If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0035] The bumper is a safety device that absorbs and reduces external impact forces and protects the front and rear parts of the vehicle body. It is generally distributed at the front and rear ends of the vehicle body and is mostly made of materials with relatively high elasticity such as plastic and resin. The surface is sprayed using a computerized painting process to create a matte or mirror finish, enhancing the texture of the front and rear of the vehicle while protecting it and improving the integrity and coordination with the vehicle body. In the relevant prior art, the bottom of the bumper is connected to a boss nut welded on the body sheet metal bracket by bolts. During the disassembly and assembly process, an electric wrench is used to install or remove the bolts, and the surface coating of the bolts is easily damaged. Since the bottom of the bumper is located in the wet area of the whole vehicle, the bolts are prone to rusting. With the increasing requirements of the market for automobiles, the rusting of the bolts at the bottom of the bumper will affect the overall visual perception of the vehicle body workmanship in the market and the evaluation of the vehicle body quality and durability.

[0036] Therefore, the present utility model proposes an installation structure for the bottom of the bumper, which can avoid the problem of bolt rusting, thereby improving the overall design and quality of the vehicle.

[0037] Referring to Figure 1 and Figure 2 In the installation structure for the bottom of the bumper according to the embodiment of the present utility model, it includes a bumper main body 100 and a bracket 200. The bracket 200 is installed on the vehicle body, and a clamping hole position 203 is provided at the lower end position of the bracket 200. A clamping structure 300 is provided at the bottom of the bumper main body 100. A protruding portion 303 is provided on the periphery of the clamping structure 300, and the protruding portion 303 is configured as a structure that can be pressed and contracted, that is, it can be pressed and contracted toward the clamping structure 300 under an external force. Among them, the clamping structure 300 is assembled in the clamping hole position 203 and is clamped by the protruding portion 303. When the protruding portion 303 is pressed by an external force, it can be contracted, so that the clamping structure 300 can be disengaged from the clamping hole position 203.

[0038] The orientation description in this embodiment is based on the vehicle body coordinate system. For example, the connection hole position is provided at the lower end of the bracket 200, which means that after the bracket 200 is installed on the vehicle body, the connection hole position is located at the lower end position of the bracket 200. Correspondingly, the clamping structure 300 also refers to the orientation when the bumper main body 100 is assembled on the vehicle body and is located at the bottom of the bumper main body 100.

[0039] It can be understood that for the bottom mounting structure of the bumper in the present utility model, the bottom of the bumper main body 100 is mounted and supported by arranging a bracket 200 on the vehicle body to ensure the mounting stability of the bumper main body 100. The number of brackets 200 can be flexibly set according to the mounting strength requirements, and is not limited to one. For example, multiple brackets 200 are arranged along the length direction of the bumper main body 100 for support. In the present utility model, the bumper main body 100 is provided with a clamping structure 300 at the bottom, and the clamping structure 300 is used to clamp the clamping hole positions 203 on the bracket 200, replacing the bolts in the traditional solution. Therefore, the problem of bolt corrosion can be avoided, and the design and quality of the whole vehicle can be improved. Moreover, the protruding part 303 on the clamping structure 300 can be pressed and contracted by an external force, so that the clamping structure 300 can be disengaged from the clamping hole position 203, which is convenient for disassembly, and is beneficial to improving the disassembly and assembly efficiency of the bumper main body 100, reducing the labor cost, and reducing the production tools.

[0040] In some embodiments of the present utility model, the clamping structure 300 and the bumper main body 100 are connected as an integral structure. Since the clamping structure 300 is the acting point on the bumper main body 100 for connecting the bracket 200, the clamping structure 300 plays an important role in the mounting stability of the bumper main body 100. Integrally arranging the clamping structure 300 on the bumper main body 100 is beneficial to improving the production efficiency and avoiding abnormal noises between the clamping structure 300 and the bumper main body 100.

[0041] Furthermore, the material strength of the clamping structure 300 is configured to be greater than that of the bumper main body 100, that is, the material of the clamping structure 300 is higher in strength than that of the bumper main body 100. This can effectively ensure the stress strength of the clamping structure 300 and avoid damage to the clamping structure 300 during multiple disassembly and assembly processes. Moreover, the production cost can be controlled while ensuring the support strength of the clamping structure 300 for the bumper main body 100, and the material cost of the bumper main body 100 can be prevented from being too high.

