Description

Technical Field

[0001] The utility model relates to the field of computer accessories, in particular to a mouse. Background Art

[0002] As a crucial computer input device, the mouse's structural design directly impacts production efficiency and cost. The basic structure of a traditional mouse typically consists of core components, including an upper shell, a lower shell, and a circuit board. There are two typical structures for connecting the upper and lower shells.

[0003] The first structure uses a pure screw locking and fixing method. Specifically, during the assembly process, multiple screws need to be installed and tightened from the bottom surface of the bottom shell to fix the upper and lower shells. The second structure uses a composite fixing method that combines hooks and screw locking. This design configures a hook structure at the front end of the upper shell and the lower shell, and uses screws to lock the rear end. A specific operating sequence needs to be followed during assembly: first, the front end of the upper shell must be hooked and docked with the front end of the lower shell at a specific angle from front to back to ensure that the front hook is securely engaged; then, the bottom of the lower shell is locked and fixed to the upper shell with screws.

[0004] Both designs face the common challenge of achieving automated production due to their complex assembly processes. For example, the assembly of the hook requires specific angles and orientations. These complex assembly requirements make it difficult or expensive to completely replace manual labor with automated equipment, resulting in continued reliance on manual labor. This results in low production efficiency, making it unable to meet the demands of modern large-scale production. Furthermore, high labor costs contribute to high product costs. Utility Model Content

[0064] The mouse according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0065] Reference Figures 1 to 6 As shown, a mouse according to an embodiment of the present invention includes a bottom shell 10, a middle shell 20, an upper shell 30, and a circuit board. Multiple positioning posts 101 and multiple first latches 102a and 102b are provided within the bottom shell 10. The multiple positioning posts 101 are spaced along the periphery of the bottom shell 10, ensuring multi-point positioning during assembly and ensuring accurate and reliable positioning. The multiple first latches 102a and 102b are dispersed within the bottom shell 10. This dispersed arrangement ensures uniform securing force and improves the stability of the overall structure.

[0066] The middle shell 20 is located above the bottom shell 10. The middle shell is provided with a plurality of positioning holes and a plurality of second fasteners 201a and 201b. The plurality of positioning holes corresponds one-to-one to the plurality of positioning posts 101. Each positioning post 101 is positioned and matched with the corresponding positioning hole. In this way, the middle shell 20 and the bottom shell 10 can be accurately positioned and fixed by the corresponding matching of the plurality of positioning posts 101 and the plurality of positioning holes.

[0067] It is understandable that in other embodiments, multiple positioning posts can be provided on the middle shell 20, and multiple positioning holes can be provided on the bottom shell 10. In this way, the positioning posts on the middle shell 20 cooperate with the positioning holes on the bottom shell 10 to achieve the same positioning and fixing effect.

[0068] The plurality of second latches 201a, 201b correspond one-to-one with the plurality of first latches 102a, 102b. Each second latch 201a, 201b engages with the corresponding first latch 102a, 102b to secure the middle shell 20 to the bottom shell 10 and define a receiving space. After the middle shell 20 and the bottom shell 10 are precisely positioned using the positioning posts 101 and positioning holes, the plurality of second latches 201a, 201b engage one-to-one with the plurality of first latches 102a, 102b to achieve assembly and securement between the middle shell 20 and the bottom shell 10.

[0069] The upper shell 30 is disposed on the middle shell 20, and the front end of the upper shell 30 has a left pressing piece 301 and a right pressing piece 302. Preferably, the left pressing piece 301, the right pressing piece 302 and the upper shell 30 form an integral structure. A circuit board is disposed within the accommodating space, and the circuit board has a left button and a right button. The left button is located below the left pressing piece 301 and can be pressed and triggered by the left pressing piece 301. The right button is located below the right pressing piece 302 and can be pressed and triggered by the right pressing piece 302. The left and right button functions of the mouse can be realized by the left pressing piece 301 and the right pressing piece 302 on the upper shell 30 and the left and right buttons on the circuit board.

