Description

Technical Field

[0001] This utility model belongs to the field of robot drive technology, specifically relating to a robot drive mechanism. Background Technology

[0002] Robots are automated machines that perform tasks. They can be controlled by humans, run pre-programmed routines, or act according to principles established by artificial intelligence. Their purpose is to assist or replace humans in jobs such as manufacturing, construction, service industries, or hazardous work. Robots used in the service industry require cameras to collect information from their surroundings.

[0003] Traditional robotic camera adjustment methods often suffer from complex operation, limited adjustment range, and difficulty in meeting diverse and complex shooting or monitoring needs. Furthermore, their overall structure employs a relatively decentralized connection configuration, lacking a compact, integrated installation. Utility Model Content

[0004] The purpose of this invention is to provide a drive mechanism for a robot to solve the problems of flexible shooting and compact installation in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drive mechanism for a robot includes a base plate, bearing blocks symmetrically mounted on the top of the base plate, a joint assembly movably connected to the bearing blocks, a driven shaft mounted on the top of the joint assembly, a loading tray at the top of the driven shaft, and a camera mounted on the surface of the loading tray; a drive assembly for driving the driven shaft to rotate is installed inside the joint assembly; and a transmission component for adjusting the tilt angle of the joint assembly is mounted on the surface of the base plate.

[0007] Furthermore, the combined component includes a central column with positioning ears at both ends, the positioning ears being rotatably connected to the bearing block, a through hole being formed inside the central column, a positioning shaft being provided above the central column, a positioning hole being formed inside the positioning shaft, and the driven shaft being rotatably connected to the positioning hole.

[0008] Furthermore, a semi-toothed disc is fixed to the bottom of the central column. The transmission component includes a second motor, which is mounted on the surface of the base plate. The output end of the second motor is connected to an output tooth, which meshes with the semi-toothed disc.

[0009] Furthermore, a driven tooth is installed at the bottom of the driven shaft, and the drive assembly includes a sealing disc and a first motor. The sealing disc is installed at both ends of the central column, and the first motor is installed on the sealing disc. The output end of the first motor is connected to an output shaft, and a driving tooth is installed on the output shaft. The driving tooth meshes with the driven tooth.

[0010] Furthermore, the output shaft and driven shaft extend into the through hole. By placing the output shaft and driven shaft within the through hole, the drive assembly can be concealed, resulting in a simpler and more aesthetically pleasing overall structure. This enhances the product's appearance and improves the user's visual experience. Simultaneously, it provides a relatively enclosed environment for the drive assembly, effectively isolating it from external factors such as dust and moisture. This protective measure extends the lifespan of the drive components and reduces malfunctions and maintenance costs caused by environmental factors.

[0011] Furthermore, the first motor is installed within the through hole, and the surface of the sealing disc is provided with a heat dissipation mesh groove. Installing the first motor within the through hole of the central column avoids exposing the motor, further extending the equipment's lifespan. Simultaneously, the internal first motor dissipates heat through the heat dissipation mesh groove, without affecting its operation.

[0012] The technical solution of this utility model has the following beneficial effects:

[0013] 1. By using integrated components and adopting a unified orientation adjustment, camera adjustments are centralized within these components, improving overall linkage and compactness. The rotational connection between the positioning ear and the bearing block allows for adjustment to the optimal tilt angle as needed, thus meeting the shooting or monitoring requirements in different scenarios. The cooperation between the driven shaft and the positioning hole enables the camera to adjust not only the tilt angle vertically but also to change the shooting direction horizontally, achieving omnidirectional and multi-angle shooting flexibility.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] Example 1:

[0023] refer to Figures 1-4 A drive mechanism for a robot includes a base plate 10, bearing blocks 11 symmetrically mounted on the top of the base plate 10, a joint assembly 20 movably connected to the bearing blocks 11, a driven shaft 30 mounted on the top of the joint assembly 20, a loading tray 31 provided on the top of the driven shaft 30, and a camera 40 mounted on the surface of the loading tray 31.

[0024] The combined assembly 20 includes a central column 201, with positioning ears 203 at both ends of the central column 201. The positioning ears 203 are rotatably connected to the bearing block 11. A through hole 202 is opened in the central column 201. A positioning shaft 204 is provided above the central column 201. A positioning hole 205 is opened in the positioning shaft 204. The driven shaft 30 is rotatably connected in the positioning hole 205.

