Description

Technical Field

[0001] The present application relates to the field of lampshade mounting structures, and in particular to a waterproof structure of a curved step glass cover of a headlamp. Background Art

[0002] Headlights are installed on both sides of a vehicle's head, providing illumination for driving at night or in dark environments, ensuring driving safety. Traditionally, the glass shade is installed by attaching it to the frame at the end of the lamp housing, so that the sides of the glass shade abut against the frame. Blocking pieces are provided on both sides of the frame, which abut against the glass shade to restrict its movement, completing the installation.

[0003] In the above structure, the glass lampshade and the frame on the lampshade are sealed by directly pressing against each other, which has a limited sealing effect and is prone to moisture infiltration, thereby affecting the service life of the lamp body. Utility Model Content

[0004] In order to enhance the sealing effect at the installation point of the glass cover, the present application provides a waterproof structure of a curved step glass cover for a headlamp.

[0005] The present application provides a waterproof structure for a curved step glass cover of a headlamp using the following technical solutions:

[0006] A waterproof structure of a curved step glass mask for a headlamp comprises a lamp housing, a frame, a mask and a step. The frame is detachably connected to the lamp housing, the step is fixedly connected to the inner side of one end of the frame, a groove for accommodating the step is provided around the circumference of the mask, one side of the step abuts against the bottom wall of the groove, and the side of the mask away from the step abuts against the lamp housing.

[0007] By adopting the above technical solution, the steps and the grooves cooperate with each other, so that the contact between the mask and the frame can be made tighter, which helps to enhance the sealing and thus enhance the waterproof effect.

[0008] Optionally, a convex ring is fixedly connected to the inner side of the frame at one end away from the step, and a receiving groove for receiving the convex ring is provided on the lamp housing.

[0009] By adopting the above technical solution, the provision of the convex ring prolongs the path for moisture to penetrate into the interior, thereby helping to enhance the waterproof effect.

[0010] Optionally, the bottom wall of the groove and the step are bonded and fixed.

[0011] By adopting the above technical solution, during installation, glue is first applied to the bottom wall of the groove, and then the mask is installed, and the step on the frame and the bottom wall of the groove on the mask are abutted against each other. At this time, the step and the bottom wall of the groove can be bonded and fixed to fix the mask; then the frame is fixedly installed on the lamp housing, so that the lamp housing is tightly pressed against the other side of the mask, thereby completing the installation of the mask; therefore, the bonding and fixing between the groove and the step can, on the one hand, improve the stability of the mask after installation, and on the other hand, can play a pre-positioning effect after the mask is initially installed, thereby enhancing the abutment effect between the subsequently installed lamp housing and the mask.

[0012] Optionally, waterproof glue is filled between the step and the groove.

[0013] By adopting the above technical solution, the sealing performance of the gap between the step and the groove can be enhanced.

[0014] Optionally, a first inclined surface is provided on a side of the step away from the frame, and a second inclined surface matching the first inclined surface is provided on an inner wall of the groove.

[0015] By adopting the above technical solution, the first inclined surface and the second inclined surface abut against each other, so that the step and the groove abut more tightly, thereby further enhancing the sealing effect.

[0016] Optionally, a positioning column is provided on one side of the step close to the groove, and the positioning column is arranged along the sliding direction of the mask when it is installed. A positioning groove for inserting the positioning column is provided on the bottom wall of the groove.

[0017] By adopting the above technical solution, the mask can be positioned when it is installed. After the mask is installed, the lateral movement of the mask can be restricted, thereby enhancing the stability of the mask after installation.

[0018] Optionally, the end of the positioning column away from the step is arranged in a hemispherical shape.

[0019] By adopting the above technical solution, the end of the positioning column can be easily inserted into the positioning groove, thereby preventing the end of the positioning column from being stuck during the process of installing the mask.

[0020] Optionally, a plurality of water retaining rings are fixedly provided on the bottom wall of the groove, the water retaining rings are made of elastic material, and a water retaining groove for resisting against the water retaining rings is provided on the step.

[0021] By adopting the above technical solution, since the water retaining ring is elastic, it can be deformed when under pressure and tightly filled in the water retaining groove, thereby extending the path for water to penetrate and enhancing the waterproof effect.

[0022] Optionally, the cross section of the water retaining ring is trapezoidal.

[0023] By adopting the above technical solution, it is convenient to insert the water retaining ring into the water retaining groove.

[0024] Optionally, a gripping rod is fixedly connected to a side of the mask away from the step.

[0025] By adopting the above technical solution, when installing the mask on the frame, the mask can be held by holding the holding rod and then the mask is installed. Therefore, the setting of the holding rod makes it easy for the user to install the mask and avoids glue on the user's hands during the installation process.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The combination of the steps and the grooves can enhance the sealing effect between the mask and the frame, thereby enhancing waterproofness.

[0028] 2. The step and the shell are respectively pressed against both sides of the mask to fix the mask, thereby eliminating the baffle in the traditional structure, making the overall structure more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] Example 1

[0037] The embodiment of the present application discloses a waterproof structure of a curved step glass cover for a headlamp. Figure 1 、 Figure 2 and Figure 3The waterproof structure of the curved step glass mask of the headlamp includes a lamp housing 1, a frame 2 and a mask 3. The frame 2 is detachably connected to the lamp housing 1 by screws. A step 4 is fixedly connected to the inner side of the frame 2 away from the end of the lamp housing 1. The step 4 is provided with a circle, and the shape of the step 4 is adapted to the shape of the frame 2. A groove 31 whose shape is adapted to the step 4 is provided on the peripheral side of the top surface of the mask 3. After the mask 3 is installed, the bottom wall of the groove 31 can be abutted against the step 4, and the bottom wall of the mask 3 can be abutted against the lamp housing 1, thereby fixing the mask 3 between the frame 2 and the lamp housing 1, completing the installation of the mask 3. The step 4 and the groove 31 cooperate with each other and can be abutted more tightly, thereby enhancing the waterproof performance.

