Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a large car box with an installation mechanism. Background Technology

[0002] "Car cargo box" usually refers to a large storage box or cargo box installed on a car. It is mainly used to increase the car's cargo space and facilitate the storage and transportation of goods. As an important component for transporting goods, the stability and convenience of the installation of the car cargo box are of paramount importance.

[0003] However, the existing methods for installing large truck beds still have some problems:

[0004] The existing installation structure of the truck bed is relatively complex. The bed is fixed by a number of bolts, which need to be tightened one by one during installation and loosened one by one during disassembly. This makes the installation and disassembly process cumbersome, requiring a lot of manpower and time, and is inefficient. Moreover, during transportation, the bed is easily impacted by the bumps and vibrations of the vehicle. The existing installation mechanism cannot effectively buffer these impacts, further reducing the stability of the bed and the cargo.

[0005] Therefore, we propose a large truck bed with an installation mechanism to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a large truck bed with an installation mechanism to solve the problem that the installation structure of the large truck bed mentioned in the background art is relatively complex. The large truck bed is fixed by a large number of bolts, which need to be tightened one by one during installation and loosened one by one during disassembly. This makes the installation and disassembly process cumbersome, requiring a lot of manpower and time costs, and is inefficient. Moreover, during transportation, the large truck bed is easily impacted by the bumps and vibrations of the vehicle. The existing installation mechanism cannot effectively buffer these impact forces, further reducing the stability of the large truck bed and the cargo.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a large car box with an installation mechanism, comprising a frame, a box body, a fixing frame, and a connecting rod. The box body is disposed on top of the frame, the fixing frame is welded to the rear end of the frame, and a connecting rod adapted to the fixing frame is welded to the bottom of the rear end of the box body, and the connecting rod and the fixing frame are rotatably connected by bolts.

[0008] The front end of the frame is welded with a base, the middle of the base is provided with a positioning groove, the bottom of the box is fixed with a positioning rod that matches the base, the bottom end of the positioning rod is fixed with a connecting block, the middle of the base is provided with a support rod, the outer surface of the support rod is provided with a spring, and the end of the support rod is fixed with a locking block.

[0009] Using the above technical solution, when the positioning rod at the bottom of the box is embedded in the base, the connecting block at the bottom of the positioning rod will abut against the locking block inside the base. When the connecting block moves downward, the locking block moves to one side of the connecting block. When the connecting block no longer abuts against the locking block, the locking block returns to its original position with the elastic action of the spring, so that the locking block is located at the upper end of the connecting block, thereby forming a locking and limiting function, which makes the connection between the box and the vehicle body convenient and improves the installation efficiency.

[0010] Preferably, the connecting block is frustum-shaped, and the locking block is triangular, and the locking block is engaged with the connecting block and the positioning rod.

[0011] By adopting the above technical solution, the special shapes of the frustum-shaped connecting block and the triangular locking block are used to make the locking block, connecting block and positioning rod form a locking connection. With the help of the spring on the support rod, the front end of the box is positioned and fixed, which facilitates the quick connection between the box and the frame and enhances the stability of the connection between the box and the front end of the frame. This prevents the box from shifting during use and ensures the installation stability of the truck box.

[0012] Preferably, the support rod is slidably connected to the base, one end of the spring is fixedly connected to the inner wall of the base, and the other end of the spring is fixedly connected to the side end face of the locking block.

[0013] Using the above technical solution, the support rod can slide inside the base. One end of the spring is fixed to the inner wall of the base, and the other end is connected to the locking block. Utilizing the elasticity of the spring, the locking block can lock or release the connecting block and the positioning rod, realizing flexible operation of connecting the front end of the box to the frame, which is convenient for installing and disassembling the box. At the same time, the elastic force provided by the spring ensures the stability of the locking block, connecting block, and positioning rod engagement, ensuring that the car box is firmly connected during use.

[0015] Using the above technical solution, the first connecting seat is rotatably connected to the first movable seat through the first fastening pin and can rotate around the first fastening pin. The adjusting link is composed of multiple sets of links spliced ​​together, one end of which is fixed to the outside of the first connecting seat and moves accordingly, so that the adjusting link can flexibly change the angle, which is convenient for connecting with other components and adjusting the position or angle to adapt to different installation requirements and working conditions of the automobile box.

[0016] Preferably, a second movable seat is welded to the bottom corner of the housing, a second connecting seat is rotatably connected to the inner side of the second movable seat, a second fastening pin passes through the middle of the second movable seat and the second connecting seat, and the other end of the adjusting rod is fixedly connected to the outer side of the second connecting seat.

