Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device system including a portable electronic device such as a book-type portable computer, and an extension station for expanding the functions of the electronic device. The present invention relates to an extension device used when connecting various external peripheral devices to an electronic device.

[0002]

2. Description of the Related Art In a portable computer called a book type computer, the size and weight of a computer main body have been reduced in order to enhance portability.

By the way, as the size of the computer body becomes smaller, it becomes more difficult to secure a space for attaching connectors for connecting external peripheral devices and a space for accommodating a hard disk drive or a floppy disk drive. For this reason, recent compact portable computers are equipped with an expansion port on the back of the computer body. By connecting an expansion station called a port replicator to this expansion port, it is inferior to a stationary computer. It is possible to secure extensibility that does not occur.

[0004] This type of expansion station includes various connectors for connecting various external peripheral devices such as an external keyboard, an external display or a printer, and a P-type connector.
It has a card storage unit for storing a communication card such as a CMCIA card.

The extension station has a mounting portion on which the computer main body is removably mounted. The mounting portion has a flat mounting surface of a size corresponding to the computer main body, and an extension port connector is arranged at a rear end of the mounting surface. The expansion port connector corresponds to the expansion port of the computer main body, and is electrically connected to the connectors.

The extension port connector faces the extension port of the computer when the computer is placed on the mounting surface. Then, when the computer body placed on the mounting surface is slid toward the extension port connector, the extension port fits into the extension port connector, and the portable computer and the extension station are electrically connected by this fitting. It has become so.

In this case, since the sliding operation of the computer body is performed manually by the operator, there is a possibility that the computer may shift or tilt from a predetermined position on the mounting surface during the sliding operation. Then
Expansion port and expansion port connector do not fit smoothly,
This may cause deformation of the connector and poor connection.

For this reason, the conventional extension station is provided with the engagement projection protruding from the mounting surface. The engaging projection is supported on the mounting surface so as to be movable in the sliding direction of the computer main body, and the extension port and the expansion port connector are aligned by hooking the bottom wall of the computer main body on the engaging projection. It has become so.

However, according to the conventional extension station, the operator needs to slide the computer body toward the extension port connector while checking the positions of the computer body and the engagement projection. for that reason,
There is a problem that the operability when sliding the computer body is deteriorated.

In order to cope with this problem, recently, a lock pin which is rotatable between a lock position protruding above the mounting surface and a lock release position retracted from the mounting surface is provided on the mounting portion. An extension station has been developed in which a detection lever for detecting the sliding position of the computer main body on a surface is arranged, and the detection lever and the lock pin are interlocked with each other via an interlocking fitting.

In this extension station, when the computer main body placed on the mounting surface is slid toward the expansion port connector, the computer main body comes into contact with the detection lever, and the detection lever rotates in a direction to retract from the mounting surface. Is done. The movement of the detection lever is transmitted to the lock pin via the interlock, and the lock pin rotates from the unlocked position to the locked position. Therefore, the lock pin starts to protrude above the mounting surface following the slide of the computer main body, and engages with the bottom wall of the computer main body when the expansion port reaches just before the expansion port connector. By this engagement, the relative positions of the expansion port and the expansion port connector are adjusted, and the expansion port and the expansion port connector are fitted with high precision.

According to this configuration, the lock pin projects on the mounting surface when the expansion port of the computer reaches just before the expansion port connector, so that the operator does not care about the presence of the lock pin. The computer main body can be slid, and the connection work between the portable computer and the extension station can be easily performed.

[0013]

According to the extension station having the above structure, the lock pin and the detection lever are arranged apart from each other in the depth direction of the mounting surface, that is, in the sliding direction of the computer main body. For this reason, a plurality of support portions for individually supporting the lock pins and the detection levers must be formed on the mounting portion of the extension station, which complicates the configuration of the mounting portion.

Moreover, since a special interlocking fitting for interlocking the lock pin and the detection lever is required, the number of parts is increased by the amount of the interlocking fitting. As a result, the cost of the extension station is increased in addition to the complicated configuration of the mounting section, and there is still room for improvement in this regard.

The present invention has been made in view of such circumstances, and an object of the present invention is to connect an electronic device body to an extension station reliably and easily.

