Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a rear bumper with a protective mechanism. Background Technology

[0002] The rear bumper is an important safety component and body panel installed at the rear of a car. Currently, most car rear bumpers are made of plastic.

[0003] In practical applications, when reversing, drivers are prone to low-speed, small-area contact or scraping with low walls, pillars, curbs, other vehicles' bumpers, or protrusions due to limited visibility or slight misjudgment of the distance to obstacles behind them. While such contact is not enough to cause the bumper to fail or deform completely, it can still cause some wear, dents, etc. Traditional car bumpers can only be repaired or replaced after damage, which is time-consuming and laborious. Therefore, there is an urgent need for a rear bumper with a protective mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rear bumper with a protective mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rear bumper with a protective mechanism includes a support beam, one end of which is connected to an outer protective plate. An assembly groove is provided on the outer side of the outer protective plate to install a mounting plate. The middle part of the mounting plate is recessed inward and presses against a foam board installed inside the assembly groove. Multiple slots are provided in the middle part of the mounting plate to engage and install a floating plate. The floating plate protrudes from the outer protective plate.

[0007] The outer wall of the floating plate is provided with multiple staggered protrusions. The protrusions are inserted into the insertion holes in the middle of the mounting plate. The protrusions have through holes in the middle and rubber columns are embedded therein. Fastening bolts are inserted through the middle of the rubber columns. The other end of the fastening bolts is screwed to the inner wall of the insertion hole. The fastening bolts and rubber columns are in pressure contact.

[0008] In addition, a preferred structure is that the outer protective plate has an inwardly recessed buffer groove in the middle, the buffer groove is used to connect with the middle protrusion of the mounting plate, and a foam board is installed in the buffer groove.

[0009] In addition, a preferred structure is that a groove is provided on one side of the mounting plate, and multiple slots are provided at the four corners of the groove and in the middle of the groove wall. The slots are connected to multiple buckles provided on the outside of the floating plate.

[0010] In addition, in a preferred configuration, a buffer rubber pad is installed between the mounting plate and the floating plate, and a plurality of rubber protrusions are provided in the middle of the buffer rubber pad, with both the mounting plate and the floating plate in compression contact with the outer wall of the buffer rubber pad.

[0011] In addition, a preferred structure is that the middle of the insertion hole is provided with a threaded hole for screwing in a fastening bolt.

[0012] Furthermore, in a preferred configuration, the bolt head of the fastening bolt is in compression contact with the protruding post and the rubber post, respectively.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, a detachable floating plate is installed at the common collision location of the rear bumper. After a low-speed impact, the floating plate disperses the force through internal components such as foam and buffer rubber pads to achieve a protective effect. Furthermore, during the subsequent disassembly and maintenance of the floating plate, it can be quickly disassembled and reassembled simply by removing the components with bolts, which significantly improves the overall protective effect and maintenance efficiency of the bumper.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A rear bumper with a protective mechanism includes a support beam 1, one end of which is connected to an outer protective plate 2. An assembly groove 21 is provided on the outer side of the outer protective plate 2 to install an mounting plate 4. The middle part of the mounting plate 4 is recessed inward and presses against a foam board 23 installed inside the assembly groove 21. A plurality of slots 41 are provided in the middle of the mounting plate 4 to engage and install a floating plate 3. The floating plate 3 protrudes from the outer protective plate 2 to provide a protective effect.

[0023] The outer wall of the floating plate 3 is provided with a plurality of staggered protrusions 32. The protrusions 32 are inserted into the insertion holes 42 in the middle of the mounting plate 4. The protrusions 32 have through holes in the middle and rubber columns 51 are embedded therein. Fastening bolts 5 are inserted through the middle of the rubber columns 51. The other end of the fastening bolts 5 is screwed to the inner wall of the insertion holes 42. The fastening bolts 5 and the rubber columns 51 are in contact by compression.

[0024] The outer protective plate 2 has an inwardly recessed buffer groove 22 in the middle. The buffer groove 22 is used to connect with the middle protrusion of the mounting plate 4. A foam board 23 is installed in the buffer groove 22, and the foam board 23 absorbs the impact force.

[0025] A groove is provided on one side of the mounting plate 4. Multiple slots 41 are provided at the four corners of the groove and in the middle of the groove wall. The slots 41 are engaged with multiple buckles 31 provided on the outside of the floating plate 3. The connection between the buckles 31 and the slots 41 is achieved to ensure basic connection stability.

[0026] A buffer rubber pad 6 is installed between the mounting plate 4 and the floating plate 3. Multiple rubber protrusions are provided in the middle of the buffer rubber pad 6. Both the mounting plate 4 and the floating plate 3 are in contact with the outer wall of the buffer rubber pad 6 by compression. The relative displacement of the floating plate 3 after being impacted is satisfied by the deformation of the buffer rubber pad 6.

[0027] A threaded hole is provided in the middle of the insertion hole 42 for screwing in and fastening bolt 5.

[0028] The bolt head of the fastening bolt 5 is pressed into contact with the protruding post 32 and the rubber post 51 respectively, thereby pressing the floating plate 3 onto the mounting plate 4. Since there is no rigid connection between the floating plate 3 and the fastening bolt 5, the floating plate 3 can still move a certain distance after being subjected to impact force.

[0029] In this embodiment, the floating plate 3 protrudes slightly from the outer protective plate 2 to provide protection. The floating plate 3 is located in the middle of the outer protective plate 2 and effectively protects the middle and both sides. When the rear bumper is subjected to a low-speed impact, the object will first come into contact with the protruding floating plate 3. The floating plate 3 is subjected to force and shifts inward, causing the internal buffer rubber pad 6 to deform to absorb the force. At the same time, the force will be transmitted to the mounting plate 4 and the outer protective plate 2. During this process, the foam board 23 can further disperse the force and prevent the outer protective plate 2 from deforming.

[0030] For scratches and dents caused by impact to the floating plate 3, the floating plate 3 can be disassembled by removing the fastening bolts 5 and taking the floating plate 3 out of the mounting plate 4. Due to the detachable nature and small size of the floating plate 3, it is more convenient to maintain and replace it in the later stage. Compared with directly replacing or repairing the outer protective plate 2, it is a direct and considerable improvement. The cost of replacing or repairing the floating plate 3 is smaller and more convenient.

[0031] The floating plate 3 is set in the common collision areas of the outer protective plate 2, namely the center and both sides.

[0032] The connection method and installation process of the support beam 1 and the outer protective plate 2, i.e. the rear bumper and the car, are common knowledge to those skilled in the art and will not be explained further.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
