[0045] Please refer to Figures 1 to 5 , the present invention provides a mouse scroll wheel 10.
[0046] In an embodiment of the present invention, the mouse scroll wheel 10 includes a mounting base 111, a rolling wheel 13, a circuit board 15, and an optical code disc 16. Among them, the rolling wheel 13 is rotatably arranged on the mounting base 111, and a receiving cavity is formed by enclosing with the mounting base 111; the circuit board 15 is connected to the mounting base 111 and is located in the receiving cavity. The circuit board 15 is provided with a light emitter 151, a first light receiver 153, and a second light receiver 155. A first optical path is formed by conduction between the first light receiver 153 and the light emitter 151, and a second optical path is formed by conduction between the second light receiver 155 and the light emitter 151; the optical code disc 16 is connected to the rolling wheel 13 and is located in the receiving cavity. The axis of the optical code disc 16 is also on the same straight line as the axis of the rolling wheel 13. When the rolling wheel 13 rotates relative to the mounting base 111, the optical code disc 16 is driven by the rolling wheel 13 and can block the first optical path and the second optical path successively along the rotation direction of the rolling wheel 13.
[0047] In an embodiment of the present invention, the mounting base 111 can be used to mount and carry the rolling wheel 13, so that only the rolling wheel 13 of the mouse wheel 10 can rotate, while the mounting base 111 can be directly limited and fixed relative to the mouse housing 30. At this time, compared with the prior art where the mouse wheel 10 and the encoder are independently and separately arranged, in order to enable the encoder to be driven by the mouse wheel 10 so that the entire mouse wheel 10 can be rotatably connected to the mouse housing 30, the mouse wheel 10 in the present application is directly limited and fixed to the mouse housing 30 through the mounting base 111, which can be simpler than the connection method in the prior art where the entire mouse wheel 10 is rotatably connected to the mouse housing 30, thereby improving the convenience of mounting the mouse wheel 10 on the mouse housing 30. Among them, the material of the mounting base 111 can be a plastic material, so that the mass of the mounting base 111 is relatively light, which is beneficial to reducing the overall volume of the mouse 100, and further facilitating the use by the user. Of course, the present application is not limited to this. In other embodiments, the material of the mounting base 111 can also be a metal material, so that the mounting base 111 has relatively strong strength, which is beneficial to extending the service life of the mounting base 111. The rolling wheel 13 can be driven by the user when performing some command inputs (such as: scrolling up, scrolling down, going to the previous page, going to the next page, zooming in or zooming out, etc.), so that it can rotate forward or backward relative to the mounting base 111 accordingly. The circuit board 15 can be used to mount the light emitter 151, the first light receiver 153, and the second light receiver 155, and can detect the change in the optical signal of the first optical path formed between the light emitter 151 and the first light receiver 153, as well as the change in the optical signal of the second optical path formed between the light emitter 151 and the second light receiver 155. Specifically, when the optical code disc 16 is driven to rotate forward by the rolling wheel, the circuit board 15 can first detect the change in the first optical path and recognize that the rolling wheel 13 is being driven forward by the user for corresponding command input. The specific forward movement distance of the mouse wheel 10 can be calculated according to the number of conversions of conduction and blocking of the first light receiver 153 during the process of the optical code disc 16 being driven to rotate forward by the rolling wheel. Similarly, when the optical code disc 16 is driven to rotate backward by the rolling wheel, the circuit board 15 can first detect the change in the second optical path and recognize that the rolling wheel 13 is being driven backward by the user for corresponding command input. The specific backward movement distance of the mouse wheel 10 can be calculated according to the number of conversions of conduction and blocking of the second light receiver 155 during the process of the optical code disc 16 being driven to rotate backward by the rolling wheel. In addition, the light emitter 151, the first light receiver 153, and the second light receiver 155 can be fixed to the circuit board 15 by soldering, so as to achieve electrical connection while realizing mechanical connection. Of