To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this disclosure.

[0003] With the development of vehicle electrification, some non-load-bearing off-road vehicles are gradually adopting battery drive. The main function of the front engine compartment of an electric off-road vehicle is to provide mounting support for the hood, air conditioning system accessories, electrical system accessories, and storage mechanisms. Compared with non-load-bearing off-road vehicles powered by gasoline engines, the front engine compartment of a non-load-bearing electric off-road vehicle needs to bear a heavier load. Currently, the strength and rigidity of the non-load-bearing front engine compartment often require a trade-off between lightweighting and structural strength, making it difficult to provide a better mounting structure for the hood system, air conditioning system accessories, electrical system accessories, and storage mechanisms, resulting in poor overall stability. Summary of the Invention

[0007] The wheel arch assembly has two sets spaced apart along the width of the vehicle body. The two sets of wheel arch assemblies are fixedly connected to the front bulkhead assembly and the cab frame at intervals. The wheel arch assembly includes a first structural beam and a second structural beam extending along the length of the vehicle body. The first structural beam and the second structural beam are hollow.

[0008] The first crossbeam and the second crossbeam are arranged parallel to each other and spaced apart between the two sets of wheel cover assemblies, and the two ends of the first crossbeam and the second crossbeam are respectively fixed on the two sets of wheel cover assemblies;

The mounting positions are provided with two upright plates arranged along the width direction of the vehicle body, and the two upright plates are respectively fixedly connected to the transition plate, the first structural beam, and the first structural beam to enclose and form a closed space.

[0013] In an optional embodiment, the mounting position is provided with two sets of mounting points, and the first crossbeam and the second crossbeam are respectively fixed to the two sets of mounting points by fasteners.

[0014] In an optional implementation, on each set of wheel shroud assemblies, the distance between the two sets of mounting points is less than the distance between the two uprights.

[0015] In an optional embodiment, the first crossbeam and / or the second crossbeam are provided with L-shaped mounting brackets, and the first crossbeam and / or the second crossbeam are provided with a reinforcing section in the middle with a thickness greater than that at the ends.

[0019] Compared with the prior art, the advantages of this application are:

[0020] The front engine compartment structure of this application includes two sets of wheel arch assemblies spaced apart along the width of the vehicle body. The two sets of wheel arch assemblies are fixedly connected to the front bulkhead assembly and the cab frame at intervals.

The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

Figure 2 This application provides a structural schematic diagram of 100 locations in the wheel arch assembly.

Figure 7 A structural schematic diagram of the hinge mounting component 203 is provided for an embodiment of this application.

[0032] like Figure 1 , Figure 2 As shown, a non-load-bearing forward engine compartment structure includes a wheel arch assembly 100, a first crossbeam 201, a second crossbeam 202, and a hinge mounting component 203, wherein:

[0033] Two sets of wheel arch assemblies 100 are spaced apart along the width of the vehicle body. The two sets of wheel arch assemblies 100 are fixedly connected to the front bulkhead assembly 401 and the cab frame 402 at intervals. Each wheel arch assembly 100 includes a first structural beam 101 and a second structural beam 102 extending along the length of the vehicle body. The first structural beam 101 and the second structural beam 102 are hollow and extend along the length of the vehicle body, providing a structural foundation in the front engine compartment area. After being fixedly connected to the front bulkhead assembly 401 and the cab frame 402, the structural arrangement on both sides of the front engine compartment area is maintained.

[0034] like Figure 3 , Figure 4 As shown, the first crossbeam 201 and the second crossbeam 202 are arranged parallel to each other and spaced apart between the two sets of wheel arch assemblies 100. The first crossbeam 201 and the second crossbeam 202 are respectively fixed at both ends on the two sets of wheel arch assemblies 100. The first crossbeam 201 and the second crossbeam 202 are arranged parallel to each other and spaced apart, so that the first crossbeam 201 and the second crossbeam 202 maintain the same distance and are respectively fixedly connected to the two sets of wheel arch assemblies 100. This makes the two wheel arch assemblies 100 and the first crossbeam 201 and the second crossbeam 202 together form a relatively stable relative state, so as to maintain a stable relative distance between the two wheel arch assemblies 100 and provide a mounting base, thereby improving the spatial layout flexibility of the front cabin.

