Please refer to Figures 1 to 5 together. Figure 1 is a schematic diagram of the back of the first embodiment of the electronic device of the present invention, Figure 2 is a partially enlarged schematic diagram of this embodiment, Figure 3 is a partially exploded schematic diagram of this embodiment, Figure 4 is an exploded schematic diagram of the housing and the detachable electronic module of this embodiment, and Figure 5 is an exploded schematic diagram of the housing and the push-pull member of this embodiment.

The electronic device 100 of the present invention includes a housing 1, three removable electronic modules 2 and three switch mechanisms 3. Each removable electronic module 2 is detachably mounted on the housing 1, and each switch mechanism 3 is disposed on the housing 1, and each switch mechanism 3 is disposed adjacent to one of the removable electronic modules 2. Each switch mechanism 3 is used to provide user operation so that the removable electronic module 2 is fixed to the housing 1. The number of removable electronic modules 2 and switch mechanisms 3 included in the electronic device 100 can be changed according to actual needs and is not limited here.

The electronic device 100 can be applied as a laptop, tablet computer, etc., and is particularly suitable for application as a rugged computer, which is suitable for use by units that need to process sensitive data, such as military units, intelligence units, etc., but not limited thereto. If the electronic device 100 is applied as a laptop, the electronic device 100 includes components included in a laptop, such as a screen, a keyboard, and a hard drive. In the following description, only the differences between the electronic device 100 of the present invention and the known laptop will be described. The undescribed parts can be designed according to actual needs and with reference to the known laptop.

The casing 1 includes a casing body 10 and three switch casings 11. The casing body 10 includes three accommodating grooves 101, each of which is used to accommodate a removable electronic module 2. The casing body 10 is used as the outer shell and main supporting structure of the electronic device 100, and the three switch casings 11 are fixed to the casing body 10, and each switch casing 11 is used to shield and limit the range of movement of the push member 31 of the switch mechanism 3.

Each detachable electronic module 2 is detachably mounted in the receiving slot 101 of the housing 1. The switch mechanism 3 includes a push member 31 and a stop member 32. The push member 31 can move between a locked position and an unlocked position relative to the housing 1. In practical applications, the housing 1 may have a related guide structure (such as various slide grooves, slide rails, etc.), and a part of the push member 31 is slidably connected to the guide structure, and the push member 31 can slide relative to the housing 1 through the guide structure. The stop member 32 is, for example, a screw, but is not limited thereto. In the embodiment where the stopper 32 is a screw, an operating hole of the stopper 32 is not a cross-shaped or flat-shaped hole, but a hole of a special shape, that is, the stopper 32 cannot be directly removed using common operating tools such as a cross screwdriver or a flat-shaped screwdriver.

As shown in FIG. 2 , when the push member 31 is in the upper locking position, the push member 31 will restrict the removable electronic module 2, and the removable electronic module 2 will be fixed to the housing 1. At this time, the user basically cannot directly pull the removable electronic module 2 to remove it from the accommodating slot 101 (as shown in FIG. 4 ). In the scenario shown in FIG. 2 , the limiter 32 is in a restricted position. At this time, the push member 31 will be restricted by the limiter 32, and the push member 31 will not be operated and move from the upper locking position shown in FIG. 2 to the unlocking position shown in FIG. 4 . That is to say, in the scenario shown in FIG. 2 , the user cannot remove the removable electronic module 2 from the accommodating slot 101 by hand without tools (such as a screwdriver, etc.).

As shown in FIGS. 3 to 5 , when the user uses a relevant operating tool (such as a screwdriver) to remove the limiter 32 from the housing 1, the pusher 31 will no longer be restricted by the limiter 32, and the pusher 31 can be pushed to the unlocking position shown in FIG. 3 , and then the user can manually move the detachable electronic module 2 to remove the detachable electronic module 2 from the receiving slot 101.

As described above, the electronic device 100 of the present invention allows the user to fix the removable electronic module 2 on the case 1 according to actual needs through the mutual cooperation of the case 1, the switch mechanism 3 and the removable electronic module 2, so as to prevent the removable electronic module 2 from being easily removed from the case 1 by an unscrupulous person, and to prevent the removable electronic module 2 from being easily removed from the case 1.

