[0003] In related technologies, environmental perception components such as visual lidar and cameras are usually mounted on the roof of a vehicle using brackets, which is relatively inconvenient to install. Summary of the Invention

[0004] This application provides a bracket assembly and a vehicle to solve the technical problem in the related art that environmental sensing elements such as visual lidar and cameras are usually installed on the roof of a vehicle via brackets, which is relatively inconvenient to install.

[0005] In a first aspect, embodiments of this application provide a support assembly, including:

[0006] A windshield base is disposed on the upper inner side of the windshield and has a mounting surface facing the vehicle cabin, the mounting surface being provided with a pre-attached component;

[0007] A bracket has an assembly position for installing an environmental sensing component. The bracket also includes a mating component offset from the assembly position, which mates with a pre-mounted component, allowing the bracket to be mounted on the windshield base.

[0008] A fixing structure is used to connect the windshield base and the bracket, and to fix the bracket to the windshield base after it is mounted.

[0009] In some embodiments, the pre-attached component includes a hook disposed on the mounting surface, the hook head being configured to extend upward along the tilt direction of the windshield;

[0010] The mating component includes a mating hole formed in the bracket, the depth direction of the mating hole being the same as the extension direction of the hook head, and the mating hole allowing the hook head of the hook to pass through.

[0011] In some embodiments, at least two mating holes are provided, and the at least two mating holes are located on both sides of the assembly position in the lateral direction; at least two hooks are provided, and the at least two hooks correspond one-to-one with the at least two mating holes; and / or,

[0012] In the normal direction of the mounting surface, the size of the mating hole is larger than the size of the hook head.

[0013] In some embodiments, the bracket has a fixing surface, the fixing surface and the mounting position are spaced apart in a direction away from the mounting surface, and the bracket has a plurality of first through holes penetrating the fixing surface;

[0014] The mounting surface is provided with a plurality of first screw holes, and the plurality of first screw holes correspond one-to-one with the plurality of first through holes;

[0015] The fixing structure includes a plurality of fixing screws, and the plurality of fixing screws, the plurality of first through holes and the plurality of first screw holes correspond one-to-one. Each fixing screw passes through the corresponding first through hole and is threadedly connected to the windshield base via the corresponding first screw hole.

[0016] In some embodiments, the mounting surface protrudes towards the bracket with a plurality of mounting platforms, each of the plurality of mounting platforms corresponding to a plurality of the first through holes, and each of the mounting platforms having a first screw hole.

[0017] In some embodiments, the fixing surface is further provided with two limiting grooves, the extending directions of the two limiting grooves intersect, and each limiting groove is provided with the first through hole;

[0018] The mounting platform corresponding to the limiting groove can extend into the corresponding limiting groove, and in the extension direction of each limiting groove, the size of the corresponding mounting platform is smaller than the size of the limiting groove.

[0019] In some embodiments, the two first through holes are surrounded by a first rib at one end of the fixed surface, and the two first ribs intersect in their extending directions and respectively surround to form two limiting grooves.

[0020] In some embodiments, the bracket has an opening at least at the mounting position in a direction away from the windshield base; and / or,

[0021] The bracket has multiple second ribs on the side opposite to the windshield base, and the multiple second ribs are connected in an interlaced manner.

[0022] In some embodiments, the bracket has a fixing buckle on at least one side of the assembly position in the transverse direction, the fixing buckle being used to install a wire harness clip.

[0023] Secondly, this application also provides a vehicle, comprising:

[0024] The bracket assembly as described in any of the preceding claims, wherein the bracket assembly comprises a plurality of frame bodies, the plurality of frame bodies being integrally formed and each having an assembly position; and

[0025] An environmental sensing component includes multiple environmental sensing elements, which are respectively disposed on multiple frames.

[0026] In the bracket assembly provided in this embodiment, the windshield base is located inside the windshield. Assembly is performed from inside the cabin. Because the pre-attached component is located on the side of the windshield base facing the cabin, the assembly personnel can intuitively and quickly confirm its position from inside the cabin. After confirming the position of the pre-attached component, the assembly personnel bring the pre-installed environmental sensing component bracket close to the windshield base and align the bracket's mating parts with the pre-attached component on the windshield base. During the process of bringing the bracket close to the windshield base, the staggered assembly positions of the mating parts and the bracket effectively prevent interference between the pre-attached component, the mating parts, and the environmental sensing element during assembly, reducing the risk of damage to the environmental sensing element, meeting the installation space requirements of the environmental sensing component, and achieving effective installation.

