Description

Technical Field

[0001] The invention relates to the technical field of component transportation reliability detection, and more specifically to a rotating edge drop test device and a control method. Background Art

[0002] The road transportation test of the server is the core part of its reliability test. The rotating edge drop test is a method to simulate the real situation of the server being rotated, hit, dropped, etc. during transportation. It can effectively test the impact resistance and reliability of the server during transportation.

[0003] At present, the rotating edge drop test is performed by tying a strap on the raised side of the server cabinet, lifting the strap by a crane to place a wooden block on the raised side, and then tying the strap on the side opposite to the raised side. After the crane lifts the strap to a certain height, the strap is loosened to allow the server cabinet to fall freely, and then the rotating edge drop test on the side opposite to the raised side can be performed. In this way, the operations of tying and loosening the strap are all performed manually, and the height of the crane lifting is visually determined by the crane operator. Human interference will cause large errors, resulting in poor accuracy and effectiveness of the test.

DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] The core of the present invention is to provide a rotating edge drop test device, which does not require close manual operation, ensures the safety and reliability of the test, and intelligently controls the control elements to avoid human errors, simplify the test process, save manpower and material resources, and improve the test efficiency and test accuracy and effectiveness. Another core of the present invention is to provide a control method for the above-mentioned rotating edge drop test device.

[0061] The rotating edge drop test device provided by the present invention includes a test frame 2, a side frame 3, a stopper assembly 5, a lifting assembly 4 and a control element. Please refer to Figure 1 .

[0062] Please refer to Figure 7 At least two side frames 3 are provided on the test frame 2 for supporting the sides of the object to be tested 1. The object to be tested 1 may be a cabinet, a server, a pallet, a carton, a shipping box or other component that needs to undergo a rotating edge drop test.

[0063] The side frame 3 is arranged inside the test frame 2 or the side frame 3 is arranged on the test frame 2 , and the test frame 2 provides a space for lifting and setting the side frame 3 .

[0064] When conducting the test, first determine which side of the object to be tested 1 is to be subjected to the rotation drop test. The side here is the target side. In the initial state, the side frames all support the side of the object to be tested 1. When conducting the test, the control component controls the stopper components 5 corresponding to the target side and the side adjacent to the target side to operate to unlock the corresponding side frame 3. After the side frame 3 is unlocked, it will freely fall onto the lifting component 4 under the action of the object to be tested and its own gravity to complete the rotation edge drop test of the target side.

[0065] After completing the rotating edge drop test on the target side, the control component controls the lifting component 4 to drive the fallen side frame 3 on its upper side to rise and reset to the initial state, and then the control component controls the stop component to lock the risen and reset side frame 3. At this time, the object to be tested 1 is also reset to the initial state, and then the lifting component 4 is controlled to descend to the initial state. At this time, the experimental device is reset as a whole, and then the rotating edge drop test on other sides can be carried out.

[0066] Take the cabinet as an example. Figure 8 As shown, the side edges of the cabinet are specifically side A, side B, side C, and side D. Next, the support relationship and drop test of at least two side frames 3 corresponding to the cabinet are introduced with side A as the target side. On the premise that side A is the target side, side B and side C are two sides adjacent to side A of the target side, and side D is the side opposite to side A of the target side.

[0067] In a specific embodiment, two side frames 3 are arranged on the test frame 2, and the lifting and lowering of the two side frames 3 do not interfere with each other. One side frame 3 is used to support the A side, the B side, and the C side, and the other side frame 3 is used to support the D side. The target side A side is the side that needs to fall. In this case, when performing the rotating edge drop test, a side frame 3 corresponding to the supporting side A side, the B side, and the C side falls under the action of gravity, and the side frame 3 corresponding to the D side remains in the original position, so that the rotating edge drop test of the target side A side can be achieved.

[0068] In another specific embodiment, three side frames 3 are arranged on the test frame 2, wherein one side frame 3 supports side A, another side frame 3 supports side B and side C at the same time, and another side frame 3 supports side D. The target side A is the side that needs to fall. In this case, when performing the rotating edge drop test, the two side frames 3 corresponding to the supporting sides A, B, and C are made to fall under the action of gravity, and the side frame 3 corresponding to the side D remains in the original position, so that the rotating edge drop test of the target side A can be achieved. If the rotating edge drop test of other sides is required, it is only necessary to control the other two corresponding side frames 3 to fall. For example, if the rotating edge drop test of side D is performed, the side frame 3 supporting side D and the side frames 3 supporting sides B and C can be made to fall under the action of gravity.

