In this embodiment, referring to fig. 7, the first board 210 is provided with a sliding slot 212, the sliding slot 212 penetrates through the first board 210 and communicates with the space 201, and the sliding slot 212 may be exposed from a surface of the first board 210 away from the second board 230. The width of the sliding groove 212 should be smaller than the size of the light adjusting member 400 to prevent the light adjusting member 400 from coming out of the sliding groove 212. The protective case 100 may further include a toggle member for passing through the slide groove 212 and toggling the light adjusting member to slide, and the toggle member may be configured to be inserted into the slide groove 212. For example, the toggle member may be provided in the shape of a rod, an elongated bar, or the like. The toggle member may be separated from the light adjusting member 400, and in one embodiment, a surface of each light adjusting member 400 facing the first plate 210 may be provided with a groove, and the toggle member may be embedded in the groove after being inserted into the sliding groove 212, so that the light adjusting member 400 may be driven to move by moving the toggle member. In another embodiment, the toggle member may be made of a metal material, and a magnetic member is disposed on a surface of the light adjusting member 400 facing the first plate 210, and when the toggle member is close to the light adjusting member 400, the toggle member and the light adjusting member are attracted to each other, so that the purpose of driving the light adjusting member 400 to move is achieved by moving the toggle member. The benefit of this embodiment is that only one toggle member is needed to effect movement of all of the light adjusting members 400.

The toggle element may also be connected with the light adjusting elements 400 as a whole, for example, the toggle element may include a protrusion 410 disposed on each light adjusting element 400, and the protrusion 410 is disposed in the sliding slot 212 and may partially protrude from the surface of the first plate 210 away from the second plate 230. So that the user can directly operate the protrusion 410 to control the movement of the corresponding light adjusting member 400. For the convenience of the user, the protrusion 410 may be configured to have a smooth structure to improve the tactile sensation, for example, the portion of the protrusion 410 protruding from the first plate 210 may be configured to be in a point shape, so that the user may not feel uncomfortable when taking the protective shell.

In order to avoid the light-modulating element 400 blocking the first through hole 211, the protrusion 410 blocks the light entering the first through hole 211, in some embodiments, the protrusion 410 may be disposed at an edge of the light-modulating element 400, and when the light-modulating element 400 slides to block the first through hole 211, the protrusion 410 is located outside the first through hole 211, thereby preventing the protrusion 410 from blocking the light entering the first through hole 211.

The sliding groove 212 can reasonably set the length of the sliding groove 212 according to the number of the light adjusting pieces 400, and can reasonably arrange the extending direction of the sliding groove 212 according to the position of the first through hole 211, so that in the process that the dial piece drives the light adjusting pieces 400 to slide, a user can selectively move the required light adjusting pieces 400 to the first through hole 211, and each light adjusting piece 400 can be moved to the first through hole 211, thereby achieving the purpose of sealing the first through hole 211. For example, in the present embodiment, referring to fig. 7, the sliding slot 212 includes a first sliding slot 213 and a second sliding slot 214, the first sliding slot 213 and the second sliding slot 214 are connected to each other, the first sliding slot 213 extends along a first direction X, the second sliding slot 214 extends along a second direction Y, and the first direction X and the second direction Y are different directions. The advantage of this arrangement is that each light adjusting member 400 can slide in at least two different directions during the sliding process, so that each light adjusting member 400 can be moved to the first through hole 211 to seal the first through hole 211, and the light adjusting members 400 can be staggered.

In particular, in one embodiment, the first direction X and the second direction Y may be two directions perpendicular to each other. More specifically, the first direction X may be the same direction as the length direction of the first plate 210, and the second direction Y may be the same direction as the width direction of the first plate 210. It should be noted that the length direction and the width direction of the first plate 210 are the length direction and the width direction of the electronic device 10 adapted to the accommodating space 101.

It should be noted that, when there are a plurality of light-adjusting members 400, the light-adjusting members 400 may be disposed at intervals 201 in the interval 201, and the light-adjusting members 400 are disposed in a coplanar manner, so that any two light-adjusting members 400 do not interfere with each other, and a user can select a suitable light-adjusting member 400 conveniently. Of course, among the plurality of light adjusting members 400, some or all of the light adjusting members 400 may be stacked and separated from each other only when moved to the first through hole 211.

