Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of charging equipment, and particularly relate to a charging gun and a charging equipment. BACKGROUND

[0002] With the wide application of new energy electric vehicles, charging equipment for charging electric vehicles has gradually become popular. The charging equipment includes a charging gun and a charging pile. In the use process, the charging gun is prone to falling to the ground. At this time, strong impact force can damage the gun head of the charging gun, and even damage the internal components, thereby causing poor contact of the components, and even the phenomenon that the gun head cannot be used, which seriously affects the service life and safety of the charging gun.

[0003] In the related art, the gun head and the shell are detachable, so that the gun head can be replaced when damaged. However, the phenomenon of gun head damage still exists, and it is difficult to solve the problem of gun head damage and non-use from the root. CONTENT OF THE UTILITY MODEL

[0004] Embodiments of the present application provide a charging gun and a charging equipment, which can solve the problem that the gun head is prone to falling and damaging, thereby affecting the service life and safety of the gun head.

[0005] In a first aspect, embodiments of the present application provide a charging gun, which includes a gun shell, a gun head, and a buffer layer. The gun head is arranged on the gun shell, and is used to be plugged with a charging structure of a vehicle. The buffer layer is arranged at an end of the gun head away from the gun shell, and is used to buffer the force acting on the gun head. For example, when the gun head is subjected to external force, the buffer layer can reduce the possibility of damage to the gun head.

[0006] When the gun head is plugged with the charging structure of the vehicle, the vehicle can be charged. In the use process of the charging gun, a user can hold the gun shell to plug the gun head with the charging structure of the vehicle. Due to the direction and posture of the user holding the gun shell, when the charging gun falls by accident, the gun head will first contact the ground, thereby causing the gun head to be prone to damage. The charging gun provided by embodiments of the present application can be provided with a buffer layer at an end of the gun head away from the gun shell. Therefore, when the charging gun falls, the buffer layer at the end of the gun head can first contact the ground. The buffer layer can absorb at least part of the impact force of the ground, so as to weaken the impact force of the ground acting on the gun head, thereby protecting the gun head from being damaged.

[0007] Therefore, in embodiments of the present application, the possibility of damage to the gun head when the charging gun falls can be reduced from the root, thereby reducing the possibility of increasing cost and maintenance workload caused by replacing the gun head. Moreover, the charging gun in embodiments of the present application has a simple structure, is easy to assemble, and has high operability.

[0008] In addition, it is easy to understand that damage of the gun head is likely to cause damage of internal components, thereby causing a safety hazard when the gun head is plugged into the vehicle again. In the embodiment of the application, the gun head can be buffered by the buffer layer, so that the internal components can also be protected from damage, thereby improving the safety of the charging gun.

[0009] It is easy to understand that the embodiment of the application can effectively reduce the increase of material cost and maintenance cost caused by replacing the entire gun head, and the gun head does not need to be replaced frequently.

[0010] In a possible implementation, the gun head has a first end and a second end in the plugging direction of the gun head, the first end is used for plugging with the charging structure, and the second end is used for connecting with the gun shell. At least part of the surface of the first end of the gun head is provided with a buffer layer.

[0011] Since the second end is used for connecting with the gun shell, and the longitudinal section of the gun shell is generally larger than the longitudinal section of the gun head. It can be understood that the longitudinal section of the gun shell and the longitudinal section of the gun head are both perpendicular to the plugging direction of the gun head. When the charging gun falls, the gun shell can protect the area of the gun head close to the second end from damage. The area of the gun head close to the first end is more likely to be damaged than the area close to the second end. Therefore, in the embodiment of the application, by providing the buffer layer on at least part of the surface of the first end of the gun head, the gun head can be protected without providing the buffer layer on the entire surface of the gun head, so that the protection of the gun head can be achieved by less buffer layer material, thereby reducing the material cost of the buffer layer.

[0012] In a possible implementation, the buffer layer is wrapped around the outer circumferential surface of the first end of the gun head.

[0013] In the embodiment of the application, the charging gun usually falls obliquely during the falling process. Therefore, compared with the end surface of the gun head away from the gun shell, the outer circumferential surface of the first end of the gun head is more likely to be damaged. In the embodiment of the application, by wrapping the buffer layer around the outer circumferential surface of the first end of the gun head, the outer circumferential surface of the area of the gun head close to the first end which is prone to damage can be protected, so as to more effectively reduce the possibility of damage of the gun head.

[0014] In a possible implementation, the gun head includes a mounting portion and a gun head body. The mounting portion is located at the first end, and the buffer layer is wrapped around the outer circumferential surface of the mounting portion. The gun head body is located at the second end, and the gun head body is connected with the gun shell.

