[0063] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0064] In the related art, the weight of the mouse is reduced by setting hollows on the mouse shell. Specifically, the shell is provided with multiple hollows arranged at intervals, but the opening area of ​​a single hollow is small and a certain distance is maintained between each hollow. Setting multiple hollows can remove more weight of the mouse, and keeping a certain distance between each hollow can ensure the support effect of the mouse shell and prevent the shell from deforming during the use of the mouse. Although the setting of these hollows reduces the weight of the mouse to a certain extent, the existence of the hollows will allow foreign matter to enter the inside of the mouse. If the foreign matter entering the inside of the mouse is attached to the sensor or control motherboard inside the mouse, it will cause the mouse to move unsmoothly and respond insensitively during use, and even cause the mouse to malfunction and cannot be used normally. In particular, when the foreign matter entering the inside of the mouse is conductive, it is likely to cause a short circuit in the circuit inside the mouse, thereby damaging the mouse. In order to prevent foreign matter from entering the inside of the mouse, in the related art, a protective plate can be set on the outside of the mouse, but the setting of the protective plate will increase the weight of the mouse on the one hand, and on the other hand, the waterproof effect still does not meet the requirements.

[0065] For this reason, please see Figures 1 to 10 The utility model provides a shell assembly 100, which can be used for a mouse 10. It should be noted that the mouse 10 includes a middle button scroll wheel 200 and a control motherboard 300. The middle button scroll wheel 200 is a scrollable component located between the left button and the right button on the mouse 10, which can have the basic function of turning pages (scrolling pages). The control motherboard 300 can control various functions of the mouse 10. It can receive signals from components such as the left button, right button, middle button scroll wheel 200 and sensors of the mouse 10, and quickly process these signals, and transmit the processing results to the computer, thereby realizing various operations of the mouse 10.

[0066] See also Figure 1-Figure 3The housing assembly 100 includes a housing, a first protective plate 130 and a bottom plate 120. The housing includes a front housing 111 and a rear housing 112. It should be noted that the distinction between the "front housing 111" and the "rear housing 112" is as follows: based on the middle button roller 200, the part away from the middle button roller 200 is the rear housing 112, and the part close to and installed with the middle button roller 200 is the front housing 111. The front housing 111 is provided with a first avoidance hole 1111 for avoiding the middle button roller 200. The rear housing 112 is provided with a first through hole 1125, and the setting of the first through hole 1125 effectively reduces the weight of the mouse 10. The first protective plate 130 is connected to the rear housing 112 and can cover the first through hole 1125 to prevent foreign matter (such as dust, water stains, etc.) from entering the mouse 10 through the first through hole 1125 and affecting the electronic components in the mouse, thereby affecting the normal use of the mouse 10. In one embodiment, the front shell 111 and the rear shell 112 are integrally formed. Specifically, the shell can be formed by injection molding or thermoforming (first, the material is heated to a plastic state by heat energy, and then formed by a mold). The shell can also be manufactured by extrusion molding or by machining. Among them, the front shell 111 can protect the middle button roller 200 and the left and right buttons, and the rear shell 112 can define a storage space for the control motherboard 300, the battery 400 and other components inside the mouse 10, and provide support for the hand to prevent the mouse 10 from deforming during use. In one embodiment, the rear shell 112 exists in the form of a frame structure, so that the weight of the shell can be greatly reduced. The first protective plate 130 is connected to the rear shell 112 and can cover the first perforation 1125. Therefore, when the mouse 10 is in use, the pressure applied by the user's hand at the first protective plate 130 can be transmitted to the rear shell 112 through the first protective plate 130. Therefore, the first protective plate 130 can provide effective support for the user's hand.

