[0042] Embodiments of the present application provide a vehicle charger 1.

[0043] The vehicle charger 1 is a device for connecting a mobile device to a vehicle for charging on the vehicle, and the mobile device can be a mobile phone or a tablet computer.

[0044] Referring to Figures 1 to 7 The vehicle charger 1 comprises a connection module 10 and a telescopic module 11.

[0045] The bottom side of the connection module 10 is formed with a connection port 10a for electrical connection with the vehicle. The telescopic module 11 is arranged on the top side of the connection module 10.

[0046] That is, the vehicle charger 1 is plugged into the interface of the vehicle through the connection port 10a to achieve electrical connection between the vehicle charger 1 and the vehicle. For example, the connection module 10 is electrically connected with the cigarette lighter socket of the vehicle.

[0047] The telescopic module 11 is arranged on the top side of the connection module 10, i.e. on the side of the connection module 10 away from the connection port 10a, so that the telescopic module 11 does not interfere with the electrical connection between the connection port 10a and the vehicle, and it is also convenient to arrange the charging cable on the telescopic module 11.

[0048] Specifically, the telescopic module 11 comprises a housing 111 and a telescopic charging cable 112. The housing 111 has an opening, one end of the telescopic charging cable 112 is arranged in the housing 111 and is electrically connected with the connection port 10a, and the other end is exposed to the outer surface of the vehicle charger 1 through the opening. The telescopic charging cable 112 is used for plugging charging.

[0049] That is, the telescopic charging cable 112 obtains the electrical energy transmitted from the interface of the vehicle through the connection port 10a. One end of the telescopic charging cable 112 obtains the electrical energy in the housing 111, and the other end is exposed to the outer surface of the vehicle charger 1 through the opening, i.e. can be seen by the user, so as to facilitate charging.

[0050] It can be understood that the electrical connection mode of the telescopic charging cable 112 with the connection port 10a is not limited, which can be directly through the cable or through the combination of the cable and the circuit board, which is not limited here.

[0051] It can be understood that the telescopic charging cable 112 here refers to a charging cable that can freely extend within a certain range. When the telescopic charging cable 112 is needed for charging, the part of the telescopic charging cable 112 exposed to the outside of the vehicle charger 1 can be pulled to drive the telescopic charging cable 112 to elongate, so as to charge the mobile device. After the charging is completed, the telescopic charging cable 112 automatically retracts to the position before being pulled.

[0052] The arrangement of the telescopic charging cable 112 can easily pull out or retract according to the user's needs, reducing the inconvenience caused by the overlong or too short charging cable.

[0053] It can be understood that the realization mode of stretching and retracting of the telescopic charging wire 112 is not limited, and can be realized by an existing telescopic structure, which is not limited here.

[0054] The telescopic module 11 is rotatably connected with the connecting module 10, and the telescopic module 11 can rotate around the axis relative to the connecting module 10 within a preset angle range.

[0055] Here, the axis is the rotation axis of the telescopic module 11, and the axis can be parallel to the top-bottom direction of the vehicle charger 1, and the top-bottom direction of the vehicle charger 1 can be consistent with the axial direction of the vehicle charger 1.

[0056] It should be noted that the telescopic module 11 can rotate relative to the connecting module 10, that is, the telescopic module 11 and the connecting module 10 have relative rotation, and the telescopic module 11 changes the position relative to the connecting module 10 by rotating. The telescopic module 11 can rotate relative to the connecting module 10 under the action of an external force.

[0057] It should be noted that the preset angle range refers to the angle interval within which the telescopic module 11 can rotate around the axis relative to the connecting module 10.

[0058] It can be understood that the vehicle charger in the related art is limited by the length of the charging wire when used by users at different positions, and is inconvenient to charge. On the other hand, the vehicle charger also needs to be rotated relative to the vehicle around the electrical connection position of the vehicle, which is inconvenient to operate and can also cause poor electrical connection with the vehicle, affecting the user experience.

