Description

Technical Field

[0001] This invention belongs to the field of connection devices, and in particular relates to an automatic dust cover opening and closing structure, a charging socket, and a vehicle. Background Technology

[0002] New energy vehicles typically have a waterproof and dustproof cover on their charging port. The conventional dust cover is inserted into the charging port, and it needs to be manually removed before charging and manually fastened back onto the charging port after charging is complete, which is inconvenient.

[0003] The existing Chinese utility model patent with authorization announcement number CN222355530U discloses a dustproof device for a charging dock. The dustproof device has a cover that can automatically fasten to the charging port under the drive of a torsion spring. Before charging, the cover is manually opened. After the cover is opened to a certain extent, it will be locked in the open position by a locking mechanism. When the charging gun is inserted into the charging port, the unlocking mechanism will be triggered, thereby releasing the locking mechanism from the cover. After the charging gun is pulled out, the cover will automatically fasten.

[0004] The aforementioned dustproof device can only automatically close the dust cover, but not automatically open it, thus its ease of operation is still insufficient. Furthermore, given the current trend towards unmanned and automated charging, the ability to automatically open the dust cover before charging would significantly reduce the technical difficulty of achieving automated charging. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic opening and closing structure for dust covers, so as to solve the technical problem that the dust covers at the charging ports of new energy vehicles in the prior art need to be manually opened and closed by the operator.

The opening component has a load-bearing part. The opening component has an initial blocking position and a flipping avoidance position within its flipping stroke. When it is in the initial blocking position, the load-bearing part is located in front of the charging port and on the insertion and movement path of the charging gun. When it is in the flipping avoidance position, the load-bearing part is pushed over by the charging gun and avoids the charging gun.

At least one of the dust cover and the opening component is provided with an elastic member for transmitting to the dust cover an elastic member that can cause it to rotate so that the cover body is fastened to the charging port and maintain the fastened state.

[0007] As a further improvement, the hinged mounting structure of the dust cover and the opening mechanism is arranged in parallel.

[0008] As a further improvement, the linkage structure consists of a pin on one of the cover opening component and the dust cover, and a fork on the other. The pin is located in the fork, and when one of them is activated, the other is also activated.

[0049] The present invention will be further described in detail below with reference to the embodiments.

[0050] Specific embodiment 1 of the automatic opening and closing structure for the dust cover provided by the present invention: The automatic opening and closing structure of the dust cover can automatically lock onto the charging port 92 and remain locked to prevent dust and rainwater from entering the charging port 92. During the insertion of the charging gun 10 into the charging port 92, the automatic opening and closing structure of the dust cover can automatically open to allow the charging gun 10 to be inserted; after the charging gun 10 is removed from the charging port 92, the automatic opening and closing structure of the dust cover can automatically return to the locked state, closing the charging port 92, without requiring manual operation throughout the process.

[0051] The charging socket 9 in this embodiment is a European standard socket with two charging ports 92, one above the other. The lower charging port 92 is a DC charging port 92, which has a greater need for sealing. Therefore, the automatic opening and closing structure of the dust cover in this embodiment is only used to seal the lower DC charging port 92.

[0052] See appendix Figure 1 Appendix Figure 2 and appendix Figure 3 The automatic opening and closing structure of the dust cover includes a mounting shell 1, a dust cover 2, and an opening component 3.

[0053] Mounting shell 1 is the mounting base for the entire automatic opening and closing structure of the dust cover. The mounting shell is mounted on the vehicle body via the mounting structure. Specifically, a mounting shell is provided at the location where the charging socket 9 is located. The mounting shell has a recessed cavity facing inwards. The panel of the charging socket 9 is fixedly connected to the mounting shell by fasteners, and the charging socket 9 is located on the side of the recess facing inwards. Mounting shell 1 is fixedly mounted on the lower side wall of the mounting shell by fasteners. The structure for mounting shell 1 to the mounting shell constitutes its mounting structure. Mounting shell 1 has a receiving cavity 11, and its upper opening communicates with the recessed cavity of the mounting shell. In other embodiments, the mounting shell can also be mounted at other locations on the vehicle body. Furthermore, mounting shell 1 can be integrally formed with the mounting shell to reduce the number of parts.

