Description

Technical Field

[0001] This invention relates to the field of testing technology, and in particular to a method and equipment for testing protective cases. Background Technology

[0002] To enhance the protection of electronic devices such as mobile phones and tablets, protective cases are often added to the outside of these devices. Taking protective cases as an example, they are categorized by material, including leather, silicone, fabric, hard plastic, and soft plastic. Silicone or plastic protective cases typically have recessed grooves for the electronic device's buttons, with raised buttons on the outside of these grooves. The recesses accommodate the buttons, avoiding the need for openings at the buttons and thus improving their protection. Pressing the raised buttons deforms the protective case, squeezing the buttons inside to activate them.

[0003] However, when the depth of the button recess is greater than the distance the electronic device button protrudes from the side wall of the phone, the distance between the bottom of the recess and the button is too large, causing a considerable distance to be pressed before contact with the button, resulting in a poor tactile feel. Conversely, when the depth of the recess is less than the distance the button protrudes from the side wall, the bottom of the recess may press against the button, potentially leading to accidental activation. Current testing typically tests the depth of the button recess alone. However, when a protective case is installed on the phone, deformation occurs, altering the recess depth and causing the test results to deviate from reality. This results in a situation where a tested protective case, when applied to the phone, may cause an excessive distance between the recess and the button, leading to a poor tactile feel, or it may press against the button, causing accidental activation.

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

[0005] The purpose of this invention is to provide a protective case testing method and testing equipment to improve the feel of the protective case and reduce the probability of accidental touches.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

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

[0008] The alignment position is determined by placing the pressing part of the inner pressure head, which replaces the button of the electronic device, flush with the side wall of the electronic device model.

[0009] Based on the dimensions of the electronic device buttons protruding from the side wall of the phone, determine the standard position of the internal pressure head relative to the electronic device model;

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

[0011] Place the protective cover over the electronic device model, ensuring the button recesses are aligned with the inner pressure head;

[0012] The internal pressure head is moved outward and the pressure on the internal pressure head is monitored in real time. When the pressure reaches the contact pressure value, the moving distance of the internal pressure head is recorded, as well as the pressure on the internal pressure head when it is in the alignment position. The range of the contact pressure value is 1gf-3gf.

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

[0014] As an optional technical solution for testing protective covers, when the pressure on the inner pressure head reaches the contact pressure value, the position of the inner pressure head is recorded as the contact position. Then, when the inner pressure head moves to the standard position, it is determined whether the distance the inner pressure head moves from the contact position to the standard position is greater than the rigid distance. If so, the pressure experienced by the inner pressure head when it moves the rigid distance from the contact position is recorded as the rigid pressure. Otherwise, the inner pressure head continues to move outward the rigid distance, and the rigid pressure experienced by the inner pressure head is recorded. The range of the rigid distance is 0.1mm-0.3mm.

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

[0016] Otherwise, the internal pressure head continues to move outward to the first internal position and records the first internal pressure value and the second internal pressure value. The second internal pressure value is less than the first internal pressure value and greater than the contact pressure value. The difference between the first internal position and the second internal position is calculated to obtain the displacement difference of the internal pressure head, which is used to determine the deformation caused by applying different forces when using a mobile phone case.

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

[0018] The electronic device model is mounted on the base of the test equipment, and the positioning component is mounted on the electronic device model. The electronic device model has a test channel, and the positioning part of the positioning component is located on the outside of the electronic device model and blocks the test channel.

[0019] Move the inner pressure head outward to abut the positioning part and mark the alignment position.

[0020] As an optional technical solution for testing protective sleeves, during the process of moving the inner pressure head to abut against the positioning part, when the pressure range of the inner pressure head is 3gf-6gf, it is determined that the inner pressure head and the positioning part are in contact; and / or,

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

[0022] As an optional technical solution for testing protective covers, when the pressure on the inner pressure head in the standard position is less than the contact pressure value, the outer pressure head, which is arranged opposite to the inner pressure head, moves inward and abuts against the protective cover. When the pressure on the inner pressure head in 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 optional technical solution for testing protective sleeves, the internal pressure head is kept in a standard position;

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

[0025] As an optional technical solution for testing protective sleeves, the inner pressure head retracts to the first zero-point position inside the alignment position;

[0026] The external pressure head moves towards the internal pressure head, and the pressure on the external pressure head is detected in real time. When the external pressure head receives the first external pressure value, the first external position of the external pressure head is recorded. When the external pressure head receives the second external pressure, the second external position of the external pressure head is recorded. The difference between the first external pressure value and the second external pressure value is in the range of 100gf-200gf.

