Telescopic earphone box: example one

As shown in fig. 1 to 14, which are schematic structural views illustrating a first embodiment of a retractable earphone box according to the present invention, a wireless earphone matched with the retractable earphone box can be stored in the retractable earphone box by using the retractable earphone box. Specifically, the retractable earphone box includes a first housing 10, a second housing 20, a functional structure 30 and a related structure, which form a core component module of the retractable earphone box. During assembly, the first housing 10 has a through space 11 (as shown in fig. 6), the second housing 20 is disposed in the through space 11, the first housing 10 has a first working position (not shown) and a second working position (not shown) with respect to the second housing 20, and the first housing 10 is relatively slidable between the first working position and the second working position with respect to the second housing 20. The second casing 20 is provided with an accommodating space 21, the accommodating space 21 is one of the main assembling spaces, the functional structure 30 is installed in the accommodating space 21, and an earphone placing groove 31 for placing the wireless earphone 100 is formed on the functional structure 30; the other main assembly space is the space between the inner wall of the first housing 10 and the outer wall of the second housing 20, and the associated structure is disposed between the first housing 10 and the second housing 20, and the associated structure keeps the first housing 10 in the first working position or in the second working position relative to the second housing 20. In this embodiment, the first casing 10 is located at the first working position relative to the second casing 20, that is, the first casing 10 is in an extended state relative to the second casing 20; the first casing 10 is located at the second working position relative to the second casing 20, that is, the first casing 10 is in the retracted state relative to the second casing 20, and at this time, the first casing 10 completely surrounds the second casing 20, and the working position state will be described below.

When the telescopic earphone box is used with the wireless earphone 100, the wireless earphone 100 is placed in the earphone placing groove 31 for storage. When the wireless headset 100 is stored in the headset accommodating slot 31 (at this time, a part of the ear-in end of the wireless headset 100 protrudes out of the headset accommodating slot 31, so that a user can conveniently grab the wireless headset 100 and take it out of the headset accommodating slot 31), the first housing 10 slides relative to the second housing 20 and the linkage structure keeps the first housing 10 at the first working position, and the protruding part of the first housing 10 relative to the second housing 20 surrounds and protects the protruding part of the wireless headset 100 from the headset accommodating slot 31, so that the wireless headset 100 is prevented from being interfered by external force and being separated from the headset accommodating slot 31 or damaged by collision. When the wireless headset 100 is taken out of the headset placing slot 31 for use, the first housing 10 slides relative to the second housing 20, and the linkage structure keeps the first housing 10 located at the second working position, the first housing 10 retracts relative to the second housing 20, the first housing 10 completely surrounds the second housing 20, that is, the first housing 10 and the second housing 20 overlap, and at this time, the size of the occupied space required by the retractable headset box is about half of the size of the occupied space required when the first housing 10 is located at the first working position relative to the second housing 20. Therefore, under the two situations of storing the wireless earphone 100 and not storing the wireless earphone 100, the relative working position between the first shell 10 and the second shell 20 can be changed, so that the size of the occupied space of the telescopic earphone box is changed, and the design concept of small volume is conformed.

As shown in fig. 8, 13 and 14, the related structure includes a first torsion spring 41, the first torsion spring 41 is compressively installed with a preload between the first housing 10 and the second housing 20, and the first torsion spring 41 provides an elastic force between the first housing 10 and the second housing 20. When the first torsion spring 41 is assembled, the first torsion spring 41 has a first connection end 411 and a second connection end 412, the first connection end 411 is rotatably connected to an inner wall of the first housing 10, the second connection end 412 is rotatably connected to a connection post on an outer wall of the second housing 20, and a connection position of the second connection end 412 on the outer wall of the second housing 20 is approximately in the middle between the first working position and the second working position. Therefore, when the first housing 10 is located at the first working position relative to the second housing 20, the first connection end 411 of the first torsion spring 41 gives the first housing 10 a horizontal component and a vertical upward component (up and down directions when the retractable earphone box is being expanded), wherein the vertical upward component keeps the first housing 10 at the first working position relative to the second housing 20. When the first housing 10 slides relative to the second housing 20 from the first working position to the second working position, the first torsion spring 41 also rotates with the second connection end 412 as a rotation center, and when the first connection end 411 and the second connection end 412 are located at the same horizontal height, at this time, the vertical upward component of the first connection end 411 to the first housing 10 is zero, the first housing 10 continues to slide, the first connection end 411 generates a vertical downward component to the first housing 10, the vertical downward component urges the first housing 10 to continue to slide to the second working position, and after the first housing 10 reaches the second working position, the vertical downward component enables the first housing 10 to remain at the second working position relative to the second housing 20.

