Description

Technical Field

[0001] This utility model relates to the field of electric vehicle lights, and in particular to a sealed electric vehicle light structure with waterproof and dustproof functions. Background Technology

[0002] In the safe driving system of two-wheeled and three-wheeled electric vehicles, the headlights play a crucial role. They are not only the core device for nighttime illumination but also a key signal carrier for conveying driving intentions. With the widespread use of electric vehicles in urban short-distance commuting and rural transportation, their operating environments are becoming increasingly complex and diverse. They not only have to withstand the tests of natural environments such as sun, rain, and sandstorms but also experience continuous mechanical stress due to road bumps and vehicle vibrations. Therefore, the sealing performance of the headlights directly affects their service life and operational stability. If the seal fails, allowing moisture and dust to intrude, it can cause dim or flickering lights, or even short circuits and damage to the lights, posing a significant threat to riding safety.

[0003] Currently, most two-wheeled and three-wheeled electric vehicle lights on the market use a single threaded connection structure for sealing the lens cover and connecting shell. The technical principle is that the external thread on the edge of the lens cover meshes with the internal thread at the port of the connecting shell. During tightening, the friction between the threads ensures a tight seal. Simultaneously, a rubber sealing ring is placed on the contact surface. The axial pressure generated by the threaded connection compresses the sealing ring, causing it to elastically deform and fill any gaps, thus achieving a seal. Some products add nuts for reinforcement on top of the threaded connection, using the relative locking of two nuts to enhance the stability of the connection, but essentially it still relies on the locking force generated by the threaded engagement.

[0004] However, this sealing structure relying solely on threaded connections has significant drawbacks in long-term use. As electric vehicles inevitably vibrate during operation, and with the passage of time, the friction between the threads gradually weakens, easily leading to loosening of the threaded connection. Once the connection loosens, the originally tightly compressed sealing ring loses sufficient pressure and cannot effectively fill the gap between the lamp cover and the connecting shell, resulting in sealing failure. This allows moisture, dust, and other impurities to penetrate into the lamp, affecting the normal operation and lifespan of the lamp. Therefore, a sealed electric vehicle lamp structure with waterproof and dustproof functions is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a sealed electric vehicle lamp structure with waterproof and dustproof functions, aiming to improve the problem of loosening of threaded connections due to long-term use or vibration in the prior art, which leads to sealing failure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sealed electric vehicle lamp structure with waterproof and dustproof functions includes a connecting shell, a bulb is threadedly connected to one side of the connecting shell, a lamp cover is provided on one side of the connecting shell, a sealing component is provided between the lamp cover and the connecting shell, and an adjustment component is provided on the outer wall of the connecting shell.

[0008] The sealing assembly includes a sealing ring located between the lampshade and the connecting shell. A fixing ring is fixedly connected to one side of the connecting shell, and the sealing ring is in contact with one end of the fixing ring. A connecting cylinder is fixedly connected to one side of the lampshade, and a connecting ring is fixedly connected to one end of the connecting cylinder. The sealing ring is slidably connected to the inner wall of the connecting cylinder. The connecting ring is threadedly connected to the outer wall of the fixing ring. A protective sleeve is fixedly connected to the outer wall of the lampshade, and a fixing ring is fixedly connected to one end of the protective sleeve. A locking assembly is provided between the fixing ring and the connecting shell.

[0009] As a further description of the above technical solution:

[0010] The engaging assembly includes multiple locking pins and locking balls. The multiple locking pins and locking balls engage with the grooves on the outer side wall of the connecting shell. Multiple fixing shells are fixedly connected inside the fixing ring.

[0011] As a further description of the above technical solution:

[0012] Each of the fixed housings has a transmission rod slidably connected inside, one end of each transmission rod is fixedly connected to the outer wall of the locking post, and each locking post is slidably connected to the inner wall of the fixed housing.

[0013] As a further description of the above technical solution:

[0014] Each of the locking posts is provided with multiple springs, one end of each spring is fixedly connected to the outer wall of the locking ball, and the other end of each spring is fixedly connected to the inside of the locking post.

[0015] As a further description of the above technical solution:

[0016] Each of the transmission rods has a rotating bar running through it, and each rotating bar has a push block rotatably connected to its outer wall. Each push block is in contact with the fixed shell, and each rotating bar is located on one side of the center point of the push block.