[0042] Specifically, the bumper main body 100 is made of PP + EPDM-T20, and the clamping structure 300 is made of modified PP + glass fiber, such as PP-GF30, PP-GF50, etc. In actual production, the bumper main body 100 and the clamping structure 300 can be injection-molded in two colors.

[0043] Refer to Figure 3, in some embodiments of the present utility model, the clamping structure 300 includes a plug 302 that matches the aperture of the clamping hole 203, and a protrusion 303 is provided on the circumferential side of the plug 302. With the structural arrangement of this embodiment, when the bumper main body 100 is installed, the plug 302 is aligned with the clamping hole 203 and inserted until the protrusion 303 is partially or completely located on the other side of the clamping hole 203, then the clamping installation can be completed; during disassembly, the worker presses the protrusion 303 from the side of the plug 302, and then pushes the plug 302 outwards to complete the disassembly.

[0044] Referring to Figures 3 to 5 , in some embodiments of the present utility model, relief openings 3021 are provided on opposite sides of the plug 302, and the clamping structure 300 is provided with two protrusions 303, and the two protrusions 303 are respectively located in the two relief openings 3021. Since the plug 302 is adapted to the aperture of the clamping hole 203, if the protrusion 303 is connected to the outer wall of the plug 302, it is difficult for the protrusion 303 to pass through the clamping hole 203 during the disassembly and assembly process. In this embodiment, the relief openings 3021 are used to accommodate the protrusions 303, which facilitates the protrusions 303 to pass through the clamping hole 203 for clamping, and can improve the convenience of disassembly and assembly while ensuring that the plug 302 fits against the inner wall of the clamping hole 203.

[0045] Furthermore, referring to Figure 4 and Figure 5 , along the axial direction of the plug 302, one end of the protrusion 303 away from the bumper main body 100 is connected to the side wall of the relief opening 3021, and one end of the protrusion 303 close to the bumper main body 100 protrudes outside the plug 302. For the convenience of understanding, it is set that one end of the protrusion 303 away from the bumper main body 100 is the first end, and one end of the protrusion 303 close to the bumper main body 100 is the second end. In this embodiment, the second end of the protrusion 303 is suspended, making the protrusion 303 form a cantilever structure. Based on the material properties of the protrusion 303 itself, the second end can be pressed under an external force to contract towards the relief opening 3021 around the first end, so that the part of the protrusion 303 protruding from the surface of the plug 302 contracts inwards, facilitating disassembly. It can be understood that during the installation stage, when the plug 302 is inserted into the clamping hole 203, the bracket 200 moves relative to the plug 302 in the direction from the first end to the second end, and the slope formed by the length direction of the protrusion 303 can be used to press the protrusion 303, thereby completing the installation. During the disassembly stage, the protrusions 303 are located on opposite sides of the plug 302, and the worker can directly press the two protrusions 303 to retract their protruding parts into the relief openings 3021, so that the plug 302 can be pushed outwards.

[0046] Referring to Figures 3 to 5In some embodiments of the utility model, a clearance hole 3022 is provided at the axis of the latch 302, and the clearance opening 3021 penetrates the side wall along the radial direction of the latch 302 and communicates with the clearance hole 3022. The end of the protrusion 303 close to the axis of the latch 302 is located on the same circumference as the inner wall of the clearance hole 3022. With the structural setting of this embodiment, firstly, the clearance hole 3022 can be used to reduce weight and reduce material usage, and secondly, the clearance hole 3022 can provide a shrinkage space for the protrusion 303 to shrink inward. In addition, this embodiment uses the clearance hole 3022 to provide a shrinkage space for the protrusion 303, which can prevent the protrusion 303 from protruding too much outward and causing the protrusion 303 to break during the disassembly process. The size of the latch pin 302 can be perfectly matched with the snap-in hole 203, and there is no need to appropriately reduce the size in order to allow the protrusion 303 to smoothly pass through the snap-in hole 203. Therefore, the structural setting of this embodiment is conducive to taking into account both the installation stability between the snap-in structure 300 and the bracket 200 and the convenience of disassembly of the snap-in structure 300.

[0047] Reference Figure 4 and Figure 5 , one end of the protrusion 303 away from the axis of the plug 302 protrudes outward from the surface of the plug 302. Specifically, at the first end, the side wall of the protrusion 303 is connected to the outer side wall of the plug 302, and along the direction toward the second end, the side wall of the protrusion 303 gradually protrudes in the direction away from the axis of the plug 302. In this way, when the plug 302 is inserted into the engaging hole 203, the side wall of the engaging hole 203 can slide along the outer side wall of the protrusion 303, automatically pressing and shrinking the protrusion 303 to complete the engaging.

