Background Technology

[0002] During charging, the electronic lock needs to lock the charging gun's locking lever to ensure a reliable connection between the charging gun and the electric vehicle's socket. This prevents the charging gun from being pulled out easily, thus preventing arcing caused by the charging gun separating from the vehicle socket during high-current charging, which could result in personal injury and vehicle damage.

[0003] However, with increased use of the charging gun, the locking lever may become damaged, preventing the vehicle from reliably locking to the charging gun while it is charging. This could lead to the risk of the charging gun being forcibly pulled out or automatically detaching during charging. Therefore, ensuring the safe use of the charging gun, and thus the safe charging of the vehicle, has become a pressing issue that needs to be addressed. Summary of the Invention

[0042] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0043] During charging, the electronic lock needs to lock the charging gun's locking lever to ensure a reliable connection between the charging gun and the electric vehicle's socket. This prevents the charging gun from being pulled out easily, thus preventing arcing caused by the charging gun separating from the vehicle socket during high-current charging, which could result in personal injury and vehicle damage.

[0044] However, as the charging gun is used more often, the charging gun locking lever may be damaged, causing the vehicle to be unable to reliably lock with the charging gun when the charging station is charging the vehicle. This results in the risk that the charging gun may be forcibly pulled out or automatically detached during charging.

[0045] Damaged locking levers prevent a reliable lock between the charging gun and the vehicle's charging socket. If the charging gun is removed during charging, it can cause arcing, endangering personal safety and property. Furthermore, if the charging gun is not fully inserted due to a damaged locking lever, overheating at the charging gun and vehicle socket terminals can occur, leading to annealing of the vehicle's terminals and loss of spring elasticity in the socket. Subsequent charging in the vehicle socket will then result in excessive resistance due to larger gaps between terminals, causing overheating and terminal burning. With the increasing current demands of vehicles, the current connecting the charging gun and socket can reach 600-1000A during charging. Arcing from energized insertion or removal can be fatal. If workers or users are unaware of the damaged locking lever and operate the charging gun, it can easily endanger personal safety and property. Therefore, ensuring the safe use of charging guns and thus ensuring vehicle charging safety is a pressing issue that needs to be addressed.

[0046] To address the above problems, this application provides a charging gun detection method, which will be described in detail below:

[0047] Please see Figure 1 and Figure 2 This application provides a charging gun detection method, which is applied to an electrical device 100. The method includes:

[0048] Step 011: The first detection device 20 of the electrical equipment 100 detects the engagement depth of the locking rod 201 of the charging gun 200 and the joint 30 of the electrical equipment 100, the joint 30 being used to engage with the locking rod 201 of the charging gun 200.

[0049] Specifically, the charging gun 200 is an essential device for charging electric vehicles; its main function is to transfer electricity from the power source to the car battery. Please refer to... Figure 3 The charging gun 200 includes a charging gun body 202 and a locking lever 201. The charging gun body 202 includes an area within the charging gun 200 that can be connected to a vehicle or a charging station, specifically the plug end of the charging gun 200. The charging gun body 202 can also supply power to the vehicle; after being inserted into the vehicle, the charging gun body 202 can connect to and charge the vehicle's battery. The locking lever 201 is used to lock the charging gun 200 when it is connected to the vehicle, preventing the charging gun body 202 from being pulled out of the vehicle during charging, thus avoiding live plugging and unplugging. The locking lever 201 includes a locking lever body 2011 and a locking lever end 2012, which are connected together. The locking lever body 2011 is typically designed as a straight lever for easy insertion and locking. The locking lever end 2012 primarily functions to insert, lock, and unlock. The insertion function refers to the ability of the locking lever 201 to be smoothly inserted into the object being locked; the locking function refers to the ability of the locking lever 201 to be securely fixed in the object being locked after insertion, preventing it from being easily pulled out; the unlocking function refers to the ability of the locking lever 201 to be smoothly pulled out or unlocked when needed. The locking lever body 2011 is used to connect with other areas of the charging gun, and the locking lever end 2012 is used to engage with the joint 30.

[0050] Electrical equipment 100 refers to equipment that requires electrical energy conversion to operate normally. Electrical equipment 100 can be either a power-consuming device or a power-supplying device. Therefore, electrical equipment 100 can be equipment equipped with a charging gun 200, or equipment that uses the charging gun 200 for charging. For example, electrical equipment 100 is... Figure 4 The vehicle shown is an electrical device or equipment 100 that can be charged using the charging gun 200. Figure 6 The charging piles shown are equipped with power supply equipment such as charging guns 200.

[0051] The electrical equipment 100 is provided with a receiving groove 40 for accommodating the charging gun body 202 and a joint 30 for accommodating the locking rod 201 of the charging gun 200, such as Figure 4 and Figure 6 , Figure 4 The socket 50 for the vehicle has a receiving slot 40 and a connecting part 30 inside. Figure 6The charging station has a socket with a receiving groove 40 and a connecting part 30 inside. When the charging gun body 202 is engaged with the receiving groove 40, the locking rod end 2012 of the locking rod 201 is also engaged with the connecting part 30. The engagement depth between the locking rod 201 and the connecting part 30 is the length of the overlapping area of ​​the locking rod end 2012 and the connecting part 30 along the extension direction of the connecting part 30. The engagement depth after the locking rod end 2012 and the connecting part 30 are engaged affects the engagement strength between the two.

[0052] In some embodiments, the joint 30 is a receiving groove, for example... Figure 2 (a) The receiving groove can accommodate the locking rod 201, which can extend into the receiving groove. At this time, the engagement depth between the locking rod 201 and the engaging portion 30 is the depth to which the locking rod 201 extends into the engaging portion 30. In other embodiments, for example... Figure 2 (b) The joint 30 may be a boss, and the locking rod 201 may abut against the boss. At this time, the engagement depth between the locking rod 201 and the joint 30 is the overlap length between the locking rod 201 and the joint 30 along the extension direction of the joint 30.

[0053] The charging gun 200 is connected to the vehicle socket 50 as follows: Figure 5 As shown. Please refer to... Figure 2 The shallower the engagement depth, the worse the engagement effect, and the easier it is for the locking rod 201 to detach from the joint 30 after the user shakes the charging gun 200. The deeper the engagement depth, the better the engagement effect between the locking rod 201 and the joint 30, and no matter how the user shakes the charging gun 200, the locking rod 201 cannot detach from the joint 30, thus ensuring the safety of the charging gun 200.

[0054] Damage to the locking rod 201 refers to the breakage or deformation of the area where the locking rod 201 and the joint 30 are joined. When the area where the locking rod 201 and the joint 30 are joined is broken or deformed, the joint depth between the locking rod 201 and the joint 30 will be reduced, resulting in a poorer joint effect between the locking rod 201 and the joint 30. As a result, after the charging gun 200 is inserted into the vehicle, the locking rod 201 is difficult to lock reliably, leading to lower safety of the charging gun 200.

[0055] The electrical equipment 100 may also be provided with a first detection device 20, which can detect the engagement depth of the locking rod 201 and the joint 30. For example, the first detection device 20 can directly detect the length of the locking rod 201 extending into the joint 30 to determine the engagement depth. As another example, the first detection device 20 can detect the distance between the end of the locking rod 201 facing the bottom of the joint 30 and the bottom of the joint 30, and then combine this with the depth of the joint 30 to determine the engagement depth.

[0056] In one embodiment, the first detection device 20 is a microswitch containing a spring and mounted inside the junction 30. When the charging gun 200 is installed on the electrical equipment 100, the locking lever 201 extends into the junction 30 and contacts the microswitch. The locking lever 201 presses the microswitch, triggering it to close and pushing the top of the microswitch towards the bottom of the junction 30 until the charging gun 200 is fully connected to the electrical equipment 100. The travel of the microswitch at this point represents the distance between the top of the locking lever 201 (i.e., the end of the locking lever 201 facing the bottom of the junction 30) and the bottom of the junction 30. Therefore, the distance between the end of the locking lever 201 facing the bottom of the engagement portion 30 and the bottom of the engagement portion 30 can characterize the engagement depth of the locking lever 201 and the engagement portion 30. The total depth of the engagement portion 30, and the difference between the total depth of the engagement portion 30 and the distance between the end of the locking lever 201 facing the bottom of the engagement portion 30 and the bottom of the engagement portion 30, is the depth to which the locking lever 201 extends into the engagement portion 30, that is, the engagement depth of the locking lever 201 and the engagement portion 30. Therefore, the engagement depth of the locking lever 201 and the engagement portion 30 can be detected based on the stroke of the microswitch.

