Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, and in particular to a high-strength anti-bending cooling structure for charging gun cables. Background Technology

[0002] Charging new energy vehicles typically requires a charging gun, which connects to a charging box via a charging cable. Traditional charging guns and cables usually lack cooling structures. During charging, these components generate heat, especially at higher charging power levels. In hot weather, excessively high temperatures can accelerate component aging and even damage the charging gun, cable, and the vehicle being charged, posing a significant safety hazard. Therefore, cooling structures for charging guns and cables have been invented. For example, publication number CN216331463U discloses "A Cooling Structure for an Ultra-High Power Charging Gun," which includes a charging pile, a charging gun, and a cooling cable connecting the charging pile and the charging gun. The charging pile has a water tank containing a water pump; the charging gun has a cooling space; and the cooling cable contains a cooling conduit and a cooling channel. One end of the cooling conduit connects to the water pump, and the other end connects to the cooling space. One end of the cooling channel connects to the water tank, and the other end connects to the cooling space. However, the disadvantages of this structure are: First, if the cooling cable is bent, it can affect the flow of the cooling channel, or even cause the cooling channel to become blocked, thus affecting the flow of coolant and resulting in poor cooling effect; Second, the cooling channel is only covered by an outer sheath, which is in direct contact with the ground and is prone to wear. Once it is worn or cracked, coolant will be lost. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a high-strength, bend-resistant cooling structure for charging gun cables that is strong, wear-resistant, prevents bending, ensures coolant flow, and has a good cooling effect.

[0004] The technical solution of the high-strength anti-bending cooling structure for charging gun charging cable of this utility model is as follows: it includes an upper cooling pipe and a lower cooling pipe made of EPDM material, the upper cooling pipe and the lower cooling pipe are attached to each other, one end of the upper cooling pipe and the lower cooling pipe are respectively provided with a bent pipe joint, the other end of the upper cooling pipe and the lower cooling pipe are respectively provided with a straight pipe joint, and two side grooves are formed on both sides of the attachment point of the upper cooling pipe and the lower cooling pipe. The charging cable is respectively placed in the two side grooves, and the outer wall of the upper cooling pipe, the lower cooling pipe and the charging cable is covered with a wear-resistant layer.

[0005] Furthermore, the outer wall of the wear-resistant layer is provided with two or more protective sleeves made of rubber material.

[0006] Furthermore, the wall thickness T1 of the upper and lower cooling pipes is 4 mm, and the inner diameter θ of the upper and lower cooling pipes is 31 mm.

[0007] Furthermore, a thickened layer is provided at the bottom of the upper and lower cooling pipes near the elbow joint, with a wall thickness T2 of 2.5-3 mm and a length of 50-60 cm.

[0008] Furthermore, the wear-resistant layer is made of a PA and PET composite material.

[0009] Furthermore, the upper cooling pipe and the lower cooling pipe are bonded and fixed together with adhesive.

[0010] The beneficial effects of the high-strength anti-bending and cooling structure for a charging gun cable of this utility model are:

[0011] 1. The upper and lower cooling pipes are attached to each other, forming two side grooves on both sides, and the charging cable is placed in the side grooves. On the one hand, this arrangement improves the overall strength of the charging cable and makes it less prone to bending. The upper and lower cooling pipes can also clamp and protect the charging cable. On the other hand, the close fit between the upper and lower cooling pipes and the charging cable is conducive to cooling the charging cable.

[0012] 2. A thickened layer is installed at the bottom of the end of the lower cooling pipe near the charging gun to increase the structural strength of this area and improve its resistance to bending and deformation. This avoids the reduction or blockage of coolant flow due to bending, rather than increasing the overall wall thickness. This makes the cable lighter while ensuring structural strength.

[0013] Third, the addition of a wear-resistant layer and cable sheath ensures that the charging cable is not easily worn even when dragged on the ground, thus guaranteeing its service life. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] This utility model relates to a high-strength, bend-resistant, and cooling structure for a charging gun cable, such as... Figure 1 —As shown in the figure, it includes an upper cooling pipe 1 and a lower cooling pipe 2 made of EPDM material. The upper cooling pipe 1 and the lower cooling pipe 2 are attached to each other. One end of the upper cooling pipe 1 and the lower cooling pipe 2 is provided with a bend joint 3, and the other end of the upper cooling pipe 1 and the lower cooling pipe 2 is provided with a straight joint 4. Two side grooves 5 are formed on both sides of the attachment point of the upper cooling pipe 1 and the lower cooling pipe 2. A charging cable 6 is respectively placed in the two side grooves 5. The outer wall of the upper cooling pipe 1, the lower cooling pipe 2 and the charging cable 6 is covered with a wear-resistant layer 7.

