Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of 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 of 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] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0025] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0026] In this embodiment, "front", "rear", "left", "right", "upper", "lower" are relative positional relationships when the user holds the mouse for use.

[0027] Such as Figure 1 , Figure 2And Figure 3 As shown, this embodiment provides a mouse with an adjustable position of the optoelectronic IC, including an upper cover 1, a bottom cover 7, and a main board 2, an optoelectronic module, and a movement adjustment mechanism disposed between the upper cover 1 and the bottom cover 7; the optoelectronic module includes an optoelectronic IC 3, an optoelectronic PCB board 4, and a lens 5. The optoelectronic IC 3 is placed on the optoelectronic PCB board 4. The optoelectronic IC 3 is functionally connected to the optoelectronic PCB board 4 by welding, and thus is fixedly installed with the optoelectronic PCB board 4. A first opening 12 for the light source of the optoelectronic IC 3 to pass through is provided on the optoelectronic PCB board 4. The positioning part at the center of the lens 5 passes through the first opening 12 and is connected to the optoelectronic IC 3. The optoelectronic PCB board 4 is electrically connected to the main board 2. The optoelectronic module is fixedly installed on the movement adjustment mechanism. A second opening 11 corresponding to the photosensitive position of the optoelectronic IC 3 is provided on the movement adjustment mechanism. The movement adjustment mechanism is movably installed on the bottom cover 7 and can move in the front-back direction of the bottom cover 7. A third opening 9 corresponding to the second opening 11 is provided on the bottom cover 7. Among them, the positioning part at the center of the lens 5 passes through the first opening 12 of the optoelectronic PCB board 4 and is combined and fixed with the optoelectronic IC 3. The connection mode between the lens 5 and the optoelectronic IC 3 can be movable or fixed, which is selected according to different design methods of different optoelectronic ICs 3.

[0028] Since the optoelectronic IC (sensor) 3 of the mouse is the component that controls the cursor movement, and generally users operate the mouse in a circular or arc motion with the wrist or arm as the pivot point. For the same movement range, the closer the photosensitive position of the optoelectronic IC 3 of the mouse is to the front relative to the mouse itself, the closer the sensor is to the periphery of the active circle or arc, and the greater the displacement detected by the sensor. Conversely, the closer it is to the rear, the smaller the detected displacement. Therefore, by adjusting the relative position of the sensor on the mouse, the distance and accuracy of the cursor movement within the same movement range of the mouse can be changed. Also, because each user holds the mouse in a different position, some users hold the mouse closer to the front and some hold it closer to the rear, which also affects the movement distance and accuracy of the cursor. In this embodiment, the optoelectronic IC 3, the optoelectronic PCB board 4, and the lens 5 are modularized to form an optoelectronic module, which is integrally assembled onto the moving adjustment mechanism. By the relative movement of the moving adjustment mechanism on the bottom cover 7, the entire optoelectronic module can be moved forward and backward relative to the bottom cover 7, thereby realizing the adjustable position of the optoelectronic IC 3. In this way, users can better control the movement and positioning accuracy of the mouse cursor according to their own usage habits and operation methods, thus meeting the needs of different users. At the same time, through the settings of the first opening 12 on the PCB board 4, the second opening 11 on the moving adjustment mechanism, and the third opening 9 on the bottom cover 7, it is effectively ensured that the light source of the optoelectronic IC 3 can pass through the bottom cover 7 and be reflected onto the working surface where the mouse is used. Since the positions of the optoelectronic IC 3, the PCB board 4, and the moving adjustment mechanism are relatively fixed, the sizes of the first opening 12 and the second opening 11 only need to ensure that the light source of the optoelectronic IC 3 can pass through. Since the optoelectronic IC 3 is adjusted by the moving adjustment mechanism, the front and rear positions of the optoelectronic IC 3 relative to the bottom cover 7 will change. Therefore, the length of the third opening 9 on the bottom cover 7 needs to be not less than the maximum adjustment distance of the optoelectronic module, so as to always ensure that the light source of the optoelectronic IC 3 can still pass through the bottom cover 7 and be reflected onto the working surface where the mouse is used after the position adjustment of the optoelectronic IC 3.

[0029] In a refined implementation manner, the main control chip of the entire mouse is arranged on the main board 2. At the same time, a fourth opening 18 is opened in the middle of the main board 2 to make way for the forward and backward movement adjustment of the optoelectronic module. At the same time, a first socket 14 is provided on the upper surface of the optoelectronic PCB board 4, and a second socket 17 is correspondingly provided on the main board 2. The first socket 14 and the second socket 17 connect and communicate the entire control signals of the optoelectronic IC 3 and the main board 2 through a connecting wire 16.

