Description

Technical Field

[0001] This application relates to the technical field of automobiles, and more particularly to a bumper structure and vehicle. Background Technology

[0002] A car's structure comprises complex components such as the body, chassis, powertrain, and electronic systems. These parts work together to achieve functions like driving, safety, and comfort. The bumper, as a key component of a car, is primarily installed at the front and rear. It not only acts as a buffer in collisions, protecting the vehicle and pedestrians, but also enhances the overall aesthetic design of the vehicle. With the development of automotive intelligence, radar systems are widely used in cars for functions such as driver assistance and blind spot monitoring. Due to the bumper's location and structural characteristics, it has become an ideal location for installing radar systems.

[0003] Radars are typically fixed to brackets using self-tapping screws, and the brackets are then fixed to the bumper using self-tapping screws, making disassembly inconvenient. Currently, the structure for mounting radar on the bumper involves creating radar mounting holes in the bumper body, and incorporating a snap-fit ​​and a pivot part. A rotating block at one end of the radar cover is mounted onto the pivot, while the other end is snapped into the snap-fit ​​part, thus enabling radar installation and facilitating easy disassembly.

[0004] However, this existing structure still has many drawbacks. On the one hand, during vehicle operation, due to complex road conditions and frequent bumps and vibrations, the radar installation method, which relies solely on clips and hinges for connection, lacks sufficient installation stability and is prone to loosening or even detachment, affecting the normal operation of the radar and potentially threatening driving safety. On the other hand, to achieve radar installation, the radar plate and bumper body structures still need to be designed separately. This means that two sets of molds need to be developed, which not only increases product development costs but also prolongs the R&D cycle, hindering the company's cost control and market competitiveness. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a bumper structure and vehicle, with a new design for a radar fixing structure in the bumper body, to achieve detachable installation of existing radar and secure installation, requiring only a separate design of the bumper body structure, in order to solve the problems of insufficient installation stability and high development cost of existing detachable radar mounting structures on bumpers.

[0007] To achieve the above objectives, in a first aspect, this application provides a bumper structure, comprising:

[0008] Bumper body:

[0009] Limiting seat, the limiting seat is set on the bumper body;

[0010] A mounting base is provided on the bumper body; an installation space for accommodating the radar is provided between the mounting base and the limiting base;

[0011] The limiting component on one side of the radar is connected to the limiting seat, and the fixing component on the other side of the radar is connected to the fixing seat.

[0012] In existing technologies, radar housings typically have multiple outward-protruding connection points on their outer perimeter. Each connection point is fixed to a bracket using self-tapping screws, and the bracket is then fixed to the bumper using multiple self-tapping screws. This not only makes disassembly inconvenient but also requires separate molds for both the radar housing and the bracket, increasing costs. Furthermore, in existing detachable radar mounting structures, a notch is provided on the rotating block at one end of the radar cover. The rotating shaft on the bumper body is inserted into the notch, allowing the radar cover to be rotatably mounted on the bumper body. The other end of the radar cover is snapped onto the bumper body. Bumps and vibrations during vehicle operation can easily cause the snap to detach and the rotating shaft to come out of the notch on the rotating block, resulting in insufficient installation stability and a tendency to loosen or even fall off. Moreover, the radar cover still requires separate molds for manufacturing, keeping costs high. This application utilizes the aforementioned solution to directly employ the radar's housing structure, which is fixedly connected to the bracket via self-tapping screws. The connection point on one side of the radar housing serves as a limiting component, while the connection point on the other side acts as a fixing component. The radar is installed using a combination of limiting component insertion and fixing bolts. This achieves stable installation of the radar and facilitates disassembly and maintenance without requiring the removal of the entire bumper, thus improving the convenience and efficiency of repairs. Furthermore, the radar does not require a separate mold; the existing mold with self-tapping screws can be used for manufacturing, reducing mold costs and R&D cycles, which is beneficial for cost control and enhancing the company's market competitiveness.

[0013] In some embodiments of this application, the bumper body is provided with an assembly port and a wiring port; one end of the assembly port is connected to a cover plate, and the other end of the assembly port is snapped into the cover plate so that the cover plate closes the assembly port.

