Description

Technical Field

[0001] The utility model belongs to the technical field of traffic warning facilities, in particular to an opening and closing warning board. Background Art

[0002] Warning signs have different warning functions in different occasions. The main function of warning signs is to warn pedestrians or vehicles of dangerous matters, remind people to take corresponding safety measures as early as possible, and can also be used to remind other safety matters that must be paid attention to by staff during work. The use of warning signs can greatly reduce some casualties and accidents.

[0003] At present, the Chinese Patent Network discloses a self-luminous warning board with solar power charging [Authorization Publication Number: CN219285964U], including a device housing bracket A and a device housing bracket B for support, a control board and a battery arranged below the device housing, a cover plate covering the control board and the battery below the device housing bracket A, a lamp board and a light guide plate installed in the device housing bracket A, and a reflective paper installed behind the light guide plate. A back plate, a solar panel and an application accessory magnet for assistance are installed on the device housing bracket B. The control board and the battery are connected by wires, and the solar panel and the lamp board are connected to the control board by wires.

[0004] The above warning board has the following defects: First, the warning sign is set on the device housing bracket A, and the solar panel is set on the device housing bracket B, so that the warning board can only play a one-sided warning role. When it is necessary to warn both directions during use, two warning boards need to be set, and the practicability is poor. Second, the control board and the battery are arranged below the device housing bracket A, while the solar panel is set on the device housing bracket B. A long solar cable is required to connect the solar panel and the control board. The solar cable is exposed between the device housing bracket A and the device housing bracket B. When the device housing bracket A and the device housing bracket B are folded together, the solar cable causes a certain degree of interference, making the device housing bracket A and the device housing bracket B unable to fit completely, and there is a risk that the solar cable will be squeezed by the device housing bracket A and the device housing bracket B when they are combined, making the solar cable easily damaged. Summary of the Utility Model

[0005] The purpose of the present utility model is to address the above problems existing in the prior art and propose an opening and closing warning board. The technical problem to be solved by the present utility model is: how to solve the problems that the warning board can only give one-way warning, the two support plates cannot fit when folded, and the solar cable is easily damaged.

[0006] The purpose of the present utility model can be achieved by the following technical solutions:

[0007] An opening and closing warning board, comprising two symmetrically arranged support plates, the upper ends of the two support plates are hinged, and it is characterized in that luminous warning sign assemblies are arranged on both support plates. A solar panel is arranged at the position below the luminous warning sign assembly on the front surface of the support plate, and a controller assembly is installed at the position corresponding to the solar panel on the back surface of the support plate. A wire passing through hole is opened at the position below the luminous warning sign assembly on the support plate. The controller assembly includes a battery. The solar panel and the controller assembly are connected by a cable, and the cable is arranged through the wire passing through hole.

[0008] First, the solar panel converts light energy into electrical energy and stores it in the battery. The battery powers the luminous warning sign assembly. The controller assembly is used to control the function of the luminous warning sign assembly. After the luminous warning sign assembly is lit, it can form a luminous warning sign, which is relatively eye-catching and easy to attract the attention of pedestrians or vehicles. Luminous warning sign assemblies are arranged on both support plates of this warning board. When the two support plates are placed in an A shape, the two luminous warning sign assemblies can realize warning reminders in two directions, that is, one warning board can solve the warning reminders in two directions, which has good practicability. Second, in this structure, the solar panel is arranged on the front surface at the lower end of the support plate, and the controller assembly is arranged on the back surface at the lower end of the support plate. Then, a wire passing through hole is opened to connect the front and back surfaces of the support plate, so that the cable between the solar panel and the controller assembly is shorter. When the two support plates are combined, the cable will not be squeezed, which plays a role in protecting the cable. The cable is not easily damaged. In addition, the cable will not interfere with the combination of the two support plates, ensuring that the two support plates can be completely fitted.

[0009] In the above-mentioned opening and closing warning board, an installation groove 1 is opened at the position below the luminous warning sign assembly on the front surface of the support plate, and the solar panel is embedded in the installation groove 1. The setting of the installation groove 1 facilitates the installation and positioning of the solar panel and ensures that the solar panel is not easily displaced.

[0010] In the above-mentioned opening and closing warning board, an installation groove 2 is opened at the position corresponding to the solar panel on the back surface of the support plate, and the controller assembly is embedded in the installation groove 2. Since the controller assembly is completely located in the installation groove 2, on the one hand, it realizes the installation and positioning of the controller assembly. When the two support plates are combined, the controller assembly will not interfere with the combination of the two support plates.

[0011] In the above-mentioned opening and closing warning board, the wire passing through hole communicates with the installation groove 1 and the installation groove 2. This structure makes the length of the cable shorter on the one hand, and on the other hand, the cable realizes a concealed installation design, which further plays a role in protecting the cable. When the two support plates are combined, the cable cannot be squeezed at all.

[0012] In the above-mentioned openable warning board, the controller assembly includes a control box and a control circuit board. The control box is arranged in the second installation groove. The control circuit board and the battery are both arranged in the control box. The battery is electrically connected to the control circuit board, and the cable is electrically connected to the control circuit board. The control box integrates the battery and the control circuit board, which facilitates the installation of the battery and the control circuit board.

