Description

Technical Field

[0001] The present application relates to the technical field of charging piles, and more specifically, to a gun head socket and a charging pile. Background Art

[0002] In public charging places, due to the high utilization rate of charging piles and a wide range of user groups, the probability of damage to the gun head of the charging gun is relatively high. Some consumers casually discard the gun head of the charging gun and do not insert the gun head of the charging gun into the gun head socket, resulting in the gun head being exposed to the external environment for a long time and being eroded by natural factors such as wind, sun, rain, and snow. As time goes by, some parts of the gun head may deteriorate due to aging, wear, etc., leading to a decline in performance and then causing damage to the gun head. Although some damaged gun heads can still charge normally, this will bring great potential safety hazards, generating sparks or short - circuit phenomena and increasing the risk of fire. Some charging stations have administrators who will check daily and handle problems in a timely manner when abnormalities are found. However, some charging stations do not have administrators, so problems cannot be discovered quickly.

[0003] In summary, how to solve the problem that it is easy to bring potential safety hazards due to the failure to detect in time after the gun head of the charging gun is damaged has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0037] The core of the present application lies in providing a gun head socket and a charging pile to solve the problem that it is not easy to detect in time when the gun head of the charging gun is damaged, which is likely to bring potential safety hazards.

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0039] With the rapid development of new energy vehicles, the use of charging piles is more extensive. Among them, the charging pile includes a charging gun 2 and a gun head socket that matches the charging gun 2. The main function of the gun head socket is to place the charging gun 2 in a non-use state, so as to protect the gun head 21 of the charging gun 2 in the non-use state, so that the gun head 21 is not eroded by natural factors such as wind, sun, rain, and snow in the external environment. However, in the actual use process, there may be some consumers who randomly discard the gun head of the charging gun and do not insert the gun head of the charging gun into the gun head socket, resulting in the gun head being exposed to the external environment for a long time and being eroded by natural factors such as wind, sun, rain, and snow. As time goes by, some parts of the gun head may have a decline in performance due to aging, wear, etc., which may lead to damage to the gun head. Although some damaged gun heads can still charge normally, this will bring great potential safety hazards, such as generating sparks or short circuits, increasing the risk of fire. Some stations have administrators who will check daily and deal with problems in time when abnormalities are found, but some stations do not have administrators and cannot quickly discover problems.

[0040] Based on this, in the first aspect, the embodiments of the present application provide a new type of gun head socket to be able to timely detect the damage of the gun head of the charging gun. Specifically, referring to Figures 1-5 As shown, the gun head socket specifically includes a gun seat body 1, which can be specifically installed on the housing of the charging pile, or is arranged relatively independently of the housing of the charging pile. In the actual application process, it can be arranged according to the installation requirements, and no specific limitation is made here. Among them, at least one receiving cavity 11 adapted to the gun head 21 of the charging gun 2 is provided on the gun seat body 1. The number of the receiving cavities 11 can be one, or multiple (that is, two or more), and can be designed according to the number of the corresponding charging guns 2 on the charging pile. No more specific limitation is made here. Detection contacts 12 are circumferentially distributed on the inner cavity wall of the receiving cavity 11. When the gun head 21 of the charging gun 2 is inserted into the designated position of the receiving cavity 11, the detection contacts 12 are used to detect the defect condition of the circumferential wall surface of the gun head 21 corresponding to their positions.

[0041] In the actual application process of this gun head socket, when the gun head 21 of the charging gun 2 is inserted into the receiving cavity 11, each detection contact 12 can respectively detect the defect condition of the circumferential wall surface of the gun head 21 corresponding to the position where it is located. Since the detection contacts 12 are circumferentially distributed on the inner cavity wall of the receiving cavity 11, when there are defects on the circumferential wall surface of the gun head 21, the detection contacts 12 can detect them in time. When it is determined that the detection results of at least one detection contact indicate that there are defects in the gun head, it means that there are defects in the gun head, so that the damage of the gun head 21 of the charging gun 2 can be found in time, and then maintenance and repair can be carried out in time, greatly reducing the potential safety hazards. Among them, the detection results of the detection contacts 12 can be fed back to remote terminals such as the corresponding operation and maintenance platform, or can also be fed back to the corresponding on-site response agency or warning device, etc.

[0042] For those skilled in the art to better understand the technical solution provided by this application, the working principle will be briefly described below with reference to the accompanying drawings:

[0043] Refer to Figure 2 As shown, the circumferential surface of the gun head 21 of the charging gun 2 is in good condition. At this time, if the Figure 2 shown gun head 21 is inserted into the Figure 1 shown receiving cavity 11 of the gun head socket, the circumferential wall surface of the corresponding gun head 21 can be detected by the detection contacts 12 circumferentially distributed along the inner cavity wall of the receiving cavity 11, and the detection result is that there are no defects in the gun head 21.

