[0033] The embodiment of the present application discloses a driving device, which can be applied to a lighting console to improve the transmission smoothness and structural stability of the screen flipping of the lighting console. The lighting console includes a fixed frame, a screen and a driving device.

[0034] For the convenience of understanding the structures of the driving device and the lighting console, the driving device and the lighting console will be further described below in conjunction with the embodiments and the drawings.

[0035] Please refer to Figure 1 and Figure 2, an embodiment of the present application provides a lighting console 200, which includes a driving device 100, a fixing bracket 201, and a screen 202. Specifically, please refer to Figures 3 to 6 , the driving device 100 includes a driving member 10, a driving gear 20, a driven gear 30, and a backlash elimination assembly 40. The driving gear 20 is connected to the output end of the driving member 10, the driven gear 30 is meshed and connected to the driving gear 20, the driven gear 30 is used to connect the screen 202, the backlash elimination assembly 40 includes a backlash elimination gear 41, a connecting shaft 42, and a locking member 43. The connecting shaft 42 passes through the fixing bracket 201 and is rotatable relative to the fixing bracket 201. The backlash elimination gear 41 and the locking member 43 are respectively connected to both ends of the connecting shaft 42 and are respectively located on both sides of the fixing bracket 201, and the locking member 43 directly or indirectly abuts against the fixing bracket 201. The backlash elimination gear 41 is spaced from the driving gear 20 and is meshed and connected to the driven gear 30.

[0036] In this way, by setting the driving gear 20 and the backlash elimination gear 41 to be respectively meshed and connected to the driven gear 30, and enabling the connecting shaft 42 to pass through the fixing bracket 201, the damping assembly and the locking member 43 are respectively connected to both ends of the connecting shaft 42 and are respectively located on both sides of the fixing bracket 201, and the locking member 43 directly or indirectly abuts against the fixing bracket 201. When the driving member 10 drives the driving gear 20 to rotate, the driven gear 30 drives the backlash elimination gear 41 to rotate. When the backlash elimination gear 41 rotates, it drives the locking member 43 to rotate through the connecting shaft 42. At this time, a relative frictional force is generated between the locking member 43 and the fixing bracket 201 and is transmitted to the backlash elimination gear 41. The backlash elimination gear 41 generates a damping force that prevents the driven gear 30 from rotating under the action of the frictional force. As a result, the driven gear 30 rotates driven by the driving gear 20 on the one hand, and on the other hand, has a tendency to stop rotating under the limitation of the backlash elimination gear 41. By the cooperation of the driving gear 20 and the backlash elimination gear 41, it is beneficial to eliminate the transmission backlash between the driven gear 30 and the driving gear 20, thereby improving the structural reliability of the driving device 100, improving the transmission smoothness and structural stability of the screen 202 flipping of the lighting console 200, and further improving the touch experience and operation accuracy of the screen 202.

[0037] Optionally, considering that the lighting console 200 is mostly driven by a single-sided motor when flipping the screen 202, due to the single-sided force, the side connected to the driving motor will move first, and there will be a certain lag on the driven side, resulting in the two sides of the screen 202 being unable to flip or position simultaneously, and it is easy to cause the phenomenon of the screen 202 being skewed, thus affecting the user experience. In the long term, mechanical failures may also occur. Based on this, the number of driving devices 100 can be two, and the two driving devices 100 are respectively connected to both sides of the screen 202, which can help maintain the force balance on both sides of the screen 202, facilitate the simultaneous flipping or positioning of both sides of the screen 202, maintain the stability of the screen 202 after flipping, and improve the user experience and the overall structural reliability.

[0038] Optionally, the driving member 10 can be a motor. The motor is installed on the fixing frame 201, and the driving motor drives the driving gear 20 to rotate, so as to drive the screen 202 to flip through the driven gear 30, thereby realizing the electric control of the screen flipping, which is beneficial to improving the transmission stability and structural stability of the screen 202 flipping.

[0039] It should be noted that when the driving member 10 is powered off, the operator can also manually rotate the screen 202. At this time, the driven gear 30 drives the driving gear 20 and the backlash elimination gear 41 to rotate, so as to realize the power-off screen flipping.

[0040] It can be understood that in some other embodiments, the driving member 10 can also be a handle. By manually driving the handle by the operator, the driving gear 20 is driven to rotate, so that the screen 202 can be flipped without power.

