Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle body assembly and a vehicle. Background Technology

[0002] In automobile manufacturing, the rear bumper (referred to as the rear bumper) is an important component of the vehicle's external structure. Its assembly precision directly affects the quality of the gap and surface difference matching of the entire vehicle's appearance, especially the uniformity of the gaps and the surface flatness between the rear bumper and adjacent components such as the side sheet metal, taillights, and tailgate.

[0003] In related technologies, the rear bumper is usually assembled to the vehicle body through a rear bumper side bracket and a rear bumper side-rear bracket. During the assembly process, the rear bumper side-rear bracket uses two locating pins to engage with two locating holes on the side panel sheet metal from one side of the vehicle body in the width direction. The two locating pins are arranged at intervals along the front-rear direction of the vehicle body and extend along the width direction of the vehicle body. The rear bumper side bracket is set on the front side of the rear bumper side-rear bracket and is fixedly connected to the vehicle body. The rear bumper is initially positioned by relying on the rear bumper side-rear bracket and the rear bumper side bracket, and then the rear bumper is fixed to the vehicle body by snap-fitting, bolt tightening and other methods, thereby realizing the installation of the rear bumper on the vehicle body.

[0004] However, in the relevant technology, the small distance between the two positioning pins in the rear side bracket of the rear bumper in the front-rear direction of the vehicle body causes the rear end of the rear side bracket to form a cantilever structure, which leads to the unstable positioning of the rear side bracket. This results in the excessive surface gap difference around the rear bumper after installation, affecting the overall appearance quality of the vehicle. Utility Model Content

[0005] In view of the above problems, this application provides a vehicle body assembly and vehicle to improve the positioning stability of the rear bumper side rear bracket, thereby improving the surface gap difference around the rear bumper after installation and improving the overall vehicle appearance quality.

A bolt is provided on the vehicle body at the position corresponding to the first through hole, and a first threaded hole is provided on the vehicle body at the position corresponding to the second through hole.

[0022] The bolt passes through the first through hole and is sealed and threadedly connected to the second fastening nut. The first threaded fastener passes through the second through hole and is sealed and threadedly connected to the first threaded hole.

[0023] In some embodiments, the vehicle assembly further includes two second threaded fasteners;

[0024] The rear side bracket has two third through holes spaced apart along the front-rear direction of the vehicle body.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] In automobile manufacturing, the rear bumper (referred to as the rear bumper) is an important component of the vehicle's external structure. Its assembly precision directly affects the quality of the gap and surface difference matching of the entire vehicle's appearance. In particular, it has a significant impact on the uniformity of the gaps and the surface flatness of the rear bumper and adjacent components such as the side sheet metal, taillights, and tailgate of the vehicle body.

[0054] The rear bumper is typically assembled to the vehicle body via a rear bumper side bracket and a rear bumper side-rear bracket. During assembly, the rear bumper side-rear bracket uses two locating pins on one side of the vehicle body in the width direction to engage with two locating holes on the side panel. The two locating pins are spaced apart along the front-rear direction of the vehicle body and extend along the width direction of the vehicle body. The rear bumper side bracket is located on the front side of the rear bumper side-rear bracket and is fixedly connected to the vehicle body. The rear bumper is initially positioned by relying on the rear bumper side-rear bracket and the rear bumper side bracket, and then the rear bumper is fixed to the vehicle body by snap-fitting, bolt tightening, etc., thus realizing the installation of the rear bumper on the vehicle body.

[0055] It should be noted that in the embodiments of this application, the front-to-back direction of the vehicle body is consistent with the front-to-back direction of the vehicle, for example, represented by the X direction; the width direction of the vehicle body is, for example, when standing at the rear of the vehicle body, the left-to-right direction of the vehicle body, for example, represented by the Y direction; and the height direction of the vehicle body (i.e., the vertical direction) is represented by the Z direction.

[0056] However, since the rear bumper side bracket is positioned and installed on the vehicle body in the Y direction, and the distance between the two positioning pins in the rear bumper side bracket in the front-rear direction (X direction) of the vehicle body is small, the rear end of the rear bumper side bracket forms a cantilever structure, which causes the rear bumper side bracket to become unstable in positioning. This leads to excessive surface gap difference around the rear bumper after installation, affecting the overall appearance quality of the vehicle.

