In addition to these detailed descriptions, the present utility model can also be widely implemented in other embodiments. Any easy substitution, modification, and equivalent change of any of the said embodiments are included within the scope of the present utility model and shall be subject to the subsequent patent scope. Furthermore, in the description of the specification, in order to enable the reader to have a more complete understanding of the present utility model, many specific details are provided; however, the present utility model may still be implemented on the premise of omitting some or all of these specific details. In addition, well - known common elements are not described in detail to avoid unnecessary limitations on the present utility model.

[0042] Please refer to Figure 1A and Figure 1B , Figure 1A which shows a schematic diagram of the snap - on device 100 of an embodiment of the present utility model in a released state, while Figure 1B shows a schematic diagram of the snap - on device 100 in a snapped - on state.

[0043] The fastening device 100 may include a base assembly 110 and a fastening assembly 120. The fastening assembly 120 may be disposed on the base assembly 110. The fastening assembly 120 may include a fastening body 121 and at least one rotating shaft member 122. In this embodiment, the number of the rotating shaft members 122 is taken as two as an example for illustration. Corresponding to the number of the rotating shaft members 122, the base assembly 110 has at least one groove G. That is, in this embodiment, the number of the grooves G is also two. Each rotating shaft member 122 is fixed to the fastening body 121 and disposed in a corresponding groove G. In this embodiment, the two rotating shaft members 122 are respectively disposed in the two grooves G on both sides of the base assembly 110. The fastening body 121 is movable relative to the base assembly 110 through the rotating shaft members 122. Specifically, the fastening body 121 is movable in the groove G of the base assembly 110. As Figure 1A shown in Figure 1B , corresponding to two different positions where the fastening body 121 moves in the groove G, the fastening assembly 120 can be switched between a release state and a fastening state.

[0044] Please further refer to Figure 2 , which shows a side view of the working mechanism of the fastening device 100 being switched between a release state and a fastening state. The following describes the working process in conjunction with Figure 2 shown content.

[0045] The groove G may have a first oriented groove portion G1 and a second oriented groove portion G2 that are connected and non-parallel to each other. In this embodiment, the first oriented groove portion G1 and the second oriented groove portion G2 are designed to be substantially perpendicular to each other. That is, the groove G formed by the first oriented groove portion G1 and the second oriented groove portion G2 is an L-shaped groove, where the first oriented groove portion G1 is a horizontal groove and the second oriented groove portion G2 is a vertical groove.

[0046] When the fastening assembly 120 is in the release state, the fastening assembly 120 is located in the first oriented groove portion G1. Specifically, the fastening body 121 is positioned at the rightmost end of the first oriented groove portion G1 through the rotating shaft members 122. First, the fastening assembly 120 can be horizontally moved to the left along the first oriented groove portion G1 to move to the leftmost end (also the uppermost end of the second oriented groove portion G2) of the first oriented groove portion G1. Next, the fastening assembly 120 can be rotated substantially 90 degrees along the axial direction of the rotating shaft members 122 at the uppermost end of the second oriented groove portion G2 (in terms of the Figure 2 drawing, rotate clockwise). Finally, the fastening assembly 120 can be vertically moved downward along the second oriented groove portion G2 to move to the lowermost end of the second oriented groove portion G2. Thus, the switching of the fastening assembly 120 from the release state to the fastening state can be completed.

[0047] When the fastening component 120 is in the fastened state, the fastening component 120 is located in the second guiding groove portion G2. If one wants to switch the fastening component 120 from the fastened state back to the released state, the fastening component 120 can first be vertically moved upward along the second guiding groove portion G2 to move to the uppermost end of the second guiding groove portion G2 (which is also the leftmost end of the first guiding groove portion G1). Then, the fastening component 120 can be substantially rotated 90 degrees counterclockwise (in terms of the drawing of Figure 2 ), along the axial direction of the rotating shaft member 122, at the uppermost end of the second guiding groove portion G2. Finally, the fastening component 120 can be horizontally moved to the right along the first guiding groove portion G1 to move to the rightmost end of the first guiding groove portion G1. Thus, the switching of the fastening component 120 from the fastened state back to the released state can be completed.

[0048] Please further refer to Figure 3A to 3C , Figure 3A a schematic diagram showing the base component 110 of the fastening device 100, Figure 3B an exploded view showing the base component 110, and Figure 3C a part drawing showing the base body 111 of the base component 110.

[0049] The base component 110 may include a base body 111, a first magnetic block member 112M1, a bottom plate layer member 113, and a magnetic sheet member 114M. The base body 111 may have a side receiving groove 111S, and the magnetic sheet member 114M may be disposed in the side receiving groove 111S. For example, the magnetic sheet member 114M may be attached to the wall surface of the side receiving groove 111S by adhesion, but is not limited thereto. Continuing from the previous context, when the fastening component 120 is in the released state, the fastening body 121 is positioned at the rightmost end of the first guiding groove portion G1, that is, adjacent to the magnetic sheet member 114M. At this time, the magnetic sheet member 114M disposed in the side receiving groove 111S can be used to provide a magnetic attraction force to attract a magnetic element (to be described later) in the fastening component 120, thereby strengthening the positioning of the fastening component 120 in the first guiding groove portion G1.

