Description

Technical Field

[0001] The present invention relates to the technical field of testing, and particularly to a protective case testing method and a testing device. Background Art

[0002] To improve the protection of electronic devices such as mobile phones and tablet computers, a protective case is often installed on the outside of the electronic device. Taking the protective case as an example, the protective case is classified by texture into leather, silicone, cloth, hard plastic, soft plastic, etc. Among them, for a protective case made of silicone or plastic, a key groove is generally set at the position of the electronic device key, and a key protrusion is formed on the outside of the key groove. The key groove is used to accommodate the electronic device key, so as to avoid opening a hole at the position of the electronic device key, thereby improving the protection ability of the key. When pressing the key protrusion, the protective case can be deformed to squeeze the internal electronic device key, so as to realize the triggering operation of the key.

[0003] However, when the depth of the key groove is greater than the distance that the electronic device key protrudes from the side wall of the mobile phone, the distance between the bottom of the key groove and the electronic device key is too large, resulting in a poor pressing feel after pressing a certain distance to contact the electronic device key; when the depth of the key groove is less than the distance that the electronic device key protrudes from the side wall of the mobile phone, the bottom of the key groove will squeeze the electronic device key, which may cause the problem of mis-triggering. In the prior art test, generally, the depth of the key groove is tested alone. However, when the protective case is installed on the mobile phone, deformation will occur, resulting in a change in the depth of the key groove, making the test result not match the actual situation, resulting in a problem that the protective case with a qualified test result has a large distance between the bottom of the key groove and the electronic device key after being put on the mobile phone, resulting in a poor feel, or squeezing the electronic device key to cause mis-touch.

[0004] Therefore, it is urgent to study a protective case testing method and a testing device to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a protective case testing method and a testing device to improve the use feel of the protective case and reduce the probability of mis-touch.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A protective case testing method includes the following steps:

[0008] Determine the alignment position where the pressing part of the internal pressing head replacing the electronic device key is flush with the side wall of the electronic device model;

[0009] Based on the size of the electronic device key protruding from the side wall of the mobile phone, determine the standard position of the internal pressing head relative to the electronic device model;

[0010] The inner pressure head retracts to the first zero point position inside the alignment position;

[0011] Put the protective cover on the electronic device model, with the key groove facing the inner pressure head;

[0012] Move the internal pressure head outward and measure the pressure on the internal pressure head in real time. When the pressure reaches the contact pressure value, record the distance the internal pressure head moves and the pressure it receives when it is in the aligned position. The contact pressure value range is 1gf-3gf.

[0013] Determine whether the internal pressure head reaches the standard position. If so, record the pressure applied to the internal pressure head when it reaches the standard position. Otherwise, the internal pressure head continues to move outward to the standard position and record the pressure applied to the internal pressure head.

[0014] As an optional technical solution for a protective cover testing method, when it is detected that the pressure exerted on the internal pressure head reaches the contact pressure value, the position of the internal pressure head is recorded as the contact position. Then, when the internal pressure head moves to the standard position, it is determined whether the moving distance of the internal pressure head from the contact position to the standard position is greater than the rigid distance. If so, the pressure exerted on the internal pressure head when it moves the rigid distance from the contact position is recorded as the rigid pressure; otherwise, the internal pressure head continues to move outward the rigid distance, and the rigid pressure exerted on the internal pressure head is recorded, where the range of the rigid distance is 0.1mm-0.3mm.

[0015] As an optional technical solution for testing a protective cover, when the internal pressure head moves outward a rigid distance, it is determined whether the rigid pressure applied to the internal pressure head is greater than a first internal pressure value. If so, the position of the internal pressure head at the first internal pressure value is recorded as a first internal position, and the position of the internal pressure head at the second internal pressure value is recorded as a second internal position. The second internal pressure value is less than the first internal pressure value and greater than the contact pressure value.

[0016] Otherwise, the internal pressure head continues to move outward to the first inner position and records the first internal pressure value and the second internal pressure value, where the second internal pressure value is smaller than the first internal pressure value and larger than the contact pressure value.

[0017] As an optional technical solution for the protective cover test method, determining the alignment position of the internal pressure head includes the following steps:

[0018] Installing the electronic device model on the base of the test device, installing the positioning member on the electronic device model, the electronic device model having a test channel, the positioning portion of the positioning member being located outside the electronic device model and blocking the test channel;

[0019] Move the inner ram outward to abut the detents and mark the aligned position.

