Description

Technical Field

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

[0002] For new energy vehicles, there are new requirements for core elements such as the chassis and battery. The refinement of the vehicle's appearance is also receiving more and more attention. The gaps and surface differences between the front hood, front bumper, and headlights in the front area of ​​the vehicle are particularly sensitive.

[0003] However, the dimensional chain between the front cover, front bumper, and headlights in the aforementioned technologies is relatively long, and the gaps and surface differences between the three are large, which affects the aesthetics of the vehicle's appearance. Utility Model Content

[0004] In view of this, this application provides a bracket assembly and a vehicle to solve the technical problem in the above-mentioned related technologies that the dimensional chain between the front cover, front bumper and headlight is long and the gap surface difference between the three is large, which affects the aesthetic appearance of the vehicle.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] A first aspect of this application provides a support assembly comprising:

[0007] Mounting brackets are used to mount the headlights and front bumper, and are used to connect to the front frame;

[0008] A positioning mechanism is disposed on the mounting frame, the positioning mechanism being used to limit and position the mounting frame in a first direction and a second direction by aligning it with the front cover;

[0009] The first direction is the width direction of the vehicle body, and the second direction is the length direction of the vehicle body.

[0010] This application provides a bracket assembly in which the mounting bracket serves as the core integration platform, simultaneously supporting the installation functions of the headlights and the front bumper, and is connected to the front frame. This eliminates the accumulation of dimensional tolerances caused by step-by-step assembly when the two are installed independently, allowing the headlights and the front bumper to share the same installation reference and reducing internal error sources.

[0011] The positioning mechanism is set on the mounting bracket. It limits and positions the mounting bracket by directly aligning it with the front cover, and associates the position reference of the mounting bracket with the outline of the front cover. This ensures that the headlights and front bumper are accurately assembled relative to the front cover, and achieves the centering assembly of the three components.

[0012] The first direction is defined as the width direction of the vehicle body, and the second direction is defined as the length direction of the vehicle body. This clarifies the specific dimensions of the positioning mechanism for limiting and positioning in two orthogonal directions in the horizontal plane, so that the mounting bracket can be precisely constrained in the width and length directions.

[0013] The mounting bracket and positioning mechanism work together to form an integrated system: the mounting bracket integrates the installation of the headlights and front bumpers to eliminate internal tolerances, and the positioning mechanism positions the entire bracket assembly in the front cover reference system through front cover alignment, so that the headlights, front bumpers and front cover form a direct related assembly chain, thereby absorbing the manufacturing tolerances of parts and the errors in the assembly process, shortening the dimensional chain and improving the accuracy of gap and surface difference.

[0014] In some embodiments of this application, the positioning mechanism includes:

[0015] The main body is mounted on the mounting bracket;

[0016] A first positioning structure is disposed on the main body. The first positioning structure is used to be connected to the locking limit of the front cover to limit the displacement of the main body and the mounting bracket in a first direction.

[0018] The first structural member has one end disposed on the main body and the other end extending toward the latch;

[0019] The second structural member has one end disposed on the main body and the other end extending toward the latch. The first structural member and the second structural member are spaced apart along the first direction and form a positioning groove, which is used to accommodate the latch.

[0021] The second positioning structure is used to abut against the front cover in the second direction to restrict the positioning mechanism and the mounting bracket from moving in the second direction.

[0022] In some embodiments of this application, the second positioning structure includes:

[0023] The first positioning post is disposed on the side of the main body facing away from the first positioning structure;

[0024] The second positioning post is disposed on the same side of the main body as the first positioning post, and the second positioning structure and the first positioning structure are spaced apart along the second direction;

[0025] The first positioning structure and the second positioning structure together abut against the front cover to limit the movement of the positioning mechanism and the mounting bracket along the first direction.

[0026] In some embodiments of this application, the first positioning structure, the second positioning structure, and the main body are an integral structure.

[0027] In some embodiments of this application, the mounting bracket includes:

[0028] Two first positioning pins are used to position and install the two headlights at both ends of the mounting bracket along the second direction, respectively;

[0029] A second locating pin is located between the two first locating pins, and the second locating pin is used to mount the front bumper to the mounting bracket.

[0030] In some embodiments of this application, the mounting bracket is also used for detachable connection to the front-end frame in a third direction, the third direction being perpendicular to the second direction and the first direction.

