Description

Technical Field

[0001] The present invention relates to the field of hard disk protection, and in particular to a hard disk box control method and system with an adaptive transmission protocol. Background Art

[0002] An adaptive transmission protocol hard drive enclosure refers to a device that is equipped with intelligent identification and automatic adaptation of transmission protocol technology to accommodate and protect the hard drive, and convert its interface into a universal interface for easy connection to other devices.

[0003] In the prior art, as a device that protects the hard disk and realizes data transmission, the impact resistance of the hard disk case is crucial to the stability of the hard disk and data security. The hard disk case generally includes a shell composed of a metal frame and a buffer device. The buffer device generally includes a silicone hanging rope. The hard disk is suspended in the shell by the elastic silicone hanging rope to avoid hard contact, so that when an impact occurs, the elastic structure buffers the displacement and reduces the direct force on the hard disk. The lower the elastic coefficient of the silicone hanging rope, the better the buffering effect.

[0004] When the hard drive case is subjected to high-intensity impact, the silicone rope is easily stretched, causing the hard drive to collide with the inner wall of the hard drive case, thereby causing damage to the hard drive. Summary of the Invention

[0005] In order to improve the convenience of using a hard disk enclosure and reduce the collision between the hard disk and the inner wall of the hard disk enclosure, the present invention provides a hard disk enclosure control method and system with an adaptive transmission protocol.

[0006] In a first aspect, the present invention provides a hard disk enclosure control method for an adaptive transmission protocol, which adopts the following technical solution:

[0007] A method for controlling a hard disk enclosure with an adaptive transmission protocol, comprising:

[0008] Step 100: collecting the impact velocity of the hard disk enclosure;

[0009] Step 101: determining an impact force in response to the impact velocity;

[0010] Step 102: determining an impact coefficient in response to the impact force and a preset buffer distance;

[0011] Step 103: determining an adjustment length in response to the impact coefficient and a preset buffer coefficient;

[0012] Step 104: Control the preset buffer device to expand or contract the buffer rope according to the adjustment length, and define the impact coefficient as the buffer coefficient.

[0013] By adopting the above technical solution, the moving speed of the hard disk case is collected in real time, so as to estimate the impact force that the hard disk case will receive when it is collided at the current speed, and then select the appropriate elastic coefficient according to the impact force, and adjust the buffer coefficient of the buffer rope by adjusting the length of the buffer rope, thereby reducing the collision between the hard disk and the inner wall of the hard disk case and improving the convenience of using the hard disk case.

[0014] Optionally, also include:

[0015] Step 105: When the impact coefficient is greater than a preset adjustment threshold, determining a threshold difference in response to the impact coefficient and the preset adjustment threshold;

[0016] Step 106: determining a softening temperature in response to the threshold difference, and collecting hard disk temperature;

[0017] Step 107: determining a heating temperature in response to the softening temperature and the hard disk temperature;

[0018] Step 108: Control the preset softening device to soften the buffer rope according to the heating temperature.

[0019] By adopting the above technical solution, when the impact force applied to the hard disk is too large, the buffer rope may be easily subjected to excessive tension instantaneously, thereby causing damage to the buffer rope. The buffer rope can be softened by heating the buffer rope through the softening device, thereby reducing damage to the buffer rope.

[0020] Optionally, a buffer enhancement method is further included, and the buffer enhancement method includes:

[0021] Step 200: When the impact coefficient is greater than a preset adjustment threshold, determining an impact direction in response to the impact velocity;

[0022] Step 201: determining a blocking position in response to the impact direction;

[0023] Step 202: Determine the inner length of the box in response to the blocking position;

[0024] Step 203: determining a blocking stroke in response to the blocking position and the impact direction;

[0025] Step 204: Control the preset blocking device to move to the blocking position according to the blocking stroke and release the buffer rope according to the length in the box.

