Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a vehicle headlight structure and vehicle. Background Technology

[0002] Automotive headlights need to connect to the vehicle's power supply and controller. This connection requires first using a wiring harness to connect to the internal electronic components of the headlight, and then extending the harness to the outside of the headlight and connecting it to an external connector. To secure the connector, clips are typically installed on the outside of the headlight housing. After connecting the wiring harness to the internal electronic components, the connector must be secured to these clips. This design makes the assembly process for headlights relatively cumbersome, structurally complex, and results in higher material and time costs.

[0003] Therefore, it is necessary to provide a vehicle lighting structure and vehicle to solve or at least alleviate the aforementioned technical problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The existing connection structure between automotive lights and the vehicle's power supply mainly consists of electronic components (PCB substrate), wiring harnesses, connectors, and clips. The electronic components inside the light are connected to the connectors on the outside of the light via the wiring harness to achieve power supply and signal transmission. This connection method requires that after the wiring harness is connected to the electronic components inside the light, the connector must be clipped onto the clips on the outside of the light housing to ensure a stable connection.

[0033] During the production and assembly of the connection structure between the vehicle lights and the vehicle's power supply, the applicant's research revealed that electronic components, wiring harnesses, and connectors need to be produced and prepared separately. The clips and the headlight housing are integrally injection molded. During installation, one end of the wiring harness is first soldered to the electronic component, then the connector is connected to the wiring harness, and finally the connector is clipped into the clip. After conducting research and statistics on vehicle component assembly lines and front-line workers, the applicant found that the assembly efficiency of this connection mechanism is difficult to keep up with the increasingly rapid production pace, and the connection structure itself is relatively complex, which is not conducive to reducing material and time costs.

[0034] Therefore, it is necessary to provide a vehicle lamp structure to solve the above-mentioned technical problems.

[0035] Please see Figures 1 to 4In one embodiment of this utility model, the vehicle lamp structure 100 includes a combined element 1 and a housing assembly 2. The combined element 1 includes a PCB substrate 11 and a connecting terminal 12. One end of the connecting terminal 12 is fixedly mounted on the PCB substrate 11. The housing assembly 2 includes a lamp housing 21, a lamp cover (not shown in the figure), and a connector housing 22. The lamp cover and the lamp housing 21 form an accommodating cavity. The connector housing 22 is disposed on the side of the lamp housing 21 away from the accommodating cavity, and the connector housing 22 is integrally formed with the lamp housing 21. The connector housing 22 is provided with a connecting cavity 221. The lamp housing 21 has a mounting hole 211. The PCB substrate 11 is mounted on the side of the lamp housing 21 facing the accommodating cavity. The other end of the connecting terminal 12 passes through the mounting hole 211 and is disposed in the connecting cavity 221.

[0036] Specifically, the PCB substrate 11 is located inside the lamp housing 21, i.e., inside the vehicle lamp, and integrates all the electronic components required for the vehicle lamp, including LED driver chips, resistors, capacitors, and possibly microcontrollers. One end of the PCB substrate 11 has a connection terminal 12, which is used for electrical connection with an external power supply and controller. Specifically, the connection terminal 12 in the vehicle lamp structure 100 is used to connect to an external plug-in, which connects to the vehicle's overall power supply and control components. The connection method between the connection terminal 12 and the PCB substrate 11 includes soldering and press-fit. The housing assembly 2 is integrally molded using injection molding, and the materials used include one of polycarbonate (PC), polypropylene (PP), polyester (PET), plastic alloy (PC+ABS), acrylonitrile-butadiene-styrene copolymer (ABS), and acrylonitrile-styrene-acrylate copolymer (ASA). The connecting cavity 221 protects the connecting terminal 12 and provides connection space for external plug-ins. The shape of the connecting cavity 221 is designed according to the outer contour of the external plug-ins. In this embodiment, the cross-section of the connecting cavity 221 is a rectangular shape with rounded corners. The connector housings 22 on both sides of the connecting cavity 221 are also provided with guide grooves (not shown in the figure). The guide grooves extend along the extension direction of the connecting cavity 221 to limit the movement path of the external plug-ins and avoid damage to the connecting terminal 12. The vehicle lamp structure 100 formed by the combination of the housing assembly 2 and the combined element 1 does not require a wiring harness and a clip provided on the outside of the lamp housing 21, thus saving material costs. Moreover, the welding process between the wiring harness and the PCB substrate 11 and the snap-fit ​​process between the connector and the clip are eliminated during assembly, thus reducing the assembly time of the vehicle lamp structure 100 and saving time costs.

