These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] The AC charging gun is a key component of electric vehicle charging devices. It can be connected to both conventional power sources and photovoltaic circuits. Specifically, a photovoltaic circuit refers to a device composed of photovoltaic modules and photovoltaic inverters that can convert light energy into alternating current.

[0035] In related technologies, AC charging guns typically include a charging head and a control box. The control box primarily functions to connect or disconnect the power supply. The charging head is connected to the control box via a connecting cable, and the control box is connected to a photovoltaic circuit or a conventional power source via the connecting cable. The charging box includes a body, electrical components, and a cover. The electrical components are housed within the box, and the cover is bolted to the body to seal the box.

[0036] However, the lid is connected to the box by bolts, making disassembly and installation between the lid and the box cumbersome. It also requires separate sealing treatment at the bolts, resulting in high manufacturing costs and poor sealing performance.

[0037] The AC charging gun and charging device provided in this application embodiment have a connecting part circumferentially provided on the opening side of the box, forming a groove between the connecting part and the box. After the cover is installed, it abuts against the opening side of the box and the connecting part, sealing the opening side of the box and the groove. At the same time, the sealing element on the cover abuts against the box. The groove and the sealing element cooperate to form a double seal. The groove prevents rainwater from directly penetrating into the box, enhancing the waterproof sealing of the control box, effectively preventing external rainwater from seeping in, and ensuring the stable operation of the internal components of the control box.

[0038] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0039] This application provides an AC charging gun, referring to... Figure 1 , Figure 2 and Figure 3 The AC charging gun includes a charging head 100 and a control box 200.

[0040] The charging head 100 is used to connect to the vehicle.

[0041] The AC charging gun also includes a connecting cable 300. The charging head 100 is electrically connected to the control box 200 via the connecting cable 300. The control box 200 is connected to a conventional power source or a photovoltaic circuit via the connecting cable 300.

[0042] For example, the connecting cable 300 can be detachably connected to a conventional power supply or photovoltaic circuit via a quick-release connector to facilitate quick connection and use of the AC charging gun.

[0043] The control box 200 includes a box body 210, a cover 220, and a seal 230. A connecting part 211 is circumferentially provided on the opening side of the box body 210, and a groove 212 is formed between the connecting part 211 and the box body 210. The cover 220 is detachably connected to the box body 210 and abuts against the opening side of the box body 210 and the connecting part 211 respectively to close the opening side of the box body 210 and the groove 212. The seal 230 is provided on the cover 220 and abuts against the box body 210 to seal the gap between the cover 220 and the box body 210.

[0044] By providing a connecting part 211 circumferentially on the opening side of the box body 210, and forming a groove 212 between the connecting part 211 and the box body 210, the cover 220, after installation, abuts against the opening side of the box body 210 and the connecting part 211 respectively, sealing the opening side of the box body 210 and the groove 212. At the same time, the sealing element 230 on the cover 220 abuts against the box body 210. The groove 212 and the sealing element 230 cooperate to form a double seal. The groove 212 prevents rainwater from directly penetrating into the box body 210, enhancing the waterproof sealing of the control box 200, effectively preventing external rainwater from seeping in, and ensuring the stable operation of the internal components of the control box 200.

[0045] The connecting part 211 is disposed on the outer side wall of the box body 210 and is arranged circumferentially along the opening side of the box body 210. The top of the connecting part 211 is located on the same plane as the top of the box body 210. A groove 212 is formed between the top of the connecting part 211 and the side wall of the box body 210, and the bottom of the connecting part 211 is connected to the box body 210.

[0046] For example, the connecting part 211 is integrally formed with the box body 210.

[0047] In one possible implementation, refer to Figure 2 Multiple reinforcing ribs 215 are provided between the connecting part 211 and the box body 210, and the reinforcing ribs 215 are located in the groove 212.

