Description

Technical Field

[0001] This application belongs to the field of automotive lighting assembly technology, specifically relating to a positioning and mounting structure and an automobile. Background Technology

[0002] A typical front continuous light assembly includes two headlights arranged side-by-side and a continuous central light strip positioned between them. During installation, the headlights are mounted on the front fender bracket (hereinafter referred to as "front bracket") on the same side using conventional mounting structures (threaded connections, adhesive bonding, etc.). The continuous central light strip is fitted onto the radiator grille mounting plate (hereinafter referred to as "mounting plate") using a YZ-axis positioning structure, and both ends of the continuous central light strip are mounted on the two front brackets respectively using XZ-axis positioning structures. Data experiments and market verification have shown that this structure ensures that the DTS (Dimensional Tolerance Specification) of the headlights and continuous central light strip, and the front continuous light assembly and surrounding components are met.

[0003] The through-type sign light assembly is a new type of front through-type sign light assembly. It adopts the same structure as the common front through-type sign light assembly, and this through-type sign light assembly includes two headlights arranged on the left and right, and a sign light set between the two headlights.

[0004] The main difference between a through-type sign light assembly and a common front through-type sign light assembly is that the sign light of the through-type sign light assembly has a logo icon on it; at the same time, in order to make the logo icon stand out and maintain the visual effect of the through-type structure, the headlights of the through-type sign light assembly are longer in the Y direction compared to the common front through-type sign light assembly.

[0005] Since the structure of a through-type sign light assembly is basically the same as that of a common front through-type sign light assembly, the common positioning method for through-type sign light assemblies is also basically the same as that for common front through-type sign light assemblies. However, the inventors discovered that applying the common front through-type sign light assembly mounting structure to through-type sign light assemblies can easily lead to the following technical problems:

[0006] (1) Common mounting plates adopt an integrated structure and are mounted on the frame at the front of the vehicle body through a lower support cantilever. After the sign light is installed on the mounting plate, due to the superposition of gravity, the mounting plate is prone to deformation exceeding the tolerance on one side, causing overall deviation and ultimately leading to a technical problem of reduced installation accuracy of the sign light.

[0007] (2) After the sign light is placed between the two headlights and connected to the mounting plate, the Y-direction movement of the sign light is restricted. At this time, the distance between the end face of the sign light and the headlight on the same side is difficult to adjust, resulting in the technical problem that the symmetrical difference in the gap between the two sides of the sign light cannot be adjusted.

[0008] In summary, conventional front through-type light assembly installation structures cannot be directly applied to the installation of through-type sign light assemblies. There is an urgent need for a positioning and installation structure that can achieve efficient and stable cooperation between the sign light and the two headlights. Summary of the Invention

[0009] This application provides a positioning and installation structure and a car, which aims to achieve positioning and installation between the marker light body and the headlight body, and between the through-type marker light body group and the whole vehicle.

[0010] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0011] A positioning and mounting structure is provided, including two headlight bodies connected to the front frame of the vehicle body, and a marker light body disposed between the two headlight bodies; wherein the marker light body is connected to the front frame via a mounting member; the mounting member includes a plurality of mounting plates spaced apart along the Y direction of the vehicle body on the front frame;

[0012] The sign light body has multiple upper support cantilever arms extending toward the front frame and corresponding one-to-one with the multiple mounting plates; each upper support cantilever arm is connected to the corresponding mounting plate, and there is an X-direction limiting structure and a Z-direction limiting structure between the upper support cantilever arm and the mounting plate;

[0013] Furthermore, the end of the sign light body along the Y direction of the vehicle body has a Y-direction limiting structure with the headlight body on the same side.

[0014] In one possible implementation, the side of the mounting plate that connects with the upper support cantilever is the upper side of the mounting plate, and the Z-axis limiting structure includes:

[0015] A Z-direction positioning hole is provided on the upper support cantilever, and it penetrates the upper support cantilever along the Z-direction of the vehicle body; and

[0016] The Z-axis locking member is inserted into the Z-axis positioning hole and is connected to the mounting plate to restrict the upper support cantilever from moving away from the mounting plate.

[0017] In one possible implementation, the inner wall of the Z-direction positioning hole has a reserved fracture opening; the reserved fracture opening extends to the end face of the upper support cantilever facing the front end frame, and also extends through the upper support cantilever along the Z-direction of the vehicle body.

[0018] In one possible implementation, the X-direction limiting structure includes:

[0019] A strip-shaped hole is provided on the upper support cantilever, extending through the upper support cantilever along the Z-direction of the vehicle body and extending along the Y-direction of the vehicle body; and

[0020] A limiting rod is fixedly connected to the upper side of the mounting plate and is inserted into the strip hole;

[0021] Specifically, when the limiting rod is inserted into the strip hole, the outer wall of the limiting rod is in contact with the inner side of the strip hole facing the X direction of the vehicle body.

[0022] In one possible implementation, both end faces of the sign light body along the Y direction of the vehicle body are inclined surfaces; each of the inclined surfaces is parallel to the X direction of the vehicle body and is inclined inward from top to bottom; and the side of each headlight body facing the sign light body is parallel to the inclined surface on the same side.

