[0029] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0030] This embodiment provides a dustproof device for a charging stand, such as Figures 1 to 9 As shown, a charging interface 101 is provided on the end surface of the charging seat 1 and is used to dock with the charging gun 7, and includes a cover body 2 for buckling the charging interface 101, a cover body mounting bracket 3 installed on the end surface of the charging seat 1, a fixing mechanism 4, a locking mechanism 5 and an unlocking mechanism 6 provided on the cover body mounting bracket 3. The cover body 2 is connected to the fixing mechanism 4, the fixing mechanism 4 is configured to keep the cover body 2 in the buckled position, and the locking mechanism 5 is configured to engage with the cover body 2 to keep the cover body 2 in the open position when the cover body 2 is in the open position; the unlocking mechanism 6 is configured to drive the locking mechanism 5 to disengage from the buckled connection with the cover body 2 and put the cover body 2 in the expanded position when the cover body 2 is in the open position and the charging gun 7 is inserted into the charging interface 101, and when the charging gun 7 is pulled out of the charging interface 101, the cover body 2 is restored to the buckled position by the fixing mechanism 4 and is kept in the buckled position.

[0031] In this embodiment, a mounting opening is provided near the charging port 101, and the mounting opening is used to assemble the cover mounting bracket 3. The cover 2 is hingedly connected to the cover mounting bracket 3 through a fixing mechanism 4, so that the cover 2 can move relative to the cover mounting bracket 3 to open or close, and ensure that each time the cover 2 is fastened, it will stably cover the charging port 101, ensuring the purpose of waterproofing and dustproofing the charging stand 1. The locking mechanism 5 can move relative to the cover mounting bracket 3. When the cover 2 is opened, the locking mechanism 5 engages with the cover 2 and locks the cover 2 in a position such as Figure 6 The open position shown in the figure facilitates the insertion of the charging gun 7 into the charging interface 101. The operation is simple and easy to operate, and there will be no plugging errors, which improves work efficiency. The unlocking mechanism 6 can move relative to the cover mounting bracket 3. When the charging gun 7 is inserted into the charging interface 101, the unlocking mechanism 6 moves the cover 2 toward Figure 7 The cover 2 is flipped from the expanded position shown, that is, the cover 2 is further opened, and the locking mechanism 6 is disengaged from the cover 2, so that the cover 2 can rotate relative to the cover mounting bracket 3. When the charging gun 7 is pulled out of the charging interface 101, the cover 2 is automatically flipped toward the buckled position by the fixing mechanism 4 without the obstruction of the charging gun 7 and the locking mechanism 5, and the cover 2 is kept in the buckled position.

[0032] Through the above technical solution, when the cover body 2 is in the open position, the locking mechanism 5 is engaged with the cover body 2 to keep the cover body 2 in the open position; when the charging gun 7 is inserted into the charging interface 101, the unlocking mechanism 6 drives the locking mechanism 5 to disengage from the engagement with the cover body 2 and puts the cover body 2 in the expanded position; after the charging gun 7 is pulled out of the charging interface 101, the cover body 2 is restored and kept in the buckled position through the fixing mechanism 4. The locking mechanism 5 is automatically disengaged from the cover body 2 through the unlocking mechanism 6, so that the cover body 2 automatically rebounds and buckles, thereby solving the problem that the dust cover is difficult to operate and time-consuming and labor-intensive during the buckling process.

[0033] In some embodiments, reference Figure 2 and Figure 3 The cover body 2 is provided with a rotating part 201, and the rotating part 201 is provided with a first axial hole along the axial direction of rotation of the cover body 2. The fixing mechanism 4 includes a first rotating shaft 401. A pin shaft or a pin sleeve is provided on the cover body mounting bracket 3. The first rotating shaft 401 passes through the first axial hole and is installed in the pin shaft or the pin sleeve, so that the cover body 2 can rotate around the first rotating shaft 401. Most of the area of ​​the cover body 2 is used to cover the charging interface 101. In order to enable the cover body 2 to rotate to the open position or the buckled position, it is necessary to set the rotating part 201 on one side of the cover body 2. The first rotating shaft 401 penetrates into the rotating part 201 along the axial direction of rotation of the cover body 2 and is integrally formed with the cover body 2. The rotating part 201 is hinged with the cover body mounting bracket 3 through the first rotating shaft 401, so that the cover body 2 can rotate relative to the cover body mounting bracket 3.

