Description

Technical Field

[0001] This utility model relates to the field of road traffic facilities technology, specifically to a windproof and tilt-proof base for an information board panel. Background Technology

[0002] Large panel structures such as outdoor information boards and traffic signs are prone to overturning under wind loads. Currently, the most common anti-overturning solution is to use a counterweight base, such as a monolithic cast-in-place concrete block or a water-filled tank. These bases provide anti-overturning moment through their enormous self-weight. Although the structure is simple, it has many inherent drawbacks: First, its wind resistance performance is fixed and passive. The stability of a traditional counterweight base depends entirely on its own weight and base area, and its overturning moment is a fixed value. This means that the counterweight must be determined according to the possibility of extreme winds during the design phase, resulting in the base being in a redundant state of "overperformance" in most non-windy weather conditions. More importantly, it cannot sense changes in wind force, nor can it actively and dynamically enhance its own stability when the wind load suddenly increases; it merely passively bears the load as a "dead weight."

[0003] Secondly, they are neither economical nor portable. Relying solely on weight to withstand all conditions results in bulky and heavy bases. This not only increases raw material costs but also makes transportation, hoisting, and on-site placement extremely difficult and expensive, significantly reducing their practicality, especially for information boards that need to be temporarily set up or frequently moved.

[0004] In addition, although there are some solutions that involve increasing the base area or using anchored foundations, these methods are often complex to construct, damage the ground, and also lack self-adaptive capabilities.

[0005] Therefore, there is an urgent need in this field for a counterweight base that can overcome the above-mentioned defects. It should be able to break away from the traditional idea that "weight determines everything" and achieve intelligent and adaptive enhancement of anti-overturning moment through ingenious mechanical structure design. In this way, while ensuring the same safety, the weight of the base can be significantly reduced, the overall cost can be reduced, and the deployment flexibility can be improved. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a windproof and anti-tipping base for information board panels, which can achieve adaptive enhancement of anti-tipping moment, thereby significantly reducing the weight of the base, reducing the overall cost, and improving the flexibility of its deployment while ensuring the same safety.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a windproof and tilt-proof base for an information board panel, comprising: The base housing has a mounting flange on its top for mounting the panel columns; A swing beam is horizontally set and rotatably connected to the top of the base box via a hinge shaft, the axis of which is aligned with the front-rear direction of the panel column. Two pendulum counterweights are suspended from both ends of the swing beam via pendulum rods, and the two pendulum counterweights are located on the front and rear sides of the panel column, respectively; and Two transmission arms are provided, with their bottom ends connected to the two ends of the swing beam, and their upper ends extending upward through the perforation at the top of the base box and hinged to the panel column.

[0008] Furthermore, the upper end of the swing arm is connected to the swing beam via a first ball hinge.

[0009] Furthermore, a bearing seat is fixedly installed on the base housing, the hinge shaft is supported on the bearing seat by the bearing, one end of the hinge shaft is connected to a rotation damper, and the housing of the rotation damper is fixed to the bearing seat or the base housing.

[0010] Furthermore, the rotating damper is a viscous fluid damper.

[0011] Furthermore, a return torsion spring is sleeved on the hinge shaft, with one end of the return torsion spring fixed on the hinge shaft and the other end fixed on the bearing seat.

[0012] Furthermore, the top end of the transmission arm is connected to the panel column via an elastic connector.

[0013] Furthermore, an elastic sealing sleeve is provided on the perforation, and the elastic sealing sleeve is sealed to the transmission arm.

[0014] The beneficial effects of this utility model are: The aforementioned information board panel's windproof and tilt-proof base has at least the following advantages: 1. The wind-resistant overturning base of this information board panel constructs a dynamic negative feedback system through the coordinated action of the swing beam, pendulum counterweights, and transmission arm. When wind load causes the panel's support column to overturn, this movement forces the swing beam to rotate via the transmission arm, which in turn causes the two pendulum counterweights to move in the opposite direction of the overturning due to inertia, thus dynamically generating a powerful restoring torque. The stronger the wind and the stronger the panel's overturning tendency, the stronger the restoring torque will be. By combining "static resistance" with "dynamic countermeasures," safety under sudden gusts of wind is significantly improved.

[0015] 2. Because the stability of the wind-resistant and tilt-proof base of this information board panel does not entirely rely on the foundation counterweight, but rather largely on the aforementioned dynamic restoring torque, it does not need to rely entirely on massive mass to resist the most extreme wind forces, unlike traditional bases. This means that while achieving the same wind resistance standard, the base box and its internal foundation counterweight of this invention can be made lighter and smaller. This leads to reduced material costs, as well as convenience and cost savings during transportation, hoisting, and deployment, making it particularly suitable for temporary or mobile information board scenarios.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 4 This utility model provides a windproof and anti-tipping base for an information board panel, including a base box 100, a swing beam 200, two pendulum counterweights 300 and two transmission arms 400.

[0020] Specifically, the base housing 100 is a hollow, rigid structure, which can be welded from steel plates. Its interior can be filled with sand or concrete as a foundation counterweight to reduce manufacturing costs. A mounting flange is welded to the top of the base housing 100 for reliable connection to the information board's column 110 via bolts. This serves as the structural interface between the entire device and the information board.

