Automakers need to design and develop different models in a timely manner according to market demand.

[0003] In the related art, the skateboard chassis is a type of chassis. The skateboard chassis integrates the steering, braking, three-electric, suspension and other systems of the original car on the chassis of the car through modular design. Due to the modular design, only the corresponding modules can be changed according to the requirements of different models without changing the chassis, which can achieve the decoupling of the chassis and the body.

[0004] However, since all components are integrated and installed on the skateboard chassis, the layout space of the skateboard chassis becomes crowded, so the skateboard chassis will increase its thickness to obtain more accommodation space, which increases the height of the entire vehicle and even compresses the indoor longitudinal space of the cabin, reducing key performance of the vehicle such as wind resistance and riding space.

[0011] In another embodiment of the present disclosure, the rear power module includes a rear drive, two rear wheels and two rear suspensions. The rear drive is located between the two rear beams.

[0036] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0037] The disclosed embodiment provides a skateboard chassis structure, Figure 1 is a schematic diagram of a skateboard chassis structure provided by an embodiment of the present disclosure, such as Figure 1As shown, it includes a frame longitudinal beam 10, an integrated battery pack 20, a front power module 30 and a rear power module 40. The frame longitudinal beam 10 includes a front beam portion 101, a middle beam portion 102 and a rear beam portion 103 which are connected in sequence. There are two frame longitudinal beams 10, and the two frame longitudinal beams 10 are arranged side by side and spaced apart, and the front beam portions 101, the middle beam portions 102 and the rear beam portions 103 of the two frame longitudinal beams 10 correspond to each other, and the distance between the two front beam portions 101 and the distance between the two rear beam portions 103 are both smaller than the distance between the two middle beam portions 102. The front power module 30 is respectively connected to the two front beam portions 101, the rear power module 40 is respectively connected to the two rear beam portions 103, and the integrated battery pack 20 is respectively connected to the two middle beam portions 102.

[0038] The base of the entire skateboard chassis is formed by arranging two frame longitudinal beams 10 in parallel and at intervals. The space between the two frame longitudinal beams 10, the area between the front beams 101 accommodates the front power module 30, the area between the rear beams 103 accommodates the rear power module 40, and the area between the middle beams 102 accommodates the integrated battery pack 20. The arrangement of the front power module 30 and the rear power module 40 effectively improves the power performance of the entire vehicle. In addition, since the sizes of the front power module 30 and the rear power module 40 are usually smaller than the size of the integrated battery pack 20, the distance between the two front beams 101 and the distance between the two rear beams 103 are designed to be smaller than the distance between the two middle beams 102, which can effectively reduce the space occupied by the frame longitudinal beams 10.

[0039] That is to say, the skateboard chassis structure adopts a streamlined frame longitudinal beam 10 structure, a full integrated battery pack 20 layout, and modularization of an integrated front power module 30 and a rear power module 40, which can make the layout space of the skateboard chassis structure more compact, reduce the thickness of the skateboard chassis, and is beneficial to optimizing the key performance of the car such as wind resistance and riding space.

[0040] It is worth noting that the integrated battery pack 20 is a CTC (Cell to Chassis, battery-body integration technology) battery pack, which is a structured battery solution. The battery cells of the integrated battery pack 20 are directly integrated into the skateboard chassis, further deepening the integration of the battery system and the power system, reducing the number of components, saving space, reducing vehicle weight, and increasing battery life.

[0041] In this embodiment, see Figure 1The frame longitudinal beam 10 further includes a front connecting portion 104 and a rear connecting portion 105. The front connecting portion 104 is respectively inclined to the front beam portion 101 and the middle beam portion 102, one end of the front connecting portion 104 is connected to the front beam portion 101, and the other end of the front connecting portion 104 is connected to one end of the middle beam portion 102. The rear connecting portion 105 is respectively inclined to the middle beam portion 102 and the rear beam portion 103, one end of the rear connecting portion 105 is connected to the other end of the middle beam portion 102, and the other end of the rear connecting portion 105 is connected to the rear beam portion 103.

[0042] For example, because the front connecting portion 104 and the rear connecting portion 105 are inclined to the front beam portion 101, the middle beam portion 102 and the rear beam portion 103, the frame longitudinal beam 10 formed by them together presents a broken line shape, so that the area between the two frame longitudinal beams 10 is wide in the middle and narrow at both ends. Between the two frame longitudinal beams 10, the wider integrated battery pack 20 can be placed in the area between the two middle beams 102, and the narrower front power module 30 and rear power module 40 can be placed in the area between the two front beams 101 and the area between the two rear beams 103, respectively, so that the space layout utilization rate of the skateboard chassis is higher and the manufacturing cost can also be reduced.

[0043] In this embodiment, Figure 2 is a schematic diagram of a skateboard chassis structure provided by an embodiment of the present disclosure, see Figure 2 and Figure 1 The front beam portion 101, the middle beam portion 102, the rear beam portion 103, the front connecting portion 104 and the rear connecting portion 105 on the frame longitudinal beam 10 are not in the same plane. Such a design allows other modules and components to be arranged and fitted to the frame longitudinal beam 10 more flexibly and compactly, thereby improving the space utilization of the skateboard chassis.

