Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an anti-thrust test device and an anti-thrust test method. Background Art

[0002] For some foldable devices, such as tablet leather cases, tablet leather case keyboards, foldable mobile phones and laptops, foldable devices usually need to hover after opening the two parts to a certain angle, and be able to maintain a stable hovering state after unloading the force. The hovering stability of foldable devices is very important for the user experience. The current hovering state anti-thrust test is performed by manually holding a thrust gauge and manually guessing the test point. When the angle between the two parts is manually sensed to change, the anti-thrust value is quickly recorded. However, the anti-thrust value obtained by this method has a large error problem. Summary of the invention

[0003] The embodiments of the present application provide an anti-thrust test device and an anti-thrust test method, which are used to solve the problem that the anti-thrust value obtained by a manual handheld thrust meter has a large error.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] In a first aspect, a thrust resistance test device is provided. The thrust resistance test device is used to perform thrust resistance test on a device to be tested, and the device to be tested has a test plane. The thrust resistance test device includes a workbench, a measuring device, a test swing arm, and a driving device. The workbench has a supporting plane. The measuring device is used to measure the angle between the test plane and the supporting plane. The test swing arm is arranged on the supporting plane. The test swing arm can rotate relative to the supporting plane, and the first end of the test swing arm is used as the rotation center, and the second end of the test swing arm rotates around the first end of the test swing arm, and the second end of the test swing arm can abut against the test plane. The output end of the driving device is connected to the test swing arm.

[0006] Based on the above structure, the thrust resistance test device can test whether the thrust resistance of the device to be tested is qualified and measure the maximum thrust resistance of the device to be tested. Compared with the solution of applying thrust by a handheld thrust meter, this solution drives the test swing arm to rotate through a driving device, which can more accurately control the thrust and obtain more accurate test results. In addition, it can realize automated testing, which is conducive to achieving consistency in the test process and improving test efficiency.

[0007] In a possible implementation of the first aspect, the rotation axis of the test swing arm is parallel to the test plane and perpendicular to a connection line between the first end and the second end of the test swing arm.

[0008] If the rotation axis of the test swing arm intersects the test plane, there is a component force in the thrust applied by the test swing arm on the test plane. The force of the test swing arm is not fully used to push the test plane, and some force is lost. Therefore, the test result of the thrust resistance value of the equipment to be tested has low accuracy.

[0009] Therefore, by setting the rotation axis of the test swing arm to be parallel to the test plane, almost all the force of the test swing arm can be used to push the test plane, reducing losses and improving the accuracy of the test results of the anti-thrust test device.

[0010] In a possible implementation of the first aspect, the anti-thrust test device also includes a rotating rod, which can rotate relative to the supporting plane, the first end of the test swing arm is slidably connected to the rotating rod, and the sliding direction of the test swing arm relative to the rotating rod is parallel to the length direction of the rotating rod; the rotating rod is connected between the test swing arm and the output end of the driving device.

[0011] The test swing arm can slide relative to the rotating rod along the length direction of the rotating rod, so that the test swing arm can push different positions of the test plane for testing, obtain multiple sets of test data, improve the reliability of the test results, and make the use of the test swing arm more flexible and convenient.

[0012] In a possible implementation manner of the first aspect, the test swing arm can be extended and retracted along a first direction, and the first direction is a length direction of the test swing arm.

[0013] The length of the test swing arm can be changed, and the test swing arm can be extended or shortened to achieve the test swing arm abutting against the test plane at different positions, so that multiple sets of test data can be obtained, the reliability of the test results is improved, and the flexibility of use of the test swing arm is improved.

[0014] In a possible implementation of the first aspect, the anti-thrust test device further includes a displacement sensor, which is disposed on the test swing arm and is used to measure the distance between the second end of the test swing arm and the test plane.

[0015] When the displacement sensor measures that the vertical distance between the second end of the test swing arm and the test plane is less than or equal to the preset distance, the position of the second end of the test swing arm stops changing, that is, the test swing arm no longer moves, and the test preparation is completed. Setting the displacement sensor is beneficial to achieving consistency in the test process and realizing automated testing.

[0016] In a possible implementation manner of the first aspect, the displacement sensor is slidably connected to the test swing arm, and the displacement sensor can slide along the length direction of the test swing arm.

[0017] Under this structure, the relative position of the displacement sensor and the test swing arm can be flexibly adjusted according to actual needs, thereby improving the flexibility of use of the displacement sensor and enabling the displacement sensor to adapt to more test scenarios.

[0018] In a possible implementation of the first aspect, the anti-thrust test device further includes a support frame, the support frame is disposed on the workbench, and the test swing arm is rotatably connected to the support frame. The support frame supports the test swing arm, so that the structure of the anti-thrust test device is more stable.

[0019] In a possible implementation of the first aspect, the support frame includes a first support rod and a second support rod connected to the workbench, and the test swing arm is rotatably connected between the first support rod and the second support rod. The first support rod, the second support rod and the test swing arm together form a stable frame structure to improve the structural stability of the anti-thrust test device.

[0020] In a possible implementation manner of the first aspect, the support plane, the first support rod, the second support rod, and the test swing arm enclose an avoidance space.

[0021] The avoidance space can be used to avoid the device to be tested, so as to prevent the test swing arm, the first support rod and the second support rod from interfering with or obstructing the device to be tested.

[0022] In a possible implementation manner of the first aspect, the driving device is fixed on the first support rod or the second support rod.

[0023] The driving device can be detachably connected to the first support rod or the second support rod through a fastener, and the fastener can be a bolt, which has the advantages of being easy to obtain and easy to install. In addition, the detachable connection method is convenient for replacing the driving device after it is worn, and is also convenient for replacing driving devices of different powers according to different devices to be tested, making the use of the driving device more flexible and convenient.

[0024] In a possible implementation of the first aspect, the anti-thrust test device also includes a driving mechanism, which is used to drive the support frame to move along a second direction, the second direction is a distribution direction of the test swing arm and the equipment to be tested, and the second direction is parallel to the support plane.

[0025] The driving mechanism can drive the second support rod to move along the second direction, and the second support rod drives the test swing arm to move along the second direction, so that the position of the test swing arm along the second direction can be flexibly adjusted according to the position of the test plane, thereby improving the flexibility of use of the test swing arm.

