Description

Technical Field

[0001] The utility model belongs to the technical field of computer input equipment, and more specifically relates to a lightweight mouse with an improved structure. Background Art

[0002] The mouse is one of the most commonly used computer input devices. It has been decades since its introduction, but its structure has not changed much. Common mice are generally made of plastic material, including an outer shell, an inner shell and a bottom plate, and the inner shell is buckled with the bottom plate; the outer shell is composed of an upper cover, a left cover, and a right cover, and the upper cover, left and right side covers are all installed on the inner shell; the front end of the upper cover can be elastically deformed and used as a left and right button cover, and a circuit board is provided on the bottom plate, and a micro switch is provided on the circuit board. Pressing the left and right button covers can trigger the micro switch, thereby realizing the input function. This type of mouse has a more complex structure. Although the plastic material is easy to shape, it has poor support. In order to achieve higher support, the shell thickness can only be increased, and it is difficult to meet the demand for lightweight. With the development of the e-sports industry, professional gamers need a lightweight mouse with good support performance.

[0003] In order to meet this demand, the industry has proposed a lightweight mouse made of alloy materials. The alloy materials are thin and light while achieving good support. However, although the alloy materials are thin and light, it is difficult to form the complex positioning and connection structures (used to install parts, fix circuit boards or connect to the base plate, etc.) required for the mouse shell directly on the surface of the alloy materials by casting or stamping. This will lead to the following problems: First, the positioning or connection structure of each mouse shell must be completed by manually operated CNC equipment, which has high labor costs; second, the yield rate is low. Once the positioning or connection structure breaks or the position and size are inaccurate during the casting or stamping process, the entire mouse shell will be directly scrapped, resulting in high manufacturing costs; finally, in order to improve the yield rate, this alloy shell generally reduces the positioning or connection structure as much as possible, which is difficult to adapt to the development trend of multi-button and multi-function mice, and will also lead to many problems such as low structural stability after assembly. Utility Model Content

[0004] The purpose of the utility model is to provide a lightweight mouse, which can be more accurately provided with a variety of positioning or connection structures, is easy to process, and has a high yield rate.

[0005] In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: to provide a mouse, including a base plate and a shell installed on the base plate, the base plate is provided with a circuit board, and its characteristics are: the shell includes an upper cover, a front cover, a left cover and a right cover, the upper cover, the front cover, the left cover and the right cover are integrally formed of metal material, the inner surface of the shell is partially rough, and the mouse also includes a positioning structure that can be used to connect the shell and the base plate, and the positioning structure is formed on the rough surface by injection molding.

[0006] After adopting such a structure, a shell is formed by casting with metal material, and the high hardness of the metal material is used to create a thin mouse shell to achieve lightweight mouse. A rough surface is formed on the inner surface of the metal shell to roughen the smooth inner surface of the shell, so that the positioning structure can be directly molded on the inner surface of the metal shell by injection molding. The positioning structure made of plastic material can improve the connection accuracy between the mouse shell and the bottom plate. Compared with the prior art, the mouse of the present application greatly reduces the uncertainty and high scrap rate of manual processing in the production process. Even if the injection molding fails once, the process can be repeated without the entire mouse shell being scrapped. In addition, the injection molding positioning structure can be set according to the internal structure of the mouse, and the form is diverse and suitable for a variety of mouse structures.

[0007] Specifically, the rough surface is formed on the inner surface of the shell by laser or corrosion. The rough surface is formed by roughening the metal surface by laser impact or chemical corrosion process, which can improve the bonding force between metal and plastic, so that the complex positioning structure can be directly injection molded on the inner surface of the mouse shell and is not easy to fall off, which facilitates the connection between the shell and the positioning structure and improves the connection stability.

[0008] Preferably, the mouse comprises a left button, a right button, a scroll wheel and a button mounting structure for mounting the left and right buttons and the scroll wheel, and the button mounting structure is formed by extending the positioning structure.

[0009] Further preferably, the upper cover is provided with an opening for accommodating the left and right buttons and the roller, the button mounting structure includes a left button mounting portion, a right button mounting portion and a roller mounting hole located between the left button mounting portion and the right button mounting portion, and the left button, right button and roller are respectively correspondingly mounted in the left button mounting portion, the right button mounting portion and the roller mounting hole.

