Description

Technical Field

[0001] This utility model relates to the field of rotary switches, and in particular to a multifunctional rotary switch. Background Technology

[0002] In the field of electronic equipment and instrumentation, color screens and digital tube displays are widely used. Color screens, with their vibrant colors and rich information display capabilities, meet the high requirements of visual effects and information transmission in scenarios such as consumer electronics and smart devices. Digital tubes, on the other hand, occupy an important position in industrial control and basic instrumentation due to their high stability and cost-effectiveness, and can accurately display key data such as numbers and simple symbols.

[0003] Traditional knobs, as classic human-computer interaction components, have historically been effective in assisting users in controlling device functions. However, with the rapid advancement of display technology, color screens and digital tubes have become increasingly diverse in size. The design limitations of traditional knobs have gradually become apparent. From a mechanical compatibility perspective, their size specifications and fixing structure are difficult to match with the casings and installation layouts of display devices of different sizes, hindering flexible installation. Utility Model Content

[0004] To improve efficiency, this utility model provides a multi-functional rotary switch.

[0005] This utility model provides a technical solution that adopts the following approach:

[0006] A multi-functional rotary switch, comprising:

[0007] Connector;

[0008] Mounting base, provided on the connector;

[0009] The mounting slots are provided in multiple ways, and the multiple mounting slots are configured with different shapes to accommodate different display devices. The multiple mounting slots are stacked together.

[0010] A PCB board is used to set the mounting base. The PCB board is provided with metal connecting pieces that pass through multiple mounting slots.

[0011] Different shaped color screens or digital tube display devices are installed in their corresponding mounting slots, allowing the display devices to abut against the metal connecting pieces, thus establishing electrical conductivity between the display devices and the PCB board. When different shaped color screens or digital tubes need to be installed in the mounting slots, the corresponding mounting slots can be selected according to the different shapes of the display devices. This improves product compatibility, makes the overall design more reasonable, and can meet the needs of different customers without requiring multiple mold openings.

[0012] Preferably, the two mounting slots are a circular slot and a rectangular slot, the diameter of the circular slot is greater than the length of the rectangular slot, the two end faces of the circular slot and the rectangular slot coincide along their own depth direction, and the diameter of the circular slot is less than the diagonal length of the rectangular slot.

[0013] The overlapping of the two sides of the circular and rectangular grooves results in most of their spaces overlapping, reducing the space required for multiple overlapping grooves. This helps to reduce the overall thickness of the button and makes the internal layout of the button more reasonable.

[0014] Preferably, one of the mounting grooves is a large circular groove, the opening of which covers the side of the rectangular groove opening away from the connector, and the diameter of the large circular groove is larger than the diameter of the circular groove.

[0015] The large circular slot can be used to install color screens or digital tubes with a large area. The large area of ​​the circular slot allows the top wall of the slot to restrict the installation of the digital tube, which helps to prevent the digital tube from falling into the rectangular slot and makes the arrangement of multiple mounting slots inside the button more reasonable.

[0016] Preferably, the circular groove is provided with a limiting part to accommodate the circular color screen. The limiting part is recessed into the inner wall of the circular groove in a direction away from the center of the circular groove so as to accommodate the protruding part of the color screen.

[0017] The limiting part works in conjunction with the color screen to restrict the rotation of the color screen within the circular groove, which helps to improve the stability of the circular color screen when it is installed in the circular groove.

[0018] Preferably, the mounting base is further provided with a pressure ring, which is detachably disposed in a large circular groove, and the mounting base is covered with a top cover, which abuts against the pressure ring.

[0019] When a color screen is installed in a circular or rectangular groove, the pressure ring can hold the color screen in place, preventing it from falling off the groove and sliding into the larger circular groove. This helps improve the stability of the color screen installation and makes it less likely for the color screen to separate from the groove.

[0020] Preferably, the connector includes a connecting part and a mounting boss. The mounting base is disposed on and covers the mounting boss. The connecting part is integrally connected to the mounting boss. A drainage channel is provided between the connecting part and the mounting boss. A drainage outlet is provided at the bottom of the drainage channel. The drainage outlet avoids the connection between the connecting part and the PCB board.

[0021] The mounting boss enhances the tightness and stability of the connection between the mounting base and the connector, making the mounting base less prone to wobbling. Simultaneously, the combination of the drainage channel and the drain outlet ensures that when water is splashed onto the rotary switch, it flows from the drainage channel to the drain outlet and out, reducing water accumulation and minimizing the risk of corrosion of internal parts.

[0022] Preferably, the cross-section of the drainage channel is semi-circular.

[0023] The semi-circular drainage channel helps reduce water accumulation and makes it easier for water to drain.

[0024] In summary, this utility model has the following beneficial technical effects:

[0025] Different shaped color screens or digital tube display devices are installed in their corresponding mounting slots, allowing the display devices to abut against the metal connecting pieces, thus establishing electrical conductivity between the display devices and the PCB board. When different shaped color screens or digital tubes need to be installed in the mounting slots, the corresponding mounting slots can be selected according to the different shapes of the display devices. This improves product compatibility, makes the overall design more reasonable, and can meet the needs of different customers without requiring multiple mold openings. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0032] This utility model discloses a multifunctional rotary switch.

