In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0057] In some embodiments of the present application, a testing device 100, 100' is provided. Referring to Figures 1 to 17 , the testing device 100 includes a main body 10, a first acquisition member 20, a second acquisition member 30, and a data acquisition unit 40.

[0058] Referring to Figures 5 to 6 and Figure 13 , the main body 10 can be detachably connected to one end of a connecting arm 320 along the length direction X of the connecting arm 320. The other end of the length direction X of the connecting arm 320 is used to connect to a cabin door 310 of an aircraft 300. The main body 10 can move along the height direction Z of the cabin door 310 to drive the connecting arm 320 to rotate, so as to open or close the cabin door 310.

[0059] Referring to Figures 1 to 2 , Figures 5 to 9 and Figure 13 , the first acquisition member 20 is arranged on the main body 10. The first acquisition member 20 can move along with the main body 10. Specifically, the first acquisition member 20 can move along with the main body 10 along the height direction Z of the cabin door 310 to acquire the force applied to the main body 10 during the movement of the main body 10 along the height direction Z.

[0060] Referring to Figures 1 to 2 , Figures 5 to 9 and Figure 13 , the second acquisition member 30 is arranged on the main body 10. The second acquisition member 30 can move along with the main body 10. Specifically, the second acquisition member 30 can move along with the main body 10 along the height direction Z of the cabin door 310 to acquire the rotation angle during the rotation of the main body 10 driving the connecting arm 320.

[0061] Referring to Figure 3 , the first acquisition member 20 is communicatively connected to the data acquisition unit 40 to transmit the acquired force data. Specifically, the output end of the first acquisition member 20 is communicatively connected to the input end of the data acquisition unit 40 to transmit the acquired force data to the data acquisition unit 40. The second acquisition member 30 is communicatively connected to the data acquisition unit 40 to transmit the acquired angle data. Specifically, the output end of the second acquisition member 30 is communicatively connected to the input end of the data acquisition unit 40 to transmit the acquired angle data to the data acquisition unit 40. Referring to Figure 18 , the data acquisition unit 40 can output a force-angle test curve according to the force data and the angle data.

[0062] During the installation and daily maintenance of an aircraft cabin door, the operating force of the cabin door handle is directly related to the opening, closing, and locking performance of the cabin door. Therefore, the operating force of the cabin door handle needs to meet the design standards to ensure the reliability and safety of the opening and closing of the cabin door. If the operating force deviates from the standard value, the following problems may occur:

[0063] 1. Safety hazards: Excessive operating force may cause handle failures or render the handle inoperable, affecting quick operations in emergency situations; insufficient operating force may lead to locking failures and cause the hatch to open unexpectedly.

[0064] 2. Inefficient operation: Inaccurate operating force data may result in repeated debugging during installation or maintenance, wasting time and resources.

[0065] Existing test devices are usually large fixed devices or handheld test devices with low precision. For large fixed devices, they are large in size, inconvenient to carry and use in narrow spaces. The disassembly and assembly process between the handheld test device and the hatch handle is complex, and the disassembly time is too long. Especially in high and low temperature environments, the surface temperature of the hatch reaches a temperature that cannot be tolerated by the human hand. Therefore, gloves need to be worn to solve this problem. The original method of tightening screws to clamp the test device and the handle is even more disadvantageous for operating while wearing gloves. Coupled with the influence of the surrounding extreme environment, there are certain test safety risks and it affects the test efficiency. Moreover, existing test devices are usually installed on the handle, and the connecting arm is rotated to open or close the hatch by driving the handle. There is an initial angle in the initial state of the assembly of the test device and the handle, which affects the measurement accuracy of the angle data.

[0066] However, for the test devices 100 and 100' provided in the embodiments of the present application, the main body 10 can be detachably connected to one end of the connecting arm 320 in the length direction X. The other end of the connecting arm 320 in the length direction X is used to connect to the hatch 310. The main body 10 can move along the height direction Z of the hatch 310 to drive the connecting arm 320 to rotate, so as to open or close the hatch 310. The first acquisition member 20 and the second acquisition member 30 are respectively arranged on the main body 10. The force applied to the main body 10 during the movement of the main body 10 along the height direction Z (specifically, the operating force for operating the hatch 310 to open or close) is acquired by the first acquisition member 20. And the first acquisition member 20 can transmit the acquired force data to the data acquisition unit 40. The rotation angle during the rotation of the main body 10 driving the connecting arm 320 is acquired by the second acquisition member 30. And the second acquisition member 30 can transmit the acquired angle data to the data acquisition unit 40. The data acquisition unit 40 can output a force-angle test curve according to the force data and the angle data, so as to analyze the change of the force with the angle during the opening or closing of the hatch, and determine whether the operating force required for opening or closing the hatch 310 meets the standard value. Thus, the connecting arm 320 and the hatch 310 can be adjusted according to the force-angle test curve, so that the operating force required for opening or closing the hatch 310 meets the standard value, ensuring the reliability and safety of opening or closing the hatch 310.

