Description

Technical Field

[0001] The present invention relates to the technical field of wireless mice, and in particular to a lightweight mouse housing and a lightweight wireless mouse. Background Art

[0002] At present, the mouse occupies a very important position in people's daily work and gaming entertainment, and is used very frequently. In order to reduce the damage to the hand and wrist caused by frequent mouse operation, the lightweight development trend of the mouse is very obvious.

[0003] Based on practicality and ergonomics, the external dimensions and internal components of mice of the same level will not change much, so the lightweight design of the mouse is mostly to consider reducing the weight of the shell, such as the recently disclosed lightweight mouse patent documents CN2024301704849, CN2024300308337, CN202322720282X, etc., all of which form hollows on the upper surface of the shell to achieve the purpose of reducing the weight of the shell and achieving lightweight. In actual applications, since the hollows are located on the upper side, dust and foreign matter can easily fall into the mouse through the hollows, so the position and number of hollows are subject to certain restrictions. At the same time, in order to reduce the impact of the outside world on the internal components of the mouse, this type of mouse has certain requirements for the humidity and air particle content of the use environment, as well as the operator's usage habits, and its scope of application and audience is limited. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a lightweight mouse shell and a lightweight wireless mouse, and uses a smaller bottom cover to replace the traditional full-coverage mouse bottom shell, which can significantly reduce the weight of the mouse shell, and the probability of foreign matter such as external liquid, water vapor, and particles entering the inside of the mouse through it is very low. At the same time, because the bottom cover protects the sensor cover, an important component that affects the mouse control sensitivity, on its inner side, the influence of external factors on the mouse control sensitivity can be further avoided. It has been verified that the weight of a wireless mouse using a lightweight mouse shell can be reduced by 20%, the lightweight effect is obvious, and there is no obvious change in the various operating performances of the mouse, which meets the design expectations, and breaks the conventional design idea that the mouse bottom shell needs to completely wrap the internal components, and has great promotion value.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is as follows:

[0006] A lightweight mouse shell, the mouse shell comprising an upper cover and a bottom cover, the upper cover is formed with a plurality of mounting holes and weight-reducing holes, each of the mounting holes is used to install or avoid function buttons or connectors, and the middle of the bottom cover is provided with an avoidance hole for avoiding a sensor inside the mouse; wherein:

[0007] A plurality of positioning posts extending toward the bottom cover are arranged on the inner wall of the upper cover, and the plurality of positioning posts can cooperate with locking screws to fix the plurality of circuit boards on the inner side of the upper cover, and a plurality of vertically extending support posts are formed on the periphery of the plurality of positioning posts, and one end of each support post extends to the inner wall of the upper cover, and the other end extends to below the lower end of the upper cover, and the lower end surfaces of all the support posts are coplanar;

[0008] The bottom cover is detachably fixed to the lower end of the circuit board provided with the sensor, and its contour edges all fall on the inner side of the projection of the contour edges of the upper cover and cover the periphery of the sensor, and when the support column is placed on a support table, the lower end surface of the bottom cover is located above the support table.

[0009] As a further elaboration of the above technical solution:

[0010] In the above technical solution, a guide protrusion and a plurality of positioning protrusions are formed at the end of the bottom cover facing the upper cover: the upper end surfaces of the plurality of positioning protrusions are coplanar and can all abut against one of the circuit boards, and a plurality of positioning protrusions are formed with positioning hole columns that are adapted to the positioning hole grooves on the circuit board; the height of the guide protrusion is smaller than the height of the positioning protrusion, and it forms an annular structure or a "U"-shaped structure and can be covered on the periphery of the sensor.

[0011] A technical solution adopted by the present invention is as follows:

[0012] A lightweight wireless mouse, comprising a mouse housing and a plurality of buttons mounted thereon, a plurality of circuit boards and components mounted therein, wherein the mouse housing is the lightweight mouse housing described in the above technical solution, a battery is fixed between a plurality of the positioning posts, the battery is electrically connected to each of the circuit boards, the bottom cover is also provided with a control hole groove for avoiding a power switch, the power switch is mounted beside the sensor and electrically connected to one of the circuit boards.

[0013] As a further elaboration of the above technical solution:

At the same time, because the bottom cover protects the sensor cover, an important component that affects the control sensitivity of the mouse, on its inner side, the impact of external factors on the control sensitivity of the mouse can be further avoided; it has been verified that the weight of a wireless mouse using a lightweight mouse shell can be reduced by 20%, the lightweight effect is obvious, and there is no obvious change in the various operating performances of the mouse, which meets the design expectations, and breaks the conventional design idea that the mouse bottom shell needs to completely wrap the internal components, and has great promotion value.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, "several" and "multiple" mean two or more, unless otherwise clearly and specifically defined. In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In this application, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature can include the first and second features being in direct contact, or it can include the first and second features not being in direct contact but being in contact through another feature between them.

