[0002] The vehicle seats used in the prior art generally have backrests that can be rotated and adjusted to achieve passenger's sitting posture adjustment. Such seats are generally set on the driver or co-driver seat, while the rear seats of the vehicle are generally unable to be adjusted due to spatial position settings. The current technical problem is that the rear space is larger than the front driver and co-driver space and has a higher utilization rate, but the actual usage is that, under normal circumstances, the rear seats cannot be reversed, so the backrests limit the utilization of the rear space and cannot be used reasonably and effectively. Summary of the invention
[0003] The object of the present invention is to provide a flip-adjustable seat to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a flip-adjustable seat, comprising a seat body and an angle adjuster installed on one side of the seat body, the angle adjuster comprising a base portion fixedly connected to one side of the seat cushion and an adjusting portion rotatably connected to the base portion at one end and fixed to a backrest portion at the other end, a back panel being provided on the back of the backrest, the adjusting portion being used to realize a plurality of preset flipping angles of the backrest portion and to enable the backrest portion to have a preset flipping angle for flipping to a horizontal placement position of its back panel, a locking structure being provided in the angle adjuster, the locking structure comprising a mating piece 1 provided on the adjusting portion and rotating following the rotation path of the adjusting portion, and a mating piece 2 provided on the base portion and locking the mating piece 1 at a preset position of the rotation path of the adjusting portion, the mating piece 2 locking the mating piece 1 to form a horizontal placement position or a placement position of other rotation angles of the back panel.
[0005] The adjustment portion includes a plate component 1 fixedly connected to the backrest portion, and a plate component 2 formed at the other end of the plate component 1 and rotatably connected to the base portion. The matching component 1 is configured as a folding portion formed at the outer edge of the plate component 2, and the end of the folding portion is formed with a stop end for locking the matching component 2. After the stop end is locked with the matching component 2, a horizontal angle placement position of the back panel is formed.
[0006] The adjustment part includes a plate part 1 fixedly connected to the backrest part, and a plate part 2 formed at the other end of the plate part 1 and rotatably connected to the base part, the plate part 2 is formed with a matching part 1 arranged in a segmented manner, the matching part 1 includes a first folding part formed on one side of the outer edge of the plate part 2, and a second folding part formed on the other side of the outer edge of the plate part 2, the end of the first folding part is formed with a first stop end for locking the matching part 2, the first stop end is used to form a first preset rotation angle of the backrest part, and forms a horizontal angle placement position of the backboard after locking with the matching part 2; the end of the second folding part is formed with a second stop end for locking the matching part 2, the second stop end is used to form a second preset rotation angle of the backrest part, and forms other preset angle positions of the backboard after locking with the matching part 2; the matching part 2 is arranged on the rotation path between the first folding part and the second folding part.

DETAILED DESCRIPTION
[0019] The present invention will be further described below in conjunction with the accompanying drawings:
[0020] like Figure 1-7 The flip-adjustable seat shown in the figure includes a seat body 5 and an angle adjuster installed on one side of the seat body 5, the angle adjuster includes a base portion 2 fixedly connected to one side of the seat cushion and an adjusting portion with one end rotatably connected to the base portion 2 and the other end fixedly connected to the backrest portion 51. It should be pointed out that the technical solution adopted by this type of adjustable seat in actual application is to provide limitations with one or more angle positions, so that the backrest portion 51 of the seat body 5 can be placed in a horizontal position or at other preset angles; in order to ensure that the backrest portion 51 is in a horizontal position After being folded to the horizontal position, there is an effectively usable horizontal surface, that is, the horizontal surface can be used for passengers to lie flat or place items, etc. In this embodiment, a back panel 511 is provided on the rear end surface of the backrest portion 51. The surface of the back panel 511 is flat, and the surface can be further modified and improved according to the user's choice. For example, it can be set to a leather surface, which can be suitable for the user to lie flat on the back panel 511 after folding, or a grid-shaped area block can be set on the back panel 511 to realize the partitioned placement of goods, etc. This embodiment does not further limit and explain the optimization scheme of the back panel 511.