[0014] The wiring port is used to extend the wiring harness inside the bumper body to connect the wiring harness to the radar.

[0015] The width of the wiring port is smaller than that of the assembly port, and one end of the wiring port extends and connects to the assembly port.

[0016] In the technical solution, the structural design facilitates the passing of wire harnesses and their connection to the radar through the assembly port, while also organizing the cables into the connection port, thus improving the convenience of cable installation. On the other hand, the cover plate that closes the assembly port not only restrains the wire harness within the connection port, ensuring a stable connection between the wire harness and the radar, but also isolates the space where the radar is located from the inner space, thus protecting the radar.

[0017] In some embodiments of this application, the bumper body is recessed inward to form a mounting groove for mounting radar;

[0018] The side plate on one side of the mounting slot is set as the wiring part, and the wiring port is set on the wiring part;

[0019] One end of the cover plate is connected to the end of the assembly port away from the wiring part; the other end of the cover plate is attached to the inner surface of the wiring part and snapped into place therewith.

[0020] In the technical solution, the structural design forms an inward recessed mounting groove, which can be integrally machined with the bumper body. This not only provides a dedicated installation space for the radar, avoiding radar damage and reducing space occupation, but also facilitates processing and manufacturing. On the other hand, the cover plate is snapped onto the side plate of the mounting groove, ensuring that the cover plate can close the end of the wiring port connecting to the assembly port, ensuring the constraint of the wiring harness, and facilitating the disassembly of the cover plate.

[0021] In some embodiments of this application, an arc-shaped transition portion is provided at one end of the cover plate connecting to the assembly port.

[0022] In the technical solution, the structural design improves the flexibility of the cover plate connection and makes the cover plate elastic, preventing the connection between the cover plate and the assembly port from breaking when the cover plate is snapped together, and the elastic force generated makes the snapping more tight and firm.

[0023] In some embodiments of this application, the end of the cover plate near the wiring portion is bent outward to form the snap-fit ​​portion; the snap-fit ​​portion is attached to the inner surface of the wiring portion and snap-fitted with it; a limiting opening is provided on the snap-fit ​​portion, the limiting opening extends to the end of the cover plate near the wiring portion, so as to allow the wire harness to enter the limiting opening in a direction parallel to the surface of the snap-fit ​​portion; the snap-fit ​​portions on both sides of the limiting opening are snap-fitted with the wiring portion.

[0024] In the technical solution, the structural design provides a channel for the wire harness to enter the end of the cover plate, eliminating the obstruction of the wire harness to the cover plate and ensuring a tight connection of the cover plate; on the other hand, it makes the cover plate more evenly and firmly connected to both sides of the wire harness, improving the stability and reliability of the connection.

[0025] In some embodiments of this application, the snap-fit ​​part has a snap-fit ​​interface; the inner surface of the wiring part is provided with a snap-fit ​​buckle, which snaps into the snap-fit ​​interface so that the cover plate is snap-fitted and connected to the wiring part.

[0026] In the technical solution, the structural design makes the snap-fit ​​connection of the cover plate tighter and more secure, improving the stability and reliability of the structure. It also facilitates quick disassembly and assembly by operators, improving the efficiency of assembly and maintenance.

[0027] In some embodiments of this application, the bumper body forms a limiting seat by protruding outward; a limiting hole is provided on the side of the limiting seat near the fixed seat, and the limiting hole is used to insert a limiting member.

[0028] In this technical solution, the structural design uses an outward protrusion to form a limiting seat, which can be integrally machined with the bumper body. This not only provides a connection point for radar installation but also serves as a reinforcing structure to enhance the structural strength of the bumper body, thereby improving its resistance to external impacts. Simultaneously, it provides a stable and reliable support point for radar installation, ensuring its stability. Furthermore, the hollow structure of the limiting seat allows for easy insertion with limiting components through openings, enabling rapid and accurate radar positioning and installation, improving assembly efficiency and precision, and facilitating subsequent disassembly and replacement.

