[0049] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0050] Because unmanned transport vehicles (UGVs) operate on autonomous driving systems, magnetic nail sensors and power supply modules are integrated at the front and rear of the vehicle to ensure the accuracy of their transport routes. Existing UGVs use brackets to integrate these functional devices, but these brackets, being steel structures, require welding and sheet metal bending, resulting in a complex and inefficient production process and increased overall weight, reducing the UGV's load capacity. For UGVs used in ports, multiple painting processes are required for corrosion prevention, further increasing production costs. During assembly, the brackets are prone to rubbing against the UGV's exterior, causing paint peeling and subsequent rusting. Furthermore, existing brackets can only integrate a limited number of functional devices, limiting their full potential and overall functionality.

[0051] Based on this, please refer to Figures 1-6 A multifunctional bracket assembly is provided. The bracket assembly 1 is detachably connected to the vehicle frame 2. The bracket assembly 1 includes a bracket body 11, an anti-collision mechanism 12, and a support component 13 for mounting a magnetic nail antenna. In the height direction of the bracket body 11, the support component 13 is detachably connected to the lower end of the bracket body 11. The anti-collision mechanism 12 is detachably connected to one side of the bracket body 11 in the length direction, and the distance between the anti-collision mechanism 12 and the bracket body 11 is adjustable.

[0052] It is understood that by connecting the support component 13 and the anti-collision mechanism 12 to the bracket body 11, the present invention integrates anti-collision and magnetic induction functions into one unit, thereby improving the functionality of the bracket body 11. Furthermore, the support component 13 and the anti-collision mechanism 12 are detachably connected to the bracket body 11, simplifying the structure of the bracket assembly 1 and reducing assembly difficulty.

[0053] In some embodiments, the support assembly 13 includes at least two crossbeams 131 and at least two longitudinal beams 132; the crossbeams 131 and longitudinal beams 132 are connected perpendicularly to each other and enclose at least one assembly space. Preferably, two crossbeams 131 and two longitudinal beams 132 are provided respectively, and the two crossbeams 131 are arranged opposite each other, and the two longitudinal beams 132 are arranged opposite each other, enclosing a rectangular assembly space for supporting the magnetic nail antenna. The formation of the assembly space can improve the connection stability between the magnetic nail antenna and the support body 11.

[0054] In some embodiments, the support body 11 includes at least two opposing first legs 111, at least two opposing second legs 112, and at least two opposing diagonal braces 113; the first legs 111 and second legs 112 are parallel to each other and spaced apart; the support assembly 13 is connected to the first legs 111 and the second legs 112 respectively; one end of the diagonal brace 113 is connected to the second leg 112, and the other end of the diagonal brace 113 is used to connect to the frame 2; the diagonal brace 113 is inclined relative to the length direction of the second leg 112, and the other end of the diagonal brace 113 is inclined towards the first leg 111. Preferably, there are two of each of the first legs 111, second legs 112, and diagonal braces 113. The first legs 111, second legs 112, and diagonal braces 113 are separately arranged, and their upper ends are respectively connected to the frame 2, which simplifies the structure compared to existing supports. Preferably, the first leg 111, the second leg 112, and the diagonal brace 113 are made of aluminum profiles, which reduces the overall weight compared to a steel bracket and eliminates the need for welding, significantly reducing manufacturing difficulty. Furthermore, each second leg 112 is equipped with a fixing frame 14 and a trailer hook 15 to improve the functionality of the bracket assembly 1.

[0055] In some embodiments, one end of the support component 13 is connected to the lower end of the first leg 111, and the other end of the support component 13 is connected to the side wall of the second leg 112; the support component 13 is perpendicular to the first leg 111 and the second leg 112 respectively, so that the second leg 112 blocks the support component 13 and the magnetic nail antenna mounted on the support component 13.

[0056] In some embodiments, the length of the second leg 112 is greater than that of the first leg 111. The second leg 112 is located near the end of the frame 2 along the length of the frame 2. Therefore, the length of the second leg 112 is greater than that of the first leg 111, which can block the support assembly 13 during vehicle operation and reduce the stress on the support assembly 13 in the length of the frame 2.