[0026] By adopting the above technical solution, when the impact force on the hard disk is too large, the buffer rope pre-installed in the hard disk box is insufficient to provide buffering tension. At this time, the blocking device moves in the circumferential direction of the hard disk to release the buffer rope in the direction of the impact of the hard disk to form a buffer belt, thereby increasing the tension that the hard disk box can provide and improving the convenience of using the hard disk box.

[0027] Optionally, the buffer enhancement method further includes:

[0028] Step 205: When the impact coefficient is greater than a preset adjustment threshold, determining a force difference in response to the impact force and a preset buffer force;

[0029] Step 206: determining a deformation length in response to the force difference;

[0030] Step 207: determining a blocking length in response to the deformation length and the inner length of the box;

[0031] Step 208: Update the blocking position in response to the blocking length and impact direction.

[0032] By adopting the above technical solution, there is a limit to the length that a buffer rope per unit length can be stretched, that is, there is a limit to the tension that a buffer rope per unit length can provide. When the impact force on the hard disk is too large, the blocking device moves in the hard disk box, so that the buffer rope released by the blocking device is pressed by the hard disk and stretched, thereby pre-tightening the hard disk without reducing the upper limit of the tension that the buffer rope can provide, so as to reduce the tension on the buffer rope when the hard disk box is suddenly impacted, thereby reducing damage to the buffer rope.

[0033] Optionally, the buffer enhancement method further includes:

[0034] Step 209: determining a deformation threshold in response to the inner length of the box;

[0035] Step 210: When the force difference is greater than the deformation threshold, determining a blocking difference in response to the force difference and the deformation threshold;

[0036] Step 211: determining a winding length in response to the blocking difference;

[0037] Step 212: determining the number of winding turns in response to the winding length;

[0038] Step 213: determining a winding stroke in response to the number of winding turns;

[0039] Step 214: Control the preset blocking device to wind the hard disk according to the winding stroke and release the buffer rope according to the winding length.

[0040] By adopting the above technical solution, when the tension provided by the buffer rope is insufficient, the blocking device is rotated in the circumferential direction of the hard disk, thereby wrapping the buffer rope around the circumferential direction of the hard disk, thereby enhancing the upper limit of the tension provided by the buffer rope, thereby reducing the situation where the buffering effect of the hard disk box is low due to insufficient tension.

[0041] Optionally, the buffer enhancement method further includes:

[0042] Step 215: updating the deformation threshold in response to the winding length;

[0043] Step 216: When the force difference is not greater than the deformation threshold, determining the deformation force in response to the impact direction;

[0044] Step 217: When the deformation force is less than the force difference, determining the position of the pull rod in response to the impact direction;

[0045] Step 218: Control the preset pull rod device to move to the pull rod position, and control the preset blocking device to wind the hard disk according to the winding stroke.

[0046] By adopting the above technical solution, there is a limit to the distance that the hard disk can buffer in the hard disk box. When the hard disk is displaced to the limit in the hard disk box and is still not enough to offset the impact force it receives, the position of the pull rod device is adjusted and the buffer rope is passed around the pull rod device and the hard disk at the same time through the blocking device, thereby increasing the deformation of the buffer rope when the hard disk is impacted and moved, thereby increasing the tension that the buffer rope can provide.

[0047] Optionally, the buffer enhancement method further includes:

[0048] Step 219: Determine a deformation length in response to the impact force and a preset buffer coefficient;

[0049] Step 220: Determine the number of turns around the rod in response to the position and deformation length of the rod;

[0050] Step 221: When the number of turns around the rod is not greater than the number of blocked turns, the difference between the number of blocked turns and the number of turns around the rod is calculated and defined as the turn difference;

[0051] Step 222: determining a follow-up stroke in response to the turn number difference and the winding stroke;

[0052] Step 223: determining a follow-up time in response to the winding stroke and the number of turns around the rod;

[0053] Step 224: Control the preset blocking device to wind the hard disk according to the winding stroke, and control the preset pull rod device to move along with the blocking device according to the following stroke at the following moment.

