Description

Technical Field

[0001] The invention relates to the technical field of aisle indicator lights, and in particular to a four-sided sensing structure and an aisle indicator light based on the four-sided sensing structure. Background Art

[0002] In factories and warehouses, forklift transportation and manual handling coexist, especially in cross-sections where goods are stacked, where it is easy for people and forklifts to share the same aisle, or for two forklifts to run in parallel in the same aisle. If the forklift driver fails to notice such a situation in time, or the vision is blocked by the stacked goods, the risk of accidents will increase.

[0003] The current technical countermeasures are mainly to install warning devices on the forklift body, such as forklift indicator lights, to warn people and vehicles in front of the forklift to take evasive measures through light signals. However, this solution has limitations in warehouses and factory intersections where there are dense personnel and limited space. Due to the closed environment and many obstacles, especially when people or vehicles are in another channel that intersects with the forklift channel, it is often difficult to directly observe the dynamics of the forklift, so the hidden danger of accidents still remains.

[0004] In view of the above situation, we provide a four-sided sensing structure and an aisle indicator light based on the four-sided sensing structure to solve the above problem. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a four-sided sensing structure and an aisle indicator light based on the four-sided sensing structure, which forms an all-round visual warning through the first warning light source arranged around the sheet metal shell and the passive infrared sensors of the rectangular array of equal height at four points on the top. In addition, a second warning light source and a buzzer device are added at the bottom of the sheet metal shell, which can instantly trigger the dual sound and light warning, effectively preventing the occurrence of collision accidents, especially for heavy mobile equipment such as forklifts, significantly reducing the risk of collision.

[0006] In order to achieve the above-mentioned purpose, the four-sided sensing structure adopted by the present invention includes: a sheet metal shell, a passive infrared sensor, a first warning light source and a control panel, wherein the sheet metal shell is surrounded by the first warning light source, the first warning light source is installed at the installation openings on the four sides of the sheet metal shell and a part of the first warning light source penetrates into the interior of the sheet metal shell, the number of the passive infrared sensors is four, and they extend upward along the top surface of the sheet metal shell to form a four-point rectangular array of equal height, the sensing surface of the passive infrared sensor and the irradiation surface of the first warning light source are located in the same plane, and a fixed control panel is also provided inside the sheet metal shell, the control panel is connected to the passive infrared sensor via Bluetooth, and the control panel is electrically connected to the first warning light source;

[0007] A second warning light source is also provided at the bottom of the sheet metal shell. Part of the second warning light source extends into the interior of the sheet metal shell. The second warning light source is electrically connected to the control board.

[0008] The above structure includes a sheet metal shell, a passive infrared sensor, a first warning light source and a control panel. By arranging the first warning light source around the sheet metal shell, and matching it with four passive sensors and a second warning light source and a buzzer at the bottom of the sheet metal shell, an all-round visual warning is formed.

[0009] As a further optimization of the above scheme, the interior of the sheet metal shell is a accommodating space, and a detachable supporting frame is provided on the top of the accommodating space. The control panel is located at the center of the supporting frame, and the control panel is fixed by quick-release clamps located at the four corners of the supporting frame. There are four quick-release clamps, and a four-point rectangular array is formed with the top surface of the control panel as a horizontal plane and equal height. The quick-release clamp includes a slide rail located on the supporting frame, and a fixing hole for the upper part of the clamping part to enter is opened at the lower part of the slide rail, and a connecting hole for the fixing part to slide into is formed at the upper part of the slide rail. The fixing part and the control panel are a matching structure, and installation is The plate is located on the opposite side of the above-mentioned clamping piece, and the upper part of the mounting plate has a bent lock hook, and the upper part of the lock hook extends upward to form a limiting part that limits the edge of the control plate, the upper part of the clamping piece has a vertical through hole for fixing the lock hook, the lower part of the mounting plate has a clamping hole, and the lower part of the clamping piece has a plug-in part that passes through the clamping hole and is clamped and fixed, the clamping piece and the mounting plate form a limiting hole for the upper plate body of the support frame to pass through, the plug-in part is inclined, there are two fixing pieces and the two fixing pieces slide into the connecting hole in series, and the fixing piece has a C-shaped cross-section for the control board to enter.

