Description

Technical Field

[0001] The invention belongs to the technical field of new energy vehicle charging equipment, and specifically is an emergency new energy vehicle charging device. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional As source (or use conventional vehicle fuel, adopt new vehicle power device), comprehensive vehicle power control and The new energy vehicle charging pile is a device that provides electrical energy to electric vehicles, enabling them to store enough electricity to support their operation.

[0003] The patent with announcement number CN109624761B discloses an emergency charging auxiliary device for new energy vehicles, including a charging pile, a charging cable and a charging gun connected to the charging pile through the charging cable. The bottom side of the charging pile is fixedly connected to a base, and universal wheels are installed at the four bottom corners of the base. First grooves are opened on both sides of the base, and mounting holes are opened on the bottom inner wall of the first groove. A support plate is movably installed in the mounting hole. The top side of the support plate extends into the corresponding first groove, and a first rotating hole is opened on the top of the side where the two support plates are close to each other. The same first rotating shaft is welded on the inner walls of both sides of the first groove. The patent has a reasonable design and can switch the support mode of the base at any time. When the universal wheels on the base are in contact with the ground, it is convenient to move the position of the charging pile. When the support plate on the base is in contact with the ground, the stability of the entire device is increased, which is convenient for people to use.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] By setting universal wheels at the bottom of the charging pile, when the new energy vehicle is out of power and cannot be moved to the vicinity of the charging pile, the universal wheels are used to move the charging pile to the vicinity of the new energy vehicle to charge the new energy vehicle. Although this method can be used to charge the new energy vehicle without moving it, when the charging pile is used as a public equipment, it is necessary to move the charging pile back to the initial position after charging is completed. Since the charging pile has a certain weight, the entire moving process is relatively laborious. In addition, in some cases, two charging guns are set on the charging pile, which can charge two new energy vehicles at the same time to improve efficiency. When the charging pile is moved to the vicinity of the new energy vehicle that needs to be charged, the other charging gun will be unable to charge other new energy vehicles, thereby affecting the charging efficiency.

It has high safety. Moreover, when the two charging cables are wound up at the same time and entangled with each other, the two charging cables can be separated. This not only ensures the subsequent normal use of the charging gun, but also avoids the situation that the two charging cables are damaged due to stretching because the two charging cables are tightly wound and the winding disk continues to rotate, further improving the safety. Moreover, during the separation of the two charging cables, when the clamping plate no longer clamps the charging gun, the lower pressure rod can be driven down. If the two charging cables are still slightly entangled, the lower pressure rod will push the angle formed by the entanglement of the two charging cables to completely separate the two charging cables, thereby preventing the situation that the charging cables are still slightly entangled after the clamping plate is away from the charging gun, and the two charging cables are tightened and cannot be separated again when the winding disk winds up the charging cables.

The front end of the sliding rod 29 is fixedly connected to the mounting seat 12, and two connecting rods 14 are rotatably provided on the front and rear sides of the mounting seat 12. A connecting rod 15 is rotatably provided on one end of the connecting rod 14, and a fixed disk 17 is rotatably provided on one end of the connecting rod 15. A rotating rod 18 is rotatably provided on the middle part of the upper end surface of the fixed disk 17, and a tray 19 is fixedly connected to the upper end of the rotating rod 18.

[0041] An electric push rod 28 is fixedly connected to one side of the rear end surface of the support plate 27, and the piston end of the electric push rod 28 is fixedly connected to one side of the rear end surface of the mounting seat 12. Motor 2 13 is fixedly connected to one side of the mounting seat 12, and the output end of motor 2 13 is fixedly connected to one end of connecting rod 14. Motor 3 16 is fixedly connected to the middle part of the lower end surface of the fixed plate 17, and the output end of motor 3 16 is fixedly connected to the bottom of the rotating rod 18.

[0042] A spring 22 is sleeved on one side of the slide post 21 . One end of the spring 22 is fixedly connected to the slide plate 20 , and the other end of the spring 22 is fixedly connected to one side of the clamping plate 38 .

[0043] Specifically, when the existing new energy vehicle charging pile is in use, a universal wheel 3 is arranged at the bottom of the charging pile 1. When the new energy vehicle is out of power and cannot be moved to the vicinity of the charging pile 1, the universal wheel 3 is used to move the charging pile 1 to the vicinity of the new energy vehicle to charge the new energy vehicle. Although this method can be used to charge the new energy vehicle without moving the new energy vehicle, when the charging pile 1 is used as a public device, the charging pile 1 needs to be moved back to the initial position after charging is completed. Since the charging pile 1 has a certain weight, the entire moving process is relatively laborious. In addition, in some cases, two charging guns 6 are arranged on the charging pile 1, which can charge two new energy vehicles at the same time to improve efficiency. When the charging pile 1 is moved to the vicinity of the new energy vehicle that needs to be charged, the other charging gun 6 will be unable to charge other new energy vehicles, thereby affecting the charging efficiency.

