Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle lamp structure and a vehicle. Background Technology
[0002] The connection structure in a vehicle headlight is an important component of the vehicle lighting system. The connection structure needs to ensure that the various parts of the headlight do not shift or loosen when the vehicle is in motion, under complex road conditions, such as when driving on a bumpy road.
[0003] In related technologies, the headlight structure uses snap-fit fastening instead of bolt fastening to speed up assembly and reduce the number of parts. However, to ensure reliable connection and fixation of the headlight structure, the dimensions of the snap-fit structure need to be strictly controlled within tolerance range. This places high demands on the precision of the molds, leading not only to increased production costs but also to a higher product defect rate. Utility Model Content
[0004] This application provides a vehicle headlight structure and vehicle, which aims to further reduce the manufacturing cost and difficulty of the connecting parts while ensuring that the headlight components are securely installed through the connecting components, thereby improving the economic efficiency of the headlight structure.
[0005] The specific technical solution is as follows:
[0006] An embodiment of the first aspect of this application provides a vehicle lamp structure, which includes a first component and a second component. The first component is provided with a first connector, and the second component is provided with a second connector. The second connector has a connection hole, and an elastic abutment is provided on the wall of the connection hole. The first connector can be inserted into the connection hole and squeeze the elastic abutment to bend and deform the elastic abutment, and the side of the elastic abutment abuts against the side of the first connector.
[0007] Specifically, during the insertion of the first connector into the connecting hole, the first connector presses against the elastic abutment on the hole wall, causing the elastic abutment to deform. This deformation generates an elastic restoring force, which, due to the first connector being located within the connecting hole, continuously presses against the elastic abutment. This elastic restoring force then continuously acts on the first connector, preventing further movement.
[0008] Based on this, after the elastic abutment is deformed by the compression of the first connector, the side of the elastic abutment comes into contact with the peripheral side of the first connector. In this way, a relative frictional force is generated between the two abutment surfaces along the axial direction of the connecting hole. This relative frictional force can prevent the first connector from moving out of the connecting hole.
[0009] In summary, because the first connecting member compresses the elastic abutment member, a compressive force is generated between them along the radial direction of the connecting hole and a relative frictional force along the axial direction of the connecting hole. Both the compressive force and the relative frictional force prevent the first connecting member from moving relative to the connecting hole, thus achieving the fixing effect on the first connecting member. Compared with the snap-fit connection structure in related technologies, this method, while ensuring a stable and reliable connection, has lower requirements for the structural precision of the connecting member, thereby further reducing the manufacturing cost and difficulty of the connecting member, reducing the product defect rate of the vehicle lamp structure, and improving the production economy of the vehicle lamp.
[0010] In some embodiments, the first connector is a connecting post with a circular radial cross-sectional shape and a cylindrical connecting hole. Furthermore, the diameter of the radial cross-section of the connecting post gradually increases along the direction toward the first component.
[0011] By gradually increasing the diameter of the radial section of the connecting column, the force exerted by the second connector on the connecting column can be continuously increased during the insertion of the connecting column into the connecting hole. This further enhances the fixing effect between the connecting column and the second connector as the connecting column penetrates deeper into the connecting hole, thereby ensuring the reliable connection between the first component and the second component.
[0012] In some embodiments, the connecting hole forms an insertion port on the second connector, and the connecting post is inserted into the connecting hole from the insertion port; an annular boss protruding toward the axis of the connecting hole is formed on the hole wall, one end of the elastic abutment is connected to the side of the annular boss facing away from the insertion port, and the other end of the elastic abutment extends toward the axis of the connecting hole.
[0013] The annular boss provides a mounting position for the elastic abutment on the hole wall and also provides deformation space for the elastic abutment. In other words, when the connecting post is inserted into the connecting hole from the insertion port, the connecting post can compress the elastic abutment in a direction away from the insertion port. After being compressed by the connecting post, the elastic abutment can deform upwards towards the annular boss, thereby abutting against the side of the connecting post. Furthermore, by providing the annular boss, it is easier to mold the elastic abutment structure onto the first connecting member using a mold, thereby further reducing the manufacturing difficulty of the first connecting member and improving the economic efficiency of the headlight structure.
