Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation, and in particular to a logistics transportation device with a shock absorbing structure. Background Art

[0002] Logistics is the physical flow of goods from the supply point to the receiving point. According to actual needs, the basic functions of transportation, storage, loading and unloading, handling, packaging, circulation processing, distribution, information processing, etc. are organically combined. Transportation is the activity of using transportation tools to achieve the spatial displacement of passengers or goods.

[0003] In the field of logistics, for some fragile or valuable items, when they are loaded into the logistics box, a buffer component needs to be provided in the logistics box. For example, the Chinese patent with publication number CN107042947A discloses a logistics box structure, in which air bags are respectively provided on the front, rear, left and right side walls of the box body, a groove is provided at the bottom of the box body, a shock-absorbing pad is embedded in the groove, a box cover is installed on the top of the box body, and an upper air bag is provided at the bottom of the box cover.

[0004] In the above patent, the contents are restricted by utilizing the expansion of the airbag during the inflation process, thereby preventing the contents from colliding with the inner wall of the box during the vibration process. However, in the above patent, if the airbag is inflated first and the items are placed in the box later, the airbag will occupy a certain space inside the box after inflation. When the volume of the items is large, this will easily affect the efficiency of placing the items into the box; if the items are placed first and the airbag is inflated later, the airbag needs to be inflated every time after the items are placed in the box, which takes a certain amount of time and affects the efficiency of logistics transportation. Summary of the invention

[0005] The object of the present invention is to provide a logistics transportation device with a shock-absorbing structure to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, a logistics transportation device with a shock-absorbing structure is provided, comprising a box body with an opening at the top, and a plurality of air bags are arranged on each inner wall of the box body; a bearing plate for carrying articles is longitudinally slidably arranged inside the box body, and the bearing plate divides the upper part of the box body into a storage cavity and the lower part into a buffer cavity; wherein the air bag is located in the storage cavity; a shock-absorbing component and an inflation mechanism are arranged in the buffer cavity; the top of the shock-absorbing component is connected to the bottom of the bearing plate, and when the article is driven by external force to move longitudinally in the box body, the shock-absorbing component cushions the bearing plate; the inflation mechanism is connected to the plurality of air bags, and inflates the air bags by the force of the longitudinal movement of the bearing plate;

[0008] When the box is in a transport state, the support adjustment component drives the shock absorbing component and the supporting plate to move downward, and controls the valve assembly to be in a closed state, so that the inflation mechanism can preferentially deliver gas to the airbags without valve assemblies during the downward movement of the supporting plate, so as to provide preliminary protection for the articles through some of the airbags; when the box is in a placement state, the support adjustment component controls the valve assembly to be in an open state, so that the inflation mechanism can inflate all the airbags.

[0009] As a further improvement of the technical solution, air bags without valve components are distributed on each inner wall of the box.

[0010] As a further improvement of the technical solution, the support adjustment component includes a support column that slides longitudinally through the bottom of the box body, and the top end of the support column is connected to the bottom of the shock absorbing component.

[0011] As a further improvement of the technical solution, the shock absorbing component includes a damper whose top end is fixedly connected to the bearing plate and whose bottom end is fixedly connected to the support column, and the outer sleeve of the damper is provided with a spring located between the bearing plate and the support column.

[0012] As a further improvement of the technical solution, the shock absorbing component is an elastic pad whose top end is connected to the bottom of the bearing plate and whose bottom end is connected to the top of the support column.

[0013] As a further improvement of the present technical solution, the bottom ends of the multiple air bags are connected with air intake pipes. After the bottom ends of the multiple air intake pipes penetrate into the buffer cavity, they are commonly connected with an air collecting box fixedly arranged in the buffer cavity; each of the air intake pipes is provided with a one-way air supply valve for conveying the gas in the air collecting box to the air bag; the top of the air bag has an air vent, and a plug is provided in the air vent.

[0014] As a further improvement of the present technical solution, the inflation mechanism includes a piston cylinder fixedly arranged on the inner wall of the bottom of the box body, and a piston plate longitudinally slidably arranged in the piston cylinder, and the piston plate is fixedly arranged at the bottom of the supporting plate; an air supply pipe connecting the piston cylinder and the air collecting box is arranged between the two, and a one-way exhaust valve for conveying the gas in the piston cylinder to the air collecting box is arranged in the air supply pipe; the outer ring of the piston cylinder is connected to a one-way intake valve for allowing external gas to enter the piston cylinder, and a pressure relief valve for releasing the gas in the piston cylinder.

