Description

Technical Field

[0001] This invention relates to the field of circuit board technology, and more particularly to a secure embedded circuit board. Background Technology

[0002] Embedded boards are specialized computer hardware designed for specific applications and are widely used in various products and systems requiring automated control, data processing, and communication functions. These boards integrate microprocessors (MCUs), memory, input / output interfaces, and other necessary components such as heat sinks. Most existing embedded boards use a combination of a fan and heat sink fins, with a motor driving the fan to extract heat generated by the electrical components on the board. During normal use, if one or more fan blades are damaged due to wear or aging, it can cause imbalance in the fan due to uneven mass distribution. This results in the fan experiencing additional stress during rotation, increasing its vibration amplitude. This not only causes misalignment between the fan shaft and the motor output shaft, affecting power transmission between them and leading to abnormal loads on the connection between the motor output shaft and the fan, potentially causing premature motor failure, but also transmits vibration to other connected components, affecting the normal operation of other electrical components on the board. In severe cases, it can cause solder joint breakage, pin loosening, or other mechanical damage, thus compromising the safety of the board. Summary of the Invention

[0052] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Example 1: A security-type embedded board, such as Figures 1-6 As shown, it includes: a mounting base 1, on which a circuit board 2 is mounted, and numerous electrical components are mounted on the upper side of the circuit board 2; a fixing base 3, fixedly connected to the circuit board 2; a first connecting plate 4 and a second connecting plate 401, both fixedly connected to the fixing base 3, the first connecting plate 4 and the second connecting plate 401 sharing a connecting shaft 7, on which a fan is mounted; a first mounting plate 5, fixedly connected to the fixing base 3; a drive shaft 6, rotatably connected to the first mounting plate 5, the drive shaft 6 being located on the side of the first connecting plate 4 away from the second connecting plate 401, and a drive motor for driving the drive shaft 6 to rotate is mounted on the fixing base 3; and a connecting sleeve 8, which is slidably connected to the connecting shaft 7 near the... One end of the drive shaft 6 is connected to the connecting sleeve 8 in a limiting sliding connection. Both the drive shaft 6 and the connecting shaft 7 have a sliding groove on their respective sides. A first moving block 9 is slidably connected in the sliding groove of both the drive shaft 6 and the connecting shaft 7. A first elastic element 10 is fixed between the two first moving blocks 9. The first elastic element 10 is an elastic rubber column used to switch the drive shaft 6 and the connecting shaft 7 to a flexible connection and to enable the drive shaft 6 to drive the connecting shaft 7 to rotate normally. A trigger assembly is set on the first connecting plate 4. The trigger assembly is used to change the working mode between the drive shaft 6 and the connecting shaft 7 by changing the position of the connecting sleeve 8 when the fan on the connecting shaft 7 is damaged.

[0054] In the above scheme, the middle part of the circuit board 2 is provided with a heat dissipation fin, the fan on the connecting shaft 7 is located above the heat dissipation fin on the circuit board 2; the first connecting plate 4 is located on the upper side of the second connecting plate 401; the driving motor is an existing device, which is not shown in the figure, and the driving motor is electrically connected with the control terminal, and the output shaft of the driving motor drives the driving shaft 6 to rotate; the driving shaft 6 is located above the connecting shaft 7, and the axes of the two coincide; initially, the connecting sleeve 8 is in contact with the driving shaft 6, and the connecting sleeve 8 cannot move upward relative to the driving shaft 6; in this embodiment, the first connecting plate 4 and the second connecting plate 401 are both rotationally connected with the connecting shaft 7.

[0055] The specific working process of the above scheme is as follows: when the board card is working, the driving motor drives the connecting shaft 7 and the fan on the connecting shaft 7 to rotate synchronously through the transmission of the driving shaft 6 and the connecting sleeve 8, so as to extract the heat generated by each electrical element on the circuit board 2, and cool and dissipate the heat of each electrical element on the circuit board 2, to ensure the normal use of the board card.

[0056] In the process of normal use of the board card, if one or more fan blades on the connecting shaft 7 are damaged, the vibration amplitude of the connecting shaft 7 will increase, and when the vibration amplitude of the connecting shaft 7 increases, the trigger assembly works, and the connecting sleeve 8 is driven downward to a position where it loses contact with the driving shaft 6, so that the driving shaft 6 and the connecting shaft 7 transmit power through the two first moving blocks 9 and the first elastic members 10, that is, the rigid connection between the driving shaft 6 and the connecting shaft 7 is adjusted to a flexible connection, the vibration transmission between the driving shaft 6 and the connecting shaft 7 is reduced, the amplitude of the driving shaft 6 and the driving motor is reduced, and the connecting shaft 7 can continue to rotate normally, so as to maintain the operation speed and overall performance of the board card at a high level.

