[Prior Art 3 [0002] According to the regular meeting, some people may suffer from lower body sputum due to serious diseases such as car accidents, strokes, etc., or they may have to go to bed without going to bed because of long-term illness. With shrinking, it is no longer easy to stand up and walk, or the physiology of the elderly can be degraded, causing slowness of movement and the difficulty of walking easily with both feet. These people with limited mobility often need to use crutches or wheelchairs when they want to travel long distances. Supporting the actions of the public, but because such equipment is powered by human power, it is not only extremely labor-intensive, but also has a faster speed, and there are many problems and inconveniences. [0003] So, there are manufacturers who have developed various types of manned vehicle equipment such as electric scooters and electric wheelchairs to use electric energy conversion as a driving force to help people with limited mobility to move and move. However, look at the market. All kinds of manned vehicle equipment can achieve the expected effect of using electric energy conversion as power for people with limited mobility to facilitate activities; and the seats of general manned vehicles are mostly monolithic structural design, and It can't be folded and folded, and the unfolding is only a fixed angle. Therefore, the user has the trouble of being extremely inconvenient to accommodate and comfortable to ride. Although the manufacturer uses the detachable method to reduce the space occupied by the manned vehicle, Disassembly and assembly 098110124 Form No. 1010101 Page 4 of 17 Page 1003308978-0 13.53937. It is not only costly but also inconvenient to perform the operation in the replacement of the 100-year process on August 23, 100. There is still room for improvement in the manned vehicle on the issue of the folding. [0004] The reason is that the inventor has in view of this, and has been rich in design and development and practical production experience of the relevant industry for many years, and has researched and improved the existing structure and defects to provide a seat device for electric scooter, in order to achieve more The purpose of good practical value. SUMMARY OF THE INVENTION [0005] The present invention provides a seat device for an electric scooter, which is a seat structure having a folding and unfolding limit, and has a limit function of a concave-convex body. The seat has a suitable expansion space and a restraining effect. [0006] The purpose and function of a seat device for an electric scooter according to the present invention is achieved by the following technology: [0007] The seat is mainly formed by a seat corresponding to a pivotal seat back, and the seat back is from the front The rear seat back is combined, wherein the pivotal end of the seat is provided with a fan-shaped limiting protrusion, and can be correspondingly embedded in the fan-shaped recess of the rear seat back pivoting end, so that the fan-shaped limiting protrusion can be in the fan shape There is a restriction space for the rotational displacement in the groove, thereby allowing the seat back of the seat to reach the range of motion with deployment and retraction. [0008] The seat device of the electric scooter further has a reinforcing edge rib with increased strength at the combination of the back of the chair and the back of the seat back before the seat back, so as to increase the strength of the backrest and make it more inclined. It has a supporting effect and is more practical and practical in its overall implementation. 098110124 Form No. A0101 Page 5 of 17 1003308978-0 1353937 [0009] ["ίΰοί年丝丝 The present invention is an electric scooter seat device which is attached to the bottom of the seat. Into the slot of the assembled armrest, so that the armrest can be directly assembled to achieve the convenience of assembly. [0012] [0014] [Embodiment] In order to make the technical content, the object of the invention and the effects thereof achieved by the present invention more complete and clear, the following is explained in detail. Please also refer to the illustrated drawings and drawings: First, please refer to the second to the second figure, which is a three-dimensional decomposition and combination diagram of the seat device of the electric scooter according to the present invention. The seat (A) is mainly The seat (1) is pivotally coupled with the seat back (2) which is composed of a combination of front and rear seat backs (2 1) and (2 2), wherein: the seat (1) is provided with a pivot end ( 1 1), a fan-shaped limiting protrusion (1 2) is arranged on the connecting end (1 1 ), and first and second concave holes are respectively arranged at two corresponding ends of the fan-shaped limiting protrusion (12) (1 2 1 ), (1 2 2 ); the back (2 2) of the seat back (2) is extended with a pivotal end (2 21) and a pivotal end of the seat (1) (1 1 Corresponding to the pivotal connection, the pivotal end (2 2 1 ) of the rear seat back (2 2) is provided with a rotational displacement of the sector-shaped limiting protrusion (12) of the pivotal end (1 1 ) of the seat (1). Fan-shaped groove (2 2 2 ), and fan-shaped groove (222) respectively There stopper boss with the sector (12) of the first and second recesses (121), (122) fitted to the first card, the second bumps (223), (224) by. Please refer to the first to second, third to sixth figures, for the present invention, a 098110124 form number A0101, page 6 / a total of 7 pages, 1003308978-0 1^53937 Λ 100 years, August 23, according to the replacement page The action of the seat device of the electric scooter and the enlarged cross-sectional view, when assembled (also in the unfolded state), the first and the back of the seat back (2 1 ), (2 2 ) are correspondingly arranged. In the combination of the front seat back (2 1 ) and the rear seat back (22), a reinforcing edge rib (2 1 1 ) with increased strength is provided to increase the strength of the seat back (2), so that it can be tilted. More supportive effect; then, the pivotal end (2 2丄) extended on both sides of the back seat back (2 2) is combined with the pivot end (11) of the seat (i), and at the same time, the chair is allowed The fan-shaped limiting protrusion (12) of the seat (i) corresponds to the sector-shaped groove (2 22) embedded in the rear seat back (22), and the first concave hole of the sector-shaped limiting protrusion (12) (1 2) 1) Corresponding to the first bump (2 2 3) fitted into the sector groove (2 2 2 ), so that the assembly can be positioned in the unfolded state. [0015] When the seat back (2) is folded, the seat back (2) is pushed to rotate at the center of the plugs 4 (11) and (221), and the rear seat # ( 2 2) is fan-shaped. The groove (2 2 2 ) is rotated corresponding to the fan-shaped limiting protrusion (12), so that the _th convex (223) of the fan-shaped groove (222) is separated from the first concave of the fan-shaped limiting protrusion (12) a hole (12 1), and the second protrusion (2 2 4 ) of the sector groove (222) is correspondingly embedded in the second recess (1 2 2) of the fan-shaped limiting protrusion (12), so that The back of the seat (2) is folded against the seat (1) and has a positioning effect at the same time.