[0044] Refer to Figure 4 As shown, there is a damage notch 23 on the circumferential surface of the gun head 21 of the charging gun 2. At this time, if the Figure 4 shown gun head 21 is inserted into the Figure 1 shown receiving cavity 11 of the gun head socket, the circumferential wall surface of the corresponding gun head 21 can be detected by the detection contacts 12 circumferentially distributed along the inner cavity wall of the receiving cavity 11. Since the surface corresponding to the damage notch 23 is significantly different from other positions, the detection result of the detection contact 12 corresponding to this position will be significantly different from the detection results of other positions. The detection result corresponding to the detection contact 12 at the damage notch 23 can indicate that there are defects in the gun head 21.

[0045] In addition, it should be noted that refer to Figures 1-3, generally, a clamping part 22 is further arranged on the charging gun 2, and a clamping position adapted to the clamping part 22 can be arranged on the gun head socket. When the gun head 21 of the charging gun 2 is inserted into the accommodating cavity 11 to reach the set position, the clamping part 22 is clamped and matched with the clamping position. And for the convenience of operation, a corresponding pressing part or driving part can be designed on the corresponding charging gun 2 to drive the clamping part 22 to disengage from the clamping position. For example, the clamping part 22 is an elastic tongue structure, and the pressing part can drive the elastic tongue to deform so as to disengage from the clamping position. Of course, there may also be no pressing part or driving part. For example, under the action of an external force, the clamping part 22 can be forced to deform to disengage from the clamping position, and no specific limitation is made here.

[0046] In some specific implementation schemes, the above detection contact 12 can specifically include an elastic contact and a sensor; wherein, without the action of an external force, the elastic contact projects from the inner cavity wall of the accommodating cavity 11 towards the center of the accommodating cavity 11. After the gun head 21 in a good state is inserted into the accommodating cavity 11, the elastic contact retracts under the extrusion of the circumferential wall surface of the gun head 21; the sensor is used to detect the retraction condition of the elastic contact. Specifically, referring to Figure 3 As shown, if after the gun head 21 is inserted into the accommodating cavity 11, the sensor detects that the elastic contact retracts, the detection result corresponding to this position is good; referring to Figure 5 As shown, if after the gun head 21 is inserted into the accommodating cavity 11, the sensor does not detect that the elastic contact retracts, the detection result corresponding to this position is that there is a defect in the gun head 21. Among them, the sensor can feedback the detection result to the corresponding circuit, and the circuit is used to determine whether there is a defect in the gun head. For example, the first circuit mentioned in the following technical solution. By designing such a structural form, the detection function is realized by the sensor, making the structural design of the elastic contact easier. For example, the elastic contact can be configured as an elastic ball embedded in the inner cavity wall of the accommodating cavity 11; or, the elastic contact can also be configured as a spring contact.

[0047] It should be noted that the above sensor can specifically be configured as a position sensor. For example, the position change of the elastic contact is detected by the position sensor, or an optoelectronic sensor can also be used, as long as it can detect whether the elastic contact is compressed.

[0048] It is worth mentioning that whether the gun head 21 is inserted into the accommodating cavity 11 can be known by whether there is retraction of the elastic contact. Because when the gun head 21 is not inserted, all the elastic contacts are in the extended state. After the gun head 21 is inserted into the accommodating cavity 11, since the circumferential wall surface of the gun head 21 cannot be damaged entirely, there must be some elastic contacts that will retract. Therefore, if it is detected that some elastic contacts are compressed within a certain period of time (such as 5 - 10 seconds, or other set time intervals), it indicates that the gun head 21 is inserted into the accommodating cavity 11.

[0049] In some other specific embodiments, the above-mentioned gun head socket may further include a first circuit electrically connected to the sensors of each detection contact 12. The first circuit is configured to determine that the gun head is intact when the feedback results of all sensors are in the retracted state after the gun head 21 is inserted into the receiving cavity 11 to a specified position, and determine that the gun head 21 has a defect when the feedback result of at least one sensor is in the non-retracted state. For example, in the first circuit, the feedback result of the "retracted state" can be specifically reflected as "1" in the "0 / 1" signal, and the feedback result of the "non-retracted state" in the first circuit can be specifically reflected as "0" in the "0 / 1" signal. After it is determined that the gun head 21 is inserted into the receiving cavity 11 to the specified position, as long as the first circuit receives a "0" in the "0 / 1" signal in the feedback result, it indicates that there is a defect on the surface of the gun head 21.

