Description

Technical Field

[0001] This utility model relates to the field of vehicle accessory design technology, and more specifically, to a vehicle sign bracket assembly and vehicle for dangerous goods. Background Technology

[0002] Dangerous goods vehicle signs (hereinafter referred to as signs) are signs that indicate the dangerous nature of the goods carried by the vehicle. They include three types: rectangular signs, diamond-shaped signs, and special signs. According to the "Road Transport Dangerous Goods Vehicle Signs" requirements, vehicles transporting dangerous goods should have a rectangular sign installed at the front of the vehicle. According to relevant regulations, the standard rectangular sign is 400mm long and 300mm high, with two fixing points along the upper edge. Because the front of the vehicle is typically curved, this sign cannot be directly installed and fixed at the front of the vehicle. A simple structure is used for fixing, resulting in poor connection strength. Utility Model Content

[0003] The main objective of this invention is to provide a vehicle sign bracket assembly and vehicle for dangerous goods, in order to solve the problem of vehicle signs being difficult to fix in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a vehicle sign holder assembly for dangerous goods is provided, comprising: a sign fixing plate, a first side of which forms a mounting surface for mounting a sign, the sign fixing plate having at least one connecting portion for connecting with the sign, and at least one limiting portion forming a limiting space for accommodating the sign; a connecting bracket, disposed on a second side of the sign fixing plate, a first end of which is connected to the sign fixing plate, and a second end of which forms a connecting end for connecting with a vehicle front panel; wherein, the first end of at least one connecting bracket and the second side of the sign fixing plate form a cavity, and a portion of the structure of at least one connecting portion is located within the cavity.

[0005] Furthermore, the connecting bracket includes: a bracket body, which is connected to the second side of the sign fixing plate, and the bracket body and the sign fixing plate form a cavity; and a connector, one end of which is connected to the bracket body, and the other end of which forms a connecting end.

[0006] Furthermore, the support body includes: two first connecting segments, which are arranged opposite each other, with the end of each first connecting segment facing the other first connecting segment being its inner end; two second connecting segments, which are arranged one-to-one with the two first connecting segments, with the first end of each second connecting segment connected to the inner end of the corresponding first connecting segment, and the second end of each second connecting segment extending away from the first connecting segment; and a third connecting segment, which is arranged parallel to the first connecting segments and located between the two second connecting segments, with the first end of the third connecting segment in the length direction connected to the second end of one of the second connecting segments, and the second end of the third connecting segment in the length direction connected to the second end of the other second connecting segment, so that the second connecting segments and the third connecting segment enclose a cavity, and a connector is connected to the third connecting segment.

[0007] Furthermore, the connecting part includes a connecting hole provided on the edge portion of the sign fixing plate.

[0008] Furthermore, the limiting part includes at least one limiting flange, one end of which is connected to the edge portion of the sign fixing plate, and the other end of which is folded toward the center of the sign fixing plate to form a limiting space.

[0009] Furthermore, the sign fixing plate is a polygonal structure, and the first end of the limiting flange is connected to one side of the polygonal structure. The length of the limiting flange is equal to that of the side. Alternatively, the first end of the limiting flange is connected to one side of the polygonal structure, the length of the limiting flange is less than that of the side, and there are multiple limiting flanges.

It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0031] Combination Figures 1 to 4 As shown in the specific embodiment of this application, a vehicle sign holder assembly for dangerous goods is provided.

[0032] The bracket assembly includes: a sign fixing plate 10, the first side of which forms a mounting surface for mounting a sign 11; the sign fixing plate 10 is provided with at least one connecting part 12 for connecting with the sign 11; and at least one limiting part 14 is provided on the sign fixing plate 10, forming a limiting space for accommodating the sign 11; a connecting bracket 31, which is disposed on the second side of the sign fixing plate 10; the first end of the connecting bracket 31 is connected to the sign fixing plate 10; and the second end of the connecting bracket 31 forms a connecting end for connecting with the front panel of a vehicle; wherein, the first end of at least one connecting bracket 31 and the second side of the sign fixing plate 10 form a cavity 100, and a portion of the structure of at least one connecting part 12 is located within the cavity 100.

