[0002] As a power source, motors are widely used as power source components in various electronic appliances, mechanical equipment, medical devices, health care products, toys and other products. The existing motor telescopic structure is designed at the front of the motor. In product design, the product length is determined by the motor length plus the telescopic structure length. However, in the design of product structures with length restrictions, this is often impossible because the motor length plus the telescopic structure length is too long, or the overall length of the product is too long to be stored and carried. Summary of the Invention

[0003] The main purpose of the utility model is to provide a motor-driven structural component with linear reciprocating telescopic motion, aiming to utilize the outer side surface of the motor itself as the telescopic length space to minimize the design length of the entire product.

[0004] To achieve the above-mentioned purpose, the present invention provides the following structural component: composed of a motor, a guide sleeve, a structural component, a rotating lever arm and a screw; the motor is installed and fixed in the guide sleeve, the guide sleeve is inserted into the structural component, and the rotating lever arm is sleeved into the structural component and connected to the motor output shaft.

[0005] Wherein, the motor output shaft protrudes and is exposed outside the top of the guide sleeve.

[0006] Wherein, a concave spherical linear guide groove and a convex spherical linear guide rail are provided on the outer cylindrical surface of the guide sleeve facing each other.

[0007] Wherein, a convex spherical linear guide rail and a concave spherical linear guide groove are provided opposite to each other on the inner cylindrical surface of the structural member, the structural member guide rail is sleeved and connected with the guide sleeve guide groove, and the structural member guide groove is sleeved and connected with the guide sleeve guide rail.

[0008] Among them, the inner cylindrical surface of the structural member is provided with a roller coaster track-shaped concave spherical annular closed slide groove with uniform cross-section, the front point of the slide groove is close to the front end surface of the structural member, and the rear point of the slide groove is close to the rear end surface of the structural member. The slide groove divides the guide rail into two parts.

[0009] Wherein, the rotating force arm is provided with a ball head, and the ball head protrudes from the outer cylindrical surface of the guide sleeve and is connected to the concentric sleeve of the structural member sliding groove.

[0010] The rotating arm is provided with a fixing hole, which is connected to the motor output shaft. The rotating arm is further provided with a machine screw hole, which passes through the machine screw hole to fix the rotating arm and the motor output shaft.

[0011] The motor output shaft, the guide sleeve, the structural member, and the rotating arm fixing hole are coaxial after being assembled.

[0012] The beneficial effect of the present invention is as follows: compared with the prior art, the present invention provides a motor-driven structural component with linear reciprocating telescopic motion. After the structural component is sleeved and connected with the guide sleeve, it is restricted by the guide rail and the guide groove and can only move linearly reciprocatingly. The ball head of the rotating lever arm is sleeved in the slide groove of the structural component and is fixedly connected to the motor output shaft, so that the structural component cannot be separated from the guide sleeve and the rotating lever arm. When the motor output shaft rotates, it drives the rotating lever arm to rotate so that the ball head and the adjacent surface of the structural component slide groove generate a force, driving the structural component to reciprocate linearly, and utilizing the length of the outer surface of the motor itself as the telescopic length space of the structural component to realize the reciprocating telescopic motion of the structural component, thereby minimizing the design length of the entire product.

[0023] In order to more clearly illustrate the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0024] See also Figures 1 to 8 The utility model discloses a motor-driven structural component for linear reciprocating telescopic motion, which is used for motor 01 and includes a guide sleeve 02, a rotating arm 03, a structural component 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.

[0025] 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 position 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.

[0026] In this example, a convex spherical linear guide rail 032 and a concave spherical linear guide groove 031 are provided opposite to each other on the inner cylindrical surface 036 of the structural member 03. The guide sleeve 02 is inserted into the structural member 03. The guide rail 032 of the structural member 03 is fitted and connected with the guide groove 021 of the guide sleeve 02. At the same time, the guide groove 031 of the structural member 03 is fitted and connected with the guide rail 022 of the guide sleeve 02. After the fitting connection, the structural member 03 is positioned and restricted by the guide rail 032 and the guide groove 031 and can only move back and forth in a straight line.

[0027] In this example, if 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 033 with a uniform cross-section, the front point 0331 of the slide 033 is close to the front end surface 034 of the structural member 03, and the rear point 0332 of the slide 033 is close to the rear end surface 035 of the structural member 03; the slide 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 machining.

[0028] In this example, after the ball head 041 provided on the rotating lever arm 04 protrudes from the outer cylindrical surface 023 of the guide sleeve 02 and is concentrically 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 material of the rotating lever arm 04 is plastic or metal, and can be produced by 3D printing, mold injection molding or CNC processing.

[0029] 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, it drives the rotating arm 04 to rotate, so that the ball head 041 and the adjacent surface 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 retracted. The horizontal distance between the center of 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.

[0030] The advantages of this utility model are:

[0031] 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.

[0032] The above disclosure is only an optimal specific embodiment of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
