In some embodiments, as shown in fig. 1 to 3 and fig. 5 to 7, the buffer portion includes a first buffer portion 51 located between the motion portion 2 and the signal generating portion 3, and the adjusting from the first state action to the second state action includes:
The pressing force applied to the signal generating section 3 by the moving section 2 is adjusted from a first pressing force to a second pressing force, wherein the first pressing force is larger than the second pressing force.
Specifically, by the first buffer portion 51 disposed between the moving portion 2 and the signal generating portion 3, when the moving portion 2 moves to a certain position, the moving portion is contacted with the buffer portion 51 first, the moving speed of the first state is reduced to the moving speed of the second state, so that the pressing force of the moving portion 2 on the signal generating portion 3 is reduced, and further the reaction force of the signal generating portion 3 is reduced, that is, the reaction force fed back from the signal generating portion 3 to the finger of the user through the moving portion 2 and the bearing portion 1 is reduced, so that softer finger touch feedback is provided for the user, and a good touch experience can be realized even if the user knocks the keyboard with force each time of inputting information, and meanwhile, the user is prevented from using fatigue.
In some embodiments, the first buffer portion 51 is provided on the signal generating portion 3 and/or on a side of the moving portion 2 facing the signal generating portion 3. The first buffer unit 51 may be provided on the signal generating unit 3, the moving unit 2, or both the signal generating unit 3 and the moving unit 2, and may be provided between the signal generating unit 3 and the moving unit 2 so that the operating speed of the moving unit 2 from the first state is reduced to the second state, and the two may be prevented from directly contacting each other.
In some embodiments, the first buffer portion 51 includes a plurality of columnar structures disposed at intervals. On the one hand, the columnar structure has a certain thickness, so that a larger buffer space can be formed, the action speed of the moving part 2 can be effectively reduced, on the other hand, the first buffer part 51 is not required to be arranged at all the contact positions between the moving part 2 and the signal generating part 3, the first buffer part 51 is only arranged at the position where the moving part 2 and the signal generating part 3 are easy to interact, the moving part 2 can be ensured to provide enough pressing force for the signal generating part 3 to generate an input signal while the effective buffer is carried out, and the cost can be effectively reduced.
For example, in the present embodiment, the moving part 2 is a scissor type structure including two legs intersecting each other, and since the outer sides of the legs first contact the signal generating part 3 to act on the signal generating part 3, the first buffer part 51 is provided at a position where each leg of the scissor type structure is close to the outer side of the scissor type structure.
In other embodiments, the first buffer portion 51 may be an annular columnar structure, that is, the first buffer portion 51 is an integral structure, and the independent columnar structures are not required to be installed and positioned, so that the arrangement and the installation are convenient. The material of the first buffer portion 51 is preferably a soft rubber material.
In some embodiments, as shown in fig. 1 and 2, and fig. 5 and 6, the signal generating portion 3 is provided with a first hollow area 31, and an orthographic projection of the first buffer portion 51 on the signal generating portion 3 is located in the first hollow area 31.
The signal generating portion 3 has a first elasticity, and the first hollow-out area 31 is provided to form a deformation space (buffer space) when the first buffer portion 51 acts on the signal generating portion 3, so that the signal generating portion 3 can elastically deform, further buffer and reduce the action speed of the moving portion 2, and further provide a soft finger touch experience for a user.
In some embodiments, the signal generating part 3 is a thin film circuit board, and includes at least two thin film structures.
Illustratively, in this embodiment, the signal generating section 3 includes a first film layer 301, a second film layer 302, and a third film layer 303 that are stacked, where the first film layer 301 located at the top layer is a first circuit layer printed with a circuit, the second film layer 302 located at the middle layer is a middle layer without a circuit, and the third film layer 303 located at the bottom layer is a second circuit layer printed with a circuit. When the input device is in a first state (a free state as shown in fig. 1 and 5), the first circuit layer and the second circuit layer are separated by a middle layer, and the lines of the first circuit layer and the second circuit layer are not conducted; when the input device is in the second state (the pressed state as shown in fig. 1 and 5), the lines of the first circuit layer and the second circuit layer are turned on to generate an input signal.