[0027] As an optional technical solution for testing protective covers, the outer pressure head moves an offset distance along the length of the button, then a third pressing pressure is applied, and the pressure received by the inner pressure head is recorded. The third pressing pressure ranges from 1000gf to 1100gf, and the offset distance is determined according to the length of the electronic device button.

[0028] A protective case testing device, used to implement the protective case testing method according to any of the above technical solutions, comprising:

[0029] The base is equipped with a mounting section;

[0030] An electronic device model is fixed to the mounting part and has a button channel;

[0031] An internal pressure head is movably disposed on the base along a first direction and passes through the key channel;

[0032] The first drive component is located on the base, and its output end is connected to the internal pressure head through the first pressure sensor.

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

[0034] This invention provides a protective case testing method and testing equipment. The protective case testing method includes the following steps: determining the alignment position as the flush position between the pressing part of the inner pressure head (replacing the button of an electronic device) and the side wall of the electronic device model; determining the standard position of the inner pressure head relative to the electronic device model based on the size of the electronic device button extending out of the side wall of the phone; retracting the inner pressure head to a first zero point position inside the alignment position, wherein the size between the inner pressure head at the first zero point position and the side wall of the electronic device model is greater than the size of the electronic device button extending out of the side wall of the phone; placing the protective case on the electronic device model, with the button groove facing the inner pressure head; moving the inner pressure head outward and detecting the pressure on the inner pressure head in real time; when the pressure reaches the contact pressure value, recording the moving distance of the inner pressure head and recording the pressure on the inner pressure head when it is in the alignment position; wherein the contact pressure value ranges from 1gf to 3gf; determining whether the inner pressure head has reached the standard position; if so, recording the pressure on the inner pressure head when it reaches the standard position; otherwise, continuing to move the inner pressure head outward to the standard position and recording the pressure on the inner pressure head. Using the aforementioned testing method, the protective case is placed on an electronic device model during testing, and the case is tested under simulated usage conditions, thereby improving the realism of the test and the reliability of the results. Specifically, an internal pressure head is used to simulate an electronic device button. When the pressure on the internal pressure head reaches the contact pressure value, it indicates that the internal pressure head and the bottom of the button groove on the protective case are in contact. The distance of the internal pressure head at this point is recorded, thus determining the distance between the bottom of the groove on the protective case and the side wall of the electronic device model when the case is placed on it. This allows for the determination of the relationship between the size of the electronic device button protruding from the side wall and the depth of the button groove on the protective case under usage conditions. Based on this result, it is possible to determine whether the protective case is qualified or how to improve it. Furthermore, retracting the internal pressure head before placing the protective case avoids installation jamming, improving the efficiency of placing the protective case on the electronic device model. It also avoids squeezing the internal pressure head and deforming the protective case during installation, thus ensuring the reliability of the test results. Finally, the inner pressure head first comes into contact with the bottom of the key groove, and then continues to move outward, while the pressure on the inner pressure head in the standard position is detected. This avoids the influence of the pressure on the protective sleeve when testing the pressure on the inner pressure head in the standard position first, which would affect the accuracy of the depth detection of the key groove.

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

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

[0055] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0056] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0057] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​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 associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

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

[0059] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0060] like Figures 1 to 8 As shown, this embodiment provides a method for testing protective cases, which are applied to electronic devices such as mobile phones and tablets. The protective case can be a mobile phone protective case 1000, a tablet protective case, or other flexible electronic device protective cases. The electronic device model can be a mobile phone model 200, a tablet model, or other electronic device models. For ease of description, the following explanation will use the process of testing a mobile phone protective case 1000 applied to a mobile phone model 200 as an example.

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

[0062] The alignment position is determined by placing the pressing part of the inner pressure head 300, which replaces the mobile phone buttons, flush with the side wall of the mobile phone model 200, which replaces the mobile phone.

[0063] Based on the alignment position and the size of the phone button protruding from the side wall of the phone, the standard position of the inner pressure head 300 relative to the phone model 200 is determined. For example, when the phone button is not pressed and the size of the protrusion from the side wall of the phone is 1mm, the distance between the inner pressure head 300 in the standard position and the side wall of the phone model 200 is 1mm.

