Description

Technical Field

[0001] This application belongs to the field of encoder technology, and more specifically, relates to an encoder switch. Background Technology

[0002] In the field of encoder switch technology, different encoded signal outputs are typically achieved by rotating the shaft and changing the contact between the bottom of the shaft and different contact pieces. However, existing encoder switches have limited preset options for the contact between the bottom of the shaft and the contact pieces, resulting in a limited number of encoded signals that cannot meet the requirements. Utility Model Content

[0003] The purpose of this application is to provide an encoder switch to solve the technical problem of insufficient output signal of encoder switches in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application embodiment is to provide an encoder switch, which includes, from bottom to top, the following components in its height direction:

[0005] A base body, in which a receiving cavity is formed, and a plurality of connecting pieces are provided at the bottom of the receiving cavity. Pins that connect to each of the connecting pieces are also provided at the bottom or side of the base body.

[0006] A contact piece is mounted in the receiving cavity. The contact piece is provided with a number of spring arms that are the same as the number of connecting pieces. Each spring arm is directly opposite to each connecting piece in the height direction. Each spring arm includes a first spring arm and a plurality of second spring arms. The first spring arm is configured to always be in contact with the directly opposite connecting piece. Each second spring arm is spaced apart from each connecting piece in its natural state.

[0007] A rotating seat is rotatably disposed in the receiving cavity. Several protrusions are provided at the same or different radial positions and different circumferential positions on the bottom of the rotating seat. When the rotating seat rotates, the same or different protrusions can push different second elastic arms to bend and deform toward the bottom of the receiving cavity to contact the connecting piece.

[0008] Optionally, the connecting piece includes a first connecting piece and a plurality of second connecting pieces, each of the second connecting pieces being disposed around the first connecting piece.

[0009] Optionally, each of the second spring arms has a protrusion at the middle of the center that faces the bottom of the rotating base, and each of the second spring arms has an abutment portion that bends toward the connecting piece at its free end.

[0010] Optionally, each of the spring arms is integrally stamped onto the contact piece.

[0011] Optionally, a gasket is further provided between the contact piece and the rotating base, and a protrusion facing the rotating base is provided at the center of the gasket, the protrusion being higher than the protrusion and in contact with the bottom of the rotating base.

[0012] Optionally, an opening is provided on the gasket opposite each of the protrusions, the opening being for the protrusion to pass through.

[0013] Optionally, the protrusions are provided at the same or different circumferential positions on at least two circular tracks of different diameters at the bottom of the rotary seat; some of the protrusions have an arc length.

[0014] Optionally, some of the protrusions located in the same circumferential position and adjacent radial positions are connected together.

[0015] Optionally, a plurality of teeth are arranged in a circumferential array on the top of the rotary base, and a cover is also provided on the top of the base body. A third spring arm in an annular shape is provided on the cover, and the third spring arm is arranged directly opposite the annular teeth on the top of the rotary base. A positioning part that can be inserted into the teeth is provided on the third spring arm.

[0016] Optionally, the length directions of each of the second spring arms are parallel, the free ends of two adjacent second spring arms extend in opposite directions, and the protrusions on each of the second spring arms are arranged in the same radial direction.

[0017] The encoder switch provided in this application embodiment has at least the following beneficial effects:

[0018] By setting a first spring arm and several second spring arms on the contact piece, the first spring arm is always in contact with the connecting piece. At the same time, protrusions are set at the same or different radial and circumferential positions on the bottom of the rotating base. Different protrusions are used to push the same or different second spring arms into contact with the connecting piece. In this way, when one or more protrusions at the same radial position are in contact with different second spring arms respectively, multiple different second spring arms can simultaneously contact multiple connecting pieces, thereby realizing multiple different encoded switch signal outputs.

[0029] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0030] Please refer to the following: Figures 1 to 6 The encoder switch provided in the embodiments of this application will now be described.

[0031] Understandably, reference Figures 1 to 4 The encoder switch provided in this application embodiment includes, from bottom to top, a base 100, a contact piece 300, and a rotating base 400 in its height direction.

[0032] Specifically, a receiving cavity 110 is formed in the base 100, a plurality of connecting pieces 200 are provided at the bottom of the receiving cavity 110, and pins connected to each connecting piece 200 are also provided at the bottom or side of the base 100.

