Description

Technical Field

[0001] This utility model relates to the field of sanitation vehicle technology, specifically to a sanitation vehicle anti-collision structure. Background Technology

[0002] The core function of the anti-collision structure of sanitation vehicles is to absorb collision energy and reduce impact transmission. That is, when a sanitation vehicle is parked and working (such as garbage collection and road sweeping) or in motion, it is hit by a vehicle from behind or to the side. The impact force is dissipated through structural deformation and compression of buffer materials, thereby reducing damage to the vehicle body, chassis and equipment inside the vehicle, and at the same time reducing injury to the other vehicle and personnel involved in the collision.

[0003] Chinese Patent Publication No. CN220701010U discloses a sanitation vehicle anti-collision structure, including a sanitation vehicle body and an anti-collision component. The anti-collision component is installed on the rear side of the sanitation vehicle body. The anti-collision component includes a door installed on the rear side of the sanitation vehicle body via a hinge. A first adapter is rotatably connected to the side of the mounting head away from the sanitation vehicle body. A hydraulic rod is rotatably connected to the side of the first adapter away from the mounting head. An anti-collision box is fixedly connected to the bottom of the connecting block. A collision avoidance warning component is provided on the side of the door away from the sanitation vehicle body. By setting the warning component, the sanitation vehicle anti-collision structure can effectively remind vehicles behind to maintain a safe distance in real time and promptly warn drivers of vehicles behind, thereby effectively reducing the occurrence of collisions and thus effectively reducing unnecessary losses to a certain extent.

[0004] In the aforementioned prior art, a crash box can be installed on the side of the sanitation vehicle door to buffer the impact when it is hit. The crash box can be opened and closed by using a hydraulic rod. However, the adjustment of the crash box depends on the control of the hydraulic rod. The use of the hydraulic rod requires the use of auxiliary components such as hydraulic pumps, oil pipes, and valves. The overall structure cost is high, and the cost of maintenance and replacement will increase when the crash box is deformed and damaged by an impact. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a collision protection structure for sanitation vehicles, thereby solving the problem mentioned in the background art where the adjustment of the sanitation vehicle collision protection box relies on hydraulic rod control. The use of hydraulic rods requires the use of auxiliary components such as hydraulic pumps, oil pipes, and valves, resulting in high overall structural costs and increased maintenance and replacement costs when the vehicle is deformed or damaged by an impact.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: like Figures 1 to 6 As shown, this utility model provides a sanitation vehicle anti-collision structure, including: a sanitation vehicle 1 rotatably mounted on the vehicle door 101, and a buffer structure arranged on one side of the vehicle door 101 for buffering when subjected to impact.

[0026] The buffer structure includes a T-shaped positioning frame 2 arranged on one side of the carriage door 101, a mounting frame 201 slidably sleeved on the T-shaped positioning frame 2, a movable frame 202 rotatably mounted on the mounting frame 201, a crash box 203 arranged on one side of the movable frame 202, and a support seat 204 arranged on one side of the carriage door 101 and located below the mounting frame 201. The movable frame 202 can be flipped on the mounting frame 201 to drive the crash box 203 to unfold or retract. The crash box 203 can be made of plastic, with a hollow interior that can be filled with cushioning materials such as polyurethane foam or honeycomb foam, so as to cushion the impact when hit by a vehicle from behind.

[0027] The buffer structure also includes a fixing screw 205 threaded inside the mounting bracket 201, an insertion hole 206 inside the T-shaped positioning bracket 2, the fixing screw 205 being inserted into the insertion hole 206, and a positioning screw 207 being inserted inside the movable bracket 202. The positioning screw 207 is threaded inside the support base 204. After the movable bracket 202 and the anti-collision box 203 are flipped and unfolded, the positioning screw 207 can be passed through the movable bracket 202 and screwed into the support base 204 to fix the angle of the anti-collision box 203.

[0028] Example 2: Based on Example 1, an adjustment structure is arranged on the buffer structure to facilitate the adjustment of the buffer structure for storage or unfolding.