[0020] As an alternative technical solution of a protective cover testing method, when the pressure received by the inner pressure head ranges from 3 gf to 6 gf during the process of the inner pressure head moving to abut against the positioning part, it is determined that the inner pressure head abuts against the positioning part; and / or,

[0021] During the process of the inner pressure head moving outward and abutting against the moving positioning part, the moving speed range of the inner pressure head is 3 mm / min - 10 mm / min.

[0022] As an alternative technical solution of a protective cover testing method, when the pressure received by the inner pressure head at the standard position is less than the contact pressure value, the outer pressure head arranged opposite to the inner pressure head moves inward and abuts against the protective cover. When the pressure received by the inner pressure head at the standard position is equal to the contact pressure value, the first pressing pressure applied by the outer pressure head is recorded.

[0023] As an alternative technical solution of a protective cover testing method, the inner pressure head is held at the standard position;

[0024] The outer pressure head continues to move inward. When the pressure received by the inner pressure head is the operating pressure, the second pressing pressure received by the outer pressure head is recorded, where the operating pressure is the pressure required when the key of the electronic device is pressed and triggered.

[0025] As an alternative technical solution of a protective cover testing method, the inner pressure head retracts to the first zero position inside the alignment position;

[0026] The outer pressure head moves towards the inner pressure head, and the pressure received by the outer pressure head is detected in real time. When the outer pressure head receives the first external pressure value, the first external position where the outer pressure head is located is recorded. When the outer pressure head receives the second external pressure, the second external position where the outer pressure head is located is recorded, where the difference range between the first external pressure value and the second external pressure value is 100 gf - 200 gf.

[0027] As an alternative technical solution of a protective cover testing method, along the length direction of the key, the outer pressure head moves an offset distance, then applies a third pressing pressure, and records the pressure received by the inner pressure head, where the third pressing pressure range is 1000 gf - 1100 gf, and the offset distance is determined according to the length of the key of the electronic device.

[0028] A protective cover testing device for implementing the protective cover testing method according to any one of the above technical solutions, comprising:

[0029] A base provided with an installation part;

[0030] A fixed electronic device model fixed to the installation part and having a key channel;

[0031] An inner pressure head movably arranged on the base along a first direction and passing through the key channel;

[0032] The first driving component is arranged on the base, and its output end is connected to the inner pressing head through a first pressure sensor.

[0033] The present invention has at least the following beneficial effects:

[0034] The present invention provides a protective cover testing method and testing equipment. The protective cover testing method includes the following steps: determining the alignment position where the pressing part of the inner pressing head replacing the electronic device key is flush with the side wall of the electronic device model; determining the standard position of the inner pressing head relative to the electronic device model based on the size of the electronic device key protruding from the side wall of the mobile phone; retracting the inner pressing head to the first zero position inside the alignment position, and the size between the inner pressing head at the first zero position and the side wall of the electronic device model is greater than the size of the electronic device key protruding from the side wall of the mobile phone; putting the protective cover on the electronic device model with the key groove facing the inner pressing head; moving the inner pressing head outwards and detecting the pressure received by the inner pressing head in real time. When the pressure reaches the contact pressure value, record the moving distance of the inner pressing head and record the pressure received by the inner pressing head when it is at the alignment position. Among them, the range of the contact pressure value is 1gf - 3gf; determining whether the inner pressing head reaches the standard position. If so, record the pressure received by the inner pressing head when it reaches the standard position. Otherwise, the inner pressing head continues to move outwards to the standard position and record the pressure received by the inner pressing head. With the above testing method, during the test, the protective cover is put on the electronic device model and detected under the simulated use state, thereby improving the authenticity of the detection and the reliability of the detection result. Among them, using the inner pressing head to simulate the electronic device key, when the pressure received by the inner pressing head reaches the contact pressure value, it means that the bottom of the key groove of the inner pressing head and the protective cover are in contact. At this time, record the distance of the inner pressing head, so as to determine the distance between the bottom of the protective cover and the side wall of the electronic device model when the protective cover is put on the electronic device model, and thus judge the relationship between the size of the electronic device key protruding from the side wall of the mobile phone and the depth of the key groove of the protective cover in the use state; thus, it can be judged whether the protective cover is qualified or how to make improvements according to this result. In addition, the method of first retracting the inner pressing head and then putting on the protective cover avoids jamming during the installation process, improves the efficiency of putting the protective cover on the electronic device model, and at the same time, avoids squeezing the inner pressing head during the installation process and also avoids deformation of the protective cover, thereby ensuring the reliability of the detection result. Finally, first making the inner pressing head contact the bottom of the key groove, then continuing to move outwards, and detecting the pressure received by the inner pressing head at the standard position avoids the influence on the protective cover when first testing the pressure received by the inner pressing head at the standard position, thereby affecting the detection accuracy of the depth of the key groove.

