Description

Technical Field

[0001] This utility model relates to the field of computer peripherals technology, and in particular to a mouse pad. Background Technology

[0002] A mouse pad is placed under the mouse and is mainly used to provide users with a smooth, moderately firm sliding feel in the area where the mouse slides, while preventing the reflection and refraction of light from the desktop surface from affecting the mouse's sensor positioning.

[0003] Mouse pads in the prior art are often made in two ways: one is by stacking silicone sheets and textile fabrics of the same shape and size, and then hot-pressing them into shape using a mold with a certain pressure and temperature; the other is by stacking silicone sheets and textile fabrics of the same shape and size, and then sewing the edges together with stitching thread.

[0004] Mouse pads made using the two methods described above will have significant drawbacks when applied to everyday life: Mouse pads made by hot-pressing textile fabric with silicone are prone to problems such as textile fabric delamination, edge curling, silicone aging, and substrate deformation due to factors such as human hand or mouse friction, changes in environmental temperature and humidity, usage patterns and frequency, and the properties of the materials themselves during long-term use. On the other hand, mouse pads made by stitching textile fabric with silicone sheets are prone to edge thickness issues when used in real life. Due to the dense stitching, the edges of the mouse pad are significantly thicker than other areas, often resulting in curling edges. This affects the overall flatness of the mouse pad, making it difficult for users who are sensitive to mouse gliding (such as e-sports players and artists) to have a good experience. Furthermore, the stitching on these mouse pads is prone to wear and tear, pilling, and fuzzing after long-term use, leading to a decrease in overall visual appeal and poor aesthetics. Utility Model Content

[0005] The main purpose of this utility model is to provide a mouse pad that has invisible edges under normal use, uniform thickness in all parts, and good flatness.

[0006] To achieve the above objectives, this utility model proposes a mouse pad with an invisible edge structure. The mouse pad includes a substrate layer and a surface layer. The surface layer covers the top surface of the substrate layer and folds into the substrate layer and fits into the bottom surface of the substrate layer.

[0007] Optionally, the mouse pad also includes an adhesive layer disposed between the surface layer and the substrate layer to bond the two together.

[0008] Optionally, the substrate is made of polyurethane foam sheet and the surface layer is made of textile fabric; the surface layer includes a surface layer body and a surface layer fold, the surface layer body and the substrate have the same shape and size; the surface layer fold is arranged around the surface layer body and the surface layer body is integrally formed.

[0009] Optionally, the substrate layer has a fitting groove, which is formed along the edge of the substrate layer on the bottom surface of the substrate layer. When the surface layer is folded towards the substrate layer, the folded edge of the surface layer is embedded in the fitting groove.

[0010] Optionally, the depth of the fitting groove is not less than the height of the surface layer.

[0011] Optionally, the surface layer fold includes a straight edge, which is located at the edge where the surface layer body is presented as a straight line.

[0012] Optionally, the width of the fitting groove is not less than the height of the straight edge.

[0013] Optionally, the surface fold also includes a serrated edge, which is located at the curved edge of the surface body. The serrated edge includes at least one serration, the root of each serration is in contact with the curved edge of the surface body, and the tip of each serration is away from the surface body.

[0014] Optionally, the width of the fitting groove is not less than the tooth height of the serrated edge.