[0054] By adopting the above technical solution, the length of deformation required for the buffer rope to provide a pulling force equivalent to the impact force exerted on the hard disk is calculated, and the number of turns of the buffer rope wrapped around the pull rod device is selected so that the buffer rope can just deform to the corresponding length, thereby reducing the situation where the buffer effect of the buffer rope is reduced due to too many turns wrapped around the pull rod device.

[0055] Optionally, an anti-shock method is further included, and the anti-shock method includes:

[0056] Step 300: determining a buffer gas volume in response to the impact force;

[0057] Step 301: determining an impacted position in response to the impact direction;

[0058] Step 302: determining an airbag number in response to the impact position and a preset airbag partition;

[0059] Step 303: Control the preset airbag device to inflate the airbag with the airbag number according to the buffer gas volume.

[0060] By adopting the above technical solution, when the speed of the hard disk box is too high, the position where the hard disk box is impacted is estimated according to the direction of movement of the hard disk box, thereby controlling the inflation of the airbag device at the corresponding position, and then reducing the damage to the hard disk box when it collides through the airbag.

[0061] Optionally, the anti-shock method further includes:

[0062] Step 304: determining a retracted length in response to the buffer gas volume, and determining an airbag thickness in response to the buffer gas volume;

[0063] Step 305: Determine the number of airbags in response to the airbag thickness;

[0064] Step 306: updating the airbag number in response to the number of airbags and the impacted position;

[0065] Step 307: Control the preset airbag device to inflate the airbag with the airbag number according to the buffer gas volume, and the preset airbag device retracts the airbag according to the retraction length.

[0066] By adopting the above technical solution, after the airbag is inflated, the airbag device is controlled to retract the airbag, thereby reducing the capacity of the airbag to make the airbag swell, thereby reducing the situation where the air in the airbag is squeezed and deflected to the other side when the airbag is hit.

[0067] In a second aspect, the present application provides a hard disk enclosure control system with an adaptive transmission protocol, which adopts the following technical solutions:

[0068] A hard disk enclosure control system with an adaptive transmission protocol, comprising:

[0069] Acquisition module, used to collect impact velocity and hard disk temperature;

[0070] A memory for storing any one of the above-mentioned methods for controlling a hard disk enclosure using an adaptive transmission protocol;

[0071] The processor can load and execute the program in the memory.

[0072] By adopting the above technical solution, the moving speed of the hard disk case is collected in real time, so as to estimate the impact force that the hard disk case will receive when it is collided at the current speed, and then select the appropriate elastic coefficient according to the impact force, and adjust the buffer coefficient of the buffer rope by adjusting the length of the buffer rope, thereby reducing the collision between the hard disk and the inner wall of the hard disk case and improving the convenience of using the hard disk case.

[0073] In summary, this application includes at least one of the following beneficial technical effects:

[0074] 1. The system collects the moving speed of the hard drive enclosure in real time to estimate the impact force it would experience if it were to collide at the current speed. It then selects an appropriate elastic coefficient based on the impact force and adjusts the buffer rope's length to adjust its buffer coefficient. This reduces collisions between the hard drive and the enclosure's inner wall, improving the enclosure's ease of use.

[0075] 2. When the impact force on the hard drive is too great, the buffer rope is easily subjected to excessive tension, which can damage the buffer rope. The softening device heats the buffer rope to soften it, thereby reducing damage to the buffer rope.

[0076] 3. When the impact force on the hard disk is too large, the buffer rope pre-installed in the hard disk box is insufficient to provide buffering tension. At this time, the blocking device moves in the circumferential direction of the hard disk to release the buffer rope in the direction of the impact of the hard disk to form a buffer belt, thereby increasing the tension that the hard disk box can provide and improving the convenience of using the hard disk box.

