A mouse

Abstract

A mouse includes a housing assembly and an optical engine assembly disposed within the housing assembly. The housing assembly has a sensing window through which light signals emitted and received by the optical engine assembly can pass. The optical engine assembly is movably connected to the housing assembly, partially exposed. The optical engine assembly can move parallel to the sensing window under the action of an external force applied by the user, thereby adjusting its position relative to the sensing window. Based on the movable optical engine assembly, the user can adjust the position of the optical engine assembly within the mouse according to their own grip habits, thereby ensuring that the mouse can meet the user's sensitivity and accuracy requirements when performing operations such as rapid movement and subtle movements, reducing input errors. For example, for players experiencing shooting games, adjusting the optical engine assembly to a position suitable for their grip habits can effectively improve the accuracy of subtle movements such as flick shots.

Description

Technical Field

[0001] This application relates to the field of input device technology, specifically to a mouse. Background Technology

[0002] The optical engine is one of the core components of a mouse. It is primarily responsible for sensing the mouse's position and movement trajectory on the work surface (such as a desktop) using light, providing support for precise user operation and tracking. In current mice, the optical engine is usually fixed in a preset position on the bottom or inside the mouse. This prevents the engine's position from being adaptively adjusted based on the user's grip habits, resulting in a poor user experience in scenarios requiring rapid movement, precise or subtle operations. Utility Model Content

[0003] The main technical problem this application addresses is to provide a mouse that allows users to adjust the position of the optical engine according to their own grip habits, thereby improving the user experience.

[0004] One embodiment provides a mouse, including a housing assembly, a circuit board assembly, and an optical engine assembly. The circuit board assembly and the optical engine assembly are disposed inside the housing assembly and are electrically connected to the optical engine assembly.

[0005] The optical engine assembly is partially exposed outside the housing assembly and is movably connected to the housing assembly; the optical engine assembly can be moved in a direction parallel to the sensing window by an external force applied by the user, so as to adjust the position of the optical engine assembly relative to the sensing window.

[0007] A support base, partially exposed within the housing assembly, is slidably connected to the housing assembly; and

[0008] An optical engine for emitting and receiving light signals is placed on a support base facing the sensing window. The support base can be driven by an external force to move the optical engine in a direction parallel to the sensing window.

[0010] The support base has a force-receiving structure on the side facing the sensing window; the force-receiving structure extends into the sensing window to receive external forces, so that the support base can drive the optical engine to move.

[0011] And / or the optical engine is placed on the side of the support base away from the sensing window; the support base is provided with a clearance window, which is used to avoid or accommodate the sensing end of the optical engine.

[0012] In one embodiment, the bearing base is provided with the force-bearing structure and the avoidance window; the force-bearing structure protrudes from the surface of the bearing base and surrounds the avoidance window.

[0013] In one embodiment, the optical engine assembly includes multiple parallel guide shafts that extend along the moving direction of the optical engine and are fixed to the housing assembly. The support base has guide sleeves on opposite sides in a first direction, and the guide sleeves are slidably fitted onto the corresponding guide shafts. The first direction is perpendicular to the moving direction.

[0014] In one embodiment, one of the housing assembly and the supporting base is provided with a guide rail structure and the other is provided with a sliding groove structure. The guide rail structure and the guide shaft are arranged in parallel in the first direction, and the guide rail structure and the sliding groove structure are slidably connected.

[0015] In one embodiment, the optical engine assembly further includes a pressing member, the housing assembly has a first support and a second support inside, a first end of the guide shaft is inserted into the first support along the first direction, and a second end of the guide shaft overlaps the second support;

[0016] The circuit board assembly is fixedly connected to the housing assembly in such a way that it at least covers the second support; one end of the pressing member abuts against the second end of the guide shaft and the other end abuts against the circuit board assembly to restrict and fix the second end of the guide shaft to the second support.

[0017] In one embodiment, the housing assembly has a limiting baffle inside, which is located on one side or opposite sides of the support base in a first direction. The limiting baffle has a plurality of position slots continuously distributed along the moving direction of the optical engine, and the support base has position protrusions that cooperate with the limiting baffle. The position protrusions can be engaged in any of the position slots to fix the position of the optical engine. The first direction is perpendicular to the moving direction.

[0018] In one embodiment, the optical engine assembly is configured to move along the back-and-forth direction of the mouse under the action of an external force applied by the user.

