[0003] However, due to different uses, charging and discharging transmission tool cables are not universal. For example, when charging a vehicle, one end of the transmission tool cable is connected to the vehicle with an on-board electric gun, and the other end is a plug with a ground wire; when discharging outside the vehicle, one end of the transmission tool cable is connected to the vehicle with an on-board electric gun, and the other end is a socket strip; when performing rescue operations, both ends of the transmission tool cable are on-board electric guns. This causes users to carry multiple transmission tool cables in case of emergency, making it difficult to carry. In addition, it is easy to take the wrong transmission tool cables when storing them together, which also brings inconvenience to use.
[0004] To this end, how to design a three-in-one integrated charging, discharging and rescue system for new energy vehicles, so that it can organize and integrate various transmission tool lines together, so as to facilitate storage and carrying, and at the same time facilitate access, avoiding the inconvenience caused by wrong access or illegal use, is a technical problem that workers in this field need to solve.

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0032] The present invention provides a three-in-one integrated system 10 for charging, discharging and rescuing new energy vehicles, which aims to organize and integrate various transmission tool lines in the prior art, so as to facilitate storage and carrying, and at the same time facilitate access, avoiding the inconvenience caused by wrong access or illegal use.
[0033] like Figure 1 and Figure 2 As shown, the charging, discharging and rescuing three-in-one integrated system 10 includes: a chassis 100, a vehicle-mounted terminal connection device 200, an external terminal connection device 300 and an access restriction device 400. Both sides of the chassis 100 are provided with a receiving cavity 110, and the vehicle-mounted terminal connection device 200 and the external terminal connection device 300 are respectively accommodated in the receiving cavities 110 on both sides. The access restriction device 400 is arranged inside the chassis 100, and the access restriction device 400 is used to fix and restrict the access operation of the external terminal connection device 300 (specifically described below).
[0034] like Figure 3 As shown, the external terminal connection device 300 includes: a discharge socket 310, a charging plug 320 and a rescue charging gun 330, all of which are electrically connected to the controller (not shown) inside the chassis 100 through a wire 301, and the vehicle-mounted terminal connection device 200 is electrically connected to the controller.
[0035] Preferably, a take-up wheel (not shown) is provided in the housing 100. When the wire 301 is stored, the take-up wheel is used to reel in the wire 301; when the wire 301 is taken out, the take-up wheel is used to unwind the wire 301.
[0036] When in use, the user plugs the vehicle-mounted connection device 200 into the charging port of the vehicle, and the vehicle-mounted connection device 200 is directly connected to the vehicle, which adopts the charging gun structure of the prior art. Subsequently, the user selects the external connection device 300 according to the needs. For example, when discharging outside the vehicle, the user takes the discharge socket 310 and plugs the external appliance into the discharge socket 310. At this time, the vehicle serves as a power source to supply power to the external appliance; when charging the vehicle, the user takes the charging plug 320 and stretches the wire 301 so that the charging plug 320 is connected to the external power grid, and then the vehicle is supplemented with power through the external power grid; when performing rescue, the user takes the rescue charging gun 330 and connects it to the charging port of other vehicles, which can supplement power for the power-deficient vehicle.
[0037] It is worth noting that when selecting the external terminal connection device 300, due to differences such as different current transmission directions and different output powers, the vehicle should and can only select one of the working modes. This means that when the external terminal connection device 300 is used, the user should be restricted to only one of them to avoid incorrect use. At the same time, when one of the external terminal connection devices 300 is used, the other two should be locked to avoid multiple uses at a time and incorrect connections. In order to achieve the above functions, the charging, discharging and rescue three-in-one integrated system 10 of the present invention is specially designed with a use restriction device 400.
