[0040] like Figures 1 to 3As shown, in some embodiments, a battery system includes a battery module 100, a housing 200, a wiring harness bracket 300, and a fixing member 400. The battery module 100 is disposed in the housing 200. The housing 200 includes a crossbeam 210 and a longitudinal beam 220, and the crossbeam 210 and the longitudinal beam 220 are connected. One end of the wiring harness bracket 300 is connected to the crossbeam 210, and the other end is connected to the longitudinal beam 220. The wiring harness bracket 300 is provided with a wire groove 310 for accommodating a wire harness 311, and the wire groove 310 is located at the connection between the crossbeam 210 and the longitudinal beam 220. The fixing member 400 is connected to the wiring harness bracket 300 and is disposed at the opening of the wire groove 310.

[0041] It should be noted that the fixing member 400 can secure the wire harness 311 within the wire trough 310, preventing the wire harness 311 from escaping from the trough 310. The wire harness 311 of the battery system is housed within the wire trough 310 of the wire harness bracket 300, preventing the wire harness 311 from contacting the sharp edges and corners of the battery case 200, thereby avoiding the risk of wire abrasion and improving the reliability and safety of the battery system's electrical signal connections. The corners of the case 200 can be the junctions between the crossbeam 210 and the longitudinal beam 220 of the case 200.

[0042] In some embodiments, the battery system also includes a battery management system 500 (Battery Management System, BMS for short). The battery management system 500 is electrically connected to the battery module 100. The connecting wiring harness 311 of the battery management system 500 can be accommodated in the wiring trough 310 of the wiring harness bracket 300. The wiring harness 311 generally includes wires for connecting the individual battery cells of the battery module 100, and wires for connecting to external devices (such as the battery management system 500, charging interface, etc.). The wiring trough 310 provides a dedicated accommodation space for these wiring harnesses 311, so that the wiring harnesses 311 can be neatly arranged, avoiding the wiring harnesses 311 from being distributed in a disorderly manner inside the battery system. This not only helps to improve the cleanliness inside the battery system, but also facilitates the management and maintenance of the wiring harness 311.

[0043] Specifically, the depth of the wire trough 310 can be 13.5 mm. The height can be 19 mm. The wire trough 310 can accommodate at least 130 0.35 mm 2 The battery module has 100 sampling lines, which can meet the number of sampling signals required.

[0044] In some embodiments, one end of the wire harness bracket 300 is detachably connected to the crossbeam 210. The other end of the wire harness bracket 300 is detachably connected to the longitudinal beam 220. This arrangement facilitates installation and removal of the wire harness bracket 300. When assembling the battery system, one end of the wire harness bracket 300 can be first connected to the crossbeam 210, then the position of the wire harness bracket 300 can be adjusted and the other end of the wire harness bracket 300 can be connected to the longitudinal beam 220, facilitating installation.

[0045] Furthermore, since the battery system may require maintenance, repair, or component replacement, the detachable connection facilitates separate operation of the wiring harness bracket 300 without damaging the entire structure of the box 200. For example, if the wiring harness bracket 300 is damaged, it is easy to remove it for repair or replacement.

[0046] Specifically, the wire duct 310 bracket can be connected to the crossbeam 210 or the longitudinal beam 220 through a sheet metal clip.

[0047] In some embodiments, a first support member 320 is provided at one end of the wiring harness bracket 300, extending toward the crossbeam 210. The first support member 320 is connected to the crossbeam 210 at the end away from the wiring harness bracket 300. The first support member 320 is used to strengthen the connection between the wiring harness bracket 300 and the crossbeam 210, enhance the load-bearing capacity and vibration resistance of the wiring harness bracket 300, and prevent the wiring harness bracket 300 from loosening or detaching from the crossbeam 210 when subjected to external forces (such as vibrations from the battery system or bumps during vehicle driving).

[0048] Specifically, the battery system includes a first connector 330. A first mounting hole is defined in the first support member 320, with one end of the first connector 330 being secured within the first mounting hole. A first mounting plate 211 is provided on the side of the crossbeam 210 facing the wiring harness bracket 300. The other end of the first connector 330 forms a first clamping portion 331, which is clamped onto the first mounting plate 211. Specifically, the crossbeam 210 may be a cavity structure.

[0049] It should be noted that the snap-on and clamping connection of the first connector 330 makes the installation process relatively simple. When assembling the battery system, the installer can first snap one end of the first connector 330 into the first mounting hole, and then simply clamp the first clamping portion 331 onto the first mounting plate 211. This connection method does not require complex tools or special installation techniques, improving installation efficiency.

