Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and more specifically, to a roof frame structure and a vehicle. Background Technology

[0002] Currently, the autonomous driving industry is in its early stages of operation and testing, and has not yet entered the mature stage of large-scale pre-installed mass production. Therefore, retrofitting existing vehicles to integrate the sensors and equipment required for advanced intelligent driving has become the main technological approach. Retrofitting solutions typically involve integrating key components such as LiDAR and cameras onto the roof to ensure comprehensive environmental awareness. Existing technologies primarily employ two methods for rooftop integration: one utilizes a structure combining large aluminum plates and supporting beams, with sensors and equipment fixed via additional brackets or directly using threaded holes in the aluminum plate; the other uses a welded steel pipe frame, where the sensor and equipment adapter structure is directly welded to the roof frame for more direct fixation.

[0003] However, the large aluminum plate with supporting crossbeams solution presents significant technical challenges. First, the increased thickness of the aluminum plate leads to a rise in overall weight. To meet stiffness requirements, additional weight-reduction measures and the addition of carbon fiber crossbeams are necessary, increasing costs and complicating and time-consuming assembly processes, hindering efficient mass production and modification. Second, while the steel pipe welding solution improves integration and stiffness to some extent, the increased overall weight and volume, along with higher costs, limits its widespread application in autonomous vehicles.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] In order to solve the technical problem that the overall rigidity and integration of the existing roof frame structure are low, which is not conducive to vehicle modification operations, this utility model provides a roof frame structure and a vehicle.

[0028] Please refer to Figures 1 to 4As shown, according to one aspect of the present invention, a roof frame structure is provided, comprising: a mounting frame 1, including a first base plate 10 and a second base plate 20; a first mounting component 30, at least a portion of the first mounting component 30 being disposed on the first base plate 10, and at least another portion of the first mounting component 30 being disposed on the second base plate 20, the first mounting component 30 being used to connect to a lidar component; and a second mounting component 40, disposed on the first base plate 10, at least a portion of the second mounting component 40 being used to connect to a camera component; wherein, at least a portion of the mounting frame 1 is a hollow structure; along a direction perpendicular to the surface of the mounting frame 1, the cross-sectional shape of the first base plate 10 is different from the cross-sectional shape of the second base plate 20, and the cross-sectional width of the first base plate 10 is greater than the cross-sectional width of the second base plate 20.

[0029] The technical solution of this embodiment utilizes a hollow structure design for the mounting frame 1, which significantly reduces its overall weight while maintaining sufficient rigidity and strength. This facilitates vehicle modification work and ensures the stability of the roof-mounted equipment under high-speed driving and harsh road conditions. The special layout of the first mounting component 30—with one part on the first substrate 10 and the other on the second substrate 20—allows for flexible installation of the LiDAR component on the roof frame, optimizing space utilization and enhancing the versatility of the mounting frame 1. It can adjust the sensor position according to the characteristics of different vehicle models, thereby ensuring optimal detection range and viewing angle, and improving the perception capability of the autonomous driving system. The second mounting component 40 is directly mounted on the first substrate 10, with a specially designed portion for connection to the camera component. This simplifies the equipment installation process and ensures precise positioning of the camera component. Since the camera component is crucial for the accuracy of environmental perception, this design helps avoid field-of-view obstruction or angular deviation caused by installation errors, thus ensuring the safe operation of the autonomous vehicle.

[0030] Furthermore, by employing the different cross-sectional shapes of the first substrate 10 and the second substrate 20, and the design feature that the cross-sectional width of the first substrate 10 is greater than that of the second substrate 20, different cross-sectional shapes can provide customized support strength for different areas of the roof. A larger cross-sectional width means stronger load-bearing capacity and more stable connection performance, directly improving the overall performance of the roof frame and making it more adaptable to various complex working conditions. It is evident that the mounting frame 1 of this application improves the product's integration, facilitating mass production for retrofits, and thus solving the technical problem of low overall rigidity and integration in existing roof frame structures, which hinders vehicle modification operations.

[0031] In this embodiment, the roof frame structure further includes: a third mounting component 50 disposed on the first base plate 10, at least a portion of the third mounting component 50 being used to connect with an external fairing; and a fourth mounting component 60 disposed on the second base plate 20, at least a portion of the fourth mounting component 60 being used to fix external cleaning pipelines.

