Description

Technical Field

[0001] The utility model relates to the technical field of truck parts, and in particular to a modular photovoltaic top cover for a box of a heavy truck. Background Art

[0002] Heavy trucks have the advantages of large capacity and high efficiency. They have always occupied an important position in short-distance land transportation and are mainly used for the transportation of goods such as slag and ore.

[0003] For a long time, the cargo box of heavy trucks has been open at the top. During transportation, the cargo in the cargo box is not only vulnerable to bad weather such as rain, snow and strong wind, but also the cargo that falls out may affect the surrounding environment. Therefore, the cargo box of heavy trucks is usually covered with tarpaulin. Although it can avoid the above situation to a certain extent, the tarpaulin usually cannot completely cover the cargo and is easy to be blown off during transportation.

[0004] Therefore, it is hoped to design a hard top cover for a box that can be opened and closed quickly by electric folding, which can more reliably protect the goods in the box, and the structure of the top cover itself is more reliable. Utility Model Content

[0005] In order to solve the technical problem that the existing heavy truck box is covered with tarpaulin but has poor shielding effect, the utility model provides a modular photovoltaic top cover for the box of a heavy truck.

[0006] The technical solution is as follows:

[0007] The first aspect of the present application relates to a modular photovoltaic roof cover for a box of a heavy truck, comprising a plurality of thin plate profiles of equal length, each of which is arranged side by side in a width direction, and adjacent thin plate profiles are connected by loose-leaf connections, so that each thin plate profile can be unfolded to form a thin plate structure or folded into a stack, and reinforcing block grooves are provided on both sides of the outer edges in the width direction of the thin plate profile at positions where the loose-leaf connections are installed, and solid reinforcing blocks are fixedly connected in the reinforcing block grooves, and each loose-leaf is respectively locked on the corresponding reinforcing block by screws, and the upper surfaces of at least some of the continuously arranged thin plate profiles are installed with the same number of photovoltaic panels, and each photovoltaic panel constitutes at least one group of photovoltaic panel arrays arranged side by side in the width direction of the thin plate profile;

[0008] In any thin plate profile installed with photovoltaic panels: the two reinforcing blocks are both installed with the same number of wiring terminals as the photovoltaic panel array, the inner ends of the wiring terminals on the two reinforcing blocks are electrically connected in pairs through the main power line buried inside the thin plate profile, and each photovoltaic panel is electrically connected to the corresponding main power line through the branch power line buried inside the thin plate profile;

[0009] Between the adjacent thin plate profiles on which the photovoltaic panels are installed: the outer ends of the connection terminals on the adjacent reinforcement blocks are electrically connected in pairs through flexible wiring.

[0010] The modular photovoltaic roof cover of the box of a heavy truck adopts the above-mentioned method. The main body is composed of multiple thin plate profiles and connected by loose-leaf hinges. It is not only light in weight and meets the lightweight design requirements, but also the interior of the profiles are hollow structures, which are easy to wire and route. Photovoltaic panels are installed on at least part of the thin plate profiles, and together with energy storage batteries, they can power the electric mechanism that drives the top cover to fold and open. What is important is that the number of thin plate profiles and photovoltaic panels can be increased or decreased according to actual needs to achieve modular design. At the same time, the hard top cover has high structural strength and will not be blown over by the wind, thereby improving the reliability of the top cover installation.

[0011] In some embodiments, in any thin plate profile installed with a photovoltaic panel, the outer ends of the wiring terminals on one reinforcement block are PIN needle plug connectors, and the outer ends of the wiring terminals on the other reinforcement block are PIN pin jack plug connectors, and the two ends of the cable are respectively a PIN needle plug connector and a PIN pin jack plug connector.

[0014] In some embodiments, the photovoltaic panels are riveted onto corresponding thin plate profiles via pressure strips around their circumferential outer edges.

[0015] In some embodiments, the inner surfaces of the photovoltaic panels are bonded to corresponding thin plate profiles.

