Description

Technical Field

[0001] The present invention relates to the technical field of encoders, and in particular to a rotating wheel structure, an encoder, a computer device and an apparatus. Background Art

[0002] An encoder is a device that converts displacement into electrical signals and outputs them. For example, a mouse is provided with a scroll wheel, and users can scroll the scroll wheel to browse web pages or documents. Specifically, an encoder is provided inside the mouse, and a rotating shaft is connected to the scroll wheel. The rotating shaft moves with the scroll wheel, and one end of the rotating shaft is plugged into the encoder to drive the rotating wheel inside the encoder to rotate. The components in the encoder convert the rotation of the scroll wheel into electrical signals; a positioning spring is provided inside the encoder, and a tooth surface is provided on the rotating wheel. Through the action of the positioning spring and the tooth surface, the scroll wheel presents a segmented damping feeling when rolling, so as to improve the controllability and user experience when operating the scroll wheel.

[0003] In the prior art, the rotating wheel is a single hard structure made of a single material plastic. The rotating wheel is provided with a socket adapted to the rotating shaft. The rotating shaft drives the rotating wheel to rotate through the socket. This structure has the following defects:

[0004] In order to facilitate the insertion of the rotating shaft into the socket, a clearance fit is set between the two. When the rotating wheel rotates, the positioning spring and the tooth surface will produce an obvious impact sound when they rotate relative to each other. This impact sound will be transmitted through the gap between the rotating shaft and the socket, causing the user to have obvious noise when operating the scroll wheel. This noise can easily penetrate the tranquility in a quiet night or in a work environment that requires high concentration, and become a noise source that disturbs people's hearts, posing a potential threat to the user's concentration and work efficiency. In order to reduce this noise, the practice of the prior art is to set the gap between the rotating shaft and the socket as small as possible to reduce the transmission of noise. However, this will bring another problem: the scroll wheel on the mouse is usually also set to be able to be pressed down. For example, the user can press down the scroll wheel and move the mouse to move the web page up, down, left, and right, etc. If the gap between the rotating shaft and the socket is too small, it will affect the pressing operation of the scroll wheel, resulting in more effort when the finger presses down the mouse wheel, or a local heavy phenomenon, resulting in a poor user experience. Therefore, in the prior art, the gap between the rotating shaft and the socket cannot be set too large, nor can it be set too small. The noise reduction problem when the roller rolls and the hand feel problem when the roller is pressed down are contradictory to each other and have not yet been well balanced and solved.

[0005] Therefore, it is necessary to improve and optimize the existing encoders. Summary of the invention

[0006] The present invention aims to solve at least one of the problems in the prior art. To this end, the present invention provides a wheel structure, an encoder, a computer device and an apparatus, which take into account the noise reduction problem when the wheel rolls and the hand feel problem when the wheel is pressed down, and provide a good user experience.

DETAILED DESCRIPTION

[0042] To make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments described below can be combined with each other arbitrarily without conflict.

[0043] Many different implementations or examples are provided below for implementing the structure of the present invention.

[0044] See also Figure 1-Figure 17 The embodiment of the first aspect of the present invention provides a wheel structure, comprising: a first wheel body 1, wherein the first wheel 1 is provided with a tooth surface 11; a second wheel body 2, which is combined with the first wheel body 1, wherein the first wheel body 1 or the second wheel body 2 is provided with a first plug hole 21, wherein the first plug hole 21 is used to adapt to the following rotating shaft 10, see Figure 1 and Figure 2 As shown, in this embodiment, the first socket 21 is arranged on the second wheel body 2; the silencer 3 is arranged between the first wheel body 1 and the second wheel body 2, and the silencer 3 is provided with a second socket 31, and the second socket 31 is used to adapt to the following rotating shaft 10, and the second socket 31 corresponds to the position of the first socket 21, that is, the following rotating shaft 10 can pass through the first socket 21 and the second socket 31 at the same time; the silencer 3 is an elastic material, and the aperture of the second socket 31 is smaller than the aperture of the first socket 21. In this embodiment, the silencer 3 is silicone or rubber, and the first wheel body 1 and the second wheel body 2 are plastic parts.

[0045] Regarding the combination mode between the first wheel body 1, the second wheel body 2 and the muffler 3, in some embodiments of the present invention, see Figure 2 As shown, a fixing pin 12 is provided on the first wheel body 1, and a fixing hole 22 is provided on the second wheel body 2. The fixing pin 12 is inserted into the fixing hole 22 to realize the combination and fixation of the first wheel body 1 and the second wheel body 2. The muffler 3, the first wheel body 1, and the second wheel body 2 are separately provided, and the muffler 3 is clamped and fixed by the first wheel body 1 and the second wheel body 2; in other embodiments, the muffler 3 is injection molded as one with the first wheel body 1 or the second wheel body 2, for example, after the muffler 3 is injection molded as one with the first wheel body 1 by secondary injection molding, the first wheel body 1 and the second wheel body 2 are connected by the fixing pin and the fixing hole; in other embodiments, the first wheel body 1, the second wheel body 2 and the muffler 3 are injection molded as one, for example, by multiple injection molding.