[0010] A further improvement of the above technical solution, the positioning structure is distributed on the upper cover, the front cover, the left cover and the right cover, the opening of the upper cover extends to the edge of the front cover, and the key installation structure extends from the positioning structure located on the upper cover to the opening direction and is connected to the positioning structure located on the front cover. In this solution, the upper cover opening does not extend to the left and right covers, that is, there are still partial structures of the upper cover on the left and right sides of the opening. At this time, the key installation structure is mainly formed by extending from the positioning structure in the upper cover, and the supporting performance is better.

[0011] Another improvement is that the positioning structure is distributed on the upper cover, the front cover, the left cover and the right cover, the opening of the upper cover extends to the edges of the front cover, the left cover and the right cover respectively, and the button installation structure extends from the positioning structure located on the upper cover to the opening direction and is connected to the positioning structure located on the front cover, the left cover and the right cover. In this solution, the button installation structure occupies the entire front end of the upper cover, is suitable for buttons of larger size, and has better elasticity.

[0012] Specifically, the mouse includes two micro switches and two pressing components, one button corresponds to a pressing component and a micro switch, both micro switches are electrically connected to the circuit board, and the two pressing components are used to trigger the corresponding micro switches when the left and right buttons are pressed.

[0013] More specifically, the two pressing assemblies each include an elastic plate and a pressing plate mounted on the elastic plate, one end of the elastic plate is connected to the positioning structure located on the upper cover, and the other end is mounted on the button mounting structure, and the pressing plate triggers the corresponding micro switch when the button is pressed. It is precisely because the present application adopts the injection molding method that the positioning structure in the upper cover can meet diverse needs, so that one end of the elastic plate can be directly mounted on the positioning structure, and the other end can be relatively displaced or deformed to realize the triggering function.

[0014] Preferably, the two micro switches each include a contact, and a top block is provided at a position corresponding to the contact on each pressing plate, and when the left or right button is pressed, the pressing plate can push the corresponding top block to move downward and drive the contact.

[0015] Further preferably, the mouse further comprises a side key circuit board, the left side cover is provided with at least one side key hole, the positioning structure and the key installation structure located on the upper cover respectively extend at least one positioning column downward, and the side key circuit board is installed on the positioning column. The installation of the side key circuit board on these positioning columns can make the internal structure of the mouse more compact and miniaturize the mouse.

[0028] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] All drawings only reveal the parts closely related to the utility model, rather than the entire structure of the key switch. Without affecting the realization of the utility model, when the utility model uses the words "provided with", "set", "connected", "installed", "connected" and "fixed" in the claims and the specification to describe the relationship between two parts, devices or structures, they all cover the implementation of one-piece molding, unless otherwise specified in the utility model; when the utility model uses "a" before a feature, it only means that the feature appears for the first time, and does not mean the meaning of quantifiers such as one or one.

[0030] See also Figure 1 , 2 , 3, 4 and 11, the mouse 100 provided by the utility model is now described. The mouse 100 includes a bottom plate 20 and a shell 10, the shell 10 is installed on the bottom plate 20, a circuit board 30 is provided on the bottom plate 20, and the circuit board 30 is used to electrically connect with other components, and the shell 10 includes an upper cover 11, a front cover 12, a left cover 13 and a right cover 14, that is, the upper cover 11, the front cover 12, the left cover 13 and the right cover 14 together enclose the shell 10 of the mouse 100, and the upper cover 11, the front cover 12, the left cover 13 and the right cover 14 are integrally formed by metal materials. Since metal materials have a certain hardness, the mouse shell 10 made of metal materials can be made thinner to the greatest extent while ensuring the supporting force of the mouse shell 10, so as to achieve the lightweight of the mouse 100. The inner surface of the shell 10 is partially rough. The mouse 100 also includes a positioning structure 40. The positioning structure 40 can be used to connect the shell 10 and the base plate 20. The shell 10 and the base plate 20 are connected and fixed by the positioning structure 40. The positioning structure 40 is formed on the rough surface 17 by injection molding. It can be understood that the shell 10 is made of metal material and the positioning structure 40 is made of plastic material. The rough surface 17 is formed on the inner surface of the shell 10 to roughen the smooth inner surface of the shell 10 to facilitate the positioning structure 40 to be injection molded on the rough surface 17. Since the positioning structure 40 is difficult to be made thin and light, the positioning structure 40 made of plastic material is not only lighter than the positioning structure 40 made of metal material, but also has a higher degree of manufacturing precision. It also has a certain degree of elasticity, which is more convenient for connecting the shell 10 with the base plate 20.

