Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically a split-assembly type front bumper. Background Technology
[0002] Car bumpers are safety devices that absorb and mitigate external impacts, protecting the front and rear of the vehicle. Located in most areas at the front and rear of the car, they are designed to prevent external damage from affecting the vehicle's safety systems. They have the ability to reduce injuries to occupants in high-speed collisions and are increasingly designed for human protection. The front bumper is installed at the front of the car, and people have increasingly higher requirements for the safety and appearance of the car's front bumper.
[0003] Regarding the aforementioned technologies, the applicant believes that a front bumper could utilize its own structure to buffer the impact force after a collision, protecting occupants and reducing injury. However, in practice, while existing bumpers do absorb some energy in low-speed impacts, their strong structural integrity and the integrated design of the bumper guard and buffer components mean that even minor damage necessitates replacing the entire bumper, increasing vehicle repair frequency and operating costs. Utility Model Content
[0004] The purpose of this utility model is to provide a split-assembly front bumper to solve the problem mentioned in the background art that, in use, existing bumpers, although they have a certain energy absorption capacity, have a strong overall structure and the front cover and buffer components are often integrated, which means that when there is only a small area of damage, the entire bumper must be replaced, increasing the frequency of vehicle maintenance and usage costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a split-assembly front bumper, including a main bumper and an energy-absorbing mechanism. The energy-absorbing mechanism is disposed inside the main bumper and includes a component slot opened in the middle part of the main bumper. An energy-absorbing spring is disposed at one end of the component slot, and a movable plate is disposed at one end of the energy-absorbing spring. A connecting rod is disposed at the end of the movable plate away from the energy-absorbing spring. An mounting sleeve is sleeved on the outside of the connecting rod, and a mounting block is disposed through the inside of the mounting sleeve. A protective plate is disposed at the end of the mounting block away from the main bumper, and protective pads are evenly disposed at the end of the protective plate away from the main bumper.
[0006] By adopting the above technical solution, when the device is subjected to a low-speed impact, the external impact force first acts on the protective plate, pushing the protective plate towards the main bumper. During the movement, the energy-absorbing spring first absorbs 30% to 40% of the impact energy through compression deformation. The remaining energy is further buffered by the protective pad through compression deformation. Together, they can absorb 60% to 70% of the total impact energy, reducing the load transmitted to the main bumper to within the material's elastic limit. This effectively prevents damage such as cracks, edge breakage, or connection detachment from the main and side bumpers, significantly reducing maintenance frequency, extending the service life of the main and side bumpers, and reducing long-term operating costs. When the protective plate is damaged, the mounting sleeve can be rotated to separate it from the connecting rod, making it easy to remove the mounting sleeve from the outside of the connecting rod and facilitating the maintenance and replacement of the protective plate.
[0007] Preferably, the protective plate is made of modified glass fiber material.
[0008] By adopting the above technical solution, the device can withstand external impact force during low-speed impacts, providing basic support for the subsequent energy-absorbing springs and protective pads to buffer energy, while also adapting to the needs of moving the protective plate and preventing premature damage.
[0009] Preferably, the protective pads are provided in three sets, and the protective pads are symmetrically distributed about the center point inside the protective plate.
[0010] By adopting the above technical solution, the impact force can be easily absorbed.
[0011] Preferably, the protective pad is made of foam.
[0012] By adopting the above technical solutions, the protective plate can be effectively protected.
[0013] Preferably, an inspection cover is provided at the top of the inside of the accessory slot.
[0014] By adopting the above technical solution, the internal parts of the parts slot can be easily inspected and repaired by opening the inspection cover.
[0015] Preferably, the main bumper has mounting grooves evenly distributed at both ends, and a mounting seat is disposed through the mounting groove. A side bumper is disposed at the end of the mounting seat away from the main bumper.
[0016] By adopting the above technical solution, the main bumper and the side bumper can be easily fixed together.
[0017] Preferably, the side bumper also has an accessory slot inside, and the mounting block is provided in three sets.
[0018] By adopting the above technical solution, the protective plate can be easily supported, thus improving its stability during operation.
[0019] Preferably, fixing bolts are provided at both ends inside the main bumper, and the fixing bolts pass through the interior of the main bumper and the mounting base respectively.