[0015] The longitudinal section of the mounting portion is smaller than the longitudinal section of the gun head body.

[0016] In the embodiments of the present application, the buffer layer can be connected to the gun head body through the mounting portion. By setting the longitudinal section of the mounting portion to be smaller than the longitudinal section of the gun head body, the buffer layer can be conveniently sleeved outside the mounting portion, so that the outer circumferential surface of the buffer layer can not easily protrude from the outer circumferential surface of the gun head body, thereby reducing the possibility that the outer circumferential surface of the buffer layer protrudes from the outer circumferential surface of the gun head body and affects the insertion of the gun head into the vehicle.

[0017] In a possible implementation, the buffer layer can have a wall thickness. The wall thickness of the buffer layer can be in a range of about 5 mm to about 10 mm. When the wall thickness of the buffer layer 130 is in a range of about 5 mm to about 10 mm, the protection effect on the gun head 120 can be satisfied, and the thickness of the buffer layer 130 will not be too thick to increase the cost.

[0018] In a possible implementation, the buffer layer includes a buffer sleeve and a buffer pad connected to each other, the buffer sleeve is sleeved outside the mounting portion, and the buffer pad covers at least part of the end surface of the mounting portion away from the gun shell in the insertion direction of the gun head.

[0019] In the embodiments of the present application, the buffer layer can be wrapped around the outer circumferential surface of the mounting portion, and the buffer layer can also cover at least part of the end surface of the mounting portion away from the gun shell. The buffer layer can be wrapped around the entire outer surface of the mounting portion, so that the buffer layer and the gun head can have a larger contact surface, thereby more effectively reducing the possibility of damage to the gun head when the charging gun falls.

[0020] Specifically, since the mounting portion is located at the first end, and the outer circumferential surface of the mounting portion is a part of the gun head that is easily damaged, the buffer sleeve wrapped around the outside of the mounting portion can be used to protect the outer circumferential surface of the mounting portion. When the charging gun falls, the buffer sleeve can protect the outer circumferential surface of the gun head that is easily damaged.

[0021] Since the buffer pad is located at the end of the mounting portion away from the gun shell, in other words, the buffer pad is located at the end surface of the gun head away from the gun shell, and the buffer pad is connected to the buffer sleeve, when the charging gun falls and the end surface of the gun head away from the gun shell faces the ground, the buffer pad can first contact the ground. The buffer pad can be located between the ground and the gun head to absorb the impact force of the ground on the gun head, thereby protecting the end surface of the gun head away from the gun shell from the impact of the ground and reducing the possibility of damage to the gun head.

[0022] In a possible implementation, the buffer pad can be provided with a relief hole. Since the gun head is provided with an insertion hole, the relief hole can expose the insertion hole to facilitate the insertion of the connector of the charging structure of the vehicle.

[0023] In a possible implementation, a through hole matched with the insertion hole can be formed on the buffer pad. Since the gun head is provided with the insertion hole, by arranging the corresponding through hole, the connector of the charging structure of the vehicle can be inserted and connected with the terminal of the gun head.

[0024] In a possible implementation, the buffer layer covers the end surface of the gun head away from the gun shell along the insertion direction of the gun head, and the buffer layer extends along the insertion direction of the gun head.

[0025] In the embodiments of the present application, the buffer layer can cover the end surface of the gun head away from the gun shell, in other words, the buffer layer can cover the end surface of the first end of the gun head away from the gun shell. Moreover, since the buffer layer can have a thickness along the insertion direction of the gun head, when the charging gun falls, the outer circumferential surface of the buffer layer can first contact the ground to protect the area of the gun head close to the first end from being damaged.

[0026] It is easy to understand that, since the buffer layer has a thickness along the insertion direction of the gun head, when the outer circumferential surface of the mounting portion or the end surface of the mounting portion away from the gun shell faces the ground when the charging gun falls, the buffer layer can protect the gun head. The buffer layer can absorb the impact force of the ground to weaken the impact force received by the gun head, thereby protecting the gun head.

[0027] In a possible implementation, the longitudinal section of the buffer layer is matched with the shape of the longitudinal section of the gun head, and the longitudinal section of the buffer layer and the longitudinal section of the gun head are perpendicular to the insertion direction of the gun head.