[0067] In addition, the structural design in which the main body 10 directly connects to the connecting arm 320 instead of the handle can eliminate the initial angle caused by the existing test device and the handle device, enabling the test devices 100 and 100' to perform in-situ tests quickly and accurately, ensuring the precise alignment of the test point and the force application point, avoiding mechanical deviations that may be introduced during the disassembly process, guaranteeing the accuracy of the acquisition of force data and angle data, and further ensuring the accuracy of the output of the test results, so as to accurately adjust the connecting arm 320 and the hatch 310 according to the force and angle test curves, ensuring that the operating force for opening or closing the hatch 310 meets the standard value, and further ensuring the reliability and safety of opening or closing the hatch 310. Moreover, the acquisition of force data and angle data can be completed in a single operation, avoiding the cumbersome steps of reinstalling the equipment. The automatic data synchronization and processing function of the data acquisition unit 40 reduces the skill requirements for the operator and is suitable for maintenance personnel at different levels.

[0068] In addition, through the structural design in which the test devices 100 and 100' are connected to the connecting arm 320 via the main body 10, the opening or closing of the hatch 310 can be tested under extreme environments such as high temperature and low temperature, thus ensuring the reliability and safety of opening or closing the hatch 310 under extreme environments.

[0069] Moreover, the structural design in which the main body 10 directly connects to the connecting arm 320 instead of the handle causes no damage to the surface of the hatch 310 handle, avoids additional maintenance requirements caused by test operations, and enables the test devices 100 and 100' to adapt to the narrow working environment inside the aircraft 300, such as the limited space near the cargo hatch, greatly improving the operation convenience. The structural design in which the main body 10 directly connects to the connecting arm 320 can quickly diagnose potential problems of the handle assembly (the handle and the connecting arm 320), such as abnormal wear of the locking mechanism or stress concentration points of the connecting arm.

[0070] The structural design of the detachable connection between the main body 10 and the connecting arm 320 does not require adjustment of the original installation state after the test is completed, ensuring the immediate reliability of the hatch 310 operation. Moreover, the disassembly and assembly efficiency is high, no additional tools are required for disassembly and assembly, and a single person can complete the equipment deployment, reducing the work preparation time. It is convenient for transportation. The weight of each test device 100 and 100' is less than 2 kg, and the overall size is less than 30 cm × 20 cm × 10 cm. The miniaturized and lightweight design makes it suitable for carrying around or transporting by ordinary express delivery, meeting the global maintenance requirements. The maintenance cost is low. The modular structural design between the main body 10, the first acquisition component 20, the second acquisition component 30, and the data acquisition unit 40 facilitates the replacement of individual components, reducing the maintenance cost and extending the service life of the equipment.

[0071] In some embodiments, the hatch 310 can be any one of a boarding door, an emergency door, and a cargo hatch.

[0072] In some embodiments, the first acquisition component 20 is a force sensor. The force sensor can achieve high-precision acquisition of mechanical data, with a measurement range of 0 N to 500 N and an accuracy of 0.1 N. In some other implementation manners, the first acquisition component 20 can adopt other devices other than sensors, as long as it can acquire the force data applied to the handle 50.

[0073] In some embodiments, the second acquisition component 30 is an inclination sensor or an angle sensor. In some other implementation manners, the second acquisition component 30 can adopt other devices other than sensors, as long as it can acquire the angle during the rotation of the handle 50 driving the connecting arm 320.

[0074] In some embodiments of the present application, a testing method is provided, and the testing method includes the following steps:

[0075] (1) Connect the main body 10 to the connecting arm 320. Specifically, detachably connect the main body 10 to one end of the connecting arm 320 along the length direction X.

[0076] (2) Move the main body 10 along the height direction Z to drive the connecting arm 320 to rotate until the hatch 310 is opened or closed.

[0077] Specifically, the operator holds the handle 50 and drives the handle 50 to move along the height direction Z. The handle 50 drives the main body 10 to move along the height direction Z, and the main body 10 drives the connecting arm 320 to rotate. Among them, the operator applies an upward pulling force to the handle 50 to drive the main body 10 to rise along the height direction Z, and the main body 10 drives the connecting arm 320 to rotate until the hatch 310 is opened; the operator applies a downward pressing force to the handle 50 to drive the main body 10 to descend along the height direction Z, and the main body 10 drives the connecting arm 320 to rotate until the hatch 310 is closed.

[0078] (3) Analyze the force data collected by the first acquisition component 20 and the angle data collected by the second acquisition component 30 through the data acquisition unit 40, and output a force-angle test curve through the data acquisition unit 40. Among them, the force-angle test curve includes the force-angle test curve during the process of the connecting arm 320 driving the hatch 310 to open, and the force-angle test curve during the process of the connecting arm 320 driving the hatch 310 to close.

[0079] Specifically, collect the manipulation force applied by the operator on the handle 50 for driving the connecting arm 320 to rotate through the first acquisition component 20. The first acquisition component 20 transmits the collected force data to the data acquisition unit 40. Collect the rotation angle during the rotation of the main body 10 driving the connecting arm 320 through the second acquisition component 30. The second acquisition component 30 transmits the collected angle data to the data acquisition unit 40. The data acquisition unit 40 analyzes the force data and the angle data, and outputs a force-angle test curve.

[0080] In some embodiments, the testing method further includes:

[0081] (4) Comparing the force and angle test curve obtained in step (3) with the force and angle standard curve pre-stored in the data acquisition unit 40 through the data acquisition unit 40.

[0082] In some embodiments, the time required for the main body 10 to drive the connecting arm 320 to rotate to open or close the hatch 310 can also be collected, so as to output a force-time test curve and / or an angle-time test curve through the data acquisition unit 40, which can be specifically selected according to actual usage requirements.

