Description

Technical Field

[0001] This utility model belongs to the field of automotive seat leg rest technology, specifically relating to an automotive seat leg rest with a shielding structure. Background Technology

[0002] To enhance passenger comfort, some car seats are equipped with retractable leg rests at the front to support the passenger's lower legs. When not in use, the leg rest can be folded back to the front of the seat; when needed, it can be extended from the front of the seat.

[0003] However, in existing car seat leg rests, the sides of the leg rest assembly are not covered. When the leg rest is unfolded, passengers can see the internal structure of the leg rest from the side, which affects the aesthetics of the seat. Moreover, without side coverings, passengers can directly touch the internal structure of the leg rest, which can easily lead to safety hazards. Therefore, a car seat leg rest with a covering structure is designed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a car seat leg support mechanism with a concealed internal structure.

[0005] The technical solution of this utility model is as follows:

[0006] A car seat leg rest with a shielding structure includes two frames, a connecting column fixed between the two frames, a mounting bracket fixed to the front side of the rear frame, a lead screw motor fixed to the front side of the mounting bracket, a connecting piece hinged to the output end of the lead screw motor, the connecting piece fixed to a connecting rod assembly, the front and rear ends of the connecting rod assembly respectively hinged to the right ends of the two frames, a leg rest plate hinged to the upper right end of the connecting rod assembly, shielding components rotatably connected to both the front and rear sides of the connecting rod assembly, the right ends of the two shielding components being mounted on the inner wall of the leg rest plate via guide components, a support component being mounted on the lower part of the leg rest plate, and the lower right parts of the two shielding components being rotatably connected to the support component.

[0007] Furthermore, the linkage assembly includes two first linkages respectively hinged to the upper right ends of the two frames, a third linkage hinged to the right end of each of the two first linkages, the right ends of the two third linkages respectively hinged to the front and rear parts of the leg support plate, a fourth linkage hinged to the middle of each of the two first linkages, the right ends of the two fourth linkages respectively hinged to the front and rear parts of the leg support plate, the left ends of the two fourth linkages respectively hinged to the right ends of the two second linkages, the left ends of the two second linkages respectively hinged to the lower right parts of the two frames, and the two first linkages are fixedly connected by a connecting rod, with the connecting piece fixed to the middle of the connecting rod.

[0008] Furthermore, the leg support plate includes a top plate, and side plates are fixed on both the front and rear sides of the top plate. The guide assembly is disposed on the side plates. Two connecting brackets are fixed to the bottom of the top plate by bolts. The third link and the fourth link are respectively hinged to the lower part of the top plate through the two connecting brackets. The support assembly is installed on the inner wall of the side plates.

[0009] Furthermore, the shielding assembly includes a first shielding plate fixed to the side of the first connecting rod away from the lead screw motor, a lower shielding plate fixed to the right side of the two first shielding plates, a connecting column rotatably connected to the side of the two first shielding plates away from the first connecting rod, a second shielding plate fixed to the two connecting columns, the upper right part of the two second shielding plates rotatably connected to the guide assembly, and the lower right part of the two second shielding plates rotatably connected to the support assembly.

[0010] Furthermore, the guide assembly includes two guide channels fixed to the inner walls of the two side plates, and guide wheels are slidably arranged in both guide channels. The two guide wheels are respectively rotatably connected to the upper right part of the two second baffles.

[0011] Furthermore, the support assembly includes two support wheels respectively fixed to the lower right part of the two second baffles. The two support wheels slide on two sets of support plates respectively. The two sets of support plates are respectively fixed on the inner sidewalls of the two side plates. Each support plate includes a curved plate and a V-shaped plate. The support wheels can slide on the upper side of the curved plate and the V-shaped plate. Both the curved plate and the V-shaped plate are fixed on the inner sidewalls of the side plates.

[0012] Furthermore, the side plate is located on the side of the second cover plate away from the lead screw motor.