[0069] On the basis of setting two side frames 3 or three side frames 3, if the rotating edge drop test of all sides is to be satisfied, the side of the object to be tested 1 can be changed by adjusting the position of the object to be tested 1 or adjusting the relative position relationship of the side frames on the experimental device. The adjustment of the position of the object to be tested 1 or the experimental device here is actually achieved by rotation. The rotation can be specifically achieved by means of a driving motor or other components that can achieve direction reversal. After the drop test of the target side is completed, the angle of the object to be tested is turned to keep the direction of the side frame unchanged, or the experimental device is turned as a whole to keep the direction of the object to be tested unchanged, so as to achieve the switching of the target side targeted by the drop test. For example, taking the motor driving the experimental device to rotate, and setting two side frames 3 for the object to be tested as an example, after the drop test of the target side is carried out, the position of the object to be tested is kept unchanged, and the motor is connected to the test frame 2 to drive the experimental device to rotate 180° as a whole, so that the drop test of the side opposite to the target side can be carried out.

[0070] In another specific embodiment, four side frames 3 are arranged on the test frame 2, wherein one side frame 3 supports side A, another side frame 3 supports side B, another side frame 3 supports side C, and another side frame 3 supports side D. The target side A is the side that needs to fall. In this case, when performing the rotating edge drop test, the three side frames 3 corresponding to the supporting sides A, B, and C are made to fall under the action of gravity, and the side frame 3 corresponding to the D side is kept in the original position, so that the rotating edge drop test of the target side A can be realized. If the rotating edge drop test of other sides is required, it is only necessary to control the other three corresponding side frames 3 to fall. If the rotating edge drop test of the D side is to be performed, the side frame 3 supporting the D side, and the side frame 3 supporting the B side and the side frame 3 supporting the C side can be made to fall under the action of gravity.

[0071] In another specific embodiment, more than four side frames 3 are provided on the test frame 2, and one side of the object to be tested 1 can be supported by one side frame 3, or by two or more side frames 3. When two or more side frames 3 are required for support, they can be specifically configured in combination with the specific shape of the side of the object to be tested 1, so as to ensure reliable and effective support for different forms of side edges.

[0072] The stop assembly 5 is connected to the test frame 2 to form a fixation, and the connection between the stop assembly 5 and the side frame 3 is a lockable or unlockable state connection. Specifically, the stop assembly 5 can lock the side frame 3 to make the side frame 3 immovable, so that the side corresponding to the side frame 3 is immovable; or the stop assembly 5 can unlock the side frame 3 to allow the side frame 3 to move up and down.

[0073] The lifting assembly 4 is arranged on the lower side of the side frame 3. The lower side here refers to a certain distance between the two in the height direction in the initial state. Figure 6 As shown, this distance is the height of the drop in the rotating edge drop test. The lifting assembly 4 is specifically a component for realizing the reset of the side frame 3 and the reset of the entire device.

[0074] Specifically, when performing the rotating edge drop test, take side A as the target side as an example. In the initial state, please refer to Figure 6 , the stopper assembly 5 locks all the side frames 3 so that all the side frames 3 are supported on the side of the object to be measured 1, and all the side frames 3 are at a certain distance from the lifting assembly 4;

[0075] At the beginning of the test, the control element controls the stopper assembly 5 corresponding to the side frame 3 corresponding to the A side, the B side and the C side to operate, so as to unlock the side frame 3 corresponding to the A side, the B side and the C side, so that the side frame 3 corresponding to the A side, the B side and the C side can fall onto the lifting assembly 4 under the action of gravity. In this process, the comprehensive motion trajectory of the object to be tested 1 is the falling of the rotating edge, and the falling test of the rotating edge of the A side is completed;

[0076] After completing the rotating edge drop test of side A, the lifting assembly 4 is controlled by the control element to rise, so as to lift the upper side frame 3 to the initial state, and then the stopper assembly 5 is controlled by the control element to lock the lifted side frame 3, so that all the side frames 3 are supported on the lower side of the object to be tested 1, and the corresponding object to be tested 1 is also reset to the initial state, please refer to Figure 7 ; Further, the lifting assembly 4 is controlled to descend through the control element, so that the lifting assembly 4 is reset to the initial state, and the distance between the lifting assembly 4 and the side frame 3 is kept at the distance value in the initial state. At this time, the entire experimental device completes the reset process, and the rotating edge drop test of other sides can continue. The lifting process and the actual lifting height increase the standardization, without the operator's manual visual inspection, to prevent large errors caused by visual operation, and to ensure the accuracy and effectiveness of the drop test.