[0086] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0087] An embodiment of the present application discloses a hard disk box control method and system with adaptive transmission protocol, including a protocol intelligent detection module, a protocol intelligent switching module, a power management module and a heat dissipation module. The protocol intelligent detection module quickly scans and identifies the transmission interface type (such as USB, SATA, Thunderbolt, etc.) of the external device through a built-in protocol identification chip or software algorithm, and thus evaluates the optimal transmission protocol in the current environment based on factors such as device performance and bandwidth requirements; the protocol intelligent switching module caches historical connection records and predicts the protocols that may be used in the future based on a machine learning algorithm, and prepares resources in advance; the protocol intelligent switching module is responsible for seamless switching between different transmission protocols to ensure the continuity and stability of data transmission; the power management module is responsible for monitoring and managing the power supply of the hard disk box to ensure the stability and energy saving effect of the system; the heat dissipation module is responsible for the heat dissipation management of the hard disk box to ensure that the system can still work normally in a high temperature environment.

[0088] Reference Figure 1 , a hard disk box control method for adaptive transmission protocol, comprising:

[0089] Step 100: Collect the impact velocity of the hard disk enclosure.

[0090] Impact velocity refers to the moving speed of the hard disk box. The impact velocity can be collected by using a radar speed measuring device fixed on the hard disk box. The method of collecting the impact velocity is selected by the staff according to the actual situation and will not be elaborated here.

[0091] Step 101: Determine the impact force in response to the impact velocity.

[0092] Impact force refers to the maximum impact force that the hard disk enclosure receives when it is suddenly stopped by an obstruction. The calculation method of impact force is common knowledge among people in this field and will not be elaborated here.

[0093] Step 102: Determine an impact coefficient in response to the impact force and a preset buffer distance.

[0094] The buffer rope refers to the rope used to suspend and fix the hard drive in the hard drive box. The buffer distance refers to the distance value of the buffer for the suspended hard drive in the hard drive box. The buffer rope and buffer distance are selected by the staff according to actual conditions and will not be elaborated here.

[0095] The impact coefficient refers to the elastic coefficient value required for the buffer rope to provide a tensile force equivalent to the impact force. Generally, the quotient of the impact force and the buffer distance is calculated, and then the quotient is divided by 2 as the impact coefficient.

[0096] Step 103: Determine an adjustment length in response to the impact coefficient and a preset buffer coefficient.

[0097] The buffer coefficient refers to the current elastic coefficient of the buffer rope. The buffer coefficient can be selected by the staff according to the actual situation and will not be detailed here. The adjustment length refers to the length of the buffer rope required to adjust from the buffer coefficient to the impact coefficient. The impact relationship table can be used to query the stretch length corresponding to the impact coefficient and the buffer coefficient respectively, and then calculate the difference in stretch length as the adjustment length. The stretch length refers to the length the buffer rope needs to be stretched to reach the corresponding elastic coefficient. The elastic coefficient of the buffer rope generally increases with the degree of deformation. The impact relationship table is a data table that records different elastic coefficients and their corresponding stretch lengths.

[0098] Step 104: Control the preset buffer device to expand or contract the buffer rope according to the adjustment length, and define the impact coefficient as the buffer coefficient.

[0099] The moving speed of the hard drive case is collected in real time to estimate the impact force that the hard drive case will receive when it is hit at the current speed. The appropriate elastic coefficient is then selected based on the impact force. The buffer coefficient of the buffer rope is adjusted by adjusting the length of the buffer rope, thereby reducing the collision between the hard drive and the inner wall of the hard drive case and improving the convenience of using the hard drive case.

[0100] Reference Figure 2 , a hard disk box control method for adaptive transmission protocol, further comprising:

[0101] Step 105: When the impact coefficient is greater than a preset adjustment threshold, a threshold difference is determined in response to the impact coefficient and the preset adjustment threshold.

[0102] As the length of the buffer rope approaches its elastic limit, it becomes more susceptible to irreversible damage. The adjustment threshold is the minimum elastic coefficient that easily damages the buffer rope. The adjustment threshold is selected by staff based on actual conditions and is not detailed here. If the impact coefficient is greater than the adjustment threshold, the buffer rope is overstretched. The threshold difference is the difference between the impact coefficient and the adjustment threshold, which indicates the stretch of the buffer rope.

[0103] Step 106: Determine the softening temperature in response to the threshold difference, and collect the hard disk temperature.

