Description

Technical Field

[0001] This invention relates to the field of new energy two-in-one charger structure technology, specifically a two-in-one charger with a protective structure. Background Technology

[0002] When a new energy vehicle's battery is low, it needs to be charged. This is usually done using either household power or high-voltage power at a charging station. Therefore, a two-in-one charger is required, which can adaptively adjust to the required voltage environment and perform the conversion.

[0003] In hot weather, when new energy vehicles are charging at high voltage at charging stations, their power adapters operate under high voltage and hot conditions. At this time, the internal components are prone to overheating, which increases the wear and tear on the internal components and affects the lifespan of the two-in-one charger.

[0004] Therefore, we propose a two-in-one charger with a protective structure. Summary of the Invention

[0005] The purpose of this invention is to provide a two-in-one charger with a protective structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a two-in-one charger with a protective structure, comprising an adapter housing, a plug wire, and a connector wire, wherein the plug wire and the connector wire are respectively disposed at two ends of the adapter housing;

[0007] It also includes: a control box, the adapter housing is fixedly connected to one end of the plug cable, a sliding hole is opened on the side wall of the control box, a sliding tube is slidably connected in the sliding hole, the sliding tube is fixedly sleeved on the plug cable, a plug connector is connected to one end of the plug cable inside the control box, and an access head is fixedly connected to one end of the adapter housing inside the control box, and the plug connector is slidably inserted into the access head.

[0008] Inside the control box, between one side of the adapter housing and the slide tube, there is a control component used to control the connection between the plug and the connector.

[0009] A limiting element is also provided between the connector and the plug to limit the connection between them.

[0010] The adapter housing is equipped with a heat-conducting component to conduct heat within the adapter housing;

[0011] The adapter housing also has an independent heat sink for cooling the area inside the adapter housing.

[0012] Furthermore, the control component includes a thermal spring, which is fixedly connected to one side of the adapter housing located in the control box. A limit ring is fixedly connected to the outer periphery of the slide tube. The end of the thermal spring is fixedly connected to the side of the limit ring. A heat-conducting coil is fixedly connected to one side of the adapter housing located in the control box. The end of the thermal spring near the adapter housing is fixedly inserted into the side wall of the heat-conducting coil.

[0013] Furthermore, the limiting component includes an extension frame, which is fixedly connected to the side of the access head near the plug. Two opposite sidewalls of the extension frame are provided with through grooves. A limiting block is provided in the through grooves through a connecting member. An inner groove is provided on the side of the limiting block near the plug. A limiting plate is slidably connected in the inner groove. A sliding groove is provided on the side of the plug. A limiting rod is provided in the sliding groove through a torsion member. The side of the limiting rod is attached to the side of the limiting plate. An inclined support rod is also fixedly connected in the sliding groove. The end of the inclined support rod is attached to the side of the limiting rod. The edge of the limiting plate away from the adapter housing is inclined.

[0014] Furthermore, the connector includes a connecting rod, which is hinged to the side of the limiting block away from the plug, and the end of the connecting rod is hinged to the side of the limiting ring, wherein there is a gap between the two opposite sides of the limiting block and the two inner sidewalls opposite to the through groove.

[0015] Furthermore, the torsion member includes two circular grooves, which are respectively opened on the upper and lower side walls of the slide groove. A torsion spring is fixedly connected in each of the two circular grooves, and the two torsion springs are respectively fixedly connected to the upper and lower ends of the limiting rod.

[0016] Furthermore, a number of guide brackets are fixedly connected to the side of the control box away from the adapter housing, and guide wheels are rotatably connected to the ends of the guide brackets, with the outer periphery of the guide wheels fitting against the outer periphery of the plug cable.

[0017] Furthermore, the heat-conducting component includes two heat-conducting holes and a vent hole. The two heat-conducting holes are located on the side of the adapter housing facing the control box, and the vent hole is located on the side of the adapter housing away from the control box. A mounting bracket is fixedly connected inside the heat-conducting holes, and a heat-conducting fan is rotatably connected to the side of the mounting bracket. Two heat exhaust holes are located on the side of the control box away from the adapter housing.

[0018] Furthermore, the independent heat sink includes heat dissipation holes opened on two opposite side walls of the adapter housing, a heat sink frame fixedly connected inside the heat dissipation holes, and a heat dissipation fan rotatably connected to the heat sink frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. When in use, the thermal spring and limiting component can be used to quickly disconnect the plug from the input head when the internal temperature of the adapter exceeds a certain threshold. Then, the independent heat sink is used to cool down the internal temperature of the adapter. After the temperature returns to normal, the thermal spring and limiting component can be used to reinsert the plug into the input head to allow the charger to work normally. This reduces the loss of the charger when it is working at high temperature in hot environments and improves the service life of the charger.

