Description

TECHNICAL FIELD

[0001] The present invention relates to a key structure, and more particularly to a key structure with a detachable key cap. BACKGROUND

[0002] At present, the use of computers is a habit, and the keyboard is one of the indispensable input devices. The keyboard is composed of multiple key structures. Generally speaking, the key structure is connected by a scissors-type connecting piece to connect a key cap and a bottom plate, so that the key cap can perform a lifting action relative to the bottom plate.

[0003] Generally speaking, the bottom surface of the key cap has a water droplet hole structure and a sliding groove connecting structure. The scissors-type connecting piece has multiple connecting rods to be connected to the water droplet hole structure and the sliding groove, respectively. However, when the key cap needs to be disassembled, force needs to be applied to remove the connecting rod from the water droplet hole structure. In addition to the inconvenience of operation, it may also cause damage to the water droplet hole structure, and there is a need for improvement. SUMMARY

[0004] In view of the above problems, the main purpose of the present invention is to provide a key structure comprising a resilient member and a clamping assembly. By the novel structure of the resilient member and the clamping assembly, the problem of inconvenient disassembly and easy damage to the connecting structure of the key cap of the existing key structure is solved.

[0005] To achieve the above purpose, the present invention provides a key structure comprising a bottom plate, a key cap, a resilient member, a clamping assembly, a second fixing structure, and a connecting assembly. The key cap comprises a first fixing structure. The resilient member comprises a reset portion and a plate body portion. The reset portion has a bottom portion and a crown portion, and the bottom portion is arranged on the bottom plate. The plate body portion is connected to the crown portion of the reset portion. The clamping assembly is arranged on the plate body portion and faces the bottom plate. The second fixing structure is arranged on the plate body portion or the clamping assembly. The second fixing structure is detachably connected to the first fixing structure. The connecting assembly comprises a first frame and a second frame which are pivotally connected to each other. The opposite ends of the first frame and the second frame are connected to the bottom plate and the clamping assembly, respectively.

[0006] According to an embodiment of the present invention, the clamping assembly further comprises at least one pivot portion, at least one sliding groove, and a rib, and the rib connects the pivot portion and the sliding groove.

[0007] According to an embodiment of the present invention, the resilient member and the clamping assembly are integrally formed.

[0008] According to an embodiment of the present invention, the resilient member and the clamping assembly are made by embedding injection, over-molding injection, or double material injection.

[0009] According to an embodiment of the present invention, the reset portion is a dome structure.

[0010] According to an embodiment of the present invention, the plate body portion comprises multiple broken holes.

[0011] According to an embodiment of the present application, the elastic member further comprises a receiving groove disposed on the plate body portion and extending to the reset portion. The key cap further comprises a through column disposed in the receiving groove.

[0012] According to an embodiment of the present application, the elastic member further comprises at least one through protrusion. The through protrusion is disposed on a surface of the plate body portion facing the bottom plate and is close to at least one side edge of the plate body portion.

[0013] According to an embodiment of the present application, the hardness of the plate body portion is greater than the hardness of the reset portion.

[0014] According to an embodiment of the present application, the first fixing structure and the second fixing structure are connected to each other in a magnetic manner.

[0015] According to an embodiment of the present application, the first fixing structure and the second fixing structure are each a magnet. The first fixing structure is disposed on a bottom surface of the key cap facing the bottom plate, and the second fixing structure is disposed on the engaging assembly.

[0016] According to an embodiment of the present application, the first fixing structure is a clamping column. The second fixing structure is a through hole disposed on the plate body portion. The clamping column passes through the through hole.

