After the electronic device is turned on, if it is detected that the second signal sequence emitted by the protection device is different from the first signal sequence, it means that the placement of the conductive part does not match the initial placement, and the protection mechanism is activated to shut down the electronic device system, thereby preventing the illegal disassembler from continuing to use the electronic device, achieving the purpose of anti-tampering, that is, realizing that the protection mechanism is activated after the electronic device is disassembled without authorization, thereby avoiding unauthorized disassembly of the electronic device.

[0052] The following is a detailed description of the various embodiments of the present invention in conjunction with the accompanying drawings.

[0053] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a protection device 100, including a support frame 10, a spring-loaded support frame 20 and a plurality of conductive members 30, wherein the spring-loaded support frame 20 is movably covered on the support frame 10, and a plurality of receiving grooves 21 are provided on the side of the spring-loaded support frame 20 away from the support frame 10, and each conductive member 30 is randomly arranged in a receiving groove 21, and the number of conductive members 30 is less than the number of receiving grooves 21, so that some receiving grooves 21 are provided with conductive members 30, and other receiving grooves 21 are empty. Figure 2As shown, the spring-loaded bracket 20 is deformed and approaches the support frame 10 under the pressure of a circuit board 40, and the conductive member 30 is clamped between the spring-loaded bracket 20 and the circuit board 40, and the conductive member 30 is electrically connected to the circuit board 40. When the pressure of the circuit board 40 is released, the spring-loaded bracket 20 returns to its original state and moves away from the support frame 10 to make the conductive member 30 pop out of the accommodating groove 21.

[0054] Specifically, in the protective device 100, the support frame 10 includes a top plate 11 and side walls 12 disposed on opposite sides of the top plate 11, each side wall 12 forms a first angle α with the top plate 11; the spring-loaded support 20 is a U-shaped structure, including a main body 22 and snap-fit ​​plates 23 disposed on opposite sides of the main body 22, wherein each snap-fit ​​plate 23 forms a second angle β with the main body 22, β<α, and the two snap-fit ​​plates 23 of the spring-loaded support 20 are respectively abutted against the two side walls 12 of the support frame 12, supporting the main body 22 of the spring-loaded support 20 above the top plate 11, and the main body 22 is parallel to the top plate 11 and spaced apart from the top plate 11. A plurality of accommodating grooves 21 are disposed on the main body 22. When the main body 22 of the spring-loaded bracket 20 is supported by the circuit board 40 and moves toward the top plate 11 of the support frame 10, the snap-fit ​​plate 23 slides along the side wall 12 toward the end of the side wall 12 away from the spring-loaded bracket 20 and rotates relative to the main body 11 at the same time, so that the second angle β increases; when the circuit board 40 leaves the spring-loaded bracket 20, the restoring force of the spring-loaded bracket 20 causes the main body 22 to pull the snap-fit ​​plate 23 to restore its original state, and the snap-fit ​​plate slides along the side wall 12 toward the end of the side wall 12 close to the spring-loaded bracket 20, pushing the main body 22 away from the top plate 11, thereby popping the spring-loaded bracket 20 away from the support frame 10, and popping the conductive member 30 out of the accommodating groove 21.

[0055] In other embodiments, Figure 3 and Figure 4 For ease of display, Figure 4 The circuit board 40 is shown as transparent, the first angle α ranges from 120° to 170°, and each snap plate 23 is rotatably connected to the main body 22 through an elastic member 24. When the main body 22 of the spring-loaded bracket 20 is held by the circuit board 40 and moves toward the top plate 11 of the support frame 10, the snap plate 23 slides along the side wall 12 toward the end of the side wall 12 away from the spring-loaded bracket 20 and rotates relative to the main body 11 at the same time, so that the second angle β increases and the elastic member 24 generates an elastic force. When the circuit board 40 leaves the spring-loaded bracket 20, the elastic force of the elastic member 24 pulls the snap plate 23 to slide along the side wall 12 toward the end of the side wall 12 close to the spring-loaded bracket 20, so that the second angle β decreases and the spring-loaded bracket 20 returns to its original state, pushing the main body 22 away from the top plate 11, and then popping the spring-loaded bracket 20 away from the support frame 10, and popping the conductive member 30 out of the accommodating groove 21.

[0056] In this embodiment, the main body 22 of the spring-loaded bracket 20 is supported above the top plate 11 and does not contact the top plate 11 . When the circuit board 40 abuts against the main body 22 to deform the spring-loaded bracket 20 , the main body approaches the top plate 11 until it contacts the top plate 11 .

