Description

Technical Field

[0001] The invention belongs to the field of new energy vehicle charging sockets, and in particular relates to a charging socket dust cover and a charging socket assembly. Background Art

[0002] Most of the new energy vehicles on the market currently have dust covers on their charging sockets to prevent foreign objects from entering the charging sockets. The existing dust covers for charging sockets are generally cover parts formed by soft plastic or integrated injection molding. The structure can refer to the automobile charging socket protective cover disclosed in the Chinese utility model application with the authorization announcement number CN206532952U. This automobile charging socket protective cover generally has a cylindrical side wall. When in use, the cylindrical side wall can be tightly inserted on the inner side of the side wall of the charging port of the charging socket, or tightly wrapped on the outer side of the side wall of the charging port. In the environment of vibration, extreme high temperature or extreme low temperature, this automobile charging socket protective cover is very easy to fall off from the charging port, which causes the charging port to lose its original protection, and it is easy for dust, moisture, and debris to fall into the charging port, which not only affects the service life of the charging port, but also buries safety hazards for the charging operation of the charging port.

[0003] In response to the above problems, the utility model patent with authorization announcement number CN208571053U discloses a protective cover, on which a lock hook as a retaining structure is provided, and a lock hook groove that cooperates with the lock hook is provided on the charging socket. After the protective cover is installed in place, the lock hook and the lock hook groove are hooked and matched to reliably retain the protective cover on the charging socket. The above structure requires designing a lock hook groove on the charging socket that cooperates with the lock hook of the protective cover, that is, it is necessary to change the structure of the charging socket on the existing new energy vehicle. Therefore, this protective cover cannot be directly applied to the existing charging socket of the new energy vehicle. When used, the charging socket of the new energy vehicle must be correspondingly changed, and the cost of use is relatively high. Summary of the invention

[0026] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0027] The scheme principle of the charging socket assembly of the present invention is as follows: A charging socket assembly comprises a charging socket and a charging socket dust cover snapped onto a charging port of the charging socket, wherein the charging socket is provided with an electronic lock for locking a charging gun, and the charging socket dust cover comprises a cover body, the cover body is provided with a buckle cylinder for fixing and buckling on the charging port of the charging socket, and a buckle window for locking and cooperating with a latch of the electronic lock on the charging socket for locking the charging gun is provided on the barrel wall of the buckle cylinder.

[0028] The above structure can use the electronic lock on the existing charging socket for locking the charging gun to lock the dust cover of the charging socket. In this way, on the one hand, the buckle window as a retaining structure can ensure that the dust cover of the charging socket can be reliably locked and retained on the charging socket; on the other hand, there is no need to set an additional structure on the charging socket or make additional structural changes to adapt the dust cover of the charging socket. Therefore, the above structure can effectively reduce the use cost of the dust cover of the charging socket while realizing the reliable locking and retention of the dust cover of the charging socket on the charging socket, thereby reducing the use cost of the entire charging socket assembly.

[0029] Embodiments of the charging socket assembly of the present invention: A charging socket assembly, the structure of which can refer to Figure 1 As shown, it specifically includes a charging socket 1 and a charging socket dust cover 2 buckled on the charging port 3 of the charging socket 1. In this embodiment, the charging socket 1 is specifically an existing European standard charging socket 1, and its structure can be referred to Figure 2 As shown. The charging port 3 of the charging socket 1 includes a power socket 4 and a signal socket 5 arranged in an upper and lower manner. An electronic lock 6 for locking the charging gun is provided on one side of the charging port 3. When charging, the lock latch of the electronic lock 6 can be extended and matched with the lock window lock on the charging gun to completely lock the charging gun on the charging port 3 of the charging socket 1.

[0030] The structure of the charging socket dust cover 2 can be referred to Figure 3 As shown, it includes a cover body 7, and a buckle tube 8 for fixing and buckling on the charging port 3 of the charging socket 1 is provided on the cover body 7. When in use, the buckle tube 8 can be covered on the outside of the charging port 3 of the charging socket 1, or can be plugged on the inside of the charging port 3 of the charging socket 1. A buckle window 9 is opened on the wall of the buckle tube 8. After the dust cover 2 of the charging socket is installed in place, the lock latch of the aforementioned electronic lock 6 extends into the buckle window 9 to lock the dust cover 2 of the charging socket on the charging port 3 of the charging socket 1.

