[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0035] In some embodiments, please refer to Figures 1 to 4 This application provides an automatic alarm safety fence 100 equipped with a photovoltaic warning light, comprising: a fence unit 10 and a warning device 30. The fence unit 10 includes a fence panel 20 and a first support 11 and a second support 12 arranged side by side and spaced apart. The first support 11 and the second support 12 each have a slot 13 on their respective facing sides. The slots 13 extend along the height direction X of the fence unit 10, and both ends of the fence panel 20 are respectively inserted into the two slots 13. The warning device 30 is disposed on the fence unit 10 and includes a photovoltaic cell 32 and a warning light 33 electrically connected to the photovoltaic cell 32.

[0036] The aforementioned automatic alarm safety fence 100 has slots 13 on both sides of the first bracket 11 and the second bracket 12 facing each other. During assembly, simply inserting the two ends of the fence panel 20 into their respective slots 13 allows for stable installation between the first bracket 11 and the second bracket 12. Compared to the traditional single-piece fence structure, this fence 100 allows for quick installation and disassembly via the slots 13, offering greater convenience and greatly facilitating operation and transportation for construction personnel, thus improving construction efficiency. Since the fence unit 10 is equipped with photovoltaic cells 32 and warning lights 33, the photovoltaic cells 32, when exposed to sunlight, power the warning lights 33, effectively solving the power supply problem for outdoor operations. Furthermore, the warning lights 33 effectively alert pedestrians and vehicles, enhancing the warning effect.

[0037] It should be noted that the card slot 13 is provided on the two sides of the first bracket 11 and the second bracket 12 facing each other. This means that the slot opening 131 of the card slot 13 is located on the surface of the first bracket 11 or the second bracket 12, and the slot opening 131 of the card slot 13 on the first bracket 11 faces the second bracket 12, and the slot opening 131 of the card slot 13 on the second bracket 12 faces the first bracket 11.

[0038] To facilitate easier insertion of the fence panel 20 into the slot 13, one end of the slot 13 along the height direction X can extend to the top of the first bracket 11 or the second bracket 12. In this case, one end of the fence panel 20 can be inserted into the slot 13 starting from the top of the first bracket 11 or the second bracket 12.

[0039] Meanwhile, to prevent the fence panel 20 from detaching from the slot 131 of the slot 13, a limiting recess 133 and a limiting protrusion 21 can be provided in one of the slot wall of the slot 13 and the end of the fence panel 20, respectively. One of the limiting recess 133 and the limiting protrusion 21 extends along the height direction X. For details, please refer to [reference needed]. Figure 3 and Figure 7 When the limiting protrusion 21 is engaged in the limiting recess 133, the fence panel 20 is difficult to disengage from the slot 131 of the slot 13.

[0040] The fence panel 20 can have various shapes, such as, but not limited to, X-shaped, cuboid, or mesh. Furthermore, the number of fence panels 20 can be one or multiple. When there are multiple fence panels 20, all fence panels 20 are stacked sequentially along the height direction X between the first support 11 and the second support 12. When the fence panels 20 are respectively inserted into the slots 13 on both sides, they can be fixed by bolts, pins, or other components to further improve the stability of the structure.

[0041] It should also be noted that photovoltaic cell 32 refers to a device that generates electricity using sunlight. Using photovoltaic cell 32 can address the lack of outdoor power supply facilities, enabling self-powering; it also achieves energy conservation and consumption reduction. The source of sunlight can be sunlight or other luminous objects. To store electrical energy, an energy storage component, such as an energy storage battery, can be installed in the warning device 30 to store the daytime output of the photovoltaic cell 32 in the energy storage component to cope with environments without sunlight.

[0042] Warning light 33 refers to a device that emits light, such as an LED light, which, when in operation, uses light to warn pedestrians or motor vehicles. Warning light 33 can emit monochromatic light or multi-color light, such as flashing red and blue light.