[0033] By applying the technical solution of this utility model, the sign fixing plate 10 is fixed to the front bulkhead through the connecting bracket 31, which improves the connection strength of the sign and increases the overall rigidity of the bracket assembly. Through the support of the internal structure, the connection between the sign fixing plate 10 and the connecting bracket 31 is made more secure, reducing structural deformation or damage caused by vibration or external forces during vehicle operation. Furthermore, it effectively prevents the connection from being directly impacted by external forces during vehicle use, avoiding loosening of connecting bolts or nuts and ensuring the long-term stable fixing of the sign 11. This application solves the problem of insufficient connection strength of the bracket assembly in the prior art.

[0034] The cavity structure can provide a certain degree of dust and water protection, protecting the connection part 12 from the effects of harsh environments such as rain and dust, extending the service life of the connection part and maintaining its connection performance.

[0035] The cavity design can hide the connector 12 and some accessories, making the bracket assembly look cleaner and more beautiful, meeting the aesthetic requirements of modern vehicle design, while avoiding scratches or damage that may be caused by exposed parts.

[0036] By increasing the internal cavity, the direct contact between the sign 11 and the mounting plate can be reduced, thereby reducing the noise generated by the vibration of the sign when the vehicle is driving and providing a quieter driving environment.

[0037] Furthermore, the connecting bracket 31 includes: a bracket body 51, which is connected to the second side of the sign fixing plate 10, and the bracket body 51 and the sign fixing plate 10 surround to form a cavity 100; and a connector 52, one end of which is connected to the bracket body 51, and the other end of which forms a connecting end.

[0038] The cavity 100 is formed by the bracket body 51 and the sign fixing plate 10. This closed structure can significantly enhance the mechanical strength and rigidity of the entire bracket assembly and improve its ability to resist external impacts. Especially when driving at high speed, it can better ensure the stability of the sign.

[0039] Optionally, the space inside the cavity can act as a buffer zone to absorb the vibration energy transmitted to the sign, reduce the direct collision between the sign and the fixed plate, thereby reducing the shaking and noise of the sign during vehicle operation.

[0040] The cavity design improves airflow, reduces wind resistance in the signage area, making the vehicle more fuel-efficient at high speeds, while also reducing aerodynamic noise and improving driving comfort.

[0041] Alternatively, the cavity not only enhances the structural robustness but also provides space to conceal wiring or small sensors, facilitating the integration of vehicle monitoring systems or other additional functions without affecting the overall appearance.

[0042] Specifically, the cavity can effectively isolate water, dust and corrosive substances, protect the internal connectors 52 and other sensitive components, and extend their service life.

[0043] The two ends of the connector 52 are connected to the bracket body 51 and the vehicle front panel, respectively. This independent component design makes maintenance and replacement more convenient, allowing the position of the sign to be adjusted or the damaged connector to be replaced without disassembling the entire bracket assembly.

[0044] In an alternative embodiment, an adjustable mechanism between the bracket body 51 and the connector 52 allows the sign to be finely adjusted within a certain angle range, thus ensuring that the sign is always clearly visible while adapting to different vehicle shapes and regulatory requirements.

[0045] Optionally, the cavity contains a miniature motor or magnet to achieve intelligent locking and unlocking of the connection. It automatically locks when the sign needs to be fixed and can be released remotely or manually when it needs to be disassembled, improving the convenience and safety of use.

[0046] In an optional embodiment, by combining environmental sensors inside and outside the vehicle, such as wind speed sensors and road condition sensors, the built-in controller automatically adjusts the angle or fixing force of the sign to cope with different driving environments and ensure that the sign maintains its optimal condition under any circumstances.

[0047] In addition to serving as a protective cavity for the connection part, LED warning lights or RFID tags can be integrated into the cavity to further enhance the functionality and recognizability of the sign.

