Description

Technical Field

[0001] The invention relates to the technical field of computer hard disk fixing, in particular to a computer hard disk physical protection device based on impact absorption and a notebook computer. Background Art

[0002] During the operation of a laptop computer, the stability of the hard disk is extremely important. 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 laptop computer encounter impact or vibration, the shock-absorbing material can play a buffering role, absorb the force generated by external vibration, and then reduce the energy transmitted to the hard disk, thereby achieving shock absorption protection for the hard disk.

[0003] In daily use scenarios, this conventional shock absorption technology can cope with general vibrations and effectively reduce the risk of hard disk damage due to slight shaking. However, when the laptop is subjected to a large impact, such as accidentally falling, or in extreme cases where the hard disk is subjected to strong vibrations while working, the existing shock absorption technology exposes obvious shortcomings. Due to its limited ability to absorb and buffer energy, it is difficult to fully cope with high-intensity impacts, resulting in the shock absorption effect not meeting expectations, unable to provide sufficient protection for the hard disk, and exposing the hard disk to a higher risk of damage.

[0004] Chinese patent publication number CN107967045B provides a computer hard disk quick-install shock-absorbing bracket, including a bracket body, wherein the bracket body includes two horizontal plates arranged up and down and two vertical plates arranged left and right, the two horizontal plates and the two vertical plates surround to form a rectangular frame structure, the interior of the rectangular frame structure is a hard disk accommodating space, horizontal shock-absorbing mechanisms and vertical shock-absorbing mechanisms are arranged on the two horizontal plates, the hard disk is installed in the hard disk accommodating space, and the upper and lower sides of the hard disk are supported by rubber blocks arranged.

[0005] The shock-absorbing bracket uses a horizontal shock-absorbing mechanism and a vertical shock-absorbing mechanism to achieve a multi-directional shock-absorbing function, wherein the horizontal shock-absorbing mechanism is used to absorb lateral vibration and impact loads, and the vertical shock-absorbing mechanism is used to buffer vertical vibration and impact energy. However, when the external impact force borne by the shock-absorbing bracket exceeds the design load threshold of the horizontal shock-absorbing mechanism and the vertical shock-absorbing mechanism, the elastic deformation of the shock-absorbing mechanism will reach the limit, resulting in the inability to fully absorb the impact force. At this time, the impact energy that has not been attenuated will be transmitted to the hard disk through the 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] In view of the problems in the prior art, a computer hard disk physical protection device and a laptop computer based on impact absorption are provided. By elastically connecting an elastic connecting plate and a fixed frame, effective shock absorption of the hard disk under conventional impact loads is achieved. By cooperating with a positioning pin and a V-shaped guide groove, the number of shock absorption structural components is reduced, reliability is improved, and the subsequent maintenance and replacement costs are reduced. An overload protection mechanism is provided between the elastic connecting plate and the fixed connecting plate, so that when the load borne by the movable frame exceeds the elastic threshold between the elastic connecting plate and the fixed frame, the overload protection mechanism is triggered and cuts off the force transmission path between the elastic connecting plate and the fixed connecting plate, thereby being able to solve the problem of unattenuated impact energy being transmitted to the hard disk through the rigid connecting component, effectively solving the problem of mechanical damage or data loss of the hard disk caused by overload impact.

[0007] In order to solve the problems of the prior art, the present invention provides a computer hard disk physical protection device based on impact absorption, which is used for installing the hard disk in a computer hard disk installation compartment, including a fixed frame connected to the computer hard disk installation compartment and a movable frame connected to the hard disk, the movable frame having an elastic connecting plate and a fixed connecting plate, the elastic connecting plate and the fixed connecting plate are elastically connected, and the fixed connecting plate is rigidly connected to the hard disk; an overload protection mechanism is provided 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 overload protection mechanism is triggered and cuts off the force transmission path between the elastic connecting plate and the fixed connecting plate.

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

[0009] Preferably, a guide structure capable of extending along the displacement direction of the clamping block is provided on the fixed frame, a longitudinal elastic support member connected to the clamping block is provided on the fixed frame, the clamping block is slidably arranged on the guide structure, an elastic clamping element is arranged between the clamping block and the end of the guide structure, and the longitudinal elastic support member is used to absorb and buffer the load of the clamping block in a direction perpendicular to the fixed frame.

