[0040] like Figure 1As shown, the present application provides an embodiment of an electronic device accessory. The electronic device accessory 100 of the present application is used to be installed on an electronic device 200. A sensor for triggering code scanning is provided in the electronic device 200. When the sensor detects a change in the magnetic field, a code scanning instruction can be sent to the processor to complete the code scanning. The sensor can be a Hall sensor or a reed switch sensor. The Hall sensor can detect the magnetic field generated by a magnetic part (such as a magnet or a permanent magnet). When the magnetic part approaches or moves away from the Hall sensor, the magnetic field strength detected by the Hall sensor will change, thereby triggering an output signal. The reed switch sensor, also known as a reed switch or reed relay, is a passive switch sensor based on the reed switch principle. It consists of two main parts: two magnetic contacts (usually made of iron-nickel alloy) sealed in a vacuum glass tube, and an external magnetic part (magnetic field source), such as a permanent magnet or an electromagnet. When the magnetic part is away from the reed switch sensor, that is, when there is no magnetic field, the two magnetic contacts in the tube are separated, the circuit is in an open state, and the code cannot be scanned. When a magnetic part (magnetic field source) approaches the reed switch sensor, the two magnetic contacts in the tube will be magnetized and attracted together, thereby closing the circuit and realizing the state change from open to closed.

[0041] The electronic device accessory 100 can be detachably connected to the electronic device 200. When the electronic device 200 needs to perform operations such as scanning a code, the electronic device accessory 100 can be installed on the back of the electronic device 200. When the electronic device 200 does not need to perform operations such as scanning a code, the electronic device accessory 100 can be removed from the electronic device 200 so that the electronic device 200 can be used as an ordinary tablet computer. The electronic device accessory 100 and the electronic device 200 can be detachably connected by connecting methods such as magnetic attraction or snaps. The overall size (area) of the electronic device accessory 100 is smaller than the overall size (area) of the electronic device 200. The size of the electronic device accessory 100 can be set to a size that is convenient for the user to hold, so that the user can hold the electronic device accessory 100 and operate the electronic device accessory 100.

[0042] like Figures 2 to 5 As shown, the electronic device accessory 100 includes an accessory housing 110, a magnetic component 120, a button 130 and a connecting rod 140; the magnetic component 120 is arranged in the accessory housing 110 and can reciprocate between a first position and a second position in the accessory housing 110, and the magnetic component 120 can be a magnet or a permanent magnet; the button 130 is movably arranged in the accessory housing 110; one end of the connecting rod 140 is hinged to the magnetic component 120, and the other end of the connecting rod 140 is hinged to the button 130; in the initial state, the magnetic component 120 is located in the first position, and the sensor 210 does not trigger the code scanning; when the button 130 is pressed, the connecting rod 140 drives the magnetic component 120 to move to the second position, and the sensor 210 triggers the code scanning; when the button 130 is released, the magnetic component 120 resets to the first position.

[0043] After the electronic device accessory 100 is installed on the electronic device 200, the user holds the electronic device accessory 100. When the electronic device 200 needs to scan a code, the user can press the button 130 on the electronic device accessory 100 with one hand to rotate the connecting rod 140. When the connecting rod 140 rotates, it drives the magnetic member 120 to move in the direction from the first position to the second position, so that the magnetic member 120 moves to the second position, and the sensor 210 is facing the second position in the accessory housing 110, that is, the magnetic member 120 is close to the sensor 210. At this time, the sensor 210 senses the change in magnetic field strength and triggers the electronic device 200 to scan the code. After the code scanning is completed, the user can release the button 130, and the magnetic member 120 resets to the first position. The sensor 210 detects that the magnetic field strength is reduced or the magnetic field cannot be detected, triggering the electronic device 200 to turn off the code scanning function.

[0044] In the present application, a smaller electronic device accessory 100 is installed on the electronic device 200, and a movable magnetic part 120 and a button 130 are provided on the electronic device accessory 100. When the user holds the electronic device accessory 100, the user can directly press the button on the accessory housing 110 to drive the magnetic part 120 to move to trigger the electronic device 200 to complete the code scanning. This can solve the problem that electronic devices 200 such as tablet computers cannot scan codes with one hand due to their large size. It is not only convenient and quick to operate, but also provides a good user experience and sense of technology.

[0045] Furthermore, after the electronic device accessory 100 is installed on the electronic device 200, when the user holds the electronic device accessory 100 to scan a code, in order to prevent the electronic device 200 from falling, a hand strap can be provided on the electronic device accessory 100 to prevent the electronic device 200 from falling. When scanning a code is required, pressing the button 130 with one hand can drive the magnetic part 120 to move, so that the magnetic part 120 and the sensor 210 generate induction to complete the code scanning. After the code scanning is completed, releasing the button 130 can stop the code scanning, so that the entire code scanning process of the electronic device 200 can be completed with one hand.