[0048] Multiple reinforcing ribs 215 are provided between the connecting part 211 and the box body 210, and the reinforcing ribs 215 are located in the groove 212, which improves the structural strength and stability of the control box 200, enabling it to better resist external physical impacts and vibrations, and ensure the stable operation of internal components. In addition, the reinforcing ribs 215 divide the groove 212 into multiple chambers, so that the reinforcing ribs 215 form a more complex sealing path in the groove 212, which enhances the sealing effect between the cover 220 and the box body 210, further improves the waterproof sealing performance, effectively prevents moisture from seeping into the box body 210 from the gaps, and provides more reliable protection for the electronic components inside the control box 200.

[0049] In one possible implementation, refer to Figure 2 and Figure 3 The cover 220 is provided with multiple connectors 224, which are inserted into the groove 212 and detachably connected to the connecting part 211. The cover 220 and the box 210 are detachably connected to facilitate the installation and maintenance of the control box 200 and improve the ease of use.

[0050] For example, the connector 224 can be a snap-fit, and the connecting part 211 is provided with a slot. The snap-fit ​​is inserted into the groove 212 and engages with the slot. The snap-fit ​​has a certain degree of elasticity to facilitate insertion into the corresponding slot.

[0051] Furthermore, the reinforcing ribs 215 can separate the various clips, preventing them from interfering with each other.

[0052] For example, to prevent water from accumulating in the trench 212, the bottom of the trench 212 has a drain outlet.

[0053] For example, there are eight connectors 224, which are symmetrically arranged on both sides of the cover 220 along its length.

[0054] For example, limiting blocks 225 are provided on both sides of the cover 220 in the width direction. The limiting blocks 225 are inserted into the groove 212, thereby restricting the connection between the two sides of the cover 220 in the width direction and the cover 220. In addition, the limiting blocks 225 can also play a positioning role to facilitate the installation of the cover 220 on the box 210.

[0055] For example, the positioning rib also divides the groove 212 to form a limiting groove that cooperates with the limiting block 225. The limiting block 225 is inserted into the limiting groove to further limit the position of the limiting block 225.

[0056] For example, the connector 224 and the cover 220 are integrally formed to facilitate the manufacturing of the cover 220.

[0057] For example, the limiting block 225 is also integrally formed with the cover 220 to facilitate the manufacturing of the cover 220.

[0058] For example, the cover 220 can be made of plastic or metal.

[0059] In other embodiments, connecting portions 211 can also be provided on both sides of the cover 220 in the width direction.

[0060] In one possible implementation, refer to Figure 4 The cover 220 is provided with a sealing part 221 in the circumferential direction. The sealing part 221 extends into the box body 210, and the sealing element 230 is connected to the sealing part 221.

[0061] The sealing part 221 is circumferentially disposed on the side of the cover 220 near the box 210. When the cover 220 is placed on the box 210, the sealing part 221 is inserted into the box 210 and abuts against the inner wall of the box 210. The sealing element 230 is sleeved on the sealing part 221 to seal the gap between the inner wall of the cover 220 and the sealing part 221, so as to further improve the sealing effect.

[0062] When the cover 220 is placed on the box 210, the sealing part 221 can be inserted into the box 210 and tightly abut against the inner wall of the box 210, forming a sealing barrier through this tight fit. Simultaneously, the sealing element 230 is fitted onto the sealing part 221, further filling and sealing the tiny gap between the inner wall of the cover 220 and the sealing part 221, thereby further improving the sealing effect. This better prevents external moisture, dust, and other foreign objects from intruding through the gap between the cover 220 and the box 210, improving the waterproof and dustproof performance of the control box 200, ensuring the stable operation of internal components in harsh environments, extending the service life of the control box 200, and guaranteeing the overall reliability of the AC charging gun.

[0063] In one possible implementation, refer to Figure 3 and Figure 4 The sealing part 221 is provided with a sealing groove 222, and the sealing element 230 is disposed in the sealing groove 222 and abuts against the inner side wall of the box body 210.

[0064] The sealing groove 222 is circumferentially arranged on the side of the sealing part 221 near the inner wall of the box body 210. When the sealing element 230 is sleeved on the sealing groove 222, it protrudes from the sealing groove 222 to facilitate contact with the inner wall of the box body 210.

[0065] The sealing part 221 is closer to the center of the cover 220 than the connector 224, so that the sealing part 221 is inserted into the cover 220 and the connector 224 is inserted into the groove 212.

