It please refers to Fig.1, Fig. 2, Fig. 3 and Fig. 4, is mainly included according to the exemplary vehicle electric element earthing or grounding means of the utility model：
Earth stud 10, ground terminal 20, nut 30 and anti-rotation structure 40.Wherein, earth stud 10 is grounded by being connected with vehicle body,
It can be affixed between earth stud 10 and vehicle body, such as weld.One end of ground terminal 20 is used to connect with the harness of vehicle electric element
It connects, the other end is sheathed on earth stud 10, is pressed on by nut 30 on earth stud 10, so as to connecing by earth stud 10
Ground and be grounded.Anti-rotation structure 40 is used to limit the rotation of ground terminal 20, which is equipped with first through hole 41, anti-rotation knot
Structure 40 is sheathed on a part for earth stud 10 by the first through hole 41, and passes through 41 inner wall of first through hole and earth stud
10 lean, to prevent circumferentially rotating between anti-rotation structure 40 and earth stud 10 and move radially.Further, anti-rotation structure
40 can be equipped with terminal limit space 42, for accommodating ground terminal 20, and limit the week between ground terminal 20 and anti-rotation structure 40
To rotation, thus by being arranged at the first through hole 41 of anti-rotation structure 40 and the coordinated of terminal limit space 42, to ground connection
Terminal 20 is limited with earth stud 10 for circumferentially rotating for center of rotation.It may be noted that terminal limit space 42 is not
It is simply possible to use in and prevents circumferentially rotating for ground terminal 20 completely, can also be only used for what limitation ground terminal 20 was circumferentially rotated
Amplitude.
In some embodiments, earth stud 10 includes the bolt head 11 being connected with vehicle body, sets threaded shank of bolt
Portion 12 and the ring flange 13 between bolt head 11, bar portion 12.One end of ground terminal 20 and the harness of electric appliance connect
It connects, the other end is equipped with connecting hole, and by the connecting hole, ground terminal 20 can be sheathed on bolt shank 12.Nut 30 is sheathed on spiral shell
Bolt stem 12, and compressed to 11 direction of bolt head, ground terminal 20 is pressed on ring flange 13.Optionally, nut 30
Washer can be placed between ground terminal 10, between ground terminal 10 and ring flange 13.
It can be by selecting the earth stud 10 that at least part of cross section is regular polygon, and by the horizontal stroke of first through hole 41
Cross sectional shape is arranged to match with the shape of the regular polygon structure of earth stud 10, to realize anti-rotation structure 40 and ground connection spiral shell
Engaging between bolt 10.In some embodiments：
The earth stud 10 includes the ring flange 13 of regular prism shape structure, and cross section is in regular polygon.It may be noted that institute here
The regular prism said is not necessarily the regular prism on strict mathematical sense, for example, the corner angle of ring flange 13 can be fillet.This is anti-
Rotation structure 40 is ground connection disk, including roughly cylindrical 40 body of anti-rotation structure.The middle part of 40 body of anti-rotation structure is equipped with
The first through hole 41 penetrated through vertically, the shape of 41 cross section of first through hole are to match just with 13 cross-sectional shape of ring flange
Polygon so as to which anti-rotation structure 40 can be sheathed on outside earth stud 10, and is prevented between anti-rotation structure 40 and earth stud 10
It is circumferentially rotated and is moved radially.Optionally, the axial length of 40 body of anti-rotation structure may be approximately equal to or slightly larger than spiral shell
The sum of 11 axial length of bolt head and 13 axial length of ring flange.
Further, foregoing regular polygon can be octagonal structure, and octagonal structure is than hexagon, quadrangle limitation
Face is more, so as to reach better anti-rotation effect using octagonal structure.
