Description

Technical Field

[0001] This utility model relates to the field of heavy-duty truck vehicle structure technology, and in particular to a novel combined frame assembly for heavy-duty trucks. Background Technology

[0002] In heavy-duty truck transportation operations, the toolbox is a key component used to store maintenance tools, spare parts, emergency supplies, and other items. The performance of its combined frame structure directly affects the storage safety, accessibility, and service life of the tools. Currently, the combined frame structures of the toolboxes equipped on heavy-duty trucks are mainly of the fixed type, the simple folding type, and the split splicing type.

[0003] Especially when the vehicle is traveling on rough roads, the tools in the toolbox will move significantly with the vehicle's bumps, changing their position. When the driver or mechanic opens the toolbox, those unstable tools are very likely to fall out. Falling tools may not only injure people, but if they fall into the driver's cabin, they may also interfere with the driver's operation and cause a safety accident. If they fall onto the road outside the vehicle, they will pose a serious threat to the driving safety of vehicles behind.

[0004] In view of the above situation, this utility model is hereby proposed! Utility Model Content

[0005] To overcome the technical defects of existing technologies, this utility model provides a novel combined frame assembly specifically for heavy-duty trucks. The U-shaped opening door rotates around a pivot pin to form an upward-facing loading and unloading opening, conforming to operational habits and ensuring efficient storage and retrieval. An arc-shaped groove and positioning protrusion ensure smooth opening and closing. Handles, springs, and locking wedges enable quick locking and unlocking. A safety pin provides double protection, saving time and effort during operation and making it suitable for high-intensity work. Through holes in the load-bearing plate, combined with rope fixing tools, a reinforcing net provides secondary positioning, and a barrier net prevents falling. Multiple layers of protection avoid collisions. A funnel bottom and drainage trough quickly drain accumulated water, while ventilation pipes keep the area dry, preventing tool rust and minimizing work interruptions. The rotating sleeve and pivot pin balance flexibility and strength, resisting repeated opening and closing. A fixed sliding rod provides stable guidance, and the locking wedges self-lock to prevent bumpy door opening. The modular design adapts to multiple vehicle models, and the high-strength materials resist deformation, enhancing durability and safety.

[0006] The technical solution adopted by this utility model is: a novel heavy-duty truck-specific combined frame assembly, including a cargo box. A U-shaped opening door is provided on one side of the cargo box. A rotating sleeve is fixedly installed on the bottom surface of the U-shaped opening door. A pivot pin is rotatably connected inside the rotating sleeve. The pivot pin is fixedly installed on the bottom side of the cargo box. The U-shaped opening door rotates around the pivot pin to open, at which time the cargo box forms an upward-opening loading and unloading port. Compared with traditional side-opening or top-opening doors, the upward-opening loading and unloading port conforms to operating habits, eliminating the need for excessive bending and turning, making it more convenient to store and retrieve tools and improving efficiency. When opened, the U-shaped opening door and the cargo box form a clamp, which can prevent tools from falling out. The rotating sleeve and the pivot pin cooperate to ensure flexible and stable rotation, reduce jamming, and ensure a firm connection that can withstand repeated forces and extend service life.

[0007] Furthermore, the surface of the U-shaped opening door is provided with an arc-shaped groove, and a positioning protrusion is slidably connected in the arc-shaped groove. The positioning protrusion is fixedly installed on one side surface of the cargo box. The arc-shaped groove and the positioning protrusion slide together, which can accurately guide the U-shaped opening door to rotate along a preset trajectory, avoiding damage to the door body due to deviation and collision with the cargo box. At the same time, it can limit the rotation angle, prevent excessive opening from affecting operation or causing structural damage, and improve the safety and reliability of use.

[0008] Furthermore, a barrier net is installed on the bottom surface of one side opening of the cargo box. The barrier net is used to block the tools in the cargo box. The barrier net can effectively prevent the tools from falling out of the cargo box opening due to bumps during vehicle travel. Especially when the U-shaped opening door is not fully closed or accidentally loose, it can play a secondary protection role, reduce tool loss and safety accidents caused by falling tools, and ensure road driving safety.

