Description

[Detailed Description of the Invention] The present invention relates to a lockable casing mechanism for slidingly connecting the main body of a portable wireless device to a battery pack or the like.

The battery pack of a portable wireless device can be easily removed from the main body by sliding it when the battery runs out or when using a device with a large power capacity.

By the way, when a portable wireless device is carried around all the time and used in various positions, the removable battery pack is appropriately locked so that it does not come off easily when the device is tilted. It is desirable that the lock can be easily released during removal.

The present invention was proposed in response to these demands, and involves connecting two casings in a sliding manner by fitting protrusions and grooves, and also by providing a protrusion on the side of one casing. A recess is provided in the elastically deformable tongue on the other side of the casing, and a locking function is provided that automatically locks or unlocks the mating when the protrusion and recess are connected or disconnected. The present invention provides a housing connection mechanism.

The present invention will be explained below with reference to the embodiments shown in the drawings. In Fig. 1, a portable wireless device to which the present invention is applied is a U-shaped main body 1, a front cover 2 and a rear cover 3, respectively.
A top lid 4 is attached to the main body 1 and the covers 2 and 3, and the top lid 4 is provided with knobs 5 and 6 for adjusting volume and sound quality, an antenna 7, and the like.

The main body 1 is also provided with a transmitting switch 8, a channel switching switch (not shown), etc., and a battery pack 9 containing batteries is removably attached to the lower part of the main body 1.

Next, in FIGS. 2 to 4, the bottom part 10 of the main body 1
A protrusion 11 with an L-shaped cross section and a protrusion 12 with an inverted-shaped cross section are provided back to back and protrude parallel to the longitudinal direction, and a stopper member 13 is provided at one end of these protrusions 11 and 12. .

On the other hand, the above-mentioned protrusion 11 is provided on the lid portion 14 above the battery pack 9.
．． 12, a groove 15 having an L-shaped cross-section and a groove 16 having an inverted-shaped cross-section are similarly provided in parallel, and further a stopper member 13 is provided at one end of these grooves 15, 16 toward the cover 14. A notch 17 having the same width as that is provided.

In addition, a protrusion 18 with a circular cross section is protruded from the center of the main body bottom 10 in front of the stopper member. A resin tongue piece 19 is formed to be elastically deformable using a portion thereof, and a recess 20 having a circular cross section is formed in this tongue piece 19.

As a result, when connecting the main body 1 and the battery pack 9, the battery pack 9 is inserted into the protrusion 11.12 of the main body 1 from the side opposite to the stopper member 13 through the cut 17 and the groove 15.16, and furthermore, in this state, the battery pack 9 is slid in the longitudinal direction so that the stopper member 13 comes into contact with the end of the notch 17.

Then, the protrusions 11.12 and the grooves 15.16 are bent in an L-shape and an inverted shape, so that the lid 14 of the battery pack 9 has a gap between the bottom 10 of the main body 1 and the protrusions 11.12. This allows the battery pack 9 to be firmly inserted into the main body 1 without any play.

In addition, when the cut end of the battery pack 9 hits the stopper member 13 of the main body 1 during such a connection and the sliding operation ends, the protrusion 18 elastically deforms the tongue piece 19 as appropriate as shown in FIG. It automatically fits tightly into its recess 20.

Therefore, the battery pack 9 is locked by fitting the convex portion 18 and the concave portion 20 so that it will not easily come off even if it is tilted.

Next, when the battery pack 9 is to be removed for battery replacement, the battery pack 9 is pushed a little forcefully in the opposite direction to that described above.

Then, since the convex part 18 and the concave part 20 are formed relatively smoothly in the battery pack sliding direction due to their circular cross sections, the convex part 18 comes to protrude from the concave part 20 while bending the tongue piece 19 downward. From this point on, the battery pack 9 slides with a light force so that the protrusions 11.12 are successively removed from the grooves 15.16, and thus the battery pack 9 is separated from the main body 1 and removed.

As described above, according to the case connection mechanism with a locking function of the present invention, when two cases such as the battery pack 9 and the main body 1 are connected in a sliding manner, they are automatically locked, so the operation is very easy. In addition, problems such as the battery pack 9 being accidentally removed while the portable radio device is in use are eliminated.

Furthermore, when removing the battery pack, the aforementioned lock is released by pressing the battery pack 9 itself a little forcefully at first, so the operation is easy and the number of parts can be reduced.

The protrusion 11.12 has its end opposite to the stopper member 13 inserted into the opening-side end notch 17 of the groove 15.16, so that its position in the left-right direction is determined, and the upper surface of the battery pack 9 and the bottom of the main body 1 are Since the vertical direction is determined by the contact with the projection 10, it is extremely easy to fit and slide the projection 11.12 and the groove 15.16 in the length direction without any adjustment or manipulation.

Furthermore, since the connection is completed when the stopper member 13 fits into the notch 17, no protrusions or recesses are visible on the outer periphery, which is aesthetically pleasing.
