While exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure can be embodied in various forms without being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0042] It should be noted that the technical terms or scientific terms used in the present application should be understood as their common meanings understood by those skilled in the art, unless otherwise specified.

[0043] The protective device of the present application is suitable for scenarios where it is necessary to protect the interface of an electronic device from physical damage and unauthorized access to ensure the information security of the electronic device. For example, it is applied to a notebook computer in a live broadcast environment of a sports event, or a control and command system in a military operation or a national defense facility, etc. Alternatively, it is applied to a control device with strict requirements for information security in industrial production, etc.

[0044] As shown in Figures 1 to 4 The present disclosure provides a protective device, comprising:

[0045] a first housing 1 having a containing space 11 for containing an interface group of an electronic device and an external device connected with the interface group;

[0046] a second housing 2 detachably connected with the first housing 1;

[0047] Wherein, when the first housing 1 and the second housing 2 are connected, the first housing 1 and the second housing 2 can jointly form a protective structure capable of limiting the connection between the interface group and an external device.

[0048] The first shell 1 is used to provide a safe and controlled accommodation space 11. The first shell 1 can include a connecting piece 13 and a protective piece 14. The connecting piece 13 can be used to contact the whole bottom of the electronic device to enhance the protection effect; or the connecting piece 13 can be used to contact part of the bottom of the electronic device to achieve lightweight design, while facilitating the ventilation and heat dissipation of the electronic device. The connecting piece 13 can be partially folded on the side to form a first folding part 131, which is used to contact part of the side of the electronic device. In the case where the first shell 1 and the second shell 2 are connected, the first folding part 131 can limit the electronic device in the protective device. For example, when the electronic device is a notebook computer, the folding part can contact the hinge of the notebook computer, thereby effectively fixing the notebook computer and preventing it from sliding or shifting. Alternatively, the connecting piece 13 can be folded on all sides to form a second folding part, part of the second folding part is used to contact the side of the electronic device, and the other part of the second folding part is spaced from the side of the electronic device to form the protective piece 14. The keyboard of the notebook computer can be placed in the second folding part.

[0049] The connecting piece 13 can be selected as a solid plate to enhance the rigidity and support of the overall structure; or the connecting piece 13 can be selected as a lattice plate to reduce the weight of the first shell 1, facilitate ventilation and heat dissipation, etc. The shape of the cross section of the connecting piece 13 is not further limited, for example, it can be rectangular, polygonal, cross-shaped or irregular, etc.

[0050] The protective piece 14 is used to protect the interface group of the electronic device and the external device. The protective piece 14 can be spaced from the interface group of the electronic device as a whole; or part of the protective piece 14 can be spaced from the interface group of the electronic device, and the other part of the protective piece 14 can be in contact with the interface group. The protective piece 14 can be located at the edge of the connecting piece 13 to make the overall structure more compact. The protective piece 14 can be integrally formed with the connecting piece 13; or the protective piece 14 can be welded with the connecting piece 13. The protective piece 14 can be in a semi-enclosed structure, for example, it can be C-shaped or U-shaped, etc., to form the accommodation space 11 together with the connecting piece 13. The number of protective pieces 14 can be one or more. When the protective piece 14 is more than one, the plurality of protective pieces 14 can cooperate with the connecting piece 13 to form a plurality of accommodation spaces 11.

[0051] The accommodation space 11 not only protects the external device and the interface group from physical damage, but also ensures that the interface group and the external device are in a controlled environment. Among them, the external device is a hardware component required for the normal operation of the electronic device, and the external device exchanges data or supplies power with the electronic device through the interface group, etc., to complete a specific function or task together.

The size of the accommodation space 11 can be specifically designed according to the volume of the external device.

[0053] The second shell 2 cooperates with the first shell 1 to form a complete protection structure, so as to avoid the whole electronic device from being separated from the protection device and ensure the protection effect of the protection device. The second shell 2 can be selected as a solid plate to enhance the rigidity and support force of the overall structure; or the second shell 2 can be selected as a grid plate to reduce the weight of the second shell 2, which is beneficial to ventilation and heat dissipation, etc. The second shell 2 can be detachably connected with the first shell 1 by bolts or clamping, so as to protect or release the protection of the electronic device based on the requirements of the use scene.

