Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figures 1-7 As shown, this utility model provides a dustproof and waterproof wired remote control, including a main body 1 and a main control board 2. The main body 1 includes an upper cover 11 and a lower cover 12. The main control board 2 is installed inside the main body 1. The main control board 2 is provided with a potentiometer 21. The knob of the potentiometer 21 passes through the upper cover 11 and its end is exposed outward. The knob of the potentiometer 21 is fitted with a first sealing ring 22. The top surface of the first sealing ring 22 abuts against the inner wall of the upper cover 11 to achieve a seal between the upper cover 11 and the potentiometer 21. The lower cover 12 is provided with a second sealing ring 121. The top surface of the second sealing ring 121 abuts against the inner wall of the upper cover 11 to achieve a seal between the upper cover 11 and the lower cover 12.

[0029] Furthermore, such as Figures 1-4 As shown, the upper cover 11 extends inwardly with a first insert ring 110, which is press-fitted with the first sealing ring 22, causing the first sealing ring 22 to undergo elastic deformation. The working end width of the first insert ring 110 is smaller than the width of the first sealing ring 22. The knob of the potentiometer 21 includes a rotating shaft 211 and an outer shaft 212, wherein the outer shaft 212 is fixed to the potentiometer 21, and the rotating shaft 211 and the outer shaft 212 are in a sealed rotational fit. The outer shaft 212 passes through the upper cover 11 and is exposed outward. The first sealing ring 22 is sleeved on the outer wall of the outer shaft 212. The upper cover 11 is provided with a first fastener 13 that is fixedly installed with the outer shaft 212.

[0030] Specifically, such as Figures 2-4As shown, the upper cover 11 has a mounting hole for mounting the knob of the potentiometer 21. After the wired remote control is installed, the knob of the potentiometer 21 is exposed through the mounting hole of the upper cover 11. The exposed part includes the rotating shaft 211 and the outer shaft 212 of the knob. The outer shaft 212 is fixedly mounted on the surface of the potentiometer 21. The rotating shaft 211 and the inner wall of the outer shaft 212 are in a sealed rotational fit. At this time, by using the first fastener 13 to fix the outer shaft 212, the position of the potentiometer 21 is stabilized, and the two sides of the first sealing ring 22 can respectively abut and seal against the inner side of the upper cover 11 and the potentiometer 21. In some embodiments, the outer surface of the outer shaft 212 can be provided with threads, and the first fastener 13 can be set as a nut that is threadedly connected to the outer shaft 212. The depth of the first fastener 13 screwed into the outer shaft 212 increases the clamping force of the upper cover 11 and the potentiometer 21 on the first sealing ring 22.

[0031] In the embodiments of this section, such as Figures 3-4 As shown, in order to reduce the depth of the first fastener 13 screwed into the threaded surface of the outer shaft 212 while maintaining the sealing performance, a first insert ring 110 can be provided around the mounting hole of the upper cover 11. When the first fastener 13 is gradually screwed into the threaded surface of the outer shaft 212, the first insert ring 110 simultaneously gradually increases the pressure on the first sealing ring 22, causing the first sealing ring 22 to undergo elastic deformation. At this time, the other side of the first sealing ring 22 is in close contact with the potentiometer 21, and the contact force between the position corresponding to the first insert ring 110 and the potentiometer 21 is higher than that of other positions. When the first fastener 13 is screwed into the threaded surface of the outer shaft 212 to the same depth, this embodiment has a better sealing effect than the embodiment without the first insert ring 110.

[0032] In addition, potentiometers 21 with an outer shaft 212, especially with a threaded outer shaft 212, are quite common in the prior art. At the same time, the sliding fit between the rotating shaft 211 and the outer shaft 212 of the potentiometer 21 is also a technology of the prior art. Its outer shaft 212 is also used to connect the potentiometer 21 to other parts. However, it is worth noting that the potentiometer 21 used in this utility model is a potentiometer 21 with waterproof and dustproof functions. Potentiometers 21 with the same function are also quite common in the prior art, and will not be described in detail here.

[0033] Further, such as Figure 1 , 2As shown in Figures 3 and 5, a second sealing cavity 3 for installing the second sealing ring 121 is formed between the upper cover 11 and the lower cover 12. The upper cover 11 has a first protrusion 31 and a second protrusion 32 extending into the second sealing cavity 3, which respectively form the two side walls of the second sealing cavity 3. The lower cover 12 is provided with a second insert ring 122 at a position corresponding to the second sealing cavity 3. The second insert ring 122 is interference-fitted with the second sealing ring 121, causing the second sealing ring 121 to undergo elastic deformation. The working end width of the second insert ring 122 is smaller than the width of the second sealing ring 121. The lower cover 12 is provided with a support portion 123 on the other side of the second insert ring 122. One side of the main control board 2 abuts against the support portion 123, and the other side abuts against the inside of the upper cover 11.

[0034] Specifically, such as Figure 3 , 5 As shown, after the upper cover 11 and the lower cover 12 are connected and assembled, there is a certain gap between the upper cover 11 and the lower cover 12. An installation cavity for mounting the main control board 2 and a second sealing cavity 3 are formed at the edge between the upper cover 11 and the lower cover 12. Without a seal, the external environment will communicate with the installation cavity through the gap. By installing the second sealing ring 121 in the second sealing cavity 3, the gap can be effectively isolated from the installation cavity. At the same time, the second sealing cavity 3 has a first protrusion 31 on the side close to the installation cavity and a second protrusion 32 on the side away from the installation cavity. It can be seen that the radius of the first protrusion 31 is smaller than the radius of the second protrusion 32. The first protrusion 31 and the second protrusion 32 abut against the lower cover 12 to seal the second sealing cavity 3, thereby improving the sealing effect of the second sealing cavity 3.

