Structurally, they consist of a floor, side panels, and a rear panel. Some also feature a flexibly openable roof. They are made of a variety of materials, with steel being the most common, offering durability and the ability to carry heavier cargo. Aluminum alloy, with its lightweight and corrosion-resistant properties, reduces vehicle weight and improves fuel economy. The volume varies depending on the vehicle model, meeting diverse needs, from daily small-item deliveries to large-scale engineering material transportation.

[0003] Patent application publication number CN221223701U discloses a device for measuring the internal dimensions of a vehicle cargo box, relating to the field of vehicle measurement technology. The device comprises a measuring area disposed on the ground and a measuring device disposed off the ground, the measuring device comprising a first measuring device, a second measuring device, a third measuring device, and a fourth measuring device; the first measuring device and the second measuring device are located in front of and behind the measuring area, and are located on either side of the measuring area, respectively; the fourth measuring device is located above the driving centerline of the measuring area; the third measuring device is disposed between the first and fourth measuring devices and is located on the same side of the second measuring device; the measuring devices are oriented toward the measuring area;

[0004] The above-mentioned patented measuring device can be rotated so that the scanning angle completely covers the measuring area, and is used to measure the internal dimensions of the automobile cargo box. However, in the process of measuring the interior of the cargo box, because the cargo box has different dimensions that need to be measured, the above-mentioned patent uses a laser measurement method which is inefficient. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a device for measuring the internal dimensions of a vehicle cargo box to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for measuring the internal dimensions of a car cargo box, comprising a placement rack, a movable component fixedly connected to the bottom of the placement rack, and a measuring mechanism fixedly connected to the outer wall of the placement rack. The device can be flexibly moved to any position inside the cargo box via the movable component at the bottom of the placement rack, eliminating the need for manual repeated handling of the measuring equipment, significantly shortening the measurement time, being particularly suitable for rapid adaptation of cargo boxes of different sizes, and greatly improving measurement efficiency;

[0007] The measuring mechanism comprises:

[0008] The power component is fixedly connected to the outer wall of the placement frame, and the measuring belt is wound around the placement frame and the driving wheel for multiple turns. Therefore, when measuring the inside of the cargo box, the measuring belt can be pulled to extend the cargo box to measure the cargo box. The gas bin is provided at the end of the measuring belt. The measuring belt can be pulled out by pulling the gas bin, and then the suction cup under the gas bin is attached to the inner wall of the cargo box. In a normal state, the zigzag tube is in a contracted state, and then the bolt is turned to rotate in the threaded seat. The bolt is rotationally connected to the first bearing, so it will not drive the zigzag tube to rotate. When the bolt moves, it will pull the zigzag tube to extend. When the zigzag tube extends, the space inside it increases. When the amount of gas remains unchanged, a negative pressure state is generated inside the gas bin and the zigzag tube, thereby increasing the adsorption of the suction cup to the cargo box.

[0009] A driving wheel is rotatably connected to the outer wall of the power component. After completing measurement of one location, the power component is powered on to start the driving wheel, which retracts the measuring tape and resets the measuring tape. A switch for controlling the start of the power component is provided on the placement rack.

[0010] The measuring belt is sleeved on the outer wall of the driving wheel and the placement frame. The adsorption component at the end of the measuring belt is attached to the inner wall of the cargo box through the suction cup, and the expansion and contraction of the zigzag tube is adjusted by bolts to generate negative pressure adsorption, ensuring that the measuring belt is stably fixed, avoiding operation interruptions caused by manual support, and supporting one-handed operation, further improving measurement efficiency;

[0011] Adsorption component, the outer wall of the measuring tape is fixedly connected to the outer wall of the adsorption component.

[0012] Preferably, a protective cover is fixedly connected to the outer wall of the placement rack at the position of the driving wheel. After the measurement is completed, the power component drives the driving wheel to quickly reel in the measuring tape and reset it without manual recovery. It can seamlessly connect the continuous measurement of different areas in the cargo box, which is especially suitable for quickly obtaining multiple-segment dimensions of complex-structured cargo boxes, effectively shortening the overall measurement cycle.

[0013] Preferably, the adsorption assembly includes a gas chamber, the gas chamber is fixedly connected to the end of the measuring tape, and a suction cup is fixedly connected to the bottom of the gas chamber.