[0020] Furthermore, the outer wall of the wear-resistant layer 7 is provided with two or more protective sleeves 8 made of rubber material. The protective sleeves 8 are fitted on the outer wall of the wear-resistant layer 7 to further protect the cable and reduce its wear.

[0021] Furthermore, the wall thickness T1 of the upper cooling pipe 1 and the lower cooling pipe 2 is 4mm, and the inner diameter θ of the upper cooling pipe 1 and the lower cooling pipe 2 is 31mm.

[0022] Furthermore, a thickened layer 9 is provided at the bottom of the upper cooling pipe 1 and the lower cooling pipe 2 near the elbow joint 3. The wall thickness T2 of the thickened layer 9 is 2.5-3mm, and the length of the thickened layer 9 is 50-60cm. When people lift the charging gun for charging, the end of the cable near the charging gun is prone to bending downwards. The thickened layer 9 at the bottom of the upper cooling pipe 1 and the lower cooling pipe 2 near the elbow joint 3 (i.e., the end near the charging gun) increases the structural strength at that point and improves the resistance to bending and deformation, preventing a reduction in coolant flow or blockage due to bending. Rather than increasing the overall wall thickness, this design makes the cable lighter while ensuring structural strength.

[0023] Furthermore, the wear-resistant layer 7 is made of a PA and PET composite material. The PA and PET composite material is made into a woven mesh and wrapped around the outer wall of the upper cooling pipe 1, the lower cooling pipe 2, and the charging cable 6.

[0024] Furthermore, the upper cooling pipe 1 and the lower cooling pipe 2 are bonded and fixed at the joint with adhesive.

[0025] This utility model discloses a high-strength, bend-resistant cooling structure for a charging gun cable. It comprises an upper cooling pipe 1 and a lower cooling pipe 2 made of EPDM material, with an inner diameter of 31mm, an outer diameter of 39mm, and a wall thickness of 4mm. One of the upper cooling pipes 1 and 2 is a water inlet pipe, and the other is a water outlet pipe. They are fitted together vertically and fixed at the joint with adhesive. A bent pipe connector 3 is provided at one end of each of the upper and lower cooling pipes 1 and 2, and the two are fixed together by a snap-fit. The other end of the bent pipe connector 3 is connected to the charging gun. A straight pipe connector 4 is provided at the other end of each of the upper and lower cooling pipes 1 and 2, and the two are fixed together by a snap-fit. The other end of the straight pipe connector 4 is connected to a cooling machine. Two side grooves 5 are formed on both sides of the joint of the upper and lower cooling pipes 1 and 2. Two charging cables 6 are placed in the side grooves 5. One end of the charging cable 6 is connected to the charging gun, and the other end is connected to the charging box. One side of the charging cable 6 is connected to the upper and lower cooling pipes. 1 and 2 are bonded together to form a whole. The upper and lower cooling pipes 1 and 2 clamp and protect the charging cable 6. A wear-resistant layer 7 is wrapped around the entire upper and lower cooling pipes 1 and 2 and the charging cable 6. When people lift the charging gun to charge the new energy vehicle, the charging box provides power to the new energy vehicle through the charging cable 6 and the charging gun. At the same time, the cooling machine (which has a tank containing coolant and a water pump for conveying coolant, the specific structure of which is existing technology) delivers coolant to the upper cooling pipe 1 or the lower cooling pipe 2. The coolant is then delivered to the charging gun through the upper cooling pipe 1 or the lower cooling pipe 2. The charging gun has a coolant circuit structure (the coolant circuit structure in the charging gun is existing technology, see publication number CN219257094U). The coolant flows back to the lower cooling pipe 2 or the upper cooling pipe 1 through the charging gun, and finally back to the cooling machine. Through the circulation of coolant, the charging cable 6 is cooled.

Any modifications, equivalent substitutions, improvements, etc. made to the present utility model within the spirit and protection scope of the claims shall fall within the protection scope of the present utility model.
