Description

Technical Field

[0001] The present invention relates to the technical field of charging pile cables, and in particular to a freeze-proof low-temperature charging pile cable. Background Art

[0002] Charging pile cables are used to connect charging piles and electric vehicles. Charging pile cables usually consist of plugs at both ends and a cable in the middle. They are used to transfer electrical energy from the charging pile to the battery pack of the electric vehicle for charging. Charging pile cables generally have properties such as waterproofing, high temperature resistance, and wear resistance to ensure safe and reliable charging operations. Different types of electric vehicles may require charging pile cables of different specifications. Therefore, when selecting charging pile cables, it is necessary to consider matching the electric vehicle model and charging power requirements. Charging pile cables play an important role in promoting the popularization of electric vehicles and facilitating charging for users.

[0003] It is now found that the charging pile cable in the prior art is typically as disclosed in CN117219335A, a charging pile cable, including a cable body and a plurality of support components installed at intervals on the outer wall of the cable body; the support component includes a mounting portion installed on the outer wall of the cable body, a rotating ring rotatably installed on the outer wall of the mounting portion, and a friction ring installed on the outer wall of the rotating ring, the rotating ring and the cable body are coaxially arranged, and the friction ring and the rotating ring are coaxially arranged; the rotating ring is detachably connected to the outer wall of the rotating ring, and the rotating ring can synchronously drive the friction ring to rotate when rotating. The present application has the effect of reducing the wear of the cable body.

[0004] When existing charging pile cables are used in cold weather, the low temperature can easily make the cable material brittle and reduce its toughness. The low temperature shrinkage can also cause stress concentration, increasing the risk of breakage. At the same time, the insulation performance of the cable is reduced, making it prone to breakdown or short circuits. When the cable is treated with antifreeze treatment, it is difficult to ensure that the antifreeze effect is uniform and sufficient. To address the above problems, existing equipment needs to be improved. Summary of the invention

[0005] The purpose of the present invention is to provide a freeze-proof and low-temperature charging pile cable to solve the problem that the existing charging pile cables proposed in the above background technology, when used in cold weather, the low temperature easily makes the cable material brittle and the toughness weakened, and the low-temperature shrinkage causes stress concentration, increasing the risk of breakage. At the same time, the insulation performance of the cable is reduced, and it is easy to cause breakdown or short circuit, and it is difficult to ensure uniform and sufficient antifreeze effect when the cable is antifreeze treated.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an antifreeze and low-temperature charging pile cable, comprising a charging pile cable body, an insulation sleeve is fixed on the outside of the charging pile cable body, a liquid inlet pipe is fixed on the top of the insulation sleeve, a fixed channel is fixed on the inner top of the insulation sleeve, a liquid outlet pipe is fixed on the top of the fixed channel, and the liquid outlet pipe runs through the top of the insulation sleeve.

[0007] Preferably, a retaining ring is fixed inside the thermal insulation sleeve, and an opening is formed on the retaining ring.

[0008] By adopting the above technical solution, the retaining ring plays a guiding role for the antifreeze liquid.

[0009] Preferably, the baffle rings are distributed in the insulation sleeve at equal intervals, and the opening directions of two adjacent baffle rings are opposite.

[0010] By adopting the above technical solution, the opening directions of the two adjacent retaining rings are opposite, so that the antifreeze liquid is transported to the right in an "S" shape in the insulation sleeve.

[0011] Preferably, the bottom of the fixed channel is connected to the movable column via a compression spring, and the compression spring is wrapped around the outside of the movable column, and the movable column passes through the bottom of the fixed channel and is connected to the movable sealing plate.

[0012] By adopting the above technical solution, when the antifreeze liquid in the insulation sleeve is in a filled state, the movable sealing plate automatically moves upward and opens the through hole.

[0013] Preferably, a support frame is fixed to the top of the insulation sleeve, and the liquid outlet pipe passes through the support frame.

[0014] By adopting the above technical solution, the support frame can be used to support the position-limiting liquid outlet pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The antifreeze low-temperature charging pile cable can achieve the purpose of continuous heat preservation and antifreeze through the coordinated use of the charging pile cable body, the insulation sleeve, the liquid inlet pipe and the liquid outlet pipe. Before using the device, the liquid inlet pipe and the liquid outlet pipe need to be connected to the antifreeze heating device. The antifreeze heating device can heat the antifreeze, and the antifreeze at a suitable temperature circulates in the insulation sleeve, which is convenient for continuous heat preservation and antifreeze treatment of the charging pile cable body; 2. The antifreeze low-temperature charging pile cable can achieve the purpose of uniform action through the coordinated use of the charging pile cable body, the insulation sleeve and the baffle ring. The baffle ring is provided with an opening, and the openings on the two adjacent baffle rings are in opposite directions, so that the antifreeze liquid can be transported to the right in an "S" shape in the insulation sleeve, so that the antifreeze liquid can fully and evenly act on the charging pile cable body; 3. The antifreeze low-temperature charging pile cable can achieve the purpose of ensuring that the antifreeze liquid is filled through the coordinated use of the set insulation sleeve, fixed channel, through hole, movable sealing plate and liquid outlet pipe. The movable sealing plate seals the through hole at the beginning. When the insulation sleeve is filled with antifreeze liquid, the movable sealing plate is lifted up and the through hole is opened. The antifreeze liquid can pass through the through hole to the fixed channel and flow away through the liquid outlet pipe, ensuring that the insulation sleeve is always full of antifreeze liquid.
