This non-provisional patent application claims priority under 35 U.S.C. § 119 from Chinese Patent Application No.CN202220792740.3 filed on Apr. 7, 2022, the entire content of which is incorporated herein by reference.
The disclosure relates to sensor technology, in particular to a joystick sensor and joystick controller.
The joystick sensor is one of the sensors and is often used as a VR joystick. The joystick sensor is mainly includes a rocker, two swing arms, a brush and a resistor piece. The rocker is toggled to drive the swing arm to operate, so that the brush moves on the carbon film to generate different resistance values, then generates different electrical signals which can use to control direction.
However, adjusting through the contact between the brush and the carbon film generally has the following defects: if a metal with greater elasticity is used as the brush, the brush wears quickly and the service life is short; if the metal with less elasticity is used as the brush When brushing, the contact between the brush and the carbon film is prone to poor contact and failure. If a high-hardness carbon film is used, the brushes will wear out quickly, which will generate large electrical noise; if a low-hardness carbon film is used, the surface of the carbon film will soon be ground toner by the brush, and the toner will also stick to the brush, affecting the electrical performance of the brush, causing the rocker device to malfunction.
Therefore, such joystick sensors generally have the defects of short service life and poor performance, which eventually lead to the “drift” problem of gamers during the game.
To solve the above problem, according to various embodiments of the present application, joystick sensor is provided.
A joystick sensor is provided, and includes a housing, a reset assembly, a rocker assembly, a circuit assembly, the reset assembly, the rocker assembly and the circuit assembly mounted on the housing; the rocker assembly comprising two magnets, an upper rocker arm, a lower rocker arm, and a rocker body, one end of the upper rocker connected with one of the two magnets; one end of the rocker arm connected with the other one of the two magnets, the other end of the lower rocker arm secured a pressing block; the circuit assembly comprising a flexible circuit board, two Hall IC elements, and a switch spring, the two Hall IC elements and the switch spring arrange on the flexible circuit board, positions of the two Hall IC elements respective corresponding to positions of the two magnet; a position of the switch spring corresponding to a position of the pressing block.
In the above joystick sensor, the combination of the magnet and the Hall IC element is arranged to obtain the swing of the rocker assembly in two directions, and the corresponding electrical signal output is converted and output. This method has the advantage of stable output signal, and then the accuracy of the rocker is improved; and there is no contact between the magnet and the Hall IC element, thereby avoiding friction and improving the service life.
The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms “center”, “upper”, “lower”, “left”, “right”, “vertical”, “horizontal”, “inner”, “outer”, etc. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the pointed device or element must have a specific orientation or a specific orientation. The structure and operation cannot therefore be understood as a limitation of the present invention. In addition, the terms “first”, “second”, and “third” are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms “installation”, “connection” and “connection” should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, connected or integrally connected; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication between two assemblies. For those of ordinary skill in the art, the specific meaning of the above-mentioned terms in the present invention can be understood in specific situations.
The technical solutions of the disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are a part of embodiments of disclosure , but not all of the embodiments of the disclosure.
Referring to
By integrating the Hall IC element 42 into the flexible circuit board 41, the flexible circuit board 41 is a magnetic induction IC board. The swing of the magnet 25 changes the distance between the magnet 25 and the Hall IC element 42. At this time, the magnetic induction IC board generates and outputs a corresponding electrical signal, so that the flexible circuit board 41 senses the moving direction of the rocker assembly 20, it is more accurate and the induction efficiency is improved.
Referring to
The number of the side edges 104 is 2-4, and there is a gap between the side edges 104 to enable the flexible circuit board 41 to extend out of the the housing 10. In this embodiment, the two side edges 104 are symmetrically arranged, and both ends of the two side edges 104 are bent inward by 90 degrees to form a buckle edge 105, which is fastened to the casing 11.
The upper rocker arm 22 and the lower rocker arm 23 are orthogonally arranged in the shell 11 to each other, and the rocker body 21 are passed through the upper rocker arm 22 and the lower rocker arm 23. In detail, as shown in
One end of the upper rocker arm 22 is provided with a magnet mounting position 205a, and one end of the lower rocker arm 23 is provided with a magnet mounting position 205b. The magnet mounting positions 205a and 205b are respectively disposed under the rotating shafts 201a and 201b. The magnet mounting positions 205a and 205b are provided with clamping part, and the magnet 25 is clamped and mounted on the magnet mounting positions 205a and 205b via the clamping part.
The pressing block 26 is installed below the rotating shaft 201b at the other end of the lower rocker arm 23, and the pressing block 26 is placed above the switch spring 43. The switch spring 43 is fixed on the flexible circuit board 41 by a film. The flexible circuit board 41 is provided with electrical contacts under the switch spring 43. The rocker body 21 drives the lower rocker arm 23 to press down on the pressing block 26, and the switch spring 43 is connected to the electrical contacts.which triggers the joystick sensor to turn on or off
As shown in
The rocker body 21 is movably connected to the rocker base 24 under the action of the spring, it prevents the rocker body 21 from being separated from the rocker base 24 during reset due to the reset assembly 30. The rocker base 24 is provided with a plurality of limit blocks 207 arranged along a circumference. The rocker body 21 defines corresponding limit slots 208 on an inner wall surrounding the receiving cavity 206, and the limit blocks 207 are inserted into the limit slots 208 to ensure the rocker body 21 fixed with the rocker base 24 in axial direction to prevent the rocker body 21 from rotating.
The above embodiments are only to describe the preferred embodiments of the joystick sensor, and do not limit the scope of the joystick sensor. On the premise of not departing from the design spirit of the joystick sensor, various modifications and changes made by ordinary engineers and technicians in the art to the technical solutions of the joystick sensor and improvements should all fall within the protection scope determined by the claims of the joystick sensor.
