Linear actuator system
10256695 · 2019-04-09 · ·

A linear actuator system comprising a linear actuator having a housing and an outer tube, which with a rear end is secured to a side of the housing at a front end thereof. The outer tube surrounds an electric motor driven spindle unit and an activation element. The linear actuator system further comprises a control box having a control, where the control box is arranged in the angle between the housing and the outer tube on the linear actuator. The control box is fastened with a mounting bracket to the outer tube on the linear actuator. The mounting bracket comprises a tubular portion, whereby it can be pushed in over the outer tube and the mounting bracket and the control box are also designed with interacting fastening means for fastening the control box to the mounting bracket. The tubular portion of the mounting bracket has an axially extending slit and the interacting fastening means between the mounting bracket and the control box are constituted on both sides of the slit. The interacting fastening means are designed such that when the control box is fastened onto the mounting bracket, the slit contracts so that the tubular portion of the mounting bracket tightens around the outer tube on the linear actuator. The construction is characterized in that the control box is only fastened to the mounting bracket on the outer tube of the linear actuator. This simplifies the fastening quite considerably while simultaneously simplifying the design.

Actuator for generating vibration

A remote controlled vibration imparting device for a concrete finishing tool uses a housing having a chamber surrounded by an inner surface of the housing. A vibrator with a support, a rotor with a shaft and weighted body, a motor, and a resilient link between the shaft and the motor is positioned within the housing chamber. The vibrator also includes a resilient band to separate the vibrator from the housing inner surface. First and second adaptors are employed for the housing to be placed between the handle and the terminus of a concrete finishing tool.

Powered Crowbar

A device for removing materials secured to surfaces. The powered crowbar includes a shaft having a first end and a second end, wherein the first end tapers to a flat chisel, such that the chisel is designed to fit within tight spaces. The second end includes a housing and grip, wherein the grip is designed to be held by a user. The housing has a motor, a power source operably connected to the motor, a control module operably connected to the motor, and an activation switch operably connected to the motor. The motor is designed to vibrate the shaft and chisel. In this way, the powered crowbar efficiently loosens and removes materials, such as a nailed board, secured to a surface.

VIBRATION MOTOR

A vibration motor is provided. The vibration motor comprises: a rotor shaft; a first magnet and a second magnet arranged on the rotor shaft so as to face each other; a circuit board having a hollow hole through which the rotor shaft passes and coils arranged thereon, the coils respectively facing the first and second magnets; a housing forming an inner space in which the rotor shaft and the circuit board are mounted; a shaft passing through the rotor shaft and fixedly erected in the housing; a first yoke and a second yoke on which the first and second magnets are respectively installed and which are fixedly coupled to the rotor shaft so as to integrally rotate along with the rotor shaft; a weight installed on the first yoke or the second yoke; and a bearing portion comprising a plurality of bearings coaxially arranged with the shaft.

Efficient haptic actuator

An actuator includes a housing, a moving element and two springs connected between the housing and the moving element such that one of the two springs crosses the other of the two rotor springs without contacting the other of the two springs. A drive component causes the moving element to move.

Vibration Motor

A motor case of a vibration motor has a first tubular part and a first inward flange integrally formed in a flange shape in the inward direction from the upper opening end of the first tubular part. A rotary shaft 30 is supported in an upper oil-impregnated bearing and a lower oil-impregnated bearing, and an upper portion of the rotary shaft protrudes from the motor case. The rotary shaft is inserted into a soft washer, with the soft washer between the rotor unit and the upper oil-impregnated bearing. A weight is eccentrically fixed to the upper portion of the rotary shaft, and an attraction magnet is fixed to the motor case and attracts the weight toward the motor case side. A retainer, which prevents the upper oil-impregnated bearing from coming out in the upward direction, is formed on the motor case.

EFFICIENT HAPTIC ACCUATOR

The current document is directed to non-linear haptic actuators that use a rotor, rotor-suspension, and spring subsystem to efficiently generate vibrational forces in various types of devices and appliances in which the non-linear haptic actuators are incorporated. Non-linear haptic actuators can be designed and manufactured to be more space efficient than unbalanced-electric-motor and linear-resonant vibration modules and, because most of the frictional forces produced in unbalanced-electric-motor and linear-resonant vibration modules are eliminated from non-linear haptic actuators, non-linear haptic actuators are generally more power efficient and robust than unbalanced-electric-motor and linear-resonant vibration modules.

REMOTE DRIVE AND WEARABLE ADULT DEVICES
20180289585 · 2018-10-11 ·

The majority of adult devices have been designed for an individual to hold. However, it would be beneficial to provide users with a range of adult devices that support their use either in a hands free manner and/or are compatible with being worn by the user for varying periods of time from intermittent/occasional short durations through to extended wearing such as all day for example. In order to provide such wearable devices being able to separate the drive means from the stimulation means provides increased design flexibility as well as allowing different designs of adult device to be implemented as the design flexibility within the appropriate regions of the user's anatomy increases when the large vibratory motors are removed and connected to the stimulation means via flexible drive shaft. Further, beneficially, flexible drive shafts allow operation as the user moves during normal activities, such as sitting, standing, walking, etc.