[0046] See Figure 2 and Figure 5-Figure 8As shown, in some embodiments of the present invention, the muffler 3 is tooth-shaped, polygonal or circular, and a slot 13 is provided on the first wheel body 1 and / or the second wheel body 2, and the slot 13 is adapted to the muffler 3, and the muffler 3 is arranged in the slot 13. By setting the muffler 3 to be tooth-shaped or polygonal and installing it in the slot 13, the muffler 3 will not rotate relative to the first wheel body 1 and the second wheel body 2, thereby ensuring the relative fixation of the positions of the three. When the rotational force of the rotating shaft 10 is not required to be transmitted through the muffler 3, the muffler 3 can also be set to a circle. When the muffler 3 is injection molded together with the first wheel body 1 and / or the second wheel body 2, even if the muffler 3 is set to a circle, the rotating shaft 10 can drive the rotating wheel structure to rotate through the muffler 3.

[0047] See Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the second socket 31 is coaxially arranged with the first socket 21, and the hole shape of the first socket 21 and the second socket 31 is circular or polygonal. The hole shape of the first socket 21 and the second socket 31 is the same, and both are hexagonal in this embodiment. The hole shapes of the first socket 21 and the second socket 31 can also be different, for example, the first socket 21 is hexagonal and the second socket 31 is circular. It can be understood that the first socket 21 can be used to cooperate with the rotating shaft 10 described below to drive the rotating wheel structure to rotate, and can also be used to cooperate with the rotating shaft 10 described below to drive the rotating wheel structure to rotate separately or simultaneously through the second socket 31.

[0048] See Fig.17 and Fig.18 As shown, in some embodiments of the present invention, the first plug hole 21 has an inclined hole wall arranged obliquely along its axial direction, and the hole diameter of the inclined hole wall close to the second plug hole 31 is smaller than the hole diameter far from the second plug hole 31. This structure fully considers the problem of deviation from the central axis when the shaft is pressed down, so that the hole wall shape of the first plug hole 21 can better adapt to the pressing of the shaft 10, thereby, the pressing of the roller 9 will become easier. It can be understood that the hole wall of the first plug hole 21 can be set as an inclined hole wall (such as Fig.18 As shown), a small section can also be set as a straight wall and the rest as an inclined hole wall (as shown Fig.17 shown).

[0049] See Figure 9-12As shown, the second aspect of the present invention provides an encoder, including a shell 4, the shell 4 includes a base 41 made of plastic material and a shell 42 made of metal material, a positioning spring piece 5 and a switching piece 6 are arranged in the shell 4, the positioning spring piece 5 is fixedly connected to the shell 4, specifically, a plurality of convex columns 43 are arranged on the base 41, the positioning spring piece 5 is sleeved on the convex columns 43, and also includes the rotating wheel structure described in any one of the embodiments of the first aspect, the rotating wheel structure is rotatably connected to the shell 4, specifically, hinge shafts 14 are respectively arranged at both ends of the rotating wheel structure, hinge holes 44 are respectively arranged on the base 41 and the shell 42, and the rotating wheel structure is implemented by the cooperation of the hinge shaft 14 and the hinge hole 44. Now the rotation connection is made, the positioning spring piece 5 abuts against the tooth surface 11. Specifically, the positioning spring piece 5 has a pin 51, and the pin 51 abuts against the tooth surface 11. When the rotating wheel structure rotates, the pin 51 switches between different tooth grooves on the tooth surface, thereby providing a segmented damping feeling for the roller. The switching piece 6 is fixed on the rotating wheel and can rotate with the rotating wheel. In this embodiment, the switching piece 6 is sleeved on the fixing pin 12 and is located on the end face of the second wheel body 2. Thus, the rotation of the rotating wheel will drive the switching piece 6 to rotate. A conductive terminal 7 is connected to the base 41, and the switching piece 6 abuts against the conductive terminal 7. The rotation of the switching piece 6 on the conductive terminal 7 will form an electrical signal, so that the physical rotation of the roller can be converted into a control signal.

[0050] See Fig.11 As shown, in some embodiments of the present invention, a vibration-damping elastic pad 8 is arranged between the positioning spring piece 5 and the shell 42. The vibration-damping elastic pad 8 can be made of silicone. The vibration-damping elastic pad 8 isolates the positioning spring piece 5 from the shell 42 to avoid direct contact between the two. Therefore, when the roller rolls, the vibration of the positioning spring piece 5 will be absorbed by the vibration-damping elastic pad 8, and the vibration will not be transmitted to the shell 42, thereby avoiding the noise generated between the positioning spring piece 5 and the tooth surface 11 from being transmitted to the outside through the shell 42, further reducing or eliminating the noise appearance when the roller rolls, making the roller quieter when rolling.

