[0043] See also Figures 1 to 14 As shown, according to an embodiment of the present application, an interface protection device is provided, which is at least used to connect a predetermined device 30. The predetermined device 30 includes but is not limited to a display of a medical device, etc. The predetermined device 30 is provided with an interface 31. The interface protection device in this embodiment is used to protect the interface 31. Specifically, the interface protection device includes a main body 10 and a locking component 20.

[0044] The main body 10 is provided with a flexible connection portion 11, which is at least used to connect the main body 10 and the predetermined device 30, and the main body 10 has a first position covering the interface 31 and a second position away from and avoiding the interface 31. The locking component 20 is provided between the main body 10 and the predetermined device 30 to at least lock the main body 10 in the second position.

[0045] In this embodiment, by providing a flexible connection portion 11 at least for connecting the main body 10 and the predetermined device 30 on the main body 10, the flexible connection portion 11 allows a certain range of motion between the main body 10 and the predetermined device 30, so that the interface device can adapt to different angle changes, and the flexible connection portion 11 has good flexibility, which can absorb vibration and deviation of the connection, thereby reducing the risk of wear and breakage of the connection caused by vibration and deviation. In actual use, when the main body 10 is in the first position, the interface 31 can be covered to prevent external dust or liquid from entering the interface 31 and causing damage to the electrical components at the interface 31. When the main body 10 is in the second position, the interface 31 can be exposed on the outer surface of the predetermined device 30, which is convenient for the interface 31 to be connected with an external wiring harness or other components.

[0046] At the same time, this embodiment provides a locking component 20 between the main body 10 and the predetermined device 30, which is at least used to lock the main body 10 in the second position away from and avoiding the interface 31. The locking component 20 can ensure that the main body 10 is stable and does not shake when it is in the second position, and can avoid shaking of the main body 10 caused by external factors such as vibration and impact, thereby avoiding wear and breakage at the connection between the main body 10 and the predetermined device 30. In addition, the locking component 20 can prevent the main body 10 from returning to the position covering the interface 31 due to the flexible nature of the flexible connection part 11, and avoid the main body 10 from obstructing or interfering with the plugging and unplugging action when the interface 31 is connected to the wiring harness or other components.

[0047] Specifically, the locking component 20 of this embodiment includes at least one of a clamping component 21 and a magnetic component 22. That is, the locking component 20 in this embodiment can be a clamping component 21, a magnetic component 22, or a combination of the clamping component 21 and the magnetic component 22, which has a simple structure and low production cost.

[0048] Specifically, the snap assembly 21 includes a snap 211 and a slot 212, one of which is provided on the main body 10, and the other is provided on the first contact surface 32 of the predetermined device 30. That is, when the snap 211 is provided on the main body 10, the slot 212 is provided on the predetermined device 30, and when the snap 211 is provided on the first contact surface 32 of the predetermined device 30, the slot 212 is provided on the main body 10.

[0049] Further, the predetermined device 30 includes a first contact surface 32 and a second contact surface 33 located at the edge of the first contact surface 32, and the interface 31 of the predetermined device 30 is arranged on the first contact surface 32. In some embodiments of the present application, the buckle 211 is arranged on the main body 10, and the first contact surface 32 and the second contact surface 33 are both provided with a card slot 212. In actual use, the buckle 211 cooperates with the card slot 212 on the first contact surface 32, so that the main body 10 is in the first position, and the buckle 211 cooperates with the card slot 212 on the second contact surface 33, so that the main body 10 is in the second position.

[0050] Of course, in other embodiments of the present application, the card slot 212 may be provided on the main body 10, and the buckle 211 may be provided on both the first contact surface 32 and the second contact surface 33. In actual use, the card slot 212 cooperates with the buckle 211 on the first contact surface 32 to place the main body 10 in the first position; the card slot 212 cooperates with the buckle 211 on the second contact surface 33 to place the main body 10 in the second position.

