Description
Technical Field
[0001] This application relates to the field of vehicle lighting equipment, and in particular to a driving light. Background Technology
[0002] As a crucial component of vehicle lighting equipment, driving lights have become increasingly important in recent years due to the diversification of vehicle operating environments. They not only need to meet basic lighting requirements but also possess enhanced waterproofing capabilities to withstand complex conditions. This is especially true when mounted at an angle on the roof, where waterproofing design is paramount. To ensure reliable operation in harsh environments, the industry has continuously raised its waterproofing standards, placing even stricter demands on driving light design. Current driving lights are typically mounted on the roof using mounting brackets. To address waterproofing, vents are located at the bottom of the lamp body, allowing water to drain naturally under gravity. A sealant groove is located at the front of the lamp body, where the lamp plate is installed and sealed with sealant. This design, which prevents water from entering the lamp body at the front and drains water at the rear, achieves the waterproofing function. While existing driving lights alleviate waterproofing issues to some extent, several shortcomings remain. The drainage system in current driving lights is less effective when mounted at an angle, allowing water to easily seep into the lamp body through the vents, potentially damaging electrical components. Meanwhile, the difficulty in controlling the amount of adhesive applied during the glue tank process has long been a problem. Too little adhesive leads to seal failure, while too much causes overflow, affecting appearance quality and increasing material waste. This is especially true in mid-to-high-end vehicles, where consumers have high demands for the overall appearance and precision of the driving lights. Furthermore, in special scenarios such as engineering vehicles and off-road vehicles, the vehicles experience bumps and other complex conditions on uneven roads. The vents of the tilted driving lights are prone to water backflow into the lamp body due to angle changes, potentially causing electrical malfunctions. The vents may also be damaged by significant bumps, reducing the lifespan of the driving lights. These problems directly affect the waterproof performance and production efficiency of driving lights, necessitating a superior structural design to address these shortcomings. Utility Model Content
[0003] In order to improve the waterproof performance and production efficiency of driving lights, effectively prevent backflow from the drainage holes of driving lights and overflow of glue during glue injection, and extend the service life of driving lights, this application provides a driving light.
[0004] A driving light includes a lamp body and a light assembly for illumination. The lamp body has a receiving cavity, and the light assembly is disposed within the receiving cavity. The light assembly includes a lamp panel and a light element. The lamp body is disposed within the lamp body. A glue groove is provided on the front surface of the lamp body, and an anti-overflow protrusion is provided within the glue groove. The lamp panel is mounted on the front surface of the lamp body, and the inner surface of the lamp panel abuts against the anti-overflow protrusion. A protective partition and a vent hole are provided on the back of the lamp body. The protective partition forms an isolation cavity, and the vent hole is located within the isolation cavity. The protective partition has a drainage channel that communicates with the isolation cavity and is located below the vent hole and extends downward along the protective partition. By adopting the above technical solution, the anti-overflow protrusion is added to the glue groove on the front surface of the lamp body. This design can effectively control the glue filling range, prevent glue from overflowing due to excessive glue during the glue application process, thereby improving the sealing effect and ensuring the overall appearance quality of the driving light. During installation, the inner surface of the light panel abuts against the anti-overflow protrusion, further ensuring a tight fit between the light panel and the light body, enhancing the front waterproof performance. Simultaneously, the protective partition on the back of the light body forms an isolation cavity, protecting the vent within this cavity. This not only strengthens the light body structure and prevents damage to the vent, but also reduces the direct entry of external moisture into the light body, protecting internal electrical components from moisture. Furthermore, the drainage channel on the protective partition, located below the vent and extending downwards along the partition, guides accumulated water out in an orderly manner, effectively preventing backflow caused by bumps or tilted installation. This significantly improves the waterproof capability and lifespan of the driving light under complex operating conditions. This structural design optimizes the waterproof performance of the driving light in multiple ways, meeting the needs of vehicles in diverse usage environments. Preferably, the side of the protective partition near the vent is an arc surface. By adopting the above technical solution, the side of the protective partition near the vent is made into an arc surface, which effectively guides the water accumulated in the isolation chamber to slide down along the arc surface, preventing water from directly impacting the vent when the vehicle is bumpy, thus preventing moisture from entering the lamp body. Simultaneously, the arc surface design reduces the probability of water stagnation at the edge of the protective partition, further reducing the risk of moisture seeping into the vent through capillary action. Furthermore, compared to flat or sharp transition structures, the arc surface structure reduces stress concentration during manufacturing, improving the structural strength of the protective partition and thus enhancing the durability of the driving light under complex operating conditions. This design not only improves the waterproof performance of the driving light but also optimizes the overall structural reliability and service life. Preferably, the height of the protective partition is greater than the height of the vent. By adopting the above technical solution, the height of the protective partition being greater than the height of the vent effectively prevents liquid from entering the lamp body through the vent. Specifically, when the driving light is bumpy or installed at an angle, liquid will flow along the lamp body surface due to gravity.Because the protective baffle is higher than the vent, liquid is blocked from directly reaching the vent during flow, thus preventing liquid from seeping into the lamp body through the vent. Furthermore, this design reduces the possibility of external dust or impurities entering the lamp body through the vent, further improving the sealing performance and reliability of the driving light. Preferably, the bottom of the lamp body is provided with at least one set of water-guiding components, each including several spaced-apart protrusions arranged in parallel, forming a water-guiding channel between the protrusions, with openings on both sides of the channel. By adopting the above technical