[0037] In the claims, specification and the above drawings of the utility model, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is to say, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements.

[0038] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0039] Please also read Figures 2 to 6 Now, the positioning light module 1 provided by the utility model is described. The positioning light module 1 includes a lampshade 10, a circuit board 20 and a sealing layer 30; the lampshade 10 has a accommodating space 101 opening to the rear; there are multiple circuit boards 20, and the multiple circuit boards 20 are arranged in the accommodating space 101 along the front-to-back direction, and a light source is provided on the circuit board 20 located at the front end, and different circuit boards 20 are conductively connected; the sealing layer 30 is sealed at the rear opening 102 of the lampshade 10, and the external power line 40 passes through the sealing layer 30 and is conductively connected to the circuit board 20 located at the rear end, thereby realizing the electrical connection between the positioning light module 1 and the external component (such as a driving computer or an external power supply); in addition, at least the front side of the circuit board 20 located at the front end of the lampshade 10 is transparent to meet the demand of emitting light forward.

[0040] In this embodiment, the conductive connection between the two circuit boards 20 can be achieved through conductive components such as pins and wires. The same conductive component can achieve a conductive connection between two adjacent circuit boards 20, and can also achieve a conductive connection between non-adjacent circuit boards 20.

[0041] In this embodiment, the number of circuit boards 20 is at least two (for example, two, three, four, six). Except for the circuit board 20 used for emitting light at the front end, the number of the remaining circuit boards 20 is set according to the specific light source setting method and the light emission requirements. This embodiment exemplarily shows the design scheme of setting two front and rear circuit boards 20. In addition, the size and shape of each circuit board 20 are set according to the circumferential contour of the lampshade 10, and the layout of the light source on the front circuit board 20 is set according to the light emission requirements, which are not listed here one by one. In this embodiment, the implementation method of the light source includes but is not limited to LED point light sources.

[0042] In this embodiment, the board spacing between two adjacent circuit boards 20 is 6mm to 12mm (for example, 7mm, 8mm, 9mm, 10mm, 11mm). The board spacing is reasonably controlled to optimize the front and rear stacking dimensions while avoiding interference between electrical components of different circuit boards 20.

[0043] Compared with the prior art, the positioning light output module 1 provided in this embodiment is designed to have a multi-layer circuit board structure used for light emission, that is, multiple circuit boards 20 are arranged along the front-to-back direction, and light emission is achieved through the light source arranged on the frontmost circuit board 20, and the current is adjusted through the remaining circuit boards 20 so that the light source can emit light normally. Compared with the traditional one-piece circuit board 20 design, this embodiment is changed to a three-dimensional stacking design in the front-to-back direction, which effectively reduces the overall size of the circuit board structure (the structure composed of all circuit boards 20) in the direction perpendicular to the front-to-back direction. The positioning light output module 1 of this embodiment effectively realizes the miniaturization design of the positioning light output module 1 while meeting the normal light emission performance.

[0044] In some embodiments, the sealing layer 30 is a heat-conducting sealing layer, and the sealing layer 30 is in heat-conducting contact with the circuit board 20 located at the rear end. Since the functions of different circuit boards 20 are differentiated, the circuit board 20 at the front end realizes light emission, and the remaining circuit boards 20 realize the power adjustment function, so the heat generation of the circuit board 20 at the rear end is more serious. The circuit board 20 at the rear end can be set as the circuit board 20 with the most serious heat generation, which needs to be dissipated the most. By absorbing the heat of the circuit board 20 by the heat-conducting sealing layer 30, the heat dissipation requirements of the circuit board 20 can be effectively guaranteed. Taking the scheme with two layers of circuit boards 20 shown in the figure as an example, the circuit board 20 on the front side is mainly used for light emission, and the circuit board 20 on the rear side needs to connect the light source of the front circuit board 20 and the power supply module in the vehicle body to realize the driving of the light source. Therefore, the circuit board 20 at the rear end generates a large amount of heat, and it realizes heat dissipation through heat-conducting contact with the heat-conducting sealing layer.

