Description

Technical Field

[0001] This utility model relates to the field of power take-off heads for new energy vehicles, and more specifically, to a metal connector for a power take-off head for new energy vehicles. Background Technology

[0002] New energy vehicles are vehicles that use onboard power sources as their power source, driving the wheels through an electric motor. Electric vehicles consist of an electric drive and control system, mechanical systems such as drive transmission, and working devices to perform specific tasks. Electric vehicles use batteries to store electrical energy, which is then converted into mechanical energy by electronic components such as motor controllers and power converters to enable vehicle movement. To meet the external power supply needs of new energy vehicles, an external discharge gun is required to enable the vehicle's discharge function, allowing it to directly supply power to external loads when outdoors.

[0003] Existing discharge plug external devices require wiring through a wiring area, and then connecting to the plug on the electric vehicle through a male connector to draw power, which is inconvenient to operate; moreover, its internal structure is complex, resulting in high cost and cumbersome installation and maintenance.

[0004] A search revealed that Chinese patent CN218887735U discloses a metal connector on a power tap, which facilitates power access to external devices; improves the stability of the relative positional relationship between the socket and the inner core to ensure normal electrical connection and extend service life; and enhances the compatibility of plugs and sockets of external devices, thereby improving practicality.

[0005] When the metal connectors on the aforementioned charging head are not being charged, the charging head is protected by a dust cover. However, some dust covers are only clipped onto the charging head, which can lead to unstable connections. Long-term exposure to unstable dust cover protection can cause the charging head to age faster due to the corrosion of dust and moisture, resulting in poor contact or short circuits, thereby reducing the service life of the charging head. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a metal connector for the power take-off head of a new energy vehicle to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A metal connector for a power take-off head in a new energy vehicle includes a housing, a power take-off head mounted on the front side of the housing, a connecting buckle mounted on the top of the housing, a connecting component mounted on the outer side of the housing, and a sealing mechanism provided between the housing and the outer side of the power take-off head.

[0009] The connecting assembly includes two fixed shells, which are fixedly connected to both sides of the outer shell. A fixed rod is movably connected inside each fixed shell. A rack is fixedly connected to one end of each fixed rod, and a telescopic spring is fixedly connected to one side of the rack. One end of the telescopic spring is fixedly connected to the inside of the fixed shell. A gear meshes with the bottom end of the rack, and a bidirectional screw is fixedly connected inside the gear. The bidirectional screw is rotatably connected to the inside of the fixed shell. Two movable plates are threaded to the outer side of the bidirectional screw. Guide posts are slidably connected to the inner side of each movable plate. Two locking posts are fixedly connected to one side of each movable plate. A connecting rod is slidably connected to the inside of the fixed shell, and the inner side of the connecting rod is inserted into the two locking posts. A dust cover is fixedly connected to one end of the connecting rod, and a first sealing ring is fixedly connected to the inner side of the dust cover. Slip rings are fixedly connected to the other ends of both fixed rods. Two sliding grooves are formed on the outer side of the outer shell, and the slip rings are slidably connected to the inner sides of the sliding grooves.

[0010] By adopting the above technical solution, the dust cover can be stably connected to one end of the power tap, which can protect the fixed shell when the power tap is not in use, thereby helping to protect the power tap and its internal electrical components from contamination and corrosion.

[0011] As a further description of the above technical solution: the sealing mechanism includes a connecting cover, which is fixedly connected to the outside of the power-taking head, a second sealing ring is fixedly connected to the inside of the connecting cover, a cover plate is installed on the inside of the housing, a plurality of sealing lips are fixedly connected to the front side of the cover plate, and a plurality of plug interfaces are installed on one side of the housing.

[0012] By adopting the above technical solution, the connection between the power tap and the vehicle connection part, as well as the connection between the outer shell and the external connector, can be made more tightly connected, which can effectively reduce the infiltration of rainwater and other impurities, thereby ensuring the safety of the connection.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a connection component, compared with the existing technology, the dust cover can be stably connected to one end of the power-taking head, forming a tight sealing structure. This can effectively reduce the entry of dust, moisture and other impurities into the power-taking head, helping to protect the power-taking head and its internal electrical components from pollution and corrosion, thereby extending its service life and reducing charging interruptions or charging speed reductions caused by poor contact.