[0028] In the embodiments of the present application, the outer contour of the buffer layer can be completely coincident with the outer contour of the gun head, so that the buffer layer is not easy to cause obstruction and affect the insertion of the gun head when the gun head is connected with the charging structure of the vehicle. Moreover, since the gun head is provided with the insertion hole for the connector of the charging structure of the vehicle to be inserted, correspondingly, the buffer layer can be provided with the through hole matched with the insertion hole, so that the connector of the charging structure can be inserted when the gun head is connected with the charging structure of the vehicle.

[0029] In a possible implementation, the outer circumferential surface of the buffer layer is flush with the outer circumferential surface of the gun head body.

[0030] In the embodiments of the present application, after the buffer layer is fixed to the gun head, the outer circumferential surface of the buffer layer can not exceed the outer circumferential surface of the gun head body, and the outer circumferential surface of the gun head body can also not exceed the outer circumferential surface of the buffer layer, so that the part of the gun head body for being inserted into the charging structure of the vehicle can be matched with the charging structure of the vehicle after the buffer layer is mounted, thereby avoiding that the buffer layer affects the insertion of the gun head into the charging structure of the vehicle.

[0031] In a possible implementation, the buffer layer and the gun head are integrally formed by injection molding; or the buffer layer is fixedly connected with the gun head by colloid.

[0032] In the embodiments of the present application, the buffer layer can form an integral structure with the gun head through an injection molding process or through a gluing process. The buffer layer forms an integral structure with the gun head, which can improve the connection reliability of the buffer layer and the gun head, avoid the possibility of the buffer layer falling off due to repeated plugging and unplugging of the charging gun. Moreover, the assembly process can be saved, the assembly efficiency can be improved, and the product cost can be reduced.

[0033] In a second aspect, the embodiments of the present application also provide a charging device, which includes the charging gun and the charging pile in any of the above embodiments.

[0034] The charging gun also includes a charging cable. The charging cable is connected with the gun shell. The charging gun is connected with the charging pile through the charging cable.

[0035] In the charging device of the embodiments of the present application, the gun head of the charging gun is provided with a buffer layer, which can absorb at least part of the impact force from the ground when the charging gun falls to the ground, so as to weaken the impact force on the gun head, thereby protecting the gun head and reducing the possibility of affecting vehicle charging caused by damage to the gun head, which is beneficial to improve the service life and use safety of the charging gun and improve the use reliability of the charging device.

[0059] The charging device provided by the embodiments of the present application can be used to provide energy supplement for a vehicle. It should be noted that the vehicle in the embodiments of the present application can be a pure electric vehicle or a hybrid vehicle, and is not limited. The vehicle will be described in the present application.

[0060] The main function of the charging device provided by the embodiments of the present application is to deliver the electric energy in the power grid to the battery pack of the vehicle. The charging device can provide charging services with different currents and voltages. A charging host can be arranged between the charging device and the power grid. The charging device, the power grid and the charging host realize the synergistic effect through data exchange to ensure safe and efficient charging.

[0061] The charging device can be installed in a public building (public building, shopping mall, public parking lot, etc.), parking lot or charging station of a residential area. The charging device can charge different types of vehicles according to different voltage levels.

[0062] The charging device includes a charging gun and a charging pile. The charging gun and the charging pile are used in cooperation. The charging pile is connected with a power grid. The charging gun serves as an intermediate link connecting the charging pile and the vehicle, and is mainly used for transmitting the electric energy provided by the charging pile to the battery pack of the vehicle, and is a connecting device for realizing the transmission of electric energy from the charging pile to the vehicle. After the charging gun is connected with the vehicle, the charging pile can charge the vehicle through the charging gun, so that the vehicle can store enough electric quantity to support its operation.

[0063] The gun head of the charging gun is used for being inserted into the vehicle to charge the vehicle. In the use process, the charging gun is easy to fall off. When the charging gun falls to the ground, the charging gun will collide with the ground intensively, thereby causing damage to the charging gun. In the falling process of the charging gun, usually, one end of the gun head first lands on the ground. The gun head will be impacted by the ground, and therefore, the gun head of the charging gun is easy to be damaged.

[0064] It is easy to understand that the damage of the gun head is easy to cause the gun head to be unable to be inserted into the charging structure of the vehicle, thereby affecting the normal use of the charging gun, and further affecting the travel of the user. Even, the damage of the gun head is easy to cause the damage of the internal components of the gun head, thereby affecting the safety in the use process of the charging gun, and further causing a safety hazard.

[0065] In the embodiment of the present application, the gun head of the charging gun can be provided with a buffer layer. Therefore, when the charging gun falls, the buffer layer at the end of the gun head can first contact the ground. The buffer layer can absorb at least part of the impact force of the ground, so as to weaken the impact force of the ground on the gun head, thereby protecting the gun head from being damaged.

