Description
Technical Field
[0001] This utility model relates to the field of electric vehicle headlight technology, specifically a waterproof and dustproof electric vehicle headlight cover. Background Technology
[0002] When electric vehicles are driven at night, the headlights are one of the core components to ensure driving safety. The clarity and stability of the headlights are directly related to the rider's judgment of road conditions and the efficiency of obstacle avoidance, and are a key factor in reducing the risk of nighttime traffic accidents. However, most conventional electric vehicle headlight covers on the market currently suffer from insufficient protective performance, making them unsuitable for complex daily use scenarios. This has become a significant weakness restricting the reliable operation of the headlights. Ordinary headlight covers often use simple clip-on or adhesive sealing structures with low sealing redundancy. In urban commuting scenarios, road water and rainwater can easily seep into the headlight cover through gaps, causing short circuits in the headlight circuit and corrosion of the light source. Urban dust and mud splashes on suburban roads can easily cause dust and particles to accumulate on the inner wall of the headlight cover or the surface of the light source, resulting in light scattering, reduced illumination brightness, and significantly reduced nighttime visibility. At the same time, some headlight covers, due to structural design defects, are prone to loosening and sealing failure when the vehicle is bumpy. This not only exacerbates the decline in waterproof and dustproof capabilities but may also cause secondary safety risks due to the headlight cover falling off. For riders, frequent headlight cover replacements and headlight repairs not only increase operating costs but also put them in dangerous situations while riding at night due to temporary lighting failures.
[0003] However, the above technical solutions still have the following shortcomings in actual application: (1) The existing technology relies only on a single sealing ring or adhesive sealing, without multiple protection redundancy, and rainwater can easily seep in from the gap between the lampshade and the housing; and the sealing structure is not adapted to bumpy road conditions, and long-term use can easily lead to waterproof failure due to loosening of the fit, which poses a risk of short circuit; (2) The dustproof components of the existing structure are fixed integrated, which cannot be disassembled for cleaning or replacement. After dust accumulates, it is easy to adhere to the surface of the light source and block the ventilation channel, resulting in a decrease in lighting brightness, and there is no targeted dustproof design to adapt to complex dusty environments; (3) The existing structure lampshade is fixed without a stable limiting structure, and it is easy to reset and shift after angle adjustment; there is no status feedback between the outer lampshade and the housing, and the user cannot judge whether it is completely fixed. It may cause lighting abnormalities due to loosening of the fixation, and disassembly and assembly require special tools, which makes maintenance inconvenient. Utility Model Content
[0004] In view of the above technical problems, this utility model provides a waterproof and dustproof headlight cover for electric vehicles that is precise in positioning, double-sealed, and easy to disassemble.
[0005] This utility model provides a waterproof and dustproof headlight cover for electric vehicles, characterized in that it includes an outer housing, an outer lamp cover, a dustproof net, an inner cover unit, an adjustment unit, and a headlight. The outer lamp cover is detachably connected to the outer housing, and the dustproof net is detachably connected to the side wall of the outer housing. The adjustment unit is fixedly connected inside the outer housing, and the inner cover unit is detachably connected to the outside of the adjustment unit. The headlight is located at the center of the adjustment unit. The dustproof net is detachably connected to the side wall of the outer housing. The mesh structure of the dustproof net can effectively intercept dust, sand, and other impurities in the air, preventing impurities from adhering to the surface of the headlight or entering the adjustment unit and affecting the operation of moving parts. When the dustproof net has too much dust on its surface, it can be directly disassembled for cleaning or replacement.
[0006] The rear wall of the outer casing is fixedly connected to a terminal block, which is connected to the vehicle light via wires. Fixing plates are welded to both sides of the outer casing and secured to the electric vehicle body with bolts, ensuring the stability of the entire device under bumpy road conditions and preventing component loosening due to vibration. A raised ridge is provided at the top of the front wall of the outer casing, and a front cover is hinged to the ridge. A buckle is connected to the front cover. Two raised blocks are welded to the bottom of the front wall of the outer casing, each with a slot for the outer cover. The size of the outer cover slot corresponds to the outer light cover, allowing for direct and reliable fixing of the outer light cover through size adaptation, ensuring the stability of the outer light cover as the main light-emitting window. The front cover is fastened to the bottom structure of the outer casing via buckles, pressing the edge of the outer light cover to eliminate assembly gaps and engaging with the raised ridge of the outer casing. The tight fit of the eaves forms a second seal, achieving double sealing reinforcement. This not only prevents rainwater and dust from intruding through the gaps between the outer lamp cover and the outer cover groove, but also shields the edge area of the outer lamp cover, preventing damage to the edge of the outer lamp cover caused by flying stones or minor bumps during riding. Furthermore, the outer lamp cover can be easily removed without additional tools; simply press the buckle to unlock the front cover. After opening the front cover, the outer lamp cover remains stable due to its positioning in the outer cover groove and will not fall off. A gentle push on the edge of the outer lamp cover allows it to be removed from the outer cover groove without disassembling other components, meeting the need for easy disassembly and replacement. The terminal block is fixed to the rear side wall of the outer casing, establishing a stable electrical connection with the vehicle light via a wire to supply power to the light. The terminal block maintains a reasonable spatial distance from the vehicle light to avoid poor wiring contact caused by vibration, improving the reliability of the electrical system.