[0048] It should be noted that, when the installation dimensions are met, the protrusion 303 may also be provided on the telescopic structure so that it can be extended out of the latch 302 and retracted into the latch 302 by telescoping.

[0049] Reference Figures 3 to 5 In some embodiments of the present invention, a chamfered structure is provided at the end of the plug 302. Since the outer diameter of the plug 302 is the same as the hole diameter of the engaging hole 203, it is difficult to insert the plug directly. In this embodiment, by providing a chamfered structure, the plug 302 can be pre-positioned and guided when it is inserted into the engaging hole 203, so that the plug 302 can be smoothly and quickly inserted into the engaging hole 203, thereby improving the installation efficiency.

[0050] Reference Figure 3 , Figure 5, in some embodiments of the present utility model, the clamping structure 300 further includes a support plate 301. The support plate 301 is connected to the bottom of the bumper body 100, and the plug pin 302 is arranged on the end face of the support plate 301. Usually, the bumper body 100 is an arc-shaped structure matching the body shape, and in the present utility model, a material with a structural strength greater than that of the bumper body 100 is used to form the clamping structure 300. Therefore, a support plate 301 is provided to facilitate the formation of the plug pin 302 and also facilitate the docking with the bracket 200. Opposite to the support plate 301, an installation plate 201 is provided at the bottom of the bracket 200. The plate surface of the installation plate 201 is opposite to the plate surface of the support plate 301, and the clamping hole position 203 is arranged on the installation plate 201. With the structural arrangement of this embodiment, it is convenient for the clamping structure 300 to be integrally formed with the bumper body 100. Compared with the method of directly forming the plug pin 302 on the bumper body 100, it is more beneficial to improve the support strength of the clamping structure 300 for the bumper body 100. At the same time, the plate surface orientation of the support plate 301 can be adjusted according to the installation situation, so as to adjust the axial direction of the plug pin 302, facilitating the insertion of the plug pin 302 into the clamping hole position 203.

[0051] Referring to Figure 1 、 Figure 3 , with the body coordinate system as a reference, the upper end of the support plate 301 is connected to the lower edge of the bumper body 100, and the lower end of the support plate 301 extends backward obliquely to reduce wind resistance. The left and right ends of the support plate 301 are consistent with the left and right directions of the bumper body 100 at the connection. And the support plate 301 is arranged at the position where the bumper body 100 extends left and right. It can be understood that there may be parts of the bumper body 100 that extend forward and backward on the vehicle body, such as the areas on both sides of the vehicle body. In this embodiment, by arranging the support plate 301 in the area where the bumper body 100 extends left and right relative to the vehicle body, the plate surface of the support plate 301 and the plate surface of the installation plate 201 are opposite front and back along the body coordinate system. In this way, when the bumper body 100 is assembled along the front and back directions of the vehicle body, the plug pin 302 will automatically insert into the clamping hole position 203, which can greatly improve the disassembly and assembly efficiency of the bumper body 100. Compared with the traditional method of using an electric wrench to disassemble and assemble bolts, it not only improves the disassembly and assembly convenience but also reduces the use of tools.

[0052] It can be understood that the support plate 301 and the installation plate 201 extend downward by a certain distance, so they are visible at the bottom of the vehicle body. During the assembly process, the staff can observe from the bottom of the vehicle body to judge whether the installation is in place. Specifically, it can be checked from the back of the installation plate 201 to see whether the protrusion 303 is fully opened and clamped on the back of the installation plate 201, so as to judge whether the plug pin 302 is inserted in place.

[0053] Referring to Figure 4 and Figure 7, in some embodiments of the present utility model, a top holding structure is provided at one end of the mounting plate 201 close to the support plate 301. The top holding structure is a boss 202 provided in a circle around the clamping hole position 203. The size of the boss 202 is such that when the bolt 302 is inserted in place and the protruding portion 303 is clamped to the back surface of the mounting plate 201, the support plate 301 is top held. With the structural arrangement of this embodiment, by top holding the support plate 301 with the boss 202, the gap between the bolt 302 and the support plate 301 can be eliminated, avoiding abnormal noise caused by the existence of the gap. Moreover, compared with the limiting method of fitting and abutting the mounting plate 201 and the support plate 301, it is easier to implement and can effectively improve the fastening property of the clamping of the bolt 302.

