[0031] Embodiment 1

[0032] Figure 1 Schematic flowchart of a method for testing the locking and unlocking of a locking mechanism of a battery swapping station provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of testing the locking and unlocking control of the locking mechanism between the station control system of the battery swapping station and the battery pack. This method can be executed by a locking and unlocking test device for the locking mechanism of the battery swapping station. The locking and unlocking test device for the locking mechanism of the battery swapping station can be implemented in the form of hardware and / or software, and the locking and unlocking test device for the locking mechanism of the battery swapping station can be configured in an electronic device.

[0033] As Figure 1 shown, the method includes:

[0034] S110. Initialize the number of tests. In response to the power-taking signal, control the moving plate to rise from the waiting position to the working position, so that the lock body to be tested of the power exchange station locking mechanism is inserted into the lock pin to be tested of the power exchange station locking mechanism, and determine the locking state between the lock pin to be tested and the lock body to be tested.

[0035] Among them, the number of tests can be the number of times of the current unlocking and locking test. The power-taking signal can be an instruction to take out the battery pack from the power exchange station, that is, an instruction to take out the battery pack by locking through the locking mechanism. The power exchange station locking mechanism is the locking structure to be tested, which can include a lock pin to be tested and a lock body to be tested. The lock pin to be tested and the lock body to be tested are used in a matching manner and can realize the functions of locking and unlocking. The moving plate can be a plate structure that can reciprocate along a fixed direction and can carry the lock body to be tested. The moving plate is used to simulate the transportation of the battery pack by a Rail Guided Vehicle (RGV). The working position can be a position for fixing the lock pin to be tested. At the working position, the locking and unlocking of the power exchange station locking structure can be performed. The waiting position can be the position where the moving plate is located at the start of the test. Generally, the waiting position is below the working position. The locking state can be information indicating whether locking is successful, and can include successful locking and failed locking.

[0036] Specifically, at the start of the unlocking and locking test of the power exchange station locking mechanism, reset the number of tests, for example, initialize it to one, so that the number of tests can represent the current test times. Receive the power-taking signal, and control the moving plate to rise from the waiting position to the working position. At this time, the lock body to be tested carried on the moving plate can rise to the working position along with the moving plate, so that the lock body to be tested is combined with the lock pin to be tested fixed at the working position. Specifically, the lock body to be tested is inserted into the lock pin to be tested. Furthermore, it can be determined whether the locking of the power exchange station locking mechanism is completed after the lock body to be tested is inserted into the lock pin to be tested, and the locking state between the lock pin to be tested and the lock body to be tested is determined.

[0037] It should be noted that the insertion of the lock body to be tested into the lock pin to be tested is only the positional relationship between the two. After the insertion, determining whether the locking is completed is the purpose of the locking test.

[0038] S120. When the locking state is successful locking, in response to the power exchange signal, control the electromagnet to move from the preparation position to the magnetic attraction position, control the electromagnet to generate magnetism, control the moving plate to move downward, and determine the unlocking state between the lock pin to be tested and the lock body to be tested.

[0039] Among them, the battery swapping signal can be an instruction for replacing the battery pack, that is, an instruction to unlock the locking mechanism to replace the battery pack. An electromagnet is a device that generates electromagnetic force when energized, and is used to hold the lock body to be tested by magnetization and release the lock body to be tested by demagnetization. The preparation position can be the position where the electromagnet is initially placed, and the preparation position is at a second preset distance below the waiting position. It can be understood that in the initial state, the electromagnet is at a second preset distance below the moving plate. The magnetic attraction position can be the position where the electromagnet generates magnetism when energized and demagnetizes when powered off, and the magnetic attraction position is at a first preset distance below the working position. It can be understood that when performing the unlocking test, the electromagnet is at a first preset distance below the moving plate. It should be noted that the specific values of the first preset distance and the second preset distance can be set according to the actual situation and are not specifically limited in this embodiment. The unlocking state can be used to represent information on whether unlocking is successful, and can include unlocking success and unlocking failure.

[0040] Specifically, if the locking state is locking failure, there is no need to perform subsequent unlocking tests. At this time, it is necessary to manually or automatically lock the lock pin to be tested and the lock body to be tested to perform subsequent unlocking tests. If the locking state is locking success, subsequent unlocking tests are performed. Receive the battery swapping signal and control the electromagnet to move from the preparation position to the magnetic attraction position. When the electromagnet moves to the magnetic attraction position, the electromagnet is energized to generate magnetism, and at the same time, control the moving plate to move downward. At this time, if the unlocking is successful, the lock body to be tested will be separated from the lock pin to be tested under the action of the magnetic force and move downward with the moving plate. If the unlocking fails, when the moving plate moves downward, there is no lock body to be tested on the moving plate. Therefore, the unlocking state between the lock pin to be tested and the lock body to be tested can be further determined.