[0104] The physical properties of the buffer rope are easily affected by temperature, and generally show the characteristics of softening at high temperature and hardening at low temperature. The softening temperature refers to the temperature value at which the buffer rope is softened to reduce damage to the buffer rope. The larger the threshold difference, the greater the degree of stretching of the buffer rope, and the higher the softening temperature required. The softening temperature can be obtained from the softening data table, which is a data table that records different threshold differences and their corresponding softening temperatures.

[0105] The hard disk temperature refers to the real-time temperature value of the hard disk. The hard disk temperature can be collected by a temperature sensor fixed in the hard disk box. The hard disk temperature collection method is selected by the staff based on the actual situation and will not be detailed here.

[0106] Step 107: Determine a heating temperature in response to the softening temperature and the hard disk temperature.

[0107] The softening device is a device installed inside the hard drive enclosure to soften the buffer rope. The softening device is selected by the staff based on actual conditions and is not detailed here. The heating temperature refers to the temperature at which the softening device softens the buffer rope. The heating temperature is generally calculated as the difference between the softening temperature and the hard drive temperature. The calculation method for the heating temperature is selected by the staff based on actual conditions and is not detailed here.

[0108] Step 108: Control the preset softening device to soften the buffer rope according to the heating temperature.

[0109] When the impact force on the hard disk is too great, the buffer rope may be easily subjected to excessive tension at the moment, which may cause damage to the buffer rope. The buffer rope can be softened by heating the buffer rope through a softening device, thereby reducing damage to the buffer rope.

[0110] Reference Figure 3 , buffer enhancement methods include:

[0111] Step 200: When the impact coefficient is greater than a preset adjustment threshold, determining the impact direction in response to the impact velocity.

[0112] The impact direction refers to the angle value of the hard disk box movement. The impact direction can be determined by the impact speed detected by the radar speed measuring device. The method for determining the impact direction is common knowledge among people in this field and will not be elaborated here.

[0113] Step 201: Determine a blocking position in response to the impact direction.

[0114] The blocking device is a device used to deploy a buffer rope in the direction of the hard drive's impact to form a buffer zone. It typically utilizes a pair of motor-driven rollers. The hard drive enclosure includes a spiral guide rail for the blocking device to move around the hard drive. The blocking device is selected by the operator based on practical needs and is not described in detail here. The blocking position refers to the location of the blocking device when the buffer zone is formed in the direction of the hard drive's impact. This refers to the intersection of a plane perpendicular to the impact direction and directly contacting the hard drive's edge with the guide rail for the blocking device's movement. Determining the blocking position is common knowledge in the field and is not described here.

[0115] Step 202: Determine the inner length of the box in response to the blocking position.

[0116] The length inside the box refers to the length of the buffer rope between the blocking devices, that is, the distance between the blocking positions. The method for determining the length inside the box is common knowledge among people in this field and will not be elaborated here.

[0117] Step 203: Determine a blocking stroke in response to the blocking position and the impact direction.

[0118] The blocking stroke refers to the route that the blocking devices move to the blocking positions to form a buffer zone in the impact direction. The method for determining the blocking stroke is common knowledge among people in this field and will not be elaborated here.

[0119] Step 204: Control the preset blocking device to move to the blocking position according to the blocking stroke and release the buffer rope according to the length in the box.

[0120] When the impact force on the hard disk is too large, the buffer rope pre-installed in the hard disk case is insufficient to provide buffering tension. At this time, the blocking device moves in the circumferential direction of the hard disk to release the buffer rope in the direction of the impact of the hard disk to form a buffer belt, thereby increasing the tension that the hard disk case can provide and improving the convenience of using the hard disk case.

[0121] Reference Figure 4 , the buffer enhancement method further includes:

[0122] Step 205: When the impact coefficient is greater than a preset adjustment threshold, a force difference is determined in response to the impact force and a preset buffering force.

