Physical protection device for computer hard drive based on shock absorption and laptop computer

Abstract

The present invention relates to the technical field of computer hard disk fixation, specifically to a physical protection device for computer hard disks and a notebook computer based on shock absorption, which are applied to installing a hard disk in a computer hard disk installation compartment. It consists of a fixing frame connected to the installation compartment and a movable frame connected to the hard disk. The movable frame includes an elastic connecting plate and a fixed connecting plate. The former is elastically connected to the fixing frame, and the latter is rigidly connected to the hard disk. An overload protection mechanism is provided between the elastic connecting plate and the fixed connecting plate. Normally, the elastic connection between the elastic connecting plate and the fixing frame can effectively shock-absorb the hard disk under normal impacts. By matching the positioning pins with the notches, the shock-absorbing structural components are reduced. When the load borne by the movable frame exceeds the elastic threshold, the overload protection mechanism is triggered to cut off the force transmission path between the elastic connecting plate and the fixed connecting plate, preventing the unattenuated shock energy from being transmitted to the hard disk through rigid components, effectively avoiding mechanical damage or data loss of the hard disk caused by overload shocks, and improving the safety and stability of the hard disk.

Description

Technical Field

[0001] The present invention relates to the technical field of computer hard disk fixation, and particularly to a physical protection device for a computer hard disk and a notebook computer based on shock absorption. Background Art

[0002] During the operation of a notebook computer, the stability of the hard disk is crucial. To ensure the safety of the hard disk in various environments, hard disk shock absorption technology has emerged. The traditional hard disk shock absorption method mainly uses shock-absorbing materials to surround the hard disk in all directions. Its working principle is that when the peripheral devices of the notebook computer encounter impact or vibration, the shock-absorbing materials can play a buffering role, absorb the force generated by the external vibration, and then reduce the energy transmitted to the hard disk, realizing the shock absorption protection of the hard disk.

[0003] In daily use scenarios, this conventional shock absorption technology can handle general levels of vibration and effectively reduce the risk of damage to the hard disk due to slight shaking. However, when the notebook computer is subjected to a large impact force, such as accidentally falling, or in the extreme case where the hard disk encounters strong vibration during operation, the existing shock absorption technology reveals obvious deficiencies. Due to its limited ability to absorb and buffer energy, it is difficult to fully handle high-intensity impacts, resulting in the shock absorption effect not meeting expectations, being unable to provide sufficient protection for the hard disk, and making the hard disk face a high risk of damage.

[0004] Chinese Patent Publication No. CN107967045B provides a computer hard disk quick-install shock absorption bracket, including a bracket body. The bracket body includes two horizontally arranged cross plates and two vertically arranged vertical plates. The two cross plates and the two vertical plates enclose a rectangular frame structure. The interior of this rectangular frame structure is a hard disk accommodation space. Horizontal shock absorption mechanisms and vertical shock absorption mechanisms are provided on both cross plates. The hard disk is installed in the hard disk accommodation space, and the upper and lower sides of the hard disk are supported by rubber blocks provided.

[0005] This shock absorption bracket uses horizontal shock absorption mechanisms and vertical shock absorption mechanisms to achieve multi-directional shock absorption functions. Among them, the horizontal shock absorption mechanism is used to absorb lateral vibrations and impact loads, and the vertical shock absorption mechanism is used to buffer vibrations and impact energy in the vertical direction. However, when the external impact force borne by the shock absorption bracket exceeds the design load threshold of the horizontal shock absorption mechanism and the vertical shock absorption mechanism, the elastic deformation amount of the shock absorption mechanism will reach the limit, resulting in the impact force not being completely absorbed. At this time, the unattenuated impact energy will be conducted to the hard disk through rigid connection components, causing mechanical damage to the precision components inside the hard disk, and then leading to data loss or hard disk failure. Summary of the Invention