[0043] Furthermore, the warning device 30 can be fixedly installed or movably installed on the fence unit 10. When the warning device 30 is movably installed on the fence unit 10, it can be rotated so that construction personnel can adjust the installation angle of the warning device 30, allowing the photovoltaic cell 32 to receive sunlight more effectively. The warning device 30 can be installed on at least one of the first bracket 11, the second bracket 12, and the fence panel 20. Specifically, in some embodiments, the warning device 30 is respectively installed on the top of the first bracket 11 and the second bracket 12.

[0044] Furthermore, the warning device 30 also includes a sensor and an alarm. The sensor is used to detect objects within a preset range of the fence unit 10 and feed back a sensing signal, while the alarm is used to emit an audible sound based on the sensing signal. Thus, when a pedestrian or motor vehicle is within the preset range, the sensor will detect it and emit a sensing signal. At this time, the alarm will emit an audible sound based on the sensing signal to complete the automatic alarm function.

[0045] It should be noted that the sensor and the alarm communicate through a controller. For example, when the sensor detects an object within a preset range, it sends a sensing signal to the controller. Upon receiving the sensing signal, the controller activates the alarm, emitting a sound. The controller can be, but is not limited to, a microcontroller or an electronic control unit. In some embodiments, the warning device 30 also includes a microcontroller, and both the sensor and the alarm are electrically connected to the microcontroller. Since the circuit design between the sensor, alarm, and microcontroller is not the focus of this embodiment, it will not be described in detail here; please refer to existing literature or products.

[0046] The sensor can be, but is not limited to, a photoelectric sensor, such as an infrared sensor.

[0047] Furthermore, please refer to Figure 4 and Figure 5The warning device 30 also includes a housing 31, and at least two warning lights 33. Both the photovoltaic cells 32 and the warning lights 33 are located on the outer surface of the housing 31, with all the warning lights 33 spaced apart around the periphery of the photovoltaic cells 32. The alarm is located inside the housing 31, and the housing 31 has a sound amplification hole 34. This arrangement of the photovoltaic cells 32 and warning lights 33 on the outer surface of the housing 31 improves power generation and lighting warning effects, thus enhancing product performance. Furthermore, the multiple warning lights 33 located around the periphery of the photovoltaic cells 32 facilitate electrical connection and allow light to be emitted from different angles, expanding the warning range and further improving safety.

[0048] In addition, the alarm is housed inside the housing 31, which helps to protect the alarm and prevent it from being easily corroded by nature due to exposure, thus helping to extend the service life of the equipment.

[0049] It should be noted that, to allow the photovoltaic cell 32 to better receive sunlight, the photovoltaic cell 32 can be positioned on the top of the housing 31, for example, on the side of the housing 31 facing away from the first support 11 or the second support 12. Furthermore, the number of warning lights 33 is not limited to... Figure 4 The four shown can also be others, such as, but not limited to, two, three, five or more.

[0050] In some embodiments, both the first support 11 and the second support 12 include a base 15 and a vertical rod 14. The vertical rod 14 is disposed on the base 15, and slots 13 are respectively disposed on the two opposite sides of the two vertical rods 14. Thus, by designing the first support 11 as a base 15 and a vertical rod 14, the vertical rod 14 is stably placed on the ground by the base 15, which helps to improve the structural stability of the product.

[0051] Optionally, the vertical rod 14 can be connected to the base 15 in various ways, such as, but not limited to, bolt connection, snap-fit, riveting, welding, and bonding.

[0052] Additionally, in some specific embodiments, please refer to Figure 2 The warning device 30 can be set at the end of the vertical rod 14 away from the base 15, which makes it easier to raise the warning device 30, so that the warning range can be wider and the warning effect can be improved.

[0053] Further, please refer to Figure 6Both the first support 11 and the second support 12 also include a height adjustment component 16. The height adjustment component 16 is located on the base 15 and is used to adjust the position of the base 15. Since outdoor construction is not entirely flat, for uneven ground, the height of the vertical pole 14 can be increased by the height adjustment component 16 to ensure that the fence panel 20 is installed horizontally or nearly horizontally between the first support 11 and the second support 12. This avoids the fence panel 20 structure from tilting due to uneven terrain, which could lead to protection failure.