course, the present application is not limited to this. In other embodiments, the light emitter 151, the first light receiver 153, and the second light receiver 155 can also be adhered to the circuit board 15 by glue.The first optical receiver 153 and the second optical receiver 155 can be independently arranged, that is, the two receiving chips are independently packaged. Of course, the first optical receiver 153 and the second optical receiver 155 can also be integrally arranged, that is, the two receiving chips are integrally packaged. The optical transmitter 151 can be an LED light source, so that it can emit relatively bright light for easy reception by the first optical receiver 153 and the second optical receiver 155, and at the same time, it can be relatively energy-saving. Moreover, the LED light source also has the advantage of relatively small volume, which enables it to be easily installed on the circuit board 15. Further, the light emitted by the optical transmitter 151 can be visible light or invisible light. Of course, it should be noted that this application is not limited thereto. In other embodiments, the optical transmitter 151 can also be an ordinary incandescent light source, as long as it can emit corresponding optical signals for the first optical receiver 153 and the second optical receiver 155 to receive. The optical code disk 16 can be used to rotate synchronously with the rolling wheel 13, and when rotating, it can block the first optical path and the second optical path successively according to the rotation direction (for example: block the first optical path first and then the second optical path according to the forward rotation direction of the rolling wheel 13; block the second optical path first and then the first optical path according to the backward rotation direction of the rolling wheel 13).
[0048] When the mouse wheel 10 of the technical solution of the present invention is in use, when the scroll wheel 13 is driven by the user to rotate forward, the scroll wheel 13 can drive the optical code disk 16 connected thereto to rotate synchronously. At this time, the optical code disk 16 can first block the first optical path formed between the optical emitter 151 and the first optical receiver 153. Then, through the circuit board 15, it can be detected that the optical signal of the first optical path changes first, and then the forward rolling of the scroll wheel 13 can be recognized, so that the mouse 100 can complete the corresponding command input work according to the forward rolling of the scroll wheel 13. When the scroll wheel 13 is driven by the user to rotate backward, the scroll wheel 13 can drive the optical code disk 16 connected thereto to rotate synchronously. At this time, the optical code disk 16 can first block the second optical path formed between the optical emitter 151 and the second optical receiver 155. Then, through the circuit board 15, it can be detected that the optical signal of the second optical path changes first, and then the backward rolling of the scroll wheel 13 can be recognized, so that the mouse 100 can complete the corresponding command input work according to the backward rolling of the scroll wheel 13. Moreover, since the circuit board 15 and the optical code disk 16 in this solution are both arranged in the accommodating cavity enclosed by the scroll wheel 13 and the mounting seat 111 of the mouse wheel 10, that is, the encoder is set on the mouse wheel 10, so that the two are relatively integrated. Thus, compared with the prior art in which the mouse wheel 10 and the encoder are both independently arranged separately, which makes the two occupy a relatively large space on the mouse 100, resulting in the overall volume of the mouse 100 needing to be set relatively large. In this solution, the mouse wheel 10 is integrated with the optical code disk 16 inside it, so that the two are distributed more compactly, reducing the space occupied by it, and making the overall volume of the mouse 100 can be set relatively small and convenient for the user to hold, thus facilitating the improvement of the convenience of using the mouse 100. Moreover, arranging the circuit board 15, the optical emitter 151, the first optical receiver 153, the second optical receiver 155, and the optical code disk 16 in the accommodating cavity formed by enclosing the scroll wheel 13 and the mounting seat 111 of the mouse wheel 10 can make the installation of the optical emitter 151, the first optical receiver 153, the second optical receiver 155, and the optical code disk 16 relatively sealed, reducing the influence of external dust on them, thus facilitating the guarantee of the working accuracy and service life of the optical emitter 151, the first optical receiver 153, the second optical receiver 155, and the optical code disk 16.
