[0017] The present invention will be further described in conjunction with the following embodiments.
[0018] Depend on Figures 1 to 4 As can be seen, the ball-type bidirectional tilt switch described in this embodiment includes a base 1 and a top cover 2; a receiving cavity 6 is formed between the base 1 and the bottom cover; the base 1 is provided with a lower conductive element 3 in the receiving cavity 6; the top cover 2 is provided with a left conductive element 4 and a right conductive element 5 in the receiving cavity 6; The lower conductive element 3 is located at the bottom of the accommodating cavity 6; the left conductive element 4 and the right conductive element 5 are both located at the top of the accommodating cavity 6. The lower conductive member 3 has a first lower conductive portion 31 on one side of the accommodating cavity 6; the lower conductive member 3 has a second lower conductive portion 32 on the other side of the accommodating cavity 6; the left conductive member 4 has a left conductive portion 41 on one side of the accommodating cavity 6; the right conductive member 5 has a right conductive portion 51 on the other side of the accommodating cavity 6. A conductive bead 61 is movably disposed within the accommodating cavity 6.
[0019] Specifically, in this embodiment, when the ball-type bidirectional tilt switch is placed horizontally, the conductive ball 61 naturally rests on the flat part 33 of the lower conductive member 3 under the action of gravity, and the conductive ball 61 does not contact the left conductive part 41 and the right conductive part 51.
[0020] When the ball-type bidirectional tilt switch is tilted, the conductive ball 61 in the accommodating cavity 6 will roll with the change of posture; when tilted towards the side where the first lower conductive part 31 and the left conductive part 41 are located, the conductive ball 61 can simultaneously abut against the two, thereby making the lower conductive part 3 and the left conductive part 4 conduct; when tilted towards the side where the second lower conductive part 32 and the right conductive part 51 are located, the conductive ball 61 abuts against the component on that side, thereby making the lower conductive part 3 and the right conductive part 5 conduct; in this embodiment, the circuit switching between different conductive parts is realized through the bridging effect of the conductive ball 61.
[0021] This embodiment achieves bidirectional tilt triggering function through the layout of the lower conductive element 3, the left conductive element 4, and the right conductive element 5, breaking through the application limitations of traditional unidirectional tilt switches and adapting to scenarios requiring bidirectional attitude detection. The movable design of the conductive bead 61 eliminates the risk of mechanical wear. Compared with the fixed contact structure, it has a more sensitive conduction response and can reduce contact problems caused by contact oxidation.
[0022] This embodiment describes a ball-type bidirectional tilt switch, in which the base 1 and the lower conductive component 3 are integrally molded by embedded injection molding. The embedded injection molding process allows the lower conductive component 3 to be pre-placed in the mold cavity before injecting plastic material to form the base 1, making the lower conductive component 3 and the base 1 an inseparable whole. This avoids the traditional step of first injection molding the base 1 and then assembling the conductive component, eliminating assembly gaps from the source. Furthermore, the integral molding structure ensures the precise positioning of the lower conductive component 3 within the receiving cavity 6, eliminating the risk of displacement or loosening, and guaranteeing the stability of the contact between the conductive ball 61 and the first lower conductive part 31 and the second lower conductive part 32. Simultaneously, it eliminates subsequent assembly processes, improving production efficiency and reducing product defect rates caused by assembly errors.
[0023] This embodiment describes a ball-type bidirectional tilt switch, in which the left conductive component 4, the right conductive component 5, and the top cover 2 are integrally molded by embedded injection molding. The embedded injection molding process allows the left conductive component 4 and the right conductive component 5 to be pre-placed in the mold cavity before injecting plastic material to form the top cover 2. This makes the left conductive component 4, the right conductive component 5, and the top cover 2 an inseparable whole, avoiding the traditional steps of first injection molding the top cover 2 and then assembling the left conductive component 4 and the right conductive component 5, thus eliminating assembly gaps from the source. Furthermore, the integral molding structure ensures the precise positioning of the left conductive component 4 and the right conductive component 5 within the receiving cavity 6, eliminating the risk of displacement or loosening and ensuring the stability of the contact between the conductive ball 61 and the left conductive part 41 and the right conductive part 51. Simultaneously, it eliminates subsequent assembly processes, improving production efficiency and reducing the product defect rate caused by assembly errors.