[0031] In some embodiments of this application, the mounting bracket includes a third positioning post and a fourth positioning post spaced apart along the second direction;

[0032] The positioning mechanism includes two positioning holes spaced apart along the second direction;

[0033] One of the positioning holes is provided corresponding to the third positioning post, and the other positioning hole is provided corresponding to the fourth positioning post, so that the mounting bracket and the positioning mechanism are aligned and installed.

[0034] A second aspect of this application provides a vehicle including a vehicle body, headlights, a front bumper, a front frame, a front hood, and a bracket assembly as described above.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0053] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0054] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0055] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0056] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0057] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0058] The aforementioned technologies involve a long dimensional chain between the front hood, front bumper, and headlights, resulting in significant differences in surface area and gaps between them, which negatively impacts the vehicle's aesthetic appearance. This issue arises because, in traditional assembly processes, the headlights and front bumper are typically mounted independently to the front frame of the vehicle body, lacking a direct positioning connection with the front hood. This independent mounting method leads to an excessively long dimensional chain, causing manufacturing tolerances of each component to accumulate during assembly, making it difficult to control the relative positional accuracy between the headlights and the front bumper. Furthermore, when the front hood is assembled as an independent component, it cannot effectively coordinate the spatial positioning of the headlights and front bumper, resulting in significant fluctuations in surface area and gaps between the three components, leading to inconsistencies. In actual production, this problem not only increases the complexity of assembly and debugging but also fails to meet the stringent standards of high-precision appearance required by modern automobiles, resulting in inconsistent product appearance quality and impacting customer satisfaction.

[0059] Furthermore, the lack of a structural design in the existing technology that can integrate the headlights, front bumper, and front cover into a single assembly has resulted in the long-standing problem of tolerance accumulation.

[0060] To address the aforementioned issues, this application provides a bracket assembly and a vehicle. In this technical solution, the mounting bracket serves as a core integrated platform, simultaneously supporting the installation functions of the headlights and the front bumper, and is connected to the front frame. This eliminates the accumulation of dimensional tolerances caused by step-by-step assembly when the two are installed independently, allowing the headlights and the front bumper to share the same installation reference and reducing internal error sources.

[0061] The positioning mechanism is set on the mounting bracket. It limits and positions the mounting bracket by directly aligning it with the front cover, and associates the position reference of the mounting bracket with the outline of the front cover. This ensures that the headlights and front bumper are accurately assembled relative to the front cover, and achieves the centering assembly of the three components.

[0062] The first direction is defined as the width direction of the vehicle body, and the second direction is defined as the length direction of the vehicle body. This clarifies the specific dimensions of the positioning mechanism for limiting and positioning in two orthogonal directions in the horizontal plane, so that the mounting bracket can be precisely constrained in the width and length directions.

[0063] The mounting bracket and positioning mechanism work together to form an integrated system: the mounting bracket integrates the installation of the headlights and front bumpers to eliminate internal tolerances, and the positioning mechanism positions the entire bracket assembly in the front cover reference system through front cover alignment, so that the headlights, front bumpers and front cover form a direct related assembly chain, thereby absorbing the manufacturing tolerances of parts and the errors in the assembly process, shortening the dimensional chain and improving the accuracy of gap and surface difference.

[0064] The bracket assembly and vehicle provided in this application will now be described with reference to the accompanying drawings and specific embodiments.

[0065] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a bracket assembly 10, which may include a mounting bracket 100 and a positioning mechanism 200.

[0066] Mounting bracket 100 is used to mount headlight 50 and front bumper 60, and is used to connect to front frame 20.

[0067] Positioning mechanism 200 is disposed on mounting bracket 100. Positioning mechanism 200 is used to position mounting bracket 100 in a first direction (e.g., by aligning with front cover 30). Figure 1 (in the X direction) and the second direction (e.g.) Figure 1 Limitation and positioning in the Y direction. The first direction is the width direction of the vehicle body, and the second direction is the length direction of the vehicle body.

[0068] The mounting bracket 100 can be understood as a load-bearing structure, whose main function is to integrate the headlight 50 and the front bumper 60 on the same platform and connect them to the front frame 20. In practical applications, the mounting bracket 100 can achieve the above functions in various ways, such as using an integral structure made of metal stamping, injection molding, or composite materials. Its surface can be designed with mounting holes or slots for fixing the headlight 50 and the front bumper 60, while reserving an interface for connection with the front frame 20.

