Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 14, an electric vehicle 2 provided by the present application includes a vehicle body and a power receiving device, the power receiving device is disposed at a bottom of one end of the vehicle body, and the power receiving device has a docking portion 21.

Specifically, the power receiving device is arranged at the bottom of one end of the vehicle body, wherein one end of the electric vehicle 2 comprises a front end, a rear end, a front side end and a rear side end; the front end refers to a middle area in the width direction of the head of the electric vehicle 2, a middle area from the front end to the width direction of the tail of the electric vehicle 2, the front end comprises a left area and a right area which are located on two sides of the front end, and the rear end comprises a left area and a right area which are located on two sides of the front end. The bottom of the electric vehicle 2 includes a chassis region and a middle-lower region of a vehicle body (including a head and a tail) near the chassis. In summary, the bottom portion of one end of the electric vehicle 2 may be a combined area of any one of the end portions and any one of the bottom portions.

The docking portion 21 of the power receiving device can be docked with the charging connector 13 of the charging device 1 to be charged, and the docking manner can be a plug-in fit, for example, the charging connector 13 adopts a charging gun head or a charging plug, the docking portion 21 adopts a power receiving socket, and the charging gun head or the charging plug extends into the power receiving socket to be charged; the docking method may be contact fitting, and for example, the charging connector 13 is attached to the docking portion 21 and then charged.

Since the power receiving device is not disposed in the middle area of the chassis of the electric vehicle 2 but disposed at the front end or the rear end of the electric vehicle 2, the chassis of the electric vehicle 2 does not need to be modified, and the modification of the electric vehicle 2 is less; for the battery replacement vehicle type, the power receiving device does not occupy the position of the chassis, does not occupy the installation space of the battery, and is favorable for the electric vehicle 2 to expand the battery.

In practical applications, the direction of the docking portion 21 may be set in various ways. An included angle between the orientation direction of the butting portion 21 and the horizontal direction is alpha, and alpha is more than or equal to 0 degrees and less than or equal to 90 degrees; when 0 ° < α < 90 °, the butting portion 21 is directed obliquely downward; when α is 90 degrees, the butting portion 21 faces right below; when α is 0 degrees, the docking portion 21 faces the horizontal direction.

In the case where the abutting portion 21 is provided obliquely downward. If the docking portion 21 is directed to the right below, the electric vehicle 2 can leave after the charging connector 13 of the charging device 1 needs to be separated from the docking portion 21, otherwise the charging connector 13 and/or the docking portion 21 may be damaged. When the docking portion 21 faces obliquely downward, correspondingly, the charging connector 13 needs to face obliquely upward to mate with the docking portion 21, and because the charging connector 13 and the docking portion 21 are arranged obliquely, the electric vehicle 2 is accidentally driven away in the charging process, interference between the charging connector 13 and the power receiving device 21 is avoided, and damage to the charging connector 13 and/or the docking portion 21 is avoided.

In the case where the abutting portion 21 is provided toward the right lower side. This arrangement requires less parking accuracy than the arrangement in which docking unit 21 is oriented obliquely downward, and charging device 1 is more likely to be docked accurately with power reception device 21 of electric vehicle 2.

In the case where the docking portion 21 is disposed in the horizontal direction, the electric vehicle 2 is accidentally driven away during charging, and also the charging connector 13 and/or the docking portion 21 are not damaged.

Further, in one embodiment, the bottom of the vehicle body is provided with a protective cover capable of being opened and closed, and the protective cover can shield the butt joint part 21. Specifically, the protective cover can be articulated with the car body, sliding connection, also can be connected through the buckle. After the protective cover is opened, the docking portion 21 is exposed to the outside and can be docked with the charging connector 13 of the charging device 1; after the protective cover is closed, the protective cover can prevent dust, road surface sewage and the like from contacting the butt joint part 21, so that the butt joint part 21 is protected.