[0021] It is important to explain that the adjustment part 1 is a part of the angle adjuster, which is rotatably connected to the base part 2, and the base part 2 is fixedly connected to the side of the seat. By adjusting the rotation angle of the adjustment part 1, multiple preset flip angles of the backrest 51 can be set and the backrest 51 can have a preset flip angle set to the horizontal position of the back plate 511. In order to achieve the horizontal placement of the back plate 511, a locking structure is provided inside the angle adjuster. The locking structure includes a matching part 1 arranged on the adjustment part 1 and rotating along the rotation path of the adjustment part 1, and a matching part 1 arranged on the base part 2 and locks the matching piece 2 of the matching piece 1 at a preset position of the rotation path of the adjustment part 1, so as to realize the angle limitation of the rotation angle through the limitation of the two; in order to realize this limiting setting, in this embodiment, preferably, the adjustment part 1 includes a plate 11 fixedly connected to the backrest part 51, and a plate 2 12 formed at the other end of the plate 11 and rotatably connected to the base part, that is, it can be understood that the plate 11 and the plate 2 12 are an integrated structure, and in order to realize the locking structure with the matching piece, a folding portion is formed at the outer edge of the plate 2 12, and the folding portion has two different implementations, specifically:
[0022] Embodiment 1:
[0023] In this embodiment, the folding portion is used only to limit the horizontal plane angle of the back plate 511. The end of the folding portion is formed with a stop end for locking the second mating piece. Specifically, the folding portion is set to a first folding portion 13 that rotates counterclockwise toward the second mating piece, and a first stop end 131 is formed at the end of the first folding portion 13. In order to achieve locking with the second mating piece, the first stop end 131 adopts a surface-to-surface contact method to achieve positioning. At the same time, in order to further illustrate its locking principle and structure, the second mating piece used is an L-shaped plate structure, see Figure 6 As shown, the positioning portion 3 in the figure is the second matching member, including a base portion 31 fixedly connected to the base portion 2, and a blocking portion 32 integrally formed with the base portion 31 and bent 90°. In a specific implementation, when the first stop end 131 contacts the blocking portion 32, due to interference limitation, and under the action of gravity of the backrest 51, the limitation of the structure is achieved. It should be pointed out that although the first stop end 131 and the blocking portion 32 only have a limiting relationship, at the same time, after the conflict, a horizontal angle of the back plate 511 is formed. It can be placed in a certain position, but when used in conjunction with the elastic locking component 4, the backrest 51 can be locked in a limited position. It should be pointed out that the angle adjuster in the prior art contains an elastic locking component 4, which is installed on a locking component base 41, and the locking component 41 is formed on the plate 12; in a specific implementation, the first stop end 131 contacts the positioning portion 3 for a limited position and then is locked by the elastic locking component 4, which can play an effective double limiting role.
[0024] Embodiment 2:
[0025] The present embodiment, based on the first embodiment, can not only realize the horizontal plane angle limitation of the back plate 511, but also enable the back plate 511 to have other angle limitation functions. On the basis of the first embodiment, the folding portion is configured as a first folding portion 13 that rotates counterclockwise toward the second mating piece and a second folding portion 13 that rotates clockwise. At the same time, a second stop end 141 is formed at the port of the second folding portion 13. In order to realize the locking of the second mating piece, the second stop end 141 also adopts a surface-to-surface contact method to realize the limitation. When the backrest portion 51 rotates clockwise, the first stop end 131 of the first folding portion 13 is blocked with one side of the blocking portion 32 of the positioning portion 3 to realize positioning. When the backrest portion 51 rotates counterclockwise, the second stop end 141 of the second folding portion 14 is blocked with the other side of the blocking portion 32 of the positioning portion 3 to realize positioning. At the same time, the blocking position of the counterclockwise rotation is generally the maximum rotation angle of the backrest portion 51 of the seat. The present embodiment does not limit the maximum rotation angle of the backrest portion 51.
[0026] At the same time, based on the first and second embodiments, it should be noted that the rotation path of the adjustment portion refers to the rotation path of the adjustment portion at the rotation end of the second plate 12, specifically, as follows: Figure 4 and Figure 6 As shown, a notched edging 121 is formed at the outer edge of the plate 2 12, and the notched edging 121 can be understood as having no folding structure, so that a notched edging 121 without a folding portion is formed between the first stop end 131 and the second stop end 141 along the outer edge of the end of the plate 2 12. Since the notched edging 121 has no folding structure, the notched edging 121 cannot interfere with the positioning portion 3 during the rotation of the plate 2 12. Once interference occurs, the first stop end 131 or the second stop end 141 interferes with the positioning portion 3 and achieves further limiting effect.
[0027] The embodiments described above are merely descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