[0057] In some embodiments, the electrical equipment 100 is a vehicle and / or a charging pile. A first detection device 20 can be installed on the vehicle, the charging pile, or both simultaneously. This allows the first detection device 20 to detect whether the locking lever 201 is damaged when the charging gun 200 is inserted into the vehicle or returned to the charging pile, facilitating timely detection of any damage to the locking lever 201. Furthermore, regardless of whether the first detection device 20 is installed on the vehicle or the charging pile, it can determine the risk of live insertion / removal during the early stages of the charging process, allowing for proactive assessment of the extent of damage to the locking lever 201 and subsequent execution strategies.

[0058] Step 012: Determine the damage information of the locking rod 201 based on the engagement depth.

[0059] Specifically, the damage information of the locking rod 201 can be determined based on the engagement depth detected by the first detection device 20. For example, a preset depth threshold can be determined based on the minimum engagement depth between the locking rod 201 and the engagement portion 30 when they can reliably lock together. If the engagement depth is less than the preset depth threshold, the damage information can be confirmed as damage to the locking rod 201; if the engagement depth is greater than the preset depth threshold, the damage information can be confirmed as no damage to the locking rod 201.

[0060] Thus, a first detection device 20 can be installed in the electrical equipment 100 to detect the charging gun 200, ensuring that damage to the locking rod 201 can be detected in a timely manner. This facilitates the timely issuance of an alarm when the locking rod 201 is damaged, so as to inform maintenance personnel to repair or replace the locking rod 201 as soon as possible, or to remind users that when using the charging gun 200 to charge the vehicle, it is strictly forbidden to touch or pull out the charging gun 200 during the charging process. This improves the safety of the charging gun 200 and ensures personal and property safety. It also prevents the charging gun 200 and the vehicle socket terminals from overheating, which could cause annealing of the vehicle seat terminals, failure of the spring elasticity of the vehicle socket terminals, excessive resistance due to large gaps between terminals during subsequent charging of the vehicle socket, overheating and terminal burning problems, and arcing problems caused by hot plugging and unplugging.

[0061] The charging gun detection method of this application includes an electrical device 100 with a coupling portion 30 for housing the locking rod 201 of the charging gun 200 and a first detection device 20. The first detection device 20 is used to detect the coupling depth between the locking rod 201 and the coupling portion 30. When the locking rod 201 is damaged, the coupling depth between the locking rod 201 and the coupling portion 30 will decrease, causing the locking rod 201 and the coupling portion 30 to fail to lock effectively and easily detach from the coupling portion 30. Therefore, the damage information of the locking rod 201 can be determined based on the coupling depth detected by the first detection device 20. Thus, after the charging gun 200 is placed in the electrical device 100, the first detection device 20 on the electrical device 100 can be used to detect whether the locking rod 201 is damaged, ensuring that the damage to the locking rod 201 can be detected in a timely manner, facilitating the timely issuance of an alarm when the locking rod 201 is damaged, thereby improving the safety of the charging gun 200 and ensuring the charging safety of the vehicle.

[0062] Please see Figure 2 and Figure 7 In some embodiments, the damage information includes whether the locking bar is damaged. Step 012: Determine the damage information of the locking bar 201 based on the engagement depth, including:

[0063] Step 0121: Determine whether the locking rod 201 is damaged based on the engagement depth and the preset depth threshold.

[0064] Specifically, the preset depth threshold is the minimum engagement depth between the locking rod 201 and the connecting portion 30, ensuring reliable locking between them, i.e., preventing the locking rod 201 from easily detaching from the connecting portion 30 during charging. Therefore, whether the locking rod 201 is damaged can be determined based on the engagement depth and the preset depth threshold. If the engagement depth is less than or equal to the preset depth threshold, the lock rod 201 is confirmed to be damaged; if the engagement depth is greater than the preset depth threshold, the lock rod 201 is confirmed to be undamaged.

[0065] In this way, it is possible to accurately determine whether the lock bar is damaged based on the engagement depth and the preset depth threshold.

[0066] Please see Figure 2 and Figure 8 In some embodiments, the charging gun detection method further includes:

[0067] Step 013: If the damage information includes damage to the locking lever 201, issue an alarm and restrict the use of the charging gun 200.

[0068] Specifically, if the damage information includes a damaged locking lever 201, it can be assumed that a reliable lock cannot be achieved between the locking lever 201 and the vehicle, resulting in lower safety for the charging gun 200. In this case, an alarm can be issued to inform maintenance personnel or users that the locking lever 201 of the charging gun 200 has been damaged, requiring caution when using the charging gun 200 or prohibiting its use altogether. An alarm can also be issued to notify maintenance personnel to replace or repair the charging station / charging gun 200. Simultaneously, the use of the charging gun 200 can be restricted, for example, by limiting the charging current of the charging gun 200 to below a certain safety threshold, or by directly prohibiting its use. In this way, when a damaged locking lever 201 is confirmed, an alarm can be issued promptly and the use of the charging gun 200 can be restricted, thereby improving the safety of the charging gun 200.

[0069] If the damage information indicates that the locking lever 201 is not damaged, it can be assumed that the locking lever 201 can reliably lock with the vehicle, and the charging gun 200 has a high degree of safety. There is no need to restrict the use of the charging gun 200, nor is there any need to make a loud noise.

[0070] There are various ways to issue an alarm, and no restrictions are placed here. For example, it can be alerted through the display screen of the electrical equipment 100, such as the display screen of the charging pile or the vehicle, or through the indicator light of the electrical equipment 100, or through the voice prompt of the electrical equipment 100, or through a mini-program, app or SMS push.

[0071] In some implementations, different execution strategies may be used for different severity levels.

[0072] In one embodiment, if the damage level is Level 1, the locking lever 201 can be considered undamaged or slightly damaged, and the charger is considered to be relatively safe to use. Therefore, in the case of Level 1 damage, there is no need to additionally limit the charging current of the charging station. In this case, the charging station can charge the vehicle with its maximum charging current without issuing any alarms.

[0073] Please see Figure 2 and Figure 9In some implementations, the damage information includes a severity level. Step 012: Determine the damage information of the locking bar 201 based on the engagement depth, including:

[0074] Step 0122: Based on the engagement depth detected by the first detection device 20 and multiple preset ranges, determine the degree level of the locking rod 201 of the charging gun 200, with each preset range corresponding to a degree level.

[0075] Specifically, the first detection device 20 can divide the engagement depth into multiple preset ranges based on the engagement depth corresponding to different damage conditions of the locking rod 201. The number of ranges is not limited; for example, it can be divided into three, four, or five ranges, and each range corresponds to a severity level. For example, one level corresponds to no damage, one level to minor damage, one level to moderate damage, and one level to severe damage. Therefore, the damage information of the first detection device 20 also includes the severity level, with different levels corresponding to different damage conditions. During detection, the severity level of the locking rod 201 of the charging gun 200 is determined based on the engagement depth detected by the first detection device 20 and the multiple preset ranges. This facilitates subsequent targeted implementation of corresponding enforcement measures based on the severity level, thereby improving the safety of the charging gun 200.

[0076] Please see Figure 2 and Figure 10 In some embodiments, the damage information includes a severity level. Step 0122: Based on the engagement depth detected by the first detection device 20 and multiple preset ranges, determine the severity level of the locking lever 201 of the charging gun 200, including:

[0077] Step 01221: If the engagement depth is within the first preset range, determine the degree of damage as Level 1 damage. Level 1 damage indicates that the locking rod 201 is undamaged or slightly damaged.

[0078] Step 01222: If the engagement depth is within the second preset range, determine the degree of damage as Level 2 damage. Level 2 damage indicates moderate damage to the locking rod 201.

[0079] Step 01223: If the engagement depth is within the third preset range, the degree of damage is determined to be level three, which indicates that the locking rod 201 is severely damaged.

[0080] Specifically, the first detection device 20 can divide the engagement depth into multiple ranges based on the different engagement depths corresponding to different damage conditions of the locking rod 201. The number of ranges is not limited; for example, it can be divided into three, four, or five ranges, and each range corresponds to a severity level. Therefore, the damage information of the first detection device 20 also includes severity levels, with different levels corresponding to different damage conditions.

[0081] For example, the bonding depth can be divided into three ranges: a first preset range, a second preset range, and a third preset range. The minimum value of the first preset range is greater than the maximum value of the second preset range, and the minimum value of the second preset range is greater than the maximum value of the third preset range. In other words, among the three ranges, the bonding depth corresponding to the first preset range is the greatest, followed by the second preset range, and the bonding depth corresponding to the third preset range is the smallest.

[0082] When the locking rod 201 is undamaged or only slightly damaged, it can reliably lock with the connecting part 30. During charging, without damaging the charging gun 200 or using emergency unlocking, a person cannot pull the charging gun 200 out of the vehicle. In this case, the charging gun 200 is highly safe to use and can be used normally. A first preset range can be set for the engagement depth based on whether the locking rod 201 is undamaged or only slightly damaged, and the corresponding severity level can be set as Level 1 damage. Level 1 damage indicates that the locking rod 201 is undamaged or only slightly damaged.