solution, the water-guiding components at the bottom of the lamp body can effectively guide water flow out, preventing water accumulation from damaging the driving light. Specifically, the water-guiding channel formed between the several parallel protrusions utilizes the natural flow characteristics of water, allowing accumulated water to drain smoothly along the water-guiding channel from the openings on both sides. This structure not only prevents water accumulation at the bottom of the lamp body but also reduces the risk of component damage caused by water flow impact. Furthermore, the special layout of the water-guiding channel can adapt to the complex drainage needs of vehicles under bumpy road conditions, thereby significantly improving the waterproof performance and service life of the driving light. Preferably, the outlet of the drainage channel faces the opening of the water-guiding channel. By adopting the above technical solution, with the outlet of the drainage channel facing the opening of the water-guiding channel, water flowing into the isolation chamber from the vent hole can be effectively guided to flow in a specific direction along the drainage channel set in the protective partition, and finally introduced into the bottom of the lamp body through the opening of the water-guiding channel and flowed away. Since there are openings on both sides of the water-guiding channel, this design ensures that water can be smoothly guided out no matter which direction it enters, avoiding water accumulation in the lamp body. At the same time, the cooperative design of the drainage channel and the water-guiding channel makes full use of the internal space of the lamp body, reduces the occupation of additional structures, and improves the compactness of the overall structure. This design is particularly suitable for driving lights installed at an angle. When the vehicle is bumpy or the angle changes, it can effectively prevent water from flowing back into the lamp body, thereby protecting the electrical components inside the lamp body from damage and significantly improving the waterproof performance and service life of the driving light. Preferably, the length of the water-guiding channel gradually shortens from the edge of the lamp body to the middle of the lamp body. By adopting the above technical solution, the design of the water guiding channel gradually shortening from the edge to the middle of the lamp body is more reasonable, effectively guiding water flow towards the edge of the lamp body for drainage. Because the water guiding channel in the middle of the lamp body is shorter and the one at the edge is longer, this gradual structural design allows water to more easily converge along the longer channel to the edge of the lamp body under the influence of gravity, thus preventing water from stagnating in the middle. At the same time, this design also reduces backflow caused by bumps, further reducing the risk of water flowing back into the lamp body. Therefore, this structure not only improves the drainage efficiency of the driving light but also enhances its waterproof performance under complex working conditions, ensuring the safe operation of the internal electrical components of the driving light.Preferably, the height of the anti-overflow protrusion is less than or equal to the height of the glue groove. By adopting the above technical solution, the height of the anti-overflow protrusion is designed to be less than or equal to the height of the glue groove, which can effectively control the overflow range of the glue during the glue application process. Specifically, when the glue is filled into the glue groove, the anti-overflow protrusion can limit the glue from spreading to the outside of the glue groove, preventing the glue from overflowing from the edge of the glue groove when the lamp panel is pressed, thus affecting the appearance quality of the lamp body. At the same time, this height design ensures that the amount of glue filled in the glue groove is moderate, neither too little glue will lead to a decrease in sealing performance, nor too much glue will cause waste or contamination of the lamp body surface. Therefore, this design not only improves the sealing reliability between the lamp panel and the lamp body, but also optimizes the process controllability during production, thereby improving the overall waterproof performance and manufacturing efficiency of the driving lamp. Preferably, the number of anti-overflow protrusions is four, and the four anti-overflow protrusions are evenly distributed. By adopting the above technical solution, the number of anti-overflow protrusions is set to four, and they are evenly distributed in the glue groove. This design can ensure a more uniform distribution of the glue in the glue groove when the lamp panel and the front surface of the lamp body are sealed and assembled. Specifically, the four anti-overflow protrusions provide multi-point support for the lamp panel, preventing uneven stress during installation from causing localized accumulation or overflow of adhesive. Furthermore, the multi-point support structure enhances the connection stability between the lamp panel and the lamp body, further improving the overall waterproof performance and assembly quality of the driving light. Preferably, the spacing of the drainage channels ranges from 0.5cm to 2cm. By adopting the above technical solution, setting the spacing of the drainage channels within the range of 0.5cm to 2cm effectively balances drainage efficiency and structural strength. On the one hand, drainage channels within this spacing range ensure smooth water flow, preventing water accumulation inside the lamp body and reducing the risk of leakage due to water pressure changes; on the other hand, a reasonable spacing design also ensures the structural stability of the protective partition, preventing insufficient material strength due to too small a spacing or affecting drainage effect due to too large a spacing. Within this range, the drainage channels can meet the drainage needs at different tilt angles and adapt to the bumps that may be encountered during vehicle operation, further improving the waterproof performance and service life of the driving light. Preferably, the lamp body further includes a mounting bracket for fixing the driving lamp to the vehicle roof, and the mounting bracket is rotatably connected to the lamp body. By adopting the above technical solution, the rotatable connection design between the mounting bracket and the lamp body can effectively adapt to the bumpy conditions of the vehicle under complex road conditions. When a vehicle travels on uneven roads, the driving lamp may be subjected to impacts and vibrations from different directions. Existing fixed connection methods can easily lead to damage to the internal structure of the lamp body or a decrease in sealing performance. However, through the rotatable connection, the mounting bracket can rotate and adjust to a certain extent with the vehicle's bumps, thereby mitigating the impact of external impacts on the lamp body and improving the overall stability of the driving lamp.Meanwhile, the drainage design of this application ensures that the tilted driving lights maintain good drainage performance at different angles, preventing water from flowing back into the lamp body due to angle changes, further enhancing the waterproof reliability of the driving lights and extending their service life.
