Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a rotating shaft component and a robot. Background Art

[0002] The development of companion robots is bringing robotics technology from industry to the home, addressing both physical and emotional needs. Human-robot interaction occurs in three forms: screen interaction, voice interaction, and visual interaction. Screen interaction is the most common method of human-robot interaction. Generally speaking, the screen is fixedly embedded in the robot body, and the viewing angle cannot be adjusted, making it difficult to meet the operating posture requirements of everyone. Therefore, a screen rotation axis embedding method is constructed to enable the screen posture to meet the needs of various groups.

[0003] The screen mounting structure used in related art is a straight-line round bar or a Z-shaped damping hinge. However, this structure creates a certain amount of deformation pressure on the bottom surface of the structure connected to the screen when the screen rotates (opens and closes). Furthermore, when adjusting the screen angle, the hinge is subjected to high stress, making it prone to damage and resulting in a short service life. Utility Model Content

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] See also Figure 4 and Figure 5 The present invention provides a rotating shaft 110 assembly 100 suitable for mounting a display screen 200 or other structure requiring rotation. It should be noted that the display screen 200 can be a laptop computer display screen 200 or a display screen 200 mounted on a robot 10. The rotating shaft 110 assembly 100 comprises a rotating shaft 110, a connecting member 120, an elastic member 130, and a stopper 140. One end of the rotating shaft 110 is connected to the display screen 200, and the other end is connected to the stopper 140. The connecting member 120 is connected to the rotating shaft 110 and configured to rotate relative to the rotating shaft 110 to facilitate adjustment of the angle of the display screen 200. The elastic member 130 is mounted on the rotating shaft 110 and is located on the side of the connecting member 120 away from the display screen 200. The elastic member 130 provides a damping force for the rotation of the display screen 200, ensuring the stability of the display screen 200 at different angles, thereby ensuring the stability of the rotation angle of the display screen 200 and improving the user experience. It should be noted that the elastic member 130 includes, but is not limited to, an elastic washer, a spring, or other structures capable of providing a damping force. The stopper 140 is located on the side of the elastic member 130 away from the connector 120 and is configured to limit the elastic member 130 to prevent it from falling off the shaft 110. This not only secures the stopper 140 but also ensures the safety and reliability of the entire shaft 110 assembly 100.

[0046] Among them, the connecting member 120 includes a first connecting portion 121 and a second connecting portion 122. The first connecting portion 121 is provided with a through hole 1211. The end of the rotating shaft 110 away from the display screen 200 is passed through the through hole 1211. Specifically, one end of the rotating shaft 110 is connected to the display screen 200, and the other end passes through the through hole 1211 of the first connecting portion 121, and the first connecting portion 121 extends perpendicularly to the direction of the rotating shaft 110, ensuring the stability of the structure. The second connecting portion 122 is configured to be able to connect to an external device. The extension direction of the first connecting portion 121 is perpendicular to the extension direction of the rotating shaft 110, so that the first connecting portion 121 can provide good support for the rotating shaft 110, while effectively obtaining the force transmitted by the rotating shaft 110, reducing the stress on the rotating shaft 110 during the angle adjustment of the display screen 200. The extension direction of the second connection part 122 is perpendicular to the extension direction of the first connection part 121, so that the second connection part 122 can provide effective support for the first connection part 121 while effectively transmitting the force exerted on the first connection part 121 to the external device, so as to reduce the stress at the shaft 110 assembly 100 and reduce the risk of damage to the shaft 110 assembly 100, thereby increasing the service life.

[0047] Specifically, the hinge 110 assembly 100 provided by the present invention allows the user to conveniently adjust the angle of the display screen 200 while maintaining stability at the selected angle, thereby improving the user experience. In addition, since a simple mechanical structure is used to achieve these functions, the cost is low and it is easy to manufacture and maintain.

[0048] See also Figure 4 In some embodiments, the second connection portion 122 includes a first connection tab 1221 and a second connection tab 1222 spaced apart from each other, with the first connection tab 1221 and the second connection tab 1222 located on either side of the axis of the hinge 110. Consequently, the force applied to the hinge 110 is transmitted to the first connection tab 1221 and the second connection tab 1222 via the first connection portion 121, effectively dispersing the force while ensuring uniformity across the hinge 110 assembly 100. Furthermore, this configuration allows the second connection portion 122 to better adapt to external device connection requirements, increasing connection flexibility and versatility.