[0045] In this embodiment, the sealing layer 30 is composed of a heat-conducting adhesive, which is a single-component, heat-conducting, room-temperature curing organic silicon adhesive sealant. It undergoes a condensation reaction with water in the air to release low molecules to cause cross-linking and curing, and is vulcanized into a high-performance elastomer. It has excellent resistance to cold and hot alternation, aging resistance and electrical insulation performance, as well as excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical medium resistance. It does not swell and has good adhesion to most metal and non-metal materials, and is suitable for sealing electronic devices. A glue-filling space is formed between the rear side of the rear circuit board 20 and the rear side opening 102 of the lampshade 10. The sealing layer 30 can be directly poured into the glue-filling space after the circuit board 20 and the lampshade 10 are assembled. After the heat-conducting adhesive is cured and formed, the sealing layer 30 is formed. While achieving sealing, the sealing layer 30 can also achieve effective contact with the circuit board 20 and achieve a fixed connection between the rear circuit board 20 and the lampshade 10.

[0046] In this embodiment, the thermal contact between the sealing layer 30 and the circuit board 20 can be achieved by direct surface contact between the sealing layer 30 and the circuit board 20, or by bonding the sealing layer 30 and the circuit board 20 with a thermally conductive adhesive, or by indirect contact between the sealing layer 30 and the circuit board 20 via a thermally conductive contact layer (such as an aluminum alloy sheet layer).

[0047] In this embodiment, the heat dissipation function of the sealing layer 30 can be achieved in the following ways: 1) the rear side of the sealing layer 30 is directly in contact with the air to achieve heat dissipation; 2) a heat dissipation component (such as aluminum heat dissipation fins) is provided on the rear side of the sealing layer 30, and heat dissipation is achieved by contacting the heat dissipation component with the air. For way 2), a plug-in column can be provided on the front side of the heat dissipation fin, and the plug-in column is embedded in the sealing layer 30, and the heat dissipation component and the sealing layer 30 are fixedly connected as the sealing layer 30 solidifies.

[0048] In some embodiments, see Figure 2 , Figure 5 and Figure 6 The two adjacent circuit boards 20 are conductively connected through the conductive pins 50 to achieve a conductive connection between the two adjacent circuit boards 20. At the same time, since the conductive pins 50 themselves have a certain structural strength, they can also provide a certain support between the two circuit boards 20, maintain the overall structural stability of the circuit board structure, and avoid the collapse of the stacked multiple circuit boards 20.

[0049] In the embodiment where the conductive pin 50 is provided, in order to enhance the heat dissipation effect on the front circuit board 20, the conductive pin 50 is a heat-conductive and electrically conductive component, and the rear end of the conductive pin 50 is thermally connected to the thermally conductive sealing layer. The heat generated by the front circuit board 20 can be transferred backward to the thermally conductive sealing layer through the rear circuit board 20, and the heat dissipation is achieved through the heat exchange between the thermally conductive sealing layer and the outside air.

[0050] In other embodiments, in order to enhance the heat dissipation effect of the front circuit board 20, except for the circuit board 20 located at the rear end, the rear side of at least one circuit board 20 of the remaining circuit boards 20 is bonded and connected to a heat-conducting layer (such as an aluminum alloy heat-conducting sheet, a heat-conducting silicone layer), and the heat-conducting layer can absorb the heat generated by the corresponding circuit board 20; a heat-conducting groove extending in the front-to-back direction is provided on the side wall of the lampshade 10, and a strip-shaped heat-conducting member (such as an aluminum alloy heat-conducting strip or a heat-conducting silicone filled in the heat-conducting groove) is filled in the heat-conducting groove. The heat-conducting member connects the heat-conducting layer and the heat-conducting sealing layer, and then transfers the heat of the heat-conducting layer to the heat-conducting sealing layer. At the same time, the setting of the heat-conducting groove can also prevent the heat-conducting member from protruding from the side wall of the lampshade 10, thereby effectively avoiding the heat-conducting member from affecting the assembly of the circuit board 20. It should be noted that in order to avoid affecting the normal operation of the front circuit board 20, the heat-conducting layer is an insulating layer.

