[0042] In an embodiment, the energy storage container 1 comprises a box body 11, a wire harness structure 12 and a fixing structure 14, the box body 11 is usually made of metal material, the box body 11 is provided with a containing cavity 110, the containing cavity 110 is used for arranging battery modules and other equipment, the wire harness structure 12 is arranged in the containing cavity 110, the wire harness structure 12 is fixedly connected with the inner wall of the box body 11 through the fixing structure 14, the wire harness structure 12 is used for supporting and fixing the cable harness, ensuring that the cable 13 is arranged in order inside the energy storage container 1, and preventing the cable 13 from being abraded or damaged due to external factors such as vibration and movement.

[0043] The box 11 comprises a battery compartment 111, a compartment opening 112 in communication with the battery compartment 111, an electrical appliance compartment 113, and a compartment door (not shown in the figure). The battery compartment 111 is a space in the box 11 for accommodating a battery cluster. The battery compartment 111 is connected with external equipment or an electrical system through the compartment opening 112, facilitating the installation, maintenance, or replacement of the battery cluster. The electrical appliance compartment 113 is provided with a busbar cabinet (not shown in the figure). The compartment door is pivotally connected with the box 11 to open or close the compartment opening 112. The compartment door is used to seal or open the compartment opening 112, thereby protecting the battery cluster (not shown in the figure) and the cable 13 inside the box 11 from the influence of external environment (such as water, dust, temperature fluctuation, etc.) on the stability of the battery cluster.

[0044] The wire harness structure 12 comprises a plurality of limiting structures 121 arranged at intervals along a first direction X. The limiting structure 121 comprises a limiting arm 1211 having a limiting hole 1219 for accommodating the cable 13. The fixing structure 14 comprises a plurality of connecting pieces 141. One connecting piece 141 is arranged corresponding to one limiting structure 121. One end of the connecting piece 141 is fixedly connected with the limiting structure 121, and the other end of the connecting piece 141 is fixedly connected with the box 11. Thus, the cable 13 can be prevented from being arranged loosely, and the cable 13 can be fixed in a specific position in an orderly manner, avoiding the stacking of the cable 13, effectively improving the utilization rate of the internal space of the box 11, and realizing efficient fixing of the cable 13 and simplifying the installation process.

[0045] Meanwhile, a plurality of limiting structures 121 are arranged at intervals along the first direction X, and the plurality of limiting structures 121 are arranged in a “one-word” manner. The limiting structure 121 separates the cable 13, so that the cable 13 can be uniformly distributed on the inner wall of the box 11, avoiding the stacking of a plurality of cables 13, which is beneficial to the heat dissipation of the cable 13 and reduces the safety hazard caused by excessive temperature rise, thereby effectively improving the poor heat dissipation problem caused by the accumulation or overlap of the cable 13 in the related art. The first direction can be an X direction. Figure 2

[0046] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ; wherein, Figure 3 is a first structure diagram of a wire harness structure provided by an embodiment of the utility model; Figure 4 is an enlarged view of A in Figure 3 provided by an embodiment of the utility model.

[0047] ​In an embodiment, the limiting arm 1211 is arranged around at least part of the side wall of the cable 13, and the contact surface of the limiting arm 1211 with the cable 13 is a circular arc surface, so as to better match the circular or semicircular shape of the cable 13, provide more compact and stable support, and prevent the cable 13 from being displaced due to vibration, shaking or external force during transportation or operation; at the same time, the friction and wear between the limiting arm 1211 and the surface of the cable 13 are reduced, the service life of the cable 13 is prolonged, and the safety of the cable 13 is enhanced.

[0048] Further, the wire harness structure 12 includes a base 122, and a plurality of limiting structures 121 are arranged on the base 122, so as to enhance the stability of the wire harness structure 12 as a whole, and the side of the base 122 away from the limiting structures 121 is fixedly connected with the inner wall of the box 11, so as to ensure that the cable 13 will not move or fall off due to shaking or vibration during wiring, improve the fixing effect of the cable 13, avoid problems such as loosening and accumulation of the cable 13 during use, and improve the safety and reliability of the energy storage container 1.

[0049] Among them, one limiting arm 1211 is used to accommodate one cable 13, to ensure uniform distribution of the cables 13 and reduce mutual interference and friction between the cables 13, and the limiting arm 1211 has a limiting hole 1219 for accommodating the cable 13, so that the cable 13 can be clamped in the limiting arm 1211 through the limiting hole 1219, thereby effectively preventing the cable 13 from directly contacting the inner wall of the energy storage container 1 and reducing the risk of friction and damage; in addition, when it is necessary to install or replace the cable 13, maintenance personnel can easily insert or remove the cable 13 through the opening of the limiting structure 121 without the need to disassemble the wire harness structure 12 as a whole, thereby improving the operation efficiency, and in particular in densely arranged energy storage containers 1, the maintenance time can be significantly shortened.

