[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, a dual-channel component is added to the cooling box port, and the coolant enters the first inlet and the second inlet respectively from the two branch pipes of the dual-branch pipe, wherein the coolant entering the first inlet flows into the inner cavity of the end pipe, and then enters the inner cavity of the built-in pipe, and is filled into the cooling box of the hybrid vehicle from multiple liquid outlets. At this time, the coolant entering the second inlet flows into the inner cavity of the ring pipe, passes through the multi-component groove, and flows into the interior of the inner oblique pipe. There is a gap between the built-in pipe and the inner oblique pipe, and the coolant is filled into the cooling box of the hybrid vehicle from the gap, realizing dual-channel filling and improving the filling speed. In the early stage of coolant filling, the end pipe is pressed heavily. At this time, the coolant is filled into the coolant tank from the multiple liquid outlets and the gap between the built-in pipe and the inner oblique pipe, realizing dual-channel rapid filling. In the later stage of filling, the end pipe is pressed lightly, and the middle part of the built-in pipe gradually overlaps with a part of the second inlet. At this time, the flow rate in the gap between the built-in pipe and the inner oblique pipe decreases, and the filling speed decreases, which is convenient for the staff to carry out finishing work and avoids overflow of coolant due to excessive filling.

[0020] 2. In the present invention, the turbine rod portion in the worm gear box is extended and connected to the coolant delivery mechanism, the turbine shaft portion in the worm gear box is extended and fixed to the spiral delivery ring, and a group of power drives the coolant delivery mechanism and the spiral delivery ring to rotate respectively to realize linkage. While pressing the end tube, the stepper motor is started and drives the turbine and worm in the worm gear box to rotate. When the turbine rotates, it drives the spiral delivery ring to rotate in the cylindrical tube. With the help of the spiral delivery ring, the coolant stored in the conical bin is accelerated from the conical bin into the cylindrical tube and then into the input steel pipe. When the spiral delivery ring rotates, it also drives the inner scraper to perform a conical pendulum motion on the inner wall of the conical bin to scrape off the remaining coolant on the inner wall of the conical bin to prevent coolant residue. When the worm rotates, it drives the first helical gear to rotate inside the outer shell. The first helical gear The meshing second helical gear member rotates inside the outer shell, and then the first helical gear member drives the first rotor to rotate while the second helical gear member drives the second rotor to rotate. The rotation direction of the second helical gear member is opposite to the rotation direction of the first helical gear member, so the first rotor and the second rotor rotate synchronously in opposite directions. During the rotation process, suction, that is, negative pressure, is generated at the connection position of the outer shell and the mounting frame, so that the coolant inside the input steel pipe is sucked into the inner cavity of the outer shell. During the process of synchronous reverse rotation of the first rotor and the second rotor, the coolant is pushed into the output pipe assembly at the connection port of the outer shell and the output pipe assembly. The first rotor and the second rotor, which rotate at high speed, rotate in opposite directions in this cycle, and serve as the power for coolant output to replace the compressed air output power, thereby avoiding the dilution of the coolant by moisture and liquid in the compressed air, thereby ensuring the cooling effect of the coolant.

[0021] 3. In the present invention, an inner screw cap is added to the opening of the cooling box, the dual-channel assembly is removed from the pipe rack, and vertically inserted into the opening of the cooling box. The inner screw cap is rotated to engage the outer thread of the cooling box, thereby fixing the dual-channel assembly to the cooling box, freeing the operator's hands and eliminating the need for the operator to hold the filling port, making it more convenient for the operator to control the filling.