[0048] The support body 51 is made of lightweight, high-strength materials, such as carbon fiber composites or aluminum alloys, to make the support body 51 and connectors 52. This reduces weight while ensuring sufficient strength, making it especially suitable for large dangerous goods transport vehicles that require strict weight control.

[0049] The above design further enhances the intelligence and functionality of the support components, making it a comprehensive solution that integrates stability, intelligence, and multifunctionality, better serving the safety needs of the dangerous goods transportation industry.

[0050] Further, the support body 51 includes: two first connecting segments 511, which are arranged opposite each other, with the end of the first connecting segment 511 facing the other first connecting segment 511 being the inner end; and two second connecting segments 512, which are arranged one-to-one with the two first connecting segments 511, with the first end of each second connecting segment 512 connected to the inner end of the corresponding first connecting segment 511, and the second end of each second connecting segment 512 facing away from the first connecting segment 511. A connecting segment 511 extends in a certain direction; a third connecting segment 513 is arranged parallel to the first connecting segment 511 and is located between two second connecting segments 512. The first end of the third connecting segment 513 in the length direction is connected to the second end of one of the second connecting segments 512, and the second end of the third connecting segment 513 in the length direction is connected to the second end of the other second connecting segment 512, so that the second connecting segments 512 and the third connecting segment 513 enclose and form a cavity 100, and a connector 52 is connected to the third connecting segment 513.

[0051] The first connecting section 511, the second connecting section 512, and the third connecting section 513 together form a closed cavity structure. This triangular support design can significantly improve the structural stability of the support, making it more able to withstand the impact and pressure from the external environment.

[0052] Specifically, the formation of the cavity means that there are additional support points between the connecting bracket 31 and the sign fixing plate 10, which can effectively disperse the vibration generated during vehicle operation, reduce the displacement and shaking of the sign, thereby reducing noise and keeping the sign clearly visible.

[0053] The triangular structure and enclosed cavity can reduce wind resistance when the vehicle is in motion, improve airflow around the sign, and help improve fuel efficiency and reduce wind noise.

[0054] In fact, cavity 100 not only enhances the overall integrity of the bracket, but also provides an internal space that can be used to hide wiring, sensors or other small electronic devices, while protecting these components from damage by the external environment.

[0055] The connection design between the third connecting section 513 and the connector 52 simplifies the bracket assembly process. Simultaneously, the internal cavity design facilitates internal inspection and adjustment by maintenance personnel without requiring complete removal of the sign. This structural design results in a cleaner and more streamlined appearance for the bracket assembly, meeting the aesthetic requirements of modern vehicle design.

[0056] Optionally, the design of the first connecting section 511 and the second connecting section 512 includes adjustable hinges or telescopic mechanisms, allowing the entire bracket assembly to be angled according to the curved shape of the vehicle front panel and the visibility requirements of the sign, thereby achieving a more optimized sign installation position.

[0057] Furthermore, a miniature sensor and locking device are integrated inside the third connecting section 513. When the sign is installed in place, the connector 52 is automatically locked to ensure the stability of the sign. When the sign needs to be removed, it can be unlocked via wireless signal or vehicle control panel for easy and quick replacement.

[0058] Optionally, the first connecting segment 511, the second connecting segment 512, and the third connecting segment 513 are independent modules that are connected through standardized interfaces. This allows for flexible replacement and combination of modules according to the specific needs of different vehicle models or signs, thus achieving a wider range of applications.

[0059] Furthermore, LED light strips are integrated at appropriate locations within the cavity 100, which not only provide nighttime illumination for the sign and enhance visibility, but also flash different warning signals according to vehicle status (such as emergency braking, steering, etc.) to improve driving safety.

[0060] The technical solution adopted in this embodiment not only enhances the structural stability and functional versatility of the bracket body 51, but also improves its adaptability and intelligence level under different environmental conditions, providing a more comprehensive and innovative solution for fixing the signs of dangerous goods transport vehicles.

