Description

Technical Field

[0001] This application relates to the field of structural component fixing technology, and in particular to a hot-melt fixing structure, a touch panel, and electronic products. Background Technology

[0002] Touchpads are common structural components in electronic products, such as laptops, where they are used for various operations. Current touchpads have a large number of parts, complex manufacturing processes, and a cumbersome assembly process, typically requiring multiple screws. This results in high design and manufacturing costs.

[0003] To address the aforementioned issues, a thermoplastic fixing method can be used to replace the existing screw assembly, thereby reducing costs. The thermoplastic fixing process involves melting a thermoplastic column at high temperature and then cooling and solidifying it to fasten the two parts together. Traditional thermoplastic fixing methods involve setting a thermoplastic column structure on the housing, placing the bracket on the housing, with the thermoplastic column extending approximately 1.5mm above the bracket, and then melting the thermoplastic column for fixation.

[0004] In traditional hot-melt fixing methods, there are gaps between the hot-melt pillars on the shell and the touchpad in the XY direction (horizontal direction). During hot-melt, they are pressed together in the Z direction (vertical direction), generating friction between the mushroom head and the touchpad in the XY direction. Under the action of frictional forces fx and fy, the touchpad is prevented from wobbling after assembly. However, in actual production, due to the individual differences of parts, it is difficult to guarantee 100% compression between the hot-melt pillars and the touchpad. Even if good compression is achieved, the touchpad will shift due to external forces during later handling. At the same time, the product will undergo thermal expansion and contraction when the environment changes, and gaps will still remain after hot-melt solidification, causing the touchpad to loosen as well. Summary of the Invention

[0005] To address at least the above-mentioned technical problems existing in the prior art, this application provides a hot-melt fixing structure, a touch panel, and an electronic product.

[0030] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] This application provides a thermofusion fixing structure, including a first connector, a second connector, a main thermofusion column, and an auxiliary thermofusion column. The first connector and the second connector need to be fixed by thermofusion. The main thermofusion column and the auxiliary thermofusion column are respectively provided on the two connectors. When the two are connected, they are fused together by the main thermofusion column and the auxiliary thermofusion column to achieve a stable connection between the first connector and the second connector.

[0032] The following description, in conjunction with the accompanying drawings, details the various structures of the thermoplastic fixing structure provided in the embodiments of this application, the positional relationships between the structures, and the connection relationships.

[0033] like Figures 1 to 4 As shown in the embodiment of this application, the main heat-melting column 13 is disposed on the first connector 11; the second connector 12 includes a connecting hole 121, and an auxiliary heat-melting column 14 is disposed on the edge of the connecting hole 121; when the first connector 11 and the second connector 12 are connected, if the first connector 11 and the second connector 12 are superimposed, the main heat-melting column 13 passes through the connecting hole 121, and the auxiliary heat-melting column 14 is located outside the main heat-melting column 13. The main heat-melting column 13 and the auxiliary heat-melting column 14 are subjected to heat-melting operation, and the two melt in a high-temperature environment and are flattened and fused into an integral structure, thereby realizing a stable connection between the first connector 11 and the second connector 12.

[0034] In this embodiment, a plurality of auxiliary heat-melting pillars 14 are provided on the second connector 12 at the edge of the connecting hole 121. During the heat-melting operation, the plurality of auxiliary heat-melting pillars 14 are fused together with the same main heat-melting pillar 13, which can further improve the stability of the connection between the first connector 11 and the second connector 12.

[0035] For example, multiple auxiliary heat fusion pillars 14 are evenly and spaced along the edge of the connecting hole 121. Multiple evenly arranged auxiliary heat fusion pillars 14 are arranged around the main heat fusion pillar 13. During the connection operation, the main heat fusion pillar 13 and the multiple auxiliary heat fusion pillars 14 can be fused together in all directions, ensuring the stability of the connection.

[0036] For example, the outer wall of the main hot melt column 13 is provided with a plurality of limiting protrusions 131; the plurality of limiting protrusions 131 are arranged at intervals along the circumference of the outer wall of the main hot melt column 13 and are used to pass through the interval between two adjacent auxiliary hot melt columns 14.

[0037] When the main hot melt column 13 is connected to the auxiliary hot melt column 14, the limiting protrusion 131 is engaged in the interval between two adjacent auxiliary hot melt columns 14. This connection method can ensure that the main hot melt column 13 and the auxiliary hot melt column 14 are connected in the correct position and have a larger contact area. During fusion, it can further ensure the stability of the connection between the main hot melt column 13 and the auxiliary hot melt column 14.

[0038] Continue to refer to Figure 1As shown in the embodiment of this application, the surface of the second connector 12 also has a hot melt groove 122; the connecting hole 121 is provided at the bottom of the hot melt groove 122, and the center of the connecting hole 121 coincides with the center of the hot melt groove 122.

[0039] After the main hot melt column 13 and the auxiliary hot melt column 14 are hot melted, their height will decrease and their unfolded area will increase. Therefore, after the hot melt groove 122 is provided on the surface of the second connector 12, the fused structure after hot melting is located in the hot melt groove 122. The hot melt groove 122 has a certain depth. The fused structure after hot melting is located in the hot melt groove 122, and its protruding height will decrease. In addition, the hot melt groove 122 will also limit the fused structure after hot melting.

[0040] For example, the diameter of the fused structure after hot melting is 6 millimeters.

