Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0033] The embodiment of the present application provides a dust-proof structure for a display interface, which solves the problem that dust easily accumulates when the existing interface is exposed to the outside, causing short circuits or poor contact between the interfaces, thereby affecting the normal use of the display.

[0034] refer to Figure 1 and Figure 2 The display interface dustproof structure provided in the embodiment of the present application includes a protective shell 1, an interface block 2, a lifting device 3 and a driving device 4.

[0035] Among them, the protective shell 1 includes an inner cavity 10 with an installation port 101, and the bottom wall of the inner cavity 10 is provided with an opening 102. The protective shell 1 is used to be installed on the back shell 100 of the display setting interface 200, so that the installation port 101 faces the back shell 100, and the interface 200 is exposed from the opening 102; the interface block 2 is arranged in the inner cavity 10; the lifting device 3 is arranged in the inner cavity 10, and the lifting device 3 includes a transmission part and a lifting part that are connected to each other, the lifting part is connected to the interface block 2, and the transmission part is used to drive the lifting part to move along the height direction Z of the display, so that the interface block 2 blocks or does not block the interface 200; the driving device 4 is arranged in the inner cavity 10, and the output end of the driving device 4 is connected to the transmission part, which is used to drive the transmission part to rotate to drive the lifting part to move along the height direction Z of the display.

[0036] refer to Figure 3 , Figure 3 1 is a schematic diagram of the display interface dustproof structure installed on the back shell; the protective shell 1 is installed on the back shell 100 in a manner that the installation port 101 of the protective shell 1 faces the back shell 100, so that the interface block 2, the lifting device 3 and the driving device 4 arranged in the inner cavity 10 of the protective shell 1 will be located in the space between the protective shell 1 and the back shell 100, the opening 102 arranged on the bottom wall of the inner cavity 10 will correspond one-to-one to the interface 200 arranged on the back shell 100, the interface block 2 will be located between the opening 102 and the interface 200, and the lifting device 3 can realize the interface block 2 in the height direction Z of the display. The interface block 2 can be moved so that the interface 200 is covered or exposed from the opening 102. When the interface 200 does not need to be plugged with a connecting wire, the interface block 2 can be moved upward so that the interface block 2 is located between the interface 200 and the opening 102, thereby blocking the interface 200 and preventing dust from entering the interface 200. When the interface 200 needs to be plugged with a connecting wire, the interface block 2 can be moved downward so that the interface block 2 does not cover the interface 200, and the interface 200 is exposed from the opening 102, so that the user can plug the connecting wire into the exposed interface 200. This dustproof structure can not only conveniently cover the interface 200 to achieve the purpose of dustproof, but also the entire dustproof structure is directly connected to the back shell 100 of the display, which will not damage the original structure of the display, and there is no need to disassemble the original structure of the display, so the installation and use are simpler and the use scenarios are more extensive.

[0037] In addition, the lifting part of the lifting device 3 drives the interface block 2 to rise and fall by electric drive, and the moving distance of the interface block 2 can be controlled by controlling the rotation speed and rotation duration of the output end of the driving device 4, so that the interface block 2 can be moved more accurately between the interface 200 and the opening 102 to cover the interface 200, and the interface block 2 can be moved away from between the interface 200 and the opening 102 to make the interface 200 completely exposed from the opening 102 to facilitate the user to plug the connecting line on the interface 200.

[0038] It should be noted that when the interface block 2 is located between the interface 200 and the opening 102, the interface block 2 contacts the bottom wall of the inner cavity 10, and the area of ​​the interface block 2 is larger than the area of ​​the opening 102. In this way, the interface block 2 will completely block the opening 102, effectively preventing dust from entering the inner cavity 10 through the gap between the interface block 2 and the bottom wall, thereby accumulating in the interface 200, causing a short circuit or poor contact between the interfaces 200, and affecting the normal use of the display.

[0039] There may be multiple interfaces 200 provided on the back shell 100, and the multiple interfaces 200 may include multiple types, such as a DC interface, an HDMI interface, a TYPE-C interface, and a DP interface, etc. Different types of interfaces 200 have different shapes and sizes. Accordingly, the shape and size of the openings 102 corresponding to the multiple interfaces 200 may be set to be consistent with the shape and size of the corresponding interface 200, so that it is convenient for users to quickly and accurately identify the type of interface 200 corresponding to the opening 102 according to the shape and size of the opening 102, which is more convenient for use. Of course, the shape and size of the openings 102 corresponding to the multiple interfaces 200 may also be set to be the same, that is, multiple openings 102 of the same shape and size are provided on the bottom wall of the inner cavity 10, and each opening 102 corresponds to an interface 200, so that it is convenient to make the opening 102. It should be noted that the size of the opening 102 should be able to ensure that the interface 200 corresponding to the opening 102 is fully exposed, and will not affect the user's normal plugging of the connection line on the interface 200.

