Description
Technical Field
[0001] This utility model relates to the field of cargo boxes, specifically to a cargo box tail beam assembly structure. Background Technology
[0002] The cargo box is an important component of a vehicle for transporting goods, and its design and function vary depending on transportation needs. Based on different uses and types of goods, cargo boxes can be divided into various types, including enclosed cargo boxes, open cargo boxes, refrigerated cargo boxes, self-unloading cargo boxes, and flatbed cargo boxes. These cargo box designs not only consider the protection of goods but also take into account the convenience of loading and unloading and transportation efficiency.
[0003] The existing cargo box includes a floor, with crossbeams and longitudinal beams at the bottom. It also includes side beams and longitudinal beams on the outer side of the floor. The floor is rotatably connected to the rear panel and side panels via the side beams. The crossbeams, side beams, longitudinal beams, and longitudinal beams are all C-shaped channel steel. The C-shaped channel steel includes a web and flanges on both sides of the web. A square groove is formed between the flanges and the web. The webs of the side beams and longitudinal beams are vertically arranged. The two ends of the crossbeams are fixed by embedding them into the longitudinal beams. The longitudinal beams are fixedly welded to the bottom of the crossbeams. The rear bottom of the existing cargo box needs to install components such as license plates and taillights. However, the taillights are damaged due to the large bumps during vehicle operation and the collisions between the rear panel and side panel and the side beams when the vehicle is flipped over. The taillights are difficult to install and repair because they are located at the rear bottom of the cargo box, requiring operators to disassemble and install them in a difficult posture, resulting in low efficiency. Utility Model Content
[0004] The present invention aims to provide a solution to the problem of easy damage and difficult maintenance of the rear lights of the cargo box.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cargo box rear crossbeam assembly structure, including a crossbeam, anti-collision brackets fixed to the bottom ends of the crossbeam and longitudinal crossbeam, and a taillight bracket fixed between the anti-collision bracket and the crossbeam. The anti-collision bracket is connected to anti-collision blocks at a position perpendicular to the web of the crossbeam and longitudinal crossbeam. A guide portion is provided between the taillight bracket and the crossbeam, and a positioning portion is provided between the taillight bracket and the anti-collision bracket. The taillight bracket is detachably connected to the crossbeam and the anti-collision bracket through the guide portion and the positioning portion. The guide portion is used to move and fix the taillight bracket toward the anti-collision bracket, and the positioning portion is used to fix the taillight bracket.
[0006] The beneficial effects of this solution are as follows: By setting anti-collision blocks perpendicular to the horizontal and vertical side beams, the side panels and rear panels will directly contact the anti-collision blocks after being flipped down, thus avoiding direct collision between the panels and the side beams, preventing paint damage and vibration, and preventing damage to the headlights caused by vibration. By setting guide and positioning parts, the taillight bracket can be detachably connected and fixed between the horizontal and vertical side beams. This allows maintenance personnel to remove the taillight bracket from the vehicle body and fix the taillight to the taillight bracket when replacing or installing the taillight, thus integrating the taillight bracket and taillight into the vehicle body and improving installation efficiency.
[0007] Preferably, as an improvement, the guide part includes a guide rod fixed to the top of the taillight bracket, a guide groove opened on the lower wing plate of the cross beam, and a plug slidably disposed on the guide rod. The guide groove is for the guide rod to slide and is L-shaped. The guide groove includes an inlet groove perpendicular to the web plate and opened on the lower wing plate, and a sliding groove parallel to the web plate. The sliding groove is connected to the inlet groove. The end of the sliding groove away from the inlet groove is close to the anti-collision bracket. The plug is used to be embedded in the sliding groove.
[0008] Preferably, as an improvement, the anti-collision block includes a horizontal anti-collision block and a vertical anti-collision block, both of which are bolted to the anti-collision bracket. The positioning part includes a positioning block fixed to the taillight bracket near the end of the anti-collision bracket and a positioning opening opened on the side of the anti-collision bracket near the taillight bracket. The positioning opening allows the positioning block to pass through. The positioning block has a first fixing hole and a second fixing hole corresponding to the horizontal anti-collision block and the vertical anti-collision block, respectively. The bolts fixing the horizontal anti-collision block and the vertical anti-collision block pass through the anti-collision bracket and are connected to the first fixing hole and the second fixing hole, respectively.
[0009] Preferably, as an improvement, it also includes a sealing plate fixedly connected to the transverse beam, the sealing plate being used to connect to the end of the longitudinal beam, and the sealing plate having a mounting position for installing a reversing radar.
[0010] Preferably, as an improvement, it also includes a license plate bracket fixed to the crossbeam.
[0011] Preferably, as an improvement, it also includes a reinforcing box fixed in the square groove of the transverse beam.
[0012] Preferably, as an improvement, the lower flange of the transverse beam has a positioning hole at the end of the sliding groove away from the inlet / outlet groove. The positioning hole is connected to the sliding groove. The plug is frustum-shaped, and the guide rod is threaded with a positioning nut at the bottom of the frustum.

[0020] The reference numerals in the accompanying drawings include: base plate 1, crossbeam 11, longitudinal beam 12, longitudinal edge beam 13, side panel 14, rear panel 15, transverse edge beam 2, anti-collision bracket 21, anti-collision block 211, transverse edge impact block 2111, longitudinal edge impact block 2112, positioning port 212, taillight bracket 22, guide rod 221, plug 2211, positioning nut 2212, guide groove 222, inlet / outlet groove 2221, sliding groove 2222, positioning block 223, first fixing hole 2231, second positioning hole 2232, connecting plate 224, sealing plate 23, mounting position 231, license plate bracket 24, reinforcing box 25, and positioning hole 26.