[0054] Both the dust cover 2 and the opening component 3 are hinged to the mounting housing 1, and their axes of rotation are parallel to each other. The dust cover 2 is closer to the charging socket 9 than the opening component 3. One end of the dust cover 2 in the longitudinal direction is hinged to the mounting housing 1, and this end is located in the receiving cavity 11 of the mounting housing 1. The other end of the dust cover 2 in the longitudinal direction is the cover body 21. The dust cover 2 has a fastened state and an open state. When in the fastened state, see the attached diagram. Figure 4 The cover 21 is fastened onto the charging port 92; when the cover is open, see the attached document. Figure 6 The cover 21 detaches from the charging port 92 and is located in the receiving cavity 11 on the mounting shell 1, so that the charging gun 10 can be inserted into the charging port 92. The dust cover 2 can be flipped down to change from the locked state to the unlocked state, and vice versa.

[0055] When the dust cover 2 is in the snap-fit ​​state, the hinge shaft 4 between the dust cover 2 and the mounting shell 1 is located diagonally below the cover body 21 and on the side of the cover body 21 far away from the cover 3, so that the hinge shaft 4 is farther away from the cover 3 than the cover body 21. The cover body 21 and the hinge shaft 4 are connected by an inclined connecting part 22. This makes the overall structure more compact and avoids the socket panel 91 being too far from the outer side of the vehicle. Two mating plates 23 protruding from the cover body 21 are provided on the back side of the cover body 21. The two mating plates 23 are parallel to each other, and each of the two mating plates 23 is provided with a long hole-shaped sliding groove 24. The sliding groove 24 is also inclined. When the dust cover 2 is in the snap-fit ​​state, the end of the sliding groove 24 near the rotation axis of the dust cover 2 is inclined towards the charging port 92.

[0056] The cover opening component 3 includes a load-bearing part 31 and a transmission part 32 arranged at a certain angle. The hinge shaft 4 between the cover opening component 3 and the mounting shell 1 is located at the junction of the load-bearing part 31 and the transmission part 32. Two pins 33 are provided at the end of the transmission part 32 away from the load-bearing part 31, and the two pins 33 are located on both sides of the transmission part 32.

[0057] Two pins 33 are located in two grooves 24 and can slide within them. During the rotation of the cover opening member 3, the cover opening member 3 can use the pins 33 to move the mating plate 23, thereby driving the dust cover 2 to rotate. Therefore, in this embodiment, the mating plate 23 constitutes a shift fork that cooperates with the pins 33. During the transmission process, the two pins 33 and the two shift forks can be driven on both sides of the transmission part 32, making the transmission more stable and reliable.

[0058] When the dust cover 2 is in the locked position, see Appendix Figure 4 The support portion 31 is in a vertically upward position and is located in front of the DC charging port 92, and also in the path of the charging gun 10 when it is inserted into the DC charging port 92. This ensures that the charging gun 10 encounters and pushes against the support portion 31 during insertion into the charging port 92. This position of the support portion 31 is taken as the initial blocking position of the cover opening member 3. The initial blocking position of the cover opening member 3 is a range; for example, in other embodiments, the support portion 31 can also be in an inclined state when the cover opening member 3 is in the initial blocking position, as long as it can be pushed and rotated by the charging gun 10.

[0059] After being pushed, the load-bearing part 31 will drive the entire cover 3 to rotate around its hinge axis 4. After the charging gun 10 is inserted into place, the entire cover 3 is pushed and flipped to the bottom of the charging gun 10, and the position of the cover 3 at this time is used as the flipping avoidance position. Both the dust cover 2 and the cover 3 are equipped with elastic elements. In this embodiment, the elastic elements are specifically torsion springs 5 ​​connected between the dust cover 2 and the mounting shell 1, and between the cover 3 and the mounting shell 1. The elastic element of the dust cover 2 is used to drive the dust cover 2 to rotate after the dust cover 2 is opened so that the cover 21 is fastened to the charging port 92 and kept in the fastened state. The elastic element on the cover 3 is used to drive the cover 3 to rotate back to the initial blocking position when the cover 3 is in the flipping avoidance position.