[0067] See also Figure 2-Figure 5, the bottom plate 120 can be connected to the outer shell, and the bottom plate 120 and the outer shell together define a cavity 160 suitable for accommodating the control mainboard 300. The rear shell 112 includes a first protrusion 1121 protruding into the first through hole 1125, and the first protrusion 1121 is provided with a first connecting structure 1123. The bottom plate 120 is provided with a second connecting structure 123, and the first connecting structure 1123 can be connected to the second connecting structure 123, so that the outer shell is connected to the bottom plate 120. The number of the first connecting structure 1123 and the second connecting structure 123 can be one or more. When the number of the first connecting structure 1123 and the second connecting structure 123 is multiple, each first connecting structure 1123 is connected to each second connecting structure 123 in a one-to-one correspondence. In this embodiment, the number of the first connecting structure 1123 and the second connecting structure 123 is two. Specifically, the first protrusion 1121 can be protruded from the opening edge of the first through-hole 1125, and the first connecting structure 1123 can be a threaded hole 11232, or other structures that can be snapped. Multiple second connecting structures 123 can be arranged around the edge of the bottom plate 120. In one embodiment, when the first connecting structure 1123 is a threaded hole 11232, the second connecting structure 123 can also be a threaded hole 11232, and the connection between the bottom plate 120 and the shell is achieved by a threaded fastener, that is, the threaded fastener is sequentially passed through the second connecting structure 123 and the first connecting structure 1123 and tightened, so that the bottom plate 120 can be fixed to the rear shell 112. In another embodiment, the connection method between the bottom plate 120 and the shell can also be snap-fitting. Specifically, if the first connecting structure 1123 is set as a snap-in groove, the second connecting structure 123 is configured as a snap-in tooth, and the snap-in tooth can be snapped into the snap-in groove, so that the base plate 120 can be fixed to the shell and together with the shell define a cavity 160. The control main board 300, sensor and other components inside the mouse 10 can be accommodated in the cavity 160, and the shell and the first protective plate 130 can protect these components to prevent foreign matter from interfering with the normal operation of the control main board 300 and other components.

[0068] To improve the connection stability between the bottom plate 120 and the housing, in one embodiment, refer to Figure 3 and Figure 6The first connection structure 1123 includes a first fixing column 11231, and the second connection structure 123 includes a second fixing column 1231 abutting against the first fixing column 11231; the first fixing column 11231 is provided with a threaded hole 11232, and the second fixing column 1231 is provided with a first through hole 1232 communicating with the threaded hole 11232. The housing assembly 100 also includes a threaded connector, which passes through the first through hole 1232 and is threadedly connected with the threaded hole 11232, so that the bottom plate 120 is fixed to the housing. Compared with the connection mode of the first connection structure 1123 and the second connection structure 123 being connected by clamping, the connection between the first connection structure 1123 and the second connection structure 123 is more stable when the first connection structure 1123 and the second connection structure 123 are threadedly connected.

[0069] In one embodiment, see Figure 7 and Figure 8 , the rear shell 112 also includes a second protrusion 1122 protruding into the first through-hole 1125, and a reinforcing rib 1124 is provided on the side of the second protrusion 1122 facing the bottom plate 120. After the bottom plate 120 is installed in the outer shell, the reinforcing rib 1124 can abut against the bottom plate 120. The abutment between the reinforcing rib 1124 and the bottom plate 120 can significantly enhance the overall structural stability of the mouse 10. It helps to prevent the outer shell from being deformed or damaged when subjected to external forces, and the provision of the reinforcing rib 1124 can improve the durability and service life of the mouse 10. On the other hand, when the mouse 10 is clicked or moved, the reinforcing rib 1124 can absorb the impact force generated during the clicking or moving of the mouse 10, thereby reducing the vibration amplitude of the bottom plate 120 relative to the outer shell, which helps to reduce the vibration and noise generated by the mouse 10 during use. To reduce the use of threaded connectors, in one embodiment, refer to Figure 4 , Figure 5 and Figure 8 , a groove 11241 is provided on the side of the reinforcing rib plate 1124 facing the bottom plate 120, and the bottom plate 120 includes a strip flange 122 extending toward the shell, and the upper end of the strip flange 122 can extend into the groove 11241, so that the bottom plate 120 can be fixed to the shell. Since the bottom plate 120 is directly connected to the shell through the groove 11241, the number of threaded connectors used is reduced, and in order to effectively reduce the weight of the mouse 10, the shell, bottom plate 120 and other structures can be made of non-metallic materials. When threaded connection is adopted, in order to ensure the stability of the connection, the threaded connector is made of metal parts, which is heavier than non-metallic materials of the same volume. Therefore, connecting the bottom plate 120 to the shell through the groove 11241 can further reduce the weight of the mouse 10. When the shell is provided with a plurality of reinforcing ribs and each reinforcing rib is provided with a groove 11241 , in some embodiments, the strip flange 122 may be arc-shaped, and the arc-shaped strip flange 122 simultaneously extends into the grooves 11241 of all the reinforcing ribs, so that the bottom plate 120 can be fixed to the shell.

