DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1-Figure 4 As shown, a single-motor drive structure that can be used for lifting and rotating an object includes a base 1, a rotating base 2 is rotatably arranged on the base 1, a rotating platform 3 is arranged on the rotating base 2, and the rotating platform 3 is mounted on the rotating base 2 through a lifting component 4; a motor 5 is arranged below the base 1, and its output shaft 6 passes through the base 1 and cooperates with the rotating base 2 and the lifting component 4; the power gear 7 on the output shaft 6 is engaged with the rotating gear 21 of the rotating base 2 to drive the rotation of the rotating base 2 and the rotation of the rotating platform 3; the power gear 7 on the output shaft 6 is engaged with the lifting rack 49 of the lifting component 4 to drive the lifting of the lifting component 4, thereby driving the lifting of the rotating platform 3.

[0027] In this embodiment, an upper fixing frame 61 and a lower fixing frame 62 are arranged on the output shaft 6 at intervals. The upper fixing frame 61 and the lower fixing frame 62 have the same structure, and include a plurality of L-shaped frames evenly spaced in the circumferential direction. Figure 5As shown, in order to facilitate the installation and removal of the power gear 7 on the upper fixing frame 61 and the lower fixing frame 62, a central hole 73 is provided in the middle of the power gear 7, and a plurality of through holes 71 and mounting grooves 72 corresponding to the L-shaped frame are provided around the central hole 73. The through holes 71 and the mounting grooves 72 are arranged crosswise, the central hole 73 is used for the output shaft 6 to be inserted, the through hole 71 is used for taking the power gear 7 on the output shaft 6, and the mounting grooves 72 are used for the installation and clamping of the power gear 7 on the output shaft 6. The lower fixing frame 62 is placed at the same height as the rotating gear 21, and the upper fixing frame 61 is placed at the same height as the lifting rack 49.

[0028] It can be understood that by switching the position of the power gear 7 on the upper fixed frame 61 or the lower fixed frame 62, the corresponding rotating gear 21 or the lifting rack 49 is driven to engage, and the rotating gear 21 or the lifting rack 49 further drives the corresponding structural parts to realize the rotation and lifting operation of the rotating platform.

[0029] In this embodiment, a plurality of small rollers 23 are arranged at the bottom of the rotating seat 2, and the small rollers 23 are in rolling cooperation with the upper end surface of the base 1; the small rollers 23 can also be designed as other structures, which are used to support the rotating seat 2 and facilitate the rotation of the rotating seat 2. A rotating gear 21 is arranged in the middle of the rotating seat 2, and an arc groove 21 is arranged around the rotating gear 21. The output shaft 6 is passed through the arc groove 22 and drives the rotating seat 2 to rotate along the arc groove 22. It can be seen that when the power gear 7 is installed on the lower fixed frame 62, the power gear 7 is meshed with the rotating gear 21, and the motor 5 drives the power gear 7 to mesh with the rotating gear 21, thereby driving the rotation of the rotating seat 2 and the rotating platform 3 on the rotating seat 2; because the power gear 7 is not meshed with the lifting rack 49 at this time, the lifting assembly 4 and the rotating platform 3 do not perform lifting operations.

[0030] As can be seen from the figure, the lifting assembly 4 includes symmetrically arranged X-shaped scissor frames 41, the intersection of two groups of X-shaped scissor frames 41 is connected by a rotating shaft 43, and the X-shaped scissor frames 41 include two brackets that are cross-hinged and linked by the rotating shaft 43. Each corresponding end of the two groups of X-shaped scissor frames 41 is connected by a connecting rod 42; among the two upper connecting rods 42, one connecting rod 42 is hingedly matched with the lower end surface of the rotating platform 3 through the upper fixed blocks 44 arranged at both ends, and the other connecting rod 42 is rollingly matched with the lower end surface of the rotating platform 3 through the upper rollers 45 arranged at both ends; the two lower connecting rods 42 are symmetrically arranged with the two upper connecting rods 42, one connecting rod 42 is hingedly matched with the upper end surface of the rotating seat 2 through the lower fixed blocks 46 arranged at both ends, and the other connecting rod 42 is rollingly matched with the upper end surface of the rotating seat 2 through the lower rollers 47 arranged at both ends. The lifting rack 49 is mounted on the two lower connecting rods 42. One end of the lifting rack 49 is fixedly connected to the connecting rod 42 provided with the lower roller 47 through the connecting plate 48, and the other end is movably matched with the connecting rod 42 provided with the lower fixing block 46. In this embodiment, the connecting plate 48 is provided with a mounting hole for inserting and installing the connecting rod 42. The engagement of the lifting rack 49 with the power gear 7 drives the distance between the connecting rod 42 provided with the lower roller 47 and the connecting rod 42 provided with the lower fixing block 46 to change, thereby driving the angle change of the X-shaped scissor frame 41 to realize the lifting and lowering of the rotating platform 3.

[0031] It can be seen that when the power gear 7 is installed on the upper fixed frame 61, the power gear 7 is meshed with the lifting rack 49, and the motor 5 drives the power gear 7 to mesh with the lifting rack 49, thereby raising and lowering the X-shaped scissors frame 41 and the rotating platform 3; since the power gear 7 is not meshed with the rotating gear 21 at this time, the rotating seat 2 and the rotating platform 3 do not perform a rotating operation.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
