Embodiments and features of embodiments in this application may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

First aspect

An embodiment of the present application provides a touch assembly, referring to fig. 1 to 5, the touch assembly includes: the touch panel 11, the spring sheet 12 and the electromagnetic structure 13, the touch panel 11 has a first surface 111 and a second surface 112 opposite to each other, and the first surface 111 of the touch panel 11 includes: touch area 1111 and press area 1112, shell fragment 12 set up in touch panel 11's second surface 112 side, and shell fragment 12 at least part is relative with press area 1112, and shell fragment 12 corresponds the part of press area 1112 and can be to the direction activity of being close to touch panel 11, and electromagnetic structure 13 sets up in shell fragment 12 one side that deviates from touch panel 11, and electromagnetic structure 13 corresponds with press area 1112, after electromagnetic structure 13 circular telegram, and partial electromagnetic structure 13 moves in the direction of shell fragment 12 in order to promote shell fragment 12 to the direction of touch panel 11 and move and support and touch panel 11.

Specifically, the touch pad 11 has a first surface 111 and a second surface 112 opposite to each other, and when the touch assembly is disposed on an electronic device (such as a notebook computer, which will be described below as an example), the first surface 111 is exposed from the outside of the electronic device, and the second surface 112 is correspondingly disposed inside the electronic device. The first surface 111 of the touch panel 11 described above includes: a touch area 1111 and a pressing area 1112, where a user can perform a touch operation in the touch area 1111 to control movement of a pointer on an electronic device where the touch assembly is located, and a user can perform a pressing operation in the pressing area 1112 to input information to the electronic device where the touch assembly is located, where the user performs a touch operation in the touch area 1111 may refer to movement operation of a mouse, and the user performs a pressing operation in the pressing area 1112 may refer to pressing operation of left and right keys of the mouse.

The spring 12 is disposed on the second surface 112 side of the touch panel 11, at least a portion of the spring 12 is opposite to the pressing area 1112, and a portion of the spring 12 corresponding to the pressing area 1112 can move in a direction close to the touch panel 11, that is, the spring 12 is disposed in the electronic device, and a portion of the spring 12 corresponding to the pressing area 1112 can move, and after a portion of the spring 12 corresponding to the pressing area 1112 moves, a distance between a portion of the spring 12 corresponding to the pressing area 1112 and the touch panel 11 is reduced, so when a user mistakenly presses the pressing area 1112, the spring 12 can move in a direction of the pressing area 1112 and prop against the touch panel 11 corresponding to the pressing area 1112, thereby preventing the portion of the touch panel 11 corresponding to the pressing area 1112 from being pressed down.

The electromagnetic structure 13 is disposed at one side of the spring 12 away from the touch panel 11, the electromagnetic structure 13 corresponds to the pressing area 1112, after the electromagnetic structure 13 is energized, a portion of the electromagnetic structure 13 can move towards the direction of the spring 12 to push the spring 12 to move towards the direction of the touch panel 11 and contact the touch panel 11, that is, the electromagnetic structure 13 can provide a driving force for the spring 12 to drive a portion of the spring 12 corresponding to the pressing area 1112 to move towards the direction close to the touch panel 11.

In the present embodiment, the spring 12 is disposed below the touch panel 11 and opposite to the pressing area 1112 of the touch panel 11, and the electromagnetic structure 13 can apply a partial driving force to the pressing area 1112 corresponding to the spring 12 so that the pressing area 1112 is blocked by the portion of the spring 12 corresponding to the pressing area 1112 from being pressed. In this way, when the pressing area 1112 of the touch pad 11 is pressed by mistake, the electromagnetic structure 13 gives the driving force to the elastic sheet 12, so that the part of the elastic sheet 12 corresponding to the pressing area 1112 blocks the pressing area 1112 from being pressed, thereby reducing the probability that the user presses the pressing area 1112 by mistake in the process of using the keyboard, and further reducing the probability that the pressing area 1112 is pressed by mistake to input error information to the electronic device where the touch assembly is located.

In some embodiments, referring to fig. 1 to 3, the electromagnetic structure 13 includes: the electromagnet 131 and the magnet 132, wherein one side of the electromagnet 131, which is close to the elastic sheet 12, is sunken with a containing concave part, and the magnet 132 is arranged in the containing concave part; the electromagnet 131 can be connected to a power supply device, and when the power supply device energizes the electromagnet 131, the magnet 132 moves in the direction of the spring piece 12.