[0029] In some embodiments of this application, the bumper body forms a fixing seat by protruding outward; a spring nut is provided on the fixing seat, and the spring nut is threadedly connected to the fixing bolt;

[0030] A mounting hole is made on one side of the fixing seat; one side of the spring nut is attached to the outer top surface of the fixing seat; the other side of the spring nut passes through the mounting hole and is attached to the inner surface of the fixing seat.

[0031] In this technical solution, the structural design features an outward-protruding mounting base, which is integrally machined with the bumper body. This base not only provides a connection point for radar installation but also serves as a reinforcing structure, enhancing the bumper's structural strength and thus improving its resistance to external impacts. Simultaneously, it provides a stable and reliable support point for radar installation, ensuring its stability. Furthermore, the hollow structure of the mounting base allows for the installation of a spring nut through pre-drilled holes, facilitating threaded connection of the fixing bolts and improving assembly convenience. Additionally, the design of the mounting holes and the installation method of the spring nut ensure that it is stably fixed to the mounting base, guaranteeing proper fit with the fixing bolts without affecting the overall structural strength of the mounting base. This also facilitates the installation and replacement of the spring nut.

[0032] In some embodiments of this application, it further includes:

[0033] A limiting protrusion is provided on the bumper body and located between the limiting seat and the fixing seat; the limiting protrusion is used to insert into the limiting groove opened by the radar.

[0034] In this technical solution, the structural design constrains the radar in multiple directions, further enhancing the radar's installation stability, preventing the radar from shaking or shifting during use, improving the stability of the radar during operation, and thus ensuring the accuracy of the radar monitoring data.

[0035] In some embodiments of this application, it further includes:

[0036] The decorative panel is installed on the bumper body; the decorative panel covers the limit seat, the fixing seat and the radar.

[0037] In the technical solution, this structural design not only covers components such as the limit seat, fixing seat, and radar, making the bumper look cleaner and more beautiful and improving the overall visual effect of the vehicle, but also provides a certain degree of protection for components such as radar, preventing external objects from directly impacting or damaging the radar and extending the service life of the radar.

[0038] Secondly, this application provides a vehicle, including:

[0039] Body;

[0040] The bumper structure shown above is installed on the vehicle body.

[0041] In this technical solution, the structural design enables the vehicle to possess all the advantages and effects of the aforementioned bumper structure, such as convenient radar removal and installation, reduced development costs, improved assembly efficiency and maintainability, thereby enhancing the vehicle's market competitiveness and user experience.

[0042] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0057] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0058] It's important to note that in the automotive field, a car primarily comprises an engine (or electric motor), chassis, body, and electrical equipment. It mainly consists of a frame, body panels, and interior structural components. Body panels, such as the hood, fenders, doors, and roof, not only give the car a sleek and aesthetically pleasing appearance but also protect the interior space from environmental damage. The bumper, as a key component of the body panels, is installed at the front and rear of the car. It is not only an important part of the vehicle's appearance but also the first line of defense for vehicle safety. In the event of a collision, it effectively cushions the impact, reducing damage to other parts of the vehicle and providing some protection for pedestrians. With the development of automotive technology, bumpers have also integrated the installation of intelligent driver assistance systems such as radar, further enhancing the car's intelligence and driving safety.

[0059] In existing technologies, radar housings typically have multiple outward-protruding structures on their periphery as connection points. Each connection point is fixed to a bracket using self-tapping screws, thus securing the radar to the bracket. The bracket is then fixed to the bumper using multiple self-tapping screws. This method of fixing with self-tapping screws is not only inconvenient to disassemble, but also requires each radar housing and bracket to be manufactured using its own molds. Each mold needs to be developed, increasing costs and extending the research and development cycle. Furthermore, in existing detachable radar mounting structures, a rotating block is provided at one end of the radar cover plate 203. The rotating block has a radially open shaft hole, and a pivot part is provided on the bumper body. When the radar cover plate 203 is positioned in the mounting hole 401 of the bumper body, the pivot part radially enters the rotating block, rotatably connecting one end of the cover plate 203 to the bumper body. The other end of the cover plate 203 is provided with a buckle 2042, which is then snapped into the mounting hole 401. However, when the vehicle is in motion, bumps and vibrations are transmitted to the bumper body, which can easily cause the pivot part to come off the rotating block or the buckle 2042 to come off the mounting hole 401, making it impossible for the radar to be securely mounted on the bumper body. In addition, because the radar cover plate 203 is equipped with a rotating block and a buckle 2042, the radar's outer shell structure still requires corresponding molds, necessitating mold development, which will increase costs and extend the research and development cycle.

