[0028] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and effect of the present application clearer and more specific, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. The described embodiments are only possible technical implementations of the present application, not all possible implementations. Based on the embodiments in the present application, those skilled in the art can completely combine the embodiments of the present application to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present application.

[0030] The embodiments of the present application can be applied to the following scenarios:

[0031] First, the south is returning to the south or the north is heating in winter: the indoor temperature is high, the outdoor temperature is low, the temperature difference is relatively large, and the dew point range is relatively large; the relatively high humidity in the south is the main reason for the formation of condensation; the large temperature difference in the north is the main reason for the formation of condensation. During the process, the indoor door lock part is in a high temperature environment, and the warm and humid air enters the indoor lock cavity through the gap of the lock tongue and the gap on the lock surface (speaker hole, etc.); the outdoor door lock part is in a low temperature environment, and the low temperature environment makes the temperature of the lock shell outside the door and the PCBA (Printed Circuit Board Assembly) outside the door relatively low; when the high humidity air in the indoor door lock cavity reaches the door lock cavity outside the door, the dew point is formed due to the temperature difference, and dew condensation will form on the surface of the PCBA.

[0032] Second, the air-conditioning environment in the apartment in summer: the indoor temperature is low, the outdoor temperature is high, and the temperature difference is relatively large; and the space is relatively small and the air-conditioning is turned on for a long time. The long-term air-conditioning will make the condensation form more continuously, and the small space will make the temperature control relatively low. During the process, the outdoor door lock part is in a high temperature environment, and the warm and humid air enters the outdoor lock cavity through the gap of the lock tongue and the gap on the lock surface (speaker hole, etc.); the indoor door lock part is in a low temperature environment, and the low temperature environment makes the temperature of the lock shell and the PCBA inside the door relatively low; when the high-humidity air in the outdoor door lock cavity reaches the door lock cavity inside the door, the dew point is formed due to the temperature difference, and dew condensation will form on the surface of the PCBA.

[0033] In the prior art, when the test box simulates the change of ambient temperature, due to the temperature difference between the surface of the test product (such as a smart door lock) and the air inside the test box, when this temperature difference reaches a certain level, it is easy to form a dew point on the surface of the test product, thereby forming condensation. Specifically, a box is used, which is different from the scenes of the two environments inside and outside the smart lock door; condensation can only be formed during the time period of temperature change, and the time is relatively short and condensation cannot be sustained; the outer surface of the door lock is in direct contact with the air of the test box, and the air and the surface of the door lock are prone to form a temperature difference to produce condensation; the air flow in the cavity of the lock is not strong, the temperature change is not fast, and condensation is not easy to form on the PCBA surface; the air flow in the test box is strong, which will dry the surface of the test product. In other words, the current test box cannot simulate the actual scene of dew condensation on the user's smart door lock; and the embodiment of the present application can simulate the actual scene of the user to continuously form dew condensation, thereby improving the accuracy of the test.

[0034] The following describes the air tightness test method and the smart lock test equipment of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the smart lock in the related art mentioned above is prone to condensation inside the door lock under the temperature difference between indoor and outdoor conditions, and the existing test box cannot simulate the actual scene of dew condensation on the smart lock, resulting in low accuracy of the condensation test inside the smart lock, the present application provides an air tightness test method for a smart lock, in which the temperature and humidity in the two boxes are set to different levels to form a temperature difference, and the water vapor generated by the temperature difference circulates in the two boxes, thereby achieving the purpose of simulating the continuous formation of dew condensation in the actual scene of the user, thereby improving the accuracy of the smart lock test. As a result, the technical problem that the smart lock in the related art is prone to condensation inside the door lock under the temperature difference between indoor and outdoor conditions, and the existing test box cannot simulate the actual scene of dew condensation on the smart lock, resulting in low accuracy of the condensation test inside the smart lock is solved.

[0035] First, the following will be combined with the attached Figures 1 to 7 , the smart lock testing device of the embodiment of the present application is introduced.

[0036] like Figure 1 , Figure 2 and Figure 3As shown, an embodiment of the present application provides a smart lock testing device, which includes a first box 10, a second box 20 and a thermal insulation board 40, wherein the first box 10 and the second box 20 are connected via the thermal insulation board 40, and the thermal insulation board 40 is used to install a smart lock; a first temperature control component is provided on the first box 10, and a second temperature control component is provided on the second box 20, and the first temperature control component and the second temperature control component are both used to adjust the temperature in their respective boxes so that a temperature difference is formed between the first box 10 and the second box 20; one lock end of the smart lock is installed in the first box 10, and the other lock end of the smart lock is installed in the second box 20; the thermal insulation board 40 isolates the space in the first box 10 and the space in the second box 20, and the water vapor generated by the temperature difference circulates between the first box 10 and the second box 20.

