[0002] The logistics industry is becoming more and more unmanned, and cage trucks are being used more and more widely in the logistics industry. Currently, logistics vehicles used to transport cage trucks are usually equipped with a flip frame on the vehicle body platform to load the cage truck and realize the automatic loading and unloading function of the cage truck. However, when the flip frame flips down, it is often easy to collide with the rear of the vehicle body. The rear of the vehicle body is equipped with an exterior panel, and it is difficult to arrange an anti-collision structure, so the vehicle cannot be effectively protected. With the increasing degree of unmanned operation in the logistics industry, this method is likely to bring great safety hazards.

[0003] Therefore, a logistics vehicle is urgently needed to solve the above technical problems. Utility Model Content

[0004] Based on the above, the purpose of the utility model is to provide a logistics vehicle that can buffer the collision between the load-bearing frame and the rear part of the vehicle body during the flipping process, provide effective safety protection for the vehicle, and limit the flipping movement of the load-bearing frame to the extreme position, thereby improving the position accuracy of the flipping of the load-bearing frame; at the same time, avoid affecting the appearance of the rear part of the vehicle body.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0014] In some possible implementations, when the supporting frame rotates to the second position, a safety gap is provided between the buffer block and the rear contact edge in a vertical direction to prevent the buffer block from accidentally contacting the rear contact edge.

[0015] In some possible implementations, when the supporting frame rotates to the second position, the buffer block is located above the rear contact edge or the buffer block is located below the rear contact edge.

[0035] like Figures 1 to 6 As shown, the present embodiment provides a logistics vehicle, including a vehicle body 1, wherein the vehicle body 1 includes a chassis platform 11 with a front end arranged at the rear of the front end. A load-bearing frame 2 is movably mounted on the chassis platform 11, and the load-bearing frame 2 may be optionally C-shaped, including a bottom frame, a front support and a rear support, and the inner space of the load-bearing frame 2 is used to load a cargo box 100. The load-bearing frame 2 can also be flipped relative to the chassis platform 11 to realize automatic loading and unloading of the cargo box 100. In the present utility model, the cargo box 100 may be a cage truck, a container, a shelf, etc., and the present embodiment is described by taking a cage truck as an example. A flipping mechanism 3 is also provided on the chassis platform 11 of the present embodiment, and the flipping mechanism 3 is connected to the load-bearing frame 2, and is used to flip the load-bearing frame 2 between a first position and a second position, wherein the first position is the position of the load-bearing frame 2 when it is in a transport state, and the second position is the position of the load-bearing frame 2 when it is in a loading and unloading state. The logistics vehicle of this embodiment also includes a buffer block 4, which is arranged at the bottom of the supporting frame 2 when it is in the first position and close to the rear of the vehicle body 1. When the supporting frame 2 rotates to the second position, the buffer block 4 abuts against the rear of the vehicle body 1. The material of the buffer block 4 of this embodiment can be rubber, plastic, foam, etc., so as to achieve the effect of buffering the collision force. The number of buffer blocks 4 can be one or at least two; when the number of buffer blocks 4 is one, it is preferably arranged in the middle position of the crossbeam of the supporting frame 2; when the number of buffer blocks 4 is at least two, at least two buffer blocks 4 are evenly spaced on the crossbeam of the supporting frame 2 to ensure the force balance of the supporting frame 2.

[0036] In the logistics vehicle provided by this embodiment, when the supporting frame 2 rotates to the second position, the buffer block 4 on the supporting frame 2 abuts against the rear of the vehicle body 1, which can buffer the collision between the supporting frame 2 and the rear of the vehicle body 1 during the flipping process, thus forming an effective safety protection for the vehicle; and the buffer block 4 can limit the flipping movement of the supporting frame 2 to the extreme position, thereby improving the position accuracy of the flipping of the supporting frame 2. In addition, since the buffer block 4 is arranged on the supporting frame 2, the rear of the vehicle body 1 can be manufactured in one piece, and there is no need to add a buffer block 4 at the rear of the vehicle, which results in a hole being opened at the rear of the vehicle or the buffer block 4 being installed outside, resulting in an ugly appearance.

[0037] Specifically, the flipping mechanism 3 of this embodiment includes a translation component and a rotation component. When loading and unloading is required, the load-bearing frame 2 is first driven by the translation component to move a certain distance toward the rear of the vehicle body 1 from the first position, and then the load-bearing frame 2 is driven by the rotation component to flip downward a certain angle to reach the second position. At this time, the opening of the load-bearing frame 2 faces the rear of the vehicle body 1, which is convenient for pushing the cage car into the load-bearing frame 2 or unloading the cage car from the load-bearing frame 2; when the loading and unloading is completed and transportation is required, the load-bearing frame 2 is first driven by the rotation component to flip upward a certain angle from the second position, and then the load-bearing frame 2 is driven by the translation component to move a certain distance toward the front of the vehicle body 1 to reach the first position. At this time, the opening of the load-bearing frame 2 faces the top of the vehicle body 1, which can prevent the cage car from falling out.

