Description

Adjustable trackball mouse Technical Field

[0001] This invention relates to the field of mouse technology, and more particularly to a mouse. Background Technology

[0002] A mouse is an external input device for computers, serving as an indicator for positioning on the computer's display system using horizontal and vertical coordinates. It gets its name from its resemblance to a mouse. A trackball mouse is a type of mouse whose biggest advantage is that it doesn't require moving the mouse across the support surface like a mechanical mouse, thus saving space and reducing wrist fatigue for the user.

[0003] In some trackball mice currently on the market, the support for mounting the trackball can move relative to the mouse cover in the forward and backward direction (i.e., away from or closer to the user's body) to adjust the position of the trackball on the mouse cover, thereby meeting different user needs. However, trackballs that can only be adjusted in the forward and backward direction still have limited adjustment options. Summary of the Invention

[0004] To address at least one problem existing in the prior art, according to one aspect of the present invention, a mouse is provided, comprising:

[0005] Mouse body;

[0006] The adjustment mechanism includes a mounting base, a ball, and a bracket. The mounting base is installed inside the mouse body. The ball is rotatably disposed relative to the mounting base and can remain stationary relative to the mounting base. The bracket is connected to the ball and has a first receiving groove.

[0007] The trackball is mounted in the first receiving slot and is exposed relative to the mouse body.

[0008] In some embodiments, a portion of the bracket protrudes from the mouse body;

[0009] The adjustment mechanism further includes a first sliding member and a second sliding member that are slidably disposed opposite each other. The first sliding member is connected to the bracket, and the second sliding member is connected to the ball. The first sliding member can slide relative to the second sliding member and then remain stationary.

[0010] In some embodiments, the first slider is a columnar body, the second slider is a cylindrical body, and the second slider is slidably sleeved outside the first slider.

[0011] In some embodiments, the adjusting mechanism further includes an elastic sleeve, which is sleeved outside the first sliding member and slidably disposed with respect to the inner wall of the second sliding member.

[0012] In some embodiments, the first sliding member is provided with a slot, and the elastic sleeve is engaged in the slot.

[0013] In some embodiments, the first sliding member is provided with a limiting post, and the side wall of the second sliding member is provided with a limiting groove extending along the length direction of the second sliding member, and the limiting post is slidably disposed in the limiting groove.

[0014] In some embodiments, the mounting base includes a connector, a plastic base, and at least two limiting plates. The connector is connected to the mouse body, the plastic base is disposed within the connector and has a second receiving groove for receiving part of the ball, and each of the limiting plates is disposed on the side of the ball and connected to the connector to confine the ball within the second receiving groove.

[0015] In some embodiments, the bracket is provided with a light-transmitting hole, which is connected to the first receiving groove;

[0016] The mouse also includes an optical lens, an optical module, and a mounting bracket. The optical lens, the optical module, and the mounting bracket are installed inside the bracket, and the optical lens and the optical module are arranged corresponding to the light-transmitting hole. The optical lens and the mounting bracket are both connected to the optical module, and the mounting bracket is connected to the bracket.

[0017] In some embodiments, the bracket includes a detachably connected upper cover and a lower cover, the upper cover being provided with the first receiving groove, and the bracket being connected to the upper cover and / or the lower cover.

[0019] In summary, the mouse provided by this invention has the following technical effects:

[0020] The adjustment mechanism includes a mounting base inside the mouse body, and a ball that can rotate relative to the mounting base and remain stationary relative to it. The ball is connected to a support, which has a first receiving groove for the trackball to rotate. When the position of the trackball on the mouse body needs to be adjusted, the trackball is pushed, causing the ball connected to the support to rotate relative to the mounting base, thus adjusting the position of the trackball. Since the ball can rotate in all directions, the trackball can also be adjusted at various angles to meet the needs of different users. Attached Figure Description

Detailed Implementation

[0036] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] Please refer to Figures 1 to 14, which show a mouse 100 provided in an embodiment of the present invention, including a mouse body 10, an adjustment mechanism 20, and a trackball 30.