[0026] In a possible implementation of the first aspect, the driving mechanism includes a driving motor, a lead screw and a connecting block. The driving motor is arranged on a workbench, the output end of the driving motor is connected to the lead screw, the lead screw is threadedly connected to the connecting block, the lead screw is arranged along the second direction, and the connecting block is connected to the support frame.

[0027] The driving motor drives the lead screw to rotate, the lead screw rotation drives the connection block to move along the second direction, the connection block drives the support frame to move, the support frame drives the test swing arm to move along the second direction, so that the position of the test swing arm along the second direction can be changed. Under this structure, the transmission is carried out through the lead screw, and the transmission accuracy is high and the stability is good. The lead screw is threadedly connected to the connection block, and the threaded connection can achieve self-locking, so that the lead screw and the connection block have a high connection stability.

[0028] In a possible implementation of the first aspect, the measuring device is a binocular vision system. In the measurement of moving objects, since the image acquisition of the binocular vision system is completed instantly, the binocular vision system is a more accurate measurement structure compared to an angle ruler, and can accurately measure the tilt angle of the test plane.

[0029] In a second aspect, a thrust resistance test method is also provided, which is used to perform a thrust resistance test on a device to be tested, wherein the device to be tested has a test plane.

[0030] Thrust test methods include:

[0031] Measure the initial angle between the support plane of the table and the test plane;

[0032] Make the distance between the second end of the test swing arm and the test plane less than or equal to a preset distance;

[0033] The test swing arm is driven to rotate by a driving device so that the test swing arm abuts against the test plane.

[0034] After the test swing arm contacts the test plane, the driving device can continue to drive the test swing arm to rotate, so that the test swing arm applies thrust to the device to be tested, so that the test plane rotates relative to the supporting plane, thereby testing the thrust resistance of the device to be tested. Compared with the solution of applying thrust by a handheld thrust gauge, this solution drives the test swing arm to rotate by the driving device, which can control the thrust more accurately and obtain more accurate test results. In addition, it can realize automated testing and improve test efficiency.

[0035] In a possible implementation of the second aspect, when the distance between the second end of the test swing arm and the test plane is less than or equal to a preset distance, the test swing arm is parallel to the test plane, so that almost all the force of the test swing arm is used to push the test plane, reducing losses, and improving the accuracy of the test results.

[0036] In a possible implementation manner of the second aspect, after the test swing arm abuts against the test plane, the thrust resistance test method further includes:

[0037] The driving device drives the test swing arm to continue to rotate, so that the test swing arm pushes the device to be tested to rotate;

[0038] Measuring the test angle between the support plane and the test plane;

[0039] The angle difference between the test angle and the initial angle is calculated; when the angle difference is less than or equal to the preset angle, the test is passed; when the angle difference is greater than the preset angle, the test is failed.

[0040] A preset torque can be set for the test swing arm, and when the test swing arm rotates to reach the preset torque, the driving device stops driving the test swing arm to rotate. The test angle between the support plane and the test plane can be measured by a measuring device. The test state may refer to a state in which the test swing arm stops pushing the test plane. When the angle difference between the test angle and the initial angle is less than or equal to the preset angle, the test is qualified, indicating that the device to be tested can remain stable under the action of the preset torque. When the angle difference between the test angle and the initial angle is greater than the preset angle, the test fails, indicating that the device to be tested cannot remain stable under the action of the preset torque, there is a large angle change, and the hovering stability is low, and the device to be tested needs to be further improved.

[0041] In a possible implementation manner of the second aspect, a method for measuring an initial angle between a support plane of a workbench and a test plane includes:

[0042] Acquire at least three first positioning points on the test plane by a measuring device to determine the position of the test plane;

[0043] Acquire at least three second positioning points on the support plane by a measuring device to determine the position of the support plane;

[0044] The measuring device obtains an initial angle between the test plane and the support plane according to the position of the test plane and the position of the support plane.

[0045] The normal vector of the test plane obtained according to the coordinates of at least three first positioning points is m1, the normal vector of the support plane obtained according to the coordinates of at least three second positioning points is n1, and the initial angle between the test plane and the support plane is γ1. γ1 can be calculated according to the formula: cosγ1=<n1, m1>.

[0046] In a possible implementation manner of the second aspect, a method for making the distance between the test swing arm and the test plane less than or equal to a preset distance includes:

[0047] Set the marking points on the test plane;

[0048] Move the test swing arm or the device to be tested so that the distance between the second end of the test swing arm and the marking point is less than or equal to the preset distance.

[0049] By setting marking points, operators can more quickly confirm the relative position of the test swing arm and the device to be tested, thereby improving work efficiency.

[0050] In a possible implementation manner of the second aspect, the marking point is a center point of a geometric figure formed by sequentially connecting at least three first positioning points.

[0051] When the test swing arm pushes the test plane, the measuring device will obtain the instantaneous position of the test plane and the supporting plane. The test plane will rotate relative to the supporting plane, and the force exerted by the test swing arm on both sides of the test plane is different. If the distance between the marking point and the first positioning point is too far, the error of the test plane obtained by the measuring device may be large, resulting in a large error in the angle between the test plane and the supporting plane. Therefore, the marking point is the center point of the geometric figure formed by connecting the three first positioning points in sequence, so that the marking point is always located in the plane formed by the three first positioning points, the error of the test plane obtained by the measuring device is small, and the angle error between the test plane and the supporting plane is small, thereby improving the accuracy of the test results.

DETAILED DESCRIPTION

[0069] In the embodiments of the present application, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0070] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0071] The embodiment of the present application provides an anti-thrust test device, which is used to perform an anti-thrust test on a device to be tested. The device to be tested may be a foldable mobile phone, a foldable tablet computer (tablet personal computer), a tablet computer with a protective cover, a tablet computer with a leather case keyboard, a foldable game console, a laptop computer, or other foldable devices. For the convenience of explanation, the following examples are all taken as an example of a tablet computer with a leather case keyboard as the device to be tested.

