Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted power chargers, and particularly relates to a vehicle-mounted power charger with a guiding structure. Background Art

[0002] With the development of the automotive industry, vehicle-mounted chargers are widely used and exhibit the characteristics of versatility, portability, and fashionability. A vehicle-mounted charger refers to a charger that is conventionally powered by an automotive battery (12V for cars and 24V for trucks), and is widely used in the field of lithium battery charging for various portable and handheld devices.

[0003] When the data cable (with a circular cross-section) of the existing vehicle-mounted charger is not in use, if it is to be stored in the cable storage structure inside the charger, a large frictional force will be generated between the data cable and the pulley structure that guides the data cable inside during the pulling process, resulting in a poor experience. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a vehicle-mounted power charger with a guiding structure, which has the advantages of avoiding the situation where the flat data cable is always dragged in the external environment, which can not only be more beautiful but also avoid damage to the flat data cable, and solves the problems that the data cable of the existing vehicle-mounted charger is not beautiful and easily damaged.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A vehicle-mounted power charger with a guiding structure includes a rear cover body, a front cover body attached to the opening of the rear cover body, and a vehicle-mounted charging component located inside the rear cover body. The vehicle-mounted charging component includes a circuit board fixedly installed at the bottom of the inner cavity of the rear cover body, a movable power supply interface and a plurality of fixed power supply interfaces connected to the circuit board. A protective shell is fixed on one side of the inner cavity of the rear cover body;

[0006] A flat data cable connected to the movable power supply interface is also provided in the inner cavity of the rear cover body. An outer pulley and an inner pulley that can rotate freely are also provided in the inner cavity of the rear cover body. The flat data cable passes through the bottom of the inner pulley and the top of the outer pulley and then extends out from an opening on one side of the bottom of the rear cover body. A part of the flat data cable is wound inside the protective shell.

[0007] As a preferred implementation: A power supply line coupled to the circuit board is connected above the rear cover body.

[0008] As a preferred implementation: A plurality of ear plates are fixedly connected to the protective shell. All the ear plates are attached to the inner wall of the rear cover body, and all the ear plates are fixed inside the rear cover body by screws.

[0009] As a preferred embodiment: A socket is formed at the bottom of the rear cover body, and the movable power supply interface is vertically inserted into the socket.

[0010] As a preferred embodiment: An outer connecting cap and an inner connecting cap are fixedly bonded in the front cover body. The outer pulley slides into the outer connecting cap, and the inner pulley slides into the inner connecting cap.

[0011] As a preferred embodiment: A plurality of buckles are fixedly connected to the outer circumference of the front cover body, and a structure adapted to be snap-connected with the plurality of buckles is provided in the inner cavity of the rear cover body.

[0012] As a preferred embodiment: An included angle a is formed between the outer pulley and the inner pulley, and the angular value of the included angle a is between 5° and 20°.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, by designing the protective shell and the structure inside the protective shell, when the movable power supply interface needs to be used, it is stretched to the outside together with the flat data cable. During the process of pulling out the flat data cable, due to the included angle between the outer pulley and the inner pulley, and the flat data cable is in a flat shape instead of the common circular shape, the frictional force when the flat data cable rubs against the outer pulley and the inner pulley is greatly reduced. Therefore, it can be more labor-saving and there will be no inconvenience in pulling out the flat data cable due to too large frictional force, improving the experience when pulling out the flat data cable. When using the flat data cable to charge the device externally, grasping the charging port of the flat data cable can smoothly pull it out, making the flat data cable shrink, lengthen, or shorten, and consumers can experience the ultimate ergonomic feel.

