[0026] The application will be described in further detail below with reference to the drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only intended to explain the present application and are not intended to limit the present application, and, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] As Figures 1-2 shown, the present application provides an optional embodiment of a shielding device 1 of an external port of an electronic device, which comprises:

[0028] a base 10 arranged beside the external port 3, wherein the base 10 is provided with a guide part 101;

[0029] a cover plate 12 assembled on the base 10 and capable of sliding along the guide part 101 between a shielding position A shielding the external port 3 and an open position B exposing the external port 3; and

[0030] a driving assembly 14 for driving the cover plate 12 to slide along the guide part 101, wherein the driving assembly 14 comprises:

[0031] a first driving member 141 and a second driving member 143 respectively for applying force to the cover plate 12 from opposite first and second directions and keeping the cover plate 12 in the shielding position A in a normal state, wherein the first driving member 141 is made of shape memory alloy; and

[0032] a first shape adjuster 145 for responding to a first external control instruction to cause the first driving member 141 to change shape and apply force to the cover plate 12 to move the cover plate 12 from the shielding position A to the open position B.

[0033] The utility model embodiment adds the shielding device 1 at the external port 3 of the electronic equipment, under the normal state, the cover plate 12 is at the shielding position A, and the external port 3 will not be exposed. When needing to use the external port 3 to connect the external equipment, the user sends the start instruction (part of the first external control instruction) to the first shape adjuster 145, and the first shape adjuster 145 works to make the first driving part 141 change the shape, so that the cover plate 12 is driven by the first driving part 141 to overcome the force of the second driving part 143 on the cover plate 12 and moves to the open position, so that the external port 3 is exposed to facilitate the connection of the external equipment. When the use of the external port is finished, the user can give the first shape adjuster 145 a stop instruction (another part of the first external control instruction) to make the first shape adjuster 145 stop working, so as to make the first driving part 141 restore to the shape under the normal state, and the force applied by the second driving part 143 on the cover plate 12 promotes the cover plate 12 to return to the initial shielding position A, so that the automatic closing and opening of the external port 3 are realized, and the controllability is good.

[0034] In the specific implementation, it can be understood that the normal state refers to the normal temperature state (for temperature-induced shape memory alloy) or the state without external pressure (for stress-induced shape memory alloy) that does not cause the shape memory alloy to change the shape.

[0035] In an optional embodiment of the utility model, the second driving member 143 is also made of shape memory alloy, and the driving assembly 14 further comprises a second shape adjuster for responding to a second external control instruction to cause the second driving member 143 to change shape and apply force to the cover plate 12 to make the cover plate 12 reset to the position of covering the external port 3. In this embodiment, the second driving member 143 is also made of shape memory alloy, and cooperates with the corresponding second shape adjuster, so that the cover plate 12 can be moved back and forth between the shielding position and the open position by the force applied by the first driving member 141 and the second driving member 143. In specific implementation, according to the different setting positions and force applying modes of the first driving member 141 and the second driving member 143, the shape change trends of the first driving member 141 and the second driving member 143 can be the same or opposite, for example: when the first driving member 141 changes from the shape in the normal state to the shape in the abnormal state, its length becomes longer, and no force is applied to the cover plate 12, while the second driving member 143 changes from the shape in the normal state to the shape in the abnormal state, its length also becomes longer, and a pushing force is applied to the cover plate 12 to move the cover plate 12 to the open position; when the first driving member 141 changes from the shape in the abnormal state to the shape in the normal state, its length becomes shorter, and a pulling force is applied to the cover plate 12, at this time, the second driving member 143 changes from the shape in the abnormal state to the shape in the normal state, its length also becomes shorter, and no pushing force is applied to the cover plate 12, at this time, the cover plate 12 resets to the shielding position under the pulling force of the first driving member 141. If the first driving member 141 and the second driving member 143 are arranged on the outer sides of different ends of the cover plate 12, when the first driving member 141 changes from the shape in the normal state to the shape in the abnormal state, its length becomes shorter, and a pulling force is applied to the cover plate 12, while the second driving member 143 changes from the shape in the normal state to the shape in the abnormal state, its length becomes longer, and no pulling force is applied to the cover plate 12, the cover plate 12 moves to the open position under the pulling force of the first driving member 141; when the first driving member 141 changes from the shape in the abnormal state to the shape in the normal state, its length becomes longer, and no pulling force is applied to the cover plate 12, at this time, the second driving member 143 changes from the shape in the abnormal state to the shape in the normal state, its length becomes shorter, and a pulling force is applied to the cover plate 12 to make the cover plate 12 reset to the shielding position A.