[0060] Based on this, this application proposes a bumper structure with a novel design for a radar mounting structure within the bumper body. This design enables the detachable installation of existing radars with a secure fit, requiring only a separate design for the bumper body structure. This addresses the issues of insufficient installation stability and high development costs associated with existing detachable radar mounting structures on bumpers.

[0061] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0062] See Figures 1 to 9 In one illustrative embodiment of the bumper structure of this application, the bumper structure includes a bumper body 200. The bumper body 200 is the core foundation of the bumper and is typically made of plastic, composite materials, or metal. It is fixed to the front and rear ends of the vehicle body by bolts or clips 2042, etc. The bumper body 200 generally has an overall outward convex structure.

[0063] See Figures 2 to 9 In some embodiments, the bumper structure further includes a limiting seat 300 disposed on the bumper body 200. The limiting seat 300 is a component for mounting and fixing the radar 100, and is typically disposed on the surface of the bumper body 200, so that the radar 100 is mounted and fixed to the surface of the bumper body 200.

[0064] See Figures 2 to 9 In some embodiments, the bumper structure further includes a mounting base 400 and a limiting base 300 disposed on the bumper body 200. The mounting base 400 is a component for mounting and fixing the radar 100 and is typically disposed on the surface of the bumper body 200, so that the radar 100 is mounted and fixed to the surface of the bumper body 200. The mounting base 400 and the limiting base 300 are spaced apart, thereby forming an installation space between them to accommodate the radar 100, so that the mounting base 400 and the limiting base 300 respectively fix the two sides of the radar 100, thus mounting and fixing the radar 100 in the installation space.

[0065] See Figures 2 to 5In some embodiments, a limiting member 101 is provided on one side of the radar 100, and a fixing member 102 is provided on the other side of the radar 100. The limiting member 101 is plugged into the limiting seat 300, and the fixing member 102 is connected to the fixing seat 400 by fixing bolts 103. When installing the fixed radar 100, the inner surface of the radar 100 is usually attached to the outer surface of the bumper body 200, so that both the limiting member 101 and the fixing member 102 are set on the side of the radar 100. Both the limiting member 101 and the fixing member 102 extend in a direction parallel to the outer surface of the bumper body 200. The limiting member 101 is inserted into the slot provided on the side of the limiting seat 300, thereby preventing the radar 100 on one side of the limiting member 101 from moving away from the bumper body 200. The fixing member 102 on the other side is bolted to the fixing seat 400, which not only prevents the radar 100 on the fixing member 102 from moving away from the bumper body 200, but also restricts the radar 100 from moving in a direction parallel to the outer surface of the bumper body 200, so that the limiting member 101 is stably inserted into the limiting seat 300. Because the limiting member 101 is stably inserted into the limiting seat 300, and the fixing member 102 is stably fixed to the fixing seat 400, the radar 100 is stably installed and fixed in the installation space. When it is necessary to disassemble the radar 100, simply remove the fixing bolt 103, which not only disconnects the connection between the fixing member 102 and the fixing seat 400, but also removes the constraint on the limiting member 101, allowing the limiting member 101 to be pulled out from the limiting seat 300, completely eliminating the constraint on the radar 100, and allowing the radar 100 to be removed.

[0066] This structural design achieves stable installation of the radar 100 by inserting the limiting member 101 on one side into the limiting seat 300 and bolting the fixing member 102 on the other side into the fixing seat 400. This also facilitates disassembly and maintenance without requiring the entire bumper to be removed, improving the convenience and efficiency of maintenance. Furthermore, the protruding structure on the outer periphery of the original radar housing, used for mounting self-tapping screws, can serve as the limiting member 101 and the fixing member 102, allowing the bumper device to be used for the installation and fixation of the existing radar. This not only meets the requirements of stable installation and easy disassembly, but also allows for the continued use of existing molds for manufacturing the radar, reducing mold costs and development cycles, thus benefiting cost control and market competitiveness. More specifically, both existing technologies and this application require mold manufacturing for the bumper body 200, while this application does not require mold manufacturing for the radar 100 or the bracket. This results in fewer molds required compared to existing technologies, lower mold costs, and a shorter development cycle.

