Description

Technical Field

[0001] This application relates to the field of unmanned vessel transportation technology, and more specifically, to a foam packaging box for unmanned vessels. Background Technology

[0002] Foam boxes are boxes made of foam plastic, which are lightweight, provide insulation, cushioning, are inexpensive, and easy to mold. Foam boxes are used for products that require refrigeration, such as food and beverages, and can also be used for transporting electronic products, such as small household appliances.

[0003] Current foam packaging boxes are equipped with handles and wheels. When moving the box, pulling the handle at the front causes the wheels at the rear to roll on the ground, facilitating movement. However, since the handles and wheels are directly attached to the box, the pulling force on the handles and the impact on the wheels during long-distance movement can easily cause them to detach, making the foam packaging box fragile and difficult to move. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of the prior art by providing an unmanned vessel foam packaging box, thereby solving the problem that the handles and wheels on the foam packaging box are prone to detachment during long-distance transportation.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:

[0006] In one aspect of this application, a foam packaging box for an unmanned surface vessel (USV) is provided, comprising an upper box and a lower box that are fastened together to form a receiving cavity. The receiving cavity is used to receive the USV. On opposite sides of the lower box, a handle insert and a roller insert are respectively provided and embedded in the side wall of the lower box. The handle passes through the outer wall of the lower box and is connected to the handle insert. The roller insert has a mounting shaft extending to the outside of the lower box, and a roller is detachably connected to the mounting shaft.

[0007] Optionally, the handle insert includes a first plate and a second plate fixed to opposite sides of the first plate. The surface of the first plate is parallel or approximately parallel to the surface of the side wall where the handle insert is located, and the surface of the second plate extends along the thickness direction of the side wall where the handle insert is located.

[0008] Optionally, the roller insert also includes a fixing plate and a fixing shaft embedded in the side wall of the lower housing. The fixing shaft is located on the side of the fixing plate near the receiving cavity, and the fixing shaft contacts the plate surface of the fixing plate. One end of the mounting shaft is fixedly connected to the fixing shaft.

[0009] Optionally, the fixing plate includes a third plate and a fourth plate whose surfaces intersect and are connected to each other. The third plate and the fourth plate are respectively located in adjacent side walls of the lower housing, and the fixing shaft is located at the connection between the third plate and the fourth plate.

[0010] Optionally, there are two roller inserts, and a housing reinforcement insert is also embedded in the side wall of the lower housing, with the housing reinforcement insert located between the two roller inserts.

[0011] Optionally, the handle insert, roller insert, and housing reinforcement insert are all evenly distributed with multiple through holes, and the lower housing has a filling portion that fills into the through holes.

[0012] Optionally, a clearance hole is provided on the bottom wall of the lower box body to avoid the propulsion of the unmanned vessel.

[0013] Optionally, the accommodating cavity includes a first trough, a second trough, and a third trough located in the lower housing. The second trough and the third trough are distributed on both sides of the first trough. The first trough is used to accommodate the unmanned vessel, and the second trough and the third trough are used to accommodate the rollers, respectively.

[0014] Optionally, the housing also includes a fourth and a fifth slot located in the lower housing, which are used to accommodate the remote control and the tool and accessory kit, respectively.

[0015] Optionally, the housing also includes a sixth compartment located in the upper housing, in which a frame for carrying the unmanned vessel is provided.

[0016] The beneficial effects of this application include:

[0017] An unmanned surface vessel (USV) foam packaging box includes an upper box and a lower box that snap together to form a receiving cavity for accommodating the USV. On opposite sides of the lower box are recessed handle inserts and roller inserts embedded in the side walls of the lower box. The handle passes through the outer wall of the lower box and is connected to the handle insert. The roller insert has a mounting shaft extending to the outside of the lower box, on which a roller is detachably connected. By embedding the handle insert and roller insert into the side walls of the lower box, and connecting the handle to the handle insert, the stability and robustness of the connection between the handle and the lower box are improved. Similarly, the rollers are mounted on the mounting shaft of the roller insert. The roller insert is embedded, which increases the stability of the connection between the roller insert and the lower box. In this way, the rollers can be set up with the help of the mounting shaft of the roller insert. This avoids the risk of the rollers falling off due to the bumps between the rollers and the ground during long-distance movement, ensuring the integrity of the foam packaging box of the unmanned boat and facilitating the transportation of the unmanned boat.

