Examples

Referring to fig. 1 to 13, the present embodiment provides a multifunctional data line 1000, where the multifunctional data line 1000 includes: data line body 100, housing 200 and movable components.

The data line body 100 has a USB interface 110 at one end, a plurality of branches 120 at the other end, and a mobile phone interface 130 at an end of the branches 120. The mobile phone interface 130 is flexible in arrangement mode, and can be arranged into the same type of mobile phone interface 130 to meet the requirement of simultaneous use of the same type of mobile phone. Different types of mobile phone interfaces 130 can be arranged on different branches 120 to adapt to different models. In this embodiment, the interface types of the mobile phone interfaces 130 set in different branches 120 are different, so as to improve the adaptability to different models.

The housing 200 has a plurality of cavities 210 spaced along a circumferential direction thereof, and an inner wall of the cavity 210 is provided with guide grooves 211 in an arc shape. The housing 200 further defines a sliding groove 213, and a groove bottom of the sliding groove 213 penetrates the inner cavity 210 to communicate the inner cavity 210 with the outside. The housing 200 further defines an outlet 214 through which the phone interface 130 passes.

The movable assembly includes a slider 300 and a swinging member 400. The swing member 400 has one end hinged to an inner wall of the inner cavity 210 and the other end slidably fitted to the guide groove 211. In this embodiment, the swinging member 400 has a fan shape, and has one end hinged to the side wall of the inner cavity 210 and the other end slidably fitted to the guide groove 211. The center of circle corresponding to the guide slot 211 is located on the rotation axis of the swinging member 400. The end of the swing member 400 far from the hinge point is also an arc-shaped wall, and the radian of the arc-shaped wall is matched with the guide groove 211, so that the swing member 400 can be guaranteed to smoothly swing along the guide groove 211 by taking the hinge point as a rotation base point.

The swing member 400 is provided with first guide wheels 410, the rotation axes of the two groups of first guide wheels 410 are arranged in parallel and are arranged at intervals, and a gap for the wire 120 to pass through is arranged between the two groups of first guide wheels 410.

The inner end of the outlet 214 is provided with the second guide wheels 216, the rotating axes of the two groups of second guide wheels 216 are arranged in parallel and are respectively arranged at two sides of the outlet 214, and a gap for the wire 120 to pass through is arranged between the two groups of second guide wheels 216.

The sliding block 300 is slidably fitted to the sliding groove 213, and the sliding block 300 extends into the inner cavity 210 through the sliding groove 213 to drive the swinging member 400 to slide along the guiding groove 211, so that the first guiding wheel 410 can receive the branch line 120 into the inner cavity 210.

In use, assuming that the phone jack 130 is in a fully extended state (i.e., fully extended from the outlet 214 and located outside the outlet 214), the wire 120 is sequentially assembled in the housing 200 through the outlet 214, the two sets of second guide rollers 216, and the two sets of first guide rollers 410 from the end of the phone jack 130. In this state, the wire outlet 214, the gap between the two second guide wheels 216, and the gap between the two first guide wheels 410 are substantially aligned (not limited to being absolutely aligned, and allowing a certain error), the branch wire 120 is in a straight state, and the handset interface 130 is fully extended. In this use state, the handset interface 130 can be directly connected to a handset. Because the multifunctional data line 1000 is provided with the plurality of mobile phone interfaces 130 arranged along the circumferential direction of the shell 200, the mobile phones can be placed along the circumferential direction of the shell 200 and connected with the mobile phone interfaces 130, the arrangement mode greatly improves the collection quantity of the multifunctional data line 1000 which can be connected simultaneously, and the mobile phones are not stacked and collided, so that the multifunctional data line is more friendly to the mobile phones, is more convenient to use and is convenient to place the mobile phones.

When the mobile phone interface 130 needs to be retracted into the housing 200, the sliding block 300 is pushed to the other end of the sliding slot 213, and the sliding block 300 can push the swinging member 400 to swing along the guiding slot 211, so as to drive the first guiding wheel 410 to move. As the swing member 400 swings, the first guide wheel 410 deflects relative to the second guide wheel 216 and the wire outlet 214, the two groups of first guide wheels 410 deviate from the linear position formed by the wire outlet 214 and the two groups of second guide wheels 216, at this time, the wire 120 is pulled by the two groups of first guide wheels 410 to be pulled from the wire outlet 214 to the inner cavity 210, after the sliding block 300 slides to the other end of the sliding groove 213, the swing member 400 hits a swing stop, the wire 120 is fully drawn into the inner cavity 210 by the two groups of first guide wheels 410, and the handset interface 130 connected to the wire 120 is drawn into the wire outlet 214. At this point, the housing of the handset interface 130 is completed.

