[0028] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0029] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0031] In related technologies, on-board chargers are usually powered by the cigarette lighter in the vehicle and have a built-in charging cable that can extend and retract. However, the charging cable is prone to jamming during extension and retraction.

[0032] Based on the above, this application provides a vehicle charger 10. Please refer to [link / reference]. Figures 1 to 7 The vehicle charger 10 includes a housing 11, a rotating member 12, a charging cable 13, and a conductive member 14. The housing 11 has a receiving cavity 11a. The conductive member 14 is connected to the housing 11 and is used to draw power from the vehicle. The rotating member 12 is rotatably disposed on the housing 11. The rotating member 12 has a cable outlet 12a. The cable outlet 12a communicates with the receiving cavity 11a. One end of the charging cable 13 is disposed in the receiving cavity 11a and can extend and retract into the receiving cavity 11a through the cable outlet 12a. The other end of the charging cable 13 is connected to a charging head 131. The charging head 131 is exposed outside the housing 11.

[0033] It should be noted that the vehicle charger 10 in this application is a charger powered by the cigarette lighter socket in the vehicle.

[0034] It should be noted that the outer casing 11 is at least used to accommodate the charging cable 13, providing storage space for the charging cable 13.

[0035] For example, the direction of the rotation center axis of the rotating member 12 is not perpendicular to the through direction of the outlet 12a. Here, the direction of the rotation center axis of the rotating member 12 refers to the direction of the rotation center axis of the rotating member 12 during rotation. The through direction of the outlet 12a refers to the opening direction of the outlet 12a on the rotating member 12. The through direction of the outlet 12a can be parallel to or intersect with the direction of the rotation center axis of the rotating member 12; no limitation is imposed here.

[0036] One end of the charging cable 13 is disposed in the receiving cavity 11a and can extend out of and retract into the receiving cavity 11a through the cable outlet 12a. This refers to a portion of the charging cable 13, such as the wire harness 132 portion of the charging cable 13, which can be wound inside the receiving cavity 11a.

[0037] The other end of the charging cable 13 is connected to a charging head 131, which is exposed outside the housing 11. Thus, the charging head 131 is located outside the housing 11, and the user can pull out the wire harness 132 wound and stored in the receiving cavity 11a from the outlet 12a through the charging head 131, thereby facilitating the connection of the charging head 131 to the electronic device for charging.

[0038] For example, one end of the conductive element 14 is used to connect to the cigarette lighter in the vehicle, and the other end of the conductive element 14 is connected to the housing 11.

[0039] Specifically, the vehicle charger 10 also includes a power conversion unit disposed in the receiving cavity 11a. The power conversion unit is capable of converting the power from the cigarette lighter into charging power for electronic devices. The outer surface of the housing 11 is also provided with snap-fit ​​clips for engaging with the cigarette lighter.

[0040] The material of the conductive component 14 can be any conductive material, and there are no restrictions here.

[0041] The rotating member 12 is rotatably disposed on the housing 11, and an outlet 12a communicating with the receiving cavity 11a is formed on the rotating member 12. Thus, the rotating member 12 can rotate adaptively according to the rotation of the charging head 131 of the charging cable 13, or the rotating member 12 can rotate adaptively according to the pulling direction of the wire harness 132 of the charging cable 13. For example, when the user stretches the charging cable 13 extending out of the receiving cavity 11a along R1, the user can rotate the charging head 131 to... Figure 2Then, pull out the charging cable 13 along R1. The flexible rotation of the rotating part 12 allows the outlet 12a to rotate as well, which helps guide the extension and retraction of the cable harness 132 of the charging cable 13, thereby improving the situation where the charging cable 13 is prone to jamming during extension and retraction.

[0042] Understandably, when a user needs to extend the charging cable 13 extending from the receiving cavity 11a along R2, the user can rotate the charging head 131 to... Figure 1 Then pull out the charging cable 13 along R2 to improve the situation where the charging cable 13 is prone to jamming during the extension and retraction process.

[0043] It should be noted that in the embodiments of this application, R1 can be the thickness direction of the outer shell 11, R2 can be the width direction of the outer shell 11, and R3 can be the length direction of the outer shell 11.

[0044] For example, R3 and the charging cable 13 are parallel in the direction of extension and retraction of the receiving cavity 11a through the outlet 12a.