[0049] Specifically, by designing the second connection portion 122 to include two first connection tabs 1221 and a second connection tab 1222 located on either side of the axis of the hinge 110, torque distribution is more even when connecting to an external device, reducing stress on a single connection point and thereby extending the service life of the hinge 110 assembly 100. This design also facilitates connection operations in confined spaces, as the two tabs can provide connection possibilities in different directions. It should be noted that the extension direction of the first connection tab 1221 can be the same as or different from the extension direction of the second connection tab 1222.

[0050] The provision of the first and second connection tabs 1221, 1222 further enhances the applicability of the hinge 110 assembly 100, enabling it to be used not only for general display 200 installation but also for specialized installations, such as those requiring a compact layout or connection in a specific orientation. Furthermore, a secure and reliable connection can be achieved even in limited spaces, enhancing the overall performance of the product.

[0051] In some embodiments, the distance from the axis of the hinge 110 to the side of the second connection portion 122 facing away from the hinge 110 along a first direction X is greater than the thickness of the display 200. The first direction X is perpendicular to the axis of the hinge 110 and the extension direction of the first connection portion 121. This ensures that during adjustment of the display 200, even when the display 200 reaches its maximum adjustment angle, the end of the display 200 proximal to the hinge 110 assembly 100 will not come into contact with any potential obstacles, thereby ensuring sufficient operating space between the display 200 and the hinge 110 assembly 100. Furthermore, after the display 200 is adjusted, it can be stored in the space provided by the hinge 110 and the second connection portion 122, preventing excessive protrusion and possible scratches, improving the aesthetics while ensuring the safety of the display 200.

[0052] Specifically, by ensuring that the distance from the axis of the rotating shaft 110 to the side of the second connecting portion 122 facing away from the rotating shaft 110 is greater than the thickness of the display screen 200, unnecessary interference between the display screen 200 and the surrounding environment during rotation can be avoided. This design, particularly when used in a robot 10 or other device, provides more flexible installation options and reduces potential physical collision risks. For example, when the display screen 200 needs to be installed close to a wall or other surface, this design prevents the display screen 200 from contacting such objects and affecting its rotation range.

[0053] See also Figure 4 In some embodiments, the second connection portion 122 extends parallel to the direction of the rotation shaft 110. The design of the second connection portion 122 being parallel to the rotation shaft 110 means that it can be connected to the external device directly along the axis of the rotation shaft 110, which not only simplifies the installation process but also reduces problems caused by angular deviation. This feature is particularly important for mobile platforms such as the robot 10, as it ensures that the display screen 200 always maintains the correct posture and position in dynamic environments, without affecting the visual effect or causing mechanical failure due to changes in the angle of the connection.

[0054] Specifically, when the extension direction of the second connection portion 122 is parallel to the extension direction of the rotating shaft 110, during the installation process, the relative positioning between the two is only adjusted along the straight line direction, which reduces the difficulty of repeated positioning and adjustment during the installation process, thereby improving the installation efficiency. In addition, the extension direction of the second connection portion 122 is parallel to the extension direction of the rotating shaft 110, which can also make the stress evenly distributed in the entire connection area, thereby enhancing the overall strength and durability of the rotating shaft 110 assembly 100. This not only provides a more stable and smooth operating experience, but also enables the rotating shaft 110 assembly 100 to be suitable for application scenarios that require frequent adjustment of the angle of the display screen 200. In addition, the parallel arrangement also helps to achieve a more compact product design, save space resources, and facilitate maintenance and repair, because all related components are arranged on the same axis, which is easy to access and handle.

[0055] See also Figure 5 In some embodiments, the elastic member 130 includes multiple spring clips 131 (which may be elastic washers). It should be noted that the number of spring clips 131 can be four, five, or six, etc. Each spring clip 131 has a warped portion (each spring clip 131 achieves its elastic function through deformation of the warped portion), and the warped portions of adjacent spring clips 131 are positioned differently. This ensures that the elastic member 130 can provide stable support. During rotation, the interaction between the spring clips 131 effectively disperses stress, thereby extending the service life and improving system reliability. Furthermore, when the display screen 200 is rotated to the desired angle, the spring clips 131 provide resistance, preventing the display screen 200 from resetting and improving the stability of the display screen 200's angle adjustment.

[0056] Specifically, the warped portions of adjacent spring pieces 131 are located at different positions. When these spring pieces 131 are combined, they form a complex three-dimensional structure. This allows each spring piece 131 to deform in a unique manner when subjected to force, thereby complementing the other spring pieces 131 and avoiding excessive stress concentration in a single direction. Specifically, when the rotating shaft 110 rotates relative to the connecting member 120, the elastic member 130 will deform accordingly. Because the warped portions of adjacent spring pieces 131 are located at different positions, the amount and direction of deformation produced by each spring piece 131 under the same conditions are different. This characteristic not only helps absorb energy fluctuations during rotation, but also balances the stress distribution within the entire elastic member 130 through the interaction between the spring pieces 131, reducing the risk of fatigue damage. In addition, the spring pieces 131 provide more uniform and lasting resistance, ensuring the stability of the display screen 200 at any angle.

