Description

Technical Field

[0001] This invention relates to an electronic device and its fastening assembly, and more particularly to an electronic device and its fastening assembly that can fasten and fix two housings together. Background Technology

[0002] Currently, flip-style electronic products (such as laptops or tablets with detachable keyboards) use pivot mechanisms or snap-fit ​​mechanisms to secure the upper and lower casings together. Some snap-fit ​​mechanisms pivot one end to the upper or lower casing, and rotating the mechanism engages the other end with the corresponding locking structure on the upper or lower casing. However, if the distance between the upper and lower casings changes, the snap-fit ​​mechanism cannot accurately align with the locking structure. Summary of the Invention

[0003] In view of this, in one embodiment, an electronic device is provided, including a first housing, a second housing, and a fastening assembly. The first housing includes a first fixing surface with a fastening portion. The second housing includes a second fixing surface and two receiving grooves, each receiving groove being disposed on both sides of the second fixing surface. The fastening assembly includes a latching member and two elastic elements. The latching member has a hook portion and two fixing rods, the two fixing rods being disposed on both sides of the hook portion, and one end of each fixing rod abutting against the second fixing surface and sliding relative to the second fixing surface, while the other end extends into the corresponding receiving groove. The hook portion is used to fasten to the fastening portion. Each elastic element is respectively received in the receiving groove, and one end of each elastic element is connected to the second housing, and the other end is connected to the fixing rod.

[0004] In one embodiment, each fixing rod has an arc-shaped surface that abuts against the second fixing surface, and the center of the arc-shaped surface is far away from the fixing rod.

[0005] In one embodiment, the hook portion can be moved to a first position, a second position, or a third position. When the hook portion slides from the first position to the third position, the hook portion deflects to the second position along the center of the arc surface, and when the hook portion is in the third position, the hook portion engages with the engaging portion.

[0006] In one embodiment, the hook portion has a guide surface. When the hook portion moves from the first position to the second position, the guide surface contacts the fastening portion, causing the fastener to be guided by the guide surface and deflected to the second position.

[0007] In one embodiment, when the hook portion is in the second position, the top end of the hook portion is a first distance from the first fixing surface, and the top end of the fastening portion is a second distance from the first fixing surface. The first distance is essentially equal to the second distance.

[0008] In one embodiment, the fastener includes a first baffle extending to a second fixing surface. The first baffle has a first contact surface. The second fixing surface includes a second baffle with a second contact surface. When the hook is in a first position or a third position, the first contact surface and the second contact surface are separated. When the hook is in a second position, the first contact surface contacts the second contact surface.

[0009] In one embodiment, the second fixing surface includes a limiting groove located between the second baffle and the receiving groove, and the fastener includes a third baffle extending into the limiting groove.

[0010] In one embodiment, each receiving slot has a retaining wall, and each fixing rod has a first inclined surface and a second inclined surface relative to one side of the arc-shaped surface. When the hook part is in the first position and the second position, the first inclined surface contacts and slides on the retaining wall, and when the hook part is in the second position, the second inclined surface contacts and slides on the retaining wall.

[0011] In one embodiment, each retaining wall forms an opening with the second fixed surface, and each fixed rod slides in each opening.

[0012] In one embodiment, the fastener further includes an operating part located on one side of the center of the arcuate surface, and a hook part located on the other side of the center of the arcuate surface. When the operating part is actuated, the fastener moves from the first position to the second position or the third position.

[0013] In one embodiment, the first fixing surface includes another fastening portion, and the hook portion fastens to one of the fastening portions and the other fastening portion.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Attached Figure Description

[0061] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0062] Please see Figures 1 to 4 . Figure 1 This is a perspective view of the electronic device in the first embodiment of the present invention. Figure 2 for Figure 1 A front view of a portion of the electronic device within the selected area. Figure 3 for Figure 1 A bottom view of a portion of the electronic device within the selected area. Figure 4 This is a partial side view of the electronic device in the first embodiment of the present invention, showing the center of the latching member and the arcuate surface. Figures 1 to 4As shown, in this embodiment, the electronic device 10 includes a first housing 101, a second housing 103, and a fastening assembly 105. The first housing 101 includes a first fixing surface 107, which has a fastening portion 109. The second housing 103 includes a second fixing surface 111 and two receiving grooves (113, 113'), which are respectively disposed on both sides of the second fixing surface 111. The fastening assembly 105 includes a latching member 115 and two elastic elements (117, 117'). The latching member 115 has a hook portion 119 and two fixing rods (121, 121'), which are disposed on both sides of the hook portion 119. Figure 3 As can be seen, one end of each fixing rod (121, 121') abuts against the second fixing surface 111 and slides relative to the second fixing surface 111, while the other end extends into the corresponding receiving groove (113, 113'). The hook part 119 is used to fasten to the fastening part 109. Figure 2 and Figure 3 As can be seen, the two elastic elements (117, 117') are respectively housed in the two receiving grooves (113, 113'), and one end of each elastic element (117, 117') is connected to the second housing 103, and the other end is connected to the fixing rod (121, 121').

