In the charging process, the power frequency alternating current of the power grid is used as an energy supply source, the power frequency alternating current is rectified and inverted by the second control device 31 to form high-frequency alternating current, and then the high-frequency alternating current is converted into a magnetic field by the electric energy transmitting platform 32. The power receiving platform 22 generates an induced current in the magnetic field, and then converts the induced current into a direct current by the first control device 21 to charge the battery 41 of the vehicle 4.

It should be noted that, during the charging process, the power receiving platform 22 and the power transmitting platform 32 may be spaced apart from each other or may be abutted to each other, which is not limited in this application.

Referring to fig. 2 and 3, the present application also provides a Vehicle 4, wherein the Vehicle 4 may be, but is not limited to, a sedan, a multi-Purpose Vehicle (MPV), a Sport Utility Vehicle (SUV), an Off-Road Vehicle (ORV), a pickup truck, a minibus, a passenger car, a truck, etc.

The vehicle 4 includes a battery 41 and a power receiving device 2, and the power receiving device 2 includes a power receiving platform 22 described in any of the following embodiments. The battery 41 is electrically connected to the power receiving device 2. Specific charging principles may be referred to as described in the above embodiments. The above-mentioned electric energy transmitting device 3 is installed on the ground of the garage (or parking space), when the vehicle 4 needs to be charged, it is driven into the garage, and the electric energy receiving platform 22 installed on the chassis is aligned with the electric energy transmitting platform 32, and then the charging is started, as shown in fig. 4.

In one embodiment, referring to fig. 5, the power receiving platform 22 is disposed adjacent to a head X1 of the vehicle 4, and the vehicle 4 enters the garage by forward driving for charging.

In another embodiment, referring to fig. 6, the power receiving platform 22 is disposed adjacent to a rear X2 of the vehicle 4, and the vehicle 4 enters the garage by traveling backwards to be charged.

Wherein the X-axis is parallel to the length direction of the vehicle 4, the Y-axis is parallel to the width direction of the vehicle 4, and the Z-axis is parallel to the height direction of the vehicle 4. The power transmitting platform 32, the power receiving platform 22 and the vehicle 4 share the same rectangular coordinate system. Hereinafter, the positive direction of the X axis refers to the direction indicated by the arrow of the X axis, the negative direction of the X axis refers to the direction opposite to the positive direction of the X axis, and the positive and negative directions of the remaining Y axis and Z axis are the same, which are not repeated herein.

Referring to fig. 7, the present application further provides an electric energy receiving platform 22, wherein the electric energy receiving platform 22 is used for charging a battery 41 of the vehicle 4. The power receiving platform 22 has a mounting side a for connecting to the chassis of the vehicle 4 and a charging side B for facing the power transmitting platform 32 for charging.

The power receiving platform 22 includes a receiving device 110 and a housing 120. Wherein the receiving means 110 is adapted to receive electrical energy from the electrical energy transmitting platform 32 and to transfer the electrical energy to the battery 41 of the vehicle 4. The housing 120 includes a receiving structure 121 and a cleaning structure 122. The receiving structure 121 is used for receiving the receiving device 110. The cleaning structure 122 is disposed at one side of the accommodating structure 121 and is directly or indirectly connected to the accommodating structure 121, and the drawings related to the present application illustrate the indirect connection. The cleaning structure 122 is used for cleaning foreign matters on the electric energy emission platform 32 during the process of following the vehicle 4. During the charging process, if there is a foreign object (e.g., metal) in the magnetic field generated by the power transmitting platform 32, the charging process will be disturbed. In the embodiment, a cleaning structure 122 is disposed on the power receiving platform 22, and the cleaning structure 122 can clean the foreign matters on the power transmitting platform 32, so as to avoid the influence of the foreign matters on the charging process. Moreover, the cleaning structure 122 is disposed at one side of the accommodating structure 121, so that the cleaning structure 122 moves relative to the power transmitting platform 32 during the traveling of the vehicle 4, thereby cleaning the foreign matters, and an additional power device is not required to drive the cleaning structure 122 to move, thereby saving the electric quantity.

It should be noted that the cleaning structure 122 is located at the front end of the power receiving platform 22, where the direction of the accommodating structure 121 toward the cleaning structure 122 is a forward driving direction (X-axis negative direction) of the vehicle 4 instead of a reverse driving direction, and during the driving process of the vehicle 4, the cleaning structure 122 first cleans the power transmitting platform 32, and then the power receiving platform 22 gradually covers the power transmitting platform 32.

Alternatively, the sweeping structure 122 may be designed to be cylindrical with a central axis parallel to the Y-axis, such that the sweeping structure 122 is in line contact with the power transmitting platform 32, thereby reducing friction therebetween.

