[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0036] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0037] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0038] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0041] In existing technologies, the automatic parking function in autonomous driving technology mainly relies on ultrasonic radar and cameras to perceive the environment behind the vehicle. However, these sensors have blind spots in recognizing low obstacles and pole-shaped objects, such as safety cones and thin metal poles, which may lead to collisions during parking.

[0042] In view of this, embodiments of this application provide a lidar mounting assembly and a vehicle. The design of the first bracket and the second bracket allows for adjustment of the relative position of the second bracket and the first bracket during the assembly process, which can correct the installation angle deviation of the lidar module. The multi-layer positioning of the first bracket and the second bracket also ensures the installation stability of the lidar module. In addition, the lidar module is fixed by the accommodating space formed by the first bracket and the second bracket, and with the design of the first detection hole, accurate signal transmission is achieved.

[0043] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0044] refer to Figures 2 to 11 On the one hand, this application provides a lidar mounting assembly 10 that can be used in a vehicle 20. The lidar mounting assembly 10 includes a rear bumper assembly 100, a first bracket 200, a second bracket 300, and a lidar module 500.

[0045] The first bracket 200 is connected to the rear bumper assembly 100. For example, the first bracket 200 and the rear bumper assembly 100 can be fixedly connected, such as by welding or riveting, or they can be detachably connected, such as by snap-fit ​​or bolt connection. The first bracket 200 is located on the side of the rear bumper assembly 100 facing the vehicle interior, and the first bracket 200 has a first detection hole 201. The second bracket 300 is detachably connected to the first bracket 200, and the second bracket 300 and the first bracket 200 together define an accommodating space 400, which communicates with the first detection hole 201. The lidar module 500 is located in the accommodating space 400, and the lidar module 500 is adapted to transmit and receive detection signals through the first detection hole 201.

[0046] The rear bumper assembly 100 can be the rear bumper component of the vehicle 20, and can be made of metal or composite materials. The rear bumper assembly 100 is used to support the first and second brackets 300 and protect the internal components such as the lidar module 500. The first bracket 200 is fixedly connected to the rear bumper assembly 100. Optionally, the first bracket 200 and the rear bumper assembly 100 can be connected by welding, bolts, etc. The side of the first bracket 200 facing the inside of the vehicle is provided with a detection hole, which can be used for signal penetration of the lidar module 500.

[0047] The second bracket 300 is detachably connected to the first bracket 200. Optionally, the detachable connection method can be snap-fit, screw fixing, etc. The accommodating space 400 formed by the second bracket 300 and the first bracket 200 can be used to accommodate the lidar module 500.

[0048] Optionally, the lidar module 500 can be a DTOF (Direct Time-of-Flight) lidar module, an ITOF (Indirect Time-of-Flight) lidar module, or other types of lidar; this application does not impose any restrictions on this. The following description uses a DTOF lidar module 500 as an example.

[0049] DTOF lidar modules can employ both DTOF principles and DTOF imaging. The DTOF principle is a method for calculating distance by directly measuring the time difference between the emission and reception of a laser pulse. Specifically, a DTOF lidar module 500 may include a laser emitter and a detector. The laser emitter emits short-pulse laser light, which is reflected by the target object and received by the detector. By measuring the round-trip time difference (Δt) of the light pulse, the distance to the target object is calculated using the formula d = cΔt / 2 (where c is the speed of light).

[0050] DTOF imaging systems can be based on DTOF ranging technology. A laser emitter emits multiple laser pulse signals, and a detector uses a photosensitive pixel array (such as a SPAD pixel array) to collect the pulse signals reflected back by the target object. The time intervals between the emission and return of multiple pulse signals are counted to form histogram data. The time of flight value is then determined based on the histogram data to calculate the depth information of the target object, thereby achieving three-dimensional imaging.

[0051] It is evident that the DTOF principle of the DTOF lidar module is the core of "direct time measurement and distance calculation." DTOF imaging is the process of converting distance data into a three-dimensional image through "scanning sampling + point cloud integration." The combined design of the DTOF principle and DTOF imaging enables the DTOF lidar module 500 to possess high-precision, interference-resistant three-dimensional perception capabilities, thereby improving the detection and imaging capabilities of vehicles 20.

[0052] The lidar module 500 may include a detection unit 520, which may be embedded in the first detection hole 201 to ensure that the signal transmission direction is aligned with the axis of the first detection hole 201.

[0053] Specifically, the first bracket 200 can be fixed to the inside of the rear bumper assembly 100, and its detection hole diameter can be slightly larger than the outer diameter of the lidar module detection section 520. The lidar module 500 can be finely adjusted in angle during installation. The second bracket 300 can be connected to the first bracket 200 by screws, and the gap between the two can be controlled by adjusting the tightness of the screws, thereby correcting the installation position angle of the lidar module 500.

