[0001] This utility model relates to the field of bumper technology, and in particular to a bumper side decorative corner plate assembly. Background Technology
[0002] Currently, in conventional bumper assembly schemes, a doghouse structure is usually designed on the corner plate, and then the corner plate is assembled with the bumper body using bolts and spring nuts.
[0003] While this traditional connection method provides a certain degree of structural stability during the initial assembly phase, it reveals numerous drawbacks during later vehicle use. When the corner plate is damaged and requires repair or replacement, repair personnel typically need to remove the entire bumper from the vehicle body and then remove the bolts from the back of the bumper—a cumbersome and complex process. This process not only consumes a significant amount of time, substantially increasing repair and labor costs, but also, due to limited operating space during the complete removal of the bumper, may damage other parts of the vehicle, leading to secondary repairs, further burdening the owner, and reducing repair efficiency.
[0004] Therefore, it is necessary to improve the existing bumper side trim panel assembly. Utility Model Content
[0005] The purpose of this utility model is to overcome the defects existing in the prior art and provide a bumper side decorative corner plate assembly, which uses a snap-fit method to fix the corner plate body to the bumper body, making it easy to disassemble and assemble, saving time and effort.

[0032] Example 1
[0033] like Figure 1-9 As shown, the bumper side decorative corner plate assembly of the embodiment includes a bumper body 1 and a corner plate body 2. The bumper body 1 is provided with an assembly hole 11, and an elastic limiting member is provided in the assembly hole 11. The elastic force direction of the elastic limiting member is parallel to the radial direction of the assembly hole 11. The corner plate body 2 is provided with a limiting member, which is inserted and connected to the elastic limiting member. The limiting member includes a rod portion 41 and a limiting portion 42. The rod portion 41 passes through the elastic limiting member. The insertion end 421 and the pull-out end 422 of the limiting portion 42 are both provided with transition arc surfaces. The elastic limiting member is sandwiched between the limiting portion 42 and the corner plate body 2.
[0034] This design achieves the following objectives:
[0035] 1. Easy to disassemble and assemble, improving efficiency: By utilizing the snap-fit between the limiting male component and the elastic limiting component, and by providing transition arc surfaces at both the insertion and extraction ends of the limiting part, the corner plate body can be directly removed from the front of the bumper. Unlike the traditional method of disassembling the entire bumper, it also avoids the destructive insertion and removal of traditional snap-fit structures, greatly simplifying the operation process, saving disassembly and assembly time, and significantly improving maintenance efficiency.
[0036] 2. Reduced costs: The elimination of the need to completely disassemble the bumper reduces the workload during the repair process and lowers labor costs; at the same time, it avoids potential damage to other parts of the vehicle caused by complete disassembly, reducing the cost of secondary repairs and thus lowering overall repair costs.
[0037] According to one embodiment of the present invention, the elastic limiting member includes an EPDM rubber ring 3, and the EPDM rubber ring 3 is provided with a first limiting groove 31 that limits and cooperates with the assembly hole 11.
[0038] Elastic deformation can adapt to the insertion requirements: EPDM rubber (ethylene propylene diene monomer rubber) has good elasticity and flexibility, and its elastic force is parallel to the radial direction of the assembly hole. When the limiting male is inserted, the rubber ring can clamp the rod through radial elastic deformation, forming a stable snap-fit structure to ensure that the corner plate body and the bumper body are firmly connected and not easy to loosen.
[0039] Shock absorption performance: The rubber material can absorb vibration and impact during vehicle operation, reduce rigid collisions between the corner plate body and the bumper body, reduce the risk of wear or loosening of components due to long-term vibration, and extend the service life of components.
[0040] Simplified assembly process: The elastic properties of the EPDM rubber ring allow the insertion of the limiting male part without the need for complicated tools. The insertion can be completed smoothly by guiding it through the transition arc surface. During disassembly, only external force needs to be applied to deform the rubber ring, and the limiting male part can be pulled out, realizing the quick disassembly of the corner plate body.
[0041] Good reusability: EPDM rubber has excellent aging resistance and weather resistance. It can still maintain good elasticity and limiting performance after multiple disassembly and assembly. It is not easy to fail due to frequent use, which reduces maintenance costs and the frequency of parts replacement.
[0042] According to one embodiment of the present invention, the limiting component includes a ball-head iron part 4, and the limiting part 42 is spherically shaped.
[0043] Transitional arc surface guides and reduces assembly resistance: When the ball-head iron part is inserted into the EPDM rubber ring, the arc surface can guide the radial elastic deformation of the rubber ring, reduce insertion resistance, and make the assembly process smoother; during disassembly, the arc surface can also assist the rubber ring to deform, and it can be quickly pulled out without tools.
[0044] High impact resistance, preventing deformation and damage: The ball joint iron part is made of metal, which has high strength and good rigidity. It can withstand the impact of external forces on the corner plate body during vehicle operation, avoid the failure of the limiting part due to deformation under force, and ensure the reliability of the snap-fit structure during long-term use.
[0045] According to one embodiment of the present invention, the corner plate body 2 is fixedly provided with a mounting plate 21, the mounting plate 21 is provided with a mounting groove 211, and the ball head iron part 4 is provided with a second limiting groove 43 that is inserted and cooperates with the mounting groove 211.
