[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The locking component of an embodiment of the present invention will now be described with reference to the accompanying drawings. Figures 1 to 3 As shown, the locking assembly according to an embodiment of the present invention includes a socket 1, a connector 2, and a coil 3.

[0025] The connector 1 has a socket 11 with its opening facing downwards. At least a portion of the connector 1 is formed by a first magnetically conductive element 12. A connector 2 is inserted upwards into the socket 11, and at least a portion of the connector 2 is formed by a second magnetically conductive element 21. Specifically, both the first magnetically conductive element 12 and the second magnetically conductive element 21 are made of high-permeability materials and are components used to guide and concentrate magnetic field lines, forming a low-resistivity path. For example, the first magnetically conductive element 12 and the second magnetically conductive element 21 can be silicon steel sheets or pure iron. As another example, the wall surface of the first magnetically conductive element 12 forms at least a portion of the wall surface of the socket 11, and the second magnetically conductive element 21 on the connector 2 located within the socket 11 can connect with the first magnetically conductive element 12.

[0026] The coil 3 cooperates with at least one of the first magnetic conductive element 12 and the second magnetic conductive element 21. When the coil 3 is energized, at least one of the first magnetic conductive element 12 and the second magnetic conductive element 21 has magnetic force. Specifically, the coil 3 can be sleeved on the outside of at least one of the first magnetic conductive element 12 and the second magnetic conductive element 21. When the coil 3 is energized, the magnetic circuit is closed, which allows at least one of the first magnetic conductive element 12 and the second magnetic conductive element 21 to be magnetized, so that the first magnetic conductive element 12 and the second magnetic conductive element 21 can be attracted together, so that the plug socket 1 and the plug 2 can be fixedly connected through the attracted first magnetic conductive element 12 and the second magnetic conductive element 21.

[0027] When the coil 3 is energized, the first magnetic conductor 12 and the second magnetic conductor 21 are attracted together by magnetic force, thus fixing the connector 2 located in the insertion slot 11 inside the connector 1. Specifically, after the connector 2 is inserted upward into the insertion slot 11, the coil 3 is energized, realizing the closure of the magnetic circuit. The first magnetic conductor 12 and the second magnetic conductor 21 are attracted together by magnetic force, so that the connector 2 can overcome gravity and be fixed inside the connector 1 by using magnetic force, thereby realizing the locking of the locking assembly.

[0028] When the coil 3 is de-energized, the connector 2 located in the connector slot 11 is dislodged downwards from the connector 1 under the action of gravity. Specifically, after the coil 3 is de-energized, the magnetic path is broken, and neither the first magnetic conductor 12 nor the second magnetic conductor 21 has magnetic force. The first magnetic conductor 12 and the second magnetic conductor 21 no longer attract each other, so that the connector 2 located in the connector slot 11 falls downwards under the action of gravity to detach from the connector 1, thereby realizing the automatic unlocking of the locking component.

[0029] The locking assembly according to this embodiment of the invention does not have a mechanical limiting / interference structure. Instead, it uses a matching electromagnetic device (coil 3, first magnetic conductor 12, and second magnetic conductor 21) so that when the coil 3 is energized, the connector 1 can use magnetic force to fix the connector 2 inside. When the coil 3 is de-energized, the connector 2 can detach downwards from the connector 1. Therefore, when the locking assembly according to this embodiment of the invention is used to connect other devices, the position of the connector 2 can be controlled by energizing or de-energizing the coil 3 to achieve locking and locking. Alternatively, in case of system malfunction or power failure, when the operator does not need to actively unlock or when unlocking is difficult, the locking assembly can automatically unlock, thus avoiding abnormal locking that would prevent the connector 2 from disconnecting.

[0030] Therefore, the locking component according to the present invention can be easily locked and unlocked, and can be automatically unlocked in the event of a power outage.

[0031] like Figure 1 and Figure 2As shown, in some embodiments, the coil 3 is sleeved on the outside of the first magnetic conductor 12. Specifically, the coil 3 is connected to the connector 1, thereby improving the stability of the coil 3 and reducing the possibility of damage to the coil 3.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the first magnetic conductor 12 includes a first magnetic tube 121 extending in the vertical direction. The inner wall of the first magnetic tube 121 defines the side wall of the insertion slot 11, and the coil 3 is sleeved on the outside of the first magnetic tube 121. Thus, when the coil 3 is energized, the first magnetic tube 121 generates a magnetic force, causing the insertion piece 2 to be attracted by the surrounding first magnetic tube 121, thereby fixing the insertion piece 2 within the slot 11. When the coil 3 is de-energized, the first magnetic tube 121 has no magnetic force, and the insertion piece 2 located in the insertion slot 11 is dislodged downwards from the first magnetic tube 121 under the action of gravity.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, the first magnetic conductor 12 further includes a first magnetic post 122, which fills the upper part of the first magnetic tube 121. The lower surface of the first magnetic post 122 and the inner wall of the first magnetic tube 121 define a insertion slot 11. Thus, when the coil 3 is energized, the first magnetic post 122 generates magnetic force, allowing the insertion piece 2 to be attracted by the upper first magnetic post 122 and the surrounding first magnetic tube 121, further securing the insertion piece 2 within the slot 11. When the coil 3 is de-energized, the first magnetic post 122 has no magnetic force, and the insertion piece 2, located in the insertion slot 11, is dislodged downwards from the first magnetic tube 121 under gravity.