[0064] The inner pressure head 300 retracts to the first zero point position inside the alignment position. The dimension between the inner pressure head 300 at the first zero point position and the side wall of the mobile phone model 200 is greater than the dimension of the mobile phone button extending out of the side wall of the mobile phone.

[0065] Place the phone case 1000 onto the phone model 200, with the button recess 1100 aligned with the inner pressure head 300.

[0066] The inner pressure head 300 is moved outward, and the pressure on the inner pressure head 300 is monitored in real time. When the pressure reaches the contact pressure value, the moving distance of the inner pressure head 300 is recorded, as well as the pressure on the inner pressure head 300 when it is in the aligned position. The contact pressure value ranges from 1gf to 3gf. This moving distance is the distance from the bottom of the button groove 1100 to the first zero point position in the use state. The distance between the side wall of the mobile phone model 200 and the bottom of the button groove 1100 can be calculated.

[0067] Determine whether the internal pressure head 300 has reached the standard position. If so, record the pressure received by the internal pressure head 300 when it reaches the standard position. Otherwise, the internal pressure head 300 continues to move outward to the standard position and the pressure received by the internal pressure head 300 is recorded.

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

[0069] Using the above testing method, during testing, the phone case 1000 is placed on the phone model 200, and the phone case 1000 is tested under simulated usage conditions, thereby improving the realism of the test and the reliability of the test results. Specifically, an internal pressure head 300 is used to simulate a phone button. When the pressure on the internal pressure head 300 reaches the contact pressure value, it indicates that the internal pressure head 300 and the bottom of the button groove 1100 of the phone case 1000 are in contact. The distance of the internal pressure head 300 at this point is recorded, thus determining the distance between the bottom of the groove of the phone case 1000 and the side wall of the phone model 200 when the phone case 1000 is placed on the phone model 200. This allows for the determination of the relationship between the size of the phone button protruding from the side wall of the phone and the depth of the button groove 1100 of the phone case 1000 under usage conditions; thus... The results can be used to determine whether the phone case 1000 is qualified or how to improve it. Recording the pressure on the inner pressure head 300 when it is in the aligned position can determine whether the phone case 1000 is deformed and affects the normal extension of the phone buttons. In addition, the method of retracting the inner pressure head 300 before putting on the phone case 1000 avoids jamming during the installation process, improves the efficiency of putting the phone case 1000 on the phone model 200, and avoids squeezing the inner pressure head 300 during the installation process, as well as avoiding deformation of the phone case 1000, thus ensuring the reliability of the test results. Finally, the inner pressure head 300 is first tested by contacting the bottom of the button groove 1100, and then it is moved outward. The pressure on the inner pressure head 300 in the standard position is tested. This avoids the influence of testing the pressure on the inner pressure head 300 in the standard position on the phone case 1000, which would affect the depth detection accuracy of the button groove 1100.

[0070] In other words, to improve the user experience, the bottom of the button recess 1100 of the phone case 1000 generally contacts the phone button, and the pressure between them is between 1gf and 5gf. During testing, if the pressure between the inner pressure head 300 in its standard position and the bottom of the button recess 1100 of the phone case 1000 is first measured, it will cause deformation of the phone case 1000. Based on this deformation, measuring the distance between the bottom of the button recess 1100 of the phone case 1000 and the side wall of the phone model 200 will result in errors.

[0071] It should be noted that when the distance by which the inner pressure head 300 protrudes from the side wall of the phone model 200 in the standard position is greater than the depth of the button groove 1100, the phone case 1000 will undergo elastic deformation, resulting in an error when measuring the depth of the button groove 1100 again.

[0072] The testing of the mobile phone case 1000 also includes other items. For example, when the pressure on the inner pressure head 300 reaches the contact pressure value, the position of the inner pressure head 300 is recorded as the contact position. Then, when the inner pressure head 300 moves to the standard position, it is determined whether the distance the inner pressure head 300 moves from the contact position to the standard position is greater than the rigid distance. If so, the pressure experienced by the inner pressure head 300 when moving the rigid distance from the contact position is recorded as the rigid pressure. Otherwise, the inner pressure head 300 continues to move outward a rigid distance, and the rigid pressure experienced by the inner pressure head 300 is recorded. The rigid distance ranges from 0.1mm to 0.3mm. The rigidity of the mobile phone case 1000 at the button recess 1100 is calculated based on the rigid pressure, contact pressure, and rigid distance. Specifically, the pressure difference is calculated based on the rigid pressure and contact pressure, and the rigidity of the mobile phone case 1000 at the button recess 1100 is calculated in conjunction with the rigid distance. The rigid distance ranges from 0.1mm to 0.3mm. Specifically, the rigid distance is 0.2mm.