[0006] Aiming at the problems of the existing technology, a physical protection device for a computer hard disk based on shock absorption and a laptop computer are provided. By elastically connecting an elastic connecting plate and a fixing frame, effective shock absorption for the hard disk under normal shock loads is achieved. Through the cooperation of a positioning pin and a V-shaped guiding groove, the number of shock-absorbing structural components is reduced, the reliability is improved, and the later maintenance and replacement costs are reduced at the same time. An overload protection mechanism is arranged between the elastic connecting plate and the fixed connecting plate, so that when the load borne by the movable frame exceeds the elastic threshold value between the elastic connecting plate and the fixing frame, the overload protection mechanism is triggered and the force transmission path between the elastic connecting plate and the fixed connecting plate is cut off, thereby being able to solve the problem that the unattenuated shock energy will be conducted to the hard disk through the rigid connecting components, effectively solving the problems of mechanical damage or data loss of the hard disk caused by overload shock.

[0007] To solve the problems of the existing technology, the present invention provides a physical protection device for a computer hard disk based on shock absorption, which is applied to installing a hard disk in a computer hard disk installation bin. The device includes a fixing frame connected to the computer hard disk installation bin and a movable frame connected to the hard disk. The movable frame has an elastic connecting plate and a fixed connecting plate. The elastic connecting plate is elastically connected to the fixing frame, and the fixed connecting plate is rigidly connected to the hard disk. An overload protection mechanism is arranged between the elastic connecting plate and the fixed connecting plate. When the load borne by the movable frame exceeds the elastic threshold value between the elastic connecting plate and the fixing frame, the overload protection mechanism is triggered and the force transmission path between the elastic connecting plate and the fixed connecting plate is cut off.

[0008] Preferably, an elastic connection component capable of forming an elastic connection is arranged between the elastic connecting plate and the fixing frame. The elastic connection component includes two clamping blocks symmetrically arranged on the fixing frame and capable of elastically clamping the elastic connecting plate. Notches are provided at both side edges of the elastic connecting plate, and the notches are used for positioning and cooperating with the clamping blocks.

[0009] Preferably, a guiding structure capable of extending along the displacement direction of the clamping block is arranged on the fixing frame. A longitudinal elastic support member connected to the clamping block is arranged on the fixing frame. The clamping block is slidably arranged on the guiding structure, and an elastic clamping element is arranged between the clamping block and the end of the guiding structure. The longitudinal elastic support member is used for absorbing and buffering the load of the clamping block in the direction perpendicular to the fixing frame.

[0010] Preferably, the notch is a V-shaped guiding groove, a positioning pin is arranged on the clamping block, the positioning pin is in contact with the V-shaped guiding groove in a matching manner, a pin cap is arranged at the top of the positioning pin, and the pin cap forms a surface contact with the top of the V-shaped guiding groove. When the elastic connecting plate generates a displacement in the direction perpendicular to the clamping force direction of the clamping block, the positioning pin slides along the inclined surface of the V-shaped guiding groove.

[0011] Preferably, the positioning pin is composed of a lower pin body fixed to the clamping block and an upper pin body cooperating with the V-shaped guide groove, and a shear weakening groove is provided between the upper pin body and the lower pin body; when the load borne by the upper pin body exceeds a preset threshold, the shear weakening groove breaks to achieve mechanical separation of the upper pin body and the lower pin body.

[0012] Preferably, the longitudinal elastic support member is composed of an outer elastic arm extending upward from a fixed frame and an inner elastic arm connected to the top end of the outer elastic arm, and an elastic deformation space is formed between the outer elastic arm and the inner elastic arm; the end of the guide structure is connected to the inner elastic arm, and the elastic clamping element is arranged between the clamping block and the inner elastic arm.

[0013] Preferably, the overload protection mechanism includes a lower connecting head connected to the fixed connecting plate and an upper connecting head connected to the elastic connecting plate, and shear safety plates are equidistantly arranged between the upper connecting head and the lower connecting head; the middle diameter of the shear safety plate is smaller than the diameter at both ends to form a stress concentration area; when the load borne by the shear safety plate exceeds a preset threshold, the stress concentration area breaks.

[0014] Preferably, a guide groove extending along the displacement direction of the clamping block is provided on the fixing frame, the guide groove forms a guide structure, the clamping block is slidably arranged in the sliding groove, and longitudinal elastic support members are arranged at both ends of the guide groove.

