Technical Field

[0001] The utility model relates to the field of antenna brackets, in particular to an antenna bracket for an unmanned driving cab. Background Art

[0002] With the continuous improvement of the safety performance and intelligence level of off-highway dump trucks, more and more off-highway dump trucks are equipped with various intelligent devices; therefore, the unmanned driving cab of the off-highway dump truck needs to install accessories such as LiDAR, antennas, and cameras supporting the intelligent devices on the antenna bracket at the top outside the driving cab.

[0003] In the prior art, the Chinese utility model patent with the authorized publication number CN 219998474 U discloses an antenna bracket for an unmanned driving cab of an off-highway dump truck, which comprises a bracket body; the bracket body is fixedly arranged at the top outside the driving cab; the bracket body is provided with a plurality of GNSS antenna mounting brackets, a plurality of camera mounting brackets and a LiDAR mounting bracket; the bracket body comprises vertical beams, transverse beams and longitudinal beams, and the vertical beams, the transverse beams and the longitudinal beams are fixedly connected by welding; the transverse beams are arranged between the longitudinal beams; the vertical beams are arranged at the upper ends of the longitudinal beams; the transverse beams and the longitudinal beams are respectively provided with extended mounting holes.

[0004] When adopting the above technical solution, the vertical beams, transverse beams and longitudinal beams of the bracket body are fixedly connected by welding. However, due to the poor road quality in open-pit mining areas and the frequent scattering of coal blocks on the road surface, the dump truck experiences severe jolts during unmanned driving, making the antenna bracket operate under high-frequency and high-impact vibration conditions. The bracket with a welded structure has insufficient strength, especially at the weld seams, where cracking failure often occurs, thus affecting the overall accuracy and stability of the antenna bracket. Contents of the Utility Model

[0005] In order to solve the above technical problem of insufficient strength of the antenna bracket in the prior art, the utility model provides an antenna bracket for an unmanned driving cab, which has higher strength and is more suitable for the high-frequency and high-impact vibration working conditions of unmanned dump trucks.

[0006] The technical solution adopted by the utility model to solve the above technical problem is an antenna bracket for an unmanned driving cab, comprising a bracket body, wherein the bracket body is a bent structure, the bracket body comprises a horizontally arranged first mounting part, two ends of the first mounting part are vertically and downwardly provided with second mounting parts, the end of each second mounting part is horizontally connected with a support part, the support parts are perpendicular to the first mounting part, and the support parts are used for connecting with the top of the driving cab.

[0007] This utility model uses a bracket body with an integrated bending structure, which, compared with the prior art, avoids thermal deformation caused by welding, ensures the consistency of the overall size of the bracket, provides a reliable foundation for the precise positioning of the unmanned antenna, and has stronger vibration resistance and fatigue performance. At the same time, the integrated bending structure eliminates the need for multiple processes such as cutting, grinding, and painting required by welding, reducing the manpower input and time cost in the production process and reducing material waste.

[0008] Furthermore, the support body is made of a bent round tube.

[0009] This invention achieves a lightweight design by using tubing to manufacture the support.

[0010] Furthermore, a support diagonal rod is provided between the support part and the second mounting part.

[0011] This invention disperses stress by setting up supporting diagonal braces, reduces stress concentration points, and is better able to resist structural fatigue caused by long-term vibration, making it more suitable for the frequent bumps and impacts encountered during the operation of dump trucks.

[0012] Furthermore, the mounting part 1 is provided with at least two mounting plates 1. The mounting plates 1 have an L-shaped structure. The horizontal part of the mounting plate 1 is located at the upper part of the mounting part 1. The vertical part of the mounting plate 1 is connected to the mounting part 1 through a connector 1. The connector 1 has a U-shaped structure. The connector 1 extends out of the vertical part around the mounting part 1. A locking nut 1 is provided at the end of the connector 1 that extends out of the vertical part.

[0013] This utility model can conveniently connect the mounting plate and the mounting part through the U-shaped connector, thereby improving installation and maintenance efficiency.

[0014] Furthermore, a pad is provided between the vertical part and the mounting part one. The end of the pad one near the mounting part one is provided with an arc-shaped groove. The arc-shaped groove is in contact with the circumferential surface of the mounting part one. The end face of the pad one away from the mounting part one is in contact with the vertical part. The connector one passes through the pad one.