[0083] In some cases, the locking lever 201 can engage with the vehicle's connection part 30 during charging, but the charging gun 200 can be pulled out by forceful shaking or pulling. In this case, the deformation and damage of the locking lever 201 can be considered as moderate damage. Based on the moderate damage of the locking lever 201, a second preset range can be set for the engagement depth, and the severity level corresponding to the second preset range can be set as level two damage. Level two damage represents moderate damage to the locking lever 201.

[0084] In some cases, during charging, the locking lever 201 and the vehicle's engagement portion 30 may fail to form an effective lock, or the engagement surface between the locking lever 201 and the vehicle's engagement portion 30 may be too small or not engaged at all. This could lead to situations where the locking lever 201 is plugged in while still powered on. In such cases, the deformation and damage to the locking lever 201 can be considered severe damage. Based on the severe damage to the locking lever 201, a third preset range can be set for the engagement depth, and the corresponding severity level can be set as Level 3 damage. Level 3 damage indicates severe damage to the locking lever 201.

[0085] For example, please combine Figure 11 , Figure 11 In this context, L0-L2 represent the engagement depth, with L0 > L1 > L2. A first preset range, a second preset range, and a third preset range can be set based on the engagement depth under different damage conditions. For example, the first preset range is L0 ≥ X > L1, the second preset range is L1 ≥ X > L2, and the third preset range is L2 ≥ X, where X is the engagement depth. After the locking rod end 2012 extends into the engagement portion 30, it can be determined which preset range the engagement depth falls within, thereby determining the current degree of damage to the locking rod 201. It should be noted that... Figure 11The shown ratios are not actual proportions of the bonding depth; they are merely examples of a feasible embodiment for a more detailed explanation of the bonding depth.

[0086] Therefore, if the engagement depth output by the first detection device 20 is within the first preset range, the damage information can be confirmed as no damage or minor damage, and the severity level is Level 1 damage. If the engagement depth is within the second preset range, the damage information is determined to be damage to the locking rod 201, and the severity level is Level 2 damage. If the engagement depth is within the third preset range, the damage information is determined to be damage to the locking rod 201, and the severity level is Level 3 damage.

[0087] Of course, the preset range can also be set to four, and the severity levels can also be divided into four categories: no damage, level one damage, level two damage, and level three damage. Simply set the corresponding preset range based on the engagement depth corresponding to each severity level, and then determine the current damage status of the locking rod 201 based on the preset range and the engagement depth detected by the first detection device 20.

[0088] In this way, the degree of damage to the locking rod 201 can be determined based on multiple preset ranges and the engagement depth detected by the first detection device 20, so as to facilitate the implementation of corresponding enforcement measures according to the degree level, thereby improving the safety of the charging gun 200.

[0089] Please see Figure 2 and Figure 12 In some implementations, the damage information includes a severity level, and the charging gun detection method further includes:

[0090] Step 014: If the severity level is higher than the preset severity level, issue an alarm and restrict the use of the charging gun.

[0091] Specifically, in some embodiments, the damage levels correspond to different conditions. The preset damage level is the highest level at which the charging gun 200 is considered to have high safety. For example, the damage levels include four levels: Level 1 damage indicates no damage to the locking rod 201, Level 2 damage indicates slight damage to the locking rod 201, Level 3 damage indicates moderate damage to the locking rod 201, and Level 4 damage indicates severe damage to the locking rod 201. Assuming the locking rod 201 is undamaged or slightly damaged, the charging gun 200 is considered to have high safety; therefore, the preset damage level could be Level 2. If the damage level is higher than the preset level, the charging gun 200 is considered to have low safety, in which case an alarm is issued and its use is restricted. If the damage level is less than or equal to the preset level, the charging gun 200 is considered to have high safety, in which case no alarm is issued and its use is not restricted.

[0092] In some embodiments, the electrical equipment 100 is a charging pile. If the severity level exceeds a preset level, an alarm can be issued to the user and / or maintenance personnel. The specific recipients of the alarm are determined based on the usage of the charging pile. When the charging pile is connected to a vehicle, an alarm can be issued to the user, or simultaneously to both maintenance personnel and the user. When the charging pile is not connected to a vehicle, an alarm can be issued only to the maintenance personnel. In some embodiments, the electrical equipment 100 is a vehicle. If the severity level exceeds a preset level, an alarm can be issued only to the user.

[0093] Specifically, the usage restrictions on the charging gun 200 can be lifted by the user and / or maintenance personnel. When the electrical equipment 100 is a charging pile, if the damage level is greater than a preset level (e.g., Level 2 damage indicates minor damage to the locking rod 201, Level 3 damage indicates moderate damage, and Level 4 damage indicates severe damage), and the preset damage level is Level 2, but the currently detected damage level is greater than Level 2 (e.g., Level 3 or Level 4), then regardless of whether the usage restrictions on the charging gun 200 are lifted, an alarm must be issued to the maintenance personnel to notify them to repair or replace the charging gun 200. When the electrical equipment 100 is a vehicle, if the damage level is greater than the preset level, no alarm needs to be issued to the maintenance personnel.

[0094] In this way, it can be determined whether an alarm needs to be issued and whether the use of the charging gun 200 needs to be restricted according to the severity level, thereby improving the safety of the use of the charging gun 200.

[0095] Please see Figure 2 and Figure 13 In some implementations, the damage information includes a severity level, and the charging gun detection method further includes:

[0096] Step 015: In the case of Level 1 damage, the use of the charging gun 200 is not restricted. Level 1 damage indicates that the locking rod 201 is undamaged or slightly damaged; and / or

[0097] Step 014: When the severity level is greater than the preset severity level, the following steps are taken:

[0098] Step 0141: In the event of damage level 2 or 3, issue an alarm and restrict the use of the charging gun 200. Level 2 damage indicates moderate damage to the locking rod 201, and level 3 damage indicates severe damage to the locking rod 201.

[0099] Specifically, Level 1 damage indicates that the locking rod 201 is undamaged or slightly damaged. In the case of Level 1 damage, the locking rod 201 can reliably lock with the connecting part 30, and the charging gun 200 has a high level of safety. At this time, the use of the charging gun 200 can be unrestricted.

[0100] Level 2 damage indicates moderate damage to the locking lever 201. In the case of Level 2 damage, the locking lever 201 can engage with the vehicle's connection part 30 during charging, but the charging gun 200 can be pulled out by forceful shaking or pulling. At this time, the safety of using the charging gun 200 is low, so an alarm can be issued and the use of the charging gun 200 can be restricted.

[0101] Level 3 damage indicates severe damage to the locking lever 201. In the case of Level 3 damage, the locking lever 201 cannot effectively lock with the vehicle's connection 30 during charging. The engagement surface between the locking lever 201 and the vehicle's connection 30 is small or not engaged, which may result in live plugging and unplugging during charging. In this case, the safety of using the charging gun 200 is very low, so an alarm can be issued and the use of the charging gun 200 can be restricted.

[0102] Therefore, if the degree of damage indicates that the charging gun 200 has low or very low safety, an alarm will be issued and its use will be restricted. If the degree of damage indicates that the charging gun 200 has high safety, no alarm will be issued or its use will be restricted. In this way, whether to issue an alarm and whether to restrict the use of the charging gun 200 can be determined based on the degree of damage, thereby ensuring user safety.

[0103] Please see Figure 2 and Figure 14 In some implementations, the damage information includes a severity level. Step 0141: In the event of a level 2 or level 3 damage, an alarm is issued and the use of the charging gun 200 is restricted, including:

[0104] Step 01411: In the event of a level 2 damage, limit the charging current of the charging gun 200 to below a preset current threshold and issue a charging limit warning. This warning is used to inform the user and / or maintenance personnel that charging of the charging gun 200 is currently restricted; and / or

[0105] Step 01412: If the damage level is Level 2 and the user and / or maintenance personnel have lifted the charging current limit of the charging gun 200, issue an operation prohibition alarm. The operation prohibition alarm is used to remind the user and / or maintenance personnel that the charging gun 200 must not be unplugged during the charging process and to ensure proper on-site control.

