Description

Technical Field

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

[0002] A power-assisted bicycle is a new type of two-wheeled vehicle, belonging to the category of bicycles. It uses batteries as an auxiliary power source, is equipped with a mid-mounted motor, and has a power assistance system, making it a new type of transportation that integrates human riding and motor assistance.

[0003] In the field of electric bicycles, there are two main types of motor mounting positions. One is a mid-mounted motor, where the motor is installed in the middle of the frame, specifically at the bottom bracket. This mid-mounted motor is connected to the frame and transmits power through the chain to the rear wheel. Pedals are installed on both sides of the motor, allowing the rider to pedal even without power, with resistance no different from a normal bicycle. The other type is a hub motor, which is installed in the wheel hub. Compared to hub motors, mid-mounted motors have significant advantages in terms of technology and performance.

[0004] Currently, existing mid-mounted electric bicycles require batteries to be installed on the frame to power the internal electrical components. Installing the batteries on the outside of the frame not only affects the overall aesthetics but also makes them prone to loss. Therefore, a retractable battery compartment structure for electric bicycles is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a concealable battery compartment structure for electric-assist bicycles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a retractable battery compartment structure for an electric-assist bicycle, comprising a frame body, an installation groove at one end of the frame body, a fixing block installed above the installation groove via a groove, a slot at one end of the fixing block, a cover plate rotatably installed inside the installation groove, a locking block installed at the upper end of the cover plate, a lock body installed at one end of the fixing block and inside the frame body, a limiting hole provided at the end of the locking block near the lock body, and fixing plates installed inside the frame body above and below the installation groove.

[0007] Preferably, a battery compartment is formed inside the frame body between the two fixing plates, and a power connection plate is installed on the upper fixing plate. When the battery is placed inside the battery compartment, the electrodes on the battery contact the power connection plate, which can provide power to the internal circuit of the electric bicycle.

[0008] Preferably, two L-shaped limiting plates are symmetrically installed on the inner wall of the vehicle frame body between the two fixing plates. The L-shaped limiting plates facilitate the left and right positioning of the battery inside the battery compartment, preventing the battery from shaking inside the battery compartment. In addition, the L-shaped limiting plates allow three surfaces of the battery to contact the air, preventing heat from accumulating on the battery surface.

[0009] Preferably, the bottom of the mounting groove is provided with two notches, and a rotating block is rotatably installed inside each of the two notches via a rotating shaft. The upper end of each rotating block is provided with a slot, and the lower ends of the cover plate are provided with inserts. The rotating blocks facilitate the rotation of the cover plate. When the cover plate is locked by the lock body, the rotating blocks are restricted and will not rotate. One end of the cover plate will not come out of the rotating block, effectively ensuring the stability of the cover plate after it is fixed by the lock body. Furthermore, the cover plate can be removed separately to avoid obstructing the installation of the battery.

[0010] Preferably, the surface of the frame body on both sides of the mounting groove is provided with sealing grooves, and the shape of the cover plate matches the mounting groove and the sealing groove. The setting of the sealing groove effectively prevents external rainwater from entering the interior of the frame body through the gap between the cover plate and the frame body, and effectively ensures the sealing of the cover plate installation location.

[0011] Preferably, the lock body is provided with a lock block, the size and shape of which match the limiting hole. The lock body is a known prior art battery box lock, which is also a known prior art. The lock body can be rotated by a key, causing the lock block to extend into the limiting hole, thereby realizing the installation and fixation of the cover plate. Each lock body is equipped with a corresponding key. When the key is in use, the lock body cannot be opened, thus providing a certain anti-theft function.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The concealed battery compartment structure of the electric-assist bicycle allows the battery to be installed inside the bicycle frame and covered by a rotating cover. The cover is secured with a locking mechanism, effectively ensuring the overall aesthetics of the electric-assist bicycle and preventing battery loss.

