[ detailed description ] embodiments
The present invention will be further described with reference to the accompanying drawings and embodiments.
An embodiment of the present invention provides a touch feedback device for an electronic device, which can be a keyboard, a mobile phone or a computer, and can receive touch input from a user and provide force feedback.
As shown in fig. 1 to 3, the touch feedback device includes a touch panel 10, a mounting base 20, a first magnet 40 and a second magnet 60 a. The touch panel 10 is supported on the mounting base 20, and a receiving space 22 is formed between the touch panel 10 and the mounting base 20. The first magnet 40 and the second magnet 60a are both accommodated in the accommodating space 22, the first magnet 40 is fixed on the mounting base 20, the second magnet 60a is fixed on the touch panel 10, and orthographic projections of the first magnet 40 and the second magnet 60a on the touch panel 10 are not overlapped and are arranged at intervals. At least one of the first and second magnets 40 and 60a includes a coil assembly, and a winding plane of the coil assembly is perpendicular to the touch panel 10.
When a user touches the touch panel 10, the coil assembly is energized and generates a magnetic field. Because the winding plane of the coil assembly is perpendicular to the touch panel 10, and the orthographic projections of the first magnet 40 and the second magnet 60a on the touch panel 10 are not overlapped and are arranged at intervals, under the action of the magnetic field force, an acting force in a direction parallel to the surface of the touch panel 10 is generated between the first magnet 40 and the second magnet 60 a. Meanwhile, the first magnet 40 is fixed on the mounting base 20, the second magnet 60a is fixed on the touch panel 10, and the acting force between the first magnet 40 and the second magnet 60a can drive the touch panel 10 to move relative to the mounting base 20 along the direction parallel to the surface of the touch panel 10, so as to generate force feedback of transverse movement, thereby improving the experience of a user using the electronic equipment with the touch feedback device, and the force feedback of transverse movement does not cause a squeezing sense to the fingertips of the user.
In the present embodiment, only the first magnet 40 includes a coil assembly, and the second magnet 60a includes a magnet. The position of the coil assembly is kept unchanged all the time, so that the electric connection structure of the coil assembly is prevented from being influenced when the coil assembly moves, and the working stability of the touch control feedback device is improved. Also, only the first magnet 40 includes the coil assembly, which can simplify the circuit structure. In other embodiments, the first magnet 40 and the second magnet 60a may both include coil assemblies, or only the second magnet 60a may include coil assemblies and the first magnet 40 may include magnets.
Further, the coil assembly includes a coil 42 and a core 44, and the coil 42 is wound around the core 44. After the coil 42 is electrified to generate a magnetic field, the iron core 44 inside the coil 42 is magnetized, and the magnetic field generated by the magnetized iron core 44 is superposed with the magnetic field of the coil 42 to enhance the magnetism of the first magnet 40, so that the acting force between the first magnet 40 and the second magnet 60a is enhanced, and force feedback meeting the strength requirement is formed.
In order to make the coil 42 conductive when the touch panel 10 receives a touch input, the coil 42 and the touch panel 10 may be directly electrically connected, for example, by using a touch IC, or indirectly electrically connected, for example, by using a microprocessor.
In the present embodiment, the magnets of the second magnet 60a are made of a magnetic substance having a strong magnetic conductivity to be quickly magnetized by the magnetic field of the first magnet 40 when the coil 42 is energized, thereby increasing the feedback speed. Also, it is preferable to use a material such as soft iron or silicon steel, which is demagnetized more quickly, to cut off the force with the first magnet 40 in time when the coil 42 is deenergized, so that the feedback force is more harmonized with the touch input.
Referring mainly to fig. 3, the orthographic projection of the first magnet 40 on the second magnet 60a along the direction perpendicular to the winding plane falls on the second magnet 60a, i.e. the projection of the first magnet 40 coincides with the projection of the second magnet 60a along the direction perpendicular to the winding plane, and the force between the coinciding portions is parallel to the touch panel 10, so that the touch panel 10 moves along the direction parallel to the surface thereof as much as possible, further enhancing the tactile sensation of the user.
