[0001] The invention relates to the technical field of automobile parts, and in particular to an integrated mounting bracket and a vehicle. Background Art

[0002] With the acceleration of the process of automobile intelligence, intelligent driving technology has ushered in rapid development. As the core sensor for environmental detection, the layout of automotive lidar needs to comprehensively consider multi-dimensional factors such as styling design, space utilization, heat dissipation efficiency and optical path planning. Improper layout schemes may not only cause NVH performance degradation, data collection distortion and other problems, but also have a significant impact on the overall performance of the vehicle.

[0003] In the prior art, the roof is the mainstream placement location for LiDAR. However, this arrangement has multiple defects: First, the structure protruding from the roof destroys the streamlined design of the vehicle, which not only affects the appearance, but also causes an increase in the drag coefficient, which in turn has an adverse effect on the vehicle's range. Second, due to long-term exposure to the external environment, LiDAR faces the risk of rain infiltration and dust accumulation, which may cause contamination of optical components or failure of electronic components. Third, the roof structure needs to be disassembled for repair and maintenance, which is complicated and time-consuming, and the user experience is not good. Summary of the invention

[0004] The purpose of the present invention is to provide an integrated mounting bracket and a vehicle, which can realize the integrated arrangement of a laser radar, a camera, and an interior rearview mirror.

[0006] Furthermore, the bracket body includes a base plate, a side panel extending upward from the side of the base plate, and a fixing plate extending outward from the top of the side panel. The base plate is provided with at least one first mounting hole for fixing the laser radar, and the fixing plate is fixedly connected to the inner side of the front cross beam of the vehicle body roof.

[0007] Further, the substrate is rectangular; a first notch for avoiding the detection channel of the lidar is provided at the upper edge of the front side plate extending upward from the front side edge of the substrate; second notches are provided at the upper edges of the left side plate and the right side plate extending upward from the left and right side edges of the substrate; first heat dissipation holes and first through holes for the wire harness to pass through are provided on the rear side plate extending upward from the rear side edge of the substrate; and second heat dissipation holes are provided on the substrate.

[0008] Further, first reinforcing ribs are provided between the left side plate and the fixing plate, and between the right side plate and the fixing plate, and second reinforcing ribs are provided on the upper surface of the substrate.

[0009] Further, at least two second mounting holes for fixing to the inner side of the front cross member of the vehicle body roof are provided on the fixing plate, and one of the second mounting holes is a circular hole as the main positioning hole, one of the second mounting holes is a strip-shaped hole as the secondary positioning hole, and the remaining second mounting holes are all circular holes.

[0010] Further, the first mounting portion includes a mounting box body connected to the front side of the bracket body, and an avoidance through hole for avoiding the acquisition end of the camera is provided on the front side of the mounting box body; the mounting box body extends horizontally outward from the front side of the bracket body, exposing the rear side surface of the mounting box body, so that the camera and the lidar are arranged horizontally at intervals. A second through hole for the wire harness to pass through is provided on the rear side surface of the mounting box body.

[0011] Further, third reinforcing ribs are provided on the outer surface of the mounting box body.

[0012] Further, the second mounting portion includes a base fixed to the bottom surface of the bracket body, third mounting holes for fixing the inner rearview mirror are provided on the bottom surface of the base, and fourth reinforcing ribs are provided between the side surface of the base and the bottom surface of the bracket body.

[0013] Further, a first positioning pin adapted to the first positioning hole on the lidar is provided on the bracket body, and a second positioning hole adapted to the second positioning pin on the camera is provided on the first mounting portion.

[0014] In a second aspect, the present invention discloses a vehicle, which includes the above integrated mounting bracket.

Moreover, the lidar, camera, and interior rear - view mirror are arranged in a layered or juxtaposed manner in the vertical direction (such as the height direction) or the horizontal direction (such as the left - right direction), shortening the physical distance between components and avoiding mutual interference. For example, the camera can be arranged adjacent to the left or right of the lidar, sharing the optical path and field of view, and improving the efficiency of sensor data fusion; the interior rear - view mirror is installed on the bottom surface, utilizing the space below the lidar and avoiding occupying the field - of - view area directly in front of the driver.

