[0026] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0027] True Wireless Stereo (TWS) Bluetooth headsets abandon the wire connection method, so that users will not be tied down by wires when using the headset. The left and right earphones can work independently, which greatly improves convenience. TWS Bluetooth headsets generally have a charging box that is matched with the headset to store the headset and charge the headset at the same time.

[0028] At present, the charging box industry mainly uses large tooling and expensive acquisition and control systems for testing. The test terminal is large in size and needs to be pressed manually for automatic testing. It also requires expensive instrument acquisition and control, and the test results are not accurate enough.

[0029] In order to illustrate the technical solution of the present application, a specific embodiment is provided below for illustration.

[0030] Figure 1 A schematic diagram of the implementation flow of a charging box testing method provided in an embodiment of the present application is shown. The method can be applied to a terminal and is suitable for situations where the accuracy of the charging box test results needs to be improved.

[0031] Among them, the above-mentioned terminal can be a computer, a smart phone or other terminal.

[0032] Specifically, the above-mentioned charging box testing method may include the following steps S101 to S103.

[0033] Step S101, obtaining a first return value fed back after the spring of the charging box to be tested contacts the target earphone in a contour-like manner.

[0034] The charging box to be tested refers to the charging box that needs to be tested.

[0035] In an embodiment of the present application, a shrapnel is provided in the charging box to be tested, and the shrapnel in the charging box is used to contact with the contacts on the earphone and charge the earphone after contact, or interact with the earphone after contact to transmit data or instructions.

[0036] However, the study found that depending on the different designs of each charging box, the positions of the various shrapnel in the charging box may be different. If mismatched earphones are used to test the charging box under test, the test results will be inaccurate.

[0037] Therefore, in some embodiments of the present application, the terminal may control the target earphone to contact the spring of the charging box to be tested.

[0038] The earphone profiling refers to an earphone model for testing designed according to the structure of the earphone, and the earphone profiling is connected to the terminal so that the terminal can obtain information output by the charging box to be tested through the shrapnel through the earphone profiling. The target earphone profiling refers to an earphone profiling that matches the charging box to be tested.

[0039] In an embodiment of the present application, when the spring of the charging box to be tested contacts the target earphone, the charging box to be tested will feedback a first return value through the spring, and the first return value is feedback data calculated by the charging box to be tested according to the algorithm stored in itself.

[0040] After the test starts, the terminal may enter the search mode in advance. In the search mode, the terminal may obtain the first return value sent by the charging box to be tested through the shrapnel at a preset time interval.

[0041] It should be noted that in some embodiments of the present application, a preset time period can be set. If the terminal does not obtain the first return value within the preset time period, it means that there may be certain problems with the design of the charging box to be tested. For example, there is a large error between the height of the earphone accommodating slot of the charging box to be tested and the standard height of this type of charging box, or the shrapnel of the charging box to be tested itself cannot work normally. At this time, it can be determined that the test result of the charging box to be tested is that the charging box to be tested is defective.

[0042] Step S102: determining whether the spring piece is in accurate contact with the target earphone according to the first return value.

[0043] In the implementation manner of the present application, after obtaining the first return value fed back by the earphone to be tested through the spring, the terminal may analyze the first return value and determine whether the spring is in accurate contact with the target earphone according to the analysis result.

[0044] Specifically, in some embodiments of the present application, the above-mentioned determining whether the spring piece is in accurate contact with the target earphone according to the first return value may include: decrypting the first return value according to a preset decryption algorithm to obtain feedback information corresponding to the first return value; comparing the feedback information with preset standard feedback information, if the feedback information is the same as the standard feedback information, determining that the spring piece is in accurate contact with the target earphone; if the feedback information is different from the standard feedback information, determining that the spring piece is not in accurate contact with the target earphone.

