DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0034] like Figure 1 , Figure 2As shown, this embodiment proposes that the present application provides a waterproof headlight that can be tied to a bicycle or other vehicle to provide lighting or night light reminders. The waterproof headlight of this embodiment mainly includes: a bottom shell 100, an outer cover 200, and an induction welding coil 300. The bottom shell 100 has an open side; specifically, the bottom shell 100 has a bottom plate 110 of a certain length. For the convenience of structural description, the direction of the longer side of the bottom plate 110 is the length direction, and the direction of the shorter side is the width direction. A front end plate 120 and a rear end plate 130 are respectively arranged at both ends of the length direction of the bottom plate 110. The front end plate 120 and the rear end plate 130 can be arc-shaped plates. The other sides of the bottom shell 100 formed by the front end plate 120, the rear end plate 130 and the bottom plate 110 are all open to form an open side, and the direction of the open side is the front side. The outer cover 200 is connected to the bottom shell 100 and covers the open side. An installation space is formed between the outer cover 200 and the bottom shell 100. The installation space is used to set the light-emitting device 400. Specifically, the outer cover 200 adopts an arc-shaped outer cover 200. The front and rear ends of the arc-shaped outer cover 200 are respectively matched and connected with the front end plate 120 and the rear end plate 130 at the front and rear ends. The two sides in the width direction are connected to the bottom plate 110, so that the entire front side of the outer cover 200 forms an arc surface. The entire arc surface can be used as a light-transmitting surface, so that the light emitted by the light-emitting device 400 is emitted through the light-transmitting surface. The use of the arc surface for light transmission increases the transmission angle of light, makes the lighting area wider, and the illumination range is larger when lighting at night, providing a better riding experience for cyclists riding at night.

[0035] like Figure 1 , Figure 6 , Figure 8 As shown, the induction welding coil 300 is arranged at the connection between the bottom shell 100 and the outer cover 200, and a full circle of the induction welding coil 300 is arranged at the edges of the bottom shell 100, so that the connection between the bottom shell 100 and the outer cover 200 is completely covered by the induction welding coil 300. The edges of the bottom shell 100 and the outer cover 200 are welded and fixed by induction welding, and the full circle of the induction welding coil 300 welds the edges in a full circle during the induction welding process, so that the bottom shell 100 and the outer cover 200 are fixed more firmly, and the full circle of the induction welding coil 300 is used to seal the full circle of the connection by induction welding, and no matching gap is generated at the connection, so that the sealing performance is better, and water vapor will not enter the installation space from the connection, meeting higher waterproof requirements.

[0036] The waterproof car lamp proposed in this embodiment is provided with an induction welding coil 300 at the connection between the bottom shell 100 and the outer cover 200, so that the outer cover 200 and the bottom shell 100 are welded by induction welding, so that the bottom shell 100 and the outer cover 200 are fixed, and the connection can be stably sealed, so that the waterproof level reaches IPX8 level. An installation space is formed between the outer cover 200 and the bottom shell 100 fixed by induction welding, and the light-emitting device 400 is arranged in the installation space, so that the light-emitting device 400 is powered on and emits light in the waterproof installation space to provide stable lighting. Moreover, the fixing method of induction welding replaces the traditional screw fixing process, thereby improving the assembly efficiency.

[0037] like Figure 1 , Figure 2 As shown, further, a limiting groove 140 is provided at the edge of the bottom shell 100 in this embodiment, and the limiting groove 140 can be provided around the edges of the entire bottom shell 100, or can be provided at intervals of multiple sections. The limiting groove 140 is mainly used to install the induction welding coil 300, so that the induction welding coil 300 is stably limited at the edge position of the bottom shell 100 and surrounds the edge of the bottom shell 100. An outer clamping platform 210 is provided around the outer cover 200, and the outer clamping platform 210 is provided in a matching manner with the limiting groove 140. It is distributed around the edges of the outer cover 200, and can be provided continuously or at intervals of multiple sections. The induction welding coil 300 is provided in the limiting groove 140, and the outer cover 200 is covered, so that the outer clamping platform 210 is embedded in the limiting groove 140, and then the induction welding is performed. First, the outer clamping platform 210 is provided with the limiting groove 140 for matching and limiting, so that the outer cover 200 can be accurately installed at the predetermined position of the bottom shell 100, and the position is not easily deviated during the assembly process, which is convenient for assembly. Secondly, the induction welding coil 300 in the limiting groove 140 is pressed down by the external clamping table 210 so that the induction welding coil 300 can be evenly expanded in the limiting groove 140. During the induction welding process, the welding amount of the entire edge connection between the outer cover 200 and the bottom shell 100 is uniform, thereby ensuring the welding quality.

