[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 6 As shown, the utility model provides a power consumption detection mechanism for a lithium battery protection board, including a lithium battery protection board detector 1, a plug 2 is plugged into the outside of the lithium battery protection board detector 1, and the plug 2 is connected to a detection probe 4 through a wire 3, and also includes:

[0025] A feeding structure, which is arranged on one side of the lithium battery protection board detector 1, and an adjustment component is arranged on the feeding structure;

[0026] Among them, the feeding structure includes a fixed plate 5, the fixed plate 5 is installed on one side of the lithium battery protection board detector 1, a detection platform 6 is installed on one side of the fixed plate 5, a first fixed rod 7 is installed inside the fixed plate 5, a movable plate 8 and a first spring 9 are sleeved on the outer surface of the first fixed rod 7, a notch 10 is installed on one side of the movable plate 8, a first fixed shaft 11 is installed inside the notch 10, a clamping block 12 and a second spring 13 are sleeved on the outer surface of the first fixed shaft 11, and a fixed clamping tooth 14 is installed on one side of the fixed plate 5;

[0027] Among them, the adjustment component includes a second fixed shaft 23, which is installed inside the movable plate 8. The outer surface of the second fixed shaft 23 is sleeved with 24, and the external thread of 24 is connected to the threaded rod 15. Two connecting rods 16 are connected between the two 24. The outer surface of the connecting rod 16 is sleeved with a slider 17. The outer side of the slider 17 is hinged with two groups of clamping plates 18 through a torsion spring. The inside of the slider 17 is installed with a second fixed rod 19, and the outer surface of the second fixed rod 19 is sleeved with a limiting block 20 and a third spring 21.

[0028] The detection probe 4 is clamped by the clamping plate 18, and at the same time, through the cooperation between 24 and the second fixed shaft 23 and the cooperation between the connecting rod 16 and the slider 17, the clamping plate 18 can be driven by the slider 17 to control the movement of the detection probe 4, so that the position of the detection probe 4 can be adjusted according to the position where the lithium battery protection board is connected to the power supply. At the same time, through the cooperation between the movable plate 8 and the first fixed rod 7, the movable plate 8 can be driven to move downward, so that the end of the detection probe 4 contacts the lithium battery protection board. At this time, the elastic force of the second spring 13 drives the clamping block 12 and the fixed clamping tooth 14 to clamp the movable plate 8 to limit the position. There is no need to manually hold the detection probe 4, and it is easier to detect the power consumption of the lithium battery protection board.

[0029] One side of the clamping block 12 is provided with a chamfer, and the clamping block 12 is clamped with the fixed clamping tooth 14 .

[0030] By setting a chamfer on one side of the block 12, when the inclined surface of the block 12 is squeezed by the inclined surface of the fixed tooth 14, the block 12 will move along the outer surface of the first fixed shaft 11. At the same time, the cooperation between the block 12 and the fixed tooth 14 can limit the upward movement of the block 12.

[0031] The second spring 13 is elastically supported between the notch 10 and the block 12 .

[0032] The design of the second spring 13 allows the block 12 to have good elastic reset performance. At this time, since the second spring 13 is in a compressed state, an elastic force is applied to the block 12, thereby making the block 12 and the fixed tooth 14 fit more tightly.

[0033] One side of the limit block 20 is tooth-shaped, and the limit block 20 is meshed and connected with the tooth groove 22 .

[0034] Through the cooperation between the limit block 20 and the second fixing rod 19 , the limit block 20 can move along the outer surface of the second fixing rod 19 , and through the cooperation between the limit block 20 and the tooth groove 22 , the slider 17 can be limited.

[0035] The third spring 21 is elastically supported between the slider 17 and the limit block 20 , and the clamping plate 18 is in compression contact with the detection probe 4 .

[0036] Through the design of the third spring 21, the limit block 20 has good elastic reset performance. At this time, since the third spring 21 is in a compressed state, an elastic force is applied to the limit block 20, so that the fit between the limit block 20 and the tooth groove 22 is tighter.

[0037] The threaded rod 15 is in compression contact with the movable plate 8 , and the first spring 9 is elastically supported between the fixed plate 5 and the movable plate 8 .

[0038] Through the design of the first spring 9, the movable plate 8 has good elastic reset performance. At this time, since the first spring 9 is in a compressed state, it will apply an elastic force to the movable plate 8. When the block 12 is separated from the fixed tooth 14, the elastic force of the first spring 9 will drive the movable plate 8 to move upward, which is convenient for taking out the lithium battery protection board and continuously detecting the power consumption of the lithium battery protection board.

[0039] The working principle and use process of this utility model:

[0040] First, the staff can clamp the detection probe 4 through the clamp 18, and at the same time, the connection rod 16 can be driven to move through the cooperation between 24 and the second fixed shaft 23, and the connection rod 16 and the slider 17 can be driven to move. When the slider 17 moves, the clamp 18 will drive the detection probe 4 to move together, so that the position of the detection probe 4 can be adjusted according to the position where the lithium battery protection board is powered on, and then the movement of the slider 17 can be limited by the cooperation between the limit block 20 and the tooth groove 22 and the cooperation between the threaded rod 15 and the movable plate 8. Then the staff can press the movable plate 8 to move downward to make the end of the detection probe 4 contact with the lithium battery protection board. At this time, the elastic force of the second spring 13 will drive the block 12 to engage with the fixed tooth 14 and limit the movable plate 8, so that the staff does not need to hold the detection probe 4 for detection, which makes it easier to detect the power consumption of the lithium battery protection board.
