DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: Refer to the attached specification Figure 1 , 2 and 3. A new energy storage cable with a steering adjustment function, comprising: A battery cell, an insulating layer 1 and a terminal 11; a bent sleeve 2 is arranged outside the insulating layer 1; and the bent sleeves 2 are connected to each other; A stretching mechanism and a pushing mechanism are respectively provided on both sides of the bending sleeve 2; the stretching mechanism pulls two adjacent bending sleeves 2 towards each other on one side of the bending sleeve 2; the pushing mechanism pushes the two adjacent bending sleeves 2 in opposite directions on the side away from the stretching mechanism, so that the bending sleeve 2 bends with the cable.

[0020] In the present invention, the stretching mechanism includes a No. 1 block 3 and a No. 1 adjustment ring 31; a No. 1 installation groove 32 is provided at one end of the bending sleeve 2, and a No. 1 receiving groove 33 is provided at the other end of the bending sleeve 2; one end of the No. 1 block 3 is rotatably connected in the No. 1 installation groove 32; the other end of the No. 1 block 3 is slidably connected in the No. 1 receiving groove 33 of the adjacent bending sleeve 2; the No. 1 adjustment ring 31 is rotatably connected to the outside of the bending sleeve 2; the inner wall of the No. 1 adjustment ring 31 is provided with oblique tooth patterns; the two sides of the No. 1 block 3 are provided with oblique tooth shapes meshing with the No. 1 adjustment ring 31; The pushing mechanism includes a No. 2 block 34 and a No. 2 adjusting ring 35; a No. 2 mounting groove 36 and a No. 2 accommodating groove 37 are respectively provided at both ends of the bending sleeve 2; the No. 2 mounting groove 36 and the No. 1 accommodating groove 33 are located at the same end of the bending sleeve; the No. 2 accommodating groove 37 and the No. 1 mounting groove 32 are located at the same end of the bending sleeve; the No. 2 adjusting ring 35 is rotatably connected to the outer side of the bending sleeve away from the end of the No. 1 adjusting ring 31; the inner wall of the No. 2 adjusting ring 35 is provided with helical teeth; the two sides of the No. 2 block 34 are arranged to be helical teeth meshing with the No. 2 adjusting ring 35.

[0021] In the present invention, the first block 3 and the second block 34 are both configured to be arc-shaped; the first receiving groove 33 and the second receiving groove 37 are also configured to be arc-shaped.

[0022] In the present invention, when installing a cable and bending the cable, the worker first holds the two adjacent bending sleeves 2, and then rotates the No. 1 adjustment ring 31 and the No. 2 adjustment ring 35 at the same time, and the rotation directions of the No. 1 adjustment ring 31 and the No. 2 adjustment ring 35 are opposite; during the rotation of the No. 1 adjustment ring 31, the No. 1 block 3 is driven to move toward the No. 1 receiving groove 33 through the oblique teeth, so that the two ends of the No. 1 block 3 pull the two bending sleeves 2 toward the inside, and at the same time, during the rotation of the No. 2 adjustment ring 35, the No. 2 block 34 is driven to move outward from the No. 2 receiving groove 37 through the oblique teeth, so that the No. 2 block 34 pushes the other side of the two bending sleeves 2. Therefore, the present invention pulls and pushes on both sides of the bending sleeve 2 at the same time, so that the cable between the two bending sleeves 2 is bent, and the more the No. 1 adjustment ring 31 and the No. 2 adjustment ring 35 are rotated, the greater the degree of cable bending; In the present invention, the first block 3 and the second block 34 are set to be arc-shaped. Therefore, in the process of cable bending, the cable bends along the arc-shaped first block 3 after contacting it, which can make the cable bend more uniformly, reduce local stress concentration, bend more uniformly, and reduce the risk of cable damage; at the same time, the arc-shaped first block 3 can provide better guidance for the bending of the cable, ensuring that the direction and degree of bending are more in line with expectations; The present invention arranges a No. 1 block 3 and a No. 2 block 34 on both sides of the bending sleeve 2, and the No. 1 block 3 and the No. 2 block 34 respectively pull the two bending sleeves 2 and push the two bending sleeves 2, so that the bending sleeve 2 drives the cable to bend and turn, and the angle of the bending and turning is controlled by rotating the No. 1 adjustment ring 31 and the No. 2 adjustment ring 35. At the same time, the No. 1 block 3 is arranged to be an arc, so that when the cable is bent, the No. 1 block 3 guides the bending and turning of the cable, so that the bending and turning of the cable is more uniform.

[0023] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 3 , 4 In the present invention, the outer side of the insulating layer 1 is evenly fixedly connected with connecting rings 4; the connecting ring 4 is provided with a first annular groove 41.

[0024] In the present invention, a second annular groove 42 is provided on the inner wall of the bending sleeve 2; a clamping block 43 is evenly rotatably connected in the second annular groove 42, and an extrusion ring 44 is rotatably connected in the second annular groove 42; a connecting rod 45 is hinged between the extrusion ring 44 and the clamping block 43.

[0025] In the present invention, a through groove 5 is provided on the bending sleeve 2; the through groove 5 is connected to the second annular groove 42, and a fixed block 51 is slidably connected in the through groove 5; the fixed block 51 is fixedly connected to the extrusion ring 44, and the sliding track of the fixed block 51 is an arc shape.

[0026] In the present invention, the staff moves the fixing block 51 to make the fixing block 51 slide in the through groove 5. During the sliding process, the fixing block 51 drives the extrusion ring 44 to rotate, so that the extrusion ring 44 pushes the connecting rod 45, so that the engaging block 43 rotates into the first annular groove 41, and the engaging block 43 engages the connecting ring 4 and the bending sleeve 2, so that the bending sleeve is fixed on the insulating layer 1 of the cable, and the bending sleeve 2 will not slide, which will affect the bending of the cable.

[0027] In the present invention, an ejection groove 6 is provided on the bending sleeve 2; one end of the ejection groove 6 passes through the bending sleeve 2, and the other end is connected to the No. 1 receiving groove 33; an ejection block 61 is slidably connected in the ejection groove 6; the lower end of the ejection block 61 is located in the No. 1 receiving groove 33, and the end of the ejection block 61 close to the No. 1 block 3 is set in an oblique shape.

[0028] In the present invention, an ejection groove 6 is provided on the bending sleeve 2, so when the cable is bent, the No. 1 block 3 moves in the No. 1 receiving groove 33. When the No. 1 block 3 moves to the end of the No. 1 receiving groove 33, the front end of the No. 1 block 3 presses the inclined end surface of the ejection block 61, so that the ejection block 61 moves upward and extends out of the ejection groove 6. When the staff sees the ejection block 61 extending out, they know that the No. 1 block 3 has moved to the maximum distance in the No. 1 receiving groove 33, that is, the bending sleeve 2 drives the cable to bend at the maximum angle. In the present invention, three bending sleeves 2 form a group, and the three bending sleeves 2 can bend the cable between any two, thereby increasing the bending angle of the cable in the present invention; The present invention provides an ejection groove 6 and an ejection block 61 on the bending sleeve 2. Therefore, when the angle of the cable bending by the two bending sleeves 2 reaches the maximum, the No. 1 block 3 pushes the ejection block 61 to move upward to expose the ejection groove 6, thereby reminding the staff to prevent the staff from continuing to rotate the No. 1 adjustment ring 31 and the No. 2 adjustment ring 35 after the bending angle of the cable bending by the bending sleeve 2 reaches the maximum, causing the teeth between the No. 1 block 3, the No. 2 block 34 and the No. 1 adjustment ring 31, the No. 2 adjustment ring 35 to wear.
