Electric accessory case equipped with a clutch mechanism

Abstract

To provide an electric small item case which can be easily operated with one hand, can be smoothly opened and closed with one touch, and has a structure that is not easily broken by impact or overload. [Solution] A clutch mechanism is formed by connecting a driven bevel gear 7, which transmits 90-degree rotation via a drive bevel gear 6 driven by a servo motor 4, to a small item storage section via a spring, allowing opening and closing with one hand, and the shock-absorbing structure effectively prevents damage to the mechanism.

Description

[Technical Field]

[0001] This invention relates to a small item storage case, and more particularly to an electric small item storage case that uses a clutch mechanism to connect a bevel gear driven by a servo motor to a small item storage section with a spring, thereby absorbing external impacts and preventing damage to the mechanism. [Background technology]

[0002] There are many portable cases for storing small items, and most of them have a structure where the lid is opened and closed manually. For example, gum cases, pill cases, and business card cases generally have a manual opening and closing mechanism, such as a slide or button. While these manual cases have a simple structure and are easy to manufacture, they often require the use of both hands to operate, which can be inconvenient depending on the situation. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventional small item storage cases such as gum cases and pill cases generally have a structure where the lid is opened and closed manually, requiring both hands to be used. This makes it difficult to take out the contents while walking, driving, or in situations where one hand is occupied, and does not ensure sufficient convenience. Furthermore, simply making it electric also poses the problem that the mechanism is prone to damage if excessive load is placed on the moving parts, making it less durable for repeated use as a portable gadget. Therefore, there is a demand for a small, highly practical storage case that can be easily operated with one hand, can be opened and closed smoothly with a single touch, and has a structure that is resistant to shocks and overloads. [Means for solving the problem]

[0004] To solve the above problems, the electric accessory case of the present invention is equipped with a servo motor driven by a battery of about 5V, and the rotational motion is converted by 90 degrees by a driving bevel gear connected to the servo motor, and the accessory storage section is opened and closed via a driven bevel gear. Furthermore, a spring is placed between the driven bevel gear and the small item storage section, providing flexibility in the transmission of rotation and forming a clutch mechanism that releases force even when external impact or overload is applied. This configuration not only allows for easy one-handed opening and closing with one touch, but also reduces wear from repeated use and damage to the mechanism due to external impacts, increasing the reliability and practicality of the gadget. [Effects of the Invention]

[0005] According to this device, the opening and closing of the storage case can be done electrically, making it easier to operate with one hand than conventional manual cases, and allowing for quick removal of contents with a single touch. This allows for comfortable use even when only one hand is available, such as while walking or working, and greatly improves user convenience. Furthermore, by using a bevel gear for rotation conversion in the drive section and equipping it with a clutch mechanism that uses a spring, damage and wear to the structure can be effectively prevented even when external impacts or loads greater than expected are applied. As a result, it is possible to realize an electric storage case that is sufficiently durable and reliable even when used as a portable gadget that is carried around daily and used repeatedly.

DETAILED DESCRIPTION OF THE INVENTION

[0007] The electric accessory case of the present invention is configured with an accessory storage section, a drive section, and a battery storage section inside the housing. The drive unit is equipped with a small servo motor that operates at a voltage of about 5V, and a drive-side bevel gear is fixed to the output shaft of the servo motor. This bevel gear meshes with a driven bevel gear arranged in a perpendicular direction, converting the rotational motion by approximately 90 degrees and transmitting it. The bevel gear on the driven side is connected to a small item storage compartment, and a spring is inserted between them, giving flexibility to the rotation transmission and functioning as a clutch mechanism that releases force when external impact or overload is applied. [Example]

[0008] An embodiment will now be described with reference to the accompanying drawings. Reference numerals 1 and 2 denote a cover and a main body of an electric accessory case, each made of a suitable material such as ABS resin. Reference numeral 3 denotes a battery compartment capable of housing batteries such as AAA batteries. Reference numeral 4 denotes a small servo motor, such as an SG90, with a drive bevel gear 6 attached to the output shaft of the servo motor. The rotation of the driving bevel gear 6 is changed in direction by 90 degrees via the driven bevel gear 7 , and the small item storage section 5 is connected to the driven bevel gear 7 via a spring 8 . The operation of the servo motor 4 causes the small item storage section 5 to open and close.

[0009] The servo motor 4 is driven at a predetermined angle by an appropriately provided control means. Although details of the control circuit are omitted, it can be controlled by a general microcomputer or the like.

[0010] Even if the small item storage compartment 5 comes into contact with an obstacle during opening or closing and is prevented from opening or closing, the driven bevel gear 7 rotates freely and the spring 8 expands and contracts, absorbing the stress and preventing excessive stress from concentrating on the mechanism, preventing damage and early wear of the components. This ensures high reliability that can withstand repeated use. [Industrial Applicability]

[0011] The electric accessory case of the present invention can be used to store gum, pills, tablets, business cards, etc., and is particularly useful in situations where one-handed operation and quick removal of contents are required. Specifically, it is expected to be used in a wide range of applications, such as a medication aid in the medical and nursing care fields, a card storage case in business situations, and a portable container for sweets and soft drinks in everyday life.

Claims

[Claim 1] This electric accessory case is characterized by having a clutch mechanism formed between the driven bevel gear and the accessory storage section by connecting the driven bevel gear, whose rotational motion is converted by 90 degrees by a battery of about 5V and a drive bevel gear connected to a servo motor driven by the battery, and the accessory storage section with a spring.
