[0025] As Figures 1 to 7 shown, a leg rest adjustment mechanism of a vehicle seat includes a front support rod 1 of a seat frame. Symmetrically connected to the left and right sides of the front support rod 1 of the seat frame are side support plates 2. The lower side of the side support plate 2 is hinged to the upper end of the [description is incomplete here]. The lower end of the first connecting plate 3 is hinged to the lower end of the second connecting plate 4. The upper end of the second connecting plate 4 is hinged to the upper end of the third connecting plate 5. The middle of the third connecting plate 5 is hinged to the upper end of the fourth connecting plate 6. The lower end of the fourth connecting plate 6 is hinged to the lower end of the fifth connecting plate 7. The fifth connecting plate 7 and the second connecting plate 4 are hinged to form an X-shaped structure. The upper end of the fifth connecting plate 7 is hinged to the upper side of the side support plate 2. A first connecting rod 10 is fixedly connected to the fifth connecting plate 7. The first connecting rod 10 is fixedly connected to a driving device. The driving device is used to push the first connecting rod 10 in the direction of the front of the vehicle. A leg rest structure is connected to the third connecting plate 5.
[0026] In order to increase the support strength of the connection structure, a first fixing rod 20 is fixedly connected to the fourth connecting plate 6. Both ends of the first fixing rod 20 are fixedly connected to the side walls of the fourth connecting plates 6 on both sides to ensure the stability of the structure.
[0027] In order to facilitate the assembly of the leg rest housing so as not to affect the appearance of the seat, the leg rest structure includes a plurality of groups of mounting plates 30 fixedly connected to the third connecting plate 5. The mounting plates 30 are used to be fixedly connected to the leg rest housing by screwing.
[0028] In order to increase the support strength of the leg rest structure and ensure the stability of the connection, two groups of the mounting plates 30 are arranged in parallel at intervals. Two groups of second fixing rods 40 are fixedly connected to the mounting plates 30 in parallel at intervals. The second fixing rods 40 are perpendicular to the mounting plates 30. A groove can be provided at the rear side of the mounting plates 30, and the second fixing rods 40 are fixed in the grooves and connected by welding.
[0029] To facilitate the deployment and retraction of the leg rest structure, the pushing device includes a motor 8. The rotating shaft of the motor 8 drives a lead screw 801 to move in the front-rear direction of the vehicle body. The front end of the lead screw 801 is fixedly connected to a first connecting rod 10. The motor 8 can be provided by Anhui Shenghuabo Automotive Electric Appliance Co., Ltd., with the model ST22501. The motor 8 can be connected to a controller and control buttons to control the operation of the motor 8.
[0030] To facilitate the fixation of the lead screw 801 and the first connecting rod 10, the front end of the lead screw 801 is fixedly connected by screwing to a sixth connecting plate 802. The first connecting rod 10 passes through the sixth connecting plate 802 and is fixedly connected to the sixth connecting plate 802.
[0031] To better fix the leg rest adjusting mechanism on the seat frame, fixing plates 50 are symmetrically and fixedly connected to the left and right sides of the front support rod 1 of the seat frame by welding. The fixing plates 50 are fixedly connected to the side support plates 2. The fixing plates 50 are designed in a structure similar to the letter 'M' to increase the structural stiffness.
[0032] To facilitate the fixation with the fixing plate 50, a fixing edge 201 is bent at the upper end of the side support plate 2. The fixing edge 201 is fixedly connected to the fixing plate 50 by screwing.
[0033] To increase the strength and stability of the connection structure and facilitate the installation of the motor 8, third fixing rods 60 and fourth fixing rods 70 are also fixedly connected to both sides of the side support plate 2. The motor 8 can be fixedly welded to the third fixing rods 60 and fourth fixing rods 70 through a motor bracket 80.
[0034] This embodiment also provides a vehicle, which is provided with the above-mentioned automotive seat leg rest adjusting mechanism.
[0035] The principle of the present utility model:
[0036] When it is necessary to deploy the leg rest, the motor 8 is started by pressing the deployment button. The rotating shaft of the motor 8 drives the lead screw 801 and the sixth connecting plate 802 to move towards the front of the vehicle. Thus, the sixth connecting plate 802 pushes the first connecting rod 10 forward, and through the linkage of the first connecting plate 3, the second connecting plate 4, the third connecting plate 5, the fourth connecting plate 6, and the fifth connecting plate 7, the leg rest adjusting mechanism is fully deployed and rotated to the limit angle position. When it is necessary to retract the leg rest, the motor 8 is started by pressing the retraction button, and the reverse movement of the leg rest adjusting mechanism can be controlled to retract the leg rest.
[0037] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "bottom", "inner", "outer", "one end", "one side", "both ends", "both sides", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0038] The present utility model has been described exemplarily above in conjunction with the drawings. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present utility model, or directly applied to other occasions, they all fall within the protection scope of the present utility model.
