[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0036] like Figures 1 to 11 As shown in the embodiment of the present invention, a high-voltage interlock connector includes a mounting base 1, a connecting base 11 fixed at one end of the mounting base 1, a limit block 111 fixed at the top of the connecting base 11, a mating base 2 adapted to the connecting base 11 on the outside of the connecting base 11, the mating base 2 being able to be sleeved on the connecting base 11, guide grooves being provided on the side and bottom of the mating base 2, and slide bars being provided at corresponding positions of the guide grooves of the connecting base 11 and the mating base 2, the guide grooves and slide bars being slidably connected, a pressing plate 21 being rotatably connected to the top of the mating base 2, a limit pressure ring 211 being fixed at one end of the pressing plate 21 near the connecting base 11, a first spring 234 being provided below the pressing plate 21, the bottom end of the first spring 234 being fixedly connected to the mating base 2, a plug 22 being engaged below the pressing plate 21, an expansion ring 3 being provided at one end of the connecting base 11 near the mounting base 1 on the outside of the connecting base 11, and an expansion plate 41 being provided at one side of the top of the mating base 2 near the connecting base 11;
[0037] There are many circuits inside new energy vehicles. High-voltage circuits are connected using high-voltage interlock connectors. In use, mounting base 1 is installed inside the vehicle, and the circuit to be connected is connected to the components inside mounting base 1. Then, the input cable is installed at the tail of docking base 2 and connected to the components inside docking base 2. Next, docking base 2 is inserted into the outside of connecting base 11. At this time, the guide grooves on the side and bottom of docking base 2 are aligned with the corresponding sliding strips of connecting base 11. Then, docking base 2 is pushed towards mounting base 1. At this time, docking base 2 is inserted into the outside of connecting base 11. At this time, the components inside docking base 2 and connecting base 11 can be connected. During the connection process, the internal detection module detects that docking base 2 and connecting base 11 are connected and can connect the high voltage.
[0038] During the process of fitting the docking seat 2 onto the connecting seat 11, the limiting pressure ring 211 will contact the limiting block 111. After contacting the limiting block 111, the limiting pressure ring 211 will be pushed up by the inclined surface of the limiting block 111 as the docking seat 2 is pushed. At this time, the lifting of the limiting pressure ring 211 will drive the pressing plate 21 to rotate. When the pressing plate 21 rotates, it will squeeze the first spring 234 downward. When the docking seat 2 and the connecting seat 11 are fully fitted together, the end of the limiting pressure ring 211 away from the pressing plate 21 slides to the side of the limiting block 111 closer to the mounting seat 1. At this time, the limiting pressure ring 211 loses its pushing force, and the elastic force of the first spring 234 pushes the pressing plate 21 to rotate. The pressing plate 21 drives the limiting pressure ring 211 to rotate. At this time, the limiting pressure ring 211 rotates so that it fits onto the outside of the limiting block 111. Under the limiting action of the limiting pressure ring 211 on the limiting block 111, the docking seat 211 can be fitted onto the connecting seat 111. The mating seat 2 and the connecting seat 11 are locked together. When the pressing plate 21 drives the limiting ring 211 to rotate downward, the inner side of the end away from the pressing plate 21 gradually presses against the limiting block 111 and the side close to the mounting seat 1. At this time, the limiting ring 211 can press the limiting block 111 tightly, so that the mating seat 2 and the connecting seat 11 can be locked together. Then, the insert 22 is pushed into the pressing plate 21 to fix the pressing plate 21. During use, it can prevent the pressing plate 21 from being pushed and causing the mating seat 2 and the connecting seat 11 to separate. When it is necessary to separate the mating seat 2 and the connecting seat 11, first take the insert 22 out from under the pressing plate 21, and then press the pressing plate 21 downward. At this time, the pressing plate 21 drives the limiting ring 211 to lift up, which can separate the limiting ring 211 from the limiting block 111. Then the mating seat 2 can be pulled to separate it from the connecting seat 11.
[0039] During use, there will be a gap between the connecting seat 11 and the docking seat 2. In order to prevent water from entering the gap during use, an expansion ring 3 is set. The expansion ring 3 can fill the gap between the docking seat 2 and the connecting seat 11. It can prevent the external of the docking seat 2 from being accidentally soaked in water, which could cause water to enter the internal components and cause short circuits or corrosion. The expansion plate 41 can fill the top gap between the docking seat 2 and the connecting seat 11. It can work with the expansion ring 3 to waterproof at the same time, which can prevent water from entering the gap between the docking seat 2 and the connecting seat 11 when the car is driving through water.
[0040] like Figures 1 to 9 As shown, the limiting block 111 has a lifting groove on the side near the mounting base 1. An airbag 32 is provided at the bottom of the lifting groove. Air guide pipes 321 are fixed on both sides of the airbag 32. The other end of the air guide pipes 321 is connected to the expansion ring 3. A pressure block 31 is slidably connected to the upper part of the lifting groove. The limiting pressure ring 211 can press the pressure block 31 into the lifting groove.