[0021] 2. The limiting block is rotatably connected in the through groove. The end of the connecting rod is hinged to the limiting block. When the thermal spring extends, it will pull the limiting ring to move. The limiting ring will pull the connecting rod to move, and the connecting rod will pull the limiting block to rotate so that the limiting rod can be released from the limiting plate. When the limiting rod is re-inserted into the access head along with the plug, the limiting plate limits it to prevent the limiting rod from being pushed by the inclined surface of the limiting plate and following the rotation of the torsion member, thereby affecting the re-insertion of the plug into the access head.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-8 The present invention provides a two-in-one charger with a protective structure, including an adapter housing 1, a plug wire 2 and a connector wire 3, wherein the plug wire 2 and the connector wire 3 are respectively disposed at two ends of the adapter housing 1;

[0033] It also includes: a control box 4, an adapter housing 1 fixedly connected to one end of the plug wire 2, a sliding hole 5 opened on the side wall of the control box 4, a sliding tube 6 slidably connected in the sliding hole 5, the sliding tube 6 fixedly sleeved on the plug wire 2, a plug connector 7 connected to one end of the plug wire 2 inside the control box 4, and an access head 8 fixedly connected to one end of the adapter housing 1 inside the control box 4, the plug connector 7 slidably inserted into the access head 8;

[0034] Inside the control box 4, between one side of the adapter housing 1 and the slide tube 6, there is a control component 9, which is used to control the connection between the plug 7 and the access head 8.

[0035] A limiting element 10 is also provided between the access head 8 and the plug 7 to limit the connection between the access head 8 and the plug 7;

[0036] A heat-conducting element 11 is provided inside the adapter housing 1 to conduct heat inside the adapter housing 1;

[0037] An independent heat sink 12 is also provided inside the adapter housing 1 for cooling the area inside the adapter housing 1.

[0038] In this embodiment, reference Figure 1Plug the plug on plug line 2 into the appropriate high-voltage socket in the charging station, and plug the connector on connector line 3 into the corresponding high-voltage charging port on the new energy vehicle. Under the influence of the external hot environment, the temperature of the internal components of the charger's adapter housing 1 will gradually rise.

[0039] refer to Figure 3 When the temperature inside the adapter housing 1 rises, it will conduct the internal temperature to the control box 4. When the temperature inside the control box 4 rises, refer to... Figure 4 The control element 9 will move the slide tube 6 due to the increased temperature, causing the slide tube 6 to pull the end of the plug wire 2, thereby pulling the connector 7 away from the connector 8, and thus stopping the components inside the adapter housing 1 of the charger from working. (Refer to...) Figure 3 The independent heat sink 12 is used to cool the inside of the adapter housing 1. When the temperature drops to a suitable level, refer to... Figure 4 At this point, the control unit 9 will be used to reinsert the connector 7 into the connector 8, allowing the charger to work normally and reducing the high losses caused by the high temperature environment and high voltage operation during use, which would affect the lifespan of the charger.

[0040] In a further preferred embodiment of the invention, such as Figure 4 As shown, the control component 9 includes a thermal spring 13, which is fixedly connected to the adapter housing 1 on one side of the control box 4. A limit ring 14 is fixedly connected to the outer periphery of the slide tube 6. The end of the thermal spring 13 is fixedly connected to the side of the limit ring 14. A heat-conducting coil 15 is fixedly connected to the adapter housing 1 on one side of the control box 4. The end of the thermal spring 13 near the adapter housing 1 is fixedly inserted into the side wall of the heat-conducting coil 15.

[0041] In this embodiment, reference Figure 4 When the temperature inside the adapter increases, the heat is conducted by the heat-conducting coil 15 (the heat-conducting coil 15 is made of graphene or thermally conductive silicone and has good thermal conductivity), so that the thermal spring 13 can absorb the heat inside the adapter housing 1. As the temperature increases, the thermal spring 13 will gradually extend, thereby pushing the limiting ring 14 to move away from the connector 8. There is a gap between the limiting ring 14 and the side of the control box 4 away from the adapter housing 1 to facilitate the movement of the limiting ring 14. At the same time, the thermal spring 13 extends and drives the limiting ring 14 to move a farther distance. When the temperature conducted by the heat-conducting coil 15 reaches a certain threshold, the thermal spring 13 drives the limiting ring 14 to pull the slip ring to move, thereby pulling the plug wire 2 and the connector 7 to move, so that they are freed from the limitation of the limiting member 10, and the connector 7 is freed from the connector 8.

