[0002] With the rapid adoption of electric vehicles, demand for supporting mobile charging equipment is also growing rapidly. Waterproofing is crucial for charging equipment. Existing mobile charging equipment primarily utilizes external waterproof seals, but this sealant performance degrades significantly during use, significantly impacting the lifespan and safety of the equipment. Utility Model Content

[0003] Based on this, it is necessary to provide an electronic box and a charging device to address the problem of insufficient sealing life of the charging device.

[0004] An electronic box, comprising:

[0005] A housing, wherein a threading hole is provided on a side wall of the housing, the housing has a sealed inner wall, and a first sealing rib is provided on the sealed inner wall;

[0006] A cable, the cable being passed through the threading hole;

[0007] a sealing ring, the sealing ring being sleeved on the cable and located in the housing; and

[0008] A sealing pressing piece is used to press the sealing ring onto the sealing inner wall so that the sealing ring is pressed onto the first sealing rib at least along the axial direction of the cable.

[0009] In the present invention, the first sealing rib is spaced apart from the cable.

[0010] The utility model further provides a second sealing rib on the sealing inner wall, the first sealing rib and the cable are spaced apart from the second sealing rib, and the sealing ring is squeezed on the second sealing rib at least along the axial direction of the cable.

[0011] In the utility model, in the direction in which the sealing pressure piece points to the threading hole, the sealing inner wall is configured to be constricted, so that the sealing inner wall can squeeze the sealing ring onto the cable at least along the radial direction of the cable.

[0012] The first sealing rib of the utility model extends along the axial direction of the cable, and the first sealing rib has a sealing end surface at one end close to the sealing pressure piece. The sealing ring is pressed on the sealing end surface along the axial direction of the cable. The area of ​​the sealing end surface is S, and the contact area between the sealing end surface and the sealing ring is not less than

[0013] The electronic box of the present invention further comprises a wire locking seat, which is detachably mounted in the housing, and the cable is mounted on the wire locking seat.

[0014] The cable lock seat of the utility model is provided with anti-slip teeth, and the cable is squeezed on the anti-slip teeth.

[0015] The electronic box of the present invention also includes a lamp assembly, which includes an isolation seat, a first circuit board and at least two indicator lights. The indicator lights are electrically connected to the first circuit board. At least two isolation holes are spaced apart on the isolation seat. The isolation seat is installed on the first circuit board so that at most one indicator light is provided in each isolation hole.

[0039] Example:

[0040] This embodiment provides a charging device, including an electronic box. Figure 1-Figure 3 and Figure 5 The electronic box includes a shell 1, a cable 2, a sealing ring 3, a sealing pressure piece 4 and a second circuit board 8.

[0041] A wire hole 11 is provided on the side wall of the housing 1 and communicates with the interior of the housing 1. The cable 2 is threaded through the hole 11, with one end of the cable 2 located inside the housing 1 and the other end outside. A second circuit board 8 is mounted within the housing 1 and electrically connected to the end of the cable 2 located within the housing 1. A sealing ring 3 is mounted on the cable 2 and located within the housing 1 to provide a waterproof seal for the wire hole 11.

[0042] The housing 1 has a sealed inner wall 12, and a first sealing rib 121 is provided on the sealed inner wall 12. The sealing pressing member 4 is also located in the housing 1. The sealing pressing member 4 presses the sealing ring 3 against the sealed inner wall 12 and the first sealing rib 121 simultaneously, so that the sealing ring 3 has a sufficient waterproof sealing effect.

[0043] In this embodiment, the sealing pressing member 4 is plate-shaped, the cable 2 is passed through the middle of the sealing pressing member 4 , and the sealing pressing member 4 can move axially along the cable 2 .

[0044] See also Figure 2 In this embodiment, before the sealing pressure piece 4 squeezes the sealing ring 3 along the axial direction of the cable 2, the deformation of the sealing ring 3 is very small or there is no deformation, and no part of the sealing ring 3 is located between the sealing pressure piece 4 and the first sealing rib 121, or only a small part of the sealing ring 3 is located between the sealing pressure piece 4 and the first sealing rib 121.

[0045] See also Figure 3 and Figure 4When the sealing member 4 squeezes the sealing ring 3 axially along the cable 2, the sealing ring 3 undergoes significant deformation. Not only does the sealing ring 3 maintain a good fit with the sealing inner wall 12, but a portion of the sealing ring 3 also enters between the sealing member 4 and the first sealing rib 121. As a result, the sealing ring 3 exerts pressure on the first sealing rib 121 in the axial direction of the cable 2. Therefore, the first sealing rib 121 increases the degree of deformation of the sealing ring 3, allowing the sealing ring 3 to better fill the gap between the sealing inner wall 12 and the cable 2, thereby improving the waterproof seal at the threading hole 11.

