Description

Technical Field

[0001] This application relates to the field of road sign technology, and specifically discloses a mobile road vehicle control guidance sign. Background Technology

[0002] In scenarios such as road construction, temporary traffic control, accident handling, or special events, it is usually necessary to set up directional signs on relevant road sections to guide passing vehicles, set speed limits, or provide safety warnings. Traditional directional signs have a single function and are usually static signs with fixed patterns or text.

[0003] With the development of intelligent transportation technology, modern directional signs have integrated multiple functional modules to improve guidance effectiveness and control capabilities. For example, LED displays are added to provide dynamic video or text instructions; speaker systems are installed to broadcast audio guidance information; and surveillance cameras are integrated to monitor road traffic conditions in real time. This integration of functions greatly enhances the intelligence and information technology level of directional signs.

[0004] However, the increase in functional modules has directly led to a more complex overall structure for directional signs, with more internal circuitry and supporting components, resulting in a significant increase in their overall size and weight. Currently, most of these multifunctional directional signs on the market still adopt a portable design concept for easy temporary deployment and do not possess self-propelled capabilities. In practical applications, staff need to manually carry them to the target controlled area. For heavier equipment, multiple people are usually required to complete the carrying and placement.

[0005] This manual handling method has the following obvious drawbacks: First, it greatly increases the workload and labor burden of on-site staff, especially when the deployment location needs to be changed frequently, resulting in low efficiency; second, the bulky equipment also affects the response speed of deployment and dismantling, making it difficult to meet the rapidly changing traffic control needs.

[0006] Therefore, existing directional signs rely on manual handling, which results in problems such as high labor intensity and slow deployment speed. In view of this, this utility model provides a mobile road vehicle control directional sign to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to solve the problems of traditional directional signs relying on manual handling, which leads to high labor intensity and slow deployment speed.

[0008] To achieve the above objectives, the basic solution of this utility model provides a mobile road vehicle control guidance sign, including a guidance sign body and a mobile component that can accommodate the guidance sign body and drive the guidance sign to move. The mobile component includes a frame, several casters at the bottom of the frame, and a handrail on one side of the frame. Several support rollers are rotatably connected to the frame. The sign body can move on the frame along the rotation direction of the support rollers, and a fixing mechanism that can be detachably connected between the sign body and the frame is provided.

[0009] The principle and effect of this basic scheme are as follows: Compared with existing technologies, this utility model incorporates a movable component to facilitate the transport of the directional sign body, enabling quick and efficient deployment and removal. Furthermore, support rollers support the directional sign body, facilitating its placement on or removal from the movable component. A fixing mechanism secures or disassembles the directional sign body to the vehicle frame, ensuring overall fixation or removal of the directional sign body and the movable component. This effectively prevents damage to the directional sign body from uneven or bumpy road surfaces, expanding the application range of this utility model and effectively solving the problems of traditional directional signs relying on manual handling, resulting in high labor intensity and slow deployment speed.

[0010] Furthermore, the vehicle frame is provided with a mounting frame, and the support rollers are rotatably connected within the mounting frame, with the tops of each support roller extending beyond the top surface of the mounting frame. This facilitates the installation of each support roller, thereby providing convenience for placing or removing the directional sign body from the vehicle frame.

[0011] Furthermore, the support roller includes a connecting shaft disposed between the two sides of the mounting frame and a rolling sleeve sleeved around the circumference of the connecting shaft and rolling along the connecting shaft. This improves the support strength of the support roller itself, and at the same time improves the strength of the connection structure between the support roller and the mounting frame and the vehicle frame, thereby providing overall support for the directional sign.

[0012] Furthermore, the bottom of the sign body is provided with a base that slides along the surface of the support roller, and both ends of the base have smooth curved surfaces. This facilitates the sliding of the sign on the surface of the support roller, and further facilitates the placement of the sign body onto or removal from the vehicle frame.

[0013] Furthermore, the width of the base is less than the length of the support roller to prevent the directional sign from detaching from the support roller.

[0014] Furthermore, the sign body includes a housing, a PCB board inside the housing, a display screen, a speaker, and a camera outside the housing, as well as a portable power source to power the PCB board, display screen, speaker, and camera. This is to meet current requirements for video guidance, audio guidance, and video surveillance on signage.

[0015] Furthermore, the fixing mechanism includes fixing plates symmetrically arranged on the vehicle frame and located at both ends of the support roller, fixing lugs symmetrically arranged on both sides of the housing, and fixing bolts that can connect and fix the fixing lugs to the fixing plates. This facilitates the connection or disassembly of the directional sign body to the vehicle frame.

