The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0044] like Figure 1 and Figure 2 As shown, the present invention discloses a new energy power battery management system 10, which includes a box body 20 and a cover plate 30 rotatably arranged on the box body 20, and the cover plate 30 is rotated to realize the opening and closing of the box body 20.

[0045] Please also read Figure 3 , Figure 4 and Figure 5 The new energy power battery management system 10 further includes a control device 40 mounted on the box 20. Figure 6 , Figure 7 and Figure 8As shown, the control device 40 includes: a knob 100 , a fuse 200 , and a locking mechanism 300 .

[0046] The knob 100 is turned to connect the fuse 200 to the circuit and lock the cover 30 by the locking mechanism 300; or the knob 100 is turned to disconnect the fuse 200 from the circuit and lock the cover 30 by the locking mechanism 300; or the knob 100 is turned to disconnect the fuse 200 from the circuit and unlock the cover 30 by the locking mechanism 300.

[0047] In the present invention, the problems raised by the background technology are solved mainly by setting up a control device 40: on the one hand, it is necessary to open the cover from time to time to repair and maintain the internal electrical components. Before opening the cover, it is often necessary to remove the fuse first to put the circuit in a disconnected state to avoid accidents such as electric shock or battery short circuit; on the other hand, sometimes the fuse is removed to put the circuit in a temporary disconnected state, and it is not necessary to open the cover to repair and maintain the internal electrical components. How to temporarily remove the fuse without opening the cover is a situation that needs to be considered.

[0048] For example, the knob 100 is turned to connect the fuse 200 to the circuit and the locking mechanism 300 locks the cover 30. At this time, the entire new energy power battery management system 10 is in a normal working state.

[0049] For another example, the knob 100 is turned to disconnect the fuse 200 from the circuit and lock the cover 30 by the locking mechanism 300. At this time, the fuse is removed to temporarily disconnect the circuit, and it is not necessary to open the cover to repair and maintain the internal electrical components.

[0050] For another example, the knob 100 is turned to disconnect the fuse 200 from the circuit and to allow the locking mechanism 300 to unlock the cover 30. At this time, the cover needs to be opened to perform maintenance on the internal electrical components. Before opening the cover, it is often necessary to remove the fuse first to disconnect the circuit to avoid accidents such as electric shock or battery short circuit.

[0051] Next, the specific structure of the control device 40 is described:

[0052] like Figure 7 As shown, the knob 100 has a receiving groove 110, and a notch 111 is formed on the groove wall of the receiving groove 110; the fuse 200 is curved and elastically received in the receiving groove 110, and both ends of the fuse 200 are located at the notch 111;

[0053] like Figure 7 and Figure 8As shown, the locking mechanism 300 includes: a main body 310, a locking pin 320, and an elastic member 330; the locking pin 320 is arranged on the main body 310, the main body 310 is formed with a spiral structure 311, the knob 100 is provided with a supporting rod 120 matched with the spiral structure 311, and the elastic member 330 is used to provide elastic force for the main body 310 so that the spiral structure 311 is supported on the supporting rod 120;

[0054] The cover plate 30 is provided with a lock slot 31 (such as Figure 2 As shown), the knob 100 is rotated to insert or disengage the locking pin 320 into or from the locking slot 31, and the fuse 200 is disconnected from or connected to the circuit.

[0055] like Fig. 9 As shown, more specifically, in the present invention, the circuit has a first elastic sheet 51 and a second elastic sheet 52, and the first elastic sheet 51 and the second elastic sheet 52 are located around the receiving groove 110;

[0056] like Fig. 9 As shown, the knob 100 is rotated so that the first elastic piece 51 and the second elastic piece 52 are connected to the two ends of the fuse 200 through the notch 111, or the first elastic piece 51 and the second elastic piece 52 are blocked by the groove wall of the accommodating groove 110 and disconnected from the two ends of the fuse 200.

[0057] Next, the working principle of the new energy power battery management system 10 is described in conjunction with the control device 40:

[0058] When the knob 100 is rotated forward, the abutting rod 120 on the knob 100 pushes the main body 310 (the elastic member 330 is compressed) to move forward along the axis through the spiral structure 311. Driven by the main body 310, the lock pin 320 moves forward and is inserted into the lock slot 31 to lock the cover. At the same time, the first elastic sheet 51 and the second elastic sheet 52 are connected to the two ends of the fuse 200 through the notch 111 to achieve circuit communication. The entire new energy power battery management system 10 is in a normal working state.

