Description

Technical Field

[0001] This invention relates to the field of cable processing technology, specifically to a torsion-resistant high-voltage, high-current liquid-cooled charging cable and its processing technology. Background Technology

[0002] The anti-torsion high-voltage, high-current liquid-cooled charging cable is a special cable designed specifically for super-fast charging of electric vehicles. Its core feature is that it uses internal circulating coolant to forcibly remove heat from the conductor, thereby significantly reducing the conductor diameter while carrying ultra-high currents of over 600A, making the cable lighter and more flexible. Structurally, it adopts special conductor stranding, elastic sheath, and anti-torsion coil design, which can withstand thousands of bends and drags without damage. It effectively solves the pain points of traditional charging cables that are prone to overheating, bulkiness, and twisting breakage during frequent use, and is a key technical guarantee for achieving high-power charging and a good user experience.

[0003] Currently, the connection sheaths of existing anti-torsion high-voltage high-current liquid-cooled charging cables cannot be positioned accurately during assembly due to manual docking. This prevents the cable from being properly connected and aligned during installation. Therefore, an improved device is needed to address these issues. Summary of the Invention

The second spring is fixedly installed between the first and second side plates, and the second spring is located on the outer ring of the rear guide rod. The displacement bracket is fixedly installed at the bottom end of the first side plate. The cover sleeve is adsorbed inside the side end of the displacement bracket away from the second side plate. The screw is threaded into the outside of the cover sleeve. The limiting bracket is symmetrically fixedly installed at the side end of the displacement bracket. The contact crossbar is fixedly installed at the top end of the first side plate away from the rack. The lower edge bracket is fixedly installed at the bottom end of the second side plate away from the rack. The contact sensor is fixedly installed at the top end of the second side plate near the lower edge bracket.

[0009] Specifically, the synchronization device includes a shaped connecting plate, a first piston rod, an L-shaped air cylinder, a second piston rod, a synchronization side frame, and a contact guide plate. The first piston rod is slidably inserted into one end of the L-shaped air cylinder. The shaped connecting plate is fixedly installed on the side of the first piston rod away from the L-shaped air cylinder. The second piston rod is slidably inserted into the other end of the L-shaped air cylinder. The synchronization side frame is fixedly installed on the side of the second piston rod away from the L-shaped air cylinder. The contact guide plate is fixedly installed on the bottom end of the synchronization side frame away from the second piston rod.

[0010] Specifically, guide columns are symmetrically fixedly installed at the bottom inner end of the support base, and positioning side plates are symmetrically fixedly installed at the bottom inner end of the support base, with the positioning side plates located above the guide columns. An extended arc sleeve is fixedly installed on the outer side of the positioning side plates. A support top frame is fixedly installed at the top of the support base away from the guide columns, and a drive motor is fixedly installed at the top of the support top frame. A transmission gear is fixedly installed at the bottom end of the drive motor.

[0011] Specifically, the L-shaped air cylinder is fixedly installed at both ends inside the support top frame, the end of the irregular connecting plate away from the first piston rod is connected to the top of the rack, the small motor is fixedly installed at the bottom of the lower edge bracket, the bottom end of the displacement bracket is slidably sleeved on the outer ring of the guide base column, and the rack meshes with the transmission gear.

[0012] Specifically, the L-shaped air cylinder is hollow inside, and a sealed cavity is formed between the first piston rod, the L-shaped air cylinder, and the second piston rod. The contact sensor is electrically connected to a small motor, and the contact sensor is vertically aligned with the contact bar.

[0013] Specifically, a magnetic suction plate is fixedly installed on the inner side of the displacement bracket, and an iron plate is fixedly installed on the outer side of the cover sleeve. The screw and the cross key are horizontally aligned. The contact guide plate is aligned with the inside of the extended arc sleeve, and the contact guide plate is attached to the side end of the positioning side plate.

[0014] A processing technology for a torsion-resistant high-voltage, high-current liquid-cooled charging cable processing equipment includes the following steps:

[0015] S1. First, insert the charging gun head into the socket built into the support base, and then place the cable sheath on the placement seat at the top of the support base so that the connection area between the cable sheath and the charging gun head can be placed stably.

[0016] S2. Then, the drive motor can be turned on to drive the transmission gear to rotate. When the transmission gear rotates, it can drive the rack to move, so that the cover sleeve can move to fit with the junction of the cable sheath and the charging gun head, so that the two cover sleeves can cover the junction of the cable sheath and the charging gun head. Then, through the setting of the second spring, the second side plate can continuously move, the cross key can contact the screw, and the contact sensor can contact the contact bar to start the small motor. Then the cross key can rotate the screw into the inside of the side frame, so that the two cover sleeves can be installed on the cable sheath and the charging gun head.