[0027] Thus, this solution allows the bracket to be mounted on the windshield base through the cooperation of pre-mounted parts and mating parts. The mounting process provides a good field of vision, enables quick temporary positioning of the bracket, frees up the assembly personnel's hands, and improves assembly flexibility. At the same time, it also enables the auxiliary alignment of the windshield base and the bracket, which facilitates the subsequent assembly and fixing of the structure, improves assembly accuracy, and shortens assembly time. This enhances the ease of installation of the environmental sensing element and improves assembly efficiency. Attached Figure Description

[0045] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] In related technologies, environmental sensing components such as visual lidar and cameras are typically mounted on the roof of a vehicle using brackets. On the one hand, because there are many related components around the roof, it is necessary to first remove the trim panels, sun visors, and sealing strips. The disassembly and assembly process must avoid scratching or damaging these components, which is time-consuming and inconvenient. On the other hand, since the brackets are usually fixed with bolts, one person needs to support the bracket while another person operates the tools during assembly. As a result, bracket installation is relatively inconvenient.

[0048] Please see Figures 1 to 3 This application provides a bracket assembly, including a windshield base 1, a bracket 2, and a fixing structure 4; the windshield base 1 is disposed on the upper inner side of the windshield 6 and has a mounting surface 11 facing the vehicle cabin, the mounting surface 11 is provided with a pre-attached part 12; the bracket 2 has an assembly position 21 for installing an environmental sensing component 5, the bracket 2 is also provided with a mating part 22 offset from the assembly position 21, the mating part 22 can mate with the pre-attached part 12 and hang the bracket 2 on the windshield base 1; the fixing structure 4 is used to connect the windshield base 1 and the bracket 2 and fix the mounted bracket 2 to the windshield base 1.

[0049] In this design, the windshield base 1 is located inside the windshield 6. Assembly is performed from inside the cabin. Since the pre-attached component 12 is located on the side of the windshield base 1 facing the cabin, the assembly personnel can quickly and intuitively confirm its position from inside the cabin. After confirming the position of the pre-attached component 12, the assembly personnel bring the pre-installed bracket 2 of the environmental sensing component 5 close to the windshield base 1 and align the mating part 22 of the bracket 2 with the pre-attached component 12 on the windshield base 1. During the process of bringing the bracket 2 closer to the windshield base 1, the mating part 22 and the mounting position 21 of the bracket 2 are staggered, effectively preventing interference between the pre-attached component 12, the mating part 22, and the environmental sensing element 51 during assembly. This reduces the risk of damage to the environmental sensing element 51, meets the installation space requirements of the environmental sensing component 5, and achieves effective installation.

[0050] Thus, this solution allows the bracket 2 to be mounted on the windshield base 1 through the cooperation of the pre-mounted part 12 and the mating part 22. The mounting process provides a good field of vision, enables the temporary positioning of the bracket 2 quickly, frees up the hands of the assembly personnel, and improves the assembly flexibility. At the same time, it also enables the auxiliary alignment of the windshield base 1 and the bracket 2, which facilitates the subsequent assembly of the fixing structure 4, improves the assembly accuracy, and shortens the assembly time. This improves the ease of installation of the environmental sensing element 51 and increases the assembly efficiency.

[0051] It should be noted that the windshield base 1 on the inner upper side of the windshield 6 is usually pre-installed on the vehicle body to provide a precise installation reference for the upper edge of the windshield 6. It is tightly fitted to the windshield 6 through snap-fitting, adhesive, or other methods to prevent the windshield 6 from loosening or shifting during driving and to ensure that the installation position meets visibility requirements. Specifically, the windshield base 1 connects with components such as the front roof crossbeam of the vehicle body, enhancing the body rigidity around the windshield 6, dispersing vibrations and external forces during driving, and protecting the windshield 6 from breakage.

[0052] In this application, please refer to Figure 2 , Figure 3 and Figure 4Since the environmental sensing component 5 is mounted on the inside of the windshield base 1 via the bracket 2, it is essentially built into the vehicle cabin. On one hand, compared to an externally mounted component, this built-in design optimizes wind resistance and eliminates the need for ladders or other external mounting components, resulting in a more aesthetically pleasing exterior design. On the other hand, when the environmental sensing component 5 includes an external camera 53 for acquiring external images, the camera 53 can obtain these images through the windshield 6, providing a better field of view. Furthermore, the relatively stable environment within the vehicle cabin enhances the reliability and lifespan of the environmental sensing component 5.

