Furthermore, existing signs cannot be remotely controlled, cannot be automatically deployed or retracted according to actual traffic control needs, and cannot achieve coordinated control of multiple signs, making it difficult to meet the requirements of modern intelligent traffic management. Especially in situations requiring temporary lane closures, traditional signs cannot respond quickly enough and cannot automate lane closure operations. Utility Model Content

[0035] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.
[0036] refer to Figures 1-4 This application provides a sign 230 retraction device, including a housing 100 and a retraction component 200.
[0037] The housing 100 has a receiving cavity and an opening 110 communicating with the receiving cavity. The housing 100 is a structure for housing and protecting internal components, providing physical isolation and environmental protection for the internal components. The receiving cavity, as the internal space of the housing 100, can be designed in shape and size according to actual needs, such as a cuboid, a cylinder, or other regular geometric shapes. It is mainly used for installing and fixing the storage and retraction components 200. The opening 110 serves as a passage for the sign 230 to enter and exit the housing 100. Its position and size need to be adapted according to the size and movement trajectory of the sign 230, for example, it can be set at the top, side, or end of the housing 100.
[0038] The retractable component 200 is disposed within the receiving cavity. The retractable component 200 includes a drive member 210, a transmission member 220, and a sign 230. The drive member 210 is connected to the transmission member 220 and drives the transmission member 220 to reciprocate. One end of the sign 230 is connected to the transmission member 220. The drive member 210 in the retractable component 200 can be implemented in various forms, such as an electric motor, hydraulic cylinder, or pneumatic push rod, providing power to drive the transmission member 220 to complete the reciprocating motion. The transmission member 220 can be implemented using a rack and pinion mechanism, a linkage mechanism, or a slide rail and slider mechanism, transmitting the power of the drive member 210 to the sign 230 and ensuring that the sign 230 moves along a predetermined trajectory. The sign 230 is connected to the transmission member 220 by bolt fixing, snap-fit connection, or adhesive bonding.
[0039] When the driving component 210 drives the transmission component 220 to move, the transmission component 220 can drive the other end of the sign 230 to extend out of the receiving cavity through the opening 110 to display relevant information to the outside. When it is not needed to display, the sign 230 can be retracted into the receiving cavity, which can protect the sign 230 and save space.
[0040] This application, through the integrated design of the housing 100 and the retraction component 200, avoids the necessity of manual operation of the sign 230, solving the safety risks and time waste caused by personnel exposure to traffic flow in highway environments. The housing 100's accommodating cavity provides a protective space for the retraction component 200, preventing external environmental interference with the automated process, while the opening 110 ensures that the sign 230 can be completely retracted into the cavity when not in operation and stably extended when in operation. The retraction component 200 achieves mechanical transmission to replace manual operation through the connection between the drive component 210 and the transmission component 220, thereby realizing remote or automatic control of the sign 230's movement without on-site personnel intervention. This design fundamentally solves the problem of traditional sign 230 requiring manual adjustment, installation, and retrieval, meeting the practical needs of highway maintenance or clearing operations while effectively solving the safety risks and inefficiencies associated with manual adjustment, installation, and retrieval of the sign 230.
[0041] The housing 100 is equipped with a mounting base 120. The transmission component 220 includes a transmission belt 221, a first pulley 222, and a second pulley 223. Both the first pulley 222 and the second pulley 223 are rotatably mounted on the mounting base 120. The transmission belt 221 is sleeved on the first pulley 222 and the second pulley 223. The output shaft of the drive component 210 is connected to the first pulley 222 and drives the first pulley 222 to rotate. A sign 230 is connected to the transmission belt 221. The transmission belt 221 is an annular belt made of a flexible material with high wear resistance and tensile strength, such as a rubber belt or a polyurethane belt, designed to efficiently transmit power and adapt to complex motion requirements. The first pulley 222 and the second pulley 223 are components used to support and guide the transmission belt 221. They can rotate freely through a bearing structure to reduce frictional resistance and extend service life.
[0042] Specifically, a closed-loop transmission path is formed by a transmission belt 221 fitted onto the first pulley 222 and the second pulley 223, ensuring smooth power transmission from the drive component 210 to the sign 230. The sign 230, connected to the transmission belt 221, can precisely extend or retract with the linear movement of the belt 221, achieving automated control. This provides a smoother and more reliable extension / retraction function for the sign 230, while simplifying the installation process and improving the overall structural stability.
[0043] refer to Figure 4 , Figure 5 and Figure 6 The transmission component 220 also includes a support frame 224. One end of the support frame 224 is connected to the transmission belt 221, and the other end of the support frame 224 is slidably connected to the housing 100. The sign 230 is mounted on the support frame 224. By connecting one end of the support frame 224 to the transmission belt 221, power can be efficiently transmitted to the sign 230. At the same time, the other end of the support frame 224 is slidably connected to the housing 100 to form a stable linear motion path. This not only improves the accuracy and reliability of the sign 230 during automated deployment and retraction, but also overcomes the defects of inaccurate positioning or easy damage that may result from directly connecting to the transmission belt 221.
[0044] Furthermore, the housing 100 is provided with a guide rail 130, and the support frame 224 is provided with a guide post 225, which is slidably inserted into the guide rail 130. By providing the guide rail 130 on the housing 100 and the guide post 225 on the support frame 224, the support frame 224 can move precisely along the direction of the guide rail 130. The slidable insertion of the guide post 225 into the guide rail 130 not only provides a stable guiding path for the support frame 224 but also effectively prevents derailment.
