[0037] The following combination Figures 1-6 The front nacelle bracket 10 , the thermoelectric hybrid power system and the vehicle according to the embodiments of the present invention are described in detail.

[0038] Reference Figure 1-Figure 3 As shown, a front nacelle support 10 according to an embodiment of the present invention comprises a fixing plate 1, a support leg 2, and a valve support 3. The fixing plate 1 defines a through hole 11 for bypassing the pipeline. The fixing plate 1 has a fixing surface 12 and a connecting surface 13, which are opposite to each other. The fixing surface 12 is suitable for fixing a hydrogen fuel cell 20. One end of the support leg 2 is connected to the connecting surface 13, and the other end of the support leg 2 is suitable for connecting to a hydrogen powertrain 30. The valve support 3 is fixedly connected to the connecting surface 13 and is suitable for fixing the valve body of the hydrogen powertrain 30. The valve body can be a three-way valve suitable for controlling the large and small circulation of the coolant in the hydrogen powertrain 30, and the pipeline can be a pipeline for supplying gas to the hydrogen fuel cell 20.

[0039] Reference Figure 1-Figure 3 As shown, in the up and down directions, the upper surface of the fixing plate 1 is the fixing surface 12, and the lower surface of the fixing plate 1 is the connecting surface 13. The upper end of the supporting leg 2 and the valve bracket 3 are both connected to the connecting surface 13, and the lower end of the supporting leg 2 is connected to the hydrogen powertrain 30, so that the front cabin bracket 10 is installed and fixed to the hydrogen powertrain 30, and the hydrogen fuel cell 20 can be installed and fixed to the fixing surface 12. Through the front cabin bracket 10, the hydrogen powertrain 30 and the hydrogen fuel cell 20 can be fixedly connected, and both the hydrogen powertrain 30 and the hydrogen fuel cell 20 can be arranged in the front cabin.

[0040] It can be understood that the fixed plate 1 is provided with an avoidance through-hole 11, through which the pipeline can directly pass through the fixed plate 1 and be connected to the hydrogen fuel cell 20, so as to avoid the pipeline from making a detour to avoid the fixed plate 1, thereby shortening the length of the pipeline and reducing the layout space occupied by the pipeline in the front cabin, effectively solving the difficulty of insufficient layout space when the hydrogen powertrain 30 and the hydrogen fuel cell 20 are arranged in the front cabin, facilitating the layout of the hydrogen powertrain 30 and the hydrogen fuel cell 20 in the front cabin, and at the same time reducing the weight of the vehicle, saving the cost of the vehicle, and making the overall structure of the hydrogen fuel cell 20, the front cabin bracket 10 and the hydrogen powertrain 30 compact, which is conducive to improving the space utilization of the front cabin. In addition, the shorter pipeline can also reduce the pressure loss during the transmission of gas through the pipeline to the hydrogen fuel cell 20, thereby helping to improve the gas supply efficiency and improve the performance of the hydrogen fuel cell 20.

[0041] According to the front cabin bracket 10 of the embodiment of the present utility model, the hydrogen fuel cell 20 can be installed and fixed to the hydrogen powertrain 30 through the front cabin bracket 10 to form a whole. The hydrogen fuel cell 20 and the hydrogen powertrain 30 can be arranged in the front cabin as a whole. The fixing plate 1 is provided with an avoidance through-hole 11, and the pipeline can pass through the fixing plate 1 to be connected to the hydrogen fuel cell 20, which is beneficial to shorten the length of the pipeline and reduce the layout space occupied by the pipeline in the front cabin, so as to facilitate the layout of the hydrogen powertrain 30 and the hydrogen fuel cell 20 in the front cabin.

[0042] In some embodiments of the present invention, at least one of the fixed plate 1 and the hydrogen powertrain 30 is detachably connected to the support leg 2, that is, the fixed plate 1 is detachably connected to the support leg 2, or the hydrogen powertrain 30 is detachably connected to the support leg 2, or both the fixed plate 1 and the hydrogen powertrain 30 are detachably connected to the support leg 2.

