Description

Technical Field

[0001] This application belongs to the technical field of charging equipment, specifically relating to an AC charging gun. Background Technology

[0002] With the popularization of new energy electric vehicles, AC fast charging cabinets have developed rapidly. Charging guns are an important part of charging cabinets, and their long-term safety and stability have become a focus of attention.

[0003] Currently, charging guns include a gun body and a locking arm located at the front end of the gun body. The locking arm has a rotating shaft rotatably connected to the gun body, and the locking arm can rotate around the rotating shaft so that the locking arm has a locking position where the front end can engage with the charging vehicle and an unlocking position where the front end can disengage from the charging vehicle. However, in order to facilitate the installation of the locking arm, the locking arm is usually directly exposed to the outside of the gun body. This allows rainwater to enter the inside of the gun body through the gap between the locking arm and the gun body, thus affecting the safety of the charging gun. At the same time, because the locking arm is directly exposed to the outside of the gun body, it is prone to bumps and knocks, which can easily damage the locking arm and affect the connection stability between the charging gun and the charging vehicle. Utility Model Content

[0004] This application provides an AC charging gun to increase the safety of the charging gun, extend the service life of the locking arm, and ensure the connection stability between the charging gun and the charging vehicle.

[0005] The technical solution adopted in this application is as follows:

[0006] An AC charging gun includes a gun body, a locking arm, and a cover plate. The gun body has a front end and a rear end opposite to the front end. The top of the front end of the gun body has a mounting position. The locking arm is disposed at the mounting position. The mounting position has connecting portions located on opposite sides of the locking arm. The locking arm has a rotating shaft extending into the connecting portion. The cover plate is disposed on the gun body and covers the locking arm.

[0007] By adopting the above technical solution, since the cover plate in this application is located on the gun body and covers the locking arm, on the one hand, the cover plate can block the gap between the locking arm and the gun body to prevent rainwater from entering the gun body through the gap between the locking arm and the gun body, thereby extending the service life of the charging gun and increasing the safety of the charging gun. On the other hand, the cover plate can also protect the locking arm to prevent the locking arm from being easily bumped and damaged, thereby extending the service life of the locking arm and ensuring the connection stability between the charging gun and the charging vehicle, so as to ensure the stability when charging the charging vehicle.

[0008] Optionally, the gun body has locking portions located on both sides of the locking arm, and the cover plate is provided with a mating portion that engages with the locking portion and the connecting portion, so as to fix the cover plate by engaging with the locking portion and the connecting portion.

[0009] By adopting the above technical solution, since the mating part can engage with the locking part and the connecting part, the cover plate can be fixed by engaging with the locking part and the connecting part, thereby reducing the difficulty of fixing the cover plate and improving the assembly efficiency of the cover plate. At the same time, it can also increase the number of connection points between the cover plate and the gun body, thereby increasing the connection stability between the cover plate and the gun body. In addition, it can also give the connecting part a new function, thereby increasing the flexibility of the connecting part and reducing the size of the gun body, so as to facilitate the user's operation of the charging gun.

[0010] Optionally, the front end of the gun body has a conductive module, the cover plate has a limiting wall located behind the conductive module, the conductive module is provided with a fastener connected to the locking part, and the fastener passes through the limiting wall.

[0011] By adopting the above technical solution, since the conductive module is provided with fasteners connected to the locking part, and the fasteners pass through the limiting wall, the cover plate can be further fixed by the fasteners that fix the conductive module, thereby further increasing the stability of the cover plate. At the same time, the fasteners connected to the locking part can also give the locking part a new function, thereby increasing the flexibility of the locking part, further reducing the size of the gun body, and thus further achieving the effect of facilitating the user to operate the charging gun.

[0012] Optionally, the gun body is provided with an unlock button located on the rear side of the cover plate, and the gun body is provided with an elastic element acting on the rear end of the locking arm. The unlock button can move relative to the gun body and act on the rear end of the locking arm, and the unlock button and the elastic element act on opposite sides of the locking arm respectively.