[0083] In some embodiments, a torque sensor can also be provided on the main body 10 to collect the torque required for the main body 10 to drive the connecting arm 320 to rotate to open or close the hatch 310, so as to output a torque-angle test curve, a torque-force test curve, and / or a torque-time test curve through the data acquisition unit 40, which can be specifically selected according to actual usage requirements.

[0084] In some embodiments, the data acquisition unit 40 includes a host computer and a slave computer. The first acquisition member 20 and the second acquisition member 30 are respectively communicatively connected to the slave computer, and the slave computer is communicatively connected to the host computer. The data acquisition unit 40 outputs the force and angle test curve through the host computer, and the force and angle standard curve is stored in the host computer. The force and angle test curve and the force and angle standard curve are compared through the host computer.

[0085] In some embodiments, referring to Figures 1 to 2 、 Figures 5 to 9 and Figure 13 , the testing devices 100, 100' further include a handle 50. The handle 50 is provided on the main body 10. The handle 50 can drive the main body 10 to move along the height direction Z. The handle 50 extends along the width direction Y of the hatch 310, and the extending direction of the handle 50 is perpendicular to the length direction X of the connecting arm 320. The setting of the handle 50 facilitates the operator to drive the main body 10 to move along the height direction Z, improving the convenience of operation. Moreover, the structural design in which the extending direction of the handle 50 is perpendicular to the length direction X of the connecting arm 320 enables the connecting arm 320 to remain perpendicular to the handle 50 during rotation, thereby ensuring the accuracy of the force data collected by the first acquisition member 20 and the accuracy of the test results.

[0086] Referring to Figures 1 to 2 and Figures 4 to 6 , the main body 10 includes a first main body 10a, referring to Figure 5 and Figure 6The connecting arm 320 includes a first connecting arm 320a, and the first connecting arm 320a includes a first end 321 and a second end 322 arranged opposite to each other along the length direction X. The second end 322 is used to connect with the inner wall surface of the cabin door 310 (not shown in the figure), that is, the first end 321 of the first connecting arm 320a is used to connect with the inner handle of the cabin door 310, and the first connecting arm 320a is driven to rotate by the inner handle, so that the operator can open or close the cabin door 310 from the inside of the cabin door 310.

[0087] In some embodiments of the present application, a testing device 100 is provided. Figures 1 to 6 The testing device 100 includes a first body 10 a , a first collecting member 20 , a second collecting member 30 , a data collection unit 40 and a handle 50 .

[0088] Reference Figures 1 to 2 as well as Figures 4 to 6 The first body 10a includes a first section 101 extending along the height direction Z and a second section 102 extending along the width direction Y. The first section 101 and the second section 102 are connected to define a first accommodating cavity 103. Specifically, the first section 101 and the second section 102 are connected to form an inverted L-shaped structure. The first accommodating cavity 103 is defined between the first section 101 and the second section 102. Figures 5 to 6 The end of the first section 101 away from the second section 102 along the height direction Z can be detachably connected to the first end 321 of the first connecting arm 320a, so that the first body 10a replaces the inner handle of the cabin door 310 and is connected to the first connecting arm 320a.

[0089] Reference Figures 1 to 2 as well as Figures 5 to 6 The first collecting member 20 is disposed in the first accommodating cavity 103. Along the height direction Z, one end of the first collecting member 20 is connected to the second section 102, and the other end is connected to the handle 50. The handle 50 can drive the first body 10a to move along the height direction Z via the first collecting member 20, so that the first body 10a drives the first connecting arm 320a to rotate, thereby opening or closing the hatch 310. The handle 50 extends perpendicular to the length direction X of the first connecting arm 320a.

[0090] The first acquisition member 20 can acquire the force applied to the first body 10 a during its movement. In other words, the first acquisition member 20 can acquire the operating force that causes the first body 10 a to rise or fall along the height direction Z, and can transmit the acquired force data to the data acquisition unit 40 .

[0091] Reference Figures 1 to 2 as well as Figures 5 to 6, the second acquisition member 30 is disposed on the second section 102 of the first main body 10a. The second acquisition member 30 can acquire the rotation angle during the rotation of the first main body 10a driving the first connecting arm 30a, and can transmit the acquired angle data to the data acquisition unit 40.

[0092] Specifically, the operator drives the handle 50 to rise or fall along the height direction Z. The handle 50 drives the first main body 10a to rise or fall along the height direction Z through the first acquisition member 20. When the handle 50 drives the first main body 10a to rise along the height direction Z, the first main body 10a drives the first connecting arm 320a to rotate upward, so that the hatch 310 is opened; when the handle 50 drives the first main body 10a to fall along the height direction Z, the first main body 10a drives the first connecting arm 320a to rotate downward, so that the hatch 310 is closed.

