Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy vehicle chassis, in particular to a new energy vehicle chassis integrated with an electric cabin. BACKGROUND

[0002] New energy vehicles usually use batteries as power, and the batteries are arranged on the upper side of the new energy vehicle chassis, which can also act as counterweight to improve the stability of the new energy vehicle in operation.

[0003] As disclosed in a patent document in China, patent No. CN2024112283912, on November 12, 2024, a chassis assembly of an electric commercial vehicle is disclosed, wherein the middle frame is connected between the front frame and the rear frame, the front frame is located on the front side of the middle frame, the rear frame is located on the rear side of the middle frame, the middle frame and the rear frame are at the same vertical height, the vertical height of the front frame is lower than the vertical height of the middle frame, the electric commercial vehicle includes a cab, the cab is fixedly installed on the front frame, and the power battery pack is fixedly installed on the middle frame and located below the middle frame. By setting the main frame in a stepped structure with the front lower and the rear higher, the cab is arranged on the front frame, and the power battery pack is hung at the bottom of the middle frame, which effectively reduces the vehicle's center of gravity, reduces the risk of rollover, and improves safety performance.

[0004] The existing technology has the following disadvantages: when a new energy vehicle is hit by a large impact force in an accident, the battery is connected, and due to a short circuit in the circuit, a fire is likely to occur, which is not easy to rescue compared to a traditional oil vehicle. SUMMARY

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the present application provides a new energy vehicle chassis integrated with an electric cabin, which is not easy to catch fire even when the vehicle body is deformed when the vehicle is hit by a large impact force, thereby improving rescue efficiency and safety.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions.

[0007] A The new energy vehicle chassis integrated with the electric cabin comprises a first longitudinal beam, a first transverse beam, a second longitudinal beam and a second transverse beam connected end to end, a front beam extending forward is arranged on the first transverse beam, the projection of the front beam on the first transverse beam is located between the first longitudinal beam and the second longitudinal beam, a support beam is connected between the first transverse beam and the second transverse beam, the support beam is arranged along the front beam to bear the axial load of the front beam, an electric cabin is fixedly connected to the first longitudinal beam and the second longitudinal beam and is arranged on the support beam, a plug-in board is fixedly arranged on the support beam, and the plug-in board and the electric cabin are plug-in connected together for power taking.

[0008] When a car is rear-ended or involved in a high-speed collision, it is usually subjected to an impact force from front to back. When the chassis of the new energy vehicle disclosed in this application is impacted at the front, the front beam transmits the impact force backward, and the greater force is transmitted to the support beam. During this process, the first and second crossbeams are more prone to deformation than the front beam and the support beam. When the first and second crossbeams deform backward, the support beam moves backward relative to the first and second longitudinal beams, causing the plug-in board and the electrical compartment to separate, thereby cutting off the power to the entire new energy vehicle and avoiding the problem of the new energy vehicle catching fire due to a short circuit. This improves the rescue efficiency and safety of the new energy vehicle in the event of a car accident.

[0009] Preferably, the second crossbeam has a concave, easily deformable area on the side opposite to the support beam. This slight reduction in the strength of the second crossbeam enhances its directional deformation capability, and the easily deformable area facilitates changes in the position of the support beam relative to the electrical compartment, thus improving the safety performance of the new energy vehicle.

[0010] Preferably, the front beam consists of two spaced-apart beams, with the front ends of the two beams connected to a front crossbeam. The two front beams, together with the front crossbeam, form the front structure of the new energy vehicle chassis, providing reliable load-bearing capacity and impact resistance. When the impact force is insufficient to cause chassis deformation, minor collisions will not affect the stability of the chassis structure.

[0011] Preferably, the second crossbeam has two rear beams extending rearward, which correspond axially to the first and second longitudinal beams, respectively. The rear beams form the rear structure of the new energy vehicle chassis, ensuring the chassis's load-bearing capacity.

