[0002] An RV, also known as a "home on wheels", is a means of transportation that combines the two major functions of "house" and "vehicle", and its essential attribute is a vehicle. The RV integrates "clothing, food, housing, and transportation", realizing the concept of "traveling in life and living in travel". This type of vehicle originated from the caravans of the Gypsies. After years of development, RVs already have a rich range of household facilities, including bedding, stoves, refrigerators, cabinets, sofas, dining tables and chairs, washing facilities, air conditioners, TVs, stereos, etc., and can be divided into a driving area, a living area, a bedroom area, a sanitary area, and a kitchen area according to their functions.

[0003] For example, the disclosed CN213262274U provides a vehicle anti-collision rear bumper, which relates to the field of RVs and includes a bumper beam. One side of the bumper beam is fixedly installed with a bumper. Both ends of the bumper are fixedly connected with fixing blocks. The two fixing blocks are rotatably connected with support rods through rotating members. One end of each of the two support rods is rotatably connected with a substrate through a rotating member. An anti-collision device is arranged on one side of the substrate on both sides. In the utility model, the buffer member on the buffer device can prevent external impacts and reduce the damage and deformation of the substrate. The support device can connect and fix the substrate to prevent the substrate from falling off during bumps, reducing the impact on the bumper caused by the external impact on the substrate after the impact. The two support rods can fix and position the substrate and can also share the gravity of the substrate borne by the two connecting rods on the support device, so that the position of the buffer can be limited when the substrate is impacted.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a reinforced rear bumper for a motorhome, including a structural main body:

[0033] The structural main body includes an anti-collision beam 11. The top end of the anti-collision beam 11 is fixedly connected to a reinforced rear bumper 12. An impact plate 13 is arranged above the reinforced rear bumper 12. A buffer structure is arranged below the impact plate 13. An adjustment structure is arranged on one side of the impact plate 13. A fixing structure is arranged inside the impact plate 13;

[0034] The installation main body includes an insert rod 21. The insert rod 21 is inserted on both sides of the reinforced rear bumper 12. The insert rod 21 penetrates through the reinforced rear bumper 12. An installation structure is arranged on one side of the insert rod 21.

[0035] As Figure 1 and Figure 2 shown, one end of the anti-collision beam 11 away from the reinforced rear bumper 12 is fixedly connected with fixed seats 111 in a linear array. The structural main body is connected and fixed through the threaded grooves on the fixed seats 111. The buffer structure includes first mounting seats 141. The first mounting seats 141 are arranged on both sides below the impact plate 13. The middle of the first mounting seats 141 is rotatably connected with a movable plate 142. One side of the movable plate 142 away from the first mounting seat 141 is rotatably connected with a moving seat 143. One side of the moving seat 143 away from the movable plate 142 is slidably connected with a slide bar 144. The slide bar 144 is fixedly connected with the chute on the reinforced rear bumper 12. The outer wall of the slide bar 144 is sleeved with a first spring 145.

[0036] In this embodiment, the structure is installed and fixed through the threaded holes on the fixed seat 111. When the impact plate 13 is impacted, the movable plate 142 installed on the first mounting seat 141 drives the movable seat 143 to slide on the sliding rod 144, compressing the first spring 145, so that the movable seat 143 coincides with the buffer block inside the reinforced rear bumper 12 to buffer the impact force.

[0037] As Figures 2 to 4 shown, the adjusting structure includes a mounting block 151 and a movable plate 153. The mounting blocks 151 are respectively clamped at both ends of the impact plate 13 close to the reinforced rear bumper 12. The mounting blocks 151 are fixedly connected to the first mounting seat 141. Card slots 152 are provided on both sides of the mounting block 151.

The fixing structure includes a clamping block 161. The clamping block 161 is slidably connected to the grooves on both sides inside the impact plate 13. The clamping block 161 is clamped with the card slot 152. One end of the clamping block 161 away from the mounting block 151 is fixedly connected to a third spring 162. The third spring 162 is fixedly connected to the groove inside the impact plate 13.

[0038] In this embodiment, when the movable plate 142 needs to be replaced, hold the movable seat 143 and press it. The movable plate 153 fixed at one end of the movable seat 143 squeezes the second spring 154 as the movable seat 143 is pressed. The movable plate 142 generates a certain pulling force on the first mounting seat 141 as the second spring 154 is compressed. The clamping block 161 connected to the card slot 152 is squeezed and moved as the movable plate 142 is pulled. The third spring 162 fixed at one end of the clamping block 161 is compressed as the clamping block 161 moves, so that the clamping block 161 is removed from the card slot 152, releasing the fixation of the mounting block 151. The mounting block 151 is removed from the impact plate 13 as the movable plate 142 is pulled, so that the buffer structure is removed from the reinforced rear bumper 12, facilitating the quick replacement and installation of the buffer structure.