[0024] This embodiment describes a ball-type bidirectional tilt switch, wherein the lower conductive member 3 includes a flat portion 33 disposed in the middle of the accommodating cavity 6; a first inclined portion 34 is provided between the first lower conductive portion 31 and the flat portion 33; and a second inclined portion 35 is provided between the second lower conductive portion 32 and the flat portion 33. Specifically, the flat design of the flat portion 33 ensures that the conductive ball 61 does not shift in a horizontal state, maintains a stable open circuit, and improves the attitude detection accuracy of the switch; the first inclined portion 34 and the second inclined portion 35 provide a guiding path for the rolling of the conductive ball 61. When the switch is tilted, the conductive ball 61 can smoothly slide along the first inclined portion 34 or the second inclined portion 35 to the corresponding first lower conductive portion 31 or second lower conductive portion 32, avoiding jamming in the transition area.
[0025] In this embodiment, a ball-type bidirectional tilt switch has a height greater than that of the first lower conductive part 31 and the second lower conductive part 32; the angle between the first lower conductive part 31 and the flat part 33 is greater than the angle between the second lower conductive part 32 and the flat part 33. Specifically, the difference in height and angle means that the tilt angle required for the conductive ball 61 to roll to the first lower conductive part 31 is greater, requiring overcoming a greater height difference and a steeper tilt surface. The tilt angle required to roll to the second lower conductive part 32 is smaller, achieving differentiated settings for bidirectional trigger angles, improving the switch's scene adaptability, and avoiding functional redundancy or misjudgment caused by consistent bidirectional trigger thresholds.
[0026] In this embodiment, a ball-type bidirectional tilt switch is described. When the conductive bead 61 moves to one side of the accommodating cavity 6, it abuts against the first lower conductive part 31 and the left conductive part 41 respectively. When the conductive bead 61 moves to the other side of the accommodating cavity 6, it abuts against the second lower conductive part 32 and the right conductive part 51 respectively. Specifically, the conductive bead 61 has conductive properties. When the conductive bead 61 abuts against the first lower conductive part 31 and the left conductive part 41 simultaneously, a conductive path can be formed between the lower conductive element 3, the conductive bead 61, and the left conductive element 4. When the conductive bead 61 abuts against the second lower conductive part 32 and the right conductive part 51 simultaneously, a conductive path can be formed between the lower conductive element 3, the conductive bead 61, and the right conductive element 5.
[0027] This embodiment describes a ball-type bidirectional tilt switch. The lower conductive element 3 has a lower pin 36, which protrudes from the base 1. The left conductive element 4 has a left pin 42, which protrudes from the top cover 2. The right conductive element 5 has a right pin 52, which protrudes from the top cover 2. Specifically, the protruding pins can be directly connected to an external circuit. The lower pin 36 serves as a common terminal, and the left pin 42 and right pin 52 serve as trigger signal terminals in two directions, respectively. The external circuit obtains the tilt attitude information of the switch by detecting the on / off state between the left pin 42 and the right pin 52 and the lower pin 36, respectively.
[0028] This embodiment describes a ball-type bidirectional tilt switch, in which the accommodating cavity 6 is provided with multiple conductive beads 61 along its length. This arrangement improves the switch's conductivity reliability and reduces product scrap rates caused by stuck conductive beads 61. Simultaneously, the synergistic effect of multiple conductive beads 61 increases the conductive contact area, reduces conduction resistance, decreases current transmission loss, and improves the circuit's trigger sensitivity.
[0029] This embodiment describes a ball-type bidirectional tilt switch, wherein the top cover 2 is provided with a connecting post 21; the base 1 is provided with a connecting groove 11 that mates with the connecting post 21. During assembly, the connecting post 21 of the top cover 2 is inserted into the connecting groove 11 of the base 1, and the two are precisely positioned and fixed through an interference fit or a snap-fit structure, ensuring that there is no relative displacement after the top cover 2 and the base 1 are engaged.
[0030] In this embodiment, a ball-type bidirectional tilt switch is provided, wherein the bottom of the top cover 2 is provided with a limiting protrusion 22, and the top of the base 1 is provided with a limiting groove 12 that cooperates with the limiting protrusion 22. The above configuration can ensure the stability of the connection between the top cover 2 and the base 1.
[0031] The ball-type bidirectional tilt switch described in this embodiment is simple to assemble and can be assembled using an SMT placement machine, thus accelerating production efficiency.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