[0023] The Y-direction limiting structure includes a plurality of limiting blocks spaced apart in the vertical direction between the sign light body and the headlight body; wherein each limiting block is fixedly connected to the outer side of the sign light body and also abuts against the headlight body.

[0024] In one possible implementation, the lower side of the sign light body has a plurality of upper protruding ridges corresponding one-to-one with the plurality of mounting plates; each mounting plate has a first lower support cantilever extending toward the sign light body and located on the lower side of the sign light body, and the first lower support cantilever has an upperly extending lower connecting portion that connects with the protruding end of the upper protruding ridge.

[0025] The thickness of the lower docking portion gradually decreases from top to bottom along the horizontal direction.

[0026] In one possible implementation, there is a collapsible space between the sign light body and the mounting plate, and the upper support cantilever has a reinforcing portion located in the collapsible space; there is a gap between the reinforcing portion and the mounting plate, and the side of the reinforcing portion facing the mounting plate has an inclined portion that slopes downwards away from the mounting plate.

[0027] In one possible implementation, there are two mounting plates; the two mounting plates are symmetrically distributed, and their plane of symmetry is parallel to the XZ plane of the vehicle body and coincides with the midpoint of the vehicle body along the Y direction.

[0028] In one possible implementation, the mounting plate further includes:

[0029] The second lower support cantilever is fixedly mounted on the mounting plate, extending toward the headlight body on the same side and located below the headlight body; and

[0030] A support portion is fixedly mounted on the mounting plate, and is located on the side of the mounting plate facing the other mounting plate;

[0031] Each of the support portions has an X-direction reserved hole extending along the X direction of the vehicle body between it and the mounting plate; and the sign light body has two alignment portions adapted to abut against the two support portions respectively.

[0032] In this embodiment, the initial positioning of the marker light body in the Y direction of the vehicle body is achieved by connecting multiple upper support cantilever arms and multiple mounting plates. Based on this, the position of the marker light body in the X and Z directions of the vehicle body is limited by the X and Z direction limiting structures. Furthermore, by finely adjusting the marker light body along the Y direction of the vehicle body and connecting it through the Y direction limiting structure, the complete positioning of the marker light body in the Y direction of the vehicle body can also be achieved.

[0033] Compared with the prior art, the positioning and installation structure provided in this embodiment has multiple mounting plates, and the multiple mounting plates act simultaneously on the positioning of the sign light body. Therefore, it can avoid the defect of reduced installation accuracy of the sign light body caused by the excessive deformation of one side of the mounting plate. At the same time, when the sign light body is connected to the mounting plate, the sign light body can still be finely adjusted along the Y direction of the vehicle body to ensure that the symmetrical difference of the gap on both sides of the sign light body can be effectively adjusted.

[0034] The technical solution adopted in this application also provides a car, including the positioning and mounting structure proposed in any of the foregoing claims.

[0035] The beneficial effects of the automobile provided in this embodiment are the same as those of the aforementioned positioning and mounting structure, and will not be repeated here. Attached Figure Description

[0048] To make the technical problems, technical solutions, and beneficial effects to be solved by 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 are not intended to limit the scope of this application.

[0049] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0050] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., 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, they should not be construed as limitations on this application.

[0051] Furthermore, 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 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 two or more, unless otherwise explicitly specified.

[0052] For ease of description, in this embodiment, the width direction of the vehicle body (i.e., the arrangement direction of the driver's seat and the passenger seat) is defined as the Y-direction of the vehicle body, the length direction of the vehicle body (i.e., the arrangement direction of the front and rear of the vehicle body) is defined as the X-direction of the vehicle body, and the height direction of the vehicle body (i.e., the arrangement direction of the bottom and the roof of the vehicle body) is defined as the Z-direction of the vehicle body.

[0053] Please refer to the following: Figures 1 to 10 The positioning and mounting structure provided in this application will now be described. The positioning and mounting structure proposed in this application includes two headlight bodies 1 and a marker light body 2.

[0054] Both headlight bodies 1 are connected to the front frame of the vehicle body. Specifically, the connection method includes fixing the headlight body 1 to the front fender bracket on the same side, ensuring the light source orientation of the headlight body 1 meets requirements. Simultaneously, the front of both headlight bodies 1 extends along the Y-direction of the vehicle body. In this embodiment, the adjacent sides of the two headlight bodies 1 are defined as the inner sides of the headlight bodies 1, and the opposite sides of the two headlight bodies 1 are defined as the outer sides of the headlight bodies 1.

[0055] The marker light body 2 is positioned between the two headlight bodies 1, and its two ends along the Y direction of the vehicle body are adjacent to the inner sides of the two headlight bodies 1 respectively; the marker light body 2 has a LOGO icon to achieve the technical purpose of the logo; and there are certain requirements for the distance between the inner side of the adjacent headlight body 1 and the outer end face of the marker light body 2, which is usually a 0.5mm gap.

[0056] The sign light body 2 is connected to the front frame via a mounting component; specifically, this mounting component includes multiple mounting plates 3 spaced apart along the Y direction of the vehicle body on the front frame, and the mounting plates 3 are connected to the front frame in a conventional fixed connection manner.