Referring to fig. 7, the housing 120 further includes a connecting structure 123 extending from an outer side of the receiving structure 121. The cleaning structure 122 is connected to an end of the connecting structure 123 far away from the accommodating structure 121. It will be appreciated that this configuration may increase the distance between the cleaning structure 122 and the receiving device 110 in the X-axis direction, and the benefits of increasing the distance are described in more detail below.

To explain in a reverse way that the distance between the cleaning structure 122 and the receiving device 110 is small, when a foreign object exists at the farthest end of the power transmitting platform 32 from the power receiving platform 22 during the running of the vehicle 4 facing the power transmitting platform 32, and the vehicle 4 is not in place when the vehicle is stopped, the cleaning structure 122 may not reach the foreign object, and the purpose of removing the foreign object may not be achieved, where the not in place means that the receiving device 110 has not reached the position completely opposite to the power transmitting platform 32, and the vehicle 4 has already stopped running, that is, the vehicle 4 has stopped prematurely. In the embodiment, the connecting structure 123 is disposed between the cleaning structure 122 and the accommodating structure 121, so that the coverage of the whole power receiving platform 22 is increased, the cleaning range of the cleaning structure 122 is also increased, and even if the vehicle 4 is not in place when stopped, the cleaning structure 122 can contact with the foreign matters, so as to remove the foreign matters. It should be noted that the connecting structure 123 and the accommodating structure 121 may be an integral structure or a split structure.

Referring to fig. 8, the connecting structure 123 includes a plurality of connecting bars 1231. The plurality means a number of two or more, and specifically, it may be, but not limited to, 2, 3, 5, 6, 7, 9, 11, or the like. The connecting strips 1231 are disposed on the same side of the accommodating structure 121 and are arranged at intervals. Opposite ends of the connecting strips 1231 are respectively connected to the accommodating structure 121 and the cleaning structure 122. In other words, the plurality of connecting bars 1231 are located between the accommodating structure 121 and the cleaning structure 122. And each connecting strip 1231 interval sets up, says that connection structure 123 is the fretwork form, so set up, both can satisfy the connection requirement of accommodating structure 121 and cleaning structure 122, can reduce the weight of electric energy receiving platform 22 again, and then reduce whole car quality.

Referring to fig. 8 and 9, the connecting structure 123 further includes a plurality of reinforcing ribs 1232. The number of reinforcing ribs 1232 is equal to the number of connecting strips 1231 described above. The plurality of reinforcing ribs 1232 are arranged at intervals. The reinforcing ribs 1232 are connected to the receiving structure 121 and the connecting strips 1231, and different reinforcing ribs 1232 are connected to different connecting strips 1231. It can be understood that since the plurality of connecting strips 1231 are arranged at intervals, the single connecting strip 1231 may be bent or broken, and therefore, the arrangement of the reinforcing rib 1232 can increase the mechanical strength of the connecting strip 1231, thereby ensuring that the cleaning structure 122 can exert its cleaning effect well.

Referring to fig. 2 and 10, the power receiving platform 22 further includes a first auxiliary 130 and a second auxiliary 140. The first auxiliary element 130 and the second auxiliary element 140 are respectively connected to two ends of the sweeping structure 122 in a back-to-back manner. It is understood that when the vehicle 4 stops in the garage, the vehicle 4 may be deviated to the left or to the right in the width direction with respect to the power transmission platform 32. If the length of the cleaning structure 122 is short, when the vehicle 4 is deviated to the right (the power receiving platform 22 is deviated to the positive direction of the Y axis relative to the power transmitting platform 32), the foreign matters on the power transmitting platform 32 positioned at the left side of the cleaning structure 122 cannot be removed; similarly, when the vehicle 4 is deviated to the left (the power receiving platform 22 is deviated toward the negative Y-axis direction relative to the power transmitting platform 32), the foreign objects on the power transmitting platform 32 on the right side of the cleaning structure 122 cannot be removed. The first auxiliary element 130 and the second auxiliary element 140 provided in this embodiment are disposed at both ends of the cleaning structure 122, so that the cleaning range can be enlarged in the Y-axis direction, and even if the vehicle 4 is stopped and has a problem of left or right deviation with respect to the power transmitting platform 32, the foreign matter can be removed.

Alternatively, the extending direction of the first auxiliary 130 is parallel to the arrangement direction of the plurality of connecting strips 1231. The extending direction of the second auxiliary 140 is parallel to the arrangement direction of the plurality of connection bars 1231. The first auxiliary member 130 extends from the sweeping structure 122 in a direction away from the second auxiliary member 140. The second auxiliary member 140 extends from the sweeping structure 122 in a direction away from the first auxiliary member 130. In other words, the first auxiliary element 130 and the second auxiliary element 140 are parallel to the Y axis, and the parallel arrangement can achieve a larger cleaning range with less material in the Y axis direction compared to bending and connecting the first auxiliary element 130 and the second auxiliary element 140 to the cleaning structure 122.

