Abstract
Description
Technical Field
[0001] This utility model relates to the field of signage technology, and in particular to safety exit signage devices. Background Technology
[0002] Emergency exit signs are typically affixed to walls or hung above safety exits. They can display escape routes on one or both sides, showing running directions and arrows to guide the way.
[0003] In the relevant technical solutions, due to limitations in power supply and signal cable placement, safety signs can only be affixed to the walls on the left and right sides of the escape route. This means that the display surface of the safety signs may be parallel to the escape route, and combined with the smoke inside the building, it is even more likely that escapers will overlook the indicated escape direction, failing to provide timely guidance and causing panic.
[0004] In particular, if the safety exit signs placed at intersections are not quickly identified by those escaping, it can easily lead to incorrect choices of escape direction. Utility Model Content
[0005] This utility model provides a safety exit sign device that can solve at least one of the above-mentioned technical problems.
[0006] To address the aforementioned technical problems, one or more embodiments of this utility model provide a safety exit sign device, including a first display panel. The middle portion of the first display panel is rotatably connected to one end of a second display panel, and a torsion spring is provided at the connection point. The spring force is configured to drive the second display panel from its position against the middle portion of the first display panel to a position perpendicular to the first display panel. A display surface is formed on the side of the first display panel facing the second display panel, and both sides of the second display panel are also display surfaces. An electromagnet assembly is provided between the side of the second display panel that is attached to the first display panel and the first display panel. The on / off state of the electromagnet assembly is controlled by a controller capable of detecting external power.
[0007] The beneficial effects of one or more of the above technical solutions are as follows:
[0008] In this solution, the traditional single flat safety exit sign is replaced with a first display panel and a second display panel that can rotate and connect to each other. One end of the second display panel is rotatably connected to the middle of the first display panel. A torsion spring is installed on the connection structure between the first and second display panels, and an electromagnet assembly is also provided between them. When not in use, the second and first display panels can be attached to the walls on both sides of the passage to reduce space occupation.
[0009] When emergency exit signs are needed, the electromagnet assembly can be de-energized, causing the torsion spring to quickly rotate the second display panel to a position perpendicular to the first display panel. In other words, the first and second display panels can display emergency exit information at different angles, greatly reducing the chance of users overlooking emergency exit signs.

Detailed Implementation
[0014] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0015] See Figures 1-3 This embodiment provides a safety exit sign device, including a first display panel 1. The middle part of the first display panel 1 is rotatably connected to one end of a second display panel 2, and a torsion spring 3 is provided at the connection structure between the two. The elastic force provided by the torsion spring 3 is set to drive the second display panel 2 from being attached to the middle part of the first display panel 1 to moving perpendicular to the first display panel 1. The side of the first display panel 1 facing the second display panel 2 forms a display surface, and both sides of the second display panel 2 are display surfaces. An electromagnet assembly is provided between the side of the second display panel 2 that is attached to the first display panel 1 and the first display panel 1. The on / off state of the electromagnet assembly is controlled by a controller, which can detect external power.
[0016] Specifically, both the first display panel 1 and the second display panel 2 are rectangular display panels. In use, the side of the first display panel 1 that does not display information is fixed to the side of the wall of the safety passage by means of adhesive or bolts. The side of the second display panel 2 that displays information is located on the side of the second display panel 2 facing the center of the safety passage.
[0017] Specifically, the electromagnet assembly includes a first electromagnet 4 fixed to the first display panel 1 and a second electromagnet 5 fixed to the second display panel 2. When energized, the first electromagnet 4 and the second electromagnet 5 attract each other, making the magnetic force greater than the elastic force provided by the torsion spring 3, thus keeping the second display panel 2 in a fixed, attached state to the first display panel 1. When de-energized, there is no magnetic force between the first electromagnet 4 and the second electromagnet 5, and the elastic force provided by the torsion spring 3 drives the second display panel 2 to rotate relative to the first display panel 1. Consequently, most of the second display panel 2 detaches from the first display panel 1, and the second display panel 2 extends towards the center of the escape route, with the two display panels perpendicular to each other. In other words, when the electromagnet assembly is de-energized, one of the first display panel 1 and the second display panel 2 always faces the escape direction of the escapee, providing a more clearly visible information indication.
