Description

Technical Field

[0001] This utility model relates to the field of button technology, and in particular to an audible and visual emergency button used in industrial automated production equipment. Background Technology

[0002] In the field of industrial automation, emergency buttons are key control components that ensure the safe operation of equipment and the safety of personnel. They are mainly used to quickly cut off the power source of equipment or trigger emergency protection mechanisms in the event of sudden failures or dangerous scenarios.

[0003] Existing emergency buttons for industrial automation mostly employ a single mechanical trigger structure, typically consisting of a housing, a switch housed within the housing, and a button connected to the switch. Status indication is provided solely through the button's own pressed state (e.g., raised / depressed) or a simple indicator light, with emergency stop achieved by pressing the button. However, when the button is in an active state (e.g., emergency protection has been triggered or is ready to be triggered), it is difficult for non-operators to quickly and accurately confirm its actual working status. They cannot visually determine whether the button has effectively triggered the emergency function, and it is easy to confuse "normal standby" with "fault lockout" states, leading to misjudgment.

[0004] Therefore, the limitations of this status indication directly lead to safety defects; misjudgment may cause operators to miss the opportunity for emergency response, or to accidentally deactivate emergency protection, thereby inducing secondary equipment failures and production accidents, posing a significant threat to personnel safety and stable equipment operation in industrial sites.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] 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.

[0035] Please see Figures 1-6 As shown, this embodiment of the utility model provides an audible and visual emergency button 100. The audible and visual emergency button 100 includes a housing 1 with a receiving space 13, a button assembly 2 installed in the housing 1, a light-emitting assembly 3 fixed in the housing 1, and a buzzer 4 fixed to and electrically connected to the light-emitting assembly 3. The light-emitting assembly 3 is used to emit light, and the buzzer 4 is used to emit sound. The receiving space 13 of the housing 1 is used to install the light-emitting assembly 3 and the buzzer 4.

[0036] The housing 1 includes a base 11 and an upper cover 12 covering the base 11. The base 11 and the upper cover 12 are detachably and fixedly connected and together form the receiving space 13.

[0037] The light-emitting component 3 is located within the receiving space 13, and is sleeved on the button assembly 2 and fixed to the upper cover 12. The base 11 is used to support and fix the upper cover 12, and the upper cover 12 is used to install and fix the light-emitting component 3, so that the light-emitting component 3 is installed well.

[0038] The upper cover 12 includes an upper cover body 121 that is fixed to the base 11, a through hole 122 formed therethrough through the upper cover body 121, and a light-transmitting part 123 made of light-transmitting material that protrudes from the side of the upper cover body 121 away from the base 11; the button assembly 2 is inserted into the through hole 122, the light-emitting assembly 3 is fixed to the side of the upper cover body 121 near the base 11, and the light-emitting side of the light-emitting assembly 3 is arranged opposite to the light-transmitting part 123.

[0039] The button assembly 2 is fixed to the side of the upper cover 12 near the base 11. The button assembly 2 includes a button 21 and a switch 22 installed in the receiving space 13. The button 21 is inserted into the through hole 122 and exposed on the upper cover 12. The button 21 is installed in the receiving space 13, and one end of the button 21 in the receiving space 13 abuts against the switch 22 to trigger the switch 22. By pressing the button 21, the switch 22 can be turned on or off, thereby realizing the on / off control of the switch 22. The button 21 has a good control effect. At the same time, when the button 21 is pressed, the switch 22 is triggered, causing the light-emitting component 3 to automatically light up and the buzzer 4 to sound. By setting the button assembly 2 in the through hole 122 of the upper cover body 121, emergency stop control can be achieved by pressing the button assembly 2, which has high safety. The light emitted by the light-emitting component 3 is transmitted to the external environment through the light-transmitting part 123, and the sound is emitted by the buzzer 4, thereby realizing an audio-visual warning. This allows for a more effective and accurate judgment of the current status. The button component 2 is pressed based on the light and sound, preventing misjudgment and ensuring high safety.

[0040] Specifically, the height of the portion of button 21 exposed above the top cover 12 is less than the height of the light-transmitting portion 123. This reduces the obstruction of the light-transmitting portion 123 by button 21, allowing it to be visible from 360 degrees for a better warning effect. Furthermore, the light-transmitting portion 123 serves as a protective structure for button 21; when pressed abnormally, it is blocked by the light-transmitting portion 123, effectively preventing the button 21 from being pressed incorrectly, thus improving reliability.

[0041] Optionally, the through hole 122 of the upper cover body 121 can also be an elastic structure, so that the button 21 can return to its original position after being pressed, and the button 21 has a good pressing experience.

[0042] In this embodiment, the light-emitting component 3 includes a circular circuit board 31 and a plurality of light sources 32 fixed to the side of the circuit board 31 away from the base 11. The buzzer 4 is fixed to the side of the circuit board 31 near the base 11, and the plurality of light sources 32 and the buzzer 4 are electrically connected to the circuit board 31 respectively; the circuit board 31 is sleeved on the button assembly 2 and fixedly connected to the upper cover 12.