[0106] Specifically, in the case of level two damage, the locking lever 201 can be considered moderately damaged. During charging, the locking lever 201 can engage with the vehicle's connection point 30, but the charging gun 200 can be pulled out by forceful shaking or pulling. Therefore, in the case of level two damage, the charging gun 200 can still charge, but the charging current of the charging gun 200 needs to be limited to below a preset current threshold. The preset current threshold is the safe charging current at which the vehicle can reduce the power supply circuit current to below a safe current threshold and the voltage to below a safe voltage threshold within a short period after the charging gun 200 is pulled out. The safe current threshold and safe voltage threshold are the current and voltage values ​​of the vehicle that will not affect personal safety and property safety after the charging gun 200 is pulled out; for example, the safe current threshold is 5A and the safe voltage threshold is 60V DC. During vehicle charging, the charging vehicle and the charging pile can communicate and send messages to each other. When either the vehicle or the charging station issues a stop charging command, the charging station will first release the current, reducing it below the safe current threshold through the charging module or other means. Then, it will disconnect the contactor connecting the charging station to the vehicle, releasing the voltage below the safe voltage threshold. Simultaneously, a charging restriction warning can be sent to the user and / or maintenance personnel. If the electrical equipment 100 is a charging station, both the user and maintenance personnel can receive the charging restriction warning. If the electrical equipment 100 is a vehicle, only the user can receive the charging restriction warning. The stop charging warning could be something like "Partial damage to locking lever 201, therefore limiting charging current," to inform the user that charging from the charging gun 200 is currently restricted.

[0107] In some embodiments, to improve the user experience, either the user or maintenance personnel can manually remove the charging current limit. When the user or maintenance personnel remove the charging current limit, the charging gun 200 can charge normally. Simultaneously, an operation prohibition alarm can be issued to the user and / or maintenance personnel. If the electrical equipment 100 is a charging pile, both the user and maintenance personnel can receive the operation prohibition alarm. If the electrical equipment 100 is a vehicle, only the user can receive the operation prohibition alarm. This operation prohibition alarm serves as a reminder to the user and / or maintenance personnel that the charging gun 200 must not be unplugged during charging, and to ensure proper on-site management. For example, the user should not operate the charging gun 200 until the vehicle issues a "stop charging, allow unplugging" prompt. During charging, the user's gaze should not leave the charging port, and they should prevent others from touching or unplugging the charging gun 200, thus controlling the charging process. Another example is reminding maintenance personnel to strengthen the management of the charging process.

[0108] Specifically, if the electrical equipment 100 is a charging pile and the damage level is Level 2, the charging pile still needs to send an inspection reminder to the maintenance personnel regardless of whether the charging gun 200 is charging, to remind them to repair or replace the charging gun 200, thereby ensuring the safe use of the charging gun 200. However, if the electrical equipment 100 is a vehicle, only a charging limit reminder needs to be sent to the user, allowing the user to remove the charging current limit of the charging gun 200, and an inspection reminder does not need to be sent to the maintenance personnel.

[0109] Thus, at level two, the charging current can be reduced to decrease the risk of the charging gun 200 being unplugged during charging, thereby ensuring the safe use of the charging gun 200. Simultaneously, users or maintenance personnel can remove the charging current limit. When this limit is removed, an operation prohibition alarm can be issued to inform users and / or maintenance personnel that caution should be exercised when using the charging gun 200 during charging, thereby improving the safety of the charging gun 200.

[0110] Please see Figure 2 and Figure 14 In some embodiments, the damage information includes a severity level. Step 0141: In the event of a level 2 or level 3 damage, an alarm is issued and the use of the charging gun 200 is restricted, including:

[0111] Step 01413: In the event of a level three damage, charging gun 200 shall be prohibited from charging, and a charging prohibition prompt shall be issued. This prompt is to inform the user and / or maintenance personnel that charging gun 200 is prohibited from charging at this time; and / or

[0112] Step 01414: When the user and / or maintenance personnel remove the charging restriction of the charging gun 200, an operation prohibition alarm is issued. The operation prohibition alarm is used to remind the user and / or maintenance personnel that the charging gun 200 must not be unplugged during the charging process, and to ensure proper on-site control.

[0113] Specifically, in the case of a level three damage, the locking lever 201 is considered severely damaged, and the charging gun 200 is considered to have low safety. Therefore, charging gun 200 should be prohibited from charging, and a prohibition on charging should be issued to maintenance personnel and / or users. If electrical equipment 100 is a charging pile, a prohibition on charging should be issued to both users and maintenance personnel. If electrical equipment 100 is a vehicle, a prohibition on charging should only be issued to the user. The charging stop reminder could be "The locking lever 201 is severely damaged, therefore charging is stopped," to inform users or maintenance personnel that charging gun 200 is prohibited at this time, thus reminding users or maintenance personnel that charging in this state carries a significant risk and the charging process should not be initiated.

[0114] In some embodiments, to improve the user experience, users or maintenance personnel can manually deactivate the charging stop, i.e., manually restore the charging function of the charging gun 200. With the charging function of the charging gun 200 restored, it can charge normally. Simultaneously, an operation prohibition alarm can be issued to maintenance personnel and / or users. If the electrical equipment 100 is a charging pile, both users and maintenance personnel can be alerted simultaneously. If the electrical equipment 100 is a vehicle, only the user can be alerted. This operation prohibition alarm serves as a reminder to users or maintenance personnel that the charging gun 200 must not be unplugged during charging, and to ensure proper on-site management. For example, users should be reminded not to operate the charging gun 200 until the vehicle issues a stop charging warning, and that their eyes should not leave the charging port during charging. Users should also prevent others from touching or unplugging the charging gun 200, thus controlling the charging process. Another example is reminding maintenance personnel to strengthen the management of the charging process.

[0115] Specifically, if electrical equipment 100 is a charging station and the damage level is level three, the charging station still needs to send an inspection reminder to maintenance personnel regardless of whether the charging gun 200 is charging, to remind them to repair or replace the charging gun 200, thereby ensuring the safe use of the charging gun 200. However, if electrical equipment 100 is a vehicle, only a "charging prohibited" reminder needs to be sent to the user, allowing the user to lift the charging restriction on the charging gun 200, and an inspection reminder does not need to be sent to maintenance personnel.

[0116] Thus, under level three conditions, charging gun 200 can be disabled to ensure its safe use. Simultaneously, users or maintenance personnel can restore the charging function of charging gun 200. Upon restoration, an operation prohibition alarm will be issued to inform users or maintenance personnel to use charging gun 200 with caution during charging, thereby improving the safety of charging gun 200.

[0117] Please see Figure 3 , Figure 6 and Figure 15 In some embodiments, step 011: detecting the engagement depth of the locking rod 201 of the charging gun 200 and the joint 30 of the electrical equipment 100 by the first detection device 20 of the electrical equipment 100 includes:

[0118] Step 0111: When the second detection device 60 detects that the charging gun body 202 is in place, the electrical equipment 100 is provided with a receiving groove 40 for accommodating the charging gun body 202 of the charging gun 200 and a second detection device 60, based on the engagement depth of the locking rod 201 and the joint 30 detected by the first detection device 20. The second detection device 60 is used to detect whether the charging gun body 202 is in place.

[0119] Specifically, the electrical equipment 100 may also be equipped with a second detection device 60 for detecting whether the charging gun body 202 is in position. "In position" refers to the charging gun body 202 being placed in the receiving slot 40. In one embodiment, the second detection device 60 is located on the mating surface where the charging gun body 202 contacts the receiving slot 40. For example, if the electrical equipment 100 is a charging pile, when the user returns the charging gun 202 after use or when the charging pile is in standby mode, the charging pile can use the second detection device 60 to determine whether the charging gun 200 is in position, i.e., whether the charging gun 200 is placed back into the receiving slot 40. Alternatively, if the electrical equipment 100 is a vehicle, the vehicle can use the second detection device 60 to determine whether the charging gun 200 is inserted into the receiving slot 40, so that the charging process can be started after the charging gun body 202 is inserted into the receiving slot 40.

[0120] After the charging gun body 202 is engaged with the receiving groove 40, the charging gun 200 can be considered to be in position. The second detection device 60 can be used to detect the engagement of the charging gun body 202 and the receiving groove 40. For example, the second detection device 60 is a micro switch. After the charging gun body 202 is inserted into the receiving groove 40, the charging gun body 202 will abut against and squeeze the micro switch, causing the top surface of the micro switch to start moving. If the stroke of the micro switch is within a preset stroke threshold, the charging gun 200 can be considered to be in position.

[0121] Therefore, only when the second detection device 60 detects that the charging gun body 202 is in place is it considered that the locking rod 201 and the connecting part 30 have completed their engagement. Then, the damage information of the locking rod 201 is determined based on the engagement depth detected by the first detection device 20. This avoids the first detection device 20 detecting the damage of the locking rod 201 when the charging gun 200 is not placed on the electrical equipment 100. It ensures that the first detection device 20 will only detect the damage of the locking rod 201 when it can detect 201, thereby reducing unnecessary detection by the first detection device 20 and saving the computational load and unnecessary energy consumption of the first detection device 20 and even the electrical equipment 100.

[0122] Of course, the second detection device 60 may not be installed on the vehicle. The vehicle determines whether the charging gun body 202 is inserted into the receiving slot 40 by detecting the voltage change at the CC signal detection point. If the charging gun body 202 is confirmed to be inserted into the receiving slot 40, the first detection device 20 is then used to detect damage to the locking rod 201. In this way, it is also possible to avoid detecting the damage to the locking rod 201 when the charging gun 200 is not placed on the electrical equipment 100, thereby saving computational load and unnecessary energy consumption.

