A telescopic structure for a car chassis camera

By designing a telescopic structure for the car chassis camera, the lens module extends and retracts within the housing. Combined with guide pillars and protective measures, this solves the problems of camera susceptibility to damage and easy aging of the sealing structure, achieving efficient protection and long service life in complex environments.

AI Technical Summary

Technical Problem

Existing automotive chassis cameras are susceptible to external environmental factors such as mud, dust, and flying stones, which can lead to lens contamination or damage. Furthermore, their sealing structures are prone to aging and leakage, resulting in a short service life and making it difficult to meet the requirements for use in complex environments.

Method used

Design a telescopic structure for a car chassis camera. The lens module can extend and retract linearly within the housing. The smooth movement of the lens is achieved through the cooperation of the telescopic drive component and the guide protrusion. It is also equipped with protective measures such as bellows and sealing rings to avoid the influence of external factors.

Benefits of technology

It effectively prevents the camera from being impacted by mud, rain, flying stones, etc. during operation, extending its service life, improving system reliability and protection performance, and reducing maintenance costs.

Abstract

This utility model discloses a telescopic structure for a car chassis camera, including a housing and a lens module disposed within the housing. The housing is characterized by having a telescopic drive component for extending or retracting the lens module. The telescopic drive component has a spirally arranged groove on its outer periphery. The lens module has several guide protrusions on its outer periphery, which are inserted into the groove. The housing also has guide grooves for the guide protrusions. The telescopic drive component rotates to allow the lens module to move linearly along the guide grooves. This allows the lens module to extend and retract linearly within the housing, providing a buffering effect, preventing damage to the camera during driving, and improving the overall structural lifespan.