[0093] In some embodiments, referring to Figures 1 to 2 and Figures 5 to 6 , the testing device 100 further includes a first locking member 60. Referring to Figure 2 and Figure 4 , a second receiving cavity 104 is formed at one end of the first section 101 of the first main body 10a along the height direction Z departing from the second section 102. Referring to Figure 5 and Figure 6 , the first end 321 of the first connecting arm 320a can be inserted into the second receiving cavity 104. Referring to Figure 5 and Figure 6 , one end of the first locking member 60 can extend into the second receiving cavity 104 to lock the first end 321 in the second receiving cavity 104, and the first locking member 60 can be separated from the first section 101, so that the first end 321 can be separated from the first section 101. Thus, the detachable connection between the first locking member 60 and the first main body 10a is realized. While ensuring the connection stability between the first main body 10a and the first connecting arm 320a, the quick disassembly and assembly between the first main body 10a and the first end 321 of the first connecting arm 320a are realized, improving the disassembly and assembly convenience, so that the testing device 100 is applicable to the testing requirements for opening or closing different types of hatches 310.

[0094] In some embodiments, referring to Figure 4 and Figure 6 , the first main body 10a includes a shaft rod 107. The shaft rod 107 is disposed in the second receiving cavity 104. Referring to Figure 6 , the first connecting arm 320a is inserted into the second receiving cavity 104 and sleeved on the shaft rod 107. One end of the first locking member 60 is inserted into the shaft rod 107 to lock the first end 321 of the first connecting arm 320a in the second receiving cavity 104.

[0095] In some embodiments, the first locking member 60 is threadedly connected to the shaft 107 , thereby enabling quick assembly and disassembly between the first body 10 a and the first connecting arm 320 a .

[0096] In some embodiments, the handle 50 is cylindrical in shape. A ring is connected to each end of the handle 50, and the ring is fixed to the rolling bearing by bolts. The handle 50 is also connected to the side mounting plate by bolts at both ends. The handle 50 is ergonomically designed to facilitate the operator's application of force.

[0097] In some embodiments, reference Figures 1 to 2 as well as Figures 5 to 6 The testing device 100 further includes a first frame 70, which is disposed in the first accommodating cavity 103 of the first main body 10a. The first frame 70 is connected to the end of the first collecting member 20 away from the second section 102 along the height direction Z, and the handle 50 is inscribed in the first frame 70. Figures 1 to 2 as well as Figure 6 Along the width direction Y, a gap 701 exists between the first frame 70 and the first section 101. The design of the first frame 70 ensures the installation stability of the handle 50. Furthermore, the handle 50 is connected to the first acquisition component 20 via the first frame 70, allowing the force applied to the handle 50 to be transmitted to the first acquisition component 20 via the first frame 70, ensuring the accuracy of force data collected by the first acquisition component 20. The gap 701 between the first frame 70 and the first section 101 prevents direct contact between the first frame 70 and the first body 10a, ensuring the accuracy of the force applied by the first body 10a on the first connecting arm 320a collected by the first acquisition component 20, thereby ensuring the accuracy of the test results of the testing device 100.

[0098] In some embodiments, the first frame body 70 has an overall U-shape or a concave shape, and is made of a lightweight and high-strength material, such as aluminum alloy.

[0099] In some embodiments, reference Figures 1 to 2 as well as Figures 5 to 6 The first body 10a further includes a first mounting plate 105, which extends along the longitudinal direction X. Along the longitudinal direction X, one end of the first mounting plate 105 is connected to the second section 102, while the other end is suspended. The second acquisition component 30 is disposed at the end of the first mounting plate 105 that is distal from the second section 102 along the longitudinal direction X. The provision of the first mounting plate 105 provides mounting space for the second acquisition component 30. While ensuring the installation stability of the second acquisition component 30, the second acquisition component 30 is spaced apart from the first acquisition component 20 along the longitudinal direction X, thereby preventing interference between the first acquisition component 20 and the second acquisition component 30 and ensuring the accuracy and stability of data collection.

[0100] In some embodiments, the first mounting plate 105 and the second section 102 are connected by bolts.

[0101] In some embodiments of the present application, a testing method is provided. The testing method uses the testing device 100 described above for testing, and the testing method includes the following steps:

[0102] S1. Connect the first main body 10a and the first connecting arm 320a.

[0103] Specifically, insert the first end 321 of the first connecting arm 320a into the second receiving cavity 104 and sleeved on the shaft rod 107, insert the first locking member 60 into the second receiving cavity 104 and insert it into the shaft rod 107, and lock the first end 321 in the second receiving cavity 104.

[0104] S2. Move the first main body 10a along the height direction Z to drive the first connecting arm 320a to rotate to open or close the hatch 310.

[0105] Specifically, the operator holds the handle 50 and drives the handle 50 to move along the height direction Z. The handle 50 drives the first main body 10a to move along the height direction Z through the first frame 70, and the first main body 10a drives the first connecting arm 320a to rotate. Among them, the operator applies an upward pulling force to the handle 50 to drive the first main body 10a to rise along the height direction Z, and the first main body 10a drives the first connecting arm 320a to rotate to open the hatch 310; the operator applies a downward pressing force to the handle 50 to drive the first main body 10a to descend along the height direction Z, and the first main body 10a drives the first connecting arm 320a to rotate to close the hatch 310.

[0106] S3. Analyze the force data collected by the first acquisition member 20 and the angle data collected by the second acquisition member 30 through the data acquisition unit 40, and output a force and angle test curve through the data acquisition unit 40. Among them, the force and angle test curve includes the force and angle test curve during the process of the first connecting arm 320a driving the hatch 310 to open, and the force and angle test curve during the process of the first connecting arm 320a driving the hatch 310 to close.

