Description

[0002] An extended-range electric vehicle is a hybrid vehicle. When the battery pack of the vehicle is low on power, the generator in the range extender inside the vehicle generates electricity and supplies power to the battery pack or the drive motor.

DETAILED DESCRIPTION

[0060] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0061] First, the terms involved in this application are explained:

[0062] Suspension: refers to the vehicle powertrain component used to reduce and control the transmission of engine vibration and play a supporting role.

[0063] As shown in the background technology, in the prior art, the range extender and the drive motor are integrated in the engine compartment of the vehicle to save the space occupied by the range extender and the drive motor. However, this arrangement of the range extender and the drive motor only allows the use of drive motors with smaller size and lower power, which affects the acceleration and maximum climbing grade of the vehicle.

[0064] In response to the above technical problems, the embodiment of the present application provides a cabin structure and a vehicle, wherein the cabin structure includes a frame, a range-extending mechanism and a drive motor, the frame includes two longitudinal beams and at least two cross beams, the range-extending mechanism and the drive motor are independently arranged, the range-extending mechanism is fixed by connecting to the two longitudinal beams of the frame, the drive motor is fixed by connecting to the two longitudinal beams and one cross beam, and there is no connection structure between the range-extending mechanism and the drive motor, thereby avoiding the limitation of the range-extending mechanism on the installation space of the drive motor, which is conducive to the arrangement of a higher-power drive motor in the cabin. In addition, arranging the range-extending mechanism above the drive motor can free up the space in the cabin along the longitudinal beam direction, provide a larger installation space for the drive motor, and arrange a high-power drive motor with better dynamic performance, which is conducive to improving the acceleration and maximum climbing grade of the vehicle.

[0065] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0066] It should be noted that the cabin structure provided in the embodiment of the present application can be applied to a variety of different vehicles.

[0067] See also Figure 1 , Figure 2 and Figure 6As shown, the cabin structure of the embodiment of the present application includes a frame 100, a range-extending mechanism 200 and a drive motor 300; the frame 100 includes two longitudinal beams 110 and at least two transverse beams; the range-extending mechanism 200 is electrically connected to the drive motor 300 for supplying power to the drive motor 300; the drive motor 300 is arranged above two adjacent transverse beams, and the range-extending mechanism 200 is arranged above the drive motor 300; the drive motor 300 is connected to two longitudinal beams 110 and one transverse beam, and the range-extending mechanism 200 is connected to the two longitudinal beams 110.

[0068] In a specific implementation, the greater the maximum power of the driving motor 300 is, the larger the volume of the corresponding driving motor 300 is. Therefore, in order to install a driving motor 300 with a higher power, a larger installation space must be provided for the driving motor 300.

[0069] In the present application, the range extender mechanism 200 and the drive motor 300 are independently arranged in the engine compartment of the vehicle, so there are separate connection points between the range extender mechanism 200 and the drive motor 300 and the frame 100. Specifically, the drive motor 300 is connected to two longitudinal beams 110 and a cross beam, and the range extender mechanism 200 is connected to the two longitudinal beams 110, thereby fixing the drive motor 300 and the range extender mechanism 200 on the frame 100 respectively. This can reduce the restrictions of the range extender mechanism 200 on the installation space of the drive motor 300, so that a drive motor 300 with a larger volume and a larger maximum power can be selected.

[0070] In addition, the range extending mechanism 200 is arranged above the driving motor 300 so that the range extending mechanism 200 and the driving motor 300 are Figure 2 Compared with setting the two in parallel, the overall distance between the range extender mechanism 200 and the drive motor 300 can be effectively reduced. Figure 2 The space occupied in the X direction as shown is reduced, thereby freeing up more space in the X direction in the cabin, which is conducive to setting up a larger drive motor 300 to increase the maximum power and dynamics of the drive motor 300 in the vehicle, thereby improving the acceleration and maximum climbing grade of the vehicle.

[0071] In some possible implementations, see Figure 1 , Figure 5 and Figure 6 As shown, at least two beams of the embodiment of the present application include a first beam 120, a second beam 130 and a third beam 140; the first beam 120, the second beam 130 and the third beam 140 are arranged in sequence from the head of the vehicle along the length direction of the vehicle; the drive motor 300 is arranged above the second beam 130 and the third beam 140; the range extender mechanism 200 is arranged above the second beam 130.

[0072] In a specific implementation, the drive motor 300 is arranged above the second cross beam 130 and the third cross beam 140. In this way, when the vehicle is hit head-on, the main deformation of the frame occurs in the front and rear positions of the first cross beam 120, avoiding the drive motor 300 from being directly impacted and causing serious damage.

