Detailed Description

As for the background art, the structural design of the charging port of the existing new energy automobile has unreasonable points.

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic view of a charging port of a new energy vehicle according to an embodiment of the present invention; fig. 2 is an internal structural view of the charging port shown in fig. 1. In practical application, the charging port 1 structure shown in fig. 1 is exposed outside a body shell of a new energy automobile and is visible to a user; the internal structure of the charging port 1 shown in fig. 2 is hidden inside the new energy automobile and is not visible to the user.

Specifically, the new energy vehicle may include an electric vehicle, a hybrid vehicle, a fuel cell electric vehicle, and the like that can be driven at least by a battery.

The electric power of the storage battery is provided by an external power supply device, the new energy automobile is provided with a charging port 1, and an external charging connector supplies power to the storage battery through the charging port 1. The charging connector may also be referred to as a charging gun.

In one implementation, the charging port 1 may be a receiving portion formed by recessing a body shell of the new energy automobile towards the inside of the automobile so as to receive a charging socket (also called a charging seat, such as the first socket 11 and the second socket 12 shown in fig. 1 and 2). The charging port 1 includes a cover body (not shown) hinged to the charging port 1 to open or close the charging port 1. When the charging port 1 is closed by the cover body, all parts of the charging port 1 are completely covered, so that the overall appearance of the new energy automobile is concise and attractive; when the charging port 1 is opened, the first socket 11, the second socket 12 and other components are exposed, so that the charging connector and the charging socket are electrically connected.

Specifically, the charging port 1 may have opposite first and second ends 1a and 1b, and the cover body is hinged to the first end 1a of the charging port 1 by a hinge shaft 16.

Further, a latch portion 17 is provided at a second end 1b of the charging port 1, a coupling portion (not shown) is provided opposite to the cover, and the latch portion 17 is coupled to the coupling portion when the cover closes the charging port 1, so as to hold the cover at a position where the charging port 1 is closed.

For example, the latch 17 may include a retractable pin 171, the pin 171 in an extended state being coupled to the coupling, and the pin 171 in a retracted state being separated from the coupling.

Further, the extending and retracting direction of the pin 171 may be parallel to the direction (i.e., the first direction, marked with the x direction in the figure) in which the first end 1a of the charging port 1 points to the second end 1b thereof. Further, the latch 17 may further include a second driving portion 172. One end of the pin 171 is fixed to a sidewall of the second end 1b of the charging port 1, and the opposite end of the pin 171 is movable in a direction toward or away from the first end 1a of the charging port 1 by the second driving part 172.

In one implementation, with continued reference to fig. 1 and 2, the charging port 1 of the new energy vehicle according to this embodiment may include a first socket 11 electrically connected to a storage battery (not shown) of the new energy vehicle, for supplying the direct current from a charging connector (not shown) to the storage battery. For example, the first receptacle 11 may be regarded as a dc charging port.

Specifically, the first socket 11 may be provided with a first socket cover 111, and the first socket cover 111 may be hinged to one side of the first socket 11 and may open or close the first socket 11. Therefore, when the first socket 11 is not needed to be used for charging at ordinary times, the first socket cover 111 closes the first socket 11 to play roles of protection, dust prevention and the like; when the first socket 11 needs to be used, the locking means of the first socket cover 111 and the first socket 11 may be unlocked to open the first socket 11.

In one implementation, with continued reference to fig. 1 and 2, the charging port 1 may further include a second socket 12 connected to an on-board charger (not shown) for transmitting the ac power from the charging connector to the on-board charger for conversion and storage in the battery. For example, the second receptacle 12 may be considered an ac charging port. The vehicle-mounted charger can play a role in alternating current-direct current conversion and can also play a role in rectification.

Specifically, the second socket 12 may be provided with a second socket cover 122, and the second socket cover 122 may be hinged to a side of the second socket 12 and may open or close the second socket 12. Therefore, when the second socket 12 is not needed to be used for charging at ordinary times, the second socket cover 122 closes the second socket 12 to play roles of protection, dust prevention and the like; when the second socket 12 needs to be used, the locking means of the second socket cover 122 and the second socket 12 may be unlocked to open the second socket 12.

Further, the second receptacle 12 may have an adapting portion 123 and the charging connector has an opposite engaging portion (not shown). When the charging connector is inserted into the second socket 12, the fitting portion 123 is engaged with the engaging portion to perform an alignment function, and after the charging connector is inserted into the second socket 12, the fitting portion 123 is coupled with the engaging portion to perform a locking function.

Further, the moving direction of the first socket cover 111 to open the first socket 11 may be the same as the moving direction of the second socket cover 122 to open the second socket 12. For example, in fig. 1, the two socket covers are moved leftward by the illustrated angle to open the respective sockets.

