[0034] Specifically, the connecting column 700 is arranged to connect the substrate 200 and the shell 100, so that a certain gap is left between the substrate 200 and the shell 100. The substrate 200 is installed on the connecting column 700, which can effectively fix the substrate 200 and also has a certain protection effect, preventing the shell 100 from being directly impacted on the substrate 200.

[0044] There are two LoRa power modules 500, which are respectively located on the left and right sides of the substrate 200.

[0045] Specifically, placing the LORA power modules 500 on both sides of the substrate 200 can help balance the weight and prevent the laser rangefinder receiver from tilting due to weight imbalance, which could lead to reception errors.

[0046] The working principle of the utility model is: in the utility model, laser ranging receiver is equipped with solar panel 300, the role of solar panel 300 is to convert solar energy into electric energy.Laser ranging receiver has a storage battery 400 inside, for storing the electric power generated by solar panel 300.Solar panel 300 and storage battery 400 are electrically connected, so as to transmit the generated electric energy to storage battery 400 in time.Laser sensor 600 is installed on substrate 200, and one end thereof is fixedly connected with substrate 200, and the other end thereof extends to the outside to perform ranging operation.When laser sensor 600 emits laser beam and the signal reflected back from target object, laser sensor 600 transmits the detected signal to substrate 200.
