Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to an automobile bumper bracket. Background Art

[0002] A car bumper is generally a car safety protection device, which may include a front bumper and a rear bumper, and is usually mounted on the frame of the car to prevent damage to the car when the car is slightly collided.

[0003] The guard bumper is connected to the frame through a bracket. As an example, for the pickup truck models currently in China that use the Isuzu chassis, when installing most of the guard bumpers on the market, the most commonly used bracket is a single-piece steel plate bracket. This bracket is only fixed to the frame by bolts, and has problems such as poor reliability, simple structure, insufficient support, and easy deformation. Utility Model Content
