All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, the present embodiment provides a sliding door assembly 10, which mainly includes a door frame 11 and a sliding door 12, wherein the door frame 11 may be disposed in a functional area that may need to be isolated from the outside in some cases, for example, in the present embodiment, the sliding door assembly 10 may be disposed in a shower area of a bathroom, so as to be separated from the bathroom when needed, and of course, may also be a living balcony or a public place, and the like, which is not limited herein. The sliding door 12 may be mounted to the doorframe 11 while the sliding door 12 may be selectively powered on or off and assume a transparent state when the sliding door 12 is powered on and a fogging opaque state when the sliding door 12 is powered off.

Referring to fig. 2, the door frame 11 mainly includes a side plate 112 and a base plate 111, wherein the side plate 112 may be enclosed in the base plate 111, specifically, the side plate 112 may include a first side plate 1121 and a second side plate 1122, the first side plate 1121 and the second side plate 1122 may be oppositely disposed and respectively connected to two sides of the base plate 111, so that the side plate 112 and the base plate 111 enclose a sliding slot 114, and the sliding slot 114 may be used for assembling the sliding door 12, so that the sliding door 12 may reciprocate along the sliding slot 114. Referring to fig. 2 and 3, in the extending direction of the sliding slot 114, the sliding slot 114 may include a first region 1141 and a second region 1142 adjacent to each other, and the lengths of the first region 1141 and the second region 1142 along the extending direction of the sliding slot 114 may be equal.

Referring to fig. 3 and 4, in the present embodiment, the first region 1141 is provided with a conductor 13 for connecting the power source 20, and the second region 1142 is provided with an insulator 14. Referring to fig. 1 and 4, when the sliding door 12 slides to the first region 1141, the sliding door 12 contacts the conductor 13, so that the sliding door 12 is transparent after being powered on; when the sliding door 12 slides to the second region 1142, the sliding door 12 contacts the insulator 14, such that the sliding door 12 assumes a fog-opaque state after power is turned off. It is understood that when the sliding door 12 is in contact with the conductor 13 and the insulator 14, respectively, the sliding door 12 inevitably applies force to the conductor 13 and the insulator 14, in order to reinforce the strength of the conductor 13 and the insulator 14, the conductor 13 and the insulator 14 may be disposed on the substrate 111, and when the sliding door 12 is in contact with the conductor 13 or the insulator 14, the substrate 111 applies reaction force to the conductor 13 and the insulator 14, so that the conductor 13 and the insulator 14 are balanced in force, and the conductor 13 and the insulator 14 are prevented from being subjected to unbalanced force for a long time, and the service life of the conductor 13 and the insulator 14 is shortened.

It should be noted that the conductor 13 may be a conductive copper sheet, and the insulator 14 may be PVC (Polyvinyl Chloride) plastic, and of course, the conductor 13 and the insulator 14 may also be made of other materials, which is not limited herein.

When one of the first conductor 131 and the second conductor 132 is damaged, the other may also contact the sliding door 12, thereby extending the service life of the sliding door assembly 10.

In other embodiments, the conductor 13 may further include a third conductor, and both are spaced apart side-by-side from the first conductor 131 and the second conductor 132.

In addition, the sliding plate 113 can prevent liquid water from splashing into the conductive area of the conductor 13 and the sliding door 12, thereby ensuring the safety of electricity.

In other embodiments, a sliding member with a smaller surface roughness may be used instead of the pulley 122, and at the same time, the surface roughness of the first sliding plate 1132 and the second sliding plate 1133 is also reduced, so that the sliding friction between the sliding member and the first sliding plate 1132 and the second sliding plate 1133 is smaller, which may also meet the user's requirement.

In other embodiments, the conductive wire 124 may not be inserted through the wire hole 1224, but may be routed outside the pulley holder 1223, so that the brush 123 is electrically connected to the plate body 121.

Referring to fig. 7 and 8, in order to make the plate body 121 in a transparent state when the panel body 121 is powered on and in an opaque state when the panel body 121 is powered off, in the embodiment, the plate body 121 may be provided with a liquid crystal film 1211, and when the liquid crystal film 1211 is powered on, the liquid crystal film 1211 is in a transparent state; when the liquid crystal film 1211 is turned off, the liquid crystal film 1211 assumes a fog-opaque state.

According to the sliding door assembly 10 and the shower door 100 provided by the embodiment of the application, the conductor 13 and the insulator 14 are respectively arranged in the first area 1141 and the second area 1142 adjacent to each other in the sliding slot 114 of the door frame 11, when the pulley 122 assembled in the sliding slot 114 is located in the first area 1141, the sliding door 12 is located at a corresponding position of the first area 1141, and the brush 123 is electrically contacted and conducted with the conductor 13, so that power is supplied to the liquid crystal film 1211 electrically connected with the brush 123 through the wire 124, and the liquid crystal film 1211 is in a transparent state under the condition of being electrified; when the pulley 122 is located in the second region 1142, the brush 123 contacts the insulator 14, thereby deenergizing the liquid crystal film 1211, so that the liquid crystal film 1211 images an opaque state of fog. The sliding door assembly 10 selectively slides to the first region 1141 or the second region 1142 through the sliding door 12, so as to automatically change whether the sliding door 12 is in a transparent state or an opaque state, which is convenient and trouble-saving, and does not need to provide an additional control switch or sensor, etc., thereby reducing the product cost.