[0016] In some embodiments, the interior of the thin plate profile has a plurality of profile channels running through it along its length direction, wherein both ends of some of the profile channels are embedded with supporting plugs made of metal or plastic materials, and both ends of the remaining profile channels are embedded with dust-proof plugs made of foam materials, and both ends of the thin plate profile are provided with mounting through holes corresponding to each supporting plug, and each mounting through hole runs through the corresponding supporting plug.

[0022] The utility model is further described below in conjunction with embodiments and drawings.

[0023] like Figure 1-Figure 5 As shown, a modular photovoltaic roof for a heavy truck box mainly includes a plurality of thin plate profiles 1 of equal length, that is, the thin plate profiles 1 are made of aluminum or alloy and formed by an extrusion process, and the lengths of the thin plate profiles 1 are equal. Therefore, the thin plate profiles 1 are not only light in weight and high in strength, meeting the requirements of lightweight design, but also the inside of the thin plate profiles 1 are hollow structures, which are easy to wire and route.

[0024] Each thin plate profile 1 is arranged side by side along the width direction, and adjacent thin plate profiles 1 are connected by hinges 2, so that adjacent thin plate profiles 1 are hinged, so that each thin plate profile 1 can be unfolded to form a thin plate structure or folded into a stack. In this embodiment, when each thin plate profile 1 is unfolded, each thin plate profile 1 presents a wavy thin plate structure, so that the photovoltaic panel 3 can obtain a longer lighting time and light intensity.

[0025] Furthermore, on both sides of the outer edge of the thin plate profile 1 in the width direction, at the position where the hinge 2 is installed, a reinforcing block groove 1a is provided, and a solid reinforcing block 11 is fixedly connected in the reinforcing block groove 1a to improve the structural strength of the hinge installation position and avoid deformation. In addition, the outer edge of the reinforcing block 11 is flush with the outer edge of the thin plate profile 1 to avoid interference when the whole is folded. Therefore, each hinge 2 is locked to the corresponding reinforcing block 11 by screws, which is simple and reliable.

[0026] In this embodiment, at least part of the upper surfaces of the continuously arranged thin plate profiles 1 are all installed with the same number of photovoltaic panels 3, and each photovoltaic panel 3 constitutes at least one group of photovoltaic panel arrays A arranged side by side along the width direction of the thin plate profile 1. It is usually preferred to set one or two groups of photovoltaic panel arrays A, see Figure 1 In this embodiment, two groups of photovoltaic panel arrays A are provided.

[0027] Therefore, by installing the photovoltaic panel 3 and cooperating with the energy storage battery, power can be supplied to the electric mechanism that drives the top cover to fold and open, and the excess electric energy can also be used for other purposes such as lighting.

[0028] It should be pointed out that the number of thin plate profiles 1 on which the photovoltaic panels 3 are to be installed depends on actual needs, and it is usually not necessary to install the photovoltaic panels 3 on all the thin plate profiles 1 to avoid waste.

[0029] In this embodiment, in any thin plate profile 1 installed with photovoltaic panels 3: the two reinforcing blocks 11 are both installed with the same number of wiring terminals as the photovoltaic panel array A, and the inner ends of the wiring terminals on the two reinforcing blocks 11 are electrically connected in pairs through the main power line 4 buried in the thin plate profile 1, and each photovoltaic panel 3 is electrically connected to the corresponding main power line 4 through the branch power line 5 buried in the thin plate profile 1. The hidden wiring design not only improves the service life of the wires, but also prevents the wires from being cut by foreign objects in the wind, thereby improving safety. In addition, in this embodiment, between adjacent thin plate profiles 1 installed with photovoltaic panels 3: the outer ends of the wiring terminals on adjacent reinforcing blocks 11 are electrically connected in pairs through flexible wiring 6. The electrical connection method using the wiring and stage terminals is not only highly reliable, but also the flexible wiring 6 can be bent at will and is durable.