[0010] The above structure is equipped with a bolt-free disassembly and assembly structure in the accommodation space, thereby avoiding destructive operations on the threads of the control panel during the installation process. At the same time, the assembly process does not require specific tools, making the assembly process simpler and more efficient. In addition, the quick-release clamp not only stabilizes the control panel, but also cleverly realizes the hollow installation design of the support frame, ensuring that the bottom of the control panel remains hollow, which is beneficial to the heat dissipation of the control panel and facilitates the layout and installation of the bottom cables.

[0011] As a further optimization of the above scheme, a locking block is provided on the outer surface of the mounting plate, and a locking hole is formed on the upper surface of the locking block for the lower part of the passive infrared sensor to penetrate, and a fastening ring corresponding to the outer circumference of the support frame is formed between the support frame and the top plate of the accommodating space, and the fastening ring has an opening, one end of the opening is a fixed part, and the end of the fastening ring away from the fixed part forms a free part, the fixed part and the fastening part are arranged relatively along the opening, and four fastening grooves are sequentially provided along the circumferential direction of the fastening ring, and the fastening grooves and the locking block are a matching structure, and an adjusting member is provided at the opening, and the adjusting member is a bolt and is rotatably installed at the opening, and the adjusting member releases external force to the opening according to the rotation direction to make the opening widen or narrow, and the fastening groove narrows as the opening narrows.

[0012] The above structure incorporates an adjustable fastening ring mechanism, which relies on a rotating adjustment piece to achieve flexible adjustment of the opening size. As the opening gradually narrows, the fastening ring shrinks inward. At the same time, the fastening groove on the fastening ring gradually engages with the locking block. Since the passive infrared sensor has been firmly installed in the locking block, the fastening operation of the fastening groove not only completes the firm fixation of the entire quick-release fixture structure, but also simultaneously achieves a secure locking of the passive infrared sensor. This design abandons traditional direct locking methods such as bolts and screws. On the one hand, it simplifies the disassembly and assembly process and reduces the difficulty of operation; on the other hand, by implementing a double-layer locking strategy, it ensures the firm fixation of the two core components of the control panel and the passive infrared sensor, thereby improving the stability and safety of the overall structure.

[0013] The aisle indicator light based on the four-sided sensing structure applies the four-sided sensing structure as described in any of the above solutions.

[0014] The four-sided sensing structure of the present invention and the aisle indicator light based on the four-sided sensing structure have the following beneficial effects:

[0015] 1. The four-sided sensing structure of the present invention and the aisle indicator light based on the four-sided sensing structure include a sheet metal shell, a passive infrared sensor, a first warning light source and a control panel. The first warning light source is arranged around the sheet metal shell, matched with four passive sensors and a second warning light source and a buzzer at the bottom of the sheet metal shell, so as to form an all-round visual warning. In addition, a second warning light source and a buzzer device are added at the bottom of the sheet metal shell, which can instantly trigger a dual sound and light warning, effectively preventing the occurrence of collision accidents, especially for heavy mobile equipment such as forklifts, and significantly reducing the risk of collision.

The four-sided sensing structure of the present invention and the aisle indicator light based on the four-sided sensing structure are configured with a bolt-free disassembly and assembly structure in the accommodation space, thereby avoiding destructive operations on the threads of the control panel during installation. At the same time, the assembly process does not require specific tools, making the assembly process simpler and more efficient. In addition, while stabilizing the control panel, the quick-release clamp cleverly realizes the hollow installation design of the support frame, ensuring that the bottom of the control panel remains hollow, which is beneficial to the heat dissipation of the control panel and also facilitates the layout and installation of the bottom cables.

