The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0035] like Figure 1 and Figure 2 As shown, a BMS bracket 10 of an embodiment includes a mounting frame 100 and a wire locking member 200. The mounting frame 100 has a connection surface 101 and a mounting area 102 on opposite sides thereof, the connection surface 101 is used to be mounted on the battery assembly, and the mounting area 102 is used to install the protection plate, so that the protection plate is connected to the battery assembly through the mounting frame 100.

[0036] like Figures 2 to 5 As shown, further, the mounting frame 100 is provided with a wire groove 103 for accommodating wires, and the wire locking member 200 is movably disposed at the opening of the wire groove 103 and is engaged with the mounting frame 100 .

[0037] like Figure 4 and Figure 5As shown, in this embodiment, before the wires are placed in the wire slot 103, the wire locking member 200 is located outside the wire slot 103, and the wire slot 103 is completely open. When installing the wires, multiple wires are gathered together to form a wire harness, and the wire harness is placed in the wire slot 103, and then the wire locking member 200 is moved to the opening of the wire slot 103, so that the wire locking member 200 is engaged with the mounting frame 100, so that the wire locking member 200 is fixed at the opening of the wire slot 103, and then the wire locking member 200 limits the multiple wires in the wire slot 103, avoiding the problem of the wires escaping from the wire slot 103.

[0038] In the above-mentioned BMS bracket 10, when the wires are loaded into the wire trough 103, the wire locking member 200 is outside the wire trough 103, thereby avoiding the problem that the wire locking member 200 hinders the wires from being loaded into the wire trough 103, so as to ensure that the wires can be normally arranged after the wire locking member 200 is added; after the wires are loaded into the wire trough 103, the wire locking member 200 is moved to the opening of the wire trough 103, so that the wire locking member 200 is engaged with the mounting frame 100, so that the wire locking member 200 is fixed at the opening of the wire trough 103 and multiple wires are locked in the wire trough 103, even if the entrance width of the wire trough 103 is greater than the diameter of the wire, the wire will not accidentally escape from the wire trough 103, so that the entrance width of the wire trough 103 is not limited by the diameter of the wire, and thus the entrance width of the wire trough 103 can be designed to be larger, so that multiple wires can be loaded into the wire trough 103 after being gathered together, that is, multiple wires can be accommodated in the wire trough 103 at one time, thereby improving the efficiency of arranging the wires.

[0039] like Figure 2 As shown, in some embodiments, the number of the wire locking members 200 is multiple, and the multiple wire locking members 200 are arranged at intervals along the extension direction of the wire groove 103. In this embodiment, the wires are locked in the wire groove 103 by multiple wire locking members 200 arranged at intervals, and there is no need to completely cover the opening of the wire groove 103, which reduces the material for locking the wires, and is conducive to reducing the manufacturing cost of the BMS bracket 10.

[0040] like Figure 5 As shown, in some embodiments, the first end of the wire locking member 200 is rotatably connected to the mounting frame 100, and the second end of the wire locking member 200 is located in the wire groove 103 and is engaged with the mounting frame 100, so that the wire locking member 200 is fixed at the opening of the wire groove 103 to lock the wire in the wire groove 103.

[0041] like Figure 5As shown, in some embodiments, the mounting frame 100 and the locking member 200 are both injection-molded structures, and the first end of the locking member 200 is connected to the mounting frame 100 by injection molding. In this embodiment, the BMS bracket 10 is obtained by injection molding, which improves the efficiency of manufacturing the BMS bracket 10, and also makes the locking member 200 elastic, so that the locking member 200 can rotate relative to the mounting frame 100.

[0042] like Figure 5 As shown, in some embodiments, the wire trough 103 has a first inner side wall 1031 and a second inner side wall 1032 that are relatively arranged, the first end of the wire locking member 200 is rotatably connected to the first inner side wall 1031, and the mounting frame 100 is provided with a clamping structure 110 on the second inner side wall 1032, and the clamping structure 110 is arranged adjacent to the opening of the wire trough 103, and the second end of the wire locking member 200 is clamped with the clamping structure 110, so that the wire locking member 200 is fixed at the opening of the wire trough 103 and is located between the first inner side wall 1031 and the second inner side wall 1032, thereby improving the blocking effect of the wire locking member 200 on the wire.

[0043] like Figure 5 As shown, in some embodiments, a snap-in groove 201 is provided at the second end of the wire locking member 200, a snap-in structure 110 is protruded from the second inner side wall 1032, and the snap-in structure 110 is snap-into the snap-in groove 201 so that the second end of the wire locking member 200 is snap-into the mounting frame 100.

