As shown in fig. 1-5, a key assembly according to some embodiments of the present application includes:
the device comprises a support 4, wherein a first elastic thimble 21 and a second elastic thimble 22 are arranged on the support 4. The first elastic thimble 21 and the second elastic thimble 22 are elastic thimbles.
A key cap 3, a first end of said key cap 3 being adjacent to the support 4, the first end comprising a conductor contact and an insulating contact 313. With the key cap 3 in the first position, the first and second resilient pins 21, 22 are in contact with the conductor contact portion. When the key cap 3 is at the second position, the first elastic thimble 21 is in contact with the conductor contact portion, and the second elastic thimble 22 is in contact with the insulation contact portion 313.
In the present embodiment, the conductor contact portions include a first conductor contact portion 311 and a second conductor contact portion 312.
When the key cap 3 is located at the first position, the first elastic thimble 21 contacts with the first conductor contact portion 311, and the second elastic thimble 22 contacts with the second conductor contact portion 312.
With the key cap 3 in the second position, the first resilient pin 21 contacts the second conductor contact 312, and the second resilient pin 22 contacts the insulating contact 313.
In the embodiment of the application, by controlling the key cap 3 to switch between the first position and the second position, the first elastic thimble 21 and the second elastic thimble 22 are contacted with different ones of the first conductor contact part 311, the second conductor contact part 312 and the insulating contact part 313, so as to control the corresponding functions to be turned on or turned off. This key assembly's simple structure, elasticity thimble can ensure more reliable and more stable with the contact of key cap 3.
The end portions of the first elastic thimble 21 and the second elastic thimble 22 are elastic and can stretch, so that the first elastic thimble 21 and the second elastic thimble 22 can have enough pressure with the keycap 3 to ensure the reliability of contact. It is understood that the resilient ejector pins in the present application include, but are not limited to, pogo pins.
The second elastic thimble 22 and the second elastic thimble 22 are in different contact positions by moving the key cap 3, so as to change the contact object of the first elastic thimble 21 and the second elastic thimble 22.
The first conductor contact portion 311 and the second conductor contact portion 312 are made of a conductor material, and the insulating contact portion 313 is made of an insulating material. When the key cap 3 is located at the first position, the first elastic thimble 21 and the second elastic thimble 22 are both in contact with the conductor contact portion made of the conductor material. When the key cap 3 is located at the second position, the first elastic thimble 21 contacts with the second conductor contact portion 312 made of a conductor material, and the second elastic thimble 22 contacts with the insulating contact portion 313 made of an insulating material. When the key cap 3 is located at the first position and the second position, the contact material of the first elastic thimble 21 and the second elastic thimble 22 changes, so that different electric signals are generated according to the change of the contact material, and the function of the electronic device is controlled to be turned on or turned off through the key cap 3.
The electronic equipment is provided with a first elastic thimble 21 and a second elastic thimble 22, the two elastic thimbles are in contact with the keycap 3 and form stable support for the keycap 3, and the structure that the first elastic thimble 21 and the second elastic thimble 22 are matched with the keycap 3 is simple. And the reliability of the contact between the first elastic thimble 21 and the second elastic thimble 22 and the key cap 3 is higher, and the difference of the contact between the conductor material and the insulating material and the elastic thimble is obvious, thereby effectively ensuring the reliability of the signal change generated when the key cap 3 is switched between the first position and the second position.
In one embodiment, the first conductor contact 311 and the second conductor contact 312 are metallic materials.
The metal material can be a conductor metal with better conductivity, so as to improve the contact conductivity between the first conductor contact part 311 and the second conductor contact part 312 and the elastic thimble. And the metal material has excellent extensibility and can be processed into a structure matched with the elastic thimble more easily.
Optionally, the first conductor contact portion 311 and the second conductor contact portion 312 are integrally formed, so as to reduce the manufacturing difficulty and cost.
Optionally, the insulating contact portion 313 is at least one of plastic, rubber, ceramic and glass.
Plastic, rubber, ceramic and glass all have an insulating effect, and can effectively contact the second elastic thimble 22 to the insulating region.
In one embodiment, the insulating contact 313 is injection molded onto the key cap 3.
The insulating contact part 313 is made of insulating materials, and the insulating contact part 313 is arranged on the keycap 3 in an injection molding mode, so that the structural strength of the insulating contact part 313 is improved. For example, an injection molded part 30 is injection molded on the key cap 3, and the injection molded part 30 has an insulating contact part 313 on a side close to the support 4.
In one embodiment, at least one of the first conductor contact portion 311, the second conductor contact portion 312 and the insulation contact portion 313 is provided with a concave portion, and contacts the first elastic thimble 21 or the second elastic thimble 22 through an inner surface of the concave portion.
In this embodiment, the concave portion can improve the limiting effect when the elastic thimble is in contact, and improve the reliability of the contact fit between the elastic thimble and the keycap 3. For example, the first elastic thimble 21 is in contact with the inner surface of the recess, and the structure of the recess can maintain the stability of the contact fit of the first elastic thimble 21 and the key cap 3. Similarly, when the second elastic thimble 22 contacts the inner surface of the concave portion, the stability of the contact engagement of the second elastic thimble 22 with the key top 3 can be improved.
In one embodiment, the key cap 3 is slidably disposed on one side of the support 4, the first conductor contact 311 has a first recess, the second conductor contact 312 has a second recess, and the insulation contact 313 has a third recess.
When the key cap 3 is located at the first position, the end of the first elastic thimble 21 is in contact with the inner wall of the first concave part, and the end of the second elastic thimble 22 is in contact with the inner wall of the second concave part; when the key cap 3 is located at the second position, the first elastic thimble 21 contacts with the inner wall of the second concave portion, and the second elastic thimble 22 contacts with the inner wall of the third concave portion.
In this embodiment, the key cap 3 is switched between the first position and the second position, so that the first elastic thimble 21 and the second elastic thimble 22 can be in contact fit with corresponding recesses in the first recess, the second recess, and the third recess, which can effectively improve the stability of the contact between the first elastic thimble 21 and the second elastic thimble 22 and the key cap 3, and improve the reliability of the key assembly.
For example, during the process of switching the key cap 3 from the first position to the second position, the first elastic thimble 21 and the second elastic thimble 22 move synchronously. The first elastic thimble 21 moves from the first concave portion to the second concave portion, and the second elastic thimble 22 moves from the second concave portion to the third concave portion.
The end of the elastic thimble can extend and contract, for example, when the first elastic thimble 21 moves out of the first concave portion in the process of moving from the first concave portion to the second concave portion, the end of the first elastic thimble 21 is compressed, and when the first elastic thimble 21 moves into the second concave portion, the end of the first elastic thimble 21 is extended. The second elastic pin 22 moves in the same manner as the first elastic pin 21.
Optionally, the concave portion is a groove with an arc-shaped cross section, and the arc shape is matched with the end portions of the first elastic thimble 21 and the second elastic thimble 22, so that the contact reliability of the elastic thimbles and the keycap 3 is improved. And the inner surface of the groove with the arc-shaped section is smoother, so that the elastic thimble moves more easily, and the concave part is prevented from generating overlarge obstruction to the movement of the elastic thimble. The elastic thimble is smoother when being separated from or entering the groove with the arc-shaped cross section, so that the keycap 3 is smoother to switch between the first position and the second position.
In one embodiment, the first conductor contact 311 and the second conductor contact 312 abut. During the process of switching the key cap 3 between the first position and the second position, the first elastic thimble 21 keeps in contact with one of the first conductor contact part 311 and the second conductor contact part 312. The second resilient thimble 22 is held in contact with one of the second conductor contact portion 312 and the insulating contact portion 313.
And/or a smooth transition connection between the surface of the first conductor contact 311 near the support 4, the surface of the second conductor contact 312 near the support 4, and the surface of the insulating contact 313 near the support 4. The smooth transition enables the first elastic thimble 21 and the second elastic thimble 22 to move more smoothly in the process of switching the key cap 3 between the first position and the second position.
In this embodiment, during the switching of the key cap 3 between the first position and the second position, the first elastic thimble 21 moves between the first conductor contact portion 311 and the second conductor contact portion 312. The second resilient thimble 22 moves between the second conductor contact 312 and the insulation contact 313.
The concave part and the elastic thimble are matched to ensure that the keycap 3 has more stable contact under the condition of being positioned at the first position or the second position, and the surfaces are smoothly transited to ensure that the elastic thimble moves more smoothly relative to the keycap 3.