[0041] S130. Determine the locking and unlocking test results corresponding to the test times according to the locking state and the unlocking state, and update the test times.

[0042] Among them, the locking and unlocking test results can be an integration of the locking result and the unlocking result, such as locking success + unlocking success, locking failure + unlocking success, etc., or can be such as locking and unlocking failure or locking and unlocking success.

[0043] Specifically, after determining the locking state through the locking test and the unlocking state through the unlocking test, the locking state and the unlocking state can be integrated, and the obtained result is the locking and unlocking test result corresponding to the test times. Furthermore, update the test times, specifically, the test times can be incremented by one to enter the next locking and unlocking test of the lock structure of the battery swapping station, and record the test times of the next test.

[0044] Optionally, before updating the number of tests, it can be first determined whether the number of tests meets the test requirements, that is, whether it reaches the preset number, so as to determine whether to update the number of tests and conduct the next test.

[0045] Specifically, it can be:

[0046] When the number of tests is less than the preset number, return and execute the operation of controlling the moving plate to rise from the waiting position to the working position in response to the power-taking signal.

[0047] Among them, the preset number can be the number of times set in advance for the unlocking and locking tests of the locking mechanism of the swapping station for a set of lock pins to be tested and lock bodies to be tested. The specific value can be set according to actual needs and is not specifically limited in this embodiment.

[0048] Specifically, when the number of tests is less than the preset number, it indicates that the number of tests is insufficient and continuous testing is still required. Therefore, continue to execute the operation of controlling the moving plate to rise from the waiting position to the working position in response to the power-taking signal to conduct the next unlocking and locking test.

[0049] When the number of tests is equal to the preset number, determine the total test result of the locking mechanism of the swapping station according to the results of each unlocking and locking test.

[0050] Among them, the total test result can be the test result of the locking mechanism of the swapping station obtained by synthesizing the results of each unlocking and locking test, and can include passing the test and failing the test, etc.

[0051] Specifically, when the number of tests is equal to the preset number, it indicates that the number of tests has reached the test requirements and the test can be stopped. Moreover, based on the unlocking and locking test results corresponding to each test number, a comprehensive analysis is conducted to determine the total test result of the locking mechanism of the swapping station.

[0052] Exemplarily, the total test result of the locking mechanism of the swapping station can be determined according to the success ratio in the unlocking and locking test results. For example: determine the success ratio according to the results of each unlocking and locking test. If the success ratio is greater than or equal to the preset ratio, the total test result of the locking mechanism of the swapping station is passing the test; if the success ratio is less than the preset ratio, the total test result of the locking mechanism of the swapping station is failing the test. Of course, the total test result can also be determined by other methods, which will not be elaborated in this embodiment.

[0053] In the technical solution of the embodiment of the present invention, by initializing the number of test times, in response to the power-taking signal, the moving plate is controlled to rise from the waiting position to the working position, so that the to-be-tested lock body of the locking mechanism of the battery swapping station is inserted into the to-be-tested lock pin of the locking mechanism of the battery swapping station, and the locking state between the to-be-tested lock pin and the to-be-tested lock body is determined. In the case where the locking state is successful locking, in response to the battery swapping signal, the electromagnet is controlled to move from the preparation position to the magnetic attraction position, the electromagnet is controlled to generate magnetism, the moving plate is controlled to move downward, and the unlocking state between the to-be-tested lock pin and the to-be-tested lock body is determined. According to the locking state and the unlocking state, the locking and unlocking test result corresponding to the number of test times is determined, and the number of test times is updated, which solves the problems of long locking and unlocking test cycles of the locking mechanism of the battery swapping station and poor test compatibility for different vehicle models, realizes the improvement of the convenience of the locking and unlocking test of the locking mechanism of the battery swapping station, and moreover, improves the test compatibility of the electromagnetic locking mechanisms of different vehicle models.

[0054] Embodiment 2

[0055] Figure 2 It is a schematic flowchart of a method for testing the locking and unlocking of a locking mechanism of a battery swapping station provided by Embodiment 2 of the present invention. On the basis of the above embodiments, for the specific content of the determination method of the locking state and the unlocking state, reference can be made to the detailed description of this technical solution. Among them, the explanations of the same or corresponding terms as those in the above embodiments will not be repeated here.