[0123] Please see Figure 3 , Figure 6 and Figure 16 In some embodiments, step 011: detecting the engagement depth of the locking rod 201 of the charging gun 200 and the joint 30 of the electrical equipment 100 by the first detection device 20 of the electrical equipment 100 includes:

[0124] Step 0112: When the first detection device 20 confirms that the charging gun body 202 is in place, the electrical equipment 100 is provided with a receiving groove 40 for accommodating the charging gun body 202 of the charging gun 200, according to the first detection device 20 detecting the engagement depth of the locking rod 201 and the joint 30. The first detection device 20 is used to detect whether the charging gun body 202 is in place and the engagement depth of the locking rod 201 and the joint 30.

[0125] Specifically, the electrical equipment 100, such as a charging pile, can reuse the first detection device 20, that is, the first detection device 20 can be used to simultaneously detect whether the charging gun body 202 is in place and the engagement depth of the locking rod 201 and the connecting part 30. It can be understood that when the locking rod 201 is engaged with the connecting part 30, the charging gun 200 also extends into the receiving groove 40. Therefore, when the first detection device 20 detects that the locking rod 201 is engaged with the connecting part 30, the charging gun body 202 can be considered to be in place. In one embodiment, the charging gun body 202 can also be considered to be in place after the first detection device 20 detects that the locking rod 201 is engaged with the connecting part 30 for a certain period of time, to prevent the electrical equipment 100 from performing lock rod 201 damage detection before the locking rod 201 is fully engaged with the connecting part 30, which would lead to a deviation between the damage result and the actual situation. In another embodiment, after the first detection device 20 detects that the locking rod 201 is engaged with the connecting part 30, lock rod 201 damage detection can be performed at multiple consecutive moments. If the damage information at the last one or more moments indicates that the locking lever 201 is not damaged, then the locking lever 201 can be considered undamaged. If the damage information at all moments indicates that the locking lever 201 is damaged, then the locking lever 201 can be considered damaged.

[0126] Once the first detection device 20 confirms that the charging gun body 202 is in place, it then determines whether the locking rod 201 of the charging gun 200 is damaged based on the engagement depth detected by the first detection device 20. In this way, damage detection of the locking rod 201 can be achieved by reducing one detection device. This reduces the manufacturing cost of the electrical equipment 100 and ensures that damage detection of the locking rod 201 is only performed using the detection information from the first detection device 20 when the locking rod 201 is engaged with the connecting part 30, avoiding excessively frequent detection of damage to the locking rod 201, thus saving computational load and unnecessary energy consumption.

[0127] Of course, the vehicle determines whether the charging gun body 202 is inserted into the receiving slot 40 by detecting the voltage change at the CC signal detection point. Therefore, the first detection device 20 on the vehicle can also only detect the engagement depth between the locking rod 201 and the joint 30.

[0128] Please see Figure 2 , Figure 6 and Figure 17 In some embodiments, the electrical equipment 100 includes a charging pile, and the charging gun detection method further includes:

[0129] Step 016: When the charging gun 200 has finished charging and the idle time of the charging gun 200 is less than the first preset time, if the charging gun 200 is inserted into the vehicle, the charging gun 200 is controlled to run based on the damage information of the charging gun 200 during the last charging. The idle time is the time after charging is completed, the charging pile does not detect the charging gun body 202 returning to its position and the charging gun 200 is not inserted into the vehicle.

[0130] Specifically, after charging is complete, users may forget to return the charging gun 200 to the charging station and instead leave it elsewhere. Leaving the charging gun 200 outdoors may expose it to damage from external impurities, such as dust or stones. If the charging gun 200 is left outdoors for an extended period, the locking lever 201 is more likely to be damaged, thus affecting the performance of the charging gun 200.

[0131] When the charging station detects the charging gun body 202, it can be considered that the charging gun body 202 has returned to its original position, which also means that the charging gun 200 has returned to its original position. If the charging station does not detect the charging gun body 202 returning to its original position for an extended period of time, or if the charging gun 200 is not placed in the next charging vehicle or returned to the vehicle it was previously charging, it can be considered that the charging gun 200 has been idle for an extended period of time. In this case, the probability of the locking lever 201 being damaged is relatively high. Therefore, a first preset time period can be set. The first preset time period can be determined based on the longest time when the probability of the charging gun 200 being damaged by external forces is low when it is placed in an area outside the charging station and the vehicle.

[0132] After charging is completed, i.e. after the charging gun 200 has no power output, the electrical equipment 100 can start timing to determine the idle time of the charging gun 200. The idle time is the time during which the charging pile does not detect the charging gun body 202 returning to its position after charging is completed and the charging gun 200 is not inserted into a vehicle. In other words, it is the time during which the charging gun 200 does not return to its position after charging is completed and the charging gun is not inserted into the vehicle that was previously charged or another vehicle that was charged and charging has started.

[0133] If the charging gun 200 has finished charging and its idle time is less than a first preset time, and the charging gun 200 is then inserted into the vehicle, it can be assumed that the probability of the locking lever 201 being damaged during the idle time is low. In this case, the damage to the locking lever 201 is likely consistent with the damage during the previous charging of the charging gun 200. Therefore, the operation of the charging gun 200 can be controlled based on the damage information from the previous charging. For example, if the damage information from the previous charging was level one, then the charging gun 200 can be controlled to charge according to the level one charging strategy.

[0134] Once the charging gun 200 is inserted into the vehicle, if the vehicle is also equipped with a first detection device 20, then the first detection device 20 can be used to detect the current damage status of the locking lever 201. After the vehicle's first detection device 20 completes its detection, the operation of the charging gun 200 can be controlled based on the damage information obtained from the vehicle's first detection device 20.

[0135] In this way, when the idle time is short, the operation of the charging gun 200 can be controlled based on the damage information of the charging gun 200 during the last charging, so as to ensure the normal operation of the charging pile.

[0136] Please see Figure 2 , Figure 6 and Figure 18 In some embodiments, the electrical equipment 100 includes a charging pile, and the charging gun detection method further includes:

[0137] Step 017: If the charging gun 200 has been fully charged and the idle time of the charging gun 200 is not less than the first preset time, charging is prohibited and a preset reminder is issued. The preset reminder is used to remind the relevant personnel of the charging pile to check and / or return the charging gun 200 to its original position. The relevant personnel include users and / or maintenance personnel.

[0138] Specifically, when the charging pile is equipped with a first detection device 20 and a second detection device 60, the second detection device 60 can also perform a return-to-position detection of the charging gun body 202 even if the locking rod 201 is damaged. Therefore, when the charging pile is equipped with a first detection device 20 and a second detection device 60, if the idle time of the charging gun 200 is not less than a first preset time, that is, if the idle time of the charging gun 200 is greater than or equal to the first preset time, it can be considered that the charging gun 200 has not been returned to its position for a long time, and the probability of the charging gun 200 being damaged by external factors is relatively high, and the damage to the locking rod 201 is unknown.

[0139] When the charging station only has a first detection device 20, which simultaneously detects whether the charging gun body 202 is in place and the engagement depth of the locking rod 201 and the connecting part 30, damage to the locking rod 201 may cause the charging station to fail to detect the charging gun body 202 returning to its original position for an extended period or to fail to detect that the charging gun 200 has not been inserted into the next vehicle. Therefore, when the charging station only has the first detection device 20, the first preset time can also be determined by combining the longest time when the probability of external damage to the charging gun 200 is low when it is placed in an area outside the charging station and the vehicle, and the longest time under normal circumstances when the user returns the charging gun 200 to its original position. If the idle time of the charging gun 200 is greater than or equal to the first preset time, it can be considered that the locking rod 201 is damaged or the charging gun 200 has not returned to its original position for a long time, that is, the damage to the locking rod 201 is either very serious or in an unknown state.

[0140] If the idle time exceeds a first preset time, charging can be prohibited. Therefore, if charging gun 200 has completed charging and the idle time of charging gun 200 is not less than the first preset time, it can be considered that charging gun 200 has not performed a damage detection on locking rod 201 for a long time. At this time, the damage condition of locking rod 201 cannot be accurately determined, so charging can be prohibited to ensure the safe use of charging gun 200. That is, if the damage condition of locking rod 201 is unknown, charging should not be performed to ensure the safe use of charging gun.

[0141] Simultaneously, preset reminders can be sent to relevant personnel at the charging station. These personnel include maintenance staff and / or users. The preset reminders are used to remind these personnel to check and / or return the charging gun 200 to its proper position. The charging station can also send preset reminders to maintenance staff to remind them to check or return the charging gun 200 to its proper position. Furthermore, the charging station can send preset reminders to users to remind them to return the charging gun 200 to its proper position.