[0013] Furthermore, a stop block is fixed to the upper part of the second link.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model provides shielding components on both sides of the leg support assembly. The shielding components and guide components can work together with the leg support plate to effectively shield the internal structure of the leg support. Moreover, through the linkage between the shielding components and the leg support assembly and the leg support plate, as well as the cooperation of the guide components, the shielding components can move synchronously during the movement of the leg support assembly. This ensures that the internal structure of the leg support is shielded during the unfolding and retraction of the leg support, resulting in a high overall aesthetic appeal. Furthermore, the shielding components are located on the side wall of the leg support assembly, occupying little space and having a simple structure.

[0016] This invention provides a support component that can support the shielding component during its movement, and can also support the shielding component when it has moved to its maximum distance, thus preventing the shielding component from detaching from the guide component.

[0017] In summary, this utility model has the advantage of concealing the internal structure of the leg rest. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 2 As shown, a car seat leg rest with a shielding structure includes two frames 1, a connecting column 2 fixed between the two frames 1, a mounting bracket 3 fixed to the front side of the rear frame 1, a lead screw motor 4 fixed to the front side of the mounting bracket 3, a connecting piece 5 hinged to the output end of the lead screw motor 4, the connecting piece 5 fixed to the connecting rod assembly, the front and rear ends of the connecting rod assembly respectively hinged to the right ends of the two frames 1, a leg rest plate hinged to the upper right end of the connecting rod assembly, shielding components rotatably connected to both the front and rear sides of the connecting rod assembly, the right ends of the two shielding components are installed on the inner wall of the leg rest plate through guide components, a support component is installed at the lower part of the leg rest plate, and the lower right parts of the two shielding components are rotatably connected to the support component;

[0023] The connecting plate 5 is moved by the lead screw motor 4, which in turn drives the connecting rod assembly to unfold. The connecting rod assembly moves while simultaneously driving the shielding assembly. The shielding assembly, through the cooperation of the guide assembly and the support assembly, unfolds and closes along with the connecting rod assembly. The shielding assembly protects the connecting rod assembly throughout its movement, shielding the inside of the leg rest and preventing passengers from inserting their hands inside, thus avoiding injury. It also enhances the overall aesthetics of the leg rest and prevents passengers from seeing its internal structure.

[0024] In this embodiment, the linkage assembly includes two first linkages 6 respectively hinged to the upper right end of the two frames 1. The right end of each of the two first linkages 6 is hinged to a third linkage 8. The right end of each of the two third linkages 8 is hinged to the front and rear parts of the leg support plate. The middle part of each of the two first linkages 6 is hinged to a fourth linkage 9. The right end of each of the two fourth linkages 9 is hinged to the front and rear parts of the leg support plate. The left end of each of the two fourth linkages 9 is hinged to the right end of each of the two second linkages 7. The left end of each of the two second linkages 7 is hinged to the lower right part of the two frames 1. The two first linkages 6 are fixedly connected by a connecting rod 10. The connecting piece 5 is fixed in the middle of the connecting rod 10.

[0025] The screw motor 4 drives the connecting plate 5 to move, the connecting plate 5 drives the connecting rod 10 to move, the connecting rod 10 drives the two first connecting rods 6 to rotate around the axis connected to the frame 1, the rotation of the two first connecting rods 6 drives the two third connecting rods 8 to rotate, the rotation of the two first connecting rods 6 drives the two fourth connecting rods 9 to rotate, the two fourth connecting rods 9 drive the two second connecting rods 7 to rotate around the axis connected to the frame 1, the third connecting rods 8 and the fourth connecting rods 9 rotate at the same time, driving the leg support plate to unfold;

[0026] Similarly, the extension and retraction of the leg support plate are controlled by controlling the forward and reverse rotation of the lead screw motor 4.

[0027] Preferably, the leg support plate includes a top plate 11, with side plates 12 fixed on both the front and rear sides of the top plate 11. The shielding component is slidably disposed on the side plates 12. Two connecting brackets 21 are fixed to the bottom of the top plate 11 by bolts. The third connecting rod 8 and the fourth connecting rod 9 are respectively hinged to the lower part of the top plate 11 through the two connecting brackets 21. The support component is installed on the inner wall of the side plate 12.

[0028] Multiple reinforcing plates are fixed to the upper part of both the front and rear sides of the side plate 12. The multiple reinforcing plates are arranged at equal intervals to enhance the strength of the top plate 11.