[0019] In one embodiment, the housing assembly includes a base and a faceplate; the base and faceplate are connected to form an accommodating space for accommodating the circuit board assembly and the optical engine assembly; wherein the sensing window is disposed through the base, the circuit board assembly is fixedly connected to the base, and the optical engine assembly is movably connected to the base in a manner that partially exposes the base.

[0020] The mouse according to the above embodiment includes a housing assembly and an optical engine assembly disposed inside the housing assembly. The housing assembly has a sensing window through which light signals emitted and received by the optical engine assembly can pass. The optical engine assembly is movably connected to the housing assembly in a manner partially exposed outside the housing assembly. The optical engine assembly can move parallel to the sensing window under the action of an external force applied by the user, thereby adjusting the position of the optical engine assembly relative to the sensing window. Based on the movable optical engine assembly, the user can adjust the position of the optical engine assembly in the mouse according to their own grip posture, thereby ensuring that the mouse can meet the user's requirements for mouse sensitivity and accuracy when performing operations such as rapid movement and fine movements, and thus reducing input operation errors. For example, for players experiencing shooting games, by adjusting the optical engine assembly to a position suitable for their own grip habits or posture, the accuracy and sensitivity of fine movements such as flick shots can be effectively improved.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0035] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0036] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0037] Please see Figures 1 to 9 This application provides a mouse, such as a wired optical mouse or a wireless optical mouse, which includes an optical engine assembly 100, a housing assembly 200, a circuit board assembly 300, a function key assembly, and other functional components as needed, which are described in detail below.

[0038] Please see Figures 1 to 4 The housing assembly 200 can be understood as a collection of related components that constitute the overall outline of the mouse. The function key assembly can be understood as a component that allows the user to control the mouse to perform related functions, such as the left mouse button 410, the right mouse button 420, and the mouse scroll wheel 430. The optical engine assembly 100 and the circuit board assembly 300 are both located inside the housing assembly 200, and the optical engine assembly 100 and the circuit board assembly 300 are electrically connected.

[0039] The circuit board assembly 300 can be understood as a collection of related devices that realize all or part of the functions of the mouse. For example, the circuit board assembly 300 includes a main control circuit board 310 and left-click microswitches 320, right-click microswitches 330, scroll wheel encoders 340, etc., which are disposed on the main control circuit board 310. The optical engine assembly 100 is mainly used to sense the position and movement trajectory of the mouse on the working interface through light. For example, the optical engine assembly 100 includes light-emitting diodes for emitting light signals, optical sensors for collecting light signals, and lens assemblies disposed on the light signal propagation path. The light-emitting diodes, optical sensors, etc. can be electrically connected to the circuit board assembly 300 (specifically, the main control circuit board 310).

[0040] Regarding the overall structural architecture of the mouse, a sensing window 200a can be provided on the housing assembly 200 corresponding to the position of the optical engine assembly 100. This sensing window 200a allows the optical engine to transmit and receive light signals. In the front-back direction of the mouse, the mouse wheel 430 is arranged through the top surface of the front end of the housing assembly 200 and is connected to the wheel encoder 340 in the circuit board assembly 300. The left mouse button 410 and the right mouse button 420 are exposed on the housing assembly 200 and are symmetrically arranged about the front end of the housing assembly 200 with respect to the mouse wheel 430. Furthermore, the left mouse button 410 and the right mouse button 420 are respectively connected to the left button micro switch 320 and the right button micro switch 330. It should be noted that the front-back direction here refers to the part of the mouse that supports the fingers (such as the index finger and middle finger) when the user holds the mouse, which is considered the front, and the part of the mouse that supports the palm is considered the back.

[0041] It should be noted that those skilled in the art should understand the working principle of the mouse in cooperation with the optical engine assembly 100, the circuit board assembly 300, and the function key assembly. For example, the left mouse button 410 can cause the main control circuit board 310 to generate and output corresponding signals by pressing and releasing the left button micro switch 320. Furthermore, the main control circuit board 310 can calculate the mouse's moving distance, direction, and trajectory by analyzing changes in the light signal, thereby ultimately determining the cursor's position. Therefore, the working principle of the mouse provided in this application embodiment will not be described in detail here.