[0046] It is not difficult to understand that since the sealing ring 3 is located inside the shell 1, the sealing ring 3 is protected by the shell 1. Accordingly, the sealing ring 3 can provide a more long-term and stable waterproof seal for the threading hole 11, thereby improving the safety and service life of the electronic box and the charging device.

[0047] This embodiment provides a detailed structure of the cooperation between the first sealing rib 121 and the sealing ring 3, see Figure 4 The first sealing rib 121 extends axially along the cable 2 , and one end of the first sealing rib 121 close to the sealing pressing piece 4 has a sealing end surface 1211 , and the sealing ring 3 is pressed on the sealing end surface 1211 along the axial direction of the cable 2 .

[0048] Preferably, the area of ​​the sealing end surface 1211 is S, and the contact area between the sealing end surface 1211 and the sealing ring 3 is not less than To ensure that the sealing ring 3 has generated sufficient deformation.

[0049] In order to prevent the first sealing rib 121 from damaging the cable 2 , the first sealing rib 121 and the cable 2 are generally spaced apart.

[0050] In this embodiment, the sealing inner wall 12 is an arc surface. In the direction of the sealing pressure piece 4 pointing to the threading hole 11, the sealing inner wall 12 is configured to be constricted. Therefore, when the sealing inner wall 12 squeezes the sealing ring 3, a component force along the radial direction of the cable 2 is generated, and the contact between the sealing ring 3 and the cable 2 is closer, which also improves the waterproof seal at the threading hole 11.

[0051] Also as a preferred embodiment, a second sealing rib 122 is provided on the sealing inner wall 12. When the sealing pressing member 4 compresses the sealing ring 3, the sealing ring 3 is also pressed against the second sealing rib 122 at least along the axial direction of the cable 2. The second sealing rib 122 functions similarly to the first sealing rib 121, both of which can increase the deformation of the sealing ring 3.

[0052] In this embodiment, the second sealing rib 122 is located on the sealing inner wall 12 between the first sealing rib 121 and the threading hole 11, and the first sealing rib 121 and the second sealing rib 122 are spaced apart. During the deformation of the sealing ring 3, the second sealing rib 122 can better guide the deformed portion of the sealing ring 3 into the gap between the cable 2 and the sealing inner wall 12, thereby further optimizing the sealing effect of the sealing ring 3.

[0053] Likewise, in order to prevent damage to the cable 2 , the second sealing rib 122 and the cable 2 are generally spaced apart.

[0054] The electronic box also includes a wire lock seat 5, which is provided with a locking cover 52. The wire lock seat 5 is mounted on the inner wall of the housing 1. The locking cover 52 locks the cable 2 on the wire lock seat 5 to reduce the shaking of the cable 2 in the housing 1 and improve the electrical connection stability between the cable 2 and the second circuit board 8. Figure 6 The cable lock seat 5 is provided with anti-slip teeth 51, and the locking cover 52 presses the cable 2 against the anti-slip teeth 51, reducing the occurrence of cable 2 slipping and improving the locking effect of the locking cover 52 on the cable 2. In addition, the cable lock seat 5 is detachably mounted on the inner wall of the housing 1, so the inner wall of the housing 1 can be installed with cable lock seats 5 of different specifications to match cables 2 of different sizes.

[0055] See also Figure 7-Figure 9 The electronic box further includes a lamp assembly 6 and an upper cover 9 . The lamp assembly 6 is mounted on the upper cover 9 . The upper cover 9 is closed on the housing 1 to set the lamp assembly 6 inside the housing 1 .

[0056] The lamp assembly 6 includes an isolation base 61, a first circuit board 62, and at least two indicator lights 63. The indicator lights 63 are electrically connected to the first circuit board 62. The isolation base 61 is provided with at least two isolation holes 611 spaced apart. The isolation base 61 is snapped onto the first circuit board 62, so that at most one indicator light 63 is positioned within each isolation hole 611. The propagation direction of light emitted by each indicator light 63 is restricted by the sidewalls of the isolation hole 611 in which it resides, thereby reducing interference between the light emitted by different indicator lights 63.

[0057] See also Figure 7 and Figure 10The electronic box also includes a back plate 7, which is mounted on the outer wall of the shell 1. A hanging hole 71 is provided on the back plate 7. In this embodiment, the hanging hole 71 is a gourd hole. The outer wall of the shell 1 is recessed to form an avoidance groove 13, which is connected to the hanging hole 71. The hanging screw 100 is fixed horizontally on the wall, and the head of the hanging screw 100 can enter the avoidance groove 13 through the hanging hole 71. Then, under the action of gravity, the edge of the hanging hole 71 can be supported on the rod of the hanging screw 100, and the shell 1 avoids the head of the hanging screw 100 through the avoidance groove 13, and the electronic box is hung on the wall through the hanging screw 100.

[0058] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
