[0029] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0030] In order to solve the problem of loose connection of vehicle-to-vehicle charging connectors in the prior art, the present application provides a charging connector device.

[0031] like Figures 1 to 5As shown, the charging connector device in the present application includes a first connector body 10, a second connector body 20, at least one adsorption component and at least one snap-on component 40. The first connector body 10 has a first connection end 11; the second connector body 20 has a second connection end 21 that matches the first connection end 11, and at least a portion of one of the first connection end 11 and the second connection end 21 can be inserted into or withdrawn from the other; the adsorption component includes two adsorption members 30, and the two adsorption members 30 in each adsorption component are respectively arranged on two walls opposite to the first connection end 11 and the second connection end 21. When the first connection end 11 and the second connection end 21 are plugged in, the two adsorption members 30 in the adsorption component are adsorbed and matched; one of the first connection end 11 and the second connection end 21 has a snap-on component 40, and the other has a snap-on structure 50 that matches the snap-on component 40, and at least a portion of the snap-on component 40 can enter or withdraw from the snap-on structure 50.

[0032] When using the charging connector device in the present application, the first connector body 10 and the second connector body 20 are respectively arranged on the power supply vehicle and the charging vehicle, and after the first connector body 10 and the second connector body 20 are plugged into each other, the power supply vehicle can charge the charging vehicle through the charging connector device. At the same time, since the present application also has an adsorption component and a snap-on component 40, the adsorption component can ensure that the first connection end 11 and the second connection end 21 are plugged into place during the plugging process of the first connection end 11 and the second connection end 21, and after the first connection end 11 and the second connection end 21 are plugged into place, the first connection end 11 and the second connection end 21 are kept in the plugged state through the mutual cooperation of the snap-on component 40 and the snap-on structure 50, thereby ensuring a stable electrical connection between the power supply vehicle and the charging vehicle. Therefore, the charging connector device in the present application effectively solves the problem of loose connection of the vehicle-to-vehicle charging connector in the prior art.

[0033] Of course, in the present application, the charging vehicle and the power supply vehicle can be electrically connected to the corresponding first connector body 10 and second connector body 20 through wires, thereby ensuring that the power supply vehicle can charge the charging vehicle within a certain distance range.

[0034] In a specific embodiment of the present application, at least a portion of the second connection end 21 can be inserted into or withdrawn from the first connection end 11, and the portion of the second connection end 21 inserted into the first connection end 11 has a snap-on structure 50, and the first connection end 11 has a snap-on assembly 40. In the following embodiments of the present application, the description is based on the situation where the second connection end 21 is inserted into the first connection end 11. Of course, according to actual usage, the specific structures of the first connection end 11 and the second connection end 21 can also be changed so that the first connection end 11 can be inserted into or withdrawn from the second connection end 21, or the specific structures and settings of the first connection end 11 and the second connection end 21 can be interchanged. In addition, in the following embodiments, the second connector body 20 is arranged on the power supply vehicle, and the first connector body 10 is arranged on the charging vehicle.

[0035] Specifically, at least one clamping structure 50 is respectively disposed on a group of oppositely disposed side walls of the second connection end 21, and at least one clamped component 40 is disposed on the first connection end 11, and the clamping structure 50 is disposed in one-to-one correspondence with the clamping component 40. Through such an arrangement, after the second connection end 21 is inserted into the first connection end 11, the stability of the connection between the first connection end 11 and the second connection end 21 can be further ensured, thereby preventing the first connection end 11 from being separated from the second connection end 21.

[0036] Optionally, the clamping structure 50 and the adsorption member 30 are respectively arranged on different walls of the second connection end 21. This arrangement can effectively avoid mutual interference between the adsorption member 30 and the clamping assembly 40, thereby effectively ensuring the stability of the charging connector device.

[0037] In a specific embodiment of the present application, Figures 3 to 5As shown, the snap-fit ​​structure 50 is a snap-fit ​​groove provided on the second connection end 21, and an adsorption portion is provided inside the snap-fit ​​groove. When the second connection end 21 is inserted into place, at least a portion of the snap-fit ​​assembly 40 can be adsorbed by the adsorption portion and enter the snap-fit ​​groove. Preferably, the adsorption portion includes an electromagnet, and the snap-fit ​​assembly 40 includes a magnetic member 41 and a reset member 42. The two ends of the reset member 42 are respectively connected to the magnetic member 41 and the first connection end 11. When the electromagnet is powered on, at least a portion of the magnetic member 41 can be adsorbed by the electromagnet and enter the snap-fit ​​groove. When the electromagnet is powered off, at least a portion of the magnetic member 41 can exit the snap-fit ​​groove under the action of the reset member 42. By such a configuration, when the second connection end 21 is inserted into place, the snap-fit ​​groove can correspond to the magnetic member, and when the electromagnet is powered on, the magnetic member 41 can be adsorbed, so that the magnetic member 41 can enter the snap-fit ​​groove, and then the snap-fit ​​of the first connection end 11 and the second connection end 21 can be achieved, so that the first connection end 11 and the second connection end 21 remain in a plugged state. Furthermore, when the plug-in state between the first connection end 11 and the second connection end 21 needs to be released, the electromagnet can be powered off so that the magnetic member 41 can be withdrawn from the engaging groove under the action of the reset member 42, thereby ensuring that the second connection end 21 can be smoothly withdrawn from the first connection end 11.

[0038] Preferably, the electromagnet is arranged at the bottom of the clamping groove, so that the electromagnet can more easily adsorb the magnetic member 41.

[0039] Optionally, the reset member 42 is an elastic member, such as a spring.

[0040] Specifically, the first connection end 11 is provided with a slot corresponding to the second connection end 21, and at least a portion of the second connection end 21 can be inserted into or withdrawn from the slot, and the slot is provided with a receiving slot capable of receiving the snap-fit ​​assembly 40, and at least a portion of the snap-fit ​​assembly 40 can extend out of the receiving slot. This arrangement ensures that the second connection end 21 will not be interfered by the snap-fit ​​assembly 40 during insertion into the slot, thereby ensuring that the second connection end 21 can be inserted into the slot more smoothly. Accordingly, the snap-fit ​​assembly 40 and the adsorption assembly are respectively provided on different inner side walls of the slot.

[0041] Alternatively, if Figure 1 and Figure 2 As shown, the second connection end 21 is a tapered structure whose cross-sectional area gradually decreases toward the first connection end, and the slot is a tapered groove that cooperates with the tapered structure. In a specific embodiment of the present application, the tapered structure can be a trapezoidal table, and the tapered groove can be a trapezoidal groove. Of course, in the present application, the tapered structure and the tapered groove can also be set to other mutually matching shapes, such as a truncated table, etc.

[0042] Optionally, the bottom of the slot has a charging interface, and the part where the second connection end 21 is inserted into the slot corresponds to the charging interface and is provided with a charging plug. When the second connection end 21 is plugged into place with the first connection end 11, the charging plug is inserted into the charging interface so that the power supply vehicle can charge the charging vehicle.

[0043] Optionally, the adsorption component 30 is a magnetic patch, and the magnetic poles of the two magnetic patches in each adsorption component are opposite. In other words, the magnetic poles of the two magnetic patches close to each other are opposite, so that when the second connection end 21 is inserted into the first connection end 11, the two magnetic patches attract each other to ensure that the second connection end 21 is inserted into place, thereby ensuring that the second connection end 21 and the first connection end 11 can be plugged in more accurately.

[0045] 1. Effectively solve the problem of loose connection of vehicle-to-vehicle charging connector in the prior art;