[0072] See also Figure 1 , Figure 1 The structure diagram of a device under test 200 provided in an embodiment of the present application. The device under test 200 may include a device body 201 and a keyboard part 202, and the device body 201 may rotate relative to the keyboard part 202. With the rotation, the form of the device under test 200 may switch between a folded state and a hovering state.

[0073] For the convenience of the following description, an XYZ coordinate system is established, and the width direction of the keyboard part 202 in the device to be tested 200 is defined as the X-axis direction, the length direction of the keyboard part 202 is defined as the Y-axis direction, and the thickness direction of the keyboard part 202 is defined as the Z-axis direction. It can be understood that Figure 1 Only some components of the device to be tested 200 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 restrictions.

[0074] For the convenience of description, the holes, grooves, holes, etc. in the drawings that represent spatial features are marked with arrowheads, and the features that represent physical structures are marked with arrowheads.

[0075] The device body 201 may include a test plane 203, which is a side of the device body 201 close to the keyboard part 202. The keyboard part 202 may include a reference plane 204, which is a side of the keyboard part 202 close to the device body 201.

[0076] When the device to be tested 200 is in the folded state, the test plane 203 and the reference plane 204 are arranged opposite to each other, that is, the test plane 203 and the reference plane 204 are parallel or approximately parallel.

[0077] When the device to be tested 200 is in a hovering state, the angle between the test plane 203 and the reference plane 204 can be 90°, 100°, 110°, 120°, 130°, 140°, 150° or 160°. The angle between the test plane 203 and the reference plane 204 can be adjusted by rotating the device body 201. When the device to be tested 200 is in a hovering state, the test plane 203 and the reference plane 204 can be fully exposed to the user, so as to facilitate human-computer interaction.

[0078] The device to be tested 200 needs to be able to stably maintain a hovering state, and the hovering stability of the device to be tested 200 is very important for the user experience. In order to measure the anti-thrust force of the device to be tested 200 in a hovering state, the relevant technology usually uses a thrust meter 300 to measure. The operator holds the thrust meter 300 and manually applies thrust to push the test plane 203. When the operator senses that the angle between the test plane 203 and the reference plane 204 has changed, the anti-thrust force value on the thrust meter 300 is quickly recorded.

[0079] See also Figure 2 , Figure 2 The present invention provides a schematic diagram of a connection structure between a device under test 200 and an angle ruler 400. It is understandable that the angle ruler 400 can be installed on the side of the device under test 200 to measure the angle between the test plane 203 and the reference plane 204.

[0080] However, the above-mentioned solution of manually holding the thrust meter 300 to measure the anti-thrust force has the problem of large error.

[0081] To solve the above problems, the present application provides an anti-thrust test device 100. Figure 3 , Figure 3The present invention provides a schematic structural diagram of a thrust test device 100 provided in an embodiment of the present invention. The thrust test device 100 includes a workbench 10, a measuring device 20, a test swing arm 30, and a driving device 40. The workbench 10 is an approximately rectangular plate-shaped structure, and the workbench 10 has a support plane 11, and the support plane 11 can extend along the XY plane. The device to be tested 200 can be placed on the support plane 11, and the support plane 11 is parallel to the reference plane 204.

[0082] Exemplarily, an alignment line 13 may be provided on the support plane 11 . The alignment line 13 is used to locate the placement position of the device to be tested 200 . The edge of the device to be tested 200 may be aligned with the alignment line 13 .

[0083] The measuring device 20 is used to measure the angle between the test plane 203 and the support plane 11. The measuring device 20 can be a binocular vision system, and the binocular vision system adopts binocular stereo vision technology. Binocular stereo vision is an important form of machine vision. Binocular stereo vision is based on the principle of parallax and uses imaging devices (such as cameras) to obtain two images of the object to be measured from different positions, and obtains the three-dimensional geometric information of the object to be measured by calculating the position deviation between the corresponding points of the object to be measured in the two images. The user can measure the moving object based on the binocular stereo vision technology and use kinematic parameters to describe the movement of the object, for example, using kinematic parameters such as displacement, velocity, acceleration, angular velocity and angular acceleration. In the measurement of moving objects, since the image acquisition of the binocular vision system is completed in an instant, the binocular vision system is compared with the angle ruler 400 (see Figure 2 ) is a more accurate measurement structure, which can accurately measure the tilt angle of the test plane 203 during the rotation process and analyze the rotation process of the test plane 203.

[0084] The test swing arm 30 is disposed on the support plane 11. The test swing arm 30 can rotate relative to the support plane 11, and with the first end 31 of the test swing arm 30 as the rotation center, the second end 32 of the test swing arm 30 can rotate around the first end 31 of the test swing arm 30, so that the second end 32 of the test swing arm 30 can abut against the test plane 203.

[0085] The rotation axis of the test swing arm 30 is parallel to the test plane 203. The rotation axis of the test swing arm 30 is perpendicular to the connection line between the first end 31 and the second end 32 of the test swing arm 30. If the rotation axis of the test swing arm 30 intersects with the test plane 203, the thrust applied by the test swing arm 30 on the test plane 203 has a component force, and the force of the test swing arm 30 is not fully used to push the test plane 203, and there is a part of loss, and the test result accuracy of the thrust resistance value of the device to be tested 200 is low. Therefore, setting the rotation axis of the test swing arm 30 to be parallel to the test plane 203 can improve the test result accuracy of the thrust resistance test device 100.

[0086] The output end of the driving device 40 is connected to the test swing arm 30. Exemplarily, the driving device 40 may be a motor, which has the advantages of high output accuracy and high transmission efficiency, and can improve the accuracy of the test result.