[0017] As a further description of the above technical solution:

[0018] The adjustment assembly includes a rotating shaft located at the bottom of the connecting shell. A connecting block is fixedly connected to the bottom of the connecting shell, and the connecting block is rotatably connected to the outer wall of the rotating shaft.

[0019] As a further description of the above technical solution:

[0020] Both ends of the rotating shaft are fixedly connected to support blocks and connecting rings II. Each support block and connecting ring II are in contact with each other, and a connecting rod is fixedly connected between the support blocks on both sides.

The multiple retaining balls engage with the grooves on the outer wall of the rotating shaft.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the sealing ring is initially compressed by the threaded connection between the connecting ring and the fixing ring. Then, by rotating the pushing block, the eccentrically designed rotating bar drives the locking pin and the locking ball to engage with the groove on the surface of the connecting shell, forming a double-locking sealing structure. This solves the problem of loosening of the threaded connection due to long-term use or vibration in the prior art, which leads to sealing failure. The mechanical engagement provides a durable and reliable secondary locking force, thereby ensuring a long-term tight fit between the lampshade and the connecting shell and enhancing the overall waterproof and dustproof effect of the product.

[0025] 2. In this utility model, the connecting block rotates on the outer wall of the rotating shaft, and the elastic force of the second spring pushes the second locking ball to engage with the groove on the outer wall of the rotating shaft, thus realizing a convenient and reliable angle-division fixing function. When the lamp is rotated to the appropriate angle, the second locking ball can automatically fall into the groove to complete the locking. The operation is simple and intuitive, and the fixing is firm. No additional tools are needed. This not only improves the convenience of users when adjusting the angle of the lamp, but also ensures the stability after the angle is fixed, thereby achieving a good application effect and enabling the product to better adapt to diverse usage environments.

[0033] 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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of a sealed electric vehicle lamp structure with waterproof and dustproof functions, including a connecting shell 2. A bulb 3 is threadedly connected to one side of the connecting shell 2. The bulb 3 serves as the core light-emitting element of the device. The connecting shell 2 serves as the main frame of the device for installing and connecting various components. A lampshade 1 made of high light transmittance PMMA material is provided on one side of the connecting shell 2. The lampshade 1 is used to protect the bulb 3 and diffuse the light evenly. A sealing component is provided between the lampshade 1 and the connecting shell 2. The core function of the sealing component is to achieve a long-term tight fit between the lampshade 1 and the connecting shell 2 through a multi-locking structure, thereby achieving excellent waterproof and dustproof effects. An adjustment component is provided on the outer wall of the connecting shell 2. The adjustment component is used to conveniently adjust the illumination direction and angle of the lamp, enhancing the applicability of the lamp in different application scenarios.

[0035] The sealing assembly includes a sealing ring 7 made of weather-resistant silicone rubber. This sealing ring 7 fills the gap between the lampshade 1 and the connecting shell 2 to form a physical sealing layer. The sealing ring 7 is located between the lampshade 1 and the connecting shell 2. A retaining ring 8 made of 304 stainless steel is fixedly connected to one side of the connecting shell 2, and the sealing ring 7 fits against one end of the retaining ring 8. A connecting cylinder 5 is fixedly connected to one side of the lampshade 1, and a connecting ring 6 is fixedly connected to one end of the connecting cylinder 5. The sealing ring 7 is slidably connected to the inner wall of the connecting cylinder 5. The connecting ring 6 engages with the retaining ring 8 through a threaded connection, achieving a sealing ring compression effect through rotation. 7. This causes elastic deformation, thereby achieving a preliminary tight seal. A protective sleeve 4 is fixedly connected to the outer wall of the lampshade 1. A fixing ring 9 is fixedly connected to one end of the protective sleeve 4. A locking assembly is provided between the fixing ring 9 and the connecting shell 2. This locking assembly provides a strong secondary mechanical locking force to prevent the threaded connection between the connecting ring 6 and the fixing ring 8 from loosening due to vibration or long-term use, ensuring the durability of the seal. The locking assembly includes multiple locking posts 14 and locking balls 15. The multiple locking posts 14 and locking balls 15 engage with the groove on the outer wall of the connecting shell 2 to achieve a tight seal. The connecting shell 2 is physically limited. Multiple fixed shells 10 are fixedly connected inside the fixed ring 2 9. A transmission rod 13 is slidably connected inside each fixed shell 10. One end of each transmission rod 13 is fixedly connected to the outer wall of the locking post 14 to transmit the thrust generated by rotation to the locking post 14. Each locking post 14 is slidably connected to the inner wall of the fixed shell 10. Multiple highly elastic springs 16 are installed inside each locking post 14. One end of each spring 16 is fixedly connected to the outer wall of the locking ball 15, and the other end of each spring 16 is fixedly connected to the inside of the locking post 14 to utilize its storage... The stored elastic potential energy pushes the locking ball 15 to be stably locked into a specific groove, forming a stable auxiliary locking. Each transmission rod 13 has a rotating bar 12 connected through it. Each rotating bar 12 has a push block 11 rotatably connected to its outer wall. Each push block 11 is in contact with the fixed shell 10. Each push block 11 cooperates with the rotating bar 12 to perform eccentric rotational motion, which achieves the effect of efficiently converting the operator's rotational action into the linear motion of the transmission rod 13. Each rotating bar 12 is located on one side of the center point of the push block 11. This eccentric design is the core key structure for realizing the conversion of rotational torque into linear thrust.

