Description

Technical Field

[0001] This utility model relates to the field of access equipment, and in particular to a holographic fan advertising barrier arm and a holographic fan advertising barrier. Background Technology

[0002] Existing holographic fan advertising barrier structures, such as Figure 6 and Figure 7 As shown, the holographic fan and protective frame are located on one side of the barrier arm, allowing the projected image to be displayed only on one side. For two-way traffic barriers, this means information can only be conveyed to pedestrians or vehicles in one direction, failing to simultaneously reach audiences in both directions. This significantly reduces the coverage of information dissemination and diminishes the effectiveness of advertising or information display. Furthermore, the protective frame's exclusive installation on one side of the barrier arm can easily shift the barrier's center of gravity, disrupting its balance under stress. When subjected to wind, vibration, or other external forces, the barrier arm may experience significant stress concentration on the side where the protective frame is installed, making it more prone to bending, deformation, or damage, and exhibiting low compressive strength. Additionally, the existing holographic fan advertising barrier's installation structure is complex, difficult to operate, and challenging to install. Utility Model Content

[0037] This utility model embodiment discloses a holographic fan advertising barrier arm and a holographic fan advertising barrier.

[0038] Please see Figures 1-5 An embodiment of the holographic fan 2 advertising barrier arm 1 provided in this utility model includes: holographic fan 2, barrier arm 1 and protective frame 8;

[0039] The holographic fan 2 includes fan blades 21 and a fan base 22, with the middle part of the fan blades 21 connected to the fan base 22;

[0040] At least one mounting structure is provided on both sides of the barrier gate arm 1. The fan base 22 is fixed to the barrier gate arm 1 through the mounting structure, and the fan blade 21 is located on the outside of the barrier gate arm 1.

[0041] The protective frame 8 is a closed structure with a accommodating space, used to protect the holographic fan 2. The middle of the protective frame 8 passes through the barrier gate 1 and is fixed to the barrier gate 1. The protective frame 8 is symmetrically arranged along the center line of the length direction of the barrier gate 1. The holographic fan 2 is located between the protective frame 8 and the barrier gate 1.

[0042] Understandably, in practical implementation, mounting structures are provided on both sides of the barrier gate arm 1. By fixing the fan base 22 of the holographic fan 2 to the mounting structure, the holographic fan 2 can be installed on either side of the barrier gate arm 1. In the case of a two-way barrier gate, the fan base 22 of the holographic fan 2 is fixedly installed on the mounting structures on both sides of the barrier gate arm 1, so that the holographic fan 2 is set on both sides of the barrier gate arm 1 for projection display, while taking into account the audience in both directions, thus improving the display effect of advertising or information. The protective frame 8 passes through the middle of the barrier gate arm 1 and is fixed to the barrier gate arm 1, providing a protective space for the holographic fan 2 on both sides of the barrier gate arm 1, effectively blocking external physical impacts, dust, moisture and other adverse factors, ensuring that the holographic fan 2 on both sides of the barrier gate arm 1 can operate stably in various environments. By symmetrically setting the protective frame 8 on the barrier gate arm 1, it can promote the balance of forces on both sides of the barrier gate arm 1, making the barrier gate arm 1 more stable when subjected to external pressure, and improving the compressive strength of the barrier gate arm 1.

[0043] In a more specific embodiment, the protective frame 8 includes display panels 82 on both sides and a border 81 around the perimeter.

[0044] In a more specific embodiment, the display panels 82 on both sides of the protective frame 8 are transparent panels. It is understood that the transparent panels allow light to pass through completely from one side, and the image projected by the holographic fan 2 on the other side of the transparent panels can be clearly seen.

[0045] In a more specific embodiment, the display panel 82 is made of a lightweight and transparent material, ensuring light transmission while reducing the burden on the barrier arm 1. In some more specific embodiments, the display panel 82 is made of acrylic material with a light transmittance of over 92%, and is relatively lightweight and impact-resistant; in other more specific embodiments, the display panels 82 on both sides of the protective frame 8 are made of polycarbonate material, which has the advantages of high strength, high toughness, high transparency, and relatively light weight.

[0046] In a more specific embodiment, the frame 81 around the protective frame 8 is made of lightweight material, including acrylic, PVC board or aluminum composite panel, etc. In some more specific embodiments, the frame 81 is also made of lightweight and transparent material. It can be understood that the entire protective frame 8 is a transparent structure, which enhances the sense of technology and makes it more attractive.

[0047] In a more specific embodiment, the protective frame 8 is a flat cuboid structure, with its height significantly smaller than its length and width. This allows it to not only accommodate the holographic fan 2 well, but also provides a larger display area to prominently showcase the advertising content. In some more specific embodiments, to enhance the design, the display panel 82 of the protective frame 8 can be rectangular, elliptical, irregularly shaped, or otherwise.

