Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically a smart bicycle battery box. Background Technology

[0002] Intelligent bicycles, also known as electric-assisted bicycles, are a new type of labor-saving transportation tool. They rely on manual pedaling to power the chain and wheels, with batteries providing auxiliary power. Through a motor and power assistance system, they enable a combination of manual and electric-assisted riding, saving energy during activities.

[0003] The main difference between an electric-assist bicycle and a single-pedal-driven bicycle lies in the inclusion of a motor, battery, and control board. The biggest difference from an electric bicycle is that an electric-assist bicycle lacks a control valve—a mechanism for adjusting the motor's output power—and instead relies on a torque sensor and motor controller to automatically complete the acceleration process. During operation, the electric-assist bicycle collects riding parameters through sensors to determine whether the rider needs motor assistance and, if so, how much assistance is required.

[0004] Typically, the battery box is installed on the middle tube, lower tube, or upper tube, with the entire battery box exposed to the outside. Since the usage scenarios are mostly outdoors, affected by bumpy roads and weather conditions, the requirements for the battery box structure stability, assembly strength, and water-proof performance are relatively high. Existing smart bicycles are unable to meet these requirements. Utility Model Content

[0005] The purpose of this utility model is to provide a battery box for smart bicycles to solve the problems of insufficient structural stability, assembly strength and water-proof performance of existing battery boxes on smart bicycles.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a battery box for a smart bicycle, comprising:

[0007] The battery box body has an internal cavity for placing a battery pack, an opening at the top of the cavity, and first connecting ears on both sides of the opening.

[0012] Both the first and second locking blocks are elastically slidably connected to the corresponding slots of the first and second connecting ears via elastic elements.

[0013] As a further description of the above technical solution:

[0014] The first and second card blocks have wedge-shaped abutment surfaces on their outer top and bottom, with the inclination angle of the top wedge-shaped abutment surface being higher than that of the bottom wedge-shaped abutment surface. The third card block has wedge-shaped abutment surfaces on its inner top and bottom, with the inclination angle of the bottom wedge-shaped abutment surface being higher than that of the top wedge-shaped abutment surface.

[0015] As a further description of the above technical solution:

[0016] The top outer side of the second connecting ear is provided with a positioning notch that abuts and engages with the corresponding first card block, and the top outer side of the first connecting ear or the top inner side of the second connecting ear is provided with an avoidance notch that corresponds to the flip cover.

[0017] As a further description of the above technical solution:

[0018] The water-blocking membrane is positioned on opposite sides of opposite sides of the battery box body, and its other opposite sides are positioned along the length of the gripping ropes on both sides. The ends of the two gripping ropes are positioned on the other opposite sides of the battery box body.

[0019] As a further description of the above technical solution:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are 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.

[0033] Please see Figure 1-2 This utility model provides a technical solution: a battery box for a smart bicycle, comprising:

[0034] The battery box body 1 has an internal cavity for placing a battery pack. The top of the cavity has an opening, and the battery box body 1 has first connecting ears 11 on both sides of the opening.

[0035] The battery box top cover 2 is assembled on the opening, and second connecting ears 21 are provided on both sides of its top surface. The first connecting ear 11 and the second connecting ear 21 are assembled on the side and positioned by the first locking block 12.

[0036] The flip cover 3 is rotatably mounted on the battery box body 1 or the battery box top cover 2 via a hinge 31. A third locking block 32 is provided on the inner cavity sidewall of the flip cover 32, which is engaged and positioned with the second locking block 13 on the outer side of the first connecting ear 11 and the second connecting ear 21.

[0037] A water-repellent membrane 4 is applied to the surface of the battery box body 1 and the battery box top cover 2.

[0038] The first locking block 12 and the second locking block 13 are both elastically slidably connected to the grooves of the corresponding first connecting ear 11 and second connecting ear 21 via elastic elements. The above design ensures that when the corresponding structures are engaged, if one side of the first locking block 12 or the second locking block 13 is pressed, it will first retract into the groove. After the pressure is released, it will elastically reset and engage and position itself through the other side, reducing wear on the engagement structure.

[0039] The first locking block 12 and the second locking block 13 are provided with wedge-shaped abutment surfaces on their outer top and bottom, and the inclination angle of the wedge-shaped abutment surface at the top is higher than that at the bottom. The third locking block 32 is provided with wedge-shaped abutment surfaces on its inner top and bottom, and the inclination angle of the wedge-shaped abutment surface at the bottom is higher than that at the top. This makes the elastic resistance smaller when the two connecting ears are pressed in, and larger when they are pulled out, making the installation easier and the positioning more stable.

[0040] The top outer side of the second connecting ear 21 is provided with a positioning notch 22 that abuts and engages with the corresponding first locking block 12, and the top outer side of the first connecting ear 11 or the top inner side of the second connecting ear 21 is provided with an avoidance notch 23 that corresponds to the flip cover 3.

[0041] The water-retaining membrane 4 is positioned on opposite sides of the battery box body 1, and its other opposite sides are positioned along its length on the gripping ropes 5 on both sides. The ends of the two gripping ropes 5 are positioned on the other opposite side of the battery box body 1. The above structure, through the opening and closing design of the water-retaining membrane 4, allows for repeated disassembly and assembly of the battery box top cover 2, and the retraction and opening of the water-retaining membrane 4 during battery pack maintenance and replacement, enabling its cyclical use.

[0042] The battery box body 1 has an arc-shaped groove 14 on its side wall for engaging and positioning the gripper rope 5, thereby positioning the gripper rope 5 and positioning the water-blocking membrane 4 when it is unfolded, making the water-blocking and waterproofing performance at the battery box interface more efficient.

[0043] The battery box top cover 2 is provided with a U-shaped handle 24, which makes it easy to grab and disassemble the battery box top cover 2.

[0044] The working principle of a smart bicycle battery box in this embodiment includes: after the battery pack is placed inside the battery box, during assembly, the U-shaped handle 24 is held, and the top cover 2 of the battery box is pressed into the opening. The two connecting ears are joined together, and the second connecting ear 21 presses the first locking block 12 into the groove. When the battery box body 1 and the top cover 2 of the battery box are installed in place, the first locking block 12 is released from pressure, elastically resets, and cooperates with the positioning notch 22 for structural positioning. The flip cover 3 is flipped so that the second locking block 13 engages with the third locking block 32 in a similar principle and movement process, thus completing the battery box assembly. Afterwards, the two gripping ropes 5 are grasped, rotated, and embedded into the arc-shaped groove 14, so that the water-blocking membrane 4 unfolds and covers the top of the battery box to achieve the water-blocking function. When disassembling the battery box, the above steps are performed in reverse order.

[0045] In summary, due to the adoption of the above technical solution, the intelligent bicycle battery box of this embodiment has the following advantages compared with the prior art:

[0046] The battery box of this utility model achieves initial positioning through two connecting ears and a first locking block, and then a flip cover is placed on the two connecting ears, which, together with the second and third locking blocks, achieves secondary positioning of the battery box, ensuring assembly stability. The water-blocking membrane connected to the grip rope enables the switching between a water-blocking and open state of the top of the battery box, and the arc-shaped groove ensures that the water-blocking membrane is fully deployed and covers the top of the battery box and the joint of the battery box structure, improving the water-blocking and waterproof performance of the battery box on the smart bicycle.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