[0057] Until the operation of the board card is completed, the fan blades on the connecting shaft 7 are replaced by the staff, and the connecting sleeve 8 is reset upward to the initial position, and the connection relationship between the driving shaft 6 and the connecting shaft 7 is restored to rigidity, for subsequent use.

[0058] Further, as Figures 3-6As shown, the triggering assembly includes: a moving tube 11, rotatably connected to the outside of the connecting sleeve 8, with a smooth surface at the rotatable connection between the moving tube 11 and the connecting sleeve 8 to reduce friction between them; a second elastic element 12 is fixedly connected between the moving tube 11 and the first connecting plate 4; the triggering assembly also includes: a moving plate 13, slidably connected to the connecting shaft 7, with the moving plate 13 fixedly connected to the first moving block 9 on the connecting shaft 7; a connecting ring 14, rotatably connected to the outside of the moving plate 13, with a smooth surface at the rotatable connection between the connecting ring 14 and the moving plate 13 to reduce friction between them; a third elastic element 15 is fixedly connected between the connecting ring 14 and the first connecting plate 4; and a driving assembly, disposed on the second connecting plate 401, used to change the position of the moving tube 11 and the connecting ring 14.

[0059] In the above scheme, both the second elastic element 12 and the third elastic element 15 are tension springs, and initially both the second elastic element 12 and the third elastic element 15 are in a stretched state; the contraction amount of the second elastic element 12 is greater than the height of the contact portion between the connecting sleeve 8 and the drive shaft 6, ensuring that the second elastic element 12 can drive the connecting sleeve 8 to move downward to the position where it loses contact with the drive shaft 6; initially, the vertical distance between the moving tube 11 and the connecting ring 14 is greater than the contraction amount of the second elastic element 12, avoiding collision between the moving tube 11 and the connecting ring 14 during the movement; the contraction amount of the third elastic element 15 is greater than the maximum height difference between the lower side of the drive shaft 6 and the first moving block 9 inside it initially, ensuring that the moving plate 13 can drive the upper first moving block 9 to move downward to the position where it loses contact with the drive shaft 6.

[0060] Furthermore, such as Figures 3-6 As shown, the drive assembly includes: a mounting housing 16, fixedly connected to the lower side of the second connecting plate 401; a second moving block 17, slidably connected to the interior of the mounting housing 16; a connecting rod 18, fixedly connected to the upper side of the second moving block 17, and the connecting rod 18 is fixedly connected to the connecting shaft 7; a liquid bladder 19, fixedly connected to the interior of the mounting housing 16, and the second moving block 17 is used to compress the liquid bladder 19; and a storage housing 20, on which a connector is mounted on the upper side of the first connecting plate 4, and the storage housing 20 is fixedly connected to the connector of the first connecting plate 4, and the storage housing 20 and the liquid bladder are connected. The storage tank 20 and the liquid bladder 19 are connected by a hose. A one-way valve (existing device, not shown in the figure) is provided on the hose between the storage tank 20 and the liquid bladder 19, and the flow direction of the one-way valve is from bottom to top. The first piston rod 21 is slidably connected to the inside of the storage tank 20. A fourth elastic element 22 is fixed between the first piston rod 21 and the storage tank 20. Through holes are provided on the upper right side of the moving tube 11 and the upper right side of the connecting ring 14. The first piston rod 21 slides in the through holes of the moving tube 11 and the connecting ring 14.

[0061] In the above scheme, the mounting shell 16 is located at the lower side of the second connecting plate 401; the second moving block 17 is a cylindrical block, and a smooth surface is arranged at the sliding connection position of the second moving block 17 and the mounting shell 16; the liquid tank 19 can be provided with a plurality of specific quantities, which are selected by the staff, and four are taken as examples in the figure and the text; the liquid tank 19 stores hydraulic oil; the hose between the storage shell 20 and the liquid tank 19 passes through the mounting shell 16; the storage shell 20 is located at the upper side of the first connecting plate 4, and the fourth elastic member 22 is a spring; initially, the first piston rod 21 is located in the through hole of the moving pipe 11 and the connecting ring 14, and the first piston rod 21 does not contact the connecting sleeve 8, so as to avoid friction between the connecting sleeve 8 and the first piston rod 21.

