Description

Technical Field

[0001] This invention relates to the field of vehicle engineering technology, and in particular to a positioning structure and assembly method for a front-end visual component of an automobile. Background Technology

[0002] In the front-end system of a car, the headlights and the continuous lights are key visual components of the front of the car, each playing an important role. The headlights, as the main lighting structure of the car, are responsible for the driving safety lighting function at night and in low visibility environments. The continuous lights, on the other hand, have become a mainstream automotive exterior decoration and signal prompt component in recent years. They can realize the signal transmission functions such as turn signals and outline indicators, and have become a key element in enhancing the overall design of the vehicle due to their integrated visual effect.

[0003] In current automobile production, the assembly of headlights and continuous lights uses an independent positioning method: each is installed based on a pre-set independent benchmark on the vehicle body, lacking a unified precision coordination control mechanism. This assembly method results in the X-axis surface difference and Y-axis gap between the headlights and continuous lights often exceeding design standards after installation, leading to matching defects such as uneven surface differences and inconsistent gap widths. The X-axis surface difference refers to the surface height deviation along the length of the vehicle, while the Y-axis gap refers to the assembly gap along the width of the vehicle. Summary of the Invention

[0004] (I) The problem to be solved by the present invention is that in the current automobile production process, the independent positioning mode adopted for the assembly of headlights and through lights often results in the X-direction surface difference and Y-direction gap between the headlights and through lights exceeding the design standard after the components are installed, resulting in matching defects such as uneven surface difference and inconsistent gap width.

[0005] (II) Technical Solution To address the aforementioned technical problems, one embodiment of the present invention provides a positioning structure for a front-end visual component of an automobile. The front-end of the automobile includes a front bumper upper bracket, and the visual component includes a through light and headlights located at both ends of the through light. The positioning structure of the front-end visual component of the automobile includes: a mounting bracket, a first positioning part, a second positioning part, and a third positioning part disposed on the front bumper upper bracket, and a fourth positioning part disposed on the headlights. The mounting bracket can be detachably mounted on the front bumper bracket via the first positioning part, the second positioning part, and the third positioning part. The first positioning part, the second positioning part, and the third positioning part respectively position the mounting bracket in the X, Y, and Z directions. The mounting bracket is used to position the headlight in the Y direction. The through light is mounted via the second positioning part and the fourth positioning part, and the second positioning part and the fourth positioning part respectively position the through light in the Y and X directions.

[0006] Optionally, the second positioning part is a positioning hole; both the mounting bracket and the through light are provided with positioning pins corresponding to the position of the second positioning part.

[0007] Optionally, the first positioning part and the second positioning part are both positioning holes, and the third positioning part is a positioning surface; the mounting fixture is provided with positioning pins corresponding to the positions of the first positioning part and the second positioning part, and positioning blocks corresponding to the position of the third positioning part.

[0008] Optionally, both the first positioning part and the second positioning part are elongated holes, with the first positioning part extending along the Y direction and the second positioning part extending along the X direction.

[0009] Optionally, two first positioning parts are configured, with the second positioning part located between the two first positioning parts.

[0010] Optionally, the headlight is further provided with a Y-direction positioning surface; the mounting bracket is provided with a bracket corresponding to the position of the Y-direction positioning surface, and the Y-direction positioning surface can fit with the bracket to position the headlight in the Y direction.

[0011] Optionally, the headlight is further provided with a fifth positioning part; the front of the car also includes a fender, the headlight is rotatably mounted on the fender through the fifth positioning part, and by rotating the headlight, the Y-direction positioning surface can be made to fit with the auxiliary bracket.

[0012] Optionally, the fifth positioning part is a positioning pin, and a positioning hole is provided at a corresponding position on the fender.

[0013] Optionally, the fourth positioning part is a positioning pin; the two ends of the through lamp are respectively provided with positioning holes corresponding to the position of the fourth positioning part.

[0014] Another embodiment of the present invention also provides an assembly method, based on the above-described positioning structure of the automotive front-face visual component, including the following steps: The mounting accessories are installed on the front bumper bracket via the first positioning part, the second positioning part and the third positioning part; The two headlights are mounted to the fenders via the fifth positioning section; Rotate the two headlights so that the Y-axis positioning surface on each headlight aligns with the corresponding bracket on the mounting fixture. Lock the two headlights; Remove the installation accessories from the front bumper upper bracket; Connect the through light to the second positioning part on the upper bracket of the front bumper and the fourth positioning part on each headlight.