[0073] When the inner pressure head 300 moves outward a rigid distance, it is determined whether the rigid pressure on the inner pressure head 300 is greater than the first inner pressure value. If so, the position of the inner pressure head 300 at the first inner pressure value is recorded as the first inner position, and the position of the inner pressure head 300 at the second inner pressure value is recorded as the second inner position. The second inner pressure value is less than the first inner pressure value and greater than the contact pressure value. Otherwise, the inner pressure head 300 continues to move outward to the first inner position, and the first inner pressure value and the second inner pressure value are recorded. The second inner pressure value is less than the first inner pressure value and greater than the contact pressure value. The difference between the first inner position and the second inner position is calculated to obtain the displacement difference of the inner pressure head 300. For example, the first inner pressure value is 30 gf. The second inner pressure value is 3 gf. The measurement of the above method can determine the displacement generated when the inner pressure head 300 is subjected to different pressures, which can be used to determine the deformation caused by applying different forces when the mobile phone protective case 1000 is used. In other embodiments, the first inner pressure value is 35 gf or 40 gf.

[0074] Determining the alignment position of the inner pressure head 300 includes the following steps: Mounting the mobile phone model 200 onto the base 100 of the testing equipment; mounting the positioning member 700 onto the mobile phone model 200; the mobile phone model 200 having a test channel 220; the positioning part 721 of the positioning member 700 located on the outside of the mobile phone model 200 and blocking the test channel 220; moving the inner pressure head 300 outward to abut against the positioning part 721, and marking this as the alignment position. This method allows the inner pressure head 300 to be mechanically positioned by the positioning member 700, thereby ensuring positioning accuracy.

[0075] To improve the automation of positioning, in some embodiments, during the process of moving the inner pressure head 300 to abut against the positioning part 721, the inner pressure head 300 and the positioning part 721 are determined to abut when the pressure on the inner pressure head 300 is in the range of 3gf-6gf. Specifically, the inner pressure head 300 and the positioning part 721 are determined to abut when the pressure on the inner pressure head 300 reaches 2.5gf. This method allows the sensor connected to the inner pressure head 300 to detect a pressure of 2.5gf, which sends a signal to the controller, allowing the inner pressure head 300 to stop moving and mark the current position as the alignment position. Based on this, and based on the alignment position and the size of the phone button extending out of the side wall of the phone, the standard position of the inner pressure head 300, which replaces the phone button, relative to the phone model 200 can be determined. That is, assuming that in a certain model of phone, the size of the phone button extending out of the side wall of the phone is 1mm, the inner pressure head 300 can reach the standard position by extending 1mm outward from the alignment position to simulate the phone button.

[0076] During the process of the inner pressure head 300 moving outward and abutting the positioning part 721, the moving speed of the inner pressure head 300 ranges from 3 mm / min to 10 mm / min. Specifically, during the process of moving the inner pressure head 300 to abut the positioning part 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 the phone button extends out of the side wall of the phone, a certain force needs to be applied when pressing the button so that the bottom of the button groove 1100 of the phone case 1000 abuts against the phone button. To obtain the magnitude of this force, after the above test is completed, the inner pressure head 300 is held in the standard position, and the following test is performed: the outer pressure head 500, which is arranged opposite to the inner pressure head 300, moves inward and abuts against the phone case 1000. When the pressure on the inner pressure head 300 in the standard position is equal to the contact pressure value, the first pressing pressure applied by the outer pressure head 500 is recorded. The contact pressure value is 2.5gf. At this time, the side wall of the phone case 1000 is sandwiched between the inner pressure head 300 and the outer pressure head 500.

