Description

Technical Field

[0001] This utility model relates to the field of mouse technology, and more specifically, to self-lubricating PTFE feet for the bottom of a mouse. Background Technology

[0002] In the field of mouse technology, mouse feet are a key component affecting the user experience, and their performance is crucial. With the rapid development of computer technology and users' ever-increasing demands for precision and comfort in mouse operation, the design of mouse feet is constantly evolving. Traditional mouse feet are mostly made of a single material, such as ordinary plastic or simple PTFE. These feet have many limitations in use. For example, ordinary plastic feet have a high coefficient of friction, resulting in less smooth mouse movement and failing to meet users' needs for high-precision operation. Especially in scenarios such as e-sports games where mouse control is extremely demanding, this stuttering can seriously affect the player's gaming experience. While early PTFE material feet reduced the coefficient of friction to some extent, their wear and tear becomes increasingly apparent with increased use, resulting in a shorter lifespan.

[0003] For example, patent application number 202210253907.3 describes a composite mouse foot pad. However, this composite mouse foot pad still has shortcomings in terms of self-lubrication, failing to continuously and effectively reduce the coefficient of friction during mouse use to meet the needs of long-term, high-precision operation. Furthermore, its structure and design may be susceptible to contaminants in complex environments, such as dusty environments, leading to performance degradation. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating PTFE mouse foot pad to solve the problem that the foot pads mentioned in the background art still have shortcomings in self-lubrication function and cannot continuously and effectively reduce the coefficient of friction during mouse use to meet the needs of long-term, high-precision operation.

[0005] To achieve the above objectives, this utility model provides a self-lubricating PTFE mouse foot, including a foot pad. The foot pad is installed on the bottom surface of the mouse body. The foot pad has a three-layer structure, namely an adhesive layer, a main body layer, and a contact layer. The main body layer has a plurality of lubrication channels filled with a lubricating medium. The adhesive layer is located on the upper part of the main body layer and is used to bond and fix it to the bottom of the mouse body. The contact layer is located on the lower part of the main body layer and is used to contact the use surface of the mouse body.

[0006] This design utilizes a three-layer structure for the mouse feet, clearly defining the function of each layer. The adhesive layer secures the feet to the bottom of the mouse body, ensuring they won't detach during use; the main body layer contains lubrication channels and is filled with lubricating medium, forming the core of the self-lubricating function; the contact layer directly contacts the surface being used, transferring the lubricating medium to the contact surface. These layers work together to form a complete self-lubricating mouse feet system.

[0007] Preferably, the adhesive layer, the main body layer, and the contact layer are bonded and fixed in sequence. The main body layer is made of PTFE material, the adhesive layer is a waterproof adhesive material, and the contact layer is made of titanium dioxide particles with a micro-nano texture structure on the surface. The micro-nano texture structure includes uniformly distributed grooves and protrusions.

[0008] The main layer of this structure uses PTFE material, taking advantage of its low coefficient of friction and wear resistance; the adhesive layer uses waterproof adhesive material, ensuring both fixation and waterproofing; the contact layer uses titanium dioxide particles with a micro-nano textured structure, the titanium dioxide particles enhance wear resistance, and the micro-nano grooves and protrusions disperse contact pressure, reducing localized wear.

[0009] Preferably, the lubrication channels are spaced apart along the length or width of the main body layer, and the interval between adjacent lubrication channels is 1mm-5mm.

[0010] This feature incorporates lubrication channels spaced along the length or width of the main body layer, ensuring even distribution of the lubricating medium within the mouse feet. By carefully controlling the spacing between adjacent lubrication channels, it is guaranteed that different areas receive timely replenishment of lubricating medium during mouse movement.

[0011] Preferably, the main body layer has a protruding side strip integrally formed on its bottom side, and a honeycomb layer is installed on the inner side of the side strip. The lubrication channel has a drain outlet near the honeycomb layer. The lubrication medium in the lubrication channel enters the honeycomb layer through the drain outlet and leaks out from the honeycomb layer to the surface of the contact layer.

[0012] This design features a side strip at the bottom of the main layer that mates with the honeycomb layer, with the lubrication channel connected to the honeycomb layer via an outlet. When the lubricating medium flows out of the lubrication channel, it first enters the honeycomb layer, where its porous structure stores and evenly disperses the lubricating medium before it is transported to the contact layer surface.