[0015] The beneficial effects of this invention are: This invention provides a positioning structure for a front-end visual component of an automobile. The front-end includes a front bumper upper bracket, and the visual component includes a through light and headlights located at both ends of the through light. The positioning structure of the front-end visual component includes: a mounting bracket, a first positioning part, a second positioning part, and a third positioning part disposed on the front bumper upper bracket, and a fourth positioning part disposed on the headlights. The mounting bracket can be detachably mounted on the front bumper upper bracket via the first positioning part, the second positioning part, and the third positioning part, which respectively position the mounting bracket in the X, Y, and Z directions. The mounting bracket is used to position the headlights in the Y direction. The through light is mounted via the second positioning part and the fourth positioning part, which simultaneously position the through light in the Y and X directions, respectively.

[0016] Previously, the front bumper bracket served as a unified load-bearing foundation. The positioning reference for the installation auxiliary fixture was established through the first, second, and third positioning parts. The installation auxiliary fixture then positioned the headlight in the Y direction, ensuring the Y-direction installation accuracy of the headlight. Simultaneously, the through-beam was assembled through the second positioning part shared with the installation auxiliary fixture and the fourth positioning part associated with the headlight, ensuring the Y-direction and X-direction installation accuracy of the through-beam. This achieved a correlated positioning logic between the front bumper bracket, installation auxiliary fixture, headlight, and through-beam, making the assembly reference height of the headlight and through-beam highly coordinated. Compared to existing technologies, through the synergistic effect of multi-directional positioning, the X-direction surface difference and Y-direction gap between the through-beam and headlight can stably meet design standards, significantly reducing matching defects and fundamentally avoiding the problem of uncontrolled surface difference and gap caused by reference fragmentation.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] One embodiment of the present invention provides a positioning structure for a front-end visual component of a car, which is used to assist in assembling the visual component into the front-end system of the car; wherein: the front-end of the car includes a front bumper upper bracket 210, which is a front bumper upper bracket used to connect to the car body; the visual component includes a through light 120 and headlights 110 located at both ends of the through light 120.

[0028] like Figures 1 to 5 As shown, the positioning structure of the automotive front visual component includes: a first positioning part 310, a second positioning part 320, and a third positioning part 330 disposed on the front bumper upper bracket 210, and a fourth positioning part 340 disposed on the headlight 110. The mounting bracket 360 is detachably mounted on the front bumper upper bracket 210 via the first positioning part 310, the second positioning part 320, and the third positioning part 330. After the mounting bracket 360 is mounted on the front bumper upper bracket 210, the first positioning part 310 positions the mounting bracket 360 in the X-axis, the second positioning part 320 positions the mounting bracket 360 in the Y-axis, and the third positioning part 330 positions the mounting bracket 360 in the Z-axis. The mounting bracket 360 positions the headlight 110 in the Y-axis. After the mounting bracket 360 is installed, the headlight 110 can be assembled. After the headlight 110 is assembled, the mounting bracket 360 is removed and the through light 120 is installed. The through light 120 is connected to the front bumper upper bracket 210 through the second positioning part 320. The two ends of the through light 120 are respectively connected to the two headlights 110 through the fourth positioning part 340 on the two headlights 110. The second positioning part 320 is used to position the through light 120 in the Y direction, and the fourth positioning part 340 is used to position the headlights 110 in the X direction.

[0029] The positioning structure of the automotive front-face visual component provided in this embodiment uses the front bumper bracket 210 as a unified load-bearing base. A positioning reference for the mounting bracket 360 is established through the first positioning part 310, the second positioning part 320, and the third positioning part 330. The mounting bracket 360 then positions the headlight 110 in the Y direction, thereby ensuring the installation accuracy of the headlight 110. Simultaneously, the through-beam light 120 is assembled through the second positioning part 320 shared with the mounting bracket 360 and the fourth positioning part 340 associated with the headlight 110. Ensuring the installation accuracy of the through light 120 in both the X and Y directions, the system achieves the associated positioning logic of the front bumper upper bracket 210, installation auxiliary fixture 360, headlight 110, and through light 120. This ensures that the assembly reference heights of the headlight 110 and through light 120 are coordinated. Compared with existing technologies, through the synergistic effect of multi-directional positioning, the X-direction surface difference and Y-direction gap between the through light 120 and headlight 110 can stably meet the design standards, significantly reducing matching defects and fundamentally avoiding the problem of surface difference and gap loss caused by reference separation.