[0015] Preferably, the fixed connecting plates are two symmetrical plates symmetrically arranged on both sides of the elastic connecting plate, each of which is provided with a mounting interface extending along the length direction of the hard disk, and the mounting interface is provided with a fastening screw, which is connected to the threaded hole of the hard disk.

[0016] A laptop computer, characterized in that it comprises a physical protection device for a computer hard disk based on impact absorption.

[0017] Compared with the prior art, the present application has the following beneficial effects: by using an elastic connection method to connect the elastic connection plate with the fixing frame, the present application can effectively absorb and buffer the impact energy when a conventional impact load acts on the hard disk storage device, thereby achieving reliable shock absorption protection for the hard disk. Specifically, when impacted, the elastic connection structure between the elastic connection plate and the fixing frame will undergo elastic deformation, converting the impact energy into its own elastic potential energy, thereby reducing the direct effect of the impact on the hard disk, and ensuring that the hard disk can still operate stably under a certain degree of impact environment.

[0018] Through the elastic cooperation between the positioning pin and the slot and the need for the positioning pin to overcome the elastic force when subjected to axial force, the impact force exerted on the elastic connecting plate in any direction can be buffered. Compared with the existing device that can only perform buffering in multiple directions through multiple groups of springs in different directions, it has the following advantages.

[0019] There is no need to set multiple groups of springs in different directions, which reduces the number of parts and simplifies the overall structure. This not only reduces the manufacturing cost but also may make the assembly and maintenance of the equipment more convenient.

[0020] Since there is no need to arrange multiple groups of springs, it has an advantage in space utilization. For some hard disk installation bins with limited space, this structure can make more effective use of space and meet the requirements of equipment miniaturization.

[0021] Reducing the number of elastic elements also reduces the risk of the loss of the buffering function due to spring failure. For the single positioning pin and notch matching structure, as long as the quality and design of the positioning pin and notch are reasonable, its reliability is relatively high.

[0022] With the simplified structure and reduced number of parts, the raw material cost, processing cost and assembly cost can be reduced during the production process. At the same time, due to the improved reliability, the later maintenance and replacement costs may also be reduced, and overall it has better cost - effectiveness. At the same time, in order to cope with extreme situations beyond the normal elastic working range of the elastic connecting plate, an overload protection mechanism is set between the elastic connecting plate and the fixed connecting plate. When the load borne by the movable frame exceeds the elastic threshold between the elastic connecting plate and the fixed frame, the elastic connection structure between the elastic connecting plate and the fixed frame can no longer completely absorb the impact energy through its own elastic deformation. At this time, the overload protection mechanism will be quickly triggered and cut off the force transmission path between the elastic connecting plate and the fixed connecting plate by breaking.

[0023] This design effectively avoids the unattenuated impact energy from being directly conducted to the hard disk through rigid connection components. In the traditional connection structure, when the impact energy exceeds the bearing capacity of the elastic components, the excess energy often passes through the rigid connection part to the hard disk, which may cause damage to the internal mechanical structure of the hard disk, such as disk scratch, head collision, etc., and then lead to serious consequences such as data loss. By setting the overload protection mechanism to cut off the force transmission path in case of overload, an effective isolation is formed between the hard disk and the external impact source, greatly reducing the risk of mechanical damage or data loss of the hard disk due to overload impact, and significantly improving the reliability and stability of the hard disk storage device in a complex working environment.

Detailed implementation manners

[0035] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0036] As shown in Figure 1 and Figure 2As shown, the present application provides a computer hard disk physical protection device based on impact absorption, which is used to install the hard disk in the computer hard disk installation compartment, including a fixed frame 1 connected to the computer hard disk installation compartment and a movable frame connected to the hard disk, the movable frame has an elastic connecting plate 21 and a fixed connecting plate 22, the elastic connecting plate 21 is elastically connected to the fixed frame 1, and the fixed connecting plate 22 is rigidly connected to the hard disk; an overload protection mechanism 3 is arranged between the elastic connecting plate 21 and the fixed connecting plate 22, when the load borne by the movable frame exceeds the elastic threshold between the elastic connecting plate 21 and the fixed frame 1, the overload protection mechanism 3 is triggered and cuts off the force transmission path between the elastic connecting plate 21 and the fixed connecting plate 22.