[0045] Among them, the above-mentioned decryption algorithm is a decryption algorithm that matches the standard encryption algorithm of the charging box to be tested. In some embodiments of the present application, the charging box to be tested will be encrypted according to a pre-stored encryption algorithm to obtain a first return value. After obtaining the first return value fed back by the charging box to be tested, the above-mentioned terminal can decrypt according to a preset decryption algorithm to obtain feedback information. It can be understood that when the hardware and software of the charging box to be tested itself can work normally, and the internal encryption algorithm is the same as the standard encryption algorithm, the feedback information obtained by the above-mentioned terminal according to the first return value parsing should be the same as the standard feedback information. At this time, it can be determined that the shrapnel is in accurate contact with the target earphone. In the case where the hardware and software of the charging box to be tested itself cannot work properly, or the internal encryption algorithm is different from the standard encryption algorithm, the feedback information obtained by the above-mentioned terminal according to the first return value parsing should be different from the standard feedback information. At this time, it can be determined that the shrapnel is not in accurate contact with the target earphone.

[0046] Step S103, if the spring piece is in accurate contact with the target earphone, the charging box to be tested is tested to obtain a test result of the charging box to be tested.

[0047] In an embodiment of the present application, if the shrapnel is in accurate contact with the target earphone profile, it means that the charging box to be tested can interact normally with the target earphone profile that matches it. At this time, the shrapnel, charging interface and other test items of the charging box to be tested can be further tested to obtain the test result of the charging box to be tested.

[0048] In some embodiments of the present application, if the shrapnel cannot accurately contact the target earphone profile, it means that the charging box to be tested cannot interact normally with the target earphone profile that matches it. The reason may be that the positions of the shrapnel of the charging box to be tested are wrong, or there is a problem in the process of calculating or feedback of the first return value by the charging box to be tested. Therefore, it can be determined that the test result of the charging box to be tested is that the charging box to be tested is defective.

[0049] In the implementation mode of the present application, a first return value fed back after the shrapnel of the charging box to be tested is obtained after the shrapnel is in contour contact with the target earphone, and whether the shrapnel is in contour accurate contact with the target earphone is determined according to the first return value; if the shrapnel is in contour accurate contact with the target earphone, the charging box to be tested is tested to obtain a test result of the charging box to be tested, so that the charging result of the charging box to be tested is obtained under the condition that the shrapnel is in contour accurate contact with the target earphone, thereby avoiding erroneous test results obtained in the case of inaccurate contact.

[0050] For example, when the positions of the shrapnel in the charging box to be tested are different, that is, the order of the shrapnel is different from the order in the standard case, although the target earphone can normally contact each shrapnel in the charging box to be tested, the test result obtained based on the shrapnel in the wrong position is inaccurate. The solution provided in the present application can determine that the shrapnel is not in accurate contact with the target earphone based on the first return value in this case. At the same time, based on the first return value, the specific cause of the problem with the charging box to be tested can also be accurately determined, and the test result obtained is more accurate.

[0051] In an embodiment of the present application, after determining that the spring piece is in accurate contact with the target earphone, the test content of the charging box to be tested can be selected according to actual conditions.

[0052] Specifically, in some embodiments of the present application, the spring of the charging box to be tested includes a power spring. Figure 2 As shown, the above-mentioned testing of the charging box to be tested and obtaining the test result of the charging box to be tested may include the following steps S201 to S202.

[0053] Step S201, adjusting the load of the target earphone in contact with the power spring, and obtaining the output voltage of the power spring after each load adjustment.

[0054] The load is used to simulate the resistance of the earphone connected to the power spring.

[0055] In some embodiments of the present application, the load can be adjusted by a load control module connected to the target earphone profile. The terminal adjusts the load of the target earphone profile in contact with the power spring to simulate the situation after different earphones are inserted into the charging box to be tested.