In order to facilitate the light adjusting elements 400 to slide conveniently in the space 201, the thickness of the space 201 may be slightly greater than the thickness of each light adjusting element 400, so that the light adjusting elements 400 may be ensured to slide in the space 201, and the first plate 210 and the second plate 230 may limit and guide the light adjusting elements 400, thereby avoiding the light adjusting elements 400 from being jammed during the sliding process. Illustratively, the thickness of the spacers 201 is 0.2mm to 1mm greater than the thickness of the filter. Under the condition of the distance, the light adjusting member 400 can maintain a good sliding performance, and when the light adjusting member 400 is not slid, a certain friction force is generated between the light adjusting member 400 and the first plate 210 and the second plate 230 to limit the movement of the light adjusting member 400, so that the light adjusting member 400 maintains the current position. The thickness of the space 201 is the distance between the first plate 210 and the second plate 230. The thickness of each light modulation member 400 may be the same or different, and is not limited herein.

Referring to fig. 4 and 8, to further avoid the light adjusting device 400 from being jammed during the sliding process. In some embodiments, the side of the second plate 230 facing the first plate 210 may be further provided with a guide rail 232, and the guide rail 232 may be only provided on the side of the second plate 230 facing the first plate 210. In some embodiments, the guide rail 232 may be a groove-like structure, and further may be disposed through the second plate 230. Every light adjusting part 400 is wide in order to set up with guide rail 232 complex reference column 420, and reference column 420 can imbed in the guide rail 232 with sliding, and when external force drive light adjusting part 400 slided, light adjusting part 400 can slide according to the extending direction of guide rail 232, and then more controllable control light adjusting part 400 removed, and the user of being convenient for removes light adjusting part 400 to required position. The guide rail 232 may also guide the movement of the light adjusting member 400, and regulate the movement track of each light adjusting member 400, so that the user can accurately and rapidly adjust the light adjusting member 400 with a required gear to move to the first through hole 211.

As shown in fig. 9, the positioning pillars 420 and the bumps 410 may be located on opposite sides of the light adjusting member 400, and may be disposed correspondingly, so that when the light adjusting member 400 moves to the first through hole 211, the bumps 410 and the positioning pillars 420 may be located outside the first through hole 211, and may not block the light entering the first through hole 211.

The guide rail 232 can be configured in various structures as desired, for example, the guide rail 232 can be configured to cooperate with the sliding groove 212. As an implementation manner, in the present embodiment, the guide rail 232 is a ring-shaped structure, which is advantageous in that when one light adjusting member 400 is moved, the light adjusting member 400 can drive the other light adjusting members 400, so as to realize the movement of all light adjusting members 400, and the ring-shaped guide rail 232 can realize a circular movement process, so that when a user uses the light adjusting member, the user can move the required light adjusting member 400 to the first through hole 211 in both clockwise and counterclockwise directions, thereby simplifying the operation of the user. Further, the guide rail 232 may be provided in a substantially oblong ring structure, or may be provided in a substantially circular ring structure.

When a plurality of light-reducing sheets are selected as the plurality of light-adjusting members 400, in order to further facilitate the user to accurately find the required light-adjusting member 400 in the switching process of different light-adjusting members 400, the plurality of light-reducing sheets are arranged in a manner of sequentially increasing or sequentially decreasing the luminous flux of each light-reducing sheet, i.e., in a manner of sequentially increasing or sequentially decreasing ND4, ND8, ND16, ND32 and ND64, so that when the user switches to a position where a certain light-reducing sheet is located in the first through hole 211, the user can clearly know how many times the required light-reducing sheet needs to be moved and switched according to the current gear of the light-reducing sheet, and the required light-reducing sheet can be moved to the first through hole 211, thereby facilitating the user to quickly perform operation.

Exemplarily, fig. 10 shows an arrangement of a plurality of light adjusting members 400, in which ND4, ND8, ND16, ND32, and ND64 dimming sheets are sequentially arranged to form a substantially ring shape, and a user may move the plurality of light adjusting members 400 clockwise or counterclockwise until a desired light adjusting member 400 is moved to the first through hole 211.
