[0034] This utility model embodiment provides an AGV anti-collision buffer device, including:
[0035] The main body of the anti-collision beam 10 is equipped with a buffer damping rod 20 and a Hall sensor at its front end;
[0036] The anti-collision beam 30 is connected to the buffer damping rod 20 through the connecting bracket 40. There is a gap between the anti-collision beam 30 and the detection end of the Hall sensor, and a magnet 31 is provided at the position corresponding to the Hall sensor.
[0037] When a collision occurs, the connecting bracket 40 causes the anti-collision beam 30 to shift relative to the anti-collision beam body 10.
[0038] In specific implementation, such as Figures 1-6 As shown, the AGV anti-collision buffer device includes:
[0039] The main body 10 of the anti-collision beam is equipped with a buffer damping rod 20 and a Hall sensor facing the direction of vehicle travel at its front end. The buffer damping rod 20 includes, but is not limited to, a gas strut, a hydraulic damping rod, an electric push rod, etc.; the Hall sensor is electrically or communicatively connected to the vehicle control module.
[0040] The anti-collision beam 30 has rearwardly inclined side walls on both sides, and is connected to the connecting bracket 40 (e.g., Figure 5 (As shown) is connected to the buffer damping rod 20, and there is a gap between the anti-collision beam 30 and the detection end of the Hall sensor, and a magnet 31 is provided at the position corresponding to the Hall sensor;
[0041] In the event of a collision, the connecting bracket 40 causes the anti-collision beam 30 to shift relative to the anti-collision beam body 10. Specifically, in implementation, such as... Figure 5 , Figure 6 As shown, the connecting bracket 40 includes connecting plates 41 and a fastening shaft 42; two connecting plates 41 are disposed opposite each other on the side wall of the anti-collision beam 30; the vertical distance between the two connecting plates 41 is adapted to the end of the buffer damping rod 20, and the end of the buffer damping rod 20 is located between the two connecting plates 41; the fastening shaft 42 passes vertically through the connecting plates 41 and the buffer damping rod 20, connecting and fixing the anti-collision beam 30 and the buffer damping rod 20. The fastening shaft 42 includes, but is not limited to, a bolt structure. The tightness of the connection between the anti-collision beam 30 and the buffer damping rod 20 can be adjusted by adjusting the tightness of the bolts, so that it will not move when the vehicle is driving normally, but the anti-collision beam 30 will generate displacement relative to the anti-collision beam body 10 when a collision occurs. This tightness adjustment is determined by the engineer based on experience or test results, and will not be described in detail here.
[0042] Working principle: The buffer damping rod 20 is connected to the anti-collision beam 30 through the connecting bracket 40. When a collision occurs, whether it is a frontal or side collision, the distance between the magnet and the Hall sensor will change. The Hall sensor detects the change in magnetic field, thereby detecting that a collision has occurred. The Hall sensor sends the detected signal to the vehicle's control device. After receiving the signal, the control device triggers emergency braking to stop the vehicle.
[0043] In practice, the anti-collision beam 30 is tilted towards one side of the vehicle on both sides.
[0044] The AGV anti-collision buffer device provided in this embodiment of the utility model achieves anti-collision protection for AGV vehicles through a structure combining an anti-collision beam body, a buffer damping rod, a Hall sensor, a magnet, and an anti-collision crossbeam. Furthermore, the structure is simple and the production cost is low.
[0045] Furthermore, the main body 10 of the anti-collision beam is connected to the buffer damping rod 20 and the Hall sensor via a fixed bracket 50; the fixed bracket 50 is detachably connected to the main body 10 of the anti-collision beam.
[0046] In specific implementation, such as Figure 1 As shown, the main body 10 of the anti-collision beam is connected to the buffer damping rod 20 and the Hall sensor via a fixed bracket 50. The fixed bracket 50 is detachably connected to the main body 10 of the anti-collision beam, and the detachable connection structure includes, but is not limited to, bolt connections, snap-fit structures, etc. The detachable fixed bracket 50 allows the sensor, damping rod, and even the entire fixed bracket module to be replaced, repaired, or calibrated independently and conveniently without disassembling the entire anti-collision beam, simplifying the maintenance process and reducing maintenance costs and time.