[0009] Furthermore, the bottom of the storage box is equipped with a drainage channel. The bottom of the storage box is funnel-shaped, and the drainage channel is located at the lowest point of the bottom of the storage box. The funnel-shaped bottom design allows water to naturally collect in the drainage channel at the lowest point and then be discharged out of the storage box in a timely manner, preventing water from remaining inside. This effectively prevents tools from rusting and being damaged due to prolonged contact with water, extending the service life of the tools, while keeping the inside of the storage box dry, reducing bacterial growth and odor generation.

[0010] Furthermore, a reinforcing mesh is installed inside the cargo box, and a bearing plate is installed on the surface of the reinforcing mesh. The bearing plate has several through holes on its surface. The reinforcing mesh enhances the structural strength inside the cargo box, disperses the pressure on the bearing plate, and prevents deformation of the inner wall of the cargo box due to excessive tool weight. The through holes on the surface of the bearing plate can be used with ropes, buckles, and other fixing tools to achieve personalized fixing of tools of different sizes and shapes, prevent tools from shaking and colliding during transportation, and reduce tool wear.

[0011] Furthermore, a fixed sliding rod is installed in a strip groove on one side surface of the U-shaped opening door. A handle is slidably connected to the surface of the fixed sliding rod, and a spring is fitted onto the surface of the fixed sliding rod. One end of the spring abuts against one side of the handle, and the other end abuts against the strip groove on one side surface of the U-shaped opening door. One end of the handle passes through the U-shaped opening door and is connected to a connecting strip on one side of the U-shaped opening door. A locking wedge is fixedly installed on the surface of the connecting strip. A locking wedge groove adapted to the locking wedge is opened on the inner top surface of the cargo box. The fixed sliding rod provides stable guidance for the sliding of the handle, ensuring that the handle does not deviate when moving. The spring force can automatically push the handle back to its original position when the handle is released, so that the locking wedge is tightly inserted into the locking wedge groove, realizing the quick locking of the U-shaped opening door, which is convenient and labor-saving to operate. The wedge surface of the locking wedge and the locking wedge groove have a self-locking function, which can maintain the locked state when the vehicle is moving bumpy, preventing the U-shaped opening door from opening accidentally and improving the structural safety.

[0012] Furthermore, a fixing plate is fixedly installed on one side of the handle, and a safety pin is threaded onto the surface of the fixing plate. One end of the safety pin passes through the fixing plate and is inserted into a positioning hole opened on one side of the U-shaped opening door. After the U-shaped opening door is locked, the safety pin further fixes the position of the handle to prevent the locking wedge from disengaging from the locking wedge groove due to spring aging or vibration, thus playing a double safety role.

[0013] Furthermore, a ventilation pipe is installed on one side of the U-shaped opening door. The ventilation pipe is inclined downward on the side away from the U-shaped opening door. The ventilation pipe enables air circulation inside and outside the storage box, which can promptly remove moisture and odors from the box, keep the tools dry, and prevent rust. The downward inclined design of the ventilation pipe can effectively block rainwater, dust and other debris from entering the box while ensuring ventilation, avoiding contamination and damage to the tools. It can play a good protective role, especially in severe weather conditions.

[0014] The beneficial effects of this utility model are as follows: This new type of heavy-duty truck-specific combined frame assembly features a U-shaped opening door that rotates around a pivot pin to open, forming an upward-facing access opening that conforms to human operating habits, eliminating the need for excessive bending or turning. Tool access is more efficient. The arc-shaped groove and positioning protrusion work together to ensure a stable and smooth opening and closing process, avoiding jamming and collisions. The combination design of the handle, spring, and locking wedge enables quick locking and unlocking of the door. The safety pin provides double protection. Overall operation is time-saving and labor-saving, and it is suitable for the high-intensity and fast-paced needs of heavy-duty truck operations.