[0041] Please combine Figure 2 and Figure 3 In some embodiments, a first installation groove 2011 and a second installation groove 2012 are provided on one side of the fixing frame 201 close to the driving gear 20. The first installation groove 2011 communicates with the second installation groove 2012, and the driving gear 20 is installed in the first installation groove 2011, and the driven gear 30 and the backlash elimination gear 41 are installed in the second installation groove 2012.

[0042] In this way, by setting the first installation groove 2011 and the second installation groove 2012, it is not only beneficial to positioning and assembly, improving the convenience of installation, but also can reasonably utilize space, which is beneficial to the miniaturized design of the driving device 100.

[0043] It can be understood that in some other embodiments, the driving gear 20 and the driven gear 30 can also be installed in the first installation groove 2011, and the backlash elimination gear 41 is installed in the second installation groove 2012.

[0044] Optionally, the depth of the first mounting groove 2011 is greater than that of the second mounting groove 2012, so as to be able to adapt to the driving gear 20 with a greater thickness, thereby improving the strength and load-bearing capacity of the driving gear 20, which is beneficial to improving the reliability of the driving device 100 and facilitating the driving device 100 to adapt to a screen 202 with a greater weight.

[0045] Please refer to Figure 4 and Figure 5 In some embodiments, the driving member 10 and the locking member 43 are located on the same side of the fixing frame 201. This can help reduce the axial dimension of the connecting shaft 42, thereby reducing the volume of the driving device 100, and further reducing the occupied space of the driving device 100 in the lighting console 200, which is beneficial to the miniaturization design of the lighting console 200.

[0046] Optionally, the backlash elimination gear 41 is arranged on the side of the driven gear 30 close to the driving gear 20. This can improve the structural compactness on the premise of ensuring that the backlash elimination gear 41 does not contact and interfere with the driving gear 20, thereby helping to reduce the volume of the driving device 100, which is beneficial to the miniaturization design of the lighting console 200.

[0047] Optionally, the diameter of the driving gear 20 is greater than that of the driven gear 30, and the diameter of the driven gear 30 is greater than that of the backlash elimination gear 41. That is, the diameter of the gears gradually decreases in the driving force transmission direction of the driving member 10, so as to ensure the load-bearing capacity of the driving gear and improve the transmission efficiency and performance of the driving device 100. In addition, the smaller diameter of the backlash elimination gear 41 can help reduce the size of the backlash elimination gear 41, which is beneficial to installing the backlash elimination gear 41 on the side of the driven gear 30 close to the driving gear 20 and reducing the volume of the driving device 100.

[0048] Please refer to Figure 6 In some embodiments, the backlash elimination assembly 40 further includes a first intermediate member 44. The first intermediate member 44 is sleeved on the outer periphery of the connecting shaft 42 and is located between the fixing frame 201 and the locking member 43. One side of the first intermediate member 44 abuts against the locking member 43 indirectly or directly, and the other side of the first intermediate member 44 abuts against the fixing frame 201 directly or indirectly.

[0049] In this way, by providing a first intermediate member 44 between the fixing bracket 201 and the locking member 43, wear between the fixing bracket 201 and the locking member 43 can be reduced, which is conducive to reducing the maintenance cost of components. When the backlash elimination gear 41 rotates, the connecting shaft 42 drives the locking member 43 to rotate relative to the first intermediate member 44, so that the locking member 43 and the first intermediate member 44 rotate and rub against each other to generate frictional force. Alternatively, the connecting shaft 42 drives the locking member 43 and the first intermediate member 44 to rotate relative to the fixing bracket 201, so that the first intermediate member 44 and the locking member 43 rotate and rub against each other to generate frictional force. The frictional force is transmitted to the backlash elimination gear 41 through the connecting shaft 42 to prevent the driven gear 30 from rotating and eliminate the backlash between the driven gear 30 and the driving gear 20.

[0050] Optionally, the first intermediate member 44 is elastic along the axial direction of the connecting shaft 42.

[0051] In this way, when any one of the first intermediate member 44, the locking member 43, and the fixing bracket 201 is worn, the first intermediate member 44 can deform under the action of the elastic force to offset the size of the worn part, so that the first intermediate member 44 always maintains a fitting connection with the fixing bracket 201 and the locking member 43, thereby ensuring the frictional force between the first intermediate member 44 and the fixing bracket 201 and the locking member 43, ensuring the damping force of the backlash elimination assembly 40 on the driven gear 30, and ensuring the backlash elimination effect.

[0052] Optionally, the first intermediate member 44 can be any one of a spring washer, a spring, an elastic flat washer, etc., which can be specifically set according to actual needs and are not limited here.