[0015] As a further improvement of the present technical solution, the valve assembly includes a convex tube connected to a portion of the outer ring of the intake pipe, a plug rod that can be inserted into the intake pipe is longitudinally slidably arranged in the convex tube, and the tops of the multiple plug rods are commonly fixedly connected to an elastic rod, and the end of the elastic rod is fixedly connected to the top of the support column.

[0016] As a further improvement of the present technical solution, the support column includes a slide cylinder with a socket on the top, and a column inserted into the socket at the bottom, the slide cylinder slides longitudinally through the bottom of the box, and the top of the column is connected to the bottom of the shock-absorbing component; the top of the slide cylinder is fixedly connected to the end of the elastic rod; and there is friction between the column and the socket, and the friction is greater than the downward pressure exerted on the column by the weight of the object itself; when the bottom end of the column contacts the bottom end of the socket, the bottom end of the rod extends to the middle position in the air inlet pipe to reduce the gas flow in the corresponding air inlet pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the logistics transportation device with a shock-absorbing structure, a plurality of small airbags are arranged on the inner wall of the box. When the box is in a transport state, the suspended characteristics of the transport state are used to inflate some of the airbags, so that the partially inflated airbags can provide preliminary protection for the items. Then, during the transportation process, the vibration of the vehicle is used to inflate the remaining airbags, thereby not affecting the placement of larger items. At the same time, the airbags are automatically inflated to improve the efficiency of logistics transportation.

[0019] 2. In the logistics transportation device with a shock-absorbing structure, the insertion column can move downward by utilizing the inertial force of the articles when the transport vehicle travels on a bumpy road section, so that the insertion rod moves down into the air intake pipe and partially blocks the air intake pipe, so that most of the gas in the air collecting box enters the airbag without a valve assembly at the first time, causing this part of the airbag to expand quickly, thereby avoiding collision between the airbag and the inner wall of the box caused by large shaking.

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] like Figure 1 As shown, a logistics transport device with a shock-absorbing structure is provided, including a box 100. The box 100 is roughly a square structure, and has an opening on the top for items to enter the box 100. At the same time, a box cover 101 is also provided at the opening, which can be used to seal the opening on the top of the box 100. In addition, buckle grooves are provided in the middle and upper parts of the opposite sides of the box 100. When the box 100 needs to be carried, the box 100 can be lifted by putting hands into the buckle grooves, so that the box 100 is in a suspended state. At the same time, as Figure 2 As shown, a plurality of airbags 120 are disposed on each inner wall of the box 100 . When the plurality of airbags 120 are inflated, the airbags 120 can protect the items in the box 100 .

[0043] However, if the airbag 120 is inflated first and the items are placed in the box 100 later, the airbag 120 will occupy a certain space inside the box 100 after being inflated. When the volume of the items is large, this will easily affect the efficiency of placing the items into the box 100; if the items are placed in the box first and the airbag 120 is inflated later, then since the airbag 120 needs to be inflated every time after the items are placed in the box 100, it will take a certain amount of time and affect the efficiency of logistics transportation.

[0044] In view of this, Figure 2 In the embodiment, a carrying plate 110 for carrying articles is longitudinally slidably arranged inside the box body 100, and the carrying plate 110 divides the upper part of the box body 100 into a storage cavity 111 and the lower part into a buffer cavity 112; wherein, an airbag 120 is located in the storage cavity 111; a shock absorbing component 130 and an inflating mechanism 140 are arranged in the buffer cavity 112; the top of the shock absorbing component 130 is connected to the bottom of the carrying plate 110, and when the articles are driven by external forces to move longitudinally in the box body 100, the shock absorbing component 130 buffers the carrying plate 110; the inflating mechanism 140 is connected to a plurality of airbags 120, and inflates the airbags 120 by the force of the longitudinal movement of the carrying plate 110;

[0045] The logistics transport device also includes a valve assembly and a support and adjustment component 150 connected to the valve assembly; the top of the support and adjustment component 150 is connected to the top of the shock absorbing component 130, and the bottom longitudinally slides through the bottom of the box body 100; the valve assembly is arranged at the connection between the partial inflation mechanism 140 and the airbag 120;

