DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery pack attaching / detaching structure, and more particularly to a battery pack attaching / detaching structure for a small wireless device such as a portable telephone.

[0002]

2. Description of the Related Art FIG. 5 is an external view of a conventional battery pack attaching / detaching structure, FIG. 6 is a sectional view showing a state where a battery pack is unlocked or before being stored, and FIG. It is sectional drawing which shows the time of pack storage. The structure of this conventional example will be described.
The battery pack 8 is provided with a claw 15 and the battery pack 8 is provided with a groove 9 for engaging with the claw 15.
A fixing claw 15 'and a groove 9' of the battery pack 8 engaging with the fixing claw 15 'are provided. When storing the battery pack 8, first, the fixing claw 15 ′ of the housing is engaged with the groove 9 ′ of the battery pack, and the battery pack 8 is brought into a position where the claw 15 matches the groove 9 of the battery pack 8. Into the claw 15 and the groove 9
Is engaged. At this time, there is a power supply terminal 18 projecting from the bottom of the housing, which serves as a hook for removing the battery pack. Therefore,
At the time of storage, the bottom of the battery pack 8 presses the spring of the power supply terminal 18. To release the lock, the lock release knob 1 is slid horizontally to release the engagement between the claw 15 of the lock release knob and the groove 9 of the battery pack 8 and the contact portion between the housing 14 and the battery pack 8. The battery pack 8 is hooked up by the spring repulsive force of the power supply terminal 18 and the battery pack 8 is released.

[0003]

A first problem in the above-mentioned prior art is that when the battery pack is released, the spring rebound of a power supply terminal, which is a contact point between the housing and the battery pack, is used. When released, the power terminal must protrude from the housing so that the power terminal contacts the battery pack when stored. In order to make this operation smooth, it is necessary to consider the height and width of the protrusion, the elastic modulus of the spring, etc., which greatly restricts the shape and position of the power supply terminal, which hinders the degree of freedom in design. Is to put it.

[0004] A second problem in the prior art is that when the battery pack is stored, the power supply terminal projecting when the battery pack is released,
Because the battery pack is pressed down by the battery pack, if the battery pack is stored for a long period of time, the power supply terminal may rebound due to the material of the power supply terminal, the weight of the battery pack, or the unevenness between the housing and the battery pack. When losing power and releasing,
That is, it may not hook up. That is, it lacks the reliability and reliability of attachment and detachment.

Accordingly, it is an object of the present invention to provide a battery pack mounting / removing structure utilizing the repulsive force of a power supply terminal in the prior art which has the above-mentioned problems. An object of the present invention is to provide a structure for mechanically releasing the engagement between a battery pack and a housing without using a springy repulsion force.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a battery pack attaching / detaching structure of the present invention, that is, a claw portion in which an unlocking knob portion engages with a slot of an electronic device, and a claw portion thereof A spring connected to the housing of the electronic device on the opposite side, and a convex portion having a through hole for connecting to the hook-up portion on the lower side, wherein the hook-up portion has a U-shaped main body and a lock. In order to connect with the release knob portion, a connection portion provided at one end of the U-shaped main body and having an oval hole that matches the through hole of the lock release knob portion, and the oval hole and the through hole A penetrating pin, a columnar projection projecting laterally at the center of the U-shaped body, and a tip provided at the other end of the U-shaped body for contacting the battery pack and pushing it upward. A rail supporting the cylindrical projection of the hook-up portion, the support comprising: Comprises a stopper for stopping the cylindrical protrusion of the hookup unit, it can be achieved by detaching structure of the battery pack. Also, if the oblong hole is formed in a concave shape, the rotation of the hook-up block portion and the lock knob portion becomes smooth, and further, if the U-shaped body is formed in a U shape, the rail of the support portion is formed. The hook-up part can move smoothly on the top. Mechanically, by adding a hook-up portion and a support portion, the unlocking knob is slid horizontally to unlock the battery pack from the housing, and at the same time, the hook connected to the unlocking knob portion by the pin. The up portion rotates, and the columnar protrusion provided on the hook-up slides on the R-shaped rail surface provided on the housing, and the tip of the hook-up portion is moved from the escape route of the housing to the housing. Since the battery is protruded from the body and pushes up the battery pack, the shape and position of the power supply terminal can be freely set, and the reliability and reliability are improved.

[0010]

According to the battery pack attaching / detaching structure of the present invention described above, a hook-up mechanism is added to the battery pack attaching / detaching structure and linked with the lock release mechanism. Therefore, the design is not restricted by the shape and position of the power supply terminal. The degree of freedom is expanded. The reason is that the hook-up of the battery pack is performed mechanically without using the springy elastic force of the power supply terminal. In addition, the battery pack should be hooked up without being affected by the power supply terminal, the weight of the battery pack, the variation in fitting of the battery pack to the housing, etc. by hooking up without using the power supply terminal. And the reliability and reliability of attachment and detachment are improved. The reason is that the battery pack is hooked up mechanically without using the springy elastic force of the power supply terminal.
