Description

Technical Field

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

[0002] In factories and warehouses, forklift transportation and manual handling coexist, especially in intersections where goods are stacked, where personnel and forklifts often share the same aisle or two forklifts run in parallel in the same aisle. If the forklift driver fails to detect such situations in time, or the stacked goods block the view, the risk of accidents will increase significantly.

[0003] The current technical response strategy focuses on installing warning devices on the forklift body, such as forklift indicator lights, which are designed to use light signals to remind people and vehicles on the forklift's path to take evasive action. However, this solution has obvious limitations in warehouses and factory intersections with dense personnel and small spaces. Given the closed environment and dense obstacles, especially when the relevant personnel or vehicles are in another channel intersecting with the forklift channel, it is often difficult to visually observe the operating status of the forklift, so the potential for accidents still exists.

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

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a three-sided sensing structure, which is installed at a bracket where paths intersect. The sensing area of ​​each sensor is 120°, thereby achieving 360° sensing and warning without blind spots, greatly improving safety performance, and ensuring that no matter which direction a person or vehicle approaches from, it can be detected and a warning can be issued in time. At the same time, the present invention also provides an aisle indicator light based on the three-sided sensing structure to provide clear and timely guidance for the passage of people and vehicles.

[0006] In order to achieve the above-mentioned purpose, the three-sided sensing structure adopted by the present invention includes a sheet metal housing, a passive infrared sensor and an LED warning light source, wherein the sheet metal housing has two symmetrical mounting surfaces, a first side surface arranged horizontally and a second side surface arranged parallel to the first side surface, a horizontal projection of the second side surface is located on the first side surface, two third side surfaces arranged obliquely are connected between the first side surface and the second side surface, and an LED warning light source is provided on the third side surface;

A threaded section is provided at the bottom of the through hole on the second rotating member, and the connecting shaft passes through the three through holes in sequence, and the bottom end of the connecting shaft is provided with an axial thread that cooperates with the threaded section.

[0010] As a further optimization of the above scheme, the upper surface of the first rotating part is recessed downward to form a stepped hole, the stepped hole and the through hole have the same central axis, the diameter of the stepped hole is larger than the diameter of the through hole, and the end of the connecting shaft away from the shaft thread has a placement portion, and the outer end surface of the placement portion is located in the same horizontal plane as the top surface of the stepped hole.

[0011] As a further optimization of the above scheme, the lower surface of the third rotating member is recessed inward to form a notch, and the notch is fan-shaped. The upper surface of the second rotating member has a fan-shaped block and the fan-shaped block fills part of the above-mentioned notch, and the two side edges of the above-mentioned notch are located on the rotation path of the above-mentioned fan-shaped block.

[0012] As a further optimization of the above scheme, several first small circular holes are provided on the recess along the circumferential direction, and a second small circular hole corresponding to the position of the first small circular hole is provided on the fan-shaped block. A spring is fixed inside the second small circular hole, and a telescopic card rod is fixed to the outer end of the spring. The telescopic card rod passes through the second small circular hole and extends upward for a distance, and the first small circular hole and the telescopic card rod are snap-fitted.

[0013] As a further optimization of the above scheme, the mounting bracket has a horizontal plate connected to the first rotating member and the second rotating member, and the horizontal plate extends two symmetrically positioned connecting plates in the direction of the second connecting bracket. The outer ends of the connecting plates are bent inward to form bent edges. The horizontal plate and the two connecting plates form a accommodating space. The reinforcing plate is located in the above-mentioned accommodating space and separates the above-mentioned second connecting bracket and the horizontal plate.

[0016] The aisle indicator light based on the three-sided sensing structure applies the three-sided sensing structure as described in any of the above technical solutions.

[0017] The three-sided sensing structure of the present invention and the aisle indicator light based on the three-sided sensing structure have the following beneficial effects:

[0018] 1. The three-sided sensing structure of the present invention is installed at the bracket where the paths intersect. The sensing area of ​​each sensor is 120°, thereby achieving 360° sensing and warning without blind spots, greatly improving safety performance and ensuring that personnel or vehicles approaching from any direction can be detected and warned in time;

[0019] 2. The three-sided sensing structure of the present invention has two types of angle adjustment structures for passive infrared sensors in view of the differences in the needs of various factories. In the first type of design, the angle adjustment is completed with the help of a ball joint. The ball joint structure is simple in construction and economical in cost. However, it has several shortcomings in angle adjustment: the first problem is that the precision control ability is weak; secondly, it is easy to loosen during use; thirdly, it is sensitive to environmental conditions, especially in harsh factory environments such as forklift operations, and is easily affected by factors such as temperature, humidity and corrosion.

