Many leading companies in the light, wind, storage, and charging industries are investing heavily in liquid-cooled supercharging cables, smart charging guns, smart charging piles, smart battery swap stations and other equipment. The development momentum of smart liquid cooling module construction is advancing by leaps and bounds, helping to develop a high-quality integrated charging infrastructure system. As a liquid-cooled supercharging cable, it presents a multi-mode, multi-specification, multi-structure, and multi-functional ordinary isolation liquid cooling structure, copper-clad water liquid cooling structure, water-clad copper liquid cooling structure, fully immersed liquid cooling structure, and half-moon-shaped combined liquid cooling structure. Although the structures of various types of liquid-cooled supercharging cables are different, the overall functional goals are the same, and the application insulation and sheath materials are also very different. However, the product has a most common fatal flaw in application, that is, severe leakage occasionally occurs during the application process, which can cause ablation of the connection part of the charging connector at the least, and cause battery fire at the worst, which brings serious psychological shadows to the end users in application. To this end, new energy charging cable manufacturers have explored a path to transform from the liquid cooling channel of the cooling water pipe to the cooling pipe structure mode, and have made bold innovations in the liquid cooling structure and cooling and heat dissipation area, constantly pursuing structural optimization and optimization solutions for the temperature rise effect of the wires.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] See also Figure 1-7 The present invention provides a technical solution for a cabling process and device of a liquid-cooled charging pile supercharging cable:

[0032] Embodiment 1:

[0033] according to Figure 1 and Figure 2 As shown, a cable forming device for a liquid-cooled charging pile supercharging cable includes a traction introduction tooling 1, a shaping tooling 2 and a centralized introduction bakelite mold 8. The traction introduction tooling 1 is a T-shaped stainless steel frame. The positioning groove of the traction introduction tooling 1 consists of two The threading hole position porcelain eye 102 and one 1pcs The horseshoe groove 101 structure is mainly used to realize the positioning of the horseshoe shielded twisted structure 9 of the main power line of the liquid-cooled supercharger cable and the overall structure of the liquid-cooled pipeline, and complete the positioning of the key structure of the cable center. Figure 3 As shown, a horseshoe groove 101 through which a front and rear through-channel opening in the shape of a horseshoe structure can pass is provided at the center position of the vertical frame of the T-shaped stainless steel seat frame traction introduction tooling 1, and two balanced and symmetrical threading holes 102 through which the main power line 92 of the liquid-cooled charging pile cable can pass are provided at two-fifths of the position symmetrically centered on the horseshoe groove 101, so that the two main power lines can pass smoothly. With such a configuration, a horseshoe structure tube 91 and two main power lines 92 are evenly distributed in the same horizontal direction when passing through the traction introduction tooling 1.

[0034] The molding tool 2 consists of two The two guide wheels 202 are mounted on the bearing guide column 201 and are symmetrically coordinated to form a horseshoe structure guide groove 203 in the center. The main function is to ensure that the two insulated main power lines 92 of the liquid-cooled supercharging cable are accurately and symmetrically stuck in the wire groove 911 at the edge of the horseshoe structure tube 91. Its function is to draw force by taking up the wire during the tension-free pay-off process, so as to give play to the self-rotation function of the gyro-shaped rotating structure. After the two main power lines 92 enter the shaping tooling 2 through the traction introduction tooling 1, they are tightly squeezed by the two guide wheels 202, and the two balanced and symmetrical horizontally placed main power lines 92 are evenly, at a uniform speed, and in a uniform direction embedded in the wire groove 911 of the horseshoe structure tube 91 moving in the horizontal direction, completing the overall shaping and positioning of the wire / groove integration, and realizing the integrated coating work for the next high-temperature taping process.

[0035] Centralized import of bakelite molds 8 The centrally-introduced bakelite mold 8 is made of a through groove for the smooth passage of the horseshoe-shielded twisted structure 9. Its main function is to enable the two twisted main power lines and the center-positioned horseshoe-structured tube insulator to pass smoothly and complete the outer diameter shaping, so as to achieve the compact effect and the cabling purpose of positioning, shaping, rounding and sizing after round twisting.

