DETAILED DESCRIPTION

[0036] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] See also Figures 1 to 14 , a mouse 100 provided in an embodiment of the present invention includes a mouse body 10 , an adjustment mechanism 20 and a trackball 30 .

[0041] Among them, see Figures 1 to 4The mouse body 10 is used to be placed on a support surface for the operator to operate with his hand; the adjustment mechanism 20 includes a mounting seat 21, a ball 22 and a bracket 23, the mounting seat 21 is installed in the mouse body 10, the ball 22 is rotatably arranged relative to the mounting seat 21, and can be stationary relative to the mounting seat 21, the bracket 23 is connected to the ball 22, and a first accommodating groove 231 is provided on the bracket 23; the trackball 30 is rotatably arranged in the first accommodating groove 231, and is exposed relative to the outer cover of the mouse 100.

[0042] In the above-mentioned mouse 100, the mounting seat 21 in the adjustment mechanism 20 is installed in the mouse body 10, and is provided with a ball 22 that can rotate relative to the mounting seat 21 and can be stationary relative to the mounting seat 21. The ball 22 is connected to the bracket 23, and the bracket 23 is provided with a first accommodating groove 231 for the trackball 30 to rotate. Therefore, when it is necessary to adjust the placement position of the trackball 30 on the mouse body 10, the trackball 30 is pushed, and the trackball 30 drives the ball 22 connected to the bracket 23 to rotate relative to the mounting seat 21, so that the placement position of the trackball 30 can be adjusted. Since the ball 32 can rotate in various directions, the trackball 30 can also be adjusted at various angles to meet the usage requirements of different users.

[0043] It is understandable that since the trackball 30 needs to be adjusted in various directions relative to the mouse body 10, such as upward, downward, forward or backward, the mouse body 10 is provided with an opening 11 for exposing the trackball 30, and the opening area of ​​the opening 11 is larger than the maximum cross-sectional area of ​​the trackball 30, so that the trackball 30 can be adjusted in various directions. Furthermore, the trackball 30 is exposed from the left side of the mouse body 10 and is used by the thumb.

[0044] It should be noted that, in this embodiment, forward refers to the direction away from the user's body, backward refers to the direction close to the user's body, upward refers to the direction away from the supporting surface supporting the mouse 100, and downward refers to the direction close to the supporting surface supporting the mouse 100.

[0045] In some embodiments, a main control PCB is further provided in the mouse body 10, and the mouse body 10 may also be provided with buttons such as a left button, a right button, a scroll wheel button, and a plurality of function keys, so as to facilitate the use of the user. Figure 4 and Figure 5In order to allow the trackball 30 to roll stably in the first receiving groove 231, a plurality of rolling ball posts 40 may be provided on the side wall of the first receiving groove 231. The plurality of rolling ball posts 40 provide support for the trackball 30, so that the trackball 30 can roll freely in various directions in the first receiving groove 231. In other embodiments, other spherical structures, such as spherical adjustment beads, may be provided on the bracket 23. The trackball 30 and the adjustment beads are supported against each other to achieve the rotation of the trackball 30 with reduced resistance.

[0046] See also Figure 3 , Figure 4 as well as Figures 6 to 14 In one embodiment of the present invention, in order to further increase the adjustment mode of the trackball 30, part of the bracket 23 protrudes from the mouse body 10; the adjustment mechanism 20 also includes a first sliding member 24 and a second sliding member 25 that are slidably arranged, the first sliding member 24 is connected to the bracket 23, the second sliding member 25 is connected to the ball 22, and the first sliding member 24 can slide relative to the second sliding member 25 and then stop. In this way, by setting the first sliding member 24 and the second sliding member 25, and the first sliding member 24 is connected to the bracket 23, the bracket 23 can be pulled to achieve the sliding of the first sliding member 24 and the second sliding member 25, so that the bracket 23 is moved away from the mouse body 10 so that it can protrude more relative to the mouse body 10; or the bracket 23 is pushed toward the direction of the mouse body 10, so that the first sliding member 24 slides relative to the second sliding member 25, and the bracket 23 can be slid into the mouse body 10, so that the trackball 30 is partially retracted into the mouse body 10, thereby increasing the adjustment range of the trackball 30. In this way, according to the mutual sliding of the first sliding member 24 and the second sliding member 25 , the adjustment methods of the trackball 30 are increased, thereby meeting the usage requirements of different customers.

