Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted charging seats for electric vehicles, in particular to a vehicle-mounted waterproof automatic telescopic charging device. Background Art

[0002] The location of the charging port of an electric vehicle varies depending on the model and brand. It is generally located at the rear of the vehicle or on the side wall. When a pure electric vehicle is charged with an external charging pile, the charger will generate a lot of heat, and the power battery pack will also generate heat. Therefore, it is necessary to choose a place with good ventilation for charging. Poor ventilation may cause safety hazards due to overheating. In addition, in rainy and snowy weather, try to charge indoors. Since the current on-board charging seat interface and the vehicle body are mostly fixedly connected, although a flip cover is set on the outside for protection, if the long-term sealing measures age or are damaged, the waterproof ability and safety may be reduced. Based on this, a vehicle-mounted waterproof automatic retractable charging device is proposed. Utility Model Content

One side of the fixed plate 14 is rotatably connected to the limit plate 11, and the limit plate 11 is provided with four No. 1 card slots 12. The No. 1 card slots 12 are outward-expanding structures radiating from the inside to the outside. The inner side of each No. 1 card slot 12 is clamped with a card rod 13, and each card rod 13 is fixedly connected to a card plate 16 at one end close to the fixed plate 14. Each card plate 16 is slidably connected to the inner side of the No. 2 card slot 15, and the card plate 16 is limited by the No. 2 card slot 15. The upper side of each card plate 16 is fixedly connected to a waterproof cover plate 17, so that each waterproof cover plate 17 moves back and forth in a fixed direction, and a limit plate rotation mechanism is provided on the side of the fixed plate 14 away from the waterproof cover plate 17.

[0024] Please combine Figure 2 As shown, the limit plate rotation mechanism includes a sleeve 10 fixedly connected to one side of the fixed plate 14, and four curved chute 9 are opened on the inner side of the sleeve 10. It should be noted that the structural distribution of the curved chute 9 is as follows. Figure 6 As shown, the curved chute 9 starts with a straight segment chute and then becomes a quarter-turn spiral chute. The four curved chute 9 are distributed in a circular array, that is, when the sleeve 10 can rotate 90 degrees, a sleeve limiting mechanism is provided on the outside of the sleeve 10, and an insert rod pushing mechanism for pushing the sleeve 10 to rotate is provided inside the sleeve 10.

[0025] Please combine Figure 5As shown, the sleeve limiting mechanism includes a limiting frame 5 rotatably connected to the outer side of the sleeve 10. The limiting frame 5 mainly supports the sleeve 10. The outer side of the limiting frame 5 is fixedly connected to the fixed cylinder 2. The side of the fixed cylinder 2 close to the waterproof cover 17 is fixedly connected to the side of the fixed plate 14, and the limiting plate 11 is rotatably connected to the inner side of the fixed cylinder 2.

[0026] Please combine Figure 5 As shown, the plug rod pushing mechanism includes a cylinder 7 fixedly connected to the inner side of the fixed tube 2. The cylinder 7 has the characteristics of linear movement and high movement distance control accuracy. The moving end of the cylinder 7 is fixedly connected to the charging base unit 4. The outer side of the charging base unit 4 is fixedly connected to 4 plug rods 8. The 4 plug rods 8 are respectively paired with 4 curved slide grooves 9. Each plug rod 8 is slidably connected to the inner side of the curved slide groove 9. A circuit connection mechanism is provided on the outer side of the charging base unit 4.

[0027] Please combine Figure 1 and Figure 3 As shown, the circuit connection mechanism includes a power connection unit 6 fixedly connected to the outside of the charging base unit 4, and a groove 3 is opened on the outside of the fixing tube 2 for the circuit of the power connection unit 6 to pass through.

[0029] The implementation principle of a vehicle-mounted waterproof automatic retractable charging device in the embodiment of the present application is as follows: the charging device is fixedly connected to the body of the electric vehicle through the body docking plate 1. When charging is required, the oil cylinder 7 is started, and the oil cylinder 7 pushes the charging seat unit 4 forward. The insertion rod 8 on the outside of the charging seat unit 4 is inserted into the curved slide groove 9. Due to the spiral structure characteristics of the curved slide groove 9 itself, the insertion rod 8 pushes the sleeve 10 to rotate. The sleeve 10 directly drives the limit plate 11 to rotate, and the rotation of the limit plate 11 can produce the effect of pushing the card rod 13 inward or outward through the first card slot 12. The card rod 13 directly drives the card plate 16 to slide inside the second card slot 15, and indirectly drives each waterproof cover plate 17 to move closer or farther away from each other through multiple card plates 16. When the insertion rod 8 moves to the end of the curved slide groove 9, the multiple waterproof cover plates 17 are in a fully open final state. When the insertion rod 8 is at the head end of the curved slide groove 9, the multiple waterproof cover plates 17 are in a mutually closed state.

[0030] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