[0007] The inner cover unit includes an inner lampshade, a limiting ring, and a fixing hole. The limiting ring is fixedly connected to the upper part of the inner wall of the inner lampshade, and a fixing hole is opened at the bottom of the inner wall of the inner lampshade.
[0008] The adjustment unit includes a base, a movable ring, a limiting groove, a limiting post, a connecting rod, a fixed seat, a connecting rod, a movable plate, and a limiting buckle. The base is fixedly connected to the front side wall of the outer casing. A limiting post is fixedly connected to the base. A movable ring is provided on the base, and a limiting groove is formed on the movable ring. The limiting post is fixed to the base and passes through the limiting groove of the movable ring. A connecting rod is fixedly connected to the top of the movable ring. A fixed seat is fixedly connected to the inner side of the movable ring. A connecting rod is rotatably connected to the fixed seat. The other end of the connecting rod is rotatably connected to the movable plate. The other side of the movable plate is hinged to the base by bolts. A limiting buckle is fixedly connected to the movable plate.
[0009] The headlight is fixedly connected to the center of the base, and the back of the headlight is electrically connected to the terminal block.
[0010] The fixing hole in the inner cover unit is detachably connected to the connecting rod in the adjustment unit for initial positioning. The limiting ring in the inner cover unit engages with the limiting buckle in the adjustment unit to fix the inner lamp cover. First, align the fixing hole in the inner cover unit with the connecting rod in the adjustment unit, then rotate the inner cover unit. The movable ring rotates under the action of the inner lamp cover and the connecting rod. The movable ring slides under the limiting action of the limiting post and the limiting groove, causing the fixing seat fixedly connected to the inner wall of the movable ring to move synchronously. The fixing seat drives the connecting rod to rotate, which in turn drives the movable plate to rotate around the bolt. At this time, the limiting buckle fixed on the top of the movable plate engages with the limiting ring of the inner cover unit to fix the inner cover unit. If the inner cover unit is not completely fixed, that is, the limiting buckle is not engaged with the limiting ring, the edge of the movable plate will block part of the light from the vehicle headlight. The rider can judge whether it is completely fixed by the lighting effect. When the limiting buckle is fully engaged with the limiting ring, the movable plate no longer blocks the light from the vehicle headlight.
[0011] The beneficial effects of this utility model are as follows: This utility model provides a waterproof and dustproof electric vehicle headlight cover. By setting three sealing structures, namely, outer cover groove positioning, front cover buckle pressing and raised eaves cooperation, the problem of leakage of single seal is solved. At the same time, the components are closely matched, which is suitable for bumpy road conditions. It can maintain a stable waterproof effect even after long-term use and avoid the risk of short circuit. By using a detachable dustproof screen, dust can be cleaned or replaced directly after accumulation, avoiding the drawback of fixed dustproof structures that can only be used once; at the same time, it does not affect internal ventilation and heat dissipation, achieving a balance between dust prevention and function, and extending the service life of the device. By setting up an inner cover unit and an adjustment unit, and using the design of initial positioning with connecting columns and limiting holes, and complete fixation with limiting buckles and limiting rings, not only are the problems of adjustment jamming and easy reset solved, but it also has a fixed status reminder function. When not fully fixed, the movable plate will block the light, intuitively prompting the user to adjust. After being fully fixed, the movable plate will automatically move aside to ensure unobstructed lighting. This avoids the safety hazards caused by loosening and eliminates the need for additional inspection steps, making it more worry-free to use. At the same time, the outer lamp cover is doubly fixed by positioning with the outer cover groove and locking with buckles. No special tools are required for disassembly and assembly, improving maintenance efficiency. Attached Figure Description

Detailed Implementation Example 1
[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.
