Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a seat widening support 100 for a vehicle, in this embodiment, taking the example of installing the seat widening support 100 on a vehicle frame 1 as an example, the seat widening support 100 includes a connecting plate 2, a slide rail 3, a widening support 4, a supporting arm 5, and a driving motor 6.

The frame 1 is intended to form a support structure. Specifically, the frame 1 is provided with two sliding grooves 11, and the two sliding grooves 11 are respectively located on two opposite sides of the frame 1 and extend in parallel along the long axis direction of the frame.

The connecting plates 2 include at least two, and the two connecting plates 2 are respectively parallel to the two sliding grooves 11 and are respectively clamped with the two sliding grooves 11, for example, clamped in the sliding grooves 11 through bolts.

The slide rail 3 comprises two parts and is respectively fixed on the top surfaces of the two connecting plates 2, namely one side far away from the frame 1.

each slide rail 3 comprises a rail 31 fixed on the top surface of the connecting plate 2 for filling a light and a rail shaft 32 clamped in the rail 31 and sliding along the axial direction of the rail 31 for filling a light and moving the end. Namely, the slide rail 3 is of a sliding pair structure.

The widening bracket 4 is covered on the slide rail 3 and fixed with the two rail shafts 32. The structural arrangement enables the widened support 4 to slide along the slide rail 31 along with the rail shaft 32 and simultaneously slide along the sliding groove 11 along with the connecting plate 2, so that two-stage sliding stroke adjustment is realized, and the adjusting stroke range of the widened support 4 is effectively enlarged.

Preferably, the widening support 4 further includes a mounting opening 41 penetrating therethrough for passing a wire, so that the electrically controlled wire harness is not interfered with the slide rail 3. Of course, the mounting opening 41 can also be used for mounting an aircraft seat.

In this embodiment, specifically, the widening bracket 4 includes a main body 42, two extending walls 43 respectively extending from two opposite sides of the main body 42 in a downward bending manner, and a mounting wall 44 respectively extending from two extending walls 43 in an outward bending manner. The body 42 is parallel to the frame 1 and spaced from each other, the two extending walls 43 are respectively bent and extended from two opposite sides of the body 42 to a direction close to the frame 1, and the two mounting walls 44 are respectively bent and extended from the two extending walls 43. The mounting port 41 is opened in the body 42, and the body 42 is fixed to the two rail shafts 32.

The supporting arm 5 is used for supporting and fixing the seat, and the supporting arm 5 comprises at least two supporting arms which are respectively fixed on two opposite sides of the widened support 4. When the seat is arranged behind the supporting arm 5, the two-stage adjustment stroke of the seat is realized, the front-back adjustment range is wider, and the comfort degree of people with different heights during riding is met.

Specifically, the support arms 5 are respectively fixedly mounted on the two mounting walls 44, and the two slide rails 3 are located inside the two extension walls 43. I.e. the height of said body 42 relative to the frame 1 is increased by the extension wall 43.

Preferably, one of the mounting walls 44 has a width greater than a width of the other mounting wall 44. When the widening bracket 100 is mounted on the vehicle frame 1, the mounting wall 44 with a small width is close to the window, and the other side is close to the aisle, so that the structure effectively releases the space, the width of the aisle is effectively increased, and the space is fully utilized to improve the riding comfort.

In this embodiment, the number of the support arms 5 is four, and each two support arms 5 are a group and are respectively mounted on the two mounting walls 44 to form symmetry, so that the stability is higher.

The driving motor 6 is fixed to the widened bracket 4 and located at the front end of the widened bracket 4, and specifically, the driving motor 6 is fixed to the body 42. The output shaft of the driving motor 6 is connected to the rail shaft 32 to drive the rail shaft 32 to slide along the rail 31, so that electric automatic adjustment is realized, and the adjustment is more stable.

Compared with the prior art, the widened support for the vehicle seat changes the space design of the original vehicle in future, the bottom plate is provided with two parallel chutes, the connecting plate slides back and forth along the two chutes respectively, on the basis, the slide rail fixed on the connecting plate and the widened support fixed on the slide rail are additionally arranged, the driving motor drives the rail shaft of the slide rail to slide along the slide way of the slide rail, so as to drive the widened support to slide, the widened support can realize two-stage sliding adjustment along the chutes and the slide way, the stroke of the widened support in the back and forth sliding process is effectively increased, the adjustment range is wider, the seat arranged on the widened support through the supporting arm can adjust the front and back spacing in a wider range, the comfort for people with different heights is met, and the front and back adjustment of the seat relative to the slide rail is realized electrically through the driving motor, the operation is more stable and reliable during adjustment; in addition, one of the two slide rails is positioned between the two slide grooves, namely, the slide rails are translated inwards on the basis of the existing structure, so that more space is released for the seat passageway position, the width of the passageway is increased, and the space is effectively utilized.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
