The trigger assembly and the control device provided by the utility model are described in detail below with reference to the embodiments.

Referring to fig. 1, 2 and 3, fig. 1 is a schematic view of a first state structure of a first embodiment of a trigger assembly of the present application; FIG. 2 is a schematic cross-sectional view of a first state of a first embodiment of the trigger assembly of the present application; FIG. 3 is a schematic view of a second state construction of the first embodiment of the trigger assembly of the present application. The present application provides a trigger assembly 10. The trigger assembly 10 includes a trigger frame 1, a trigger housing 2, a switch assembly 4, and a hall assembly 5.

The short-range function may be a click trigger in a game, a single point rapid shooting, a rapid attack, etc. The switch assembly 4 is detachably connected to the trigger frame 1. When the trigger assembly 10 is required to use the short stroke function, the switch assembly 4 is positioned within the receiving slot 3 and mounted to the trigger frame 1. The switch assembly 4 can be removed from the receiving slot 3 when the trigger assembly 10 needs to be replaced with another function. I.e. the switch assembly 4 can be mounted and dismounted according to the actual requirements.

The hall element 5 is located outside the receiving slot 3. Meanwhile, the hall assembly 5 is disposed between the trigger housing 2 and the circuit control board 30. By locating the hall assembly 5 between the trigger housing 2 and the circuit control board 30 rather than within the receiving slot 3, a large amount of space is available within the receiving slot 3 for mounting the switch assembly 4. The hall assembly 5 enables the trigger assembly 10 to perform a long travel function. The long-stroke function can be to simulate the effect of throttle and the effect of stepping on the brake.

As shown in fig. 1 and 2, when the trigger assembly 10 needs to use the short stroke function, the trigger housing 2 is pressed due to the switch assembly 4 being installed in the receiving groove, and the trigger housing 2 acts on the switch assembly 4 to trigger the switch assembly 4, thereby realizing the short stroke function of the trigger assembly 10. At this time, the switch assembly 4 can limit further movement of the trigger housing 2 due to the switch assembly 4, and thus the hall assembly 5 cannot be triggered.

When the trigger assembly 10 needs to use the long stroke function, as shown in fig. 3, the switch assembly 4 is removed from the receiving groove 3, the trigger housing 2 is pressed, and the trigger housing 2 moves to trigger the hall assembly 5, thereby realizing the long stroke function of the trigger assembly 10.

The switch assembly 4 is located in the accommodating groove 3 formed by the trigger frame 1 and the trigger housing 2, and the hall assembly 5 is located outside the accommodating groove 3 and between the trigger housing 2 and the circuit control board 30, so that the trigger assembly 10 can be compatible with the installation of the switch assembly 4 and the hall assembly 5, and the trigger assembly 10 can be compatible with the short-stroke function and the long-stroke function. When the trigger assembly 10 needs to use the long-stroke function, the long-stroke function of the trigger assembly 10 can be realized after the switch assembly 4 is disassembled. When the trigger assembly 10 is required to use the short stroke function, the switch assembly 4 is mounted in the receiving groove 3.

Therefore, through the mode, the short-stroke function and the long-stroke function of the trigger assembly 10 are compatible, when the short-stroke function or the long-stroke function is needed to be used, the whole structure of the trigger assembly 10 does not need to be replaced, only the switch assembly 4 is needed to be installed or the switch assembly 4 is needed to be disassembled, the structure is simple, parts are reduced, and the cost is saved.

One of the micro switch 421, the tact switch 422, the carbon dot silica gel switch 423, the capacitance sensing switch and the pressure sensitive switch is mounted on the switch circuit board 41. It should be noted that the micro switch 421, the tact switch 422, the carbon point silica gel switch 423, the capacitance sensing switch and the pressure sensing switch are conventional switch components in the art, and the principle and the use process thereof are not described in detail herein. In actual process, at least two of the micro switch 421, the touch switch 422, the carbon-point silica gel switch 423, the capacitive sensing switch and the pressure-sensitive switch may be stacked, which may be determined according to the requirements of those skilled in the art, and is not limited herein.