[0051] Based on the embodiment provided with the conductive pin 50, see Figure 5 and Figure 6 , the conductive pin 50 is connected between two adjacent circuit boards 20, and the two adjacent circuit boards 20 are provided with sockets 201 respectively; the front and rear ends of the conductive pin 50 form step structures 510 respectively, the step structures 510 are plugged into the corresponding sockets 201, and the step surfaces 511 of the step structures 510 abut against the board surfaces of the corresponding circuit boards 20 to limit the spacing between the two adjacent circuit boards 20. By rationally arranging the arrangement sequence of the circuit boards 20 in the front-to-back direction, the conductive connection between the two circuit boards 20 can be achieved without making the conductive pin 50 cross the middle circuit board 20. The arrangement of the conductive pin 50 is simpler, and the crossing design is avoided from occupying the limited space on the circuit board 20; while realizing the connection and conduction with the circuit board 20 through the step structure 510, the displacement of the circuit board 20 and the pin is effectively limited, and the reliability of the conductive pin 50 supporting between the two circuit boards 20 is further improved.

[0052] In some embodiments, see Figure 2 , Figures 5 to 9 , the side wall of the accommodating space 101 is provided with a positioning convex rail 60 extending in the front-to-back direction, and the outer peripheral surface of the circuit board 20 is provided with a positioning notch 202 corresponding to the positioning convex rail 60, and the positioning notch 202 cooperates with the positioning convex rail 60 to limit the displacement of the circuit board 20 in the circumferential direction of the circuit board 20. During assembly, the circuit board 20 is pushed forward from the rear opening 102 of the lampshade 10, and the positioning notch 202 is aligned with the positioning convex rail 60. When the circuit board 20 is pushed into the lampshade 10, the positioning convex rail 60 also enters the positioning notch 202 and begins to limit the circumferential movement of the circuit board 20, so as to avoid the problem that the circuit board 20 rotates in its own circumferential direction and affects the conductive connection between the two circuit boards 20. It should be noted that in order to avoid the problem of cracking of the circuit board 20 under stress, the positioning notch 202 and the positioning convex rail 60 are clearance-matched to avoid the generation of extrusion stress at the positioning notch 202.

[0053] More specifically, in order to improve the uniformity of the circumferential force on the circuit board 20, a plurality of positioning convex rails 60 are provided along the circumference of the accommodating space 101, and a plurality of positioning notches 202 are provided correspondingly on the edge of the circuit board 20. Based on this, the cross-sectional shapes of different positioning convex rails 60 can also be designed differently, and the shapes of different positioning notches 202 can be provided differently, thereby achieving a foolproof effect of installing the circuit board 20; for example, two positioning convex rails 60 are provided, one of which has a semicircular cross-section and the other has a rectangular cross-section, and the two positioning notches 202 are provided in accordance with the shape.

[0054] Based on the above embodiments, see Figure 2 , Figures 5 to 9The rear end of the positioning convex rail 60 is provided with an introduction slope 601. In the direction from front to back, the introduction slope 601 is inclined in a direction away from the central axis of the accommodating space 101. When the circuit board 20 is pushed in, the introduction slope 601 can guide the circuit board 20, making it convenient for the positioning notch 202 to align with the positioning convex rail 60.

[0055] In some embodiments, see Figure 5 and Figure 7 The accommodating space 101 is provided with a plurality of positioning protrusions 60 along its circumference, wherein at least one positioning protrusion 60 is provided with a first limiting protrusion 70, and the first limiting protrusion 70 abuts against the front side surface of the corresponding circuit board 20 to limit the forward displacement of the circuit board 20, so as to prevent the circuit board 20 from being pushed in too deep, affecting the assembly with other circuit boards 20, or affecting the light emission.

