The electronic device 10 may be any device having a display function, for example, the electronic device 10 may be a mobile phone, a tablet, a computer, a television, and the like, which is not limited in the embodiment of the present application, and the mobile phone is taken as an example to be described below.

Specifically, referring to fig. 1 and 2, the electronic device 10 includes a display device 110 and a first cleaning device 120, wherein the first cleaning device 120 is located inside the display device 110 and connected to the display device 110 for removing dirt such as dust on the display device 110, and compared with manual cleaning, the cleaning burden of the user is reduced. The inner side of the display device 110 may be a side opposite to the display surface of the display device 110.

The first cleaning device 120 may remove dust by vibration, and specifically, the first cleaning device 120 may be used to drive the display device 110 to vibrate to clean the display device 110. Further, the driving frequency of the first cleaning device 120 may be equal to the natural frequency of the display device 110, so that the display device 110 may vibrate at the natural frequency under the driving of the first cleaning device 120, that is, the display device 110 generates a resonance phenomenon, the vibration amplitude is the largest, and the cleaning effect can reach the optimal state.

Alternatively, the display device 110 may include a display main body 113 and a first conductive sheet 114, the first conductive sheet 114 may be attached to the non-display surface of the display main body 113, and the first cleaning device 120 may be located inside the display main body 113 and connected to the first conductive sheet 114. The display main body 113 may be the display device 110 in the related art, which is known in the art and therefore not described herein again; the display device 110 in the embodiment of the present application is formed by adding the first conductive sheet 114 to the display device 110 in the related art, and the arrangement of the first conductive sheet 114 can disperse the vibration acting force transmitted by the first cleaning device 120 to a plurality of positions on the display device 110, thereby realizing effective cleaning of the plurality of positions on the display device 110 and improving the cleaning rate of the display device 110.

The first sub-conductive sheet 1141 is designed to include a first segment 1142 attached to the display main body 113 and a second segment 1143 not attached to the display main body 113 and having flexibility, so that a part of stress generated by the first sub-conductive sheet 1141 in a vibration process can be released through bending deformation of the second segment 1143, thereby preventing the first sub-conductive sheet 1141 from being broken and prolonging the service life of the first sub-conductive sheet 1141.

With reference to fig. 7 and fig. 8, the second display surface 1121 may be disposed on a side opposite to the first display surface 1111 of the first display 111 in the second state, such that the first display surface 1111 forms a display area of the display device 110 in the second state. In the second state, the second display surface 1121 and the first display surface 1111 may be disposed to face each other so that the other display surface on the display device 110 may be a display area of the display device 110 in the second state, and the display area of the other display surface is smaller than the sum of the display areas of the first display surface 1111 and the second display surface 1112.

When the first casing 141 and the second casing 142 slide relatively in a direction away from each other, the second display screen 112 is moved out from the first casing assembly 140, and in a process that the second display screen 112 is moved out, dirt on one side of the second casing 142 away from the first casing 141 is driven to move, so that a part of the dirt is transferred to the second display screen 112 which is unfolded, that is, the dirt on the display device 110 is mainly dispersed at the second display screen 112, for this reason, the first cleaning device 120 may be disposed corresponding to the second display screen 112, so as to specifically clean the second display screen 112.

Moreover, the design of the fourth segment can also weaken the noise generated by the display device 110 during the vibration process, thereby improving the user experience.

Since the display device 110 is switched between the first state and the second state, the first display screen 111 and the second display screen 112 and the first casing 141 and the second casing 142 move relatively to each other, the first positioning element 151 and the second positioning element 152 are respectively disposed on the first display screen 111 and the second display screen 112 or on the first casing 141 and the second casing 142, respectively, so as to detect the switching of the display device 110 between the first state and the second state.

Optionally, the first positioning element 151 includes a hall sensor 1511, the second positioning element 152 includes a magnetic element 1521, and when the display device 110 is switched between the first state and the second state, the relative position between the hall sensor 1511 and the magnetic element 1521 changes, so that the magnetic field strength detected by the hall sensor 1511 changes, and whether the display device 110 is switched between the first state and the second state can be known through the change of the magnetic field strength detected by the hall sensor 1511.

