[0070] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0071] It is easy to understand that according to the technical solution of the present invention, a variety of structural modes and implementation modes can be replaced with each other by those skilled in the art without changing the essential spirit of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the invention.

[0072] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to the structure shown in the drawings. They are relative concepts and may vary depending on the location and usage of the device. Therefore, these or other directional terms should not be interpreted as restrictive.

[0073] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the integrated charging gun 10 includes a gun head assembly 1, a gun body 2, and a gun tail assembly 3. The gun head assembly 1 is installed from the head of the gun body 2 to the inside of the gun body 2, and the gun tail assembly 3 is sealed and connected to the tail of the gun body 2. The gun body 2 is an integrally formed shell.

[0074] The gun head assembly 1 includes a gun head housing 11, a micro switch 12, a hook button unit 13, a mounting bracket 14, a pin assembly 15, a temperature detection unit 16 and a PCBA module 17. The gun head housing 11 is installed on the head of the gun body 2, the micro switch 12 is installed on the top surface of the gun head housing 11, the hook button unit 13 is installed on the mounting bracket 14 and is located above the micro switch 12, the mounting bracket 14 is connected to the gun head housing 11, and the pin assembly 15, the temperature detection unit 16 and the PCBA module 17 are all installed on the mounting bracket 14.

[0075] A button hole 21 is defined in the gun body 2 . After the gun head assembly 1 is entirely installed in the gun body 2 , the hook button unit 13 at least partially extends out of the button hole 21 .

[0076] Specifically, Figure 1 As shown, the integrated charging gun 10 includes a gun head assembly 1, a gun body 2, and a gun tail assembly 3. The gun head assembly 1 is installed at the head of the gun body 2, with part of the gun head assembly 1 installed inside the gun body 2 and part of the gun head assembly 1 located outside the head of the gun body 2 and sealed to the head of the gun body 2.

[0077] like Figure 1 As shown, the gun body 2 is an integrally formed hollow shell structure, and the internal cavity of the gun body 2 is used to install most of the structures of the gun head assembly 1 and the gun tail assembly 3. Figure 2 As shown, a button hole 21 is provided on the top surface of the gun body 2 , and part of the structure of the hook button unit 13 of the gun head assembly 1 extends out of the button hole 21 , which is convenient for pressing the hook button unit 13 from the outside, thereby controlling the opening of the integrated charging gun 10 .

[0078] like Figure 1 As shown, the tail assembly 3 is installed at the tail of the gun body 2 , part of the tail assembly 3 is installed inside the gun body 2 , and another part is located outside the tail of the gun body 2 for sealing the tail of the gun body 2 .

[0079] In this embodiment, since the gun body 2 is an integrally formed shell structure, the hook button unit 13 is installed into the gun body 2 together with the gun head assembly 1 as a whole, which makes installation more convenient and makes the overall appearance of the charging gun unified and simple.

[0080] like Figure 2 As shown, the gun head assembly 1 includes a gun head housing 11, a micro switch 12, a hook button unit 13 and a PCBA module 17. Part of the structure of the gun head housing 11 is installed inside the gun body 2, and part of the structure is located outside the head of the gun body 2. The micro switch 12, the hook button unit 13 and the PCBA module 17 are all connected to the gun head housing 11. Specifically, the micro switch 12 is installed above the gun head housing 11 and is located below the hook button unit 13. When the hook button unit 13 is pressed, the hook button unit 13 can trigger the micro switch 12. Part of the PCBA module 17 enters the interior of the gun head housing 11, thereby being connected to the gun head housing 11 as a whole, making it convenient for the gun head assembly 1 to be installed into the gun body 2 together.

[0081] like Figure 3 As shown, the gun head assembly 1 also includes a mounting bracket 14, a pin assembly 15, and a temperature detection unit 16. The mounting bracket 14 is located between the PCBA module 17 and the gun head housing 11. The PCBA module 17 is directly plugged into the mounting bracket 14. The pin assembly 15 and the temperature detection unit 16 are both mounted on the mounting bracket 14 and then connected to the gun head housing 11.