[0087] The thrust resistance test device 100 in the embodiment of the present application can test whether the thrust resistance of the device to be tested 200 is qualified. First, the initial angle between the support plane 11 and the test plane 203 is measured by the measuring device 20, so that the vertical distance between the second end 32 of the test swing arm 30 and the test plane 203 is less than or equal to the preset distance, for example, the preset distance can be 1mm. Then the test swing arm 30 is driven to rotate by the driving device 40, so that the test swing arm 30 abuts against the test plane 203. The driving device 40 drives the test swing arm 30 to continue to rotate, so that the second end 32 of the test swing arm 30 applies thrust to the test plane 203, and the second end 32 of the test swing arm 30 pushes the test plane 203 to rotate relative to the support plane 11. When the test swing arm 30 rotates to reach the preset torque value, the driving device 40 stops driving the test swing arm 30 to rotate, and the measuring device 20 measures the test angle between the support plane 11 and the test plane 203, and then calculates the angle difference between the test angle and the initial angle. When the angle difference is less than or equal to the preset angle, for example, the preset angle may be 2°, the test is qualified, indicating that the device 200 to be tested can remain stable under the action of the preset torque. When the angle difference is greater than the preset angle, the test is unqualified, indicating that the device 200 to be tested cannot remain stable under the action of the preset torque, has a large angle change, and has low hovering stability, and further improvements are needed to the device 200 to be tested.

[0088] It can be understood that the driving device 40 drives the test swing arm 30 to rotate to reach a preset torque T. The length of the test swing arm 30, that is, the lever arm, is L. According to the formula T=FL, the thrust F of the test swing arm 30 can be obtained.

[0089] The thrust resistance test device 100 can also measure the maximum thrust resistance of the device to be tested 200. The test swing arm 30 is driven to rotate by the driving device 40 so that the test swing arm 30 abuts against the test plane 203. The driving device 40 drives the test swing arm 30 to continue to rotate so that the second end 32 of the test swing arm 30 applies thrust to the test plane 203. The second end 32 of the test swing arm 30 pushes the test plane 203 to rotate relative to the support plane 11 until the device to be tested 200 falls over so that the test plane 203 is parallel to the support plane 11. The maximum torque T of the second end 32 of the test swing arm 30 is recorded. max , according to T max Calculate the maximum thrust F max , the maximum thrust F max That is, the maximum thrust resistance of the device 200 to be tested.

[0090] Based on the above structure, the thrust resistance test device 100 can test whether the thrust resistance of the device to be tested 200 is qualified and measure the maximum thrust resistance of the device to be tested 200. Figure 1 ) The scheme of applying thrust, this scheme drives the test swing arm 30 to rotate by the driving device 40, can more accurately control the thrust and obtain more accurate test results. In addition, it can realize automated testing, which is conducive to achieving consistency of the test process and improving test efficiency.

[0091] In some embodiments, please refer to Figure 3 The anti-thrust test device 100 may further include a rotating rod 50, which can rotate relative to the support plane 11. The rotating rod 50 is connected between the test swing arm 30 and the output end of the driving device 40, and the driving device 40 can drive the rotating rod 50 to rotate, and the rotating rod 50 can drive the test swing arm 30 to rotate.

[0092] The first end 31 of the test swing arm 30 is slidably connected to the rotating rod 50, and the sliding direction of the test swing arm 30 relative to the rotating rod 50 is parallel to the length direction of the rotating rod 50. The length direction of the rotating rod 50 is the Y-axis direction, and the test swing arm 30 can slide along the Y-axis direction relative to the rotating rod 50, so that the test swing arm 30 can push the test plane 203 to different positions along the Y-axis direction for testing, and obtain multiple groups of test results, so that the use of the test swing arm 30 is more flexible and convenient.

[0093] For example, please refer to Figure 3 and Figure 4 , Figure 4A cross-sectional schematic diagram of a test swing arm 30 and a rotating rod 50 provided in an embodiment of the present application. The anti-thrust test device 100 further includes a sliding sleeve 37, which extends along the Y-axis direction, is connected to the second end 32 of the test swing arm 30, and is sleeved on the rotating rod 50. The sliding sleeve 37 can slide along the Y-axis direction relative to the rotating rod 50, so that the sliding sleeve 37 drives the second end 32 of the test swing arm 30 to slide along the Y-axis direction, that is, the first end 31 of the test swing arm 30 can slide along the Y-axis direction.

[0094] Based on this, the thrust resistance test device 100 may further include an adjusting knob 38, and the sliding sleeve 37 is provided with a connecting hole 371, and the connecting hole 371 penetrates the sliding sleeve 37 in the radial direction of the sliding sleeve 37. The adjusting knob 38 passes through the connecting hole 371, and the adjusting knob 38 can abut against the rotating rod 50 to achieve the position fixation of the sliding sleeve 37. An internal thread may be provided in the connecting hole 371, and an external thread may be provided on the adjusting knob 38. The adjusting knob 38 is threadedly connected to the hole wall of the connecting hole 371, and the adjusting knob 38 abuts against the rotating rod 50 by screwing the adjusting knob 38, and the threaded connection can achieve self-locking, so that the connection between the adjusting knob 38 and the rotating rod 50 is stable and reliable.

[0095] For example, see Figure 5 , Figure 5 A schematic diagram of the connection structure of a test swing arm 30 and a rotating rod 50 provided in an embodiment of the present application. A first slider 311 is provided at the first end 31 of the test swing arm 30, and a slide groove 312 extending along the Y-axis direction is provided on the first slider 311. A first slide rail 51 is provided on the rotating rod 50, and the first slide rail 51 can extend along the Y-axis direction. The first slide rail 51 is located in the slide groove 312, and the first slide rail 51 can slide along the Y-axis direction relative to the groove wall of the slide groove 312. The cooperation between the first slider 311 and the first slide rail 51 enables the test swing arm 30 to stably and reliably slide along the Y-axis direction relative to the rotating rod.

[0096] It is understandable that, for fixing the relative positions of the first sliding block 311 and the first sliding rail 51, reference may be made to the above Figure 4 A plurality of jacks may be provided on the first slide rail 51, the plurality of jacks being distributed along the Y-axis direction, and a latch is provided to pass through the first slider 311 and any one of the jacks to fix the relative position of the first slider 311 and the first slide rail 51.

[0097] In some embodiments, see Figure 6 , Figure 6The present invention provides a schematic diagram of the structure of a test swing arm 30 provided in an embodiment of the present invention. The test swing arm 30 can be extended and retracted along a first direction, and the first direction is the length direction of the test swing arm 30. In other words, the length of the test swing arm 30 can be changed, and the test swing arm 30 can be extended or shortened to achieve the test swing arm 30 abutting against different positions of the test plane 203, thereby improving the use flexibility of the test swing arm 30.