[0047] Specifically, the first sliding member 24 of the present embodiment is a columnar body, and the second sliding member 25 is a tubular body. The second sliding member 25 is slidably sleeved outside the first sliding member 24, that is, driven by the bracket 23, the first sliding member 24 slides relative to the inner wall of the second sliding member 25. In this way, the second sliding member 25 configured as a tubular body can be produced as a standard part with the ball 22, that is, produced and assembled as a ball shaft, thereby improving the installation efficiency of the mouse 100. In other embodiments, the first sliding member 24 can also be configured as a tubular body and the second sliding member 25 can be configured as a columnar body as needed.

[0048] Understandably, see Figure 3Since the first sliding member 24 and the second sliding member 25 slide against each other, the second sliding member 25 is connected to the sphere 22. When the second sliding member 25 is basically sleeved outside the first sliding member 24, the bracket 23 is provided with a relief groove 232 on the side facing the sphere 22 for evading the sphere 22. The relief groove 232 is formed by the bracket 23 being recessed in a direction away from the sphere 22. The relief groove 232 is provided to evade part of the sphere 22, thereby increasing the sliding range between the first sliding member 24 and the second sliding member 25.

[0049] For further information, see Figure 4 , Figures 8 to 14 Since the first sliding member 24 and the second sliding member 25 will slide against each other and can achieve stillness after sliding, the adjustment mechanism 20 also includes an elastic sleeve 26, which is sleeved on the outside of the first sliding member 24 and slidably arranged on the inner wall of the second sliding member 25, and at the same time abuts against the inner wall of the second sliding member 25. Therefore, through the setting of the elastic sleeve 26, the friction force when sliding with the inner wall of the second sliding member 25 can be increased, the feel of the hand when sliding is increased, and the sliding adjustment between the first sliding member 24 and the second sliding member 25 is achieved in a gradual sliding manner.

[0050] Furthermore, in order to ensure that the first sliding member 24 and the second sliding member 25 always generate sliding friction through the elastic sleeve 26 during the sliding process, the elastic sleeve 26 is sleeved on the end of the first sliding member 24 facing the sphere 22, so that when the first sliding member 24 is pulled relative to the second sliding member 25 to slide, the elastic sleeve 26 can always be located in the second sliding member 25. Furthermore, the risk of the elastic sleeve 26 detaching from the second sliding member 25 and having difficulty sliding into the second sliding member 25 when the first sliding member 24 is pulled relative to the second sliding member 25 to slide is avoided.

[0051] Among them, in order to ensure the stability of the elastic sleeve 26 installed on the first sliding member 24, a card slot 241 is provided on the first sliding member 24, and the elastic sleeve 26 is clamped in the card slot 241. Therefore, the setting of the card slot 241 locates the installation position of the elastic sleeve 26, and also avoids the elastic sleeve 26 from falling off relative to the first sliding member 24 when the first sliding member 24 and the second sliding member 25 are sliding with each other.

[0052] It is understandable that in some embodiments of the present invention, since the elastic sleeve 26 needs to have a certain elasticity so as to be able to have an interference fit with the inner wall of the second sliding member 25, the elastic sleeve 26 can be made of elastic materials such as silicone and rubber. Any material changes of the elastic sleeve 26 should be included in the protection scope of the present invention.

[0053] For further information, see Figure 3 , Figure 4 as well as Figures 7 to 14 In order to limit the sliding distance between the first sliding member 24 and the second sliding member 25 to prevent the two from being separated, a limiting column 242 is provided on the first sliding member 24, and a limiting groove 251 extending along the length direction of the second sliding member 25 is provided on the side wall of the second sliding member 25. The limiting column 242 is slidably arranged in the limiting groove 251, so that when the limiting column 242 is at the two ends of the limiting groove 251, it is the maximum stretching state of the first sliding member 24 relative to the second sliding member 25, for example Figures 11 to 14 and the first sliding member 24 in the second sliding member 25 within the contraction state such as Figures 7 to 10 shown.

