Technical Field

[0001] This application belongs to the technical field of vehicles, and particularly relates to a vehicle front-end assembly, a vehicle, and a method for assembling the vehicle front-end assembly. Background Technology

[0002] In the car-buying process, perceived quality has become a crucial factor driving consumer decisions. The perceived quality of the exterior, especially the front fascia, is one of the areas most significantly impacting visual perception. Controlling the gaps and staggered distances between various front-fascia components (including the front combination lights and front bumper) is a vital element of visual perception quality, directly reflecting the manufacturer's precision control and attention to detail. Therefore, controlling the manufacturing precision of the front fascia is extremely important. In related technologies, the positional accuracy and errors of front-fascia components such as the front combination lights and front bumper assembly are often poor after installation. Summary of the Invention

[0003] This application aims to at least partially solve the technical problem of poor positional accuracy after the installation of front-end components such as front combination lights and front bumpers in related technologies.

[0010] The compensation bracket is also provided with a third connecting hole whose axis is parallel to the vehicle height direction, and the connecting bracket is provided with a fourth connecting hole whose axis is parallel to the vehicle height direction; the fourth connecting hole is located within the projection of the third connecting hole toward the connecting bracket, or the third connecting hole is located within the projection of the fourth connecting hole toward the compensation bracket, and the connecting bracket and the compensation bracket are fixedly connected by a second connecting member located within the third connecting hole and the fourth connecting hole.

[0011] In some embodiments, the connecting bracket and the front panel component are movably connected.

[0012] In some embodiments, the connecting bracket is provided with a fifth connecting hole, and the front face part is provided with a sixth connecting hole. The fifth connecting hole is located within the projection of the sixth connecting hole toward the connecting bracket, or the sixth connecting hole is located within the projection of the fifth connecting hole toward the front face part. The connecting bracket and the front face part are fixedly connected by a third connector located in the fifth connecting hole and the sixth connecting hole.

[0013] In some embodiments, the connecting bracket is provided with a first positioning structure, and the front part is provided with a second positioning structure adapted to the first positioning structure, wherein the first positioning structure and the second positioning structure are positioned and engaged.

[0014] In some embodiments, a second positioning part is provided on the front-end module, the second positioning part being used for positioning with the vehicle body.

[0015] In some embodiments, the front-end module includes a front-end frame and a crash beam assembly connected together, and the second positioning part is disposed on the front-end frame; a plurality of compensation brackets are provided, and the plurality of compensation brackets are respectively installed on the front-end frame and the crash beam assembly.

[0016] In some embodiments, a plurality of the compensation brackets are respectively mounted on the end face of the front frame facing the anti-collision beam assembly and the end face of the anti-collision beam assembly facing the connecting bracket, the connecting bracket being located on the compensation bracket.

[0017] Secondly, embodiments of this application provide a vehicle including the vehicle front-end assembly provided in the first aspect above, wherein the vehicle body includes longitudinal beams, and the front-end module of the vehicle front-end assembly is fixedly connected to the longitudinal beams.

[0018] In some embodiments, the vehicle body is provided with positioning holes and positioning surfaces, and the first positioning part of the vehicle front end assembly is positioned and connected to the first positioning hole and the first positioning surface.

[0019] Thirdly, embodiments of this application provide a method for assembling a vehicle front-end assembly. This method is used to assemble the vehicle front-end assembly provided in the first aspect or the vehicle provided in the second aspect, and includes the following steps:

[0020] S100, the front-end module is installed on the vehicle body;

[0021] S200, the first positioning part of the connecting bracket and the vehicle body are positioned and connected by the connecting bracket assembly tooling;

[0022] S300, Adjust the compensation bracket and connect the compensation bracket and the connecting bracket;

[0023] S400, the front panel component is installed onto the connecting bracket.

[0024] The present invention has at least the following beneficial effects:

[0025] The vehicle front-end assembly provided by the present invention includes a front-end module, a compensation bracket, a connecting bracket, and a front-end component. The front-end module is used to connect with the vehicle body. The compensation bracket is movably connected to the front-end module. The connecting bracket is mounted on the front-end module through the compensation bracket. The front-end component is mounted on the connecting bracket, and a first positioning part is provided on the connecting bracket.

