Description

Technical Field

[0001] The utility model relates to the technical field of proximity switch installation, in particular to an installation structure of a proximity switch used for drum positioning parking. Background Art

[0002] A proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. It controls the opening and closing of the circuit by sensing the proximity of an object and is widely used in automatic control systems. Drum positioning parking usually involves a large circular drum that can simulate the vehicle's driving on actual roads. In automobile manufacturing and testing, the drum is used to test various vehicle performance, such as power, economy, comfort and handling stability. By controlling the speed and moment of inertia of the drum, different road conditions and vehicle loads can be simulated to evaluate the vehicle's performance. Therefore, the use of proximity switches in drum positioning parking can not only improve the accuracy and reliability of the operation, but also enhance the overall performance and safety of the system.

[0003] Currently, there are many forms of installation methods for proximity switches used for rotary drum positioning parking, generally including flush installation and non-flush installation. The flush installation is achieved by embedding the proximity switch in a metal mounting bracket so that the head of the proximity switch is flush with the surface of the bracket, which is suitable for scenarios where the proximity switch needs to be hidden to maintain the flatness of the device surface. The non-flush installation makes the head of the proximity switch protrude from the metal mounting bracket, which is suitable for scenarios with specific requirements for the proximity switch position or where the proximity switch does not need to be completely embedded in the mounting bracket. In view of the installation method of this structure, another more applicable installation structure is proposed, and for this purpose, an installation structure of a proximity switch for rotary drum positioning parking is proposed.