[0050] In addition, the first circuit may also have the function of sending an operation and maintenance signal. For example, after the gun head 21 is inserted into the receiving cavity 11 to the specified position, the first circuit can send an operation and maintenance signal in response to the feedback result of at least one sensor being in the non-retracted state (that is, detecting a defect on the circumferential wall surface of the gun head 21). That is, among the detection results of each detection contact 12, whether the detection result of one detection contact 12 indicates that the gun head 21 has a defect, or the detection results of multiple (i.e., two or more) detection contacts 12 indicate that the gun head 21 has a defect, as long as there is a detection result of a detection contact 12 indicating that the gun head has a defect, then the first circuit will send an operation and maintenance signal. Specifically, the first circuit can send the operation and maintenance signal to terminals such as the cloud or an operation and maintenance platform. The terminal can remotely monitor whether the gun head of the charging gun is intact, and then can send someone for after-sales maintenance in a timely manner, improving the after-sales service efficiency.

[0051] In some specific embodiments, the above-mentioned detection contact 12 can also be directly configured in the form of a switch structure such as a proximity switch, a travel switch or a position switch. That is, at this time, the detection contact 12 has both the dual functions of elastic deformation and a sensor, and the detection contact 12 is directly connected to the corresponding circuit (such as the aforementioned first circuit) as an electrical switch. Of course, it can be understood that the detection contact 12 can also be designed as a certain sensor, through which the defect condition of the circumferential wall surface of the gun head 21 can be directly detected, such as a distance sensor that can detect the distance between the circumferential wall surface of the gun head 21 and the probe of the sensor.

[0052] In some other specific embodiments, referring to Figure 1 and Figure 3As shown, the detection contacts 12 are evenly distributed on the inner cavity wall of the accommodation cavity 11 and preferably cover the circumferential wall surface of the gun head 21. By designing such a structure, each position on the circumferential wall surface of the gun head 21 has a corresponding detection contact 12 for detection, so that the detection result is more accurate.

[0053] Of course, it can be understood that the above-described method of uniform distribution is only an example of the embodiments of the present application. In actual application, a non-uniform distribution method can also be designed. For example, more detection contacts 12 can be arranged on the inner cavity wall of the accommodation cavity 11 corresponding to the most vulnerable part on the circumferential wall surface of the gun head 21, and fewer detection contacts 12 can be arranged on the inner cavity wall of the accommodation cavity 11 corresponding to the part on the circumferential wall surface of the gun head 21 that is not easily damaged.

[0054] In some specific implementation schemes, a warning device can also be provided on the gun seat main body 1. The warning device is electrically connected to each detection contact 12, and when the detection result of at least one detection contact 12 indicates that the gun head 21 has a defect, the warning device outputs a warning message. For example, the warning device has a corresponding circuit, which can be specifically defined as a second circuit. The second circuit controls the warning device to emit a warning message in response to at least one detection contact 12 detecting a defect on the circumferential wall surface of the gun head 21 corresponding to its position. By designing this warning device, it can timely remind the user that the gun head 21 of the charging gun 2 may be damaged, without safety hazards. At that time, the user can use other charging guns 2 that do not emit warning messages, further improving the safety of use.

[0055] In a further implementation scheme, the warning device can specifically include an indicator warning device and / or an audio warning device. For example, the warning device includes an indicator warning device. When the gun head 21 is damaged, the display mode of the indicator warning device is frequent flashing of the light, or the light does not light up when the gun head 21 has no defect, and the light lights up when the gun head 21 has a defect. Another example is that the warning device includes an audio warning device. When the gun head 21 is damaged, the audio warning device directly emits a beeping sound or other warning sounds, or voice reminders, etc. Of course, the warning device can also include an indicator warning device and an audio warning device at the same time, and at that time, a dual warning effect can be achieved, avoiding the situation where one of them fails and cannot emit a warning.

[0056] On the other hand, the embodiments of the present application also provide a charging pile, including a charging gun and a gun head socket that is inserted and adapted to the charging gun. The gun head socket is the gun head socket described in any of the above solutions. Since the foregoing gun head socket has the foregoing technical effects, the charging pile having this gun head socket should also have corresponding technical effects, which will not be elaborated here.

[0057] In addition, it should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

Generally speaking, the terms "comprising" and "including" only indicate the inclusion of the clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. A method or device may also include other steps or elements. An element defined by the statement "comprising one..." does not exclude the existence of another identical element in the process, method, commodity, or device that includes the element.

[0059] Among them, in the description of the embodiments of this application, unless otherwise specified, " / " means "or". For example, A / B can mean A or B. The "and / or" herein is only a description of the association relationship of the associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.