[0026] With this design, the connecting bracket can be positioned and connected to the vehicle body under the action of the first positioning part. The vehicle body is used as the installation reference. After the connecting bracket and the vehicle body are accurately positioned, the connecting bracket is accurately fixed on the front module by adjusting the compensation bracket. This allows the connecting bracket to be accurately positioned in three directions: the length, width, and height of the vehicle body, thereby ensuring the positional accuracy of the front-end parts installed on the connecting bracket.

[0027] In other words, with this design, although the connecting bracket is fixed on the front-end module, its installation reference is no longer the front-end module. It will not be affected by the manufacturing errors of the front-end module. It directly uses the vehicle body as the installation reference and is precisely installed through the compensation bracket. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0044] In the process of consumers buying a car, perceived quality has become an important factor driving their purchase decisions. The perceived quality of the exterior, especially the perceived quality of the front end, is one of the areas that most significantly affects customers' visual perception. The control of the gaps and steps between various parts of the front end (including the front combination lights and the front bumper) is an important component of visual perception quality. It can directly reflect the precision control and detail processing capabilities of the car manufacturer. Therefore, the control of the manufacturing precision of the front end is very important.

[0045] Currently, front-end components such as the front combination lights and front bumper assembly are connected and fixed to the front-end module (front frame and anti-collision beam assembly). The front-end module is connected and fixed to the left and right longitudinal beam assemblies of the body-in-white. The longitudinal beam assemblies generally have high strength but poor formability, making it difficult to control dimensional deviations and resulting in large positional errors. Therefore, the position of the front-end module installed on it also has a large error, which ultimately affects the positional accuracy of front-end components such as the front combination lights and front bumper that rely on the front-end module for positioning.

[0046] Therefore, in related technologies, there is a technical problem of poor positional accuracy after the front-end components are installed. This application provides a vehicle front-end assembly, a vehicle, and a method for assembling the vehicle front-end assembly, which can at least partially solve the above-mentioned technical problems.

[0047] This application is described below with reference to the accompanying drawings and specific embodiments:

[0048] like Figure 1 , Figure 2 and Figure 9 As shown, the vehicle front-end assembly 100 of this application includes a front-end module 110, a compensation bracket 140, a connecting bracket 120, and a front face part 130. The compensation bracket 140 is movably connected to the front-end module 110, and the front face part 130 is mounted on the connecting bracket 120. The connecting bracket 120 is provided with a first positioning part 120a, which is used to position the vehicle body 200. Under the condition that the first positioning part 120a is positioned and connected to the vehicle body 200, the position of the compensation bracket 140 relative to the front-end module 110 can be adjusted so that the compensation bracket 140 is fixedly connected to the connecting bracket 120.

[0049] In other words, the front face part 130 of the vehicle front-end assembly 100 of this application is mounted on the connecting bracket 120, the compensation bracket 140 is movably connected to the front-end module 110, the connecting bracket 120 is mounted on the front-end module 110 through the compensation bracket 140, and the front-end module 110 is connected to the body 200. With this design, when installing the connecting bracket 120, the connecting bracket 120 is first positioned and connected to the body 200 through the first positioning part 120a, and then the position of the compensation bracket 140 on the front-end module 110 is adjusted so that the adjusted position of the compensation bracket 140 can be adapted to the positioned connecting bracket 120, so that the compensation bracket 140 can be fixedly connected to the connecting bracket 120.

[0050] When positioning the connecting bracket 120, the connecting bracket assembly fixture 2000 is usually used, such as... Figure 9 and Figure 10As shown, one side of the connecting bracket assembly fixture 2000 is positioned and engaged with the vehicle body 200, and the other side is positioned and engaged with the first positioning part 120a on the connecting bracket 120, thereby indirectly enabling the first positioning part 120a of the connecting bracket 120 to be positioned and connected with the vehicle body 200, thus ensuring the relative positional relationship between the connecting bracket 120 and the vehicle body 200.

[0051] The structure of the first positioning part 120a on the connecting bracket 120 is varied, and can be a positioning hole, positioning groove, positioning protrusion, etc., which are not limited in this application.