[0041] like Figure 2 As shown in the embodiment of this application, when the main hot melt column 13 passes through the connecting hole 121, the height of the main hot melt column 13 is higher than the height of the auxiliary hot melt column 14; during hot melting, the main hot melt column 13 melts and comes into contact with the auxiliary hot melt column 14, and then the auxiliary hot melt column 14 melts and finally fuses together.

[0042] For example, the height difference between the ends of the main heat-melting column 13 and the auxiliary heat-melting column 14 is 0.2 mm to 0.4 mm, such as the height of the main heat-melting column 13 being 1.5 mm and the height of the auxiliary heat-melting column 14 being 1.2 mm.

[0043] like Figure 5 As shown, the hot-melt fixing structure 10 provided in this application embodiment utilizes the fusion of the main hot-melt column 13 and the auxiliary hot-melt column 14. When the two are hot-melted, there is more adhesive, and the diameter of the fused structure after hot-melting is larger. It has higher adhesive force along the direction perpendicular to the first connector 11 and the second connector 12, that is, the Z direction, to ensure the stability of the connection after hot-melting.

[0044] Furthermore, the fused structure after hot melting can generate tensile force in the horizontal direction. Under the tensile force of the fused structure after hot melting, the first connector 11 and the second connector 12 are fused into a stable whole. That is, after the first connector 11 and the second connector 12 are connected, they will not undergo any relative displacement during subsequent use or transportation and turnover, thus having higher stability.

[0045] When the first connector 11 and the second connector 12 need to be disassembled for maintenance, the fused structure is separated by external force. Even after separation, some fused structure will remain on the second connector 12; that is, some fused structure (irregular auxiliary fused pillars 14) will still be present on the second connector 12. After replacing the second connector 12 and the main fused pillar 13, the second connector 12 can continue to be used. After fusion, the main fused pillar 13 and the auxiliary fused pillar 14 remain fused together. This simplifies the maintenance of the first connector 11 and the second connector 12 and saves on investment costs.

[0046] like Figure 6 and Figure 7 As shown, this application embodiment provides a touch panel including the above-mentioned hot-melt fixing structure 10; the first connector 11 includes a frame 20, and the main hot-melt column 13 is disposed on the frame 20; the second connector 12 includes a housing 30, and the connecting hole 121 and the auxiliary hot-melt column 14 are disposed on the housing 30.

[0047] In the touchpad structure, the first connector 11 is a frame 20, and the second connector 12 is a housing 30. After the frame 20 is connected to a structure such as a circuit board, it is then fixedly connected by the main hot-melt post 13 and the auxiliary hot-melt post 14. Compared with traditional connection methods, such as screw connection, more parts are required, and to improve the stability of the connection, more structural parts need to be added. Therefore, problems such as complex product assembly and large size will occur. The hot-melt fixing structure 10 provided in this application embodiment has better connection stability, and can reduce the number of structural parts under the premise of stable structural connection.

[0048] For example, the housing 30 includes an operation window 31, the edge of which is provided with a reinforcing crossbeam 32 connected to the housing 30; a connection hole 121 and an auxiliary heat-fusion column 14 are provided on the reinforcing crossbeam 32. The reinforcing crossbeam 32 is used to provide the connection hole 121 and the auxiliary heat-fusion column 14. This part of the structure is integrally formed with the housing 30, which can ensure the connection strength of the touch panel control area, eliminating the need for or reducing the need for reinforcing ribs and other structures on the housing 30, thereby reducing the possibility of accidental touches on the touch panel.

[0049] In this embodiment, the shell 30 and the frame 20 can be stably connected under the action of the main hot melt column 13 and the auxiliary hot melt column 14. In order to further improve the stability of the connection between the two structures, a pull-out adhesive layer is provided between the reinforcing beam 32 and the frame 20. The pull-out adhesive layer connects the shell 30 and the frame 20, further improving the connection strength between the two.

[0050] Strengthening the structure of the crossbeam 32 can avoid problems such as movement and misalignment or even key jamming caused by the loosening of the original solution. It also effectively improves the strength of the touchpad and is suitable for the plastic shell 30 structure. Since the hot-melt fixing structure 10 has good stability, no additional control is required, thereby effectively reducing costs.

[0051] This application provides an electronic product that includes the above-described hot-melt fixing structure 10 or the above-described touch panel.

[0052] Taking a laptop computer as an example, a touchpad is installed on the system side of the laptop computer below the keyboard. The touchpad is formed by a hot-melt fixing structure 10.

[0053] This application provides a hot-melt fixing structure 10, a touch panel, and an electronic product. A main hot-melt column 13 and an auxiliary hot-melt column 14 are respectively provided on the first connector 11 and the second connector 12. During hot-melt welding, the main hot-melt column 13 and the auxiliary hot-melt column 14 are simultaneously welded together, fusing them into one unit. The technical solution of this application provides sufficient adhesive during hot-melt welding, resulting in a larger structural area and a more stable connection, especially with greater adhesion in the vertical direction. Furthermore, the fusion of the main hot-melt column 13 and the auxiliary hot-melt column 14 into one unit allows the first connector 11 and the second connector 12 to form a single integrated structure, resulting in higher connection stability. When disassembly is required, the auxiliary hot-melt column 14 can be hot-melted again without replacement, reducing the difficulty and cost of maintenance.