[0030] For a specific implementation manner of the forward and backward position movement adjustment of the optoelectronic module relative to the bottom cover 7, such as Figure 2 、 Figure 3 and Figure 4As shown, the moving adjustment mechanism includes a moving base 6 and a sliding shaft 10. The optoelectronic PCB board 4 is fixedly installed on the moving base 6. The second opening 11 is provided at the center of the moving base 6. Through holes 21 are symmetrically provided on both sides of the second opening 11 on the moving base 6. The sliding shaft 10 passes through the through holes 21. A limiting member for limiting the installation of the sliding shaft 10 is provided on the bottom cover 7. By means of the limiting member, the position of the sliding shaft 10 relative to the bottom cover 7 is fixed. In this way, the moving base 6 can slide on the sliding shaft 10 through the through holes 21, so as to realize the front-back position sliding adjustment of the optoelectronic module relative to the bottom cover 7. The adjustment method is simple, and the structural design of the moving adjustment mechanism will not affect the light source transmission of the optoelectronic IC 3.

[0031] For the structural form of limiting the sliding shaft 10, it is only necessary to ensure that there is no relative displacement of the sliding shaft 10 relative to the bottom cover 7. Preferably, as Figure 5 shown, the limiting member includes a limiting block 25 and a limiting groove 26. For the structural form with two symmetrically arranged sliding shafts 10 in this embodiment, specifically, four limiting blocks 25 and four limiting grooves 26 are provided. One limiting block 25 is symmetrically provided at each end of each sliding shaft 10. The limiting groove 26 is located between the limiting block 25 and the through hole 21 of the moving base 6. The end of the sliding shaft 10 passes through the limiting groove 26 and abuts against the limiting block 25. The front-back position of the sliding shaft 10 is restricted by the limiting block 25, and the left-right and up-down positions of the sliding shaft 10 are restricted by the limiting groove 25, so as to limit the optoelectronic module to the bottom cover 7 and can slide along the sliding shaft 10, realizing the adjustable front-back position of the optoelectronic module relative to the bottom cover 7.

[0032] As a specific fixed connection method between the optoelectronic module and the moving adjustment mechanism, as Figure 1 and Figure 4 shown, two diagonal positioning posts 20 and two diagonal fixed screw posts 19 are respectively provided at the four corners of the moving base 6. At the same time, positioning holes 15 and screw holes 13 are provided on the optoelectronic PCB board 4 corresponding to the positions of the positioning posts 20 and the fixed screw posts 19 of the moving base 6. The optoelectronic PCB board 4 and the moving base 6 are assembled through the cooperation of the positioning holes 15 and the positioning posts 20, and the screw holes 13 and the fixed screw posts 19, and then the assembled optoelectronic PCB board 4 and the moving base 6 are fixed by screws.

[0033] In an optimized implementation manner, the above-mentioned mouse with adjustable optoelectronic IC position further includes a locking component for fixing the position of the moving adjustment mechanism after adjustment. When the entire optoelectronic module is adjusted to a suitable position, the relative position of the moving adjustment mechanism and the bottom cover 7 can be locked through the locking component, so as to avoid the movement of the optoelectronic module during the use of the mouse and ensure the accuracy of the movement and positioning of the mouse cursor. Specifically, asFigure 1 , Figure 4 and Figure 5 As shown, the locking assembly includes a fixing screw 8, and screw fixing openings 24 that match the fixing screw 8 are symmetrically provided on both sides of the bottom cover 7, and the length of the screw fixing opening 24 is not less than the maximum adjustment distance of the photoelectric module, and the width of the screw fixing opening 24 is less than the nut diameter of the fixing screw 8. The movable adjustment mechanism is provided with a fixing screw hole 22 that matches the fixing screw 8. Specifically, the fixing screw hole 22 is arranged on the outside of the through hole 21 on the mobile base 6. When the photoelectric module is adjusted to a suitable position, the fixing screw 8 passes through the screw fixing opening 24 of the bottom cover 7 and is inserted into the fixing screw hole 22 of the mobile base 6, and the relative position of the mobile base 6 and the bottom cover 7 is locked by the fixing screw 8. Further, a copper nut 23 can be provided in the fixing screw hole 22 to prevent the fixing screw from slipping due to frequent adjustment and being unable to be locked.

[0034] In this embodiment, the movement of the movable base relative to the bottom cover can be achieved by loosening the fixing screw with a screwdriver and then inserting the screwdriver into the nut of the fixing screw to drive the movable base to slide back and forth. The fixing screw can also be loosened and then the second opening of the movable base can be moved by hand or a tool to slide back and forth. Of course, the movement method of the movable base is not limited to the methods listed here.

[0035] To sum up, the photoelectric IC position adjustable mouse provided by the present invention fixes the photoelectric module as a whole on the movable adjustment mechanism, and realizes the front and rear position movement adjustment of the entire photoelectric module relative to the bottom cover through the movable adjustment mechanism, so that the user can better control the movement and positioning accuracy of the mouse cursor according to his own usage habits and operating methods to meet the needs of different users.

[0036] The above examples are merely illustrative of the present invention and do not constitute a limitation on the protection scope of the present invention. All designs that are the same or similar to the present invention fall within the protection scope of the present invention.