[0069] The positioning mechanism 200 is a device that can limit the position of the mounting bracket 100, achieving precise positioning of the mounting bracket 100 by aligning it with the front cover 30. Specifically, the positioning mechanism 200 can achieve alignment with the front cover 30 through mechanical contact, magnetic adsorption, or optical alignment. For example, the positioning mechanism 200 can be designed as a clamping structure with elastic elements, or a vacuum adsorption device can be used to temporarily fix it to the front cover 30.

[0070] The first and second directions define the width and length directions of the vehicle body, respectively, clarifying the constraint dimensions of the positioning mechanism 200 in two orthogonal directions within the horizontal plane. In practical applications, the first and second directions can be determined through standard definitions in the vehicle coordinate system, such as dividing the width direction based on the vehicle centerline and dividing the length direction based on the front and rear axes.

[0071] In some embodiments, after the positioning mechanism 200 is aligned with the front cover 30, the positioning mechanism 200 can be removed, leaving only the mounting bracket 100, and the headlight 50 and front bumper 60 on the mounting bracket 100, and the front frame, etc., for assembly. The positioning mechanism 200 can be reused.

[0072] This application provides a bracket assembly 10. In this technical solution, the mounting bracket 100 serves as the core integration platform, simultaneously supporting the installation functions of the headlight 50 and the front bumper 60, and is connected to the front frame 20. This eliminates the accumulation of dimensional tolerances caused by step-by-step assembly when the two are installed independently, allowing the headlight 50 and the front bumper 60 to share the same installation reference and reducing internal error sources.

[0073] The positioning mechanism 200 is set on the mounting bracket 100. By directly aligning with the front cover 30, it limits and positions the mounting bracket 100, and associates the position reference of the mounting bracket 100 with the outline of the front cover 30, so as to ensure that the assembly positions of the headlight 50 and the front bumper 60 relative to the front cover 30 are accurate, and realize the centering assembly of the three.

[0074] The first direction is defined as the width direction of the vehicle body, and the second direction is defined as the length direction of the vehicle body. This clarifies the specific dimensions of the positioning mechanism 200 in the two orthogonal directions in the horizontal plane for limiting and positioning, so that the mounting bracket 100 can be precisely constrained in the width and length directions.

[0075] The mounting bracket 100 and the positioning mechanism 200 work together to form an integrated system: the mounting bracket 100 integrates the installation of the headlight 50 and the front bumper 60 to eliminate internal tolerances, and the positioning mechanism 200 positions the entire bracket assembly 10 in the front cover 30 reference system through the alignment of the front cover 30, so that the headlight 50, the front bumper 60 and the front cover 30 form a directly related assembly chain, thereby absorbing the manufacturing tolerances of parts and the errors in the assembly process, shortening the dimensional chain and improving the accuracy of gap surface difference.

[0076] Reference Figure 1 and Figure 2 In some embodiments, the mounting bracket 100 is also used for mounting to a third party (such as...). Figure 1 The Z-direction is detachably connected to the front-end frame 20, and the third direction is perpendicular to the second and first directions.

[0077] The third direction refers to the vehicle's height, which can be understood as a dimension perpendicular to both the width and length directions of the vehicle body. In practical applications, this definition ensures comprehensive constraints on the mounting bracket 100 in three-dimensional space, avoiding assembly errors caused by an unfixed height direction. Detachable connections can be achieved using bolted, snap-fit, or pin connections, aiming to ensure the stability of the mounting bracket 100 in the height direction while facilitating subsequent maintenance and adjustments through flexible fixing methods.

[0078] This solution ensures that the mounting bracket 100 is fully constrained in three-dimensional space by establishing a detachable connection mechanism in the height direction between the mounting bracket 100 and the front frame 20. This detachable connection between the mounting bracket 100 and the front frame 20 in the third dimension not only guarantees a secure fixation in the height direction, preventing displacement caused by vibration or load during vehicle operation, but also retains flexibility during assembly and maintenance, ensuring that the positioning of the mounting bracket 100 in the height dimension is not affected by external factors.

[0079] Reference Figure 3 and Figure 4 In some embodiments, the mounting bracket 100 may include a third positioning post 130 and a fourth positioning post 140 spaced apart along a second direction. The positioning mechanism 200 may include two positioning holes 240 spaced apart along a second direction. One positioning hole 240 is correspondingly disposed with the third positioning post 130, and the other positioning hole 240 is correspondingly disposed with the fourth positioning post 140, so that the mounting bracket 100 and the positioning mechanism 200 are aligned and installed.