[0014] In some embodiments, the resilient abutment is inclined away from the insertion port. This makes it easier to push and compress the resilient abutment to deform during the insertion of the connecting post from the insertion port into the connecting hole, and facilitates the contact between the side of the resilient abutment and the side of the connecting post.
[0015] In some embodiments, the thickness of the resilient abutment gradually decreases in the direction away from the hole wall. This allows the resilient abutment to deform more easily.
[0016] In some embodiments, there are multiple resilient abutments, which are arranged at circumferential intervals along the connecting hole.
[0017] This design not only provides better fixation for the connecting column, but also ensures that the force on the connecting column is evenly distributed along the circumference within the connecting hole, thereby further guaranteeing the connection stability between the first and second components.
[0018] In some embodiments, the second connector and the resilient abutment are an integral structure.
[0019] This facilitates the forming of the elastic abutment on the second connector, and also further enhances the connection strength at the connection between the elastic abutment and the second connector.
[0020] In some embodiments, a plurality of limiting members are further provided on the side of the first connector, the plurality of limiting members are arranged at intervals along the circumference of the first connector, and the limiting members are in an interference fit with the wall of the connecting hole when the first connector is located in the connecting hole; or, a plurality of limiting members are provided on the wall of the connecting hole, the plurality of limiting members are arranged at intervals along the circumference of the connecting hole, and the limiting members are in an interference fit with the side of the first connector when the first connector is located in the connecting hole.
[0021] When the connecting post is inserted into the connecting hole, the limiting member and the connecting post will undergo elastic deformation due to mutual compression, thereby generating an interaction force between them. This causes the limiting member located on the wall of the connecting hole to tighten the connecting post, thus further preventing the connecting post from moving out of the connecting hole. Therefore, the connection effect between the first connecting member and the second connecting member is further improved, which in turn improves the connection strength between the first and second components of the headlight structure.
[0022] In some embodiments, the limiting member extends axially along the connecting hole. This enhances the limiting effect of the limiting member on the connecting post, thereby further improving the connection strength between the first connecting member and the second connecting member.
[0023] In some embodiments, the limiting element is an elastic element.
[0024] With this design, the limiting component can achieve an interference fit with the connecting column through its own extrusion deformation, which can avoid rigid friction between the limiting component and the connecting column, thereby further extending the service life of the structure.
[0025] In some embodiments, the limiting member and the elastic abutment member are arranged at intervals along the circumference of the connecting hole, thereby further ensuring that the force between the first connecting member and the second connecting member is uniform, thereby further improving the connection stability between the first component and the second component.
[0026] An embodiment of the second aspect of this application provides a vehicle lamp structure, which includes the vehicle lamp structure as described above, wherein the first component is a vehicle lamp decorative frame or lamp housing, and the second component is a vehicle lamp decorative frame.
[0027] The vehicle provided in this application has the same beneficial effects as the aforementioned headlight structure, therefore, it will not be described again here. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0041] In the description of this application, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0043] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0044] As mentioned in the background section, the connection structure in a vehicle headlight is an important component of the vehicle lighting system. The connection structure needs to ensure that the various parts of the headlight do not shift or loosen when the vehicle is in motion, under complex road conditions, such as when driving on a bumpy road.
[0045] Because snap-fit fixing is faster than bolt fixing and can reduce the number of parts, thus lowering product costs, the headlight structure in related technologies uses snap-fit fixing instead of traditional bolt fixing. However, to ensure reliable connection and fixing of the headlight structure, the dimensions of the snap-fit structure need to be strictly controlled within tolerance range. This places high demands on the precision of the molds, leading not only to increased production costs but also to a higher product defect rate.
[0046] Based on the above, the applicant of this application has proposed a technical solution in the embodiments of this application. Specifically, by improving the connecting parts of the vehicle lamp structure, the manufacturing cost and difficulty of the connecting parts are reduced, thereby improving the economy of the vehicle lamp structure.
