DETAILED DESCRIPTION

[0029] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0031] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0032] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0033] One aspect of the present application provides an external dial switch, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, one preferred embodiment includes a housing 1, a switch assembly 2, and a sealing cover 3. The housing 1 includes a sealing section 11, a positioning section 12, and a mounting section 13 arranged axially in sequence. The sealing section 11 is located at the outer end of the housing 1. A mounting cavity 111 is provided within the sealing section 11. The switch assembly 2 is mounted within the mounting cavity 111. The sealing cover 3 is mounted outside the sealing section 11 to completely seal the outer end of the housing 1. The sealing cover 3 protects the switch assembly 2 and can be opened to operate the switch assembly 2 for gear adjustment.

[0034] It should be noted that the switch assembly 2 is generally located inside the body 4, and an external control lever protruding from the outside of the body 4 is connected to the switch assembly 2, and the gear position of the switch assembly 2 is indirectly adjusted by adjusting the control lever; when it rains or is near a water source, liquid can easily enter the interior of the switch assembly 2 through the control lever and damage the circuit system; in addition, according to structural principles, the impact force generated when the external control lever is hit is mainly applied to the connection between the adjustment lever and the body 4, and the adjustment lever is easily broken due to its low structural strength, making it impossible to control the switch assembly 2.

[0035] In this embodiment, if Figure 2 and Figure 4 As shown, the sealing section 11 can be installed on the outside of the body 4, and the switch assembly 2 is located inside the installation cavity 111. The enclosed space formed by the sealing cover 3 and the sealing section 11 can effectively prevent external liquids, dust, etc. from entering the installation cavity 111 and affecting the operation of the switch assembly 2. In addition, since the switch assembly 2 is located on the outside of the body 4, the switch assembly 2 can be adjusted without an external joystick.

[0036] It should be known that in order to further improve the sealing effect of the sealing cover 3 on the sealing section 11, a first sealing ring 100 is installed on the sealing section 11. When the sealing cover 3 and the sealing section 11 are sealed together, the first sealing ring 100 is pressed tightly together with the positioning section 12 under the extrusion of the sealing cover 3, so that a seal is formed between the sealing cover 3 and the positioning section 12.

[0037] In this embodiment, if Figure 2 and Figure 3 As shown, the switch assembly 2 includes a mounting plate 21 and a dial switch 22. The dial switch 22 is positioned and installed in the mounting cavity 111. The mounting plate 21 is limitedly installed in the mounting cavity 111 and is located on the outside of the dial switch 22. The mounting plate 21 and the mounting cavity 111 are limited in position to limit the axial position of the dial switch 22 through the limiting cooperation.

[0038] In this embodiment, if Figure 5 and Figure 6 As shown, the dial switch 2 includes a base 221, a dial seat 222 and a dial 223; the base 221 is positioned and matched with the mounting cavity 111, and the dial seat 222 is arranged in the middle of the base 221 for mounting the dial 223; a mounting hole 211 is provided on the mounting plate 21, and the lower end surface of the mounting plate 21 is fitted with the dial seat 222 so that the dial 223 passes through the mounting hole 211 and extends to the outside of the mounting plate 21.

[0039] It should be noted that there are various ways to mount the dial 223 and the dial seat 222. The dial 223 can be slidably mounted on the dial seat 222, or the dial 223 can be rotatably mounted on the dial seat 222. When the dial 223 is slidably mounted on the dial seat 222, the mounting hole 211 can be circular or polygonal. However, to ensure maximum contact between the mounting plate 21 and the dial seat 222, the mounting hole 211 is configured as a straight line. In this case, the length of the mounting hole 211 must be no less than the adjustment range of the dial 223. When the dial 223 is rotatably mounted on the dial seat 222, there is no fixed requirement for the shape of the mounting hole 211; it only needs to ensure that the dial 223 can rotate within the mounting hole 211.

[0040] It is understandable that the mounting hole 211 is in the shape of a straight line and can limit the dial 223 in the circumferential direction; in addition, in order to facilitate observation of the gear position, different gear position marks can be set on the upper end surface of the mounting plate 21 for identification.

[0041] It can also be understood that in order to more conveniently adjust the dial 223, the top of the dial 223 should extend upward and protrude to the outside of the installation cavity 111, so that the position of the dial 200 can be immediately observed when the sealing cover 3 is opened; when installing the sealing cover 3, it is necessary to ensure that the dial 223 does not collide with the installation cover 3 to avoid damaging the dial 223.

[0042] In this embodiment, if Figure 7 and Figure 8 As shown, a limiting structure is provided on the mounting plate 211 or the mounting cavity 111 to provide an interference fit between the mounting plate 21 and the inner wall of the mounting cavity 111, thereby limiting the mounting plate 21's position within the mounting cavity 111. The principle of interference fit is well known to those skilled in the art and will not be elaborated on in detail here. There are various interference fit methods, including but not limited to the following two.