[0017] As described above, the key structure according to the present application comprises a bottom plate, a key cap and a first fixing structure thereof, an elastic member, an engaging assembly, a second fixing structure, and a connecting assembly. The elastic member comprises a reset portion and a plate body portion. The engaging assembly is disposed on the plate body portion and faces the bottom plate, and is used to assemble with the connecting assembly. The second fixing structure is disposed on the plate body portion or the engaging assembly, and is detachably connected to the first fixing structure. By disposing the engaging assembly on the plate body portion of the elastic member, and assembling the engaging assembly with the connecting assembly, the connecting assembly does not need to be connected to the key cap. In addition, the first fixing structure of the key cap and the second fixing structure located on the elastic member or the engaging assembly are detachably connected to each other. Therefore, when the key cap needs to be replaced, the key cap can be removed by only releasing the connection between the first fixing structure and the second fixing structure, which is quite convenient. In addition, when the key cap is removed, since the connecting assembly is connected to the engaging assembly, the structure of the engaging assembly will not be damaged.

[0048] To better understand the technical content of the present application, the preferred embodiments are described as follows.

[0049] Figure 1 The schematic diagram of the key structure of the first embodiment of the present application, Figure 2 The exploded schematic diagram of the key structure, Figure 1 The schematic diagram of the key cap and the elastic member, the engagement assembly and the second fixed structure, Figure 3 The cross-sectional view of the combination of the key cap and the elastic member. Please refer to Figure 2 The cross-sectional view of the combination of the key cap and the elastic member. Please refer to Figure 4 The cross-sectional view of the combination of the key cap and the elastic member. Please refer to Figure 3 The cross-sectional view of the combination of the key cap and the elastic member. Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The key structure 1 of the present embodiment comprises a bottom plate 10, a key cap 20, an elastic member 30, an engagement assembly 40 and a connecting assembly 50. It should be noted that the bottom plate 10 shown in the drawings corresponds to one key structure 1, and in actual application, a plurality of key structures 1 correspond to one bottom plate 10.

[0050] As Figure 3 and Figure 4As shown, the keycap 20 includes a first fixing structure 21. Preferably, the first fixing structure 21 is disposed on the bottom surface of the keycap 20, facing the base plate 10. Correspondingly, the key structure 1 also includes a second fixing structure 60, which can be disposed on the elastic member 30 or the engaging assembly 40. In this embodiment, the engaging assembly 40 is disposed on the elastic member 30, and the second fixing structure 60 is disposed on the engaging assembly 40. Furthermore, the second fixing structure 60 is detachably connected to the first fixing structure 21, thereby making the keycap 20 detachably connected to the elastic member 30.

[0051] like Figure 4 As shown, the elastic member 30 in this embodiment includes a reset portion 31 and a plate portion 32. The reset portion 31 is a dome structure made of rubber, and has a bottom 311 and a crown 312. The plate portion 32 is connected to the crown 312 of the reset portion 31. In this embodiment, the reset portion 31 and the plate portion 32 are made of the same material, such as rubber. The plate portion 32 extends outward from the crown 312 of the reset portion 31 to form a plate. The rubber reset portion 31 can deform under pressure and return to its original shape when not under pressure, providing elasticity for the keycap 20 to return to its original position. The engaging assembly 40 is disposed on the plate portion 32 of the elastic member 30 for connection to the connecting assembly 50. In other embodiments, the reset portion 31 and the plate portion 32 of the elastic member 30 may also be made of different materials or with different component ratios, such that the hardness of the plate portion 32, where the engaging assembly 40 is disposed, is greater than the hardness of the reset portion 31.

[0052] In this embodiment, the engaging component 40 is disposed on the plate body 32 and faces the base plate 10. Specifically, the engaging component 40 includes at least one pivot portion 41 and at least one sliding groove 42, both of which are disposed on the plate body 32 and face the base plate 10. Specifically, portions of the pivot portion 41 and the sliding groove 42 are disposed on the plate body 32, and the remaining portions protrude from the lower surface of the plate body 32 toward the base plate 10. In this embodiment, the pivot portion 41 can be a teardrop-shaped structure. Since the elastic element 30 mainly provides the elastic force for the keycap 20 to return to its original position after being pressed, and the engaging component 40 is used for assembly with the connecting component 50, the two have different functions, so the elastic element 30 and the engaging component 40 are made of different materials. For example, the elastic element 30 can be made of rubber so that the reset portion 31 can provide the elastic force for the keycap 20 to return to its original position. The engaging component 40 can be made of a plastic material harder than rubber for connection with the connecting component 50.

