Technical Field

The invention relates to the technical field of bicycles, in particular to a deformable rear seat of a bicycle with a loading function.

Background

The bicycle is the most common tool for riding instead of walk in life, and plays an important role in the life of the masses. The bicycle backseat is generally formed by combining and welding a plurality of steel bars and has the functions of carrying people and objects. However, the shape of the rear seat is generally uneven, the material is often hard, and the comfort of the rear seat in the manned process cannot be guaranteed. In addition, the size of the article is generally small, and the article with a large size cannot be carried, so that auxiliary tools such as binding ropes and the like are often needed. The utility model patent cn201520796005.x discloses a novel stretchable bicycle rear seat for this problem, with an increased amount of carriers by a strategy of changing the rear seat surface area. The invention patent 201410429507.9 discloses a bicycle backseat, which is characterized in that an external expansion frame set is unfolded in a reverse mode to achieve the conversion of manned and objective functions.

Disclosure of Invention

The invention provides a technical scheme of a deformable rear seat of a bicycle with a loading function. According to the technical scheme, the bicycle backseat with the cushion is unfolded and deformed into a frame body with a larger size through a cross unfolding structure, so that large articles can be conveniently borne. The specific invention content is as follows:

the technical scheme adopted by the invention is a deformable rear seat of a bicycle with a cargo carrying function, and the deformable rear seat of the bicycle comprises a bottom support (1), a left side turnover plate (2), a left side stretching plate (3), a right side turnover plate (4), a long seat supporting frame (5), a short seat supporting frame (6), a right side stretching plate (7) and a cushion (8).

The left side turnover plate (2) and the right side turnover plate (4) are connected with the bottom support (1) through hinges. The right side turnover plate (2) and the right side stretching plate (7) form a sliding pair, the right side turnover plate (4) is extended by the right side stretching plate (7) to be 75mm long, and the right side stretching plate (7) is self-locked at any position in the extension range. The left side returning face plate (2) is connected with the left side stretching plate (3) through a buckle of the short seat supporting frame (6), the relative position of the left side stretching plate (3) and the short seat supporting frame (6) is fixed, the left side returning face plate (2) and the left side stretching plate (3) form a moving pair, the left side stretching plate (3) extends the left side returning face plate (2) by 75mm, and the short seat supporting frame (6) can be locked at any position in the extension range. The cushion (8) and the left stretching plate (3) are relatively fixed. Seat length support frame (5) and left side returning face plate (2) relatively fixed, seat length support frame (5) are connected for dismantling with collet (1), and when bicycle deformable backseat was closed to be packed up, seat length support frame (5) were connected through the buckle with collet (1).

Furthermore, when the bicycle deformable backseat is opened, the soft rope penetrates through the reserved round holes in the left side overturning plate (2), the right side overturning plate (4), the left side stretching plate (3) and the right side stretching plate (7), the whole structure is changed into a frame body, and the function of loading large-sized articles is achieved.

Furthermore, the left side turnover plate (2) can be rotated to be opened and closed at 110 degrees, and the right side turnover plate (4) can be rotated to be opened and closed at 115 degrees.

Furthermore, the cushion (8) is made of soft materials (rubber, sponge, cotton and linen filler and the like).

Further, when the deformable rear seat of the bicycle is closed and folded, the bicycle becomes a cuboid-like seat. When a passenger sits on the seat cushion (8), two seat long support frames (5) and three seat short support frames (6) in the deformable backseat of the bicycle support the weight of the passenger together.

Compared with the prior art, the driving backseat is generally formed by the combined welding of a plurality of reinforcing bars, and has the functions of carrying people and objects. However, the bicycle backseat is generally small in size, cannot carry articles with large size, and often needs auxiliary tools such as binding ropes. Moreover, the shape of the backseat is generally uneven, the material is often hard, the comfortableness of the backseat in the manned process cannot be guaranteed, and if the riding comfortableness of the manned bicycle is guaranteed, the carrying capacity of the backseat is sacrificed by adding the cushion to the backseat of the bicycle. The invention improves the riding comfort of people and further increases the carrying space of the bicycle backseat on the basis of not sacrificing the carrying capacity of the bicycle backseat.
