[0042] The embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1 to 6 The embodiments of the present application provide a cab and a vehicle.

[0043] As shown in Figure 1 and Figure 2 An aspect of the embodiments of the present application provides a cab. The cab comprises: a cab frame 100, the cab frame 100 comprising a floor frame 110, the height of the floor frame 110 at the driving side being lower than the height of the floor frame 110 at the non-driving side, and the interior of the floor frame 110 at the non-driving side enclosing a storage space 111.

[0044] The cab provided by the embodiments of the present application makes the floor frame 110 at the non-driving side enclose the storage space 111, compared with the traditional flat floor frame 110, the storage capacity of the cab is improved, which is conducive to placing the parts of the vehicle, such as the fuel cell 300, in the storage space 111 according to the needs, and provides convenience for the cab to adapt to the layout of the new vehicle. Moreover, the storage space 111 is located at the non-driving side of the interior of the cab, which does not affect the driving space of the driver and does not interfere with the normal driving of the driver.

[0045] Further, the cab further comprises a cab panel, as shown in Figure 3 and Figure 5 The cab panel comprises a floor panel 210, which is laid on the upper surface of the floor frame 110. On the one hand, the floor panel 210 can separate the interior space of the cab and the storage space 111, so that they do not affect each other, and on the other hand, it is convenient to carry the driver, the seat, etc.

[0046] Specifically, the floor panel 210 can completely cover the upper surface of the floor frame 110. Since the height of the floor frame 110 at the non-driving side is higher, the height of the part of the floor panel 210 covering it is also higher. Further, the part of the floor panel 210 at the non-driving side can be configured as a bunk for the driver to rest. At this time, referring to Figure 5As shown, the storage space 111 can be extended as far as possible to the front end of the cab frame 100, and the floor panel 210 can be extended horizontally to the front end of the cab frame 100, so that the berth has sufficient length for the driver to rest. Of course, the cab can also include a bed panel (not shown in the figure) laid on the portion of the floor panel 210 on the non-driving side. In this case, the storage space 111 can be spaced from the front end of the cab frame 100, and the portion below the bed panel can be suspended. The size of the storage space 111 can be designed as needed, and the need for the bed panel can be designed accordingly. In this way, although the non-driving side of the cab interior cannot be provided with a co-driver seat, a berth can be provided for the driver to rest. Especially for long-distance transport vehicles, the frequency of use of the co-driver seat is very low, and it is more practical to change this position to a berth.

[0047] Of course, the portion of the floor panel 210 on the non-driving side can also be used as a bench. Regardless of the use, the portion of the floor panel 210 that is raised can serve other purposes in addition to avoiding the storage space 111, and can provide convenience for the driver while simplifying the structure.

[0048] In addition, as shown in Figure 1 , Figure 2 and Figure 4 , a seat mounting structure 113 for connecting a seat can be provided on the portion of the floor frame 110 on the driving side. This facilitates the driver to drive the vehicle on the seat on the driving side. Moreover, since the portion of the floor frame 110 on the driving side is lower than the portion on the non-driving side, the seat mounting structure 113 is relatively sunken, as shown in Figures 4 to 6 , which facilitates the accommodation of the seat and ensures that the vehicle is not increased in height due to the storage space 111.

[0049] For the convenience of replacing or repairing the components in the storage space 111, it is of course also possible to simply take and place the components. Further, in some embodiments, as shown in Figures 1 to 6 , a first opening 211 is provided in the floor panel 210 and communicates with the storage space 111, and a first maintenance cover 212 is provided at the first opening 211.

[0050] In these embodiments, when it is necessary to take and place the components in the storage space 111, the components in the storage space 111 can be taken out from the first opening 211 by opening the first maintenance cover 212 on the floor panel 210, and then taken out from the interior space of the cab, which is convenient to operate.

[0051] As an example, the first maintenance cover 212 is hingedly connected to the floor panel 210, and the first maintenance cover 212 is flipped open.

[0052] As an example, as shown in Figure 6As shown, the first maintenance cover 212 is connected to the edge of the first opening 211 by a first bolt 213. Thus, when the first maintenance cover 212 is opened, the first bolt 213 needs to be disassembled, and then the first maintenance cover 212 is opened. Although the operation is slightly cumbersome compared with flipping the first maintenance cover 212, the first maintenance cover 212 can be directly moved upward and then translated to open the first opening 211, without the need to provide a large operation space for the opening of the first maintenance cover 212 in the cab.

[0053] In some embodiments, as shown in Figure 5 and Figure 6 , the cab frame 100 further comprises a top frame 140 located above the floor frame 110, at least a portion of the top frame 140 enclosing a second opening 141 located above the first opening 211; and the cab panel further comprises a top panel 240 detachably or reversibly arranged on the top frame 140 and covering the second opening 141.