[0044] Optionally, the front beam portion 101, the middle beam portion 102, the rear beam portion 103, the front connecting portion 104 and the rear connecting portion 105 on the frame longitudinal beam 10 are manufactured by an integrated die-casting process. The frame longitudinal beam 10 manufactured by the integrated die-casting process has a higher strength.

[0045] Optionally, when manufacturing the front beam portion 101, the middle beam portion 102, the rear beam portion 103, the front connecting portion 104 and the rear connecting portion 105 on the frame longitudinal beam 10, each individual component is first pressed out, and then these components are welded in sequence to form the integral frame longitudinal beam 10. The frame longitudinal beam 10 manufactured using the welding process has a lower cost.

[0046] In this embodiment, see Figure 1The integrated battery pack 20 includes a battery pack body 201 and two mounting longitudinal beams 202. The two mounting longitudinal beams 202 are respectively located on both sides of the battery pack body 201, and the length direction of the mounting longitudinal beams 202 is consistent with the length direction of the middle beam part 102, and the mounting longitudinal beams 202 are connected to the corresponding middle beam part 102.

[0047] For example, because the mounting longitudinal beams 202 are located on the straight edges on both sides of the battery pack body 201, the two mounting longitudinal beams 202 are respectively connected to the middle beam portions 102 of the two frame longitudinal beams 10, and the length directions of the two are consistent, the integrated battery pack 20 can be fitfully fixed to the area between the two middle beam portions 102 by the mounting longitudinal beams 202, so that the integrated battery pack 20 is directly connected to the two mounting longitudinal beams 202, thereby reducing the design of additional accommodation components for installing the integrated battery pack 20 and saving chassis layout space.

[0048] Optionally, the mounting longitudinal beams 202 located on both sides of the battery pack body 201 are directly welded to the two middle beam parts 102 respectively by welding.

[0049] Optionally, at least two threaded holes arranged along the length direction of the mounting longitudinal beam 202 are provided on the mounting longitudinal beam 202, and at least two threaded holes arranged along the length direction of the middle beam portion 102 are provided on the middle beam portion 102 of the frame longitudinal beam 10. The threaded holes on the mounting longitudinal beam 202 correspond to the threaded holes on the middle beam portion 102 one by one, and the two mounting longitudinal beams 202 are respectively fixed to the two middle beam portions 102 by means of threaded bolts.

[0050] In this embodiment, see Figure 1 The front power module 30 includes a front drive 301, two front wheels 302 and two front suspensions 303. The front drive 301 is located between the two front beams 101. One front wheel 302 is located on one side of the front beam 101 away from the front drive 301 and is connected to an output shaft of the front drive 301. The other front wheel 302 is located on the other side of the other front beam 101 away from the front drive 301 and is connected to another output shaft of the front drive 301. One front suspension 303 is respectively connected to one front wheel 302 and a corresponding front beam 101, and the other front suspension 303 is respectively connected to the other front wheel 302 and the corresponding other front beam 101.

[0051] Exemplarily, the front drive component 301 includes a motor and two output shafts. The motor is accommodated in the area between the two front beams 101. The two output shafts are connected to the motor at one end and to a front wheel 302 at the other end. The two front beams 101 are placed between the motor and the front wheel 302. The two front wheels 302 are respectively connected and fixed to the two front beams 101 through two front suspensions 303, so that the front power module 30 is connected and fixed to the frame longitudinal beam 10, and the generated driving torque serves as the front power source of the entire skateboard chassis.

[0052] As further explained, the output shaft is composed of a shaft tube, a telescopic sleeve and a steering knuckle. As an important component for transmitting power, the power of the motor is transmitted to the front wheel 302, so that the car generates driving force. The front wheel 302 is composed of a wheel hub, a rim and a spoke. The hub connects and fixes the output shaft and the spoke, and the spoke connects and fixes the rim and the wheel hub. The front suspension 303 is composed of an elastic element, a shock absorber and a guide mechanism. It is a connecting device and a force transmission structure between the front beam part 101 and the front wheel 302. The vertical reaction force, longitudinal reaction force and lateral reaction force of the road surface on the front wheel 302 are all transmitted to the front beam part 101 to ensure the normal driving of the car.

[0053] Optionally, the motor of the front driving component 301 is a DC motor or an AC motor.

[0054] In this embodiment, see Figure 1 The front power module 30 includes a steering mechanism 304. The steering mechanism 304 is located between the two front wheels 302, and both ends of the steering mechanism 304 are respectively connected to the two front wheels 302, and the steering mechanism 304 is respectively connected to the two front beams 101.

[0055] For example, because the steering mechanism 304 is located between and connected to the two front wheels 302, and the steering mechanism 304 is fixed to the two front beams 101, the steering mechanism 304 can control the direction of the front wheels 302, thereby achieving steering of the vehicle during driving.

