Description

Technical Field

[0001] This utility model relates to the field of emergency construction lighting technology, specifically to a dimmable and color-adjustable engineering vehicle light. Background Technology

[0002] As modern engineering operations become increasingly complex (such as nighttime construction, tunnel lighting, and field repairs), traditional engineering vehicle lights, due to their limited functionality and poor adaptability, can no longer meet the demands. Dimmable and color-adjustable engineering vehicle lights, by integrating multi-channel LED drivers, color temperature mixing algorithms, and intelligent control technology, achieve dynamic adjustment of brightness and color temperature, significantly improving work efficiency and safety. For example, in foggy environments, the color temperature can be lowered to enhance penetration, while in tunnels, it can switch to cool white light to improve long-distance visibility.

[0003] In the existing technology, there is a lack of quick connection mechanism between the engineering vehicle lights and the mounting components on the engineering vehicle. This makes the disassembly and assembly of engineering vehicle lights overly reliant on special tools, which further increases the maintenance difficulty of engineering vehicle lights. Therefore, we need to propose an adjustable dimming and color-adjustable engineering vehicle light. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A dimmable and color-adjustable engineering vehicle light includes a positioning base plate 1. The positioning base plate 1 is made of high-strength aluminum alloy and has an anodized surface, which provides lightweight and corrosion resistance. The positioning base plate 1 is laser-cut with positioning holes to ensure compatibility with the mounting surface of the engineering vehicle. The positioning base plate 1 is fixedly connected to the engineering vehicle (not shown in the figure). A mounting seat 2 is fixedly installed on the top of the positioning base plate 1. A bracket 3 is set on the top of the mounting seat 2. The vehicle light body 4 is fixedly installed on the inner wall of the bracket 3. The vehicle light body 4 is fixed in the aluminum alloy U-shaped groove of the bracket 3 by fastening screws. The bracket 3 and the T-shaped block 5 are made of one piece using a casting process. The vehicle light body 4 is selected from the Philips Luxeon 30302D series. The vehicle light body 4 integrates a dual-color temperature LED light source module (such as 5000K cool white light and 3000K warm white light), supports stepless color temperature adjustment through light mixing technology, and has a built-in PWM dimming drive circuit, which can cover the brightness range of 10%-100%.

[0023] Two sets of T-blocks 5 are fixedly connected to the bottom of the bracket 3. Both sets of T-blocks 5 are inserted into the inside of the fixing seat 2. The fixing seat 2 has a clearance groove 6 inside. The fixing seat 2 is welded and fixed to the positioning base plate 1. The slot 10 and clearance groove 6 are milled inside. The width of the slot 10 matches the flange of the T-block 5. The clearance groove 6 is provided with a clamping component 7 for quick installation and removal of the T-block 5. The fixing seat 2 and the bracket 3 are initially positioned by inserting the T-block 5. The clamping component 7 completes the secondary locking, forming a double fixing structure to ensure that the headlight remains stable under severe vibration.

[0024] By fixing the positioning base plate 1 to the engineering vehicle, the positioning base plate 1 and the fixing seat 2 constitute the installation components on the engineering vehicle. By opening the clearance groove 6 inside the fixing seat 2 and coordinating the clamping component 7 with the T-block 5, the effect of quickly assembling and disassembling the headlight body 4 together with the bracket 3 is achieved, which significantly reduces the maintenance and replacement cost of the headlight body 4.

[0025] The clamping assembly 7 includes a positioning block 701, which is made of nylon and coated with a wear-resistant coating to reduce frictional wear with the T-block 5. The positioning block 701 is slidably inserted into the interior of the relief groove 6. One end of the positioning block 701 is inserted into the interior of the T-block 5, and a spring 702 is fixedly connected to the side of the positioning block 701 away from the T-block 5. One end of the spring 702 is fixedly connected to the inner wall of one side of the relief groove 6. The spring 702 is a compression spring, and the preload force is experimentally optimized and set to 50N to ensure that the positioning block 701 can be stably clamped into the groove 9 of the T-block 5 without external force, while allowing the clamping state to be released by applying external force through the pull rod 703.

