[0001] This application belongs to the field of truck parts technology, specifically relating to a reversible front bumper for large trucks. Background Technology

[0002] In the existing technology, the front bumper of a large truck occupies a pivotal position in the vehicle safety protection system. It plays a key role in absorbing and mitigating external impact forces, building a solid safety barrier for the front of the vehicle. It is usually carefully crafted from high-quality materials such as metal or high-strength plastic. With the excellent strength and toughness of the materials themselves, it can efficiently absorb and reasonably disperse various impact forces from the front, thereby significantly reducing the probability of damage to the vehicle itself and the user.

[0003] However, some significant drawbacks still exist in the front bumper designs of large trucks currently on the market. Existing front bumpers are often positioned higher than the truck's cab height. In practical applications, when users open the hood for vehicle maintenance, interference easily occurs between the hood and the bumper. This makes it difficult for maintenance personnel to open the hood smoothly and fully, significantly impacting routine truck maintenance procedures, greatly increasing the difficulty and time cost of vehicle maintenance, causing considerable inconvenience to users, severely damaging the user experience, and negatively affecting the normal use and maintenance efficiency of the vehicle.

[0004] In view of this, in order to comprehensively improve the performance of the front bumper of large trucks in terms of daily maintenance convenience and multi-directional impact protection, it is now urgent to make targeted improvements to optimize the structural design of the front bumper of large trucks, completely solve the persistent problem of interference between the engine hood and the front bumper, and significantly enhance its protective effectiveness in different impact scenarios, thereby comprehensively improving the user's convenience and the overall safety performance of the vehicle, and meeting the multi-dimensional performance requirements of modern large trucks in actual operation. Utility Model Content

[0005] This application addresses the technical problem in the prior art where traditional truck front bumpers are typically one-piece designs, and the height of the bumper is usually higher than the truck's cab. When the truck's engine hood needs to be opened for maintenance, the hood will interfere with the front bumper, preventing the hood from being fully opened. During routine maintenance, the entire truck front bumper needs to be disassembled, significantly increasing truck maintenance costs. This application proposes a flip-up truck front bumper.

[0006] This application adopts the following solution: a flip-up front bumper for large trucks, including a connecting bracket with one end on the truck body, a bumper body rotatably mounted on the other end of the connecting bracket, and a fastening mechanism between the connecting bracket and the bumper body. The fastening mechanism includes a fastening claw assembly at one end of the connecting bracket, a fastening groove on the fastening claw assembly, and a fastening post on the bumper body located at a position corresponding to the fastening claw assembly.

[0024] Combination Figures 1-8The following description further illustrates the technical solution proposed in this application. This application provides a flip-up front bumper for large trucks, including a connecting bracket 1 with one end mounted on the truck body, a bumper body 2 rotatably mounted on the other end of the connecting bracket 1, and a fastening mechanism 3 between the connecting bracket 1 and the bumper body 2. The fastening mechanism 3 includes a fastening claw assembly 4 at one end of the connecting bracket 1, a fastening groove 5 on the fastening claw assembly 4, and a fastening post 6 on the bumper body 2 located at a position corresponding to the fastening claw assembly 4. When the bumper body 2 rotates towards the connecting bracket 1, the fastening post 6 extends into the fastening groove 5, so that the bumper body 2 is snapped onto the connecting bracket 1.

[0025] This application provides a flip-up front bumper for large trucks, comprising a connecting bracket, a bumper body rotatably mounted on the other end of the connecting bracket, and a fastening mechanism between the connecting bracket and the bumper body. The fastening mechanism includes a fastening claw assembly at one end of the connecting bracket, a fastening groove on the fastening claw assembly, and a fastening post on the bumper body located at a corresponding position on the fastening claw assembly. When the bumper body rotates towards the connecting bracket, the fastening post extends into the fastening groove, causing the bumper body to snap onto the connecting bracket. This application, by providing a rotatable bumper body and fastening mechanism, allows the bumper body to flip, avoiding interference with the engine hood. The engine hood can be opened without disassembly, significantly reducing truck maintenance costs, improving repair efficiency and customer satisfaction. It has the advantages of reasonable structure, convenient operation, and strong practicality, making it easy to promote and implement.

[0026] In this embodiment, the fastening mechanism 3 further includes a connecting seat 7 located at one end of the connecting bracket 1, and the fastening claw group 4 includes a plurality of fastening claws 40, which are spaced apart along the length of the connecting seat 7.

[0027] In actual implementation, when it is necessary to open the engine hood of a large truck, the user applies a rotational force to the guardrail body 2 in a direction away from the connecting bracket 1. During the rotation, the fastening post 6 gradually disengages from the fastening groove 5, thereby causing the guardrail body to rotate away from the connecting bracket, thus preventing subsequent interference between the engine hood and the guardrail body.