[0015] 2. By setting a sealing mechanism, compared with the existing technology, the power take-up head can be more tightly connected to the car connection part and the outer shell to the external connector, which enhances the stability of the electrical connection and can reduce the leakage of external rainwater during the connection process, thereby ensuring the stability and safety of the connection.

Two movable plates 10 are threadedly connected to the outside of the double-acting screw 9. Guide posts 11 are slidably connected to the inside of the movable plates 10. Two locking posts 12 are fixedly connected to one side of the movable plates 10. A connecting rod 13 is slidably connected to the inside of the fixed shell 4, and the inside of the connecting rod 13 is inserted into the two locking posts 12. A dust cover 14 is fixedly connected to one end of the connecting rod 13, and a first sealing ring 15 is fixedly connected to the inside of the dust cover 14. Slip rings 16 are fixedly connected to the other ends of both fixed rods 5. Two openings are provided on the outside of the outer shell 1. A sliding groove 17 is provided, and a sliding ring 16 is slidably connected to the inner side of the sliding groove 17. The movement of the sliding ring 16 can drive the rack 6 to move through two fixed rods 5. The two sliding grooves 17 can provide guidance for the movement of the sliding ring 16. The movement of the rack 6 can mesh with and drive the gear 8 to rotate, so that the gear 8 can drive the bidirectional screw 9 to rotate. The bidirectional screw 9 can drive the movable plate 10 to move through the thread. The guide post 11 can provide guidance for the movement of the bidirectional screw 9, so that the movable plate 10 can stably drive the two locking posts 12 to move, so that the two locking posts 12 can be inserted or separated from the connecting rod 13, thereby facilitating the installation and removal of the dust cover 14 and facilitating the stable connection between the dust cover 14 and the power take-up head 2. The first sealing ring 15 can form a tight sealing structure between the dust cover 14 and the power take-up head 2, thereby effectively reducing the entry of dust, moisture and other impurities into the power take-up head 2, thereby extending its service life.

[0028] Working principle of this utility model: This utility model designs a metal connector for a power take-off head in a new energy vehicle, the specific structure of which is shown in the attached instruction manual. Figures 1-7As shown, in this technical solution, through the cooperation between various structures, when the power-taking head 2 needs to be used, the slip ring 16 is first pulled. The slip ring 16 is slidably connected to the inner sides of the two sliding grooves 17, allowing the slip ring 16 to stably pull the rack 6 via the fixed rod 5. One end of the rack 6 can pull the telescopic spring 7 inside the fixed housing 4. The two telescopic springs 7 facilitate the rack 6 to return to its original position when the slip ring 16 is not pulled. Simultaneously, the rack 6 can mesh with and drive the gear 8 to rotate, allowing the gear 8 to drive the bidirectional screw 9 to rotate. This allows the bidirectional screw 9 to drive the two movable plates 10 to move via threads with opposite directions. The guide post 11 provides guidance for the movement of the two movable plates 10, enabling the two movable plates 10 to move... The two locking pins 12 are separated from the connecting rod 13. Then, the dust cover 14 is removed from one end of the power take-up head 2, and the power take-up head 2 is inserted into the car connection. The extension of the connecting cover 18 can block the gap between the power take-up head 2 and the car connection. Through the function of the connecting cover 18, the power take-up head 2 can be tightly connected to the car connection and provide a certain degree of sealing. When the external plug needs to be connected to the plug interface 22 on one side of the outer casing 1, multiple sealing lips 21 on the front side of the cover plate 20 can fill the gap between the external plug and the cover plate 20 when the external plug is connected to the plug interface 22, thereby reducing the leakage of external rainwater into the plug interface 22 and helping to maintain the safety of the connection.
