[0055] As Figure 1 As shown, a specific embodiment of the present utility model provides an acupuncture device. The acupuncture device includes a box body 100, a bottom plate component 200, a pressing plate component 300, and at least one temperature monitoring component 400 or / and a pressure monitoring component 500.

[0056] Among them, the bottom plate component 200 is arranged inside the box body 100 and is used to place the battery pack. The pressing plate component 300 is arranged on the side of the bottom plate component 200 facing the battery pack, and the pressing plate component 300 is used to squeeze the battery pack. The temperature monitoring component 400 is arranged on the side of the bottom plate component 200 away from the battery pack; the temperature monitoring component 400 is used to monitor the temperatures at different positions around the acupuncture site of the battery pack. The pressure monitoring component 500 is arranged on the side of the pressing plate component 300 facing the battery pack; the pressure monitoring component 500 is used to monitor the pressures at different positions around the acupuncture site.

[0057] In this embodiment, by arranging at least one temperature monitoring component 400 on the side of the bottom plate component 200 away from the battery pack, the temperature monitoring component 400 can be used to monitor the temperatures at different positions around the acupuncture site of the battery pack, which is convenient for recording the changes in the temperature around the acupuncture site of the battery pack with distance and time. By arranging the pressure monitoring component 500 on the side of the pressing plate component 300 facing the battery pack, the pressure monitoring component 500 can be used to monitor the pressures at different positions around the acupuncture site, which is convenient for recording the changes in the pressure around the acupuncture site of the battery pack with distance and time. It effectively solves the problem that the existing acupuncture devices cannot monitor the changes in pressure or temperature around the acupuncture site.

[0058] It should be noted that the acupuncture site refers to the position where the battery pack is punctured by the puncture needle 710.

[0059] As Figure 4As shown, in some embodiments, the temperature monitoring component 400 includes a plurality of temperature monitoring units 410, and the plurality of temperature monitoring units 410 are arranged in a direction away from the acupuncture site. By arranging the plurality of temperature monitoring units 410 in a direction away from the acupuncture site, it is possible to monitor the temperature at positions having different distances from the acupuncture site, so as to obtain the change of temperature with distance. For the same monitoring position, it is also possible to obtain the change of temperature with time.

[0060] It should be noted that at least two are defined as a plurality.

[0061] It can be understood that in this embodiment, the number of the temperature monitoring components 400 is not limited. The number of the temperature monitoring components 400 can be one, two, three, four, five, etc. Specifically, when the number of the temperature monitoring components 400 is not less than three, three temperature monitoring components 400 can be arranged around the acupuncture site evenly.

[0062] In some embodiments, the acupuncture device includes two temperature monitoring components 400, and the two temperature monitoring components 400 are symmetrically arranged on both sides of the acupuncture site. With the acupuncture site as the center, the two symmetrically arranged temperature monitoring components 400 can be used to monitor the temperature at different positions on the same circumference, improving the accuracy of the temperature monitoring result.

[0063] It can be understood that in the two temperature monitoring components 400, the gap between two adjacent temperature monitoring units 410 in the first temperature monitoring component 400 is the first gap, and the gap between two adjacent temperature monitoring units 410 in the second temperature monitoring component 400 is the second gap. Preferably, the first gap is equal to the second gap.

[0064] Specifically, the temperature monitoring unit 410 includes but is not limited to a temperature sensor.

[0065] As Figure 4 As shown, in some embodiments, the pressing plate component 300 has a needle-passing hole 311; the pressure monitoring component 500 includes a thin-film pressure sensor 510, and the thin-film pressure sensor 510 is provided with a through hole, and the through hole corresponds to the needle-passing hole. Using an existing thin-film pressure sensor to test the pressure simplifies the structure of the pressure monitoring component 500.

[0067] In some other embodiments, the pressure monitoring component 500 includes at least one pressure monitoring assembly; the pressure monitoring assembly includes a plurality of pressure monitoring units; the plurality of pressure monitoring units are arranged at intervals in a direction away from the acupuncture site. The pressure monitoring at different positions of the battery pack can be realized through the pressure monitoring units.