[0070] In order to increase the aesthetics of the mouse 10, in one embodiment, refer to Fig.10 The first protective plate 130 includes a transparent layer 131 and a pattern layer 132. The transparent layer 131 can be attached to the pattern layer 132, so as to protect the pattern layer 132 and prevent the pattern layer 132 from being worn and affecting the aesthetics of the mouse 10. A pattern is provided on one side of the pattern layer 132 attached to the transparent layer 131, and the pattern layer 132 can cover the first perforation 1125.

[0071] See also Figure 7 and Fig. 9 In order to ensure the stability of the structure of the mouse 10, the rear shell 112 also includes an intermediate beam 1126, which is located in the first through hole 1125, and one end of the intermediate beam is connected to the hole wall at the front end of the first through hole 1125, and the other end is connected to the hole wall at the rear end of the first through hole 1125. The intermediate beam 1126 can provide support for the first protective plate 130 while strengthening the structural strength of the rear shell 112, so as to prevent the first protective plate 130 from being impacted by external forces or being sunken after long-term use, thereby affecting the feel of the mouse 10 and the aesthetics of the mouse 10. It should be noted that the intermediate beam 1126 is configured as an arched structure protruding toward the outside of the first through hole 1125, and the arched structure fits the hand line to improve the comfort of the mouse 10. At the same time, the arched structure can also support the first protective plate 130 more effectively. In order to reduce the weight of the mouse 10 and improve the integrity of the shell, the intermediate beam 1126 and the rear shell 112 can be integrally injection molded.

[0072] In order to avoid the mouse 10 being limited by the length of the cable during use, the mouse 10 is provided with a battery 400, which can be a replaceable battery 400 or a rechargeable battery 400. Figure 2 , Figure 4 and Figure 6 In one embodiment, the battery 400 is disposed in the cavity 160. The middle beam 1126 is provided with an abutment portion 1127, which is disposed on the side of the middle beam 1126 facing the battery 400. The abutment portion 1127 can abut the battery 400, thereby limiting and fixing the battery 400, and preventing the battery 400 from shaking in the cavity 160 during use or transportation of the mouse 10, thereby affecting or even damaging other components inside the mouse 10.

[0073] The first protection plate 130 includes a transparent layer 131 and a pattern layer 132. The transparent layer 131 can be attached to the pattern layer 132. A pattern is provided on the side of the pattern layer 132 attached to the transparent layer 131, and the pattern layer 132 can cover the first perforation 1125. In one embodiment, the pattern layer 132 is collaged from a plurality of graphic elements, and each graphic element avoids the first protrusion 1121, the second protrusion 1122, and the middle beam 1126 and is attached to the transparent layer 131. In one embodiment, a pattern can be provided on the side of the first protrusion 1121 away from the cavity 160, a pattern can be provided on the side of the second protrusion 1122 away from the cavity 160, and a pattern can also be provided on the side of the middle beam 1126 away from the cavity 160. The patterns provided on the first protrusion 1121, the second protrusion 1122, and the middle beam 1126 and the patterns of each graphic element together form a complete pattern. In another embodiment, the pattern layer 132 is provided with an avoidance groove, the position of which corresponds to the projection position of the first protrusion 1121 on the pattern layer 132, the projection position of the second protrusion 1122 on the pattern layer 132, and the projection position of the middle beam 1126 on the pattern layer 132. The provision of the avoidance groove makes the thickness of the pattern layer 132 at the first protrusion 1121, the second protrusion 1122, and the middle beam 1126 thinner, and the weight of the pattern layer 132 is lower. In addition, the provision of the avoidance groove is also conducive to the positioning of the first protective plate 130 when it is installed on the rear shell 112.

