PARTICULAR EMBODIMENTS
The present utility model will be described in further detail below in combination with the accompanying drawings.
Referring to fig. 1, fig. 1 shows schematically a simplified structural drawing of a grounding member according to an embodiment of the present utility model.
The grounding member 100 as shown in fig. 1 comprises a wire connecting part 101, a through-hole part 102 and an elastic anti-detachment part 103.
The wire connecting part 101 is used for connecting a ground wire 400; the through-hole part 102 is used for connecting to a vehicle body part 300 of the vehicle by means of a threaded connecting structure 200; the elastic anti-detachment part 103 is used for snap-fitting to the vehicle body part 300 of the vehicle in order to connect the grounding member 100 to the vehicle body part 300.
The wire connecting part 101, the through-hole part 102 and the elastic anti-detachment part 103 are rigidly connected.
More preferably, the grounding member 100 containing the wire connecting part 101, the through-hole part 102 and the elastic anti-detachment part 103 is a one-piece member.
Preferably, the elastic anti-detachment part 103 comprises a V-shaped elastic clip.
Two sides of a V-shaped part thereof can deform when subjected to pressure, such that an opening of the V-shape becomes smaller; when the pressure has disappeared, the opening of the V-shape recovers its original form.
Now referring to fig. 2, fig. 2 shows schematically a simplified schematic diagram of a vehicle body part 300 for fitting with a grounding member 100. The vehicle body part comprises a first hole 301 and a second  hole 302.
The first hole 301 corresponds to the through-hole part 102 of the grounding member 100, and the second hole 302 is matched to the elastic anti-detachment part 103 of the grounding member 100, i.e. the distance between the first hole 301 and the second hole 302 corresponds to the distance between the through-hole part 102 and the elastic anti-detachment part 103.
The vehicle body part 300 is a part of a frame of the entire vehicle; for conciseness, those parts thereof, which are relevant to the present utility model, are displayed and explained herein.
Now referring to figs. 3, 4, 5a and 5b, fig. 3 shows schematically a simplified schematic diagram of various parts of a grounding structure for use in a vehicle; the grounding structure as shown in fig. 3 comprises a grounding member 100, a threaded connecting structure 200 and a vehicle body part 300 of the vehicle. Fig. 4 shows schematically a schematic diagram of a grounding structure after installation; fig. 5a shows schematically a top view of a grounding structure after installation; fig. 5b shows schematically a sectional view of the grounding structure as shown in fig. 5a along line A-A. The threaded connecting structure 200 passes through the first hole 301 of the vehicle body part 300, and the through-hole part 102 of the grounding member 100; the elastic anti-detachment part 103 of the grounding member 100 passes through the second hole 302 of the vehicle body part 300.
The threaded connecting structure 200 comprises a bolt 201 and a nut 202, the vehicle body part 300 comprises the first hole 301 and the second hole 302, the first hole 301 is configured to correspond to the through-hole part 102 in the grounding member 100, and the second hole 302 is configured to correspond to the elastic anti-detachment part 103 in the grounding member 100, wherein the wire connecting part 101 of the  grounding member 100 is connected to the ground wire 400 of the vehicle; the bolt 201 in the threaded connecting structure 200 passes through the through-hole part 102 of the grounding member 100 and the first hole 301 in the vehicle body part 300 and is fitted to the nut 202, such that the grounding member 100 is connected to the vehicle body part 300; the elastic anti-detachment part 103 of the grounding member 100 is fitted to the second hole 302 in the vehicle body part 300, such that the grounding member 100 is snap-fitted to the vehicle body part 300.
The elastic anti-detachment part 103 of the grounding member comprises a V-shaped elastic clip 1031, which has a V-shaped body part 1032 and an opening 1033, wherein the V-shaped body part 1032 can deform under pressure, such that two sides of the V-shaped body part 1032 draw close to each other and the opening 1033 becomes smaller, and can thus pass through the second hole 302, and when the pressure has disappeared, the V-shaped opening 1033 opens to recover its original size, locking into the second hole 302, such that the V-shaped body part 1032 is held at another side of the vehicle body part 300, so that the grounding member 100 is connected to the vehicle body part 300.
For convenience of explanation, the orientations of the various parts of the grounding structures shown in figs. 3 and 5a are the opposite of the actual orientations; those skilled in the art will understand that when actual installation is carried out, the wire connecting part 101 and through-hole part 102 of the grounding member 100 are on a side of the vehicle body part 300 that is close to the ground, whereas the elastic anti-detachment part 103 is on another, upward-facing side of the vehicle body part 300.
Preferably, the grounding structure according to the present utility model is contained in a vehicle.
Compared with the prior art, the present utility model has the following advantages: the grounding member can be conveniently snapped into the  vehicle body part by means of the elastic anti-detachment part, thereby avoiding the grounding member loosening from the vehicle body due to loosening of the threaded connection, and in turn ensuring that the vehicle always has good EMC performance for a long period of time.
To a person skilled in the art, it is obvious that the present utility model is not limited to the details of the demonstrative embodiments above, and it is possible to implement the present utility model in other specific forms without deviating from the spirit or fundamental features of the present utility model. Thus, regardless of which viewpoint is taken, the embodiments should be regarded as being demonstrative and non-limiting, and the scope of the present utility model is defined by the attached claims and not by the explanation above, hence it is intended that all changes falling within the meaning and scope of equivalent important conditions of the claims be included in the present utility model. No referenced labels in the claims should be regarded as limiting the relevant claims. In addition, it is obvious that the word “comprises” does not exclude other units or steps, and the singular does not exclude the plural. One unit or apparatus by means of software or hardware may also realize multiple units or apparatuses presented in system claims. Words such as first and second are used to indicate designations, and do not indicate any specific order.
