TECHNICAL FIELD
[0001] The present application relates to a notebook computer, and particularly relates to a notebook computer with screwless fasteners. BACKGROUND
[0002] The structure of a notebook computer, such as a housing, a frame or a cover, discloses a composite structure using snaps and screws to achieve the effect of assembling and fixing together. In order to achieve structural strength or stability after assembly, the number of snaps and screws is only more or less, which leads to the appearance of the notebook computer not easy to be simple, and also causes the disassembly process to be complicated, and even the risk of tooth falling out, loss, etc. due to too many accessories such as screws.
[0003] ESG is the abbreviation of three English words, which are Environment, Social and Governance. The concept of ESG was first proposed by the United Nations Global Compact in 2004, and is regarded as an indicator for evaluating the operation of a company. ESG is a sustainable development indicator for a company, that is, carbon reduction and sustainable development goals. For the electronics manufacturing industry, whether the products manufactured can meet the above conditions becomes one of the evaluation conditions for the products.
[0004] In order to achieve the above-mentioned goals, the above-mentioned locking mechanism of the notebook computer needs corresponding new technologies and measures. Accordingly, how to modularize the components and be able to quickly assemble or disassemble has become the goal of the relevant technical personnel. SUMMARY
[0005] The present application provides a notebook computer with screwless fasteners, which has the effect of quick and convenient disassembly through the mutual pressing of the fasteners, so as to achieve the effect of screwless assembly.
[0006] The notebook computer with screwless fasteners of the present application comprises a first housing and a second housing. The first housing has a first plane and a first fastener extending from the first plane. The first fastener is inclined with respect to the first plane and is spirally arranged with respect to a central axis. The second housing has a second plane and a second fastener extending from the second plane. The second fastener is inclined with respect to the second plane and is spirally arranged with respect to the central axis. The first plane is parallel to the second plane, and the central axis is perpendicular to the first plane and the second plane. The first fastener and the second fastener are pressed against each other to fix the first housing and the second housing together.
[0007] Based on the above, the first fastener on the first housing is inclined relative to a first plane of the first housing and also helically arranged relative to the central axis, and the second fastener on the second housing is inclined relative to a second plane of the second housing and also helically arranged relative to the central axis. In this way, the first housing and the second housing can be assembled and fixed together by the interference effect of the first fastener and the second fastener being considered as helical hook structures that can be adapted to each other, without the need for additional accessories or tools. This effectively simplifies the assembly process of the notebook computer, and effectively avoids the above-mentioned situations such as screw tooth falling out or missing due to the screwless assembly method. The notebook computer can thus reduce the number of components and manufacturing costs, and thus has better space utilization. BRIEF DESCRIPTION OF DRAWINGS

[0037] Figure 1 is an exploded view of a notebook computer according to an embodiment of the present application. Figure 2A and Figure 2B are respectively Figure 1 partial structural schematic views of a notebook computer. Please refer to Figure 1 , Figure 2A and Figure 2B , in this embodiment, the notebook computer 100 comprises a first housing 110 and a second housing 120 assembled together, here is taken as an example of the system host shell, but the embodiment is not limited thereto. That is, as described above, for the notebook computer 100 related structure such as shell, frame or cover, which needs to be assembled with each other, can be applied to the subsequent features of the embodiment.
[0038] Figure 3 is Figure 2A and Figure 2B structural combination schematic view. Please refer to Figure 2A , Figure 2B and Figure 3 , it should be pointed out that in order to obtain better appearance recognition effect, here will be Figure 1The first shell 110 and the second shell 120 are simplified. In this embodiment, the first shell 110 has a first plane S1 and a first fastener extending from the first plane S1. Here, the first fastener includes a pair of vertical wall structures, and is divided into vertical wall one 111 and vertical wall two 112. The first fastener is inclined relative to the first plane S1 and is spirally arranged relative to the central axis RX. The second shell 120 has a second plane S2 and a second fastener extending from the second plane S2. Here, the second fastener includes another pair of vertical wall structures, and is divided into vertical wall three 121 and vertical wall four 122. The second fastener is inclined relative to the second plane S2 and is spirally arranged relative to the central axis RX.
[0039] like Figure 3 As shown, for the assembled first shell 110 and the second shell 120, the first plane S1 is parallel to the second plane S2, and the central axis RX is perpendicular to the first plane S1 and the second plane S2. The first fastener and the second fastener are interlaced and tightened to fix the first shell 110 and the second shell 120 together. It should be noted that in order to improve Figure 3 To improve the recognition rate of related components, a perspective drawing is provided for the first fastener and the second fastener, and the hidden lines are also drawn with different line types. The first fastener is drawn with a two-point chain line, and the second fastener is drawn with a dotted line. If the related label points to the hidden surface of the structure, the corresponding label line is also drawn with the hidden line of the structure.