[0013] By adopting the above technical solution, when unlocking the locking arm, pressing the unlock button applies pressure to the rear end of the locking arm, causing the rear end of the locking arm to overcome the elastic force of the elastic element and move downwards. At the same time, the front end of the locking arm moves upwards, moving the locking arm to the unlock position to complete the unlocking with the charging vehicle. After releasing the unlock button, the elastic element gradually returns to its original deformation, causing the rear end of the locking arm to move upwards under the action of the elastic element. Simultaneously, the rear end of the locking arm pushes the unlock button upwards to reset the unlock button. In this process, only the unlock button needs to be pressed; no force needs to be applied to reset the unlock button, thus facilitating user operation of the locking arm and improving the user experience.

[0014] Optionally, the gun body has a mounting cavity, at least a portion of the unlock button is located in the mounting cavity, and the gun body is provided with a drain hole communicating with the mounting cavity, the opening of the drain hole being located on the outer peripheral surface of the gun body.

[0015] By adopting the above technical solution, since at least part of the unlock button is located in the mounting cavity, the stability of the unlock button is increased. Furthermore, the gun body is provided with a drainage hole that communicates with the mounting cavity. The opening of the drainage hole is located on the outer circumferential surface of the gun body, so that rainwater entering the mounting cavity through the gap between the unlock button and the wall of the mounting cavity can flow to the outside of the gun body under the action of the drainage hole, thereby draining the mounting cavity and further increasing the safety of the charging gun.

[0016] Optionally, the elastic element is a spring, and the locking arm and / or the gun body are provided with a limiting protrusion, with the spring sleeved on the limiting protrusion.

[0017] By adopting the above technical solution, since the spring is sleeved on the limiting protrusion, the limiting protrusion can limit the spring, thereby increasing the stability of the spring and ensuring the elastic driving effect of the spring on the unlocking button. At the same time, it ensures the stability of the engagement between the charging gun and the charging vehicle, thereby increasing the connection stability between the charging gun and the charging vehicle.

[0018] Optionally, the gun body has a control module electrically connected to the conductive module. The control module is electrically connected to a micro switch. The locking arm can trigger the micro switch. The control module has an indicator light. A light guide column is provided inside the gun body corresponding to the indicator light. One end of the light guide column passes through the locking arm and extends into or out of the cover plate.

[0019] By adopting the above technical solution, since the indicator light on the gun body is equipped with a light guide column, one end of the light guide column passes through the locking arm and extends into or out of the cover plate, the light emitted by the indicator light can be transmitted to the outside of the cover plate through the light guide column to remind the user of the status of the charging gun, thereby improving the prompting effect to the user and further improving the user experience.

[0020] Optionally, the gun body has a partition rib inside, the light guide post passes through the partition rib, and the outside of the light guide post is fitted with a sealing ring that is sealed and connected to the partition rib.

[0021] And / or, the gun body is provided with a sliding groove inside, the extension direction of the sliding groove is parallel to the direction of the front opening of the gun body, and both ends of the control module extend into the sliding groove.

[0022] By adopting the above technical solution, since the light guide post is fitted with a sealing ring that is sealed to the partition rib, the sealing ring can seal the gap between the partition rib and the light guide post, thereby further preventing rainwater from entering the gun body, thus further improving the waterproof performance of the charging gun, further extending the service life of the charging gun, and further improving the safety of the charging gun.

[0023] Since the extension direction of the slide is parallel to the direction of the opening at the front end of the gun body, on the one hand, when installing the control module, the control module can be installed into the inside of the gun body through the opening at the front end of the gun body, so as to reduce the assembly difficulty of the control module. On the other hand, the groove wall can limit the charging module to increase the installation stability of the charging module and the gun body.

[0024] Optionally, the gun body has a tail cap at the rear end and a cable sleeve passing through the tail cap, and the inner side of the cable sleeve has a stop rib that cooperates with the stop of the tail cap.

[0025] By adopting the above technical solution, since the inner side of the cable sleeve has a stop rib that cooperates with the end cover stop, the end cover can stop the cable sleeve in the outward direction to prevent the cable sleeve from separating from the end cover, thereby increasing the connection stability between the cable sleeve and the end cover, and thus ensuring the connection stability between the cable and the control module.

[0026] Optionally, an extension seat is provided on the inner side of the tail cover, and the extension seat is provided with a clamping plate for clamping the cable. The clamping plate is located on the inner side of the cable sleeve so that the clamping plate can cooperate with the stop of the cable sleeve.

