DETAILED DESCRIPTION OF THE INVENTION
The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying drawings where the components are illustrated based on a proportion for explanation but not subject to the actual component proportion.
Referring to FIG. 1 to FIG. 4, the present invention provides a gun vibration structure 100 for somatosensory games; comprising a gun body 10, a trigger 20, a microswitch 30, a vibration unit 40, and a connector 50. In the embodiment of the present invention, the profile of the gun body 10 is in a form of handgun; in other embodiment, it can also be in a form of rifle.
The gun body 10 comprises a body portion 11 and a grip portion 12. The body portion 11 comprises a housing space 13 which is approximately formed in a long shape and comprises a fix seat 14. As shown by FIG. 2, the fix seat 14 comprises a first fix block 15 on the front side thereof, and a second fix block 16 on the rear side thereof. The first fix block 15 and the second fix block 16 are fixed to the body portion 11 or integrally formed with the body portion 11.
The trigger 20 is disposed on the front side of the grip portion 12. Therein, the trigger 20 is located in a trigger guard 17 for being pressed to operate by the user. A recover spring 21 is disposed behind the trigger 20 for recovering the position of the trigger 20.
The microswitch 30 is disposed on the grip portion 12 and actuated by the trigger 20 which is pressed.
The vibration unit 40 is disposed in the housing space 13. The vibration unit 40 comprises an electromagnet 41 and an actuation rod 42 passing through the electromagnet 41. In the embodiment of the present invention, the operation voltage of the electromagnet 41 is a 24V direct current. When the electromagnet 41 is electrified, the actuation rod 42 is allowed to reciprocate with respect to the electromagnet 41, so as to ram the body portion 11 to generate the vibration in the housing space 13. To further illustrate, the actuation rod 42 comprises a first end 421 and a second end 422, wherein the first end 421 faces the first fix block 15, and the second end 422 faces the second fix block 16. When the electromagnet 41 is electrified, the coil inside the electromagnet 41 generate a magnetic field effect, such that the actuationod 42 moves from a first position to a second position; when the electromagnet 41 is diselectrified, the actuation rod 42 recovers from the second position to the first position. The process of the actuation rod 42 moving from the first position to the second position and then moving from the second position back to the first position is defined as a travel. In this travel of the actuation rod 42, the first end 421 rams the first fix block 15, and the second end 422 subsequently rams the second fix block 16. Such ramming allows the gun body 10 to produce a realistic vibration effect, so that the user holding the gun body 10 feels an obvious and realistic vibration.
Also, the second end 422 of the actuation rod 42 comprises a stop 423, with a recover spring 60 disposed between the stop 423 and the electromagnet 41. Therefore, when the electromagnet 41 is diselectrified, the actuation rod 42 moves from the second position back to the first position by the recover spring 60, whereby the second end 422 rams the second fix block 16. Therein, the operation direction of the actuation rod 42 is in parallel to the trigger 20.
Further, the connector 50 is an 8 P metal male connector. The connector 50 is disposed at the distal end of the grip portion 12 and electrically connected with the microswitch and the electromagnet 41. Furthermore, the signal connector 50 is electrically connected with a control device 70 through a transmission cable 71. The control device 70 sends the power and signal to the connector 50, such that when the microswitch 30 is pressed, the electromagnet 41 is electrified to operated.
In the present invention, the top face 11 of the body portion 11 comprises a fix portion 18 formed in a consecutive concave and convex shape, facilitating the removable combination between the gun body 10 and the signal sensing device of the somatosensory games.
Referring to FIG. 2 to FIG. 4, the operation status of the present invention is illustrated. As shown by FIG. 2, when the present invention is not operated, the actuation rod 42 of the vibration unit 40 is at the first position, wherein the actuation rod 42 is under the elastic effect of the recover spring 60, and the first end 421 does not yet protrude with respect to the electromagnet 41.
As shown by FIG. 3, when the user presses the trigger 20, the trigger 20 actuates the microswitch 30, and the microswitch 30 sends the signal back to the control device 70; the control device 70 electrifies the electromagnet 41, and the actuation rod 42 is triggered to move from the first position to the second position, whereby the first end 421 rams the first fix block 15 of the gun body 10.
As shown by FIG. 4, when the electromagnet 41 is diselectrifeid, the actuation rod 42 moves from the second. position back to the first position, whereby the second end 422 rams the second fix block 16 of the gun body 10, so that the gun body 10 produces the vibration effect. Therefore, when the user, during the gaming process, repeatedly presses the trigger 20, the actuation rod 42 is repeatedly operated, so as to continuously and alternately rams the first fix block 15 and the second fix block 16, whereby the gun body 10 produces obvious vibration effects due to repeating ramming of the actuation rod 42, providing the user with realistic sensation for enjoying somatosensory games.
The present invention substitutes the vibration motor with the electromagnet 41 and the actuation rod 42, not only providing an obvious vibration effect, but also achieving advantages of longer service life and lower power consumption.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