[0042] In some embodiments, please refer to Figure 1 and Figure 2 The housing assembly 200 includes a front shell 210 and a base 220. The front shell 210 is a housing structure with a certain volume space. For example, when the mouse is held in the hand, the front shell 210 is an ergonomic curved shell structure that can adapt to the shape of the palm. In the height direction of the mouse, the base 220 can be fixedly set at the bottom of the front shell 210 by means of locking, snap-fitting, welding, etc., so that the base 220 and the front shell 210 together enclose the internal space (i.e., the accommodating space) of the housing assembly 200.

[0043] Correspondingly, the optical engine assembly 100 and the circuit board assembly 300 are disposed on the base 220, the sensing window 200a is disposed through the base 220 along the height direction of the mouse, the mouse scroll wheel 430 is disposed through the front shell 210, and the left mouse button 410 and the right mouse button 420 are disposed on the outside of the shell assembly 200, covering the front end of the front shell 210. Of course, the left mouse button 410, the right mouse button 420 and the front shell 210 can be of a single integrated structure.

[0044] In practice, the left mouse button 410, the right mouse button 420, and the faceplate 210 can be made of magnesium alloy or carbon fiber materials, and manufactured through processes such as die casting, stamping, grinding, passivation, and spraying. The base 220 can be made of magnesium alloy or carbon fiber materials, similar to the faceplate 210, or it can be made of plastic or other materials through processes such as injection molding and 3D printing.

[0045] On the one hand, by utilizing the high strength, light weight, wear resistance, impact resistance, and good processability of magnesium alloy or carbon fiber materials, not only can the weight of the mouse be reduced and the overall structural strength of the mouse be improved, which is conducive to realizing the lightweight and simplified structural design of the mouse, but also can create conditions for improving the overall texture and aesthetic appearance of the mouse. On the other hand, by using the base 220 as the mounting carrier for functional components such as the circuit board assembly 300 and the optical engine assembly 100, the overall structural complexity of the mouse can be effectively reduced, making it easier to assemble, disassemble, and maintain the mouse.

[0046] The following section mainly introduces the optical engine component 100 and its related structures.

[0047] Please see Figures 2 to 9 The optical engine assembly 100 is movably connected to the interior of the housing assembly 200, and at least part of the optical engine assembly 100 is exposed outside the housing assembly 200; for example, the optical engine assembly 100 is slidably connected to the base 220, and at least part of the optical engine assembly 100 is exposed outside the base 220 via the sensing window 200a. By applying a force (e.g., a pushing or pulling force) to the optical engine assembly 100, the user can move the optical engine assembly 100 in a direction parallel to the sensing window 200a, such as along the mouse's front-back direction, left-right direction, or other directions intersecting or perpendicular to the mouse's height direction, thereby adjusting the position of the optical engine assembly 100 relative to the sensing window 200a. That is, the optical engine assembly 100 is configured to be able to translate within a plane at least perpendicular to or intersecting with the mouse's height direction under the action of an external force applied by the user.

[0048] For example, please refer to Figure 3 and Figure 4The optical engine assembly 100 includes a support base 110 and an optical engine 120. The support base 110 is partially exposed within the housing assembly 200 and is slidably connected to it. For example, a sensing window 200a extends through the base 220 along the height of the mouse, and a portion of the support base 110 is exposed through the sensing window 200a into the base 220. A sliding guide structure parallel to the sensing window 200a is provided between the support base 110 and the base 220. This sliding guide structure can be positioned along the mouse's front-back or left-right directions to establish a sliding connection between the support base 110 and the base 220. Thus, the user can apply external forces such as pushing or pulling to the support base 110 through the structural space provided by the sensing window 200a, thereby causing the support base 110 to move relative to the base 220 in a direction parallel to the sensing window 200a. The term "direction parallel to the sensing window 200a" can be understood as a direction parallel to the plane containing the sensing window 200a.

[0049] Regarding the optical engine 120, it can be understood as a functional structure formed by the combination of light-emitting diodes, lens assemblies, and optical sensors, etc. Its main function is to emit and receive light signals to sense the mouse's position and movement trajectory in cooperation with the circuit board assembly 300. Specifically, the optical engine 120 is fixedly mounted on the support base 110 facing the sensing window 200a, and is electrically connected to the circuit board assembly 300 (specifically, the main control circuit board 310). When the support base 110 moves under the force applied by the user, it can move the optical engine 120 synchronously in a direction parallel to the sensing window 200a, thereby adjusting or changing the position of the optical engine 120 within the mouse.

