Description

Technical Field

[0001] This invention belongs to the field of switches, specifically relating to a rotary switch. Background Technology

[0002] Existing switch knob structures mainly include the following types: 1. Button type, which controls the switch opening and closing by pressing; 2. Rotary type, which controls the switch opening and closing and encoder gear adjustment by rotating; 3. Toggle type, which controls the switch opening and closing by toggling the switch position. These three existing technologies have the following disadvantages: 1. Rotary and toggle types have the following disadvantages: a. Limited encoding function, only able to control the simple opening and closing of the switch; b. Unable to achieve encoder stop or control encoder gear adjustment for special functions. 2. Rotary type has the following disadvantages: Unable to achieve encoder stop or control encoder gear adjustment for special functions. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a rotary switch that facilitates the customization of special functions and / or the division of gear positions, and the special functions have at least two triggering conditions, thereby increasing the difficulty of triggering special functions while ensuring high triggering stability.

[0004] The present invention provides a rotary switch, including a knob, a knob base, and a stop assembly. The knob is rotatably mounted on the knob base. An annular groove coaxial with the knob's rotation axis is provided on the side of the knob facing the knob base. At least one stop block is provided in the annular groove. The stop assembly includes an operating block and a stop pin connected to each other. The operating block drives the stop pin to disengage from or embed into the annular groove.

[0005] Furthermore, the operating block and the stop pin move linearly parallel to the knob's rotation axis, and the linear movement of the operating block causes the stop pin to disengage from or engage with the annular groove.

[0006] Furthermore, the stop assembly also includes an elastic element that drives the operating block to always be close to the annular groove.

[0007] Furthermore, the stop assembly moves linearly to the knob seat or rotary switch mounting position.

[0008] Furthermore, the knob includes a knob body and a rotating shaft, and the annular groove is disposed on the end face of the knob body.

[0009] Furthermore, the knob body and the pivot are detachably connected.

[0010] The invention also includes a switch body connected to the other end of the rotating shaft, the switch body being fixedly mounted on the knob base.

[0011] Furthermore, the knob base is provided with a locking groove, and the switch body is locked in the locking groove.

[0012] Furthermore, contacts are provided at corresponding positions on the switch body and the operating block, and when the stop pin disengages from the annular groove, the contacts on the operating block can make contact with the contacts on the switch body.

[0013] Furthermore, when the operating block is in the lower limit position, the contact on the operating block contacts the contact on the switch body.

[0014] The beneficial effects of this invention are that it achieves two working states—stopping and unlocking—by setting an operable stop component. In the stopped state, the stop pin is embedded in the annular groove, allowing the knob to rotate, and the annular groove slides relative to the stop pin during rotation. However, when the knob reaches the stop block position, the knob cannot continue to rotate, as the stop pin and stop block mutually limit each other, preventing the knob from rotating into that position. In the unlocking state, the stop pin disengages from the annular groove, allowing the knob to rotate 360° without restriction.

[0015] Therefore, by setting special purposes for the restricted position of the knob, the rotary switch can achieve multiple functions. That is, the unrestricted range of the knob can be set to the normal gear function, and the restricted position of the knob can be set to the special function. In addition, when the stop pin is embedded in the annular groove by default, this special function requires two operations to trigger. That is, the operator needs to move the control block and then turn the knob to trigger the special function, so as to avoid accidental activation of the special function.

[0016] Furthermore, when two or more stop blocks are installed within the annular groove, in addition to the aforementioned multi-functionality, the normal gear positions can also be zoned. Alternatively, only the gear positions can be zoned. Taking two stop blocks as an example, the two stop blocks divide the annular groove into two disconnected arc-shaped grooves. These arc-shaped grooves represent two independent permissible ranges of motion, which can be divided into a low gear and a high gear. The restricted areas of the two stop blocks can be set as two special function positions. When the knob needs to be moved from the low gear to the high gear, it must pass through one of these special function positions; that is, the operator must control the operating block to switch from the low gear to the high gear.

[0017] The rotary switch provided by this invention can facilitate the customization of special functions and / or the division of gear positions. The special functions have at least two triggering conditions, which increases the difficulty of triggering special functions while ensuring high triggering stability. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0035] As attached Figure 1-11 As shown, the present invention provides a rotary switch, including a knob 1, a knob base 2, and a stop assembly 3. The knob 1 is rotatably mounted on the knob base 2. The knob 1 has an annular groove 111 coaxial with the rotation axis of the knob 1 on the side facing the knob base 2. At least one stop block 112 is provided in the annular groove 111. The stop assembly 3 includes an operating block 31 and a stop pin 32 connected to each other. The operating block 31 drives the stop pin 32 to disengage from or embed into the annular groove 111.

[0036] This invention achieves two working states—stopping and unlocking—by setting an operable stop component 3, such as... Figure 4 As shown, in the stopped state, the stop pin 32 is embedded in the annular groove 111, and the knob 1 can rotate at this time. During rotation, the annular groove 111 slides relative to the stop pin 32. However, when the knob 1 is turned to the stop block 112 position, the knob 1 cannot continue to rotate. The stop pin 32 and the stop block 112 mutually limit each other, preventing the knob 1 from rotating into that position. Figure 3 As shown, in the unlocked state, the stop pin 32 disengages from the annular groove 111, at which time the knob 1 can rotate 360° without restriction. When always in the unlocked state, this rotary switch can be used as a regular selector switch.