[0034] like Figure 1 and Figure 2As shown, in one aspect of this application embodiment, an unmanned surface vessel foam packaging box 100 is provided, including an upper box body 110 and a lower box body 120 that are fastened together to form a receiving cavity. The receiving cavity is used to receive the unmanned surface vessel. On opposite sides of the lower box body 120, a handle insert 150 and a roller insert 160 are respectively provided and embedded in the side wall of the lower box body 120. The handle 140 passes through the outer wall surface of the lower box body 120 and is connected to the handle insert 150. The roller insert 160 has a mounting shaft 161 extending to the outside of the lower box body 120, and a roller 130 is detachably connected to the mounting shaft 161.

[0035] Specifically, the unmanned surface vessel (USV) foam packaging box 100 is made of EPP (Expandable Polypropylene) flame-retardant foam. EPP flame-retardant foam is a material made by adding flame retardants and other additives to polypropylene resin, and it has excellent properties such as flame retardancy, lightweight, cushioning, and environmental friendliness. By using EPP flame-retardant foam to make the USV foam packaging box 100, the weight of the USV foam packaging box 100 can be reduced. At the same time, the USV foam packaging box 100 can also protect the USV placed inside it from damage caused by collisions.

[0036] The unmanned surface vessel (USV) foam packaging box 100 includes an upper box body 110 and a lower box body 120. An opening is formed on the side of the upper box body 110 facing the lower box body 120, extending away from the lower box body 120 to form a receiving space. An opening is also formed on the side of the lower box body 120 facing the upper box body 110, extending away from the upper box body 110 to form a receiving space. The upper box body 110 and the lower box body 120 are fastened together, allowing the two receiving spaces to connect through the two openings, thus forming a receiving cavity for placing the USV. A handle insert 150 is embedded inside one side wall of the lower box body 120. It should be understood that "embedded" or "inlaid" here means that the side wall of the lower box body 120 completely covers the handle insert 150. A handle 140 can be inserted into the side wall containing the handle insert 150, thereby being fixedly connected to the handle insert 150. A roller insert 160 is embedded inside the other side wall of the lower housing 120. It should be understood that "embedded" or "set inside" here means that the side wall of the lower housing 120 completely covers the roller insert 160 (except for the mounting shaft 161 of the roller insert 160). The roller insert 160 has a mounting shaft 161 extending outside the lower housing 120, and a roller 130 is provided on the mounting shaft 161. The roller 130 is rotatably connected to the mounting shaft 161. At the same time, when the unmanned boat foam packaging box 100 is stored, the roller 130 can be removed from the mounting shaft 161.

[0037] In the manufacturing process of the unmanned surface vessel foam packaging box 100, by fixing the handle insert 150 and the roller insert 160 to opposite sides of the casting mold, EPP flame retardant is poured into the mold, and the EPP flame retardant is foamed to completely enclose the handle insert 150 and the roller insert 160 (except for the mounting shaft 161 of the roller insert 160), so that the handle insert 150 and the roller insert 160 can be embedded in the side wall of the box. The upper box 110 and the lower box 120 are fastened together to form a foam packaging box 100 for unmanned boats with a receiving cavity. During the transportation of the unmanned boat, the unmanned boat is placed in the receiving cavity. By gripping the handle 140, which is fixedly connected to the handle insert 150, the roller 130, which is rotatably connected to the mounting shaft 161, rolls on the ground, thereby realizing the transportation of the unmanned boat.

[0038] It should be understood, please refer to Figure 2 The handle insert 150 and the wheel insert 160 are located on opposite sides of the lower compartment 120, which means that the handle insert 150 and the wheel insert 160 are located at the head and tail (or front and rear) of the lower compartment 120, respectively, and their relative distribution is similar to that of an existing suitcase with a handle 140 and a wheel 130.

[0039] In some implementation methods, please refer to Figure 2 The number of roller inserts 160 can be two, so that two roller inserts 160 can be set at intervals on the left and right sides of the rear of the lower box 120 (distributed on opposite sides of the direction of movement of the packaging box). When the packaging box is moved by the handle 140, the rollers 130 installed on the two roller inserts 160 distributed on the left and right sides can fully contact the ground to form stable support and improve the convenience of movement.

[0040] In some embodiments, a limiting protrusion can be provided on the peripheral wall of the lower box 120 facing the upper box 110, and a limiting groove can be provided on the peripheral edge of the side of the upper box 110 facing the lower box 120. The lower box 120 and the upper box 110 can be fastened together by the cooperation of the limiting protrusion and the limiting groove. Alternatively, a connecting structure can be provided between the upper box 110 and the lower box 120, such as one or more of the following connection methods: hinge connection, snap-on connection, zipper, strap, etc. Of course, this application does not specifically limit the connection method between the upper box 110 and the lower box 120.