[0032] In the aforementioned configuration, the third mounting component 50 is used to connect with the external fairing, allowing the fairing to be securely mounted on the first base plate 10, thereby improving the vehicle's aerodynamic performance, reducing wind resistance, and increasing energy efficiency. Furthermore, the addition of the external fairing enhances the aesthetics of the roof-mounted equipment integration area, making it more in line with the streamlined trends of modern automotive design and facilitating the integration of autonomous vehicles into everyday traffic environments. The fourth mounting component 60 is mounted on the second base plate 20 to securely integrate the external cleaning pipeline onto the mounting frame 1, ensuring it is unaffected by external environmental factors. Moreover, securing the cleaning pipeline facilitates maintenance and replacement, reducing maintenance time and costs, and improving the reliability and lifespan of the autonomous driving system.

[0033] In this embodiment, at least one of the first mounting component 30, the second mounting component 40, the third mounting component 50, and the fourth mounting component 60 is detachably mounted on the mounting frame 1. This detachable mounting component design allows for quick installation and removal of the LiDAR component, camera component, external fairing, and cleaning pipeline without the need for permanent fixation. This not only simplifies the modification process but also facilitates equipment upgrades and replacements. Especially in the rapidly evolving field of autonomous driving, it allows for more flexible integration with new sensors and equipment, reducing the need to replace the entire roof frame due to equipment updates. Furthermore, it significantly improves equipment maintenance efficiency; when a component malfunctions or requires cleaning, it can be disassembled and repaired individually without affecting the normal operation of other equipment.

[0034] In this embodiment, rivet nuts 2 are respectively provided on the first substrate 10 and the second substrate 20. The first mounting component 30, the third mounting component 50, and the fourth mounting component 60 are respectively detachably connected to the first substrate 10 and / or the second substrate 20 via the rivet nuts 2. Using rivet nuts 2 to fix the mounting components ensures the stability of the connection. At the same time, due to the standardization and mass production of rivet nuts 2, maintenance costs are reduced, making replacement and repair work more economical and efficient.

[0035] like Figure 1As shown, a connector 3 is respectively provided on the first substrate 10 and the second substrate 20. The first mounting assembly 30 includes: a first connecting rod 31, one end of which is detachably connected to the connector 3 on the first substrate 10, and the other end of which is provided with a first connecting hole 310; a second connecting rod 32, one end of which is detachably connected to the connector 3 on the second substrate 20, and the other end of which is provided with a second connecting hole 320. At least a portion of the lidar assembly is connected to the first connecting rod 31 and the second connecting rod 32 through the first connecting hole 310 and the second connecting hole 320, respectively. The length a of the first connecting rod 31 and the length b of the second connecting rod 32 satisfy the condition: 4a ≤ b ≤ 6a.

[0036] By adjusting the length ratio of the first link 31 to the second link 32 (4a≤b≤6a), the installation position and detection angle of the lidar component can be precisely controlled. This design allows for flexible adjustment of the height and orientation of the lidar component on the roof frame to optimize its coverage and detection accuracy, meeting the needs of different vehicle models and operating environments. The first link 31 and the second link 32 are detachably connected to the first base plate 10 and the second base plate 20 respectively via the connector 3 for the rivet nut 2. Simultaneously, the lidar component is fixed to the first link 31 and the second link 32 respectively via the first connecting hole 310 and the second connecting hole 320. This multi-point support structure ensures the stable installation of the lidar component on the roof, maintaining equipment stability even at high speeds or in harsh road conditions, reducing vibration and displacement, and improving the reliability and data accuracy of the autonomous driving system.

[0037] Furthermore, the length ratio of the first link 31 to the second link 32 helps optimize the spatial layout on the roof frame, ensuring that the LiDAR components achieve the best installation position without affecting the integration of other equipment. At the same time, this layout also helps to rationally distribute the weight of the roof, avoiding localized overload and maintaining the vehicle's balance and stability.

[0038] In this embodiment, there are multiple first mounting components 30, and the multiple first mounting components 30 are respectively disposed on the mounting frame 1.

[0039] Specifically, the first substrate 10 includes a first plate segment 11 and a second plate segment 12. The second plate segment 12 is connected to the second substrate 20 and is disposed on the same plane. The second mounting assembly 40 includes: a mounting groove 41 disposed on the first plate segment 11, the groove shape of which is adapted to at least part of the shape of the camera assembly; mounting holes 42 and mounting protrusions 43, which are respectively disposed at intervals on the bottom wall of the mounting groove 41. At least part of the camera assembly is detachably connected to the first substrate 10 through the mounting holes 42 and the mounting protrusions 43; wherein, there is a preset included angle c between the first plate segment 11 and the second plate segment 12, and the preset included angle c satisfies: 2.5°≤c≤3.5°.