[0142] In this way, the situation of the lock rod 201 being damaged or the charging gun 200 not returning to its position for a long time can be determined based on the idle time of the electrical equipment 100, so as to promptly prohibit the charging pile from charging, ensure the safe use of the charging gun, and issue a preset reminder in a timely manner so that users or maintenance personnel can promptly handle the charging gun 200 after seeing it.

[0143] Please see Figure 2 and Figure 19 In some implementations, step 017: issuing a preset reminder includes:

[0144] Step 0171: If the charging gun 200 is not plugged into the vehicle, send an inspection reminder to the maintenance personnel. The inspection reminder is used to remind the maintenance personnel to inspect the charging gun 200.

[0145] Specifically, if the idle time is greater than or equal to a first preset time and the charging gun 200 is not plugged into the vehicle, it can be considered that the charging gun 200 is not in use. At this time, a check reminder is issued to the maintenance personnel. The check reminder is used to remind the maintenance personnel to check the charging gun 200, so as to notify the maintenance personnel to check the status of the charging gun and put it back in place. At this time, the check reminder can be issued immediately when the idle time is equal to the first preset time, or the check reminder can be issued continuously when the idle time is greater than the first preset time and the charging gun 200 is not plugged into the vehicle, to ensure that the maintenance personnel can see the check reminder in a timely manner.

[0146] Thus, if the idle time is greater than or equal to the first preset time and the charging gun 200 is not inserted into the vehicle, the maintenance personnel can be notified in a timely manner to check the charging gun 200, determine whether the charging gun 200 is back in place, and determine whether the locking rod 201 is damaged if the charging gun 200 is back in place.

[0147] Please see Figure 2 and Figure 20 In some implementations, step 017: issuing a preset reminder includes:

[0148] Step 0172: When the charging gun 200 is inserted into the vehicle, a charging gun 200 return reminder is issued to remind the user to return the charging gun 200 to its original position.

[0149] Step 0173: After the charging gun 200 is returned to its original position and the damage information is obtained, restore the charging function of the charging gun 200.

[0150] Specifically, if the charging gun 200 is inserted into the vehicle after a period of inactivity exceeding a first preset time, it indicates that a user has inserted the charging gun 200 into the vehicle before maintenance personnel arrive at the charging station area and inspect the charging gun 200. In this case, a charging gun 200 return reminder can be issued to remind the user to return the charging gun 200 to its original position. After the charging gun 200 is returned to its original position, the charging station can re-enter step 012 to perform a locking lever 201 detection on the charging gun 200. After the detection is completed, damage information can be obtained. After obtaining the damage information, the charging function of the charging gun 200 can be restored, meaning the charging gun 200 can now charge. The user can then operate the charging gun 200 to charge the vehicle, and the charging station can determine the corresponding charging strategy based on the locking lever 201 detection result. In some embodiments, a charging reminder is also issued to remind the user to unplug the charging gun. After seeing the charging reminder, the user can operate the charging gun 200 to charge the vehicle.

[0151] If maintenance personnel arrive at the charging station area before the user, i.e., before the charging gun 200 is plugged into the vehicle, even if the station has been idle for more than the first preset time, the maintenance personnel can inspect and return the charging gun 200 to its original position. Then, the electrical equipment 100 can perform a locking rod 201 test on the charging gun 200. After the locking rod 201 test is completed, the charging gun 200 can be used normally.

[0152] Thus, if the charging gun 200 is idle for an extended period and the locking rod 201 has not been inspected for a long time, and the damage status of the locking rod 201 is unknown, the charging station can be stopped from charging. The charging gun 200 can only be used after the user or maintenance personnel return the charging gun 200 to its original position, inspect the locking rod 201, and the electrical equipment 100 obtains the current damage information of the locking rod 201, thereby ensuring the safe use of the charging gun 200.

[0153] Please see Figure 2 , Figure 21 and Figure 22 In some embodiments, the electrical equipment 100 includes a charging pile, and the charging gun detection method includes:

[0154] Step 018: Determine the damage information of the locking rod 201 based on the circuit status of the conductor 203. The damage information includes whether the locking rod 201 is broken. The electrical equipment 100 includes a charging gun 200. The locking rod 201 is provided with a conductor 203. The conductor 203 extends to the area corresponding to the locking rod 201 and the joint 30. When the locking rod 201 is intact, the conductor 203 forms a current loop. When the locking rod 201 is broken, the conductor 203 is disconnected and the current loop is broken.

[0155] Specifically, when the electrical equipment 100 includes a charging pile, a self-testing device can also be installed on the charging gun 200 to allow the charging gun 200 to determine whether it is damaged. A break in the locking rod 201 will affect the engagement depth between the locking rod 201 and the connecting portion 30; therefore, the damage information may also include whether the locking rod 201 is broken. The charging pile can have a conductor 203 installed inside the locking rod 201, extending to the area corresponding to the connecting portion 30. That is, the conductor 203 can be installed in the locking rod body 2011 and extend to the locking rod end 2012, for example, extending to the top of the locking rod end 2012 corresponding to the bottom of the connecting portion 30.

[0156] Conductor 203 forms a current loop when intact, and the current loop breaks when conductor 203 is broken. By adjusting the material of conductor 203, it can be ensured that conductor 203 also breaks when locking rod 201 breaks. This allows the energization of the current loop in conductor 203 to reflect whether locking rod 201 is broken, suggesting a lower bonding depth if locking rod 201 is broken. For example, please combine... Figure 22 A groove is cut inside the locking rod 201, extending to the locking hook. The conductor 203 is first fixed to the inner surface of the groove using adhesive or other methods, and then the groove is filled using injection molding or other processes. Simultaneously, the conductor 203 can be made of a material with poor toughness and easy breakage, such as graphite, so that the conductor 203 can detach along with the broken locking rod 201 if it breaks.

[0157] Therefore, a voltage can be applied to conductor 203, and the continuity of conductor 203 can be determined by detecting its electrical parameters, such as current, voltage, or resistance. When conductor 203 is open, the electrical parameters are all within the normal range. When conductor 203 is open, the voltage and current are 0, and the resistance is infinite.

[0158] The charging gun 200 can detect the continuity status of the conductor 203 in real time and determine whether the locking rod 201 is broken based on the continuity status of the conductor 203, thereby determining whether the locking rod 201 is damaged. When the locking rod 201 is intact, the conductor 203 can form a complete circuit. The charging pile can detect that the conductor 203 can form a circuit and considers the locking rod 201 to be broken, that is, the locking rod 201 is not damaged. When the locking rod 201 is broken due to external force, because the conductor 203 material is brittle, it will fall off together with the broken locking rod 201. At this time, the conductor 203 inside the locking rod 201 cannot form a current circuit, that is, the current circuit is broken. The charging pile can detect the conductor 203 is broken, and the charging pile determines that the locking rod 201 is broken, that is, the locking rod 201 is damaged. The connection depth between the locking rod 201 and the joint 30 is low, and the safety of the charging gun 200 is low. After determining whether the locking rod 201 is broken, the subsequent execution strategy can be determined according to the breakage situation. The execution strategy can refer to the execution strategies under different connection depths mentioned above. For example, if the locking lever 201 is determined to be broken, the charging process can be stopped or not started, and maintenance personnel should be notified to repair or replace the charging gun 200. If the user or maintenance personnel need to remove the charging restriction, the restriction can only be lifted after confirmation with the user or maintenance personnel and informing them to implement on-site control measures. If the locking lever 201 is determined to be intact and not broken, the charging process can be started normally.

[0159] Furthermore, an insulating component can be added around the conductor 203 for protection to prevent electrical conduction between the conductor 203 and the locking rod 201, thereby ensuring the safe use of the charging gun 200.

[0160] In this way, the conductor 203 can be used to perform a self-check for the breakage of the locking rod 201, and the breakage of the locking rod 201 can be detected in a timely manner, thereby facilitating the accurate determination of the subsequent execution strategy and improving the safety of the charging gun 200.

[0161] Please see Figures 22 to 24 In some embodiments, the electrical equipment 100 includes a charging pile, and the charging gun detection method includes:

[0162] Step 019: Based on the detection results of the third detection device 204, determine the damage information of the locking rod 201. The damage information includes whether the locking rod 201 has been deformed. The third detection device 204 is installed inside the locking rod 201 and is used to detect whether the locking rod 201 has been deformed.

