What is a car front bumper bracket
The car bumper bracket is an important component installed on the bumper, used to support the bumper and ensure its stable connection with the vehicle body. These supports are usually made of metal or plastic and have sufficient strength and rigidity to withstand external impacts during collisions. The design and material selection of bumper brackets are of vital importance for enhancing the safety performance of automobiles.
The bumper bracket is the link that connects the bumper and the vehicle body parts. When designing a bracket, the first thing to pay attention to is the strength issue, including the strength of the bracket itself and the strength of the connection structure with the bumper or the vehicle body. For the bracket itself, in the structural design, the strength requirements of the bracket are met by increasing the main wall thickness or selecting PP-GF30 and POM materials with higher strength. In addition, reinforcing ribs will be added to the installation surface of the bracket to prevent cracking when the bracket is tightened. For the connection structure, it is necessary to reasonably arrange the cantilever length, thickness and spacing of the connection clips with the bumper skin to ensure a stable and reliable connection.
Of course, while ensuring the strength of the support, the lightweight requirements of the support should also be met. For the side brackets of the front and rear bumpers, they should be designed as a "回" shaped box structure as much as possible. This not only meets the strength requirements of the brackets but also effectively reduces their weight, thereby saving costs. At the same time, on the path where rainwater invasts, such as on the countertop or installation surface of the support, it is also necessary to consider adding new leakage holes to prevent local water accumulation.
In addition, during the design process of the bracket, the gap requirements between it and the surrounding components also need to be taken into consideration. For instance, in the central position of the middle bracket of the front bumper, to avoid parts such as the engine hood lock and the engine hood lock bracket, the bracket needs to be partially removed for avoidance. At the same time, this area also needs to be checked for hand space. For instance, the large support on the side of the rear bumper usually overlaps with the positions of parts such as the pressure relief valve and the rear detection radar. The support needs to be cut off and avoided according to the envelope of the surrounding parts, the assembly of the wiring harness and the direction.
The function of the front bumper bracket is to absorb and mitigate the external impact force when the vehicle or driver is subjected to a collision force. The bumper is a buffering device that reduces the injury to the people inside the vehicle and protects the safety of both the person and the vehicle.
Background technology: Currently, the middle bracket in the front bumper of existing vehicles can either support the front bumper or absorb energy. Therefore, when designing a vehicle, it is not only necessary to design a middle bracket with a supporting function, but also to add additional energy-absorbing components. This will increase the number of parts and lead to an increase in vehicle cost and overall weight.
Technical implementation elements: The present utility model aims to solve at least one of the above-mentioned technical problems in the prior art to a certain extent. To this end, the present utility model proposes a front bumper middle bracket, which has both the supporting function and the energy absorption function simultaneously. The utility model also proposes a vehicle with the above-mentioned middle bracket in the front bumper.
The bracket in the front bumper according to the embodiment of the present utility model includes: an upper body mounting plate, which is suitable for being attached to the inner surface of the front bumper; Energy-absorbing structure, the energy-absorbing structure is connected below the upper body mounting plate; The lower body mounting plate is connected below the energy-absorbing structure.
Specifically, the energy-absorbing structure is an energy-absorbing bulge that is circumferentially closed and protrudes forward in the middle. When the front bumper of the vehicle deforms into the interior due to a collision, the energy-absorbing bulge can collapse and deform, thereby absorbing part of the collision energy.
According to a further embodiment of the present utility model, the front bumper includes an upper plate, which is inclined and extends upward in the direction from front to back. The upper body mounting plate is inclined in the same direction as the upper plate and is attached to the inner surface of the upper plate. Thus, the upper body mounting plate can better support the upper plate of the vehicle's front bumper and prevent the upper plate from falling.
According to the front bumper middle bracket of one embodiment of the present utility model, the upper body mounting plate is provided with multiple upper mounting holes distributed along the length direction of the middle bracket. Bolts pass through the upper mounting holes, and the upper body mounting plate can be fixed on the vehicle body.
Further, the lower body mounting plate is provided with multiple lower mounting holes distributed along the length direction of the middle bracket. Bolts pass through the lower mounting holes, allowing the lower body mounting plate to be fixed to the vehicle body.
Optionally, the number of upper installation holes is greater than that of lower installation holes.
Optionally, multiple avoidance grooves are provided on the upper body mounting plate, each located between two adjacent upper mounting holes. These avoidance grooves offer positions for the installation of other components.
Further, the middle bracket is arc-shaped and follows the curvature of the inner surface of the front bumper.
The vehicle according to another embodiment of the present utility model includes the middle bracket of the front bumper of the above-mentioned embodiment.
