BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present disclosure relates to a mouse adjusting device; in particular, to a mouse adjusting device for adjusting the height of a sensing module of a mouse. 
     2. Description of Related Art 
     In today&#39;s world of ever advancing technology, personal computers, laptops, tablets, and portable devices of different dimensions have become irreplaceable tools in people&#39;s lives, and mouses are common input devices for the abovementioned equipment. However, typical mouses do not meet the demands of specific users, e.g. professional e-sport gamers. Therefore, adjustable mouses which allow users to adjust the sensitivity (e.g. for gaming, office work) are made in the market. Mouse sensitivity is especially important to professional e-sport gamers, because quick movements and micromanagement are required in games, e.g. turning around quickly, and aiming at the enemy causes the mouse to be raised slightly and then lowered. If the mouse sensitivity is too high, continued sensing when the gamer does not raise the mouse sufficiently high results in error. However, adjusting the mouse sensitivity during games requires jumping to an operating system window to adjust settings, which is impractical. 
     Hence, the present inventor believes the above mentioned disadvantages can be overcome, and through devoted research combined with application of theory, finally proposes the present disclosure which has a reasonable design and effectively improves upon the above mentioned disadvantages. 
     SUMMARY OF THE INVENTION 
     The object of the present disclosure is to provide a mouse adjusting device for raising and lowering a sensing module of a mouse, to accommodate needs of users. 
     In order to achieve the aforementioned objects, the present disclosure provides a mouse adjusting device for adjusting the height of a sensing module of a mouse. The mouse adjusting device includes: a slidable base slidably disposed at a lower portion of the mouse and formed with at least one ramp portion thereunder; a sensor carrier raisably and lowerably disposed at the lower portion of the mouse and under the slidable base, wherein the sensor carrier accommodates the sensing module, and a top portion of the sensor carrier is formed with at least one block portion abutting the ramp portion of the slidable base; and an adjusting element having a drive screw and a drive nut, wherein the drive nut is embedded in the slidable base, one end of the drive screw is rotatably exposed outside the mouse, and another end of the drive screw is rotatably engaged to the drive nut. 
     In summary of the above, the mouse adjusting device of the present disclosure through the sliding of the slidable base, the raising and lowering of the sensor carrier, engagement between the ramp portion formed at a bottom portion of the slidable base and a block portion formed at the top portion of the sensor carrier, rotatable connection of the drive screw of the adjusting element to the drive nut, and embedment of the drive nut on the slidable base, when the drive screw rotates relative to the drive nut, the drive nut, the slidable base and the block portion are driven to move horizontally, such that the ramp portion is forced to slide with respect to the block portion, thereby driving the sensor carrier and the sensing module to move vertically, such that rotation of the adjusting element enables the adjusting device to translate horizontal movement of the slidable base to a vertical movement of the sensor carrier, achieving the function of raising and lowering the sensing module to meet different needs of the user.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The aforementioned illustrations and following detailed descriptions are exemplary for the purpose of further explaining the scope of the present disclosure. Other objectives and advantages related to the present disclosure will be illustrated in the subsequent descriptions and appended drawings. 
     Referring to  FIG. 1  to  FIG. 4  showing a first embodiment of the present disclosure, the present disclosure provides a mouse adjusting device. As shown in  FIG. 1  and  FIG. 2 , a mouse  10  can be defined into an upper portion  11  and a lower portion  12 , and an adjusting device  20  is disposed at the lower portion  12  of the mouse  10 . The adjusting device  20  adjusts the height of a sensing module  13  of the mouse  10 . The sensing module  13 , e.g. an optical sensing module or a laser sensing module, detects direction and distance of motion of the mouse  10  for positioning the cursor. The present embodiment does not limit the type of the sensing module  13 . Additionally, it is worth noting that the mouse  10  includes other components, such as a roller, buttons, micro switches, etc. respectively disposed at the upper portion  11  or the lower portion  12  of the mouse  10 , and not further described herein. The adjusting device  20  of the present embodiment includes a slidable base  21 , a sensor carrier  22 , and an adjusting element  23 . 
     The slidable base  21  is slidably disposed at the lower portion  12  of the mouse  10 . The bottom portion  210  of the slidable base  21  has at least one ramp portion  211 . In the present embodiment, the bottom portion  210  of the slidable base  21  has two ramp portions  211  which are parallel. Preferably, the shape of the ramp portions  211  is a trapezoid, and the ramp portions  211  each have a slanted face  2111  (as shown in  FIG. 4 ). 