[0035] In some embodiments, such as Figure 3 , 5 As shown, by providing a second insert ring 122 extending to the upper cover 11 on the lower cover 12, after the upper cover 11 and the lower cover 12 are combined, the second insert ring 122 applies pressure to the second sealing ring 121, causing the contact portion between the second sealing ring 121 and the second insert ring 122 to be elastically deformed under pressure, while the remaining portion abuts against the inside of the upper cover 11. It can be seen that the pressure on the contact portion between the second sealing ring 121 and the second insert ring 122 is relatively large, and its sealing performance is stronger than that of the embodiment without the second insert ring 122, thus achieving a better sealing effect.

[0036] In addition, such as Figure 5As shown, after the upper cover 11 and the lower cover 12 are combined, a mounting cavity for fixing the main control board 2 is formed. The lower cover forms a support part 123 at the position corresponding to the main control board 2. At this time, one side of the main control board abuts against the support part 123, and the other side abuts against the inner wall of the upper cover 11. In some embodiments, the support part 123 can be elastic, and while supporting the main control board 2, it is elastically squeezed by the main control board 2 to achieve the effect of elastically pressing the main control board 2 against the inner wall of the upper cover 11, thereby improving the stability of the main control board 2 during installation.

[0037] Furthermore, such as Figure 2 As shown, the lower cover 12 is provided with a plurality of second fasteners 23, each of the second fasteners 23 passing through the second sealing cavity 3 and fixedly installed with the upper cover 11, and the second sealing ring 121 is provided with a sealing hole 124 that seals with the second fasteners 23.

[0038] Specifically, the upper cover 11 and the lower cover 12 are assembled together by a second fastener 23, which can be a screw. The screw passes through the lower cover 12, the sealing hole 124 of the second sealing ring 121, and the upper cover 11 in sequence to achieve the installation between the upper cover 11 and the lower cover 12. The sealing hole 124 of the second sealing ring 121 and the screw thread can be used to seal this part. When the second sealing ring 121 is engaged with the screw thread, it can undergo elastic deformation to the upper cover 11, so that more of the second sealing ring is attached to the screw thread, achieving a better sealing effect.

[0039] Furthermore, such as Figure 3 , 5 As shown, the second protrusion 32 extends to one side and covers the side wall of the lower cover 12, forming a joint seam 321 with a corner section between it and the lower cover 12.

[0040] Specifically, in some embodiments, after the upper cover 11 and the lower cover 12 are combined, the gap formed between the upper cover 11 and the lower cover 12 is connected to the second sealing cavity 3. However, in other embodiments, the second protrusion 32 can be extended to the edge of the lower cover 12 and cover the edge of the lower cover 12, thereby forming a joint seam 321 with a corner section between the upper cover 11 and the lower cover 12. Compared with the gap formed between the upper cover 11 and the lower cover 12, the joint seam 321 with a corner section can effectively delay the arrival of moisture and dust into the second sealing cavity 3. In a dusty environment, dust can even accumulate at the corner of the joint seam 321 to naturally form a sealing strip, achieving a better sealing effect.

[0041] Furthermore, such as Figure 1 , 2As shown in Figures 6 and 7, the upper cover 11 is rotatably fitted with a knob cap 10 for fixing it to the knob. The upper cover 11 has a transparent area 101, and the remaining space is a light-blocking area 102. The radius of the transparent area 101 is larger than the radius of the knob cap 10. The main control board 2 is equipped with an LED light, and the transparent area 101 is used for light transmission. The transparent area 101 has at least two light-transmitting parts 103, and each light-transmitting part 103 is located in the area of ​​the transparent area 101 that is wider than the knob cap 10.

[0042] Specifically, during operation, the LED lights on the main control board 2 emit light, which diffuses outward through the transparent area 101 and the knob cap 10. By setting the light-shielding area 102, the emitting area can be better defined, improving the aesthetic effect. When installing the knob cap 10, the rotating shaft 211 of the knob is inserted into the knob cap 10, and the two are installed and fixed by interference fit. On this basis, several light-transmitting parts 103 can be set in the transparent area 101 to enhance its display effect. In some schemes, the light emitted by the LED lights is a single color, such as white. When the rotating shaft 211 on the potentiometer 21 is rotated by the knob cap 10, the LED lights respond to the rotation of the knob cap 10 by flashing in a fast or slow flashing pattern.

[0043] It should be noted that the main control board 2 is connected to the outside via a connecting cable 24. The connecting cable 24 extends outward through the lower cover 12 and is sealed in this part. This sealing can be achieved by applying sealant, such as glass glue. The end of the connecting cable 24 is provided with a plug for connecting to external devices.

[0044] The following is a detailed explanation of the working principle of this utility model;

[0045] External devices can be controlled and adjusted by rotating the knob. In order to ensure normal use in humid and dusty environments, the connection gap between potentiometer 21 and upper cover 11 needs to be sealed by the first sealing ring 22, and the connection gap between upper cover 11 and lower cover 12 needs to be sealed by the second sealing ring 121 to achieve a better sealing effect and ensure that the remote control can be used normally in humid and dusty environments.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