[0066] Therefore, in the embodiment of the present application, the possibility of damage of the gun head when the charging gun falls can be reduced from the root, thereby reducing the possibility of increasing the cost and the maintenance workload caused by replacing the gun head. Moreover, the structure of the charging gun in the embodiment of the present application is simple, easy to assemble, and has high operability.

[0067] The charging gun 100 and the charging device 10 provided by the embodiment of the present application will be described in detail below through specific implementation manners.

[0068] Referring to Figure 1 , the charging device 10 includes a charging gun 100 and a charging pile 200. The charging gun 100 and the charging pile 200 are connected. The charging pile 200 can provide electric energy. After the charging gun 100 is connected with the charging structure of the vehicle, the charging pile 200 can charge the vehicle through the charging gun 100. The charging pile 200 can be fixed on the ground or the wall.

[0069] The charging gun 100 may include a gun housing 110 and a gun head 120. The gun head 120 can be inserted into the charging structure of a vehicle. The gun housing 110 is designed for easy gripping by the user. By holding the gun housing 110 and inserting the gun head 120 into the vehicle, the user can charge the vehicle.

[0070] See also Figure 1 The charging station 200 may include a power supply component 210. The power supply component 210 can provide power to the charging gun 100. Furthermore, the power supply component 210 can be electrically connected to the mains power supply via a charging host (not shown). The charging host can convert the current supplied by the mains power supply into the current required for vehicle charging.

[0071] It should be noted that the charging device 10 generates heat during the process of supplying power to the vehicle. To avoid the heat affecting charging performance and safety, the charging device 10 can be a liquid-cooled charging device or an air-cooled charging device, and this application embodiment does not limit the type of device.

[0072] The charging station 200 may include a housing 220. The power supply assembly 210 may be located within the housing 220. The housing 220 may protect the components within the charging station 200. For example, the charging station 200 may be a cabinet structure.

[0073] The charging gun 100 may also include a charging cable 300. The charging cable 300 can be led out from the gun housing 110 of the charging gun 100 for electrical connection with the charging pile 200, thereby realizing the electrical connection between the charging gun 100 and the charging pile 200.

[0074] The charging cable 300 may include conductive wire cores (not shown) and an insulating layer (not shown) covering the conductive wire cores. The two ends of the conductive wire cores may be connected to the charging gun 100 and the power supply assembly 210, respectively. The conductive wire cores can transfer power from the power supply assembly 210 to the charging gun 100, and then from the charging gun 100 to the vehicle. The charging cable 300 may include at least two conductive wire cores with opposite polarities.

[0075] In some examples, when the charging device 10 is a liquid-cooled charging device, the charging cable 300 may be provided with a liquid-cooling pipe 310 to improve the heat dissipation efficiency of the charging gun 100. The liquid-cooling pipe 310 may contact the insulation layer of the conductive wire core. The gun housing 110 may form an internal space for accommodating part of the conductive wire core and the liquid-cooling pipe 310.

[0076] For example, see [link to previous article] Figure 1The charging pile 200 may include a cooling distribution unit 230. The cooling distribution unit 230 is connected to the liquid cooling pipe 310. The cooling distribution unit 230 can be used to supply coolant to the liquid cooling pipe 310. By the flow of coolant in the liquid cooling pipe 310, the heat generated by the conductive wire core in contact with the liquid cooling pipe 310 can be cooled and dissipated.

[0077] In some examples, the coolant may be, but is not limited to, water, ethylene glycol, propylene glycol, synthetic oil, or other refrigerants.

[0078] The charging cable 300 may include at least two liquid cooling pipes 310. At least one liquid cooling pipe 310 is a liquid inlet pipe for supplying coolant at a lower temperature to the cable. At least one liquid cooling pipe 310 is a liquid return pipe for returning the coolant at a higher temperature to the cooling capacity distribution unit 230.

[0079] Specifically, the inlet pipe can supply coolant at a lower temperature to the conductive core. The coolant at a lower temperature can absorb heat from the conductive core, thus lowering its temperature. At this point, the coolant at a lower temperature absorbs heat and its temperature rises, forming a coolant at a higher temperature. The coolant at a higher temperature can then be returned to the cooling capacity distribution unit 230 via the return pipe.

[0080] The cooling distribution unit 230 can cool the high-temperature coolant to form a lower-temperature coolant, thereby achieving continuous heat dissipation for the conductive core.

[0081] The charging pile 200 may also be equipped with a pump (not shown). The pump can be used to power the flow of coolant so that the coolant can be delivered from the cooling capacity distribution unit 230 to the charging connector.