[0017] S3. Finally, the drive motor is turned on, causing the transmission gear to rotate in the opposite direction. This allows the rack to move the displacement bracket away from the cable sheath, disengaging it from the cable sheath. When the rack returns to its original position, the first piston rod enters the L-shaped air cylinder, allowing the contact guide plate to move. The contact guide plate then pushes the cover sleeve, placed between the positioning side plate and the extended arc sleeve, into the displacement bracket until the cover sleeve is stably attracted and restrained by the displacement bracket, completing the replacement of the cover sleeve.

[0018] The beneficial effects of this invention are:

[0019] First, this invention, when the drive motor is running, can drive two racks to move via transmission gears, allowing the displacement bracket to move the cover sleeve to the junction with the cable sheath and charging gun head. Simultaneously, the second spring allows the second side plate to continuously move, enabling the cross key to move to contact the screw, and the contact sensor to move to contact the contact bar. When the small motor is started and the cross key rotates, the screw can be installed into the side frame and the cover sleeve. When the contact sensor moves out from the top of the contact bar, the small motor can be de-energized, avoiding prolonged operation of the small motor and completing the cover sleeve delivery and docking work.

[0020] Second, in this invention, when the rack moves in the reverse direction, it can align the recessed part inside the displacement bracket with the extended arc sleeve. At the same time, the displacement bracket can be positioned in advance. When the rack moves to the limit position, the irregular connecting plate can drive the first piston rod to be fully inserted into the L-shaped air cylinder, so that the second piston rod can drive the contact guide plate to be inserted into the extended arc sleeve. By placing the cover sleeve inside the extended arc sleeve in advance, the contact guide plate can push the cover sleeve out from the inside of the extended arc sleeve when it moves. At the same time, by the side of the extended arc sleeve away from the support top frame and the side of the displacement bracket, the contact guide plate can accurately push the cover sleeve into the inside of the displacement bracket. The magnetic absorbing piece inside the displacement bracket attracts the cover sleeve, completing the alignment and replenishment of the cover sleeve. Attached Figure Description

The synchronization side frame 34 is fixedly installed on the side of the second piston rod 33 away from the L-shaped air cylinder 32. The contact guide plate 35 is fixedly installed on the bottom end of the synchronization side frame 34 away from the second piston rod 33. By separating the shaped connecting plate 30 and the first piston rod 31, the shaped connecting plate 30 can be separated from the first piston rod 31.

[0038] like Figure 8 The support base 2 has guide columns 40 symmetrically fixedly installed at its inner bottom end, and positioning side plates 41 symmetrically fixedly installed at its inner bottom end, with the positioning side plates 41 located above the guide columns 40. An extended arc sleeve 39 is fixedly installed on the outer side of the positioning side plates 41. A support top frame 38 is fixedly installed at the top of the support base 2 away from the guide columns 40. A drive motor 37 is fixedly installed at the top of the support top frame 38, and a transmission gear 36 is fixedly installed at the bottom of the drive motor 37.

The bottom end of the displacement bracket 21 is slidably sleeved on the outer ring of the guide base column 40. The rack 18 meshes with the transmission gear 36. The interior of the L-shaped air cylinder 32 is hollow. A sealed cavity is formed between the first piston rod 31, the L-shaped air cylinder 32 and the second piston rod 33.

The contact guide plate 35 is attached to the side end of the positioning side plate 41.

[0040] A processing technology for a torsion-resistant high-voltage, high-current liquid-cooled charging cable processing equipment includes the following steps:

[0041] S1. First, insert the charging gun head 3 into the socket built into the support base 2, and then place the cable sheath 1 on the placement seat at the top of the support base 2 so that the connection area between the cable sheath 1 and the charging gun head 3 can be placed stably.

[0042] S2. Then, the drive motor 37 can be turned on to drive the transmission gear 36 to rotate. When the transmission gear 36 rotates, it can drive the rack 18 to move, so that the cover sleeve 22 can move to fit with the junction of the cable sheath 1 and the charging gun head 3, so that the two cover sleeves 22 can cover the junction of the cable sheath 1 and the charging gun head 3. Subsequently, through the setting of the second spring 19, the second side plate 29 can continuously move, the cross key 15 can contact the screw 23, and the contact sensor 27 can contact the contact bar 25 to start the small motor 12. Then the cross key 15 can rotate the screw 23 into the inside of the side frame 4, and the two cover sleeves 22 can be installed on the cable sheath 1 and the charging gun head 3.

[0043] S3. Finally, the drive motor 37 is turned on, driving the transmission gear 36 to rotate in the opposite direction, so that the rack 18 can drive the displacement bracket 21 to move away from the cable sheath 1, so that the displacement bracket 21 can disengage from the cable sheath 1. When the rack 18 is reset, the first piston rod 31 can enter the interior of the L-shaped air cylinder 32, so that the contact guide plate 35 can move. Then the contact guide plate 35 can push the cover sleeve 22 placed between the positioning side plate 41 and the extended arc sleeve 39 to move into the interior of the displacement bracket 21, until the cover sleeve 22 can be stably attracted and restricted by the displacement bracket 21, completing the replenishment of the cover sleeve 22.