[0025] In the above scheme, the joint component 20 is rotatably connected to the bearing block 11 via the positioning ear 203, so that the tilt angle of the central column 201 can be adjusted. The driven shaft 30 is installed in the positioning hole 205, that is, the driven shaft 30 can follow the tilt angle adjustment of the central column 201, thereby changing the tilt angle of the camera 40 on the tray 31. At the same time, the driven shaft 30 is rotatably connected in the positioning hole 205, and the rotation changes the angle of the driven shaft 30, thereby changing the shooting direction of the camera 40.

[0026] In summary, by using the joint component 20 and adopting an integrated orientation adjustment, the adjustment of the camera 40 is centralized in the joint component 20, improving overall linkage. The rotational connection between the positioning ear 203 and the bearing block 11 allows adjustment to the optimal tilt angle according to actual needs, thereby meeting the shooting or monitoring requirements in different scenarios. The cooperation between the driven shaft 30 and the positioning hole 205 enables the camera 40 to not only adjust the tilt angle in the vertical direction, but also change the shooting direction in the horizontal direction, achieving all-round, multi-angle shooting flexibility.

[0027] Further reference Figure 1 and Figure 2 The base plate 10 is equipped with a transmission component for adjusting the tilt angle of the combined assembly 20. A semi-toothed disc 36 is fixed to the bottom of the central column 201. The transmission component includes a second motor 37, which is mounted on the surface of the base plate 10. The output end of the second motor 37 is connected to an output tooth 38, which meshes with the semi-toothed disc 36.

[0028] In a further implementation, by controlling the start of the second motor 37, the tilt angle of the central column 201 is adjusted under the meshing of the output tooth 38 and the half-tooth disk 36.

[0029] refer to Figure 1 and Figure 2 The combined assembly 20 contains a drive assembly for driving the driven shaft 30 to rotate; a driven gear 32 is mounted on the bottom of the driven shaft 30. The drive assembly includes a sealing disc 33 and a first motor 34. The sealing disc 33 is mounted at both ends of the central column 201, and the first motor 34 is mounted on the sealing disc 33. The output end of the first motor 34 is connected to an output shaft 35, and a driving gear 351 is mounted on the output shaft 35. The driving gear 351 meshes with the driven gear 32.

[0030] In the above scheme, by starting the first motor 34, the driven shaft 30 can be automatically driven to rotate under the meshing of the active gear 351 and the driven gear 32, thereby changing the shooting direction of the camera 40.

[0031] In a preferred embodiment, the output shaft 35 and the driven shaft 30 extend into the through hole 202. By placing the output shaft 35 and the driven shaft 30 within the through hole 202, the drive assembly can be concealed, resulting in a simpler and more aesthetically pleasing overall structure. This enhances the product's appearance and improves the user's visual experience. Simultaneously, it provides a relatively enclosed environment for the drive assembly, effectively isolating it from external factors such as dust and moisture. This protective measure extends the service life of the drive components and reduces failures and maintenance costs caused by environmental factors.

[0032] Example 2:

[0033] refer to Figure 5 The first motor 34 is installed inside the through hole 202, and the surface of the sealing disc 33 is provided with a heat dissipation mesh groove 50.

[0034] In the above solution, the first motor 34 is installed in the through hole 202 inside the central column 201 to avoid the first motor 34 being exposed to the outside, thereby further improving the service life of the equipment. At the same time, the first motor 34 inside is cooled by the heat dissipation mesh 50, which does not affect the use of the first motor 34.

[0035] The specific implementation process of this utility model is as follows:

[0036] By controlling the start of the second motor 37, the tilt angle of the central column 201 is adjusted through the meshing of the output tooth 38 and the half-tooth disk 36. By starting the first motor 34, the driven shaft 30 can be automatically driven to rotate through the meshing of the active tooth 351 and the driven tooth 32, thereby changing the shooting direction of the camera 40.

[0037] By simultaneously controlling the use of the second motor 37 and the first motor 34, the tilt angle and direction can be adjusted synchronously according to the needs of use. The adjustment is convenient and quick, and multiple directions can be adjusted synchronously at the same time.

[0038] The above embodiments are merely exemplary models of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
