Detailed Implementation

[0027] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0028] refer to Figure 1-3A battery pack interface plug includes a cover plate 11, an outer shell 21, and a snap-fit ​​structure. The outer shell 21 is fixedly connected to the cover plate 11, and the snap-fit ​​structure is installed on the cover plate 11. An inner shell 24 is fixedly connected to the cover plate 11. The inner shell 24 is located inside the outer shell 21, and a sealing sleeve 31 is installed on the inner shell 24. The sealing sleeve 31 is located between the inner shell 24 and the outer shell 21, and the snap-fit ​​structure is located between the sealing sleeve 31 and the outer shell 21.

[0029] The inner shell 24 has a slot 25, and a locking block 32 that engages with the sealing sleeve 31 is fixedly connected to the slot 25. The locking block 32 engages with the inner shell 24 by engaging with the slot 25, preventing the sealing sleeve 31 from slipping off the inner shell 24. The sealing sleeve 31 has a limiting step 34, which engages with the end of the inner shell 24 away from the cover plate 11. The limiting step 34 engages with the inner shell 24, limiting the sealing sleeve 31 and preventing it from sliding on the inner shell 24. The end of the locking block 32 near the cover plate 11 has a chamfer 33, which abuts against the inner shell 24.

[0030] The snap-fit ​​structure includes a support block 41, a support rod 42, and a latch 43. The support block 41 is fixedly connected to the cover plate 11, and the support rod 42 is fixedly connected to the middle of the support block 41. The latch 43 is fixedly connected to the support rod 42 and is located between the sealing sleeve 31 and the outer shell 21. The latch 43 has an engaging surface on the side near the support block 41. The support block 41 is made of plastic and can undergo elastic deformation under force. There are two support rods 42, and the latch 43 is fixedly connected to both ends of the two support rods 42 respectively. There are also two support blocks 41, each corresponding to one of the two support rods 42. The snap-fit ​​structure also includes a pressure plate 44, which is fixedly connected to the support rod 42. The pressure plate 44 and the latch 43 are located at both ends of the support rod 42 respectively. The pressure plate 44 is fixedly connected to an anti-slip boss 45.

[0031] The outer casing 21 has a movable groove 22, and the latch 43 is located within the movable groove 22. The movable groove 22 prevents the latch 43 from being jammed by the outer casing 21. The outer casing 21 also has a guide groove 23, which is located on both sides of the outer casing 21, along with the movable groove 22.

[0032] A pull plate 12 is fixedly connected to the cover plate 11. A rib 13 is provided on the side of the pull plate 12 near the support rod 42. The rib 13 is fixedly connected to both the pull plate 12 and the cover plate 11. A limiting plate 14 is fixedly connected to the cover plate 11. The limiting plate 14 is located between the support rod 42 and the pull plate 12, and it engages with the support rod 42. After the support rod 42 is pushed to rotate on the support block 41, releasing the engagement between the latch 43 and the battery pack interface 51, the limiting plate 14 can engage with the support rod 42, preventing excessive rotation of the support rod 42 and damage to the support block 41, thus limiting the position of the support rod 42. Surrounding plates 15 are fixedly connected to both ends of the limiting plate 14, and are fixedly connected to both the limiting plate 14 and the cover plate 11. The surrounding plates 15 provide support to the limiting plate 14, improving its structural stability. The support rod 42 is located between the two enclosures 15 and can protect the buckle structure through the two enclosures 15 to prevent damage caused by collision between external objects and the buckle structure.

[0033] This embodiment has the following advantages:

[0034] Insert the battery pack interface 51 between the outer casing 21 and the sealing sleeve 31, ensuring the sealing sleeve 31 is tightly fitted to the battery pack interface 51. Push the cover plate 11 towards the battery pack interface 51, causing the snap-fit ​​structure to lock the battery pack interface 51 in place, thus installing the cover onto the battery pack interface 51. The installation process is simple and convenient, achieving the advantage of ease of use.

[0035] The cover plate 11 and the outer shell 21 surround and wrap around the battery pack interface 51, blocking most dust and water, directly preventing most dust and water from entering the gap between the cover and the battery pack interface 51, thus reducing the chance of dust and water entering the battery pack structure. Even if a small amount of dust and water enters between the outer shell 21 and the inner shell 24, it is sealed by the sealing sleeve 31 that fits with the battery pack interface 51, preventing dust and water from entering the inside of the battery pack interface 51, achieving a double-layer protection effect and achieving the advantage of good sealing performance.

[0036] The inner sleeve is fitted to the inner side of the sealing rubber sleeve 31, thereby providing support to the sealing rubber sleeve 31 through the inner sleeve, so that the sealing rubber sleeve 31 can be stably and tightly fitted, ensuring the sealing performance between the sealing rubber sleeve 31 and the battery pack interface 51, and also preventing dust and water from entering the battery pack interface 51 through the gap between the inner sleeve and the sealing rubber.

[0037] By tightly attaching the rubber sleeve and the outer sleeve to the inner and outer sides of the battery pack interface 51 respectively, the stability between the battery pack interface 51 and the plug can be improved, preventing the plug from shaking on the battery pack interface 51 and causing the gap to widen, thus ensuring the sealing performance.

[0038] During the process of installing the sealing sleeve 31 onto the inner shell 24, the inner shell 24 abuts against the chamfer 33, and the inner shell 24 can press the locking block 32 on the chamfer 33, so that the locking block 32 is squeezed and deformed and moves into the locking groove 25, which facilitates the installation of the sealing sleeve 31.

[0039] Pushing the support rod 42 causes the support block 41 to elastically deform, causing the latch 43 to move away from the inner shell 24. Then, the cover is installed on the battery pack interface 51. After releasing the support rod 42, the support block 41 causes the support rod 42 and the latch 43 to spring back, so that the latch 43 engages with the battery pack interface 51, thereby preventing the cover from slipping off the battery pack interface 51 and realizing the function of locking the battery pack interface 51 through the latch structure.

[0040] By placing the latch 43 inside the outer casing 21, the latch structure can be protected by the outer casing 21, thereby improving the service life of the latch structure and preventing damage from collisions with external objects.

[0041] The latch 43 is supported by two support rods 42 and two support blocks 41, which improves the structural strength of the latch structure.

[0042] Pressing the pressure plate 44 by hand increases the contact surface and reduces the pressure when pressing by hand, thus facilitating the pushing of the support rod 42.

[0043] When the pressure plate 44 is pushed by hand, the anti-slip protrusions 45 increase the friction between the hand and the pressure plate 44, preventing slippage when pressing the pressure plate 44 and making it easier to use. In addition, the anti-slip protrusions 45 can increase the thickness of the pressure plate 44, which can improve the structural strength of the pressure plate 44 and prevent the pressure plate 44 from being damaged under force.

[0044] The guide groove 23 cooperates with the battery pack interface 51, and the battery pack interface 51 is inserted into the guide groove 23, thereby preventing the plug from rotating on the battery pack interface 51, improving the stability of the plug, preventing the outer shell 21 from shaking and increasing the gap, and ensuring the sealing.

[0045] While pressing the pressure plate 44 with your thumb, your four fingers can rest on the pull plate 12, making it easy to apply force to the pressure plate 44 and thus making it easy to push the pressure plate 44, which is convenient to use.

[0046] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