[0061] In an optional embodiment, the sign fixing plate has two welded nuts providing sign fixing points that meet regulatory requirements, and two snap-fit ​​points for auxiliary sign fixing; a connecting bracket is used for the transition connection between the sign fixing plate and the front end of the vehicle, and the connecting bracket has welded bolts for connection to the front end of the vehicle. The sign fixing plate and the connecting bracket are welded to form a bracket assembly, which is assembled on the front end of the vehicle to provide fixation for the dangerous goods vehicle sign. The dangerous goods vehicle sign fixing bracket, installed at the front end of the vehicle, solves the problem of the inability to directly fix the sign while meeting the requirements of the vehicle's front overhang and fixation.

[0062] Furthermore, the connecting part 12 includes a connecting hole 22 provided on the edge portion of the sign fixing plate 10.

[0063] Furthermore, the limiting part 14 includes at least one limiting flange 23, one end of which is connected to the edge portion of the sign fixing plate 10, and the other end of which is folded toward the center of the sign fixing plate 10 to form a limiting space.

[0064] The design of the limiting flange 23 can effectively limit the lateral and longitudinal displacement of the sign during vehicle movement, especially when encountering vibration or wind, ensuring that the sign is firmly fixed in the predetermined position and preventing the sign from affecting its recognizability due to displacement.

[0065] By folding to create a limiting space, the tiny gap between the sign and the fixing plate can be absorbed, reducing the contact and friction between the sign and the fixing structure, thereby reducing the shaking and abnormal noise of the sign under high-speed driving or bad road conditions.

[0066] The pre-formed limiting space of the limiting flange 23 makes it possible to install the sign without additional positioning tools. Simply align the sign with the limiting space and insert it to achieve quick positioning, which simplifies the installation and disassembly process of the sign and improves work efficiency.

[0067] The limit flange 23 wraps around the edge of the sign, protecting it from scratches and wear, extending its service life, and also preventing damage to the edges from environmental factors (such as corrosion) to some extent.

[0068] The limiting flange and the sign fixing plate are integrated into one design, reducing exposed fasteners and connectors and making the overall appearance of the bracket assembly more concise.

[0069] Optionally, the limiting part 14 includes an adjustable mechanism, such as a spring-loaded flange or a flange with a fine-tuning screw, which allows for adaptive adjustment of the limiting space according to signs of different thicknesses or sizes, ensuring the sign's secureness.

[0070] Optionally, a micro sensor can be integrated inside the limit flange 23 to detect whether the sign is correctly installed and fixed. If it is detected that it is not fixed or not installed correctly, a warning signal can be issued or the limit part can be automatically adjusted to the correct position.

[0071] Optionally, the limiting flange 23 can be made a detachable or replaceable component, so that when the size or type of the sign changes, the limiting part can be quickly replaced without replacing the entire bracket assembly, thus improving economy and practicality.

[0072] The limiting flange 23 includes an adaptive adjustment mechanism, such as a pneumatic or hydraulic system, which automatically adjusts the limiting space according to the pressure of the sign to ensure that the sign can be firmly fixed under different working conditions.

[0073] Optionally, a bracket for fixing the dangerous goods vehicle sign is provided. The bracket provides several fixing points, with screws securing the sign at the fixing points and two additional fixing points using snap-fit ​​connections to further secure the sign and prevent shaking or noise during vehicle operation. This application provides a bracket for fixing a dangerous goods vehicle sign, including a sign fixing plate and connecting brackets. The sign fixing plate and each connecting bracket are connected by welding. The difference between the connecting brackets is that they are different sizes to accommodate connection and fixation to the curved surface of the vehicle's front end. The sign fixing plate has two fixing holes along the upper edge of the front and welded nuts on the back for screw fixing to the upper part of the sign; the sign fixing plate also has two limiting flanges along the lower edge of the front for auxiliary fixing to the lower part of the sign. The connecting brackets are similar in appearance, all composed of brackets and welded bolts, but their main difference lies in their different sizes to accommodate connection and fixation to the curved surface of the vehicle's front end. The sign fixing plate, connecting bracket, connecting bracket, and connecting bracket are connected by welding to form a bracket assembly, which is installed at the front of the vehicle for fixing the sign of dangerous goods vehicles.