[0049] Please refer to Figure 3 , Figure 4 and Figure 5, in an embodiment of the present invention, the mounting base 111 includes two support bases 111 and a connecting shaft 117. The two support bases 111 are arranged at a relative interval; the opposite ends of the connecting shaft 117 are respectively connected to the two support bases 111; the rolling wheel 13 is rotatably sleeved on the connecting shaft 117, and a receiving groove 131 is recessed on the side wall surface facing one of the two support bases 111. The bottom wall of the receiving groove 131 is penetrated by the connecting shaft 117, and together with the support base 111 of the two support bases 111 facing the bottom wall of the receiving groove 131, a receiving cavity is formed; the circuit board 15 is connected to the support base 111 of the two support bases 111 facing the bottom wall of the receiving groove 131.
[0050] It can be understood that the mounting base 111 can be connected to the mouse housing 30 through the two support bases 111, so that the mouse scroll wheel 10 has a connection relationship with the mouse housing 30 at both opposite ends. In this way, the connection strength between the mounting base 111 and the mouse housing 30 can be enhanced, thereby improving the stability of the mouse scroll wheel 10 during operation. At the same time, the receiving cavity is formed by enclosing the receiving groove 131 of the rolling wheel 13 and the support base 111 of the two support bases 111 facing the bottom wall of the receiving groove 131. After a groove is opened on the side wall surface of the rolling wheel 13 and assembled with the support base 111 to form an integral body, the receiving cavity can be formed by enclosing, thereby improving the convenience of processing and forming the receiving cavity. Of course, it should be noted that the present application is not limited to this. In other embodiments, the mounting base 111 may also only include one support base 111 and a connecting shaft 117. At this time, the receiving cavity may be formed by enclosing the receiving groove 131 recessed on the side wall surface of the rolling wheel 13 and the support base 111; or, a groove may be recessed inward on the inner circumferential surface of the rolling wheel 13, and the receiving cavity is formed by enclosing the side circumferential surface of the groove and the connecting shaft 117. In addition, in order to increase the receiving capacity of the receiving cavity, a groove may be recessed on the surface of the support base 111 facing the bottom wall of the receiving groove 131, so as to form the receiving cavity by enclosing the groove and the receiving groove 131. In order to facilitate the connection between the two support bases 111 and the mouse housing 30, the support base 111 may be non-circular (for example: it may be approximately square, rectangular or oval, etc.). At this time, two card slots are provided on the mouse housing 30, and the two support bases 111 are respectively clamped in the two card slots.
[0051] Please refer to Figure 5, in an embodiment of the present invention, the optical code disk 16 is provided with a plurality of light-transmitting holes 161. The plurality of light-transmitting holes 161 penetrate through the side wall surfaces of the optical code disk 16 facing and departing from the bottom wall of the accommodation groove 131, and are arranged at intervals along the circumferential direction of the optical code disk 16. It is defined that the optical code disk 16 has opposite sides facing and departing from the bottom wall of the accommodation groove 131. The light emitter 151 is located on one of the opposite sides of the optical code disk 16, and the first light receiver 153 and the second light receiver 155 are located on the other of the opposite sides of the optical code disk 16. The light signal emitted by the light emitter 151 forms a first optical path through the light-transmitting hole 161 to the first light receiver 153, and the light signal emitted by the light emitter 151 forms a second optical path through the light-transmitting hole 161 to the second light receiver 155.