[0038] Specifically, Figure 4 and Figure 5 As shown, the access restriction device 400 includes: a movable plate 410, a reset elastic member 420 and three groups of linkage components 430. The movable plate 410 is slidably disposed in the chassis 100 through the reset elastic member 420. Three notches 411 are disposed on the movable plate 410, and a deflection lever 412 is disposed at the front end of the movable plate 410. The three notches 411 correspond to the three groups of linkage components 430, and the three groups of linkage components 430 correspond to the charging plug 320, the discharge socket 310 and the rescue charging gun 330.
[0039] like Figure 6 and Figure 7As shown, each linkage assembly 430 includes: a pressure rod 440, a tilting rod 450 and a fastener 460. The pressure rod 440 is provided with a nail 441 that matches the notch 411. The fastener 460 is provided with a slot 461. The movable plate 410 is provided with a latch 413 that matches the slot 461. The tilting rod 450 is rotatably disposed in the chassis 100, and the two ends of the tilting rod 450 respectively abut against the end of the pressure rod 440 and the end of the fastener 460. A buffer spring 442 is provided between the end of the tilting rod 450 and the end of the pressure rod 440.
[0040] The three fasteners 460 are respectively disposed on the discharge socket 310, the charging plug 320 and the rescue charging gun 330. Taking the discharge socket 310 as an example, the connection relationship between it and the fastener 460 is as follows: Figure 8 When the discharge socket 310 is taken, the latch 460 will also be pulled out from the chassis 100.
[0041] Preferably, Figure 7 As shown, the notch groove 411 includes an inclined surface 401, a vertical section 402 and a horizontal section 403. When the clamp 441 is aligned with the inclined surface 401, pressing the pressure rod 440 will cause the clamp 441 to move downward and push the movable plate 410 to compress the resetting elastic member 420; when the clamp 441 is in the horizontal section 403, the pressure rod 440 will be stuck and cannot be lifted.
[0042] In combination with the above structure, the working principle of the access restriction device 400 is described below. Figure 6 and Fig. 9 As shown:
[0043] In the initial state, the discharge socket 310, the charging plug 320 and the rescue charging gun 330 are all accommodated in the accommodating chamber 110. Figure 6 As shown, the pins 441 of the three pressing rods 440 are all located above the notch groove 411, the pins 441 are staggered from the inclined surface 401 and abut against the edge of the movable plate 410. If the pressing rod 440 is pressed at this moment, the pins 441 abut against the movable plate 410, so that the pressing rod 440 cannot be pressed down. At the same time, the latch 413 of the movable plate 410 will be clamped in the clamping grooves 461 of the three clamping members 460, thereby locking the three clamping members 460 to prevent the external terminal connection device 300 from being separated from the accommodating cavity 110;
[0044] Taking the discharge outside the vehicle as an example, first, the user needs to turn the deflection lever 412 to make the movable plate 410 slide as a whole and compress the reset elastic member 420. At this time, the pin 441 of the pressure rod 440 is aligned with the inclined surface 401. Then, the user presses the pressure rod 440 corresponding to the discharge socket 310 to make the pin 441 of the pressure rod 440 enter the notch groove 411 along the inclined surface 401. During this period, the movable plate 410 further slides and compresses the reset elastic member 420. At the moment of being pressed into place, the pin 441 reaches the intersection of the vertical section 402 and the horizontal section 403, and the pin 413 disengages from the slot 461;
[0045] After this moment, two changes occur. First, the tilting rod 450 at this location tilts, and the corresponding latch 460 is lifted up (equivalent to the discharge socket 310 being popped up). The latch slot 461 of the latch 460 is offset from the latch pin 413, and the discharge socket 310 is ready for use. Second, since there is no obstruction from the horizontal staple 441, the reset elastic member 420 extends, and the movable plate 410 slides in the opposite direction under the elastic force until the inner wall of the horizontal section 403 is locked with the staple 441, and the other two latches 460 are again restricted by the latch pin 413. In other words, if Fig. 9 As shown, when the pressure rod 440 is pressed into place, the pressure rod 440 will not reset, the corresponding discharge socket 310 pops up and can be taken, and the charging plug 320 and the rescue charging gun 330 are still locked by the pin 413 and cannot be taken;
[0046] When storing after use, the user returns the discharge socket 310 to its original position, the corresponding latch 460 is inserted and pushes the latch 413 and the movable plate 410 to slide, and the reset elastic member 420 is compressed again. During this period, the tilting rod 450 is deflected and the buffer spring 442 is compressed. When plugged in place, the slot 461 of the latch 460 is aligned with the latch 413, and the corresponding pin 441 of the pressure rod 440 moves to the intersection of the vertical section 402 and the horizontal section 403. After this moment, the pressure rod 440 bounces up under the elastic force of the buffer spring 442, the pin 441 resets back to the top of the notch groove 411, the movable plate 410 is also reset under the elastic force, and the latch 413 locks the latch 460 again. In this way, the discharge socket 310 is re-accommodated in the accommodating cavity 110, and the access restriction device 400 returns to the initial state.