[0056] Specifically, when different earphones are inserted into the charging box to be tested, the power spring of the charging box to be tested will have different output voltages. Therefore, in some embodiments of the present application, the output voltage of the power spring can be obtained after each load adjustment to determine whether the charging box to be tested works according to the preset conditions when different earphones are inserted.

[0057] Step S202, determining the test result of the charging box to be tested according to the output voltage and the standard output voltage corresponding to the load.

[0058] Among them, the above-mentioned adjustment of the load of the target earphone profiling in contact with the power spring sheet may include: setting the load of the target earphone profiling in contact with the power spring sheet to the load corresponding to the case where the earphone is not inserted into the charging box to be tested; or, setting the load of the target earphone profiling in contact with the power spring sheet to the load corresponding to the case where the charging box to be tested is inserted into a normal earphone; or, setting the load of the target earphone profiling in contact with the power spring sheet to the load corresponding to the case where the charging box to be tested is inserted into a damaged earphone.

[0059] Specifically, when the load is the load corresponding to the charging box to be tested without earphones inserted, that is, when the charging box to be tested is no-load, the output voltage of the power spring of the test charging box should be within the range of the standard output voltage (that is, the no-load voltage) corresponding to the no-load state.

[0060] For example, in some embodiments of the present application, the no-load voltage may range from 4.7 V to 5.2 V. In practical applications, the specific value of the no-load voltage range may be adjusted according to the charging box to be tested.

[0061] When the load is the load corresponding to the normal earphones inserted into the charging box to be tested, that is, when the normal earphones that are not damaged are inserted into the charging box to be tested, the output voltage of the power spring of the test charging box should be within the range of the standard output voltage (that is, the load voltage) corresponding to the normal earphones inserted.

[0062] For example, in some embodiments of the present application, the load corresponding to the above-mentioned charging box to be tested inserted into a normal headset may be 100 ohms, and the above-mentioned load voltage range may be 4.5 V to 5 V. In practical applications, the specific values ​​of the load corresponding to the above-mentioned charging box to be tested inserted into a normal headset and the load voltage range may be adjusted according to the charging box to be tested.

[0063] When the load is the load corresponding to the damaged earphone inserted into the charging box to be tested, that is, when the damaged earphone is inserted into the charging box to be tested, the charging box to be tested should trigger the overcurrent protection mechanism. In other words, when the damaged earphone is inserted into the charging box to be tested, the short-circuited earphone can trigger the overcurrent protection mechanism of the charging box to be tested. After the overcurrent protection mechanism is triggered, the output voltage of the power shrapnel of the test charging box should be within the range of the standard output voltage corresponding to the overcurrent protection state.

[0064] For example, in some embodiments of the present application, the load corresponding to the damaged earphone inserted into the above-mentioned charging box to be tested may be 30 ohms, and the range of the corresponding standard output voltage in the above-mentioned overcurrent protection state may be 0V to 1V. In practical applications, the specific values ​​of the load corresponding to the damaged earphone inserted into the above-mentioned charging box to be tested and the range of the load voltage and the range of the corresponding standard output voltage in the overcurrent protection state can be adjusted according to the charging box to be tested.

[0065] It should be noted that in order to avoid errors in the test results, the above-mentioned terminal can perform multiple tests under multiple loads to obtain the test results of the charging box to be tested.

[0066] In some embodiments of the present application, if the output voltage of the power shrapnel is within the range of the standard output voltage corresponding to the load, it can be determined that the test result of the charging box to be tested is that the power shrapnel of the charging box to be tested can work normally, and the charging box to be tested is a qualified charging box. If the output voltage of the power shrapnel is outside the range of the standard output voltage corresponding to the load, it can be determined that the test result of the charging box to be tested is that the power shrapnel of the charging box to be tested cannot work normally, and the charging box to be tested is an unqualified charging box. Moreover, according to the load used when the output voltage of the power shrapnel is outside the range of the standard output voltage corresponding to the load, it can be determined under what circumstances the charging box to be tested cannot work normally, that is, whether the charging box to be tested cannot work normally under no-load conditions, cannot work normally under load conditions, or whether the overcurrent protection mechanism of the charging box to be tested cannot work normally.