[0044] like Figure 5 As shown, further, the clamping structure 110 is provided with a guiding slope 111, which is used to be slidably connected with the second end of the wire locking member 200, so that the guiding slope 111 is used to guide the second end of the wire locking member 200 to move to the clamping position, thereby reducing the resistance of the second end of the wire locking member 200 to be clamped with the mounting frame 100.

[0045] like Figure 5 As shown, further, the second end of the wire locking member 200 is provided with a contact bevel 203, and the contact bevel 203 is used for sliding connection with the guide bevel 111, thereby increasing the contact area between the second end of the wire locking member 200 and the guide bevel 111, suppressing the wear of the wire locking member 200 and the mounting frame 100, and extending the service life of the BMS bracket 10.

[0046] In other embodiments, the second end of the wire locking member 200 is provided with a snap-fitting protrusion, the snap-fitting structure 110 is a groove structure, and the snap-fitting protrusion is snap-fitted into the snap-fitting structure 110 to snap-fit ​​the second end of the wire locking member 200 to the mounting frame 100 .

[0047] like Figure 4As shown, in some embodiments, a thinning groove 202 is provided at the first end of the wire locking member 200, so that the thickness of the connection between the wire locking member 200 and the mounting frame 100 is thinner, thereby reducing the rotational resistance of the wire locking member 200, and further reducing the resistance of the second end of the wire locking member 200 to the mounting frame 100.

[0048] like Figure 4 As shown, in some embodiments, the thinning groove 202 is in an arc shape, which avoids stress concentration of the wire locking member 200 and prolongs the service life of the wire locking member 200. Further, the thinning groove 202 is opened on one side of the wire locking member 200 adjacent to the wire groove 103, and the thinning groove 202 extends to two opposite sides of the wire locking member 200, so that the thickness of the first end of the wire locking member 200 is relatively uniform.

[0049] like Figure 4 As shown, in some embodiments, the wire locking member 200 includes a connecting portion 210 and a clamping portion 220, the first end of the connecting portion 210 is rotatably connected to the mounting frame 100, the clamping portion 220 is connected to the second end of the connecting portion 210, an angle is formed between the clamping portion 220 and the connecting portion 210, and the clamping portion 220 is located in the wire groove 103 and clamped with the mounting frame 100. In this embodiment, since the angle is formed between the clamping portion 220 and the connecting portion 210, the clamping portion 220 has a larger clamping area, thereby improving the clamping stability of the wire locking member 200 and the mounting frame 100.

[0050] like Figure 4 As shown, further, the angle between the clamping portion 220 and the connecting portion 210 is 90°. Of course, the angle between the clamping portion 220 and the connecting portion 210 is not limited to 90°. For example, in some other embodiments, the angle between the clamping portion 220 and the connecting portion 210 can also be 30°, 45°, 60°, 100°, etc.

[0051] The present disclosure further provides a BMS system, including the BMS bracket 10 described in any of the above embodiments, the BMS system also includes a protection plate and a plurality of wires, the protection plate is arranged in the installation area 102, one end of each wire is connected to the protection plate, and each wire is embedded in a wire groove 103.

[0052] The present disclosure also provides a battery module, including the above-mentioned BMS system, the battery module also includes a battery assembly, and the connection surface 101 is installed on the battery assembly.

[0053] Compared with the prior art, the present invention has at least the following advantages:

[0054] 1. When the wires are loaded into the wire slot 103, the wire locking member 200 is outside the wire slot 103, which avoids the problem that the wire locking member 200 hinders the wires from being loaded into the wire slot 103, so as to ensure that the wires can be properly arranged after the wire locking member 200 is added.

[0055] 2. After the wires are loaded into the wire trough 103, the wire locking member 200 is moved to the opening of the wire trough 103 so that the wire locking member 200 is engaged with the mounting frame 100, so that the wire locking member 200 is fixed at the opening of the wire trough 103 and multiple wires are locked in the wire trough 103. Even if the entrance width of the wire trough 103 is greater than the diameter of the wires, the wires will not accidentally escape from the wire trough 103, so that the entrance width of the wire trough 103 is not limited by the diameter of the wires. Therefore, the entrance width of the wire trough 103 can be designed to be larger, so that multiple wires can be gathered together and loaded into the wire trough 103, that is, multiple wires can be accommodated in the wire trough 103 at one time, which improves the efficiency of arranging the wires.

[0056] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
