The bumper bracket of the car.
Side support
The bumper bracket is the link between the bumper and the body parts. When designing the bracket, it is first necessary to pay attention to the strength problem, including the strength of the bracket itself and the strength of the structure connected with the bumper or the body. For the support itself, the structural design can meet the strength requirements of the support by increasing the main wall thickness or selecting PP-GF30 and POM materials with higher strength. In addition, reinforcing bars are added to the mounting surface of the bracket to prevent cracking when the bracket is tightened. For the connection structure, it is necessary to rationally arrange the cantilever length, thickness and spacing of the bumper skin connection buckle to make the connection stable and reliable.
Of course, while ensuring the strength of the bracket, it is also necessary to meet the lightweight requirements of the bracket. For the side brackets of the front and rear bumpers, try to design a "back" shaped box structure, which can effectively reduce the weight of the bracket while meeting the strength requirements of the bracket, thus saving costs. At the same time, on the path of rain invasion, such as on the sink or installation table of the support, it is also necessary to consider adding a new water leakage hole to prevent local water accumulation.
In addition, in the design process of the bracket, it is also necessary to consider the clearance requirements between it and the peripheral parts. For example, in the central position of the middle bracket of the front bumper, in order to avoid the engine cover lock and engine cover lock bracket and other parts, the bracket needs to be partially cut out, and the area should also be checked through the hand space. For example, the large bracket on the side of the rear bumper usually overlaps with the position of the pressure relief valve and the rear detection radar, and the bracket needs to be cut and avoided according to the envelope of the peripheral parts, the wiring harness assembly and the direction.
What is the front bumper frame?
The front bumper skeleton is a component that fixed the support of the bumper shell, and it is also a kind of anti-collision beam, which is used to absorb the collision energy when the vehicle crashes, and protect the safety of the vehicle and the occupants in the car.
The front bumper is composed of a main beam, an energy absorption box and a mounting plate connected to the car, in which the main beam and an energy absorption box can effectively absorb the collision energy of the vehicle during low-speed collision and reduce the damage of the impact force to the body longitudinal beam.
The bumper skeleton is an indispensable safety device for automobiles, which is divided into front bars, middle bars and rear bars. The front bumper frame includes the front bumper liner, the front bumper frame right bracket, the front bumper bracket left bracket, and the front bumper frame, all of which are used to support the front bumper assembly.
The anti-collision beam is an important part of the car, which is generally hidden inside the bumper and inside the door. Under the action of large impact force, when the elastic material can no longer buffer the energy, the anti-collision beam plays a role in protecting the occupants of the car. Anti-collision beams are usually made of metals, such as aluminum alloy and steel pipe, while high-end cars are generally made of aluminum alloy, and some cars are made of hard materials.
The following steps are used to install the front bar support:
Preparation: Make sure the vehicle is parked on a flat surface, Use jacks and brackets to lift the front of the vehicle for safety. Get the necessary tools, such as wrenches, screwdrivers, and check that the new bumper bracket is in good condition.
Remove the old bracket: First, needs to remove the old front bumper. This usually involves loosening the screws and clasps holding the bumper in place, carefully removing the bumper from the body, all the while taking care not to damage the body paint or other parts.
Install the new bracket: Place the new front bumper bracket in the intended position, make sure it is perfectly aligned with the interfaces on the body. Secure the support to the body using screws and clasp, ensure that each fixing point is secured in place, to ensure the support is stable.
Install the bumper: reinstall the front bumper on the new bracket, aligned with the interface between the bumper and bracket, step by step fix the bumper. ensure that all connections are properly installed, and check that the bumper is secure and is not loose.
Check and adjust: after the installation is complete, for a comprehensive check. Start the vehicle and watch the bumper for abnormal vibration or noise. At the same time, check that the clearance between the bumper and the body is even, make fine adjustments if necessary, to ensure the best appearance and performance.
By following the above steps, can successfully complete the installation of the front bumper bracket of the Enclera.