[0046] When the box body 100 is in a transport state, the support and adjustment component 150 drives the shock absorbing component 130 and the supporting plate 110 to move downward, and controls the valve assembly to a closed state, so that the inflation mechanism 140 can preferentially deliver gas to the airbags 120 without valve assemblies during the downward movement of the supporting plate 110, so as to provide preliminary protection for the articles through some of the airbags 120; when the box body 100 is in a placement state, the support and adjustment component 150 controls the valve assembly to an open state, so that the inflation mechanism 140 can inflate all the airbags 120.

[0047] That is to say, by arranging multiple small airbags 120 on the inner wall of the box 100, when the box 100 is in a transport state, the suspended characteristics of the transport state are utilized to inflate some of the airbags 120, so that the partially inflated airbags 120 can provide preliminary protection for the items, and then during transportation, the vibration of the vehicle is utilized to inflate the remaining airbags 120, thereby not affecting the placement of larger items. At the same time, automatic inflation of the airbags 120 is achieved, thereby improving the efficiency of logistics transportation.

[0048] In the above, the outer ring of the carrier plate 110 is preferably slidably fitted with the inner wall of the box body 100, so that the garbage in the storage cavity 111 can be prevented from falling into the buffer cavity 112 through the gap between the carrier plate 110 and the box body 100. At the same time, the airbags 120 without valve components are distributed on each inner wall of the box body 100, and each inner wall has at least one airbag 120 without valve components, so that when the airbags 120 without valve components are inflated first, all-round preliminary protection can be provided for the surroundings of the items.

[0049] Figure 3 The specific structure of the support and adjustment component 150 is shown. As shown in the figure, the support and adjustment component 150 includes a support column 151 that slides longitudinally through the bottom of the box 100, and the top of the support column 151 is connected to the bottom of the shock absorbing component 130. When the box 100 is in a suspended state, the support column 151 will be subjected to the downward pressure of the object, the bearing plate 110 and the spring 131, and thus forced to move downward; when the support column 151 moves downward, the height of the spring 131, the bearing plate 110 and the object is also reduced, so that the bearing plate 110 drives the inflation mechanism 140 to operate.

[0050] During the logistics transportation process, since the road cannot be guaranteed to be continuously flat, the logistics vehicle will inevitably vibrate during driving. When vibration occurs, the vibration force will be transmitted to the items through the box 100, causing the items to shake on the top of the supporting plate 110. In order to avoid a hard collision between the items and the supporting plate 110, in the present invention, a shock absorbing component 130 is provided at the bottom of the supporting plate 110. When the items are driven by external forces to move the box 100 longitudinally, the shock absorbing component 130 can cushion the supporting plate 110. Next, Figure 3 An embodiment of the shock absorbing component 130 is shown, as shown in the figure:

[0051] The shock absorbing component 130 includes a damper whose top end is fixedly connected to the carrier plate 110 and whose bottom end is fixedly connected to the support column 151, and the outer sleeve of the damper is provided with a spring 131 located between the carrier plate 110 and the support column 151. When the carrier plate 110 is subjected to downward pressure from an object, the spring 131 begins to compress, and at the same time, the damper also begins to contract, thereby achieving buffering of the object. When the object moves upward, the spring 131 rebounds and drives the damper to extend, so as to push the carrier plate 110 to reset. The function of the damper is to prevent the spring 131 from rebounding frequently.

[0052] It should be noted that the shock absorbing component 130 composed of the damper and the spring 131 has been used in existing products, such as automobiles, motorcycles, electric vehicles, etc., so it will not be described in detail here.

[0053] Figure 4 Another embodiment of the shock absorbing component 130 is shown in the figure: the shock absorbing component 130 is an elastic pad 132 whose top end is connected to the bottom of the carrier plate 110 and whose bottom end is connected to the top of the support column 151. The elastic pad 132 is preferably made of a flexible material such as rubber, sponge, foam, etc. In this way, when the carrier plate 110 is subjected to downward pressure from an object, the elastic pad 132 will compress itself, thereby buffering the carrier plate 110.