[0053] It should be understood that the windshield base 1 used for mounting bracket 2 in this application can be a windshield base 1 used for mounting the front windshield (front windshield glass), or a windshield base 1 used for mounting the rear windshield (rear windshield glass), or the bracket 2 in this case can be installed on the windshield base 1 corresponding to the front windshield and the rear windshield respectively.

[0054] Specifically, please refer to Figure 4 In this design, the windshield base 1 is the windshield base 1 corresponding to the front windshield. Furthermore, in one embodiment, the bracket assembly also includes an interior rearview mirror cover 8. After the bracket 2 is assembled onto the windshield base 1, the interior rearview mirror cover 8 is placed over the lower side of the bracket 2, and an interior rearview mirror 81 is installed on the lower side of the interior rearview mirror cover 8. The interior rearview mirror cover 8 can be connected to the windshield base 1 (or bracket 2), and the interior rearview mirror cover and the windshield base 1 (or bracket 2) are connected by snap-fit ​​or bolts. In this way, the space at the windshield base 1 position can be shared with the interior rearview mirror 81, improving space utilization. It eliminates the need for separate mounting carriers for the bracket 2 and the interior rearview mirror cover 8, reducing the windshield view occupied by the mounting carrier, thereby reducing light path obstruction, minimizing the black area on the glass, improving the driving experience, and increasing safety.

[0055] It should be noted that, in one embodiment, the pre-attached component 12 and the mating component 22 are configured as a latching protrusion and a latching groove. In this embodiment, a latching protrusion is provided on the windshield base 1, extending towards the bracket 2, and the latching protrusion has a certain elastic deformation in the radial direction. This elastic deformation requires the assembler to apply a certain external force. Correspondingly, a latching groove is provided on the bracket 2 corresponding to the latching protrusion. Thus, during assembly, the latching groove of the bracket 2 is aligned with the latching protrusion, and the bracket 2 is brought close to the windshield base 1 until the latching protrusion deforms and extends into the latching groove, thereby enabling the bracket 2 to be mounted on the windshield base 1.

[0056] In another embodiment, the pre-attachment 12 and the mating part 22 are configured as magnetically pre-attached components. In this embodiment, the pre-attachment 12 can be configured as a partial magnetically adsorbable area of ​​the windshield base 1, or the entire windshield base 1 can constitute the pre-attachment 12. Correspondingly, the windshield base 1 can be partially made of a magnetically adsorbable material such as iron, cobalt, or nickel, or the entire windshield base 1 can be made of a magnetically adsorbable material such as iron, cobalt, or nickel. Specifically, in this embodiment, the entire windshield base 1 is made of sheet metal such as low-carbon steel plate. The mating part 22 is configured as a magnet that can be detached from the bracket 2. During assembly, the magnet is placed on the side of the bracket 2 away from the mounting surface 11, so that the bracket 2 is pre-attached to the windshield base 1. After the bracket 2 is fixed to the windshield base 1 via the fixing structure 4, the magnet is then removed from the bracket 2. It should be understood that the magnet and the bracket 2 can be snapped together or magnetically connected.

[0057] In yet another embodiment, please refer to Figure 2 and Figure 5 The pre-attached component 12 includes a hook 121 provided on the mounting surface 11, and the hook head 122 of the hook 121 is configured to extend upward along the inclined direction of the windshield 6; the mating component 22 includes a mating hole 22a formed in the bracket 2, the depth direction of the mating hole 22a is the same as the extension direction of the hook head 122 of the hook 121, and the mating hole 22a allows the hook head 122 of the hook 121 to pass through.

[0058] In this embodiment, the pre-hanging component 12 is set as a hook 121 on the mounting surface 11, and the hook head 122 extends upward along the inclined direction of the windshield. At this time, the hook opening of the hook 121 faces upward, so that when the hook head 122 passes through the mating hole 22a on the bracket 2, the bracket 2 is stably placed on the hook 121 under its own weight and will not detach. At the same time, during the assembly process, it is only necessary to roughly align the hook head 122 with the mating hole 22a, which is simple and convenient to operate and has good stability. It should be understood that the above-mentioned hook opening refers to the gap between the hook head 122 and the mounting surface 11, which is used for the bracket 2 to pass through the part with the mating hole 22a.

