Description

Technical Field

[0001] The utility model relates to the field of automobile seat leg supports, in particular to an electric adjustable leg support for an automobile seat. Background Art

[0002] With the rise of new energy vehicles, the demand for chassis space for battery packs has further increased, resulting in a gradual reduction in the distance between the bottom of the seat and the car floor. Leg rests are installed under the co-pilot and rear seats of some cars to lift and support the legs of passengers, allowing passengers to relax and rest their legs during the ride. Leg rests in the prior art are stored under the seat when not in use, and their length usually cannot exceed the distance from the bottom of the seat to the car floor. Due to the close distance between the two, the leg rest is short in length, and the leg support effect on passengers is poor. Summary of the invention

[0003] The utility model aims at the deficiencies of the prior art and develops an electrically adjustable leg rest for a car seat. The technical solution adopted by the utility model is: an electrically adjustable leg rest for a car seat, characterized in that it comprises a right bracket 1, a left bracket 2, a right connecting rod mechanism 3, a leg rest 4, a telescopic mechanism 5, a push rod assembly 16 and a left connecting rod mechanism 20; the right connecting rod mechanism 3 comprises a first connecting rod 11 and a second connecting rod 12; the left connecting rod mechanism 20 comprises a third connecting rod 21 and a fourth connecting rod 22; the two ends of the first connecting rod 11 and the second connecting rod 12 are respectively hinged to the right bracket 1 and the leg rest 4; the two ends of the third connecting rod 21 and the fourth connecting rod 22 are respectively hinged to the left bracket 2 and the leg rest 4; the right connecting rod mechanism 3 is hinged to the left connecting rod mechanism 20 through a cross bar 13; the telescopic mechanism 5 is hinged to the leg rest 4, and comprises a cover plate 6, a telescopic plate 7, a slider 8, a threaded rod 9, a slide rail 10 and a first motor 15; the first motor 15 is fixedly arranged at the lower part of the cover plate 6 and is fixedly connected to the threaded rod 9; the slide rail 10 is fixedly connected to the cover plate 6; the slider 8 is fixedly connected to the telescopic plate 7; the telescopic plate 7 is slidably connected to the slide rail 10; the slider 8 is threadedly connected to the threaded rod 9; the push rod assembly 16 includes a second motor 17, a base 18 and a push rod 19; the second motor 17 is hinged to the base 18; the second motor 17 is connected to the push rod 19; the upper end of the push rod 19 is hinged to the cross bar 13; the switch 14 is fixedly arranged on the right bracket 1 and is placed above the first connecting rod 11; the switch 14 is electrically connected to the first motor 15.

[0004] The benefits of the utility model are as follows: 1. Since the telescopic mechanism is hinged at the outer end of the leg rest, when the leg rest rotates to the highest point, the telescopic plate of the telescopic mechanism can be extended, thereby extending the length of the support for the passenger's legs and achieving a better supporting effect; 2. Since the switch is fixedly arranged on the right bracket, the switch can only be closed when the leg rest rotates to the highest point, thereby effectively preventing the passenger from accidentally operating the telescopic plate to extend and damaging the car floor or the leg rest itself.

