Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a battery attachment/detachment mechanism used as a power source for, for example, a video system device.

(Prior Art) As a structure in which a packaged battery can be attached to and detached from a mating member, there are structures proposed in Utility Model Application No. 132409/1982 and Application No. 52346/1983.

The structure proposed in Utility Model Application No. 61-132409 is a protrusion that engages the side surface of the battery (the mounting surface is the surface) and the side surface of the camera casing (the surface to be mounted is the surface) by sliding these sides together. Furthermore, a locking member for maintaining the engaged state is provided on the camera housing side. Also, Jitsugan Sho 63-5234
The structure proposed in No. 6 has protrusions that engage with each other by sliding on the surface on which the battery is attached and the surface on which the battery charger is attached, and a locking hook on the surface on which the battery charger is attached. To attach the battery, a recess into which the locking hook fits is provided on the surface.

(Problems to be Solved by the Invention) In the structure proposed in Utility Application No. 132409/1980, the battery and the mating member are attached and detached by sliding the battery linearly relative to the mating member. Since the battery is prevented from being removed by a locking member that rotates in a direction different from the sliding movement, it is not possible to attach/detach the battery and release the lock in a continuous smooth movement. .

Furthermore, in the structure proposed in Utility Application No. 63-52346, since the recess and the hook are engaged only by the elastic force of the locking hook, the battery may be damaged if vibration or a somewhat strong force is applied. It comes off from the mating member.

In addition, in any of the preceding examples, since the terminals are exposed on the surface when installing the battery, it is necessary to attach vinyl tape, etc. to the terminals to prevent short circuits, and it is necessary to attach or remove this tape. But it takes so much time and effort.

Furthermore, in any of the precedent cases, when an operation is performed to release the locked state, it is possible to intuitively know whether the locked state is actually released or not, and it is not possible to pull out the battery with more force than necessary. There is.

(Means for Solving the Problems) In order to solve the above problems, in the first invention, the battery is mounted on a surface, and the mating member is mounted on a guide F that is inclined with respect to the sliding direction on either one of the surfaces. A locking protrusion having a surface is provided, and a lever is provided on the other of the battery and the mating member, a portion of which engages with the locking protrusion by the elastic force of a spring, and a lever extending in the same direction as the sliding direction of the battery. A release button is provided which releases the engaged state of the lever by moving against the spring.

In addition, in the second aspect of the invention, the battery, which is attached to and detached from the mating member by a sliding operation, is attached by providing a terminal on the surface and a cover that covers the terminal and is slidable in the same direction as the attachment and detachment direction of the battery.

Furthermore, in the third aspect of the invention, the battery is attached by attaching a slideable cover that covers the terminal provided on the surface with a force that allows the battery to slide relative to the mating member when the engagement between the battery and the mating member is released. It was biased in the closing direction by a spring.

(Function) Since the direction in which the lock release button is operated is the same as the direction in which the battery is installed and removed, it is possible to perform everything from installation and removal of the battery to unlocking in a series of operations. The cover automatically opens when the cover is attached, and when the lock is released, the spring that biases the cover in the closing direction causes the battery to move relative to the other member, indicating that the lock has been released. You will know it intuitively.

(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

Since the operation is the same as that of attaching the battery 50 to the
The operation of attaching the battery 50 to the TV tuner 30 will be described below.

First, to install the battery 50, turn the surface from direction a in FIG.
The V tuner 30 to be mounted is pressed against the surface. At this time, the engaging parts 55a, 56a of the battery 50 and the engaging parts 301a, 302a of the TV tuner 30 are in a position where they do not overlap.

At this time, the protrusion 308 of the lever 307 is located within the four portions 57 of the surface on which the battery 50 is attached. After that, the battery 50 is slid in the b direction. Then, the engaging portions 55a and 56a enter the engaging portions 301a and 302a, and the protruding portion 308 abuts the guide surface 59 of the protruding portion 58, causing the lever 30 to
7 rotates in the direction of arrow C in FIG. 6 against the spring, and when it passes the apex of the guide surface 59, the protrusion 308 falls inside the protrusion 58 and is locked. In addition, in parallel with the above movement, as shown in FIGS. 8(A) and 8(B), the protrusion 3 formed on the plate 300 of the TV chew 30
03 contacts the end of the terminal cover 62 and slides the battery 50 in the direction of the arrow d, the cover 62 slides in the opening direction against the spring 63 and the terminal 61 is exposed. A terminal 304 on the TV tuner 30 side contacts this terminal 61.

On the other hand, to remove the battery 50 from the TV tuner 30, as shown in FIG. 6, slide the release button 311 in the direction of arrow e. Then, the lever 307 rotates in the direction of arrow C against the spring, and the engagement between the projections 58 and 308 is released.

Here, since the elastic force of the spring 63 is set to be relatively strong, when the engagement between the protrusions 58 and 308 is released, the elastic force of the spring 63 will slightly damage the battery 50 or the TV tuner 30. You can tell when the lock is released because it slides. Thereafter, the battery 50 is removed from the TV tuner 30 by sliding the battery 50 in the opposite direction.

9 and 10 show the case where the TV tuner 30 is omitted and the battery 50 is directly attached to the video deck 10. Due to this structure, such a combination is possible.

(Effects) As explained above, according to the present invention, the structure of the locking mechanism in the battery attachment/detachment mechanism can be easily and reliably locked, and since the operating direction of the lock release button and the direction of battery attachment/detachment are the same, it is possible to continuously You can do everything from attaching and detaching the battery to unlocking with just a few steps, making it extremely easy to use.

In addition, when installing the battery, a terminal cover is provided on the surface that automatically opens and closes in conjunction with the installation of the battery, so there is no need to cover the terminals with vinyl tape or the like when stocking them.

Furthermore, the elastic force of the spring that biases the cover in the closing direction causes the battery to move relative to the mating member when the lock is released, so you can intuitively know that the lock has been released, and you can avoid unreasonable situations. There is no need to pull out the battery with force or repeat the removal operation many times.
