Description

Technical Field

[0001] This application relates to the field of vehicle component fastening technology, and more particularly to a lidar mount for a vehicle and the vehicle itself. Background Technology

[0002] Currently, during the final assembly of automobiles, the radar assembly is fixedly connected to the surface of the vehicle's roof assembly. However, during the vehicle assembly phase, after the LiDAR is pre-assembled with the trim panels, it is installed on the vehicle at the final assembly station. The entire installation process is manual. Because the installation location is on the roof, the operator needs to bend over, look up from inside the vehicle, and tighten the bolts by holding a fastening gun and aligning it with the bolt holes. This makes it difficult to keep the operator still at this station, compromising assembly consistency and increasing the risk of the fastening gun hitting at an angle, causing stripping. Furthermore, since the entire radar base is made of a single die-cast aluminum component with poor ductility and high brittleness, when the aforementioned angled hitting leads to stripping, the bolt holes penetrating the radar base are easily damaged by the high-strength fastening bolts, rendering the bolt holes unusable. The material properties of die-cast aluminum also prevent secondary repairs of stripped bolt holes, leading to production line shutdowns, vehicle rework, removal of the LiDAR trim panels, radar removal, radar replacement, and then queuing for a second run, impacting production line efficiency. Utility Model Content

[0003] This application provides a lidar base and vehicle for use in vehicles, which reduces bolt hole damage caused by stripped threads, lowers the rework rate, and improves production line efficiency.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include: Firstly, the lidar base includes a base body and a connector. The base body has a mounting foot on its side, and the mounting foot has a through hole extending through the mounting foot along a first direction X. One end of the connector has a bolt hole extending along the first direction X. The end of the connector with the bolt hole is detachably connected to the mounting foot, and the bolt hole is opposite to the through hole.

[0005] This application proposes a lidar base for vehicles. The base body overlaps the surface of the vehicle roof sheet metal. Fastening bolts are passed through the vehicle roof sheet metal and inserted into bolt holes in the connector, so that the fastening bolts and bolt holes are fixed by threaded engagement. Since the base body and the connector are relatively independent components, their materials may be different. However, when fastening bolts and bolt holes of the same material come into contact, their strength is consistent. Even if the bolts are driven at an angle due to worker error, they will not cause serious damage to the bolt holes or the threads of the fastening bolts, thereby reducing the overall vehicle repair rate and improving production line efficiency.

[0006] It is understandable that by setting the connector and the base body as independent components, the base body can still use conventional die-cast aluminum parts, while the connector uses low-carbon steel, thereby ensuring that the original purchased materials and production lines remain unchanged. Since both the connector and the fastening bolts are made of low-carbon steel, the strength matching between the bolt holes and the fastening bolts is achieved. Furthermore, this material is a conventional choice for fastening bolts by those skilled in the art.

[0007] Optionally, the outer peripheral wall of the connector is provided with an annular flange, and the end face of the flange abuts against the surface of the mounting foot.

[0008] Optionally, the flange surface facing the mounting foot has a waterproof structure protruding towards the mounting foot, and the mounting foot surface has a groove matching the shape of the waterproof structure. The waterproof structure is embedded in the groove and fixedly connected to the groove.

[0009] Optionally, the waterproof structure includes a plurality of protrusions arranged around the outer periphery of the connector.

[0010] Alternatively, when viewed from the first direction X, the protrusion is obliquely toothed.

[0011] Optionally, the waterproof structure further includes a convex ring disposed along the outer periphery of the connector, and a plurality of the convex protrusions are disposed around the outer periphery of the convex ring.

[0012] Optionally, the surface of the waterproof structure is provided with a waterproof coating, which is cured on the surface of the waterproof structure.

[0013] Optionally, the end of the connector that is connected to the mounting foot is provided with a connecting part, which is embedded in the through hole and fixedly connected to the inner wall of the through hole.

[0014] Secondly, embodiments of this application provide a vehicle including a body, a lidar base according to the first aspect of this application, and fastening bolts. The fastening bolts pass through the roof sheet metal, and the through hole connects to the bolt hole. The vehicle proposed in this application embodiment reduces bolt hole damage caused by stripped threads to at least a certain extent, lowers the rework rate, and improves production line efficiency.

