[0003] Generally, the causes of fires in new energy vehicle charging piles include leakage, sudden fire, or excessive heat during the charging process. The power supply, as a power supply and conversion device, is more likely to generate heat than other parts of the charging pile.

DETAILED DESCRIPTION

[0031] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-10 The figure shows a charging pile control box 1 and a charging pile plug 2 connected to the charging pile control box 1. The charging pile plug 2 includes a plug shell 21, a plug guide 22 fixedly connected to the front end of the plug shell 21, and a charging handle 23 fixedly connected to the rear end of the plug shell 21. The front end of the plug shell 21 is provided with an auxiliary ring groove located outside the plug guide 22, and an anti-spontaneous combustion component 4 is connected in the auxiliary ring groove. The front end of the anti-spontaneous combustion component 4 is fixedly connected to a hollow plug adsorption ring 3 matched therewith.

[0034] The charging pile control box 1 is equipped with an anti-spontaneous combustion system, which includes an anti-spontaneous combustion processing unit. The input end of the anti-spontaneous combustion processing unit is connected to a power sensing unit, a temperature sensing unit and a plug sensing unit, and the output end of the anti-spontaneous combustion processing unit is connected to a plug control unit.

[0035] The input ends of the power sensing unit and the temperature sensing unit are both connected to the charging control system signal arranged in the charging pile control box 1, the input end of the temperature sensing unit is also connected to the temperature sensing probe signal arranged in the charging pile plug 2, and the input end of the plug-in sensing unit is connected to the abutment sensor signal embedded in the front end of the hollow plug-in adsorption ring 3. The abutment sensor here can be composed of a pressure sensor and an elastic bag. One end of the elastic bag is exposed to the outside of the front end of the hollow plug-in adsorption ring 3, and the rear end of the elastic bag is fixedly connected to the probe of the abutment sensor embedded in the hollow plug-in adsorption ring 3. When no force is applied, the exposed distance of the elastic bag is 1mm-3mm. After the charging pile plug 2 and the charging port 6 are plugged in, the abutment pressure generated by the contact between the plug-in surfaces of the charging pile plug 2 and the charging port 6 will cause the elastic bag to be squeezed and contracted, generating pressure change data for the pressure sensor, and then retracting into the hollow plug-in adsorption ring 3, and generating an abutment trigger signal. The output end of the plug-in control unit is connected to the signal of the anti-spontaneous combustion component 4 By setting the hollow plug adsorption ring 3, the anti-spontaneous combustion component 4 and the anti-spontaneous combustion system, the new energy vehicle during the charging process can be effectively monitored, and when the charging is completed or the battery is overheated or the plug position is overheated, an autonomous disconnection action is generated, and then the charging pile and the new energy vehicle can be protected by monitoring the internal factors of the charging process (internal factors include factors of spontaneous combustion caused by overcharging, continuous high battery temperature, excessive temperature of the charging pile plug 2 or poor plugging of the charging pile plug 2), so as to avoid the problem of spontaneous combustion of the charging pile during the charging process, effectively improve the safety of the charging process, and effectively achieve the effect of physical disconnection by actively disengaging the charging pile plug 2, further ensure the safety of electricity use, improve the protection effect of the charging pile, directly block the continuous influence of internal factors, ensure the battery safety of the new energy vehicle and the safety of the charging pile plug 2 of the charging pile, avoid the occurrence of problems such as leakage, and effectively promote the economic benefits of the charging pile while reducing resource loss.