[0043] It can be understood that when the fixing plate 1 is detachably connected to the support leg 2, the fixing plate 1 and the support leg 2 can be manufactured separately, which is beneficial to reducing the difficulty of processing and manufacturing the front cabin bracket 10. When the hydrogen powertrain 30 is detachably connected to the support leg 2, the hydrogen powertrain 30 can be maintained by removing the support leg 2 from the hydrogen powertrain 30 to remove the front cabin bracket 10 as a whole from the hydrogen powertrain 30, avoiding interference between tools used to maintain the hydrogen powertrain 30 and the front cabin bracket 10, so as to facilitate maintenance of the hydrogen powertrain 30.

[0044] In some embodiments of the present invention, referring to Figure 1As shown, the support leg 2 includes: a first support plate 21, a second support plate 22, and a connecting support plate 23. The first support plate 21 is provided with at least one first connecting hole 211, and each first connecting hole 211 is detachably connected to the fixing surface 12 through a corresponding first fastener. The second support plate 22 is provided with at least one second connecting hole 221, and each second connecting hole 221 is suitable for being detachably connected to the hydrogen powertrain 30 through a corresponding second fastener. The connecting support plate 23 is connected between the first support plate 21 and the second support plate 22, wherein the first fastener and the second fastener can be screws, and the first fastener and the second fastener can also be fastening bolts and fastening nuts.

[0045] It can be understood that the first support plate 21 is conducive to increasing the connection area between the support leg 2 and the fixed surface 12, thereby helping to improve the connection strength between the support leg 2 and the fixed surface 12, and the second support plate 22 is conducive to increasing the connection area between the support leg 2 and the hydrogen powertrain 30, thereby helping to improve the connection strength between the support leg 2 and the hydrogen powertrain 30, and helping the support leg 2 to reliably support the fixed plate 1.

[0046] The first connection hole 211 of the first support plate 21 is detachably connected to the fixing surface 12 through the corresponding first fastener, and the second connection hole 221 of the second support plate 22 is detachably connected to the hydrogen powertrain 30 through the corresponding second fastener, so that both the fixing plate 1 and the hydrogen powertrain 30 can be detachably connected to the support leg 2, which is beneficial to reducing the processing and manufacturing difficulty of the front cabin bracket 10. When the hydrogen powertrain 30 needs maintenance, the front cabin bracket 10 can be removed from the hydrogen powertrain 30 to avoid interference between tools used to maintain the hydrogen powertrain 30 and the front cabin bracket 10, so as to facilitate the maintenance of the hydrogen powertrain 30.

[0047] Reference Figure 1 As shown, in the vertical direction, the second support plate 22 is spaced apart from the first support plate 21. The second support plate 22 and the first support plate 21 are connected by the connecting support plate 23, which can raise the height of the fixed plate 1. When the front cabin bracket 10 is installed and fixed to the hydrogen powertrain 30, the risk of interference between the fixed plate 1 and the hydrogen powertrain 30 can be reduced. The second support plate 22 and the first support plate 21 can be arranged opposite each other, or the second support plate 22 and the first support plate 21 can be arranged staggered. When the second support plate 22 and the first support plate 21 are arranged opposite each other, force transmission is facilitated, which helps the support legs 2 to reliably support the fixed plate 1.

[0048] In some embodiments of the present invention, referring to Figure 1 and Figure 4As shown, the first connecting holes 211 are multiple in number, and the multiple first connecting holes 211 are located on both sides of the connecting support plate 23. The second connecting holes 221 are multiple in number, and the multiple second connecting holes 221 are located on both sides of the connecting support plate 23. When the support leg 2 is connected with the fixed plate 1, the multiple first connecting holes 211 can be connected with the fixed surface 12 through multiple corresponding first fasteners to form multiple sets of fastening cooperation, which is conducive to improving the strength of the connection between the support leg 2 and the fixed plate 1, thereby being conducive to improving the structural strength of the front engine compartment support 10. When the front engine compartment support 10 is installed and fixed to the hydrogen power assembly 30 through the support leg 2, the multiple second connecting holes 221 can be connected with the hydrogen power assembly 30 through multiple corresponding second fasteners to form multiple sets of fastening cooperation, which is conducive to improving the strength of the connection between the support leg 2 and the hydrogen power assembly 30, thereby being conducive to improving the stability and reliability of the connection between the front engine compartment support 10 and the hydrogen power assembly 30.