[0052] With this design according to the present application, the connecting bracket 120 is not installed with the front module 110 as the reference. Instead, the connecting bracket 120 is installed on the front module 110 with the vehicle body 200 as the reference. It is no longer affected by the manufacturing and installation errors of the front module 110, which allows the connecting bracket 120 to be accurately positioned in the length, width and height directions of the vehicle body 200. This ensures the positional accuracy of the connecting bracket 120, and in turn ensures the positional accuracy of the front face parts 130 installed on it, which helps to improve the perceived quality of the front appearance dimensions of the vehicle 1000.

[0053] In some embodiments, the compensation bracket 140 is movably connected to the front-end module 110 along the length, width, and height directions of the vehicle body 200. That is, after the compensation bracket 140 moves a certain distance along the length, width, or height directions of the vehicle body 200, it can still be connected to the front-end module 110 to match the position of the connecting bracket 120 after positioning. This design simplifies the structure of the connecting bracket 120 and facilitates its processing. To achieve the movable connection of the compensation bracket 140 along the length, width, and height directions of the vehicle body 200 to the front-end module 110, in some embodiments, the compensation bracket 140 includes a first compensation bracket and a second compensation bracket movably connected along the height direction of the vehicle body 200. The second compensation bracket can still be connected to the first compensation bracket after moving a certain distance along the height direction, thus achieving height adjustment of the compensation bracket 140. Multiple mounting holes are arranged in an array on the front-end module 110, and the first compensation bracket can be fixedly connected to the front-end module 110 through any one of these mounting holes, thereby achieving the movable connection of the compensation bracket 140 along the length and width directions of the vehicle body 200.

[0054] In some embodiments, to further simplify the structure of the compensation bracket 140 and the connecting bracket 120 and facilitate their connection, the compensation bracket 140 is only movably connected to the front-end module 110 in the height direction of the vehicle body 200; after the connecting bracket 120 is positioned, it is shifted in the width and length directions of the vehicle body 200. The design of the large and small holes ensures that the compensation bracket 140 and the connecting bracket 120 can still be installed smoothly, as detailed below:

[0055] like Figure 2 As shown, the front-end module 110 is provided with a first connecting hole 110a, and the compensation bracket 140 is provided with a second connecting hole 140a. At least one of the first connecting hole 110a and the second connecting hole 140a is a strip-shaped hole along the height direction of the vehicle body 200. The compensation bracket 140 and the front-end module 110 are movably connected in the height direction of the vehicle body 200 through a first connector located in the first connecting hole 110a and the second connecting hole 140a. For example... Figure 2 As shown, the compensation bracket 140 is also provided with a third connecting hole 140b whose axis is parallel to the height direction of the vehicle body 200, and the connecting bracket 120 is provided with a fourth connecting hole 120b whose axis is parallel to the height direction of the vehicle body 200, as shown. Figure 3 As shown; the fourth connecting hole 120b is located within the projection of the third connecting hole 140b toward the connecting bracket 120, or the third connecting hole 140b is located within the projection of the fourth connecting hole 120b toward the compensation bracket 140. The connecting bracket 120 and the compensation bracket 140 are fixedly connected by second connectors located within the third connecting hole 140b and the fourth connecting hole 120b. At least one of the first connecting hole 110a and the second connecting hole 140a is a strip-shaped hole extending along the height direction of the vehicle body 200, so that after the compensation bracket 140 moves a certain distance along the height direction of the vehicle body 200, the first connecting hole 110a and the second connecting hole 140a can still be passed through by the first connector, so that the compensation bracket 140 can still be fixedly connected to the front-end module 110, realizing the movable connection of the compensation bracket 140 to the front-end module 110 in the height direction of the vehicle body 200. The third connecting hole 140b and the fourth connecting hole 120b are designed such that after the connecting bracket 120 is positioned, the third connecting hole 140b and the fourth connecting hole 120b are misaligned by a certain distance in the length or width direction of the vehicle body 200. The second connecting member can still pass through the third connecting hole 140b and the fourth connecting hole 120b, allowing the connecting bracket 120 to still be fixedly connected to the front-end module 110. With this design, when the front end frame 111 is positioned and connected to the vehicle body 200 and offset by a certain distance in the width or length direction of the vehicle body 200, there is no need to adjust the compensation bracket 140 along the width or length direction of the vehicle body 200. The connecting bracket 120 can still be connected to the compensation bracket 140, facilitating the installation of the front-end assembly 100 of the vehicle in this application.