[0054] The second shell 2 can be spaced from the operation part of the electronic device to ensure the normal use of the operation part of the electronic device. The operation part of the electronic device is a part of the electronic device that can receive an input or operation instruction, such as a power button, a volume adjustment button, a keyboard, or a touchpad. The second shell 2 can be a half-enclosing structure as a whole, for example, the second shell 2 can be in the shape of U or N, and the bending part of the connecting piece 13 can be opposite to the opening of the second shell 2, so that the first shell 1 and the second shell 2 jointly limit the sliding or displacement of the electronic device when connected. Alternatively, the second shell 2 can have multiple second shells 2, and the multiple second shells 2 can be arranged to form a half-enclosing structure, and the cross section of the second shell 2 can be rectangular, circular, or irregular, etc.

The clamping piece 32 can be integrally formed with the connecting piece 13; or the clamping piece 32 can be connected with the connecting piece 13 by screwing, buckling or bonding, etc. The shape of the clamping piece 32 is adapted to the shape of the external device.

[0063] The clamp, the limiting column 31 and the clamping piece 32 can be selectively arranged or combined.

[0064] As shown in Figure 1 and Figure 3 in some embodiments, further comprising at least one selected from the following combinations:

[0065] The first spacer 4 is arranged between the electronic device and the first shell 1, and the electronic device is spaced apart from and opposite to the first shell 1.

[0066] The second spacer 5 is arranged between the electronic device and the second shell 2, and the electronic device is spaced apart from and opposite to the second shell 2.

[0067] The first spacer 4 is located on the inner side of the protection structure. The first spacer 4 can include a plurality of first sub-spacers 41 and a plurality of second sub-spacers 42. The plurality of first sub-spacers 41 are used to collectively support the electronic device, so that the bottom of the electronic device is spaced apart from the connecting piece 13, and the heat dissipation effect of the electronic device is ensured. The plurality of first sub-spacers 41 can be arranged at intervals, and the first sub-spacers 41 can be integrally formed with the connecting piece 13, or the first sub-spacers 41 can be bonded or bolted to the connecting piece 13, etc. The plurality of second sub-spacers 42 are used to collectively contact the peripheral side of the electronic device, so that the peripheral side of the electronic device is spaced apart from the first shell 1, and the heat dissipation effect of the electronic device is ensured. The plurality of second sub-spacers 42 can be arranged at intervals at the edge of the connecting piece 13, and the second sub-spacers 42 can be connected with the connecting piece 13; or the second sub-spacers 42 can be connected with the protection piece 14.

[0068] The shape of the first spacer 4 can be plate-shaped or columnar. When the first spacer 4 is columnar, the limiting column 31 can form the first spacer 4. The first side of the first spacer 4 away from the connecting piece 13 can be provided with a mounting hole, and the second shell 2 can be connected with the first spacer 4 through the mounting hole, so as to realize the thin design of the first shell 1.

[0069] The second spacer 5 is located on the inner side of the protection structure. The second spacer 5 can have a plurality of second spacers 5, which are used to collectively contact the operating part of the electronic device, so that the operating part of the electronic device is spaced apart from the connecting piece 13, and the heat dissipation effect of the electronic device is ensured. The plurality of second spacers 5 can be arranged at intervals, and the second spacers 5 can be integrally formed with the second shell 2, or the second spacers 5 can be bonded or bolted to the second shell 2, etc.

[0070] As shown in Figure 3 and Figure 4 in some embodiments, the second shell 2 is used to shield the operating part of the electronic device.

[0071] The second shell 2 can be used to shield the entire operating part of the electronic device to enhance the security of the electronic device. In this scenario, the user can input all necessary instructions through the touch screen of the electronic device.