[0057] The sign light body 2 has multiple upper support cantilever arms 7 extending toward the front frame and corresponding one-to-one with multiple mounting plates 3; each upper support cantilever arm 7 is connected to the corresponding mounting plate 3, and there is an X-direction limiting structure 4 and a Z-direction limiting structure 5 between the upper support cantilever arm 7 and the mounting plate 3.

[0058] When the upper support arm 7 and the mounting plate 3 are connected by the X-direction limiting structure 4, relative movement between the upper support arm 7 and the mounting plate 3 along the X-direction of the vehicle body can no longer occur; similarly, when the upper support arm 7 and the mounting plate 3 are connected by the Z-direction limiting structure 5, relative movement between the upper support arm 7 and the mounting plate 3 along the Z-direction of the vehicle body can no longer occur.

[0059] Furthermore, the end of the marker light body 2 along the Y direction of the vehicle body and the headlight body 1 on the same side have a Y-direction limiting structure 6; when the marker light body 2 and the headlight body 1 are connected by the Y-direction limiting structure 6, the marker light body 2 and the headlight body 1 can no longer move relative to each other along the Y direction of the vehicle body.

[0060] In this embodiment, the initial positioning of the marker light body 2 in the Y direction of the vehicle body is achieved by connecting multiple upper support cantilever arms 7 and multiple mounting plates 3. On this basis, the position of the marker light body 2 in the X and Z directions of the vehicle body is limited by the X-direction limiting structure 4 and the Z-direction limiting structure 5. Furthermore, by finely adjusting the marker light body 2 along the Y direction of the vehicle body and connecting it through the Y-direction limiting structure 6, the complete positioning of the marker light body 2 in the Y direction of the vehicle body can also be achieved.

[0061] Compared with the prior art, the positioning and installation structure provided in this embodiment has multiple mounting plates 3, and multiple mounting plates 3 act simultaneously on the positioning of the sign light body 2. Therefore, it can avoid the defect of reduced installation accuracy of the sign light body 2 caused by the excessive deformation of one side of the mounting plate 3. At the same time, when the sign light body 2 is connected to the mounting plate 3, the sign light body 2 can still be finely adjusted along the Y direction of the vehicle body to ensure that the symmetry difference of the gap on both sides of the sign light body 2 can be effectively adjusted, and at the same time, the DTS between the headlight body 1 and the sign light body 2, and between the lamp and the surrounding parts can be achieved.

[0062] It should be noted that DTS stands for "Dimensional Technical Specifications". The main purpose of this specification is to define procedures, changing requirements, clearances, surface differences, and related tolerances during the automotive design process to ensure product quality.

[0063] In some embodiments, such as Figure 2As shown, the side of the mounting plate 3 that connects with the upper support cantilever 7 is the upper side of the mounting plate 3. When the mounting plate 3 connects with the upper support cantilever 7, the mounting plate 3 provides support to the upper support cantilever 7, that is, it restricts the downward movement of the upper support cantilever 7.

[0064] In this embodiment, the Z-direction limiting structure 5 includes a Z-direction positioning hole 51 and a Z-direction locking member 52.

[0065] Z-direction positioning hole 51 is provided on the upper support arm 7 and extends through the upper support arm 7 along the Z direction of the vehicle body.

[0066] The Z-direction locking member 52 is inserted into the Z-direction positioning hole 51 and is connected to the mounting plate 3 to restrict the movement of the upper support cantilever 7 away from the mounting plate 3; combined with the restriction of the upper support cantilever 7 on downward movement by the mounting plate 3 mentioned above, the relative movement between the marker light body 2 and the mounting plate 3 along the Z-direction of the vehicle body is restricted.

[0067] It should be noted that, in this embodiment, the Z-direction locking member 52 includes a locking bolt and a locking nut; during assembly, the locking bolt is inserted into the Z-direction positioning hole 51 from top to bottom, and the lower end of the locking bolt passes through the mounting plate 3 and extends out; the locking nut and the extended part of the locking bolt are threadedly connected, and the locking nut abuts against the lower side of the mounting plate 3.

[0068] To comply with regulation GB24550, in some embodiments, such as Figure 4 As shown, the inner wall of the Z-direction positioning hole 51 has a reserved fracture opening 511. This reserved fracture opening 511 extends to the end face of the upper support cantilever 7 facing the front frame, and also extends along the Z-direction of the vehicle body to the end of the upper support cantilever 7 facing the mounting plate 3. This allows the aforementioned Z-direction locking member 52 to be squeezed into the reserved fracture opening 511 during a collision, increasing the size of the reserved fracture opening 511 and damaging the upper support cantilever 7, thereby reducing injuries to personnel caused by the collision. It should be noted that the width of this reserved fracture opening 511 along the Y-direction of the vehicle body is smaller than the cross-sectional circle diameter of the aforementioned bolt, to ensure the effect of the bolt in restricting the upward movement of the upper support cantilever 7 relative to the mounting plate 3.

[0069] It should be noted that the regulation GB24550 mentioned here refers to the new version of the national standard "Collision Protection of Pedestrians by Automobiles" approved and issued by the State Administration for Market Regulation and the Standardization Administration of China. This standard was proposed by the Ministry of Industry and Information Technology and revised under the leadership of the National Automotive Standardization Technical Committee. It will be officially implemented on January 1, 2025.

