BACKGROUND

1. Field of the Invention

The present disclosure relates to a battery assembling mechanism for an electronic device.

2. Description of Related Art

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are widely used. When a battery is installed in the portable electronic device, the battery is generally shielded and fixed in place by a battery assembling mechanism.

A commonly used battery assembling mechanism includes a cover and a housing. The cover includes a pin at on one end and a protrusion at an opposite end. The housing defines a receiving hole and a holding aperture. The protrusion can be received in the holding aperture, and the cover is impelled towards the housing until the pin is received into the receiving hole. As such, the cover securely engages the housing as the protrusion seated in the holding aperture. However, the cover usually needs to be separated from the housing for removing the battery. The separated cover may easily become lost.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION OF THE EMBODIMENT

FIG. 1shows a battery assembling mechanism of electronic device100. The battery assembling mechanism100includes a housing10, a sliding assembly20, a circuit board30, a connecting terminal40, a cover50and a seal strip60.

FIG. 2further shows the housing10is a frame including a bottom wall12, a first sidewall14, and a second sidewall16. The first sidewall14and the second sidewall16are formed at opposite sides of the bottom wall12. The bottom wall12has a receiving frame121to receive a battery200. The receiving frame121includes two frame walls122symmetrically arranged on the bottom wall12. The frame walls122cooperatively define a receiving chamber123. The receiving chamber123has a first opening1231facing the first sidewall14and a second opening1232facing the second sidewall16. The bottom wall12further has an assembling wall124and two connecting walls125. The assembling wall124is formed at the side of the first opening1231, parallelly abutting the first sidewall14. The assembling wall124has two poles1242protruding from the top surface. The poles1242are for assembly with the sliding assembly20. The two connecting walls125are located at two sides of the second opening1232corresponding to and perpendicular with the second sidewall16. The two connecting walls125and the second sidewall16cooperatively define an accommodating chamber1252to accommodate the connecting terminal40.

The first sidewall14defines a matching groove142exposed at the outer surface. The matching groove142corresponds to the first opening1231and is longer than the first opening1231. The matching groove142defines an assembling hole144and an adjacent fixing aperture148through its bottom wall. The assembling hole144is aligned with the first opening1231. An engaging slot146is defined through the assembling wall124. The engaging slot146communicates with a side of the assembling hole144. The engaging slot146has a guiding slot1462defined through its sidewall. The guiding slot1462extends along the assembling wall124and is used to receive the sliding assembly20. The first sidewall14has a protruding bar149protruding inside the housing10. The protruding bar149is located adjacent to the first opening1231and latches the battery200.

The sliding assembly20includes a holding member22and a sliding unit24. The holding member22includes a first plate portion222and a second plate portion224. The second plate portion224is perpendicular to the first plate portion222. The first plate portion222defines two fixing holes2222to receive the poles1242of the assembling wall124. The second plate portion224has an arcuate protrusion2242protruding from the same side as the first plate portion222. The protrusion2242can be received in the engaging slot146, engaging the sliding unit24. The sliding unit24is engagable with the engaging slot146and includes a main board242, two guiding flanges244, and an engaging flange246. The guiding flanges244protrude from the top surface and the bottom surface of the main board242correspondingly. The engaging flange246protrudes laterally from a side surface of the main board242. The main board242has substantially the same width as the engaging slot146and can be assembled in the engaging slot146. The main board242has pressing strips2422(shown inFIG. 3) formed at a side surface opposite to the engaging flange246to facilitate easy manipulation of the sliding unit24. The two guiding flanges244engage in/with the two guiding slot1462correspondingly. The engaging flange246is located at an end of the side surface, including two adjacent curved latching recesses2462. The latching recesses2462are engaged by corresponding protrusions2242of the holding member22. Hence, the sliding unit24can be secured in different longitudinal positions within the engaging slot146.

The circuit board30is received in the housing10and covers the receiving frame121. The circuit board30includes a peripheral protruding flange32covering the accommodating chamber1252. The connecting terminal40is used to electronically connect the circuit board30and the battery200. The connecting terminal40can be assembled in the accommodating chamber1252and secures the circuit board30. The connecting terminal40includes a plurality of elastic pins42arranged in an array to electronically connect the battery200. The cover50is engagable with the housing10. A display window52and a keypad54are arranged on opposite ends of the cover50correspondingly.

The seal strip60corresponds to matching groove142in shape and is used to assemble in the matching groove142of the sidewall16to cover the battery200. The seal strip60can be made of a resilient material such as rubber. The seal strip60has a touching block62and a connecting column64. The touching block62corresponds to the assembling hole144in size and shape and can be inserted into the assembling hole144. The connecting column64is positioned adjacent to an end of the seal strip60, engaging the fixing aperture148of the sidewall16to secure the seal strip60in the matching groove142.

The battery200can be received in the receiving frame121, the battery200has a plurality of conducting terminals202on the sidewall for contacting the elastic pins42of connecting terminal40.

Referring toFIG. 3, to assemble the battery assembling mechanism100, the connecting terminal40is secured on the protruding flange32of the circuit board30. The holding member22of the sliding assembly20is mounted onto the assembling wall124. The fixing holes2222of the first plate portion222receive the poles1242of the assembling wall124. The protrusion2242of the second plate portion224is latched into the engaging slot146of the assembling wall124. The sliding unit24of the sliding assembly20is installed into the engaging slot146of the housing10, and the two guiding flanges244are inserted into the two guiding slot1462of the assembling wall124. As such, the sliding unit24is longitudinally slidable relative to the engaging slot146. The sliding unit24is limited by a latching recess2462of the engaging flange246. The latching recess2462receives the protrusion2242of the second plate portion224. The sliding unit24can be slid by pulling the sliding unit24. The circuit board30is assembled in the housing10, the circuit board30covers the receiving frame121and the connecting terminal40is received in the accommodating chamber1252of the housing10. The seal strip60can be mounted into the matching groove142of the first sidewall14. The connecting column64of the seal strip60is inserted into the fixing aperture148of the first sidewall14, the touching block62of the seal strip60is latched into the assembling hole144.

FIG. 4throughFIG. 6shows a process of inserting the battery200into the housing10. The seal strip60is opened and the sliding unit24is moved to a position not blocking any portion of the assembling hole144. Therefore, the assembling hole144is opened completely, the sliding unit24is latched by engagement of the protrusion2242with the latching recess2462. The battery200can be placed into the receiving chamber123. The conducting terminals202of the battery200contact with the elastic pins42of the connecting terminal40. After that the battery200is inserted, the sliding unit24can be moved to a position blocking a portion of the assembling hole144. Therefore, one end of the sliding unit24blocks a portion of the assembling hole144and resists a portion of the battery200. Thus, the battery200is latched in the receiving chamber123. The sliding unit24is further latched by engagement of the other engaging of the protrusion2242into the latching recess2462. The seal strip60covers and seals the matching groove142by fixing the connecting column64into the fixing aperture148. The touching block62of the seal strip60is received into the assembling hole144, resisting the battery200. Therefore, the battery200is secured in the housing10.
