The utility model provides a charging device, including grafting subassembly 1 and support arm 2.

Specifically, the plug assembly 1 includes a charging plug 12, a connecting socket 13 and an elastic member 14, the elastic member 14 is connected between the charging plug 12 and the connecting socket 13, and a seat body is disposed at the bottom of the charging plug 12.

It is understood that the elastic member 14 is provided so that the charging plug 12 can float radially, for example, the charging plug 12 can float up and down, left and right, to adjust the attitude of the charging plug 12.

The supporting arm 2 is slidably connected with the connecting seat 13, so that the whole plug-in module 1 can slide relative to the supporting arm 2, and the plug-in module 1 can extend or retract.

The supporting arm 2 is provided with a supporting seat 21, when the plug assembly 1 is in a retraction state, the supporting seat 21 contacts with the seat body, and the supporting seat 21 upwards supports the seat body.

It can be understood that the supporting seat 21 corresponds to the seat body, and the position of the supporting seat 21 is the position opposite to the seat body when the plug assembly 1 is completely retracted, so that when the plug assembly 1 is in the retracted state, the seat body can fall on the supporting seat 21, and the supporting seat 21 provides the supporting force for the seat body, so as to prevent the charging plug 12 from elastically deforming the elastic element 14 under the action of gravity, and ensure the horizontal posture when the plug assembly 1 is in the standby state.

Obviously, when the plug assembly 1 is extended and plugged into the power receiving socket, the power receiving socket restrains and supports the plug assembly 1, that is, when the charging device is in a charging state, the charging plug 12 does not sag or sag due to the gravity.

That is, the charging device provided by the utility model, by arranging the seat body at the bottom of the charging plug 12, and a supporting seat 21 is arranged at the position of the supporting arm 2 corresponding to the seat body, the supporting seat 21 plays a role of supporting the whole inserting assembly 1 through the seat body by utilizing the matching effect of the seat body and the supporting seat 21 when the inserting assembly 1 is in a withdrawing state, so as to counteract the gravity action of the charging plug 12, avoid the charging plug 12 from drooping due to the gravity action, and ensure the posture of the charging plug 12 in a standby state, thus, when the charging device is in standby for a long time, the elastic piece 14 can be prevented from being in an elastic deformation state for a long time, the elastic piece 14 is prevented from being damaged along with the increase of the service time, and the charging plug 12 can be ensured to extend out in a fixed pose in the charging process at every time, so that the charging plug 12 and the vehicle powered device can be accurately plugged and charged.

It should be noted that, in this embodiment, the specific structure of the seat body is not limited, and in consideration of the stability of the contact, on the basis of the above embodiments, the seat body is the cushion block 11, and the cushion block 11 is fixedly connected with the charging plug 12.

It will be appreciated that the support base 21 includes a support surface 211 and that during retraction of the plug assembly 1, the spacer 11 slides into full contact with the support surface 211.

It can be understood that, in the process of retracting the plug assembly 1, when the seat body contacts the supporting seat 21, the seat body moves relative to the supporting seat 21, in this embodiment, after the cushion block 11 contacts the supporting surface 211, and the cushion block 11 slides relative to the supporting surface 211 until the plug assembly 1 is fully retracted, so that the cushion block 11 completely contacts the supporting surface 211, and the supporting surface 211 provides stable support for the cushion block 11.

In view of the fact that the support of the plug assembly 1 is lost at the moment when the plug assembly 1 is separated from the power receiving socket, that is, the plug assembly 1 is drooped by gravity between the time when the plug assembly 1 is just withdrawn and the time when the plug assembly 1 is withdrawn and the spacer 11 is contacted with the support surface 211, on the basis of the above embodiment, the first slope surface 111 is provided on the side of the spacer 11 facing away from the extending direction of the plug assembly 1 in order to enable the spacer 11 to move smoothly.

Preferably, the lowest end of the first sloped surface 111 extends to the contact surface 112 where the pad 11 abuts the support surface 211.

That is, when the pad 11 initially contacts the supporting surface 211, the highest end of the first slope surface 111 first contacts one side of the supporting surface 211, and as the plug assembly 1 continues to retract, the pad 11 gradually contacts the supporting surface 211 along the first slope surface 111 until the bottom surface of the pad 11 completely contacts the supporting surface 211, which can ensure the stability of the plug assembly when retracting.

Of course, when the plug assembly 1 is in the retracted state, a certain portion of the first slope surface 111 may be supported on the supporting seat 21 as long as the supporting seat 21 can provide a supporting force to the cushion block 11.

On the other hand, in order to reduce the frictional resistance of the support base 21 to the housing body during the retraction of the plug-in module 1, as another preferable solution, on the basis of the above embodiment, the housing body includes the rolling member, and the rolling member is rotatably connected to the charging plug 12. That is, during retraction of the plug assembly 1, the rolling member rolls along the support surface 211 to a final stop position.

That is, in this embodiment, after the rolling member contacts the supporting surface 211, the rolling member contacts the supporting surface 211 in a point manner, and the rolling member rolls with respect to the supporting surface 211 until the plugging member 1 is completely retracted, so that the rolling member finally stops at the predetermined position of the supporting seat 21.