[0107] Specifically, collect the operating force applied by the operator on the handle 50 for driving the first connecting arm 320a to rotate through the first acquisition member 20. The first acquisition member 20 transmits the collected force data to the data acquisition unit 40. Collect the rotation angle during the process of the first main body 10a driving the first connecting arm 320a to rotate through the second acquisition member 30. The second acquisition member 30 transmits the collected angle data to the data acquisition unit 40. The data acquisition unit 40 analyzes the force data and the angle data, and outputs a force and angle test curve.

[0108] In some embodiments, the testing method further includes:

[0109] S4. Compare the force and angle test curve obtained in step S3 with the force and angle standard curve pre-stored in the data acquisition unit 40 through the data acquisition unit 40.

[0110] Thereby, adjust the first connecting arm 320a and the hatch 310 according to the comparison result, so that the operating force for opening or closing the hatch 310 meets the standard value, ensuring the reliability and safety of opening or closing the hatch. Among them, during the process of driving the first connecting arm 320a to rotate to drive the hatch 310 to open or close, there are multiple nodes, and the adjustment of the first connecting arm 320a and the hatch 310 can be achieved by adjusting these multiple nodes. For example, these multiple nodes include but are not limited to the contact between the latch and the latch groove, the seal on the hatch 310 reaching the maximum compression amount, and the seal disengaging from the seal stop.

[0111] In some embodiments, the standard value of the force for opening the inner handle of the hatch 310 under normal and emergency conditions does not exceed 222 N (50 lb).

[0112] In some embodiments, referring to Figures 7 to 9 and Figure 13 , the main body 10 includes a second main body 10b, referring to Figure 13 and Figure 16 , the connecting arm 320 includes a second connecting arm 320b. The second connecting arm 320b includes a third end 323 and a fourth end 324 that are oppositely arranged along the length direction X. The fourth end 324 is used to connect to the outer wall surface (not shown in the figure) of the hatch 310. That is, the third end 323 of the second connecting arm 320b is used to connect to the outer handle of the hatch 310. By driving the second connecting arm 320b to rotate through the outer handle, the operator can open or close the hatch 310 outside the hatch 310.

[0113] In some embodiments of the present application, a test device 100' is provided. Referring to Figures 7 to 16 , the test device 100' includes a second main body 10b, a first acquisition member 20, a second acquisition member 30, a data acquisition unit 40, and a handle 50.

[0114] Referring to Figures 7 to 9 and Figure 13The second body 10b extends along the height direction Z. Along the height direction Z, one end of the first collecting member 20 is connected to one end of the second body 10b, and the other end is connected to the handle 50. The end of the second body 10b, facing away from the first collecting member 20, along the height direction Z can be detachably connected to the third end 323 of the second connecting arm 320b, thereby allowing the second body 10b to replace the outer handle of the hatch 310 and connect to the second connecting arm 320b. The second collecting member 30 is connected to the second body 10b. The handle 50 can move the second body 10b along the height direction Z via the first collecting member 20. The handle 50 extends perpendicular to the lengthwise direction X of the second connecting arm 320b.

[0115] The first acquisition member 20 can acquire the force applied to the second body 10 b during the movement of the second body 10 b. In other words, the first acquisition member 20 can acquire the operating force that causes the second body 10 b to rise or fall along the height direction Z, and can transmit the acquired force data to the data acquisition unit 40.

[0116] The second acquisition component 30 can acquire the rotation angle of the second connecting arm 30 b during the rotation of the second body 10 b and can transmit the acquired angle data to the data acquisition unit 40 .

[0117] Specifically, the operator drives the handle 50 upward or downward in the height direction Z, and the handle 50 drives the second body 10b upward or downward in the height direction Z through the first collecting member 20. The handle 50 drives the second body 10b upward in the height direction Z, and the second body 10b drives the second connecting arm 30b to rotate upward, thereby opening the hatch 310; the handle 50 drives the second body 10b downward in the height direction Z, and the second body 10b drives the second connecting arm 30b to rotate downward, thereby closing the hatch 310.

[0118] In some embodiments, reference Figures 7 to 9 as well as Figure 13 The testing device 100' further includes a second frame 71, which is connected to the end of the first acquisition component 20 facing away from the second main body 10b along the height direction Z. The handle 50 is inscribed within the second frame 71 and is connected to the first acquisition component 20 via the second frame 71. The design of the second frame 71 ensures the installation stability of the handle 50. Furthermore, the connection between the handle 50 and the first acquisition component 20 via the second frame 71 allows the force applied to the handle 50 to be transmitted to the first acquisition component 20 via the second frame 71, thereby ensuring the accuracy of the force data collected by the first acquisition component 20.

[0119] In some embodiments, the overall shape of the second frame body 71 is U-shaped or concave, and the material is a lightweight and high-strength material, such as aluminum alloy.

[0120] In some embodiments, referenceFigures 7 to 9 as well as Figure 13 The testing device 100' further includes a second mounting plate 106 extending along the longitudinal direction X. One end of the second mounting plate 106 is positioned between the second body 10b and the first collection member 20 along the longitudinal direction X. The first collection member 20 is connected to the second body 10b via the second mounting plate 106. The other end of the second mounting plate 106 is suspended in the air. The second collection member 30 is positioned at the end of the second mounting plate 106 away from the second body 10b along the longitudinal direction X. The second mounting plate 106 provides mounting space for the second collection member 30. While ensuring the stability of the second collection member 30, it also spaced the second collection member 30 from the first collection member 20 along the longitudinal direction X, preventing interference between the first and second collection members 20 and ensuring accurate and stable data collection.

