Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle accessories, in particular to an electric bicycle battery installation device with an anti-theft mechanism. Background Art

[0002] An electric bicycle is a means of transportation that uses a battery as an auxiliary energy source and is equipped with a motor, controller, battery, handlebars, brake handles and other operating components and a display instrument system based on an ordinary bicycle. Compared with a conventional bicycle, it is more labor-saving and quick to ride. The battery of an electric bicycle is generally installed in the platform area in front of the saddle or in the empty area under the saddle. There is usually a battery mounting frame to facilitate the battery to be inserted and arranged neatly.

[0003] The common electric bicycle battery installation devices on the market are mostly similar in structure, mainly with a steel frame and an opening on the top. The battery is directly inserted from the opening on the top of the frame to form a regular and strict arrangement. There are some functional deficiencies in actual use and there is room for improvement. For example, whether it is an electric car or an electric bicycle, its most valuable battery is also the component with the highest chance of being stolen, and skilled thieves can often crack the vehicle's built-in locks and remove the battery within a few minutes, so it does not have the battery anti-theft function; secondly, battery short circuit and spontaneous combustion are also common damage problems of electric bicycles. Before the battery catches fire, its own temperature will rise rapidly and will only start to burn after reaching a critical value. When the battery heats up, the rider cannot feel it, so it does not have the function of battery high temperature reminder; in addition, the steel outer frame itself has a certain strength, but the side is a weak surface. When there is an external force impact, it is easy to squeeze the battery inward, causing battery damage and fire, etc., and it does not have the function of side protection.