[0010] Preferably, the notch is a V-shaped guide groove, and the clamping block is provided with a positioning pin, which cooperates with the V-shaped guide groove. A pin cap is provided at the top of the positioning pin, and the pin cap forms a surface contact with the top of the V-shaped guide groove. When the elastic connecting plate is displaced in a direction perpendicular to the clamping force of the clamping block, the positioning pin slides along the inclined surface of the V-shaped guide 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 up multiple sets of springs in different directions, which reduces the number of parts and simplifies the overall structure. This not only reduces manufacturing costs, but also makes the assembly and maintenance of the equipment more convenient.

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

[0021] Reducing the number of elastic elements also reduces the risk of loss of buffering function due to spring failure. The reliability of a single locating pin and notch matching structure is relatively high as long as the quality and design of the locating pin and notch are guaranteed.

[0022] The simplified structure and reduced number of parts can reduce the cost of raw materials, processing and assembly during the production process. At the same time, due to the improved reliability, the cost of later maintenance and replacement may also be reduced, which has better cost-effectiveness overall. 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 the force transmission path between the elastic connecting plate and the fixed connecting plate will be cut off by breaking.

[0023] This design effectively prevents the unattenuated impact energy from being directly transmitted to the hard disk through the rigid connection components. In the traditional connection structure, when the impact energy exceeds the bearing capacity of the elastic component, the excess energy is often transmitted to the hard disk through the rigid connection part, which may cause damage to the mechanical structure inside the hard disk, such as disk scratches, head collisions, etc., and then lead to serious consequences such as data loss. By setting up an overload protection mechanism, the force transmission path is cut off in the case of overload, so that the hard disk and the external impact source are effectively isolated, which greatly reduces the risk of mechanical damage or data loss to the hard disk due to overload impact, and significantly improves the reliability and stability of hard disk storage devices in complex working environments.

DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1 and Figure 2 As 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.

[0028] 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.

[0029] 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, the elastic connection plate 21 and the fixing frame 1 are directly rigidly transmitted.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] Through this design, the protection device can provide comprehensive protection for the hard disk under different impact conditions. In the case of normal impact, the elastic connecting plate 21 plays a major role in shock absorption; in the case of overload impact, the overload protection mechanism 3 intervenes in time to prevent the unattenuated impact energy from being directly transmitted to the hard disk through the rigid connection components, thereby effectively preventing the hard disk from being mechanically damaged by overload impact, such as disk scratches, head collisions, or data loss, and 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.

[0034] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, an elastic connection component capable of forming an elastic connection is provided between the elastic connection plate 21 and the fixing frame 1, and the elastic connection component includes two clamping blocks 231 symmetrically arranged on the fixing frame 1 and capable of elastically clamping the elastic connection plate 21, and notches 211 are provided on the two side edges of the elastic connection plate 21, and the notches 211 are used to form positioning and cooperation with the clamping blocks 231.

[0035] When installing the elastic connection plate 21, the notches 211 on both sides thereof are aligned with the clamping blocks 231 on the fixing frame 1, and a certain external force is applied to make the clamping blocks 231 fit into the notches 211. In this process, the clamping blocks 231 will generate an elastic clamping force on the elastic connection plate 21, thereby realizing an elastic connection between the elastic connection plate 21 and the fixing frame 1.

[0036] The elastic connection mode of the notch 211 and the clamping block 231 can not only effectively realize the connection between the elastic connection plate 21 and the fixing frame 1, but also can make use of the restraining effect of the clamping block 231 and the notch 211 to make the elastic connection plate 21 move freely within a certain range when subjected to external force impact, thereby giving full play to the shock absorbing function of the elastic connection. At the same time, the positioning and matching relationship between the notch 211 and the clamping block 231 can also ensure the accurate position of the elastic connection plate 21 on the fixing frame 1, thereby improving the reliability and stability of the entire connection structure.

[0037] like Figure 8 and Fig.10 As shown, the fixing frame 1 is provided with a guide structure 11 which can extend along the displacement direction of the clamping block 231, and the fixing frame 1 is provided with a longitudinal elastic support member 12 connected to the clamping block 231. The clamping block 231 is slidably arranged on the guide structure 11, and an elastic clamping element 232 is arranged between the clamping block 231 and the end of the guide structure 11. The longitudinal elastic support member 12 is used to absorb and buffer the load of the clamping block 231 along the direction perpendicular to the fixing frame 1.

[0038] The guide structure 11 is provided with a guide rod 112 extending along its length direction, and the elastic clamping element 232 is sleeved on the guide rod 112 .

