DETAILED DESCRIPTION

[0023] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0024] In the present disclosure, unless otherwise specified, directional words such as "up, down, high, low, top, bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. "Inside" and "outside" refer to the inside and outside of the outline of the corresponding component. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the accompanying drawings, the same mark in different drawings represents the same element. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.

[0025] The present disclosure relates to a charging gun that can disconnect the charging gun from the power supply body when the charging gun overheats due to charging, and prevent the charging gun from falling off the power supply body, causing safety risks. Figure 1、 Figure 2 and Figure 3 The charging gun disclosed in the present invention includes a charging gun body 1, an overheating protection component 2 and a first locking component 3. The charging gun body 1 constitutes the main body of the charging gun, which can be connected to the vehicle through a cable, and can also complete the docking between the charging gun and the power supply body. The overheating protection component 2 can open or close the charging gun body 1 according to the temperature of the charging gun body 1, and the temperature threshold can be set in advance. The first locking component 3 can lock the charging gun body 1 with the power supply body when the charging gun body 1 is converted from an open state to a closed state through the overheating protection component 2. The power supply body can be a conventional power supply component such as a charging pile. By setting the first locking component 3, the charging gun body 1 can be prevented from falling from the power supply body when it is converted from an open state to a closed state, thereby avoiding the situation where the charging port of the charging gun body 1 is burned due to the gun being pulled out with power.

[0026] The charging gun disclosed in the present invention is able to close the charging gun body 1 in time to prevent the charging gun body 1 from being burned due to high temperature by providing an overheating protection component 2 when the charging gun body 1 is overheated due to charging, which makes it convenient for users to deal with the situation where the charging gun generates high temperature due to charging, and reduces the user's operating steps. In addition, by providing a first locking component 3, the charging gun body 1 can be locked with the power supply body when the charging gun body 1 is converted from an open state to a closed state through the overheating protection component 2, thereby preventing the charging gun body 1 from falling from the power supply body when it is converted from an open state to a closed state, causing the charging gun to be pulled out with power on, causing the charging port of the charging gun body 1 to be burned, thereby ensuring that the charging gun disclosed in the present invention has good safety.

[0027] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The overheat protection component 2 includes a control component 21 and a detection component 22. The detection component 22 can detect the temperature of the charging gun body 1 and can be a conventional component such as a temperature sensor. The control component 21 can control the opening or closing of the charging gun body 1 according to the temperature of the charging gun body 1, that is, the temperature detected by the detection component 22, and can synchronously control the first locking component 3 to lock the charging gun body 1 and the power supply body when the charging gun body 1 is switched from the open state to the closed state. By setting the detection component 22, the temperature of the charging gun body 1 can be detected in real time. When the temperature of the charging gun body 1 is too high, the detection component 22 can transmit the temperature information to the control component 21, so that the control component 21 can close the charging gun body 1 to prevent the charging gun body 1 from being damaged due to high temperature. When closing the charging gun body 1, it can also synchronously control the activation of the first locking component 3 to lock the charging gun body 1 and the power supply body to prevent the charging gun from being pulled out while it is energized, which causes the charging port of the charging gun body 1 to burn.

[0028] In one embodiment of the present disclosure, see Figure 1 and Figure 4The control member 21 includes a control switch 211 and a movable member 212. The control switch 211 can turn the charging gun body 1 on and off, and control the first locking member assembly 3 to lock and unlock the charging gun body 1 and the power supply body. The movable member 212 is fixedly connected to the charging gun body 1 and can move relative to the charging gun body 1 toward or away from the control switch 211 to activate and deactivate the control switch 211. In some embodiments, the control switch 211 can be a button provided on the charging gun body 1, which drives the circuit in the charging gun body 1 to turn on and off the charging gun body 1 and the first locking member 3, or it can be a mechanical structure, which turns on and off the charging gun body 1 and the first locking member 3 through transmission between mechanical structures.

[0029] The movable member 212 can move relative to the charging gun body 1 toward or away from the control switch 211 to activate or deactivate the control switch 211. The direction of movement toward the control switch 211 and the opening and closing of the movable member 212 can be determined based on the temperature detected by the detection member 22. For example, the movable member 212 is driven by a motor, and the detection member 22 is a temperature sensor. The temperature sensor can control the start and shut down of the motor through components such as a thermistor or a contactor, so that the movable member 212 can move toward or away from the control switch 211 based on the temperature of the charging gun body 1 to activate or deactivate the charging gun body 1 and the first locking assembly 3. Of course, in other embodiments, the control member 21 can also have other structures, which can be determined based on actual conditions, and the present disclosure does not limit this.