[0050] For example, the optical engine assembly 100 may omit the support base 110. By sliding the optical engine 120 to the housing assembly 200 and exposing part of the optical engine 120 through the sensing window 200a to the housing assembly 200, it is also convenient for the user to drive the optical engine 120 to move by applying force to it. Alternatively, the support base 110 can also be understood as part of the optical engine 120. For example, the support base 110 refers to a structural component that integrates devices such as light-emitting diodes and optical sensors to form the optical engine 120.

[0051] Thus, by adjusting the position of the optical engine component 100, the sensing end of the optical engine 120 (i.e., the component or part in the optical engine 120 used to receive and transmit light signals) can be positioned within the mouse to match the user's grip habits or posture. This ensures that the user can obtain appropriate sensitivity and accuracy when operating the mouse, reducing errors in mouse input. For example, shooting game players can adjust the position of the optical engine component 100 along the front-back direction of the mouse according to their personal grip habits or posture. This helps users perform large-scale movements or precise, subtle operations in the game, such as quick turns, crosshair movement, and flick shots. Furthermore, because the position of the optical engine component 100 is adapted to the user's grip habits or posture, it improves the accuracy and sensitivity of the user's corresponding actions, thereby enhancing the overall mouse user experience.

[0052] It should be noted that, Figure 3 The bold dashed line with double arrows indicates the direction of movement of the optical engine assembly 100.

[0053] In some embodiments, please refer to Figure 4 and Figures 6 to 9 The support base 110 is positioned facing the sensing window 200a. The optical engine 120 is placed on the side of the support base 110 away from the sensing window 200a. The support base 110 has a clearance window 111 corresponding to the sensing end of the optical engine 120. The sensing end of the optical engine 120 can extend into and be accommodated within the clearance window 111 or be exposed on the support base 110 through the clearance window 111. When the optical engine assembly 100 is installed in the housing assembly 200, the support base 110 can avoid the sensing window 200a and the sensing end of the optical engine 120 based on the clearance window 111, so that the light signal emitted by the optical engine 120 can be output through the sensing window 200a and the light signal reflected by the mouse working interface can be incident on the optical engine 120 through the sensing window 200a.

[0054] Meanwhile, a force-bearing structure 112 is provided on the surface of the support base 110 facing the sensing window 200a. The force-bearing structure 112 extends into the sensing window 200a or is exposed outside the housing assembly 200 through the sensing window 200a. For example, the sensing window 200a is disposed through the base 220, the force-bearing structure 112 protrudes from the surface of the support base 110 along the height direction of the mouse and extends into the sensing window 200a, and the force-bearing structure 112 surrounds the window 111.

[0055] On the one hand, by placing the optical engine 120 on the side of the support base 110 away from the sensing window 200a, it is beneficial to reduce the overall size of the optical engine assembly 100 and reduce the occupation of the limited space inside the housing assembly 200, so as to provide structural support for the smooth movement of the optical engine 120. On the other hand, based on the structural form of the force-bearing structure 112 extending into the sensing window 200a or exposed through the sensing window 200a in the housing assembly 200, it is convenient for the user to apply a pushing or pulling force to the support base 110 through the force-bearing structure 112, so as to cause the support base 110 to drive the optical engine 120 to move synchronously, thereby realizing the adjustment of the position of the optical engine 120.

[0056] On the other hand, when the force-bearing structure 112 is arranged to surround the window 111 and extend into the sensing window 200a, the movement stroke of the optical engine 120 can be limited by the force-bearing structure 112. For example, when the user pushes the optical engine assembly 100 forward in the back-and-forth direction of the mouse to its limit position, the force-bearing structure 112 will abut against the front sidewall of the sensing window 200a (see [link]). Figure 8 This prevents the optical engine assembly 100 from moving forward further; instead, the force-bearing structure 112 abuts against the rear sidewall of the sensing window 200a (see [link]). Figure 9 This prevents the optical engine component 100 from moving backward; thus, it limits the movement of the optical engine component 100, ensuring that the optical engine 120 is within a range that can perceive the position and movement trajectory of the mouse in real time.

[0057] It should be noted that, Figure 8 and Figure 9 The bold dashed line with an arrow indicates the direction of movement of the optical engine assembly 100.

