Description

Technical Field

[0001] This utility model relates to the field of rotary encoder switch technology, and more specifically, to a waterproof and dustproof rotary encoder switch. Background Technology

[0002] Waterproof and dustproof rotary encoder switches are electronic components with protective functions. They are mainly used to detect the position, angle or speed of mechanical rotation and convert these physical quantities into electrical signal outputs. These switches are usually used in harsh environments (such as humid and dusty places), so they need to have good sealing performance. They are widely used in industrial automation, instrumentation, consumer electronics and other fields.

[0003] However, the installation process of rotary encoder switches is cumbersome, increasing installation costs and time. During installation and use, it is difficult to ensure the seal between the switch base and the housing, which can easily lead to moisture and dust entering the switch, affecting its performance and lifespan.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In response to the problems in related technologies, this utility model proposes a waterproof and dustproof rotary encoder switch to solve the problems of cumbersome installation process and poor sealing between the switch base and the housing.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A waterproof and dustproof rotary encoder switch includes a rotary encoder switch housing. A mounting assembly is provided on the lower part of the rotary encoder switch housing. The mounting assembly includes mounting holes evenly distributed on the lower part of the rotary encoder switch housing. Restricting springs are arranged opposite each other inside the mounting holes. One end of the restricting spring contacts a switch base. One end of the switch base is engaged with one end inside the mounting hole. A sealing assembly is provided on the opposite side of the switch base and the rotary encoder switch housing.

[0008] Furthermore, in order to better improve the waterproof and dustproof properties of the rotary encoder switch, the sealing assembly includes a sealing groove on the side opposite to the switch base and the rotary encoder switch housing. A sealing block is installed inside the sealing groove, and multiple limiting plates are provided on the sealing block and on both sides of the inner wall of the sealing groove, with one end of the limiting plates in contact with each other.

[0009] Furthermore, in order to better protect the pins and reduce pin damage, multiple pins are provided on both sides of the switch base, and the surface of the pins is sequentially coated with a graphene conductive coating and a micro-nano composite conductive coating.

[0010] Furthermore, in order to make better use of the rotary encoder switch, a rotating hole is provided on the top of the rotary encoder switch housing, and a rotary knob is installed inside the rotating hole.

[0011] Furthermore, in order to better improve the sealing of the rotary knob gap, a protective groove is provided on the inner wall of the rotary hole and the surface of the rotary knob, and a sealing bearing is installed inside the protective groove. An auxiliary groove is provided on one end face of the rotary knob.

[0012] Furthermore, in order to better assist in heat dissipation of the rotary encoder switch, heat dissipation vents are symmetrically opened on both sides of the rotary encoder switch housing. Filter covers are installed inside the heat dissipation vents, and filter screens and activated carbon screens are installed inside the filter covers.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) The installation components set in the rotary encoder switch housing ensure the compactness and stability of the installation structure. There is no need to add additional complex connectors or support structures, avoiding installation errors and failure risks caused by inaccurate component assembly. This improves the assembly quality and overall performance of the equipment. At the same time, the sealing components set in the rotary encoder switch housing can not only form a sealing barrier to effectively block the intrusion path of external moisture and dust, but also improve the tightness between the rotary encoder switch housing and the switch base. The contact further enhances the sealing effect, making the sealing performance of the entire switch more stable and reliable. This ensures that the internal components of the switch are not affected by external environmental factors, and guarantees its normal operation and service life.

[0015] (2) By setting a sealed bearing between the rotating hole and the rotating knob, the sealing problem caused by the gap between the rotating knob and the rotating hole is not only effectively solved, but also the rotating knob can maintain a good sealing state during rotation, preventing external impurities from entering the switch from the rotating part. At the same time, the filter cover, filter screen plate and activated carbon screen plate set in the rotary encoder switch housing exchange heat with the external air, effectively reducing the temperature inside the switch, avoiding the degradation or damage of the component performance due to overheating, and also preventing external dust and debris from entering the switch, thus improving the stability and reliability of the rotary encoder switch during long-term operation.

[0016] (3) The graphene conductive coating and micro-nano composite conductive coating set on the pins not only have excellent conductivity, but also have a certain protective effect, which enhances the isolation effect between the pins and the external environment, reduces the risk of moisture and dust penetration caused by the gap between the pins and the external connection parts, and can further improve the reliability and safety of the rotary encoder switch.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figures 1-7 As shown, a waterproof and dustproof rotary encoder switch according to an embodiment of the present invention includes a rotary encoder switch housing 1, which is used to protect internal components from the influence of the external environment and ensure the mechanical stability of the entire device. A mounting assembly 2 is provided below the rotary encoder switch housing 1. The mounting assembly 2 includes mounting holes 201 evenly distributed below the rotary encoder switch housing 1 for mounting a switch base 203. A limiting spring 202 is provided inside the mounting holes 201 to limit the switch base 203. One end of the limiting spring 202 contacts the switch base 203 for auxiliary sealing of the rotary encoder switch housing 1. One end of the switch base 203 is engaged with one end inside the mounting hole 201.

