The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] As Figure 1 and Figure 2 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 open and close the box body 20.

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

[0046] Rotate the knob 100 to connect the fuse 200 to the circuit and lock the locking mechanism 300 to the cover plate 30; or rotate the knob 100 to disconnect the fuse 200 from the circuit and lock the locking mechanism 300 to the cover plate 30; or rotate the knob 100 to disconnect the fuse 200 from the circuit and unlock the locking mechanism 300 from the cover plate 30.

[0047] In the present invention, by mainly setting the control device 40, the problems raised in the background art are solved: on the one hand, the cover plate needs to be opened irregularly for maintenance of the internal electrical components. Before opening the cover plate, it is often necessary to first remove the fuse to keep the circuit in a disconnected state to avoid accidents such as electric shock to personnel or battery short - circuit. On the other hand, sometimes the fuse is removed to keep the circuit in a temporarily disconnected state, rather than opening the cover plate for maintenance of the internal electrical components. How to temporarily remove the fuse without opening the cover plate is a situation that needs to be considered.

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

[0049] Another example, rotate the knob 100 to disconnect the fuse 200 from the circuit and lock the locking mechanism 300 to the cover plate 30. At this time, the fuse is removed to keep the circuit in a temporarily disconnected state, rather than opening the cover plate for maintenance of the internal electrical components;

[0050] Still another example, rotate the knob 100 to disconnect the fuse 200 from the circuit and unlock the locking mechanism 300 from the cover plate 30. At this time, it is necessary to open the cover plate for maintenance of the internal electrical components. Before opening the cover plate, it is often necessary to first remove the fuse to keep the circuit in a disconnected state to avoid accidents such as electric shock to personnel or battery short - circuit.

[0051] Next, the specific structure of the above - mentioned control device 40 will be described:

[0052] As Figure 7 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 in an arc shape and is elastically received in the receiving groove 110, and both ends of the fuse 200 are located at the notch 111;

[0053] As 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 provided on the main body 310, the main body 310 is formed with a spiral structure 311, and the knob 100 is provided with a holding rod 120 that mates with the spiral structure 311. The elastic member 330 is used to provide an elastic force for the main body 310 so that the spiral structure 311 abuts against the holding rod 120;

[0054] A locking groove 31 (as shown in Figure 2 ...) is formed on the cover plate 30 and mates with the locking pin 320. Rotating the knob 100 causes the locking pin 320 to insert into or disengage from the locking groove 31, and at the same time disconnects or connects the fuse 200 to the circuit.

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

[0056] As shown in Figure 9 ..., rotating the knob 100 causes the first elastic piece 51 and the second elastic piece 52 to connect to both ends of the fuse 200 through the notch 111, or causes the first elastic piece 51 and the second elastic piece 52 to be blocked by the groove wall of the accommodating groove 110 and disconnect from both ends of the fuse 200.

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

[0058] Rotating the knob 100 in the forward direction, the holding rod 120 on the knob 100 will push 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 locking pin 320 moves forward accordingly and inserts into the locking groove 31 to lock the cover plate. At the same time, the first elastic piece 51 and the second elastic piece 52 connect to both ends of the fuse 200 through the notch 111 to achieve circuit connection, and the entire new energy power battery management system 10 is in a normal working state;

[0059] Rotating the knob 100 in the reverse 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 locking pin 320 moves backward a short distance accordingly. Since the locking pin 320 has not completely disengaged from the locking groove 31, the cover plate remains locked. At this time, since the knob 100 is rotated by a small angle, the first elastic piece 51 and the second elastic piece 52 are blocked by the groove wall of the accommodating groove 110 and disconnect from both ends of the fuse 200, the circuit is disconnected, and the entire new energy power battery management system 10 is in a temporarily disconnected state;

[0060] Continue to rotate the knob 100 in the reverse 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 groove 31. The cover plate is in the unlocked state. At this time, due to the rotation of the knob 100, 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 both 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 plate needs to be opened to repair and maintain the internal electrical components.

[0061] As Figure 4 shown, in the present invention, an installation hole 21 is formed in the box body 20, and the inner wall of the installation hole 21 forms an internal gear ring 22; the knob 100 is rotatably arranged in the installation hole 21, and the fuse 200 has a protruding structure 210 (as Figure 7 shown). The protruding structure 210 extends out of the accommodating groove 110 and meshes with the internal gear ring 22. The present invention utilizes the characteristic that the fuse 200 has good elasticity after being bent, and sets the protruding structure 210 and the internal gear ring 22 that cooperates with the protruding structure 210. During the rotation of the knob 100, the fuse 200 will undergo elastic deformation and mesh with the internal gear ring 22, forming a certain rotational resistance and can emit a "click-click-click" sound, which is beneficial to the stable adjustment of the knob 100.

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

[0063] Further, the locking mechanism 300 further includes a support plate 340 (as Figure 5 shown) installed on the inner wall of the box body 20. The support plate 340 provides 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] As Figure 8 and Figure 9 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] As Figure 9As shown, specifically, the locking ring 400 is arc-shaped and bent, and the two ends of the locking ring 400 form barb structures 410; several convex blocks 112 are provided at the notch of the accommodating groove 110; the barb structures 410 at the two ends of the locking ring 400 abut against the notch of the accommodating groove 110, and the ring body of the locking ring 400 abuts against several convex blocks 112, so that the locking ring 400 is fastened at the notch of the accommodating groove 110; the protruding structure 210 of the fuse 200 presses on the ring body of the locking ring 400, and the ring body of the fuse 200 presses on the barb structures 410 at the two ends of the locking ring 400.

[0066] As Figure 10 shown, when the fuse 200 needs to be replaced, first, the locking ring 400 needs to be disassembled. Pull the locking ring 400 along one side in the radial direction so that the protruding structure 210 of the fuse 200 no longer presses on the ring body of the locking ring 400, which provides an avoidance space for the rotation of the locking ring 400; then, rotate the locking ring 400. Thus, the entire locking ring 400 can be removed from the knob 100. In this way, the fuse 200 can be easily taken out from the accommodating groove 110 and replaced; when the replacement of the new fuse 200 is completed, reverse the above actions, 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 not only remove the fuse before opening the cover plate, but also remove the fuse without opening the cover plate.

[0068] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