In other embodiments, the first auxiliary element 130 and the cleaning structure 122 may be connected in a bent manner, that is, the first auxiliary element 130 and the cleaning structure 122 form an included angle, the included angle refers to a smallest positive angle formed by the intersection of the first auxiliary element 130 and the cleaning structure 122, and the included angle may be, but is not limited to, 20 °, 35 °, 36 °, 41.3 °, 50 °, 60 °, 72 °, and the like. Similarly, the second auxiliary element 140 and the cleaning structure 122 may be connected in a bent manner, that is, the second auxiliary element 140 and the cleaning structure 122 form an included angle, the included angle is a smallest positive angle formed by the intersection of the second auxiliary element 140 and the cleaning structure 122, and the included angle may be, but is not limited to, 20 °, 35 °, 36 °, 41.3 °, 50 °, 60 °, 72 °, and the like.

Referring to fig. 2 and 10, the power receiving platform 22 further includes a third auxiliary 150 and a fourth auxiliary 160. The third auxiliary 150 and the fourth auxiliary 160 are respectively connected to two ends of the accommodating structure 121 in an opposite manner. The third auxiliary 150 and the fourth auxiliary 160 serve to increase the size of the power receiving stage 22 in the Y-axis direction.

The following describes advantageous effects of the third auxiliary 150 and the fourth auxiliary 160 with reference to the following scenarios: under the condition that the electric energy receiving platform 22 and the electric energy transmitting platform 32 are charged in the abutting mode, if the stopping position of the vehicle 4 is left-biased (the electric energy receiving platform 22 is biased towards the negative direction of the Y axis relative to the electric energy transmitting platform 32) or right-biased (the electric energy receiving platform 22 is biased towards the positive direction of the Y axis relative to the electric energy transmitting platform 32) relative to the electric energy transmitting platform 32, only a part of the electric energy transmitting platform 32 is abutted by the electric energy receiving platform 22, so that one end of the electric energy transmitting platform 32 is stressed, and the other opposite end is not stressed, so that an overturning moment is formed, the electric energy transmitting platform 32 has a rollover tendency, and the electric energy transmitting platform 32 can be damaged after a plurality of actions. In this embodiment, the third auxiliary 150 may increase the size of the power receiving platform 22 in the positive Y-axis direction, and the fourth auxiliary 160 may increase the size of the power receiving platform 22 in the negative Y-axis direction. Regardless of whether the vehicle 4 is deviated left or right, any one of the third auxiliary 150 and the fourth auxiliary 160 may abut on the electric energy launching platform 32, so that a situation where one end of the electric energy launching platform 32 is stressed and the other end is unstressed may be avoided.

Alternatively, the extending direction of the third auxiliary 150 is parallel to the arrangement direction of the plurality of connecting strips 1231. The extending direction of the fourth auxiliary 160 is parallel to the arrangement direction of the plurality of connection bars 1231. The third auxiliary 150 extends from the receiving structure 121 in a direction away from the fourth auxiliary 160. The fourth auxiliary member 160 extends from the receiving structure 121 in a direction away from the third auxiliary member 150.

Of course, in other embodiments, the third auxiliary 150 and the fourth auxiliary 160 may not be parallel to the Y axis, that is, the extending direction of the third auxiliary 150 forms an angle with the extending direction of the cleaning structure 122, the so-called angle is the smallest positive angle formed by the intersection of the third auxiliary 150 and the extending direction of the cleaning structure 122, and the size of the angle may be, but is not limited to, 20 °, 35 °, 36 °, 41.3 °, 50 °, 60 °, 72 °, and the like. Similarly, the extending direction of the third auxiliary 150 forms an angle with the extending direction of the cleaning structure 122, the angle is the smallest positive angle formed by the intersection of the fourth auxiliary 160 and the extending direction of the cleaning structure 122, and the size of the angle may be, but is not limited to, 20 °, 35 °, 36 °, 41.3 °, 50 °, 60 °, 72 °, and the like.

Referring to fig. 9, the accommodating structure 121 includes a top plate 1211, a circumferential portion 1212, and a plurality of fixing portions 1213. The circumferential portion 1212 is bent and connected to the circumferential edge of the top plate 1211. The top plate 1211 may have a rectangular shape, a circular shape, an oval shape, etc., and accordingly, the circumferential portion 1212 may be a rectangular ring, a circular ring, an oval ring, etc. The top 1211 and the circumferential portion 1212 define a housing space. The receiving space is used for accommodating the receiving device 110. The plurality of fixing portions 1213 are connected to the circumferential portion 1212 and arranged at intervals along a circumferential direction of the circumferential portion 1212. The fixing portion 1213 is used to connect to the chassis of the vehicle 4 to fix the power receiving platform 22 to the vehicle 4. The fixing portion 1213 may be provided with a through hole, and then a connector such as a bolt or a screw may be inserted through the through hole to connect the connector to the chassis of the vehicle 4, thereby fixing the power receiving platform 22. In this embodiment, the plurality of fixing portions 1213 are arranged at intervals in the circumferential direction of the circumferential portion 1212, so that the power receiving platform 22 can be fixed on the chassis of the vehicle 4 more firmly, and the force applied to each fixing portion 1213 is more uniform.

