[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] refer to Figure 1 As shown, the circular dual-port USB charger provided by the present invention includes: a shell and a charger module 13 installed in the shell. The charger module 13 is provided with two charging interfaces 5 extending to the outside of the shell in parallel. The outside of the two charging interfaces 5 is provided with a waterproof cover 1 covered on the shell. The waterproof cover 1 is provided with a connector that is detachably connected to the shell. When the waterproof cover 1 is buckled with the shell, a waterproof area is formed to waterproof the two charging interfaces 5.

[0022] Combine Figure 1 and Figure 3-4 As shown, the shell includes a mounting base 8 and a lamp board 4. A storage compartment for accommodating a charger module 13 is formed in the mounting base 8. Slots 14 for plugging in the charger module 13 are provided on the inner walls on both sides of the storage compartment. The lamp board 4 is installed at the end of the storage compartment, and two charging interfaces 5 are both installed on the lamp board 4. A retaining ring 6 integrally formed with the clamp 11 is provided on the outer periphery of the mounting base 8.

[0023] Combine Figure 2-4 As shown, the end of the mounting base 8 away from the lamp board 4 is also provided with a power supply line for supplying power to the charger module 13, and the power supply line is provided with a line card 12 passing through the end of the mounting base 8 (the power supply line is not drawn in the figure).

[0024] As described above, when using the housing, charger module 13, charging interface 5 and waterproof cover 1 provided by the present invention, wherein:

[0025] The mounting base 8 is made of PA6+20% GF to ensure the mechanical strength of the shell. At the same time, the characteristics of PA6 itself adapt to the use conditions of the product as a leaking part. The front section of the mounting base 8 is made into two grooves for the installation of the waterproof cover 1; the inside is made into a glue dripping groove for glue storage; the inner side positioning column determines the installation direction of the light board 4, which plays a fool-proof role; the tail is opened with a wire hole and a wire card slot; the length and width of the product board and the height of the original parts on the board determine the inner diameter and length of the circular mounting base 8; the width of the slot 14 is determined by the thickness of the circuit board (the positioning column, glue dripping groove, wire hole, wire card slot, etc. are all marked in the figure). The light board 4 is made of PC, which has the characteristics of transparency and light transmission.

[0026] The surface of the light board 4 is sprayed with black paint, and the translucent light strip and charging logo are laser-engraved. The light strip illuminates during charging. The edge has positioning grooves that mate with the outer shell positioning posts. The bottom surface is reinforced to increase the contact area between the light board 4 and the glue. The interior is designed with interface installation guide grooves for the A+C ports, which also serve as a limiter for the interface (positioning posts, glue drip grooves, wire holes, and slots are marked in the figure).

[0027] The material of wire clip 12 is NR, with a hardness of 45-50HA. The front section is rounded to ensure easy installation while preventing easy withdrawal. The middle is designed with a boss inner diameter gradient wire hole. The large diameter wire hole side is convenient for threading, and the small hole side ensures sealing with the wiring harness.

[0028] The waterproof cover 1 is made of NBR with an anti-ozonant additive, which not only improves the weather resistance of the waterproof cover 1 but also has the characteristics of NBR itself; the cover is designed with an inverted structure to enhance the stability and waterproof performance of the waterproof cover 1; a boss is added to the front of the cover to facilitate the opening and closing of the cover; and the exterior surface is marked with USB and charging lightning logo fonts.

[0029] The material of the fixed ring seat 7 is PA6+20% GF. The front face is designed with a linearly distributed annular boss in a toothed structure to increase the fastening force of the fixed ring seat 7; the outer surface reinforcement ribs increase the strength of the fixed ring seat 7 to prevent it from breaking during the fastening process; the inner wall is made into an outer shell with a thread, and the thread depth is about three-quarters of the sleeve depth. The extended thread serves to increase the strength of the fixed ring.

[0030] The two charging ports 5 are Type-A and Type-C respectively.

[0031] Further, in order to facilitate the detachable installation of the waterproof cover 1 on the housing, refer to Figure 1-4 As shown, the connecting member includes a connecting ring 3 integrally formed with the waterproof cover 1, the connecting ring 3 being sleeved on the mounting seat 8, and a flexible plastic belt 2 for bending is provided at least partially between the connecting ring 3 and the waterproof cover 1. A fixing ring seat 7 is detachably provided on the outer periphery of the mounting seat 8, and a mounting area for accommodating the connecting ring 3 is formed between the fixing ring seat 7 and the retaining ring 6. An externally threaded seat 15 is provided on the outer periphery of the mounting seat 8 to abut against the retaining ring 6, and the fixing ring seat 7 is screwed onto the externally threaded seat 15. An anti-fouling structure is designed and installed on the inner side of the connecting ring 3 to ensure that the waterproof cover 1 is installed on the C-port side. When the connecting ring 3 is between the retaining ring 6 and the fixing ring seat 7, the fixing ring seat 7 is allowed to rotate on the externally threaded seat 15 toward the retaining ring 6, thereby clamping the connecting ring 3 between the retaining ring 6 and the fixing ring seat 7, thereby facilitating the detachable installation of the waterproof cover 1 on the housing. At the same time, the flexible plastic belt 2 facilitates the buckling of the waterproof cover 1 to the end of the housing.

[0032] In this utility model, combined with Figure 1As shown, a clamping seat 11 for fixing is provided on one side of the shell of this embodiment. A C-shaped clamping groove 10 for clamping is opened on the clamping seat 11. A fastening bolt 9 for adjusting the size of the notch of the C-shaped clamping groove 10 is provided on the clamping seat 11.

[0033] As mentioned above, when using the clamp seat 11 provided by the utility model, the material of the clamp seat 11 is PA6+20% GF, and the structure is divided into two parts, the upper part is the installation shell, and the lower structure includes a clamping part with a C-shaped clamp groove 10 and a fastening bolt 9, the fastening bolt 9 is composed of an M4 screw and an embedded nut, and an anti-slip rubber pad is provided in the C-shaped clamp groove 10 for anti-slip; the fastening bolt 9 is used to fasten the clamp seat 11 to the handle tube to realize the installation of the equipment, and the embedded nut is used to facilitate installation; the anti-slip rubber pad prevents the overall product from displacement to increase stability and also plays a shock-absorbing role.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