[0017] 3. The four-sided sensing structure of the present invention and the aisle indicator light based on the four-sided sensing structure, the above structure incorporates an adjustable fastening ring mechanism, relying on a rotating adjustment piece to achieve flexible adjustment of the opening size. As the opening gradually narrows, the fastening ring performs an inward contraction movement. At the same time, the fastening groove on the fastening ring gradually engages with the locking block. Since the passive infrared sensor has been firmly installed in the locking block, the fastening operation of the fastening groove not only completes the firm fixation of the entire quick-release clamp structure, but also simultaneously achieves a secure locking of the passive infrared sensor. This design abandons traditional direct locking methods such as bolts and screws. On the one hand, it simplifies the disassembly and assembly process and reduces the difficulty of operation; on the other hand, by implementing a double-layer locking strategy, it ensures the firm fixation of the two core components of the control panel and the passive infrared sensor, thereby improving the stability and safety of the overall structure.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0030] It should be noted that when an element is referred to as being "disposed on, provided with" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] Please refer to the instruction manual Figure 1-9The present invention provides a first embodiment of a four-sided sensing structure, which mainly includes a sheet metal housing 1, a passive infrared sensor 3, a first warning light source 2, a control panel 4 and other key components. The sheet metal housing 1 is surrounded by the first warning light source 2, which is installed in the installation openings 11 preset on the four sides of the sheet metal housing 1, and part of the structure extends into the housing. There are four passive infrared sensors 3 in total, and the four passive infrared sensors 3 are arranged vertically upward along the top surface of the sheet metal housing 1, forming a four-point rectangular array of equal height.

[0033] It should be noted that the sensing surface of the passive infrared sensor 3 and the irradiation surface of the first warning light source 2 are maintained on the same plane, thereby ensuring the coordination of the sensing and warning functions.

[0034] A control panel 4 is also fixedly installed inside the sheet metal housing 1. The control panel 4 is wirelessly connected to the passive infrared sensor 3 via Bluetooth, and is electrically connected to the first warning light source 2, thereby realizing information transmission and control. In addition, a second warning light source 5 and a buzzer 6 are also added to the bottom of the sheet metal housing 1. The second warning light source 5 partially extends into the interior of the housing and is electrically connected to the control panel 4, thereby further enhancing the warning effect.

[0035] The above structure works as follows:

[0036] like Figure 1 As shown, taking the R direction as an example, after the passive infrared sensor 3 in the R direction detects the operation of the forklift, the first warning light source 2 in the R direction and the -R direction corresponding to the R direction all flash, the second warning light source 5 at the bottom flashes, and the buzzer 6 at the bottom sounds an alarm.

[0037] After the passive infrared sensors 3 in all directions have all detected the operation of the forklift, the first warning light sources 2 in all directions will all flash and emit light, the second warning light source 5 at the bottom will flash and emit light, and the buzzer 6 at the bottom will sound an alarm.

[0038] In summary, the first embodiment integrates core components such as a sheet metal housing 1, a passive infrared sensor 3, a first warning light source 2, and a control panel 4. It also constructs an all-round, multi-level visual and auditory warning system by arranging warning light sources around and at the bottom of the housing, combining four passive infrared sensors 3, and a buzzer 6 that may be equipped.

[0039] Please refer to the instruction manual Figure 1-9The present invention provides a second embodiment of a four-sided sensing structure. On the basis of the four-sided sensing structure in the first embodiment, the internal structure of the sheet metal housing 1 is improved to make the internal structure of the sheet metal housing 1 more compact. At the same time, the use of bolts inside the sheet metal housing 1 is reduced, which is convenient for workers to install, improves the installation efficiency of the four-sided sensing structure, saves installation time for workers, and reduces the use of bolt structures, which is convenient for workers to operate, significantly improving the simplicity and efficiency of the assembly process. The specific improvements of this embodiment are as follows:

[0040] The accommodating space is arranged inside the sheet metal shell 1, and a support frame 7 is installed on the top of the accommodating space, which is designed for disassembly and connection. The control board 4 is placed at the center of the support frame 7 and is fixed by four quick-release clamps 8. The quick-release clamps 8 are based on the top surface of the control board 4 and are arranged at equal heights into a four-point rectangular array to ensure that the control board 4 is stable and balanced.

[0041] The above-mentioned quick-release clamps 8 are all composed of a slide rail 81 located on the support frame 7. The lower part of the slide rail 81 is designed with a fixing hole 811 for the upper part of the clamping member 82 to easily enter; and the upper part of the slide rail 81 is provided with a connecting hole 812 for the sliding entry of the fixing member 83. The fixing member 83 and the control panel 4 are designed to cooperate to ensure a stable installation. The mounting plate 84 is located on the opposite side of the clamping member 82, and a bent locking hook 841 is provided on its upper part. The locking hook 841 extends upward to form a limiting part 842 on the edge of the control panel 4, effectively preventing the control panel 4 from moving. The upper part of the clamping member 82 is provided with a vertical through hole 821 for the locking hook 841 to fix, thereby realizing double locking. The lower part of the mounting plate 84 is designed with a clamping hole 843, which cooperates with the plug-in part 822 at the lower part of the clamping member 82 to form a stable clamping fixation.

