Since it is a prior art, it will not be described in detail in this case. The interior of the delivery box 2 is provided with a support The support assembly can prevent the takeout inside the delivery box 2 from tipping over. The delivery box 2 is provided with a buffer assembly inside. The delivery box 2 is provided with a deceleration assembly inside. The deceleration assembly and the buffer assembly can reduce the frequency and amplitude of the takeout shaking inside the delivery box 2. The buffer assembly includes a slide plate 61. The lower surface of the slide plate 61 is fixedly connected to a connecting block 66. When the slide plate 61 moves, it will drive the connecting block 66 to move synchronously. The inner wall of the left side of the delivery box 2 is fixedly connected to a support rod 62. The inner wall of the delivery box 2 is elastically connected to a slider 64 through a compression spring 63. The upper surface of the slider 64 is hinged with a connecting rod 65. When the slider 64 moves, it will squeeze the connecting rod 65. After being squeezed, the connecting rod 65 will rotate. There are two groups of sliders 64, connecting rods 65, and compression springs 63, which are symmetrically distributed about the center line of the delivery box 2.
[0032] Reference Figure 2 , Figure 5 The upper surface of the connecting rod 65 is hinged on the lower surface of the connecting block 66. The rotating connecting rod 65 will drive the connecting block 66 to move up and down. One end of the compression spring 63 is fixedly connected to the inner wall of the left side of the delivery box 2, and the other end of the compression spring 63 is fixedly connected to the left surface of the slider 64. When the slider 64 moves to the left, it will squeeze the compression spring 63 to generate a reaction force, and when the slider 64 moves, the force area will increase, thereby reducing the impact force caused by road bumps, so as to play a buffering role. The slider 64 is slidably connected to the outer wall of the support rod 62, and the slider 64 slides left and right along the outer wall of the support rod 62. The slide plate 61 is slidably connected to the inner wall of the delivery box 2, and the slide plate 61 slides up and down along the inner wall of the delivery box 2.
[0033] Reference Figure 3 - Figure 4 The deceleration assembly includes a hollow tube 71, the inner wall of the hollow tube 71 is elastically connected to a rubber block 73 through a connecting spring 74, the upper surface of the rubber block 73 is fixedly connected to a round rod 72, and the upper surface of the rubber block 73 is provided with a round hole 701, and the aperture of the round hole 701 is small, which can limit the flow rate of air.
[0034] Reference Figure 3 - Figure 4 The rubber block 73 is made of rubber. The lower surface of the hollow tube 71 is fixedly connected to the inner wall of the bottom end of the delivery box 2. The upper surface of the round rod 72 is fixedly connected to the lower surface of the slide plate 61. When the slide plate 61 moves longitudinally, it will drive the round rod 72 to move synchronously. The rubber block 73 piston is connected to the inner wall of the hollow tube 71. When the rubber block 73 moves downward, it will squeeze the air inside the hollow tube 71. The air inside the hollow tube 71 will be squeezed out from the circular hole 701. When the rubber block 73 moves upward, the external air will be sucked into the interior of the hollow tube 71 from the circular hole 701. Since the aperture of the circular hole 701 is small, the air flow rate will be limited, so the circulation speed can be slowed down, and the buffering effect can be further enhanced. One end of the connecting spring 74 is fixedly connected to the lower surface of the rubber block 73, and the other end of the connecting spring 74 is fixedly connected to the inner wall of the bottom end of the hollow tube 71. When the rubber block 73 moves downward, it will squeeze the connecting spring 74 to generate a reaction force. When the rubber block 73 moves upward, it will stretch the connecting spring 74 to generate a reaction force.
[0035] Reference Figure 2 and Figure 5 The supporting assembly includes a slide bar 81, the inner wall of the slide bar 81 is elastically connected to the limit block 82 through a limit spring 84, and the right surface of the limit block 82 is fixedly connected to the limit rod 83. When the limit rod 83 moves, it will drive the limit block 82 to move synchronously. A limit groove 801 is provided on the inner wall of the front side of the delivery box 2, and the slide bar 81 is slidably connected to the inner wall of the delivery box 2. The slide bar 81 slides left and right along the inner wall of the delivery box 2. The limit rod 83 penetrates and is slidably connected to the right surface of the slide bar 81 for easy grasping. One end of the limit spring 84 is fixedly connected to the rear surface of the limit block 82, and the other end of the limit spring 84 is fixedly connected to the inner wall of the rear side of the slide bar 81. When the limit block 82 moves backward, it will squeeze the limit spring 84 to generate a reaction force. The limit block 82 is plugged into the inner wall of the limit groove 801, which can limit the slide bar 81. There are multiple groups of limit grooves 801, which are evenly distributed on the inner wall of the front side of the delivery box 2.
[0036] Working principle: When in use, first put the takeaway into the delivery box 2, then move the limit rod 83 backward to drive the limit block 82 to move backward, and the limit block 82 moving backward will squeeze the limit spring 84 to generate a reaction force, and the limit block 82 moving backward will also disengage from the limit groove 801 to release the limit on the slide bar 81. After the limit is released, move the slide bar 81 laterally so that the slide bar 81 contacts the takeaway and supports the takeaway, and then release the limit rod 83. The reaction force of the limit spring 84 will push the limit block 82 and the limit rod 83 to move forward, and the limit block 82 moving forward will be plugged into another limit groove 801 to limit the slide bar 81, which can ensure that the slide bar 81 does not slide and ensure the stability of the support for the takeaway.
[0037] Then, grasp the handle 4 to close the box cover 3, and lock the buckle 5 to fix the box cover 3 on the delivery box 2. After the box cover 3 is closed, start the delivery vehicle 1 to start the delivery work. During the delivery process, some sections may be bumpy. When driving on such sections, the delivery box 2 will be bumpy. The impact force generated by the bumping of the delivery box 2 will be transmitted to the slide plate 61, and the slide plate 61 will move longitudinally and drive the takeaway to move longitudinally. When the slide plate 61 moves longitudinally, it will drive the connecting block 66 and the round rod 72 to move synchronously.
[0038] The moving connecting block 66 will drive the connecting rod 65 to rotate, and the rotating connecting rod 65 will drive the slider 64 to move laterally. The laterally moving slider 64 will squeeze or stretch the compression spring 63 to generate a reaction force. The reaction force of the compression spring 63 can slow down the movement speed and displacement distance of the slider 64, thereby slowing down the frequency and amplitude of the shaking of the slider 61, and the moving slider 64 will expand the force area, thereby slowing down the frequency and amplitude of the shaking of the slider 61.
[0039] The moving round rod 72 will drive the rubber block 73 to move longitudinally. When the rubber block 73 moves, it will stretch or squeeze the connecting spring 74 to generate a reaction force, and will allow the external air and the air inside the hollow tube 71 to circulate. The air can only circulate through the round hole 701. Since the round hole 701 has a small aperture, the circulation speed can be slowed down, so the speed and amplitude of the up and down movement of the round rod 72 can be slowed down, so the frequency and amplitude of the shaking of the slide plate 61 can be further slowed down. The slide plate 61 is buffered, and the shaking of the takeaway above the slide plate 61 will also be weakened, so the takeaway is not easy to splash out, which can ensure the stability during delivery. When arriving at the destination, just unlock the buckle 5, open the box cover 3 and take out the takeaway.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
