[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0020] Please see Figures 1-4 In this embodiment of the utility model, a folding bicycle with detachable design includes a frame front body 1 and a rear wheel set balance kit 2; a battery compartment 4 is fixedly provided on the lower side of the frame front body 1, and a battery slot corresponding to a storage battery 5 is provided inside the battery compartment 4. The storage battery 5 is placed in the battery slot, and an upper rotary switch 9 and a lower rotary switch 10 are respectively provided on the upper and lower sides of the battery slot.
[0021] The storage battery 5 is a lithium-ion battery;
[0022] A connecting rod 3 is provided on the lower right side of the front body 1 of the frame, and a socket corresponding to the pin 6 is provided on the connecting rod 3;
[0023] The rear wheel balancing kit 2 is equipped with a storage basket 8. The lower end of the rear wheel balancing kit 2 has two wheels, each with a mudguard. The rear wheel balancing kit 2 adopts an auxiliary anti-tilt mechanism designed with a double wishbone linkage principle, mainly composed of eight linkages, two springs, and several hardware parts. When riding and turning, the center of gravity of the whole vehicle will shift to the left (or right). At this time, the rear wheel balancing kit will apply a counterforce to center the center of gravity and correct the rider's position, preventing the rider from tilting excessively.
[0024] The rear wheel assembly balance kit 2 has a connecting rod 7 corresponding to the connecting rod 3 on its left front side. The connecting rod 3 has a socket 11 inside, and one end of the connecting rod 7 has a plug 12 corresponding to the socket 11. The plug 12 has a second socket corresponding to the first socket. The plug 12 is inserted into the socket 11 of the connecting rod 3, and the plug 12 and the connecting rod 3 are fixedly connected by a pin 6. The pin 6 is inserted into the first socket and the second socket. A movable pin is provided above the pin 6. Example
[0025] Please see Figures 2-5 The difference between this embodiment and Embodiment 1 is that the rear wheel assembly balance kit 2 is replaced with a rear wheel assembly single wheel kit 13, which includes a rear wheel assembly single wheel kit 13. The lower end of the rear wheel assembly single wheel kit 13 is provided with a wheel, a mudguard is provided on the wheel, and auxiliary wheels are provided on both sides of the wheel. Example
[0026] Please see Figures 2-4 6. The difference between this embodiment and Embodiment 1 is that the rear wheel assembly balance kit 2 is replaced with a rear wheel assembly dual-wheel kit 14, which includes a rear wheel assembly dual-wheel kit 14 with two wheels at the lower end, each wheel having a mudguard; and a standing plate is provided between the two wheels.
[0027] Disassembly steps: First, press down on the movable pin above the pin 6 with your finger and hold it down. Then, pull the entire pin outward until it is completely detached from the connecting rod 3. At the detached position, hold the front body 1 of the frame with your left hand and the rear wheel assembly balance kit 2 with your right hand and pull it outward until it is completely detached. The above steps complete the disassembly of the vehicle body.
[0028] Body assembly steps: At the tight position, hold the front body 1 of the frame with your left hand and the rear wheel assembly balance kit 2 with your right hand, and insert it back along the inward direction to insert the connecting rod 7 into the connecting rod 3 until the two parts are completely close together; then, first press down the movable pin located above the pin with your finger and hold it, then insert the entire pin into the body along the inward direction and release the pin until it is locked.
[0029] When removing the battery, first pinch the upper rotary switch 9 and the lower rotary switch 10 located at the top and bottom of the battery compartment with two fingers and rotate them 90 degrees (note that at this time the upper rotary switch 9 and the lower rotary switch 10 are parallel to the side of the battery compartment). Then, grab the top of the battery and use the pry handles on both sides to remove it vertically until the battery is removed from the battery compartment.
[0030] When installing the battery, first grasp the top of the battery with your hand, then insert it vertically along the inside of the battery compartment. After it is fully inserted, pinch the upper rotary switch 9 and the lower rotary switch 10 located at the top and bottom of the battery compartment with two fingers and rotate them 90 degrees (note that at this time the upper rotary switch 9 and the lower rotary switch 10 are perpendicular to the side of the battery compartment) until the battery is firmly attached to the battery slot.
[0031] The folding bicycle of this application improves user convenience. When the battery life decreases, consumers can replace the battery themselves, saving time and costs. It also enhances the user experience, making it easier to operate, more user-friendly, and more multifunctional. It is easy and quick to assemble and disassemble, making it easier to carry and maintain, and convenient for users to travel short distances and enjoy leisure activities.
[0032] 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.
