[0034] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0035] Reference below Figure 1-Figure 5 The power adapter 1 of a vehicle according to an embodiment of the present invention is described. The power adapter 1 is mainly electrically connected to the vehicle, and the user can plug the load into the power adapter 1 to realize the external discharge function of the vehicle. Moreover, the power adapter 1 can be an American standard power adapter 1, a European standard power adapter 1, a Japanese standard power adapter 1, or a power adapter 1 of other standards.

[0036] like Figure 1-Figure 4 As shown, the power adapter 1 for a vehicle according to an embodiment of the present invention includes: an adapter body and a power module 10, the adapter body includes: an output module 20 and a telescopic control module 30, and a connecting line 40 is arranged in the telescopic control module 30. The adapter body is the main part of the power adapter 1, wherein the output module 20 is used to connect with an external device to power the external device, and the user can plug the load into the output module 20, and the telescopic control module 30 can control the telescopic function of the connecting line 40, and the connecting line 40 mainly plays the role of an intermediate connection. The power module 10 is mainly used to connect the vehicle to draw power from the vehicle. The connecting line 40 is mainly composed of an L line, an N line, a PE line and a CC signal line, wherein the CC line is a low-voltage signal line and needs to be shielded separately.

[0037] like Figure 1 and Figure 2As shown, the output module 20 is provided with a plug interface 22, so that the user can directly plug the load into the plug interface 22, so as to be electrically connected to the output module 20. The telescopic control module 30 is arranged between the power taking module 10 and the output module 20, that is, the telescopic control module 30 plays the role of an intermediate connection, and the power taking module 10 can pass the power from the vehicle to the telescopic control module 30, and then pass it to the output module 20 through the telescopic control module 30, so that the power can be output from the output module 20.

[0038] It should be noted that a receiving cavity is provided in the telescopic control module 30, and the connecting wire 40 is provided in the telescopic control module 30, that is, the connecting wire 40 is provided in the receiving cavity, so that the connecting wire 40 can be stored. One end of the connecting wire 40 is electrically connected to the power taking module 10, and the other end of the connecting wire 40 is electrically connected to the output module 20, that is, electrically connected to the plug interface 22. When the plug interface 22 is plugged into the vehicle, the current is first transmitted to the power taking module 10, and then the current can be transmitted to the output module 20 through the connecting wire 40. The user plugs the load into the output module 20 to provide electrical energy to the load.

[0039] like Figure 3 and Figure 4 As shown, the telescopic control module 30 is used to adjust the length of the connecting line 40 extending out of the telescopic control module 30. That is to say, when the power adapter 1 needs to work, the telescopic control module 30 can be manipulated to control the end of the connecting line 40 connected to the power taking module 10 to extend, and the connecting line 40 can be pulled out of the accommodating cavity, so that one end of the connecting line 40 can be plugged into the vehicle along with the power taking module 10, and the length of the connecting line 40 extending out of the telescopic control module 30 is adjusted by the telescopic control module 30, so that the other end of the connecting line 40 connected to the plug interface 22 of the output module 20 can be set away from the power taking module 10, so as to facilitate the load to be plugged into the plug interface 22 of the output module 20. Of course, when the load is powered off, the power taking module 10 is unplugged from the vehicle, and the telescopic control module 30 is manipulated to control the end of the connecting line 40 connected to the power taking module 10 to shrink into the accommodating cavity, and then the power taking module 10 is fixed to the output module 20 to complete the use process of the power taking adapter 1.

[0040] Therefore, by providing a connecting wire 40 in the telescopic control module 30, and the extension and retraction of the connecting wire 40 can be controlled by the telescopic control module 30, when the power taking adapter 1 is in use, the power taking module 10 can be plugged into the vehicle, and the extension length of the connecting wire 40 can be adjusted by the telescopic control module 30, so that the output module 20 can be set away from the power taking module 10, so that the user operation is more convenient and the plugging of the load is convenient, avoiding the situation where the load's own wiring harness is short and the user is required to prepare the output module 20 by himself, thereby avoiding the load being suspended, and avoiding the risk of poor contact caused by pulling, and leakage.

[0041] Optionally, the output module 20 is detachably connected to the telescopic control module 30. That is, when the power adapter 1 is working, the output module 20 can be detached from the telescopic control module 30, and the power module 10 connected to the telescopic control module 30 can be connected to the vehicle to draw power from the vehicle, and the output module 20 can be set away from the power module 10 and the telescopic control module 30, so as to facilitate the load to be plugged into the plug interface 22 of the output module 20.