At this time, the housing 4 is mounted on the mounting surface 36 such that the seat 19 of the bottom wall 4a is located near the stoppers 130 and 131, and the left and right steps 22a and 22b of the bottom wall 4a. To the first and second guide rails 4
Hook on the latter half of 4,45. Thereby, the housing 4 is positioned in the width direction of the mounting surface 36, and the first
And the second expansion connector 42 face each other.

Next, the portable computer 1 is slid toward the second expansion connector 42 by the manual operation of the operator. At this time, the upper surface 133c of the protrusion 133 of the stopper 130, 131 is in contact with the bottom wall 4a of the housing 4, but since this upper surface 133c is made of the same synthetic resin as the housing 4, There is no significant frictional resistance in the part. In addition, since the upper surface 137a of the anti-slip member 135 connected to the protrusion 133 is separated from the bottom wall 4a of the housing 4, the anti-slip member 135 does not hinder the sliding of the housing 4, and the portable computer 1 Can be smoothly slid toward the second expansion connector 42.

[0139] The bottom surface 14a of the pack-shaped device 13 mounted in the pack accommodating portion 12 of the housing 4 is the bottom wall 4a of the housing 4.
From the first guide rail 44 on the mounting surface 36.
And face each other. However, the first guide rail 4
4 has the concave portion 46 that avoids the pack-shaped device 13, so that the pack-shaped device 13 does not ride on the first guide rail 44, and the inclination of the portable computer 1 on the mounting surface 36 can be prevented.

When the portable computer 1 is slid toward the second extension connector 42, the second front leg 15 b at the front end of the housing 4 is moved to the guide groove between the second guide rail 45 and the auxiliary rail 47. 48 slidably fits. Thereby, the front portion of the housing 4 is positioned with respect to the mounting surface 36.

Therefore, even in a situation where the first guide rail 44 cannot guide the first front leg 15a of the housing 4 due to the presence of the concave portion 46 as described above, the guide property of the portable computer 1 is sacrificed. Therefore, the sliding direction of the portable computer 1 can be accurately guided.

When the first expansion connector 26 of the portable computer 1 reaches just before the second expansion connector 42, the rear wall 4d of the housing 4 contacts the pressing surfaces 57 of the release members 50 and 51, and this release member 50 and 51 are slid from the second slide position to the first slide position.

When the release members 50 and 51 are slid toward the first sliding position, the lock lever 63 is also moved to the release members 50 and 5 as shown in FIGS.
Slide to follow 1. The cam surface 66 of the lock lever 63 is provided with a guide pin 70 protruding from the holding bracket 60.
The position of the guide pin 70 and the cam surface 66 is relatively changed by the sliding of the lock lever 63. For this reason, the lock lever 63
Based on the shape of the cam surface 66, it is rotated upward from the unlocked position to the locked position, and the engaging projection 64 of the lock lever 63 is projected onto the mounting surface 36 through the openings 49 of the lock portions 44a and 45a. You.

When the first expansion connector 26 of the portable computer 1 reaches just before the second expansion connector 42, the fitting hole 23 of the bottom wall 4 a of the housing 4 is
a, 45a. Therefore, the engaging protrusion 64 of the lock lever 63 is fitted into the fitting hole 23 of the housing 4, and the portable computer 1
The connector is slid toward the second expansion connector 42 while maintaining the engagement with the connector.

By this slide, the first extension connector 26 and the second extension connector 42 are fitted with each other,
The portable computer 1 is electrically connected to the extension station 30. Since the engagement protrusion 64 of the lock lever 63 is fitted in the fitting hole 23 of the housing 4, sliding of the portable computer 1 in a direction away from the second expansion connector 42 is restricted, and 1 is locked on the mounting surface 36.

When the first expansion connector 26 reaches just before the second expansion connector 42, the first expansion connector 26
The third locking portions 74a to 74c enter the insertion ports 17 and 20 of the first to third engaging portions 16a to 16c of the housing 4 and are hooked on the bottom wall 4a of the housing 4. For this reason, the portable computer 1 is pressed down on the mounting surface 36,
The first expansion connector 26 and the second expansion connector 42
The connection state with is maintained.

Next, a procedure for removing the portable computer 1 from the extension station 30 will be described.