[0057] In some embodiments, the anti-collision mechanism 12 includes a bumper assembly 121, a first buffer member 122, a limiting component 123, and a sensing component 124. The bumper assembly 121 and the limiting component 123 are movably connected relative to each other. The first buffer member 122 is sleeved on one end of the bumper assembly 121 and located within the limiting component 123. When the bumper assembly 121 moves relative to the limiting component 123, the first buffer member 122 is compressed or released. The fixed end of the sensing component 124 is connected to the limiting component 123, and the sensing end of the sensing component 124 is opposite to the trigger end of the bumper assembly 121. Preferably, the first buffer member 122 is a compression spring. When the bumper assembly 121 is impacted, it will move relative to the limiting component 123 and compress the first buffer member 122. Therefore, the first buffer member 122 plays a buffering role in this process, preventing the bumper body 1211 from directly colliding with the bracket body 11. The sensor component 124 is configured to detect changes in the bumper assembly 121. Upon receiving the signal from the sensor component 124, the PLC controller executes an emergency braking action on the unmanned transport vehicle, promptly stopping it and minimizing potential losses. Specifically, a set of first buffer components 122, limit components 123, and sensor components 124 are respectively installed on the two opposing second legs 112. Both ends of the bumper assembly 121 are connected to the corresponding limit components 123.

[0058] In some embodiments, the bumper assembly 121 includes a bumper body 1211, a transmission rod 1212, and a trigger 1213; one end of the transmission rod 1212 is connected to the bumper body 1211, and the other end of the transmission rod 1212 passes through the limiting assembly 123 and is connected to the trigger 1213; a portion of the trigger 1213 is disposed opposite to the sensing end of the sensing assembly 124. Preferably, in the length direction of the frame 2, there is a gap between the bumper body 1211 and the second support leg 112, and in the width direction of the support body 11, the bumper body 1211 is disposed across the support body 11 to protect the support body 11.

[0059] In some embodiments, a limiting member 1214 is sleeved on the transmission rod 1212; the limiting member 1214 is located inside the limiting assembly 123 and abuts against the end of the first buffer member 122 away from the trigger member 1213. The limiting member 1214 is provided to push the first buffer member 122 to compress after the bumper body 1211 is impacted, thereby buffering the bumper body 1211 and preventing the bumper body 1211 from directly impacting the bracket body 11.

[0060] In some embodiments, the sensing component 124 includes a sensing bracket 1241 and a sensor 1242. The sensing bracket 1241 is connected to the limiting component 123, and the sensor 1242 is disposed on the sensing bracket 1241, with the sensing end of the sensor 1242 opposite to the trigger 1213 of the bumper assembly 121. Preferably, the sensor 1242 is a proximity switch. The relative position of the sensor 1242 and the limiting component 123 is maintained by the sensing bracket 1241, thereby enabling timely detection of position changes in the bumper assembly 121 and ensuring reliability.

[0061] In some embodiments, the limiting assembly 123 includes a sleeve 1231, a second buffer member 1232, and two opposing limiting brackets 1233. The sleeve 1231 is located between the two limiting brackets 1233, and both the first buffer member 122 and the limiting member 1214 are embedded within the sleeve 1231. The second buffer member 1232 is sleeved outside the sleeve 1231. By providing the sleeve 1231 and the limiting brackets 1233, an active space is formed within the sleeve 1231 for the first buffer member 122 to compress or release, ensuring that the bumper assembly 121 has sufficient buffer space. The second buffer member 1232 is provided to support the limiting brackets 1233.

Specifically, a set of first buffers 122, limiting components 123, and sensing components 124 are respectively installed on the two oppositely arranged second legs 112, and the two ends of the bumper assembly 121 are respectively connected to the corresponding limiting components 123.

[0068] In this embodiment, the bumper assembly 121 includes a bumper body 1211, a transmission rod 1212, and a trigger 1213. One end of the transmission rod 1212 is connected to the bumper body 1211, and the other end of the transmission rod 1212 passes through the limiting component 123 and is connected to the trigger 1213.