[0044] Therefore, in order to avoid the above problems, when the present embodiment is in use, when the new energy vehicle cannot be moved near the charging pile 1, the personnel can hold the charging gun 6 and use the motor 5 25 to drive the winding disk 26 to rotate, and the winding disk 26 unwinds the charging line 4. At the same time, the personnel can carry the charging gun 6 to the side of the car, and use the charging gun 6 to charge the car, thereby eliminating the process of moving the charging pile 1 back and forth, which is more labor-saving. At the same time, the other charging gun 6 can also perform the charging work, thereby improving the charging efficiency.

[0045] When charging is finished, since the charging line 4 may be unwound for a long time, if the personnel carry the charging gun 6 back to the charging pile 1, they need to walk a long distance, which is troublesome. If the charging line 4 is reeled in, the charging gun 6 will slide on the ground, which is easy to damage the charging gun 6. Therefore, in order to avoid this situation, after charging is finished, the motor 8 can be used to drive the fan wheel 35 on one side to rotate, and the two protective shells 9 can be driven by the two fan wheels 35 to rotate in different directions at the same time. When the two protective shells 9 are in contact, the charging gun 6 is covered. At this time, the personnel can put down the charging gun 6. When the charging gun 6 falls, the protective shell 9 will protect the charging gun 6. During the whole reeling process, the charging gun 6 will not directly contact the ground until the charging gun 6 is suspended again, the two protective shells 9 are separated, and the connecting handle 7 of the charging gun 6 is in contact with the bottom of the blocking block 36, thereby eliminating the process of the personnel carrying the charging gun 6 to reset to the original position, which is more convenient. At the same time, it also avoids the situation that the charging gun 6 is damaged due to contact and friction with the ground when the charging gun 6 is automatically reset, and the safety is high.

[0046] Since there are two charging guns 6, when the two charging guns 6 are reset at the same time, the two charging cables 4 may be entangled due to external forces and other factors, which not only affects the subsequent use, but also, when the two charging cables 4 are tightly wound, if the winding disk 26 continues to rotate, the two charging cables 4 will be damaged due to stretching. Therefore, in order to avoid this situation, when the charging cable 4 is wound and unwound, the tension of the charging cable 4 can be detected by the three-pulley tension sensor 11. The three-pulley tension sensor 11 is provided with a force-bearing wheel and two positioning wheels. The charging cable 4 passes through the gap between the force-bearing wheel and the positioning wheel, and fits with the surface of the positioning wheel and the force-bearing wheel. When the charging cable 4 moves, the tension of the charging cable 4 can be monitored in real time. The above monitoring process is a prior art and will not be described in detail.If the charging cable 4 is not entangled, the tension value of the charging cable 4 monitored by the three-pulley tension sensor 11 is within a reasonable range. When the charging cable 4 is entangled, if the two charging guns 6 are still resetting at this time, since the shell 5 is in contact with the ground, the ground provides support for the shell 5. Therefore, even if the charging cable 4 is entangled at this time, the tension is within a normal range. When the charging gun 6 moves to the front of the charging pile 1 and is suspended in the air, if the winding cannot separate the two charging cables 4, the connecting handle 7 at the end of the charging gun 6 will not contact the blocking block 36. At this time, the winding will only stretch the two charging cables 4, and the tension of the charging cable 4 monitored by the three-pulley tension sensor 11 gradually increases. Trend, at this time, the winding disk 26 stops rotating, and the charging line 4 is no longer wound, then the motor six 30 drives the threaded rod one 32 to rotate, so that the baffle 31 moves laterally and no longer covers the extension port 37. At this time, the electric push rod 28 can be used to drive the mounting seat 12 to extend from the inner cavity of the charging pile 1, and then the motor two 13 is used to drive the connecting rod one 14 and the connecting rod two 15 to rotate, so that the tray 19 rises. When the tray 19 contacts the suspended charging gun 6 and provides support for the charging gun 6, the charging line 4 will be slightly relaxed because the charging gun 6 is supported. At this time, the tension detected by the three-pulley tension sensor 11 will become smaller. When the tension becomes smaller, the tray 19 will stop rising, and then the motor four 23 is used to drive the two-way The threaded rod 24 rotates to bring the two slide plates 20 closer to each other. Since the two charging guns 6 are also fitted together when the charging line 4 is wound, the two clamping plates 38 can be used to clamp the two charging guns 6. At the same time, under the action of the slide column 21 and the spring 22, the charging gun 6 also has a buffering effect to prevent the charging gun 6 from being damaged. When the two charging guns 6 are clamped, the motor three 16 drives the rotating rod 18 to rotate, and the two charging guns 6 also rotate. At this time, if the tension detected by the three-pulley tension sensor 11 gradually decreases, it means that the two charging lines 4 are separating. On the contrary, if the tension detected by the three-pulley tension sensor 11 increases again, the motor three 16 immediately drives the rotating rod 18 to reverse, so that The two charging cables 4 are untied. When the three-pulley tension sensor 11 detects that the tension of the charging cable 4 is gradually approaching the normal value, the two clamping plates 38 can be driven to loosen the charging gun 6, and the mounting seat 12 can be reset to the inner cavity of the charging pile 1. At this time, the winding disk 26 can be driven to rotate again to reel the charging cable 4, so that the charging gun 6 is reset to the blocking block 36, thereby avoiding the situation where the two charging cables 4 are entangled due to external forces when the two charging guns 6 are reset at the same time. This not only ensures the subsequent normal use of the charging gun 6, but also avoids the situation where the two charging cables 4 are damaged due to stretching due to the two charging cables 4 being tightly wound and the winding disk 26 continues to rotate, thereby further improving safety.