[0047] In specific implementation, such as Figure 2 As shown, the fixed bracket 50 includes a connecting plate 51 and a mounting chamber 52;
[0048] The connecting plate 51 is provided with a first through hole 511 and a second through hole ( Figure 2 The first through hole 511 is used for bolting to the main body 10 of the anti-collision beam, and the second through hole is used for installing the buffer damping rod 20. The design of the first through hole 511 and the second through hole ensures the precise positioning and reliable connection of the anti-collision beam main body 10 and the buffer damping rod 20 on the fixed bracket.
[0049] The mounting chamber 52 is located on one side of the connecting plate 51 and is used to mount the Hall sensor. The mounting chamber 52 can protect the Hall sensor, and the independent mounting chamber 52 provides physical protection and possible electromagnetic shielding for the Hall sensor, thereby improving the reliability and stability of the sensor.
[0050] In specific implementation, such as Figure 3As shown, the fixed bracket 50 also includes a clamping plate 53; the clamping plate 53 has a third through hole 531 at the part corresponding to part of the first through hole 511, and a notch 532 at the part corresponding to the second through hole; the clamping plate 53 is bolted to the first through hole 511 through the third through hole 531. This connection structure, by sharing the first through hole 511, can reduce the fixing structure of a buffer damping rod 20, thereby saving parts costs and making the whole more compact. In this embodiment, the added clamping plate 53 adds a "wasp" or "pressure plate" at the bolt connection, which significantly improves the rigidity and stability of the connection part and effectively prevents the bolt from loosening, especially in the AGV environment subjected to vibration and impact.
[0051] In specific implementation, such as Figure 3 As shown, the third through hole 531 is an elongated through hole with its length arranged horizontally. The elongated through hole can accommodate the installation of the first through hole 511 at different horizontal positions, providing installation adjustment margin.
[0052] In specific implementation, such as Figure 2 As shown, a baffle (not marked in the figure) is provided on the side of the mounting chamber 52, and the baffle is bolted to the mounting chamber 52; a fourth through hole 521 is provided at the front end of the mounting chamber 52, which is the detection window of the Hall sensor; the Hall sensor can be easily maintained through the detachable side of the mounting chamber 52, so that the Hall sensor can be inspected, replaced or calibrated directly by opening the side of the mounting chamber without disassembling the entire fixed bracket 50 or even without disassembling the anti-collision beam body 10; this greatly simplifies the maintenance operation of the sensor and reduces the maintenance difficulty and time cost.
[0053] In specific implementation, such as Figure 1 As shown, the main body 10 of the anti-collision beam includes a mounting part 11, a vertical extension part 12, and a horizontal extension part 13. The mounting part 11 has several through holes for bolt connection with the vehicle. The vertical extension part 12 is located below the mounting part 11. The horizontal extension part 13 is connected to the mounting part 11 through the vertical extension part 12. The anti-collision beam main body 10 structure provided in this embodiment clearly distinguishes the functional areas: the mounting part is responsible for connecting with the vehicle body, the horizontal extension part carries the front buffer / sensing module (fixed bracket, etc.), and the vertical extension part serves as a support connection. This design is beneficial for optimizing material distribution, reducing weight, and improving overall rigidity and bending / torsional resistance. It is also more adaptable to the spatial layout and installation interface requirements of different vehicle chassis.
[0054] Furthermore, a reinforcing rod is provided between the vertical extension 12 and the horizontal extension 13 and / or the mounting portion 11.
[0055] In specific implementation, such as Figure 4As shown, the vertical extension 12 and the horizontal extension 13 are provided with a first reinforcing rod 14; a second reinforcing rod 15 is provided between the vertical extension 12 and the mounting part 11; by adding reinforcing rods between the vertical extension 12 and the horizontal extension 13 and / or the mounting part 11, stress concentration points or weak connection areas in the structure (especially L-shaped corners) are specifically strengthened, effectively improving the structural strength and rigidity of the anti-collision beam body during collision or load-bearing, and preventing deformation or breakage.
[0056] Furthermore, the vertical extension 12 is provided with a traction structure 121. The traction structure 121 in the vertical extension 12 enables the anti-collision buffer device to not only have an anti-collision function but also integrate a traction hook or connection point. This eliminates the need to install a separate traction device in other parts of the vehicle, improves the vehicle's functional integration and space utilization, and facilitates AGV towing operations.
[0057] This utility model also provides a vehicle that uses any of the AGV anti-collision buffer devices described above.
[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