[0040] Thus, the preset included angle design (2.5°≤c≤3.5°) between the first plate segment 11 and the second plate segment 12 allows the camera component to be installed at the optimal angle, thereby optimizing its field of view coverage. This angle selection aims to balance the clear view directly in front of the vehicle with the monitoring needs of the side and above environments, ensuring that the autonomous vehicle can fully perceive its surroundings and improve driving safety. The groove shape of the mounting slot 41 matches the shape of the base part of the camera component, ensuring precise installation of the camera component and effectively avoiding shaking and displacement during installation. The combination of mounting holes 42 and mounting protrusions 43 provides a multi-point fixing method, further enhancing the stability of the camera component, and also facilitating fine-tuning of the device's position or angle later to cope with different road conditions and lighting conditions.

[0041] By employing a specific angle design and a segmented base plate structure, not only is the space on the vehicle roof fully utilized, but the angles and segmentation also optimize the strength and stability of the structure, reducing the risk of deformation caused by the equipment's own weight. This design ensures equipment installation requirements while also considering the overall structural safety and aesthetics of the roof frame.

[0042] In this embodiment, a second mounting component 40 is provided on each of the two ends of the first substrate 10 for connection with the camera component.

[0043] Specifically, the first substrate 10 includes a first plate segment 11 and a second plate segment 12. The second plate segment 12 is connected to the second substrate 20 and is disposed on the same plane. Connectors 3 are respectively disposed on the first plate segment 11 and the second plate segment 12. The third mounting assembly 50 includes: a first connecting plate 51, which is detachably connected to the connector 3 located on the first plate segment 11. The first connecting plate 51 is disposed perpendicular to the first plate segment 11. A third connecting hole 510 is disposed on the first connecting plate 51, and at least a portion of the external shroud is connected to the first substrate 10 through the third connecting hole 510; a second connecting plate 51... The connecting plate 52 is detachably connected to the connector 3 located on the second plate segment 12. The second connecting plate 52 has first positioning holes 520 on both sides. The outer fairing has a first snap-fit ​​component, which engages with the two first positioning holes 520 respectively. The second connecting plate 52 has a fourth connecting hole 521 on the end away from the second plate segment 12, for the first substrate 10 to be connected to the support substrate through the fourth connecting hole 521. The first plate segment 11 and the second plate segment 12 have a preset included angle c, which satisfies: 2.5°≤c≤3.5°.

[0044] In this way, the first connecting plate 51 is vertically connected to the first plate segment 11, and the external fairing is installed through the third connecting hole 510. This vertical layout provides good support, ensuring that the fairing is firmly attached to the roof and maintains its integrity even under complex road conditions, effectively protecting the roof-mounted equipment from damage by the external environment. The second connecting plate 52 is connected to the second plate segment 12 and has a first positioning hole 520 and a fourth connecting hole 521. This design not only optimizes the installation position of the external fairing, but also simplifies the installation process of the fairing through the cooperation of the first snap-fit ​​component and the first positioning hole 520, improving space utilization efficiency. At the same time, the presence of the fourth connecting hole 521 facilitates the connection between the first base plate 10 and the supporting base plate, enhancing the structural stability of the entire roof frame.

[0045] Furthermore, by using a pre-set angle c (2.5°≤c≤3.5°) combined with the first connecting plate 51 and the second connecting plate 52, the roof frame structure can adapt to a wider variety of vehicle models and application scenarios, improving the structure's adaptability and versatility. This means that the same roof frame solution can be applied to vehicles with different usage requirements, eliminating the need to customize a dedicated installation structure for each vehicle model, thus reducing the difficulty and cost of large-scale deployment.

[0046] The detachable connection achieved through connector 3 greatly simplifies the connection to both the external fairing and other supporting structures, significantly simplifying future maintenance and upgrades. In the field of autonomous driving, equipment updates and iterations are extremely rapid, and the detachable design ensures that the roof frame can quickly adapt to new technical requirements without requiring complete replacement or reconstruction.

[0047] In this embodiment, there are two second connecting plates 52, which are disposed at intervals in the second plate segment 12.