[0016] Furthermore, the fixing plate is evenly provided with a plurality of threaded holes adapted to the fixing bolts, and the fixing lug is provided with a through groove parallel to the axial direction of the support roller. The fixing bolts pass through the through grooves and connect to the threaded holes. This reduces the accuracy requirements for the installation position of the directional sign and facilitates the connection or disassembly of the directional sign body to the vehicle frame.

[0017] Furthermore, a connecting bracket is provided between the fixing lugs on the same side of the housing, and the connecting bracket is connected to the side wall of the housing. This improves the structural strength of the connection between the sign body and the vehicle frame.

[0018] Furthermore, the housing is symmetrically inclined with inserts on both sides, and indicator flags are detachably connected to the inserts to enhance the functionality of the directional sign body. Attached Figure Description

Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] The reference numerals in the accompanying drawings include: frame 1, handlebar 2, caster wheel 3, mounting frame 4, support roller 5, fixing plate 6, threaded hole 7, housing 8, base 9, fixing lug 10, fixing bolt 11, display screen 12, camera 13, speaker 14, plug 15, battery box 16, handle 17, counterweight seat 18, and armrest 19.

[0023] A mobile road vehicle control guidance sign, implementing, for example Figures 1 to 3 As shown: It includes the sign body, a moving component that moves the sign body, and a fixing mechanism for fixing the sign body.

[0024] The sign body includes a housing 8. The front of the housing 8 is equipped with a display screen 12, a speaker 14 and a camera 13. The two sides of the housing 8 are respectively equipped with inserts 15, and the inserts 15 hold directional flags by plugging them in. The back of the housing 8 is equipped with a power bank through a battery box 16. The two sides of the back of the housing 8 are also equipped with handles 17. A PCB board is installed inside the housing 8 and is connected to the display screen 12, the speaker 14 and the camera 13. The power bank supplies power to the PCB board, the display screen 12, the speaker 14 and the camera 13.

[0025] The mobile assembly includes a frame 1, several casters 3 at the bottom of the frame 1, and a handrail 2 on one side of the frame 1. A mounting frame 4 is fixedly installed in the middle of the frame 1 by welding. The mounting frame 4 contains several support rollers 5 arranged along the travel direction of the frame 1. Specifically, each support roller 5 includes a connecting shaft between the two sides of the mounting frame 4 and a rolling sleeve fitted around the circumference of the connecting shaft and rolling along the connecting shaft. This improves the support strength of the support roller 5 itself and the connection strength between the support roller 5 and the mounting frame 4 and the frame 1, thus providing overall support for the directional sign. The tops of the support rollers 5 extend beyond the top surface of the mounting frame 4 to prevent collisions between the directional sign and the mounting frame 4.

[0026] The bottom of the housing 8 is provided with a base 9 that slides along the surface of the support roller 5. Both ends of the base 9 are smooth curved surfaces, and the bottom back of the housing 8 is also provided with a counterweight 18 to prevent the housing 8 from tilting, so that the guidance sign can slide on the surface of the support roller 5, thereby facilitating the placement of the guidance sign on the frame 1 or removal from the frame 1. The width of the base 9 is less than the length of the support roller 5 to prevent the guidance sign from detaching from the support roller 5.

[0027] The fixing mechanism includes fixing plates 6 symmetrically arranged on the frame 1 and fixing lugs 10 respectively arranged on the side walls of the housing 8 or the counterweight 18. The fixing plates are evenly provided with a plurality of threaded holes 7, and the fixing lugs 10 are provided with through grooves parallel to the axial direction of the support roller 5. The fixing mechanism also includes fixing bolts 11 passing through the through grooves and fitting into the threaded holes 7. This facilitates the connection or disassembly of the sign body to the frame 1, and the through grooves reduce the accuracy requirements for the installation position of the sign, providing convenience for the connection or disassembly of the sign body to the frame 1.

[0028] A connecting frame 19 is also provided between the fixed lugs 10 located on the same side of the housing 8 or on the same side of the counterweight 18. The connecting frame 19 is fixed to the housing 8, the counterweight 18, and the fixed lugs 10 to improve the structural strength of the connection between the sign body and the frame 1.

[0029] In this embodiment, the directional sign body can be installed onto the vehicle frame 1, and the directional sign body can be transported using a moving component, allowing for quick and easy deployment and removal of the directional sign. During the installation of the directional sign body onto the vehicle frame 1, it is only necessary to tilt the directional sign body so that one end of the base 9 overlaps with the support roller 5, and then lift the directional sign body, allowing it to move along the support roller 5 and be fixed in the appropriate position. This process is not only labor-saving and convenient but also reduces wear and tear on the directional sign body as it moves on the vehicle frame 1, facilitating the overall fixing or disassembly of the directional sign body and the moving component. Furthermore, the detachable configuration of the directional sign body and the vehicle frame 1 allows for real-time installation or removal of the directional sign body as needed, effectively preventing damage from uneven or bumpy road surfaces.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