[0052] It can be understood that the optical code disk 16 conducts the first optical path and the second optical path through the light-transmitting holes 161. During the rotation of the optical code disk 16 itself, the light-transmitting holes 161 arranged at intervals can block the first optical path and the second optical path successively, causing the light signal received by the optical receiver to change. At this time, it is not necessary to additionally provide a light-blocking member on the optical code disk 16 to block the first optical path and the second optical path during its rotation. In this way, the structure of the optical code disk 16 is simplified, which is conducive to reducing the manufacturing cost of the mouse scroll wheel 10. At the same time, with such a setting, the optical code disk 16 can be relatively centered in the accommodation cavity, and the circuit board 15 can be located below the optical code disk 16. The light emitter 151, the first optical receiver 153, and the second optical receiver 155 can be respectively on opposite sides of the optical code disk 16. At this time, their distribution is relatively compact, which is conducive to reducing the space occupation without setting the accommodation cavity to be relatively large, and further conducive to reducing the overall volume of the mouse scroll wheel 10. Among them, the light-transmitting hole 161 can be a rectangular hole to make its shape regular and facilitate processing and manufacturing. Of course, the light-transmitting hole 161 can also be a square hole, a circular hole, or other shaped holes, etc. In addition, it should be noted that this application is not limited to this. In another embodiment of the present invention, the optical code disk 16 can be provided with a plurality of first reflecting surfaces. The plurality of first reflecting surfaces are all arranged on the circumferential surface of the side wall of the optical code disk 16 facing the groove side wall of the accommodation groove 131 and are arranged at intervals along the circumferential direction of the optical code disk 16. The support seat 111 facing the bottom wall of the accommodation groove 131 is provided with a second reflecting surface on the side wall surface in the accommodation cavity. The second reflecting surface is located above the first optical receiver 153 and the second optical receiver 155. The light signal emitted by the light emitter 151 forms the first optical path to the first optical receiver 153 through the first reflecting surface and the second reflecting surface. The light signal emitted by the light emitter 151 forms the second optical path to the second optical receiver 155 through the first reflecting surface and the second reflecting surface. At this time, the light emitter 151 can be arranged below the first reflecting surface, that is, below the optical code disk 16; and the first optical receiver 153 and the second optical receiver 155 can be located on one side of the optical code disk 16. Or, in another embodiment of the present invention, the optical code disk 16 is additionally connected with a plurality of light-blocking members. During the rotation of the optical code disk 16, the plurality of light-blocking members can directly pass between the light emitter 151, the first optical receiver 153, and the second optical receiver 155 in sequence. That is, when the optical code disk 16 rotates, the light-blocking members on the optical code disk 16 block the optical path between the light emitter 151, the first optical receiver 153, and the second optical receiver 155 at intervals.
[0053] Please refer to Figure 3 、 Figure 4 and Figure 5, in an embodiment of the present invention, the rolling wheel 13 is provided with an installation cylinder 133 on the bottom wall of the accommodation groove 131. The installation cylinder 133 extends in the direction towards the notch of the accommodation groove 131. The installation cylinder 133 is sleeved on the connecting shaft 117, and the optical code disk 16 is sleeved on the installation cylinder 133.
[0054] It can be understood that the optical code disk 16 can be directly sleeved on the installation cylinder 133 for installation. At this time, an installation hole adapted to the installation cylinder 133 can be provided on the optical code disk 16. In this way, the structures and connection processes of both are relatively simple, which is beneficial to improving the convenience of installing the optical code disk 16. Of course, the present application is not limited to this. In other embodiments, it is also possible that a plurality of connecting rods protrude from the side wall surface of the optical code disk 16 facing the bottom wall of the accommodation groove 131, and the ends of the plurality of connecting rods away from the optical code disk 16 are connected to the bottom wall of the accommodation groove 131.
[0055] Please refer to Figure 4 , Figure 5 and Figure 6 , in an embodiment of the present invention, a first boss 163 is provided on the surface of the optical code disk 16 facing away from the bottom wall of the accommodation groove 131. The first boss 163 is annular and surrounds the installation cylinder 133. A plurality of limiting grooves 165 are provided on the outer side wall surface of the first boss 163; the mouse scroll wheel 10 further includes an elastic member 17. The elastic member 17 has an elastic arm 171. The elastic arm 171 abuts against the outer circumferential surface of the first boss 163 and protrudes outwardly from the optical code disk 16 to form a limiting portion 173. The limiting portion 173 is embedded in the limiting groove 165.