[0036] Fig. 9 and Fig.10The anti-spontaneous combustion component 4 is shown to include an elastic ring 41 fixedly connected to the rear inner wall of the auxiliary ring groove, and the front end of the elastic ring 41 is fixedly connected to the hollow plug-in adsorption ring 3, a two-way control cavity is opened in the elastic ring 41, an auxiliary guide block 44 is fixedly connected to the front inner wall of the two-way control cavity, a two-way electromagnetic block 42 is fixedly connected to the rear end of the auxiliary guide block 44 and the rear inner wall of the two-way control cavity, an isolation sheet 43 is fixedly connected between the two two-way electromagnetic blocks 42, the output end of the plug-in control unit is connected to the signal of the two-way electromagnetic block 42, and the elastic ring 41 is magnetically affected by the two-way electromagnetic block 42. The deformation range caused by the action is 1-1.2 times the insertion depth of the plug shell 21. The cooperation between the bidirectional electromagnetic block 42 and the plug-in control unit can effectively control the deformation of the elastic ring 41. Furthermore, when the charging pile plug 2 is plugged into the charging port 6 to charge the new energy vehicle, the bidirectional electromagnetic block 42 drives the elastic ring 41 to deform, so as to realize the active separation of the charging pile plug 2 from the charging port 6, avoid the danger caused by continuous charging, effectively and fundamentally suppress the problem of spontaneous combustion of the charging pile, and ensure the safety of the use of the charging pile.

[0037] Figure 1 and Figure 2 It is shown that the output end of the anti-spontaneous combustion processing unit is also connected to an abnormal feedback unit, and the output end of the abnormal feedback unit is connected to the charging control system signal arranged in the charging pile control box 1. The abnormal feedback unit can effectively promote the coordination between the anti-spontaneous combustion system and the charging control system of the charging pile. When the anti-spontaneous combustion system controls the charging pile plug 2 to produce autonomous detachment, it transmits abnormal data to the charging control system, which is convenient for the charging control system to produce abnormal response actions, timely cut off the power to the charging pile plug 2, and send out alarm signals and other actions.

[0038] Figure 1 and Figure 2 It is shown that the output end of the anti-spontaneous combustion processing unit is also connected to the operation reminder unit, and the output end of the operation reminder unit is connected to the display and voice player signal arranged on the charging pile control box 1. The operation reminder unit can remind the personnel of the charging operation, and can effectively cooperate with the plug-in sensing unit to ensure the position accuracy and stability of the charging pile plug 2 plugged into the charging port 6, urge the charging operator to plug and revise the charging pile plug 2 to ensure the effective connection between the charging pile plug 2 and the charging port 6, avoid the problem of poor contact during the charging process, reduce resource loss, ensure the safety of charging, and effectively avoid the problem of high temperature generated by the new energy battery during the charging process or the high temperature generated by the charging pile plug 2.

[0039] Figure 1-10It is shown that during the use of the charging pile, the charging operator removes the charging pile plug 2 and inserts the plug shell 21 into the charging port 6 of his new energy vehicle to complete the plug-in cooperation between the charging pile plug 2 and the charging port 6. If the plug-in position of the charging pile plug 2 and the charging port 6 is correct at this time, the abutment sensor at the front end of the hollow plug adsorption ring 3 is triggered to transmit the induction signal to the plug-in induction unit, and the plug-in induction unit transmits the induction data to the anti-spontaneous combustion processing unit. The anti-spontaneous combustion processing unit determines that the plug-in state is good at this time and can be powered on normally, and then it has no effect, so that the charging control system in the charging pile control box 1 can continue the charging command; if the charging pile plug 2 and the charging port 6 are not plugged in properly at this time, then the hollow plug adsorption ring 3 is triggered to transmit the induction signal to the plug-in induction unit, and the plug-in induction unit transmits the induction data to the anti-spontaneous combustion processing unit. The anti-spontaneous combustion processing unit determines that the plug-in state is good at this time and can be powered on normally, and then it has no effect, so that the charging control system in the charging pile control box 1 can continue the charging command. The abutment sensor at the front end of the plug-in adsorption ring 3 is not triggered, and at the same time, the unchanged data or the data with little change is transmitted to the plug-in sensing unit, and the plug-in sensing unit transmits the sensing data to the anti-spontaneous combustion processing unit. The anti-spontaneous combustion processing unit determines that the charging pile plug 2 is not plugged in at this time according to the data, and then transmits the reminder data to the operation reminder unit. The operation reminder unit plays an image reminder of the unplugging through the display on the charging pile control box 1, and sends a voice reminder of the unplugging through the voice player on the charging pile control box 1, so that the charging operator can correct and plug in the position of the charging pile plug 2, ensure the connection stability between the charging pile plug 2 and the charging port 6 during the charging process, and ensure the charging safety;