[0033] Understandably, reference Figure 2 The aforementioned connecting piece 200 includes a first connecting piece 210 and a second connecting piece 220. Each connecting piece 200 is electrically connected to the encoder controller. Meanwhile, each second connecting piece 220 is arranged around the first connecting piece 210. For example, in some embodiments, the first connecting piece 210 is located at the center of the bottom of the receiving cavity 110, and each second connecting piece 220 is arranged circumferentially around the first connecting piece 210. Each connecting piece 200 can be rectangular, and each second connecting piece 220 can be arranged in a rectangular pattern around the first connecting piece 210.

[0034] It is understood that the first connecting piece 210 and each of the second connecting pieces 220 are respectively connected to the encoder controller by electrical signals. When the first connecting piece 210 is connected to at least one of the second connecting pieces 220, the encoder controller can output an encoding signal.

[0035] refer to Figures 2 to 4 The contact piece 300 is mounted in the receiving cavity 110 and located directly above each connecting piece 200. The contact piece 300 is electrically connected to the encoder controller. The contact piece 300 has a number of spring arms that match the number of connecting pieces 200, and each spring arm is directly opposite to each connecting piece 200 in the height direction. Specifically, the spring arms include a first spring arm 310 and several second spring arms 320. The first spring arm 310 is configured to always be in contact with the directly opposite first connecting piece 210, while each second spring arm 320 has elastic deformation capability. In its natural state, each second spring arm 320 has a gap with each second connecting piece 220. In the deformed state, each second spring arm 320 can contact each second connecting piece 220 individually. It should be understood that one or more second spring arms 320 can simultaneously contact each second connecting piece 220, thereby combining to form multiple different switching signals.

[0036] refer to Figures 2 to 6 The rotary base 400 is rotatably mounted in the receiving cavity 110. Several protrusions 410 are arranged at the same or different radial and circumferential positions on the bottom of the rotary base 400. When the rotary base 400 rotates, the same or different protrusions 410 can push different second spring arms 320 to bend and deform towards the bottom of the receiving cavity 110 to contact the second connecting piece 220. Thus, when one or more protrusions 410 contact one or more second spring arms 320 respectively, different second spring arms 320 can simultaneously contact different second connecting pieces 220, thereby enabling the encoder controller to output different switching signals, increasing the number of encoder switching signal outputs.

[0037] Further reference Figures 2 to 6 In some embodiments, each second spring arm 320 has a protrusion 321 at its center facing the bottom of the rotary seat 400, and a contact portion 322 bending towards the connecting piece 200 at its free end. By providing the protrusion 321, the protrusion 410 at the bottom of the rotary seat 400 can better contact each second spring arm 320. This also improves the downward pressure effect of each second spring arm 320 and avoids the risk of the second spring arm 320 being accidentally pressed after the protrusion 410 leaves it, thus helping to ensure the stability and accuracy of different switch signal outputs. Furthermore, the free ends of both the first spring arm 310 and each second spring arm 320 are provided with contact portions 322 bending towards the connecting piece 200. Similarly, this helps to ensure the stability of the contact between the first spring arm 310 and the second spring arm 320 and the connecting piece 200, thereby ensuring the stability of the switch signal output.

[0038] refer to Figures 2 to 6 Furthermore, the first spring arm 310 and each of the second spring arms 320 on the contact piece 300 are formed by stamping.

[0039] Furthermore, the length directions of each second spring arm 320 are parallel, and the free ends of adjacent second spring arms 320 extend in opposite directions. Thus, the connection points between each second spring arm 320 and the contact piece 300 are located on both radial sides of the circular trajectory of the rotating base 400, and the structural strength of the contact piece 300 can effectively support each second spring arm 320.

[0040] In addition, refer to Figure 5 and Figure 6 The protrusions 321 on each of the second spring arms 320 are arranged at different radial positions in the same radial direction. Thus, corresponding to the design of each of the aforementioned second connecting pieces 220, each second protrusion 321 can be located above the gap between two adjacent second connecting pieces 220. This can prevent the second spring arm 320 from accidentally touching the second connecting piece 220 when the bottom protrusion 410 of the rotating seat 400 squeezes the protrusions 321 of the second spring arm 320.

