Detailed Description

The embodiment of the application discloses a touch device, which can obviously improve the use experience of a user in the aspect of pressing strength.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 8, an embodiment of the present application provides a touch device, which may be applied to an electronic device such as a notebook computer, a tablet computer, a mobile phone, an intelligent door lock, and an inquiry machine, where the electronic device has a requirement for input through a touch action and a press action, the touch device can convert the touch action and the press action into electrical signals, and has a press trigger 8, a first surface of the touch device is a press surface, and the press trigger 8 is disposed in a middle of a second surface of the touch device, where the first surface and the second surface are two opposite surfaces of the touch device. That is, the second surface of the touch member is the other surface opposite to the pressing surface, the middle of the second surface corresponds to the middle of the pressing surface, and the middle of the second surface is the geometric center area of the second surface, and the distances from the geometric center area to the edge of the pressing surface in two opposite directions along the same straight line are approximately equal. Because press trigger 8 and set up the middle part at the second face, when each region that utilizes the press surface was pressed, can obviously reduce the difference degree of the required strength of pressing of different regions like this, avoid appearing the required too big condition of strength of pressing relatively of a certain region to help promoting user's use and experience. That is to say, compare with traditional touch device, this application is through pressing trigger 8 setting up the position in the middle part that corresponds the press surface for press trigger 8 area around can both regard as the press area relatively evenly, and not design the press area in the place that is close to a certain side border of press surface alone (for example the border that the display screen was kept away from to the touch pad common in the notebook computer), like this, no matter the user carries out the action of pressing in which place of press surface, required pressure strength all is roughly equal, has avoided appearing the condition that certain regional required pressure strength is too big relatively, makes user's use experience promote.

Specifically, the touch device of the present application further includes: and the bearing part 1 is arranged on the same side of the touch component and the second surface and can bear the touch component, and a force application part 11 is arranged at the position, corresponding to the pressing trigger 8, of the bearing part 1. The touch assembly is supported by the carrier 1 through an elastic piece 7 arranged between the touch assembly and the carrier 1, the touch assembly is movably connected with the carrier 1 through a plurality of movement guide structures, the movement guide structures are distributed around the pressing trigger 8, and the movement guide structures allow the touch assembly to move towards the direction close to the carrier 1 along the bearing direction of the carrier 1 when the pressing surface is pressed, but limit the touch assembly to move towards the direction far away from the carrier 1 along the bearing direction of the carrier 1. The carrying direction of the carrier 1 is a direction perpendicular to the pressing surface of the touch member in the initial state. The bearing part 1 is located on one side, far away from the pressing surface, of the touch assembly, the elastic part 7 is connected with the touch assembly to realize bearing of the touch assembly, when a user presses the pressing surface, the touch assembly overcomes the elastic restoring force of the elastic part 7 to move towards the bearing part 1, the pressing trigger part 8 on the touch assembly corresponds to the force application part 11 of the bearing part 1, the pressing trigger part 8 abuts against the force application part 11 along with the movement of the touch assembly towards the bearing part 1, then the force application part 11 applies acting force to the pressing trigger part 8 to trigger an electric signal, and the pressing action of the user is converted into the electric signal. Since the pressing trigger 8 is disposed in the middle of the second surface of the touch assembly, after the pressing trigger 8 contacts the force application part 11, the touch assembly can be understood as a seesaw with the contact position of the trigger and the force application part 11 as a fulcrum, and as the current pressing area moves in the direction approaching the carrier 1, the other area on the other side of the fulcrum relative to the current pressing area tends to move in the direction away from the carrier 1, but since the movement guide structures are disposed at multiple positions distributed around the pressing trigger 8, the movement of the other area is limited by some movement guide structures, i.e., the other area cannot move in the direction away from the carrier 1 in the carrying direction of the carrier 1, so that another fulcrum is formed at some movement guide structures for limiting, and together with the aforementioned fulcrum (i.e., the contact position of the trigger and the force application part 11), the touch assembly can be understood as a lever A rod. As shown in fig. 5 and 6, assuming that the pressing force applied to the touch assembly is a force F1 and the force applied to the pressing trigger 8 by the force applying part 11 is a force F2, the force F1 and the force F2 form a lever balance with the movement guide structure at the section a-a as a fulcrum, so that F1 × arm L1 is F2 × arm L2, and due to the amplification of the lever (arm L2 is smaller than arm L1, so that the force F2 is larger than the force F1), the required pressing force does not become larger as the position of the point of action of the force F1 on the pressing surface is farther from the pressing trigger 8 as in the conventional touch device. As can be seen from fig. 5 and 6, when the position of the action point of the force F1 is closer to the pressing trigger 8, the whole touch assembly moves toward the direction close to the carrier 1 along the carrying direction of the carrier 1, i.e. the aforesaid seesaw and lever are not formed at this time, and when the position of the action point of the force F1 exceeds a certain range from the pressing trigger 8, a part of the touch assembly moves toward the direction close to the carrier 1 along the carrying direction of the carrier 1, and another part of the touch assembly tends to move away from the carrier 1 along the carrying direction of the carrier 1, thereby forming the aforesaid seesaw and lever.

In a preferred embodiment, the present application provides a structure of the urging portion 11 satisfying: when the elastic member 7 is in the initial state and the pressing surface is not pressed, the urging portion 11 is in contact with the pressing trigger 8 and does not generate a pressure. This can reduce the stroke of pressing to further promote user's use experience. Since the force application part 11 is already in contact with the pressing trigger 8 when the elastic member 7 is in the initial state, a stroke for eliminating a gap between the pressing trigger 8 and the force application part 11 is omitted, and a force which is originally required by a user to overcome the elastic restoring force of the elastic member 7 in the stroke is omitted. In order to realize the contact between the force application part 11 and the pressing trigger 8 in the initial state, the force application part 11 is in a boss shape. Of course, in other embodiments, a boss may be disposed in the middle of the second surface of the touch member, and the pressing trigger 8 may be disposed on the boss to contact the force application portion 11 of the carrier 1.