Alternatively, the moving direction of the first socket cover 111 to open the first socket 11 may be different from the moving direction of the second socket cover 122 to open the second socket 12.

For convenience of description, the direction in which the first receptacle 11 is directed toward the second receptacle 12 will be referred to as a first direction, and is denoted by the x direction in the drawing. The direction perpendicular to the first direction is denoted as the second direction, and is denoted as the z direction in the figure. The first socket 11 and the second socket 12 may be arranged side by side substantially along the x-direction, and thus, a direction in which the first socket 11 points toward the second socket 12 is parallel to a direction in which the first end 1a of the charging port 1 points toward the second end 1b thereof.

In one implementation, with continued reference to fig. 1 and 2, the charging port 1 may further include a locking portion 13 for locking the charging connector when the charging connector is electrically connected with the second receptacle 12.

Specifically, the surface of the charging port 1 may be opened with an opening 121 near the second receptacle 12, and the opening 121 communicates with the inside of the new energy vehicle. Further, the locking portion 13 may include a thimble 131, and the thimble 131 is disposed inside the new energy vehicle, and may protrude from the surface of the charging port 1 through the opening 121 and be coupled to the charging connector. The thimble can also be retracted back into the charging port 1 (i.e. inside the new energy automobile) through the opening 121 to decouple from the charging connector.

For example, the thimble 131 may be a push rod having a hook at a distal end thereof. The thimble 131 is normally retracted inside the charging port 1, and when the charging connector is inserted into the second socket 12 and the matching portion 123 is coupled with the engaging portion, the thimble 131 extends out of the opening 121 and hooks the charging connector, so as to perform a double locking function.

Further, the locking portion 13 may further include a first driving portion 132 for driving the thimble 131 to extend out of the opening 121 or to retract back into the charging port 1.

For example, the locking portion 13 may be an electronic lock.

In one implementation, the charging port 1 may further include a control module (not shown) electrically connected to the locking portion 13 to control the locking portion 13 to lock or unlock the charging connector.

Specifically, the control module may be a vehicle control unit of the new energy vehicle.

For example, when the charging connector is inserted into the second socket 12 and the adapter 123 is coupled with the engaging part, the control module recognizes that the charging connector is successfully connected with the second socket 12, and then the control module sends a locking signal to the first driving part 132 through the wire harness. In response to receiving the lock signal, the first driving part 132 drives the thimble 131 to protrude out of the opening 121 to lock the charging connector.

In one implementation, with continued reference to fig. 1 and 2, the charging port 1 may further include an unlocking portion 14 for unlocking the charging connector by the locking portion 13.

Specifically, the unlocking portion 14 may include an unlocking button 141. When the cover opens the charging port 1, the unlock button 141 is exposed and visible to the user. The user can operate the unlock button 141 to issue an unlock signal.

Further, an unlock button 141 may be electrically connected to the control module to send an unlock signal to the control module. For example, in response to a user operation, the unlock button 141 generates an unlock signal and transmits it to the control module through the wire harness to instruct unlocking of the charging connector by the lock portion 13.

In response to receiving the unlocking signal, the control module generates an unlocking instruction and transmits the unlocking instruction to the locking part 13 through the wiring harness. The locking portion 13 controls the first driving portion 132 to move to drive the thimble 131 to retract back into the charging port 1. At this time, the second socket 12 and the charging connector are unlocked, and the user can pull out the charging connector from the second socket 12 by manually decoupling the adapter 123 and the engaging portion.

In a variation, the unlocking unit 14 may be a touch key, a non-touch control, or the like, which can transmit the unlocking requirement of the user to the control module, and those skilled in the art may set the unlocking requirement as needed in practical application, which is not described herein.

In one implementation, with continued reference to fig. 1 and 2, charging port 1 may also include a charge indicator 15 for indicating the state of charge of the battery.

In particular, the charge indicator 15 may comprise indicator lights, the different states of which are used to indicate different states of charge. For example, the indicator light may turn on green during charging of the charging connector through the second receptacle 12. For another example, if the indicator lamp blinks during charging, a charging failure is indicated. For another example, if the charging is finished (if the battery is full), the indicator light is turned off.

Further, the control module may be electrically connected with the charge indicator 15 to control the charge indicator 15 to indicate the state of charge of the battery. For example, during charging, the control module controls the charge indicator 15 to indicate the state of charge in real time according to the real-time charge of the battery.

In one implementation, charge indicator 15 and unlocking portion 14 may be a pre-assembled component. For example, the charge indicator 15 and the unlocking part 14 may be mounted on the same holder 18 and mounted inside the charging port 1 through the holder 18.