[0059] Specifically, hook 121 offers a higher tolerance for assembly errors compared to snap-fit ​​pre-attachment. Snap-fit ​​pre-attachment typically requires precise alignment of the upper / lower or left / right slots; significant deviations prevent assembly. Hook 121, with its hook opening and L-shaped or hook-like structure, allows for some assembly deviation, enabling simple hooking for pre-positioning and significantly reducing worker workload. Furthermore, snap-fit ​​connections use an interference fit, requiring forceful prying for disassembly after pre-attachment, which can easily damage the base or bracket 2; hook 121, with its one-way snap-fit ​​design, allows for easy disassembly by gently pulling in a specific direction, minimizing component damage. In this design, hook 121 is L-shaped.

[0060] Furthermore, compared to magnetic pre-attachment, the hook 121 is less affected by the environment and offers superior stability. Magnetic attachment is susceptible to sheet metal coatings, dust, and vibration. The hook 121, with its mechanical locking structure, is less prone to shifting after attachment and remains fixed even during vehicle vibrations. Additionally, the hook 121 requires no additional magnetic components, resulting in lower costs. Specifically, the hook 121 can be directly integrated with the windshield base 1, requiring no additional accessories.

[0061] In one embodiment, please refer to Figure 5 and Figure 6 There are at least two mating holes 22a, and the at least two mating holes 22a are located on both sides of the assembly position 21 in the horizontal direction. There are at least two hooks 121, and the at least two hooks 121 correspond one-to-one with the at least two mating holes 22a.

[0062] In this embodiment, mating holes 22a are provided on both sides of the assembly position 21, and hooks 121 are correspondingly provided. This ensures that the load-bearing assembly position 21 of the bracket 2 is subjected to balanced forces on both sides in the lateral direction, forming symmetrical support and distributing the weight of the bracket 2 itself and the external forces during assembly. Compared with a single hook 121, the bracket 2 is less prone to tilting or swaying, maintaining a temporary fixed state and reducing the risk of detachment. At the same time, it can quickly calibrate the lateral position of the bracket 2, avoiding left and right offsets and providing positioning for the subsequent assembly of the fixing structure 4. Moreover, multiple hooks 121 provide multiple layers of protection. Even if one hook 121 experiences slight wear due to long-term use, the remaining hooks 121 can still maintain their pre-attachment function, preventing the bracket 2 from falling off due to the failure of a single hook 121. Furthermore, the force-distributing design of the hooks 121 on both sides can extend the service life of the components and adapt to the complex working conditions of long-term automotive use.

[0063] It should be noted that in this embodiment, two mating holes 22a and two hooks 121 are provided respectively. Furthermore, the L-shaped hooks 121 in this design use columnar hook heads 122 with rounded ends. The arc surface or cylindrical side of the columnar hook head 122 provides a natural guiding function, eliminating the need for precise angle alignment during assembly; it can be quickly engaged through sliding of the contact surface. The contact area is relatively concentrated and smooth, allowing for easy disassembly by simply pushing or rotating along the axial direction. Compared to hook heads with sharp edges, this reduces friction and jamming with the mating holes 22a, lowering the risk of component wear.

[0064] Furthermore, it should be noted that the lateral direction of the mounting position 21 is the same as that of the vehicle during normal driving, indicated by F in the accompanying drawings. Thus, both the mating hole 22a and the hook 121 are located on either side of the lateral direction of the mounting position 21, reducing the obstruction of the environmental visual perception components along the vehicle's longitudinal direction and improving the perception field of view. It should be understood that the longitudinal direction of the vehicle refers to the direction of travel.

[0065] In one embodiment, the size of the mating hole 22a is larger than the size of the hook head 122 in the normal direction of the mounting surface 11.

[0066] In this embodiment, the dimension of the hook 122 along the normal direction of the mounting surface 11 is set to be smaller than the dimension of the mating hole 22a along the normal direction of the mounting surface 11. This allows for some adjustment along the normal direction of the mounting surface 11 after the bracket 2 is mounted on the windshield base 1, improving flexibility. In mass production of automotive parts, there may be slight dimensional errors in the hole positions and the hook 122, and the mounting surface 11 may also have a slight tilt. The reserved gap can absorb these deviations, avoiding assembly jamming and installation failures caused by interference fits. Simultaneously, the smaller size of the hook 122 compared to the mating hole 22a also creates a reasonable gap, allowing for quick docking without precise alignment of the hole center, meeting the needs of efficient assembly and shortening single-process time. It should be noted that in the attached example, the normal of the mounting surface 11 is shown as n.