[0016] 2. The lidar of the present invention is hidden inside the front cross - beam of the vehicle body roof, without protruding above the roof or outside the vehicle body, maintaining the streamlined appearance of the whole vehicle, reducing the drag coefficient, and improving the vehicle's endurance. Compared with the external roof mounting solution, the integrated design inside the vehicle avoids the negative impact of the protruding structure on the aerodynamic performance, especially suitable for new - energy vehicle models pursuing low wind resistance. And since the lidar is integrated inside the vehicle, during maintenance, only interior components such as the ceiling trim cover need to be disassembled, without large - scale disassembly of the roof or external vehicle - body structure, reducing the maintenance complexity and time cost.

Detailed implementation manners

[0027] The following will describe the implementation manners of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention and not for limiting the protection scope of the present invention.

[0028] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. The drawings only show the components related to the present invention and are not drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0029] In one embodiment, the present invention provides an integrated mounting bracket, which includes a bracket body 1 fixed to the inner side of the front cross member 2 of the vehicle body roof. The bracket body 1 and the inner side of the front cross member 2 of the vehicle body roof enclose a box space for accommodating a lidar 3, and the lidar 3 is fixedly connected to the bracket body 1. A first mounting portion 11 for fixing a camera 4 is provided on the front side of the bracket body 1, and a second mounting portion 12 for fixing an interior rearview mirror 5 is provided on the bottom surface of the bracket body 1.

[0030] Through the design of the box space, the bracket body 1 of the present invention integrates the lidar 3 on the inner side of the front cross member 2 of the vehicle body roof. At the same time, the first mounting portion 11 is provided on the front side to fix the camera 4, and the second mounting portion 12 is provided on the bottom surface to fix the interior rearview mirror 5, forming a three-dimensional layout of "stacked up and down, side by side left and right". With this arrangement, multiple components that were traditionally installed independently are integrated into the same bracket, reducing redundant structures, significantly improving the utilization rate of the interior space of the vehicle, and simplifying the complexity of the interior layout. Moreover, the lidar 3, the camera 4, and the interior rearview mirror 6 are arranged in a layered or side-by-side manner in the vertical direction (such as the height direction) or the horizontal direction (such as the left and right directions), shortening the physical distance between the components and avoiding mutual interference. For example, the camera 4 can be arranged adjacent to the left or right side of the lidar 3 to share the optical path and field of view, improving the efficiency of sensor data fusion; the interior rearview mirror 5 is installed on the bottom surface, utilizing the space below the lidar 3 and avoiding occupying the field of view area directly in front of the driver.

[0031] The lidar 3 of the present invention is hidden inside the front cross member 2 of the vehicle body roof, without protruding above the roof or outside the vehicle body, maintaining the streamlined appearance of the whole vehicle, reducing the drag coefficient, and improving the vehicle's endurance. Compared with the external roof-mounted solution, the in-vehicle integrated design avoids the negative impact of the protruding structure on the aerodynamic performance, especially suitable for new energy vehicles pursuing low wind resistance. And because the lidar 3 is integrated inside the vehicle, during maintenance, only interior components such as the ceiling trim cover need to be disassembled, without large-scale disassembly of the roof or the external structure of the vehicle body, reducing the complexity and time cost of maintenance.

[0032] As a preferred embodiment of the present invention, the bracket body 1 includes a base plate 13, a side plate 14 extending upward from the side surface of the base plate 13, and a fixing plate 15 extending outward from the top end of the side plate 13. At least one first mounting hole 131 for fixing the lidar 3 is provided on the base plate 13, and the fixing plate 15 is fixedly connected to the inner side of the front cross member 2 of the vehicle body roof.

[0033] The substrate 13, side plate 14, and fixing plate 15 form a three-dimensional frame structure. The side plate 14 extends upward from the side of the substrate 13, and the fixing plate 15 extends outward from the top end of the side plate 14 and is fixedly connected to the inner side of the front cross member 2 of the vehicle body roof, constituting a stable support system. Furthermore, the gravity and vibration loads of the lidar 3 are transmitted to the vehicle body through the substrate 13, side plate 14, and fixing plate 15, reducing the risk of deformation due to single-point stress and enhancing the overall installation stiffness.

[0034] The height at which the side plate 14 extends upward can be flexibly adjusted according to the thickness of the lidar 3, so that the lidar 3 is arranged in the "non-driving and riding activity area" at the top of the vehicle interior, avoiding occupying the head space of the driver or passengers.

