Description

Outdoor display rack with intelligent wind-resistant and rapid retraction function Technical Field

[0001] This invention relates to the field of outdoor display equipment technology, and in particular to a multifunctional intelligent outdoor protective display rack that integrates wind-resistant and rapid shrinkage control for use in various outdoor scenarios such as commercial advertising, corporate displays, and cultural dissemination. Background Technology

[0002] With the increasing number of outdoor activities, the demand for quick-to-set-up and safe, reliable temporary outdoor display stands is growing. For example, outdoor exhibitions such as product launches and trade fairs, as well as school recruitment campaigns, require the rapid erection of temporary outdoor display stands. Simultaneously, traffic police and road administration departments also need temporary display stands to display road condition information during road construction. These situations all demand that display stands be installed quickly and maintain structural stability and reliability.

[0003] However, existing outdoor display racks, such as the windproof e-commerce user display rack with publication number CN115346456A, mostly adopt a fixed or foldable structure with a large overall frame. In order to meet the display height requirements for outdoor use, the display position of this type of display rack needs to be set high, which poses certain safety hazards in the complex and ever-changing outdoor environment.

[0004] In particular, unpredictable wind changes can easily cause the entire display rack to be blown over, or the connecting parts of the main frame of the display rack to break off due to the wind. Once broken, the main frame will fall off, which may cause secondary damage to surrounding people and facilities.

[0005] To address the aforementioned issues, it is essential to design a novel outdoor display rack with intelligent wind-resistant and rapid retraction capabilities. While simply employing a motor-driven lifting or folding mechanism, coupled with electronic devices such as wind speed sensors, could accomplish the task, this would significantly increase the overall cost and weight of the display rack. Furthermore, outdoor use would make the electronic equipment more prone to malfunction, hindering the product's widespread adoption. Therefore, the retraction mechanism of this display rack must utilize a highly reliable mechanical structure suitable for outdoor use, with careful consideration given to cost and weight control. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an outdoor display rack that integrates wind-resistant rapid retraction control, enabling intelligent protection of the display frame to quickly flip and descend under strong wind conditions. The rack is reliable in structure and easy to use.

[0007] The objective of this invention is achieved through the following technical solution: an outdoor display rack with intelligent wind-resistant and rapid retraction function, comprising:

[0008] At least one base that is stably placed on the ground;

[0009] A multi-section support arm is detachably hinged to the base, and the end of the multi-section support arm is provided with a tilting mechanism for wind force adaptation;

[0010] The flipping mechanism includes:

[0011] A display frame mounting base is provided at the end of a multi-section support arm, and the display frame mounting base is rotatable relative to the end section of the multi-section support arm;

[0012] An elastic telescopic head, one end of which contacts or approaches the display frame mounting base via a spring.

[0013] A hinged mounting shaft is hinged to the display frame mounting base.

[0014] The limiting link has one end hinged to the display frame mounting base and the other end slidably connected. The function of the limiting link is to support the display frame mounting base in two stable positions: vertical display and horizontal flip.

[0015] The display frame is detachably fixed to the flipping mechanism;

[0016] The flipping mechanism uses wind power to rotate the display frame mounting base, compressing the spring in the elastic telescopic head. When the wind force exceeds the spring's restoring force, the display frame mounting base quickly flips, causing the display frame to flip from a vertical to a horizontal position. By setting up the flipping mechanism, the display frame can quickly flip to a horizontal position under strong winds, effectively reducing wind load and protecting the display rack from tipping over.

[0017] Preferably, one end of the elastic telescopic head is a transition surface, and the upper and lower edges of the transition surface are chamfered. By setting the chamfer on the transition surface of the elastic telescopic head, noise generated by collision between the transition surface and the display frame mounting base can be avoided, thus improving comfort.

[0018] Preferably, the hinge joint between the limiting link and the display frame mounting base can be broken into two parts. This allows for easy assembly and disassembly, provides more options, and enhances usability.