[0015] Optionally, the surface of the mounting foot away from the connector abuts against the roof sheet metal. Attached Figure Description

[0025] Reference Figure 1 and Figure 2 This utility model embodiment provides a lidar base including a base body 100 and a connector 200. The base body 100 has mounting feet 110 on its side. (Refer to...) Figure 3 The mounting foot 110 has a through hole 111 extending through the mounting foot 110 along the first direction X; one end of the connector 200 has a bolt hole 210 extending along the first direction X, and the end of the connector 200 with the bolt hole 210 is detachably connected to the mounting foot 110, with the bolt hole 210 and the through hole 111 being opposite in position. Specifically, the lidar base is used in a vehicle, which also includes a body and fastening bolts, with the fastening bolts passing through the roof sheet metal of the body and connecting the through hole 111 and the bolt hole 210.

[0026] During vehicle assembly, the lidar base is mounted to the roof sheet metal using fastening bolts. Specifically, the fastening bolts pass through the roof sheet metal (not shown in the figure), sequentially through the opening on the roof sheet metal and the through hole 111 on the mounting foot 110, and finally screw into the bolt hole 210 of the connector 200 to achieve threaded engagement and fixation. In actual installation, the connector 200 is first fixed to the mounting foot 110 of the base body, ensuring that the bolt hole 210 and the through hole 111 are aligned along the first direction X. Only then are the fastening bolts passed through the through hole 111 and into the bolt hole 210 to complete the threaded connection. Preferably, there are multiple mounting feet 110, distributed on both sides of the base body 100, so that both opposite sides of the base body 100 can be mounted and fixed.

[0027] It should be emphasized that by setting the connector 200 and the base body 100 as independent components, the base body 100 can still use conventional die-cast aluminum parts, while the connector 200 uses low-carbon steel, thereby ensuring that the original purchased materials and production lines remain unchanged. Both the connector 200 and the fastening bolts are made of low-carbon steel to achieve strength matching between the bolt hole 210 and the fastening bolt. Furthermore, this material is a conventional choice for fastening bolts by those skilled in the art.

[0028] As a supplement to the above, metal parts (connector 200 and fastening bolt) of the same material have similar mechanical properties (rigidity and toughness), which makes the deformation and wear behavior of connector 200 and fastening bolt consistent when subjected to force, avoiding stress concentration and local failure, and extending service life.

[0029] In summary, the base body 100 of the lidar base overlaps the surface of the vehicle roof sheet metal. The fastening bolts pass through the vehicle roof sheet metal and are inserted into the bolt holes 210 in the connector 200, so that the fastening bolts and bolt holes 210 are fixed by threaded engagement. Since the base body 100 and the connector 200 are relatively independent components, their materials may be different. However, when the fastening bolts and bolt holes 210 of the same material come into contact, their strength is consistent. The oblique insertion caused by worker construction errors will not cause serious damage to the bolt holes 210 or the threads of the fastening bolts. This reduces thread damage and component replacement caused by installation errors, lowers the frequency and cost of rework, and improves the overall efficiency of the production line and the product yield.

[0030] Optionally, the surface of the mounting foot 110 away from the connector 200 abuts against the roof sheet metal. When the lidar base is placed on the roof, the lower surface of the mounting foot 110 directly contacts the outer surface of the roof sheet metal, forming a surface-to-surface fit. After the fastening bolts are tightened, the bolt heads apply pressure to the inner surface of the roof sheet metal, and the roof sheet metal is clamped between the bolt heads and the mounting foot 110. The contact surfaces of the mounting foot 110 and the roof sheet metal maintain tight contact under pressure, which can improve the waterproof effect between the mounting foot 110 and the roof sheet metal, prevent moisture from seeping in from between the mounting foot 110 and the roof sheet metal, and improve the waterproofing of the installation area.

[0031] Optionally, refer to Figure 1 and Figure 4 The connector 200 has an annular flange 220 on its outer peripheral wall, and the end face of the flange 220 abuts against the surface of the mounting foot 110. When the connector 200 is installed onto the mounting foot 110, the end face of the flange 220 directly presses against the surface of the mounting foot 110, forming a surface contact. During the tightening of the bolts, the flange 220 provides additional support to prevent the connector 200 from shifting. At the same time, the fit between the end face of the flange 220 and the surface of the mounting foot 110 improves the waterproof effect.