[0041] refer to Figures 2 to 4 In some embodiments, a gasket 500 is further provided between the contact piece 300 and the rotating base 400. A protrusion 510 facing the rotating base 400 is provided at the center of the gasket 500. The protrusion 510 is higher than the protrusion 321 and contacts the bottom of the rotating base 400. By providing the gasket 500 and the protrusion 510 on the gasket 500, the protrusion 510 can support the rotating base 400, thereby avoiding the risk of accidental contact caused by the bottom of the rotating base 400 being too close to the protrusion 321 on each of the second spring arms 320.

[0042] Furthermore, an opening 520 is provided on the gasket 500 directly opposite each protrusion 321, allowing the protrusion 321 to pass through. It should be understood that the width of the opening 520 is slightly larger than the width of the second spring arm 320, and the length of the opening 520 is slightly larger than the length of the protrusion 321. In this way, the opening 520 can limit the protrusion 321, so as to prevent the second spring arm 320 from deforming when the bottom protrusions 410 of the rotary seat 400 rotate in the circumferential direction and collide with the protrusions 321.

[0043] refer to Figures 2 to 6 In some embodiments, four second spring arms 320 are provided, and two are provided on each side of the rotation center of the rotary seat 400. The radial distance from the protrusion 321 on each second spring arm 320 to the center of the contact piece 300 is not equal. Corresponding to the arrangement of the second spring arms 320, the protrusions 410 are provided at the same or different circumferential positions on at least two circular tracks of different diameters at the bottom of the rotary seat 400.

[0044] For example, when the distance from the protrusion 321 on each of the second spring arms 320 to the center of the contact piece 300 can be roughly divided into two distances, the protrusion 410 is set at the same or different circumferential positions on two circular tracks of different diameters at the bottom of the rotary seat 400; when the distance from the protrusion 321 on each of the second spring arms 320 to the center of the contact piece 300 can be roughly divided into three distances, the protrusion 410 is set at the same or different circumferential positions on three circular tracks of different diameters at the bottom of the rotary seat 400.

[0045] Thus, when the rotary seat 400 rotates, the protrusions 410 at the same or different circumferential positions on circular tracks of different diameters come into contact with the protrusions 321 on different second spring arms 320, thereby pushing the second spring arms 320 down, so that the abutting part 322 at the free end of the second spring arm 320 can come into contact with the second connecting piece 220 to form a circuit.

[0046] It is important to understand that, since the first spring arm 310 is always in contact with the first connecting piece 210, the number of second spring arms 320 in contact with each of the second connecting pieces 220 directly affects the number of switching signals that the encoder switch can output. By arranging each of the second spring arms 320 and each of the protrusions 410 in this way, the rotary base 400 can ensure that any one, any number, or all of the second spring arms 320 are in contact with each of the second connecting pieces 220. In an embodiment where four second spring arms 320 are provided, the encoder switch can output up to 16 types of switching signals.

[0047] Further reference Figure 5In some embodiments, the protrusions 410 located in the same circumferential position and adjacent radial positions are connected together. Since the encoder switch is extremely small, that is, the rotary base 400 is extremely small, the protrusions 410 located in the same circumferential position and adjacent radial positions are arranged in this way, which facilitates the injection molding of the rotary base 400 and also improves the structural strength of each protrusion 410, thereby improving the service life of the encoder switch.

[0048] Further reference Figures 2 to 4 and Figure 6 In some embodiments, a plurality of teeth 420 are arranged in a circumferential array on the top of the rotary base 400. A cover 600 is also provided on the top of the base 100. The cover 600 has a through hole through which the rotary base 400 can pass. A ring-shaped third spring arm 610 is provided in the through hole. The third spring arm 610 is positioned directly opposite the ring teeth 420 on the top of the rotary base 400. A positioning part 611 that can be embedded in the teeth 420 is provided on the third spring arm 610. It should be understood that the number of ring teeth 420 on the top of the rotary base 400 is consistent with the number of switching signals that the encoder switch can output, such as the aforementioned 16 types of switching signals, which correspond to 16 teeth 420. By setting a positioning part 611 on the third spring arm 610, the positioning part 611 can be locked on the corresponding tooth position 420 when the rotary seat 400 outputs a switch signal, thereby giving the user sound feedback and tactile feedback, making it easier for the user to judge whether to continue rotating the rotary seat 400, which is conducive to the accurate output of the switch signal.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