[0019] Preferably, it also includes a linkage lowering mechanism for rapidly lowering the display frame, the linkage lowering mechanism comprising:

[0020] A linkage belt is installed on the third rotating arm, and one end of the linkage belt is fixed to the third rotating arm;

[0021] A notch is provided at the hinge joint between the second and third rotating arms, and the linkage belt passes through the notch;

[0022] An extension connection portion is located on the side of the hinge mounting shaft facing the rotating arm, and the linkage belt connects to the extension connection portion after passing through the notch;

[0023] The stop block mounting part is provided on the second rotating arm;

[0024] The stop block is installed on the stop block mounting part;

[0025] The stop shaft is fixed on the third rotating arm;

[0026] The stop block engages with the stop shaft. By setting up a linkage lowering mechanism, the display frame can be quickly lowered from a horizontal position to a vertical low position, preventing it from tipping over and ensuring continued display.

[0027] Preferably, the stop block is located below the linkage belt. By positioning the stop block below the linkage belt, locking and releasing of the third rotating arm can be achieved.

[0028] Preferably, the bottom of the stop block has a downward pressing engagement tooth that meshes with the surrounding engagement tooth on the stop shaft. By engaging the downward pressing engagement tooth at the bottom of the stop block with the surrounding engagement tooth on the stop shaft, the third rotating arm can be quickly locked.

[0029] Preferably, the middle section of the stop block has an elastically deformable spring plate. By setting the spring plate, the stop block can be restored after it bounces back, ensuring the reliability of the progressive retraction and extension movement.

[0030] Preferably, the spring plate and the stop block body are separate structures. By separating the spring plate from the stop block body, the spring plate is prevented from falling off, thus improving structural reliability.

[0031] Preferably, the stop block is provided with multiple spring plates. By providing multiple spring plates, the balance and stability of the stop block are improved.

[0032] As a preferred option, the elastic force of the multiple spring plates is optimized to achieve balance. By optimizing the elastic force design of the spring plates, a balance of elastic force is achieved, ensuring reliable motion.

[0033] Preferably, the elasticity and length of the linkage belt are optimized to accommodate the operational needs of the linkage lowering mechanism, ensuring smooth operation of the display frame's retraction and extension process from vertical to horizontal and back to vertical. Optimizing the elasticity and length of the linkage belt ensures a smooth and reliable retraction and extension process for the display frame.

[0034] In summary, the present invention has the following advantages compared with the prior art:

[0035] This invention discloses an outdoor display rack with a modular design, including a base, multi-section support arms, a flipping mechanism, a linked lowering mechanism, and a display frame. The rack integrates intelligent control for wind-resistant rapid retraction, enabling the display frame to quickly flip from a vertical to a horizontal position under strong winds, and then rapidly descend from a horizontal position to a low vertical position. The entire process is mechanically stable and reliable, effectively protecting the structural safety of the display rack. Compared to existing technologies, this invention represents a significant advancement in three aspects: First, the intelligent wind-resistant rapid retraction control broadens the product's applicable environment, allowing it to adapt to complex and changing outdoor conditions; second, the flipping and linked lowering mechanisms are ingeniously and rationally designed, ensuring reliable and smooth movement; third, the modular design facilitates installation and transportation, making it convenient to use and cost-effective. Overall, this invention features a scientifically sound design, precise and reliable control, a long service life, and wide applicability, achieving excellent display effects, reliable structure, and ease of use. It represents a significant advancement in outdoor display rack technology and offers substantial social and economic benefits. Attached Figure Description

[0045] First, it should be noted that the following description, by way of example, illustrates the structural composition, features, and advantages of the outdoor display rack with intelligent wind-resistant and rapid retraction function according to the present invention; however, all descriptions should not be construed as limiting the present invention in any way. In this document, the technical terms "first" and "second" are used only for distinguishing purposes and are not intended to indicate their order or relative importance, and the technical term "connection (or linking, etc.)" covers components directly and / or indirectly connected to another component.

[0046] Furthermore, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the various figures, the present invention still allows for any combination or deletion among these technical features (or their equivalents) without any technical obstacle. Therefore, these further embodiments according to the present invention should also be considered within the scope of this description. Additionally, for the sake of simplifying the drawings, identical or similar parts and features may be indicated only in one or more places in the same figure.

[0047] Example 1

[0048] Example 1 describes an outdoor display rack with intelligent wind-resistant rapid retraction function. By using a simple mechanical force transmission and amplification method, when the wind force reaches a preset threshold, the rapid retraction mechanism is automatically triggered to quickly lower the main body of the display rack from a high position, thereby reducing the impact of wind on the display rack, thus preventing the display rack from tipping over or being damaged, and reducing the potential risk of damage to the surrounding area.

