[0014] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0015] See also Figure 1 to Figure 8The present invention provides a design method for linear reciprocating telescopic motion of a motor-driven structural member, comprising a motor 01, a guide sleeve 02, a rotating force arm 03, a structural member 04 and a screw 05; wherein the motor 01 is installed and fixed in the guide sleeve 02, and the output shaft 011 of the motor 01 protrudes and is exposed at the outer top 024 of the guide sleeve 02.

[0016] In this example, the outer cylindrical surface 023 of the guide sleeve 02 is provided with a concave spherical linear guide groove 021 and a convex spherical linear guide rail 022 facing each other. The guide groove 021 and the guide rail 022 are used to locate the extension and contraction direction of the structural member 03 and reduce friction. The guide sleeve 02 is made of plastic or metal and can be produced by 3D printing, mold injection molding or CNC processing.

[0017] In this example, the inner cylindrical surface (036) of the structural member 03 is provided with a convex spherical linear guide rail 032 and a concave spherical linear guide groove 031 facing each other, the guide sleeve 02 is inserted into the structural member 03, the guide rail 032 of the structural member 03 is sleeved and connected with the guide groove 021 of the guide sleeve 02, and at the same time, the guide groove 031 of the structural member 03 is sleeved and connected with the guide rail 022 of the guide sleeve 02. After the sleeved connection, the structural member 03 is positioned and restricted by the guide rail 032 and the guide groove 031 so that it can only move in a straight line.

[0018] In this example, Figure 6 Figure 7 Figure 8 As shown, the inner cylindrical surface (036) of the structural member 03 is provided with a roller coaster track-shaped concave spherical annular closed slide groove 033 with uniform cross-section, the front point 0331 of the slide groove 033 is close to the front end surface 034 of the structural member 03, and the rear point 0332 of the slide groove 033 is close to the rear end surface 035 of the structural member 03; the slide groove 033 divides the guide rail 032 into two parts, the guide rail 0321 and the guide rail 0322, and the guide rail 032 is divided into two parts without affecting the positioning and linear reciprocating motion of the structural member 03; the material of the structural member 03 is plastic or metal, and can be produced by 3D printing, mold injection molding or CNC processing.

[0019] In this example, after the ball head 041 provided on the rotating lever arm 04 protrudes from the outer circle 023 of the guide sleeve 02 and is cocentrically fitted with the slide groove 033 of the structural member 03, the fixing hole 042 provided on the rotating lever arm 04 is connected to the output shaft 011 of the motor 01, and the machine screw 05 is passed through the machine screw hole 043 provided on the rotating lever arm 04 to fix the rotating lever arm 04 and the output shaft 011 of the motor 01; the rotating lever arm 04 is made of plastic or metal and can be produced by 3D printing, mold injection molding or CNC machining.

[0020] In this example, the output shaft 011 of the motor 01, the guide sleeve 02, the structural member 03, and the fixing hole 042 of the rotating arm 04 are coaxial after being assembled; the ball head 041 of the rotating arm 04 is sleeved in the slide groove 033 of the structural member 03, so that the structural member 03 cannot be separated from the guide sleeve 02 and the rotating arm 04. When the output shaft 011 of the motor 01 rotates, the rotating arm 04 is driven to rotate so that the ball head 041 and the adjacent surfaces of the slide groove 033 of the structural member 03 generate a force, driving the structural member 03 to reciprocate and telescopic motion in a straight line; Figure 4 Figure 5 As shown, when the ball head 041 of the rotating arm 04 rotates to coincide with the center of the rear point 0332 of the slide groove 033 of the structural member 03, it is the maximum extension of the structural member 03. When the ball head 041 of the rotating arm 04 rotates to coincide with the center of the front point 0331 of the slide groove 033 of the structural member 03, the structural member 03 is completely contracted. The center horizontal distance between the front point 0331 of the slide groove 033 of the structural member 03 and the rear point 0332 is the maximum stroke of the reciprocating telescopic motion. The maximum stroke of the reciprocating telescopic motion of the structural member 03 can be adjusted by moving the rear point 0332 forward or backward. The structural member 03 completes one linear reciprocating telescopic motion every time the rotating arm 04 rotates one circle.

[0021] The advantages of the present invention are: The length of the outer side surface of the motor 01 itself is used as the telescopic length space to realize the linear reciprocating telescopic motion of the structural member 03, thereby minimizing the design length of the entire product.

[0022] The above disclosure is only an optimal specific embodiment of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