[0047] Furthermore, although the two clamps 38 loosen the charging gun 6 when the three-pulley tension sensor 11 detects that the tension of the charging cable 4 is gradually approaching the normal value, the two clamps 38 release the charging gun 6. However, the charging cable 4 may still be slightly entangled at this time. If the charging cable 4 is reeled in, the two charging cables 4 may still be tightened against each other and cannot be separated. Therefore, in order to avoid this situation, during the separation of the two charging cables 4, the lower pressure rod 10 is above the two charging cables 4, and the lower pressure rod 10 is aligned with the angle between the two charging cables 4. When the clamp 38 no longer clamps the charging gun 6, the motor 7 33 drives the threaded rod 2 34 to rotate, so that the lower pressure rod 10 can be lowered. At this time, if the charging cable 4 is still slightly entangled, the lower pressure rod 10 will push the two charging cables 4 at the angle caused by their entanglement, so that the two charging cables 4 are completely separated, thereby preventing the situation that the charging cable 4 is still slightly entangled after the clamp 38 is away from the charging gun 6, and the two charging cables 4 are tightened against each other and cannot be separated again when the winding disk 26 reels the charging cable 4.

[0048] In this embodiment, Figure 1 As shown, a plurality of universal wheels 3 are provided on the lower end surface of the base 2 .

[0049] Specifically, the universal wheels 3 can be used to conveniently move the entire charging pile 1 , thereby facilitating operations such as transporting the charging pile 1 .

