Description
Technical Field
The present invention relates to a mobile terminal in the field of communications, and more particularly, to a mobile terminal with a wireless mouse function.
Background
With the development of electronics and communication technologies, people have more and more demands on functions of mobile terminals, and the mobile terminals have integrated functions other than conversation, such as surfing the internet, listening to music, playing games and the like.
On the other hand, as the importance of computers in work and entertainment is increasing, a mouse, which is one of the important accessories of computers, is also an important electronic product in work and entertainment. Although the mouse can be replaced by a touch panel and a keyboard, the mouse is still the preferred accessory for computers and other electronic products controlled by a graphical interface in view of experience and convenience. The wireless laser mouse generates an image by reflecting a spot formed by an interference fringe generated by laser light irradiated on a reflecting surface (e.g., a desktop) to a sensor, and performs a contrast analysis on the obtained image by a processor to realize the movement of a computer cursor. At present, due to the advantages of convenience, high resolution, high accuracy and the like, the proportion of the wireless laser mouse in the market is increased.
if the portable mobile terminal has the function of the wireless mouse, the carrying burden of a user can be reduced, the space is saved, and the embarrassment that the operation is difficult because the mouse is not carried when the data on the computer is demonstrated is avoided.
Currently, for example, some mobile phones with wireless mouse function have been researched and developed, but these mobile phones have their limitations, mainly focusing on the following aspects: 1. the mobile phone has a mouse function after being wirelessly connected to a computer through a gyroscope, an acceleration sensor and software matched with the gyroscope and the acceleration sensor on the mobile phone, so that the movement of a cursor of a computer screen is controlled by moving the position of the mobile phone, and the mobile phone is limited by factors such as the sensitivity of hardware and the like, so that the control precision is relatively low; 2. after the mobile phone is connected with a computer through a network, a mobile phone screen is used as a touch pad through software, and the movement of a computer screen cursor is controlled by means of sliding of fingers on the mobile phone screen, so that the mobile phone is relatively poor in experience and inconvenient to operate; 3. adding other specialized devices such as LEDs to the handset would complicate the handset structure and increase cost.
The above information disclosed in this background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not constitute prior art that is already known to a person of ordinary skill in the art.
Disclosure of Invention
An object of the present disclosure is to provide a mobile terminal with a wireless mouse function, thereby overcoming, at least to some extent, one or more problems due to limitations and disadvantages of the related art.
The invention aims to provide a mobile terminal with a wireless mouse function, which comprises: a laser; an optical element switching device for switching an optical element right in front of an emission end of the laser, the optical element switching device including a mounting unit for fixedly mounting the one or more optical elements, a driving unit for moving the mounting unit to complete switching between the optical elements, and one or more optical elements including a first optical element that deflects laser light emitted from the laser, the deflected laser light being obliquely incident on a reflection surface and forming a spot; a sensor for sensing the spot of light reflected by the reflective surface; a processor for analyzing and processing the image generated by the light spot and determining the movement track of the mobile terminal.
The mobile terminal with the wireless mouse function enables laser light from a laser in the mobile terminal to be obliquely incident on a reflecting surface after being deflected through a first optical element, then senses a light spot point generated by the laser light through a sensor, and processes and analyzes an image generated by the light spot through a processor to determine the moving track of the mobile terminal. On one hand, the mobile terminal has the function of a wireless laser mouse; on the other hand, the problems of low accuracy, poor body feeling and the like when the mobile terminal with the mouse function in the prior art is used as a mouse can be solved under the condition that the structure of the mobile terminal is not complicated.

Fig. 1 is a schematic perspective view showing a positional relationship of a laser and an optical element switching device according to an embodiment of the present invention. Fig. 2 is a plan view showing switching of the optical element. In an exemplary embodiment of the present invention, the laser 1 in the mobile terminal may be a laser with adjustable laser intensity, and the control of the laser intensity may be achieved by changing the current flowing through the laser 1, so that the laser 1 is suitable for different applications.
Referring to fig. 1 and 2, a physical means for switching an optical element, i.e., an optical element switching device 2, may be arranged in front of the emission end of the laser 1. In an exemplary embodiment of the present invention, the optical element switching apparatus 2 may include a mounting unit 21, a driving unit (not shown), a first optical element 22, and a second optical element 23.
The mounting unit 21 is used to fixedly mount the first optical element 22 and the second optical element 23 thereon, for example, the mounting unit 21 may include slot holes corresponding to the first optical element 22 and the second optical element 23, respectively, and the first optical element 22 and the second optical element 23 are disposed in the slot holes, respectively, to achieve a fixing function.

< mouse function off when memory Metal sheet is not energized >
In the case where the memory metal sheet is not energized, the second optical element 23 is located right in front of the emitting end of the laser 1, and the laser light emitted from the laser 1 is emitted in a direction perpendicular to a Printed Circuit Board (PCB) of the mobile terminal through the second optical element 23.
According to some embodiments, the second optical element 23 may be a special optical element with different functions for different applications of the laser 1, for example, the second optical element 23 may be a laser beam expander for changing a point light source into a surface light source to supplement light for night view infrared imaging or thermal imaging.
According to some embodiments, the second optical element 23 may comprise a high-transparency material, such as glass or resin.

When the memory metal sheet is energized, the memory metal sheet in the drive unit is deformed, and in this case, as shown in fig. 2, the mount unit 21 connected to the memory metal sheet is rotated counterclockwise so that the first optical element 22 is moved to a position aligned with the emission end of the laser 1, that is, at this time, the laser light emitted from the laser 1 is emitted through the first optical element 22. At the same time, the second optical element 23 is moved to the position illustrated as a dashed circle. At this time, the current flowing through the memory metal sheet may be maintained to maintain the degree of deformation of the memory metal sheet. Further, the mounting unit 21 may be rotated clockwise according to the positional relationship of the different optical elements, which is not particularly limited in the present exemplary embodiment.

However, the present invention is not limited to this, and the mounting unit 21 may be moved by another operation mode of the motor, which is not particularly limited in the present exemplary embodiment.
In an exemplary embodiment of the present invention, the driving unit may be controlled by means of software.
Further, the present invention is not limited thereto, and the switching between the optical elements may be realized by other means.
Fig. 3 is a schematic diagram of the implementation of the laser mouse function.
Referring to fig. 3, the laser light may be deflected in angle by the first optical element 22, and then a spot formed by interference fringes generated when the laser light is incident on a reflective surface (e.g., a table) under the mobile terminal is reflected to the sensor 3 through the reflective surface. The sensor 3 senses the light spots and sends the sensed light spots to a processor (not shown), and the processor performs a comparative analysis process on an image generated by the light spots to determine a moving track of the mobile terminal, so as to control the movement of a cursor on a computer screen.
