Description

Technical Field

[0001] This application relates to the field of mouse technology, and in particular to a mouse with interchangeable appearance. Background Technology

[0002] The mouse is an important input device for computers. Its core function is to translate the user's physical actions into computer commands through intuitive physical movement and button operation. It is one of the most important interactive tools in the graphical era.

[0003] In related technologies, most mice on the market currently have a fixed shell design, and users cannot change the appearance of the mouse according to personal preferences or usage scenarios. As consumers' demand for personalized products increases, the uniform appearance of traditional mice can no longer meet user needs.

[0004] Existing mice suffer from the following problems: their fixed shell design restricts users' freedom to change the appearance according to personal aesthetics or usage scenarios, failing to meet the trend of diversification of a single device and seriously affecting the user experience. Utility Model Content

[0005] To improve the user experience, this application provides a mouse with interchangeable appearance.

[0006] The mouse with interchangeable appearance provided in this application adopts the following technical solution: A mouse with interchangeable appearance includes a base, an inner shell, and multiple outer shells that fit together. The inner shell and the base are assembled to form the mouse body. The mouse body has a rounded and full outline and is short and compact. One of the outer shells is placed on the top of the mouse body and is detachably connected to the inner shell. The front or rear ends of the multiple outer shells are respectively provided with different three-dimensional patterns to fit or change the hamster-shaped appearance of the mouse body.

[0007] By adopting the above technical solution, the mouse is assembled and fixed by the base and inner shell through an adapter structure, forming a rounded, full, short and compact main body outline, ensuring comfortable grip. Users can replace the outer shell with different three-dimensional patterns to match or change the hamster-shaped appearance theme of the mouse, and combine them to achieve diverse visual effects, meet users' needs for personalized or scenario-based decoration, and thus improve the user experience.

[0008] Preferably, the inner wall of the outer shell extends vertically downward with a plurality of first protrusions having a sloping cylindrical structure, and the plurality of first protrusions are evenly distributed along the axis of symmetry of the outer shell. The bottom end of the inner wall of the outer shell is provided with a plurality of second protrusions having a square structure at intervals. The upper surface and outer wall of the mouse body are respectively provided with first grooves and second grooves with matching shapes corresponding to the first protrusions and the second protrusions.

[0009] By adopting the above technical solution, the complementary geometry of the slot blocks enables convenient replacement and reliable fixation of the outer shell, while maintaining the overall appearance of the mouse body.

[0010] Preferably, the first protrusion has an annular mounting step at its end, and the second protrusion has an arc-shaped guide surface at its planar connection point.

[0011] By adopting the above technical solution, the annular step, as an axial positioning structure, can ensure the precise alignment of the shell and the mouse body. The arc surface reduces insertion resistance through smooth transition, reduces assembly difficulty, achieves a "blind insertion" effect, reduces assembly wear, and extends the service life of the components.

[0012] Preferably, the base and the inner shell are fixed together by an integrally formed clip-hole structure.

[0013] By adopting the above technical solution, the card strip-card hole structure achieves quick assembly and disassembly and tight connection through nesting, and the one-piece molding process has no splicing gaps, taking into account both assembly convenience and deformation resistance.

[0014] Preferably, the base is provided with a double-layer main control PCBA circuit board, wherein the lower main control PCBA circuit board is provided with a sensor and a battery compartment, and the upper main control PCBA circuit board is provided with a roller, an encoder, a rotating shaft seat and multiple push-button switches. The roller is rotatably connected to the rotating shaft seat through a rotating shaft. The left end of the rotating shaft of the roller is inserted into the encoder, and the right end is placed on one of the push-button switches.

[0015] By adopting the above technical solutions, the separate layout of the upper and lower main control PCBA circuit boards can reduce high-frequency signal interference, facilitate fault location, and the integrated design of the rotating shaft ensures that the roller action is synchronously transmitted to the encoder and key switch, reducing response delay.

[0016] Preferably, the lower surface of the base is provided with feet, a battery cover, a receiver slot and a switch. The feet are symmetrically arranged at the front and rear ends of the lower surface of the base. The battery cover covers the opening of the battery compartment. The receiver slot holds the receiver. The switch is electrically connected to the main control PCBA circuit board and can provide three signal receiving modes: Bluetooth, WIFI and OFF. The lower surface of the base also has a mouse hole corresponding to the sensor.

[0017] By adopting the above technical solution, a complete power supply unit is formed, which ensures that the sensor signal is unobstructed while stabilizing the equipment. The receiver and the switch work together to realize multi-mode wireless signal reception, which is suitable for different usage scenarios.

[0018] Preferably, the outer casing surface is provided with a left button area, a right button area and a DPI button area, and a roller opening is provided at the connection between the left button area and the right button area for the roller to pass through, and the DPI button area is adjacent to the roller opening.

[0019] By adopting the above technical solution, the three-button partition design is clearly defined, effectively reducing accidental touches. Users can click on the corresponding function area and trigger signals through the button switches on the main control PCBA circuit board, thereby realizing the relevant command output and improving operating efficiency.