[0017] Using the above technical solution, the second connecting seat rotates within the second movable seat by means of the second fastening pin, and the two ends of the adjusting rod are fixed to the first connecting seat and the second connecting seat respectively, transmitting the rotation adjustment action to realize the movable connection between the box and the frame. It can flexibly adjust the position and angle of the box relative to the frame, making the installation of the car box more adaptable to different situations, and greatly improving the versatility and applicability of the adjusting rod.

[0018] Preferably, a first buffer pad is attached to the upper surface of the frame, and fastening screws that are threaded to the frame are passed through the four corners of the first buffer pad. A second buffer pad corresponding to the first buffer pad is attached to the bottom of the housing.

[0019] By adopting the above technical solution, a first buffer pad and a second buffer pad are set between the vehicle frame and the box body. The elasticity of the buffer pad is used to alleviate vibration, and the first buffer pad is fixed to the vehicle frame with fastening screws. This reduces the vibration and friction between the vehicle frame and the box body during vehicle operation, protects the vehicle frame and the box body, improves the overall stability and service life of the truck box, enhances the stability and safety during transportation, and reduces the risk of cargo damage.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The base at the front of the frame has a positioning groove. When the positioning rod at the bottom of the housing is inserted into the base, the frustum-shaped connecting block at the bottom of the positioning rod will abut against the triangular locking block inside the base. When the connecting block moves downward, it will push the locking block to one side of the connecting block. When the connecting block moves downward and no longer abuts against the locking block, the locking block will return to its original position due to the elastic action of the spring, so that the locking block is located at the top of the connecting block, and the locking block, the connecting block and the positioning rod form a locking connection. This makes it easier and faster to install and disassemble the front of the housing and the frame, greatly shortening the operation time and improving work efficiency.

[0022] 2. A first buffer pad is attached to the upper surface of the frame, and a second buffer pad corresponding to the first buffer pad is attached to the bottom of the box. This allows the buffer pads to utilize their own elastic properties to effectively absorb and disperse the impact forces when the frame and box experience relative displacement or collision due to vibration or bumps during vehicle operation. This reduces direct friction and hard impacts between the frame and box, protects the surfaces of the frame and box from wear and damage, and extends the service life of the vehicle box.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] To address the issues of cumbersome installation and disassembly processes and the inability of existing installation mechanisms to effectively buffer impact forces in current technologies, the following solution is disclosed. Please refer to [link / reference]. Figures 1-6This utility model provides a technical solution: a large car box with an installation mechanism, including a frame 1, a box body 2, a fixing frame 3, and a connecting rod 4. The box body 2 is arranged on the top of the frame 1, and the fixing frame 3 is welded to the rear end of the frame 1. The connecting rod 4, which is adapted to the fixing frame 3, is welded to the bottom of the rear end of the box body 2, and the connecting rod 4 and the fixing frame 3 are rotatably connected by bolts. A base 12 is welded to the front end of the frame 1, and a positioning groove 13 is opened in the middle of the base 12. A positioning rod 14, which is adapted to the base 12, is fixed to the bottom of the box body 2. A connecting block 15 is fixed to the bottom end of the positioning rod 14. A support rod 16 passes through the middle of the base 12. A spring 17 is provided on the outer surface of the support rod 16, and a locking block 18 is fixed to the end of the support rod 16. The connecting block 15 is frustum-shaped, and the locking block 18 is triangular, and the locking block 18 is engaged with the connecting block 15 and the positioning rod 14. The support rod 16 is slidably connected to the base 12, and one end of the spring 17 is fixedly connected to the inner wall of the base 12, while the other end of the spring 17 is fixedly connected to the side end face of the locking block 18.

[0032] The fixing bracket 3 at the rear end of the frame 1 is rotatably connected to the connecting rod 4 at the rear end of the housing 2 by bolts, providing rotational support for the rear end of the housing 2. The base 12 at the front end of the frame 1 has a positioning groove 13. When the positioning rod 14 at the bottom of the housing 2 is embedded in the base 12, the frustum-shaped connecting block 15 at the bottom of the positioning rod 14 will abut against the triangular locking block 18 inside the base 12. When the connecting block 15 moves downward, it will push the locking block 18 to one side of the connecting block 15. When the connecting block 15 moves downward and no longer abuts against the locking block 18, the locking block 18 returns to its original position due to the elastic action of the spring 17, so that the locking block 18 is located on the upper end of the connecting block 15, and so that the locking block 18, the connecting block 15, and the positioning rod are all in contact with each other. 14 forms a locking connection. Conversely, during disassembly, the support rod 16 can be pulled, causing the locking block 18 to move, thereby releasing the locking action between the locking block 18 and the connecting block 15 and the positioning rod 14. This facilitates the disconnection of the box 2 from the frame 1, achieving a stable and flexible connection between the box 2 and the frame 1. The rotating connection at the rear end of the frame 1 and the box 2 facilitates adjustment of the box 2's angle. The positioning and locking structure at the front end ensures accurate positioning during installation. The elasticity provided by the spring 17 guarantees connection stability, preventing the box 2 from shaking or shifting during driving, ensuring the safety of the vehicle box, greatly shortening operation time, improving work efficiency, and enhancing the convenience of installation and disassembly.