[0054] The accommodating space 400 can form a closed or semi-closed cavity to reduce the impact of external light and electromagnetic interference on the signal reception of the lidar module 500. The detection signal of the lidar module can be emitted outward through the first detection hole 201, and the reflected signal returns through the first detection hole 201 after encountering an obstacle, achieving high-precision ranging.

[0055] As can be seen, by setting up the lidar module 500, the lidar mounting assembly 10 possesses high-precision, interference-resistant three-dimensional perception capabilities, improving obstacle recognition accuracy and reducing automatic parking accidents. In addition, the design of the first bracket 200 and the second bracket 300 allows for adjustment of the relative position of the second bracket 300 and the first bracket 200 during assembly, which can correct the installation angle deviation of the lidar module 500. The multi-layer positioning of the first bracket 200 and the second bracket 300 also ensures the installation stability of the lidar module 500. Furthermore, the lidar module 500 is fixed by the receiving space 400 formed by the first bracket 200 and the second bracket 300, and in conjunction with the design of the first detection hole 201, accurate signal transmission is achieved.

[0056] In some implementations, reference Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 The first bracket 200 and the second bracket 300 are arranged sequentially from back to front along the front-rear direction of the vehicle 20. The lidar module 500 is located between the first bracket 200 and the second bracket 300, and the lidar module 500 is in a limiting fit with the first bracket 200.

[0057] The longitudinal direction of the vehicle 20 can be the longitudinal axis from the front to the rear of the vehicle. Therefore, the first bracket 200 and the second bracket 300 can be arranged sequentially along the longitudinal axis. The lidar module 500 is located between the first bracket 200 and the second bracket 300 and is limited and matched with the first bracket 200, that is, a mechanical constraint relationship is formed between the lidar module 500 and the first bracket 200.

[0058] The lidar module 500 is positioned in a limiting fit with the first bracket 200. Optionally, the limiting fit can be achieved by using a snap-fit, boss and groove interlocking structure to ensure the installation stability of the lidar module 500 and prevent the lidar module 500 from shifting during the movement of the vehicle 20.

[0059] Understandably, the first bracket 200 serves as an intermediate connector between the rear bumper assembly 100 and the second bracket 300, and its arrangement along the front-rear direction of the vehicle 20 forms a stable mounting base. The lidar module 500 is clamped between the first bracket 200 and the second bracket 300, and the limiting fit between the lidar module 500 and the first bracket 200 eliminates assembly gaps.

[0060] When the rear bumper assembly 100 is subjected to external impact, the lidar module 500 can form multi-point constraints with the first bracket 200 through the limiting structure 211, avoiding detection signal offset caused by bracket deformation. The second bracket 300 can cover the lidar module 500 through a detachable connection to form a receiving space 400. The detachable connection between the second bracket 300 and the first bracket 200 also allows for quick disassembly during maintenance.

[0061] By clamping the first bracket 200 and the second bracket 300 from the front and rear, and with the limiting structure 211 between the lidar module 500 and the first bracket 200, the lidar module 500 is given multi-directional constraints in space, which improves its impact resistance, reduces the possible displacement risk of the lidar module 500 during the movement of the vehicle 20, and ensures that the detection signal transmission axis is consistent with the preset direction.

[0062] In some implementations, reference Figure 3 , Figure 4 , Figures 7 to 11 The first bracket 200 includes a first mounting part 210 and a first fixing part 220 located around the first mounting part 210. The first fixing part 220 is welded to the rear bumper assembly 100. The first mounting part 210 has a first detection hole 201. The first mounting part 210 also has a plurality of limiting structures 211 surrounding the first detection hole 201. The plurality of limiting structures 211 are spaced apart from the first detection hole 201 and together enclose the mounting area 230.

[0063] The lidar module 500 includes a module body 510 and a detection unit 520. The detection unit 520 is located on the side of the module body 510 facing the first bracket 200. The detection unit 520 is embedded in the first detection hole 201. The module body 510 is snapped into the installation area 230.

[0064] The first mounting part 210 can be a main structure that supports the first detection hole 201 and the limiting structure 211. The first mounting part 210 can form the first detection hole 201 by a stamping process. The limiting structure 211 can be a protrusion or recess used to constrain the position of the module body 510. Specifically, it can be implemented by a bent edge or boss formed by stamping. Multiple limiting structures 211 can form a circumferential limit on the module body 510.

[0065] The mounting area 230 can be a spatial area enclosed by the limiting structure 211, which prevents the module body 510 from radially shifting after being embedded in the mounting area 230. The detection unit 520 can be the signal transceiver unit of the lidar module 500. Optionally, the signal transceiver unit can be implemented with an integrated optical lens structure, and its outer diameter can form an interference fit with the diameter of the first detection hole 201.

