Supporting hook cover plate opening structure

Abstract

The invention discloses a supporting hook cover plate opening structure which comprises a safety rod, a supporting hook cover plate installed on the safety rod and a rotary buckle assembly used for clamping and fixing the supporting hook cover plate to the safety rod. A gap is arranged in the supporting hook cover plate, and the rotary buckle assembly comprises a rotating part capable of rotating in the axial direction of the rotating buckle assembly and a spring used for providing restoring force for the rotating part. The opening mode of the supporting hook cover plate in the prior art is changed, a rotary opening structure is changed into a real pressing type opening structure, the problem that the supporting hook cover plate interferes with peripheral local parts when being opened is solved, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an opening structure of a hook cover plate. Background technique [0002] Due to the needs of the overall aesthetic effect of the car, in order to hide the hook hole of the towing hook, ensure the normal use of the towing hook and avoid interference between the towing device and the bumper, a hook cover needs to be installed on the bumper. The function of the support hook cover is to open the support hook cover and screw on the support hook to tow the vehicle when the vehicle needs to be towed. In the prior art, there are two ways to open the hook cover. One is the pry-up type with auxiliary tools. Since the pry-up hook cover needs auxiliary tools (such as a flat-head screwdriver, etc.) to open, it is inconvenient and has been gradually eliminated; the second type is to use the rotating shaft to open the type. . The swing-open hook cover is currently the mainstream solution...

Problems solved by technology

One is the pry-up type with auxiliary tools. Since the pry-up hook cover needs auxiliary tools (such as a flat-head screwdriver, etc.) to open, it is inconvenient and has been gradually eliminated; the second type is to use the rotating shaft to open the type.

The rotary-opening hook cover is currently the mainstream solution, but due to the limitation of the shape of the bumper, when some models are opened, the rotary-opening hook cover will partially interfere with the surrounding components, resulting in difficulty in opening

In addition, when designing the rotary-opening hook cover, the opening force is not easy to simulate and control through the early design stage. It is necessary to modify the mold to adjust the opening force after the part is formed, resulting in additional costs

With the aging of the material and repeated openings, the opening force will also decrease significantly
