Abstract
Description
Technical Field
[0001] This invention relates to the field of lithium battery technology, and in particular to a lithium battery for two-wheeled vehicles that is easy to disassemble. Background Technology
[0002] With urbanization and increased environmental awareness, electric two-wheelers (such as electric bicycles and electric motorcycles) are widely used around the world due to their green and convenient characteristics, especially in the Asian market where they are growing rapidly. As the core power source, the performance of the power battery directly affects the vehicle's range, safety, lifespan, and user experience.
[0003] Currently, two-wheeled vehicle batteries mainly use lead-acid batteries and lithium-ion batteries. Although lead-acid batteries are low in cost and have mature technology, they have problems such as low energy density, heavy weight, short lifespan, and slow charging, which makes it difficult to meet users' needs for high performance and lightweight design.
[0004] In contrast, lithium-ion batteries have become the mainstream choice due to their advantages such as high energy density, lightweight, long life and low self-discharge. Common types include ternary lithium (NCM), lithium iron phosphate (LFP) and lithium manganese oxide (LMO). Especially for high-power vehicles such as electric motorcycles, they are usually equipped with lithium battery packs with larger capacity and higher voltage, and are generally installed vertically inside the vehicle body.
[0005] However, existing lithium batteries have significant problems in practical applications: poor anti-theft performance. Since most battery compartments are only secured by seat latches, they are easy to disassemble. When parked outdoors, the entire high-value battery can be easily pried away in a short time, causing property loss to users and seriously affecting their sense of security. Summary of the Invention
[0006] To address the problems mentioned in the background section, the present invention provides a conveniently detachable lithium battery for two-wheeled vehicles.
[0007] The technical solution of the present invention is as follows: a lithium battery for two-wheeled vehicles that is easy to disassemble, comprising a housing, a cover plate fixedly connected to the upper side of the housing, a noise alarm installed inside the housing, a fixed shell fixedly connected inside the housing, battery packs placed on both sides of the fixed shell inside the housing, a first handle slidably connected to the fixed shell, an assistive component for easy disassembly of the housing installed inside the fixed shell, symmetrically distributed second spring telescopic rods fixedly connected to the housing, a sliding seat fixedly connected to the telescopic part of the second spring telescopic rods and in contact with both the housing and the cover plate, and a second handle rotatably connected to the sliding seat.
[0008] Preferably, the assistive component includes symmetrically distributed baffles, which are rotatably connected to both sides of the first handle. The first handle is provided with spring plates that are fixedly connected to the symmetrically distributed baffles. A first spring telescopic rod is fixedly connected inside the fixed housing. The telescopic part of the first spring telescopic rod is fixedly connected to the first handle. The first handle is hinged to two hinge rods located inside the fixed housing. Each of the two hinge rods has a hinge frame hinged to its lower side. The fixed housing is provided with an outlet for the two hinge frames to extend out. The two hinge frames are hinged to each other and rotatably connected to the fixed housing.
[0009] Preferably, the symmetrically distributed baffles are located in the middle of the cover plate, and all the symmetrically distributed baffles are located in the middle of the symmetrically distributed sliding seats.
[0010] Preferably, the device also includes two symmetrically distributed limiting components, each disposed within the housing. Each limiting component corresponds to a sliding seat and is used to restrict the position of the housing within the two-wheeled vehicle. Each limiting component includes a pressing plate slidably connected within the housing and slidably connected to a sliding shell. Inclined surfaces are provided on the opposing sides of both the pressing plate and the sliding shell. Symmetrically distributed triggering components are disposed within the housing, each corresponding to a sliding seat and used to press against adjacent pressing plates.
[0011] Preferably, the side of the sliding shell away from the extrusion plate has a rough surface.
[0012] Preferably, both the sliding shell and the extrusion plate are located in the lower part of the shell.
[0013] Preferably, the triggering component includes two symmetrically distributed sliding frames, both of which are slidably connected to the housing. An elastic element is fixed between the back side of each symmetrically distributed sliding frame and the housing. An elastic plate located inside the housing is disposed between the symmetrically distributed sliding frames, and the elastic plate is used to compress the adjacent compression plate.