[0121] In some embodiments, reference Figures 7 to 17 The testing device 100 ′ further includes a connecting plate 80 and a second locking member 61 .

[0122] Reference Figure 14 and Figure 15 The third end 323 of the second connecting arm 320b is provided with a through hole 3230 that passes through the second connecting arm 320b along the height direction Z, and the second connecting arm 320b has a hole wall 3231 that surrounds the through hole 3230 along the circumferential direction of the through hole 3230.

[0123] Reference Figures 7 to 9 as well as Figure 13 The connecting plate 80 is provided at one end of the second body 10b away from the first collecting member 20 along the height direction Z, and the connecting plate 80 can cover the through hole 3230. Figures 7 to 10 as well as Figures 12 to 16 The second locking member 61 includes a connecting rod 611 and a locking portion 612, referring to Figure 9 and Figure 12 The connecting rod 611 includes a first connecting end 6111 and a second connecting end 6112 that are oppositely arranged along the height direction Z. Figures 7 to 10 、 Figure 13 as well as Figures 15 to 16 , the connecting rod 611 is inserted into the connecting plate 80, and the first connecting end 6111 is located inside the through hole 3230. Figure 9 and Figure 12 The locking portion 612 is sleeved on the first connecting end 6111 of the connecting rod 611, referring to Figures 8 to 10 as well as Figure 15 One end of the locking portion 612 abuts against the connecting plate 80, referring to Figure 14 and Figure 15, the other end of the locking part 612 can abut against the hole wall 3231 to lock the connecting plate 80 and the second connecting arm 320b. The connecting rod 611 can drive the locking part 612 to move along the height direction Z, so that the connecting plate 80 can be assembled or separated from the second connecting arm 320b.

[0124] The setting of the connecting plate 80 enables the second main body 10b to be connected to the second connecting arm 320b through the connecting plate 80, and the shape of the connecting plate 80 is similar to the shape of the outer handle on the hatch 310. Therefore, the connecting plate 80 can replace the outer handle to be connected to the second connecting arm 320b, eliminating the initial angle problem caused by the connection with the outer handle, enabling the second main body 10b to form an in-situ connection with the second connecting arm 320b through the connecting plate 80, and further enabling the test device 100' to perform in-situ testing, ensuring the accuracy of the data collected by the first acquisition part 20 and the second acquisition part 30, and ensuring the accuracy of the test results.

[0125] The setting of the second locking member 61, the connecting rod 611 is inserted into the connecting plate 80, the locking part 612 is sleeved on the first connecting end 6111 of the connecting rod 611, and the connecting rod 611 can drive the locking part 612 to move along the height direction Z. Specifically, the connecting rod 611 drives the locking part 612 to rise along the height direction Z, so that while the locking part 612 abuts against the connecting plate 80, it also abuts against the hole wall 3231 on the second connecting arm 320b, thereby realizing the locking between the connecting plate 80 and the second connecting arm 320b; the connecting rod 611 drives the locking part 612 to descend along the height direction Z, so that the locking part 612 is separated from the connecting plate 80 and the hole wall 3231, so that the connecting plate 80 can be separated from the second connecting arm 320b, thereby realizing the detachable connection between the second main body 10b and the second connecting arm 320b, and realizing the quick disassembly and assembly between the second main body 10b and the second connecting arm 320b, improving the assembly convenience and assembly efficiency of the test device 100' and the second connecting arm 320b, and enabling the test device 100' to be applicable to the testing of different types of hatches 310.

[0126] In some embodiments, the connecting rod 611 is a threaded rod.

[0127] In some embodiments, referring to Figures 7 to 10 , Figure 12 and Figures 14 to 16 , the second locking member 61 further includes a driving part 613, referring to Figure 12, the driving part 613 is pivotally connected to the second connecting end 6112 of the connecting rod 611. The driving part 613 can drive the connecting rod 611 to move along the height direction Z, so that the locking part 612 can abut against or separate from the connecting plate 80 and the hole wall 3231. Specifically, during the process of the driving part 613 flipping from the position where the length direction of the driving part 613 is perpendicular to the length direction of the connecting rod 611 to the position where the length direction of the driving part 613 is parallel to the length direction of the connecting rod 611, the driving part 613 drives the connecting rod 611 and the locking part 612 sleeved on the connecting rod 611 to descend along the height direction Z, so that the locking part 612 separates from the abutting connecting plate 80 and hole wall 3231, so that the second main body 10b can drive the connecting plate 80 and the second locking part 61 to separate from the second connecting arm 320b, realizing the disassembly of the test device 100' from the second connecting arm 320b. During the process of the driving part 613 flipping from the position where the length direction of the driving part 613 is parallel to the length direction of the connecting rod 611 to the position where the length direction of the driving part 613 is perpendicular to the length direction of the connecting rod 611, the driving part 613 drives the connecting rod 611 and the locking part 612 sleeved on the connecting rod 611 to rise along the height direction Z, so that the locking part 612 abuts against the connecting plate 80 and the hole wall 3231, so that the connecting plate 80 is locked in the through hole 3230 of the second connecting arm 320b through the locking part 612, realizing the assembly of the test device 100' and the second connecting arm 320b. Thus, through the setting of the driving part 613, the rapid disassembly and assembly between the test device 100' and the second connecting arm 320b are realized.

