## Background
BACKGROUND
1. Technical Field
The present disclosure relates to an electronic device and a holding mechanism applied therein.
2. Description of the Related Art
Components of an electronic device, such as a battery, an internal optical disc drive, SD-cards, and like this, are usually fixed in the electronic device. A mechanical holding mechanism is often used for fixing those components in the electronic device and ejecting them from the device in response to user's operations. However, a conventional mechanical holding mechanism often needs exact and unerring operations that confuse users.
Therefore, what is needed is a holding mechanism applied in an electronic device to overcome the above-mentioned shortcomings.

DETAILED DESCRIPTION
Referring to FIG. 1, an electronic device 9 includes a main body 100 and a holding mechanism 200 mounted in the main body 100. In the exemplary embodiment, the device 9 is a notebook computer. In an alternative embodiment, the device 9 can be, for example, a mobile phone, an e-reader, a PDA, or the like. The holding mechanism 200 is configured to hold a battery, an SD card, an internal optical disc drive, or a wireless card in the device 9.
Referring to FIG. 2, the holding mechanism 200 includes a housing 10, a stopper member 40, a first elastic member 41, a carriage 50, a second elastic member 51, and a button 30.
Referring to FIG. 3, an L-shaped wall 15 protrudes from the bottom of the housing 10, and cooperates with sidewalls of the housing 10 to form an L-shaped accommodating space 13. In this embodiment, the housing 10 includes a first sidewall 16, a second sidewall 18 opposite to the first sidewall 16, a third sidewall 21, and a fourth sidewall 22 formed between the first sidewall 16 and the second sidewall 18, and an opening 11 is defined in the second sidewall 18. The L-shaped wall 15 is connected to the first sidewall 16 and the third sidewall 21 to form the L-shaped accommodating space 13 with all the sidewalls 16, 18, 21 and 22.
The space 13 accommodates the stopper member 40, the first elastic member 41, the carriage 50, the second elastic member 51, and the button 30 (shown in FIG. 2). A sliding groove 102 is defined in the L-shaped wall 15, communicating with the L-shaped accommodating space 13. The stopper member 40 is slidably received in the sliding groove 102 through the first elastic member 41. The carriage 50 is slidably connected to the first sidewall 16 by the second elastic member 51. The button 30 is configured to move the stopper member 40 along the sliding groove 102.
One end of the first elastic member 41 is fixed on a protrusion 43 of the stopper member 40, and the other end of the first elastic member 41 is fixed on the third sidewall 21. A bushing 12 protrudes from an inner surface of the second sidewall 18 and is configured for receiving the button 30. One end of the button 30 passes through an assembly hole 19 defined in the second sidewall 18.
One end of the second elastic member 51 is fixed on a first protrusion 14 protruding from an inner surface of the first sidewall 16, and the other end of the second elastic member 51 is fixed on a second protrusion 53 protruding from the carriage 50.
The carriage 50 is slidably received in the accommodating space 13 of the housing 10. A ridge 52 protruding from the carriage 50 abuts against one free end of the stopper member 40, to retain the carriage 50 in the accommodating space 13 in a retracted position. In the embodiment, the carriage 50 is configured for receiving a battery 20 through the opening 11. The carriage 50 is also an electrode connector for electrically connecting to the battery 20. In an alternative embodiment, the carriage 50 can be a CD driver for receiving a CD-ROM, or a connector for fixing a SD card or a wireless card in the device 9.
Referring to FIG. 4, the stopper member 40 includes a first sloping surface 42 that defines two restriction slots 45. The slots 45 are substantially parallel to each other. The button 30 includes a distal end 31. A second sloping surface 33 is defined on the distal end 31. Two projecting portions 32 protrude from the second sloping surface 33. The first sloping surface 42 and the second sloping surface 33 abut against each other. The projecting portions 32 are slidably received in the two restriction grooves 45.
Referring to FIG. 5, normally, the battery 20 is retained in the carriage 50. To remove the battery 20, the button 30 is pushed into the housing 100. The stopper member 40 is then urged by the button 30 to move away from the carriage 50. During the process, the first elastic member 41 is compressed. After the stopper member 40 disengages from the carriage 50, the second elastic member 51 pushes the carriage 50 to eject the battery 20 fixed in the carriage 50 out through the opening 11.
To install the battery 20 in the device 9, the battery 20 is pushed through the opening 11 to drive the carriage 50, and the carriage 50 pushes and compresses the second elastic member 51. At the same time, the carriage 50 also applies force to the stopper member 40, and the stopper member 40 pushes and compresses the first elastic member 41. Finally, the stopper member 40 blocks the carriage 50 when a restoring force of the first elastic member 40 pulls the end of the stopper member 40 to insert into the ridge 52. Therefore, the battery 20 is inserted into the carriage 50 and fixed in the device 9.
It is understood that the disclosure may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the disclosure is not to be limited to the details given herein.