[0014] As shown in the figure, this utility model provides a waterproof and dustproof headlight cover for electric vehicles. It is characterized by comprising an outer housing 1, an outer lamp cover 2, a dustproof net 3, an inner cover unit 4, an adjustment unit 5, and a headlight 6. The outer lamp cover 2 is detachably connected to the outer housing 1, and the dustproof net 3 is detachably connected to the side wall of the outer housing 1. The adjustment unit 5 is fixedly connected inside the outer housing 1, and the inner cover unit 4 is detachably connected to the outside of the adjustment unit 5. The headlight 6 is located at the center of the adjustment unit 5. The dustproof net 3 is detachably connected to the side wall of the outer housing 1. The mesh structure of the dustproof net 3 can effectively intercept dust, sand, and other impurities in the air, preventing impurities from adhering to the surface of the headlight 6 or entering the adjustment unit 5 and affecting the operation of moving parts. When the surface of the dustproof net 3 accumulates too much dust, it can be directly disassembled for cleaning or replacement.
[0015] The rear wall of the outer casing 1 is fixedly connected to a terminal block 11, which is connected to the vehicle lamp 6 via a wire. Fixing plates 12 are welded to both sides of the outer casing 1 and secured to the electric vehicle body with bolts, ensuring the stability of the entire device under bumpy road conditions and preventing component loosening due to vibration. A raised ridge is provided at the top of the front wall of the outer casing 1, and a front cover 13 is hinged to the ridge. A buckle 14 is connected to the front cover 13. Two raised blocks are welded to the bottom of the front wall of the outer casing 1, each with an outer cover groove 15. The size of the outer cover groove 15 corresponds to the outer lamp cover 2. The outer cover groove 15 achieves direct and reliable fixing of the outer lamp cover 2 through size adaptation, ensuring the stability of the outer lamp cover 2 as the main light-emitting window. The front cover 13 is fastened to the bottom structure of the outer casing 1 via the buckle 14, pressing the edge of the outer lamp cover 2 to eliminate assembly gaps. The outer casing 1's raised eaves form a second seal, achieving double sealing reinforcement. This not only prevents rainwater and dust from entering through the gap between the outer lamp cover 2 and the outer cover groove 15, but also shields the edge area of the outer lamp cover 2, preventing damage to the edge of the outer lamp cover 2 caused by flying stones or minor bumps during riding. At the same time, the outer lamp cover 2 can be removed without additional tools and is easy to operate. Simply press the buckle 14 to unlock the front cover 13 without tools. After opening the front cover 13, the outer lamp cover 2 remains stable due to the positioning of the outer cover groove 15 and will not fall off. The edge of the outer lamp cover 2 can be gently pushed out of the outer cover groove 15 without disassembling other parts, meeting the need for easy disassembly and replacement. Meanwhile, the terminal 11 is fixed to the rear side wall of the outer casing 1, establishing a stable electrical connection with the vehicle light 6 through the wire, supplying power to the vehicle light 6. The terminal 11 and the vehicle light 6 maintain a reasonable spatial distance to avoid poor wiring contact caused by vibration, improving the reliability of the electrical system.
[0016] The inner cover unit 4 includes an inner lamp cover 41, a limiting ring 42, and a fixing hole 43. The limiting ring 42 is fixedly connected to the upper part of the inner wall of the inner lamp cover 41, and the fixing hole 43 is opened at the bottom of the inner wall of the inner lamp cover 41.
[0017] The adjustment unit 5 includes a base 51, a movable ring 52, a limiting groove 53, a limiting post 54, a connecting rod 55, a fixed seat 56, a connecting rod 57, a movable plate 58, and a limiting buckle 59. The base 51 is fixedly connected to the front side wall of the outer casing 1. The limiting post 54 is fixedly connected to the base 51. The movable ring 52 is provided on the base 51. The limiting groove 53 is opened on the movable ring 52. The limiting post 54 is fixed to the base 51 and passes through the limiting groove 53 of the movable ring 52. The connecting rod 55 is fixedly connected to the top of the movable ring 52. The fixed seat 56 is fixedly connected to the inner side of the movable ring 52. The connecting rod 57 is rotatably connected to the fixed seat 56. The other end of the connecting rod 57 is rotatably connected to the movable plate 58. The other side of the movable plate 58 is hinged to the base 51 by bolts. The limiting buckle 59 is fixedly connected to the movable plate 58.
[0018] The vehicle light 6 is fixedly connected to the center of the base 51, and the back side of the vehicle light 6 is electrically connected to the terminal block 11.