[0067] In addition, it should be noted that the fixing structure 4 can be set to adhesive, snap fastener or other forms of fixing.

[0068] In one embodiment, please refer to Figure 3 and 7 The bracket 2 has a fixing surface 23, which is spaced apart from the mounting position 21 in a direction away from the mounting surface 11. The bracket 2 has a plurality of first through holes 23a penetrating the fixing surface 23. The mounting surface 11 is provided with a plurality of first screw holes 13a, which correspond one-to-one with the plurality of first through holes 23a. The fixing structure 4 includes a plurality of fixing screws 41, which correspond one-to-one with the plurality of fixing screws 41, the plurality of first through holes 23a and the plurality of first screw holes 13a. Each fixing screw 41 passes through the corresponding first through hole 23a and is threadedly connected to the windshield base 1 via the corresponding first screw hole 13a.

[0069] In this embodiment, the fixing surface 23 and the assembly position 21 are spaced apart, so that when the bracket 2 is installed onto the windshield base 1 via the fixing screw 41, sufficient space is reserved between the assembly position 21 and the fixing surface 23 to accommodate the environmental sensing component 5, reducing the probability of the environmental sensing component 5 colliding with the windshield base 1 during assembly. At the same time, the fixing surface 23 can stably abut against the end of the screw hole on the mounting surface 11, ensuring the connection stability between the bracket 2 and the windshield base 1, and facilitating the alignment of the first through hole 23a on the fixing surface 23 with the first screw hole 13a on the mounting surface 11, improving assembly efficiency.

[0070] It should be noted that bolt fixing offers greater removability and maintainability compared to adhesive fixing. Adhesive provides permanent fixation, requiring destructive disassembly for replacement of bracket 2 later, which can easily damage surrounding components. Bolted connections, on the other hand, allow for direct disassembly, facilitating repair and replacement of parts, and reducing maintenance costs. Furthermore, adhesive installation can easily lead to bracket 2 shifting during installation, affecting installation accuracy. Bolts, through threaded engagement and with the help of washers, can precisely fix the position of bracket 2, ensuring the installation accuracy of the environmental sensing component 5.

[0071] Furthermore, compared to clip-on fastening, bolted connections can withstand greater static and dynamic loads, reducing the probability of bracket 2 detaching. Clips are prone to elastic fatigue in high and low temperature environments, leading to a decrease in locking force; the mechanical fastening structure of bolts is unaffected by ambient temperature, resulting in more durable connection stability and adapting to the needs of the entire automotive lifecycle. It should be understood that the first through hole 23a, the first screw hole 13a, and the fixing screw 41 are each provided in two or more forms. Specifically, in this design, the first through hole 23a, the first screw hole 13a, and the fixing screw 41 are each provided in four forms.

[0072] In one embodiment, the mounting surface 11 is provided with a plurality of mounting platforms 13 protruding toward the bracket 2, and the plurality of mounting platforms 13 correspond one-to-one with a plurality of first through holes 23a, and each mounting platform 13 is provided with a first screw hole 13a.

[0073] In this embodiment, the fixing surface 23 is attached to the end face of the mounting platform 13, increasing the space between the assembly position 21 and the mounting surface 11, which facilitates the accommodation of the environmental sensing element 51. Simultaneously, the mounting platform 13 can form a stress concentration area by thickening the local structure. The threaded hole is located on the thickened mounting platform 13, increasing the thread engagement length and stress area. Compared to directly drilling and tapping holes in the thin sheet metal of the windshield base 1, this effectively disperses the pressure during bolt tightening, preventing deformation of the base sheet metal and thread stripping, thus improving connection strength and long-term reliability. Furthermore, the windshield base 1 needs to fulfill functions such as sealing and support; directly drilling holes would compromise its overall structural integrity and reduce rigidity. The independent design of the mounting platform 13 reduces structural damage to the main body of the windshield base 1.

[0074] Furthermore, the mounting platform 13 can serve as an independent positioning reference surface, allowing for individual control of its flatness and perpendicularity during machining, ensuring the precise axial direction of the threaded holes. When drilling holes directly on the windshield base 1, potential planar errors in the overall structure of the windshield base 1 can directly affect the accuracy of the threaded holes. The mounting platform 13 avoids this problem, providing a stable mounting reference for the bracket 2. It should be noted that the mounting platform 13 can be integrally formed with the windshield base 1 by stamping, while the threaded holes can be machined separately.