[0020] Preferably, the inner shell has a roller opening and three button holes corresponding to the roller, left button area, right button area and DPI button area, respectively. Each of the three button holes has a semi-enclosed button cover integrally formed, and each of the three button covers has a cross-shaped button pressing block integrally formed at the bottom for triggering the button switch.

[0021] By adopting the above technical solutions, the holes and the functional areas of the outer shell are strictly aligned to ensure intuitive operation. The cross-shaped button pressure block is precisely matched with the button switch, and the four-way force is evenly applied for triggering. The semi-enclosed button cover retains the button pressing travel space, which comprehensively improves the operation accuracy.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The mouse consists of a base and an inner shell that are assembled and fixed together by an adapter structure to form a rounded, full, short and compact main body outline, ensuring comfortable grip. Users can replace the outer shell with different three-dimensional patterns to match or change the hamster-shaped appearance theme of the mouse, and combine them to achieve diverse visual effects, meet users' needs for personalized or scenario-based decoration, and thus improve the user experience. 2. The complementary geometry of the slots between the outer shell and the mouse body allows for convenient replacement and reliable fixation of the outer shell, while maintaining the overall appearance of the mouse; 3. The annular step of the first protrusion serves as an axial positioning structure, ensuring precise alignment between the outer shell and the mouse body. The second protrusion reduces insertion resistance and assembly difficulty through the smooth transition of the arc surface, achieving a "blind insertion" effect, reducing assembly wear, and extending the service life of the components.

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] This application discloses a mouse with interchangeable appearance. (See also...) Figure 1-2 A mouse with interchangeable appearance includes a base 22, an inner shell 21 and multiple outer shells 1 that fit together. The inner shell 21 and the base 22 are combined to form the mouse body 2. The outline of the mouse body 2 resembles a hamster. One of the outer shells 1 is placed on the top of the mouse body 2 and is detachably connected to the inner shell 21.

[0033] Correspondingly, the mouse is assembled and fixed by the base 22 and the inner shell 21 through the adapter structure, forming a rounded, full, short and compact main body outline to ensure grip comfort, and the fixed connection through the adapter structure provides stable support for the internal components.

[0034] Furthermore, in this embodiment, a total of three shells 1 are provided, the front ends of which are respectively formed into star-shaped, pig-nose-shaped and round-mouth-shaped three-dimensional patterns through an integral molding process. The rear end of the shell 1 with the round-mouth-shaped three-dimensional pattern can be fitted with a tail accessory. Users can change or better fit the hamster-shaped appearance theme of the mouse by replacing the shells 1 with different three-dimensional patterns.

[0035] In summary, this device, through its modular shell design, allows for diverse visual effects and flexible customization of the device's appearance, meeting users' needs for personalized or scenario-based decoration and effectively enhancing the user experience.

[0036] Specifically, refer to Figure 3-4 The inner wall of the outer shell 1 has a plurality of first protrusions 15 with a sloping cylindrical structure extending vertically downward. The plurality of first protrusions 15 are evenly distributed along the axis of symmetry of the outer shell 1. The bottom of the inner wall of the outer shell 1 has a plurality of second protrusions 16 with a square structure arranged circumferentially and at intervals. The first protrusions 15 and the second protrusions 16 are both injection molded. The upper surface and the outer side wall of the mouse body 2 are respectively provided with first grooves 23 and second grooves 24 with matching shapes corresponding to the first protrusions 15 and the second protrusions 16.

[0037] Therefore, the inclined surface design of the first protrusion 15 can guide the housing 1 to be accurately positioned, and the cylindrical structure provides rotational freedom, which facilitates automatic alignment during disassembly and assembly; the square structure of the second protrusion 16 restricts the rotation angle, ensuring that the housing 1 will not shift after being fixed, thus enhancing stability; through the complementary geometry of the groove blocks, it is ensured that the fit can be kept consistent when different housings 1 are replaced, reducing the uneven appearance caused by misalignment, and realizing convenient replacement and reliable fixation of the housing 1.

[0038] Furthermore, the end of the first protrusion 15 is provided with an annular mounting step 151, which serves as an axial positioning structure. Through minute tolerance compensation, it ensures the precise alignment of the outer shell 1 and the mouse body 2. The mounting step 151 can also absorb the impact force during assembly, protect the inner wall protrusion structure, and reduce the risk of loosening caused by frequent disassembly and assembly.

[0039] Meanwhile, the second protrusion 16 has an arc-shaped guide surface 161 at its planar connection point. This guide surface generates a progressive contact force during assembly and reduces insertion resistance through a smooth transition, ensuring gradual engagement between the protrusion and the groove, reducing assembly difficulty, and achieving a "blind insertion" effect. The arc-shaped guide surface 161 also reduces rigid collisions with the edge of the groove, reducing wear and extending the service life of the component.

[0040] On the other hand, the base 22 and the inner shell 21 are fixed by a one-piece molded clip-hole structure 214. This structure achieves rigid limiting and load distribution through nesting, without the need for additional tools. It can ensure a tight fit of the connection parts, reduce displacement caused by vibration or external force, facilitate quick disassembly and assembly and stable connection. Moreover, the one-piece molding process has no splicing gaps, eliminates weak points in the connection, and takes into account both assembly convenience and deformation resistance.

