Based on the implementation manners in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0043] Referring to Figures 1-7 As shown, in the first - aspect embodiment of the present utility model, a wire clamping structure for a battery box is proposed, which includes a main body 1, a guiding sleeve 2 and a sliding sleeve 3, wherein:

[0044] The main body 1 is used to connect with the battery box 200, and the main body 1 is provided with an opening 101;

[0045] The guiding sleeve 2 is installed on the first side 102 of the opening 101 and faces the second side 103 of the opening 101, and the second side 103 is located on the opposite side of the first side 102; the guiding sleeve 2 is located at the top of the opening 101;

[0046] The sliding sleeve 3 is slidably mounted in the guiding sleeve 2 and is used to jointly form a cable slot 100 with the main body 1 and the guiding sleeve 2; the sliding sleeve 3 and the guiding sleeve 2 enclose the cable slot 100 with the bottom area of the opening 101;

[0047] The sliding sleeve 3 has the following two states:

[0048] In the first state, there is a gap 104 allowing the cable to be inserted between the sliding sleeve 3 and the second side surface 103, thereby opening the cable slot 100;

[0049] In the second state, the sliding sleeve 3 abuts against the second side surface 103 to close the cable slot 100.

[0050] The cable clip structure for the battery box proposed in this embodiment, the sliding sleeve 3 is slidably mounted in the guiding sleeve 2 and is used to jointly form a cable slot 100 with the main body 1 and the guiding sleeve 2; when it is necessary to place or remove the cable from the cable slot 100, there is a gap 104 allowing the cable to be inserted between the sliding sleeve 3 and the second side surface 103; after the cable is inserted, the sliding sleeve 3 abuts against the second side surface 103 to clamp the cable in the cable slot 100; adopting this structure, during the rework of the wire harness, it is convenient to disassemble and assemble, and the cable clip structure will not be damaged and can be reused, improving reliability.

[0051] In some embodiments, the cable clip structure further includes a compression spring 4. A guiding hole 21 for slidably connecting the sliding sleeve 3 is provided in the guiding sleeve 2. One end of the compression spring 4 abuts against the bottom of the guiding hole 21 (if the guiding hole 21 is a through hole, it abuts against the first side surface 102), and the other end of the compression spring 4 abuts against the sliding sleeve 3, so that the end of the sliding sleeve 3 away from the first side surface 102 abuts against the second side surface 103. By one end of the compression spring 4 abutting against the bottom of the guiding hole 21 and the other end of the compression spring 4 abutting against the sliding sleeve 3, so that the end of the sliding sleeve 3 away from the first side surface 102 abuts against the second side surface 103, the sliding sleeve 3 maintains the second state without applying external force, that is, the cable slot 100 is in a normally closed state. When it is necessary to place or remove the cable, an external force is applied to make the sliding sleeve 3 slide in a direction away from the second side surface 103 to form the gap 104, improving the convenience of disassembling and assembling the cable.

[0052] In some embodiments, a receiving hole 31 for placing the compression spring 4 is provided inside the sliding sleeve 3. By providing the receiving hole 31 for placing the compression spring 4 inside the sliding sleeve 3, the orientation of the receiving hole 31 is opposite to that of the guiding hole 21. The compression spring 4 is placed in the receiving hole 31. While the receiving hole 31 can guide the compression spring 4, compared with the structure where the compression spring 4 is placed outside the sliding sleeve 3, it can save space, making the structure more compact and facilitating the flexible arrangement of the wire clamping structure.

[0053] In some embodiments, the wire clamping structure further includes a wire separating plate 5, and the wire separating plate 5 is installed on the guiding sleeve 2 and located inside the wire clamping groove 100. By installing the wire separating plate 5 on the guiding sleeve 2 and locating it inside the wire clamping groove 100, the wire separating plate 5 can separate and classify different wire harnesses, organize the wire harnesses, avoid wire harness entanglement from affecting the disassembly and assembly efficiency of the wire harness, and improve reliability.

