Description
Technical Field
[0001] The utility model relates to the technical field of vehicle seats, and particularly relates to a seat leg rest integrated with a footrest. Background Art
[0002] A conventional leg rest can only support the thighs and calves of a passenger to a certain extent, with the soles and heels in a suspended state. To provide complete support for the legs and further improve comfort, a footrest function needs to be added. The known footrest flipping functions on the market are divided into two types: electric and manual, among which the electric footrest is more widely used. The existing electric footrests usually adopt gear drive. Due to problems such as gear backlash, the shaking of the footrest mechanism is relatively obvious. Moreover, the footrest drive mechanism cannot be hidden inside the footrest, resulting in poor integrity. Content of the Utility Model
[0003] Aiming at the problems existing in the above-mentioned prior art, the utility model aims to provide a seat leg rest integrated with a footrest to solve the problems of easy shaking and poor integrity of the existing footrest mechanism.
[0004] To achieve the above object, the utility model provides a seat leg rest integrated with a footrest, which includes a leg rest fixed plate and a leg rest extension plate. The leg rest extension plate is slidably arranged on the leg rest fixed plate, and a power device is arranged between the two. The power device can drive the leg rest extension plate to slide forward relative to the leg rest fixed plate to open. The front end of the leg rest extension plate is connected with a footrest assembly through a flipping mechanism. The footrest assembly is received above the leg rest extension plate, and the flipping mechanism can drive the footrest assembly to flip forward to open.
[0005] In the above solution: the power device includes a screw rod motor and a multi-link mechanism. The screw rod motor is fixed on the leg rest fixed plate, and a nut is threadedly sleeved on its screw rod. The multi-link mechanism is connected between the nut and the leg rest extension plate. A support frame is arranged at one end of the screw rod away from the motor, and the support frame is fixed on the leg rest extension plate. The screw rod is movably connected with the support frame. This device can realize the arbitrary elongation of the leg rest extension plate within a limited stroke. The screw rod motor can drive the screw rod to rotate, thereby driving the nut to move back and forth, and further driving the leg rest extension plate to move back and forth.
[0006] In the above solution: The multi-link mechanism includes a first link, a second link, a third link, a fourth link, a fifth link, and a sixth link. The front ends of the first link and the second link are hinged together and hinged and fixed to the leg rest fixing plate. The front end of the first link is hinged. The rear end of the second link is hinged to the front end of the fourth link. The middle parts of the third link and the fourth link are hinged together and hinged and fixed to the nut. The rear end of the third link is hinged to the front end of the fifth link. The rear end of the fourth link is hinged to the front end of the sixth link. The rear ends of the fifth link and the sixth link are hinged together and hinged and fixed to the leg rest extension plate. The multi-link mechanism has a simple structure and good stability.
[0007] In the above solution: The leg rest extension plate is slidably connected to the leg rest fixing plate through a drawer rail, with a simple structure and convenient storage.
[0008] In the above solution: The flipping mechanism includes two angle adjusters, a synchronizing rod connecting the two angle adjusters, and an angle adjuster motor installed on the synchronizing rod. The front ends of both sides of the footrest assembly are respectively connected to the leg rest extension plate through angle adjusters. The angle adjuster motor is fixed to the leg rest extension plate. The angle adjuster motor can drive the synchronizing rod to rotate, thereby driving the footrest assembly to flip, which is beneficial to realizing stepless adjustment of the footrest assembly, and has a simple structure and convenient operation.
[0009] In the above solution: The angle adjuster is an eccentric angle adjuster, which is convenient for connecting the leg rest extension plate and the footrest assembly.
[0010] In the above solution: The leg rest extension plate is covered with a leg rest housing. The leg rest housing is composed of a leg rest upper shielding member arranged above the leg rest extension plate and a leg rest lower shielding member arranged below the leg rest extension plate. The leg rest upper shielding member is fixed to the leg rest extension plate through self-tapping screws or snap fasteners. The leg rest lower shielding member is snap-fitted to the leg rest upper shielding member. The leg rest housing is provided with a through hole for the angle adjuster to pass through. The leg rest housing serves to cover up the ugliness and protect the leg rest extension plate.
[0011] In the above solution: The footrest assembly includes a footrest skeleton. The front ends of both sides of the footrest skeleton are provided with downwardly extending lugs. The angle adjuster is arranged on the corresponding side lugs. The footrest skeleton is covered with a footrest housing. The footrest housing is composed of a footrest upper shielding member arranged above the footrest skeleton and a footrest lower shielding member arranged below the footrest skeleton. The footrest lower shielding member is fixed to the footrest skeleton through self-tapping screws or snap fasteners. The footrest upper shielding member is snap-fitted to the footrest lower shielding member. The footrest housing is provided with a through hole for the angle adjuster to pass through. The provision of the lugs facilitates the installation of the angle adjuster. The footrest housing serves to cover up the ugliness and protect the footrest skeleton.
[0012] In the above solution: it further includes a cover plate that covers the top and both sides of the leg rest fixing plate. The leg rest fixing plate is fixed between the two side ends of the cover plate. After the leg rest extension plate and the footrest assembly are retracted, they can be hidden under the cover plate, and the cover plate plays a role in covering up defects and protecting.
[0013] The beneficial effects of the present utility model are:
[0014] By integrating the footrest mechanism and the leg rest mechanism, it is beneficial to simplify the structure, making the operation more convenient and the load capacity stronger; during use, only the power device is needed to open the leg rest extension plate, and the footrest is opened through the flipping mechanism, and the angle of the footrest can be adjusted according to the posture of the passenger. When not in use, the leg rest extension plate and the footrest can both be retracted onto the leg rest fixing plate, facilitating the space layout and having better integrity, greatly improving the comfort of the seat.