More specifically, in the military or intelligence units that need to handle sensitive data, in order to prevent sensitive data from being leaked, the relevant sensitive data will be stored in a solid-state hard drive (SSD), which can be quickly replaced and installed on the laptop. When the relevant personnel are off duty, the SSD will be removed and placed in a specific place for safekeeping. When the relevant personnel are at work, the SSD will be installed on the laptop. However, in this application scenario, when the SSD is installed on the laptop, when the laptop is subjected to unexpected external forces, the SSD will easily detach from the laptop, causing trouble to the user. In addition, when the SSD is installed on the laptop, the SSD can be easily removed from the laptop by someone with ulterior motives.

The electronic device 100 of the present invention can allow relevant personnel to place the limiter 32 in a restricted position through the design of the switch mechanism 3, so that the pusher 31 cannot be operated, thereby fixing the removable electronic module 2 on the housing 1, thereby preventing the removable electronic module 2 from being separated from the housing 1, and effectively solving the above-mentioned problems existing in the known rugged notebook. In addition, in the embodiment where the limiter 32 is a screw, the size of the screw hole of the limiter 32, the shape of the operating hole, etc. can also be specially designed, thereby, even if someone steals the electronic device 100, they will not be able to quickly remove the removable electronic module 2 from the housing 1 because they do not have appropriate tools.

Please refer to Figures 5 to 9 together. Figure 6 is a schematic cross-sectional view of the first embodiment of the electronic device of the present invention along the section line VI-VI of Figure 2, Figure 7 is another schematic cross-sectional view of this embodiment, Figure 8 is a schematic cross-sectional view of this embodiment along the section line VIII-VIII of Figure 4, and Figure 9 is another schematic cross-sectional view of this embodiment.

The switch housing 11 of the housing 1 is fixed to the housing body 10 of the housing 1 by means of screws, buckles, etc. The switch housing 11 includes a ring side wall 111 and an opening 112. The ring side wall 111 is arranged around the opening 112, and the opening 112 is a hole that passes through the switch housing 11. When the switch housing 11 is fixed to the housing body 10, the switch housing 11 and the housing body 10 will jointly form an activity space S. The activity space S is located in the housing 1, and the activity space S can be connected to the outside through the opening 112.

The push member 31 includes a body 311 and an operating portion 312. The body 311 is located in the activity space S, and the operating portion 312 protrudes from the opening 112. The operating portion 312 is used to provide a user with an operation so that the push member 31 moves between the locking position and the unlocking position. The body 311 may include a lock hole 3111, and the limit member 32 is a screw, and the limit member 32 can be locked in the lock hole 3111.

As shown in Figs. 2, 3, 6 and 7, when the push member 31 is in the upper locking position shown in Fig. 3, the lock hole 3111 of the body 311 will be exposed at the opening 112, and the lock hole 3111 of the body 311 and the opening 112 of the switch housing 11 are interconnected. At this time, the limit member 32 can pass through the opening 112 and lock with the lock hole 3111. When the limit member 32 and the lock hole 3111 are locked with each other, the limit member 32 is in the restricted position, and a head 321 of the limit member 32 is located in the opening 112, and the head 321 is located between the operating part 312 and the surrounding side wall 111, whereby the operating part 312 will be stuck by the head 321 and cannot move to the unlocking position shown in Fig. 4.

As shown in Figures 3, 4, 8 and 9, when the limiter 32 removes the lock hole 3111 and the limiter 32 is no longer in the restricted position, the push member 31 originally in the upper locking position shown in Figure 3 can be pushed and moved to the unlocking position shown in Figure 4. When the push member 31 is in the unlocking position, the lock hole 3111 will not be exposed from the opening 112, and the lock hole 3111 will be located in the switch housing 11.

As shown in FIG. 4 , in actual application, the removable electronic module 2 may include a housing 21, a plurality of electronic modules 22 and a connector 23, and the electronic module 22 is disposed in the housing 21. The electronic module 22 may include, for example, a circuit board, a plurality of memories, etc., and the electronic module 22 may be a solid state drive (SSD). A portion of the connector 23 is exposed from the housing 21, and the connector 23 is used to connect to the connector in the housing 1. The housing 21 includes two snap-fitting portions 211, and the two snap-fitting portions 211 are disposed at intervals. When the removable electronic module 2 is installed in the receiving slot 101, the two snap-fitting portions 211 are disposed adjacent to the switch mechanism 3. As shown in Figures 4 and 5, the main body 311 of the push member 31 also includes two blocking structures 313, and the two blocking structures 313 are arranged at intervals.

As shown in FIG6 and FIG7, when the push member 31 is in the upper locking position, the blocking structure 313 of the push member 31 is located above the engaging portion 211 of the removable electronic module 2. At this time, even if the limiting member 32 is not locked in the locking hole 3111, the removable electronic module 2 will still be unable to escape from the accommodating slot 101 because the engaging portion 211 is blocked by the blocking structure 313.