[0027] By adopting the above technical solution, since the clamping plate is located inside the cable sleeve and is located on the extension seat, the clamping plate can stop the cable sleeve in the inward direction to prevent the cable sleeve from moving into the gun body, thereby further increasing the stability of the cable sleeve and further ensuring the connection stability between the cable and the control module.

[0028] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0029] 1. The charging gun in this application includes a gun body, a locking arm, and a cover plate. The gun body has a front end and a rear end opposite to the front end.

The mounting position has connecting parts located on opposite sides of the locking arm. The locking arm has a rotating shaft extending into the connecting parts. The cover plate is located on the gun body and covers the locking arm. On the one hand, the cover plate can block the gap between the locking arm and the gun body to prevent rainwater from entering the gun body through the gap between the locking arm and the gun body, thereby extending the service life of the charging gun and increasing its safety. On the other hand, the cover plate can also protect the locking arm to prevent it from being easily bumped and damaged, thereby extending the service life of the locking arm and ensuring the connection stability between the charging gun and the charging vehicle, so as to ensure the stability when charging the vehicle.

[0030] 2. The gun body in this application has locking parts located on both sides of the locking arm, and the cover plate is provided with a mating part that engages with the locking part and the connecting part. The mating part is used to fix the cover plate by engaging with the locking part and the connecting part, thereby reducing the difficulty of fixing the cover plate and improving the assembly efficiency of the cover plate.

[0046] Reference Figures 1 to 6 An AC charging gun is disclosed, which includes a gun body 1, a locking arm 2 and a cover plate 3. The gun body 1 has a front end and a rear end opposite to the front end. The top of the front end of the gun body 1 has a mounting position 11. The locking arm 2 is located at the mounting position 11. The mounting position 11 is provided with connecting parts 111 located on opposite sides of the locking arm 2. The locking arm 2 has a rotating shaft 21 that extends into the connecting part 111. The cover plate 3 is located on the gun body 1 and covers the locking arm 2.

[0047] Since the cover plate 3 in this application is located on the gun body 1 and covers the locking arm 2, on the one hand, the cover plate 3 can block the gap between the locking arm 2 and the gun body 1 to prevent rainwater from entering the gun body 1 through the gap between the locking arm 2 and the gun body 1, thereby extending the service life of the charging gun and increasing the safety of the charging gun. On the other hand, the cover plate 3 can also protect the locking arm 2 to prevent the locking arm 2 from being easily bumped and damaged, thereby extending the service life of the locking arm 2 and ensuring the connection stability between the charging gun and the charging vehicle, so as to ensure the stability when charging the charging vehicle.

[0048] This application does not specify the connection method between the cover plate 3 and the gun body 1. Preferably, refer to... Figure 2 and Figure 4The gun body 1 has a locking part 112 located on both sides of the locking arm 2. The cover plate 3 is provided with a mating part 31 that engages with the locking part 112 and the connecting part 111, so as to fix the cover plate 3 by engaging with the locking part 112 and the connecting part 111.

[0049] Since the mating part 31 can engage with the locking part 112 and the connecting part 111, the cover plate 3 can be fixed by engaging with the locking part 112 and the connecting part 111, thereby reducing the difficulty of fixing the cover plate 3 and improving the assembly efficiency of the cover plate 3. At the same time, it can also increase the number of connection points between the cover plate 3 and the gun body 1, thereby increasing the connection stability between the cover plate 3 and the gun body 1. In addition, it can also give the connecting part 111 a new function, thereby increasing the flexibility of the connecting part 111 and reducing the size of the gun body 1, so as to facilitate the user's operation of the charging gun.

[0050] This application does not impose specific limitations on the structure of the connecting part 111, the locking part 112, and the mating part 31. Preferably, all three are block structures to ensure the connection stability between the cover plate 3 and the gun body 1. In other embodiments, the three can also be other structures as long as they can achieve the snap-fit ​​engagement between the mating part 31 and the connecting part 111 and the locking part 112.

[0051] Furthermore, refer to Figures 1 to 3 The front end of the gun body 1 has a conductive module 12, and the cover plate 3 has a limiting wall 32 located behind the conductive module 12. The conductive module 12 is provided with a fastener connected to the locking part 112, and the fastener passes through the limiting wall 32.

