Description

Technical Field

[0001] This invention relates to the field of pedestrian warning devices, and in particular to a two-way human body sensing retractable corner warning device. Background Technology

[0002] In densely populated places such as schools, hospitals, and office buildings, the corners of corridors and the corners of pillars and walls are prone to collisions due to the lack of cover, especially when the light is dim or people are walking quickly, often causing unnecessary injuries to pedestrians.

[0003] Common protective measures in existing technologies include installing protective foam or reflective strips at wall corners. These methods typically only provide passive protection and cannot reduce the corresponding risks at the source. Furthermore, if the equipment is installed in a dark or poorly lit location, it cannot provide timely alerts. Active alarm devices also cannot provide real-time monitoring, are cumbersome to install, and have poor effectiveness in terms of human detection and passive alarms, failing to provide accurate and effective alerts.

[0004] Therefore, there is an urgent need for a two-way retractable corner indicator that can accurately identify and effectively alert pedestrians, while being easy to install and use, in order to solve the above problems. Summary of the Invention

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A bidirectional human body sensing retractable corner indicator includes a device mounting structure and a cable rewind rack. The device mounting structure includes mounting base A and mounting base B, which are identical in structure and horizontally opposite each other. Mounting base A includes a warning light source, a battery compartment, and a position sensor. The warning light source is located outside mounting base A, and its mounting height is higher than the end face of mounting base A. The battery compartment is located to one side of the warning light source and contains a control module and a battery module for inputting control signals and supplying power to the warning light source. The position sensor is located below the warning light source and faces away from the end face of mounting base A, for identifying the position of pedestrians around the device and inputting alarm signals to the control module. The cable rewind rack is located to one side of mounting base A and contains a winding shaft and a coil spring structure for winding the power cord. Mounting base B has a cable connector on the side near the cable rewind rack for fixing the power cord connection and synchronizing the control module information of mounting base B with that of mounting base A.

[0007] As an improvement, the upper ends of mounting base A and mounting base B are equipped with mounting frames. There are two sets of mounting frames arranged opposite each other, and photovoltaic panels are mounted on their inner sides. The photovoltaic panels are detachably connected to the mounting frames by bolts. A photovoltaic terminal block is provided below the photovoltaic panels for connecting and storing the electrical energy generated by the photovoltaic panels to the battery module through lines.

[0008] As an improvement, the upper end of the warning light source is equipped with a horn. There are two horns, which are designed symmetrically with the warning light source as the center. The horns are connected to the control module through a circuit and are used to cooperate with the warning light source to provide an audible and visual alarm.

[0009] As an improvement, the upper end of the mounting base A is provided with a wireless signal transceiver module. The wireless signal transceiver module is connected to the control module through a line and is used to receive the overall control signal data of the equipment and send the operation data to the administrator terminal.

[0010] As an improvement, the line winding frame also includes a locking structure, which is adjustablely plugged into the line winding frame. The winding shaft of the line winding frame has square grooves at both ends, which are used to cooperate with the square protrusion at the lower end of the locking structure to restrict the rotation of the winding shaft. The upper end of the outer shell of the line winding frame has a limit protrusion, which is used to cooperate with the locking structure to limit the position.

[0011] As an improvement, mounting base A and mounting base B have a fixing plate on the side away from the battery compartment, and one side of the fixing plate has an adhesive area for use with double-sided tape to fix and connect to the wall.

[0012] The beneficial effects of this invention are as follows: by setting two sets of mounting base structures, bidirectional sound and light alarm reminders can be fully provided in the vertical direction, such as at corner positions or column positions. Combined with the power cord structure, it further facilitates the installation of the equipment and is suitable for different corner column installation situations.

[0013] By setting up a location sensor structure, pedestrians can be detected and identified with high precision, thereby ensuring sufficient alerts when people pass by and guaranteeing their safety.