[0042] It should be noted that the clamping member 82 and the mounting plate 84 together form a limiting hole 85 for the upper plate of the support frame 7 to pass through, and the plug-in portion 822 is inclined to facilitate installation and disassembly.

[0043] Furthermore, in the present embodiment, the central portion of the support frame 7 is hollowed out to facilitate heat dissipation of the control board 4 and facilitate connection of cables through the hollow portion.

[0044] In this embodiment, there are two fixing members 83, and the two fixing members 83 are connected in series and slide into the connection hole 812 to form a double fixation. The fixing member 83 has a C-shaped cross section, which perfectly matches the control board 4, ensuring the stability of the installation and facilitating disassembly.

[0045] The above structure realizes a bolt-free disassembly and assembly design in the accommodation space, effectively avoiding the potential risk of thread damage to the control panel 4 during the installation process. The entire assembly process does not need to rely on specific tools, which greatly simplifies the assembly steps and accelerates the work efficiency. Especially for large-scale production environments, given that the assembly of the structure involves manual assembly of internal precision parts, it is impossible to fully realize mechanized automatic installation. In this situation, the traditional bolt structure needs to frequently use tools such as screwdrivers to operate in a limited space, which requires strict professional skills of the operators and is inefficient. In contrast, the assembled structure adopted by the present invention, with multiple clamping mechanisms, realizes convenient assembly without tools, which is particularly suitable for the efficient installation requirements in small spaces. In addition, while ensuring the stability of the control panel 4, the quick-install clamp 8 also cleverly achieves the hollow installation of the support frame 7, so that the bottom of the control panel 4 remains transparent. This design not only promotes the effective heat dissipation of the control panel 4, but also facilitates the neat layout and convenient installation of the bottom cables, fully reflecting the high efficiency and practical value of the design.

[0046] Based on the above structure, without considering the cost, further improvements can be made to the disassembly and assembly design. The specific improvements are as follows:

[0047] A locking block 844 is provided on the outer surface of the mounting plate 84, and a locking hole is formed on the upper surface of the locking block 844 for the lower part of the passive infrared sensor 3 to penetrate. A fastening ring 9 corresponding to the outer circumference of the support frame 7 is formed between the support frame 7 and the top plate of the accommodating space, and the fastening ring 9 has an opening 91, one end of the opening 91 is a fixed portion 92, and the end of the fastening ring 9 away from the fixed portion 92 forms a free portion 93, the fixed portion 92 and the fastening portion are arranged relatively along the opening 91, and four fastening grooves 94 are sequentially provided along the circumferential direction of the fastening ring 9, and the fastening grooves 94 are a matching structure with the locking block 844, and an adjusting member 95 is provided at the opening 91, and the adjusting member 95 is a bolt and is rotatably installed at the opening 91, and the adjusting member 95 releases external force to the opening 91 according to the rotation direction, so that the opening 91 can be widened or narrowed, and the fastening groove 94 narrows as the opening 91 narrows.

[0048] This structure cleverly integrates the adjustable fastening ring 9 mechanism, and uses the rotating adjustment member 95 to flexibly control the size of the opening 91. As the opening 91 gradually narrows, the fastening ring 9 also shrinks inward. During this process, the fastening groove 94 on the fastening ring 9 gradually engages tightly with the locking block 844. Since the passive infrared sensor 3 has been firmly installed in the locking block 844, the fastening effect of the fastening groove 94 not only stabilizes the entire quick-release clamp 8 structure, but also effectively locks the passive infrared sensor 3. At the same time, while achieving the fixing work of the passive infrared sensor and the quick-release clamp 8, it has the ability to protect against external impact. If an external impact enters the interior of the accommodating space, the fastening ring 9 that is subjected to the external impact will lock inward and further fix the quick-release clamp 8, so as to effectively protect the quick-release clamp 8 and the control board 4 inside the quick-release clamp 8.

[0049] The design of the second embodiment abandons the traditional direct locking method of bolts and screws, which not only simplifies the disassembly and assembly procedures and reduces the complexity of operation, but also ensures the firm fixation of the two key components, the control board 4 and the passive infrared sensor 3, through the double-layer locking mechanism, significantly improving the stability and safety of the overall structure.
