As shown in fig. 1 to 3, the electronic device according to the first embodiment of the present utility model may specifically include: the device comprises a frame body 1, a pressure sensing element 2, a spring plate 3 and a key cap 4; the frame body 1 is provided with a groove 101, and the key cap 4 is movably arranged in the groove 101; the pressure sensing element 2 is embedded in the frame body 1; the spring plate 3 is accommodated in the groove 101 and is positioned between the keycap 4 and the pressure sensing element 2; the spring plate 3 is used for transmitting the pressing force on the key cap 4 to the pressure sensing element 2 and providing tactile feedback to the key cap 4.

According to the electronic device of the first embodiment of the present utility model, the key cap 4 is pressed towards the elastic sheet 3, the elastic sheet 3 deforms after receiving the pressing force of the key cap 4, and transmits the pressing force to the pressure sensing element 2 to trigger the pressure sensing element 2, so as to trigger the key function of the electronic device, and meanwhile, the elastic sheet 3 also provides touch feedback for the key cap 4 when receiving the pressing force of the key cap 4 to deform, so that a user obtains the touch feedback in the use process, and the user experience is improved. In addition, because the elastic sheet 3 only plays roles of providing mechanical touch feedback and transmitting force to the pressure sensing element 2, no electric connection function exists, and meanwhile, the pressure sensing element 2 is embedded in the frame body 1 and is tightly connected with the frame body 1, sweat cannot enter the pressure sensing element 2, and therefore, even if liquid enters the key cap 4, the key function of the electronic equipment is not affected.

It should be noted that, the spring plate in the conventional tact switch is a loop component in the electronic device circuit, and the spring plate is deformed by pressing the spring plate to realize the conduction of the circuit, but under long-time use, liquid entering the key cap can occur to wet the connection part between the spring plate and the circuit, so that the circuit is short-circuited, and the key function of the electronic device is disabled.

In the embodiment of the application, the electronic device is provided with a circuit board, the pressure sensing element 2 is electrically connected with the circuit board, the elastic sheet 3 has no electrical connection function, and has no electrical connection relation with the circuit board, and the elastic sheet 3 only transmits acting force from the key cap 4 to the pressure sensing element 2 when the key cap 4 is pressed to trigger the pressure sensing element 2, and the pressure sensing element 2 feeds back signals to the circuit board, so that the key function of the electronic device is triggered.

In the embodiment of the present application, the pressure sensing element 2, which is a main device for signal receiving and converting, may be a pressure sensor. In the use process, the keycap 4 is pressed towards the elastic sheet 3, so that the elastic sheet 3 deforms after being pressed, and a certain deformation amount of the elastic sheet 3 is required to be generated to trigger the pressure sensing element 2, and a certain deformation amount of the elastic sheet 3 is required to be generated to be achieved by applying a certain acting force to the elastic sheet 3 by the keycap 4; meanwhile, the resistance of the elastic sheet 3 to the keycap 4 and a certain deformation amount generated by the elastic sheet 3 provide tactile feedback for a user.

Optionally, the bottom of the groove 101 is provided with a first accommodating groove 1012, the pressure sensing element 2 is embedded in the first accommodating groove 1012, and the orthographic projection of the elastic sheet 3 on the bottom of the groove 101 at least partially coincides with the orthographic projection of the pressure sensing element 2 on the bottom of the groove 101. By pressing the key cap 4 toward the spring plate 3, the spring plate 3 deformed can be directly pressed against the pressure sensing element 2, i.e. a force is directly applied to the pressure sensing element 2 to trigger the pressure sensing element 2.

Optionally, the spring plate 3 includes an arc segment 31 and an edge segment 32 disposed around the arc segment 31, the arc segment 31 protrudes toward the keycap 4, and the edge segment 32 is movably disposed at the bottom of the groove 101. The arcuate sections 31 and the edge sections 32 of the dome 3 are shaped such that when the dome 3 is pressed by the key cap 4, a deformation amount sufficient to provide tactile feedback is achieved and a force sufficient to trigger the pressure sensing element 2 is transmitted to the pressure sensing element 2.

Alternatively, the pressure-sensitive element 2 has a protrusion 21, the protrusion 21 being accommodated in the recess 101 and protruding towards the dome 3, in particular, the protrusion 21 may protrude towards the arcuate section 31 of the dome 3. By providing the protrusion 21 on the pressure sensing element 2, the distance between the spring plate 3 and the pressure sensing element 2 is set, that is, the spring plate 3 can abut against the pressure sensing element 2 when a small deformation amount is generated, and tactile feedback can be provided to the keycap 4.

Optionally, a fixing frame 5 is arranged at the bottom of the groove 101, and the elastic sheet 3 is connected to the fixing frame 5.

Based on the elastic sheet 3, the elastic sheet 3 can expand towards the fixing frame 5 in the process of deformation when being pressed by the keycap 4, so that the arrangement of the first accommodating groove 1012 provides an accommodating space for the expansion of the elastic sheet 3, and the elastic sheet 3 is not offset or blocked from deformation when being pressed.

Further, the first limiting groove 501 is disposed on the inner peripheral surface of the annular body 503 and is connected to the bottom of the groove 101, so that when the key cap 4 presses the elastic sheet 3, a part of the edge section 32 contacts with the bottom of the groove 101, and another part of the edge section 32 contacts with the pressure sensing element 2.

As shown in fig. 3, according to still another embodiment of the present utility model, the fixing frame 5 includes a plurality of fixing blocks 504 spaced around the elastic sheet 3, i.e., the plurality of fixing blocks 504 are spaced around the first receiving groove 1012; the surface of the fixing block 504 facing the spring plate 3 is provided with a second limiting groove 502, and the edge section 32 is movably accommodated in the second limiting groove 502. The fixing frame 5 is provided in the form of a plurality of fixing blocks 504, so that the material consumption and the occupied space of the fixing frame 5 can be reduced.

It should be noted that, in this embodiment, the specific shape of the fixing frame 5 is not limited, but the fixing frame 5 needs to have a certain fixing effect on the elastic sheet 3, and meanwhile, a certain accommodating space is provided for deformation and expansion of the elastic sheet 3.

By providing the flange 42 on the key cap 4, the limit portion 1011 is provided inside the groove 101 of the frame body 1, which not only limits the movement travel of the key cap 4 in the groove 101, but also ensures that the key cap 4 does not fall off from the frame body 1.

According to other configurations of the electronic device of the embodiment of the present utility model, for example, an elastic member disposed in the groove 101 of the frame 1, the elastic member provides a resilience force to the keycap 4, so that the keycap 4 moves away from the elastic sheet 3 and moves to the first position; while pressing the key cap 4, the elastic member is pressed, the key cap 4 moves towards the spring plate 3 and to the second position, which is known to those skilled in the art, and will not be described in detail here