[0054] Thus, when the components in the storage space 111 are maintained or replaced, the top panel 240 can be disassembled or reversed to open the second opening 141, and the first maintenance cover 212 is opened to open the first opening 211, so that the components in the storage space 111 can be directly lifted out of the cab through the first opening 211 and the second opening 141, which is convenient to operate. Moreover, the top panel 240 completely covers the top frame 140, and the top panel 240 itself has no gap, which has no risk of water leakage and has a good appearance effect.

[0055] As an example, as shown in Figure 6 , the top panel 240 is fixed to the top frame 140 by a second bolt 241. The top panel 240 is firmly installed and is convenient to disassemble.

[0056] Further, in some embodiments, as shown in Figure 1 , Figure 2 and Figure 5 , one side of the floor frame 110 in the width direction encloses a third opening 112 for communicating the storage space 111 with the outside. The cab further comprises a second maintenance cover (not shown in the figure) arranged at the third opening 112.

[0057] In these embodiments, when the components in the storage space 111 are maintained or replaced, the second maintenance cover only needs to be opened, and then the components in the storage space 111 can be pulled out, which is convenient to operate. Moreover, the second maintenance cover is located at one side of the floor frame 110 in the width direction and close to the non-driving side, and the outside of the second maintenance cover has sufficient space to open the second maintenance cover, which is convenient to open the cover.

[0058] In this case, the cab can not have the first maintenance cover 212 described above, of course, it can also have the first maintenance cover 212 described above at the same time, so that the components in the storage space 111 can be removed in multiple positions.

[0059] In some embodiments, as shown in Figure 1 and Figure 2 The cab frame 100 further comprises a first side frame 120 connected to one side of the floor frame 110 in the width direction and arranged close to the driving side, the first side frame 120 extends to the bottom of the floor frame 110, and the first side frame 120 is used to connect the door body; a second side frame 130 connected to the other side of the floor frame 110 in the width direction and arranged close to the non-driving side, the second side frame 130 is connected to the upper edge of the floor frame 110 to be higher than the storage space 111, and the second side frame 130 is used to connect the window body, and the second maintenance cover is fixed to the floor frame 110 and lower than the second side frame 130.

[0060] In these embodiments, the cab frame 100 further comprises a first side frame 120 and a second side frame 130, the first side frame 120 can be connected to the door body as the driving side door body, which is convenient for the driver to open the door body to enter the cab. The lower edge of the second side frame 130 is connected to the upper edge of the floor frame 110, and the window body is installed thereon, which is convenient for the light from the outside to enter the cab interior through the window body, and also convenient for the driver to observe the external environment through the window body, which provides good conditions for the driver to drive safely. Moreover, the second maintenance cover is fixed to the floor frame 110 and lower than the second side frame 130, when replacing the internal components of the storage space 111, only the second maintenance cover of the lower half of the cab needs to be opened, without the need for a larger operating space.

[0061] As an example, the upper end of the second maintenance cover is rotationally connected to the upper edge of the floor frame 110. Among them, the second maintenance cover can be connected to the floor frame 110 through a damper, so that the second maintenance cover can remain in the open state under the damping action. In this way, when taking and placing the internal components of the storage space 111, it is not necessary to hold the second maintenance cover by hand, which is convenient to operate, and can avoid the second maintenance cover from closing suddenly and injuring the user. The one end of the supporting rod can also be rotationally connected to the second maintenance cover, and the supporting rod is used to prop up the second maintenance cover, so that the second maintenance cover remains in the open state. The supporting rod has simple structure, convenient processing and low cost, and the use of the mechanical form of the supporting rod to prop up the second maintenance cover has high reliability.

[0062] In addition, the second maintenance cover can also be equipped with a locking assembly (not shown in the figure), which is used to lock the second maintenance cover at the third opening 112. It can effectively avoid the second maintenance cover from being opened by mistake, and avoid the impurities such as dust or sewage from the outside from entering the storage space 111. Here, the locking assembly can be similar to the door lock in the related art, which will not be described in detail here.

[0063] As an example, the second maintenance cover is connected with the floor frame 110 by bolts. The second maintenance cover is firmly installed. When the third opening 112 needs to be opened, the second maintenance cover can be removed by disassembling the bolts, which is convenient to operate.

[0064] In other embodiments, the second maintenance cover extends from the top of the cab frame 100 to the bottom of the cab frame 100, and the part of the second maintenance cover that is higher than the storage space 111 is provided with a window.