[0048] Specifically, the second substrate 20 is provided with a connector 3, and the fourth mounting assembly 60 includes a mounting post 61. One end of the mounting post 61 is detachably connected to the connector 3 on the second substrate 20. The mounting post 61 is provided with two second positioning holes 610 along its circumferential direction. At least a portion of the wall of the external cleaning pipeline is provided with a second snap-fit ​​member, which engages with the two second positioning holes 610 respectively. The other end of the mounting post 61 is provided with a clearance hole 611 to avoid other components on the external cleaning pipeline.

[0049] In the aforementioned configuration, the mounting post 61 is detachably connected to the connector 3 on the second base plate 20. It engages with the second snap-fit ​​component on the outer periphery of the external cleaning pipeline via the second positioning hole 610, ensuring the cleaning pipeline is securely fixed to the roof frame. This structure prevents the cleaning pipeline from shaking during vehicle operation, ensuring the normal operation of the cleaning system. Furthermore, the clearance hole 611 on the mounting post 61 provides clearance space for other components on the cleaning pipeline, preventing interference between pipelines. This feature allows the cleaning pipeline to be freely arranged in multiple directions on the roof frame, improving layout flexibility and ensuring compatibility with other roof equipment or structures, preventing obstruction or damage.

[0050] In this embodiment, as Figure 4 As shown, the first substrate 10 includes: a first plate segment 11 and a second plate segment 12, which are arranged at a preset included angle c. The second plate segment 12 is connected to the second substrate 20 and is arranged in the same plane. At least two third plate segments 13 are connected between the first plate segment 11 and the second plate segment 12 through at least two third plate segments 13. The preset included angle c satisfies: 2.5°≤c≤3.5°.

[0051] This design, with its preset angle c, provides flexibility for the layout of different vehicle-mounted devices, particularly optimizing the installation angles of equipment such as camera components and external fairings. This design helps the devices achieve optimal field-of-view coverage and airflow guidance, while ensuring coordination between devices and improving overall system efficiency. Furthermore, this design of the first substrate 10 not only adapts to the roof shapes of different vehicle models but also accommodates variations in the size and weight of devices such as sensors. The use of the preset angle c and the third plate segment 13 ensures that the roof frame maintains structural strength while possessing high equipment compatibility and vehicle model adaptability.

[0052] In this embodiment, the second substrate 20 includes: a fourth plate segment 21 and a fifth plate segment 22. The fourth plate segment 21 includes a first sub-plate 210 and a second sub-plate 211 arranged at an obtuse angle. The end of the first sub-plate 210 away from the second sub-plate 211 is connected to the second plate segment 12 and is arranged in the same plane. The fifth plate segment 22 is connected to the third plate segment 13 and is arranged parallel to the first sub-plate 210. The second sub-plate 211 is located on the side of the first sub-plate 210 closer to the fifth plate segment 22. At least two sixth plate segments 23 are connected between the fourth plate segment 21 and the fifth plate segment 22. The first plate segment 11, the second plate segment 12, the third plate segment 13, the fourth plate segment 21, the fifth plate segment 22 and the sixth plate segment 23 are integrally formed structures.

[0053] Thus, the obtuse angle arrangement of the first sub-plate 210 and the second sub-plate 211, along with the parallel design of the fifth plate segment 22, provides more flexible layout space for the roof-mounted equipment. This structure helps to rationally arrange the positions of sensors such as LiDAR and cameras, while ensuring that the equipment does not obstruct each other, guaranteeing the all-around perception capability of the autonomous vehicle. Furthermore, the integrated structural design ensures the structural integrity and strength of the entire mounting frame 1. This design reduces potential structural weaknesses caused by welding or bolted connections, improves the rigidity of the frame, and is beneficial for supporting various roof-mounted devices, maintaining stability even under extreme driving conditions. It also simplifies the production and assembly process of the second base plate 20, reduces the number of parts, and lowers manufacturing costs and installation time. This design makes the production process more efficient and the assembly process simpler, facilitating large-scale modification and mass production.

[0054] It is evident that the integrated structure of the first substrate 10 and the second substrate 20 not only improves the overall strength of the mounting frame 1 and the flexibility of equipment layout, but also simplifies the production and installation process, optimizes weight distribution and aerodynamic performance, and ultimately provides a solid technical foundation for the efficient modification, safe operation and continuous maintenance of unmanned vehicles.