[0080] Specifically, the third positioning post 130 and the fourth positioning post 140 refer to the key structures on the mounting bracket 100 used to achieve precise positioning. They can be implemented using cylindrical, square, or other protruding structures with regular geometric shapes. These positioning posts are spaced apart along the length of the vehicle body to provide a dual-reference point design, avoiding rotational deviations that may be caused by single-point positioning. The positioning hole 240 refers to the through hole or blind hole structure on the positioning mechanism 200 used to mate with the positioning post for precise alignment. It can be implemented using circular, elliptical, or other hole shapes adapted to the shape of the positioning post. The purpose of this hole-post mating design is to constrain the degree of freedom of the positioning mechanism 200 in the length direction, ensuring assembly accuracy.

[0081] This technical solution effectively solves the problem of error accumulation caused by inaccurate relative position during assembly by establishing a precise alignment relationship between the mounting bracket 100 and the positioning mechanism 200. The third positioning post 130 and the fourth positioning post 140, which are spaced apart along the second direction (the length direction of the vehicle body) on the mounting bracket 100, provide a dual reference point design in the critical dimension direction. This spaced arrangement avoids rotational deviations that may be caused by single-point positioning and ensures that the positioning features cover the critical area in the length direction of the vehicle body. The two positioning holes 240, which are spaced apart along the second direction on the positioning mechanism 200, form a matching structure with the positioning posts of the mounting bracket 100. The hole-post mating mechanism constrains the degree of freedom of the positioning mechanism 200 in the length direction.

[0082] The precise matching method, in which one positioning hole 240 is set to correspond to the third positioning post 130 and the other to correspond to the fourth positioning post 140, forces the mounting bracket 100 and the positioning mechanism 200 to be strictly aligned during assembly, eliminating the possibility of relative displacement and thus minimizing installation errors.

[0083] This design not only simplifies the assembly process, but also improves the alignment reliability through the redundancy mechanism of dual-point positioning, ensuring the positional accuracy of the positioning mechanism 200 relative to the mounting bracket 100. This provides a stable foundation for the associated assembly of the headlight 50, the front bumper 60 and the front cover 30, and ultimately optimizes the accuracy and consistency of the gap surface difference.

[0084] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the positioning mechanism 200 may include a main body 210 and a first positioning structure 220.

[0085] The main body 210 is mounted on the mounting bracket 100. The main body 210 refers to the basic load-bearing component of the positioning mechanism 200, which can be made by stamping or injection molding of metal sheet, with the purpose of providing a stable mounting base for the entire positioning mechanism 200.

[0086] The first positioning structure 220 is disposed on the main body 210. The first positioning structure 220 is used to limit the connection with the latch 40 of the front cover 30 to restrict the displacement of the main body 210 and the mounting bracket 100 in the first direction. The first positioning structure 220 can be understood as a mechanical connector with a limiting function. It can be implemented in various forms such as a buckle, a pin, or an elastic clamp. Its purpose is to form a rigid constraint by cooperating with the latch 40 of the front cover 30, thereby precisely controlling the displacement of the mounting bracket 100 in the width direction of the vehicle body.

[0087] This technical solution effectively solves the problem of insufficient displacement control of the mounting frame 100 in the width direction through the coordinated design of the main body 210 and the first positioning structure 220. The main body 210, as the basic carrier of the positioning mechanism 200, is directly fixed to the mounting frame 100, ensuring a stable connection between the entire positioning system and the mounting frame 100, providing a reliable support platform for subsequent positioning functions. The first positioning structure 220 is integrated onto the main body 210, and its core function is to establish a direct limiting connection with the front cover 30 latch 40. This connection method fully utilizes the inherent latch 40 feature of the front cover 30 as a reference benchmark, avoiding the reliance on indirect measurement or adjustment in traditional assembly, thereby forming a rigid constraint in the vehicle body width direction.

[0088] Through the physical limiting effect of the first positioning structure 220 and the latch 40, the displacement of the mounting bracket 100 in the first direction is precisely limited, allowing the integrated installation of the headlight 50 and the front bumper 60 to be directly related to the position of the front cover 30. This absorbs manufacturing tolerances and assembly errors of the components, ultimately improving the precision consistency of the gaps between the front cover 30, the headlight 50, and the front bumper 60. This design not only simplifies the positioning process but also reduces the reliance on additional tooling through structural integration, enhancing the stability and repeatability of the assembly process.

