Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat adjustment, in particular to a leg rest mechanism with adjustable width. Background Technique

[0002] With the general improvement of people's requirements for the comfort of the sitting posture of seats, the support width of the existing seat leg rests is difficult to meet the needs of all passengers. At the same time, limited by the size of the seats in the vehicle, the support width of the leg rests is severely restricted. The utility model discloses a technology for adjusting the calf support width according to different human body characteristics. This technology meets the needs of people with different body postures to achieve a comfortable posture on the seat leg rest by adjusting the width extension of the leg rest, thereby alleviating the fatigue caused by long-term sitting.

[0003] In the prior art, most of the leg rest skeletons only provide a comfortable support width, which is difficult to meet the comfort requirements of most passengers. Simply widening the support surface of the leg rest will affect the aesthetics of the seat. Therefore, the current market mostly adopts a compromise solution, that is, sacrificing part of the leg rest width and aesthetics. This patent provides a new solution that can ensure the leg rest width without affecting the aesthetics. Content of the Utility Model

The deployment motor is assembled with the leg rest skeleton assembly by rivets. The width adjustment motor is assembled with the telescopic link assembly and the support plate by screws. The telescopic link assembly is assembled and connected with the leg rest skeleton assembly through the plastic guide sleeve.

[0006] Preferably, the leg rest skeleton assembly includes a support link riveting assembly. The number of the support link riveting assemblies is two and they are symmetrically arranged. A motor fixing seat sub-assembly, a drive reinforcement tube assembly, a reinforcement tube, and a fixing seat are successively fixed between the two support link riveting assemblies from left to right.

[0007] Preferably, the support link riveting assembly includes a link base, a first link, a rivet, a support plate fixing seat, an insertion tube fixing seat, a second link, a third link, and a fourth link. The support plate fixing seat and the insertion tube fixing seat are welded and assembled. The link base is connected to the first link and the fourth link by rivets. The second link is connected to the first link and the support plate fixing seat by rivets.

[0008] Preferably, the motor fixing seat sub-assembly includes a motor fixing seat and a connecting rod base reinforcing pipe, and the motor fixing seat and the connecting rod base reinforcing pipe are welded and assembled.

[0028] The present utility model provides a leg rest mechanism with adjustable width, including a leg rest skeleton, as Figure 1 shown. The leg rest skeleton includes a leg rest skeleton assembly 1, a deployment motor 2, a telescopic link assembly 3, a support plate 4, a width adjustment motor 5, and a plastic guide sleeve 6. The deployment motor 2 is assembled with the leg rest skeleton assembly 1 through a rivet 1013, and the width adjustment motor 5 is assembled with the telescopic link assembly 3 and the support plate 4 through screws. The three-dimensional view of the support plate 4 is as Figure 8 shown, and the three-dimensional view of the width adjustment motor 5 is as Figure 9 shown.

[0029] The telescopic link assembly 3 is assembled and connected with the leg rest skeleton assembly 1 through the plastic guide sleeve 6. The three-dimensional view of the deployment motor 2 is as Figure 6 shown. The adjustment of the deployment angle of the leg rest is realized through the deployment motor 2, and the adjustment of the support width of the leg rest is realized through the width adjustment motor 5 and the telescopic link assembly 3.

[0030] As Figure 2 shown, the leg rest skeleton assembly 1 includes a support link riveting assembly 101. The number of the support link riveting assemblies 101 is two and they are symmetrically arranged. Between the two support link riveting assemblies 101, a motor fixing seat sub-assembly 102, a driving reinforcement tube assembly 103, a reinforcement tube 105, and a fixing seat 104 are successively fixed from left to right.

[0031] As Figure 3As shown in the figure, the support link riveting assembly 101 includes a link base 1011, a first link 1012, a rivet 1013, a support plate fixing seat 1014, an insertion tube fixing seat 1015, a second link 1016, a third link 1017, and a fourth link 1018. The support plate fixing seat 1014 and the insertion tube fixing seat 1015 are welded and assembled, and the link base 1011 is connected to the first link 1012 and the fourth link 1018 by the rivet 1013. The second link 1016 is connected to the first link 1012 and the support plate fixing seat 1014 by the rivet 1013.

[0032] As Figure 4 shown in the figure, the motor fixing seat sub-assembly 102 includes a motor fixing seat 1021 and a link base reinforcing tube 1022. The motor fixing seat 1021 and the link base reinforcing tube 1022 are welded and assembled.

[0033] As Figure 5 shown in the figure, the drive reinforcing tube 103 includes a welding nut 1031, a drive connecting piece 1032, and a drive reinforcing tube 1033. The welding nut 1031 and the drive connecting piece 1032 are welded and assembled, and the drive connecting piece 1032 and the drive reinforcing tube 1033 are welded and assembled.

[0034] As Figure 7 shown in the figure, the telescopic link assembly 3 includes a side support plate 301. A reinforcing piece 305 is welded on the side support plate 301. The reinforcing piece 305 and the guide rod 304 are welded and assembled. The guide rod 304 is locked and assembled with the linkage piece 303 by a screw 302.

[0035] The working principle of this solution is as follows: The motor fixing seat 1021 in the leg rest frame assembly 1 is connected to the deployment motor 2 by the rivet 1013. At the same time, the deployment motor 2 is connected to the drive connecting piece 1032 by the rivet 1013. When the deployment motor 2 works, the first link 1012, the second link 1016, the third link 1017, and the fourth link 1018 in the support link riveting assembly 101 move, realizing the upward rotation and deployment of the support plate 4.

[0036] The width adjustment motor 5 is assembled with the telescopic link assembly 3 and the support plate 4 by screws. The guide rod 304 is assembled with the leg rest frame assembly 1 and the plastic guide sleeve 6. When the width adjustment motor 5 works, the guide rods on both sides of the leg rest slide along the plastic guide sleeve 6, thereby realizing the extension and retraction of the side support plate 301 and adjusting the width of the leg rest support surface.

[0037] As Figure 10 shown in the figure, it is a schematic diagram of the leg rest frame in different states. The deployment and storage of the leg rest frame are combined with the extension and retraction functions of the side support plate 301, allowing people with different body signs to achieve a comfortable posture for the calves on the seat, thereby alleviating the fatigue caused by long-term sitting.
