Description

Technical Field

[0001] This utility model relates to the field of vehicle testing equipment technology, specifically to a sound level meter bracket for detecting automobile noise. Background Technology

[0002] A sound level meter is an electronic instrument used to measure sound intensity and is widely used in environmental noise monitoring, industrial safety, architectural acoustics, occupational health and other fields.

[0003] The shortcomings of existing technology:

[0004] Currently, most brackets use an interference fit between the slot and the bracket. While this allows for quick installation, it carries the risk of detachment due to external forces and lacks auxiliary locking devices, resulting in insufficient stability. Slot-type brackets require manual adjustment of the bracket position to achieve angle changes, which is time-consuming and difficult to accurately align with standard measurement directions, making it difficult to meet the needs of rapid on-site adjustment. Differences in the expansion coefficient of the bracket materials may cause deformation of the fixing structure, indirectly affecting the stability of the microphone. Utility Model Content

[0005] The purpose of this invention is to provide a sound level meter bracket for detecting automobile noise, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sound level meter bracket for detecting automobile noise, comprising a support component and a fixed placement component, wherein the fixed placement component is installed on the top of the support component, the support component is used to support the fixed placement component, and the fixed placement component is used to install the sound level meter.

[0007] Preferably, the support component includes:

[0008] Telescopic support rod, the telescopic support rod being used to adjust the overall height;

[0009] Four support legs are installed around the telescopic support rod at equal intervals. The four support legs and the telescopic support rod are designed to adapt to a wider range of terrains and sites.

[0010] Preferably, the fixed placement component includes:

[0011] A channel-shaped frame, which is installed on the top of the telescopic support rod;

[0012] A sound level meter bracket is mounted on the slotted frame and is used to mount a sound level meter.

[0013] A laser rangefinder bracket is mounted on the slotted frame and is used to mount a laser rangefinder.

[0014] Preferably, the sound level meter bracket and the laser rangefinder bracket are movably mounted on the slotted frame via a knob, the knob being mounted on the slotted frame and controlling the height and orientation of the sound level meter and the laser rangefinder.

[0015] Preferably, the overall height of the support component and the fixed placement component is less than or equal to 1.5m.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. A sound level meter bracket for detecting vehicle noise includes a fixed placement assembly comprising a slotted frame, a sound level meter bracket, and a laser rangefinder bracket. The slotted frame is mounted on the top of a telescopic support rod. The sound level meter bracket is mounted on the slotted frame and is used to mount the sound level meter. The laser rangefinder bracket is mounted on the slotted frame and is used to mount the laser rangefinder. The sound level meter bracket and the laser rangefinder bracket are movably mounted on the slotted frame via knobs. The knobs control the height and orientation of the sound level meter and the laser rangefinder, improving measurement accuracy and allowing for rapid on-site installation and adjustment, thus enhancing stability.

[0018] 2. This is a sound level meter bracket for detecting car noise. The telescopic support rod includes two adjusting rods and an adjusting knob. The two adjusting rods are installed via the adjusting button, and the height of the two adjusting rods is controlled by rotating the adjusting knob. Four support legs are installed around the telescopic support rod at equal intervals.