[0029] In this embodiment, the shielding assembly includes a first shielding plate 13 fixed to the side of the first connecting rod 6 away from the lead screw motor 4, a lower shielding plate 19 fixed to the right side of the two first shielding plates 13, a connecting post 16 rotatably connected to the side of the two first shielding plates 13 away from the first connecting rod 6, a second shielding plate 15 fixed to the two connecting posts 16, the upper right part of the two second shielding plates 15 rotatably connected to the guide assembly, and the lower right part of the two second shielding plates 15 rotatably connected to the support assembly.

[0030] In this embodiment, the guide assembly includes two guide channels 17 fixed on the inner walls of the two side plates 12, and guide wheels 18 are slidably disposed in the two guide channels 17. The two guide wheels 18 are respectively rotatably connected to the upper right part of the two second baffles 15.

[0031] In this embodiment, the support assembly includes two support wheels 22 fixed to the lower right part of the two second cover plates 15 respectively. The two support wheels 22 slide on the two sets of support plates respectively. The two sets of support plates are fixed on the inner sidewalls of the two side plates 12 respectively. The support plate includes a curved plate 23 and a V-shaped plate 24. The support wheels 22 can slide on the upper side of the curved plate 23 and the V-shaped plate 24. The curved plate 23 and the V-shaped plate 24 are both fixed on the inner sidewalls of the side plates 12.

[0032] When the first link 6 rotates, it drives the first cover plate 13 to rotate. The first cover plate 13 will cause the second cover plate 15 to rotate. While the second cover plate 15 moves with the first cover plate 13, it will move in the guide channel 17 through the guide wheel 18, thereby controlling the movement trajectory of the second cover plate 15. At the same time, it will also move on the curved plate 23 and the V-shaped plate 24 through the support wheel 22. The curved plate 23 and the V-shaped plate 24 support the support wheel 22, thereby supporting the second cover plate 15. When the guide wheel 18 moves to the farthest distance in the guide channel 17, it continues to move to the right, thereby disengaging from the guide channel 17. At this time, the support wheel 22 is located on the V-shaped plate 24. The V-shaped plate 24 will support the support wheel 22 to prevent the guide wheel 18 from being unable to return to the guide channel 17. Moreover, at this time, the support wheel 22 is located on the inclined surface of the V-shaped plate 24 and will slide towards the middle of the V-shaped plate 24, which can help the guide wheel 18 return to the guide channel 17.

[0033] The first cover plate 13 is fixed to the side wall of the first connecting rod 6. The second cover plate 15, through linkage with the first cover plate 13 and the side plate 12, can always be located between the side plate 12 and the first cover plate 13, occupying little space and saving space.

[0034] Similarly, during the retraction of the first link 6, the first cover plate 13 will drive the second cover plate 15 to return along the track between the two guide channels 17. The first cover plate 13 can continuously block the first link 6 and part of the second link 7. The second cover plate 15, together with the side plate 12, can block the third link 8, the fourth link 9 and part of the second link 7, and can block the link assembly. It can also block the link assembly during the unfolding and retraction of the link assembly.

[0035] Both the guide wheel 18 and the support wheel 22 are circular, which allows them to move better on the guide channel 17, the curved plate 23 and the V-shaped plate 24, and reduces friction.

[0036] The width of the guide channel 17 is greater than the diameter of the guide wheel 18 to prevent the guide wheel 18 from being unable to move the upper or lower side wall of the guide channel 17.

[0037] The upper part of the upper guide plate is fixedly connected to the reinforcing plate. The channel formed by the two guide plates gradually widens from left to right. Through the movement track formed by the two guide plates, the second cover plate 15 can always cooperate with the side plate 12 and the first cover plate 13 to cover the internal structure of the leg support during the movement, thereby preventing the internal structure of the leg support from being exposed.

[0038] In this embodiment, the side plate 12 is located on the side of the second cover plate 15 away from the lead screw motor 4.

[0039] In this embodiment, a stop block 20 is fixed to the upper part of the second connecting rod 7;

[0040] When the linkage assembly is fully extended, the stop block 20 presses against the right end of the frame 1, thereby limiting the maximum distance of the linkage assembly's extension movement.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