[0060] In other embodiments, only the dust cover 2 may be equipped with an elastic element, while the opening member 3 may not be equipped with an elastic element. In this way, when the dust cover 2 returns to the locked state, it can drive the opening member back to the initial blocking position. Alternatively, only the opening member 3 may be equipped with an elastic element, while the dust cover 2 may not be equipped with an elastic element. In this way, when the opening member 3 returns to the initial blocking position, it can drive the dust cover 2 back to the locked state.

[0061] In other embodiments, the elastic element can also be a tension spring, one end of which is connected to the panel of the charging socket 9 and the other end is connected to the dust cover 2. The tension spring can provide an upward pulling force on the dust cover 2, so that the dust cover 2 can automatically snap onto the charging port 92.

[0062] When the dust cover 2 is in the locked position, the transmission part 32 of the opening member 3 is tilted upward toward the dust cover 2. When the opening member 3 is pushed by the charging gun 10 and rotates as a whole, see Appendix Figure 5 The transmission unit 32 rotates downwards, which in turn drives the dust cover 2 to rotate downwards as well, causing the dust cover 2 to change from a locked state to an open state. During this process, the pin 33 first moves towards the rotation axis of the dust cover 2 in the slide groove 24. When the rotation axis of the dust cover 2, the pin 33, and the rotation axis of the opening component 3 are on the same plane, the pin 33 is located near one end of the slide groove 24 near the rotation axis of the dust cover 2. Then, it moves away from the rotation axis of the dust cover 2 in the slide groove 24. The bidirectional movement of the pin 33 in the slide groove 24 can improve the space utilization efficiency of the entire automatic opening and closing structure of the dust cover, making the overall structure more compact.

[0063] Since the insertion process of the charging gun 10 is synchronized with the rotation process of the cover opening component 3 and the dust cover 2, the dust cover 2 needs to be rotated to the bottom of the charging gun 10 before the charging gun 10 moves to the position of the dust cover 2, so as to avoid interference.

[0064] During the process of inserting the charging gun 10 into the charging port 92 and continuously charging the vehicle, see Appendix. Figure 6The charging gun 10 is positioned above the support part 31, preventing the support part 31 from rotating upwards, thus keeping the dust cover 2 in the open position at all times. After charging is complete and the charging gun 10 is removed, refer to the appendix. Figure 7 The dust cover 2 will flip upward under the drive of the torsion spring 5, thus returning to the locked state.

[0065] In order to achieve relative movement between the opening part 3 and the dust cover 2, when the dust cover 2 is in the latched state, the angle between the connection between the pin 33 and the rotation axis of the opening part 3 and the extension direction of the slide groove 24 on the lower side should be greater than or equal to 90 degrees.

[0066] The end of the slide groove 24 away from the hinge shaft 4 between the dust cover 2 and the mounting housing 1 has an opening for inserting the pin 33. During assembly, the dust cover 2 and the opening piece 3 can be installed independently onto the mounting housing 1. Then, the operator holds the load-bearing part 31 with one hand to adjust the angle of the opening piece 3, and holds the dust cover 2 with the other hand to adjust the angle of the dust cover 2. Finally, the pin 33 on the opening piece 3 is aligned with the opening on the slide groove 24 on the dust cover 2, and the pin 33 is slid into the slide groove 24.

[0067] To achieve the above objectives, when the dust cover 2 is in the locked state, the extension direction of the shift fork is tangent to the rotation path of the shift pin 33, so that the transmission part 32 can rotate in both the upward and downward directions. During assembly, the opening part 3 and the dust cover 2 can be installed onto the mounting shell 1 first, and then the shift pin 33 can be inserted from the end opening of the slide groove 24. After loosening the opening part 3 and the dust cover 2, the dust cover 2 can automatically reach the locked state.