[0053] Before explaining any implementation manner of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0054] In the present application, the terms "comprising", "including", "having" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0055] In the present application, the term "and / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present application generally represents an "and / or" relationship between the front and rear associated objects.

[0056] In the present application, the terms "connect", "combine", "couple", "mount" may be direct connection, combination, coupling or mounting, or may be indirect connection, combination, coupling or mounting. Among them, by way of example, direct connection means that two parts or components are connected together without the need for an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling, and may include electrical connection or coupling.

[0057] In this application, those of ordinary skill in the art will understand that relative terms used in connection with quantities or conditions (e.g., "about", "approximately", "substantially", etc.) are intended to include the recited value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacture, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose ranges defined by the absolute values of two endpoints. The relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values without the use of relative terms should also be disclosed as specific values with tolerances. In addition, when expressing relative angular positional relationships (e.g., substantially parallel, substantially perpendicular), "substantially" may refer to plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0058] In this application, those of ordinary skill in the art will understand that the functions performed by a component may be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part may also be performed by one part, one component, or a combination of multiple parts.

[0059] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as limiting the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that the orientation terms such as the upper side, the lower side, the left side, the right side, the front side, the rear side, etc. not only represent the positive orientation, but can also be understood as the side orientation. For example, the lower side may include directly below, lower left, lower right, lower front, and lower rear, etc.

[0060] As Figures 1 to 8 shown, this embodiment provides a method for testing a protective case. The protective case is sleeved on electronic devices such as mobile phones and tablet computers. The protective case can be a mobile phone protective case 1000, a tablet computer protective case, or a protective case for other soft electronic devices. The electronic device model can be a mobile phone model 200, a tablet computer model, or other electronic device models. For ease of description, the following will be described by taking the process example of testing with the mobile phone protective case 1000 sleeved on the mobile phone model 200.

[0061] The method for testing the protective case includes the following steps:

[0062] Determine the alignment position where the pressing portion of the inner indenter 300 replacing the mobile phone key is flush with the side wall of the mobile phone model 200 replacing the mobile phone.

[0063] Based on the above alignment position and the size of the mobile phone keys protruding from the side wall of the mobile phone, determine the standard position of the inner indenter 300 relative to the mobile phone model 200. For example, when not pressed, when the size of the mobile phone keys protruding from the side wall of the mobile phone is 1 mm, the distance between the inner indenter 300 at the standard position and the side wall of the mobile phone model 200 is 1 mm.

[0064] The inner indenter 300 retracts to the first zero position inside the alignment position, and the size between the inner indenter 300 at the first zero position and the side wall of the mobile phone model 200 is greater than the size of the mobile phone keys protruding from the side wall of the mobile phone.

[0065] Put the mobile phone case 1000 on the mobile phone model 200, and the key groove 1100 faces the inner indenter 300.

[0066] Move the inner indenter 300 outwards and detect the pressure on the inner indenter 300 in real time. When the pressure reaches the contact pressure value, record the moving distance of the inner indenter 300, and record the pressure on the inner indenter 300 when it is at the alignment position. Among them, the range of the contact pressure value is 1 gf - 3 gf. This moving distance is the distance from the bottom of the key groove 1100 to the first zero position in the use state, and it can be calculated the distance between the side wall of the mobile phone model 200 and the bottom of the key groove 1100.

[0067] Judge whether the inner indenter 300 reaches the standard position. If so, record the pressure on the inner indenter 300 when it reaches the standard position. Otherwise, the inner indenter 300 continues to move outwards to the standard position and record the pressure on the inner indenter 300.

[0068] Along the width direction of the mobile phone model 200, from the center position to the side position of the mobile phone model 200, the inner indenter 300 sequentially passes through the alignment position and the standard position from the first zero position. In some embodiments, the first zero position is 1 mm or 0.5 mm inside the alignment position.