[0077] The operation of the lifting assembly 4 and the stop assembly 5 is controlled by the control element to achieve process control and resetting of the drop test, without the need for close manual operation, thus ensuring the safety and reliability of the test; the drop control in the specific test process is achieved through the control element, without the need for repeated manual adjustments and operations, thus avoiding human errors, simplifying the test process, saving manpower and material resources, and improving test efficiency and test accuracy and effectiveness.

[0078] Through the above-mentioned experimental device, the lifting process of the lifting component 4 and the actual lifting height are standardized, and the method of relying entirely on the visual inspection of the driving operator is abandoned, so as to prevent large errors caused by visual manual operation; the actual lifting height process of the object to be tested 1 is standardized, and once a problem occurs in the experiment, the previous experimental process can be completely reproduced to facilitate research by R&D personnel; there is no need for frequent manpower close operation to ensure the safety of the operation, the test process is simple and reliable, the cost is low, and the test efficiency and test accuracy and effectiveness are high.

[0079] Based on the above embodiments, please refer to Figure 5 , Figure 8 , Figure 7The side frame 3 includes a connecting portion 31 and a first supporting portion 32 connected thereto. The top plane of the first supporting portion 32 is lower than the top plane of the connecting portion 31 to form a side support for the object to be tested 1. In the initial state, the circumference of the object to be tested 1 is supported in the space surrounded by at least two side frames 3.

[0080] By setting the height relationship between the top plane of the first supporting portion 32 and the top plane of the connecting portion 31, the side frame 3 has a stepped structure, thereby ensuring reliable and effective support for the object to be tested 1, ensuring the reliable stability of the object to be tested 1, and ensuring the reliability of the rotation drop test on the side of the object to be tested 1.

[0081] In this embodiment, the connection relationship between the connecting portion 31 and the first supporting portion 32 is preferably integrally formed, so as to ensure the structural strength of the side frame 3 and reliable and effective support for the object to be tested 1, thereby ensuring reliable and effective testing.

[0082] Furthermore, the stopper assembly 5 is arranged through the connection part 31, and the first support part 32 is arranged relatively close to the center of the test frame 2. The arrangement of the stopper assembly 5 and the connection part 31 does not affect the support of the first support part 32 for the object to be tested 1. When the stopper assembly 5 is in the unlocked state, the connection part 31 can move along the height direction of the stopper assembly 5 to realize the lifting and lowering of the side frame 3 as a whole.

[0083] Specifically, the downward movement of the connecting portion 31 along the height direction of the stop assembly 5 is achieved by relying on its own gravity, which corresponds to the rotational falling process. Specifically, the target side to be tested and the connecting portion 31 of the side frame 3 corresponding to the two side edges adjacent to the target side are moved downward along the height direction of the stop assembly 5 to perform a rotational edge drop test on the target side; the upward movement of the connecting portion 31 along the height direction of the stop assembly 5 is achieved by lifting with the help of the lifting assembly 4, which corresponds to the process of resetting the device. This process specifically lifts the fallen side frame 3 to the initial position, effectively resetting the side frame 3, and waiting for the next (next side) rotational edge drop test.

[0084] When the stopper assembly 5 is in the locked state, the side edge of the object to be tested 1 is supported on the first support portion 32, and the corresponding side frame 3 remains stationary. When the rotating edge drop test is performed on the target side edge, the side frame 3 that remains stationary is specifically the side frame 3 corresponding to the side edge opposite to the target side edge.

[0085] In this embodiment, the overall structure of the side frame 3 can be a trapezoidal structure, a square structure or other structures, which can achieve reliable and effective support for the side of the object to be measured 1 and can be freely raised and lowered.

[0086] Based on any of the above embodiments, the connection portion 31 extends toward the center of the test frame 2 and its size is reduced, so that a movable gap 33 is formed between two adjacent connection portions 31; Figure 8As shown, two adjacent connection parts 31 do not contact each other during the lifting and moving, and the corresponding side frames 3 as a whole do not interfere with each other during the lifting and moving process, so that the movement of each side frame 3 can be controlled accordingly according to the actual drop test requirements.