[0056] Specific implementation examples are as follows: 1) A first limiting protrusion 70 (such as Figure 5 and Figure 7 1) As shown in the figure, the positioning convex rail 60 only limits the front and rear positions of the circuit board 20 at the front end, and the limiting of the remaining circuit boards 20 can be achieved by other structures provided on the lampshade 10, or by the supporting structure between the circuit boards 20. 2) A plurality of first limiting protrusions 70 distributed along the front and rear directions and in a stepped shape are provided on the same positioning convex rail 60, and different circuit boards 20 are limited by different first limiting protrusions 70; in this manner, the protrusion height of the first limiting protrusion 70 toward the central axis of the accommodating space 101 gradually decreases from front to back, and the corresponding depths of the positioning notches 202 on different circuit boards 20 also gradually decrease from front to back, and the limiting function is satisfied without affecting the pushing-in of the circuit board 20 (for example, the circuit board 20 at the front end needs to slide over several first limiting protrusions 70 on the rear side before it can abut against the front and rear of the first limiting protrusion 70 at the front end).

[0057] In some embodiments, see Figure 5 and Figure 7 A second limiting protrusion 80 is provided on the side wall of the accommodating space 101, and the second limiting protrusion 80 abuts against the front side surface of the corresponding circuit board 20 to limit the forward displacement of the circuit board 20 to prevent the circuit board 20 from being pushed in too deep, affecting the assembly with other circuit boards 20, or affecting the light emission.

[0058] It should be noted that the scheme of setting the first limiting protrusion 70 and the scheme of setting the second limiting protrusion 80 can be used separately or in combination. This embodiment exemplarily shows a case of using the two in combination, specifically: the front end circuit board 20 is limited by the first limiting protrusion 70, and the rear end circuit board 20 is limited by the second limiting protrusion 80.

[0059] Based on the same inventive concept, the present application embodiment further provides a clearance lamp assembly, see Figure 1 and Figure 2 The position lamp assembly includes the above-mentioned position lamp light output module 1, and also includes a decorative shell 2 and a mounting base 3 arranged at the bottom of the decorative shell 2; a mounting opening 21 is opened on the front side of the decorative shell 2, and the lampshade 10 is inserted into the mounting opening 21, and the mounting base 3 is connected to the vehicle body.

[0060] In this embodiment, the mounting base 3 and the vehicle body are connected by means of buckles and threaded connectors. Of course, the connection can also be achieved by other connection methods, which are not listed here one by one.

[0061] Compared with the prior art, the position marker light assembly provided in the present embodiment effectively reduces the size of the position marker light output module 1 in a direction perpendicular to the front-to-back direction by adopting the above-mentioned position marker light output module 1, thereby reducing the size of the decorative shell 2 in a direction perpendicular to the front-to-back direction; and, by reasonably controlling the spacing between adjacent circuit boards 20, the space occupied by the entire circuit board structure in the front-to-back direction will not be excessively increased, that is, the size of the position marker light output module 1 in the front-to-back direction will not be excessively increased, thereby fully utilizing the front-to-back longitudinal depth space inside the decorative shell 2 to meet the installation requirements of the position marker light output module 1, and ultimately achieving a miniaturized design of the overall size of the position marker light assembly.

[0062] In some embodiments, see Figure 1 and Figure 2 In order to improve the sealing performance of the lampshade 10 and the decorative housing 2 and prevent water or other pollutants from entering, a sealing ring 4 is provided between the lampshade 10 and the installation opening 21 .

[0063] In some more specific embodiments, see Figure 2 The lampshade 10 includes a light emitting cover body 110 and a mounting cover body 120 disposed on the rear side of the light emitting cover body 110. The mounting cover body 120 is cylindrical and opaque, and a plurality of circuit boards 20 are mounted inside the mounting cover body 120. The light emitting cover body 110 is buckled at the front end of the mounting cover body 120. The light emitting cover body 110 is a light-transmitting component. An optical texture is provided on the light incident surface of the light emitting cover body 110 and / or an optical texture is provided on the light emitting surface to perform effects such as uniform light and diffusion on the light emitted by the light source. The mounting cover body 120 is inserted into the mounting opening 21, and a front mounting limiter 130 is provided on the outer periphery of the front end of the mounting cover body 120. The sealing ring 4 is sleeved on the outer periphery of the mounting cover body 120 and abuts against the rear side of the front mounting limiter 130. The sealing ring 4 is tightly abutted between the mounting cover body 120 and the side wall of the mounting opening 21 to achieve sealing. In this embodiment, the light emitting cover body 110 can be a curved cover body (such as Figure 2As shown in the figure), or a flat cover (not shown in the figure), is selectively set according to actual light output requirements.