Optionally, when the first casing 141 and the second casing 142 are connected in the above-mentioned relatively slidable manner, in an exemplary scheme, the second positioning element 152 may include more than two magnetic elements 1521, the more than two magnetic elements 1521 may be disposed along the sliding direction of the first casing 141 relative to the second casing 142, one of the magnetic elements 1521 corresponds to the hall sensor 1511 in the first state, and the other of the magnetic elements 1521 corresponds to the hall sensor 1511 in the second state; in another exemplary scheme, the first positioning element 151 includes more than two hall sensors 1511, the more than two hall sensors 1511 may be disposed along a sliding direction of the first casing 141 relative to the second casing 142, one of the hall sensors 1511 corresponds to the magnetic member 1521 in the first state, and the other hall sensor 1511 corresponds to the magnetic member 1521 in the second state. By providing two or more magnetic members 1521 or two or more hall sensors 1511, the amount of relative movement between the first casing 141 and the second casing 142 can be inferred from the detection result of the hall sensors 1511, and the degree of expansion or contraction of the display device 110 can be known.

Alternatively, the magnetic member 1521 may be a magnet or an electromagnet. The electromagnet is only magnetic when being electrified and is not magnetic when not being electrified, so that the electromagnet can be not electrified when the display device 110 does not need to be detected to switch between the first state and the second state, and whether the first cleaning device 120 needs to be started or not can be selectively controlled, and power consumption is reduced.

It should be noted that, besides the above-mentioned manner of using the hall sensor 1511 and the magnetic member 1521 to realize whether the display device 110 is switched between the first state and the second state, the positioning device 150 may also use other manners to detect, which is not limited in this embodiment of the present application.

It should be noted that, the electronic device 10 may be provided with a control key for triggering the display device 110 to switch between the first state and the second state, so that when the control key is clicked, the display device 110 may be switched from the first state to the second state, or may be switched from the second state to the first state, at this time, the electronic device 10 may directly determine whether the display device 110 is switched between the first state and the second state according to a signal received by the control key. Optionally, the control key may be electrically connected to the first processor.

Optionally, the electronic device 10 further includes a detection device, which is configured to detect data, and the detection device is electrically connected to the first processor, and is configured to enable the first processor to receive the detection data of the detection device and determine whether the first cleaning device 120 is activated according to the detection data of the detection device.

The detection device may be used to detect the amount of dirt on the display device 110, and may also be used to detect instruction information of a user, which is not limited in this embodiment of the application. Specifically, when the detection means is used to detect the amount of dirt on the display device 110, the detection means may include a light sensor. The optical sensor may include an optical transceiver sensor, an optical receiving sensor, and the like, which is not limited in this embodiment. For example, the light sensor may include at least one of an infrared sensor, a proximity light sensor. The optical sensors are used for determining the amount of dirt on the display device 110 according to the strength of the received optical signal, for example, for an infrared sensor, the infrared sensor may emit an optical signal to the outside of the display device 110, when the amount of dirt on the display device 110 is small, the intensity of the echo optical signal received by the infrared sensor is weak or the echo optical signal cannot be received, when the amount of dirt on the display device 110 is large, the intensity of the echo optical signal received by the infrared sensor is strong, the amount of dirt on the display device 110 may be determined according to the strength of the echo optical signal received by the infrared sensor, and when the amount of dirt on the display device 110 reaches a threshold value, the first cleaning device 120 is activated to clean.

The infrared sensor and the proximity light sensor may be sensors provided specifically for detecting the amount of dirt on the display device 110, or may be implemented by an existing infrared sensor or proximity light sensor in the electronic device 10. For example, when the user approaches the proximity optical sensor by using the proximity optical sensor that is originally in the electronic device 10, the light signal near the proximity optical sensor can be completely blocked, which is different from the blocking strength of the dirt on the display device 110 with respect to the light signal near the proximity optical sensor, so that the light signal received by the proximity optical sensor when the user approaches is different from the light signal received when the user does not approach, and the approach of the user and the amount of dirt on the display device 110 can be both detected.