[0043] The first method is to make an overall interference fit between the side of the mounting plate 21 and the inner wall of the mounting cavity 111. The mounting plate 21 is inserted into the mounting cavity 11, and the side of the mounting plate 21 is interference fit into the inner wall of the mounting cavity 111 for fixed positioning.

[0044] The second type: a plurality of spaced limit blocks 212 are provided on the side of the mounting plate 21 along the circumferential direction, or a plurality of spaced limit blocks 212 are provided on the side wall of the mounting cavity 111 along the circumferential direction; when the mounting plate 21 is installed inside the mounting cavity 111, an interference fit is performed between the mounting plate 21 and the mounting cavity 111 through the limit blocks 212, so that the mounting plate 21 is limitedly installed in the mounting cavity 111.

[0045] It should be known that the first interference fit method mentioned above is to fit between the entire surface and the surface, which is more difficult to disassemble the mounting plate 21, while the second interference fit method is to fit between the surface and the spaced limit blocks 212, which is not only convenient for disassembly, but also can increase the deformation angle of the limit blocks 212 to make the interference fit more stable.

[0046] In this embodiment, if Figure 3 and Figure 4 As shown, the mounting plate 21 and the base 221 are installed inside the mounting cavity 111 by positioning and matching. There are many ways of positioning and matching, including but not limited to the following two.

[0047] The first type: the sides of the mounting plate 21 and the base 221 are both provided with positioning grooves 400 , the side walls of the mounting cavity 111 are provided with positioning blocks 401 , and the mounting plate 21 and the base 221 are both positioned and matched with the positioning grooves 400 and the positioning blocks 401 .

[0048] The second type: the sides of the mounting plate 21 and the base 221 are both provided with positioning blocks 401 , the side walls of the mounting cavity 111 are provided with positioning grooves 400 , and the mounting plate 21 and the base 221 are both positioned and matched with the positioning blocks 401 and the positioning grooves 400 .

[0049] It should be noted that when installing the mounting plate 21 and the base 223 in the mounting cavity 111, the positioning grooves 400 and the positioning blocks 401 are first aligned, and then the positioning blocks 401 are inserted into the corresponding positioning grooves 400 to achieve a positioning fit. In addition, the positioning fit can also be used to limit the circumferential position of the base 221.

[0050] It is understandable that in order to reduce the number of positioning fits used, the positioning grooves 400 on the mounting plate 21 and the base 221 can be set at the same position, or the positioning blocks 401 on the mounting plate 21 and the base 221 can be set at the same position.

[0051] In this embodiment, if Figure 1 and Figure 2 As shown, the interior of the sealing cover 3 and the exterior of the sealing section 11 are provided with mating threads, and the sealing cover 3 is mounted on the outside of the sealing section 11 through the threaded engagement. An anti-slip structure 31 is provided on the outside of the sealing cover 3 to increase friction between the finger and the sealing cover 3. The specific specifications of the threads and the principles of thread engagement are well known to those skilled in the art and will not be elaborated on here.

[0052] It should be known that there are many ways to set up the anti-slip structure 31. It can be to set multiple grooves or anti-slip strips along the circumferential direction on the outside of the sealing cover 3, or to set knurling along the circumferential direction on the outside of the sealing cover 3, or to lay an anti-slip pad along the circumferential direction on the outside of the sealing cover 3. Any structure that can increase the friction between the finger and the sealing cover 3 can meet the needs.

[0053] In this embodiment, if Figure 1 and Figure 2 As shown, a fixing member 300 is installed on the installation section 13 , and the installation section 13 and the fixing member 300 are connected by threaded fitting, so that a clamping cavity 301 for installing the housing 1 is formed between the fixing member 300 and the positioning section 12 .

[0054] It should be understood that the size of the clamping cavity 301 is determined by the relative distance between the fixing member 300 and the positioning section 12 , and the size of the clamping cavity 301 can be adjusted by rotating the fixing member 300 .

[0055] In this embodiment, if Figure 1 and Figure 2 As shown, a second sealing ring 101 is installed on the installation section 13. When the fixing member 300 moves toward the positioning section 12, the fixing member 300 squeezes the second sealing ring 101 into the clamping cavity 301 and seals the external DIP switch.

[0056] It should be known that the first sealing ring 100 and the second sealing ring 101 are made of materials including but not limited to rubber with good ductility and wear resistance. The specific specifications and sealing principles of the sealing rings are well known to those skilled in the art and will not be elaborated here.

[0057] In this embodiment, if Figure 6 As shown, a through hole 131 is provided inside the mounting section 13, and the through hole 131 passes through the mounting section 13 and the positioning section 12 in sequence and is connected to the mounting cavity 111. The switch component 2 conducts electrical signals through the through hole 131. The specific circuit connection principle is a well-known technology for those skilled in the art, so it will not be elaborated here.

[0058] Another aspect of the present application provides a lighting device, wherein a preferred embodiment includes the above-mentioned external dip switch, which can be installed on the body 4 of the lighting device through the mounting section 13 so that the sealing section 11 extends to the outside of the body 4.

[0059] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application.