[0054] Among them, see Figure 5 When the mouse 100 of this embodiment is in use, a light-transmitting hole 236 is provided on the groove wall of the first accommodating groove 231, that is, the light-transmitting hole 236 is connected to the first accommodating groove 231. The mouse 100 also includes an optical lens 60 and an optical module 50. The optical lens 60 and the optical module 50 are arranged corresponding to the light-transmitting hole 236. The optical lens 60 is used to refract and focus light. The optical module 50 includes a PCB board and a photoelectric sensor arranged on the PCB board. When the trackball 30 rolls, the photoelectric sensor receives the light signal to sense the movement trajectory of the trackball 30.

[0055] Specifically, when installing the optical lens 60 and the optical module 50, the optical lens 60, the optical module 50 and the fixing frame 70 are installed in the bracket 23, the optical lens 60 and the fixing frame 70 are both connected to the optical module 50, and the fixing frame 70 is connected to the bracket 23. In this way, by installing the optical lens 60 on the optical module 50, and the optical module 50 is connected to the fixing frame 70, and the fixing frame 70 is connected to the bracket 23, the installation of the optical lens 60 and the optical module 50 can be achieved.

[0056] When the fixing frame 70 is installed with the optical module 50 , the fixing frame 70 and the PCB board of the optical module 50 are riveted and fixed, and a slot is provided in the PCB board, and the optical lens 60 is clamped in the slot.

[0057] Among them, see Figure 4 The mouse 100 also includes a main control PCB. The optical module 50 of this embodiment is also provided with an FPC seat 51. The optical module 50 also includes an FPC cable 52. One end of the FPC cable 52 is plugged into the FPC seat 51, and the other end is used to connect to the main control PCB, thereby realizing signal transmission between the optical module 50 and the main control PCB.

[0058] Among them, see Figures 2 to 4 as well as Figures 6 to 14In order to facilitate the installation of the optical module 50 and the optical lens 60 in the bracket 23, the bracket 23 includes a detachably connected fixed upper cover 233 and a fixed lower cover 234, the fixed upper cover 233 is provided with a first accommodating groove 231, and the above-mentioned rolling ball column 40 is installed, the fixed lower cover 234 is provided with the above-mentioned avoidance groove 232, and the fixed frame 70 is connected to the fixed upper cover 233 and / or the fixed lower cover 234. In this way, the bracket 23 is configured to include a detachably connected fixed upper cover 233 and a fixed lower cover 234, which facilitates the installation of the fixed frame 70, the optical lens 60 and the optical module 50 in the bracket 23, and then the fixed upper cover 233 and the fixed lower cover 234 are connected; at the same time, since the optical lens 60 and the optical module 50 are sealed in the bracket 23, the bracket 23 can achieve a dustproof and waterproof effect.

[0059] The first sliding member 24 of this embodiment is installed on the fixed upper cover 233 .

[0060] The fixing frame 70 of this embodiment can be connected to the fixed upper cover 233, can be connected to the fixed lower cover 234, or can be connected to both the fixed upper cover 233 and the fixed lower cover 234. For example, when connected to the fixed upper cover 233, plug-in columns can be set on the wall surface of the fixed upper cover 233 facing the fixed lower cover 234 to be plug-in connected to the fixing frame 70; the same setting method can be adopted when connected to the fixed lower cover 234; or the fixing frame 70 can be plug-in connected to both the fixed upper cover 233 and the fixed lower cover 234.

[0061] Specifically, see Figure 6 In order to facilitate the installation among the fixing frame 70, the fixed upper cover 233 and the fixed lower cover 234, a first plug-in column 2331 is provided on the fixed upper cover 233, a second plug-in column 2341 is provided on the fixed lower cover 234, and a sleeve 71 is provided on the fixing frame 70. Each end of the sleeve 71 is respectively plugged and connected with the first plug-in column 2331 and the second plug-in column 2341. In this way, when installing the fixing frame 70, the sleeve 71 can be sleeved on the first plug-in column 2331. Later, when the fixed lower cover 234 and the fixed upper cover 233 are installed, the second plug-in column 2341 of the fixed lower cover 234 is plugged into the other end of the sleeve 71, thereby realizing the docking connection between the three.