[0014] Preferably, each of the symmetrically distributed sliding frames is hinged with a hinge plate, and the hinge plates are hinged to each other to abut against the elastic plate. The sliding seat is fixed with symmetrically distributed sliding rods, and the symmetrically distributed sliding rods slide along the housing. Each sliding rod corresponds to a sliding frame and is used to limit the sliding frame. Each symmetrically distributed sliding frame has a pulling member fixed to its opposite side inside the housing.
[0015] Preferably, the elastic plate is arc-shaped, and the hinged plates that are hinged to each other are V-shaped.
[0016] Preferably, the sliding frame is provided with a serrated portion, and an elastic limiting frame corresponding to the serrated portion is fixedly connected inside the housing. The elastic limiting frame is used to lock the serrated portion.
[0017] This invention has the following advantages: This device proposes an anti-theft mechanism that induces thieves to accidentally touch the wrong switch to trigger an alarm. When a thief attempts to remove the battery, they will accidentally activate a "fake handle" disguised as a conventional fixed structure, thereby pulling the second spring telescopic rod. The telescopic part of the rod produces a sound during the pulling process, which is monitored and identified in real time by a noise alarm, immediately activating a buzzer alarm. Simultaneously, the spring telescopic rod continues to extend, creating abnormal visual and tactile feedback, leading the thief to mistakenly believe it is "getting longer and longer and cannot be pulled out," causing psychological pressure and enhancing deterrence. The device effectively delays or prevents theft. When it needs to be dismantled, moving the first handle triggers the relative rotation of the two hinged frames, causing them to lift the device and provide assistance while facilitating dismantling. When the sliding seat is pulled by the thief, it moves the housing upward. At this time, the pressing plate and the sliding housing move relative to each other. Under the guidance of their inclined surfaces, the friction between the sliding housing and the two-wheeled vehicle is increased, thus achieving a "tighter the pull" mechanical self-locking effect, increasing the difficulty of dismantling and preventing the device from being quickly stolen.

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0021] To address the issues of poor anti-theft performance of existing lithium batteries, the reliance on seat pad locks for battery compartments which are easily disassembled, and the potential for high-value batteries to be quickly pried away when parked outdoors, resulting in property loss and affecting user safety, this device is described below.
[0022] Example 1
[0023] A type of easily detachable lithium battery for two-wheeled vehicles, such as Figures 1-6 As shown, the device includes a housing 1, a cover plate 2 fixedly attached to the upper side of the housing 1, a noise alarm installed inside the housing 1, a fixed shell 3 fixedly attached inside the housing 1, battery packs placed on both sides of the fixed shell 3 inside the housing 1, a first handle 4 slidably connected to the fixed shell 3, an assistive component for easy disassembly of the housing 1 inside the fixed shell 3, symmetrically distributed second spring telescopic rods 7 fixedly attached to the housing 1, a sliding seat 5 fixedly attached to the telescopic part of the second spring telescopic rod 7 that contacts both the housing 1 and the cover plate 2, a second handle 6 rotatably connected to the sliding seat 5, and a noise-generating coating that can be applied to the telescopic part of the second spring telescopic rod 7. When the telescopic part of the second spring telescopic rod 7 is pulled out, the noise triggers the noise alarm inside the housing 1. Figure 3 The upper side inside the middle casing 1 will then emit a beeping sound, firstly to remind the user that they have accidentally touched the wrong position, and secondly to emit a piercing sound when the device is stolen from the battery, to alert the surrounding people.
[0024] like Figure 5 and Figure 6As shown, the power assist assembly includes symmetrically distributed baffles 401, which are rotatably connected to both sides of the first handlebar 4. The first handlebar 4 is provided with spring plates 402 that are fixedly connected to the symmetrically distributed baffles 401. A first spring telescopic rod 403 is fixedly connected inside the fixed housing 3. The telescopic part of the first spring telescopic rod 403 is fixedly connected to the first handlebar 4. The first handlebar 4 is hinged to two hinge rods 404 located inside the fixed housing 3. A hinge frame 405 is hinged to the lower side of each of the two hinge rods 404. The fixed housing 3 is provided with an outlet for the two hinge frames 405 to extend out. The two hinge frames 405 are hinged to each other and rotatably connected to the fixed housing 3. By moving the first handlebar 4, the relative rotation of the two hinge frames 405 is triggered, causing the hinge frames 405 to lift the device out of the two-wheeled vehicle, achieving the power assist effect while providing convenient disassembly.