[0034] In some embodiments, the coil 3 is sleeved on the outer side of the upper part of the first magnetic tube 121, and / or, the coil 3 is sleeved on the outer side of the lower part of the first magnetic tube 121. That is, the coil 3 can be sleeved on the outer side of the upper part of the first magnetic tube 121 so that the upper part of the first magnetic tube 121 and the first magnetic post 122 generate a magnetic force, thereby attracting the plug-in 2 (second magnetic component 21). Alternatively, the coil 3 can be sleeved on the outer side of the lower part of the first magnetic tube 121 so that the lower part of the first magnetic tube 121 generates a magnetic force, so as to attract the plug-in (second magnetic component 21) located in the lower part of the first magnetic tube 121. Alternatively, the coil 3 is sleeved on the outer side of the upper part of the first magnetic tube 121, and the coil 3 is sleeved on the outer side of the lower part of the first magnetic tube 121, that is, the coil 3 is sleeved on the outer side of the entire first magnetic tube 121 and the first magnetic post 122, so that both the entire first magnetic tube 121 and the first magnetic post 122 can attract the plug 2 (second magnetic component 21).

[0035] In some embodiments, the first magnetic post 122 and the first magnetic tube 121 are integrally formed to ensure high stability of the connector 1.

[0036] In some embodiments, the second magnetic conductor 21 constitutes the (entire) connector 2, and the shape and size of the second magnetic conductor 21 are adapted to the shape and size of the connector slot 11. This allows the second magnetic conductor 21 to be large in size and easily connected to the first magnetic conductor 12, thereby facilitating the first magnetic conductor 12 to magnetically attract the connector 2.

[0037] like Figures 1 to 3 As shown, in some embodiments, the lower surface of the first magnetic post 122 defines a concave conical groove, and the top of the second magnetic element 21 is a conical protrusion 22 that mates with the conical groove. The shape and size of the conical protrusion 22 are adapted to the conical groove so that the first magnetic post 122 can use the conical groove to fix the second magnetic element 21, and the conical protrusion 22 can facilitate the second magnetic element 21 to enter the slot 11.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the insertion slot 11 includes a first cavity 111 and a second cavity 112. The second cavity 112 is located below the first cavity 111, and the diameter of the second cavity 112 is greater than or equal to that of the first cavity 111. The diameter of the second cavity 112 increases downwards, and the diameter of the insertion piece 2 is adapted to the diameter of the first cavity 111. Therefore, during the upward movement of the insertion piece 2, the wall surface of the second cavity 112 can guide the insertion piece 2, thereby facilitating its entry into the first cavity 111.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the outer periphery of the cross-sections of the connector 2, the first cavity 111, and the second cavity 112 are all circular. Specifically, the connector 2 is (generally) cylindrical, the first cavity 111 is a cylindrical cavity, and the second cavity 112 is a frustum-shaped cavity, in order to guide the connector 2 as it moves upward.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the insertion slot 11 further includes a third cavity 113, located above the first cavity 111. The third cavity 113 is a conical cavity, and the top of the insertion piece 2 has a conical protrusion 22 that mates with the conical cavity. The conical protrusion 22 facilitates the insertion piece 2's upward movement to engage with the second cavity 112, allowing it to enter the first cavity 111 of the slot 11. The third cavity 113 can limit the insertion of the insertion piece 2 into the slot 11.

[0041] In some embodiments, the connector 1 has multiple insertion slots 11. Multiple connectors 2 are present, with their bottoms connected to the fixing base 4. Each connector 2 can be inserted into one of the multiple insertion slots 11. Thus, when the coil 3 is energized, the multiple connectors 2 can drive the fixing base 4 to connect securely with the connector 1.

[0042] This utility model also proposes a vehicle charging device, which, according to an embodiment of this utility model, includes a charging socket and a locking component.

[0043] A charging socket is installed on the vehicle and is used to connect to the charging plug 5 of the charging device. The locking assembly is according to an embodiment of the present invention. A connector 1 is installed on the vehicle, and a connector 2 is connected to the charging plug 5. Specifically, when the connector 2 moves upward and inserts into the connector slot 11 of the connector 1, it can drive and guide the charging plug 5 into the charging socket on the vehicle, so that the charging device can charge the vehicle. Then, the coil 3 is energized, thereby fixing the connector 2 to the connector 1 and the charging plug 5 to the charging socket on the vehicle. This avoids abnormal impacts on the connection between the connector 2 and the charging plug 5 caused by changes in vehicle height, allowing the connector 2 and the charging plug 5 to adaptively float. For example, the opening of the charging socket faces downwards, and the charging plug 5 faces upwards. Furthermore, it can automatically unlock after the coil 3 is de-energized, preventing abnormal locking.

[0044] In some embodiments, the socket 1 has multiple insertion slots 11. Multiple insertion members 2 are present, with their bottoms and the charging plug 5 connected to the mounting base 4. Each insertion member 2 can be inserted into one of the multiple insertion slots 11. Since there are multiple insertion slots 11 and multiple insertion members 2, fixing the multiple insertion members 2 within the multiple insertion slots 11 improves the stability of the connection between the charging plug 5 and the charging socket, preventing the charging plug 5 from detaching from the charging socket.

[0045] In some embodiments, the power supply port of the coil 3 is located in the charging socket, and the charging plug 5 has a power supply plug for connecting to the power supply port of the coil 3. Thus, when the charging plug 5 is plugged into the charging socket, the power supply plug on the charging plug 5 inserts into the power supply port of the coil 3 and supplies power to the coil 3, so that the connector 2 is fixed on the connector 1, thereby ensuring a stable connection between the charging plug 5 and the charging socket. After the charging device is powered off, the coil 3 is de-energized to automatically unlock and prevent abnormal locking.
