Technical Field

[0001] This utility model belongs to the field of electric bicycle technology, specifically a side-mounted mounting structure for an electric bicycle battery box. Background Technology

[0002] Battery boxes for electric bicycles typically need to be easy to disassemble and install for convenient charging or replacement. Current technologies offer various installation methods for battery boxes, but they generally suffer from issues such as insecure locking and inconvenient operation. For example, some battery boxes use a simple plug-and-play structure, which facilitates installation but lacks an effective locking mechanism, making them prone to loosening due to vibrations during vehicle operation, posing a safety hazard. Other battery boxes are typically secured with screws or other structures, ensuring stability after assembly, but these methods are not convenient for installation and disassembly, resulting in a poor user experience. Utility Model Content

[0003] The purpose of this utility model is to provide an installation structure for a side-mounted battery box for electric bicycles in order to solve the problems mentioned above.

[0004] The technical solution adopted by this utility model is as follows: A side-mounted mounting structure for an electric bicycle battery box includes a battery frame and a battery box. The battery frame has a mounting groove with a side opening. The battery box is detachably mounted in the mounting groove. A locking mechanism is provided on the top of the battery frame. The locking mechanism includes a linkage assembly and a handle and a locking block respectively coupled to its two ends. The top of the battery box is recessed downward to form a locking groove corresponding to the locking block. When the handle is pressed down, the linkage assembly drives the locking block to move downward and embed into the locking groove to achieve a locking operation. When the handle is pulled upward, the linkage assembly drives the locking block to move upward and disengage from the locking groove to achieve unlocking.

[0005] In a preferred embodiment, the top of the battery frame is recessed to form a receiving cavity for accommodating the locking mechanism in a locked state.

[0006] In a preferred embodiment, there is a gap between the handle and the receiving cavity for inserting a finger, and the end of the handle facing away from the gap is rotatably mounted in the battery frame via a pivot.

[0007] In a preferred embodiment, the linkage assembly includes a first linkage portion and a second linkage portion hinged together, the end of the first linkage portion away from the second linkage portion being connected to the bottom of the handle, and the end of the second linkage portion away from the first linkage portion being connected to the top of the locking block.

[0008] In a preferred embodiment, the bottom of the handle and the top of the locking block are respectively provided with lugs that connect to the first link portion and the second link portion, and there is an accommodating space between the handle and the locking block to accommodate the folded link assembly.

[0009] In a preferred embodiment, when the locking mechanism is in the locked state, the handle and the linkage assembly form a dead-point stabilizing structure.

[0010] In a preferred embodiment, a guide groove corresponding to the locking groove is provided through the bottom of the receiving cavity. The guide groove has convex surfaces at both ends, and the locking block has concave surfaces at both ends that are adapted to the convex surfaces. The locking block is disposed in the guide groove and can move up and down along the guide groove.

[0011] In a preferred embodiment, the bottom of the locking block is rounded.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by setting a locking mechanism consisting of a handle, a connecting rod assembly and a locking block, the locking block can be moved up and down by pressing or pulling the handle. During the up and down movement of the locking block, the battery box can be locked and unlocked, which effectively improves the convenience of installing and removing the battery box. 2. In this utility model, the locking mechanism can be completely stored in the housing cavity of the battery frame when locked, which not only makes the appearance neat, but also avoids the influence of the external environment on the mechanism, thus improving the service life and reliability. 3. In this utility model, by setting a dead-point stabilizing structure, the locking state is made more stable, effectively preventing the battery box from loosening due to vibration during vehicle operation, thus improving safety.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional 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.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Reference Figure 1-4 A side-mounted mounting structure for an electric bicycle battery box includes a battery frame 100 and a battery box 200 (battery body not shown). The battery frame 100 has a mounting groove 130 with a side opening. The battery box 200 is detachably mounted in the mounting groove 130. A locking mechanism 300 is provided on the top of the battery frame 100. The locking mechanism 300 includes a linkage assembly and a handle 310 and a locking block 340 respectively coupled to its two ends. The top of the battery box 200 is recessed downward to form a locking groove 210 corresponding to the locking block 340. When the handle 310 is pressed down, the linkage assembly drives the locking block 340 to move downward and embed into the locking groove 210 to achieve a locking operation. When the handle 310 is pulled upward, the linkage assembly drives the locking block 340 to move upward and disengage from the locking groove 210 to achieve an unlocking operation.

