[0002] A car charger is a DC input charger with a charging plug designed to resemble a cigarette lighter plug. Plug the car charger into the car's cigarette lighter socket and connect it directly to the car's battery to obtain power. This allows mobile multimedia devices to be charged using the car's power supply, increasing the number of charging locations for mobile multimedia devices. It also has a compact and portable structure. It's important to note that the appropriate temperature for using a car charger is between 0 and 45 degrees Celsius. When not in use, especially in hot summer, the car charger needs to be removed from the cigarette lighter socket and taken with you when leaving the car.

[0003] Existing car chargers are also provided with a pulling structure on the top, such as a pull ring, etc. However, the pull ring of the existing car charger is movable on the top of the car charger. When the car charger is not in use, taken out of the cigarette lighter socket, or placed in a bag, if the car charger is tilted or placed horizontally, the pull ring will be lifted up. If it is stuck or tangled with other objects, the pull ring is easily damaged.

[0004] Therefore, it is necessary to provide a new vehicle charger with a pulling structure to solve the above technical problems. Utility Model Content

Specific embodiments

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Please refer to Figures 1-5 , where Figure 1 is a schematic structural diagram of a vehicle-mounted charger with a lifting structure provided by the present utility model; Figure 2 is Figure 1 another state diagram shown; Figure 3 is Figure 1 a schematic structural diagram of the PCB circuit board shown; Figure 4 is Figure 2 a schematic structural diagram of the positioning device shown; Figure 5 is Figure 4 another state diagram of the positioning device shown.

[0022] In the specific implementation process, as Figures 1-5 shown, a vehicle-mounted charger with a lifting structure includes an outer shell 1, a pull ring 2 and a positioning device. Auxiliary rods are fixedly connected to both sides of the top of the outer shell 1. Both ends of the pull ring 2 are rotatably connected to the two auxiliary rods. The positioning device is fixedly installed in the middle of the pull ring 2. The middle of the pull ring 2 is detachably connected to the outer shell 1 through the positioning device;

[0023] The positioning device includes a fixed column 5, which is fixedly connected to the middle of the pull ring 2. A pull rod 10 is slidably connected in the fixed column 5. The top of the pull rod 10 is fixedly connected to a handle 9. In order not to let the vehicle charger affect the driver's gear shifting, the vehicle charger is usually completely set in the cigarette lighter socket. The handle 9 plays a role in facilitating the taking and placing of the vehicle charger. At the same time, the handle 9 also plays a role in preventing the pull rod 10 from falling off the bottom of the fixed column 5. The bottom of the pull rod 10 is fixedly connected to a connecting plate 7. The lower end of the connecting plate 7 is fixedly connected to a limiting block 16. An installation groove 8 is opened on one side of the top of the housing 1, so that the limiting block 16 can extend into it. A mounting plate 12 is fixedly connected to one side wall of the installation groove 8. At both ends of the front side of the mounting plate 12, limiting members are fixedly connected in opposite directions. The limiting block 16 can extend between the two limiting members.

[0024] The limiting member includes a receiving frame 13. A spring 14 is arranged in the receiving frame 13. One end of the spring 14 is fixedly connected to the inner side wall of the receiving frame 13. The other end of the spring 14 is fixedly connected to a limiting ball 15. The limiting block 16 can extend between two opposite limiting balls 15. When the limiting ball 15 is squeezed, the limiting ball 15 can drive the spring 14 to contract. When the limiting ball 15 is no longer squeezed, the spring 14 will bring the limiting ball 15 back to its original position.

[0025] The limiting block 16 is arranged with a concave middle part and convex upper and lower ends, and the edges of the concave part and the convex part are all smoothly arranged. The middle concave part is adapted to the limiting ball 15, and the distance between two opposite limiting balls 15 is less than the width of the convex part at the bottom end of the limiting block 16. When it is necessary to fix the pull ring 2 at the top of the housing 1, press down the pull rod 10. At this time, the limiting ball 15 is squeezed by both sides of the convex part at the lower end of the limiting block 16, and at the same time, the limiting ball 15 squeezes the spring 14 inward. When the limiting block 16 continues to move downward, when the concave part of the limiting block 16 moves to be adapted to the limiting ball 15, the spring 14 rebounds due to its natural elastic force, driving the limiting ball 15 to move towards the concave part of the limiting block 16, thereby achieving the limiting effect on the pull ring 2.

[0026] An interface 6 is arranged on the top of the housing 1. Two negative electrode holes 11 are opened on the side wall of the housing 1. A PCB circuit board 17 is arranged inside the housing 1. The interface 6 is electrically connected to the PCB circuit board 17. The positive electrode and the negative electrode on the PCB circuit board 17 are respectively electrically connected to a positive electrode connector 4 and two negative electrode bumps 3. The positive electrode connector 4 passes through the bottom of the housing 1, and the negative electrode bumps 3 pass through the negative electrode holes 11.

[0027] The two negative electrode bumps 3 are connected by an arc-shaped conductive connecting piece 18.

[0028] A trapezoidal elastic piece 19 is arranged between the negative electrode bump 3 and the PCB circuit board 17. The bottom end of the trapezoidal elastic piece 19 is welded to the negative electrode of the circuit board, and the top end of the trapezoidal elastic piece abuts against the negative electrode bump 3.

[0029] The working principle provided by the present utility model is as follows: For the vehicle-mounted charger with a lifting structure, during specific implementation, hold the pull ring 2, align the positive connector 4 at the bottom of the vehicle-mounted charger with the cigarette lighter socket in the vehicle, and place it downward. After ensuring correct placement, release the pull ring 2. At this time, the pull rod 10 and the limit block 16 move downward along with the pull ring 2 until the limit block 16 extends into the installation groove 8. When the limit block 16 moves to the top of the limit ball 15, continue to press downward. At this time, the limit ball 15 is squeezed by the protrusions on both sides of the lower end of the limit block 16, and at the same time, the limit ball 15 squeezes the spring 14 inward. Refer to Figure 5 , when the limit block 16 continues to move downward, when the recessed part of the limit block 16 moves to adapt to the limit ball 15, the spring 14 rebounds due to its natural elastic force, driving the limit ball 15 to move towards the recessed part of the limit block 16, thereby achieving the limiting effect on the pull ring 2. Refer to Figure 4 , then the vehicle-mounted charger can be used. After use or when the user leaves the vehicle, the vehicle-mounted charger needs to be taken out and carried away. Especially in the hot summer, at this time, the handle 9 on the pull ring 2 can be held to take it out of the cigarette lighter socket. When the vehicle-mounted charger needs to be hung somewhere, hold the outer shell 1 with one hand and pull the handle � with the other hand. The limit block 16 is subjected to an upward force, and the limit block 16 will squeeze the limit ball 15, driving the spring 14 to contract until the limit block 16 moves out from between the two limit balls 15, and then the middle part of the pull ring 2 can be separated from the outer shell 1.

[0030] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here too much.

[0031] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