[0089] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the first positioning structure 220 may include a first structural member 221 and a second structural member 222.

[0090] One end of the first structural member 221 is disposed on the main body 210, and the other end extends toward the latch 40. One end of the second structural member 222 is disposed on the main body 210, and the other end extends toward the latch 40. The first structural member 221 and the second structural member 222 are spaced apart along the first direction and form a positioning groove 223, which is used to accommodate the latch 40.

[0091] The first structural component 221 is a part with guiding and limiting functions, which can be made by stamping or injection molding of sheet metal. Its purpose is to simplify the assembly path and improve alignment efficiency by directly pointing to the position of the latch 40. The second structural component 222 is a limiting component used in conjunction with the first structural component 221, and it can be manufactured using the same process as the first structural component 221. Its purpose is to ensure uniform force distribution, prevent unilateral displacement of the latch 40 during positioning, and thus enhance overall limiting stability.

[0092] The first structural member 221 and the second structural member 222 have the same structure. For example, both the first structural member 221 and the second structural member 222 can be columnar structures.

[0093] This solution effectively resolves the contradiction between positioning accuracy and ease of manufacturing by concretizing the first positioning structure 220 into a combination of two independent structural components. One end of the first structural component 221 is located on the main body 210, and the other end extends toward the latch 40. This extension design allows the structural component to directly point to the latch 40, avoiding the need for additional guide components, thereby simplifying the assembly path and improving alignment efficiency. Similarly, the second structural component 222 is located on the main body 210, and the other end extends toward the latch 40. Its symmetrical extension with the first structural component 221 ensures uniform force distribution, prevents the latch 40 from shifting to one side during positioning, and enhances the stability of the limiting position.

[0094] The first structural component 221 and the second structural component 222 are spaced apart along the first direction to form a positioning groove 223. This spaced layout precisely defines the spatial dimensions of the groove, allowing the positioning groove 223 to fit tightly against the outline of the latch 40. By eliminating the physical gap, rigid constraint of displacement in the first direction is achieved, avoiding the shaking problem caused by traditional point contact.

[0095] The positioning groove 223 is used to accommodate the latch 40. After the latch 40 is fully embedded in the groove, it can form a surface contact fit. This not only absorbs the manufacturing tolerance between the latch 40 and the positioning structure, but also ensures the absolute fixation of the mounting bracket 100 in the first direction through the bidirectional constraint of the groove wall. This provides a high-precision benchmark for the integrated installation of the headlight 50 and the front bumper 60, and ultimately improves the consistency of the gap surface difference of the front components of the whole vehicle.

[0096] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the positioning mechanism 200 may further include a second positioning structure 230 disposed on the main body 210.

[0097] The second positioning structure 230 is used to abut against the front cover 30 in the second direction to restrict the positioning mechanism 200 and the mounting bracket 100 from moving in the second direction.

[0098] The second positioning structure 230 is a component that restricts the displacement of the mounting bracket 100 along the length of the vehicle body. It can be implemented using a protruding structure, an elastic clamping element, or a snap-fit ​​limiting element. The main body 210 is the core load-bearing component of the positioning mechanism 200. Its main function is to provide a stable mounting base for the second positioning structure 230 and ensure the relative positional accuracy between the second positioning structure 230 and the first positioning structure 220. The purpose of introducing the second positioning structure 230 is to solve the displacement problem of the mounting bracket 100 in the second direction, thereby improving the assembly accuracy of the front bumper, headlight 50, and front cover 30 along the length of the vehicle body.

[0099] This solution, by introducing a second positioning structure 230, comprehensively solves the displacement problem of the mounting bracket 100 in the second direction, ensuring precise alignment of the front bumper, headlight 50, and front cover 30 in the second direction. The positioning mechanism 200 also includes the second positioning structure 230, expanding its functional dimensions so that it not only covers the limiting requirements in the first direction but also collaboratively handles positioning in the second direction, thus constructing a complete spatial limiting system. The design of the second positioning structure 230 being located on the main body 210 directly integrates the new function into the core component of the positioning mechanism 200, avoiding the introduction of additional connecting parts and reducing the accumulation of errors caused by the assembly process. Simultaneously, the main body 210, as the basic support of the positioning mechanism 200, ensures the stable relative positional accuracy between the second positioning structure 230 and the first positioning structure 220, providing structural assurance for reliable limiting in the second direction.