     The sensor carrier  22  is raisably and lowerably disposed at the lower portion  12  of the mouse  10  and under the slidable base  21 . The sensor carrier  22  accommodates the sensing module  13 , and a top portion  220  of the sensor carrier  22  is formed with at least one block portion  221  abutting the ramp portion  211 . In the present embodiment, the top portion  220  of the sensor carrier  22  has two block portions  221  which are parallel, such that the two block portions  221  can respectively abut the two ramp portions  211 . Preferably, the block portions  221  are curved protrusions and each have a curved face  2211  (as shown in  FIG. 4 ). 
     The adjusting element  23  has a drive screw  231  and a drive nut  232 . The drive nut  232  is embedded in the slidable base  21 . One end of the drive screw  231  is rotatably exposed outside the mouse  10 , and another end of the drive screw  231  is rotatably engaged to the drive nut  232 . Therefore, when the drive screw  231  of the adjusting element  23  rotates with respect to the drive nut  232 , the drive nut  232  and the slidable base  21  are driven to move horizontally along the direction of the axis of the drive screw  231 , thereby driving the ramp portions  211  to move horizontally with the slidable base  21 , in turn driving the block portions  221  abutting the ramp portions  211  to move vertically, thereby driving the sensor carrier  22  and the sensing module  13  accommodated thereon to move vertically. The following describe the slidable base  21 , sensor carrier  22 , and adjusting element  23 , and then the connection relationships and relative motions therebetween. 
     The slidable base  21  is a frame having multiple edges, in other words a structure formed by connected beams, or in other words the ramp portions  211  of the slidable  21  is formed by downward extensions of the bottom portion  210  of the beams. Additionally, the slidable base  21  is formed with a plurality of through holes  212 , and the lower portion  12  of the mouse  10  is formed with a plurality of columns  121 . The columns  121  respectively pass through the through holes  212 . Through the couplings of the through holes  212  and the columns  121 , the slidable base  21  stably moves horizontally about the lower portions  12  of the mouse  10 , and the distance of horizontal movement of the slidable base  21  is limited. Additionally, the through holes  212  can be formed with screws, such that the slidable base  21  can stably move horizontally without disengaging. Also, the slidable base  21  is formed with an embedding groove  213 , and the drive nut  232  is embedded in the embedding groove  213 . 
     The center of the sensor carrier  22  is recessed and formed with an accommodating portion  222 . The sensing module  13  is accommodated in the accommodating portion  222  such that the sensor carrier  22  carries the sensing module  13 . Additionally, the sensor carrier  22  has a plurality of elastic units  223 . One end of each of the elastic units  223  is vertically disposed at the sensor carrier  22 , and another end of each of the elastic units  223  abuts the lower portion  12  of the mouse  10 . Preferably the sensor carrier  22  has four elastic units  223 , respectively disposed at four corners of the sensor carrier  22 . Each of the four corners of the sensor carrier  22  is formed with an extension portion  224  extending outward and horizontally. One end of each of the elastic units  223  is vertically disposed at the respective extension portion  224  of the sensor carrier  22 . Another end of each of the elastic units  223  vertically abuts the lower portion  12  of the mouse  10 . Therefore, when the elastic units  223  are compressed, the sensor carrier  22  is lowered, and when the elastic units  223  are released, the sensor carrier  22  is raised, such that the sensor carrier  22  is raisably and lowerably disposed at the lower portion  12  of the mouse through the compression and release of the elastic units  223 . Moreover, through the arrangement of the elastic units  223 , the block portions  221  of the sensor carrier  22  can resiliently abut the ramp portions  211  of the slidable base  21  through the elastic force provided by the elastic units  223 , such that the ramp portions  211  and the block portions  221  are securely in contact. Additionally, edges of the sensor carrier  22  are formed with a plurality of vertical guiding portions  225 , and the lower portion  12  of the mouse  10  is formed with a plurality of recesses  122 . The guiding portions  225  can respectively slide into the recesses  122 . Through the couplings of the guiding portions  225  and the recesses  122 , the raising and lowering of the sensor carrier  22  is not tilted derailed. 
     One end of the drive screw  231  of the adjusting element  23  is formed with a wheel  2311  rotatably exposed outside an opening structure  123  of the lower portion  12  of the mouse  10 . The exposed wheel  2311  can be turned by the user to adjust the height of the sensing module  13 . 