[0013] In the above-mentioned openable warning board, a window is opened on the support plate. A first positioning step and a second positioning step are opened on the back surface of the support plate corresponding to the window. The light-emitting warning sign assembly includes a light guide plate. Aluminum profiles are arranged on at least two opposite sides of the light guide plate. The aluminum profiles have positioning grooves, and LED light strips are arranged in the positioning grooves. The side of the light guide plate is inserted into the positioning groove, and the aluminum profiles are fixed on the support plate by screws. A light homogenizing film is arranged between the light guide plate and the second positioning step, and a layer of warning sign film is arranged on the front surface of the light homogenizing film. In this structure, the light guide plate is fixed on the support plate by aluminum profiles. When the LED light strip is lit, the light guide plate is lit. The setting of the warning sign film makes a warning sign formed on the light homogenizing film, and then the light homogenizing film is lit so that the warning sign is lit. The light homogenizing film makes the brightness of the lit warning sign softer and more uniform. The design of the window facilitates pedestrians or vehicles to observe the warning sign. In this structure, the light homogenizing film is flexible and has strong deformation performance. During installation, the light homogenizing film is loaded between the light guide plate and the second positioning step from the front direction of the support plate. The setting of the second positioning step plays a role in limiting the light homogenizing film. The installation method of the light homogenizing film is convenient for replacing the warning sign and improves the versatility of the warning board.

[0014] In the above-mentioned openable warning board, at least two linear grooves are spaced along the length direction on the first positioning step. The aluminum profile has at least two mounting holes, and the linear grooves correspond to the mounting holes one by one. When installing the aluminum profile, the screw passes through the mounting hole and is then tightened in the linear groove. The installation is convenient and the screw is firmly fixed. At the same time, the processing and manufacturing of the support plate are also convenient, and there is no need to drill threaded holes.

[0015] In the above-mentioned openable warning board, a third positioning step is opened on the back surface of the support plate corresponding to the window, and a linear groove is opened on the third positioning step. When the light-emitting warning sign assembly does not need to be installed on one of the support plates, a plate adapted to the third positioning step can be fixed on the third positioning step by screws to block the window, and the screw passes through the plate and is then tightened in the linear groove.

[0016] In the above-mentioned openable warning board, rollers are arranged at the lower ends of both support plates. During the process of dragging the warning board, the setting of the rollers makes the lower end of the warning board form rolling friction with the ground. On the one hand, it plays a role in protecting the lower end of the warning board from being easily worn. On the other hand, it also makes the position movement of the warning board faster and more convenient.

[0017] Compared with the prior art, the opening and closing warning board of the present utility model has the following advantages: Light-emitting warning sign assemblies are provided on both of the two support plates of this warning board. After the two support plates are placed in an A shape, the two light-emitting warning sign assemblies realize warning reminders in two directions, that is, one warning board solves the warning reminders in two directions, which has good practicability. Secondly, in this structure, the solar panel is arranged on the front of the lower end of the support plate, the controller assembly is arranged on the back of the lower end of the support plate, and a wire-passing through hole is opened to connect the front and back of the support plate, so that the cable between the solar panel and the controller assembly is short. When the two support plates are combined, the cable will not be squeezed, which plays a role in protecting the cable and the cable is not easily damaged. In addition, the cable will not interfere with the combination of the two support plates, ensuring that the two support plates can be completely fitted. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manners

[0031] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0032] Embodiment 1

[0033] As Figures 1 to 4 、 Figure 12As shown in the figure, this openable warning board includes two symmetrically arranged support plates 1. The upper ends of the two support plates 1 are hinged. Specifically, the two support plates 1 on both sides are hinged by a hinge shaft, and the two support plates 1 can rotate around the hinge shaft. The two support plates 1 can be placed in an A shape or rotated to a folded state; light-emitting warning sign assemblies 2 are provided on both support plates 1. A solar panel 3 is provided at the position below the light-emitting warning sign assembly 2 on the front of the support plate 1. A controller assembly 4 is installed at the position corresponding to the solar panel 3 on the back of the support plate 1. A wire passing through hole 5 is opened at the position below the light-emitting warning sign assembly 2 on the support plate 1. The controller assembly 4 includes a battery 42. The solar panel 3 is connected to the controller assembly 4 by a cable 16, and the cable 16 passes through the wire passing through hole 5. In this embodiment, an installation groove 7 is opened at the position below the light-emitting warning sign assembly 2 on the front of the support plate 1, and the solar panel 3 is embedded in the installation groove 7. An installation groove 8 is opened at the position corresponding to the solar panel 3 on the back of the support plate 1, and the controller assembly 4 is embedded in the installation groove 8. The wire passing through hole 5 communicates the installation groove 7 and the installation groove 8. First, the solar panel 3 converts light energy into electrical energy and stores it in the battery 42. The battery 42 supplies power to the light-emitting warning sign assembly 2. The controller assembly 4 is used to control the function of the light-emitting warning sign assembly 2. After the light-emitting warning sign assembly 2 is lit, it can form a luminous warning sign. This warning sign is relatively eye-catching and is easy to attract the attention of pedestrians or vehicles. Light-emitting warning sign assemblies 2 are provided on both support plates 1 of this warning board. After the two support plates 1 are placed in an A shape, the two light-emitting warning sign assemblies 2 realize warning reminders in two directions, that is, one warning board solves the warning reminders in two directions and has good practicability; in this structure, the solar panel 3 is arranged on the front of the lower end of the support plate 1, and the controller assembly 4 is arranged on the back of the lower end of the support plate 1. Then, by opening the wire passing through hole 5 to communicate the front and back of the support plate 1, the cable 16 between the solar panel 3 and the controller assembly 4 is relatively short. The cable 16 realizes a concealed installation design. When the two support plates 1 are combined, the cable 16 will not be squeezed, which plays a role in protecting the cable 16. The cable 16 is not easily damaged. In addition, the cable 16 will not interfere with the combination of the two support plates 1, ensuring that the two support plates 1 can fit completely. Although the cable 16 is not drawn in the drawings of this embodiment, the connection between the solar panel and the controller assembly by the cable 16 belongs to common knowledge.

[0034] The controller assembly 4 includes a control box 40 and a control circuit board 41. The control box 40 is arranged in the installation groove 8.