[0035] like Figure 1 , Figure 2 As shown, there are two hinge mounting pieces 203, which are arranged between the two wheel arch assemblies 100 and fixedly connected to the two wheel arch assemblies 100 respectively. The hinge mounting piece 203 is provided with a mounting surface for mounting the hood hinge. The hinge mounting piece 203 is fixedly arranged between the wheel arch assemblies 100. The wheel arch assembly 100 provides the mounting base for the hinge mounting piece 203, and the hinge mounting piece 203 with higher integration can be assembled inside the front engine compartment, reducing the need for other beam structures for installation.

[0036] In an optional embodiment, the working principle of the front engine compartment structure in this application is as follows: It includes two sets of wheel arch assemblies 100 spaced apart along the width of the vehicle body. The two sets of wheel arch assemblies 100 are fixedly connected to the front bulkhead assembly 401 and the cab frame 402 at intervals. Each wheel arch assembly 100 includes a first structural beam 101 and a second structural beam 102 extending along the length of the vehicle body. The first structural beam 101 and the second structural beam 102 are hollow. A first crossbeam 201 and a second crossbeam 202 are arranged parallel to each other and spaced apart between the two sets of wheel arch assemblies 100. The two ends of the first crossbeam 201 and the second crossbeam 202 are respectively fixedly mounted on the two sets of wheel arch assemblies 100. Two hinge mounting parts 203 are arranged between the two wheel arch assemblies 100 and respectively connected to… Two wheel arch assemblies 100 are fixedly connected. The hinge mounting component 203 is provided with a mounting surface for mounting the hood hinge. In actual arrangement, the structural strength of the wheel arch assembly 100 itself is improved by the first structural beam 101 and the second structural beam 102. Furthermore, by setting parallel first crossbeam 201 and second crossbeam 202 to be fixed on the two sets of wheel arch assemblies 100 respectively, the correlation and stability between structural components are further improved, maintaining the structural strength of the wheel arch assembly 100 after forming a whole. The hinge mounting component 203 is arranged on the wheel arch assembly 100 to provide the mounting base for the hood hinge. Under the premise of reliable overall structural strength, the additional hood mounting structure is avoided and the mounting structure is re-set in the front cabin, improving overall reliability and space utilization.

[0037] like Figure 2 , Figure 3 As shown, in an optional embodiment, the cross-sections of the first structural beam 101 and the second structural beam 102 are U-shaped along the width direction of the vehicle body. By arranging the cross-sections, the structural strength of the first structural beam 101 and the second structural beam 102 is improved in the width direction of the vehicle body. Since the connection and fixation of the first structural beam 101 and the second structural beam 102 are fixedly connected to the front bulkhead assembly 401 and the cab frame 402 at the same time, the end of the first structural beam 101 and the second structural beam 102 away from the front bulkhead assembly 401 and the cab frame 402 can maintain higher stability.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment, a transition plate 103 is provided between the first structural beam 101 and the second structural beam 102 for fixed connection, so that the first structural beam 101 and the second structural beam 102 are arranged in a stable structural whole in the front engine compartment, thereby improving the overall integrity and reducing relative swaying and shaking.

[0039] like Figure 2 , Figure 6As shown, in an optional embodiment, the two sets of wheel arch assemblies 100 are provided with mounting positions 104 for mounting and fixing the first crossbeam 201 and the second crossbeam 202. The mounting positions 104 are provided with two upright plates 105 arranged along the width direction of the vehicle body, and the two upright plates 105 are respectively fixedly connected to the transition plate 103, the first structural beam 101, and the first structural beam 101 to enclose and form a closed space.