[0056] As Figure 2 shown, the method includes:

[0057] S210. Initialize the number of test times, and in response to the power-taking signal, control the moving plate to rise from the waiting position to the working position, so that the to-be-tested lock body of the locking mechanism of the battery swapping station is inserted into the to-be-tested lock pin of the locking mechanism of the battery swapping station.

[0058] S220. Control the moving plate to descend from the working position to the downward pull position.

[0059] Among them, the downward pull position is a position below the working position, which is used to judge the locking state and can also be used to judge the unlocking state in the subsequent unlocking test.

[0060] Specifically, during the locking test, control the moving plate to descend from the working position to the downward pull position. If the locking is successful, the to-be-tested lock body will not move to the downward pull position along with the moving plate. If the locking fails, the to-be-tested lock body will move to the downward pull position along with the moving plate.

[0061] S230. Obtain a first proximity signal based on a preset proximity sensor, and determine the locking state according to the first proximity signal.

[0062] Among them, the proximity sensor is used to detect whether the lock body to be tested moves to the downward position following the moving plate. The proximity sensor can be a magnetic proximity sensor. The proximity sensor is set at a third preset distance above the downward position to detect whether the lock body to be tested is carried on the moving plate. The first proximity signal can be the induction signal of the proximity sensor after the moving plate descends to the downward position during the locking test.

[0063] Specifically, after the moving plate descends from the working position to the downward position, obtain the induction signal of the proximity sensor, which is the first proximity signal. Determine whether the proximity sensor is blocked according to the first proximity signal, which can be understood as whether it is blocked by the lock body to be tested carried on the moving plate. If it is blocked, it indicates that the lock body to be tested moves down with the moving plate, and determine that the locking state is locking failure; if it is not blocked, it indicates that the lock body to be tested is locked with the lock pin to be tested and does not move down with the moving plate, and determine that the locking state is locking success.

[0064] S240. Control the moving plate to rise from the downward position to the working position.

[0065] Specifically, raise the moving plate from the downward position to the working position to facilitate subsequent unlocking tests.

[0066] S250. When the locking state is locking success, in response to the power change signal, control the electromagnet to move from the ready position to the magnetic attraction position and control the electromagnet to generate magnetism.

[0067] S260. Control the moving plate to descend from the working position to the downward position.

[0068] Specifically, during the unlocking test, control the moving plate to descend from the working position to the downward position. If the unlocking fails, the lock body to be tested will not move to the downward position with the moving plate. If the unlocking is successful, the lock body to be tested will move to the downward position with the moving plate.

[0069] S270. Obtain the second proximity signal based on the proximity sensor and determine the unlocking state according to the second proximity signal.

[0070] Among them, the second proximity signal can be the induction signal of the proximity sensor after the moving plate descends to the downward position during the unlocking test.

[0071] Specifically, after the moving plate descends from the working position to the lowered position, the induction signal of the proximity sensor is obtained, which is the second proximity signal. It can be determined whether the proximity sensor is blocked according to the second proximity signal, which can be understood as whether it is blocked by the lock body to be tested carried on the moving plate. If it is blocked, it indicates that the lock body to be tested has disengaged from the lock pin to be tested and has descended with the moving plate, and it is determined that the unlocking state is successful; if it is not blocked, it indicates that the lock body to be tested and the lock pin to be tested are still in the locked state and have not descended with the moving plate, and it is determined that the unlocking state is failed.

[0072] S280. Control the electromagnet to demagnetize, control the electromagnet to move from the magnetic attraction position to the preparation position, and control the moving plate to descend from the lowered position to the waiting position.

[0073] Specifically, in order to facilitate the next unlocking and locking test, it is necessary to control the electromagnet and the moving plate to return to the initial state. First, the electromagnet can be controlled to power off and demagnetize, and the electromagnet is controlled to move from the magnetic attraction position to the preparation position to wait for the next unlocking test. Furthermore, the moving plate is controlled to descend from the lowered position to the waiting position to wait for the next unlocking and locking test.

[0074] S290. Determine the unlocking and locking test results corresponding to the test times according to the locking state and the unlocking state, and update the test times.

[0075] Optionally, the electromagnet is controlled by a relay connected to the electromagnet. When the relay is closed, the electromagnet is powered on to generate magnetism. When the relay is open, the electromagnet is powered off and demagnetized.

