Description

Technical Field

[0001] This invention relates to the field of electric roller technology, and in particular to a computer chassis movement alarm device based on information security. Background Technology

[0002] A computer case is a crucial piece of computer hardware; every computer has one. From a system security perspective, computer chips and hardware devices can also pose threats to system security. For example, the CPU integrates the instruction set that runs the operating system. This instruction code is confidential, and we don't know its security level.

[0003] Based on the above, most computers use physical locks, but these locks are usually insufficient to prevent theft because they are easy to pry open and cannot provide timely alarms or other warnings when stolen, resulting in serious losses. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a computer chassis movement alarm device based on information security.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A computer chassis relocation alarm device based on information security includes a chassis body, a bottom cover fixedly connected to the lower side wall of the chassis body, a battery box installed on the inner top wall of the chassis body containing a battery, a buzzer installed on the inner wall of the chassis body, and multiple speaker holes on both side walls of the chassis body. A relocation alarm mechanism is located inside the bottom cover, comprising a ceramic cylinder mounted on the inner top wall of the bottom cover, with a resistance wire wound around its outer wall. A crossbar connects the two inner walls of the bottom cover, and an insulating block is slidably fitted onto the outer wall of the crossbar. A conductive rod that slides against the surface of the resistance wire is fixedly connected to the upper side wall of the insulating block. A moving disk is fixedly connected to the lower side wall of the insulating block. Springs one that are fixedly connected to the inner walls of both sides of the bottom cover are respectively connected to the outer wall of the insulating block. A grounding rod is slidably inserted at the connection between the bottom cover and the chassis body. An anti-blocking mechanism is provided between the grounding rod and multiple speaker holes on both sides. A guide rod that is fixedly connected to the top wall of the chassis body is slidably inserted at the top of the grounding rod. A spring two is fixedly connected between the grounding rod and the inner top wall of the chassis body. A lifting alarm mechanism is provided between the grounding rod and the resistance wire.

[0007] Preferably, the lifting alarm mechanism includes a geared disc installed on the front wall of the chassis body. The outer wall of the grounding rod has a toothed groove that meshes with the geared disc. A cylindrical pin is fixedly connected to the front wall of the geared disc. An insulating strip that penetrates the inner bottom wall of the chassis body and the inner top wall of the bottom cover is movably sleeved on the outer wall of the cylindrical pin. A limiting rod that is fixedly connected between the inner walls of both sides of the bottom cover is slidably inserted into the side wall of the insulating strip. A sliding groove that matches the cylindrical pin is opened on the outer wall of the insulating strip. A through groove that matches the insulating strip is opened at the connection between the chassis body and the bottom cover. A conductive rod that slides against the surface of the resistance wire is fixedly connected to the side wall of the insulating strip near the ceramic cylinder.

[0008] Preferably, the battery is a rechargeable lithium battery, and a charger electrically connected to the battery is fixedly connected to the inner top wall of the chassis body.

[0009] Preferably, the anti-blocking mechanism includes a gear located on the rear side of the grounding rod and meshing with a tooth groove. A rotating shaft is fixedly installed through the middle of the gear and installed between the inner walls of both sides of the chassis body. Two fan blades are symmetrically fixedly sleeved on the outer wall of the rotating shaft, which are respectively opposite to multiple speaker holes on both sides.

[0010] Preferably, the front wall of the grounding rod is vertically and equally spaced with multiple columns, and two vibration mechanisms are provided on the outer side of the multiple columns. The vibration mechanism includes a notched ring fixedly connected to the inner wall of the front side of the chassis body, and vibrating balls are fixedly connected to both ends of the notched ring. A vibrating wing is fixedly connected to the outer wall of the notched ring and located between two columns on the same side between the two vibrating balls.

[0011] Preferably, a rubber sheet is fixedly connected to the lower side wall of the moving disk.

[0012] Preferably, the gear disc has a fixed shaft installed on the inner front wall of the chassis body at its center, and the insulating strip is located below the fixed shaft.

[0013] Preferably, each of the columns and each vibrating ball is made of iron.