[0040] During normal charging, the charging control system simultaneously monitors the battery status of the new energy vehicle, the power data and temperature data of the monitor, and transmits them to the power sensing unit and the temperature sensing unit synchronously respectively. At the same time, the temperature sensing probe located in the charging pile plug 2 also transmits the temperature data of the charging pile plug 2 to the temperature sensing unit in real time. The power sensing unit and the temperature sensing unit transmit the power data and the temperature data to the anti-spontaneous combustion processing unit respectively. The anti-spontaneous combustion processing unit judges these data. When it is judged that the power is not full and the temperature is normal, no action is taken. When it is judged that the power is full or the temperature is continuously too high, the control instruction is transmitted to the plug-in control unit, so that the plug-in control unit passes current to the bidirectional electromagnetic block 42, so that the two bidirectional electromagnetic blocks 42 produce magnetic effects of like repulsion, driving the elastic ring 41 to produce elongation deformation, thereby propping up the connection between the charging pile plug 2 and the charging port 6, so that the plug shell 21 is detached from the charging port 6, blocking the state of continuous charging. And the anti-spontaneous combustion processing unit simultaneously transmits the abnormal data to the abnormal feedback unit, so that the abnormal feedback unit transmits the abnormal data to the charging control system, so that the charging control system makes an emergency response, such as timely cutting off the power supply of the charging pile plug 2, cooling the battery, issuing an alarm signal, and sending abnormal data to the charging pile maintenance platform and other response measures, effectively avoiding damage caused by continuous charging, reducing the accident rate, and being able to protect the charging pile and new energy vehicles by monitoring the internal factors of the charging process, avoiding the problem of spontaneous combustion of the charging pile during the charging process, effectively improving the safety of the charging process, and effectively achieving the effect of physical disconnection by actively disengaging the charging pile plug 2, further ensuring the safety of electricity use, improving the protection effect of the charging pile, directly blocking the continuous influence of internal factors, ensuring the battery safety of new energy vehicles and the safety of the charging pile plug 2 of the charging pile, avoiding the occurrence of problems such as leakage, while reducing resource loss, it also effectively promotes the economic benefits of the charging pile.

[0041] Second implementation method:

[0042] Figure 1-10 It is shown that a conductive contact piece 31 is embedded at the rear end of the hollow plug-in adsorption ring 3, and the rear end of the conductive contact piece 31 is electrically connected to the auxiliary guide block 44, and an electromagnetic adjustment block 32 abutting against the conductive contact piece 31 is fixedly connected to the rear inner wall of the hollow plug-in adsorption ring 3, and the hollow plug-in adsorption ring 3 and the elastic ring 41 are both made of magnetic isolation materials or their inner walls are coated with magnetic isolation coatings. The arrangement of the auxiliary guide block 44, the elastic ring 41, the hollow plug-in adsorption ring 3 and the conductive contact piece 31 can effectively realize the electromagnetic control of the electromagnetic adjustment block 32 while effectively blocking the mutual electromagnetic influence between the electromagnetic adjustment block 32 and the bidirectional electromagnetic block 42, thereby playing an effective magnetic isolation role and ensuring the effectiveness of the regulation of the charging pile plug 2.