[0051] See Figure 15-18 As shown, a third aspect of the present invention provides a computer device, which can specifically be a mouse or a keyboard. The mouse or the keyboard includes the encoder described in any one of the embodiments of the second aspect, and also includes a roller 9, and the roller 9 is connected to a rotating shaft 10. In this embodiment, the rotating shaft 10 is integrally formed on the roller 9, and the rotating shaft 10 is linked with the roller 9. The rotating shaft 10 is inserted into the first socket 21 and the second socket 31, wherein at least a portion of the first socket 21 is gap-fitted with the rotating shaft 10, and the second socket 31 is covered on the rotating shaft, and the second socket 31 is interference-fitted with the rotating shaft 10.

[0052] See Fig.17and Fig.18 As shown, in some embodiments of the present invention, the first plug hole 21 has an inclined hole wall inclined along its axial direction, the aperture of the inclined hole wall close to the second plug hole 31 is smaller than the aperture away from the second plug hole 31, and the first plug hole 21 has a maximum aperture and a minimum aperture, wherein the first plug hole 21 has a clearance fit or an interference fit with the rotating shaft 10 at the minimum aperture, and the minimum aperture of the first plug hole 21 can be an inclined hole wall or a straight wall. For details, see Fig.17 As shown, the first plug hole 21 is loosely matched with the rotating shaft 10; see Fig.18 As shown, the first insertion hole 21 has an interference fit with the rotating shaft 10 near the muffler 3 , and has a clearance fit with the rotating shaft 10 at other positions. When the entire hole wall of the first plug hole 21 is loosely matched with the rotating shaft 10, the rotating shaft 10 needs to rotate a certain angle (of course, this angle is small) before it can abut against the hole wall of the first plug hole 21. The rotating shaft 10 continues to rotate, and the rotating shaft 10 will drive the rotating wheel to rotate, or the rotating shaft 10 needs to rotate a certain angle (of course, this angle is small) so that the deformation force of the muffler 3 drives the rotating wheel to rotate. Therefore, there is a certain hysteresis between the rotation of the rotating wheel and the rotation of the rotating shaft 10. The first plug hole 21 is interference fit with the rotating shaft 10 at the minimum aperture (the interference amount is very small, about 1 thread), so that the rotation of the rotating shaft 10 can be transmitted to the rotating wheel through the interference fit in time, and the linkage between the rotating wheel and the rotating shaft is timely, avoiding the hysteresis problem between the two. Since the first plug hole 21 is an inclined hole, the interference fit position between the first plug hole 21 and the rotating shaft 10 at the minimum aperture is point or line contact, which will not affect the smooth downward pressure of the rotating shaft 10. It is understandable that the interference fit between the first plug hole 21 and the shaft 10 at the minimum aperture is very small and is point or line contact. In addition, the shaft 10 and the hole wall of the first plug hole 21 are generally made of hard material. The interference fit at the minimum aperture alone cannot effectively block the propagation of noise (the sealing between the two is limited). Therefore, the provision of the silencer 3 made of elastic material is necessary.

[0053] The fourth aspect of the present invention also provides an apparatus, including a computer, and also including the computer device described in the third aspect of the embodiment. The computer device can be electrically connected to the computer, and the electrical connection can be a wired connection or a wireless connection.

[0054] See Fig.17 , Fig.18 As shown, the working principle of the embodiment of the present invention is as follows: Fig.18After the roller structure in the encoder is rotatably installed in the housing 4, the cooperation between the hinge shaft 14 on the roller structure and the hinge hole 44 on the housing 4 basically reaches the sealing level, so that the roller structure is sealed and installed in the housing 4 (the same is true in the prior art). Therefore, the noise generated when the positioning spring piece 5 and the tooth surface 11 work is mainly transmitted to the outside through the gap between the first plug hole 21 and the rotating shaft 10 on the roller structure in the prior art. In the embodiment of the present invention, when the roller 9 rotates, the impact sound waves generated by the relative movement of the positioning spring piece 5 and the tooth surface 11 enter the interior of the rotating wheel structure. Since the silencer 3 is made of elastic material, the second socket 31 on the silencer 3 is interference fit with the rotating shaft 10, so that there is no gap or space between the silencer 3 and the rotating shaft 10 to allow the impact sound waves to be transmitted to the side where the roller 9 is located. The impact sound waves are blocked by the silencer 3, which greatly reduces or eliminates the noise when the roller rolls. In view of the fact that the silencer 3 has reduced or eliminated the noise, the design between the first socket 21 and the rotating shaft 10 does not need to consider the noise reduction problem and the gap can be set larger. Therefore, the larger gap between the two provides an avoidance space for the linkage downward pressure of the rotating shaft 10 when the roller 9 is pressed down, making it easy and relaxed to press the roller down, greatly improving the feel of the roller when it is pressed down. The embodiment of the present invention, through a clever structure, well takes into account the noise reduction problem when the roller rolls and the feel problem when the roller is pressed down, improves the user's experience, and has a simple and clever structure, easy implementation, and low cost.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