In other embodiments, the signal generating section 3 may include only the first circuit layer and the second circuit layer, and similarly, when the input device is in the first state, the lines of the first circuit layer and the second circuit layer are not turned on; when the input device is in the second state, the lines of the first circuit layer and the second circuit layer are conducted to generate an input signal. In this embodiment, through setting up the intermediate layer, can keep apart upper and lower two-layer circuit, avoid when input device is in the first state, the circuit on first circuit layer and second circuit layer switches on, guarantees the accuracy of input device input.
In other embodiments, the signal generating part 3 may further include other thin film layers in order to achieve other functions, which are not particularly limited in the present disclosure. The thin film circuit board is preferably a flexible PET printed circuit board.
In some embodiments, the first hollow-out area 31 penetrates at least one film in a direction opposite to the application direction of the trigger force, so as to provide a sufficient deformation space for the elastic deformation of the top film.
Further, the first buffer portion 51 is disposed on the top film or between two adjacent films.
As shown in fig. 1 and 2, and fig. 5 and 6, when the first buffer portion 51 is disposed on the top film, the first hollow portion 31 may penetrate through other film layers (penetrating through the second film layer 302 and the third film layer 303) except the top film. The first buffer portion 51 may be disposed between the first film layer 301 and the second film layer 302, and at this time, the first hollow area 31 is disposed on the third film layer 303 to form a deformation space, so that the first buffer portion 51 is elastically deformed toward the third film layer 303.
In some embodiments, the fixing portion 4 is provided with a second hollow portion 41, and an orthographic projection of the first buffer portion 51 on the fixing portion 4 is located in the second hollow portion 41. The second hollow section 41 functions similarly to the first hollow section 31 and provides a certain deformation space for the signal generating section 3.
The fixing portion 4 is a metal plate structure, and the second hollow portion 41 may be coaxially disposed with the first hollow portion 31, so as to ensure elastic deformation of at least one thin film layer of the signal generating portion 3. The size of the second hollow area 41 may be smaller than the size of the first hollow area 31 to reliably fix the signal generating portion 3 while buffering. In this embodiment, as shown in fig. 4, one end of the moving part 2 may be mounted on the fixed part 4 by a mounting position 42 provided on the fixed part 4, and the other end of the moving part 2 is connected to the carrying part 1.
In some embodiments, the third hollow area 32 is disposed on the second film layer 302, so that on one hand, when the input device is in the second state, the first circuit layer and the second circuit layer are connected, and on the other hand, the volume of the second film layer 302 and the overall weight of the signal generating portion 3 can be reduced. The third hollowed-out area 32 may be disposed at a position corresponding to the center pivot of the moving part 2 of the scissor structure.
In some embodiments, as shown in fig. 1 and 4, the buffer portion includes a second buffer portion 52 provided on the moving portion 2, and the adjusting from the first state action to the second state action includes:
when the moving part 2 moves to a preset position along the application direction of the trigger force, the friction force born by the moving part 2 is adjusted from a first friction force to a second friction force, wherein the first friction force is smaller than the second friction force.
Specifically, the moving part 2 of the scissor structure comprises two supporting legs which are mutually crossed and matched, and when the input device is in a first state, a certain included angle is formed between the two supporting legs; when the input device is in the second state, the carrier 1 is pressed to the bottom, the two legs overlapping each other. That is, when the input device is not pressed, no interaction occurs between the two legs, and when the bearing part 1 is pressed, the moving part 2 moves to a certain position towards the signal generating part 3, the two legs at the upper side and the lower side interact, are compressed under the action of the bearing part 1, so that the included angle between the two legs is gradually reduced, and then can move to a position where the two legs overlap each other. In this embodiment, the second buffer portion 52 is disposed on one side of the two opposite legs, so that when the moving portion 2 moves to the preset position, the mutual friction between the two legs is increased, so that the motion of the moving portion 2 is adjusted from the first state motion to the second state motion, and the motion speed of the moving portion 2 is reduced, thereby realizing buffering. The above-mentioned preset position may be determined according to the structure, size, operation speed required to be reduced, etc. of the moving part 2.