[0098] For example, Figure 6 As shown, the test swing arm 30 may include a first sleeve 35 and a second sleeve 36. The first sleeve 35 and the second sleeve 36 both extend along the first direction. The first sleeve 35 is sleeved on the second sleeve 36. The first sleeve 35 can slide along the first direction relative to the outer wall of the second sleeve 36 to change the overall length of the test swing arm 30 along the first direction.

[0099] It is understandable that an elastic buckle can be provided on the second sleeve 36 , and multiple clip holes can be opened on the first sleeve 35 , the multiple clip holes are distributed along the first direction, and the elastic buckle is inserted into any one of the clip holes to fix the relative position of the first sleeve 35 and the second sleeve 36 .

[0100] For example, see Figure 7 , Figure 7 Schematic diagram of another test swing arm 30 provided in an embodiment of the present application. The test swing arm 30 may include a first swing arm 33, a second swing arm 34, a second slider 331 and a second slide rail 341. The first swing arm 33 and the second swing arm 34 both extend along a first direction. The second slider 331 may be disposed on one of the first swing arm 33 and the second swing arm 34, and the second slide rail 341 may be disposed on the other of the first swing arm 33 and the second swing arm 34. Figure 7 As shown, the second slider 331 is disposed on the first swing arm 33, the second slide rail 341 is disposed on the second swing arm 34, and the second slide rail 341 extends along the first direction. It can be understood that the second slider 331 can be connected to the first slider 311 (see Figure 5 ) is similar in structure, the second slide rail 341 can be connected to the first slide rail 51 (see Figure 5 The second slider 331 can slide relative to the second slide rail 341 to enable the first swing arm 33 to slide relative to the second swing arm 34 along the first direction to change the overall length of the test swing arm 30 along the first direction.

[0101] It is understandable that the manner in which the relative positions of the second slider 331 and the second slide rail 341 are fixed may refer to the above-mentioned first slider 311 and the first slide rail 51 .

[0102] In some embodiments, see Figure 8 , Figure 8The structural diagram of another anti-thrust test device 100 provided in an embodiment of the present application is shown. The anti-thrust test device 100 further includes a support frame 70, which is disposed on a workbench 10, and a test swing arm 30 is rotatably connected to the support frame 70. The test swing arm 30 can rotate relative to the support frame 70, and the support frame 70 supports the test swing arm 30, so that the structure of the anti-thrust test device 100 is more stable.

[0103] On this basis, the support frame 70 includes a first support rod 71 and a second support rod 72, both of which are connected to the workbench 10, and both of which extend along the Z-axis direction, and the first support rod 71 and the second support rod 72 are distributed along the Y-axis direction. The test swing arm 30 is rotatably connected between the first support rod 71 and the second support rod 72, and the test swing arm 30 can rotate relative to the first support rod 71 and the second support rod 72. The first support rod 71, the second support rod 72 and the test swing arm 30 together form a stable frame structure, which improves the structural stability and reliability of the anti-thrust test device 100.

[0104] The support plane 11, the first support rod 71, the second support rod 72 and the test swing arm 30 enclose an avoidance space 73. The reference plane 204 of the device to be tested 200 can be located in the avoidance space 73. The avoidance space 73 can avoid the reference plane 204 of the device to be tested 200 to prevent the test swing arm 30, the first support rod 71 and the second support rod 72 from interfering with or obstructing the device to be tested 200.

[0105] The driving device 40 is fixed on the first support rod 71, or Figure 8 As shown, the driving device 40 is fixed on the second support rod 72. Exemplarily, the driving device 40 can be detachably connected to the first support rod 71 or the second support rod 72 by a fastener, and the fastener can be a bolt, which has the advantages of easy material acquisition and convenient installation. In addition, the detachable connection method is convenient for replacing the driving device 40 after wear, and is also convenient for replacing driving devices 40 of different powers according to different devices 200 to be tested, making the use of the driving device 40 more flexible and convenient.

[0106] In some embodiments, please refer to Figure 8 The thrust resistance testing device 100 may further include a driving mechanism 80, which is used to drive the support frame 70 to move along a second direction. The second direction is the distribution direction of the test swing arm 30 and the device to be tested 200, and the second direction is parallel to the supporting plane 11, that is, the second direction is the X-axis direction.

[0107] like Figure 8As shown, the driving mechanism 80 can drive the second support rod 72 to move along the X-axis direction, and the second support rod 72 drives the test swing arm 30 to move along the X-axis direction, so that the position of the test swing arm 30 along the X-axis direction can be flexibly adjusted according to the position of the test plane 203, thereby obtaining multiple sets of test data and improving the flexibility of use of the test swing arm 30.

[0108] On this basis, please refer to Figure 8 and Fig. 9 , Fig. 9 A schematic diagram of the connection structure between the drive mechanism 80 and the second support rod 72 in a thrust resistance test device 100 provided in an embodiment of the present application. The drive mechanism 80 includes a drive motor 81, a lead screw 82 and a connecting block 83. The drive motor 81 is disposed on the workbench 10, and the output end of the drive motor 81 is connected to the lead screw 82. The drive motor 81 serves as a power source, and the drive motor 81 can drive the lead screw 82 to rotate. The motor has the advantages of high output accuracy and high transmission efficiency.

[0109] The lead screw 82 is arranged along the second direction, that is, the lead screw 82 extends along the X-axis direction. The lead screw 82 is threadedly connected to the connecting block 83 , and the connecting block 83 is connected to the second support rod 72 .

[0110] The driving motor 81 can drive the lead screw 82 to rotate, the lead screw 82 rotates to drive the connecting block 83 to move along the X-axis direction, the connecting block 83 drives the support frame 70 to move, and the support frame 70 drives the test swing arm 30 to move along the X-axis direction, so that the position of the test swing arm 30 along the X-axis direction can be changed. Under this structure, the lead screw 82 is threadedly connected to the connecting block 83, and the threaded connection can achieve self-locking, so that the lead screw 82 and the connecting block 83 have a high connection stability. In addition, the transmission is carried out through the lead screw 82, and the transmission accuracy is high and the stability is good.

