Description

Technical Field

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

[0002] With the development of the national economy and the continuous improvement of living standards, freight transportation is becoming increasingly important in daily life, and trailers are one of the most common modes of land transportation. Trailers generally do not have their own power units; they are simply mobile loading mechanisms consisting of a cargo box and wheels. When they need to transport goods, they must be used in conjunction with a tractor unit equipped with a drive mechanism. Therefore, trailers themselves focus more on their load-bearing capacity. New energy trailers, on the other hand, use new energy as their primary power source. However, existing new energy trailers still encounter some problems in actual use.

[0003] The following problems exist in existing new energy technologies:

[0004] 1. Trailers are large vehicles that carry heavy and bulky goods and are used for medium- and long-distance freight transport. During the transport process, trailers inevitably encounter complex road conditions. For example, when one of the trailer's tires goes out of bounds, the trailer will tilt, and in severe cases, it will overturn, affecting transport safety.

[0005] 2. When transporting heavy goods, during vehicle turns, the centrifugal force of the goods can cause some of the goods to shift. This shift may result in uneven pressure on the trailer at the bottom, which could cause the trailer at the bottom to tilt. If not corrected in time, this could lead to a rollover, causing damage to the goods or even affecting the safety of the transportation process.

[0006] 3. When the trailer is under load and turns, the cargo may cause the cargo support plate at the bottom to slide and shift, which may cause the cargo to slide and impact the cargo, potentially causing the cargo to fall off. This affects the stability of transportation and may also affect driving safety. Summary of the Invention

[0007] To address the shortcomings mentioned in the background section, the present invention aims to provide a new energy trailer anti-rollover frame structure that can provide anti-rollover protection during trailer travel, prevent cargo from falling off, prevent trailer rollover, and improve transportation stability.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A new energy trailer anti-tilt frame structure includes a trailer rear frame mechanism. The front end of the trailer rear frame mechanism is equipped with a direct bearing mechanism for directly bearing the top cargo, and the bottom end of the direct bearing mechanism is provided with an indirect bearing mechanism for assisting in stabilizing the top cargo.

[0010] The indirect bearing mechanism includes a movable pressure plate, an arc plate mounting claw at the top of the movable pressure plate, and a movable pressure shaft fixedly connected to the bottom of the movable pressure plate.

[0011] The bottom end of the indirect load-bearing mechanism is movably connected to a trailer frame structure for realizing the trailer's movement function.

[0012] The trailer frame structure includes an inner frame and a trailer connecting frame, and multiple limiting springs are arrayed on the inner side of the inner frame.

[0013] The trailer frame structure is fixedly connected to a trailer towing mechanism for connection with a tractor at one end away from the trailer rear frame mechanism.

[0014] Furthermore, the trailer rear frame mechanism includes a tail frame, a tail mounting plate is fixedly connected to the end of the tail frame away from the direct load-bearing mechanism, a mounting baffle is fixedly connected to the bottom end of the tail frame, wheel protection plates are fixedly connected to both ends of the mounting baffle, and trailer wheels are provided at the bottom end of the wheel protection plates.

[0015] Furthermore, the direct bearing mechanism includes a cargo bearing plate, with arc-shaped plates arranged in an array at the bottom end of the cargo bearing plate, and the cargo bearing plate is disposed at the top of the indirect bearing mechanism.

[0016] Furthermore, a rotating plate is rotatably connected to the outside of the movable pressure shaft, a movable support plate is fixedly connected to the outside of the rotating plate, a compression plate is slidably connected to the end of the movable support plate away from the rotating plate, and a fixed support plate is slidably connected to the outside of the compression plate.

[0017] Furthermore, the compression plate is fixedly connected to the baffle bracket through the fixed support plate. A sliding baffle is fixedly connected to the end of the baffle bracket away from the fixed support plate. A leak-proof cover is fixedly connected to the top of the sliding baffle. A vent pipe is fixedly connected to the top of the leak-proof cover. A lifting airbag is fixedly connected to the top of the vent pipe. A baffle plate is slidably connected to the outside of the sliding baffle. A vent pipe is fixedly connected to the bottom of the baffle plate at the position corresponding to the vent pipe. An air storage tank is fixedly installed at the end of the vent pipe away from the baffle plate.

