Description

Technical Field

[0001] The present invention relates to the field of rotating shafts, and particularly to a rotating shaft capable of multi-angle rotation and a screen device. Background Art

[0002] With the continuous evolution of technology, various mechanical and electronic devices are increasingly widely used in people's daily lives and industrial production fields. Among them, as a key mechanical component, rotating shafts are widely present in many devices and are mainly used to achieve physical connections between different components and the function of motion transmission.

[0003] However, in actual application scenarios, when achieving physical connection with the help of a rotating shaft, the problem of electrical connection cannot be ignored. In many devices, electrical connection operations such as power transmission or signal transmission are required between different components, which is crucial for ensuring the normal operation of the device. For example, in some devices where sensors are connected to data processing units, the sensors need to transmit the signals collected by them to the data processing units through electrical connections for analysis and processing; in electric actuators, control signals need to be transmitted to the motor driver through electrical connections to control the operating state of the motor.

[0004] In the design and function realization of traditional rotating shaft structures, the focus is mostly on the construction of mechanical structures and the improvement of physical connection functions, and relatively less consideration is given to the routing channels for electrical connections. In conventional designs, electrical connection routing is often completed by setting routing holes, slots, etc. on the device housing, or by using an external wiring mode to connect wires to the corresponding components. Although these methods can solve the electrical connection problem to a certain extent, there are also many drawbacks.

[0005] On the one hand, operations such as setting routing holes, slots, etc. on the device housing will damage the overall integrity and sealing of the device housing, making it easy for external substances such as dust and moisture to enter the device interior, which will have an adverse impact on the reliability and service life of the device. Especially in application scenarios with high environmental requirements such as outdoor devices and food processing equipment, this damage to the sealing is very likely to cause serious safety hazards and quality problems.

[0006] On the other hand, the use of external wiring not only makes the appearance of the device look messy and affects the overall aesthetics of the product, but also easily causes situations such as wire entanglement and pulling during the wiring process, which brings many inconveniences to the installation, maintenance, and use of the device. In addition, external wiring is exposed to the external environment and is easily affected by electromagnetic interference and mechanical damage, etc., thereby greatly reducing the stability and reliability of the electrical connection. Summary of the Invention

[0052] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention 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 only used to explain the present invention and are not used to limit the present invention.

[0053] See Figures 1-5 , this embodiment provides a rotatable shaft that can rotate at multiple angles, including a mounting base 1, a first rotating shaft group 2 for performing a first-angle rotation on the mounting base 1, and a second rotating shaft group 3 for performing a second-angle rotation on the mounting base 1. Both the first rotating shaft group 2 and the second rotating shaft group 3 include a rotating shaft unit 4;

[0054] The rotating shaft unit 4 includes a rotating shaft 41. One end of the rotating shaft 41 is rotatably connected to the mounting base 1. The other end of the rotating shaft 41 is provided with a connection end 412 for connecting to an external component. A wiring channel 411 penetrating both ends of the rotating shaft 41 is provided inside the rotating shaft 41, and one end of the wiring channel 411 corresponds to the connection end 412; and the other end of the wiring channel 411 of the first rotating shaft group 2 corresponds to the other end of the wiring channel 411 of the second rotating shaft group 3;

[0055] The first rotating shaft group 2 and the second rotating shaft group 3 can be used to connect to two different external components respectively. After the connection, the two different external components can be adjusted for multi-angle rotation; and based on the setting of the wire routing channel 411 in the rotating shaft 41, when the two different external components are electrically connected, the wires can pass through the wire routing channel 411 of the first rotating shaft group 2 and the wire routing channel 411 of the second rotating shaft group 3 in sequence.

[0056] In this embodiment, the rotating shaft further includes a mounting box 5. The mounting seat 1 is fixed in the mounting box 5. One end of the rotating shaft 41 penetrates into the mounting box 5 and is rotatably connected to the mounting seat 1.

[0057] In this embodiment, the number of the second rotating shaft groups 3 is more than two. The other ends of the wire routing channels 411 of the more than two second rotating shaft groups 3 all correspond to the other end of the wire routing channel 411 of the first rotating shaft group 2. The setting that the number of the second rotating shaft groups 3 is more than two can make the connection between the rotating shaft and the external component more stable. Specifically, the rotating shaft can be connected to more than two external components respectively through more than two second rotating shaft groups 3, or can be connected to one external component simultaneously through more than two second rotating shaft groups 3.

[0058] In this embodiment, the mounting seat 1 includes a first mounting member 14. Both ends of the first mounting member 14 are bent at right angles to form second mounting members 15. One end of the rotating shaft 41 of the first rotating shaft group 2 is rotatably connected to the first mounting member 14, and one end of the rotating shafts 41 of the two second rotating shaft groups 3 are respectively rotatably connected to the second mounting members 15 at both ends of the first mounting member 14.