[0041] Referring to Figures 1 to 4, the mouse body 10 is placed on a support surface for operation by the user's hand; the adjustment mechanism 20 includes a mounting base 21, a ball 22, and a bracket 23. The mounting base 21 is installed inside the mouse body 10, the ball 22 is rotatably disposed relative to the mounting base 21 and can remain stationary relative to the mounting base 21, the bracket 23 is connected to the ball 22, and the bracket 23 is provided with a first receiving groove 231; the trackball 30 is rotatably disposed in the first receiving groove 231 and is exposed relative to the outer cover of the mouse 100.

[0042] The aforementioned mouse 100 has a mounting base 21 in the adjustment mechanism 20 installed inside the mouse body 10. It also includes a ball 22 that can rotate relative to the mounting base 21 and remain stationary relative to it. The ball 22 is connected to a support 23, which has a first receiving groove 231 for the trackball 30 to rotate. When the position of the trackball 30 on the mouse body 10 needs to be adjusted, pushing the trackball 30 causes the ball 22 connected to the support 23 to rotate relative to the mounting base 21, thus adjusting the position of the trackball 30. Since the ball 32 can rotate in all directions, the trackball 30 can also be adjusted at various angles to meet the needs of different users.

[0043] Understandably, since the trackball 30 needs to be adjusted in various directions relative to the mouse body 10, such as up, down, forward, or backward, the mouse body 10 is provided with an opening 11 for the trackball 30 to be exposed. 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 on the left side of the mouse body 10 for use by flicking with 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 closer to the user's body, "upward" refers to the direction away from the support surface that supports the mouse 100, and "downward" refers to the direction closer to the support surface that supports the mouse 100.

[0045] In some embodiments, the mouse body 10 also includes a main control PCB board, and the mouse body 10 may also have left and right buttons, a scroll wheel, and multiple function keys for user convenience. Referring to Figures 4 and 5, to ensure stable rolling of the trackball 30 within the first receiving groove 231, multiple rolling ball pillars 40 may be provided on the side wall of the first receiving groove 231. These rolling ball pillars 40 provide support for the trackball 30, allowing it to roll freely in various directions within the first receiving groove 231. In other embodiments, other spherical structures, such as spherical adjustment beads, may be provided on the support 23. The trackball 30 and the adjustment beads abut against each other to reduce resistance during rotation of the trackball 30.

[0046] Please refer to Figures 3, 4, and 6 to 14. In one embodiment of the present invention, to further increase the adjustment methods of the trackball 30, a portion of the support 23 protrudes from the mouse body 10. The adjustment mechanism 20 also includes a first slider 24 and a second slider 25 that are slidably disposed. The first slider 24 is connected to the support 23, and the second slider 25 is connected to the ball 22. The first slider 24 can slide relative to the second slider 25 and then remain stationary. Thus, by setting the first slider 24 and the second slider 25, and with the first slider 24 connected to the support 23, pulling the support 23 can achieve the sliding of the first slider 24 and the second slider 25, allowing the support 23 to protrude further away from the mouse body 10; or by pushing the support 23 towards the mouse body 10, causing the first slider 24 to slide relative to the second slider 25, the support 23 can slide into the mouse body 10, allowing the trackball 30 to retract into the mouse body 10, thereby increasing the adjustment range of the trackball 30. Thus, by sliding the first slider 24 and the second slider 25 against each other, the adjustment method of the trackball 30 is increased, meeting the usage needs of different customers.

[0047] Specifically, in this embodiment, the first sliding member 24 is a cylindrical body, and the second sliding member 25 is a cylindrical body. The second sliding member 25 is slidably sleeved outside the first sliding member 24. That is, under the drive of the bracket 23, the first sliding member 24 slides relative to the inner wall of the second sliding member 25. In this way, the cylindrical second sliding member 25 can be manufactured as a standard part with the ball 22, that is, manufactured and assembled as a ball shaft, improving the installation efficiency of the mouse 100. In other embodiments, the first sliding member 24 can also be set as a cylindrical body, and the second sliding member 25 can be set as a cylindrical body, as needed.

[0048] As can be understood, referring to Figure 3, since the first slider 24 and the second slider 25 will slide relative to each other, and the second slider 25 is connected to the ball 22, when the second slider 25 is basically fitted outside the first slider 24, the bracket 23 has a relief groove 232 on the side facing the ball 22 to avoid the ball 22. The relief groove 232 is formed by the bracket 23 being recessed in the direction away from the ball 22. The relief groove 232 is provided to avoid part of the ball 22, thereby increasing the sliding range between the first slider 24 and the second slider 25.