[0069] With the above-mentioned test method, during the test, the mobile phone case 1000 is put on the mobile phone model 200, and the mobile phone case 1000 is detected under the simulated usage state, thereby improving the authenticity of the detection and the reliability of the detection result. Among them, the inner indenter 300 is used to simulate the mobile phone key. When the pressure received by the inner indenter 300 reaches the contact pressure value, it means that the bottom of the inner indenter 300 abuts against the bottom of the key groove 1100 of the mobile phone case 1000. At this time, the distance of the inner indenter 300 is recorded, so that the distance between the bottom of the mobile phone case 1000 and the side wall of the mobile phone model 200 can be determined when the mobile phone case 1000 is put on the mobile phone model 200, and thus the relationship between the size of the mobile phone key protruding from the side wall of the mobile phone and the depth of the key groove 1100 of the mobile phone case 1000 in the usage state can be judged; thus, it can be judged whether the mobile phone case 1000 is qualified or how to make improvements according to this result; recording the pressure received by the inner indenter 300 when it is in the aligned position can judge whether the mobile phone case 1000 is deformed and affects the normal protrusion of the mobile phone key; in addition, the method of first retracting the inner indenter 300 and then putting on the mobile phone case 1000 avoids jamming during the installation process, improves the efficiency of putting the mobile phone case 1000 on the mobile phone model 200, and at the same time, avoids squeezing the inner indenter 300 during the installation process and also avoids deformation of the mobile phone case 1000, thereby ensuring the reliability of the detection result. Finally, first making the inner indenter 300 abut against the bottom of the key groove 1100, then continuing to move outwards, and detecting the pressure received by the inner indenter 300 at the standard position avoids the influence on the mobile phone case 1000 when first testing the pressure received by the inner indenter 300 at the standard position, thereby affecting the detection accuracy of the depth of the key groove 1100.

[0070] In other words, in order to improve the use feel, generally, the bottom of the key groove 1100 of the mobile phone case 1000 contacts the mobile phone key, and the extrusion force between the two is between 1 gf and 5 gf. During the detection, if the pressure between the inner indenter 300 at the standard position and the bottom of the key groove 1100 of the mobile phone case 1000 is detected first, it will cause the mobile phone case 1000 to deform. On this basis, when detecting the distance between the bottom of the key groove 1100 of the mobile phone case 1000 and the side wall of the mobile phone model 200, an error will occur.

[0071] It should be noted that when the distance that the inner indenter 300 at the standard position extends out of the side wall of the mobile phone model 200 is greater than the depth of the key groove 1100, the mobile phone case 1000 will have elastic deformation, and an error will occur when measuring the depth of the key groove 1100 again.

[0072] The test of the mobile phone case 1000 also has other items. Exemplarily, when it is detected that the pressure received by the inner indenter 300 reaches the contact pressure value, the position of the inner indenter 300 is recorded as the contact position. Then, when the inner indenter 300 moves to the standard position, it is judged whether the moving distance of the inner indenter 300 from the contact position to the standard position is greater than the rigid distance. If so, the pressure received by the inner indenter 300 when moving the rigid distance from the contact position is recorded as the rigid pressure; otherwise, the inner indenter 300 continues to move outward by the rigid distance, and the rigid pressure received by the inner indenter 300 is recorded. Among them, the range of the rigid distance is 0.1mm - 0.3mm. Among them, the rigidity of the mobile phone case 1000 at the button groove 1100 is calculated according to the rigid pressure, the contact pressure and the rigid distance. Specifically, the pressure difference is calculated according to the rigid pressure and the contact pressure, and the rigidity of the mobile phone case 1000 at the button groove 1100 is calculated in combination with the rigid distance. Among them, the range of the rigid distance is 0.1mm - 0.3mm. Specifically, the rigid distance is 0.2mm.

[0073] When the inner indenter 300 moves outward by the rigid distance, it is judged whether the rigid pressure received by the inner indenter 300 is greater than the first internal pressure value. If so, the position of the inner indenter 300 when at the first internal pressure value is recorded as the first internal position, and the position of the inner indenter 300 when at the second internal pressure value is recorded as the second internal position. The second internal pressure value is less than the first internal pressure value and greater than the contact pressure value; otherwise, the inner indenter 300 continues to move outward to the first internal position, and the first internal pressure value and the second internal pressure value are recorded. The second internal pressure value is less than the first internal pressure value and greater than the contact pressure value; and the difference between the first internal position and the second internal position is calculated to obtain the displacement difference of the inner indenter 300. Exemplarily, the first internal pressure value is 30gf. The second internal pressure value is 3gf. The measurement of the above method can determine the displacement amount generated when the inner indenter 300 receives different pressures, so as to be used to judge the deformation situation generated by applying different forces when the mobile phone case 1000 is in use. In other embodiments, the first internal pressure value is 35gf or 40gf.