[0075] In one embodiment, the bracket 2 is further provided with a mating plate 25 on the fixed surface 23. The mating plate 25 protrudes from the fixed surface 23 and faces the windshield base 1, and corresponds to the hook 121; the mating hole 22a is formed in the mating plate 25.

[0076] In this embodiment, the section of the L-shaped hook 121 that connects to the windshield base 1 is defined as the connecting section, which is set at an angle to the columnar hook head 122. When the hook head 122 extends into the mating hole 22a, the connecting section can be stopped on one side of the mating plate 25, and the end face of the mating plate 25 fits and is positioned against the end face of the connecting section, reducing the swaying of the bracket 2 after pre-hanging. It should be noted that the mating plate 25 is located to the side of the assembly position 21 in the lateral direction and is offset from the assembly position 21. Moreover, the mating plate 25 is located on one side of the bracket 2 in the windshield tilt direction, specifically, the mating plate 25 is located on the upper side of the bracket 2 in the windshield tilt direction. In this way, the mating hole 22a is further located in the field of vision of the assembly personnel, improving assembly efficiency.

[0077] In one embodiment, the fixed surface 23 is further provided with two limiting grooves 24a, the extension directions of the two limiting grooves 24a intersect, and each limiting groove 24a is provided with a first through hole 23a; the mounting platform 13 corresponding to the limiting groove 24a can extend into the corresponding limiting groove 24a, and in the extension direction of each limiting groove 24a, the size of the corresponding mounting platform 13 is smaller than the size of the limiting groove 24a.

[0078] In this embodiment, the bracket 2 and the windshield base 1 are positioned in two dimensions by the cooperation of the two intersecting limiting grooves 24a extending in different directions and the corresponding mounting platform 13, forming a cross-constraint structure. This restricts the translation and offset of the bracket 2 in the plane, reduces the probability of the bracket 2 shifting due to vibration, and ensures installation accuracy. Furthermore, since the mounting platform 13 is engaged in the corresponding limiting groove 24a, the pre-tightening force after bolt tightening and the vibration load during driving are distributed to the limiting grooves 24a in both directions, making the force distribution of the bracket 2 more uniform. In addition, this solution provides a first through hole 23a in the limiting groove 24a, allowing for direct positioning using the corresponding mounting platform 13, eliminating the need for an additional limiting platform on the mounting surface 11, thus reducing costs.

[0079] Specifically, in one embodiment, the extension directions of the two limiting grooves 24a are defined as the X direction and the Y direction, respectively. The limiting groove 24a in the X direction is set in the form of an oval hole, and the limiting groove 24a in the Y direction is set in the form of an elongated hole.

[0080] In one embodiment, two first through holes 23a are provided with first protruding ribs 24 at one end of the fixed surface 23, and the extending directions of the two first protruding ribs 24 intersect and respectively form two limiting grooves 24a.

[0081] In this embodiment, a limiting groove 24a is formed by the first protruding rib 24, rather than a groove formed by recessing on the fixed surface 23. The groove formed by the first protruding rib 24 not only meets the limiting requirements in the X / Y directions, but also avoids reducing the strength of the bracket 2 by eliminating the need for slotting. Furthermore, the first protruding rib 24 increases the thickness of the corresponding part of the bracket 2, thereby increasing the strength of the bracket 2. It should be understood that in this design, the height of the first protruding rib 24 is less than the height of the mounting platform 13.

[0082] In one embodiment, the bracket 2 has an opening 21a at least at the mounting position 21 in a direction away from the windshield base 1.

[0083] In this embodiment, an opening 21a penetrating the bracket 2 is provided at the assembly position 21. On the one hand, unnecessary materials on the bracket 2 can be removed, reducing the overall weight of the bracket 2 and alleviating the load-bearing pressure on the windshield base 1 without affecting the core load-bearing strength. On the other hand, rain sensors and interior rearview mirror 81 wiring are often arranged near the windshield base 1, and the opening 21a provides clearance to prevent the bracket 2 from colliding or being squeezed with related components after installation, ensuring the normal operation of each component and avoiding assembly difficulties caused by interference. In addition, it can also enhance air circulation, assist in heat dissipation, and improve the working environment of the environmental sensing component 5. Moreover, for the stamped bracket 2, the opening 21a design can also reduce the amount of material used and reduce stress concentration during forming.