[0047] The above is the core idea of this application. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0048] like Figures 1 to 4 As shown, an embodiment of the first aspect of this application provides a vehicle lamp structure, which includes a first component 10 and a second component. The first component 10 is provided with a first connector 1, and the second component is provided with a second connector 2. The second connector 2 is provided with a connection hole 21, and the first connector 1 can be inserted into the connection hole 21 accordingly.
[0049] Specifically, the first component 10 and the second component of the headlight structure can be any two parts that need to be connected to each other, such as the connection between the headlight housing and the decorative frame, or the connection between the two decorative frames of the headlight. In this embodiment, the first component 10 is the headlight housing and the second component is the decorative frame, that is, the first connector 1 is formed on the headlight housing and the second connector 2 is formed on the decorative frame. The first connector 1 on the headlight housing can be inserted into the connecting hole 21 on the decorative frame.
[0050] Furthermore, an elastic abutment 22 is provided on the wall of the connecting hole 21. When the first connector 1 is inserted into the connecting hole 21, it can squeeze the elastic abutment 22 to make the elastic abutment 22 bend and deform, and make the side of the elastic abutment 22 abut against the peripheral side of the first connector 1.
[0051] Specifically, the elastic abutment 22 provided on the wall of the connecting hole 21 can protrude from the wall of the connecting hole 21 and extend towards the central axis of the connecting hole 21. During the insertion of the first connector 1 into the connecting hole 21, the first connector 1 will press against the elastic abutment 22 on the hole wall, causing the elastic abutment 22 to deform. Thus, the elastic abutment 22 generates an elastic restoring force due to deformation. Since the first connector 1 is located in the connecting hole 21, it will continuously press against the elastic abutment 22, and the elastic restoring force will continue to act on the first connector 1, preventing further movement. See [link to details] for more information. Figure 3 As shown.
[0052] Based on this, after the elastic abutment 22 is deformed by the compression of the first connector 1, the side of the elastic abutment 22 abuts against the peripheral side of the first connector 1. In this way, a relative frictional force is generated between the two abutment surfaces along the axial direction of the connecting hole 21. This relative frictional force can prevent the first connector 1 from moving out of the connecting hole 21.
[0053] In summary, since the first connector 1 presses against the elastic abutment 22, a pressing force along the radial direction of the connecting hole 21 and a relative frictional force along the axial direction of the connecting hole 21 are generated between the two. Both the pressing force and the relative frictional force will prevent the first connector 1 from moving relative to the connecting hole 21, thereby achieving the fixing effect of the first connector 1.
[0054] Therefore, the headlight structure provided in this application embodiment, by providing a first connector 1 on the first component 10 and a second connector 2 on the second component, and by providing a connecting hole 21 on the second connector 2 to allow the first connector 1 to be inserted accordingly, furthermore, an elastic abutment 22 is provided on the wall of the connecting hole 21. During the process of inserting the first connector 1 into the connecting hole 21, it can squeeze the elastic abutment 22 on the hole wall, causing the elastic abutment 22 to deform and abut against the side surface of the elastic abutment 22 and the peripheral side surface of the first connector 1. In this way, the elastic restoring force generated by the elastic abutment 22 after deformation can be distributed along the connecting hole 21. The radial force acts on the first connector 1. At the same time, since the side of the elastic abutment 22 abuts against the circumferential side of the first connector 1, a relative frictional force is generated at the abutment point along the axial direction of the connecting hole 21. The elastic restoring force and the relative frictional force work together on the first connector 1, thereby preventing the first connector 1 from moving out of the connecting hole 21. Compared with the snap-fit connection structure in related technologies, this method has lower requirements for the structural precision of the connector while ensuring a stable and reliable connection. This can further reduce the manufacturing cost and difficulty of the connector, reduce the product defect rate of the vehicle lamp structure, and improve the production economy of the vehicle lamp.