In a specific embodiment, the end of the pressing portion 21 facing the switching member 42 may be provided with the buffer layer 23. The buffer layer 23 may be detached or fixed at an end of the pressing portion 21 facing the switching piece 42. Specifically, the buffer layer 23 is embedded in the end of the pressing portion 21. The buffer layer 23 can absorb the mounting error between the pressing portion 21 and the switch member 42, and can improve the hand feeling of the user. The buffer layer 23 may be a silica gel layer or the like.

In one embodiment, the hall assembly 5 includes a hall sensing element 51 and a magnetic element 52 that cooperates with the hall sensing element 51. The magnetic member 52 forms a certain magnetic property. The magnetic member 52 is provided outside the trigger housing 2. The magnetic member 52 may be removable or fixed to the outer side of the trigger housing 2. The hall sensing element 51 is provided in the circuit control board 30. The hall sensing element 51 is detachable or fixed to the circuit control board 30.

When the trigger frame 1 is pressed, the magnetic member 52 gradually approaches the hall sensing member 51, so that the hall sensing member 51 recognizes the position of the magnetic member 52 and outputs a linear value, and the linear value is transmitted to the circuit control board 30, so that the linear function of the trigger assembly 10 is realized, and the long-stroke function is further realized. The magnetic member 52 may be a magnet. The hall sensing element 51 is a hall sensor. The working principle between the hall sensor and the magnet is a conventional scheme of a person skilled in the art, and is not described in detail herein.

In one embodiment, the outer side of the trigger housing 2 is provided with a connecting slot 241. The magnetic member 52 is embedded in the connecting groove 241. The coupling groove 241 provides an installation space for the magnetic member 52. By directly embedding the magnetic member 52 in the connecting groove 241, not only the magnetic fixing structure member (not shown) can be reduced, but also the cost can be saved; but also reduces assembly costs. Wherein the outer side surface of the trigger housing 2 is convexly provided with a connecting part 24. The connecting portion 24 is provided with the connecting groove 241. The connecting part 24 is arranged on the outer side surface of the trigger shell 2 in a protruding way, so that the space in the accommodating groove 3 is further enlarged, and the switch assembly 4 is convenient to install.

In one embodiment, the trigger housing 2 rotates about one end of the trigger frame 1. When the trigger housing 2 is depressed, the trigger housing 2 can be rotated at an angle relative to the trigger frame 1 to enable the trigger housing 2 to act on the switch assembly 4 or trigger the hall assembly 5, etc.

Specifically, the trigger frame 1 is formed at one end thereof with two rotation shaft holes (not shown). The rotation shaft 61 sequentially penetrates through the rotation shaft hole, the trigger housing 2 and the other rotation shaft hole, so that one end of the trigger housing 2 can rotate around one end of the trigger frame 1. When the trigger housing 2 is pressed against the switch assembly 4, the trigger housing 2 rotates relative to the trigger frame 1, and the switch assembly 4 is then triggered by the pressing portion 21. Alternatively, when the switch assembly 4 is removed, the trigger housing 2 is rotated at an angle relative to the trigger frame 1, changing the distance between the magnetic member 52 on the trigger housing 2 and the hall sensing member 51 on the circuit control board 30, thereby triggering the hall assembly 5.

In addition, the rotating shaft 61 is sleeved with a torsion spring 62. One torsion leg of the torsion spring 62 is connected to the trigger frame 1 and the other torsion leg of the torsion spring 62 is connected to the trigger housing 2. By providing torsion spring 62, trigger housing 2 is defined on trigger frame 1, thereby defining the angle of rotation of trigger housing 2 relative to trigger frame 1, reducing the risk of trigger housing 2 being ejected from trigger frame 1.