[0074] Determining the alignment position of the inner indenter 300 includes the following steps: Install the mobile phone model 200 on the base 100 of the test device, install the positioning member 700 on the mobile phone model 200. The mobile phone model 200 has a test channel 220. The positioning portion 721 of the positioning member 700 is located outside the mobile phone model 200 and blocks the test channel 220; Move the inner indenter 300 outward to abut against the positioning portion 721 and mark it as the alignment position. This method enables the inner indenter 300 to be mechanically positioned through the positioning member 700, thus ensuring the positioning accuracy.

[0075] To improve the degree of automation of positioning, in some embodiments, when the pressure range received by the inner pressure head 300 is 3 gf - 6 gf during the process of the mobile inner pressure head 300 abutting against the positioning portion 721, it is determined that the inner pressure head 300 and the positioning portion 721 are in abutment. Specifically, when the pressure received by the inner pressure head 300 reaches 2.5 gf, it is determined that the inner pressure head 300 and the positioning portion 721 are in abutment. With this method, the pressure detected by the sensor connected to the inner pressure head 300 is 2.5 gf, and a signal can be sent to the controller, so that the inner pressure head 300 can stop moving further and mark the current position as the alignment position. On this basis, based on the alignment position and the size of the mobile phone button protruding from the side wall of the mobile phone, the standard position of the inner pressure head 300 replacing the mobile phone button relative to the mobile phone model 200 can be determined. That is, assuming that in a certain model of mobile phone, the size of the mobile phone button protruding from the side wall of the mobile phone is 1 mm, the inner pressure head 300 can reach the standard position by protruding 1 mm outward from the alignment position to simulate the mobile phone button.

[0076] Among them, during the process of the inner pressure head 300 moving outward and abutting against the positioning portion 721, the moving speed range of the inner pressure head 300 is 3 mm / min - 10 mm / min. Specifically, during the process of moving the inner pressure head 300 to abut against the positioning portion 721, the moving speed of the inner pressure head 300 is 5 mm / min.

[0077] When the depth of the button groove 1100 is greater than the distance of the mobile phone button protruding from the side wall of the mobile phone, when pressing the button, a certain force needs to be applied to make the bottom of the button groove 1100 of the mobile phone case 1000 abut against the mobile phone button. To obtain the magnitude of this force. After the above test is completed, the inner pressure head 300 is kept at the standard position and the following test is carried out. The outer pressure head 500 arranged opposite to the inner pressure head 300 moves inward and abuts against the mobile phone case 1000. When the pressure received by the inner pressure head 300 at the standard position is equal to the contact pressure value, the first pressing pressure applied by the outer pressure head 500 is recorded. Among them, the contact pressure value is 2.5 gf. At this time, the side wall of the mobile phone case 1000 is clamped between the inner pressure head 300 and the outer pressure head 500.

[0078] When pressing the phone buttons with the phone equipped with the phone case 1000, it is necessary to press the phone case 1000 together. Since the pressing force of the phone buttons has a fixed value, in order to consider the user experience, it is necessary to clearly know the force required to press the phone buttons when the phone case 1000 is on. Different shapes of the button grooves 1100 of the phone case 1000, as well as different chamfers, structures and materials, will all affect the force when pressing the phone buttons. To accurately know the pressing force, it can also be obtained through the following test methods. Specifically, keep the inner pressing head 300 in the standard position; the outer pressing head 500 continues to move inward. When the pressure received by the inner pressing head 300 is the operating pressure, record the second pressing pressure received by the outer pressing head 500. Among them, the operating pressure is the pressure required when the phone buttons are pressed and triggered. The second pressing pressure is greater than the operating pressure. Specifically, the operating pressure is the force required to press and trigger the phone buttons in the state without using the phone case 1000. Among them, the operating pressure can be 330 gf.

[0079] The producer can judge whether the use of the phone case 1000 meets the user's needs and whether it helps to ensure customer satisfaction according to the test results. If it is detected that the second pressing pressure is too large, it is necessary to adjust the material and structure of the phone case 1000.