[0059] The knob 100 is rotated in the opposite direction by a small angle. Under the elastic action of the elastic member 330, the main body 310 moves backward along the axis, and the lock pin 320 moves backward a short distance accordingly. Since the lock pin 320 is not completely separated from the lock slot 31, the cover is still in a locked state. At this time, since the knob 100 is rotated by a small angle, the first elastic sheet 51 and the second elastic sheet 52 are blocked by the slot wall of the accommodating slot 110 and are disconnected from both ends of the fuse 200, the circuit is disconnected, and the entire new energy power battery management system 10 is in a temporary disconnected state.

[0060] Continue to rotate the knob 100 in the opposite direction to the specified position. Under the elastic action of the elastic member 330, the main body 310 moves backward along the axis, and the locking pin 320 moves backward accordingly until the locking pin 320 completely disengages from the locking slot 31, and the cover is in an unlocked state. At this time, due to the rotation of the knob 100, the first elastic sheet 51 and the second elastic sheet 52 are blocked by the slot wall of the accommodating slot 110 and disconnected from the two ends of the fuse 200, and the circuit is disconnected. The entire new energy power battery management system 10 is in a state where the cover needs to be opened to repair and maintain the internal electrical components.

[0061] like Figure 4 As shown, in the present invention, a mounting hole 21 is opened on the box body 20, and the hole wall of the mounting hole 21 forms an inner gear ring 22; the knob 100 is rotatably arranged in the mounting hole 21, and the fuse 200 has a protruding structure 210 (such as Figure 7 As shown in FIG. 1 , the protruding structure 210 extends out of the accommodating groove 110 and meshes with the inner gear ring 22. The present invention utilizes the good elasticity of the fuse 200 metal after bending, and provides the protruding structure 210 and the inner gear ring 22 matched with the protruding structure 210. During the rotation of the knob 100, the fuse 200 will undergo elastic deformation and mesh with the inner gear ring 22, forming a certain rotation resistance and making a "click-click" sound, which is conducive to the stable adjustment of the knob 100.

[0062] like Figure 4 As shown, further, a panel 23 is provided at the mounting hole of the box body 20, and the panel 23 is fastened to the mounting hole 21 of the box body 20 by bolts. The panel 23 is provided with an avoidance hole 24, and the knob 100 partially protrudes out of the avoidance hole 24. By providing a detachable panel 23, the knob 100 in the mounting hole 21 can be limited to prevent the knob 100 from being separated from the mounting hole 21; when the fuse 200 needs to be replaced, the panel 23 can be removed, the knob 100 and the fuse 200 can be easily taken out, and a new fuse 200 can be installed on the knob 100 and then returned to its original position.

[0063] Furthermore, the locking mechanism 300 further includes a support plate 340 (eg, Figure 5 As shown in FIG. 3 , the support plate 340 is used to provide support for the main body 310, the locking pin 320, and the elastic member 330. In this embodiment, the elastic member 330 is a cylindrical spring.

[0064] like Figure 8 and Fig. 9 As shown, preferably, the control device 40 further includes a locking ring 400 , and the locking ring 400 is used to lock the fuse 200 on the knob 100 .

[0065] like Fig. 9As shown, specifically, the locking ring 400 is curved in an arc shape, and a barb structure 410 is formed at both ends of the locking ring 400; a plurality of convex stops 112 are provided at the notch of the accommodating groove 110; the barb structures 410 at both ends of the locking ring 400 are abutted against the notch of the accommodating groove 110, and the ring body of the locking ring 400 is abutted against the plurality of convex stops 112, so that the locking ring 400 is fastened to the notch of the accommodating groove 110; the protruding structure 210 of the fuse 200 is pressed against the ring body of the locking ring 400, and the ring body of the fuse 200 is pressed against the barb structures 410 at both ends of the locking ring 400.

[0066] like Fig.10 As shown, when the fuse 200 needs to be replaced, the locking ring 400 needs to be removed first, and the locking ring 400 is pulled along one side of the radial direction so that the protruding structure 210 of the fuse 200 is no longer pressed on the ring body of the locking ring 400, which provides a space for the locking ring 400 to rotate; then, the locking ring 400 is rotated, so that the entire locking ring 400 can be removed from the knob 100, so that the fuse 200 can be easily taken out of the accommodating groove 110 and replaced; after the replacement of the new fuse 200 is completed, the above-mentioned actions are repeated in reverse, and the locking ring 400 can be locked on the knob 100 again, so as to fix the fuse 200.

[0067] A new energy power battery management system of the present invention effectively controls the fuse, and can remove the fuse before opening the cover plate, and can also remove the fuse without opening the cover plate.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