[0073] In addition, the range extender mechanism 200 is arranged above the second cross beam 130, so that the range extender mechanism 200 is located in the front and upper part of the drive motor 300. The range extender mechanism 200 overlaps with a corner of the drive motor 300 in the Z direction, which can avoid the range extender mechanism 200 from excessively restricting the volume of the drive motor 300 and can achieve the effect of saving space in the X direction.

[0074] In some possible implementations, see Figure 1 , Figure 5 and Figure 6 As shown, the embodiment of the present application includes at least four first suspensions 400, and the first suspensions 400 are used to connect to the range extender mechanism 200; each first suspension 400 is symmetrically arranged on the inner side of the two longitudinal beams 110; one end of the two first suspensions 400 close to the head of the vehicle is connected to the first cross beam 120, and the other end thereof is connected to the second cross beam 130.

[0075] It is understandable that at least four first suspensions 400 are symmetrically arranged on the inner side of the two longitudinal beams 110 of the frame 100, which can filter the vibration of the engine in the range-extending mechanism 200, wherein the four first suspensions 400 are respectively connected to the four corners of the range-extending mechanism 200, and the diagonal arrangement of the first suspensions 400 helps to improve the stability of the fixation of the range-extending mechanism 200. In addition to the four first suspensions 400 arranged at the four corners of the range-extending mechanism 200, other first suspensions 400 can be arranged on the longitudinal beam 110 to support the range-extending mechanism according to factors such as the shape and weight of the range-extending mechanism 200. The specific number of the first suspensions 400 is not limited in this application, and it is sufficient to be able to fix the range-extending mechanism 200 on the frame 100.

[0076] It should be noted that, in order to further improve the load-bearing capacity of the first suspension 400 and the stability of the range-extending mechanism 200, the two first suspensions 400 near the head of the vehicle are arranged between the first crossbeam 120 and the second crossbeam 130, and the two ends of the first suspension 400 are respectively connected to the first crossbeam 120 and the second crossbeam 130, so that the pressure of the range-extending mechanism 200 is transmitted to the first crossbeam 120 and the second crossbeam 130. In addition, the two first suspensions 400 near the head of the vehicle are also connected to the longitudinal beam 110 to limit the position of the first suspension 400 and further improve the stability of the first suspension 400.

[0077] In some possible implementations, see Figure 1 , Figure 5 and Figure 6As shown, the embodiment of the present application includes at least three second suspensions 500, and the second suspensions 500 are used to connect to the drive motor 300; at least one base 131 is arranged on the second cross beam 130, and at least one second suspension 500 is correspondingly connected to the base 131; at least two second suspensions 500 are symmetrically arranged on the two longitudinal beams 110, and the second suspensions 500 on the longitudinal beams 110 are arranged near the connection between the third cross beam 140 and the longitudinal beam 110.

[0078] It should be noted that the projection of the drive motor 300 in the XY plane is triangular, and at least three second suspensions 500 are provided, wherein the three second suspensions 500 correspond to the three corners of the drive motor 300, two second suspensions 500 are provided near the connection between the third cross beam 140 and the longitudinal beam 110, and one second suspension 500 is provided on the base 131 of the second cross beam 130, and the three second suspensions 500 form a triangular stable structure, thereby improving the stability of the drive motor 300. In addition to the second suspensions 500 provided corresponding to the three corners, other second suspensions 500 may be provided according to the shape of the drive motor 300 and its positional relationship with the frame 100 to further enhance the stability, and the specific number and position of the other second suspensions 500 are not limited in this application, and the stability of the connection between the drive motor 300 and the frame 100 can be maintained.

[0079] In some possible implementations, see Figure 1 and Figure 6 As shown, the vehicle frame 100 of the embodiment of the present application further includes two energy absorbing beams 150 ; one end of the energy absorbing beam 150 is connected to the first cross beam 120 , and the other end of the energy absorbing beam 150 is connected to the second cross beam 130 .

[0080] In specific implementation, since the range extender mechanism 200 and the drive motor 300 are independently arranged, and in order to set a higher-power drive motor 300, a larger-volume drive motor 300 is arranged in the engine compartment, the space in the engine compartment becomes more compact. To ensure the safety of the vehicle, it is necessary to ensure the anti-collision performance of the frame 100. Two energy-absorbing beams 150 are arranged between the first crossbeam 120 and the second crossbeam 130. When the front of the vehicle is hit, the energy-absorbing beam 150 collapses to absorb energy, avoiding transmitting excessive force to the second crossbeam 130 to damage the range extender mechanism 200 and the drive motor 300.

