Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a remote switch based on LORA. Background Technology

[0002] LoRa is a low-power local area network wireless standard designed to resolve the contradiction between power consumption and transmission range limitations. Generally, low power consumption results in shorter transmission distances, while high power consumption results in longer transmission distances. By developing LoRa technology, the technical problem of achieving longer transmission distances than other wireless methods under the same power consumption conditions has been solved, thus achieving a balance between low power consumption and long range.

[0003] There is a large demand for remote switching applications in the Internet of Things (IoT). To ensure the normal operation of equipment, normally open or normally closed switches or jog buttons are often used with intermediate relays connected in a specific electrical circuit to achieve the characteristic of the target equipment maintaining a certain action for a long time. For example, the existing technology disclosed in Chinese Patent Publication No. "CN209606800U" is a remote switch control terminal with holding function based on LoRa communication technology, which includes a microcontroller, a reset button, a relay, a configurable signal acquisition port, a TTL serial port, an LED indicator, a 220V battery module and a LoRa communication module. The microcontroller is connected to the reset button, the relay, the configurable signal acquisition port, the TTL serial port, the LED indicator and the LoRa communication module respectively.

[0004] The prior art, Chinese Patent Publication No. CN108010762B, discloses a remote switch with electromagnetic control. It includes a fixing member, a toggle member connected in sequence, a swing plate with contact points, and metal terminals with contact points. The swing plate is arranged vertically and can swing horizontally with the movement of the toggle member; contact points are respectively arranged on both sides of the swing plate; and a support member is included to support the swing plate.

[0005] In actual operation, there is no anti-accidental touch structure around the control button. In the event of accidental touch or unintended operation, the lack of anti-accidental touch measures can easily cause the control button to be pressed and transmit control signals, resulting in unnecessary erroneous operation, making it less practical. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where the control buttons lack an anti-accidental touch structure, and to propose a LORA-based remote switch.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a LoRa-based remote switch, including a switch base and an internal control unit. The control unit is connected to the LoRa controller body via a wireless module. A control button is provided on the end face of the switch base, and a protective cover is provided around the control button. An anti-accidental touch component is also provided around the switch base, and the anti-accidental touch component is connected to the protective cover.

[0009] The protective cover is rotatably connected to the switch base via a rotating rod, and the protective cover and the rotating rod are detachably connected.

[0010] Furthermore, the anti-accidental touch component includes a first connecting part, which is disposed on the side of the switch base. A groove is formed by an inward recess on the side of the first connecting part. The groove communicates upward with the first connecting part and is slidably connected to an unlocking element inside by a compression spring.

[0011] Furthermore, a second connecting part is integrally formed on the side of the protective cover. The bottom of the second connecting part has a first claw. The top of the unlocking member is provided with a second claw. The opposite sides of the first claw and the second claw are provided with guide slopes, and they are engaged with each other through the guide slopes.

[0012] Furthermore, a protective member is rotatably connected to the periphery of the first connecting part. The protective member has a U-shaped structure and slides against the top of the second connecting part.

[0013] Furthermore, the protective cover is connected to the rotating rod via a pair of elastic parts on the side, and the rotating rod is rotatably connected to the switch base via fixed seats at both ends and torsion springs.

[0014] Furthermore, the elastic part has a through hole at the midpoint, and the bottom of the elastic part connects to the through hole to form a deformation groove. Both sides of the end of the rotating rod are provided with limiting grooves. The rotating rod is engaged in the through hole through the deformation grooves, and the limiting grooves are inserted into and locked with the through hole.

[0015] The present invention proposes a remote switch based on LoRa, which has the following advantages: The present invention can fix the protective cover through the anti-accidental touch component. By setting the protective cover, the control button can be shielded and protected, which can prevent unnecessary erroneous operation caused by the force transmitted to the control button in the event of accidental touch or accidental operation. Furthermore, the protective cover can be unlocked by pressing the unlocking part, and the protective cover automatically flips under the action of the rotating rod and torsion spring for easy operation. Moreover, when the protective cover is damaged or needs to be replaced after long-term use, the protective cover can be quickly replaced by separating the elastic part from the rotating rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A remote switch based on LoRa includes a switch base 1 and a control unit inside it. The control unit is connected to the LoRa controller body via a wireless module. A control button 2 is provided on the end face of the switch base 1, and a protective cover 3 is provided around the control button 2. An anti-accidental touch component 4 is also provided around the switch base 1, and the anti-accidental touch component 4 is connected to the protective cover 3.