[0052] It is understood that the front end of the gun body 1 has an opening, and the conductive module 12 is installed at the opening at the front end of the gun body 1. The conductive module 12 includes an insulator and a charging terminal disposed inside the insulator, and fasteners are disposed on the insulator.

[0053] Since the conductive module 12 is provided with fasteners connected to the locking part 112, and the fasteners pass through the limiting wall 32, the cover plate 3 can be further fixed by using the fasteners that fix the conductive module 12, so as to further increase the stability of the cover plate 3. At the same time, the fasteners connected to the locking part 112 can also give the locking part 112 new functions, so as to increase the flexibility of the locking part 112, further reduce the size of the gun body 1, and further achieve the effect of facilitating the user to operate the charging gun.

[0054] This application does not specifically limit the structure of the fastener. Preferably, the fastener is a screw to facilitate the fixing of the charging module. In other embodiments, the fastener can also be a snap-fit ​​post or other structures that can fix the charging module.

[0055] In other embodiments, the cover plate 3 may also be connected to the gun body 1 by screws or other fixing structures.

[0056] This application does not specify a particular unlocking method for the locking arm 2; preferably, refer to... Figure 1 , Figure 2 , Figure 3 and Figure 6 The gun body 1 is provided with an unlock button 4 located on the rear side of the cover plate 3. The gun body 1 is provided with an elastic element 5 that acts on the rear end of the locking arm 2. The unlock button 4 can move relative to the gun body 1 and act on the rear end of the locking arm 2. The unlock button 4 and the elastic element 5 act on opposite sides of the locking arm 2 respectively.

[0057] It is understandable that the locking arm 2 has a locking position where the front end engages with the charging vehicle and an unlocking position where the front end disengages from the charging vehicle. In the unlocking position, the elastic element 5 deforms and applies an elastic force to the locking arm 2 toward the locking position.

[0058] When unlocking the locking arm 2, press the unlock button 4 to apply pressure to the rear end of the locking arm 2. This causes the rear end of the locking arm 2 to overcome the elastic force of the elastic element 5 and move downwards, while the front end of the locking arm 2 moves upwards, moving the locking arm 2 to the unlock position to complete the unlocking with the charging vehicle. After releasing the unlock button 4, the elastic element 5 gradually returns to its original shape, causing the rear end of the locking arm 2 to move upwards under the action of the elastic element 5. At the same time, the rear end of the locking arm 2 pushes the unlock button 4 upwards to reset the unlock button 4. During this process, only the unlock button 4 needs to be pressed; no force needs to be applied to reset the unlock button 4, making it easier for the user to operate the locking arm 2 and improving the user experience.

[0059] Furthermore, refer to Figure 3 The gun body 1 has a mounting cavity 13, and at least part of the unlock button 4 is located in the mounting cavity 13, thereby increasing the stability of the unlock button 4. The gun body 1 is provided with a drain hole 131 communicating with the mounting cavity 13. The opening of the drain hole 131 is located on the outer peripheral surface of the gun body 1, so that rainwater entering the mounting cavity 13 through the gap between the unlock button 4 and the cavity wall of the mounting cavity 13 can flow to the outside of the gun body 1 under the action of the drain hole 131, thereby draining the mounting cavity 13 and further increasing the safety of the charging gun.

[0060] This application does not specifically limit the structure of the elastic element 5. Preferably, the elastic element 5 is a spring. The locking arm 2 and / or the gun body 1 are provided with a limiting protrusion 22. The spring is sleeved on the limiting protrusion 22, thereby limiting the spring and increasing the stability of the spring. This ensures the elastic driving effect of the spring on the unlocking button 4, and at the same time ensures the stability of the engagement between the charging gun and the charging vehicle, thereby increasing the connection stability between the charging gun and the charging vehicle.

[0061] The better one is to refer to Figure 3 Both the locking arm 2 and the gun body 1 are provided with limit protrusions 22 to further increase the stability of the spring.

[0062] In other implementation examples, the elastic element 5 can also be an elastic sheet, an elastic column, or other structures that can apply an elastic force to the locking arm 2.

[0063] In other embodiments, the locking arm 2 has an operating part exposed at the rear end of the cover plate 3, so that the user can unlock the locking arm 2 by operating the operating part.