[0038] Optionally, in this embodiment, when the load-bearing frame 2 is in the first position, its bottom frame is parallel to the chassis platform 11, so that the cage car can be placed on the load-bearing frame 2 in a horizontal state during transportation, thereby increasing the stability of the cage car transportation; and when the load-bearing frame 2 is in the second position, its bottom frame is perpendicular to the chassis platform 11, at which time the opening of the load-bearing frame 2 faces the rear of the vehicle body 1, the front support is located above the opening, and the rear support is located below the opening, which is convenient for loading and unloading the cage car, and also facilitates the contact between the buffer block 4 and the rear of the vehicle body 1. This embodiment realizes the switching of the load-bearing frame 2 between the horizontal state and the vertical state by rotating the load-bearing frame 2 forward or backward by 90 degrees, which has a reasonable structure and simple operation.

[0039] Furthermore, in this embodiment, a support beam 12 is provided at the rear of the vehicle body 1 to ensure the structural strength and safety of the vehicle body 1; an integrated exterior panel 13 is provided outside the support beam 12, and when the supporting frame 2 rotates to the second position, the buffer block 4 directly abuts against the exterior panel 13 on the back of the support beam 12 to achieve the functions of buffering collision and overturning limit. The exterior panel 13 is preferably manufactured in one piece, and its surface is smooth and flat to ensure the neatness of the entire rear of the vehicle body 1, improve the appearance of the vehicle body 1, and enhance the user experience.

[0040] Optionally, a rear touch edge 5 is also fixed to the rear of the vehicle body 1. The rear touch edge 5 is located at a lower position of the rear of the vehicle body 1 and protrudes outward from the rear of the vehicle body 1, so as to buffer the collision between other structures and the rear of the vehicle, thereby protecting the rear of the vehicle. In this embodiment, the rear touch edge 5 is the structure that protrudes the most outward from the entire rear end of the logistics vehicle, so that the entire rear end of the logistics vehicle from top to bottom is located within the protection range of the rear touch edge 5, avoiding damage to the logistics vehicle due to a collision with the rear of the vehicle. Specifically, the rear touch edge 5 can be a U-shaped anti-collision strip, the two ends of the U-shaped anti-collision strip are respectively connected to the two sides of the vehicle body 1, and the middle area of ​​the U-shaped anti-collision strip is connected to the rear end of the vehicle body 1, so that the rear of the vehicle can be better covered in the rear touch edge 5, thereby improving the protective effect of the rear of the vehicle. The rear touch edge 5 can be selected from elastic plastics, rubber and other materials to improve its buffering effect on impact force.

[0041] In this embodiment, when the supporting frame 2 rotates to the second position, the buffer block 4 on the supporting frame 2 can be located above the rear contact edge 5 or below the rear contact edge 5, which is set according to the actual situation. Further, when the supporting frame 2 rotates to the second position, the buffer block 4 and the rear contact edge 5 should have a certain safety distance in the vertical direction to prevent the buffer block 4 from accidentally touching the rear contact edge 5, avoid interfering with the movement of the supporting frame 2, and ensure that the supporting frame 2 can rotate to the second position smoothly and accurately.

[0042] In order to facilitate the installation of the buffer block 4, the present embodiment is further provided with a buffer block mounting seat 6. Optionally, the buffer block mounting seat 6 is fixed to the supporting frame 2 by welding or screwing, and the buffer block 4 is fixed to the buffer block mounting seat 6 by screwing. Exemplarily, a nut member 61 is fixed inside the buffer block mounting seat 6, a countersunk hole 41 is provided on the buffer block 4, and a bolt 42 passes through the countersunk hole 41 and is threadedly connected to the nut member 61. The above fixing method has a simple structure, convenient installation, and reliable connection. Of course, in other embodiments, the buffer block 4 can also be fixed to the buffer block mounting seat 6 by other methods, which is not limited to the present embodiment.

[0043] Furthermore, a front touch edge 7 is also provided at the front end of the vehicle head. The front touch edge 7 is located at a lower position at the front end of the vehicle head and protrudes outward from the surface of the vehicle head, so as to buffer the collision between other structures and the vehicle head, thereby protecting the vehicle head. In this embodiment, the front touch edge 7 is the structure that protrudes the most outward from the entire front end of the logistics vehicle, so that the entire front end of the logistics vehicle is located within the protection range of the front touch edge 7 from top to bottom, thereby avoiding damage to the logistics vehicle due to a collision with the vehicle head. Specifically, the front touch edge 7 can be a U-shaped anti-collision strip, the two ends of the U-shaped anti-collision strip are respectively connected to the two sides of the vehicle body 1, and the middle area of ​​the U-shaped anti-collision strip is connected to the front end of the vehicle head, so that the vehicle head can be better covered in the front touch edge 7, thereby improving the protection effect on the vehicle head. The front touch edge 7 can be selected from elastic plastics, rubber and other materials to improve its buffering effect on impact force. Furthermore, in this embodiment, the front contact edge 7 and the rear contact edge 5 are both extended in the horizontal direction, and the front contact edge 7 and the rear contact edge 5 are at the same height on the vehicle body 1, thereby improving the consistency of the overall appearance of the logistics vehicle.