[0037] It should be noted that “elastic connection” means that the connection structure between the elastic connection plate 21 and the fixing frame 1 can be deformed after being subjected to force, and return to the original state after the external force disappears.

[0038] The "elastic threshold" refers to the maximum stress or strain value that the connection structure between the elastic connection plate 21 and the fixing frame 1 can withstand within the elastic deformation range. When the stress or strain caused by external force exceeds this threshold, rigid force is directly transmitted between the elastic connection plate 21 and the fixing frame 1.

[0039] The fixing frame 1 serves as the basic supporting component of the entire protection device. It is tightly connected to the computer hard disk installation compartment through specific connection methods such as bolt fastening and snap connection, ensuring a stable position and posture during computer operation, providing a reliable installation reference for the hard disk.

[0040] When the hard disk is subjected to conventional impact loads, the elastic connection structure between the elastic connection plate 21 and the fixing frame 1 will deform accordingly, converting the impact energy into its own elastic potential energy, thereby effectively absorbing and buffering the impact, reducing the direct effect of the impact on the hard disk, and ensuring that the hard disk can still work normally under a certain degree of impact environment.

[0041] When the load borne by the movable frame exceeds the elastic threshold between the elastic connecting plate 21 and the fixed frame 1, the elastic connection structure between the elastic connecting plate 21 and the fixed frame 1 can no longer completely absorb the impact energy through its own elastic deformation. At this time, the overload protection mechanism 3 will be quickly triggered, and its triggering mechanism may include mechanical triggering such as lever principle, shear pin, hydraulic triggering or electronic triggering. Once triggered, the overload protection mechanism 3 will cut off the force transmission path between the elastic connecting plate 21 and the fixed connecting plate 22 through specific actions such as tripping, breaking or locking.

[0042] With this design, the protection device can provide comprehensive protection for the hard disk under different impact conditions. Under normal impact conditions, the elastic connecting plate 21 plays a major shock-absorbing role; while in the case of overload impact, the overload protection mechanism 3 intervenes in time to prevent the unattenuated impact energy from being directly conducted to the hard disk through the rigid connecting components, thus effectively preventing mechanical damages such as disk scratching and head collision or data loss of the hard disk caused by overload impact, significantly improving the reliability and stability of the hard disk in complex working environments, extending the service life of the hard disk, and providing a strong guarantee for the security of computer data storage.

[0043] As Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, an elastic connection assembly capable of forming an elastic connection is provided between the elastic connecting plate 21 and the fixing frame 1. The elastic connection assembly includes two clamping blocks 231 symmetrically arranged on the fixing frame 1 and capable of elastically clamping the elastic connecting plate 21. Notches 211 are provided at both side edges of the elastic connecting plate 21, and the notches 211 are used to form positioning and cooperation with the clamping blocks 231.

[0044] When installing the elastic connecting plate 21, align the notches 211 on both sides thereof with the clamping blocks 231 on the fixing frame 1, and by applying a certain external force, make the clamping blocks 231 embed into the notches 211. During this process, the clamping blocks 231 will generate an elastic clamping force on the elastic connecting plate 21, thereby realizing the elastic connection between the elastic connecting plate 21 and the fixing frame 1.

[0045] Through the elastic connection method of the cooperation between the notches 211 and the clamping blocks 231, not only can the connection between the elastic connecting plate 21 and the fixing frame 1 be effectively realized, but also when subjected to external force impact, by the constraint of the clamping blocks 231 and the notches 211, the elastic connecting plate 21 can move freely within a certain range, thus giving full play to the shock-absorbing function of the elastic connection. At the same time, the positioning and cooperation relationship between the notches 211 and the clamping blocks 231 can also ensure the accurate position of the elastic connecting plate 21 on the fixing frame 1, improving the reliability and stability of the entire connection structure.

