Description

Technical Field

[0001] The utility model relates to the field of transportation tools, in particular to a multi-functional rear seat device for a two-wheeler. Background Art

[0002] At present, most kindergarten children or lower-grade primary school students are picked up and dropped off by their parents on electric bikes when going to and from school. In winter, children sitting on the rear seat feel cold, and the safety factor is low. Most need windshields or thick clothes to keep warm for children. However, after dropping off the children, due to their thickness and large size, the windshields or thick clothes cannot be carried because the front basket is small. And if an existing basket is fixed at the back, the child cannot sit on the rear seat, and when it rains, the clothes are more likely to get wet. Some parents do not go home after dropping off their children and go directly to work by bike, and it is even more impossible to carry the windshields and thick clothes. Although medium-sized household electric bikes for riding can fix the rear basket, the space is limited and thick windshields and thick clothes cannot be placed, and it can only store items and seems redundant when there are no items to store.

[0004] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0005] A multi-functional rear seat device for a two-wheeler includes an integrally formed seat board and a backrest board. The seat board is assembled with the rear seat. Side plates are respectively rotatably connected to both sides of the seat board. An armrest is provided on one side of the seat board away from the backrest board. Limiting devices adapted to the side plates are provided on both sides of the armrest and both sides of the backrest board.

[0006] Further, the limiting device includes fasteners respectively rotatably provided on both sides of the armrest and both sides of the backrest board. Rectangular notches are provided at positions corresponding to the fasteners on the side plates, and the fasteners can be rotatably inserted into the rectangular notches.

[0007] Further, a rainproof cloth is adhesively bonded to the backrest board through a magic tape, and one end of the rainproof cloth away from the backrest board is adhesively bonded to the armrest through a magic tape.

[0008] Further, both the seat board and the backrest board are metal or injection-molded plastic parts.

[0009] Further, curling edges are provided at both bottoms of both sides of the seat board and both sides of the back of the backrest board, and reinforcing ribs are provided on both the seat board and the backrest board.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] When this patent is in use, especially in winter, the side plates can be rotated to both sides to open the device, making the device into a seat structure. On the one hand, the side plates can protect the feet of children and prevent the feet from getting stuck in the wheels. On the other hand, the windproof cover or thick clothes placed inside can be taken out to keep the children warm. After picking up and dropping off the children, the side plates can be rotated in the reverse direction to close the device, making the device into a storage box structure, and the windproof cover or thick clothes can be placed inside. It can flexibly change its form according to the usage needs to achieve different usage functions, with a wider functionality, a larger storage space, and a wider application range.

[0018] The following further elaborates the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0019] The present utility model relates to a multifunctional rear seat device for a two-wheeled vehicle. The main structure includes an integrally formed seat board 1 and a backrest board 2, and the two together form a traditional L-shaped seat structure. The seat board 1 is assembled with the rear seat through mounting holes and U-shaped clamps. Side plates 3 are respectively rotatably connected to both sides of the seat board 1. The side plates 3 can be rotated downward to open and can also be rotated upward to reset and close. An armrest 4 is provided on the side of the seat board 1 away from the backrest board 2. The armrest 4 is the same as the existing armrest, and the legs of children can pass through the bottom of the armrest 4, which is convenient for sitting and grasping. Limiting devices adapted to the side plates 3 are provided on both sides of the armrest 4 and both sides of the backrest board 2, as shown in FIG Figure 2-4As shown, the limiting device includes buckle plates 5 rotatably arranged on both sides of the armrest 4 and both sides of the backrest 2 respectively. A rectangular notch 6 is provided on the side plate 3 at the position corresponding to the buckle plate 5, and the buckle plate 5 can be rotatably inserted into the rectangular notch 6.

[0020] When a child is sitting, the buckle plate 5 can be rotated to rotate and extract the buckle plate 5 from the corresponding rectangular notch 6, and the side plate 3 is rotated outward and downward to be opened to form a seat structure, which is convenient for the child to sit. The side plate 3 also plays a role in restricting the child's legs and preventing the child's feet from getting stuck in the wheels. The child holds the front armrest 4 with both hands and leans on the backrest 2 behind, which is convenient for the body to maintain balance.

[0021] When no child is sitting, the side plates 3 on both sides can be rotated upward and inward to fit on both sides of the armrest 4 and both sides of the backrest 2, and then the buckle plate 5 is rotated to rotatably insert the buckle plate 5 into the corresponding rectangular notch 6 on the side plate 3 to fix the side plate 3, forming a storage box structure. The warm quilt or thick clothes can be put into this device, which has more comprehensive functions, is more flexible to use, and has a wider application range.

[0022] Preferably, a rainproof cloth 7 is adhesively bonded to the backrest 2 through a magic tape. One end of the rainproof cloth 7 away from the backrest 2 is adhesively bonded to the armrest 4 through a magic tape. When a child is sitting, the end of the rainproof cloth 7 away from the backrest 2 is adhesively fixed to the back of the backrest 2. When no child is sitting, the end of the rainproof cloth 7 away from the backrest 2 is adhesively bonded to the armrest 4, which can block the placement opening formed at the top when this device is used as a storage box structure, and can play a role in protecting the items placed inside from rain, snow and dust.

[0023] Preferably, both the seat board 1 and the backrest 2 are made of metal or injection-molded plastic parts.

[0024] Preferably, curling edges 8 are provided at the bottoms of both sides of the seat board 1 and at both sides of the back of the backrest 2. Reinforcing ribs are provided on both the seat board 1 and the backrest 2, which can enhance the overall strength and rigidity of the device. While further strengthening the rigidity of the product, the curling edges 8 can also prevent the edges from scratching children.

[0025] This patent can be used both as a seat for children to sit and as a storage box to store items. It can flexibly change its form according to the use needs to achieve different use functions, has a wider range of functions, a larger storage space, and a wider application range.
