detailed description

The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings and preferred embodiments.

Embodiment 1:

Referring to FIG. 1 to FIG. 3, the embodiment provides an ultra-thin mechanical keyboard switch with a pressing sound, comprising a key cap 1, a cover 2, a guiding core 3 and a base 4 which are sequentially arranged from top to bottom, and the base 4 is provided with a conducting component 5 comprising a static contact piece 51 and a movable contact piece 52. The guiding core 3 is connected to the base 4 via a return spring 6, and the lower end surface of the cover 2 is provided with a balance bar In the group 7, the balance bar set 7 comprises an outer balance bar 71 and an inner balance bar 72. The base 4 is provided with an elastic member 8. Preferably, the elastic member 8 is a spring, and the elastic member 8 is The rear end is fixed to the base 4, and its front end projects below the balance bar group 7.

In this embodiment, the front end of the elastic member 8 has an elastic head 81, and the front end of the elastic head 81 is located at the edge of the lower end surface of the guiding core 3. The rear end of the elastic member 8 includes a hook-shaped elastic portion 82 and a spiral elastic portion 83 connected between the hook-shaped elastic portion 82 and the front end of the elastic member 8.

In this embodiment, the static contact piece 51 and the movable contact piece 52 have no pins and are directly attached to the PCB.

At the same time, a rubber sleeve 9 is disposed at the front end of the elastic member 8. When the elastic member 8 is attached with the rubber sleeve 9, there is a feeling and sound, and when the rubber sleeve 9 is not installed, there is no sound in the hand, and the switching between the sound and the sound is achieved.

The working principle of the embodiment is that after the keycap 1 is pressed, the key cap 1 presses the lead core 3, and during the downward movement of the guiding core 3, the guiding core 3 slides the elastic head 81 to press the elastic head 81 to move downward. a certain position; when the guiding core 3 is pressed down, the driving contact piece 52 is driven into contact with the static contact piece 51. At the same time, after the guiding core 3 is pressed down, the elastic head 81 is released from the guiding core 3 and is rebounded, and the cover 2 is knocked down. The end face emits a crisp sound, and when the keycap 1 is released, the guide core 3 is reset by the return spring 6.

The entire pressing stroke of the keyboard switch of this embodiment is 1.2 mm and the height is 2 mm, which is thinner than other mechanical keyboard switches. New elastic member 8 control, which increases the feel of the pressing and the sound, improves the hearing effect, and can achieve the sound with and without Switching the sound.

Embodiment 2:

Referring to FIG. 4 to FIG. 6 , the main difference between the embodiment and the embodiment is that the front end of the elastic head 81 ′′ is located at the inner lower edge of the balance bar group 7 . As an embodiment of the embodiment, the elastic head A first guiding slope 811 is provided on the 81"; as another embodiment of the embodiment, the balance bar group 7 is provided with a boss 73 in the inner side direction, and the boss 73 has a second guiding slope 731. Other structures are the same as those in the first embodiment, and are not described herein again.

The working principle of the embodiment is that after the key cap 1 is pressed, the key cap 1 presses the lead core 3, and the lead core 3 is pressed to contact the driving contact piece 52 to be in contact with the static contact piece 51, and at the same time, the key cap 1 is pressed and balanced. In the process of moving the balance bar group 7 downward, the balance bar group 7 slides the elastic head 81 to press the elastic head 81 downward to move to a certain position. When the balance bar group 7 is pressed, the elastic head 81 is out of balance. The rod group 7 is rebounded, and the lower end surface of the cover 2 is made to emit a crisp sound. When the keycap 1 is released, the balance rod group 7 is reset by the return spring 6. In the present embodiment, as one of the embodiments, when the keycap 1 presses the balance bar group 7, the first guide slope 811 on the elastic head 81" slides between the balance bar group 7 and the elastic head 81. Orientation; as another embodiment, when the keycap 1 presses the balance bar set 7, the balance bar set 7 slides the elastic head 81 with the second guide bevel 731, and the second guide bevel 731 pairs the balance bar set 7 and the elastic The sliding between the heads 81 serves as a guide.

The main point of the utility model is that the internal space of the keyboard switch is fully utilized, and by adding an elastic member in the keyboard switch, the keyboard switch can have a good tactile feeling during pressing under the premise that the keyboard switch is small and thin; Cooperating with the guiding core, or the elastic member and the guiding core balance rod group, the sound is generated during the pressing process of the keyboard switch, and the rubber sleeve design on the elastic member is combined to realize the switching between the sounding and the silent pressing, and the utility is greatly improved and improved. user experience.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention. Therefore, other structures obtained by the same or similar technical features as the above-described embodiments of the present invention are used. Within the scope of protection of the present invention.