[0058] In other embodiments, the avoidance window 111 may be omitted from the support base 110. In this case, the support base 110 may be slidably connected to the base 220 or to the face shell 210. The optical engine 120 may be fixed on the side of the support base 110 facing the sensing window 200a. The force-bearing structure 112 may be set on the support base 110 or on the optical engine 120. Of course, the structural relationship between the support base 110 and the optical engine 120 may also adopt other suitable forms to achieve the purpose of the support base 110 driving the optical engine 120 to move synchronously in a direction parallel to the sensing window 200a. These will not be elaborated here.

[0059] In some embodiments, please refer to Figures 3 to 7The optical engine assembly 100 also includes a guide shaft 130, which can establish a sliding connection between the support base 110 and the housing assembly 200, and can also constrain the optical engine assembly 100 to the housing assembly 200.

[0060] Specifically, the guide shaft 130 extends along the moving direction of the optical engine 120 and is fixed to the housing assembly 200. For example, the guide shaft 130 extends along the front-back direction of the mouse and is fixed to the base 220. The number of guide shafts 130 is set to two, and the two guide shafts 130 are arranged on opposite sides of the support base 110 in a first direction. The first direction refers to the direction perpendicular to the moving direction of the optical engine 120 (e.g., the left-right direction of the mouse). Correspondingly, the support base 110 is provided with guide sleeves 113 on opposite sides in the first direction, and the guide sleeves 113 are slidably sleeved on the corresponding guide shaft 130.

[0061] Thus, by utilizing the sliding connection between the guide shaft 130 and the guide sleeve 113, the support base 110 (along with the optical engine 120) can be constrained and limited to the housing assembly 200 (specifically, the base 220), and a sliding connection can be established between the support base 110 and the housing assembly 200. This allows the user to adjust the position of the optical engine 120 by moving the support base 110 along the guide shaft 130 according to their own mouse-holding habits or postures. Of course, the number of guide shafts 130 can also be set to three, four, or more, depending on the internal structural layout of the mouse.

[0062] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 7 A sliding guide structure is provided between the housing assembly 200 (e.g., base 220) and the support base 110. The sliding guide structure includes a guide structure 221 and a groove structure 114 that are slidably connected. The guide structure 221 is arranged in parallel with the guide shaft 130. For example, the guide structure 221 is located between two guide shafts 130 in the first direction. The number of guide structures 221 can be two, three, or more. The groove structure 114 is located on the side of the support base 110 away from the optical engine 120 in the height direction of the mouse.

[0063] By utilizing the sliding fit between the guide rail structure 221 and the slide groove structure 114, a sliding connection can also be established between the support base 110 and the housing assembly 200, and the internal space of the housing assembly 200 can be fully utilized. With the cooperation of the guide shaft 130 and the guide bushing 113, not only can the support base 110 carry the optical engine 120 to move more smoothly, but the structural compactness and stability between the support base 110 and the housing assembly 200 can also be enhanced, preventing the support base 110 from shaking or swaying relative to the housing assembly 200 during movement, thus providing support for the precise and stable adjustment of the position of the optical engine 120.

[0064] It is understandable that the guide rail structure 221 and the slide rail structure 114 can also be interchanged, that is, the guide rail structure 221 is set on the bearing base 110, and the slide rail structure 114 is set on the housing assembly 200 (e.g., base 220).

[0065] In other embodiments, the guide shaft 130 may be omitted. In this case, the guide rail structure 221 and the slide groove structure 114 may also adopt a sliding connection structure such as a T-shaped or dovetail groove. Alternatively, the bearing base 110 may be connected to the housing assembly 200 through a linear module or the like. In this way, the bearing base 110 can be constrained and limited on the housing assembly 200, and the bearing base 110 can carry the optical engine 120 to move smoothly and steadily.

[0066] In some embodiments, please refer to Figures 3 to 5 The optical engine assembly 100 also includes a pressing member 140. Correspondingly, the housing assembly 200 has a first support 222 and a second support 223 inside. The first support 222 and the second support 223 are used to cooperate with the pressing member 140 and the circuit board assembly 300 to restrict and fix the guide shaft 130 on the housing assembly 200, and to provide support for the bearing base 110 to slide and engage the guide shaft 130 through the guide sleeve 113.

