[0055] The embodiments of the present application will be described below in conjunction with Figures 1 to 12 The embodiments of the present application provide a cab and a hydrogen energy vehicle.

[0056] As shown in Figures 2 to 4 , the first aspect of the present application provides a cab, which comprises: a cab frame 100, the interior of the cab frame 100 has a driving side and a non-driving side distributed oppositely, a fuel cell mounting space 120 is arranged at the non-driving side, and the fuel cell mounting space 120 is used for mounting a fuel cell 200.

[0057] The cab provided by the embodiments of the present application sets the fuel cell 200 at the non-driving side inside the cab frame 100, since the space at the non-driving side inside the cab frame 100 is large, the fuel cell 200 can be conveniently accommodated, and the driver can drive the vehicle at the driving side without being affected.

[0058] Further, in some embodiments, as shown in Figure 2 and Figure 3 , the fuel cell mounting space 120 is located at the lower part of the non-driving side. In this way, the upper part of the non-driving side can be reserved for a certain space, so that in the case that the side of the cab frame 100 close to the non-driving side has a window, the light from the outside can pass through the space to enter the driving side, and the driver can also observe the external environment through the window outside the non-driving side, thereby providing good conditions for the safe driving of the driver.

[0059] In addition, a bunk bed (not shown in the figure) can also be arranged inside the cab frame 100 on the non-driving side, above the fuel cell mounting space 120, so that the space on the upper part of the non-driving side can also be used for the driver to lie down and rest, especially during long-distance transportation, which can improve the user experience of the driver. As an example, the bunk bed extends along the front-rear direction of the cab frame 100. In addition, the bunk bed can also be arranged below the window mentioned above, so as to avoid blocking the window.

[0060] Of course, in other embodiments, the fuel cell mounting space 120 can also be located on the upper part of the non-driving side.

[0061] In order to facilitate the maintenance or replacement of the fuel cell 200, further, in some embodiments, as shown in Figures 1 to 4 the cab further comprises an external maintenance cover 300 arranged on the outside of the cab frame 100 corresponding to the position of the fuel cell mounting space 120, a passage for removing the fuel cell 200 is left between the external maintenance cover 300 and the fuel cell mounting space 120, and when the external maintenance cover 300 is in an open state, the fuel cell mounting space 120 is in communication with the outside.

[0062] In these embodiments, since the fuel cell 200 is located in the fuel cell mounting space inside the cab frame 100, and cooperates with the external maintenance cover 300, when the fuel cell 200 needs to be maintained or replaced, the fuel cell 200 can be removed by opening the external maintenance cover 300, without the need to overturn the entire cab as in the traditional engine disassembly, which greatly facilitates the maintenance or replacement of the fuel cell 200.

[0063] In the related art, since the fuel cell 200 is located at the middle position below the cab, when the fuel cell 200 needs to be maintained or replaced, the cab needs to be turned forward by about 40° by a turnover mechanism first, so that the fuel cell 200 is exposed, the lines and pipelines of the fuel cell 200 are disconnected, the fixing bolts for fixing the fuel cell 200 are loosened, and then the fuel cell 200 can be lifted and taken down, which is very troublesome. In the present embodiment, without the need to overturn the cab or lift the fuel cell 200, only an external maintenance cover 300 that can be opened needs to be arranged on the non-driving side of the cab frame 100, which is simple in structure. When operating, the fuel cell 200 can be exposed by directly opening the external maintenance cover 300, the related pipelines and lines of the fuel cell 200 are disassembled, and after the corresponding fixing members are loosened, the fuel cell 200 can be horizontally pulled out and disassembled, which is convenient to operate.

[0064] In some embodiments, as shown in Figures 1 to 5As shown, the outer maintenance cover 300 is located at the outer side of the cab frame 100 in the width direction and close to the non-driving side. That is, the outer maintenance cover 300 is located at the side where the original co-driver door is located, and the outer side of the outer maintenance cover 300 has sufficient cover space, which is convenient for opening and also facilitates pulling out the fuel cell 200 outward.

[0065] In this case, when the fuel cell installation space 120 is located at the lower part of the non-driving side, the outer maintenance cover 300 can extend from the top of the cab frame 100 to the bottom of the cab frame 100 as the co-driver door in the related art. At this time, the window body can be directly arranged at the upper part of the outer maintenance cover 300, which is higher than the fuel cell installation space 120. As shown, Figure 1 and Figure 2 As shown, the outer maintenance cover 300 can also cover only the lower half of the cab frame 100 and extend downward from the middle part of the cab frame 100, corresponding to the fuel cell installation space 120. At this time, the outer side of the cab frame 100 close to the non-driving side in the width direction has a cab side plate 900, which is located above the outer maintenance cover 300, and the window body is arranged on the cab side plate 900.