[0062] The specific working process of the above scheme is as follows: when the amplitude of the connecting shaft 7 increases, the vibration amplitude of the connecting rod 18 increases synchronously, that is, the shaking amplitude of the connecting rod 18 increases, so that the distance of the transverse movement of the second moving block 17 increases, and the following is described by taking the process of the right movement of the second moving block 17 as an example:

[0063] After the second moving block 17 moves to the right and contacts the right liquid tank 19, the second moving block 17 continues to move to the right and squeezes the right liquid tank 19, so that the hydraulic oil in the right liquid tank 19 is transported to the storage shell 20 through the hose (at this time, the hydraulic oil in the storage shell 20 cannot flow back to the liquid tank 19 due to the action of the one-way valve on the hose), so that the first piston rod 21 is pressed to move to the right, and the fourth elastic member 22 is compressed to store force; when the first piston rod 21 moves to the right and loses contact with the moving pipe 11, the moving pipe 11 drives the connecting sleeve 8 to move downward together under the action of the second elastic member 12, so as to convert the rigid connection relationship between the drive shaft 6 and the connecting shaft 7 into a flexible connection, and reduce the shaking amplitude of the connecting shaft 7 and the fan blades thereon.

[0064] If the moving range of the second moving block 17 is still not reduced after the flexible connection between the driving shaft 6 and the connecting shaft 7, it proves that the damage of the fan blades on the connecting shaft 7 is more serious, so the second moving block 17 still squeezes the right liquid bag 19 during the right movement, continues to transport the hydraulic oil in the right liquid bag 19 into the storage shell 20, and makes the first piston rod 21 continue to move to the right. When the first piston rod 21 moves to the right and loses contact with the connecting ring 14, the connecting ring 14 is driven by the moving plate 13 to move the lower first moving block 9 downward under the action of the third elastic member 15, and then the first elastic member 10 is driven to move downward synchronously with the upper first moving block 9. When the third elastic member 15 returns to the unstretched state, the connecting ring 14 stops moving, and at this time the upper first moving block 9 loses contact with the driving shaft 6, that is, the connecting shaft 7 is disconnected from the driving shaft 6, so that the connecting shaft 7 no longer rotates, avoiding affecting the stability of the remaining electrical elements on the circuit board 2, and then affecting the normal use of the remaining electrical elements on the circuit board 2.

[0065] The working processes of the remaining three liquid bags 19 will not be described in detail, please refer to the above.

[0066] After disconnecting the connecting shaft 7 from the driving shaft 6, the staff turns off the driving motor on the fixed seat 3 to stop the driving shaft 6 from rotating, saves the operation data of the board card, replaces the fan blades on the connecting shaft 7, moves the moving pipe 11 and the connecting ring 14 upward to reset them to the initial position, and stretches the second elastic member 12 and the third elastic member 15 again. Then the staff pumps out the hydraulic oil transported into the storage shell 20, and moves the first piston rod 21 to the left under the action of the fourth elastic member 22. After the first piston rod 21 is reinserted into the through hole of the moving pipe 11 and the connecting ring 14 (the first piston rod 21 repositions the moving pipe 11 and the connecting ring 14), the first piston rod 21 moves to the left limit position. Then the staff replenishes the consumed hydraulic oil in the liquid bag 19, and puts the board card into use again.

[0067] Example 2: based on example 1, as shown in Figure 5 The moving ring 701 has two, and is fixed to the connecting shaft 7. The first connecting plate 4 and the second connecting plate 401 are provided with storage cavities 702. The moving ring 701 slides in the adjacent storage cavities 702. The storage cavities 702 are circular rings. The inner diameter of the storage cavities 702 is smaller than the outer diameter of the moving ring 701. The outer diameter of the moving ring 701 is smaller than the outer diameter of the storage cavities 702. A damping device can be arranged between the storage cavities 702 and the adjacent moving ring 701. The damping device is an existing device, which is not shown in the figure. A spring or other damping workpiece can be selected.

[0068] In this embodiment, the connecting shaft 7 has no direct connection relationship with the first connecting plate 4 and the second connecting plate 401.