[0056] In some embodiments, the first connecting hole 110a is a circular hole and the second connecting hole 140a is a strip hole. The diameter of the circular hole and the width of the strip hole are the same. The first connecting member in the first connecting hole 110a and the second connecting hole 140a is a first bolt. When it is necessary to adjust the height of the compensation bracket 140, the first bolt is loosened, and then the compensation bracket 140 is moved to the specified height. Then the bolt is tightened to fix the compensation bracket 140 and the front end module 110. In some embodiments, the third connecting hole 140b and the fourth connecting hole 120b are both circular holes, with the diameter of the fourth connecting hole 120b being larger than the diameter of the third connecting hole 140b. The second connecting element inside the third connecting hole 140b and the fourth connecting hole 120b is a second bolt. When the connecting bracket 120 and the vehicle body 200 are positioned and connected, even if the fourth connecting hole 120b and the third connecting hole 140b on the connecting bracket 120 are misaligned by a certain distance in the length or width direction of the vehicle body 200, the second bolt can still penetrate the third connecting hole 140b and the fourth connecting hole 120b, thereby achieving the fastening of the connecting bracket 120 and the compensation bracket 140.

[0057] In some embodiments, the connecting bracket 120 and the front fascia component 130 are movably connected. That is, even after the front fascia component 130 moves a certain distance along the length, width, or height of the vehicle body 200, it can still be fixedly connected to the connecting bracket 120. With this design, if the installation accuracy of the connecting bracket 120 is not high, which affects the positional accuracy of the front fascia component 130, the relative position of the front fascia component 130 with respect to the connecting bracket 120 can be adjusted to correct the position of the front fascia component 130 relative to the vehicle body 200, thereby ensuring the positional accuracy of the front fascia component 130 relative to the vehicle body 200.

[0058] To achieve a movable connection between the connecting bracket 120 and the front part 130, in some embodiments, such as Figure 7 and Figure 8As shown, the connecting bracket 120 has a fifth connecting hole 120c, and the front part 130 has a sixth connecting hole 130a. The fifth connecting hole 120c is located within the projection of the sixth connecting hole 130a toward the connecting bracket 120, or the sixth connecting hole 130a is located within the projection of the fifth connecting hole 120c toward the front part 130. The connecting bracket 120 and the front part 130 are fixedly connected by a third connector located within the fifth connecting hole 120c and the sixth connecting hole 130a. With this design, even if the front part 130 moves to a certain position, the fifth connecting hole 120c and the sixth connecting hole 130a can still be aligned because the fifth connecting hole 120c and the second connecting hole 140a are different in size, allowing the third connector to pass through and fix the front part 130 and the connecting bracket 120. In some embodiments, the third connector is a third bolt, the fifth connecting hole 120c and the sixth connecting hole 130a are both circular holes, the diameter of the sixth connecting hole 130a is larger than that of the fifth connecting hole 120c, and the axes of the fifth connecting hole 120c and the sixth connecting hole 130a are parallel to the height direction of the vehicle body 200, so that the front part 130 can still be connected to the connecting bracket 120 after moving a certain distance along the length or width direction of the vehicle body 200.

[0059] In some embodiments, such as Figure 7 and Figure 8 As shown, the connecting bracket 120 is provided with a first positioning structure 121, and the front part 130 is provided with a second positioning structure 131 adapted to the first positioning structure 121. The first positioning structure 121 and the second positioning structure 131 are positioned and engaged. When the connecting bracket 120 is precisely installed on the front module 110 with the vehicle body 200 as the reference, the front part 130 can be precisely installed on the connecting bracket 120 through the positioning and engagement of the first positioning structure 121 and the second positioning structure 131. This ensures the positional accuracy of the front part 130 and the vehicle body 200, making it easier for installers to accurately install the front part 130.

