On-board device with limit function

Abstract

The invention provides a vehicle-mounted device with a position-limiting function, which includes a box body, a pallet assembly slidably connected in the box body, a door panel connected to one end of the box body, and a door panel abutting against the door panel close to the box body. An adjustable elastic structure on one side of the box; two ends of the box are respectively provided with a limiting structure, and the pallet assembly can slide between the limiting structures at both ends of the box; the supporting plate Two ends of the component abut against a limiting structure and the elastic structure respectively. The vehicle-mounted device with the position limiting function provided by the invention has good fixing effect, convenient movement and relatively simple structure.

Description

【Technical field】 [0001] The invention relates to the technical field of photoelectric instruments, in particular to a vehicle-mounted device with a limit function. 【Background technique】 [0002] There are many kinds of optoelectronic equipment in the vehicle-mounted equipment used for optical measurement. In order to obtain the photoelectric signal of the optoelectronic equipment, the vehicle-mounted optoelectronic equipment must have power supplies, circuit boards and other components that need to be installed in the chassis. in the component. [0003] The existing vehicle-mounted case has the following defects: when the pallet assembly is pushed and pulled in the case, the positions at both ends of the case can be limited, but there is no position-limiting structure in the middle process. The box body is installed in the fixed part of the vehicle-mounted equipment. During the driving process of the car, the pallet assembly in the box body cannot be completely fixed, whi...

Problems solved by technology

[0003] The existing vehicle-mounted chassis has the following defects: when the pallet assembly is pushed and pulled in the box, the positions at both ends of the box can be limited, but there is no limit structure in the middle process

The box body is installed in the fixed part of the vehicle-mounted equipment. During the driving process of the car, the pallet assembly in the box body cannot be completely fixed, which will cause the circuit board and other components on the pallet assembly Vibration, causing damage to components such as circuit boards

Moreover, due to the limitation of the box structure, the pallet assembly needs to be dragged out of the box when repairing and maintaining the circuit board on the pallet assembly, which is not only time-consuming and laborious, but also easily damages the circuit on the pallet assembly plate