[0067] It should be noted that since there is a group of shrapnel in each of the two earphone accommodating grooves in the charging box to be tested, in the implementation mode of the present application, it is necessary to test the power shrapnel in the two earphone accommodating grooves separately. After completing the test of the power shrapnel in the two earphone accommodating grooves, the test result of the charging box to be tested is obtained.

[0068] In the implementation mode of the present application, by adjusting the load of the target earphone in contact with the power shrapnel, and obtaining the output voltage of the power shrapnel after each load adjustment, and determining the test result of the charging box to be tested according to the output voltage and the standard output voltage corresponding to the load, the performance of the power shrapnel can be tested when the shrapnel is in accurate contact with the target earphone, so the test result obtained is more accurate. In addition, based on different loads, the output voltage of the power shrapnel of the charging box to be tested in different states can be tested to determine whether the charging box to be tested can work normally in different states. The obtained test results are more targeted and can facilitate testers to track problems.

[0069] In some other embodiments of the present application, the spring of the charging box to be tested includes a data spring. Figure 3As shown, the above-mentioned testing of the charging box to be tested and obtaining the test result of the charging box to be tested may include the following steps S301 to S303.

[0070] Step S301, sending a query instruction to the data shrapnel.

[0071] Among them, the data shrapnel is a shrapnel different from the power shrapnel. Similarly, there is a data shrapnel in each of the two earphone accommodating slots in the charging box to be tested.

[0072] In some embodiments of the present application, the terminal may send a query command to the data shrapnel on either side. The query command is a serial port query command, which is used to instruct the charging box to be tested to feedback a second return value. The second return value is a return value calculated by a preset algorithm based on the first attribute information stored in the internal storage module of the charging box to be tested; or, it is a return value corresponding to the first attribute information obtained by querying the first attribute information stored in the internal storage module of the charging box to be tested.

[0073] Among them, the first attribute information may include the communication version of the charging box to be tested, information of the negative temperature coefficient (NTC) thermistor, power, check code, product serial number (Serial Number, SN) and other data.

[0074] Step S302, obtaining a second return value corresponding to the first attribute information of the charging box to be tested, which is generated by the charging box to be tested according to the query instruction, and obtaining the second attribute information pointed to by the second return value.

[0075] In some embodiments of the present application, the above-mentioned terminal can use the data spring to obtain the second return value corresponding to the first attribute information of the charging box to be tested generated by the charging box to be tested according to the query instruction, and then obtain the second attribute information pointed to by the second return value according to the second return value.

[0076] The second attribute information may be the second attribute information pointed to by the second return value queried by the terminal through table lookup, database query, etc.; or the corresponding second attribute information may be inferred from the second return value by the terminal according to a preset algorithm.

[0077] Step S303: compare the second attribute information with the attribute information of the standard charging box to obtain the test result of the charging box to be tested.

[0078] In some embodiments of the present application, by comparing the second attribute information with the attribute information of the standard charging box, if the second attribute information is the same as the attribute information of the standard charging box, it means that the data spring of the charging box to be tested can work normally. Therefore, the test result of the charging box to be tested can be determined as the charging box to be tested can work normally.

[0079] If the second attribute information is different from the attribute information of the standard charging box, it means that the data spring of the charging box to be tested cannot work normally, or there is a problem in the process of the charging box to be tested obtaining or feeding back the second return value. Therefore, the test result of the charging box to be tested can be determined as the charging box to be tested cannot work normally.

[0080] In an implementation manner of the present application, a query instruction is sent to the data shrapnel, a second return value corresponding to the first attribute information of the charging box to be tested and generated by the charging box to be tested according to the query instruction is obtained, and the second attribute information pointed to by the second return value is obtained, and then the second attribute information is compared with the attribute information of the standard charging box to be tested to obtain the test result of the charging box to be tested. The performance of the data shrapnel can be tested when the shrapnel is in accurate contact with the target earphone, so the test result obtained is more accurate.