[0036] Reference Figure 1 and Figure 5The adjustment assembly includes a rotating shaft 18 as the center of rotation. This assembly is used to achieve precise fixing and convenient adjustment of the illumination angle of the lamp, achieving good applicability. The rotating shaft 18 is located at the bottom of the connecting shell 2. A connecting block 17 is fixedly connected to the bottom of the connecting shell 2. The connecting block 17 is rotatably connected to the outer wall of the rotating shaft 18, used to support and drive the entire connecting shell 2 to deflect at an angle. Support blocks 21 and connecting rings 22 are fixedly connected to both ends of the rotating shaft 18, used to stably install the entire lamp in a predetermined position such as on the ceiling or wall. Each support block 21 fits against the connecting ring 22. A connecting rod 23 is fixedly connected between the components. This connecting rod 23 is used to enhance the structural strength and stability of the entire adjustment assembly and prevent deformation. Multiple springs 19 are provided inside the connecting block 17. One end of each spring 19 is fixedly connected to a retaining ball 20. The other ends of the multiple springs 19 are fixedly connected inside the connecting block 17. The multiple retaining balls 20 engage with multiple grooves on the outer wall of the rotating shaft 18. When the connecting shell 2 rotates to a suitable angle, the elastic restoring force of the springs 19 pushes the retaining balls 20 to automatically engage with the grooves, thereby achieving the effect of quickly locking and fixing the angle of the connecting shell 2.

[0037] Working principle: During the sealing process between the lampshade 1 and the connecting shell 2, the sealing ring 7 fixed inside the connecting cylinder 5 is moved to one side of the sealing ring 7 surface. Then, by rotating the connecting ring 6, the connecting ring 6 and the fixing ring 8 are threadedly connected and fixed. Next, the pushing block 11 is rotated. Since the rotating bar 12 is located on one side of the center point of the pushing block 11, it will drive the transmission rod 13 and the locking pin 14 to slide on the inner wall of the fixing shell 10 until they are engaged with the groove on the surface of the connecting shell 2. The elasticity of the spring 16 is used to engage the locking ball 15 on the specific groove surface, thereby ensuring that the sealing ring 7 is always fully in contact with one side of the fixing ring 8, achieving a sealing effect on the product surface, preventing water or dust from entering the product through gaps. This solves the problem that traditional products with threaded connections are prone to loosening of the threads after long-term use, resulting in gaps between the lampshade 1 and the connecting shell 2, and enhances the waterproof and dustproof effect of the product.

[0038] During the adjustment of the angle of the connecting shell 2, the connecting block 17 at the bottom of the connecting shell 2 is pushed to rotate on the outer wall of the rotating shaft 18. The arc surface of the outer wall of the rotating shaft 18 is used to push the second locking ball 20 into the connecting block 17, and the second spring 19 is compressed. When the connecting shell 2 is rotated to the appropriate angle, the elasticity of the second spring 19 is used to push the second locking ball 20 to engage with the groove on the outer wall of the rotating shaft 18, thereby fixing the angle of the connecting shell 2 and achieving a good application effect.