[0018] Furthermore, the inner frame supports the compression plate by a limiting spring, and a support tube is fixedly connected to the bottom end of the inner frame, and a support base is fixedly connected to the bottom end of the support tube.

[0019] Furthermore, the trailer connecting frame is connected to the rear end of the tractor, and a central hanging rod is slidably connected to the bottom end of the trailer connecting frame. Spring push plates are provided at both ends of the outer side of the central hanging rod. A support spring is fixedly connected to the end of the spring push plate away from the central hanging rod, and a signal button is provided at the bottom end of the support spring.

[0020] Furthermore, the signal button is connected to a signal transmitter, which controls the fixing of the arc plate mounting claw to the top direct bearing mechanism by transmitting a signal.

[0021] Furthermore, both the support tube and the support base are hollow structures with multiple through holes on the outer side.

[0022] Furthermore, the trailer towing mechanism includes a towing plate, which is fixedly connected to the front end of the inner frame. Trailer protection plates are fixedly connected to both sides of the towing plate. A connecting bracket is fixedly connected to the end of the towing plate away from the trailer frame structure, and a bracket protection plate is fixedly connected to the front end of the connecting bracket.

[0023] The beneficial effects of this invention are:

[0024] 1. This invention employs a connection method between the trailer connecting frame and the tractor unit via a tractor unit-universal joint-fixed rod-rotation damping-fixed rod-spherical hinge. During the trailer's turning and driving process, the trailer connecting frame drives the central mounting rod to push the signal button. The signal button then drives the signal transmitter to control the arc plate mounting claw at the top of the moving pressure plate, enabling it to grip the arc plate at the top. This prevents the cargo bearing plate from sliding or shifting, improving the stability of the cargo during transportation and avoiding cargo detachment.

[0025] 2. During the turning process of the trailer, the present invention can utilize the weight of the cargo. When a tilt occurs, the compression plate and the limiting spring restrict the movement of the sliding baffle at the top of the leak-proof cover. This allows the air tank to support and lift the lifting airbag at the far tilt end of the frame through the air passage pipe. This lifting allows the tilt end to be raised to the top, preventing the tilt during the turning process from affecting the transportation of the cargo, improving stability, and avoiding a certain degree of risk of rollover.

[0026] 3. During use, when one tire falls off the ground, the trailer connecting frame first drives the central hook to push the signal button. The signal button then drives the signal transmitter to control the arc plate mounting claw at the top of the moving pressure plate, allowing it to grab the arc plate at the top. This prevents the cargo bearing plate from detaching. Simultaneously, the moving pressure plate on one side will rise. At this time, the compression plate at its far end will be pushed by the limit spring, ensuring that the baffle inside the leak-proof cover does not block the connection between the gas inside the ventilation pipe and the ventilation pipe. This allows the gas inside the air tank to enter the lifting airbag through the ventilation pipe and the leak-proof cover, pushing the corresponding frame, protecting the cargo at the top, preventing tilting, and improving stability.

[0038] 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.

[0039] 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.

[0040] A new energy trailer anti-rollover frame structure, such as Figure 1 As shown, the trailer includes a rear frame mechanism 1, a direct load-bearing mechanism 2 for directly carrying the top cargo is installed at the front end of the rear frame mechanism 1, an indirect load-bearing mechanism 3 for assisting in stabilizing the top cargo is provided at the bottom end of the direct load-bearing mechanism 2, a trailer frame structure 4 for realizing trailer movement is movably connected to the bottom end of the indirect load-bearing mechanism 3, and a trailer towing mechanism 5 for connecting with a tractor is fixedly connected to the end of the trailer frame structure 4 away from the rear frame mechanism 1.