[0020] In the second type of design scheme, the present invention uses a mounting bracket to achieve angle adjustment of the passive infrared sensor. Although the assembly process of this type of mounting bracket is also simple, its cost is slightly higher than that of the first type of scheme, but the increase is limited. Among them, the mounting bracket in the second type of scheme shows higher accuracy in angle adjustment, and is particularly suitable for the three-sided sensing structure proposed in this application. Users can accurately adjust the angles of the horizontal and vertical directions online according to actual needs, and the adjustment process is more precise. In addition, this scheme is less dependent on environmental conditions.

[0021] 3. The three-sided sensing structure of the present invention adopts a rotating part splicing structure in the design of the mounting bracket, thereby forming a hinge-like rotating mechanism. Through the ingenious combination of the notch and the fan-shaped block, the passive infrared sensor is effectively limited in the horizontal direction. At the same time, the clamping design of the telescopic card rod and the second small circular hole further ensures the accuracy of the angle adjustment of the passive infrared sensor. In addition, the rotating part has no additional protrusions after splicing, which not only makes the appearance more simple and beautiful, but also effectively reduces the risk of damage by external forces.

[0022] 4. In the design of the mounting bracket for the three-sided sensing structure of the present invention, the present invention focuses on the direct connection portion with the second connecting bracket. In order to ensure the connection strength, the present application adds a reinforcing plate and a reinforcing block in the mounting bracket, thereby effectively ensuring the stability of the mounting bracket. In addition, the mounting bracket also adopts an arc-shaped limiting structure, which aims to accurately control the angle adjustment of the passive infrared sensor in the vertical direction and effectively prevent it from having excessive angle deviation. At the same time, the present invention further limits the position by using the gap formed between the reinforcing plate and the second connecting bracket, which significantly enhances the limiting effect. Regarding the precision adjustment of the position, we achieve precise control of the angle of the passive infrared sensor in the vertical direction by transforming the smooth surface and the rough surface, combining the arc-shaped groove structure, and supplemented by the plug-in function of the connector. The plug-in effect of the connector effectively realizes the precise adjustment of the angle of the passive infrared sensor in the vertical direction.

[0023] 5. The aisle indicator light based on the three-sided sensing structure of the present invention provides clear and timely guidance for the passage of people and vehicles by adopting the improved three-sided sensing structure of the present application in the aisle indicator light.

It should be understood that the scope of the embodiment of the present invention is not limited thereby, and the embodiment of the present invention includes many changes, modifications and equivalents.

[0036] 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.

[0037] Please refer to the instruction manual Figure 1 as well as Figure 2 The present invention provides a first embodiment of a three-sided sensing structure. In this embodiment, the main components of the three-sided sensing structure include a sheet metal housing 1, a passive infrared sensor, an LED warning light source 3 and a control panel. The sheet metal housing 1 is designed with a vertically symmetrical mounting surface 11, and a horizontal first side surface 12 and a second side surface 13 parallel to the vertically symmetrical mounting surface 11 are arranged between the vertically symmetrical mounting surfaces 11, and the horizontal projection of the second side surface 13 covers the first side surface 12, that is, in this embodiment, the area of ​​the first side surface 12 is larger than the area of ​​the second side surface 13, and the two are connected by two inclined third side surfaces 14, and the third side surface 14 is equipped with an LED warning light source 3.

[0038] One of the mounting surfaces 11 is provided with passive infrared sensors 2 for sensing the movements of people or objects at three angles. The three passive infrared sensors 2 correspond to two third side surfaces 14 and one first side surface 12 respectively. A control panel is provided inside the sheet metal housing 1, and the control panel is electrically connected to the passive infrared sensors 2 and the LED warning light source 3 respectively. Installed at the bracket where the paths intersect, the sensing area of ​​each sensor is 120°, thereby achieving 360° sensing and warning without blind spots, greatly improving safety performance, and ensuring that personnel or vehicles can be detected and warned in time from any direction they approach;

[0039] Among them, in this embodiment, LED warning light sources 3 are installed on the second side 13 and the third side 14. After the passive infrared sensor detects the passage of a person or a vehicle, the passive infrared sensor transmits a signal to the control panel. After receiving the signal, the control panel controls the LED warning light source 3 to emit light and sound an alarm.