[0030] It should be noted that the X, Y, and Z directions mentioned above are perpendicular to each other. The X, Y, and Z directions are standard spatial coordinate systems used to define the vehicle's spatial attitude and direction of motion; specifically, the X direction is the length direction of the vehicle, the Y direction is the width direction of the vehicle, and the Z direction is the height direction of the vehicle.

[0031] In optional embodiments of the present invention, such as Figures 1 to 3 As shown, the second positioning part 320 is a positioning hole. The mounting bracket 360 has a positioning pin corresponding to the position of the second positioning part 320, and the through-light 120 also has a positioning pin corresponding to the position of the second positioning part 320. During assembly, the mounting bracket 360 is connected to the second positioning part 320 via its positioning pin, and the through-light 120 is connected to the second positioning part 320 via its positioning pin. The second positioning part 320 uses a positioning hole, which, through its engagement with the pin hole, achieves high-precision rigid constraint, strong stability, and high assembly accuracy. Secondly, the pin hole engagement allows for rapid alignment, simplifying the assembly process and reducing operational difficulty and cost. Furthermore, it can adapt to different stress scenarios, improving structural reliability.

[0032] In other alternative embodiments, the second positioning part 320 may also employ a positioning groove, and positioning ribs corresponding to the positioning groove positions are provided on the mounting bracket 360 and the through light 120. In this way, the purpose of positioning the mounting bracket 360 and the through light 120 in the Y direction by the second positioning part 320 and assembling the through light 120 into the front face system through the second positioning part 320 can also be achieved in this embodiment.

[0033] In optional embodiments of the present invention, such as Figures 1 to 3As shown, the first positioning part 310 and the second positioning part 320 both use positioning holes, and the third positioning part 330 is a positioning surface 331. The mounting fixture 360 ​​is provided with a positioning pin corresponding to the position of the first positioning part 310, a positioning pin corresponding to the position of the second positioning part 320, and a positioning block 376 corresponding to the position of the third positioning part 330. During assembly, the positioning pins are inserted into the corresponding positioning holes, and the positioning block 376 is placed directly on the positioning surface 331.

[0034] In this embodiment, the first positioning part 310 and the second positioning part 320 use positioning holes, which, in conjunction with corresponding positioning pins, achieve high-precision rigid constraints, strong stability, and high assembly accuracy through pin-hole engagement. Secondly, the pin-hole engagement allows for rapid alignment, simplifying the assembly process and reducing operational difficulty and cost. Furthermore, it can adapt to different stress scenarios, improving structural reliability. The third positioning part 330 uses a positioning surface 331, which, in conjunction with a positioning block 376, eliminates the complex calibration steps for Z-axis positioning through surface-block engagement, reducing reliance on operator experience, improving production efficiency, and lowering labor costs and assembly error rates.

[0035] Optionally, the main body of the installation accessory 360 is a crossbeam extending along the Y direction. The positioning pin and positioning block 376 can be detachably installed on the crossbeam by means of bolt connection or riveting, or fixedly installed on the crossbeam by means of welding or integral molding.

[0036] Optionally, multiple positioning blocks 376 can be set on the installation fixture 360, with each positioning block 376 spaced apart along the Y direction, such as... Figure 1 As shown, the installation aid 360 is provided with two positioning blocks 376.

[0037] In other alternative embodiments, the first positioning part 310 and the second positioning part 320 may also adopt positioning grooves, and the mounting bracket 360 may be provided with positioning ribs corresponding to the positions of each positioning groove; the third positioning part 330 may also adopt a stepped structure or a boss, etc.

[0038] Preferred, such as Figure 2 As shown, both the first positioning part 310 and the second positioning part 320 adopt elongated oval holes. The first positioning part 310 extends along the Y direction, and the second positioning part 320 extends along the X direction. In this way, it can accurately adapt to the multi-directional assembly tolerance requirements and solve the assembly problems caused by component size deviations. Specifically, the first positioning part 310 is an elongated oval hole extending along the Y direction, which allows the mounting bracket 360 to have a small adjustment space in the Y direction and can be compatible with the size errors of different batches of front bumper bracket 210 or mounting bracket 360. The second positioning part 320 is an elongated oval hole extending along the X direction, which provides a tolerance margin for the X-direction alignment of the mounting bracket 360 and the through light 120, avoiding assembly jamming caused by component machining accuracy deviations.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, two first positioning parts 310 are configured, located at opposite ends of the mounting fixture 360, with a second positioning part 320 positioned between them. This three-point layout provides a stable constraint on the mounting fixture 360, ensuring its position in the X and Y directions remains unchanged. Simultaneously, it ensures even force distribution on the mounting fixture 360, preventing wear or deformation of the positioning parts due to excessive localized stress, thus extending its service life. Preferably, the two first positioning parts 310 are symmetrically arranged about the second positioning part 320, facilitating quick identification of positioning points by workers, reducing alignment time during assembly, and improving operational efficiency.