[0046] In one embodiment, Figure 2 and Figure 3As shown, a slide rail 150 is provided in the accessory housing 110, and the slide rail 150 extends from the first position to the second position. The magnetic member 120 is movably provided on the slide rail 150, and the magnetic member 120 moves along the slide rail 150. The slide rail 150 can limit the moving direction of the magnetic member 120. The bottom of the slide rail 150 is fixed in the accessory housing 110, and the two side walls of the slide rail 150 that are oppositely arranged along the width direction are respectively provided with grooves 151, and the grooves 151 extend along the length direction of the slide rail 150, and the length direction of the slide rail 150 is the extension direction of the slide rail 150. The magnetic member 120 moves along the length direction of the slide rail 150, and the width direction of the slide rail 150 is perpendicular to the length direction of the slide rail, and the height direction of the slide rail 150 is consistent with the height direction of the electronic device 200. The magnetic member 120 includes a magnetic member body 121 and two sliding parts 122. The two sliding parts 122 are arranged on two opposite sides of the magnetic member body 121. The sliding part 122 includes a vertical part and a horizontal part. One end of the vertical part is connected to the magnetic member body 121, and the other end of the vertical part is connected to the horizontal part. The horizontal part extends into the groove 151 and can move in the groove 151 along the extension direction of the groove 151.

[0047] Furthermore, it also includes a slider 160, which is movably arranged on the slide rail 150 along the extension direction of the slide rail 150, the slider 160 is fixedly connected to the magnetic member 120, and the end of the connecting rod 140 away from the button 130 is hinged to the slider 160. When the connecting rod 140 rotates, it drives the slider 160 to move along the slide rail 150, and when the slider 160 moves along the slide rail 150, it drives the magnetic member 120 to move along the slide rail 150.

[0048] In other embodiments, a slide groove may be further provided in the accessory housing 110, and the slide groove extends in the direction from the first position to the second position. The magnetic component 120 may be movably disposed in the slide groove, and the magnetic component 120 moves in the slide groove. The slide groove may also limit the moving direction of the magnetic component 120.

[0049] In one embodiment, Figure 3As shown, the electronic device accessory 100 further includes a first elastic member 170, one end of which is connected to the magnetic member 120 or the slider 160, and the other end of the first elastic member 170 is connected to the accessory housing 110, for resetting the magnetic member 120 to the first position. In one example, when the magnetic member 120 is in the first position, the first elastic member 170 is in a natural state, and when the button 130 is pressed, the connecting rod 140 drives the magnetic member 120 to move and overcome the elastic force of the first elastic member 170, and when the magnetic member 120 moves to the second position, the first elastic member 170 is in a stretched state, and after releasing the button 130, the first elastic member 170 is reset, so that the magnetic member 120 is reset to the first position. In another example, when the magnetic member 120 is in the first position, the first elastic member 170 is in a natural state, and when the button 130 is pressed to move the magnetic member 120 to the second position, the first elastic member 170 is in a compressed state, and after the button 130 is released, the first elastic member 170 is reset to reset the magnetic member 120 to the first position. The first elastic member 170 can be a spring, a spring sheet, etc.

[0050] In one embodiment, the electronic device accessory 100 further includes a second elastic member, one end of which is connected to the button 130, and the other end of which is connected to the accessory housing 110, for resetting the button 130. When the button 130 is pressed, the second elastic member is in a compressed state, and when the button 130 is released, the second elastic member is reset and the button 130 is reset. When the second elastic member is not provided, when the magnetic member 120 is reset under the action of the first elastic member 170, it can also drive the button 130 to reset; after the second elastic member is provided, when the button 130 is reset under the action of the second elastic member, it can also drive the magnetic member 120 to reset, that is, the magnetic member 120 can be reset under the dual elastic force of the first elastic member 170 and the second elastic member, thereby improving the reset accuracy of the magnetic member 120.

[0051] In one embodiment, when the magnetic member 120 is in the first position, the sensor 210 is disconnected from the magnetic member 120; when the magnetic member 120 is in the second position, the sensor 210 is inductively coupled to the magnetic member 120. When the sensor 210 is disconnected from the magnetic member 120, no code scanning instruction is sent or the circuit is disconnected, and the electronic device 200 is disconnected from scanning; when the sensor 210 is inductively coupled to the magnetic member 120, the sensor 210 generates a code scanning instruction or the circuit is closed, and the electronic device 200 starts the code scanning function and completes the code scanning.