[0040] like Figure 2A As shown, in this embodiment, a first virtual axis AX is located on the first plane S1. The first vertical wall 111 and the second vertical wall 112 are located on the first virtual axis AX. The central axis RX passes through the first virtual axis AX and is located between the first vertical wall 111 and the second vertical wall 112. The first virtual axis AX divides the first plane S1 into two areas. The first vertical wall 111 and the second vertical wall 112 are respectively inclined toward the two areas and are spirally inclined relative to the central axis RX. In short, as Figure 2A As shown, the vertical wall 111 and the vertical wall 2 112 can be regarded as gradually extending upward (away from the first plane S1) with the bottom surface as the reference, wherein the bottom surface is located on the first plane S1 and on the first virtual axis AX, and the structures of the vertical wall 111 and the vertical wall 2 112 are inclined, extended and twisted in a specific direction. In this embodiment, the specific direction is Figure 2A The spiral direction RD is shown in .
[0041] like Figure 2B As shown, in this embodiment, there is a second virtual axis BX on the second plane S2, which divides the second plane S2 into two areas, and the third vertical wall 121 and the fourth vertical wall 122 are respectively located in the two areas and are both spirally inclined toward the second virtual axis BX. The central axis RX passes through the second virtual axis BX and is located between the third vertical wall 121 and the fourth vertical wall 122.Figure 2A Similarly, the third vertical wall 121 and the fourth vertical wall 122 are gradually extended upward based on the bottom surface located on the second plane S2, and their structures are also inclined, extended and twisted in a specific direction (helical direction RD). Figure 2A In contrast, both the first and second fasteners are twisted in the same spiral direction RD relative to the central axis RX. In other words, their structural extension paths are both spiral, differing only in the position of their bottom surfaces. With the central axis RX as the reference, the difference between the first virtual axis AX and the second virtual axis BX is equivalent to a rotation of the aforementioned spiral path by an angle. That is, the orthographic projection of the first virtual axis AX on the second plane S2 is rotated by an angle relative to the second virtual axis BX, and vice versa. This rotation can be achieved by treating the central axis RX as the center of the circle, and causing the first and second fasteners to perform circular motion relative to the center of the circle.
[0042] Figure 4 This is a diagram of the combination of the first fastener and the second fastener. Please refer to Figure 3 and Figure 4 , and compare Figure 2A In this embodiment, the first fastener and the second fastener have a plurality of contact surfaces corresponding to each other one to one, wherein the vertical wall 111 has a first contact surface 111a, which is spirally inclined toward one of the two different areas separated by the first virtual axis AX, and the vertical wall 112 has a second contact surface 112a, which is spirally inclined toward the other of the two different areas. Please refer to Figure 3 and Figure 4 , and compare Figure 2B The third vertical wall 121 has a third abutting surface 121a that is spirally inclined toward the second virtual axis BX, and the fourth vertical wall 122 has a fourth abutting surface 122a that is spirally inclined toward the second virtual axis BX. When the first housing 110 and the second housing 120 are assembled together, the first abutting surface 111a abuts the fourth abutting surface 122a, and the second abutting surface 112a abuts the third abutting surface 121a.
[0043] Figure 4 Equivalent to Figure 3Observing the relevant components from top to bottom, taking the vertical wall 3 121 and the vertical wall 4 122 as examples, the third abutting surface 121a includes a part A1 and a part A2, and the fourth abutting surface 122a includes a part B1 and a part B2, wherein the first abutting surface 111a abuts against the part B2 of the fourth abutting surface 122a, thereby exposing the part B1. On the other hand, the second abutting surface 112a abuts against the part A2 of the third abutting surface 121a, thereby exposing the part A1. Because the vertical wall 1 111, the vertical wall 2 112, the vertical wall 3 121 and the vertical wall 4 122 all generate structural inclination, extension and twisting along the spiral direction RD based on the central axis RX, when the first fastener ( Figure 4 The top diagram shows the vertical wall 111 and the vertical wall 2 112) and the second fastener ( Figure 4 In the middle diagram, when the vertical wall 3 121 and the vertical wall 4 122 are close to each other and combined along the central axis RX, the abutting surfaces of the fasteners abut each other as described above. If the vertical wall 111 and the vertical wall 2 112 are used as references, the vertical wall 3 121 and the vertical wall 4 122 are located on opposite sides of the vertical wall 111 and the vertical wall 2 112, and the clamping force generated by the abutment will cause planar interference of the components (the planar interference refers to the plane with the central axis RX as the normal). At the same time, Figure 3 As shown, each of these abutment surfaces is also inclined relative to the central axis RX, that is, Figure 3 In the height direction (that is, in the direction along the central axis RX), these abutting surfaces will also produce component interference. In this way, the first fastener and the second fastener can produce a three-dimensional spatial interference (limiting) effect due to the mutual corresponding tension of these abutting surfaces.