[0042] Alternatively, the power taking module 10 is detachably connected to the telescopic control module 30. That is, when the power taking adapter 1 is working, the power taking module 10 can be removed from the telescopic control module 30 and then connected to the vehicle to take power from the vehicle, while the output module 20 connected to the telescopic control module 30 can be set away from the power taking module 10, which also facilitates the load to be plugged into the plug interface 22 of the output module 20.

[0043] Alternatively, the telescopic control module 30 includes: a first shell and a second shell, the first shell is connected to the power supply module 10, the second shell is connected to the output module 20, and the first shell and the second shell are detachably connected. Alternatively, the telescopic control module 30 is divided into a first shell and a second shell, wherein the first shell is connected to the power supply module 10, and the second shell is connected to the output module 20, and then the first shell and the second shell can be disassembled. When the power supply adapter 1 is working, the first shell and the second shell can be disassembled, the power supply module 10 connected to the first shell is connected to the vehicle to draw power from the vehicle, and the output module 20 connected to the second shell can be set away from the power supply module 10 and the first shell. Similarly, this also facilitates the load to be plugged into the plug interface 22 of the output module 20.

[0044] Among them, Figure 3 and Figure 4As shown, the telescopic control module 30 includes: a shell 31, a rotating shaft 32, an elastic member 33 and a placement box 34. The rotating shaft 32 is rotatably arranged in the shell 31. The connecting line 40 is wound on the rotating shaft 32. When the rotating shaft 32 rotates along a first direction, the extended length of the connecting line 40 gradually increases. When the rotating shaft 32 rotates along a second direction, the extended length of the connecting line 40 gradually decreases. The placement box 34 is fixed in the shell 31. The elastic member 33 is arranged in the placement box 34, and one end of the elastic member 33 is connected to the rotating shaft 32, so that when the rotating shaft 32 rotates along the second direction, the elastic member 33 provides power for the rotating shaft 32 to rotate. The first direction is opposite to the second direction.

[0045] The housing 31 can be used for installation and fixing, and the shaft 32 can mainly be used for rotation. The shaft 32 is arranged in the housing 31, so that the shaft 32 can be relatively fixed. Of course, the shaft 32 can be rotated. The connecting wire 40 is wound on the shaft 32. It can be understood that since one end of the connecting wire 40 is electrically connected to the power taking module 10, when the power taking module 10 drives the connecting wire 40 to extend outward, the connecting wire 40 rotates in the first direction, that is, moves outward, and the extension length of the connecting wire 40 gradually increases. At the same time, the connecting wire 40 will drive the shaft 32 to rotate in the first direction. When the shaft 32 rotates in the second direction, the shaft 32 will drive the connecting wire 40 to rotate in the second direction, that is, move inward. It can be understood that the extension length of the connecting wire 40 gradually decreases.

[0046] The elastic member 33 has an elastic effect, for example, the elastic member 33 can be a spring. It should be noted that the spring in a plane, that is, a spring that is wound into a plane spiral shape, is fixed, so it is necessary to set a placement box 34. The placement box 34 is first fixed in the housing 31 to fix the position of the placement box 34, and then the spring can be set in the placement box 34 for fixing, so that the setting of the spring is more stable and reliable. One end of the elastic member 33 is connected to the shaft 32. When the shaft 32 rotates in the second direction, one end of the elastic member 33 is subjected to a bending moment after the torque acts on it, resulting in a bending elastic deformation, so that the elastic member 33 is twisted in its own plane to provide power for the shaft 32 to rotate. When the load is powered off, the power extraction module 10 is pulled out of the vehicle. At this time, the shaft 32 will rotate in the second direction under the elastic action of the elastic member 33, so that the connecting line 40 will gradually shrink into the accommodating cavity under the drive of the shaft 32. In this way, the extension and contraction functions of the connecting line 40 can be realized.

[0047] Furthermore, if Figure 2-Figure 4As shown, the telescopic control module 30 also includes: a first limiter 35, which is used to cooperate with the rotating shaft 32 to limit the rotation of the rotating shaft 32. The first limiter 35 can play a limiting role, and the first limiter 35 cooperates with the rotating shaft 32. That is, when the power module 10 drives the connecting wire 40 to extend outward, and the connecting wire 40 extends to the required length, the first limiter 35 can be limited to cooperate with the rotating shaft 32, so that the first limiter 35 can limit the rotating shaft 32 from rotating in the opposite direction under the elastic action of the spring, thereby affecting the normal use of the power adapter 1. When the power adapter 1 is used, the limiting cooperation between the first limiter 35 and the rotating shaft 32 can be released, and the rotating shaft 32 rotates in the opposite direction under the elastic action of the spring, and the connecting wire 40 is driven by the rotating shaft 32 to shrink into the accommodating cavity. The first limiting member 35 and the rotating shaft 32 may be limited by a convex manner or by a buckle manner. Of course, other suitable structures may also be used for limiting cooperation.