[0078] When pressing the buttons on a phone with a phone case 1000 on, the phone case 1000 must be pressed simultaneously. Since the button pressing force has a fixed value, to ensure a good user experience, it's necessary to know the required force when pressing the buttons with the phone case 1000 on. Differences in the shape, chamfering, and material of the button recess 1100 on the phone case 1000 will affect the pressing force. To accurately determine the pressing force, the following testing method can be used: Specifically, keep the inner pressure head 300 in the standard position; continue moving the outer pressure head 500 inwards. When the pressure on the inner pressure head 300 reaches the operating pressure, record the second pressing pressure on the outer pressure head 500. The operating pressure is the pressure required to press and trigger the phone button, and the second pressing pressure is greater than the operating pressure. Specifically, the operating pressure is the force required to press and trigger the phone button without the phone case 1000 on. The operating pressure can be 330gf.

[0079] Manufacturers can use the test results to determine whether the phone case 1000 meets user needs and contributes to customer satisfaction. If the second press pressure is found to be too high, the material and structure of the phone case 1000 need to be adjusted.

[0080] In some embodiments, it is also necessary to test the positional difference when the external pressure head 500 is subjected to two different pressures. Specifically, the inner pressure head 300 retracts to a first zero-point position inside the aligned position; the outer pressure head 500 moves towards the inner pressure head 300, and the pressure on the outer pressure head 500 is detected in real time. When the outer pressure head 500 is subjected to a first external pressure value, the first external position of the outer pressure head 500 is recorded; when the outer pressure head 500 is subjected to a second external pressure, the second external position of the outer pressure head 500 is recorded. The difference between the first and second external pressure values ​​ranges from 100gf to 200gf. Specifically, the first external pressure is 5gf, and the second external pressure is 200gf. In this embodiment, the outer pressure head 500 moves inward from the second zero-point position. The second zero-point position can be 6.5mm from the outermost edge of the phone case 1000. The moving speed of the outer pressure head 500 is 5mm / min.

[0081] To test the force required to trigger a button press due to accidental touch, in some embodiments, with the inner pressure head 300 in its standard position, the outer pressure head 500 is moved an offset distance along the length of the button, and a third pressing pressure is applied. The pressure on the inner pressure head 300 is recorded, where the third pressing pressure ranges from 1000gf to 1100gf, and the offset distance is determined based on the length of the button. Specifically, the third pressing pressure is 1050gf. This method can determine whether an accidental press will occur under the third pressing pressure based on the force applied to the inner pressure head 300. Alternatively, the above method can be used to determine the specific force required to trigger the button when pressing one end. The offset distance is 5mm.

[0082] Additionally, when the phone's buttons are volume buttons, you need to press the top or bottom to increase or decrease the volume. To test whether pressing the top of the volume button and applying a force of 1050gf can trigger the volume increase when the phone is covered by a protective case 1000, you can also use the above method to perform the test.

[0083] After the above tests are completed, the following tests can be performed: along the length of the button, the outer pressure head 500 moves an offset distance, and then a third pressing pressure of 1050gf is applied. Then the inner pressure head 300 is triggered from the first zero point position and moves outward at a speed of 5mm / min. The displacement of the inner pressure head 300 when it detects 2.5gf is recorded.

[0084] After the above tests are completed, the following tests can be performed: the outer pressure head 500 contacts the outer wall of the phone case 1000, and the inner pressure head 300 moves from the alignment position to the bottom of the button recess 1100. The outer pressure head 500 starts from the second zero point position and stops when it detects a pressure of 2.5gf. Then, the inner pressure head 300 starts from the first zero point position and stops moving when the pressure it receives is 2.5gf. The distance between the inner pressure head 300 and the alignment position at that position is calculated.

[0085] After the above tests are completed, the following tests can be performed: the external pressure head 500 starts from the second zero point position and moves inward at a speed of 5 mm / min. When the force on the external pressure head 500 is 2.5 gf, it is recorded as the first external position. Then it continues to move 0.2 mm and is recorded as the second external position. The force on the external pressure head 500 at the second external position is recorded. Based on the difference between the two forces and the two positions, the stiffness of the outer side of the mobile phone protective case 1000 is calculated.

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

[0087] After the above tests are completed, the following test can be performed to calculate the position difference between the position of the external pressure head 500 when it is subjected to 2.5gf and the position of the internal and external pressure heads 500 when they are subjected to 100gf. Specifically, the internal pressure head 300 is located at the standard position or the first zero point position. The external pressure head 500 starts from the second zero point position and continues until it is subjected to a pressure of 2.5gf, which is recorded as the third external position. The external pressure head 500 continues to move, and when it is subjected to a pressure of 100gf, it is recorded as the fourth external position. The position difference between the fourth external position and the third external position is then calculated.