[0082] The charging pile 200 may also be equipped with a heat exchanger (not shown in the figure). Coolant flowing through the conductive core absorbs heat from the core, creating a higher-temperature coolant. The heat exchanger cools this higher-temperature coolant, thus continuously providing a lower-temperature coolant to the conductive core.

[0083] The cooling distribution unit 230, pump, heat exchanger and other structures can all be located inside the outer shell 220 of the charging pile 200.

[0084] In some examples, when the charging device 10 is an air-cooled charging device, the charging pile 200 may be equipped with an air-cooling device. The air-cooling device (not shown) may include components such as a fan and a heat sink. The heat sink may be connected to modules such as the power supply component 210 within the charging pile 200 that are prone to heat generation, so that heat can be transferred to the heat sink first. Then, the operation of the fan can circulate air to remove the heat from the heat sink to the outside of the casing 220 of the charging pile 200.

[0085] In some examples, the air-cooling device may also include an air duct (not shown). Heat on the heat sink can be released to the outside of the housing 220 via the air duct to improve the reliability of heat release, so that the temperature inside the charging pile 200 is not too high and affects charging efficiency and charging safety.

[0086] In one possible implementation, this application embodiment provides a charging gun 100, see [link to relevant documentation]. Figure 2 As shown, the charging gun 100 may include a gun housing 110, a gun head 120, and a buffer layer 130.

[0087] The nozzle 120 can be disposed on the housing 110. The nozzle 120 is used to connect with the charging structure of the vehicle (not shown). The buffer layer 130 can be disposed on the end of the nozzle 120 away from the housing 110. The buffer layer 130 can be used to buffer the force applied to the nozzle 120 when it is subjected to an external force.

[0088] When the charging gun head 120 is plugged into the vehicle's charging structure, it can charge the vehicle. While using the charging gun 100, the user can hold the gun housing 110 to plug the charging gun head 120 into the vehicle's charging structure. Since the charging gun 100 includes a charging cable 300 for electrical connection with the power supply component 210, the charging cable 300 can be located on the side of the gun housing 110 away from the charging gun head 120, so that the charging cable 300 will not interfere with the plugging and unplugging of the charging gun head 120 when the user holds the gun housing 110. Based on the user's holding posture of the gun housing 110, if the charging gun 100 is accidentally dropped, the charging gun head 120 will be the first to contact the ground, making the charging gun head 120 susceptible to damage.

[0089] In this embodiment, by providing a buffer layer 130 on the charging gun head 120, the buffer layer 130 can make contact with the ground first when the charging gun 100 is dropped. At this time, the buffer layer 130 is located between the ground and the charging gun head 120. The buffer layer 130 can absorb the larger impact force from the ground, thereby reducing the impact force on the charging gun head 120 and protecting it from damage. This helps to reduce the possibility of damage to the charging gun head 120 caused by a drop, and thus helps to improve the service life of the charging gun 100.

[0090] Furthermore, it is easy to understand that damage to the charging head 120 can easily lead to damage to internal components, thus potentially causing safety hazards when the charging head 120 is reconnected to the vehicle. In this embodiment, the charging head 120 can be buffered by the buffer layer 130, preventing damage to its internal components and improving the safety of the charging gun 100.

[0091] It is easy to understand that the embodiments of this application can effectively reduce the increase in material costs and maintenance costs caused by replacing the entire gun head 120, without the need for frequent replacement of the entire gun head 120.

[0092] In this application embodiment, the gun head 120 and the gun shell 110 can be separate structures, or the gun head 120 and the gun shell 110 can be an integral structure, and no limitation is made in the implementation of this application.

[0093] In some examples, to improve the heat dissipation efficiency of the charging gun 100, a liquid cooling pipe 310 can be provided inside the charging gun 100. In this case, the gun head 120 and the gun housing 110 can be an integral structure to avoid the possibility of leakage in the liquid cooling pipe 310 during the disassembly of the gun head 120, which could lead to a short circuit in the charging gun 100. Therefore, when the gun head 120 and the gun housing 110 are an integral structure, it is difficult to replace the gun head 120 if it is damaged. In this embodiment, when the gun head 120 cannot be disassembled from the gun housing 110, a buffer layer 130 can be provided on the gun head 120 to reduce the possibility of damage to the gun head 120.

[0094] In some examples, the gun head 120 may be formed from a high-strength plastic material. For example, the plastic material may be, but is not limited to, polycarbonate (PC) or polyamide (PA).

[0095] In some examples, the cushioning layer 130 may be made of a material with high damping performance. For example, the material of the cushioning layer 130 may be, but is not limited to, polyurethane foam or thermoplastic elastomer (TPE).

