Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electronic devices such as portable computers and mobile information terminals,
In particular, the present invention relates to a structure for locking a battery pack serving as a power supply for driving the device to a housing and releasing the lock.

[0002]

2. Description of the Related Art In recent years, portable electronic devices represented by portable computers and mobile information terminal devices have been increasingly thinned in their housings in recent years, and can be easily carried in a bag or the like. .

[0003] This type of electronic equipment is equipped with a battery pack that functions as a driving power supply so that it can be used in a vehicle or outside where a commercial AC power supply cannot be obtained. Since this battery pack needs to be removed from the housing at the time of charging or replacement, conventionally, there has been known an electronic device in which a battery housing portion for detachably housing the battery pack is formed at an end of the housing. The battery accommodating portion is formed by a concave portion that opens toward the outside of the housing, so that the battery pack can be easily removed or attached without disassembling the housing. .

[0004] Conventional electronic devices are equipped with a lock mechanism for locking a battery pack to a battery accommodating portion. As this lock mechanism, a lock mechanism including a pair of lock levers that are detachably hooked to a battery pack is known. Each of these lock levers has a claw projecting from the battery housing. The lock lever is slidably supported by the housing between a lock position where the claw portion is hooked on the battery pack and a release position where the claw portion is detached from the battery pack.

[0005] The lock levers each have knobs for hooking fingertips. The knob is exposed outside the bottom wall at a position adjacent to the battery housing. Therefore, by pressing the knob with a fingertip, the lock lever can be slid to the lock position or the release position, thereby locking and unlocking the battery pack.

[0006]

However, since the conventional lock levers are supported by the housing independently of each other, when the battery pack is removed from the battery housing, the lock levers are locked individually. It is necessary to slide from the position to the release position.

Therefore, when removing the battery pack, it is necessary to simultaneously press the knobs of the lock levers in the unlocking direction with the fingertips of both hands while holding the housing. There is a problem such as poor sex.

The present invention has been made in view of such circumstances, and the first and second lock members are linked to each other to improve the operability thereof, and furthermore, these lock members are linked to each other. The present invention is to provide an electronic device that can prevent buckling of the interlocking member and can simplify the structure of the interlocking member.

[0009]

According to one aspect of the present invention, there is provided an electronic apparatus according to the present invention, comprising: a housing having a pack housing; and a removably housed in the pack housing of the housing. A pack component having first and second engaging portions; and a locking position supported by the housing and engaged with the first and second engaging portions of the pack component, respectively.
First and second lock members movable over a release position at which the first lock member is disengaged from the first and second engagement portions; provided on the housing; An operating member for moving the second lock member to the lock position, and an interlocking member that moves following the first lock member. Have. Then, the interlocking member moves when the first lock member is moved from the lock position to the release position.
The second lock member is brought into contact with the second lock member and pulled from the lock position toward the release position, and when the second lock member is pressed from the lock position toward the release position, The second lock member moves away from the interlocking member, and the second lock member can move independently against the urging force of the elastic member.

In such a configuration, when the first lock member is moved from the lock position to the release position when removing the pack component from the pack storage portion, the first lock member is moved to the first position.
Following the movement of the lock member, the interlocking member starts moving, and the second lock member is pulled from the lock position to the release position via the interlocking member. Therefore, the first
The movement of the lock member is transmitted to the second lock member via the interlocking member, and the first and second lock members are moved from the lock position to the release position in synchronization with each other.

Therefore, it is not necessary to manually operate the first and second lock members individually, and the operability when unlocking the pack components is improved. In addition, according to the above configuration, the interlocking member pulls the second lock member toward the release position, so that the force at the time of unlocking the pack component is received as a pull load. With it,
For example, even when the second lock member exposed to the pack storage portion is erroneously pressed from the lock position to the release position in a state where the pack component is removed from the pack storage portion, the second lock member Moves independently without the interlocking member, and the movement of the second lock member is not transmitted to the interlocking member. For this reason, the interlocking member is not compressed between the first lock member and the second lock member, and although the first and second interlocking members are interlocked with each other, Buckling can be prevented from acting.

According to another aspect of the present invention, there is provided an electronic apparatus according to a ninth aspect of the present invention, comprising: a housing having a bottom wall and a peripheral wall connected to the bottom wall; formed on the housing and connected to the bottom wall and the peripheral wall. A battery housing that has been opened and opened; and a battery pack removably mounted in the battery housing;
A claw portion exposed to the battery accommodating portion, wherein the claw portion is slidable in the same direction with each other over a lock position where the claw portion is hooked on the battery pack and a release position where the claw portion is detached from the battery pack. First and second locking members supported on the bottom wall of the housing; and an interlocking member slidably supported on the bottom wall of the housing and interlocking the first and second locking members. I have. The first lock member has an operation unit exposed to the outside of the bottom wall, and is manually slid to the lock position or the release position by manually operating the operation unit. The second lock member is constantly biased toward a lock position via a spring, and the interlocking member slides following the first lock member, and is slid relative to the second lock member. When the first lock member is slid from the lock position to the release position, the interlocking member is slidably supported by the bottom wall.
The second lock member is detachably engaged with the second lock member from the direction of the lock position, and the second lock member is pulled toward the release position. In such a configuration, when the first lock member is slid from the lock position to the release position when the battery pack is removed from the battery housing portion, the interlocking member moves following the first lock member. Starting, the second lock member is pulled from the lock position toward the release position via the interlocking member. Therefore, the movement of the first lock member is transmitted to the second lock member via the interlocking member, and
And the second lock member is slid from the lock position to the release position in synchronization with each other.

Therefore, there is no need to manually operate the first and second lock members individually, and the operability when releasing the lock of the battery pack is improved. In addition, according to the above configuration, the interlocking member pulls the second lock member toward the release position, so that the force at which the battery pack is unlocked is received as a tensile load. Also,
Since the second lock member returns to the lock position by the urging force of the spring, when the operation of the first lock member is released, the interlocking member moves following the second lock member. Therefore, this time, the first lock member is pulled from the release position to the lock position via the interlocking member.

Further, for example, when the second lock member is pressed from the lock position to the release position via the claw portion exposed to the battery storage portion in a state where the battery pack is removed from the battery storage portion, Since the interlocking member is engaged with the second lock member from the direction of the lock position, the second lock member moves alone without the interlocking member, and the second lock member The movement is not transmitted to the interlocking member. For this reason, the interlocking member is not compressed between the first lock member and the second lock member, and although the first and second interlocking members are interlocked with each other, Buckling can be prevented from acting.