[0080] In some embodiments, it is also necessary to test the position difference of the outer pressing head 500 when it receives two different pressures. Specifically, the inner pressing head 300 retracts to the first zero position inside the alignment position; the outer pressing head 500 moves towards the inner pressing head 300, and the pressure received by the outer pressing head 500 is detected in real time. When the outer pressing head 500 receives the first external pressure value, record the first external position where the outer pressing head 500 is located. When the outer pressing head 500 receives the second external pressure, record the second external position where the outer pressing head 500 is located. Among them, the difference range between the first external pressure value and the second external pressure value is 100 gf - 200 gf. Specifically, the first external pressure is 5 gf, and the second external pressure is 200 gf. In this embodiment, the outer pressing head 500 moves inward from the second zero position. The second zero position can be 6.5 mm away from the outermost side of the phone case 1000. The moving speed of the outer pressing head 500 is 5 mm / min.

[0081] In order to test the force required for the mobile phone keys to be pressed due to accidental touch, in some embodiments, when the inner pressing head 300 is in the standard position, along the length direction of the key, the outer pressing head 500 moves an offset distance, then applies a third pressing pressure, and records the pressure received by the inner pressing head 300, where the third pressing pressure ranges from 1000 gf to 1100 gf, and the offset distance is determined according to the length of the mobile phone key. Specifically, the third pressing pressure is 1050 gf. This method can determine whether it will be accidentally pressed under the third pressing pressure according to the force received by the inner pressing head 300. Of course, it is also possible to obtain how much force is specifically required to trigger the mobile phone key when pressing one end of the mobile phone key according to the above method. The offset distance is 5 mm.

[0082] In addition, when the mobile phone key is the volume key, it is necessary to press the upper end or the lower end to increase or decrease the volume. In order to measure whether pressing the upper end of the volume key with a force of 1050 gf can complete the trigger of volume increase in the state with the mobile phone case 1000, the above method can also be used to complete the test.

[0083] After the above test is completed, the following test can also be carried out. Along the length direction of the key, the outer pressing head 500 moves an offset distance, then applies a third pressing pressure of 1050 gf, and then the inner pressing head 300 starts from the first zero position and moves outward at a speed of 5 mm / min, and records the displacement when the inner pressing head 300 detects 2.5 gf.

[0084] After the above test is completed, the following test can also be carried out. The outer pressing head 500 contacts the outer side wall of the mobile phone case 1000, and the distance required for the inner pressing head 300 to move from the alignment position to contact the bottom of the key groove 1100. When the outer pressing head 500 starts from the second zero position and detects that the pressure is 2.5 gf, it stops, and then the inner pressing head 300 starts from the first zero position and stops moving when the pressure received by the inner pressing head 300 is 2.5 gf, and calculates the distance between the inner pressing head 300 at this position and the alignment position.

[0085] After the above test is completed, the following test can also be carried out. The outer pressing head 500 starts from the second zero position and moves inward at a speed of 5 mm / min. When the force received by the outer pressing head 500 is 2.5 gf, it is recorded as the first outer position, and then it continues to move 0.2 mm and is recorded as the second outer position, and records the force of the outer pressing head 500 at the second outer position. According to the difference between the two forces and the two positions, the stiffness of the outer side of the mobile phone case 1000 is calculated.

[0086] After the above tests are completed, the following tests can also be carried out. Calculate the position difference between the position of the inner indenter 300 when it is subjected to 2.5 gf and the position of the inner indenter 300 when it is subjected to 100 gf. Specifically, the outer indenter 500 is located at the second zero position or abuts against the mobile phone case 1000 and the pressure is 2.5 gf. The inner indenter 300 starts from the first zero position until the pressure it receives reaches 2.5 gf, which is recorded as the third inner position. The inner indenter 300 continues to move, and when the pressure it receives reaches 100 gf, it is recorded as the fourth inner position, and calculate the position difference between the fourth inner position and the third inner position.

[0087] After the above tests are completed, the following tests can also be carried out. Calculate the position difference between the position of the outer indenter 500 when it is subjected to 2.5 gf and the position of the outer indenter 500 when it is subjected to 100 gf. Specifically, the inner indenter 300 is located at the standard position or the first zero position. The outer indenter 500 starts from the second zero position until the pressure it receives reaches 2.5 gf, which is recorded as the third outer position. The outer indenter 500 continues to move, and when the pressure it receives reaches 100 gf, it is recorded as the fourth outer position, and calculate the position difference between the fourth outer position and the third outer position.