[0054] In some embodiments, the wire separating plate 5 includes a horizontal plate 51 and a vertical plate 52 that are perpendicular to each other. The horizontal plate 51 is connected to the guiding sleeve 2, and the vertical plate 52 is connected to an end of the horizontal plate 51 away from the guiding sleeve 2 and extends towards the first side surface 102. Since the gap 104 is located near the second side surface 103 and the vertical plate 52 extends towards the first side surface 102, it will not block the inserted cable, facilitating the insertion of the cable. After the cable is inserted inside the vertical plate 52, the cable can be further separated, further organizing the wire harness, avoiding wire harness entanglement from affecting the disassembly and assembly efficiency of the wire harness, and improving reliability.

[0055] In some embodiments, the cross-section of the main body 1 is in a "C" shape. The main body 1 includes a bottom plate 11, a first side plate 12, and a second side plate 13 that enclose the opening 101. The first side plate 12 and the second side plate 13 are relatively and parallelly arranged on both sides of the bottom plate 11. The guiding sleeve 2 is installed at an end of the first side plate 12 away from the bottom plate 11 and faces the second side plate 13. The first side surface 102 is located on the first side plate 12, and the second side surface 103 is located on the second side plate 13. The guiding sleeve 2, the sliding sleeve 3, the first side plate 12, the bottom plate 11, and the second side plate 13 together enclose the wire clamping groove 100. By installing the guiding sleeve 2 at an end of the first side plate 12 away from the bottom plate 11 and facing the second side plate 13, the internal space of the wire clamping groove 100 can be made as large as possible, so that more cables can be clamped, improving the practicality of the device.

[0056] In some embodiments, the wire clamping structure further includes a connection base 6 mounted on the battery box 200, and the bottom plate 11 is detachably connected to the connection base 6. By mounting on the battery box 200 through the connection base 6 and detachably connecting the bottom plate 11 to the connection base 6, it is convenient for the installation and disassembly of the wire clamping structure and the battery box 200, improving the assembly and maintenance efficiency.

[0057] In some embodiments, the connection base 6 includes a base body 61 and two clamping grooves 62, and the two clamping grooves 62 are respectively connected to both sides of the base body 61; clamping portions 111 are provided on both sides of the bottom plate 11, and the clamping portions 111 are clamped in the clamping grooves 62. By providing the clamping grooves 62 on both sides of the base body 61, the clamping grooves 62 are formed by the arc-shaped plate and the base body 61, and the two sides of the bottom extend outwards respectively to form the clamping portions 111, and the clamping portions 111 are clamped in the clamping grooves 62, realizing the detachable connection between the connection base 6 and the bottom plate 11, thereby facilitating the installation and disassembly of the wire clamping structure and the battery box 200, and improving the assembly and maintenance efficiency.

[0058] In some embodiments, the connection base 6 further includes a limit support 63, and the limit support 63 is connected to the bottom of the base body 61 to support the first side plate 12. By connecting the limit support 63 to the bottom of the base body 61 and the limit support 63 supporting below the first side plate 12, on the one hand, it can carry the main body 1, and can limit the sliding of the bottom plate 11 on the connection base 6, improving the reliability of the device.

[0059] The working principle of the wire clamping structure for the battery box is as follows: When it is necessary to place or take out the cable in the cable slot 100, an external force is applied to make the sliding sleeve 3 slide in a direction away from the second side 103, so that there is a gap 104 allowing the cable to be placed between the sliding sleeve 3 and the second side 103; after the cable is placed, the pressure of the compression spring 4 makes the end of the sliding sleeve 3 away from the first side 102 abut against the second side 103, clamping the cable in the cable slot 100; adopting this structure, during the rework of the wire harness, it is convenient to disassemble and assemble, and the wire clamping structure will not be damaged and can be reused, improving the reliability.

[0060] In the second aspect embodiment of the present invention, a battery pack is provided, in combination with Figure 6 and Figure 7 as shown, including a battery box 200 and the wire clamping structure for the battery box described in the first aspect embodiment, and the main body 1 is connected to the battery box 200. Specifically, the connection base 6 is mounted on the battery box 200, and the bottom plate 11 is detachably connected to the connection base 6.

[0061] The battery pack provided in this embodiment is installed on the battery box 200 through a wire clip structure. The wire clip structure fixes the wire harness. When the wire harness is reworked, it is convenient to disassemble and assemble, improving the assembly efficiency. Moreover, the wire clip structure will not be damaged and can be reused, improving the reliability.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