[0026] A wedge-shaped part 8 is provided on one side wall of the positioning block 701, and a slot 9 adapted to the wedge-shaped part 8 is provided on one side wall of the T-shaped block 5. The wedge-shaped part 8 is inserted into the slot 9. The bevel angle of the wedge-shaped part 8 is designed to be 15°, which matches the inlet chamfer of the slot 9, ensuring that the positioning block 701 can automatically slide into the slot 9 when the T-shaped block 5 is inserted.

[0027] It also includes a pull rod 703, which is slidably inserted into the interior of the fixed base 2. One end of the pull rod 703 passes through the fixed base 2 and is fixedly connected to one side of the positioning block 701. The spring 702 is movably sleeved on the outer wall of the pull rod 703. The pull rod 703 is made of stainless steel and has anti-slip texture on the exposed end. The exposed ends of two adjacent sets of pull rods 703 can be fixedly connected by a connecting rod. When the pull rod 703 is pulled, the positioning block 701 moves backward synchronously to compress the spring 702. The wedge-shaped part 8 disengages from the slot 9. At this time, the T-shaped block 5 can slide freely to realize the quick disassembly of the bracket 3. After the pull rod 703 is released, the spring 702 pushes the positioning block 701 to reset and completes the self-locking.

[0028] The fixed base 2 has a slot 10 inside that is adapted to the T-block 5. The T-block 5 is slidably inserted into the slot 10. The inner wall of the slot 10 is coated with polytetrafluoroethylene to reduce the coefficient of friction when the T-block 5 slides. The lateral width of the T-block 5 is 0.5mm smaller than that of the slot 10 to ensure smooth insertion and avoid lateral wobbling, thereby improving structural stability.

[0029] A plug 11 is fixedly connected to one side wall of each of the two sets of T-blocks 5. A socket 12 is fixedly connected to the top of the positioning base plate 1. The plug 11 passes through the fixing seat 2 and is inserted into the inside of the socket 12. The plug 11 and the socket 12 are waterproof aviation plugs with IP67 protection rating. The internal contacts are gold-plated to reduce contact resistance and enable simultaneous disassembly and assembly of electrical and mechanical structures.

[0030] The positioning base plate 1 has several sets of positioning holes, and several sets of bolts 13 are respectively set inside the several sets of positioning holes. The positioning base plate 1 is bolted and fixed to the engineering vehicle by the several sets of bolts 13. The positioning holes adopt a waist-shaped hole design, which allows for ±5mm of installation position adjustment to adapt to the installation requirements of different vehicle models. The bolts 13 are M8 grade stainless steel bolts, which are used with anti-loosening nuts to ensure that they do not loosen for a long time under vibration environment.

[0031] Working principle: Installation process: Fix the positioning base plate 1 to the preset position of the engineering vehicle with bolts 13, align the T-shaped block 5 at the bottom of the bracket 3 with the slot 10 of the fixing seat 2 and insert it. The T-shaped block 5 pushes the positioning block 701 to compress the spring 702. The wedge-shaped part 8 slides over the chamfered entrance of the slot 9. When the T-shaped block 5 is fully inserted, the spring 702 returns to its original position and pushes the positioning block 701. The wedge-shaped part 8 is engaged in the slot 9 to achieve mechanical locking. At the same time, the plug 11 on the side wall of the T-shaped block 5 is automatically inserted into the socket 12 of the positioning base plate 1 to complete the electrical connection.

[0032] Disassembly process: Pull the lever 703, the positioning block 701 moves backward to disengage the wedge 8 from the slot 9, the T-shaped block 5 slides out of the slot 10, the plug 11 disengages from the socket 12 at the same time, release the lever 703, the spring 702 pushes the positioning block 701 to reset, and the disassembly is completed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