[0037] The smart lock testing equipment isolates two independent boxes by setting a movable insulation board between them. The insulation board simulates the function of a door and the smart lock is installed on the insulation board. Different temperatures and humidities are set in the two boxes so that the water vapor formed by the two boxes can flow through the lock shell of the smart lock, thereby simulating the continuous formation of dew condensation in the actual scene of the user, thereby improving the accuracy of the smart lock test.

[0038] This application uses the principle that the temperature difference between the front and rear panels causes water vapor condensation, and circulates the water vapor at the high temperature and high humidity end (i.e., the second box 20) to the low temperature end (i.e., the first box 10) through a preset gap (ventilation groove 41). At the installation position of the smart door lock (i.e., on the insulation board 40), due to the temperature difference, the water vapor condenses on the door lock surface to form condensation. By accurately controlling the temperature and humidity conditions of the two boxes and the design of the ventilating groove 41, a continuous condensation environment that meets actual usage conditions can be simulated.

[0039] The dual-box design of the embodiment of the present application can simulate the temperature difference between the inside and outside of the user's door, realize a 1:1 replication of the user scenario in the laboratory, and realize the dew condensation phenomenon formed in the smart door lock of the user's home through the equipment, thereby improving the accuracy of the smart lock condensation test.

[0040] Specifically, the front lock of the smart lock is installed in the first box 10, and the rear lock of the smart lock is installed in the second box 20; or, the rear lock of the smart lock is installed in the first box 10, and the front lock of the smart lock is installed in the second box 20. That is, one lock end can be a front lock or a rear lock, and the corresponding other lock end can be a rear lock or a front lock.

[0041] The first box 10 of the embodiment of the present application simulates a colder outdoor environment and can independently control the temperature and humidity. The second box 20 simulates a warmer indoor environment and can also independently control the temperature and humidity. The two temperature boxes are connected through the middle insulation board 40, but are independently controlled. The insulation board 40 simulates the function of a door, and the door lock is installed on the insulation board 40 to separate the internal and external environments of the door lock. The insulation board 40 is designed to be easy to disassemble and install to adapt to different types of door locks. The extended part of the door frame lock tongue is hollowed out to facilitate the extension of the lock tongue and air circulation; a door gap can be opened on the insulation board 40 as needed to simulate the ventilation conditions of the actual door gap.

[0042] In one embodiment of the present application, the first temperature control component includes a refrigerator and a first sensing structure, the refrigerator is used to lower the spatial temperature in the first box 10, and the first sensing structure is used to detect the spatial temperature in the first box 10; the second temperature control component includes a heater and a second sensing structure, the heater is used to increase the spatial temperature in the second box 20, and the second sensing structure is used to detect the spatial temperature in the second box 20.

[0043] In one embodiment of the present application, the first temperature control component also includes a humidity dehumidifier, and the first sensing structure includes a first temperature sensor and a first humidity sensor; the second temperature control component also includes a humidity humidifier, and the second sensing structure includes a second temperature sensor and a second humidity sensor.

[0044] Specifically, the heater is used to increase the temperature of the environment, the refrigerator is used to lower the temperature of the environment, the humidifier is used to increase the humidity of the environment, and the dehumidifier is used to reduce the humidity of the environment; a fan or blower can also be set to promote air flow to accelerate the heating or cooling process, or in some cases for ventilation to reduce humidity.

[0045] In one embodiment of the present application, Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, air circulation is performed between the first box body 10 and the second box body 20 through the lock shell of the smart lock; a ventilation groove 41 is provided on the insulation board 40, and the ventilation groove 41 is used to connect the first box body 10 and the second box body 20, so that the high-temperature and high-humidity water vapor in the second box body 20 with different temperature and humidity can circulate through the ventilation groove 41.

[0046] It should be noted that air circulation is carried out through the lock shell, and the lock shell is, for example, a gap at the connection, or a speaker hole, etc.; the function of the ventilation groove 41 is to allow the high-temperature and high-humidity water vapor in one box (the second box 20) to flow to the other box (the first box 10) through the ventilation groove 41 because the four sides are closed.

[0047] In one embodiment of the present application, Figure 3 , Figure 4 and Figure 5 As shown, a hollow portion 42 is provided on the side of the insulation board 40, and the hollow portion 42 is used to connect with the lock tongue of the smart lock.

[0048] Furthermore, the partition door is designed according to different lock structures. The partition door structure is easy to disassemble and install, and the protruding part of the door frame lock tongue is a hollow part 42 (which allows the lock tongue to be extended normally, just like the normal door opening and closing state), which is convenient for different lock bodies and lock tongues and meets the air flow, and a ventilation groove 41 is opened next to the lock body behind one side to simulate the actual user's door gap.