[0038] like Figure 1 , Figure 2 As shown, further, the limiting groove 140 in this embodiment specifically includes: arc segments 141 located at both ends of the length direction and length segments 143 located at both ends of the width direction. Figure 2 , Figure 3As shown, a limiting step 142 is provided on the inner wall of the bottom shell 100, and the limiting step 142 is located between the end of the arc segment 141 and the end of the length segment 143, so that the length segment 143 is separated from the arc segment 141. When the induction welding coil 300 is placed in the limiting groove 140, the induction welding coil 300 can be stably limited in both the arc segment 141 and the length segment 143. At the transition position between the arc segment 141 and the length segment 143, the induction welding coil 300 is lifted up by the limiting step 142, so that the induction welding coil 300 is bent at the limiting step 142, so that the induction welding coil 300 can smoothly transition from the arc segment 141 to the length segment 143. If the arc segment 141 and the length segment 143 are directly connected without using the limiting step 142, the limiting groove 140 will change direction at the transition position, so that not only the outer clamping table 210 that matches there cannot be buckled in, making it difficult for the induction welding coil 300 to weld the outer clamping table 210, but also if the limiting groove 140 is used at the transition position, the depth of the limiting groove 140 will vary greatly, which will cause the induction welding coil 300 to bulge at some positions and concave at other positions at the transition position between the arc segment 141 and the length segment 143, thereby making it impossible to ensure the welding quality. Therefore, through the limiting step 142, one end of the limiting step 142 is connected to the inner wall of the end of the arc segment 141, and the other end is connected to the inner wall of the end of the length segment 143, so that the induction welding coil 300 is smoothly bent on the limiting step 142, ensuring the welding quality.

[0039] like Figure 2 , Figure 4 As shown, correspondingly, the two ends of the width direction of the outer clamping platform 210 matched with the arc segment 141 are provided with limiting bosses 211, that is, the ends of the outer clamping platform 210 located on the front and rear sides of the outer cover 200 form limiting bosses 211. The limiting bosses 211 are matched with the limiting steps 142 to limit the relative positions of the bottom shell 100 and the outer cover 200. By setting the limiting bosses 211, firstly, the limiting bosses 211 can squeeze the induction welding coil 300 on the limiting steps 142 to avoid the displacement of the induction welding coil 300 during the welding process, thereby ensuring the stability of the induction welding process. Secondly, the limiting bosses 211 can be matched with the limiting bosses 211 to form a limiting match. By supporting the limiting bosses 211 with the limiting steps 142 at the four corner positions, the position accuracy of the outer cover 200 and the bottom shell 100 during the installation process is ensured, which is convenient for assembly.

[0040] like Figure 2 , Figure 4As shown, further, the width of the limiting boss 211 gradually increases in the direction away from the outer card platform 210. Specifically, the closer the limiting boss 211 is to the end of the outer card platform 210, the greater the width. Since the limiting step 142 is connected to the lower end of the arc segment 141, the inner wall of the arc segment 141 is extended outward by a certain length by means of the surface of the limiting step 142. Therefore, the end of the limiting boss 211 is set to be relatively wide, which can match the inner wall surface extending from the end of the arc segment 141, thereby improving the support stability of the limiting step 142 and the limiting boss 211, and making the connection between the outer cover 200 and the bottom shell 100 more stable.

