Description

Technical Field

[0001] This utility model relates to the field of automotive cargo box technology, and in particular to a high-load-bearing single-row large-capacity cargo box for pickup trucks. Background Technology

[0002] Pickup trucks, as a type of vehicle that combines cargo carrying and passenger use, are widely used in daily life and work. As an important component for carrying cargo, the load-bearing capacity and volume of the cargo box directly affect the practicality of the pickup truck.

[0003] Chinese patent document CN201620128806.3 discloses a novel pickup truck cargo box with a wheel arch-less structure. The cargo box includes a cargo box with two rear wheels at the bottom, the distance between which is greater than the width of the cargo box. The cargo box has an inner cargo box panel and an outer cargo box panel on both sides, with a reinforcing plate between the inner and outer panels. The surface of the inner cargo box panel is horizontal and does not contain any protrusions. This novel pickup truck cargo box with a wheel arch-less structure achieves wheel avoidance of the cargo box by adjusting the rear wheel track without affecting the vehicle's passability. The horizontal surface of the inner cargo box panel, free of protrusions, maximizes the cargo box's load-bearing capacity for large items and reduces the investment in sheet metal molds required for wheel arches in the inner cargo box panel. This design is worthy of widespread promotion.

[0004] However, the above-mentioned patents have certain defects in use. Most of the pickup truck cargo boxes have simple structures and certain limitations in terms of load-bearing capacity and volume. They are also inadequate in terms of cargo box cleaning. When the bottom of the cargo box is covered with mud, debris, etc., it is difficult to clean and requires manual cleaning, which is not only time-consuming and labor-intensive, but also has poor cleaning effect.

[0005] To address these issues, a high-load-bearing single-row, large-capacity cargo box for pickup trucks is proposed. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

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

[0023] like Figures 1 to 4 As shown, a high-load-bearing single-row, large-capacity cargo box for pickup trucks includes a base 1, side panels, a front panel 3, and a rear panel 5. The side panels include a left side panel 4 and a right side panel 2. The side panels and the front panel 3 are fixedly connected around each other. The rear panel 5 is rotatably connected to the rear of the side panels, forming a rectangular frame. The rear panel 5 is connected to the side panels via buckles 51. The rear panel 5 is connected to the side panels via a rotatable connection (such as a hinge) to achieve the function of opening and closing. Buckles 51 are located at the upper end of the rear panel 5. When the rear panel 5 is closed, buckles 51 cooperate with corresponding structures on the front panel 3 or side panels to firmly fix the rear panel 5, preventing it from automatically opening due to vibration during driving. The buckles 51 are located at the upper end of the rear panel 5. This buckle connection method facilitates the opening and closing of the rear panel 5 and makes loading and unloading of goods easier. The side panels, front panel 3, and rear panel 5 together form the frame of the cargo box, providing lateral support and protection for the goods and preventing damage to the goods due to shaking during driving. The base 1 is fixed to the lower end of the side panel, front panel 3 and rear panel 5, providing stable support for the entire cargo box. The upper end of the base 1 is equipped with a cleaning device, which is used to clean the base 1 on the cargo box.

[0024] The cleaning device includes a motor 6, which is fixed to the back of the front enclosure 3. The motor 6 provides power to the cleaning device. The output end of the motor 6 is equipped with a lead screw, which extends through the front enclosure 3 to the rear enclosure 5. The end of the lead screw is equipped with a limiting plate 64, and a bearing is provided on the limiting plate 64. The end of the lead screw passes through the inner ring of the bearing. The lead screw rotates under the drive of the motor 6, and the thread on its surface engages with the thread in the sliding sleeve 66, converting the rotational motion of the lead screw into the linear motion of the sliding sleeve 66. The limiting plate 64 and the bearing at the end of the lead screw prevent the sliding sleeve 66 from dislodging from the end of the lead screw, and the bearing ensures the smooth rotation of the lead screw and reduces frictional resistance. The setting of the limiting plate 64 and the bearing ensures the stability of the lead screw rotation. A guide rod 63 is also provided through the front enclosure 3. The guide rod 63 is arranged parallel and symmetrically to the lead screw, and the end of the guide rod 63 is also equipped with a limiting plate 64. The guide rod 63 serves to guide the movement direction of the scraper 61.