[0055] It should be noted that the side surface of the elastic abutment 22 refers to the contact surface between the elastic abutment 22 and the first connecting member 1, that is, the surface facing the central axis of the connecting hole 21. Conversely, the side surface of the first connecting member 1, that is, the surface facing the hole wall of the connecting hole 21, i.e., the circumferential surface of the first connecting member 1, can contact the elastic abutment 22 provided on the hole wall and press against each other.
[0056] Furthermore, in some embodiments, the elastic abutment 22 may be made of silicone or rubber to ensure sufficient structural toughness while being able to deform under compression. In a further specific embodiment, the second connector 2 and the elastic abutment 22 may be made of the same material; that is, the second connector 2 and the elastic abutment 22 are an integral structure. This facilitates the molding of the elastic abutment 22 onto the second connector 2 and further enhances the connection strength at the joint between the elastic abutment 22 and the second connector 2.
[0057] For example, both the second connector 2 and the elastic abutment 22 can be made of PBT (Polybutylene terephthalate, a thermoplastic polyester resin) plus glass fiber material.
[0058] like Figure 2 As shown, in some embodiments, the first connector 1 is a connecting post 11 with a circular radial cross-sectional shape, and the connecting hole 21 is a cylindrical hole. In this way, the outer contour shape of the first connector 1 is adapted to the hole shape of the connecting hole 21, thereby enabling the first connector 1 and the connecting hole 21 to be better matched, connected and fixed.
[0059] In a practical implementation, the second connector 2 can also be configured as a cylindrical structure. One end of the cylindrical structure is connected to the surface of the second component, and the other end of the cylindrical structure extends away from the second component. The connecting hole 21 is located at the other end of the cylindrical structure. See [reference needed] for details. Figure 1 As shown.
[0060] Of course, in other possible ways, a part of the second component can be directly formed as the second connector 2, that is, the connecting hole 21 is directly opened on the surface of the second component, which can also achieve the above effect.
[0061] Furthermore, in some embodiments, the diameter of the radial cross-section of the connecting post 11 gradually increases along the direction close to the first component 10. That is, since the position of the elastic abutment 22 on the hole wall is fixed, as the connecting post 11 gradually penetrates deeper into the connecting hole 21, the side of the connecting post 11 gradually approaches the hole wall, and the degree of compression of the elastic abutment 22 by the connecting post 11 gradually increases. Thus, the degree of deformation of the elastic abutment 22 increases, and the resulting elastic restoring force also gradually increases. Furthermore, due to the increased degree of deformation of the elastic abutment 22, the contact surface between the elastic abutment 22 and the connecting post 11 also increases, thus the movement of the first connecting member 1 relative to the connecting hole 21 is subject to greater relative friction.
[0062] Therefore, by gradually increasing the diameter of the radial section of the connecting post 11, the force exerted by the second connecting member 2 on the connecting post 11 can be continuously increased during the process of inserting the connecting post 11 into the connecting hole 21. This can further enhance the fixing effect between the connecting post 11 and the second connecting member 2 as the connecting post 11 goes deeper into the connecting hole 21, thereby further ensuring the reliable connection between the first component 10 and the second component.
[0063] like Figure 5 As shown, in some embodiments, the thickness of the resilient abutment 22 gradually decreases along the direction away from the hole wall. This allows the resilient abutment 22 to deform more easily.
[0064] For example, the thickness of the thickest part of the elastic abutment 22 can be set to 1.2 mm, and the thickness of the elastic abutment 22 can gradually decrease to 0.8 mm along the direction away from the hole wall. In addition, in order to further increase the contact area between the elastic abutment 22 and the connecting post 11, the elastic abutment 22 can be set to have a certain width, for example, the width of the elastic abutment 22 can be set to 5 mm or more.
[0065] like Figure 6 and Figure 7 As shown, in some embodiments, the connecting hole 21 forms an insertion port 211 on the second connector 2, and the connecting post 11 is inserted into the connecting hole 21 through the insertion port 211. Further, an annular boss 23 protruding towards the axis of the connecting hole 21 is formed on the hole wall of the connecting hole 21. One end of the elastic abutment 22 is connected to the side of the annular boss 23 facing away from the insertion port 211, and the other end of the elastic abutment 22 extends towards the axis of the connecting hole 21.