[0049] Further, please refer to Figures 4, 8 to 14. Since the first slider 24 and the second slider 25 will slide against each other and can achieve stillness after sliding, the adjustment mechanism 20 also includes an elastic sleeve 26. The elastic sleeve 26 is sleeved on the outside of the first slider 24 and slides against the inner wall of the second slider 25. At the same time, it abuts against the inner wall of the second slider 25. Thus, by setting the elastic sleeve 26, the friction force when sliding against the inner wall of the second slider 25 can be increased, and the hand feel when sliding can be increased. The sliding adjustment between the first slider 24 and the second slider 25 can be 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 ball 22. Thus, when the first sliding member 24 is pulled relative to the second sliding member 25 during the sliding process, the elastic sleeve 26 can always be located inside the second sliding member 25. In addition, it also avoids the risk that when the first sliding member 24 is pulled relative to the second sliding member 25 during the sliding process, the elastic sleeve 26 will detach from the second sliding member 25 and will be difficult to slide into the second sliding member 25.

[0051] In order to ensure the stability of the elastic sleeve 26 installed on the first sliding member 24, the first sliding member 24 is provided with a groove 241, and the elastic sleeve 26 is locked in the groove 241. Thus, the groove 241 is provided to position the installation position of the elastic sleeve 26, and at the same time, it also prevents the elastic sleeve 26 from falling off relative to the first sliding member 24 during the sliding process of the first sliding member 24 and the second sliding member 25.

[0052] Understandably, in some embodiments of the present invention, since the elastic sleeve 26 needs to have a certain degree of elasticity to achieve 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 or rubber. Any change in the material of the elastic sleeve 26 should be included within the scope of protection of the present invention.

[0053] Further, please refer to Figures 3, 4, and 7 to 14. In order to limit the sliding distance between the first sliding member 24 and the second sliding member 25 and prevent them from separating, the first sliding member 24 is provided with a limiting post 242, and the side wall of the second sliding member 25 is provided with a limiting groove 251 extending along the length direction of the second sliding member 25. The limiting post 242 is slidably disposed in the limiting groove 251, so that when the limiting post 242 is at both 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, as shown in Figures 11 to 14; and the contracted state of the first sliding member 24 in the second sliding member 25 is shown in Figures 7 to 10.

[0054] Referring to Figure 5, in this embodiment, when the mouse 100 is in use, a light-transmitting hole 236 is provided on the wall of the first accommodating groove 231, that is, the light-transmitting hole 236 and the first accommodating groove 231 are connected. The mouse 100 also includes an optical lens 60 and an optical module 50, which are set 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 disposed on the PCB board. When the trackball 30 rolls, the photoelectric sensor receives light signals 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 mounting bracket 70 are installed in the bracket 23. The optical lens 60 and the mounting bracket 70 are both connected to the optical module 50, and the mounting bracket 70 is connected to the bracket 23. In this way, by installing the optical lens 60 on the optical module 50, and at the same time connecting the optical module 50 to the mounting bracket 70, and then connecting the mounting bracket 70 to the bracket 23, the installation of the optical lens 60 and the optical module 50 can be achieved.

[0056] When the mounting bracket 70 is installed with the optical module 50, the mounting bracket 70 and the PCB board of the optical module 50 are riveted together and fixed. The PCB board has a slot in which the optical lens 60 is fixed.

[0057] Referring to Figure 4, the mouse 100 also includes a main control PCB. The optical module 50 in this embodiment is also provided with an FPC socket 51. The optical module 50 also includes an FPC cable 52. One end of the FPC cable 52 is inserted into the FPC socket 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] Referring to Figures 2 to 4 and Figures 6 to 14, to facilitate the installation of the optical module 50 and the optical lens 60 within the bracket 23, the bracket 23 includes a detachably connected upper cover 233 and a lower cover 234. The upper cover 233 has a first receiving groove 231 and a rolling ball column 40 for mounting, while the lower cover 234 has a clearance groove 232. The mounting bracket 70 is connected to the upper cover 233 and / or the lower cover 234. Thus, by configuring the bracket 23 to include the detachably connected upper cover 233 and lower cover 234, it is convenient to install the mounting bracket 70, the optical lens 60, and the optical module 50 within the bracket 23, and then connect the upper cover 233 and the lower cover 234. At the same time, since the optical lens 60 and the optical module 50 are sealed within the bracket 23, the bracket 23 can achieve dustproof and waterproof effects.