[0012] Preferably, the electrical compartment includes a compartment body and a mounting bracket. The mounting bracket connects the first longitudinal beam and the second longitudinal beam, and the compartment body is fixedly connected to the mounting bracket. The mounting bracket is erected on a support beam. The electrical compartment is connected to the first and second longitudinal beams through the mounting bracket. The mounting bracket is erected on the support beam, and the two are not fixed, which ensures the sliding capability of the support beam relative to the electrical compartment.

[0013] Preferably, the mounting bracket is equipped with guide grooves that cooperate with the support beam to guide the relative sliding of the mounting bracket and the support beam. By using the guide grooves in conjunction with the support beam, the sliding path of the electrical compartment and the support beam is constrained, ensuring reliable separation of the power board and the electrical compartment when the chassis is impacted and moved backward, thereby breaking the circuit and ensuring rescue efficiency.

[0014] Preferably, the power strip is vertically connected to the support beam, and a support corner plate is provided on the rear side of the power strip to connect to the support beam. When the electrical compartment is installed in place, it is close to or abuts against the power strip. A mating electrical plug is provided between the power strip and the electrical compartment. In this configuration of the power strip, the support corner plate ensures the structural strength of the power strip, and the electrical plug enables reliable electrical connection between the power strip and the electrical compartment, ensuring reliable power strip functionality.

[0015] Preferably, the support beam includes a first beam and a second beam arranged in parallel at intervals. The first beam and the second beam work together to improve the support strength of the chassis bottom, while also ensuring reliable mounting of the power strip.

[0016] Preferably, the front end of the mounting bracket and the first crossbeam are spaced apart axially along the support beam to provide deformation space for the first crossbeam. The deformation space of the first crossbeam provides room for deformation of the first crossbeam upon impact, and after the first crossbeam deforms, it can act on the deformation of the support beam, thereby realizing the retraction and power-off of the plug-in.

[0017] Preferably, the mounting bracket includes connecting rods and a connecting tray. Several connecting rods are provided on both sides of the connecting tray, and these connecting rods are fixedly connected to the first longitudinal beam and the second longitudinal beam, respectively. The connecting tray and the connecting rods are also fixedly connected. The connecting rods, together with the support beams, form an elevated structure with independent first crossbeams, first longitudinal beams, second crossbeams, and second longitudinal beams. This structure is less likely to affect the stability of the electrical compartment structure when the vehicle body is subjected to a lateral impact, further improving the safety of new energy vehicles.

[0018] After adopting the above solution, when the new energy vehicle used in this invention is subjected to a large impact, the entire new energy vehicle loses power, avoiding the problem of fire caused by short circuits, and improving the rescue efficiency and safety of the new energy vehicle in the event of a car accident.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0026] The terms “comprising” and “having”, and any variations thereof, used in the specification and claims of this invention are intended to cover a non-exclusive inclusion, such as a method or product that includes a series of technical features, not necessarily limited to those technical features explicitly listed, but may also include other technical features that may be included in the method or product but not explicitly listed.

[0027] In the description of this invention, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only used to clearly describe the defined technical features and to clearly distinguish the defined technical features from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this invention.

[0028] Example 1, A new energy vehicle chassis with an integrated electric compartment, such as Figures 1 to 4 As shown, the structure includes a first longitudinal beam 1, a first transverse beam 2, a second longitudinal beam 3, and a second transverse beam 4 connected end-to-end. The area enclosed by these beams is used for the overhead installation of the electrical compartment 11. A front beam 5 extending forward is provided on the first transverse beam 2. The front beam 5 has two spaced-apart sections, and the front ends of the two front beams 5 are connected to a front transverse beam 6. The projection of the front beam 5 onto the first transverse beam 2 lies between the first longitudinal beam 1 and the second longitudinal beam 3. Two rear beams 7 extending backward are provided on the second transverse beam 4, and the two rear beams 7 are axially aligned with the first longitudinal beam 1 and the second longitudinal beam 3, respectively.