[0024] Please refer to Figures 1 to 6, an embodiment provided by the present utility model: a vehicle-mounted power charger with a guiding structure, including a rear cover body 1, a front cover body 2 attached to the opening of the rear cover body 1, and a vehicle-mounted charging assembly located inside the rear cover body 1. A plurality of buckles 12 are fixedly connected to the outer circle of the front cover body 2, and a structure adapted to be snap-connected to the plurality of buckles 12 is provided in the inner cavity of the rear cover body 1, so that the plurality of buckles 12 can be snap-connected into the rear cover body 1, and the rear cover body 1 and the front cover body 2 are combined into one. The vehicle-mounted charging assembly includes a circuit board 6 fixedly installed at the bottom of the inner cavity of the rear cover body 1, a movable power supply interface 5 and a plurality of fixed power supply interfaces 4 connected to the circuit board 6. Among them, the plurality of fixed power supply interfaces 4 include common interfaces such as TYPE-A and TYPE-C, and the movable power supply interface 5 is a TYPE-C interface. An insertion port is formed at the bottom of the rear cover body 1, and the movable power supply interface 5 is vertically inserted into the insertion port, so that the movable power supply interface 5 can be stored in the insertion port when not in use, and can be directly taken out by pinching the movable power supply interface 5 when needed. A power supply line 3 coupled to the circuit board 6 is connected above the rear cover body 1, so that the circuit board 6 and all the power components thereon are powered by the power supply line 3;

[0025] A protective shell 7 is fixed on one side of the inner cavity of the rear cover body 1. In order to fix the protective shell 7, a plurality of ear plates 8 are fixedly connected to the protective shell 7. The plurality of ear plates 8 are all attached to the inner wall of the rear cover body 1, and the plurality of ear plates 8 are all fixed in the rear cover body 1 by screws, so that the structure of the protective shell 7 is kept stable. Similarly, the circuit board 6 can also be fixed in the manner of the prior art. The inside of the protective shell 7 is designed to be hollow. A flat data line 9 (the cross-section of the common data line in the prior art is circular) connected to the movable power supply interface 5 is also provided in the inner cavity of the rear cover body 1. An outer pulley 10 and an inner pulley 11 that can rotate freely are also provided in the inner cavity of the rear cover body 1. The flat data line 9 passes through the bottom of the inner pulley 11 and the top of the outer pulley 10 and then extends out from an opening on one side of the bottom of the rear cover body 1. An outer connection cap 13 and an inner connection cap 14 are fixedly bonded in the front cover body 2. The outer pulley 10 is slidably inserted into the outer connection cap 13, and the inner pulley 11 is slidably inserted into the inner connection cap 14, so that the two outer pulleys 10 can rotate freely in the outer connection cap 13 and the inner connection cap 14. A part of the flat data line 9 is wound in the protective shell 7. The included angle between the outer pulley 10 and the inner pulley 11 is a, and the range of a is 5° to 20°. In the Figure 5 shown embodiment, this angle is 15°. With the help of this included angle, the friction between the flat data line 9 and the outer pulley 10 (and the inner pulley 11) can be reduced.

[0026] Working principle: When the utility model is in use, (the overall structure of the rear cover body 1 and the front cover body 2 is fixed inside the vehicle and cannot be moved). The side where the fixed power supply interface 4 and the movable power supply interface 5 are located directly faces the vehicle interior. If the fixed power supply interface 4 needs to be used, the user only needs to insert the corresponding USB interface into the fixed power supply interface 4 to perform corresponding charging. If the movable power supply interface 5 needs to be used, reach out and pinch the movable power supply interface 5 and stretch the flat data cable 9 outwards. The flat data cable 9 will be gradually pulled out of the protective shell 7 and extend out of the rear cover body 1 along the movable power supply interface 5 under the guidance of the outer pulley 10 and the inner pulley 11, so as to facilitate the personnel inside the vehicle to insert the movable power supply interface 5 into mobile devices such as mobile phones and tablets, so that charging can be carried out in real time without affecting the use of the device. When the movable power supply interface 5 does not need to be used, the flat data cable 9 is stored in the protective shell 7, and then the movable power supply interface 5 is inserted into its designated socket, which is simple and convenient to operate. When charging the device with the flat data cable 9 externally, grasping the movable power supply interface 5 of the flat data cable 9 can smoothly pull and draw, making the flat data cable 9 contract and extend, and consumers can experience the ultimate ergonomic feel.
