DETAILED DESCRIPTION

[0020] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] As Figures 1 to 4 The portable folding seat of the embodiment comprises a seat body 1, a backrest 2 and an armrest 3.

[0022] The rear end of the seat body 1 is hingedly connected to the bottom of the backrest 2 through a folding hinge 4 to realize angle-adjustable rotating positioning. The specific folding hinge 4 can adopt an existing structure, for example, a sofa hinge, a bed hinge or other folding and positioning folding hinges 4, which can be adjusted and positioned at multiple angles.

[0023] The armrest 3 is arranged on one side of the seat body 1 and the backrest 2, and the armrest 3 comprises an upper armrest 31 and a lower armrest 32 which are hingedly connected to each other. The end of the lower armrest 32 away from the upper armrest 31 is hingedly connected to the seat body 1, and the end of the upper armrest 31 away from the lower armrest 32 is hingedly connected to the backrest 2.

[0024] The upper armrest 31 and the lower armrest 32 are hingedly connected through a hinge assembly 5. The hinge assembly 5 comprises a first hinge piece 51 and a second hinge piece 52. One end of the first hinge piece 51 is a first fixed end 511 fixedly connected to the upper armrest 31. The other end of the first hinge piece 51 extends outward relative to the upper armrest 31 and is bent towards the front of the upper armrest 31 to form a first hinge end 512. The first hinge end 512 and the first fixed end 511 are arranged at an obtuse angle. One end of the second hinge piece 52 is a second fixed end 521 fixedly connected to the lower armrest 32. The other end of the second hinge piece 52 extends outward relative to the lower armrest 32 and is bent towards the front of the lower armrest 32 to form a second hinge end 522. The second hinge end 522 and the second fixed end 521 are arranged at an obtuse angle. The terminal ends of the first hinge end 512 and the second hinge end 522 are hingedly connected to each other and can form a "V" shape. The terminal ends of the first hinge end 512 and the second hinge end 522 are coaxial.

[0025] The backrest 2 can be rotated to unfold into a seat shape with the seat body 1, or completely unfolded into a cushion shape with the seat body 1, or folded to be stored above the seat body 1.

[0026] When the seat of the present embodiment is placed on a stand for use, the backrest 2 can be rotated and unfolded relative to the seat body 1 by about 90 degrees by the folding hinge 4, and can be positioned. Of course, the specific angle of the backrest 2 can be adjusted by a certain angle according to the model function of the folding hinge 4, and at the same time, the upper armrest 31 and the lower armrest 32 of the armrest 3 are hinged to the front side to make the seat in a seat state (as shown in Figure 1 ), the upper armrest 31 and the lower armrest 32 can be unfolded by about 90 degrees by the hinge assembly 5, and the lower armrest 32 can be arranged in front of the backrest 2, and the upper armrest 31 can be arranged horizontally above the seat body 1, so that when a user sits on the seat body 1 and leans back on the backrest 2, the arms can be placed on the unfolded armrest 3 for rest and relaxation, thereby improving the user experience. At this time, the first hinge end 512 and the second hinge end 522 are protruding upward.

[0027] When the user wants to lie down for use, the backrest 2 can be rotated and unfolded relative to the seat body 1 by about 180 degrees, that is, the backrest 2 is unfolded backward to form a cushion, and at this time, the upper armrest 31 and the lower armrest 32 of the armrest 3 can also be unfolded by the hinge assembly 5. 5 is arranged on the side of the seat, which does not affect the user to lie down and rest, and the first hinge end 512 and the second hinge end 522 can be protruding upward.

[0028] When the seat is not needed, the backrest 2 can be rotated forward relative to the seat body 1 and folded together, so that the backrest 2 is stacked above the seat body 1 to reduce the volume and size of the product, and facilitate storage. At this time, the armrest 3 can be arranged by the hinge assembly 5, so that the upper armrest 31 and the lower armrest 32 are arranged in a stacked manner, and the first hinge end 512 and the second hinge end 522 are protruding rearward.

[0029] Therefore, by arranging the hinge assembly 5, the first hinge end 512 and the second hinge end 522 can be conveniently used to freely rotate the upper armrest 31 and the lower armrest 32 of the armrest 3, and the hinge of the upper armrest 31 and the lower armrest 32 can be freely protruded in the forward and rearward directions, that is, the upper armrest 31 and the lower armrest 32 can be freely bent forward (as shown in Figure 1 ) or bent backward (as shown in Figure 3 ), which can realize forward unfolding, backward unfolding or upward and downward stacking.

[0030] In the present embodiment, the seat body 1 and the backrest 2 are provided with armrests 3 on the left and right sides. To facilitate use, of course, only one side of the armrest 3 can also achieve the corresponding function.

[0031] Meanwhile, two hinge assemblies 5 can be arranged between the upper handrails 31 and the lower handrails 32 at left and right sides, and the two hinge assemblies 5 are arranged at left and right sides of adjacent ends of the upper handrails 31 and the lower handrails 32, so as to increase the connection stability, and the ends of the upper handrails 31 and the lower handrails 32 between the two hinge assemblies 5 can be spaced from each other, without affecting the movement of the handrails 3.

[0032] Specifically, the first fixed end 511 can be welded and fixed with the upper handrail 31, the second fixed end 521 can be welded and fixed with the lower handrail 32, and the ends of the first hinge end 512 and the second hinge end 522 are provided with hinge holes 53, and a hinge shaft (not shown in the figure) is arranged in the two adjacent hinge holes 53. The hinge shaft can be a rivet, a pin shaft, a bolt, etc.

[0033] In the embodiment, the seat body 1 and the backrest 2 can each include a rectangular frame body 6, and the two frame bodies 6 can be connected through two left and right spaced folding hinges 4.

[0034] The frame body 6 is provided with a handrail connecting frame 7 at a position away from the intersection of the seat body 1 and the backrest 2 at left and right sides, respectively, and the two handrail connecting frames 7 at the same side are used for hinge connecting the upper handrail 31 and the lower handrail 32 of the handrail 3 at the same side.

[0035] The outer periphery of the seat body 1, the backrest 2 and the handrail 3 can be covered with a flexible cloth cover (not shown in the figure), so as to provide a comfortable sitting experience.

[0036] In the embodiment, the middle part of the frame body 6 away from the intersection of the seat body 1 and the backrest 2 can be flattened to form a flat rod body 61, so that the thickness of the position can be smaller after the cloth cover is covered, and it is convenient to take.

[0037] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that equivalent changes and modifications made by those skilled in the art without departing from the principles of the present application shall still fall within the protection scope of the present application.