[0021] The swing beam 200 is rotatably connected to the inner top of the base housing 100 via a hinge shaft 210. The axis of the hinge shaft 210 is aligned with the front-to-back direction of the information board column 110. Two pendulum counterweights 300 are made of high-density material (such as cast iron or lead) and are suspended from the left and right ends of the swing beam 200 via pendulum rods 310, respectively. When the information board column 110 is erected via the mounting flange, the two pendulum counterweights 300 are positioned precisely on the front and back sides of the column 110.

[0022] The two drive arms 400 are force transmission components connecting the swing beam 200 and the panel column 110110. The lower ends of the two drive arms 400 are connected to both ends of the swing beam 200, and the upper ends pass upward through the through holes in the top of the base box 100, forming a hinged connection with the panel column 110110. This hinge can be a universal hinge, allowing for small angular displacements in all directions.

[0023] When a gust of wind blows towards the information board panel, the panel causes the support column 110 to tilt forward (or backward). This movement forces the two drive arms 400 to push and pull at the hinge point, thereby driving the swing beam 200 to rotate around its hinge axis 210. At this time, due to the law of inertia, the pendulum counterweights 300 suspended at both ends of the beam will try to maintain their original static or dynamic state. For example, when the panel tilts forward, the rear pendulum will have a tendency to swing backward, which will generate a torque to resist the forward tilt of the panel; at the same time, the front pendulum will swing forward, reducing the forward tilt load. This pair of pendulums, through their inertial motion, together constitute a strong "restoring torque" in the opposite direction to the tilting tendency, dynamically enhancing the stability of the base. Compared with the static counterweight in the prior art, this solution achieves a shift from "passive load-bearing" to "active wind resistance," providing a much greater anti-tipping capability than traditional solutions under the same weight.

[0024] In this embodiment, the upper end of the pendulum 310 is connected to the swing beam 200 via a first ball joint 320. The ball joint provides a spherical kinematic pair, allowing the pendulum 310 to swing slightly in any direction. In practical applications, the tilting motion of the information board may not be purely forward or backward, but may be accompanied by slight torsion or lateral swaying. If a conventional hinge is used, the mechanism may jam or generate additional internal stress due to motion mismatch. The introduction of the ball joint ensures that the pendulum can respond freely and smoothly under any complex force conditions, enabling the entire inertial stabilization system to adapt to disturbances in multiple directions, thus improving the reliability and effectiveness of the mechanism.

[0025] In this embodiment, a bearing seat 120 is fixedly installed on the base housing 100, and the hinge shaft 210 is supported in the bearing seat 120 by a bearing, realizing smooth rotation of the swing beam 200 with low friction and high precision. Furthermore, a rotation damper 130 is connected to one end of the hinge shaft 210, which is preferably a viscous fluid damper.

[0026] In operation, the bearing support ensures transmission efficiency, allowing wind power to be responsively converted into the rotation of the crossbeam. When the pendulum swings and drives the crossbeam to rotate, the damper 130 generates a resistance torque proportional to the rotational speed. This resistance torque continuously consumes the kinetic energy of the pendulum system, converting it into heat energy. Its direct effect is: Suppressing oscillations: Preventing the pendulum from swinging back and forth endlessly during the intervals between gusts, causing its motion to decay rapidly.

[0027] Smooth Response: This prevents the mechanism from reacting too violently to minor changes in wind speed, resulting in a smoother and more controllable output of stable torque. The use of viscous fluid dampers (such as a housing and rotor structure filled with silicone oil) is a mature technology, offering a good linear relationship between damping force and speed, stable and reliable performance, and a long service life.

[0028] As another preferred embodiment, the information board panel's windproof overturning base is fitted with a return torsion spring 220 on the hinge shaft 210. One end of the torsion spring is fixed to the hinge shaft 210, and the other end is fixed to the bearing seat 120.

[0029] The return torsion spring 220 provides an elastic return force to the swing beam 200, ensuring it always points to the horizontal equilibrium position. Its main function is to provide a return force when the wind load decreases or disappears. Assisted reset: After the damper 130 has consumed the main kinetic energy, the torque of the torsion spring can actively pull the swing beam 200 back to the horizontal neutral position, so that the pendulum is suspended vertically again, preparing for the next wind-resistant action.

[0030] Provides initial stability: In windless conditions, the preload of the torsion spring keeps the system in a neutral position, eliminating minor wobbling that may be caused by mechanism clearances and enhancing the static stability of the base.

[0031] Furthermore, in practical implementation, the top end of the transmission arm 400 can be connected to the panel column 110110 via an elastic connector 500. This elastic connector 500 can be a high-strength rubber block or a polyurethane block. The elastic connector 500 acts as a "mechanical filter" and "buffer" here. It can absorb and mitigate the instantaneous strong impact force (such as a sudden gust of wind) from the panel column 110110, protecting the internal mechanical mechanisms of the base from damage.

[0032] Additionally, a resilient sealing sleeve 600 can be installed on the perforation at the top of the base housing 100, forming a sealed connection with the transmission arm 400. The base housing 100 houses a precision swing mechanism that requires protection. The resilient sealing sleeve 600 (made of rubber or silicone) effectively seals the gap between the transmission arm 400 and the perforation. This does not significantly impede the necessary up-and-down and tilting movements of the transmission arm 400, while effectively preventing external rainwater, dust, and corrosive gases from entering the base housing 100.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
