Abstract:
A system is provided for generating electrical energy from passage of a vehicle over a road surface. The system comprises a pressure receiver connected to a rotatable shaft associated with a primary transmission unit. The pressure receiver is adapted for swinging motion over the road surface, so that upon pressure being applied to the pressure receiver by the moving vehicle the receiver swings in the direction of vehicle movement, wherein kinetic energy of vehicle motion is transferred to the shaft resulted in its rotation causing operation of a primary energy transmission unit consisting of the driving sprocket and a driven sprocket-follower wheel assembly which is coupled by a leading transmission arrangement an electrical generator.
Abstract:
A slider-crank mechanism includes a slider, a shaft, and a drive train correlating reciprocation of the slider with continuous rotation of the shaft. The slider reciprocates along a slider axis with respect to a slider surface. The drive train includes a linear actuator connected to the slider for substantially pure collinear movement with the slider to substantially eliminate side forces between the slider and slider surface. The slider and drive train may include a rack-and-pinion configuration. The rack-and-pinion may drive or be driven by a Grashofian four-bar crank-rocker linkage that includes a rocker arm, floating link, web, and the shaft. The slider-crank mechanism may be employed in a power generation system such as an internal combustion engine or a power consuming system such as a compressor or pump.
Abstract:
The wiper device includes a first pivot shaft, a first swing lever, a second pivot shaft, a second swing lever, a link rod, a crank arm, and a drive rod. The first swing lever extends from the first pivot shaft in a radial direction of the first pivot shaft. The second swing lever extends from the second pivot shaft in a radial direction of the second pivot shaft. The link rod has a first end connected to a tip part of the first swing lever and a second end connected to a tip part of the second swing lever. The crank arm extends from an output shaft of a motor in a radial direction of this output shaft. The drive rod has a first end connected to a tip part of the crank arm and a second end connected to an intermediate part of the link rod.
Abstract:
An electrically driven device includes a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft having a second rotary axis and mounted in the housing for performing a pivoting about the second rotary axis. The driven shaft is coupled to the drive shaft by a gear mechanism including a scotch yoke mechanism converting a rotary motion of the drive shaft into a reciprocating motion of the driven shaft. The scotch yoke mechanism includes a cross slider having a sliding support extending perpendicular to the first rotary axis and receiving the drive pin either directly or through a sliding block with a bearing receiving the drive pin. The cross slider is guided in the housing by at least two pivotable links. The driven shaft is coupled to the cross slider by an arm, converting a rotary motion of the drive shaft into a reciprocating of the driven shaft.
Abstract:
A panel opening/closing device includes: a support which supports a panel and is turnable about a first rotary shaft; a dial which is turnable about a second rotary shaft in accordance with an operation by a user; and a movable unit which undergoes horizontal movement and includes pins inserted into a groove of the dial and a groove of the support, respectively.
Abstract:
A power door opening device comprises a casing; a motor mounted to the casing; a planetary gear unit housed in the casing to reduce rotation speed of the motor; and an output mechanism that transmits reduced rotation from the planetary gear unit to a door to open and close the door. The planetary gear unit comprises a sun gear that rotates with a rotary shaft of the motor; a planetary carrier fixed in the casing; a planetary gear that is rotatably supported to the planetary carrier and meshes with the sun gear; and a ring gear that is rotatably supported in the casing and meshes with the planetary gear. Both ends of the sun gear are supported.
Abstract:
A door opening/closing device includes: a motor; and an output shaft arranged on a line extending from an axial center of the motor, power of the motor being transmitted to the output shaft via a deceleration mechanism, the door opening/closing device opening and closing a door via the output shaft by driving the motor. Positional deviation on both end surfaces of the output shaft is set to equal to or higher than φ0.01 and equal to or lower than φ0.1.
Abstract:
In the transmission of mechanical movements, a mechanical angular positioning device is provided, and applies notably to optical instruments necessary to position an element such as a mirror according to three predefined positions. The angular positioning device comprises an assembly of connecting rods and an assembly of pivot connections, the axes of which are parallel to one another. A first input connecting rod, a second output connecting rod and a third connecting rod are in pivot connection with a frame of the device. A fourth and a fifth connecting rod are each connected by two pivot connections to two other connecting rods. The input connecting rod can be rotated by a motor. The angular positioning device is configured such that the output connecting rod can adopt three distinct angular positions, for each of which two connecting rods in pivot connection with one another generate a dead center in the device.
Abstract:
A device for moving one or more vehicle-mounted objects and a vehicle having the same are provided. The device comprises: a housing; a cover; at least one pivot for adjusting the cover, the at least one pivot disposed in the housing and comprises a first end and a second end, wherein the first end of the at least one pivot is coupled with the cover; and a box assembly disposed in the housing, the box assembly being movable between a first position away from the opening and a second position near the opening. The box assembly is coupled with the second end of the at least one pivot, wherein the cover exposes at least a part of the opening when the box assembly is at the second position, and wherein the cover covers at least a part of the opening when the box assembly is at the first position.