[0053] Preferably, in this embodiment, the elastic element 30 and the engaging assembly 40 are integrally formed. For example, the elastic element 30 and the engaging assembly 40 are manufactured simultaneously by methods such as insert molding, overlay injection molding, or dual-material injection molding. In this embodiment, the engaging assembly 40 can be disposed in the plate portion 32 of the elastic element 30 by insert molding. Figure 2 and Figure 3 As shown, preferably, the engaging assembly 40 further includes a rib 43, and the rib 43 connects the pivot portion 41 and the slide groove 42. In this embodiment, the rib 43 is a quadrilateral frame to connect the two pivot portions 41 and the two slide grooves 42 respectively. The rib 43 not only increases the structural strength of the pivot portion 41 and the slide groove 42, but also facilitates the mold design for processes such as embedded injection, overlay injection, or dual-material injection.

[0054] Figure 5 for Figure 1 Please refer to the cross-sectional schematic diagram of the button structure shown. Figure 2 and Figure 5 As shown. The connecting component 50 of this embodiment includes a first frame 51 and a second frame 52 pivotally connected to each other to form a scissor-type connecting component. The opposite ends of the first frame 51 and the second frame 52 are respectively connected to the base plate 10 and the engaging component 40. Specifically, the opposite ends of the first frame 51 are respectively connected to the base plate 10 and the pivot portion 41, and the opposite ends of the second frame 52 are respectively connected to the base plate 10 and the slide groove 42. The base plate 10 is provided with multiple structures for connecting the first frame 51 and the second frame 52, such as multiple hooks (not shown in the figure), which are common structures in the art and will not be described in detail here. In this embodiment, the first frame 51 is an inner frame, one end of which is connected to the base plate 10, and the other end is connected to the pivot portion 41 of the engaging component 40 (e.g., a teardrop hole structure). The end of the first frame 51 connected to the base plate 10 is the moving end 511, and the end connected to the pivot portion 41 is the fixed end 512. In this embodiment, the second frame 52 is an outer frame, with one end connected to the base plate 10 and the other end connected to the slide groove 42 of the engaging assembly 40. The end of the second frame 52 connected to the base plate 10 is the fixed end 521, while the end connected to the slide groove 42 is the movable end 522.

[0055] In addition, the first frame 51 also includes a receiving hole 513, such as Figure 2 As shown. The reset part 31 of the elastic member 30 passes through the receiving hole 513, so that the bottom 311 of the reset part 31 is disposed above the base plate 10. When the keycap 20 is pressed or reset, the moving end 511 of the first frame 51 and the moving end 522 of the second frame 52 move on the base plate 10 or in the slide groove 42, thereby driving the keycap 20 to move up and down.

[0056] Please refer to Figure 2 ,Figure 3 and Figure 4 As shown above, in this embodiment, the second fixing structure 60 is disposed on the engaging assembly 40, and the second fixing structure 60 is detachably connected to the first fixing structure 21, thereby allowing the keycap 20 to be detachably connected to the elastic member 30. In this embodiment, the key structure 1 has four second fixing structures 60, which are respectively located on the pivot portion 41 and the slide groove 42. Specifically, the second fixing structures 60 are disposed on the surfaces (i.e., the upper surfaces) of the pivot portion 41 and the slide groove 42 facing the keycap 20. Preferably, the upper surfaces of the pivot portion 41 and the slide groove 42 may also have grooves for accommodating the second fixing structures 60.