[0060] The first positioning structure 121 and the second positioning structure 131 can take various forms. The first positioning structure 121 can be a positioning pointer, and the second positioning structure 131 can be a positioning scale line, or the first positioning structure 121 can be a positioning scale line and the second positioning structure 131 can be a positioning pointer, etc.

[0061] In some embodiments, two front-end components 130 are fixed on the connecting bracket 120, namely a front bumper module and a front continuous combination light module. In these embodiments, such as... Figure 7As shown, a rectangular positioning hole is provided on the front bumper module. The second positioning structure 131 consists of two triangular pointers respectively located in the middle of the two short sides of the rectangular positioning hole. The first positioning structure 121 on the connecting bracket 120 consists of two positioning scale lines, which are located below the two triangular pointers respectively. The distance between two adjacent scale lines is 0.5mm, and the middle one of each positioning scale line is the zero line. When assembling the front bumper module with the connecting bracket 120, the two triangular pointers on the front bumper module are aligned with the zero lines of the two positioning scale lines on the connecting bracket 120. Due to the cumulative front dimension chain, the final assembly position of the front bumper module and the connecting bracket 120 is often not at the zero position. The installer needs to provide the corresponding compensation dimension according to the current size, and then adjust the position of the front bumper module. After aligning the triangular pointers with the corresponding zero lines on the connecting bracket 120, the fifth connecting hole 120c and the sixth connecting hole 130a are fastened through the third connector, thereby achieving precise positioning of the front bumper module on the connecting bracket 120. In these embodiments, as shown... Figure 8 As shown, a square positioning hole is provided on the front through-type combination light module. The second positioning structure 131 consists of positioning scale lines set on the four sides of the square positioning hole, with a spacing of 0.5mm between adjacent scale lines. One of the scale lines in the middle is the zero line. The first positioning structure 121 on the connecting bracket 120 is a cross rib, which is located inside the square positioning hole 200a. When assembling the front through-type combination light module with the connecting bracket 120, the four ends of the cross rib on the connecting bracket 120 are aligned with the four zero lines on the front through-type combination light. Due to the cumulative dimensional chain at the front, the final assembly position of the front through-type combination light module and the connecting bracket 120 is often not at the zero position. Engineers need to provide corresponding compensation dimensions based on the current dimensions, and then adjust the position of the front through-type combination light to align the zero line on the front through-type combination light with the positioning cross rib on the connecting bracket 120. Then, the fifth connecting hole 120c and the sixth connecting hole 130a are fastened through the third connector, thereby achieving precise installation of the front through-type combination light module on the connecting bracket 120.

[0062] To further improve the installation accuracy of the front-end component 130, in some embodiments, such as Figure 4As shown, a second positioning part 111a is provided on the front-end module 110, which is used for positioning with the vehicle body 200. The longitudinal beam 210 assembly generally has high strength but poor formability, making dimensional deviation control difficult and resulting in poor positional error. With this design, the front-end module 110, under the action of the second positioning part 111a, can be positioned and connected with components such as the left and right fenders of the vehicle body 200. Installation is performed using the left and right fenders of the vehicle body 200 as the installation reference, rather than using the longitudinal beam 210 as the installation reference, thus ensuring the installation accuracy of the front-end module 110. The second positioning part 111a can be a positioning plane, a positioning hole, etc., and is not limited in this application.