[0082] In this embodiment, the PCBA module 17 integrates all charging functional modules. By integrating the PCBA module 17 into the integrated charging gun 10, there is no need for a separate charging pile box, thus realizing a pile-less charging gun. Furthermore, the integrated charging gun takes up little space, has a compact structure, and is more flexible to install.

[0083] Furthermore, if Figure 2-Figure 3 As shown, the hook button unit 13 includes a rotating shaft 131, a torsion spring 132 and a button 133;

[0084] like Figure 4As shown, the top surface of the gun head housing 11 is provided with a mounting groove 111, and a micro switch mounting position and a rotating shaft hole 112 are provided in the mounting groove 111. The micro switch 12 is installed on the micro switch mounting position, the rotating shaft 131 is installed on the rotating shaft hole 112, the torsion spring 132 is installed on the rotating shaft 131, and the button 133 rotates around the rotating shaft 131. The button 133 includes a pressing end 133a and a hook end 133b. The pressing end 133a extends from the button 133 hole 21, and the hook end 133b extends out of the mounting groove 111.

[0085] Specifically, Figure 4 As shown, the mounting groove 11 is a rectangular groove provided on the top surface of the gun head housing 11. The top of the mounting groove 11 is open, and the bottom of the mounting groove 11 is provided with a micro switch mounting position, and the micro switch 12 is sealedly connected to the micro switch mounting position. A rotating shaft hole 112 is provided on each side wall of the mounting groove 11.

[0086] like Figure 3 As described, during installation, after the rotating shaft 131 passes through the button 133 and the torsion spring 132, the two ends of the rotating shaft 131 are respectively inserted into the rotating shaft hole 112. The button 133 can rotate around the rotating shaft 131, and the torsion spring 132 can reset the button 133.

[0087] like Figure 1 As shown, the button 133 includes a pressing end 133 a and a hook end 133 b . The pressing end 133 a extends from the button hole 21 , and the hook end 133 b extends from the mounting slot 111 and is located outside the gun body 2 .

[0088] When assembling, Figure 10 As shown, a push block 18 is placed below the hook end 133b. This push block 18 lifts the button 133 and tilts it toward the pressing end 133a, lowering the height of the pressing end 133a. This allows the gun head assembly 1 to pass through the opening in the head of the gun body 2 and into the interior of the gun body 2, without the pressing end 133a interfering with the gun body 2. When the pressing end 133a is able to enter below the button hole 21, the gun head assembly 1 and the gun body 2 are fully assembled. At this point, the push block 18 is removed. Under the action of the torsion spring 132, the pressing end 133a of the button 133 tilts upward and extends upward from the button hole 21, while the hook end 133b tilts downward and contacts the gun head housing 11, completing the installation of the gun head assembly 1 and the gun body 2. Since the pressing end 133a extends upward from the button hole 21, it facilitates the user's ability to press the button 133. When the user stops pressing the button 133, the torsion spring 132 resets the button 133.

[0089] In this embodiment, due to the special position of the button 133, no interference will occur during the installation of the gun head assembly 1 and the integrally formed gun body 2.

[0090] Further, if Figure 5-Figure 6 As shown, the gun head housing 11 also includes a receiving portion 113, a retaining ring 114 and a plug-in portion 115. The mounting bracket 14 is installed in the receiving portion 113. The retaining ring 114 is located between the receiving portion 113 and the plug-in portion 115 and blocks the head opening of the gun body 2. A hook opening 116 is provided above the retaining ring 114. The hook end 133b extends from the hook opening 116 to above the plug-in portion 115. The plug-in portion 115 is located outside the gun body 2 for docking with an external charging port.