Through the above operations, the extension line 120 and the mobile phone interface 130 can be conveniently and quickly stored. During the storage process, the two sets of first guide wheels 410 pull the wire 120, and apply force by contacting the wheel surfaces with the wire 120. The two sets of second guide wheels 216 serve as a guide for guiding the wire 120 from the outlet 214 into the cavity 210. The wheel surfaces of the first guide wheel 410 and the second guide wheel 216 are in contact with the distributing line 120, on one hand, the wheel surfaces are used as supports and supports for bending the distributing line 120, the wall surfaces are excessively bent and damaged in the process of accommodating the distributing line 120, and the smoothness of bending the distributing line 120 are greatly improved. On the other hand, the friction and the resistance of the wire separation 120 during the movement process can be greatly reduced by the first guide wheel 410 and the second guide wheel 216, the abrasion of the wire separation 120 is further reduced, and the service life of the wire separation 120 is prolonged.

If the mobile phone interface 130 needs to be extended again, only the sliding block 300 needs to be slid reversely to reset the sliding block 300, the swinging piece 400 is driven by the sliding block 300 to swing reversely to reset, and the two groups of first guide wheels 410 also move back to the initial position along with the swinging piece 400. During the return of the first guide wheels 410, the first guide wheels 410 have a "pushing" action on the wire 120, causing it to move towards the second guide wheel 216, so that it can re-extend through the outlet 214. The wheel surfaces of the first guide wheel 410 and the second guide wheel 216 are in contact with the wire-dividing line 120, and the surface of the wire-dividing line 120 can be prevented from being scratched by the first guide wheel 410 in the process of pushing the wire-dividing line 120. The second guide wheel 216 can smoothly guide the separated wire 120 to enter the outlet 214, so as to prevent the separated wire 120 from directly contacting with the end wall of the outlet 214 to cause abrasion, and both the separated wire 120 and the outlet greatly reduce the friction resistance in the movement process of the separated wire 120, so that the movement of the separated wire 120 is smoother, and the adjustment is easier.

Generally, the multifunctional data line 1000 is convenient to carry, can play a good protective role to the data line body 100, prevent that the wire winding from knotting, reduce the damage that the wire rod received, and it still has abundant cell phone interface 130 simultaneously, can realize the multiple port connection, and the function is abundanter, and the operation is also simpler.

Further, in order to facilitate the transmission of the driving of the slider 300, one end of the swing member 400 adjacent to the guide groove 211 has a first rack 420 provided along the extending direction of the guide groove 211. The movable assembly further includes a first driving gear 500 and a second driving gear 600, each of the first driving gear 500 and the second driving gear 600 being rotatably connected to an inner wall of the inner cavity 210.

The sliding groove 213 is connected with a second rack 310 disposed along a length direction thereof, and the second driving gear 600 is engaged with the second rack 310. The first driving gear 500 is coaxially connected with a first synchronous wheel 510, the second driving gear 600 is coaxially connected with a second synchronous wheel 610, and the first synchronous wheel 510 and the second synchronous wheel 610 are in transmission connection through a synchronous belt 700.

In this embodiment, both ends of the rotation shaft of the first driving gear 500 are fitted to both side inner walls of the inner cavity 210, and the rotation shaft of the first driving gear 500 is located at a side of the guide groove 211 away from the swinging member 400. And the rotation shaft of the second driving gear 600 is installed at an inner wall of a side away from the swing member 400 (i.e., the second driving gear 600 is installed at a side wall surface opposite to the wall surface to which the swing member 400 is hinged) and is disposed near the sliding groove 213.

It should be noted that the synchronous belt 700 transmission may be replaced by a gear transmission, and is not limited thereto.

In the process of sliding the slider 300, the second rack gear 310 drives the second driving gear 600, and the second driving gear 600 drives the first synchronizing wheel 510 via the second synchronizing wheel 610, so that the first driving gear 500 drives the swinging member 400 to slide (swing) along the guide groove 211 via the first rack gear 420.

Taking the view of fig. 9 as an example, the swinging member 400 and the guide groove 211 are both located on the inner wall of the bottom side, both ends of the rotating shaft of the first driving gear 500 are respectively mounted on the inner wall of the bottom side and the inner wall of the top side, and the rotating shaft is located on the side of the guide groove 211 far away from the swinging member 400. The first driving gear 500 is positioned above the guide groove 211, and the first rack gear 420 is also positioned on the upper surface of the swing member 400 and engaged with the first driving gear 500. The first sync wheel 510 is positioned above the first driving gear 500.