[0014] 2. The concealed battery compartment structure of the electric-assist bicycle uses two L-shaped limiting plates to limit the left and right movement of the battery inside the compartment, preventing the battery from shaking inside. The L-shaped limiting plates also allow three surfaces of the battery to contact the air inside the electric-assist bicycle frame, preventing the heat generated during battery use from condensing on the battery surface.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figures 1 to 5As shown, this embodiment of the concealed electric-assist bicycle battery compartment structure includes a frame body 1, which is part of the electric-assist bicycle frame and is used to house the battery. The frame body 1 is provided with a charging port for charging the battery. One end of the frame body 1 is provided with a mounting groove 2 for installing a cover plate 5. A fixing block 3 is installed above the mounting groove 2 through a groove. One end of the fixing block 3 is provided with a slot 4. The cover plate 5 is rotatably installed inside the mounting groove 2. A locking block 6 is installed on the upper end of the cover plate 5. When the cover plate 5 is installed inside the mounting groove 2, the locking block 6 on the top of the cover plate 5 is located inside the slot 4. A lock body 7 is installed at one end of the fixing block 3 and inside the frame body 1. A limiting hole 8 is provided at the end of the locking block 6 near the lock body 7. The lock body 7 is used to lock the locking block 6 to achieve the installation and fixation of the cover plate 5. Fixing plates 9 are installed inside the frame body 1 above and below the mounting groove 2. The fixing plates 9 are used to limit the upper and lower ends of the battery to prevent the battery from moving up and down in the frame body 1.

[0024] Specifically, a battery compartment is formed inside the frame body 1 between the two fixing plates 9. A power connection plate 10 is installed on the upper fixing plate 9. When the battery is put into the battery compartment, the electrodes on the battery contact the power connection plate 10, which can provide power to the internal circuit of the electric bicycle.

[0025] Furthermore, two L-shaped limiting plates 11 are symmetrically installed on the inner wall of the frame body 1 between the two fixing plates 9. The setting of the L-shaped limiting plates 11 facilitates the left and right limiting of the battery inside the battery compartment, preventing the battery from shaking inside the battery compartment. In addition, the L-shaped limiting plates 11 can make three surfaces of the battery in contact with the air, preventing the heat on the battery surface from accumulating on the battery surface and not being able to dissipate, thus increasing the heat dissipation effect of the battery to a certain extent.

[0026] Furthermore, the bottom of the mounting groove 2 is provided with two notches 12, and a rotating block 13 is rotatably installed inside each notch 12 via a rotating shaft. The upper end of each rotating block 13 is provided with a slot 14, and the lower ends of the cover plate 5 are provided with inserts 15. The rotating block 13 is designed to facilitate the rotation of the cover plate 5. When the cover plate 5 is locked by the lock body 7, the rotating block 13 is restricted and will not rotate. One end of the cover plate 5 will not come out of the rotating block 13, effectively ensuring the stability of the cover plate 5 after it is fixed by the lock body 7. The cover plate 5 can also be removed separately to avoid obstructing the installation of the battery.

[0027] Furthermore, sealing grooves 16 are provided on the surface of the frame body 1 on both sides of the mounting groove 2. The shape of the cover plate 5 matches the mounting groove 2 and the sealing groove 16. The setting of the sealing groove 16 effectively prevents external rainwater from entering the interior of the frame body 1 through the gap between the cover plate 5 and the frame body 1, effectively ensuring the sealing of the mounting location of the cover plate 5.

[0028] Furthermore, the lock body 7 is equipped with a lock block 17, which matches the size and shape of the limiting hole 8. The lock body 7 is a known prior art, and it is a battery box lock. The lock body 7 can be rotated by a key, so that the lock block 17 extends into the limiting hole 8, thereby fixing the cover plate 5. Each lock body 7 is equipped with a corresponding key. When the key is in use, the lock body 7 cannot be opened, thus providing a certain anti-theft function.

[0029] The usage method of this embodiment is as follows: When installing the battery, the battery is placed into the frame body 1 between the fixing plates 9 through the mounting slot 2. The electrodes on the battery contact the power connection plate 10 on the fixing plate 9 to supply power to the internal circuit of the electric bicycle. Then, the insert 15 at the lower end of the cover plate 5 is inserted into the slot 14 inside the rotating block 13. Then, the cover plate 5 is rotated so that the locking block 6 at the upper end of the cover plate 5 is located in the locking groove 4 inside the fixing block 3. Then, the key is used to extend the locking block 17 in the lock body 7 into the limiting position inside the locking block 6. Inside the positioning hole 8, the cover plate 5 is fixed. When the battery is inside the frame body 1, the two fixing plates 9 limit the battery vertically, and the two L-shaped limiting plates 11 limit the battery horizontally, effectively preventing the battery from shaking inside the frame body 1. The setting of the L-shaped limiting plates 11 ensures that the three surfaces of the battery do not directly contact the frame body 1, effectively preventing the heat generated by the battery during use from condensing on the battery surface. By using the key to remove the locking block 17 from the limiting hole 8 and removing the cover plate 5, the battery can be removed from inside the frame.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
