Description

Technical Field

[0001] This utility model relates to the field of electrode technology, and in particular to a lithium battery cover electrode structure. Background Technology

[0002] The battery cover plate terminals are a key component in the lithium battery structure, and their main function is to conduct current. The terminals are usually divided into positive and negative terminals, each playing a different role.

[0003] Chinese utility model patent CN218448170U discloses a novel cover plate for lithium batteries. This device, through the inclusion of a protective shell, a slider, and positioning bolts, facilitates the storage and protection of the electrode posts, preventing damage to the electrode posts from external impacts when the lithium battery is not in use, thus improving the lifespan of the electrode posts. Regarding the aforementioned related technology, the inventors believe the following drawbacks exist:

[0004] In actual use, although the device can store and protect the electrode posts, it is difficult to completely seal them. This makes it easy for dust to accumulate on the surface of the electrode posts when the device is not in use, which will affect the conductivity during subsequent use. To address this, we provide a lithium battery cover electrode post structure. Utility Model Content

[0005] To address the problem in the aforementioned background technology that the electrode posts are difficult to seal and protect, causing dust accumulation on their surface when idle and affecting their conductivity during subsequent use, this utility model provides a lithium battery cover plate electrode post structure.

[0006] This utility model is achieved by the following technical solution: a lithium battery cover plate electrode post structure, including a cover plate body and a protective component, wherein two sets of electrode posts are symmetrically fixedly connected on the cover plate body.

[0007] The protective assembly includes a protective shell disposed outside the electrode post and fixedly connected to the cover plate body. Two sets of covers are symmetrically and movably connected to the top of the protective shell. Vertical rods are provided on both sides of the protective shell and are fixedly connected to the cover plate body. The two sets of vertical rods are slidably connected to the same bracket. A spring is also sleeved on the outside of the vertical rods. The bracket and the covers are symmetrically hinged to a connecting rod through a hinge.

[0008] As a further improvement to the above solution, two sets of T-shaped limiting sliders are symmetrically fixedly connected to the bottom of the cover, and a T-shaped limiting groove is opened on the top of the protective shell corresponding to the position of the T-shaped limiting slider, and the T-shaped limiting groove and the T-shaped limiting slider are slidably connected.

[0009] As a further improvement to the above solution, a limiting plate is fixedly connected to the top of the vertical rod.

[0010] As a further improvement to the above solution, the bracket is designed with a U-shaped structure.

[0011] As a further improvement to the above solution, both sides of the bracket are fixedly connected with levers.

[0012] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the cover plate body and the bracket, respectively.

[0013] As a further improvement to the above solution, the shape and size of the cover are half the cross-sectional shape and size of the protective shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model allows the bracket to be pushed vertically upward by flicking the lever upward, and with the sliding engagement between the bracket and the vertical rod, the spring is stretched. Utilizing the hinged connection between the bracket, the cover, and the connecting rod, and the sliding engagement between the T-shaped limiting slider and the T-shaped limiting groove, the bracket can push both sets of covers outward simultaneously as it moves upward, facilitating the opening of the protective shell and exposing the electrode post for easy connection. Conversely, after disconnection, releasing the lever causes the spring's rebound to move both sets of covers inward simultaneously to seal the protective shell. This not only prevents damage to the electrode post from impacts but also avoids dust accumulation on its surface, making it highly practical.

[0016] 2. This utility model is simple and convenient to operate, which further improves the practicality of the device. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example 1

[0024] Please combine Figure 1-4 The lithium battery cover plate electrode structure of this embodiment includes a cover plate body 1, on which two sets of electrode posts 2 are symmetrically fixedly connected.

[0025] A protective assembly for protecting and dustproofing the electrode post 2 includes a protective shell 101 disposed outside the electrode post 2 and fixedly connected to the cover plate body 1. Two sets of covers 102 are symmetrically and movably connected to the top of the protective shell 101. Vertical rods 103 are provided on both sides of the protective shell 101 and are fixedly connected to the cover plate body 1. The two sets of vertical rods 103 are slidably connected to the same bracket 104. The bracket 104 has a U-shaped structure design. A lever plate 107 is fixedly connected to both sides of the bracket 104. A spring 105 is also sleeved on the outside of the vertical rods 103. The two ends of the spring 105 are fixed to the cover plate body 1 and the bracket 104, respectively. The bracket 104 and the cover 102 are symmetrically hinged by a connecting rod 106. Two sets of T-shaped limiting sliders 3 are symmetrically fixedly connected to the bottom of the cover 102. The top of the protective shell 101 is provided with a T-shaped limiting groove corresponding to the position of the T-shaped limiting slider 3, and the T-shaped limiting groove is slidably connected to the T-shaped limiting slider 3. This not only guides the horizontal movement of the cover 102, but also prevents the cover 102 from separating from the protective shell 101. The shape and size of the cover 102 are half the cross-sectional shape and size of the protective shell 101. When the two sets of cover 102 approach and contact each other, they can completely seal the protective shell 101.

[0026] The implementation principle of a lithium battery cover plate electrode structure in this application embodiment is as follows:

[0027] In use, by flicking the dial 107 upwards, and with the sliding engagement between the bracket 104 and the vertical rod 103, the bracket 104 can be pushed vertically upwards. At this time, the spring 105 will be stretched. Utilizing the hinged engagement between the bracket 104, the cover 102, and the connecting rod 106, and the sliding engagement between the T-shaped limiting slider 3 and the T-shaped limiting groove, the bracket 104 can push both sets of covers 102 to move outwards simultaneously when it moves upwards. This makes it easier to open the protective shell 101 and expose the electrode post 2, thus facilitating power connection. After successful power connection, simply release the dial 107. The operation is simple, convenient, and quick.

[0028] After use, push the lever 107 upwards again to open the cover 102, disconnect the guide connected to the electrode post 2, and release the lever 107 directly. At this time, the spring 105 will use its own rebound to make the two sets of covers 102 move inwards at the same time to close the protective shell 101. In this way, not only can the electrode post 2 be prevented from being damaged by collision, but also dust can be avoided from falling on its surface. Example 2

[0029] Based on Embodiment 1, this embodiment is further improved in that: a limiting plate 4 is fixedly connected to the top of the vertical rod 103, which can prevent the bracket 104 from separating from the vertical rod 103.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
