Examples

As shown in fig. 1-4, the vehicle end charging port assembly of the embodiment comprises a base 1 and a charging port module 2; the base 1 comprises a first body portion 11 and a second body portion 12 connected alternately in a stepped manner, the first body portion 11 having a lateral surface 11a; the charging port modules 2 are connected to the first main body parts 11 in a penetrating way, the number of the charging port modules 2 is at least three, and the at least three charging port modules 2 are respectively arranged on at least two first main body parts 11; at least one of the first body portions 11 is provided with two or more charging port modules 2 at intervals.

Alternatively, the first body portion 11 and the second body portion 12 are other base structures known as the charging port module 2. The first body 11 and the second body 12 are connected to form a step, and the first body 11 and the second body 12 are plate-shaped in the figure. The lateral surface a is a surface facing to the side, the using state of the vehicle end charging port is used as a reference, the lateral surface a faces to an operator, so that the operator can plug the charging gun more easily, and the structure is more friendly for people with small strength to plug the charging gun.

The charging port module 2 is fixedly connected with the first main body 11, preferably is detachably and fixedly connected, including but not limited to bolting in the figure, and also can be a detachable connection structure which is known to tend to be stable and reliable, such as clamping, so as to ensure stable connection of the charging port module 2 in the vehicle situation process, and simultaneously facilitate maintenance and replacement of the charging port module 2 in the later period. More than two charging port modules 2 are arranged on one first main body part 11, so that the space of the base 1 is conveniently and fully utilized, and the number of steps of the base 1 is reduced.

The vehicle end charging port assembly provided with more than three charging port modules 2 is strong in robustness, and even if one of the charging units fails, the charging time is prolonged, but the basic charging function is not affected.

The charging port module 2 can select a national standard device charging socket, and a charging gun plug connected with the charging socket is a national standard direct current interface charging plug. The national standard direct current interface charging plug and the charging socket comprise the following interfaces: the direct current power supply positive and negative interfaces of the battery are connected, the protection grounding interface of the power supply equipment bottom line and the vehicle electric platform is connected, the charging communication interface of the non-vehicle-mounted charger and the electric vehicle communication line is connected, the charging connection confirmation interface is connected, and the low-voltage auxiliary power supply positive and negative interfaces of the low-voltage auxiliary power supply provided by the non-vehicle-mounted charger for the electric vehicle are connected.

Because the charging voltage of the charging gun is constant, the direct current quick charging can be performed by adopting a hybrid connection mode to increase the charging speed and the charging quantity. Taking the direct current charging gun current as 225A, the voltage of 750V, and the parallel charging of six charging port modules 2 and the simultaneous connection of the charging gun as an example, the charging power is 1.01Mw, the megawatt charging capability is primarily realized, and for a 282kwh vehicle-end battery box, 15 minutes full charge (SOC from 5% to 95%) can be realized.

As shown in fig. 1-2, in another embodiment, an electromagnetic shield 3 is provided between the charging port modules 2 of the same first body portion 11. Each socket has a large current of 200A or more passing therethrough, and the electromagnetic shield 3 is used to ensure electromagnetic safety. The electromagnetic shielding device can be specifically selected from conductive rubber, conductive foam, metal EMI, wave-absorbing material, conductive complexing agent and other materials, or the combination of more than two electromagnetic shielding material structural members. Optionally, the electromagnetic shielding device is plate-shaped in the figure or is a cylindrical structure surrounding the outer periphery of the charging port module 2, and optionally surrounding the outer periphery of one or two charging port modules 2. The electromagnetic shielding device in the figure has lower cost. The electromagnetic shielding device is arranged on the peripheries of the two sockets of the same first main body part 11, so that double shielding can be realized, and the shielding effect is better.

As shown in fig. 1-2, in another embodiment, the charging port module 2 has opposite plug connection ends 21 and vehicle-end harness connection ends 22, and the vehicle-end harness connection ends 22 are disposed on the same side of the first main body portion 11 as the electromagnetic shield 3. The plug connection end 21 is connected with the charging gun and is usually arranged in a concave part with a covering part on the surface of the vehicle body; the vehicle-end harness connection end 22 is connected to a harness of an electric vehicle. The electromagnetic shield 3 is mainly used for shielding mutual electromagnetic interference between the vehicle end wire harness connecting end 22 and the wire harness in the vehicle.

