Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, specifically to a quick battery replacement structure for electric bicycles. Background Technology

[0002] E-bikes are a new type of transportation that blends traditional bicycles with modern technology. While retaining the basic riding structure of a bicycle, they are equipped with an electric drive system. When the rider pedals, the motor provides auxiliary power, reducing the burden of riding and making it easier. E-bikes are suitable for daily commutes, allowing for quick travel through city streets, saving time and energy; they are also suitable for leisurely riding, satisfying people's need to explore nature. Their range is sufficient for certain distances, and compared to cars, they are more environmentally friendly, also offering fitness benefits, and are gradually becoming a popular green travel option. The battery of an e-bike is generally cylindrical and installed inside a built-in mounting cylinder. Therefore, when replacing the battery, it is inconvenient to directly remove it because it is located inside the mounting cylinder. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a structure for quick battery replacement in electric bicycles.

[0004] The present invention adopts the following technical solution:

[0005] A quick-change structure for a power-assisted bicycle battery includes a fixed outer shell. A groove is formed on the inner wall of the fixed outer shell. A mounting plate is fixedly connected to the bottom of the inner wall of the fixed outer shell. A return spring is fixedly connected to the top of the mounting plate. A connecting plate is fixedly connected to the top of the return spring. A bearing is installed inside the connecting plate. A rotating column is rotatably connected inside the bearing. A limit plate is fixedly connected to the top of the rotating column. A slider is fixedly connected to the surface of the connecting plate. A limit platform is engaged with the surface of the limit plate. A battery body is fixedly connected to the top of the limit platform. A limit groove is engaged with the bottom of the limit platform. A limit plate and a positioning plate are fixedly connected to the inner wall of the fixed outer shell.

[0006] The fixed outer shell provides overall structural support, the inner wall grooves guide the sliding of other components, the mounting plate is used to fix the return spring, which can provide a certain elastic buffer and reset function during battery installation or removal, the connecting plate is used to connect other components, the cooperation of the bearing and the rotating column allows the limit plate to rotate flexibly, the snap-fit ​​structure between the limit plate and the limit plate stage is used to fix the battery body, the slider ensures the stable sliding of the connecting plate within the fixed outer shell, the limit groove further fixes the limit plate stage, and the limit plate and positioning plate play a role in limiting and positioning the battery installation position.

[0007] In a further improvement, the number of the slide grooves is set to two, and the two slide grooves are symmetrically and evenly distributed around the top center of the fixed housing, and the slider is slidably connected inside the slide groove.

[0008] The two sliding grooves, symmetrically and evenly distributed around the top center of the fixed housing, allow the slider to slide more stably, thus ensuring the smooth movement of the components connected to the slider and facilitating rapid battery replacement.

[0009] In a further improvement, the number of mounting plates is set to four, and the four mounting plates are arranged in a circle to fix the bottom of the outer shell, and the limiting plate is engaged inside the limiting groove.

[0010] Four mounting plates, arranged circumferentially to secure the bottom of the casing, provide more even support for components such as the return spring, resulting in more uniform stress distribution throughout the structure. Limiting plates engage within the limiting slots to securely hold the battery, preventing it from shifting or moving during use.

[0011] In a further improvement, the limiting plate is located above the connecting plate.

[0012] The limiting plate is located above the connecting plate. This layout allows the limiting plate to better cooperate with components such as the limiting plate platform. During battery installation or removal, the limiting plate can effectively perform the function of locking and fixing.

[0013] In a further improvement, the number of limiting plates is set to two, and the two limiting plates are evenly distributed on the inner wall symmetrically with respect to the top center of the fixed outer shell, and the limiting plates are located below the connecting plate.

[0014] Two limiting plates are symmetrically and evenly distributed on the inner wall around the center of the top of the fixed shell. They can effectively restrict the relevant components during the battery installation process from below, preventing excessive movement of the components. Furthermore, since they are located below the connecting plate, they can assist other components in accurately positioning and fixing the battery.

[0015] In a further improvement, a cover is hinged to the surface of the fixed outer shell, and an inner cover is fixedly connected to the surface of the cover. A through hole is provided on the top of the inner cover.

[0016] The hinged cover on the fixed outer shell makes it easy to open and close, facilitating battery replacement, while the inner cover can protect the internal structure to some extent.

[0017] In a further improvement, the through hole extends through both the upper and lower ends of the cap.

[0018] The beneficial effects of this utility model are:

[0019] In this invention, pressing the battery body disengages the top of the limiting bracket from the bottom of the limiting plate. Rotating the battery body disengages the limiting bracket from below the limiting plate. Releasing the pressure on the battery body allows the connecting plate to return to the top of the limiting plate under the action of the return spring, thus allowing the battery body to be pulled out from the inside of the fixed housing. This facilitates the removal and fixing of the battery in the electric bicycle. Simultaneously, the cooperation between the spring and the connecting plate provides some cushioning for the battery body. When the connecting plate moves downwards, the slider moves inside the groove, making the connecting plate more stable during downward movement and preventing the battery body from shifting during installation.

Then press down on the battery body 11, and the connecting plate 5 is located below the limiting plate 13. Rotate the battery body 11 to rotate the limiting plate 10 to the bottom of the limiting plate 13. The surface of the limiting plate 10 contacts the surface of the positioning plate 14. Release the force of pressing the battery body 11, and the limiting plate 10 contacts the bottom of the limiting plate 13 under the action of the return spring 4, thus engaging the battery body 11 inside the fixed housing 1.

[0033] When quickly removing the battery of the electric bicycle, press the battery body 11, causing the top of the limiting plate 10 to disengage from the bottom of the limiting plate 13. Rotate the battery body 11 so that the limiting plate 10 disengages from below the limiting plate 13. Release the force of pressing the battery body 11, and under the action of the return spring 4, the connecting plate 5 returns to above the limiting plate 13, so that the battery body 11 can be pulled out from the inside of the fixed housing 1.