[0057] Correspondingly, the keycap 20 has four first fixing structures 21, which are disposed on the bottom surface of the keycap 20 facing the base plate 10. Furthermore, the distribution positions of the first fixing structures 21 on the bottom surface of the keycap 20 correspond to the second fixing structures 60. In other embodiments, the second fixing structure 60 may also be disposed on the plate portion 32 of the elastic member 30, provided that the positions of the first fixing structures 21 correspond to the second fixing structures 60; this invention is not limited in this respect.

[0058] Preferably, in this embodiment, the first fixing structure 21 and the second fixing structure 60 are connected to each other by magnetic attraction. In this embodiment, the first fixing structure 21 and the second fixing structure 60 can each be a magnet, and the magnetic poles of their corresponding surfaces are opposite to attract each other. For example, the side surface of the first fixing structure 21 facing the base plate 10 is the N pole, and the side surface of the second fixing structure 60 facing the keycap 20 is the S pole, so that the first fixing structure 21 and the second fixing structure 60 can be connected to each other by magnetic attraction. The magnetic poles of the first fixing structure 21 and the second fixing structure 60 can also be configured in other ways, as long as the first fixing structure 21 and the second fixing structure 60 can correspond to each other. In other embodiments, one of the first fixing structure 21 and the second fixing structure 60 can be a magnet, and the other can be a magnetic element. For example, the first fixing structure 21 is a magnet, and the second fixing structure 60 is a magnetic element that can be attracted by a magnet. Alternatively, the first fixing structure 21 can be a magnetic element, and the second fixing structure 60 can be a magnet; the present invention is not limited to this.

[0059] Therefore, when it is necessary to remove the keycap 20, simply apply force to move the first fixing structure 21 of the keycap 20 away from the second fixing structure 60 to achieve the effect of removing the keycap 20. When it is necessary to assemble the keycap 20, simply place the keycap 20 on the plate portion 32 of the elastic member 30, and the keycap 20 will be assembled to the elastic member 30 due to the magnetic force attracted by the first fixing structure 21 and the second fixing structure 60.

[0060] By using the engaging component 40 disposed on the plate portion 32 of the elastic member 30, and the structure in which the engaging component 40 and the connecting component 50 are assembled, the connecting component 50 does not need to be connected to the keycap 20. The keycap 20 is detachably connected to the elastic member 30 or the engaging component 40 via the first fixing structure 21 and the second fixing structure 60. Therefore, when the keycap 20 needs to be replaced, it is only necessary to disconnect the connection between the first fixing structure 21 and the second fixing structure 60 to remove the keycap 20. In addition, when removing the keycap 20, the engaging component 40 remains connected to the connecting component 50, so the structure of the pivot portion 41 will not be damaged.

[0061] In this embodiment, the button structure 1 further includes a circuit board 70, which is disposed above the base plate 10. Similarly, the circuit board 70 shown in the accompanying drawings corresponds to one of the button structures 1; in practical applications, multiple button structures 1 correspond to one circuit board 70. Furthermore, the reset unit 31 also includes a trigger unit 313, such as... Figure 4 and Figure 5 As shown. When the keycap 20 is pressed, the reset part 31 deforms and the trigger part 313 moves downward and contacts the circuit board 70 to generate a corresponding trigger signal.

[0062] Preferably, the keycap 20 in this embodiment further includes a conductive post 22. Correspondingly, the elastic member 30 further includes a receiving groove 33. The receiving groove 33 is disposed on the plate body portion 32 and extends to the crown portion 312 of the reset portion 31. Specifically, the opening of the receiving groove 33 is located on the surface of the plate body portion 32, and the groove portion of the receiving groove 33 extends into the crown portion 312 of the reset portion 31, thereby positioning the receiving groove 33 above the trigger portion 313. When the keycap 20 is assembled to the elastic member 30, the conductive post 22 can be disposed in the receiving groove 33. When the keycap 20 is pressed, the conductive post 22 can further press down on the trigger portion 313 to assist the trigger portion 313 in touching the circuit board 70 downwards, thereby ensuring the generation of a corresponding trigger signal.