[0037] Therefore, by setting a special purpose for the restricted position of knob 1, the rotary switch can achieve multiple functions. That is, the unrestricted range of knob 1 can be set to the normal gear function, and the restricted position of knob 1 can be set to a special function. In addition, when the stop pin 32 is embedded in the annular groove 111 by default, this special function requires two operations to be triggered. That is, the operator needs to move the control block 31 and then rotate knob 1 to trigger the special function, so as to avoid accidental activation of the special function.

[0038] Furthermore, when two or more stop blocks 112 are provided within the annular groove 111, in addition to the aforementioned multi-functionality, normal gear positions can also be zoned. Alternatively, only the gear positions can be zoned. Taking two stop blocks 112 as an example, the two stop blocks 112 divide the annular groove 111 into two disconnected arc-shaped grooves. These arc-shaped grooves represent two independent allowable ranges of motion, which can be divided into a low gear and a high gear. The restricted areas of the two stop blocks 112 can be set as two special function positions. When the knob 1 needs to move from the low gear to the high gear, it must pass through a special function position; that is, the operator must control the operating block 31 to switch from the low gear to the high gear.

[0039] Alternatively, a limiting hole that mates with the stop pin 32 can be provided on the stop block 112, or when two or more stop blocks 112 are provided, the distance between two adjacent stop blocks 112 can be adapted to the diameter of the stop pin 32. In this way, the knob 1 can be stopped at the stop block 112 position, that is, the knob 1 is stopped at a special function position, which further improves the application of the rotary switch.

[0040] Special functions can be encoded as device data self-destruction, radio silence, reset, encryption, unlocking, etc.

[0041] In one embodiment, the operating block 31 and the stop pin 32 move linearly parallel to the rotation axis of the knob 1. The linear movement of the operating block 31 causes the stop pin 32 to disengage from or embed into the annular groove 111, thereby simplifying the operation and movement of the stop assembly 3.

[0042] In one embodiment, the stop assembly 3 further includes an elastic element 33 that drives the operating block 31 to always be close to the annular groove 111. In this way, the stop pin 32 can be initially embedded in the annular groove 111. When special functions are required, the operator needs to always control the operating block 31 away from the annular groove 111, increasing the difficulty of triggering special functions and reducing the possibility of accidental activation. The elastic element 33 is preferably a spring.

[0043] In one embodiment, the stop component 3 moves linearly on the knob seat 2 or the rotary switch mounting position. In one embodiment, the rotary switch mounting position is on the side wall of the housing 4, and the knob seat 2 and knob 1 are mounted on the upper end of the housing 4. A sliding groove 41 for the stop component 3 is also provided on the side wall connecting the housing 4 to the upper end, allowing the stop component 3 to slide automatically within the sliding groove 41. This ensures the size of the operating block 31, facilitating operator control of the operating block 31. In another embodiment, the operating block 31 can also be directly slidably mounted on the knob seat 2 to achieve the same function.

[0044] In one embodiment, the knob 1 includes a knob body 11 and a rotating shaft 12. An annular groove 111 is provided on the end face of the knob body 11. Rotation of the rotating shaft 12 triggers different gear positions and special function positions. The knob body 11 and the rotating shaft 12 are detachably connected, preferably by a key connection, facilitating the replacement of the knob body 11 with knob bodies 11 having different numbers of stop blocks 112. A gear position mark 113 is preferably provided on the end face of the knob body 11 for easy identification and operation by the operator.

[0045] In one embodiment, the invention further includes a switch body 6 connected to the other end of the rotating shaft 12. The switch body 6 is a device for triggering different gear positions and special function positions. Rotation of the rotating shaft 12 triggers different gear positions of the switch body 6. The switch body 6 is fixedly mounted on the knob base 2. In this embodiment, the knob base 2 is provided with a locking groove 21, and the switch body 6 is locked in the locking groove 21, facilitating the assembly and disassembly of the switch body 6.

[0046] In one embodiment, contacts are provided at corresponding positions on the switch body 6 and the operating block 31. When the stop pin 32 disengages from the annular groove 111, the contacts on the operating block 31 can contact the contacts on the switch body 6. In this embodiment, it can be set that the two contacts can only be in contact to trigger the special function after the operating block 31 moves away from the annular groove 111 and reaches the lower limit distance. That is, a triggering condition is added for the special gear, which requires the operating block 31 to move away from the limit distance of the annular groove 111. This further increases the difficulty of triggering the special gear without affecting the triggering stability of the special gear.

[0047] like Figure 8-11 As shown, the rotary switch installation method provided by the present invention includes the following steps:

[0048] like Figure 8 As shown, step one: place the switch body 6 connected to the rotating shaft 12 on the rotary switch mounting position of the housing 4;

[0049] like Figure 9 As shown, step two: install the stop assembly 3 into the sliding groove 41 of the housing 4;

[0050] like Figure 10 As shown, step three: install the knob base 2 onto the rotary switch mounting position using fasteners 5, at which point the switch body 6 and the stop assembly 3 are limited;

[0051] like Figure 11 As shown, step four: install the knob body 11 onto the rotating shaft 12.

[0052] The rotary switch provided by this invention is extremely convenient and quick to install. When the stop component 3 is slidably set in the knob seat 2, the installation can be completed by simply looking at one fastener 5.
