Description
Technical Field
[0001] This utility model relates to the field of bicycle frame technology, and more specifically, to an electric bicycle frame with a removable backup battery. Background Technology
[0002] Electric bicycles are a convenient mode of transportation that uses batteries as auxiliary power and is equipped with core components such as motors, controllers, frames, and batteries. They combine human riding with electric drive and are widely used in daily commuting and short-distance travel. The frame, as the core load-bearing structure, not only needs to support the weight of the bicycle and the rider, but also needs to provide stable installation space for components such as batteries.
[0003] In the existing technology, the battery installation and frame adaptation structure of electric bicycles has many shortcomings: 1. The battery needs to be installed inside the bicycle frame, which makes installation and disassembly inconvenient and cumbersome and time-consuming when replacing the battery or performing maintenance; 2. The battery mounting bracket has low universality. Most existing battery mounting brackets are designed with fixed size to match specific models of electric bicycle frames. When adapting to different models, corresponding mounting brackets need to be designed and manufactured separately, which greatly increases the production and use costs. Utility Model Content
[0004] The purpose of this invention is to provide an electric bicycle frame with a removable backup battery to solve the problems mentioned in the background art.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: An electric bicycle frame with a removable backup battery includes a mounting bracket. The inner wall of the mounting bracket has guide grooves symmetrically distributed about the mounting bracket. A battery assembly is disposed on the inner wall of the guide grooves. Positioning blocks symmetrically distributed about the mounting bracket are fixedly connected to the side wall of the mounting bracket. A cover plate is slidably connected to each positioning block via a positioning groove. Buckles symmetrically distributed about the cover plate are fixedly connected to the side wall of the cover plate. Air inlet pipes symmetrically distributed about the cover plate are also fixedly connected to the side wall of the cover plate. Limiting components symmetrically distributed about the mounting bracket are disposed on the side wall of the mounting bracket. The mounting bracket is connected to the frame body via clamping components symmetrically distributed about the mounting bracket.
[0006] As a preferred technical solution of this application, the battery assembly includes a guide plate slidably connected to the inner wall of the guide groove, a battery shell fixedly connected to the side wall of the guide plate, a uniformly distributed partition plate fixedly connected to the inner wall of the battery shell, and wire holes opened on the outer wall of the partition plate.
[0007] As a preferred technical solution of this application, the limiting component includes a fixed shell fixedly connected to the side wall of the mounting bracket, and the fixed shell is slidably connected to the buckle. A limiting plate is slidably connected to the outer wall of the fixed shell, and the inner wall of the limiting plate abuts against the outer wall of the buckle. A uniformly distributed strong tension spring is fixedly connected to the outer wall of the limiting plate, and the strong tension spring is fixedly connected to the mounting bracket.
[0008] As a preferred technical solution of this application, the clamping assembly includes an adjusting screw threaded to the side wall of the mounting bracket, a clamping plate rotatably connected to the outer wall of the adjusting screw, and the side wall of the clamping plate abutting against the outer wall of the vehicle frame body. A hexagonal drive block is fixedly connected to the end of the adjusting screw away from the clamping plate.
[0009] As a preferred technical solution of this application, the side wall of the mounting frame is fixedly connected with air outlet pipes that are symmetrically distributed about the mounting frame, and the air outlet pipes and air inlet pipes cooperate with each other.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. The battery assembly can be quickly disassembled and installed by sliding the guide plate and guide groove, which facilitates the replacement of the spare battery. The cover is quickly positioned by the positioning groove and positioning block. It can be released by simply pulling the limit plate, which greatly shortens the disassembly and assembly time during battery maintenance. It solves the problem that the battery is installed in the frame, which makes disassembly and assembly inconvenient and the replacement and maintenance operations are cumbersome and time-consuming in the existing technology. 2. The adjustable screw allows for the movement of the clamping plate, accommodating different frame sizes and enabling the mounting bracket to match various electric bicycle frames. This eliminates the need for separate mounting bracket designs for different models, reducing usage and production costs. Simultaneously, the heat dissipation structure composed of the air inlet and outlet pipes effectively dissipates battery heat, preventing battery aging due to high temperatures. The connection point at the top ensures ventilation while preventing water from entering the battery casing, reducing the risk of short circuits and extending battery life. This addresses the issues of low versatility in existing battery mounting brackets, which are designed to be fixed-size and only fit specific models, requiring separate production and increasing costs.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0014] like Figure 1-6 As shown, the electric bicycle frame with a removable spare battery includes a mounting frame 1. The inner wall of the mounting frame 1 has guide grooves 6 symmetrically distributed about the mounting frame 1. A battery assembly is disposed on the inner wall of the guide grooves 6. Positioning blocks 10 symmetrically distributed about the mounting frame 1 are fixedly connected to the side wall of the mounting frame 1. A cover plate 11 is slidably connected to the positioning blocks 10 through positioning grooves 12. Buckles 13 symmetrically distributed about the cover plate 11 are fixedly connected to the side wall of the cover plate 11. The buckles 13 realize the connection between the cover plate 11 and the limiting components, which is convenient and quick and reduces installation time. An air inlet pipe 17 symmetrically distributed about the cover plate 11 is also fixedly connected to the side wall of the cover plate 11. Limiting components symmetrically distributed about the mounting frame 1 are disposed on the side wall of the mounting frame 1. The frame body 5 is connected to the mounting frame 1 through clamping components symmetrically distributed about the mounting frame 1.