[0046] As Figure 8 and Figure 10 shown, a guiding structure 11 capable of extending along the displacement direction of the clamping blocks 231 is provided on the fixing frame 1, a longitudinal elastic support member 12 connected to the clamping blocks 231 is provided on the fixing frame 1, the clamping blocks 231 are slidably arranged on the guiding structure 11, and an elastic clamping element 232 is provided between the clamping blocks 231 and the end of the guiding structure 11. The longitudinal elastic support member 12 is used to absorb and buffer the load of the clamping blocks 231 along the direction perpendicular to the fixing frame 1.

[0047] The guiding structure 11 is provided with a guiding rod 112 extending along its length direction, and the elastic clamping element 232 is sleeved on the guiding rod 112.

[0048] The longitudinal elastic support member 12 is usually made of a material with a suitable elastic modulus and good elastic recovery performance, such as a helical spring made of spring steel or an elastomer made of rubber. Its main function is to absorb and buffer the load borne by the clamping block 231 in the direction perpendicular to the fixing frame 1. When an external impact force acts on the clamping block 231, the longitudinal elastic support member 12 will undergo elastic deformation, converting the impact energy into its own elastic potential energy, thereby effectively reducing the impact on the entire connection structure and protecting the relevant components from damage.

[0049] In order to ensure that the clamping block 231 always maintains a stable elastic clamping force on the elastic connecting plate 21 during the sliding process, an elastic clamping element 232 is provided between the clamping block 231 and the end of the guiding structure 11. The elastic clamping element 232 usually has a high elastic coefficient and good fatigue life, and can continuously provide a stable clamping force during long-term use.

[0050] As Figure 4 and Figure 9 shown, the notch 211 is a V-shaped guiding groove, and the clamping block 231 is provided with a positioning pin 2311. The positioning pin 2311 is in contact with the V-shaped guiding groove in a matching manner. A pin cap is provided at the top of the positioning pin 2311, and the pin cap forms a surface contact with the top of the V-shaped guiding groove. When the elastic connecting plate 21 generates a displacement along the direction perpendicular to the clamping force of the clamping block 231, the positioning pin 2311 slides along the inclined surface of the V-shaped guiding groove.

[0051] As Figure 6 shown, when the elastic connecting plate 21 generates a displacement in the vertical direction relative to the fixing frame 1, since the positioning pin 2311 is elastically abutted in the notch 211, it is necessary to overcome the elastic force of the positioning pin 2311 on the notch 211. And when the elastic connecting plate 21 generates a displacement in the horizontal direction relative to the fixing frame, it is necessary to overcome the elastic force generated by the positioning pin 2311 on the inclined surface of the notch 211. Therefore, when the positioning pin 2311 clamps the notch 211, it can buffer the impact force in the horizontal and vertical directions of the elastic connecting plate 21 relative to the fixing frame 1.

[0052] At the same time, when the elastic connecting plate 21 generates an arbitrary displacement in the horizontal direction relative to the fixing frame 1, the positioning pin 2311 and the notch 211 are always elastically matched, so as to buffer the impact force in any horizontal direction.

[0053] Compared with the existing devices that require multiple sets of springs in different directions to perform buffering in multiple directions, it has the following advantages: There is no need to set multiple sets of springs in different directions, which reduces the number of parts and simplifies the overall structure. This not only reduces the manufacturing cost but also may make the assembly and maintenance of the equipment more convenient.

[0054] Since there is no need to arrange multiple sets of springs, it has more advantages in space utilization. For some hard disk installation bins with limited space, this structure can make more effective use of space and meet the requirements of equipment miniaturization.

[0055] Reducing the number of springs also reduces the risk of the buffering function being lost due to spring failure. The single positioning pin 2311 and the notch 211 matching structure, as long as the quality and design of the positioning pin 2311 and the notch 211 are reasonable, its reliability is relatively high.

[0056] The structure is simplified and the number of parts is reduced, which can reduce the raw material cost, processing cost and assembly cost during the production process. At the same time, due to the improvement of reliability, the later maintenance and replacement costs may also be reduced, and overall it has better cost-effectiveness.

