Description

Technical Field

[0001] The utility model belongs to the technical field of alarms, and specifically provides a portable rechargeable alarm. Background Art

[0002] This lightweight, versatile alarm is designed to provide visual and auditory warnings for quickly deploying safety zones and enhancing safety at maintenance and construction sites. Placed at the forefront of the construction zone, it provides comprehensive safety protection through sound, light, electricity, and electric flagging, ensuring safe production. Placed at the forefront of the construction zone, it provides comprehensive safety protection through sound, light, electricity, and electric flagging, replacing manual flagging at the front of the construction zone and improving safety at work. The sound, light, and electricity signals effectively warn passing vehicles to give way, ensuring safe production.

[0003] During the process of road construction or road accident handling, the construction or accident handling unit needs to set up an alarm in front of the relevant control area. The alarm transmits restricted traffic alarm information to social vehicles that are about to enter the control area through display screens and speakers to prevent them from mistakenly entering the control area; thereby facilitating the safe operation of construction personnel and avoiding accidental injuries to external social vehicles and personnel in the control area.

[0004] The inventors learned that in order to effectively display alarm information on a display screen, the display screen and even the entire alarm device must be relatively large, making it inconvenient to quickly transport between storage and transportation warehouses and different control areas, and its portability is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a portable charging alarm that can at least solve one of the above technical problems.

[0006] To address the above-mentioned problems in the prior art, one or more embodiments of the present invention provide a portable charging alarm, comprising a first body and a second body, wherein one end of the first body and one end of the second body are rotatably connected via a first rotating shaft, and the first body and the second body can rotate relative to each other to form a folded state and an unfolded state; in the folded state, the angle between the first body and the second body is less than 10 degrees, and in the unfolded state, the angle between the first body and the second body is greater than 170 degrees;

[0007] The first body and the second body each have a mounting surface. In the folded state, the mounting surfaces of the first body and the second body are arranged relative to each other; a first display screen is attached to the mounting surface, and a second display screen is rotatably mounted on the edge of the mounting surface of the first body and the second body, respectively. The second display screen is rotatably connected to the first body or the second body via a second rotating shaft; the first rotating shaft and the second rotating shaft are perpendicular to each other; a rechargeable battery is disposed in the inner cavity of the first body and / or the second body; a speaker is disposed on the surface of the first body and / or the second body; and a controller is disposed in the inner cavity of the first body or the second body, and the controller is used to control the first display screen, the second display screen, and the speaker.

[0008] Beneficial effects of one or more of the above technical solutions:

[0009] Compared to the integrated display screen in the prior art, the present invention divides the alarm into a first body and a second body that can rotate relative to each other to a folded state and an unfolded state. The mounting surfaces of the first and second bodies are attached with a first display screen, and the first and second bodies are each rotatably mounted with a second display screen at the edge of the mounting surface. In this arrangement, after the first and second bodies are rotated to a folded state and the first display screen is rotated to mate with the second display screen, the size of the display screens along the plane direction can be greatly reduced; that is, the alarm of this embodiment can stack four display screens (two first display screens and two second display screens) in the thickness direction of the alarm by rotating the first and second bodies and the second display screen, thereby reducing the size of the entire alarm along the length and width directions, making the alarm easy to carry.

[0010] That is to say, this solution divides a single larger display screen into two first display screens and two second display screens, which can improve the portability of the entire charging alarm during transportation while meeting the display area. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-Figure 4 As shown, a portable charging alarm provided in this embodiment includes a first body 2 and a second body 20, one end of the first body 2 and one end of the second body 20 are rotatably connected by a first rotating shaft 6, and the two can rotate relative to each other to a folded state and an unfolded state; in the folded state, the angle between the first body 2 and the second body 20 is less than 10 degrees, and in the unfolded state, the angle between the first body 2 and the second body 20 is greater than 170 degrees.

[0021] Specifically, the first body 2 has a first bracket 7, the second body 20 is provided with a second bracket 5, the first bracket 7 and the second bracket 5 are provided with mounting holes, the mounting holes of the first bracket 7 and the second bracket 5 are connected to each other and the above-mentioned first rotating shaft 6 is passed through the mounting holes.

[0022] Specifically, the outer contours of the first and second bodies 2, 20 are generally rectangular. Each of the first and second bodies 2, 20 includes a detachably connected first and second outer shells 21, 22, which are joined to form the inner cavities of the first and second bodies 2, 20. More specifically, a sealing strip is provided at the joint between the first and second outer shells 21, 22 to seal the inner cavities of the first and second bodies 2, 20.

[0023] The first body 2 and the second body 20 respectively have mounting surfaces. In the folded state, the mounting surfaces of the first body 2 and the second body 20 are arranged opposite to each other; a first display screen 12 is attached to the mounting surfaces respectively, and the first body 2 and the second body 20 respectively have a second display screen 4 rotatably mounted on the edges of the mounting surfaces. The second display screen 4 is rotatably connected to the first body 2 or the second body 20 through a second rotating shaft 11; the first rotating shaft 6 and the second rotating shaft 11 are perpendicular to each other; a rechargeable battery is arranged in the inner cavity of the first body 2 and / or the second body 20; a speaker 8 is arranged on the surface of the first body 2 and / or the second body 20; a controller is arranged in the inner cavity of the first body 2 or the second body 20, and the controller is used to control the first display screen 12, the second display screen 4 and the speaker 8.