[0055] In this application, the wall thickness h of the first substrate 10 and the second substrate 20 satisfies: 2.5mm ≤ h ≤ 3.5mm. This ensures sufficient structural strength of the mounting frame 1 to support roof-mounted equipment such as lidar and cameras, while effectively controlling weight and reducing the impact on vehicle balance and energy consumption. Furthermore, ensuring sufficient structural strength for the first substrate 10 and the second substrate 20 also reduces unnecessary material consumption.

[0056] In this embodiment, the second substrate 20 is provided with a mounting opening 24 for connection to external decorative components. This provides convenience for connection to external decorative components or other functional components, enhances the flexibility and versatility of equipment installation, and meets the needs of different vehicle models and application scenarios. The precise design of the mounting opening 24 facilitates rapid positioning and installation, improving modification efficiency.

[0057] In this embodiment, the end of the second substrate 20 furthest from the first substrate 10 is provided with an arc-shaped groove 25 to avoid the placement of external assembly components and to connect with at least a portion of the external assembly components. This arrangement, through the arc-shaped groove 25, avoids the external assembly components while also providing connection points with these components. This design avoids conflicts between the assembly components and the roof frame, ensuring the integrity and functionality of the roof components, while also providing more space for equipment integration.

[0058] In this embodiment, the first substrate 10 and the second substrate 20 are integrally formed structures and are both made of aluminum.

[0059] According to another aspect of the present invention, a vehicle is provided, including the aforementioned roof frame structure.

[0060] The roof frame structure provides a robust platform for mounting various sensors and devices, such as LiDAR and cameras, which are crucial for enabling autonomous driving. Through effective integration of the roof frame, the vehicle can better perceive its environment, plan its path, and make decisions and controls, thereby significantly improving the performance and safety of intelligent driving. Furthermore, the roof frame structure is designed to blend seamlessly with the vehicle's exterior. By using angled panel segments and unibody molding technology, it can better match the roof curves of different vehicle models, maintaining the vehicle's aesthetics. In addition, the lightweight design and optimized aerodynamic layout help reduce air resistance during driving, improve energy efficiency, reduce noise, and enhance overall aerodynamic performance.

[0061] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0062] A roof frame structure includes: a mounting frame 1, comprising a first base plate 10 and a second base plate 20; a first mounting component 30, at least a portion of which is disposed on the first base plate 10 and at least another portion of which is disposed on the second base plate 20, the first mounting component 30 being used to connect to a lidar component; and a second mounting component 40, disposed on the first base plate 10, at least a portion of which is used to connect to a camera component; wherein at least a portion of the mounting frame 1 is a hollow structure; along a direction perpendicular to the surface of the mounting frame 1, the cross-sectional shape of the first base plate 10 is different from the cross-sectional shape of the second base plate 20, and the cross-sectional width of the first base plate 10 is greater than the cross-sectional width of the second base plate 20.

[0063] Through this application, the mounting frame 1 adopts a hollow structure design, which can significantly reduce the overall weight of the mounting frame 1 while maintaining sufficient rigidity and strength, facilitating vehicle modification operations and ensuring the stability of the roof-mounted equipment under high-speed driving and harsh road conditions. The special layout of the first mounting component 30, with one part set on the first base plate 10 and the other part on the second base plate 20, allows for flexible installation of the LiDAR component on the roof frame, optimizing space utilization and enhancing the versatility of the mounting frame 1. It can adjust the sensor position according to the characteristics of different vehicle models, thereby ensuring optimal detection range and viewing angle, and improving the perception capability of the autonomous driving system. The second mounting component 40 is directly set on the first base plate 10, and a specially designed portion is used for connection with the camera component, which not only simplifies the equipment installation steps but also ensures the precise positioning of the camera component. Since the camera component is crucial for the accuracy of environmental perception, this design helps to avoid field of view obstruction or angular deviation caused by installation errors, thereby ensuring the safe operation of the autonomous vehicle. Furthermore, by employing the different cross-sectional shapes of the first substrate 10 and the second substrate 20, and the design feature that the cross-sectional width of the first substrate 10 is greater than that of the second substrate 20, different cross-sectional shapes can provide customized support strength for different areas of the roof. A larger cross-sectional width means stronger load-bearing capacity and more stable connection performance, which directly improves the overall performance of the roof frame, making it more adaptable to various complex working conditions. It is evident that the mounting frame 1 of this application improves the product's integration, facilitating mass production for retrofits, and thus solving the technical problem of low overall rigidity and integration in existing roof frame structures, which hinders vehicle modification operations.