[0025] like Figures 1-6 As shown, the symmetrically distributed baffles 401 are located in the middle of the cover plate 2. The symmetrically distributed baffles 401 are all located in the middle of the symmetrically distributed sliding seats 5. The symmetrically distributed baffles 401 are used to cover the lower part of the first handle 4 to improve the concealment of the first handle 4. When the symmetrically distributed baffles 401 are parallel to the horizontal plane, from the outside of the device, the middle part of the upper side of the cover plate 2 is flat without any obvious protrusion or depression. Through this positional distribution, the thief is induced to pay attention to the second handle 6 first, rather than the hidden first handle 4.
[0026] Working principle: When installing this device inside the two-wheeled vehicle, the user presses the two baffles 401, causing them to swing along the first handle 4 while squeezing the spring plate 402. When the two baffles 401 swing to 90°, the operator pulls the first handle 4 and its parts (the telescopic part of the first spring telescopic rod 403 is compressed). The first handle 4 pulls the two articulated frames 405 through the two articulated rods 404, causing the two articulated frames 405 to rotate relative to each other. This then supports the housing 1 and its parts. Finally, the operator places the device inside the two-wheeled vehicle. After the lower sides of the two articulated frames 405 contact the two-wheeled vehicle, the operator releases the first handle 4. Under the action of gravity, the two articulated frames 405 rotate relative to each other and retract into the fixed housing 3 (the articulated rods 404 return to their original position along with the articulated frames 405). At the same time, the telescopic part of the first spring telescopic rod 403 drives the first handle 4 to move downwards and return to its original position. The two baffles 401 return to their original position parallel to the horizontal plane under the action of the spring plate 402.
[0027] When this device encounters a thief, the symmetrically distributed baffles 401 block the first handle 4, so the thief will pull the two second handles 6 first. The second handles 6 will rotate along the adjacent sliding seats 5. After the second handles 6 are in a vertical position, the second handles 6 will drive the sliding seats 5 to move upward. The sliding seats 5 will pull the extension part of the second spring telescopic rod 7. Under the action of the noise-generating coating on the extension part of the second spring telescopic rod 7, a sound will be emitted. After the noise alarm is detected, a buzzer will sound to alert the surrounding people.
[0028] When it is necessary to disassemble this device, the staff repeats the above actions. During this process, the movement of the first handle 4 triggers the relative rotation of the two hinge frames 405, which in turn supports the device, providing convenient disassembly while achieving the effect of assistance.
[0029] Example 2
[0030] Based on Example 1, such as Figure 5 and Figures 7-9 As shown, it also includes two symmetrically distributed limiting components, both of which are disposed within the housing 1. The limiting components correspond one-to-one with the sliding seats 5. The limiting components are used to restrict the position of the housing 1 within the two-wheeled vehicle. The limiting components include a pressing plate 8, which is slidably connected within the housing 1. The pressing plate 8 is slidably connected to a sliding shell 9. When the device is not stolen, the sliding shell 9 is located within the housing 1. The opposing sides of the pressing plate 8 and the sliding shell 9 are provided with inclined surfaces. Viewed from front to back, the pressing plate 8 and the adjacent sliding shell 9 are both trapezoidal. Symmetrically distributed triggering components are disposed within the housing 1, each corresponding one-to-one with the sliding seats 5. The triggering components are used to press the adjacent pressing plate 8. The side of the sliding shell 9 away from the pressing plate 8 is a rough surface. This rough surface is used to increase the friction between the sliding shell 9 and the interior of the two-wheeled vehicle. The sliding shell 9 and the pressing plate 8 are both located in the lower part of the housing 1 to enhance their concealment (since this invention will be placed in the battery compartment of the two-wheeled vehicle, it is less likely to be discovered the closer it is to the interior of the battery compartment).