[0025] The lead screw is provided with a sliding sleeve 66, and a scraper 61 is fixedly provided on the sliding sleeve 66. The two sides of the scraper 61 are sleeved on the lead screw and guide rod 63, and the lead screw and guide rod 63 pass through the scraper 61. This structure allows the scraper 61 to make linear reciprocating motion under the rotation of the lead screw and the guidance of the guide rod 63. The bottom of the scraper 61 is also provided with a scraper head 62, which contacts the surface of the base 1. During the movement of the scraper 61, the scraper head 62 can scrape off the mud, debris and other objects on the base 1 to achieve the cleaning function.

[0026] The base 1 is also equipped with two shields 7, which are symmetrically arranged on both sides of the base 1, above the lead screw and guide rod 63, to shield them. The shields 7 can prevent dirt, debris, etc. from entering the working area of ​​the lead screw and guide rod 63 and affecting their normal operation. At the same time, they play a certain protective role and extend the service life of the cleaning device. When cleaning is required, simply remove the shields 7 and start the motor 6 to perform the cleaning function.

[0027] The left side enclosure 4 includes a side frame 42, a side plate 41, and a side reinforcing tube 43. There are two side plates 41, which are fixed on both sides of the side frame 42 respectively. There are two side reinforcing tubes 43, which are fixed between the side plates 41. This structure enhances the strength and stability of the left side enclosure 4. The left side enclosure 4 is exactly the same as the right side enclosure 2.

[0028] The base 1 has multiple bottom reinforcing tubes 11 inside, and a support plate 12 is provided at the upper end of each bottom reinforcing tube 11. The support plate 12 is fixed to the upper surface of the base 1. The bottom reinforcing tubes 11 enhance the load-bearing capacity of the base 1, while the support plate 12 further disperses the pressure of the cargo on the base 1, improving the structural strength and stability of the base 1. The base 1 is connected to the pickup truck body or other supporting structures through its large contact area, evenly distributing the weight of the cargo and cargo box, avoiding damage caused by excessive local stress. The bottom reinforcing tubes 11 and the upper support plate 12 further enhance the load-bearing capacity. The bottom reinforcing tubes 11 disperse pressure through their own structural strength, while the support plate 12 distributes the pressure of the cargo more evenly on the base 1.

[0029] The working principle of this utility model is as follows: When loading goods, the operator opens the rear enclosure 5 by operating the buckle 51 and puts the goods into the cargo box from the rear enclosure 5. The goods are placed on the base 1. Due to the rectangular frame structure formed by the side enclosure, front enclosure 3 and rear enclosure 5, the goods are restricted within the cargo box space. When unloading is required, the buckle 51 is operated again to open the rear enclosure 5 and take the goods out of the cargo box.

[0030] When the cargo box base 1 needs cleaning, remove the two shields 7, and the operator starts the motor 6. The motor 6 starts running, and its output shaft drives the lead screw to rotate. When the lead screw rotates, the sliding sleeve 66, which is threaded with the lead screw, makes a linear reciprocating motion under the guidance of the lead screw and the guide rod 63. The sliding sleeve 66 drives the scraper 61 fixed on it to move together. The scraper head 62 at the bottom of the scraper 61 is in close contact with the surface of the base 1. As the scraper 61 moves, the scraper head 62 scrapes away the dirt, debris and other objects on the base 1 and pushes them to one end of the cargo box, completing one cleaning process. When cleaning is required again, the motor 6 can be restarted to make the scraper 61 continue to move for cleaning.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