[0070] The national standard "Collision Protection of Motor Vehicles for Pedestrians" is under the jurisdiction of the Ministry of Industry and Information Technology. It mainly clarifies the scope of application for vehicles, changes the pedestrian protection test area and lower leg impactor, specifies its technical requirements and test methods, and adds technical content such as the test method for the windshield test area. It provides strong standard support for improving the collision protection performance of motor vehicles for pedestrians, reducing pedestrian injuries and deaths in road accidents, and ensuring the safety of pedestrians. Furthermore, the "Collision Protection of Motor Vehicles to Pedestrians" mainly applies to M1 and N1 category vehicles (where M1 category vehicles refer to passenger vehicles with four or three wheels, a manufacturer-specified maximum gross weight exceeding 1 ton, and more than 8 passenger seats; N1 category vehicles refer to freight vehicles with a maximum design gross weight not exceeding 3500 kg). However, this category does not include: M1 category vehicles where the driver's seat R-point is located in front of the transverse plane of the front axle center or the horizontal distance between the driver's seat R-point and the transverse plane of the front axle center is not greater than 1100 mm, and the maximum gross weight is greater than 2500 kg; and N2 category vehicles where the driver's seat R-point is located in front of the transverse plane of the front axle center or the horizontal distance between the driver's seat R-point and the transverse plane of the front axle center is not greater than 1100 mm.

[0071] In some embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, the X-direction limiting structure 4 includes a strip hole 41 and a limiting rod 42.

[0072] The strip hole 41 is provided on the upper support cantilever 7, which passes through the upper support cantilever 7 along the Z direction of the vehicle body and extends along the Y direction of the vehicle body; in actual manufacturing, a rubber strip can also be connected to the inner wall of the strip hole 41 to avoid structural damage and aging caused by hard contact.

[0073] The limiting rod 42 is fixedly connected to the upper side of the mounting plate 3; when the upper support cantilever 7 and the mounting plate 3 are connected, specifically when the sign light body 2 is moved from top to bottom, this limiting rod 42 is suitable for insertion into the strip hole 41.

[0074] Since the strip hole 41 adopts a structure that extends along the Y direction of the vehicle body and its width remains unchanged in the X direction of the vehicle body, when the limiting rod 42 is inserted into the strip hole 41, the outer wall of the limiting rod 42 is connected to the inner side of the strip hole 41 facing the X direction of the vehicle body, and the limiting rod 42 can also move relative to the strip hole 41 along the Y direction of the vehicle body to ensure the relative movement of the upper support cantilever 7 and the mounting plate 3 along the Y direction of the vehicle body.

[0075] It should be noted that, in this embodiment, by adopting the aforementioned Z-direction limiting structure 5 and X-direction limiting structure 4, the Z-direction limiting and X-direction limiting of the sign light body 2 can be achieved simultaneously. Specifically:

[0076] When the sign light body 2 is inserted from top to bottom into the space between the two headlight bodies 1, and the upper support cantilever 7 and the mounting plate 3 come into contact, the assembly position of the Z-direction positioning hole 51 and the Z-direction locking member 52 is locked. At this time, the Z-direction locking member 52 and the mounting plate 3 can be connected to ensure the Z-direction limit of the sign light body 2. At the same time, the limit rod 42 is inserted from bottom to top into the strip hole 41 to ensure the X-direction limit of the sign light body 2.

[0077] The limit of the sign light body 2 in the X direction of the vehicle body does not require special operation by personnel, while the limit of the sign light body 2 in the Z direction of the vehicle body requires personnel to tighten the bolts or nuts; that is to say, in the initial process of installing the sign light body 2, the operator only needs to perform special treatment on the Z-direction limit structure 5 to simultaneously achieve the Z-direction limit and X-direction limit of the sign light body 2.

[0078] In other embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, the X-direction limiting structure 4 includes a strip hole 41 and a limiting rod 42, and the Z-direction limiting structure 5 includes a Z-direction positioning hole 51 and a Z-direction locking member 52.

[0079] Both the strip hole 41 and the Z-direction positioning hole 51 are provided on the upper support cantilever 7; wherein, the strip hole 41 penetrates the upper support cantilever 7 along the Z direction of the vehicle body and extends along the Y direction of the vehicle body; the Z-direction positioning hole 51 penetrates the upper support cantilever 7 along the Z direction of the vehicle body and adopts a circular hole structure.

[0080] The limiting rod 42 and the Z-direction locking member 52 are both fixedly connected to the upper side of the mounting plate 3. When the upper support cantilever 7 and the mounting plate 3 are connected, specifically when the sign light body 2 is moved from top to bottom, the limiting rod 42 is suitable for insertion into the strip hole 41 and the Z-direction locking member 52 is suitable for insertion into the Z-direction positioning hole 51 (and the Z-direction locking member 52 is connected to the mounting plate 3 to restrict the movement of the upper support cantilever 7 away from the mounting plate 3).

[0081] By adopting this technical solution, the loading of the X-direction limiting structure 4 and the Z-direction limiting structure 5 can be achieved simultaneously, which optimizes the steps in the actual assembly of the device and improves the assembly efficiency of the device.