[0032] Optionally, refer to Figure 2 The flange 220 has a waterproof structure 230 protruding towards the mounting foot 110 on its surface facing the mounting foot 110. The mounting foot 110 has a groove 112 that matches the shape of the waterproof structure 230. The waterproof structure 230 is embedded in the groove 112 and fixedly connected to it. When the connector 200 is assembled with the mounting foot 110, the waterproof structure 230 on the surface of the flange 220 aligns with the groove 112 on the surface of the mounting foot 110. During the axial tightening process of the fastening bolts, the waterproof structure 230 is pressed into the groove 112. The contact surfaces of the waterproof structure 230 and the groove 112 are tightly fitted under pressure, forming a physical fit and fixation. The fit between the waterproof structure 230 and the groove 112 forms a waterproof physical structure at the joint surface between the connector 200 and the mounting foot 110, preventing external moisture from seeping in through the mating gap and improving the waterproof reliability of the lidar base at the roof mounting position.

[0033] Preferably, refer to Figure 4 The waterproof structure 230 includes multiple protrusions 231 arranged around the outer periphery of the connector 200. The multiple protrusions 231 are evenly distributed along the outer periphery of the connector 200. During assembly and pressing, each protrusion 231 is embedded into the corresponding recessed area within the groove 112. The contact surface between each protrusion 231 and the groove 112 forms an independent sealing unit. The multiple protrusions 231 form a circumferentially distributed sealing structure, which also enhances the torsional load resistance between the connector 200 and the mounting foot 110, preventing relative rotation of the connector 200 within the through hole 111.

[0034] Optionally, refer to Figure 4 Viewed from the first direction X, the protrusion 231 is obliquely toothed. When the connector 200 is pressed into the groove 112 of the mounting foot 110, the inclined surface of the obliquely toothed protrusion 231 contacts the inner wall of the groove 112 and generates a guiding effect, guiding the protrusion 231 to slide smoothly into the groove 112. At the same time, the tooth tip and tooth root of the protrusion 231 are embedded into the corresponding position of the groove 112 under the action of axial pressure, forming a mechanical engagement in the oblique direction. The oblique tooth shape generates a radial component force after being pressed, making the connection between the connector 200 and the mounting foot 110 tighter. At the same time, the oblique tooth structure increases the path length and difficulty of water penetration along the joint surface, improving the sealing effect.

[0035] Preferably, refer to Figure 4 The waterproof structure 230 also includes a raised ring 232 disposed along the outer periphery of the connector 200, and a plurality of protrusions 231 disposed around the outer periphery of the raised ring 232. The raised ring 232 serves as the machining base for the protrusions 231. During actual assembly, the raised ring 232 provides the main axial support, while the protrusions 231 provide enhanced sealing and anti-rotation functions. The raised ring 232 can disperse the pressure from the protrusions 231, effectively improving the ability to resist circumferential rotation.

[0036] Optionally, as a further optimization of the above-mentioned waterproof structure 230 to further improve the waterproof effect, the surface of the waterproof structure 230 is provided with a waterproof coating (not shown in the figure), and the waterproof coating is cured on the surface of the waterproof structure 230.

[0037] Optionally, refer to Figure 2 The connector 200 has a connecting portion 240 at one end connected to the mounting foot 110. The connecting portion 240 is embedded in the through hole 111 and fixedly connected to the inner wall of the through hole 111. The connecting portion 240, as an extension of one end of the connector 200, forms an interference fit with the through hole 111, so that the connecting portion 240 and the through hole 111 fit tightly together. Specifically, when assembling the connector 200 to the base body 100, the connecting portion 240 can be first embedded in the through hole 111, and then the connecting portion 240 and the through hole 111 can be connected by a riveting process. At the same time, the waterproof structure 230 can also be pressed into the mounting foot 110 by the riveting process, so that the end face of the flange 220 directly presses against the surface of the mounting foot 110.

[0038] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