[0048] In a more specific embodiment, mounting openings are provided on the middle of both sides of the frame 81 of the protective frame 8. It can be understood that the mounting openings are used to pass through the barrier gate arm 1 to ensure that the barrier gate arm 1 is installed in the middle of the protective frame 8, thereby maximizing the force balance of the barrier gate arm 1.

[0049] In a more specific embodiment, an elastic sealing ring is provided at the gap between the mounting opening and the barrier arm 1. It is understood that, in practice, on the one hand, the elastic sealing ring is placed between the mounting opening and the barrier arm 1, achieving a seal between them under the elastic action of the ring, preventing moisture, dust, etc., from entering the protective frame 8 through the gap between the mounting opening and the barrier arm 1, thus affecting the operation of the fan; on the other hand, during the raising and lowering of the barrier arm 1, some vibration is inevitably generated. The elastic sealing ring can absorb and buffer this vibration, reducing the impact of the barrier arm 1 on the protective frame 8. This helps protect the structural integrity of the protective frame 8, preventing loosening or damage due to vibration; furthermore, the buffering effect of the elastic element can reduce friction and collision noise between the barrier arm 1 and the protective frame 8, providing a quieter environment for the surroundings.

[0050] In a more specific embodiment, the resilient sealing ring is secured to the inner wall of the mounting opening by screws or glue.

[0051] In a more specific embodiment, the material of the elastic sealing ring is silicone rubber, polyurethane, etc.

[0052] In a more specific embodiment, steps are provided at the edges of the openings on both sides of the frame 81. It can be understood that the steps are used to install the display panel 82. During installation, the edge of the display panel 82 abuts against the steps of the frame 81. The step setting provides a clear installation position for the display panel 82, making the installation process faster and more accurate.

[0053] In a more specific embodiment, such as Figure 9 As shown, the edge of the display panel 82 is covered with an elastic seal 821. It is understood that, in practical implementation, the elastic seal 821 covering the edge of the display panel 82 can effectively prevent water from entering through the gap between the display panel 82 and the frame 81, protecting the inner side of the display panel 82 and the internal structure of the protective frame 8 from moisture; simultaneously, during installation, the elastic seal 821 covering the edge of the display panel 82 can prevent damage to the edge of the display panel 82; during the operation of the barrier arm, the elastic seal 821 can fill the gap between the display panel 82 and the frame 81, ensuring that the edge of the display panel 82 is tightly fitted to the frame 81, preventing displacement and collision of the edge of the display panel 82 that could cause the display panel 82 to crack.

[0054] In a more specific embodiment, the material of the elastic seal 821 is silicone rubber, polyurethane, etc. In a more specific embodiment, the protective frame 8 also includes a pressure ring and fasteners. The pressure ring abuts against the edge of the display surface of the display panel 82, and the fasteners are used to fix the pressure ring and the display panel 82 to the step of the frame 81. The pressure ring is used to prevent the pressure of the fasteners from acting directly on the display panel 82.

[0055] In a more specific embodiment, the fastener is a screw; it is understood that, in practice...

[0056] The pressure ring 83 is located on the outer edge of the display surface of the display panel 82. The pressure ring 83 has fixing holes, and the step has threaded grooves corresponding to the fixing holes. It can be understood that when installing the display panel 82, the pressure ring 83 secures the display panel 82 to the step of the frame 81, and the end of a screw passes through the fixing hole and into the threaded groove to fix the pressure ring 83 and the display panel 82 to the step of the frame 81. The pressure ring 83 prevents the pressure of the screw from directly acting on the display panel 82, thus avoiding damage to the display panel 82 due to excessive pressure and improving the safety of the display panel 82 during installation. In some more specific embodiments, the fastener is a clamping member, which presses down on the pressure ring 83 and the display panel 82 in sequence, fixing both the pressure ring 83 and the display panel 82 to the step of the frame 81.

[0057] In a more specific embodiment, the inner surface of the frame 81 is connected to the outer surface of the barrier arm 1 via an L-shaped piece 6. The L-shaped piece 6 is installed at the right angle formed between the inner surface of the frame 81 and the outer surface of the adjacent barrier arm 1. The L-shaped piece 6 includes two mutually perpendicularly connected first vertical surfaces and second vertical surfaces. Fixing holes are provided on both the first and second vertical surfaces. Threaded grooves are provided on both the inner surface of the frame 81 and the outer surface of the barrier arm 1. It can be understood that during installation, the end of a screw is screwed into the threaded groove on the inner surface of the frame 81 through the fixing hole of the first vertical surface to achieve the connection between the first vertical surface of the L-shaped piece 6 and the inner surface of the frame 81. The end of a screw is screwed into the threaded groove on the outer surface of the barrier arm 1 through the fixing hole of the second vertical surface to achieve the connection between the second vertical surface of the L-shaped piece 6 and the outer surface of the barrier arm 1. Thus, the fixed connection between the frame 81 and the barrier arm 1 is completed.

