Problems solved by technology

[0003]In the existing technology, the decisive factors affecting the service life and mass production of the scroll screen are not only the life of the motor and the flexible screen itself, but the scroll screen will encounter problems in actual use scenarios. Foreign matter, such as hair strands, scraps of waste paper, and foreign matter will enter the interior of the mobile phone along with the movement track of the OLED flexible screen, causing the constant force motor to stop the reel due to torque overload, and even cause the constant force motor to fail, thereby greatly reducing the constant force service life of the motor

Embodiment 1

[0037] like figure 1 , figure 2 , image 3 As shown, this embodiment proposes a foreign matter detection and removal device, which can identify foreign matter entering the terminal housing, prevent and remove foreign matter, thereby greatly improving the use stability and service life of the terminal device.

[0038] Specifically, the above-mentioned foreign matter detection and removal device is mainly applied to a terminal device with a scroll screen 4, and the terminal device may be a mobile phone, a tablet computer, and the like. Part of the scrolling screen 4 of the terminal device is located inside the terminal housing, and forms an accommodating space with the terminal housing, and the foreign matter detection and removal device is installed in the accommodating space. The terminal casing is generally divided into two parts, one is the first casing 1, and the other is the second casing 10. When the scroll screen 4 is retracted or unfolded, the first casing 1 faces or...

Embodiment 2

[0052] like Figure 4 As shown, Embodiment 2 is roughly the same as Embodiment 1, and the similarities will not be repeated. The main difference is that a further improvement is made on the basis of Embodiment 1. The improvement is that the foreign matter detection and removal device also includes a stopper part 8, the stop part 8 is installed on the bottom surface of the terminal housing, that is, the bottom surface of the first housing 1, the stop part 8 is located at the lower end of the foreign object removal assembly 9, and the stop part 8 and The first housing 1 forms a receiving cavity, and the receiving cavity is used to store foreign objects entering the terminal housing. Preferably, the stop member 8 is a baffle, and the baffle can be made of rubber material. The rubber baffle can further prevent unremoved foreign matter from entering the interior of the terminal housing, and has a double protection effect on the terminal equipment.

Embodiment 3

[0054] like Figure 5 As shown, this embodiment is substantially the same as Embodiment 2, and the similarities will not be repeated. The main improvement is that the terminal housing includes a first housing 1 and a second housing 10, and the first housing When the scroll screen 4 retracts or unfolds, the body 1 faces or moves away from the second casing 10; the first casing 1 is provided with a side cover 2, and the side cover 2 is connected with the first casing. body 1 is detachably connected, and when the side cover 2 is opened, the accommodating space is exposed, and an accommodating cavity is provided in the accommodating space, and the accommodating cavity is used to store foreign objects entering the terminal housing. A detachable side cover 2 is provided on the casing 1, on the one hand, it is convenient for the user to open the side cover 2 to regularly clean the remaining foreign matter, and on the other hand, it is also convenient for the maintenance of the foreig...

Abstract

The invention provides a foreign matter detection and removal device. The foreign matter detection and removal device is installed in a containing space formed by a terminal shell and a scroll screen. The foreign matter detection and removal device comprises a driving part, a pulling mechanism, a foreign matter sensing part and a foreign matter removing assembly. The foreign matter sensing part is installed in the terminal shell and used for detecting foreign matter on the scroll screen in the process that the scroll screen retracts into the shell, and when the foreign matter sensing part detects the foreign matter, the scroll screen stops retracting, and the pulling mechanism drives the foreign matter removing assembly to make contact with the scroll screen; and when the scroll screen is unfolded in the reverse direction, the driving part drives the foreign matter removing assembly to rotate and pushes the foreign matter towards the outside of the terminal shell. According to the device, the foreign matter on the scroll screen can be automatically detected through the foreign matter sensing part, and the foreign matter removing assembly can prevent the foreign matter from entering the terminal shell, so that the foreign matter is removed.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular, to a foreign object detection and removal device and method. Background technique [0002] In the scrolling screen concept mobile phone, the design of the scrolling screen is to embed two constant force motors inside the fuselage. When the user triggers the switch, the motor can unfold or retract the model according to the "constant force". At the same time, the UI will also change at any time according to the size of the fuselage. The design solves the technical problems of internal or external folding. The flexible OLED screen is 7.8-8.6 inches when unfolded, and 6.2-6.7 inches when closed, and the 6.5-6.8mm pulley reel inside the model protects the screen well, so there are almost no creases. [0003] In the existing technology, besides the motor and the life of the flexible screen itself, the decisive factors affecting the service life and mass production of t...
