Description

Technical Field

[0001] The utility model relates to the technical field of vehicle testing, in particular to a fixing device for vehicle dust-proof sealing experiments. Background Art

[0002] The vehicle dust-proof sealing test is one of the sign-off items in the vehicle development process. Before the vehicle prototype product is launched on the market, this test must be completed to verify the dust-proof sealing performance of the vehicle. In the vehicle dust-proof sealing test, a dust sampler is required to collect dust and measure its concentration. During the test, the dust sampler extracts air at a certain flow rate to collect the dust in the air, and then measures the dust mass inside and outside the vehicle respectively, and calculates the dust concentration inside and outside the vehicle.

[0003] The basic structure of the dust sampler is shown in a dust sampler disclosed in the utility model patent with the publication number CN207408162U, which includes a housing and a motor, an air pump, a flow meter and a sampling head connected in sequence. Among them, the motor, the air pump and the flow meter are fixed inside the housing, and the sampling head is fixed on the housing in a horizontal cantilever state. The sampling head is cylindrical and includes a base, a mesh plate, a filter membrane clamping mechanism, a fastening mechanism and a flow guide cover. The base is fixed on the housing, and the flow guide cover, the filter membrane clamping mechanism and the base are connected by a horizontally and eccentrically arranged rotating shaft. The filter membrane clamping mechanism is located between the flow guide cover and the base. The flow guide cover is slidably connected to the rotating shaft, and the filter membrane clamping mechanism is rotatably connected to the rotating shaft so that it can rotate relative to the flow guide cover and the base around the rotating shaft. The mesh plate is arranged between the filter membrane clamping mechanism and the base, and the fastening mechanism is connected between the flow guide cover and the base to control the sliding of the flow guide cover along the rotating shaft to clamp the filter membrane clamping mechanism.

[0004] However, when the above-mentioned dust sampler is used in the vehicle dust-proof sealing test, there is a lack of a fixing device that can fix it on the vehicle. If the dust sampler is not properly fixed, it will not only fail to ensure the accuracy of the measured dust concentration data, affect the effectiveness of the test, but also easily cause damage to the instrument, increasing the risk and cost of the test.

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a fixing device for the whole vehicle dust-proof sealing test, and the specific structure is as follows:

[0028] A fixing device for the whole vehicle dust-proof sealing test is used to fix the dust sampler 1. As Figure 1 and Figure 2 shown, the dust sampler 1 is used to measure the dust concentration inside and outside the vehicle, and an annular handle 11 is provided thereon. The fixing device for the whole vehicle dust-proof sealing test includes a support rod 2 and a support 3 for carrying the dust sampler 1. The support rod 2 passes through the annular handle 11 to limit the movement range of the dust sampler 1; the support 3 is connected to the vehicle, one end of the support rod 2 is connected to the support 3, and the other end is connected to the vehicle. During use, through the common limitation of the support rod 2 passing through the handle and the support 3 carrying the dust sampler 1, it can be ensured that the position of the dust sampler 1 remains unchanged during the test, thereby ensuring the accuracy and reliability of the test data.

[0029] The vehicle for testing includes a window, and the window includes an upper window ledge and a lower window ledge. To ensure the stability of the fixing of the support rod 2, as Figure 2 shown, the support rod 2 is connected to the upper window ledge of the window through a first fixing part 4. The first fixing part 4 includes a clamping member for clamping the upper window ledge, and the clamping member includes a first clamping arm 41 and a second clamping arm 42 respectively arranged on both sides of the upper window ledge. The first clamping arm 41 is connected to the support rod 2, and the second clamping arm 42 is connected to the support 3 through a fixing rod 5. To facilitate the disassembly and assembly of the clamping member and the upper window ledge without damaging the vehicle, the first clamping arm 41 and the second clamping arm 42 are detachably connected.

[0030] In some embodiments, to be able to fix window sills of different thicknesses, the distance between the first clamping arm 41 and the second clamping arm 42 is adjustable. In a specific embodiment, threaded holes are provided on both the first clamping arm 41 and the second clamping arm 42. The first clamping arm 41 and the second clamping arm 42 are connected by a bolt that sequentially passes through the two threaded holes. An adjusting nut 6 for restricting the telescopic limit of the bolt is sleeved on the bolt. During adjustment, by rotating the bolt and using the adjusting nut 6 to fix the bolt, the distance between the two clamping arms can be finely adjusted, so as to ensure that the clamping member can clamp window sills of different thicknesses, thereby improving the adaptability of the fixing device.

[0031] To ensure the stability of the fixing of the support 3, as Figure 1 and Figure 2 shown, the support 3 is connected to the window sill of the window through the second fixing portion 7. The second fixing portion 7 includes a first clamping member 71 and a second clamping member 72 that are connected to each other. The first clamping member 71 is connected to the upper window sill of the window, and the second clamping member 72 is connected to the lower window sill of the window. By such a double-point fixing method from top and bottom, the shaking or displacement of the support 3 during the test can be effectively prevented, thereby improving the stability and reliability of the entire system. In a specific embodiment, a first groove 73 for clamping with the upper window sill is provided on the first clamping member 71, and a second groove 74 for clamping with the lower window sill is provided on the second clamping member 72. The design of the groove allows the fixing device to be disassembled and assembled without damaging the original structure of the sample vehicle. While protecting the sample vehicle itself from damage, good flexibility is provided.

[0032] In some embodiments, to ensure that the first clamping member 71 and the second clamping member 72 can cooperate closely and can be disassembled and assembled conveniently, the first clamping member 71 and the second clamping member 72 are detachably connected.

[0033] As a further improvement of the above embodiment, to cope with windows of different sizes, the position of the first clamping member 71 relative to the second clamping member 72 is allowed to be adjustable within a certain range. As Figure 1 shown, a strip-shaped groove 8 is provided on the first clamping member 71, and at least one mounting hole is provided on the second clamping member 72. The first clamping member 71 and the second clamping member 72 are connected by a bolt that sequentially passes through the strip-shaped groove 8 and the mounting hole. During adjustment, the position where the bolt is connected to the strip-shaped groove 8 is allowed to change, so that the position of the first clamping member 71 relative to the second clamping member 72 is adjustable to adapt to the window sills of different vehicle models, increasing the versatility and adaptability of the fixing device. The number of mounting holes is preferably two, which provides better stability for the fixing of the first clamping member 71 and the second clamping member 72.