[0066] The annular boss 23 provides a mounting position for the elastic abutment 22 on the hole wall and provides deformation space for the elastic abutment 22. That is, when the connecting post 11 is inserted into the connecting hole 21 from the insertion port 211, the connecting post 11 can press the elastic abutment 22 away from the insertion port 211. After being pressed by the connecting post 11, the elastic abutment 22 can deform upward towards the annular boss, thereby abutting against the side of the connecting post 11. On the other hand, by providing the annular boss 23, it is easier to form the elastic abutment 22 structure on the first connecting member 1 using a mold, thereby further reducing the manufacturing difficulty of the first connecting member 1 and improving the economy of the headlight structure.
[0067] In a specific implementation, the annular boss 23 can extend from one end of the insertion port 211 of the second connector 2 to the middle position of the connecting hole 21, thereby further ensuring the structural strength of the second connector 2, and at the same time, making the gap between the connecting post 11 and the connecting hole 21 smaller, thus making the matching higher.
[0068] In addition, a chamfered structure 212 can be provided at one end of the insertion port 211 to facilitate the alignment between the connecting post 11 and the connecting hole 21, thereby achieving faster assembly. See the figure for details.
[0069] like Figure 3 and Figure 8 As shown, in some embodiments, the elastic abutment 22 may be further configured to be inclined toward the direction away from the insertion port 211. In this way, the connecting post 11 can more easily push and squeeze the elastic abutment 22 to deform during the process of inserting from the insertion port 211 into the connecting hole 21, and facilitate the side of the elastic abutment 22 to abut with the side of the connecting post 11.
[0070] In a specific implementation, the elastic abutment member 22 can be configured to extend at a 40° angle to the axial direction of the connecting hole 21, tilting away from the insertion port 211. Furthermore, the elastic abutment member 22 can be configured as a strip structure with a trapezoidal cross-section, and one side of this trapezoidal strip structure connects to the annular boss. See [reference needed] for details. Figure 6 and Figure 8 As shown. That is to say, the thickness of the connection position between the elastic abutment 22 and the annular boss 23 is relatively large, thereby ensuring the connection strength between the elastic abutment 22 and the annular boss 23. On this basis, the part of the elastic abutment 22 near the connecting post 11 is set as a triangular strip structure, and the tip position is closest to the axis of the connecting hole 21, so that the elastic abutment 22 is easier to deform near the connecting post 11, so as to achieve the corresponding abutment effect with the connecting post 11.
[0071] like Figure 6-8 As shown, in some embodiments, the number of elastic abutment members 22 can be set to multiple, and the multiple elastic abutment members 22 are arranged at intervals along the circumference of the connecting hole 21. This arrangement not only provides a better fixing effect for the connecting post 11, but also further ensures that the force on the connecting post 11 is evenly distributed along the circumference in the connecting hole 21, thereby further ensuring the connection stability of the first component 10 and the second component.
[0072] For example, in this embodiment, the number of elastic abutment members 22 is set to four, and the four elastic abutment members 22 are evenly distributed along the circumference of the connecting hole 21. Of course, in other embodiments, the number of elastic abutment members 22 may also be different.
[0073] like Figure 4 , Figure 6 and Figure 8As shown, in some embodiments, a plurality of limiting members are also provided on the wall of the connecting hole 21. The plurality of limiting members are arranged at intervals along the circumference of the mounting hole, and each limiting member is interference-fitted with the side of the first connecting member 1 when the first connecting member 1 is located in the connecting hole 21.
[0074] In other words, when the connecting post 11 is inserted into the connecting hole 21, the limiting member and the connecting post 11 will undergo elastic deformation due to mutual compression, thereby generating an interaction force between them. This causes the limiting member located on the hole wall of the connecting hole 21 to tighten the connecting post 11, thereby further preventing the connecting post 11 from moving out of the connecting hole 21. This further enhances the connection effect between the first connecting member 1 and the second connecting member 2, and thus improves the connection strength between the first component 10 and the second component of the headlight structure.
