A display screen cover layer such as a transparent glass layer, light-transmissive plastic, sapphire, or other transparent dielectric layer may be used to protect the display screen 100. In some embodiments, the display screen 100 may be a flexible screen, i.e., the display screen 100 may be bendable and foldable.

The housing 200 may include a middle frame, such as middle frame 220, and a back cover, such as back cover 240. The middle frame 220 may serve as a carrier for the electronic device 20. For example, the bezel 220 may carry the display screen 100, the circuit board 800, a battery, etc. of the electronic device 20. The middle frame 220 may be made of metal, and may be formed by injection molding or machining.

The rear cover 240 may be disposed on one side of the middle frame 220, such as the rear cover 240 disposed on a non-display side of the middle frame 220. The rear cover 240 and the middle frame 220 are fixedly connected to form a receiving cavity 220 for receiving devices of the electronic apparatus 20, such as a battery, a circuit board 800, and the like, so that the rear cover 240 can be covered on the middle frame 220 to cover the battery, the circuit board 800, and the like. It is understood that the display screen 100 and the rear cover 240 are disposed at two opposite sides of the middle frame 220, and the display screen 100 may be disposed at a display surface of the middle frame 220 to display a picture.

The middle frame 220 may have a plurality of sides 222, and the plurality of sides 222 of the middle frame 222 are all located on the periphery of the base of the middle frame 220. The lengths of the sides 222 of the middle frame 220 may be the same or different. Such as the middle frame 220, may have a first side with a longer length and a second side with a shorter length, i.e., the first side may have a length greater than the second side. Devices of the electronic apparatus 20 such as the operation switch 400 may be disposed on one or more of the sides 222 of the middle frame 220, such as the operation switch 400 of the electronic apparatus 20 disposed on one of the longer sides 222 of the middle frame 220.

The operation switch 400 may be provided on the side 222 having a shorter length. It is understood that when the lengths of the sides 222 are the same, the operation switch 400 may be disposed on any one side 222 or any plurality of sides 222. It will also be appreciated that the operating switch 400 may be disposed at the connecting position of the two connecting sides 222, or at the corner position of the middle frame 220. It will also be appreciated that one of the sides 222 may be provided with one or more operating switches 400. In some embodiments, a control area 2222, or an operation area 2222, may be provided on one of the side edges 222. The operation switch 400 may be provided in the control section 2222 of the side 222 for the user to operate. Of course, it is also possible to arrange the operation switches 400 at all positions of the side 222, i.e., the control section 2222 is the entire side 222.

In some embodiments, a self-luminous material may be disposed at the control area 2222 to allow the user to recognize the controller 2222. The color settings at the location of the control area 2222 may be different from the color settings at other locations of the side edge 222. A light emitting lamp may also be provided in the control section 2222.

In the related art, a plurality of physical keys, such as an on-off key, a volume key, a shortcut key, etc., are disposed on a side of the electronic device. The physical keys generally protrude out of the side edges, and gaps are formed between the physical keys and the side edges of the electronic equipment, so that water leakage and dust entering are easy to occur.

Based on this, in the embodiment of the present application, the operation switch 400 is disposed on the inner surface of the side edge 222, and the user can directly operate the control area 2222 to control the operation switch 400. The integrity of the side 222 is maintained and is waterproof and dustproof.

The side 222 may be provided with a first receiving groove 2224 for receiving the operation switch 400. The first receiving groove 2224 may communicate with the receiving cavity 260. The depth of the first receiving groove 2224 may be much greater than the thickness of the operating switch 400, that is, after the operating switch 400 is placed in the first receiving groove 2224, a hollow cavity is formed at a position where the first receiving groove 2224 is communicated with the receiving cavity 260, so that the control area 2222 at the position of the first receiving groove 2224 is deformed. Such as: the distance between the operation switch 400 and the housing chamber 260 is about 5 mm. The length of the first receiving groove 2224 is the distance of the first receiving groove 2224 along the length direction of the side 222, and the length of the first receiving groove 2224 can be determined according to actual requirements. The width of the first receiving groove 2224 is a distance along the width direction of the side 222, and the width of the first receiving groove 2224 may be between 1.6 mm and 2 mm.

The outer surface of the side 222 may be of various shapes, such as: arc, rectangular, rounded rectangular, etc. The outer surface of the side 222 may also be curved. At least one of the rear cover 240 and the display screen 100 may be arranged in an arc shape and cover at least a portion of the side edge 222.

