Abstract

[Purpose of the article] This invention is an "electric actuator" that can cause a machine to move linearly relative to a cylinder body under the rotational drive of a motor (not shown). The electric actuator comprises: a roughly rectangular cylinder body; a roughly rectangular motor portion connected to the cylinder body at one end of the cylinder body (the right side of the front view) and accommodating the motor; a shaft disposed on the cylinder body in a retractable manner at the other end of the cylinder body (the left side of the front view); and a machine having the other end connected to the end of the shaft via a connecting plate (see reference figures (1) to (3) etc.). The connecting plate is formed in a square shape on the first side (viewed from the left side view) and has no lower left corner and lower right corner. In addition, the machine is roughly rectangular, and two first recesses extending parallel to the shaft are provided on the second side (the upper side in the front view). On the third side (the right side in the front view) and the fourth side (the left side in the front view) located on the opposite side of the third side, a plurality of second recesses extending parallel to the shaft are formed in the cylinder body, and a third recess is formed in the motor part (refer to reference figures (1) to (3), etc.). The motor housed in the motor part is connected to the shaft via a mechanical transmission system (feed screw shaft, feed screw nut, etc.) not shown in the figure. When in use, for example, when the object to be displaced is fixed to the machine, if the motor is driven to rotate, the machine and the object to be displaced will be displaced linearly through the shaft and the connecting plate. ;【Features of the creation】;This creation is related to the appearance design of an "electric actuator". As shown in the three-dimensional diagram and reference figures (1) to (3), the main body of this creation is a special shape composed of a long rectangular cylinder body with a machine that can slide and displace at the top and a retracted long rectangular motor part located on the right. The front and rear surfaces of the above-mentioned cylinder body have a wide band-shaped concave surface and a second concave portion with a groove shape below the concave surface, and the front and rear surfaces of the machine above the above-mentioned concave surface form a thin groove. The top surface of the machine of the cylinder body is formed into a plurality of band-shaped first concave parts, and the lower left side of the machine is formed into a nearly trapezoidal connecting plate with inclined and missing corners at the front and rear lower corners. As shown in the right side view, the lower part of the motor part is formed into a trapezoid with inclined and missing corners at the front and rear lower corners, and the upper part is also formed into a larger trapezoid. The front and rear surfaces between the upper and lower trapezoids form a protruding third concave part. Reference Figures (1) to (2) show the three-dimensional state of the machine and the axis displacement and another three-dimensional state of reference Figure (2). Reference Figure (3) shows the three-dimensional state of the machine removed. The above reference figures all show the description of each component of this creation. The roughly horizontal parallel thin lines, roughly vertical parallel thin lines, roughly inclined parallel thin lines and roughly circular thin lines shown on the surface of each figure are all shadow lines showing the shape of the three-dimensional surface. The above constitutes the overall shape of this creation, which is exquisite and unique, with novel and unique visual effects and creativity.