[0049] In one embodiment of the present application, Figure 7 As shown, a box frame 30 is provided at the connection between the first box body 10 and the second box body 20. The box frame 30 has an opening. The insulation board 40 is connected to the box frame 30, and the insulation board 40 blocks the opening when in a closed state.

[0050] In one embodiment of the present application, the first handle of the smart lock is installed on the side of the thermal insulation plate 40 facing the first box body 10, and the second handle of the smart lock is installed on the side of the thermal insulation plate 40 facing the second box body 20. The thermal insulation plate 40 is turned into an open state by rotating the first handle or the second handle, and the thermal insulation plate 40 extends into the space of the first box body 10 or the second box body 20 in the open state.

[0051] Specifically, the thermal insulation board 40 is used to install the smart lock to be tested, which is designed according to the model and size of the door lock to ensure that the door lock can be installed securely.

[0052] In one embodiment of the present application, the first box body 10 is provided with a first door facing outward, and the space inside the first box body 10 is opened by the first door; the second box body 20 is provided with a second door facing outward, and the space inside the second box body 20 is opened by the second door.

[0053] In one embodiment of the present application, the smart lock testing device also includes a control unit, and the first temperature control component and the second temperature control component are respectively communicatively connected to the control unit.

[0054] In the embodiment of the present application, each box has a door that can be opened independently, two independent control systems for the two boxes, and a power switch button for the master control; and it meets the requirements of temperature test equipment and can achieve temperature and humidity adjustment control. The control unit independently controls the temperature and humidity conditions of the two temperature boxes, as well as the master control power switch, including components such as temperature and humidity sensors, controllers, and actuators, to achieve precise control.

[0055] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0056] The air tightness testing method of the smart lock described in the preferred embodiment of the present application is as follows: Figure 8 As shown, the air tightness testing method of the smart lock includes the following steps:

[0057] In step S101, a first parameter and a second parameter for testing the smart lock are obtained.

[0058] It should be noted that the executor of the test method of this embodiment is the control unit of the smart lock test device.

[0059] Specifically, install the smart lock on the middle partition (insulation board) of the smart lock test equipment to ensure that the door lock can be affected by two temperature chambers at the same time. Set the temperature and humidity parameters of the two temperature chambers according to the test purpose (electronic condensation protection test or lock shell air tightness test) and the test level.

[0060] In step S102, after the smart lock is installed on the insulation board and powered on, the first temperature control component is controlled to adjust the parameters in the first box to the first parameters, and the second temperature control component is controlled to modulate the parameters in the second box to the second parameters, wherein one lock end of the smart lock is located in the first box, and the other lock end of the smart lock is located in the second box.

[0061] In a possible implementation, the first parameter includes a first temperature and a first humidity, the second parameter includes a second temperature and a second humidity, the first temperature is less than the second temperature, and the first humidity is less than the second humidity. The first temperature control component is controlled to adjust the temperature in the first box to the first temperature and the humidity to the first humidity; the second temperature control component is controlled to adjust the temperature in the second box to the second temperature and the humidity to the second humidity.

[0062] Specifically, for thermostat A (i.e., the first box, simulating the outdoor environment), a lower temperature and moderate humidity, such as 15°C and 50%RH, are set. For thermostat B (i.e., the second box, simulating the indoor environment), a higher temperature and higher humidity, such as 35°C and 93%RH, are set.

[0063] In step S103, the operation information and power consumption data of the smart lock are obtained, wherein a temperature difference is formed between the first box under the first parameter and the second box under the second parameter, and water vapor generated by the temperature difference circulates between the first box and the second box.

[0064] Specifically, depending on the purpose of the test, choose whether to keep the door gap. If you are testing electronic condensation protection, keep the door gap to simulate normal air circulation; if you are testing the air tightness of the lock shell, close the door gap so that air can only circulate through the lock shell. Keep the door lock powered on to simulate the actual use of the user's home and observe whether an electrochemical reaction occurs.

[0065] In a possible implementation, the power consumption data includes the standby power consumption and operating power consumption of the smart lock. An operation instruction is sent to the smart lock to obtain operation information of the smart lock in response to the operation instruction, wherein the operation information includes the opening and closing state, password input attempt, fingerprint recognition attempt and network connection state; and the standby power consumption and operating power consumption of the smart lock in the test scenario are obtained.

[0066] Specifically, all operation information of the smart lock during the test is collected, including the lock's open and closed status, password input attempts, fingerprint recognition attempts, network connection status, etc. In addition, during the test, the power consumption data of the smart lock is continuously collected, including standby power consumption, operating power consumption, etc.