[0058] In a more specific embodiment, the mounting structure includes a mounting groove 7 formed on the side of the barrier arm 1. The mounting groove 7 is used to embed and fix the fan base 22 of the holographic fan 2. It is understood that the barrier arm 1 is driven by a motor located at one end, causing the barrier arm 1 to rotate around that end, thereby realizing the opening and closing of the gate. In this embodiment, by embedding the fan base 22 into the barrier arm 1, the distance from the end face of the holographic fan 2 to the barrier arm 1 can be reduced, thereby reducing the thickness of the frame 81 and the overall weight of the protective frame 8, which helps to reduce the burden on the motor used to drive the rotation of the barrier arm 1 and the barrier arm 1.

[0059] In a more specific embodiment, the opening shape of the mounting groove 7 is the same as the shape of the fan base 22, allowing the side of the fan base 22 to fully contact the groove, thus providing a limiting function to prevent the fan base 22 from shaking and enabling precise positioning during installation, thereby improving installation efficiency. In some more specific embodiments, the fan base 22 is a cylinder, and the opening shape of the mounting groove 7 is circular; in some more specific embodiments, the fan base 22 is a cuboid, and the opening shape of the mounting groove 7 is rectangular.

[0060] In a more specific embodiment, multiple mounting grooves 7 are provided on both sides of the barrier arm 1, so that multiple holographic fans 2 are arranged side by side on the barrier arm 1.

[0061] In a more specific embodiment, the mounting structure further includes a U-shaped bracket 4 and extensions 42 disposed at both ends of the opening of the U-shaped bracket 4. The fan base 22 of the holographic fan 2 is embedded in the recess 41 of the U-shaped bracket 4, and the recess 41 of the U-shaped bracket 4 is embedded in the mounting groove 7. The extensions 42 abut against the outer edge of the mounting groove 7. The bottom of the fan base 22 is fixedly connected to the bottom of the U-shaped bracket 4, and the extensions 42 are fixedly connected to the outer edge of the mounting groove 7. This embodiment uses only a U-shaped bracket 4 to install the holographic fan 2 onto the barrier arm 1. The structure is simple, the operation is convenient, the assembly difficulty is low, and the required parts are few. The corresponding mold liquid is simple, and the production cost is low.

[0062] In a more specific embodiment, the U-shaped bracket 4 has a first opening at its bottom, and the fan base 22 has a first threaded groove corresponding to the first opening. The bottom of the U-shaped bracket 4 is fixedly connected to the bottom of the fan base 22 by a first screw passing through the first opening and screwing into the first threaded groove. In other more specific embodiments, the bottom of the U-shaped bracket 4 is connected to the bottom of the fan base 22 by riveting or snap-fit ​​connection.

[0063] In a more specific embodiment, the extensions 42 at both ends of the U-shaped bracket 4 are provided with second openings, and the outer edge of the mounting groove is provided with second threaded grooves corresponding to the second openings. The extensions 42 of the U-shaped bracket 4 are fixedly connected to the outer edge of the mounting groove by passing through the second openings and entering the second threaded grooves with second screws. In some more specific embodiments, the bottom of the U-shaped bracket 4 is connected to the bottom of the fan base 22 by riveting or snap-fit ​​connection. In other more specific embodiments, a clamp is provided on the outer edge of the mounting groove 7, and the U-shaped bracket 4 is fixed to the mounting groove 7 by placing the extensions 42 at both ends of the opening of the U-shaped bracket 4 under the clamp.

[0064] In a more specific embodiment, the barrier gate arm 1 is provided with two partitions 14 of the same length as the barrier gate arm 1 and arranged side by side along the width direction of the barrier gate arm 1. The two partitions 14 divide the space inside the arm into a first space 11, a second space 12, and a third space 13. The first space 11 and the third space 13 are both used to set the mounting groove 7. The partitions 14 are the bottom of the mounting groove 7. The bottom of the mounting groove and the bottom of the U-shaped bracket 4 are provided with wire openings. The second space 12 is used to store the transmission wires connected to the fan base 22 that are led out from the wire openings in the first space 11 and the third space 13. It can be understood that, in specific implementation, the first space 11 and the third space 13 are both the mounting space for the fan base 22, and the second space 12 is the wire leading space. The transmission wires of the holographic fan 2 pass out from the wire openings at the bottom of the U-shaped bracket 4 and the bottom of the groove, and converge in the second space 12, and are further connected to the controller of the holographic fan 2.

