Therefore, the problem that in the related art, the size of the remote controller is large, the holding posture of a user needs to be frequently changed in the process of using the remote controller, and the user use experience is affected can be solved.

The second key 220 may correspond to one key function, or the second key 220 may include a plurality of pressing portions 221, and pressing each pressing portion 221 may trigger a corresponding key function, so that the second key 220 corresponds to a plurality of key functions.

In this case, the deformation and deformation recovery processes of the first elastic element 250 can provide a stable moving stroke for the first key 210 or the pressing portion 221, and the key assembly 200 can be connected to the housing 100 through the cooperation of the first hook 240 and the second hook 114, and the connection stability is good, so that the key assembly 200 can be prevented from being separated from the housing 100.

The first elastic member 250 may be an elastic column or a spring, and the first elastic member 250 may be directly disposed on each of the first keys 210 or the pressing portion 221.

For this reason, in the embodiment of the present application, the remote controller may further include a circuit board assembly 300, the housing 100 may be provided with an accommodating cavity, the circuit board assembly 300 may be provided in the accommodating cavity, and a surface of the circuit board assembly 300 facing the key assembly 200 may have a plurality of snap tabs 330.

In this case, compared with the technical scheme that the second elastic member 260 is a rigid structural member, the second elastic member 260 has elasticity, so that the contact between the second elastic member 260 and the metal dome 330 is elastic contact, and the metal dome 330 is protected.

The first key 210 may be provided with two first hooks 240 and a second elastic member 260, and the two first hooks 240 and the second elastic member 260 may be located on a central line a of the first key 210, where the central line a of the first key 210 passes through an arc center of an arc where the first key 210 is located. The second key 220 may be provided with two first hooks 240 and four second elastic members 260, the four second elastic members 260 may be distributed at intervals of 90 ° and respectively correspond to the four pressing portions 221, and for pressing, the second elastic members 260 on the second key 220 may be adjacent to an edge of the second key 220.

When the first key 210 or the pressing portion 221 is pressed, the first elastic member 250 is deformed into the first key 210 or the pressing portion 221 to provide a stable moving stroke, the second elastic member 260 moves towards the direction close to the metal dome 330 along with the first elastic member 250, the second elastic member 260 continues to move to press the metal dome 330, when the pressing force of the second elastic member 260 pressing the metal dome 330 exceeds the operation starting force of the metal dome 330, the metal dome 330 is deformed under stress, the metal dome contact 331 is in contact with the second copper exposure 312 to form a conducting circuit, so that an electrical signal flows from the first copper exposure 311 to the second copper exposure 312 along the metal dome 330 from the metal dome contact 331, an effective electrical signal is formed and is transmitted to a chip in the second circuit board 320, the chip identifies the electrical signal and processes the electrical signal, and a corresponding key function is realized.

Referring to fig. 13 again, the snap dome 330 may be an arc-shaped metal spring, and under the action of the pressing force, the snap dome contact 331 deforms to contact the second copper exposure 312 in the first circuit board 310, so as to conduct the first copper exposure 311 and the second copper exposure 312, so that the snap dome 330 of the circuit board assembly 300 is conducted to the circuit, and an electrical signal is generated.

The operating start force of the snap dome 330 may be 130gf, the operating height (displacement perpendicular to the direction of the first circuit board 310, which is generated after the snap dome 330 receives a pressing force) may be 0.27mm, the pressing force for pressing the first button 210 or the pressing portion 221 needs to overcome the reverse thrust generated by the deformation of the first elastic member 250 and the second elastic member 260, and the range of the pressing force for pressing the first button 210 or the pressing portion 221 is 150gf-180gf.

The number of the snap rings 330 may be equal to the total number of the first keys 210 and the pressing portions 221, and may correspond to one another, for example, in a case where the number of the first keys 210 is 9, and the number of the pressing portions 221 is 4, the number of the snap rings 330 may be 13.

In order to signal that the first key 210 or the pressing portion 221 is effectively pressed, the first circuit board 310 may further have an indicator light, and when the metal dome 330 of the first circuit board 310 operates to form an electrical signal, the chip processes the electrical signal to control the indicator light to flash, so as to indicate that the key is effectively pressed. The housing 100 may be formed with a third communication hole 117 facing the indicator, and the first button 210 and the second button 220 avoid the third communication hole 117, so that light emitted from the indicator can leak out of the housing 100.

Further, a light guide column can be arranged between the indicator light and the third communication hole 117, so that light emitted by the indicator light is transmitted to the outside of the casing 100 through the light guide column, the part of the light guide column can extend into the third communication hole 117 and is connected to the hole wall of the third communication hole 117 in a hot melting mode, the outer wall of the light guide column and the hole wall of the third communication hole 117 can be in sealing fit, and external sundries are prevented from entering the casing 100 through the third communication hole 117 or falling into the circuit board assembly 300, so that the circuit board assembly 300 is short-circuited and the like.