[0024] Specifically, the first body 2 and the second body 20 are respectively provided with a mounting seat 10 , and both ends of the second rotating shaft 11 are rotatably connected to the mounting seat 10 .

[0025] Specifically, the mounting surface is preferably a flat surface so as to fit the first display screen 12. In some other embodiments, the mounting surface may also be a slightly curved surface.

[0026] In this embodiment, the surface of the first display screen 12 is in contact with the mounting surface, and the two can be bonded together by an adhesive. In other embodiments, the first display screen 12 can be fixed to the mounting surface by connecting members such as bolts.

[0027] Specifically, the mounting surface is rectangular and has four sides, wherein two adjacent sides are a first side and a second side. The first rotating shaft 6 is mounted on the first side, and the second rotating shaft 11 is mounted on the second side.

[0028] In this embodiment, a first torsion spring is installed at the first rotating shaft 6, and the first torsion spring is used to provide a driving force for the first body 2 and the second body 20 to rotate to the unfolded state; a first magnetic adsorption component 3 and a second magnetic adsorption component 30 are respectively provided on the two mounting surfaces; in the folded state, the first magnetic adsorption component 3 and the second magnetic adsorption component 30 are attracted to each other.

[0029] Specifically, the first torsion spring is sleeved on the outside of the first rotating shaft 6. The first torsion spring has two force-bearing ends, one of which is abutted against the first body 2, and the other is abutted against the second body 20. When the first body 2 and the second body 20 are rotated toward the folded state, the first torsion spring is compressed and accumulates elastic potential energy; when the first body 2 and the second body 20 are rotated toward the unfolded state, the first torsion spring is prevented from loosening and releases elastic potential energy. In addition, the first magnetic adsorption member 3 and the second magnetic adsorption member 30 here can both be magnets; in some other embodiments, one of the first magnetic adsorption member 3 and the second magnetic adsorption member 30 is a magnet, and the other is a ferromagnetic metal.

[0030] In this embodiment, a second torsion spring is installed at the second rotating shaft 11 , and the second torsion spring is used to provide a driving force for the second display screen 4 to rotate in a direction away from the installation surface.

[0031] Specifically, the second torsion spring is sleeved around the exterior of the second rotating shaft 11. It also has two force-bearing ends: one end abuts the second display screen 4, and the other abuts the adjacent first body 2 or second body 20. When the second display screen 4 is rotated to an angle of less than 10 degrees relative to the mounting surface, the second torsion spring is compressed and accumulates elastic potential energy. When the second display screen 4 is rotated to an angle of more than 170 degrees relative to the mounting surface, the second torsion spring releases this elastic potential energy.

[0032] In this embodiment, the first body 2 and the second body 20 further respectively have an outer surface facing away from the installation surface, and the solar cell panels 1 are installed on the outer surfaces.

[0033] Specifically, the solar cell panel 1 is connected to the rechargeable battery via an electrical conductor.

[0034] In this embodiment, a vibration sensor is provided on the first body 2 and / or the second body 20, and the vibration sensor is in signal communication with the controller. The vibration sensor can adopt an existing design, and the signal connection between the vibration sensor and the controller can also be connected by those skilled in the art according to existing designs.

[0035] In this embodiment, the first body 2 or the second body 20 is provided with a satellite positioning module and an Internet of Things communication module; the Internet of Things communication module can obtain the location information of the satellite positioning module and send the location information to the remote terminal.

[0036] Specifically, the controller can adopt an ARM processor or a single chip microcomputer, which can be configured by those skilled in the art.

[0037] In this embodiment, the mounting surface has a groove for receiving the first display screen 12. More specifically, the first display screen 12 is flush with the mounting surface. This means that the first display screen 12 does not protrude from the mounting surface, thereby preventing the second display screen 4 from interfering with the first display screen 12 during rotation.

[0038] This embodiment further includes a detachable triangular bracket (not shown), the upper end of which is detachably fixed to the lower portion of the first body 2 and / or the second body 20. Specifically, the upper end of the triangular bracket has a screw, and the alarm has a screw hole 9 that matches the screw, and the two are connected by threads.

[0039] Working principle: When using this device, the user applies a pulling force to the first body 2 and the second body 20, so that the first magnetic adsorption part 3 and the second magnetic adsorption part 30 are released from the state of magnetic adsorption. Then the first body 2 and the second body 20 are rotated to the unfolded state under the elastic force of the first torsion spring. At this time, the second display screen 4 is freed from the restraints of the first body 2 and the second body 20, and the second display screen 4 is unfolded to an angle greater than 170 degrees with the installation surface under the action of the second torsion spring. At this time, the two first display screens 12 and the two second display screens 4 are roughly in the same display plane, and the controller controls the first display screen 12 and the second display screen 4 to display related content.

[0040] When the device needs to be transported, the user applies external force to rotate the second display screen 4 to an angle less than 10 degrees with the mounting surface. Then, the user applies further external force to rotate the first and second bodies 20 to an angle less than 10 degrees, bringing the first and second magnetic elements 3, 30 into contact and mutually adsorbing. The magnetic forces of the first and second magnetic elements 3, 30 overcome the elastic forces of the first and second torsion springs. While the alarm's thickness increases, its length and width are significantly reduced, making it easier to carry and transport.