[0039] As Figure 1 and Figure 5As shown in the figure, connection seats 131 are fixedly connected to both ends of the impact plate 13 close to the reinforced rear bumper 12. One end of the connection seat 131 is fixedly connected to a fixing block 132. The fixing block 132 is snap-connected to the reinforced rear bumper 12. The reinforced rear bumper 12 penetrates through the fixing block 132 and is inserted into the fixing block 132. The installation structure includes a fixing frame 221. The fixing frame 221 is fixedly connected to both sides of one end of the reinforced rear bumper 12. A threaded rod 222 is threadedly connected to the side of the fixing frame 221 away from the reinforced rear bumper 12. Push blocks 223 and extrusion blocks 224 are respectively fixedly connected to both ends of the outer wall of the threaded rod 222. A connecting rod 225 is threadedly connected to one side of the threaded rod 222. The threaded rod 222 penetrates through the connecting rod 225. The push block 223 and the extrusion block 224 are in a pushing connection with the connecting rod 225. Moving shafts 226 are fixedly connected to both ends of the fixing frame 221. Connecting frames 227 are rotatably connected to both sides of the connecting rod 225. The connecting frames 227 are rotatably connected to the moving shafts 226. Limiting blocks 228 are fixedly connected to the opposite sides of the connecting frames 227. The limiting blocks 228 are snap-connected to the insertion rod 21.

[0040] In this embodiment, when it is necessary to replace the damaged impact plate 13, hold the threaded rod 222 and rotate it on the fixing frame 221 and the connecting rod 225. The push block 223 fixed to one end of the threaded rod 222 moves as the threaded rod 222 rotates and pushes the connecting rod 225. The connecting frames 227 connected to both sides of the connecting rod 225 rotate on the moving shafts 226 due to the thrust generated by the connecting rod 225, causing the limiting blocks 228 snap-connected to the insertion rod 21 to move, releasing the fixation of the insertion rod 21. Hold the insertion rod 21 and pull it to remove the insertion rod 21 from the fixing block 132 and the reinforced rear bumper 12, releasing the fixation between the reinforced rear bumper 12 and the impact plate 13, facilitating the replacement and installation of the impact plate 13 and improving the convenience of replacement.

[0041] Working principle: First, the structure is installed and fixed through the threaded holes on the fixing base 111. When the impact plate 13 is impacted, the movable plate 142 installed on the first mounting seat 141 drives the movable seat 143 to slide on the slide rod 144, compressing the first spring 145, so that the movable seat 143 coincides with the buffer block inside the reinforced tail bar 12 to buffer the impact force. Then, when the impact plate 13 is damaged due to the impact force, hold the threaded rod 222 and rotate it on the fixing frame 221 and the connecting rod 225. The pushing block 223 fixed at one end of the threaded rod 222 moves with the rotation of the threaded rod 222 to push the connecting rod 225. The connecting frames 227 connected to both sides of the connecting rod 225 rotate on the movable shaft 226 with the thrust generated by the connecting rod 225, causing the limiting block 228 clamped on the plug rod 21 to move, releasing the fixation of the plug rod 21. Hold the plug rod 21 and pull it out from the fixing block 132 and the reinforced tail bar 12, releasing the fixation between the reinforced tail bar 12 and the impact plate 13, facilitating the replacement of the impact plate 13. When it is necessary to replace the movable plate 142, hold the movable seat 143 and press it. The moving plate 153 fixed at one end of the movable seat 143 squeezes the second spring 154 with the pressing of the movable seat 143. The movable plate 142 generates a certain pulling force on the first mounting seat 141 with the compression of the second spring 154. The clamping block 161 connected in the card slot 152 is squeezed and moved with the pulling of the movable plate 142. The third spring 162 fixed at one end of the clamping block 161 is compressed with the movement of the clamping block 161, so that the clamping block 161 is removed from the card slot 152, releasing the fixation of the mounting block 151. The mounting block 151 is pulled out of the impact plate 13 with the pulling force of the movable plate 142, and the buffer structure is pulled out of the reinforced tail bar 12, enabling the rapid removal and replacement of the buffer structure.

[0042] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