As shown in fig. 2, 4 and 8, the related structure further includes a connection push button 42. As shown in fig. 5, the first housing 10 is provided with a transverse strip-shaped hole 12. As shown in fig. 8 to 10, the second housing 20 is provided with a longitudinal sliding groove 22 and a locking notch 23, the longitudinal sliding groove 22 is communicated with the locking notch 23, and in this embodiment, the locking notch 23 corresponds to the first working position. When assembling, the connecting pushing button 42 passes through the transverse bar-shaped hole 12 and the longitudinal sliding groove 22 in sequence, the connecting pushing button 42 connects the first casing 10 and the second casing 20, the first connecting end 411 is rotatably connected to the connecting pushing button 42, the connecting pushing button 42 can slide along the longitudinal sliding groove 22, the connecting pushing button 42 drives the first casing 10 to slide between the first working position and the second working position relative to the second casing 20, when the transverse bar-shaped hole 12 slides to correspond to the locking notch 23 (i.e. the first casing 10 slides to the first working position relative to the second casing 20), the vertical upward component force applied to the first casing 10 by the first torsion spring 41 keeps the first casing 10 at the first working position relative to the second casing 20, and under the action of the horizontal component force applied by the first torsion spring 41, the connecting pushing button 42 can slide into the locking notch 23 to lock the relative position of the first casing 10 and the second casing 20, at this time, the first housing 10 can be kept at the first working position (when the locking notch 23 corresponds to the second working position, the horizontal component force applied to the first housing 10 by the first torsion spring 41 makes the connecting push button 42 slide into the locking notch 23 to keep the first housing 10 at the second working position).

As shown in fig. 13 and 14, the related structure further includes a second torsion spring 43, the second torsion spring 43 being disposed at an opposite side of the first torsion spring 41, the second torsion spring 43 being compressively mounted between the first and

second housings

10 and 20 with a preload, like the first torsion spring 41. Specifically, the second torsion spring 43 has a third connection end 431 and a fourth connection end 432, the third connection end 431 is rotatably connected to the inner wall of the first housing 10, the fourth connection end 432 is rotatably connected to one connection post on the outer wall of the second housing 20, and the connection position of the fourth connection end 432 on the outer wall of the second housing 20 is located approximately in the middle between the first working position and the second working position. The second torsion spring 43 and the first torsion spring 41 together exert an elastic force between the first housing 10 and the second housing 20, and specifically, when the first housing 10 is located at the first working position relative to the second housing 20, the third connecting end 431 of the second torsion spring 43 gives the first housing 10 a horizontal component (in the present embodiment, the horizontal component applied by the second torsion spring 43 is opposite to the horizontal component applied by the first torsion spring 41) and a vertical upward component (up and down directions when the retractable earphone box is being unfolded), wherein the vertical upward component keeps the first housing 10 at the first working position relative to the second housing 20. When the first housing 10 slides relative to the second housing 20 from the first working position to the second working position, the second torsion spring 43 also rotates with the fourth connecting end 432 as a rotation center, and when the third connecting end 431 and the fourth connecting end 432 are located at the same horizontal height, at this time, the vertical upward component of the third connecting end 431 on the first housing 10 is zero, the first housing 10 continues to slide, the third connecting end 431 generates a vertical downward component on the first housing 10, the vertical downward component on one hand drives the first housing 10 to continue to slide to the second working position, and after the first housing 10 reaches the second working position, the vertical downward component enables the first housing 10 to remain at the second working position relative to the second housing 20. Thus, the first torsion spring 41 and the second torsion spring 43 act between the first casing 10 and the second casing 20 at the same time, and the first torsion spring 41 and the second torsion spring 43 are restricted with each other, so that the sliding process of the first casing 10 relative to the second casing 20 can be balanced and stably slid.

Further, the second housing 20 is formed with a fitting longitudinal sliding groove 221 corresponding to the pin hole 14, and the latch 46 is inserted through the pin hole 14 and the fitting longitudinal sliding groove 221 in this order, so that the latch 46 and the connection push button 42 together connect the first housing 10 and the second housing 20. The latch 46 is able to slide along the mating longitudinal slide groove 221.

In order to make the sliding between the first casing 10 and the second casing 20 smoother and keep the relative sliding direction stable, as shown in fig. 7, a protrusion 13 is disposed on the inner wall of the first casing 10, and as shown in fig. 8 to 10, a guide chute 24 is disposed on the outer wall of the second casing 20. After assembly, the projection 13 extends into the guide runner 24, and the projection 13 slides along the guide runner 24.
