Description
Technical Field
The utility model relates to a seat foot holds in palm elevation structure.
Background
Along with the brisk development of automobile industry, the automobile popularity is higher and higher, and people have higher and higher requirements for the comfort and the functionality of taking the seat in the trip process, and the seat that takes the leg to hold in the palm comes along with fortune, drives the in-process at a distance in particular, and the seat that takes the leg to hold in the palm can support passenger's shank, greatly reduces the tired sense of driving the member at a distance, improves the cost performance of this brand car when promoting the seat travelling comfort.
At present, leg supports in the market are controlled by a manual machine component and a motor screw rod, however, the manual machine component is controlled too hard, passengers experience a poor feeling, and the control cost of the motor screw rod is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a lifting structure of a seat foot support, aiming at the defects.
The utility model provides a scheme that technical problem adopted is, a seat foot holds in palm elevation structure, including leg layer board, air pocket, air pump, leg layer board rear side upper end articulates there is the connecting plate, the equal fixed mounting of connecting plate, air pump is on the seat skeleton body, and leg layer board rear side lower extreme articulates there is the lift adjustment pole, and the lift adjustment pole is including mutual articulated connecting rod A, connecting rod B, and connecting rod A lower extreme is articulated with the leg layer board, and connecting rod B upper end is articulated with the lift seat, and the air pocket is installed on the lift seat, and air pocket upper end connecting plate downside is connected.
Furthermore, the left side and the right side of the front end of the connecting plate are symmetrically provided with connecting lug parts hinged with the leg supporting plates.
Furthermore, the lifting adjusting rods are arranged in a bilateral symmetry mode, a rotating shaft is transversely arranged between the two lifting adjusting rods, and the end portions of the rotating shaft are hinged with the upper end of the connecting rod A and the lower end of the connecting rod B at the same side to form a composite hinge.
Compared with the prior art, the utility model discloses following beneficial effect has: simple structure, reasonable in design adopts pneumatic flexible arrangement, infinitely variable control, and the noise is little with low costs, safe and reliable.

Fig. 1 is a schematic structural view of the utility model;
in the figure: 1-a leg rest; 2-connecting plates; 3-connecting the ear; 4-air bag; 5, an air pump; 6-lifting seat; 7-connecting rod B; 8-Link A.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, a seat foot holds in palm elevation structure, including leg layer board, air pocket, air pump, leg layer board rear side upper end articulates there is the connecting plate, the equal fixed mounting of connecting plate, air pump is on the seat skeleton body, and leg layer board rear side lower extreme articulates there is the lift adjustment pole, and the lift adjustment pole includes mutual articulated connecting rod A, connecting rod B, and connecting rod A lower extreme is articulated with the leg layer board, and connecting rod B upper end is articulated with the lift seat, and the air pocket is installed on the lift seat, and air pocket upper end connecting plate downside is connected.
In this embodiment, the air bag is connected to the air pump through a pipeline, and the air pump controls inflation and deflation, or the output ends of the air bag and the air pump are connected to two ends of the three-way electromagnetic valve through pipelines, and the third end of the three-way electromagnetic valve is connected to the outside as an exhaust end.
In this embodiment, the left and right sides of the front end of the connecting plate are symmetrically provided with connecting lug parts hinged with the leg supporting plate.
In this embodiment, the lifting adjusting rods are arranged in bilateral symmetry, a rotating shaft is transversely arranged between the two lifting adjusting rods, and the end part of the rotating shaft is hinged with the upper end of a connecting rod A and the lower end of a connecting rod B at the same side to form a composite hinge.
When the lifting device is used, the air bag is inflated through the air pump to drive the air bag to extend, the lifting seat and the connecting plate are extruded through the air bag, and the lifting seat moves downwards so as to drive the leg supporting plate to swing upwards and lift through the lifting adjusting rod; the air pump is used for deflating the air bag, the pressure in the air bag is released, and the leg supporting plate is lowered and reset under the action of gravity.
The above-mentioned preferred embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned are only preferred embodiments of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included within the scope of the present invention.