[0067] This application observes and records whether condensation forms on the PCBA surface inside the door lock and the sealing performance of the lock shell at different time periods. It also records information such as temperature and humidity changes and the working status of the door lock during the test.

[0068] In step S104, a test result of the smart lock is obtained according to the operation information and the power consumption data.

[0069] In a possible implementation, the test result includes good airtightness and unqualified airtightness. When the operation information is different from the expected behavior and the power consumption data exceeds the preset power consumption reference range, the airtightness of the smart lock is determined to be unqualified; when the operation information is consistent with the expected behavior and the power consumption data is within the preset power consumption reference range, the airtightness of the smart lock is determined to be good airtightness.

[0070] Specifically, the collected operation information is compared with the preset or expected behavior of the smart lock, which is based on the specifications of the smart lock or previous test data; if the operation information of the smart lock is consistent with the expected behavior, it means that its function is operating normally. If there is a difference, further analysis is required to determine whether it is an accidental error, software problem or hardware failure. Based on previous test data, the normal power consumption range of the smart lock under specific conditions is established, and the actual power consumption data is compared with the power consumption benchmark to evaluate whether there is an abnormality.

[0071] In one possible implementation, the operation information is compared with the corresponding expected behavior. If all operations are as expected, it is determined that the functional operation of the smart lock is normal; the power consumption data is compared with a preset power consumption benchmark. If the power consumption fluctuates within the preset power consumption benchmark range, it is determined that the power consumption of the smart lock is normal; if the smart lock is in a state where the power consumption operation is normal and the power consumption is normal, it is determined that the air tightness of the smart lock is good.

[0072] Specifically, start the test, ensure that the smart lock is correctly installed and powered on, send a series of operation instructions to the smart lock through the test equipment or remote control system (such as trying to open the lock, entering a password, using a fingerprint, etc.), record the response of the smart lock to each instruction, and compare the actual response with the expected response. If all operations are as expected, the function operates normally; otherwise, record any deviations and analyze them. Before the test starts, ensure that the smart lock is in the initial state (such as standby state), and use the power consumption monitoring equipment to record the power consumption changes of the smart lock during the test; adjust the power consumption baseline value (if necessary) according to the test scenario (such as temperature changes, operating frequency, etc.); compare the actual power consumption data with the power consumption baseline; if the actual power consumption fluctuates within the normal range, the power consumption is normal; if it exceeds the range, it may indicate that there is a power consumption abnormality, and the cause needs to be further investigated (such as battery aging, circuit failure, etc.).

[0073] Based on the preliminary test results, this application adjusts environmental parameters or conducts further tests. If you need to simulate the temperature and humidity conditions in different cities and seasons, adjust the temperature and humidity parameters of the test chamber. If you need to test the sealing of the front and rear lock shells, swap the installation positions of the front and rear locks. Based on the test time and observation records, evaluate the condensation protection performance of the door lock and the air tightness of the lock shell. Based on the test results, make improvement suggestions or optimize the product.

[0074] The air tightness test method of the above-mentioned smart lock of the present application is further described below through specific embodiments:

[0075] In the electronic condensation protection test:

[0076] Test purpose: Through the test, it is confirmed whether condensation will occur on the PCBA surface inside the lock housing. If there is no relevant protection condensation, electronic problems will be detected.

[0077] Test method:

[0078] Step S11, installing the door lock on the middle partition of the test chamber;

[0079] Step S12, the front lock of the thermostat A is installed, and the thermostat is set to 15°C and 50% RH to simulate the relatively cold outdoor environment;

[0080] Step S13, the rear lock installed in the thermostat B is set to 35°C and 93% RH to simulate a relatively warm indoor environment, and a door gap is reserved (simulating a normal door gap) to allow indoor air to flow better to the front lock;

[0081] Step S14: The door lock remains powered on. Electrochemical reactions are more likely to occur in the powered-on state, which is closer to the phenomenon in the user's home.

[0082] Step S21, adjusting the temperature and humidity of the test box according to the temperature and humidity conditions in different cities and seasons to be closer to the user's home scene;

[0083] Step S22: By swapping the installation positions of the front and rear locks, a scenario in which the indoor temperature is lower than the outdoor temperature in summer is simulated.

[0084] If condensation forms on the PCBA in the lock case in the low temperature incubator A, the air tightness test fails.

[0085] During the lock housing airtightness test:

[0086] Test purpose: To confirm whether there is any airtightness problem of the lock housing through the test.

[0087] Test method:

[0088] Step K11, install the door lock on the middle partition of the test chamber;

[0089] Step K12, install the front lock of the thermostat A, set the thermostat to 15℃ 50%RH environment, and simulate the cold outdoor environment;