[0070] At least one of the corresponding first latches 102a, 102b and second latches 201a, 201b is provided with an inclined guide surface for guiding the first latches 102a, 102b and second latches 201a, 201b to engage with each other when the middle shell 20 and the bottom shell 10 are assembled in the up-down direction. In this embodiment, an inclined guide surface is provided on at least one of the first latches 102a, 102b and the second latches 201a, 201b. The design of such an inclined guide surface is based on the consideration of assembly convenience. Its function is to provide guidance for the mutual engagement of the first latches 102a, 102b and the second latches 201a, 201b when the middle shell 20 and the bottom shell 10 are assembled in the up-down direction, thereby reducing the difficulty of assembly, realizing a single up-down assembly, facilitating automated production, and improving assembly efficiency.

[0071] According to the mouse provided in the embodiment of the present invention, the bottom shell 10 and the middle shell 20 are secured together by the cooperation of the positioning posts 101 with the positioning holes, and the interlocking of the first latches 102a, 102b with the second latches 201a, 201b. The inclined guide surfaces provided on the first latches 102a, 102b and / or the second latches 201a, 201b provide guidance during assembly, significantly simplifying the assembly process. This design completely eliminates the traditional screw fastening method and the specific front-to-back assembly orientation required in a combined hook and screw fastening structure, allowing the middle shell 20 to be directly assembled with the bottom shell 10 in a vertical direction. The corresponding arrangement of multiple positioning posts 101 and positioning holes ensures accurate positioning during assembly, while the dispersed arrangement of the latches provides reliable fixing force. This not only greatly reduces the assembly difficulty but also makes the entire assembly process more intuitive and standardized, making it particularly suitable for automated production line operations, effectively improving production efficiency and reducing labor costs. At the same time, this structure still ensures product stability and reliability.

[0072] Reference Figure 3 and Figures 5 and 6 As shown, in some embodiments of the present invention, at least two 102a of the plurality of first fasteners 102a, 102b are arranged at the front end of the bottom shell 10, and at least one 102b of the plurality of first fasteners 102a is arranged at the rear end of the bottom shell 10.

[0073] In this embodiment, at least two first latches 102a are provided in the front region of the bottom shell 10. This multi-point arrangement provides a more reliable securing force, effectively preventing the structure from loosening during repeated pressing operations. Furthermore, the provision of multiple first latches 102a can disperse stress, avoiding structural damage that may result from localized stress concentration. At least one first latch 102b is provided in the rear region of the bottom shell 10. When one first latch 102b is provided in the rear region of the bottom shell 10, the front and rear first latches 102a and 102b form a triangular arrangement, providing a good securing effect.

[0074] By distributing the clips with more at the front and fewer at the back, the front-end multi-point fixation provides stable support, ensuring accurate and reliable key operation. Furthermore, the clips at the back provide positioning and restraint, ensuring the reliability of the assembly structure. This distribution also facilitates assembly and disassembly of the housing for maintenance.

[0075] Reference Figure 2 、 Figure 3 and Figures 5 and 6 As shown, in one embodiment of the present invention, the first fasteners 102a, 102b include an arm 1021 and a buckle 1022 located at the upper end of the arm 1021, the buckle 1022 of the first fastener 102a at the front end of the bottom shell 10 protrudes in a first direction, and the buckle 1022 of the first fastener 102b at the rear end of the bottom shell 10 protrudes in a second direction, and the first direction and the second direction are opposite.

[0076] In this embodiment, the first latching members 102a and 102b utilize an arm 1021 and a buckle 1022. The arm 1021 provides the necessary elastic deformation space, allowing the first latching members 102a and 102b to have a certain deformation margin, facilitating the snap-fit ​​operation during assembly. The buckle 1022 is disposed at the upper end of the arm 1021 and is a structure that implements the snap-fit ​​function. In the first latching member 102a at the front end of the bottom shell 10, the buckle 1022 is designed to protrude in a first direction, while the buckle 1022 of the first latching member 102b at the rear end of the bottom shell 10 protrudes in a second direction opposite the front end. For example, the buckle 1022 of the first latching member 102a at the front end of the bottom shell 10 protrudes forward, while the buckle 1022 of the first latching member 102b at the rear end of the bottom shell 10 protrudes backward. This design in opposite directions makes the buckle restraint more reliable, improves the connection strength between the middle shell 20 and the bottom shell 10, and also facilitates disassembly and maintenance. When assembling, pressing the middle shell 20 downward can cause the first buckle members 102a and 102b at the front and rear ends of the bottom shell 10 to deform in a direction close to each other, finally achieving engagement.