[0163] Specifically, the conduction state of conductor 203 can only be used to indicate whether the locking rod 201 is broken. However, deformation of the locking rod 201 also affects the bonding depth between the locking rod 201 and the connecting part 30, so the damage information also includes whether the locking rod 201 is deformed. The electrical equipment 100 may provide a third detection device 204 inside the locking rod 201. The third detection device 204 is used to detect whether the locking rod 201 has deformed. The third detection device 204 may be located in the locking rod body 2011, the locking rod end 2012, or both. For example, the third detection device 204 may be a strain gauge, which is a sensor capable of measuring relative changes in length (strain). When the locking rod 201 deforms, the strain gauge also deforms, causing changes in certain parameters of the strain gauge, such as the shape of the strain gauge or its electrical parameters, such as current or resistance. The strain gauge can then determine the damage information based on these parameters that change with deformation.

[0164] Therefore, the charging gun 200 can acquire the detection results from the third detection device 204 in real time to determine whether the locking rod 201 has deformed, thus facilitating the determination of subsequent execution strategies based on the deformation of the locking rod 201. The execution strategies can refer to the execution strategies for different engagement depths mentioned above. For example, if the locking rod 201 is determined to be deformed, the charging process can be stopped or not started, and maintenance personnel can be notified to repair or replace the charging gun 200. If the user or maintenance personnel need to remove the charging restriction, the restriction can only be lifted after confirmation with the user or maintenance personnel and notification to ensure proper on-site control. If the locking rod 201 is determined not to be deformed, the charging process can be started normally.

[0165] It should be noted that the electrical equipment 100 may simultaneously provide the conductor 203 and the third detection device 204 in the locking rod 201, or provide the conductor 203 alone, or provide the third detection device 204 alone, depending on the specific circumstances, and no limitation is made here.

[0166] In this way, the third detection device 204 can be used to perform a self-check of the deformation of the locking rod 201, and the deformation of the locking rod 201 can be detected in a timely manner, thereby facilitating the accurate determination of the subsequent execution strategy and improving the safety of the charging gun 200.

[0167] Please see Figure 2 and Figure 4In some embodiments, the electrical device 100 includes a receiving slot 40 for housing the charging gun body 202 of the charging gun 200. When the electrical device 100 is a vehicle, it includes a battery, and the receiving slot 40 includes a first receiving slot 41. When the charging gun body 202 is located in the first receiving slot 41, the power supply port of the charging gun body 202 can be connected to the battery, allowing the charging gun body 202 to charge the battery. At this time, the first detection device 20 can detect the engagement depth between the locking rod 201 and the connecting portion 30, thereby enabling the detection of the locking rod 201 when the vehicle is connected to the charging gun 200, facilitating timely detection of any damage to the locking rod 201.

[0168] Please see Figure 2 and Figure 6 In some embodiments, the electrical device 100 includes a receiving slot 40 for the charging gun body 202 that houses the charging gun 200. When the electrical device 100 is a charging pile, it includes a pile body, and the receiving slot 40 includes a second receiving slot 42. A power supply module is located inside the pile body. The connecting portion 30 and the second receiving slot 42 are both located within the pile body. The charging gun 200 is connected to the pile body to connect with the power supply module.

[0169] Specifically, the charging pile body is typically made of steel or aluminum alloy, offering high durability and stability. The pile body design includes panel indicator lights, panel buttons, a charging interface, and ventilation holes, and is fixed to the mounting base using anchor bolts. The power supply module is a component capable of supplying power externally. The charging gun 200 connects to the pile body to connect with the power supply module, allowing the charging gun body 202 to obtain electrical energy from the power supply module and supply it to other electrical devices for charging. The connecting part 30 and the second receiving slot 42 can be part of the pile body or a separate component, but are installed within the pile body.

[0170] Meanwhile, after charging is completed, the charging gun body 202 can be put back into the second receiving slot 42. At this time, the locking rod 201 will also be put back into the joint 30. The first detection device 20 can detect the locking rod 201, so that the detection of the locking rod 201 can be completed when the charging gun 200 is returned to its position, so as to detect the damage of the locking rod 201 in time.

[0171] Please see Figure 2 and Figure 6 There are various types of first detection devices 20. It is only necessary to ensure that the detection information of the first detection device 20 is different under different damage conditions.

[0172] Please see Figure 2 and Figure 6In some embodiments, the first detection device 20 includes a limit switch, such as a micro switch, which is a component capable of providing feedback on different strokes of switch movement. The first and second ends of the limit switch are opposite to each other. The first end of the limit switch is fixedly mounted to the bottom of the connecting portion 30, and the second end of the limit switch faces the opening of the connecting portion 30. A spring is provided inside the limit switch, allowing the second end of the limit switch to move along the depth direction of the connecting portion 30, i.e., moving up and down along the depth direction of the connecting portion 30. When the limit switch is not compressed, the second end of the limit switch is in its initial position, and the distance between the first and second ends of the limit switch is the initial distance. When the charging gun body 202 is fully inserted into the receiving groove 40, and the locking rod 201 extends into the connecting portion 30, the locking rod 201 abuts against and pushes the second end of the limit switch toward the bottom of the connecting portion 30, thereby changing the distance between the first and second ends of the limit switch.

[0173] It is understandable that when the locking lever 201 is damaged, the distance that the locking lever 201 can push the second end of the limit switch to move will be less than the distance that the locking lever 201 can push the second end of the limit switch to move when it is not damaged. Furthermore, the distance that the locking lever 201 can push the second end of the limit switch to move will vary depending on the extent of damage to the locking lever 201. After the movement distance of the second end of the limit switch changes, the distance between the first and second ends of the limit switch (i.e., the travel of the limit switch) will also change. In other words, the distance between the first and second ends of the limit switch will be different depending on the extent of damage to the locking lever 201. Therefore, the engagement depth is negatively correlated with the distance between the first and second ends of the limit switch. The engagement depth can be determined based on the distance between the first and second ends of the limit switch; the larger the distance between the first and second ends of the limit switch, the smaller the engagement depth, indicating a higher degree of damage.

[0174] The distance between the first and second ends of the limit switch can be preset for different engagement depths, i.e., when the locking rod 201 is intact and when the locking rod 201 is damaged in different ways, and a corresponding mapping relationship can be established. After obtaining the distance between the first and second ends of the limit switch at the current moment, the engagement depth can be determined according to the mapping relationship and the distance at the current moment.

[0175] Please see Figure 2 and Figure 6 In some embodiments, the first detection device 20 includes an optical sensor, the basic components of which include a light source, a photodetector, and a signal processing circuit. The light source emits light of a specific wavelength, which shines on the target object or environment. The photodetector receives the reflected or transmitted light and converts it into an electrical signal. Finally, the signal processing circuit further processes the electrical signal to obtain the desired information.

[0176] There are various installation locations, quantities, and types of optical sensors, which can be determined based on the actual situation.

[0177] For example, an optical sensor is installed at the bottom of the connecting part 30. This optical sensor is capable of measuring distance and is used to detect the distance between the end of the locking rod 201 facing the bottom of the connecting part 30 and the bottom of the connecting part 30. Depending on the degree of damage to the locking rod 201, when the charging gun body 202 is fully inserted into the receiving groove 40 and the locking rod 201 is inserted into the connecting part 30, the distance between the end of the locking rod 201 facing the bottom of the connecting part 30 and the bottom of the connecting part 30 will vary. Therefore, the connecting depth can be determined based on the distance between the end of the locking rod 201 facing the bottom of the connecting part 30 and the bottom of the connecting part 30; the greater the distance, the lower the connecting depth. The distance between the end of the locking rod 201 facing the bottom of the connecting part 30 and the bottom of the connecting part 30 can be preset for different connecting depths, i.e., when the locking rod 201 is intact and when the locking rod 201 suffers different degrees of damage, and a corresponding mapping relationship can be established. After obtaining the distance between the end of the locking lever 201 facing the bottom of the joint 30 at the current moment and the bottom of the joint 30, the joint depth can be determined based on the mapping relationship and the distance at the current moment.

[0178] For example, the first detection device 20 includes multiple optical sensors for detecting the position of an object. When an object blocks light, the light signal received by the optical sensors weakens, allowing the optical sensors to determine that the object is in place. The multiple optical sensors are installed in different areas of the sidewall of the joint 30. The installation positions of the multiple optical sensors can be determined based on the area of ​​the sidewall of the joint 30 corresponding to the locking rod 201 after the locking rod 201 is inserted into the joint 30, assuming the locking rod 201 is intact.

[0179] Multiple optical sensors are used to detect the position of the locking lever 201 within the joint 30. The distance between the end of the locking lever 201 facing the bottom of the joint 30 and the bottom of the joint 30 differs depending on whether the locking lever 201 is intact or damaged under various conditions, resulting in different positions of the locking lever 201 within the joint 30. If a particular optical sensor cannot detect the locking lever 201, it indicates that the locking lever 201 is located outside the detection range of that optical sensor within the joint 30. Therefore, the position of the locking lever 201 within the joint 30 can be determined based on the detection results of multiple optical sensors and their corresponding detection ranges, thereby determining whether the locking lever 201 is damaged and the extent of the damage. Consequently, the engagement depth is determined based on the position of the locking lever 201 within the joint 30 detected by the multiple optical sensors. The positions of the locking rod 201 at the joint 30 can be preset for different engagement depths, i.e., when the locking rod 201 is intact and when the locking rod 201 is damaged under different conditions, and a corresponding mapping relationship can be established. After obtaining the current position of the locking rod 201 at the joint 30, the engagement depth can be determined based on the mapping relationship and the current position.

