[0024] A Hall rocker device, please refer to Figures 1 to 5 , including a rocker seat 1, a rocker shaft 2, a rocker ball 3 sleeved on the surface of the rocker shaft 2, an upper limit block 4 and a lower limit block 5 arranged in the rocker seat 1 and sleeved with the top and bottom of the rocker ball 3 respectively, a magnet 6 fixedly arranged at the bottom of the rocker shaft 2, a main board 7 arranged at the bottom of the rocker seat 1 and cooperating with the magnet 6, a pin rod limit groove 9, a limit pin rod 8, and a magnet limit groove 10;
[0025] Among them, a Hall element is arranged on the main board 7 to cooperate with the moving magnet 6 to generate an induction signal, thereby realizing the function of the rocker; the rocker seat 1 includes an upper rocker seat and a lower rocker seat detachably connected to the upper rocker seat, and the upper limit block 4 is integrally formed and prefabricated in the upper rocker seat; the pin rod limit groove 9 is arranged on one side surface of the rocker ball 3, and one end of the limit pin rod 8 is fixed in the rocker seat 1 and the other end is movably inserted into the pin rod limit groove 9 to limit the horizontal rotation of the rocker ball 3; the insertion end of the limit pin rod 8 inserted into the pin rod limit groove 9 is cylindrical, and the cutting width of the pin rod limit groove 9 is greater than the diameter of the insertion end of the limit pin rod 8, so that the rocker shaft 2 and the rocker ball 3 can realize a universal rotation with limited angle; for example, usually, the swing amplitude of the rocker shaft 2 needs to reach plus or minus 30 degrees, and at this time, it can be realized by reasonably setting the cutting width of the pin rod limit groove 9 and the diameter of the insertion end of the limit pin rod 8; the magnet limit groove 10 is arranged on the side of the lower limit block 5 facing away from the rocker ball 3, and the magnet 6 is accommodated in the magnet limit groove 10, so that the moving direction of the magnet 6 is restricted by the magnet limit groove 10;
[0026] In the above structure, through the cooperation of the limit pin rod 8 and the pin rod limit groove 9, the rocker ball 3 cannot rotate horizontally around the axis of the rocker shaft 2, but can perform a universal rotation with limited angle, thus avoiding damage to the rocker device caused by improper operation of the user and reducing the difficulty of using the rocker. For example, when the rocker shaft 2 or the rocker ball 3 rotates horizontally, excessive mechanical wear will occur between the rocker ball and the upper limit block 4 and the lower limit block 5, the threaded connection structure of the rocker cap 11 in the rocker device is likely to fall off, and the rubber protective sleeve 16 will be distorted. However, the present utility model can preferably avoid the above adverse effects on the Hall rocker device caused by improper operation by restricting the horizontal rotation of the rocker ball 3; further, since a magnet limit groove 10 is provided on the side of the lower limit block 5 facing away from the rocker ball 3, the moving direction of the magnet 6 at the bottom of the rocker shaft 2 is restricted through the magnet limit groove 10, so as to facilitate the control of the swinging direction of the rocker shaft 2 and further reduce the control difficulty of the rocker; and the specific shape of the magnet limit groove 10 can be reasonably set according to the swinging direction required to be controlled by the rocker shaft 2.
[0027] Further, in a preferred embodiment, please refer to Figure 4 and Figure 5 wherein the magnet limit groove 10 is a linear or cross-shaped groove for restricting the magnet 6 to move linearly or crosswise only within the magnet limit groove 10.
[0028] Further, in a preferred embodiment, please refer to Figure 1 and Figure 2 wherein the pin rod limit groove 9 is located on the maximum circumference of the rocker ball 3, and the cutting direction thereof is parallel to the axis of the rocker shaft 2, and the limit pin rod 8 is located on the horizontal diameter of the rocker ball 3; based on this setting, through the cooperation of the limit pin rod 8 and the pin rod limit groove 9, not only can the horizontal rotation of the rocker ball 3 be avoided, but also the rocker shaft 2 can swing greatly in a cross shape along the length direction of the limit pin rod 8 and around the limit pin rod 8 to cooperate with the linear or cross-shaped limit of the magnet limit groove 10, thereby improving the control stability of the swinging direction of the rocker; preferably, the length direction of the limit pin rod 8 is the same as the direction of any one of the grooves in the magnet limit groove 10.
[0029] For the convenience of installing the limit pin rod 8, further, in a preferred embodiment, please refer to Figure 1 wherein one end of the limit pin rod 8 is fixedly clamped between the upper limit block 4 and the lower limit block 5, and the other end is movably inserted into the pin rod limit groove 9.
[0030] Further, in a preferred embodiment, please refer to Figure 1 and Figure 2, the utility model further includes a lower return sleeve 12, a return spring 13 and an upper return sleeve 14 which are sleeved on the outside of the rocker shaft 2 in sequence from bottom to top. The lower end of the return spring 13 is fixedly connected with the lower return sleeve 12, and the upper end is fixedly connected with the outer surface of the rocker shaft 2. Based on the above settings, when the operator controls the swing of the rocker shaft 2, the spring 7 is deformed by force. When the operator releases the rocker shaft 2, the rocker shaft 2 can be reset by the resilience of the spring 7, thus facilitating the use of the operator.
[0031] Further, in a preferred embodiment, please refer to Figure 1 and Figure 2 , the utility model further includes a rocker cap 11 threadedly connected to the top of the rocker shaft 2, and a rubber protective sleeve 16 sleeved on the outside of the rocker shaft 2 and connected to the rocker cap 11 at the upper end and fixedly connected to the rocker seat 1 at the lower end. Based on the above settings, the rocker cap 11 facilitates the hand control of the rocker shaft 2, and the rocker cap 11 and the rubber protective sleeve 16 are connected as a whole, which can protect the internal components of the Hall rocker device together without affecting the swing of the rocker shaft 2.
[0032] Further, in a preferred embodiment, please refer to Figure 1 and Figure 2 , a snap ring 17 is arranged at the top of the upper return sleeve 14, and the upper return sleeve 14 is connected to the inner wall of the top of the rubber protective sleeve 16 through the snap ring 17.
[0033] Further, in a preferred embodiment, please refer to Figure 1 and Figure 2 , the utility model further includes a rubber pressing plate 15 arranged at the top of the rocker seat 1, and the lower end of the rubber protective sleeve 16 is fixedly connected to the rocker seat 1 through the rubber pressing plate 15.