[0081] In other embodiments of the present application, Figure 4 As shown, the above-mentioned testing of the charging box to be tested and obtaining the test result of the charging box to be tested may include the following steps S401 to S402.

[0082] Step S401, when the charging box to be tested is within a preset power range, a first charging voltage is input to the charging interface of the charging box to be tested.

[0083] Among them, the above-mentioned first charging voltage is equal to the standard charging voltage, and the standard charging voltage refers to the voltage input into the charging box to be tested when the charging box to be tested is charged through an external component under normal circumstances.

[0084] The above-mentioned power range refers to the interval of the power of the charging box to be tested during the test. In some embodiments of the present application, the above-mentioned power range can be 50% to 85% of the total power of the charging box to be tested. This power range is set in order to better ensure battery safety in the case of long-distance transportation.

[0085] In some embodiments of the present application, the terminal may select a corresponding interface to connect to the charging interface of the charging box to be tested according to the type of the charging interface, and input a first charging voltage to the charging box to be tested to charge the charging box to be tested.

[0086] For example, in some embodiments of the present application, if the charging interface of the charging box to be tested is a USB-C interface, the above-mentioned terminal can input a first charging voltage to the charging interface of the charging box to be tested through a USB-C charging cable, and the above-mentioned first charging voltage can be 5V.

[0087] Step S402, obtaining the charging current of the charging box to be tested, and determining the test result of the charging box to be tested according to the charging current.

[0088] In some embodiments of the present application, when the charging box to be tested is within the preset power range, since the first charging voltage is equal to the standard charging voltage, the charging box to be tested should be in a normal charging state, and the charging current of the charging box to be tested should be the same as the preset standard charging current. If the charging current of the charging box to be tested is the same as the preset standard charging current, it means that the charging box to be tested can work normally under normal charging conditions, so it can be determined that the test result of the charging box to be tested is that the charging interface of the charging box to be tested is normal and the charging box to be tested can work normally.

[0089] If the charging current of the charging box to be tested is different from the preset standard charging current, it means that the charging box to be tested cannot work normally under normal charging conditions. Therefore, it can be determined that the test result of the charging box to be tested is that the charging interface of the charging box to be tested cannot work normally.

[0090] In the implementation manner of the present application, when the charging box to be tested is within a preset power range, a first charging voltage is input to the charging interface of the charging box to be tested, and the charging current of the charging box to be tested is obtained, and the test result of the charging box to be tested is determined according to the charging current. When the spring fragment is in accurate contact with the target earphone in contour, the performance of the charging interface under normal charging conditions can be tested, and the test result obtained is more accurate.

[0091] In other embodiments of the present application, Figure 5 As shown, the above-mentioned testing of the charging box to be tested and obtaining the test result of the charging box to be tested may include the following steps S501 to S502.

[0092] Step S501, when the charging box to be tested is within a preset power range, a second charging voltage is input to the charging interface of the charging box to be tested.

[0093] Similarly, the terminal can select a corresponding interface to connect to the charging interface of the charging box to be tested according to the type of the charging interface, and input a second charging voltage to the charging box to be tested to charge the charging box to be tested.

[0094] The second charging voltage is greater than the standard charging voltage. The terminal inputs the second charging voltage to the charging interface of the charging box to be tested, which can simulate the situation of using a damaged charging head or charging cable to charge the charging box to be tested.

[0095] Step S502, obtaining a third charging voltage output by the charging box to be tested, and determining a test result of the charging box to be tested based on the third charging voltage.