[0180] For example, an optical sensor is installed at the bottom of the joint 30. When the locking rod 201 and the joint 30 are engaged, the locking rod 201 abuts against and squeezes the optical sensor. The optical sensor can reflect different wavelengths when it senses different forces. The engagement depth is determined according to the wavelength reflected by the optical sensor. For example, the optical sensor is a fiber optic grating (FBG) sensor.

[0181] When the locking lever 201 is intact and when it suffers different types of damage, the force exerted by the locking lever 201 on the optical sensor varies, resulting in different wavelengths reflected by the light sensor. Therefore, the bonding depth is determined based on the wavelength reflected by the optical sensor. The wavelengths reflected by the optical sensor under different bonding depths (i.e., when the locking lever 201 is intact and under different types of damage) can be preset, and a corresponding mapping relationship can be established. After obtaining the wavelength reflected by the optical sensor at the current moment, the bonding depth can be determined based on the mapping relationship and the wavelength at the current moment.

[0182] Thus, the first detection device 20 can determine whether the locking rod 201 is intact by the change in the optical path.

[0183] Please see Figure 2 and Figure 6In some embodiments, the first detection device 20 further includes a force sensor, which is a device or apparatus capable of sensing pressure signals and converting them into usable output detection parameters according to a certain rule. The force sensor is installed at the bottom of the coupling portion 30. When the locking rod 201 and the coupling portion 30 are engaged, the locking rod 201 abuts against and squeezes the force sensor. The force sensor detects different parameters depending on the force it senses; these detection parameters can be understood as the feedback physical quantity of the force sensor. The force exerted by the locking rod 201 on the force sensor differs depending on whether the locking rod 201 is intact or damaged under different conditions, resulting in different detection parameters. Therefore, the engagement depth is determined based on the detection parameters. The detection parameters for different engagement depths (i.e., when the locking rod 201 is intact and when it is damaged under different conditions) can be preset, and a corresponding mapping relationship can be established. After acquiring the detection parameters at the current moment, the engagement depth can be determined based on the mapping relationship and the detection parameters at the current moment. In this way, the condition of the locking lever 201 can be determined by detecting changes in the detection parameters.

[0184] In some embodiments, the mechanical sensor includes an elastic sensor or a pressure sensor.

[0185] The pressure sensor can sense whether the locking rod 201 is intact and insert it into the joint 30 by sensing force and generating strain.

[0186] The elastic sensor contains an elastic element. When the elastic element is subjected to force and deforms, the detection parameters of the elastic sensor will change, such as changes in the current, voltage or resistance of the elastic sensor.

[0187] Alternatively, the first detection device 20 may use other strain sensors to detect whether the locking bar 201 is intact by the change in other physical quantities caused by the change in other strains, without limitation.

[0188] In some embodiments, the first detection device 20 further includes a detection circuit mounted on the connecting portion 30. The detection circuit includes a detection resistor. When the locking rod 201 and the connecting portion 30 are engaged, the locking rod 201 abuts against and presses against the detection resistor. The resistance of the detection resistor varies depending on the applied force; for example, the detection resistor may be a pressure-sensitive resistor. The engagement depth is determined based on the electrical parameters of the detection circuit. These electrical parameters can be the current or voltage of the detection circuit, or the resistance that detects the voltage. The electrical parameters can be obtained from a corresponding sensor.

[0189] When the locking lever 201 is intact and when it is damaged in different ways, the force exerted by the locking lever 201 on the detection resistor varies. This results in different resistance values ​​for the detection resistor and different currents or voltages in the detection circuit, thus affecting the electrical parameters of the detection circuit. Therefore, the engagement depth is determined based on the electrical parameters of the detection circuit. The electrical parameters of the detection circuit for different engagement depths (i.e., when the locking lever 201 is intact and when it is damaged in different ways) can be preset, and a corresponding mapping relationship can be established. After obtaining the electrical parameters of the detection circuit at the current moment, the engagement depth can be determined based on the mapping relationship and the current electrical parameters of the detection circuit. In this way, the integrity of the locking lever 201 can be determined by observing changes in the electrical parameters of the detection circuit.

[0190] After the first detection device 20, based on the above embodiments, obtains the bonding depth, the subsequent execution strategy can be determined according to the bonding depth and the preset strength range. Alternatively, the detection result of the first detection device 20 can be directly used as the bonding depth for judgment. In this case, the preset range is determined according to the detection results of the first detection device 20 under different damage conditions, as well as the damage condition and execution strategy corresponding to each preset range. Subsequently, the subsequent execution strategy can be determined according to the detection results and their corresponding preset ranges. For example, when the first detection device 20 is a micro switch, the first preset range, the second preset range, and the third preset range can be determined according to the distance between the two ends of the micro switch. The first preset range corresponds to the case where the locking rod 201 is undamaged or slightly worn, the second preset range corresponds to the case where the locking rod 201 is moderately damaged, and the third preset range corresponds to the case where the locking rod 201 is severely damaged. The distance corresponding to the first preset range is the smallest, the distance corresponding to the second preset range is the second smallest, and the distance corresponding to the third preset range is the largest. Subsequently, the subsequent execution strategy can be determined directly according to these three preset ranges and the distance between the two ends of the micro switch.

[0191] The types of the second detection device 60 and the third detection device 204 can also refer to the types of the first detection device 20 mentioned above. As long as they can perform their functions, there are no restrictions here.

[0192] Please see Figure 2 , Figure 6 and Figure 25 To facilitate better implementation of the charging gun detection method of this application, this application also provides a charging gun detection device 10, which is applied to an electrical device 100. The charging gun detection device 10 may include a detection module 11 and a determination module 12. The detection module 11 is used to detect the engagement depth between the locking rod 201 of the charging gun 200 and the receiving groove 30 of the electrical device 100 according to the first detection device 20 of the electrical device 100. The determination module 12 is used to determine damage information of the locking rod 201 based on the engagement depth.

[0193] The determination module 12 is specifically used to determine whether the locking rod 2012 is damaged based on the engagement depth and the preset depth threshold.

[0194] The determination module 12 is specifically used to confirm that the locking rod 201 is damaged when the engagement depth is less than the preset depth threshold; and to determine that the locking rod 201 is not damaged when the engagement depth is greater than the preset depth threshold.

[0195] The charging gun detection device 10 also includes an alarm module 13. The alarm module 13 is used to issue an alarm and restrict the use of the charging gun 200 in the event of damage information, including damage to the locking lever 201.

[0196] The determining module 12 is specifically used to determine the degree level of the locking rod 201 of the charging gun 200 based on the bonding depth detected by the first detection device 20 and multiple preset ranges.

[0197] The determination module 12 is specifically used to determine the degree of damage as Level 1 when the engagement depth is within the first preset range, which indicates that the locking rod 201 is undamaged or slightly damaged; to determine the degree of damage as Level 2 when the engagement depth is within the second preset range, which indicates that the locking rod 201 is moderately damaged; and to determine the degree of damage as Level 3 when the engagement depth is within the third preset range, which indicates that the locking rod 201 is severely damaged.

[0198] The charging gun detection device 10 also includes a maintenance module 14. The maintenance module 14 is used to not restrict the use of the charging gun 200 in the event of a level 1 damage, where level 1 damage indicates that the locking rod 201 is undamaged or slightly damaged.

[0199] The alarm module 13 is specifically used to issue an alarm and restrict the use of the charging gun 200 when the severity level is greater than the preset severity level.

[0200] The alarm module 13 is specifically used to issue an alarm and restrict the use of the charging gun 200 when the damage level is level 2 or level 3. Level 2 damage indicates moderate damage to the locking rod 201, and level 3 damage indicates severe damage to the locking rod 201.

[0201] The alarm module 13 is specifically used to limit the charging current of the charging gun 200 to below a preset current threshold and issue a charging limit prompt when the damage level is level two. The charging limit prompt is used to inform the user that the charging of the charging gun 200 is limited at this time.

[0202] The alarm module 13 is specifically used to issue an operation prohibition alarm when the damage level is level two and the user has lifted the charging current limit of the charging gun 200. The operation prohibition alarm is used to remind the user that the charging gun 200 should not be unplugged during the charging process and to ensure on-site control.

[0203] The alarm module 13 is specifically used to prevent the charging gun 200 from charging when the damage level is level three, and to issue a charging prohibition prompt. The charging prohibition prompt is used to remind the user that the charging gun 200 is prohibited from charging at this time.