[0028] In actual implementation, the design of multiple locking claws 40 increases the stability of the guardrail body 2 in the locked state. The combined action of multiple locking points (the cooperation of locking pins 6 and locking grooves 5) ensures that the guardrail body 2 can be firmly fixed to the connecting bracket 1 during vehicle operation, and is not easily loosened due to vehicle bumps or collisions.

[0029] In this embodiment, the fastening mechanism 3 further includes a rotating component 8 disposed between the fastening claw 40 and the connecting seat 7. The rotating component 8 includes a rotating shaft 80 disposed on the connecting seat 7 and a rotating hole 81 disposed at one end of the fastening claw 40. The rotating shaft 80 extends into the rotating hole 81 so that the fastening claw 40 rotates around the rotating shaft 80.

[0030] In actual implementation, by setting up a rotating component, the situation where the locking pin has difficulty extending into the locking groove can be effectively avoided. Since the locking claw 40 can rotate around the rotating shaft 80, this makes the unlocking and locking process of the guardrail body 2 smoother. Compared with the fixed locking structure, this rotatable locking claw design can better adapt to the movement of the guardrail body 2 at different angles, reduce jamming, and improve operational flexibility.

[0031] In actual implementation, the rotating assembly also includes a reset torsion spring on the rotating shaft. The reset torsion spring is used to drive the locking claw to rotate towards the locking post. By setting the reset torsion spring, the locking stability of the locking claw can be effectively improved.

[0032] In this embodiment, two locking claws 40 are spaced apart along the length of the connecting seat 7, and two locking claws 40 are directly provided with relief portions 41. When the guard bar body 2 rotates toward the connecting bracket 1, the guard bar body 2 matches and extends into the relief portion 41.

[0033] In this embodiment, a buffer ring 20 is also provided on the main body 2 of the guardrail at the position corresponding to the clearance portion 41.

[0034] In actual implementation, by setting up clearance parts and buffer rings, it is possible to effectively prevent the guardrail body from impacting the connecting bracket during the flipping process, thus effectively extending the service life of the guardrail body and the connecting bracket.

[0035] In this embodiment, the material of the buffer ring 20 is selected from any one of rubber, sponge, and foam.

[0036] In actual implementation, the buffer ring is made of rubber.

[0037] In this embodiment, the fastening mechanism 3 further includes a limiting part 9 protruding from the fastening post 6 and a hook part 90 provided on the fastening groove 5. When the fastening post 6 is inserted into the fastening groove 5, the hook part 90 abuts against the limiting part 9 to restrict the fastening claw assembly 4 from rotating away from the fastening post 6.

[0038] In actual implementation, when the guardrail body 2 rotates towards the connecting bracket 1 and the fastening pin 6 extends into the fastening groove 5, the hook 90 abuts against the limiting part 9. At this time, the hook 90 and the limiting part 9 interact, restricting the rotation of the fastening claw assembly 4 away from the fastening pin 6, thus firmly locking the guardrail body 2 onto the connecting bracket 1. When unlocking is required, simply apply sufficient external force to overcome the resistance between the hook 90 and the limiting part 9, causing the fastening claw assembly 4 to rotate away from the fastening pin 6, thereby disengaging the fastening pin 6 from the fastening groove 5 and enabling the guardrail body 2 to be flipped and unlocked.

[0039] In actual implementation, by setting limit parts and hook parts, the fastening stability is effectively enhanced, providing a more reliable mechanical guarantee for locking the main body 2 of the guardrail, effectively preventing the main body 2 of the guardrail from accidentally coming loose during vehicle operation, and improving driving safety.

[0040] In this embodiment, the guard bar body 2 includes a lower guard bar body 21 and an upper guard bar body 22 disposed on the lower guard bar body 21, and the connecting bracket 1 is rotatably connected to the lower guard bar body 21.

[0041] This application provides a flip-up front bumper for large trucks, comprising a connecting bracket, a bumper body rotatably mounted on the other end of the connecting bracket, and a fastening mechanism between the connecting bracket and the bumper body. The fastening mechanism includes a fastening claw assembly at one end of the connecting bracket, a fastening groove on the fastening claw assembly, and a fastening post on the bumper body located at a corresponding position on the fastening claw assembly. When the bumper body rotates towards the connecting bracket, the fastening post extends into the fastening groove, causing the bumper body to snap onto the connecting bracket. This application, by providing a rotatable bumper body and fastening mechanism, allows the bumper body to flip, avoiding interference with the engine hood. The engine hood can be opened without disassembly, significantly reducing truck maintenance costs, improving repair efficiency and customer satisfaction. It has the advantages of reasonable structure, convenient operation, and strong practicality, making it easy to promote and implement.