[0084] In one embodiment, the bracket 2 has a plurality of second ribs 27 on the side away from the windshield base 1, and the plurality of second ribs 27 are connected in an interlaced manner.

[0085] In this embodiment, the second rib 27, through its raised rib structure design, increases the strength of the bracket 2, resisting bending and torsional deformation caused by vibration, impact, or bolt preload during driving. This reduces the probability of warping after long-term use and ensures the installation stability of accessories such as the environmental sensing component 5. Simultaneously, the second rib 27 serves as a force transmission path, evenly distributing the load (such as accessory weight and vibration impact) borne by the bracket 2 throughout the entire bracket 2. This avoids load concentration at bolt connection points or hook 121 positions, reducing the risk of cracking due to excessive local stress.

[0086] In one embodiment, the bracket 2 has a fixing buckle 26 on at least one side of the assembly position 21 in the lateral direction, the fixing buckle 26 being used to install the wire harness clip 7.

[0087] In this embodiment, the fixing fastener 26 is positioned on one side of the assembly position 21 in the horizontal direction to reduce the impact of the wiring harness on the field of vision of the environmental sensing component 5. Simultaneously, the wiring harness clip 7 and the corresponding wiring harness are integrated onto the bracket 2, making full use of the limited space at the windshield base 1 and improving space utilization. In this design, the bracket 2 has at least one fixing fastener 26 on each side of the assembly position 21 in the horizontal direction. Specifically, the bracket 2 integrates fixing fasteners 26 for the wiring harness related to the environmental sensing component 5, as well as fixing fasteners 26 for ETC 9 (Electronic Toll Collection), specifically, fixing fasteners 26 for the ETC 9 connector wiring harness. It should be understood that a slot or hole 26a can be provided at the fixing fastener 26 for the installation of the wiring harness clip 7. In this design, a hole 26a is provided at the fixing fastener 26.

[0088] It should be noted that in the relevant technology, the lidar 52 and the camera 53 are usually fixed by a split bracket 2, which requires the lidar 52, the camera 53 and the bracket 2 to be connected by multi-level screws, resulting in the accumulation of errors during the installation process, a long dimensional chain, and ultimately affecting the spatial positioning accuracy of the sensor.

[0089] Therefore, this application also provides a vehicle, including a bracket assembly and an environmental sensing component 5; the bracket assembly is as described above, and the bracket 2 of the bracket assembly includes multiple frames, which are integrally formed and each has an assembly position 21; the environmental sensing component 5 includes multiple environmental sensing elements 51, which are respectively disposed on the multiple frames.

[0090] In this embodiment, the frame for mounting multiple environmental sensing elements 51 is integrally formed. After the multiple environmental sensing elements 51 are mounted on the bracket 2, the bracket 2 is then mounted on the windshield base 1. This shortens the installation dimension chain of the environmental sensing elements 51, eliminates the error accumulation problem of traditional separate brackets 2, and thus improves the spatial positioning accuracy of the sensors. It should be noted that in this solution, the environmental sensing elements 51 are also attached to the bracket 2 with screws.

[0091] Specifically, in this solution, multiple frames are integrally die-cast. Furthermore, the multiple environmental sensing elements 51 include at least a LiDAR 52 and a camera 53. The integrally die-cast bracket 2 integrates the mounting positions of the LiDAR 52 and the camera 53 into the same frame structure, reducing the error transmission problems caused by multi-level connections in traditional split brackets 2. The high-precision forming capability of the die-casting process ensures the dimensional stability of the bracket 2 body, while the sensors are directly attached to the same bracket 2 using screws. This direct attachment method avoids the accumulation of tolerances in intermediate connecting parts, reducing spatial positioning deviations.

[0092] Thus, through structural integration and process optimization, the accuracy problem caused by the lengthy dimensional chain is solved, improving the spatial positioning consistency of the environmental perception sensor. Simultaneously, the stiffness and strength of bracket 2 are enhanced by the die-casting process, ensuring vibration resistance during vehicle operation and reducing the probability of sensor misalignment due to external loads, thereby guaranteeing the stability of the field of view (FOV) coverage of LiDAR 52 and camera 53. Furthermore, the installation error of the environmental perception sensor is controlled within a reasonable range, improving the accuracy and reliability of the perception data and providing higher-quality input for environmental modeling and decision-making in the intelligent driving system.