[0065] In these embodiments, the second maintenance cover can serve as a co-driver door body, even consistent with the traditional co-driver door body, extending from the top of the cab frame 100 to the bottom of the cab frame 100, which is beneficial to the symmetrical design of the door bodies on the left and right sides of the cab, and has a good appearance effect. When the second maintenance cover is opened, in addition to the third opening 112 of the storage space 111 being connected with the outside, the space above the storage space 111 inside the cab frame 100 can also be connected with the outside. In addition, the window on the second maintenance cover is higher than the storage space 111, which facilitates the light from the outside to pass through the window into the cab interior, and also facilitates the driver to observe the external environment through the window, providing good conditions for the safe driving of the driver.

[0066] In this case, one end of the second maintenance cover in the width direction can be hingedly connected with the cab frame 100.

[0067] Of course, the connection mode of the second maintenance cover is not limited to the above example, as long as the second maintenance cover can be opened to connect the storage space 111 with the outside.

[0068] Further, in some embodiments, as shown in Figure 5 The storage space 111 is used to store the fuel cell 300. Since the non-driving side of the cab interior has a larger space, the storage space 111 can also be larger, thus facilitating the accommodation of the fuel cell 300, and the interior space of the cab is reasonably arranged.

[0069] Moreover, in the case where the cab has the above-mentioned first maintenance cover 212 and / or the second maintenance cover, the fuel cell 300 in the storage space 111 can be directly taken out by opening the first maintenance cover 212, without the need to overturn the entire cab as in the traditional engine disassembly, greatly facilitating the maintenance or replacement of the fuel cell 300.

[0070] Specifically, in a conventional hydrogen energy heavy truck, the fuel cell 300 is arranged below the middle of the cab and fixed on the chassis longitudinal beam, i.e. the position of the engine of the original fuel vehicle. This results in that when the fuel cell 300 needs to be replaced or repaired, the cab needs to be first turned over by about 40° by a turnover mechanism, so that the fuel cell 300 is exposed, the lines and pipelines of the fuel cell 300 are disconnected, the fixing bolts of the fuel cell 300 are loosened, and then the fuel cell 300 can be lifted and taken out. The operation is very troublesome. In the embodiment, the fuel cell 300 in the storage space 111 can be directly taken out by opening the first maintenance cover 212 or the second maintenance cover, and the operation is convenient.

[0071] Of course, the storage space 111 can also store other components, not limited to the fuel cell 300.

[0072] In specific applications, the storage space 111 is also used to store a fuel cell mounting structure. The fuel cell mounting structure includes a bracket fixed on the floor frame 110 by bolts, and a plurality of suspensions distributed on the bracket for supporting the fuel cell 300. When the fuel cell 300 needs to be repaired or replaced, the bolts on the bracket are first disassembled, and then the bracket is hooked by a hook and pulled outwards, so that the bracket and the fuel cell 300 located thereon can be pulled out horizontally through the third opening 112 and placed on the lifting trolley, and then the fuel cell 300 can be disassembled from the bracket, and the operation is convenient.

[0073] Of course, if the fuel cell 300 is taken out by opening the first maintenance cover 212, the hook can also be hooked on the bracket, and the bracket and the fuel cell 300 located thereon can be lifted by a crane and moved out of the storage space 111, or moved out of the cab through the second opening 141.

[0074] Further, in some embodiments, the cab is integrally formed by welding a frame and panels. The cab frame 100 is welded by conventional profiles. The cab panels are thin plates, which are cut and bent from conventional metal thin plates. The thin plates are fixed on the cab frame 100 by bolts or welding to form the cab. This design has small investment and short cycle, and is particularly suitable for small batch production.

[0075] The cab frame 100 can be welded by conventional carbon steel profiles. The cab frame 100 can also be composed of conventional sheet metal stamping parts. The cab frame 100 can also be composed of aluminum profiles.

[0076] The cab panels can be stainless steel plates, which do not need to be painted and are resistant to corrosion and impact. The cab panels can also be panels made of other materials, such as aluminum plates, ordinary steel plates, etc.

[0077] For example, the fuel cell 300 can be arranged in the storage space 111 through the first opening 121 or the second opening 141. Figure 1 andFigure 2 As shown, the cab frame 100 is composed of six parts, namely a floor frame 110, a top frame 140, a first side frame 120, a second side frame 130, a rear frame 160 and a front frame 150. Each frame is welded by internal profiles, and the cab frame 100 is formed by welding or screwing. Of course, the cab frame 100 can also be formed by riveting.

[0078] As shown, Figures 3 to 6 The cab panels are thin plates, mainly composed of a floor panel 210, a top panel 240, a first side panel 220, a second side panel 230, a rear panel 260 and a front panel 250. The complete cab assembly is formed by welding or bolting the panels to the frame.

[0079] The second aspect of the utility model provides a vehicle which comprises the cab of any one of the above embodiments.

[0080] The vehicle provided by the embodiments of the present aspect has the cab of any one of the above embodiments, and thus has the beneficial effects of any one of the above embodiments, which will not be repeated here.