[0041] like Figure 5 , Figure 6 As shown, further, at least one of the inner walls on the two opposite sides of the arc segment 141 is tilted so that the opening width of the arc segment 141 is greater than the groove bottom width of the arc segment 141. In this way, the groove of the arc segment 141 can form a bell mouth, and when the outer cover 200 is installed on the bottom shell 100, the opening is large, which facilitates the insertion of the outer card table 210 into the limiting groove 140, and facilitates assembly.

[0042] like Figure 6 , Figure 8 As shown, further, an outer baffle plate 150 is formed on the outer side of the limiting groove 140, and the inner wall of the outer baffle plate 150 facing the installation space serves as the inner wall of the limiting groove 140. The edge sealing structure of the entire headlight adopts different forms according to different positions;

[0043] like Figure 5 , Figure 6 As shown, the closed structure outside the arc segment 141 is directly sealed by the outer baffle 150, that is, the outer clamping platform 210 is spaced apart from the outer edge of the bottom shell 100 to form an end face step 220; the outer baffle 150 outside the arc segment 141 is arranged inside the end face step 220. The outer surface of the outer baffle 150 serves as the exposed surface of the front and rear ends of the lamp, so that the two side walls of the front and rear end faces of the lamp are relatively complete and the overall appearance is relatively good.

[0044] like Figure 7 , Figure 8As shown, the closed structure outside the length section 143 adopts a hidden edge sealing, specifically, an outer edge sealing plate 230 is provided on the outer cover 200, and the outer edge sealing plate 230 is located outside the length section 143. An outer card slot 231 is formed between the outer edge sealing plate 230 and the outer card platform 210, and the outer card slot 231 is used to clamp the outer baffle 150 of the bottom shell 100. The outer edge sealing plate 230 is an integrally formed part of the outer cover 200, and the outer baffles 150 on both sides of the width direction are wrapped in the outer card slot 231 by the outer edge sealing plate 230, so that the outer edge sealing plate 230 is used as the exposed surface in the width direction of the lamp, so that no connection gap can be seen on the side of the entire outer cover 200, and the hidden edge sealing is realized, the integrity is better, and the appearance is better.

[0045] like Figure 1 , Figure 2 , Figure 3 As shown, further, the induction welding coil 300 in this embodiment can be a stainless steel coil. Induction welding is a non-contact heating welding technology that uses a high-frequency electromagnetic field to induce eddy currents on the stainless steel coil, causing the stainless steel coil to be subjected to a thermal effect, thereby achieving the purpose of welding the bottom shell 100 and the outer cover 200. Induction welding using a stainless steel coil is simple to operate, highly efficient, precisely controlled, and pollution-free, which can improve assembly efficiency.

[0046] like Figure 1 , Figure 2 As shown, further, hooks 240 are provided on both sides of the width direction of the outer cover 200 of this embodiment, and the hooks 240 are used to connect the elastic ring and fix it to the frame. In the specific structure, the hook 240 is arranged at a position of the outer cover 200 close to the bottom shell 100, and is integrally formed with the outer cover 200. The opening of the hook 240 is located on the front side (the side away from the bottom shell 100). When in use, one end of the elastic ring is hooked to the hook 240 on one side, and the other end is hooked to the hook 240 on the other side after passing around the frame. Since the elastic ring is elastic, the waterproof car light can be installed on the bicycle by stretching the elastic ring to hang on the hooks 240 on both sides.

[0047] In summary, a waterproof headlight in the present application is welded between the outer cover 200 and the bottom shell 100 by induction welding, so that the bottom shell 100 and the outer cover 200 are fixed, and the connection can be stably sealed, so that the waterproof level reaches IPX8. Moreover, the fixing method of induction welding replaces the traditional screw fixing process to improve the assembly efficiency. The use of curved surfaces for light transmission increases the transmission angle of light, making the lighting area wider, and the illumination range during nighttime lighting is larger, providing a better user experience for cyclists riding at night. The connection method of the hook 240 and the elastic ring is adopted to achieve convenient installation with the frame and facilitate disassembly from the bicycle.