[0018] In this embodiment, the display surface of the first display panel 1 has a first display area 103 and a second display area 102 arranged along the length direction, and the first display area 103 and the second display area 102 are separated by a bracket. One end of the second display panel 2 is rotatably connected to the bracket via a rotating shaft. A torsion spring 3 is sleeved on the outside of the rotating shaft, and one of the force-bearing ends of the torsion spring 3 abuts against the first display panel 1, and the other force-bearing end abuts against the second display panel 2.
[0019] Specifically, the pivot here is the connection structure described above. In one specific structural form, the pivot is fixed to the second display panel 2 and rotatably connected to the bracket. In other embodiments, the pivot is fixed to the bracket and rotatably connected to the second display panel 2.
[0020] In this embodiment, the surface of the first display panel 1 has a groove 101 for accommodating the second display panel 2, and the support is provided on the bottom surface of the groove 101. The surface of the first display panel 1 without the groove 101 forms a first display area 103, and the bottom surface of the groove 101 forms a second display area 102.
[0021] In this configuration, when the second display panel 2 is embedded in the groove 101, the second display panel 2 is flush with the outermost surface of the second display panel 2 to avoid collisions when it protrudes from the first display panel.
[0022] In this embodiment, the first display panel 1 is a single-sided LED panel, and the second display panel 2 is a double-sided LED panel. Both the first display panel 1 and the second display panel 2 include a metal frame 6 and a display panel body embedded in the metal frame 6.
[0023] Specifically, this embodiment uses a high-brightness LED panel, displaying a green "running human figure + arrow" logo. The metal frame 6 is made of fire-resistant alloy and has built-in heat dissipation channels.
[0024] In this embodiment, the surface of the display panel body is covered with a tempered glass layer.
[0025] Specifically, the tempered glass layer here is high-temperature resistant tempered glass.
[0026] In this embodiment, a main power supply and a battery are also included. The main power supply and the battery supply power to the controller, the electromagnet assembly, the first display panel 1, and the second display panel 2, respectively. Specifically, the battery here should provide at least 90 minutes of emergency power.
[0027] This embodiment also includes a smoke sensor and a wireless communication module. The smoke sensor is connected to the controller via a signal. The controller can also communicate with the building's internal fire protection system via the wireless communication module.
[0028] Specifically, this embodiment also includes a fireproof optical cable, which, combined with the wireless communication module, forms a dual communication guarantee.
[0029] In this embodiment, a buzzer alarm is also included, which is connected to the controller via a signal.
[0030] When the smoke detector is triggered, the smoke sensor detects the current smoke concentration. If the smoke concentration is low, a level one alarm is triggered, the LED panel brightness increases and begins to flash. If the smoke concentration is high, a level two alarm is triggered, the LED panel display brightness increases to its maximum, and the buzzer is activated.
[0031] This embodiment also includes a temperature sensor that can be connected to the controller signal. The ambient temperature is displayed when the ambient temperature is >60°C.
[0032] Working principle: When not in use, the first display panel 1 can be attached to the walls on both sides of the passage, and the second display panel 2 is embedded in the groove 101 on the surface of the first display panel 1 to reduce space occupation.
[0033] When emergency exit signs are required, the electromagnet assembly is de-energized, causing the torsion spring 3 to quickly rotate the second display panel 2 to a position perpendicular to the first display panel 1. The first display panel 1 and the second display panel 2 can display emergency exit information at different angles, greatly preventing users from overlooking emergency exit signs.
[0034] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.
[0035] Any aspects of this utility model not described in detail are known to those skilled in the art.