[0049] First, it includes at least one base 1 that is stably placed on the ground. The base 1 can improve its stability, for example, by setting a counterweight or any weight inside or on its upper part; a multi-section support arm 2 that is hinged to the base 1 in a lockable / fixed manner; a flipping mechanism 3 for wind-adaptive operation is provided at the end of the multi-section support arm 2; and a display frame 5 that is detachably fixed in the flipping mechanism 3.

[0050] The multi-section support arm 2 includes: a first rotating arm 21, a second rotating arm 22, and a third rotating arm 23, which are hinged to each other from bottom to top in a lockable / fixed manner. To facilitate the explanation of the structure of the tilting mechanism 3, coordinate systems are provided in Figures 7-8 for auxiliary illustration. The tilting mechanism 3 includes:

[0051] 1. The display frame mounting base 31, relative to the third rotating arm 23, is fixed on the Y-axis and cannot move, but can rotate around the origin on the Z-axis and can slide on the X-axis;

[0052] 2. An elastic telescopic head 32 with a first U-shaped opening 01 in the Y-axis direction has a transition surface 321 at its free end. The elastic telescopic head 32 is movably mounted at the free end of the third rotating arm 23 and can move away from or towards the third rotating arm 23 along the X-axis direction. Specifically, a second U-shaped opening 02 is provided on the third rotating arm 23 extending towards the free end along the Y-axis direction. The size and position of the second U-shaped opening 02 are consistent with the first U-shaped opening 01. The two cooperate to form a flat slide rail channel 06 with opposite openings and parallel upper and lower sides. Elastic telescopic movement is achieved by setting a guide pin 03, a spring 04, and a guide rail 05 with a limit.

[0053] 3. The hinged mounting shaft 33 has its middle part set in the slide rail channel 06, and its two exposed ends are hinged to the display frame mounting base 31, and can slide in the X-axis direction;

[0054] 4. One end of the limiting link 34 is adjustablely connected to the flat slide rail channel 06 via a sliding seat 07, and the link body can rotate in the Z-axis direction. The other end is hinged to the display frame mounting base 31, with the hinge position below the connection point of the hinge mounting shaft 33. The function of the limiting link 34 is to pull or support the display frame 5, keeping the hinge mounting shaft 33 in two stable positions: one is the display state, as shown in Figures 2 and 7, and the other is the folded state, as shown in Figure 4. The setting of the limiting link 34 allows the display frame 5 to only flip upwards. This is because when the display frame 5 flips downwards, the hinge mounting shaft 33 needs to move to the far end within the slide rail channel 06, which is restricted by the closed end of the channel. This design is because the space for the display frame 5 to flip downwards is restricted by other components such as the second rotating arm, and the two will collide, thus preventing downward flipping. Upward flipping, however, is not restricted by space.

[0055] In this way, the flipping mechanism 3 can achieve wind-adaptive flipping function. In addition, it is necessary to explain the assembly requirements and operating principle of the key components of the flipping mechanism. During assembly, the first step is to ensure that the elastic telescopic head 32 is in a fully extended state, and to adjust the sliding seat 07 so that the hinge mounting shaft 33 is located at the end of the slide rail channel 06, leaving a small gap between the transition surface 321 and the display frame mounting seat 31.

[0056] The operating principle is that the elastic telescopic head 32 always has a certain elastic coefficient under the action of the spring 04. When the wind force acts on the display frame 5, it will generate a torsional torque, causing the display frame mounting base 31 to rotate around the hinge mounting shaft 33 at a certain angle, compressing the spring 04 of the elastic telescopic head 32. The free end of the elastic telescopic head 32 is forced to move, thereby driving the transition surface 321 to move closer to the third rotating arm 23.