[0066] Specifically, the first bracket 200 can be fixed to the rear bumper assembly 100 by welding, and the first detection hole 201 opened on its first mounting part 210 can be used to accommodate the detection part 520 of the lidar module 500. Multiple limiting structures 211 can be distributed around the detection hole to form a ring-shaped arrangement of limiting points, and the multiple limiting points can maintain a distance from the first detection hole 201 to avoid interference with signal transmission.

[0067] The mounting area 230 is confined within the area enclosed by the limiting structure 211. The module body 510 can be embedded into the mounting area 230 by snap-fit, and the limiting structure 211 can form multi-point contact constraints on the module body 510. After the detection unit 520 passes through the first detection hole 201, its outer surface can be tightly fitted with the inner wall of the first detection hole 201 to ensure the accuracy of the signal transmission direction.

[0068] Through the cooperation of multiple limiting structures 211 and the installation area 230, the module body 510 can achieve automatic positioning during assembly, and accurate installation can be achieved without manual calibration, ensuring assembly efficiency. In addition, the embedded design of the detection unit 520 and the first detection hole 201 can reduce the risk of signal deviation caused by vibration, and ensure the stability of the signal transmission and reception direction, thereby improving the obstacle recognition accuracy of the automatic parking system.

[0069] In some implementations, reference Figures 5 to 7 , Figure 10 and Figure 11 At least one positioning structure 530 is provided on the side of the lidar module 500 facing the second bracket 300. The second bracket 300 includes a positioning engagement structure 310, and the positioning structure 530 and the positioning engagement structure 310 are positioned and engaged.

[0070] The positioning structure 530 can be a protrusion or embedded component used to fix the position, specifically a column, boss, etc., to limit the relative displacement between the lidar module 500 and the second bracket 300. The positioning mating structure 310 can be a groove, hole, etc., that complements the shape of the positioning structure 530, specifically through holes, blind holes, etc., to achieve rapid alignment and fixation of the lidar module 500 and the second bracket 300 through mechanical fitting.

[0071] Specifically, when the lidar module 500 is installed within the receiving space 400 formed by the first bracket 200 and the second bracket 300, the positioning structure 530 can engage with the positioning mating structure 310, such as by inserting the positioning post 531 into the positioning hole 311. This allows the lidar module 500 to be initially positioned without the need for additional tools during installation. After positioning is complete, the lidar module 500 can be further secured using fasteners.

[0072] Thus, by setting up the positioning structure 530 and the positioning matching structure 310, the lidar module 500 is quickly and accurately aligned during installation, reducing manual adjustment time and improving installation efficiency. In addition, it enhances the structural stability of the lidar module 500 in the vibration environment of the vehicle 20, ensuring signal transmission and reception stability.

[0073] In some implementations, reference Figures 5 to 7 , Figure 10 and Figure 11 The positioning structure 530 is formed as a positioning post 531, and the positioning mating structure 310 is formed as a positioning hole 311.

[0074] Optionally, the inner diameter of the positioning hole 311 may be 0.1 mm to 0.3 mm larger than the outer diameter of the positioning post 531.

[0075] Optionally, the lidar module 500 may also include an electrical connection module 540, and the second bracket 300 may have a clearance hole 321 for accommodating the electrical connection module 540, which may communicate with a through hole.

[0076] Optionally, two positioning posts 531 and two positioning holes 311 can be provided respectively, and the two positioning posts 531 and two positioning holes 311 can simultaneously realize the rapid positioning of the lidar module 500.

[0077] Thus, during the installation of the lidar module 500, the positioning post 531 can be inserted into the corresponding positioning hole 311, which can complete the rapid pre-positioning of the lidar module 500 before the fasteners are tightened, reducing the repeated calibration operations during the assembly process and improving the assembly efficiency of the lidar module 500 and the second bracket 300.

[0078] In some implementations, reference Figures 5 to 8 , Figure 10 , Figure 11 The lidar module 500 also includes two electrical connection modules 540. The two electrical connection modules 540 are located on the side of the module body 510 facing the second bracket 300. The second bracket 300 includes a second mounting part 320 and a second fixing part 330 located around the second mounting part 320. The second mounting part 320 is provided with two clearance holes 321. The clearance holes 321 correspond one-to-one with the electrical connection modules 540. The electrical connection modules 540 pass through the corresponding clearance holes 321. There are two positioning holes 311. One positioning hole 311 is located at the edge of the clearance hole 321 and communicates with the clearance hole 321. The other positioning hole 311 is located between the two clearance holes 321.

[0079] The electrical connection module 540 serves as an interface component for connecting the lidar module 500 to external circuits, providing a stable power supply and data transmission channel for the lidar module 500. The clearance hole 321 is an opening structure on the second bracket 300 for inserting the power supply connection module 540, providing physical space for the electrical connection module 540 to avoid assembly interference.

