Compared with the prior art, the automatic telescopic charging interface structure at least has the following technical effects:

the automatic flexible interface structure that charges that this application embodiment provided can removecasing 100 relatively under the exogenic action through setting upflexible interface module 200 to makeflexible interface module 200 stretch outcasing 100 andretraction casing 100 according to user's user demand, when need not usingflexible interface module 200,flexible interface module 200 can retract the inside ofcasing 100, in order to realizeflexible interface module 200, practices thrift occupation space. When thetelescopic interface assembly 200 is required to be used, thetelescopic interface assembly 200 can be extended out of thehousing 100, so that thetelescopic interface assembly 200 can be directly connected with an external power supply device.

This application sets up theflexible interface module 200 that can stretch out and draw back incasing 100 inside, and the socket flushes in the interface module ofcasing 100 lateral surface and compares among the prior art, and theflexible interface module 200 of this application stretches out behindcasing 100, and at least some protrusion in casing 100 offlexible interface module 200 to can be directly connected with outside power supply unit, need not other connecting wires of reconnection in addition (like the USB line), it is more convenient to make the operation of charging. Through the setting ofelastic component 500, makeflexible interface module 200 after receiving the initial external force that the user applyed, can realize stretching out and retracting intocasing 100 under the thrust effect ofelastic component 500, realize the automatic flexible offlexible interface module 200, play the effect of saving strength, and make the flexible operation offlexible interface module 200 more convenient.

In one embodiment, theelastic member 500 is a torsion spring, the torsion spring includes atorsion spring body 511, afirst force arm 512 and asecond force arm 513, thefirst force arm 512 and thesecond force arm 513 are respectively connected to two ends of thetorsion spring body 511, thefirst force arm 512 is connected to thehousing 100, thesecond force arm 513 is connected to thetelescopic interface component 200, thesecond force arm 513 is driven by thetelescopic interface component 200 to move relative to thefirst force arm 512, and thetorsion spring body 511 can be twisted and moved when thesecond force arm 513 moves.

When thetelescopic interface assembly 200 extends out of thehousing 100, thesecond force arm 513 applies a pushing force to thetelescopic interface assembly 200 in a direction extending out of thehousing 100; when thetelescopic interface assembly 200 is retracted into thehousing 100, thesecond force arm 513 applies a pushing force to thetelescopic interface assembly 200 in the direction of retracting into thehousing 100.

Specifically, in this embodiment, thesecond force arm 513 on thetorsion spring body 511 is driven by the movement of thetelescopic interface component 200 to move together with thetelescopic interface component 200 relative to thehousing 100, and thefirst force arm 512 on thetorsion spring body 511 is connected to thehousing 100, so that the position of one end of thefirst force arm 512 in thehousing 100 is not changed, so that in the moving process of thetelescopic interface component 200, the two force arms of thetorsion spring body 511 move relatively, so that thetorsion spring body 511 can deform while driving thetelescopic interface component 200 by an external force to generate torsion and movement, when the deformation of thetorsion spring body 511 reaches a critical point, thetorsion spring body 511 applies energy to thetelescopic interface component 200 through thefirst force arm 512 in a direction opposite to the direction before the deformation critical point of thetorsion spring body 511 is reached, so that thetelescopic interface component 200 respectively receives two thrusts in different directions before and after the deformation critical point of thetorsion spring body 511, thereby, thetelescopic interface assembly 200 can receive two thrusts in different directions during the process of extending out and retracting into theshell 100.

It can be understood that, in the two processes of extending and retracting thetelescopic interface assembly 200 into and out of thehousing 100 respectively under the action of external force, thetorsion spring body 511 is torsionally deformed, and the processes of torsional deformation and thrust generation are as follows:

in the process that thetelescopic interface assembly 200 extends out of thehousing 100 from the inside of thehousing 100, thetelescopic interface assembly 200 moves under the acting force applied by the user, thetorsion spring body 511 is in an initial state (a torsional state as shown in fig. 3), thesecond force arm 513 moves along with thetelescopic interface assembly 200, and before the torsional deformation of thetorsion spring body 511 reaches a critical point, thetorsion spring body 511 applies a pushing force (resists deformation) towards the inside of thehousing 100 to thetelescopic interface assembly 200 through thesecond force arm 513, so as to prevent thetelescopic interface assembly 200 from being accidentally touched and ejected; at this time, thetelescopic interface assembly 200 continues to move in the direction of extending out of thehousing 100, and after the torsional deformation of thetorsion spring body 511 reaches the critical point (as shown in fig. 4), thetorsion spring body 511 will apply a pushing force to thetelescopic interface assembly 200 through thesecond arm 513, until thetorsion spring body 511 is fully deformed into the unfolded state (as shown in fig. 5).

In the process of retracting the retractable interface assembly 200 into the housing 100, the retractable interface assembly 200 moves under the action of the force applied by the user, the second force arm 513 moves along with the retractable interface assembly 200, so that the torsion spring body 511 starts to be torsionally deformed from the unfolded state (as shown in fig. 5) to the torsional state, before the torsional deformation of the torsion spring body 511 reaches the critical point, the torsion spring body 511 applies a pushing force (resists deformation) towards the outside of the housing 100 to the retractable interface assembly 200 through the second force arm 513, thereby preventing the retractable interface assembly 200 from being easily retracted into the housing 100 and affecting the insertion with the external power supply equipment, at this time, one end of the second force arm 513, which is far away from the torsion spring body 511, continues to move towards the direction of retracting into the housing 100, and when the deformation of the torsion spring body 511 reaches the critical point (as shown in fig. 4), the torsion spring body 511 applies a pushing force towards the inside of the housing 100 to the retractable interface assembly 200 through the second force arm 513, until the torsion spring body 511 returns to the twisted state (as shown in fig. 3).

In one embodiment, the free angle of the torsion spring is less than 180 °. In this embodiment, when thetelescopic interface assembly 200 is retracted into thehousing 100, thesecond force arm 513 is moved to a position crossing thefirst force arm 512 by an external force (as shown in fig. 3); when thetelescopic interface assembly 200 is extended out of thehousing 100, thesecond force arm 513 is released from crossing thefirst force arm 512 by an external force (as shown in fig. 4 and 5).

It will be appreciated that thefirst force arm 512 and thesecond force arm 513 are angled less than 180 ° when the torsion spring is unloaded. When thetorsion spring body 511 is in a torsional state (as shown in fig. 3), thesecond force arm 513 and thefirst force arm 512 are in an intercrossed state; when thetorsion spring body 511 is in the expanded state (as shown in fig. 4 and 5), thesecond force arm 513 and thefirst force arm 512 are released from the crossed state.
