For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0038] Example 1:

[0039] This embodiment provides a charging and discharging integrated gun, including a gun head 1, a gun housing 2, and a circuit assembly 4. The gun head 1 is mounted on the head of the gun housing 2, and the circuit assembly 4 is mounted inside the gun housing 2. The circuit assembly 4 includes:

[0040] A mounting base 3, comprising a first fixing portion 31 and a second fixing portion 32, wherein the first fixing portion 31 is provided at the bottom of the mounting base 3 along the first direction Z, and the second fixing portion 32 is provided at the end of the mounting base 3 along the second direction X;

[0041] A circuit board 41 is mounted on the mounting base 3 and includes a control module, a power module, a switch module, and a bidirectional protocol module. The bidirectional protocol module is configured to cooperate with the control module, the power module, and the switch module to switch between charging and discharging functions.

[0042] A plurality of plug terminals 5, which are installed in the gun head 1 and are electrically connected to the circuit board 41;

[0043] Among them, the gun housing 2 is provided with a first limiting rib 21 and a second limiting rib 22, the first fixing portion 31 and the first limiting rib 21 are slidably connected along the second direction X and abut against each other along the first direction Z, and the two ends of the second fixing portion 32 along the third direction Y respectively abut against the gun head 1 and the second limiting rib 22.

[0044] In this technical solution, a circuit board 41 is mounted and fixed on a mounting base 3, which is disposed within the gun housing 2. One end of the circuit board 41 is electrically connected to the plug-in terminal 5 within the gun head 1 through the head of the gun housing 2, and the other end of the circuit board 41 is electrically connected to the wires and cables through the rear of the gun housing 2. When the charging and discharging gun is in operation, the gun head 1 is plugged into the car's charging port. The charging and discharging gun can receive externally transmitted control commands based on the control module on the circuit board 41, thereby automatically identifying the car's charging or discharging mode. It then controls the working state of the two-way protocol module based on the control commands, thereby enabling charging or discharging through the charging and discharging gun, realizing the integrated charging and discharging functions, which is highly practical.

[0045] The number of first fixing portions 31 at the bottom of the mounting base 3 can be multiple. The number of first limiting ribs 21 provided at the bottom of the gun housing 2 along the first direction Z matches the number of first fixing portions 31. The first fixing portion 31 is composed of two protrusions 311, with a sliding groove formed between the two protrusions 311 for sliding engagement between the first limiting rib 21 and the sliding groove. The first limiting rib 21 is provided with a first engaging portion 211, and one of the protrusions 311 is provided with a second engaging portion 312.

[0046] By utilizing the sliding cooperation between the first limiting rib 21 and the slide groove, the mounting base 3 can be stably slid into the gun case 2 along the second direction X for placement, and the displacement of the mounting base 3 in the third direction Y is limited. At the same time, the first clamping portion 211 and the second clamping portion 312 abut against each other along the first direction Z, thereby limiting the displacement of the mounting base 3 in the first direction Z.

[0047] The second limiting ribs 22 are disposed on both sides of the gun case 2 along the third direction Y. The second fixing portion 32 is disposed on one end of the mounting base 3, located near the head of the gun case 2, along the second direction X. The second fixing portion 32 is U-shaped, with extensions disposed at both ends of the second fixing portion 32 along the third direction Y. When the mounting base 3 is installed into the gun case 2 through the cooperation of the first fixing portion 31 and the first limiting rib 21, one side of the extension along the second direction X abuts against the end of the second limiting rib 22, and the gun head 1 is then inserted and fixed to the head of the gun case 2. The other side of the extension along the second direction X abuts against the gun head 1, and the gun head 1 and the second limiting rib 22 clamp and secure the second fixing portion 32, thereby limiting the displacement of the second fixing portion 32 in the second direction X.

[0048] In summary, the integrated control module, power module, switch module, and bidirectional protocol module on the circuit board 41 within the gun housing 2 enable the integration of both charging and discharging functions. The integrated circuit board 41 is mounted and fixed on the mounting base 3. The first limiting rib 21 and the first fixing portion 31 are slidably connected to limit the displacement of the mounting base 3 within the gun housing 2 along the third direction Y. The first limiting rib 21 and the first fixing portion 31 are engaged in a first direction Z to limit the displacement of the mounting base 3 within the gun housing 2 along the first direction Z. The second limiting rib 22 and the gun head 1 clamp the second fixing portion 32 to limit the displacement of the mounting base 3 within the gun housing 2 along the second direction X. This allows the circuit board 41 and the mounting base 3 to be securely mounted within the gun housing 2, thereby ensuring that the charging and discharging gun can perform stable charging and discharging operations during use.

[0051] Furthermore, an insert block 33 is provided on the mounting base 3, and a limiting hole is provided on the circuit board 41;

[0052] The insert block 33 is plugged into and matched with the limiting hole.

[0053] In this technical solution, an insert block 33 protruding upward along the first direction Z is also provided on the mounting base 3, and a limiting hole is opened on the circuit board 41. The insert block 33 is plugged into and matched with the limiting block, and is fixed with glue, thereby realizing a fixed connection between the circuit board 41 and the mounting base 3.

[0063] In this technical solution, pressing the control button 63 pushes the end of the locking plate 62 downward, compressing the return spring 64 and causing the locking plate 62 to swing, causing the locking hook 65 of the locking plate 62 to tilt upward. When the charging and discharging gun is plugged into the vehicle's charging port, releasing the control button 63 causes the return spring 64 to return to its original position, returning the depressed end of the locking plate 62 to its original position, thereby driving the locking hook 65 back to its original position and engaging with the vehicle's charging port, thereby locking the charging and discharging gun to the vehicle's charging port.
