Description

Technical Field

[0001] This utility model relates to the field of electric-assisted bicycle technology, specifically to a rear seat for an electric-assisted bicycle. Background Technology

[0002] Electric-assisted bicycles are a type of electric bicycle that uses an electric motor to provide auxiliary power corresponding to the pedaling force. Compared to traditional pedal bicycles, electric-assisted bicycles are more labor-saving and practical. The rear seat of existing electric-assisted bicycles often adopts the same structure as traditional bicycles, using two support rods with one end welded to the rear seat and the other end connected to the rear wheel axle. At the same time, a fixing rod connecting the front seat post is welded to the rear seat in the direction facing the front seat, so that the bicycle's rear upper fork, rear seat frame, and support rods form a stable triangular structure.

[0003] Existing electric bicycle rear seats are prone to damage during use, have a short lifespan, and are mostly installed using bolts, requiring specific wrenches for disassembly and replacement, which is inconvenient for users. Therefore, we propose a new type of rear seat for electric bicycles. Utility Model Content

[0004] The purpose of this invention is to provide a rear seat support for an electric-assisted bicycle, thereby solving the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rear seat for an electric-assisted bicycle, comprising a seat plate, a fixing post fixedly installed at the bottom end of the seat plate, a seat cushion provided at the top end of the seat plate, a fixing component provided between the seat cushion and the seat plate, and a seat cover covering the top end of the seat cushion;

[0006] The fixing assembly includes a positioning rod and a locking plate. The positioning rod is fixedly installed at the bottom end of the seat cushion. The seat plate has a positioning hole through which the positioning rod movably passes. The locking plate has a rotating hole through which it rotatably fits onto the outer wall of the fixing column. The outer wall of the positioning rod has a locking groove into which the locking plate engages. A fixing frame is fixedly installed at the bottom end of the locking plate. A pin movably passes through the fixing frame and the locking plate. A pin groove is provided at the bottom end of the seat plate, into which the pin is inserted. A baffle is fixedly fitted onto the outer wall of the pin. A spring is fixedly connected between the bottom end of the baffle and the inner wall of the fixing frame, and the spring surrounds the outer wall of the pin.

[0007] Preferably, there are three positioning rods and three positioning holes, and the positioning rods and positioning holes are compatible. By setting the positioning rods and positioning holes, the seat cushion can be limited.

[0008] Preferably, the card plate is adapted to the card slot, and the pin is adapted to the pin slot. By setting the card plate, the card plate can be inserted into the card slot, thereby limiting the positioning rod. By setting the pin, the pin can be inserted into the pin slot, thereby limiting the card plate and ensuring the stability of the card plate in the card slot.

[0009] Preferably, a limiting ring plate is fixedly installed on the inner wall of the rotating hole, and a limiting ring groove is formed on the outer wall of the fixed column. The limiting ring plate and the limiting ring groove are rotatably connected.

Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-6As shown, this utility model provides a technical solution: a rear seat for an electric bicycle, including a seat plate 1, a fixing post 2 fixedly installed at the bottom end of the seat plate 1, a seat cushion 3 provided at the top end of the seat plate 1, a fixing component provided between the seat cushion 3 and the seat plate 1, and a seat cover 4 covering the top end of the seat cushion 3.

[0026] The fixing assembly includes a positioning rod 9 and a clamping plate 11. The positioning rod 9 is fixedly installed at the bottom end of the seat cushion 3. A positioning hole 10 is provided on the seat plate 1, through which the positioning rod 9 movably passes. A rotating hole 15 is provided on the clamping plate 11, through which the clamping plate 11 rotatably fits onto the outer wall of the fixing post 2. A groove 12 is provided on the outer wall of the positioning rod 9, through which the clamping plate 11 is engaged. A fixing frame 16 is fixedly installed at the bottom end of the clamping plate 11. A pin 17 movably passes through the fixing frame 16 and the clamping plate 11. A pin groove 18 is provided at the bottom end of the seat plate 1, through which the pin 17 is inserted. A baffle 19 is fixedly fitted on the outer wall of the pin 17. A spring 20 is fixedly connected between the bottom end of the baffle 19 and the inner wall of the fixing frame 16, and the spring 20 surrounds the outer wall of the pin 17.

[0027] The base plate 1 can be any desired shape, such as a rectangle, triangle or trapezoid, etc. The mounting bracket at the bottom of the base plate 1 is all existing technology and is not described or drawn in this article and the accompanying drawings.

[0028] Specifically, in the above technical solution, when the old or damaged seat cushion of the electric-assisted bicycle needs to be replaced, the pin 17 can be pulled down, causing the pin 17 to drive the baffle 19 to compress the spring 20, thus disengaging the pin 17 from the pin groove 18. This removes the pin 17 from the locking plate 11, allowing the locking plate 11 to rotate and disengage from the locking groove 12, thus removing the locking plate 11 from the positioning rod 9.

The new seat cushion is then installed on the seat plate 1, inserting the positioning rod 9 into the positioning hole 10. The locking plate 11 is then rotated in the opposite direction, causing the locking plate 11 to... Insert the pin into the slot 12, then loosen the support rod 17 so that the pin 17 is inserted into the pin groove 18, thus completing the installation of the new seat 3. The above structure facilitates the disassembly and replacement of the seat, improving replacement efficiency. Furthermore, by setting the seat cover 4, the seat cover 4 can be placed on the seat when the electric bicycle is not in use, thereby protecting the seat and extending its service life. This solves the problem that the existing electric bicycle rear seat 3 is easily damaged during use, has a short lifespan, and the installation method of the seat is mostly bolt-fixed connection, which requires the use of specific wrenches when disassembling and replacing it, making it inconvenient for personnel.

[0029] Furthermore, there are three positioning rods 9 and three positioning holes 10, and the positioning rods 9 and the positioning holes 10 are compatible.

[0030] The seat cushion 3 can be limited by setting the positioning rod 9 and the positioning hole 10.

[0031] Furthermore, the card plate 11 is adapted to the card slot 12, and the pin 17 is adapted to the pin slot 18;

[0032] Specifically, by setting a locking plate 11, the locking plate 11 can be locked into the locking groove 12, thereby limiting the positioning rod 9. By setting a pin 17, the pin 17 can be inserted into the pin groove 18, thereby limiting the locking plate 11 and ensuring the stability of the locking plate 11 in the locking groove 12.

[0033] Furthermore, a limiting ring plate 13 is fixedly installed on the inner wall of the rotating hole 15, and a limiting ring groove 14 is opened on the outer wall of the fixing column 2. The limiting ring plate 13 and the limiting ring groove 14 are rotatably connected.

[0034] By setting the limiting ring plate 13 and the limiting ring groove 14, the clamping plate 11 can be limited, so that the clamping plate 11 can be fixed and rotated on the fixed column 2.

[0035] Furthermore, a hanging plate 5 is fixedly installed on the outer wall of the seat cover 4, and a hanging hole 7 is provided on the hanging plate 5. An L-shaped hanging rod 6 is fixedly installed on the outer wall of the seat plate 1, and the hanging plate 5 is hung on the L-shaped hanging rod 6 through the hanging hole 7.

[0036] The seat cover 4 can be fixed or stored when in use or not by setting up the hanging plate 5 and the L-shaped hanging rod 6, so that people can use it at any time.

[0037] Furthermore, the outer wall of the L-shaped hanging rod 6 is fixedly fitted with a rod sleeve 8, which is made of wear-resistant rubber.