[0044] Furthermore, the clamping force of the first and second fasteners increases as the contact area between the first abutting surface 111a and the fourth abutting surface 122a increases, and also increases as the contact area between the second abutting surface 112a and the third abutting surface 121a increases. In other words, the larger the contact area of the abutting surfaces, the stronger the component interference strength generated will be (if the first and second fasteners are regarded as hooks, this also means that the amount of engagement between the first and second fasteners will increase). In addition, the contact area between the first abutting surface 111a and the fourth abutting surface 122a and the contact area between the second abutting surface 112a and the third abutting surface 121a increase as the first plane S1 and the second plane S2 approach, respectively. Accordingly, the designer can appropriately adjust the interference effect by setting the abutting surfaces and the height of the vertical wall protruding from the plane, so as to achieve the required structural strength and stability after the first shell 110 and the second shell 120 are combined.
[0045] Figure 5A FIG. 1 is a schematic diagram of the first fastener and the second fastener before being combined. Figure 5B yes Figure 5APlease also refer to the partial cross-sectional view of Figure 5A and Figure 5B ,in Figure 5B yes Figure 5A Bottom view along the A-A' section line. Figure 5B Taking the second vertical wall 112 and the third vertical wall 121 on the right side of the middle as an example (the first vertical wall 111 and the fourth vertical wall 122 on the left side also present the same situation and will not be repeated here), the ranges OP1 and OP2 shown represent the overlapping ranges of the two after they are docked and assembled, that is, equivalent to the range of torsional deformation that will occur between the second vertical wall 112 and the third vertical wall 121 after docking. The fact that the range OP1 is smaller than the range OP2 can also be used to see the torsional direction of the structural interference. Here, the ranges OP1 and OP2 are equivalent to the inner and outer arcs of the circular motion generated with the central axis RX as the center, which conforms to the structural design of the second vertical wall 112 and the third vertical wall 121 (that is, the spiral inclination of the second abutting surface 112a and the third abutting surface 121a), thereby ensuring the deformation of the vertical wall after docking, thereby preventing the first fastener and the second fastener from being too much engaged and causing damage or breakage.
[0046] On the other hand, please refer to Figure 2A and Figure 2B To facilitate the mating of the first and second fasteners, vertical wall 111 of this embodiment further includes a first guide surface 111b, and vertical wall 2 112 further includes a second guide surface 112b. These first and second guide surfaces 111b and 112b are inclined relative to first plane S1. Correspondingly, vertical wall 3 121 includes a third guide surface 121b, and vertical wall 4 122 includes a fourth guide surface 122b. These third and fourth guide surfaces 121b and 122b are inclined relative to second plane S2. During the assembly process of the first shell 110 and the second shell 120, the vertical wall 111 and the vertical wall 4 122 are guided by the contact between the first guide surface 111b and the fourth guide surface 122b, and the vertical wall 2 112 and the vertical wall 3 121 are guided by the contact between the second guide surface 112b and the third guide surface 121b, so as to facilitate the first fastener and the second fastener to approach each other but before the abutting surfaces contact, thereby avoiding interference along the center axis RX through the above guidance.
[0047] In the above-mentioned embodiments of the present application, the first fastener on the first casing is inclined with respect to the first plane of the first casing and also with respect to the central axis, and the second fastener on the second casing is inclined with respect to the second plane of the second casing and also with respect to the central axis. The structures of the first fastener, the first and second vertical walls, have their bottom surfaces lying on the first plane and gradually extending out, and are inclined, extended and twisted with respect to the first plane based on the central axis. The structures of the second fastener, the third and fourth vertical walls, have their bottom surfaces lying on the second plane and gradually extending out, and are inclined, extended and twisted with respect to the second plane based on the central axis.
[0048] Accordingly, the abutment of the first fastener and the second fastener with each other means that the vertical walls abut with each other, and the first casing and the second casing can be assembled and fixed together by the interference of the first fastener and the second fastener, so that the first fastener and the second fastener can be considered as mutually adaptable screw-type hook structures, thereby generating a three-dimensional interference effect. This effectively simplifies the assembly process of the notebook computer, and effectively avoids the screw tooth falling out or being lost, etc. due to the screwless assembly method. The notebook computer can thus reduce the number of components and manufacturing costs, and has better space utilization.