[0039] 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 coil 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 a 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 related components from damage.

[0040] 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 guide structure 11. The elastic clamping element 232 generally has a high elastic coefficient and a good fatigue life, and can continuously provide a stable clamping force during long-term use.

[0041] like Figure 4 and Fig. 9 As shown, the notch 211 is a V-shaped guide groove, and the clamping block 231 is provided with a positioning pin 2311, which cooperates with the V-shaped guide groove. The top of the positioning pin 2311 is provided with a pin cap, which forms a surface contact with the top of the V-shaped guide groove. When the elastic connecting plate 21 is displaced in a direction perpendicular to the clamping force direction of the clamping block 231, the positioning pin 2311 slides along the inclined surface of the V-shaped guide groove.

[0042] like Figure 6 As shown, when the elastic connecting plate 21 is displaced vertically relative to the fixing frame 1, because the positioning pin 2311 is elastically abutted against 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 is displaced horizontally relative to the fixing frame, it is necessary to overcome the elastic force of the positioning pin 2311 on the inclined surface of the notch 211. Therefore, when the positioning pin 2311 clamps the notch 211, the impact force of the elastic connecting plate 21 on the fixing frame 1 in the horizontal and vertical directions can be buffered.

[0043] At the same time, when the elastic connecting plate 21 generates any 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.

[0044] Compared with the existing devices that can only perform multi-directional buffering through multiple sets of springs in different directions, it has the following advantages: it does not need to set multiple sets of springs in different directions, reduces the number of parts, and simplifies the overall structure. This not only reduces the manufacturing cost, but also makes the assembly and maintenance of the equipment more convenient.

[0045] Since there is no need to arrange multiple sets of springs, it has more advantages in space utilization. For some hard disk installation compartments with limited space, this structure can make more effective use of space and meet the needs of equipment miniaturization.

[0046] Reducing the number of springs also reduces the risk of loss of buffering function due to spring failure. The single positioning pin 2311 and notch 211 matching structure has relatively high reliability as long as the quality and design of the positioning pin 2311 and notch 211 are guaranteed.

[0047] The simplified structure and reduced number of parts can reduce the cost of raw materials, processing and assembly during the production process. At the same time, due to the improved reliability, the subsequent maintenance and replacement costs may also be reduced, which has better cost-effectiveness overall.

[0048] When the elastic connecting plate 21 is displaced in a direction perpendicular to the clamping force of the clamping block 231 during operation, the positioning pin 2311 will slide along the inclined surface of the V-shaped guide groove. The inclined surface of the V-shaped guide groove has a specific inclination angle. In the process of the positioning pin 2311 sliding along the inclined surface, the inclined surface of the V-shaped guide groove plays a dual role of guidance 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 accurate and controllable; on the other hand, the presence of the inclined surface makes the positioning pin 2311 gradually compress or stretch the elastic clamping element 232 associated with it during the sliding process, thereby achieving 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.

[0049] The matching structural design of the V-shaped guide 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 is displaced, thereby 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.

[0050] like Figure 8 As shown, the positioning pin 2311 is composed of a lower pin body fixed to the clamping block 231 and an upper pin body cooperating with the V-shaped guide groove, and 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 a preset threshold, the shear weakening groove 2312 breaks to achieve mechanical separation of the upper pin body and the lower pin body.

[0051] The upper pin body and the lower pin body are connected through the shear weakened groove 2312, and they jointly assume the functions of positioning and guiding. When the elastic connecting plate 21 is subjected to abnormal external impact or other factors that cause the load on the upper pin body to exceed the preset threshold, the stress at the shear weakened groove 2312 will quickly concentrate and exceed the shear strength limit of its material. At this time, the shear weakened groove 2312 will break, thereby achieving mechanical separation of the upper pin body and the lower pin body. This design mechanism can, in extreme cases, promptly cut off the force transmission path that may cause damage to the elastic connecting plate 21 and the hard disk, thereby playing a role in overload protection. In this way, damage to the elastic connecting plate 21, the clamping block 231 or other related components caused by excessive load is effectively avoided, ensuring the safety and reliability of the entire connection structure under complex working conditions, while also providing convenience for equipment maintenance and troubleshooting.