[0082] In some embodiments, such as Figure 3 and Figure 5 As shown, both end faces of the sign light body 2 along the Y direction of the vehicle body are inclined surfaces; that is, the sides of the sign light body 2 facing the two headlight bodies 1 are inclined surfaces.

[0083] In this embodiment, each inclined surface is parallel to the X-direction of the vehicle body and is inclined inward from top to bottom; furthermore, the side of each headlight body 1 facing the marker light body 2 is parallel to the inclined surface on the same side; that is, during the process of inserting the marker light body 2 into the gap between the two headlight bodies 1 from top to bottom, the gap distance between the marker light body 2 and the headlight body 1 remains consistent; at the same time, the adjacent surfaces of the two headlight bodies 1 form a V-shaped structure to avoid contact damage between the right angle and the inclined surface, and also to enable the two headlight bodies 1 to guide the marker light body 2 longitudinally and ensure the installation efficiency of the marker light body 2.

[0084] Combining the aforementioned Z-direction limiting structure 5 and X-direction limiting structure 4, each inclined surface of the marker light body 2 and the inner side of the headlight body 1 on the same side can form a spatial constraint along the Y direction of the vehicle body. This is to cooperate with the operation step mentioned above of inserting the marker light body 2 from top to bottom between the two headlight bodies 1, so as to achieve the initial adjustment of the position of the marker light body 2 along the Y direction of the vehicle body, making the subsequent positioning of the marker light body 2 in the Y direction of the vehicle body simpler and faster.

[0085] The aforementioned Y-direction limiting structure 6 includes multiple limiting blocks spaced vertically between the marker light body 2 and the headlight body 1. Specifically, there are two sets of limiting blocks, each set positioned at one end of the marker light body 2 facing the Y-direction of the vehicle body. Each set includes several limiting blocks, with an equal number of blocks in both sets, symmetrically arranged with respect to the XZ plane of the vehicle body. When multiple limiting blocks are present on one side, they are spaced vertically, and adjacent blocks can be positioned at different X-direction locations. In this embodiment, four limiting blocks are divided into two equal sets. The two sets are fixed to both sides of the marker light body 2, and each set includes two blocks spaced vertically along the Z-direction of the vehicle body. Each limiting block is fixedly connected to the outer surface of the marker light body 2 and also abuts against the headlight body 1. The connecting and abutting surfaces of the limiting blocks are parallel to the end face of the marker light body 2 facing the Y-direction of the vehicle body.

[0086] The reason for this design is to complement the guiding effect of the V-shaped structure formed by the two headlight bodies 1 mentioned above. When the sign light body 2 is inserted into the space between the two headlight bodies 1 from top to bottom, multiple limiting blocks enter one after another. After the sign light body 2 is in place, each limiting block abuts against the inner side of the headlight body 1 on the same side, thereby restricting the movement of the sign light body 2 along the Y direction of the vehicle body.

[0087] Since both end faces of the marker light body 2 along the Y direction of the vehicle body are inclined, the two limiting blocks on the same horizontal plane will not simultaneously contact the inner sides of the headlight bodies 1 on both sides before the marker light body 2 is in place. This design can largely avoid the impact of the loading process of the marker light body 2 on the stable arrangement of the headlight bodies 1.

[0088] In some other embodiments, the two end faces of the marker light body 2 along the Y direction of the vehicle body are inclined, while the side of each headlight body 1 facing the marker light body 2 is flat.

[0089] In this embodiment, each inclined surface is parallel to the X-direction of the vehicle body and is inclined inward from top to bottom; that is, during the process of inserting the sign light body 2 into the gap between the two headlight bodies 1 from top to bottom, the gap between the sign light body 2 and the headlight body 1 is first large and then small, so as to facilitate the insertion of the sign light body 2 into the headlight body 1.

[0090] It should be noted that, when using this embodiment, the standard gap (0.5mm) between the sign light body 2 and the headlight body 1 specifically refers to the gap between the upper end of the sign light body 2 and the headlight body 1, that is, the minimum gap between the sign light body 2 and the headlight body 1.

[0091] Based on this, the aforementioned Y-direction limiting structure 6 includes multiple limiting blocks made of elastic material, spaced vertically between the sign light body 2 and the headlight body 1. Specifically, there are two sets of limiting blocks, each set positioned at one end of the sign light body 2 facing the vehicle body in the Y direction. Each set includes several limiting blocks, with an equal number of blocks in both sets, symmetrically arranged with respect to the vehicle body's XZ plane. When multiple limiting blocks are present on one side, they are spaced vertically, and adjacent blocks can be positioned at different X-direction locations. The volume of the blocks increases sequentially from top to bottom. During the downward movement of the sign light body 2, the lower limiting block undergoes significant deformation to quickly align the relative positions of the sign light body 2 and the headlight body 1.

[0092] In this embodiment, there are four limiting blocks, which are equally divided into two groups. The two groups of limiting blocks are fixed on both sides of the marker light body 2, and each group of limiting blocks includes two limiting blocks spaced apart along the Z-direction of the vehicle body. Each limiting block is fixedly connected to the outer side of the marker light body 2 and also abuts against the headlight body 1. Furthermore, the connecting surface of the limiting block is an inclined surface parallel to the end face of the marker light body 2 facing the Y-direction of the vehicle body, and the abutting surface of the limiting block is a plane parallel to the Z-direction of the vehicle body.