[0015] The beneficial effects of this utility model are as follows: The mouse pad provided by this utility model has a folded edge that is bent and fitted into the bottom surface of the substrate layer. On the one hand, when the mouse pad is in normal use, the edge of the surface layer is attached to the external desktop along with the bottom surface of the substrate layer, and the user cannot see the folded edge of the surface layer. The folded edge of the surface layer is "invisible", and the mouse pad as a whole has good visual consistency. On the other hand, since the fitting position of the surface layer and the substrate layer is located on the bottom surface of the substrate layer, it is not touched by the human hand or mouse during normal use, which can effectively avoid problems such as edge lifting and glue detachment caused by repeated friction of the human hand or mouse during the use of the mouse pad. Furthermore, the folded surface layer and the substrate layer are interlocked, and the structure is simple and easy to manufacture, which makes it easier for technicians to manufacture mouse pads with better flatness.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0025] Please see Figure 1-4This embodiment provides a mouse pad with an invisible edge structure. The mouse pad includes a substrate layer 1 and a surface layer 2. The surface layer 2 covers the top surface of the substrate layer 1 and folds over the substrate layer 1, fitting into the bottom surface of the substrate layer 1. In this embodiment, the surface layer 2 covers the substrate layer 1, and after folding the surface layer 2 over the substrate layer 1 and embedding it into the bottom surface of the substrate layer 1, the cuts of the substrate layer 1, the cuts of the surface layer 2, and the fitting position of the surface layer 2 and the substrate layer 1 are all hidden on the bottom surface of the substrate layer 1. When the user uses the mouse pad provided in this embodiment, the mouse pad will be placed on an external desktop with the substrate layer 1 facing down and the surface layer 2 facing up. The fitting part of the surface layer 2 and the substrate layer 1 will be pressed against the external desktop along with the bottom surface of the substrate layer 1, and will be located at the very bottom of the mouse pad. The hand and mouse will only move on the top surface of the surface layer 2, and the mouse pad will not come into contact with the surface without being flipped. Touching the bottom surface of the substrate layer 1, this structural design effectively ensures a stable connection between the surface layer 2 and the substrate layer 1 by wrapping the surface layer 2 around the substrate layer 1. On the other hand, it hides the connection point between the surface layer 2 and the substrate layer 1, ensuring that there are no cuts or breaks in the frequently touched areas when the user uses the mouse pad normally. This effectively avoids deformation of cuts or delamination of breaks caused by repeated movement and friction of the hand or mouse. Furthermore, when the surface layer 2 is folded over to the bottom surface of the substrate layer 1, the interlocking structure of the surface layer 2 and the substrate layer 1 is pressed under the substrate layer 1 when the mouse pad is placed on an external desktop. The user cannot see the interlocking structure, which can give the user a "hidden edge" user experience.

[0026] Please see Figure 1-4 In this specific embodiment, the mouse pad further includes an adhesive layer 3, which is disposed between the surface layer 2 and the substrate layer 1 to bond the two together. In practice, those skilled in the art can use TPU hot melt adhesive provided in the prior art as the adhesive layer 3 to implement this technical solution.

[0027] Please see Figure 5-7In this specific embodiment, the substrate layer 1 is made of polyurethane foam sheet. As a microporous foaming material, polyurethane foam has excellent thermal insulation, lightweight and softness, chemical corrosion resistance, and shock absorption properties. Using polyurethane foam sheet to make the substrate layer 1 can provide users with a comfortable tactile experience. In specific implementations, the substrate layer 1 can be manufactured into shapes with regular geometric edges, such as squares, rectangles, and regular polygons, or it can be manufactured into shapes with irregular edges, such as cartoon patterns or design patterns. The surface layer 2 is made of textile fabric; the surface layer 2 includes a surface layer body 21 and a surface layer folded edge 22. The surface layer body 21 has the same shape and size as the substrate layer 1; the surface layer folded edge 22 is arranged around the surface layer body 21, and the surface layer folded edge 22 is integrally formed with the surface layer body 21. Keeping the surface layer body 21 the same shape and size as the substrate layer 1, when the surface layer 2 and the substrate layer 1 are bonded, the surface layer body 21 is adapted to the substrate layer 1, and the surface layer body 21 is attached to the top surface of the substrate layer 1.