[0041] Specifically, refer to Figure 5-7In this embodiment, a double-layer main control PCBA circuit board 3 is fixed on the base 22. The lower main control PCBA circuit board 3 is equipped with a sensor 35 and a battery compartment 224. The upper main control PCBA circuit board 3 is equipped with a roller 31, an encoder 33, a rotating shaft seat 32, and four push-button switches 34. The four push-button switches 34 are a left button switch, a middle button switch, a right button switch, and a DPI button switch. The roller 31 is rotatably connected to the rotating shaft seat 32 through a rotating shaft. The left end of the rotating shaft is inserted into the encoder 33, and the right end is placed on the middle button switch.

[0042] Correspondingly, the upper and lower layer separation layout of the main control PCBA circuit board 3 fully optimizes space utilization, reduces high-frequency signal interference, and facilitates fault location; the sensor 35 captures the relative position change between the bottom of the mouse and the contact surface in real time, records information such as movement direction and distance, thereby ensuring the accuracy of cursor movement and assisting the upper layer circuit in decision-making; the battery compartment 224 forms a complete power supply unit after the battery is inserted, which can power the entire device.

[0043] Furthermore, when the scroll wheel 31 rotates, it drives the encoder 33 to generate pulse signals through the rotating shaft, realizing the digital detection of the scrolling direction. The right end of the rotating shaft of the scroll wheel 31 presses against the button switch 34, forming a dual triggering mechanism of mechanical and electrical signals, realizing the clicking function of the middle mouse button. This integrated design ensures that the movement of the scroll wheel 31 is synchronously transmitted to the encoder 33 and the button switch 34, reducing the response delay.

[0044] Meanwhile, the lower surface of the base 22 is equipped with feet 222, a battery cover 225, a receiver slot 226, and a switch 223. The feet 222 are symmetrically attached to the front and rear ends of the lower surface of the base 22, providing anti-slip support and shock absorption to ensure the stability of the device and reduce the risk of scratches on the contact surface. The battery cover 225 is placed over the opening of the battery compartment 224 to fix the battery and protect it from dust, making it easy to replace or maintain the battery. The receiver slot 226 locks the receiver in place to ensure the stability of signal transmission and reduce the occurrence of receiver loss. The switch 223 is electrically connected to the main control PCBA circuit board 3 and can provide three signal reception modes: Bluetooth, WIFI, and OFF. It supports wireless connection of the device to different terminals or complete disconnection of signal reception to save power. The lower surface of the base 22 also has a mouse hole 221 corresponding to the sensor 35, allowing the sensor 35 to capture surface image changes in real time through the mouse hole 221 using optical or laser technology to assist in cursor positioning.

[0045] In addition, the surface of the outer casing 1 is provided with a left button area 11, a right button area 12 and a DPI button area 14. The connection between the left button area 11 and the right button area 12 is provided with a roller 31 opening 13 through which the roller 31 can pass. The DPI button area is adjacent to the roller 31 opening 13.

[0046] Therefore, the three-button partition design has a clear functional division, which can effectively reduce accidental touches. After the user clicks the corresponding button area, the button switch 34 on the main control PCBA circuit board 3 is pressed down, thereby triggering a signal and outputting relevant instructions. The scroll wheel 31 opening 13 connects to the left / right button area 12, allowing the scroll wheel 31 to pass through the outer shell 1 and maintain rotational freedom. The DPI button is designed close to the scroll wheel 31 opening 13, which facilitates concentrated operation in the user's thumb area, thus improving overall operating efficiency.

[0047] Furthermore, the inner shell 21 has a roller 31 opening 13 and three button holes 211 respectively corresponding to the roller 31, the left button area 11, the right button area 12 and the DPI button area 14. Each of the three button holes 211 has a semi-enclosed button cover 212 integrally formed. Each of the three button covers 212 has a cross-shaped button pressing block 213 integrally formed at the bottom for triggering the button switch 34.

[0048] Therefore, the holes correspond precisely to the functional areas of the outer casing 1, forming independent trigger channels to ensure intuitive operation; the semi-enclosed button cover 212 reduces dust entry by covering the upper part of the button hole 211, while retaining the button's pressing travel space; the cross-shaped button pressure block 213 is precisely matched with the button switch 34, and through uniform triggering by four-way force, it improves the button response rate and comprehensively improves the operation accuracy.

[0049] The implementation principle of a mouse with interchangeable appearance according to this application embodiment is as follows: The mouse consists of a base 22 and an inner shell 21 assembled and fixed together by an adapter structure, forming a rounded, full, short, and compact main body outline, and is fixedly connected by the adapter structure. It has multiple outer shells 1, the front ends of which are formed with different types of three-dimensional patterns through an integrated molding process. Users can change or better match the hamster-shaped appearance theme of the mouse by replacing the outer shells 1 containing different three-dimensional patterns. This device, through its modular outer shell 1 design, achieves diverse visual effects and flexible customization of the device's appearance, meeting users' needs for personalized or scenario-based decoration and effectively improving the user experience.