[0066] In other embodiments, the outer maintenance cover 300 can also be arranged at the front side or the rear side of the cab frame 100. If the outer maintenance cover 300 is located at the front side of the cab frame 100, the fuel cell 200 will also be closer to the front side of the cab frame 100, which facilitates the taking and placing of the fuel cell 200. If the outer maintenance cover 300 is located at the rear side of the cab frame 100, in the case that the vehicle has a turnable cargo compartment, the cargo compartment can shield the outer maintenance cover 300, beautifying the appearance. Of course, in this case, the cargo compartment needs to be turned first before the outer maintenance cover 300 can be opened.

[0067] In some embodiments, one end of the outer maintenance cover 300 is rotationally connected with the cab frame 100. The rotational connection structure is generally simple and cost-saving.

[0068] Further, as shown, Figure 4 the outer maintenance cover 300 is connected with the cab frame 100 through a damper 400, so that the outer maintenance cover 300 can be kept in the open state under the damping action. Here, the damping action is used to keep the outer maintenance cover 300 open, so that the user does not need to hold the outer maintenance cover 300 when taking and placing the fuel cell 200, which is convenient for operation and can avoid the outer maintenance cover 300 from suddenly closing and injuring the user.

[0069] As an example, the damper 400 is a pneumatic cylinder or a hydraulic cylinder.

[0070] Or further, the cab further comprises a support rod (not shown in the figure), one end of the support rod is rotatably connected with the outer maintenance cover 300, and the other end of the support rod can be away from the outer maintenance cover 300 to prop up the outer maintenance cover 300 to keep it in an open state. Here, the support rod is used to prop up the outer maintenance cover 300, which can also prevent the outer maintenance cover 300 from closing suddenly. The support rod has simple structure, convenient processing, and low cost, and the use of the mechanical form of the support rod to prop up the outer maintenance cover 300 has high reliability.

[0071] Further, as shown in Figures 2 to 4 , the upper end of the outer maintenance cover 300 is rotatably connected with the cab frame 100, and the outer maintenance cover 300 is opened by turning from bottom to top. In operation, the outer maintenance cover 300 can be opened and then rotated upward to about 100°, and then kept in an open state by the air support of the damper 400, for example Figure 4 , the posture of the outer maintenance cover 300, and then the pipelines and lines related to the fuel cell 200 are disassembled, the bolts on the bracket 810 and the suspension 820 are loosened, and the fuel cell 200 can be pulled out and disassembled.

[0072] Of course, one end of the outer maintenance cover 300 in the horizontal direction can also be rotatably connected with the cab frame 100, and the outer maintenance cover 300 can be opened by turning left and right.

[0073] In other embodiments, the outer maintenance cover 300 is slidably connected with the cab frame 100, similar to the connection mode of the sliding door of a minivan. The connection mode of the outer maintenance cover 300 with the cab frame 100 is not limited to the above embodiments, as long as the outer maintenance cover 300 can be opened to facilitate the taking and placing of the fuel cell 200.

[0074] In some embodiments, the cab further comprises a locking assembly for locking the outer maintenance cover 300 on the cab frame 100. By locking the outer maintenance cover 300 on the cab frame 100 through the locking assembly, the outer maintenance cover 300 can be effectively prevented from being opened by mistake, and impurities such as dust or sewage from the outside can be prevented from entering the fuel cell installation space 120.

[0075] As an example, as shown in Figure 4 , the upper edge of the outer maintenance cover 300 is fixed to the cab frame 100 by a hinge 310, the outer maintenance cover 300 is opened by turning upward, and the locking assembly is arranged at the lower edge of the outer maintenance cover 300. Of course, the locking assembly can also be arranged at the edge in the width direction of the outer maintenance cover 300. Alternatively, the locking assembly and the hinge 310 are distributed at opposite ends of the outer maintenance cover 300.

[0076] As an example, as shown in Figure 4 , Figure 5 and Figure 6As shown, the locking assembly includes a locking tongue 510 and a latching part 520. One of the locking tongue 510 and the latching part 520 is disposed on the outer maintenance cover 300, and the other is disposed on the cab frame 100. The locking tongue 510 can extend and insert into the latching part 520 to achieve locking, and the locking tongue 510 can also move away from the latching part 520.

