However, they have the following technical defects: traditional dust covers lack an effective locking mechanism after opening, and are prone to accidental closure due to external impact or vibration, affecting charging operation. They also require manual maintenance of the open state or rely on complex mechanical structures for positioning, resulting in inconvenient operation and easy wear of components. Utility Model Content

[0003] One objective of this invention is to provide a new technical solution for a dust cover structure and a charging base.

[0004] According to a first aspect of this utility model, a dust cover structure is provided, including a hinge base and a dust cover hinged to the hinge base. An elastic reset structure for keeping the dust cover in an open state is provided between the hinge base and the dust cover. An axially oriented mounting cavity is provided in the hinge base, and an auxiliary positioning mechanism is slidably disposed in the mounting cavity. The auxiliary positioning mechanism includes a limiting component for positioning the dust cover and a driving component for converting the flipping motion of the dust cover into the axial motion of the limiting component. An elastic component for supporting the auxiliary positioning mechanism is provided between the limiting component and the bottom wall of the mounting cavity. Correspondingly cooperating snap-fit ​​structures are provided on the outer walls of the limiting component and the dust cover. When the dust cover is in an open state, the limiting component and the dust cover are engaged through the snap-fit ​​structures to position the dust cover in the open state.

[0005] Optionally, the snap-fit ​​structure includes a protruding rib on the outer wall of the limiting component facing the dust cover, and a slot on the dust cover corresponding to the protruding rib. When the dust cover is in the open state, the limiting component and the dust cover are snap-fitted together through the protruding rib and the slot.

[0006] Optionally, at least one limiting portion is provided protruding on the outer side wall of the drive assembly, and the top of the hinge seat collapses inward to form a receiving groove for accommodating the limiting portion. When the dust cover is in the closed state, the limiting portion is at least partially embedded in the receiving groove.

[0007] Optionally, mounting plates are symmetrically arranged on both sides of the top of the hinge seat, and one end of the dust cover is hinged to the mounting plate by a pin.

[0008] Optionally, the elastic reset structure is a torsion spring partially surrounding the outside of the pin.

[0009] Optionally, the driving assembly includes a driving block and a core rod integrally formed with the driving block, the elastic component is a return spring, and the end of the core rod away from the driving block passes through the mounting hole of the limiting component and the return spring in sequence, and is inserted into the guide hole in the bottom wall of the mounting cavity.

[0010] Optionally, the limiting component has a through groove at one end facing the drive block, the through hole is provided on the bottom wall of the through groove, and the end of the drive block connected to the core rod is received in the through groove.

[0011] Optionally, the end of the drive block away from the core rod is formed with a clamping claw that is arranged opposite to it, and the pin is engaged with the inside of the clamping claw.

[0012] Optionally, a pressure seat is provided on the inner side of the dust cover, and a pressure groove matching the shape of the drive block is opened in the pressure seat. During the process of the dust cover flipping from the open state to the closed state, the dust cover provides an axial force to the auxiliary positioning mechanism through the pressure groove to drive the drive assembly to move axially.

[0013] Optionally, the pressure seat is located on the insertion path of the pin, and both ends of the pin pass through the pressure seat and are hinged to the corresponding mounting plate.

[0014] Optionally, the present invention also provides a charging stand, including a body and any of the dust cover structures described above. The end of the body is further provided with a fixing seat for locking the dust cover. When the dust cover is flipped to the closed state, the dust cover is locked by the fixing seat.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By cooperating with the locking structure on the dust cover, the limit component automatically locks when the dust cover is fully open, avoiding accidental closure caused by external interference. At the same time, the drive component converts the flipping motion of the dust cover into the axial motion of the limit component, ensuring the synchronicity and reliability of the locking action.

[0017] 2. The drive assembly and limit assembly are integrated into the mounting cavity of the hinge seat. The axial sliding design of the core rod, return spring and guide hole reduces the number of independent parts and reduces assembly complexity.

[0018] 3. The drive block and the gripper structure directly engage the pin shaft, simplifying the transmission path and avoiding the wear risk of traditional multi-link structures.