[0044] The working principle is as follows: In use, first install the charging gun head 3 into the socket built into the support base 2, so that the area where the charging gun head 3 and the cable sheath 1 meet is horizontally aligned with the displacement bracket 21. Then, turn on the drive motor 37 to drive the transmission gear 36 to rotate. When the transmission gear 36 rotates, it drives the two racks 18 to move simultaneously towards the cable sheath 1. At this time, the racks 18 can drive the second side plate 29 and the first side plate 20 to move synchronously. The bottom end of the displacement bracket 21 slides onto the outer ring of the guide column 40, allowing the displacement bracket 21 to move linearly until the displacement bracket 21 drives the internal covering sleeve 22 to move and fit onto the surface at the junction of the cable sheath 1 and the charging gun head 3. Then, the second spring... Spring 19 is installed between the first side plate 20 and the second side plate 29, allowing the second side plate 29 to continuously move towards the cable sheath 1. At this time, the second side plate 29 is slidably sleeved on the outer ring of the rear guide rod 28, supporting its linear movement. When the second side plate 29 moves, it drives the contact sensor 27 to move along the surface of the contact bar 25. The contact sensor 27 is electrically connected to the miniature motor 12. When the contact sensor 27 senses a signal from the contact bar 25, it activates the miniature motor 12. The shaft inside the miniature motor 12 is connected to the first disk 13, allowing the miniature motor 12 to drive the first disk 13 to rotate. When the first disk 13 rotates, it can be driven by the guide rod 17... Simultaneously, the cross key 15 rotates, at which point it can contact the screw 23. When the cross key 15 rotates, it can drive the screw 23 to be screwed into the threaded hole inside the cover sleeve 22 and the side frame 4. Furthermore, the elasticity of the first spring 16 can always apply pressure to the cross key 15, making it easy for the cross key 15 to squeeze the screw 23 into the inside of the side frame 4. When the screw 23 is completely screwed into the inside of the side frame 4, the work of installing the cover sleeve 22 into the junction area of ​​the cable sheath 1 and the charging gun head 3 is completed. Subsequently, the new cover sleeve 22 can be moved and placed inside the extended arc sleeve 39. Then, the drive motor 37 is turned on, driving the transmission gear 36 to rotate in the opposite direction. At this time, the rack 18 can be moved and reset, driving the second side plate 29 to pull the first through the second spring 19. After the side plate 20 moves and resets, and the displacement bracket 21 moves to the point where it disengages from the cable sheath 1, the displacement bracket 21 can move to its limit position on the guide column 40. When the displacement bracket 21 moves to its limit position away from the cable sheath 1, the arc groove inside the displacement bracket 21 can align with the extended arc sleeve 39. Subsequently, as the second side plate 29 continues to move towards the rear end, it can cause the contact sensor 27 to disengage from the contact bar 25. At the same time, the small motor 12 can be de-energized. The second side plate 29 can drive the irregular connecting plate 30 to move to contact the first piston rod 31 through the rack 18, thereby pushing the first piston rod 31 into the interior of the L-shaped air cylinder 32. At this time, the second piston rod 33 can move away from the L-shaped air cylinder 32.The synchronous side frame 34 can drive the contact guide plate 35 into the interior of the extended arc sleeve 39, so that the contact guide plate 35 can push the cover sleeve 22 inside the extended arc sleeve 39 into the interior of the displacement bracket 21. A metal plate is fixedly installed on the outer ring of the cover sleeve 22, and a magnetic plate is installed in the arc groove on the inner side of the displacement bracket 21, so that the cover sleeve 22 can be attracted and fixed by the magnetic plate inside the displacement bracket 21 through the metal plate, completing the replenishment of the cover sleeve 22. Subsequently, when the rack 18 moves again towards the cable sheath 1, it is magnetically attracted and attached to the irregular connecting plate 30 by the first piston rod 31, so that the irregular connecting plate 30 can drive the first piston rod 31 to move towards the cable sheath 1. The piston rod 31 is drawn from inside the L-shaped air cylinder 32, thereby resetting the second piston rod 33. This causes the contact guide plate 35 to be pulled out from inside the extended arc sleeve 39, facilitating the repositioning of the cover sleeve 22 inside the extended arc sleeve 39. After the contact guide plate 35 is fully reset, the rack 18 can drive the irregular connecting plate 30 to disengage from the first piston rod 31, completing the operation. The coolant is interconnected with the flow guide hose 5 via the delivery pipe 6, and the two flow guide hoses 5 serve as the delivery and return hoses, respectively, allowing the coolant to circulate between the flow guide hose 5 and the delivery pipe 6. Furthermore, the delivery pipe 6 contacts the flow guide hose 5, enabling the coolant to cool the cable core 7.