First, by operating the lock cylinder 128, the linkage lever 125 is slid from the first slide position to the second slide position.
25, the lock of the eject lever 82 is released.
That is, when the link lever 125 is slid to the second sliding position, the locking piece 118 of the lock lever 116 is released from the opening edge of the locking hole 126, and the lock lever 116 is moved from the locked position to the unlocked position. It shifts to a state where it can freely rotate toward.

Next, a fingertip is hooked on the tip end 111a of the operation lever 111 exposed on the right side wall 31b of the main body 31, and the operation lever 111 is turned from the first rotation position to the second rotation position. To rotate. Then, the distal end portion 111 a of the operation lever 111 is pulled toward the front of the mounting surface 36. As a result, the eject lever 8
2 is rotated from the standby position toward the eject position.

As shown in FIG. 18, the eject lever 8
2 is rotated toward the eject position, the tongue 9
4 is disengaged from the engaging portion 95 of the slide lever 81 and the lock of the slide lever 81 is released.

At the same time as the lock of the slide lever 81 is released, the connecting portion between the eject lever 82 and the toggle link 103 approaches the second arm portion 86 of the slide lever 81, and the toggle link 103 with respect to the straight line X1.
Becomes smaller. For this reason, the toggle link 10
The third second end 103 b is guided by the link hole 106 and is pushed out toward the tip of the second arm 86, and the link pin 105 abuts against the end of the link hole 106.

As a result, the rotational force of the eject lever 82 is transmitted to the slide lever 81, and the slide lever 81 starts sliding from the first operation position to the second operation position. At this time, the toggle link 103 is turned from a position inclined with respect to the second arm portion 86 to a position along the second arm portion 86, so that the eject lever 82 is turned. The force to be applied is doubled to about three times by the toggle link 103 and transmitted to the slide lever 81.

First arm 85 of slide lever 81
Are connected to the sliders 52 of the release members 50, 51, so that when the slide lever 81 is slid from the first operation position to the second operation position, the release members 50, 51 are followed. Are forcibly slid from the first slide position to the second slide position.
Therefore, the housing 4 of the portable computer 1 is pushed out by the pressing surfaces 57 of the release members 50 and 51 in a direction away from the second extension connector 42, and the first extension connector 26 and the second extension connector 42 are fitted. Is canceled.

At the initial stage when the release members 50 and 51 start sliding toward the second sliding position, the turning force of the eject lever 82 is increased to about three times by the toggle link 103 as described above. The fitting force between the first extension connector 26 and the second extension connector 42 can be easily overcome, and the fitting between the first extension connector 26 and the second extension connector 42 can be smoothly released. .

The release member 5 is moved to a position where the engagement between the first expansion connector 26 and the second expansion connector 42 is released.
When 0 and 51 are slid, the roller 99 of the eject lever 82 comes into contact with the cam portion 108 of the slide lever 81 as shown in FIG. By this abutment, the slide lever 81 moves to the second
The slide lever 81 is slid toward the operation position of
Slide stroke is enlarged.

As a result, the portable computer 1 on the mounting surface 36 is pushed out in a direction away from the second expansion connector 42 through the release members 50 and 51 at a stretch, and the first to third terminals on the mounting surface 36 are released. Locking parts 74a-7
4c is the first to third engagement portions 16a to 16c of the housing 4.
Is pulled out from the insertion ports 17 and 20 of FIG.

[0157] As shown in FIG.
When 51 is slid toward the second slide position,
The lock lever 63 also moves forward following the release members 50 and 51. Therefore, the guide pin 70 moves to the rear end of the cam surface 66 of the lock lever 63, and the pushing up of the lock lever 63 by the guide pin 70 is released.

As a result, the lock lever 63 is rotated to the unlock position at the same time when the release members 50 and 51 are slid to the second slide position, and the engagement protrusion 64 is
Is pulled out of the fitting hole 23 of the housing 4.

Therefore, the first expansion connector 26
Following the disengagement of the second extension connector 42 with the
The lock of the housing 4 with respect to the mounting surface 36 is released, and the portable computer 1 can be removed from the extension station 30.

As shown in FIG. 5, the mounting surface 36 is inclined downward from the rear end 36b where the second expansion connector 42 is disposed to the front end 36a. For this reason, when the portable computer 1 is pushed out through the release members 50 and 51 as described above, the portable computer 1 slides down along the mounting surface 36, and the housing 4 may collide with a top plate of a desk or the like. There can be.

