DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The utility model provides a double-station RGV trolley, such as Figure 1 and Figure 2 As shown, it includes a vehicle body 1, a load-bearing plate 2, an anti-collision mechanism 3 and an anti-collision side strip 4. Two sets of load-bearing plates 2 for supporting articles are installed on the upper end of the vehicle body 1. The anti-collision mechanism 3 is arranged at both ends of the vehicle body 1, and the anti-collision side strip 4 is fixed on both sides of the vehicle body 1. The anti-collision mechanism 3 includes a mounting plate 31, a buffer 32 and a locking member 33. The mounting plate 31 is fixed on the vehicle body 1. A slide groove 311 is provided inside the mounting plate 31. A connecting column 312 is provided on one side of the slide groove 311. One end of the connecting column 312 is fixedly connected to a limited position head 313. A buffer 32 is provided on one side of the mounting plate 31. The buffer 32 includes a telescopic member 321 and a locking member 33. The impact plate 322, multiple sets of telescopic parts 321 are fixed at both ends of the mounting plate 31, the impact plate 322 is fixed at one end of the multiple sets of telescopic parts 321, the telescopic parts 321 include an outer cylinder 3211, a slide bar 3212 and a spring 3213, the outer cylinder 3211 is fixed on the mounting plate 31, the slide bar 3212 is slidably connected inside the outer cylinder 3211, the spring 3213 is sleeved on the outside of the slide bar 3212, and the slide bar 3212 and the impact plate 322 are fixedly connected. The double-station RGV trolley usually runs along a straight line or a predetermined path, which means that the front and rear ends are more easily exposed to areas where collisions may occur, while the two sides are relatively less at risk of being hit, so anti-collision mechanisms 3 are installed at the front and rear ends for better protection. When the two sides of the double-station RGV trolley are hit, they will hit the anti-collision side strips 4 to cause them to deform and absorb energy, thereby reducing the impact force on the double-station RGV trolley. When the front and rear ends are hit, they will hit the impact plate 322, causing the impact plate 322 to squeeze the telescopic member 321, and the slide rod 3212 slides toward the inside of the outer cylinder 3211, while compressing the spring 3213 to buffer the impact on the double-station RGV trolley.
[0027] like Figure 3 and Figure 4As shown, a locking member 33 is provided on the inner side of the striking plate 322, and the locking member 33 includes a support rod 331, a connecting rod 332 and a sliding block 333. The support rod 331 is fixed on the striking plate 322, and one end of the support rod 331 is rotatably connected to multiple connecting rods 332, and one end of multiple connecting rods 332 is rotatably connected to the sliding block 333. The sliding block 333 is slidably connected to the inside of the slide groove 311, and one side of the sliding block 333 is fixedly connected to an opening member 3331, and a through hole is opened at the center position of the opening member 3331. The limiting head 313 passes through the through hole on the opening member 3331. The limiting head 313 is truncated cone-shaped, and the size of the maximum end face of the limiting head 313 is larger than the size of the through hole on the opening member 3331. Figure 5 As shown, a fixing screw 314 is provided through the interior of the limiting head 313 , and the fixing screw 314 detachably fixes the limiting head 313 and the connecting column 312 on the mounting plate 31 . The backward movement of the impact plate 322 will cause the support rod 331 to move backward synchronously. The rotation of the connecting rod 332 drives the slider 333 to slide along the slide groove 311. The opening piece 3331 hits the limit head 313, so that the limit head 313 passes through the through hole on the opening piece 3331. The largest end surface of the limit head 313 will limit the movement of the slider 333, and then lock the impact plate 322 and the telescopic member 321, so that the telescopic member 321 is in a compressed state. Subsequently, the fixing screw 314 can be removed using a tool, the limit head 313 can be pulled out, and the buffer member 32 is reset. If the spring 3213 can rebound freely after the first compression, then it will generate additional reverse force when it rebounds, which may cause severe vibration or impact. By locking the buffer member 32, it can ensure that the anti-collision mechanism 3 maintains a stable compression state when absorbing energy without unnecessary vibration or loss of control, thereby increasing the stability of the entire system to provide a more controllable shock absorption effect.
[0028] like Figure 1 As shown, the impact plate 322 and the anti-collision side strip 4 are both convex arc-shaped, and a cushion strip 41 is fixedly connected to one side of the anti-collision side strip 4. The cushion strip 41 can reduce the damage to the anti-collision side strip 4 after being hit.
[0029] like Figure 3 and Figure 6 As shown, a through groove 3221 is provided inside the striking plate 322, and a plurality of rotating drums 5 are rotatably connected inside the through groove 3221. A cavity 51 is provided inside the rotating drum 5, and a plurality of vertical bars 52 are arranged and fixed on the circumference of the rotating drum 5. When an external impactor hits the rotating drum 5, the cavity 51 inside the rotating drum 5 can make it soft and deform, thereby absorbing part of the collision energy and reducing the impact of the collision. The vertical bars 52 arranged on the circumference of the rotating drum 5 increase the contact friction between the rotating drum 5 and the impactor, so that the rotating drum 5 can be more easily rotated. The rotation design of the rotating drum 5 can disperse and slow down the collision energy.
[0030] Adopting the utility model, such as Figure 1 and Figure 2 As shown, the double-station RGV trolley usually runs along a straight line or a predetermined path, which means that the front and rear ends are more easily exposed to the area where collision may occur, while the two sides are relatively less likely to be hit, so anti-collision mechanisms 3 are installed at the front and rear ends for better protection. When the two sides of the double-station RGV trolley are hit, they will hit the anti-collision side strips 4 to deform and absorb energy, reducing the impact force on the double-station RGV trolley. When the front and rear ends are hit, they will hit the impact plate 322, causing the impact plate 322 to squeeze the telescopic member 321, and the slide bar 3212 slides into the inner part of the outer cylinder 3211, while compressing the spring 3213 to buffer the impact received by the double-station RGV trolley. The backward movement of the impact plate 322 will cause the support rod 331 to move backward synchronously, and the rotation of the connecting rod 332 drives the slide block 333 to slide along the slide groove 311, and the opening member 3331 hits the limit head 313, causing the limit head 313 to pass through the through hole on the opening member 3331. The maximum end surface of the limit head 313 will limit the movement of the slide block 333, thereby locking the double-station RGV trolley. The impact plate 322 and the telescopic member 321 are held so that the telescopic member 321 is in a compressed state. Subsequently, the fixing screw 314 can be removed using a tool, the limit head 313 can be pulled out, and the buffer member 32 is reset. If the spring 3213 can rebound freely after the first compression, additional reverse force will be generated when it rebounds, which may cause severe vibration or impact. By locking the buffer member 32, it can be ensured that the anti-collision mechanism 3 maintains a stable compression state when absorbing energy without unnecessary vibration or loss of control, thereby increasing the stability of the entire system to provide a more controllable shock absorption effect.

It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
