Vehicle-mounted lamp with structure for preventing chassis deformation

Abstract

The invention relates to a vehicle-mounted lamp with structure for preventing chassis deformation, comprising a chassis, a mast fixing seat, an up-down pushing mechanism and a lift cylinder, wherein the mast fixing seat and the up-down pushing mechanism are fixed on the chassis; the mast fixing seat comprises a substrate, a first support arm and a second support arm convexly arranged on the substrate correspondingly; the substrate and the two support arms form a concave accommodating groove; one end of the lift cylinder is connected with the vehicle-mounted lamp and a holder and the other endis a connection part with a connection hole; the connection part is in rotation connection with the accommodating groove of the mast fixing seat; at least one support lug at the same plane as the substrate is arranged in the surrounding of the substrate of the mast fixing seat; the side on the chassis near the mast fixing seat is provided convexly with a reinforcing edge; under the coaction of the reinforcing edge and the support lug of the mast fixing seat, the chassis is not easy to deform, and the lift cylinder after many times of use will not incline and deflect as a result of chassis deformation, thereby greatly enhancing reliability of the vehicle-mounted lamp.

Description

technical field [0001] The invention relates to an anti-deformation structure, in particular to an anti-deformation structure applied to the chassis of a vehicle lamp. Background technique [0002] Vehicle-mounted liftable lamps can be installed on cars or fixed objects, can be automatically lifted and reset, are easy to operate and use, and have omni-directional positioning functions. They have been widely used in satellite news interview vehicles, broadcast vehicles, military vehicles, and public security command vehicles. , emergency communication vehicles and other special vehicles and other types of vehicles. [0003] Such as figure 1 and figure 2 As shown, they are the rear view and top view of the vehicle-mounted lamps without reinforcing edges in the chassis of the prior art after long-term use. The chassis 10 of the prior art vehicle-mounted lamps are all made of steel plates without reinforcing edges or all surrounding reinforcements are provided. Edge structur...

AI Technical Summary

Problems solved by technology

[0004] The chassis 10 without reinforced edges will be seriously deformed, causing the cylinder 40 to deflect, which will cause the gap between the gears 60 to expand and form a vicious circle, and finally cause the lamp head and the head (not shown in the figure) to fall below the designated position and get stuck, while the gears Too much force on the tip of the 60 leads to chipped teeth, and the entire set of vehicle lamps fails

[0005] The deformation phenomenon of the chassis 10 with reinforcing edges (not shown) all around it is improved to a certain extent compared with the chassis without reinforcing edges. It is inconvenient to assemble and disassemble the fixing bolts (211, 214) on 10

And because the chassis 10 is the basis of the whole set of vehicle lamps 30, almost all parts are assembled on the chassis 10, so it is difficult to maintain and replace, and damages often have to be returned to the factory for repair, reducing the reliability and scalability of the vehicle lamps