As shown in fig. 4, in another embodiment, the electromagnetic shield 3 has a first mounting surface 31 and a second mounting surface 32 intersecting each other, the first mounting surface 31 being sealingly connected to the first main body portion 11, and the second mounting surface 32 being sealingly connected to the second main body portion 12. In the drawing, the electromagnetic shield 3 has a rectangular outer contour, and has a pair of first plate-thickness side surfaces and second plate-thickness side surfaces, the first mounting surface 31 being a first plate-thickness side surface, and the second mounting surface 32 being a second plate-thickness side surface. In the figure, the electromagnetic shielding pieces 3 corresponding to the three steps can be fixedly connected (including integral connection) or can be arranged in a split type mutually independent way.

The number of charging port modules 2 is specifically determined according to the fast charging requirements, while the influence on the battery life needs to be considered in combination, and specifically three, four, five, six or more may be selected.

As shown in fig. 2, in another embodiment, the number of the charging port modules 2 is six, and each first body portion 11 is provided with two or more charging port modules 2. Instead of a relatively long charging time, the number of charging port modules 2 may be four.

In another embodiment, as shown in fig. 5, the vehicle end charging port assembly further includes a display component 4, where the display component 4 is connected with the base 1, and the display component 4 is used to display the working state of the charging port module 2. The display component 4 displays whether the charging connection is normal or visualizes parameters such as the charging quantity. The display assembly 4 may be selected from an indicator light, a breathing light belt, etc. For example, when the charging connection is normal, a green light is displayed; when the initial plug-in electrical connection of the charging is abnormal or the charging is abnormal, the display lamp is in a non-luminous state or a red lamp is displayed.

As shown in fig. 5, in another embodiment, the charging port module 2 and the corresponding display assembly 4 are disposed on the same first main body 11. By "corresponding" is meant that there is an association of charging port modules 2 with display elements 4, optionally one-to-one, or one charging port module 2 corresponds to multiple display elements 4, e.g., more than two display elements 4 displaying different parameters. Alternatively, the display assembly 4 is integrally provided to one first body portion 11.

Taking one charging port module 2 corresponding to one display component 4 as an example: the charging port modules 2 and the corresponding display assemblies 4 are arranged on the same first main body part 11, namely, the display assemblies 4 are arranged on adjacent sides of the charging port modules 2, and the display assemblies 4 in one-to-one correspondence are arranged on the same sides of the corresponding charging port modules 2 so as to prompt the operators to associate the charging port modules 2 with the display assemblies 4.

The display components 4 are integrally disposed on one first main body 11, for example, the arrangement mode of the display components 4 is consistent with the arrangement mode of the charging port modules 2 in the base 1, for example, six display components 4 are arranged in a rectangular array of 3*2 on the same first main body 11, which is also beneficial to prompting the association of two components of an operator. In fig. 1, three first main body portions 11 on the base 1 are sequentially distributed along the up-down direction, and when the first main body portion 11 of the top layer is located at the outer side close to an operator, the first main body portion 11 of the bottom layer is far away from the operator, when the vehicle end charging port assembly is arranged at a lower position of the vehicle body, the first main body portion 11 display unit of the bottom layer can be shielded by an upper layer step, so that six display assemblies 4 are more preferably arranged on the same first main body portion 11, the operator is prevented from bending over, squatting or bending over to view the display assemblies, and the charging experience is improved.

In another embodiment, as shown in fig. 3, the charging port module 2 includes a jack cover 23, the jack cover 23 being removably connected with the plug connection end 21 of the receptacle. The one-to-one connection of the sockets and the socket cover 23 facilitates the targeted protection of the corresponding socket from charging. Alternatively, the outlets connected to the same first body portion 11 share one outlet cover 23, so that the number of times of opening and closing the outlet cover 23 in a single charge can be reduced. The socket cover 23 is shown in hinged connection with the socket.

As shown in fig. 3, in some possible embodiments, a lock 5 is provided between the plug cover 23 and the base 1 or the charging port module 2.