As shown in FIG8 and FIG9, when the push member 31 is in the unlocked position, the lock hole 3111 will not be exposed from the opening 112, and the blocking structure 313 of the push member 31 will no longer be located above the engaging portion 211 of the removable electronic module 2. At this time, the relevant personnel can pull the removable electronic module 2 to remove the removable electronic module 2 from the accommodating slot 101.

As described above, in one of the specific embodiments, the connection relationship and position relationship between the housing 1, the limiting member 32, the pushing member 31 and the removable electronic module 2 can be implemented according to the uploaded instructions, but is not limited thereto.

Please refer to FIG. 10, which is a cross-sectional schematic diagram of the second embodiment of the electronic device of the present invention. The biggest difference between this embodiment and the embodiment shown in FIG. 6 is that the position of the lock hole 3111 included in the body 311 of the push member 31 is different from that of the embodiment of FIG. 6, and the switch housing 11 of the housing 1 includes a through hole 113. When the push member 31 is in the upper locking position, the lock hole 3111 of the push member 31 and the through hole 113 of the switch housing 11 are interconnected, and the limit member 32 can pass through the through hole 113 and lock with the lock hole 3111, thereby, the push member 31 will be restricted by the limit member 32 and cannot move to the unlocking position.

Please refer to FIG. 11, which is a cross-sectional schematic diagram of the third embodiment of the electronic device of the present invention. The biggest difference between this embodiment and the embodiment shown in FIG. 6 is that the push member 31 does not have a lock hole, while the switch housing 11 has a lock hole 114. When the push member 31 is in the upper locking position and the push member 31 is locked in the lock hole 114 of the switch housing 11, a part of the limit member 32 is located in the active space S, whereby the push member 31 will be blocked by the limit member 32 located in the active space S and cannot move to the unlocking position. It should be noted that the stopper 32 that is locked with the lock hole 114 is mainly used to prevent the push member 31 from moving to the unlocking position. Therefore, when the stopper 32 and the lock hole 114 are locked with each other, the part of the stopper 32 located in the active space S will correspond to the path of the push member 31 moving from the upper locking position to the unlocking position.

Please refer to Figures 12 to 14 together. Figures 12 and 13 are cross-sectional schematic diagrams of the fourth embodiment of the electronic device of the present invention in different states, and Figure 14 is a block schematic diagram of this embodiment. The electronic device 100 may also include an electromagnet 4 and a control module 5. The electromagnet 4 is electrically connected to the control module 5. The control module 5 may be, for example, a microprocessor independent of the central processing unit 6 of a laptop computer. It should be noted that in special applications, the control module 5 and the central processing unit 6 may also be integrated into the same module. The control module 5 can control the electromagnet 4 to change the magnetism of the electromagnet 4. The electromagnet 4 is disposed in the housing 1, and the electromagnet 4 is disposed adjacent to the push member 31. The limiter 32 is disposed in the housing 1, and at least a portion of the limiter 32 is magnetic. In practical applications, the limiter 32 contains a permanent magnet 322, for example. The limiter 32 can move in an active channel 12 in the housing 1. In practical applications, the active channel 12 can be formed on a related supporting structure in the housing 1, for example, or the active channel 12 can be formed on a circuit board, and the circuit board is disposed in the housing 1.

As shown in FIG12, when the push member 31 is in the upper locking position and the control module 5 controls the magnetism of the electromagnet 4 to be the same as the magnetism in the limit member 32, the permanent magnet 322 in the limit member 32 will move to the restricted position shown in FIG12 in the movable channel 12 due to the repulsion of like poles. When the limit member 32 moves to the restricted position, a part of the limit member 32 will be located in a through hole 314 of the push member 31, thereby, the push member 31 will be restricted by the limit member 32 and cannot move to the unlocking position.

As shown in FIG13, when the control module 5 controls the electromagnet 4 so that the magnetism of the electromagnet 4 is opposite to that of the limiter 32, the permanent magnet 322 of the limiter 32 will move from the restricted position shown in FIG12 to the unrestricted position shown in FIG13 due to the attraction between opposite poles, thereby a part of the limiter 32 will no longer be located in the through hole 314 of the pusher 31. When the limiter 32 is no longer located in the through hole 314 of the pusher 31, the pusher 31 can move from the locked position to the unlocked position.

As described above, in actual applications, a central processing unit 6 of the electronic device 100 may, for example, run a decryption application 7. The decryption application may, for example, be installed and executed in an operating system, but is not limited thereto. In different embodiments, the decryption application may, for example, be installed and executed in a BIOS.