[0111] The driving mechanism 80 may further include a mounting base 84, and the mounting base 84 includes a first mounting plate 841, a second mounting plate 842, and a third mounting plate 843. The first mounting plate 841 is connected to the workbench 10, and the second mounting plate 842 and the third mounting plate 843 are both connected to the first mounting plate 841, and the second mounting plate 842 and the third mounting plate 843 are distributed along the X-axis direction. The driving motor 81 can be connected to the second mounting plate 842, or, as Fig. 9 As shown, the drive motor 81 can be connected to the third mounting plate 843. The second mounting plate 842 and the third mounting plate 843 are both provided with mounting holes 844, and the two ends of the lead screw 82 can rotatably pass through the two mounting holes 844 respectively. The hole walls of the two mounting holes 844 can limit the lead screw 82 to prevent the lead screw 82 from shaking in the Y-axis or Z-axis direction, so that the lead screw 82 can rotate more stably and reliably, thereby improving the transmission stability and reliability of the lead screw 82.

[0112] The driving mechanism 80 may further include a guide rod 85, which extends along the X-axis direction, and the two ends of the guide rod 85 are respectively connected to the second mounting plate 842 and the third mounting plate 843. The guide rod 85 passes through the connecting block 83, and the guide rod 85 can guide the movement of the connecting block 83 along the X-axis direction, thereby improving the stability and reliability of the movement of the connecting block 83 along the X-axis direction.

[0113] Exemplarily, the number of guide rods 85 can be two, the two guide rods 85 are distributed along the Y-axis direction, and the two guide rods 85 are respectively located on both sides of the lead screw 82. By providing two guide rods 85 to guide the connecting block 83, the force on the connecting block 83 is more uniform, so that the connecting block 83 can move more stably along the X-axis direction.

[0114] Based on this, please continue to refer to Figure 8 The anti-thrust test device 100 may further include a third slider 711 and a third slide rail 12, wherein the third slider 711 is connected to the first support rod 71. The third slide rail 12 is distributed along the X-axis direction, and the third slider 711 is slidably connected to the third slide rail 12. By arranging the third slider 711 and the third slide rail 12 to cooperate, the movement of the first support rod 71 along the X-axis direction is guided, the movement reliability and stability of the first support rod 71 along the X-axis direction are improved, and the force on both sides of the test swing arm 30 along the Y-axis direction is made more uniform, so that the test swing arm 30 can move more stably and reliably along the X-axis direction.

[0115] It is understandable that the relative position fixing method of the third slider 711 and the third slide rail 12 can refer to the above-mentioned first slider 311 and the first slide rail 51 (see Figure 5 ).

[0116] In some embodiments, please refer to Figure 8 The anti-thrust test device 100 further includes a displacement sensor 60, which is disposed on the test swing arm 30 and is used to measure the vertical distance between the second end 32 of the test swing arm 30 and the test plane 203. When the displacement sensor 60 measures that the vertical distance between the second end 32 of the test swing arm 30 and the test plane 203 is less than or equal to the preset distance, the position of the second end 32 of the test swing arm 30 is stopped from being changed, that is, the test swing arm 30 no longer moves along the Y-axis or X-axis direction, and the test preparation is completed. By setting the displacement sensor 60 to measure the vertical distance between the second end 32 of the test swing arm 30 and the test plane 203 to complete the test preparation, it is beneficial to achieve consistency of the test process and realize automated testing.

[0117] For example, the preset distance may be 1 mm, that is, when the displacement sensor 60 measures that the vertical distance between the second end 32 of the test swing arm 30 and the test plane 203 is less than or equal to 1 mm, the position of the second end 32 of the test swing arm 30 is stopped from being changed.

[0118] Exemplarily, the displacement sensor 60 may be a laser displacement sensor or an ultrasonic displacement sensor, which have higher measurement accuracy.

[0119] On this basis, see Fig.10 , Fig.10 The present invention provides a schematic diagram of the connection structure of the displacement sensor 60 and the test swing arm 30 in an anti-thrust test device 100 provided in an embodiment of the present invention. The displacement sensor 60 is slidably connected to the test swing arm 30, and the displacement sensor 60 can slide along the length direction of the test swing arm 30. The relative position of the displacement sensor 60 and the test swing arm 30 can be flexibly adjusted according to actual needs, thereby improving the flexibility of the use of the displacement sensor 60 and enabling the displacement sensor 60 to adapt to more test scenarios.

[0120] The anti-thrust test device 100 may further include a sliding member 61 and a locking member 62. The sliding member 61 is connected to the displacement sensor 60. The sliding member 61 is provided with a sliding groove 611, which extends along the length direction of the test swing arm 30. The test swing arm 30 is located in the sliding groove 611. The sliding member 61 can slide relative to the test swing arm 30, and the sliding of the sliding member 61 drives the displacement sensor 60 to slide. The locking member 62 passes through the sliding member 61 and is detachably connected to the test swing arm 30. After the displacement sensor 60 slides to the specified position, it is locked by the locking member 62, so that the position of the displacement sensor 60 is fixed.

[0121] Exemplarily, the locking member 62 can be a bolt, and a plurality of threaded holes can be opened on the test swing arm 30, and the plurality of threaded holes are distributed along the length direction of the test swing arm 30. The locking member 62 passes through the sliding member 61 and is threadedly connected to any one of the threaded holes to fix the position of the sliding member 61, thereby fixing the position of the displacement sensor 60.

[0122] Exemplarily, scale lines may be provided on the test swing arm 30 to facilitate calculation of the distance from the displacement sensor 60 to the rotation center to obtain the length of the force arm, thereby making the use of the anti-thrust test device 100 more convenient.

[0123] See also Fig.11 , Fig.11 The present invention also provides a method for testing thrust resistance, which is used to test thrust resistance of a device 200 to be tested.

[0124] Thrust test methods include:

[0125] Step S10, measuring the initial angle between the support plane 11 of the workbench 10 and the test plane 203;

[0126] The initial angle between the support plane 11 and the test plane 203 can be measured by the measuring device 20. The measuring device 20 can be a binocular vision system. The binocular vision system has a certain depth of field range, and the depth of field refers to the distance range of imaging that a camera lens or other imager can obtain a clear image. Before the measuring device 20 measures, it is necessary to confirm that the device to be tested 200 is within the depth of field range so that the measuring device 20 can obtain the test plane 203 of the device to be tested 200.