[0091] Specifically, the retaining ring 114 is used to connect to the head opening of the gun body 2. The retaining ring 114 and the gun body 2 can be connected by bolts or adhesive. The retaining ring 114 is provided with a hook opening 116, so that the hook end 133b extends from the hook opening 116 to the outside of the gun body 2, thereby allowing the ejector block 18 to be placed from the outside.

[0092] The receiving portion 113 is located inside the retaining ring 114 and is inserted into the interior of the gun body 2. In addition, the mounting bracket 14 and part of the PCBA module 17 are installed inside the receiving portion 113, making the installation of the PCBA module 17 more secure and stable.

[0093] The plug-in portion 115 is located outside the retaining ring 114 and outside the gun body 2 for docking with the external charging port. The plug-in portion 115 is provided with a plurality of plug holes for docking with the terminals on the charging port. This part is prior art and will not be described in detail.

[0094] Further, if Figure 5-Figure 6 As shown, a slot 1131 is provided on the inner wall of the receiving portion 113 , and a buckle 141 is provided on the outer wall of the mounting bracket 14 . After the mounting bracket 14 enters the receiving portion 113 , the buckle 141 is snapped into the slot 1131 .

[0095] Specifically, two buckles 141 are provided on the lower surface of the outer wall of the mounting bracket 14, and two corresponding slots 1131 are provided on the lower surface of the inner wall of the receiving portion 113. When the mounting bracket 14 is inserted into the receiving portion 113, the buckles 141 snap into the slots 1131, thereby achieving a fixed connection between the mounting bracket 14 and the receiving portion 113.

[0096] Further, if Figure 5-Figure 6 As shown, a guide rail 1132 is provided on the inner wall of the receiving portion 113 , and a guide groove 142 is provided on the outer wall of the mounting bracket 14 . When the mounting bracket 14 enters the receiving portion 113 , the guide groove 142 slides along the guide rail 1132 .

[0097] Specifically, the lower surface of the outer wall of the mounting bracket 14 is provided with a guide groove 142, located between the two latches 141. A corresponding guide rail 1132 is provided on the lower surface of the inner wall of the receiving portion 113. When the mounting bracket 14 is inserted into the receiving portion 113, the guide groove 142 slides along the guide rail 1132, which guides the mounting bracket 14, allowing the latches 141 to engage with the slots 1131.

[0098] Further, if Figure 6 As shown, the pin assembly 15 includes a first pin 151 and a second pin 152 , the first pin 151 is connected to the temperature detection unit 16 , and the second pin 152 is connected to the PCBA module 17 ;

[0099] The mounting bracket 14 includes a first pin groove 143 and a second pin groove 144 . The first pin groove 143 is located above the second pin groove 144 . The first pin 151 is installed in the first pin groove 143 , and the second pin 152 is installed in the second pin groove 144 .

[0100] Specifically, the first pin 151 includes a CP / CC pin, where the CP pin (Control Pilot): The CP pin is a control pilot signal line used for communication and control between the charging gun and the vehicle. It transmits charging parameters such as the maximum allowable charging current and charging connection status through a PWM (pulse width modulation) signal. The charging gun sends a PWM signal to the vehicle through the CP signal line. The vehicle identifies the maximum allowable current of the charging pile by detecting the duty cycle of the PWM signal and adjusts its own charging strategy accordingly. At the same time, the CP signal is also used in the handshake process between the charging gun and the vehicle to ensure the safety and reliability of the charging process.

[0101] CC pin (Connection Confirm): The CC pin is a charging connection confirmation signal line used to detect the physical connection between the charging gun and the vehicle. When the charging gun is inserted into the vehicle's charging port, the CC pin contacts the corresponding pin on the vehicle, forming a closed circuit. The vehicle determines whether the charging gun is properly inserted by detecting the resistance or voltage value of the CC pin and activates the charging system accordingly.