[0063] In some embodiments, such as Figure 9 and Figure 10 As shown, the connecting bracket assembly fixture 2000 simultaneously positions the front-end module 110 and the connecting bracket 120. A positioning platform is provided in the middle of the connecting bracket assembly fixture 2000, and the lower surface of the positioning platform is a plane. In these embodiments, as... Figure 3 As shown, the second positioning part 111a is a positioning plane provided on the upper surface of the front-end module 110. During installation, the side of the connecting bracket assembly fixture 2000 closest to the vehicle body 2000 is first positioned inside the vehicle body 200. Then, the front-end module 110 is installed, so that the positioning plane on the upper surface of the front-end module 110 and the plane on the lower surface of the positioning platform of the connecting bracket assembly fixture 2000 are in contact. Then, the front-end module 110 and the longitudinal beam 210 are fixed, thereby ensuring the installation position accuracy of the front-end module 110. In these embodiments, after the front-end module 110 is installed, the connecting bracket assembly fixture 2000 is not disassembled. Then, the connecting bracket 120 is installed: the first positioning part 120a on the connecting bracket 120 is positioned and connected with the positioning structure of the connecting bracket assembly fixture 2000 closest to the connecting bracket 120. Then, the compensation bracket 140 is adjusted and the connecting bracket 120 is fixed on the compensation bracket 140. With this design, the front-end module 110 can be installed using components such as the left and right fenders on the vehicle body 200 as installation references, without being affected or minimally affected by the longitudinal beam 210. This allows for precise positioning and assembly of the front-end module 110, ensuring the installation accuracy of the connecting bracket 120 mounted on it. Furthermore, the connecting bracket 120 is also installed using the vehicle body 200 as the installation reference, further ensuring precise positioning and assembly of the connecting bracket 120. This, in turn, ensures the installation accuracy of the front-end component 130. Through this secondary precise positioning and assembly, the problem of poor positional accuracy of the front-end component 130 in the length, width, and height directions of the vehicle body 200 can be systematically solved, significantly improving the perceived quality of the vehicle's front exterior dimensions.

[0064] In some embodiments, such as Figure 4As shown, the front-end module 110 includes a front-end frame 111 and a crash beam assembly 112 connected to each other, and a second positioning part 111a is disposed on the front-end frame 111. Multiple compensation brackets 140 are provided, and the multiple compensation brackets 140 are respectively installed on the front-end frame 111 and the crash beam assembly 112. With this design, both the front-end frame 111 and the crash beam assembly 112 have compensation brackets 140, and the connecting bracket 120 is connected to both the front-end frame 111 and the crash beam assembly 112 simultaneously through the compensation brackets 140, which helps to ensure the reliable connection between the connecting bracket 120 and the front-end module 110.

[0065] In some embodiments, such as Figure 4 As shown, the second positioning part 111a consists of two positioning planes disposed on both sides of the upper surface of the front frame 111 along the width direction of the vehicle 1000.

[0066] In some embodiments, such as Figure 4 As shown, multiple compensation brackets 140 are respectively installed on the end face of the front frame 111 facing the anti-collision beam assembly 112 and the end face of the anti-collision beam assembly 112 facing the connecting bracket 120, with the connecting bracket 120 located on the compensation brackets 140. With this design, all the compensation brackets 140 are located below the connecting bracket 120, supporting the connecting bracket 120, which facilitates the connection between the connecting bracket 120 and the front frame 111 and the anti-collision beam assembly 112, and can, to a certain extent, prevent the compensation brackets 140 from interfering with the installation of the front face parts 130 or other parts on the body 200.

[0067] In some embodiments, such as Figure 4 As shown, along the width direction of the vehicle body 200, four compensation brackets 140 are spaced apart on the end face of the front frame 111 facing the anti-collision beam assembly 112, and three compensation brackets 140 are spaced apart on the end face of the anti-collision beam assembly 112 facing the connecting bracket 120, so as to support the connecting bracket 120 at various points along the width direction of the vehicle body 200.

[0068] In some embodiments, such as Figure 4 As shown, the front frame 111 and the anti-collision beam assembly 112 are fixedly connected at both ends along the width direction of the vehicle body 200 by bolts along the width direction of the vehicle body 200; the compensation bracket 140 is fixedly connected to the front frame 111 and the anti-collision beam assembly 112 by bolts along the length direction of the vehicle body 200; the connecting bracket 120 and the compensation bracket 140 are fixedly connected by bolts along the height direction of the vehicle body 200.