[0057] To overcome the deficiencies in the prior art, this application provides a vehicle body assembly that increases the distance between the two positioning structures used to position the rear bumper side support by positioning it along the X direction of the vehicle body. During positioning, the structure is positioned with both the rear bumper side support and the vehicle body, thereby increasing the mounting point at the rear end of the rear bumper side support. This improves the positioning stability of the rear bumper side support, eliminates the cantilever effect at the rear end of the rear bumper side support, and improves the surface gap and surface difference around the rear bumper after installation, thus enhancing the overall appearance quality of the vehicle.

[0058] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0059] Please refer to Figure 1 and Figure 2As shown, this application embodiment provides a vehicle body assembly 10, which includes a vehicle body 100 and two rear bumper 400 mounting components. The two rear bumper 400 mounting components are symmetrically arranged on opposite sides of the vehicle body 100 along the width direction and are located near the rear end of the vehicle body 100. Each rear bumper 400 mounting component includes a rear bumper side bracket 200 and a rear bumper side rear bracket 300. The rear bumper side bracket 200 is located on one side of the vehicle body 100 in the width direction and is fixedly connected to the vehicle body 100 by means of snap-fit, threaded connection, etc. The rear bumper side bracket 200 is located near the rear end of the vehicle body 100 and extends along the front-rear direction (i.e., the X direction) of the vehicle body 100. The bracket 300 is disposed at the rear end of the rear bumper side bracket 200. The rear bumper side bracket 300 has a first positioning structure 310 and a second positioning structure 320 spaced apart along the width direction of the vehicle body 100. Both the first positioning structure 310 and the second positioning structure 320 extend along the front-rear direction of the vehicle body 100. The vehicle body 100 has a first positioning part 210 that matches the first positioning structure 310. The rear bumper side bracket 200 has a second positioning part that matches the second positioning structure 320. The first positioning structure 310 is configured to be mutually positioned and sealed with the first positioning part 210. The second positioning structure 320 is configured to be mutually positioned and sealed with the second positioning part.

[0060] like Figure 3 and Figure 4 As shown, the first positioning structure 310 is a first positioning hole, and the first positioning part 210 is a positioning post extending along the front-rear direction of the vehicle body 100. The first positioning hole and the positioning post cooperate in the X direction to form the main positioning of the rear side bracket 300. The second positioning structure 320 is a positioning pin, and the second positioning part is a second positioning hole. That is, the positioning post and the first positioning hole are mutually positioned and cooperated in the X direction to form the secondary positioning of the rear side bracket 300. The positioning pin is located at the front end of the first positioning hole.

[0061] In addition, the second positioning hole can be an oblong hole, which can compensate for the error between the positioning post and the positioning pin, thereby avoiding the problem that the positioning pin cannot be inserted into the second positioning hole.

[0062] For example, the positioning post is a columnar structure with a circular cross-section, and the positioning pin can also be a columnar structure with a circular cross-section. Correspondingly, the first positioning hole is a circular hole that matches the cross-sectional profile of the positioning post, and the second positioning hole is a circular hole that matches the cross-sectional profile of the positioning pin.

[0063] In addition, in order to improve the strength of the body 100 and the sealing between the positioning post and the body 100, the positioning post can be welded to the body 100 to form an integral structure, thereby improving the reliability of the connection between the positioning post and the body 100, while also improving the structural strength and waterproof performance of the body 100.

[0064] During the specific installation and positioning, the rear side bracket 300 is installed from back to front along the X direction of the vehicle body 100, so that the positioning post is aligned with the first positioning hole and the positioning pin is aligned with the second positioning hole. In this way, the positioning post and the positioning pin together provide a positioning pre-attachment point for the rear side bracket 300 and position the rear side bracket 300 in the Z, Y and X directions. Then, the rear side bracket 300 is fixed to the rear side bracket 200 and the vehicle body 100 respectively by means of snap-fit, threaded connection, etc., thereby realizing the positioning and fixing of the rear side bracket 300.