[0036] like Figure 1As shown, the traction and introduction tooling 1, the shaping tooling 2, and the centralized introduction bakelite mold 8 are integrated and installed on the movable tooling base 3, forming the overall structure of the movable guide rail tooling base and the traction and introduction tooling 1, the shaping tooling 2, and the centralized introduction bakelite mold 8, wherein the traction and introduction tooling 1 and the shaping tooling 2 are movably installed on the movable tooling base 3 through the longitudinal large base, the transverse base and the locking bolt components. Specifically, the movable tooling base 3 is installed on the two sliding blocks of the middle fixed bracket of the cage stranding machine. The specific structure of the cage stranding machine is the existing technology and is not shown here. A locking bolt is arranged at the bottom of the movable tooling base 3, which can be adjusted forward, backward, left and right on the fixed bracket of the cage stranding machine and locked and fixed. The movable tooling base 3 carries the traction and introduction tooling 1 and the shaping tooling 2. A longitudinal sliding plate 5 is slidably installed on one side of the movable tooling base 3, and a bracket seat 4 is vertically fixed above the longitudinal sliding plate 5. The bracket seat 4 is composed of a telescopic cylindrical alloy steel frame structure, on which two locking bolts for locking are arranged. The top of the alloy steel frame structure bracket seat 4 is a T-shaped integrated stainless steel seat frame traction and introduction tooling 1; longitudinal slide rail grooves 501 are symmetrically arranged on the longitudinal sliding plate 5, and a positioning bolt that penetrates the longitudinal slide rail groove 501 is installed on the movable tooling base 3. The longitudinal sliding plate 5 can slide forward and backward on the movable tooling base 3 through the longitudinal slide rail groove 501 to adjust the position of the traction and introduction tooling 1, and lock and position it by the positioning bolt.

[0037] Two transverse sliding plates 6 are symmetrically installed on the movable tooling base 3 on the front side of the longitudinal sliding plate 5 for sliding movement. A column 7 is vertically fixed to the proximal end of the two transverse sliding plates 6. The shaping tooling 2 is installed on the column 7. Specifically, a bearing guide column 201 is mounted on the column 7, and a guide wheel 202 is rotatably mounted on the bearing guide column 201, and a locking bolt is installed on the bearing guide column 201. The height of the shaping tooling 2 on the column 7 can be adjusted by the locking bolt, so that the horseshoe structure guide groove 203 of the shaping tooling 2 is aligned with the horseshoe groove 101, so that the self-rotation function of the gyro-shaped rotating structure can be exerted, and the two balanced and symmetrical horizontally placed main power lines 92 are evenly, at a uniform speed, and in a uniform direction embedded in the wire groove 911 of the horseshoe structure tube 91 moving in the horizontal direction. A transverse slide rail groove 601 is provided on the transverse sliding plate 6, and a positioning bolt passing through the transverse slide rail groove 601 is installed on the movable tooling base 3. The two molding tools 2 can adjust their positions to be closer to or farther away from each other through the transverse sliding plate 6, and the positions of the molding tools 2 can be locked by the positioning bolts, thereby forming a guide groove that matches the horseshoe shielded twisted structure 9.

[0038] The movable main structure tooling base, the T-shaped horizontal main power line plus horseshoe structure tube passing tooling and the detachable cylindrical support gyro-shaped rotatable guide wheel wire feeding tooling form the main part of the special-shaped device for the liquid-cooled charging pile supercharging cable cabling process. Its main function is: through the traction of the horizontal guide wire and the horseshoe structure plastic parts, the two main power lines are horizontally positioned under the fixed horizontal force and the fixed semicircular structure, plus the gyroscopic rotation force of the two fixed guide wheels, the two main power lines are reliably and firmly embedded in the horizontally advancing horseshoe structure tube.

[0039] When used specifically, the present invention is a cabling device for a liquid-cooled charging pile supercharging cable. Through the combined action of the centrifugal force and centripetal force generated by the two left-right symmetrical main power lines 92 and two rotating guide wheels in the liquid-cooled supercharging pile cable, the left-right symmetrical main power lines 92 are horizontally embedded in the two large semicircular wire grooves 911 of the horseshoe structure tube 91 shaped like a horseshoe structure, thereby achieving horizontal positive fixed positioning. Since the mechanical horizontal centrifugal force of the cage stranding machine causes the core wire to move in the tangential direction around the guide wheel 202, and the centripetal force causes the core wire to move in the axial direction of the rotating guide wheel, when the two main power lines 92 simultaneously produce the same-direction horizontal movement, the two main power lines 92 will neither move away from the rotating guide wheel nor approach the rotating guide wheel, and the main power lines 92 actively move in a circular motion around the rotating guide wheel shaft, so that the two main power lines 92 are horizontally embedded in the horseshoe structure tube 91 with a fixed center at a uniform speed. Because the wheel diameter and track size of the rotating zinc alloy guide wheel are in a truncated cone structure, the five parts form an inseparable horizontal set motion according to the gyroscopic mechanical structure, realizing a perfect combination of two main power lines 92, two rotating guide wheels and a central horseshoe structure tube 91, and completing the first layer of cabling process.