[0123] Buffering force refers to the maximum impact force that a buffer rope can buffer, which is the product of the buffering distance and the buffering coefficient. The buffering force is selected by the staff based on actual conditions and is not detailed here. The force difference is a value used to demonstrate the buffering effect of the pre-set buffer rope. It is generally calculated as the difference between the impact force and the buffering force.

[0124] Step 206: Determine a deformation length in response to the force difference.

[0125] The deformation length refers to the length of deformation required for the buffer rope to provide the tension of the force difference, that is, the quotient of the force difference and the buffer coefficient.

[0126] Step 207: Determine the blocking length in response to the deformation length and the inner length of the box.

[0127] The blocking length refers to the length required for the buffer zone formed by the blocking device to provide the pulling force of the force difference, that is, the sum of the deformation length and the length inside the box.

[0128] Step 208: Update the blocking position in response to the blocking length and impact direction.

[0129] There is a limit to the length to which a buffer rope per unit length can be stretched, that is, there is a limit to the tension that a buffer rope per unit length can provide. When the impact force on the hard disk is too large, the blocking device moves inside the hard disk case, so that the buffer rope released by the blocking device is pressed by the hard disk and stretched, thereby pre-tightening the hard disk without reducing the upper limit of the tension that the buffer rope can provide, so as to reduce the tension on the buffer rope when the hard disk case is suddenly impacted, thereby reducing damage to the buffer rope.

[0130] Reference Figure 5 , the buffer enhancement method further includes:

[0131] Step 209: Determine a deformation threshold in response to the inner length of the box.

[0132] The deformation threshold refers to the maximum tension value that can be provided when the deformation of the buffer rope between the blocking devices reaches the limit. The deformation threshold corresponding to the length inside the box can be queried from the limit data table. The limit data table refers to a data table that records different box lengths and their corresponding deformation thresholds.

[0133] Step 210: When the force difference is greater than the deformation threshold, determine a blocking difference in response to the force difference and the deformation threshold.

[0134] A force difference greater than the deformation threshold indicates that the buffer ropes between the arresting devices cannot provide sufficient tension, that is, the buffering effect of the buffer ropes between the arresting devices is insufficient. The arresting difference refers to a numerical value used to show the degree of insufficient buffering effect of the buffer ropes between the arresting devices. Generally, the difference between the force difference and the deformation threshold is calculated as the arresting difference.

[0135] Step 211: Determine the winding length in response to the blockage difference.

[0136] The winding length refers to the shortest buffer rope length required to provide the tension of the interception difference. The winding length corresponding to the interception difference can be found in the limit data table.

[0137] Step 212: Determine the number of winding turns in response to the winding length.

[0138] The number of winding turns refers to the minimum number of turns that a buffer rope of the same winding length can wrap around the hard drive. Generally, the difference between the winding length and the hard drive circumference is calculated as the number of winding turns. The hard drive circumference refers to the circumference value of the hard drive in the impact direction. The hard drive circumference can be input in advance by the staff. When the number of winding turns is not an integer, it will be rounded up.

[0139] Step 213: Determine the winding stroke in response to the number of winding turns.

[0140] The winding stroke refers to the route that the blocking device takes to wind the buffer rope onto the hard disk according to the number of winding turns. The method for determining the winding stroke is common knowledge among people in this field and will not be elaborated here.

[0141] Step 214: Control the preset blocking device to wind the hard disk according to the winding stroke and release the buffer rope according to the winding length.

[0142] When the tension provided by the buffer rope is insufficient, the blocking device is rotated in the circumferential direction of the hard disk, thereby wrapping the buffer rope around the circumferential direction of the hard disk, thereby increasing the upper limit of the tension provided by the buffer rope, thereby reducing the situation where the buffering effect of the hard disk box is low due to insufficient tension.

[0143] Reference Figure 6 , the buffer enhancement method further includes:

[0144] Step 215: Update the deformation threshold in response to the winding length.

[0145] When the blocking device releases the buffer rope according to the winding length, the maximum tension that the buffer rope can provide increases. At this time, the sum of the winding length and the length inside the box is first calculated as the actual length, and then the deformation threshold corresponding to the actual length is queried from the limit data table.