[0050] Working principle: The universal wheel 3 can be used to conveniently move the entire charging pile 1, so as to facilitate the transportation of the charging pile 1. When the new energy vehicle cannot be moved near the charging pile 1, the personnel can hold the charging gun 6 and use the motor 5 25 to drive the winding disk 26 to rotate, and the winding disk 26 unwinds the charging line 4. At the same time, the personnel can carry the charging gun 6 to the side of the car and use the charging gun 6 to charge the car, thereby eliminating the process of moving the charging pile 1 back and forth, which is more labor-saving. At the same time, the other charging gun 6 can also perform the charging work, thereby improving the charging efficiency. When the charging After the charging cable 4 is unwound, since the unwinding of the charging cable 4 may be long, if the personnel carry the charging gun 6 back to the charging pile 1, they need to walk a long way, which is troublesome. If the charging cable 4 is reeled in, the charging gun 6 will slide on the ground, which is easy to damage the charging gun 6. Therefore, in order to avoid this situation, after charging is completed, the motor 8 can be used to drive the fan wheel 35 on one side to rotate, and the two protective shells 9 can be driven by the two fan wheels 35 to rotate in different directions at the same time. When the two protective shells 9 are attached, the charging gun 6 is covered. At this time, the personnel can put down the charging gun 6. When the charging gun 6 falls, the protective shells 9 will be The shell 9 will protect the charging gun 6. During the whole rewinding process, the charging gun 6 will not directly contact the ground until the charging gun 6 is suspended again. The two protective shells 9 are separated, and the connecting handle 7 of the charging gun 6 is fitted with the bottom of the blocking block 36, thereby eliminating the process of personnel carrying the charging gun 6 to reset it to its original position, which is more convenient. At the same time, it also avoids the situation where the charging gun 6 is damaged due to contact and friction with the ground when the charging gun 6 is automatically reset, and has high safety. Since there are two charging guns 6, when the two charging guns 6 are reset at the same time, the two charging lines 4 may be entangled due to external forces and other factors. Not only does it affect the subsequent use, but also, when the two charging cables 4 are tightly wound, if the winding disk 26 continues to rotate, the two charging cables 4 will be damaged due to stretching. Therefore, in order to avoid this situation, when the charging cable 4 is wound and unwound, the tension of the charging cable 4 can be detected by the three-pulley tension sensor 11. The three-pulley tension sensor 11 is provided with a force-bearing wheel and two positioning wheels. The charging cable 4 passes through the gap between the force-bearing wheel and the positioning wheel, and fits with the surface of the positioning wheel and the force-bearing wheel. When the charging cable 4 moves, the tension of the charging cable 4 can be monitored in real time. The above monitoring process is a prior art and will not be described in detail.If the charging cable 4 is not entangled, the tension value of the charging cable 4 monitored by the three-pulley tension sensor 11 is within a reasonable range. When the charging cable 4 is entangled, if the two charging guns 6 are still resetting at this time, since the shell 5 is in contact with the ground, the ground provides support for the shell 5. Therefore, even if the charging cable 4 is entangled at this time, the tension is within a normal range. When the charging gun 6 moves to the front of the charging pile 1 and is suspended in the air, if the winding cannot separate the two charging cables 4, the connecting handle 7 at the end of the charging gun 6 will not contact the blocking block 36. At this time, the winding will only stretch the two charging cables 4, and the tension of the charging cable 4 monitored by the three-pulley tension sensor 11 gradually increases. Trend, at this time, the winding disk 26 stops rotating, and the charging line 4 is no longer wound, then the motor six 30 drives the threaded rod one 32 to rotate, so that the baffle 31 moves laterally and no longer covers the extension port 37. At this time, the electric push rod 28 can be used to drive the mounting seat 12 to extend from the inner cavity of the charging pile 1, and then the motor two 13 is used to drive the connecting rod one 14 and the connecting rod two 15 to rotate, so that the tray 19 rises. When the tray 19 contacts the suspended charging gun 6 and provides support for the charging gun 6, the charging line 4 will be slightly relaxed because the charging gun 6 is supported. At this time, the tension detected by the three-pulley tension sensor 11 will become smaller. When the tension becomes smaller, the tray 19 will stop rising, and then the motor four 23 is used to drive the two-way The threaded rod 24 rotates to bring the two slide plates 20 closer to each other. Since the two charging guns 6 are also fitted together when the charging line 4 is wound, the two clamping plates 38 can be used to clamp the two charging guns 6. At the same time, under the action of the slide column 21 and the spring 22, the charging gun 6 also has a buffering effect to prevent the charging gun 6 from being damaged. When the two charging guns 6 are clamped, the motor three 16 drives the rotating rod 18 to rotate, and the two charging guns 6 also rotate. At this time, if the tension detected by the three-pulley tension sensor 11 gradually decreases, it means that the two charging lines 4 are separating. On the contrary, if the tension detected by the three-pulley tension sensor 11 increases again, the motor three 16 immediately drives the rotating rod 18 to reverse, so that The two charging cables 4 are untied. When the three-pulley tension sensor 11 detects that the tension of the charging cable 4 is gradually approaching the normal value, the two clamping plates 38 can be driven to loosen the charging gun 6, and the mounting seat 12 can be reset to the inner cavity of the charging pile 1. At this time, the winding disk 26 can be driven to rotate again to reel the charging cable 4, so that the charging gun 6 is reset to the blocking block 36, thereby avoiding the situation where the two charging cables 4 are entangled due to external forces when the two charging guns 6 are reset at the same time. This not only ensures the subsequent normal use of the charging gun 6, but also avoids the situation where the two charging cables 4 are damaged due to stretching due to the two charging cables 4 being tightly wound and the winding disk 26 continues to rotate, thereby further improving safety.Furthermore, although the two clamping plates 38 loosen the charging gun 6 when the three-pulley tension sensor 11 detects that the tension of the charging line 4 is gradually approaching the normal value, the two clamping plates 38 still loosen the charging gun 6, but the charging line 4 may still be slightly entangled at this time. If the charging line 4 is reeled in, the two charging lines 4 may still be tightened and unable to separate. Therefore, in order to avoid this situation, during the separation of the two charging lines 4, the lower pressure rod 10 is above the two charging lines 4, and the lower pressure rod 10 is aligned with the angle between the two charging lines 4. When the clamping plate 38 no longer clamps the charging gun 6, the motor 7 33 drives the threaded rod 2 34 to rotate, so that the lower pressure rod 10 can be lowered. At this time, if the charging line 4 is still slightly entangled, the lower pressure rod 10 will completely separate the two charging lines 4 by pushing the angle between the two charging lines 4 due to the entanglement, thereby preventing the situation that the charging line 4 is still slightly entangled after the clamping plate 38 is away from the charging gun 6, and the two charging lines 4 are tightened and unable to separate again when the winding disk 26 reels the charging line 4. ;