[0067] See Figures 3 to 9In some embodiments, the bumper body 200 has an assembly port 201 and a wiring port 202. The width of the wiring port 202 is smaller than that of the assembly port 201, and one end of the wiring port 202 extends and connects to the assembly port 201.

[0068] In order to electrically connect the radar 100 to the vehicle's electrical equipment, the wiring harness 500 inside the bumper body 200 needs to pass through the bumper body 200 and connect to the radar 100 on the outside. The wiring harness 500 passes through the inner space of the bumper body 200 via the connector 202 and connects to the radar 100 on the outside.

[0069] The wiring harness 500 typically has a plug 600 at one end, which facilitates connection between the wiring harness 500 and the radar 100 through a plug-in connection with a socket on the radar 100. This connection is detachable. Since the outer diameter of the plug 600 is usually larger than the outer diameter of the wiring harness 500 itself, and the width of the connection port 202 is usually approximately the same as the outer diameter of the wiring harness 500, the plug 600 cannot pass through the connection port 202. One end of the connection port 202 extends outward and connects to the mounting port 201, allowing the plug 600 to pass through the mounting port 201 and then through the bumper body 200. The wiring harness 500 then enters the mounting port 201 along with the plug 600, and from the mounting port 201, it enters the connection port 202.

[0070] One end of the assembly port 201 is integrally connected to a cover plate 203, and the other end of the assembly port 201 is snapped into connection with the cover plate 203, so that the cover plate 203 closes the assembly port 201. Furthermore, the closure of the assembly port 201 prevents the plug 600 from passing through the bumper body 200, thereby restricting the plug 600 to the outer space of the bumper body 200. At the same time, since one end of the wiring port 202 extends to the assembly port 201, the cover plate 203 closes the end of the wiring port 202 that connects to the assembly port 201, thus restricting the wire harness 500 within the wiring port 202.

[0071] This structural design, by opening an assembly port 201 and connecting the wiring port 202 to the assembly port 201, facilitates the passage of the plug 600 and the insertion of the wiring harness 500, improving the ease of installation of the wiring harness 500. Secondly, the cover plate 203, by closing the assembly port 201, confines the wiring harness 500 within the wiring port 202 and simultaneously confines the plug 600 to the outside of the bumper body 200, maintaining the stability of the wiring harness 500 and thus ensuring a stable connection between the wiring harness 500 and the radar 100. Furthermore, the closure of the cover plate 203 separates the space where the radar 100 is located from the inner space of the bumper body 200, preventing the entry of debris and protecting the radar 100. In addition, the cover plate 203 is integrally connected to the mounting opening 201 at one end, so that the cover plate 203 can be formed by bending a part of the bumper body 200 inward. At the same time, since the cover plate 203 is separated from the bumper body 200, the mounting opening 201 is formed on the bumper body 200, so that the cover plate 203 and the mounting opening 201 can be integrally processed with the bumper body 200, which is convenient for processing and manufacturing.

[0072] See Figures 2 to 9 In some embodiments, the bumper body 200 is recessed inward to form a mounting groove 204, in which the radar 100 is mounted and fixed, thereby preventing the radar 100 from protruding outward. The limiting seat 300 and the fixing seat 400 are usually disposed in the mounting groove 204 to mount and fix the radar 100 in the mounting groove 204.

[0073] Mounting slot 204 typically includes a base plate and a side plate located around the base plate. One side plate of mounting slot 204 is designated as a wiring portion 2041, and a wiring port 202 is located in the wiring portion 2041. The wiring port 202 extends through the wiring portion 2041 in a direction parallel to the base plate of mounting slot 204, allowing the wiring harness 500 inside the vehicle body 200 to pass through the wiring portion 2041 of mounting slot 204 via the wiring port 202, and then extend into the mounting slot 204 outside the bumper body 200, connecting with the radar 100. This enables the radar 100 to be electrically connected to the vehicle's electrical equipment, realizing the monitoring function of the radar 100.

