[0051] Based on this, the embodiments of the present application provide an accessory of a digital equipment, by additionally providing a display screen in the accessory, thereby meeting the personalized needs of the user and improving the user experience.

[0052] The following will be described in detail. It should be noted that the order of the following embodiments is not limited as the preferred order of the embodiments.

[0053] According to a first aspect of the present application, with reference to Figure 1 and Figure 2The utility model embodiment provides a kind of accessory 2 of digital device 1, comprising:

[0054] Connecting piece 21, connecting piece 21 is used to connect to the interface 11 of digital device 1;

[0055] Display screen 22, display screen 22 is installed to connecting piece 21;And,

[0056] Passive drive circuit 23, passive drive circuit 23 is electrically connected with display screen 22, for converting the energy in environment into electric energy, and power supply is displayed to screen 22.

[0057] Connecting piece 21 is generally made of high-strength engineering plastics, with good insulation, heat resistance and mechanical strength, so that connecting piece 21 can withstand a certain degree of external force pulling and extrusion without damage, improve service life.Connecting piece 21 is usually provided with the structure matched with the interface 11 of digital device 1, and the type of interface 11 on digital device 1 can be set specifically.For example, if interface 11 is set as convex nature, a groove can be set on connecting piece 21 correspondingly, and the connection of connecting piece 21 and digital device 1 is realized by the cooperation between convex and groove;if interface 11 is magnetic attraction structure, metal or magnet that can be magnetically attracted can be provided on connecting piece 21, so that connecting piece 21 and digital device 1 are connected by magnetic attraction.The size and shape of connecting piece 21 can be selected according to design needs, if the digital device 1 installed with the accessory 2 is smaller, the size of connecting piece 21 can be controlled to be smaller;if more components need to be set on connecting piece 21, the size of connecting piece 21 can be controlled to be larger;The utility model does not limit this.

[0058] Display screen 22 is a common display structure, and the screen size can be determined according to the size of connecting piece 21 and the type of target digital device 1.The connection mode of display screen 22 and connecting piece 21 has many kinds, for example, the outer surface of connecting piece 21 can be set as a plane, so that display screen 22 can be installed on the outer surface of connecting piece 21 by bonding;Buckling structure can be provided on connecting piece 21, and clamping groove structure is provided at the corresponding position of display screen 22, so that the two can be connected by clamping.In an alternative embodiment, display screen 22 can be set as ink screen, so that the power consumption of display screen 22 is less, and the endurance time is longer.

[0059] Passive drive circuit 23 can be arranged inside connecting piece 21, for power supply to display screen 22.Exemplarily, referring to Figure 3 Passive drive circuit 23 can include antenna circuit, communication circuit, microprocessor and power supply circuit.Antenna circuit can be wirelessly connected with external equipment such as mobile phone.Communication circuit is connected with antenna circuit, microprocessor is connected with communication circuit, and microprocessor wirelessly communicates with external equipment such as mobile phone through communication circuit and antenna circuit.

[0060] The power supply circuit is connected with the antenna circuit to convert the energy in the environment into electric energy through the antenna circuit. The power supply circuit includes a matching circuit, a rectifier circuit and an energy storage circuit. The matching circuit is connected with the antenna circuit and cooperates to output first electric energy. The rectifier circuit is connected with the matching circuit and rectifies the first electric energy. The energy storage circuit is connected with the rectifier circuit and stores the rectified first electric energy. The energy storage circuit is used to be connected with the display screen 22 and supply power for the display screen 22 when the display screen 22 updates the display content.

[0061] The power supply circuit is connected with the antenna circuit and can obtain electric energy through the antenna circuit to supply power for the display screen 22 when the display screen 22 updates the display content. The passive driving circuit 23 directly obtains electric energy from the external device, and does not need to set a battery, so there is no problem that the display screen 22 cannot update the display content when the battery is used up, and the use is more convenient. The power supply circuit includes a matching circuit, a rectifier circuit and an energy storage circuit connected in sequence. The matching circuit and the antenna circuit can better obtain the radio frequency signal of the external device. The rectifier circuit can rectify the first electric energy output by the matching circuit, and facilitate the energy storage circuit to store electric energy.

[0062] In addition, the display screen 22 is powered by the energy storage circuit, and does not need to set a battery, so the thickness of the passive driving circuit 23 can be reduced, and the passive driving circuit 23 can be more conveniently arranged in the accessory 2. The microprocessor and the communication circuit can communicate with the external device wirelessly through the antenna circuit, such as obtaining a data signal. The display screen 22 can update the display content according to the data signal, and can conveniently obtain the data signal corresponding to the new image, so as to facilitate the display screen 22 to update the display content.

