As Figure 1 andFigure 2 As shown, the electronic device 10 includes a body 12, a detachable element 14, a host board 16 and a deformable closure 18. In one embodiment, the electronic device 10 is, for example, a card reader, the body 12 of the electronic device 10 includes a first surface 121 and a second surface 122 opposite to each other, and a pressure channel 20 is formed on the body 12, the pressure channel 20 includes a first end 201 and a second end 202, and the pressure channel 20 penetrates the first surface 121 or / and the second surface 122.

[0030] As described above, the detachable element 14 is disposed on the body 12 and covers the first end 201 of the pressure channel 20. In one embodiment, the detachable element 14 is, for example, a touch panel, and is disposed on the first surface 121 of the body 12 to cover the first end 201 of the pressure channel 20. In addition, the deformable closure 18 seals the second end 202 of the pressure channel 20 (indicated in Figure 1 ), and the deformable closure 18 is, for example, a metal sheet, and includes a central region 181 and a peripheral region 182.

[0031] In addition, the host board 16 is disposed on the body 12. In one embodiment, the host board 16 is disposed on the opposite side of the body 12 away from the detachable element 32 (for example, the touch panel) and is adjacent to the second end 202 sealed by the deformable closure 18, and the host board 16 is provided with a sensing element 22, and the position of the sensing element 22 corresponds to the position of the pressure channel 20. In one embodiment, the sensing element 22 is, for example, a switching element or a detection element, wherein the switching element can be a metal element. In addition, a safety loop (not shown in the figure) is further disposed on the host board 16, and the safety loop is electrically connected to the sensing element 22.

[0032] Figure 3A is a perspective sectional view of an electronic device according to a first embodiment of the present application, wherein the pressure channel is in a negative pressure state, Figure 3B is another perspective sectional view of the electronic device according to the first embodiment of the present application, wherein the pressure channel is not in a negative pressure state. As shown in Figure 3A and Figure 3B In one embodiment, the peripheral region 182 of the deformable closure 18 is disposed on the peripheral wall of the pressure channel 20, and the central region 181 corresponds to the pressure channel 20. As shown in Figure 3A , when the pressure channel 20 is in a negative pressure state, the deformable closure 18 presents a first deformation state, and in one embodiment, the first deformation state of the deformable closure 18 is that the central region 181 is concave towards the second end 202 (indicated in Figure 1 ), and the central region 181 is away from the sensing element 22 and does not contact the sensing element 22. As shown in Figure 3BAs shown, the deformable closure 18 assumes a second deformed state in which the central region 181 of the deformable closure 18 is not recessed but returns to a flat state and contacts the sensing element 22. In one embodiment, as the deformable closure 18 contacts the sensing element 22, a security circuit is in an on state.

[0033] In the above embodiment, when the electronic device 10 is assembled, the pressure channel 20 is continuously in a negative pressure state by the first end 201 of the pressure channel 20 being covered by the detachable element 14 (e.g. a touch panel) and the second end 202 of the pressure channel 20 being closed by the deformable closure 18, and the deformable closure 18 is always not in contact with the sensing element 22. Once someone intends to disassemble the electronic device 10, for example, by removing the detachable element 14 (e.g. a touch panel), the negative pressure state of the pressure channel 20 is destroyed, causing the deformable closure 18 to return to a flat state and contact the sensing element 22, so that the security circuit on the main board 16 is turned on to immediately destroy the stored information.

[0034] Figure 4 is a perspective exploded view of an electronic device according to a second embodiment of the present application, Figure 5 is a perspective view of an electronic device according to a second embodiment of the present application. As shown in Figure 4 and Figure 5 The electronic device 10A includes a body 12A, a main board 16 and a deformable closure 18. The body 12A includes opposite first and second surfaces 121 and 122. In one embodiment, the body 12A includes a front housing 123 and a rear housing 124, the front housing 123 is adapted to be covered by the rear housing 124, wherein the first surface 121 is located on the front housing 123, for example, and the second surface 122 is located on the rear housing 124, for example, and the main board 16 is disposed between the front housing 123 and the rear housing 124.

[0035] A pressure channel 20A is formed on the body 12A, the pressure channel 20A includes a first end 201 and a second end 202. In one embodiment, as shown in Figure 4 The pressure channel 20A is formed on the rear housing 124, the first end 201 of the pressure channel 20A is adjacent to the second surface 122 but does not penetrate the second surface 122 as a closed end, and the second end 202 of the pressure channel 20A is adjacent to the main board 16. Figure 4 As shown, the main board 16 is provided with a sensing element 22 and a support 24, for example, in the form of a ring, surrounding the periphery of the sensing element 22, and the position of the sensing element 22 corresponds to the position of the pressure channel 20A.

[0036] As described above, Figure 6A is a perspective cross-sectional view of an electronic device according to a second embodiment of the present application, in which the pressure channel is in a negative pressure state; Figure 6Bis another perspective cross-sectional view of a second embodiment of the electronic device of the present application, in which the pressure channel is not in the negative pressure state. As shown in Figure 6A and Figure 6B The deformable closure 18 is secured between the support 24 and the pressure channel 20A, and the deformable closure 18 closes the second end 202 (indicated in Figure 4 ) of the pressure channel 20A. The deformable closure 18 is, for example, a metal sheet. The deformable closure 18 includes a central region 181 and a peripheral region 182. In one embodiment, the peripheral region 182 is disposed on the support 24 so as to be sandwiched by the periphery of the pressure channel 20A and the support. The central region 181 corresponds to the pressure channel 20A. When the pressure channel 20A is in the negative pressure state, the deformable closure 18 assumes a first deformed state, in which, in one embodiment, the central region 181 is concave toward the second end 202, and the central region 181 is distanced from the sensing element 22 without contacting the sensing element 22. When the rear housing 124 is separated from the front housing 123, the pressure channel 20A is not in the negative pressure state, and the deformable closure 18 assumes a second deformed state, in which the central region 181 of the deformable closure 18 is not concave but returns to a flat state and contacts the sensing element 22. In one embodiment, when the deformable closure 18 contacts the sensing element 22, a safety circuit on the main board 16 is in a conductive state. Figure 6A Figure 6B

[0037] In the above embodiment, the electronic device 10A is assembled, and the first end 201 of the pressure channel 20A is a closed end. The second end 202 of the pressure channel 20A is closed by the deformable closure 18, so that the pressure channel 20A is continuously in the negative pressure state, that is, the deformable closure 20A is always distanced from the sensing element 22. Once someone attempts to disassemble the electronic device 10A, for example, to separate the front housing 123 and the rear housing 124, the negative pressure state of the pressure channel 20A is destroyed, causing the deformable closure 18 to return to the flat state and contact the sensing element 22, so that the safety circuit on the main board 16 is conductive, to immediately destroy the stored information.

[0038] According to the above, the present application provides a pressure channel on the body of an electronic device, and in the normal use state of the electronic device, the pressure channel is in a negative pressure state. One end of the pressure channel is closed by a deformable closure. The destruction of the negative pressure state causes the deformable closure to return from a first deformed state to a second deformed state, and the deformable closure contacts a sensing element, so that a safety protection mechanism of a safety circuit electrically connected to the sensing element is activated. Therefore, the electronic device has a highly sensitive safety protection mechanism for accessing data.
