Detailed implementation manners

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are labeled with related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and general technical knowledge in the art.

[0049] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment, and do not mean that they are necessary sequences, unless it is stated otherwise that a certain sequence must be followed.

[0050] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0051] Mechanical keyboards can be divided into high-axis keyboards and low-axis keyboards according to the travel of the mechanical axes. For long keys with longer keycaps, satellite axes need to be set to ensure the balance of the long keycaps in the long keys. However, due to the different travels of the satellite axes corresponding to the long keys of high axes and low axes, the satellite axes cannot be used interchangeably, thus increasing the product manufacturing cost.

[0052] To address the above problems, the present application provides a long key component and a mechanical keyboard. By changing the installation position of the satellite axis in keys with different travels, it can adapt to keyboards with different travels, thereby being compatible with high-axis keyboards and low-axis keyboards and further reducing the product manufacturing cost.

[0053] Embodiment 1

[0054] This embodiment provides a long key component, which is applied to a mechanical keyboard. Among them, the long key component can be keys such as the "space bar", "delete key", "enter key", etc.

[0055] See Figures 1 - 12As shown in the figure, the long key component 100 provided in this embodiment includes: a circuit board 10, a positioning plate 20, a mechanical main shaft 30, a long key cap 40, and a satellite shaft balance structure 50. Among them, the long key cap 40 is the key cap of relatively long keys such as the "space key", "delete key", and "enter key". The positioning plate 20 is disposed at an interval above the circuit board 10. The mechanical main shaft 30 is installed on the positioning plate 20 and is electrically connected to the circuit board 10. The long key cap 40 is movably installed on the positioning plate 20 through the mechanical main shaft 30. Pressing the long key cap 40 can trigger the switch on the circuit board 10 by the mechanical main shaft 30 to execute the key function.

[0056] It should be noted that the mechanical main shaft 30 can be divided into a high shaft and a low shaft according to different strokes. The high shaft means that the mechanical main shaft 30 has a longer stroke, and the low shaft means that the mechanical main shaft 30 has a shorter stroke. When the mechanical main shaft 30 is a high shaft, the satellite shaft balance structure 50 can be fixedly installed on the positioning plate 20. When the mechanical main shaft 30 is a low shaft, the satellite shaft balance structure 50 can be fixedly installed on the circuit board 10, and by changing the structures on the positioning plate 20 and the circuit board 10 for installing the satellite shaft balance structure 30, the satellite shaft balance structure 50 can be adapted to high shaft keys and low shaft keys. For specific details, please refer to the subsequent embodiments.

[0057] The satellite shaft balance structure 50 includes a balance rod 51 and two satellite shafts 52. The two satellite shafts 52 are respectively disposed on both sides of the mechanical main shaft 30 and are connected to the long key cap 40, and can balance the force of the long key cap 40 when pressing the long key cap 40.

[0058] See Figure 2 、 Figure 7 and Figure 8 As shown in the figure, the satellite shaft 52 includes a shaft housing 521 and a shaft core 522. The shaft housing 521 is provided with a sliding cavity 5210 in a penetrating manner. One end of the shaft core 522 is slidably installed in the sliding cavity 5210, and the other end of the shaft core 522 extends to the outside of the top end of the shaft housing 521 and is connected to the long key cap 40. The balance rod 51 has a connecting rod 511 and two inserting rods 512. The two inserting rods 512 are respectively connected to both ends of the connecting rod 511, and the two inserting rods 512 are respectively inserted into the inside of the shaft housing 521 and are connected to the shaft core 522.