[0063] In use, when the accessory 2 is connected to the digital device 1, the connecting piece 21 first establishes physical connection between the interface 11 of the digital device 1, so that the accessory 2 is stably installed on the digital device 1. Then the user can control the display screen 22 to display different patterns or characters, so as to meet the personalized needs of the user. In an optional embodiment, the connecting piece 21 can also establish a communication connection with the digital device 1, so that the user can indirectly control the display screen 22 by controlling the digital device 1, thereby reducing the operation difficulty of the user.

[0064] In the embodiment of the utility model, through setting display screen 22 on connecting piece 21 of accessory 2 of digital device 1, when using accessory 2 in the utility model, user can show various patterns through display screen 22, thereby satisfying personalized demand of user, improve use experience of user.

[0065] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 4 , connecting piece 21 includes mounting portion 211 and connecting portion 212, at least one side of mounting portion 211 is provided with connecting portion 212, connecting portion 212 is used for matching with interface 11, so that connecting piece 21 is fixed to interface 11, and display screen 22 is installed on mounting portion 211.

[0066] Mounting portion 211 is a support structure, and the shape and size thereof are set according to actual needs. Connecting portion 212 is arranged on one side of mounting portion 211, thereby increasing the contact area with interface 11, so that the connection between connecting piece 21 and interface 11 is more close, and accessory 2 in the embodiment of the utility model is prevented from falling off from interface 11.

[0067] Connecting portion 212 can be arranged only on one side of mounting portion 211, or can be arranged on multiple sides of mounting portion 211. The shape of connecting portion 212 is matched with interface 11, thereby ensuring the stability of the connection between connecting portion 212 and interface 11. For example, connecting portion 212 can be a continuous whole, or can be composed of multiple parts arranged at intervals, and the utility model does not limit this.

[0068] The connecting part 212 can be connected with the interface 11 in various modes, and the mode can be set according to design requirements. For example, if the interface 11 is a groove structure, the connecting part 212 can be a protruding structure matched with the groove shape. At this time, the connecting part 212 can be arranged on each of the plurality of circumferential sides of the mounting part 211, so that the connecting part 212 is matched with the interface 11, and the mounting part 211 is located at the middle position of the connecting part 212, thereby improving the stability of the connecting piece 21. If the interface 11 is a threaded hole structure, the connecting part 212 can be a columnar structure provided with external threads, so that the connecting piece 21 and the interface 11 are threadedly connected. It can be understood that the connecting part 212 is usually arranged at the bottom end of the mounting part 211, so as to be connected with the interface 11 of the digital device 1. The display screen 22 is usually arranged at the top end of the mounting part 211, so as to reduce the probability that the display screen 22 is blocked by the digital device 1 and facilitate the user to watch the content displayed on the display screen 22.

[0069] In some embodiments, with reference to Figure 5 and Figure 6 , the mounting part 211 comprises: a main body 2111, the outer circumferential side of the main body 2111 is provided with the connecting part 212; and an extension part 2112, the extension part 2112 protrudes from the outer circumferential side of the main body 2111; wherein the display screen 22 is partially located on the main body 2111 and partially located on the extension part 2112.

[0070] The main body 2111 is used to bear the connecting part 212 and the extension part 2112, and the size and shape thereof can be set as required. The extension part 2112 is a structure protruding from the main body 2111 and is used to expand the display screen 22, so that the installation of the display screen 22 is not limited to the main body 2111, that is, the size of the display screen 22 can be further increased, thereby improving the viewing experience of the user. For example, the main body 2111 is in the shape of a cuboid, and the outer circumferential side of the main body 2111 comprises four side surfaces 2114. The extension part can be located on any one or more of the four side surfaces 2114, thereby facilitating the installation of a larger display screen 22. Optionally, the extension part can be arranged at the end of the main body 2111, so that the upper surface of the main body 2111 and the upper surface of the extension part are at the same horizontal plane, thereby facilitating the installation of a flat display screen 22.

[0071] The main body 2111 and the extension part 2112 can be connected in various modes, such as bonding, welding and other non-detachable connection modes, or threaded connection, clamping or magnetic connection and other detachable connection modes, and the utility model does not limit this.

[0072] In some embodiments, with reference to Figure 1 , Figure 6 and Figure 7 , the interface 11 comprises a first groove 111, and at least one limiting piece 112 is protruded from the inner wall of the first groove 111; wherein

[0073] The extension part 2112 is arranged apart from the connecting part 212 to form a sliding groove 213 between the extension part 2112, the connecting part 212 and the mounting part 211, the sliding groove 213 being used for sliding connection with the limiting part 112; and / or,

[0074] The connecting part 212 is used for being inserted between the limiting part 112 and the inner wall of the first groove 111.

