Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a push-out seat footrest structure. Background Technology

[0002] Car seats are one of the key components of a car, but existing car seats have limited functions and do not have the function of purifying the air inside the car.

[0003] A search revealed that prior art CN215850648U discloses a car seat, including a seat body and a seat back. The seat back has a cavity, and one side has a perforation communicating with the cavity. The cavity houses a smoke purification device, a smoke absorption device, and a translation mechanism. The smoke purification device is located below the smoke absorption device and the translation mechanism, and is connected to the smoke purification device via a flexible hose. The smoke absorption device is connected to the translation mechanism via a rotating disk, and moves out of the perforation through the translation mechanism to absorb smoke. This utility model, through ingenious design, incorporates a smoke purification device, a smoke absorption device, and a translation mechanism within the seat back. The smoke absorption device moves out of the seat back via the translation mechanism to absorb smoke, thereby purifying the air inside the vehicle.

[0004] However, in actual use, the aforementioned car seats do not have a footrest structure near the bottom of the backrest, which means that passengers behind the seat can only place their feet on the floor mats inside the car, resulting in poor comfort. Utility Model Content

[0005] The purpose of this invention is to provide a push-out seat footrest structure, which aims to provide a support point for the feet of rear passengers during seat use, thereby reducing leg fatigue and improving riding comfort.

[0006] To achieve the above objectives, this utility model provides a push-out seat footrest structure, including a seat frame and a backrest frame. The backrest frame is disposed on the rear side of the seat frame and is covered with a foam component on the outside. It also includes an auxiliary mechanism.

[0007] The auxiliary mechanism includes a motor mounting plate, a drive motor, a pinion, a shaped gear block, a positioning block, a rotating tube, a mounting device, and an insertion device. The motor mounting plate is fixed to one side of the backrest frame. The drive motor is detachably connected to the motor mounting plate and located on one side of the motor mounting plate. The pinion is fixed to the output shaft of the drive motor. The shaped gear block meshes with the pinion and is located on one side of the pinion. The positioning block is fixedly connected to the backrest frame and symmetrically arranged. The rotating tube is fixedly connected to the shaped gear block and rotatably connected to the positioning block, and is located between the positioning blocks. The mounting device is located on the side of the shaped gear block away from the rotating tube. The insertion device is located on the top of the backrest frame.

[0008] The installation device includes a plastic part fixing plate and a support plate. The plastic part fixing plate is integrally formed with the irregular toothed block. The support plate is detachably connected to the plastic part fixing plate and is located on the plastic part fixing plate.

[0009] The insertion device includes a first mounting tube and a second mounting tube. The first mounting tube is disposed on one side of the top of the backrest frame, and the second mounting tube is disposed on the side of the backrest frame close to the first mounting tube.

[0010] The backrest frame is further provided with a reinforcing part, which is located between the backrest frame and the foam assembly.

[0011] The irregularly shaped toothed block is integrally provided with a stabilizing block.

[0012] This utility model discloses a push-out seat footrest structure. During seat use, the drive motor is controlled to rotate a small gear, which in turn drives a shaped gear block. The shaped gear block then rotates, causing the mounting device to flip downwards, thus pushing out the footrest. The occupant's feet can then be placed on the footrest for support. When not in use, the drive motor is controlled to rotate the small gear, which, in conjunction with the shaped gear block, causes the mounting device to rotate upwards for storage. This design provides a support point for the rear passengers' feet during seat use, reducing leg fatigue and improving seating comfort. Attached Figure Description