[0015] The through-holes in the support plate, combined with ropes, allow for flexible securing of various tools. A reinforced installation net provides secondary positioning, while a barrier net prevents tools from falling if the door becomes loose. Multiple layers of protection prevent tools from shaking and colliding during transport. The funnel-shaped bottom and drainage trough quickly drain accumulated water, and the ventilation pipe keeps the inside of the box dry, effectively preventing tool rust, extending service life, and reducing work interruptions due to tool damage. The connection between the rotating sleeve and the axle pin balances the flexibility of door rotation with structural strength, and can withstand the forces of repeated opening and closing. The fixed sliding rod provides stable guidance for the handle, and the self-locking function of the locking wedge and locking groove ensures the door does not open accidentally when the vehicle is bumpy. The modular design of each component adapts to various heavy-duty truck models, and the entire assembly is made of high-strength materials with strong deformation resistance, significantly improving the durability of the frame assembly and driving safety.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figure 1-5 As shown, this embodiment provides a novel heavy-duty truck-specific combined frame assembly, including a cargo box 1. A U-shaped opening door 2 is provided on one side of the cargo box 1. A rotating sleeve 5 is fixedly installed on the bottom surface of the U-shaped opening door 2. A shaft pin 6 is rotatably connected inside the rotating sleeve 5. The shaft pin 6 is fixedly installed on the bottom of one side of the cargo box 1. The U-shaped opening door 2 rotates around the shaft pin 6 to open, at which time the cargo box 1 forms an upward-facing loading and unloading port.

[0024] The U-shaped door 2, which rotates around the pivot pin 6 to open, overcomes the limitations of traditional side-opening or top-opening doors. Its upward-facing access opening design aligns with the user's habits when retrieving tools, eliminating the need for excessive bending or turning, thus improving work efficiency. Furthermore, the upward-facing access opening between the U-shaped door 2 and the storage box 1 prevents tools from falling out. The cooperation between the rotating sleeve 5 and the pivot pin 6 ensures the flexibility and stability of the U-shaped door 2 during rotation, reducing jamming. This robust structure can withstand repeated forces during opening and closing, extending its service life.

[0025] Furthermore, the surface of the U-shaped opening door 2 is provided with an arc-shaped groove 3, and a positioning protrusion 4 is slidably connected in the arc-shaped groove 3. The positioning protrusion 4 is fixedly installed on one side surface of the cargo box 1.

[0026] The sliding engagement between the arc groove 3 and the positioning protrusion 4 provides precise guidance for the rotation of the U-shaped opening door 2, ensuring that it rotates along the preset trajectory and preventing damage to the door body from collision with the cargo box 1 due to rotational deviation. At the same time, the cooperation of the two can limit the rotation angle of the U-shaped opening door 2, preventing over-opening that could affect operation or cause structural damage, thus improving the safety and reliability of use.

[0027] Furthermore, a barrier net 15 is installed on the bottom surface of one side opening of the cargo box 1. The barrier net 15 is used to block tools in the cargo box 1.

[0028] The barrier net 15 can effectively prevent tools from falling out of the cargo box 1 opening due to bumps during vehicle operation. Especially when the U-shaped door 2 is not fully closed or accidentally loose, it can play a secondary protective role, reducing tool loss and safety accidents caused by falling tools, and ensuring road driving safety.

[0029] Furthermore, a drainage groove 12 is provided at the bottom of the cargo box 1. The bottom of the cargo box 1 is funnel-shaped, and the drainage groove 12 is located at the lowest point of the bottom of the cargo box 1.

[0030] The funnel-shaped bottom design allows water to naturally collect in the drain trough 12 at the lowest point, and then be promptly drained out of the box, preventing water from remaining inside. This effectively prevents tools from rusting and being damaged due to prolonged contact with water, extending their service life, while keeping the inside of the storage box 1 dry, reducing bacterial growth and odor.

[0031] Furthermore, a reinforcing mesh 13 is installed inside the cargo box 1, and a bearing plate 14 is installed on the surface of the reinforcing mesh 13. Several through holes are opened on the surface of the bearing plate 14.

[0032] The reinforcement mesh 13 enhances the internal structural strength of the cargo box 1, disperses the pressure on the bearing plate 14, and prevents the inner wall of the cargo box 1 from deforming due to excessive tool weight. The through holes on the surface of the bearing plate 14 can be used with ropes, buckles and other fixing tools to achieve personalized fixing of tools of different sizes and shapes, prevent tools from shaking and colliding during transportation, and reduce tool wear.

[0033] Furthermore, a fixed slide rod 20 is installed in the strip groove 16 opened on one side surface of the U-shaped door 2. A handle 17 is slidably connected to the surface of the fixed slide rod 20. A spring 21 is sleeved on the surface of the fixed slide rod 20. One end of the spring 21 abuts against one side of the handle 17, and the other end of the spring 21 abuts against the strip groove 16 opened on one side surface of the U-shaped door 2. One end of the handle 17 passes through the U-shaped door 2 and is connected to the connecting strip 24 set on one side of the U-shaped door 2. A locking wedge 22 is fixedly installed on the surface of the connecting strip 24. A locking wedge groove 23 that matches the locking wedge 22 is opened on the inner top surface of the cargo box 1.