In this embodiment the key cap 3 is exposed to the first opening 12, and the user moves the key cap 3 through the second end of the key cap 3. The key cap 3 is slid with respect to the housing 1 by pushing the key cap 3, so that the key cap 3 is switched between the first position and the second position.
In one embodiment, the casing 1 is provided with a mounting cavity for accommodating the key assembly, and the mounting cavity is communicated with the first opening 12.
In this embodiment, the key assembly is disposed in the mounting cavity such that the second end of the key cap 3 is exposed to the first opening 12.
In one embodiment, the housing 1 is provided with a second opening 13 communicating with the mounting cavity, and the bracket 4 is disposed in the mounting cavity through the second opening 13.
In this embodiment, the bracket 4 can be fitted into the mounting cavity through the second opening 13, so that the first elastic thimble 21 and the second elastic thimble 22 are in contact fit with the key cap 3. For example, the key cap 3 is first assembled into the mounting cavity, and then the frame 4 is installed through the second opening 13, such that the first elastic pin 21 and the second elastic pin 22 are engaged with the first end of the key cap 3.
The elastic thimble can be extended and contracted, and the support 4 can be smoothly loaded from the second opening 13 by compressing the elastic thimble. For example, the elastic pin is tilted, the end of the elastic pin is pressed against the inner side of the second opening 13, and the elastic pin is compressed to mount the holder 4 and the mounting cavity.
Optionally, a third opening 11 is further disposed on the housing, and the third opening 11 and the first opening 12 are located on two sides away from each other.

