Description

Technical Field

[0001] This utility model relates to the field of folding seat technology, and in particular to a seat folding structure. Background Technology

[0002] As people's demand for convenient travel continues to increase, folding tricycles are becoming increasingly widely used in daily life due to their foldable, portable, and easy-to-store features. However, the existing seat folding structure of electric tricycles has many shortcomings: the folding operation is complicated, lacking a convenient folding and unfolding locking mechanism, often requiring multiple steps to complete the state switch; the support stability is poor, and the seat is prone to shaking after unfolding due to unstable structural connections, posing a safety hazard. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seat folding structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a seat folding structure, including an electric tricycle, a support frame mounted on the electric tricycle, a seat mounted on the upper end of the support frame, the part of the support frame near the front of the vehicle being the front part, and the part of the support frame near the rear of the vehicle being the rear part; a folding component is provided at the connection between the electric tricycle and the support frame.

[0005] Preferably, the folding assembly includes a mounting frame installed at the rear end of the electric tricycle, with a vehicle frame mounted at both ends of the mounting frame, and a backrest movably hinged to the rear end of the top surface of the mounting frame, and the support frame placed inside the vehicle frame.

[0006] Preferably, a support rod is rotatably connected between the lower ends of the two frames, a slide rail is provided on the side of the frame, an inverted J-shaped slide groove is provided at the rear end of the slide rail, and a support rail is installed on the outer side of the far side of the frame.

[0007] Preferably, the lower two sides of the front end of the support frame are movably hinged to the support rod, and a rotating rod is installed laterally at the rear end of the support frame, with rollers rotatably connected to both ends of the rotating rod.

[0008] Preferably, the roller is placed inside the slide rail, with the front end of the roller inside the slide rail in a folded state, and the roller placed in the inverted J-shaped groove at the rear end of the slide rail in an unfolded and locked state.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, through the cooperation of rollers, slide rails, and inverted J-shaped slide grooves, the rollers can slide within the slide rails with the front end in a folded state. When they enter the inverted J-shaped slide grooves, they are unfolded and locked, allowing the seat to be folded and unfolded without complicated operations. Through the cooperation of the support frame and the support rod, the front end of the support frame is hinged to the support rod, and the support rod rotates with the support frame to provide auxiliary support, which enhances the support stability when the seat is unfolded and prevents folding during riding.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-5This utility model discloses a seat folding structure, including an electric tricycle 6, a support frame 1 mounted on the electric tricycle 6, a seat 2 mounted on the upper end of the support frame 1, the part of the support frame 1 near the front of the vehicle being the front, and the part of the support frame 1 near the rear of the vehicle being the rear; a folding assembly is provided at the connection between the electric tricycle 6 and the support frame 1; the top of the support frame 1 facilitates fixing and supporting the seat 2; the seat 2 and backrest 5 facilitate sitting and riding; the folding assembly includes a mounting frame mounted on the rear end of the electric tricycle 6, with a frame 4 mounted on both ends of the mounting frame, and the backrest 5 is movably hinged to the rear end of the top surface of the mounting frame (it can be hinged by a locking knob or a torsion hinge seat, so that the backrest 5 can only tilt and lean towards the seat 2); when the backrest 5 needs to be folded, simply loosen the locking knob or other type of hinge structure, and then the backrest 5 can be folded towards the seat 2; the support frame 1 is placed inside the frame 4; the frame 4 facilitates the folding and unfolding of the support frame 1.

[0019] In this utility model, a support rod 3 is rotatably connected to the lower end of the two frames 4. A slide rail 7 is provided on the side of the frame 4, and an inverted J-shaped groove is provided at the rear end of the slide rail 7. A support rail 10 is installed on the outer side of the frame 4. The support rod 3 facilitates the connection of the support frame 1. The slide rail 7 facilitates the folding and unfolding of the frame 4. The inverted J-shaped groove at the rear end of the slide rail 7 facilitates the locking of the support frame 1. The support rail 10 facilitates the support of the frame 4. The two sides of the lower front end of the support frame 1 are movably hinged to the support rod 3. A rotating rod 9 is installed laterally at the rear end of the support frame 1. Rollers 8 are rotatably connected to both ends of the rotating rod 9. The rotating rod 9 facilitates the rotation of the rollers 8. The rollers 8 facilitate the sliding of the support frame 1 within the frame 4. The rollers 8 are placed inside the slide rail 7. The front end of the rollers 8 inside the slide rail 7 is in a folded state, and the rollers 8 are placed in the inverted J-shaped groove at the rear end of the slide rail 7 in an unfolded and locked state.

[0020] Working principle: When using this invention, if the seat 2 needs to be unfolded, the support frame 1 is pushed to the rear end, and the roller 8 slides within the slide rail 7 of the frame 4. This causes the rotating rod 9 at the rear end to drive the roller 8 to slide along the slide rail 7 to the rear end. At the same time, the front end of the support frame 1 is movably hinged to the support rod 3, and the lower end of the support rod 3 is rotatably connected to the frame 4, thereby unfolding the support frame 1 and the support rod 3. When the roller 8 slides into the inverted J-shaped groove at the rear end of the slide rail 7, the inverted J-shaped groove and the roller 8 form a limit, realizing the unfolded and locked state of the seat 2. At this time, the backrest 5 can cooperate with the seat 2 for easy seating. When the seat 2 needs to be folded, the roller 8 slides out of the inverted J-shaped groove and moves forward along the slide rail 7. The support rod 3 rotates in the opposite direction as the support frame 1 moves. When the roller 8 is located at the front end of the slide rail 7, the seat 2 is in a folded state. When the backrest 5 needs to be folded (when the backrest 5 is hinged using the locking knob), simply loosen the locking knob and then fold the backrest 5 toward the seat 2 to complete the folding and storage operation of the seat 2 and the backrest 5.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