[0093] In some other embodiments, each headlight body 1 has an inclined surface on the side facing the marker light body 2, while the two end faces of the marker light body 2 along the Y direction of the vehicle body are flat.

[0094] In this embodiment, each inclined surface is parallel to the X-direction of the vehicle body and is inclined outward from top to bottom; that is, during the process of inserting the sign light body 2 into the gap between the two headlight bodies 1 from top to bottom, the gap between the sign light body 2 and the headlight body 1 is first large and then small, so as to facilitate the insertion of the sign light body 2 into the headlight body 1.

[0095] It should be noted that, when using this embodiment, the standard gap (0.5mm) between the sign light body 2 and the headlight body 1 specifically refers to the gap between the lower end of the sign light body 2 and the headlight body 1, that is, the minimum gap between the sign light body 2 and the headlight body 1.

[0096] Based on this, the aforementioned Y-direction limiting structure 6 includes multiple limiting blocks made of elastic material, spaced vertically between the sign light body 2 and the headlight body 1. Specifically, there are two sets of limiting blocks, each set positioned at one end of the sign light body 2 facing the vehicle body in the Y direction. Each set includes several limiting blocks, with the number of blocks in both sets being equal and symmetrically arranged with respect to the vehicle body's XZ plane. When there are multiple limiting blocks on one side, these blocks are spaced vertically, and adjacent blocks can be positioned at different X-direction locations. The volume of the blocks decreases sequentially from top to bottom. During the downward movement of the sign light body 2, the limiting blocks do not contact the headlight body 1 until the sign light body 2 is positioned, achieving the technical objective of supporting the sign light body 2 with the inclined surface of the headlight body 1 through the limiting blocks, thus realizing a suspension effect for the sign light body 2.

[0097] In this embodiment, there are four limiting blocks, and the four limiting blocks are equally divided into two groups; the two groups of limiting blocks are fixed on both sides of the marker light body 2, and each group of limiting blocks includes two limiting blocks spaced apart along the Z-direction of the vehicle body. Each limiting block is fixedly connected to the outer side of the marker light body 2, and it also abuts against the headlight body 1; furthermore, the connecting surface of the limiting block is a plane parallel to the Z-direction of the vehicle body, and the abutting surface of the limiting block is an inclined surface parallel to the inner side of the headlight body 1.

[0098] In some other embodiments, the X-direction limiting structure 4 includes a strip hole 41 and a limiting rod 42, the Z-direction limiting structure 5 includes a Z-direction positioning hole 51 and a Z-direction locking member 52, and the Y-direction limiting structure 6 includes a plurality of limiting blocks spaced apart in the vertical direction between the sign light body 2 and the headlight body 1.

[0099] Both the strip hole 41 and the Z-direction positioning hole 51 are provided on the upper support cantilever 7; wherein, the strip hole 41 penetrates the upper support cantilever 7 along the Z direction of the vehicle body and extends along the Y direction of the vehicle body; the Z-direction positioning hole 51 penetrates the upper support cantilever 7 along the Z direction of the vehicle body and adopts a circular hole structure.

[0100] The limiting rod 42 and the Z-direction locking member 52 are both connected to the upper side of the mounting plate 3. Each limiting block is fixedly connected to the end face of the marker light body 2 facing the Y direction of the vehicle body. That is, the limiting rod 42, the Z-direction locking member 52 (specifically referring to the locking bolt without the locking nut) and the limiting block will not affect the longitudinal movement of the marker light body 2 relative to the headlight body 1.

[0101] When the upper support cantilever 7 and the mounting plate 3 are connected, specifically when the sign light body 2 is moved from top to bottom, the limiting rod 42 is adapted to be inserted into the strip hole 41, the Z-direction locking member 52 is adapted to be inserted into the Z-direction positioning hole 51 (and the Z-direction locking member 52 is connected to the mounting plate 3 to limit the movement of the upper support cantilever 7 away from the mounting plate 3), and the limiting block is inserted into the gap between the headlight body 1 and the sign light body 2.

[0102] By adopting this technical solution, the loading of the X-direction limiting structure 4, the Z-direction limiting structure 5, and the Y-direction limiting structure 6 can be achieved simultaneously, optimizing the steps in the actual assembly of this device and improving the assembly efficiency of this device.

[0103] In some embodiments, such as Figures 5 to 7 As shown, the lower side of the sign light body 2 has multiple upper protruding ridges 21 that correspond one-to-one with multiple mounting plates 3; each mounting plate 3 has a first lower support cantilever 8 extending toward the sign light body 2 and located on the lower side of the sign light body 2, and this first lower support cantilever 8 has an upper connecting portion 81 that extends upward and connects with the protruding end of the corresponding upper protruding ridge 21.

[0104] When assembling the marker light body 2, firstly, align the multiple upper protruding ridges 21 with the multiple lower mating parts 81 respectively, and then move the marker light body 2 downward to achieve the initial positioning of the marker light body 2 on the XY plane of the vehicle body; subsequently, move downward until the upper protruding ridges 21 connect with the lower mating parts 81, at which point each of the aforementioned limiting blocks abuts against the inner side of the headlight body 1 to achieve the limiting of the marker light body 2 along the Z direction of the vehicle body; at the same time, from the perspective of the overall structure, the first lower support cantilever 8 plays a supporting role for the marker light body 2, preventing the marker light body 2 from sagging under its own weight, and improving the structural strength and stability of the combined structure.

