[0043] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0044] Please refer to the following: Figures 1 to 11The present application provides a description of a waterproof headlamp. The waterproof headlamp includes a housing 1, a battery housing 2, and a cover plate 3. The housing 1 has an opening on one side and a light-transmitting plate 11 on the other side. The battery housing 2 is inserted into the housing 1. The outer peripheral wall of the battery housing 2 contacts the inner peripheral wall of the housing 1, and a sealing structure is provided between the outer peripheral wall of the battery housing 2 and the inner peripheral wall of the housing 1. The outer side of the battery housing 2 has a pick-and-place opening, and the outer periphery of the battery housing 2 has an outer edge 21 that can contact the opening end of the housing 1. One side of the cover plate 3 has a sealing gasket 4, which covers the pick-and-place opening of the battery housing 2. The opening end of the housing 1 has several threaded holes, and the outer edge 21 and the cover plate 3 have through holes corresponding to the threaded holes, and are fixed by bolts. The cover plate 3 has an annular slot 31, and the sealing gasket 4 has a recessed portion recessed into the annular slot 31, with an insertion port 41 formed on the outer side of the recessed portion. A frame 22 that is inserted into the insertion port 41 is connected to the outer side of the battery housing 2.

[0045] The waterproof headlamp provided in this application, compared with the prior art, has a battery housing 2 that is independently set. The battery housing 2 is sealed to the outer shell 1 by a sealing structure, and the cover plate 3 is sealed to the battery housing 2 by a sealing gasket 4. This can improve the sealing performance of the connection between the battery housing 2 and the outer shell 1 and the connection between the battery housing 2 and the cover plate 3, and reduce the occurrence of water leakage. The insertion and cooperation between the frame 22 and the recessed part of the sealing gasket 4 can extend the water leakage path and further improve the waterproof performance.

[0046] The through hole on the cover plate 3 corresponding to the threaded hole of the outer shell 1 is a countersunk hole, and the bolt nut is located in the countersunk hole. Through the above arrangement, the bolt nut can be hidden inside the cover plate 3.

[0047] In some embodiments, such as Figures 1 to 11 As shown, the sealing structure includes several sealing rings 5, and the outer peripheral wall of the battery casing 2 has a placement groove 23 for placing the sealing rings 5; wherein, the sealing rings 5 ​​abut against the inner peripheral wall of the casing 1.

[0048] The placement groove 23 on the outer peripheral wall of the battery case 2 is an annular structure. The number of placement grooves 23 on the battery case 2 is not limited to one; there can be two or more. A sealing ring 5 is placed in each placement groove 23. When the battery case 2 is inserted into the outer casing 1, the sealing ring 5 in the placement groove 23 can press against the inner peripheral wall of the outer casing 1 and the bottom wall of the placement groove 23, thus sealing the outer peripheral wall of the battery case 2 and the inner peripheral wall of the outer casing 1.

[0049] In some embodiments, such as Figures 1 to 11As shown, the connection position between the outer edge 21 of the battery case 2 and the outer shell 1 has an annular sealing groove 12. An annular sealing frame 6 is fitted inside the annular sealing groove 12. The inner peripheral wall of the annular sealing frame 6 has an elastic layer to fit tightly against the annular sealing groove 12. The outer peripheral wall of the annular sealing frame 6 is coplanar with the outer peripheral wall of the outer shell 1. The outer peripheral wall of the annular sealing frame 6 has a wear-resistant layer.

[0050] The annular sealing groove 12 is located on the outer side of the outer shell 1. The annular sealing groove 12 is formed by the outer edge 21 of the battery shell 2 and the outer shell 1. During installation, the annular sealing frame 6 is first fitted onto the part of the annular sealing groove 12 and the outer shell 1, and then the battery shell 2 is inserted into the outer shell 1.

[0051] After the battery case 2 is inserted into place, an annular sealing groove 12 is formed between the outer edge 21 of the battery case 2 and the outer shell 1. The annular sealing frame 6 is confined within the annular sealing groove 12. Therefore, during normal use, the annular sealing frame 6 will not fall off the outer shell 1.

[0052] The elastic layer on the inner circumferential wall of the annular sealing frame 6 can fit tightly against the bottom wall of the annular sealing groove 12, thereby sealing the connection between the outer edge 21 of the battery case 2 and the outer shell 1, reducing the amount of water entering between the battery case 2 and the outer shell 1, and improving the waterproof performance.

[0053] In some embodiments, such as Figures 1 to 11 As shown, the battery casing 2 has a fixing component inside for fixing the charging power supply, and the bottom wall of the battery casing 2 has a cable hole for the cable to pass through; wherein, a sealing cylinder 24 is connected to the outer periphery of the cable hole inside the battery casing 2; after the cable passes through the cable hole, the sealing cylinder 24 is filled with sealant.

[0054] By setting a fixing component inside the battery housing 2, the rechargeable battery can be fixed in place. During normal use of the waterproof headlamp, the movement of the rechargeable battery inside the battery housing 2 can be limited, thus reducing the possibility of the rechargeable battery colliding inside the battery housing 2.

[0055] After the rechargeable battery cable passes through the cable hole, it can be sealed by filling the sealing cylinder 24 with sealant.

[0056] Sealants include epoxy resin potting compounds, silicone potting compounds, and polyurethane potting compounds. When using them, you can choose one of these sealants.

[0057] In some embodiments, such as Figures 1 to 11 As shown, the fixing component includes a U-shaped plate 25, the open end of which is connected to the bottom wall of the battery case 2 and forms a receiving space for placing the charging power supply.

[0058] The opening of the U-shaped plate 25 and the battery case 2 can be connected by bolts. Both sides of the opening of the U-shaped plate 25 have bent portions 251 with through holes. The bottom wall of the battery case 2 has threaded holes that align with the bent portions 251. The bent portions 251 and the bottom wall of the battery case 2 are connected by bolts.

[0059] After the U-shaped plate 25 is connected to the battery case 2, the U-shaped plate 25 can provide a certain pressure to the charging power supply to limit the sliding of the charging power supply inside the battery case 2. It should be noted that the pressure of the U-shaped plate 25 on the charging power supply will not cause the charging battery to deform, so it will not affect the use of the charging battery.

[0060] In some embodiments, such as Figures 1 to 11 As shown, a sealing sleeve 241 is provided inside the sealing cylinder 24. The sealing sleeve 241 is fitted onto the cable, and the length of the sealing sleeve 241 is less than the length of the sealing cylinder 24.

[0061] With the above configuration, one end of the sealing sleeve 241 is made of rigid material and is inserted into the cable hole; the other end of the sealing sleeve 241 is made of flexible material. After the cable passes through the sealing sleeve 241, the end of the flexible material of the sealing sleeve 241 is tied with a cable tie, so that the sealing sleeve 241 is tightly fitted with the cable at the end of the flexible material.

[0062] Then, epoxy resin potting compound is injected into the sealing cylinder 24. After the epoxy resin potting compound solidifies, the flexible end of the sealing sleeve 241 is located inside the epoxy resin potting compound, and the epoxy resin potting compound is fixedly connected to the sealing cylinder 24, which can improve the sealing performance.