[0021] Example
[0022] The basic implementation examples are as follows: Figures 1-5 As shown, Figures 1-3 The diagram shows a cargo box rear crossbeam assembly structure, including a transverse beam 2. Anti-collision brackets 21 are fixedly welded to the bottom sides of the transverse beam 2 and the longitudinal beam 13. Each anti-collision bracket 21 includes a horizontal plate and a vertical plate arranged perpendicularly to each other. The horizontal and vertical plates are parallel to the webs of the transverse beam 2 and the longitudinal beam 13, respectively, and are vertically arranged, i.e., the cross-sections of the horizontal and vertical plates are L-shaped. A transverse impact block 2111 and a longitudinal impact block 2112 are detachably connected to the transverse and longitudinal plates of the anti-collision bracket 21 by bolts. The transverse and longitudinal impact blocks 2111 and 2112 are collectively referred to as anti-collision blocks 211. The anti-collision blocks 211 are injection molded from rubber material, resulting in high production efficiency and allowing for periodic replacement. The bolts connecting the anti-collision blocks 211 penetrate the anti-collision blocks 211 and the anti-collision bracket 21, entering the interior of the anti-collision bracket 21. A positioning plate is provided on the vertically folded edge of the transverse plate of the anti-collision bracket 21. Anti-collision brackets 21 are symmetrically arranged on both sides of the rear of the cargo box.
[0023] like Figures 4-5As shown, an L-shaped guide groove 222 is provided on the lower flange of the transverse beam 2. The guide groove 222 includes an inlet / outlet groove 2221 perpendicular to the web of the transverse beam 2 and a sliding groove 2222 parallel to the web of the transverse beam 2. The sliding groove 2222 and the inlet / outlet groove 2221 are connected. The inlet / outlet groove 2221 is opened on the side of the lower flange of the transverse beam 2 away from the web. The end of the sliding groove 2222 away from the inlet / outlet groove 2221 is close to the side of the anti-collision bracket 21. A detachable connection for installation is provided between the transverse beam 2 and the anti-collision bracket 21. The taillight bracket 22 is rectangular and has a reserved position for installing the taillight. Guide rods 221 are symmetrically fixed on both sides of the top of the taillight bracket 22. Connecting plates 224 are welded to the top of the guide rods 221. A plug 2211 is vertically slidably connected to the guide rod 221. The plug 2211 is frustum shaped and made of rubber. A positioning nut 2212 is bolted to the bottom of the plug 2211 on the guide rod 221.
[0024] A positioning block 223 is fixedly welded to the end of the taillight bracket 22. The positioning block 223 has a first fixing hole 2231 and a second fixing hole in the direction parallel to the horizontal plate and the vertical plate, respectively. The positioning plate of the anti-collision bracket 21 has a positioning opening 212 for the positioning block 223 to pass through. During installation, the guide rod 221 is inserted into the lower wing plate of the transverse beam 2 from the inlet / outlet groove 2221. At the same time, the lower wing plate is placed between the connecting plate 224 and the plug 2211. At this time, the taillight bracket 22 is suspended from the lower wing plate of the transverse beam 2 through the connecting plate 224 and slides closer to the web plate in the direction perpendicular to the web plate as the guide rod 221 slides. When the guide rod 221 slides to the inlet / outlet groove 2221 and enters the sliding groove 2222, the positioning block 223 is directly opposite the positioning opening 212. Push the taillight bracket 22 again, and the guide rod 221 slides in the sliding groove 2222 toward the anti-collision bracket 21. The positioning block 223 enters the anti-collision bracket 21 through the positioning port 212. When the guide rod 221 slides into the positioning hole 26, rotate the positioning nut 2212. The positioning nut 2212 drives the plug 2211 to move upward and finally pushes the plug 2211 against the positioning hole 26, thereby fixing the taillight bracket 22 onto the horizontal beam 2. Then, bolts are used to install the horizontal side impact block 2111 and the vertical side impact block 2112 onto the horizontal plate and the vertical plate respectively. The bolt end connecting the horizontal side impact block 2111 is threaded to the first fixing hole 2231, and the bolt end connecting the vertical side impact block 2112 is threaded to the second fixing hole.
[0025] like Figures 2-3As shown, it also includes a sealing plate 23 fixedly welded to the bottom end of the transverse beam 2. The sealing plate 23 corresponds to the longitudinal beam 12 on the vehicle body. The sealing plate 23 is used to cover the end of the longitudinal beam 12 to make the appearance neat. At the same time, the sealing plate 23 is provided with a reversing radar for installation. A license plate bracket 24 is fixedly welded to the middle of the bottom end of the transverse beam 2. The parts of the license plate bracket 24 are separately welded together, which greatly reduces the weight of the license plate bracket 24. At the same time, the license plate bracket is welded to the transverse beam 2 to avoid the regulatory risks of the license plate bracket 24 being detachable. A reinforcing box 25 is fixedly welded in the square groove of the transverse beam 2. The reinforcing box 25 is hollowed out to achieve lightweight while ensuring its load-bearing capacity.