[0050] The base body 111 may have a first bottom receiving groove 111B1, and the first magnetic block 112M1 may be disposed in the first bottom receiving groove 111B1. The bottom plate layer 113 may be fixed to the bottom of the base body 111 to cover the first bottom receiving groove 111B1, thereby enclosing the first magnetic block 112M1 inside the base body 111. For example, the bottom plate layer 113 may be, but is not limited to, a double-sided adhesive layer, and is adhered to the outer frame around the first bottom receiving groove 111B1 at the bottom of the base body 111 by adhesion. Continuing from the previous premise, when the fastening assembly 120 is in the fastened state, the fastening body 121 is positioned at the lowermost end of the second guiding groove portion G2, that is, adjacent to the first magnetic block 112M1. At this time, the first magnetic block 112M1 disposed in the first bottom receiving groove 111B1 can provide a magnetic attraction force through the base body 111 to attract a magnetic element (to be described later) in the fastening assembly 120, thereby strengthening the positioning of the fastening assembly 120 in the second guiding groove portion G2.

[0051] Please further refer to Figure 4A to 4B , Figure 4A a schematic diagram showing the fastening assembly 120 of the fastening device 100, and Figure 4B an exploded view showing the fastening assembly 120 of the fastening device 100.

[0052] The fastening assembly 120 may further include a second magnetic block 123M2. The fastening body 121 may have a second bottom receiving groove 121B2, and the second magnetic block 123M2 may be disposed in the second bottom receiving groove 121B2. Continuing from the previous description, when the fastening assembly 120 is in the released state, the magnetic sheet 114M disposed in the side receiving groove 111S can be used to provide a magnetic attraction force to attract the second magnetic block 123M2 in the fastening assembly 120; when the fastening assembly 120 is in the fastened state, the first magnetic block 112M1 disposed in the first bottom receiving groove 111B1 can provide a magnetic attraction force through the base body 111 to attract the second magnetic block 123M2 in the fastening assembly 120. Through the magnetic attraction force design, the positioning of the fastening assembly 120 in the first guiding groove portion G1 or the second guiding groove portion G2 in the released state or the fastened state can be strengthened.

[0053] Corresponding to the number of the rotating shaft members 122, the fastening body 121 may have at least one shaft hole H. That is, in this embodiment, the number of the shaft holes H is also two, which are respectively arranged on opposite sides of the fastening body 121. The two rotating shaft members 122 are respectively inserted through the two shaft holes H. The two rotating shaft members 122 are arranged in the two shaft holes H to form a coaxial line, so as to provide the fastening body 121 to rotate along this coaxial line in the groove G. In addition, the two rotating shaft members 122 are inserted through the shaft holes H to enter the second bottom receiving groove 121B2 to fix the second magnetic block member 123M2. Specifically, the rotating shaft member 122 may have a connected thick shaft portion 122TK and a thin shaft portion 122TN. A part of the thin shaft portion 122TN is inserted through the shaft hole H to enter the second bottom receiving groove 121B2 and fix the second magnetic block member 123M2. The other part of the thin shaft portion 122TN and the thick shaft portion 122TK are exposed outside the fastening body 121. As Figure 4A shown, the other part of the exposed thin shaft portion 122TN and the thick shaft portion 122TK may be located in the groove G during assembly to guide the movement or rotation of the fastening body 121 in the groove G.

[0054] Please further refer to Figure 5A to 5C , Figure 5A which shows a schematic diagram of the housing assembly 1 according to an embodiment of the present invention, Figure 5B shows a magnified view of a partial area A1 of the housing assembly 1 in Figure 5A , Figure 5C and shows a magnified view of the fastening assembly 120 of the housing assembly 1 in a fastened state.

[0055] The housing assembly 1 is, for example, a housing assembly of a notebook computer, and may include a housing body 10 and a fastening device 100. The housing body 10 may include a battery module 11. The fastening device 100 may be arranged on the housing body 10. Specifically, the fastening device 100 may be fixed to the housing body 10 through a bottom plate layer member 113. When the bottom plate layer member 113 is implemented with a double-sided adhesive layer, the fastening device 100 may be adhered to the housing body 10. However, the present invention is not limited thereto. For example, the bottom plate layer member 113 and the housing body 10 may also be locked with screws at the same time to fix the fastening device 100 to the housing body 10.

[0056] As Figure 5B shown, a fixing hole FH may be provided at the edge of the battery module 11 to correspond to a protruding end portion 121P of the fastening assembly 120. The protruding end portion 121P may be formed on the outer surface of the fastening body 121. As Figure 5CAs shown, when the fastening component 120 is in the fastened state, the fastening device 100 is fastened to the housing body 10. Specifically, the protruding end 121P of the fastening component 120 can be fixed in the fixing hole FH of the battery module 11 of the housing body 10, so that the fastening device 100 can be fastened to the housing body 10, thereby realizing the fixation of the battery module 11 in the laptop. Conversely, as Figure 5B shown, when the fastening component 120 is in the released state, the fastening device 100 can release the fastening with the battery module 11 of the housing body 10. Specifically, according to the process of switching the fastening component 120 from the fastened state back to the released state as described in Figure 2 , the fixation between the protruding end 121P and the fixing hole FH can be released.

[0057] Based on the above, the fastening device provided in the embodiment of the present invention utilizes the mobility of the fastening component between the grooves provided in the base component through the rotating shaft member to realize the switching of the fastening component between the released state and the fastened state. Thus, when the fastening device is applied to the housing component, it can provide the function of fastening important components (such as the battery module) provided on the housing body, and has the characteristic of being easily released when disassembly and repair are required. In addition, the fixing method of such a fastening component provided in the embodiment of the present invention is not likely to break or be damaged.

[0058] In summary, although the present invention has been disclosed above in embodiments, it is not intended to limit the present invention. Those skilled in the art of the present invention can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