[0102] Second pins 152 include L / N / PE pins. The L pin (Live) is the phase line (hot wire) of AC power, responsible for transmitting AC power to the electric vehicle's charging system. In single-phase AC charging, the L pin is typically used; in three-phase AC charging, pins L1, L2, and L3 may be used.

[0103] N pin (Neutral): The N pin is the neutral wire of AC power, providing a return path for the current, ensuring that the current can complete its circuit. The neutral wire is an integral part of an AC circuit, forming a complete current loop along with the hot wire.

[0104] PE pin (Protective Earth): The PE pin is a grounding wire used for electrical safety. It conducts leakage current from the device casing to the ground, preventing damage to personnel and equipment caused by electrical short circuits or leakage due to equipment failure. During charging, the PE pin is connected to the vehicle's grounding system to ensure safe grounding of the charging equipment and vehicle.

[0105] Furthermore, if Figure 6 and Figure 8 As shown, the temperature detection unit 16 includes two thermistors 161 , and a heat-conducting colloid 162 is provided outside the thermistors 161 ;

[0106] Two adhesive grooves 145 are provided below the second pin groove 144 on the mounting bracket 14 . The thermistor 161 and the thermally conductive adhesive 162 are installed in the adhesive grooves 145 . The installed thermally conductive adhesive 162 contacts the second pin 152 .

[0107] Specifically, Figure 6 As shown, the thermistor 161 and the thermally conductive colloid 162 are integrally formed.

[0108] like Figure 8 As shown, the thermal conductive adhesive 162 is inserted into the adhesive groove 145. Since the adhesive groove 145 is close to the second pin groove 144, especially the L / N pin, the thermal conductive adhesive 162 is squeezed and contacts the L / N pin, completing the accurate temperature detection of the L / N pin by the thermistor 161.

[0109] Furthermore, if Figure 7-Figure 9 As shown, the PCBA module 17 includes a PCB board 171 , a positioning plate 146 is provided horizontally below the mounting bracket 14 , and a front end of the PCB board 171 is mounted above the positioning plate 146 .

[0110] The connection between the PCB board 171 and the positioning plate 146 ensures the horizontal positioning of the PCB board, ensures parallelism with the L / N / PEpin needles, and ensures the assembly dimensions between the entire gun head assembly 1 and the gun body 2.

[0111] Preferably, if Figure 8-Figure 9 As shown, the left and right sides of the mounting bracket 14 extend outwards from the limiting plates 147. Figure 11As shown, after the mounting bracket 14 is inserted into the receiving portion 113 , the limiting plate 147 contacts the edge of the receiving portion 113 , limiting the insertion depth of the mounting bracket 14 .

[0112] Preferably, if Figure 11 As shown, a sealing ring 117 is provided on the outer wall of the receiving portion 113 , and the sealing ring 117 is used to be sealed and connected with the inner wall of the gun body 2 to prevent external liquid from entering the interior of the gun body 2 .

[0113] Furthermore, if Figure 12-14 As shown, the gun tail assembly 3 includes a rubber part 31, a sheath 32, a first wire clamp 33 and a second wire clamp 34. The outer edge of the rubber part 31 is sealed with the inner wall of the gun body 2 of the charging gun, and the inner edge of the rubber part 31 is sealed with the cable 30. The sheath 32 is sleeved on the outside of the cable 30. The first wire clamp 33 and the second wire clamp 34 are spliced together along the axial direction perpendicular to the cable 30 and connected to the rubber part 31 and the sheath 32. The first wire clamp 33 and the second wire clamp 34 are located between the rubber part 31 and the sheath 32 along the axial direction. The outer walls of the first wire clamp 33 and the second wire clamp 34 are clamped with the inner wall of the gun body 2.