[0056] It can be understood that through the abutment of the limiting portion 173 of the elastic arm 171 of the elastic member 17 and the limiting groove 165 of the first boss 163 (during the rotation of the encoder driven by the mouse scroll wheel 10, the limiting portion 173 of the elastic arm 171 is successively embedded in the limiting groove 165 of the first boss 163), when the optical code disk 16 is driven to rotate by the rolling wheel 13, a certain resistance can be generated to produce a sense of touch. In this way, it is convenient for the user to control the rotation speed of the driving of the rolling wheel 13, that is, to reduce the influence of the rolling wheel 13 rolling too fast on the instruction input effect (such as moving up and down too fast, turning pages too fast, or zooming in and out too fast). Further, please refer to Figure 4 , Figure 6 and Figure 7, the elastic member 17 may further include a main body section 175 and a fixing arm 177. Among them, the main body section 175 may be sleeved on the mounting post 115 protruding from the support base 111 facing the bottom wall of the accommodation groove 131. The main body section 175 has two opposite ends. The elastic arm 171 is connected to one end of the main body section 175, and the fixing arm 177 is connected to the other end of the main body section 175. And the other end of the fixing arm 177 away from the main body section 175 may be inserted into the support base 111 facing the bottom wall of the accommodation groove 131.
[0057] Please refer to Figure 4 , Figure 5 and Figure 6 , in an embodiment of the present invention, it is defined that the mouse scroll wheel 10 has an up-down direction, and the elastic arm 171 of the elastic member 17 is located below the first boss 163; there is a gap between the top wall of the barrel of the mounting cylinder 133 and the connecting shaft 117, so that the rolling wheel 13 can move up and down relative to the two support bases 111, and when the rolling wheel 13 moves down relative to the two support bases 111, the optical code disk 16 is driven by the rolling wheel 13 to block the first optical path and the second optical path simultaneously.
[0058] It can be understood that by driving the optical code disk 16 by the rolling wheel 13 to block the first optical path and the second optical path simultaneously, and then through the circuit board 15, the change of the optical signal occurring simultaneously in the first optical path and the second optical path can be detected, and then the downward movement generated by the user pressing the rolling wheel 13 can be recognized, so that the mouse 100 can complete the corresponding command input work according to the operation of the user pressing the rolling wheel 13. In this way, the optical code disk 16 can not only recognize the forward and backward rotation of the mouse scroll wheel 10, but also recognize the pressing determination of the mouse scroll wheel 10, thereby making the use function of the mouse scroll wheel 10 more diversified, and thus improving the practicability of the use of the mouse scroll wheel 10. After the rolling wheel 13 is pressed and lowered by the user, the rolling wheel 13 can be reset by the elastic member 17. When the circuit board 15 can be located below the optical code disk 16, the circuit board 15 may be provided with an avoidance hole for the optical code disk 16 to descend through.
[0059] Please refer to Figure 4 and Figure 5 , in an embodiment of the present invention, the support base 111 facing the bottom wall of the accommodation groove 131 is recessed to form a first groove 112 at the positions corresponding to the mounting cylinder 133 and the first boss 163. One end of the connecting shaft 117 close to the formation of the first groove 112 is connected to the bottom wall of the first groove 112. The mounting cylinder 133 and the first boss 163 are accommodated in the first groove 112. The first boss 163 abuts against the top wall of the first groove 112, and there is a gap between the first boss 163 and the bottom wall of the first groove 112.
[0060] It can be understood that by the top wall of the first groove 112 abutting against the first boss 163, the first groove 112 has a certain limiting effect on the first boss 163. At the same time, it also has a guiding effect on the optical code disk 16 and the rolling wheel 13 during the process of the rolling wheel 13 being driven to rotate by the user, that is, it rotates along the top wall of the first groove 112, which is beneficial to improving the stability of the rolling wheel 13 and the optical code disk 16 during the rotation process. There is a gap between the first boss 163 and the bottom wall of the first groove 112 for providing a clearance space when the rolling wheel 13 is pressed and driven by the user to descend. In addition, for the convenience of connecting the connecting shaft 117 and the bottom wall of the first groove 112, the bottom wall of the first groove 112 may be provided with a first clamping hole 113, and one end of the connecting shaft 117 close to the first groove 112 may be provided with a first clamping block 118, so that when the connecting shaft 117 is inserted into the first clamping hole 113, the connecting shaft 117 and the support base 111 can be quickly connected directly by the engagement of the first clamping block 118 and the first clamping hole 113. Or, in other embodiments, the connecting shaft 117 and the bottom of the second groove 114 can be connected by magnetic attraction or screw connection.