[0037] In the technical solution provided in this embodiment, the vehicle lamp structure 100 includes a combined element 1 and a housing assembly 2. The combined element 1 includes a PCB substrate 11 and a connecting terminal 12, with one end of the connecting terminal 12 fixedly mounted on the PCB substrate 11. The housing assembly 2 includes a lamp housing 21, a lamp cover, and a connector housing 22. The lamp cover and the lamp housing 21 enclose a receiving cavity. The connector housing 22 is disposed on the side of the lamp housing 21 facing away from the receiving cavity and is integrally formed with the lamp housing 21. The connector housing 22 has a connecting cavity 221. The lamp housing 21 has a mounting hole 211. The PCB substrate 11 is mounted on the side of the lamp housing 21 facing the receiving cavity. The other end of the connecting terminal 12 passes through the mounting hole 211 and is disposed in the connecting cavity 221. With this configuration, the vehicle lamp can have a structure for connecting to an external power supply and controller simply by installing the combined element 1 on the housing assembly 2, without the need for a separate wiring harness to connect to the PCB substrate 11, saving material costs. Furthermore, the vehicle lamp structure 100 is simple to install, saving time costs and ultimately reducing production costs.

[0038] Furthermore, in one embodiment of this utility model, the housing assembly 2 further includes a mounting portion 23, which is integrally formed with the lamp housing 21. The mounting portion 23 is provided with a threaded groove, and the PCB substrate 11 has a fixing hole 111 corresponding to the threaded groove. The vehicle lamp structure 100 also includes a threaded component 3, one end of which passes through the fixing hole 111 and is disposed in the threaded groove (not shown in the figure) to fix the combined component 1 to the housing assembly 2. Please refer to [link to previous text]. Figures 1 to 3 The mounting part 23 protrudes from the lamp housing 21 on the outer side. This design is due to the relatively small thickness of the lamp housing 21. If the combined component 1 and the lamp housing 21 were directly connected using a threaded part 3, vibration during vehicle use could easily cause the connection to loosen, thus reducing the lifespan of the lamp. By making the connecting part protrude, the threaded part 3, after passing through the fixing hole 111 and being installed in the threaded groove, can improve the connection stability of the lamp during vehicle use and reduce loosening caused by vibration. At the same time, placing the protruding part of the mounting part 23 on the outer side of the lamp housing 21 avoids occupying the compact space inside the lamp, which helps to reduce the difficulty of planning the internal space of the lamp.

[0039] In one embodiment of this utility model, there are multiple connecting terminals 12 and mounting holes 211, with each connecting terminal 12 corresponding to a mounting hole 211. This one-to-one correspondence between each connecting terminal 12 and its corresponding mounting hole 211 ensures precise alignment of each component during assembly, reducing assembly errors and improving the stability and reliability of the overall structure. Furthermore, the multiple mounting holes 211 include a differential hole and a standard hole. The projections of the standard hole, the differential hole, and the connecting terminal 12 onto the PCB substrate 11 are respectively a first projection, a second projection, and a third projection. The outer contours of the first and third projections have the same shape and size, while the outer contour of the second projection is larger than that of the third projection. That is, the hole size of the differential hole is larger than the outer contour size of the connecting terminal 12, and there is a clearance fit between the differential hole and the connecting terminal 12. The design of the differential hole ensures the compatibility between the connecting terminal 12 and the mounting hole 211 even when facing manufacturing tolerances or design changes. It also improves the ease of installation of the connecting terminal 12. Due to the presence of the differential hole, even small errors occurring during production and assembly can be corrected, thereby reducing assembly errors. A standard hole is primarily used as a positioning reference for multiple connecting terminals 12 to prevent assembly errors.

[0040] In one embodiment of this utility model, the housing assembly 2 further includes a positioning post 24, which is disposed on the side of the lamp housing 21 facing the PCB substrate 11. The PCB substrate 11 has a positioning hole 112, and the positioning post 24 is configured to cooperate with the positioning hole 112. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The positioning post 24 is located inside the lamp housing 21. One end of the positioning post 24 is integrally formed with the lamp housing 21, and the other end passes through the positioning hole 112 to achieve a quick positioning function. The design of the positioning post 24 and the positioning hole 112 ensures that the PCB substrate 11 is quickly aligned to the correct position during assembly, avoiding installation difficulties caused by the lamp housing 21 obstructing the view of the connection terminal 12 and the mounting hole 211. This reduces adjustments during assembly and improves assembly efficiency. Simultaneously, the cooperation between the positioning post 24 and the positioning hole 112 allows for even force distribution, avoiding the need for only the threaded part 3 and the connection terminal 12 to bear the torque. This reduces structural deformation or damage caused by uneven force distribution and enhances the overall structural stability.