[0074] One end of the cover plate 203 is integrally connected to the end of the assembly port 201 away from the wiring part 2041, and the other end of the cover plate 203 is attached to the inner surface of the wiring part 2041 and snapped together, so that the cover plate 203 closes the assembly port 201.

[0075] This structural design allows the mounting groove 204 to be formed by a recess in the bumper body 200, enabling it to be integrally machined with the bumper body 200, facilitating manufacturing. Furthermore, the mounting groove 204 provides dedicated mounting space for the radar 100, preventing damage from outward protrusion and reducing the space occupied by the radar 100. The connection port provides a channel for the wiring harness 500 to pass through the bumper body 200 from the inside out and connect to the radar 100. With the radar 100 concealed within the mounting groove 204, electrical connection between the radar 100 and the vehicle's electrical equipment is achieved. (The last sentence appears to be incomplete and possibly refers to a specific feature or design.) The cover plate 203 is snapped onto the side plate of the mounting groove 204, ensuring that the cover plate 203 can close one end of the wiring port 202 connecting to the assembly port 201, thus ensuring the constraint of the wiring harness 500. Moreover, one end of the cover plate 203 is exposed on the inner surface of the bumper body 200, making it easy to operate the cover plate 203 to eliminate its snap-fit ​​with the wiring part 2041, and making it easy to open the assembly port 201 with the cover plate 203 to remove the wiring harness 500.

[0076] See Figure 3 , Figure 5 , Figures 7 to 9 In some embodiments, one end of the cover plate 203 near the wiring portion 2041 is bent outward to form a snap-fit ​​portion 2031. The snap-fit ​​portion 2031 is attached to the inner surface of the wiring portion 2041, thereby snapping the cover plate 203 one end into the wiring portion 2041. A limiting opening 2032 is provided on the snap-fit ​​portion 2031, which extends to the end of the cover plate 203 near the wiring portion 2041, allowing the cover plate 203 to move outward to close the assembly opening 201. When the snap-fit ​​portion 2031 is attached to the inner surface of the wiring portion 2041, the wire harness 500 in the wiring opening 202 can enter the limiting opening 2032 in a direction parallel to the surface of the snap-fit ​​portion 2031. The snap-fit ​​portion 2031 can extend to both sides of the wiring opening 202. The locking parts 2031 on both sides of the limiting port 2032 are locked and connected to the wiring part 2041, so that both sides of the locking part 2031 are locked and connected to the wiring part 2041 on both sides of the wiring port 202.

[0077] When the cover plate 203 closes the assembly opening 201, this structural design eliminates the obstruction of the wire harness 500 to the further outward movement of the snap-fit ​​part 2031, so that the snap-fit ​​part 2031 and the wiring part 2041 fully overlap. The snap-fit ​​parts 2031 and wiring parts 2041 on both sides of the wire harness 500 are evenly and firmly snapped together, which improves the tightness of the snap-fit ​​connection of the cover plate 203 and enhances the stability and reliability of the connection of the cover plate 203.

[0078] See Figure 5 , Figure 7 and Figure 9In some embodiments, the snap-fit ​​portion 2031 has a snap-fit ​​interface 2033 through which the snap-fit ​​portion 2031 passes. A snap fastener 2042 is provided on the inner surface of the wiring portion 2041. When the snap-fit ​​portion 2031 is attached to the inner surface of the wiring portion 2041, the snap fastener 2042 snaps into the snap fastener interface 2033. The snap fastener 2042 prevents the snap-fit ​​portion 2031 from moving inward away from the wiring portion 2041, so that the cover plate 203 is snap-fitted to the wiring portion, and the cover plate 203 keeps the assembly port 201 and the wiring port 202 closed.

[0079] This structural design makes the snap-fit ​​connection of the cover plate 203 tighter and more secure, and the through-type snap-fit ​​interface 2033 allows the operator to push the buckle 2042 outward, so that the buckle 2042 disengages from the snap-fit ​​interface 2033, eliminating the snap-fit ​​and achieving quick and convenient disassembly.