[0035] One side of the outer shell 34 is fixedly connected to an output pipe assembly 51, and the other end of the output pipe assembly 51 is fixedly connected to a dual-channel assembly 52. ​​The dual-channel assembly 52 includes an end pipe 521, an interior of the end pipe 521 is provided with a first inlet 522, the lower end of the end pipe 521 is threadedly connected to an inner pipe 524, a spring 523 is partially sleeved on the outer surface of the inner pipe 524, a ring pipe 525 is movably connected to the middle of the outer surface of the inner pipe 524, a second inlet 526 is provided inside the ring pipe 525, and the outer side of the inner pipe 524 is provided with a multi-component groove 5 27. The lower portion of the outer surface of the built-in tube 524 is movably connected to an inner oblique tube 528, the upper side of the inner oblique tube 528 is fixedly connected to the lower side of the ring tube 525, the outer side of the ring tube 525 and the outer side of the inner oblique tube 528 are rotatably connected with an inner screw cover 529, the lower end of the built-in tube 524 is provided with multiple groups of liquid outlets 530, the inner wall of the first inlet 522 and the inner wall of the second inlet 526 are fixedly connected with a double branch tube 516, the upper end of the spring 523 is fixedly connected to the lower side of the end tube 521, and the lower end of the spring 523 is fixedly connected to the upper side of the ring tube 525.

[0036] In this embodiment, by providing a dual-channel component 52, the coolant enters the first inlet 522 and the second inlet 526 from the two branch pipes of the dual-branch pipe 516 respectively. The coolant entering the first inlet 522 flows into the inner cavity of the end pipe 521, and then enters the inner cavity of the built-in pipe 524, and is filled into the hybrid vehicle cooling box from multiple liquid outlets 530. At this time, the coolant entering the second inlet 526 flows into the inner cavity of the ring pipe 525, passes through the multi-component groove 527, and flows into the inner oblique pipe 528. There is a gap between the built-in pipe 524 and the inner oblique pipe 528, and the coolant is filled into the hybrid vehicle cooling box through the gap, realizing dual-channel filling and improving the filling speed. When the end pipe 521 is lightly pressed, the middle part of the built-in pipe 524 overlaps half with the second inlet 526.

At this time, the flow rate in the second inlet 526 is the same as the flow rate of the first inlet 522. In the early stage of coolant filling, the end tube 521 is pressed heavily. At this time, the coolant is filled into the coolant tank from multiple liquid outlets 530 and the gap between the built-in tube 524 and the inner oblique tube 528, realizing dual-channel rapid filling. In the later stage of filling, the end tube 521 is pressed lightly, and the middle part of the built-in tube 524 gradually overlaps with a part of the second inlet 526. At this time, the flow rate in the gap between the built-in tube 524 and the inner oblique tube 528 decreases, and the filling speed decreases, which is convenient for the staff to carry out finishing work and avoid overflow due to excessive coolant filling. Example

[0037] according to Figure 4-6 As shown, the other end of the double-branch pipe 516 is fixedly connected to a connecting hose 515, which is sleeved on the inside of the pipe rack 4. The other end of the connecting hose 515 is fixedly connected to a flow meter 514, and the lower side of the flow meter 514 is fixedly connected to a support plate 513. The lower side of the support plate 513 is fixedly connected to the inside of the mobile frame 1. The other end of the flow meter 514 is fixedly connected to a valve 512, and the other end of the valve 512 is fixedly connected to an output steel pipe 511. The other end of the output steel pipe 511 is fixedly connected to one side of the outer shell 34.

[0038] In this embodiment, by providing an output pipe assembly 51, the connecting hose 515 is wrapped around the inside of the pipe rack 4, which facilitates the storage of the connecting hose 515. At the same time, the connecting hose 515 has a certain length, which improves the scope of use. The coolant inside the output pipe assembly 51 is forced to enter the valve 512, the flow meter 514 and the connecting hose 515 in sequence. The coolant flow rate of the flow meter 514 is observed, and the valve 512 acts as a valve to control the coolant flow rate. The coolant in the connecting hose 515 is input into the double branch pipe 516, and enters the first inlet 522 and the second inlet 526 from the two branches of the double branch pipe 516 respectively to achieve subsequent filling. Example