[0105] The reason for using a combination structure of the upper convex ridge 21 and the lower docking part 81, instead of designing the sign light body 2 to directly contact the mounting plate 3 or the first lower support cantilever 8, is that this allows the structure between the sign light body 2 and the first lower support cantilever 8 to be in a cavity, so that when the front of the sign light body 2 hits a pedestrian, the combination of the upper convex ridge 21 and the lower docking part 81 will quickly break apart, thereby reducing the impact and injury.

[0106] In this embodiment, the thickness of the lower docking portion 81 gradually decreases from top to bottom in the horizontal direction; that is, the connection between the lower docking portion 81 and the first lower support cantilever 8 is relatively weak. When the sign light body 2 collides with a person on the front side of the vehicle, the lower docking portion 81 and the first lower support cantilever 8 are prone to breakage, thereby meeting the pedestrian protection collision requirements; at the same time, it avoids the sign light body 2 from breaking and damaging the electronic components inside the sign light body 2, ensuring the structural stability of the sign light body 2 in the event of an accident.

[0107] In some embodiments, such as Figure 8 and Figure 10 As shown, there is a collapsible space between the sign light body 2 and the mounting plate 3; wherein, the collapsible space extends along the X direction of the vehicle body, and the aforementioned upper support cantilever 7 has a reinforcing part 71 on the side facing this collapsible space; unlike the conventional structure, this reinforcing part 71 does not directly contact the mounting plate 3, that is, there is a gap between the reinforcing part 71 and the mounting plate 3, and the side of this reinforcing part 71 facing the mounting plate 3 has an inclined part 711 that slopes from top to bottom away from the mounting plate 3.

[0108] When the sign light body 2 impacts a person, the reaction force causes the sign light body 2 to be squeezed into the rear crumple zone, and the inclined part 711 to contact the mounting plate 3. This reduces the injury to the person caused by the impact, while limiting the trajectory of the sign light body 2 as it squeezes into the crumple zone, preventing excessive squeezing that could damage the sign light body 2, and effectively ensuring the service life of the internal electronic components of the sign light body 2.

[0109] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two mounting plates 3; the two mounting plates 3 are symmetrically distributed, and their symmetry planes are parallel to the XZ plane of the vehicle body and coincide with the midpoint of the vehicle body along the Y direction; that is, the line connecting the midpoint between the two mounting plates 3 and the midpoint of the sign light body 2 is parallel to the X direction of the vehicle body; by adopting this setting, the positioning of both ends of the sign light body 2 is more reliable.

[0110] Specifically, from a practical perspective, adopting the above technical solution will affect the following two process steps:

[0111] Firstly, when connecting the X-direction limiting structure 4, the operator needs to hold and move the marker light body 2 along the XY plane of the vehicle body to align the two strip holes 41 with the two limiting rods 42 respectively. This visual inspection process is simpler and has a lower error rate. When the two limiting rods 42 are inserted into the two strip holes 41 respectively, the two strip holes 41 cooperate with each other to limit the rotation of the marker light body 2 about either limiting rod 42 as an axis.

[0112] Secondly, when connecting the Z-direction limiting structure 5, the operator needs to hold and move the sign light body 2 along the XY plane of the vehicle body so that the two Z-direction positioning holes 51 are respectively aligned with the fixed positions of the two Z-direction locking parts 52; similarly, this visual inspection process is simpler and has a lower error rate. After connecting the support cantilever 7 and the mounting plate 3 through the two Z-direction locking parts 52, the two Z-direction locking parts 52 cooperate with each other to restrict the rotation of the sign light body 2 about any Z-direction locking part 52 as an axis.

[0113] In some embodiments, such as Figure 1 and Figure 6 As shown, the mounting plate 3 also includes a second lower support cantilever 9, which is fixedly mounted on the mounting plate 3. It extends towards the headlight body 1 on the same side and is located below the headlight body 1 on the same side, thus providing support for the headlight body 1. Simultaneously, since the second lower support cantilever 9 connects the headlight body 1 and the mounting plate 3, and the headlight body 1 is fixedly connected to the front frame, the second lower support cantilever 9 also works with the headlight body 1 to reinforce the structure of the mounting plate 3. Specifically:

[0114] In the actual use of the sign light body 2, the reinforcement of the mounting plate 3 structure by the second lower support cantilever 9 is mainly reflected in the process of the sign light body 2 resisting the Y-direction force of the vehicle body. In order to further reflect the substantial effect of this reinforcement, the mounting plate 3 also includes a support part 31. This support part 31 is fixedly installed on the mounting plate 3 and is located on the side of the mounting plate 3 facing the other mounting plate 3, that is, on the adjacent side of the two mounting plates 3.

[0115] Based on this, the sign light body 2 has two alignment portions 22 that are adapted to abut against the two support portions 31 respectively; specifically, by combining the support portion 31 and the alignment portion 22, the alignment portion 22 can abut against the inner side of the support portion 31, restricting the movement of the sign light body 2 toward the Y direction of the vehicle body, thereby enhancing the structural stability between the sign light body 2 and the mounting plate 3.