[0014] Preferably, the connection between the chassis body and the bottom cover is provided with a sliding hole that matches the grounding rod, and the inner wall of the sliding hole is provided with a through groove that matches each column.

[0015] Compared with existing technologies, the advantages of this computer chassis relocation alarm device based on information security are as follows:

[0016] 1. By setting up conductive rods and a movable tray, when the computer case is moved, the friction between the rubber sheet and the ground or tabletop causes the conductive rod to move on the resistance wire, increasing the current value in the circuit and the voltage value across the buzzer, thereby causing the buzzer to sound an alarm in a timely manner. At the same time, the greater the movement of the computer case, the louder the alarm sound of the buzzer will become, thus improving the alarm effect of the computer case and preventing serious damage.

[0017] 2. The device is equipped with a ground contact rod and a conductive rod. When the chassis is lifted, the conductive rod moves along the resistance wire, increasing the voltage across the buzzer and causing it to sound an alarm in a timely manner. The greater the chassis is lifted, the louder the alarm will sound, thus improving the alarm effect of the computer chassis and preventing serious damage. Therefore, the device can sound an alarm whether the chassis is lifted or moved, providing double protection and greatly improving the alarm effect of the device.

[0018] 3. The fan blades are designed so that when the chassis is lifted and the grounding rod moves, the meshing of the gears and the toothed disc will drive the two fan blades to rotate, thereby blowing out the dust in each speaker hole. This ensures that the sound emitted by the buzzer alarm can be quickly transmitted to the outside, avoiding serious damage.

[0019] 4. The device is equipped with vibrating wings. The vibration of the two vibrating balls during each interval of the wing can dislodge the dust in each speaker hole, further ensuring the unobstructed flow of the sound in each speaker hole. This allows the sound emitted by the buzzer to spread smoothly and quickly, ensuring the alarm effect of the device.

[0020] 5. The device is equipped with iron columns and vibrating balls. When each column moves each vibrating fin, and when each vibrating fin intermittently strikes each vibrating ball, a certain amount of collision sound can be emitted through the rigid collision between their contact points, which improves the alarm effect of the device.

[0021] In summary, this invention provides a double safety measure by automatically triggering an alarm sound when the computer case is moved or lifted. Furthermore, the alarm sound increases with the magnitude of the movement or lifting, thus enhancing the alarm effect of the computer case and preventing serious damage. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Reference Figure 1-6A computer chassis relocation alarm device based on information security includes a chassis body 1, a bottom cover 2 fixedly connected to the lower side wall of the chassis body 1, a battery box 3 installed on the inner top wall of the chassis body 1, a battery (a rechargeable lithium battery) inside the battery box 3, and a charger 21 electrically connected to the battery fixedly connected to the inner top wall of the chassis body 1. Each time the computer chassis body 1 is used and the power of the chassis body 1 is turned on, the battery can be charged using the charger 21, thereby ensuring that the battery has sufficient power to ensure continuous operation when the power of the chassis body 1 is off.

[0032] A buzzer 4 is installed on the inner wall of the chassis body 1. Multiple sound holes 5 are opened on both sides of the chassis body 1. When the buzzer 4 works and emits a sound, the sound can be quickly diffused from inside the chassis body 1 to the outside of the chassis body 1 through the multiple sound holes 5 on both sides, which is conducive to the rapid propagation of the alarm sound.

[0033] The bottom cover 2 is equipped with a movement alarm mechanism, which includes a ceramic cylinder 6 installed on the top wall of the bottom cover 2. The outer wall of the ceramic cylinder 6 is wound with a resistance wire 7. A crossbar is connected between the inner walls of both sides of the bottom cover 2. An insulating block 8 is slidably sleeved on the outer wall of the crossbar. A conductive rod 9 is fixedly connected to the upper side wall of the insulating block 8 and slides against the surface of the resistance wire 7. A moving plate 10 is fixedly connected to the lower side wall of the insulating block 8. A rubber sheet 22 is fixedly connected to the lower side wall of the moving plate 10. The rubber sheet 22 can increase the friction between the moving plate 10 and the ground, so that when someone moves the main body of the machine box 1, the friction between the rubber sheet 22 and the ground or table can be used to easily move the moving plate 10.