Specifically, the electromagnet 131 is recessed on the side near the spring plate 12, and the recess may be a cylindrical recess, a rectangular recess, or another recess. The magnet 132 is disposed in the accommodating recess, and the shape and size of the magnet 132 may or may not be identical to those of the accommodating recess, for example: as shown in fig. 1 to 3, the shape and size of the magnet 132 are consistent with those of the accommodating recess, so that when the magnet 132 is disposed in the accommodating recess, there is no gap between the magnet 132 and the accommodating recess, thereby improving the aesthetic appearance of the electromagnetic structure 13. The electromagnet 131 can be connected to a power supply device, and when the power supply device energizes the electromagnet 131, the magnet 132 moves in the direction of the spring 12, for example: in the initial state, the magnet 132 and the electromagnet 131 are attracted to each other and are located in the accommodating recess, when the pressing area 1112 of the touch panel 11 is pressed by mistake, the power supply device supplies power to the electromagnet 131, and a repulsive force is generated between the electromagnet 131 and the magnet 132, so that the magnet 132 moves towards the direction of the spring plate 12 to push the spring plate 12 to contact the touch panel 11, and when the force of the mistakenly pressing is removed, the power supply device stops supplying power to the electromagnet 131.

In some embodiments, referring to fig. 1-3, the inner wall profile of the receiving recess is cylindrical and the shape of the magnet 132 is also cylindrical. In this way, the shape of the magnet 132 is similar to that of the accommodating recess, so that the accommodating recess and the magnet 132 have similar beauty, and the visual effect of the electromagnetic structure 13 can be improved.

In some embodiments, the magnets 132 are permanent magnet structures. In this way, the magnet 132 can ensure the maximum magnetic energy and stable magnetic property, so that the repulsive force between the magnet 132 and the electromagnet 131 can be improved, and the magnet 132 can drive the spring plate 12 to move and abut against the touch panel 11.

In some embodiments, referring to fig. 4 and 5, the pressing area 1112 includes: the first pressing area 1113 and the second pressing area 1114, the first pressing area 1113 and the second pressing area 1114 are located at the same side of the touch area 1111, and the first pressing area 1113 and the second area are respectively opposite to different positions where the elastic sheet 12 can move. Here, pressing the first pressing area 1113 corresponds to a function of pressing a left mouse button, and pressing the second pressing area 1114 corresponds to a function of pressing a right mouse button.

When the first pressing area 1113 and the second pressing area 1114 of the pressing area 1112 are pressed by mistake, the elastic piece 12 simultaneously abuts against the touch pad 11 corresponding to the first pressing area 1113 and the second pressing area 1114, so as to reduce the probability of inputting error information into the electronic device where the touch assembly is located due to the pressing area 1112 being pressed by mistake.

Here, the first and second pressing areas 1113 and 1114 may be located at the right side of the touch area 1111 as shown in fig. 4, or may be located at the side of the touch area 1111 close to the user as shown in fig. 5.

In some embodiments, the touch assembly may further include: and the detection pieces are respectively connected with the touch panel 11 and the electromagnetic structure 13, and can detect the contacted area of the first surface 111 of the touch panel 11 or the number of contact points of the first surface 111 of the touch panel 11.

When the contact area of the pressing area 1112 of the first surface 111 detected by the detecting element is greater than the preset area, the pressing area may be considered as a false pressing, and then the electromagnetic structure 13 may apply a driving force to the elastic sheet 12 to push the elastic sheet 12 to move toward the touch panel 11 and abut against the touch panel 11, so as to block the input of the false information under the condition of false pressing. Here, the preset area may be a maximum area contacted with the touch panel 11 of the electronic device when a single finger clicks the touch panel 11, such as: the pressing area 1112 is covered with both hands of the user, and at this time, the contacted area of the first surface 111 of the touch panel 11 is larger than the preset area.

When the number of contact points of the pressing area 1112 of the first surface 111 detected by the detecting element is greater than or equal to two, at this time, the false pressing can be considered, and then the electromagnetic structure 13 can apply a driving force to the elastic sheet 12 to push the elastic sheet 12 to move towards the direction of the touch panel 11 and abut against the touch panel 11, so as to block the input of the false information under the condition of the false pressing.