[0035] The fixing plate 15 is in planar contact with the front cross member 2 of the vehicle body roof, and the connection area is relatively large. It can be fixed through surface contact by means of bolts, welding, etc. Compared with the traditional single-point bolt connection, the stress distribution is more uniform, avoiding bracket fracture or vehicle body damage caused by local stress concentration. Moreover, the length at which the fixing plate 15 extends outward can be adapted to the installation position of the front cross member 2 of the vehicle body roof, so that the entire bracket body 1 is arranged close to the inner side of the front windshield 8, shortening the distance between the lidar 3 and the front windshield 8 and reducing the optical path transmission loss.

[0036] The side plate 14 and the substrate 12 form a semi-closed box structure. Cooperating with the fixing plate 15 to surround the vehicle body can protect the lidar 3 from being accidentally touched by vehicle occupants or collided by objects, while reducing dust deposition. At the same time, the natural frequency of the three-dimensional frame structure can avoid the main vibration frequencies during vehicle driving, reducing the risk of resonance. The rigid support of the side plate 14 can reduce the vibration amplitude of the lidar 3 to less than 1 / 2 of the independent installation scheme, avoiding laser point cloud jitter or camera image blur caused by vibration. Combining the surface contact connection between the fixing plate 15 and the vehicle body can block the transmission of high-frequency noise into the vehicle interior. Cooperating with the sound insulation design of the side plate 14, such as covering damping materials, can reduce the vehicle interior noise value by 5 - 8 dB, enhancing the driving and riding quietness.

[0037] Exemplarily, the fixing plate 15 is connected to the vehicle body by bolts. During maintenance, only the bolts of the fixing plate 15 need to be loosened to disassemble the entire bracket body 1 from the vehicle body. Compared with the traditional external roof-mounted scheme that requires complex steps such as disassembling the deflector and seal, the disassembly efficiency is improved.

[0038] Furthermore, the bracket body 1 is an integrally formed metal structure. The integrated frame structure reduces the number of components. At the same time, the integrated forming process of metal plates or cast aluminum (such as stamping, die casting) can improve production efficiency and reduce the unit manufacturing cost.

[0039] Furthermore, the number of the first mounting holes 131 is four, and the four first mounting holes 131 are respectively arranged at the four corners of the rectangular substrate 13 to form a rectangular four-point support structure, and the lidar 3 is stably fixed on the substrate 13 by bolts or screws. With such a layout, the fitting degree between the mounting surface of the lidar 3 and the plane of the substrate 13 can be improved, avoiding inclination or warping caused by single-point or two-point support, and ensuring the perpendicularity of the optical axis of the lidar 3 to the vehicle body coordinate system.

[0040] At the same time, the four-point mounting can effectively restrain the degrees of freedom of the lidar 3 in the three-dimensional space. Compared with two-point or three-point mounting, the positioning accuracy of the lidar 3 is improved, which is especially suitable for lidars that are sensitive to the mounting angle.

[0041] Moreover, the weight and vibration load of the lidar 3 are evenly transmitted to the substrate 13 through the first mounting holes 131 at the four corners, avoiding deformation of the substrate 13 caused by excessive local stress and ensuring the mounting stability of the lidar 3 under long-term use.

[0042] As a preferred embodiment of the present invention, the substrate 13 is rectangular; a first notch 145 for avoiding the detection channel of the lidar 3 is provided at the upper edge of the front side plate 141 extending upward from the front side edge of the substrate 13; second notches 146 are provided at the upper edges of the left side plate 142 and the right side plate 143 extending upward from the left and right side edges of the substrate 13; a first heat dissipation hole 147 and a first through hole 148 for the wire harness to pass through are provided on the rear side plate 144 extending upward from the rear side edge of the substrate 13.

[0043] The first notch 145 provided at the upper edge of the front side plate 141 corresponds to the detection direction of the lidar 3, that is, the front horizontal field of view, avoiding the front side plate 141 from blocking the light beam emitted or received by the lidar 3 and ensuring the smoothness of the detection channel. For example, the width and height of the first notch 145 can cover the edge ranges of the horizontal field of view angle and the vertical field of view angle of the lidar, improving the light beam passing rate and avoiding detection blind spots or data distortion caused by structural occlusion. It should be noted that the shape and position of the first notch 145 can be customized according to the optical design of the lidar 3 (such as the position of the emission window and the light beam divergence angle), for example, in a trapezoidal or arc shape, ensuring a safety distance between the edge of the light beam and the edge of the notch to avoid interference with the detection accuracy caused by light beam reflection or diffraction.