[0075] In a specific implementation, the number of limiting members can be set to four, and the four limiting members can be evenly distributed along the circumference of the connecting hole 21. Of course, in other embodiments, the number of limiting members can also be set to other quantities.
[0076] Based on this, the limiting member and the elastic abutment member 22 can be arranged at intervals along the circumference of the connecting hole 21. That is, the limiting member and the elastic abutment member 22 are staggered along the circumference of the connecting hole 21, thereby further ensuring that the force between the first connecting member 1 and the second connecting member 2 is uniform, thereby further improving the connection stability between the first component 10 and the second component.
[0077] In other feasible methods, the limiting member can be set on the side of the first connector 1, and multiple limiting members are arranged at intervals along the circumference of the first connector 1. When the first connector 1 is located in the connecting hole 21, the limiting member is press-fitted with the hole wall of the connecting hole 21, which can also achieve the effect of limiting and fixing.
[0078] like Figure 2 and Figure 4 As shown, in some embodiments, the limiting member is an elastic member. That is, the limiting member achieves an interference fit with the connecting column 11 by generating its own extrusion deformation. This can avoid rigid friction between the limiting member and the connecting column 11, thereby further extending the service life of the structure.
[0079] In practice, the limiting member can be made of the same material as the elastic abutment member 22. Furthermore, when the limiting member is placed on the wall of the connecting hole 21, the limiting member, the elastic abutment member 22, and the second connecting member 2 can be integrally formed, thereby further ensuring the connection strength between the limiting member and the second connecting member 2.
[0080] Furthermore, the limiting member can be configured such that its thickness gradually decreases along the axis toward the connecting hole 21. This ensures the connection strength between the limiting member and the hole wall of the connecting hole 21, while also facilitating contact with the connecting post 11 for compression deformation. In a specific implementation, the limiting member can be configured as a triangular strip structure. Of course, in other embodiments, the limiting member can also be configured as other shapes, such as semicircles, trapezoids, etc.
[0081] like Figure 8 As shown, in some embodiments, the limiting member extends axially along the connecting hole 21, which can improve the limiting effect of the limiting member on the connecting post 11, thereby further improving the connection strength between the first connecting member 1 and the second connecting member 2.
[0082] A second aspect of this application also provides a vehicle, including a body and the aforementioned headlight structure. Specifically, the headlight structure is mounted on the front or rear side of the vehicle body. The headlight structure has been described in detail in the above embodiments and will not be repeated here.
[0083] The vehicle provided in this application embodiment has a first connector 1 on the first component 10 of the headlight structure and a second connector 2 on the second component. A connecting hole 21 is provided on the second connector 2, allowing the first connector 1 to be inserted. Furthermore, an elastic abutment 22 is provided on the wall of the connecting hole 21. During the insertion of the first connector 1 into the connecting hole 21, the elastic abutment 22 on the hole wall is compressed, causing the elastic abutment 22 to deform and its side surface to abut against the peripheral side surface of the first connector 1. Thus, the elastic restoring force generated by the elastic abutment 22 after deformation can propagate along the connecting hole 21. The radial force acts on the first connector 1. At the same time, since the side of the elastic abutment 22 abuts against the circumferential side of the first connector 1, a relative frictional force is generated at the abutment point along the axial direction of the connecting hole 21. The elastic restoring force and the relative frictional force work together on the first connector 1, thereby preventing the first connector 1 from moving out of the connecting hole 21. Compared with the snap-fit connection structure in related technologies, this method has lower requirements for the structural precision of the connector while ensuring a stable and reliable connection. This can further reduce the manufacturing cost and difficulty of the connector, reduce the product defect rate of the vehicle lamp structure, and improve the production economy of the vehicle lamp.
[0084] It should be noted that the vehicle provided in this embodiment should also include other modules or components that enable the vehicle to operate normally. Here, the other modules or components included in the vehicle provided in this embodiment will not be described one by one.
[0085] The vehicle provided in this embodiment has better performance by adopting the headlight structure described above.