[0028] Please see Figure 1-4 In this specific embodiment, the substrate layer 1 has a fitting groove 11. The fitting groove 11 is formed on the bottom surface of the substrate layer 1 along the edge of the substrate layer 1. When the surface layer is folded towards the substrate layer 1, the folded edge 22 of the surface layer is embedded in the fitting groove 11. From one perspective, the interlocking groove 11 is located on the bottom surface of the substrate 1. The position of the interlocking groove 11 is the position where the surface layer 2 and the substrate 1 interlock. That is, the surface layer 2 and the substrate 1 interlock with each other on one side of the bottom surface of the substrate 1, relying on the interlocking groove 11. Since the mouse pad will be placed on an external desktop with the substrate 1 facing down and the surface layer 2 facing up during actual use, the bottom surface of the substrate 1 will be in contact with the external desktop, and the user's hand or mouse will touch the top surface of the surface layer 2 and slide on the top surface of the surface layer 2. In this way, the interlocking structure between the surface layer 2 and the substrate 1, which is located on the bottom surface of the substrate 1, will be in a "hidden" state, and the user will not be able to find it without flipping the mouse pad. From another perspective, the interlocking groove on the bottom surface of the substrate 1 will provide a clearance for the surface layer 2, and the edge of the surface layer 2 will be bent to the substrate. After the bottom layer 1 is laid down, the recessed groove 11 provides space for the folded edge 22 of the surface layer. The folded edge 22 is embedded in the recessed groove 11 and fits against the substrate layer 1. The cut of the folded edge 22 is hidden in the recessed groove 11. When the user drags the mouse pad along the external desktop, it is difficult to directly rub against the cut of the folded edge 22. Once the surface layer 2 and the substrate layer 1 are bonded, they are difficult to peel off. It can be seen that the recessed groove 11 can effectively connect the surface layer 2 and the substrate layer 1, and also provide space for the folded edge 22 that is bent to the bottom side of the substrate layer 1, improving the overall flatness of the mouse pad. It also avoids the folded edge 22 that is folded to the bottom of the substrate layer from thickening the edge of the mouse pad and causing the edge of the mouse pad to curl and bulge, giving the user a smooth and flat mouse pad experience.

[0029] Please see Figure 1-4In specific manufacturing, the groove depth d1 of the fitting groove 11 is designed to be no less than the layer height d2 of the surface layer 2. In this specific embodiment, the technician can choose that the groove depth d1 of the fitting groove 11 is equal to the layer height d2 of the surface layer 2. That is, after the surface layer folded edge 22 is embedded in the fitting groove 11, the surface of the surface layer folded edge 22 will be flush with the surface of the substrate layer 1. The thickness of the fitting position of the surface layer 2 and the substrate layer 1 will be completely consistent with the thickness of other areas. When the human hand or mouse slides on the mouse pad provided in this specific embodiment, there will be no obvious protrusion, and there will be no obvious foreign object sensation at the wrist, which enhances the "invisible edge" feel of the mouse pad in terms of tactile sensation.

[0030] Please see Figure 1 , 5 -7. In this specific embodiment, the surface layer folded edge 22 includes a straight edge 221, which is disposed at the edge of the surface layer body 21 where it is a straight line. The groove width w1 of the fitting groove 11 is not less than the height h1 of the straight edge 221. As explained above, the substrate 1 can be manufactured into a shape with regular geometric edges, such as a square, rectangle, or regular polygon. If the substrate 1 is designed and manufactured into a thin sheet structure with regular geometric shapes, since the surface body 21 has the same shape and size as the substrate 1, the edge of the surface body 21 will also be straight. The straight edge 221 is set at the edge of the straight surface body 21 and folds directly along the edge of the surface body 21 to the bottom surface of the substrate 1, and is embedded in the matching fitting groove 11. In specific manufacturing, the groove width w1 of the fitting groove 11 is set to be equal to the height h1 of the straight edge 221. Then the cut of the surface 2 will fit exactly with the groove wall of the fitting groove 11, and the straight edge fold 221 is completely embedded in the fitting groove 11. There is no obvious excess at the joint between the surface 2 and the substrate 1, which visually enhances the "invisible edge" feel of the mouse pad.