[0040] Embodiment 2:

[0041] On the basis of the first embodiment, the horseshoe shielded twisted structure 9 formed by the positioning and pressing is wrapped with aluminum foil on the outer layer on the cage stranding machine. The process of wrapping the cable with aluminum foil is a prior art and is not the main technical solution of this application. It is not described in detail here. The shielded horseshoe structure containing the horseshoe structure tube 91, two main power lines 92 and the shielded aluminum foil is pulled into the cable splitting device by a pulling device. The specific structure of the pulling device is as follows: Figure 5 As shown, the main structure of the device is composed of a horizontal line-laying load-bearing base 12, upper and lower locking clamps 10, a shaping fixture 2, locking bolts of the upper and lower locking clamps, and a locking center bearing stud.

[0042] Specifically, the horizontal line bearing base 12 adopts a diameter of The circular disk is provided with four hollow annular structures for easy installation and coordination of the center of gravity with the middle rectangular structure. The upper and lower locking clamps 10 are T-shaped structures and cooperate with each other to form the middle rectangular structure. The front end of the longitudinal rod of the T-shaped locking clamp 10 is fixed on the horizontal line-laying load-bearing base 12, and the shaping tool 2 is installed between the upper and lower cross plates at the front end of the rectangular locking structure. The shaping tool 2 here is substantially the same in structure as the shaping tool 2 in Example 1, except that the bearing guide column 201 is symmetrically inserted through the shaft seat of the cross plate of the locking clamp 10, and the two guide wheels 202 are respectively rotatably mounted on the two bearing guide columns 201 and are located between the upper and lower locking clamp cross plates. Locking bolts are installed on both sides of the locking clamp cross plate and on the locking clamp shaft seat to lock and fix the shaping tool 2.

[0043] The horseshoe structural member guide groove 203 of the shaping tool 2, the center line of the middle rectangular structural member and the horizontal line-laying load-bearing base 12 are coaxially arranged, and the middle rectangular structural member is designed as a horseshoe structural mother seat module, which allows the horseshoe shielded twisted structural member 9 wrapped with aluminum foil to pass through the mother seat module smoothly and quickly.

[0044] During specific use, the present invention is a cabling device for a liquid-cooled charging pile supercharging cable. After the first layer of cabling process, the horseshoe-shielded twisted structure 9 is wrapped with aluminum foil on the cage twisting machine and then enters the traction device. It passes through the central circular hole of the horizontal wire-laying load-bearing base 12 and the central guide groove of the front forming tooling 2. It is pulled forward by the rotation of the two guide wheels 202, and is extruded and shaped by the two guide wheels 202 to further position and shape the horseshoe-shielded twisted structure 9 wrapped with aluminum foil.

[0045] Embodiment three:

[0046] On the basis of Example 2, the horseshoe-shielded twisted structural member 9 that has undergone the above-mentioned first-layer process and has been pulled and positioned by the traction device enters the cabling and diversion device for the second-layer process. The cabling and diversion device includes a locking clamp 10, a horizontal wire-laying load-bearing base 12, a shaping tool 2, and a traction and introduction tool 1. The locking clamp 10, the horizontal wire-laying load-bearing base 12, and the shaping tool 2 of the cabling and diversion device have the same structure as the traction device in Example 2, and the traction and introduction tool 1 of the cabling and diversion device has the same structure as the traction and introduction tool 1 in Example 1, but the installation method is different. Specifically, the cable diversion device provided in this embodiment is formed by two upper and lower locking clamps 10 to form an intermediate rectangular structure, the shaping tooling 2 is installed in the rear end cross plate of the intermediate rectangular structure, the horizontal line-laying load-bearing base 12 is fixed to the front end of the intermediate rectangular structure, and the intermediate rectangular structure adopts a slide rail channel design. A slide rail channel 11 is opened on the longitudinal rod of the locking clamp 10 along the extension direction of the rod body. Positioning bolts 13 are provided on the upper and lower sides of the traction and introduction tooling 1 of this embodiment, and the positioning bolts 13 pass through the slide rail channel 11. The installation range of the traction and introduction tooling 1 in the cable diversion device is within the slide rail channel 11, and the traction and introduction tooling 1 of the second layer of the cable making process can be adjusted in pitch length and fine-tuned in positioning of the central structure, and locked and positioned by the positioning bolts 13. In addition, the upper and lower locking clamps 10 and the locking bolts of the upper and lower locking clamps and the locking bolts of the bearing guide column 201 can fully coordinate the central traction of the horseshoe shielded twisted structure 9 in the center of the cable. At the same time, the inner and outer shielding tapes and the signal lines and the control lines are positioned through the traction introduction tooling 1 of the cable diversion device and then pulled into the shaping tooling 2 of the cable diversion device together with the horseshoe shielded twisted structure 9, completing the tight twisting of the inner and outer shielding tapes and the signal lines and the control lines of the cage-twisted cable, thereby achieving consistent continuity of the centripetal force of the cable.