[0033] Reference Figure 1 as well as Figure 2 A multi-functional rotary switch, comprising:

[0034] Connector 1;

[0035] Mounting base 2 is provided on connecting base 1;

[0036] The mounting slots are provided in multiple ways, with different shapes to accommodate different display devices, and the multiple mounting slots are stacked together.

[0037] PCB board 3 is used to set the mounting base 2. PCB board 3 is provided with metal connecting pieces that pass through multiple mounting slots.

[0038] Different shaped color screens 14 or digital tube display devices are installed in the mounting slots corresponding to their shapes, so that the display devices abut against the metal connecting pieces, thereby making the display devices conductive to the PCB board 3. When different shaped color screens 14 or digital tubes need to be installed in the mounting slots, the corresponding mounting slots can be selected according to the different shapes of the display devices. This helps to improve product compatibility, makes the overall design more reasonable, and can meet the problems of different customers without multiple mold openings, thus reducing costs.

[0039] Reference Figure 3 as well as Figure 4 In this embodiment, the two mounting slots are a circular slot 4 and a rectangular slot 5, respectively. The diameter of the circular slot 4 is greater than the length of the rectangular slot 5. The two end faces of the circular slot 4 and the rectangular slot 5 along their own depth direction coincide, respectively. The diameter of the circular slot 4 is less than the diagonal length of the rectangular slot 5.

[0040] The overlapping of the two end faces of the circular groove 4 and the rectangular groove 5 results in most of their spaces overlapping, reducing the space required for multiple overlapping grooves. This helps to reduce the overall thickness of the button, thereby improving the utilization rate of the internal space of each groove and making the internal structure of the rotary switch more reasonable.

[0041] Reference Figure 3 as well as Figure 4 In this embodiment, one of the mounting slots is a large circular slot 6. The opening of the large circular slot 6 covers the side of the rectangular slot 5 away from the connecting seat 1. The diameter of the large circular slot 6 is larger than the diameter of the circular slot 4.

[0042] The large circular slot 6 can be used to install a color screen 14 or a digital tube with a large installation area. The large area of ​​the circular slot 6 allows the top wall of the circular slot 4 to restrict the installation of the digital tube, which helps to prevent the digital tube from falling into the rectangular slot 5. This makes the arrangement of multiple installation slots inside the button more reasonable and reduces the problem of excessive thickness of the device caused by the arrangement of multiple slots.

[0043] Reference Figure 3 as well as Figure 4 In this embodiment, the circular groove 4 is adapted to the circular color screen 14 and is provided with a limiting part 7. The limiting part 7 is recessed into the inner wall of the circular groove 4 in a direction away from the center of the circular groove 4 so as to provide for the protruding part of the color screen 14.

[0044] The limiting part 7, in accordance with the shape of the color screen 14, can limit the rotation of the color screen 14 within the circular groove 4, thereby improving the stability of the circular color screen 14 when installed within the circular groove 4 and enhancing the user experience.

[0045] Reference Figure 3 as well as Figure 4 In this embodiment, the mounting base 2 is also provided with a pressure ring 8, which is detachably disposed in the large circular groove 6. The mounting base 2 is covered with a top cover 9, which abuts against the pressure ring 8.

[0046] When a color screen 14 is installed in the circular groove 4 or the rectangular groove 5, the pressure ring 8 can press down on the color screen 14 to prevent the color screen 14 from falling off from the circular groove 4 or the rectangular groove 5 and sliding into the large circular groove 6. This helps to improve the stability of the installation of the color screen 14, making it less likely for the color screen 14 installed in the groove to separate from the circular groove 4 or the rectangular groove 5.

[0047] Reference Figure 3 as well as Figure 4 In this embodiment, the connector 1 includes a connector 11 and a mounting boss 10. The mounting 2 is disposed on the mounting boss 10 and covers the mounting boss 10. The connector 11 is integrally connected to the mounting boss 10. A drainage channel 12 is provided between the connector 11 and the mounting boss 10. A drainage outlet 13 is provided at the bottom of the drainage channel 12. The drainage outlet 13 avoids the connection between the connector 11 and the PCB board 3.

[0048] The mounting boss 10 improves the tightness and stability of the connection between the mounting base 2 and the connecting base 1, making the mounting base 2 less prone to shaking. At the same time, the cooperation between the drainage channel 12 and the drain outlet 13 allows water to flow from the drainage channel 12 to the drain outlet 13 and out when water is splashed on the rotary switch, which helps to reduce the accumulation of water and prevent corrosion of the internal parts of the rotary switch.

[0049] Reference Figure 3 as well as Figure 4 In this embodiment, the cross-section of the drainage channel 12 is semi-circular.

[0050] The semi-circular drainage channel 12 helps to reduce the accumulation of water in the drainage channel 12, making it easier for the water to drain.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