[0041] In some embodiments, the handle 140 may include a handle 140 body and a connector. One end of the connector is connected to the handle 140 body, and the other end is inserted into the side wall of the handle insert 150, thereby being fixedly connected to the handle insert 150. The handle 140 body and the connector can be movably or rotatably connected, facilitating a user's grip on the handle 140 body. The connector may be a connecting post or a rivet, or other parts that can securely connect the handle insert 150 and the handle 140; no specific limitation is made here.

[0042] Optionally, the handle insert 150 includes a first plate 151 and a second plate 152 respectively fixed to the opposite side of the first plate 151. The plate surface of the first plate 151 is parallel or approximately parallel to the wall surface of the side wall where the handle insert 150 is located, and the plate surface of the second plate 152 extends along the thickness direction of the side wall where the handle insert 150 is located.

[0043] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, a handle insert 150 is embedded inside one side wall of the lower housing 120. The handle insert 150 includes a first plate 151 and a second plate 152. The first plate 151 is placed parallel or approximately parallel to the side wall where the handle insert 150 is located. The second plate 152 is fixedly disposed on opposite sides of the first plate 151 and extends in the thickness direction of the side wall where the handle insert 150 is located. It should be noted that the extension length of the second plate 152 should not protrude outside the side wall. The handle 140 is fixedly connected to the first plate 151 by a connector, and the housing is moved by gripping the handle 140.

[0044] Optionally, the roller insert 160 also includes a fixing plate 162 and a fixing shaft 163 embedded in the side wall of the lower housing 120. The fixing shaft 163 is located on the side of the fixing plate 162 near the receiving cavity, and the fixing shaft 163 contacts the plate surface of the fixing plate 162. One end of the mounting shaft 161 is fixedly connected to the fixing shaft 163.

[0045] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, the roller insert 160 is embedded in the side wall of the lower housing 120, and the side wall where it is located is on opposite sides of the receiving cavity with the side wall where the handle insert 150 is located. The roller insert 160 also includes a fixing plate 162 and a fixing shaft 163. The fixing plate 162 is located on opposite sides of the side wall where the roller insert 160 is located and is not exposed outside the side wall. The fixing shaft 163 is located on the side of the fixing plate 162 facing the receiving cavity and is in contact with the plate surface of the fixing plate 162. One end of the fixing shaft 163 is fixedly connected to the mounting shaft 161 exposed outside the lower housing 120, and the roller 130 is rotatably connected to the mounting shaft 161. A limiting member 131 is provided at the end of the mounting shaft 161 away from the lower housing 120. The limiting member 131 is fixedly connected to the mounting shaft 161 to prevent the roller 130 from disengaging from the mounting shaft 161 during rotation. The limiting member 131 may include screws or nuts or other parts that can be fixedly connected to the mounting shaft 161, and is not limited here. During the rotation of the roller 130, the fixing plate 162 increases the contact area between the roller insert 160 and the lower housing 120, ensuring the stability and firmness of the roller 130 and the lower housing 120.

[0046] Optionally, the fixing plate 162 includes a third plate 164 and a fourth plate 165 whose plate surfaces intersect and are connected to each other. The third plate 164 and the fourth plate 165 are respectively located in adjacent side walls of the lower housing 120, and the fixing shaft 163 is located at the connection between the third plate 164 and the fourth plate 165.

[0047] Specifically, such as Figure 3 and Figure 5 As shown, the fixing plate 162 includes a third plate 164 and a fourth plate 165, which are arranged at a certain angle, such as vertically or approximately vertically. The area of ​​the third plate 164 is larger than that of the fourth plate 165 because the fourth plate 165 needs to avoid the clearance hole 121 mentioned below. The third plate 164 and the fourth plate 165 are respectively located in the adjacent side walls of the lower housing 120. One of the adjacent side walls is the bottom wall of the lower housing 120. The fixing shaft 163 is located at the connection between the third plate 164 and the fourth plate 165 facing the receiving cavity, and is used to bear the pressure transmitted to the fixing shaft 163 by the roller 130 due to bumps.

[0048] Optionally, there are two roller inserts 160, and a housing reinforcement insert 170 is also embedded in the side wall of the lower housing 120, with the housing reinforcement insert 170 located between the two roller inserts 160.

