Description
Technical Field
[0001] The present invention belongs to the technical field of vehicle design and grounding equipment, and in particular relates to an integrated grounding device based on a vehicle. Background Art
[0002] Vehicles carrying shelters or with strict grounding requirements are equipped with a variety of electronic equipment. These devices require extremely low impedance grounding points, and the reliability of grounding will directly affect the working stability and electromagnetic compatibility of the equipment. The relevant national standards clearly stipulate that "the resistance between the grounding terminal of the equipment and the vehicle body should not be greater than 0.02Ω". At present, the tires of vehicles are rubber structures, and the metal structural parts of the vehicle, such as the frame and cab, are not directly connected to the ground plane, but are connected to the negative pole of the battery through the negative pole grounding method. However, this grounding method is not standardized, resulting in poor grounding effect, which affects the electrical function of the vehicle and the electromagnetic compatibility of the equipment. Summary of the invention
[0003] The invention has a standardized grounding device, thereby achieving the purpose of ensuring the grounding effect of the vehicle and ensuring the electrical function of the vehicle and the electromagnetic compatibility of the equipment.
[0004] In order to solve the problems in the above background technology, the present invention is implemented by the following technical solutions:
[0005] A vehicle-based integrated grounding device comprises a box body mounted on a vehicle frame via a mounting piece, one side of the box body is provided with an opening, a cover body is hingedly connected to the box body corresponding to the opening, and a fixing piece for fixing the cover body is provided between the box body and the cover body; a first metal plate is connected to the box body via a grounding cable, and a grounding piece connected to the earth is provided on the first metal plate.
[0006] As a further description of the invention: the mounting member includes a grounding bolt, one end of which extends into the interior of the box and is connected to the grounding cable, and the other end of which is located outside the box and is used to fix the box to the frame.
[0007] As a further explanation of the invention: the grounding bolt is a long bolt.
[0008] As a further explanation of the invention: the grounding bolt is connected to the grounding cable through a second metal plate.
[0009] As a further explanation of the invention: the grounding bolt is arranged to penetrate the second metal plate, and a fixing hole corresponding to the grounding bolt is arranged on the first metal plate.
[0010] As a further description of the invention: the grounding member is a grounding steel needle, and the tip of the grounding steel needle is arranged in a direction away from the first metal plate.
[0011] As a further explanation of the invention: conductive anti-rust material is coated between the grounding bolt and the vehicle frame, or between the grounding bolt and the grounding cable, or between the grounding steel needle and the grounding cable, or any two or three of the above.
[0012] As a further explanation of the invention: there are two grounding steel needles.
[0013] As a further explanation of the invention: a waterproof ring is provided on the box body for waterproofing.
[0014] As a further illustration of the invention: the fixing member comprises a buckle.
[0015] Compared with the prior art, the present invention has the following beneficial technical effects:
[0016] 1. When the grounding device is in use, open the cover, take out the first metal plate, and insert the grounding steel needle into the ground; when recycling, wrap the grounding cable around the grounding bolt in the box, and then make the tip of the grounding steel needle face the inside of the box, insert the grounding bolt into the fixing hole, use the first metal plate to compress the grounding cable wrapped around the grounding bolt, and then take the nut and thread it to the grounding bolt, fix the first metal plate and the grounding bolt, and finally close the cover. This standardizes the grounding device and ensures the grounding effect of the vehicle, thereby avoiding the electrical function of the vehicle and the electromagnetic compatibility of the equipment being affected. The coordinated setting of the first metal plate and the grounding bolt makes it easier to store and organize the grounding cable, so that the grounding cable is not easy to be tangled and knotted in the box, which is convenient for subsequent reuse.
[0017] 2. If the vehicle needs to be grounded during use, the box can be directly installed on the appropriate part of the frame through the grounding bolt, and then the first metal plate is taken out and the grounding steel needle is inserted into the ground to avoid the impedance instability caused by the use of a temporary grounding device, which affects the normal operation of the equipment. The grounding device is easy to install and simple to use.
[0018] 3. There are two grounding steel needles, which makes the grounding device more stable when inserted into the ground and not easy to loosen or fall out.