[0040] Optional, such as Figure 1 and Figure 4 As shown, the headlight 110 is also provided with a Y-direction positioning surface 111; the mounting bracket 360 is provided with a bracket 361 corresponding to the position of the Y-direction positioning surface 111; since there are two headlights 110, in order to avoid the mounting bracket 360 taking up too much space, two brackets 361 are also provided, and the two brackets 361 are located at both ends of the mounting bracket 360 respectively; the Y-direction positioning surface 111 can fit with the bracket 361 to position the headlight 110. By setting auxiliary brackets 361 at both ends of the mounting bracket 360, the headlights 110 on the left and right sides are positioned in the Y direction, ensuring the Y-direction installation accuracy of the headlights 110. Moreover, the headlights 110 are positioned in the Y direction by fitting the Y-direction positioning surface 111 on the headlights 110 with the auxiliary brackets 361, which enhances stability. The tight fit between the Y-direction positioning surface 111 and the auxiliary brackets 361 forms a continuous Y-direction constraint, preventing the headlights 110 from shifting in the Y direction due to localized forces during assembly. This effectively improves the Y-direction positioning accuracy of the headlights 110, thereby ensuring a uniform Y-direction gap between the headlights 110 and the through light 120 and reducing matching defects such as inconsistent gap width caused by inaccurate Y-direction positioning.

[0041] Furthermore, in this embodiment, the headlight 110 is also provided with a fifth positioning part; the aforementioned front face of the car also includes a fender; the headlight 110 can be rotatably mounted to the fender through the fifth mounting part thereon.

[0042] In this embodiment, the fifth positioning part, in cooperation with the fender, can restrict the X-direction displacement of the headlight 110, providing rigid constraint on the position of the headlight 110. The headlight 110 is rotatably mounted on the fender via the fifth positioning part. Then, by rotating the headlight 110, the Y-direction positioning surface 111 on the headlight 110 is brought into contact with the auxiliary bracket 361 on the mounting bracket 360 to complete the Y-direction positioning of the headlight 110. Finally, the headlight 110 is locked, and the assembly of the headlight 110 is completed. The rotatable connection between the fifth positioning part and the fender provides flexible adjustment margin for the Y-direction positioning of the headlight 110, thereby ensuring that the Y-direction positioning surface 111 and the auxiliary bracket 361 are smoothly engaged, avoiding assembly jamming or component damage caused by rigid alignment.

[0043] The fifth positioning part is a positioning pin, and a positioning hole is provided at the corresponding position of the fender. Through the engagement of the pin hole, while ensuring that the headlight 110 can rotate, it can also achieve high-precision rigid constraint, strong stability, and high assembly accuracy; secondly, it can quickly align the headlight 110 during installation, thereby simplifying the assembly process and reducing the difficulty and cost of operation.

[0044] It should be noted that the front of the car includes two fenders, and the two headlights 110 are connected to the two fenders respectively.

[0045] Optional, such as Figure 5 As shown, the fourth positioning part 340 is a positioning pin; both ends of the through lamp 120 are respectively provided with positioning holes corresponding to the positions of the fourth positioning part 340. Through the engagement of the pin holes, high-precision rigid constraints can be achieved, with strong stability and high assembly accuracy; secondly, the through lamp 120 and the headlight 110 can be quickly aligned, thereby simplifying the assembly process and reducing the difficulty and cost of operation.

[0046] The positioning structure of the automotive front-end visual component provided in this embodiment includes two positioning pins on the mounting bracket 360 corresponding to the position of the first positioning part 310, which are X-direction positioning pins 371; and a positioning pin corresponding to the position of the second positioning part 320, which is a first Y-direction positioning pin 372. A positioning hole on the fender corresponding to the position of the fifth positioning part is a first X-direction positioning hole. On the through-light 120, a positioning pin corresponding to the position of the second positioning part 320 is a second Y-direction positioning pin 374; and a positioning hole corresponding to the position of the fourth positioning part 340 is a second X-direction positioning hole 375. The first positioning part 310 and the second positioning part 320 are respectively a first positioning hole 311 and a second positioning hole 321, and the fourth positioning part 340 and the fifth positioning part are respectively a first positioning pin 341 and a second positioning pin. The assembly process of the visual component is as follows: First, the installation accessory 360 is assembled onto the front bumper upper bracket 210; specifically, two X-direction positioning pins 371 are inserted into the two first positioning holes 311 at the corresponding positions, the Y-direction positioning pin is inserted into the second positioning hole 321, and the two positioning blocks 376 are respectively attached to the positioning surfaces 331 at the corresponding positions.

