Description

Technical Field

[0001] The utility model relates to the technical field of rotating shafts, and more specifically, to a rotating shaft structure for electric opening and closing. Background Art

[0002] A rotating shaft is an essential component for connecting the main parts of a product. A shaft that bears both bending moment and torque during rotational work is called a rotating shaft. Common rotating shafts include: mobile phone rotating shafts (flip or rotating screen mobile phones), laptop computer rotating shafts, portable DVD rotating shafts, LED table lamp rotating shafts, LCD display rotating shafts, in-vehicle bracket rotating shafts such as GPS, etc. However, when the current rotating shaft structure is in use, manual control is required for its opening and closing. The operator uses both hands to assist the two connection points of the rotating shaft to rotate, achieving its opening and closing. This is time-consuming and laborious, and the degree of automation is limited. Especially when the operator's other hand is occupied and only one hand can be used for operation, it is inconvenient to control the opening and closing of the rotating shaft, and the scope of application is limited. In view of this, we propose a rotating shaft structure for electric opening and closing. Summary of the Utility Model

[0004] To achieve the above purpose, the present utility model provides a rotating shaft structure for electric opening and closing, including an outer housing and an inner housing adaptively installed inside the outer housing. On both sides near the two ends of the inner housing, mechanical connection components are provided. The two mechanical connection components on the same side both extend out of the inner housing cavity movably for connecting the main parts of the product to rotate.

[0005] Between the two mechanical connection components at the same end, a gear linkage component is provided. A driving motor is also provided inside the inner housing. The output end of the driving motor drives the gear linkage component to rotate, driving the mechanical connection components on both sides to rotate and close in opposite directions, and increasing the distance between the front end of the mechanical connection component and the inner housing.

[0006] As a further improvement of this technical solution, the mechanical connection component at least includes a driving link movably connected to the end of the inner housing cavity.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] A rotating shaft is an essential part for connecting the main components of a product. A shaft that bears both bending moment and torque during rotational work is called a rotating shaft. Common rotating shafts include: mobile phone rotating shafts (flip or rotating screen mobile phones), notebook computer rotating shafts, portable DVD rotating shafts, LED table lamp rotating shafts, LCD display rotating shafts, in-vehicle bracket rotating shafts such as GPS, etc. Please refer to Figures 1 - 4 As shown, this embodiment provides a rotating shaft structure with electric opening and closing, including an outer casing 100 and an inner casing 110 adaptively installed inside the outer casing 100. Mechanical connection assemblies 220 are provided on both sides of the inner casing 110 near both ends. The two mechanical connection assemblies 220 on the same side both extend out of the inner cavity of the inner casing 110 movably for connecting the main components of the product to rotate;

[0025] A gear linkage assembly 210 is provided between the two mechanical connection assemblies 220 at the same end. A driving motor 200 is also provided inside the inner casing 110. The output end of the driving motor 200 drives the gear linkage assembly 210 to rotate, driving the mechanical connection assemblies 220 on both sides to rotate in opposite directions and close, and increasing the distance between the front end of the mechanical connection assembly 220 and the inner casing 110;

[0026] As Figures 1 - 3 shown, the present invention considers that when the current rotating shaft structure is in use, it needs to be manually controlled for opening and closing. The operator rotates the two connection points of the rotating shaft with both hands to achieve its opening and closing, which is time-consuming and laborious, and the degree of automation is limited. Especially when the operator's other hand is occupied and can only be operated with one hand, it is inconvenient to control the opening and closing of the rotating shaft, and the scope of application is limited. Therefore, when two main components of the product are installed on the two mechanical connection assemblies 220 on the same side and the two main components of the product are connected, the output end of the driving motor 200 drives the gear linkage assembly 210 to rotate, realizing the relative rotation of the mechanical connection assemblies 220 on both sides, and driving the opening and closing of the two main components of the product more conveniently. Only one hand needs to control the rotation of the driving motor 200 to close, and controlling the driving motor 200 to reverse can open, improving the scope of use;