[0069] In the process of rotating the connecting shaft 7, the connecting shaft 7 drives the two moving rings 701 to rotate synchronously in the adjacent storage cavities 702, the damping device in the storage cavity 702 reduces the vibration of the moving ring 701 during normal rotation, thereby reducing the vibration of the circuit board 2 during normal use, and prolonging the service life of each electrical element on the circuit board 2.

[0070] Embodiment 3: based on embodiment 2, as shown in Figure 1 、 Figure 2 、 Figure 7 and Figure 8 , further comprising: a mounting frame 23 fixedly connected to the upper side of the mounting base 1; a liquid storage shell 24 fixedly connected to the upper side of the mounting frame 23; a liquid discharge pipe 25 fixedly connected to the lower side of the mounting frame 23, the liquid discharge pipe 25 communicates with the liquid storage shell 24 through a hose, and the liquid storage shell 24 and the liquid discharge pipe 25 both store insulating liquid; a second piston rod 26 slidingly connected in the liquid storage shell 24, a fifth elastic member 251 fixedly connected between the second piston rod 26 and the liquid discharge pipe 25; a second mounting plate 27 fixedly connected to the rear end of the second piston rod 26; a limiting block 28, the rear part of the upper side of the mounting frame 23 is provided with a cavity, the limiting block 28 is slidingly connected in the cavity of the mounting frame 23, a sixth elastic member 29 is fixedly connected between the limiting block 28 and the mounting frame 23, the cavity of the mounting frame 23 communicates with the liquid tank 19 through a hose, and the limiting block 28 is used for limiting the second mounting plate 27.

[0071] In the above scheme, the number of mounting frames 23 can be set to multiple, and both the figure and the text are represented by two as an example; the liquid in the liquid storage shell 24 flows into the liquid discharge pipe 25 through the hose thereon; initially, the second piston rod 26 has moved to the limit position, the fifth elastic member 251 is a tension spring, and initially the fifth elastic member 251 is in the stretched state; the sixth elastic member 29 is a spring.

[0072] Further, as shown in Figure 7 , the insulating liquid in the liquid storage shell 24 and the liquid discharge pipe 25 is fluorinated liquid, and a plurality of atomizing nozzles are installed on the side of the liquid discharge pipe 25 close to the mounting base 1, for spraying fluorinated liquid on the circuit board 2 when the connecting shaft 7 stops rotating, to perform heat dissipation treatment on the circuit board 2, the atomizing nozzles are existing devices, and they are not shown in the figure.

[0073] The specific operation process of the above scheme is as follows: while the liquid bag 19 transports hydraulic oil into the storage shell 20 through the hose thereon, the hydraulic oil in the liquid bag 19 flows into the cavities of the two mounting frames 23 through the hose thereon at the same time, so that the two limiting blocks 28 are synchronously moved downward under the extrusion force and compress the two sixth elastic members 29, and when the two limiting blocks 28 are respectively moved downward to lose contact with the adjacent second mounting plate 27 (at this time, the driving shaft 6 and the connecting shaft 7 are no longer connected), the second mounting plate 27 is no longer limited by the adjacent limiting block 28, so that the two fifth elastic members 251 respectively drive the adjacent second piston rod 26 to move forward, and the fluorinated liquid in the two liquid storage shells 24 is respectively extruded into the adjacent liquid discharge pipe 25 and sprayed outward along the atomizing nozzle on the liquid discharge pipe 25, thereby cooling the electrical elements on the circuit board 2, avoiding the situation that after the connecting shaft 7 stops rotating, the electrical elements on the circuit board 2 cannot be cooled, resulting in the decrease of the overall operation speed and performance of the board card, causing the operation time to be prolonged, and even affecting the stability of the electronic signal, thereby affecting the stability of the entire board card system.

[0074] Until the end of operation, the workers first reset the two second mounting plates 27 to the initial position, and supplement the consumed fluorinated liquid in the two liquid storage shells 24, and after the two liquid storage shells 24 are filled with fluorinated liquid again, the workers replace the fan blades on the connecting shaft 7, reset the first piston rod 21 to the initial position according to the above operation, and pump out the hydraulic oil transported into the cavities of the two mounting frames 23, so that the two limiting blocks 28 can be respectively reset upward under the action of the adjacent sixth elastic member 29, and the two second mounting plates 27 are repositioned for subsequent use.

[0075] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacement or change according to the technical solution and the improvement concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
