[0027] The following is a detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-10 As shown, in some illustrative embodiments, a truck with a detachable body is provided, comprising: a truck chassis 1 and an exchange box 2 .

[0029] The exchange box 2 includes: a box body 21, a container corner piece 22, and a flip leg 23. The box body 21 is used to load goods; the container corner piece 22 is arranged at the bottom of the box body 21, and is used to be locked and connected with the truck chassis 1. There are four flip legs 23, which are hinged on the box body 21 and can swing on the box body 21. When the exchange box 2 needs to be removed, the flip legs 23 are opened to make them perpendicular to the ground and fixed, that is, the flip legs 23 cannot swing and return to the storage state. The fixing method can adopt any existing mechanical structure that can achieve that two parts cannot move relative to each other.

[0030] The truck chassis 1 includes a main frame 14 , a sub-frame and an air suspension 15 .

[0031] The main frame 14 is connected to the air suspension 15, and the air suspension 15 is the suspension system of the truck. The main frame 14 is lifted and lowered by the inflation and deflation functions of the air suspension 15, thereby realizing the rising and falling of the truck chassis 1. When rising, it can be docked with the exchange box 2, and when descending, the exchange box 2 can be separated from the truck chassis 1.

[0032] The sub-frame is arranged on the main frame 14, the exchange box 2 is located above the sub-frame, and a rotary lock 111 for locking the container corner fitting 22 is arranged on the sub-frame. In this embodiment, the rotary lock 111 is used in conjunction with the container corner fitting 22 to achieve locking between the truck chassis 1 and the exchange box 2, and the existing rotary lock device can be used. Specifically, the sub-frame is composed of a front sub-frame 11 and a plurality of rear sub-frames 13 arranged in sequence along the longitudinal direction of the main frame 14. Further, the number of the rear sub-frames 13 is three, and the three rear sub-frames 13 are arranged at equal intervals behind the front sub-frame 11 to ensure stable support for the exchange box 2.

[0033] The upper surfaces of the front subframe 11 and the rear subframe 13 are both provided with limiting round pins 115 for positioning the box body 21. The bottom of the box body 21 can be provided with pin holes consistent with the distribution positions of the limiting round pins 115. When the truck chassis 1 rises, the limiting round pins 115 are embedded in the pin holes at the bottom of the box body 21, which not only facilitates the accurate docking of the truck chassis 1 and the exchange box 2, but also further ensures that the box body 21 cannot be displaced, thereby sharing the force of the rotary lock 111.

[0034] The front subframe 11 includes: a crossbeam 112, a longitudinal beam assembly, a fixing frame 117 and a limiting frame 114. The longitudinal beam assembly includes: two front longitudinal beams 113 and two rear longitudinal beams 116.

[0035] The main frame 14 includes a symmetrically arranged left longitudinal beam 141 and a right longitudinal beam 142. The cross beam 112 is perpendicular to the main frame 14, specifically perpendicular to the left longitudinal beam 141 and the right longitudinal beam 142 in the main frame 14, and rotary locks 111 are arranged at both ends of the cross beam 112. A limiting round pin 115 is arranged on the upper surface of the cross beam 112.

[0036] Two front longitudinal beams 113 are arranged on the front side of the cross beam 112 and are perpendicular to the cross beam 112. The spacing between the two front longitudinal beams 113 is consistent with the spacing between the left longitudinal beam 141 and the right longitudinal beam 142 in the main frame 14. Two rear longitudinal beams 116 are arranged on the rear side of the cross beam 112 and are perpendicular to the cross beam 112. After the front sub-frame 11 is installed, the longitudinal beam assembly is located on the top of the main frame 14. The above structural design makes the front sub-frame 11 consist of two cross structures, which matches the structure of the main frame 14 and can ensure the stability of the support.

[0037] A fixing frame 117 is provided on both sides of the front longitudinal beam 113 and the rear longitudinal beam 116. The fixing frame 117 is provided with a first circular hole 1171 for use with the U-bolt 12, that is, the U-bolt 12 passes through the first circular hole 1171 at both ends after passing around the main frame 14 and is fastened with a nut, thereby fixing the front end sub-frame 11 on the top of the main frame 14, with a stable connection and a reliable installation method.

[0038] The limiting frame 114 is disposed on the upper surface of the front longitudinal beam 113 and is used to limit the exchange box 2 .

[0039] The rear sub-frame 13 includes a support beam 135 and a mounting plate 131 disposed at the bottom of the support beam 135. The support beam 135 is perpendicular to the main frame 14, specifically, perpendicular to the left longitudinal beam 141 and the right longitudinal beam 142 in the main frame 14, and a rotary lock 111 is disposed at both ends of the support beam 135, and a limiting round pin 115 is disposed on the upper surface of the support beam 135.

[0040] A plurality of second circular holes 1311 are provided on the mounting plate 131, and the mounting plate 131 is fixed to the outer side surface of the main frame 14 by means of bolts, that is, the bolts are passed through the standard holes and the second circular holes 1311 on the left longitudinal beam 141 or the right longitudinal beam 142 and then are tightened by nuts, thereby fixing the rear end sub-frame 13 to the top of the main frame 14, with stable connection and reliable installation.

[0041] The specific steps of using the detachable cargo truck of this embodiment include:

[0042] Step 1: After the truck delivers the exchange box 2 filled with goods to the destination, the four flip legs 23 installed at the bottom of the exchange box 2 are pulled out and opened and supported on the ground, and then the rotary lock 111 is opened to release the container corner piece 22;

[0043] Step 2: Deflate the airbag in the air suspension 15 to lower the ground clearance of the truck chassis 1. After the deflation operation is completed, slowly move the truck chassis 1 forward.

[0044] Step 3: At this time, another exchange box 2 at the destination is already full of goods and the four flip legs 23 are already on the ground. The truck chassis 1 is driven to the front of this exchange box 2, and the truck chassis 1 is reversed to the bottom of this exchange box 2 by slowly reversing. In this process, when it is detected that this exchange box 2 touches the limit frame 114, the air suspension 15 can be inflated to increase the height of the truck chassis 1 from the ground until the upper plane of the rotary lock 111 is combined with the lower plane of the container corner piece 22 in this exchange box 2. Then tighten the rotary lock 111, retract the flip legs 23, and the truck chassis 1 can carry this exchange box 2 back to the departure place or drive to the new destination. The logistics workers will then organize the unloading of the original exchange box left at the destination.

[0045] The main transportation scenario of the truck with a detachable body in this embodiment is the express logistics transportation industry. The structural design of the truck can realize box-free transportation, which greatly improves the scope of use and efficiency of the vehicle. Through this new mode of transportation, the loading and unloading time during transportation can be reduced to meet customer needs.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