[0042] Subsequently, the heat sink is used to dissipate heat inside the adapter housing 1. When the temperature inside the adapter housing 1 is low, the thermal spring 13 will retract. After the temperature cools down to the normal value, the thermal spring 13 pulls the limit ring 14, and finally drives the plug 7 to be reinserted into the connector 8, so that the plug wire 2 and the components inside the adapter housing 1 are powered again, reducing the loss caused by the adapter being too hot.

[0043] In a further preferred embodiment of the invention, such as Figures 6-8 As shown, the limiting member 10 includes an extension frame 16, which is fixedly connected to the side of the access head 8 near the plug 7. The two opposite side walls of the extension frame 16 are provided with through grooves 17. A limiting block 18 is provided in the through groove 17 through a connector. An inner groove 19 is provided on the side of the limiting block 18 near the plug 7. A limiting plate 20 is slidably connected in the inner groove 19. A sliding groove 21 is provided on the side of the plug 7. A limiting rod 22 is provided in the sliding groove 21 through a torsion member. The side of the limiting rod 22 is in contact with the side of the limiting plate 20. An inclined support rod is also fixedly connected in the sliding groove 21. The end of the inclined support rod is in contact with the side of the limiting rod 22. The edge of the limiting plate 20 away from the adapter housing 1 is inclined.

[0044] In this embodiment, reference Figures 6-8 In the initial state, a limiting block 18 is rotatably connected within the through slot 17. An inner groove 19 is formed on the side of the limiting block 18, and a limiting plate 20 is slidably connected within the inner groove 19. The outer wall of the limiting plate 20 is in contact with the inner wall of the inner groove 19, and the edge of the limiting plate 20 away from the adapter is inclined. The edge of the limiting plate 20 abuts against the side of the limiting rod 22. When the connector 7 is inserted into the access head 8, the limiting plate 20 abuts against the limiting rod 22, thereby limiting the connector 7 and preventing the thermal spring 13 from overheating before reaching a safe temperature. When the extension of the spring 13 pulls the connector 7 out of the connector 8, and the thermal spring 13 introduces a high temperature that exceeds the safe temperature, the extension force of the thermal spring 13 causes the limiting rod 22 to press against the limiting plate 20. This force allows the limiting rod 22 to rotate through the torsion member, causing the limiting rod 22 to tilt after being twisted. The limiting block 18 will then rotate in the opposite direction to the limiting rod 22 in coordination with the pulling force of the connector. At this time, the limiting rod 22 is released from the limitation of the limiting plate 20. Subsequently, the thermal spring 13 finally causes the connector 7 to disengage from the connector 8, causing the charger to stop working.

[0045] After the thermal spring 13 cools down and returns to normal temperature, it will cause the connector 7 to move into the connector 8. The limiting rod 22 will push the limiting plate 20 to one side, pushing the limiting plate 20 into the inner groove 19. Then the limiting rod 22 will pass over the limiting plate 20, and the connector 7 will be reinserted into the connector 8. The limiting plate 20 will return to its original position due to the air pressure inside the inner groove 19, limiting the limiting rod 22. At this time, the charger will start working again.

[0046] In a further preferred embodiment of the invention, such as Figure 5 As shown, the connector includes a connecting rod 23, which is hinged to the side of the limiting block 18 away from the plug 7. The end of the connecting rod 23 is hinged to the side of the limiting ring 14. A gap is left between the two opposite sides of the limiting block 18 and the two inner sidewalls opposite to the through groove 17.

[0047] In this embodiment, reference Figure 5 The limiting block 18 is rotatably connected in the through groove 17. The end of the connecting rod 23 is hinged to the limiting block 18. When the thermal spring 13 extends, it will pull the limiting ring 14 to move. The limiting ring 14 pulls the connecting rod 23 to move. The connecting rod 23 will then pull the limiting block 18 to rotate so that the limiting rod 22 can be released from the limiting plate 20. When the limiting rod 22 is reinserted into the access head 8 along with the plug 7, the limiting plate 36 prevents the limiting rod 22 from being pushed by the inclined surface of the limiting plate 20 and following the rotation of the torsion member, thereby affecting the reinsertion of the plug 7 into the access head 8.

[0048] In a further preferred embodiment of the invention, such as Figure 7 As shown, the torsion member includes two circular grooves 24, which are respectively opened on the upper and lower side walls of the slide groove 21. A torsion spring 25 is fixedly connected in each of the two circular grooves 24, and the two torsion springs 25 are respectively fixedly connected to the upper and lower ends of the limiting rod 22.