DETAILED DESCRIPTION

[0013] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] like Figures 1 to 3As shown, the utility model is an electric adjustable leg support for a car seat, comprising: a right bracket 1, a left bracket 2, a right connecting rod mechanism 3, a leg support 4, a telescopic mechanism 5, a push rod assembly 16 and a left connecting rod mechanism 20; the right connecting rod mechanism 3 comprises a first connecting rod 11 and a second connecting rod 12; the left connecting rod mechanism 20 comprises a third connecting rod 21 and a fourth connecting rod 22; the two ends of the first connecting rod 11 and the second connecting rod 12 are respectively hinged to the right bracket 1 and the leg support 4; the two ends of the third connecting rod 21 and the fourth connecting rod 22 are respectively hinged to the left bracket 2 and the leg support 4; the right connecting rod mechanism 3 is hinged to the left connecting rod mechanism 20 through a cross bar 13; the telescopic mechanism 5 is hinged to the leg support 4, and comprises a cover plate 6, a telescopic plate 7, a slider 8, a threaded rod 9, a slide rail 10 and a first Motor 15; the first motor 15 is fixedly arranged at the lower part of the cover plate 6 and is fixedly connected to the threaded rod 9; the slide rail 10 is fixedly connected to the cover plate 6; the slider 8 is fixedly connected to the telescopic plate 7; the telescopic plate 7 is slidably connected to the slide rail 10; the slider 8 is threadedly connected to the threaded rod 9; the push rod assembly 16 includes a second motor 17, a base 18 and a push rod 19; the second motor 17 is hinged to the base 18; the second motor 17 is connected to the push rod 19; the upper end of the push rod 19 is hinged to the cross bar 13; the switch 14 is fixedly arranged on the right bracket 1 and is placed above the first connecting rod 11; the switch 14 is electrically connected to the first motor 15.

[0015] like Figure 4 As shown, the right bracket 1 and the left bracket 2 of the utility model are respectively fixedly connected to the seat 28, and the utility model is in the retracted state in the figure. The control panel 23 for controlling the operation of the utility model is respectively provided with a lifting button 24, a retracting button 25, an extending button 26 and a lowering button 27, which respectively control the movement of the corresponding leg rest and the telescopic plate. The switch 14 in the figure is in the disconnected state. At this time, if the passenger presses the extending button 26 by mistake, the first motor 15 cannot work because the switch 14 is disconnected, which effectively prevents the passenger from accidentally operating the telescopic plate 7 without lifting the leg rest 4 and damaging the floor 29 or the utility model itself.

[0016] like Figure 5 As shown, when the passenger needs to use the leg rest, he only needs to press the lifting button 24. At this time, the second motor 17 rotates, causing the push rod 19 to move to the upper right in the figure. The push rod 19 pushes the cross bar 13 upward to raise the leg rest 4. When the leg rest 4 rises to the highest point, the first connecting rod 11 touches the switch 14, and the first motor 15 is turned on.

[0017] like Figure 3 and Figure 6As shown, when the passenger needs to further extend the leg support, he only needs to press the extension button 26, and the first motor 15 drives the threaded rod 9 to rotate, so that the slider 8 drives the telescopic plate 7 to move along the slide rail 10 to the right side in the figure, so as to increase the length of the passenger's leg support and obtain a better support experience.

[0018] like Figure 4 and Figure 5 As shown, when the passenger wants to retract the leg rest 4 and the telescopic plate 7, the correct operating steps are: first press the retraction button 25, the first motor 15 drives the threaded rod 9 to rotate in the opposite direction, and the telescopic plate 7 is retracted, and then press the descending button 27, the second motor 17 rotates in the opposite direction, the push rod 19 is retracted, and the leg rest 4 descends to the retracted state.

[0019] like Figure 7 As shown, when the passenger fails to retract the operation correctly, that is, directly presses the retraction button 25 without retracting the telescopic plate 7 first, the leg rest 4 drives the unretracted telescopic plate 7 to descend. When the telescopic plate 7 touches the floor 29, since it is hinged to the leg rest 4, the leg rest 4 continues to descend, and the telescopic plate 7 can rotate without damaging the floor 29 or causing damage to the parts of the utility model.

[0020] The passenger who made a mistake in the operation only needs to press the lifting button 24. When the leg rest 4 is lifted to the highest point and the switch 14 is turned on, the retractable plate 7 and the leg rest 4 can be retracted in sequence according to the above-mentioned correct operation.

[0021] The telescopic mechanism 5 used in the present invention is a commercially available product; the forward and reverse rotation control of the first motor 15 and the second motor 17 is also well known to those skilled in the art.

[0022] The utility model can be installed at the lower part of the co-pilot seat and the rear seat.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
