Traditional key structure is when fitting with big key cap, except the axis body, still need be being provided with balanced structure, this balanced structure is including setting up two satellite axles in the relative both sides of axis body and the balanced strip of connecting these two satellite axles, like this, big key cap then has three position of being connected with this key structure, promptly, is connected with axis body and two satellite axles respectively. However, the conventional key structure has a complicated overall structure due to the addition of the satellite axis and the balance bar, and is complicated to assemble. In view of the above problems, the embodiments of the present application provide the following solutions:
referring to fig. 1 and 3, a key structure 100 of the present application includes a base 10, an upper cover 20, and a shaft structure 30. The base 10 and the cover 20 are adapted to be coupled to a base plate of a key device, and the shaft structure 30 is adapted to be coupled to a key cap 202.
Specifically, the base 10 is buckled with the upper cover 20, and the shaft structure 30 penetrates through the upper cover 20 and can move telescopically relative to the upper cover 20, so as to meet the pressing requirement of the key cap 202. The shaft structure 30 includes a main body portion 31, an extension portion 32, an adapter portion 33, and a plurality of balance portions 34.
Here, the main body 31 mainly plays a bearing role, and the extension portion 32, the fitting portion 33, and the balance portions 34 are connected.
The extension portion 32 is disposed at one side of the main body portion 31 and is adapted to the base 10, wherein the extension portion 32 is a rod or a similar rod structure and is adapted to the base 10 to prevent the shaft structure 30 from coming off the base 10.
The fitting portion 33 is disposed on the other side of the main body portion 31 and is fitted with the key cap 202, where the shape and structure of the fitting portion 33 are not limited so as to be fittingly connected with the key cap 202, for example, the key cap 202 is provided with a mounting post 204, the fitting portion 33 is a mounting sleeve fitted with the mounting post 204, and the mounting post 204 is inserted into the corresponding mounting sleeve. And, the number of the fitting portions 33 is also adjusted more practically.
Illustratively, the number of the fitting parts 33 is one, then, the fitting parts 33 are located at the central position of the main body part 31, such as the central point, or the geometric center, or the symmetric center, etc., and correspond to the extension parts 32, i.e., at this time, the extension parts 32 are also located at the central position of the main body part 31, so as to achieve smooth extension and retraction of the shaft structure 30 relative to the upper cover 20. And, each balance portion 34 is disposed around the fitting portion 33, so that the coupling position between the shaft structure 30 and the upper cover 20 is increased and the stability is improved.
Of course, in other embodiments, when facing a keycap 202 with a longer length, the number of the adapting portions 32 may be increased, so that the number of the direct connection positions between the shaft structure 30 and the keycap 202 is increased, so that the force transmission between the keycap 202 and the shaft structure 30 is more balanced, and a more pressing feeling is obtained.
Each balance part 34 and the adapting part 33 are arranged on the same side of the main body part 31, each balance part 34 is arranged around the adapting part 33, and the upper cover 20 is provided with a through hole structure 20a for limiting the balance part 34, so that the shaft structure 30 can stably extend and retract relative to the upper cover 20. It can be understood that the addition of the balance portion 34 improves the connection position between the shaft structure 30 and the upper cover 20, so that the shaft structure 30 is more stable in the lifting process relative to the upper cover 20, and especially when the size of the key cap 202 is too large, a user can ensure that the key cap does not deviate under the condition of uncertainty of pressing the position of the key cap 202, and then the shaft structure 30 is lifted smoothly relative to the upper cover 20. Here, the smooth pressing does not mean that the key cap 202 does not move with the fitting part 33 in an offset manner, but the probability of the movement in an offset manner is reduced, so that there is a smooth probability that a high probability occurs in the pressing of the key cap 202.
Specifically, for example, when the key cap 202 is a space key cap, a user often presses the opposite ends of the space key cap during use, so that the conventional key structure is prone to cause the space key cap to incline during pressing, which leads to a pressing and jamming condition, and after the balance part 34 is additionally provided, the number of connection positions between the outer wall of the shaft structure 30 and the inner wall of the through hole structure 20a of the upper cover 20 is increased, so that the shaft structure 30 is more moved relative to the upper cover 20.
Therefore, the shape and structure of each balance portion 34 and the position of each balance portion 34 on the main body 31 are not limited, so that the key cap 202 can be smoothly pressed down.
Illustratively, the balance portion 34 is a block structure having a circumferential side wall that matches a hole wall of the through-hole structure 20a of the upper cover 20. Alternatively, the balance portion 34 is a contoured structure having a circumferential side wall that is fitted with the hole wall of the through-hole structure 20a of the upper cover 20.
Illustratively, the shape and structure of each balance portion 34 are the same, and the adapted periphery is symmetrically disposed with the central axis of the adapted portion 33 as the symmetric center, so that the adapted portion 33 is matched with the hole wall of the through hole structure 20a of the upper cover 20 to be balanced in force. Alternatively, each balance portion 34 may be disposed on the main body 31 in an asymmetric manner, and only the force balance between the adapting portion 33 and the hole wall of the through hole structure 20a of the upper cover 20 in the adapting connection process needs to be achieved, for example, the distances from the center of gravity of each balance portion 34 to the central axis of the adapting portion 33 are equal, and the weights of each balance portion 34 are the same.
The application provides a key structure 100, set up a plurality of balancing parts 34 on axial structure 30, and, each balancing part 34 directly sets up on axial structure 30's the balancing part 34, compare in traditional key structure 100, balancing pole and support have been saved, in the assembly, key cap 202 directly packs into on axial structure 30, and with adaptation portion 33 looks adaptation connection, simultaneously, each balancing part 34 and the through-hole structure 20a looks adaptation of upper cover 20, promptly with the position of being connected between the upper cover 20 more, further increase the stability that axial structure 30 pushed down the process, finally, key cap 202 can steadily rise to descend and feel better relative key structure 100. In summary, the key structure 100 of the present application can be manufactured to obtain the shaft structure 30 by opening the mold once, and the installation of the balance bar and the bracket and the reserved installation space thereof are omitted, so that the structure of the key structure 100 is simpler, and the assembly process with the key cap 202 is also easy.

It can be understood that the balance parts 34 are identical in shape and structure and have the same weight, so that the central axis of the fitting part 33 of the shaft structure 30 is the force balance center of the whole shaft structure 30, and thus, when the force balance center of the key cap 202 is coincident with the central axis of the fitting part 33, the key cap 202 is more stable during the pressing down process.
For example, as shown in fig. 1, in the long key cap 202 such as a space key, the balance parts 34 and the fitting parts 33 are arranged in a line along the length direction of the long key cap 202. Thus, the force bearing area of each balance part 34 is the same as that of the inner wall of the long key cap 202. Or, the balancing parts 34 are arranged in a cross shape with the central axis of the adapting part 33 as the center, and similarly, the long keycap 202 can be stressed in a balanced manner in the pressing process.
Or, for example, when the key cap is large, for example, a key cap for carriage return or a key cap for blank space, the number of the balance parts 34 is more than two, and in this case, the balance parts 34 are disposed on the main body part 31 at intervals centering on the central axis of the fitting part 33. Likewise, the balance portions 34 are identical in shape and structure and equal in weight, so that the center axis of the fitting portion 33 of the shaft structure 30 is the center of force balance of the entire shaft structure 30.
