Description

Technical field The present invention relates to a hand-held mechanical drive device with interchangeable functional modules. The device serves as a modular platform in which a mechanical drive located in the handle housing generates movements that can be transferred to various interchangeable functional modules in the areas of cleaning, household, care and gardening. State of the art Handheld devices with a vibration function are known, for example, as massage devices or electric toothbrushes. However, these devices usually have fixed, defined function heads and are therefore limited to a single application. Although modular systems are known, they often lack an efficient and adaptable transmission of mechanical movements between a drive and different functional modules. In particular, the adaptation of the transmitted motion to different applications is inadequately resolved. Object of the invention The invention is based on the objective of providing a hand-held device that is versatile and enables efficient and adaptable transmission of mechanical movements to different interchangeable functional modules. Description of the invention The task is solved by a hand-held, motor-driven device comprising: • a handle housing (2), • a power source (3) arranged in the handle housing (2), in particular a battery, • a control unit (4), • a drive motor (6), • and a mechanical interface (8) for detachable connection with a functional module (9). The interface (8) is designed to transmit a mechanical movement generated by the drive motor (6), in particular a vibrating, oscillating and / or swinging movement, to the functional module (9). According to the invention, the interface (8) comprises an elastic coupling element, in particular a resonating body in the form of a rubber ring, for influencing the vibration transmission. The interface (8) can be designed in particular as: • bayonet fitting, • threaded connection, • plug connection, • snap connection or • magnetic connection. Optionally, the interface (8) can include electrical contacts for power and / or signal transmission. steering The device is controlled by a control unit (4) which is designed to regulate the speed and / or vibration intensity of the drive motor (6). The control unit (4) may in particular comprise an electronic control unit and be designed to implement pulse width modulation (PWM) and / or speed control. For operating the control unit, an operating element (5), in particular a push button, may be provided. Additionally or alternatively, a manually operated rotary control (1), in particular in the form of a potentiometer, may be provided for stepless adjustment of the speed and / or vibration intensity. Energy supply The device is preferably powered by an energy source (3) arranged in the handle housing (2), in particular a rechargeable battery, preferably a lithium-ion battery. In one embodiment, the device can additionally have a power output through which electrical energy can be supplied to external consumers. Technical effect and advantages of the invention The use of an elastic coupling element in the interface allows for targeted control of the mechanical vibrations generated by the drive. This allows for adaptation to different functional modules, thereby achieving both damping and amplification of the transmitted movement. This leads to improved efficiency, increased ease of use, and expanded usability of the device. In particular, the modular interface in combination with the elastic coupling element enables the universal use of a single drive unit for different applications.