[0114] Specifically, Figure 12 As shown, the tail assembly 3 is connected to the gun body 2. The gun body 2 is a hollow shell, and the rubber member 31, the first wire clamp 33, and the second wire clamp 34 are installed inside the shell of the gun body 2. The sheath 32 is used to block the tail of the gun body 2. A portion of the cable 30 passes through the sheath 32, and the other portion is located in the gun body 2 and connected to the charging head of the charging gun (not shown). The charging head is installed at the head of the gun body 2.

[0115] like Figure 13 As shown, the rubber part 31 , the sheath 32 , the first wire clamp 33 and the second wire clamp 34 are assembled on the outside of the cable 30 , forming a sealing mechanism at the tail of the charging gun, and then installed together on the gun body 2 .

[0116] like Figure 14 As shown, the rubber member 31 is made of an elastic material. The shape of the outer edge of the rubber member 31 is the same as the inner wall of the rear end of the gun body 2. The outer wall of the rubber member 31 and the inner wall of the gun body 2 have an interference fit, achieving a sealed connection and preventing external liquid from entering the interior of the gun body 2. The inner edge of the rubber member 31 has a through hole, and the cable 30 passes through the through hole and is sealed with the through hole.

[0117] The center of the sheath 32 is perforated and is sleeved on the outside of the cable 30 . The sheath 32 is arranged on the outside of the rubber member 31 and maintains a certain distance from the rubber member 31 .

[0118] The first and second clamps 33, 34 are positioned between the rubber member 31 and the sheath 32 along the axis of the cable 30. The first clamp 33 is positioned above the second clamp 34 in a direction perpendicular to the axis of the cable 30. The first and second clamps 33, 34 are first connected to the rubber member 31 and the sheath 32, and then the first clamp 33 and the second clamp 34 are fixedly connected, thereby integrally assembling the rubber member 31, the sheath 32, the first clamp 33, and the second clamp 34.

[0119] The assembled rubber part 31, sheath 32, first wire clamp 33 and second wire clamp 34 are installed in the gun body 2, wherein the outer edge of the rubber part 31 is sealed with the inner wall of the gun body 2, the outer walls of the first wire clamp 33 and the second wire clamp 34 are clamped with the inner wall of the gun body 2, and the sheath 32 is used to block the tail opening of the gun body 2, thereby finally achieving the sealing of the tail of the gun body 2.

[0120] In this embodiment, because the first and second clamps are also engaged with the gun body, the rubber member and the sheath are not easily loosened, and the connection to the gun body is secure, ensuring the stability of the rubber member and thus the sealing performance. Furthermore, because the first and second clamps are joined perpendicular to the axis and connected to the rubber member and the sheath, installation is easy.

[0121] Further, if Figure 14 As shown, the first wire clamp 33 and the second wire clamp 34 are connected perpendicular to the axis by screws or bolts 35. After the first wire clamp 33 and the second wire clamp 34 are assembled perpendicular to the axis, two bolts 35 are inserted into the first wire clamp 33 and the second wire clamp 34 from the upper and lower directions respectively to achieve a fixed connection between the first wire clamp 33 and the second wire clamp 34.

[0122] Optionally, the first wire clamp 33 and the second wire clamp 34 may be connected by snapping or plugging.

[0123] Furthermore, the first wire clamp 33 and the second wire clamp 34 are connected to the sheath 32 via a nested assembly. The first wire clamp 33 and the second wire clamp 34 are respectively connected to the sheath 32 along a direction perpendicular to the axis via the nested assembly.

[0124] Preferably, if Figure 15-16 As shown, the nested assembly includes a belay groove 341 and a belay edge 321 . The belay groove is provided on one end surface of the first wire clamp 33 and the second wire clamp 34 , and the belay edge 321 is provided on the sheath 32 .

[0125] Specifically, Figure 15 As shown, an arc-shaped embedding groove 341 is provided on one end surface of the second wire clamp 34 , and an arc-shaped embedding groove 31 is symmetrically provided on the first wire clamp 33 .