[0063] Preferably, the elastic element 30 of this embodiment further includes at least one conductive protrusion 34. The conductive protrusion 34 is disposed on a surface (i.e., the lower surface) of the plate body portion 32 facing the base plate 10, and is close to at least one side edge of the plate body portion 32. Preferably, the elastic element 30 of this embodiment may include four conductive protrusions 34, respectively located at the four corners of the plate body portion 32. Specifically, the plate body portion 32 of this embodiment is only slightly smaller than the bottom surface of the keycap 20. If the conductive protrusion 34 is close to the side edge or corner of the plate body portion 32, it is also close to the edge or corner below the keycap 20. When the user presses the edge or corner of the keycap 20, the conductive protrusion 34 can also move downward and contact the circuit board 70 to generate a corresponding trigger signal. In other words, when the edge or corner of the keycap 20 is pressed, the reset part 31 located in the center may not be able to deform effectively, so that the trigger part 313 cannot contact the circuit board 70, but the circuit board 70 can still be triggered by the conductive protrusion 34 near the side or corner of the board body part 32.

[0064] Figure 6 This is a schematic diagram of the button structure according to the second embodiment of the present invention. Figure 7 for Figure 6 Please refer to the schematic diagram of the elastic element shown. Figure 6 and Figure 7 As shown. The key structure 1a of this embodiment also includes a base plate 10, a keycap 20 and its first fixing structure 21, an elastic element 30a, a locking assembly 40, a connecting assembly 50, and a second fixing structure 60. The structure and connection relationship of the base plate 10, keycap 20, locking assembly 40, connecting assembly 50, and second fixing structure 60 are the same as in the first embodiment, so the component symbols are used accordingly. The elastic element 30a of this embodiment also includes a reset part 31a and a plate part 32a. The difference from the previous embodiment is that the plate part 32a of this embodiment includes multiple holes 321a. Preferably, the holes 321a are symmetrically arranged on the plate part 32a. The plate part 32a of this embodiment has four holes 321a. Figure 7 For example, the distribution of the perforations 321a gives the plate portion 32 a short axis 322a and a long axis 323a. Furthermore, the short axis 322a and the long axis 323a are 90 degrees apart. The perforations 321a are symmetrically distributed in the plate portion 32a about the short axis 322a. The presence of perforations 321a in the plate portion 32a reduces the overall weight of the elastic member 30a and also provides space for other structures.

[0065] Figure 8 This is a schematic diagram of the button structure according to the third embodiment of the present invention. Figure 9 for Figure 8 Please refer to the schematic diagram of the elastic element shown. Figure 8 and Figure 9As shown. The key structure 1b of this embodiment also includes a base plate 10, a keycap 20 and its first fixing structure 21, an elastic element 30b, a snap-fit ​​assembly 40, a connecting assembly 50, and a second fixing structure 60. The structure and connection relationship of the base plate 10, keycap 20, snap-fit ​​assembly 40, connecting assembly 50, and second fixing structure 60 are the same as in the first embodiment, so the component symbols are used accordingly. The elastic element 30b of this embodiment also includes a reset part 31b and a plate part 32b, and the plate part 32b includes multiple holes 321b. The difference from the previous embodiment is that the plate part 32b of this embodiment has four holes 321b. Preferably, the holes 321b of this embodiment are also symmetrically arranged on the plate part 32a. Figure 9 For example, the distribution of the perforations 321b gives the plate portion 32 a short axis 322b and a long axis 323b. The short axis 322b and the long axis 323b are 90 degrees apart, and a rib 324b is also present between the short axis 322b and the long axis 323b. The perforations 321b are symmetrically distributed on the plate portion 32b about the short axis 322b. Similarly, the perforations 321b in the plate portion 32b can reduce the overall weight of the elastic member 30b and can also provide space for other structures.

