Referring to fig. 1-4, in an embodiment of the present invention, a housing structure of a charger includes:

a lower case 100 including a lower case bottom plate 110 and a lower case wall 120 coupled to the lower case bottom plate 110;

an upper case 200 including an upper case bottom plate 210 and an upper case wall 220 coupled to the upper case bottom plate 210, the upper case being coupled to the lower case 100 to form a housing of the charger;

the sealing member 300 includes a sealing ring 310 and a blocking wall 320, which are connected to each other, the sealing ring 310 is clamped between the lower casing wall 120 and the upper casing wall 220, the blocking wall 320 abuts against the lower casing wall 120 and/or the upper casing wall 220, four corners of the sealing ring 310 are fixing lugs 311, fixing through holes 312 are provided on the fixing lugs 311, and the fixing through holes 312 are used for fixing nails passing through the casing structure.

The sealing member 300 can provide a waterproof effect between the lower case 100 and the upper case 200. In the sealing member 300, the sealing ring 310 mainly provides a sealing effect, and the blocking wall 320 may abut against the lower casing wall 120 and/or the upper casing wall 220 during the installation of the sealing member 300, so that the sealing member 300 is stably placed. If the fixing lug 311 is not present, the pressure applied to the sealing member 300 at the fixing nail is greater due to the existence of the fixing nail, so that the overall sealing and waterproof effect of the sealing member 300 is not good. In the embodiment, due to the existence of the fixing lug 311, the pressure applied to the sealing member 300 is relatively uniform, thereby providing a good waterproof sealing effect.

Referring to fig. 2, in one embodiment, at least two of the four fixing lugs 311 are provided with positioning through holes 313, and the positioning through holes 313 are used for aligning and matching with the positioning axes arranged at the free ends of the lower shell wall 120 far away from the lower shell bottom plate 110.

Before the lower shell 100 and the upper shell 200 are fixed by the fixing nail, the sealing element 300 is placed on the lower shell wall 120 of the lower shell 100, and the positioning through hole 313 is matched with the alignment shaft, so that the placing position of the sealing element 300 is accurate, the fixing nail can accurately penetrate through the fixing through hole 312, and the sealing element 300 can be well fixed.

Referring to fig. 4, in one embodiment, a first protruding ridge 221 is provided on a free end of the upper housing wall 220 away from the upper housing bottom plate 210 or a free end of the lower housing wall 120 away from the lower housing bottom plate 110, wherein the first protruding ridge 221 abuts against the sealing ring 310.

If the first protruding fillet 221 protrudes from the upper housing wall 220, the existence of the first protruding fillet 221 can make the sealing ring 310 have better clamping effect at the position of the first protruding fillet 221, that is, can provide better waterproof effect, compared with the situation that the sealing ring 310 is only clamped by the upper housing wall 220 and the lower housing wall 120.

In one embodiment, a second protruding fillet is provided on the free end of the upper housing wall 220 away from the upper housing bottom plate 210, and a third protruding fillet is provided on the free end of the lower housing wall 120 away from the lower housing bottom plate 110;

wherein the second and third protruding rims abut against the sealing member 300 and are horizontally offset.

The sealing member 300 is held only by the surfaces of the upper and

lower case walls

220 and 120, and the second and third protruding rims are horizontally disposed in a staggered manner, thereby providing two more waterproof effects.

Referring to fig. 3, in one embodiment, a support card 400 is further included, and the support card 400 is clamped between the lower housing wall 120 and the upper housing wall 220.

In the charger, several devices need to be installed and fixed in both the upper case 200 and the lower case 100, and some devices with larger volume are easily damaged by external impact. Through the setting of above-mentioned support card 400 for the great device of above-mentioned volume can support and lean on support card 400, has formed the support basis, has promoted the holistic fixed steadiness of charger.

Referring to fig. 3, in one embodiment, a middle portion of the support card 400 is bent and protruded toward the upper case 200 to form a support platform 410, and a surface of the support platform 410 near the upper case 200 is shaped like a platform.

The middle of the support card 400 is bent to form the support platform 410, so that the overall strength of the support card 400 is improved without increasing the thickness. The surface of the supporting platform 410 near the upper case 200 is flat, which is beneficial to providing a stable supporting effect.

Referring to fig. 3, in one embodiment, a plurality of protruding structures 420 are formed on the free end of the lower housing wall 120 away from the lower housing bottom plate 110, and the protruding structures 420 are matched with the supporting card 400 to limit the displacement of the supporting card 400.

The projection structure 420 does not reduce the strength of the lower housing wall 120 with respect to the fixing groove formed in the lower housing wall 120 to restrict the movement of the support card 400. Specifically, when the supporting card 400 is installed, the plurality of protruding structures 420 may guide the installation of the supporting card 400, and the protruding structures 420 may also be fixed to limit the fastening of the supporting card 400.

Referring to fig. 3, in one embodiment, a plurality of internal thread fixing seats 111 are provided on the lower shell bottom plate 110, and at least one fixing block 121 matched with the internal thread fixing seats 111 is provided on the inner side of the lower shell wall 120;

the circuit board of the charger is clamped between the internal thread fixing seat 111 and the fixing block 121 in the thickness direction.

The internal thread fixing seat 111 and the fixing block 121 are arranged at intervals in the vertical direction, so that the circuit board can be clamped and fixed in the internal thread fixing seat, and the clamping and fixing effect can provide a high-quality primary fixing effect in the alignment process of the circuit board. After the alignment of the circuit board is completed, the circuit board can be fixed on the female screw fixing seat 111 by screws.

An embodiment of the utility model provides a charger, including the shell structure of foretell charger.

The utility model provides a sealing element 300 can provide the water-proof effect between lower casing 100 and upper casing 200 for the shell structure and the charger of charger, and the barrier wall 320 can lean against lower casing wall 120 and/or upper casing wall 220 in the process of laying sealing element 300, thus make the sealing element 300 placement effect more stable; the fixing lug 311 makes the pressure applied to the whole sealing ring 310 more uniform, thereby providing a good waterproof sealing effect.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