[0075] In order to make the connection between the interface 11 and the accessory 2 more compact, the limiting part 112 is usually arranged in the first groove 111 of the interface 11, so as to limit the accessory 2 and reduce the probability of the accessory 2 coming out of the interface 11. In contrast, in an embodiment of the present application, the extension part 2112 and the connecting part 212 on the main body 2111 are arranged apart from each other, so that the extension part 2112, the connecting part 212 and the mounting part 211 enclose a sliding groove 213. By adjusting the distance between the extension part 2112 and the connecting part 212, the limiting part 112 can be accommodated in the sliding groove 213 and can slide in the sliding groove 213. Optionally, the size of the sliding groove 213 can be slightly larger than the size of the limiting part 112, so that after the interface 11 and the accessory 2 are connected, the limiting part 112 and the sliding groove 213 can be locked with each other, further reducing the probability of the accessory 2 coming out of the interface 11.

[0076] In another embodiment of the present application, since the limiting part 112 is arranged in the first groove 111, the limiting part 112 and the inner wall of the first groove 111 also enclose a sliding groove. At this time, the size of the connecting part 212 can be controlled so that the connecting part 212 can cooperate with the sliding groove, thereby further increasing the stability of the connection between the interface 11 and the accessory 2. Optionally, the size of the connecting part 212 can be slightly smaller than the size of the sliding groove, so that after the interface 11 and the accessory 2 are connected, the connecting part 212 and the sliding groove can be locked with each other, further reducing the probability of the accessory 2 coming out of the interface 11. It can be understood that the cooperation between the limiting part 112 and the sliding groove 213 and the cooperation between the connecting part 212 and the sliding groove can be realized at the same time, so that the connection between the accessory 2 and the interface 11 is more compact.

[0077] In some embodiments, referring to Figure 5 and Figure 6 The main body 2111 includes a first side 21111 and a second side 21112 arranged opposite to each other, wherein,

[0078] The number of the connecting part 212 and the extension part 2112 is at least two, and the first side 21111 and the second side 21112 are both provided with the connecting part 212; and / or, in the direction from the first side 21111 to the second side 21112, the size of the display screen 22 is D1, and 10mm≤D1≤25mm.

[0079] It should be noted that, in the embodiments of the present application, the association relationship of the associated objects described by "and / or" represents that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone.

[0080] The connecting portion 212 is arranged on the opposite sides of the main body 2111, so that the two ends of the accessory 2 can be matched with the interface 11, thereby improving the stability of the connection between the accessory 2 and the interface 11. The extending portion 2112 is arranged on the opposite sides of the main body 2111, so that the display screen 22 can be conveniently installed in the middle of the accessory 2, thereby ensuring the coordination between the accessory 2 and the digital device 1 and improving the viewing experience of the user.

[0081] The size of the display screen 22 can be set according to the size of the interface 11 of the digital device 1. For example, the width of the interface 11 on the camera in the direction from the first side 21111 to the second side 21112 is usually less than 25 mm. Therefore, in the embodiment, the size D1 of the display screen 22 is set to be between 10 mm and 25 mm. If D1 is greater than 25 mm, the width of the display screen 22 is usually greater than the width of the hot shoe interface 11, thereby increasing the probability that the display screen 22 is damaged due to collision. If the size D1 of the display screen 22 is less than 10 mm, the pattern that can be displayed to the user is small, and the viewing experience is poor. Controlling D1 to be between 10 mm and 25 mm can ensure that the display screen 22 is not easily damaged, and the accessory 2 can also play a good decorative role. For example, D1 can be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, etc., and the embodiments of the present application do not limit this.

[0082] In some embodiments, with reference to Figure 2 , Figure 6 and Figure 8 , the mounting portion 211 comprises a top surface 2113 and a side surface 2114 connected by bending, the connecting portion 212 is protrudingly arranged on the side surface 2114, the mounting portion 211 is further provided with a receiving groove 2115 with an opening on the top surface 2113, and the display screen 22 is installed in the receiving groove 2115.

[0083] The display screen 22 is installed more simply by forming the accommodating groove 2115 on the top surface 2113, the accommodating groove 2115 is arranged on the top surface 2113 of the mounting portion 211, and the user is more convenient to watch the display screen 22, thereby improving the decoration of the accessory 2 on the digital device 1. The size and shape of the accommodating groove 2115 can be arranged according to the size and shape of the display screen 22, for example, the accommodating groove 2115 can be cylindrical or prismatic, and the upper surface of the display screen 22 after installation can be on the same horizontal plane as the upper surface of the sidewall of the accommodating groove 2115, so that the appearance of the accessory 2 is more neat, and the display screen 22 is not easily damaged.

