DETAILED DESCRIPTION

[0033] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0034] Example 1

[0035] like Figure 1-Figure 7 As shown, in this embodiment, a lithium battery BMS safety monitoring device is provided, including a shell 1, a connection groove 101 is provided on one side of the shell 1, a socket 2 is provided in the connection groove 101, a protection component 3 for protecting the socket 2 is installed inside the connection groove 101, and the protection component 3 includes a frame 301, two guide rails 302 and a slide plate 303, the frame 301 is fixed inside the connection groove 101, and locking bolts 5 are provided at the four corners of the frame 301, and the threaded ends of the locking bolts 5 are engaged and connected to the side walls of the connection groove 101, so that the frame 301 is fixed inside the connection groove 101; the two guide rails 302 are fixedly installed in parallel on the frame 301, and the two guide rails 302 are respectively located on both sides of the socket 2; the slide plate 303 is used to cover the socket 2, the slide plate 303 is arranged on the two guide rails 302, and the slide plate 303 slides along the length direction of the guide rails 302;

[0036] Working process:

[0037] When the lithium battery BMS safety monitoring device is not in use, or when it is not connected to a battery or other equipment, the slide plate 303 on the sliding protection assembly 3 makes it in a closed state, and then covers the top of the socket 2, which effectively prevents dust, moisture or other contaminants from entering the socket 2;

[0038] The slide plate 303 slides on two parallel guide rails 302, which are fixed on the frame 301 and are respectively located on both sides of the socket 2, ensuring that the slide plate 303 can slide smoothly along the length direction of the guide rails 302, thereby achieving the function of covering and exposing the socket 2;

[0039] When the lithium battery BMS safety monitoring device needs to be connected to a battery or other device, the user can manually push the slide plate 303 to slide along the guide rail 302 to move it away from above the socket 2, thereby exposing the socket 2. In this way, the user can insert the connecting wire into the socket 2 to complete the connection with the battery or other device.

[0040] A driving block 304 is fixed in the middle of the outer surface of the slide plate 303. The additional driving block 304 allows the user to more conveniently push the slide plate to slide along the guide rail 302. Plug connectors 305 are fixed on both upper and lower sides of the driving block 304. Two plug slots 306 are correspondingly provided on the upper and lower side walls of the frame 301. The two plug connectors 305 are movably connected to the inside of the corresponding plug slots 306 through the clamping assembly 6.

[0041] The plug connectors 305 fixed on the upper and lower sides of the drive block 304 match the plug slots 306 on the frame 301. When the slide plate 303 slides to a position covering the socket 2 or exposing the socket 2, the corresponding plug connector 305 will be inserted into the corresponding plug slot 306. In order to ensure that the slide plate 303 can be firmly locked, the function of the snap-in assembly 6 is to achieve stable snap-in of the plug connector 305 in the plug slot 306. When the plug connector 305 is inserted into the plug slot 306, the snap-in assembly 6 is locked to prevent the slide plate 303 from sliding accidentally. When the user needs to open the slide plate to expose the socket 2, he only needs to unlock the snap-in assembly 6 and then push the drive block 304 to make the slide plate 303 slide.

[0042] like Figure 1-Figure 4 as well as Figure 6As shown, in order to fix the slide plate 303 in two states, namely, in a state of protecting the socket 2 and in a state of sliding the slide plate 303 to one side of the socket 2 so as to expose the socket 2, the clamping assembly 6 includes a dark groove 601, which is provided inside the slide plate 303; a movable block 602 is slidably connected inside the dark groove 601 through a spring 603, a pressing portion is provided in the middle of the movable block 602, and the pressing portion penetrates the side wall of the driving block 304 and extends to the outside; a clamping block 604 is fixed on the side wall of the movable block 602, and two clamping blocks 604 penetrate the side wall of the corresponding plug connector 305 and are movably clamped with the clamping slot of the corresponding plug slot 306;

[0043] The locking state of the card assembly 6: when the slide plate 303 slides to the position of covering the socket 2 or exposing the socket 2, the plug connector 305 will be inserted into the corresponding plug slot 306. At this time, due to the action of the spring 603, the movable block 602 will pop outward, so that the card block 604 is tightly engaged with the card slot in the plug slot 306, ensuring the stability of the slide plate 303 when covering the socket 2 or exposing the socket 2;

[0044] Unlocked state of the card-connecting assembly 6: Press the pressing part of the movable block 602, and the pressing force will overcome the elastic force of the spring 603, so that the movable block 602 moves inward, thereby driving the card block 604 to disengage from the card slot of the plug-in slot 306. At this time, the slide plate 303 can slide along the guide rail 302, so that the slide plate 303 can switch between the two states of covering the socket 2 and exposing the socket 2.

[0045] like Figure 4 , Figure 5 As shown, in order to enable the slide plate 303 to slide along the two guide rails 302, the two ends of the slide plate 303 are connected to the corresponding guide rails 302 through the sliding assembly 4 respectively, and the sliding assembly 4 includes an ear block 401, a slide groove 402 and a slider 403. The ear block 401 is fixedly connected to the end of the slide plate 303, and the ear block 401 is slidably connected to the guide rail 302; the slide groove 402 is opened on the side wall of the guide rail 302 along the length direction of the guide rail 302; the slider 403 is fixed on the side wall of the ear block 401, and the slider 403 slides inside the slide groove 402.

[0046] like Figure 1 As shown, in order to achieve fixed installation of the housing 1 , a side plate 102 is fixedly connected to the outer side of the housing 1 , and a fixing groove 103 is formed on the side plate 102 .

[0047] Embodiment 2

[0048] like Figure 3 , Figure 5 and Figure 7As shown, on the basis of the first embodiment, in order to further prevent dust, moisture or other contaminants from entering the jack 2, a cover plate 7 is slidably connected to the inner wall of the slide plate 303, a plurality of guide posts are fixed on the side wall of the cover plate 7, the axis of the guide posts is perpendicular to the surface of the cover plate 7, the cover plate 7 is connected to the slide plate 303 through the guide posts and slides, a pressure post 8 is fixed at the middle of both ends of the cover plate 7, a guide groove 9 is opened on the side wall of the guide rail 302, the pressure post 8 is slidably connected to the inside of the guide groove 9, and one end of the guide groove 9 is inclined toward the groove wall of the connecting groove 101;

[0049] When the lithium battery BMS safety monitoring device is not in use, or when it is not connected to a battery or other equipment, the slide plate 303 on the sliding protection assembly 3 is used to cover the top of the socket 2. During this process, the cover plate 7 slides with the slide plate 303, and the pressure column 8 slides along the guide groove 9. When the slide plate 303 covers the top of the socket 2, the pressure column 8 slides to one end of the groove wall of the guide groove 9 that is inclined to connect the groove 101. Through the guiding action of the pressure column 8, the cover plate 7 slides on the slide plate 303 toward the connecting groove 101, causing the cover plate 7 to be tightly attached to the groove wall of the connecting groove 101, further preventing dust, moisture or other contaminants from entering the socket 2.

[0050] A sealing gasket 10 is disposed around one side of the cover plate 7 close to the connection groove 101 . The sealing gasket 10 seals the periphery of the cover plate 7 to increase the sealing effect, thereby increasing the protection effect of the jack 2 .

[0051] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents.