[0057] See also Figure 5In some embodiments, the rotating shaft 110 assembly 100 further includes a first gasket 150 and a second gasket 160. The first gasket 150 is sleeved on the rotating shaft 110 and located between the connecting member 120 and the elastic member 130, while the second gasket 160 is also sleeved on the rotating shaft 110 but located between the elastic member 130 and the retaining member 140. The presence of these two gaskets adds an additional layer of protection to the entire rotating shaft 110 assembly 100, preventing wear caused by direct contact between the elastic member 130, the connecting member 120, and the retaining member 140. This improves the internal friction performance of the rotating shaft 110 assembly 100, reduces the possibility of noise generated during relative motion, and also protects the elastic member 130 from external impacts.

[0058] Specifically, during the rotation of display screen 200, first gasket 150 reduces direct friction between connector 120 and elastic member 130, preventing scratches on both surfaces. Second gasket 160 performs a similar function, alleviating pressure between elastic member 130 and retaining member 140, ensuring that elastic member 130 can freely expand and contract without becoming stuck. Furthermore, the provision of first and second gaskets 150, 160 compensates for manufacturing tolerances, ensuring a tighter and smoother fit between components.

[0059] In some embodiments, gasket materials with different properties can be selected based on the requirements of specific application scenarios. For example, a robot 10 used in high-temperature environments can use a silicone gasket with excellent heat resistance; for equipment requiring high-precision positioning, a PTFE (polytetrafluoroethylene) gasket with a low friction coefficient can be used. Furthermore, gaskets can be designed to be replaceable for easy maintenance by the user.

[0060] See also Figures 1 to 3 The second aspect of the present invention further provides a robot 10, comprising a main body, a display screen 200, and a rotating shaft 110 assembly 100 as described in any of the above embodiments. The rotating shaft 110 assembly 100 is used to mount and adjust the angle of the display screen 200. The second connecting portion 122 of the rotating shaft 110 assembly 100 is connected to the main body, and the rotating shaft 110 is connected to the display screen 200. The display screen 200 can move relative to the main body to adjust its tilt angle relative to the main body, ensuring that the displayed content can face the user or operator, thereby improving the user experience.

[0061] Specifically, when the user needs to change the angle of display screen 200, they simply gently rotate it. The shaft 110 will then rotate relative to the connector 120, while the elastic member 130 provides appropriate resistance, keeping the display screen 200 stable in its new position. The function of the stopper 140 is to prevent the elastic member 130 from slipping off the shaft 110, ensuring the safety of the entire system. Furthermore, the presence of the first gasket 150 and the second gasket 160 reduces friction between the components, increases service life, and reduces noise. This not only provides flexible angle adjustment for the display screen 200 but also enhances the human-machine interaction experience of the robot 10.

[0062] See also Figure 2 In some embodiments, the second connecting portion 122 is provided with a first connecting hole 1223, and the robot 10 further includes a fastener. The main body is provided with a first mounting hole connected to the first connecting hole 1223, and the fastener is passed through the first connecting hole 1223 and the first mounting hole, thereby fixing the second connecting portion 122 to the main body. In addition, the side of the second connecting portion 122 facing away from the first connecting portion 121 abuts against the main body, ensuring close contact between the two. In addition, the second connecting portion 122 is provided with a first positioning hole 1224, which is located on the side of the connecting hole away from the first connecting portion 121, and the main body is provided with a first positioning member, which is configured to be inserted into the first positioning hole 1224 to ensure the correct assembly position.

[0063] Specifically, through the coordinated use of the first connecting hole 1223 and the first mounting hole, the fastener securely connects the second connecting portion 122 to the main body. The first positioning hole 1224 mates with the first positioning member on the main body to ensure precise alignment of the components during assembly, preventing functional failure or cosmetic defects caused by misalignment. Fasteners (including but not limited to screws and bolts) are inserted through the first connecting hole 1223 and the first mounting hole and tightened to form a mechanical connection, firmly securing the second connecting portion 122 to the main body. The insertion of the first positioning member into the first positioning hole 1224 provides a guide for assembly, ensuring that each component is accurately and securely installed. This design simplifies the assembly process and improves production efficiency, while also enhancing product reliability and consistency and improving the overall appearance quality of the product. This design helps reduce manufacturing costs and improve market competitiveness, particularly for mass-produced robot 10 products. Furthermore, when repairs or component replacements are required, users can easily disassemble and reinstall the relevant components, enhancing product maintainability.