Further, the wiring harness of the charge indicator 15 and the unlocking part 14 can be led out through the fixing frame 18 and connected to the control module.

In one implementation, the unlocking portion 14 and the charge indicator 15 may be disposed in an empty area of the charging port 1. Here, the vacant area may refer to a vacant area of the charging port 1 except for the first socket 11, the second socket 12, and the locking part 13. Therefore, all the spaces of the charging port 1 are reasonably utilized, and the arrangement of all parts of the charging port 1 is more compact.

Further, the area where the charge indicator 15 and the unlocking part 14 are located may not be on the same plane as the area where the first socket 11 and the second socket 12 are located.

For example, the area of the charge indicator 15 and the unlocking part 14 may protrude further outward than the area of the first socket 11 and the second socket 12. Therefore, more internal space of the new energy automobile can be saved so as to install other parts of the new energy automobile. That is, the housing portion forming the charging port 1 may have a boss on which the charge indicator 15 and the unlocking portion 14 are provided.

In one implementation, with continued reference to fig. 1 and 2, the charge indicator 15 and the unlocking portion 14 may be disposed side by side on a side of the second socket 12 remote from the first socket 11.

Specifically, the charge indicator 15 and the unlocking portion 14 may be provided at the second end 1b of the charging port 1. Thus, the charge indicator 15 and the unlocking part 14 are disposed away from the hinge shaft 16, and even if the cover does not fully open the charging port 1, the charge indicator 15 and the unlocking part 14 can be fully exposed to the outside, facilitating the user's operation.

Further, the direction of the charge indicator 15 pointing towards the unlocking portion 14 may be perpendicular to the direction of the first socket 11 pointing towards the second socket 12. That is, charge indicator 15 and unlocking portion 14 may be arranged side-by-side in a second direction (i.e., the illustrated z-direction). Thereby, the width of the charging port 1 in the x direction can be minimized.

In one implementation, charge indicator 15 and unlocking portion 14 may be located between second receptacle 12 and latch 17.

Specifically, in the x direction shown in the drawing, a hinge shaft 16, a first socket 11, a second socket 12, a charge indicator 15, an unlocking portion 14, and a latch 17 may be provided in this order from a first end 1a of the charging port 1 to a second end 1b thereof. Thereby, the height of the charging port 1 in the z direction can be minimized.

Further, the unlocking portion 14 and the locking portion 17 are not aligned in the x direction, so as to prevent the pin 171 in the extended state from interfering with the unlocking button 141 protruding from the surface of the charging port 1.

Further, charge indicator 15 and latch 17 may be collinear along the x-direction. Since the indicator lamp has a small volume and a limited height protruding from the surface of the charging port 1, the indicator lamp does not substantially interfere with the pin 171 in the extended state even if the indicator lamp is aligned with the locking portion 17.

Therefore, the unlocking part 14 is arranged to avoid the buckling part 17, so that the structure of each part of the charging port 1 is more compact, and the area of the charging port 1 is favorably minimized. Further, the design of the unlocking portion 14 to escape from the latching portion 17 enables the user to operate the unlocking portion 14 more conveniently without being obstructed by other members (such as the latching portion 17) of the charging port 1.

In one embodiment, to further reduce the length of charging port 1 in the x-direction, at least a portion of pin 171 in the extended state may be aligned with unlocking portion 14 and charge indicator 15 in the z-direction. That is, at least a portion of the unlock button 141, the charge indicator 15, and the pin 171 in an extended state are in order from top to bottom in the z-direction.

Alternatively, at least a portion of the pin 171 in the extended state may be located between the unlock button 141 and the charge indicator 15 along the z-direction.

In a variation, the charge indicator 15 and the unlocking part 14 may be dispersedly disposed at different vacant regions of the charge port 1 to more effectively utilize the vacant space of the charge port 1.

By last, adopt this embodiment, can provide an improved car mouth structure that charges, realize the locking of rifle that charges and remove locking and the real-time instruction of charged state, make 1 area minimization of mouth that charges through compact design when facilitating the user operation, do benefit to the whole pleasing to the eye degree that improves the car.

Specifically, when the charging connector is inserted into and electrically connected to the second socket 12, the locking portion 13 locks the charging connector at the current position to prevent the charging connector from being accidentally detached from the second socket 12 during charging. Further, the unlocking portion 14 is used to trigger the locking portion 13 to unlock the charging connector so that the charging connector can be pulled out from the second receptacle 12. Further, the charge indicator plays a role of indicating the charge state so that the user can accurately know the charge progress of the automobile.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present invention, and the scope of the present invention is defined by the appended claims.