[0068] As Figure 2 and Figure 3 shown, the box body 100 includes a frame 110, which is composed of aluminum profiles. A front side plate 101 is provided on the front side of the frame 110. A hollowed-out area is formed on the front side plate 101, and a transparent viewing window 120 is installed in the hollowed-out area, which is convenient for observing the battery pack. A door body 130 is provided on the rear side of the frame 110, which is convenient for inspecting the internal structure of the box body 100 and for taking and placing the battery pack. Upper side plates 102, lower side plates 103, left side plates 104 and right side plates 105 are respectively provided on the upper side, lower side, left side and right side of the frame 110.

[0069] Further, the left side plate 104 or / and the right side plate 105 are provided with mounting holes, and a smoke exhaust fan 800 is installed in the mounting holes. When the smoke in the box body 100 is large, the smoke exhaust fan 800 can be turned on to extract the smoke in the box body 100, so that the operator can observe the battery pack through the transparent viewing window 120.

[0070] Further, wheels 150 are provided at the lower end of the frame 110. By providing the wheels 150, it is convenient to move the needle punching device.

[0071] Further, a partition plate 140 is also provided in the box body 100, and the partition plate 140 divides the internal cavity of the box body 100 into an upper cavity and a lower cavity. The transparent viewing window 120 communicates with the upper cavity, and the smoke exhaust fan 800 is used to exhaust the smoke in the upper cavity.

[0072] Further, the needle punching device further includes a mobile power source 900, and the mobile power source 900 is arranged in the box body 100. Specifically, the mobile power source 900 is arranged in the lower cavity, and the mobile power source 900 is used to supply power to the electrical components of the needle punching device. By providing the mobile power source 900, the needle punching device can work outdoors, expanding the applicable scenarios of the needle punching device.

[0073] As Figure 1 shown, in some embodiments, the bottom plate component 200 includes a bottom plate 210 and a support block 220; the bottom plate 210 is used to place the battery pack; the support block 220 is placed on the partition plate 140 and is used to support the bottom plate 210 so that the bottom plate 210 is within the viewing range of the transparent viewing window 120, ensuring that the operator can clearly see the battery pack on the bottom plate 210 through the transparent viewing window 120.

[0074] In some implementations, the needle punching device further includes a pressing plate driving structure 320; the pressing plate driving structure 320 is connected to the pressing plate component 300 and is used to drive the pressing plate component 300 to move towards the battery pack to squeeze the battery pack. Compared with manually driving the pressing plate component 300, the method of using the pressing plate driving structure 320 to drive the pressing plate component 300 is more labor-saving.

[0075] AsFigure 3 and Figure 5 As shown in Figure 5 , in some embodiments, the pressing plate component 300 includes a pressing plate; the pressing plate has a needle-passing hole 311 for the needle 710 of the needle-punching component 700 to pass through. The pressing plate driving structure 320 is connected to the pressing plate and is used to drive the pressing plate to move in the needle-punching direction to squeeze the battery pack. When the battery pack needs to be needle-punched, the pressing plate driving structure 320 drives the pressing plate to move towards the battery pack in the needle-punching direction to squeeze the battery pack, so that the battery pack is clamped by the bottom plate 210 and the pressing plate; then the needle 710 of the needle-punching component 700 passes through the needle-passing hole 311 to needle-punch the battery pack.

[0076] As Figure 3 shown in Figure 3 , further, the pressing plate driving structure 320 includes a handwheel 321 and a lead screw 322; the handwheel 321 is connected to the lead screw 322, the lead screw 322 is rotationally matched with the upper side plate 102 of the box body 100, and the lead screw 322 is rotationally matched with the connecting component 610 through a ball. Rotating the handwheel 321, the handwheel 321 drives the lead screw 322 to rotate relative to the box body 100 and the connecting component 610, and then drives the pressing plate to move downward through the pressure relief component 600, so that the pressing plate presses against the battery pack.

[0077] It should be noted that in the specific embodiments of the present invention, the needle-punching direction can be the up-down direction, the front-back direction, or the left-right direction. In the specific embodiments of the present invention, the needle-punching direction is not limited.