[0036] In an optional embodiment of the utility model, as Figure 1 and Figure 2As shown, the second driving member 143 is a spring or an elastic rubber strip. In this embodiment, the second driving member 143 can also be a spring or an elastic rubber strip. When it is needed to open the external port 3, the first shape adjuster 145 is powered to the first driving member 141 for a short time, so that the cover plate 12 is displaced from the shielding position A to the open position B; and when the external port 3 is used, the first shape adjuster 145 stops powering the first driving member 141, and the spring or the elastic rubber strip automatically releases the elastic potential energy to drive the cover plate 12 to return to the shielding position A to close the external port 3, without the need of power supply; the whole process only needs to power the first driving member 141 for a short time when the external port 3 is opened, and the power consumption of the electronic device is very small, which is especially suitable for various mobile small electronic devices (such as mobile phones, cameras, and vehicle recorders).

[0037] In specific implementation, according to different installation positions, different shapes of springs or elastic rubber strips can be selected as the second driving member 143, so as to apply elastic pulling force or elastic pushing force to the cover plate 12 through stretching or compression.

[0038] In an optional embodiment of the utility model, the first driving member 141 is a wire made of temperature-induced shape memory alloy, and the first shape adjuster 145 is a power supply for powering the first driving member 141 to change the temperature state of the first driving member 141; or,

[0039] The first driving member 141 is a wire made of stress-induced shape memory alloy, and the first shape adjuster 145 is a force applying member for applying force to the first driving member 141 to change the internal stress state of the first driving member 141.

[0040] In this embodiment, the shape memory alloy can be divided into temperature-induced shape memory alloy and stress-induced shape memory alloy. For the temperature-induced shape memory alloy, the first shape adjuster 145 adopts a power supply to power it, which changes the temperature state and deforms after being powered; for the stress-induced shape memory alloy, the first shape adjuster 145 applies force to it, so that the internal stress state changes and deforms.

[0041] In an optional embodiment of the utility model, the first driving member 141 is a wire which has a standard length and is relatively relaxed at normal temperature and does not exert a pulling force on the cover plate 12 but the length is relatively shortened to exert a pulling force on the cover plate 12 when the temperature is higher than the balance temperature of the shape memory alloy; the second driving member 143 is a wire which has a standard length at normal temperature and exerts a pulling force on the cover plate 12 but the length is relatively lengthened to relax and does not exert a pulling force on the cover plate 12 when the temperature is higher than the balance temperature of the shape memory alloy, the first shape adjuster 145 and the second shape adjuster are power supplies for respectively energizing the first driving member 141 and the second driving member 143 to change the temperature state of the first driving member 141 and the second driving member 143; the first driving member 141 and the second driving member 143 are respectively arranged at opposite ends of the cover plate 12. In the embodiment, when the first driving member 141 and the second driving member 143 both adopt shape memory alloys, by reasonably selecting materials, one of them adopts a wire which has a standard length and is relatively relaxed at normal temperature and does not exert a pulling force on the cover plate 12 but the length is relatively shortened when the temperature is higher than the balance temperature of the shape memory alloy, and the other adopts a wire which has a standard length at normal temperature and exerts a pulling force on the cover plate 12 but the length is relatively lengthened to relax and does not exert a pulling force on the cover plate 12 when the temperature is higher than the balance temperature of the shape memory alloy, so that after energization by the power supply, the two have driving forces in opposite directions. The above is described by taking the example that the first driving member 141 and the second driving member 143 respectively exert pulling forces on the cover plate 12, and it can be understood that in other embodiments, the first driving member 141 and the second driving member 143 can also exert pushing forces on the cover plate 12.

In the embodiment, the two guide rails of the base 10 as the guide portion 101 can simply and conveniently guide the directional sliding of the cover plate 12, and ensure the stable movement of the cover plate 12; and the limiting members 103 at the ends of the guide rails can block the cover plate 12 and avoid the position deviation of the cover plate 12.

[0044] Specifically, the limiting members 103 at the same end of the two guide rails can also be connected into a beam to make the base 10 as a whole in the shape of a rectangular frame, so that the integrity of the base 10 structure is better, the relative position accuracy between components can be improved, and assembly and use are facilitated.

In this embodiment, the third magnetic attraction members 123 and the fourth magnetic attraction members 125 are arranged on the two cover plates 12 to be attracted to each other, so that when the cover plates 12 shield the external port 3, the cover plates 12 can be kept at the shielding position A, avoiding displacement of the cover plates 12 by external force.