[0051] More specifically, in the first case of the present embodiment, by providing a card slot 212 on both the first contact surface 32 and the second contact surface 33, when the main body 10 is in the first position, the buckle 211 on the main body 10 can cooperate with the card slot 212 on the second contact surface 33 to engage with the main body 10, so that the main body 10 is fixed in the first position, that is, the interface protection device just covers the interface 31 of the predetermined device 30, so that the interface 31 of the predetermined device 30 can be covered when it is not needed, thereby effectively preventing dust, moisture or other contaminants from entering the interface 31, thereby extending the service life of the interface 31. When the interface 31 of the predetermined device 30 needs to be used, the main body 10 is moved to the second position and the buckle 211 on the main body 10 is engaged with the slot 212 on the second contact surface 33 of the predetermined device 30 to fix the main body 10 in the second position away from and away from the interface 31, thereby avoiding interference with the use of the interface 31 when the main body 10 is in the open state, and also avoiding the main body 10 from shaking easily when in the open state, which may cause wear and further breakage at the connection between the main body 10 and the predetermined device 30, thereby improving the service life of the interface protection device.

[0052] In the second case of this embodiment, by setting the card slot 212 on the main body 10, the buckle 211 is set on the first contact surface 32 and the second contact surface 33. When the main body 10 is in the first position, the card slot 212 on the main body 10 can be engaged with the buckle 211 on the first contact surface 32, so that the main body 10 is fixed in the first position. Similarly, when the main body 10 is in the second position, the card slot 212 on the main body 10 can be engaged with the buckle 211 on the second contact surface 33, so that the main body 10 is fixed in the second position away from and away from the interface 31. This embodiment fixes the main body 10 in different positions when it is in different states by means of a buckle connection. The connection is tight and firm, and it is not easy to loosen, which ensures the stability and safety of the interface. The buckle connection does not require other locking accessories, saving costs.

[0053] Further, the magnetic attraction component 22 includes a magnetic attraction main component 221 and a magnetic attraction auxiliary component 222, one of which is disposed on the main body 10, and the other is disposed on the predetermined device 30. That is, when the magnetic attraction main component 221 is disposed on the main body 10, the magnetic attraction auxiliary component 222 is disposed on the first contact surface 32 of the predetermined device 30, and when the magnetic attraction auxiliary component 222 is disposed on the main body 10, the magnetic attraction main component 221 is disposed on the first contact surface 32 of the predetermined device 30.

[0054] In some embodiments of the present application, the magnetic main component 221 is disposed on the main body 10, and the magnetic auxiliary component 222 is disposed on both the first contact surface 32 and the second contact surface 33. In actual use, the magnetic main component 221 cooperates with the magnetic auxiliary component 222 on the first contact surface 32 to place the main body 10 in the first position; the magnetic main component 221 cooperates with the magnetic auxiliary component 222 on the second contact surface 33 to place the main body 10 in the second position.

[0055] In other embodiments of the present application, the magnetic auxiliary component 222 is provided on the main body 10, and the magnetic main component 221 is provided on both the first contact surface 32 and the second contact surface 33. In actual use, the magnetic auxiliary component 222 cooperates with the magnetic main component 221 on the first contact surface 32 to place the main body 10 in the first position; the magnetic auxiliary component 222 cooperates with the magnetic main component 221 on the second contact surface 33 to place the main body 10 in the second position.

[0056] More specifically, in the first case of the present embodiment, by providing a magnetic auxiliary component 222 on both the first contact surface 32 and the second contact surface 33, when the main body 10 is in the first position, the magnetic main component 221 on the main body 10 can cooperate with the magnetic auxiliary component 222 on the second contact surface 33 for magnetic connection, so that the main body 10 is fixed in the first position, that is, the position where the interface protection device just covers the interface 31 of the predetermined device 30, so that the interface 31 of the predetermined device 30 can be covered when it is not needed, thereby effectively preventing dust, moisture or other contaminants from entering the interface 31, thereby extending the service life of the interface 31. When the interface 31 of the predetermined device 30 needs to be used, the main body 10 is moved to the second position and the magnetic main component 221 on the main body 10 is magnetically connected with the magnetic auxiliary component 222 on the second contact surface 33 of the predetermined device 30, so that the main body 10 is fixed in the second position away from and away from the interface 31, thereby avoiding interference with the use of the interface 31 when the main body 10 is in the open state, and also avoiding the main body 10 from shaking easily when in the open state, which may cause wear and further breakage at the connection between the main body 10 and the predetermined device 30, thereby improving the service life of the interface protection device.

