Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of computer equipment and relates to a protection assembly and a touchpad. BACKGROUND

[0002] With the development of thin and high integration of notebook computers, the performance and durability of the touchpad as a core input component of human-computer interaction directly affect the user experience. However, the existing touchpad still has the following technical bottlenecks in material design and functional integration:

[0003] The traditional touchpad is mostly made of plastic, glass or metal substrate, and static electricity is easily accumulated due to long-term friction. Static electricity not only causes touch signal interference (such as cursor drift and false touch), but also may damage internal sensitive elements through circuit coupling. Similarly, long-term contact with fingers will easily cause scratches and a decrease in gloss on the surface of the touchpad, affecting the touch and appearance. User hand sweat and sebum residues can breed bacteria (such as Staphylococcus aureus and Escherichia coli), forming a health hazard.

[0004] Therefore, how to provide a protection assembly and a touchpad to improve the durability of the touchpad has become a technical problem to be solved. CONTENT OF THE INVENTION

[0005] In order to overcome the problems in the related art, the present application aims to provide a protection assembly and a touchpad which can improve the durability of the touchpad.

[0009] A conductive layer, which is arranged on the outer periphery of the antistatic layer;

[0010] An antibacterial wear-resistant layer, which is arranged on the side of the antistatic layer away from the touchpad main body;

[0011] The antistatic layer is completely projected on the touchpad main body in the vertical direction, and the horizontal cross-sectional area of the avoidance slot is smaller than the corresponding cross-sectional area of the touchpad main body.

[0012] The technical solution reduces the negative effects of static accumulation through the conductive layer in cooperation with the antistatic layer, and increases the antibacterial performance of the wear-resistant layer through the antibacterial wear-resistant layer, thereby improving the durability of the touchpad.

[0013] The conductive layer is multiple conductive sheets, and the conductive sheets are distributed along the outer periphery of the antistatic layer in a circumferential direction at equal intervals.

[0014] The antistatic layer and the conductive layer are provided with an insulating isolation layer between the sensing area of the touchpad main body, so as to prevent charge interference with the capacitance sensing function.

[0015] The conductive layer is indium tin oxide.

[0016] The antistatic layer is polyurethane containing an antistatic agent.

[0017] The protective layer is embedded in the inside of the avoiding groove and is used for supporting the antibacterial wear-resistant layer.

[0018] The antibacterial wear-resistant layer is a combination of an antibacterial agent, a wear-resistant coating and an adhesive, or the antibacterial wear-resistant layer comprises a wear-resistant layer, an antibacterial layer and an adhesive layer arranged in sequence.

[0019] The wear-resistant coating is a polymer compatible with the antibacterial agent, and the adhesive is an adhesive compatible with the antibacterial agent and the wear-resistant coating.

[0020] The antibacterial agent, the wear-resistant coating and the adhesive are cured by ultraviolet rays.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in some embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0031] The present embodiment discloses a protective assembly for the surface protection of a touchpad body 1, as shown in the figure, comprising: Figures 1-4

[0032] An antistatic layer 3, the avoiding groove 31 is opened through the antistatic layer 3, and the geometric center of the avoiding groove 31 coincides with the geometric center of the antistatic layer 3;

[0033] A conductive layer 2, the conductive layer 2 is arranged on the outer periphery of the antistatic layer 3;

[0034] An antibacterial wear-resistant layer 4, the antibacterial wear-resistant layer 4 is arranged on the side of the antistatic layer 3 away from the touchpad body 1;

[0035] Wherein, the orthographic projection of the antistatic layer 3 in the vertical direction completely covers the touchpad body 1, and the horizontal cross-sectional area of the avoiding groove 31 is smaller than the corresponding cross-sectional area of the touchpad body 1.