[0019] The fixing hole 43 in the inner cover unit 4 is detachably connected to the connecting rod 55 in the adjustment unit 5 for initial positioning. The limiting ring 42 in the inner cover unit 4 engages with the limiting buckle 59 in the adjustment unit 5 to fix the inner lampshade 41. First, align the fixing hole 43 in the inner cover unit 4 with the connecting rod 55 in the adjustment unit 5. Then, rotate the inner cover unit 4. The movable ring 52 rotates under the action of the inner lampshade 41 and the connecting rod 55. The movable ring 52 slides under the limiting action of the limiting post 54 and the limiting groove 53, driving the fixed connection of the inner wall of the movable ring 52. The fixed seat 56 moves synchronously, driving the connecting rod 57 to rotate, which in turn drives the movable plate 58 to rotate around the bolt. At this time, the limiting buckle 59 fixed on the top of the movable plate 58 engages with the limiting ring 42 of the inner cover unit 4, thus fixing the inner cover unit 4. If the inner cover unit 4 is not completely fixed, that is, if the limiting buckle 59 is not engaged with the limiting ring 42, the edge of the movable plate 58 will block part of the light from the headlight 6. The rider can judge whether it is completely fixed by the lighting effect. When the limiting buckle 59 is fully engaged with the limiting ring 42, the movable plate 58 no longer blocks the light from the headlight 6. Example 2
[0020] When using this utility model: first, align the fixing plates 12 on both sides of the outer box 1 with the preset installation positions of the electric vehicle body, and then tighten them by bolting through the fixing plates 12 and the mounting holes of the vehicle body to ensure that the outer box 1 is firmly connected to the vehicle body, avoid loosening or displacement under bumpy road conditions, and provide stable support for all subsequent components.
[0021] Holding the inner cover unit 4, align the fixing hole 43 at the bottom of the inner lamp cover 41 with the connecting rod 55 on the base 51 in the adjustment unit 5, and insert it along the axial direction of the connecting rod 55 to achieve initial positioning; then rotate the inner cover unit 4 clockwise, causing the movable ring 52 to rotate synchronously. The movable ring 52 slides along the limiting post 54 through the limiting groove 53, and the fixing seat 56 on its inner side moves with the movable ring 52, thereby pulling the connecting rod 57 to rotate. The connecting rod 57 drives the movable plate 58 to rotate around the bolt connected to the base 51. Continue to rotate the inner cover unit 4 and observe whether the limiting buckle 59 and the limiting ring 42 on the inner wall of the inner lamp cover 41 are fully engaged. When the movable plate 58 rotates to a position parallel to the lighting direction of the headlight 6 and no longer blocks the light, it indicates that the inner cover unit 4 has been fixed in place; if the headlight 6 is still blocked after rotation, it means that the engagement is not in place, and the rotation angle of the inner cover unit 4 needs to be finely adjusted until the lighting is unobstructed.
[0022] First, install the dustproof net 3 on the side wall of the outer casing 1. The mesh structure of the dustproof net 3 can intercept dust, sand and other impurities in the air in real time, forming a dustproof barrier inside the outer casing 1 in advance. Then, align the outer lamp cover 2 with the outer cover groove 15 of the protrusion at the bottom of the front side wall of the outer casing 1 and insert it along the groove. The outer cover groove 15, through precise size matching, forms a direct and reliable circumferential fixation for the outer lamp cover 2, and at the same time achieves the first seal. Then, flip the front cover 13 around the hinge so that the front cover 13 fits against the protruding eaves on the top of the outer casing 1, and press the buckle 14 on the front cover 13 to make it engage with the protrusion. Fastening and locking: The front cover 13 is then pressed against the edge of the outer lamp cover with only slight pressure. This strengthens the sealing effect, forming a second barrier, and prevents the outer lamp cover 2 from shifting slightly due to bumps. It also protects the edge of the outer lamp cover from impact damage. Then, the electric vehicle power supply line is connected and fixed to the terminal 11 on the rear side wall of the outer box 1. The power supply path is made through the pre-set wire between the terminal 11 and the headlight 6. The terminal 11 and the headlight 6 are kept at a reasonable distance to avoid the wires being pulled or making poor contact due to vehicle vibration, and to ensure a stable power supply to the headlight 6.
[0023] If the inner cover unit 4 becomes slightly loose due to severe bumps during riding, and the limiting buckle 59 and the limiting ring 42 partially disengage, the movable plate 58 will rotate accordingly, blocking part of the light from the headlight 6. The rider can visually detect the abnormality through the nighttime lighting effect. After stopping, simply rotate the inner cover unit 4 again to fully engage the limiting buckle 59 and the limiting ring 42 to restore normal lighting. No additional tools are required for inspection or repair.
[0024] When excessive dust accumulation on the surface of the dustproof net 3 is observed, affecting ventilation or appearance, the front cover 13 can be unlocked first, the outer lamp cover 2 removed, and then the dustproof net 3 pulled outward along the mounting groove on the side wall of the outer casing 1. The net can be rinsed with clean water or cleaned with a brush to remove impurities from the mesh. After drying, it can be re-inserted into the mounting groove. If the dustproof net 3 is damaged, it can be directly replaced with a new dustproof net 3. Then, the outer lamp cover 2 can be reinstalled and the front cover 13 can be closed. The whole process does not require disassembling other core components and is simple to operate.