[0126] like Figure 16As shown, a circular edge 321 is provided on the inner side of the sheath 32. When the first clamp 33 is moved downward, the upper half of the edge 321 is embedded in the embedding groove 31 of the first clamp 33. When the second clamp 34 is moved upward, the lower half of the edge 321 is embedded in the embedding groove 341 of the second clamp 34, thereby completing the installation of the first clamp 33 and the second clamp 34 to the sheath 32.

[0127] Optionally, the embedded edges may be provided on the end surfaces of the first wire clamp 33 and the second wire clamp 34 , and the embedded grooves may be provided on the inner side surface of the sheath 32 .

[0128] Furthermore, if Figure 15 As shown, a positioning edge 343 is provided on the embedding groove 341, and the positioning edge 343 is used to prevent the sheath 32 from rotating around the axis direction.

[0129] Specifically, the positioning edge 343 is located at one end of the embedding groove 341 and can be a flat surface or an inclined surface. The embedding edge 321 is provided with a positioning surface corresponding to the positioning edge 343. The engagement between the embedding groove and the embedding edge 321 can restrict the movement of the sheath 32 along the axis, while the positioning edge can restrict the rotation of the sheath 32 about the axis, thereby limiting the movement of the sheath 32 in all directions.

[0130] Furthermore, the first wire clamp 33 and the second wire clamp 34 are connected to the rubber member 31 via a positioning assembly.

[0131] Preferably, if Figure 17-18 As shown, the positioning assembly includes a positioning protrusion and a positioning groove. The positioning protrusion is provided on the other end surface of the first wire clamp 33 and the second wire clamp 34 , and the positioning groove 311 is provided on the rubber member 31 .

[0132] Specifically, Figure 17 As shown, the first wire clamp 33 is provided with two positioning protrusions 332 , and the second wire clamp 34 is provided with two positioning protrusions 342 .

[0133] like Figure 18 As shown, there are four positioning grooves 311 on the rubber member 31. When the first wire clamp 33 and the second wire clamp 34 are connected to the rubber member 31 in a direction perpendicular to the axis, the rubber member 31 undergoes a certain elastic deformation, allowing the positioning protrusion 332 to slide over the end surface of the rubber member 31 and snap into the positioning groove 311.

[0134] Because the rubber member 31 has multiple sealing edges 312 on its outer edge and multiple sealing edges 313 on its inner edge, the rubber member 31 is first connected to the cable 30, then the sheath 32 is placed over the cable 30, and finally the first and second clamps 33, 34 are connected to the rubber member 31 and sheath 32 in a direction perpendicular to the axis.

[0135] Optionally, the first wire clamp 33 , the second wire clamp 34 and the rubber member 31 may also be connected through a nested assembly.

[0136] Further, if Figure 19 As shown, the inner walls of the first clamp 33 and the second clamp 34 are provided with a plurality of teeth 44 , and the teeth 44 are tightly connected to the cable 30 .

[0137] like Figure 20 As shown, when the first wire clamp 33 and the second wire clamp 34 are assembled, the multiple teeth 44 press the cable 30 in the middle, achieving a tight connection with the cable 30 and fixing the positions of the first wire clamp 33 and the second wire clamp 34 in the axial direction.

[0138] Further, if Figure 21-22 As shown, the outer walls of the first and second clamps 33, 34 are provided with a plurality of spaced hooks 36. The inner wall of the gun body 2 is provided with a plurality of slots 22. The hooks 36 snap into the slots 22 along the axial direction, thereby securing the first and second clamps 33, 34 to the gun body 2. Since the first and second clamps 33, 34 are connected to the rubber member 31, once the first and second clamps 33, 34 are fixedly connected to the gun body 2, the rubber member 31 is prevented from moving along the axial direction relative to the gun body 2, thereby ensuring the sealing performance of the rubber member 31.