[0033] A first movable seat 5 is welded to one corner of the frame 1. A first connecting seat 6 is rotatably connected to the inner side of the first movable seat 5. A first fastening pin 7 passes through the middle of the first connecting seat 6 and the first movable seat 5. An adjusting rod 8 is fixed to the outer side of the first connecting seat 6. A second movable seat 9 is welded to the bottom corner of the housing 2. A second connecting seat 10 is rotatably connected to the inner side of the second movable seat 9. A second fastening pin 11 passes through the middle of the second movable seat 9 and the second connecting seat 10. The other end of the adjusting rod 8 is fixedly connected to the outer side of the second connecting seat 10.

[0034] The first movable seat 5 at one corner of the frame 1 is rotatably connected to the first connecting seat 6 via the first fastening pin 7, allowing the first connecting seat 6 to rotate flexibly around the first fastening pin 7. The adjusting rod 8, fixed to the outside of the first connecting seat 6, moves along with it. At the same time, the second movable seat 9 at the bottom corner of the box 2 is rotatably connected to the second connecting seat 10 via the second fastening pin 11. The other end of the adjusting rod 8 is fixed to the outside of the second connecting seat 10. Based on the movable connection structure, by rotating the first connecting seat 6 and the second connecting seat 10, the relative position and angle of the box 2 and the frame 1 can be adjusted using the transmission of the adjusting rod 8. This allows the car box to be more accurately fitted to the frame 1 during installation, adapting to the differences in the frame 1 of different car models, enhancing the flexibility and stability of installation, reducing wear between the box 2 and the frame 1 caused by improper installation, and improving the overall reliability and service life of the car box.

[0035] A first buffer pad 19 is attached to the upper surface of the frame 1. Fastening screws 20, which are threaded to the frame 1, pass through the four corners of the first buffer pad 19. A second buffer pad 21, corresponding to the first buffer pad 19, is attached to the bottom of the housing 2.

[0036] A first buffer pad 19 is attached to the upper surface of the frame 1, and fastening screws 20 are threaded through the four corners of the first buffer pad 19 and connected to the frame 1 to secure the first buffer pad 19. At the same time, a second buffer pad 21 corresponding to the first buffer pad 19 is attached to the bottom of the box 2. This allows the buffer pads to effectively absorb and disperse the impact force when the frame 1 and the box 2 experience relative displacement or collision due to vibration or bumps during vehicle operation. This reduces direct friction and hard collisions between the frame 1 and the box 2, protects the surfaces of the frame 1 and the box 2 from wear and damage, and extends the service life of the truck bed. In addition, the vibration damping also reduces the risk of damage to goods due to vibration during transportation, improving the stability and safety of transportation.

[0037] Working principle: For this type of car box with an installation mechanism, during installation, the rear end fixing bracket 3 of the frame 1 and the rear end connecting rod 4 of the box 2 are connected by bolts, which facilitates the adjustment of the rear end angle of the box 2. The positioning groove 13 of the front end base 12 of the frame 1 cooperates with the positioning rod 14 of the box 2. The frustum-shaped connecting block 15 and the triangular locking block 18 are engaged and disengaged under the action of the spring 17, which facilitates the installation and disassembly of the front end of the box 2. The first movable seat 5 and the first connecting seat 6 at one corner of the frame 1, and the second movable seat 9 and the second connecting seat 10 at the bottom corner of the box 2 are respectively connected by fastening pins. The adjusting rod 8 connects the two, which can adjust the relative position and angle of the box 2 and the frame 1 to adapt to different vehicle models. In addition, the first buffer pad 19 and the second buffer pad 21 attached to the frame 1 and the box 2 use their elasticity to absorb the vibration and impact force during vehicle operation, reduce the friction and collision between the frame 1 and the box 2, protect the box 2 and the cargo, and ensure the stability and safety of the car box during installation and use.

[0038] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
