly connected to the mounting plate.

[0011] This utility model discloses an adjustable thigh support mechanism for a car seat, comprising a base, a movable component, a thigh support body, two base frames, multiple rotating shafts, and multiple bearings. The movable component is mounted on the base, the thigh support body is mounted on the movable component, the two base frames are respectively mounted on the base and located between the base and the thigh support body, the multiple rotating shafts are rotatably connected to the two base frames and are respectively located on the two base frames, and the multiple bearings are respectively mounted on the multiple rotating shafts. The base provides mounting conditions for the moving component, the leg rest body, and the two base frames. The two base frames provide mounting conditions for the multiple rotating shafts, and the multiple rotating shafts provide mounting conditions for the multiple bearings. When the leg rest body needs to be adjusted, the drive component is activated. The drive component drives the leg rest body to move away from the base on the multiple bearings. The multiple bearings support the leg rest body, improving the stability of the leg rest body during movement and reducing the friction between it and the base. The adjustment of the leg rest body is completed when it moves to the preset position. This solves the problem of uneven leg rest adjustment caused by the large friction between the leg rest and the seat during existing leg rest adjustments. Attached Figure Description

[0021] In this embodiment, the base provides installation conditions for the moving component, the leg rest body 1, and the two base frames 2. The two base frames 2 provide installation conditions for the multiple rotating shafts 3, and the multiple rotating shafts 3 provide installation conditions for the multiple bearings 4. When it is necessary to adjust the leg rest body 1, the drive component is activated. The drive component drives the leg rest body 1 to move away from the base on the multiple bearings 4. The multiple bearings 4 support the leg rest body 1, improving the stability of the leg rest body 1 during movement and reducing the friction between it and the base. The adjustment of the leg rest body 1 is completed when the leg rest body 1 moves to the preset position. This solves the problem that the existing leg rests are not smooth to adjust due to the large friction between the leg rest and the seat.

[0022] Furthermore, the base includes a seat body 5, a base plate 6, and two reinforcing ribs 7. The base plate 6 is fixedly connected to the seat body 5 and is located on the seat body 5. The two reinforcing ribs 7 are respectively fixedly connected to the base plate 6 and are both located at the bottom of the base plate 6.

[0023] In this embodiment, the base 5 provides the mounting conditions for the base plate 6, and the base plate 6 provides the mounting conditions for the reinforcing rib 7 and the motor 8. The reinforcing rib 7 can improve the support strength of the base plate 6.

[0024] Furthermore, the moving component includes a motor 8, a lead screw 9, a ball nut 10, and a mounting component. The motor 8 is fixedly connected to the base plate 6 and located at the bottom of the base plate 6. The lead screw 9 is fixedly connected to the output end of the motor 8 and located on one side of the motor 8. The ball nut 10 is threadedly connected to the lead screw 9 and located around the lead screw 9. The mounting component is mounted on the ball nut 10.

[0025] In this embodiment, the operation of the motor 8 can drive the lead screw 9 to rotate forward or in reverse. The rotation of the lead screw 9 can drive the ball nut 10 to move. The movement of the ball nut 10 can drive the leg support body 1 to move. The leg support body 1 can be mounted on the ball nut 10 through the mounting component.

[0026] Furthermore, the base frame 2 has two limiting blocks 11, which are threadedly connected to the base frame 2 and are both located on the base frame 2.

The mounting plate 12 is fixedly connected to the ball nut 10 and is located on one side of the ball nut 10. The two fixing rods 13 pass through the leg support body 1 and are threadedly connected to the mounting plate 12 respectively.

[0029] In this embodiment, the mounting plate 12 provides installation conditions for the two fixing rods 13, and the leg support body 1 can be installed on the ball nut 10 through the two fixing rods 13.

[0030] When the leg rest body 1 needs to be adjusted, the motor 8 is started. The motor 8 drives the lead screw 9 to rotate. The lead screw 9 drives the ball nut 10 to move closer to the motor 8. The ball nut 10 drives the leg rest body 1 to move away from the base on the multiple bearings 4. The multiple bearings 4 support the leg rest body 1, improving the stability of the leg rest body 1 during movement and reducing the friction between it and the base. The adjustment of the leg rest body 1 is completed when the leg rest body 1 moves to the preset position. This solves the problem of the existing leg rests not adjusting smoothly due to the large friction between the leg rest and the seat.