[0045] A first guide wheel 140 and a second guide wheel 150 are provided on the guide rail 130 near the opening 110, and the sign 230 is located between the first guide wheel 140 and the second guide wheel 150. Specifically, the first guide wheel 140 and the second guide wheel 150 are rolling components located on the guide rail 130 near the opening 110. The rolling friction of the first guide wheel 140 and the second guide wheel 150 replaces the sliding friction, which plays a role in limiting and guiding the sign 230, ensuring that the sign 230 remains stable during the extension process.
[0046] The support frame 224 is provided with a first clamping plate 226 and a second clamping plate 227, and the transmission belt 221 is clamped between the first clamping plate 226 and the second clamping plate 227. The first clamping plate 226 and the second clamping plate 227 are two opposing clamping components used to fix the support frame 224 to the transmission belt 221. By adjusting the distance between the first clamping plate 226 and the second clamping plate 227, the device can accommodate transmission belts 221 of different thicknesses, thereby enhancing its versatility. Furthermore, the surfaces of the clamping plates can be provided with anti-slip textures or a coating that increases the coefficient of friction to further improve the stability of the connection between the support frame 224 and the transmission belt 221.
[0047] The mounting base 120 is equipped with a guide rod 121, which is parallel to the guide rail 130. The support frame 224 is equipped with a guide seat 228, which is fitted onto the guide rod 121. The parallel arrangement of the guide rod 121 and the guide rail 130 suppresses directional deviation or motion interference of the support frame 224 during sliding, thereby improving the overall operating accuracy of the device. Simultaneously, the structural design of the guide seat 228 fitted onto the guide rod 121 provides an additional guiding mechanism for the support frame 224, significantly reducing potential swaying during movement. This not only enhances the stability of the sign 230's extension and retraction but also improves the device's reliability and service life. Furthermore, the parallel arrangement of the guide rod 121 and the guide rail 130 effectively distributes the load on the support frame 224, making the sign 230 more stable and smooth when extending or retracting.
[0048] In this embodiment, multiple openings 110 and multiple retractable components 200 are provided. These retractable components 200 are arranged side-by-side within the receiving cavity, with the sign 230 in each retractable component 200 aligned with its corresponding opening 110. Specifically, the design of multiple openings 110 and multiple retractable components 200 enables independent control and coordinated operation of multiple sign 230s. The presence of multiple openings 110 ensures that each sign 230 has an independent extension channel, thereby avoiding mutual interference between sign 230s. The side-by-side arrangement of multiple retractable components 200 fully utilizes the space of the receiving cavity, ensuring a compact device structure and ease of management.
[0049] By setting up multiple retraction and extension components 200, the limitation of a single device being able to handle only a single sign 230 is not only solved, but the adaptability and operational efficiency of the device are also significantly improved, providing a more efficient and reliable device for highway maintenance or obstacle removal operations.
[0050] The sign 230 retraction device also includes a base frame 300, which is connected to the bottom of the housing 100. The base frame 300 is equipped with a solar panel 310 and a mounting bracket 320 for connection to an external structure. The solar panel 310 provides power to the drive unit 210. The base frame 300 provides additional support and a mounting foundation for the device, while the solar panel 310 is a device that generates electricity using renewable energy, reducing the device's dependence on external power sources.
[0051] In practical applications, the mounting bracket 320 is a component that facilitates the quick fixation of the device to an external structure. For example, it can be designed as a snap-on or bolt-fixed structure, with the aim of simplifying the installation process and improving deployment efficiency.
[0052] The base frame 300, through its secure connection to the bottom of the housing 100, enhances the stability and durability of the device. The solar panel 310, as the core component for energy supply, directly provides power to the drive unit 210, thus preventing device failure due to power outages. The design of the mounting bracket 320 allows for easy connection of the entire device to external structures, significantly improving the deployment flexibility of the device.
[0053] refer to Figure 7 and Figure 8 This application also provides a road system including a guardrail 400 and a sign 230 retraction and extension device. A housing 100 is connected to one side of the guardrail 400, and a drive unit 210 can extend the sign 230 to the other side of the guardrail 400 via a transmission unit 220. By integrating the guardrail 400 and the sign 230 retraction and extension device, and utilizing the drive unit 210 and transmission unit 220 to achieve the automatic extension and retraction function of the sign 230, the safety risks and low efficiency of manually placing and retrieving the sign 230 during highway maintenance or clearing operations are effectively solved, achieving the effect of supporting remote automatic control and improving overall operational efficiency.
[0054] Specifically, the sign 230 retraction device is connected to the post of the guardrail 400 via the mounting bracket 320, so that the sign 230 retraction device is located on the outside of the road. When the drive unit 210 is activated and drives the transmission unit 220 to move, the movement of the transmission unit 220 can pull the other end of the sign 230 to a position through the opening 110 and extend it to the inside of the road to remind the driver.
[0055] In this application, mechanical transmission replaces traditional manual operation, avoiding the risks associated with manually unfolding the sign 230 in a highway environment. As a result, the extension and retraction of the sign 230 is automated, significantly improving operational safety and efficiency. Furthermore, when the sign 230 needs to be retracted, the drive component 210 reverses its direction, and the transmission component 220 moves accordingly, pulling the sign 230 back into its receiving cavity. This not only meets the practical needs of highway maintenance or clearing operations but also effectively solves the safety risks and inefficiencies associated with manually adjusting, installing, and retracting the sign 230.
[0056] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0057] Furthermore, the use of terms such as "first," "second," and "a" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0058] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0059] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.