[0066] An exemplary sealing portion 221 is integrally formed with the cover 220 to facilitate the manufacture of the cover 220.

[0067] For example, seal 230 can be a rubber sealing ring.

[0068] In one possible implementation, refer to Figure 2 and Figure 4 The sealing part 221 is provided with multiple connecting grooves 223, and the inner wall of the box body 210 is provided with multiple connecting blocks 213, which are snapped into the corresponding connecting grooves 223.

[0069] For example, the sealing part 221 has multiple extension blocks extending towards the bottom of the box body 210. Each extension block has a connecting groove 223, and the connecting block 213 is a snap-fit. When the cover 220 is placed on the box body 210, the connecting block 213 engages with the connecting groove 223, thus fixing the cover 220 to the inside of the box body 210. This further enhances the stability of the connection between the cover 220 and the box body 210.

[0070] For example, the extension blocks are symmetrically arranged on both sides of the cover 220 in the width direction, and the corresponding connecting block 213 is arranged on the inner side wall of the box 210 in the width direction. Thus, the connection between the cover 220 and the box 210 in the width direction is realized through the snap-fit ​​between the connecting block 213 and the connecting groove 223.

[0071] In one possible implementation, refer to Figure 2 A limiting part 214 is provided inside the box body 210, and the limiting part 214 abuts against the side of the sealing part 221 near the middle of the box body 210.

[0072] For example, multiple limiting portions 214 are provided, and the multiple limiting portions 214 are located on the inner sidewall of the box body 210 in the width direction. The limiting portions 214 abut against the side of the sealing portion 221 near the center of the box body 210. During the process of the cover 220 covering the box body 210, the limiting portions 214 abut against the inner sidewall of the sealing portion 221 to drive the connecting groove 223 on the sealing portion 221 to engage with the connecting block 213 on the inner wall of the box body 210, thereby improving the stability of the connection.

[0073] For example, the limiting portion 214 is an L-shaped block. A portion of the limiting portion 214 extends into the inside of the sealing portion 221, such that the groove of the limiting portion 214 abuts against the sealing portion 221.

[0074] For example, the connection end between the control box 200 and the connecting cable 300 has a rubber sleeve and a sealing ring, which effectively prevents external moisture, dust, and other foreign objects from entering from the connection point between the cable and the control box 200. The rubber sleeve tightly wraps around the connecting cable 300, forming a preliminary seal and preventing foreign objects from entering along the cable surface. The sealing ring is sandwiched between the control box 200 and the rubber sleeve, further filling any possible tiny gaps and enhancing the sealing effect, maintaining good sealing performance even under vibration or slight displacement.

[0075] In one possible implementation, refer to Figure 2 and Figure 4 The cover 220 is provided with a display element 240, which is used to display the charging status of the charging head 100. The cover 220 is provided with a protective layer 250, which covers the display element 240 to seal the gap between the display element 240 and the cover 220.

[0076] A protective layer 250 is added to the display component 240, which effectively protects the display component 240 from damage caused by the external environment. At the same time, the protective layer 250 covers the gap between the display component 240 and the cover 220, which enhances the sealing of the display component 240 and further improves the reliability of the control box 200.

[0077] In one possible implementation, the display 240 includes a plurality of status lights 241 and a charging display bar 242. The plurality of status lights 241 are used to display the status of the charging head 100, and the charging display bar 242 is used to display the charging completion status of the vehicle.

[0078] For example, a display circuit board 243 is provided on the side of the cover 220 near the box 210. The status light 241 and the charging display bar 242 are electrically connected to the display circuit board 243, and the display circuit board 243 is electrically connected to the internal components of the box 210.

[0079] For example, status lights 241 include a WIFI indicator, a LOAR indicator, a NORMAL indicator, and an ALARM indicator. The WIFI indicator displays the WIFI connection status between the control box 200 and the vehicle or related equipment. The LOAR indicator displays the communication status between the control box 200 and the antenna of the vehicle or related equipment. The NORMAL indicator displays normal operation of the control box 200. The ALARM indicator displays an abnormal state of the control box 200.