[0059] In this embodiment, the first sliding member 24 is mounted on the fixed upper cover 233.

[0060] In this embodiment, the fixing bracket 70 can be connected to the upper fixing cover 233, the lower fixing cover 234, or both. For example, when connected to the upper fixing cover 233, a plug-in post can be provided on the wall of the upper fixing cover 233 facing the lower fixing cover 234 for plug-in connection with the fixing bracket 70; the same arrangement can be used when connected to the lower fixing cover 234; or it can be plug-in connected to both the upper fixing cover 233 and the lower fixing cover 234.

[0061] Specifically, please refer to Figure 6. To facilitate the installation of the fixing bracket 70, the fixing upper cover 233, and the fixing lower cover 234, the fixing upper cover 233 is provided with a first insertion post 2331, the fixing lower cover 234 is provided with a second insertion post 2341, and the fixing bracket 70 is provided with a sleeve 71. Each end of the sleeve 71 is inserted and connected to the first insertion post 2331 and the second insertion post 2341, respectively. Thus, when installing the fixing bracket 70, the sleeve 71 can be fitted onto the first insertion post 2331. Then, when installing the fixing lower cover 234 and the fixing upper cover 233, the second insertion post 2341 of the fixing lower cover 234 is inserted into the other end of the sleeve 71, thereby realizing the docking connection of the three.

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

[0063] Understandably, there are other connecting posts and connecting cylinders between the fixed upper cover 233 and the fixed lower cover 234. The connecting posts and connecting cylinders are connected by insertion 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] Please refer to Figures 2, 4, and 7 to 14. To facilitate cleaning of the trackball 30, the bracket 23 also includes a guide cylinder 235. The guide cylinder 235 passes through the fixed lower cover 234 and the fixed upper cover 233. The fixed upper cover 233 has a first through hole 2332 corresponding to the channel of the guide cylinder 235, and the fixed lower cover 234 has a second through hole 2342 communicating with the channel of the guide cylinder 235, so that the channel of the guide cylinder 235 is connected to the first receiving groove 231, thereby facilitating the insertion of a rod into the channel of the guide cylinder 235 to push the trackball 30 out of the fixed upper cover 233.

[0065] Please refer to Figures 4, 6, and 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 within the connecting body 211 and has a second receiving groove 2121 for accommodating a portion of the ball 22. Each limiting plate 213 is disposed on the side of the ball 22 and is connected to the connecting body 211 to restrict the ball 22. The ball 22 is placed in the second receiving groove 2121 and exposed relative to the limiting plate 213. Thus, after setting the plastic base 212 in the connecting body 211, the ball 22 is installed in the plastic base 212. Then, the limiting plate 213 is installed on the connecting body 211 to restrict 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 in different positions.

[0066] Specifically, this embodiment includes two limiting plates 213. Each limiting plate 213 includes a semi-circular notch facing 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] The limiting plate 213 and the connecting body 211 are connected by bolts. In order to facilitate the limitation of the installation position of the limiting plate 213, a guide post 2111 can be provided on the connecting body 211, and a guide hole 2131 is provided on the limiting plate 213. When the limiting plate 213 is installed, the guide post 2111 passes through the guide hole 2131 on the limiting plate 213, thereby limiting the installation of the limiting plate 213 and avoiding interference to the rotation of the ball 22 due to inaccurate installation position of the limiting plate 213.

[0068] The mouse 100 is used as follows: when only the position of the trackball 30 needs to be adjusted, push the trackball 30 forward, backward, up, down, or to other positions; or at the same time, pull the bracket 23 to the outside of the mouse body 10 to pull the trackball 30 out a distance relative to the mouse body 10; or at the same time, push the trackball 30 to the center of the mouse body 10 a distance to accommodate the user's thumb in a comfortable position.

[0069] For the different adjusted states of the trackball 30 in this embodiment, please refer to Figures 7 to 13. Figures 7 to 10 are schematic diagrams of the first slider 24 and the second slider 25 in the retracted state; Figures 11 to 14 are schematic diagrams of the first slider 24 and the second slider 25 in the extended state.