[0064] See also Figure 2 and Figure 4In some embodiments, the rotating shaft 110 has a first connecting surface 111 and a second connecting surface 112 disposed opposite each other. The first connecting surface 111 abuts the display screen 200, and both connecting surfaces are located at the end of the rotating shaft 110 away from the connector 120. Furthermore, the robot 10 includes a fastener for securely securing the rotating shaft 110 to the display screen 200. The first connecting surface 111 of the rotating shaft 110 directly contacts and supports the back surface of the display screen 200, ensuring a tight fit between the two. The first connecting surface 111 provides a larger contact area, ensuring a more stable and reliable connection. Furthermore, the rotating shaft 110 is provided with a second connecting hole 113 extending through the first and second connecting surfaces 111 and 112, while the display screen 200 is provided with a second mounting hole 210 at a corresponding location. Fasteners (including but not limited to screws and bolts) are inserted through the second connecting hole 113 and the second mounting hole 210 to achieve final securement. This not only effectively prevents unnecessary displacement of the display screen 200 relative to the hinge 110, but also allows it to withstand significant external torque, ensuring stable angle adjustment under all circumstances. The presence of the first connecting surface 111 and the second connecting surface 112 creates a smoother connection between the hinge 110 and the display screen 200, reducing stress concentration caused by uneven surfaces and improving the durability of the overall structure.

[0065] In some embodiments, the display screen 200 is provided with a second positioning member 220, and the rotating shaft 110 is provided with a second positioning hole 114, wherein the second positioning hole 114 passes through the first connecting surface 111 and the second connecting surface 112, and the second positioning member 220 is configured to be able to be passed through the second positioning hole 114, thereby making the assembly of the rotating shaft 110 assembly 100 and the display screen 200 more convenient and accurate.

[0066] In some embodiments, cushioning material or elastic gaskets can be inserted between the first connecting surface 111 of the rotating shaft 110 and the display screen 200 to absorb vibration and impact, protecting sensitive electronic components from damage. For robots 10 with specialized applications (such as outdoor equipment), fasteners with a higher waterproof and dustproof rating can be used to enhance environmental adaptability. Furthermore, if more precise angle adjustment is required, a fine-tuning mechanism can be integrated into the rotating shaft 110, allowing the user to finely adjust the angle of the display screen 200 within a certain range.

[0067] See also Figure 3In some embodiments, the display screen 200 is provided with a clearance hole 230. This clearance hole 230 is configured to accommodate the rotating shaft 110, ensuring that the rotating shaft 110 can smoothly extend from the side of the display screen 200 without affecting the appearance design. In other words, the clearance hole 230 provides the necessary passage for the rotating shaft 110. Along the thickness direction of the display screen 200, the distance from the axis of the clearance hole 230 to the side of the display screen 200 facing away from the display surface 240 is greater than the distance from the display surface 240 to the axis of the clearance hole 230. This ensures smooth rotation of the display screen 200 while preventing the display screen 200 from protruding from the surface of the robot 10, thereby preventing the display screen 200 from being scratched and damaged, and also improving the product's aesthetics.

[0068] The shape and size of the clearance hole 230 match the shaft 110, allowing the shaft 110 to pass through without interference. The design of the clearance hole 230 allows the shaft 110 to have sufficient space to extend inside the display screen 200. In addition, the edges of the clearance hole 230 can be chamfered to prevent sharp edges from damaging the wires or other components inside the display screen 200.

[0069] In some embodiments, the avoidance hole 230 can be designed to pass through the side of the display screen 200 in the direction from the display surface 240 to the shaft 110, that is, the avoidance groove is in the shape of a groove passing through the display screen 200, so as to improve the assembly convenience of the shaft 110 assembly 100 and the display screen 200, and at the same time avoid the smoothness of the rotation of the display screen 200 being affected by the friction of the shaft 110 during the rotation of the display screen 200, thereby ensuring the user experience.

[0070] In order to further balance the force on the hinge 110 assembly 100 and eliminate the influence of stress on the hinge 110, in some embodiments, a hinge 110 assembly 100 described in any of the above embodiments is respectively provided at two opposite ends of the display screen 200, wherein the first connecting piece 1221 is located on one side of the display surface 240 of the display screen 200, and the second connecting piece 1222 is located on the side of the display screen 200 opposite to the display surface 240.

[0071] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0072] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.