[0047] Embodiment 4:

[0048] On the basis of the above-mentioned embodiments, the structural parts of the device are all chamfered and polished with silky electroplating treatment at places where they pass through the horseshoe structure tube 91 and the main power line 92 guide wheel, so that the product will not be scratched, scraped or abraded in the fine process.

[0049] All porcelain threading holes 102 can be replaced with nano steel mold material threading holes, but the price is relatively expensive, and at the same time it is particularly wear-resistant and has a long service life; the material of the centralized introduction bakelite mold 8 is bakelite, which is a phenolic plastic, and can also be replaced with nylon. Both have very good wear resistance, but the high temperature resistance is slightly worse than bakelite. Considering indoor use, the impact is not obvious.

[0050] Embodiment five:

[0051] This embodiment provides a cabling process formed by the device provided in the above embodiments 1 to 4. The horseshoe structure tube 91 and the main power line 92 are the central components of the entire liquid-cooled supercharger charging cable, and are the heart operation center; the rotating guide wheel of the shaping tool 2 is the running bridge for positioning the running track of the main power line 92; the centralized introduction bakelite mold 8 is the tight hoop for shaping, sizing, and speeding of the first and second layers of processes, and the traction device and the cabling diversion device are the summary components of the shielding structure horseshoe structure tube 91 + main power line 92 + shielding belt and left and right locking guide wheel structure of the second layer of the assembly cabling process, which is the key tooling for the second layer of the assembly cabling process.

[0052] The first-layer cabling structure special-shaped device and the second-layer cabling structure special-shaped device provided in Example 1, Example 2 and Example 3 together constitute a liquid-cooled charging pile supercharging cable cabling process device, and the two are dependent on each other in the previous and next processes, complementing each other and indispensable. The first-layer cabling structure special-shaped device is the main structural component of the horseshoe pipe in the center of the cabling cable, and the second-layer cabling structure special-shaped device is the continuation of the first-layer cabling structure special-shaped device. The semi-finished product completed by the first-layer cabling structure special-shaped device is combined with the second-layer cabling structure special-shaped device to realize the cage-stranded assembly cabling process together with the peripheral 7 control wires, 2 pairs of signal wires, 2 red and black auxiliary ground wires, 1 yellow / green two-color main power ground wire, high-temperature single-sided aluminum foil, and Class D flame-retardant non-woven fabric, so as to achieve the unified functional goals of liquid-cooled supercharging cable structure size, mechanical and physical properties, electrical properties, and environmental resistance.

[0053] The above-mentioned special-shaped tooling and dies are self-contained and together complete the important process of special-shaped cabling of liquid-cooled charging pile cables. At the same time, the combination realizes the concentration of mechanical stress and centripetal force of the special-shaped cabling, achieving the necessary process elements for the entire liquid-cooled super charging cable swing test, low-temperature winding, and low-temperature tensile test.

[0054] According to the fact that the thermal conductivity of metals is greater than that of non-metals, the thermal conductivity of the solid phase of the material is greater than that of the liquid phase; at the same time, according to the thermal conduction, thermal convection and thermal radiation effects of the material, at room temperature, the thermal conductivity of copper alloy is greater than that of aluminum foil, the thermal conductivity of aluminum foil is greater than that of silicone rubber, and the thermal conductivity of silicone rubber is greater than that of silicone oil. Therefore, the application materials involved in this special-shaped process device mainly include: copper alloy, aluminum foil, silicone rubber, silicone oil. According to the law of heat conduction: the heat conduction rate is inversely proportional to the heat difference, and inversely proportional to the thermal conductivity and the heat transfer area. The comprehensive design of this structure gives full play to the maximum advantages of the thermal conduction area and thermal conduction rate of the material to complete the heat conduction efficiency between the liquid-cooled supercharging cable materials.

[0055] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