[0044] The substrate 13 is provided with a second heat dissipation hole 132 to accelerate the air convection at the bottom of the lidar 3. Cooperating with the heat conduction pad or metal substrate of the lidar 3 itself, the heat is conducted to the vehicle interior environment through the holes, that is, the first heat dissipation hole 147 and the second heat dissipation hole 132, avoiding a decrease in the frame rate or a decrease in the detection distance of the lidar 3 caused by overheating.

[0045] The second notches 146 provided at the upper edges of the left side plate 142 and the right side plate 143 play a role in heat dissipation and weight reduction, further ensuring the heat dissipation efficiency of the lidar, and at the same time reducing the overall weight of the bracket body 1, meeting the requirements of vehicle body lightweighting.

[0046] The first through holes 148 provided on the rear side plate 144 provide dedicated channels for the power supply wires and signal wires of the lidar 3, avoiding friction and wear between the wire harness and the edge of the side plate 14, and at the same time fixing the wire harness routing, reducing the risk of poor contact caused by wire harness shaking. A rubber sealing ring can be installed in the first through holes 148 to improve the dust-proof and sound-insulating effects.

[0047] After the wire harness is led out through the first through holes 148, it can be arranged along the inner side of the rear side plate 144 or the bottom surface of the substrate 13, and cooperate with the ceiling decorative cover to block, keeping the interior trim clean and avoiding the wire harness being exposed to affect the appearance or causing accidental touch by the user.

[0048] It should be noted that the front, rear, left, and right edges of the rectangular substrate 13 can be appropriately extended or narrowed according to the contour of the front cross beam 2 of the vehicle body roof. For example, the distance between the front side plate 141 and the front windshield 8 is kept at 20-30 mm, avoiding interfering with the movement area of the windshield wiper, and at the same time ensuring that the included angle between the detection beam of the lidar 3 and the glass normal line ≤ 15°, reducing the refraction error.

[0049] Although the box space formed by the side plate 14 and the substrate 13 has the first notch 145 and the second notch 146, it can still prevent the floating dust in the vehicle from directly falling on the optical window of the lidar as a whole.

[0050] Through the detailed designs such as the optical path avoidance notch, multi-channel heat dissipation holes, and wire harness management through holes, this preferred embodiment specifically solves the core problems such as detection occlusion, heat dissipation bottleneck, and wire harness clutter of the lidar 3 without sacrificing the structural strength.

[0051] As a preferred embodiment of the present invention, a first reinforcing rib 149 is provided between the left side plate 142 and the right side plate 143 and the fixing plate 15, and a second reinforcing rib 133 is provided on the upper surface of the substrate 12.

[0052] The first reinforcing rib 149 connects the side plate 14 and the fixing plate 15 to form a triangular support structure of "side plate - reinforcing rib - fixing plate", and distributes the load borne by the side plate 14 (such as the gravity and vibration impact force of the lidar 3) to the connection area between the fixing plate 15 and the vehicle body through the first reinforcing rib 149. With this setting, the anti-bending stiffness of the bracket body 1 is improved, and deformation or fracture due to stress concentration at the connection between the side plate 14 and the fixing plate 15 is avoided.

[0053] The second reinforcing rib 133 is arranged along the upper surface of the substrate 13 (i.e., the mounting surface of the lidar 3), enhancing the support stiffness of the substrate 13 for the lidar 3. Especially when the lidar 3 is relatively heavy, it reduces the sagging deformation in the middle of the substrate 13, ensures the flatness of the mounting surface of the lidar 3, and avoids the optical axis deviation of the lidar 3 caused by the deformation of the substrate 13.

[0054] As a preferred embodiment of the present invention, at least two second mounting holes 151 for fixing to the inner side of the front cross member 2 of the vehicle body roof are provided on the fixing plate 15. One of the second mounting holes 151 is a circular hole as the main positioning hole, one of the second mounting holes 151 is a strip-shaped hole as the secondary positioning hole, and the remaining second mounting holes 151 are all circular holes.

[0055] The main positioning hole realizes the absolute positioning of the bracket body in three-dimensional space by corresponding cooperation with the fasteners on the front cross member 2 of the vehicle body roof, ensuring the reference accuracy of the mounting surface of the substrate 13. The main positioning hole can limit the translational degrees of freedom of the X / Y / Z axes of the bracket body 1, avoiding deviation during the installation process.

