Description

Technical Field

[0001] The utility model relates to the technical field of peripheral electronic input equipment, in particular to an adaptive soft-spring keyboard. Background Art

[0002] As a peripheral electronic input device, the keyboard is composed of different key technologies and electronic switch systems. Its main function is to input data and can be used to operate other machines or devices in the computer system.

[0003] In order to meet the demand of some people for soft and elastic key feel, a keyboard currently has a silicone elastic member arranged on a circuit board module, so that the circuit board module has elastic buffering performance, thereby making the keys on the circuit board module have a soft and elastic feel.

[0004] In order to solve the problems of limited elasticity and travel of silicone elastic parts, easy aging and insufficient service life, another keyboard is currently equipped with a rebound component between the key substrate and the lower cover of its keyboard body, the rebound component includes an upper fixed block, a lower fixed block, a slider, an upper boss, a lower boss and a spring, the upper fixed block is integrally formed and installed on the outer side wall of the key substrate, the lower fixed block is provided with two left and right blocks, both of which are integrally formed and installed on the top position of the lower cover near the outer periphery, the lower boss is integrally formed and installed on the lower cover between the left and right lower fixed blocks, the bottom of the upper boss movably extends into the lower boss, and the upper boss The top of the slider is mounted on the outer periphery of the upper boss, and the spring is sleeved on the outer periphery of the lower boss. The upper and lower ends of the spring are respectively mounted on the slider and the lower cover. A convex block is mounted on the slider on one side facing the left and right lower fixed blocks. The convex block extends into the preset groove on the corresponding lower fixed block to form a limited sliding support. Therefore, when a keyboard key is pressed, feedback is given to the key substrate, and the key substrate is pressed down. When it drops, the slider compresses the spring to shrink it. At the same time, the slider moves down to reduce the distance between the key substrate and the lower cover. When the pressure stops, the spring recovers its deformation and pushes the key substrate up to reset.

[0005] However, the existing keyboards provided with a rebound component require the provision of characteristic components such as an upper fixed block, a lower fixed block, a sliding block, an upper boss, a lower boss and a spring, which has a complex structure and increases the production cost. In addition, the rebound limit of the rebound component of the existing keyboard is performed by a protrusion, that is, the protrusion is blocked on the upper arm in the groove after rebound and reset, but the protrusion and the upper arm in the groove are in rigid collision contact, and there is rigid collision noise. With the increase of usage time and aging of components, the rigid collision noise will become louder and louder, greatly affecting the user experience.

[0006] In addition, the rebound component of the existing keyboard is arranged between the key substrate and the lower cover, so the lower cover needs to be fixedly connected to the upper cover of the keyboard, and an additional adjustment bracket needs to be arranged on the bottom end surface of the lower cover, and one end of the adjustment bracket is rotatably hinged to the bottom end surface of the lower cover through a hinge structure, so that the height of one end of the keyboard can be adjusted by controlling the adjustment bracket to rotate relative to the lower cover, so that the tilting angle of the keyboard can be adjusted to meet different usage requirements of users. However, the existing keyboard needs to be additionally provided with an adjustment bracket to adjust its tilting angle, which is complex in structure and increases production costs.

When the key is released and reset, the spring elastically resets, forcing the suspension plate to drive the circuit board to reset upward in the direction of the keyboard height.

The utility model adaptive soft-elastic keyboard can achieve a soft and moist key feel by setting a limit column on the upper cover and opening a through hole in the suspension plate to adapt to the elastic pad, spring, and blocking part. The structure is simple and compact, thereby saving production costs. At the same time, the elastic life of the spring is long, thereby delaying the service life of the keyboard. In addition, the utility model adaptive soft-elastic keyboard does not have a rigid collision, can eliminate the rigid collision noise, achieve the purpose of silencing, and enhance the user experience. In addition, the utility model adaptive soft-elastic keyboard can be selectively supported on a support table in a horizontal or vertical position, thereby meeting the different placement and use requirements of users, thereby enhancing the user experience.