[0054] like Figure 2 and Figure 5As shown, the bottom ends of the multiple air bags 120 are connected to the air inlet pipe 121. After the bottom ends of the multiple air inlet pipes 121 penetrate into the buffer cavity 112, they are connected to the air collecting box 122 fixedly arranged in the buffer cavity 112. Figure 7 As shown, each air inlet pipe 121 is provided with a one-way air supply valve 123 for conveying the gas in the air collecting box 122 to the airbag 120; the top of the airbag 120 has an air vent hole, and a plug 124 is provided in the air vent hole. When the gas in the airbag 120 needs to be discharged, the plug 124 can be removed from the air vent hole.

[0055] Figure 5 The distribution position of the inflation mechanism 140 is shown. As shown in the figure, there are multiple inflation mechanisms 140, and the multiple inflation mechanisms 140 are distributed at the four corners of the air collecting box 122. The multiple inflation mechanisms 140 can increase the inflation amount of the airbag 120 during a single downward movement of the carrying plate 110. At the same time, Figure 6 The specific structure of the inflation mechanism 140 is shown. As shown in the figure, the inflation mechanism 140 includes a piston cylinder 141 fixedly arranged on the inner wall of the bottom of the box body 100, and a piston plate 142 longitudinally slidably arranged in the piston cylinder 141, and the piston plate 142 is fixedly arranged at the bottom of the supporting plate 110; an air supply pipe 143 is arranged between the piston cylinder 141 and the air collecting box 122 to connect the two, and a one-way exhaust valve 144 is arranged in the air supply pipe 143 for conveying the gas in the piston cylinder 141 to the air collecting box 122; the outer ring of the piston cylinder 141 is connected to a one-way intake valve 145 for allowing external gas to enter the piston cylinder 141, and a pressure relief valve 146 for discharging the high-pressure gas in the piston cylinder 141.

[0056] like Figure 8 and Fig. 9 As shown, the valve assembly includes a convex tube 160 connected to the upper part of the outer circle of a part of the air inlet pipe 121, and a plug rod 161 that can be inserted into the air inlet pipe 121 is longitudinally slidably arranged in the convex tube 160, and the tops of multiple plug rods 161 are fixedly connected with an elastic rod 162, and the end of the elastic rod 162 is fixedly connected to the top of the support column 151.

[0057] by Figure 8For example, there are five airbags 120 in the figure, and the bottom of each airbag 120 is connected to the air inlet pipe 121. Among the five air inlet pipes 121, four of the air inlet pipes 121 are provided with valve assemblies, and the other one is not provided with a valve assembly. Therefore, the corresponding airbag 120 without a valve assembly is always connected to the gas collecting box 122; when the box body 100 is suspended in the air, the supporting plate 110 moves downward to drive the inflation mechanism 140 to transport gas to the gas collecting box 122, and the gas entering the gas collecting box 122 enters the corresponding airbag 120 through the air inlet pipe 121 without a valve assembly, so that the corresponding airbag 120 without a valve assembly is inflated first, thereby achieving preliminary protection for the object.

[0058] Combination Fig.11 and Fig.12 As shown, the working principle of the present invention is as follows:

[0059] First, put the object on the top of the carrying plate 110, and the weight of the object acts on the carrying plate 110, the shock absorbing component 130 and the support column 151;

[0060] Fig.12 The schematic diagram of the box 100 in the transport state is shown, in which the box 100 is in a suspended state, and there is no support at the bottom of the support column 151 to support the support column 151, so the support column 151 will move downward under the weight of the items, and at this time, the support column 151 moves downward and protrudes from the bottom of the box 100; during the downward movement, the support column 151 moves downward and drives the insertion rod 161 to move downward through the elastic rod 162, and the insertion rod 161 moves downward into the air inlet pipe 121 and blocks the air inlet pipe 121; when the insertion rod 161 enters the air inlet pipe 121 and blocks the air inlet pipe 121, the elastic rod 162 moves downward through its own elasticity. The support column 151 bends and deforms, so that the support column 151 can continue to move downward. During the downward movement, the support column 151 will also drive the shock absorbing component 130 and the bearing plate 110 to move downward. The bearing plate 110 moves downward to press the piston plate 142 downward. The piston plate 142 moves downward to press the gas in the piston cylinder 141 into the gas collecting box 122 through the gas delivery pipe 143. The gas entering the gas collecting box 122 will enter the intake pipe 121. Since a part of the intake pipe 121 is not provided with a valve assembly, the gas in the corresponding intake pipe 121 without a valve assembly can directly enter the airbag 120 to inflate the airbag 120. This is to provide preliminary protection for the items and prevent the items from colliding with the inner wall of the box 100.