[0052] like Figure 4 , Figure 7 and Fig.10 As shown, the longitudinal elastic support member 12 is composed of an outer elastic arm 121 extending upward from the fixing frame 1 and an inner elastic arm 122 connected to the top of the outer elastic arm 121, and an elastic deformation space is formed between the outer elastic arm 121 and the inner elastic arm 122; the end of the guide 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.

[0053] 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 member 12. When subjected to a load perpendicular to the direction of the fixing frame 1, the outer elastic arm 121 and the inner elastic arm 122 will cooperate to elastically deform, 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.

[0054] The end of the guide structure 11 is connected to the inner elastic arm 122, and this connection mode forms a whole between the guide structure 11 and the longitudinal elastic support member 12. 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 guide structure 11 can effectively guide the movement of the clamping block 231, and the longitudinal elastic support member 12 can timely absorb and buffer the vertical load generated by the movement of the clamping block 231.

[0055] like Figure 3 As shown, the overload protection mechanism 3 includes a lower connecting head 32 connected to the fixed connecting plate 22 and an upper connecting head 31 connected to the elastic connecting plate 21, and shear safety pieces 33 are arranged equidistantly between the upper connecting head 31 and the lower connecting head 32; the middle diameter of the shear safety piece 33 is smaller than the diameter at both ends thereof 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.

[0056] Several shear safety pieces 33 are evenly spaced 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 achieving the overload protection function. The diameter of the middle part of the shear safety piece 33 is smaller than the diameter of the two ends. This special geometric shape forms a stress concentration area in the middle part. When bearing a load, the stress will be concentrated in this area, thereby reducing the shear strength of this part.

[0057] Under normal working conditions, the shear safety sheet 33 can withstand loads within a certain range and effectively transfer the force between the upper connector 31 and the lower connector 32 to ensure the stability of the connection between the elastic connecting plate 21 and the fixed connecting plate 22. However, when the load borne by the movable frame exceeds the preset threshold, the stress acting on the shear safety sheet 33 also increases. Once the stress reaches and exceeds the shear strength limit of the material in the stress concentration area in the middle of the shear safety sheet 33, the area will break.

[0058] The breaking of the shear safety sheet 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 transmitted to key components such as the hard disk through the 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 equipment under complex working conditions.

[0059] like Figure 4 As shown, the fixing frame 1 is provided with a guide groove extending along the displacement direction of the clamping block 231, the guide groove forms a guide structure 11, the clamping block 231 is slidably arranged in the sliding groove, and the longitudinal elastic support members 12 are arranged at both ends of the guide groove.

[0060] The matching clearance between the clamping block 231 and the guide groove ensures that the clamping block 231 can slide smoothly in the guide groove, and prevents shaking and instability caused by too large a clearance. The clamping block 231 can be smoothly displaced according to a predetermined trajectory under the constraint of the guide groove, thereby achieving accurate clamping and positioning of the elastic connecting plate 21.

[0061] The longitudinal elastic support members 12 are respectively arranged at both ends of the guide 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 guide groove and is subjected to an external force in the vertical direction, the longitudinal elastic support member 12 will undergo corresponding elastic deformation, converting the impact energy into its 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 continue to work stably in a complex working environment.

[0062] like Fig. 9 As shown, the fixed connecting plates 22 are two symmetrical plates symmetrically arranged on both sides of the elastic connecting plate 21. Each fixed connecting plate 22 is provided with a mounting interface 221 extending along the length direction of the hard disk. The mounting interface 221 is provided with a fastening screw 222, and the fastening screw 222 is connected to the threaded hole of the hard disk.

[0063] The fixed connecting plate 22 is composed of two symmetrical plates, which are symmetrically arranged on both sides of the elastic connecting plate 21. This symmetrical arrangement design not only ensures the balanced stability of the structure in terms of mechanics, but also can evenly disperse the external force borne by the hard disk to avoid local stress concentration caused by uneven force, and is also convenient for operation and maintenance during installation and disassembly.

[0064] The existence of the installation interface 221 provides an accurate positioning and connection basis for the installation of the hard disk, so that the hard disk can be accurately connected to the fixed connection plate 22.

[0065] The installation interface 221 is provided with a fastening screw 222 as a key part 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. This connection method uses the self-locking characteristics of the thread to generate friction during the tightening process, thereby firmly fixing the hard disk on the fixed connection plate 22. During the installation process, by accurately controlling the tightening torque of the fastening screw 222, the stability of the hard disk installation can be ensured, and damage to the hard disk or the fixed connection plate 22 caused by over-tightening can be avoided.