[0059] The vehicle charger 1 provided in the embodiment of the present application can rotate the telescopic module 11 to make the position of the charging interface of the telescopic charging wire 112 appropriate after the vehicle charger 1 is electrically connected with the vehicle, so as to adapt to the charging demand at different positions. At this time, the electrical connection position of the vehicle charger 1 with the vehicle remains unchanged, reducing the probability of poor electrical connection with the vehicle. Moreover, only the telescopic module 11 needs to be rotated, which is simple and convenient to operate. When the position of the telescopic charging wire 112 is appropriate, the telescopic charging wire 112 can be pulled to obtain an appropriate length, thereby reducing the limitation of the length of the wire and facilitating charging, and increasing the user experience. At the same time, the vehicle charger 1 can be designed to be small in size and will not occupy too much space in the vehicle.

[0060] For example, in the vehicle application scenario, the rotation of the telescopic module 11 relative to the connecting module 10 can meet the charging demand at the driver's seat, the front passenger seat, and the rear seat, and facilitate the user to charge at different positions.

[0061] It can be understood that the preset angle range is set to limit the rotation range of the telescopic module 11 within a preset interval.

[0062] In some embodiments, the preset angle range is 120°-270°, for example, 120°, 135°, 143°, 150°, 162°, 177°, 180°, 200°, 210°, 240°, 250°, 261°, 270°, etc.

[0063] In this embodiment, the setting of the preset angle range can meet the use requirements of different positions while reducing damage or poor contact caused by excessive twisting of internal wires and connecting pieces of the vehicle charger 1, reducing wear of internal wires and connecting pieces, and increasing the reliability and service life of the vehicle charger 1.

[0064] In some embodiments, the preset angle range is 150°-210°, for example, 150°, 155°, 160°, 162°, 170°, 174°, 180°, 182°, 188°, 196°, 203°, 210°, etc.

[0065] In this embodiment, the rotation range of the telescopic module 11 can be more appropriate, so as to further increase the stability of the vehicle charger 1 and have sufficient rotation range to meet the charging requirements of different positions.

[0066] In some embodiments, the rotation position of the telescopic module 11 includes a first position and a second position. In the first position, the rotation angle of the telescopic module 11 relative to the connecting module 10 is 0°, and the preset angle range is the angle range through which the telescopic module 11 rotates from the first position to the second position in the clockwise or counterclockwise direction.

[0067] Here, the first position is the position of the telescopic module 11 before it starts to rotate, and the second position is the extreme position after the telescopic module 11 rotates in the clockwise direction by the preset angle range from the first position.

[0068] It can be understood that in this embodiment, the preset angle range is the angle range through which the telescopic module 11 rotates from the first position to the second position in one direction, or the angle range through which the telescopic module 11 rotates from the second position to the first position in one direction.

[0069] In this embodiment, the setting of the first position and the second position can facilitate the user to return to the position before the telescopic module 11 is driven after rotating the telescopic module 11, thereby increasing the operation reliability.

[0070] In other embodiments, the rotation position of the telescopic module 11 includes a first position, a second position, and a third position. In the first position, the rotation angle of the telescopic module 11 relative to the connecting module 10 is 0° (as shown in FIG. 1A), and the telescopic module 11 can rotate from the first position to the second position in the clockwise direction (as shown in FIG. 1B). Figure 1 Figure 6 ​As shown, the telescopic module 11 can rotate counterclockwise from the first position to the third position (as shown) in the circumferential direction; the preset angle range is the rotation angle range of the telescopic module 11 between the second position and the third position. Figure 7

[0071] That is, in this embodiment, the first position is located between the second position and the third position. Before the telescopic module 11 is rotated, the telescopic module 11 is in the first position, and in the first position, the user can choose to rotate clockwise or counterclockwise in the circumferential direction, that is, the telescopic module 11 can rotate in two directions in the first position, thereby increasing the flexibility of the position adjustment of the telescopic charging wire 112.

[0072] In some embodiments, as shown in Figures 2 to 5 , part of the structure of the bottom wall of the shell 111 protrudes towards the bottom side to form a protruding structure 111c, and part of the structure of the top wall of the connecting module 10 is recessed towards the bottom side to form a ring groove 10b, and the protruding structure 111c is located in the ring groove 10b.