[0065] In a more specific embodiment, the holographic fan controller includes a motor control board for controlling the starting and power supply of the motor of the holographic fan 2, and the motor control board is disposed in the second space 12.

[0066] In a more specific embodiment, the motor control board is disposed between two opposing U-shaped brackets 4. In some more specific embodiments, the motor control board is disposed in adjacent areas of the U-shaped brackets 4.

[0067] In a more specific embodiment, an electrical interface is provided at the bottom of the mounting groove 7, which is connected to a transmission wire located in the second space 12. The fan base 22 is provided with a power receiving protrusion corresponding to the electrical interface, which passes through the wire opening and connects to the electrical interface. It is understood that no additional wiring is required when installing the holographic fan 2, thus improving installation efficiency.

[0068] The installation sequence of a holographic fan advertising barrier in this embodiment is as follows:

[0069] S1. Insert the frame 81 into the barrier gate arm 1. Both sides of the protective frame 8 are fixed to the barrier gate arm 1 by L-shaped pieces 6.

[0070] S2. Fix the fan base 22 of the holographic fan 2 to the recess 41 of the U-shaped bracket 4;

[0071] S3. Embed the holographic fan 2 and the U-shaped bracket 4 together into the mounting groove 7 of the barrier arm 1, and fix the extension 42 of the U-shaped bracket 4 to the edge of the groove 7.

[0072] S4. Finally, press the display board 82 into the step of the frame 81 to fix it.

[0073] This embodiment provides a holographic fan advertising barrier gate, including a holographic fan advertising barrier gate arm 1 and a barrier gate machine 3. The barrier gate machine 3 is rotatably connected to one end of the barrier gate arm 1, and a control component for controlling the rotation of the barrier gate arm 1 is provided inside the barrier gate machine 3.

[0074] In a more specific embodiment, the barrier gate 3 is also equipped with a holographic fan control component for controlling the rotation, projection, and other operations of the holographic fan 2. The holographic fan 2 control component is electrically connected to the holographic fan 2. In some specific embodiments, the transmission wire of the second space 12 is connected to the holographic fan 2 control component. In other more specific embodiments, the holographic fan 2 control component is located at the end of the barrier gate arm 1.

[0075] In a more specific embodiment, the holographic fan 2 and protective frame 8 are positioned on the barrier arm 1 near the barrier gate 3. It can be understood that, from the perspective of the lever principle, the barrier arm 1 can be considered a lever, and the motor at the barrier gate acts as the fulcrum. When the weight of the holographic fan 2 and protective frame 8 is concentrated near the motor of the barrier gate 3, the lever arm is relatively short. According to the formula that torque equals the product of force and lever arm, with a fixed weight of the holographic fan 2 and protective frame 8, the shorter the lever arm, the smaller the torque. However, if the holographic fan 2 and protective frame 8 are positioned at the end far from the motor or in the middle of the barrier arm 1, the lever arm becomes longer, thus increasing the torque that the motor needs to overcome, and consequently increasing the load. Therefore, by positioning the holographic fan 2 and protective frame 8 on the barrier arm 1 near the barrier gate 3, the motor does not need to expend excessive energy to overcome the additional resistance caused by the large distance between the holographic fan 2 and protective frame 8 during startup and operation. This makes the motor run more smoothly, reduces problems such as overheating and damage caused by excessive load, and extends the service life of the motor.

[0076] In a more advanced embodiment, such as Figure 8 As shown, an extension fence 9 is installed at the end of the protective frame 8 away from the barrier gate 3, and the extension fence 9 is connected to the end of the barrier gate arm 1 away from the barrier gate 3. It is understood that, in specific implementations, this holographic fan advertising barrier gate will be applied to roads of varying widths. To avoid excessive load on the motor in the barrier gate 3, the holographic fan 2 and the protective frame 8 are installed on the barrier gate arm 1 near the barrier gate 3. To adapt the length of the barrier gate arm 1 to the road width, an extension fence 9 is installed at the end of the protective frame 8 away from the barrier gate 3, and the extension fence 9 is connected to the end of the barrier gate arm 1 away from the barrier gate 3, ensuring the interception effect.

[0077] In a more specific embodiment, the extended fence post 9 includes a horizontal bar and multiple vertical bars. One end of the horizontal bar is connected to the end of the barrier post 1, and the multiple vertical bars are arranged vertically and side by side on the horizontal bar, with the middle of the vertical bars connected to the horizontal bar.

[0078] In a more specific embodiment, the longitudinal bar and the transverse bar are rotatably connected, so that the angle between the longitudinal bar and the transverse bar is adjustable, which can better adapt to the running trajectory of the barrier arm 1.

[0079] It should be noted that the terms used to describe positional relationships in the above examples and accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. The various embodiments of this utility model described above are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