The operation switch 400 is provided in the control section 2222 and on the inner surface of the side 222. The operation switch 400 may be electrically connected to the circuit board 800 of the electronic device 20. The circuit board 800 of the electronic device 20 may have integrated thereon a processor, a memory, etc., which may be used to process various operations of the electronic device 20. Such as: the processor may control the display of the display screen 100 in the electronic device 20, the processor may control the camera 600 in the electronic device 20 to take a picture, and the like. The operation switch 400 may receive a control signal in the control area 2222, where the control signal may be a signal for controlling the volume of the electronic device 20, the control signal may be a signal for controlling the power on/off of the electronic device 20, and the control signal may be a signal for controlling the operating state of the camera.

In the embodiment of the present application, the operation switch 400 is disposed on the inner surface of the side 222, and the side 222 is not provided with an aperture structure for avoiding the operation switch 400, so that a user can drive the operation switch 400 through the side 222 at the position of the control area 2222 by a control signal to control the electronic device 20, such as controlling the volume of the electronic device 20, controlling the on/off of the electronic device 20, controlling the working state of a camera in the electronic device 20, and the like.

Referring to fig. 3, fig. 3 is a first structural schematic diagram of an operation switch in the electronic device shown in fig. 2. The operation switch 400 may include a pressure detection module 420, and the pressure detection module 420 may include a first flexible circuit board 422 and a pressure detector 424 electrically connected to the first flexible circuit board 422. The first flexible circuit board 422 may be disposed on an inner surface of the side 222, such as by being adhered to the inner surface of the side 222 with glue, double-sided tape, or the like. The width of the first receiving groove 2224 may be about 1.6 mm or about 2 mm.

The pressure detector 424 may include a resistive sensor or a capacitive sensor, among others. It should be noted that when the pressure detector 424 includes a capacitive sensor, no metal is disposed at the position of the pressure detector 424 to ensure the accuracy of the detection of the capacitive sensor. The resistive sensor may be a MEMS (micro electro Mechanical Systems) sensor, which requires the width of the first receiving groove 2224 to be 1.6 mm. The resistive sensor is not limited to the MEMS piezoresistive IC, and the resistive sensor may be a strain gauge, and the strain gauge needs to have a width of the first receiving groove 2224 of about 2 mm. In embodiments of the present application, the resistive sensor may be referred to as a piezoresistive sensor.

It is understood that the side 222 is thin and can be deformed by the pressing force, and the first flexible circuit board 422 and the pressure detector 424 are disposed together on the inner surface of the side 222. When the side 222 is pressed, the side 222 deforms and drives the first flexible circuit board 422 and the pressure detector 424 to deform together, and the pressure is converted into an electrical signal and transmitted to the processor of the circuit board 800, and the processor can control the electronic device 20 according to the pressing operation. The pressing operation may include one press, how many presses, long press, and the like. The long press is that the press duration exceeds the preset duration. The pressing down may be a pressing operation detected a plurality of times within a preset time.

In some embodiments, the pressing operation may be determined as the first control signal, that is, the camera 600 of the electronic device 20 may be controlled to take a picture when the operation switch 400 receives the pressing operation in the control area 2222. Therefore, the user can control the camera 600 to take a picture without touching the display screen 100, the power consumption of the touch display screen 100 can be saved, and the user operation is facilitated. Especially facilitating one-handed operation for some users. It should be noted that the operation of controlling the camera 600 of the electronic device 20 to take a picture is not limited to the pressing operation, and may be other operations.

It should be noted that, in the actual assembly process, since the first flexible circuit board 422 is made of a soft material, deformation is easily generated, and in order to reduce the deformation of the first flexible circuit board 422 in the assembly process, the thickness of the first flexible circuit board 422 may be increased. Of course, a reinforcing plate may be fixedly connected to the first flexible circuit board 422.

Referring to fig. 4, fig. 4 is a schematic diagram illustrating a second structure of the operation switch of the electronic device shown in fig. 2. The operation switch 420 may further include a reinforcing sheet 426, the reinforcing sheet 426 is fixedly connected to the first flexible circuit board 422, and the reinforcing sheet 426 and the pressure detector 424 are respectively disposed on both sides of the first flexible circuit board 422. The reinforcing sheet 426 is fixedly attached to the inner surface of the side 222 at the location of the control area 2222. The reinforcing plate 426 may increase the overall strength of the pressure detecting module 420 for assembly, thereby preventing deformation during assembly and difficulty in assembly. It should be noted that the pressure detector 424 and the reinforcing sheet 426 may not be provided on both sides of the first flexible circuit board 422.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating a third structure of the operation switch of the electronic device shown in fig. 2. The reinforcing sheet 426 and the pressure detector 424 may be disposed on the same side of the first flexible circuit board 422, the pressure detector 424 may be disposed within a gap 428 of the reinforcing sheet 426, and the space of the gap 428 is larger than the size of the pressure detector 424. Such as the thickness of the reinforcing sheet 426 is greater than the thickness of the pressure detector 424, the reinforcing sheet 426 and the pressure detector 424 do not touch. Therefore, the pressure detector 424 is ensured not to contact with the reinforcing sheet 426 or the side edge 222 when being deformed by the pressure, so that the accuracy of the pressure detector 424 for detecting the pressing force is affected.