[0139] Further, if Figure 21-22 As shown, the outer walls of the first wire clamp 33 and the second wire clamp 34 are provided with a plurality of guide bars 37 arranged at intervals, and the inner wall of the gun body 2 is provided with a plurality of guide grooves 23, and the guide bars 37 slide into the guide grooves 23 along the axial direction.

[0140] The guide bar 37 cooperates with the guide groove 23 to facilitate the sliding of the first wire clamp 33 and the second wire clamp 34 into the gun body 2. When the guide bar 37 is completely slid into the guide groove 23, the hook 36 engages with the groove 22. The cooperation between the guide bar 37 and the guide groove 23 also prevents the first wire clamp 33 and the second wire clamp 34 from rotating about the axis relative to the gun body 2, thereby limiting and fixing the first wire clamp 33 and the second wire clamp 34 in all directions.

[0141] In other embodiments of the present invention, Figure 23 As shown, the pile-less charging gun assembly includes a gun mount 20 and the integrated charging gun 10 in any of the above embodiments, and the integrated charging gun 10 is hung on the gun mount 20 .

[0142] The gun mount 20 only holds the integrated charging gun 10 in a relatively fixed position; no functional modules or cables required for charging are housed within the gun mount 20. All functional modules are integrated into the integrated charging gun 10, resulting in a simple overall structure and more flexible installation.

[0143] Further, if Figure 24As shown, the gun mount 20 includes a base 201, an empty seat 202 and a cover plate 203. The base 201 includes an inserting cavity 2011 and a hanger 2012. The empty seat 202 is rotatably connected to the inserting cavity 2011. The cover plate 203 is covered on the top of the inserting cavity 2011.

[0144] The gun head assembly 1 of the integrated charging gun 10 is plugged into the empty seat 202 , and the gun tail assembly 3 is mounted on the hanger 2012 .

[0145] Specifically, the empty seat 202 is a hollow cylindrical structure, and the empty seat 202 is rotatably connected to the base 201 via a torsion spring 2021. When the gun head assembly 1 is inserted into the empty seat 202, the gun head assembly 1 and the empty seat 202 can rotate relative to the base 201 together.

[0146] like Figure 25 As shown, when the integrated charging gun 10 is mounted on the gun mount 20 , the gun head assembly 1 is first inserted into the empty seat 202 , and the gun tail assembly 3 is not hung on the mount 2012 at this time.

[0147] like Figure 26 As shown, the integrated charging gun 10 and the empty seat 202 are rotated downward relative to the base 201 , and the gun tail assembly 3 is hung on the hanger 2012 to complete the installation of the integrated charging gun 10 .

[0148] Similarly, when the integrated charging gun 10 needs to be used, the gun tail assembly 3 is first rotated upward and outward to separate it from the bracket 2012. Then, the gun head assembly 1 is pulled out from the empty seat 202. The empty seat 202 is reset under the action of the torsion spring 2021.

[0149] Preferably, if Figure 24 As shown, the socket 202 is also provided with a hook 2022 that engages with the hook end 133b of the integrated charging gun 10. When the gun head assembly 1 is inserted into the socket 202, the hook end 133b engages with the hook 2022, preventing the gun head assembly 1 from accidentally falling out of the socket 202. When the integrated charging gun 10 is needed, the button end 133a is pressed to separate the hook end 133b from the hook 2022, and the gun head assembly 1 is then removed from the socket 202.

[0150] This invention integrates the PCBA module within the integrated charging gun, eliminating the need for a separate charging pile box, thus achieving a pile-free charging gun. The integrated charging gun takes up little space, has a compact structure, and offers greater installation flexibility. Furthermore, the gun body is an integrally molded shell structure, and the hook button unit is installed into the gun body along with the gun head assembly, making installation more convenient and concise, while also giving the charging gun a uniform and concise overall appearance.

[0151] The above description is only the principle and preferred embodiment of the present invention. It should be noted that for those skilled in the art, several other variations can be made based on the principle of the present invention, which should also be considered as the scope of protection of the present invention.