[0052] The sensor 210 disconnects the induction or generates the induction with the magnetic part 120, which can be achieved by the material of the accessory housing 110 or the housing of the electronic device 200. Exemplarily, the accessory housing 110 includes a plastic accessory housing area and a metal accessory housing area, the first position corresponds to the metal accessory housing area, and the second position corresponds to the plastic accessory housing area. The area outside the plastic accessory refers to the area where the accessory housing 110 is made of plastic, and the area outside the metal accessory housing refers to the area where the accessory housing 110 is made of metal; when the magnetic part 120 moves to the first position, that is, the magnetic part 120 moves to the area where the accessory housing 110 is made of metal, at this time, the metal material has a shielding effect, which can disconnect the magnetic field induction between the sensor 210 and the magnetic part 120, so that the sensor 210 will not send a code scanning instruction or will not trigger the code scanning, and the electronic device 200 will not turn on the code scanning function or turn off the code scanning function; when the magnetic part 120 moves to the second position, that is, the magnetic part 120 moves to the area where the accessory housing 110 is made of plastic, at this time, a magnetic field induction is generated between the sensor 210 and the magnetic part 120, and the sensor 210 sends a code scanning instruction to complete the code scanning or trigger the code scanning. In this embodiment, the sensor 210 can be a Hall sensor or a reed switch sensor. Figure 4 As shown, when the magnetic member 120 is in the first position, the magnetic member 120 and the sensor 210 are staggered. Figure 5 As shown, when the magnetic member 120 is in the second position, it corresponds to the sensor 210. In other embodiments, a plastic area and a metal area may be provided on the housing of the electronic device 200 to disconnect the sensor 210 from the magnetic member 120 or generate induction, so as to realize turning off or on the code scanning function.

[0053] In one embodiment, when the magnetic member 120 is in the first position, the sensor 210 detects a first magnetic field; when the magnetic member 120 is in the second position, the sensor 210 detects a second magnetic field, and the magnetic field strength of the second magnetic field is greater than the magnetic field strength of the first magnetic field. In this embodiment, the sensor 210 can turn on or off the code scanning function by detecting the change in magnetic field strength. For example, Figure 4 As shown, when the magnetic member 120 is in the first position, the magnetic member 120 is far away from the sensor 210, the magnetic field strength detected by the sensor 210 is small, and the sensor 210 does not send a code scanning instruction or trigger a code scanning function; Figure 5 As shown, when the magnetic member 120 is in the second position, the magnetic member 120 is closer to the sensor 210, the magnetic field strength detected by the sensor 210 is larger, and the sensor 210 generates a code scanning instruction or triggers a code scanning function. In this embodiment, the sensor 210 can be a Hall sensor or a reed switch sensor.

[0054] In one embodiment, Figure 3As shown, there are two buttons 130 and two connecting rods 140, two connecting rods 140 are arranged on both sides of the magnetic member 120 and one end is respectively hinged to the magnetic member 120, and the other ends of the two connecting rods 140 are respectively hinged to the two buttons 130, and the connecting line of the two buttons 130 is perpendicular to the moving direction of the magnetic member 120 and arranged along the width direction of the slide rail 150. The two buttons 130 are respectively arranged on both sides of the accessory housing 110 along the width direction, and when the user holds the electronic device accessory 100, the distance between the two buttons 130 is adapted to the distance between the user's thumb and index finger, so that the user can press the two buttons 130 at the same time with one hand, which is convenient for the user to operate.

[0055] The present application also provides an embodiment of an electronic device component, such as Figures 1 to 5 As shown, the electronic device 200 and the electronic device accessory 100 described in any of the above embodiments are included, the electronic device 200 includes a device housing 220 and a sensor 210 disposed in the device housing 220, the electronic device accessory 100 is detachably connected to the device housing 220, the size of the accessory housing 110 is smaller than the size of the device housing 220, and when the electronic device accessory 100 is installed on the device housing 220, the sensor 210 corresponds to the second position. The sensor 210 is a Hall sensor or a reed switch sensor.

[0056] In the mobile ordering / payment scenario, the user holds the electronic device accessory 100 with one hand and uses the wrist strap to prevent the electronic device 200 from falling. When scanning a code is needed, the user presses the button 130 with one hand, and the connecting rod 140 pushes the magnetic part 120 to move to the second position. When reaching this position, the magnetic part 120 and the sensor 210 generate induction to send a scanning instruction to complete the scanning. When the left and right buttons 130 are released, the first elastic part 170 and / or the second elastic part will cause the magnetic part 120 to move downward to the first position to disconnect the magnetic field induction, thereby disconnecting the scanning and completing the scanning process of the entire electronic device 200 with one hand.

[0057] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0058] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
