Description

Technical Field

[0001] The present invention belongs to the technical field of thermal insulation boxes, and in particular relates to a thermal insulation box that is convenient for drone delivery. Background Art

[0002] High-altitude swarming drones are becoming a mainstream battlefield reconnaissance method. However, drones have certain operating temperature requirements for their batteries. Low temperatures prevent them from fully utilizing their performance and may even cause them to malfunction. Therefore, an insulated box structure is required to ensure that the starting temperature meets the battery's operating environment.

[0003] As a key component of composite molding boxes, thermal boxes have a wide range of applications. They isolate the products being stored and transported from the external temperature environment, providing a suitable temperature environment for storage and transportation. Therefore, thermal boxes can be used as transport carriers for drones, opened at a suitable location, and deployed. The thermal insulation of the thermal box prevents the drone from starting at low temperatures, allowing it to operate quickly after being released from the box.

[0004] Existing thermal insulation boxes are made of a skeleton skin and foam layer structure, which is heavy and poses great risks during transportation and lifting. As a result, existing thermal insulation boxes cannot meet the requirements of fixed-point delivery of drones. Summary of the Invention

[0005] In response to one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides an insulated box that is convenient for drone delivery, so as to solve the problem that the existing insulated boxes cannot achieve fixed-point delivery by drones.

[0010] As a further improvement of the present invention, the upper and lower end surfaces of the box body are covered with a metal frame, an opening for the closing protrusion to be embedded in the middle of the metal frame is reserved, and a sealing strip is embedded in the circumference of the opening.

[0011] As a further improvement of the present invention, a first metal cover plate is provided on the side of the upper cover facing the box body, and the closing protrusion is provided on the first metal cover plate.

[0012] As a further improvement of the present invention, the lower cover is provided with a second metal cover plate on the side facing the box body, and the closing protrusion is provided on the second metal cover plate;

[0013] A placement notch is provided on the closed protrusion, a metal installation pre-embedded is connected in the placement notch, and a limiting block is fixed on the metal installation pre-embedded.

[0014] As a further improvement of the present invention, the limit block is connected to the metal mounting embedded thread;

[0015] A disc protrusion is formed on one end of the limiting block away from the metal installation embedded end. A circular placement opening is opened at the center of the disc protrusion, and a plurality of engaging notches are opened in the circumference of the disc protrusion toward the placement opening.

[0016] As a further improvement of the present invention, a hook is fixed on one side wall of the outer periphery of the box.

[0017] As a further improvement of the present invention, the hook includes a fixing frame attached to the side wall of the box body, and the fixing frame extends out a “┐”-shaped hanging bracket along a side away from the box body.

[0018] As a further improvement of the present invention, a side hole is opened on one of the side walls of the outer periphery of the box body, and the side hole connects the inside and outside of the box body, and a side cover is detachably connected to the side hole.

[0019] As a further improvement of the present invention, the hasp lock is further provided with a rope threading hole.

[0020] As a further improvement of the present invention, a plurality of tail wing limits are provided on the circumferential inner wall of the box body, and the plurality of tail wing limits are arranged at the junction of the circumferential side walls of the box body. The plurality of tail wing limits limit the internal space of the box body to a "cross" space.

[0021] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0022] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

[0023] (1) The thermal insulation box of the present invention is convenient for drone delivery. The thermal insulation box is made of a composite of polyurethane foam and glass fiber as a whole, so that the thermal insulation box as a whole has a certain mechanical strength and is light in weight, which is convenient for transportation of the thermal insulation box. At the same time, the upper cover and the lower cover of the box are set to be openable and closable with a snap lock connection, so that the upper and lower covers of the box can be opened and closed according to needs, which is convenient for the placement and delivery of the drone. In addition, the present application provides closing protrusions on the upper cover and the lower cover, and uses the closing protrusions to seal the upper and lower ends of the box to improve the thermal insulation effect inside the box, so that when the thermal insulation box is transported to a low-temperature environment, the internal temperature of the box can still ensure the normal start-up of the drone, ensuring the fixed-point delivery and start-up of the drone.

[0024] (2) The thermal insulation box of the present invention is convenient for drone delivery. A metal frame is provided on the upper and lower end surfaces of the box body, and a sealing strip is embedded in the circumference of the opening of the metal frame.