[0049] Specifically, such as Figure 2 , Figure 3 and Figure 4As shown, roller inserts 160 are used to connect the rollers 130 located at both ends of the lower housing 120. Therefore, there are two roller inserts 160. A housing reinforcement insert 170 is also embedded in the side wall where the roller inserts 160 are located, positioned between the two roller inserts 160. It should be noted that the extension length of the housing reinforcement insert 170 in the connection direction of the two rollers 130 should not be exposed in the clearance hole 121 mentioned below. When moving the housing, gripping the handle 140 will cause the unmanned surface vessel foam packaging box 100 to rise upwards, forming a certain angle with the ground. At this time, the unmanned surface vessel located within the receiving cavity abuts against the side wall where the housing reinforcement insert 170 is located due to gravity. The housing reinforcement insert 170 can improve the pressure and impact resistance of the side wall, preventing the unmanned surface vessel from squeezing and deforming the side wall.

[0050] Optionally, the handle insert 150, the roller insert 160 and the box reinforcement insert 170 are all evenly distributed with multiple through holes 180, and the lower box 120 has a filling portion 127 that fills into the through holes 180.

[0051] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, multiple through holes 180 are evenly distributed on the handle insert 150, the roller insert 160, and the box reinforcement insert 170. The filling part 127 of the lower box 120 fills the through holes 180. This increases the adhesion between the foam and the inserts, while reducing the weight of the inserts. It also prevents the situation where the un-holeed inserts block the side wall of the foam box, which would reduce the compressive and impact resistance of the side wall.

[0052] In some embodiments, the through hole 180 can be a round hole, a triangular hole, or a rectangular hole, and the specific shape of the through hole 180 is not limited.

[0053] In some embodiments, the handle insert 150, the roller insert 160, and the box reinforcement insert 170 are made of 304 stainless steel; they can also be iron sheets, which need to be electroplated or painted.

[0054] Optionally, a clearance hole 121 is provided on the bottom wall of the lower housing 120, which is used to avoid the thruster 190 of the unmanned vessel.

[0055] Specifically, such as Figure 2 and Figure 8As shown, the thruster 190 of the unmanned surface vessel (USV) protrudes from the surface of the USV hull. When the USV is placed inside the housing cavity and the foam packaging box 100 is moved, the box needs to be lifted. Due to gravity, the thruster 190 will be compressed between the USV hull and the foam packaging box 100. By providing a clearance hole 121, space can be provided for the installation of the thruster 190, preventing the weight of the USV from being concentrated on the thruster 190. It is important to note that the thruster 190 must not protrude outside the clearance hole 121 to avoid collisions with items outside the box.

[0056] Optionally, the accommodating cavity includes a first groove 122, a second groove 123, and a third groove 124 located in the lower housing 120. The second groove 123 and the third groove 124 are distributed on both sides of the first groove 122. The first groove 122 is used to accommodate the unmanned vessel, and the second groove 123 and the third groove 124 are used to accommodate the rollers 130, respectively.

[0057] Specifically, such as Figure 6 As shown, the receiving cavity includes a first groove 122 for mounting the unmanned surface vessel (USV) and a second groove 123 and a third groove 124 for mounting two rollers 130 respectively. During the storage of the USV, when it is placed in the first groove 122 of the USV foam packaging box 100, the stacking of the USV foam packaging boxes 100 will be interfered with by the rollers 130. The second groove 123 and the third groove 124 are provided in the receiving cavity to accommodate the rollers 130 respectively. At this time, the USV foam packaging boxes 100 can fit together, reducing the gap.

[0058] Optionally, the housing also includes a fourth slot 125 and a fifth slot 126 located in the lower housing 120, which are used to accommodate a remote control and a tool and accessory kit, respectively.

[0059] Specifically, such as Figure 6 As shown, when using the unmanned boat, it needs to be moved to a specific location using the unmanned boat foam packaging box 100. The unmanned boat needs to be debugged and prepared before being launched. By opening the fourth slot 125 and the fifth slot 126 in the housing cavity to accommodate the remote control and tool accessory package, the trouble of needing to prepare an extra box can be avoided.

[0060] Optionally, the accommodating cavity also includes a sixth trough 111 located in the upper housing 110, and a frame 112 for carrying the unmanned vessel is provided in the sixth trough 111.

[0061] Specifically, such as Figure 3 , Figure 7 and Figure 8As shown, a sixth groove 111 for mounting a boat frame 112 is provided inside the upper housing 110. The boat frame 112 is connected to the upper housing 110 via a fracture-type connection. This fracture-type connection allows control over the direction and shape of the fracture and eliminates the need for tool disassembly. By pressing, the connecting bridge 113 between the upper housing 110 and the boat frame 112 breaks, thereby detaching the boat frame 112 from the upper housing 110. Before launching the unmanned surface vessel (USV), it needs to be prepared for testing. Typically, the USV is placed on the ground, but the rough surface makes it difficult to secure the USV for testing. Now, the boat frame 112, which fits snugly against the USV, is used to secure it, facilitating the testing process.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
