Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, and particularly relates to a separable shell of an electric vehicle controller. Background Art

[0002] As a crucial component in the vehicle system, the electric vehicle controller is responsible for receiving signals from sensors, calculating, and then controlling the operation of each actuator. Its stability and protection directly affect the performance and safety of the electric vehicle. The controller usually includes a main board, connecting wires, and a sturdy outer shell. Among them, the outer shell not only protects the internal electronic components from physical damage but also prevents water and dust from invading to maintain the normal operation of the device.

[0003] Most of the current electric vehicle controller shells on the market are of an integrated design, and usually, the front cover is attached to the shell by means of screw fixation. Although this design is easy to install initially, after the electric vehicle has been used for a long time, especially on roads with many bumps, due to the influence of vibration and impact, the screw interfaces may become loose, resulting in a reduction in the stability of the front cover and increasing the risk of damage to the internal components of the controller. Once the front cover becomes loose or falls off, dust and moisture may invade the inside of the shell, causing corrosion or short circuit to the electronic components. In severe cases, it may lead to the failure of the controller function, increasing the probability of accidents and posing a major hidden danger to vehicle safety.

[0004] Therefore, there is an urgent need for a separable shell of an electric vehicle controller to solve the technical defects mentioned in the above technology. Content of the Utility Model