[0066] Figure 10 This is a schematic diagram of the button structure according to the fourth embodiment of the present invention. Figure 11 for Figure 10 Please refer to the cross-sectional view of the keycap and elastic element assembly shown below. Figure 10 and Figure 11 As shown. The key structure 1c of this embodiment also includes a base plate 10, a keycap 20c, an elastic element 30c, a locking assembly 40c, a connecting assembly, and a second fixing structure 60c. The structure and connection relationship of the base plate 10 and the connecting assembly are the same as in the first embodiment, so the base plate 10 uses the same component symbols, while the connecting assembly is not marked with component symbols because it is obscured by other components. The elastic element 30c of this embodiment also includes a reset part 31c and a plate part 32c, and the locking assembly 40c is also disposed on the plate part 32c of the elastic element 30c. The locking assembly 40c also has a pivot part 41c facing the base plate 10 and a sliding groove 42c, and the pivot part 41c and the sliding groove 42c are connected to each other by ribs 43c. The main difference from the previous embodiment is that the first fixing structure 21c and the second fixing structure 60c of the keycap 20c in this embodiment are different, and the second fixing structure 60c of this embodiment is disposed on the elastic element 30c. Therefore, in this embodiment, the upper surfaces of the pivot 41c and the slide 42c are only connected to the rib 43c, and there are no other structures that cooperate with the second fixing structure 60c.

[0067] In this embodiment, the first fixing structure 21c is a locking post, which includes a head 211c and a rod 212c. One end of the rod 212c is connected to the bottom surface of the keycap 20c, while the head 211c is located at the other end of the rod 212c. Correspondingly, the second fixing structure 60c is a through hole provided in the plate body 32c. The locking post (i.e., the first fixing structure 21c) passes through the through hole (i.e., the second fixing structure 60c), thereby allowing the second fixing structure 60c to be detachably connected to the first fixing structure 21c. In this embodiment, the maximum outer diameter of the first fixing structure 21c is larger than the inner diameter of the second fixing structure 60c (i.e., the through hole). Specifically, the outer diameter of the rod 212c is larger than the inner diameter of the second fixing structure 60c (i.e., the through hole). Since the plate portion 32c of the elastic element 30c is made of rubber, when the head 211c passes through the second fixing structure 60c (i.e., the perforation), the second fixing structure 60c can be enlarged first. After the head 211c passes through, the second fixing structure 60c is fitted onto the outside of the rod portion 212c. Conversely, when the keycap 20c needs to be removed, only force needs to be applied to the keycap 20c in a direction away from the base plate 10, so that the head 211c moves in the opposite direction and out through the second fixing structure 60c (i.e., the perforation). This connection method between the locking post and the perforation will not cause any damage to the pivot portion 41c structure of the locking assembly 40c when the keycap 20c is removed.

[0068] In summary, the key structure according to the present invention includes a base plate, a keycap and its first fixing structure, an elastic element, a snap-fit ​​assembly, a second fixing structure, and a connecting assembly. The elastic element includes a reset portion and a plate portion. The snap-fit ​​assembly is disposed on the plate portion and faces the base plate, and is used to assemble with the connecting assembly. The second fixing structure is disposed on the plate portion or the snap-fit ​​assembly, and is detachably connected to the first fixing structure. By having the snap-fit ​​assembly disposed on the plate portion of the elastic element, and assembled with the connecting assembly, the connecting assembly does not need to be connected to the keycap. Furthermore, the first fixing structure of the keycap and the second fixing structure located on the elastic element or the snap-fit ​​assembly are detachably connected to each other. Therefore, when the keycap needs to be replaced, it is only necessary to disconnect the connection between the first fixing structure and the second fixing structure to remove the keycap, which is quite convenient. In addition, when removing the keycap, since the connecting assembly is connected to the snap-fit ​​assembly, the structure of the snap-fit ​​assembly will not be damaged.

[0069] 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.