[0041] The direct load-bearing mechanism 2 supports the cargo at the top, and the cargo at the top is placed on top of the direct load-bearing mechanism 2 to avoid contact between the cargo and the indirect load-bearing mechanism 3 at the bottom, thus preventing damage to the cargo and the indirect load-bearing mechanism 3. The trailer frame structure 4 is used to realize the movement function of the trailer, and the trailer traction mechanism 5 is used to cooperate with the tractor to realize the function of the tractor.

[0042] like Figure 2 As shown, the trailer rear frame mechanism 1 includes a tail frame 11. A tail mounting plate 12 is fixedly connected to one end of the tail frame 11 away from the direct load-bearing mechanism 2. A mounting baffle 13 is fixedly connected to the bottom end of the tail frame 11. Wheel protection plates 14 are fixedly connected to both ends of the mounting baffle 13. Trailer wheels 15 are provided at the bottom end of the wheel protection plates 14.

[0043] The tail frame 11 protects the cargo and prevents it from falling off and causing damage during the trailer's movement. The tail plate 12 works in conjunction with the tail frame 11 to provide protection. The trailer baffle 13 protects the bottom of the trailer and prevents damage to the internal mechanisms caused by external influences. The wheel protection plate 14 protects the trailer wheels 15 at the bottom and enables them to move.

[0044] like Figure 3As shown, the direct support mechanism 2 includes a cargo support plate 21, with arc-shaped plates 22 arranged in an array at the bottom end of the cargo support plate 21, and the cargo support plate 21 is located at the top of the indirect support mechanism 3.

[0045] The cargo at the top is kept stable by the cargo support plate 21, and the arc plate 22 is used to maintain the stability of the cargo support plate 21.

[0046] like Figure 4 and Figure 5 As shown, the indirect bearing mechanism 3 includes a movable pressure plate 31, an arc plate mounting claw 32 is provided at the top of the movable pressure plate 31, a movable pressure shaft 33 is fixedly connected to the bottom of the movable pressure plate 31, a rotating plate 34 is rotatably connected to the outside of the movable pressure shaft 33, a movable support plate 35 is fixedly connected to the outside of the rotating plate 34, a compression plate 36 is slidably connected to the end of the movable support plate 35 away from the rotating plate 34, and a fixed support plate 37 is slidably connected to the outside of the compression plate 36.

[0047] A compression plate 36 is fixedly connected to a baffle bracket 38 through a fixed support plate 37. A sliding baffle 39 is fixedly connected to the end of the baffle bracket 38 away from the fixed support plate 37. A leak-proof cover 310 is fixedly connected to the top of the sliding baffle 39. A vent pipe 311 is fixedly connected to the top of the leak-proof cover 310. A lifting airbag 312 is fixedly connected to the top of the vent pipe 311. A baffle plate 313 is slidably connected to the outside of the sliding baffle 39. A vent pipe 314 is fixedly connected to the bottom of the baffle plate 313 at the position corresponding to the vent pipe 311. An air tank 315 is fixedly installed at the end of the vent pipe 314 away from the baffle plate 313.

[0048] The top cargo-bearing plate 21 is stabilized by the arc plate mounting claw 32. The rotating plate 34 on the outside of the moving pressure shaft 33 is used to control the state of the movable support plate 35 in conjunction with the compression plate 36. The movable support plate 35 is moved by the moving pressure shaft 33 as the top moving pressure plate 31 moves to the lower end. Under the restriction of the fixed support plate 37, the movable support plate 35 is flipped outward and pushes the compression plate 36 outward. The fixed support plate 37 is used to control and guide the movement of the compression plate 36. The baffle bracket 38 follows the movement of the compression plate 36 and drives the sliding baffle 39 to move. As the barrier plate 313 moves inside, the compressed gas inside the gas tank 315 is output to the lifting airbag 312 through the ventilation pipe 314, passing through the leak-proof cover 310 and the ventilation pipe 311. The leak-proof cover 310 is provided with a baffle on its inner side. When the movable support plate 35 pushes the compression plate 36 to the farthest end, it can block the through hole of the ventilation pipe 314 at the bottom. When the movable support plate 35 flips to the top, the baffle inside the leak-proof cover 310 will no longer be able to block the ventilation pipe 314, and the gas inside the gas tank 315 can also be output to the lifting airbag 312 through the leak-proof cover 310.

