Earphone charging case

Abstract

An earphone charging case includes a shell assembly and a locking assembly. The upper cover of the shell assembly is rotatably connected to the lower shell. The locking assembly includes an elastic support rod, a locking rod, and a transmission mechanism. The locking rod is slidably connected to the lower shell along a first direction, with a portion of the locking rod extending into the lower shell. The elastic support rod is angled to the locking rod and connected to the inner wall of the upper cover. The elastic end of the elastic support rod elastically abuts against the side wall of the locking rod. A locking groove is provided on the side of the locking rod near the elastic support rod, and the inner wall of the locking groove has an inclined guide surface. The transmission mechanism is located inside the lower shell and is driven and connected to the locking rod. The transmission mechanism is connected to a knob, which is rotatably connected to the outer wall of the lower shell. The transmission mechanism is configured to drive the locking rod to move along the first direction when the knob is rotated. When the elastic support rod elastically supports the locking groove, the locking rod is located in the locking position.

Claims

1.

The locking rod is slidably connected to the bottom shell along a first direction, with a portion of the locking rod extending into the bottom shell. The elastic support rod is angled to the locking rod and connected to the inner wall of the top cover. The elastic end of the elastic support rod elastically abuts against the side wall of the locking rod. A locking groove is provided on the side of the locking rod near the elastic support rod, and the inner wall of the locking groove has an inclined guide surface. The transmission mechanism is disposed within the bottom shell and is drivenly connected to the locking rod. The transmission mechanism is connected to a knob, which is rotatably connected to the outer wall of the bottom shell. The transmission mechanism is configured to drive the locking rod to move along the first direction when the knob is rotated. When the elastic support rod elastically supports the locking groove, the locking rod is in a locked position.

2. The earphone charging case as described in claim 1, wherein, The transmission mechanism also includes a driving wheel, a driven wheel, and a connecting rod. The knob is provided with a drive rod that extends into the bottom shell and is connected to the driving wheel. The driven wheel is rotatably connected to the bottom shell and is engaged with the driving wheel. The first end of the connecting rod is rotatably connected to the side wall of the driven wheel, and the rotatable connection position is offset from the rotation center of the driven wheel. The second end of the connecting rod is connected to the locking rod.

3. The earphone charging case as described in claim 2, wherein, The locking rod has a guide portion at one end near the driving rod, and the guide portion has an elongated hole extending in a second direction. The second end of the connecting rod is slidably connected to the elongated hole.

4. The earphone charging case as described in claim 1, wherein, A guide block is installed on the inner wall of the bottom shell. The guide block is provided with a guide hole extending along the first direction, and the locking rod is slidably connected to the guide hole.

5. The earphone charging case as described in claim 4, wherein, The locking assembly also includes a first elastic element. The side wall of the locking rod is provided with an annular flange. The first elastic element is sleeved on the locking rod, with one end abutting against the annular flange and the other end abutting against the guide block.

6. The earphone charging case as claimed in claim 1, wherein, The knob includes an initial position, and when the knob is rotated to the initial position, the locking lever is located in the locking position; the earphone charging case also includes a second elastic member configured to drive the knob to the initial position.

7. The earphone charging case as claimed in claim 1, wherein, The top cover is hinged to the bottom shell via a spring hinge, which can drive the top cover to rotate to the open position.

8. The earphone charging case as claimed in any one of claims 1 to 7, wherein, The part where the top cover and the bottom shell are rotatably connected is located on the same side of the earphone charging case as the locking assembly; or, the part where the top cover and the bottom shell are rotatably connected is located on opposite sides of the earphone charging case as the locking assembly.

9. The earphone charging case as claimed in any one of claims 1 to 7, wherein, The elastic support rod includes a support column, a third elastic element and an abutment column. The support column is connected to the upper cover. A connecting groove is provided at one end of the support column near the locking rod. The third elastic element is embedded in the connecting groove, with one end connected to the bottom of the connecting groove and the other end connected to the abutment column. The abutment column is partially slidably connected to the connecting groove.

10. The earphone charging case as claimed in claim 9, wherein, The inner wall of the locking groove is a spherical concave surface, and the end of the abutment post near the locking groove is a spherical convex surface.