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0031] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0033] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] According to the first aspect of this utility model, as Figures 1-6 As shown, a dust cover 10 structure is provided, including a hinge base 20 and a dust cover 10 hinged to the hinge base 20. An elastic reset structure is provided between the hinge base 20 and the dust cover 10 to keep the dust cover 10 in an open state. An axially oriented mounting cavity 22 is provided in the hinge base 20, and an auxiliary positioning mechanism is slidably disposed in the mounting cavity 22. The auxiliary positioning mechanism includes a limiting component 60 for positioning the position of the dust cover 10 and a driving component 50 for converting the flipping motion of the dust cover 10 into the axial motion of the limiting component 60. An elastic component for supporting the auxiliary positioning mechanism is provided between the limiting component 60 and the bottom wall of the mounting cavity 22. Correspondingly matched snap-fit ​​structures are provided on the outer walls of the limiting component 60 and the dust cover 10. When the dust cover 10 is in an open state, the limiting component 60 and the dust cover 10 are engaged through the snap-fit ​​structures to position the dust cover 10 in the open state.

[0035] With the popularization of new energy vehicles, the design of the dust cover 10 on the charging dock of new energy vehicles has become a key component to ensure interface cleanliness and extend service life. Currently, most dust covers 10 on the market adopt a simple hinge structure, relying on manual opening and closing or a single spring reset. However, this has the following technical defects: traditional dust covers 10 lack an effective locking mechanism after opening, making them prone to accidental closure due to external impacts or vibrations, affecting charging operations. Furthermore, they require manual maintenance to keep open or rely on complex mechanical structures for positioning, leading to inconvenient operation and easy wear of components.

[0036] This utility model achieves automatic locking when the dust cover 10 is fully opened by cooperating with the limiting component 60 and the snap-fit ​​structure on the dust cover 10, thus avoiding accidental closure caused by external interference. At the same time, the drive component 50 converts the flipping motion of the dust cover 10 into the axial motion of the limiting component 60, ensuring the synchronicity and reliability of the snap-fit ​​action.

[0037] In some embodiments, such as Figures 1-2As shown, the snap-fit ​​structure includes a protruding rib 61 on the outer wall of the limiting component 60 facing the dust cover 10, and a slot 111 on the dust cover 10 corresponding to the protruding rib 61. When the dust cover 10 is in the open state, the limiting component 60 and the dust cover 10 are snap-fitted together by the protruding rib 61 and the slot 111.

[0038] The shape of the slot 111 matches the rib 61. When the dust cover 10 is flipped to the maximum opening angle, the rib 61 slides into the slot 111 and locks its position through friction or mechanical interference. The physical engagement between the rib 61 and the slot 111 ensures the stability of the dust cover 10 when it is fully open, and avoids accidental closure due to vibration or external force. The structure is simple, no additional locking parts are required, and the manufacturing cost is reduced.

[0039] In some embodiments, such as Figures 1-2 As shown, at least one limiting part 54 protrudes from the outer side wall of the drive assembly 50, and the top of the hinge seat 20 collapses inward to form a receiving groove 23 for accommodating the limiting part 54. When the dust cover 10 is in the closed state, the limiting part 54 is at least partially embedded in the receiving groove 23.

[0040] The limiting part 54 can be a protrusion or a boss, and the receiving groove 23 is a recessed guide groove. In the closed state, the cooperation between the limiting part 54 and the receiving groove 23 constrains the axial displacement range of the drive assembly 50. It can also prevent the drive assembly 50 from shifting during axial movement, improving the reliability of operation. Furthermore, the embedding of the limiting part 54 and the receiving groove 23 further fixes the closed position of the dust cover 10, enhancing the sealing performance.

[0041] In some embodiments, such as Figures 1-2 As shown, mounting plates 21 are symmetrically arranged on both sides of the top of the hinge seat 20, and one end of the dust cover 10 is hinged to the mounting plate 21 by a pin 30.

[0042] Mounting plate 21 and hinge seat 20 are integrally formed. Pin 30 passes through the end of dust cover 10 and the shaft hole on mounting plate 21 to realize the rotational freedom of dust cover 10. The double mounting plate 21 design disperses the hinge torque and reduces unilateral wear. The pin 30 has a clear insertion path and is easy to assemble.

