[0001] This utility model relates to the field of vehicle testing technology, and in particular to a sound level meter mounting bracket and a vehicle noise testing device. Background Technology
[0002] When conducting in-vehicle noise tests, the sound level meter needs to be fixed to the seat back according to the testing standards. Existing car seats include two types: those with separate headrests and backrests, and those with integrated headrests and backrests. The diverse shapes and sizes of car seats present challenges to the installation and securing of the sound level meter.
[0003] Current methods for securing sound level meters typically involve directly attaching them to the seat with tape or using mounting brackets. However, tape attachment suffers from instability, leading to potential positional shifts during testing. Furthermore, the placement of the sound level meter varies significantly between testers, resulting in inconsistent data and poor accuracy. Existing mounting brackets generally rely on the top of the seat back for support, making them unsuitable for seats with integrated headrests and backrests, thus lacking versatility.

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0030] Example 1
[0031] like Figure 1 As shown, when conducting in-vehicle noise testing, the sound level meter (microphone) needs to be fixed to the seat back according to the testing standard requirements, ensuring that the sound level meter is located at sound level meter measuring point 11. As mentioned earlier, the existing sound level meter fixing method has problems such as insecure installation, difficulty in ensuring testing accuracy, and poor versatility.
[0032] Based on this, such as Figure 2 As shown, this embodiment provides a sound level meter mounting bracket, including: a back-mounted mounting component, a first connector 1, a second connector 2, a sound level meter fixing component 3, and a locking fastener; the first connector 1 is slidably connected to the back-mounted mounting component, the end of the first connector 1 is slidably connected to the second connector 2, the sound level meter fixing component 3 is connected to the second connector 2, and the two ends of the locking fastener are respectively connected to the first connector 1.
[0033] In this embodiment, both the first connector 1 and the second connector 2 adopt a rod-shaped structure, and the sound level meter fixing component 3 is a sleeve structure, which is fixedly connected to the end of the second connector 2.
[0034] Optionally, in an embodiment, the back-mounted mounting component includes a connecting plate 4 and a mounting plate 5, wherein the connecting plate 4 is hooked onto the seat of the vehicle to be tested, and one end of the connecting plate 4 is connected to one end of the mounting plate 5.
[0035] Optionally, in the embodiments, such as Figure 3 As shown, the mounting plate 5 has a first elongated hole 6, a first bolt 7 is inserted through the first elongated hole 6, and the end of the first bolt 7 is connected to the first connector 1.
[0036] When the back-mounted mounting bracket is installed on the seat, the first elongated hole 6 is vertically positioned, that is, perpendicular to the plane of the vehicle being tested. After loosening the first bolt 7, the first connecting piece 1 can be moved up and down to adjust its height. After adjusting to the required height, tighten the first bolt 7 to fix the height of the first connecting piece 1. By setting the first elongated hole 6 and the first bolt 7, it can be ensured that seats of different heights can meet the installation standard requirements of the sound level meter.
[0037] Optionally, in an embodiment, there are two first elongated holes 6, which are arranged in parallel.
[0038] Two parallel elongated holes 6 are provided, and a first bolt 7 is inserted through each of the two elongated holes 6. Both first bolts 7 are connected to the first connecting member 1. This ensures that the first connecting member 1 is always in a position perpendicular to the first elongated holes 6, preventing the first connecting member 1 from rotating, and enhancing the installation firmness between the first connecting member 1 and the mounting plate 5.
[0039] In addition to the above method, a first groove parallel to the first elongated hole 6 can be opened on the mounting plate 5, and a first slider can be connected to the first connector 1. The first slider is slidably connected in the first groove, which can also prevent the first connector 1 from rotating.
[0040] Optionally, in this embodiment, the overlapping plate 4 is an arc-shaped structure. The overlapping plate 4 can be a regular arc-shaped structure or an irregular arc-shaped structure, and the specific shape is adjusted and set according to the shape of the vehicle seat.
[0041] Optionally, in an embodiment, the second connector 2 has a second elongated hole 8, a second bolt 9 is inserted through the second elongated hole 8, and the end of the second bolt 9 is connected to the end of the first connector 1.
[0042] After loosening the second bolt 9, the second connecting piece 2 can be moved back and forth, thereby moving the sound level meter fixing piece 3 towards the front or rear of the vehicle. After adjusting to the required position, tighten the second bolt 9 to fix the position of the second connecting piece 2.
[0043] Optionally, in an embodiment, the second connector 2 has a groove parallel to the second elongated hole 8, and the end of the first connector 1 is connected to a slider, which is slidably connected in the groove.
[0044] By setting up a groove and a slider, it is ensured that the second connector 2 can always be in a position perpendicular to the first connector 1, thus preventing the second connector 2 from rotating.
[0045] In addition to the above method, two parallel elongated holes 8 can be made on the second connector 2, and second bolts 9 can be inserted into the two elongated holes 8 respectively. Both second bolts 9 are connected to the first connector 1. This can also prevent the second connector 2 from rotating and enhance the installation firmness between the first connector 1 and the second connector 2.
[0046] Optionally, in this embodiment, the locking fastener is an elastic rope. Specifically, two mounting holes 10 are formed on the first connector 1, and the two ends of the elastic rope pass through the two mounting holes 10 respectively, and the two ends of the elastic rope are fixed respectively.
[0047] In addition to the above method, a first telescopic belt and a second telescopic belt can be provided separately. One end of the first telescopic belt is fixedly connected to the first connecting member 1, and the other end of the first telescopic belt is connected to one end of the second telescopic belt via a buckle. The other end of the second telescopic belt is fixedly connected to the first connecting member 1. The first and second telescopic belts are elastic belts or belts with adjustable lengths, thereby ensuring suitability for different types of seats.
[0048] Optionally, in an embodiment, two second connectors 2 are provided, and the two second connectors 2 are respectively connected to the two ends of the first connector 1.
[0049] The two ends of the first connecting member 1 are slidably connected to the two second connecting members 2 in the manner described above. Each end of the two second connecting members 2 is connected to a sound level meter fixing member 3. The length of the first connecting member 1 is set according to usage requirements to ensure that the distance between the two sound level meters meets the testing standard requirements. Alternatively, a telescopic rod can be used as the first connecting member 1 to adjust the distance between the two sound level meters.
[0050] In use, adjust the height of the first connecting rod and the front-to-back position of the sound level meter fixing component 3 to the specified test position, and fix the first connecting component 1 and the second connecting component 2 with the first bolt 7 and the second bolt 9. The overlapping plate 4 is hooked on the top of the seat, i.e., the headrest position, and the mounting plate 5 and the first connecting component 1 are both located behind the seat back. The two second connecting components 2 are located on both sides of the seat, and the sound level meters are inserted into the two sound level meter fixing components 3 respectively. The elastic rope is then looped around the seat to further securely connect the entire bracket to the seat.
[0051] This bracket connects to the seat via a back-mounted mounting bracket, which can be hooked onto the seat. It is suitable for both seats with separate headrests and backrests and those with integrated headrests and backrests. A locking fastener is included for securing the bracket around the seat, further ensuring a strong connection. Furthermore, the first connecting piece 1 and the back-mounted mounting bracket, as well as the first connecting piece 1 and the second connecting piece 2, are slidably connected, facilitating adjustment of the position of the sound level meter fixing piece 3. Therefore, this bracket can fix the sound level meter at a preset test point, ensuring installation stability, and its high flexibility makes it suitable for various testing scenarios.