[0127] Please continue reading Fig.11 , step S10 may include:

[0128] Step S11, obtaining at least three first positioning points 207 on the test plane 203 by the measuring device 20 to determine the position of the test plane 203;

[0129] At least three first positioning blocks can be set on the test plane 203 by bonding, and the position of the first positioning block is the first positioning point 207. The bonding method is convenient for removing the first positioning block from the test plane 203 after the test is completed, so that the first positioning block can be recycled, and the first positioning block will not affect the surface aesthetics of the test plane 203. According to the principle that three points can determine a plane, the measuring device 20 obtains the coordinates of at least three first positioning points 207 on the test plane 203, and can determine the position of the test plane 203, so as to facilitate the subsequent acquisition of the initial angle between the test plane 203 and the support plane 11.

[0130] Exemplarily, the number of the first positioning points 207 on the test plane 203 may also be greater than three, such as four, five, six or other numbers.

[0131] Step S12, obtaining at least three second positioning points 111 on the supporting plane 11 by the measuring device 20 to determine the position of the supporting plane 11;

[0132] Similarly, at least three second positioning blocks can also be set on the support plane 11 by bonding, and the position of the second positioning blocks is the second positioning point 111. When the device to be tested 200 has a reference plane 204, the reference plane 204 of the device to be tested 200 is parallel to the support plane 11, so the angle between the reference plane 204 and the test plane 203 is equal to the angle between the support plane 11 and the test plane 203. In other words, the second positioning point 111 can also be obtained on the reference plane 204 of the device to be tested 200. For the convenience of description below, the second positioning point 111 is located on the reference plane 204 of the device to be tested 200 as an example for description.

[0133] The number of second positioning points 111 is the same as that of first positioning points 207 and they are arranged in one-to-one correspondence. That is, the distance between the second positioning point 111 and the edge of the reference plane 204 along the X-axis direction is equal to the distance between the corresponding first positioning point 207 and the edge of the test plane 203 along the X-axis direction.

[0134] When the test swing arm 30 pushes the test plane 203, the measuring device 20 will obtain the instantaneous position of the test plane 203 and the support plane 11, and obtain the angle between the test plane 203 and the support plane 11 according to the position of the test plane 203 and the position of the support plane 11. If the position of the second positioning point 111 is far away from the position of the first positioning point 207 along the X-axis direction, the angle between the obtained test plane 203 and the support plane 11 may have a large error. Therefore, the second positioning point 111 is set corresponding to the first positioning point 207, which can improve the accuracy of the test result.

[0135] In step S13 , the measuring device 20 obtains an initial angle between the test plane 203 and the support plane 11 according to the position of the test plane 203 and the position of the support plane 11 .

[0136] Please refer to Fig.11 and Fig.12 , Fig.12 A vector diagram of the test plane 203 and the support plane 11 in the initial state provided by the embodiment of the present application. Fig.12 The straight lines with arrows in them represent vectors.

[0137] In the initial state, the normal vector of the test plane 203 obtained according to the coordinates of at least three first positioning points 207 is m1, and the normal vector of the support plane 11 obtained according to the coordinates of at least three second positioning points 111 is n1. The initial angle between the test plane 203 and the support plane 11 is γ1, and γ1 can be calculated according to the formula: cosγ1=<n1, m1>.

[0138] Step S20, making the distance between the second end 32 of the test swing arm 30 and the test plane 203 less than or equal to a preset distance;

[0139] The test swing arm 30 can be moved along the X-axis and Y-axis directions and rotated so that the vertical distance between the second end 32 of the test swing arm 30 and the test plane 203 is less than or equal to a preset distance, which can be 1 mm.

[0140] Please continue reading Fig.11 , step S20 comprises:

[0141] Step S21, setting a marking point 208 on the test plane 203;

[0142] Step S22 , moving the test swing arm 30 or the device to be tested 200 , so that the distance between the second end 32 of the test swing arm 30 and the marking point 208 is less than or equal to a preset distance.

[0143] A marking block can be set on the test plane 203 by bonding, and the position of the marking block is the marking point 208. The bonding is convenient for removing the marking block from the test plane 203 after the test is completed, so that the marking block can be recycled, and the marking block will not affect the surface aesthetics of the test plane 203. Move the position of the test swing arm 30, or move the position of the device to be tested 200, so that the vertical distance between the second end 32 of the test swing arm 30 and the marking point 208 is less than or equal to the preset distance. By setting the marking point 208, the operator can more quickly confirm the relative position of the test swing arm 30 and the device to be tested 200, thereby improving work efficiency.

[0144] On this basis, the marking point 208 is the center point of the geometric figure formed by sequentially connecting at least three first positioning points 207. Exemplarily, when the number of the first positioning points 207 is three, the marking point 208 is the center point of the triangle formed by sequentially connecting the three first positioning points 207. When the number of the first positioning points 207 is four, the marking point 208 is the center point of the quadrilateral formed by sequentially connecting the four first positioning points 207. For the convenience of description, the following example is taken as an example that the number of the first positioning points 207 is three.

[0145] When the test swing arm 30 pushes the test plane 203, the measuring device 20 will obtain the instantaneous position of the test plane 203 and the supporting plane 11, and the test plane 203 will rotate relative to the supporting plane 11, and the force exerted by the test swing arm 30 on the two sides of the test plane 203 along the X-axis direction is different. If the distance between the marking point 208 and the first positioning point 207 along the X-axis direction is too far, the error of the test plane 203 obtained by the measuring device 20 may be large, resulting in a large error in the angle between the test plane 203 and the supporting plane 11. Therefore, the marking point 208 is the center point of the geometric figure formed by connecting the three first positioning points 207 in sequence, so that the marking point 208 is always located in the plane formed by the three first positioning points 207, the error of the test plane 203 obtained by the measuring device 20 is small, and the angle error between the test plane 203 and the supporting plane 11 is small, thereby improving the accuracy of the test result.