[0043] In some embodiments, such as Figure 1 As shown, the elastic reset structure is a torsion spring 40 that partially surrounds the outside of the pin 30.

[0044] The two ends of the torsion spring 40 abut against the dust cover 10 and the hinge seat 20 respectively. The elastic potential energy of the torsion spring 40 drives the dust cover 10 to rotate in the opening direction. The user can trigger the dust cover 10 to pop open with a light touch, which is convenient to operate.

[0045] In some embodiments, such asFigures 3-5 As shown, the drive assembly 50 includes a drive block 51 and a core rod 52 integrally formed with the drive block 51. The elastic component is a reset spring 70. The end of the core rod 52 away from the drive block 51 passes through the mounting hole 621 of the limiting assembly 60 and the reset spring 70 in sequence, and is inserted into the guide hole 221 on the bottom wall of the mounting cavity 22.

[0046] The return spring 70 is sleeved on the outside of the core rod 52, with one end abutting against the limiting component 60 and the other end abutting against the guide hole in the bottom wall of the mounting cavity 22. Axial reset is achieved by compressing / releasing the return spring 70. This design converts the flipping motion of the dust cover 10 into the linear motion of the drive component 50, simplifying the transmission path. Moreover, the return spring 70 can absorb the impact force during closing, extending the service life of the component.

[0047] In some embodiments, such as Figures 3-5 As shown, the limiting component 60 has a through groove 62 at one end facing the driving block 51, and the through hole 621 is provided on the bottom wall of the through groove 62. The end of the driving block 51 connected to the core rod 52 is received in the through groove 62.

[0048] Firstly, the through slot 62 is used to accommodate the drive block 51, reducing the overall structural volume. Secondly, the inner wall of the through slot 62 is used to radially limit the drive block 51 and prevent it from swaying.

[0049] In some embodiments, such as Figures 1-3 As shown, the drive block 51 has a gripper 53 formed at one end away from the core rod 52, and the pin 30 is engaged with the inner side of the gripper 53.

[0050] The inner side of the gripper 53 is provided with an arc-shaped groove that matches the outer diameter of the pin 30, which facilitates the drive block 51 to drive the pin 30 through the gripper 53 and also facilitates assembly.

[0051] In some embodiments, such as Figures 1-2 As shown, a pressure seat 11 is provided on the inner side of the dust cover 10. The pressure seat 11 has a pressure groove 112 that matches the shape of the drive block 51. During the process of the dust cover 10 flipping from the open state to the closed state, the dust cover 10 provides an axial force to the auxiliary positioning mechanism through the pressure groove 112 to drive the drive assembly 50 to move axially.

[0052] The groove 112 is set to match the shape of the drive block 51. During the closing process of the dust cover 10, the groove 112 squeezes the drive block 51, driving it to move axially, converting the flipping force into axial driving force, reducing the load on the hinge part, and the matching of the shape of the groove 112 with the drive block 51 ensures accurate motion trajectory.

[0053] In some embodiments, such as Figure 2As shown, the pressure seat 11 is located on the insertion path of the pin 30, and the two ends of the pin 30 pass through the pressure seat 11 and are hinged to the corresponding mounting plate 21.

[0054] The pressure seat 11 has a through hole in the center for the pin 30 to pass through. The pressure seat 11 is fixedly connected to the dust cover 10. The pin 30 also serves as the rotation fulcrum of the pressure seat 11. The pin 30 serves as both the rotation shaft and the force transmission medium, thus improving efficiency through dual functions.

[0055] In some embodiments, such as Figure 6 As shown, this utility model also provides a charging stand, including a body 80 and any of the dust cover 10 structures described above. The end of the body 80 is also provided with a fixing seat 90 for locking the dust cover 10. When the dust cover 10 is flipped to the closed state, the dust cover 10 is locked by the fixing seat 90.

[0056] The fixing base 90 is equipped with a fastening structure, a snap-on structure, or a magnetic structure. The edge of the dust cover 10 is provided with a corresponding conformal shape of the fastening structure, a locking tongue, or a magnetic component. When closed, the two cooperate to fix it. The fixing base 90 ensures that the dust cover 10 fits tightly after closing to prevent dust from entering.

[0057] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