[0039] according to Figure 1-6 As shown, the other side of the outer shell 34 is fixedly connected to the input steel pipe 32, the inner side of the outer shell 34 is rotatably connected to the shaft of the first helical gear member 33 and the shaft of the second helical gear member 36, the lower side of the outer shell 34 is fixedly connected to the mounting bracket 31 by bolts, the lower side of the mounting bracket 31 is fixedly connected to the interior of the mobile frame 1, the other end of the worm of the worm gear box 25 is fixedly connected to the stepping motor 26, one end of the turbine shaft of the worm gear box 25 is fixedly connected to the spiral conveying ring 23, the worm gear box 2 5 is fixedly connected to the upper side of the cylindrical tube 24, the spiral conveying ring 23 is located in the inner cavity of the cylindrical tube 24, the outer side of the cylindrical tube 24 is fixedly connected to the other end of the input steel pipe 32, the lower side of the turbine worm box 25 is fixedly installed with the interior of the mobile frame 1, the upper end of the spiral conveying ring 23 is fixedly connected to the inner scraper 22, the upper side of the cylindrical tube 24 is fixedly connected to the conical bin 21, the inner wall of the conical bin 21 is movably connected to one side of the inner scraper 22, and the outer side of the conical bin 21 is fixedly connected to the interior of the mobile frame 1.

[0040] In this embodiment, the turbine rod portion in the worm gear box 25 is extended and connected to the coolant delivery mechanism 3, and the turbine shaft portion in the worm gear box 25 is extended and fixed to the spiral delivery ring 23. A group of power drives the coolant delivery mechanism 3 and the spiral delivery ring 23 to rotate respectively, realizing linkage. While pressing the end tube 521, the stepper motor 26 is started, and the turbine and worm in the worm gear box 25 are driven to rotate. When the turbine rotates, the spiral delivery ring 23 is driven to rotate in the cylindrical tube 24. With the help of the spiral delivery ring 23, the coolant stored in the conical bin 21 is accelerated from the conical bin 21 into the cylindrical tube 24 and then into the input steel pipe 32. When the spiral delivery ring 23 rotates, it also drives the inner scraper 22 to perform a conical pendulum motion on the inner wall of the conical bin 21, scraping off the coolant remaining on the inner wall of the conical bin 21 to prevent coolant from remaining. When the worm rotates, it drives the first helical gear 33 to rotate inside the outer shell 34. The first helical gear 3 The meshing second helical gear 36 rotates inside the outer shell 34, and the first helical gear 33 drives the first rotor 35 to rotate while the second helical gear 36 drives the second rotor 37 to rotate. The rotation direction of the second helical gear 36 is opposite to that of the first helical gear 33, so the first rotor 35 and the second rotor 37 rotate synchronously in opposite directions. During the rotation process, suction, i.e., negative pressure, is generated at the connection between the outer shell 34 and the mounting frame 31, causing the coolant inside the input steel pipe 32 to be sucked into the inner cavity of the outer shell 34. During the synchronous counter-rotation of the first rotor 35 and the second rotor 37, the coolant is pushed into the output pipe assembly 51 at the connection between the outer shell 34 and the output pipe assembly 51. The high-speed rotating first rotor 35 and the second rotor 37 rotate in opposite directions in this cycle, which serves as the power output by the coolant, replacing the power output by the compressed air, preventing the moisture and liquid in the compressed air from diluting the coolant, thereby ensuring the cooling effect of the coolant.

[0041] The method of use and working principle of this device are as follows: When using the hybrid thermal management coolant rapid filling machine, first push the filling machine near the hybrid vehicle, unscrew the cooling box cover of the hybrid vehicle, remove the dual-channel assembly 52 from the pipe rack 4, vertically insert it into the cooling box opening, rotate the inner screw cap 529 so that it is locked on the external thread of the cooling box, and thus fix the dual-channel assembly 52 to the cooling box;