[0041] Please see Figure 4In one embodiment of this utility model, the connector housing 22 includes a main body 222 and a latching part 223. A connecting cavity 221 is formed in the main body 222, and the latching part 223 is disposed on one side of the main body 222. The latching part 223 is used to fix the external plug connected to the connecting terminal 12. In this embodiment, the two sides of the main body 222 along the arrangement direction of the plurality of connecting terminals 12 are referred to as the operating side, and the opposite two sides of the main body 222 other than the operating side are referred to as the fixing side. The latching part 223 is disposed on the fixing side, and the latching part 223 has a symmetrical structure. The cross-section of the connecting cavity 221 is a rectangular shape with rounded corners. The axis of symmetry of any cross-section of the latching part 223 coincides with the axis of symmetry of the cross-section of the connecting cavity 221. Through this arrangement, the connector housing 22 can effectively fix the external plug, ensuring the stability and reliability of the connection and preventing the plug from falling off due to vibration or external force. Furthermore, the main body 222 is connected to the external plug via the snap-fit ​​part 223, which simplifies the installation and disassembly process of the external plug, making it easier for assembly workers to connect and disconnect, thus improving ease of use.

[0042] In addition, the connector housing 22 also includes two flanges 224, which are respectively disposed on opposite sides of the main body 222, and are disposed on different sides from the latching portion 223. Specifically, in this embodiment, the two flanges 224 are respectively disposed on two fixed sides of the main body 222. As an additional part on the main body 222, the flanges 224 can play a reinforcing role, reduce compressive stress, and improve the service life of the main body 222. Furthermore, the flanges 224 serve as positioning features, making it easier for assembly workers to determine the insertion position of the external plug. Moreover, during vehicle maintenance, the flanges 224 can provide both visual and tactile cues, helping maintenance personnel to perform correct assembly in situations where vision is limited or blind operation is required.

[0043] In one embodiment of this utility model, a sealant layer is provided in the gap between the connecting terminal 12 and the mounting hole 211. The sealant layer can be implemented in various ways. In this embodiment, after the connecting terminal 12 is inserted into the mounting hole 211, an assembly worker or robot uses a glue gun to inject sealant into the gap between the mounting hole 211 and the connecting terminal 12. The sealant layer is formed after it dries or is baked dry. Since automotive headlights are exposed to a humid environment for extended periods, the sealant layer effectively prevents mold growth and forms a protective film, preventing moisture and mold from penetrating the headlight's interior. Simultaneously, the sealant layer secures the connection between the connecting terminal 12 and the mounting hole 211, reducing the likelihood of poor connection between the connecting terminal 12 and the external plug due to vibration, and improving connection stability.

[0044] In one embodiment of this utility model, the connector housing 22 includes an opening communicating with the connecting cavity 221. The vehicle lamp structure 100 also includes a flexible ring, which is installed around the opening in the connector housing 22 to improve the sealing between the external plug and the connector housing 22. The flexible ring is installed on the connector housing 22 circumferentially along the opening, and the connection method includes one of adhesive bonding and hot-melt butt welding. After the assembly component 1 is manufactured, the flexible ring is installed on the connector housing 22 and then sent to the assembly process for assembly. The flexible ring is made of one of nitrile rubber, ethylene propylene rubber, and polyurethane rubber. Through this arrangement, a sealing layer is formed between the connector housing 22 around the opening and the external plug that needs to be inserted into the connector housing 22 during assembly, preventing moisture from entering the connector housing 22 and causing the connecting terminal 12 to become damp and corroded or affecting the connection stability between the connecting terminal 12 and the external plug.

[0045] This utility model also proposes a vehicle including a headlight structure 100. The specific structure of the headlight structure 100 is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The vehicle also includes a frame, with a connector housing 22 disposed on the side of the headlight housing 21 facing the frame. This arrangement allows for a simpler vehicle appearance and prevents the sealed parts of the headlight from being exposed to the outside, thereby improving the sealing performance of the headlight.

[0046] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