[0043] Figure 3-10It is shown that a plurality of negative pressure stabilizing components 5 cooperating with the hollow plug-in adsorption ring 3 are arranged in the hollow plug-in adsorption ring 3, and the negative pressure stabilizing component 5 includes a sealing rubber strip 51 slidably arranged at the front end of the hollow plug-in adsorption ring 3, and the front end of the sealing rubber strip 51 extends to the outside of the hollow plug-in adsorption ring 3, and the rear end of the sealing rubber strip 51 is fixedly connected with a slide rod 52, and the hollow plug-in adsorption ring 3 is also fixedly connected with a limit block 53 located between the sealing rubber strip 51 and the electromagnetic adjustment block 32, and the rear end of the slide rod 52 passes through the limit block 53, the slide rod 52 and the limit block 53 are slidably matched, and are fixedly connected with an adsorption iron block 54 cooperating with the electromagnetic adjustment block 32, through the sealing The movement of the blocking rubber strip 51 in the hollow plug-in adsorption ring 3 can realize the negative pressure adsorption effect of the plug-in end face when the charging pile plug 2 and the charging port 6 are plugged in, thereby effectively ensuring the stability of the connection between the charging pile plug 2 and the charging port 6, while avoiding the falling off and displacement of the charging pile plug 2 caused by external force. When the charging operator plugs in poorly, it can also cooperate with the anti-spontaneous combustion component 4 to realize the function of autonomous auxiliary plugging, effectively ensuring the effectiveness of the connection between the charging pile plug 2 and the charging port 6 during the charging process, avoiding problems such as leakage and poor contact, and ensuring the safety of the charging pile during charging while reducing the damage to the charging pile plug 2.

[0044] Figure 1-10 It is shown that the output end of the anti-spontaneous combustion treatment unit is also connected to a stabilizing control unit, and the output end of the stabilizing control unit is connected to the auxiliary guide block 44 signal. The stabilizing control unit controls the power on and off of the electromagnetic adjustment block 32 and the magnitude of the current passing therein through the cooperation of the auxiliary guide block 44 and the conductive contact 31. The cooperation of the stabilizing control unit can realize the automatic control of the negative pressure stabilizing component 5, so that the charging pile plug 2 and the charging port 6 are continuously locked during the charging process, and can also produce an active unlocking effect after charging is completed, effectively improving the intelligence and safety of the charging pile.

[0045] Fig. 9 and Fig.10 It is shown that the front end of the adsorption iron block 54 is fixedly connected to an elastic member 55 adjusted on the slide rod 52, and the front end of the elastic member 55 is fixedly connected to the limit block 53. The setting of the elastic member 55 can promote the resetting effect of the sealing rubber strip 51, maintain the sealing effect of the end face of the hollow plug-in adsorption ring 3 when not charging, and avoid the entry of dust. While saving resource loss, the durability of the hollow plug-in adsorption ring 3 and the negative pressure stabilizing assembly 5 is guaranteed.

[0046] Figure 1-10It is shown that after the anti-spontaneous combustion processing unit receives the sensing data transmitted by the plug-in sensing unit and determines that the plug-in of the charging pile plug 2 and the charging port 6 is completed, the anti-spontaneous combustion processing unit sends an adsorption instruction to the stable connection control unit, so that the stable connection control unit controls the electromagnetic adjustment block 32 to generate magnetism through the auxiliary guide block 44 and the conductive contact piece 31, and magnetically adsorbs the adsorption iron block 54, so that the adsorption iron block 54 drives the slide bar 52 to move, and the slide bar 52 drives the sealing rubber strip 51 to move backward in the hollow plug-in adsorption ring 3 under the guidance of the limit block 53, and then adsorbs the air between the plug-in surfaces of the hollow plug-in adsorption ring 3 and the charging port 6 at this time, so that a vacuum or negative pressure adsorption is gradually formed between the hollow plug-in adsorption ring 3 and the charging port 6, and the position of the charging pile plug 2 is limited through the adsorption stability of the hollow plug-in adsorption ring 3 and the charging port 6, thereby improving the connection stability of the charging pile plug 2 and the charging port 6, effectively avoiding the situation where the charging pile plug 2 is affected by external force and produces displacement during the charging process, and effectively ensuring the safety of charging;