[0146] Step 216: When the force difference is not greater than the deformation threshold, determine the deformation force in response to the impact direction.

[0147] Deformation force refers to the maximum tension that the buffer rope can provide after the hard disk is displaced to the limit in the hard disk enclosure, that is, the maximum tension that the buffer rope can provide when the blocking devices are all located in the direction opposite to the impact direction of the hard disk. The moving distance that the hard disk can move in the impact direction in the hard disk enclosure can be read first and multiplied by 2 as the maximum distance, and then the product of the maximum distance and the buffer coefficient is calculated as the deformation force, where the moving distance can be input in advance by the staff.

[0148] Step 217: When the deformation force is less than the force difference, determine the position of the pull rod in response to the impact direction.

[0149] The pull rod device refers to a device around which the buffer rope is wound to increase its deformation. The pull rod device is located between the blocking device and the hard drive and can move circumferentially around the hard drive. The pull rod device is selected by the staff based on actual conditions and is not described in detail here. If the deformation force is less than the force difference, it means that the maximum tension value that can be provided by adjusting the position of the blocking device is insufficient to provide buffering for the hard drive. The pull rod position is the position of the pull rod device around which the buffer rope is wound. The position opposite to the impact direction of the hard drive is generally used as the pull rod position. The method for determining the pull rod position is common knowledge in this field and is not described in detail here.

[0150] Step 218: Control the preset pull rod device to move to the pull rod position, and control the preset blocking device to wind the hard disk according to the winding stroke.

[0151] There is a limit to the distance that the hard drive can buffer in the hard drive case. When the hard drive moves to the limit in the hard drive case and is still not enough to offset the impact force it receives, the position of the pull rod device is adjusted and the buffer rope is passed around the pull rod device and the hard drive at the same time through the blocking device, thereby increasing the deformation of the buffer rope when the hard drive moves under impact, and then increasing the tension that the buffer rope can provide.

[0152] Reference Figure 7 , the buffer enhancement method further includes:

[0153] Step 220: Determine the number of turns around the rod in response to the position of the rod and the deformation length.

[0154] The number of turns around the rod refers to the minimum number of turns required for the buffer rope to provide sufficient tension. The difference between the deformation length and the maximum distance can be calculated as the first length required for deformation and stretching. The circumferential length required for the buffer rope to wrap around the pull rod device and the hard disk when the hard disk has no displacement is then determined by the pull rod position. The second length of the buffer rope stretched after wrapping around the pull rod device is calculated from the circumferential length, and then the sum of the buffer distance multiplied by 2 and the second length is calculated as the third length that can be stretched to the maximum after wrapping around the pull rod device. Finally, the quotient of the first length and the third length is calculated as the number of turns around the rod. If the number of turns around the rod is not an integer, it is rounded up.

[0155] Step 221: When the number of turns around the pole is not greater than the number of blocking turns, the difference between the number of blocking turns and the number of turns around the pole is calculated and defined as the turn difference.

[0156] The number of turns around the pole is not greater than the number of blocking turns, which means that the buffer rope is sufficient to turn around the pull rod. The difference in turns refers to the number of turns that do not need to be wound.

[0157] Step 222: Determine the follow-up stroke in response to the turn number difference and the winding stroke.

[0158] The follow-up stroke refers to the route along which the pull rod device moves together with the blocking device so as not to be entangled by the buffer rope released by the blocking device. The method for determining the follow-up stroke is common knowledge among people in this field and will not be elaborated here.

[0159] Step 223: Determine the follow-up time in response to the winding stroke and the number of turns around the rod.

[0160] The following moment is the moment when the blocking device wraps the rod around the number of times. The pull rod device is located between the blocking device and the hard disk. When the blocking device moves around the hard disk to wrap the buffer rope around the hard disk, the winding rope is simultaneously wrapped around the pull rod device. The following moment is the time required for the blocking device to wrap the rod around the hard disk. The method for determining the following moment is common knowledge among people in this field and will not be elaborated here.