[0116] Among them, the support part 31 and the mounting plate 3 have an X-direction reserved hole 311 that runs through the X direction of the vehicle body; due to the existence of this X-direction reserved hole 311, the structural strength of the connection between the support part 31 and the mounting plate 3 when resisting the Y-direction force of the vehicle body is reduced, and the connection between the support part 31 and the mounting plate 3 is more likely to break when the sign light body 2 hits a pedestrian, thereby reducing the impact of the impact and meeting the pedestrian protection collision requirements.

[0117] In some embodiments, such as Figure 1 and Figure 6 As shown, the sign light body 2 has two alignment parts 22 that are suitable for abutting against two mounting plates 3 respectively. Specifically, the alignment parts 22 directly abut against the mounting plates 3, which can also achieve the function of accurately positioning the sign light body 2 and supporting the structure of the sign light body 2. However, compared with the method of the alignment parts 22 abutting against the mounting plates 3 through the support parts 31, the insertion of the alignment parts 22 is more difficult. That is, the installation efficiency of this structure will be affected to a certain extent, but it will play a positive role in simplifying the structure and reducing the structural cost.

[0118] In some other embodiments, this application has the following features:

[0119] Firstly, the Z-direction limiting structure 5 includes a Z-direction positioning hole 51 provided on the upper support cantilever 7; this Z-direction positioning hole 51 penetrates the upper support cantilever 7 along the Z direction of the vehicle body, and the inner wall of this Z-direction positioning hole 51 has a reserved fracture opening 511.

[0120] Secondly, each mounting plate 3 has a first lower support cantilever 8 extending toward the sign light body 2 and located below the sign light body 2; and the first lower support cantilever 8 has an upwardly extending (for abutting against the sign light body 2) lower docking portion 81, and the thickness of the lower docking portion 81 gradually decreases from top to bottom in the horizontal direction.

[0121] Third, there is a collapsible space between the sign light body 2 and the mounting plate 3. This collapsible space extends along the X direction of the vehicle body, and the aforementioned upper support cantilever 7 has a reinforcing part 71 on the side facing this collapsible space. Unlike conventional structures, this reinforcing part 71 does not directly contact the mounting plate 3, that is, there is a gap between the reinforcing part 71 and the mounting plate 3, and the side of the reinforcing part 71 facing the mounting plate 3 has an inclined part 711 that slopes from top to bottom away from the mounting plate 3.

[0122] Fourth, the mounting plate 3 also includes a support part 31 fixedly connected thereto, and there is an X-direction reserved hole 311 extending through the X direction of the vehicle body between the support part 31 and the mounting plate 3.

[0123] When the sign light body 2 impacts a person, the reaction force causes the sign light body 2 to be squeezed into the rear crumple zone, and the inclined part 711 to contact the mounting plate 3. At the same time, the trajectory of the sign light body 2 being squeezed into the crumple zone is limited, preventing excessive squeezing that could damage the sign light body 2 and effectively ensuring the service life of the internal electronic components of the sign light body 2. Meanwhile, the Z-direction locking member 52 is squeezed into the reserved fracture opening 511, causing the reserved fracture opening 511 to enlarge and the upper support cantilever 7 to be damaged. Furthermore, disconnections occur between the lower docking part 81 and the first lower support cantilever 8, and between the support part 31 and the mounting plate 3.

[0124] By adopting the above technical solutions, the impact of a collision can be mitigated by sacrificing the vehicle's structural integrity, thereby meeting the requirements for pedestrian protection collisions, reducing the degree of injury to those involved in a collision, and improving the safety of vehicle operation.

[0125] Based on the same inventive concept, this application also provides an automobile, including the positioning and mounting structure proposed in any of the foregoing claims, that is, the positioning and mounting of the two headlight bodies 1 and the marker light body 2 is achieved through this positioning and mounting structure.

[0126] In this embodiment, the initial positioning of the marker light body 2 in the Y direction of the vehicle body is achieved by connecting multiple upper support cantilever arms 7 and multiple mounting plates 3. On this basis, the position of the marker light body 2 in the X and Z directions of the vehicle body is limited by the X-direction limiting structure 4 and the Z-direction limiting structure 5. Furthermore, by finely adjusting the marker light body 2 along the Y direction of the vehicle body and connecting it through the Y-direction limiting structure 6, the complete positioning of the marker light body 2 in the Y direction of the vehicle body can also be achieved.

[0127] Compared with the prior art, the automobile provided in this embodiment has multiple mounting plates 3, and these multiple mounting plates 3 act simultaneously on the positioning of the marker light body 2. Therefore, it can avoid the defect of reduced installation accuracy of the marker light body 2 caused by the excessive deformation of one side of the mounting plate 3. At the same time, when the marker light body 2 is connected to the mounting plate 3, the marker light body 2 can still be finely adjusted along the Y direction of the vehicle body to ensure that the symmetry difference of the gap on both sides of the marker light body 2 can be effectively adjusted. This satisfies the DTS (Displacement Time Synchronization) between the headlight body 1 and the marker light body 2, and between the lamp and the surrounding parts, thereby ensuring the stability of the vehicle structure and driving safety.

[0128] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