[0034] In order to allow the cover 2 to automatically rotate relative to the cover mounting bracket 3, in some embodiments, reference Figure 2 and Figure 3 The fixing mechanism 4 may include a first torsion spring 402, which is sleeved on the first rotating shaft 401, one end of the torsion arm of the first torsion spring 402 is fixed on the cover 2, and the other end of the torsion arm is fixed on the cover mounting bracket 3. The fixing mechanism 4 is configured to drive the cover 2 to rotate and finally maintain the buckled position under the restoring characteristics of the first torsion spring 402. In this way, the cover 2 relies on the elasticity of the first torsion spring 402 itself to rotate the cover 2 relative to the cover mounting bracket 3 through the first rotating shaft 401, thereby realizing the automatic closing of the cover 2.

[0035] In order to fix the cover 2 in the open position so as to facilitate the insertion of the charging gun 7 into the charging interface 101, in some embodiments, reference Figure 2 and Figure 3 , a locking groove 202 is provided on the rotating part 201, and the locking mechanism 5 may include a second rotating shaft 501, a locking plate 502 sleeved on the second rotating shaft 501, and a second torsion spring 503, the second rotating shaft 501 is mounted on the cover mounting bracket 3, one end of the torsion arm of the second torsion spring 503 is fixed on the locking plate 502, and the other end of the torsion arm is fixed on the cover mounting bracket 3, and the locking mechanism 5 is configured to drive the locking plate 502 to engage with the locking groove 202 under the restoring characteristics of the second torsion spring 503 to keep the cover 2 in the open position. In this embodiment, the locking plate 502 can move relative to the cover mounting bracket 3 around the second rotating shaft 501. The second torsion spring 503 makes the locking plate 502 have a tendency to rotate toward the locking groove 202, so that the locking plate 502 can engage with the locking groove 202 at any time; the locking plate 502 is inserted into the locking groove 202 to prevent the cover 2 from rotating to the buckled position. It should be noted that the locking plate 502 can be in the shape of a flat plate. The flat plate surface increases the contact area between the locking plate 502 and the locking groove 202, making the locking effect more stable.

[0036] In some embodiments, the torque of the first torsion spring 402 on the cover 2 is greater than the torque of the second torsion spring 503 on the locking plate 502. This arrangement can ensure that the cover 2 will not interfere with or lose its position when returning to the buckled position, thereby improving the reliability of the device.

[0037] In some embodiments, reference Figure 1 , Figures 3 to 5 and Fig. 9, a through hole 102 penetrating to the charging interface 101 is provided on the end surface of the charging seat 1, a lifting groove 203 is provided on the side of the rotating part 201 opposite to the locking groove 202, and the unlocking mechanism 6 may include a lever 601 sleeved on the second rotating shaft 501, and the lever 601 is rotatable relative to the second rotating shaft 501. In order to unlock the locking mechanism 5 after the charging gun 7 is inserted into the charging interface 101, the first free end 602 needs to be extended into the through hole 102 and exposed in the charging interface 101. The second free end 603 of the lever 601 opposite to the first free end 602 is used to match the lifting groove 203, so that the lever 601 drives the rotation of the cover body 2 through the lifting groove 203.

[0038] In this embodiment, refer to Figure 4 , Figure 5 and Figure 7 , a lifting block 605 located below the locking plate 502 is provided on the side surface of the second free end 603. The lifting block 605 may be in the shape of a rectangular block, and the side of the lifting block 605 facing the locking plate 502 abuts against the locking plate 502. When the cover 2 is in the open position and the charging gun 7 is inserted into the charging port 101, the charging gun 7 presses down the first free end 602 to rotate the lever 601, driving the second free end 603 to rise and push the lifting groove 203 to separate from the lifting groove 203, and at the same time driving the lifting block 605 to lift the locking plate 502 out of the locking groove 202, so that the cover 2 is released. Figure 6 The open position shown switches to Figure 7 Expanded position shown.