[0031] The above structure is adopted, the shell 10 is formed by casting with metal material, and the high hardness of the metal material is used to create a thin mouse shell 10, so as to achieve the lightweight of the mouse 100. The smooth inner surface of the shell 10 is roughened by forming a rough surface 17 on the inner surface of the metal shell 10, so that the positioning structure 40 can be directly molded on the inner surface of the metal shell 10 by injection molding. The positioning structure 40 made of plastic material can improve the connection accuracy between the mouse shell 10 and the bottom plate 20. Compared with the prior art, the mouse 100 of the present application greatly reduces the uncertainty and high scrap rate of manual processing in the production process. Even if an injection molding fails, the process can be repeated without the entire mouse shell 10 being scrapped. In addition, the form of the injection-molded positioning structure 40 can be set according to the internal structure of the mouse 100, and the form is diverse, which is suitable for a variety of mouse 100 structures.

[0032] In one embodiment, see Fig.11 The rough surface 17 is formed on the inner surface of the shell 10 by laser or corrosion. The metal surface is roughened by laser impact or chemical corrosion process to form the rough surface 17, which can improve the bonding force between metal and plastic, so that the complex positioning structure 40 can be directly injection molded on the inner surface of the mouse 100 shell and is not easy to fall off, which facilitates the connection between the shell 10 and the positioning structure 40 and improves the connection stability.

[0033] In one embodiment, see Figure 6 The positioning structure 40 is an integral part and is injection molded on the inner surface of the metal shell 10. In some other embodiments, please refer to Fig.10 The positioning structure 40 can be injection-molded in sections on the inner surface of the metal shell 10 .

[0034] In one embodiment, see Figure 1 , 3 And 6, the mouse 100 includes a left button 51, a right button 52, a scroll wheel 53 and a button mounting structure 54, the button mounting structure 54 is used to mount the left and right buttons 52 and the scroll wheel 53, the button mounting structure 54 is formed by extending the positioning structure 40, and the button mounting structure 54 is formed by directly extending the positioning structure 40 in an integrated manner, which can simplify the product structure and facilitate production.

[0035] In one embodiment, see Figure 1 , 36, the upper cover 11 of the shell 10 is provided with an opening 15, and the opening 15 can accommodate the left and right buttons 52 and the roller 53, the button mounting structure 54 includes a left button mounting portion 541, a right button mounting portion 542 and a roller mounting hole 543, the roller mounting hole 543 is located between the left button mounting portion 541 and the right button mounting portion 542, the left button 51, the right button 52 and the roller 53 are respectively installed in the left button mounting portion 541, the right button mounting portion 542 and the roller mounting hole 543 of the button mounting structure 54, and the button mounting structure 54 is provided to facilitate the installation of the left and right buttons 52 and the roller 53.

[0036] Further, in one embodiment, see Figure 2 , 3 , 6 and 8, the positioning structure 40 is distributed in the upper cover 11, the front cover 12, the left cover 13 and the right cover 14, the opening 15 of the upper cover 11 extends to the edge of the front cover 12, and the key mounting structure 54 extends from the positioning structure 40 located in the upper cover 11 toward the opening 15 and is connected to the positioning structure 40 located in the front cover 12. It can be understood that in this scheme, the four end faces of the opening 15: one end face is located at the edge of the front cover 12, and the other three end faces are all located on the upper cover 11. At this time, the key mounting structure 54 is mainly extended from the positioning structure 40 in the upper cover 11, which has better support for the keys.