[0080] Specifically, two electrical connection modules 540 can be arranged on the surface of the module body 510 that contacts the second bracket 300. The two clearance holes 321 of the second bracket 300 correspond to the positions of the electrical connection modules 540, so that the electrical connection modules 540 can pass through the clearance holes 321 for easy connection with external wiring harnesses.

[0081] Of the two positioning holes 311, one positioning hole 311 is connected to the edge of one of the clearance holes 321, and the other positioning hole 311 is located between the two clearance holes 321. This layout design allows the positioning post 531 to cooperate with the positioning hole 311 to simultaneously constrain the lateral and longitudinal positions of the electrical connection module 540.

[0082] During assembly, the electrical connection module 540 passes through the clearance hole 321, and the positioning post 531 inserts into its corresponding positioning hole 311, enabling rapid positioning of the lidar module 500 in space. The coordinated design of the clearance hole 321 and the positioning hole 311 ensures that the electrical connection module 540 remains in its predetermined position throughout the assembly process, avoiding potential contact failures due to vibration or assembly errors.

[0083] Optionally, the second fixing part 330 may also be connected to a lead plate 350, on which a lead hole 351 is provided, through which a wire harness connected to the lidar module 500 can pass.

[0084] In some implementations, reference Figure 6 , Figure 7 and Figure 10 The module body 510 is provided with multiple connection holes 511 on the side facing the second bracket 300. The second bracket 300 is provided with multiple fixing holes 340 corresponding to the connection holes 511. The module body 510 and the second bracket 300 are connected by fasteners passing through the fixing holes 340 and the connection holes 511.

[0085] The connecting hole 511 can be a circular through hole, a threaded hole, or the like, used to align with the fixing hole 340 of the second bracket 300 and be fixed by fasteners. The fixing hole 340 can be a hole structure on the second bracket 300 corresponding to the position of the connecting hole 511, ensuring that the fastener can pass through smoothly and complete the connection.

[0086] Fasteners can be bolts, screws or rivets. For example, fasteners can be hexagonal head screws, self-tapping screws, etc., which fasten the module body 510 and the second bracket 300 together by passing through the fixing hole 340 and the connecting hole 511.

[0087] Specifically, the module body 510 has multiple pre-machined connecting holes 511 on the side facing the second bracket 300, and the second bracket 300 has the same number and position of fixing holes 340. During installation, the module body 510 is aligned with the second bracket 300 so that the connecting holes 511 and fixing holes 340 completely overlap, and then fasteners are inserted and tightened to achieve a rigid connection between the module body 510 and the second bracket 300.

[0088] The detachable connection is achieved through the cooperation of the connecting hole 511, the fixing hole 340 and the fastener, which facilitates later maintenance or replacement. This connection method also ensures that there is no relative displacement between the module body 510 and the second bracket 300, avoiding the risk of misalignment caused by vibration or external force, ensuring the positioning accuracy of the module body 510 and the bracket, thereby improving the accuracy of rear obstacle recognition, and also ensuring the stability of the lidar module 500 during the driving of the vehicle 20.

[0089] In some implementations, reference Figures 4 to 6 , Figure 9 The first fixing part 220 is provided with a first mounting hole 221, and the second fixing part 330 is provided with a second mounting hole 331. The first fixing part 220 and the second fixing part 330 are connected by fasteners passing through the first mounting hole 221 and the second mounting hole 331.

[0090] The first mounting hole 221 and the second mounting hole 331 can be through holes respectively provided on the first fixing part 220 and the second fixing part 330. They can be round holes of equal diameter or countersunk holes with threads. Fasteners such as bolts can be fastened by passing through the first mounting hole 221 and the second mounting hole 331.

[0091] First, align the second mounting hole 331 of the second fixing part 330 with the first mounting hole 221 of the first fixing part 220, insert the bolt and tighten the nut to make the first bracket 200 and the second bracket 300 rigidly connected, thereby realizing the rapid assembly and precise positioning of the first bracket 200 and the second bracket 300, and thus ensuring the installation stability of the lidar module 500.

[0092] In some implementations, reference Figure 4 The first fixing part 220 is welded to the rear bumper assembly 100.

[0093] During the welding process, the rear bumper assembly 100 and the first fixing part 220 can be fixed by welding to form a continuous connection interface. As the materials of the two are fused after welding, the relative position of the first bracket 200 and the rear bumper assembly 100 is precisely fixed, avoiding bracket displacement due to assembly errors or long-term use, thereby ensuring that the detection part 520 of the lidar module 500 and the first detection hole 201 always remain aligned.

[0094] The first bracket 200 is rigidly connected to the rear bumper assembly 100 by welding, ensuring that the lidar module 500 always maintains the preset position during the driving of the vehicle 20, thereby improving the recognition accuracy of rear obstacles.