[0062] Furthermore, in order to ensure the stability of the installation of the fixing frame 70, the three are also connected by bolts, and the bolts penetrate into the fixed lower cover 234 from the side of the fixed lower cover 234 away from the fixed upper cover 233, and pass through the second plug-in column 2341 and the sleeve 71, and extend into the first plug-in column 2331, thereby stably installing the fixing frame 70 on the entire bracket 23.

[0063] It can be understood that other docking posts and docking tubes are provided between the fixed upper cover 233 and the fixed lower cover 234 . The docking posts and the docking tubes are plugged in and connected and then fixed by bolts, thereby ensuring the stability of the connection between the fixed upper cover 233 and the fixed lower cover 234 .

[0064] Among them, see Figure 2 , Figure 4 as well as Figures 7 to 14 In order to facilitate cleaning of the trackball 30, the bracket 23 further includes a guide cylinder 235, which is penetrated by the fixed lower cover 234 and the fixed upper cover 234, and the fixed upper cover 233 is provided with a first penetration hole 2332 corresponding to the channel of the guide cylinder 235, and the fixed lower cover 234 is provided with a second penetration hole 2342 connected to the channel of the guide cylinder 235, so that the channel of the guide cylinder 235 is connected to the first accommodating groove 231, so that it is convenient to extend the rod into the channel of the guide cylinder 235 to eject the trackball 30 from the fixed upper cover 233.

[0065] See also Figure 4 , Figure 6 as well as Figures 7 to 14 In one embodiment of the present invention, the mounting base 21 includes a connecting body 211, a plastic base 212 and at least two limiting plates 213. The connecting body 211 is connected to the mouse body 10. The plastic base 212 is disposed in the connecting body 211 and is provided with a second receiving groove 2121. The second receiving groove 2121 is used to accommodate part of the ball 22. The limiting plates 213 are respectively disposed on the sides of the ball 22 and are respectively connected to the connecting body 211 to limit the ball 22 in the second receiving groove 21. 21, and the ball 22 is exposed relative to the limiting plate 213. In this way, after the plastic base 212 is set in the connecting body 211, the ball 22 is installed in the plastic base 212, and then the limiting plate 213 is installed on the connecting body 211 to limit the ball 22 in the plastic base 212. At the same time, the ball 22 and the plastic base 212 can rotate relative to each other and have friction to stop in any state after rotation, thereby realizing the adjustment of the trackball 30 at different positions.

[0066] Specifically, the present embodiment includes two limiting plates 213, each limiting plate 213 includes a semicircular notch, which is arranged toward the sphere 22. After the limiting plates 213 and the connector 211 are installed, the installation of the sphere 22 on the plastic base 212 can be restricted to prevent it from falling out.

[0067] Among them, the limit plate 213 and the connecting body 211 are connected by bolts. In order to facilitate the limitation of the installation position of the limit plate 213, a guide column 2111 can be provided on the connecting body 211, and a guide hole 2131 is provided on the limit plate 213. When the limit plate 213 is installed, the guide column 2111 passes through the guide hole 2131 on the limit plate 213, thereby limiting the installation of the limit plate 213 and avoiding interference with the rotation of the sphere 22 due to inaccurate installation position of the limit plate 213.

[0068] The method of using the above-mentioned mouse 100 is: when only the position of the trackball 30 needs to be adjusted, the trackball 30 is pushed to rotate forward, backward, upward, downward or to other positions; or the bracket 23 can be pulled toward the outside of the mouse body 10 at the same time to pull the trackball 30 out a certain distance relative to the mouse body 10; or the trackball 30 can be pushed toward the center of the mouse body 10 at the same time to adapt to the user's thumb in a comfortable using state.

[0069] The different adjusted states of the trackball 30 of this embodiment are shown in FIG. Figures 7 to 13 .in, Figures 7 to 10 is a schematic diagram of the first sliding member 24 and the second sliding member 25 in a retracted state; Figures 11 to 14 Schematic diagram of the first sliding member 24 and the second sliding member 25 in a stretched state.