[0067] Specifically, both the first support 222 and the second support 223 protrude from the inner surface of the housing assembly 200, such as the inner surface of the base 220; wherein, the first support 222 has a plug hole arranged along the moving direction of the optical engine 120, and the second support 223 has a joint arranged along the height direction of the mouse; the first end of the guide shaft 130 is inserted into the first support 222 through the plug hole, and the second end of the guide shaft 130 opposite to the first end is connected to the second support 223 through the joint. The circuit board assembly 300 (specifically, the main control circuit board 310) is fixedly connected to the housing assembly 200 (e.g., fixed to the base 220 by screws or other fasteners) in a manner that at least covers the second support 223. The pressing member 140 is clamped between the second support 223 and the circuit board assembly 300, such that one end of the pressing member 140 abuts against the circuit board assembly 300 in the mouse height direction, and the other end abuts against the second end of the guide shaft 130, thereby restricting and fixing the second end of the guide shaft 130 to the second support 223. Exemplarily, the pressing member 140 may be a structural component made of a flexible material such as silicone.

[0068] Thus, by using the first support 222 and the second support 223 to provide structural support for the guide shaft 130, the guide shaft 130 can be suspended and fixed inside the housing assembly 200. This allows the bearing base 110 to slide along the guide shaft 130 while the guide sleeve 113 is fitted onto the guide shaft 130. Simultaneously, by inserting one end of the guide shaft 130 into the first support 222 and restricting the other end to the second support 223 by the pressure exerted by the circuit board assembly 300 on the pressing member 140, the optical engine assembly 100 and the circuit board assembly 300 can be conveniently and quickly assembled into the housing assembly 200 during mouse assembly. Furthermore, this effectively reduces the number of screws and other fasteners, maximizing the utilization of the mouse's internal structure.

[0069] For example, please refer to Figure 5 During mouse assembly, the support base 110 is first placed on the guide shaft 130 through the guide sleeve 113. Then, the first end of the guide shaft 130 is inserted into the first support 222, and the second end is attached to the second support 223. Subsequently, the pressing member 140 is placed on the second support 223. Finally, the circuit board assembly 300 is installed, with the circuit board assembly 300 stacked on the pressing member 140. During the process of fastening the circuit board assembly 300 to the housing assembly 200 with screws and other fasteners, a pressing force is applied to the pressing member 140. Thus, while completing the installation of the circuit board assembly 300, the guide shaft 130 is fixed to the housing assembly 200.

[0070] In some embodiments, please refer to Figure 3, Figure 4 , Figure 6 and Figure 7 The housing assembly 200 is also provided with a limiting baffle 224 inside. The limiting baffle 224 is located on one side or opposite sides of the support base 110 in the first direction, and the limiting baffle 224 is provided with a plurality of position slots continuously distributed along the moving direction of the optical engine 120. Correspondingly, the support base 110 is provided with a position protrusion 115 on the side of the supporting base 110 facing the limiting baffle 224 in the first direction. The position protrusion 115 can be locked into any position slot to fix the position of the optical engine 120.

[0071] Specifically, when the user applies force to push the support base 110 to move, the gear shift protrusion 115 and the limit baffle 224 always abut against each other; when the external force is removed and the support base 110 stops moving, the gear shift protrusion 115 will lock into the corresponding gear shift slot, thus fixing the position of the optical engine 120 and ensuring that the optical engine 120 will not move unexpectedly after the user adjusts the position of the optical engine 120.

[0072] It should be noted that, based on the principle that the optical engine component 100 can move under the action of external force applied by the user, the optical engine component 100 can also adopt other suitable structural forms. For example, the support base 110 can be designed with reference to existing multi-dimensional motion platforms.

[0073] For example, the support base 110 can adopt a two-dimensional motion platform structure, which is set to carry the optical engine 120 to move along the front-back and left-right directions of the mouse under the action of external force applied by the user. This makes it easier for the user to adjust the position of the optical engine 120 with more freedom (such as moving forward and backward, moving left and right, etc.) according to their own mouse holding habits or posture.

[0074] For example, the support base 110 can be a three-dimensional motion platform. While the support base 110 can carry the optical engine 120 to move in a direction parallel to the sensing window 200a, the user can adjust the static height of the optical engine 120 (i.e., adjust the height distance between the optical engine 120 and the mouse working interface) by adjusting the position of the optical engine 120 in the height direction, thereby adjusting the sensitivity of the mouse itself.

[0075] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