[0049] The arc plate mounting claw 32 uses a commonly available miniature electric gripper to achieve the function of clamping upon receiving an electrical signal. The gripper that can be used is the FUYU brand electric gripper, model EGB-06.

[0050] like Figure 6 , Figure 7 and Figure 8 As shown, the trailer frame structure 4 includes an inner frame 41 and a trailer connecting frame 45. Multiple limiting springs 42 are arrayed on the inner side of the inner frame 41. The inner frame 41 supports the compression plate 36 through the limiting springs 42. A support tube 43 is fixedly connected to the bottom end of the inner frame 41, and a support seat 44 is fixedly connected to the bottom end of the support tube 43.

[0051] The trailer connecting frame 45 is connected to the rear end of the tractor. A central hanging rod 46 is slidably connected to the bottom end of the trailer connecting frame 45. Spring push plates 47 are provided at both ends of the outer side of the central hanging rod 46. A support spring 48 is fixedly connected to the end of the spring push plate 47 away from the central hanging rod 46. A signal button 49 is provided at the bottom end of the support spring 48.

[0052] The signal button 49 is connected to a signal transmitter, which controls the fixing of the arc plate mounting claw 32 to the top direct bearing mechanism 2 by transmitting a signal.

[0053] Both the support tube 43 and the support base 44 are hollow structures with multiple through holes on the outside.

[0054] During use, the limiting spring 42 inside the inner frame 41 is used to maintain the state of the compression plate 36 connected to it. By adjusting the limiting spring 42, the threshold of the load-bearing capacity of the movable support plate 35 when it is pressed to the bottom when it is carrying goods, that is, when the compression plate 36 is pushed to the limit position, is realized. The support tube 43 and the support seat 44 can maintain the stability of the entire trailer when the trailer is placed alone.

[0055] The trailer connecting frame 45 is connected to the tractor. When the tractor changes lanes or turns, the trailer connecting frame 45 can change its state as the tractor's cab moves. The connection between the trailer connecting frame 45 and the tractor is as follows: the rear end of the tractor is connected to a universal joint, the rear end of the universal joint is connected to a fixed rod, the fixed rod is connected to another fixed rod through rotational damping, the other fixed rod is connected to a ball hinge, and the ball hinge is connected to the trailer connecting frame 45.

[0056] The center hook 46 at the bottom of the trailer connecting frame 45 is used to cooperate with the push spring plate 47, so that the spring plate 47 is kept in the center position under the push of the support spring 48. When the truck head turns, the angle changes, and the center hook 46 resists the push of the support spring 48. Pressing the signal button 49 controls the signal transmitter to send a signal to the arc plate mounting claw 32 at the top, and controls it to receive the signal and grip the direct bearing mechanism 2 at the top.

[0057] like Figure 9 As shown, the trailer towing mechanism 5 includes a towing plate 51, which is fixedly connected to the front end of the inner frame 41. Trailer protection plates 52 are fixedly connected to both sides of the towing plate 51. A connecting bracket 53 is fixedly connected to the end of the towing plate 51 away from the trailer frame structure 4. A bracket protection plate 54 is fixedly connected to the front end of the connecting bracket 53.

[0058] The trailer is connected to the tractor via the connecting bracket 53 at the top of the towing bracket 51. The trailer protection plate 52 provides protection during the connection process, allowing the tractor to increase the contact area of ​​the trailer's load-bearing parts, thereby reducing pressure and providing protection for the tractor. The connecting bracket 53 is used to cooperate in the connection between the tractor and the trailer, and the bracket protection plate 54 is used to provide protection during the towing process and prevent damage, thereby improving the stability of the towing.

