Description

The present disclosure claims priority to Chinese Patent Application No. 202322053784.1, filed on July 31, 2023 and entitled "DETECTION ASSEMBLY MOUNTING STRUCTURE AND VEHICLE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD The present disclosure relates to the field of vehicle technologies, and in particular, to a detection assembly mounting structure and a vehicle. BACKGROUND A detection assembly (for example, a lidar) on a vehicle roof is one of important functional parts of an autonomous driving system. To ensure function implementation of the detection assembly, mounting and positioning of the detection assembly in a vehicle coordinate system are required to meet high mounting precision and long-term connection reliability. In addition, the detection assembly is also one of appearance parts, and the detection assembly and a trim panel for the detection assembly are further required to meet specific appearance matching precision. To meet the first requirement, the detection assembly on the vehicle roof needs to be connected to a vehicle roof bow. To meet the second requirement, the detection assembly also needs to be connected to the trim panel. The trim panel is fastened to the vehicle roof bow. If the detection assembly is connected to both the vehicle roof bow and the trim panel, the detection assembly is over-constrained. However, because there is an error in manufacturing, mounting, and another process of the vehicle roof bow and the trim panel, a relative location relationship between the vehicle roof bow and the trim panel is not fixed, causing the trim panel and the vehicle roof bow to pull the detection assembly when the detection assembly is mounted. As a result, a posture of the detection assembly is poor, and appearance matching precision between the detection assembly and the trim panel is poor. SUMMARY The present disclosure provides a detection assembly mounting structure and a vehicle. A detection assembly of the detection assembly mounting structure is connected to a trim panel, and the detection assembly is connected to a vehicle roof bow via a tolerance adjuster. Technical solutions of the detection assembly mounting structure and the vehicle are described below. According to a first aspect, the present disclosure provides a detection assembly mounting structure. The detection assembly mounting structure includes a vehicle roof bow, a trim panel, a detection assembly, and a tolerance adjuster. The trim panel is connected to the vehicle roof bow, the detection assembly is connected to the trim panel, and the detection assembly is connected to the vehicle roof bow via the tolerance adjuster. The detection assembly may be a lidar assembly, and the trim panel may be a lidar trim panel. The tolerance adjuster may also be referred to as an adaptive nut. According to the technical solution provided in the present disclosure, when the detection assembly is mounted, the detection assembly is first connected to the trim panel, and then the trim panel is connected to the vehicle roof bow. In this case, the detection assembly has been positioned, but is not directly connected to the vehicle roof bow. Due to a manufacturing error and the like, a relative location relationship between the detection assembly and the vehicle roof bow may not be a designed value. For example, a height of mounting space between the detection assembly and the vehicle roof bow may not be a specified value. However, because the tolerance adjuster can adapt to a height change of the mounting space within a specific range, in the present disclosure, the detection assembly is connected to the vehicle roof bow via the tolerance adjuster, to adapt to a deviation between the detection assembly and the vehicle roof bow. In a mounting process, the detection assembly is not pulled, so that a posture of the detection assembly and appearance matching precision between the detection assembly and the trim panel are both in a good state. In a possible implementation, the tolerance adjuster includes an outer tube and an inner tube. The outer tube is in threaded connection to the inner tube, and the outer tube and the inner tube are located between the detection assembly and the vehicle roof bow. The detection assembly mounting structure further includes a bolt (or a screw). The bolt passes through the vehicle roof bow, the inner tube, and the outer tube, and is in threaded connection to the detection assembly. The outer tube and the inner tube are located in the mounting space between the detection assembly and the vehicle roof bow, and are configured to support the detection assembly, to prevent the detection assembly from moving toward the vehicle roof bow. In addition, when the inner tube rotates relative to the outer tube, a total length of the inner tube and the outer tube changes, so that the tolerance adjuster can adapt to mounting space of different heights. After the bolt passes through the vehicle