It will be appreciated that in order for the pressure detector 424 to be able to effectively detect pressure, a void 428 may be provided in the reinforcing sheet 426, with the pressure detector 424 being spatially located within the void 428. Therefore, when the side 222 of the control area 2222 receives the acting force, the stress of the acting force is applied to the pressure detector 424 at the position of the gap 428 due to the arrangement of the reinforcing sheet 426, so that the signal detected by the pressure detection module 420 can be more accurate. In some embodiments, two reinforcing sheets 426 may be connected to the first flexible circuit board 422 to form the gap 428, or a gap 428 may be opened on one reinforcing sheet 426.

It should be noted that the accuracy of the signal detected by the pressure detecting module 420 can be improved without providing the reinforcing sheet 426, such as providing a groove on the side 222 of the control area 2222 to locate the pressure detector 424 in the groove, so that the thickness of the two sides of the groove is larger, and thus the thickness of the position of the pressure detector 424 is smaller, and the deformation is also easy to occur.

It should be noted that the pressure detection module 420 may also detect other operations, such as a sliding operation. The pressure detection module 420 may determine that it is continuously moving based on the pressure it detects.

The pressure detection module 420 may also control the focusing of the camera 600 according to the control signal. Such as the pressure detecting module 420 detecting the gradual increase of the pressure and determining it as the second control signal for transmission to the processor of the circuit board 800, and the processor can adjust the focal length of the camera 600 according to the second control signal. Of course, the operation of controlling the adjustment of the focal length of the camera 600 may also be other operations, such as a sliding operation or the like. It should be noted that the operation of controlling the camera 600 to take a picture and the operation of adjusting the focal length of the camera 600 are different.

Referring to fig. 6, fig. 6 is a fourth structural diagram of the operation switch of the electronic device shown in fig. 2. The operation switch 400 may further include an ultrasonic detection module 440, and the ultrasonic detection module 440 may include a second flexible circuit board 442, a signal transmitting part 444, and a signal receiving part 446. The signal transmitting portion 444 and the signal receiving portion 446 are electrically connected to the second flexible circuit board 442. The signal transmitting portion 444 and the signal receiving portion 446 may be made of a piezoelectric ceramic material. The second flexible circuit board 442 may be disposed on an inner surface of the side 222 of the control area 2222, such as by being adhered to the inner surface of the side 222 with glue, double-sided tape, or the like. The ultrasonic detection module 440 may receive different signals, such as different operation modes, and may determine the control signal according to the operation mode to control the functions of the electronic device 20 according to the control signal.

The ultrasonic detection module 440 can detect the pressed position of the control area 2222 to achieve positioning. Or the ultrasonic detection module 440 can detect a specific position for the finger to be placed in the control area 2222, so as to realize the positioning. When the pressing force continuously moves, or the user's finger slides in the control area, the ultrasonic detection module 440 receives the sliding operation signal, and determines the sliding operation signal as a second control signal, and converts the second control signal into an electrical signal and transmits the electrical signal to the processor of the circuit board 800, and the processor can adjust the focal length of the camera 600. Thereby realizing the adjustment of the focal length of the camera 600. It should be noted that the ultrasonic detection module 440 may also control the focusing of the camera 600 according to other detected operations. It should be further noted that the ultrasonic detection module 440 can control the camera 600 to take a picture and focus respectively according to two different sliding operations. Such as the sliding distance of the first sliding operation being less than the sliding distance of the second sliding operation.

It is understood that other operations, such as a tap, may also be detected by the ultrasonic detection module 440. The ultrasonic detection module 440 may also control other functions of the electronic device 20 according to other operations or different sliding operations. Wherein the sliding direction of the sliding operation is along the length of the side 222.

It is understood that a signal transmitting portion 444 and a signal receiving portion 446 may be disposed at an interval on the ultrasonic detection module 440. A plurality of signal transmitting sections 444 and a plurality of signal receiving sections 446 may be provided at intervals.

The operation switch 400 is not limited to the ultrasonic detection module 440 and the pressure detection module 420. In some embodiments, the operation switch 400 may include a pressure detection module and an ultrasonic detection module. Such as disposing the pressure detector, the ultrasonic-wave signal transmitting section, and the ultrasonic-wave signal receiving section on the same flexible circuit board. For example: a pressure detector is disposed between a signal transmitting portion and a signal receiving portion. Of course, if the pressure detector is plural, each pressure detector is disposed between one signal transmitting portion and one signal receiving portion. The operation switch 400 includes both a pressure detector by which a degree of pressing can be effectively detected and an ultrasonic detector by which a pressed position can be effectively detected. Thereby, not only functions of the electronic device 20 such as controlling the camera 600 to take a picture, and controlling the camera 600 to focus can be accurately controlled according to the received signals. Meanwhile, the function of preventing mistaken touch can be realized according to the pressing intensity and the pressing position.