[0039] Example:

[0040] See also Figures 1 to 5 The thermal insulation box for drone delivery in the preferred embodiment of the present invention includes a box body 1, and an upper cover 2 and a lower cover 3 are respectively provided at the upper and lower ends of the box body 1, wherein the box body 1, the upper cover 2 and the lower cover 3 are all made of a composite of polyurethane foam and glass fiber; at the same time, one end of the upper cover 2 and the lower cover 3 is connected to the box body 1 through a rotating part, and the other end of the upper cover 2 and the lower cover 3 is connected to the box body 1 through a buckle in an openable and closable manner; the upper cover 2 and the lower cover 3 are provided with a closing protrusion 4 on the side facing the box body 1, and the closing protrusion 4 is fitted with the opening of the box body 1 to seal the upper and lower end surfaces of the box body 1.

[0041] The insulated box of the present invention, which is convenient for drone delivery, is made of a composite of polyurethane foam and glass fiber as a whole, so that the insulated box as a whole has a certain mechanical strength and the advantage of being light in weight, which facilitates the transportation of drones by the insulated box and also facilitates the transportation of the insulated box by transportation vehicles; at the same time, the upper cover 2 and the lower cover 3 of the box body 1 are set to an openable and closable form connected by a buckle lock 5, so that the upper and lower covers 3 of the box body 1 can be opened and closed as needed, which is convenient for the placement and delivery of drones. In addition, the present application provides a closed protrusion 4 on the upper cover 2 and the lower cover 3, and uses the closed protrusion 4 to seal the upper and lower ends of the box body 1 to improve the heat preservation effect inside the box body 1, so that when the insulated box is transported to a low-temperature environment, the internal temperature of the box body 1 can still ensure the normal start-up of the drone, ensuring the fixed-point delivery and start-up of the drone.

[0042] It is worth noting that the thermal insulation box in this application that is convenient for drone delivery is made of a composite of polyurethane foam and glass fiber. The composite material of polyurethane foam and glass fiber has the characteristics of being light in weight and having a certain strength. This application mainly utilizes the inherent characteristics of these two materials and does not improve the ratio or performance of the two. It belongs to the use of conventional polyurethane foam and glass fiber composite materials.

[0043] Furthermore, as a preferred embodiment of the present invention, a metal frame 7 is provided at the upper and lower end surfaces of the box body 1 in the present application. An opening is left in the middle of the metal frame 7 for the sealing protrusion 4 to be embedded, and a sealing strip is embedded around the opening. The present application overcomes the problem that the polyurethane foam and glass fiber composite material is prone to deformation during long-term use by providing the metal frame 7 at the upper and lower end surfaces of the box body 1 and using the metal frame 7 to maintain the shape of the end surface of the box body 1. The sealing strip has a certain deformation ability, so that when the sealing protrusion 4 is embedded in the box body 1, the sealing strip can fit tightly around the sealing protrusion 4, thereby ensuring the sealing performance between the box body 1 and the upper cover 2 and lower cover 3.

[0044] Furthermore, as a preferred embodiment of the present invention, the upper cover 2 in this application is provided with a first metal cover plate 8 on the side facing the box body 1, and the closing protrusion 4 is provided on the first metal cover plate 8. As mentioned above, the box body 1, the upper cover 2 and the lower cover 3 in this application are all made of a composite of polyurethane foam and glass fiber, and their overall hardness is relatively low, making it difficult to maintain their shape. In this application, the first metal cover plate 8 is provided on the side of the upper cover 2 facing the box body 1, and the shape of the upper cover 2 is constrained by the first metal cover plate 8, so that when the upper cover 2 is provided on the box body 1, the first metal cover plate 8 is in contact with the metal frame 7, and neither the upper cover 2 nor the box body 1 will be deformed, and the upper cover 2 and the box body 1 can be tightly combined. Correspondingly, when the closing protrusion 4 is pressed into the box body 1, the closing protrusion 4 is supported by the first metal cover plate 8, and it will not be deformed together with the main part of the upper cover 2, ensuring that the closing protrusion 4 closes the upper end of the box body 1.