[0087] The movable gap 33 is specifically a strip gap, and this gap cannot be set too large to ensure the structural strength of the side frame 3 and further ensure that the side frame 3 reliably supports the side of the object to be measured 1.

[0088] Please refer to Figure 5 , Figure 1 The first support portion 32 is reduced in size toward the center of the test frame 2. The first support portion 32 and the connecting portion 31 are both trapezoidal in shape. By setting the size reduction form, while forming the active gap 33, the first support portion 32 has a larger supporting area on the side of the object to be measured 1, thereby ensuring reliable and effective support for the object to be measured 1.

[0089] The maximum dimension of the first support portion 32 in the length direction is smaller than the minimum dimension of the connecting portion 31 in the length direction. The maximum and minimum dimensions are based on the length direction of the side frame 3. Figure 5 As shown, the direction indicated by the arrow at E is the length direction. This arrangement ensures that the overall length of the first support portion 32 does not interfere with the generation of the active gap 33, thereby ensuring the flexibility and freedom of movement of each side frame 3.

[0090] The maximum dimension of the first supporting portion 32 in the length direction is equal to the minimum dimension of the connecting portion 31, and the side frame 3 as a whole is a ladder-like structure with a stepped structure, such as Figure 5 As shown, the movable gap 33 can be minimized to ensure the supporting effect of the side frame 3 on the object to be measured 1.

[0091] On the basis of any of the above embodiments, if the experimental device is applied to a server, the cabinet of the server is generally very high and has a very obvious risk of overturning and tilting. After the cabinet is lifted on one side, the risk of overturning of the cabinet is higher, which increases the safety hazard of the experimental process. Therefore, at least two side frames 3 are arranged in the test frame 2 to support the object to be tested 1 in the test frame 2 to form a protection, so that the object to be tested 1 is subjected to a rotating edge drop test in the test frame 2. The test frame 2 effectively supports the object to be tested 1 after the fall, effectively avoiding the overturning of the object to be tested 1 during the test, reducing the reliability hazard during the test, and significantly improving the safety of the experiment. The entire process of the drop test relies on control components, so there will be no close-range manual operation, further improving the safety of the experiment.

[0092] On the basis that the test frame 2 has a certain strength and can avoid overturning, an opening can be set on the side of the test frame 2 to facilitate observation of the falling situation and the movement of each component, and to save material processing costs. The size of the opening needs to prevent the object 1 to be tested from falling from here during the falling process, that is, the opening cannot be set too large, and the specific size can be flexibly set in combination with actual operation conditions and practice conditions.

[0093] There is a gap between each side of the test frame 2 and the connecting portion 31 of the side frame 3 for spatial limitation when the target side falls. The spatial limitation here is essentially to limit the overall deflection of the object to be tested 1 when performing a drop test on the target side, so as to avoid excessive deflection of the object to be tested 1 affecting the effectiveness of the drop test.

[0094] Based on any of the above embodiments, the stop assembly 5 includes a guide column 51, a stop block 52 and a motor. Figure 1 , Figure 3 .

[0095] One end of the guide column 51 is inserted into the side frame 3 , and the other end of the guide column 51 is fixed to the bottom of the test frame 2 to form a reliable support. The fixation here can be welding or one-piece molding to ensure the operating reliability of the guide column 51 .

[0096] The guide column 51 is provided with a stop hole 511 , and the stop block 52 can extend out of or retract into the stop hole 511 . Specifically, the stop block 52 is located at the lower side of the side frame 3 , and is used to stop the side frame 3 to lock it or to unlock the side frame 3 .

[0097] Specifically, the stop block 52 can be rotated to extend out of the stop hole 511 to achieve locking of the corresponding side frame 3, or the stop block can be rotated to be received in the stop hole 511 to achieve unlocking of the corresponding side frame 3.

[0098] The number of guide posts 51 of each side frame 3 can be one, two, three or more according to actual conditions, and can be flexibly set based on actual operating conditions.

[0099] The motor is connected to the stop block 52 , and the stop block 52 is rotated in the stop hole 511 by the rotation of the motor. The motor is specifically a servo motor.

[0100] The motor signal is connected to the control element, and the control element controls the forward or reverse rotation of the stop block 52 to achieve the process of extending the stop block 52 out of the stop hole 511 or retracting the stop block 511.

