Description

Technical Field

[0001] This invention relates to the field of new energy vehicle structural technology, specifically a new energy trailer frame structure with a buffer structure. Background Technology

[0002] Trailers generally lack their own power unit; they are simply mobile loading mechanisms consisting of a cargo box and wheels. When transporting goods, they need to be used in conjunction with a tractor unit equipped with a drive mechanism. Therefore, trailers primarily focus on their load-bearing capacity. New energy trailers, on the other hand, use new energy sources as their main power source. However, existing new energy trailers still encounter some problems in practical use.

[0003] The following problems exist in the use of existing new energy trailers:

[0004] 1. In the case of a new energy trailer in the present technology, when it is rear-ended by a vehicle, the lack of a corresponding buffer mechanism can cause greater injury to the driver of the vehicle behind due to the lack of cushioning. Since the trailer is relatively high, the rear-end vehicle is more likely to be hit by the trailer.

[0005] 2. The existing buffer mechanisms of new energy trailers mainly transfer the impact force from the rear of the vehicle to the vehicle frame directly during a rear-end collision. This buffering method can easily damage the vehicle frame, affecting the overall structural safety of the trailer and creating safety hazards.

[0006] 3. Existing new energy trailers have the problem that when rear-ended, the impact force can cause the cargo carried by the trailer to fall off from the rear. The falling cargo may be damaged, and it may also cause impact to the following vehicles, resulting in injury to the following vehicles or even the drivers behind them. Summary of the Invention

[0007] To address the shortcomings mentioned in the background section, the present invention aims to provide a new energy trailer frame structure with a buffer structure.

[0018] Furthermore, the transmission mechanism includes a fixed push frame, a first transmission support rod rotatably connected to the inner side of the fixed push frame, a first transmission bracket rotatably connected to the end of the first transmission support rod away from the fixed push frame, limit springs fixedly connected to the inner sides of the first transmission brackets at both ends, a second transmission support rod rotatably connected to the end of the first transmission bracket away from the first transmission support rod, and a movable push frame rotatably connected to the end of the second transmission support rod away from the first transmission bracket.

[0019] Furthermore, the primary transfer mechanism includes a moving central rod, with multiple arrayed moving connecting rods fixedly connected to the outside of the moving central rod. Each moving connecting rod is fixedly connected to a lifting buffer damper, and a damping rotation center is rotatably connected to the top of the lifting buffer damper.

[0025] 3. The present invention uses a rear-mounted cargo protection plate, which uses impact force to support the rear protection plate, thus protecting the cargo from falling off from the rear. It can protect the cargo carried by the trailer and also protect the vehicle from rear-impact collisions. Compared with the existing technology that uses strapping for protection, it can more effectively prevent the cargo from falling off and causing injury to the following vehicle and driver.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0037] A new energy trailer frame structure with a buffer structure, such as Figure 1 As shown, the system includes a frame mechanism 1, a trailer traction mechanism 2 for connecting to a tractor at the front end of the frame mechanism 1, an anti-fall protection mechanism 3 for supporting the cargo at the rear end of the frame mechanism 1, an impact buffer mechanism 4 for absorbing impact force at the bottom end of the anti-fall protection mechanism 3, a transmission mechanism 5 for transmitting and buffering the impact force at the front end of the impact buffer mechanism 4, a primary transfer mechanism 6 for transferring the impact force to the frame mechanism 1 and the cargo at the front end of the transmission mechanism 5, the primary transfer mechanism 6 being slidably connected to the bottom end of the frame mechanism 1, and a secondary transfer mechanism 7 for buffering and transferring the impact force on the outside of the primary transfer mechanism 6.

[0038] The frame mechanism 1 enables the trailer to carry cargo. The trailer traction mechanism 2 works with the trailer's tractor to achieve traction. The anti-fall protection mechanism 3 uses the weight of the cargo itself to protect it from falling off. The impact buffer mechanism 4 is used to bear the impact from the rear of the trailer and buffer the impact. The transmission mechanism 5 transfers the impact to the first-level transfer mechanism 6 after the impact buffer mechanism 4 has borne the impact. The first-level transfer mechanism 6, in conjunction with the second-level transfer mechanism 7, transfers the impact from the rear of the frame mechanism 1 to the frame mechanism 1 and the cargo at the top of the frame mechanism 1. The frame mechanism 1 and the cargo disperse the impact force and provide buffering.

