Detailed Description
The following describes a preferred embodiment of the present invention in detail with reference to the accompanying drawings. It is to be understood that the invention is not limited to the particular embodiments described above, and that devices and structures not described in detail are understood to be implemented in a manner common in the art; without departing from the scope of the invention, it is intended that the present invention be limited to the accompanying claims and, together with the description, further serve to explain the principles of the invention.
As shown in fig. 1, the utility model discloses a translation motion switch that can automatic playback, including push rod 1, pendulum rod 2, mounting 3, casing 4, magnetic part and magnetic attraction part.
The push rod 1 is used for controlling the connection and disconnection of the switch; the push rod is provided with an inserting structure.
The swing rod 2 is inserted in the insertion structure and swings with the insertion structure as an axis.
The fixing member 3 is used for fixing the magnetic attraction part. The magnetic attraction part can be formed on the fixing piece in an injection molding mode or directly arranged on the fixing piece.
The magnetic part is arranged at the bottom of the swing rod.
The magnetic attraction part and the magnetic part are arranged in mutual central symmetry, and the magnetic attraction part is used for attracting the magnetic part so as to enable the swing rod to return to an initial position after swinging.
The push rod is installed on casing 4, and the mounting passes through the buckle joint on the casing, and the push rod slides relatively between casing and mounting.
In this embodiment, the magnetic member is a magnet 2.1, and the magnetic attraction member is a ferromagnetic metal sheet 3.1. The magnet 2.1 is injection molded as an insert or mounted on the rocker 2, and the metal sheet 3.1 is injection molded as an insert or mounted directly on the fixing part 3.
The magnet 2.1 is placed above the metal sheet 3.1, the swing rod 2 is in direct contact with the fixing piece 3, and the relative position is kept unchanged through the magnetic field force between the magnet 2.1 and the metal sheet 3.1. The push rod 1 is arranged on the shell 4 and is provided with a guide for the movement of X +, X-, Y + and Y-in four directions on the plane; mounting 3 passes through the buckle joint on casing 4, and the pendulum rod 2 inserts the downthehole that push rod 1 corresponds, and push rod 1 is the relative slip between casing 4 and mounting 3.
When force in the X + direction is applied to the push rod 1, the push rod 1 drives the swing rod 2 to swing, the magnet 2.1 swings by taking the contact rib in the X + direction at the bottom of the swing rod 2 as an axis, the magnet is far away from the metal sheet 3.1, the instantaneous force value of the swing starting to leave the surface of the metal sheet 3.1 is rapidly increased, the magnet rotates at a small angle along with the continuation of the movement, the magnetic field distribution changes, but the component in the horizontal direction balanced with the thrust needs to be multiplied by an angle coefficient, the change in the magnetic field force swinging process in the horizontal direction is small, and the force value is relatively stable.
The push rod 1 and the shell 4 are provided with an elastic stop position and a mechanical stop position to control the limit position of movement. When the push rod 1 moves to the deformable elastic stop position, the force value is increased, and the force value rises rapidly after the mechanical stop position is reached. When the force applied on the push rod 1 is released, the swing rod 2 drives the push rod 1 to automatically return to the initial position along with the magnet 2.1 due to the attraction between the magnet 2.1 and the metal sheet 3.1.
The other three directions are the same, the two swing rods 2 and the metal sheets 3.1 are arranged in mutual central symmetry, and when the two pairs of magnets 2.1 and the metal sheets 3.1 move in a certain direction, the two pairs of magnets and the metal sheets are simultaneously acted, so that the stress balance is kept.
The utility model designs the relative rotation of the magnet on the plane by utilizing the magnetic field force between the magnet and the metal sheet, and achieves a relatively constant hand feeling value by utilizing the component force of the rotation angle in the moving direction; the movement in any direction can be realized by adjusting the matching relationship between the magnet and the metal piece, and the structure is simple; the size of the operating force can be adjusted by adjusting the magnetic field intensity of the magnet, the change of parts is not involved, and the cost is saved; the component is automatically returned to the initial position by the force of the magnetic field naturally existing between the magnet and the metal sheet.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
