Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and in particular to a rack assembly structure for an electric bicycle. Background Technology

[0002] Low-carbon travel is becoming the choice of more and more people. Among them, electric bicycles, as a green, energy-saving and emission-reducing means of transportation, have received widespread attention in the field of short-distance urban travel, and their role in reducing carbon emissions and alleviating traffic pressure is becoming increasingly prominent.

[0003] By adding components such as a battery, controller, electric hub, and speed controller to a traditional bicycle, it can be converted into an electric-assist bicycle. However, this type of modification has many inconveniences: operators usually install the battery box containing the battery on the rear rack of the bicycle, which occupies the rack space, losing the original carrying function, resulting in low space utilization and overall structural redundancy. In addition, the battery and controller are often assembled separately, and the connecting wires between the battery and controller are often exposed, which not only affects the aesthetics but is also susceptible to damage from external environmental factors (such as collisions and friction), thus affecting the safety and lifespan of the battery.

[0004] Therefore, there is an urgent need for a rack assembly structure for electric bicycles to solve the above problems. Utility Model Content

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 4As shown, this embodiment provides a rack assembly structure for an electric bicycle. This rack assembly structure includes a rack body 100 and an electrical interface. The rack body 100 has an installation space and a loading / unloading port communicating with the installation space. The electric bicycle includes a battery pack 200, which is disposed within the installation space and supported by the rack body 100. The electrical interface is also disposed within the installation space and is used to electrically connect with a mating interface on the battery pack 200 when the battery pack 200 is inserted into the installation space. This design achieves a high degree of integration between the battery pack 200 and the rack body 100, completely concealing the battery pack 200 within the rack body 100, effectively improving space utilization and resulting in a simpler, more streamlined appearance, enhancing its aesthetics. Simultaneously, the battery module, as part of the rack body 100, shares the load with it, providing power while further enhancing the overall structural integrity and improving the safety and lifespan of the battery pack 200.

[0034] It should be noted that the battery pack 200 in this embodiment can be equipped with 375Wh and 500Wh battery systems.

[0035] Optionally, the access port is located on the side of the shelf body 100, and the installation space is a cavity extending vertically. The battery pack 200 can pass through the access port horizontally and be detachably fixed to the cavity. This arrangement ensures ease of disassembly and assembly by providing the access port on the side of the shelf body 100, without affecting the normal use of the top of the shelf body 100. At the same time, the horizontal pull-out design allows the battery pack 200 to be disassembled and assembled without lifting it forcefully, making the operation very labor-saving and convenient. Even when there are items on the shelf (as long as they do not obstruct the pull-out path), the battery pack 200 can be easily accessed and placed. This modular design clearly defines the battery pack 200 as an independent, quickly replaceable functional module, facilitating subsequent replacement, upgrades, or maintenance of the battery pack 200 by operators.

[0036] Specifically, this embodiment provides the following exemplary technical solution: The shelf body 100 includes a support platform 1, a support frame 2, and a connecting frame. The support platform 1 and the support frame 2 are spaced apart in the vertical direction to form an installation space. The battery pack 200 is supported on the support frame 2, and the connecting frame is fixedly connected between the support platform 1 and the support frame 2. This configuration design makes the battery module a solid base for the entire shelf system, and the vertically arranged battery pack 200 further lowers the center of gravity of the entire vehicle, achieving structural and functional integration and improving the stability and handling of the electric bicycle when riding and stationary.

[0037] Optionally, in order to ensure precise guidance and secure locking of the battery pack 200 during insertion to prevent shaking and abnormal noise during riding, the battery pack 200 is provided with guide structures and locking structures on both sides that match the shape of the support frame 2.

[0038] In this embodiment, the connecting frame includes two first connecting rods 3 and two second connecting rods 4. The two first connecting rods 3 are fixedly connected to the bearing platform 1 and the support frame 2, and the support frame 2 is located between the two first connecting rods 3. The two second connecting rods 4 are simultaneously fixedly connected to the bearing platform 1, the support frame 2 and the first connecting rods 3, and the support frame 2 is located between the two second connecting rods 4.

[0039] Optionally, in order to further improve the support stability and reliability of the rack body 100, the rack assembly structure of the electric bicycle also includes a first fixed frame 5 and a second fixed frame 6. The first fixed frame 5 is fixedly connected to the first connecting rod 3 and the second connecting rod 4 on both sides, and the second fixed frame 6 is fixedly connected to the first connecting rod 3 and the second connecting rod 4 on both sides.

[0040] Optionally, the electric bicycle also includes a taillight 7, which is integrated into the rack body 100 and electrically connected to an electrical interface, and powered by a battery pack 200. This configuration directly utilizes the power of the battery pack 200 to power the taillight 7 (or brake light) integrated into the rack body 100, eliminating the need for separate batteries or wiring for the light fixture and improving the simplicity and aesthetics of the wiring.

[0041] Optionally, the battery pack 200 includes a battery casing and a battery module. The battery casing has a receiving cavity inside, in which the battery module is housed. The receiving cavity is provided with a partition structure to divide the receiving cavity into several compartments. Further, the several compartments may include a main compartment for housing the battery module and auxiliary compartments for housing wiring harnesses, controllers, or tools. This arrangement maximizes space utilization and functional integration. It further utilizes the three-dimensional space inside the battery casing, dividing it into compartments with different functions. This not only houses the battery module itself but also hides and stores other electronic devices (such as controllers) or tools of the electric bicycle, making the overall layout more compact and neat. At the same time, the independent wiring harness compartment can also organize and protect power and signal cables, preventing cable tangling and wear, and improving the safety and reliability of the system.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