[0059] The fixed support plate 37 is fixedly connected to the inner frame 41, and serves to guide the movable support plate 35 to flip and move and the compression plate 36 to slide.

[0060] In use, first connect the tractor unit to the trailer protection plate 52, ensuring the trailer protection plate 52 is in working condition and the connection is secure. Then connect the trailer connecting frame 45 to the tractor unit. The connection method is as follows: a universal joint is connected to the rear end of the tractor unit, and a fixed rod is connected to the rear end of the universal joint. This fixed rod is connected to another fixed rod via rotational damping. The other fixed rod is connected to a ball joint, which in turn connects to the trailer connecting frame 45. This connection method allows the tractor unit to move the trailer connecting frame 45 during steering and lane changes, preventing fatigue fracture at the connection point of the trailer connecting frame 45 due to large steering angles. It also avoids vibrations during the connection process, which could cause trailer vibrations and affect the stability of the cargo.

[0061] When placing goods, the goods are placed on top of the goods support plate 21 of the direct support mechanism 2. During this process, as the weight of the goods increases, the goods support plate 21 will move downwards via the arc plate 22 and the arc plate mounting claw 32, causing the movable pressure plate 31 to move downwards. This movement will cause the movable support plate 35 to rotate via the movement of the movable pressure shaft 33 and the rotating plate 34. The outward movement of the movable support plate 35 will push the compression plate 36 outwards. This movement is constrained by the limit spring 42, so the appropriate limit spring 42 can be selected according to the total weight of the goods, thereby setting an appropriate threshold. This threshold is used to adjust the tilting limitation range. After the goods are placed, the goods will cause the movable support plate 35 to move to the position shown in the image. Figure 4At the position shown, the compression plate 36 will also push the limiting spring 42 to the end. This movement will cause the compression plate 36 to pass through the fixed support plate 37 and drive the baffle bracket 38 to move. The movement of the baffle bracket 38 will cause the sliding baffle 39 to move inside the barrier plate 313. This movement will move the sliding baffle 39 to both ends of the barrier plate 313. At this position, the baffle inside the leak-proof cover 310 blocks the vent pipe 314 at the bottom. Then, the gas tank 315 is installed, allowing the gas inside the gas tank 315 to pass through the vent pipe 314.

[0062] During the trailer's movement, the cargo will remain stable. However, during turning or lane changes, a certain degree of lateral tilting will occur. This is mainly because the cargo experiences centrifugal force during turning, and may even deviate to some extent. The pressure on the outer side will be greater than that on the inner side, thus creating a tendency to tilt. To prevent tilting, the tractor's turning will cause the trailer connecting frame 45 to move. The movement of the trailer connecting frame 45 will cause the center connecting rod 46 to move. The support spring 48, in conjunction with the spring push plate 47, resists the movement of the center connecting rod 46. When the turning radius exceeds the resistance limit of the support spring 48, the center connecting rod 46 will push the signal button 49. When the signal button 49 is pressed, a signal is transmitted to the signal transmitter. The signal controls the arc plate mounting claw 32 at the top, causing the arc plate mounting claw 32 to grip the arc plate 22 at the top, maintaining the stability of the cargo carrying plate 21 and preventing tilting.

[0063] When the tractor's steering angle is large and side tilting is inevitable, the distal end will tilt. At this time, the pressure on the proximal end will decrease, and the compression plate 36 at the proximal end will be pushed inward by its corresponding limiting spring 42. At this time, the sliding baffle 39 at the distal end connected to it will be moved inward. The baffle inside the leak-proof cover 310 will no longer be able to block the high-pressure gas in the bottom ventilation pipe 314. The high-pressure gas will be injected into the lifting airbag 312 through the ventilation pipe 311, allowing the lifting airbag 312 to output thrust to the top, preventing the side tilt from becoming more severe, maintaining the overall stability of the trailer, and achieving the goal of preventing side tilting.