[0096] See also some of the possible implementation methods. Figures 2 to 8 As shown, along the insertion direction X of the gun head 120, the gun head 120 may have a first end 120a and a second end 120b. The first end 120a can be used to connect with the charging structure of a vehicle. The second end 120b can be connected to the gun housing 110. At least a portion of the surface of the first end 120a of the gun head 120 is provided with a buffer layer 130.

[0097] The first end 120a and the second end 120b can be located at the two ends of the gun head 120, respectively. Since the second end 120b can be connected to the gun housing 110, and the longitudinal section of the gun housing 110 is generally larger than that of the gun head 120, both the longitudinal sections of the gun housing 110 and the gun head 120 are perpendicular to the insertion direction X of the gun head 120. When the charging gun 100 is dropped, the gun housing 110 can protect the side of the gun head 120 near the second end 120b from damage. Therefore, the area of ​​the gun head 120 near the first end 120a is more susceptible to damage than the area near the second end 120b.

[0098] Therefore, in this embodiment of the application, by providing a buffer layer 130 on at least a portion of the surface of the first end 120a of the gun head 120, the gun head 120 can be protected without providing a buffer layer 130 on the entire outer surface of the gun head 120. This allows the gun head 120 to be protected with less material in the buffer layer 130, which helps to reduce the material cost of the buffer layer 130.

[0099] It should be noted that the provision of a buffer layer 130 on at least a portion of the surface of the first end 120a of the gun head 120 can mean that the buffer layer 130 is disposed on the outer peripheral surface of the gun head 120. Alternatively, it can mean that the buffer layer 130 is disposed on the end face of the gun head 120 away from the gun housing 110. Or, the buffer layer 130 may be disposed on both the outer peripheral surface of the gun head 120 and the end face away from the gun housing 110. No specific limitation is made in this embodiment.

[0100] See also some of the possible implementation methods. Figures 2 to 7 As shown, the buffer layer 130 can cover the outer peripheral surface of the first end 120a of the gun head 120.

[0101] During a drop, the charging gun 100 typically falls at an angle. Therefore, compared to the end face of the gun head 120 furthest from the gun housing 110, the outer peripheral surface of the gun head 120 near the first end 120a is more prone to damage. In this embodiment, by providing a buffer layer 130 to cover the outer peripheral surface of the first end 120a of the gun head 120, the outer peripheral surface of the area of ​​the gun head 120 near the first end 120a that is prone to damage can be protected, thereby more effectively reducing the possibility of damage to the gun head 120.

[0102] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, the gun head 120 in this embodiment may include a mounting part 121 and a gun head body 122.

[0103] The mounting portion 121 can be located at the first end 120a. The buffer layer 130 can be fitted onto the outer peripheral surface of the mounting portion 121. The gun head body 122 can be located at the second end 120b. The gun head body 122 is connected to the gun casing 110.

[0104] The longitudinal section of the mounting part 121 may be smaller than the longitudinal section of the gun head body 122. Both the longitudinal sections of the mounting part 121 and the gun head body 122 are perpendicular to the insertion direction X of the gun head 120.

[0105] In this embodiment, the buffer layer 130 can be connected to the gun head 120 via the mounting portion 121. By setting the longitudinal section of the mounting portion 121 to be smaller than the longitudinal section of the gun head body 122, the buffer layer 130 can be easily fitted onto the outside of the mounting portion 121, making it less likely that the outer peripheral surface of the buffer layer 130 will protrude from the outer peripheral surface of the gun head body 122. This reduces the possibility that the outer peripheral surface of the buffer layer 130 protruding from the outer peripheral surface of the gun head body 122 could affect the insertion of the gun head 120 into the vehicle.

[0106] See in some examples Figure 3 The buffer layer 130 may be an annular sleeve. The buffer layer 130 has a wall thickness so that when the charging gun 100 falls to the ground, the buffer layer 130 can absorb and buffer the impact force generated by the ground on the charging gun 100, thereby reducing the impact force on the gun head 120.

[0107] In some examples, the wall thickness of the buffer layer 130 can be greater than or equal to approximately 5 mm. For example, the wall thickness of the buffer layer 130 can be 4.5 mm, 4.8 mm, 5 mm, 6 mm, 7 mm, 8 mm, etc. When the wall thickness of the buffer layer 130 is less than approximately 5 mm, the buffer layer 130 has a poor buffering effect on the impact force of the ground, and the gun head 120 still has a significant risk of damage. Therefore, setting the wall thickness of the buffer layer 130 to be greater than or equal to approximately 5 mm can effectively solve the above-mentioned technical problem.

