[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0031] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 , a vehicle signal lamp according to an embodiment of the present invention is disclosed, which includes a mounting body 10, a light source board 20 disposed on the front surface of the mounting body 10, a transparent lamp cover 30 covering the light source board 20 and fixed on the front surface of the mounting body 10, and a D-sub connector 40 mounted on the back surface of the mounting body 10.

[0032] An accommodation cavity is formed between the transparent lamp cover 30 and the mounting body 10, and the light source board 20 is disposed in the accommodation cavity.

[0033] A circular sealing groove 12 surrounding the light source board 20 is provided on the front surface of the mounting body 10. A circular protrusion 31 matching the circular sealing groove 12 is provided on the transparent lamp cover 30. The circular sealing groove 12 is filled with a first curing adhesive. When the transparent lamp cover 30 covers the light source board 20, the circular protrusion 31 is received in the circular sealing groove 12 and is sealed after being cured by the first curing adhesive.

[0034] A connection through hole 14 is further provided on the mounting body 10. A mounting seat 16 surrounding the connection through hole 14 is provided on the back surface of the mounting body 10. The D-sub connector 40 is mounted on the mounting seat 16. The D-sub connector 40 is electrically connected to the light source board 20 through the connection through hole 14, and the connection through hole 14 is filled with a second curing adhesive and is sealed after being cured by the second curing adhesive.

[0035] When the transparent lamp cover 30 of the vehicle signal lamp of the present invention covers the light source board 20, the circular protrusion 31 is received in the circular sealing groove 12 and is sealed after being cured by the first curing adhesive. At the same time, the connection through hole 14 is filled with a second curing adhesive and is sealed after being cured by the second curing adhesive. In this way, the sealing performance of the vehicle signal lamp of the present invention is greatly improved, and it can be used in an environment with a water depth of 1 m, thus meeting the use requirements of wading vehicles.

[0036] Preferably, in this embodiment, the D-sub connector 40 includes a wire 42 and a connection head 44 matching the mounting seat 16. A plurality of mounting holes 17 are provided in the peripheral area of the mounting seat 16. A plurality of mounting through holes (not marked in the figure) are provided in the peripheral area of the connection head 44. Screws 46 pass through the mounting through holes and are screwed into the mounting holes 17, thereby fixing the mounting seat 16 and the connection head 44 together.

[0037] In this way, not only is the fixed connection between the aviation plug 40 and the mounting body 10 more stable, but also the sealing performance between the aviation plug 40 and the mounting body 10 is better.

[0038] Combined with the attached drawings, in this embodiment, an annular protrusion 442 matching the connection through-hole 14 is further provided in the central area of the connector 44. When the mounting seat 16 and the connector 44 are fixed together, the annular protrusion 442 is inserted into the connection through-hole 14.

[0039] Specifically, an O-ring seal 444 is also sleeved on the annular protrusion 442.

[0040] It should be noted that the screws involved in the vehicle signal lamp of the present invention are all anti-loosening screws, and the screws are used in combination with gaskets and sealing gaskets.

[0041] The use of anti-loosening screws to achieve the fixed connection of each component in the vehicle signal lamp enables the vehicle signal lamp to meet the impact resistance requirement of 40g.

[0042] Combined with the attached drawings, in this embodiment, the mounting seat 16 is a protrusion, and the vehicle signal lamp further includes a clearance eliminating plate 50 laminated on the back surface of the mounting body 10. A receiving through-hole 52 matching the mounting seat 16 is provided on the clearance eliminating plate 50, and the thickness of the clearance eliminating plate 50 matches the thickness of the mounting seat 16.

[0043] The clearance eliminating plate 50 can eliminate the gap between the vehicle signal lamp and the vehicle body. On the one hand, it can improve the waterproof performance of the vehicle signal lamp on the vehicle body mounting surface. On the other hand, the clearance eliminating plate 50 also has the function of impact buffering and improves the anti-vibration effect during the vehicle's off-road process.

[0044] The clearance eliminating plate 50 is usually made of soft elastic material. Specifically, the clearance eliminating plate 50 can be made of silicone rubber.

[0045] Specifically, in this embodiment, the first curing glue is 907 glue, and the second curing glue is AB glue.