[0045] The vehicle charger 10 provided in this application embodiment rotatably mounts a rotating member 12 onto a housing 11. The rotating member 12 forms an outlet 12a that communicates with a receiving cavity 11a. A portion of the charging cable 13 can extend and retract from the housing 11 through the outlet 12a. Thus, the rotating member 12 can adapt to the rotation of the charging head 131 of the charging cable 13, or it can adapt to the pull-out direction of the cable bundle 132 of the charging cable 13. The flexible rotation of the rotating member 12 allows the outlet 12a to also rotate, which helps guide the extension and retraction of the cable bundle 132 of the charging cable 13, thereby improving the situation where the charging cable 13 is prone to jamming during extension and retraction, and enhancing the flexibility of the product.

[0046] In some embodiments, please refer to Figures 1 to 7 The outer casing 11 has an opening 111a communicating with the receiving cavity 11a. A first rotating part 111b is provided at the opening 111a. The rotating member 12 is provided with a second rotating part 12b. The first rotating part 111b and the second rotating part 12b are rotatably engaged.

[0047] The outer shell 11 has an opening 111a that communicates with the receiving cavity 11a, meaning that the opening 111a is formed on the shell wall of the outer shell 11.

[0048] For example, the opening 111a is circular, the first rotating part 111b is the inner wall surface of the opening 111a on the outer shell 11, and the second rotating part 12b is the outer wall surface of the cylinder formed on the rotating member 12.

[0049] For example, the opening 111a is provided on the shell wall of the housing 11 along the R3 side.

[0050] For example, the opening 111a is provided on the shell wall of the outer casing 11 along the R3 side and is located at one end of the shell wall along the R2 side.

[0051] The first rotating part 111b and the second rotating part 12b are rotatably engaged. For example, the first rotating part 111b and the second rotating part 12b are relative to each other through a bearing.

[0052] In this embodiment, the rotation of the rotating member 12 relative to the outer shell 11 is achieved through the rotational engagement between the first rotating part 111b and the second rotating part 12b. Simultaneously, the first rotating part 111b can also limit the rotation of the rotating member 12 in the radial direction.

[0053] In some embodiments, please refer to Figure 7 A stepped surface 111c is formed at the opening 111a. The stepped surface 111c is used to limit the rotation of the rotating member 12 along the extension and retraction direction of the charging cable 13.

[0054] In this embodiment, the stepped surface 111c can unidirectionally limit the rotation of the rotating member 12. In this way, the situation where the rotating member 12 disengages from the opening 111a of the housing 11 can be improved.

[0055] In some embodiments, please refer to Figure 4 and Figure 5 A stop portion 112a is formed inside the outer casing 11. A rotating member 12 is disposed between the stop portion 112a and the stepped surface 111c.

[0056] In this embodiment, the rotating member 12 is disposed between the stop portion 112a and the stepped surface 111c. That is, the stop portion 112a provides unidirectional limitation for the rotating member 12 on the inner side of the rotating member 12 along the extension and retraction direction of the charging cable 13, and the stepped surface 111c provides unidirectional limitation for the rotating member 12 on the outer side of the rotating member 12 along the extension and retraction direction of the charging cable 13. In this way, bidirectional limitation of the rotating member 12 can be achieved. Combined with the rotational cooperation of the first rotating portion 111b and the second rotating portion 12b, the rotating member 12 is fixed and can also be rotated, which can improve the reliability of the rotating member 12.

[0057] In some embodiments, please refer to Figures 1 to 7 The outer casing 11 includes a housing 111 and a cover 112. The housing 111 has a mounting opening 111d, an opening 111a, a first rotating portion 111b, and a stepped surface 111c. The cover 112 covers the mounting opening 111d to collectively define the receiving cavity 11a. The cover 112 has a stop portion 112a.

[0058] It should be noted that the housing 111 and the cover 112 can be connected by snap-fit.

[0059] Mounting port 111d is formed on the top of housing 111, and mounting port 111d can pass through the wound charging cable 13, thereby facilitating product assembly.

[0060] Here, by dividing the outer shell 11 into a shell 111 and a cover 112, the mounting port 111d, the opening 111a, the first rotating part 111b and the stepped surface 111c are formed on the shell 111, and the stop part 112a is formed on the cover 112. That is to say, one of the parts used to limit the rotation of the rotating part 12 is placed on the cover 112, and the remaining parts used to limit the rotation of the rotating part 12 are placed on the shell 111. This is more conducive to the assembly and fixation of the rotating part 12, and also to the manufacturing process.

[0061] For example, the stop portion 112a consists of two ribs extending from the cover 112 toward the opening 111a. The two ribs extend to both sides of the protrusion and limit the rotation of the member 12.

[0062] In some embodiments, please refer to Figures 1 to 6 The shape of the outlet 12a is adapted to the shape of the charging cable 13 so that the charging cable 13 can drive the rotating part 12 to rotate relative to the outer casing 11 through the outlet 12a.