[0045] Furthermore, as a preferred embodiment of the present invention, the lower cover 3 in this application is provided with a second metal cover plate 9 on the side facing the box body 1, and the second metal cover plate 9 is also provided with a closed protrusion 4; at the same time, a placement slot is provided on the closed protrusion 4, and a metal mounting pre-embedded portion 10 is connected to the placement slot, and a limiting block 11 is fixed on the metal mounting pre-embedded portion 10. The insulated box for facilitating drone delivery in this application is mainly used for fixed-point delivery of drones. The overall shape of the drone in this application is similar to that of a rocket, and its head is elliptical. In order to achieve the limiting fixation of the drone, this application provides a limiting block 11 on the lower cover 3, and the limiting block 11 cooperates with the head of the drone to achieve the limiting fixation of the end of the drone. Since the lower cover 3 is made of soft material, the end of the drone is directly pressed on the lower cover 3, which can easily cause the lower cover 3 to deform. The limit block 11 cannot be directly fixed on the closed protrusion 4. Therefore, the present application corresponds to opening a placement slot on the closed protrusion 4, setting a metal mounting pre-embedded 10 inside, and then fixing the limit block 11 on the metal mounting pre-embedded 10 to ensure the stable setting of the limit block 11 on the lower cover 3.

[0046] Correspondingly, the limit block 11 in the present application is connected to the metal mounting pre-embedded 10 via a thread, and a disc-shaped protrusion is formed on the end of the limit block 11 facing away from the metal mounting pre-embedded 10. The center of the disc-shaped protrusion is provided with a circular placement opening, and a plurality of engaging notches are provided around the disc-shaped protrusion toward the placement opening. The placement opening in the center of the disc-shaped protrusion is used to cooperate with the head of the drone to limit and fix it. The engaging notches around the disc-shaped protrusion are used to cooperate with tightening the limit block 11 on the metal mounting pre-embedded 10 to ensure that the limit block 11 is fixed to the lower cover 3.

[0047] Furthermore, in the present application, a hook 12 is fixed on one of the side walls of the outer periphery of the box body 1. The hook 12 specifically includes a fixing frame attached to the side wall of the box body 1, and the fixing frame extends a "┐"-shaped hanging bracket along the side away from the box body 1. The main body of the box body 1 in the present application is a soft structure. In order to prevent the hook 12 from sinking into the box body 1, resulting in an unstable connection between the hook 12 and the external transport carrier, the hook 12 in the present application correspondingly includes a fixing frame. The fixing frame increases the contact area with the box body 1 to ensure the stability of the connection between the box body 1 and the fixing frame. The "┐"-shaped hanging bracket is then connected to the fixing frame to achieve a stable setting of the hook 12 on the box body 1. It is worth noting that the transport carrier in the present application is a hot air balloon. The hook 12 can directly hang the insulated box that is convenient for drone delivery on the hot air balloon to achieve the transportation of the insulated box.

[0048] Furthermore, as a preferred embodiment of the present invention, a side hole 13 is provided on one of the side walls of the outer periphery of the box 1 in this application. This side hole 13 connects the inside and outside of the box 1, and a side cover 14 is detachably connected to the side hole 13. Because the box 1 in this application is a long rectangular cylindrical structure, after the drone is placed in the box 1, it is impossible to confirm whether the drone's head is placed at the stop block 11 or whether the drone's placement is offset. Improper placement of the drone may cause problems such as inadequate or malfunctioning drone delivery. Therefore, the present application provides a side hole 13 on the side wall of the box 1. Through the side hole 13, the interior of the box 1 can be observed to determine whether the drone is properly placed. However, the side hole 13 will impair the thermal insulation performance of the thermal insulation box. The present application provides a side cover 14. When it is necessary to check the placement of the drone, the side cover 14 can be removed. When the drone needs to be transported, the side cover 14 is replaced over the side hole 13 to ensure the thermal insulation performance of the thermal insulation box.

[0049] Furthermore, as a preferred embodiment of the present invention, a plurality of tail limiters 6 are further provided on the circumferential inner wall of the box body 1 of the present application. The box body 1 in the present application is a rectangular parallelepiped structure, and a plurality of tail limiters 6 are provided at the junction of the circumferential side walls of the box body 1 to limit the internal space of the box body 1 to a "cross" space, so as to achieve the limitation of the tail of the UAV. The tail limiter 6 is mainly used to fix the tail of the UAV, and the limiting block 11 at the head of the UAV is used to limit the overall fixation of the UAV and achieve stable transportation of the UAV. The "cross" space formed by the tail limiter 6 can limit the swing of the UAV, avoiding problems such as shaking during transportation causing the rotation of the UAV in the box body 1, and then causing secondary swing of the box body 1.

[0050] Furthermore, the buckle lock 5 of the present application is provided with a rope threading hole, which is used to thread ropes through the upper and lower ends of the box body 1 to secure it to the hot air balloon, thereby achieving stable fixation of the insulated box. At the same time, a retractable rope is directly connected to the buckle lock 5, which can be used to drive the buckle lock 5 to open, thereby releasing the drone at a fixed location.

[0051] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