[0077] The locking assembly may also include a safety element that is movable in a first position and a second position. In the first position, the safety element prevents the latch 510 from disengaging from the latch portion 520. In the second position, the safety element moves away from the latch 510, allowing the latch 510 to disengage from the latch portion 520. Thus, the locking assembly can have two locks, ensuring the safe closure of the outer maintenance cover 300.

[0078] Specifically, such as Figures 4 to 6 As shown, the outer maintenance cover 300 is equipped with a rotatable handle 530, which is connected to the locking tongue 510. A switch 540 is provided on the outer maintenance cover 300 or the cab frame 100, which is connected to a safety component, or the two are integrated into one structure. When it is necessary to open the outer maintenance cover 300, the switch 540 is first triggered to move the safety component to the second position, unlocking one lock. Then, the handle 530 is pulled to move the locking tongue 510 away from the latching part 520, unlocking the second lock. Simultaneously, the user can also pull the outer maintenance cover 300 open via the handle 530, and the open state of the outer maintenance cover 300 is maintained by the air support of the damper 400, making operation convenient.

[0079] Furthermore, in some embodiments, such as Figure 11 As shown, the cab also includes an inner maintenance cover 600, which is located inside the cab frame 100 and on one side of the fuel cell installation space 120. When the inner maintenance cover 600 is open, the fuel cell installation space 120 is connected to the driving space 110 inside the cab frame 100.

[0080] In these embodiments, an inner maintenance cover 600 is provided inside the cab frame 100. When the fuel cell 200 needs to be repaired or replaced, the fuel cell 200 can be moved out to the driving space 110 simply by opening the inner maintenance cover 600, and then the fuel cell 200 can be moved out of the driving space 110. Compared with the related technology, which requires flipping the cab to expose the fuel cell 200, the replacement or repair of the fuel cell 200 is more convenient.

[0081] In this configuration, the cab may not have the aforementioned external maintenance cover 300, allowing the cab doors and non-cab doors on both sides of the cab to maintain a consistent and symmetrical appearance, resulting in a better aesthetic effect. Alternatively, the cab may have both the aforementioned external maintenance cover 300 and internal maintenance cover 600.

[0082] Further, the fuel cell mounting space 120 is located at the lower portion of the non-driving side, and the inner maintenance cover 600 is located above the fuel cell mounting space 120.

[0083] In this way, even if the inner maintenance cover 600 is arranged inside the cab frame 100, the fuel cell 200 can be taken out from inside the cab frame 100, and the fuel cell mounting space 120 does not block the window on the side of the cab frame 100 close to the non-driving side in the width direction, which facilitates the light from the outside to pass through the window to the driving side, and also facilitates the driver to observe the outside environment through the window, thereby providing good conditions for the driver to drive safely.

[0084] In addition, in this case, a bunk (not shown in the figure) can be arranged on the non-driving side inside the cab frame 100, and the bunk is provided with an opening, and the inner maintenance cover 600 is arranged at the opening in a switchable manner, so that the space at the upper portion of the non-driving side can also be used for the driver to lie down and rest.

[0085] Further, as shown in Figure 10 and Figure 12 , the cab further comprises a cab roof 700, which is detachably arranged at the top of the cab frame 100 and located above the inner maintenance cover 600, and a passage for the fuel cell 200 to move out is left between the cab roof 700 and the inner maintenance cover 600. When the fuel cell 200 is maintained or replaced, the cab roof 700 and the inner maintenance cover 600 can be opened, and then the fuel cell 200 can be hoisted out of the cab frame 100, which is convenient for taking and placing the fuel cell 200.

[0086] Figure 10 A top view of the vehicle is shown when the cab roof 700 is not detached. Figure 11 A top view of the vehicle is shown when the cab roof 700 is detached, from which the inner maintenance cover 600 can be seen. Figure 12 A top view of the vehicle is shown when the inner maintenance cover 600 and the cab roof 700 are both detached, from which the fuel cell mounting space 120 is exposed, and the fuel cell 200 can be hoisted and placed or taken out.

[0087] Further, in some embodiments, as shown in Figure 4 , Figures 7 to 9As shown in the drawings, the cab further comprises a fuel cell mounting structure 800 arranged in the fuel cell mounting space 120 and used for connecting with the fuel cell 200; wherein the fuel cell mounting structure 800 is detachably connected with the cab frame 100, and / or the fuel cell mounting structure 800 is used for being detachably connected with the fuel cell 200. In this way, when the fuel cell 200 is maintained or replaced, the fuel cell 200 can be removed alone or the fuel cell mounting structure 800 and the fuel cell 200 can be removed as a whole, so that the fuel cell 200 is prevented from being bumped or abraded.