[0040] Furthermore, each opening 102 is correspondingly provided with an interface block 2, and each interface block 2 is configured with an independent driving device 4 and an independent lifting device 3, so that each interface 200 can be individually blocked or exposed, and only the interface 200 that needs to be plugged in is exposed, and other interfaces 200 that do not need to be plugged in are blocked. Compared with the solution in which all interfaces 200 are blocked or exposed at the same time, multiple interfaces 200 of the present application can be individually blocked or exposed, which greatly improves the dustproof effect.

[0041] In some embodiments, reference Figure 2The transmission part includes a screw rod 31 extending along the height direction Z of the display; the lifting part includes a screw rod nut 32, the screw rod nut 32 is threadedly connected to the screw rod 31, and the interface stopper 2 is connected to the screw rod nut 32.

[0042] Specifically, when the screw rod 31 rotates, the screw nut 32 threadedly connected to the screw rod 31 will move in the axial direction of the screw rod 31, that is, in the height direction Z of the display. Since the interface block 2 is connected to the screw nut 32, the interface block 2 will move simultaneously with the screw nut 32 to achieve lifting and lowering in the height direction Z of the display. The screw rod 31 converts the rotational motion into linear motion to achieve the lifting and lowering of the interface block 2. The structure is simple, and the space occupied when installed in the inner cavity 10 is also small, and the volume of the dustproof structure will not be increased additionally.

[0043] In some embodiments, reference Figure 2 The driving device 4 includes a motor 41 and a coupling. The driving shaft of the motor 41 is coaxially arranged with the screw rod 31. The coupling is respectively connected to the driving shaft of the motor 41 and one end of the screw rod 31.

[0044] It should be noted that the drive device 4 is arranged on the side of the screw rod 31 away from the opening 102, and the drive shaft of the motor 41 and the end of the screw rod 31 away from the opening 102 are connected through a coupling, so that the rotation of the drive shaft of the motor 41 can drive the screw rod 31 to rotate, so that the screw nut 32 moves in the height direction Z of the display, so as to drive the interface block 2 to rise and fall in the height direction Z of the display. The overall structure of the drive device 4 is simple, and the screw rod 31 is directly driven to rotate in the height direction Z of the display, which not only can ensure that the driving force for driving the screw rod 31 to rotate will not be weakened, but also can ensure that the installation of the drive device 4 in the inner cavity 10 will not increase the overall width of the protective shell 1, and will not affect the spacing when multiple drive devices 4 are installed.

[0045] The motor 41 is a stepper motor or a servo motor, and the motor 41 can be precisely controlled by the stepper motor or the servo motor, thereby improving the operating accuracy of the drive device 4 .

[0046] In some embodiments, reference Figure 1 and Figure 2 The display interface dustproof structure also includes a sensing device 5 and a control device 6. The sensing device 5 is arranged in the inner cavity 10, and is used to sense whether there is an interface connection line close to the interface 200; the control device 6 is electrically connected to the sensing device 5 and the driving device 4, and is used to receive the sensing signal sent by the sensing device 5 to control the driving device 4 to drive the transmission part to rotate so as to drive the lifting part to move along the height direction Z of the display.

[0047] It should be noted that the control device 6 is linked with each interface 200 of the display to identify whether a connecting wire is plugged into the interface 200. When the sensing device 5 senses that a connecting wire is close to the interface 200 and the interface block 2 is moved to expose the interface 200, the control device 6 recognizes that no connecting wire has been inserted into the interface 200 for a long time, and will control the drive device 4 to drive the interface block 2 to move again to cover the interface 200; when the user unplugs the connecting wire plugged into the interface 200, in addition to the sensing device 5 being able to sense the signal that the connecting wire is away from the interface 200, the control device 6 can also recognize that there is no connecting wire plugged into the interface 200. At this time, the control device 6 will control the drive device 4 to drive the interface block 2 to move between the interface 200 and the opening 102 to cover the interface 200; in this way, when there is no connecting wire plugged into the interface 200, the interface block 2 can be moved between the interface 200 and the opening 102 in time to cover the interface 200, effectively preventing dust from entering the interface 200 and achieving a good dustproof effect.