[0074] It should be noted that the transparent layer 131 can be connected to the first protrusion 1121, the second protrusion 1122 and the middle beam 1126, and the first protrusion 1121, the second protrusion 1122 and the middle beam 1126 can provide good support for the transparent layer 131, thereby improving the installation stability of the transparent layer 131. The transparent layer 131 and the housing can be connected by gluing, and the pattern layer 132 and the transparent layer 131 can also be connected by gluing, thereby avoiding the use of other additional connection structures, and further reducing the weight of the mouse 10.

[0075] In order to further reduce the weight of the mouse 10 while ensuring the structural stability of the mouse 10, the wall thickness of the shell and the bottom plate 120 can be 1mm to 1.4mm. For example, the wall thickness of the shell can be 1.1mm, 1.15mm, 1.2mm, 1.25mm, 1.3mm, 1.35mm, etc. The wall thickness of the bottom plate 120 can be 1.1mm, 1.2mm, 1.3mm, 1.37mm, etc. The wall thickness of the shell can be the same as or different from the wall thickness of the bottom plate 120. The material used for the shell and the bottom plate 120 can be aluminum alloy, magnesium alloy, carbon fiber composite material, or high molecular polymer. The thickness of the first protective plate 130 can be designed to be 0.4mm. In one embodiment, the thickness of the transparent layer 131 can be equal to the thickness of the pattern layer 132. In another embodiment, the thickness of the pattern layer 132 may not be equal to the thickness of the transparent layer 131. Among them, the thickness of the transparent layer 131 can be designed to be 0.17mm~0.19mm. Exemplarily, the thickness of the transparent layer 131 can be 0.18mm. The thickness of the pattern layer 132 can also be designed to be 0.17mm~0.19mm. Exemplarily, the thickness of the pattern layer 132 can be 0.18mm. The pattern of the pattern layer 132 can be drawn by printing or by electroplating. It should be noted that the sum of the thickness of the transparent layer 131 and the thickness of the pattern layer 132 should be equal to 0.4mm (within the error range, even if the sum of the thickness of the transparent layer 131 and the thickness of the pattern layer 132 is greater than 0.4mm or less than 0.4mm, it can also be considered to be equal to 0.4mm). The material used for the transparent layer 131 can be transparent PMMA (full name: polymethyl methacrylate), and the material used for the pattern layer 132 can be transparent PC (full name: polycarbonate).

[0076] See also Figure 4 The abutting portion 1127 includes an annular plate connected to the middle beam body 1126, and the annular plate has a first port 11271 and a second port 11272 that are arranged opposite to each other. The first port 11271 is close to the battery 400, while the second port 11272 is away from the battery 400, and the middle beam body 1126 is provided with a second through hole 11261 that is connected to the second port 11272. Specifically, the edge of the first port 11271 abuts the battery 400, and the abutting portion 1127 is configured as an annular plate, which is beneficial to the heat dissipation of the battery 400. In addition, compared with the abutting portion 1127 being configured as a solid structure, the abutting portion 1127 with an annular plate structure has a lower weight, thereby effectively reducing the weight of the mouse 10. In addition, a second through hole 11261 is provided at the connection between the middle beam body 1126 and the second port 11272 . The provision of the second through hole 11261 ensures the structural strength of the middle beam body 1126 while reducing the weight of the middle beam body 1126 , thereby reducing the weight of the mouse 10 .