[0057] As the wind force increases, the rotation angle and the compression of spring 04 gradually increase. When the wind force exceeds the restoring force of spring 04, the restoring force of spring 04 will cause the display frame mounting base 31 to undergo a rapid abrupt change, that is, a rapid rotation switch that flips the display frame 5 from a vertical state to a horizontal state. During this process, the limiting link 34 enters the transition surface 321 from below and moves upward. The horizontal state of the display frame 5 allows the limiting link 34 to reach the upper edge of the transition surface 321, rather than completely disengaging. This design facilitates resetting. It is best to have chamfers on the upper and lower edges of the transition surface 321, which is more conducive to achieving smooth resetting. In addition, the limiting link 34 shown in the figure is integrated with the hinge of the display frame mounting base 31. In practice, a section larger than or equal to the width of the transition surface can be cut off from the middle. The purpose of disconnection is to avoid contact with the transition surface 321. The advantage of this design is that the hinge position of the limiting link 34 and the display frame mounting base 31 can be set with greater freedom, but the stability is not as good as the integrated structure. At this time, the force arm of the wind load acting on the display frame 5 is greatly reduced. At this time, the position of the limiting link 34 is the transition surface 321. The elastic telescopic head 32 also returns to the initial position under the action of the spring 04.

[0058] However, simply flipping the display frame 5 to a horizontal position reduces wind load, but the height of the display frame 5 is not lowered, and there is still a risk of tipping over. Therefore, a linkage lowering mechanism 4 is needed to enable the display frame 5 to descend quickly.

[0059] The specific structure of the linkage descent mechanism 4 includes:

[0060] 1. Linkage belt 41: The linkage belt should be flexible and elastic, and be able to withstand tensile deformation.

[0061] 2. Notch 42: Located at the hinge between the second rotating arm 22 and the third rotating arm 23, for the drive belt 41 to pass through.

[0062] 3. Extension connecting part 43: Located on the side of the hinge mounting shaft 33 facing the swing arm, used to connect the linkage belt 41. One end of the linkage belt 41 is fixed to the third swing arm 23, and the other end passes through the notch 42 and connects to the extension connecting part 43.

[0063] 4. Stop block 44: It has an inverted cone shape, with a downward pressing engagement tooth 441 at the bottom and an outwardly extending spring plate 442 in the middle section. The spring plate 442 causes the stop block 44 to spring up towards the distal end and constrains the stop block 44 within a certain range of motion. The stop block 44 is located below the linkage belt 41.

[0064] 5. Stop shaft 45: fixed to the third rotating arm 23, with a ring of surrounding meshing teeth 451 that engage with the pressing meshing teeth 441 on its outer ring.

[0065] 6. Stop block mounting part 46: A fixing part provided on the second rotating arm 22, which matches the shape of the stop block 44, and also includes a mounting part for the spring plate 442. Its position corresponds to the surrounding meshing teeth 451.

[0066] When the display frame 5 is in the vertical display state, as shown in Figures 1-2, the linkage belt 41 is in a taut state. At this time, the meshing teeth 441 of the stop block 44 mesh with the surrounding meshing teeth 451, so that the third rotating arm 23 is in a locked and stable state.

[0067] When the display frame 5 is flipped to a horizontal position by the wind, the hinge mounting shaft 33 moves to one side of the rotating arm, causing the extension connecting part 43 to move synchronously, so that the linkage belt 41 changes from its original taut state to a relaxed state. At this time, under the action of the spring plate 442, the stop block 44 disengages from the engagement state with the surrounding meshing teeth 451, and the third rotating arm 23 also changes from the locked state to the rotatable state.

[0068] Under its own weight, the third rotating arm 23 quickly rotates downwards around the hinge. This downward rotation causes the slack linkage belt 41 to tighten again, pressing tightly against the area around the hinge. Finally, the display frame 5 moves down to a stable low position, and the third rotating arm 23 is locked again.

[0069] In this way, the display box 5 can quickly descend from a high horizontal position to a low vertical position, and can still continue to display while avoiding tipping over.

[0070] To prevent the spring plate 442 from easily detaching after repeated use, the middle section of the stop block 44 can be broken into two parts, meaning the spring plate 442 and the stop block body are separate structures. The two are connected by a hinge or similar means. This way, when the spring plate 442 undergoes elastic deformation, the entire stop block 44 will not shift, thus ensuring the normal function of the spring plate 442.

[0071] Furthermore, regarding the spring plates 442, they can be configured as multiple plates distributed, that is, multiple spring plates can be placed at different positions around the stop block 44. This can give the stop block 44 better balance and stability. The elastic force of each spring plate can also be optimized and balanced through design.