[0013] Preferably, the honeycomb layer is made of an oleophilic porous material with a porosity of 60%-80% and a pore size range of 50-200 micrometers. The thickness of the honeycomb layer is 0.1-0.3 mm, which can effectively store and uniformly disperse the lubricating medium.

[0014] This honeycomb layer utilizes an oleophilic porous material. Its specific porosity, pore size range, and thickness design enable it to efficiently store lubricating media and achieve uniform dispersion of the lubricating media through capillary action and porous structure. The oleophilic material ensures good compatibility with the lubricating media.

[0015] Preferably, the lubricating medium is liquid lubricating oil or solid lubricating particles, and the cross-sectional shape of the lubrication channel is circular, elliptical, or polygonal.

[0016] This setting allows for the selection of either liquid lubricating oil or solid lubricating particles as the lubricating medium, with flexible configuration options to suit different usage requirements and performance characteristics. The circular, elliptical, or polygonal cross-sectional shape of the lubrication channel will affect the flow resistance, storage capacity, and seepage pattern of the lubricating medium.

[0017] Preferably, a soft pad layer is provided near the contact layer in the lubrication channel. When the contact layer is subjected to pressure, it can compress and deform the soft pad layer, thereby reducing the space in the lubrication channel and causing the lubricating medium to overflow outward.

[0018] This feature involves placing a padding layer near the contact layer in the lubrication channel. When the contact layer is subjected to pressure (such as the pressure generated when a mouse moves on a flat surface), the padding layer deforms, squeezing the lubrication channel and reducing the space within the channel, thereby forcing the lubricating medium to overflow.

[0019] Preferably, the cushion layer is made of silicone rubber material with a Shore hardness of 20-40A and a thickness of 0.05-0.15mm. When the contact layer is subjected to a pressure of 0.5-2N, it can generate an effective deformation compression lubrication channel.

[0020] This design specifies that the cushion layer is made of silicone rubber, and defines its Shore hardness, thickness, and the pressure range that triggers deformation. Silicone rubber has good elasticity and flexibility; the appropriate Shore hardness and thickness allow it to deform effectively under specific pressure, compressing the lubrication channels.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: The unique structure and materials of the PTFE feet on the bottom of this self-lubricating mouse give it excellent self-lubricating properties. It can continuously and stably lubricate the contact layer during movement, reduce the coefficient of friction, and make operation smoother and more precise. The titanium dioxide particles, micro-nano textures and nano-coatings of the contact layer, combined with the PTFE main layer, greatly enhance wear resistance and extend service life.

[0022] The waterproof adhesive layer ensures stable structural connections, making installation and replacement convenient and waterproof; the honeycomb layer, made of oleophilic porous material, can both store and disperse lubricating media and block contaminants, and the design of each layer adapts to different temperature and humidity environments; the precise design of each structural parameter enables precise control of the amount and speed of lubricating media seepage, avoiding leakage or insufficiency, and ensuring long-term stable self-lubricating function.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This invention provides self-lubricating PTFE feet for the bottom of a mouse, such as... Figure 1 , Figure 2 As shown, the mouse includes a foot pad 1, which is installed on the bottom surface of the mouse body 2. The foot pad 1 has a three-layer structure, namely an adhesive layer 11, a main body layer 12, and a contact layer 13. The main body layer 12 has a plurality of lubrication channels 121, which are filled with a lubricating medium. The adhesive layer 11 is located on the upper part of the main body layer 12 and is used to bond and fix it to the bottom of the mouse body 2. The contact layer 13 is located on the lower part of the main body layer 12 and is used to contact the use surface of the mouse body 2.

[0026] By designing a three-layer structure for the mouse feet 1, the function of each layer is clearly defined. The adhesive layer 11 is used to fix the mouse feet to the bottom of the mouse body 2, ensuring that the feet will not fall off during use; the main body layer 12 contains lubrication channels 121 and is filled with lubricating medium, which is the core part to achieve the self-lubricating function; the contact layer 13 directly contacts the use surface of the mouse body 2, transferring the lubricating medium to the contact surface. Each layer works together to form a complete self-lubricating mouse feet system. This design establishes the basic structural framework for self-lubricating mouse feet, providing an overall solution for achieving self-lubrication, fixed installation, and contact use functions, enabling the mouse to receive continuous lubrication during movement and improving the smoothness and stability of operation.