[0019] 4. Conductive anti-rust material is coated between the grounding bolt and the frame, between the grounding bolt and the grounding cable, and between the grounding steel needle and the grounding cable, which can ensure the low impedance characteristics of the connection between the grounding bolt and the frame, the low impedance characteristics of the connection between the grounding bolt and the grounding cable, and the low impedance characteristics between the grounding cable and the grounding steel needle.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] like Figure 1-3As shown, an integrated grounding device based on a vehicle includes a box body 2, an opening is provided on one side of the box body 2, a cover body 21 is hingedly connected to the corresponding opening on the box body 2, a fixing part for fixing the cover body 21 is provided between the box body 2 and the cover body 21, and the fixing part includes a buckle 22. Since the buckle 22 is a prior art, the specific structure is not described here. A waterproof ring is provided on the box body 2. Specifically, the waterproof ring is provided at the opening of the box body 2, and can also be provided at the cover body 21, which is used to increase the sealing after the cover body 21 and the box body 2 are covered, thereby improving the waterproof performance of the box body 2.
[0029] The box body 2 is installed on the frame 1 through a mounting part. Specifically, the mounting part includes a grounding bolt 4. One end of the grounding bolt 4 extends into the interior of the box body 2 and is connected to a grounding cable 5 through a second metal plate 3. The other end is located outside the box body 2 and is used to fix the box body 2 on the frame 1. The grounding cable 5 is a low-impedance cable. The grounding bolt 4 is arranged to penetrate the second metal plate 3 and is a long bolt, so that the grounding cable 5 can be wrapped around the long bolt for storage. Two grounding bolts 4 are provided, so that the box body 2 is more stable when fixed to the frame 1.
[0030] One end of the grounding cable 5 away from the grounding bolt 4 is connected to a first metal plate 6, and a grounding piece connected to the earth is provided on the first metal plate 6, and the grounding piece is a grounding steel needle 7, and the tip of the grounding steel needle 7 is set in a direction away from the first metal plate 6, and there are two grounding steel needles 7, so that the grounding device is more stable when inserted into the ground and is not easy to loosen and fall out. Among them, the grounding steel needle 7 is detachably arranged on the first metal plate 6, so that the grounding steel needle 7 is replaceable. The specific detachable connection method between the grounding steel needle 7 and the first metal plate 6 can be either plug-in or threaded connection, which is not further limited here.
[0031] A fixing hole 61 is provided on the first metal plate 6 corresponding to the grounding bolt 4.

The grounding cable 5 wound around the grounding bolt 4 is compressed by the first metal plate 6, and then a nut is threadedly connected to the grounding bolt 4 to fix the first metal plate 6 and the grounding bolt 4. This makes it easier to store and organize the grounding cable 5, so that the grounding cable 5 is not easily tangled or knotted in the box body 2, which is convenient for subsequent reuse.
[0032] Conductive anti-rust material is coated between the grounding bolt 4 and the frame 1, or between the grounding bolt 4 and the grounding cable 5, or between the grounding steel needle 7 and the grounding cable 5, or any two or all three of the above, so as to ensure the low impedance characteristics of the connection between the grounding bolt 4 and the frame 1, the low impedance characteristics of the connection between the grounding bolt 4 and the grounding cable 5, and the low impedance characteristics between the grounding cable 5 and the grounding steel needle 7.
[0033] The working principle of the present invention is as follows: when the vehicle needs to be grounded during use, the box body 2 can be directly installed on the appropriate position of the frame 1 through the grounding bolt 4, and then the cover body 21 can be opened, the first metal plate 6 can be taken out, and the grounding steel needle 7 can be inserted into the ground; when recycling, the grounding cable 5 is wound around the grounding bolt 4 in the box body 2, and then the tip of the grounding steel needle 7 is directed toward the inside of the box body 2, the grounding bolt 4 is inserted into the fixing hole 61, and the grounding cable 5 wound around the grounding bolt 4 is compressed with the first metal plate 6, and then the nut is threadedly connected to the grounding bolt 4, the first metal plate 6 and the grounding bolt 4 are fixed, and finally the cover body 21 is closed. In this way, the grounding device is standardized, the grounding effect of the vehicle is guaranteed, and the electrical function of the vehicle and the electromagnetic compatibility of the equipment are avoided from being affected. In addition, the coordinated arrangement of the first metal plate 6 and the grounding bolt 4 makes it easier to store and organize the grounding cable 5, so that the grounding cable 5 is not easy to be entangled and knotted in the box body 2, which is convenient for subsequent reuse.