[0061] Please refer to Figure 3 and Figure 5 In an embodiment of the present invention, a limiting cylinder 137 is provided on the side wall surface of the rolling wheel 13 facing away from the notch of the accommodating groove 131. The limiting cylinder 137 extends in a direction away from the notch of the accommodating groove 131 and is sleeved outside the connecting shaft 117. A gap is formed between the top wall of the limiting cylinder 137 and the connecting shaft 117. The support base 111 facing away from the bottom wall of the accommodating groove 131 is provided with a second groove 114 at a position corresponding to the limiting cylinder 137. One end of the connecting shaft 117 close to the position where the second groove 114 is formed is connected to the bottom wall of the second groove 114. The limiting cylinder 137 is accommodated in the second groove 114 and abuts against the top wall of the second groove 114, and there is a gap between the limiting cylinder 137 and the bottom wall of the second groove 114.
[0062] It can be understood that by the top wall of the ear groove abutting against the limiting cylinder 137, the second groove 114 has a certain limiting effect on the limiting cylinder 137. At the same time, it also has a guiding effect on the rolling wheel 13 during the process of the rolling wheel 13 being driven to rotate by the user, that is, it rotates along the top wall of the second groove 114, which is beneficial to further improving the stability of the rolling wheel 13 during rotation. There is a gap between the top wall of the limiting cylinder 137 and the connecting shaft 117, and between the limiting cylinder 137 and the bottom wall of the second groove 114, which is used to provide a clearance space when the rolling wheel 13 is pressed and driven by the user to descend. In addition, the connecting shaft 117 and the bottom wall of the second groove 114 can also be an integral structure, so that the two can be formed integrally during processing without subsequent assembly of the two, which is beneficial to improving the convenience of assembling the mounting seat 111. At the same time, such a setting can also enhance the connection stability between the connecting shaft 117 and the bottom wall of the second groove 114. Of course, the present application is not limited to this. It is also possible that the bottom wall of the second groove 114 is provided with a second clamping hole, and one end of the connecting shaft 117 close to the second groove 114 can be provided with a second clamping block, so that when the connecting shaft 117 is inserted into the second connecting hole, the connecting shaft 117 and the support seat 111 can be quickly connected directly by the second clamping block and the second clamping hole. Or, the connecting shaft 117 and the bottom of the second groove 114 can be connected by magnetic attraction or screw connection.
[0063] Please refer to Figure 4 and Figure 7 , in an embodiment of the present invention, the support seat 111 facing the bottom wall of the accommodating groove 131 is provided with a guiding block 116 on the side wall surface in the accommodating cavity. When the rolling wheel 13 descends relative to the two support seats 111, the elastic arms 171 of the elastic member 17 are guided and driven by the guiding block 116, and collide with the support seat 111 facing the bottom wall of the accommodating groove 131 during elastic reset.