[0038] The step 4 and the groove 31 are bonded and fixed. During installation, first apply glue to the bottom wall of the groove 31, and then slide the mask 3 in so that the bottom wall of the groove 31 and the step 4 are against each other, thereby bonding and fixing the mask 3 to the step 4 at the end of the frame 2; then fix the frame 2 to the lamp housing 1 and make the lamp housing 1 and the mask 3 against each other.

[0039] Reference Figure 2 and Figure 3 Furthermore, the end surface of the step 4 and the groove 31 are coated with waterproof glue 5, thereby further reducing the possibility of water penetration and enhancing the waterproof effect.

[0040] A convex ring 21 is fixedly connected to the end of the frame 2 away from the step 4, and the convex ring 21 is located on the inner side of the frame 2; a receiving groove 11 adapted to the convex ring 21 is opened on the lamp housing 1, and the convex ring 21 is located in the receiving groove 11, thereby further extending the path for water penetration, thereby enhancing the waterproof effect.

[0041] A rubber pad 7 is also bonded and fixed to the lamp housing 1 on the side close to the face shield 3. The side of the rubber pad 7 away from the lamp housing 1 abuts against the bottom wall of the face shield 3. Therefore, after the frame 2 is fixed to the lamp housing 1 with screws, the rubber pad 7 is pressed tightly and deformed, making the rubber pad 7 and the face shield 3 fit more tightly, which helps to enhance waterproofness.

[0042] The implementation principle of Example 1 is as follows: Glue is applied to the bottom wall of groove 31, and then the mask 3 is slid in, so that the bottom wall of groove 31 abuts against the step 4 at the end of frame 2, thereby fixing the mask 3 to frame 2. Waterproof glue 5 is then applied to the gap between step 4 and groove 31. The frame 2 and lamp housing 1 are then aligned and fixed to the lamp housing 1 with screws. After the frame 2 is installed, the rubber pad 7 on the lamp housing 1 can be pressed against the bottom wall of the mask 3, completing the installation of the mask 3. The combination of the boss and groove 31 prolongs the path for water to penetrate, thereby enhancing the waterproof effect and helping to ensure the life of the lamp body.

[0043] Example 2

[0044] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that a first inclined surface 41 is provided on the end surface of the step 4 on the side away from the frame 2 in this embodiment. The first inclined surface 41 is provided on both sides of the step 4. The first inclined surface 41 is arranged along the length of the step 4, and the first inclined surfaces 41 on both sides of the step 4 have opposite inclinations. Correspondingly, a second inclined surface 311 is provided on the inner wall of the groove 31, with the same inclination as the first inclined surface 41, and the second inclined surface 311 can abut against the first inclined surface 41. Therefore, after the mask 3 is installed, the first inclined surface 41 and the second inclined surface 311 can abut against each other, thereby enhancing the abutment between the step 4 and the groove 31 and helping to improve waterproofness.

[0045] One end of the step 4 is fixedly connected to a positioning post. There are four positioning posts, which are respectively arranged at the four corners of the step 4. The positioning posts are arranged along the sliding direction of the mask 3 when it is installed. Correspondingly, positioning grooves are provided at the four corners on the bottom wall of the groove 31. The length direction of the positioning grooves is adapted to the positioning posts. Therefore, after the mask 3 is installed, the positioning posts can be located in the positioning grooves, thereby limiting the movement of the mask 3 by limiting the positioning posts by the positioning grooves, thereby improving the stability of the mask 3 after installation. The end of the positioning post away from the step 4 is hemispherical, which makes it easy to insert the positioning post into the positioning groove, which helps to smoothly carry out the installation process.

[0046] A water retaining ring 6 is fixedly connected to the bottom wall of the groove 31, and the shape of the water retaining ring 6 is adapted to the groove 31. There are multiple water retaining rings 6, and they are evenly spaced. The water retaining rings 6 are made of elastic rubber material, and the cross-section of the water retaining ring 6 is trapezoidal. The bottom surface of the step 4 is provided with multiple water retaining grooves 42. The number of water retaining grooves 42 is the same as the number of water retaining rings 6, and each water retaining groove 42 corresponds to a water retaining ring 6. Therefore, after the mask 3 is installed, the water retaining ring 6 is pressed tightly into the corresponding water retaining groove 42, thereby further extending the path for water to penetrate and helping to enhance the waterproof effect.

[0047] In order to facilitate the installation of the mask 3, a gripping rod is fixedly connected to the bottom wall of the mask 3, and two gripping rods are provided, and are respectively located at both ends of the mask 3. Therefore, the provision of the gripping rod makes it easy for the user to pick up the mask 3, thereby facilitating the installation and removal of the mask 3.

[0048] The implementation principle of Example 2 is as follows: apply glue to the bottom wall of the groove 31, hold the holding rod, and then align the positioning groove on the mask 3 with the positioning column on the step 4; slide the mask 3 along the extension direction of the positioning column, and make the second inclined surface 311 on the groove 31 and the first inclined surface 41 on the step 4 abut against each other, so that the mask 3 is bonded and fixed to the step 4. Then apply waterproof glue 5 in the gap between the step 4 and the groove 31. Then fix the frame 2 to the lamp housing 1 with screws, and the rubber pad 7 on the lamp housing 1 presses against the bottom wall of the mask 3, thereby fixing the mask 3. At this time, the mask 3 is in a pressed state, and the water retaining ring 6 presses against the water retaining groove 42, thereby further extending the path for water to penetrate, thereby enhancing the waterproof effect.

[0049] The above are optional embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
