[0002] As infrared products gradually penetrate into consumer electronics, home appliance testing, outdoor and other fields, consumers have put forward new requirements for product diversity, aesthetics, miniaturization, ease of use, and protection. In response to this, some people have proposed a pocket infrared device, such as a pocket infrared thermal imager. As a pocket device, small / light / easy to use is crucial. In order to make the product smaller and have good protection, the most direct way at present is the folding / flip solution. The folding / flip design involves the electrical connectivity of the front and rear modules. The more conventional solution is a design similar to a flip phone. The front and rear modules are connected by rotating shafts, and holes are set in the inner cavity of the shaft for the wiring harness (for example, the wire diameter is 4mm) and FPC (flexible circuit board) to pass through to achieve electrical connection between the front and rear modules, and a protective design is performed between the shaft and the module housing.

DETAILED DESCRIPTION

[0022] Before describing the embodiments in detail, it should be understood that the present application is not limited to the detailed structure or component arrangement described below or in the drawings in the present application. The present application may be an embodiment implemented in other ways. Moreover, it should be understood that the words and terms used herein are only used for descriptive purposes and should not be interpreted restrictively. The words "including", "comprising", "having" and the like used herein are meant to include the items listed thereafter, their equivalents and other additional items. In particular, when describing "a certain element", the present application does not limit the number of the element to one, but may also include multiple elements.

[0023] Please also refer to Figures 1 to 3 As shown, the present application provides an infrared device 10, which can be a pocket infrared thermal imager, a pocket infrared detector, or other infrared devices. In the present application, the infrared device 10 includes a first part 100, a second part 200, and a connection structure 300. The first part 100 is rotatably connected to the second part 200, so that the infrared device 10 has a folding / flipping function, wherein the connection structure 300 includes a flexible member 301 and a conductive member 302 penetrating the flexible member 301. One end of the flexible member 301 is connected to the first part 100 and the other end is connected to the second part 200. The first part 100 and the second part 200 are electrically connected through the conductive member 302, and the flexible member 301 and the conductive member 302 can be deformed with the rotation of the first part 100 or the second part 200.

[0024] As a folding / flip device, it is extremely important to ensure the reliability of the existing pocket infrared device. Since the wiring harness / FPC passes through the inner cavity of the shaft, and the shaft is mostly made of metal, the shaft will cause wear to the wiring harness / FPC during folding / flipping, thereby reducing the reliability of the device. The present application can effectively solve the problem of limited space in the inner cavity of the existing shaft by additionally setting a connection structure 300 between the first part 100 and the second part 200. The flexible part 301 can adapt to the design of more and wider conductive parts 302, so that the infrared device 10 can develop rapidly in the direction of miniaturization, lightness, and diversification. In addition, the connection structure 300 is easy to install and has clear wiring, eliminating the need for processing and design of the shaft, reducing costs, and using the flexible part 301 to cover the conductive part 302 can effectively avoid wear of the conductive part 302 and improve reliability.

[0025] Among them, the flexible part 301 can be made of a material with elasticity, waterproofness and other properties, such as rubber or silicone, and can be designed as a simple rubber plug or silicone plug. Whether in terms of material or design itself, the cost is significantly reduced. The flexibility, compressibility and other characteristics of the elastic material can avoid the problem of wear of the conductive part 302 when the device is folded / flipped, causing device abnormalities, thereby increasing reliability; the conductive part 302 can be a columnar wire, wiring harness or FPC with deformation ability to achieve electrical connectivity between the first part 100 and the second part 200.

[0026] The first part 100 is rotatably connected to the second part 200. Specifically, the first part 100 can be rotated relative to the second part 200 between a folded position and an open position, wherein when the first part 100 is in the folded position, the first part 100 is superimposed on the second part 200; when the first part 100 is in the open position, the first part 100 is rotated away from the second part 200 and forms an angle with the second part 200.

In this embodiment, one connection structure 300 is provided, and the flexible member 301 has a certain width in the axial direction of the rotating shaft 502, and the design requirements for the internal space of the rotating shaft are abandoned, so the volume of the rotating structure 500 can be reduced as much as possible, so that the product can adapt to the design requirements of thinner thickness, more wiring harnesses, and wider FPC, and enhance adaptability and compatibility. In other embodiments, multiple connection structures 300 can also be provided, and multiple connection structures 300 are arranged along the axial direction of the rotating shaft 502.

The first convex edge 307 protrudes out of the side wall of the flexible member 301 along the circumferential direction. The first connection portion 306 is fixedly connected to the first through hole 103. For example, the first connection portion 306 is inserted into the first through hole 103 by extrusion until the first convex edge 307 is in contact with, for example, completely in contact with, the bottom wall of the first receiving groove 101.
