[0073] In the embodiment, the number of the first mounting column 190 is three, which can meet the installation need and determine a circle through three points, and the rotation center can be determined.

[0074] In some specific embodiments of the utility model, the first mounting column 190 can be one, the end surface of the first mounting column 190 is connected with the first mounting ring 170, and the inner side of the first mounting column 190 is provided with a wire passage.

[0075] In some specific embodiments of the utility model, the outer side of the first mounting ring 170 can be matched with the inner surface of the first shell 150 to form a hole shaft, meeting the need of center positioning during rotation.

[0076] In some specific embodiments of the utility model, the rotating limiting structure can be arranged between the charging connecting piece 130 and the first mounting arm 110, the rotating limiting structure includes a limiting convex portion 200 and an arc-shaped limiting slot 210 accommodating the limiting convex portion 200, when the charging connecting piece 130 rotates, the limiting convex portion 200 moves along the arc-shaped limiting slot 210, and the two ends of the arc-shaped limiting slot 210 can abut against the limiting convex portion 200 to limit the rotation angle of the charging connecting piece 130.

[0079] Meanwhile, the rotation limiting structure is located in the first shell 150, does not affect the appearance, and is not easy to jam.

[0080] In some specific embodiments of the utility model, the first mounting part 180 can be provided with an arc-shaped limiting groove 210, and the first shell 150 or the entity part forming the first opening 160 is provided with a limiting protrusion 200, which can also meet the rotation limiting requirement, meanwhile, the first mounting ring 170 is relatively complete, can have higher strength, so that the charging connecting piece 130 and the first mounting arm 110 are connected firmly, and the charging connecting piece 130 is not easy to fall off due to stress.

[0081] In some specific embodiments of the utility model, the arc-shaped limiting groove 210 can have an inner arc surface or an outer arc surface concentrically arranged with the rotation center of the charging connecting piece 130, so as to avoid affecting the rotation of the charging connecting piece 130, and at the same time, the shape limitation of the arc-shaped limiting groove 210 is reduced.

[0082] In some specific embodiments of the utility model, the limiting protrusion 200 can be an arc-shaped plate, so as to improve the strength of the limiting protrusion 200, reduce the risk of fracture, and at the same time, not affect the normal rotation of the charging connecting piece 130.

[0083] In the embodiment, the arc-shaped limiting groove 210 and the limiting protrusion are arranged between the charging connecting piece 130 and the first mounting arm 110, that is, the arc-shaped limiting groove 210 is located in the charging connecting piece 130, and the limiting protrusion is located in the first mounting arm 110, or the arc-shaped limiting groove 210 is located in the first mounting arm 110, and the limiting protrusion is located in the charging connecting piece 130.

[0085] It is easy to understand that, by setting the positioning concave part 220 and the positioning convex part, the embodiment also makes different positioning convex parts be clamped into different positioning concave parts 220 when the charging connecting piece 130 rotates, has rotation resistance, avoids the charging connecting piece 130 from rotating at will, enables the charging connecting piece 130 to rotate gradually, keeps a reasonable angle, makes sound during rotation, and facilitates a user to determine whether rotation is in place.

[0086] In some specific embodiments of the utility model, the positioning convex part can have one, and the positioning concave part 220 can have multiple; the positioning concave part 220 can also have one, and the positioning convex part can have multiple; or the positioning convex part and the positioning concave part 220 can both have multiple, and are arranged in a ring shape with the rotation center of the charging connecting piece 130 as the center, so as to ensure that the positioning convex part can be clamped into the positioning concave part 220.

[0087] In some specific embodiments of the utility model, a spring can be arranged between the charging connecting piece 130 and the first mounting arm 110, so that the positioning convex part is elastically clamped into the positioning concave part 220, and abrasion is reduced.

[0088] In the embodiment, the positioning concave part 220 is displayed between the power connecting piece 140 and the second mounting arm 120, for easy understanding.

[0090] It is easy to understand that, by making the axis of the winding shaft be parallel to the rotation axis of the charging connecting piece 130, the charging connecting piece 130 can be automatically rotated when the charging cord is pulled, the charging cord is conveniently pulled out, and use is facilitated.

[0091] In some specific embodiments of the utility model, the number of charging cords can be two, and the pulling directions of the two charging cords are oppositely arranged.

[0092] It is easy to understand that, by arranging two charging cords, the embodiment can increase the charging port, facilitate charging of two mobile phones or electronic devices, and by oppositely arranging the pulling directions of the two charging cords, the embodiment also facilitates pulling out of the charging cords in two opposite directions, and simultaneously meets the charging needs of the driver seat and the copilot seat.

[0093] Meanwhile, since the mounting support 100 of the embodiment has the first mounting arm 110 and the second mounting arm 120, the space surrounded by the first mounting arm 110 and the second mounting arm 120 is large, and the large charging connecting piece 130 is conveniently arranged, so that the charging connecting piece 130 can be provided with two or even more charging wires, meeting the charging needs of multiple electronic devices and being more in line with user needs.

[0095] The conductive connecting end 230 is exposed outside the first shell 150, and the conductive connecting end 230 can abut against the outer surface of the first shell 150.

[0096] The conductive connecting end 230 can abut against the first shell 150 and the second mounting arm 120 at the same time to limit the rotation of the charging connecting piece 130, which means that when the charging connecting piece 130 rotates, the gap between the first shell 150 and the second mounting arm 120 is smaller than the thickness of the conductive connecting end 230 or the thickness of a certain step, so that the conductive connecting end 230 cannot pass through the gap between the first shell 150 and the second mounting arm 120.

[0097] It is easy to understand that the embodiment also limits the rotation of the charging connecting piece 130 through the conductive connecting end 230 of the charging wire, so that the rotation angle of the charging connecting piece 130 is limited, avoiding the damage of the internal wire due to twisting and avoiding affecting the use.

[0098] At the same time, it is also beneficial to reduce the height of the charging connecting piece 130, or in other words, to reduce the height of the vehicle-mounted charger and to reduce the occupied space, facilitating application.

[0099] For the mounting support 100, the mounting support 100 can include an L-shaped shell 240 and an L-shaped inner cover 250, the L-shaped shell 240 and the L-shaped inner cover 250 cooperate to form the first mounting arm 110 and the second mounting arm 120, and the space between the L-shaped shell 240 and the L-shaped inner cover 250 is used to form a wire arrangement channel.