[0057] In this way, when the circuit board 40 presses against the spring-loaded bracket 20, causing it to deform and move closer to the support frame 10, the snap-fit ​​plate 23 slides along the side wall 12 and rotates relative to the main body 22, that is, the snap-fit ​​plate 23 resists the elastic member 24 from opening relative to each other; when the circuit board 40 leaves the spring-loaded bracket 20, the restoring force of the elastic member 24 pulls the snap-fit ​​plate 23 to return to its original state, causing the spring-loaded bracket 20 to move away from the support frame 10, and at the same time, the conductive member 30 pops out of the accommodating groove 21 under the inertia of the movement of the spring-loaded bracket 20.

[0058] In other embodiments, a limiting plate 13 is provided on the side wall 12, and the limiting plate 13 is connected to the side wall 12 at one end away from the spring-loaded bracket 20 to form a limiting groove 14, which is used to accommodate the snap-fit ​​plate 23 when the spring-loaded bracket 20 is pressed toward the support frame 10 by the circuit board 40.

[0059] In other embodiments, a buckle 131 is provided on the limiting plate 13, and the buckle 131 extends toward the limiting groove 14; a locking groove 231 corresponding to the buckle 131 is provided on the snap-fit ​​plate 23, and the buckle 131 is snapped into the locking groove 231 when the spring-loaded bracket 20 is pressed toward the support frame 10 by the circuit board 40.

[0060] In this way, when the spring-loaded bracket 20 is pressed by the circuit board and deformed, the snap plate 23 extends into the limiting groove 14, and the buckle 131 is snapped into the locking groove 231. When the circuit board 40 leaves the spring-loaded bracket 20, the restoring force of the elastic member 24 pulls the snap plate 23 to return to its original state. Since the buckle 131 is snapped into the locking groove 231, the spring-loaded bracket 20 can be prevented from being bounced off the support frame 10 and detached from the support frame 10 while the conductive member 30 is popped out of the accommodating groove 21.

[0061] like Figure 5 and Figure 6As shown, an embodiment of the present application also provides an electronic device 200, including a protective device 100, a housing 210 and a circuit board 40, wherein the housing 210 includes an upper cover 211 and a lower cover 212 snapped together with the upper cover 211, the circuit board 40 is arranged in the housing 210, and is located between the upper cover 211 and the lower cover 212, and is installed on the upper cover 211, the protective device 100 is arranged in the housing 210, and includes a support frame 10, a pressure spring bracket 20 and a plurality of conductive members 30. Among them, the support frame 10 is accommodated in the shell 210 and fixed to the lower cover 212. The spring-loaded bracket 20 is movably covered on the support frame 10. The spring-loaded bracket 20 is arranged between the support frame 10 and the circuit board 40. The spring-loaded bracket 20 is provided with a plurality of receiving grooves 21 on the side away from the support frame 10. Each conductive member 30 is randomly arranged in a receiving groove 21. The number of conductive members 30 is less than the number of receiving grooves 21. Therefore, some of the receiving grooves 21 are provided with conductive members 30, and the other part of the receiving grooves 21 are empty. When the upper cover 211 and the lower cover 212 are buckled together, the spring-loaded bracket 20 is deformed under the pressure of the circuit board 40 and approaches the support frame 10. The conductive member 30 is clamped between the spring-loaded bracket 20 and the circuit board 40, and the conductive member 30 is electrically connected to the circuit board 40 to generate a first signal sequence. The electronic device 200 can work normally upon detecting the first signal sequence. When the upper cover 211 and the circuit board 40 leave the spring-loaded bracket 20, the spring-loaded bracket 20 returns to its original state when the circuit board 40 releases the pressure and moves in a direction away from the support frame 10 to allow the conductive member 30 to pop out of the accommodating groove 21.

[0062] Specifically, in the protective device 100, the support frame 10 includes a top plate 11 and side walls 12 disposed on opposite sides of the top plate 11, one end of the side wall 12 is fixed to the lower cover 212, and the other end of the side wall 12 is connected to the top plate 11, and a first angle α is formed between each side wall 12 and the top plate 11; the pressure spring bracket 20 is a U-shaped structure, including a main body 22 and buckling plates 23 disposed on opposite sides of the main body 22, wherein a second angle β is formed between each buckling plate 23 and the main body 22, β<α, and the two buckling plates 23 of the pressure spring bracket 20 are respectively abutted on the two side walls 12 of the support frame 12, supporting the main body 22 of the pressure spring bracket 20 above the top plate 11, and the main body 22 is parallel to the top plate 11 and spaced apart from the top plate 11. A plurality of accommodating grooves 21 are disposed on the main body 22. When the main body 22 of the spring-loaded bracket 20 is supported by the circuit board 40 and moves toward the top plate 11 of the support frame 10, the snap-fit ​​plate 23 slides along the side wall 12 toward the end of the side wall 12 close to the lower cover 212 and deforms under the support of the side wall 12, so that the second angle β increases. When the circuit board 40 leaves the spring-loaded bracket 20, the restoring force of the spring-loaded bracket 20 pulls the snap-fit ​​plate 23 to restore its original state, and the snap-fit ​​plate slides along the side wall 12 toward the end of the side wall 12 away from the lower cover 212, pushing the main body 22 away from the top plate 11, thereby popping the spring-loaded bracket 20 away from the support frame 10, and popping the conductive member 30 out of the accommodating groove 21.