[0054] It can be understood that the top holding structure can also be provided on the support plate 301.

[0055] Refer to Figures 1 to 7 , in some embodiments of the present utility model, the bumper bottom mounting structure includes a bumper main body 100 and a bracket 200. The upper end of the bracket 200 is connected to the vehicle body, and a mounting plate 201 is provided at the lower end extending downward. The bracket 200 is an overall sheet metal structure to ensure structural strength. A clamping hole position 203 is opened on the end surface of the mounting plate 201. At the same time, relative to the vehicle body coordinate system, a boss 202 is provided in a circle around the clamping hole position 203 on the front end surface of the mounting plate 201. A plurality of support plates 301 are provided at the bottom of the bumper main body 100 along the length direction. A bolt 302 is provided on the back surface of the support plate 301. A relief hole 3022 is opened at the axis center of the bolt 302. At the same time, two relief openings 3021 are symmetrically arranged around the axis on the side wall of the bolt 302. A protruding portion 303 is provided in each of the two relief openings 3021 of the bolt 302. Along the length direction of the bolt 302, one end of the protruding portion 303 away from the bumper main body 100 is connected to the inner wall of the relief opening 3021, thereby forming a cantilever structure. The outer side wall of the protruding portion 303 gradually protrudes outward along the direction close to the bumper main body 100. The structure of the bumper main body 100 is made of PP + EPDM-T20, the support plate 301, the bolt 302 and the protruding portion 303 are made of PP-GF30, and the bumper main body 100 is integrally formed by two-color injection molding. The upper end of the support plate 301 extends upward a certain distance relative to the lower edge of the bumper main body, and at the same time, reinforcing ribs 3011 are provided along the peripheral edge position of the front surface of the support plate 301 to improve the structural strength of the support plate 301.

[0056] With the structural arrangement of this embodiment, taking the bumper at the front end of the vehicle body as an example, during the installation process of the bumper body from front to back, the pin 302 at the bottom will automatically insert into the clamping hole 203 to complete the installation. The staff only needs to press the bumper body 100 at the corresponding position to ensure that the pin 302 is inserted in place, and the installation is convenient. After installation, the protrusion 303 protrudes outward relative to the pin 302, so as to be clamped to the back of the mounting plate 201. At the same time, the front of the mounting plate 201 abuts against the support plate 301 through the boss 202, which can effectively ensure the connection stability between the mounting plate 201 and the support plate 301. When disassembly is required, only need to press the two protrusions 303 from the back of the mounting plate 201 to push the pin 302 forward.

[0057] Adopting the two-color injection molding process is beneficial to improving production efficiency. Among them, the support plate 301, the pin 302 and the protrusion 303 are made of PP-GF30, which can improve strength and durability. The bracket 200 can effectively support the bumper body 100 through the pin 302. The bumper body 100 and the bracket 200 are clamped through the pin 302, canceling the bolt connection, which can prevent the problem of bolt rust caused by repeated disassembly. At the same time, the pin 302 is located on the back of the support plate 301, which is a hidden design, and the appearance of the bumper body 100 looks more flat, which helps to improve the appearance refinement. At the same time, the disassembly and assembly process is more simple, which can improve the production rhythm of the whole vehicle and reduce the production cost. The pin 302 is clamped by the protrusions 303 on both sides, and the clamping strength is large, which can ensure the reliability of the installation. At the same time, after disassembly, there is no need to consider the situation of pin 302 loss or pin 302 damage, which can improve the after-sales maintenance efficiency and reduce the after-sales maintenance cost. Compared with the bolt installation method, the staff can directly judge whether the installation is in place through the protrusion 303, canceling the process of reinspecting the torque in bolt installation, which can improve the inspection efficiency.

[0058] The present utility model also proposes a vehicle, which applies the bumper bottom installation structure of any one of the above embodiments. The vehicle can be a private car, such as a sedan, an SUV, an MPV or a pickup truck, etc. The vehicle can also be an operating vehicle, such as a minibus, a bus, a small truck or a large trailer, etc. The vehicle can be an oil vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle. The bumper body 100 can be either a front bumper or a rear bumper.

[0059] By applying the above-mentioned mounting structure at the bottom of the bumper in the present utility model, the setting of bolts in the traditional solution is replaced, which can avoid the problem of bolt corrosion and improve the design and quality of the whole vehicle.