[0068] Otherwise, before the dust cover 2 and the opening part 3 are installed on the mounting shell 1, the pin 33 must be inserted into the slide groove 24 first, and then the dust cover 2 and the opening part 3 must be installed on the mounting shell 1. During the installation of the dust cover 2 and the opening part 3, it is also necessary to maintain the relative matching relationship between the pin 33 and the slide groove 24. In addition, the installation operation is inconvenient due to the influence of the torsion spring 5.

[0069] However, to prevent the dust cover 2 from rotating excessively during the reset process, this embodiment requires that the reset force provided by the elastic element on the dust cover 2 be greater than the reset force provided by the elastic element on the opener 3. In other embodiments, for example, when the dust cover 2 is in the latched state, the angle between the connection direction of the pin 33 and the rotation axis of the opener 3 and the lower side of the extension direction of the slide groove 24 is greater than 90 degrees. This setting is not necessary because even if the reset force provided by the elastic element on the opener 3 is large, the opener 3 cannot drive the dust cover 2 to rotate excessively after the dust cover 2 has been latched onto the charging port 92.

[0070] In this embodiment, the automatic opening and closing structure of the dust cover is located on the lower side of the corresponding charging port 92. During the insertion process, the charging gun 10, due to its own weight, can press down on the load-bearing part 31 of the cover opening member 3, reducing the force required by the operator during charging. If it were located on other sides of the charging port 92, the operator would need to exert additional force in other directions during the insertion of the charging gun 10, making the charging operation inconvenient.

[0071] In other embodiments of this implementation, if there is enough space in the vehicle, the AC charging port 92 located on the upper side can also be equipped with an additional automatic dust cover opening and closing structure, with the two sets of automatic dust cover opening and closing structures arranged symmetrically on the upper and lower sides.

[0072] In other embodiments of this implementation, for the national standard charging socket 9, the DC charging port 92 and the AC charging port 92 are arranged horizontally at intervals. Then, both the DC charging port 92 and the AC charging port 92 can be equipped with an automatic dust cover opening and closing structure, and the automatic dust cover opening and closing structure is located below the corresponding charging port 92.

[0073] Specific embodiment 2 of the automatic opening and closing structure for the dust cover provided by the present invention: This embodiment is based on embodiment 1. The difference between this embodiment and embodiment 1 is that in this embodiment, the opening component 3 and the dust cover 2 adopt a different linkage structure.

[0074] See appendix Figure 8 The linkage structure includes a drive gear 7 coaxially arranged on the cover 3 and a driven gear 8 coaxially arranged on the dust cover 2. The drive gear 7 and the driven gear 8 directly mesh and transmit power, and the drive gear 7 is an incomplete gear.

[0075] The drive gear 7 and driven gear 8 are both arranged in pairs and distributed on both sides of the cover 3 and the dust cover 2. The distance between the two drive gears 7 and the two driven gears 8 is greater than the width of the charging gun 10, so as not to affect the charging gun 10 from being inserted into the charging port 92.

[0076] In other embodiments of this implementation, the drive gear 7 and the driven gear 8 can be driven by an intermediate gear, which reduces the size of the drive gear 7 and the driven gear 8.

[0077] Specific embodiment 3 of the automatic opening and closing structure of the dust cover provided by the present invention: This embodiment is based on embodiment 1. The difference between this embodiment and embodiment 1 is that the opening component 3 and the dust cover 2 adopt other linkage structures.

[0078] See appendix Figure 9In this embodiment, the pin 33 is disposed on the dust cover 2, while the fork is disposed on the opening member 3. Specifically, the pin 33 is disposed inside the mating plate 23 on the dust cover 2, and the transmission part 32 of the opening member 3 is provided with a sliding groove 24 so that the transmission part 32 constitutes the fork. When the opening member 3 rotates, the fork applies a force to the pin 33, causing the pin 33 to move, thereby causing the entire dust cover 2 to rotate.