[0030] Furthermore, in any thin plate profile 1 installed with the photovoltaic panel 3, the outer ends of the wiring terminals on one reinforcement block 11 are all PIN pin plug connectors, and the outer ends of the wiring terminals on the other reinforcement block 11 are all PIN pin jack plug connectors, and the two ends of the cable 6 are respectively PIN pin pin plug connectors and PIN pin jack plug connectors, that is, the PIN pin plug connector of the cable 6 is plug-in-matched with the PIN pin jack plug connector of the wiring terminal on the reinforcement block 11, and the PIN pin jack plug connector of the cable 6 is plug-in-matched with the PIN pin pin plug connector of the wiring terminal on the reinforcement block 11. The PIN pin plug-in electrical connection method has high reliability and good stability, and is not prone to loosening and falling off.

[0031] See also Figure 1-Figure 4 A wiring notch 1b is provided on one side surface of the thin plate profile 1 in the thickness direction, and the wiring notch 1b is located between the two reinforcing blocks 11, so that the connection positions of each power main line 4 and each branch power line 5 are exposed in the wiring notch 1b, so as to facilitate the wiring operation after the photovoltaic panel 3 is installed on the thin plate profile 1.

[0032] At the same time, after the wiring is completed, the wiring gap 1b is sealed with a sealing cover plate 7 to protect the internal circuit from external corrosion and avoid the problem of circuit short circuit.

[0033] See also Figure 4 and Figure 5The thin plate profile 1 is provided with junction box notches 1c located on the inner side of the corresponding photovoltaic panel 3. The junction boxes 3a installed on the inner side of each photovoltaic panel 3 are respectively embedded in the corresponding junction box notches 1c and electrically connected to the corresponding branch power lines 5, that is, one end of the branch power line 5 is electrically connected to the connector of the junction box 3a, and the other end is electrically connected to the main power line 4. The junction box 3a of the above design is sealed inside the photovoltaic panel 3, ensuring the sealing performance between the photovoltaic panel 3 and the thin plate profile 1.

[0034] For further information, see Figure 2 , Figure 3 and Figure 5 The photovoltaic panels 3 are all riveted on the corresponding thin plate profiles 1 by the pressure strips 8 around the circumferential outer edges thereof. The riveting installation method ensures the reliability of the installation of the photovoltaic panels 3 and is durable.

[0035] Furthermore, the inner surfaces of the photovoltaic panels 3 are all bonded to the corresponding thin plate profiles 1, that is, the photovoltaic panels 3 are first bonded to the thin plate profiles 1, and then the outer edges of the photovoltaic panels 3 are riveted to the thin plate profiles 1 through the pressure strips 8, which further improves the reliability of the installation of the photovoltaic panels 3. At the same time, the bonding between the photovoltaic panels 3 and the thin plate profiles 1 can be made of sealant, thereby further improving the sealing performance between the photovoltaic panels 3 and the thin plate profiles 1.

[0036] See also Figure 4 The inside of the thin plate profile 1 has a number of profile channels 1e that penetrate along its length direction, wherein both ends of some of the profile channels 1e are embedded with supporting plugs 9 made of metal or plastic materials, and both ends of the other parts of the profile channels 1e are embedded with dust plugs 10 made of foam materials. Both ends of the thin plate profile 1 are provided with mounting through holes 1d that correspond to each supporting plug 9 one by one, and each mounting through hole 1d penetrates the corresponding supporting plug 9, so as to facilitate the connection of electric drive components at both ends of the length direction of the thin plate profile 1 to drive each thin plate profile 1 to open or fold. Due to the high structural strength of the supporting plug 9, the connection will not be deformed, thereby ensuring the reliability of the connection. The two ends of the remaining profile channels 1e are sealed with ordinary dust plugs 10 made of hard foam material, which not only ensures the sealing performance but also meets the lightweight design requirements.

[0037] See also Figure 4 In this embodiment, both sets of power line main lines 4 pass through the outer reinforcing block 11 of the thin plate profile 1 at the outermost end to facilitate electrical connection with the energy storage battery.

[0038] Furthermore, the inner reinforcing block 11 of the innermost thin plate profile 1 provided with the photovoltaic panel 3 is provided with protective plugs corresponding to the two groups of power main lines 4 respectively, which can be disassembled so as to serve as a main line on-off test point.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