[0048] In addition, when the connecting wire is plugged into the interface 200, the control device 6 recognizes that there is always a connecting wire on the interface 200 and will not control the operation of the drive device 4, ensuring that the interface block 2 is always in the open state, that is, the interface 200 always remains exposed from the opening 102, which will not affect the normal plugging of the connecting wire and use of the interface 200.

[0049] Specifically, when the user holds the connecting wire close to the interface 200, the sensing device 5 corresponding to the interface 200 will send the sensed signal (i.e., the connecting wire is close to the interface 200) to the control device 6, so that the control device 6 will control the driving device 4 to drive the transmission part to rotate to drive the lifting part to move along the height direction Z of the display, so that the interface stopper 2 connected to the lifting part moves in the height direction Z of the display, thereby leaving the position between the interface 200 and the opening 102, so that the interface 200 is exposed from the opening 102, so that the user can easily and quickly plug the connecting wire into the interface 200; when the user holds the interface 2 00 is unplugged, the sensing device 5 corresponding to the interface 200 will send the sensed signal (i.e., a connecting line is away from the interface 200) to the control device 6, and the control device 6 will also identify whether the interface 200 is not plugged with a connecting line. If not, the control device 6 will control the driving device 4 to drive the transmission part to rotate to drive the lifting part to move along the height direction Z of the display, so that the interface block 2 connected to the lifting part moves in the height direction Z of the display, thereby moving to the position between the interface 200 and the opening 102, so that the interface 200 is blocked to prevent dust from entering the interface 200.

[0050] Through the above settings, when the user brings the connecting line close to the interface 200, the interface block 2 blocking the interface 200 will be automatically moved away to expose the interface 200. When the user unplugs the connecting line from the interface 200, the interface block 2 corresponding to the interface 200 will automatically move to a position between the interface 200 and the opening 102 to completely block the interface 200 and prevent dust from entering the interface 200. By automatically moving the interface block 2, the dustproof effect of the dustproof structure is greatly improved, which makes it more convenient for users to use and enhances the user experience.

[0051] In some embodiments, reference Figure 1 The sensing device 5 includes a sensing mark 103, and the sensing mark 103 is disposed on a surface of the protective shell 1 away from the back shell 100. When the user brings the connecting wire close to the interface 200, the sensing device 5 will accurately and quickly sense the signal of the connecting wire close to the interface 200 through the sensing mark 103, and transmit the signal to the control device 6 to control the driving device 4 to drive the interface block 2 to move, so that the interface 200 is exposed.

[0052] It should be noted that the above-mentioned sensing device 5 can be a photoelectric sensor, and the sensing mark 103 can be a through hole set on the surface of the side of the protective shell 1 away from the back shell 100. In this way, when the user brings the connecting line close to the interface 200, the sensing device 5 set in the inner cavity 10 will sense the signal of the connecting line approaching the interface 200 from the through hole, ensuring that the interface block 2 can automatically move when the user plugs the connecting line into the interface 200 to expose the interface 200.

[0053] The number of sensing devices 5 is consistent with the number of interfaces 200, which is also consistent with the number of openings 102. A sensing device 5 is provided on the bottom wall of the inner cavity 10 at a position above each opening 102. At the same time, each sensing device 5 is provided with a through hole as a sensing mark 103 at a position provided on the bottom wall of the inner cavity 10. In this way, each interface 200 corresponds to an independent sensing device 5 to sense whether there is a connecting wire approaching the interface 200, so as to accurately expose the interface 200 to which the user needs to plug the connecting wire, effectively avoiding the situation where the interface 200 that is not plugged in the connecting wire is accidentally exposed and dust enters the interface 200.

[0054] In some embodiments, reference Figure 1 The display interface dustproof structure also includes a mobile power supply 7 and a switch device 8. The mobile power supply 7 is arranged in the inner cavity 10. The mobile power supply 7 is electrically connected to the control device 6 to provide power for the display interface dustproof structure; the switch device 8 is embedded in the inner cavity 10 from the side surface of the protective shell 1 away from the back shell 100, and the switch device 8 is electrically connected to the mobile power supply 7.

[0055] Through the above arrangement, the mobile power supply 7 can independently power the display interface dustproof structure of the present application, so there is no need to change the original circuit inside the display, making the use of the display interface dustproof structure of the present application more convenient, and in addition to being installed on the back shell 100 of the display to protect the interface 200 from dust, it can also be installed on the outer surface of other devices to protect the interface 200 from dust, and the application range is wider; when the interface 200 of the display is not plugged in for a long time, the mobile power supply 7 can be turned off by turning off the switch device 8, thereby saving electricity and extending the service life of the display interface dustproof structure.