[0005] In summary, this application includes at least one of the following beneficial technical effects:
[0006] 1. After installing anti-overflow protrusions in the glue groove on the front surface of the lamp body, the height of the anti-overflow protrusions is less than or equal to the height of the glue groove, which can effectively block the glue. When the glue is injected into the glue groove, the anti-overflow protrusions can limit the flow range of the glue, prevent the glue from overflowing due to overfilling, and ensure that the glue is evenly distributed in the glue groove, thereby improving the sealing reliability between the lamp panel and the lamp body and improving the overall appearance quality of the driving light;
[0007] 2. The protective partition and the vent holes work together to form an isolation chamber, with the vent holes located inside the isolation chamber. The protective partition effectively blocks external water flow from directly impacting the vent holes. Furthermore, by incorporating a drainage channel located below the vent holes on the protective partition, extending downwards along the partition, even if a small amount of moisture enters the isolation chamber, it will be discharged along the drainage channel due to gravity. This effectively prevents water from flowing back into the lamp body, significantly improving the waterproof performance of the driving lamp under inclined installation or bumpy road conditions.
[0008] 3. The drainage channel design, combined with the water-guiding assembly on the back of the lamp body, further optimizes the drainage path of accumulated water. The protrusions in the water-guiding assembly are arranged in parallel, forming a water-guiding channel between adjacent protrusions. Openings are provided on both sides of the water-guiding channel to ensure that accumulated water can be quickly dispersed and discharged outside the lamp body. Simultaneously, the outlet of the drainage channel faces the opening of the water-guiding channel. This structural design allows accumulated water to smoothly flow from the drainage channel into the water-guiding channel and ultimately be discharged, reducing the time that water remains inside the lamp body. This reduces the risk of damage to electrical components and extends the service life of the driving light. Attached Figure Description

[0012] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0013] This application discloses a driving light, referring to... Figure 1 and Figure 2 It includes a lamp body 1, a lighting component 2 for illumination, and a mounting base 3. The mounting base 3 can be fixed to the roof of the vehicle. The mounting base 3 and the lamp body 1 are rotatably connected by a rotating structure so that the lamp body 1 is tilted on the roof of the vehicle. The lamp body 1 is provided with a receiving cavity 4, and the lighting component 2 is disposed in the receiving cavity 4 to emit a light beam.
[0014] Specifically, the mounting base 3 includes a fixing part 31 and a rotating part 32. The fixing part 31 is a circular plate structure for mounting the roof, and the rotating part 32 is a semi-circular structure. The outer surface of the rotating part 32 is provided with an adjustment part 33 to facilitate manual adjustment of the tilt angle of the lamp body 1 and the light assembly 2. The fixing part 31 and the rotating part 32 are connected by a bearing to ensure flexible rotation. The fixing part 31 of the mounting base 3 is provided with multiple threaded holes for fixed connection with the roof.