However, since the pair of stoppers 130 and 131 are disposed on the mounting surface 36, when the portable computer 1 is pushed in a direction away from the second expansion connector 42, the bottom wall of the housing 4 The seat 19 of 4a is caught by the non-slip member 135 of the stopper 131, 131, and the portable computer 1 is prevented from falling off from the mounting surface 36.

Specifically, when the portable computer 1 is pushed in a direction away from the second extension connector 42, first, the front end of the seat portion 19 first comes into contact with the non-slip member 135.
And the portable computer 1 is subjected to a braking frictional force. Following this, the seat 19
Of the portable computer 1 is stopped, and the slide of the portable computer 1 is stopped.

Therefore, in order to enhance the operability of the portable computer 1, even when the mounting surface 36 is inclined forward and downward, when the portable computer 1 is removed, the mounting surface of the portable computer 1 is inadvertently set. 36 does not fall off, and handling becomes easy.

In the extension station 30 having such a configuration, the engagement protrusion 64 of the lock lever 63 fitted into the fitting hole 23 of the portable computer 1 is such that the portable computer 1 When the portable computer 1 is slid to the position immediately before, it protrudes above the mounting surface 36 for the first time, so that the operator can perform the sliding operation of the portable computer 1 without worrying about the presence of the engagement protrusion 64. Therefore, the connection work between the portable computer 1 and the extension station 30 can be easily performed.

Further, since the lock lever 63 is supported by the release members 50 and 51,
The zero upper cover 33 only needs to support the release members 50 and 51 only. Moreover, the lock lever 6
When the slide member 3 is slid following the release members 50 and 51, the lock member 70 is rotated to the unlock position and the lock position based on the contact with the guide pin 70. It just needs to be fixed to. For this reason, a complicated mechanism for rotating the lock lever 63 is not required.

Further, according to the above configuration, when the portable computer 1 is connected to the extension station 1,
Since the slide position of the portable computer 1 is originally detected by using the release members 50 and 51 for pushing out the portable computer 1, a dedicated mechanism for detecting the slide position of the portable computer 1 needs to be arranged on the mounting surface 36. There is no.

Therefore, there is an advantage that the configuration of the mounting section 35 can be simplified and the cost of the extension station 30 can be reduced.

Note that the present invention is not limited to the first embodiment, and FIGS. 23 to 25 show a second embodiment of the present invention.

In the second embodiment, a lock lever 15 for locking the portable computer 1 to the mounting surface 36 is used.

The rear end 150b of the lock lever 150
In the state where the release members 50 and 51 are slid to either the first slide position or the second slide position, the release members 50 and 51 are located in the convex portion 40 at the rear end of the mounting surface 36. A vertical guide wall 153 extending in the depth direction of the mounting surface 36 is integrally formed inside the projection 40. The lower end of the guide wall 153 forms a cam surface 154, and the sliding protrusion 151 of the lock lever 150 is slidably in contact with the cam surface 154.

The cam surface 154 is inclined downward from the front end to the rear end of the guide wall 153. Therefore, as shown in FIG. 23, when the release members 50 and 51 are slid to the second sliding position, the rear end 150b of the lock lever 150 is disengaged from the front end of the cam surface 154, and therefore, The lock lever 150 is rotated to the unlock position.

As shown in FIGS. 24 and 25, when the release members 50 and 51 are slid from the second slide position to the first slide position, the slide projection 151 of the lock lever 150 is brought into contact with the cam surface 154. The rear end 150b is slidably contacted, and the rear end 150b is pressed downward according to the shape of the cam surface 154. By this pressing, the lock lever 150 is rotated from the unlocked position to the locked position, and the engaging projection 64 of the lock lever 150 is fitted into the fitting hole 23 of the portable computer 1.

According to the second embodiment having such a structure, when the lock lever 150 is slid following the release members 50 and 51, the lock lever 150 is brought into contact with the cam surface 154 to release the lock release position and the lock position. Since the cam surface 154 is rotated to the lock position, the cam surface 154 may be formed on the upper cover 33, and does not need to have a complicated movable structure. Therefore, a complicated mechanism for rotating the lock lever 150 is not required at all, and the same effect as that of the first embodiment can be obtained.