[0054] It should be noted that the height adjustment component 16 refers to the component that can raise the height of the vertical rod 14 on the base 15. There are several ways to achieve this. For example, the height adjustment component 16 can be designed as a screw and nut structure, with the screw screwed onto the base 15 and connected to the vertical rod 14. Rotating the nut will drive the screw to rise or fall, thereby adjusting the height of the vertical rod 14. Alternatively, the adjustment component can also be designed as a jack structure, etc.

[0055] In some embodiments, please refer to Figure 1 The first bracket 11 has a first fixing part 111 on the side facing away from the slot 13, and a second fixing part 121 on the same side. In two adjacent fence units 10, the first fixing part 111 on one fence unit 10 is connected to the second fixing part 121 on the other fence unit 10. Therefore, when multiple fence units 10 are enclosed together, the first fixing part 111 on the first bracket 11 and the second fixing part 121 on the second bracket 12 can ensure a tight connection between the fence units 10.

[0056] It should be noted that there are various ways to connect the first fixing part 111 and the second fixing part 121. For example, the first fixing part 111 and the second fixing part 121 can be connected by bolts, pins, cable ties, etc. In some specific embodiments, the first fixing part 111 and the second fixing part 121 are overlapped, and then fasteners 18, such as bolts or pins, are inserted into the first fixing part 111 and the second fixing part 121 to achieve the connection between the two.

[0057] In some embodiments, please refer to Figure 7 The fence unit 10 also includes a support component 40. The support component 40 is inserted into the slot 13 and can be adjusted in position along the height direction X within the slot 13. The support component 40 supports the fence panel 20. Therefore, for sites with significant elevation differences, simply adjusting the height of the first support 11 and the second support 12 may not be sufficient for installation. To address this, the support component 40 can be installed in the slot 13, and its position can be adjusted so that the suspended end of the fence panel 20 can be stably supported by the support component 40, making the structure more stable.

[0058] It should be noted that when constructing on sites with significant elevation differences, and adjusting the heights of the first support 11 and the second support 12 is insufficient to meet installation requirements, the position of the support component 40 in the slot 13 can be adjusted. For ease of understanding, let's consider... Figure 8 Taking the first support 11, which is located at a lower elevation, one end of the fence panel 20 cannot be supported at the bottom 132 of the slot 13 and is suspended in mid-air. Over time, this will cause the fence panel 20 to tilt towards the first support 11, leading to structural instability. To address this, the height of the supporting component 40 can be increased so that the suspended end of the fence panel 20 is supported by the supporting component 40, ensuring structural balance.

[0059] Optionally, the support component 40 can be adjusted in various ways in the slot 13. For example, the support component 40 can be fixed in different positions in the slot 13 by means of pins; or, by means of a screw and slider combination structure, rotating the screw drives the slider to move up and down, thereby moving the support component 40.

[0060] Further, please refer to Figure 10 and Figure 11 The support assembly 40 includes a support body 41, a first elastic member 42, and a locking member. A locking member 43 is rotatably connected to the support body 41, and the first elastic member 42 connects the locking member 43 and the support body 41. The support body 41 passes through a slot 13. The locking member 43 extends at least partially from the opening 131 of the slot 13. The opening 131 of the slot 13 has several openings 135 spaced apart along the height direction X. The first elastic member 42 drives the locking member 43 into the openings 135. Therefore, during adjustment, the locking member 43 can be rotated out of the openings 135, unlocking the support body 41. Then, the support body 41 can be slid up and down to the desired position, releasing the locking member 43, which then engages with the corresponding opening 135 under the action of the first elastic member 42.

[0061] It should be noted that the first elastic element 42 may be, but is not limited to, a torsion spring or a spring. In some specific embodiments, the first elastic element 42 is a torsion spring, which is sleeved on the rotating shaft 44, with one end fixed to the supporting body 41 and the other end fixed to the locking element 43.