[0074] The bracket assembly is mounted on the front of the vehicle to secure the dangerous goods vehicle sign, ensuring the sign plate is installed vertically and does not extend beyond the front overhang. The sign plate mounting plate and the connecting brackets are welded together to form the bracket assembly, with at least three connecting brackets to ensure a secure fixation. The connecting brackets, equipped with welding bolts, provide a transition connection between the sign plate mounting plate and the front of the vehicle for connection to the front of the vehicle.

[0075] The snap-fit ​​fixing provided by the sign fixing plate is not limited to the two locations mentioned above. It can be a long slot along the bottom edge, or long slots on the left, right, and bottom edges, which can provide a more reliable fixation for the sign.

[0076] The number of connecting brackets at the rear of the sign holder is not limited to three, but to ensure the sturdiness and stability of the sign holder, the number should be no less than three.

[0077] The welded nuts mentioned in the sign fixing bracket can be replaced by rivet nuts; the welded bolts mentioned can also be replaced by welded nuts, rivet nuts, etc.; all the welding and other connection methods mentioned can also be replaced by other connection methods.

[0078] Furthermore, the sign fixing plate 10 is a polygonal structure, and the first end of the limiting flange 23 is connected to one side of the polygonal structure. The length of the limiting flange 23 is equal to that of the side. Alternatively, the first end of the limiting flange 23 is connected to one side of the polygonal structure, the length of the limiting flange 23 is less than that of the side, and there are multiple limiting flanges 23. The multiple limiting flanges 23 are spaced apart along the length direction of the side.

[0079] Furthermore, the sign fixing plate 10 is provided with multiple weight-reducing cavities.

[0080] Furthermore, at least two weight-reducing cavities are spaced apart along the height direction of the sign fixing plate 10, and at least one connecting bracket 31 is disposed between the two weight-reducing cavities spaced apart along the height direction of the sign fixing plate 10.

[0081] By incorporating a weight-reducing cavity into the sign fixing plate 10, the weight of the entire support assembly can be significantly reduced. This is particularly important for transport vehicles, as weight reduction improves fuel efficiency, reduces energy consumption, and also helps lower overall vehicle maintenance costs. Although some materials are reduced, careful design of the layout and dimensions of the weight-reducing cavity ensures that the structural strength of the sign fixing plate 10 is not compromised. Furthermore, internal reinforcing ribs within the cavity enhance its bending and torsional resistance, ensuring the stability of the sign under various road conditions.

[0082] The weight-reducing cavity design can also improve airflow around the sign and mounting plate, reducing drag. Especially for high-speed vehicles, it can reduce wind resistance, further improve fuel efficiency, and reduce noise.

[0083] The weight-reducing cavity can serve as a space to hide wiring and install small sensors or LED lights, maintaining a clean appearance while increasing functionality and safety.

[0084] Optionally, an adjustable vent can be integrated into the weight reduction chamber to automatically adjust the ventilation volume according to the vehicle speed and the ambient temperature, which can ensure the lightweight of the support structure and effectively manage the temperature and airflow in the sign area.

[0085] Furthermore, the connecting end of the connecting bracket 31 is a quick-connect structure. The quick-connect structure has a working position for clamping the connecting bracket 31 onto the mating part on the front bulkhead, and a working position for releasing the connecting bracket 31 from the mating part.

[0086] According to another aspect of the present invention, a vehicle is provided, including a bracket assembly, which is the bracket assembly described above.

[0087] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0088] The bracket assembly described in this application solves the problem that dangerous goods vehicle signs cannot be directly fixed to the front of the vehicle, ensuring that the installation of the signs complies with regulatory requirements.

[0089] The snap-fit ​​structure added in this application effectively prevents the sign from shaking and making abnormal noises during vehicle operation, and improves the sign's fixation reliability.