[0073] Specifically, in this embodiment, the docking of the shell 111 and the connecting module 10 is realized through the cooperation of the protruding structure 111c and the ring groove 10b, and the docking of the telescopic module 11 and the connecting module 10 is realized, and the protruding structure 111c and the ring groove 10b can increase the installation stability of the telescopic module 11, and at the same time, when the telescopic module 11 rotates relative to the connecting module 10, the protruding structure 111c can also rotate in the ring groove 10b, thereby increasing the rotation reliability.

[0074] The manner in which the telescopic module 11 rotates relative to the connecting module 10 is not limited.

[0075] In some embodiments, the shell 111 is provided with a rotating structure, and the connecting module 10 is provided with a connecting structure, and the rotating structure and the connecting structure are rotationally connected to realize the rotation of the telescopic module 11 relative to the connecting module 10.

[0076] That is, in this embodiment, the relative rotation is realized by providing the rotating structure on the shell 111 and cooperating with the connecting structure on the connecting module 10, that is, only the entire telescopic module 11 needs to be rotated by the shell 111, which is simple and convenient to operate, and the structure of the vehicle charger 1 can also be simpler.

[0077] The specific structure of the rotating structure and the connecting structure is not limited.

[0078] In some embodiments, as shown in Figure 2 and Figure 5 ​The rotating structure includes a slot rail 111d formed on the bottom wall of the shell 111, and the connecting structure includes a clamping block 101 formed on the top wall of the connecting structure. The clamping block 101 is inserted into the slot rail 111d, and the shell 111 rotates relative to the clamping block 101 through the slot rail 111d. The slot rail 111d has a first slot wall 111e and a second slot wall 111f on opposite sides in the circumferential direction.

[0079] When the telescopic module 11 rotates clockwise relative to the connecting module 10, the rotation is limited in the clockwise direction by the contact between the clamping block 101 and the first slot wall 111e. When the telescopic module 11 rotates counterclockwise relative to the connecting module 10, the rotation is limited in the counterclockwise direction by the contact between the clamping block 101 and the second slot wall 111f.

[0080] Specifically, when the telescopic module 11 rotates clockwise relative to the connecting module 10, the clamping block 101 contacts the first slot wall 111e, forming a physical barrier to limit the continued clockwise rotation of the telescopic module 11, thereby limiting the range of clockwise rotation of the telescopic module 11. When the telescopic module 11 rotates counterclockwise relative to the connecting module 10, the clamping block 101 contacts the second slot wall 111f, forming a physical barrier to limit the continued counterclockwise rotation of the telescopic module 11, thereby limiting the range of counterclockwise rotation of the telescopic module 11.

[0081] In this embodiment, the rotation of the telescopic module 11 relative to the connecting module 10 is achieved by the cooperation of the clamping block 101 and the slot rail 111d. The structure of the clamping block 101 and the slot rail 111d is simple, and they are not easy to disengage when relative rotation occurs, increasing the stability of the rotation. Furthermore, the rotation of the telescopic module 11 in the circumferential direction is limited by the contact between the clamping block 101 and the first slot wall 111e and the second slot wall 111f, so that the rotation of the telescopic module 11 is limited within a reasonable range, reducing the probability of structural damage due to excessive rotation.

[0082] In the embodiment where the telescopic module 11 and the connecting module 10 are connected by the protruding structure 111c and the ring groove 10b, the relative rotation of the clamping block 101 and the slot rail 111d can further increase the stability of the connection and the relative rotation stability of the telescopic module 11 and the connecting module 10.

[0083] The number of telescopic charging lines 112 is not limited and can be one or multiple.

[0084] In some embodiments, the number of telescopic charging lines 112 is multiple, and the charging interfaces of the multiple telescopic charging lines 112 are located at different positions of the vehicle charger 1, and at least two of the charging interfaces are used to realize different charging functions.

[0085] Here, the plurality of retractable charging wires 112 can meet the charging needs of a plurality of mobile devices, and the charging interfaces of the plurality of retractable charging wires 112 are located at different positions of the vehicle charger 1, that is, each retractable charging wire 112 is independent of each other, and the charging interfaces are arranged at different positions of the vehicle charger 1, so as to meet the charging needs of different positions at the same time.