When the detection device is used for detecting instruction information of a user, the detection device may include at least one of a gesture sensor and a touch sensor. The gesture sensor and the touch sensor may be specially configured sensors for detecting gestures and touch conditions of the user, or may be based on an original gesture sensor and an original touch sensor in the electronic device 1010.

Optionally, referring to fig. 15, the electronic device 10 may further include a second cleaning device 160, such that both the first cleaning device 120 and the second cleaning device 160 can clean the display device 110 for cleaning. The second cleaning device 160 may remove dust by electrostatic dust removal, laser dust removal, and the like, which is not limited in the embodiment of the present application.

When the second cleaning device 160 removes dust by electrostatic precipitation, the second cleaning device 160 may include a first electrode and a second electrode both electrically connected to a power supply, so that an electric field can be formed between the first electrode and the second electrode, and when the gas containing dust particles passes through the electric field, one of the electrodes may discharge electricity, the gas is ionized, and the negatively charged gas ions in the electric field move toward the other electrode under the action of the electric field force and collide with the dust particles during the movement; the dust particles are charged and move to the other electrode under the action of the electric field force, so that the effect of removing dirt such as dust is achieved.

The outer side of the display device 110 may be a side of the display surface of the display device 110. Specifically, the laser light emitted from the first laser light generating device 161 may be emitted in a direction parallel to the display surface of the display device 110, so that the laser beam is focused near the dirt to be removed, and the ionized air generates a shock wave at the focused point, and the shock wave is rapidly expanded to the periphery, thereby removing the dirt such as dust.

Compared with the contact type cleaning in the related art, which has mechanical acting force on the surface of the display device 110 and causes the abrasion of the display device 110, the laser has a directional effect and can directly act on the dirt on the display device 110 to avoid the contact with the display device 110, so that the nondestructive cleaning can be achieved, and compared with the cleaning liquid in the related art, the laser cleaning is more green and environment-friendly and has lower power consumption.

Optionally, the first laser generating device 161 includes a first laser 1611 and a first light deflecting element 1612, the first laser 1611 is disposed in the first housing assembly 140 and is configured to emit laser light, and the first light deflecting element 1612 is located on a transmission path of the laser light and is configured to deflect the laser light, so that the laser light can reach an outer side of the display device 110, and the display device 110 is cleaned. By providing the first light deflecting element 1612, the transmission path of the laser light can be changed, and compared with directly arranging the first laser 1611 to be located on the side where the display surface of the display device 110 is located, arranging the first light deflecting element 1612 with a smaller size to be at least partially located on the side where the display surface of the display device 110 is located can implement a narrow frame design and the like of the electronic device 10. The first light deflecting element 1612 has a reflecting surface on a transmission path of the laser light, and deflects the laser light. For example, the first light deflecting element 1612 may be a mirror or the like.

It should be noted that at least a portion of the first light deflecting element 1612 may be disposed in the first shell assembly 140 to save space in the electronic device 10, and the first shell assembly 140 may have a light-transmitting property near the first light deflecting element 1612 to facilitate smooth transmission of laser light. Optionally, the outer surface of the first housing component 140 may be provided with a light shielding layer except for the light emitting region of the laser light, so as to ensure the aesthetic appearance of the first housing component 140.

It should be noted that the first light deflecting element 1612 may also change the transmission path of the laser light by refraction. For example, the first light deflecting element 1612 may be a prism, and the specific type of the first light deflecting element 1612 is not limited in the embodiments of the present application.

The boundary line of the display device 110 may be provided with the second cleaning device 160. When the display main body 113 of the display device 110 includes the first display 111 and the second display 112, the second cleaning device 160 may be disposed at a boundary between the first display 111 and the second display 112.