[0057] In the second case of the present embodiment, the magnetic auxiliary component 222 is arranged on the main body 10, and the magnetic main component 221 is arranged on the first contact surface 32 and the second contact surface 33. When the main body 10 is in the first position, the magnetic auxiliary component 222 on the main body 10 can cooperate with the magnetic main component 221 on the first contact surface 32 to form a magnetic connection, so that the main body 10 is fixed in the first position. Similarly, when the main body 10 is in the second position, the magnetic main component 221 on the main body 10 can cooperate with the magnetic auxiliary component 222 on the second contact surface 33 to form a magnetic connection, so that the main body 10 is fixed in the second position away from and away from the interface 31. The present embodiment fixes the main body 10 in different positions when it is in different states by means of a magnetic connection. The magnetic connection has the functions of automatic adsorption and self-locking interaction, and can achieve seamless docking without additional force, providing stable and reliable contact force and connection, and the magnetic connection also has a long service life, ensuring the durability of the interface.

[0058] Furthermore, the magnetic main part 221 includes a magnet, and the magnetic auxiliary part 222 includes iron or a magnet. By adsorbing the magnet to the iron or the magnet to the magnet, the main body 10 can be quickly locked in the first position or the second position, which has a simple structure and is easy to operate. Of course, in other embodiments of the present application, the second magnetic auxiliary part 222 can also include other ferromagnetic metals.

[0059] Specifically, a connecting hole 34 for connecting the flexible connecting part 11 to the predetermined device 30 is provided on the predetermined device 30.

The flexible connecting part 11 is passed through the connecting hole 34 and is limited in the connecting hole 34 by the limiting boss 111.

[0060] In this embodiment, the flexible connection part 11 is inserted into the connection hole 34 and is limited by a limiting boss 111 protruding from the outside of the flexible connection part, so that a stable connection relationship can be established between the main body 10 and the predetermined device 30, effectively preventing the main body 10 from shaking or falling off when it does not need to be moved. The strip-shaped design of the flexible connection part 11 allows it to be easily inserted into the connection hole 34, and the limiting boss 111 ensures the stability after installation. The limiting boss 111 can also effectively prevent the main body 10 from accidentally moving due to external factors such as vibration and collision when it does not need to be moved, further ensuring the stability and safety of the interface protection device.

[0061] refer to Fig.11 and Fig.13 As shown, a protrusion 12 is also provided on the main body 10. When the main body 10 is in the first position, the protrusion 12 is plugged into the interface 31 to form a tight fit. By providing the protrusion 12 on the main body 10, the sealing of the interface 31 is enhanced, and dust, moisture or other contaminants can be effectively prevented from entering the interior of the predetermined device 30 through the interface, thereby extending the service life of the interface 31 of the predetermined device 30.

[0062] On the other hand, the present application also discloses an electronic device, which includes the above-mentioned interface protection device. Therefore, the electronic device includes all the technical effects of the above-mentioned interface protection device, which will not be repeated here because the technical effects of the interface protection device have been described in detail above.

[0064] (1) The interface protection device of the present application can be fixed in a second position away from and away from the interface when the interface is not in use, thereby preventing the main body of the interface protection device from shaking and affecting the plugging and unplugging of the interface, and preventing the connection with the predetermined device from being worn and broken;

[0065] (2) The interface protection device of the present application can fix the main body of the interface protection device in corresponding positions in different states by means of a snap-on or magnetic connection. The interface of the snap-on component or the magnetic component is simple and can achieve efficient fixation.

[0066] (3) The protrusions provided on the interface protection device of the present application can fit tightly with the interface of the predetermined device, preventing contaminants from entering the interface and extending the service life of the interface.

[0067] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0068] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