[0059] In this embodiment, a rotating hole 11 is provided on the mounting seat 1. One end of the rotating shaft 41 passes through the rotating hole 11 to be rotatably connected to the mounting seat 1. Specifically, rotating holes 11 are provided on the first mounting member 14 and the second mounting members 15 at both ends thereof.

[0060] In this embodiment, the rotating shaft unit 4 further includes a damping piece 42 for controlling the rotational damping between the mounting seat 1 and the rotating shaft 41. The damping piece 42 is sleeved on the rotating shaft 41, and the damping piece 42 abuts against the mounting seat 1. When the rotating shaft 41 rotates, it will synchronously drive the damping piece 42 to rotate, and the abutment between the damping piece 42 and the mounting seat 1 makes the rotation process have a certain damping.

[0061] In this embodiment, the damping piece 42 is sleeved at one end of the rotating shaft 41, and a first flat position 413 for restricting the rotation of the damping piece 42 is provided at one end of the rotating shaft 41.

[0062] In this embodiment, first flat positions 413 are provided on both sides opposite to one end of the rotating shaft 41.

[0063] In this embodiment, the rotating shaft unit 4 further includes a spring group 43 and a pressing ring 44. The spring group 43 is sleeved on one end of the rotating shaft 41, and one end of the spring group 43 abuts against the damping piece 42. The pressing ring 44 is movably sleeved on one end of the rotating shaft 41 through a thread, and the pressing ring 44 abuts against the other end of the spring group 43. The pressing ring 44 can be rotated to compress the spring group 43, thereby controlling the abutting force of the spring group 43 on the damping piece 42, and finally adjusting the rotational damping when the rotating shaft 41 rotates.

[0064] In this embodiment, the spring group 43 includes a plurality of disc spring pieces 431.

[0065] In this embodiment, a positioning protrusion 421 is provided on one side of the damping piece 42, and a positioning groove 12 corresponding to the positioning protrusion 421 is provided on the mounting base 1. When the damping piece 42 rotates relative to the mounting base 1, a positioning effect is achieved through the cooperation of the positioning protrusion 421 and the positioning groove 12. Specifically, the number of the positioning grooves 12 can also be multiple.

[0066] In this embodiment, first inclined surfaces 4211 are provided on both sides of the positioning protrusion 421, and second inclined surfaces 121 are provided on both sides of the positioning groove 12. The first inclined surfaces 4211 on both sides of the positioning protrusion 421 respectively correspond to the second inclined surfaces 121 on both sides of the positioning groove 12. The cooperation of the first inclined surfaces 4211 and the second inclined surfaces 121 enables the positioning protrusion 421 to be more smoothly disengaged from the positioning groove 12.

[0067] In this embodiment, a limiting portion 451 for limiting the rotation angle of the rotating shaft 41 is provided at the other end of the rotating shaft 41, and a limiting protrusion 13 corresponding to the limiting portion 451 is provided on the mounting base 1.

[0068] In this embodiment, a limiting ring 45 is sleeved on the other end of the rotating shaft 41, and the limiting portion 451 is provided on the limiting ring 45.

[0069] In this embodiment, a second flat portion 414 for limiting the rotation of the limiting ring 45 is provided at the other end of the rotating shaft 41.

[0070] In this embodiment, second flat portions 414 are provided on both sides opposite to the other end of the rotating shaft 41.

[0071] See Figures 1-8, this embodiment also provides a screen device, including a main body 6, a screen 7 and a rotating shaft. The main body 6 is connected to the connection ends 412 of two second rotating shaft groups 3, the screen 7 is connected to the mounting base 1, and the main body 6 is electrically connected to the screen 7 through the wire routing channels 411 of the second rotating shaft group 3 and the wire routing channels 411 of the first rotating shaft group 2 in sequence. Based on the setting of the rotating shaft, not only does the main body 6 and the screen 7 have the function of multi-angle rotation adjustment; at the same time, the wiring method between the main body 6 and the screen 7 is a concealed wiring through the wire routing channels 411 of the second rotating shaft group 3 and the wire routing channels 411 of the first rotating shaft group 2. This wiring method is not only more stable and reliable, but also can effectively avoid potential safety hazards. Specifically, the mounting base 1 of the rotating shaft is fixed to the screen 7 through the mounting box 5 on its outer side.

[0072] In this embodiment, there are two or more screens 7 and rotating shafts. The main body 6 is connected to the connection ends 412 of two or more rotating shafts, two or more screens 7 are respectively connected to the mounting bases of two or more rotating shafts, and the main body 6 is electrically connected to two or more screens 7 through two or more rotating shafts respectively.