It may be noted that the first through hole 41 and earth stud 10 of anti-rotation structure 40 and the horizontal stroke of the mating part of first through hole 41
Section may not be regular polygon, but arbitrary graphic than circular, such as can be arbitrary polygon or even can
To be irregular figure.In addition, the shape of the mating part of first through hole 41 and earth stud 10 is also not necessarily limited to prismatic, example
Such as can be terrace with edge, and the cross-sectional area of the close vehicle body position of the terrace with edge is more than the cross section of the separate vehicle body position of the terrace with edge
Product.
In some embodiments, earth stud 10 is additionally provided with the first card slot, may be provided at bolt head 11 or ring flange 13
On, meanwhile, the inner wall of first through hole 41 is equipped with the corresponding first buckle 43, by the first card slot with first be buckled 43 engaging come
Anti-rotation structure 40 is prevented to be moved along earth stud 10 is axial.In a kind of concrete mode, which includes ring flange 13
Gap between vehicle body：Bolt head 11 is cylindrical structural, and ring flange 13 is regular prism shape structure, bolt head 11 it is outer
Footpath is less than the outer diameter of ring flange 13, and vehicle body, the outer wall of bolt head 11 and ring flange 13 is made to be formed close to the outer wall of vehicle body one side
For the first card slot；The first buckle 43 is equipped in 41 inner wall of first through hole position corresponding with first card slot, passes through the first card slot
Engaging with the first buckle 43 prevents anti-rotation structure 40 from being moved along earth stud 10 is axial；In fact, mainly by the
One buckle 43 offsets on one side with ring flange 13 close to vehicle body, to prevent anti-rotation structure 40 along earth stud 10 axially away from vehicle body.
Wherein, the terminal limit space 42 of anti-rotation structure 40 can be flute profile, or hole shape.In some implementations
In example, anti-rotation structure 40 is ground connection disk, and including roughly cylindrical 40 body of anti-rotation structure, 40 body of anti-rotation structure is axial
Both ends tool is there are two bottom surface, and the bottom surface away from vehicle body is equipped with multiple boss 44, these boss 44 are along between the circumferential direction of anti-rotation structure 40
Every arrangement, the terminal limit space 42 for the flute profile that can accommodate ground terminal 20 is formed between boss 44 two-by-two.In ground terminal
When one end of son 20 is sheathed on the bar portion of earth stud 10, the other end of ground terminal 20 can be worn from terminal limit space 42
Go out, and the boss 44 of 42 both sides of terminal limit space can limit ground terminal 20 and turn compared with the circumferential direction of anti-rotation structure 40
It is dynamic.In a kind of concrete mode, boss 44 is five, so as to form five terminal limit spaces 42.
Optionally, anti-rotation structure 40 is also provided with upper cover 45, and upper cover 45,40 body of anti-rotation structure are respectively equipped with the second card
Button, the second card slot, make upper cover 45 be fastened on 40 body of anti-rotation structure, and upper cover 45 is equipped with the second through hole 46, so that earth stud
10 can be pierced by from second through hole 46.The shape of second through hole 46 is not limited.In a kind of example, anti-rotation structure 40
Boss 44 be equipped with the second card slot, the correspondence position of upper cover 45 is equipped with the second buckle, passes through the second buckle and the second card slot
Cooperation, upper cover 45 can be fastened on 40 body of anti-rotation structure, make the terminal limit space 42 of flute profile become hole shape, connect for accommodating
Ground terminal 20 carries out /V to ground terminal 20, can also prevent coming off for ground terminal 20, such as can prevent in transportational process
Ground terminal 20 drops.Optionally, upper cover 45 is also affixed by connect band and 40 body of anti-rotation structure, for example, upper cover 45 with
40 body of anti-rotation structure can be integrally formed, to prevent the dropping of upper cover 45, lose.Optionally, 45 outer surface of upper cover can
Equipped with Digital ID, for distinguishing each ground terminal 20.
The invention also discloses a kind of vehicle, the vehicle electric element ground connection dress including any one above-mentioned embodiment
It puts, for the ground connection of vehicle electric element, and the rotation of ground terminal 20 can be limited.