[0039] It should be noted that there is only a small interference between the second free end 603 and the lifting groove 203. Figure 7 When the cover 2 is in the expanded position shown, the second free end 603 is disengaged from the lifting groove 203, and at the same time, the locking mechanism 5 is disengaged from the rotating part 201, and the cover 2 can be flipped from the expanded position to the engaged position under the drive of the first torsion spring 402. In this way, the locking mechanism 5 is automatically disengaged from the cover 2 by the unlocking mechanism 6, without manual intervention, and the operation is simple, which further improves the work efficiency.

[0040] It should be understood that the lifting block 605 is arranged in a rectangular block shape, which increases the contact area between the unlocking mechanism 6 and the locking mechanism 5, and ensures the stability and reliability of the unlocking mechanism 6 in the process of lifting the locking mechanism 5. Furthermore, the lifting block 605 and the lever 601 are integrally formed, which enhances the overall strength of the components and further improves the reliability of the device.

[0041] In some embodiments, reference Figure 7 and Figure 8The first free end 602 of the lever 601 can swing a set angle in the through hole 102. The swing radius of the first free end 602 can at least be in the same horizontal plane as the side wall of the charging interface 101, so as not to interfere with the insertion of the charging gun 7 into the charging interface 101, thereby improving the reliability of the device.

[0042] Further, refer to Figure 5 , Figure 7 and Figure 8 A smooth transition section 604 is provided on the first free end 602 of the lever 601 facing the opening of the charging interface 101. When the charging gun 7 contacts the first free end 602, the side wall of the charging gun 7 abuts against the smooth transition section 604, avoiding stress concentration and improving the strength of the lever 601; at the same time, it also plays a certain guiding role, making the side wall of the charging gun 7 smoother in the process of pressing down the first free end 602, thereby improving the reliability and service life of the device.

[0043] In some embodiments, reference Figure 2 , Figure 7 and Figure 8 The cover body 2 is driven by the restoring characteristics of the first torsion spring 402 from Figure 7 The expanded position shown switches to Fig. 9 During the process of the snap-fitting position shown, the charging gun 7 abuts against at least part of the cover body 2, preventing the cover body 2 from returning to the snap-fitting position. Without the locking mechanism 5 and the unlocking mechanism 6 to limit the cover body 2, the cover body 2 can be flipped from the expanded position toward the snap-fitting position under the drive of the first torsion spring 402. Since the charging gun 7 is inserted into the charging interface 101, the cover body 2 will abut against the outer wall of the charging gun 7, and this arrangement will not affect the normal charging operation. Moreover, when charging is completed, the charging gun 7 is pulled out. At this time, the cover body 2 is abutted against the charging gun 7 by the drive of the first torsion spring 402, which does not affect the pulling out operation of the charging gun 7.

[0044] In some embodiments, reference Figure 2 , Figure 8 and Fig. 9In the process of pulling out the charging gun 7 from the charging interface 101, the cover body 2 continues to return to the snap-fit ​​position from the position where the cover body 2 and the charging gun 7 abut against each other due to the recovery characteristics of the first torsion spring 402. When the charging gun 7 is completely pulled out, the cover body 2 is not blocked, so the cover body 2 automatically rebounds to the snap-fit ​​position and remains in the snap-fit ​​position under the drive of the first torsion spring 402, which is simple to operate and further improves work efficiency. Moreover, after the charging gun 7 is completely pulled out, the first free end 602 of the lever 601 is no longer subjected to force, and the lifting effect of the lever 601 on the locking plate 502 is invalid. The locking plate 502 is driven to move toward the rotating part 201 under the recovery characteristics of the second torsion spring 503, and the end of the locking plate 502 facing the cover body 2 is overlapped on the rotating part 201. At the same time, the locking plate 502 presses down the lifting block 605, and the lever 601 rotates synchronously with the locking plate 502 through the lifting block 605 under the drive of the second torsion spring 503. According to the lever principle, while the second free end 603 of the lever 601 moves downward, the first free end 602 of the lever 601 is lifted up and extends into the charging interface 101, so as to contact the charging gun 7 during the next charging. In this way, when the charging gun 7 is pulled out, the cover 2 is automatically closed, which is simple to operate, saves time and effort, and improves the comfort of the user.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present disclosure.