[0063] When using the electronic device 200 provided in the present application, the protective device 100 is placed in the housing 210 of the electronic device, the conductive member 30 is randomly placed in the receiving groove 21, and the circuit board 40 installed on the upper cover 211 is pressed against the pressure spring bracket 20, so that the pressure spring bracket 20 is deformed and approaches the support frame 10. The conductive member 30 in the receiving groove 21 is clamped between the pressure spring bracket 20 and the circuit board 40, and the conductive member 30 is electrically connected to the circuit board 40 to generate a first signal sequence. When the electronic device 200 is turned on and detects the first signal sequence, it works normally. The first signal sequence can be stored in a storage element (not shown in the figure) on the circuit board 40. If the electronic device 200 is disassembled without authorization, the upper cover 211 and the lower cover 212 are separated, and the circuit board 40 moves away from the pressure spring bracket 20 with the upper cover 211. The circuit board 40 will cancel the pressure on the pressure spring bracket 20, so that the pressure spring bracket 20 returns to its original state and moves away from the support frame 10. The conductive member 30 will be ejected from the receiving groove 21 due to the loss of the double-sided pressure of the circuit board 40 and the pressure spring bracket 20. After being ejected from the receiving groove 21, the conductive member 30 will be scattered in different corners of the housing. When the unauthorized disassembler puts the conductive member 30 back into the receiving groove 21 and re-fastens the upper cover 211 and the lower cover 212, the conductive member 30 will be electrically connected to the circuit board 40, and a second signal sequence will be generated. Since the unauthorized disassembler cannot know the original placement position of the conductive member 30, the placement position of the conductive member 30 is likely to be different from the original placement position, so the second signal sequence is likely to be different from the first signal sequence. After the electronic device 200 is turned on, it is detected that the second signal sequence emitted by the protection device 100 is different from the first signal sequence, which means that the placement position of the conductive member 30 is inconsistent with the initial placement position, and the protection mechanism is activated to shut down the electronic device 200 system, thereby preventing the illegal dismantler from continuing to use the electronic device 200, thereby achieving the purpose of anti-tampering, that is, the protection mechanism is activated after the electronic device 200 is disassembled without authorization, thereby avoiding unauthorized disassembly of the electronic device 200.

[0064] It should be understood that in the illustrated embodiment, 3 conductive members 30 and 96 receiving slots 21 are shown. There are 142,880 ways to place 3 conductive members 30 in 96 receiving slots 21, so the probability of an illegal dismantler guessing correctly is 1 / 142,880. In other embodiments, as long as the number of conductive members 30 is less than the number of receiving slots 21, the purpose of anti-tampering can be achieved. In other embodiments, the number of receiving slots 21 may be more than 8, and the number of conductive members 30 may be more than 1. In addition, the number of conductive members 30 may be between one-tenth and nine-tenths of the number of receiving slots 21.

[0065] In other embodiments, the first angle α ranges from 120° to 170°, and each snap plate 23 is rotatably connected to the main body 22 via an elastic member 24. When the main body 22 of the spring-loaded bracket 20 is held by the circuit board 40 and moves toward the top plate 11 of the support frame 10, the snap plate 23 slides along the side wall 12 toward one end of the side wall 12 close to the lower cover 212 and rotates relative to the main body 11 at the same time, so that the second angle β increases and the elastic member 24 generates an elastic force. When the circuit board 40 leaves the spring-loaded bracket 20, the elastic force of the elastic member 24 pulls the snap plate 23 to slide along the side wall 12 toward one end of the side wall 12 away from the lower cover 212, so that the second angle β decreases and the spring-loaded bracket 20 returns to its original state, pushing the main body 22 away from the top plate 11, and then popping the spring-loaded bracket 20 away from the support frame 10, and popping the conductive member 30 out of the receiving groove 21.

[0066] In this embodiment, the main body 22 of the spring-loaded bracket 20 is supported above the top plate 11 and does not contact the top plate 11 . When the circuit board 40 abuts against the main body 22 to deform the spring-loaded bracket 20 , the main body approaches the top plate 11 until it contacts the top plate 11 .