[0161] Step 224: Control the preset blocking device to wind the hard disk according to the winding stroke, and control the preset pull rod device to move along with the blocking device according to the following stroke at the following moment.

[0162] The length of deformation required for the buffer rope to provide a tensile force equivalent to the impact force exerted on the hard disk is calculated, and the number of turns of the buffer rope wrapped around the pull rod device is selected so that the buffer rope can just deform to the corresponding length, thereby reducing the situation where the buffer rope's buffering effect is reduced due to too many turns wrapped around the pull rod device.

[0163] Reference Figure 8 , anti-shock methods include:

[0164] Step 300: Determine the buffer gas volume in response to the impact force.

[0165] The airbag device refers to a device installed outside the hard disk case for cushioning. The airbag device includes a motor for expanding and contracting the airbag to adjust the airbag capacity. There are multiple airbag devices evenly arranged on the hard disk case, and the maximum capacity of each airbag device is equal. The airbag device automatically empties the internal air to reduce the volume of the airbag after each use. The airbag device is selected by the staff according to actual conditions and will not be elaborated here.

[0166] The cushioning air volume refers to the volume of air inflated in the airbag device. The greater the impact force, the larger the cushioning air volume is required to provide sufficient cushioning effect. The cushioning air volume can be obtained from the air volume relationship table, which is a data table that records different impact forces and their corresponding cushioning air volumes.

[0167] Step 301: Determine an impacted position in response to the impact direction.

[0168] The impact position refers to the first point of contact when the hard disk enclosure is hit. The method for determining the impact position is common knowledge among those skilled in the art and will not be elaborated here.

[0169] Step 302: Determine an airbag number in response to the impact position and the preset airbag partition.

[0170] The airbag number refers to the number used to distinguish the airbag device. The airbag zone refers to the range covered by the airbag device corresponding to the pre-set airbag number. The airbag number corresponding to the impact position can be queried from the airbag zone.

[0171] Step 303: Control the preset airbag device to inflate the airbag with the airbag number according to the buffer gas volume.

[0172] When the speed of the hard drive case is too high, the position where the hard drive case is impacted is estimated according to the direction of its movement, so as to control the inflation of the airbag device at the corresponding position, thereby reducing the damage to the hard drive case during a collision through the airbag.

[0173] Reference Figure 9 , anti-shock methods also include:

[0174] Step 304: Determine the retracted length in response to the buffer gas volume, and determine the airbag thickness in response to the buffer gas volume.

[0175] The retraction length refers to the length value of the airbag inflated by retracting the airbag through the motor in the airbag device. The retraction length can be queried from the retraction relationship table. The retraction relationship table refers to a data table that records different buffer gas volumes and their corresponding retraction lengths.

[0176] The airbag thickness refers to the distance value at the thickest part of the airbag device. When the motor inside the airbag device retracts the airbag, the coverage area of ​​the airbag device remains unchanged while the thickness decreases. The airbag thickness can be determined by calculating the quotient of the buffer gas volume and the coverage area.

[0177] Step 305: Determine the number of airbags in response to the airbag thickness.

[0178] The number of airbags refers to the number of airbags required. When the thickness of the airbag is low, it is easy for the hard drive to be impacted by the airbag device. The number of airbags can be queried from the quantity data table. The quantity data table refers to a data table that records different airbag thickness ranges and their corresponding airbag quantities.

[0179] Step 306: Update the airbag number in response to the number of airbags and the impact position.

[0180] When the thickness of the airbag device is relatively low, the airbag device closest to the impacted position is selected at one time according to the number of airbags and inflated to enhance the cushioning effect of the airbag device.

[0181] Step 307: Control the preset airbag device to inflate the airbag with the airbag number according to the buffer gas volume, and the preset airbag device retracts the airbag according to the retraction length.

[0182] When the airbag is inflated, the airbag device is controlled to retract the airbag, thereby reducing the capacity of the airbag to allow the airbag to expand, thereby reducing the situation where the air in the airbag is squeezed and deflected to the other side when the airbag is hit.