[0084] In some embodiments, with reference to Figure 8 The connecting piece 21 further comprises a baffle 24, the mounting portion 211 and the connecting portion 212 are connected to the baffle 24, and the baffle 24 is used to limit the depth of the accessory 2 inserted into the interface 11.

[0085] The interface 11 generally comprises a groove, thereby facilitating the insertion of the accessory 2 into the groove. In order to prevent the accessory 2 from moving too long distance and causing the accessory 2 to be not installed in place, a baffle 24 is arranged in the embodiment to connect the mounting portion 211 and the connecting portion 212, so that after the mounting portion 211 and the connecting portion 212 are deeply inserted into the groove by a certain distance, the baffle 24 abuts against the opening end of the groove, thereby blocking the continuous movement of the mounting portion 211 and the connecting portion 212, and ensuring that the accessory 2 is installed in the appropriate position. It can be understood that a protruding portion can be protruded on at least one of the side surfaces 2114 of the baffle 24, so as to limit the movement stroke of the accessory 2, and when the user needs to disassemble the accessory 2, the protruding portion can also be used to exert force, thereby moving the accessory 2 in the reverse direction until the accessory 2 is separated from the interface 11.

[0086] In some embodiments, the passive driving circuit 23 comprises an antenna, and the antenna is used to communicate with an external device.

[0087] In some embodiments, the antenna can comprise a QI coil, an NFC (Near Field Communication) coil, a Bluetooth antenna, and the like, and the embodiments of the present application do not limit this.

[0088] The antenna comprises a coil formed by winding an enameled wire.

[0089] In some embodiments, the antenna comprises a coil formed by winding an enameled wire.

[0090] It can be understood that in the related art, a coil is usually formed on the surface of a flexible circuit board by a copper layer with a relatively small thickness, so that the thickness of the coil formed on the surface of the flexible circuit board is less than 10 microns. In the case that the thickness of the coil formed on the surface of the flexible circuit board is small, the energy transmission efficiency between the antenna and the mobile terminal is low.

[0091] In contrast, in the embodiments of the present application, the diameter of the enameled wire used to form the coil is generally greater than the thickness of the coil formed on the surface of the flexible circuit board. For example, the diameter of the enameled wire can be greater than or equal to 150 microns. Therefore, the coil formed by winding the enameled wire can effectively improve the energy transmission efficiency between the antenna and the mobile terminal.

[0092] In some embodiments, the diameter of the enameled wire can be 150 to 230 microns. Thus, it can ensure that the enameled wire has a large enough diameter to ensure that the coil has good energy transmission efficiency, and it can also avoid that the diameter of the enameled wire is too large, which causes the coil to be too large and makes the mobile terminal protective shell as a whole too thick and heavy.

[0093] For example, the diameter of the enameled wire can be 150 microns, 154 microns, 155 microns, 160 microns, 161.07 microns, 165.5 microns, 168.7 microns, 170 microns, 180 microns, 195 microns, 200 microns, 200.4 microns, 205 microns, 210 microns, 214.7 microns, 215.9 microns, 220 microns, 221 microns, 225 microns, or 230 microns, which are not limited in the embodiments of the present application.

[0094] It can also be understood that the enameled wire has excellent conductivity and insulation performance, which can improve the energy transmission efficiency between the coil and the external device. For example, the enameled wire can be an acetal enameled wire, a polyester enameled wire, a polyurethane enameled wire, a polyester-imine enameled wire, or a polyimide enameled wire, etc., which are not limited in the embodiments of the present application.

[0095] In some embodiments, the display screen 22 includes a display surface and a back surface away from the display surface. The antenna is located on the side of the back surface of the display screen 22 to receive signals from the outside and control the replacement of patterns or characters output by the display screen 22. For example, taking a mobile phone as an external device, the user can hold the mobile phone close to the back surface of the accessory 2 in the embodiments of the present application, so that the mobile phone and the antenna are closer, and then the near field communication module of the mobile phone and the antenna are inducted to complete corresponding signal transmission, so that the patterns on the display screen 22 are changed, thereby meeting the different personalized needs of the user. If it is necessary to charge the accessory 2, a charging device can also be held close to the back surface of the accessory 2 to improve the charging efficiency.

[0096] In some embodiments, the antenna is installed in the connecting piece 21. That is, the connecting piece 21 is arranged as a shell, and the antenna is installed inside the shell to protect the antenna, reduce the probability of damage to the antenna, and thus improve the service life of the accessory 2. The connecting piece 21 can be arranged in the form of an upper shell and a lower shell clamped together, which is convenient for the installation of the antenna.