[0078] In order to facilitate the clicking or pressing of the first pressing plate 170 and the second pressing plate 180 and improve the flexibility of the mouse 10, in one embodiment, the first pressing plate 170 has a first turning portion, one end of the first turning portion is connected to the front end of the first pressing plate 170, and the other end is connected to the rear end of the first pressing plate 170, and the first turning portion makes the rear end of the first pressing plate 170 protrude into the cavity 160 relative to the front end of the first pressing plate 170. The second pressing plate 180 has a second turning portion, one end of the second turning portion is connected to the front end of the second pressing plate 180, and the other end is connected to the rear end of the second pressing plate 180, and the second turning portion makes the rear end of the second pressing plate 180 protrude into the cavity 160 relative to the front end of the second pressing plate 180. Therefore, after the rear end of the first pressing plate 170 is fixed to the third connection structure 1128 through the second avoiding hole 1112, and the rear end of the second pressing plate 180 is fixed to the fourth connection structure 1129 through the third avoiding hole 1113, the user can press the front end of the first pressing plate 170 and the second pressing plate 180 with a small force, thereby avoiding hand discomfort after long-term use of the mouse 10, and effectively improving the comfort of the mouse 10. Specifically, the first pressing plate 170 and the second pressing plate 180 are configured as a "Z"-shaped structure.

[0079] In order to reduce the weight of the bottom plate 120, in one embodiment, the bottom plate 120 is configured as a hollow structure, and the control mainboard 300, the battery 400 and other components can be fixed through the hollow structure of the bottom plate 120. In another embodiment, the control mainboard 300, the battery 400 and other components can also be fixed to the shell in a hanging manner. In order to effectively utilize the space inside the mouse 10, some components inside the mouse 10 are fixed to the bottom plate 120, and other components are fixed to the shell. Specifically, the bottom plate 120 is provided with a plurality of second perforations 121, and adjacent second perforations 121 are separated by mounting rods, and some components inside the mouse 10 can be fixed by the mounting rods. The provision of a plurality of second perforations 121 effectively reduces the weight of the bottom plate 120.

[0080] See also Figure 2 and Figure 3 The housing assembly 100 further includes a second protective plate 140, which is attached to the side of the bottom plate 120 away from the shell, and the second protective plate 140 can cover each second perforation 121 to prevent foreign matter from entering the inside of the mouse 10 through the second perforation 121. Since the bottom plate 120 needs to provide support for the components inside the mouse 10 and the structure such as the shell, the bottom plate 120 is thicker and the performance requirements such as the structural strength of the bottom plate 120 are higher. The bottom plate 120 is provided with a plurality of second perforations 121, which can reduce the weight of the bottom plate 120 while meeting the support requirements for the internal components of the mouse 10. At this time, the second protective plate 140 only needs to provide protection, so the wall thickness of the second protective plate 140 can be much lower than the wall thickness of the bottom plate 120. Generally speaking, the weight of the bottom plate 120 is reduced. In addition, the second protective plate 140 can also be made of other materials that do not require high structural performance of the material, which can reduce material costs.

[0081] See also Figure 2 In one embodiment, the mouse 10 is provided with a display 500, which can display information such as the power level and charging status of the mouse 10, so that the user can timely know the status of the mouse 10 and adjust it in time. The setting of the display 500 improves the visibility of the functions of the mouse 10. For details, please refer to Fig. 9, the front shell 111 is provided with a fourth avoidance hole 1114, and the fourth avoidance hole 1114 is suitable for installing the display 500. The housing assembly 100 also includes a display cover plate 190150, which is connected to the side of the front shell 111 away from the cavity 160, and the display cover plate 190150 can cover the fourth avoidance hole 1114. In order to facilitate the observation of the information displayed on the display 500, the display cover plate 190150 is configured to be translucent. When the display 500 is on, the observer can observe the picture displayed by the display 500, and when the display 500 is off, the observer cannot see the existence of the display 500. The setting of the display cover plate 190150 allows the display 500 to be protected, and at the same time, because the display cover plate 190150 is configured to be translucent, the aesthetics of the mouse 10 is improved.
