[0028] Example

[0029] like Figures 1 to 3As shown, the protective cover for a battery swapping connector proposed in this utility model includes: a first protective cover 1 and a second protective cover 2. A locking block 3 and a locking seat 4 are respectively fixedly disposed at the same end of the first protective cover 1 and the second protective cover 2. This design allows the locking block 3 and the locking seat 4 to be interlocked. A connecting bolt 7 for fixing the first protective cover 1 and the second protective cover 2 is provided between the locking block 3 and the locking seat 4. By passing the connecting bolt 7 through the corresponding holes on the locking block 3 and the locking seat 4 and tightening it, a stable connection between the two protective covers can be achieved, thus forming a complete protective cover structure.

[0030] In this embodiment, a sealing ring 5 is also included, which is sleeved on the outer wall of the card block 3 and can seal the gap between the first protective cover 1 and the second protective cover 2. The outer wall of the card block 3 is provided with a card groove 8, and the card groove 8 is sleeved with the sealing ring 5. During installation, the sealing ring 5 needs to be tightly sleeved in the card groove 8 on the outer wall of the card block 3 to ensure that the sealing ring 5 fits tightly in the card groove 8. At the same time, the card block 3 is provided with a limiting component 6 for providing pressure to the sealing ring 5 to further enhance the sealing effect.

[0031] like Figures 3 to 5 As shown, the limiting component 6 includes multiple mounting slots 61 formed on the locking block 3, and the mounting slots 61 are L-shaped to facilitate the installation of other components in the limiting component 6. A fixing plate 62 is fixedly installed inside each mounting slot 61, providing stable support for the installation and movement of other components. A connecting rod 63 is movably threaded through the fixing plate 62, allowing it to slide flexibly on the fixing plate 62. A pressure strip 64 is fixedly connected to one end of the connecting rod 63, and a connecting strip 65 is fixedly connected to the other end. A spring 66 is sleeved on the outer wall of the connecting rod 63, with one end of the spring 66 fixedly connected to the fixing plate 62 and the other end fixedly connected to the connecting strip 65. When the card block 3 is inserted into the card holder 4, the inner wall of the card holder 4 presses against the pressure block 67. Since the mounting groove 61 is an "L"-shaped structure, the pressure block 67 slides within the mounting groove 61 along the direction of the guide groove 9. The inner wall of the mounting groove 61 has a guide groove 9, and a guide block 10 is slidably disposed inside the guide groove 9. The guide block 10 is fixedly connected to the pressure block 67, and the cooperation between the guide block 10 and the guide groove 9 ensures the stability of the sliding of the pressure block 67. During the sliding process, because the surface of the pressure block 67 that is in contact with the connecting strip 65 is inclined, it pushes the connecting strip 65 to move away from the pressure block 67. The connecting strip 65 then drives the connecting rod 63 to slide on the fixed plate 62. The pressure strip 64 at one end of the connecting rod 63 exerts pressure on the sealing ring 5 as the connecting rod 63 moves. At the same time, the spring 66 sleeved on the outer wall of the connecting rod 63 is compressed. The reaction force generated by the spring 66 continuously provides pressure on the sealing ring 5 to the pressure strip 64, ensuring that the sealing ring 5 fits tightly against the connection gap between the card block 3 and the card seat 4, achieving a good sealing effect, effectively preventing dust, moisture and other impurities from entering, and protecting the internal structure of the battery swapping connector.

[0032] In this embodiment, the sealing ring 5 is fitted into the groove 8 on the outer wall of the locking block 3, ensuring that the sealing ring 5 fits tightly into the groove 8. The end of the first protective cover 1 with the locking block 3 and the end of the second protective cover 2 with the locking seat 4 are aligned, so that the locking block 3 is inserted into the locking seat 4 and fitted together, connecting the two protective covers. Subsequently, the connecting bolt 7 is passed through the corresponding holes on the locking block 3 and the locking seat 4, and the connecting bolt is tightened to complete the fixed connection of the first protective cover 1 and the second protective cover 2, forming a complete protective cover structure.

[0033] When the locking block 3 is inserted into the locking seat 4, the inner wall of the locking seat 4 presses against the pressure block 67. Because the mounting groove 61 is an "L"-shaped structure, the pressure block 67 slides within the mounting groove 61 along the direction of the guide groove 9. The guide block 10 within the guide groove 9 is fixedly connected to the pressure block 67, ensuring the stability of the pressure block 67's sliding motion. During the sliding process, the pressure block 67 pushes the connecting strip 65 to move away from the pressure block 67. The connecting strip 65 drives the connecting rod 63 to slide on the fixing plate 62, which is fixed within the mounting groove 61.

[0034] As the connecting rod 63 moves, the pressure strip 64 at one end of the connecting rod 63 exerts pressure on the sealing ring 5. At the same time, the spring 66 sleeved on the outer wall of the connecting rod 63 is compressed. One end of the spring 66 is fixed to the fixing plate 62, and the other end is fixed to the connecting strip 65. The reaction force generated by the spring 66 continuously provides pressure on the sealing ring 5 through the pressure strip 64, ensuring that the sealing ring 5 fits tightly against the connection gap between the card block 3 and the card seat 4, achieving a good sealing effect.

[0035] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
