Mobile device with detachable power storage device

Abstract

A mobile device with a releasable power storage device is provided. The mobile device comprises a cabinet, a power storage device detachably engaged with the cabinet, a latch disposed on the cabinet adjacent to a side wall thereof and capable of moving along the side, and an engaging portion engaged with the latch. The power storage device comprises a stopping portion and a guiding portion. The stopping portion and the engaging portion are alternatively disposed on one side of the body. When an external force is exerted on the engaging portion, the latch is moved to push the guiding portion of the power storage so as to eject the power storage device from the cabinet.

1 . A mobile device, comprising: 
 a cabinet;    a power storage device detachably engaged with the cabinet, comprising a stopping portion and a guiding portion alternately disposed on one side wall thereof; and    a latch disposed on the cabinet, adjacent to the side of the body and capable of moving along the side wall; and    an engaging portion engaged with the latch.    
   
   
       2 . The mobile device as claimed in  claim 1 , wherein the guiding portion has an inclined surface which has a predetermined angle with respect to the moving direction of the latch.  
   
   
       3 . The mobile device as claimed in  claim 2 , wherein the predetermined angle is greater than 0° and less than or equal to 90°.  
   
   
       4 . The mobile device as claimed in  claim 2 , wherein the stopping portion is substantially L-shaped, and has a first lateral surface parallel to the moving direction of the latch and a second lateral surface connected to the first lateral surface.  
   
   
       5 . The mobile device as claimed in  claim 4 , wherein the latch comprises a post and a hole, the cabinet comprises an opening, and the engaging portion comprises a protrusion, and when the latch and the engaging portion engages the cabinet, the post is inserted into the opening and the protrusion engages the hole.  
   
   
       6 . The mobile device as claimed in  claim 5 , wherein when the power storage device is placed in the cabinet, the post engages the corner between the first lateral surface and the second lateral surface, and when an external force is exerted on the protrusion, the protrusion moves the latch so as to move the post toward the guiding portion, whereby the post pushes the guiding portion to eject the power storage device from the cabinet.  
   
   
       7 . The mobile device as claimed in  claim 1 , wherein the cabinet comprises at least one cavity, and the power storage device comprises at least one tab engaging with the cavity.  
   
   
       8 . The mobile device as claimed in  claim 1 , wherein the cabinet comprises a depression in which the power storage device is accommodated.  
   
   
       9 . The mobile device as claimed in  claim 1 , wherein the cabinet comprises a channel in which the latch and the engaging portion are movably disposed.  
   
   
       10 . The mobile device as claimed in  claim 1  further comprising an elastic element having a first link portion connected to the latch and a second link portion connected to the cabinet.  
   
   
       11 . The mobile device as claimed in  claim 10 , wherein the elastic element is an expansion spring.  
   
   
       12 . The mobile device as claimed in  claim 1 , wherein the latch is made of durable plastic.  
   
   
       13 . The mobile device as claimed in  claim 1 , wherein the power storage device is a battery.