[0063] Please see Figure 4 ,exist Figure 4 The example only uses one side of the fixing rod 121 as an example; the fixing rod 121' on the other side also has a corresponding structure. In this embodiment, each fixing rod (121, 121') has an arc-shaped surface 123, which abuts against the second fixing surface 111, and the center C formed by the arc-shaped surface 123 is far away from the fixing rod (121, 121') (details to follow).

[0064] For example Figure 1As shown, the electronic device 10 can be a clamshell electronic product (such as a laptop or a tablet computer with a detachable keyboard). For example, if the electronic device 10 is a laptop, the first housing 101 can be either a screen or a keyboard, and the second housing 103 can be either a screen or a keyboard. If the electronic device 10 is a tablet computer with a detachable keyboard, the first housing 101 can be either a tablet computer or a detachable keyboard, and the second housing 103 can be either a tablet computer or a detachable keyboard. Any electronic device 10 having a first housing 101 and a second housing 103, and where the first housing 101 and the second housing 103 can be opened and closed relative to each other, can be implemented, and is not limited thereto. Furthermore, when the first housing 101 and the second housing 103 are abutted against each other, the first fixing surface 107 is adjacent to the second fixing surface 111. The first fixing surface 107 can be substantially parallel to the second fixing surface 111, allowing the latching member 115 to easily slide on the second fixing surface 111 and engage with the latching portion 109 of the first fixing surface 107.

[0065] For example Figure 2 and Figure 3 As shown, the two receiving slots (113, 113') can be disposed adjacent to both sides of the second fixing surface 111, and both sides of the second fixing surface 111 are respectively connected to the two receiving slots (113, 113'), so that when the fastener 115 abuts against the second fixing surface 111, the two fixing rods (121, 121') can extend into the corresponding receiving slots (113, 113') through the second fixing surface 111. Furthermore, two elastic elements (117, 117') can be respectively disposed in the corresponding receiving slots (113, 113'), and one end of each elastic element (117, 117') can be locked or welded to the second housing 103. The other end of each elastic element (117, 117') can be hooked onto the corresponding fixing rod (121, 121'). Specifically, by Figure 2 As can be seen, each fixing rod (121, 121') has a snap hole 124, and the other end of each elastic element (117, 117') can be hooked into the snap hole 124 respectively, so that the two elastic elements (117, 117') can pull the two fixing rods (121, 121') respectively by their own elastic force under normal conditions, and so that when the buckle 115 slides relative to the second fixing surface 111, the buckle 115 can slide against the second fixing surface 111. The elastic elements (117, 117') can be, for example, springs or elastic ropes.

[0066] For example Figure 3 and Figure 4 As shown, it should be noted first that in Figure 4 Taking fixed rod 121 as an example, fixed rod 121' is the same as fixed rod 121, so it will not be described again. Figure 4The two elastic elements (117, 117') are omitted. In this embodiment, the receiving grooves (113, 113') each have retaining walls (125, 125'), and each fixing rod (121, 121') has a first inclined surface 127 and a second inclined surface 129 on the side opposite to the arc-shaped surface 123. Each retaining wall (125, 125') and the second fixing surface 111 respectively form an opening (131, 131'), and each fixing rod (121, 121') slides within the two openings (131, 131'). When each fixing rod (121, 121') slides relative to the second fixing surface 111, the first inclined surface 127 and the second inclined surface 129 can respectively contact and slide on the retaining walls (125, 125') (described later).

