[0152] Next, a second embodiment of the present invention will be described. The same parts and configurations as those of the first embodiment are assigned the same reference numerals, and description thereof will be omitted. Here, only the differences from the first embodiment will be described.

[0153] In this embodiment, the front edges of the upper casing surface 4 and the lower casing surface 5 are arc-shaped (for example, semicircular arc-shaped), and the front edges of the upper casing surface 4 and the front edge of the lower casing surface 5 are formed along the front-rear direction. The same position and the same arc shape, so that the arc surface sandwiched between the front edge of the upper shell surface 4 and the front edge of the lower shell surface 5 is perpendicular to the upper shell surface 4 and the lower shell surface 5 . When the lidar is mounted horizontally, it can also be referred to as perpendicular to the horizontal. The arcuate (curved surface) ...

Abstract

The invention discloses a laser radar. The radar comprises a main housing which is provided with a front space for accommodating a laser transmitting assembly and a laser receiving assembly, and a rear space for configuring a circuit board, a rear housing attached to the main housing so as to cover the rear space, and a front window attached to the main housing so as to cover the front space, the main housing has a rear housing attachment opening which is in engagement with the rear housing, the rear housing attachment opening is located in a plane inclined in a front-rear direction with respect to a horizontal direction, and the rear housing has a wedge-shaped or triangular shape when viewed from a side surface. According to the invention, integration, miniaturization and large field of view of the laser radar can be realized. In addition, the laser radar can perform scanning and detection in a large range, and excellent sealing characteristics and heat dissipation characteristics of the laser radar can be realized.

Description

technical field [0001] The invention relates to a laser radar, in particular to a laser radar mounted on a vehicle. Background technique [0002] Lidar is a device that measures the distance, speed and other parameters of the target object by sending a laser to the surface of the object, and then measuring the arrival time of the reflected beam. It is a device that integrates optical devices, mechanical structures, electrical and software controls. Integrated optical instrument. With the development of technologies such as autonomous driving, there are more and more scenarios where lidar is integrated and installed in vehicles. [0003] For example, when the laser radar is installed on a vehicle, etc., it is hoped that the laser radar can meet the requirements of integration, miniaturization, large field of view, light weight, convenient and reliable installation, and low cost. [0004] Existing products mostly adopt the manufacturing method of overall debugging and assemb...