[0048] Among them, Figure 2 As shown, the housing 31 is provided with a matching hole 36, and the first limiting member 35 extends out of the matching hole 36. The matching hole 36 is provided on the housing 31, so that the first limiting member 35 can be limitedly matched with the rotating shaft 32 in the accommodating cavity, and the first limiting member 35 can also extend out through the matching hole 36, so that it is convenient for the user to operate the first limiting member 35 outside the housing 31, for example: when the first limiting member 35 is a convex, the first limiting member 35 can be pressed to limit the first limiting member 35 and the rotating shaft 32, and then the first limiting member 35 can be pressed for the second time to release the limiting match between the first limiting member 35 and the rotating shaft 32.

[0049] In addition, if Figure 3 and Figure 4 As shown, the telescopic control module 30 further includes: a second limiter 37, two second limiters 37, the two second limiters 37 are respectively arranged on the rotating shaft 32, and the connecting wire 40 is located between the two second limiters 37. The second limiter 37 can also play a limiting role, and two second limiters 37 are provided, and the two second limiters 37 are respectively arranged on the rotating shaft 32, so that the connecting wire 40 can be wound between the two second limiters 37. It can be understood that the two second limiters 37 can limit the two ends of the connecting wire 40 to prevent the connecting wire 40 from being piled up, thereby affecting the normal telescopic movement of the connecting wire 40.

[0050] In addition, if Figure 1As shown, the power adapter 1 of the vehicle further includes: a switch assembly 50, a maintenance window 38 is provided on the housing 31, the maintenance window 38 is arranged corresponding to the rotating shaft 32, and the switch assembly 50 is arranged at the maintenance window 38. The housing 31 is provided with a maintenance window 38, so that the inside of the housing can be repaired through the maintenance window 38, and the maintenance window 38 is arranged opposite to the rotating shaft 32, so that the connection wires 40 accumulated at the rotating shaft 32 can be processed through the maintenance window 38 to avoid the accumulation of the connection wires 40 and causing the connection wires 40 to be normally extended and retracted. The switch assembly 50 can play the role of a switch, and the switch assembly 50 is arranged at the maintenance window 38. When maintenance is required through the maintenance window 38, the switch assembly 50 can be controlled to open the maintenance window 38. When the maintenance is completed, the switch assembly 50 can be controlled to close the maintenance window 38 to prevent external debris from entering the housing 31 through the maintenance window 38 and affecting the normal operation of the telescopic control module 30.

[0051] Furthermore, if Figure 1 As shown, the switch assembly 50 includes: a switch member and a baffle 51, the baffle 51 is arranged at the maintenance window 38, and the switch member is control-connected with the baffle 51. The switch member can play a control role, and the baffle 51 is arranged at the maintenance window 38, so that the baffle 51 can cover the maintenance window 38, and the switch member is control-connected with the baffle 51, so that the switch member can control the baffle 51 to open the maintenance window 38, and can also control the baffle 51 to close the maintenance window 38. Among them, the switch member and the baffle 51 can be controlled by a mechanical structure connection, or by an electrical connection, or by an external Bluetooth connection, or by an app on an electronic device, and of course, it can also be controlled by other reasonable methods.

[0052] It should be noted that the outer surface of the connecting wire 40 is provided with a size mark, and the size mark is used to show the extension length of the connecting wire 40. That is to say, a scale is also provided on the outer skin of the connecting wire 40. Preferably, the end of the connecting wire 40 connected to the power taking module 10 is the initial mark of the size, that is, the scale, so that when the connecting wire 40 is extended, the maximum extension length of the connecting wire 40 can be clearly understood, so that the distance between the vehicle and the load can be planned according to the maximum extension size of the connecting wire 40, so that the load can be connected reasonably and effectively.

[0053] Among them, Figure 2As shown, the housing 31 is provided with a first clamping portion 39, and the power taking module 10 is provided with a second clamping portion 11, and the first clamping portion 39 is clamped and matched with the second clamping portion 11. The housing 31 is provided with a first clamping portion 39, and the power taking module 10 is provided with a second clamping portion 11, so that the first clamping portion 39 can be clamped and matched with the second clamping portion 11. It should be noted that the connection between the clamping structures is simple and firm, which is convenient for the installation between the housing 31 and the power taking module 10, and can improve the installation efficiency. It is also convenient for disassembly, which can make the disassembly between the housing 31 and the power taking module 10 simpler and more convenient. In addition, the structure of the clamping structure is simple and easy to manufacture and set up.