[0067] Please refer to the following: Figures 5 to 8 . Figure 5 This is a schematic diagram showing the positions of the hook and the fastening part when the hook part is in the first position in the first embodiment of the present invention. Figure 6 This is a schematic diagram showing the positions of the hook and the fastening part when the hook and fastening part are between the first and second positions in the first embodiment of the present invention. Figure 7 This refers to the positional relationship between the hook and the fastening part when the hook part is in the second position in the first embodiment of the present invention. Figure 8 This describes the positional relationship between the hook and the fastening part when the hook part is in the third position in the first embodiment of the present invention. Figures 5 to 8 Taking the fixing rod 121 on one side as an example, the operation and structure of the fixing rod 121' on the other side are the same as those of the fixing rod 121. The following description of the fixing rod 121' will refer to the fixing rod 121. In this embodiment, as Figures 5 to 8 As shown, the hook part 119 can be moved to a first position P1, a second position P2, or a third position P3. When the hook part 119 slides from the first position P1 to the third position P3, the hook part 119 deflects along the center C of the arc surface 123 to the second position P2 (explained later), and when the hook part 119 is in the third position P3, the hook part 119 is engaged with the fastening part 109.

[0068] like Figure 5 As shown, when the buckle 115 is not activated, the fixing rod 121 is pulled by the elastic element 117, so that the hook part 119 is normally held in the first position P1. The arc-shaped surface 123 of the fixing rod 121 abuts against the second fixing surface 111.

[0069] like Figure 5 and Figure 6As shown, when the latching member 115 is actuated, causing the hook portion 119 to move from the first position P1 to the second position P2, the fixing rod 121 is initially still under the traction of the elastic element 117, and at this moment, the arc-shaped surface 123 of the fixing rod 121 slides on the second fixing surface 111. When the latching member 115 is continuously actuated, and the hook portion 119 abuts against the engaging portion 109 until... Figure 6 As shown, the hook portion 119 can be deflected to the second position P2 along the center C of the arc-shaped surface 123 (as shown). Figure 7 (As shown). When the hook part 119 is between the first position P1 and the second position P2, the first inclined surface 127 contacts and slides on the retaining wall 125. Specifically, the hook part 119 has a guide surface 133. When the hook part 119 moves from the first position P1 to the second position P2, the guide surface 133 contacts the fastening part 109, so that the fastener 115 is guided by the guide surface 133 and deflects to the second position P2 along the center C of the arc surface 123.

[0070] like Figure 7 As shown, when the hook part 119 is in the second position P2, the top end 119a of the hook part 119 is a first distance D1 from the first fixing surface 107, and the top end 109a of the fastening part 109 is a second distance D2 from the first fixing surface 107. At this time, the first distance D1 is essentially equal to the second distance D2. That is to say, when the hook part 119 deflects along the center C of the arc surface 123 to the fastening part 109, the hook part 119 can move along the fastening part 109 from the second position P2 to the third position P3 (e.g., ...). Figure 8 (As shown). Furthermore, when the hook part 119 is in the second position P2, the arc-shaped surface 123 of the fixing rod 121 is away from the second fixing surface 111, while the second inclined surface 129 contacts and slides on the retaining wall 125, so that the fixing rod 121 can slide on the retaining wall 125 through the second inclined surface 129.

[0071] like Figure 8 As shown, when the hook part 119 is in the third position P3, the hook part 119 is engaged with the fastening part 109. It should be noted that to return the hook part 119 from the third position P3 to the first position P1, the latching member 115 can be actuated again, allowing the fixing rod 121 to rotate relative to the second fixing surface 111 using the arc-shaped surface 123 as a fulcrum, thus separating the hook part 119 from the fastening part 109. Furthermore, when the hook part 119 moves along the fastening part 109 from the third position P3 to the second position P2, the hook part 119 can move along the fastening part 109 again. And when the hook part 119 continues to move from the second position P2 to the first position P1, the fixing rod 121 is pulled by the elastic element 117, causing the hook part 119 to return from the second position P2 to the first position P1, at which point the arc-shaped surface 123 again abuts against the second fixing surface 111.