[0056] The secondary positioning hole extends along a specific direction (such as the vehicle length direction or width direction), allowing the bracket body 1 to have a small adjustment space in this direction, which is used to compensate for the body manufacturing tolerance, improve the first-pass rate of the installation of the bracket body 1, and avoid installation interference caused by body tolerance.

[0057] Exemplarily, the number of the second mounting holes 151 is four. Two second mounting holes 151 are arranged at the front and rear ends of the right fixing plate 15, and the other two second mounting holes 151 are arranged at the front and rear ends of the left fixing plate 15. One of the two second mounting holes 151 at the rear end is used as the main positioning hole, and the other is used as the secondary positioning hole.

[0058] As a preferred embodiment of the present invention, the first mounting portion 11 includes a mounting box body connected to the front side of the bracket body 1. An avoidance through hole 111 for avoiding the acquisition end of the camera 4 is provided on the front side of the mounting box body; the mounting box body extends horizontally outward from the front side of the bracket body 1, exposing the rear side surface of the mounting box body, so that the camera 4 and the lidar 3 are arranged horizontally at intervals, avoiding the optical path occlusion caused by their vertical stacking. The horizontal interval design reduces the electromagnetic interference between the camera 4 and the lidar 3, avoiding image noise or data jump.

[0059] The shape of the avoidance through-hole 111 matches the contour of the acquisition end (such as the lens) of the camera 4 (such as circular or square), and a safety gap is reserved for the aperture size. For example, the aperture of the avoidance through-hole 111 is 2-3 mm larger than the outer diameter of the lens of the camera 4 to ensure unobstructed vision of the camera 4. At the same time, the edge of the avoidance through-hole 111 is treated to prevent scratching, such as by chamfering the corners, to avoid scratching the lens protection glass during installation.

[0060] A second through-hole 112 for the harness to pass through is provided on the rear side of the installation box body, providing a dedicated channel for the harness of the camera 4 (such as a video cable and a power cable). A rubber wire protection sleeve can be installed in the second through-hole 112 to prevent the harness from rubbing and wearing against the metal edge, and at the same time improve the dust-proof effect.

[0061] The camera 4 is quickly connected to the installation box body by a buckle or a bolt. During maintenance, only the fastener at the front end of the installation box body needs to be loosened, and the camera 4 can be disassembled separately without touching the lidar 3 or the bracket body 1, improving the after-sales replacement efficiency of the camera 4, especially suitable for intelligent driving models that require frequent camera configuration upgrades.

[0062] Further, the connection between the installation box body and the front side of the bracket body 1 adopts an integrated design, such as cast aluminum die-casting, which can withstand the vibration load of the camera 4 and can prevent dust from directly falling on the lens surface.

[0063] As a preferred embodiment of the present invention, a third reinforcing rib 113 is provided on the outer surface of the installation box body.

[0064] The third reinforcing rib 113 is arranged along the stress concentration areas on the outer surface of the installation box body, such as the edge of the box body and the periphery of the avoidance through-hole, forming a "support structure" and improving the bending stiffness of the installation box body. The third reinforcing rib 113 and the installation box body are integrally formed by an injection molding or die-casting process, with high connection strength, capable of withstanding accidental impact loads, and avoiding cracking or breaking of the box body.

[0065] And due to the setting of the third reinforcing rib 113, the natural frequency of the installation box body can also be adjusted to avoid the working frequency of the motor of the camera 4, reducing the risk of resonance and avoiding image blurring or data jitter.

[0066] As a preferred embodiment of the present invention, the second mounting portion 12 includes a base 121 fixed to the bottom surface of the bracket body 1. The bottom surface of the base 121 is provided with a third mounting hole 122 for fixing the interior rearview mirror 5. A fourth reinforcing rib 123 is provided between the side surface of the base 121 and the bottom surface of the bracket body 1.

[0067] The base 121 is fixed to the bottom surface of the bracket body 1 and is bolted to the interior rearview mirror 5 through the third mounting hole 122, forming a surface contact rigid support. Compared with the solution of directly opening a hole on the bottom surface of the bracket body 1 for installation, the base 121 can evenly conduct the load of the interior rearview mirror 5 (such as gravity and pulling force during adjustment) to the bracket body 1, avoiding cracking due to local stress on the bottom surface.