[0036] It should be noted that the antistatic layer 3 is arranged in the non-sensing area of the touchpad body 1 to avoid affecting the use of the touchpad body 1, and the outer edge part extending outwardly compared with the touchpad body 1 is shielded inside the computer shell. Similarly, the conductive layer 2 is also arranged inside the computer shell and finally connected with the grounding line to avoid the negative effects caused by static accumulation. The antibacterial wear-resistant layer 4 as a layer in contact with the user has good wear resistance and antibacterial property.

[0037] As shown in the figure, the conductive layer 2 is a plurality of conductive sheets, and the conductive sheets are distributed along the outer periphery of the antistatic layer 3 in a circumferential direction at equal intervals. Figures 1-4 As shown in the figure, the conductive layer 2 is a plurality of conductive sheets, and the conductive sheets are distributed along the outer periphery of the antistatic layer 3 in a circumferential direction at equal intervals.

[0038] Figures 1-4 ​​As shown, an insulating isolation layer is provided between the antistatic layer 3 and the conductive layer 2 and the sensing area of ​​the touch panel body 1 to prevent charge from interfering with the capacitive sensing function.

[0039] It should be noted that setting an insulating layer can prevent the charge in the antistatic layer 3 from moving to the sensing area of ​​the touchpad body 1, thus preventing the charge from affecting the capacitive sensing function.

[0040] like Figures 1-4 As shown, the conductive layer 2 is indium tin oxide.

[0041] like Figures 1-4 As shown, the antistatic layer 3 is a polyurethane containing an antistatic agent.

[0042] It should be noted that the conductive layer 2 uses a material with low capacitance interference, the antistatic layer 3 has a certain resistivity, and the conductive layer 2 and the antistatic layer 3 have the same height or have a height difference.

[0043] like Figure 2 As shown, it also includes a protective layer 41, which is embedded inside the relief groove 31 and serves to support the formation of the antibacterial and wear-resistant layer 4.

[0044] It should be noted that after the antistatic layer 3 is set, there is a height difference between the surface of the touchpad body 1 and the antistatic layer 3. At this time, the addition of the antibacterial and wear-resistant layer 4 will eventually result in a height difference on the surface of the touchpad body 1. Therefore, the protective layer 41 is used to fill the gap to keep the touchpad body 1 flat.

[0045] like Figure 3 As shown, the antibacterial wear-resistant layer 4 is a combination of antibacterial agent, wear-resistant coating and adhesive, or the antibacterial wear-resistant layer 4 includes a wear-resistant layer 42, an antibacterial layer 421 and an adhesive layer arranged in sequence.

[0046] like Figures 1-4 As shown, the wear-resistant coating is a polymer compatible with the antibacterial agent, and the adhesive is an adhesive compatible with both the antibacterial agent and the wear-resistant coating.

[0047] like Figures 1-4 As shown, the antibacterial agent, wear-resistant coating, and adhesive are cured by ultraviolet light.

[0048] It should be noted that when combining antibacterial agents, wear-resistant coatings, and adhesives, the antibacterial agents, wear-resistant coatings, and adhesives must be mixed first, and then cured by heating or ultraviolet light to ensure that the three are tightly bonded and that the antibacterial agent is stably embedded.

[0049] A type of touchpad, such as Figures 1-4 As shown, it includes a touchpad body 1 and a protective component as described in the first aspect.

[0050] Working principle: through the conductive layer 2 cooperate with antistatic layer 3 reduce the negative effects of static accumulation, through the antibacterial wear-resistant layer 4 increase the wear-resistant layer antibacterial properties, improve the durability of touch panel.

[0051] Embodiments of the application have been described above, with the understanding that these embodiments are exemplary only and are not exhaustive of all embodiments of the application. Many modifications and variations of the described embodiments are possible in light of the above teachings. It is therefore to be understood that within the scope of the described embodiments and the spirit of the application, many alternatives, modifications, and variations will be apparent to those of ordinary skill in the art. The selection of words used in this document is intended to best explain the principles of the embodiments, the practical application, or the improvement over the technology in the market, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