[0031] Please see Figure 5-7In this specific embodiment, the surface layer fold 22 further includes a serrated edge 222. The serrated edge 222 is disposed at the curved edge of the surface layer body 21. The serrated edge 222 includes at least one serration, the root of each serration is in contact with the curved edge of the surface layer body 21, and the tip of each serration is away from the surface layer body 21. The groove width w1 of the fitting groove 11 is not less than the tooth height h2 of the serrated edge 22. As explained above, the substrate layer 1 can be manufactured into a shape with irregular edges, such as a cartoon pattern or a design pattern. For example, if the substrate layer 1 is designed and manufactured into a thin sheet structure with irregular geometric shapes, since the surface layer body 21 and the substrate layer 1 have the same shape and size, the edge of the surface layer body 21 will also be curved. The serrated edge 222 is disposed at the curved edge of the surface layer body 21. Each serration in the serrated edge 222 will take the arc line of the edge of the surface layer body 21 as the tooth root arc line and fold along the tooth root arc line. Folded onto the bottom surface of the substrate layer 1, it is embedded in the matching groove 11. Since each tooth in the serrated edge 222 is shaped with a wide root and a narrow tip, the two adjacent teeth will not overlap after folding. In specific manufacturing, the groove width w1 of the fitting groove 11 is set to be equal to the tooth height h2 of the serrated edge 222. Then, each tooth of the serrated edge 222 will be completely embedded in the fitting groove 11 after folding. There is no obvious excess at the joint between the surface layer 2 and the substrate layer 1, which visually enhances the "invisible edge" feel of the mouse pad.

[0032] Please see Figure 5-7 Specifically, in this embodiment, the substrate 1 is designed and manufactured as a rectangle with rounded corners, that is, the substrate 1 is designed and manufactured as a rectangle with two adjacent sides joined by rounded corners. The central angle of the rounded corner is 90° and the radius of the rounded corner is 10mm. The fitting groove 11 is formed along the edge of the substrate 1 on the bottom surface of the substrate 1. The groove width of the fitting groove 11 is 10mm, the groove depth d1 is 5mm, and the groove width w1 is 10mm. The surface layer body 21 has the same shape and size as the substrate 1. The layer height d2 of the surface layer 2 is 5mm. A straight edge 221 is provided corresponding to the straight edge of the substrate 1. The height h1 of the straight edge 221 is 10mm. A serrated edge 222 is provided corresponding to the rounded corner of the substrate 1. The tooth height h2 of the serrated edge 222 is 10mm.

[0033] Please see Figure 1 , 4 -5. Technicians can manufacture the mouse pad with the invisible edge structure described above using the following method, which specifically includes the following steps:

[0034] S1. A shaped substrate layer 1 is obtained by punching polyurethane foam sheet; specifically, a shaped substrate layer 1 with interlocking grooves 11 is cut from polyurethane foam sheet according to the finished product size using a laser cutter.

[0035] S2. Cut the textile fabric to obtain a surface layer 2 that is compatible with the substrate layer 1. The surface layer 2 includes a surface layer body 21, a straight edge 221 and a serrated edge 222. The surface layer body 21 is kept to be the same size and shape as the substrate layer 1. The height h1 of the straight edge 221 and the tooth height h2 of the serrated edge 222 are equal, which is equal to the groove width w1 of the fitting groove 11.

[0036] S3. Apply adhesive layer 3 to the bottom surface of surface layer 2, and use a jig to stack and hot-press substrate layer 1 and surface layer 2 so that surface layer body 21 and top surface of substrate layer 1 are attached and bonded together.

[0037] S4. Use a jig to fold the surface layer folded edge 22 to the bottom surface of the substrate layer 1, and embed the straight edge 221 and the serrated edge 222 in the surface layer folded edge 22 into the matching fitting groove 11 respectively.

[0038] S5. Use a jig to hot press again so that the surface layer fold 22 is attached and bonded to the bottom surface of the substrate layer 1.