[0076] Figure 3 It is a schematic flowchart of another unlocking and locking test method for the locking mechanism of the battery swapping station provided by the second embodiment of the present invention. As Figure 3 shown, the method includes:

[0077] 1) Power on the electromagnetic lock unlocking and locking test bench, complete initialization, and the magnetic attraction Z-axis (moving plate) is in the waiting position.

[0078] Specifically, the moving plate can be used to simulate the RGV carrying the battery pack to the specified position. The structural schematic diagrams of the electromagnetic lock unlocking and locking test bench and the control system are as Figure 4 shown, and the cross-sectional top view of the electromagnetic lock unlocking and locking test bench is as Figure 5 shown. According to Figure 4 and Figure 5 it can be seen that the unlocking and locking tests can be carried out for two sets of locking mechanisms respectively at the same time. Figure 5 The left electromagnet and the left magnetic attraction proximity switch in are used to test the left locking mechanism, and the right electromagnet and the right magnetic attraction proximity switch are used to test the right locking mechanism.

[0079] 2) The control system controls the motor to operate, driving the magnetic adsorption Z-axis to rise to the working position (working location), that is, the magnetic adsorption Z-axis rises to simulate jacking up the battery pack, so that the locking pin (the locking pin to be tested) is inserted into the lock body (the lock body to be tested) to complete locking.

[0080] 3) The control system controls the motor to operate, driving the magnetic adsorption Z-axis to descend to the pulling-down position (pulling-down location). The magnetic adsorption proximity sensor is exposed, and the proximity signal (the first proximity signal) feeds back the state (locking state). If there is no signal, it is detected that the locking is successful.

[0081] 4) When the control system receives the signal of successful locking, it controls the motor to operate and drives the magnetic adsorption Z-axis to return to the working position.

[0082] 5) The control system controls the motor to operate, and the magnetic adsorption push rod drives the electromagnet to rise to the limited position (magnetic adsorption position).

[0083] Among them, the magnetic adsorption push rod is a component that pushes or pulls the electromagnet to move.

[0084] 6) The control system controls the relay to close, the electromagnet is powered on, and the suction is completed, that is, the lock body moves and separates from the locking pin under the action of magnetic force to complete unlocking.

[0085] 7) The control system controls the motor to operate, driving the magnetic adsorption Z-axis to descend to the pulling-down position. The magnetic adsorption proximity sensor is blocked, and the proximity signal (the second proximity signal) feeds back the state (unlocking state). If there is a signal, it is detected that the unlocking is successful.

[0086] 8) The control system receives the signal of successful unlocking.

[0087] 9) The control system controls the relay to disconnect, the electromagnet is powered off and demagnetized and descends, and the magnetic adsorption Z-axis returns to the waiting position. The counter of the control system synchronously counts to complete the recording of the test times.

[0088] Through 1)-9), a locking and unlocking test of the locking mechanism of the battery swapping station is realized, and it is synchronously detected whether the locking and unlocking are successful. Through multiple locking and unlocking tests of the locking mechanism of the battery swapping station, the test results (total test results) of the locking mechanism of the battery swapping station can be detected.

[0089] In the technical solution of the embodiment of the present invention, by initializing the number of tests, in response to the power-taking signal, the moving plate is controlled to rise from the waiting position to the working position, so that the lock body to be tested of the locking mechanism of the battery swapping station is inserted into the lock pin to be tested of the locking mechanism of the battery swapping station. The moving plate is controlled to descend from the working position to the pulling-down position, a first proximity signal is obtained based on a preset proximity sensor, and the locking state is determined according to the first proximity signal. The moving plate is controlled to rise from the pulling-down position to the working position. When the locking state is successful locking, in response to the battery swapping signal, the electromagnet is controlled to move from the preparation position to the magnetic attraction position, the electromagnet is controlled to generate magnetism, the moving plate is controlled to descend from the working position to the pulling-down position, a second proximity signal is obtained based on the proximity sensor, and the unlocking state is determined according to the second proximity signal. The electromagnet is demagnetized, the electromagnet is controlled to move from the magnetic attraction position to the preparation position, the moving plate is controlled to descend from the pulling-down position to the waiting position, and according to the locking state and the unlocking state, the locking and unlocking test result corresponding to the number of tests is determined, and the number of tests is updated, solving the problem that it is difficult to judge the locking state and the unlocking state during the locking and unlocking test of the locking mechanism, and achieving the effect of improving the convenience and accuracy of judging the locking state and the unlocking state.

As Figure 6 shown, the device includes: a locking test module 310, an unlocking test module 320, and a test result determination module 330.
