Description

TECHNICAL FIELD

[0001] The utility model belongs to electric car hinge accessory technical field relates to a two -wheeled vehicle seat cushion hinge and its stop structure. BACKGROUND

[0002] The current market two -wheeled vehicle, the outer trim piece of seat cushion front lower part is designed with big pit for avoiding the movement space of seat cushion front lower edge, which seriously affects the appearance of the aesthetic appearance, the arrangement of some hinges avoids the pit modeling of seat cushion front lower part trim, in order to design the stop structure of seat cushion hinge, designs the step and the gap in the front part of the seat bucket, causes the seat bucket strength reduction while also unable to guarantee the dustproof waterproof function. Based on above, we design a two -wheeled vehicle seat cushion hinge and its stop structure. SUMMARY

[0003] The utility model discloses a two -wheeled vehicle seat cushion hinge and its stop structure to solve the problem in the background art.

[0004] The utility model discloses a two -wheeled vehicle seat cushion hinge, including hinge piece, seat cushion, seat bucket and seat cushion front lower trim, the inside recess of the middle upper part of the front lateral wall of seat bucket is provided with the hinge piece can be placed, the bottom of inside recess is provided with the rotating installation card seat, the inside of rotating installation card seat is provided with the hinge shaft that is connected with hinge piece, the hinge piece is connected with seat bucket movably through hinge shaft, the front end lower position of seat cushion is provided with the injection molding screw mounting seat, the inside installation hinge fastening screw of screw mounting seat, the seat cushion is integrally injection molded with hinge piece through hinge fastening screw;

[0005] In the two -wheeled vehicle seat cushion hinge, the hinge piece is composed of U type arm, U type lower arm section and U type upper arm section, and the U type arm, the U type lower arm section and the U type upper arm section are integrated structures. The purpose of this arrangement is to use the modeling structure of the hinge piece, avoid the feature modeling of the seat cushion front lower trim, and ensure the integrity of the modeling.

[0006] In the two -wheeled vehicle seat cushion hinge, the middle part of the U type upper arm section is provided with a nut mounting hole, a screw fastening nut is arranged in the nut mounting hole, and the stud of the hinge fastening screw is threadedly connected with the screw fastening nut through the nut mounting hole. The purpose of this arrangement is to make the connection between the hinge fastening screw and the hinge piece more firm, and also reduce the friction between the hinge piece and the hinge fastening screw during opening.

[0007] In the aforementioned two-wheeled vehicle seat hinge, both ends of the hinge shaft are fitted against the outer wall of the seat bucket, and a limiting stop is provided at one end of the hinge shaft. This design aims to prevent the hinge shaft from detaching from the rotating mounting bracket or hinge components during use, thus preventing the seat from separating from the seat bucket.

[0008] In the aforementioned stop structure used in a two-wheeled vehicle seat hinge, the stop structure includes a support end face disposed on a U-shaped lower arm section, the support end face contacting the recessed area. The purpose of this arrangement is to achieve the stop function after the seat is opened by utilizing the weight of the seat and this stop structure, relying entirely on the contact between the end of the U-shaped lower arm section of the hinge and the seat recess, as well as the weight of the seat itself, to achieve the stop.

[0009] Compared with the prior art, the advantages of this utility model of a two-wheeled vehicle seat hinge and its stopping structure are as follows: the hinge component is set as a three-part structure of U-shaped arm, U-shaped lower arm section and U-shaped upper arm section, the overall shape is a horizontal U-shape, the U-shaped lower arm section is arranged at the uppermost part of the middle of the front lower decorative part of the seat and the front side wall of the seat bucket, and the U-shaped upper arm section is installed on the seat with hinge fastening screws. When the seat is opened, the U-shaped shape avoids the feature shape of the front lower decorative panel of the seat, ensuring the integrity of the shape. When it reaches the final position, the supporting end face contacts the concave opening, and the seat's own weight is used to achieve the stopping purpose after the seat is opened.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model relates to a two-wheeled vehicle seat hinge and its stop structure.

[0019] Example: The hinge includes a hinge component 1, a seat cushion 2, a seat bucket 3, and a front lower trim piece 4 for the seat cushion. The front lower trim piece 4 for the seat cushion is installed on the body of the two-wheeled vehicle. The upper middle part of the front side wall of the seat bucket 3 is provided with an inner recess 12 that can accommodate the hinge component 1. The bottom of the inner recess 12 is provided with a rotating mounting bracket 10. The rotating mounting bracket 10 is provided with a hinge shaft 5 connected to the hinge component 1. The hinge component 1 is movably connected to the seat bucket 3 through the hinge shaft 5. The lower front part of the seat cushion 2 is provided with an injection-molded screw mounting seat 9. The screw mounting seat 9 is installed with a hinge fastening screw 6. The seat cushion 2 is integrally injection-molded with the hinge component 1 through the hinge fastening screw 6.

[0020] Furthermore, such as Figure 3 As shown, the hinge component 1 is composed of a U-shaped arm 101, a U-shaped lower arm segment 102 and a U-shaped upper arm segment 103. The U-shaped arm 101, the U-shaped lower arm segment 102 and the U-shaped upper arm segment 103 are an integrated structure, and the overall shape of the hinge component 1 is a horizontally placed U-shape.

[0021] In order to ensure good stability of the connection between the hinge component 1 and the seat cushion 2, a nut mounting hole 7 is provided in the middle of the U-shaped upper arm section 103. A screw fastening nut 8 is installed inside the nut mounting hole 7. The stud of the hinge fastening screw 6 passes through the nut mounting hole 7 and is threadedly fastened to the screw fastening nut 8.

[0022] In this embodiment, in order to prevent the hinge shaft 5 from detaching from the hinge component 1, both ends of the hinge shaft 5 are in contact with the outer side wall of the seat 3, and a limiting baffle 11 is provided at one end of the hinge shaft 5. The purpose of this setting is to prevent the hinge shaft 5 from detaching from the rotating mounting bracket 10 or the hinge component 1 during use, which would cause the seat cushion 2 to separate from the seat 3.

[0023] Example 2: Figure 3 As shown, it also includes a stop structure, which is a support end face 1021 set on the U-shaped lower arm section 102. When opened, the support end face 1021 is located at the top of one side of the hinge member 1. This setting makes the seat cushion 2 have a certain limiting effect after opening. The purpose of stopping the seat cushion 2 after opening is achieved by the weight of the seat cushion 2 and this stop structure.

[0024] This solution, through reasonable spatial arrangement and stop structure design, can not only satisfy the requirement of not damaging the shape of the lower front decorative part 4 of the seat cushion, but also ensure the strength and waterproof and dustproof function of the seat bucket 3, while ensuring that the seat cushion 2 has a good stop effect when it is opened.