[0108] In some examples, the wall thickness of the buffer layer 130 can be within approximately 10 mm. For example, the wall thickness of the buffer layer can be 8 mm, 9 mm, 10 mm, 11 mm, etc. When the wall thickness of the buffer layer 130 is between approximately 5 mm and approximately 10 mm, the protection effect for the gun head 120 can be achieved, and the thickness of the buffer layer 130 will not be too thick, thus avoiding an increase in cost.

[0109] In some examples, the buffer layer 130 may extend along the insertion / removal direction of the nozzle 120. The length of the buffer layer 130 extending along the insertion / removal direction of the nozzle 120 may be less than or equal to half the size of the nozzle 120.

[0110] In some examples, the mounting portion 121 may be an annular recessed structure.

[0111] See also some of the possible implementation methods. Figures 4 to 7 As shown, the buffer layer 130 in this embodiment may include a buffer sleeve 131 and a buffer pad 132 connected together. The buffer sleeve 131 may be fitted over the outside of the mounting portion 121. Along the insertion direction of the gun head 120, the buffer pad 132 may cover at least a portion of the end face of the mounting portion 121 away from the gun head body 122.

[0112] In this embodiment, the buffer layer 130 can cover the outer peripheral surface of the mounting portion 121, and the buffer layer 130 can also cover at least a portion of the end face of the mounting portion 121 away from the gun housing 110. The buffer layer 130 can cover the entire outer surface of the mounting portion 121, so that the buffer layer 130 and the gun head 120 can have a larger contact area, thereby more effectively reducing the possibility of damage to the gun head 120 when the charging gun 100 is dropped.

[0113] Specifically, since the mounting part 121 is located at the first end 120a, and the outer peripheral surface of the mounting part 121 is a part of the gun head 120 that is easily damaged, the buffer sleeve 131 covers the outside of the mounting part 121 to protect the outer peripheral surface of the mounting part 121. When the charging gun 100 is dropped, the buffer sleeve 131 can protect the easily damaged outer peripheral surface of the gun head 120.

[0114] Since the buffer pad 132 is located at the end of the mounting portion 121 away from the gun housing 110, in other words, the buffer pad 132 is located on the end face of the gun head 120 away from the gun housing 110, and the buffer pad 132 is connected to the buffer sleeve 131, when the charging gun 100 falls and the end face of the gun head 120 away from the gun housing 110 faces the ground, the buffer pad 132 can contact the ground first. The buffer pad 132 can be located between the ground and the gun head 120 to absorb the impact force of the ground on the gun head 120, thereby protecting the end face of the gun head 120 away from the gun housing 110 from the impact of the ground and reducing the possibility of damage to the gun head 120.

[0115] In some examples, the buffer sleeve 131 and the buffer pad 132 can form an integral buffer layer 130 to facilitate the installation of the buffer layer 130. The buffer layer 130 has an opening 130a into which the mounting part 121 can be fitted. The opening 130a is disposed opposite to the buffer pad 132. When the buffer sleeve 131 is fitted onto the outer peripheral surface of the mounting part 121, the buffer pad 132 is located on the end face of the mounting part 121 away from the gun case 110.

[0116] In some examples, the charging head 120 may be provided with at least one terminal. At least a portion of the terminal is located in the mounting portion 121 of the charging head 120. The terminal can be electrically connected to the conductive wire core within the charging head 120 to be connected to the power supply component 210 within the charging pile 200 via the conductive wire core, so that when the charging head 120 is plugged into the vehicle's charging structure, the terminal can be electrically connected to the charging structure to charge the vehicle.

[0117] In some examples, the charging head 120 is provided with terminals (not shown in the figure). A corresponding area on the charging head 120 may be provided with a connector 120c. The terminals are located within the connector 120c. Correspondingly, the charging structure on the vehicle also has a connector corresponding to the terminals. The connector 120c allows insertion of the connector. The connector is electrically connected to the terminals, thereby electrically connecting the charging structure to the charging gun 100.

[0118] See in some examples Figure 4 and Figure 5 As shown, since the gun head 120 has a plug hole 120c, the buffer pad 132 can have a clearance hole 130c. The clearance hole 130c allows the plug hole 120c to be exposed, so as to facilitate the insertion of the connector of the vehicle's charging structure.

[0119] In other examples, see Figure 6 and Figure 7 As shown, since the gun head 120 is provided with a plug hole 120c, the buffer pad 132 can be provided with a through hole 130b that matches the plug hole 120c, so that the connector of the vehicle's charging structure can be inserted and connected to the terminal block.

