DETAILED DESCRIPTION
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0031] Reference Figure 1-Figure 5 As shown, the utility model discloses a portable new energy vehicle discharge gun, comprising:
[0032] Shell 1;
[0033] The plug part 2 includes a gun head 27, a signal terminal 22 and a plurality of power supply terminals 21. One end of the gun head 27 is snap-fitted with one end of the housing 1. The plurality of power supply terminals 21 and the signal terminal 22 are all disposed inside the gun head 27.
[0034] The socket part 3 includes a discharge socket panel 31, a self-resetting overload protector 32 and a plurality of clips 33. The discharge socket panel 31 is clamped inside the housing 1; one end of the plurality of clips 33 is electrically connected to the power supply terminal 21, and the other end of the clip 33 is passed through the discharge socket panel 31. The self-resetting overload protector 32 is connected in series between the power supply terminal 21 and the clip 33.
[0035] In the utility model, the gun head 27 and the shell 1 are spliced to form the appearance of the entire discharge gun, wherein one end of the plug part 2 is connected to the discharge port of the new energy vehicle, and one end of the socket part 3 is used to plug in the load. Specifically, the power supply terminal 21 in the plug part 2 is adapted to the discharge port of the car, and the signal terminal 22 is used to detect the power consumption signal and feed the signal back to the new energy vehicle to ensure normal discharge. The discharge seat panel of the socket part 3 is directly connected to the electrical equipment, and the corresponding discharge socket panel 31 is selected according to the standard of the electrical equipment; the clip 33 is electrically connected to the power supply terminal 21, and the positions of the multiple clips 33 correspond to the interface positions on the surface of the discharge seat panel, so that the power supply terminal 21 is transmitted to one side of the discharge seat panel. During use, the plug of the electrical equipment is connected to the clip 33 to transmit the power of the new energy vehicle to the load. In the utility model, the self-resetting overload protector 32 is connected in series between the power supply terminal 21 and the clip 33. Specifically, the self-resetting overload protector 32 can realize the function of automatic power-off and power-on according to the usage status of the load. Its working principle is to judge the usage status of the load according to the change of temperature. When the power at the load end exceeds the rated power, the self-resetting overload protector 32 detects the temperature rise of the line and then cuts off the power supply. When the temperature returns to below the rated value, the connection is automatically restored.
[0036] The utility model connects the self-recovery overload protector 32 in series between the power supply terminal 21 and the clip 33 to detect the load power of the discharge gun during use, thereby avoiding accidents such as fire caused by short circuit or excessive discharge power during use of the discharge gun and overheating of the discharge gun.
[0037] Furthermore, a fixing frame 28 is provided in the gun head 27 , and the power supply terminal 21 and the signal terminal 22 are clamped in the fixing frame 28 .
[0038] Specifically, the function of the fixing frame 28 is to fix the power supply terminal 21 and the signal terminal 22 in cooperation with the gun head 27. The fixing frame 28 is provided with an installation bayonet that cooperates with the power supply unit and the signal terminal 22 to ensure the stability of the power supply terminal 21 and the signal terminal 22 during use.
[0039] Furthermore, the power supply terminal 21 includes a neutral terminal 211 , a live terminal 212 and a ground terminal 213 , and the self-resetting overload protector 32 is disposed between the live terminal 212 and the clip 33 .
[0040] Specifically, the live wire is the main power line, and connecting it to the self-resetting overload protector 32 can conveniently protect the electrical equipment; the self-resetting overload protector 32 can monitor the current on the live wire by connecting it to the live wire terminal 212. When the current exceeds the set safety limit, the protector will automatically cut off the circuit to prevent the current overload from damaging the circuit and electrical equipment.
[0041] Furthermore, a circuit board 24 is disposed inside the gun head 27 , one end of the circuit board 24 is electrically connected to the signal terminal 22 , and the other end of the circuit board 24 is electrically connected to the ground terminal 213 .
[0042] Specifically, the function of the signal terminal 22 is to detect whether the discharge gun is working properly. The ground wire, as a return path for the electrical signal, can provide a stable reference potential for the signal, thereby reducing signal interference and errors. In addition, when the signal terminal 22 is connected to the ground wire, static electricity or electromagnetic interference that may exist on the signal terminal 22 can be effectively discharged, further enhancing the stability of the signal. At the same time, the ground wire can also play a shielding role, reducing the interference of external electromagnetic fields on the signal.