Alternatively, the fixing portions 1213 may protrude from the top plate 1211 in a direction (positive direction of the Z axis) in which the receiving device 110 faces the top plate 1211. When the power receiving platform 22 is mounted on the chassis of the vehicle 4, the fixing portion 1213 contacts the chassis with a gap between the top plate 1211 and the chassis. If the top plate 1211 protrudes from the fixing portion 1213 in the positive direction of the Z axis, the top plate 1211 abuts directly against the chassis during the mounting of the power receiving platform 22 on the chassis of the vehicle 4, and there is a gap between the fixing portion 1213 and the chassis, which is disadvantageous for the fixing of the power receiving platform 22 and is not strong after the fixing because the connecting member for connecting the fixing portion 1213 and the chassis is more easily bent. In the present embodiment, the fixing portion 1213 is disposed to protrude from the top plate 1211, so that the fixing portion 1213 can be securely in contact with the chassis of the vehicle 4, and the power receiving platform 22 can be easily mounted and can be more firmly mounted.

Of course, in another embodiment, the highest point of the fixing portion 1213 may be flush with the top plate 1211 in the positive direction of the Z axis.

Optionally, the circumferential portion 1212 protrudes from the receiving device 110 in a direction (negative direction of the Z axis) in which the top plate portion 1211 faces the receiving device 110. In some cases, to improve charging efficiency, the power receiving platform 22 is abutted against the power transmitting platform 32. In the present embodiment, since the circumferential portion 1212 protrudes from the receiving device 110, when the power receiving platform 22 abuts against the power transmitting platform 32, the circumferential portion 1212 abuts against the power transmitting platform 32 instead of the receiving device 110, and it can be understood that this arrangement is favorable for protecting the receiving device 110 from being damaged.

Optionally, the circumferential portion 1212 is flush with the receiving device 110 in a direction (negative direction of Z axis) in which the top plate portion 1211 faces the receiving device 110, so that the receiving device 110 can be closer to the power transmitting platform 32 during charging, thereby improving charging efficiency.

Referring to fig. 8 and 9, the power receiving platform 22 further includes a cover plate 170. The cover plate 170 may be, but not limited to, plastic or other material that does not affect the charging effect. The cover plate 170, the top plate 1211 and the circumferential portion 1212 collectively define the receiving space. The cover plate 170 has an opening 171. The opening 171 communicates with the housing space. The receiving device 110 is exposed from the opening 171. It is understood that exposing the receiving device 110 from the opening 171 can prevent the magnetic field generated by the power transmitting platform 32 from being weakened, thereby ensuring a high charging efficiency of the power transmitting platform 32 and the power receiving platform 22.

Optionally, the opening 171 includes a first opening 1711 and a second opening 1712 which are arranged at intervals. The first opening 1711 has dimensions of 10cm x 10 cm. The area size of the receiving device 110 exposed from the first opening 1711 is 10cm × 10 cm. The second opening 1712 has dimensions of 10cm x 10 cm. The area size of the receiving device 110 exposed from the second opening 1712 is 10cm × 10 cm. In the related art, the area size of the receiving device 110 exposed from the first opening 1711 is 2.5cm × 2.5cm, and the area size of the receiving device 110 exposed from the second opening 1712 is 2.5cm × 2.5cm, and the charging requirement can be satisfied when the area size is set to 2.5cm × 2.5 cm. In the present embodiment, the area size is set to 10cm × 10cm, so that the vehicle 4 may be allowed to have a parking deviation with respect to the electric energy transmission platform 32, that is, even if the vehicle 4 stops in the garage, the receiving device 110 may have a deviation in the X-axis or Y-axis direction with respect to the electric energy transmission platform 32, and the charging requirement may be satisfied.

Referring to fig. 7, the power receiving platform 22 further includes a connector 180. The connector 180 is connected to an end of the receiving structure 121 away from the cleaning structure 122 and is electrically connected to the receiving device 110. The first control device 21 is electrically connected to the receiving means 110 via the connector 180 for transmitting electrical energy.

Although embodiments of the present application have been shown and described, it is understood that the above embodiments are illustrative and not restrictive, and that those skilled in the art may make changes, modifications, substitutions and alterations to the above embodiments without departing from the scope of the present application, and that such changes and modifications are also to be considered as within the scope of the present application.