[0037] Further, in another embodiment, see Figure 2 , 3 , 6 and 9, the positioning structure 40 is distributed on the upper cover 11, the front cover 12, the left cover 13 and the right cover 14, the opening 15 of the upper cover 11 extends to the edges of the front cover 12, the left cover 13 and the right cover 14 respectively, the key mounting structure 54 extends from the positioning structure 40 located on the upper cover 11 toward the opening 15 and is connected to the positioning structure 40 located on the front cover 12, the left cover 13 and the right cover 14. It can be understood that in this scheme, the four end faces of the opening 15 are respectively located on the edges of the upper cover 11, the front cover 12, the left cover 13 and the right cover 14, that is, the size of the opening 15 is larger, and the exposed key mounting structure 54 is also larger. The key mounting structure 54 occupies the entire front end of the upper cover 11, is suitable for larger keys, and has better elasticity.

[0038] In one embodiment, see Figure 2 , 45, the mouse 100 includes two micro switches 55 and two pressing components 56, one button corresponds to one pressing component 56 and one micro switch 55, the two micro switches 55 are electrically connected to the circuit board 30, and the two pressing components 56 are used to trigger the corresponding micro switches 55 when the left and right buttons 52 are pressed. In other words, by pressing the left button 51 or the right button 52, the corresponding pressing component 56 can be driven to trigger the corresponding micro switch 55 to achieve the triggering function.

[0039] For further information, see Figure 2 and Figure 7 , the two pressing components 56 each include an elastic plate 561 and a pressing plate 562 mounted on the elastic plate 561, one end of the elastic plate 561 is connected to the positioning structure 40 located on the upper cover 11, and the other end of the elastic plate 561 is mounted on the button mounting structure 54, and the pressing plate 562 triggers the corresponding micro switch 55 when the button is pressed. In other words, when the left button 51 or the right button 52 is pressed, the corresponding pressing plate 562 can be driven to trigger the corresponding micro switch 55 to achieve the triggering function. It is precisely because the present application adopts the injection molding method that the positioning structure 40 in the upper cover 11 can meet diverse needs, so that one end of the elastic plate 561 can be directly mounted on the positioning structure 40, and the other end can achieve the triggering function through relative displacement or deformation.

[0040] For further information, see Figure 4 and Figure 5 The two micro switches 55 each include a contact 551, and a top block 563 is provided at the position corresponding to the contact 551 on each pressing plate 562. When the left and right buttons 52 are pressed, the pressing plate 562 can push the corresponding top block 563 to move downward and drive the contact 551. The contact 551 is pushed by the top block 563, which makes the operation simpler.

[0041] In one embodiment, see Figure 4 and Figure 5, a groove 564 may be provided at the side end of the top block 563, and an insert block 544 may be provided in the key installation structure 54, and the insert block 544 is inserted into the groove 564. When the key is pressed, the pressing block pushes the top block 563 to move downward, and the insert block 544 moves upward relative to the groove 564. When the insert block 544 abuts against the upper side wall of the groove 564, the top block 563 cannot move further downward. On the contrary, when the key is released, the top block 563 rebounds, and the slot moves downward relative to the groove 564. When the insert block 544 abuts against the lower side wall of the groove 564, the top block 563 cannot move further upward. In other words, the pressing stroke of the top block 563 is limited by the cooperation of the insert block 544 and the groove 564, so as to prevent the top block 563 from excessively contacting the contact 551, which may cause the micro switch 55 to be easily damaged. It can be understood that a through hole may also be provided at the side end of the top block 563, and the through hole and the groove 564 may play the same role.

[0042] In one embodiment, see Figure 4 and Figure 5 The mouse 100 further includes a side key circuit board 57, the left side cover 13 is provided with at least one side key hole 16, the positioning structure 40 and the button mounting structure 54 located on the upper cover 11 respectively extend at least one positioning column 41 downward, and the side key circuit board 57 is installed on the positioning column 41. It can be understood that the mouse 100 is also provided with a side key 58, and the side key 58 is electrically connected to the side key circuit board 57. The positioning structure 40 of the upper cover 11 extends at least one positioning column 41 downward, and the button mounting structure 54 extends at least one positioning column 41 downward. The installation of the side key circuit board 57 on these positioning columns 41 can make the internal structure of the mouse 100 more compact and miniaturize the mouse 100. Of course, in order to make the side key circuit board 57 more stable, the side key circuit board 57 can be installed on these positioning columns 41 and the left side cover 13.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