[0040] In the present embodiment, the passive infrared sensor 2 is adjusted by a ball joint 51 structure. Specifically, the first connecting bracket 5 extends outward from one of the mounting surfaces 11, and the upper and lower ends of the first connecting bracket 5 are equipped with ball joints 51. A connecting rod 52 is mounted on the ball joint 51, and one end of the connecting rod 52 is connected to the passive infrared sensor 2. The ball joint 51 is used to adjust the angle of the passive infrared sensor 2. Although the ball joint 51 has a simple structure and low cost, it has some defects in practical applications. Specifically, the angle adjustment accuracy of the ball joint 51 is limited, and it is difficult to make fine adjustments; secondly, the ball joint 51 connection is prone to loosening during long-term use, affecting stability; in addition, the ball joint 51 is sensitive to environmental conditions, especially in factory environments with large changes in temperature and humidity or the presence of corrosive substances, such as forklift operation areas, and its performance and stability are easily adversely affected.

[0041] The three-sided sensing structure and the aisle indicator light based on the three-sided sensing structure provided in this embodiment have the following installation process:

[0042] First, check whether the indicator light product with the three-sided sensing structure of this embodiment has visible damage on its appearance, and whether the input cable, warning light source, and sensor are loose or damaged;

[0043] After there are no abnormal conditions, the indicator light product with the three-sided sensing structure of this embodiment is installed on the rack at the intersection through structures such as screws, bolts, washers and nuts, wherein the installation height of the product to the ground is ≥6.56ft and ≤8.2ft.

[0044] After installation, the angle of the passive infrared sensor 2 in the horizontal direction is manually adjusted through the ball joint 51 structure, but due to the influence of accuracy, this time is often longer.

[0045] Please refer to the instruction manual Figure 1-8 The present invention provides a first embodiment of a three-sided sensing structure. In this embodiment, the main components of the three-sided sensing structure include a sheet metal housing 1, a passive infrared sensor, an LED warning light source 3 and a control panel. The sheet metal housing 1 is designed with a vertically symmetrical mounting surface 11, and a horizontal first side surface 12 and a second side surface 13 parallel to the vertically symmetrical mounting surface 11 are arranged between the vertically symmetrical mounting surfaces 11, and the horizontal projection of the second side surface 13 covers the first side surface 12, that is, in this embodiment, the area of ​​the first side surface 12 is larger than the area of ​​the second side surface 13, and the two are connected by two inclined third side surfaces 14, and the third side surface 14 is equipped with an LED warning light source 3.

[0046] One of the mounting surfaces 11 is provided with passive infrared sensors 2 for sensing the movements of people or objects at three angles. The three passive infrared sensors 2 correspond to the two third side surfaces 14 and the first side surface 12 respectively. A control panel is provided inside the sheet metal housing 1, and the control panel is electrically connected to the passive infrared sensors 2 and the LED warning light source 3 respectively. Installed at the bracket where the paths intersect, the sensing area of ​​each sensor is 120°, thereby achieving 360° sensing and warning without blind spots, greatly improving safety performance, and ensuring that personnel or vehicles can be detected and warned in time from any direction they approach;

[0047] Without considering the cost, the present application further refines the angle adjustment of the passive infrared sensor 2. Specifically, in the present embodiment, the second connecting bracket 6 extends outward from one of the mounting surfaces 11, and a mounting bracket 7 is fixed thereon. The mounting bracket 7 is designed with a first rotating member 71 and a second rotating member 72 that are opposite to each other, with a gap reserved therebetween and filled by a third rotating member 73. The first rotating member 71, the second rotating member 72 and the third rotating member 73 share the same central axis. Each rotating member is provided with a vertical through hole 74, wherein the bottom of the through hole 74 of the second rotating member 72 is provided with a threaded section 721, so that the connecting shaft 75 can pass through the three through holes 74 and cooperate with them, and the bottom of the connecting shaft 75 is provided with an axis thread 751 that matches the threaded section 721.

[0048] To further optimize the structure, a stepped hole 711 is formed on the upper surface of the first rotating member 71 , which is coaxial with the through hole 74 and has a larger diameter. A placement portion 752 is provided on the connecting shaft 75 , and its outer end surface is flush with the top surface of the stepped hole 711 .

[0049] The lower surface of the third rotating member 73 is designed with a sector-shaped recess 731 , which fits with the sector-shaped block 722 on the upper surface of the second rotating member 72 , and both sides of the recess 731 are located exactly on the rotation track of the sector-shaped block 722 .