[0027] In this embodiment, as Figure 2 As shown, the adhesive layer 11, the main body layer 12 and the contact layer 13 are bonded and fixed in sequence. The main body layer 12 is made of PTFE material, the adhesive layer 11 is a waterproof adhesive material, and the contact layer 13 is made of titanium dioxide particles and has a micro-nano-level texture structure on its surface. The micro-nano-level texture structure includes uniformly distributed grooves and protrusions.

[0028] The main body layer 12 is made of PTFE material, utilizing its low coefficient of friction and wear resistance. The adhesive layer 11 uses a waterproof adhesive material, ensuring both fixation and waterproofing. The contact layer 13 uses titanium dioxide particles with a micro-nano textured surface. The titanium dioxide particles enhance wear resistance, while the micro-nano grooves and protrusions disperse contact pressure, reducing localized wear. Through the selection of specific materials and structural design, the wear resistance, waterproofing, and structural stability of the feet are enhanced. This reduces the wear rate of the feet during use, extending their service life. The waterproof design prevents external moisture from affecting the feet's performance, and the micro-nano textured structure improves the stability and smoothness of the contact between the feet and the surface.

[0029] Specifically, such as Figure 3 As shown, lubrication channels 121 are spaced apart along the length or width of the main body layer 12, and the interval between adjacent lubrication channels 121 is 1mm-5mm.

[0030] Lubrication channels 121 are spaced apart along the length or width of the main body layer 12 to ensure that the lubricating medium is evenly distributed within the mouse feet. The spacing between adjacent lubrication channels 121 is controlled to be 1mm-5mm to ensure that different areas receive timely replenishment of lubricating medium during mouse movement. This guarantees uniform seepage of the lubricating medium onto the surface of the mouse feet, providing stable lubrication in all directions and preventing localized insufficient or excessive lubrication, thus improving the consistency and smoothness of mouse operation.

[0031] Furthermore, such as Figure 3As shown, a protruding side strip 122 is integrally formed on the bottom side of the main body layer 12. A honeycomb layer 124 is installed on the inner side of the side strip 122. A drain outlet 1211 is provided near the honeycomb layer 124 in the lubrication channel 121. The lubricating medium in the lubrication channel 121 enters the honeycomb layer 124 through the drain outlet 1211 and leaks out from the honeycomb layer 124 to the surface of the contact layer 13.

[0032] The protruding side strip 122, integrally formed and installed on the bottom side of the main body layer 12, cooperates with the inner honeycomb layer 124. A drain outlet 1211 is provided in the lubrication channel 121 near the honeycomb layer 124. When the lubricating medium flows out from the lubrication channel 121, it first enters the honeycomb layer 124. The porous structure of the honeycomb layer 124 stores and evenly disperses the lubricating medium before it is transported to the surface of the contact layer 13. This achieves orderly transmission and uniform dispersion of the lubricating medium, allowing for more uniform lubrication on the surface of the contact layer 13 and further improving the self-lubricating performance of the foot pad. Simultaneously, the honeycomb layer 124 can, to a certain extent, prevent dust and other debris from entering the foot pad, protecting the lubrication channel 121 and the lubricating medium, and extending the service life of the foot pad.

[0033] Furthermore, such as Figure 4 As shown, the honeycomb layer 124 is made of an oleophilic porous material with a porosity of 60%-80% and a pore size range of 50-200 micrometers. The thickness of the honeycomb layer 124 is 0.1-0.3 mm, which can effectively store and uniformly disperse the lubricating medium.

[0034] The honeycomb layer 124 is made of an oleophilic porous material with a porosity of 60%–80%, a pore size range of 50–200 micrometers, and a thickness of 0.1–0.3 mm. These specific parameters are designed to efficiently store the lubricating medium and achieve uniform dispersion of the lubricating medium through capillary action and the porous structure. The oleophilic material ensures good compatibility with the lubricating medium. The optimized ability of the honeycomb layer 124 to store and disperse the lubricating medium ensures a stable and continuous supply of the lubricating medium to the surface of the contact layer 13, maintaining the self-lubricating performance of the foot pad. The appropriate porosity and pore size ensure sufficient storage space while controlling the seepage rate of the lubricating medium, preventing leakage or insufficiency.

[0035] Furthermore, the lubricating medium is liquid lubricating oil or solid lubricating particles, and the cross-sectional shape of the lubrication channel 121 is circular, elliptical, or polygonal.