[0100] The second positioning structure 230 is used for the mechanism of abutting against the front cover 30 in the second direction. It utilizes the front cover 30 as a fixed reference surface for the vehicle body for direct contact positioning. Since the front cover 30 is a stable component of the vehicle's front end, its positional accuracy is high and it is not easily affected by the assembly process. Therefore, the positioning method based on the abutment of the front cover 30 can eliminate the influence of the installation error of the front frame 20, achieving a more accurate transfer of the reference datum. The function of restricting the movement of the positioning mechanism 200 and the mounting bracket 100 in the second direction directly constrains the degree of freedom of the mounting bracket 100 in the second direction, ensuring that the front bumper and headlights 50 maintain strict alignment with the front cover 30 during assembly. This effectively absorbs component tolerances and assembly errors, ultimately improving the consistency of gap surface differences and the overall aesthetic refinement.

[0101] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the second positioning structure 230 may include a first positioning post 231 and a second positioning post 232.

[0102] The first positioning post 231 is disposed on the side of the main body 210 facing away from the first positioning structure 220. The second positioning post 232 is disposed on the same side of the main body 210 as the first positioning post 231, and the second positioning structure 230 and the first positioning structure 220 are spaced apart along the second direction.

[0103] The first positioning structure 220 and the second positioning structure 230 work together to abut against the front cover 30 to limit the movement of the positioning mechanism 200 and the mounting bracket 100 in the first direction.

[0104] The first positioning post 231 refers to a columnar structure installed on the main body 210 to provide support and limiting functions. It can be cylindrical, square, or other geometrically rigid. Its purpose is to provide a stable support point for the positioning mechanism 200 away from interference sources in the width direction. The second positioning post 232 can be understood as another limiting structure used in conjunction with the first positioning post 231. It forms a lever-like constraint layout by being spaced apart from the first positioning post 231 on the same side, which can effectively disperse the force and resist the rotational torque, thereby improving the overall limiting rigidity.

[0105] This solution enhances the limiting capability in the second direction through a dual-positioning-post structure, solving the problem of unstable positioning caused by a single support point. The first positioning post 231 is located on the side of the main body 210 facing away from the first positioning structure 220. Since the first positioning structure 220 is located on the front side of the main body 210 and is used for width-direction limiting, placing the first positioning post 231 on the opposite side avoids mutual interference with the width-direction positioning function. At the same time, it provides a stable support point in the length direction away from the interference source, ensuring that it can independently withstand the abutment force from the front cover 30 during assembly without being affected by the width-direction positioning structure.

[0106] The second positioning post 232 and the first positioning post 231 are located on the same side of the main body 210 and are spaced apart along the length direction. This spaced arrangement forms a lever-type constraint layout. When the two positioning posts abut against the front cover 30 at the same time, they can effectively disperse the force and resist the rotational torque, preventing the positioning mechanism 200 from tilting or sliding in the length direction, thereby improving the limiting rigidity.

[0107] The first positioning post 231 and the second positioning post 232 jointly abut against the front cover 30. Through the dual-point contact mechanism, the original single limiting point is expanded into a multi-point collaborative action. This not only enhances the reliability of the constraint in the length direction, but also eliminates the small gaps that may be generated by single-point contact through structural complementarity. This ensures that the mounting bracket 100 maintains a precise position throughout the assembly process, and ultimately achieves high-precision control of the gap surface difference between the front cover 30, the headlight 50 and the front bumper 60.

[0108] Reference Figure 3 and Figure 4 In some embodiments, the first positioning structure 220, the second positioning structure 230, and the main body 210 are an integral structure.

[0109] In this context, an integrated structure refers to a single component manufactured by integrating multiple functional parts through a molding process. This can be achieved through injection molding, casting, or machining. The purpose of this design is to eliminate the additional tolerances that may be introduced when assembling separate components, ensuring the relative positional accuracy between each positioning point.

[0110] This technical solution integrates the first positioning structure 220, the second positioning structure 230, and the main body 210 into a single structure. The spatial relationship between each positioning point is directly guaranteed by the mold, avoiding positioning deviations caused by accumulated tolerances during the assembly of separate parts. This design ensures precise alignment between the mounting bracket 100 and the front cover 30, maintaining a high degree of consistency in the relative positions of the positioning pins of the headlight 50 and the front bumper 60. This effectively absorbs manufacturing and assembly errors during the assembly process, improving the gap and surface difference accuracy between the front cover 30, the headlight 50, and the front bumper 60.