[0101] By directly driving the stop block 52 with a motor, the control is simple and reliable, and reliable and accurate unlocking and locking of the side frame 3 can be achieved.

[0102] Based on any of the above embodiments, please refer to Figure 3 , Figure 4 The stop block 52 includes a second supporting portion 522 and a rotating portion 521 connected thereto. The rotating portion 521 is connected to the motor via a rotating shaft. The motor can be fixed on the test frame 2 to form a reliable support. The rotating shaft is connected to the output end of the motor and extends into the stop hole 511 and is connected to the stop block 52. The rotation of the rotating shaft is used to rotate the stop block 52, so that the second supporting portion 522 can be extended or retracted into the stop hole 511.

[0103] There is a height difference between the top surface of the rotating portion 521 and the top surface of the second supporting portion 522, and the top surface of the rotating portion 521 is lower than the top surface of the second supporting portion 522. The setting of this height difference enables the side surface of the second supporting portion 522 to fit with the guide column 51 to form a support limit when the second supporting portion 522 extends out of the stop hole 511, thereby avoiding the deviation of the second supporting portion 522. At the same time, the top surface of the second supporting portion 522 fits with the lower side of the side frame 3 to lock the side frame 3, thereby ensuring reliable and effective support for the side frame 3.

[0104] By limiting the specific structural form of the stop block 52, the stop assembly 5 can reliably and effectively lock or unlock the side frame 3, thereby ensuring the reliability and effectiveness of the rotation drop test process of the side frame 3, ensuring the reliable resetting of the experimental device, and improving the reliability of the experimental device.

[0105] Based on any of the above embodiments, please refer to Figure 1 At least two stopper assemblies 5 are provided in the length direction of the side frame 3. Through the provision of at least two stopper assemblies 5, reliable and effective support is provided for the lower side of the side frame 3, thereby ensuring the reliable stability of the object to be tested 1 supported on the side frame 3.

[0106] Please refer to Figure 4 , Figure 6 , an angle detection element is provided on the rotating part 521 or rotating shaft corresponding to each stopper assembly 5, and the angle detection element is connected with the control element signal to feedback the extension of the stopper block 52 of each stopper assembly 5, so as to ensure that the extension and retraction of the stopper block 52 on each side frame 3 are well consistent. The consistency here specifically means that the detection value of each angle detection element should ensure high consistency, so as to ensure that the side frame 3 has good stability when the second support part 522 of the stopper block 52 locks the side frame 3, so as to avoid affecting the reliable and stable support of the object to be tested 1 due to the different heights of each position of the side frame 3; and ensure that when the stopper block 52 unlocks the side frame 3, the second support part 522 of each stopper block 52 is retracted reliably, so as to avoid affecting the lifting process of the side frame 3. If the rotation angle of a stopper block 52 deviates, it needs to be fed back to the control element in time, and then prompted by the control element, so that the staff can conduct relevant inspections in time, so as to ensure the consistency of the height of each position of each side frame 3, and ensure the effective and accurate test of the drop experiment.

[0107] On the basis that an angle detection element is provided on the rotating part 521 or the rotating shaft corresponding to each stop assembly 5, the control element can also simultaneously determine the support conditions of two or three side frames 3. For example, when performing a rotating edge drop test on side A, the locking effect of the side frames 3 corresponding to the three sides A, B and C is simultaneously determined by the control element, as well as the unlocking effect of the side frames 3 corresponding to the three sides A, B and C, thereby ensuring the effectiveness and accuracy of the drop experiment.

[0108] On the basis of any of the above embodiments, a limiting portion is provided at the top of the guide column 51, and the limiting portion is used to limit the extreme position of the side frame 3 to rise, so as to prevent the side frame 3 from slipping off the guide column 51 when the lifting assembly 4 drives the side frame 3 to rise, thereby ensuring the safety and reliability of the test. In addition, the setting of the limiting portion can also calibrate the reset position of the side frame 3, so as to ensure the reliable reset of the side frame 3 and the accuracy and effectiveness of multiple drop tests.

[0109] Based on any of the above embodiments, the guide column 51 extends a certain distance from the top of the side frame 3 to prevent the side frame 3 from slipping off the guide column 51. The certain distance extended here is greater than the maximum distance that the side frame 3 can move upward, so as to prevent the side frame 3 from slipping off the guide column 51 and ensure the safety and reliability of the test.