[0039] like Figure 2 As shown, the frame mechanism 1 includes a trailer frame 11, a wheel protection plate 12 is fixedly connected to the outside of the trailer frame 11, a trailer wheel 13 is provided at the bottom of the wheel protection plate 12, an inner frame 14 is fixedly connected to the inside of the trailer frame 11, and a rear bracket 15 is provided at the top of the rear end of the trailer frame 11.

[0040] The wheel protection plate 12 on the outside of the trailer frame 11 protects the trailer wheels 13 at the bottom, preventing impacts from the top from affecting the trailer's function. The inner frame 14 is used to support the trailer frame 11 and carry goods.

[0041] The trailer traction mechanism 2 includes a traction base plate 21, a traction hook 22 is fixedly connected to the top of the traction base plate 21, a hook buffer plate 23 is fixedly connected to the front end of the traction hook 22, and side buffer plates 24 are fixedly connected to both sides of the hook buffer plate 23.

[0042] The traction function is achieved by the traction hook 22 at the top of the traction base plate 21 in conjunction with the tractor vehicle. The hook buffer plate 23 and the side buffer plate 24 are used to provide protection during the connection between the tractor vehicle and the trailer.

[0043] like Figure 3 As shown, the anti-fall protection mechanism 3 includes a rear frame 31, and a lifting and pushing cylinder 32 is rotatably connected to the top of the rear frame 31. A cylinder output rod 33 is provided at the end of the lifting and pushing cylinder 32 away from the rear frame 31.

[0044] A movable groove 34 is slidably connected to the outside of the cylinder output rod 33. A cargo protection plate 35 is fixedly connected to the outside of the movable groove 34. A protection plate support 36 is fixedly connected to the bottom of the cargo protection plate 35. A protection plate pressure plate 37 is fixedly connected to the end of the protection plate support 36 away from the cylinder output rod 33.

[0045] By pressing the cargo onto the top of the protective plate 37, the protective plate support 36 works with the cargo protection plate 35 to achieve cargo loosening protection. The moving groove 34, together with the lifting push cylinder 32 and the cylinder output rod 33, supports the cargo protection plate 35 to further achieve protection.

[0046] like Figure 4 As shown, the impact buffer mechanism 4 includes a buffer positioning frame 41 and a moving guide groove 47. The buffer positioning frame 41 is fixedly connected to the bottom end of the trailer frame 11. A rotating groove tube 42 is fixedly connected to the bottom end of the buffer positioning frame 41. A rotating slide groove 43 is provided on the outer side of the rotating groove tube 42. A pressure plate bracket 44 is slidably connected to the inner side of the rotating slide groove 43. A transmission pressure plate 45 is rotatably connected to the end of the pressure plate bracket 44 away from the rotating slide groove 43. A buffer protection plate 46 is slidably connected to the end of the transmission pressure plate 45 away from the pressure plate bracket 44. The moving guide groove 47 is opened on the inner side of the trailer frame 11. The buffer positioning frame 41 is slidably connected to the inner side of the moving guide groove 47. A push spring is provided on the inner side of the moving guide groove 47.

[0047] The buffer protection plate 46 directly bears the impact of the rear end. After bearing the impact, it pushes the transmission pressure plate 45, allowing the transmission pressure plate 45 to slide in the rotating slide groove 43 on the outside of the rotating groove tube 42 in conjunction with the pressure plate bracket 44. The transmission pressure plate 45 pushes the transmission mechanism 5, and at the same time, the push spring inside the moving guide groove 47 is used to assist the buffer positioning frame 41 in driving the rotating groove tube 42 to move, further realizing the buffer.

[0048] like Figure 5As shown, the transmission mechanism 5 includes a fixed push frame 51, a first transmission support rod 52 is rotatably connected to the inner side of the fixed push frame 51, a first transmission bracket 53 is rotatably connected to the end of the first transmission support rod 52 away from the fixed push frame 51, a limit spring 54 is fixedly connected to the inner side of the first transmission bracket 53 at both ends, a second transmission support rod 55 is rotatably connected to the end of the first transmission bracket 53 away from the first transmission support rod 52, and a movable push frame 56 is rotatably connected to the end of the second transmission support rod 55 away from the first transmission bracket 53.

[0049] The first transmission support rods 52 on both sides of the fixed push frame 51 can withstand the impact force from the transmission pressure plate 45, so that the transmission pressure plate 45 drives the first transmission support rods 52 to fold inward, causing the first transmission bracket 53 to compress the limiting spring 54, achieving partial buffering. At the same time, the second transmission support rod 55 is also pushed, driving the movable push frame 56 to move.