[0128] In some embodiments, referring to Figures 7 to 10 and Figures 13 to 16 , the connecting rod 611 can drive the locking part 612 to move along the width direction Y, so that the locking part 612 can separate from or abut against the hole wall 3231. Specifically, in the embodiments shown in Figures 7 to 10 and Figures 13 to 16 , the number of the second locking parts 61 is two. The two second locking parts 61 are arranged on the connecting plate 80 at intervals along the width direction Y. The locking part 612 extends along the second direction Y. The connecting rod 611 can move on the connecting plate 80 along the width direction Y. Specifically, when a connecting rod 611 drives the locking part 612 to approach another connecting rod 611 along the width direction Y, the locking part 612 can be separated from the hole wall 3231 to release the abutment between the locking part 612 and the hole wall 3231, so as to release the locking of the second locking part 61 on the connection between the connecting plate 80 and the second connecting arm 320b. On the contrary, when a connecting rod 611 drives the locking part 612 to move away from another connecting rod 611 along the width direction Y, the locking part 612 can abut against the hole wall 3231, so that the second locking part 61 resumes the locking of the connection between the connecting plate 80 and the second connecting arm 320b. Thus, the rapid disassembly and assembly between the connecting plate 80 and the second connecting arm 320b are realized.

[0129] In some embodiments, reference Figures 7 to 10 as well as Figures 13 to 16 The connecting rod 611 can drive the locking portion 612 to move along the length direction X, so that the locking portion 612 can be separated from or abutted against the hole wall 3231. Figures 7 to 10 as well as Figures 13 to 16 In the illustrated embodiment, there are three second locking members 61, and the three second locking members 61 are arranged in a herringbone shape on the connecting plate 80 at intervals, wherein two second locking members 61 are arranged on the connecting plate 80 at intervals along the width direction Y, and the locking portions 612 on the two second locking members 61 extend along the width direction Y respectively, and the locking portion 612 of the third second locking member 61 extends along the length direction X. The connecting rod 611 of the third second locking member 61 can move on the connecting plate 80 along the length direction X. Specifically, when the connecting rod 611 of the third second locking member 61 drives the locking portion 612 to approach the third end 323 of the second connecting arm 320b along the length direction X, the locking portion 612 can be separated from the hole wall 3231 to release the abutment between the locking portion 612 and the hole wall 3231, thereby releasing the lock between the connecting plate 80 and the second connecting arm 320b by the third second locking member 61. Conversely, when the connecting rod 611 of the third second locking member 61 drives the locking portion 612 away from the third end 323 along the length direction X, the locking portion 612 can abut against the hole wall 3231, thereby allowing the third second locking member 61 to resume locking between the connecting plate 80 and the second connecting arm 320b, thereby achieving quick disassembly and assembly between the connecting plate 80 and the second connecting arm 320b.

[0130] Moreover, the structural design of the three second locking members 61 arranged in a herringbone shape can achieve locking between the connecting plate 80 and the second connecting arm 320b in three dimensions: the length direction X, the width direction Y, and the height direction Z, thereby ensuring the stability of the connection between the connecting plate 80 and the second connecting arm 320b, ensuring the stability of the rotation of the second connecting arm 320b driven by the testing device 100', ensuring the accuracy of the data collected by the first collecting member 20 and the second collecting member 30, and thus ensuring the accuracy of the test results.

[0131] In some embodiments, reference Figure 14 and Figure 15 The locking portion 612 abuts against the hole wall 3231 , which means that the locking portion 612 abuts against the end surface of the hole wall 3231 along the height direction Z away from the end of the connecting plate 80 .

[0132] In some embodiments, reference Figures 7 to 11 as well as Figure 15 The connecting plate 80 is provided with a protruding portion 81 on one side away from the second main body 10b along the height direction Z. Figure 9 、 Figure 11 as well asFigure 15 , a groove 810 is formed in the convex portion 81, and the groove 810 extends along the width direction Y. Refer to Figure 9 and Figure 15 , the locking portion 612 is embedded in the groove 810. Specifically, in the embodiments shown in Figure 9 and Figure 15 , the locking portion 612 extending along the width direction Y is embedded in the groove 810, and the connecting rod 611 can drive the locking portion 612 to move in the groove 810 along the width direction Y, so as to realize the locking or disassembly between the connecting plate 80 and the second connecting arm 320b. The arrangement of the groove 810 can form a guide for the movement of the locking portion 612 along the width direction Y, thereby ensuring the stability of the abutment or separation between the locking portion 612 and the hole wall 3231.

[0133] In some embodiments, refer to Figure 12 , a recess 6121 is provided on the locking portion 612. The arrangement of the recess 6121 enables a snap connection between the locking portion 612 and the hole wall 3231, thereby ensuring the connection stability between the locking portion 612 and the hole wall 3231 and the locking stability between the connecting plate 80 and the second connecting arm 320b.