[0014] By installing structures such as photovoltaic panels and batteries, the power demand of the device can be met, and it can maintain operation for a long time under sufficient sunlight. Attached Figure Description

[0018] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figure 1 and Figure 2 As shown, a bidirectional human body sensing retractable corner indicator includes a device mounting structure and a cable reel 10. The device mounting structure includes mounting base A1 and mounting base B2, which are identical in structure and horizontally opposite each other. Mounting base A1 includes a warning light source 4, a battery compartment 5, and a position sensor 6. The warning light source 4 is located outside the mounting base A1, and its mounting height is higher than the end face of the mounting base A1. The battery compartment 5 is located on one side of the warning light source 4 and contains a control module and a battery module for emitting light through the warning light. Source 4 inputs control signals and power supply. The position sensor 6 is located below the warning light source 4 and faces away from the end face of mounting base A1. It is used to identify the position of pedestrians around the device and input alarm signals to the control module. The cable reel 10 is located on one side of mounting base A1 and has a reel and spring structure inside for reeling in the power cable 12. The side of mounting base B2 near the cable reel 10 has a cable connector 14 for fixing the power cable 12 connection and synchronizing the control module information of mounting base B2 with that of mounting base A1. The mounting bases A1 and B2 are made of engineering plastic and have multiple sets of reinforcing ribs inside to enhance structural strength and separate corresponding installation spaces for convenient internal structure installation and positioning.

[0020] The upper ends of mounting bases A1 and B2 are equipped with mounting brackets 7. Two sets of mounting brackets 7 are arranged opposite each other, and each bracket has a photovoltaic panel 9 on its inner side. The photovoltaic panel 9 is detachably connected to the mounting bracket 7 by bolts. Below the photovoltaic panel 9 is a photovoltaic terminal block 8, used to connect and store the electrical energy generated by the photovoltaic panel 9 to the battery module via wiring. The upper end of the warning light source 4 is equipped with two horns 3, symmetrically designed around the warning light source 4. The horns 3 are connected to the control module via wiring to provide an audible and visual alarm in conjunction with the warning light source 4. An LED display screen can be installed in the battery compartment 5 to display specific text information in conjunction with the audible and visual alarm.

[0021] The upper end of the mounting base A1 is equipped with a wireless signal transceiver module 13. This module is connected to the control module via a line and is used to receive overall control signal data from the device and send operational data to the administrator terminal. The cable reel 10 also includes a locking structure 11, which is adjustablely plugged into the cable reel 10. The reel of the cable reel 10 has square grooves at both ends to cooperate with the square protrusion at the lower end of the locking structure 11 to restrict the rotation of the reel. The upper end of the outer shell of the cable reel 10 has a limit protrusion to cooperate with the locking structure 11 for position limitation. Mounting bases A1 and B2 have a fixing plate on the side away from the battery compartment 5. One side of the fixing plate has an adhesive area for fixing to the wall with double-sided tape. The power cord 12 is wrapped with a waterproof and sun-proof layer to isolate external interference and ensure normal operation of the device.

[0022] When in use, the photovoltaic panel 9 uses a monocrystalline silicon flexible solar cell and can operate under indoor artificial light. The warning light source 4 uses a red LED light group, which can illuminate within a 160° range. During installation, the operator can confirm the position at two adjacent locations, such as a wall corner or a column, peel off the double-sided adhesive on the back of mounting brackets A1 and B2, and fix them to the wall. At the same time, the operator adjusts the orientation of the photovoltaic panel 9 to ensure maximum light-receiving area. Then, the operator connects to the wireless signal transceiver module 13 via a mobile terminal to confirm the normal operation of the equipment. When an alarm is triggered, the position sensor 6 identifies the movement information of people on the corresponding side. After identifying the corresponding data, it inputs a command to the control module. Simultaneously, the sensor 6 on the other side also identifies the movement information of people and inputs a command to the control module. When pedestrians are detected on both sides, the control module inputs an activation command to the two warning light sources 4 and the speaker 3, which will generate a corresponding audible and visual alarm to alert pedestrians passing by at the corner to avoid the area. When not in use, the photovoltaic panel 9 structure continuously converts light energy into electrical energy and stores it in the battery module.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