[0056] It is worth noting that the steering mechanism 304 is composed of a steering control mechanism and a steering transmission structure, and is fixed to the front beam portion 101 through a subframe, which can ensure that the vehicle can steer and drive according to the driver's will.

[0057] In this embodiment, see Figure 1The rear power module 40 includes a rear drive 401, two rear wheels 402 and two rear suspensions 404. The rear drive 401 is located between the two rear beams 103. One rear wheel 402 is located on one side of the rear beam 103 away from the rear drive 401 and is connected to an output shaft of the rear drive 401. The other rear wheel 402 is located on the other side of the other rear beam 103 away from the rear drive 401 and is connected to the other output shaft of the rear drive 401. One rear suspension 404 is respectively connected to one rear wheel 402 and a corresponding rear beam 103, and the other rear suspension 404 is respectively connected to the other rear wheel 402 and the corresponding other rear beam 103.

[0058] Exemplarily, the rear drive member 401 includes a motor and two output shafts, the motor of the rear drive member 401 is located in the area between the two rear beams 103, the two ends of the motor of the rear drive member 401 are respectively connected to the two output shafts of the rear drive member 401, the ends of the two output shafts in the rear drive member 401 away from the motor are respectively connected to the two rear wheels 402, and the area between the motor of the rear drive member 401 and the rear wheels 402 accommodates the rear beam 103, and then the two rear wheels 402 are respectively connected and fixed to the two rear beams 103 through the two rear suspensions 404, so that the rear power module 40 is connected and fixed to the frame longitudinal beam 10, and the rear power module 40 generates the rear power source of the skateboard chassis.

[0059] As further explained, the output shaft composed of the shaft tube, the telescopic sleeve and the steering knuckle transmits the power generated by the motor to the rear wheel 402, and the rear wheel 402 rotates to drive the car. The rear wheel 402 is composed of a hub, a rim and a spoke, the hub connects and fixes the output shaft and the spoke, and the spoke connects and fixes the rim and the hub. The rear suspension 404 is composed of an elastic element, a shock absorber and a guide mechanism, which connects the rear beam 103 with the rear wheel 402, so that the rear wheel 402 is connected to the entire frame, and as a force-transmitting structure, it can alleviate various vibrations and impacts caused by the car and road conditions when the car is driving, so as to improve the riding comfort of the passengers and ensure the normal driving of the car.

[0060] Optionally, the motor of the rear drive member 401 is a DC motor or an AC motor.

[0061] In this embodiment, the skateboard chassis structure further includes two rear wheel covers 80. One rear wheel cover 80 is connected to one rear beam portion 103, and the other rear wheel cover 80 is connected to the other rear beam portion 103. The two rear wheel covers 80 correspond to the two rear wheels 402 one by one, and the rear wheel covers 80 are arranged outside the corresponding rear wheels 402.

[0062] For example, see Figure 1 and Figure 2Because the two rear wheel covers 80 are fixed to the two rear beam portions 103 by welding, and the rear wheel covers 80 are spaced apart from the outer ring of the rear wheel 402 , the rear wheel covers 80 can protect the rear wheel 402 .

[0063] In this embodiment, see Figure 1 The skateboard chassis structure further includes a front cooling module 50 . The front cooling module 50 is located at a side of the front power module 30 away from the integrated battery pack 20 , and the front cooling module 50 is connected to the front beam portion 101 .

[0064] It is worth noting that the function of the front-end cooling module 50 is to achieve thermal management of the automobile, thereby ensuring the normal operation and service life of the automobile.

[0065] For example, because the front-end cooling module 50 is located on the side of the front power module 30 away from the integrated battery pack 20 and is fixed to the two center beams 102 through an adapter bracket, the cooling effect on the entire skateboard chassis can be achieved by installing only one front-end cooling module 50, thereby saving the layout space of the skateboard chassis.

[0066] In this embodiment, the front cooling module 50 includes a fan 501 and a radiator 502. The fan 501 and the radiator 502 are arranged side by side, and the fan 501 is located on a side of the radiator 502 facing the front power module 30.

[0067] For example, see Figure 1 Because the fan 501 and the radiator 502 are arranged side by side and located on the side of the radiator 502 facing the front power module 30, the fan 501 can blow out the heat of the radiator 502 and at the same time provide additional air cooling to the front power module 30 located on the back of the air outlet of the fan 501.

[0068] In this embodiment, the skateboard chassis structure further includes a front cross beam 60 and a rear cross beam 70. The front cross beam 60 is located between the two front beam portions 101 and is respectively connected to the two front beam portions 101. The rear cross beam 70 is located between the two rear beam portions 103 and is respectively connected to the two rear beam portions 103.

[0069] For example, see Figure 1 The front beam 101 and the rear beam 103 of the two frame longitudinal beams 10 are connected and fixed by the front cross beam 60 and the rear cross beam 70, so that the base of the entire skateboard chassis becomes more stable.

[0070] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure should be included in the protection scope of the present disclosure.