[0019] By adopting the above technical solution, the pressing / pulling action of the handle 310 is converted into the vertical movement of the locking block 340 through the lever principle. This enables the battery box 200 to be reliably locked vertically after being pushed into the mounting groove 130 from the side, through the cooperation of the locking block 340 and the locking groove 210. This effectively improves the convenience of installing and removing the battery box. Moreover, the locking action is perpendicular to the installation direction and does not interfere with each other, resulting in high reliability.

[0020] In this embodiment, please refer to Figure 1 and Figure 4 As shown, the top of the battery frame 100 is recessed to form a receiving cavity 110 for accommodating the locking mechanism 300 in the locked state. The locking mechanism 300 is accommodated in the receiving cavity 110 at the top of the battery frame 100 so that the entire mechanism does not protrude outward in the locked state, and is integrated with the body lines, resulting in a clean appearance. At the same time, this design can effectively prevent the locking mechanism 300 from being damaged or unlocked by accidental impact from external objects when the vehicle is parked or in motion.

[0021] In this embodiment, please refer to Figure 1 and Figure 4 As shown, there is a gap 120 between the handle 310 and the receiving cavity 110 for the fingers to insert. The end of the handle 310 facing away from the gap 120 is rotatably mounted in the battery frame 100 via a pivot. The gap 120 between the handle 310 and the receiving cavity 110 provides operating space for the user's fingers, making the unlocking action of pulling the handle 310 upward very effortless and convenient.

[0022] In this embodiment, please refer to Figure 2 and Figure 4 As shown, the linkage assembly includes a first linkage portion 320 and a second linkage portion 330 hinged together. The end of the first linkage portion 320 away from the second linkage portion 330 is connected to the bottom of the handle 310, and the end of the second linkage portion 330 away from the first linkage portion 320 is connected to the top of the locking block 340. The bottom of the handle 310 and the top of the locking block 340 are respectively provided with lugs 341 that connect to the first linkage portion 320 and the second linkage portion 330. There is an accommodating space between the handle 310 and the locking block 340 to accommodate the folded linkage assembly. The design of the lugs 341 provides a stable fulcrum for the linkage connection, enhances the connection strength, and the reserved accommodating space ensures that the linkage assembly will not interfere with the handle 310 or the locking block 340 when folded, ensuring smooth operation and allowing the entire locking mechanism 300 to be fully retracted in the non-working state, resulting in a more compact structure.

[0023] It is worth mentioning that when the locking mechanism 300 is in the locked state, the handle 310 and the linkage assembly form a dead-point stabilizing structure. Utilizing the "dead-point" principle, when the locking mechanism 300 is subjected to an upward reaction force in the locked state, it cannot automatically drive the linkage assembly to reverse. Unlocking requires actively pulling the handle 310 upwards. This effectively prevents the lock from loosening or accidentally unlocking due to vehicle vibration, ensuring extremely reliable locking. The motion dead-point stabilizing structure is a commonly used construction in linkage assemblies; the specific implementation of self-locking will not be elaborated upon here.

[0024] In this embodiment, please refer to Figure 2 and Figure 4As shown, the bottom of the receiving cavity 110 is provided with a guide groove 140 corresponding to the locking groove 210. The guide groove 140 has convex surfaces at both ends. The locking block 340 has concave surfaces 342 at both ends that are adapted to the convex surfaces. The locking block 340 is set in the guide groove 140 and can move up and down along the guide groove 140. The guide groove 140 ensures that the locking block 340 can only move in the preset vertical direction, preventing it from deflecting or getting stuck during the movement. The cooperation between the concave surface 342 and the convex surface further guides the movement on the one hand, and also plays a limiting role on the other hand, preventing the locking block 340 from deflecting excessively, thus ensuring the accurate alignment of the locking block 340 and the locking groove 210.

[0025] In this embodiment, please refer to Figure 2 As shown. The bottom of the locking block 340 is rounded. Rounding the bottom of the locking block 340 is equivalent to adding a guide slope. Even if there is a slight misalignment between the battery box 200 and the locking block 340, the rounded corner can guide the locking block 340 to slide into the locking groove 210, which reduces the assembly difficulty, improves the smoothness of operation, and reduces the wear of the locking block and the edge of the locking groove.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