[0034] The outer wall of the insulating block 8 is connected to springs 11 that are fixedly connected to the inner walls of both sides of the bottom cover 2. In use, the chassis body 1 is first placed vertically on the ground or table. The initial position of the conductive rod 9 is in the middle of the resistance wire 7, and the wiring connections between the conductive rod 9, battery, buzzer 4, and resistance wire 7 are as shown in the attached diagram. Figure 3As shown, when the chassis 1 is placed vertically on the ground or table, the rubber sheet 22 is in close contact with the ground or table, and the conductive rod 9 is in the middle of the resistance wire 7. At this time, the resistance of the resistance wire 7 in the circuit is at its maximum, and the current in the entire circuit is at its minimum. Therefore, the voltage across the buzzer 4 is at its minimum, and the buzzer 4 cannot make a sound. Then, when someone moves the chassis 1, the friction between the rubber sheet 22 and the ground or table will cause the insulating block 8 to move on the crossbar, thereby causing the conductive rod 9 to move synchronously and change its position on the resistance wire 7. This reduces the resistance of the resistance wire 7 in the circuit, increases the current in the circuit and the voltage across the buzzer 4, and causes the buzzer 4 to make an alarm sound in time, achieving the alarm effect. At the same time, the greater the range of movement of the chassis 1, the greater the distance that the moving plate 10 moves the conductive rod 9, and the greater the voltage across the buzzer 4. The alarm sound of the buzzer 4 will become louder and louder, thereby improving the alarm effect of the computer chassis and avoiding serious damage.

[0035] A ground contact rod 12 is slidably inserted at the connection between the bottom cover 2 and the chassis body 1. A guide rod fixedly connected to the inner top wall of the chassis body 1 is slidably inserted at the top of the ground contact rod 12. A spring 13 is fixedly connected between the ground contact rod 12 and the inner top wall of the chassis body 1. When the chassis body 1 is placed on the ground or table and the bottom cover 2 touches the ground, under the action of the chassis body 1's own weight, the ground or table pushes the bottom end of the ground contact rod 12, causing it to move upward and compress the spring 13, putting it in a compressed state and in a stored state.

[0036] A lifting alarm mechanism is provided between the grounding rod 12 and the resistance wire 7. The lifting alarm mechanism includes a gear plate 14 installed on the front wall of the chassis body 1. The outer wall of the grounding rod 12 is provided with a tooth groove 23 that meshes with the gear plate 14. A cylindrical pin 15 is fixedly connected to the front wall of the gear plate 14. An insulating strip 16 is movably sleeved on the outer wall of the cylindrical pin 15, penetrating the inner bottom wall of the chassis body 1 and the inner top wall of the bottom cover 2. A fixed shaft is provided in the middle of the gear plate 14 and installed on the front inner wall of the chassis body 1. The insulating strip 16 is located below the fixed shaft, which can prevent the fixed shaft from affecting the movement of the insulating strip 16.