[0031] The key to this example is that there are multiple buckle windows 9 arranged along the circumference of the buckle tube 8. Since the positions of the electronic locks 6 on existing new energy vehicles are different, multiple buckle windows 9 can be arranged along the circumference of the aforementioned buckle tube 8 corresponding to the positions where the electronic locks 6 may be arranged on the new energy vehicles. In this way, no matter which side of the charging socket dust cover 2 the electronic lock 6 is located, the charging socket dust cover 2 can have a matching locking structure adapted thereto. Such a setting can effectively improve the versatility of the charging socket dust cover 2, so that it can adapt to charging sockets 1 with different electronic lock 6 arrangement positions.

[0032] For reference Figure 4 As shown, the aforementioned buckle barrel 8 includes a signal buckle barrel 10 for being buckled on the signal socket 5 of the charging socket 1 separately, and a power buckle barrel 11 for being buckled on the power socket 4 of the charging socket 1 separately. In this embodiment, the cover body 7 is specifically in the shape of a plate, and a button handle 12 is provided on one side of the plate facing outward for user convenience, and a power buckle barrel 11 for being buckled on the power socket 4 of the charging socket 1 separately, and a signal buckle barrel 10 for being buckled on the signal socket 5 of the charging socket 1 separately is provided on the other side of the plate. Such a setting can increase the contact area between the cover body 7 and the charging socket 1, thereby enhancing the connection effect between the cover body 7 and the charging socket 1. In addition, the above structure can respectively prevent dust from the power socket 4 and the signal socket 5, and the dustproof effect is easier to be guaranteed. Of course, the aforementioned buckle barrel 8 can also adopt an integrated design, that is, the aforementioned plate-shaped cover body 7 is provided with an integrated buckle barrel 8, and the shape of the buckle barrel 8 is adapted to the power socket 4 and the signal socket 5 at the same time, so as to be buckled on the power socket 4 and the signal socket 5 at the same time.

[0033] On the basis of the above structure, a short-circuit part 13 can be provided in the barrel cavity of the signal buckle barrel 10. The short-circuit part 13 can short-circuit the PE jack 22 and the PP jack 21 of the charging socket 1 and send a signal that the dust cover 2 of the charging socket is installed in place, so that the latch of the above-mentioned electronic lock 6 can accurately lock with the buckle window 9 on the dust cover 2 of the charging socket. In this way, it can avoid the situation that the latch of the electronic lock 6 and the buckle window 9 are not locked in place, thereby effectively ensuring the locking and holding effect between the dust cover 2 of the charging socket and the charging socket 1. At the same time, the above process does not need to be changed on the original hardware equipment of the new energy vehicle charging socket 1. Only the control system needs to be changed to conveniently realize the in-place recognition of the insertion action of the dust cover 2 of the charging socket. Therefore, the above structure can effectively reduce the use cost of the dust cover 2 of the charging socket while meeting the detection of the dust cover 2 in place of the charging socket.

[0034] The aforementioned short-circuit part 13 includes an identification resistor. With such a setting, the dust cover 2 of the charging socket can be fixedly inserted into the charging port 3 of the charging socket 1 in a manner that simulates the insertion of a charging gun, and the new energy vehicle detects whether the dust cover 2 of the charging socket is in place by detecting whether the charging gun is inserted in place. In this way, by specifically setting the resistance value of the identification resistor, the resistance value on the dust cover 2 of the charging socket can be distinguished from the resistance value of the charging gun, thereby facilitating the control system of the new energy vehicle to distinguish between the charging gun and the dust cover 2 of the charging socket. The control system of the new energy vehicle makes different feedback according to the specific inserted structure of the charging socket 1, so that the use of the new energy vehicle is more closely aligned with the user's usage needs and usage habits.