[0077] Reference Figure 3 、 Figures 5 and 6 As shown, in one embodiment of the present invention, an upwardly protruding storage seat 103 is provided in the bottom shell 10, and the bottom surface of the bottom shell is provided with a socket H101 for inserting and accommodating the wireless receiver 11 in the storage seat 103; the storage seat 103 is located at the rear end of the bottom shell 10, and at least one of the first fasteners 102b is provided on the storage seat 103.

[0078] In other words, the storage seat 103 protrudes upward from the inner wall of the bottom shell 10, and a separate storage slot is formed in the storage seat 103. The shape and size of this storage slot match the wireless receiver 11. A socket H101 is provided on the bottom surface of the bottom shell, which is connected to the storage seat 103. The wireless receiver 11 can be inserted into the storage slot through the socket H101, making it convenient for the user to store the wireless receiver 11 in the mouse and access it when needed.

[0079] Furthermore, in this embodiment, a first latch 102b is provided on the storage seat 103. This structural design of combining the first latch 102b with the storage seat 103 fully utilizes the three-dimensional space of the storage seat 103 and saves overall structural space. Since the storage seat 103 itself has a certain structural strength, disposing the first latch 102b thereon can provide more reliable support.

[0080] Reference Figures 5 and 6 As shown, in one embodiment of the present invention, the socket H101 passes through the storage seat 103 in the up and down directions, at least part of the side wall of the storage seat 103 serves as the arm 1021 of the first latch 102b, and the latch 1022 protrudes toward the outside of the storage seat 103.

[0081] In this embodiment, a portion of the sidewall of the storage seat 103 is directly used as the arm portion 1021 of the first latch 102b. This design achieves a high degree of structural integration. Furthermore, when the wireless receiver 11 is inserted into the storage seat 103, because the size and shape of the wireless receiver 11 are similar to those of the storage seat 103, the wireless receiver 11 blocks the sidewall of the storage seat 103 from deforming inward, thereby preventing the first latch 102b from disengaging, improving the reliability of the engagement, and thereby enhancing the drop resistance and other performance. Furthermore, the through-type design of the socket H101 makes it easier for the sidewall of the storage seat 103 to deform inward. During the assembly process of the bottom shell 10 and the middle shell 20, the wireless receiver 11 has not yet been inserted into the storage seat 103. At this time, the sidewall of the storage seat 103 is easily deformed inward, thereby ensuring easier assembly and disassembly.

[0082] The side wall of the storage seat 103 and the first snap-fit ​​component 102b are integrated into the structure, so that the storage seat 103 not only has the function of storing and protecting the wireless receiver 11, but also has the elastic deformation ability required by the arm 1021. While meeting the convenience of assembly and disassembly, it also ensures that the snap-fit ​​structure is more reliable, improves the structural strength and anti-fall performance.

[0083] Reference Figure 6 As shown, in one embodiment of the present invention, the side wall of the storage seat 103 is provided with at least two cutouts H103 extending in the up-down direction, and the side wall portion between the two cutouts H103 serves as the arm portion 1021 of the first latch 102b.

[0084] In other words, the two cutouts H103 can be used to separate an independent sidewall area from the sidewall of the storage seat 103, and this sidewall area serves as the arm 1021 of the first latch 102b. This design allows the sidewall area to produce relatively independent inward elastic deformation while maintaining the necessary support strength, thereby providing the latch structure with good elastic deformation capabilities without affecting the stability of the overall structure, thus making the assembly process easier and smoother. At the same time, since the setting of the cutout H103 only affects the deformation characteristics of the local area, it will basically not weaken the overall structural strength of the storage seat 103. Therefore, while providing convenient assembly characteristics, it still maintains the effective protection of the storage seat 103 for the wireless receiver 11. In addition, when the wireless receiver 11 is inserted into the storage seat 103, it will provide additional support to the arm 1021 to prevent disengagement, further enhancing the stability and reliability of the latch structure.