[0030] A rotating hole 7 is provided on the top of the rotary encoder switch housing 1. A rotary knob 8 is installed inside the rotating hole 7. The rotary knob 8 is used to change the state of the encoder. The surface of the rotary knob 8 is equipped with an encoder (mechanical) and contacts (not shown in the figure) to generate different state signals. The contacts are electrically connected to a circuit board (not shown in the figure). The encoder can be optical in actual use. When using an optical encoder, the contacts can be replaced with a light source and a light sensor. The contacts are used to connect or disconnect and generate corresponding electrical signals. The circuit board is an electronic component for receiving signals from the contacts and converting these signals into data that can be used to calculate the rotation direction and speed.

[0031] The inner wall of the rotating hole 7 and the surface of the rotating knob 8 are provided with protective grooves 9 for installing the sealing bearing 10. The sealing bearing 10 is installed inside the protective groove 9 to seal the gap between the rotating hole 7 and the rotating knob 8. An auxiliary groove 11 is provided on one end face of the rotating knob 8. Three pins 4 are provided on both sides of the switch base 203 for connecting other components. The pins 4 are electrically connected to the circuit board in actual use (not shown in the figure). The surface of the pins 4 is sequentially provided with a graphene conductive coating 5 and a micro-nano composite conductive coating 6 for protecting the pins 4. The graphene conductive coating 5 and the micro-nano composite conductive coating 6 can be replaced with other coatings according to the actual situation in actual use, so they are not described in detail. The graphene conductive coating 5 and the micro-nano composite conductive coating 6 are not existing technologies, so they are not described in detail.

[0032] Example 2:

[0033] like Figures 1-2 , Figure 5 , Figure 6 As shown, a waterproof and dustproof rotary encoder switch according to an embodiment of the present invention has a sealing component 3 on the opposite side of the switch base 203 and the rotary encoder switch housing 1. The sealing component 3 includes a sealing groove 301 on the opposite side of the switch base 203 and the rotary encoder switch housing 1 for installing a sealing block 302. The sealing block 302 is installed inside the sealing groove 301 to assist in sealing the gap between the switch base 203 and the rotary encoder switch housing 1, which is beneficial to improve waterproof and dustproof properties. The sealing block 302 is coated with a corrosion-resistant coating, an anti-oxidation coating, and a wear-resistant coating. The corrosion-resistant coating, anti-oxidation coating, and wear-resistant coating are not described in detail in the prior art. Multiple limiting pieces 303 are provided on the sealing block 302 and on both sides of the inner wall of the sealing groove 301, and one end of the limiting pieces 303 is in contact with each other.

[0034] The rotary encoder switch housing 1 has symmetrical heat dissipation vents on both sides for auxiliary heat dissipation. A filter cover 12 is installed inside the heat dissipation vents, which is a U-shaped frame for installing the filter screen plate 13 and the activated carbon screen plate 14. The filter screen plate 13 and the activated carbon screen plate 14 are installed inside the filter cover 12 for treating the incoming gas and the moisture in the gas. The filter screen plate 13 and the activated carbon screen plate 14 can be replaced with other materials or structures according to the actual situation in actual use, so they will not be described in detail. The filter cover 12, the filter screen plate 13 and the activated carbon screen plate 14 are not existing technologies, so they will not be described in detail.

[0035] The rotary encoder switch housing 1, switch base 203, rotary knob 8, pin 4, encoder, contacts, and circuit board are existing technologies and will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In summary, with the help of the above-mentioned technical solution of this utility model, during installation, the operator places the rotary encoder switch housing 1 in the installation position, aligning the switch base 203 with the mounting hole 201. The limiting spring 202 restricts the switch base 203, fixing it within the mounting hole 201, thereby ensuring a compact and stable installation structure for the rotary encoder switch. This eliminates the need for additional complex connectors or support structures, reducing installation errors and the risk of malfunction.

[0038] After the rotary encoder switch housing 1 and the switch base 203 are installed in place, the sealing block 302 is connected to the switch base 203 and the rotary encoder switch housing 1 through the sealing groove 301. The sealing block 302 and the sealing groove 301 are restricted by the limiting piece 303, so that a sealing barrier is formed between the switch base 203 and the rotary encoder switch housing 1, effectively blocking the intrusion path of external moisture and dust, while improving the tightness between the rotary encoder switch housing 1 and the switch base 203 and enhancing the sealing effect.

[0039] After installation, pin 4 is connected to the structure to be connected. The graphene conductive coating 5 and micro-nano composite conductive coating 6 on pin 4 not only have excellent conductivity, but also have a certain protective effect, which enhances the isolation effect between pin 4 and the external environment and reduces the risk of moisture and dust penetration caused by gaps between pin 4 and external connection parts.

[0040] When the user rotates the rotary knob 8, the rotary knob 8 drives the internal encoder (mechanical) and contacts (not shown in the figure) to rotate. The contacts are electrically connected to a circuit board (not shown in the figure). In actual use, the encoder can be optical. The contacts are used to connect or disconnect, generating corresponding electrical signals. The circuit board converts these signals into data that can be used to calculate the rotation direction and speed.

[0041] The rotary encoder switch housing 1 uses a filter cover 12 installed inside the heat dissipation vent, and a filter screen 13 and an activated carbon screen 14 installed inside the filter cover 12. This allows external air to enter the housing 1 through the heat dissipation vent for heat exchange, effectively reducing the internal temperature of the switch. At the same time, the filter screen 13 and the activated carbon screen 14 can filter the incoming air, preventing external dust and debris from entering the switch, thus improving the stability and reliability of the rotary encoder switch during long-term operation.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
