[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0028] The following describes a novel crystal key assembly and an assembly system having the same according to an embodiment of the utility model with reference to the accompanying drawings.
[0029] like Figure 1 and 2 As shown, the novel crystal key assembly of the utility model comprises a crystal key 1 and a key base frame 6, and the crystal key 1 and the key base frame 6 are clamped.
[0030] The crystal key 1 includes a key body 2 and a key matching plate 3. The key body 2 has a pressing end face 4 and a first end face (not shown in the figure). The pressing end face 4 and the first end face are arranged opposite to each other. The pressing end face 4 is a face used for pressing operation, and the first end face is a face used for connecting with the key matching plate 3. The first end face extends around the key matching plate 3, that is, relative to the first end face, the end face area of the key matching plate 3 is larger, so that the edge of the key matching plate 3 protrudes from the first end face.
[0031] The key body 2 and the key matching plate 3 can be integrally formed, that is, mold injection molding is adopted. It is understandable that in some embodiments, the key body 2 and the key matching plate 3 can also be connected in other ways, such as bonding.
[0032] In some embodiments, the crystal button 1 is made of transparent PC material.
[0033] The key chassis 6 is snap-fitted with the key matching plate 3 , so that the key chassis 6 is snap-fitted and connected with the crystal key 1 .
[0034] Specifically, the button limiting grooves 5 are provided on two opposite sides of the button matching plate 3 , and buckles 7 are provided on two opposite sides of the button base frame 6 , and the buckles 7 are engaged with the button limiting grooves 5 .
[0035] It can be understood that two key limit slots 5 can be opened on the key matching plate 3, the two key limit slots 5 are arranged opposite to each other, and the two key limit slots 5 are matched and snap-connected with two buckles 7 arranged on the key base frame 6; four key limit slots 5 can also be opened on the key matching plate 3, that is, key limit slots 5 are opened on the four sides of the key matching plate 3, and the four key limit slots 5 are matched and snap-connected with four buckles 7 arranged on the key base frame 6.
[0036] A protrusion 8 is set at the center of the end face of the key chassis 6 away from the key matching plate 3. Specifically, the key chassis 6 is clamped with the key matching plate 3 so that one end face of the key chassis 6 contacts the key matching plate 3, and a protrusion 8 is set at the center of the end face opposite to the end face.
[0037] It can be understood that the size of the protrusion 8 can be set according to specific circumstances. Preferably, the end surface of the protrusion 8 is an arc-shaped surface.
[0038] In some embodiments, the button chassis 6 and the buckle 7 are integrally formed, that is, mold injection molding is adopted.
[0039] In some embodiments, the key chassis 6 is a composite material, which is composed of PBT and PC.
[0040] like Figure 3-5 As shown, the crystal key assembly system includes a panel 13, a crystal key component array, an oil-proof PU film 10, a pressing plate 11 and a key panel 9 which are sequentially arranged along the key pressing direction.
[0041] The crystal key assembly array is composed of a plurality of crystal key assemblies arranged in an array, and the protrusion 8 of the key chassis 6 faces the oil-proof PU film 10 and is in contact with the oil-proof PU film 10 . The contact surface between the protrusion 8 and the oil-proof PU film 10 is small.
[0042] The pressing plate 11 has a through hole corresponding to the protrusion 8, and the protrusion 8 passes through the through hole to press and contact the key on the key plate 9. Specifically, the oil-proof PU film 10 is arranged between the pressing plate 11 and the crystal key assembly array, and the pressing plate 11 has a through hole corresponding to the protrusion 8 of the crystal key assembly array. During the pressing process, the protrusion 8 passes through the through hole to press and contact the key on the key plate 9, and the contact surface between the protrusion 8 and the key plate 9 is small.
[0043] Oil-proof foam 12 is arranged around the crystal key assembly array. Since the protrusion 8 of the crystal key assembly contacts the oil-proof PU film 10, the distance between the contact surface and the edge of the oil-proof foam 12 is increased, thereby improving the feel of the edge keys.