[0146] The marking block may be pasted first to determine the marking point 208, and then the first positioning point 207 may be set within a preset range with the marking point 208 as the center point. For example, the preset range may be 2 cm, 3 cm, 4 cm, 5 cm or 8 cm, and the preset range may be flexibly adjusted according to the size of the device to be tested 200. This allows the first positioning point 207 to be closer to the marking point 208 along the X-axis direction, further improving the accuracy of the test result.

[0147] Step S30 , driving the test swing arm 30 to rotate by the driving device 40 , so that the test swing arm 30 abuts against the test plane 203 .

[0148] After the test swing arm 30 contacts the test plane 203, the driving device 40 can continue to drive the test swing arm 30 to rotate, so that the test swing arm 30 applies thrust to the device to be tested 200, so that the test plane 203 rotates relative to the support plane 11, thereby testing the thrust resistance of the device to be tested 200. Figure 1 ) The scheme of applying thrust, in this scheme, the driving device 40 drives the test swing arm 30 to rotate, which can more accurately control the thrust and obtain more accurate test results. In addition, it can realize automated testing and improve test efficiency.

[0149] On this basis, when the distance between the second end 32 of the test swing arm 30 and the test plane 203 is less than or equal to the preset distance, the test swing arm 30 is parallel to the test plane 203 .

[0150] When the distance between the second end 32 of the test swing arm 30 and the test plane 203 is less than or equal to the preset distance, if the test swing arm 30 intersects the test plane 203, the thrust applied by the test swing arm 30 on the test plane 203 has a component force, and the force of the test swing arm 30 is not fully used to push the test plane 203. In this case, the test result of the anti-thrust value of the device to be tested 200 has a low accuracy.

[0151] When the test swing arm 30 or the device to be tested 200 is in the test position, the test swing arm 30 is parallel to the test plane 203, so that almost all the force of the test swing arm 30 can be used to push the test plane 203, reducing losses. The calculated thrust value of the test swing arm 30 can be closer to the anti-thrust value of the device to be tested 200, thereby improving the accuracy of the test results.

[0152] After step S30, the thrust resistance test method further includes:

[0153] Step S40, the driving device 40 drives the test swing arm 30 to continue to rotate, so that the test swing arm 30 pushes the device to be tested 200 to rotate;

[0154] Step S50, measuring a test angle between the support plane 11 and the test plane 203;

[0155] Please refer to Fig.11 , Fig.12 and Fig.13 , Fig.13 A vector diagram of a test plane 203 and a support plane 11 of a thrust resistance test device provided in an embodiment of the present application under test conditions. Fig.13 The straight lines with arrows in them represent vectors.

[0156] When the test swing arm 30 rotates to reach a preset torque, the driving device 40 stops driving the test swing arm 30 to rotate. The test angle between the support plane 11 and the test plane 203 can be measured by the measuring device 20. The test state may refer to a state in which the test swing arm 30 stops pushing the test plane 203. In the test state, the normal vector of the test plane 203 obtained according to the coordinates of at least three first positioning points 207 is m2, the normal vector of the support plane 11 obtained according to the coordinates of at least three second positioning points 111 is n2, and the test angle between the test plane 203 and the support plane 11 is γ2. According to the formula: cosγ2=<n2,m2>, γ2 can be calculated.

When γ3 is greater than the preset angle, the test is unqualified, that is, the device 200 under test cannot remain stable under the preset torque, has a large angle change, and has low hovering stability, and further improvement of the device 200 under test is required.

[0160] In some embodiments, see Fig.11 After step S30, the anti-thrust force test method further includes:

[0161] In step S70 , the driving device 40 drives the test swing arm 30 to continue rotating, so that the test swing arm 30 pushes the device to be tested 200 to rotate until the device to be tested 200 falls over.

[0162] The driving device 40 drives the test swing arm 30 to continue to rotate, so that the second end 32 of the test swing arm 30 applies a thrust to the test plane 203, and the second end 32 of the test swing arm 30 pushes the test plane 203 to rotate relative to the support plane 11 until the device to be tested 200 falls over, so that the test plane 203 is parallel to the support plane 11, and the maximum torque T of the second end 32 of the test swing arm 30 is recorded. max , according to T max Calculate the maximum thrust F max , the maximum thrust F max That is, the maximum thrust resistance of the device 200 to be tested.

[0163] Please refer to Fig.11 and Fig.14 , Fig.14A test logic diagram of an anti-thrust test method provided in an embodiment of the present application. In the anti-thrust test method, a linkage test is realized by cooperating with a measuring device 20 and a driving device 40. First, the test preparation is performed so that the device to be tested 200 is located within the depth of field of the measuring device 20, so that the measuring device 20 can obtain the test plane 203 of the device to be tested 200. In addition, the driving device 40 is turned on so that the driving device 40 can drive the test swing arm 30 to rotate. Then, the initial angle between the support plane 11 of the workbench 10 and the test plane 203 is measured by the measuring device 20; the measuring device 20 feeds back the initial angle to the driving device 40, and the driving device 40 drives the test swing arm 30 to rotate so that the test swing arm 30 is parallel to the test plane 203. Then, the driving device 40 drives the test swing arm 30 to continue to rotate, so that the test swing arm 30 pushes the test plane 203 to rotate, and at the same time, the measuring device 20 measures and records the angle between the test plane 203 and the support plane 11.

[0164] If it is necessary to test whether the thrust resistance of the device to be tested 200 is qualified, when the driving device 40 drives the test swing arm 30 to rotate to the preset torque, the driving device 40 stops driving after the test is finished, and controls the measuring device 20 to finish the test, and the measuring device 20 outputs the test result, which is the test angle between the support plane 11 and the test plane 203 measured by the measuring device 20. According to the angle difference between the test angle and the initial angle, the test conclusion is output, which is the test passing or the test failing.

[0165] If it is necessary to test the maximum thrust resistance of the device to be tested 200, the driving device 40 drives the test swing arm 30 to rotate until the measuring device 20 detects that the test swing arm 30 pushes the device to be tested 200 to fall over. The measuring device 20 ends the test and controls the driving device 40 to end the test. The driving device 40 outputs the test result, which is the maximum torque provided by the driving device 40 to the test swing arm 30. The maximum thrust resistance is calculated based on the maximum torque, and the test conclusion is output, which is the value of the maximum thrust resistance.
