DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figure 1-6 ;

[0025] A rotatable and replaceable electric bicycle seat comprises a bracket 1 and a double-sided seat body 2. Preferably, the size, structure and appearance design of the two ends of the double-sided seat body 2 of the utility model are the same. The double-sided seat body 2 extends a connecting portion 31, which is rotatably connected to the bracket 1. An automatic reset locking mechanism 3 is provided in the bracket 1. The automatic reset locking mechanism 3 can be engaged with the connecting portion 31 and automatically reset after being unlocked. When the double-sided seat body 2 is scalded by the sun or wet by rain, the automatic reset mechanism is first unlocked, and then the double-sided seat body 2 is rotated 180 degrees. After the double-sided seat body 2 is rotated 180 degrees, the automatic reset mechanism is automatically locked, so that the cold-sided seat is locked at the upper end, and the rider can sit on the cool seat, which solves the problem that the rider cannot sit directly on the double-sided seat body 2 when the seat is scalded by the sun or wet by rain. A carrying ring is provided on the top of the bracket 1 for easy carrying.

[0026] The automatic reset locking mechanism of the present utility model adopts two structural modes, and the two structures are respectively described below.

[0027] Implementation structure one: automatic reset locking mechanism 3 includes a bearing sleeve 33 fixedly connected to the connecting portion 31, and symmetrical sockets 331 are formed on the bearing sleeve 33, and a pull rod 34 is clamped on one of the sockets 331. The pull rod 34 in this embodiment is located at the top of the bracket 1, and the pull rod 34 moves downward and is inserted into the socket 331 to fix the bearing sleeve 33, so that the double-sided cushion body 2 cannot rotate. A rotating bearing 32 rotatably connected to the connecting portion 31 can also be provided directly between the connecting portion 31 and the bearing sleeve 33 to improve the smoothness of the rotation of the connecting portion 31. A pull ring is provided on the top of the pull rod 34 to facilitate the user to lift the pull rod 34. The pull rod 34 is located on the outside of the bracket 1 and is threadedly connected to a nut 341. The nut 341 is used to limit the downward movement distance of the pull rod 34 to ensure that the pull rod 34 will not fall off. The end of the pull rod 34 away from the nut 341 is threadedly connected to a nut 2 34 2. Nut 2 342 is used to limit the lifting height of the pull rod 34 to avoid pulling out the pull rod 34 due to excessive force. In addition, if nut 2 342 is set at the end of the pull rod 34, the pull rod 34 will not be able to be inserted into the socket 331, thereby failing to lock the bearing bushing 33. Therefore, nut 2 342 is not at the end of the pull rod 34, but at a position close to the end. Through the cooperation of nut 1 341 and nut 2 342, the pull rod 34 can only be lifted and lowered at the position between the two nuts. Nut 2 342 is located between the bearing bushing 33 and the bracket 1 to avoid completely pulling out the pull rod 34. A spring 343 is provided on the pull rod 34, one end of the spring 343 abuts against nut 2 342, and the other end abuts against the inner wall of the bracket 1. When the pull rod 34 is lifted upward, the spring 343 will be compressed. When the pull rod 34 is released, the spring 343 will automatically recover and the pull rod 34 will automatically move downward.

[0028] Specifically, the pull rod 34 is lifted to release the lock of the bearing bushing 33. After the pull rod 34 is lifted, the nut 2 342 compresses the spring 343, and the double-sided seat cushion body 2 is manually rotated 180°. When the double-sided seat cushion body 2 rotates, the bearing bushing 33 will also rotate together, thereby turning the lower end socket 331 to the upper end. When the socket 331 rotates to correspond to the pull rod 34, the spring 343 causes the pull rod 34 to automatically move downward and insert into the socket 331, thereby locking and fixing the double-sided seat cushion body 2.