[0041] After the docking seat 2 and the connecting seat 11 are docked, the limiting pressure ring 211 will move downward. At this time, the end of the limiting pressure ring 211 will squeeze the pressure block 31 into the interior of the lifting groove. The pressure block 31 will then squeeze the airbag 32 into the interior of the lifting groove. After the airbag 32 is squeezed, the gas inside will be filled into the interior of the expansion ring 3 through the air guide pipes 321 on both sides. At this time, the expansion ring 3 will expand and increase in volume, and the expansion ring 3 will fill the gap between the docking seat 2 and the connecting seat 11, thereby enhancing the sealing between the docking seat 2 and the connecting seat 11.
[0042] like Figures 1 to 9 As shown, a second spring 322 is fixed on both sides inside the airbag 32;
[0043] When it is necessary to separate the docking seat 2 and the connecting seat 11, the expansion ring 3 in its expanded state will affect the resistance when the docking seat 2 and the connecting seat 11 are separated. Therefore, a second spring 322 is set inside the airbag 32. When the pressure block 31 squeezes the airbag 32, the second spring 322 is squeezed. When it is necessary to separate the docking seat 2 and the connecting seat 11, the limiting pressure ring 211 will lift first. At this time, the elastic force of the second spring 322 will push the airbag 32 to restore its shape. At the same time, the airbag 32 will draw air into the interior of the expansion ring 3 through the air guide tube 321. At this time, the expansion ring 3 will restore its shape. At this time, the expansion ring 3 will not affect the separation of the docking seat 2 and the connecting seat 11. The elastic force of the first spring 234 is greater than the elastic force of the second spring 322.
[0044] like Figures 1 to 13As shown, a guide shell 43 is provided in the middle of the limiting pressure ring 211. The top of the guide shell 43 is fixedly connected to the docking seat 2. A lifting block 432 is slidably connected inside the guide shell 43. An air conveying belt 411 is fixed on the side of the guide shell 43 near the expansion plate 41. The other end of the air conveying belt 411 is fixedly connected to the expansion plate 41. The expansion plate 41 is connected to the inside of the guide shell 43 through the air conveying belt 411.
[0045] When the docking seat 2 is fitted onto the outside of the connecting seat 11, the docking seat 2 drives the lifting block 432 to move. After the limiting pressure ring 211 contacts the limiting block 111, the bottom end of the lifting block 432 will also contact the surface of the limiting block 111. When the limiting pressure ring 211 is fitted onto the outside of the limiting block 111, the limiting block 111 pushes the lifting block 432 into the inside of the guide shell 43. The lifting block 432 squeezes the air inside the guide shell 43. The air is introduced into the inside of the expansion plate 41 through the air conveyor belt 411. At this time, the expansion plate 41 will expand after being filled with air. After the expansion plate 41 expands, its volume increases and it can fill the gap between the top of the docking seat 2 and the connecting seat 11.
[0046] like Figures 1 to 13 As shown, a third spring 431 is provided inside the guide shell 43. The bottom end of the third spring 431 is fixedly connected to the lifting block 432, and the top end of the third spring 431 is fixedly connected to the docking seat 2.
[0047] When the lifting block 432 is pressed into the guide shell 43, the third spring 431 will be compressed. When the docking seat 2 and the connecting seat 11 are separated, the third spring 431 will push the lifting block 432 out of the guide shell 43. At this time, the guide shell 43 generates negative pressure and absorbs air into the expansion plate 41 through the air conveyor belt 411, which can restore the shape of the expansion plate 41. At this time, the expansion plate 41 can be separated from the connecting seat 11.
[0048] like Figures 1 to 11 As shown, a flap 4 is fixed on the side of the expansion plate 41 near the connecting seat 11, and a rotating shaft 42 is fixed on the top of the flap 4. The rotating shaft 42 is rotatably connected to the inside of the docking seat 2 near the connecting seat 11.
[0049] When the docking seat 2 and the connecting seat 11 are inserted and separated, the expansion plate 41 will block the structure at the top of the connecting seat 11. Therefore, a flap 4 is provided inside the docking seat 2 that can rotate. When the docking seat 2 and the connecting seat 11 are inserted and separated, the flap 4 can drive the expansion plate 41 to rotate to a position where it does not block the structure. At this time, the expansion plate 41 can be prevented from blocking the structure at the top of the connecting seat 11.
[0050] like Figures 7 to 12As shown, coil springs 421 are fixed to the outer sides of both ends of the rotating shaft 42. The other end of the coil springs 421 is fixedly connected to the docking seat 2. Gears 422 are fixed to both ends of the rotating shaft 42. The top of the gears 422 is meshed with a toothed plate 423. The toothed plate 423 is slidably connected inside the docking seat 2, and the end of the toothed plate 423 near the connecting seat 11 extends from the inside of the docking seat 2 to the outside.