[0072] The second shell 2 can be selected from at least one of the following combinations:

[0073] The second shell 2 has a missing area 21 to expose part of the keys of the operating part. The second shell 2 can have a through hole which can form the missing area 21; or the side of the second shell 2 can be inwardly recessed to form a groove which extends to both surfaces of the second shell 2, and the groove forms the missing area 21. The exposed keys can be frequently used keys, such as the power button or shortcut keys on a notebook computer, to improve the convenience of use while providing security protection for the electronic device.

[0074] In order to facilitate the operation of the staff, the protective device can further include an adapter. The adapter can match the shape and size of the exposed keys. The adapter can be located in the through hole, and the adapter can be connected to the exposed keys by adhesion or magnetic attraction, and part of the adapter protrudes out of the second shell 2; or the adapter can be in the same plane as the second shell 2 to facilitate the key operation of the staff.

[0075] The second shell 2 has a heat dissipation hole 22. The position of the heat dissipation hole 22 can be optimized according to the heat generating area of the electronic device. For example, the heat dissipation hole 22 can be arranged near the heat source of the electronic device (such as the central processing unit, the graphics processing unit, and the position corresponding to the fan or other heat dissipation devices). The heat dissipation hole 22 can be circular, square, strip-shaped or other geometric shapes, and the specific shape can be designed according to the requirements of design aesthetics and manufacturing process.

[0076] In the scenario where the protective device of the present application is applied to a notebook computer, the second shell 2 can be turned over to make the first surface of the second shell 2 away from the first shell 1 contact the bearing surface. The first surface of the second shell 2 away from the first shell 1 is configured with a support 23.

The size and shape of the connector 6 are matched to the display of the electronic device to ensure a secure connection. The connector 6 may include a connecting plate 61 and two sub-connectors 626. The connecting plate 61 is located between the two sub-connectors 626 and is connected to each of the two sub-connectors 626. The two sub-connectors 626 together achieve the connection with the display. To ensure the stability of the connector 6 connection, a slide rail 621 can be configured on the opposing surfaces of the two sub-connectors 626. The display is connected to the two sub-connectors 626 by sliding. The slide rail 621 is used to constrain the movement path of the display during the connection process, ensuring a smooth and reliable connection. The connecting plate 61 may be configured with a third partition 63 to isolate the back of the display from the connecting plate 61, thereby improving the heat dissipation of the display. The specific structure of the third partition 63 can be referenced from the second partition 5.

[0085] The sunshade 7 and the connector 6 can together form a receiving space, within which the entire display can be located. At least part of the sunshade 7 extends beyond the display surface of the display to block strong light and ensure the display effect. The sunshade 7 can be integrally formed with the connector 6; or, the sunshade 7 can be connected to the connector 6 by adhesive bonding.

The first sunshade 71 may be connected to two sub-connectors 626 respectively to block light from the top of the display. The first sunshade 71 may be connected to a connecting plate 61 to ensure the stability of the overall structure; alternatively, the first sunshade 71 may be spaced apart from the connecting plate 61 to meet heat dissipation requirements. The sunshade 7 may include a second sub-sunshade, which is connected to the sub-connectors 626. The second sub-sunshade may be perpendicular to the first sunshade 71 to block light from at least one side of the display. The dimension of the second sub-sunshade along the longitudinal direction of the display may be smaller than the longitudinal dimension of the display to ensure normal tilting of the display and flexibility in the use of the electronic device.

The plurality of limiting parts 8 are used to limit the rotation of the rotating member. The rotating member can support the display at different angles by cooperating with the limiting parts 8 at different positions.

The plurality of limiting parts 8 can be arranged in a straight line or a curve, etc. The number and spacing of the limiting parts 8 can be designed according to the support angle requirements of the display in actual application. For example, the limiting parts 8 can be set to correspond to commonly used viewing angles, such as 0 degrees, 30 degrees, 45 degrees, 60 degrees, etc. For specific application scenarios, the number of limiting parts 8 can be increased or decreased, and the spacing between them can be adjusted to meet individualized requirements. The limiting parts 8 can be integrally formed with the first shell 1; alternatively, the limiting parts 8 can be connected to the first shell 1 by clamping or other means. The limiting parts 8 can be in the form of grooves, protrusions 24, buckles, etc., which can be selected according to process requirements.