[0027] like Figure 1-3 As shown, a lightweight mouse shell includes an upper cover 10 and a bottom cover 20. The upper cover 10 is formed with a plurality of mounting holes 1 and weight-reducing holes 2. Each mounting hole 1 is used to install or avoid function buttons or connectors. The middle of the bottom cover 20 is provided with an avoidance hole 8 for avoiding the sensor 30 inside the mouse; wherein:

[0028] A plurality of positioning columns 3 extending toward the bottom cover 20 are provided on the inner wall of the upper cover 10. The plurality of positioning columns 3 can cooperate with locking screws to fix the plurality of circuit boards 40 on the inner side of the upper cover 10. A plurality of vertically extending support columns 4 are formed around the periphery of the plurality of positioning columns 3. One end of each support column 4 extends to the inner wall of the upper cover 10, and the other end extends to below the lower end of the upper cover 10, and the lower end surfaces of all the support columns 4 are coplanar.

[0029] The bottom cover 20 is detachably fixed to the lower end of the circuit board 40 provided with the sensor 30, and its contour edges all fall on the inner side of the projection of the contour edges of the upper cover 10 and cover the periphery of the sensor 30, and when the support column 4 is placed on a supporting table, the lower end surface of the bottom cover 20 is located above the supporting table.

[0030] The present invention uses a smaller bottom cover 20 to replace the traditional full-coverage mouse bottom shell, which can form a larger blank area at the bottom of the mouse, which can significantly reduce the mass of the mouse shell. In addition, since this area is located between the bottom of the mouse and the mouse pad under normal conditions, the probability of foreign matter such as external liquids, water vapor, and particles entering the interior of the mouse through it is very low. At the same time, since the bottom cover 20 covers and protects the sensor 30, an important component that affects the mouse control sensitivity, on its inner side, the influence of external factors on the mouse control sensitivity can be further avoided.

[0031] Furthermore, a guide protrusion 5 and a plurality of positioning protrusions 6 are formed at the end of the bottom cover 20 facing the upper cover 10: the upper end surfaces of the plurality of positioning protrusions 6 are coplanar and can all rest on a circuit board 40, and a plurality of positioning protrusions 6 are formed with positioning hole columns 601 adapted to the positioning hole grooves on the circuit board 40; the height of the guide protrusion 5 is less than the height of the positioning protrusion 6, and it forms an annular structure or a "U"-shaped structure and can be covered on the periphery of the sensor 30.

[0032] It can be understood that the relatively short guide protrusion 5 can reserve a gap between the sensor 30 and the bottom cover 20, which, together with a number of positioning protrusions 6, can ensure that the sensor 30 maintains moderate air connectivity with the outside world after the bottom cover 2 and the circuit board 30 are assembled and fixed, thereby facilitating the disassembly and assembly of the bottom cover 2 and the circuit board 30.

[0033] like Figure 4-6 As shown, an application embodiment of the above invention is a lightweight wireless mouse, which includes a mouse housing and a plurality of buttons 50 mounted thereon, a plurality of circuit boards 40 mounted therein, and components. The mouse housing is the lightweight mouse housing in the above embodiment, a battery 60 is fixed between the plurality of positioning columns 3, and the battery 60 is electrically connected to each circuit board 40. A control hole 7 for avoiding a power switch 70 is also provided on the bottom cover 20. The power switch 70 is mounted next to the sensor 30 and is electrically connected to a circuit board 40.

[0034] The connection structure between the internal components of the mouse and its working principle belong to the prior art and will not be described in detail here.

[0035] Specifically, a left button 51 , a right button 52 , a side button 53 , a scroll wheel 54 , a DPI button 55 and a connection port 56 , which are electrically connected to the circuit board 40 , are respectively embedded in the plurality of mounting hole slots 1 .

[0036] Furthermore, a foot pad 80 is fixedly disposed on each support column 4 , and the lower end surfaces of the plurality of foot pads 80 are coplanar and extend below the lower end surface of the bottom cover 20 .

[0037] According to measurement, the weight of a conventional wireless mouse of this level is generally about 50g. This embodiment adopts a lightweight mouse shell, and the weight can be reduced to 40g, which can be reduced by 20%, and the lightweight effect is obvious.

[0038] After testing and verification, when the distance from the wireless device is 40cm, the Polling Rate of the wireless mouse in this embodiment can still reach more than 90% of the maximum value, and when the distance from the wireless device is 80cm, the Polling Rate can still reach more than 80% of the maximum value, and its response speed fully meets the design requirements. The specific test results are shown in the following table.

[0039]

[0040] In addition, it has been verified by special testing equipment that during the program running on the host, the response time of the wireless mouse and the program remains roughly stable. The response curve is as follows: Figure 7 shown.

[0041] The above test results verify that the wireless mouse of this embodiment using a lightweight mouse shell is 20% lighter than a conventional wireless mouse, with a significant lightweight effect. The operating performance of the mouse has no significant change and meets the design expectations. It also breaks the conventional design idea that the bottom shell of the mouse must completely wrap the internal components, and has great promotion value.

[0042] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