[0080] For example, the charging display bar 242 is a strip-shaped display structure composed of multiple indicator lights, which can display the charging completion status of the vehicle according to its charging status. During charging, the charging display bar 242 gradually changes color. When the AC charging station is idle, the charging display bar 242 illuminates green.

[0081] In one possible implementation, a control button 260 is provided on the cover 220. The control button 260 is used to control the power supply of the charging head 100. The side wall of the control button 260 abuts against the protective layer 250.

[0082] For example, the control button 260 is a power button, which can control the power supply to the charging head 100. The protective layer 250 abuts against the side wall of the control button 260 to provide a waterproof effect.

[0083] For example, the protective layer 250 may be a plastic film layer. The protective layer 250 is adhered to the surface of the cover 220.

[0084] For example, a sealing layer is fixed to the bottom of the control button 260. The area of ​​the sealing layer is larger than the surface area of ​​the control button 260. The protective layer 250 is adhered to the sealing layer, thereby improving the sealing effect and preventing rainwater from seeping in.

[0085] Reference Figure 2 , Figure 3 and Figure 5 The housing 210 contains a power circuit board 270 and a control circuit board 280. The control circuit board 280 is located at the bottom of the housing 210, and the power circuit board 270 is located above the control circuit board 280, near the end of the housing 210 that connects to the power source. There is a gap between the control circuit board 280 and the bottom wall of the housing 210. Multiple connecting posts are provided inside the housing 210, and the control circuit board 280 is mounted on these posts with bolts. Similarly, there is a gap between the power circuit board 270 and the control circuit board 280, and they are also connected to the connecting posts within the housing 210 with bolts. The power circuit board 270 and the control circuit board 280 are electrically connected; the power circuit board 270 is electrically connected to the charging device body, and the control circuit board 280 is electrically connected to the charging head 100.

[0086] For example, multiple current transformers 281 are electrically connected to the control circuit board 280. By detecting changes in current, when an abnormal situation such as overload or short circuit occurs, the current transformers 281 will transmit a signal to the control circuit to trigger corresponding protection measures, such as cutting off the charging circuit, to protect the charging gun, vehicle and charging system from damage and ensure the safety of the charging process.

[0087] For example, multiple relays 282 are also electrically connected to the control circuit board 280. Each relay 282 acts as an electrical control device, capable of connecting or disconnecting the charging circuit according to a control signal. When the AC charging gun begins charging, the control box 200 sends a signal to close the relays 282, establishing a charging circuit. When charging is complete or an abnormal situation occurs, the control box 200 controls the relays 282 to disconnect, cutting off the charging current and achieving automated control of the charging process.

[0088] In addition, relay 282 can also work with current transformer 281. When current transformer 281 detects an overload or short circuit current exceeding the set value, the control circuit will quickly disconnect relay 282 to stop charging, preventing damage to the charging gun, vehicle battery or other charging equipment due to excessive current, or even causing a safety accident, thus protecting the entire charging system.

[0089] The control circuit board 280 is also electrically connected to a Wi-Fi module and a LoRa antenna module.

[0090] This application also provides a charging device, including a charging device body and an AC charging gun connected to the charging device body.

[0091] The AC charging gun in this embodiment has the same structure as the AC charging gun provided in any of the above embodiments and can bring the same or similar technical effects. Further details will not be elaborated here; please refer to the descriptions of the above embodiments for specific information. The charging device can be used to connect to a conventional power source or to a photovoltaic system.

[0092] The charging device provided in this application embodiment has a connecting part 211 circumferentially provided on the opening side of the box 210, and a groove 212 is formed between the connecting part 211 and the box 210. After the cover 220 is installed, it abuts against the opening side of the box 210 and the connecting part 211 respectively, sealing the opening side of the box 210 and the groove 212. At the same time, the sealing element 230 on the cover 220 abuts against the box 210. The groove 212 and the sealing element 230 cooperate to form a double seal. The groove 212 prevents rainwater from directly penetrating into the box 210, enhances the waterproof sealing of the control box 200, effectively prevents external rainwater from seeping in, and ensures the stable operation of the internal components of the control box 200.

[0093] Finally, it should be noted that other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