[0069] The following describes the installation and adjustment principles of the front-end assembly 100 of the vehicle in this application:

[0070] During installation, the front-end frame 111 is first mounted on the anti-collision beam assembly 112. Then, the anti-collision beam assembly 112 is fixedly connected to the two longitudinal beams 210 of the vehicle 1000 on both sides along the width direction of the vehicle 1000. When installing the front-end frame 111 and the anti-collision beam assembly 112, a front-end frame assembly fixture can be used to position the front-end frame 111 and the anti-collision beam assembly 112 to minimize positional errors between them. The structure of the front-end frame assembly fixture is known to those skilled in the art. The front-end frame assembly fixture can accurately position the front-end frame 111 and the anti-collision beam assembly 112, ensuring the connection accuracy of the front-end frame 111 and the anti-collision beam assembly 112 in the height, width, and length directions of the vehicle 1000.

[0071] Next, the compensation bracket 140 is installed onto the front frame 111 and the anti-collision beam assembly 112.

[0072] Next, place the connecting bracket 120 onto the compensation bracket 140, and then, as follows: Figure 9 As shown, the mounting bracket assembly fixture 2000 is installed: one side of the mounting bracket assembly fixture 2000 is positioned and engaged with the vehicle body 200, and the other side is positioned and engaged with the first positioning part 120a on the mounting bracket 120. In this way, the mounting bracket 120 is accurately positioned with the vehicle body 200 as the reference.

[0073] Next, adjust the height of the compensation bracket 140. Specifically, loosen the first connector located in the first connecting hole 110a and the second connecting hole 140a, move the compensation bracket 140 along the height direction of the vehicle body 200 so that the upper end of the compensation bracket 140 contacts the connecting bracket 120, and then tighten the first connector.

[0074] After the height of the compensation bracket 140 is adjusted, the connecting bracket 120 is fixedly connected to the compensation bracket 140. Specifically, the second connector is inserted into the third connecting hole 140b and the fourth connecting hole 120b, and the second connector is tightened to fix the connecting bracket 120 and the compensation bracket 140, thereby fixing the connecting bracket 120 and the front-end module 110.

[0075] After the connecting bracket 120 is fixedly connected to the compensation bracket 140, disassemble the connecting bracket assembly fixture 2000. Then, install the front part 130 onto the connecting bracket 120. If the front part 130 is a front through-type combination light module, align the four ends of the positioning "+" rib on the connecting bracket 120 with the four zero-position lines on the front through-type combination light, then insert the third connector into the fifth connecting hole 120c and the sixth connecting hole 130a, and then tighten the third connector to ensure the front through-type combination light module is precisely installed on the connecting bracket 120. If the front part 130 is a front bumper module, align the two triangular pointers on the front bumper module with the zero-position lines of the two positioning scale lines on the connecting bracket 120, then insert the third connector into the fifth connecting hole 120c and the sixth connecting hole 130a, and then tighten the third connector to ensure the front bumper module is precisely installed on the connecting bracket 120.

[0076] This completes the installation of the front-end assembly 100 of the vehicle in this application.

[0077] In summary, the connecting bracket 120 of the vehicle front-end assembly 100 of this application no longer uses the front-end module 110 as a reference, but instead uses the vehicle body 200 as an installation reference through its first positioning part 120a, so that the connecting bracket 120 is accurately positioned in the length, width, and height directions of the vehicle body 200. After accurate positioning, the compensation bracket 140 is adjusted and the connecting bracket 120 and the compensation bracket 140 are connected so that the connecting bracket 120 is accurately installed on the front-end module 110 with the vehicle body 200 as a reference. This ensures the installation accuracy of the front face parts 130 installed on the connecting bracket 120 along the length, width, and height directions of the vehicle body 200, which helps to improve the perceived quality of the front appearance dimensions of the vehicle 1000.

[0078] Based on the same inventive concept, this application also provides a vehicle 1000, including a body 200 and the vehicle front-end assembly 100 provided above in this application. The body 200 includes longitudinal beams 210, and the front-end module 110 of the vehicle front-end assembly 100 is fixedly connected to the longitudinal beams 210. Since the vehicle 1000 includes the vehicle front-end assembly 100 provided above in this application, it naturally has all the beneficial effects of the vehicle front-end assembly 100 of this application, which will not be elaborated here.