[0015] This invention increases the contact area between the pad and the mounting part by using a pad with an arc-shaped groove, thereby increasing the friction between the pad and the mounting part and preventing the mounting plate from rotating around the mounting part.

[0016] Furthermore, the pad is made of rubber.

[0017] This invention uses a rubber pad that absorbs vibration, thereby reducing vibration at the transmission antenna.

[0018] Furthermore, a second mounting plate is provided on the second mounting part, and the second mounting plate is provided on the outer side of the second mounting part via a second connector. The second connector has the same structure as the first connector. A stop block is also provided on the outer side of the second mounting part, and the stop block can abut against the lower end face of the second mounting plate.

[0019] This invention, by setting a stop, can prevent the second mounting plate from sliding down the second mounting part under the action of vibration and its own gravity, thereby improving the reliability of the positioning of the second mounting plate.

[0020] Furthermore, one of the mounting parts two is also provided with a mounting plate three, which is located at the lower part of the mounting plate two. The mounting plate three is provided with a sub-support, which has an L-shaped structure. The top of the sub-support is provided with a mounting plate four through a connector four. A support plate is vertically provided on the mounting plate four, which is used to support the corresponding antenna.

[0021] This invention enhances the support strength for longer antennas by providing a support plate, preventing damage to longer antennas under vibration.

[0022] Furthermore, a support rod is horizontally provided between the mounting plate three on the corresponding side and the sub-bracket.

[0023] This invention enhances the support strength of the secondary support by setting a support rod, thereby greatly reducing the shaking of the secondary support under external force.

[0024] Furthermore, the lower part of the support is provided with a mounting base, which has an L-shaped structure. The horizontal part of the mounting base is provided with mounting holes, and a reinforcing plate is also vertically provided on the mounting base. The reinforcing plate is connected to the second mounting part and the support part respectively.

[0025] This utility model facilitates the connection between the bracket body and the vehicle roof by setting a mounting base, and the addition of a reinforcing plate can further enhance the strength of the bracket body and greatly prevent deformation.

[0026] As can be seen from the above technical solutions, this utility model has the following advantages: This utility model provides an antenna bracket for an unmanned driving cab. By using a bent-integrated bracket body, compared to existing technologies, it avoids thermal deformation caused by welding, ensuring the consistency of the overall bracket dimensions and providing a reliable foundation for precise positioning of the unmanned driving antenna. It also offers stronger vibration and fatigue resistance. Furthermore, the bent-integrated design eliminates the need for multiple processes such as cutting, grinding, and painting required for welding, reducing manpower and time costs in the production process and minimizing material waste. The use of tubular materials in the bracket manufacturing process achieves a lightweight design. The inclusion of support diagonal braces to distribute stress reduces stress concentration points, making the bracket body more resistant to structural fatigue caused by long-term vibration, and more suitable for the frequent bumps and impacts encountered during dump truck operation. A U-shaped connector facilitates the connection between the mounting plate and the mounting section, improving installation and maintenance. The system improves protection efficiency by using a pad with an arc-shaped groove to increase the contact area between the pad and the mounting part, thereby increasing friction and preventing the mounting plate from rotating around the mounting part. The rubber pad absorbs vibration, reducing vibration at the antenna location. A stop block prevents the mounting plate from sliding down the mounting part under vibration and its own weight, improving the reliability of its positioning. A support plate enhances the support strength for longer antennas, preventing damage from vibration. A support rod strengthens the support for the sub-support, significantly reducing vibration under external forces. A mounting base facilitates connection between the support body and the roof, and a reinforcing plate further enhances the strength of the support body, greatly preventing deformation.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

The end of the mounting part 102 is horizontally connected to a support part 103. The support part 103 is perpendicular to the mounting part 101 and is used to connect to the top of the cab.

[0035] This specific embodiment uses a bracket body 1 with an integrated bending structure, which avoids thermal deformation caused by welding compared to the prior art, ensures the consistency of the overall size of the bracket, provides a reliable foundation for the precise positioning of the unmanned antenna, and has stronger vibration resistance and fatigue performance. At the same time, the integrated bending structure eliminates the need for multiple processes such as cutting, grinding, and painting required by welding, reducing the manpower input and time cost in the production process and reducing material waste.

[0036] Preferably, the support body 1 is made of a round tube bent into shape, which enables a lightweight design.

[0037] like Figure 1 and Figure 2As shown, to further enhance strength, in this specific embodiment, a support diagonal rod 104 is provided between the support part 103 and the mounting part 2 102. Specifically, the two ends of the support diagonal rod 104 are welded to the support part 103 and the mounting part 2 102.