[0036] The lubricating medium can be either liquid lubricating oil or solid lubricating particles, and can be flexibly configured according to different usage requirements and performance characteristics. The cross-sectional shape of the lubrication channel 121 can be circular, elliptical, or polygonal; different cross-sectional shapes will affect the flow resistance, storage capacity, and seepage mode of the lubricating medium. A variety of lubricating media and channel cross-section options are provided, allowing users or manufacturers to select the most suitable lubricating medium and channel structure based on actual usage scenarios such as different operating forces and usage frequencies to achieve the best self-lubricating effect, enhancing the applicability and customizability of the foot pads.

[0037] Furthermore, such as Figure 3 As shown, a soft pad 123 is provided near the contact layer 13 in the lubrication channel 121. When the contact layer 13 is subjected to pressure, it can squeeze the soft pad 123 to deform, thereby reducing the space in the lubrication channel 121 and causing the lubricating medium to overflow.

[0038] A soft pad layer 123 is provided near the contact layer 13 in the lubrication channel 121. When the contact layer 13 is subjected to pressure, such as the pressure generated when the mouse moves on the surface, the soft pad layer 123 deforms, compressing the lubrication channel 121 and reducing the space within the channel, thereby forcing the lubricating medium to overflow. This achieves automatic control of the overflow of the lubricating medium based on the actual pressure during mouse use. The greater the pressure during mouse movement, the greater the deformation of the soft pad layer 123, and the more lubricating medium overflows, thus meeting the lubrication needs under different operating forces in real time and improving the accuracy and effectiveness of self-lubrication.

[0039] Furthermore, the cushion layer 123 is made of silicone rubber material with a Shore hardness of 20-40A and a thickness of 0.05-0.15mm. When the contact layer 13 is subjected to a pressure of 0.5-2N, it can generate effective deformation to compress the lubrication channel 121.

[0040] The soft pad layer 123 is made of silicone rubber with a Shore hardness of 20-40A and a thickness of 0.05-0.15mm. It can effectively deform when the contact layer 13 is subjected to a pressure of 0.5-2N, compressing the lubrication channel 121. Silicone rubber has good elasticity and flexibility; its suitable Shore hardness and thickness allow it to deform effectively under specific pressure. Precise control of the performance parameters of the soft pad layer 123 ensures that it can stably and reliably compress the lubrication channel 121 during normal mouse use, allowing the lubricating medium to overflow in the expected manner and amount. This guarantees the stability and consistency of the self-lubricating function, avoiding problems of insufficient or excessive lubrication due to unstable performance of the soft pad layer 123.

[0041] When using the self-lubricating PTFE feet of this invention, the adhesive layer 11 of the feet is first attached to the bottom surface of the mouse body 2. The waterproof adhesive material, with its specific adhesive strength, firmly fixes the feet 1 to the mouse body 2, ensuring that the feet will not fall off during subsequent use. At the same time, the waterproof performance can prevent external moisture from intruding and affecting the performance of the feet. When a user moves the mouse on the working surface, the contact layer 13 rubs against the surface, simultaneously applying pressure to the padding layer 123. When the pressure on the contact layer 13 reaches 0.5-2N, the silicone rubber material of the padding layer 123, with a Shore hardness of 20-40A and a thickness of 0.05-0.15mm, deforms, compressing the lubrication channel 121 and reducing the space within the channel. At this time, under pressure, liquid lubricating oil or solid lubricating particles in the lubrication channel 121 enter the honeycomb layer 124 through the outlet 1211 near the honeycomb layer 124. The honeycomb layer 124 is made of an oleophilic porous material with a porosity of 60%-80%, a pore size range of 50-200 micrometers, and a thickness of 0.1-0.3 mm. Utilizing its porous structure and capillary action, it stores and uniformly disperses the incoming lubricating medium. Subsequently, the lubricating medium seeps out from the honeycomb layer 124 to the surface of the contact layer 13. As the mouse continues to move, the lubricating medium on the surface of the contact layer 13 forms a lubricating film between the mouse feet and the surface being used, reducing the coefficient of friction and achieving a self-lubricating effect, making the mouse movement smoother. Simultaneously, the titanium dioxide particles and micro / nano-scale textured grooves and protrusions of the contact layer 13 disperse contact pressure, reducing localized wear. The nano-coating further enhances wear resistance and stain resistance, ensuring the mouse feet maintain good performance during prolonged use. Meanwhile, the lubrication channels 121, spaced 1mm-5mm apart along the length or width of the main body layer 12, ensure a continuous and even supply of lubricating medium to the contact layer 13 as the mouse moves in all directions, maintaining a stable self-lubricating effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