[0110] Based on any of the above embodiments, either the side frame 3 or the guide column 51 is provided with a slide rail, and the other is provided with a slider, and the slider and the slide rail are slidably connected to limit the moving direction of the side frame 3.

[0111] Taking a specific implementation as an example, the guide column 51 is inserted into the plug-in hole of the side frame 3, and a slider can be set in the plug-in hole. The slider here can be a smaller protruding structure. Through the cooperation between the protruding structure and the slide rail on the guide column 51, the direction of the side frame 3 is accurate when it is lifted or lowered, thereby ensuring the accuracy and effectiveness of the rotation drop test.

[0112] Taking another specific implementation as an example, the guide column 51 is inserted into the plug-in hole of the side frame 3, a slide rail can be set in the plug-in hole, and a protrusion structure can be set on the guide column 51. The accuracy of the side frame 3 in the lifting direction is achieved through the cooperation of the protrusion structure and the slide rail, thereby ensuring the accuracy and effectiveness of the rotation drop test.

[0113] Based on any of the above embodiments, please refer to Figure 1 , Figure 2 , the lifting assembly 4 comprises:

[0114] A lifting member 41 is connected to the bottom of the test frame 2 and may be a gas cylinder or an oil cylinder for lifting and lowering the side frame 3;

[0115] The lifting frame 42 is connected to the moving end of the lifting member 41 and is located at the lower side of the side frame 3. The lifting frame 42 is connected to multiple lifting members 41 to achieve the lifting and resetting of the side frame 3 corresponding to the target side and the side adjacent to the target side of the object 1 to be tested.

[0116] Specifically, during the application process, the lifting frame 42 is connected to the moving end of the lifting member 41. In the initial state, the lifting frame 42 and the bottom of the side frame 3 are at a certain distance. During the test, the side frames 3 corresponding to the target side and the side adjacent to the target side of the object 1 to be tested are unlocked by the corresponding stopper assembly 5, so that the corresponding side frame 3 falls onto the lifting frame 42 under the action of gravity to perform a rotating edge drop test of the target side. After the drop test is completed, the lifting member 41 is controlled by the control element to drive the lifting frame 42 to move upward to achieve the lifting of the corresponding side frame 3, drive the side frame 3 to reset, and reset the object 1 to be tested to the initial state. Further, the stopper assembly 5 is controlled by the control element to operate so as to reliably support the reset side frame 3, and then the lifting member 41 is controlled to drive the lifting frame 42 to move downward to the initial position, so that the lifting assembly 4 as a whole reaches the reset state and waits for the next drop test. No operator manual visual inspection is required, and no manual repeated adjustment operation is required, thereby avoiding human errors, simplifying the test process, saving manpower and material resources, and improving test efficiency and test accuracy and effectiveness.

[0117] The plurality of lifting members 41 are connected via the lifting frame 42 to ensure reliable and effective lifting of the side frame 3 and the object to be tested 1 , thereby ensuring the reliability and effectiveness of the drop test.

[0118] On the basis of any of the above embodiments, the lifting frame 42 includes a plurality of cross-arranged profiles to ensure the structural strength of the lifting frame 42 and to ensure that the lifting frame 42 can reliably lift the side frame 3 and the object to be tested 1; there is a gap between two adjacent profiles, and this gap allows the stop assembly 5 to be set, so that the lifting and lowering process of the side frame 3 does not interfere with the stop assembly 5, thereby ensuring the reliability of the rotating edge drop test.

[0119] The size of the lifting frame 42 is not less than the size of the structure formed by all the side frames 3, ensuring that the lifting frame 42 can contact each side frame 3 corresponding to each side to perform lifting operations, so that the experimental device can be applied to the rotating edge drop test of all sides, improving applicability and market value.

[0120] On the basis of any of the above embodiments, a height sensor is provided on the side frame 3, and the height sensor is connected to the control element to monitor the moving distance of each side frame 3; when the free-falling side frame 3 is reset by the lifting member 41 after the drop test is completed, the reset status of each side frame 3 can be obtained through the height sensor, providing a theoretical basis for the reset status of the experimental device.

[0121] The control element is used to determine the reset status of each side frame 3 according to the monitoring information of the height sensor. If there is a side frame 3 that has not been reset, the control element controls the lifting member 41 to descend to the initial position, and then lifts the side frame 3 that has not been reset, so that the experimental device can be accurately and effectively reset after the fall, ensuring the accuracy of the next drop test, and restoring the last drop test for the convenience of research and development personnel.