[0072] For example Figure 2 As shown, in this embodiment, the latching member 115 further includes an operating part 135. The arc-shaped surface 123 is located between the operating part 135 and the hook part 119. When the operating part 135 is actuated, the latching member 115 can move between a first position P1, a second position P2, and a third position P3. In this embodiment, actuating the operating part 135 can refer to... Figure 2 A force is applied to the operating part 135 in the Y-axis direction to push the latching member 115 to slide relative to the second fixed surface 111. This can also refer to... Figure 2 A force is applied to the operating part 135 in the negative direction of the Z-axis (i.e., pressing the operating part 135). In this embodiment, after the operating part 135 is actuated to rotate the buckle 115, the hook part 119 can first be deflected along the center C of the arc surface 123. When the hook part 119 moves from the first position P1 to the second position P2, the hook part 119 may or may not contact the fastening part 109 (i.e., the first distance D1 may be greater than or equal to the second distance D2). Then, it moves to the second position P2 and the third position P3, and the hook part 119 is fastened to the fastening part 109 in the third position P3.

[0073] Please refer to both together. Figure 1 and Figure 9 . Figure 9 for Figure 2 The cross-sectional view along direction AA shows the positional relationship between the first and second baffles when the hook is in the third position. For example... Figure 1 and Figure 9 As shown in the figure, in this embodiment, the latching member 115 further includes a first baffle 137 (see [reference needed]). Figure 3 and Figure 9 The first baffle 137 extends to the second fixing surface 111, and the first baffle 137 has a first contact surface 139. The second fixing surface 111 includes a second baffle 141 (see...). Figure 3 and Figure 9 The second baffle 141 has a second contact surface 143. When the hook part 119 is in the first position P1 or the third position P3, the first contact surface 139 separates from the second contact surface 143. When the hook part 119 is in the second position P2, the first contact surface 139 contacts the second contact surface 143. It should be noted that when the hook part 119 moves from the second position P2 to the first position P1 or the third position P3, the latching member 115 can slide on the second contact surface 143 of the second baffle 141 through the first contact surface 139 of the first baffle 137, so that the latching member 115 can slide more smoothly on the second fixed surface 111. For example... Figure 3As shown, the second fixing surface 111 further includes a limiting groove 145. The limiting groove 145 is located between the second baffle 141 and the receiving groove 113. The fastener 115 has third baffles (147, 147') on both sides, and the two third baffles (147, 147') extend into the limiting groove 145. Therefore, when the fastener 115 slides relative to the second fixing surface 111, the limiting groove 145 can restrain the third baffles (147, 147') in the horizontal direction (e.g., ...). Figure 3 The limiting action (in the X-axis direction) confines the two third baffles (147, 147') within the limiting groove 145. This allows the fastener 115 to reduce its position in the horizontal direction (e.g., in the X-axis direction). Figure 3 The offset in the X-axis direction makes the movement trajectory of the buckle 115 more stable.

[0074] Please merge Figures 1 to 10 . Figure 10 This is a partial perspective view of the electronic device in a second embodiment of the present invention. Figures 1 to 10 As shown, in this embodiment, the first fixing surface 107 further includes another fastening portion 149, and the hook portion 119 fastens to one of the fastening portion 109 and the other fastening portion 149. When the hook portion 119 is in the first position P1, the fastening portion 109 is closer to the hook portion 119 than the fastening portion 149. In other words, the distance between the hook portion 119 and the fastening portion 149 is greater than the distance between the hook portion 119 and the fastening portion 109. Accordingly, the latching member 115 can fasten the hook portion 119 to either the fastening portion 109 or the fastening portion 149 based on the distance between the first housing 101 and the second housing 103. For example, in the second embodiment, the electronic device 10 can be equipped with an external attachment (not shown in this figure), which can be, for example, a detachable handle. Because the external attachment has thickness, when the external attachment is installed on the first housing 101 or the second housing 103, the distance between the first housing 101 and the second housing 103 will increase. At this time, the hook part 119 cannot be fastened to the fastening part 149 which is farther away, and it is suitable to fasten the hook part 119 to the fastening part 109 which is closer. When the external attachment is not installed on the first housing 101 or the second housing 103, the distance between the first housing 101 and the second housing 103 does not change. At this time, the hook part 119 can be fastened to the fastening part 149, and it is suitable to fasten the hook part 119 to the fastening part 149.

[0075] In summary, in the electronic device 10 provided in one embodiment of the present invention, when the hook portion 119 slides from the first position P1 to the third position P3, the hook portion 119 deflects to the second position P2 (i.e., eccentric rotation) along the center C of the arc-shaped surface 123, so that when the hook portion 119 is in the third position P3, the hook portion 119 can be engaged with the engaging portion 109. This allows the first housing 101 and the second housing 103 to be engaged and fixed together.

[0076] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
