Description

Technical Field

[0001] The utility model relates to the technical field of secondary batteries, and specifically refers to a battery replacement module structure of a two-wheeled electric vehicle with a locking effect. Background Art

[0002] The battery swap module of a two-wheeled electric vehicle usually refers to the battery assembly of the electric vehicle, which is used to replace the original battery or charge it. The battery assembly of an electric vehicle will gradually wear out during use, so it needs to be replaced or charged. The battery swap module usually includes components such as a battery management system, a connector, and a battery module to achieve a fast and convenient battery replacement or charging process.

[0003] At present, the battery swap module of two-wheeled electric vehicles basically adopts a box structure. In order to avoid abnormalities of the battery swap module caused by vibration, the box cover is generally directly sealed with ultrasound or adhesives after the battery swap module is assembled, which brings difficulties to subsequent maintenance. At the same time, the battery swap module also includes components such as a battery management system and a connector. After the battery module is enclosed in the box, there is still a certain amount of shaking space. After the battery module is placed in the box, it is still inevitable that it will vibrate inside the box during use or transportation, which brings reliability risks. In addition, in actual applications, the design and use of the battery swap module will vary depending on the type of electric vehicle. Some electric vehicles use detachable battery modules, and users need to replace the battery modules. How to improve the convenience of disassembly while ensuring reliability has also become a shortcoming that plagues the development of two-wheeled electric battery swap modules. Utility Model Content

[0004] The purpose of the utility model is to provide a two-wheel electric vehicle battery replacement module structure with a locking effect, which has the characteristics of good locking effect, convenient disassembly and strong versatility.

[0005] The utility model can be realized by the following technical solutions:

[0006] The utility model discloses a two-wheel electric vehicle battery replacement module structure with a locking effect, comprising a box body and a box cover for accommodating a battery module, a locking frame is also sleeved on the box body mouth, the locking frame is movably fastened to the box body by the box cover, and a locking strip is provided on the locking frame which is elastically pressed onto the surface of the battery module.

[0007] Furthermore, the locking strip is pressed on the top of the battery module by a countersunk screw that is movably embedded in the outer wall of the locking frame or an integrated through-type press. The countersunk screw method is convenient for disassembly and maintenance; the integrated molding method simplifies the assembly process and can be selected according to actual conditions.

[0008] Furthermore, the number of locking strips is several, and the several locking strips are arranged in parallel or staggered. By adopting the parallel or staggered arrangement, the locking strips can press the surface of the battery module at different positions to form a better locking and fixing effect.

[0009] Furthermore, the locking strip is a rubber elastic locking strip, a silicone elastic locking strip, or a polyurethane elastic locking strip, and the above strip types are all common elastic plastic strip types, which are easy to obtain and process, and save manufacturing costs.

[0010] Furthermore, the width of the outer wall of the locking frame is consistent with or smaller than the width of the inner wall of the box, and is tightly embedded in the inner cavity of the box and pressed against the surface of the battery module to ensure the locking and fixing effect.

[0011] Furthermore, the box body and the box cover are movably buckled, and the outer wall of the box body is provided with a screw positioning hole corresponding to the position of the countersunk screw of the locking frame. Through the screw positioning hole, the countersunk screw can pass through the box cover into the locking frame, realizing the integration of the assembly and sealing process and the pressing and fixing process of the battery module, thereby ensuring reliability.

[0012] Furthermore, a display screen installation area and a terminal lead-out hole are provided on the box cover. The display screen installation area is provided to facilitate installation of a display screen for visual observation of the battery module status; and the terminal lead-out hole is provided to facilitate installation of wire lead-out terminals.

[0013] Furthermore, the battery module is a lead-acid battery module, a lithium-ion battery module or a sodium-ion battery module to meet the usage requirements of different battery types.

[0014] Furthermore, the lithium-ion battery module is a ternary battery module, a lithium manganese oxide battery module, a lithium cobalt oxide battery module or a lithium iron phosphate battery module.

[0015] Furthermore, the sodium ion battery module is a polyanion battery module, a layered oxide battery module or a Prussian blue battery module.

[0016] The utility model discloses a two-wheel electric vehicle battery replacement module structure with a locking effect, which has the following beneficial effects:

[0017] First, the locking effect is good. By adopting the locking frame and locking strip, the battery module can be effectively fixed inside the box in a spring-pressed manner, and the risk of shaking or vibration is significantly reduced, thereby improving the reliability of the battery swap module.

[0018] Second, it is easy to disassemble. By adopting a locking frame, the box cover can be buckled and movably set on the top of the box body, and the processing and assembly requirements of the battery replacement module can be met without a fixed closure;

[0019] Third, it has strong versatility. The battery swap module structure of the utility model only needs to set a locking frame and a locking strip between the original box body and the box cover, without the need to perform structural modification on the inside of the box body or the box cover, thus meeting the applicability requirements of the existing battery swap module box structure.