[0020] By adopting the above technical solution, the mounting base can be easily removed from the mounting groove by removing the fixing bolts, making it easy to disassemble and assemble the main bumper and side bumper.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] Equipped with an energy-absorbing mechanism, protective plate, accessory slot, and main bumper, the device can push the protective plate towards the main bumper when subjected to low-speed impact. The energy-absorbing spring and protective pad work together to absorb the impact force, minimizing damage to the main bumper and extending the device's service life. If the protective plate is damaged, the mounting sleeve can be rotated to separate it from the connecting rod, allowing the mounting sleeve to be easily removed from the outside of the connecting rod for convenient maintenance and replacement of the protective plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1
[0030] Please see Figures 1 to 4 This embodiment provides a technical solution: a split-assembly front bumper, including a main bumper 3 and an energy-absorbing mechanism 1.

A connecting rod 103 is provided at the end of the movable plate 106 away from the energy-absorbing spring 105. An installation sleeve 108 is sleeved on the outside of the connecting rod 103. The installation sleeve 108 is threadedly connected to the connecting rod 103. By rotating the installation sleeve 108, the installation sleeve 108 can be separated from the connecting rod 103, which can be easily removed from the outside of the connecting rod 103, and the protective plate 101 can be easily repaired and replaced.
[0032] The mounting sleeve 108 has a through mounting block 107 inside. A protective plate 101 is provided at the end of the mounting block 107 away from the main bumper 3. The protective plate 101 is made of modified glass fiber material, which has good impact resistance and structural strength. It can withstand the external impact force in low-speed impacts and provide basic support for the energy buffer of the subsequent energy-absorbing spring 105 and protective pad 102. At the same time, it is adapted to the use needs of moving the protective plate 101 to avoid premature damage.
[0033] The protective plate 101 is provided with protective pads 102 evenly distributed at one end away from the main bumper 3. The protective pads 102 are made of foam and there are three sets of protective pads 102. The protective pads 102 are symmetrically distributed about the center point inside the protective plate 101. The side bumper 2 is also provided with accessory slots 104 and there are three sets of mounting blocks 107.
[0034] The overall effect of this embodiment is as follows: When the device is subjected to a low-speed impact, the external impact force first acts on the protective plate 101, pushing the protective plate 101 towards the main bumper 3. During the movement, the energy-absorbing spring 105 first absorbs 30% to 40% of the impact energy through compression deformation. The remaining energy is further buffered by the protective pad 102 through compression deformation. Together, they can absorb 60% to 70% of the total impact energy, reducing the load transmitted to the main bumper 3 to within the material's elastic limit. This effectively prevents damage such as cracks, edge breakage, or connection detachment from the main bumper 3 and side bumper 2, significantly reducing maintenance frequency, extending the service life of the main bumper 3 and side bumper 2, and reducing long-term operating costs. When the protective plate 101 is damaged, the mounting sleeve 108 can be rotated to separate it from the connecting rod 103, making it easy to remove the mounting sleeve 108 from the outside of the connecting rod 103, and facilitating the maintenance and replacement of the protective plate 101.
[0035] Example 2
[0036] Based on Embodiment 1, mounting grooves 5 are evenly provided at both ends of the main bumper 3. Mounting seats 4 are provided through the inside of the mounting grooves 5.

The fixing bolts 6 pass through the inside of the main bumper 3 and the mounting seat 4 respectively, which can facilitate the fixing of the mounting seat 4 and facilitate the installation of the side bumper 2 at both ends of the main bumper 3.
[0037] The effect achieved by the entire second embodiment is that by removing the fixing bolts 6, the mounting base 4 can be easily removed from the mounting groove 5, and the main bumper 3 and the side bumper 2 can be easily disassembled and assembled.
[0038] Working principle: When the device is subjected to a low-speed impact, the external impact force first acts on the protective plate 101, pushing the protective plate 101 to move towards the main bumper 3. During the movement, the energy-absorbing spring 105 first absorbs 30% to 40% of the impact energy through compression deformation. The remaining energy is further buffered by the protective pad 102 through compression deformation. Together, they can absorb 60% to 70% of the total impact energy, reducing the load transmitted to the main bumper 3 to within the material's elastic limit. This can effectively prevent damage such as cracks, edge breakage, or connection detachment from the main bumper 3 and side bumper 2, significantly reducing the frequency of maintenance, extending the service life of the main bumper 3 and side bumper 2, and reducing long-term operating costs.
[0039] Secondly, when the protective plate 101 is damaged, the mounting sleeve 108 can be rotated to separate it from the connecting rod 103, making it easy to remove the mounting sleeve 108 from the outside of the connecting rod 103, and thus making it easy to repair and replace the protective plate 101.