Further, in one embodiment, the powered device of the electric vehicle 2 is located on the left side or the right side of the bottom of the vehicle tail of the electric vehicle 2. Specifically, the oil tanker has an exhaust stack, and the exhaust stack is generally disposed on the left or right side of the bottom rear end of the oil tanker. The electric vehicle 2 is generally improved on the basis of a gasoline engine, an exhaust funnel is eliminated because exhaust is not needed, and the exhaust funnel is in an idle state. The left side or the right side of electric vehicle 2's bottom rear end are located with the power receiving device to this embodiment, install in the position of the former aiutage of oil truck, and is more high-efficient to electric vehicle 2's transformation, and the structural utilization is more reasonable. In addition, compared with the chassis, the vehicle tail is higher from the ground, and the electric vehicle 2 is not easy to cause pollution to the power receiving device when wading, so that the requirement on the protection level of the power receiving device is low.

Further, in one embodiment, the power receiving device is connected with the vehicle body through the flexible member 4 or a driving component, and the driving component is a driving assembly capable of driving the power receiving device to move laterally and/or lift relative to the vehicle body. Since the power receiving device can move relative to the vehicle body by the flexible member 4 or the driving member, the power receiving device can be successfully docked with the charging device 1 even if the parking position of the electric vehicle 2 is inaccurate. It is understood that in other embodiments, the powered device may be fixed to the vehicle body.

Referring to fig. 1 to 22, the charging device 1 provided by the present application is configured to be docked with the power receiving device docking portion 21 of the electric vehicle 2 with the above structure for charging, the charging device 1 includes a supporting base 11, a moving arm 12, a charging connector 13 and a driving mechanism, the supporting base 11 is installed in a parking space and corresponds to the power receiving device of the electric vehicle 2, a first end of the moving arm 12 is disposed on the supporting base 11, the charging connector 13 is connected with a second end of the moving arm 12, and a driving end of the driving mechanism is connected with the moving arm 12.

Specifically, the support base 11 may be specifically disposed on the ground of the parking space, or may be of a buried structure, and is wholly or partially installed below the ground of the parking space. The motion arm 12 can be moved in a rotational (e.g., swinging) manner or in a telescopic manner.

In the working process, a charging instruction is triggered in a manual triggering or automatic detection triggering mode, the driving mechanism drives the moving arm 12 to move according to the charging instruction, the moving state of the moving arm 12 is consistent with the orientation of the butting part 21 of the power receiving device of the electric vehicle 2, and the moving arm 12 drives the charging connecting piece 13 to be butted with the butting part 21 of the power receiving device of the electric vehicle 2.

Further, in one embodiment, the motion arm 12 moves in a swinging and/or telescoping manner.

The telescopic stroke of the moving arm 12 is required to meet the smooth butt joint of the charging connector 13 and the butt joint part 21. The flexible mode can reduce charging device 1's volume, reduces the occupation space of charging device 1 in the parking stall.

It can be understood that the solution that the moving arm 12 is a telescopic arm is suitable for the case that the docking portion 21 is disposed in an oblique downward direction, a direct downward direction, and a horizontal direction, and the telescopic direction of the moving arm 12 is consistent with the specific orientation of the docking portion 21. That is, referring to fig. 1 and 5, when the docking portion 21 is oriented obliquely downward, the charging link 13 is located obliquely downward of the docking portion 21, and the moving arm 12 extends and contracts obliquely upward; referring to fig. 8, when the docking portion 21 faces downward, the charging connector 13 is located right below the docking portion 21, and the moving arm 12 extends and retracts toward upward; referring to fig. 12, when the docking portion 21 is oriented in the horizontal direction, the heights of the charging connector 13 and the docking portion 21 are kept equal, and the moving arm 12 extends and contracts in the horizontal direction.