[0029] A support beam 8 connects the first crossbeam 2 and the second crossbeam 4. The support beam 8 includes a first branch beam 9 and a second branch beam 10 arranged in parallel at intervals. The support beam 8 is arranged along the front beam 5 to bear the axial load of the front beam 5. The electrical compartment 11 is fixedly connected to the first longitudinal beam 1 and the second longitudinal beam 3 and is mounted on the support beam 8. The electrical compartment 11 includes a compartment body 12 and a mounting bracket 13. The mounting bracket 13 connects the first longitudinal beam 1 and the second longitudinal beam 3. The compartment body 12 is fixedly connected to the mounting bracket 13, which is mounted on the support beam 8. The mounting bracket 13 is provided with a guide groove that matches the support beam 8 to guide the relative sliding of the mounting bracket 13 and the support beam 8. The front end of the mounting bracket 13 and the first crossbeam 2 are spaced apart axially along the support beam 8 to provide deformation space for the first crossbeam 2. The mounting bracket 13 includes connecting rods 14 and connecting trays 15. Several connecting rods 14 are respectively provided on both sides of the connecting tray 15. Several connecting rods 14 are fixedly connected to the first longitudinal beam 1 and the second longitudinal beam 3. The connecting tray 15 and the connecting rods 14 are fixedly connected. (Details follow...) Figure 1 and Figure 2 As shown, two connecting rods 14 are provided on each side of the connecting tray 15. The two connecting rods 14 on the same side of the connecting tray 15 are spaced apart. The connecting rods 14 are fixed to the side of the first longitudinal beam 1 or the second longitudinal beam 3 by bolts 18. The side of the connecting tray 15 is provided with a connecting edge 16, and the connecting edge 16 is provided with multiple "U"-shaped connecting grooves 17. After the connecting edge 16 is mounted on the connecting rod 14, it is locked by the connecting grooves 17 and the upper side bolts 18 at the end of the connecting rod 14. There is a gap between the end of the connecting rod 14 and the side of the connecting tray 15, so that although the connecting tray 15 is mounted and fixed on the connecting rod 14, it is not completely locked and fixed to the connecting rod 14. When the first longitudinal beam 1 and the second longitudinal beam 3 deform, that is, when the side of the new energy vehicle is impacted, the deformation of the first longitudinal beam 1 and the second longitudinal beam 3 is first absorbed by the gap between the connecting rod 14 and the connecting tray 15, and will not directly affect the battery, thereby improving the safety of the new energy vehicle in side collisions.

[0030] A power strip 19 is fixed on the support beam 8, and the power strip 19 is vertically connected to the support beam 8. A support angle plate 20 connecting the power strip 19 to the support beam 8 is provided on its rear side. When the electrical compartment 11 is installed, it is close to or abuts against the power strip 19. A mating electrical plug 21 is provided between the power strip 19 and the electrical compartment 11. The power strip 19 and the electrical compartment 11 are plugged in to draw power. The support beam 8 has wiring holes or wiring channels, and the wires connected to the power strip 19 are arranged through the wiring channels.

[0031] When the chassis of the new energy vehicle disclosed in this application is impacted at the front, the front beam 5 transmits the impact force to the rear, and the greater force is transmitted to the support beam 8. During this process, the first crossbeam 2 and the second crossbeam 4 are more prone to deformation under lateral stress than the front beam 5 and the support beam 8 under axial stress. When the first crossbeam 2 and the second crossbeam 4 deform to the rear, the support beam 8 moves rearward relative to the first longitudinal beam 1 and the second longitudinal beam 3, causing the plug-in board 19 and the electrical compartment 11 to separate, thereby cutting off the power to the entire new energy vehicle and avoiding the problem of fire caused by short circuit in the new energy vehicle, thus improving the rescue efficiency and safety of the new energy vehicle in the event of a car accident.

[0032] Example 2, The integrated electric compartment 11 is a new energy vehicle chassis, such as Figure 5 As shown, the only difference between Embodiment 2 and Embodiment 1 is that the second crossbeam 4 has a concave deformable area 22 on the side opposite to the support beam 8. The deformable area 22 is a concave arc groove. By setting the deformable area 22, the strength of the second crossbeam 4 is weakened to a certain extent, thereby enhancing the directional deformation capability of the second crossbeam 4 relative to the support beam 8. The setting of the deformable area 22 facilitates the change of position of the support beam 8 relative to the electrical compartment 11, thereby improving the safety performance of the new energy vehicle.