[0047] It can be seen that the access restriction device 400 of the present invention has the following characteristics and beneficial effects:
[0048] On the one hand, it has a good storage locking function, that is, after storage, the external terminal connection device 300 will be locked, so it is not easy to escape from the accommodating cavity 110. At the same time, the locking function also has the effect of preventing accidental touch. For example, in the initial state, even if the pressing rod 440 is accidentally touched, it cannot be pressed down because the pin 441 on it is blocked by the movable plate 410. Only when the deflection lever 412 is moved, the movable plate 410 moves a short distance first, so that the pin 441 is aligned with the inclined surface 401, and the pressing rod 440 can be pressed;
[0049] On the other hand, the use of the external terminal connection device 300 is mandatory and standardized. When taking it, the user can press the corresponding pressure rod 440 for what he needs, and it will not affect other things. For example, after taking the discharge socket 310, the charging plug 320 and the rescue charging gun 330 are still in a locked state. And only when the user resets the discharge socket 310, the charging plug 320 and the rescue charging gun 330 can have a chance to be taken. This avoids the occurrence of wrong connection or multiple taking.
[0050] It should be emphasized that the setting of the buffer spring 442 plays a crucial role. First, the pressure rod 440 moves in a straight line, and the end of the tilting rod 450 moves in an arc. The buffer spring 442, as a flexible component, can be compatible with the different motion trajectories of the two, thereby playing a buffering role in the change process of the access restriction device 400. Secondly, during the reinsertion process of the buckle 460, the buffer spring 442 is compressed, thereby providing the pressure rod 440 with an elastic force to bounce up and reset.
[0051] Preferably, a key cap 443 (such as Figure 7 As shown), the key cap 443 is a plastic structure, and the pressure rod 440 is a metal structure.
[0052] In this embodiment, if Figure 1 and Figure 2 As shown, an interactive panel 120 is provided on the side wall of the chassis 100, and the interactive panel 120 is electrically connected to the controller. A display screen 121 and a control button 122 are also provided on the interactive panel 120, the display screen 121 is used to display the state of the controller during operation, and the control button 122 is used to send instructions to the controller.
[0053] Preferably, the chassis 100 is provided with a hatch 130 (such as Figure 2 As shown in FIG. 1 , the hatch 130 is connected to the chassis 100 through a hinge, and the hatch 130 covers the accommodating chambers 110 on both sides of the chassis 100. The hatch 130 protects the vehicle-mounted terminal connection device 200 and the external terminal connection device 300 in the accommodating chamber 110.
[0054] In other embodiments, the chassis 100 is provided with a handle structure 140 (eg, Figure 2 As shown), it is convenient for users to carry the three-in-one charging, discharging and rescuing system 10, thereby improving its portability.
[0055] To sum up, the three-in-one integrated system 10 for charging, discharging and rescuing of new energy vehicles of the present invention can organize and integrate a variety of existing transmission tool lines together, so as to facilitate storage and carrying, and avoid the inconvenience caused by wrong use or illegal use while facilitating access.
[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