[0064] In specific implementation, the front side installation limiter 130 is a continuously arranged annular component, which ensures that the sealing ring 4 is evenly stressed in its own circumferential direction and improves the reliability of the seal. At the same time, the front side surface of the front side installation limiter 130 is continuously arranged, which is also conducive to ensuring the aesthetic appearance.

[0065] For more details, see Figure 2 The outer peripheral surface of the mounting cover 120 is also provided with a rear mounting limit piece 140, and the rear mounting limit piece 140 is located behind the front mounting limit piece 130, and a receiving groove 41 for receiving the sealing ring 4 is formed between the two to limit the displacement of the sealing ring 4 in the front-to-back direction to prevent the sealing ring 4 from falling off from the mounting cover 120 during the loading and unloading process and the use process.

[0066] In some specific embodiments of the sealing ring 4, see Figure 2 A sealing groove is formed on the outer periphery of the sealing ring 4, which is clamped with the side wall panel of the installation opening, and a sealing guide surface 42 is formed on the rear end of the sealing ring 4; on this basis, a avoidance ring groove 121 is opened in the area adjacent to the front side installation limit member 130 on the light output cover body 110, and the avoidance ring groove 121 is located on the rear side of the front side installation limit member 130. During installation, the sealing ring 4 is first sleeved on the installation cover 120 to form an integral structure, and then the integral structure is inserted into the installation opening 21. During the insertion process, the installation opening 21 squeezes the sealing guide surface 42, and finally enters the sealing groove under the guidance of the sealing guide surface 42. Since the front wall surface of the sealing groove abuts against the front end surface of the installation opening, and the rear wall surface abuts against the rear end surface of the installation opening, the abutment causes the front corner of the sealing ring 4 to deform, squeezing the installation cover 120 inward. In order to avoid excessive stress on the sealing ring 4, a avoidance ring groove 121 corresponding to the front corner area of ​​the sealing ring 4 is provided to adapt to this deformation, so that the stress caused by the deformation of the sealing ring 4 is released to a certain extent.

[0067] On the basis of the above-mentioned embodiment, in order to further enhance the reliability of the limit positioning between the sealing ring 4 and the mounting cover body 120 on the radial surface of the mounting cover body 120, a step groove 43 is provided on the front end surface of the sealing ring 4, and the step groove 43 is engaged with the front side mounting limit piece 130, which can not only limit the displacement of the sealing ring 4 in the front-to-back direction, but also limit the displacement of the sealing ring 4 in the direction perpendicular to the front-to-back direction (i.e., on the radial surface of the mounting cover body 120), thereby enhancing the limit reliability.

[0068] An example of a specific configuration of the present application is as follows: the circuit board 20 is provided with two front and rear ones, the lampshade 10 and the circuit board 20 on the rear side are glued to form a sealing layer 30, the lampshade 10 and the sealing ring 4 are snap-connected, and the decorative shell 2 and the mounting base 3 are screwed. The light source is an LED point light source, which is 5mm to 8mm (for example, 6mm, 7mm) away from the optical surface (i.e., the rear side of the light-emitting cover body 110), the required luminous flux is 6lm, and the current is 50mA; the area of ​​the circuit board 20 on the front side is 200mm 2 , diameter 16mm, the area of ​​the circuit board 20 on the rear side is 254mm 2 , with a diameter of 18mm, the heat dissipation area is reduced, the internal space size is optimized, and the overall size of the marker light assembly is reduced.

[0069] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, comprising the above-mentioned position marker light assembly.

[0070] Compared with the prior art, the vehicle provided in this embodiment realizes a miniaturized design of the position marker lights by adopting the above-mentioned position marker light assembly, which is beneficial to reducing driving wind resistance and improving aesthetics.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