[0057] When the elastic connecting plate 21 generates displacement in the process along the direction perpendicular to the clamping force direction of the clamping block 231 during operation, the positioning pin 2311 will slide along the inclined plane of the V-shaped guiding groove. The inclined plane of the V-shaped guiding groove has a specific inclination angle. During the process of the positioning pin 2311 sliding along the inclined plane, the inclined plane of the V-shaped guiding groove plays a dual role of guiding and buffering. On the one hand, it guides the positioning pin 2311 to move along a predetermined trajectory to ensure that the displacement direction of the elastic connecting plate 21 is accurately controllable; on the other hand, the existence of the inclined plane causes the positioning pin 2311 to gradually compress or stretch the related elastic clamping element 232 during the sliding process, thereby realizing the buffering and shock absorption of the displacement of the elastic connecting plate 21 and reducing the impact of the impact force generated by the displacement on the entire connection structure.

[0058] This matching structure design of the V-shaped guiding groove and the positioning pin 2311 not only realizes the precise positioning and reliable connection between the elastic connecting plate 21 and the clamping block 231, but also can effectively guide and buffer the movement of the elastic connecting plate 21 when it generates displacement, improving the stability, reliability and service life of the entire connection structure, and meeting the strict requirements for elastic connection and displacement control under complex working conditions.

[0059] As Figure 8 shown, the positioning pin 2311 is composed of a lower pin body fixed to the clamping block 231 and an upper pin body that cooperates with the V-shaped guiding groove. A shear weakening groove 2312 is provided between the upper pin body and the lower pin body; when the load borne by the upper pin body exceeds the preset threshold, the shear weakening groove 2312 breaks to realize the mechanical separation of the upper pin body and the lower pin body.

[0060] The upper pin body and the lower pin body are kept connected through the shear weakening groove 2312 and jointly undertake the functions of positioning and guiding. When the elastic connecting plate 21 is subjected to abnormal external impacts or other factors, causing the load borne by the upper pin body to exceed the preset threshold, the stress at the shear weakening groove 2312 will rapidly concentrate and exceed the shear strength limit of its material. At this time, the shear weakening groove 2312 will break, thus realizing the mechanical separation of the upper pin body and the lower pin body. This design mechanism can, in extreme cases, timely cut off the force transmission path that may damage the elastic connecting plate 21 and the hard disk, playing a role of overload protection. In this way, it effectively avoids the damage of the elastic connecting plate 21, the clamping block 231 or other related components caused by excessive loads, ensures the safety and reliability of the entire connection structure under complex working conditions, and also provides convenience for the maintenance and troubleshooting of the equipment.

[0061] As Figure 4 , Figure 7 and Figure 10 shown, the longitudinal elastic support 12 is composed of an outer elastic arm 121 extending upward from the fixed frame 1 and an inner elastic arm 122 connected to the top end of the outer elastic arm 121. An elastic deformation space is formed between the outer elastic arm 121 and the inner elastic arm 122; the end of the guiding structure 11 is connected to the inner elastic arm 122, and the elastic clamping element 232 is arranged between the clamping block 231 and the inner elastic arm 122.

[0062] A specific elastic deformation space is formed between the inner elastic arm 122 and the outer elastic arm 121, and the size and shape of this space have an important influence on the elastic performance of the longitudinal elastic support 12. When subjected to a load perpendicular to the direction of the fixed frame 1, the outer elastic arm 121 and the inner elastic arm 122 will cooperate to undergo elastic deformation, and absorb and buffer the energy brought by the load through the change of the elastic deformation space, thereby reducing the impact on the entire connection structure.

[0063] The end of the guiding structure 11 is connected to the inner elastic arm 122, and this connection method makes the guiding structure 11 and the longitudinal elastic support 12 form an integral body. The design of the connection part fully considers the force transmission path and the stability of the structure, ensuring that during the movement of the clamping block 231, the guiding structure 11 can effectively guide the movement of the clamping block 231, and at the same time the longitudinal elastic support 12 can timely absorb and buffer the vertical load generated by the movement of the clamping block 231.

[0064] As Figure 3As shown in the figure, the overload protection mechanism 3 includes a lower connector 32 connected to the fixed connection plate 22 and an upper connector 31 connected to the elastic connection plate 21. Shear safety pieces 33 are arranged at equal intervals between the upper connector 31 and the lower connector 32; the middle diameter of the shear safety piece 33 is smaller than the diameters at both ends to form a stress concentration area; when the load borne by the shear safety piece 33 exceeds a preset threshold, the stress concentration area breaks.