[0047] When the anti-spontaneous combustion processing unit receives the sensing data transmitted by the plug-in sensing unit and determines that the charging pile plug 2 and the charging port 6 are not properly plugged in, and the charging pile plug 2 is still not plugged in after the reminder of the operation reminder unit, or when the charging pile plug 2 is displaced and detached due to external force during the subsequent charging process, the anti-spontaneous combustion processing unit autonomously controls the plug-in of the charging pile plug 2. First, the instructions are transmitted to the plug-in control unit respectively, and the plug-in control unit controls the bidirectional electromagnetic block 42 to generate a repulsive electromagnetic force, so that the elastic ring 41 is stretched and deformed, driving the hollow plug The adsorption ring 3 moves forward until the front end of the hollow plug-in adsorption ring 3 contacts the plug-in surface of the charging port 6, and the abutment sensor transmits an abutment sensing signal to the abutment sensing unit, and the plug-in sensing unit transmits the sensing data to the anti-spontaneous combustion processing unit. After the anti-spontaneous combustion processing unit determines that the hollow plug-in adsorption ring 3 has completed abutment, it sends an adsorption instruction to the stable connection control unit, so that the stable connection control unit controls the electromagnetic adjustment block 32 to generate magnetism through the auxiliary guide block 44 and the conductive contact piece 31, and magnetically adsorbs the adsorption iron block 54. The adsorption iron block 54 drives the slide bar 52 to move, and the slide bar 52 drives the sealing rubber strip 51 to move backward in the hollow plug-in adsorption ring 3 under the guidance of the limit block 53, and the position where the hollow plug-in adsorption ring 3 and the abutment surface of the charging port 6 are in contact with each other is maintained by vacuum or negative pressure, so that the hollow plug-in adsorption ring 3 is stably adsorbed on the abutment surface of the charging port 6, and then the anti-spontaneous combustion processing unit transmits the control instruction to the plug control unit, and the plug control unit controls the two bidirectional electromagnetic blocks 42 at this time to produce a magnetic force of attraction, so that the two bidirectional electromagnetic blocks 42 are attracted to each other. The electromagnetic block 42 drives the elastic ring 41 to contract. Under the action of the hollow plug adsorption ring 3 and the charging port 6 adsorption restriction, the elastic ring 41 contracts and drives the plug housing 21 to continuously move closer to the charging port 6 until the charging pile plug 2 and the charging port 6 are plugged in, thereby effectively realizing the role of autonomous auxiliary plugging, ensuring the stability of the connection between the charging pile plug 2 and the charging port 6 during the charging process, avoiding problems such as leakage and poor contact, and ensuring the safety of the charging pile during charging while reducing the damage to the charging pile plug 2;

[0048] And after the self-disconnection anti-spontaneous combustion protection action generated by the anti-spontaneous combustion processing unit due to the battery temperature being too high or the charging pile plug 2 being too high and the battery power being not fully charged, if the temperature is subsequently restored, under the adsorption limit of the hollow plug adsorption ring 3 and the negative pressure stabilizing component 5, it is ensured that the charging pile plug 2 and the charging port 6 will not be completely disconnected, and the anti-spontaneous combustion processing unit can autonomously plug and regulate the charging pile plug 2, and produce the effect of active plugging and continuing charging, thereby improving the anti-spontaneous combustion effect of the charging pile, and can also effectively improve the intelligent effect of the charging pile, and ensure the continuity of charging;

[0049] After charging is completed, the anti-spontaneous combustion processing unit transmits instructions to the stable connection control unit, so that the stable connection control unit cuts off the electrical signal of the auxiliary guide block 44, thereby causing the electromagnetic adjustment block 32 to be powered off and lose its magnetism, thereby releasing the magnetic adsorption effect on the adsorption iron block 54. At this time, the adsorption iron block 54 moves forward under the elastic recovery action of the elastic member 55, and then drives the sealing rubber strip 51 to move forward in the hollow plug-in adsorption ring 3 through the sliding rod 52, so that the gas in the hollow plug-in adsorption ring 3 is gradually released, releasing the vacuum or negative pressure adsorption state of the contact surface with the charging port 6, so that the charging pile plug 2 can be detached from the charging port 6, which is convenient for charging operation.

[0050] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
