Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and more specifically, to a robust intelligent chassis. Background Technology

[0002] The intelligent chassis is a key technology area for intelligent vehicles. It integrates advanced electronic control technology, sensor technology, and mechanical systems to achieve real-time monitoring and precise control of the vehicle's driving status. First, it receives the driver's driving intentions and the vehicle's trajectory planning information through various sensors and intelligent driving controllers. Then, the Vehicle Motion Controller (VMC) uses the vehicle's kinematic model to calculate and analyze, generating coordinated control commands. Finally, these commands are distributed to various actuators such as brakes, suspension, drive, and steering to achieve precise vehicle handling and stable driving. The main features of the intelligent chassis are hardware and mechanical decoupling, application layer and software separation, and failure-proof operation, which can provide more precise control and higher safety. It has wide applications in autonomous driving, cockpit, and powertrain systems, providing important support for the intelligent development of vehicles.

[0003] With the rapid development of intelligent technology, the stability and safety of intelligent chassis, as a core component of intelligent vehicles, are receiving increasing attention. In practical applications, intelligent chassis often face various complex environments and working conditions, especially their performance in collision situations, which directly affects the overall performance and safety of intelligent vehicles. However, traditional intelligent chassis do not adequately consider the stability and safety of collision situations. In addition, with the continuous advancement of battery technology, battery packs of different thicknesses are gradually being applied to intelligent vehicles. Traditional chassis designs are unable to adapt to this diversity, making the installation and fixing of battery packs complex and affecting the overall design and user experience of intelligent vehicles. Utility Model Content

[0004] The main objective of this invention is to provide a robust smart chassis that can effectively address the challenges posed by the rapid development of intelligent technology. As a core component of intelligent vehicles, the stability and safety of smart chassis are receiving increasing attention. In practical applications, smart chassis frequently face various complex environments and working conditions, and their performance in collision scenarios directly impacts the overall performance and safety of the intelligent vehicle. However, traditional smart chassis do not adequately consider stability and safety during collisions. Furthermore, with the continuous advancement of battery technology, battery packs of varying thicknesses are increasingly being used in intelligent vehicles. Traditional chassis designs struggle to adapt to this diversity, leading to complex battery pack installation and securing, thus affecting the overall design and user experience of the intelligent vehicle.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a robust intelligent chassis, comprising a chassis body, wherein several lidar mounting positions and two frame connection points are provided on both sides of the chassis body, a controller mounting position and a domain control computing power GPU position are provided between the two frame connection points, a battery pack position is provided between the controller mounting position and the domain control computing power GPU position, a photoelectric pulse mounting position is provided between the controller mounting position and the battery pack position, a chassis floor position is provided between the domain control computing power GPU position and the battery pack position, and several shock-absorbing mounting positions and several anti-collision support beams are provided on the chassis body.

[0006] Preferably, the battery pack is positioned on the chassis body with two support plates, each support plate having a guide groove and several threaded holes, and a guide slider is slidably disposed within the guide groove.

[0007] Preferably, a placement plate is provided between the two guide sliders, and a groove is provided on one side of the placement plate.

[0008] Preferably, several through slots are provided on both sides of the groove, and fixing bolts are provided in the through slots.

[0009] Preferably, the support plate is fixedly installed on the chassis body.

[0010] Preferably, the guide slider is fixedly connected to the placement plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) When this utility model is used, the external shock absorber can be installed at a specific position on the chassis body through the shock absorption mounting position, which can effectively absorb and buffer the vibration and impact of the chassis during driving, which helps to improve the stability of the chassis. At the same time, the anti-collision support beam can absorb and disperse the collision energy when the chassis collides, protect the internal components and personnel of the chassis, and ensure the stability and safety of the chassis in the collision situation.

[0013] (2) When the position of the placement plate needs to be adjusted according to the thickness of the battery pack, the present invention first rotates the fixing bolt and removes the fixing bolt from the threaded hole and through groove. Then, the placement plate is moved to one side and guided by the guide groove and guide slider. When the placement plate is moved to the required position, the fixing bolt is put back into the through groove and the corresponding threaded hole. The fixing bolt is rotated to fix the placement plate, thereby adjusting the position of the placement plate according to the thickness of the battery pack, which can adapt to battery packs of different thicknesses.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1 As shown, a robust smart chassis includes a chassis body 1. Several lidar mounting positions 2 and two frame connection points 3 are provided on both sides of the chassis body 1. A controller mounting position 4 and a domain-controller computing power GPU position 5 are provided between the two frame connection points 3. A battery pack position 6 is provided between the controller mounting position 4 and the domain-controller computing power GPU position 5. A photoelectric pulse mounting position 7 is provided between the controller mounting position 4 and the battery pack position 6. A chassis floor position 8 is provided between the domain-controller computing power GPU position 5 and the battery pack position 6. Several shock-absorbing mounting positions 9 and several anti-collision support beams 10 are provided on the chassis body 1.

[0019] like Figure 2 As shown, in another embodiment of the present invention, the battery pack position 6 is provided with two support plates 601 on the chassis body 1. The support plates 601 are provided with guide grooves 602 and a plurality of threaded holes 603. A guide slider 604 is slidably disposed in the guide grooves 602.

[0020] A placement plate 605 is provided between the two guide sliders 604, and a groove 606 is provided on one side of the placement plate 605;

[0021] Several through slots 607 are provided on both sides of the groove 606, and fixing bolts 608 are provided in the through slots 607;

[0022] When the position of the placement plate 605 needs to be adjusted according to the thickness of the battery pack, first rotate the fixing bolt 608 to remove it from the threaded hole 603 and the through groove 607. Then, move the placement plate 605 to one side and guide it using the guide groove 602 and the guide slider 604. After the placement plate 605 has moved to the required position, put the fixing bolt 608 back into the through groove 607 and the corresponding threaded hole 603, rotate the fixing bolt 608 to fix the placement plate 605. This allows the position of the placement plate 605 to be adjusted according to the thickness of the battery pack, which can accommodate different battery packs.

[0023] The working principle of this robust intelligent chassis:

[0024] In use, external shock absorbers can be installed at specific positions on the chassis body 1 via the shock absorber mounting position 9, effectively absorbing and buffering vibrations and impacts during driving, which helps improve chassis stability. At the same time, the anti-collision support beam 10 can absorb and disperse collision energy when the chassis collides, protecting the internal components and personnel of the chassis and ensuring the stability and safety of the chassis in the event of a collision. When it is necessary to adjust the position of the placement plate 605 according to the thickness of the battery pack, first rotate the fixing bolt 608 to remove it from the threaded hole 603 and the through groove 607. Then move the placement plate 605 to one side and guide it using the guide groove 602 and the guide slider 604. After the placement plate 605 has moved to the required position, put the fixing bolt 608 back into the through groove 607 and the corresponding threaded hole 603, rotate the fixing bolt 608 to fix the placement plate 605, and thus adjust the position of the placement plate 605 according to the thickness of the battery pack, which can accommodate battery packs of different thicknesses.