It should also be noted that the electronic device 20 may also be provided with one or more ultrasonic detectors and one or more pressure detectors in different control areas 2222.

Referring to fig. 7, fig. 7 is another partial sectional view of the electronic device shown in fig. 1 along a direction P2-P2. The electronic device 20 may further include a touch detection module 300, and the touch detection module 300 may be disposed between the side 222 and the rear cover 240. The side 222 may further include a detection area 2226, the detection area 2226 may be disposed adjacent to the control area 2222, the control area 2222 may be a middle position of the side 222, and the detection area 2226 may be located outside the middle position. Such as detection zone 2226, is located on a side adjacent to rear cover 240. The touch detection module 300 may be adjacent to the rear cover 240, or may be disposed between the rear cover 240 and the side 222, so as to be covered by the rear cover 240 for protection. The operation switch 400 may be located between the touch detection module 300 and the display screen 100.

The touch detection module 300 may be a capacitive detector, and the rear cover 240 may be made of glass. The capacitance detector is an electrode plate with a certain shape, under the condition that no finger touches the surface of the sensor, a certain capacitance (self-capacitance) is formed between the electrode plate and the surrounding ground, when the finger touches the surface of the sensor, the conductive property and the large mass of a human body form a grounded conductive layer, so that electric field lines are formed, and the capacitance between the capacitance detector and the ground is changed. By detecting this change in capacitance, it is possible to know whether there is a finger press. Thereby, the function of preventing the erroneous touch is realized through the touch detection module 300. It should be noted that the capacitive detector can refer to the touch function of the display screen.

The processor on the circuit board 800 of the electronic device 20 can control the electronic device 20 according to the detection result of the touch detection module 300 and the detection result of the pressure detection module 420. Of course, the processor may control the electronic device 20 only according to the detection result of the pressure detection module 420, or may control the electronic device 20 according to the detection result of the touch detection module 300. The detection result of the touch detection module 300 may include a sliding operation, and the processor may control the camera 600 of the electronic device 20 to take a picture, focus, and the like according to the sliding operation.

It should be noted that, when the touch detection module 300 is adjacent to the rear cover 240, the touch detection module 300 may be covered on the capacitance detector through a touch cover plate, the touch cover plate may be connected with the rear cover 240 in a matching manner, and the touch cover plate may protect the capacitance detector. When the detection area 2226 of the side 222 has an arc-shaped structure, the capacitive detector may be disposed on a third flexible circuit board, and the third flexible circuit board may be disposed on the side 222 at the position of the detection area 2226 of the arc-shaped structure. The corresponding touch cover or the back cover 240 may be disposed in an arc shape corresponding to the touch detection module 300 and corresponding to the arc structure of the side 222. The touch detection module 300 may be directly disposed on the outer surface of the side 222, or a second receiving groove may be formed on the side 222 for receiving the touch detection module 300.

Wherein the side edges such as the side edges 222, the pressure detection module such as the pressure detection module 420, and the touch detection module such as the touch detection module 300 may form a housing assembly. In the housing assembly, the pressure detection module 420 is disposed in the control area 2222 of the side 222, and the touch detection module 300 is disposed in the detection area 2226 of the side 222. The pressure detection module 420 can detect whether the control area 2222 has a pressing operation, and the touch detection module 300 can determine whether the detection area 2226 has a touch operation. The touch operation may include a sliding operation, and the like. It should be noted that the housing assembly can be applied to the electronic device 20. The housing assembly may also include an ultrasonic detection module such as ultrasonic detection module 440. The operation position of the control area 2222 of the side 222 can be detected by the ultrasonic detection module 440.

It will be appreciated that due to the limited width of the side 222, a user's finger pressing on the control area 2222 of the side 222 will tend to press a portion of the finger against the rear cover 240 and possibly the display screen 100. In the embodiment of the application, the detection area 2226 is disposed at a position on one side of the control area 2222 and a position on one side of the rear cover 240 to install the touch detection module 300, so that whether a user presses a finger can be determined, and the anti-false-touch operation switch 400 can be further implemented.

It should be noted that the user often touches the touch operation switch 400 to make the display screen 100 in a bright state, and can also detect whether the display screen 100 has a touch operation according to the display screen 100, and if the display screen 100 has a touch operation, the function of preventing a false touch can be further improved, so as to achieve more accurate control over the operation switch 400.