[0043] Furthermore, a first sealing ring 25 is provided at the joint between the gun head 27 and the housing 1. A second sealing ring 34 is provided between the discharge socket panel 31 and the housing 1.
[0044] Specifically, the first sealing ring 25 is arranged at the joint between the gun head 27 and the shell 1 to prevent moisture from entering the entire discharge gun through the gap between the two. The second sealing ring 34 is arranged at the joint between the discharge socket panel 31 and the shell 1 to prevent moisture from entering through the gap between the two, thereby improving the sealing of the entire discharge gun.
[0045] Furthermore, a third sealing ring 26 is provided between the signal terminal 22 and the power supply terminal 21 and the gun head 27. Specifically, since one end of the signal terminal 22 and the power supply terminal 21 is directly exposed to the outside, a third sealing ring 26 is sleeved on the outer side of each signal terminal 22 and the power supply terminal 21, and the third sealing ring 26 can prevent moisture from entering the inside of the discharge gun through the gap between the terminal and the gun head 27.
[0046] As a preferred solution of the utility model, a sealing plug 23 is provided at one end of the fixing frame 28 close to the housing 1, and the signal terminal 22 and the power supply terminal 21 are inserted into the sealing plug 23; the sealing plug 23 is provided at one end of the signal terminal 22 and the power supply terminal 21 away from the port of the gun head 27, and the sealing plug 23 and the signal terminal 22 and the power supply terminal 21 are interference fit, which further forms a seal to prevent water vapor from entering the interior of the discharge gun, thereby improving the insulation effect of the entire discharge gun.
[0047] Furthermore, an isolation cabin 35 is further provided inside the housing 1 , the isolation cabin 35 is provided close to the discharge socket panel 31 , and the clip 33 is passed through the isolation cabin 35 ; a fourth sealing ring is provided between the isolation cabin 35 and the discharge socket panel 31 .
[0048] Specifically, since the surface of the discharge socket is provided with a socket for matching the load plug, an automatic closing hole corresponding to the position of the socket is provided on the side of the isolation cabin 35 close to the discharge socket panel 31. The plug end of the load passes through the socket into the automatic closing hole and is connected to the clip 33. After the plug is unplugged, the automatic closing hole is closed, which can effectively prevent short circuits caused by the entry of impurities such as dust from the outside; secondly, the fourth sealing ring can prevent moisture from entering from the joint between the isolation cabin 35 and the discharge socket panel 31.
[0049] As a preferred solution of the utility model, the discharge socket panel 31 is detachably connected to the housing 1. According to the implementation standards of different countries and regions, different discharge socket panels 31 can be replaced to meet different load plugs. Similarly, the entire plug part 2 as a whole can also be replaced, and the national standard port and the European standard port can be selected according to the different discharge ports of the vehicle. Specifically, Figure 6 As shown, the inside of the housing 1 is a French standard discharge socket panel 31, which is suitable for electrical equipment with French standard plugs; Figure 7 As shown, the interior of the housing 1 is a British standard discharge socket panel 31, which is suitable for electrical equipment with British standard plugs; Figure 8 As shown, the interior of the housing 1 is a German standard discharge socket panel 31, which is suitable for electrical equipment with German standard plugs.
[0050] Furthermore, the gun head 27 is provided with a plurality of buckles 271 in the circumferential direction of one end away from the housing 1. Specifically, during use, the end of the gun head 27 provided with the buckle 271 is inserted into the discharge interface of the car, and cooperates with the block in the discharge interface of the car to ensure the stability of the discharge gun connection.
[0051] In summary, the utility model introduces a portable new energy vehicle discharge gun, one end of which is connected to the discharge port of the vehicle, and the other end of which is used to adapt to the plug of the load. The utility model detects the power of the load of the discharge gun during use by connecting the self-recovery overload protector 32 in series between the power supply terminal 21 and the clip 33, thereby preventing the discharge gun from causing an excessive load on the battery due to a short circuit or excessive discharge power during use, reducing damage to the battery, and extending the battery life; secondly, it can also prevent accidents such as fire caused by excessive temperature of the discharge gun.
