It should be noted that, the light shielding shell 122 is disposed on a side of the light guide plate 121 facing away from the indicator 40, the light shielding shell 122 is disposed at a portion of a side of the light guide plate 121 facing away from the indicator 40, and light emitted by the indicator 40 is emitted to the outside through a position of the light guide plate 121 not shielded by the light shielding shell 122, so that the light shielding shell 122 may be disposed in a corresponding shape according to actual requirements and in a specific position on a side of the light guide plate 121 facing away from the indicator 40, so that the light emitted by the indicator 40 may show a specific shape under the guidance of the light guide plate 121. Since one side of the light guide plate 121 is shielded by the light shielding case 122, when the light emitted from the indicator light 40 needs to display a specific shape, the light guide plate 121 does not need to be designed in a specific shape, which is helpful for improving the display uniformity of the light emitted from the indicator light 40.
Optionally, as shown in fig. 2, a clearance groove 1201 is formed in a side of the light guide plate 121 facing the indicator 40 in a recessed manner, and at least a portion of the indicator 40 may extend into the clearance groove 1201, so that light emitted by the indicator 40 can be better received by the light guide plate 121, which is beneficial to improving the light utilization rate of the indicator 40.
In one embodiment, referring to fig. 2 to 4, the light guide plate 121 includes a first light guide portion 1211 and a second light guide portion 1212, wherein the second light guide portion 1212 is annular and is disposed around an outer peripheral edge of the first light guide portion 1211; the second light guide portion 1212 is disposed at one end of the housing 11, the first light guide portion 1211 faces the indicator light 40, and the light shielding shell 122 is disposed at a side of the first light guide portion 1211 facing away from the indicator light 40. So set up for the light accessible second leaded light portion 1212 that pilot lamp 40 sent guides to the outside, and then makes the light that pilot lamp 40 sent realize annular through second leaded light portion 1212 and shows, like this, when leaded light subassembly 12 served as charging device's bottom bearing on the plane, the light that pilot lamp 40 sent can realize annular at the periphery of charging device bottom and show, helps improving charging device's convenience of use.
The division of the first light guide 1211 and the second light guide 1212 of the light guide plate 121 is determined by the light shielding case 122, specifically, a portion of the light guide plate 121 shielded by the light shielding case 122 is the first light guide 1211, and a portion of the light guide plate 121 not shielded by the light shielding case 122 is the second light guide 1212, so that the light emitted by the indicator light 40 can be displayed annularly without designing the light guide plate 121 in a specific shape, which is helpful for improving the display uniformity of the light emitted by the indicator light 40.
It should be noted that, the number of the indicator lamps 40 may be set to one, and the indicator lamp 40 faces the middle of the first light guide 1211, so that the first light guide 1211 guides the light of the indicator lamp 40 to the second light guide 1212, thereby implementing the ring-shaped display of the light emitted by the indicator lamp 40.
In one embodiment, referring to fig. 2 and fig. 5, a distance between a side of the charging element 20 facing away from the light guide element 12 and an inner wall of the housing 11 is in a range from 0.2mm to 0.6 mm; it can be understood that, in the distribution direction of the end shell 111 and the light guide assembly 12 of the housing 11, the distance between the inner wall of the end shell 111 and the side of the charging assembly 20 facing away from the light guide assembly 12 is in a range of 0.2mm to 0.6mm, that is, the gap of the spacing gap 30 in the distribution direction of the end shell 111 and the light guide assembly 12 of the housing 11 is in a range of 0.2mm to 0.6 mm. The arrangement is such that the clearance gap 30 is within a suitable clearance range, on one hand, the clearance range of the clearance gap 30 is not too small, that is, the clearance gap 30 has a certain width, so that the phenomenon that the charging device is locally overheated due to the fact that heat emitted by the charging assembly 20 is directly conducted to the position, close to the charging slot 101, of the housing 11 can be effectively prevented; on the other hand, the gap range of the spacing gap 30 is not too large, so that the charging assembly 20 can charge the to-be-charged member outside the housing 11, and the space utilization rate in the housing 11 can be improved on the basis of alleviating the problem of local overheating, thereby being beneficial to reducing the size of the charging device.
Optionally, a gap between a side of the charging assembly 20 facing away from the light guide assembly 12 and an inner wall of the housing 11 is 0.4 mm.
In one embodiment, referring to fig. 1 and fig. 2, the housing 11 is filled with waterproof heat-conducting glue, and it can be understood that the waterproof heat-conducting glue is filled between the inner wall of the housing 11 and the charging assembly 20; the waterproof thermal conductive adhesive covers the charging assembly 20 and fills the space gap 30. The indicator light 40 is disposed on one side of the charging assembly 20 facing away from the space gap 30, and extends away from the charging assembly 20, and one end of the indicator light 40 facing away from the charging assembly 20 is exposed to the outside of the waterproof heat-conducting adhesive and faces the light-guiding assembly 12.
It should be noted that, in the related art, when the charging device is designed to be waterproof, the indicator light 40 on the charging device is prone to display non-uniformity under the influence of the waterproof structure, and thus, it is difficult for the charging device to be compatible with both waterproof and the advantage of uniform display of the indicator light 40. According to the charging device provided by the embodiment of the application, the gap 30 is formed between the charging assembly 20 and the inner wall of the housing 11 at intervals, and the arrangement of the gap 30 can reduce the heat transfer speed, so that the heat generated by the charging assembly 20 is not directly conducted to the position of the housing 11 corresponding to the charging assembly 20; waterproof heat-conducting glue covers the charging assembly 20, and fills in the space gap 30, like this, space gap 30 and waterproof heat-conducting glue's setting for the heat that the charging assembly 20 produced when charging is unlikely to direct conduction to the casing 11 be close to the position of the charging assembly 20, but transmit each position to casing 11 under waterproof heat-conducting glue's conduction, so can slow down charging device better and produce local overheated problem when charging, thereby can slow down local overheated lead to wait to charge piece or charging device damage, scald user's problem. The waterproof heat-conducting glue is encapsulated in the shell 11 and covers the charging assembly 20, so that the waterproof heat-conducting glue can well realize the waterproof effect of the charging assembly 20, so that the charging assembly 20 can be isolated from the external water source under the protection of the waterproof heat-conducting glue, and, one end of the indicator light 40, which faces away from the charging assembly 20, is exposed outside the waterproof heat-conducting glue, and faces the light guide assembly 12, so that the light emitted from the indicator light 40 can be well emitted to the light guide member 12, and the light guide member 12 can guide the light emitted from the indicator light 40 to the outside of the charging device, the waterproof heat-conducting glue is distributed at intervals with the light guide assembly 12, so that the arrangement of the waterproof heat-conducting glue does not affect the light guiding function of the light guide assembly 12 and the display function of the indicator light 40, with such an arrangement, the light guide assembly 12 has a better light guiding effect, which is helpful for making the indicator light 40 have better display uniformity.