[0085] Reference Figures 5 and 6 As shown, in one embodiment of the present invention, the upper end of the arm portion 1021 of the first latch 102b has an ear portion 1023 protruding toward the inner side of the receiving seat 103, and the ear portion 1023 is provided with a through hole H102.

[0086] By providing an ear portion 1023 with a through hole H102 on the arm portion 1021, a force point is provided during the disassembly process, making the disassembly operation more controllable and convenient. When the middle shell 20 needs to be disassembled, the wireless receiver 11 is first removed from the storage seat 103. Then, an appropriate tool (such as a screwdriver) is inserted from the storage seat 103 and inserted through the through hole H102 of the ear portion 1023. The tool is used to apply force to move the ear portion 1023 toward the inside of the storage seat 103. At this time, the ear portion 1023 causes the arm portion 1021 to deform inward, thereby disengaging the buckle portion 1022 from the second latching members 201a and 201b on the middle shell 20, thereby separating the middle shell 20 from the bottom shell 10. This design not only simplifies the disassembly process, but also reduces the difficulty of operation, effectively avoiding the structural damage that may be caused by forced disassembly. Furthermore, the ear portion 1023 and its through hole H102 are concealed within the storage base 103, which does not affect the appearance and normal use of the product and prevents accidental disassembly. The ear portion 1023 can only be accessed after removing the wireless receiver 11 for maintenance. This design ensures both safe use and convenient maintenance.

[0087] Reference Figures 2 to 4 As shown, in some embodiments of the present invention, the top surface of the middle shell 20 is provided with a groove that is compatible with the upper shell 30, and the upper shell 30 is located in the groove and is snap-connected to the middle shell 20. The shape, size and depth of the groove match those of the upper shell 30. The upper shell 30 is accommodated in the groove during installation and forms a reliable fixed connection with the middle shell 20 through a snap-fit ​​structure. This groove design not only ensures the accurate positioning of the upper shell 30, but also because the upper shell 30 is embedded in the groove, the transition between the upper shell 30 and the middle shell 20 is more natural and smooth, without producing obvious step differences, thereby improving the appearance and texture of the product. In addition, the snap-fit ​​connection method not only ensures the firmness of the structure, but also facilitates assembly and disassembly and maintenance when necessary.

[0088] Reference Figure 3 and Figure 4 As shown, in one embodiment of the present invention, a first touch-pressing portion 3011 protruding downward is provided at the bottom of the left pressing plate 301, and a first sliding hole H301 is provided on the rear side of the first touch-pressing portion 3011; a second touch-pressing portion 3021 protruding downward is provided at the bottom of the right pressing plate 302, and a second sliding hole H302 is provided on the rear side of the second touch-pressing portion 3021.

[0089] The middle shell 20 is provided with a first stopper 203 and a second stopper 204 protruding forward. The first stopper 203 is inserted into the first sliding hole H301 and can slide relative to it up and down. The second stopper 204 is inserted into the second sliding hole H302 and can slide relative to it up and down. This ensures that the left and right pressing plates 301 and 302 have an appropriate pressing stroke.

[0090] In this embodiment, the sliding engagement between the first sliding hole H301 and the first stopper 203, and the second sliding hole H302 and the second stopper 204, effectively constrains the movement direction of the left and right pressing plates 301 and 302, ensuring that the pressing motion remains strictly vertical. This avoids potential tilting and offsetting during the pressing process, improving the precision and quality of key operation. Furthermore, the depth of the first and second sliding holes H301 and H302 precisely controls the travel of the left and right pressing plates 301 and 302, providing the user with a perfectly balanced pressing feel. Furthermore, the sliding engagement between the first sliding hole H301 and the first stopper 203, and the second sliding hole H302 and the second stopper 204, provides vertical positioning. This positioning, combined with the snap-fit ​​connection design of the upper shell 30, ensures the reliability of the upper shell 30 and the middle shell 20 after assembly, ensuring that the upper shell 30 does not easily fall off the middle shell 20.