[0015] In this embodiment, like Figure 4-5As shown, the battery assembly includes a guide plate 7 slidably connected to the inner wall of the guide groove 6. A battery case 8 is fixedly connected to the side wall of the guide plate 7. Evenly distributed partitions 9 are fixedly connected to the inner wall of the battery case 8. A wire hole 19 is opened on the outer wall of the partition 9. By aligning the guide plate 7 on the side wall of the battery case 8 with the guide groove 6 on the inner wall of the mounting frame 1, and pushing the battery case 8 to make the guide plate 7 slide along the guide groove 6, the battery assembly can be installed into the mounting frame 1. By pulling the battery case 8 in the opposite direction, the guide plate 7 slides out along the guide groove 6, realizing the quick removal of the battery assembly. The partitions 9 inside the battery case 8 separate different batteries. The wire hole 19 is used for the threading and organization of battery wires. The cover plate 11 can be used to install cable connectors for connecting battery wires to power the electric bicycle.
[0016] like Figure 5-6 As shown, the limiting assembly includes a fixed housing 14 fixedly connected to the side wall of the mounting bracket 1, and the fixed housing 14 is slidably connected to the buckle 13. A limiting plate 15 is slidably connected to the outer wall of the fixed housing 14, and the inner wall of the limiting plate 15 abuts against the outer wall of the buckle 13. A uniformly distributed strong tension spring 16 is fixedly connected to the outer wall of the limiting plate 15, and the strong tension spring 16 is fixedly connected to the mounting bracket 1. When the positioning groove 12 on the cover plate 11 is aligned with the positioning block 10 of the mounting bracket 1, the cover plate 11 is pushed so that the buckle 13 slides into the fixed housing 14. At this time, the strong tension spring 16 is in its natural state, which causes the limiting plate 15 to abut against the outer wall of the buckle 13, thus completing the fixing of the cover plate 11. When the cover plate 11 needs to be removed, the limiting plate 15 is pulled and the strong tension spring 16 is pulled to extend, releasing the limiting of the buckle 13, and the cover plate 11 can be pulled out in the opposite direction.
[0017] like Figure 1-3 As shown, the clamping assembly includes an adjusting screw 2 threaded to the side wall of the mounting bracket 1. A clamping plate 3 is rotatably connected to the outer wall of the adjusting screw 2, and the side wall of the clamping plate 3 abuts against the outer wall of the frame body 5. A hexagonal drive block 4 is fixedly connected to the end of the adjusting screw 2 away from the clamping plate 3. Rotating the hexagonal drive block 4 causes the adjusting screw 2 to rotate, and the adjusting screw 2 pushes the clamping plate 3 to move along the side wall of the mounting bracket 1 until the clamping plate 3 abuts tightly against the outer wall of the frame body 5, thus completing the fixing of the mounting bracket 1 to the frame body 5 of different sizes.
[0018] To further explain, such as Figure 2 As shown, the side wall of the mounting bracket 1 is fixedly connected with air outlet pipes 18 that are symmetrically distributed about the mounting bracket 1, and the air outlet pipes 18 and the air inlet pipes 17 cooperate with each other. When the electric bicycle is working and the vehicle is moving, air enters the interior of the mounting bracket 1 along the air inlet pipes 17 on the cover plate 11. When it flows through the battery assembly, it carries away the heat generated by the battery operation. Finally, the hot air is discharged from the air outlet pipes 18 on the side wall of the mounting bracket 1. Since the connection points of the air inlet pipes 17, the air outlet pipes 18 and the mounting bracket 1 are all located at the upper end, water stains can be prevented from entering the battery case 8 from the ventilation opening when riding.
[0019] When using this electric bicycle frame with a removable spare battery: Rotating the hexagonal drive block 4 rotates the adjusting screw 2, which in turn pushes the clamping plate 3 along the side wall of the mounting bracket 1 until the clamping plate 3 is tightly against the outer wall of the frame body 5, thus securing the mounting bracket 1 to the frame body 5 of different sizes. Align the guide plate 7 on the side wall of the battery case 8 with the guide groove 6 on the inner wall of the mounting bracket 1, and push the battery case 8 to slide the guide plate 7 along the guide groove 6. This allows the battery assembly to be installed into the mounting bracket 1. Pulling the battery case 8 in the opposite direction causes the guide plate 7 to slide out along the guide groove 6, enabling quick removal of the battery assembly. The partition 9 inside the battery case 8 separates different batteries, and the wire hole 19 is used for threading and organizing battery wiring. Align the positioning groove 12 on the cover plate 11 with the mounting bracket 1. The positioning block 10 pushes the cover plate 11 to make the buckle 13 slide into the fixed shell 14. At this time, the strong tension spring 16 is in the natural state, which drives the limiting plate 15 to abut against the outer wall of the buckle 13, thus completing the fixation of the cover plate 11. When the cover plate 11 needs to be removed, pull the limiting plate 15 and pull the strong tension spring 16 to extend, release the limit on the buckle 13, and then pull the cover plate 11 out in the opposite direction. When the electric bicycle is working and the vehicle is moving, the air enters the interior of the mounting bracket 1 along the air inlet pipe 17 on the cover plate 11. When it flows through the battery assembly, it carries away the heat generated by the battery operation. Finally, the hot air is discharged from the air outlet pipe 18 on the side wall of the mounting bracket 1. Since the connection points of the air inlet pipe 17, the air outlet pipe 18 and the mounting bracket 1 are all located at the upper end, it can prevent water stains from entering the battery shell 8 from the ventilation port when riding.