In addition, in each of the above embodiments, the specific structure of the support seat 21 is not limited as long as the support seat 21 can provide a supporting force for the seat body.

As a preferable scheme, on the basis of the above embodiment, the supporting seat 21 includes a supporting surface 211 and a second slope surface 212, the supporting surface 211 is used for being in contact with the seat body to provide a supporting force for the seat body; the second slope surface 212 is disposed obliquely toward the side of the plug assembly 1 in the protruding direction.

Preferably, the uppermost end of the second ramp surface 212 is connected to the support surface 211.

As can be seen from the above, in the retracting process of the plug assembly 1 before the seat body contacts the supporting seat 21, the plug assembly 1 hangs down under the action of gravity, after the seat body completely contacts the supporting seat 21, the plug assembly 1 is straightened, and in order to ensure the moving stability of the plug assembly 1 from the time when the seat body just contacts the supporting seat 21 to the time when the seat body completely contacts the supporting seat 21, the second slope surface 212 is provided in the embodiment, so that the seat body just contacts the supporting seat 21, and gradually transits to the supporting surface 211 along the second slope surface 212 to ensure the moving stability of the plug assembly 1.

In view of the simplicity of the structure of the support base 21 and the ease of implementation, the support base 21 is a plate-shaped bent piece based on the above-mentioned embodiment.

That is, the second slope surface 212 and the support surface 211 of the support base 21 are formed by bending a plate-shaped member.

Further, in consideration of the convenience of the arrangement of the support base 21, as shown in fig. 2, on the basis of the above embodiment, the support base 21 further includes an L-shaped fixing surface 213 connected to the support surface 211, and the L-shaped fixing surface 213 is connected to the support arm 2 by a bolt.

That is, the supporting seat 21 in this embodiment is formed by bending a plate-shaped member into an integrated structure having the second slope surface 212, the supporting surface 211 and the L-shaped fixing surface 213, and has a simple structure and convenient connection.

Further, on the basis of the above embodiment, the plug-in assembly 1 further includes a guide rod 15 and an axial limiting member, the guide rod 15 is disposed between the charging plug 12 and the connecting seat 13, a first end of the guide rod 15 is fixedly connected to the charging plug 12, a second end of the guide rod 15 is radially movably disposed on the connecting seat 13, the axial limiting member is disposed at a second end of the guide rod 15, and the axial limiting member is located on one side of the connecting seat 13 far away from the charging plug 12 and is used for being matched with one side of the connecting seat 13 far away from the charging plug 12 for limiting.

It can be understood that, because the elastic member 14 is arranged between the charging plug 12 and the connecting seat 13, the elastic member 14 can elastically deform or deform under the action of external force, and because the first end of the guide rod 15 is fixedly connected with the charging plug 12, and the second end of the guide rod 15 can radially move relative to the connecting seat 13, when the external force acts on the charging plug 12, the charging plug 12 can float up and down, left and right, in the process, the elastic member 14 can freely bend towards the radial direction, and meanwhile, the second end of the guide rod 15 can radially move to adapt to the up-down, left-right floating of the charging plug 12, so as to avoid interfering with the up-down floating of the charging plug 12; meanwhile, the radial movable range of the second end of the guide rod 15 can limit the range of up-down, left-right floating of the charging plug 12.

In addition, due to the existence of the axial limiting piece, in the process of stretching the charging plug 12 along the axial direction, when the charging plug 12 is stretched to a certain position, the axial limiting piece is in contact with one side, far away from the charging plug 12, of the connecting seat 13 in a fitting manner, so that the elastic piece 14 can be prevented from being stretched infinitely along the axial direction; meanwhile, after the axial limiting member contacts the connection seat 13, the connection seat 13 may be driven to move along the slide rail of the support arm 2, so that the charging plug extends out to be inserted into the power receiving socket.

When the charging plug is withdrawn after being pulled out from the power receiving socket, the charging plug 12 compresses the elastic part 14, and in the process, due to the existence of the guide rod 15, the elastic part 14 is compressed in a certain axial direction, so that the elastic part 14 can be freely compressed.

In addition, in each of the above embodiments, the utility model discloses do not restrict the concrete structure of support arm 2, in order to practice thrift the whole shared space of charging device, guarantee simultaneously that charging device has great stroke when stretching out, as a preferred embodiment, on the basis of the above-mentioned embodiment, support arm 2 is the flexible cover that can axially stretch out and draw back.

That is to say, the supporting arm 2 in this embodiment is retractable, and when the power receiving receptacle needs to be charged, not only the plug assembly 1 can extend out relative to the supporting arm 2, but also the supporting arm 2 itself can extend, so that the plug assembly 1 can extend out by a larger stroke.

In addition, after the plug assembly 1 is completely retracted, the telescopic cover serves as a shell assembly, the plug assembly 1 can be hidden in the telescopic cover, and the plug assembly 1 is protected to a certain extent.

At this time, as shown in fig. 1 and 2, the support base 21 is provided on the inner wall of the tip end expansion cover closest to the plug module 1.

It should be noted that, in this embodiment, a specific manner of extending and retracting the telescopic cover is not limited, for example, the telescopic cover may be extended and retracted by a link extending and retracting mechanism (e.g., a scissors mechanism).

It is further noted that, in the present specification, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
