In this context, the charging gun, as a key connecting component between electric vehicles and charging piles, its performance directly affects the efficiency and safety of charging.

[0003] 1. Cooling chamber: A special cooling chamber is built in the charging gun head and the cable conduction part, so that the coolant can fully cover and penetrate all areas where the cable and connector are plugged in, ensuring that the heat can be effectively absorbed and carried away by the coolant.

[0004] 2. Coolant circulation system: including coolant, electronic pump / water pump (as a driving component, it accurately controls the flow and circulation path of the coolant, promotes the circulation of the coolant in the cooling system, and enables the coolant to continuously circulate between absorbing heat and dissipating heat, ensuring the maximum heat dissipation effect), radiator (after the coolant absorbs heat, it dissipates the heat to the external environment through the radiator, so that the coolant temperature is reduced so that it can participate in the circulation cooling again), and liquid storage tank (used to store coolant and provide reserves for the circulation of coolant to ensure that there is enough coolant in the cooling system to continue working).

[0005] 3. Liquid cooling cable: It is an important component of the liquid-cooled charging gun. It contains one DC+ cable, one DC- cable, a ground wire, several signal wires, and a pipe specifically for the flow of coolant.

In view of this, we propose a liquid cooling structure for a super charging gun. Summary of the invention

[0009] The purpose of the present invention is to provide a liquid cooling structure for a super charging gun to solve the technical problem that the existing charging gun heat dissipation structure is relatively single.

Several of the through holes are commonly sleeved with a first liquid cooling tube, and the first liquid cooling tube is annular and wavy. The present invention sets a cooling mechanism, and through thermal expansion and contraction, two heat dissipation effects of annular uniform heat dissipation treatment and local concentrated heat dissipation treatment can be achieved. When the temperature inside the charging gun is uniform, the through holes are arranged in an annular array, so that the first liquid cooling tube is evenly arranged inside the charging gun to achieve uniform liquid cooling and heat dissipation. When the temperature difference inside the charging gun is large, the principle of thermal expansion and contraction is used to make the first support ring tilt, and the first tension spring is used to make several through holes slide toward the tilted position, so that the first liquid cooling tube is concentrated in an arc shape to achieve local efficient liquid cooling and heat dissipation.

At this time, the first spring is used to rearrange the plurality of telescopic shells in a circular array to achieve the flexibility of the cooling structure.

[0022] 3. The elastic rope in the present invention is made of rubber material. When in use, the elastic characteristics of the elastic rope itself enable several bending rods to synchronously move axially to achieve consistency of the device.

During long-term use, when the temperature difference in the charging gun is large, several of the airbags 402 expand through thermal expansion and contraction, and the telescopic rod 404 stretches, so that the first support ring 403 tilts. At this time, the first tension spring 409 applies a pulling force to the telescopic rod 404, so that the relative telescopic shell 407 and the limit rod 408 move toward the inclined position of the first support ring 403, thereby making several perforations 410 arranged in an arc shape, so that the first liquid cooling tubes 411 are concentrated, and local efficient liquid cooling treatment is performed on the charging gun; In the embodiment of the present invention, a fixing assembly 5 is also included, and the fixing assembly 5 includes a plurality of articulated frames 501, and the plurality of articulated frames 501 are fixedly connected to the end surface of the charging gun head 1, and a plurality of bending rods 502 are movably connected inside the plurality of articulated frames 501 through a first latch; The cooling mechanism 4 includes a conical frame 401 and a fixing assembly 5 ; the conical frame 401 is fixedly sleeved inside the housing 101 , and the conical frame 401 is fixedly connected to the charging gun head 1 , and the fixing assembly 5 is arranged on the end surface of the charging gun head 1 .

When the temperature inside the charging gun is high, the liquid pump 302 is turned on and the cooling liquid flows into the circulation pipe 701. The circulation pipe 701 expands and protects the cable 2. When the temperature is balanced, the first spring 602 applies a force to the telescopic shell 407, so that the perforations 410 are arranged in a ring array, and the first liquid cooling tubes 411 are evenly distributed inside the charging gun, so as to achieve a ring-shaped uniform liquid cooling heat dissipation treatment. During long-term use, when the temperature difference in the charging gun is large, several of the airbags 402 expand through thermal expansion and contraction, and the telescopic rod 404 stretches, so that the first support ring 403 tilts. At this time, the first tension spring 409 applies a pulling force to the telescopic rod 404, so that the relative telescopic shell 407 and the limit rod 408 move toward the inclined position of the first support ring 403, thereby making several perforations 410 arranged in an arc shape, so that the first liquid cooling tubes 411 are concentrated, and local efficient liquid cooling treatment is performed on the charging gun.
