[0002] In modern society, bicycles are not only an important means of transportation but also a popular leisure activity and fitness method, widely used in transportation, entertainment, and sports. Electric bicycles are mechatronic personal transportation tools that combine the features of a traditional bicycle and an electric motor. Powered by an onboard battery, they are two-wheeled bicycles that provide electric drive or electric assistance, reducing the rider's physical exertion. Electric bicycles typically include components such as a motor, battery, controller, handlebars, and brakes to provide either full electric drive or riding assistance. However, the batteries in existing electric bicycles are simply placed inside the vehicle. Due to their light weight and small size, they are easily removed and stolen by strangers, leading to frequent battery theft, unnecessary inconvenience for the owner, and reduced battery safety.

[0013] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0014] The present invention will now be described in detail with reference to the accompanying drawings.

[0015] like Figure 1 As shown, this utility model discloses a compact electric bicycle, including a vehicle body 1, a seat 2 disposed on the vehicle body 1, and a battery 3 detachably disposed on the vehicle body 1. The battery 3 is provided with a housing 31, a telescopic member 32 is provided on one side of the housing 31, a key 33 is provided on the telescopic member 32, and a locking tongue 34 is provided on the other side of the housing 31. The vehicle body 1 is provided with a positioning plate 11, and the positioning plate 11 is provided with a positioning hole 12. The locking tongue 34 is accommodated in the positioning hole 12.

[0016] The locking tongue 34 is preferably a battery pack-specific locking tongue, which is existing technology. The locking tongue is embedded inside the battery box, working with an elastic element and a transmission rod to secure or release the battery pack. The owner inserts the key 33 into the telescopic member 32 and applies force to compress it inward. Since the telescopic member 32 is perpendicular to the transmission rod, which is connected to the locking tongue 34, when force is applied to compress the telescopic member 32, it moves closer to and against the transmission rod, pushing it. This causes the telescopic member 32 to push the locking tongue 34 through the transmission rod, allowing the locking tongue 34 to protrude into the positioning hole 12. The elastic element is located between the transmission rod and the outer casing 31. When released... When the telescopic component 32 is extended, the elastic force of the elastic element resets the transmission rod. Two moving channels are provided inside the outer casing 31, perpendicular to each other. This allows the telescopic component 32 to move along one channel and the transmission rod along the other, thus fixing the battery 3 within the vehicle body 1 and preventing theft. The telescopic component 32, locking tongue 34, elastic element, and transmission rod are all housed within the outer casing 31, while the battery 3 is fixedly connected within it. The seat 2 is flip-up, rotating around the axis of the vehicle body 1. Flipping the seat 2 upwards facilitates the removal of the outer casing 31. This invention features a compact and rationally designed structure. The locking tongue 34, housed within the positioning hole 12, ensures the battery 3 is securely and stably held within the vehicle body 1, providing high anti-theft performance and enhancing battery safety.

[0017] In this embodiment, the vehicle body 1 is provided with a housing frame 13 and a housing seat 14 that cooperates with the housing frame 13. The outer shell 31 passes through the housing frame 13 so that the outer shell 31 is housed in the housing seat 14. Specifically, the housing frame 13 and the housing seat 14 are arranged vertically at intervals. The outer shell 31 passes through the housing frame 13 so that the outer shell 31 is housed in the housing seat 14. This allows the housing frame 13 to position the middle of the battery 3, and the housing seat 14 to position the bottom of the battery 3. By providing a dual positioning function for the battery 3, the position of the battery 3 on the vehicle body 1 is further fixed, enhancing the positioning function.

[0018] In this embodiment, a handle 35 is rotatably connected to the top of the battery 3. Specifically, the handle 35 can be flipped upwards to easily pull the battery 3 out of the housing 13 and the housing 14 for quick and easy removal, while the handle 35 can be flipped downwards to easily store the handle 35 on top of the battery 3, preventing the handle 35 from obstructing or interfering with the use of the seat 2.

[0019] In this embodiment, the vehicle body 1 is equipped with a rear tire 4. A mounting bracket 5 is located at one end of the vehicle body 1 near the rear tire 4. A motor 6 is mounted on the mounting bracket 5. The motor 6 is driven and connected to the rear tire 4, and is electrically connected to the battery 3. Specifically, the motor 6 can be a DC motor or a brushless motor. Brushless motors are the preferred choice due to their high efficiency, low maintenance, and long lifespan. The brushless motor 6 uses an electronic commutator for commutation, eliminating the need for a mechanical commutator, resulting in quieter and more efficient operation. Furthermore, brushless motors offer better control performance, providing more precise speed and torque control. The motor 6 is mounted and fixed on the mounting bracket 5, and is driven and connected to the rear tire 4. The motor 6 is electrically connected to the battery 3, which provides effective power to the motor 6. The motor 6 provides sufficient driving force to rotate the rear tire 4, thereby moving the entire vehicle body 1.

[0020] In this embodiment, the vehicle body 1 is rotatably equipped with a handlebar 7 and a front fork 8. The front fork 8 is equipped with a front tire 9, and the handlebar 7 is connected to the front tire 9 through the front fork 8. Specifically, the handlebar 7 drives the front fork 8 to swing left and right relative to the vehicle body 1, so that the handlebar 7 is connected to the front tire 9 through the front fork 8, thereby improving the handling performance of the front tire 9.