[0064] In a preferred embodiment, refer to Figure 3 and Figure 5 The gun body 1 has a control module 6 that is electrically connected to the conductive module 12. The control module 6 is electrically connected to a micro switch 7. The locking arm 2 can trigger the micro switch 7. The control module 6 has an indicator light. The gun body 1 has a light guide column 8 corresponding to the indicator light. One end of the light guide column 8 passes through the locking arm 2 and extends into or out of the cover plate 3, so that the light emitted by the indicator light can be transmitted to the outside of the cover plate 3 through the light guide column 8 to remind the user of the status of the charging gun, thereby improving the prompting effect to the user and further improving the user experience.

[0065] It is understandable that the cover plate 3 is provided with a through hole corresponding to the light guide post 8, and the end of the light guide post 8 away from the indicator light extends into or out of the through hole so that the light emitted by the indicator light can be displayed through the through hole.

[0066] The better one is to refer to Figure 5 The control module 6 includes a control circuit board 61 and a charging / discharging unit 62 electrically connected to the control circuit board 61. The control circuit board 61 has the ability to control and process signals and can control the charging / discharging unit 62 to charge or discharge.

[0067] Furthermore, refer to Figure 3 and Figure 6The gun body 1 has a partition rib 14 inside, and the light guide post 8 passes through the partition rib 14. The light guide post 8 is fitted with a sealing ring 81 that is sealed and connected to the partition rib 14. The sealing ring 81 can seal the gap between the partition rib 14 and the light guide post 8, so as to further prevent rainwater from entering the gun body 1, thereby further improving the waterproof performance of the charging gun, extending the service life of the charging gun, and further improving the safety of the charging gun.

[0068] Furthermore, refer to Figure 6 The gun body 1 has a sliding groove 15 inside. The extension direction of the sliding groove 15 is parallel to the direction of the front opening of the gun body 1. The two ends of the control module 6 extend into the sliding groove 15. On the one hand, when installing the control module 6, the control module 6 can be installed into the gun body 1 through the front opening of the gun body 1, so as to reduce the assembly difficulty of the control module 6. On the other hand, the groove wall of the sliding groove 15 can support and limit the charging module, so as to increase the installation stability of the charging module and the gun body 1.

[0069] In a preferred embodiment, refer to Figures 1 to 3 The gun body 1 has a tail cover 16 and a cable sleeve 161 passing through the tail cover 16. The inner side of the cable sleeve 161 has a stop rib 162 that cooperates with the stop of the tail cover 16, so that the tail cover 16 can stop the cable sleeve 161 in the outward direction to prevent the cable sleeve 161 from separating from the tail cover 16, thereby increasing the connection stability between the cable sleeve 161 and the tail cover 16, and thus ensuring the connection stability between the cable and the control module 6.

[0070] Preferably, the tail cover 16 is fixedly connected to the gun body 1 by screws to increase the connection stability between the tail cover 16 and the gun body 1, and at the same time to facilitate the assembly of the tail cover 16.

[0071] Furthermore, refer to Figures 1 to 3 An extension seat 163 is provided on the inner side of the tail cover 16. The extension seat 163 is provided with a clamping plate 164 for clamping the cable. The clamping plate 164 is located inside the cable sleeve 161, thereby enabling the clamping plate 164 to stop the cable sleeve 161 in the inward direction, so as to prevent the cable sleeve 161 from moving into the gun body 1, thereby further increasing the stability of the cable sleeve 161, so as to further ensure the connection stability between the cable and the control module 6.

[0072] Furthermore, a sealing gasket is provided between the conductive module 12 and the tail cap 16 and the gun body 1 to increase the sealing between the conductive module 12 and the gun body 1 and the tail cap 16 and the gun body 1.

[0073] In a preferred embodiment, refer to Figure 1The charging gun also includes a dust cover 9 that can be fitted over the conductive module 12. The dust cover 9 has an anti-loss rope that is fixedly connected to the tail cover 16, so that the dust cover 9 can be connected to the tail cover 16 through the anti-loss rope to avoid the possibility of the dust cover 9 being lost, thereby improving the user experience. At the same time, the dust cover 9 can also protect the charging module from dust and increase the cleanliness of the charging module.