[0065] When installing the rear bumper side bracket 300, it is installed from the rear end of the vehicle body 100 forward and positioned along the X direction. The second positioning structure 320 of the two positioning points is associated with the rear bumper side bracket 200, and the first positioning structure 310 is associated with the vehicle body 100. This increases the distance between the first positioning structure 310 and the second positioning structure 320, which can effectively eliminate the cantilever effect formed at the rear end of the rear bumper side bracket 300, thereby improving the positioning stability of the rear bumper side bracket 300, reducing assembly errors, and further improving the surface gap and surface difference around the rear bumper 400 after installation, thus improving the overall appearance quality of the vehicle.

[0066] To improve the positioning reliability of the locating pin, please refer to... Figure 3 As shown, multiple reinforcing ribs 330 are provided at the connection between the positioning pin and the rear bumper side bracket 300. The multiple reinforcing ribs 330 are spaced apart along the outer peripheral wall of the positioning pin to prevent the positioning pin from deforming, thereby improving the connection reliability between the positioning pin and the rear bumper side bracket 300, and thus improving the positioning reliability of the positioning pin.

[0067] For example, the cross-sectional shape of the reinforcing rib 330 along the axis parallel to the locating pin includes, but is not limited to, a triangle. For example, the reinforcing rib 330 is a triangular rib plate, as long as it can improve the structural strength of the locating pin root, and no specific limitation is made here.

[0068] Please refer to Figure 4 and Figure 5 As shown, the vehicle body assembly 10 also includes a first fastening nut 510. When the first positioning structure 310 is a first positioning hole and the first positioning part 210 is a positioning post, the outer peripheral wall of the positioning post has an external thread that matches the first fastening nut 510. The first fastening nut 510 is configured to be threadedly connected to the external thread.

[0069] In other words, during installation, the positioning pin passes through the first positioning hole on the rear bumper side rear bracket 300, and the first fastening thread is threadedly connected to the positioning pin at the rear end of the rear bumper side rear bracket 300, thereby fixing the rear bumper side rear bracket 300 in the X direction. It can be seen that while the positioning pin positions the rear bumper side rear bracket 300 in the Z, Y, and X directions, it also fixes the rear bumper side rear bracket 300 in the X direction.

[0070] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the vehicle body assembly 10 also includes a second fastening nut 520 and a first threaded fastener 710; the rear bumper side rear bracket 300 has a first through hole 340 and a second through hole 350 extending along the front-rear direction of the vehicle body 100. The first through hole 340 is located below the first positioning structure 310, and the second through hole 350 is located between the first positioning structure 310 and the second positioning structure 320. A bolt 220 is provided at a position on the vehicle body 100 corresponding to the first through hole 340, and a first threaded hole is provided at a position on the vehicle body 100 corresponding to the second through hole 350; the bolt 220 passes through the first through hole 340 and seals and is threadedly connected to the second fastening nut 520, and the first threaded fastener 710 passes through the second through hole 350 and seals and is threadedly connected to the first threaded hole.

[0071] Among them, bolt 220 includes, but is not limited to, welding to the body 100. When bolt 220 is welded to the body 100, the connection reliability between bolt 220 and body 100 can be improved, and the structural strength and waterproof performance of body 100 can be improved.

[0072] It is understandable that the outer peripheral wall of the bolt 220 has external threads. When the rear bumper side rear bracket 300 is installed from back to front, the bolt 220 passes through the second through hole 350, and the second fastening nut 520 is threadedly connected to the bolt 220 from the rear end of the rear bumper side rear bracket 300. At the same time, the first threaded fastener 710 passes through its corresponding second through hole 350 and is threadedly connected to the first threaded hole on the rear bumper side bracket 200, thereby jointly achieving the fixation of the rear bumper side rear bracket 300 along the X direction.

[0073] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the vehicle body assembly 10 also includes two second threaded fasteners 720; the vehicle body 100 has two third through holes 360 spaced apart along the X direction of the vehicle body 100, each third through hole 360 ​​extending along the Y direction of the vehicle body 100, and the two third through holes 360 are located between the second positioning structure 320 and the second through hole 350; the vehicle body 100 has a second threaded hole at the position corresponding to the two third through holes 360, and the two second threaded fasteners 720 pass through their corresponding third through holes 360 and are threadedly connected to the corresponding second threaded holes.