[0064] It can be understood that when the optical code disk 16 is driven by the rolling wheel 13 to descend, the elastic arm 171 of the elastic member 17 can be driven by the guiding block 116. Then, when the elastic arm 171 of the elastic member 17 is elastically reset, it can collide with the support seat 111 facing the bottom wall of the accommodating groove 131 to generate a prompting sound, so as to play a prompting role for the user to perform a pressing and confirmation operation. In this way, the possibility of omission or repeated pressing of the pressing operation on the rolling wheel 13 can be reduced, thereby improving the convenience of using the mouse 100. Among them, a first guiding surface can be formed at the upper end of the guiding block 116 to guide the elastic arm 171 of the elastic member 17 to rotate when the rolling wheel 13 descends relative to the mounting seat 111. Further, a second guiding surface can be formed at the lower end of the guiding block 116, so that during the process of the elastic arm 171 of the elastic member 17 resetting and rising, it can rotate under the guidance of the second guiding surface to bypass the guiding block 116 and return to the initial position. The first guiding surface and the second guiding surface can both be inclined surfaces, and the first guiding surface is inclined downward, and the second guiding surface is inclined upward.
[0065] Please refer to Figure 3 and Figure 5 , in an embodiment of the present invention, a second boss 167 is provided on the surface of the optical code disk 16 facing away from the bottom wall of the accommodating groove 131. The second boss 167 is annular and is arranged around the mounting cylinder 133; a positioning column 135 protrudes from the outer circumferential surface of one end of the mounting cylinder 133 close to the bottom wall of the accommodating groove 131, and the positioning column 135 passes through the second boss 167.
[0066] It can be understood that passing the positioning column 135 through the second boss 167 can play a limiting role on the optical code disk 16, reducing the possibility of the optical code disk 16 rotating on its own during the rotation of the rolling wheel 13, thereby being beneficial to ensuring that the optical code disk 16 can rotate synchronously with the rotation of the rolling wheel 13 normally and stably. Among them, a plurality of positioning columns 135 can be provided, and the plurality of positioning columns 135 are arranged around the circumference of the second boss 167. Of course, in other embodiments, the second boss 167 and the connecting shaft 117 can also be stably connected by glue bonding.
[0067] Please refer to Figure 2 , Figure 3 and Figure 5 , in an embodiment of the present invention, a mounting groove 139 is recessed on the outer circumferential surface of the rolling wheel 13. The mounting groove 139 is arranged around the circumference of the rolling wheel 13. The mouse scroll wheel 10 further includes an elastic ring 177, and the elastic ring 177 is embedded in the mounting groove 139.
[0068] It can be understood that the elastic ring 177 can be held by the user's finger. Since the elastic ring 177 has a certain elasticity, it can reduce the possibility of damage caused when the user holds and drives it, thus contributing to improving the safety of use. And the elastic ring 177 is embedded in the installation groove 139, which enables the elastic ring 177 to be directly limited by the installation groove 139 without the need to additionally set other structures to limit and fix the elastic ring 177, thereby simplifying the connection structure between the elastic ring 177 and the scroll wheel 13. Moreover, with such a setting, the elastic ring 177 can also be more compactly distributed on the scroll wheel 13, which is conducive to further reducing the overall volume of the mouse scroll wheel 10 by reducing its space occupation. Further, anti-slip protrusions can be provided on the outer circumferential surface of the elastic ring 177.
[0069] Please refer to Figure 2 and Figure 6 , in an embodiment of the present invention, the circuit board 15 is further provided with a lead 157.
[0070] It can be understood that through the lead 157, it is convenient to weld the power supply and signal lines for connection to the circuit board 15 of the mouse 100. Among them, multiple leads 157 can be provided, and the mounting seat 111 can be provided with openings at positions corresponding to the leads 157 so that the leads 157 are exposed to the outside. Further, a lighting source 159 can also be provided on the circuit board 15, and the light-emitting direction of the lighting source 159 is set upward so as to illuminate the scroll wheel 13 through the lighting source 159, facilitating the user to use the mouse 100 in an environment with relatively dim light.
[0071] Please refer to Figure 1 , the present invention also proposes a mouse 100, which includes a mouse scroll wheel 10. The specific structure of the mouse scroll wheel 10 refers to the above embodiments. Since this mouse 100 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the mouse scroll wheel 10 is clamped in the mouse housing 30 of the mouse 100 through the mounting seat 111 and is partially exposed to the outside.
[0072] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