[0056] It should be noted that the use of a mobile power supply 7 to supply power to the dustproof structure alone allows the mobile power supply 7 to be removed and charged for use after the dustproof structure has been used for a period of time and the power of the mobile power supply 7 is exhausted, which greatly improves the use efficiency of the mobile power supply 7 and further improves the service life of the dustproof structure. Specifically, a power supply compartment can be provided on the bottom wall of the inner cavity 10, and an installation port 101 that passes through the power supply compartment can be provided on the bottom wall of the inner cavity 10. The user can install or remove the mobile power supply 7 from the installation port 101, and a corresponding cover plate is provided on the installation port 101, so that the mobile power supply 7 can be replaced without removing the dustproof structure from the back shell 100, which greatly improves the convenience of the user in replacing the mobile power supply 7.

[0057] Specifically, the dustproof principle of the display interface dustproof structure of the present application is: the user manually turns on the switch device 8, the mobile power supply 7 supplies power to the dustproof structure, and the dustproof structure enters the standby state. When the user holds the connecting line close to a certain interface 200, the sensing device 5 corresponding to the interface 200 will sense the signal of the connecting line approaching the interface 200 through the sensing mark 103 and transmit it to the control device 6. The control device 6 will control the driving device 4 to drive the interface block 2 to move according to the pre-set stroke, so that the interface 200 is completely exposed from the opening 102. You can refer to Figure 5 , Figure 5 , which is a schematic diagram showing two interfaces 200 exposed from the opening 102; when the user unplugs the connecting wire plugged into the interface 200, the sensing device 5 will sense the signal that the connecting wire is away from the interface 200 and send it to the control device 6. At the same time, the control device 6 will also recognize that the interface 200 is not plugged into the connecting wire. At this time, the control device 6 will control the driving device 4 to drive the interface block 2 to move according to the preset stroke, so that the interface 200 is completely covered to achieve a good dustproof effect. You can refer to Figure 4 , Figure 4 The diagram shown in FIG. 2 is a schematic diagram showing that the interface 200 is completely blocked by the interface block 2 .

[0058] In some embodiments, reference Figure 2The display interface dust-proof structure also includes a guide device 9, which is arranged on the bottom wall of the inner cavity 10; the guide device 9 includes two guide blocks 91 symmetrically arranged with the screw rod 31 as the center axis, and a guide groove 911 is provided on the side of the guide block 91 facing the screw rod 31, and the interface stopper 2 is respectively inserted into the guide groove 911 on both sides of the radial direction X of the screw rod 31 to move along the guide groove 911.

[0059] It should be noted that the setting of the guide device 9 enables the interface block 2 to move along the guide groove 911, so that the lifting and lowering of the interface block 2 will be more stable and will not shake; when the guide block 91 is set, one end of the guide block 91 should protrude from the opening 102 in the axial direction of the screw rod 31, and the other end of the guide block 91 should protrude from the motor 41 in the axial direction of the screw rod 31, so as to ensure that the entire moving stroke of the interface block 2 moves along the guide groove 911, ensuring the stable movement of the interface block 2.

[0060] In some embodiments, reference Figure 2 The interface block 2 is provided with protruding inserts 21 on both sides of the surface along the radial direction X of the screw rod 31; the protruding inserts 21 are in contact with the bottom wall of the guide groove 911, and the interface block 2 is in contact with the side surface of the guide block 91 facing the screw rod 31 on both sides of the surface along the radial direction X of the screw rod 31. In this way, the interface block 2 can be further prevented from shaking when moving along the guide groove 911, and it is more stable.

[0061] In some embodiments, the thickness of the protruding insert 21 is the same as the dimension of the guide groove 911 in the thickness direction of the protruding insert 21. In this way, after the protruding insert 21 is inserted into the guide groove 911, it will be in close contact with the groove side wall of the guide groove 911, so that when the interface block 2 moves between the interface 200 and the opening 102, the passage for dust to enter the interface 200, that is, the space between the interface block 2 and the guide groove 911 is sealed, and the dustproof effect is better.

[0062] In some embodiments, reference Figure 2 The protective shell 1 is provided with a bolt hole 104 on one side surface close to the back shell 100, and the bolt hole 104 is a blind hole, and the protective shell 1 is connected to the back shell 100 by bolts.