[0024] The protective cover 3 is rotatably connected to the switch base 1 via a rotating rod 5, and the protective cover 3 and the rotating rod 5 are detachably connected.

[0025] It should be added that, in some embodiments, the control unit in the LORA remote switch also includes a communication module, a holding relay, a signal acquisition port, and a power supply module. The relay converts the control commands received by the LoRa communication module into long-term control actions on the target device. In addition, the configurable signal acquisition port can synchronously collect the operating parameters of the current target device according to the user-defined configuration, and transmit them to the corresponding gateway for data integration via the LoRa communication module using LoRa signals. Of course, the control button 2 is electrically connected to the control unit.

[0026] Furthermore, the anti-accidental touch component 4 includes a first connecting part 41, which is disposed on the side of the switch base 1. A groove 411 is formed by an inward recess on the side of the first connecting part 41. The groove 411 is connected upward to the first connecting part 41 and is slidably connected to an unlocking member 43 inside by a compression spring 42.

[0027] Furthermore, a second connecting part 44 is integrally formed on the side of the protective cover 3. The bottom of the second connecting part 44 has a first claw 441. The top of the unlocking member 43 is provided with a second claw 431. The opposite sides of the first claw 441 and the second claw 431 are provided with guide slopes, and they are engaged with each other through the guide slopes.

[0028] It is worth mentioning that, such as Figure 4 As shown, one side of the unlocking member 43 extends to the periphery of the first connecting part 41. Pressing the unlocking member 43 drives the second claw 431 to disengage from the first claw 441. The protective cover 3 flips under the action of the rotating rod 5 and the torsion spring, so that the control button 2 can be operated. The compression spring 42 is used to reset the unlocking member 43.

[0029] The first claw 441 and the second claw 431 have the same structure, both being L-shaped, and are arranged opposite to each other. The advantage of setting the guide slope is to reduce the friction generated when the pair of claws are engaged.

[0030] More specifically, a protective member 45 is rotatably connected to the periphery of the first connecting part 41. The protective member 45 has a U-shaped structure and is pressed against the top of the second connecting part 44 by sliding against it.

[0031] Specifically, the protective part 45 is pressed against the top of the second connecting part 44 by rotating, so that the first connecting part 41 and the second connecting part 44 will not separate even if the unlocking part 43 is accidentally touched.

[0032] The structure of the anti-accidental touch component 4 in this embodiment can refer to the opening and closing structure of the thermos cup lid in the prior art.

[0033] In general, the protective cover 3 is connected to the rotating rod 5 via a pair of elastic parts 31 on the side, and the rotating rod 5 is rotatably connected to the switch base 1 via fixed seats at both ends and torsion springs.

[0034] Specifically, the protective cover 3 is kept open from the switch base 1 under the action of the rotating rod 5 and the torsion spring. The elastic part 31 is preferably made of a material with deformation ability such as rubber or plastic.

[0035] Finally, the elastic part 31 has a through hole 311 at the midpoint, and the bottom of the elastic part 31 is connected to the through hole 311 to form a deformation groove 312. The rotating rod 5 has a limiting groove 51 on both sides of its end. The rotating rod 5 is engaged in the through hole 311 through the deformation groove 312. The limiting groove 51 is inserted into and locked in the through hole 311.

[0036] In specific operations, such as Figure 5 As shown, the opening diameter of the deformation groove 312 is smaller than the diameter of the rotating rod 5. The elastic part 31 uses the deformation groove 312 to engage with the rotating rod 5 by means of abutting deformation. In addition, the limiting groove 51 will also be inserted and locked with the through hole 311 to ensure that the rotating rod 5 can drive the protective cover 3 to rotate synchronously.

[0037] Working method: During operation, the first claw 441 and the second claw 431 fix the protective cover 3 by engaging, and the protective cover 3 prevents the control button 2 from being accidentally touched.

[0038] Then, press the unlocking piece 43 to cause the second claw 431 to separate from the second claw 431. The protective cover 3 flips under the action of the rotating rod 5 and the compression spring, so that the control button 2 can be operated.

[0039] Finally, the rotating rod 5 and the elastic part 31 can be directly separated by contact deformation, and the protective cover 3 can be disassembled and replaced.

[0040] 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.