[0065] A number of shear safety pieces 33 are equally distributed between the upper connector 31 and the lower connector 32. These shear safety pieces 33 play a core role in the overload protection mechanism 3, and their unique structural design is the key to realizing the overload protection function. The middle part of the shear safety piece 33 has a smaller diameter than the diameters at both ends, and this special geometric shape makes a stress concentration area formed in the middle part. When bearing a load, stress will concentrate in this area, thereby reducing the shear strength of this part.

[0066] Under normal working conditions, the shear safety piece 33 can bear a certain range of loads and effectively transfer the force between the upper connector 31 and the lower connector 32, ensuring the stable connection between the elastic connection plate 21 and the fixed connection plate 22. However, when the load borne by the movable frame exceeds the preset threshold, the stress acting on the shear safety piece 33 also increases accordingly. Once the stress reaches and exceeds the material shear strength limit of the stress concentration area in the middle of the shear safety piece 33, this area will break.

[0067] The breakage of the shear safety piece 33 can quickly cut off the force transmission path between the upper connector 31 and the lower connector 32, thereby preventing the unattenuated impact energy from being conducted to key components such as the hard disk through rigid connection components, effectively preventing problems such as mechanical damage or data loss caused by overload impact. Through this design, the overload protection mechanism 3 can be triggered in time when the system faces an overload risk, providing reliable safety protection for the entire system and ensuring the stable operation of the device under complex working conditions.

[0068] As Figure 4 As shown in the figure, a guiding groove extending along the displacement direction of the clamping block 231 is provided on the fixed frame 1, and the guiding groove forms a guiding structure 11. The clamping block 231 is slidably arranged in the sliding groove, and longitudinal elastic supports 12 are arranged at both ends of the guiding groove.

[0069] The fitting clearance between the clamping block 231 and the guiding groove not only ensures that the clamping block 231 can slide smoothly in the guiding groove, but also prevents shaking and instability caused by too large a clearance. The clamping block 231 can displace smoothly along a predetermined trajectory under the constraint of the guiding groove, so as to realize the precise clamping and positioning of the elastic connection plate 21.

[0070] The longitudinal elastic support members 12 are respectively arranged at both ends of the guiding groove. The main function of the longitudinal elastic support members 12 is to absorb and buffer the load borne by the clamping block 231 in the direction perpendicular to the fixing frame 1. When the clamping block 231 slides in the guiding groove and is subjected to an external force in the vertical direction, the longitudinal elastic support members 12 will undergo corresponding elastic deformation, converting the impact energy into their own elastic potential energy, thereby reducing the impact force on the fixing frame 1 and other components. This design not only protects the entire structure from damage, but also improves the stability and reliability of the system, ensuring that the clamping block 231 can work continuously and stably under complex working conditions.

[0071] As Figure 9 shown, the fixed connection plates 22 are two symmetric plate bodies symmetrically arranged on both sides of the elastic connection plate 21. Each fixed connection plate 22 is provided with an installation interface 221 extending along the length direction of the hard disk. A fastening screw 222 is arranged on the installation interface 221, and the fastening screw 222 is connected to the threaded hole of the hard disk.

[0072] The fixed connection plates 22 are composed of two symmetric plate bodies and are symmetrically arranged on both sides of the elastic connection plate 21. This symmetric arrangement design not only ensures the balance and stability of the structure mechanically, can evenly disperse the external force borne by the hard disk, and avoid local stress concentration caused by uneven stress, but also facilitates operation and maintenance during the installation and disassembly process.

[0073] The existence of the installation interface 221 provides an accurate positioning and connection basis for the installation of the hard disk, enabling the hard disk to be accurately docked with the fixed connection plate 22.

[0074] On the installation interface 221, a fastening screw 222 is provided as a key component for connecting the hard disk and the fixed connection plate 22. The fastening screw 222 is threadedly connected to the preset threaded hole on the hard disk.