The moving arm 12 may be of a rod-shaped structure with a non-adjustable length, the first end of the moving arm 12 is hinged to the supporting base 11 through a spherical surface or a hinged shaft, so as to achieve a rotating connection effect, and the spherical center of the spherical surface or the axis of the hinged shaft is the rotating center. When the moving arm 12 swings about the rotation center of the first end, the second end of the moving arm 12 brings the charging link 13 close to and away from the docking portion 21. On the basis of realizing adjusting the position of the charging connecting piece 13, compared with a telescopic structure, the structure of the moving arm 12 can be simplified without being telescopic, and the cost is reduced.

Taking fig. 7 as an example for explanation, in fig. 7, the lower left end of the moving arm 12 is a first end, and the upper right end is a second end, and the moving arm 12 can swing clockwise and counterclockwise around the lower left first end, and drives the charging link 13 to move in the swinging process.

It will be appreciated that the movement of the arm 12 in a swinging motion is also applicable to the case where the docking portion 21 is disposed in an obliquely downward, directly downward, or horizontal direction.

Optionally, in another embodiment, referring to fig. 7, 10, and 11, the moving arm 12 is a telescopic arm, a first end of the moving arm 12 is rotatably connected to the supporting base 11, and the driving mechanism drives the moving arm 12 to swing upward around the rotation center to a second preset position according to the charging command; when the moving arm 12 is located at the second preset position, the docking portion 21 of the power receiving device of the electric vehicle 2 is located in the telescopic direction of the moving arm 12. Specifically, the moving arm 12 can be both telescopic and swingable, and the position of the charging connection member 13 is adjusted by the combined movement of the telescopic movement and the swinging movement.

Taking fig. 7 as an example, in fig. 7, the lower left end of the moving arm 12 is a first end, and the upper right end is a second end, and the moving arm 12 can swing clockwise and counterclockwise around the lower left first end. In addition, the moving arm 12 in the position shown in fig. 7 can also be extended and contracted in an oblique direction, which is a direction from bottom left to top right in fig. 7. The moving arm 12 moves the charging link 13 during swinging and/or telescoping.

It will be appreciated that the movement of the arm 12 by a combination of swinging and extending is also applicable to the case where the docking portion 21 is oriented obliquely downward, directly downward, or horizontally.

Further, in an embodiment, the charging device 1 further includes a parking space 3, the parking space 3 is disposed in a parking area of the electric vehicle 2 and protrudes from the ground, when the electric vehicle 2 moves forward or backward to a proper position, the charging connector 13 is abutted with the abutting portion 21 of the power receiving device of the electric vehicle 2, at this time, the parking space 3 is in contact with a front wheel or a rear wheel of the electric vehicle 2, the wheel collides with the parking space 3, so that the driver feels that the electric vehicle is parked in the proper longitudinal position, and the electric vehicle 2 is prevented from exceeding or not reaching the position of the charging connector 13 at the parking space longitudinal parking position.

The transverse translation mechanism 5 can solve the problem of large deviation of the transverse parking position. The transverse translation mechanism 5 may have a driving part to perform active adjustment of the transverse position, or the transverse translation mechanism 5 may have no driving part to perform passive position adjustment under the driving of the charging connection member 13.

The lateral translation mechanism 5 may be installed between the ground of the parking space and the support base 11, and at this time, the support base 11, the moving arm 12 and the charging connector 13 may be integrally adjusted in lateral position in the parking space. The transverse translation mechanism 5 can also be installed between the support base 11 and the moving arm 12, if the transverse parking position of the electric vehicle 2 has deviation, the transverse translation mechanism 5 can be actively or passively adjusted to drive the moving arm 12 and the charging connecting piece 13 to integrally move transversely, so that the butt joint part 21 is in accurate butt joint with the charging connecting piece 13. The lateral translation mechanism 5 may also be mounted between the moving arm 12 and the charging link 13. If the transverse parking position of the electric vehicle 2 is deviated, the positions of the support base 11 and the moving arm 12 are not changed, and the transverse translation mechanism 5 can be actively or passively adjusted to drive the charging connecting piece 13 to transversely move relative to the moving arm 12, so that the butt joint part 21 is accurately butted with the charging connecting piece 13.