[0015] Specifically, the lighting assembly 2 includes a circular light plate 21 for protection and a light element 22 for emitting light. The light element 22 is installed in the receiving cavity 4. The light plate 21 is installed on the front surface of the lamp body 1 to protect the light element 22 within the receiving cavity 4. In this embodiment, the front surface of the lamp body 1 is provided with an annular glue groove 11 corresponding to the light plate 21. Four anti-overflow protrusions 12 are embedded in the glue groove, and the four anti-overflow protrusions 12 are evenly distributed within the annular glue groove 11. The height of the anti-overflow protrusions 12 is less than or equal to the height of the glue groove. When the circular light plate 21 is installed on the front surface of the lamp body 1, the inner surface of the light plate 21 contacts the anti-overflow protrusions 12. Then, glue is injected into the glue groove, and the light plate 21 is pressed down. The anti-overflow protrusions 12 abut against the light plate 21, blocking the tendency of the light plate 21 to continue pressing down, thereby effectively preventing the glue in the glue groove from overflowing. The glue groove is made of high-temperature resistant elastic rubber, which can maintain a sealing effect under extreme temperatures.
[0016] Specifically, the back of the lamp body 1 is provided with a protective partition 13, a vent 14, and a water guiding component 17, all of which protrude from the back surface of the lamp body 1. In this embodiment, there are two vent 14s, which are used for ventilation and drainage. The protective partition 13 forms an isolation cavity 15, which isolates the vent 14s within the isolation cavity 15, thus preventing water from flowing back into the lamp body 1. Furthermore, the protective partition 13 has a drain outlet below the vent 14 and a drainage channel 16. The drain outlet is connected to the isolation cavity 15 and the drainage channel 16. The drainage channel 16 extends downward along the opening of the protective partition 13. The drainage channel 16 has a rectangular structure, which allows the water accumulated in the isolation cavity 15 to flow away quickly along the drainage channel 16. No matter what tilt state the lamp component 2 is in or the vehicle is bumpy, the precise protection and isolation combined with the effective drainage function ultimately achieves a significant improvement in waterproof performance. The drainage channel 16 has a width ranging from 0.5cm to 2cm, providing sufficient space for water flow. The outlet of the drainage channel 16 faces the opening of the water guide assembly 17 to prevent water from flowing back into the lamp body 1. The drainage channel 16 is made of corrosion-resistant stainless steel, ensuring long-term use without damage.
[0017] Furthermore, the bottom of the lamp body 1 is provided with eight sets of trapezoidal water guiding components 17 for guiding water flow. Each set of water guiding components 17 includes several evenly spaced and parallel protrusions 171, forming a water guiding channel 172 between the protrusions 171. Openings are provided on both sides of the water guiding channel 172. The openings of the water guiding channels 172 of two adjacent sets of water guiding components 17 correspond one-to-one. The length of the water guiding channel 172 gradually shortens from the edge of the lamp body 1 to the middle of the lamp body 1, and the outlet direction of the drainage channel 16 faces the opening of the water guiding channel 172, allowing the water accumulated in the isolation chamber 15 to flow from the drainage channel 16 to the opening of the water guiding channel 172, and then flow out from the other opening of the water guiding channel 172 to the corresponding water guiding channel 172 of the adjacent water guiding component 17. The implementation principle of this embodiment is as follows: The driving lamp of this embodiment consists of a lamp body 1, a light component 2, and a mounting base 3. During installation, the lamp body 1 is first installed on the roof of the vehicle through the mounting base 3. The installation process of the lighting component 2 is as follows: the lighting component 22 is installed into the receiving cavity 4 of the lamp body 1. An annular groove 11 with four evenly distributed anti-overflow protrusions 12 with a height less than or equal to the height of the groove is pre-set on the front surface of the lamp body 1. The circular lamp plate 21 is installed on the front surface of the lamp body 1, so that the inner surface of the lamp plate 21 contacts the anti-overflow protrusions 12. Then, glue is injected into the groove and the lamp plate 21 is pressed. The anti-overflow protrusions 12 press against the lamp plate 21 to prevent the glue from overflowing. The groove is made of high-temperature resistant elastic rubber material to ensure the sealing effect under extreme temperatures. Two vent holes 14, a protective partition 13, and a water-guiding component 17 are protruding from the back surface of the lamp body 1. The protective partition 13 forms an isolation cavity 15 that isolates the vent holes 14. A drain outlet is opened below the vent holes 14 and connects to a drain channel 16. The drain channel 16 is made of corrosion-resistant stainless steel and has a width between 0.5cm and 2cm. The outlet faces the water-guiding component 17 for easy drainage. Eight sets of trapezoidal water-guiding components 17 are set at the bottom of the lamp body 1. Each set consists of several evenly spaced and parallel protrusions 171 forming a water-guiding channel 172. The openings of adjacent sets of water-guiding channels 172 correspond one-to-one. The length of the water-guiding channel 172 gradually shortens from the edge to the middle of the lamp body 1, and the outlet of the drain channel 16 faces the water-guiding channel 172. In this way, when the vehicle is in motion, no matter what tilt state the lamp component 2 is in or whether the vehicle is bumpy, the protective partition 13, together with the drain channel 16 and the water-guiding component 17, can accurately protect against water flow and quickly drain water, significantly improving waterproof performance.
[0018] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