[0068] The position of the third mounting hole 122 is precisely matched with the mounting interface of the interior rearview mirror 5 to ensure that the error between the mirror normal line and the driver's line of sight is ≤2°, avoiding insufficient rearview vision caused by installation deviation.

[0069] The fourth reinforcing rib 123 is provided between the side surface of the base 121 and the bottom surface of the bracket body 1 to form a "triangular support structure", which improves the structural strength of the base 121 and ensures the stability of the mirror angle of the interior rearview mirror 5. At the same time, the setting of the fourth reinforcing rib 123 can adjust the natural frequency of the bottom of the bracket body 1 to avoid the vehicle idle vibration frequency and reduce the jitter of the interior rearview mirror caused by resonance.

[0070] The base 121 is arranged by using the "non-sensitive area" on the bottom surface of the bracket body 1, avoiding occupying the head space of the driver and passengers. At the same time, the installation height of the interior rearview mirror 5 is the same as that of the traditional layout, meeting the ergonomic design.

[0071] The base 121 and the bracket body 1 can be integrally formed by injection molding or die casting, reducing the assembly process. At the same time, the connection strength between the fourth reinforcing rib 123, the base 121 and the bracket body 1 is ensured, avoiding the risk of loosening.

[0072] Furthermore, the base 121 is a double-layer boss structure. The lower boss is directly attached to the mounting seat of the interior rearview mirror 5, and the upper boss expands the contact area with the bottom surface of the bracket body 1. Then, the load of the interior rearview mirror 5 is evenly conducted to the bracket body 1 through the double-layer structure, avoiding deformation caused by concentrated stress in the single-layer structure. The step distance between the upper and lower bosses matches the thickness of the mounting flange of the interior rearview mirror 5 to form an embedded positioning, which can inhibit the front-back and left-right displacement of the interior rearview mirror 5 during vehicle driving and ensure the stability of the mirror angle.

[0073] As a preferred embodiment of the present invention, a first positioning pin 16 adapted to the first positioning hole on the lidar 3 is provided on the bracket body 1, and a second positioning hole 17 adapted to the second positioning pin on the camera 4 is provided on the first mounting portion 11.

[0074] With such a setting, the installation position accuracy of the lidar 3 and the camera 4 is ensured. Moreover, the tight fit between the positioning pins and the holes can suppress the micro-displacement of the lidar 3 and the camera 4 in a vibration environment, avoiding the optical axis deviation or data drift caused by the displacement. In addition, during subsequent maintenance, the first positioning pin 16 and the second positioning hole 17 can be used as a reset reference to ensure that the position of the device reinstalled after disassembly is consistent with the original position.

[0075] In one embodiment, the present invention provides a vehicle, which includes the above integrated mounting bracket.

[0076] The vehicle provided by the embodiment of the present invention can be, but is not limited to, a sedan, a truck, a pickup truck, a commercial vehicle, a bus, and a SUV. The present application does not make any restrictions on this. The vehicle includes a bracket body 1, a body roof crossbeam 2, a lidar 3, a camera 4, an interior rearview mirror 5, a decorative member 7, and a windshield 8.

[0077] The rear end of the windshield 8 is lapped and fitted with the body roof crossbeam 2, and the bracket body 1, the lidar 3, the camera 4, the interior rearview mirror 5, and the decorative member 7 are all located in the vehicle interior space.

[0078] The lidar 3 is installed on the bracket body 1. The detection channel of the lidar 3 faces the windshield 8, and the detection signals emitted and received by the lidar 3 pass through the windshield 8. Specifically, the detection signals emitted by the lidar 3 can pass through the windshield 8 to detect the vehicle's external environment. The part of the detection signals reflected by the objects in the external environment can pass through the windshield 8 again and be received by the lidar 3, so that the lidar 3 can sense the vehicle's external environment information. Similarly, the camera 4 is used to capture and identify the vehicle's external environment information to implement functions such as vehicle recognition, pedestrian recognition, and lane line recognition. The decorative member 7 is used to cover the bracket body 1, the lidar 3, and the camera 4 to improve the aesthetics of the vehicle interior. The interior rearview mirror 5 is fixed to the bracket body 1, and the mirror body part of the interior rearview mirror 5 passes through the decorative member 7 and extends into the vehicle interior, so that passengers or drivers can obtain the environmental information behind the vehicle through the interior rearview mirror 5.

[0079] The above embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