Referring mainly to fig. 3, the touch feedback device further includes an elastic member 70 connected between the mounting base 20 and the touch panel 10, and the mounting base 20 supports the touch panel 10 through the elastic member 70. In this embodiment, the elastic member 70 is a glue layer, and the touch panel 10 is adhered to the mounting base 20, and the glue layer can not only support the touch panel 10, but also position the touch panel 10. When the touch panel 10 moves in a direction parallel to the surface of the touch panel 10, the adhesive layer is slightly deformed. In other embodiments, the resilient member 70 may be a spring.
The mounting base 20 includes a base opposite to the touch panel 10 and disposed at an interval, and an extending portion bent and extending from an edge of the base toward the touch panel 10, and the elastic member 70 is sandwiched and connected between the extending portion and the touch panel 10. Specifically, in the present embodiment, the elastic member 70 is located between the side wall of the accommodating space 22 and the side wall of the touch panel 10, and when the touch panel 10 moves along the direction parallel to the surface thereof, the elastic member 70 is compressed. The elastic member 70 is preferably a glue layer disposed around the touch panel 10, and the glue layer can also perform a sealing function to prevent dust or moisture from entering the accommodating space 22. In other embodiments, the elastic member 70 may be located on the upper surface of the extending portion, and the touch panel 10 is supported above the elastic member 70.
Moreover, in the present embodiment, the touch panel 10 is located on the step surface, and the surface of the touch panel 10 is coplanar with the surface of the mounting base 20, so as to improve the surface flatness of the touch feedback device.
In addition, the touch feedback device further includes a reset element 80 for driving the touch panel 10 to reset when the coil 42 is powered off. The restoring member 80 may be a spring structure, or a column structure made of an elastic material such as rubber.
Specifically, the reset member 80 is elastically supported between the second magnet 60a and the mounting base 20, one end of the reset member 80 is connected to the second magnet 60a, the other end of the reset member is connected to the mounting base 20, and the reset member 80 is always connected to the second magnet 60a and the mounting base 20, so that the touch panel 10 is more stable when moving. When the touch panel 10 moves in a direction parallel to the surface thereof, the reset member 80 is deformed by a force and stores elastic potential energy. After the coil 42 is powered off, the reset member 80 releases the elastic potential energy to drive the touch panel 10 to reset. In other embodiments, the reset element 80 may be spaced apart from the second magnet 60a or the mounting base 20, and only contact with the second magnet 60a and the mounting base 20 after the touch panel 10 moves a certain distance to approach the mounting base 20.
It should be noted that in the present embodiment, the force between the first magnet 40 and the second magnet 60a only drives the touch panel 10 to move in one direction, and drives the touch panel 10 to reset through the reset element 80, the reset element 80 can respond in time after the coil 42 is powered off, and the coil 42 only passes through the current in the same direction, which can simplify the control procedure and the circuit structure. In other embodiments, the touch panel 10 can be reset by changing the power direction of the coil 42. For example, if the coil 42 is energized to generate a force for driving the touch panel 10 to move in a direction parallel to the surface when the touch panel 10 receives a touch input, after the force feedback is completed, the coil 42 is energized with a current in an opposite direction, and at this time, the magnetic field direction of the first magnet 40 is changed, so as to drive the touch panel 10 to reset in the opposite direction.
It should be noted that the above description only takes one first magnet 40 and one second magnet 60a as an example, but the touch feedback device is not limited to include only one first magnet 40 and one second magnet 60a, the first magnet and the second magnet may be provided in plural, each first magnet corresponds to each second magnet, and each set of the first magnet and the second magnet corresponds to a touch position on the touch panel 10, so that the user can obtain force feedback when touching different positions of the touch panel 10. The touch panel 10 is made of a flexible material to generate a local displacement to form a force feedback.
Further, in order to make the position of the force feedback more accurate, the distance of the coil 42 from the second magnet 60a corresponding to the coil 42 is minimized, and as shown in fig. 3, the distance of the coil 42 from the second magnet 60a corresponding to the coil 42 is smaller than the distance of the coil 42 from the second magnet 60b to reduce the influence of the magnetic field of the coil 42 on the second magnet 60b when the coil 42 is energized.
The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.