[0046] 907 glue is an external transparent single-component phenolic semi-transparent electronic silicone rubber. Its main function is to increase the connection between the plastic transparent part and the metal rear shell. According to the characteristics of the electronic silicone rubber, its own hardness is 45. It can fill the gap between the plastic transparent part and the metal rear shell, play a role in waterproof sealing, and at the same time has a buffering effect, can resist vibration and impact. The electronic silicone rubber has poor fluidity, and the rear shell can be turned over for screw tightening after assembly. And the glue is in a semi-transparent state, which does not affect the appearance of the lamp itself.

[0047] AB glue is a structural glue for fixing internal wires and strengthening strength. It has excellent fluidity, can fully fill the internal gaps, and becomes a yellow hard glue after solidification, which can play a role in strengthening the structure inside.

[0048] Preferably, in this embodiment, there are at least two light source boards 20. The at least two light source boards 20 are arranged on the installation body 10 at intervals, and the negative electrodes of the at least two light source boards 20 are electrically connected together and then electrically connected to the aviation plug 40.

[0049] The split design in which at least two light source boards 20 are arranged on the installation body 10 at intervals, and the common negative connection of the at least two light source boards 20 makes each module independent and replaceable separately.

[0050] The light source board 20 is arranged on the installation body 10, so that the heat generated by the light source board 20 can be directly conducted to the installation body 10, thereby realizing heat dissipation.

[0051] Preferably, in this embodiment, the light source board 20 is an LED metal substrate, and the installation body 10 is a metal part, thereby improving the heat dissipation effect.

[0052] More preferably, a heat dissipation silicone grease is applied between the light source board 20 and the installation body 10, thereby increasing the contact area between the light source board 20 and the installation body 10, and further improving the heat conduction effect between the light source board 20 and the installation body 10.

[0053] Specifically, in this embodiment, the installation body 10 is a cast aluminum part, and the light source board 20 is an LED aluminum substrate. That is, the light source board 20 includes an aluminum substrate and a plurality of LED light-emitting parts arranged on the aluminum substrate.

[0054] Through the heat dissipation simulation test of the vehicle signal lamp of the present invention, it is obtained that Figure 5 .

[0055] Combined with Figure 5 , under the condition of 30°C, the maximum temperature of the light source board 20: 33.9°C, the maximum temperature rise: 3.9°C. Adding the light source junction temperature of 5 - 10°C / W, the temperature of the light source pad is about 43.9°C, and the ambient temperature for using the chip resistor is 125°C, which meets the requirement of being lower than the 80°C limit.

[0056] That is to say, the vehicle signal lamp of the present invention is positioned as having high reliability and high environmental adaptability, and it can work normally in the environment of -43°C - +70°C.

[0057] Preferably, in this embodiment, the vehicle signal lamp further includes a protective cover 60 that covers the transparent lamp cover 30 and is fixed to the front of the installation body 10.

[0058] Combined with the attached drawings, in this embodiment, the protective cover 60 is a hollow structure.

[0059] It should be noted that the transparent lamp cover 30 in the present invention can be fully transparent or semi-transparent.

[0060] Specifically, in this embodiment, the transparent lamp cover 30 is made of PC9330 material, which has high strength, can meet the requirements of 30g vibration and impact resistance, and can be used in an environment with a low temperature of -33°C.

[0061] Combined Figure 6 with Figure 7 , one side of the transparent lamp cover 30 close to the light source plate 20 includes a first light incident area 301, a second light incident area 302, and a third light incident area 303 arranged in sequence along the length direction of the transparent lamp cover 30. A first protrusion 32 is provided in the first light incident area 301, a second protrusion 33 is provided in the second light incident area 302, and a third protrusion 34 is provided in the third light incident area 303. The first protrusion 32, the second protrusion 33, and the third protrusion 34 are all transparent triangular pyramid shapes.

[0062] Among them, the side surface of the first protrusion 32 is a square with a missing corner, and the bottom surface of the groove surrounded by the three first protrusions 32 is an equilateral triangle. Specifically, the missing corner sides of the side surfaces of the three first protrusions 32 are the sides of the equilateral triangle on the bottom surface of the groove.

[0063] Among them, the side surface of the second protrusion 33 is a triangle, and the bottom surface of the groove surrounded by the three second protrusions 33 is an equilateral triangle. Specifically, the bottom sides of the side surfaces of the three second protrusions 33 are the sides of the equilateral triangle on the bottom surface of the groove.