After the support 4 is placed into the installation cavity, the inner walls of the two sides of the third opening 11 can limit the support 4, so that the stability of the structure of the support 4 is guaranteed.
For example, the first opening 12 is located outside the housing 1, the third opening 11 is located inside the housing 1, and the length of the third opening 11 is smaller than that of the second opening 13, so that the third opening 11 occupies a smaller space, the space occupied by the third opening 11 is reduced, and more space is left for the inside of the housing 1 for mounting internal components of the electronic device.

The first member 31 is configured to form a sliding structure with the housing 1 so that the key cap 3 can move to be switched between the first position and the second position. For example, a part of the structure of the second member 32 is exposed to the outside of the housing 1. The user moves the first member 31 by controlling the second member 32, thereby enabling the key cap 3 to switch between the first position and the second position.
The first conductor contact portion 311, the second conductor contact portion 312, and the insulating contact portion 313 are located on the first member 31.

For example, as shown in fig. 5, when the key cap 3 moves from the first position to the second position, the first conductor contact portion 311 is separated from the first elastic thimble 21, and the second conductor contact portion 312 is separated from the second elastic thimble 22. In this process, the first resilient thimble 21 moves toward the second conductor contact portion 312, and the second resilient thimble 22 moves toward the insulating contact portion 313. When the key cap 3 moves to the second position, the second elastic thimble 22 contacts the insulating contact portion 313, and the first elastic thimble 21 contacts the second conductor contact portion 312.
Optionally, a projection plane of the first member 31 on the plane of the first opening 12 covers the first opening 12, so that the first member 31 can be located in the installation cavity, the first member 31 abuts against an end face of the first opening 12 on which one opening is located, and the second member 32 extends into the first opening 12 and is exposed to the outside of the housing 1 through the first opening 12.

Alternatively, the key cap 3 is placed into the mounting cavity through the third opening 11, as shown for example in fig. 2-4.
The support 4 is placed into the mounting cavity through the second opening 13, as shown in fig. 3, after the support 4 is placed into the mounting cavity, the support 4 is located inside the second opening 13, so that the first elastic thimble 21 and the second elastic thimble 22 are engaged with the keycap 3.
For example, the bracket 4 is fixed in the mounting cavity by screws, mounting holes are provided at mounting positions of the bracket 4, and the screws are engaged with the mounting holes to fix the bracket 4.
Optionally, the second opening 13 is located on a third side adjacent to the side where the first opening 12 is located and the side where the third opening 11 is located. The keycap 3 is firstly placed into the installation cavity through the third opening 11, and then the support 4 is placed into the installation cavity through the second opening 13. After the first elastic thimble 21 and the second elastic thimble 22 are matched with the keycap 3, the bracket 4 is fixed.
The electronic equipment is simple in structure, the first elastic thimble 21 and the second elastic thimble 22 support the keycap 3 to form two point positions, and the structural stability is improved.

In one embodiment, the electronic device further includes a circuit board 5, and the first elastic thimble 21 and the second elastic thimble 22 are electrically connected to the circuit board 5. By providing a control circuit connected to the first elastic thimble 21 and the second elastic thimble 22, the key cap 3 can output different electrical signals when in the first position and the second position. So as to be capable of sending different control signals by controlling the keycap 3 to switch between the first position and the second position, and controlling the opening or closing of the corresponding function of the keycap 3.
When the first elastic thimble 21 and the second elastic thimble 22 are conducted by simultaneously contacting the conductor contact portion, the key assembly feeds back the first switch information to the circuit board 5. When the first elastic thimble 21 is conducted by contacting the conductor contact portion and the second elastic thimble 22 is not conducted by contacting the insulation contact portion 313, the key assembly feeds back the second switch information to the circuit board 5.
For example, the first conductor contact portion 311 and the second conductor contact portion 312 are conducted, so that the first elastic spike 21 and the second elastic spike 22 can form a loop. When the second elastic thimble 22 contacts the insulating contact portion, the circuit between the first elastic thimble 21 and the second elastic thimble 22 is broken.
The elastic thimble is internally provided with a spring, so that when the elastic thimble is contacted with the keycap 3, the elastic thimble can be compressed and rebounded along with the shape change of the keycap.