     Please refer to  FIG. 5  to  FIG. 7 , in conjunction with  FIG. 1  to  FIG. 4 .  FIG. 5  to  FIG. 7  are schematic diagrams showing motions of a mouse adjusting device of the present embodiment. 
     As shown in  FIG. 5 , when the wheel  2311  of the adjusting element  23  has not been turned by the user, the curved face  2211  of the block portion  221  of the sensor carrier  22  abuts the middle of the slanted face  2111  of the ramp portion  211  of the slidable base  21 . At this moment, the sensing module  13  accommodated by the sensor carrier  22  is positioned at a predetermined height. 
     As shown in  FIG. 6 , when the user turns the wheel  2311  of the adjusting element  23  such that the drive screw  231  rotates in a first rotating direction R 1  (i.e. a clock-wise direction) relative to the drive nut  232 , the drive nut  232  at the slidable base  21  is driven to move in a first direction S 1  (i.e. leftward) along the direction of the axis of the drive screw  231 , thereby driving the ramp portion  211  to move horizontally with the slidable base  21  in the first direction S 1 , in turn driving the block portion  221  abutting the slanted face  2111  of the ramp portion  211  to move upward along the slanted face  2111  through the elastic force provided by the elastic units  223 , thereby driving the sensor carrier  22  and the sensing module  13  accommodated thereon to move upward. 
     As shown in  FIG. 7 , when the user turns the wheel  2311  of the adjusting element  23  such that the drive screw  231  rotates in a second rotating direction R 2  (i.e. a counter clock-wise direction) relative to the drive nut  232 , the drive nut  232  at the slidable base  21  is driven to move in a second direction S 2  (i.e. rightward) along the direction of the axis of the drive screw  231 , thereby driving the ramp portion  211  to move horizontally with the slidable base  21  in the second direction S 2 , in turn driving the ramp portion  211  to press the block portion  221  abutting the slanted face  2111  thereof and drive the block portion  221  to move downward along the slanted face  2111  of the ramp portion  211  through the elastic force provided by the elastic units  223 , thereby driving the sensor carrier  22  and the sensing module  13  accommodated thereon to move downward. 
     The drive screw  231  of the present embodiment can rotate in the first or second rotating direction S 1 , S 2  with respect to the drive nut  232 , driving the slidable base  21  to move along the direction of the axis of the drive screw  231  horizontally in the first or second directions S 1 , S 2  with respect to the sensor carrier  22 . The curved face  2211  of the block portion  221  of the sensor carrier  22  slidably abuts the slanted face  2111  of the ramp portion  211 , such that when the block portion  221  and the ramp portion  211  slide with respect to each other, the sensor carrier  22  moves with respect to the slidable base  21  vertically upward or downward, thereby adjusting the height of the sensing module  13 . 
       FIG. 8  shows another embodiment of a mouse adjusting device of the present disclosure. The adjusting device  20  of the mouse  10  of the present embodiment is substantially the same as that of the previous embodiment (as shown in  FIG. 1  to  FIG. 4 ), with the main difference lying in that the adjusting device  20  further includes a control circuit board  24  and a pressure sensor  25  disposed at the control circuit board  24 . The pressure sensor  25  can be for example piezoelectric, piezoresistive, capacitive, or metal thin film sensors, but is not limited to the above. Preferably, the pressure sensor  25  of the present embodiment is a piezoresistive pressure sensor positioned at the underside of the control circuit board  24 . The control circuit board  24  is disposed in the mouse  10  and is positioned above the slidable base  21 . The sensor carrier  22  extends horizontally outward to form an arm  226 . The arm  226  has a pressure spring  2261 , one end of which is disposed at the arm  226 , and another end of which vertically abuts the pressure sensor  25 . Therefore, when the user rotates the wheel  2311  of the adjusting element  23 , such that the sensor carrier  22  moves upward or downward, the pressure spring  2261  is compressed or released as the sensor carrier  22  moves upward or downward, such that the force of the pressure spring abutting the pressure sensor  25  changes, such that the resistivity of the pressure sensor  25  changes, and the control circuit board  24  can determine by the change in resistivity the height of the sensing module  13 , and transmit the result to a display unit (e.g. an LED signal lighting on the mouse, screen, etc.) for display. Therefore, the adjusting device of the present embodiment is a mechanical and electrical device.

All changes, alterations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the present disclosure delineated by the following claims.