In this embodiment, the second buffer portion 52 may be a wavy convex or concave portion provided on the leg, and its specific shape and length may be determined according to actual needs.
In some embodiments, as shown in fig. 4, the buffer portion further includes a third buffer portion 53 disposed on the signal generating portion 3 and located on one side of the moving portion 2, where the adjusting from the first state action to the second state action includes:
the trigger force received by the moving portion 2 is partially transferred to the third buffer portion 53.
That is, in the present embodiment, the trigger force applied to the moving portion 2 by the carrier portion is partially transferred to the third buffer portion 53, so that the operation speed of the moving portion 2 is reduced to thereby realize buffering. The third cushioning portion 53 is preferably an elastic member, such as an elastic silicone member, that provides a soft tactile experience to the user by utilizing the elastic cushioning effect of the elastic member.
In particular, in this embodiment, as shown in fig. 4, the third buffer portion 53 may be directly connected between the carrier portion 1 and the signal generating portion 3, so that when the moving portion 2 moves initially, the triggering force of the moving portion 2 can be dispersed, and as the moving portion 2 moves toward the signal generating portion 3, the triggering force of the moving portion 2 dispersed by the third buffer portion 53 gradually increases, the elastic force accumulated by the third buffer portion 53 gradually increases, and the movement speed of the moving portion 2 gradually decreases, so that when the moving portion 2 moves to the lowest position, the force fed back to the user by the moving portion 2 decreases, and when the triggering force disappears in cooperation with the movement of the moving portion 2 to the lowest position, the elastic force released by the third buffer portion 53 can provide a soft tactile experience for the user.
In this embodiment, the third buffer portion 53 may not be connected to the carrier portion 1, that is, one end of the third buffer portion 53 is connected to the signal generating portion 3, and the other end is a free end. When the movement of the moving part 2 toward the signal generating part 3 reaches a certain position, the bearing part 1 comes into contact with the third buffer part 53, so that the partial trigger force received by the moving part 2 is dispersed, the movement speed of the moving part 2 is reduced, and the buffer is realized.
In some embodiments, as shown in fig. 5 to 7, the buffer part further includes a buffer film 54 provided on the signal generating part 3, the buffer film 54 being located between the moving part 2 and the signal generating part 3. The movement of the first buffer portion 51 can be further buffered by the buffer film 54.
In this embodiment, the buffer film 54 may be integrally formed with the signal generating portion 3, that is, the buffer film 54 may be a top film of the signal generating portion 3. When the buffer film 54 is the top film of the signal generating portion 3, the first hollow portion 31 may sequentially penetrate through the third film layer 303, the second film layer 302 and the first film layer 301 from the bottom of the signal generating portion 3, that is, the first buffer portion 51 acts on the buffer film 54, so that the buffer film 54 may be elastically deformed in the first hollow portion 31.
The structure of the signal generating section 3 including the buffer film 54 may refer to the signal generating section 3 not including the buffer film 54 described above, and will not be described here.
In some embodiments, a fourth hollow area 541 is further provided on the buffer film 54 at a position not corresponding to the first buffer portion 51, so as to avoid interaction between the moving portion 2 and other positions on the buffer film 54, and to avoid excessive buffering while realizing soft touch experience, so that the signal generating portion 3 cannot generate an input signal, thereby improving performance of the input device.
In some embodiments, the input device further includes a backlight module 6, the backlight module 6 and the signal generating portion 3 are respectively disposed on two sides of the fixing portion 4, so as to fix the backlight module 6 and the signal generating portion 3 respectively, and after the signal generating portion 3 generates the input signal, the backlight module 6 can emit light to display, so that a user can view the corresponding key.
The embodiment of the disclosure also provides electronic equipment, which comprises the input device. The electronic device may be a notebook computer having an input device, or may be an electronic device such as a desktop computer (PC) or a tablet computer to which the input device can be connected. When the electronic equipment is a notebook computer, the key stroke of the input device can be set smaller, which is beneficial to the light and thin design of the electronic equipment; when the electronic equipment is a desk computer, the input device is used as an independent keyboard, and the key stroke of the input device can be set smaller, so that the input device is convenient for a user to carry.