[0111] Reference Figure 7 In some embodiments, the mounting bracket 100 may include two first positioning pins 110 and a second positioning pin 120.

[0112] Two first positioning pins 110 are used to position and install the two headlights 50 at both ends of the mounting bracket 100 along the second direction. A second positioning pin 120 is located between the two first positioning pins 110 and is used to install the front bumper 60 onto the mounting bracket 100.

[0113] The first positioning pin 110 refers to a positioning structure installed on the mounting bracket 100. It can be a columnar body or a pin with a specific shape, and achieves precise positioning by cooperating with corresponding holes on the headlight 50. The second positioning pin 120 refers to a positioning structure located between the two first positioning pins 110, which can also be implemented in the form of a columnar body or a pin. The purpose of introducing these positioning pins is to provide precise fixing points for the headlight 50 and the front bumper 60, thereby eliminating the dimensional tolerance chain when installed independently.

[0114] This solution integrates a positioning pin structure on the mounting bracket 100, enabling precise correlation control of the mounting positions of the headlight 50 and the front bumper 60, thereby eliminating the dimensional tolerance chain during independent installation and improving assembly consistency.

[0115] Specifically, two first positioning pins 110 are set at both ends of the mounting bracket 100 along the second direction to position the two headlights 50 respectively. According to the overall layout of the mounting bracket 100, the positioning pins are placed at both ends of the length direction to ensure that the headlights 50 are precisely fixed in the symmetrical position in the length direction of the vehicle body, avoiding left and right deviations caused by independent installation. The relative position accuracy between the headlights 50 is uniformly controlled by the bracket, effectively reducing the length of the dimension chain.

[0116] The installation position of the front bumper 60 is directly associated with the installation position of the headlight 50, thereby absorbing the manufacturing tolerances and assembly errors of the parts during the installation process, realizing the coordinated positioning of the front bumper 60 and the headlight 50 in the length direction, and avoiding the cumulative effect of tolerance on the gap surface difference.

[0117] This application embodiment also provides a vehicle, which may include a vehicle body, headlights 50, front bumper 60, front frame 20, front cover 30 and the above-mentioned bracket assembly 10;

[0118] The front frame 20 and the front cover 30 are both located at the head of the vehicle body. The bracket assembly 10 is connected to the front frame 20, and the headlight 50 and the front bumper 60 are located on the bracket assembly 10.

[0119] This technical solution unifies the mounting reference of the headlight 50 and the front bumper 60 to the bracket assembly 10 through integrated design, and associates the positioning of the front cover 30, effectively shortening the dimensional chain to solve the problem of gap surface difference accuracy.

[0120] Specifically, the vehicle body serves as the basic platform to provide installation support, ensuring the positional stability of the front frame 20 and the front cover 30. The headlight 50 is set on the bracket assembly 10 to achieve coordinated positioning with the front bumper 60, avoiding the accumulation of dimensional deviations when installed independently. The front bumper 60 is also set on the bracket assembly 10, forming an integrated assembly unit with the headlight 50, reducing the relative tolerance between the two.

[0121] The front frame 20 is located at the head of the vehicle body, providing a connection interface for the bracket assembly 10 and transmitting structural support. The front cover 30 is located at the head of the vehicle body, establishing a positioning relationship with the bracket assembly 10 to ensure the spatial correlation of the three.

[0122] The bracket assembly 10, as a core integrated component, supports both the headlight 50 and the front bumper 60, and absorbs component tolerances through positioning and matching with the front cover 30. The integrated design of the headlight 50 and the front bumper 60 in the bracket assembly 10 eliminates independent installation links, making the assembly process of the three components form a closed loop.

[0123] These features work together: the bracket assembly 10 acts as an intermediary carrier, positioning and binding the mounting references of the headlight 50 and the front bumper 60 with the front cover 30; the front frame 20 provides vertical fixation; and the front cover 30 provides horizontal reference, together achieving the interconnected assembly of the three, thereby significantly shortening the dimensional chain and improving the accuracy of gap and surface difference.

[0124] In some embodiments, the vehicle may be a gasoline-powered vehicle, or it may be a new energy vehicle, such as a pure electric vehicle (PEV / BEV), a range-extended electric vehicle (REEV), a hybrid electric vehicle (HEV), or a fuel cell electric vehicle. The vehicle may also be any vehicle equipped with a battery.