[0079] Specific embodiment 4 of the automatic opening and closing structure for the dust cover provided by the present invention: This embodiment is based on Embodiment 1, but differs in that a different linkage structure is used between the cover opening component 3 and the dust cover 2. Specifically, see the appendix. Figure 10 The linkage structure is a connecting rod 6 that connects the end of the transmission part 32 of the cover opening part 3 and the mating plate 23 of the dust cover 2. The cover opening part 3, the dust cover 2 and the connecting rod 6 together form a double rocker mechanism.

[0080] Specific embodiment 5 of the automatic opening and closing structure for the dust cover provided by the present invention: This embodiment is based on Embodiment 1, but differs from Embodiment 1 in that the extension direction of the slide groove in this embodiment is parallel to the plane of the cover. Compared to Embodiment 1, in this embodiment, during the process of the dust cover changing from the fastened state to the open state, the pin moves unidirectionally in the slide groove, resulting in lower space utilization efficiency. Therefore, in this embodiment, the opening component and the dust cover as a whole occupy a larger space.

[0081] Specific embodiment 6 of the automatic opening and closing structure for the dust cover provided by the present invention: This embodiment is based on Embodiment 1, but differs in that, in this embodiment, when the dust cover is in the snap-fit ​​state, the hinge axis between the dust cover and the mounting shell is located directly below the cover. Since the rotation of the dust cover requires a certain amount of space, the position of the hinge axis cannot be moved based on Embodiment 1; instead, the position of the cover needs to be changed. This results in the dust cover occupying the space of the original charging socket, leading to poor structural compactness.

[0082] Specific embodiment 7 of the automatic opening and closing structure for the dust cover provided by the present invention: This embodiment is based on embodiment 1. The difference between this embodiment and embodiment 1 is that the hinge axis of the cover opening component extends forward and backward, so that the rotation axis of the dust cover and the cover opening component are perpendicular to each other. The cover opening component and the dust cover are linked by a bevel gear. The load-bearing part of the cover opening component is provided with a wedge surface for cooperating with the charging gun. During the insertion process, the charging gun will press against the wedge surface, causing the cover opening component to rotate as a whole.

[0083] Specific embodiment 8 of the automatic opening and closing structure for the dust cover provided by the present invention: This embodiment is based on Embodiment 1, but differs in that the automatic opening and closing structure of the dust cover is integrated into the charging socket. Specifically, the socket panel of the charging socket has a mounting base integrally formed, and the dust cover and the opening mechanism are hinged to the mounting base.

[0084] In this embodiment, the mounting base can be two mounting substrates, which are respectively connected to the left and right sides of the socket panel; the mounting base can also be the mounting shell in embodiment 1.

[0085] In other embodiments of this implementation, the mounting base can also be fixedly mounted on the socket panel by fasteners such as bolts.

[0086] Specific embodiments of the charging socket provided by the present invention: The charging socket integrates an automatic dust cover opening and closing structure. The socket panel of the charging socket is integrally machined or fixedly connected to the mounting base by fasteners. The dust cover and the opening component are both hinged to the mounting base. The specific structure of the dust cover and the opening component and the cooperation relationship between them are the same as those in the above-mentioned automatic dust cover opening and closing structure, and will not be described again.

[0087] In this embodiment, the automatic dust cover opening and closing structure can be assembled onto the vehicle body along with the charging socket during assembly.

[0088] Specific embodiment 1 of the vehicle provided by the present invention: The vehicle includes a body, on which a mounting shell and a charging socket connected to the mounting shell are provided. The charging socket integrates an automatic dust cover opening and closing mechanism. This charging socket has the same structure as the charging socket in the specific embodiment described above, and will not be described again. In this embodiment, the mounting shell has space provided to avoid the automatic dust cover opening and closing mechanism.

[0089] Specific embodiment 2 of the vehicle provided by the present invention: The vehicle body includes an assembly shell for mounting a charging socket. An integrally formed mounting base or a mounting body fixedly connected to the assembly shell by fasteners is provided. The dust cover and the opening mechanism are hinged to the mounting base. The specific structure of the dust cover and the opening mechanism, as well as the cooperation between them, are the same as those in the above-mentioned automatic dust cover opening and closing structure, and will not be described again.

[0090] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