[0050] In some embodiments, a second support member 340 is provided at the other end of the wiring harness bracket 300, extending toward the longitudinal beam 220. The second support member 340 is connected to the longitudinal beam 220 at one end of the wiring harness bracket 300. The second support member 340 is used to strengthen the connection between the wiring harness bracket 300 and the longitudinal beam 220, enhance the load-bearing capacity and vibration resistance of the wiring harness bracket 300, and prevent the wiring harness bracket 300 from loosening or detaching from the longitudinal beam 220 when subjected to external forces (such as vibrations from the battery system or bumps during vehicle driving). Specifically, the longitudinal beam 220 can be provided with a slotted structure.

[0051] In some embodiments, the battery system includes a second connector 350. A second mounting hole is defined at the other end of the second support member 340, and one end of the second connector 350 is secured within the second mounting hole. A second mounting plate 221 is provided on the side of the longitudinal beam 220 facing the harness bracket 300. The other end of the second connector is a second clamping portion 351, which is clamped onto the second mounting plate 221.

[0052] It should be noted that the snap-on and clamping connection of the second connector 350 makes the installation process relatively simple. When assembling the battery system, the installer can first snap one end of the second connector 350 into the second mounting hole, and then simply clamp the second clamping portion 351 onto the second mounting plate 221. This connection method does not require complex tools or special installation techniques, thereby improving installation efficiency.

[0053] Specifically, the first mounting plate 211 and the second mounting plate 221 are arranged at an angle, and correspondingly, the first clamping portion 331 and the second clamping portion 351 are arranged at an angle.

[0054] More specifically, the first mounting plate 211 and the second mounting plate 221 are disposed perpendicularly to each other. Correspondingly, the first clamping portion 331 and the second clamping portion 351 are disposed perpendicularly to each other.

[0055] It should be noted that when the first mounting portion is clamped on the first mounting plate 211 and the second mounting portion is clamped on the second mounting plate 221, the translation of the first support member 320 and the second support member 340 can be effectively limited, that is, the translation of the wiring harness bracket 300 can be limited, avoiding unnecessary displacement of the wiring harness bracket 300, causing the wiring harness bracket 300 to loosen, so that the wiring harness bracket 300 is firmly set on the crossbeam 210 and the longitudinal beam 220 of the box body 200.

[0056] In some embodiments, a relief opening 230 is defined on the box body 200 , and the harness bracket 300 has a bending portion disposed in the relief opening 230 .

[0057] It should be noted that the crossbeam 210 and longitudinal beam 220 of the box body 200 are arranged perpendicularly or at an angle, and the wire harness bracket 300 needs to be bent to enable the wire harness bracket 300 to be connected to the crossbeam 210 and longitudinal beam 220. When the bent portion is embedded in the avoidance opening 230, the space inside the box body 200 can be more effectively utilized without increasing the overall volume of the box body 200.

[0058] In some embodiments, a plurality of fixing members 400 are provided, and the plurality of fixing members 400 are spaced apart and arranged at the opening of the wire groove 310 .

[0059] The fixing member 400 is provided at the opening of the wire trough 310 to prevent the wire harness 311 from escaping from the wire trough 310. During the operation of the battery system, the wire harness 311 may be displaced due to factors such as the vibration of the vehicle and the working vibration of the battery system itself. The fixing member 400 can firmly fix the wire harness 311 in the wire trough 310 to ensure the stable position of the wire harness 311. At the same time, it can also protect the wire harness 311 and prevent external objects (such as the edges and corners of other components) from causing scratches, wear and other damage to the wire harness 311. Multiple fixing members 400 correspond to different positions of the fixed wire harness 311 to enhance the fixing effect of the wire harness 311.

[0060] In some embodiments, the wiring harness bracket 300 includes a first end plate and a second end plate, which are arranged opposite to each other and enclose a wiring groove 310. One end of the fixing member 400 is connected to the first end plate, and the other end is provided with a hook. The second end plate is provided with a slot, and the hook is locked in the slot.

[0061] During operation, the operator first places the wire harness 311 in the wire trough 310, then aligns the hook of the fixing member 400 with the slot of the second end plate and gently presses to secure the wire harness 311. When maintenance, replacement, or inspection of the wire harness 311 is required, the hook is removed from the slot to open the fixing member 400, allowing easy removal of the wire harness 311. Compared to the cable tie method used in related art, this structure is more convenient and improves the efficiency of securing the wire harness 311.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