[0050] Please continue to combine Figures 1 to 4 In an embodiment, the limiting arm 1211 includes oppositely arranged first and second limiting portions 12111 and 12112, the cross section of the first limiting portion 12111 in the direction perpendicular to the base 122 is an arc line, and the cross section of the second limiting portion 12112 in the direction perpendicular to the base 122 is an arc line, so as to be combined into a U-shaped limiting arm 1211 as a whole through the cooperation of the first and second limiting portions 12111 and 12112.

[0051] Specifically, the first limiting part 12111 and the second limiting part 12112 are both arc-shaped parts, and the radii of the two arc-shaped parts are towards the inside, that is, towards each other; the arc-shaped structure can have a more uniform stress distribution, reducing the wear of the cable 13 caused by local extrusion during fixing, reducing the risk of aging and damage of the cable 13, thereby reducing the probability of failure of the electrical system and improving the safety and durability of the overall system.

[0052] It can be understood that the first limiting part 12111 and the second limiting part 12112 are both arc-shaped in the direction perpendicular to the base 122, so as to better match the circular or semicircular shape of the cable 13, providing more compact and stable support, and preventing the cable 13 from being displaced due to vibration, shaking or external force during transportation or operation.

[0053] Further, the cable 13 is covered with a corrugated pipe, which has excellent pressure resistance and impact resistance. When the cable 13 is covered with the corrugated pipe, external physical damage such as impact, extrusion or friction can be effectively prevented, especially in the complex wiring environment inside the energy storage container 1, the corrugated pipe can play an additional protective role to avoid damage to the insulation layer of the cable 13; at the same time, the groove design of the corrugated pipe increases its surface area, which helps air flow, so that the cable 13 can be more effectively cooled in a high-voltage, high-current working environment, reducing the temperature rise; and after the corrugated pipe is wrapped around the cable 13, the arc surface of the limiting structure 121 can better fit the outer surface of the corrugated pipe, and the corrugated structure of the corrugated pipe also enhances the friction between the connecting piece 141 and the cable 13, thereby reducing the risk of loosening of the cable 13 and ensuring the stability of the overall assembly.

[0054] Please continue to combine Figures 1 to 4 ; in an embodiment, the first limiting part 12111 is arc-shaped at an end away from the base 122, and the second limiting part 12112 is arc-shaped at an end away from the base 122.

[0056] In the energy storage container 1, the contact part of the cable 13 with the limiting arm 1211 can be worn due to friction and long-term extrusion, thereby affecting the electrical performance; it can be understood that, in the embodiment, the first contact part 121111 is designed in a circular arc shape, and the second contact part 121121 is designed in a circular arc shape, so as to reduce the direct contact surface between the cable 13 and the limiting structure 121, reduce the friction force, and reduce the risk of wear; at the same time, the circular arc-shaped contact part provides better support for the cable 13, which helps to keep the cable 13 in a fixed position and improve the stability of the fixation.

[0057] Please continue to combine Figures 1 to 4 ; in an embodiment, the limiting structure 121 includes a support part 1212, a first side wall 1213 and a second side wall 1214, the support part 1212 is arranged between the limiting arm 1211 and the base 122, one end of the support part 1212 is connected with the limiting arm 1211, and the other end of the support part 1212 is connected with the base 122; the first side wall 1213 is arranged between the first limiting part 12111 and the base 122, one end of the first side wall 1213 is fixedly connected with the first limiting part 12111, and the other end of the first side wall 1213 is connected with the base 122; the second side wall 1214 is arranged between the second limiting part 12112 and the base 122, one end of the second side wall 1214 is fixedly connected with the second limiting part 12112, and the other end of the second side wall 1214 is connected with the base 122.

[0058] It can be understood that the support part 1212 can provide additional support force for the limiting arm 1211, enhance the fixation effect of the cable 13, and avoid displacement of the cable 13 during transportation or operation; by arranging the first side wall 1213 and the second side wall 1214, the rigidity of the limiting structure 121 can be enhanced, deformation caused by external force can be avoided, and the cable 13 can be kept in the predetermined position at all times, thereby improving the stability of the overall structure; and when the cable 13 is installed or replaced, the provided side wall design enables the maintenance personnel to conveniently contact the cable 13, thereby simplifying the operation process and improving the convenience of maintenance.

[0059] Please continue to combine Figures 1 to 4 ; in an embodiment, the limiting structure 121 further includes a first reinforcing rib 1215 and a second reinforcing rib 1216, the first reinforcing rib 1215 is arranged between the first side wall 1213 and the support part 1212, and the second reinforcing rib 1216 is arranged between the second side wall 1214 and the support part 1212.

[0060] It can be understood that the embodiment can effectively enhance the stability of the whole clamping part by adding the first and second reinforcing ribs 1215 and 1216 between the first and second side walls 1213 and 1214, thereby enhancing the load-bearing capacity of the wire harness structure 12, so that the wire harness structure 12 can better maintain its shape when subjected to external impact or vibration, and the risk of possible damage is reduced.

[0061] Further, the thickness of the first reinforcing rib 1215 is less than that of the first side wall 1213, and the thickness of the second reinforcing rib 1216 is less than that of the second side wall 1214, so that the weight of the reinforcing ribs can be effectively reduced while maintaining the necessary strength, thereby helping to improve the energy efficiency and portability of the energy storage container 1.
