DETAILED DESCRIPTION

[0024] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined application purposes, the specific embodiments, structures, features and effects according to the present application will be described in detail below with reference to the drawings and preferred embodiments.

[0025] Referring to the drawings Figure 1 , Figure 2 and Figure 3 , the present embodiment discloses a multi-angle inclined ball switch, which comprises a base plate 1, a conductive shell 3 electrically connected to the base plate 1 and surrounding the base plate 1 to form a rolling cavity 2, a first electrode 4 arranged in the rolling cavity 2 and spaced apart from the conductive shell 3, and a conductive ball 5 arranged in the rolling cavity 2 and capable of connecting the conductive shell 3 and the first electrode 4. In use, the conductive shell 3 is electrically connected to the circuit board as one electrode, the first electrode 4 is electrically connected to the circuit board as another electrode, and the base plate is inclined so that the conductive ball 5 in the rolling cavity 2 rolls to a position where it is in contact with the conductive shell 3 and the first electrode 4 respectively, thereby realizing the conductive communication between the conductive shell 3 and the first electrode 4, and realizing the signal transmission of the ball switch. In the present embodiment, the conductive shell 3 comprises a top plate 3-1 arranged at the center and a contact part 3-2 arranged around the top plate 3-1 and bent towards the base plate 1 and connected to the base plate 1. When the base plate 1 is inclined, the conductive ball 5 rolls to the side of the rolling cavity 2 and is in contact with the contact part 3-2 and the first electrode 4 respectively. Further, as shown inFigure 6 As shown, the first electrode 4 in the embodiment includes several detection electrodes 4-1 arranged in a circle and spaced apart from each other,

[0026] The detection electrodes 4-1 are arranged in four directions respectively, and in the embodiment, four detection electrodes 4-1 are arranged in a circle and spaced apart in the rolling cavity 2. When the substrate 1 is tilted, as shown, Figure 4 the conductive ball 5 rolls to the low position, and at the same time, the conductive ball 5 contacts the contact part 3-2, thereby realizing the circuit communication of the ball switch. Further, in the embodiment, different detection electrodes 4-1 are connected to the circuit board through different signal lines, and when the conductive ball 5 rolls to the upper left detection electrode 4-1 and contacts the contact part 3-2, the signal is received in the line connected to the upper left detection electrode 4-1 on the circuit board, thereby reflecting that the ball switch is tilted to the upper left. Similarly, the direction in which the substrate is tilted is the direction of the line corresponding to the received signal.

[0027] Further, as shown in Figure 6 , Figure 7 and Figure 8 , the detection electrodes 4-1 in the embodiment are electrically connected to the limiting protrusions 6 corresponding to the detection electrodes 4-1 and protruding upward from the substrate 1. In the embodiment, the limiting protrusions 6 corresponding to the detection electrodes 4-1 are also provided with four limiting protrusions 6.

The several limiting protrusions 6 are arranged spaced apart from each other, the diameter of the conductive ball 5 is greater than the spacing between the limiting protrusions 6, and the several limiting protrusions 6 surround the conductive ball 5 once to limit the conductive ball 5 in the limiting protrusions 6 when in a horizontal state, so that the ball switch is in a closed state. At the same time, the limiting protrusions 6 are also arranged spaced apart from the conductive shell 3. The inner end of the limiting protrusion 6 is electrically connected to the detection electrode 4-1, and the upper end of the limiting protrusion 6 gradually extends upward from the inside to the outside, so that the upper end of the limiting protrusion 6 is electrically connected to the detection electrode 4-1 and gradually rises outward from the side of the detection electrode 4-1 to form a slope, thereby limiting the conductive ball 5 on the slope of the limiting protrusion 6 when the tilt angle of the substrate 1 is small, as shown, Figure 7 the conductive ball 5 is limited by the limiting protrusion 6, and at this time, the conductive ball 5 does not contact the conductive shell 3, and the ball switch in the embodiment does not transmit signals. Correspondingly, as shown in Figure 8As shown, when the substrate 1 is inclined at a large angle, the conductive ball 5 further rolls along the slope of the limiting protrusion 6 until it is limited by the outer conductive shell 3, at which time the conductive ball 5 is in conductive communication with the conductive shell 3, the limiting protrusion 6 and the detection electrode 4-1 in the corresponding direction, thereby realizing signal transmission of the ball switch; in the embodiment, the limiting protrusions 6 of different heights can be provided to change the inclination conduction angle of the corresponding ball switch (i.e. change the sensitivity of the ball switch) to meet different use requirements.

[0028] Further, as shown in Figure 3 and Figure 6 In order to facilitate the installation of the conductive shell 3, the upper end of the substrate 1 in the embodiment is provided with a conductive connecting portion 7 for connecting with the conductive shell 3, during installation, the conductive ball 5 is first placed in the rolling cavity 2 and then the conductive shell 3 is soldered on the upper end of the conductive connecting portion 7 by soldering, and then; wherein, as shown in Figure 5 The lower end of the substrate 1 in the embodiment is provided with external connecting electrodes 8 arranged transversely and electrically connected to the left and right sides of the conductive connecting portion 7, and then the conductive shell 3 realizes circuit connection with the external circuit board through the conductive connecting portion 7 and the external connecting electrodes 8 in turn; correspondingly, a plurality of internal connecting electrodes 9 are arranged at the lower end of the substrate 1 and electrically connected to the detection electrodes 4-1, thereby enabling the detection electrodes 4-1 to be connected to the external circuit board through the internal connecting electrodes 9.
