Detailed ways

In order to make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The technical solutions disclosed in the various embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 5, an embodiment of the present application discloses an electronic device, including:

A screen unit 1 and a camera module 2. The screen unit 1 includes a screen body and a through slot provided on the screen body, and a contraction portion 101 connected to the screen body on one side is provided in the through slot. The camera module 2 is located inside the electronic device and is arranged opposite to the constriction 101.

The constriction 101 includes a memory metal layer 1011 and a sub-screen layer 1012 disposed on a first surface of the memory metal layer 1011, as shown in FIG. 2. The first surface may be the upper surface of the memory metal layer 1011. When the camera module 2 is in the first state, the memory metal layer 1011 drives the contraction part 101 to expand. The state may be a state in which the camera module does not use the camera function, and the screen unit 1 may present a full-screen display effect; when the camera module 2 is in the second state, the memory metal layer 1011 drives all The constriction 101 shrinks and leaves a light-transmitting hole opposite to the camera module 2. The second state may be the imaging state of the camera module, and then the light-transmitting hole can facilitate the The camera module 2 performs shooting.

Specifically, the contraction part 101 is connected to one side of the screen body. On the one hand, it can ensure that the contraction part 101 is not affected when switching between the expanded state and the contracted state, and on the other hand, it can be provided by the screen body. The electrical signal is given to the contraction part 101 to facilitate the normal display of the contraction part 101 in the unfolded state.

In order to increase the screen ratio of the traditional full-screen electronic equipment, the camera is mainly pushed out when the camera is in use by using a lifting motor inside the whole machine, or by punching holes under the screen to display the use of a digging screen. However, this setting will greatly affect the internal stacking of the electronic equipment, resulting in an increase in the thickness of the whole machine; or the part of the screen where the camera is located will not function as a display, and the aesthetics of the appearance will be greatly reduced. In the electronic device of the present application, by providing the contraction part 101 on the screen unit 1, the contraction part 101 can be expanded and contracted, and cooperates with the camera function of the camera module 2, which not only achieves the aforementioned The full display effect of the full screen of the screen unit 1 increases the screen-to-body ratio and also completes the camera function well.

At this time, the screen unit 1 is a complete full screen, and then a true full screen display can be completed.

The hot-deformed alloy can completely eliminate its deformation at a lower temperature after heating and increasing, and restore the original state before the deformation. Specifically, the memory metal layer 1011 may be in a contracted state when the temperature is high, and in an expanded and deformed state at normal temperature. If the memory metal layer 1011 in the expanded state is heated, such as resistance heating or energization to generate heat, it can drive the contraction portion 101 to recover from the expanded state to the contracted state. After the heat source is removed, the memory metal layer 1011 can drive it again The contraction part 101 is switched from the contracted state to the expanded state, so that it can be well matched with the shooting state of the camera module 2 to complete the dual functions of full-screen display and flexible shooting.

The high-temperature phase of the memory metal mesh has high structural symmetry, and is usually an ordered cubic structure. Below the Martensite start temperature (Martensite Start, Ms), a single-oriented high-temperature phase transforms into a martensite variant with different orientations. When the material is deformed to make a component below the Ms temperature, the martensite variants in the material that are in a disadvantageous position with the direction of stress continue to diminish, while those in a favorable position continue to grow, and finally transform into an orderly one with a single orientation. Elements of martensite. When the memory metal mesh is heated above the martensite reversal temperature As, this low-symmetric, single-oriented martensite undergoes reverse transformation, and the previous single-oriented high-temperature phase is formed. Corresponding to this reversible transformation of the microstructure, the macroscopic shape of the material at high temperature is restored, which is the so-called one-way shape memory. When the processed memory metal mesh is cooled below Ms, it can return to the shape at low temperature, which is called the two-way shape memory effect. The memory metal layer 1011 of the present application has a two-way shape memory effect, which can provide a deformed shape and force to drive the deformation of the contraction portion 101, and the resin coating layer can play a role in protecting the memory metal mesh, and The resin coating layer has a certain viscosity during molding, which can facilitate the adhesion and fixation of the memory metal layer 1011.