[0080] Furthermore, when a limiting port 2032 is provided on the snap-fit ​​part 2031, a snap fastener 2042 is provided on both sides of the wiring port 202, and the limiting port 2032 is provided on both sides with a snap-fit ​​interface 2033, thereby realizing that both sides of the snap-fit ​​part 2031 are simultaneously snap-fit ​​connected to the wiring parts 2041 on both sides of the wiring port 202.

[0081] See Figure 9 In some embodiments, an arc-shaped transition portion 2034 is provided at one end of the cover plate 203 that connects to the assembly port 201. This structural design allows the cover plate 203 to flexibly connect to the bottom plate of the mounting groove 204 via the transition portion 2034. The transition portion 2034 can increase or decrease its curvature as the cover plate 203 swings, avoiding a rigid connection between the cover plate 203 and the bottom plate of the mounting groove 204, and preventing cracking at the connection point when the cover plate 203 swings. Furthermore, the transition portion 2034 is elastic, generating a spring force when the cover plate 203 closes the assembly port 201. This spring force allows for a tighter contact between the inner wall of the snap-fit ​​interface 2033 and the snap-fit ​​2042, thereby improving the secureness of the snap-fit ​​connection.

[0082] See Figures 2 to 9 In some embodiments, the limiting seat 300 is located below the fixing seat 400. This structural design allows the limiting member 101 to be inserted into the limiting seat 300 from top to bottom. The gravity of the radar 100 can also prevent the limiting member 101 from being pulled upward out of the limiting seat 300, thereby improving the stability of the insertion connection between the limiting member 101 and the limiting seat 300, and thus improving the stability of the radar 100 installation and fixing, and better resisting the bumps and vibrations during vehicle operation.

[0083] See Figures 2 to 9In some embodiments, the bumper body 200 forms a limiting seat 300 by protruding outward. A limiting hole 301 is provided on the side of the limiting seat 300 near the fixed seat 400, and the limiting member 101 is inserted into the limiting hole 301, thereby realizing the insertion connection between the limiting member 101 and the limiting seat 300.

[0084] This structural design features an outwardly protruding limiting seat 300, allowing it to be integrally machined with the bumper body 200. This not only facilitates manufacturing but also reduces the overall material and weight of the bumper assembly by creating a hollow structure, thus lowering manufacturing costs. Furthermore, the protruding limiting seat 300 acts as a reinforcing rib, enhancing the structural strength of the bumper body 200 and improving its resistance to external impacts. The high-strength bumper body 200 provides stable support for the limiting seat 300 and the fixing seat 400, ensuring a stable and reliable support point for the radar 100 installation and guaranteeing its stability. Additionally, the hollow limiting seat 300 structure allows for easy insertion into the limiting component 101 via openings, enabling quick and accurate positioning and installation of the radar 100, improving assembly efficiency and precision, and facilitating subsequent disassembly and replacement.

[0085] See Figures 2 to 9 In some embodiments, the bumper body 200 forms a mounting base 400 by protruding outwards. The mounting base 400 is provided with a spring nut 700. The spring nut 700 typically includes a resilient spring, which is divided into two stacked parts by bending. The first part of the spring has a nut or a threaded hole for threaded connection with the fixing bolt 103; the second part of the spring has a through hole for the fixing bolt 103 to pass through, thereby threadedly connecting with the first part of the spring.

[0086] A mounting hole 401 is provided on one side of the fixing base 400. One side of the spring nut 700 is attached to the outer top surface of the fixing base 400, so that the first part of the spring nut 700 is attached to the outer top surface of the fixing base 400. The other side of the spring nut 700 passes through the mounting hole 401 and is attached to the inner surface of the fixing base 400, so that the first part of the spring nut 700 extends into the fixing base 400 and is attached to the inner top surface of the fixing base 400. The spring nut 700 is fixed to the top plate of the fixing base 400 by its elastic clamping. The fixing bolt 103 on the fixing member 102 passes through the second part of the spring nut 700, the opening in the top plate of the fixing base 400, and the first part of the spring nut 700 from the outside to the inside, and is threadedly connected to the spring nut 700, thereby realizing the bolted connection between the fixing base 400 and the fixing member 102.

