The upper cover 11 and the lower cover 14 are covered to form a limiting inner cavity 110. The upper cover 11 comprises an upper end plate 111 and a circumferential wall 112 arranged on the upper end plate 111. The floating plate 19 is movably arranged in the limiting inner cavity 110 in the normal direction of the upper end plate 111. The circuit board 120 is arranged on the lower side of the floating plate 19 in the normal direction of the upper end plate 111, and a plurality of keys 18 are arranged on the circuit board 120. The keystroke ends of the keys 18 are arranged to pass through the floating plate 19 and the upper end plate 111 in the normal direction of the upper end plate 111, and the keystroke ends of the keys 18 are arranged with keycaps 12. Among them, a plurality of elastic pads 122 are arranged on the inner end surface of the upper end plate 111 in the normal direction of the upper end plate 111 and are arranged at intervals in the circumferential direction of the upper end plate 111, the floating plate 19 can be pressed against the elastic pad 122, and a plurality of elastic members are arranged at intervals in the circumferential direction of the circumferential wall 112 in the limiting inner cavity 110, and the two ends of each elastic member are respectively connected between the inner circumferential surface of the circumferential wall 112 and the outer periphery of the floating plate 19 or the outer periphery of the circuit board 120, so that the floating plate 19 or the circuit board 120 is tensioned by the elastic member to be kept parallel to the upper end plate 111. In addition, the plurality of elastic members are composed of one or more of an elastic drawstring, an elastic drawstring, an elastic cloth, and an elastic tension spring. Among them, the normal direction of the upper end plate 111 is the direction perpendicular to the upper end plate 111.

[0039] The floating plate 19 of the trampoline-type soft spring keyboard 10 of the present embodiment is movably arranged in the limit inner cavity 110 formed by the upper cover 11 and the lower cover 14 in the normal direction of the upper end plate 111, and the circuit board 120 is arranged on the lower side of the floating plate 19 in the normal direction of the upper end plate 111. A plurality of elastic members are arranged in the limit inner cavity 110 at intervals in the circumferential direction of the circumferential wall 112, and the two ends of each elastic member are connected between the inner circumferential surface of the circumferential wall 112 and the outer periphery of the floating plate 19 or the outer periphery of the circuit board 120, so that the floating plate 19 or the circuit board 120 is tensioned by the elastic member to be kept parallel to the upper end plate 111, so that the floating plate 19 and the circuit board 120 form a trampoline-like movement in the normal direction of the upper end plate 111. When the keycap 12 is pressed downward in the normal direction of the upper end plate 111 to force the key 18 on the circuit board 120 to move, the key 18 transmits a downward pressing impact force to the circuit board 120. At this time, multiple elastic parts elastically deform and tension to keep the floating plate 19 or the circuit board 120 moving downward in parallel with the upper end plate 111, so that the key 18 has a soft and elastic feel when struck, avoiding the key 18 from being too soft or hard to affect the user's touch, thereby improving the comfort of the soft and elastic feel of the key 18 and further enhancing the user experience. When the keycap 12 is loosened to reset the key 18, multiple elastic members elastically reset and tension the floating plate 19 or the circuit board 120 to move upward and reset in parallel with the upper end plate 111. Since multiple elastic pads 122 are provided on the inner end surface of the upper end plate 111, the floating plate 19 is pressed against the elastic pad 122 after resetting, thereby buffering the elastic reset of the floating plate 19, so as to ensure that the elastic reset performance of the floating plate 19 driving the circuit board 120 is stable and reliable. Compared with the existing elastic parts that are arranged at one end or both ends of the circuit board module in the up and down directions of keycap tapping, there are problems of limited elasticity and travel. The two ends of each elastic part of the trampoline-type soft-spring keyboard 10 of this embodiment are connected between the inner circumferential surface of the circumferential wall 112 and the outer periphery of the floating plate 19 or the outer periphery of the circuit board 120, so that the floating plate 19 or the circuit board 120 is tensioned by the elastic parts to keep it parallel to the upper end plate 111, which can increase the trampoline-like elastic movement travel of the floating plate 19 and the circuit board 120 in the normal direction of the upper end plate 111, thereby improving the comfort of the soft and springy feel of the key 18.