[0030] In one embodiment of the present disclosure, see Figure 1 and Figure 4 The movable member 212 includes an electric push rod 213 and an abutting rod 214, wherein the electric push rod 213 is fixedly connected to the charging gun body 1, and the abutting rod 214 is fixedly connected to the movable end of the electric push rod 213. The power source of the electric push rod 213 can also be connected to the detection member 22, so that the power source of the electric push rod 213 can control the activation and deactivation of the electric push rod 213 according to the detection temperature of the detection member 22. For example, the power source of the electric push rod 213 is a motor, and the detection member 22 is a temperature sensor. The temperature sensor can control the activation and deactivation of the motor through components such as a thermistor or a contactor, so that the electric push rod 213 can drive the abutting rod 214 to move toward or away from the control switch 211, so that the abutting rod 214 can activate and deactivate the control switch 211, thereby activating and deactivating the charging gun body 1 and the first locking assembly 3 through the control switch 211. Of course, in other embodiments, the movable member 212 can also have other structures, which can be determined according to actual conditions, and this disclosure is not limited to this.

[0031] In one embodiment of the present disclosure, see Figure 1 and Figure 7The first locking assembly 3 includes a first locking rod 31 and a reset member 32, wherein the first locking rod 31 is connected to the charging gun body 1 and can lock the charging gun body 1 with the power supply body under the drive of the control member 21 when the charging gun body 1 is switched from the open state to the closed state, and the reset member 32 can drive the first locking rod 31 to separate from the power supply body when the charging gun body 1 is switched from the closed state to the open state, so as to separate the charging gun body 1 from the power supply body. In some embodiments, the first locking rod 31 can extend in the same direction as the charging gun body 1 and be located in the charging gun body 1, and the end of the first locking rod 31 can also protrude from the charging gun body 1, so that the first locking rod 31 can directly contact and lock the power supply body under the drive of the control member 21, and can be promptly separated from the power supply body to complete the unlocking under the drive of the reset member 32. Of course, in other embodiments, the first locking assembly 3 can also have other structures, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0032] In one embodiment of the present disclosure, see Figure 1 and Figure 7 A accommodating cavity 11 is provided in the charging gun body 1, and the first locking rod 31 is located in the accommodating cavity 11, and the connecting end of the first locking rod 31 is connected to the accommodating cavity 11, and the locking end can protrude from the charging gun body 1. The structure of the locking end can be hook-shaped, so that the locking end can cooperate with the groove and other structures on the power supply body to complete the locking. When locking, taking the control member 21 including the control switch 211 as an example, the moving member 212 can drive the control switch 211 to move, so that the control switch 211 can drive the locking end of the first locking rod 31 toward the Move in the direction close to or away from the power supply main body so that the locking end of the first locking rod 31 can cooperate with the power supply main body to complete the locking. When resetting, the reset member 32 can be a reset spring, one end of the reset spring is connected to the accommodating cavity 11, and the other end is in contact with the first locking rod 31. When the control switch 211 is no longer pressed against the first locking rod 31, the end of the reset spring can drive the locking end of the first locking rod 31 to move in the direction away from the power supply main body through elastic force, so that the locking end of the first locking rod 31 can be separated from the power supply main body to complete the unlocking. Of course, in other embodiments, the linkage between the first locking rod 31 and the control member 21 can also adopt other forms, as long as the locking and unlocking between the first locking rod 31 and the power supply main body can be completed. The specific form can be determined according to actual conditions, and the present disclosure does not limit this.

[0033] In one embodiment of the present disclosure, see Figure 1 and Figure 7A locking head 12 protruding from the charging end of the charging gun body 1 is provided. The locking head 12 can be rectangular, with an opening on the side facing the power supply body. The locking end of the first locking rod 31 is located in the locking head, so that the locking end of the first locking rod 31 can protrude from the charging end of the charging gun body 1, so as to facilitate the locking end and the power supply body to be locked together. When cooperating with the power supply body, the locking end of the first locking rod 31 can extend through the opening to the locking head 12 and lock with the power supply body. When unlocking is required, it can also be retracted into the locking head 12 through the opening. By providing the locking head 12, the locking end of the first locking rod 31 can be prevented from being directly exposed to the outside of the charging gun body 1, which is easily damaged by the external environment, thereby making it difficult for the charging gun body 1 to lock with the power supply body during power-off, which may cause accidents.