[0027] Regarding the single - hand control of the drive motor 200, a suitable motor driver can be selected, such as L298N, TB6612FNG, etc. These drivers can control the forward and reverse rotation of a DC motor. Connect the motor driver to the motor and the control board (such as Arduino, Raspberry Pi, etc.). Generally, the input end of the motor driver is connected to the GPIO (General - Purpose Input / Output) pin of the control board, and the output end of the motor driver is connected to the motor. Write a program using a programming language (such as Python, C++) to control the motor driver by controlling the high and low levels of the GPIO pin, thereby controlling the rotation direction of the motor. Then, use a graphical interface library (such as Tkinter, PyQt, etc.) in the product to create a simple control interface that includes two buttons, respectively used to control the forward and reverse rotation of the motor;

[0028] Moreover, when the two main components of the product are linked and closed, in order to ensure the adaptation of the product size and provide sufficient folding space for the product, when the front end of the mechanical connection component 220 is in the closed state, it extends towards the outside of the inner shell 110, providing enough space for the product to fold and improving the safety performance.

[0029] Based on the above, the specific structure needs to be disclosed in detail:

[0030] First of all, to enable the mechanical connection component 220 to link the main mechanical components of the product and meet the basic function of the rotating shaft structure that bears both bending moment and torque during rotation, the specific structure of the mechanical connection component 220 needs to be disclosed in detail. Please refer to Figure 4 , so that the mechanical connection component 220 at least includes a driving link 221 movably connected to the end of the inner cavity of the inner shell 110. The end of the driving link 221 rotates out from the notch opened on the outer wall of the inner shell 110, and an installation frame 223 is provided at the end of the driving link 221 away from the inner shell 110. Threaded holes 2230 for installing the main components of the product are provided on the surface of the installation frame 223. Align the bolts with the threaded holes 2230 to install and fix the main components of the product. When the end of the driving link 221 rotates inside the inner shell 110, it drives the main components of the product to rotate, realizing the rotational cooperation of the two main components of the product on the same side for opening and closing. Among them:

[0031] A connecting rod 222 is fixedly connected between the two driving links 221 on the same side. The two driving links 221 on the same side are connected in series through the connecting rod 222, increasing the pulling force between the two driving links 221 and making the overall rotation more stable.

[0032] Then, the gear linkage component 210 drives the two driving links 221 on the same side to rotate in opposite directions, realizing that the driving motor 200 drives one of the driving links 221 to rotate, and the other driving link 221 will automatically rotate in the opposite direction. Please refer toFigure 4 Furthermore, the structure of the gear linkage assembly 210 is further disclosed. The gear linkage assembly 210 at least includes two symmetric driving gears 211 rotating at the end of the inner cavity of the housing 110. An even number of driven gears 212 are arranged between the driving gears 211. The two driving gears 211 and the even number of driven gears 212 are meshed and matched with each other adjacent. According to the prior art, those skilled in the art of this technology can easily understand that when an even number of gear sets are meshed, the two gear sets at the outermost edges rotate relatively. To enable the opening and closing of the two main components of the product, it is necessary to make the driving link rods 221 on both sides rotate in opposite directions. Therefore, when one of the driving gears 211 rotates, the two driving gears 211 and the even number of driven gears 212 are simultaneously meshed and rotated, driving the two driving link rods 221 on the same side to rotate in opposite directions. The even number of driven gears 212 can be 2, 4, etc. The more the number of driven gears 212, the more stable the rotation.

[0033] Specifically, the end parts of the two driving link rods 221 at the same end are respectively fixedly connected to the end parts of the two driving gears 211. The output end of the driving motor 200 is fixedly connected to the end part of one of the driving gears 211, so as to realize that the output end of the driving motor 200 drives the driving gear 211 to rotate. Through the meshing rotation of the even number of driven gears 212, the other driving gear 211 is driven to rotate in the opposite direction.

[0034] Moreover, in order to enable one gear linkage assembly 210 to drive the two gear linkage assemblies 210 at both ends of the inner housing 110 to rotate when rotating, a linkage rod 213 is fixedly connected between the two driving gears 211 respectively close to the ends of the two inner housings 110. The linkage rod 213 is located in the inner cavity of the inner housing 110 and rotates simultaneously with the driving gear 211. This is beneficial to driving the other driving gear 211 to rotate through the linkage rod 213 when the driving motor 200 drives the gear linkage assembly 210 close to one end of the inner housing 110 to rotate, so that the two gear linkage assemblies 210 rotate simultaneously, making the structure more compact and complete.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