[0031] like Figures 7-11 As shown, the triggering component includes two symmetrically distributed sliding frames 10. The symmetrically distributed sliding frames 10 are slidably connected to the housing 1. An elastic element 11 is fixed between the back side of the symmetrically distributed sliding frames 10 and the housing 1. An elastic plate 12 is provided between the symmetrically distributed sliding frames 10 and located inside the housing 1. The elastic plate 12 is used to press the adjacent pressing plate 8. The elastic element 11 is a spring in a stored state. The elastic plate 12 initially has elastic force, but is clamped by the two symmetrically distributed sliding frames 10.
[0032] like Figures 7-11As shown, each of the symmetrically distributed sliding frames 10 is hinged with a hinge plate 13. The symmetrically distributed hinge plates 13 are hinged to each other and are used to abut against the elastic plate 12. The elastic plate 12 is arc-shaped, and the hinge plates 13 are V-shaped. The sliding seat 5 is fixedly connected to symmetrically distributed sliding rods 14. The symmetrically distributed sliding rods 14 slide along the shell 1. The sliding rods 14 correspond one-to-one with the sliding frames 10 and are used to limit the sliding frames 10. Each of the symmetrically distributed sliding frames 10 has a pulling member 15 fixedly connected to its opposite side inside the shell 1. The pulling member 15 consists of a loosely connected pull rope and a sliding block. One side of the pull rope is fixedly connected to the sliding block, and the other side of the pull rope is fixedly connected to the sliding frame 10. The sliding frame 10 is provided with a serrated part 16. The body 1 has an elastic limiting frame 17 fixedly connected inside, which corresponds one-to-one with the serrated part 16. The elastic limiting frame 17 is used to lock the serrated part 16 in one direction. When it is necessary to manually reset the sliding frame 10, the telescopic part of the elastic limiting frame 17 is first attracted by an external magnet (the telescopic part is made of a material that can be attracted by a magnet, while the materials of the housing 1 and the sliding frame 10 are not attracted by a magnet), so that the elastic limiting frame 17 is released from contact with the adjacent serrated part 16, thereby releasing the restriction on the adjacent sliding frame 10. Then, the sliding frame 10 is moved and reset by the pulling member 15. When the symmetrically distributed sliding frames 10 move towards each other, the elastic limiting frame 17 intermittently locks the serrated part 16, so that after the symmetrically distributed sliding frames 10 move towards each other, they will not move in opposite directions without human intervention.
[0033] Working principle: When the thief is not driven away by the sound emitted by this device, the sliding seat 5 drives the two adjacent sliding rods 14 to continue moving upward. When the two sliding rods 14 are no longer in contact with the corresponding sliding frame 10, the elastic force provided by the elastic elements 11 distributed on both sides causes the two sliding frames 10 to move towards each other and press against the elastic plate 12. During this process, the two hinge plates 13 are folded in half, providing support force to the elastic plate 12. Under the action of the elastic plate 12's own elastic force and the pressure from the two sliding frames 10 (the serrated part 16 contacts the elastic limiting frame 17 during the movement of the sliding frame 10), the sliding direction of the sliding frame 10 is restricted. The effect of the two sliding frames 10 moving towards each other at this moment causes the elastic plate 12 to press the corresponding pressing plate 8. The pressing plate 8 squeezes the corresponding sliding shell 9 out of the shell 1. The sliding shell 9 then comes into contact with the two-wheeled vehicle and increases the friction between it and the two-wheeled vehicle due to the action of its own rough surface. When the sliding seat 5 is pulled by the thief, it drives the shell 1 to move upward. At this time, the pressing plate 8 and the sliding shell 9 move relative to each other. Under the guidance of the inclined surfaces of the two, the friction between the sliding shell 9 and the two-wheeled vehicle is increased, thereby achieving the mechanical self-locking effect of "the tighter it gets," increasing the difficulty of disassembly and thus preventing the device from being quickly stolen.
[0034] The technical principles of the embodiments of the present invention have been described above with reference to specific examples. These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the embodiments of the present invention.