[0081] Further, in some embodiments, the hydrogen energy vehicle further comprises a vehicle chassis, an energy storage system, a power battery system and a cargo box. The cab is arranged on the vehicle chassis, and the cargo box is arranged on the vehicle chassis and located at the rear side of the cab. The energy storage system is arranged on the vehicle chassis and located below the cargo box. The power battery system is arranged between the cab and the cargo box.

[0082] The current conventional hydrogen energy heavy truck replaces the engine below the cab with a fuel cell 300, and then arranges the energy storage device between the cab and the cargo box. The power battery system is arranged below the cargo box, on both sides of the chassis beam, and is basically the same as the conventional fuel vehicle. However, such an arrangement occupies about 1.5 meters of length between the cargo box and the cab, which reduces the carrying capacity of the truck by about 1 / 5.

[0083] In the embodiments, the energy storage system is arranged on the vehicle chassis and located below the cargo box, and the power battery system is arranged between the cab and the cargo box. Since the volume of the power battery system is usually much smaller than that of the energy storage system, the space occupied by the on-board hydrogen energy system between the cab and the cargo box can be greatly reduced, thereby facilitating the extension of the length of the cargo box and improving the carrying capacity of the hydrogen energy vehicle.

[0084] In addition, the hydrogen energy vehicle is usually a heavy truck, such as a truck with a carrying capacity of more than 30 tons. Moreover, the hydrogen energy vehicle is usually used for long-distance transportation, which requires strong endurance. Therefore, the hydrogen storage tank in the energy storage system usually has a large volume, which can store enough hydrogen to provide power for a long distance. The volume of the power battery system is much smaller than that of the energy storage system, but in the case that the hydrogen in the energy storage system is used up, the power battery system needs to store the amount of electricity to provide power for the hydrogen energy vehicle, so the power battery system also has a certain volume.

[0085] In this embodiment, the power battery system is arranged between the cab and the cargo box, and the cab and the cargo box have a certain installation space, which facilitates the power battery system to reserve a certain volume, so that the power battery system has a large amount of electricity storage, thereby improving the endurance of the hydrogen energy vehicle.

[0086] The energy storage system can include a plurality of hydrogen storage tanks. The energy storage system stores hydrogen to supply the fuel cell 300 to generate electricity. The power battery system is used to store and release electricity. The electricity generated by the fuel cell 300 can be stored in the power battery system, and the power battery system can provide power for the hydrogen energy vehicle. Of course, the fuel cell 300 can also directly supply power to the hydrogen energy vehicle to provide power when the hydrogen energy vehicle is accelerating or climbing, etc. The specific power supply mode can be various, which will not be enumerated here.

[0087] Further, the energy storage system is distributed on both sides of the width direction of the vehicle chassis. The vehicle chassis bears the energy storage system on both sides, which not only increases the storage space of the energy storage system, but also facilitates to carry more hydrogen energy, thereby improving the endurance of the hydrogen energy vehicle.

[0088] Further, the back of the cab has a power battery storage area recessed into the interior of the cab, and part of the power battery system is arranged in the power battery storage area. The power battery system is moved forward into the power battery storage area, occupying part of the space of the original cab mounting area, which is conducive to extending the length of the cargo box and improving the carrying capacity.

[0089] It should be noted that in the traditional fuel truck, since the fuel cell 300 is arranged below the cab, the position of the original engine, the fuel cell 300 cannot be moved forward and will interfere with the parts such as the gear area, so that the area at the back of the cab is difficult to recess to form a power battery storage area. In this embodiment, since the fuel cell 300 is arranged inside the floor frame 110 of the cab frame 100, the fuel cell 300 can be moved forward compared with the position of the traditional engine, thereby facilitating the formation of the power battery storage area, and further helping to extend the length of the cargo box.

[0090] Further, the hydrogen energy vehicle further comprises a fuel cell 300 heat dissipation system arranged between the cab and the container, the fuel cell 300 heat dissipation system is arranged above the power battery system or on one side of the power battery system in the width direction of the vehicle chassis. Here, the fuel cell 300 heat dissipation system is arranged between the cab and the container, close to the fuel cell 300, which can shorten the connecting structure such as pipeline and reduce the cost. Moreover, the fuel cell 300 heat dissipation system is arranged above the power battery system or on one side of the power battery system in the width direction of the vehicle chassis, which facilitates heat dissipation without increasing the distance between the cab and the container, thereby facilitating the guarantee of the length of the container and the guarantee of the load capacity.

[0091] Further, in some embodiments, the vehicle includes but is not limited to a hydrogen energy heavy truck.

[0092] Although the embodiments of the present application have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. It should be understood that these modifications and variations will still fall within the spirit and scope of the embodiments of the present application defined by the claims.