[0029] Embodiment 2: The automatic reset locking mechanism 3 includes a motor 35, and the output shaft of the motor 35 is connected to a planetary reducer 36. The motor 35 and the planetary reducer 36 are connected by a flange. If the motor 35 requires an extremely low speed and must continue to operate at full torque under special working conditions, relying solely on the performance of the servo motor 35 itself is not enough to meet the task requirements. By arranging a planetary reducer 36 at the output end of the servo motor 35, the speed of the servo motor 35 can be effectively reduced while increasing the torque. The planetary reducer 36 is connected to the connecting part 31, and the connecting part 31 extends to the outside of the bracket 1 and is fixedly connected to the double-sided seat cushion body 2. The output shaft of the motor 35 is connected to the input shaft of the planetary reducer 36. When the output shaft of the servo motor 35 rotates, it drives the input shaft of the planetary reducer 36 to rotate, and through a series of gear meshing transmission inside the planetary reducer 36, the output shaft of the planetary reducer 36 is driven to rotate. The rotation of the output shaft of the planetary reducer 36 drives the connecting part 31 to rotate, thereby rotating the double-sided seat cushion body 2.

[0030] Furthermore, the output end of the planetary reducer 36 is fixedly connected to a flange rotating disk 39, on which magnets are symmetrically arranged, and the bracket 1 is symmetrically provided with Hall sensors 38 for sensing magnets 392, and the flange rotating disk 39 is also symmetrically provided with lock holes 391, and the symmetrically arranged lock holes 391 and magnets 392 are cross-distributed, and the bracket 1 is also provided with an electromagnetic lock 40, which includes a lock core 401 connected through a telescopic mechanism, and the lock core 401 can slide into the lock hole 391 driven by the telescopic mechanism, thereby locking the flange rotating disk 39 and preventing the double-sided seat cushion body 2 from rotating.

[0031] Furthermore, it also includes a wireless control module, which is electrically connected to a controller, and the controller is also electrically connected to the motor 35 , the Hall sensor 38 and the electromagnetic lock 40 .

[0032] Specifically, the electric bicycle is also provided with a control switch having the same effect as the controller. By pressing the controller or the control switch, the wireless control module controls the lock core 401 of the electromagnetic lock 40 to be retracted, and the lock core 401 is released from the flange rotating disk 39. Then the motor 35 is started, and the output shaft of the motor 35 rotates, driving the input shaft of the planetary reducer 36 to rotate. After a series of gear meshing transmissions inside the planetary reducer 36, the output shaft of the planetary reducer 36 is driven to rotate. The rotation of the output shaft of the planetary reducer 36 drives the connecting part 31 to rotate, thereby rotating the double-sided cushion body 2. Due to the flange The rotating disk 39, the connecting part 31 and the planetary reducer 36 are fixedly connected, so when the double-sided cushion body 2 rotates, these three components rotate together. When the flange rotating disk 39 rotates, the Hall sensor 38 senses the magnet 392 of the flange rotating disk 39. When the two magnets 392 rotate to the side corresponding to the Hall sensor 38, the Hall sensor 38 transmits the signal to the wireless control module, and the wireless control module controls the motor 35 to stop rotating. At the same time, the telescopic mechanism of the electromagnetic lock 40 is controlled to extend the lock core 401 into the lock hole 391, and the flange rotating disk 39 is locked, so that the double-sided cushion body 2 cannot rotate.

[0033] In the utility model, the double-sided seat cushion body 2 includes a seat cushion one and a seat cushion two, and the seat cushion one and the seat cushion two have the same structure and appearance. The connected end faces are provided with a groove 4, and a mounting seat 5 is provided in the groove 4. The mounting seat 5 is provided with a mounting groove 6. The connecting part 31 is provided with a clamping block 41 integrally formed therewith. The connecting part 31 and the clamping block 41 are cooperated and installed in the mounting groove 6. The connecting part 31 and the clamping block 41 can be glued to the mounting groove 6 by using a glue with a long service life and high temperature resistance, such as: glass glue. When the double-sided seat cushion body 2 is broken, it can be conveniently replaced. The installation of the double-sided seat cushion body 2 can also be made more secure by directly welding the connecting part 31 and the clamping block 41 to the mounting groove 6. Specifically, first install the connecting portion 31 and the snap-in block 41 into the mounting groove 6 of one of the double-sided seat cushion bodies 2, and then align the mounting groove 6 of the other double-sided seat cushion body 2 with the snap-in block 41 and insert it, and then fix the double-sided seat cushion bodies 2 together at the connecting gaps of the double-sided seat cushion bodies 2 by using glue or welding, so that the installation of the double-sided seat cushion bodies 2 can be completed.