[0050] like Figure 6 As shown, the primary transfer mechanism 6 includes a moving center rod 61, with multiple arrayed moving connecting rods 62 fixedly connected to the outside of the moving center rod 61. Each moving connecting rod 62 is fixedly connected to a lifting buffer damper 63, and a damping rotation center 64 is rotatably connected to the top of the lifting buffer damper 63. A bearing base plate 65 is fixedly connected to the top of the damping rotation center 64. A moving rotating bracket 66 is fixedly connected to the outside of the moving center rod 61 at a position away from the transmission mechanism 5.

[0051] The movement of the movable push frame 56 causes the movable center rod 61 to slide, and the movable center rod 61 causes the movable connecting rod 62 to slide. The damping rotation center 64 at the top of the lifting buffer damper 63 works in conjunction with the lifting buffer damper 63 to buffer the impact force and transfer the impact force to the damping rotation center 64 at the top. Part of the impact force is transferred to the inner frame 14 at the top of the bearing base plate 65, and the movement of the movable center rod 61 drives the movable rotating bracket 66.

[0052] like Figure 7 As shown, the secondary transfer mechanism 7 includes an airbag storage box 71, which is fixedly connected to the inner side of the trailer frame 11. A transverse plate 72 is slidably connected to the inner side of the airbag storage box 71. A buffer airbag 73 is fixedly connected to the top of the transverse plate 72, and a rotating plate 74 is fixedly connected to the top of the buffer airbag 73.

[0053] A rotating connecting bracket 75 is fixedly connected to the outer end of the rotating plate 74 away from the airbag storage box 71. The rotating connecting bracket 75 is rotatably connected to the inner side of the movable rotating bracket 66. A transmission lifting rod 76 is provided at the top of the rotating plate 74. The transmission lifting rod 76 is rotatably connected to the inner side of the trailer frame 11.

[0054] The movement of the rotating support 66 drives the rotating connecting support 75. The rotating connecting support 75 is driven, thereby causing the transverse plate 72 and the rotating plate 74 to move out of the airbag storage box 71. The buffer airbag 73 inflates and pushes the rotating plate 74. The rotating plate 74 is used to push the transmission lifting rod 76 to transfer the impact force to the top, so that the cargo at the top can bear part of the impact force, avoiding the problem of excessive impact force and damage to the trailer frame 11.

[0055] In use, cargo is placed on top of the trailer frame 11, with some cargo resting on top of the protective plate 37. The cargo on top of the protective plate 37 uses its own weight to control the position of the protective plate 35, preventing cargo from falling off the trailer when it is impacted, thus avoiding secondary damage to out-of-control vehicles caused by the impact. Simultaneously, when the buffer protective plate 46 at the rear bottom of the trailer frame 11 is impacted, it will activate the lifting cylinder 32, causing the cylinder output rod 33 of the lifting cylinder 32 to slide and move within the moving groove 34, further preventing cargo from detaching rearward after impact, protecting the cargo and preventing secondary damage.

[0056] Upon impact, the buffer protection plate 46 first moves inward, which drives the transmission pressure plate 45. The transmission pressure plate 45, together with the pressure plate bracket 44, slides inside the rotating slide groove 43 on the outside of the rotating tube 42, allowing the transmission pressure plate 45 to push the first transmission support rod 52. The first transmission support rod 52 flips and drives the second transmission support rod 55 through the first transmission bracket 53, causing the moving pusher 56 to be pushed forward. If the impact force is too high, the rotating tube 42 is also driven, and is moved by the springs inside the buffer positioning frame 41 and the moving guide groove 47.

[0057] The moving center rod 61 is pushed and driven by the moving pusher 56, causing the moving connecting rod 62 to move. This causes the damping rotation center 64 at the top of the lifting buffer damper 63 to output, allowing the bearing base plate 65 to bear part of the impact force. The impact force is then transmitted to the trailer frame 11 through the inner frame 14 at the top of the bearing base plate 65, allowing the trailer frame 11 to bear part of the impact force. At the same time, the moving rotating bracket 66 is driven by the movement of the moving center rod 61, causing the rotating connecting bracket 75 to move. The movement of the rotating connecting bracket 75 drives the transverse plate 72 and the rotating plate 74 until the rotating plate 74 is completely disengaged from the airbag storage box 71. At this point, the compressed gas inside the buffer airbag 73 expands, pushing the rotating plate 74. The rotating plate 74 then drives the transmission lifting rod 76 to flip to the top, transmitting the impact force to the cargo at the top. This allows the weight of the cargo to also be used to withstand the impact force, further improving the buffering effect.