[0046] The mounting slot is oriented in the first direction. The bottom surface of the corner plate body 2 and the bottom surface of the bumper body 1 are provided with matching inclined surfaces. The projection of the slope direction from high to low onto the horizontal plane is the second direction, which is opposite to the first direction. This can prevent the corner plate body and the ball joint from sliding and separating after assembly.
[0047] Mechanical limiting to prevent detachment: The insertion and engagement of the mounting slot and the second limiting slot form a "slot-locking" mechanical limiting structure. The second limiting slot of the ball joint is embedded in the mounting slot of the mounting plate, which can prevent the ball joint from axially displacing on the corner plate body, avoiding loosening or detachment of the ball joint due to vibration and impact during vehicle operation, and ensuring the reliability of the connection between the limiting component and the corner plate body.
[0048] Precise positioning simplifies the installation process: The shape and size of the mounting slot and the second limiting slot match each other, and the position of the ball head iron part can be quickly positioned by "plugging" during assembly without the need for additional tools or complex adjustments, thus improving assembly efficiency.
[0049] According to one embodiment of the present invention, the bumper body 1 is provided with a receiving groove 12 for accommodating the mounting plate 21.
[0050] Aesthetic consistency and integrity: The mounting plate is fixed to the corner plate body. When the corner plate body is engaged with the bumper body via the limiting maleic device, the mounting plate is embedded in the receiving groove, ensuring that the surface of the corner plate body is flush with the surface of the bumper body. This avoids any abrupt changes in appearance or height differences caused by exposed mounting plates. This design ensures the overall streamlined appearance of the bumper, meeting the aesthetic requirements of automotive components.
[0051] Enhanced torsional resistance of the connection structure: The fit between the receiving groove and the mounting plate forms a mechanical limit. When the corner plate body is subjected to external force, the groove wall of the receiving groove can limit the displacement of the mounting plate, thereby reducing the shaking or tilting of the corner plate body.
[0052] According to one embodiment of the present invention, the assembly hole 11 is arranged in a triangular shape with three parts, and the elastic limiting member and the limiting male member correspond one-to-one with the assembly hole 11.
[0053] The triangular support structure has strong resistance to deformation: the triangle is the most stable shape in geometric structure. When the three mounting holes are distributed in a triangle, a stable triangular support system can be formed. When the corner plate body is subjected to external force, the triangular layout can evenly distribute the force to the three mounting points, avoiding structural deformation or loosening caused by excessive force on a single point, and ensuring that the connection between the corner plate body and the bumper body always remains stable.
[0054] Multi-directional limiting to prevent corner plate swaying: The three mounting holes form multi-angle limiting in space (such as lateral, longitudinal, and diagonal), which can limit the displacement of the corner plate body in multiple dimensions (such as front-back, left-right, and up-down swaying). For example, when the corner plate is subjected to a side impact while the vehicle is in motion, the three limiting points of the triangular layout can work together to offset the impact force, preventing the corner plate body from tilting or falling off.
[0055] Example 2
[0056] like Figure 10-13 As shown, Example 2 is based on Example 1, except that a fixing component for fixing the EPDM position is provided between the EPDM rubber ring 3 and the bumper body 1.
[0057] Mechanical clamping and fixing position: The fixing component fixes the EPDM rubber ring in the assembly hole by clamping force to prevent it from being pulled away by the ball head iron part during insertion and removal.
[0058] Maintaining consistent force on the elastic limiting component: After the rubber ring is fixed, its radial elastic force direction is always parallel to the radial direction of the assembly hole, ensuring that the elastic deformation of the rubber ring is uniform and the clamping force is stable when the limiting component is inserted.
[0059] According to one embodiment of the present invention, the fixing component includes two clamping plates 5 disposed on both sides of the bumper body 1. The clamping plates 5 are provided with stepped grooves 51 that limit and cooperate with the EPDM rubber ring 3. An installation component for clamping the EPDM rubber ring 3 is provided between the two clamping plates 5.
[0060] The two clamping plates form a symmetrical clamping force: The two clamping plates are located on both sides of the bumper body. When clamped by the mounting components, they can generate symmetrical radial pressure on the EPDM rubber ring, making it fit tightly against the inner wall of the mounting hole and preventing the rubber ring from rotating circumferentially or sliding axially in the hole.
[0061] Supports independent replacement of rubber rings: When the rubber ring needs to be replaced, only the side plates and mounting components need to be removed to directly remove the old rubber ring and install the new one. There is no need to remove the corner plate body or the bumper body, which greatly reduces the amount of maintenance work.
[0062] According to one embodiment of the present invention, the mounting assembly includes a through hole 52 provided on the clamping plate 5, a through hole 13 provided on the bumper body 1, a bolt 6 passing through the through hole 52 and the through hole 13, and a nut 7 threadedly connected to the bolt 6. The two clamping plates 5 are clamped between the end of the bolt 6 and the nut 7.
[0063] Rigid connection enhances structural reliability: Bolts pass through the through holes in the clamping plates and the through holes in the bumper body, clamping the two clamping plates between the bolt ends and the nuts to form a rigid fixing structure. This design effectively suppresses the vibration displacement of the rubber ring during vehicle operation, preventing the insertion failure of the limiting male component and the rubber ring due to loosening, and ensuring a firm connection between the corner plate body and the bumper body.
[0064] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