[0035] For reference Figure 4 As shown, the short-circuit part 13 also includes a pair of electrical contacts, and the aforementioned identification resistor is conductively connected between the paired electrical contacts. This is conducive to conveniently realizing the conductive connection between the short-circuit part 13 and the signal pin on the charging socket 1, and preventing irregular conductive connection from damaging the signal pin in the charging socket 1. In this embodiment, the identification resistor can be installed on a circuit board 15, and the paired electrical contacts are respectively installed on the circuit board 15. The identification resistor can also be directly fixedly connected to the paired electrical contacts; or the identification resistor is first embedded in the cover body 7 as an insert, and the electrical contact is connected to the identification resistor through contact when the electrical contact is installed on the cover body 7. Of course, the aforementioned identification resistor can also be directly fixedly installed on the cover plate, and contacts or contacts for contacting the signal pin on the charging socket 1 are set at both ends of the identification resistor. After the dust cover 2 of the charging socket is inserted into place, the identification resistor directly conducts the signal pin through the contacts or contacts at both ends to achieve short circuit.

[0036] On this basis, a short-circuit protection shell 16 can be provided on the charging socket dust cover 2 to insulate and protect the electrical contacts and the identification resistor. The short-circuit protection shell 16 is provided outside the short-circuit portion 13 and is sealed and fixedly connected to the cover body 7 to prevent electrical leakage from causing harm to the user, and to prevent foreign objects such as debris and dust from falling into the short-circuit portion 13, thereby affecting the connection between the electrical contacts and the identification resistor.

[0037] The aforementioned electrical contact is preferably a socket contact 14 that is compatible with the signal pin in the signal socket 5 of the charging socket 1. Since the contacts on the existing charging socket 1 are generally pin contacts, the aforementioned electrical contact is a socket contact 14, which can ensure that the short-circuit part 13 of the charging socket dust cover 2 and the charging socket 1 have a reliable conductive connection relationship. On this basis, the short-circuit protection shell 16 can specifically include a fixed shell 17 for sealing and fixed connection with the cover body 7 and a cylindrical shell 18 extending in pairs from the shell for accommodating the socket contact 14. In this way, on the one hand, the insulation protection of the socket contact 14 can be reliably guaranteed, and on the other hand, the socket contact 14 and the signal pin can be guided by the cylindrical shell 18. During installation, firstly, the two socket contacts 14 are inserted into the cylindrical shell 18, and then the sealing ring 19 for sealing is installed in the fixed shell 17, and then the electrical contact is connected to the identification resistor. The above-mentioned structure is integrally fixedly mounted on the cover body 7, and the aforementioned sealing ring 19 is sealed between the short-circuit protection shell 16 and the shell. The short-circuit protection shell 16 and the cover body 7 can be fixed by fasteners 20, or they can be welded together by ultrasonic welding. When the latter method is adopted, it is not necessary to set the sealing ring 19, but the sealing between the short-circuit protection cover and the shell can be achieved directly by a sealed weld. Of course, the aforementioned electrical contact can also be a conductive elastic arm, a conductive sheet or a conductive spring, as long as it can short-circuit the signal pins in the PP socket 21 and the PE socket 22 on the charging socket 1.

[0038] A dustproof plug 23 for inserting into the power socket 4 of the charging socket 1 may be provided in the power buckle 11. In this way, during installation, the dustproof plug 23 can cooperate with the power pin in the power socket 4 of the charging socket 1, thereby guiding the short-circuit of the short-circuit part 13 with the PP socket 21 and the PE socket 22. The outer sides of the aforementioned power buckle 11 and the signal buckle 10 are provided with a sealing structure 24 directly injection-molded thereon to ensure the seal between the dust cover 2 of the charging socket and the charging port 3 of the charging socket 1. The sealing structure 24 is obtained by injection molding directly on the outer sides of the power buckle 11 and the signal buckle 10, so that the sealing structure 24 can better adapt to the appearance of the power buckle 11 and the signal buckle 10 to ensure the sealing effect. Of course, the sealing structure 24, the cover body 7, the power buckle 11 and the signal buckle 10 can also be jointly injection-molded by two plastic materials with different hardness. The cover body 7 , the power buckle tube 11 and the signal buckle tube 10 are made of a plastic material with a relatively high hardness, and the sealing structure 24 is made of a plastic material with a relatively low hardness.

[0039] The principle and implementation example of the dust cover for the charging socket of the present invention: The scheme principle and embodiment of the dust cover of the charging socket described in the present invention are consistent with the scheme principle and the charging socket dust cover 2 described in the embodiment of the charging socket assembly described in the present invention, so they are not repeated here.