When the central processor 6 runs the unlocking application, the user can see an application interface on a display of the electronic device 100, for example, and the application interface displays fields requiring the user to enter an account and password. When the user enters the correct account and password in the application interface, the processor will control the magnetism of the electromagnet 4 through the control module 5 to move the limiter 32 to the non-restricted position, so that the pusher 31 can move from the locked position to the unlocked position. On the contrary, if the account and password are entered incorrectly, the central processor will not change the polarity of the electromagnet 4 through the control module 5, and the limiter 32 will continue to be in the restricted position, thereby preventing the pusher 31 from moving to the unlocked position.

It should be noted that the setting positions of the limiter 32 and the electromagnet 4 in this embodiment are only one exemplary embodiment. In different embodiments, the setting positions of the limiter 32 and the electromagnet 4 can also be modified accordingly with reference to Figures 10 and 11. Of course, in different embodiments, as long as the limiter 32 is affected by the electromagnet 4 and is located in the restricted position, at least a part of the limiter 32 is located on the path of the push member 31 moving from the upper locking position to the unlocking position, the setting positions of the electromagnet 4 and the limiter 32 can be changed according to needs.

Please refer to Figures 15 to 19 together. Figure 15 is a schematic diagram of the fifth embodiment of the electronic device of the present invention, Figure 16 is a partially enlarged schematic diagram of this embodiment, Figure 17 is a partially exploded schematic diagram of this embodiment, Figure 18 is a cross-sectional schematic diagram of this embodiment along the section line XVIII-XVIII of Figure 16, and Figure 19 is another cross-sectional schematic diagram of this embodiment.

In this embodiment, the interior of the detachable electronic module 2, for example, includes a battery. As shown in Figures 15 to 17, the biggest difference between this embodiment and the aforementioned embodiment is that the switch mechanism 3 also includes an elastic member 33 and two locking members 34, and the push member 31 includes a first member 315 and a second member 316. The first member 315 is fixed to the second member 316. The second member 316 can be movably disposed on the housing body 10.

In practical applications, the second component 316 includes two slide grooves 3161, and the two locking members 34 are locked with the two lock holes 102 of the housing body 10 through the two slide grooves 3161, so that the second component 316 is slidably arranged on the housing body 10. The first component 315 includes the aforementioned operating portion 312. The elastic member 33 is, for example, a spring. The two ends of the elastic member 33 are respectively fixed to the housing body 10 and the second component 316. The second component 316 includes two blocking structures 313. For the description of the mutual cooperation between the blocking structure 313 and the engaging portion of the detachable electronic module 2, please refer to the aforementioned embodiment, which will not be repeated here.

As shown in Figures 17 and 18, the first component 315 has a through hole 3151, and the housing body 10 has a lock hole 115. When the push member 31 is in the upper locking position, the through hole 3151 and the lock hole 115 are connected to each other, and the through hole 3151 and the lock hole 115 are exposed from the opening 112 of the switch housing 11, and the limiter 32 can pass through the through hole 3151 and lock with the lock hole 115. Thus, the first component 315 and the second component 316 will be fixed to the housing body 10 by the limiter 32, and the push member 31 will not be able to move to the unlocking position.

As shown in FIG. 19 , when the push member 31 is in the unlocking position, the through hole 3151 of the first component 315 will be located in the active space S and will not be exposed from the opening 112, and the elastic member 33 will be in a stretched state. In this state, when the user no longer operates the push member 31, the push member 31 will be affected by the elastic restoring force of the elastic member 33 and move from the unlocking position to the locking position.

It should be noted that in one variation of the present embodiment, the first component 315 and the second component 316 may be integrally formed; in another variation, the electronic device 100 may not include the elastic component 33. In any of the aforementioned embodiments, the elastic component 33 of the present embodiment may also be added as required. The aforementioned embodiment of the electromagnetic iron 4 may also be combined with the push-pull component 31 of the present embodiment including the first component 315 and the second component 316 to form a new embodiment.

In summary, the electronic device of the present invention can prevent the detachable electronic module from being easily removed from the case by the design of the push-pull member and the limit member included in the switch mechanism according to actual needs, thereby effectively improving the problem that the detachable electronic module (such as a battery or a solid state hard disk, etc.) included in the conventional rugged notebook computer is easily removed from the case or stolen.

The above is only the best feasible embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the contents of the specification and drawings of the present invention are included in the protection scope of the present invention.