[0078] Specifically, the bottom plate 210 is located below the pressing plate, and the pressing plate driving structure 320 is connected to the pressing plate and is used to drive the pressing plate to move up and down.

[0079] As Figure 1 、 Figure 3 、 Figures 5 to 7 shown in Figures 5 to 7 , in some embodiments, the needle-punching device further includes a pressure relief component 600; the pressure relief component 600 is arranged in the box body 100, one end of the pressure relief component 600 is connected to the pressing plate driving structure 320, and the other end is in sliding fit with the pressing plate component 300 in the needle-punching direction; before the battery pack is needle-punched, the pressure relief component 600 drives the pressing plate component 300 to squeeze the battery pack; when the battery pack expands, the pressing plate component 300 drives the pressure relief component 600 to move away from the battery pack to achieve pressure relief. By providing the pressure relief component 600 that is in sliding fit with the pressing plate component 300, the battery pack can be tightly pressed before the battery pack is needle-punched; when the battery pack expands, the energy generated by the explosion of the battery pack can be absorbed to achieve pressure relief and reduce the loss caused by the explosion of the battery pack.

[0080] Further, the pressure relief component 600 includes a connection component 610, a guide component 620, and a buffer component 630; the connection component 610 is connected to the platen driving structure 320, one end of the guide component 620 is connected to the connection component 610, and the other end forms a limit boss 621. The platen component 300 is provided with a sliding hole along the needle-punching direction, and the guide component 620 is inserted into the sliding hole and is in sliding fit with the sliding hole; the limit boss 621 is located on the side of the platen component 300 facing the battery pack. The buffer component 630 is disposed between the platen and the connection component 610; before the battery pack is needle-punched, the platen driving structure 320 drives the platen to press the battery pack through the pressure relief component 600; when the battery pack expands, the platen drives the buffer component 630 to move away from the battery pack to achieve pressure relief. By providing the guide component 620 that is in sliding fit with the platen component 300, it can be ensured that the platen component 300 can tightly press the battery pack, and it can also be ensured that when the battery pack expands, it can move upward. By providing the buffer component 630, the energy released by the explosion of the battery pack can be absorbed, and the loss caused by the explosion of the battery pack can be reduced.

Preferably, the guide component includes a guide rail provided on the inner side surface of the box body 100 and a slider provided on the connection component 610, and the slider is in sliding fit with the guide rail along the needle-punching direction.

[0082] Further, the number of the guide components 620 is at least two, and the two guide components 620 are symmetrically disposed on both sides of the needle-passing hole 311. Preferably, the number of the guide components 620 is four, and the four guide components 620 are arranged around the needle-passing hole 311. The connection component 610 is further configured to be connected to the four guide components 620, and the platen driving structure 320 can synchronously drive the four guide components 620 through the connection component 610.

[0083] Further, the connection component 610 includes two first connection plates and a second connection plate; the two connection plates are arranged in parallel and spaced apart on both sides of the needle-passing hole 311, and each first connection plate is in sliding fit with two guide components 620 respectively. The two ends of the second connection plate are connected to the two first connection plates, and the platen driving structure 320 is connected to the second connection plate.

[0084] Further, the buffer component 630 includes an elastic member or / and a hydraulic buffer.

[0085] As Figure 5As shown, preferably, the elastic member includes a spring. The spring is sleeved on the guide member 620, and the upper end of the spring is connected to the first connecting plate of the connecting assembly 610, and the lower end of the spring is connected to the pressing plate. If the battery pack expands during the acupuncture process, the spring is compressed and contracts to absorb energy, causing the battery pack to release pressure and avoiding the explosion risk caused by hard limits.

[0086] As Figure 6 and Figure 7 shown, preferably, the hydraulic buffer is arranged between the pressing plate and the second connecting plate of the connecting assembly 610. The upper end of the hydraulic buffer is connected to the second connecting plate of the connecting assembly 610, and the lower end of the hydraulic buffer abuts against the pressing plate. If the battery pack expands during the acupuncture process, the hydraulic buffer is compressed and contracts to absorb energy, causing the battery pack to release pressure and avoiding the explosion risk caused by hard limits.
