Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically a bus headlight module with a split heat dissipation frame. Background Technology

[0002] In modern bus manufacturing and operation, headlight modules, as key components for ensuring driving safety, face numerous challenges in terms of performance and reliability. However, existing bus headlight modules have some significant problems during use.

[0003] In terms of frame structure, traditional integrated designs have many drawbacks. Because the entire frame is an indivisible whole, if any small part is damaged, deformed, or worn, the entire headlight module frame must be replaced. This often requires specialized technicians and complex tools, increasing the difficulty and complexity of repairs. Furthermore, different parts of the bus headlight module face different working conditions and performance requirements in actual use. The inability to specifically optimize for these different needs means that the headlight module's performance in certain aspects cannot reach its optimal state, affecting the overall usability and lifespan.

[0004] For example, an automotive front-end module frame, as disclosed in announcement number CN202011430U, is characterized in that: the automotive front-end module frame is an integral part injection-molded, comprising a main frame for mounting automotive front-end components, a left-side frame for mounting the left headlight on the left side of the main frame, and a right-side frame for mounting the right headlight on the right side of the main frame. This module frame is an all-plastic frame, replacing the traditional specially welded frame, and also provides mounting points for components such as headlights, radiators, and hood locks. This reduces the number of production processes and space required by the OEM, reduces the number of vehicle parts, reduces mold investment, and lowers costs. When the aforementioned automotive front-end module frame is damaged or malfunctions, it often requires replacing the entire headlight module frame. It's not possible to replace only the damaged, deformed, or worn areas. However, other issues exist, such as insufficient heat dissipation technology in existing headlight modules. When headlights are on for extended periods, they generate significant heat. If this heat cannot be dissipated effectively, it will severely damage various headlight components. High temperatures accelerate the sublimation and melting of the bulb filament, greatly shortening its lifespan. Excessive heat can also cause thermal stress on internal electronic components, leading to performance degradation, malfunctions, or even damage, affecting light reflection and projection, and consequently reducing brightness and uniformity of illumination. Utility Model Content

[0005] The purpose of this utility model is to provide a bus headlight module with a split heat dissipation frame, in order to solve the problem mentioned in the background art that when a certain part is damaged or malfunctions, it is often necessary to replace the entire headlight module frame, which cannot replace the damaged, deformed or worn parts and cannot dissipate heat in a timely and effective manner, which will cause serious damage to various components of the headlight.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bus headlight module with a split heat dissipation frame, comprising a main frame and a sub-frame disposed on the left end of the main frame; a headlight module body is disposed between the main frame and the sub-frame; a fixed outer shell is fixedly installed inside the upper end of the main frame, and two fixed outer shells are evenly distributed around the main frame as the center of symmetry, and a guide groove is provided on the left side inside the fixed outer shell; a movable locking block is disposed inside the fixed outer shell, and guide blocks are disposed on both sides of the movable locking block; the guide groove on the fixed outer shell and the guide blocks on the movable locking block cooperate with each other; the main frame is provided with a press-type connecting mechanism, and a rotating locking block is rotatably installed on the left end of the movable locking block, and two rotating locking blocks are evenly distributed around the fixed outer shell as the center of symmetry; placement holes are provided on the outer sides of the main frame and the sub-frame, and the placement holes on the main frame and the sub-frame correspond to the headlight module body; a radiator is installed in the placement holes on the main frame and the sub-frame; a heat dissipation mechanism is provided on the headlight module body, and a cooling pipe is installed in the placement holes on the main frame and the sub-frame, and the cooling pipe is installed on the right end of the radiator.

[0007] Furthermore, the press-type connecting mechanism includes a spring installed at the right end inside the fixed housing, and the left end of the spring is installed at the right end of the movable block, and a card plate is rotatably installed at the upper end of the movable block.

[0008] Furthermore, a locking post is provided at the right end of the card plate, and a fixing block is fixedly installed inside the upper part of the fixed outer shell, and the fixing block cooperates with the locking post on the card plate.

[0009] Furthermore, a buckle is fixedly installed on the upper end of the sub-frame, and two buckles are evenly distributed with the sub-frame as the center of symmetry, and the buckles cooperate with the movable block.

[0010] Furthermore, the heat dissipation mechanism includes a heat dissipation water tank fixedly installed at the lower end of the main frame, and the heat dissipation water tank is filled with heat dissipation liquid and a cooler is installed inside the heat dissipation water tank.

[0011] Furthermore, a heat dissipation pipe is provided on the outer side of the headlight module body, and the rear end of the heat dissipation pipe is installed through the upper end of the heat dissipation tank.

[0012] Furthermore, the front end of the heat dissipation pipe is installed through the front end of the heat dissipation tank, and a circulation pump is installed at the front end of the heat dissipation pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the bus headlight module with a split heat dissipation frame;

[0014] 1. First, place the headlight module body on the main frame. Use the buckle on the sub-frame to push the moving block. Because the guide block of the moving block cooperates with the guide groove of the fixed shell, the moving block moves into the fixed shell and squeezes the spring. The card plate at the top of the moving block cooperates with the fixed block. The card plate locks the moving block. During the movement of the moving block into the fixed shell, its rotating block rotates inward and locks the buckle, making the maintenance work extremely simple and efficient.

[0015] Furthermore, when a component of the headlight module malfunctions or is damaged, maintenance personnel can quickly and accurately locate the problem and repair or replace only the affected part of the frame. This not only significantly shortens maintenance time and reduces the time buses are out of service due to headlight maintenance, thus improving vehicle operating efficiency, but also significantly reduces maintenance costs, saving a large amount of material and labor expenses. Different components can be manufactured using the most suitable materials according to their specific functions and usage environments.