[0034] In one embodiment of the present disclosure, see Figure 1 and Figure 7 The charging gun disclosed herein also includes a high-temperature protection component 4. This component can disengage the first locking component 3 from the power supply body when the first locking component 3 fails due to high temperature and is difficult to disengage from the power supply body, thereby unlocking the charging gun body 1 from the power supply body. The provision of the high-temperature protection component 4 prevents the user from having difficulty separating the charging gun body 1 locked to the power supply body after the first locking component 3 is damaged by high temperatures caused by a short circuit or other reasons. This significantly improves the safety of the charging gun disclosed herein and prevents accidents.

[0035] In one embodiment of the present disclosure, see Figure 7 and Figure 8 Taking the first locking assembly 3 as an example, the first locking lever 31 is used to lock the charging gun body 1 with the power supply body through its locking end. The high-temperature protection assembly 4 includes an abutment 41 and a blocking member 42. When the first locking assembly 3 fails due to high temperature, the abutment 41 can move the locking end of the first locking lever 31 away from the power supply body, allowing the locking end to disengage from the power supply body and unlock the first locking lever 31 from the power supply body. The blocking member 42 can block the abutment 41 when the first locking assembly 3 is not invalid, preventing the abutment 41 from affecting the normal use of the first locking assembly 3. If the first locking assembly 3 is damaged due to high temperature, the abutment 41 can be released in time to drive the locking end of the first locking assembly 3 away from the power supply body. Of course, in other embodiments, the high-temperature protection assembly 4 can also have other structures, as long as it can unlock the first locking assembly 3 at high temperatures. The specific structure can be determined according to actual conditions and is not limited by this disclosure.

[0036] In one embodiment of the present disclosure, see Figure 7 and Figure 8, a accommodating chamber 11 is provided in the charging gun body 1, and the abutment 41, the blocking member 42 and the first locking rod 31 are all located in the accommodating chamber 11, wherein the abutment 41 includes a first power member 411 and an abutment column 412, and the first power member 411 is connected to the accommodating chamber 11, and can be a component such as a spring or a shrapnel that provides power through elastic force to avoid the first power member 411 from failing due to high temperature. When connecting, the power end of the first power member 411 can be connected to the abutment column 412 so that the power provided by the first power member 411 can drive the abutment column 412 to move, and the abutment column 412 can move toward the first locking rod 31 through the power provided by the first power member 411, forcibly driving the first locking rod 31 to separate from the power supply body, so as to complete the unlocking between the charging gun body 1 and the power supply body, and avoid the charging gun body 1 being difficult to pull out from the power supply body under high temperature conditions.

[0037] The blocking member 42 includes a blocking plate 421 and a second power member 422. The blocking plate 421 can contact the abutment column 412 when the first locking assembly 3 has not failed, limiting the abutment column 412 from contacting the first locking rod 31 under the drive of the first power member 411. The second power member 422 is connected to the blocking plate 421, and can drive the blocking plate 421 to release the abutment column 412 in time when the first locking assembly 3 fails, so that the abutment column 412 can drive the first locking rod 31 to separate from the power supply body. For example, the second power member 422 can be made of two metals that fit together and have different thermal expansion coefficients. When the first locking assembly 3 has not failed due to high temperature, the blocking plate 421 can effectively prevent the abutment column 412 from moving. When the first locking assembly 3 fails due to high temperature, the two metals with different thermal expansion coefficients will bend and create a gap due to the difference in expansion coefficients. The gap and force generated by the bending can then drive the blocking plate 421 to move away from the abutment column 412, releasing the abutment column 412, and then detaching from the power supply body through the first locking rod 31 carried by the abutment column 412. Of course, in other embodiments, the abutment member 41 and the blocking member 42 can also have other structures, as long as they can complete the unlocking of the first locking assembly 3 at high temperatures. The specific structure can be determined according to actual conditions and is not limited by the present disclosure.

[0038] In one embodiment of the present disclosure, see Figure 1 and Figure 7The charging gun disclosed herein also includes a second locking assembly 5, which can lock the charging gun body 1 with the power supply body when the charging gun body 1 is in the open state. By providing the second locking assembly 5, the stability of the charging gun body 1 in the charging state can be ensured, and the charging gun body 1 can be prevented from falling off from the power supply body due to external factors, etc., which in turn causes the charging gun to be pulled out while energized, resulting in the burning of the charging port of the charging gun body 1. In addition, by providing the second locking assembly 5, it can also prevent the charging gun body 1 from falling off from the power supply body when the first locking assembly 3 fails when switching from the open state to the closed state, playing a double insurance role, further improving the safety and stability of the charging gun disclosed herein.