[0059] When the user presses the long key cap 40, the shaft core 522 slides downward relative to the shaft housing 521 within the sliding cavity 5210 of the shaft housing 521. The shaft core 522 forces the free end of the insertion rod 512 of the balance rod 51 to move downward along with the shaft core 522, synchronously driving the connecting rod 511 of the balance rod 51 to rotate downward relative to the shaft housing 521. During this process, the connecting rod 511 of the balance rod 51 can synchronously drive the two shaft cores 522 to slide within the corresponding sliding cavities 5210 through the two insertion rods 512 to complete the pressing. Then, under the action of the resilience of the mechanical main shaft 30, the long key cap 40 rebounds upward, driving the shaft core 522 to slide upward relative to the shaft housing 521 within the sliding cavity 5210 of the shaft housing 521. The shaft core 522 forces the free end of the insertion rod 512 of the balance rod 51 to slide upward along with the shaft core 522, synchronously driving the connecting rod 511 of the balance rod 51 to rotate upward relative to the shaft housing 521. During this process, the connecting rod 511 of the balance rod 51 can synchronously drive the two shaft cores 522 to move synchronously within the corresponding sliding cavities 5210 under the action of the two insertion rods 512, enabling the shaft core 522 to rebound.

[0060] As Figures 7 - 10 shown, a positioning component 5211 is provided on the outer periphery of the shaft housing 521, and this positioning component 5211 can fix the shaft housing 521 to the corresponding position.

[0061] As Figures 1 - 4 shown, the positioning plate 20 is provided with a first avoidance hole 21 and two first positioning holes 22 in a through - hole manner. The first avoidance hole 21 is arranged between the two first positioning holes 22 and communicates with the first positioning holes 22 to avoid the connecting rod 511 of the balance rod 51, that is, when the connecting rod 511 rotates upward, the connecting rod 511 can be avoided through the first avoidance hole 21. The two first positioning holes 22 respectively correspond to the shaft housings 521 of the two satellite shafts 52. The shaft housings 521 of the two satellite shafts 52 are respectively inserted through the two first positioning holes 22 and are positioned on the positioning plate 20 through the positioning component 5211, that is, the shaft housing 521 is fixed on the positioning plate 20.

[0062] Or,

[0063] As Figure 5 and Figure 6 shown, the positioning plate 20 is provided with an installation hole 23 in a through - hole manner, and the circuit board 10 is provided with two second positioning holes 11 in a through - hole manner. The two second positioning holes 11 respectively correspond to the shaft housings 52 of the two satellite shafts 52. The shaft housings 521 of the two satellite shafts 52 respectively pass through the installation hole 23 so that the shaft housing 521 is inserted through the two second positioning holes 11 and are positioned on the circuit board 10 through the positioning component 5211.

[0064] In the first implementation, when using the positioning plate 20 provided with the first avoidance hole 21 and two first positioning holes 22, the shaft housing 521 is inserted through the first positioning hole 22, and the shaft housing 521 is fixed to the positioning plate 521 through the positioning component 5211.

[0065] In the second implementation, when using the positioning plate 20 provided with the mounting hole 23 and the circuit board 10 provided with two second positioning holes 11, the shaft housing 521 passes through the mounting hole 23 and then is inserted through the second positioning hole 11, and is fixed to the circuit board 10 through the positioning component 5211.

[0066] It should be noted that the stroke of the shaft core 522 relative to the shaft housing 521 in the satellite shaft balance structure 50 provided in this embodiment remains unchanged. Moreover, since the positioning plate 20 is located above the circuit board 10, in the first implementation where the shaft housing 52 passes through the first positioning hole 21 of the positioning plate 20 and is fixed to the positioning plate 20 through the positioning component 5211, compared with the second implementation where the shaft housing 52 passes through the mounting hole 23 and is inserted through the second positioning hole 11 of the circuit board 20 and is fixed to the circuit board 10 through the positioning component 5211, among them, compared with the first implementation, the second implementation is equivalent to installing the shaft housing 52 in a sunken manner. The stroke of the shaft housing 521 in the first implementation is greater than the stroke of the shaft housing 521 in the second implementation. Thus, the first implementation can adapt to high-axis keys, and the second implementation can adapt to low-axis keys.

[0067] As above, when using the positioning plate 20 provided with the first avoidance hole 21 and two first positioning holes 22, the shaft housing 521 is inserted through the first positioning hole 22, and the shaft housing 521 is fixed to the positioning plate 521 through the positioning component 5211, enabling the satellite shaft balance structure 50 to adapt to high-axis keys. When using the positioning plate 20 provided with the mounting hole 23 and the circuit board 10 provided with two second positioning holes 11, the shaft housing 521 passes through the mounting hole 23 and then is inserted through the second positioning hole 11, and is fixed to the circuit board 10 through the positioning component 5211, enabling the satellite shaft balance structure 50 to adapt to low-axis keys. Thus, after changing the structures on the positioning plate 20 and the circuit board 10 for installing the shaft housing 521, the stroke of the shaft housing 521 can be relatively changed to adapt to high-axis keys or low-axis keys, so as to reduce the product manufacturing cost.

[0068] Specifically, in order for the satellite shaft balance structure 50 to pass through the mounting hole 23, the shape of the mounting hole 23 is the same as or substantially the same as the shape formed by the first avoidance hole 21 and two first positioning holes 22.

[0069] See Figures 7 - 10As shown in the figure, the positioning component 5211 includes: a first convex portion 52111, a second convex portion 52112, and a buckle portion 52113. Among them, the first convex portion 52111 is disposed on the first side surface of the shaft housing 521, and the second convex portion 52112 and the buckle portion 52113 are both disposed on the second side surface of the shaft housing 521. The first side surface and the second side surface of the shaft housing 521 are opposite side surfaces of the shaft housing 521. The first convex portion 5211 faces the bottom end of the shaft housing 521 and has a first contact end surface 52114, and the second convex portion 52112 faces the bottom end of the shaft housing 521 and has a second contact end surface 52115. The first contact end surface 52114 and the second contact end surface 52115 are in the same plane.

[0070] After the shaft housing 521 is inserted into the first positioning hole 22 of the positioning plate 20, the first contact end surface 52114 and the second contact end surface 52115 can simultaneously abut against the surface of the positioning plate 20 facing away from the circuit board 10, and the buckle portion 52113 can be snapped onto the surface of the positioning plate 20 facing the circuit board 10. Thus, the shaft housing 521 is fixed to the positioning plate 20 through the cooperation of the buckle portion 52113 with the first convex portion 52111 and the second convex portion 52112.

[0071] After the shaft housing 521 passes through the mounting hole 23 of the positioning plate 20 and is inserted into the second positioning hole 11 of the circuit board 10, the first contact end surface 52114 and the second contact end surface 52115 can simultaneously abut against the surface of the circuit board 10 facing the positioning plate 20, and the buckle portion 52113 can be snapped onto the surface of the circuit board 10 facing away from the positioning plate 20. Thus, the shaft housing 521 is fixed to the circuit board 10 through the cooperation of the buckle portion 52113 with the first convex portion 52111 and the second convex portion 52112.

[0072] In an embodiment of the present application, an elastic arm 52116 is provided on the second side surface of the shaft housing 521, and the buckle portion 52113 is disposed on the elastic arm 52116. After the shaft housing 521 is inserted into the first positioning hole 22 of the positioning plate 20 or the shaft housing 521 passes through the mounting hole 23 of the positioning plate 20 and is inserted into the second positioning hole 11 of the circuit board 10, under the action of the elastic arm 52116, the buckle portion 52113 can be snapped onto the surface of the positioning plate 20 facing the circuit board 10 or onto the surface of the circuit board 10 facing away from the positioning plate 20.

[0073] See Figures 7 - 10As shown, a tight reinforcement bar 5213 is provided on the third side surface and / or the fourth side surface of the shaft housing 521. When the shaft housing 521 is inserted into the first positioning hole 22 of the positioning plate 20 and fixed on the positioning plate 20, the tight reinforcement bar 5213 cooperates with the peripheral wall of the first positioning hole 22 to fill the tolerance gap between the shaft housing 521 and the peripheral wall of the first positioning hole 22, so that the shaft housing 521 is firmly defined on the positioning plate 20 in the tangential and normal directions, avoiding the phenomenon of loosening or shaking of the shaft housing 521 in the tangential and normal directions of the positioning plate 20.