[0081] In some possible implementations, see Figure 1 and Figure 6 As shown, the vehicle frame 100 of the embodiment of the present application further includes two crushed portions 160 ; the two crushed portions 160 are respectively connected to one end of the two longitudinal beams 110 close to the head of the vehicle, and both ends of the first cross beam 120 are respectively connected to the two crushed portions 160 .

[0082] Specifically, the head of the vehicle frame 100 is an anti-collision beam 170, and the crush portion 160 is arranged between the longitudinal beam 110 and the anti-collision beam 170. When the vehicle is hit, the anti-collision beam 170 is first impacted and the force is transferred to the crush portion 160. After the crush portion 160 collapses and absorbs part of the energy, the remaining energy is transferred to the energy-absorbing beam 150 at the rear of the first cross beam 120 to absorb energy again, thereby further preventing the range extender mechanism 200 and the drive motor 300 from being damaged.

[0083] In some possible implementations, see Figure 5 and Figure 6 As shown, in the embodiment of the present application, breaking points (not shown in the figure) are set on the two first suspensions 400 close to the energy absorbing beam 150; the breaking points are configured so that when the vehicle collides, the first suspension 400 is disconnected at the breaking points.

[0084] In some embodiments, since the first suspension 400 is disposed on the inner side of the longitudinal beam 110 and the two first suspensions 400 parts close to the energy absorbing beam 150 are located above the energy absorbing beam 150, the force transmission path of the energy absorbing beam 150 may be affected. Therefore, breaking points are set on the two first suspensions 400 close to the energy absorbing beam 150. When the vehicle is hit, the first suspension 400 can be quickly disconnected at the breaking points, thereby ensuring the effective force transmission path of the energy absorbing beam 150 and improving the energy absorption effect of the energy absorbing beam 150, thereby improving the safety of the vehicle.

[0085] In some possible implementations, see Figure 1 , Figure 3 and Figure 4 As shown, the range extender mechanism 200 of the embodiment of the present application includes a power generation component 210 and an engine 220; the power generation component 210 is connected to the engine 220, and the power generation component 210 and the engine 220 are arranged in sequence along the width direction of the vehicle, and the power generation component 210 and the engine 220 are respectively connected to each first suspension 400 symmetrically arranged on the inner side of the two longitudinal beams 110.

[0086] In a specific implementation, the range-extending mechanism 200 includes a power generation assembly 210 and an engine 220, which are arranged in parallel along the Y direction, so the power generation assembly 210 and the engine 220 are respectively connected to the first suspension 400 on the inner side of the two longitudinal beams 110. When the battery pack in the vehicle is insufficient, the engine 220 can burn fuel to start the power generation assembly 210 to generate electricity, and provide electricity to the battery pack or the drive motor 300 to ensure the vehicle's mileage.

[0087] In some possible implementations, see Figure 2 and Figure 4As shown, the power generation component 210 of the embodiment of the present application includes a generator 211, a reducer 212 and a controller 213; the first suspension 400 is connected to the reducer 212, the reducer 212 is connected to the generator 211, the generator 211 and the drive motor 300 are both electrically connected to the controller 213, and the controller 213 is used to control the generator 211 and the drive motor 300.

[0088] Specifically, the generator 211, the reducer 212 and the controller 213 are integrated, and the reducer 212 is arranged at the lower part of the generator 211. Therefore, the generator assembly 210 can be fixed on the frame 100 by connecting the reducer 212 to the first suspension 400. Only one controller 213 can simultaneously control the two components of the generator 211 and the drive motor 300, which effectively saves the space occupied by the controller 213 in the cabin and provides more installation space for the drive motor 300.

[0089] See also Figure 1 As shown, an embodiment of the present application also provides a vehicle, comprising a vehicle body and any of the above-mentioned cabin structures arranged on the vehicle body.

[0090] Among them, the specific structure and working principle of the cabin structure are described in detail in the above embodiments, and will not be repeated here.

[0091] In the present application, the above-mentioned cabin structure is set on the vehicle body, and the range extender mechanism 200 and the drive motor 300 are reasonably arranged without affecting the anti-collision performance of the vehicle. A larger installation space can be provided for the drive motor 300 in the cabin, so that a larger and more powerful drive motor 300 can be set, thereby improving the acceleration and maximum climbing grade of the vehicle.

[0092] In summary, the cabin structure provided in the present application includes a frame 100, a range extender mechanism 200 and a drive motor 300. The range extender mechanism 200 and the drive motor 300 are respectively installed on the frame 100 through a first suspension 400 and a second suspension 500, and the range extender mechanism 200 is arranged in the upper front of the drive motor 300, thereby releasing a larger installation space for the drive motor 300, so that a higher-power drive motor 300 can be installed in the cabin of the vehicle, thereby enhancing the acceleration of the vehicle and improving its maximum climbing grade.