[0074] In this way, when installing the rear bumper side bracket 300 from back to front, the rear bumper side bracket 300 is first pre-mounted using positioning posts and positioning pins to position it in the Z, Y, and X directions. Then, along the X direction, the first fastening nut 510 is tightened sequentially with the positioning post, fastening bolt 220, and second fastening thread, and the first threaded fastener 710 and its corresponding first threaded hole are tightened. Then, along the Y direction, the two second threaded fasteners 720 and their corresponding second threaded holes are tightened. This achieves the following: the rear bumper side bracket 300 is first assembled and positioned along the X direction, and then the rear bumper side bracket 200 is threadedly tightened along the X and Y directions respectively. This improves the uniformity of positioning and tightening, effectively eliminates the cantilever effect formed at the rear end of the rear bumper side bracket 300, thereby improving the positioning stability of the rear bumper side bracket 300, reducing assembly errors, and improving the surface gap difference around the rear bumper 400 after installation, thus improving the overall vehicle appearance quality.

[0075] In addition, in order to improve the waterproof performance of the vehicle body 100, in some embodiments, the vehicle body assembly 10 also includes a seal 600, which is disposed on the end face of the first positioning hole facing the positioning post and surrounds the outer peripheral wall of the positioning post to seal the gap between the outer peripheral wall of the positioning post and the positioning hole.

[0076] The sealing element 600 includes, but is not limited to, waterproof foam to prevent water from entering through the gap between the first positioning hole and the positioning post, thereby improving the sealing performance of the vehicle body 100.

[0077] In addition, a seal 600 is provided between the thread and the first through hole 340. The seal 600 includes, but is not limited to, waterproof foam to improve the sealing performance when the vehicle body 100 is fastened to the rear side bracket 300.

[0078] In some embodiments, please refer to Figure 4As shown, the vehicle body assembly 10 also includes a first waterproof clip 810 and two second waterproof clips 820. The first waterproof clip 810 is snapped onto the rear bumper side bracket 200 at a position corresponding to the second through hole 350, and the first waterproof clip 810 has a first threaded hole. The two second waterproof clips 820 are snapped onto the vehicle body 100 and are respectively positioned opposite to the two third through holes 360. Each second waterproof clip 820 has a second threaded hole. In this way, it is not necessary to form the first threaded hole and the second threaded hole on the vehicle body 100. The first threaded fastener 710 is sealed to the first waterproof clip 810, and each second threaded fastener 720 is sealed to the corresponding second waterproof clip 820. This prevents the problem of poor sealing when the first threaded fastener 710 and the second threaded fastener 720 are connected to the vehicle body 100, and prevents water leakage into the vehicle body 100, thereby improving the overall sealing reliability of the vehicle body 100.

[0079] This application also provides a vehicle, which includes, but is not limited to, sedans, SUVs, sports cars, trucks, etc. Any vehicle that requires the installation of a bumper is within the scope of protection of this application, and will not be listed here.

[0080] In summary, in the vehicle body assembly and vehicle provided in this application embodiment, when installing the rear bumper side rear bracket, the rear bumper side rear bracket is installed from the rear end of the vehicle body to the front. The rear bumper side rear bracket is provided with a first positioning structure and a second positioning structure. The first positioning structure and the second positioning structure are spaced apart along the width direction of the vehicle body, and both extend along the front-rear direction of the vehicle body. Correspondingly, a first positioning part matching the first positioning structure is provided at a position on the vehicle body corresponding to the first positioning structure, and a second positioning part is provided at a position on the rear bumper side bracket corresponding to the second positioning structure. The first positioning structure and the first positioning part are mutually positioned and sealed together, and the second positioning structure and the second positioning part are mutually positioned and fitted together. Therefore, the first positioning structure and the second positioning structure are positioned from rear to front along the front-rear direction of the vehicle body and are spaced apart along the width direction of the vehicle body, increasing the positioning distance between the first positioning structure and the second positioning structure. This effectively eliminates the cantilever effect formed at the rear end of the rear bumper side rear bracket, thereby improving the positioning stability of the rear bumper side rear bracket, reducing assembly errors, and further improving the surface gap difference around the rear bumper after installation, thus improving the overall vehicle appearance quality.
