Description

TECHNICAL FIELD

[0002] With the rapid development of autonomous driving technology, autonomous vehicles are increasingly widely used in many fields such as logistics transportation, shared travel, and urban distribution. These vehicles usually need to run continuously for a long time, which puts unprecedented high requirements on the convenience, efficiency and reliability of charging. As a key component to ensure the normal operation of autonomous vehicles, the performance of the charging device directly affects the user experience and operational efficiency of the vehicle.

[0003] In existing autonomous vehicle charging devices, there is a lack of effective sealing design at the charging port. When the vehicle is in an outdoor environment, dust, rainwater, sand and other impurities can easily enter the charging port. The accumulation of dust and sand may cause poor contact of the charging interface, affecting the charging efficiency, and even causing safety hazards such as short circuits. The intrusion of rainwater may directly damage the electronic components inside the charging device, causing equipment failure, increasing maintenance costs and downtime. At the same time, most existing charging device plug installation structures are simple, only using hanging or friction force fixation, which can easily cause the plug to fall off or even fall to the ground, causing damage to the plug. Although some charging devices use some fixing measures, the operation process is complex, which not only increases the user's operation difficulty and time cost, but also easily causes equipment damage due to improper operation. Moreover, in an emergency, the complex operation process may delay the charging time, affecting the scheduling and use efficiency of the vehicle.

[0052] The working principle of the charging device for the automatic driving vehicle provided by the application is as follows:

[0053] When the charging plug 151 needs to be taken out for charging the car, the charging plug 151 is slightly pushed to move the sealing plate 231 backward, at this time, the sealing plate 231 drives the two side toothed plates 2362 to move, so that the recesses 2363 of the toothed plates 2362 are aligned with the gear 244, the toothed plates 2362 no longer limit the gear 244, the gear 244 is turned by 90 degrees under the elastic force of the coil spring 247, so that the clamping block 248 and the buckle 245 are loosened to limit the charging plug 151, the charging plug 151 that loses the limitation can be pulled out from the interface shell 211 by slight force, with the charging plug 151 being separated, the sealing plate 231 moves outward synchronously under the extrusion of the spring 223, and is lapped with the inner side of the sealing ring 216, so that the sealing of the interface shell 211 is completed;

[0054] After the charging is completed, the charging plug 151 is inserted into the mounting groove 212 in the interface shell 211 again, as the charging plug 151 gradually extends, it synchronously extrudes the sealing plate 231 to move backward, at the same time, the sealing column 233 on the surface of the sealing plate 231 is inserted into the corresponding charging hole of the charging plug 151, as the charging plug 151 continuously pushes the sealing plate 231, the gear 244 is turned over by the tooth plate 2362, when the buckles 245 and the clamping blocks 248 on both sides are clamped into the clamping grooves 153 on both sides of the charging plug 151, the charging plug 151 is loosened, at this time, the sealing plate 231 is extruded by the elastic force of the rear spring 223, and the charging plug 151 is pushed to move outward, but the charging plug 151 is limited by the buckles 245 and the clamping blocks 248, and will be further attached to them, so that the fixing of the charging plug 151 is completed, in the process, the telescopic sleeve 221 is contracted, the air in the telescopic sleeve 221 is extruded into the connecting box 235 along the communication pipe 222, and the gas enters the sealing columns 233 and the expansion rings 234, so that the inside of the charging port 13 of the charging plug 151 is protected, and dust and impurities are prevented from entering;

[0055] After the charging plug 151 is taken out, the sealing plate 231 is attached to one side of the sealing ring 216 under the extrusion of the spring 223, and the tooth plate 2362 is pushed to move, so that the recess 2363 on the other side of the tooth plate 2362 is moved to the position of the gear 244, and the tooth plate 2362 is reset under the elastic force of the coil spring 247.

[0056] Compared with the related art, the charging device for the autonomous vehicle has the following beneficial effects:

[0057] After charging, the charging plug 151 needs to be inserted into the mounting groove 212 in the interface shell 211 again. As the charging plug 151 gradually extends into the mounting groove 212, it will synchronously extrude the sealing plate 231 to move backward. In this process, the sealing column 233 on the surface of the sealing plate 231 will be inserted into the corresponding charging hole of the charging plug 151. As the charging plug 151 continuously pushes the sealing plate 231 to move, the tooth plate 2362 will drive the gear 244 to flip. When the buckles 245 and the clamping blocks 248 on both sides are clamped into the clamping grooves 153 on both sides of the charging plug 151, the charging plug 151 is loosened. At this time, the sealing plate 231 is extruded by the elastic force of the rear spring 223 and will push the charging plug 151 to move outward, but the charging plug 151 is limited by the buckles 245 and the clamping blocks 248 and will further fit with them, thereby completing the fixation of the charging plug 151. In this process, the telescopic sleeve 221 contracts and extrudes the air in its interior to the connecting box 235 along the communication pipe 222. Subsequently, the gas enters the sealing columns 233 and the expansion rings 234 and plays a protective role on the inside of the charging port 13 of the charging plug 151, avoiding the entry of dust and impurities. In this way, the device can obtain stable fixation effect after being placed and prevent the charging plug 151 from falling off, improve the protection effect of the charging plug 151, and at the same time, the sealing columns 233 and the sealing ring 216 extend into the charging port 13 and expand, which can effectively prevent dust, moisture and other impurities from entering the charging port 13, avoid damage or charging failure of the charging interface caused by the entry of impurities, prolong the service life of the charging device, and improve the safety and reliability of charging.

[0058] After the charging plug 151 is taken out, the sealing plate 231 will fit with one side of the sealing ring 216 under the extrusion of the spring 223. At the same time, the sealing plate 231 will synchronously push the tooth plate 2362 to move, so that the recess 2363 on the other side of the tooth plate 2362 moves to the position of the gear 244, allowing the tooth plate 2362 to reset under the elastic force of the coil spring 247. In this way, it can be ensured that the buckles 245 and the clamping blocks 248 can reset after the charging plug 151 is taken out each time, thereby effectively limiting and fixing the charging plug 151 during subsequent installation.

[0059] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process conversion using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