[0062] To ensure the supporting body 41 is stably locked in the slot 13, please refer to... Figure 10 There can be two locking elements 43. Mounting grooves 411 are provided on both sides of the supporting body 41, and the locking elements 43 are rotatably connected to the groove walls of the mounting grooves 411. Also, please refer to... Figure 7The slot 13 has two rows of openings 135 at its opening 131, with the two rows of openings 135 located on both sides of the supporting body 41. At this time, the two locking members 43 are respectively engaged into the corresponding openings 135 under the action of their respective first elastic members 42.

[0063] In addition, to ensure smooth sliding of the supporting body 41 within the slot 13, a first protrusion 46 and a second protrusion 47 can be provided on the supporting body 41. An adjusting recess 134 is provided on one wall of the slot 13 facing the opening 131, and a limiting recess 133 is provided on one wall of the slot 13 located on one side of the opening 131. The first protrusion 46 engages with the adjusting recess 134, and the second protrusion 47 engages with the limiting recess 133. The number of the first protrusion 46, the second protrusion 47, the adjusting recess 134, and the limiting recess 133 can be one or more, with each first protrusion 46 corresponding to one adjusting recess 134 and each second protrusion 47 corresponding to one limiting recess 133. It should be noted that the limiting recess 133 can also cooperate with the limiting protrusion on the fence panel 20.

[0064] Further, please refer to Figure 9 The fence unit 10 also includes a second elastic element 17. The second elastic element 17 is disposed on the bottom 132 of the slot 13 along the height direction X, and one end of the second elastic element 17 is used to elastically abut against the support component 40. In this way, by setting the second elastic element 17, the impact on the support component 40 can be effectively reduced, avoiding the impact of the fence panel 20 on the support component 40 during assembly, which would easily damage the support component 40 and help extend the service life of the structure.

[0065] Optionally, the second elastic element 17 may be, but is not limited to, a spring, elastic rubber, etc.

[0066] For details, please refer to Figure 9 and Figure 10 The second elastic element 17 is a spring. A first fixing post 136 can be provided on the bottom 132 of the slot 13. A second fixing post 45 is provided on the support assembly 40. The second elastic element 17 is sleeved on the first fixing post 136. The second fixing post 45 is used to insert one end of the second elastic element 17.

[0067] Additionally, in the height direction X of the fence unit 10, one end of the second elastic member 17 extends beyond at least one opening 135. If the supporting component 40 is locked in the opening 135 and compresses the second elastic member 17, after unlocking the supporting component 40, the second elastic member 17 will exert a spring force on the supporting component 40, which can assist in the disassembly of the fence panel 20, facilitating its removal. Of course, the length of the second elastic member 17 should not be too long. If it is too long, it is easy to fall out of the slot 131 of the slot 13 during compression deformation, causing the entire structure to become unstable. The specific length of the second elastic member 17 can be determined according to the actual product dimensions.

[0068] In some embodiments, please refer to Figure 12 and Figure 13 The warning device 30 is equipped with a first quick-installation structure 50, and the fence unit 10 is equipped with a second quick-installation structure 60. The first quick-installation structure 50 and the second quick-installation structure 60 are detachably connected. This greatly improves the assembly efficiency of the automatic alarm safety fence 100.

[0069] Further, please refer to Figure 12 and Figure 13 The first quick-release structure 50 includes a snap-fit ​​component 51 and a first magnetic component 52, and the second quick-release structure 60 includes a guide rail 61 and a second magnetic component 62. The snap-fit ​​component 51 has a slot 511 into which the guide rail 61 can be inserted. The slot wall of the slot 511 has a latching part 512. At least one side of the guide rail 61 has a latching groove 611 that engages with the latching part 512. The second magnetic component 62 is disposed on the guide rail 61 and magnetically engages with the first magnetic component 52. Therefore, during assembly, the snap-fit ​​component 51 is slid into the guide rail 61 through the slot 511, causing the latching part 512 to engage in the latching groove 611. When the snap-fit ​​component 51 slides to engage with the second magnetic component 62, the first magnetic component 52 and the second magnetic component 62 magnetically engage, completing the assembly of the warning device 30. Of course, during disassembly, the warning device 30 can be disassembled simply by sliding it away from the second magnetic component 62.

[0070] Both the first magnetic attractor 52 and the second magnetic attractor 62 can be permanent magnets.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