[0043] In this embodiment, the plurality of light sources 32 are arranged in a circular array along the circumference of the circuit board 31, and the plurality of light sources 32 are positioned opposite to the light-transmitting part 123.

[0044] Optionally, the light source 32 can be an LED (Light-Emitting Diode), a halogen warning light, or an emergency fluorescent light, etc.

[0045] The LED lights can intuitively distinguish the working status of button 21, avoiding misjudgment; at the same time, they can adapt to harsh environments such as dust, humidity, and high-frequency vibration in industrial workshops, ensuring stable operation of the warning function.

[0046] Using halogen LEDs as the light source, it has high luminous intensity and strong penetrating power for warning colors such as red / yellow light, making it clearly identifiable even in strong light, dusty, or foggy environments. It also has good vibration resistance, making it suitable for high-frequency vibration scenarios such as industrial equipment and workshop passages. It is often paired with strobe or flashing modes to enhance the warning effect.

[0047] It uses fluorescent tubes for illumination, featuring low power consumption and uniform light emission. Some models also have built-in batteries that can automatically turn on after a power outage. It is suitable as an auxiliary warning light source in industrial sites, such as near power distribution cabinets and emergency exits, to continuously provide warning guidance when the main power supply fails, preventing personnel from accidentally touching dangerous areas.

[0048] In this embodiment, the buzzer 4 can be an Autonics B7VA-24 or an Omron PKB24A120, etc. The Autonics B7VA-24 is an active electromagnetic buzzer 4, compatible with 24VDC industrial standard voltage, supporting 8 switchable warning sounds (including continuous ringing, intermittent popping, etc.), and highly matched with the trigger-alarm logic of the emergency stop button 21. It has an IP65 protection rating, resisting dust and splashes in industrial environments, and its compact size facilitates integration into the button 21 housing 1, making it suitable for emergency stop buttons 21 in automated production lines, machine tools, and other equipment. The Omron PKB24A120 is a miniature active buzzer 4, compatible with 24V voltage, and its small size makes it suitable for compact emergency stop buttons 21 in space-constrained environments. It can still emit sound stably under equipment vibration and supports synchronous control with LED lights, achieving simultaneous sound and light warnings and improving status recognition efficiency.

[0049] In this embodiment, the light-transmitting portion 123 includes a light-transmitting portion body 1231 that protrudes from the upper cover body 121 in a direction away from the base 11, and a light-guiding groove 1232 formed by the recess of the light-transmitting portion body 1231 from the side near the base 11 in a direction away from the base 11; the light source 32 is positioned directly opposite the light-guiding groove 1232. By positioning the light source 32 directly opposite the light-guiding groove 1232, the light source 32 can be better transmitted, resulting in a better light guiding effect. Simultaneously, it can reduce the number of light sources 32 required, saving costs.

[0050] In this embodiment, the audible and visual emergency button 100 further includes multiple support pillars 5 and multiple first screws 7. The multiple support pillars 5 are fixed to the upper cover body 121 at intervals, and each support pillar 5 has a first threaded hole 51. The circuit board 31 is screwed and fixed to the first threaded hole 51 after passing through the circuit board 31 with the first screw 7. The connection between the first screw 7 and the first threaded hole 51 makes it convenient for the support pillars 5 to fix the circuit board 31 to the upper cover body 121, and also facilitates disassembly and assembly. In addition, fixing the circuit board 31 with the support pillars 5 can separate the circuit board 31 from the upper cover body 121, further improving the heat dissipation performance of the circuit board 31, thereby increasing the service life of the circuit board 31.

[0051] Optionally, circuit board 31 is a PCBA (Printed Circuit Board Assembly), which assembles electronic components (such as chips, resistors, capacitors, diodes, connectors, etc.) through soldering processes to form a circuit module with complete electrical functions. It is the core circuit carrier of electronic equipment. The PCBA board is the core control unit; it integrates the identification of whether button 21 is pressed, the control of the LED warning light's on / off state and flashing mode, and the control of the buzzer 4's sound frequency and duration. It also carries a power management module (adapting to industrial field voltage to ensure stable power supply), which can quickly respond to button 21 operation and synchronously trigger the sound and light warning function. It is the key hardware foundation for realizing status visualization and warning linkage.

[0052] Optionally, the multiple first screws 7 are three in number and are evenly distributed on the circuit board 31.

[0053] In this embodiment, the sound and light emergency button 100 also includes a power source, which is a battery or an external power source, used to power the light-emitting component 3 and the buzzer 4, etc.

[0054] In this embodiment, the audible and visual emergency button 100 further includes multiple second screws 8, and the base 11 and the upper cover 12 are fixedly connected by the multiple second screws 8. This facilitates the disassembly or assembly of the base 11 and the upper cover 12.

[0055] In this embodiment, the housing 1 has a rectangular structure; four second screws 8 are respectively located at the four corners of the housing 1; the second screws 8 pass through the upper cover 12 and the base 11, thus forming a screwed connection between the upper cover 12 and the base 11. By providing four second screws 8 at the four corners of the housing 1, the fixing effect between the upper cover 12 and the base 11 can be improved. At the same time, the fixed connection by the second screws 8 facilitates the assembly and disassembly of the upper cover 12 and the base 11.