[0087] The structure is designed with an outward protrusion forming a fixing seat 400, allowing the fixing seat 400 to be integrally machined with the bumper body 200. This not only facilitates manufacturing but also makes the fixing seat 400 hollow, reducing the overall material usage and weight of the bumper assembly and lowering manufacturing costs. Secondly, the protruding fixing seat 400 acts as a reinforcing rib, increasing the structural strength of the bumper body 200 and improving its resistance to external impacts. The high-strength bumper body 200 provides stable reverse support for the limiting seat 300 and the fixing seat 400, ensuring a stable and reliable support point for the installation of the radar 100 and guaranteeing the stability of the radar 100 installation. Furthermore, the hollow fixing seat 400 allows for the installation of the spring nut 700 through openings, facilitating the threaded connection of the fixing bolt 103 and improving assembly convenience. In addition, the spring nut 700 extends into the fixing seat 400 through the mounting hole 401 and clamps the top plate of the fixing seat 400, so that the spring nut 700 can be stably fixed on the fixing seat 400. This ensures that it is properly matched with the fixing bolt 103, does not affect the overall structural strength of the fixing seat 400, and is also conducive to the installation and replacement of the spring nut 700.

[0088] See Figures 8 to 9 In some embodiments, the bumper structure further includes a limiting protrusion 205. The limiting protrusion 205 is disposed on the bumper body 200, protruding outward relative to the outer surface of the bumper body 200. The limiting protrusion 205 is located between the limiting seat 300 and the fixing seat 400, such that the limiting protrusion 205 is positioned opposite to the radar 100. A limiting groove is formed on the inner surface of the radar 100, and the limiting protrusion 205 is inserted into the limiting groove. Through the insertion of the limiting member 101 and the limiting seat 300, the limiting seat 300 prevents the radar 100 on one side of the limiting member 101 from moving outward away from the bumper body 200, thus achieving limitation of the radar 100 in the Z direction. Through the insertion of the limiting protrusion 205 and the limiting groove, the limiting protrusion 205 prevents the radar 100 from moving in a direction parallel to the surface of the bumper body 200, thus achieving limitation of the radar 100 in the X direction, which is typically perpendicular to the Z direction.

[0089] Furthermore, the limiting protrusion 205 is typically elongated and perpendicular to the line connecting the fixing seat 400 and the limiting seat 300, so that the limiting protrusion 205 can better limit the radar 100 in the X direction, ensuring that the limiting member 101 on one side of the radar 100 is stably inserted into the limiting seat 300.

[0090] This structural design allows the plug-in connection of the radar 100 to constrain the radar 100 in two mutually perpendicular directions. In addition, the bolt connection on one side of the radar 100 further enhances the installation stability of the radar 100, preventing the radar 100 from shaking or shifting during use, improving the stability of the radar 100 during operation, and thus ensuring the accuracy of the radar 100 monitoring data.

[0091] See Figure 1 In some embodiments, the bumper structure further includes a decorative panel 800. The decorative panel 800 is disposed on the bumper body 200, such that it partially or completely covers the outer surface of the bumper body 200, and simultaneously covers the limiting seat 300, the fixing seat 400, and the radar 100. This structural design allows the decorative cover to not only conceal components such as the limiting seat 300, the fixing seat 400, and the radar 100, making the bumper appearance cleaner and more aesthetically pleasing, and improving the overall visual effect of the vehicle, but also to provide a certain degree of protection for components such as the radar 100, preventing external objects from directly impacting or damaging the radar 100, and extending the service life of the radar 100.

[0092] Furthermore, this application also provides a vehicle comprising a body. The body is the core structure of the vehicle, including a chassis and body panels. The chassis provides basic support and driving functions for the vehicle, while the body panels constitute the vehicle's appearance and protect internal components. The vehicle further includes the aforementioned bumper structure, which is mounted on the vehicle body and typically serves as part of the body panels. This design allows the vehicle to possess all the advantages and effects of the aforementioned bumper structure, such as convenient radar 100 removal and installation, reduced development costs, improved assembly efficiency and maintainability, thereby enhancing the vehicle's market competitiveness and user experience.
