Referring to fig. 1 and 2, fig. 1 is a partial schematic view of a window assembly of a monitoring device according to the present application; FIG. 2 is another schematic view of a portion of a window assembly of the monitoring device of the present application.

In this embodiment, the monitoring device (not shown) may be a camera, wherein the camera may be a ball machine or a gun machine, and is not limited herein. The monitoring device comprises a device body (not shown in the figure) and a window assembly 1, wherein the window assembly 1 is arranged on the device body, and the device body can acquire an optical image through the window assembly 1. Wherein window subassembly 1 includes window component 11 and conducting layer 12, and window component 11 sets up on the equipment body, can obtain the image through window component 11. The shape of the window element 11 may be circular or square, etc., wherein the shape of the window element 11 may be determined according to the application of the window element to the internal structure of the device body, and is not limited herein.

In general, the conductive layer 12 is disposed in a peripheral region of a side of the window element 11 facing the apparatus body, wherein the conductive layer 12 has a conductive property. The shape of the conductive layer 12 may be determined according to the shape of the window element 11, and when the window element 11 is circular, the conductive layer 12 may be annularly distributed on an outer peripheral area of one side of the window element 11; when the window element 11 has a square shape, the conductive layer 12 may be distributed in a square shape on a side peripheral area of the window element 11. The conductive layer 12 is a non-closed structure, wherein the conductive layer 12 includes a first end 121 and a second end 122 opposite to each other, a notch 123 is formed at the first end 121 and the second end 122, and the notch 123 prevents conduction between the first end 121 and the second end 122 during the process of heating the conductive layer 12 by applying electricity. The gap between the notches 123 may be determined according to actual conditions, and is not limited herein.

The window assembly 1 further comprises a wiring member 13, one end of the wiring member 13 being connected to the first end 121 and the second end 122 of the conductive layer 12, respectively, and the other end being adapted to be connected to a power source. That is, the circuit member 13 connects the power supply (not shown in the figure) and the conductive layer 12, so that the conductive layer 12 is electrified and self-heated, thereby heating the window element 11, further enabling the window element 11 to have the effects of fog prevention, frost prevention, icing prevention and the like, and further meeting the requirements of the monitoring device in low-temperature environment, high-humidity area or scene with large temperature difference change.

Compare in prior art, window subassembly 1 simple structure in this embodiment only needs 11 internal surface peripheries of window component to set up conducting layer 12, and then conducting layer 12 passes through circuit spare 13 and can solve and appear on the supervisory equipment fog, have the frost and have the scheduling problem that freezes, has also reduced the cost simultaneously.

Above-mentioned conducting layer 12 can be silk-screened on window component 11 towards the side periphery of equipment body for conducting layer 12 thickness is more even and level and smooth, thereby makes conducting layer 12 evenly generate heat. Of course, the conductive layer 12 may be applied to the periphery of the side of the window element 11 facing the device body, which is not limited herein. The circuit member 13 is two lead wires, one of which is connected to the first end 121 of the conductive layer 12, and the other of which is connected to the second end 122 of the conductive layer 12, wherein the two lead wires are connected to a power supply. Wherein the lead wire can be a conventional wire such as a conducting wire, an electric wire and the like.

In one embodiment, with reference to fig. 1 and 2, the window assembly 1 includes a fixing member (not shown) disposed on the first end 121 and the second end 122 of the conductive layer 12, wherein the circuit element 13 is fixed on the first end 121 and the second end 122 by the fixing member, respectively. In this way, stable connection and conductive connection between the circuit member 13 and the conductive layer 12 can be improved.

The fixing member may have any structure as long as the circuit member 13 can be connected to the first end 121 and the second end 122 of the conductive layer 12 and can be conducted, and is not limited herein. If the conductive layer 12 is a conductive ink layer, a conductive carbon paste layer, or a combination of the conductive ink layer and the conductive carbon paste layer, the fixing element can be the conductive portion 14, and the conductive portion 14 is located at the first end 121 and the second end 122, so that the conductive portion 14 can be connected to the first end 121 and the second end 122, and the circuit element 13 can be stably soldered on the conductive portion 14, thereby achieving the conductive connection between the circuit element 13 and the conductive layer 12 through the conductive portion 14. In addition, when the conductive layer 12 is a conductive ink layer or a conductive carbon paste layer, since the conductive layer itself has a darker color, it is not necessary to add a corresponding insulating layer to cover the color, etc., thereby reducing the production cost.

The conductive portion 14 may be a conductive silver paste portion or a conductive copper paste portion, wherein the conductive silver paste portion and the conductive copper paste portion have conductivity. The first end 121 and the second end 122 may be both provided with a conductive silver paste portion, or both provided with a conductive copper paste portion; or the first end 121 is provided with a conductive silver paste portion, the second end 122 is provided with a conductive copper paste portion, and the like. The conductive silver paste portion or the conductive copper paste portion is specifically located at the first end 121 or the second end 122 according to actual situations. Therefore, the conductive silver paste portion or the conductive copper paste portion can not only be conducted with the first end 121 or the second end 122, but also play a role in fixing the circuit member 13.

Alternatively, the conductive portions 14 may be partially screen-printed on the first end 121 and the second end 122, and then the conductive portions 14 are connected to the circuit member 13. Wherein the conductive portions 14 may be partially screen printed on the sides of the first end 121 and the second end 122 away from the window element 11. Or the conductive part 14 may be partially screen-printed on the periphery of a side of the window element 11 facing the device body, and then the first end 121 and the second end 122 of the conductive layer 12 are screen-printed on the conductive part 14. Of course, in other embodiments, the conductive portion 14 may be located at other positions of the first end 121 and the second end 122, and all such positions are within the scope of the present invention. The conductive portion 14 is located on a side of the first end 121 and the second end 122 away from the window element 11 in this embodiment.

Alternatively, the thickness of the conductive layer 12 may be 0.1mm, 0.2mm, 0.3mm, or the like.

In practice, the resistance of the conductive layer 12 affects the heat generation efficiency of the conductive layer 12. For example, the resistance of the conductive layer 12 may be related to the extension length of the conductive layer 12, the cross-sectional width of the conductive layer 12, the resistivity of the conductive layer 12, and the like, so that the resistance of the conductive layer 12 may be changed by changing the above factors, thereby controlling the heating condition of the conductive layer 12, and further controlling the defrosting, defogging, deicing, and other effects of the window element 11.