[0040] The mounting positions 104 on the two sets of wheel arch assemblies 100 provide mounting bases for the first crossbeam 201 and the second crossbeam 202, facilitating installation. The upright plates 105 on the wheel arch assembly 100 are also fixedly connected to the first crossbeam 201 and the second crossbeam 202 respectively, and enclosed with the transition plate 103 to form a closed space, forming a stable, reliable, and strong support mounting position 104. This provides a stable mounting base for the first crossbeam 201 and the second crossbeam 202, preventing deformation at the connection between the first crossbeam 201 and the second crossbeam 202 and the wheel arch assembly 100, improving structural strength, and correspondingly further maintaining the relative stability between the first structural beam 101 and the second structural beam 102.

[0041] like Figure 3 , Figure 4 and Figure 6 As shown, in an optional embodiment, the mounting position 104 is provided with two sets of mounting points 106. The first crossbeam 201 and the second crossbeam 202 are respectively fixed to the two sets of mounting points 106 by fasteners 107. The fasteners 107 are detachably engaged on the mounting points 106 to complete the installation and removal of the first crossbeam 201 and the second crossbeam 202 from the wheel cover assembly 100.

[0042] Corresponding mounting points 106 are also provided on the first crossbeam 201 and the second crossbeam 202, and the mounting points 106 on the mounting position 104 are set accordingly to facilitate the through connection of the fasteners 107.

[0043] like Figure 6 As shown, in an optional embodiment, on each set of wheel cover assemblies 100, the distance between the two sets of mounting points 106 is less than the distance between the two upright plates 105, so as to keep the mounting points 106 arranged on the mounting position 104 and keep the mounting points 106 located in the closed space constrained by the two upright plates 105, thereby improving assembly stability.

[0044] like Figure 4 , Figure 5As shown, in an optional embodiment, the first crossbeam 201 and / or the second crossbeam 202 are provided with an L-shaped mounting bracket 204, and the first crossbeam 201 and / or the second crossbeam 202 are provided with a reinforcing section 205 with a thickness greater than that at the end.

[0045] An L-shaped mounting bracket 204 is provided on the first crossbeam 201 or the second crossbeam 202, or an L-shaped mounting bracket 204 is provided on both the first crossbeam 201 and the second crossbeam 202. The mounting bracket 204 provides a mounting base, which facilitates the installation and fixing of other components in the front engine compartment, thereby improving the convenience of layout and the overall structural reliability.

[0046] The first crossbeam 201 or the second crossbeam 202 is provided with a reinforcing section 205 with a thickness greater than that at the end in the middle, or the first crossbeam 201 and the second crossbeam 202 are provided with a reinforcing section 205 with a thickness greater than that at the end in the middle, to improve the structural strength of the first crossbeam 201 and the second crossbeam 202 and maintain the overall torsional and bending resistance after other components are fixed on the mounting bracket 204.

[0047] like Figure 2 , Figure 7 As shown, in an optional embodiment, the hinge mounting component 203 includes a first reinforcing part 301 and a second reinforcing part 302 fixedly connected along the vehicle height direction. The first reinforcing part 301 and the second reinforcing part 302 each include a connecting section 303 fixedly connected to the first structural beam 101, a mounting section 304 perpendicular to the first structural beam 101, and a support section 305 fixedly disposed between the connecting section 303 and the mounting section 304. The mounting surface is disposed on the mounting section 304. The first reinforcing part 301 and the second reinforcing part 302 are fixedly connected relative to each other, wherein the mounting section 304 on the first reinforcing part 301 and the mounting section 304 on the second reinforcing part 302 are abutted and fixedly connected. Then, the connecting section 303 on the first reinforcing part 301 and the connecting section 303 on the second reinforcing part 302 are fixedly connected to the first structural beam 101. The support section 305 also supports the mounting section 304 and the connecting section 303, maintaining the structural stability of the mounting section 304 and improving work efficiency.