[0120] See also some of the possible implementation methods. Figure 8 As shown, along the insertion direction X of the gun head 120, the buffer layer 130 of this embodiment can cover the end face of the gun head 120 away from the gun housing 110, and the buffer layer 130 can extend along the insertion direction X of the gun head 120.

[0121] In this embodiment, the buffer layer 130 can cover the end face of the gun head 120 away from the gun housing 110. Furthermore, since the buffer layer 130 can have a thickness along the insertion direction X of the gun head 120, when the charging gun 100 falls, the outer peripheral surface of the buffer layer 130 can contact the ground first to protect the area of ​​the gun head 120 near the first end 120a from damage.

[0122] It is easy to understand that, since the buffer layer 130 has a thickness along the insertion direction X of the charging gun 120, when the charging gun 100 is dropped and the outer peripheral surface of the mounting part 121 or the end face of the mounting part 121 away from the gun housing 110 faces the ground, the buffer layer 130 can protect the charging gun 120. The buffer layer 130 can absorb the impact force of the ground to reduce the impact force on the charging gun 120, thereby protecting the charging gun 120.

[0123] See also some of the possible implementation methods. Figure 8As shown, the longitudinal section of the buffer layer 130 in this embodiment matches the longitudinal section shape of the gun head 120. The longitudinal sections of the buffer layer 130 and the gun head 120 are perpendicular to the insertion direction X of the gun head 120.

[0124] In this embodiment, the outer contour of the buffer layer 130 can completely overlap with the outer contour of the gun head 120, so that when the gun head 120 is connected to the charging structure of the vehicle, the buffer layer 130 is less likely to cause obstruction and affect the insertion of the gun head 120.

[0125] Furthermore, since the gun head 120 is provided with a plug hole 120c for the connector of the vehicle charging structure to be inserted, the buffer layer 130 can be provided with a through hole 130b that matches the plug hole 120c, so that the connector of the charging structure can be plugged in when the gun head 120 is connected to the vehicle charging structure.

[0126] In some examples, the length of the buffer layer 130 extending along the insertion / removal direction of the nozzle 120 may be less than or equal to half the size of the nozzle 120.

[0127] See also some of the possible implementation methods. Figures 2 to 8 As shown, the outer peripheral surface of the buffer layer 130 can be flush with the outer peripheral surface of the gun head body 122.

[0128] In this embodiment, after the buffer layer 130 is fixed to the gun head 120, the outer peripheral surface of the buffer layer 130 may not exceed the outer peripheral surface of the gun head body 122, and the outer peripheral surface of the gun head body 122 may also not exceed the outer peripheral surface of the buffer layer 130, so that after the buffer layer 130 is installed, the part of the gun head 120 used for plugging into the vehicle charging structure can match the vehicle charging structure, thereby avoiding the buffer layer 130 from affecting the plugging of the gun head 120 into the vehicle charging structure.

[0129] In some examples, along the insertion direction X of the gun head 120, the orthographic projection of the outer contour of the buffer layer 130 coincides with the orthographic projection of the outer contour of the gun head body 122.

[0130] In some feasible embodiments, the buffer layer 130 and the gun head 120 of this application are integrally injection molded structures. Alternatively, the buffer layer 130 is fixedly connected to the gun head 120 by an adhesive.

[0131] In this embodiment, the buffer layer 130 can be integrally formed with the gun head 120 through injection molding or adhesive bonding. This integral structure improves the connection reliability between the buffer layer 130 and the gun head 120, preventing the buffer layer 130 from detaching due to repeated insertion and removal of the charging gun 100. Furthermore, it saves assembly steps, improves assembly efficiency, and reduces product costs.

[0132] This application embodiment can also provide a charging device 10. See also Figure 1 As shown, the charging device 10 may include the charging gun 100 and the charging pile 200 in any of the above embodiments.

[0133] The charging gun 100 may also include a charging cable 300. The charging cable 300 is connected to the gun housing 110 and to the charging station 200. The charging gun 100 can be connected to the charging station 200 via the charging cable 300.

[0134] In the charging device 10 of this application embodiment, since the charging gun 100 has a buffer layer 130 on the gun head 120, when the charging gun 100 falls to the ground, the buffer layer 130 can absorb at least part of the impact force from the ground on the gun head 120, thereby reducing the impact force on the gun head 120, protecting the gun head 120, reducing the possibility of damage to the gun head 120 affecting vehicle charging, and improving the service life and safety of the charging gun 100, thus improving the reliability of the charging device 10.