[0016] Furthermore, it can quickly and accurately pinpoint the problem area and perform efficient repairs or replacements only on that part of the frame, greatly reducing the time required for repairs and significantly decreasing the downtime of buses due to headlight repairs. This significantly improves the operational efficiency of the vehicles and also significantly reduces maintenance costs. It eliminates the need to replace the entire frame, only requiring the treatment of the affected parts, which saves a lot of money on materials and labor, and improves production efficiency and the precision of quality control.

[0017] 2. When the headlight module body inside the main frame and sub-frame generates heat, the circulation pump delivers the heat dissipation liquid inside the radiator to the heat dissipation pipe. After the heat dissipation liquid in the heat dissipation pipe absorbs the heat generated by the headlight module body, it flows back to the radiator from the other end. The cooler inside the radiator dissipates the heat, which can quickly and evenly remove the large amount of heat generated when the headlight is working. This effectively reduces the working temperature of the internal components of the headlight.

[0018] Furthermore, it significantly extends the service life of key components such as bulb filaments, electronic components, lamp covers, and reflectors. The stable low-temperature working environment ensures that the bulb's luminous efficiency remains at a high level, the color temperature remains stable, and the brightness and color accuracy of the illumination are maintained for a long time, providing drivers with clear, stable, and reliable lighting light and greatly improving driving safety.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figures 1-7This utility model provides the following technical solution: a bus headlight module with a split heat dissipation frame, including a main frame 1 and a sub-frame 2 disposed on the left end of the main frame 1; a headlight module body 3 is disposed between the main frame 1 and the sub-frame 2; a fixed housing 4 is fixedly installed inside the upper end of the main frame 1, and two fixed housings 4 are evenly distributed around the main frame 1 as the center of symmetry; a guide groove is provided on the left side inside the fixed housing 4; a movable block 5 is disposed inside the fixed housing 4, and guide blocks are disposed on both sides of the movable block 5; and the guide groove on the fixed housing 4 and the guide block on the movable block 5 are connected. The main frame 1 is equipped with a press-type connecting mechanism, and a rotating block 6 is rotatably installed on the left end of the movable block 5. Two rotating blocks 6 are evenly distributed around the fixed housing 4 as the center of symmetry. Placement holes are opened on the outer sides of the main frame 1 and the sub-frame 2, and these placement holes correspond to the headlight module body 3. Heat sinks 7 are installed in the placement holes on the main frame 1 and the sub-frame 2. A heat dissipation mechanism is provided on the headlight module body 3, and a cooling pipe 8 is installed in the placement holes on the main frame 1 and the sub-frame 2. The cooling pipe 8 is installed on the right end of the heat sink 7. The press-type connecting mechanism includes a spring 9 installed on the right end inside the fixed housing 4, with the left end of the spring 9 installed on the right end of the movable block 5. A locking plate 10 is rotatably installed on the upper end of the movable block 5. A locking post is provided on the right end of the locking plate 10, and a fixing block 11 is fixedly installed on the upper end inside the fixed housing 4. The fixing block 11 and the locking post on the locking plate 10 cooperate with each other. A buckle 12 is fixedly installed on the upper end of the sub-frame 2, and two buckles 12 are evenly distributed with the sub-frame 2 as the center of symmetry, and the buckles 12 cooperate with the movable block 5.

[0029] When installing the headlight module body 3, first place the headlight module body 3 on the main frame 1. Then, use the buckle 12 on the sub-frame 2 to push the moving block 5. Because the guide block of the moving block 5 cooperates with the guide groove of the fixed housing 4, the moving block 5 moves into the fixed housing 4 and squeezes the spring 9. At this time, the locking plate 10 at the upper end of the moving block 5 cooperates with the fixed block 11, and the locking plate 10 locks the moving block 5. At the same time, during the process of the moving block 5 moving into the fixed housing 4, its rotating block 6 rotates inward and locks the buckle 12. When disassembling the headlight module body 3, press the sub-frame 2. The buckle 12 on the sub-frame 2 squeezes the moving block 5. The moving block 5 squeezes the spring 9, causing the locking plate 10 to release the fixed block 11. Then, the spring 9 pushes the moving block 5, causing the rotating block 6 to release the buckle 12.

[0030] The heat dissipation mechanism includes a heat dissipation tank 13 fixedly installed at the lower end of the main frame 1, with heat dissipation liquid inside the heat dissipation tank 13 and a cooler 14 inside the heat dissipation tank 13. A heat dissipation pipe 15 is provided on the outside of the headlight module body 3, and the rear end of the heat dissipation pipe 15 is installed through and installed at the upper end of the heat dissipation tank 13. The front end of the heat dissipation pipe 15 is installed through and installed at the front end of the heat dissipation tank 13, and a circulation pump 16 is installed at the front end of the heat dissipation pipe 15.

[0031] When the headlight module body 3 inside the main frame 1 and the sub-frame 2 generates heat, the radiators 7 on both sides of the main frame 1 and the sub-frame 2 are activated. The radiators 7 blow air inward and blow the cold air on the cooling pipe 8 into the interior. At the same time, the circulation pump 16 delivers the heat dissipation liquid inside the heat dissipation tank 13 to the heat dissipation pipe 15. After absorbing the heat generated by the headlight module body 3, the heat dissipation liquid in the heat dissipation pipe 15 flows back to the heat dissipation tank 13 from the other end, where the cooler 14 inside the heat dissipation tank 13 performs heat dissipation.