[0014] Preferably, the outer wall of the gas bin is fixedly connected to one end of the zigzag tube, the other end of the zigzag tube is fixedly connected to a first bracket, and the outer wall of the first bracket is rotatably connected to a bolt.

[0015] Preferably, the first bracket is rotatably connected to the bolt through a first bearing, the top of the gas bin is fixedly connected to a threaded seat, the bolt is threadedly connected to the threaded seat, and the suction cup, gas bin and tortuous tube are internally connected.

[0016] Preferably, an auxiliary mechanism is fixedly connected to the top of the placement rack, and the monitoring wheel of the auxiliary mechanism is in contact with the measuring belt, which can automatically detect the moving length of the measuring belt and transmit the data to the monitoring component. The length, width, height and volume of the cargo box are calculated in real time through the built-in program, eliminating manual recording and secondary calculation steps, reducing human errors, and significantly improving data processing efficiency.

[0017] Preferably, the auxiliary mechanism includes a placement plate, which is fixedly connected to the top of the placement rack, and the outer wall of the placement plate is fixedly connected to a second bracket, the outer wall of the second bracket is fixedly connected to a monitoring component, and the outer wall of the monitoring component is fixedly connected to a guide assembly. The monitoring component is electrically connected to the monitoring wheel. When the monitoring wheel is in contact with the measuring belt, the monitoring wheel will drive the rotation of the measuring belt when the measuring belt moves, so that the monitoring wheel can detect the moving length of the measuring belt. The moving length transmits the signal to the monitoring component, which is then displayed and stored by the monitoring component. The monitoring component is programmed to automatically calculate the length of the cargo box when the length, width and height of the car cargo box are obtained.

[0018] Preferably, the guide assembly includes a second bearing, which is fixedly connected to the outer wall of the monitoring component, the bottom of the second bearing is rotatably connected to one end of a bent rod, the other end of the bent rod is rotatably connected to a third bearing, the outer wall of the third bearing is rotatably connected to a monitoring wheel, and a spring is fixedly connected between the monitoring component and the bent rod, the elastic length of the spring is greater than the height of the monitoring component, so that the monitoring wheel is elastically squeezed on the outer wall of the measuring belt, and the monitoring wheel passes through the third bearing and the second bearing respectively, so that the monitoring wheel can rotate.

[0019] The present invention provides a device for measuring the internal dimensions of a vehicle cargo box. It has the following beneficial effects:

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0035] For example 1, please refer to Figure 1-6 The present invention provides a technical solution: a device for measuring the internal dimensions of a car cargo box, comprising a placing rack 1, a moving component 2 is fixedly connected to the bottom of the placing rack 1, and a measuring mechanism 3 is fixedly connected to the outer wall of the placing rack 1;

[0036] A movable part 2 is provided at the bottom of the placement rack 1, which can be moved to a desired position, making it easy to move the placement rack 1 when measuring inside the car cargo box;

[0037] The measuring mechanism 3 includes:

[0038] A power component 31, the power component 31 is fixedly connected to the outer wall of the placement rack 1;

[0039] A driving wheel 34 rotatably connected to the outer wall of the power component 31 ;

[0040] The measuring belt 33 is sleeved on the driving wheel 34 and the outer wall of the placement rack 1. The measuring belt 33 is wound around the placement rack 1 and the driving wheel 34 in multiple turns. Therefore, when measuring the inside of the cargo box, the measuring belt 33 can be pulled to extend the measuring belt 33 to measure the cargo box. The gas chamber 351 is set at the end of the measuring belt 33. The measuring belt 33 can be pulled out by pulling the gas chamber 351. Then the suction cup 352 under the gas chamber 351 is attached to the inner wall of the cargo box. In the normal state, the zigzag tube 353 is in a retracted state. Then, the bolt 356 is turned to rotate it in the threaded seat 357. The bolt 356 is rotatably connected to the first bearing 355, so it will not drive the zigzag tube 353 to rotate.

[0041] The adsorption component 35 , the outer wall of the measuring tape 33 is fixedly connected to the outer wall of the adsorption component 35 .

[0042] A protective cover 32 is fixedly connected to the outer wall of the placement rack 1 at the position of the driving wheel 34.