[0074] Alternatively, when the shaft housing 521 passes through the mounting hole 23 of the positioning plate 20 to be inserted into the second positioning hole 11 of the circuit board 10 and fixed on the circuit board 10, the tight reinforcement bar 5213 cooperates with the peripheral wall of the second positioning hole 11 to fill the tolerance gap between the shaft housing 521 and the peripheral wall of the second positioning hole 11, so that the shaft housing 521 is firmly defined on the circuit board 10 in the tangential and normal directions, avoiding the phenomenon of loosening or shaking of the shaft housing 521 in the tangential and normal directions of the circuit board 10.

[0075] To facilitate the insertion of the insertion rod 512 into the interior of the shaft housing 521, as Figure 7 、 Figure 8 and Figure 10 shown, a third convex portion 5214 is further provided on the first side surface of the shaft housing 521. The third convex portion 5214 is provided with a plug-in groove 52141. The plug-in groove 52141 communicates with the sliding cavity 5210. An articulated groove 52142 is further provided at one end of the plug-in groove 52141 away from the sliding cavity 5210. The free end of the insertion rod 512 is connected to the shaft core 522 through the plug-in groove 52141, and the connecting rod 511 is rotatably located in the articulated groove 52142.

[0076] As Figure 11 and Figure 12 shown, the shaft core 522 is penetrated with an insertion groove 5221 for the free end of the insertion rod 512 to be inserted and connected. The insertion rod 512 is inserted into the insertion groove 5221 through the plug-in groove 52141, so that the insertion rod 512 is connected to the shaft core 522.

[0077] To enable the shaft core 522 to slide smoothly in the sliding cavity 5210 of the shaft housing 521, as Figure 9 and Figure 10 shown, a guide rib 52101 is further provided in the sliding cavity 5210. The guide rib 5210 extends along the sliding direction of the shaft core 522. Among them, the guide rib 52101 can be provided on each side wall in the sliding cavity 5210, or provided on two opposite or only one side wall.

[0078] In some embodiments, the outer peripheral surface of the guiding rib 52101 is arranged as an arc surface, so that the friction between the guiding rib 52101 and the peripheral wall of the shaft core 522 forms a line friction, thereby reducing the friction area and improving the smoothness, stability and reliability of the relative sliding of the shaft core 522 with respect to the shaft shell 521.

[0079] In this embodiment, as Figures 7 - 10 shown, a limiting notch 5212 is provided on the cavity wall of the sliding cavity 5210. As Figure 11 and Figure 12 shown, a stop portion 5222 is provided on the outer periphery of the shaft core 522. The stop portion 5222 cooperates with the limiting notch 5212 to limit the upward sliding displacement of the shaft core 522.

[0080] Embodiment Two

[0082] In one embodiment, as Figure 13 and Figure 14 shown, this mechanical keyboard further includes a first frame 60 and a first bottom cover 70. The first frame 60 has a first side surround 61 and a first top frame 62. The first top frame 62 is arranged at the top of the first side surround 61.

[0084] In this embodiment, the width of the first side surround 61 is greater than the width of the second side surround 81. Thus, when the first frame 60 and the first bottom cover 70 are adopted, it is to adapt to high-axis keys, and when the second frame 80 and the second bottom cover 90 are adopted, it is to adapt to low-axis keys.

[0085] Of course, in other embodiments, the first bottom cover 70 and the second bottom cover 90 can be universal, and only by replacing the first frame 60 or the second frame 80 to adapt to high-axis keys or low-axis keys, thereby further reducing the product manufacturing cost.

[0086] In summary, for the long key component and the mechanical keyboard provided by the present application, when using a positioning plate provided with a first avoidance hole and two first positioning holes, the shaft housing is inserted into the first positioning hole, and the shaft housing is fixed on the positioning plate through a positioning component, so that the satellite axis balance structure can adapt to high-axis keys. When using a positioning plate provided with a mounting hole and a circuit board provided with two second positioning holes, the shaft housing passes through the mounting hole and then is inserted into the second positioning hole, and is fixed on the circuit board through a positioning component, so that the satellite axis balance structure can adapt to low-axis keys. Thus, after changing the structures on the positioning plate and the circuit board for mounting the shaft housing, the stroke of the shaft housing can be relatively changed, so as to adapt to high-axis keys or low-axis keys, thereby reducing the product manufacturing cost.