[0063] For example, the charging cable 13 is flat and the outlet 12a is oblong or rectangular.

[0064] The shape of the outlet 12a is adapted to the shape of the charging cable 13, which can increase the contact area between the charging cable 13 and the edge of the outlet 12a, and increase the area of ​​action of the charging cable 13 on the rotating part 12 during rotation, which is beneficial for the charging cable 13 to drive the rotating part 12 to rotate.

[0065] In some embodiments, the first rotating part 111b and the second rotating part 12b are in clearance fit.

[0066] In this embodiment, the rotating component 12 and the opening 111a of the outer shell 11 are loosely fitted and rotatable. This improves the flexibility of the rotating component 12 and simplifies the rotational fit structure, which is beneficial for production and assembly.

[0067] In some embodiments, the angle between the direction of the rotation center axis of the rotating member 12 and the through direction of the outlet 12a is between 0° and 40°.

[0068] For example, the angle between the direction of the rotation center axis of the rotating member 12 and the through direction of the outlet 12a can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35° or 40°, etc., and is not limited here.

[0069] It should be noted that the direction of the rotation center axis of the rotating component 12 refers to the direction of the rotation center axis of the rotating component 12 when it rotates. The through direction of the cable outlet 12a refers to the opening direction of the cable outlet 12a on the rotating component 12.

[0070] Understandably, in its natural state, i.e. without external force, the extension direction of the portion of the charging cable 13 passing through the outlet 12a is roughly parallel to the through direction of the outlet 12a. By limiting the angle between the direction of the rotation center axis of the rotating member 12 and the through direction of the outlet 12a to between 0° and 40°, the angle between the extension direction and the retraction direction of the portion of the charging cable 13 passing through the outlet 12a and the direction of the rotation center axis of the rotating member 12 in its natural state is between 0° and 40°. This allows the charging cable 13 to pass through the outlet 12a more smoothly, reduces friction with the outlet 12a, facilitates the retraction of the charging cable 13 into the receiving cavity 11a in its natural state, and also facilitates the application of force to the charging cable 13, further improving the situation where the charging cable 13 is prone to jamming during extension and retraction.

[0071] In some embodiments, please refer to Figure 1 and Figure 2 The extension direction of the conductive element 14 is parallel to the extension direction of the charging cable 13.

[0072] It should be noted that the extension direction of the conductive element 14 is parallel to the extension direction of the charging cable 13, and can be completely parallel or approximately parallel, without limitation.

[0073] Understandably, the cigarette lighter in a vehicle is usually located on the center console, facing vertically or at an angle, typically at leg level. When using the car charger, the user usually needs to pull the charging cable upwards. However, in related technologies, the direction of the charging cable's extension / retraction is usually perpendicular to the direction it's pulled out, i.e., perpendicular to the plugging direction of the car charger and cigarette lighter. This means that when pulling out the charging cable, the force applied by the user is perpendicular to the plugging direction of the car charger and cigarette lighter, making it easy for the car charger to detach from the cigarette lighter, thus degrading the user experience.

[0074] In this embodiment, by setting the extension direction of the conductive element 14 to be parallel to the extension direction of the charging cable 13, the direction of pulling out the charging cable 13 is approximately parallel to the extension direction of the charging cable 13. This makes the direction of the force applied by the user when pulling out the charging cable 13 approximately parallel to the insertion direction of the car charger 10 and the cigarette lighter. This improves the reliability of the connection between the car charger 10 and the cigarette lighter during use and enhances the user experience.

[0075] In some embodiments, please refer to Figures 1 to 6 The periphery of the outlet 12a is rounded.

[0076] In this embodiment, by rounding the edges of the outlet 12a, the wear of the outlet 12a on the charging cable 13 can be reduced, thereby improving the product's service life.

[0077] In some embodiments, please refer to Figure 7 The outer casing 11 also has a guide portion 11b, which is located near the opening 111a. The guide portion 11b can guide the extension or retraction of the charging cable 13, reduce the friction or contact force between the charging cable 13 and the rotating part 12 during the extension and retraction process, and improve the durability of the rotating part 12.

[0078] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The outer surface of the housing 11 is provided with a groove 11c near the opening 111a. The vehicle charger 10 also includes a magnetic member 15, which is disposed in the receiving cavity 11a and its position corresponds to the groove 11c.

[0079] Thus, the charging cable 13 of the car charger 10 can also be stored. In the stored state, the charging head 131 of the charging cable 13 is attached to the groove 11c by the magnetic attraction of the magnetic component 15, which can improve the situation of the charging head 131 shaking when the car charger 10 is not in use and enhance the user experience of the product.