[0134] In some embodiments, a transmission plate (not shown in the figure) is connected to the second connecting arm 320b. The transmission plate faces the through hole 3230 along the height direction Z. The transmission plate is pivotally connected to the second connecting arm 320b, and the first connection end 6111 of the connecting rod 611 can abut against the transmission plate. The design of the transmission plate enables the second connecting arm 320b to form a linkage with the first connecting arm 320a. The test device 100' is assembled with the second connecting arm 320b, and the first connection end 6111 of the connecting rod 611 abuts against the transmission plate, causing the transmission plate to turn downwards. The handle 50 drives the second main body 10b to move along the height direction Z, the second main body 10b drives the second connecting arm 320b to rotate, and the second connecting arm 320b drives the first connecting arm 320a through the transmission plate, thereby realizing the opening or closing of the hatch 310.

[0135] In some embodiments of the present application, a test method is provided. The test method uses the test device 100' described above for testing. The test method includes the following steps:

[0136] S1': Connect the second main body 10b to the second connecting arm 320b.

[0137] Specifically, cover the connecting plate 80 on the through hole 3230 of the second connecting arm 320b. Flip the driving part 613 from the position where the length direction of the driving part 613 is parallel to the length direction of the connecting rod 611 to the position where the length direction of the driving part 613 is perpendicular to the length direction of the connecting rod 611. The driving part 613 drives the connecting rod 611 and the locking part 612 sleeved on the connecting rod 611 to rise along the height direction Z, so that the locking part 612 abuts against the connecting plate 80 and the hole wall 3231. The connecting plate 80 is locked in the through hole 3230 of the second connecting arm 320b through the locking part 612, so that the second main body 10b is connected to the second connecting arm 320b through the connecting plate 80, realizing the assembly of the testing device 100' and the second connecting arm 320b.

[0138] S2'. Move the second main body 10b along the height direction Z to drive the second connecting arm 320b to rotate to open or close the hatch 310.

[0139] Specifically, the operator holds the handle 50 and drives the handle 50 to move along the height direction Z. The handle 50 drives the second main body 10b to move along the height direction Z through the second frame 71. The second main body 10b drives the second connecting arm 320b to rotate through the connecting plate 80. Among them, the operator applies an upward pulling force to the handle 50 to drive the second main body 10b to rise along the height direction Z, and the second main body 10b drives the second connecting arm 320b to rotate to open the hatch 310; the operator applies a downward pressing force to the handle 50 to drive the second main body 10b to descend along the height direction Z, and the second main body 10b drives the second connecting arm 320b to rotate to close the hatch 310.

[0140] S3'. Analyze the force data collected by the first acquisition part 20 and the angle data collected by the second acquisition part 30 through the data acquisition unit 40, and output the force and angle test curves through the data acquisition unit 40. Among them, the force and angle test curves include the force and angle test curves during the process of the second connecting arm 320b driving the hatch 310 to open, and the force and angle test curves during the process of the second connecting arm 320b driving the hatch 310 to close.

[0141] Specifically, collect the operating force applied by the operator on the handle 50 for driving the second connecting arm 320b to rotate through the first acquisition part 20. The first acquisition part 20 transmits the collected force data to the data acquisition unit 40. Collect the rotation angle during the process of the second main body 10b driving the second connecting arm 320b to rotate through the second acquisition part 30. The second acquisition part 30 transmits the collected angle data to the data acquisition unit 40. The data acquisition unit 40 analyzes the force data and the angle data and outputs the force and angle test curves.

[0142] In some embodiments, the testing method further includes:

[0143] S4’. Compare the force and angle test curve obtained in step S3 with the pre-stored force and angle standard curve in the data acquisition unit 40 through the data acquisition unit 40. Then, adjust the second connecting arm 320b and the hatch 310 according to the comparison result, so that the operating force for opening or closing the hatch 310 meets the standard value, ensuring the reliability and safety of opening or closing the hatch. Among them, during the process of driving the second connecting arm 320b to rotate to drive the hatch 310 to open or close, there are multiple nodes, and the adjustment of the second connecting arm 320b and the hatch 310 can be achieved by adjusting these multiple nodes. For example, these multiple nodes include, but are not limited to, the contact between the latch and the latch groove, the seal on the hatch 310 reaching the maximum compression amount, and the seal disengaging from the seal stop.

[0144] Among them, Figure 18 In the figure, the solid line shows the force and angle standard curve during the opening process of the hatch 310. Specifically, the standard curve shown by the solid line is the force and angle standard curve during the process of the test device 100 driving the hatch 310 to open through the first connecting arm 320a, or the standard curve shown by the solid line is the force and angle standard curve during the process of the test device 100' driving the hatch to open through the second connecting arm 320b.

[0145] Figure 18 In the figure, the dashed line shows the force and angle standard curve during the closing process of the hatch 310. Specifically, the standard curve shown by the dashed line is the force and angle standard curve during the process of the test device 100 driving the hatch 310 to close through the first connecting arm 320a, or the standard curve shown by the dashed line is the force and angle standard curve during the process of the test device 100' driving the hatch to close through the second connecting arm 320b.

[0146] The data acquisition unit 40 analyzes the force data and the angle data collected by the first acquisition component 20 and the second acquisition component 30, and outputs a force and angle test curve. The data acquisition unit 40 compares the force and angle test curve with Figure 18 the shown force and angle standard curve, and the deviation between the force and angle test curve and the force and angle standard curve can be obtained. Then, according to the nodes corresponding to the deviation, the structure corresponding to the nodes is adjusted and improved, so that the operating force for opening or closing the hatch 310 meets the standard value, ensuring the reliability and safety of opening or closing the hatch.