[0042] Next, the end tube 521 is lightly pressed downward, and the end tube 521 pushes the inner tube 524 downward, and the inner tube 524 slides downward inside the ring tube 525, and the lower end of the inner tube 524 extends from the inner wall of the inner oblique tube 528, thereby exposing the liquid outlet 530 from the inner oblique tube 528. While pressing the end tube 521, the stepper motor 26 is started, the valve 512 is opened, and the stepper motor 26 injects power into the worm gear box 25, driving the worm and the worm in the worm gear box 25 to rotate. When the worm rotates, the spiral conveying ring 23 is driven to rotate in the cylindrical tube 24. With the help of the spiral conveying ring 23, the coolant stored in the conical bin 21 is accelerated from the conical bin 21 into the cylindrical tube 24 and then into the input steel pipe 32. While the spiral conveying ring 23 rotates, it also drives the inner scraper 22 to perform a conical pendulum motion on the inner wall of the conical bin 21, scraping off the remaining coolant on the inner wall of the conical bin 21.

[0043] When the worm rotates, it drives the first helical gear 33 to rotate inside the outer shell 34. The first helical gear 33 meshes with the second helical gear 36 to rotate inside the outer shell 34. Then, the first helical gear 33 drives the first rotor 35 to rotate while the second helical gear 36 drives the second rotor 37 to rotate. The direction of rotation of the second helical gear 36 is opposite to that of the first helical gear 33. Therefore, the first rotor 35 and the second rotor 37 rotate synchronously in opposite directions. During the rotation process, suction, that is, negative pressure, is generated at the connection position between the outer shell 34 and the mounting frame 31, so that the coolant inside the input steel pipe 32 is sucked into the inner cavity of the outer shell 34. During the process of synchronous counter-rotation of the first rotor 35 and the second rotor 37, the coolant is pushed into the output pipe assembly 51 at the connection position between the outer shell 34 and the output pipe assembly 51. The first rotor 35 and the second rotor 37, which rotate at high speed, rotate in opposite directions in this cycle, which serves as the power for the coolant output.

[0044] The coolant in the output pipe assembly 51 is forced to enter the valve 512, the flow meter 514 and the connecting hose 515 in sequence. The coolant flow rate is observed on the flow meter 514, and the valve 512 acts as a valve to control the coolant flow rate. The coolant in the connecting hose 515 is input into the double branch pipe 516, and then enters the first inlet 522 and the second inlet 526 from the two branches of the double branch pipe 516 respectively.

[0045] The coolant entering the first inlet 522 flows into the inner cavity of the end tube 521, and then into the inner cavity of the built-in tube 524, and is filled into the hybrid vehicle cooling box from multiple liquid outlets 530. At this time, the coolant entering the second inlet 526 flows into the inner cavity of the ring tube 525, passes through the multi-component groove 527, and flows into the inner inclined tube 528. There is a gap between the built-in tube 524 and the inner inclined tube 528, and the coolant is filled into the hybrid vehicle cooling box through the gap, realizing dual-channel filling. When the end tube 521 is lightly pressed, the middle part of the built-in tube 524 overlaps half with the second inlet 526. At this time, the flow rate in the second inlet 526 is half of the flow rate of the first inlet 522, and when the end tube is pressed heavily, the coolant in the second inlet 526 is half of the flow rate of the first inlet 522. After 521, the middle part of the built-in tube 524 is completely located below the second inlet 526, and the second inlet 526 is in a fully open state. At this time, the flow rate in the second inlet 526 is the same as the flow rate in the first inlet 522. In the early stage of coolant filling, the end tube 521 is pressed heavily. At this time, the coolant is filled into the coolant tank from multiple liquid outlets 530 and the gap between the built-in tube 524 and the inner oblique tube 528, realizing dual-channel rapid filling. In the later stage of filling, the end tube 521 is pressed lightly. The middle part of the built-in tube 524 gradually overlaps with a part of the second inlet 526. At this time, the flow rate in the gap between the built-in tube 524 and the inner oblique tube 528 decreases, and the filling speed decreases. After the end tube 521 is completely released, the filling stops.

[0046] After the filling is completed, unscrew the inner screw cap 529 and screw on the cooling box cover to complete the filling of the coolant.