[0064] Among them, the side surface of the third protrusion 34 is a square with a missing corner, and the bottom surface of the groove surrounded by the three third protrusions 34 is an equilateral triangle. Specifically, the missing corner sides of the side surfaces of the three third protrusions 34 are the sides of the equilateral triangle on the bottom surface of the groove.

[0065] The first protrusion 32 can refract the emitted light inside and then scatter it out, increasing the left and right emission angles to 180°, the upper emission angle to 150 degrees, and the lower emission angle to 90 degrees, expanding the light emission range, enabling pedestrians or drivers to see the light signal to the greatest extent; the second protrusion 33 can concentrate the internally refracted light, with a light emission angle of 60 degrees, increasing the light intensity in the central area, enabling pedestrians or drivers to see the light signal at the farthest distance of about 200 meters directly behind; the third protrusion 34 can refract the emitted light inside and then concentrate it out, increasing the left and right emission angles to 180°, the upper emission angle to 90 degrees; the lower emission angle is 60 degrees. The upper emission angle of 90 degrees can supplement the light to increase the light intensity in the central area 424, and the lower emission angle of 60 degrees can constrain the light pattern, avoiding irradiating the ground and causing light loss, enabling pedestrians or drivers to see the light signal to the greatest extent.

[0066] In summary, the above structural settings of the first protrusion 32, the second protrusion 33, and the third protrusion 34 can greatly improve the light emission uniformity and light emission range of vehicle signal lights.

[0067] Specifically, in this embodiment, the shapes, sizes, and arrangement manners of the first protrusion 32, the second protrusion, and the third protrusion 34 are exactly the same.

[0068] Preferably, in this embodiment, a partition strip 3021 extending along the width direction of the transparent lamp cover 30 is further provided in the second light incident area 302. A plurality of fourth protrusions 35 spaced along the width direction of the transparent lamp cover 30 are provided in the partition strip 3021. The fourth protrusions 35 are transparent quadrangular pyramid shapes.

[0069] Combined with Figure 4 , the partition strip 3021 divides the second light incident area 302 into two areas.

[0070] The setting of the partition strip 3021 can cut off light, making the angle of the strongest light intensity line shine upward, preventing light from affecting the driver of the vehicle behind. The function of the transparent quadrangular pyramid-shaped fourth protrusion 35 is to collect the cut-off line light and re-diverge the refracted light in the internal irregular directions.

[0071] Specifically, the ratio of the size of the fourth protrusion 35, the width of the partition strip 3021, and the size of the second protrusion 33 is 1:1.2 - 1.8:2.4 - 6.

[0072] With such a size setting, only one fourth protrusion 35 can be arranged in the partition strip 3021 in its width direction.

[0073] Preferably, in this embodiment, the surface of the transparent lamp cover 30 close to the light source plate 20, the surface of the transparent lamp cover 30 far from the light source plate 20, and the light source plate 20 are parallel to each other.

[0074] Combined with the attached drawings, in this embodiment, the transparent lamp cover 30 further includes a plurality of mounting parts 36. Mounting grooves 362 are provided on the mounting parts 36. An embedded nut (not shown in the figure) is fixed in the mounting grooves 362. A screw (not shown in the figure) passes through the mounting body 10 and the light source plate 20 in sequence and then is screwed into the embedded nut, thereby fixing the mounting body 10, the light source plate 20, and the transparent lamp cover 30 together.

[0075] An embedded nut is fixed in the mounting groove 362 of the transparent lamp cover 30, so that the transparent lamp cover 30 can be directly fixed on the mounting body 10 without other auxiliary parts to fix the transparent part, which can reduce the overall thickness of the lamp.

[0076] Furthermore, during the assembly process of the transparent lamp cover 30, the bottom end of the embedded nut contacts the light source plate 20, so as to offset and buffer the force on the transparent lamp cover 30, greatly enhancing the structural strength of the vehicle signal lamp. At the same time, the bottom end of the embedded nut is in contact with the front surface of the light source plate 20, and can also play a role in heat conduction.

[0077] In addition, the embedded nut also has the functions of anti - detachment and anti - rotation, which can increase the overall connection strength.

[0078] Specifically, in this embodiment, the transparent lamp cover 30 and the embedded nut are integrally formed.

[0079] Specifically, in this embodiment, the transparent lamp cover 30 is in the shape of a cuboid, and there are four mounting parts 36, and the four mounting parts 36 are respectively located at the four corners of the transparent lamp cover 30.