The end of the pad 17 near the mounting part 101 has an arc-shaped groove 14, which is in contact with the circumferential surface of the mounting part 101. The end face of the pad 17 away from the mounting part 101 is in contact with the vertical part of the mounting plate 2. The connector 9 passes through the pad 17. To absorb energy and reduce vibration transmission, the pad 17 is made of rubber. In this specific embodiment, there are two mounting plates 2, which are used to install different antennas.

[0039] like Figure 1 and Figure 2 As shown, in this specific embodiment, a mounting plate 3 is provided on the mounting part 2 102. The mounting plate 3 has an L-shaped structure.

Furthermore, since the mounting plate 3 is set on the vertically set mounting part 2 102, in order to prevent the mounting plate 3 from sliding down under vibration and external force, in this specific embodiment, a stop block 15 is also welded to the outside of the mounting part 2 102. The stop block 15 can abut against the lower end face of the mounting plate 2 3, effectively preventing the mounting plate 2 3 from sliding down.

[0040] like Figure 1 and Figure 2As shown, in a preferred embodiment, one of the mounting parts 2 102 is further provided with a mounting plate 3 13. The mounting plate 3 13 is located below the mounting plate 2 3. The mounting plate 3 13 has a flat plate structure.

The sub-support 4 has an L-shaped structure. The top of the sub-support 4 is provided with a mounting plate 4 5 through a connector 4 11 and a pad 4. The structure of the connector 4 11 is the same as that of the connector 1 9, and will not be described again. The structure of the pad 4 is the same as that of the pad 1 17, and will not be described again. A support plate 6 is vertically mounted on the mounting plate 4 5. The support plate 6 is used to support the corresponding antenna. To enhance the support strength of the sub-support 4, a support rod 12 is horizontally mounted between the mounting plate 3 13 on the corresponding side and the sub-support 4. The two ends of the support rod 12 are welded to the vertical part of the mounting plate 2 3 and the sub-support 4, respectively. Specifically, the support plate 6 includes an L-shaped plate, which includes a horizontal part and a vertical part. A connecting plate is vertically mounted on the horizontal part. The connecting plate is connected to the sub-support 4 through a pad 4 and a pad 17. The vertical part is provided with mounting holes for mounting the antenna. The support plate 6 has a trapezoidal structure, and its wide end is connected to the upper end of the vertical part. The support plate 6 and the L-shaped plate are an integrated structure.

[0043] In this specific embodiment, all welds are subjected to ultrasonic impact or heat treatment to remove welding stress and enhance welding strength.

[0044] As can be seen from the above specific embodiments, this utility model has the following beneficial effects: 1. By using the integrated bending structure of the bracket body 1, compared with existing technologies, thermal deformation caused by welding is avoided, ensuring the consistency of the overall dimensions of the bracket, providing a reliable foundation for the precise positioning of the unmanned antenna, and exhibiting stronger vibration resistance and fatigue performance. At the same time, the integrated bending structure eliminates the need for multiple processes such as cutting, grinding, and painting required by welding, reducing manpower and time costs in the production process and reducing material waste; the use of tubular materials to manufacture the bracket achieves a lightweight design. 2. By setting up support diagonal braces 104 to disperse stress and reduce stress concentration points, the main body can better resist structural fatigue caused by long-term vibration, making it more suitable for the frequent bumps and impacts during the driving process of dump trucks. 3. The mounting plate 2 and the mounting part 101 are easily connected by the U-shaped connector, which improves the efficiency of installation and maintenance. By using the pad 17 with the arc groove 14, the contact area between the pad 17 and the mounting part 101 can be increased, the friction between the pad and the mounting part 101 can be increased, and the mounting plate 2 can be prevented from rotating around the mounting part 101. 4. By using a rubber pad-17, vibration can be absorbed, thus reducing vibration at the transmission antenna. 5. By setting the stop block 15, the mounting plate 2 3 can be prevented from sliding down the mounting part 2 102 under the action of vibration and its own gravity, thereby improving the reliability of the positioning of the mounting plate 2 3. 6. By setting the support plate 6, the support strength for longer antennas can be enhanced, preventing longer antennas from being damaged under vibration. 7. By setting support rod 12, the support strength of the sub-support 4 is enhanced, which greatly reduces the shaking of the sub-support 4 under the action of external force; 8.