[0067] In this way, when the upper cover 211 and the lower cover 212 are buckled together, the circuit board 40 presses against the spring-loaded bracket 20, causing it to deform and move closer to the support frame 10, and the snap-fit ​​plate 23 slides along the side wall 12 and rotates relative to the main body 11, that is, the snap-fit ​​plate 23 resists the elastic member 24 from opening relative to each other; when the upper cover 211 and the lower cover 212 are separated, the circuit board 40 leaves the spring-loaded bracket 20, and the restoring force of the elastic member 24 pulls the snap-fit ​​plate 23 to restore its original state, so that the spring-loaded bracket 20 moves away from the support frame 10, and at the same time, the conductive member 30 pops out of the accommodating groove 21 under the inertia of the movement of the spring-loaded bracket 20.

[0068] In other embodiments, a limiting plate 13 is provided on the side wall 12, and the limiting plate 13 is connected to the side wall 12 at one end away from the spring-loaded bracket 20 to form a limiting groove 14, and the opening of the limiting groove 14 faces the snap-fit ​​plate 23 of the spring-loaded bracket 20, and the snap-fit ​​plate 23 is supported on one end of the side wall 12 and extends into the limiting groove 14.

[0069] In other embodiments, a buckle 131 is provided on the limiting plate 14, and the buckle 131 extends toward the limiting groove 14; a locking groove 231 corresponding to the buckle 131 is provided on the snap-fit ​​plate 23, and the buckle 131 is snapped into the locking groove 231 when the spring-loaded bracket 20 is pressed toward the support frame 10 by the circuit board 40.

[0070] In this way, when the spring-loaded bracket 20 is pressed by the circuit board and deformed, the snap plate 23 extends into the limiting groove 14, and the buckle 131 is snapped into the locking groove 231. When the circuit board 40 leaves the spring-loaded bracket 20, the restoring force of the elastic member 24 pulls the snap plate 23 to return to its original state. Since the buckle 131 is snapped into the locking groove 231, the spring-loaded bracket 20 can be prevented from being bounced off the support frame 10 and detached from the support frame 10 while the conductive member 30 is popped out of the accommodating groove 21.

[0071] In other embodiments, the pressure-spring bracket 20 also includes a fixing plate 25 connected to opposite sides of the main body, each fixing plate 25 is located between the two side walls 12, and the electronic device 200 also includes a rotating fixing member 50 rotatably disposed on the lower cover 212, the rotating fixing member 50 is disposed on opposite sides of the protective device 100 and is disposed close to the fixing plate 25, and the rotating fixing member 50 is configured to rotate to abut against the fixing plate 25 when the pressure-spring bracket 20 is pressed toward the support frame 10 by the circuit board 40, thereby fixing the pressure-spring bracket 20 to the lower cover 212.

[0072] In this way, when the upper cover 211 is separated from the lower cover 212, the circuit board 40 leaves the spring-loaded bracket 20. Since the spring-loaded bracket 20 is fixed to the lower cover 212 by the rotating fixing member 50, the spring-loaded bracket 20 will not move or return to its original state, and the conductive member 30 will not pop out of the accommodating groove 21. After the upper cover 211 and the lower cover 212 are re-fastened, the electronic device 200 can continue to work normally.

[0073] In other embodiments, the rotating fixing member 50 includes a rotating body 51 and a clamping portion 52 . The rotating body 51 is rotatably disposed on the lower cover 212 . The clamping portion 52 is connected to the rotating body 51 and is used to abut against the fixing plate 25 .

[0074] In other embodiments, Figure 6 As shown, the rotating body 51 is inserted into the lower cover 212, one end of the rotating body 51 is located inside the housing 210 and connected to the clamping portion 52, and the other end of the rotating body 51 passes through the lower cover 212 to the outside of the housing 210 and is provided with an encryption structure 53, which is used to control the rotation of the rotating body 51. For the convenience of display, Figure 6 The middle and lower cover is shown as transparent and is partially cut away along the rotating body 51 .

[0075] In this way, when an authorized person needs to disassemble the electronic device 200, he can use a password or a special tool to control the rotation of the rotating body 51 through the encryption structure 53 from outside the housing 210, so that the clamping portion 52 abuts against the fixing plate 25, thereby preventing the conductive member 30 from being ejected by the spring-loaded bracket 20 during disassembly. Unauthorized disassemblers cannot control the rotation of the rotating body 51 through the encryption structure 53 without a password or a special tool, thereby preventing unauthorized disassemblers from continuing to use the electronic device 200, achieving anti-tampering, and allowing authorized personnel to disassemble the electronic device 200.