[0056] In this embodiment, the audible and visual emergency button 100 further includes multiple plugs 6, which are respectively covered and fixed to the ends of the multiple second screws 8 away from the base 11. The plugs 6 can seal the positions of the second screws 8, improving the overall sealing performance of the audible and visual emergency button 100.

[0057] The upper cover 12 also includes a mounting groove 125 formed by recessing the upper cover body 121 from the side away from the base 11 toward the base 11, a second threaded hole 126 and a guide hole 127 formed through the mounting groove 125 and spaced apart from each other, and a slot 128 formed by recessing the inner wall of the guide hole 127.

[0058] The plug 6 includes a plug body 61, a guide post 62 protruding from the plug body 61 towards the base 11, and a buckle 63 extending radially outward from the outer periphery of the guide post 62. The second screw 8 passes through the second threaded hole 126 and is fixedly connected to the base 11. The plug body 61 is disposed in the mounting groove 125 and forms a seal, the guide post 62 is inserted into the guide hole 127, and the buckle 63 is engaged with the slot 128 to fix the plug 6 to the upper cover 12. The buckle 63 of the plug 6 is engaged and fixed in the slot 128, facilitating the assembly and disassembly of the plug 6 and the upper cover 12.

[0059] In this embodiment, the upper cover 12 further includes a sealing groove 124 formed by the recess of the upper cover body 121 from the side near the base 11 toward the direction away from the base 11; the base 11 includes a bottom wall 111 and a side wall 112 formed by bending and extending the periphery of the bottom wall 111 toward the upper cover 12. The audible and visual emergency button 100 also includes a sealing ring 9, which is disposed in the sealing groove 124, and the side wall 112 presses the sealing ring 9 into the sealing groove 124 to form a seal. By placing the sealing ring 9 between the base 11 and the upper cover 12, the sealing performance of the housing 1 can be improved, achieving the effect of waterproofing and dustproofing.

[0060] Optionally, the sealing ring 9 is made of silicone. Silicone material possesses high elasticity and resistance to permanent compression deformation. When assembling the base 11 and the top cover 12, it can compensate for minor dimensional deviations caused by processing errors, and buffer the compressive stress during assembly, preventing cracks in the rigid housing 1 due to rigid contact, resulting in a good sealing effect. The silicone sealing ring 9, with its excellent elastic deformation capability, can tightly fill the assembly gap between the base 11 and the top cover 12, forming a closed-loop sealing structure, preventing impurities such as moisture, dust, and oil from entering the button 21; preventing short circuits, corrosion, or functional failures in core components such as the internal PCBA board, LED beads, and buzzer 4 due to foreign object intrusion, ensuring stable audible and visual warning functions.

[0061] In this embodiment, the light-transmitting portion 123 is made of quartz glass or ordinary glass. Preferably, the light-transmitting portion 123 is made of quartz glass.

[0062] Ordinary glass has a visible light transmittance of about 90%-92%, but it contains impurities such as sodium and calcium. After long-term use or when it is affected by industrial dust and oil, it is prone to light transmittance attenuation (such as surface corrosion and fogging), which may lead to a decrease in the brightness of the warning light and a slight deviation in color, affecting visual recognition at a distance or in noisy industrial sites.

[0063] Made of high-purity silica (SiO), the quartz glass has a visible light transmittance of 93%-95% and stronger light uniformity, with no light scattering caused by impurities. It is also resistant to oil and dust, and its light transmittance decreases very little with long-term use, ensuring clear and stable transmission of warning lights (especially high-frequency warning colors). It is suitable for scenarios with high requirements for warning visibility (such as large workshops and industrial environments with multiple devices interfering with each other).

[0064] Compared with related technologies, in the embodiments of this utility model, a light-emitting component and a buzzer are installed in the housing's receiving space. The buzzer is electrically connected to the light-emitting component, which emits light, and the buzzer emits sound. The housing includes a base and a top cover on the base, which are detachably and fixedly connected. The top cover and the base together form the receiving space. A button assembly is fixed to the side of the top cover near the base, and the light-emitting component is sleeved on the button assembly and fixed to the top cover. The top cover includes a top cover body fixed to the base, a through hole formed therethrough in the top cover body, and a part of the top cover body. A light-transmitting section made of light-transmitting material protrudes from the side of the body away from the base; a button assembly is fixedly installed in the through hole, and the button assembly includes a button and a switch installed in the receiving space; the button is inserted into the fixed through hole and exposed outside the top cover, and the end of the button located in the receiving space abuts against the switch to trigger the switch; a light-emitting component is fixed to the side of the top cover body near the base, and the light-emitting side of the light-emitting component is opposite to the light-transmitting section; by emitting light through the light-emitting component and emitting sound through the buzzer, more effective and correct judgments can be made, preventing misjudgments and ensuring high safety.
