[0031] Embodiment 1

[0032] As Figure 3-4As shown, this embodiment provides a battery pack plug-in protective cover detection device, including an indicator light 10, a sensing mechanism 20, an electrical control cabinet 30 and a support platform 40, wherein the electrical control cabinet 30 is respectively connected to the indicator light 10 and the sensing mechanism 20, and the indicator light 10, the sensing mechanism 20 and the electrical control cabinet 30 are all fixed on the support platform 40.

[0033] The indicator light 10 can be a two-color indicator light within the understanding of those skilled in the art. When the two-color indicator light detects that the PACK battery pack installation plug-in protective cover is qualified, the indicator light will display a green light; when the PACK battery pack installation plug-in protective cover is unqualified or not installed, the indicator light will display a red light and beep to remind the inspection personnel.

[0034] The indicator light 10 used in this embodiment is a three-color indicator light, and the power line of the three-color indicator light is directly connected to the power supply. The red, yellow and green lines of the three-color indicator light are light signal lines (not shown) connected to the electrical control cabinet 30, and the orange line (not shown) is a sound line connected to the buzzer (not shown).

[0035] When this detection device detects that the PACK battery pack has been installed with a plug-in protective cover and it is qualified, the three-color indicator light will show green light. When the detection battery pack has not been installed with the plug-in protective cover, the three-color indicator light will show red light, accompanied by a roaring alarm sound to remind the detection personnel. When the detection battery pack has been installed with a plug-in protective cover, but the installation is not appropriate, the three-color indicator light will show yellow light, accompanied by a roaring alarm sound to remind the detection personnel.

[0036] The sensing mechanism 20 includes a telescopic component 21, an adapter block 22 and a pressure sensing component 23. The telescopic component 21 is a cylinder. The adapter block 22 is connected to the telescopic end of the cylinder. The adapter block 22 is welded to the telescopic end of the cylinder. The adapter block 22 is in the shape of a convex block. The adapter block 22 includes a protruding portion (not shown) and a rectangular portion (not shown). One side of the rectangular portion is welded to the telescopic end of the cylinder. The top of the protruding portion is connected to the pressure sensing component 23. The pressure sensing component 23 is a pressure sensor. The pressure sensor is fixed to the middle of the top of the protruding portion of the adapter block 22 by bolts. The cylinder of the sensing mechanism 20 is connected to the electrical control cabinet 30 through an air circuit.

[0037] The detection device obtains pressure sensing information through the contact between the pressure sensor of the sensing mechanism 20 and the interface of the PACK battery pack, and then transmits the pressure sensing information to the three-color indicator light through the electrical control cabinet 30. The three-color indicator light displays different colors or is accompanied by a roaring alarm sound, thereby determining whether the PACK battery pack is installed with a plug-in protective cover. The detection device avoids the direct or other indirect costs caused by false detection due to visual fatigue in manual detection.

[0038] likeFigure 4 As shown in the figure, the detection device of this embodiment has 3 groups of induction mechanisms 20, which correspond one by one to the interfaces for detecting the battery pack. The number of groups of the induction mechanisms 20 in this detection device is determined according to the actual interfaces for detecting the PACK battery pack. The induction mechanisms 20 of this detection device can be installed in multiple groups to adapt to the interfaces of the PACK battery pack. Therefore, this detection device can meet the installation detection of the plug protection sleeves of PACK battery packs of different specifications and models according to the actual situation, and has a relatively low manufacturing cost and high modification versatility.

[0039] The shape of the electrical control cabinet 30 is a cube. The electrical control cabinet 30 is connected to the three-color indicator light and the cylinder of the induction mechanism 20 through circuits and air paths respectively. And the electrical control cabinet 30 arranges the connected circuits and air paths inside the electrical control cabinet 30. The electrical control cabinet 30 contains PLC components and can realize automatic induction detection execution, saving the man-hours of manual detection operations and improving the detection efficiency.

[0040] The support table 40 is a rectangular parallelepiped frame. The support table 40 has upper and lower layers of table surfaces (not marked in the figure) and four feet (not marked in the figure). The three-color indicator light is vertically fixed on the upper table surface of the support table 40. The bottom end of the three-color indicator light is fixed on the upper table surface by bolts and is located in the middle of 2 groups of induction mechanisms 20 and on one side of the upper table surface.

[0041] The induction mechanism 20 is fixed on the table surface of the support table 40. The cylinder is fixed on the upper table surface. The cylinder is horizontally fixed on the upper table surface by bolts. The adapter block 22 and the pressure sensor 23 are fixed on the upper table surface by connecting with the cylinder. The 3 groups of induction mechanisms 20 of this embodiment are arranged side by side and fixed on the upper table surface. And the distance between the middle induction mechanism 20 and the induction mechanisms 20 on both sides is different. As Figure 4 shown, the distance between the middle induction mechanism 20 and one side induction mechanism 20 is longer because the distances of the 3 interfaces of the PACK battery pack are different. In this embodiment, the three-color indicator light is fixed in the middle with a longer distance, making reasonable use of the support table 40.

[0042] The electrical control cabinet 30 is fixed on the lower table surface of the support table 40. The electrical control cabinet 30 is fixed at a corner of the lower table surface by anchor bolts (not marked in the figure).

[0043] As Figure 4 shown, the support table 40 is at the same height as the equipment of the PACK battery pack production line. The detection device is installed at the end of the production line. The pressure sensor of the detection device and the interface of the PACK battery pack are on the same plane. Then, the cylinder drives the pressure sensor to contact the interface of the PACK battery pack to detect whether the PACK battery pack is installed with a plug protection sleeve.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