[0039] In one embodiment of the present disclosure, see Figure 1 and Figure 7 The second locking assembly 5 includes a second locking rod 51, a pressing member 52 and a locking switch 53. A accommodating cavity 11 is provided in the charging gun body 1. The connecting end of the second locking rod 51 is connected to the accommodating cavity 11, and the locking end protrudes out of the charging gun body 1, for example, is located in the lock head 12. The pressing member 52 can press the second locking rod 51 to a state where it is locked with the power supply body. It can be a torsion spring, etc. The locking switch 53 can drive the second locking rod 51 to overcome the force of the pressing member 52 and restore it to a state of being detached from the power supply body.

[0040] When it is necessary to lock the second locking rod 51 with the power supply body, it is necessary to adjust the second locking rod 51 to a state of being disengaged from the power supply body through the locking switch 53, and then insert the second locking rod 51 into the power supply body along with the charging gun body 1, and then release the locking switch 53. The second locking rod 51 will be locked with the power supply body under the action of the fastening member 52. This setting can prevent users from forgetting to use the second locking assembly 5, so as to ensure the safety of the charging gun disclosed in the present invention. Of course, in other embodiments, the second locking assembly 5 can also be of other structures, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0041] In one embodiment of the present disclosure, see Figure 1 、 Figure 5 and Figure 6 The charging gun of the present disclosure also includes a heat dissipation assembly 6, which is connected to the charging gun body 1 and can dissipate heat from the charging gun body 1. By providing the heat dissipation assembly 6, the charging gun body 1 can dissipate heat during charging, when the charging gun body 1 stops due to overheating, and after charging is completed, thereby improving the safety of the charging gun body 1 during the charging process and extending the service life of the charging gun body 1.

[0042] In one embodiment of the present disclosure, see Figure 1 、 Figure 5 and Figure 6The heat dissipation assembly 6 includes heat dissipation fins 61 and a heat dissipation fan 62. The heat dissipation fins 61 are arranged around the charging gun body 1 and are fixedly connected to the outer surface of the charging gun body 1 so that the heat dissipation fins 61 can fully dissipate heat from the charging gun body 1. The heat dissipation fan 62 is arranged toward the charging gun body 1 and is fixedly connected to the charging gun body 1. The fixed connection method can be fixed by a rod so that the heat dissipation fan 62 can better dissipate heat from the charging gun body 1. Of course, in other embodiments, the heat dissipation assembly 6 can also have other structures, which can be determined according to actual conditions and are not limited in this disclosure.

[0043] When the charging gun disclosed herein is in use, the temperature of the charging gun body 1 can be detected by the detection component 22 in the overheat protection component 2. When the temperature of the charging gun body 1 is overheated, the charging gun body 1 can be closed by the control component 21. In the process of closing the charging gun body 1, the control component 21 can also drive the first locking rod 31 in the first locking component 3 to lock with the power supply body, so as to prevent the charging gun body 1 from falling from the power supply body when it is converted from the open state to the closed state, resulting in the problem of pulling out the gun while it is charged and damaging the charging end of the charging gun body 1. The charging gun disclosed herein also includes a high-temperature protection component 4, a second locking component 5 and a heat dissipation component 6. The high-temperature protection component 4 can forcibly drive the first locking component 3 to separate from the power supply body when the first locking component 3 is damaged due to high temperature, thereby avoiding further damage to the charging gun body 1 and the occurrence of safety accidents. The second locking component 5 can lock the charging gun body 1 with the power supply body when the charging gun body 1 is charging, and can also serve as a double insurance when the first locking component 3 fails. The heat dissipation component 6 can dissipate heat for the charging gun body 1 during use of the charging gun body 1, thereby avoiding damage to the charging gun body 1 and increasing the service life of the charging gun body 1.

[0044] The second aspect of the present disclosure further provides a vehicle, including the charging gun described in the above embodiment, so that the vehicle of the present disclosure can be safer and more stable when charging. The connection between the charging gun and the power supply body, the different situations during the charging process, and the connection relationship between different components in the charging gun are the same as those described in the above implementation. Please refer to the description in the above embodiment and no further details will be given here.

[0045] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings.