[0096] Since the second charging voltage is greater than the standard charging voltage, the charging box to be tested will trigger the overvoltage protection mechanism. Therefore, in some embodiments of the present application, the terminal can obtain the third charging voltage output by the power spring of the charging box to be tested, and detect whether the third charging voltage is within the corresponding charging voltage range under the overvoltage protection condition to determine the test result of the charging box to be tested.

[0097] Taking the charging interface of the charging box to be tested as a USB-C interface as an example, the second charging voltage can be a 7V voltage. At this time, the third charging voltage output by the power spring of the charging box to be tested can be obtained, and it is determined whether the third charging voltage is within 0V to 1V.

[0098] If the third charging voltage is within the corresponding charging voltage range under overvoltage protection, it means that the charging box to be tested has triggered the overvoltage protection mechanism, disconnecting the voltage output of the power spring for charging the earphones, thereby protecting itself and the earphones. Therefore, the test result of the charging box to be tested can be determined as the overvoltage protection mechanism of the charging box to be tested can work normally.

[0099] If the third charging voltage is outside the corresponding charging voltage range under the overvoltage protection condition, it means that the charging box to be tested has not triggered the overvoltage protection mechanism, which may cause safety hazards in actual use. Therefore, the test result of the charging box to be tested can be determined as the overvoltage protection mechanism of the charging box to be tested cannot work normally, and the charging box to be tested is unqualified.

[0100] In the implementation mode of the present application, by inputting a second charging voltage to the charging interface of the charging box to be tested when the charging box to be tested is within a preset power range, and obtaining a third charging voltage output by the charging box to be tested, and determining the test result of the charging box to be tested based on the third charging voltage, the overvoltage protection mechanism of the charging interface under overvoltage charging conditions can be tested when the spring fragment is in accurate contact with the target earphone in shape, and the test result obtained is more accurate.

[0101] It should be noted that in order to make the test results more comprehensive and improve the accuracy of the test results, the terminal can perform the above steps on the charging box to be tested in sequence. Figures 2 to 5The test items described. This application does not limit the execution order of the test items, and the execution order can be adjusted by the tester according to the actual situation.

[0102] Figure 6 The schematic diagram of the structure of a terminal and a charging box to be tested provided by the present application is shown. The terminal includes a switching control module, a data communication module, a voltage and current acquisition module, a programmable power supply module, a shrapnel interface module and a target earphone profile. Among them, the shrapnel interface module can be connected to the switching control module, the data communication module, the voltage and current acquisition module and the programmable power supply through a bus. The switching control module, the data communication module, the voltage and current acquisition module and the programmable power supply can be connected to the terminal through a serial port, and the programmable power supply is connected to the charging interface at the bottom of the charging box to be tested through a charging cable (such as a USB-C cable). The left and right target earphone profiles are connected to the shrapnel interface module. And the left and right target earphone profiles are respectively in contact with the shrapnel in the earphone accommodating slot of the charging box to be tested. Among them, the shrapnel includes a data shrapnel and a power shrapnel.

[0103] The above terminal can sequentially perform the above Figures 2 to 5 The various test items described. Specifically, the power shrapnel of the charging box to be tested can be tested through the voltage and current acquisition module, and the output voltage of the power shrapnel output can be obtained by the target earphone profiling shrapnel interface module. The data shrapnel of the charging box to be tested can also be tested through the data communication module, and the second return value fed back by the data shrapnel can be obtained by the target earphone profiling shrapnel interface module. Alternatively, the charging interface of the charging box to be tested can be tested by a programmable power supply.

[0104] Based on the above terminals, it can be seen that the test terminal provided in this application does not require bulky tooling and fixtures, nor does it require expensive acquisition and control systems. It can automatically test the charging box to be tested, which can effectively reduce the cost of the enterprise.

[0105] In practical applications, since the above-mentioned terminal often needs to test different types of charging boxes to be tested, and the target earphone profiles corresponding to each charging box are often different. Therefore, in some embodiments of the present application, the above-mentioned terminal can be connected to multiple preset earphone profiles, and before testing the charging box to be tested, the target earphone profile that matches the charging box to be tested is screened out from the multiple preset earphone profiles.

