[0031] The present utility model will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all belong to the protection scope of the present utility model.

[0032] Embodiment 1

[0033] As Figure 1-7As shown in the figure, a vehicle fixing device for an EMC vehicle darkroom according to the present utility model includes: a lower half main body 1, an upper half main body 2, and a gasket 3. One or more gaskets 3 are arranged between the upper half main body 2 and the lower half main body 1. The lower end of the upper half main body 2 is provided with an upper outer edge portion, and the upper end of the lower half main body 1 is correspondingly provided with a lower outer edge portion. The upper outer edge portion, the gasket 3, and the lower outer edge portion are tightly connected; both the upper half main body 2 and the lower half main body 1 are hollow cuboids, and reinforcing ribs are arranged inside both of them. The reinforcing ribs include a plurality of transverse reinforcing ribs and a plurality of longitudinal reinforcing ribs, and the transverse reinforcing ribs and the longitudinal reinforcing ribs are vertically and crosswise arranged; a universal rotating lifting ring 4 is arranged at the top of the upper half main body 2.

[0034] The structures, shapes, and sizes of both the upper half main body 2 and the lower half main body 1 are the same, and the connecting end faces of the upper outer edge portion and the lower outer edge portion overlap.

[0035] The reinforcing ribs are welded into one body by steel plates with a wall thickness of 10 mm.

[0036] Both the upper half main body 2 and the lower half main body 1 are welded into one body by steel plates with a wall thickness of 10 mm. The top of the upper half main body 2 is an iron plate with a thickness of 50 mm, and a screw hole matching the universal rotating lifting ring 4 is opened in the center.

[0037] The gasket 3 includes a galvanized steel plate with a thickness of 2 mm.

[0038] The upper outer edge portion, the gasket 3, and the lower outer edge portion are tightly connected by 8 uniformly distributed bolt assemblies 6. The bolt assemblies 6 include bolts of grade 12.9, nuts, and screw washers.

[0039] In this application, a scheme is taken as an example for illustration, in which it is welded into one body by steel plates with a wall thickness of 10 mm, and then transverse and longitudinal reinforcing ribs are welded by steel plates with a wall thickness of 10 mm in the middle to form a nine-square grid. This wall thickness is designed according to a tensile force of 5 tons. If the customer's requirement for the tensile force changes, different requirements of the customer can be met by adjusting the wall thickness. Round holes are opened in the middle of each grid of the nine-square grid to facilitate firmly fixing the device to the embedded steel plate on the concrete floor through 9 grade 12.9 M18 full-threaded screws. In this way, it is ensured that after a large vehicle is fixed to the fixing device by means of straps, etc., the device will not be deformed such as bending or stretching due to the vehicle's tensile force. The gasket 3 is made of a galvanized steel plate with a thickness of 2 mm, and its main function is to adjust the relative height of the fixing device by the number of gaskets 3, so as to ensure precise installation under the elevated floor in the darkroom.

[0040] The upper half main body 2 of the fixing device is identical in structure, shape, and size to the lower half main body 1. There are 8 through holes with a diameter of Φ20 at the connecting end faces of the upper outer edge part and the lower outer edge part. After the lower half main body 1 is fixed to the embedded part, overlap the connecting end faces of the upper half main body 2 and the lower half main body 1, and then fix the upper and lower parts with 8 sets of 12.9 grade M18 full-thread bolts, 12.9 grade M18 nuts, and M18 screw washers. It should be noted that before fixing the upper half main body 2 to the lower half main body 1, it is necessary to adjust and measure the installation height of the upper half main body 2 through the gasket 3, and adjust the number of gaskets 3 so that the height after the installation of the upper half main body 2 is exactly flush with the surface of the darkroom raised floor; after the upper and lower parts are connected, fix the universal rotating lifting ring 4 into the fixing hole of the upper half through its own bolt.

[0041] A whole iron plate with a thickness of 50 mm is welded to the top of this set of devices. According to the relative size of the universal rotating lifting ring 4 selected according to the pre-designed vehicle pulling force, corresponding screw holes are pre-drilled during processing, and the universal rotating lifting ring 4 is directly fixed into the pre-drilled screw holes on-site. When the customer uses this device, after fixing the strap to the vehicle body, hook the fixed hook at one end of the strap onto the universal rotating lifting ring 4.

[0042] Before the test, the whole vehicle can be fixed to the fixing device of this application through the strap. During the test, if the vehicle accidentally executes commands due to electromagnetic compatibility interference or the laboratory personnel accidentally operate and suddenly start, it can ensure that the vehicle will not rush out accidentally, thus fully guaranteeing the safety of the experimental personnel and other test equipment in the laboratory. The starting inertia impulse of the vehicle is very large, and the design of this device ensures at least a pulling force of 5 tons. For vehicles with a pulling force greater than 5 tons, we can adjust the wall thickness design of this device to ensure the use scenario of a greater inertia impulse.

[0043] Embodiment 2

[0044] An EMC whole vehicle darkroom uses the vehicle fixing device for the EMC whole vehicle darkroom in Embodiment 1. The darkroom raised floor is provided with an installation groove, and the vehicle fixing device for the EMC whole vehicle darkroom is tightly installed in the installation groove, and the upper surface of the upper half main body 2 is flush with the surface of the darkroom raised floor.

[0045] Embedded steel plates are arranged in the concrete floor below the installation groove. The embedded steel plates are connected to the steel bar mesh in the concrete to ensure that the corresponding design pulling force is met. A plurality of through holes are evenly opened at the bottom of the lower half main body 1, and the lower half main body 1 is tightly installed on the embedded steel plate through the screw rod assembly 5. The screw rod assembly 5 includes 12.9 grade full-thread screw rods, nuts, and screw washers.

[0046] Since the whole vehicle to be tested needs to be tested for EMC related tests in specific laboratories such as EMC electromagnetic compatibility anechoic chambers or shielding rooms, the whole vehicle can be fixed to the fixing device of the present application by straps before the test. During the test, if the vehicle accidentally executes commands due to electromagnetic compatibility interference or the laboratory personnel accidentally operate and suddenly start the vehicle, it can be ensured that the vehicle will not rush out accidentally, thus fully guaranteeing the safety of the experimental personnel and other test equipment in the laboratory.