[0122] In summary, take the cabinet as an example. Figure 8 As shown in the figure, the sides of the cabinet are specifically side A, side B, side C, and side D. Next, the specific use process of the rotating edge drop test device is introduced with the target side as side A:

[0123] In the initial state, the control element controls the stopper assemblies 5 corresponding to the A side, the B side, the C side, and the D side to operate, and the stopper 52 extends out of the stopper hole 511 and is supported under the side frame 3 to lock the four side frames 3 corresponding to the A side, the B side, the C side, and the D side. There is a certain distance between the side frame 3 and the lifting assembly 4, such as Figure 6 As shown;

[0124] When performing a drop test, after the control element determines the target side, the control element controls the stopper assembly 5 corresponding to the A side, the B side, and the C side to operate, so that the stopper block 52 retracts into the stopper hole 511, so that the three locked side frames 3 can be raised and lowered, so as to unlock the side frames 3 corresponding to the A side, the B side, and the C side. At this time, the side frame 3 corresponding to the D side remains locked, and the side frames 3 corresponding to the A side, the B side, and the C side fall onto the lifting frame 42 of the lifting assembly 4 under the action of gravity;

[0125] After the drop test is completed and the experimental device needs to be reset, the control element controls the lifting assembly 4 to drive the three side frames 3 on the lifting frame 42 to move upward at the same time, so as to drive the side frames 3 corresponding to the A side, the B side and the C side to rise for reset; then the control element controls the stopper assemblies 5 corresponding to the A side, the B side and the C side to operate to lock the side frames 3; then the control element controls the lifting assembly 4 to move downward for reset, waiting for the next drop test.

[0126] If other side edges are replaced to perform the rotating edge drop test, it is only necessary to change the position of the dropped side frame 3. The other steps can refer to the above process and will not be described in detail.

[0127] In addition to the above-mentioned rotating edge drop test device, the present invention also provides a control method for the rotating edge drop test device disclosed in the above-mentioned embodiment, and the control method includes:

[0128] In the initial state, the control element controls the stopper assembly 5 to work to lock the side frame 3, and there is a certain distance between the side frame 3 and the lifting assembly 4;

[0129] When performing a drop test, after the control element determines the target side, the control element controls the stop assembly 5 to operate to unlock the side frame 3 corresponding to the target side and the side adjacent to the target side, so that the side frame 3 falls onto the lifting assembly 4;

[0130] After the drop test is completed and the experimental device is reset, the control element controls the lifting assembly 4 to move upward to drive the fallen side frame 3 to rise for reset; then the control element controls the stop assembly 5 to operate to lock the side frame 3; then the control element controls the lifting assembly 4 to move downward for reset.

[0131] Based on the above embodiment, the control element is connected to a monitoring element for detecting the type of the object to be tested 1. The control element analyzes the type of the object to be tested 1 according to the monitoring information of the monitoring element and forms an operation instruction. The control element controls the operation of the lifting assembly 4 and the stop assembly 5 according to the operation instruction.

[0132] If the object to be tested 1 is a cabinet, the monitoring element can detect the model of the cabinet, and the control element stores the drop instructions of the cabinet of the corresponding model. Each model of cabinet corresponds to a set of drop instructions, and the drop instructions specifically include the test sequence, lifting height, test side, etc., to improve the applicability of the entire device.

[0133] In a specific embodiment, the control element may be integrated into a control device, which includes a visual operation panel that can monitor and control the entire drop test process in real time.

[0134] On the basis of any of the above embodiments, a height sensor is provided on the side frame 3 for detecting the lifting distance of the side frame 3;

[0135] The control element determines the reset status of the side frame 3 and gives a prompt by analyzing the lifting distance and preset value of any side frame 3. The prompt here can be made through an indicator light or a prompt sound to remind the staff whether it is reset in place or not. If one or more are not reset in place, the control element needs to control the lifting assembly 4 to lift again after reset, or control the lifting assembly 4 to continue to lift upward until the height sensor detects a value that is consistent with the preset value. At this time, the fallen side frame 3 is accurately reset to the initial state, and the experimental device is accurately reset to wait for the next drop test, ensuring the reliability and effectiveness of multiple drop tests of the entire experimental device.