[0047] Subsequently, the two headlights 110 are assembled onto the corresponding fenders; specifically, the second locating pin is inserted into the first X-direction locating hole on the corresponding fender, at which point the headlights 110 can rotate around the axis of the second locating pin.

[0048] Next, rotate each of the two headlights 110 so that the Y-direction positioning surface 111 on each headlight 110 is in contact with the corresponding bracket 361 on the mounting bracket 360. After the Y-direction positioning surface 111 on the headlight 110 is in contact with the corresponding bracket 361 on the mounting bracket 360, lock the headlight 110. At this point, the headlight 110 is assembled and the mounting bracket 360 can be removed from the front bumper bracket 210.

[0049] Finally, the through light 120 is installed; specifically, after the installation accessory 360 is removed from the front bumper bracket 210, the second Y-direction positioning pin 374 is inserted into the second positioning hole 321, and the two second X-direction positioning holes 375 are respectively connected to the first positioning pins 341 on the two headlights 110.

[0050] Another embodiment of the present invention provides an assembly method for assembling a headlight 110 and a through light 120 to the front of a vehicle. The assembly method is based on the positioning structure of the vehicle front visual component in any of the above embodiments. The headlight 110 includes a left headlight 110 and a right headlight 110, and the assembly method includes the following steps: The mounting accessory 360 is mounted on the front bumper upper bracket 210 via the first positioning part 310, the second positioning part 320 and the third positioning part 330; The two headlights 110 are mounted on the fenders via the fifth positioning part; Rotate the two headlights 110 respectively so that the Y-direction positioning surface 111 on each headlight 110 fits into the corresponding position of the auxiliary bracket 361 on the mounting bracket 360; Lock the two headlights 110; Remove the installation accessory 360 from the front bumper upper bracket 210; The through light 120 is connected to the second positioning part 320 on the front bumper upper bracket 210 and the fourth positioning part 340 on each headlight 110.

[0051] The assembly method provided in this embodiment uses two positioning pins on the mounting bracket 360 corresponding to the position of the first positioning part 310 as X-axis positioning pins 371, and a positioning pin corresponding to the position of the second positioning part 320 as a first Y-axis positioning pin 372; a positioning hole on the fender corresponding to the position of the fifth positioning part is a first X-axis positioning hole; a positioning pin on the through lamp 120 corresponding to the position of the second positioning part 320 is a second Y-axis positioning pin 374, and a positioning hole corresponding to the position of the fourth positioning part 340 is a second X-axis positioning hole 375; the first positioning part 310 and the second positioning part 320 are respectively the first positioning hole 311 and the second positioning hole 321, and the fourth positioning part 340 and the fifth positioning part are respectively the first positioning pin 341 and the second positioning pin. The assembly process of the vision component is as follows: First, the installation accessory 360 is assembled onto the front bumper upper bracket 210; specifically, two X-direction positioning pins 371 are inserted into the two first positioning holes 311 at the corresponding positions, the Y-direction positioning pin is inserted into the second positioning hole 321, and the two positioning blocks 376 are respectively attached to the positioning surfaces 331 at the corresponding positions.

[0052] Subsequently, the two headlights 110 are assembled onto the corresponding fenders; specifically, the second locating pin is inserted into the first X-direction locating hole on the corresponding fender, at which point the headlights 110 can rotate around the axis of the second locating pin.

[0053] Next, rotate each of the two headlights 110 so that the Y-direction positioning surface 111 on each headlight 110 is in contact with the corresponding bracket 361 on the mounting bracket 360. After the Y-direction positioning surface 111 on the headlight 110 is in contact with the corresponding bracket 361 on the mounting bracket 360, lock the headlight 110. At this point, the headlight 110 is assembled and the mounting bracket 360 can be removed from the front bumper bracket 210.

[0054] Finally, the through light 120 is installed; specifically, after the installation accessory 360 is removed from the front bumper bracket 210, the second Y-direction positioning pin 374 is inserted into the second positioning hole 321, and the two second X-direction positioning holes 375 are respectively connected to the first positioning pins 341 on the two headlights 110.