[0054] According to an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the output module 20 is provided with a plurality of plug-in surfaces 21, and at least one side of the plurality of plug-in surfaces 21 is provided with a plug-in interface 22. In other words, the output module 20 is a polyhedral structure, for example: the output module 20 can be a tetrahedral structure, one side of the output module 20 needs to be connected to the telescopic control module 30, so that the output module 20 is provided with three plug-in surfaces 21, and at least one of the three plug-in surfaces 21 is provided with a plug-in interface 22. Of course, preferably, the other sides of the output module 20 are provided with a plug-in interface 22, so that the output module 20 can perform multi-faceted discharge, which can avoid restrictions on the spatial position of the power adapter 1, thereby preventing the power adapter 1 from interfering with the vehicle during the discharge operation.

[0055] Furthermore, if Figure 2 As shown, there are multiple sockets 22, and at least one of the multiple sockets 22 is a USB interface 221. Multiple sockets 22 are provided, so that the power adapter 1 can supply power to multiple loads at the same time, which is convenient for multiple loads to be used at the same time. It can be understood that the multiple sockets 22 include a five-hole socket 220, which is mainly used for ordinary electrical appliances, and at least one of the multiple sockets 22 is a USB interface 221, which is convenient for the load wiring harness to be connected when it is a USB connector. For example: a mobile phone can be charged with a wiring harness without a charging head but with a USB interface 221, thereby improving the functionality of the power adapter 1 and facilitating user use. Among them, the voltage output by the USB interface 221 can be V, and the charging protocol of the USB interface 221 can be integrated with fast charging protocols such as DP and QC. in the later stage to realize the fast charging function.

[0056] It should be noted that if Figure 1 and Figure 2As shown, a trigger 23 is provided at each of the multiple plug interfaces 22, so that when a load is inserted into the plug interface 22, the corresponding trigger 23 is triggered, and the plug interface 22 is electrically connected to the load. That is to say, when a load is connected to the plug interface 22, the trigger 23 will be triggered due to the touch or press of the load plug, and the vehicle can detect the CC connection confirmation signal, that is, confirm that the plug interface 22 has a load connected. At this time, the plug interface 22 is powered, while other plug interfaces 22 are still not powered. On the contrary, when the load is unplugged, the trigger 23 is restored, and the plug interface 22 corresponding to the trigger 23 is automatically tripped and powered off. When all loads are unplugged, the entire output module 20 is not powered, and each branch is independently locked. Among them, the trigger 23 of the five-hole socket 220 can be set on the outside of the plug interface 22, and its trigger logic is that the load is triggered by pressing at the plug interface 22, while the trigger 23 of the USB interface 221 can be set inside the plug interface 22, and its trigger logic is that the load is triggered by the reed at the plug interface 22.

[0057] like Figure 5 As shown, it is a schematic diagram of the multi-channel independent locking discharge protection function. The system of the present invention is composed of the following parts: RC is a CC discharge detection resistor, P1, P2, ... Pn are five-hole sockets 220 of the output module 20, and n is a natural number series. The last power output is a 5V USB interface 221 output, and the USB interface 221 is represented by PU; k1, k2 ... kn, kU are electromagnetic relays with a control voltage of 12VDC / 250V / 10A; S1, S2, S3 ... Sn, SU are dual-channel linkage triggers 23; 5V / 12V output DC-DC power module; D1, D2, ... Dn, DU are power output indicator lights 24;

[0058] When a load is inserted into any plug interface 22, the Sn double trigger element 2318 is pressed, and the Sn-1 and Sn-2 circuits are connected simultaneously.

[0059] Loop 1: S1-1, S2-2, S3-1...Sn-1, SU-1 are parallel systems. When one of them is triggered, the RC discharge detection resistor is connected to the V2L system, and V2L starts to discharge. The L~N bus outputs 220VAC. The DC-DC power module works to output DC5V / DC12V DC power supply;

[0060] Circuit 2: Sn-2 trigger 23 is actuated, the corresponding Kn relay coil is energized with DC12V and is closed, the Kn relay node is turned on, and the corresponding Pn plug interface 22 outputs 220VAC AC power;

[0061] USB output: Similarly, when the USB plug is inserted into the USB interface 221, the two trigger elements 23 of SU-1 and SU-2 are triggered to turn on at the same time. SU-1 is turned on, the RC discharge detection resistor is connected to the V2L system, and V2L starts to discharge. The DC-DC power supply module works to output a DC5V / DC12V DC power supply, of which 5V is used for USB interface 221 discharge; SU-2 is turned on, the KU relay coil is energized, the KU node is energized, and the current is output through the relay KU node.

[0062] Patent effect: It can realize multi-channel mechanical switch locking control.