[0106] Specifically, the terminal may select a target earphone profile that matches the charging box to be tested from a plurality of preset earphone profiles based on the earphone profile information of the earphone profile slot of the charging box to be tested and / or the shrapnel position information of the shrapnel of the charging box to be tested.

[0107] The above-mentioned receiving slot information may include information such as the height, width, shape, etc. of the earphone receiving slot, and the above-mentioned spring piece position information may include the position of the spring piece in the earphone receiving slot and the relative positions between the spring pieces.

[0108] Specifically, in some embodiments of the present application, the slot information of the earphone slot of the charging box to be tested and the spring clip position information of the spring clip of the charging box to be tested can be obtained by image recognition. The slot information and spring clip position information corresponding to the charging box to be tested can also be obtained according to the shape or model of the charging box to be tested.

[0109] According to the accommodating slot information of the earphone accommodating slot of the charging box to be tested and / or the shrapnel position information of the shrapnel of the charging box to be tested, it is possible to detect whether the shape of each preset earphone profile among multiple preset earphone profiles matches the earphone accommodating slot, and whether each contact point of each preset earphone profile matches the shrapnel position of each shrapnel, thereby filtering out the target earphone profile that matches the charging box to be tested from the multiple preset earphone profiles.

[0110] In an implementation manner of the present application, by selecting a target earphone profile that matches the charging box to be tested from multiple preset earphone profiles, when testing multiple charging boxes to be tested, a corresponding target earphone profile can be matched for the test of each charging box to be tested, thereby ensuring that the test results of each charging box to be tested are accurate test results.

[0111] In some other embodiments of the present application, the terminal may also control the preset earphone profiling to contact the spring sheet of the charging box, obtain a third return value fed back by the charging box after the spring sheet contacts the preset earphone profiling, and determine whether the spring sheet is in accurate contact with the preset earphone profiling according to the third return value; if the spring sheet is in accurate contact with the preset earphone profiling, the preset earphone profiling is determined as the target earphone profiling; if the spring sheet is not in accurate contact with the preset earphone profiling, the next preset earphone profiling is controlled to contact the spring sheet of the charging box, obtain a fourth return value fed back by the charging box after the spring sheet contacts the next preset earphone profiling, and determine whether the spring sheet is in accurate contact with the next preset earphone profiling according to the fourth return value, until a target earphone profiling is determined from multiple preset earphone profilings, or multiple preset earphone profilings are not in accurate contact with the spring sheet.

[0112] That is to say, in some other embodiments of the present application, the terminal can control multiple preset earphone profiles to contact the springs of the charging box to be tested in turn, and select the target earphone profile from the multiple preset earphone profiles according to the return value obtained after each contact.

[0113] It should be noted that, in actual applications, the above-mentioned multiple preset earphones should have target earphone profiles that match the charging box to be tested. If the above-mentioned multiple preset earphone profiles do not accurately contact the shrapnel, it means that the above-mentioned charging box to be tested cannot accurately contact the target earphone profile, and the reason may be that the positions of the shrapnel of the charging box to be tested are wrong, or there is a problem in the process of calculating or feeding back the first return value of the charging box to be tested. Therefore, it can be determined that the test result of the charging box to be tested is that there is a defect in the design of the charging box to be tested.

[0114] In the implementation manner of the present application, by controlling multiple preset earphone profiles to contact the spring pieces of the charging box to be tested in turn, and screening out the target earphone profile from the multiple preset earphone profiles according to the return value obtained after each contact, this implementation method can be applied to various types of charging boxes to be tested. Therefore, for actual application scenarios, a set of codes can be used to check a batch of different types of charging boxes to be tested, which can effectively reduce the workload of staff and reduce the processing burden of the above-mentioned terminals.