[0049] In this embodiment, reference Figure 7 Within the slide groove 21, circular grooves 24 are formed on the upper and lower sides of the limiting rod 22. A torsion spring 25 is fixedly connected within the circular groove 24. The end of the torsion spring 25 is connected to the corresponding end of the limiting rod 22. Therefore, under the drive of the thermal spring 13, the limiting rod 22 will be pushed to rotate when the limiting plate 20 rotates with the limiting block 18, causing the limiting rod 22 to disengage from the limiting plate 20, allowing the connector 7 to disengage from the access head 8. Subsequently, the torsion spring 25 drives the limiting rod 22 to rotate back to its original position.

[0050] In a further preferred embodiment of the invention, such as Figure 1As shown, a number of guide brackets 26 are fixedly connected to the side of the control box 4 away from the adapter housing 1. The end of the guide bracket 26 is rotatably connected to a guide wheel 27, and the outer periphery of the guide wheel 27 is in contact with the outer periphery of the plug cable 2.

[0051] In this embodiment, reference Figure 1 The plug wire 2 is constrained by several guide wheels 27, which reduces the friction on the plug wire 2 during movement and prevents the plug wire 2 from being pulled too far in other directions, thereby affecting the movement of the slide tube 6 and thus affecting the operation of the plug 7 in and out of the connector 8.

[0052] In a further preferred embodiment of the invention, such as Figures 2-3 As shown, the heat-conducting component 11 includes two heat-conducting holes 28 and a vent hole 29. The two heat-conducting holes 28 are opened on the side of the adapter housing 1 located in the control box 4, and the vent hole 29 is opened on the side of the adapter housing 1 away from the control box 4. A mounting bracket 30 is fixedly connected inside the heat-conducting holes 28, and a heat-conducting fan 31 is rotatably connected to the side of the mounting bracket 30. Two heat exhaust holes 32 are opened on the side of the control box 4 away from the adapter housing 1.

[0053] In this embodiment, reference Figures 2-3 A suitable motor is fixedly installed on the mounting bracket 30 away from the heat conduction fan 31. The motor at this position is connected in parallel with the wiring in the charger. When the charger is started, the motor at this position will start, thereby driving the heat conduction fan 31 to rotate. This will draw the air inside the adapter housing 1 into the control box 4, thereby delivering the high-temperature air inside the adapter housing 1 to the control box 4, and then expelling it from the heat exhaust hole 32. The high-temperature air delivered to the control box 4 is absorbed by the thermal spring 13, so as to accurately control the working state of the charger.

[0054] In a further preferred embodiment of the invention, such as Figures 1-3 As shown, the independent heat sink 12 includes heat dissipation holes 33 opened on two opposite side walls of the adapter housing 1, a heat sink 34 fixedly connected inside the heat dissipation holes 33, and a heat sink fan 35 rotatably connected to the heat sink 34.

[0055] In this embodiment, reference Figure 1-3 A heat dissipation hole 33 is provided on the side of the adapter housing 1. A suitable motor is installed on the side of the heat dissipation bracket 34 away from the heat dissipation fan 35. An independent power supply and a programmable controller are installed inside the adapter housing 1. The controller is connected to the circuit board of the charger. If the plug wire 2 is in the on state and the circuit inside the adapter housing 1 is in the off state, the motor at the heat dissipation fan 35 will start to dissipate heat for the internal components of the adapter. If the plug wire 2 is not connected to the power supply, the power supply at that position will be in the off state.

[0056] Working principle: When the connector 7 is inserted into the connector 8, the limiting plate 20 abuts against the limiting rod 22, thereby limiting the connector 7. This prevents the thermal spring 13 from extending and pulling the connector 7 out of the connector 8 if the temperature rises but does not exceed the safe temperature. When the thermal spring 13 reaches a high temperature exceeding the safe temperature, the extension force of the thermal spring 13 causes the limiting rod 22 to press against the limiting plate 20. This force allows the limiting rod 22 to rotate through the torsion member, causing it to tilt. The limiting block 18 then rotates in the opposite direction to the limiting rod 22 in conjunction with the pulling force of the connector. At this point, the limiting rod 22 is released from the limitation of the limiting plate 20. Finally, the thermal spring 13 causes the connector 7 to disengage from the connector 8, stopping the charger from working.

[0057] After the thermal spring 13 cools down and returns to normal temperature, it will cause the connector 7 to move into the connector 8. The limiting rod 22 will push the limiting plate 20 to one side, pushing the limiting plate 20 into the inner groove 19. Then the limiting rod 22 will pass over the limiting plate 20, and the connector 7 will be reinserted into the connector 8. The limiting plate 20 will return to its original position due to the air pressure inside the inner groove 19, limiting the limiting rod 22. At this time, the charger will start working again.