[0034] The fixed slide bar 20 provides stable guidance for the sliding of the handle 17, ensuring that the handle 17 does not deviate when moving. The elastic force of the spring 21 can automatically push the handle 17 back to its original position when it is released, so that the locking wedge 22 is tightly inserted into the locking wedge groove 23, realizing the quick locking of the U-shaped door 2, which is convenient and labor-saving to operate. The wedge surface of the locking wedge 22 and the locking wedge groove 23 have a self-locking function, which can maintain the locked state when the vehicle is moving bumpy, preventing the U-shaped door 2 from opening accidentally, thus improving the safety of the structure.

[0035] Furthermore, a fixing plate 18 is fixedly installed on one side of the handle 17. A safety pin 19 is threadedly connected to the surface of the fixing plate 18. One end of the safety pin 19 passes through the fixing plate 18 and is inserted into a positioning hole opened on one side of the U-shaped door 2.

[0036] After the U-shaped door 2 is locked, the safety pin 19 further secures the position of the handle 17, preventing the locking wedge block 22 from dislodging from the locking wedge groove 23 due to aging of the spring 21 or vibration, thus providing a double safety function.

[0037] Furthermore, a ventilation pipe 11 is installed on one side surface of the U-shaped door 2, and the ventilation pipe 11 is inclined downward on the side away from the U-shaped door 2.

[0038] The ventilation duct 11 allows air circulation inside and outside the storage box 1, which can promptly remove moisture and odors from the box, keep the tools dry, and prevent rust. The downward-sloping design of the ventilation duct 11 ensures ventilation while effectively blocking rainwater, dust, and other debris from entering the box, avoiding contamination and damage to the tools. It also provides good protection, especially in harsh weather conditions.

[0039] Working principle: When the U-shaped door 2 needs to be opened, first unscrew the safety pin 19 to disengage it from the positioning hole on the U-shaped door 2, then pull the handle 17. The handle 17 slides on the fixed slide bar 20. At this time, the spring 21 is compressed, and the handle 17 drives the connecting bar 24 to move, thereby causing the locking wedge block 22 to disengage from the locking wedge groove 23. Then, push and pull the U-shaped door 2. The U-shaped door 2 rotates around the shaft pin 6. During the rotation, the positioning protrusion 4 slides in the arc groove 3, which guides and limits the rotation of the U-shaped door 2 to prevent it from rotating excessively. Finally, the U-shaped door 2 rotates to the appropriate position, and the storage box 1 forms an upward-opening loading and unloading port for easy access to tools.

[0040] When closing the U-shaped door 2, push the U-shaped door 2 in the opposite direction to make it rotate around the pivot pin 6 to close. The positioning protrusion 4 slides in the opposite direction in the arc groove 3. When the U-shaped door 2 is closed to a certain position, release the handle 17. Under the elastic force of the spring 21, the handle 17 returns to its original position, driving the connecting strip 24 and the locking wedge 22 to move, so that the locking wedge 22 is inserted into the locking wedge groove 23, realizing the initial fixation of the U-shaped door 2. Finally, screw the safety pin 19 into the fixing plate 18 and insert it into the positioning hole of the U-shaped door 2 to further enhance the stability of the U-shaped door 2 after it is closed.

[0041] The tool is placed on the support plate 14 inside the cargo box 1. The through holes on the surface of the support plate 14 can be used with ropes, buckles, etc. to fix the tool and prevent it from moving during transportation. The reinforcement net 13 not only supports the support plate 14, but also limits the tool to a secondary position to prevent it from shaking significantly. When the U-shaped door 2 is closed, the barrier net 15 can block the tool if it moves accidentally, preventing the tool from falling out of the opening of the cargo box 1.

[0042] The funnel-shaped design at the bottom of the storage box 1 allows water inside the box to collect in the lowest drainage trough 12 and drain out of the box, preventing tools from rusting and being damaged due to water accumulation. The ventilation pipe 11 on the U-shaped opening door 2 allows air circulation inside and outside the storage box 1, keeping the box dry. At the same time, its downward tilt design prevents rainwater from entering the box through the ventilation pipe 11.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
