[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 This is an exploded view of a mobile phone according to an embodiment of the present invention with the display screen assembly hidden. The mobile phone includes: a housing 10 and a laser keyboard device and a communication device disposed within the housing 10.

[0033] Please see Figure 2 This is a schematic diagram of the bottom structure of a mobile phone according to an embodiment of the present invention. The housing 10 is provided with a first support surface 12 located at its bottom and a plurality of light-transmitting parts 11 located at its front side. The first support surface 12 is a plane.

[0034] Please see Figure 3 and Figure 4 They are respectively Figure 1 The enlarged view at point A shown and Figure 1 The enlarged view at point B shows that the laser keyboard device includes a projection component 21, a camera component 22, an infrared emitting component 23, and an image analysis module (not shown). The projection component 21, camera component 22, and infrared emitting component 23 are exposed from the light-transmitting part 11 in a one-to-one correspondence. The projection component 21 and camera component 22 are positioned near the top of the housing 10, with the projection component 21 tilted towards the bottom of the housing 10, forming an acute angle with the first support surface 12. The infrared emitting component 23 is positioned near the bottom of the housing 10, with its emission direction parallel to the first support surface 12. The image analysis module is connected to the camera component 22. Because mobile phones are relatively thin, the projection component 21 and camera component 22 need to be spaced a certain distance from the infrared emitting component 23, and can only be positioned on the back or front of the phone. However, placing the phone vertically usually causes it to fall over. The first support surface 12 improves the stability of the phone, facilitating stable vertical placement.

[0035] The projection component 21 is used to project a keyboard-shaped pattern onto a target plane parallel to the first support surface 12. The keyboard-shaped pattern is located in front of the infrared emitting component 23. When the user's finger clicks on the keyboard-shaped pattern, the finger will reflect the infrared light signal emitted by the infrared emitting component. It should be noted that the user may also use other substitute objects to click instead of their finger. The substitute object should also be understood as the user's finger.

[0036] The camera component 22 is used to acquire an image of the target plane. Since the light signal reflected by the finger can be collected when acquiring the image of the target plane, the position of the light signal in the image is analyzed relative to the position of the keyboard-shaped pattern by the image analysis module, thereby determining the position of the finger on the keyboard-shaped pattern, and then determining the key that the user clicked on the keyboard-shaped pattern, so as to realize key input through the laser keyboard device.

[0037] In some optional embodiments, the front side of the housing 10 is further provided with a receiving groove 13 and a display cover 14, the display cover 14 covering the opening of the receiving groove 13, the projection component 21 and the camera component 22 are disposed at the top of the receiving groove 13, the infrared emitting component 23 is disposed at the bottom of the receiving groove 13, and the light-transmitting part 11 is disposed on the display cover 14; the mobile phone also includes a display component (not shown) and a processing module (not shown), the display component is disposed in the receiving groove 13, located in the middle of the receiving groove 13, between the camera component 22 and the infrared emitting component 23, the camera component 22 and the projection component 21 are located above the display component, the infrared emitting component 23 is located below the display component, and the processing module is connected to the display component and the image analysis module respectively. Because the phone is placed vertically, the image analysis module converts the key press information from the user's touch into electrical signals and sends them to the processing module. The processing module then transmits the display signals to the display screen assembly. The display screen is positioned on the front of the phone, which is beneficial for users to see their input information displayed on the screen when using a laser keyboard, thus improving the user experience. The processing module can be a CPU or other module with processing capabilities. The display screen cover 14 also has a transparent section for exposing the display screen assembly; the display screen cover 14 can be made of glass, but is not limited to this example. A communication device can be connected to the processing module.

[0038] In some optional embodiments, the infrared emitting component 23 is an infrared linear laser that emits light signals parallel to the first support surface 12, so that the light signals can uniformly cover the top of the keyboard-shaped pattern.

[0039] In some optional embodiments, the mobile phone further includes a processing module disposed within the housing 10. This processing module is connected to the image analysis module, the camera assembly 22, the infrared emitting assembly 23, and the projection assembly 21, respectively. The camera assembly 22 continuously acquires images of the target plane. The image analysis module is also used to analyze whether a human hand exists in the image. The specific principle of analyzing whether a human hand exists in the image is well-known to those skilled in the art and will not be elaborated here. When the time in which no human hand exists in the image exceeds a preset time, the processing module sends a control signal to the camera assembly 22, the infrared emitting assembly 23, and the projection assembly 21, turning off the camera assembly 22, the infrared emitting assembly 23, and the projection assembly 21, thereby preventing the camera assembly 22, the infrared emitting assembly 23, and the laser keyboard device from continuously operating in an idle state.

[0040] In this embodiment, a power supply device is also provided inside the housing, which is connected to the image analysis module, the camera component 22, the infrared emitting component 23, the projection component 21, the processing module, and the communication device.

[0041] Please see Figure 5 and Figure 6 These are, respectively, a schematic diagram of the front side of a phone case according to an embodiment of the present invention and a cross-sectional view of a part of the structure of a phone and a phone case according to an embodiment of the present invention. To protect the phone, a phone case 30 is typically used to cover it, thereby improving phone security. To avoid difficulty in maintaining the phone stably when the phone case 30 is on, in some optional embodiments, the phone also includes a phone case 30. The phone case 30 has a storage groove 31 on its front side and a second support surface 32 on its bottom side. The housing 10 is disposed within the storage groove 31, and the second support surface 32 is parallel to the first support surface 12. The second support surface 32 can stably support the phone case 30 and the phone.

[0042] To further improve the stability of the phone case 30 when it is upright, in some optional embodiments, a support block 33 is provided at the bottom of the phone case 30, and the support block 33 is rotatably connected to the phone case 30; a third support surface 331 is provided on the support block 33, and the third support surface 331 is parallel to the second support surface 32. When the support block 33 is in the idle position, the third support surface 331 is located at the top of the support block 33 and abuts against the first support surface 12. At this time, the support block 33 and the phone case 30 have an integrated structure, which improves the aesthetics. After the support block 33 is flipped to the rear side of the phone case 30, the support block 33 moves from the idle position to the use position. At this time, the support block 33 is located on the rear side of the phone case 30, and the side of the support block 33 abuts against the rear side of the phone case 30. The third support surface 331 is located at the bottom of the support block 33. The third support surface 331 and the second support surface 32 are located on the same plane. The second support surface 32 and the third support surface 331 jointly support the phone case 30 and the phone. Due to the increased support area, the stability is improved.

[0043] Please see Figure 7 This is a schematic diagram of the rear structure of a mobile phone case according to an embodiment of the present invention.
