JP-2026075215-A - Storage case structure with electric unlocking and key cylinder unlocking

Abstract

[Problem] To provide a storage case that can be unlocked in an emergency by inserting a key into a key cylinder lock, and normally unlocked using BLE communication via a smartphone. [Solution] The present invention relates to an electrically unlockable key cylinder lock type storage case in which an emergency unlocking mechanism is installed inside the storage case lid, a latch board module assembly with a built-in BLE communication board is mounted inside the storage case lid, a motor is driven by BLE communication, a worm gear integrated with the motor shaft rotates a worm wheel, an operating wire fitted into the circumferential groove of the worm wheel is activated, electrically releasing the lock block from preventing the release lever from rotating, and allowing the release lever to rotate counterclockwise by the knob, thereby moving the latch in the unlocking direction and opening the storage case lid.

Claims (4)

1. This is an electrically unlockable key cylinder lock type storage case in which a latch board module housing case with a built-in BLE communication board is installed inside the lid of the storage case. Normally, the motor is driven by BLE communication, and a worm gear integrated with the motor shaft rotates the worm wheel. An operating wire fitted into the groove on the circumferential surface of the worm wheel moves, electrically releasing the lock block that prevents the release lever from rotating. This allows the release lever to rotate counterclockwise via the knob, moving the latch in the unlocking direction and opening the lid of the storage case. The key cylinder lock type storage case is characterized by its ability to achieve both electric and emergency unlocking; in an emergency, an emergency release key is inserted into the cylinder lock and rotated 90 degrees clockwise, causing the emergency release lock plate to detach from the latch and open the lid.
2. The storage case described in claim 1 is characterized in that, even if excessive torque is applied to the knob, a release lever rotation spring is set so that the spring twists, preventing the transmission of excessive torque to the release lever or latch.
3. The storage case described in claim 1 is characterized in that, although excessive load is easily applied to the latch when opening and closing the storage case lid or when attempting to open it intentionally, the latch cases A and B of the latch case assembly can be made of inexpensive resin by setting a reinforcing plate.
4. A storage case as described in claim 1, characterized in that the cam shape for the lid opening/closing confirmation switch allows for operation with a single lid opening/closing confirmation switch, whether during electric unlocking or emergency unlocking.

Description

This invention relates to a locking mechanism for a storage case, where the existing storage case uses a cylinder lock type mechanism where inserting a matching key rotates a locking lever to open the lid. However, this mechanism is intended for emergency use only. Normally, the lock is unlocked and the lid opened via a motor driven by external communication. In the conventional structure, the storage case 1 consists of a storage case body 1a and a storage case lid 1b (Figure 1). By inserting the key 2a and turning it clockwise (Figure 2), the lock plate 2b detaches from the storage case body flange 3 (Figure 3), and the storage case lid 1b opens (Figure 4). Figure 1 is an external view of the storage case 1 body; the left figure shows the case before key insertion, and the right figure shows the case after key insertion. Figures 2 and 3 are cross-sections of the storage case 1 shown in Figure 1 along the dashed-dot line.