[0050] In addition, a number of first small circular holes 732 are evenly distributed around the circumference of the notch 731, and a second small circular hole 723 is provided on the fan-shaped block 722 at a corresponding position. A spring 724 is assembled inside and a telescopic clamping rod 725 is fixed. The clamping rod passes through the second small circular hole 723 and extends upward to form a clamping structure with the first small circular hole 732. This design uses rotating parts to splice, simulates the hinge rotation principle, and combines the notch 731 and the fan-shaped block 722 to achieve effective horizontal limiting of the passive infrared sensor 2. The clamping design of the telescopic clamping rod 725 and the second small circular hole 723 further enhances the accuracy of angle adjustment. At the same time, there is no additional protrusion after the rotating parts are spliced, which not only has a simple appearance, but also reduces the risk of damage.

[0051] On the basis of the above structure, the mounting bracket 7 further includes a horizontal plate 76 connected between the first rotating member 71 and the second rotating member 72, and the horizontal plate 76 extends toward the second connecting bracket 6 to form two symmetrical connecting plates 77. The outer ends of the connecting plates 77 are bent inward to form a bent edge 771. The horizontal plate 76 and the two connecting plates 77 together enclose a receiving space, and a reinforcing plate 78 is arranged in the receiving space, and the second connecting bracket 6 is separated from the horizontal plate 76 by the reinforcing plate 78, and a certain gap is retained between the second connecting bracket 6 and the reinforcing plate 78.

[0052] To further optimize the structure, the reinforcing block 781 is installed between the reinforcing plate 78 and the horizontal plate 76, and locking bolts are passed through the reinforcing plate 78, the reinforcing block 781 and the horizontal plate 76 in sequence, so that the three are firmly fixed together.

[0053] In addition, the connecting plate 77 and the reinforcing plate 78 are also designed with arc grooves 772 corresponding to the positions. The second connecting bracket 6 is provided with a plurality of fixing grooves 61 arranged in a rectangular array. Two symmetrical annular plates 8 are installed at both ends of each arc groove 772, and the annular plates 8 are connected to each other through an arc connecting piece. The plug-in component 9 is designed to be able to pass through the annular plate 8, the arc groove 772 and the fixing groove 61, and finally be clamped on one of the annular plates 8. The plug-in component 9 has a smooth surface matching the fixing groove 61, and a rough surface matching the annular groove.

[0054] Of course, in the angle adjustment structure of the connector 9, a threaded structure may be provided at the other end of the connector 9, and the position may be fixed by means of nut locking or the like.

[0055] In the design process of the mounting bracket 7, the present invention focuses on the direct connection part with the second connecting bracket 6. In order to enhance the connection strength, the present invention adds a reinforcing plate 78 and a reinforcing block 781 in the mounting bracket to ensure the stability of the mounting bracket 7. At the same time, the mounting bracket 7 also adopts an arc-shaped limiting structure, so that the angle adjustment of the passive infrared sensor 2 in the vertical direction can be accurately controlled, effectively preventing it from having an excessive angle deviation. In addition, by utilizing the gap formed between the reinforcing plate 78 and the second connecting bracket 6, the present invention also realizes a further limiting function, which significantly improves the limiting effect.

[0056] In terms of position accuracy adjustment, the present invention successfully achieves precise vertical angle adjustment of the passive infrared sensor 2 by cleverly combining the smooth surface and the rough surface, utilizing the characteristics of the arc groove 772 structure, and coordinating with the plug-in function of the plug-in connector 9. This structural design not only ensures the accuracy of angle adjustment, but also makes the entire adjustment process more convenient and efficient.

[0057] In general, the above structure realizes the angle adjustment function of the passive infrared sensor 2 by adopting the mounting bracket 7. Although the assembly process of the above mounting bracket 7 is relatively simple, its cost is slightly increased compared with the first type of solution, but the overall increase is still within an acceptable range. It is worth mentioning that the mounting bracket 7 in the second type of solution shows higher accuracy and flexibility in angle adjustment, and is particularly suitable for the three-sided sensing structure proposed in the present invention. Users can accurately adjust the angles of the sensor in the horizontal and vertical directions online according to actual needs, so as to achieve more accurate and efficient detection and warning functions. In addition, the solution is less dependent on environmental conditions and can maintain stable performance and reliability in various complex environments.

[0058] The aisle indicator light based on the three-sided sensing structure applies the three-sided sensing structure as described in any of the above technical solutions. By adopting the improved three-sided sensing structure of the present application in the aisle indicator light, clear and timely guidance is provided for the passage of people and vehicles.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