[0041] See also Figures 1 to 18The present embodiment discloses an adaptive soft-elastic keyboard 10, comprising an upper cover 11, a suspension plate 19, a lower cover 17 and a circuit board 18. The circuit board 18 is arranged on the suspension plate 19. The upper cover 11 is located at the upper end of the suspension plate 19 in the keyboard height direction Z. The lower cover 17 is located at the lower end of the suspension plate 19 in the keyboard height direction Z. A plurality of keys 14 are arranged on the circuit board 18. The keys 14 are arranged to pass through the upper cover 11 in the keyboard height direction Z. In addition, the adaptive soft-elastic keyboard 10 of the present embodiment further comprises an elastic pad 115 and a spring 117. The suspension plate 19 is provided with a through hole 191 in the keyboard height direction Z. A limiting column 114 is protruded from the lower end of the upper cover 11 near the suspension plate 19. The lower end of the limiting column 114 extends in the keyboard height direction Z and passes through the through hole 191. A blocking portion 1161 is arranged at the lower end of the limiting column 114. In addition, the through hole 191 of this embodiment can slide relative to the limit column 114 in the keyboard height direction Z, the elastic pad 115 is sleeved on the limit column 114 and pressed between the upper cover 11 and the suspension plate 19, and the spring 117 is sleeved on the limit column 114 and pressed between the suspension plate 19 and the blocking portion 1161. In addition, the lower cover 17 of this embodiment is respectively extended in the keyboard width direction Y and the keyboard length direction X to correspond to the upper cover 11, and the rear end of the lower cover 17 is rotatably hinged with the rear end of the upper cover 11 in the keyboard width direction Y. Specifically, a key cap 12 is provided at the upper end of each key 14.

[0042] The upper cover 11 of the adaptive soft-elastic keyboard 10 of this embodiment is provided with a limiting column 114, and the suspension plate 19 is provided with a through hole 191. The lower end of the limiting column 114 passes through the through hole 191 and is provided with a blocking portion 1161. The through hole 191 can slide in the keyboard height direction Z relative to the limiting column 114, and the elastic pad 115 is sleeved on the limiting column 114 and pressed between the upper cover 11 and the suspension plate 19, and the spring 117 is sleeved on the limiting column 114 and pressed between the suspension plate 19 and the blocking portion 1161, so that the suspension plate 19 has elastic floating ability in the keyboard height direction Z relative to the upper cover 11, and the circuit on the suspension plate 19 The board 18 can be suspended on the upper cover 11 by the suspension board 19 in a flexible floating manner in the keyboard height direction Z. When the key 14 on the circuit board 18 is pressed downward, the key 14 transmits the impact force of pressing downward to the circuit board 18. At this time, the spring 117 pressed between the suspension board 19 and the blocking part 1161 is compressed and deformed, so that the key 14 has a soft and warm feel when it is tapped. Since the spring 117 itself has a certain rigidity, it can prevent the feel of the key 14 from being too soft and affecting the user's touch. Thus, while ensuring the elasticity of the touch of the key 14, the soft and warm feel of the key 14 is improved, thereby improving the user's experience. When the key 14 is released and reset, the spring 117 elastically resets, forcing the suspension board 19 to drive the circuit board 18 to reset upward in the keyboard height direction Z. Because there is an elastic pad 115 set pressed between the upper cover 11 and the suspension board 19, the elastic reset of the suspension board 19 is buffered, so as to ensure that the elastic reset performance of the suspension board 19 driving the circuit board 18 is stable and reliable. In addition, the rear end of the lower cover 17 of the adaptive soft-elastic keyboard 10 of the present embodiment is rotatably hinged to the rear end of the upper cover 11, and the lower cover 17 extends in a corresponding manner to the upper cover 11 in the keyboard width direction Y and the keyboard length direction X, respectively, so that the adaptive soft-elastic keyboard 10 as a whole can be placed flat on the support table, such as Fig.19 As shown, the adaptive soft-elastic keyboard 10 as a whole can also be supported vertically on a support table, such as Fig. 20 As shown, the adaptive soft-spring keyboard 10 of this embodiment can meet the different placement and usage requirements of users, thereby improving the user experience.

[0043] Therefore, the adaptive soft-elastic keyboard 10 of this embodiment rotatably hinges the rear end of the lower cover 17 with the rear end of the upper cover 11, and the angle adjustment between the upper cover 11 and the lower cover 17 can be achieved without the need for an additional adjustment stand, thereby simplifying the structure. In addition, the adaptive soft-elastic keyboard 10 of this embodiment can achieve a soft and warm feel of the keys 14 by setting a limit column 114 on the upper cover 11 and opening a through hole 191 on the suspension plate 19 to adapt to the elastic pad 115, the spring 117, and the blocking part 1161. The structure is simple and compact, thereby saving production costs. At the same time, the elastic life of the spring 117 is long, thereby delaying the service life of the keyboard. In addition, the adaptive soft-elastic keyboard 10 of this embodiment does not have a rigid collision, can eliminate the rigid collision noise, achieve the purpose of silencing, and enhance the user experience. In addition, the adaptive soft-elastic keyboard 10 of this embodiment can be selectively supported on a support table in a horizontal or vertical position, thereby meeting the different placement and use requirements of users, thereby enhancing the user experience.