[0088] Further, as shown in the drawings, Figures 7 to 9 The fuel cell mounting structure 800 comprises a bracket 810 fixed on the cab frame 100 by bolts, and a plurality of suspensions 820 arranged on the bracket 810 and used for supporting the fuel cell 200. The fuel cell 200 has good mounting stability.

[0089] As an example, as shown in the drawings, Figure 4 、 Figure 8 and Figure 9 The bracket 810 is substantially square, and the bracket 810 is provided with bolt holes 811 through which the bolts are inserted into the cab frame 100. The four suspensions 820 are fixed on the bracket 810, and the fuel cell 200 is fixed on the four suspensions 820. When the fuel cell 200 is maintained or replaced, the four bolts on the bracket 810 are first detached, then the bracket 810 is hooked by a hook and dragged outwards, so that the bracket 810 and the fuel cell 200 located thereon can be dragged out as a whole onto the lifting trolley, and then the fuel cell 200 can be detached from the bracket 810, which is convenient to operate.

[0090] Moreover, a special bracket 810 can be configured according to different fuel cells 200, and the fuel cell 200 is fixed on the suspensions 820 of the special bracket 810. The structure of the bracket 810 is not limited to the above example. For example, the bracket 810 can be a punched bracket 810 or a die-cast bracket 810.

[0091] As shown in the drawings, Figures 1 to 3 、 Figures 10 to 12 The second aspect embodiment of the utility model provides a hydrogen energy vehicle, including the cab of any one of above-embodiments.

[0092] The hydrogen energy vehicle provided by the embodiment has the cab of any one of the above embodiments, and has the beneficial effects of any one of the above embodiments, which will not be described herein.

[0093] 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.

[0094] The current conventional hydrogen energy heavy truck replaces the engine under the cab with a fuel cell, 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 causes the space between the cargo box and the cab to be occupied by the cargo box by about 1.5 meters, resulting in a reduction of about 1 / 5 of the carrying capacity of the truck.

[0095] In the embodiment, 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 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.

[0096] 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 and requires strong endurance. Therefore, the hydrogen storage tank in the energy storage system usually has a large volume to 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 enough power to provide power for the hydrogen energy vehicle. Therefore, the power battery system also has a certain volume.

[0097] In the embodiment, the power battery system is arranged between the cab and the cargo box. The cab and the cargo box have a certain installation space, which facilitates the power battery system to retain a certain volume, so that the power battery system has a large power storage capacity, thereby improving the endurance of the hydrogen energy vehicle.

[0098] The energy storage system can include a plurality of hydrogen storage tanks. The energy storage system stores hydrogen to supply the fuel cell 200 to generate power. The power battery system is used to store and release power. The power generated by the fuel cell 200 can be stored in the power battery system to provide power for the hydrogen energy vehicle. Of course, the fuel cell 200 can also directly supply power to the hydrogen energy vehicle to provide power in the case of acceleration or climbing, etc. The specific power supply mode can be various, which will not be enumerated here.

[0099] 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 the loading of more hydrogen energy, thereby improving the endurance of the hydrogen energy vehicle.

[0100] 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. Moving the power battery system forward into the power battery storage area occupies part of the space of the original cab mounting area, which facilitates the extension of the length of the cargo box and the increase of the cargo capacity.

[0101] It should be noted that in a traditional fuel truck, since the fuel cell is arranged below the cab, the fuel cell cannot be moved forward due to interference with components such as the gear area, making it difficult to recess the area at the back of the cab to form a power battery storage area. In the present embodiment, since the fuel cell is arranged inside the cab frame, the fuel cell can be moved forward compared to the position of the traditional engine, thereby facilitating the formation of a power battery storage area, which in turn helps to extend the length of the cargo box.

[0102] Further, the hydrogen energy vehicle further comprises a fuel cell cooling system arranged between the cab and the cargo box, and the fuel cell cooling 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. Arranging the fuel cell cooling system between the cab and the cargo box and close to the fuel cell 200 can shorten the connecting structure such as the pipeline and reduce the cost. Moreover, arranging the fuel cell cooling system above the power battery system or on one side of the power battery system in the width direction of the vehicle chassis facilitates cooling without increasing the distance between the cab and the cargo box, thereby facilitating the length of the cargo box and the cargo capacity.

[0103] Further, in some embodiments, the hydrogen energy vehicle includes but is not limited to a heavy truck.

[0104] 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 as defined by the claims.