[0061] Since only a single inflation can be performed during transportation, the amount of inflation of the airbag 120 is small, so it is difficult to ensure continuous protection of the items during long-term transportation. Fig.11The schematic diagram of the box 100 in the placed state is shown. In the figure, the bottom end of the support column 151 is blocked by the bottom of the car, so the support column 151 can only move upward and slide into the box 100. The support column 151 moves upward and drives the elastic rod 162 to move upward, and the elastic rod 162 moves upward and drives the plug rod 161 to move upward and disengage from the air intake pipe 121. At this time, the blocked air intake pipe 121 returns to the open state. Then, when the transport vehicle vibrates and causes the items to shake, the shaking items press the carrier plate 110 to move downward, and the carrier plate 110 moves downward to press the piston plate 142 to move downward. The piston plate 142 moves downward to press the gas in the piston cylinder 141 into the gas collecting box 122, and then the gas is transported to all the air bags 120 through the gas collecting box 122, so that the multiple air bags 120 located on the inner wall of the box 100 are all inflated, thereby achieving continuous protection.

[0062] When the airbag 120 is filled with gas, the gas in the piston cylinder 141 can no longer be transported into the airbag 120. When the supporting plate 110 presses the piston plate 142 downward again, the gas in the piston cylinder 141 cannot flow. Therefore, the internal air pressure of the piston cylinder 141 increases, thereby forcing the pressure relief valve 146 to open, allowing the gas in the piston cylinder 141 to be discharged through the pressure relief valve 146.

[0063] Not only that, Fig.10 The structure of the support column 151 is further optimized. As shown in the figure, the support column 151 includes a slide 152 with a socket on the top, and a column 153 inserted into the socket at the bottom. The slide 152 slides longitudinally through the bottom of the box 100, and the top of the column 153 is connected to the bottom of the shock-absorbing component 130; the top of the slide 152 is fixedly connected to the end of the elastic rod 162; and there is friction between the column 153 and the socket, and the friction is greater than the downward pressure exerted on the column 153 by the weight of the object itself; when the bottom end of the column 153 contacts the bottom end of the socket, the bottom end of the rod 161 extends to the middle position in the air inlet pipe 121 (for example, one half, two thirds) to reduce the gas flow in the corresponding air inlet pipe 121.

[0064] Working principle:

[0065] Combination Fig.13As shown, under normal conditions, since the friction between the plug post 153 and the socket is greater than the downward pressure exerted on the plug post 153 by the weight of the object itself, the plug post 153 will not slide to the bottom of the socket. When the transport vehicle travels to a bumpy road section, the vehicle will vibrate greatly, causing the objects in the box 100 to increase the downward pressure on the load-bearing plate 110 due to inertia. At this time, the downward pressure exerted by the objects on the box 100 overcomes the friction between the plug post 153 and the socket, forcing the bottom end of the plug post 153 to slide into the bottom of the socket. At this time, the height of the plug post 153 is reduced, and the plug post 153 will also drive the elastic rod 162 downward during the downward movement. The downward movement of the elastic rod 162 drives the plug post 161 downward to the middle position inside the air intake pipe 121 (such as Fig.13 As shown), the flow rate of the gas in the corresponding air inlet pipe 121 is reduced. At this time, the gas in the air collecting box 122 will preferentially flow into the air inlet pipe 121 without the valve assembly, so that the corresponding airbag 120 without the valve assembly is rapidly inflated, thereby improving the protection efficiency of the object.

[0066] That is to say, when the transport vehicle travels to a bumpy section of the road, the insertion column 153 can use the inertial force of the object to move downward, so that the insertion rod 161 moves down into the air intake pipe 121, partially blocking the air intake pipe 121, so that most of the gas in the air collecting box 122 can enter the air bag 120 without a valve assembly at the first time, so that this part of the air bag 120 can expand quickly, avoiding the collision between the air bag 120 and the inner wall of the box body 100 caused by large shaking.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