[0051] In the initial state, the coil spring 421 drives the rotating shaft 42 to keep the flap 4 in a horizontal position against the top of the inside of the docking seat 2, and it is kept fixed by the elastic support of the coil spring 421. When the docking seat 2 and the connecting seat 11 are about to be fully inserted, the end of the toothed plate 423 will contact the surface of the mounting seat 1. When the docking seat 2 and the connecting seat 11 are fully inserted, the toothed plate 423 will be pushed into the inside of the docking seat 2. At this time, the toothed plate 423 will drive the gear 422 to rotate 90°. When the gear 422 rotates, it will drive the rotating shaft 42 to rotate 90°. At this time, the rotating shaft 42 drives the flip plate 4 to rotate 90°, and the flip plate 4 drives the expansion plate 41 to rotate into the working position. When the docking seat 2 and the connecting seat 11 are separated, the toothed plate 423 loses its support. At this time, the coil spring 421 will drive the rotating shaft 42 to rotate 90° in the opposite direction to reset. At this time, the rotating shaft 42 drives the expansion plate 41 to reset through the flip plate 4, which can make the expansion plate 41 automatically reset to prevent its position from affecting the insertion and separation of the docking seat 2 and the connecting seat 11. At the same time, the rotating shaft 42 can drive the toothed plate 423 to reset through the gear 422.
[0052] like Figures 1 to 10 As shown, the docking seat 2 has a storage cavity 24 inside, and a telescopic hole 241 is opened at the top of the storage cavity 24. A lifting column 23 is inserted inside the first spring 234. A top block 231 is fixed at the top of the lifting column 23. The bottom end of the lifting column 23 is inserted inside the telescopic hole 241. A conveying channel 243 is opened at the bottom of the storage cavity 24. An overflow groove 245 is opened inside the docking seat 2. Multiple distributing channels 244 are opened at the end of the conveying channel 243 away from the storage cavity 24. The ends of the multiple distributing channels 244 away from the conveying channel 243 are all connected to the inside of the overflow groove 245.
[0053] When docking seat 2 and connecting seat 11 are docked, pressing plate 21 rotates. During rotation, pressing plate 21 presses down on top block 231. Top block 231 drives lifting column 23 to extend into telescopic hole 241. At this time, the gas inside telescopic hole 241 enters storage chamber 24, which contains high-viscosity lubricating oil. The lubricating oil then enters distribution channel 244 through conveying channel 243. Distribution channel 244 delivers lubricating oil to multiple areas inside overflow tank 245, and finally, the lubricating oil enters overflow tank 245. Internally, after the docking seat 2 and the connecting seat 11 are inserted, the end of the connecting seat 11 away from the mounting seat 1 will contact the overflow groove 245. At this time, the lubricating oil will contact the end of the connecting seat 11. Under the push of the connecting seat 11, the lubricating oil will overflow a certain distance. At this time, the lubricating oil will fill the gap between the end of the connecting seat 11 and the interior of the docking seat 2. This can further enhance the sealing between the docking seat 2 and the connecting seat 11. At the same time, it plays a lubricating role when the docking seat 2 and the connecting seat 11 are separated, reducing the resistance during separation and preventing damage caused by excessive force during separation.
[0054] like Figures 1 to 10 As shown, the lifting column 23 has an air inlet 232 inside, and a one-way valve plate 233 is provided at the bottom of the lifting column 23.
[0055] When the lifting column 23 extends into the telescopic hole 241, the one-way valve plate 233 will block the bottom of the lifting column 23. At this time, the gas inside the telescopic hole 241 can be pushed. When the pressing plate 21 is reset, the first spring 234 will push the top block 231. At this time, the top block 231 will drive the lifting column 23 to reset. The lifting column 23 will rise from the inside of the telescopic hole 241. During the rising process, a negative pressure is generated inside the telescopic hole 241, which can cause the one-way valve plate 233 to be driven to flip downward. At the same time, the air inlet 232 will allow air to enter the inside of the telescopic hole 241, which can refill the inside of the telescopic hole 241 with air for convenient subsequent use.
[0056] like Figure 8 As shown, a feed hole 242 is provided on the side of the storage chamber 24 away from the connecting seat 11, and a sealing plug is provided inside the feed hole 242;
[0057] After multiple insertions and separations, in order to prevent the lubricating oil from running out, it needs to be added. At this time, the sealing plug of the feed hole 242 is removed, and then lubricating oil is injected into the storage chamber 24 through the feed hole 242. At this time, the storage chamber 24 can be replenished with lubricating oil. Then, the sealing plug is inserted into the feed hole 242.