[0053] It can be understood that in some other embodiments, the first intermediate member 44 can also be a gasket or other non-elastic materials.

[0054] Optionally, the number of the first intermediate members 44 can be multiple, and the multiple first intermediate members 44 are arranged at intervals, so that the movement stroke of the locking member 43 can be reduced, facilitating the assembly of the backlash elimination assembly 40, and at the same time ensuring the frictional force between the first intermediate member 44 and the fixing bracket 201 and the locking member 43, so as to ensure the damping force of the backlash elimination assembly 40 on the driven gear 30.

[0055] It can be understood that in some other embodiments, the number of the first intermediate members 44 can also be one.

[0056] In some embodiments, the locking member 43 is movably connected to the connecting shaft 42 along the axial direction of the connecting shaft 42. Thus, the degree of elastic deformation of the locking member 43 can be adjusted to obtain different magnitudes of frictional force when the backlash elimination gear 41 rotates, so as to adjust the damping force of the backlash elimination gear 41 on the driven gear 30. Furthermore, the damping force of the backlash elimination assembly 40 can be adaptively adjusted according to the weight of the actual screen 202, etc., which is beneficial to ensuring the transmission smoothness and structural stability of the screen 202 flipping and improving the usage experience of the lighting console 200.

[0057] Optionally, the connection manner between the locking member 43 and the connecting shaft 42 can be any one of threaded connection, sliding connection, or connection through an elastic member, etc., which can be specifically set according to actual requirements and is not limited here.

[0058] In one example, the connection manner between the locking member 43 and the connecting shaft 42 is threaded connection. Optionally, an external thread is provided at one end of the connecting shaft 42 away from the backlash elimination gear 41, and a threaded hole is provided in the locking member 43, and the locking member 43 is threadedly connected to the connecting shaft 42.

[0059] In this way, by helically adjusting the connection position between the locking member 43 and the connecting shaft 42, the pressing force of the locking member 43 on the first intermediate member 44 is adjusted, so as to adjust the relative rotational frictional force between the first intermediate member 44, the fixing bracket 201, and the locking member 43. Adopting the threaded connection manner between the locking member 43 and the connecting shaft 42 can make the adjustment of the elastic deformation of the first intermediate member 44 simpler and more convenient. At the same time, it is also convenient for the disassembly, installation, and replacement of the locking member 43 and the first intermediate member 44, so as to facilitate the update and maintenance of the backlash elimination assembly 40.

[0060] It can be understood that in some other embodiments, the locking member 43 and the connecting shaft 42 can also be threadedly connected by providing a threaded hole in the connecting shaft 42 and using a bolt, screw, or screw rod for the locking member 43.

[0061] In another example, the connection manner between the locking member 43 and the connecting shaft 42 is connection through an elastic member. Optionally, one end of the elastic member is connected to the connecting shaft 42 or the fixing bracket 201, and the other end of the connecting shaft 42 is connected to the locking member 43, and the locking member 43 abuts against the first intermediate member 44 under the limitation of the elastic force.

[0062] In some embodiments, the backlash elimination assembly 40 further includes a second intermediate member 45, and the second intermediate member 45 is sleeved on the outer periphery of the connecting shaft 42 and is located between the fixing bracket 201 and the backlash elimination gear 41. Thus, the wear between the fixing bracket 201 and the backlash elimination gear 41 can be reduced to protect the backlash elimination gear 41, which is beneficial to extending the service life of the backlash elimination gear 41 and reducing the maintenance cost of the components.

[0063] Optionally, the backlash elimination assembly 40 may further include a third intermediate member 46. The third intermediate member 46 is sleeved on the outer periphery of the connecting shaft 42 and is located between the fixing bracket 201 and the first intermediate member 44, so that one side of the first intermediate member 44 abuts against the locking member 43, and the other side of the first intermediate member 44 is connected to the fixing bracket 201 through the third intermediate member 46. Thereby, the wear between the fixing bracket 201 and the first intermediate member 44 can be reduced to protect the first intermediate member 44, and further extend the service life of the first intermediate member 44, ensuring the backlash elimination effect of the backlash elimination assembly 40.

[0064] Optionally, the second intermediate member 45 and the third intermediate member 46 may be any one of a gasket, a spacer block or a backing plate, etc., and may be specifically set according to actual needs, and are not limited herein.

[0065] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present application within the scope of knowledge possessed by those of ordinary skill in the art.
