[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described by combining with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Please refer to Figures 1-6The utility model provides a kind of adjustable driving assembly, including main frame 1, the inner wall of main frame 1 is fixedly connected with support shaft 2, the outer wall of support shaft 2 is rotatably connected with rotating frame 3, so that rotating frame 3 can be flexibly rotated around support shaft 2, adjusting assembly 4 is provided on main frame 1, adjusting assembly 4 is specifically composed of hinged rod one 41, hinged base 42, electric cylinder seat 43, hinged block 44 and hinged rod two 45, driving assembly 5 is provided on rotating frame 3, adjusting assembly 4 includes hinged rod one 41, the inner wall of main frame 1 is fixedly connected with hinged rod one 41, the outer wall of hinged rod one 41 is hinged with hinged base 42, the outer wall of hinged base 42 is fixedly connected with electric cylinder seat 43, the output end of electric cylinder seat 43 is fixedly connected with hinged block 44, the inner wall of rotating frame 3 is fixedly connected with hinged rod two 45, the end of hinged block 44 away from electric cylinder seat 43 is hinged on the outer wall of hinged rod two 45, when the position of driving assembly needs to be adjusted, start electric cylinder seat 43.The output end of electric cylinder seat 43 pushes hinged block 44 to move linearly, since hinged block 44 is hinged with hinged rod two 45, the movement of hinged block 44 will drive the position of hinged rod two 45 to change.And hinged rod two 45 is fixed on rotating frame 3, so rotating frame 3 will rotate around support shaft 2 on main frame 1.The rotation of rotating frame 3 will further drive the position of driving wheel 54 in driving assembly 5 to change.By this way, driving wheel 54 can conveniently adapt to different thicknesses of slide rail, so as to improve the applicability and flexibility of the adjustable driving assembly.

[0029] In the utility model, the driving assembly 5 includes driving motor 51, the inner wall of rotating frame 3 is rotatably connected with rotating shaft 52 by bearing, and the power transmission between driving motor 51 and rotating shaft 52 is realized by synchronous toothed belt transmission assembly 53, and synchronous toothed belt transmission assembly 53 is composed of driving wheel, synchronous toothed belt and transmission wheel.

[0030] Furthermore, a sheet metal part 6 is fixedly connected to the outer wall of the rotating frame 3, and a protective cover 7 is connected to the sheet metal part 6. The sheet metal part 6 is fixed to the protective cover 7 by screws and nuts. The sheet metal part 6 has a curved design. When the rotating frame 3 rotates, it can drive the sheet metal part 6 and the protective cover to rotate synchronously, ensuring that the protective cover 7 protects the synchronous toothed belt drive assembly 53.

[0031] Furthermore, a counterweight rod 8 is fixedly connected to the outer wall of the main frame 1, and a counterweight block 9 is fixedly connected to the counterweight rod 8. The counterweight block 9 is installed on the side of the main frame 1 away from the drive motor 51. By adjusting the number and weight of the counterweight blocks 9, the center of gravity distribution of the main frame 1 can be accurately balanced, effectively avoiding the problem of unilateral imbalance caused by the concentrated arrangement of the drive motor 51, preventing tilting, increased vibration or abnormal wear of transmission components during equipment operation, and significantly improving the stability and reliability of the drive components.

[0032] Furthermore, the main frame 1 is provided with a weight reduction slot 10, and the rotating frame 3 is provided with a weight reduction slot 11. The weight of the main frame 1 can be reduced by the weight reduction slot 10, thereby reducing the overall load of the equipment. The weight of the rotating frame 3 can be reduced by the weight reduction slot 11, thereby reducing the load of the electric cylinder base 43.

[0033] Furthermore, auxiliary conical wheels 12 are rotatably connected to the main frame 1. Four sets of auxiliary conical wheels 12 are symmetrically distributed on both sides of the main frame 1 in a 2:2 configuration. Each auxiliary conical wheel 12 has a frustum-shaped design, with the side closer to the main frame 1 being larger and the other smaller. The larger side also has an anti-slip protrusion. Through the cooperation of the four sets of auxiliary conical wheels 12, when the equipment tilts, the contact state between the two auxiliary conical wheels and the contact surface differs due to the frustum-shaped design and the larger side closer to the main frame 1. Specifically, the contact area between the larger end of the auxiliary conical wheel 12 on the tilted side and the contact surface increases, resulting in increased friction; while the contact area and friction of the auxiliary conical wheel 12 on the other side are relatively smaller. This difference in friction between the two sides creates a reverse torque, which acts on the main frame 1, causing the equipment to rotate back, thereby gradually correcting the tilt and achieving self-correction. Meanwhile, the anti-slip protrusion on the larger side further increases the contact friction, making the self-correction effect more obvious. This effectively avoids problems such as instability and derailment caused by continuous equipment tilt, thus significantly improving the equipment's operational stability. It can generate a self-correction effect when tilted, thereby improving the equipment's operational stability.

[0034] In use, when it is necessary to adapt the drive wheel 54 to slide rails of different thicknesses, the electric cylinder base 43 in the adjustment assembly 4 is activated. The electric cylinder base 43 starts working, and its output end performs a linear extension and retraction motion, pushing the hinge block 44 fixedly connected to it to move linearly.

[0035] Since the hinge block 44 is hinged on the hinge rod two 45 on the inner wall of the rotating frame 3 away from the end of the electric cylinder base 43, and the hinge rod one 41 is fixed on the inner wall of the main frame 1 and connected with the electric cylinder base 43 through the hinge base 42, such a connection structure makes the linear movement of the hinge block 44 drive the position of the hinge rod two 45 to change.

[0036] In addition, since the hinge rod two 45 is fixed on the rotating frame 3, and the rotating frame 3 is rotationally connected with the support shaft 2 on the inner wall of the main frame 1, the rotating frame 3 will rotate on the main frame 1 around the support shaft 2. With the rotation of the rotating frame 3, the driving assembly 5 installed on the rotating frame 3 will also move, thereby driving the position of the driving wheel 54 in the driving assembly 5 to change until the driving wheel 54 is adjusted to the appropriate position to adapt to the slide rails of different thicknesses.

[0037] During the operation of the device, if the device is inclined, the four groups of auxiliary bevel gears 12 will play a self-correcting role. The contact area between the large end of the auxiliary bevel gear 12 on the inclined side and the contact surface increases, and the friction force increases. The contact area and friction force of the auxiliary bevel gear 12 on the other side are relatively small, and the difference between the friction forces on both sides forms a reverse torque acting on the main frame 1, so that the device rotates back to correct the inclination. At the same time, the driving motor 51 is started, and the output end drives the driving wheel to rotate, and the power is transmitted to the transmission wheel on the rotating shaft 52 through the synchronous toothed belt, so that the rotating shaft 52 rotates, thereby driving the driving wheel 54 to rotate, and providing driving power for the entire device. In this process, the metal part 6 on the outer wall of the rotating frame 3 and the protective cover 7 will rotate synchronously with the rotating frame 3, continuously protecting the synchronous toothed belt transmission assembly 53. In addition, the counterweight 9 and the lightening slot one 10 on the main frame 1 and the lightening slot two 11 on the rotating frame 3 ensure the balance of the center of gravity of the device and reduce the weight of the device, respectively, to ensure the stable operation of the device.

[0038] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation made according to the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
