Description

Technical Field

[0001] This utility model belongs to the field of electric bicycle technology, specifically relating to an electric bicycle with a battery mounted on the seat adjustment lever. Background Technology

[0002] Electric bicycles, as a convenient and environmentally friendly mode of transportation, have gained widespread use in recent years. Their design typically includes an adjustable seat to accommodate users of different heights and riding habits. However, existing electric bicycle designs have some issues with the placement and method of battery installation. For example, the battery is usually installed at the bottom or rear of the frame, which not only increases the overall weight of the vehicle but may also lead to instability, affecting riding stability and safety.

[0003] In addition, the traditional method of installing electric bicycle batteries has some obvious drawbacks. First, the batteries are usually exposed to the outside and are easily damaged by dust, rain and external impacts, which reduces the battery's lifespan. Second, the process of removing and replacing batteries is relatively cumbersome and requires professional tools and skills, which brings inconvenience to users. Furthermore, the battery fixing method is not flexible enough and cannot be quickly adjusted according to the user's needs, which also limits the usage scenarios and user experience of electric bicycles.

[0033] In this embodiment, the height of the mounting plate body 64 is first adjusted by rotating the throttle 652 so that the battery body 63 can be smoothly installed on the lower terminal board 61. Then, the buffer assembly 66 is used to fix and buffer the battery body 63 to ensure that the battery is stable and reliable during use and will not be loosened or damaged due to bumps or external impacts.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that: the front housing fixing mechanism 7 includes a connecting plate 73, the connecting plate 73 is provided on the side of the front housing 5, the connecting plate 73 is provided on the side of the connecting plate 73, the upper end of the locking block 75 is provided with a fixing hole 74, the rear housing 3 is provided with a locking seat 72, the side of the locking seat 72 is provided with a locking groove 76, and the fixing component 71 is provided inside the locking seat 72.

[0036] By adopting the above technical solution, the front housing 5 and the rear housing 3 can be firmly fixed together through the cooperation of the card block 75 and the card slot 76, and the function of the fixing component 71. This enables the rapid assembly and disassembly of the front housing 5 and the rear housing 3, facilitates the maintenance and replacement of internal components such as the battery fixing mechanism 6, and improves the maintenance convenience and work efficiency of electric bicycles.

[0037] Specifically, the fixing component 71 includes a spring 714, the spring 714 is disposed inside the card holder 74, and a fixing rod 711 is disposed at the other end of the spring 714.

[0038] By adopting the above technical solution, when the card block 75 is inserted into the card slot 76, the fixing rod 711 can automatically be inserted into the fixing hole 74 under the elastic force of the spring 714, realizing the quick fixed connection between the front housing 5 and the rear housing 3. The operation is simple and convenient, and the connection is firm and reliable.

[0039] Specifically, the fixing component 71 also includes an adjusting block 712. The adjusting block 712 is provided on the side of the fixing rod 711, and the side of the card holder 72 is provided with an adjusting groove 713 corresponding to the adjusting block 712.

[0040] By adopting the above technical solution, when it is necessary to disassemble the front housing 5, the adjusting block 712 can be operated to move it along the adjusting groove 713, thereby driving the fixing rod 711 to exit from the fixing hole 74, realizing the quick disassembly of the front housing 5 and the rear housing 3, further improving the maintenance convenience and work efficiency of electric bicycles.

[0042] The working principle and usage process of this utility model are as follows: When using this utility model, firstly, the height of the mounting plate body 64 is adjusted by rotating the throttle 652 so that the battery body 63 can be smoothly installed on the lower terminal plate 61. Then, the battery body 63 is fixed and buffered by the buffer component 66. Next, by inserting the locking block 75 into the locking slot 76 and the fixing rod 711 being locked into the fixing hole 74 under the action of the spring 714, the front shell 5 and the rear shell 3 are fixedly connected together, realizing the protection and encapsulation of internal components such as the battery fixing mechanism 6. When it is necessary to maintain or replace the internal components, the fixing rod 711 is disengaged from the fixing hole 74 by operating the adjusting block 712, so that the front shell 5 can be quickly disassembled. This is convenient and quick, improving the efficiency of use and maintenance of electric bicycles.
