Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to a quick-change battery structure for a pushcart. Background Technology

[0002] Currently, the most common way to connect batteries and loads in electric vehicles is with the national standard three-core connector. Many manufacturers also use their own self-developed plug-in connectors. The main structural method is to use a fixed socket on the battery side and a wire harness with a plug on the load side for manual connection. For battery fixing, bolts are often used.

[0003] Electric vehicles use a wiring harness end-to-socket connection method, which is cumbersome to operate and cannot be locked after plugging. After long-term vibration, it is easy to loosen and spark, damaging the battery terminals. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution:

[0022] A quick-change battery structure for a trolley includes a quick-change bracket 1, a battery box housing 2 movably mounted inside the quick-change bracket 1, guide mechanisms at the upper and lower ends of the quick-change bracket 1 and the battery box housing 2, the guide mechanisms including slides 4, slides 4 fixedly mounted on both the upper and lower sides inside the quick-change bracket 1, bearing rollers 5 at the four corners of the bottom end of the slides 4, guide rails 6 at the middle of the upper and lower ends of the battery box housing 2, the guide rails 6 being movably connected to the bearing rollers 5, and a handle 9 fixedly mounted on the middle of the left side of the battery box housing 2, the handle 9 being made of insulated material. A fixing bracket 10 is provided on the left side of the quick-change bracket 1. A locking groove 11 is provided through the middle of the left side of the fixing bracket 10. A latch 12 matching the locking groove 11 is provided on the middle of the left side of the battery box housing 2. A battery body 3 is provided inside the battery box housing 2. A connecting mechanism is provided between the battery box housing 2 and the bottom right side of the quick-change bracket 1. The connecting mechanism includes a female connector 7. The female connector 7 is provided on the lower right side of the battery box housing 2. A male connector 8 matching the female connector 7 is fixedly installed on the lower right side of the quick-change bracket 1.

[0023] In this embodiment, the guide mechanism, the connecting mechanism, and the latch 12 work together to achieve quick battery replacement and secure connection, solving the problems of cumbersome operation and unstable connection in traditional battery connection methods. This device not only improves the efficiency of battery replacement, but also enhances the safety of battery connection, and is suitable for electric vehicles or other equipment that require frequent battery replacement.

[0024] Working Principle: The quick-change bracket 1 achieves rapid battery replacement and secure connection through the coordinated action of the guiding mechanism, connecting mechanism, and locking buckle 12. Specifically, a battery box housing 2 is movably mounted inside the quick-change bracket 1. Guide rails 6 are located at the middle of the upper and lower ends of the battery box housing 2, while slide blocks 4 are fixedly installed on both sides of the upper and lower ends of the quick-change bracket 1. The bearing rollers 5 at the bottom of the slide blocks 4 are movably connected to the guide rails 6, allowing the battery box housing 2 to slide smoothly within the quick-change bracket 1, ensuring stability and precise alignment during battery installation. When the battery box housing 2 slides into position, the female connector 7 on its lower right side automatically aligns with the male connector 8 on the lower right side of the quick-change bracket 1, completing the electrical connection between the battery and the load, avoiding the manual operation required by traditional wiring harness connections. Simultaneously, the locking buckle 12 on the middle left side of the battery box housing 2 locks with the locking groove 11 on the outer fixing bracket 10 on the left side of the quick-change bracket 1, ensuring that the battery box housing 2 will not accidentally detach during operation. In addition, the insulated handle 9 fixedly installed on the middle left side of the battery box shell 2 facilitates push-pull operation, further improving the convenience and safety of operation. Through this design, the structure not only simplifies the battery replacement process but also improves the reliability and safety of the connection, effectively solving the problems of cumbersome operation and unstable connection in traditional battery connection methods.
