Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0025] Reference Figure 1 - Figure 2, the utility model provides an embodiment: a conductive connection structure for a new energy lithium battery, comprising a battery body 1, the outer wall of the battery body 1 is fixedly connected to a connection base 2, the upper surface of the connection base 2 is fixedly connected to a slide cylinder 3, the inner wall of the slide cylinder 3 is slidably connected to a sliding ring 4, the upper surface of the sliding ring 4 is fixedly connected to a connection column 5, a first wire groove 6 is provided inside the connection column 5, a sliding groove 7 is provided inside the connection column 5, a sliding bar 8 is slidably connected inside the connection column 5, the outer wall of the sliding bar 8 is slidably connected to the inner wall of the sliding groove 7, a second wire groove 9 is provided inside the sliding bar 8, one end of the sliding bar 8 is fixedly connected to a first sliding block 10, and a sliding assembly is arranged inside the connection base 2; the sliding assembly comprises a pressing block 12, the outer wall of the pressing block 12 is slidably connected to the inner wall of the connection base 2, the inner top wall of the pressing block 12 is fixedly connected to a first spring 11, the lower end of the first spring 11 is fixedly connected to the upper surface of the connection column 5, and the inner wall of the pressing block 12 is fixedly connected to a second sliding block 13;
[0026] Specifically, the battery body 1 plays a role of fixing the connection base 2, and the pressing block 12 is pressed. At this time, the pressing block 12 will slide along the outer wall of the connection base 2, thereby prompting the second sliding block 13 to slide downward, and the second sliding block 13 slides downward to drive the first sliding block 10 to slide upward, thereby driving the sliding bar 8 to slide on the inner wall of the sliding groove 7 inside the connecting column 5, and the sliding bar 8 slides on the inner wall of the sliding groove 7 to prompt the connecting column 5 to drive the sliding ring 4 to slide upward along the inner wall of the slide cylinder 3. When the second wire groove 9 inside the sliding bar 8 and the first wire groove 6 inside the connecting column 5 are completely overlapped, the wire is placed in the second wire groove 9, and the pressing block 12 is released at this time. Since the first spring 11 contracts due to the previous downward movement of the pressing block 12, the pressing block 12 is released at this time. The first spring 11 rebounds and drives the pressing block 12 to move upward, thereby prompting the second sliding block 13 to slide upward, so that the first sliding block 10 drives the sliding bar 8 to slide inside the connecting column 5, and the wire to be connected is stuck in the second wire groove 9, so as to achieve rapid connection of the wires.
[0027] Reference Figure 1 - Figure 2 The outer wall of the first sliding block 10 is slidably connected to the outer wall of the second sliding block 13, and a connecting cylinder 14 is fixedly connected to the upper surface of the battery body 1; a third sliding groove 15 is opened on the outer wall of the connecting cylinder 14, and a fixing block 18 is fixedly connected to the inner wall of the connecting cylinder 14;
[0028] Specifically, the battery body 1 plays a role in fixing the connecting tube 14, which can significantly improve the stability of the fixing of the connecting tube 14. The fixing block 18 is inside the connecting tube 14, and the connecting tube 14 here plays a role in fixing the fixing block 18. The third sliding block 17 slides on the inner wall of the third sliding groove 15, and the third sliding groove 15 plays a role in limiting the third sliding block 17.
[0029] Reference Figure 3 The bottom end of the fixed block 18 is fixedly connected to the second spring 16, and the bottom end of the second spring 16 is fixedly connected to the third sliding block 17; the outer wall of the third sliding block 17 is slidably connected to the inner wall of the third sliding groove 15, and the outer wall of the third sliding block 17 is fixedly connected to the second clamping cylinder 20; the outer wall of the second clamping cylinder 20 is slidably connected to the inner wall of the connecting cylinder 14, and the inner wall of the connecting cylinder 14 is fixedly connected to the first clamping cylinder 19; the outer wall of the second clamping cylinder 20 is in contact with the outer wall of the first clamping cylinder 19, and the outer wall of the first clamping cylinder 19 is slidably connected to the outer wall of the third sliding block 17;
[0030] Specifically, the connecting tube 14 has a limiting and sliding effect on the third sliding block 17. Pressing the third sliding block 17 inside the connecting tube 14 fixedly connected to the upper surface of the connecting base 2 causes the third sliding block 17 to slide on the inner wall of the third sliding groove 15, pressing the second spring 16 to contract, thereby causing the fixed block 18 to break away from the fitting state with the second engaging tube 20, wherein the fixed block 18 has a fixing effect on the second spring 16. At this time, the wire is placed between the fixed block 18 and the first engaging tube 19, and the third sliding block 17 is released, causing the second spring 16 to rebound and push the third sliding block 17 to slide on the inner wall of the connecting tube 14, thereby causing the fixed block 18 to slide on the inner wall of the connecting tube 14 to clamp the wire to be fixed.
[0031] Working principle: When the structure is needed, the pressing block 12 is pressed, and the pressing block 12 will slide along the outer wall of the connecting base 2. The battery body 1 here plays a role of fixing the connecting base 2, thereby prompting the second sliding block 13 to slide downward. The second sliding block 13 slides downward to drive the first sliding block 10 to slide upward, and then drives the sliding bar 8 to slide on the inner wall of the sliding groove 7 inside the connecting column 5. The sliding bar 8 slides on the inner wall of the sliding groove 7 to prompt the connecting column 5 to drive the sliding ring 4 to slide upward along the inner wall of the sliding cylinder 3. When the second wire groove 9 inside the sliding bar 8 and the connecting When the first wire groove 6 inside the connecting column 5 is completely overlapped, the wire is placed inside the second wire groove 9, and the pressing block 12 is released at this time. Since the pressing block 12 previously moved downward and caused the first spring 11 to contract, the pressing block 12 is released at this time, and the first spring 11 rebounds and drives the pressing block 12 to move upward, thereby prompting the second sliding block 13 to slide upward, so that the first sliding block 10 drives the sliding bar 8 to slide inside the connecting column 5, and the wire to be connected is clamped into the second wire groove 9, so as to achieve rapid connection of the wires, which can greatly simplify the electrical connection. The process of assembling and maintaining the battery can improve the convenience of maintenance. The third sliding block 17 inside the connecting cylinder 14 fixedly connected to the upper surface of the connecting base 2 is pressed to cause the third sliding block 17 to slide on the inner wall of the third sliding groove 15, pressing the second spring 16 to contract, thereby causing the fixing block 18 to break away from the fitting state with the second engaging cylinder 20, wherein the fixing block 18 fixes the second spring 16. At this time, the wire is placed between the fixing block 18 and the first engaging cylinder 19, and the third sliding block 17 is released, causing the second spring 16 to rebound and push the third sliding block 17 to slide The fixing block 18 moves on the inner wall of the connecting tube 14, thereby causing the fixing block 18 to slide on the inner wall of the connecting tube 14 to clamp the wire to be fixed, thereby achieving convenient fixation of the wire, thereby preventing the wire from being damaged due to friction or external pressure, and extending its service life. The device can not only achieve rapid connection of the wire, thereby greatly simplifying the process of battery assembly and maintenance, and improving the convenience of maintenance, but also achieve convenient fixation of the wire, thereby preventing the wire from being damaged due to friction or external pressure, and extending its service life.