[0079] In some embodiments, such as Figure 9As shown, the vehicle body 200 is provided with positioning holes 200a and positioning surfaces 200b. The first positioning part 120a of the vehicle front assembly 100 is positioned and connected with the positioning holes 200a and positioning surfaces 200b. With this design, one side of the connecting bracket assembly fixture 2000 is positioned and engaged with the positioning holes 200a and positioning surfaces 200b on the vehicle body 200, and the other side is positioned and engaged with the first positioning part 120a on the connecting bracket 120, so that the connecting bracket 120 uses the positioning holes 200a and positioning surfaces 200b on the vehicle body 200 as the installation reference.

[0080] In some embodiments, such as Figure 9 As shown, the body 200 includes a left fender and a right fender, both of which are provided with positioning holes 200a and positioning surfaces 200b. Positioning holes 200a and positioning surfaces 200b on the body 200 are generally not provided on the longitudinal beams 210 because the longitudinal beam assembly has poor formability, making dimensional deviation control difficult and resulting in large positional errors.

[0081] Based on the same inventive concept, this application also provides a vehicle assembly method for assembling the vehicle front-end assembly 100 and vehicle 1000 provided above in this application, including the following steps:

[0082] S100, the front-end module 110 is installed on the body 200. Normally, the front-end module 110 is installed on the longitudinal beam 210 of the body 200.

[0083] S200, the connecting bracket 120 and the body 200 are positioned and connected by the connecting bracket assembly fixture 2000. One side of the connecting bracket assembly fixture 2000 is positioned and connected to the body 200, and the other side is positioned and connected to the positioning part of the connecting bracket 120, so that the connecting bracket 120 and the body 200 maintain a precise positional relationship.

[0084] S300, adjust the compensation bracket 140 and connect the compensation bracket 140 and the connecting bracket 120. After the connecting bracket 120 is positioned under the action of the connecting bracket assembly fixture 2000, adjust the position of the compensation bracket 140 so that the compensation bracket 140 can be connected to the connecting bracket 120.

[0085] S400, install the front part 130 onto the connecting bracket 120. After the connecting bracket 120 is precisely installed, install the front part 130 onto the connecting bracket 120.

[0086] In the embodiment where the front-end module 110 includes a front-end frame 111 and a crash beam assembly 112, before step S100, the front-end frame 111 and the crash beam assembly 112 can be installed together offline to minimize the positional error between them. Then, the crash beam assembly 112 is installed on the left and right longitudinal beams 210 using a positioning fixture to further reduce the positional error of the front-end module 110. During installation, to ensure connection accuracy, a front-end frame assembly fixture can be used to assemble the front-end frame 111 and the crash beam assembly 112. This fixture accurately positions the front-end frame 111 and the crash beam assembly 112, ensuring connection accuracy in the vehicle's height, width, and length directions. The specific structure of the front-end frame assembly fixture is known to those skilled in the art, and its structure and dimensions are related to the specific structure and dimensions of the front-end frame 111 and the crash beam assembly 112. Typically, the front frame assembly fixture is equipped with anti-collision beam assembly positioning holes, anti-collision beam assembly positioning blocks, front frame positioning holes, and front frame positioning blocks.

[0087] In embodiments where the front-end module 110 includes a front-end frame 111 and a crash beam assembly 112, during step S100, the crash beam assembly 112 is connected to two longitudinal beams 210 of the vehicle body 200 on both sides along the width direction of the vehicle body 200. In some embodiments, the crash beam assembly 112 has a positioning pin along the length direction of the vehicle body 200 on the side facing the longitudinal beam 210, and pin holes are provided on the longitudinal beam 210 to ensure the connection accuracy between the longitudinal beam 210 and the crash beam assembly 112.

[0088] In some embodiments, after step S300 is completed, the connecting bracket assembly fixture 2000 is disassembled to facilitate the installation of the front part 130.

[0089] In the embodiment where a second positioning part 111a is provided on the front-end module 110, when performing step S100, the connecting bracket assembly fixture 2000 is first positioned and connected to the vehicle body 200, then the second positioning part 111a of the front-end module 110 and the positioning part on the connecting bracket assembly fixture 2000 are positioned and fitted together so that the front-end module 110 is accurately positioned, and then the front-end module 110 is fixed to the vehicle body 200.