[0043] The adsorption assembly 35 includes a gas chamber 351, which is fixedly connected to the end of the measuring tape 33. A suction cup 352 is fixedly connected to the bottom of the gas chamber 351. After the measurement of one place is completed, the power component 31 is powered on to drive the driving wheel 34 to rotate. The driving wheel 34 rotates to shrink the measuring tape 33, thereby driving the measuring tape 33 to reset. A switch for controlling the start of the power component 31 is set on the placement rack 1.

[0044] One end of the zigzag tube 353 is fixedly connected to the outer wall of the gas chamber 351 , the other end of the zigzag tube 353 is fixedly connected to the first bracket 354 , and the outer wall of the first bracket 354 is rotatably connected to the bolt 356 .

[0045] The first bracket 354 is rotatably connected to the bolt 356 through the first bearing 355. The top of the gas chamber 351 is fixedly connected to the threaded seat 357. The bolt 356 is threadedly connected to the threaded seat 357. The suction cup 352, the gas chamber 351 and the zigzag tube 353 are internally connected.

[0046] The measuring belt 33 is wound around the placement rack 1 and the driving wheel 34 with multiple turns. Therefore, when measuring the interior of the cargo box, the measuring belt 33 can be pulled to extend the measuring belt 33 to measure the cargo box. The gas chamber 351 is set at the end of the measuring belt 33. The measuring belt 33 can be pulled out by pulling the gas chamber 351. Then the suction cup 352 under the gas chamber 351 is attached to the inner wall of the cargo box. In a normal state, the zigzag tube 353 is in a retracted state. Then, the bolt 356 is turned to rotate it in the threaded seat 357. The bolt 356 is rotationally connected to the first bearing 355, so it will not drive the zigzag tube 353 to rotate. When the bolt 356 moves, it will pull the zigzag tube 353 to extend. When the zigzag tube 353 extends, the space inside it increases. Under the condition that the amount of gas remains unchanged, a negative pressure state is generated inside the gas chamber 351 and the zigzag tube 353, thereby increasing the adsorption of the suction cup 352 to the cargo box.

[0047] After completing the measurement of one place, the power component 31 is powered on to drive the driving wheel 34 to rotate. The driving wheel 34 rotates to shrink the measuring belt 33, thereby driving the measuring belt 33 to reset. A switch for controlling the activation of the power component 31 is provided on the placement rack 1.

[0048] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0049] An auxiliary mechanism 4 is fixedly connected to the top of the placement rack 1 .

[0050] The auxiliary mechanism 4 includes a placement plate 43, which is fixedly connected to the top of the placement rack 1. The outer wall of the placement plate 43 is fixedly connected to the second bracket 42, the outer wall of the second bracket 42 is fixedly connected to the monitoring component 41, and the outer wall of the monitoring component 41 is fixedly connected to the guide assembly 44.

[0051] The guide assembly 44 includes a second bearing 441, which is fixedly connected to the outer wall of the monitoring component 41. The bottom of the second bearing 441 is rotatably connected to one end of a curved rod 442, and the other end of the curved rod 442 is rotatably connected to a third bearing 443. The outer wall of the third bearing 443 is rotatably connected to a monitoring wheel 444. A spring 445 is fixedly connected between the monitoring component 41 and the curved rod 442.

[0052] The monitoring component 41 is electrically connected to the monitoring wheel 444. When the monitoring wheel 444 is in contact with the measuring tape 33, the measuring tape 33 moves, which drives the monitoring wheel 444 to rotate. This allows the monitoring wheel 444 to detect the moving length of the measuring tape 33. The moving length transmits a signal to the monitoring component 41, which then displays and stores the signal. The monitoring component 41 is also programmed to automatically calculate the length of the cargo box when the length, width, and height of the vehicle cargo box are obtained.

[0053] The elastic length of the spring 445 is greater than the height of the monitoring component 41 , so the monitoring wheel 444 is pressed against the outer wall of the measuring belt 33 by the elastic compression of the spring 445 . The monitoring wheel 444 passes through the third bearing 443 and the second bearing 441 , respectively, thereby allowing the monitoring wheel 444 to rotate.

[0054] The program of the monitoring component 41 may be:
