[0046] The embodiment of the present application provides a front cabin structure and a vehicle including the front cabin structure, wherein it should be noted that the vehicle in the present application may refer to a large car, a small car, a special-purpose vehicle, etc. For example, according to the vehicle type, the vehicle in the present application may be a sedan, a bus, a truck, an off-road vehicle, a multi-purpose vehicle (MPV) or other vehicle types. For example, the vehicle may be an electric vehicle / electric vehicle, a pure electric vehicle, a hybrid vehicle, an extended-range electric vehicle, a plug-in hybrid vehicle, a new energy vehicle, and any vehicle with a front trunk.

[0047] A vehicle is generally provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0051] In order to solve the above problems, the embodiment of the present application provides a front cabin structure, by arranging a mounting bracket on the front crossbeam, and making the two ends of the mounting bracket protrude from the two sides of the front crossbeam, so that the front trunk is connected to the parts of the mounting bracket protruding from the two sides of the front crossbeam, so that the fixing points of the front trunk can be located on both sides of the front crossbeam. It can effectively increase the distribution range of the fixing points of the front trunk, and effectively increase the fixing and supporting area of ​​the bottom of the front trunk. It can effectively improve the uniformity of the force on the front trunk, and can effectively reduce or avoid the cracking of the front trunk due to uneven force during use, thereby effectively improving the firmness and stability of the fixed support of the front trunk.

[0052] The front cabin structure provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

Figure 3 A schematic diagram of the structure of a front crossbeam provided in an embodiment of the present application is shown in FIG. Figure 4 A schematic diagram of the structure of a front trunk provided in an embodiment of the present application is shown in FIG. Figure 5 A schematic diagram of the structure of a front trunk provided in a vehicle according to an embodiment of the present application.

[0054] The present application provides a front cabin structure 100, which can be used in a vehicle, for example, can be installed at the front end (i.e., the front of the vehicle), see Figure 1 and Figure 2 As shown, the front cabin structure 100 may include at least two front longitudinal beams 110, and the at least two front longitudinal beams 110 may be arranged in parallel and at intervals. For example, the number of the front longitudinal beams 110 may be two, three or four, etc. In the embodiment of the present application, the number of the front longitudinal beams 110 is two as an example for explanation, and the front longitudinal beams 110 may extend from the front of the vehicle toward the rear of the vehicle, and the two front longitudinal beams 110 may be installed on both sides of the front cabin of the vehicle.

[0055] Combination Figure 3 As shown, the front cabin structure 100 may further include a front cross beam 120, which may be located between at least two front longitudinal beams 110, and the two ends of the front cross beam 120 may be connected to the front longitudinal beams 110 respectively, so that the two ends of the front cross beam 120 may be installed and fixed by the front longitudinal beams 110.

[0056] See also Figure 2 and Figure 3As shown, the front cabin structure 100 may further include a plurality of mounting brackets 130, which may be spaced apart on the front cross beam 120 and connected to the front cross beam 120. The extending direction of the mounting brackets 130 may be set at an angle to the extending direction of the front cross beam 120. The mounting brackets 130 may protrude from both sides of the front cross beam 120, and the mounting brackets 130 may be connected to the front cross beam 120. Figure 4 and Figure 5 As shown, the front trunk 140 can be located on the front cross beam 120, and the front trunk 140 can be connected to the portion of the mounting bracket 130 protruding from the front cross beam 120. That is, the fixing points of the front trunk 140 are located on both sides of the front cross beam 120, which can effectively increase the coverage area of ​​the mounting points of the front trunk 140, and can effectively increase the fixing area of ​​the front trunk 140, thereby effectively improving the firmness and stability of the fixing of the front trunk 140.

[0057] For example, the angle between the extension direction of the mounting bracket 130 and the extension direction of the front cross beam 120 can be greater than or equal to 60° and less than or equal to 90°. In this way, under the premise that the length of the mounting bracket 130 is constant, the distance between the two ends of the mounting bracket 130 and the two sides of the front cross beam 120 can be increased, which helps to increase the distribution range of the fixing points of the front trunk 140 in the direction of the front longitudinal beam 110, thereby increasing the distribution range of the fixing points of the front trunk 140.

[0058] In the embodiment of the present application, the mounting bracket 130 is arranged on the front cross beam 120, and the two ends of the mounting bracket 130 protrude from the two sides of the front cross beam 120, so that the front trunk 140 is connected to the parts of the mounting bracket 130 protruding from the two sides of the front cross beam 120, so that the fixing points of the front trunk 140 can be located on both sides of the front cross beam 120. It can effectively increase the distribution range of the fixing points of the front trunk 140, and effectively increase the fixing and supporting area of ​​the bottom of the front trunk 140. It can effectively improve the uniformity of the force on the front trunk 140, and can effectively reduce or avoid the cracking of the front trunk 140 due to uneven force during use, thereby effectively improving the firmness and stability of the fixing support of the front trunk 140.

[0059] In the embodiment of the present application, the extension direction of the mounting bracket 130 may be perpendicular to the extension direction of the front cross beam 120 , that is, the angle between the extension direction of the mounting bracket 130 and the extension direction of the front cross beam 120 is equal to 90°. In other words, the extension direction of the mounting bracket 130 is consistent with the extension direction of the front longitudinal beam 110 .

[0060] In this way, under the premise that the length of the mounting bracket 130 is certain, the distance between the two ends of the mounting bracket 130 and the two sides of the front cross beam 120 can be made relatively larger, which can effectively increase the distribution range of the fixing points of the front trunk 140 in the direction of the front longitudinal beam 110, thereby effectively increasing the distribution range of the fixing points of the front trunk 140 and improving the firmness and reliability of the fixation of the front trunk 140.

[0061] Moreover, by making the extension direction of the mounting bracket 130 perpendicular to the extension direction of the front cross beam 120, the tilting or tipping of the mounting bracket 130 relative to the front cross beam 120 can be reduced or avoided, which helps to improve the reliability and stability of the connection between the mounting bracket 130 and the front cross beam 120, thereby effectively improving the stability and firmness of the installation of the front trunk 140.

[0062] For example, in the embodiment of the present application, the number of the mounting brackets 130 may be 3, 4, or 5. Preferably, the mounting brackets 130 may be as follows: Figure 2 and Figure 3 As shown in the figure, there are three mounting brackets 130 which can be spaced apart on the front cross beam 120 as shown in the figure. This can effectively disperse the stress points of the front trunk 140 and improve the uniformity of the stress on the front trunk 140, thereby effectively improving the firmness and reliability of the fixation of the front trunk 140.

[0063] Figure 6 A schematic diagram of the structure of a mounting bracket connected to a front crossbeam provided in an embodiment of the present application.

[0064] See also Figure 6 As shown, the mounting bracket 130 may include a first connection portion 131 and second connection portions 132 located on both sides of the first connection portion 131. The first connection portion 131 may be located at the bottom of the front cross beam 120 and connected to the front cross beam 120. For example, the first connection portion 131 and the front cross beam 120 may be connected by bolt fasteners. This may facilitate assembly and disassembly between the mounting bracket 130 and the front cross beam 120.

[0065] The second connection portion 132 may be located on both sides of the front cross beam 120, and the upper surface of the second connection portion 132 may be flush with the upper surface of the front cross beam 120, and the bottom of the front trunk 140 may be connected to the second connection portion 132. For example, the bottom of the front trunk 140 may contact the upper surface of the second connection portion 132, and the front trunk 140 and the second connection portion 132 may be connected by bolt fasteners.

[0066] Since the upper surface of the second connection portion 132 is flush with the upper surface of the front cross beam 120, when the front trunk 140 is connected to the upper surface of the second connection portion 132, the upper surface of the front cross beam 120 can also contact the bottom of the front trunk 140, so that the front cross beam 120 can support the front trunk 140. In this way, the support area of ​​the bottom of the front trunk 140 can be effectively increased, and the firmness and reliability of the fixing of the front trunk 140 can be improved.

[0067] Figure 7 A schematic structural diagram of the connection between a connecting member and a front longitudinal beam provided in an embodiment of the present application.

[0068] See also Figure 7 As shown, the front cabin structure 100 may further include a connector 150 , which may be fixedly connected to the front longitudinal beam 110 , and both ends of the front cross beam 120 may be detachably connected to the connector 150 , and both ends of the front cross beam 120 may be connected to the front longitudinal beam 110 via the connector 150 .

[0069] For example, during the assembly process, the connector 150 may be first fixedly connected to the front longitudinal beam 110, and then the front cross beam 120 may be connected to the connector 150, so that the front cross beam 120 and the front longitudinal beam 110 may be connected via the connector 150. This may facilitate the connection between the front cross beam 120 and the front longitudinal beam 110, and help improve the reliability and stability of the connection between the front cross beam 120 and the front longitudinal beam 110.

[0070] Continue to see Figure 7 As shown, the connecting member 150 may include a third connecting portion 151 and a fourth connecting portion 152 that are integrally formed and perpendicular to each other. The third connecting portion 151 may be fixedly connected to the front longitudinal beam 110, and the fourth connecting portion 152 may be detachably connected to the front cross beam 120. For example, the connecting member 150 may be a stamping part, and the third connecting portion 151 and the fourth connecting portion 152 may be formed into a mutually perpendicular structure through a stamping process. The third connecting portion 151 may be fixedly connected to the inner side of the front longitudinal beam 110, and the fourth connecting portion 152 may be connected to the upper surface of the front cross beam 120.

[0071] This can effectively improve the firmness and reliability of the connection between the third connection part 151 and the fourth connection part 152, help improve the overall structural strength and rigidity of the connecting member 150, and thus effectively improve the firmness and reliability of the connection between the front cross beam 120 and the front longitudinal beam 110.

[0072] Continue to see Figure 7As shown, the connector 150 may further include a reinforcing portion 153, which may be located between the third connector 151 and the fourth connector 152, and one end of the reinforcing portion 153 may be connected to the third connector 151, and the other end may be connected to the fourth connector 152. The reinforcing portion 153 may play a supporting role between the third connector 151 and the fourth connector 152, and may effectively reduce or avoid deformation of the connector 150. The structural strength of the connector 150 may be effectively improved, and the overall structural stability of the connector 150 may be improved, thereby effectively improving the reliability and stability of the connection between the front cross beam 120 and the front longitudinal beam 110.

[0073] In the embodiment of the present application, the front longitudinal beam 110 can be welded to the connecting member 150, and the front cross beam 120 can be detachably connected to the connecting portion by bolt fasteners. The welding connection can improve the firmness and reliability of the connection between the front longitudinal beam 110 and the connecting member 150, and can effectively reduce or avoid the separation between the connecting member 150 and the front longitudinal beam 110.

[0074] The bolt fasteners can facilitate the assembly and disassembly between the front cross beam 120 and the connecting member 150 , and can improve the operability of the connection between the front cross beam 120 and the front longitudinal beam 110 .

[0076] See also Figure 8 As shown, the front cross beam 120 may be provided with a first mounting hole 121, the connecting member 150 may be provided with a second mounting hole (not shown in the figure), and the bolt fastener may pass through the first mounting hole 121 and the second mounting hole in sequence, so that the front cross beam 120 and the connecting member 150 are connected by the bolt fastener. Through the cooperation of the bolt fastener with the first mounting hole 121 and the second mounting hole, the front cross beam 120 and the connecting member 150 can be detachably connected, which can effectively improve the firmness and reliability of the connection between the front cross beam 120 and the connecting member 150.

[0077] Continue to see Figure 8 As shown, the front cabin structure 100 may further include a supporting sleeve 160, and the front cross beam 120 may be a hollow structure having a cavity 122 therein. For example, the front cross beam 120 may be a profile structure, such as an aluminum alloy profile, having a cavity 122 therein.

[0078] The support sleeve 160 may be located in the cavity 122 of the front cross beam 120, and the support sleeve 160 may be coaxially arranged with the first mounting hole 121. For example, the first mounting hole 121 may pass through the top and bottom of the front cross beam 120, and the support sleeve 160 may be located between the top and bottom of the front cross beam 120 and coaxially arranged with the first mounting hole 121, that is, the interior of the support sleeve 160 is connected with the first mounting hole 121.

[0079] During the connection process of the bolt fastener, the bolt fastener can pass through the first mounting hole 121 and the interior of the support sleeve 160 to achieve connection with the connector 150. The support sleeve 160 can provide rigid support for the front cross beam 120, which can effectively improve the structural strength and rigidity of the front cross beam 120. The bending or deformation of the front cross beam 120 is reduced or avoided, thereby effectively improving the overall structural stability and reliability of the front cabin structure 100.

[0080] Continue to see Figure 8 As shown, the inner wall of the front cross beam 120 may also have a plurality of limiting protrusions 123, and the plurality of limiting protrusions 123 may be arranged around the peripheral side of the support sleeve 160, and the limiting protrusions 123 are used to provide radial limiting for the support sleeve 160. The limiting protrusions 123 may reduce or prevent the support sleeve 160 from moving or deflecting in the front cross beam 120, and may effectively improve the reliability and stability of the support sleeve 160 arranged inside the front cross beam 120, thereby effectively improving the structural stability of the front cross beam 120.