[0086] Here, at least two of the interfaces are used to implement different charging functions, that is, they can charge different types or models of mobile devices.

[0087] For example, one of the interfaces can be a Type-C interface, and the other interface can be a Lightning interface or a Micro-USB interface.

[0088] In this embodiment, the arrangement of the plurality of retractable charging wires 112 and their charging interfaces can meet the charging needs of multiple users and different devices while meeting the charging needs of different positions, increase the adaptability of the vehicle charger 1, and improve the user experience.

[0089] Here, the plurality can be two or more.

[0090] In some embodiments, please refer to Figures 1 to 7 The number of retractable charging wires 112 is at least two, and the at least two retractable charging wires 112 include a first charging wire 1121 and a second charging wire 1123.

[0091] In the initial position, the part of the first charging wire 1121 located outside the opening and the part of the second charging wire 1123 located outside the opening extend towards each other, the first charging wire 1121 is plugged for charging through the first charging interface 1122, the second charging wire 1123 is plugged for charging through the second charging interface 1124, and the first charging interface 1122 and the second charging interface 1124 are arranged towards each other and spaced apart; wherein the initial position is the position of the retractable charging wire 112 when it is not acted upon by an external force.

[0092] It can be understood that the first charging interface 1122 and the second charging interface 1124 can be the same type of interface, that is, they implement the same charging function, or they can be different types of interfaces, that is, they implement different charging functions.

[0093] Here, the first charging interface 1122 and the second charging interface 1124 are arranged towards each other and spaced apart, that is, the first charging interface 1122 and the second charging interface 1124 are arranged substantially face to face and have a gap between them. The initial position refers to the position of the retractable charging wire 112 when it is not pulled out, at which time the part of the retractable charging wire 112 located outside the vehicle charger 1 has the smallest size.

[0094] In this embodiment, the arrangement of the first charging interface 1122 and the second charging interface 1124 can reduce the operation space of the user and facilitate the user to simultaneously perceive the position and direction of the first charging interface 1122 and the second charging interface 1124, and more easily operate in a narrow space. Also, the arrangement can reduce the entanglement and interference between the first charging wire 1121 and the second charging wire 1123, and increase the use reliability of the vehicle charger 1.

[0095] In some embodiments, referring to Figure 1 , the position of the first charging interface 1122 is higher than the position of the second charging interface 1124 in the top-bottom direction of the vehicle charger 1.

[0096] That is, the first charging interface 1122 and the second charging interface 1124 have a height difference, so that the probability of entanglement when the first charging wire 1121 and the second charging wire 1123 are stretched can be further reduced, and the reliability of the vehicle charger 1 can be increased.

[0097] In some embodiments, referring to Figures 1 to 4 , the telescopic module 11 includes a first winding module 113 and a second winding module 114, the first winding module 113 and the second winding module 114 are arranged in the housing 111, and the first winding module 113 is arranged on the top side of the second winding module 114.

[0098] The number of openings is at least two, and the at least two openings include a first opening 111a and a second opening 111b. The first opening 111a is arranged on one side of the housing 111 in a first direction, and the first charging wire 1121 is arranged in the first opening 111a. The second opening 111b is arranged on one side of the housing 111 in a second direction, and the second charging wire 1123 is arranged in the second opening 111b.

[0099] In the top-bottom direction of the vehicle charger 1, at least part of the position of the first opening 111a is higher than the position of the second opening 111b, the first charging interface 1122 extends in the second direction, and the second charging interface 1124 extends toward the first direction; wherein the first direction, the second direction, and the top-bottom direction are perpendicular to each other.

[0100] In this embodiment, the first winding module 113 and the second winding module 114 are arranged in the top-bottom direction, which can reduce the probability of interference and reduce the transverse dimension of the vehicle charger 1. The first charging wire 1121 and the second charging wire 1123 can be independent of each other and do not affect each other, and can be easily pulled out by the user from different directions. The height difference between the first charging interface 1122 and the second charging interface 1124 is realized by the height difference between the first opening 111a and the second opening 111b, which reduces the probability of wire entanglement and has good stability.
