As shown in the drawings, the present embodiment provides a key structure 1, which includes a bottom plate 11, a lifting assembly 13 and a key cap 15. The base plate 11 has a pivot assembly 111 and a limiting assembly 113, the pivot assembly 111 is located at one side of the limiting assembly 113, the pivot assembly 111 has an assembling opening 1110, an opening direction F of the assembling opening 1110 has an offset angle C away from the limiting assembly relative to a vertical direction E of the base plate 11, and the offset angle C is greater than 0 degree and less than or equal to 90 degrees. In the present embodiment, the bottom plate 11 is made of metal, such as aluminum plate, and the pivot assembly 111 and the limiting assembly 113 are made of plastic, and are formed on the bottom plate 11 by injection molding. In addition, the lifting assembly 13 includes a first bracket 131 and a second bracket 133 pivotally connected to each other, a first connecting shaft 1311 is disposed at a side of the first bracket 131, the first connecting shaft 1311 is assembled to the pivoting assembly 111 through the assembling opening 1110, a second connecting shaft 1331 is disposed at a side of the second bracket 133, and the second connecting shaft 1331 is movably disposed on the limiting assembly 113. The key cap 15 is disposed on the top of the lifting assembly 13 and can be moved up and down relative to the base plate 11 by the lifting assembly 13.

Fig. 4 is an exploded side view of the key structure according to the first embodiment of the present application. As shown, the hinge assembly 111 includes two hinges 1111, an opening direction F of the assembly opening 1110 of each hinge 1111 is far away from the limiting element 113, in other words, the opening direction F of the assembly opening 1110 is outward, and the assembly opening 1110 has an outward offset angle C with respect to a vertical direction E of the base plate 11 (i.e., a lifting direction of the lifting element 13 and the key cap 15), wherein the offset angle C is between 10 and 30 degrees, that is, the opening direction F of the assembly opening 1110 of the hinge assembly 111 is offset 10 to 30 degrees with respect to the vertical direction E of the base plate 11. The first bracket 131 has two first connecting shafts 1311, the first connecting shafts 1311 are respectively located at two sides of the first bracket 131, and after the two first connecting shafts 1311 of the first bracket 131 are assembled to the hinge member 1111 through the assembling opening 1110, the two first connecting shafts 1311 of the first bracket 131 are not easily separated from the assembling opening 1110 of the hinge member 1111 along the lifting direction of the key cap 15 because the assembling opening 1110 has an angular offset. It should be noted that the present application does not limit the range of the offset angle C, and in fact, as long as the assembling opening 1110 is offset away from the limiting component 113, the two first connecting shafts 1311 of the first bracket 131 are not easily separated from the two pivoting components 1111 of the pivoting component 111.

In the present embodiment, each pivot 1111 has an assembly hole 1112, and the assembly hole 1112 has a first opening 1113 and a second opening 1114, and the first opening 1113 and the second opening 1114 are connected to each other. In addition, the first connecting shaft 1311 is fitted to the second hole portion 1114 through the first hole portion 1113 at the time of assembly. The outer diameter of the first connecting shaft 1311 is greater than or equal to the bore diameter D1 of the first bore portion 1113, and the outer diameter of the first connecting shaft 1311 is less than or equal to the bore diameter D2 of the second bore portion 1114. The two first connecting shafts 1311 of the first holder 131 of the present embodiment are respectively pressed through the first hole portions 1113 of the assembly holes 1112, and the two first connecting shafts 1311 are fitted into the second hole portions 1114, so that the two first connecting shafts 1311 are not easily separated from the first hole portions 1113 of the assembly holes 1112.

Furthermore, each pivot member 1111 further has a fixing portion 1115, the fixing portion 1115 is disposed on a side of the pivot member 1111 away from the first bracket 131, and the fixing portion 1115 is disposed on a side of the second opening portion 1114. When the two first connecting shafts 1311 of the first bracket 131 are fitted in the second opening 1114, the fixing portion 1115 is located on one side of the end surface of the first connecting shaft 1311. The fixing portion 1115 can further enhance the structural strength of the pivot member 1111, so that the assembling holes 1112 of the pivot member 1111 are not easily deformed due to the external force. Thus, when the two first connecting shafts 1311 rotate in the pivot member 1111, the assembling holes 1112 are not easily opened to disengage from the pivot member 1111, so as to reduce the probability of the first bracket 131 disengaging from the base plate 11.

In addition, the limiting assembly 113 includes two limiting members 1131, and the two limiting members 1131 limit the moving path of the two second connecting shafts 1331 of the second bracket 133. Thus, the first bracket 131 and the second bracket 133 of the lifting assembly 13 are connected to the base plate 11 through the two pivot members 1111 and the two limiting members 1131, respectively, and can move up and down relative to the base plate 11.

Further, the key structure 1 further includes an elastic member 17, wherein the elastic member 17 is disposed on the bottom plate 11 and located between the first bracket 131 and the second bracket 133. When the key cap 15 is pressed, the elastic member 17 is elastically deformed, thereby providing a restoring force that moves the key cap 15 upward with respect to the base plate 11.

Referring to fig. 5 to 7, fig. 5 is an exploded view of a key structure according to a second embodiment of the present application, fig. 6 is another exploded view, and fig. 7 is an enlarged view of a region B of fig. 6. As shown in the drawings, the main difference of the present embodiment compared to the first embodiment is the opening direction G of the assembly opening 1110A of the pivot assembly 111A. In the present embodiment, the opening direction G of the assembly opening 1110A is shifted by 90 degrees with respect to the vertical direction of the bottom plate 11, in other words, the opening direction G of the assembly opening 1110A is parallel to the surface of the bottom plate 11. The pivot assembly 111A includes two pivot members 1111A, each pivot member 1111A has an assembly recess 1116, and the assembly recess 1116 is formed by combining the pivot member 1111A and the bottom plate 11. The assembly notch 1116 has an assembly opening 1110A, and when assembled, the first connecting shaft 1311 abuts against the inner wall of the assembly notch 1116 through the assembly opening 1110A, wherein the outer diameter of the first connecting shaft 1311 is smaller than the caliber D3 of the assembly opening 1110A, and the outer diameter of the first connecting shaft 1311 is equal to the caliber D4 of the assembly notch 1116.

Please refer to fig. 8, which is an exploded side view of the key structure according to the second embodiment of the present application. As shown in the drawings, in the present embodiment, each pivot member 1111A further has a fixing portion 1117, the fixing portion 1117 is disposed on a side of the pivot member 1111A away from the first bracket 131, and the fixing portion 1117 is located on a side of the assembly recess 1116, when the two first connecting shafts 1311 are embedded in the assembly recess 1116, the fixing portion 1117 is located on a side of an end surface of the first connecting shaft 1311. The fixing portion 1117 can further enhance the structural strength of the pivot component 1111A, so that the assembly recess 1116 of the pivot component 1111A is not easily deformed by external force. Thus, when the two first connecting shafts 1311 rotate in the hinge 1111A, the assembling recess 1116 is not easily opened to disengage from the hinge 1111A, thereby reducing the probability of the first bracket 131 disengaging from the base plate 11. In addition, the fixing portion 1117 may also enhance the connection strength between the pivot 1111A and the base plate 11.

To sum up, the present application provides a button structure, the opening direction of the assembly opening of the pin joint component through the bottom plate has an offset angle relative to the vertical direction of the bottom plate, and the first support of the lifting component is assembled in the pin joint component from the assembly opening.