[0049] It can be understood that the multiple first connecting holes 211 and the multiple second connecting holes 221 are located on both sides of the connecting support plate 23, so that the first support plate 21 is uniformly stressed on both sides of the connecting support plate 23, and the second support plate 22 is uniformly stressed on both sides of the connecting support plate 23, thereby reducing the risk of local deformation of the first support plate 21 and the second support plate 22, and being conducive to improving the structural stability of the support leg 2, so as to facilitate the stable and reliable installation of the fixed plate 1 to the hydrogen power assembly 30 through the support leg 2.

[0050] In some embodiments of the present application, referring to Figure 4 As shown, the support leg 2 further comprises: an exhaust support plate 24, the exhaust support plate 24 is connected with the connecting support plate 23, and the exhaust support plate 24 is adapted to fix an exhaust pipe of the hydrogen power assembly 30 to support and fix the exhaust pipe. By integrating the exhaust support plate 24 for fixing the exhaust pipe into the support leg 2, the integration degree of the front engine compartment support 10 is improved. The exhaust support plate 24 and the connecting support plate 23 can be connected by welding, and the exhaust pipe can be fixed to the exhaust support plate 24 by welding.

[0051] As shown in Figure 4 The exhaust support plate 24 is configured as an arc-shaped plate, which has good bending and torsional resistance to improve the structural strength of the exhaust support plate 24 and facilitate the reliable support and fixation of the exhaust pipe by the exhaust support plate 24.

[0052] In some embodiments, the inner diameter of the exhaust support plate 24 can be the same as the outer diameter of the exhaust pipe, and the inner wall of the exhaust support plate 24 can be in close contact with the outer wall of the exhaust pipe, which is conducive to increasing the connection area between the exhaust support plate 24 and the exhaust pipe, thereby improving the connection strength between the exhaust support plate 24 and the exhaust pipe.

[0053] In some embodiments of the present invention, there are multiple support legs 2, which are spaced apart. The multiple support legs 2 can support the fixing plate 1 at multiple locations on the fixing plate 1 to avoid local stress concentration on the fixing plate 1, thereby reducing the risk of local deformation of the fixing plate 1 and improving the structural stability of the front cabin bracket 10. The top surface of the first support plate 21 of each support leg 2 is at a consistent height. When the fixing plate 1 is mounted and fixed to the multiple support legs 2, the fixing plate 1 can be parallel to the horizontal plane, facilitating the installation of the hydrogen fuel cell 20. After the hydrogen fuel cell 20 is mounted and fixed to the fixing plate 1, the hydrogen fuel cell 20 can be prevented from tilting, thereby achieving a stable installation of the hydrogen fuel cell 20.

[0054] In some embodiments of the present invention, referring to Figure 5 As shown, the valve bracket 3 includes: a first bracket plate 31, a second bracket plate 32 and a connecting bracket plate 33. The first bracket plate 31 is provided with at least one third connecting hole 311, and each third connecting hole 311 is detachably connected to the connecting surface 13 through a corresponding third fastener. The second bracket plate 32 is arranged opposite to the first bracket plate 31, and the connecting bracket plate 33 is connected between the first bracket plate 31 and the second bracket plate 32.

The second bracket plate 32 and / or the connecting bracket plate 33 are provided with at least one fourth connecting hole 321, and each fourth connecting hole 321 is suitable for being detachably connected to the valve body through a corresponding fourth fastener.

[0055] It can be understood that the valve bracket 3 can be installed and fixed to the fixed plate 1 by connecting the corresponding third connecting hole 311 and the connecting surface 13 through the third fastener. The second bracket plate 32 is arranged opposite to the first bracket plate 31, and the connecting bracket plate 33 is connected between the first bracket plate 31 and the second bracket plate 32, so that the valve bracket 3 can be constructed as a "U"-shaped bracket with good bending and torsion resistance to enhance the structural strength of the valve bracket 3, so that the valve body can be stably and reliably installed and fixed to the valve bracket 3. The valve body is arranged in the valve mounting groove 34, and the valve bracket 3 can protect the valve body on the outside of the valve body to reduce the risk of the valve body being hit.