[0029] The adjustment structure includes a connecting shaft 3 rotatably installed inside the mounting frame 201, a take-up roller 301 arranged at one end of the connecting shaft 3, a connecting rope 302 wound on the take-up roller 301, one end of the connecting rope 302 arranged on the take-up roller 301, and a rotating component 303 rotatably installed on one side of the crash box 203 and arranged at one end of the connecting rope 302. Rotating the take-up roller 301 can release the wound connecting rope 302, so that the crash box 203 drives the movable frame 202 to flip downward under its own weight. The support seat 204 provides support and angle restriction for the crash box 203, so that the crash box 203 can be unfolded and used.

[0030] The adjustment structure also includes a guide wheel 304 that is rotatably mounted on one side of the mounting frame 201. The guide wheel 304 is in contact with the connecting rope 302, and the connecting rope 302 can be guided by the guide wheel 304.

[0031] Example 3: Based on Example 2, in order to limit and reinforce the adjustment structure while the buffer structure is in the stored state, a limiting structure that works in conjunction with the adjustment structure is arranged on the buffer structure.

[0032] The limiting structure includes a toothed ring 4 fixedly sleeved on the take-up roller 301, a guide rod 401 arranged on one side of the mounting frame 201, and a toothed plate 402 slidably sleeved on the guide rod 401 and meshing with the toothed ring 4. When the toothed ring 4 and the toothed plate 402 are meshed, they can restrict the take-up roller 301 and prevent it from rotating. Pulling the toothed plate 402 can make it slide on the guide rod 401 and disengage from the toothed ring 4, thereby releasing the restriction on the take-up roller 301.

[0033] The limiting structure also includes a stop 403 arranged at one end of the guide rod 401 and an elastic component arranged on the toothed plate 402 for pressing the toothed plate 402. The stop 403 can prevent the toothed plate 402 from slipping off the guide rod 401.

[0034] Specifically, the elastic component includes a spring 404 that is slidably sleeved on the guide rod 401. The two ends of the spring 404 are respectively arranged between the toothed plate 402 and the stop block 403. When the toothed plate 402 moves, it will compress the spring 404. When the toothed plate 402 is released, the compressed spring 404 will push the toothed plate 402 to re-engage with the toothed ring 4. Thus, under the elastic force of the spring 404, the toothed plate 402 and the toothed ring 4 can be kept in an engaged state to prevent them from loosening. The spring 404 can be made of a relatively hard metal material to prevent it from loosening due to bumps when the vehicle is driving.

[0035] Working principle: (Reference) Figure 1 In operation, pulling the toothed plate 402 allows it to slide on the guide rod 401. As the toothed plate 402 moves, it compresses the spring 404 and disengages from the toothed ring 4, releasing the restriction on the take-up roller 301. Rotating the take-up roller 301 then releases the wound connecting rope 302, causing the crash box 203 to tilt downwards under its own weight, making lateral contact between the crash box 203 and the support base 204. The support base 204 provides support and angle limitation for the crash box 203, ultimately resulting in... Figure 2 When in the desired state, the crash box 203 can be unfolded for use. The crash box 203 can be made of plastic, with a hollow interior that can be filled with cushioning materials such as polyurethane foam or honeycomb foam. It can cushion the impact of a rear vehicle collision. Conversely, when the crash box 203 needs to be folded, simply rotate the winding roller 301 in the opposite direction to wind up the connecting rope 302. Under the pull of the connecting rope 302, the crash box 203 can be flipped and folded. After completion, the toothed plate 402 can be released. At this time, the retracted spring 404 will push the toothed plate 402 to re-engage with the toothed ring 4, which can limit the angle of the winding roller 301 and prevent the connecting rope 302 from becoming loose. This allows for easy retraction and expansion as needed. By rotating the fixing screw 205 and unscrewing it from the insertion hole 206, the connection restriction between the mounting bracket 201 and the T-shaped positioning bracket 2 can be released. Then, by pushing the mounting bracket 201 upward, it can be removed from the T-shaped positioning bracket 2, so that the damaged anti-collision box 203 can be disassembled and replaced. When the truck door 101 is flipped open, it will drive the T-shaped positioning bracket 2, the mounting bracket 201, the anti-collision box 203 and other components installed on the side to rotate together, so as not to affect the dumping of garbage in the sanitation vehicle 1. The T-shaped positioning bracket 2 and the support base 204 can be fixed to the truck door 101 by welding.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