[0037] A limiting rod 19, which is fixedly connected to the inner walls of both sides of the bottom cover 2, is slidably inserted into the side wall of the insulating strip 16. A groove 17 matching the cylindrical pin 15 is opened on the outer wall of the insulating strip 16. A through groove 20 matching the insulating strip 16 is opened at the connection between the chassis body 1 and the bottom cover 2. A conductive rod 18, which slides and adheres to the surface of the resistance wire 7, is fixedly connected to the side wall of the insulating strip 16 near the ceramic cylinder 6. The wiring connections between the conductive rod 18, the battery, the buzzer 4, and the resistance wire 7 are as shown in the attached figure. Figure 3As shown, when the chassis 1 is placed vertically on the ground or table, the conductive rod 18 is in the middle of the resistance wire 7. At this time, the resistance of the resistance wire 7 in the circuit is at its maximum, and the current in the entire circuit is at its minimum. Therefore, the voltage across the buzzer 4 is at its minimum, and the buzzer 4 cannot make a sound. When someone lifts the chassis 1, the bottom cover 2 is off the ground. Then, the grounding rod 12 moves downward under the elastic force of the spring 13. Utilizing the meshing of the toothed groove 23 and the toothed disc 14, the toothed disc 14 rotates clockwise, driving the cylindrical pin 15 to move in a circular motion. Simultaneously, its sliding within the slide groove 17 moves the insulating strip 16 to the left, thereby causing the conductive rod 18 to move on the resistance wire 7. Moving the circuit reduces the resistance of the heating wire 7. As mentioned above, the voltage across the buzzer 4 increases, causing the buzzer 4 to emit an alarm sound in time, thus achieving the alarm effect. At the same time, the greater the lifting of the chassis body 1, the greater the downward movement of the grounding rod 12. The greater the distance that the gear plate 14 moves, the greater the distance that the insulating strip 16 and the conductive rod 18 move. The voltage across the buzzer 4 also increases, and the alarm sound of the buzzer 4 becomes louder and louder, thereby improving the alarm effect of the computer chassis and preventing serious damage. Therefore, the alarm sound can be emitted regardless of whether the chassis is lifted or moved, providing double protection and greatly improving the alarm effect of the device.

[0038] Anti-blocking mechanisms are provided between the grounding rod 12 and the multiple speaker holes 5 on both sides. The anti-blocking mechanism includes a gear 24 located on the rear side of the grounding rod 12 and meshing with the toothed groove 23. A rotating shaft 25 is fixedly installed through the middle of the gear 24 between the inner walls of both sides of the chassis body 1. Two fan blades 26 are symmetrically fixedly sleeved on the outer wall of the rotating shaft 25, which are respectively opposite to the multiple speaker holes 5 on both sides. When the chassis body 1 is lifted and the grounding rod 12 moves, it will drive the two fan blades 26 to rotate through the rotating shaft 25 by meshing with the gear 24, thereby blowing out the dust in each speaker hole 5, preventing the dust from blocking the speaker holes 5, so that the sound emitted from inside the chassis body 1 cannot be diffused to the outside of the chassis body 1 to the maximum extent, thus ensuring the sound emitted by the buzzer 4 when it alarms, and avoiding serious damage.

[0039] Furthermore, the front wall of the grounding rod 12 is vertically and equally spaced with multiple columns 27. The connection between the chassis body 1 and the bottom cover 2 is provided with sliding holes that match the grounding rod 12. The inner wall of the sliding holes is provided with through grooves 31 that match each column 27, allowing each column 27 to move up and down synchronously with the grounding rod 12.

[0040] Two vibration mechanisms are provided on the outer side of multiple columns 27. The vibration mechanism includes a notched ring 28 fixedly connected to the inner wall of the front side of the chassis body 1. Vibrating balls 29 are fixedly connected to both ends of the notched ring 28. Vibrating wings 30 are fixedly connected to the outer wall of the notched ring 28 and located between the two columns 27 on the same side. The vibrating wings 30 are thin sheets and can undergo a certain elastic deformation. Therefore, when the grounding rod 12 moves, it can also drive each column 27 to move vertically. During the movement, each column 27 will sequentially actuate each vibrating wing 30 and then quickly detach from the vibrating wing 30. Thus, the vibrating wing 30 will intermittently strike the two vibrating balls 29 on the same notched ring 28 under its own elasticity, thereby causing the notched ring 28 and the chassis body 1 to vibrate. This can shake off the dust in each speaker hole 5, further ensuring the unobstructed flow in each speaker hole 5, so that the sound emitted by the buzzer 4 can spread smoothly and quickly, ensuring the alarm effect of the device.

[0041] Furthermore, each column 27 and each vibrating ball 29 are made of iron. When each column 27 moves each vibrating fin 30, and when each vibrating fin 30 intermittently strikes each vibrating ball 29, a certain collision sound can be emitted through the rigid collision between the contact points of the two, which further improves the alarm effect of the device.

[0042] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
