As shown in fig. 1 to 3, the edge beam for a battery pack of the present embodiment may include a main body 1, the main body 1 being formed with a connection portion for connection with a case and a mounting recess 10 for placing a wire harness 6. Hereinafter, a specific structure of the above-described mechanism for a side sill of a battery pack according to the present invention will be described in detail.

In the present embodiment, as shown in fig. 1, the main body 1 is one of the constituent members of the lower case of the battery pack 5, and is configured in a shape of a rectangular parallelepiped, so that it is possible to facilitate the improvement of the tightness and stability of the connection between the main body 1 and other members, such as the upper case, and the main body 1 and the upper case are connected to form a receiving space adapted to the battery pack 5, so that the stability and safety of the battery pack 5 when it is used can be ensured by disposing the battery pack 5 in the receiving space. In the present embodiment, the main body 1 is made of an alloy section, preferably an aluminum alloy section, which has high plasticity, good sealing performance, and long service life, and is an optimal choice for the main body 1 in the present embodiment.

In order to achieve the above-mentioned connection effect of the main body 1, a connection portion including the connection plate 20 and the weight-reduction recess 23 is formed at the top of the main body 1, and it should be noted that the connection portion is provided at the top of the main body 1, that is, at a side of the main body 1 facing the upper case, in consideration of the angle at which the main body 1 in the present embodiment is a component of the lower case, that is, the main body 1, and the upper case are connected. Specifically, as shown in fig. 1 to 3, the connecting portion is formed with a weight-reduction recess 23 opened in a direction away from the battery pack 5 above a side portion of the main body 1 facing away from the battery pack 5, the weight-reduction recess 23 extends in a longitudinal direction of the main body 1 and penetrates opposite ends of the main body 1, and the weight-reduction recess 23 is provided such that the connecting portion is formed with the connecting plate 20 above the weight-reduction recess 23. That is, the bottom of the connecting plate 20 is the upper side of the opening of the weight-reduction recess 23 (see fig. 2), and the top of the connecting plate 20 is the top of the main body 1. Further, in the present embodiment, as shown in fig. 1, both ends of the connection plate 20 are formed with chamfers to facilitate connection of the main body 1 with other members such as a cross member and the like.

The specific position of the weight-reduction recess 23, the shape and size of the opening thereof, and the like are not particularly required, and it is sufficient if the weight-reduction effect can be exerted on the main body 1 to reduce the weight of the main body 1 and the installation of the mounting hole 21 described below can be facilitated. For example, as shown in fig. 2, the shape of the opening portion of the weight-reduction recess 23 may be a U-like shape in the present embodiment, and the length of the upper side portion may be larger than that of the lower side portion, so as to match the position of the mounting hole 21 described below, so as to facilitate the penetration of the mounting hole 21.

In addition, as shown in fig. 1, a plurality of mounting holes 21 are formed at intervals on the top of the connecting plate 20 to connect the main body 1 with the upper case, and each mounting hole 21 penetrates into the opening of the weight-reduction recess 23, so that accumulation of, for example, aluminum chips generated during the boring process in the mounting hole 21 can be prevented, and fastening of a connector such as a bolt can be facilitated, which is advantageous for enhancing the fastening property of the main body 1 after being connected with the upper case. With the arrangement, if the threaded fastening glue is accumulated at the bottom of the mounting hole 21, namely the bottom of the connecting plate 20, in the fastening process of the connector such as a bolt, a producer can clean the accumulated fastening glue in time through the weight-reducing concave part 23, so that the labor intensity of the producer is effectively reduced. It should be noted that the mounting holes 21 in this embodiment are all threaded holes, and the threads in the mounting holes 21 are formed by extruding with a tool such as an extrusion tap, and this machining method does not break the streamline of the threads, so that the threads have high connection strength, and the connection strength between the main body 1 and the upper housing is further effectively increased. However, the form of the mounting hole 21 is not limited thereto, and may be, for example, a pin hole, in which case the connecting member is correspondingly provided as a pin, as long as the stability of the connection between the main body 1 and the upper case can be ensured. In addition, the number, position, and spacing of the mounting holes 21 are not particularly required, and are determined according to the actual situation, such as the number, position, and spacing of the mounting holes of the upper housing.

In addition, in the present embodiment, as shown in fig. 1 to 2, the connecting portion further includes a sealing recess 22, which can be used for placing a sealing member such as a sealing strip, thereby ensuring the sealing property in the space where the battery pack 5 is located when the main body 1 is connected to the upper case. Specifically, the sealing recess 22 is L-like in shape, and is formed at the opposite side of the top of the main body 1 to the side where the connecting plate 20 is formed and extends along the length direction of the main body 1, that is, the top of the main body 1 is formed in a step structure, the higher part of the step structure is the connecting plate 20, and the lower part is the sealing recess 22. The shape of the sealing recess 22 is not limited to this, and may be, for example, a U-like shaped recess that is open toward the top facing away from the main body 1, and in this case, the sealing recess 22 may be capable of accommodating a sealing member such as a weather strip, that is, the sealing recess 22 may be sufficient as long as the sealing property at the joint of the main body 1 and the upper case can be enhanced. Similarly, the size, position, and the like of the seal recess 22 are not particularly limited as long as the sealing effect can be ensured.

Further, in the present embodiment, as shown in fig. 1 to 3, a mounting recess 10 opened toward the battery pack 5 is formed on a side of the main body 1 facing the battery pack 5, and the mounting recess 10 is used for placing the wire harness 6, so that the wire harness 6 does not need to be arranged in the middle of the battery pack 5 (as shown in fig. 4), but is disposed around the battery pack 5, thereby making the layout of the battery pack 5 more reasonable, that is, the middle passage of the battery pack 5 does not need to occupy a space in the height direction. The mounting recesses 10 penetrate opposite ends of the main body 1 in a longitudinal direction of the main body 1 to facilitate installation of the wiring harness 6 to avoid interference of the wiring harness 6 with members such as the main body 1 or the battery pack 5 during the installation. Further, as shown in fig. 1 to 2, both side portions of the open portion of the mounting recess 10 are respectively inclined toward the side edges of the main body 1 located on the same side thereof, so that the opening width of the mounting recess 10 is larger than the width of the bottom of the mounting recess 10, that is, the cross-section of the open portion of the mounting recess 10 is in a ladder-like shape, and the bottom thereof and the side where the opening is located are respectively formed as the shorter side and the longer side of the cross-section of the ladder-like shape. The arrangement is such that the mounting recess 10 has a wide range of use, thereby being applicable to mounting of different types of wire harnesses 6; in addition, the arrangement can facilitate the operation of a producer when installing the wire harness 6, thereby effectively improving the production efficiency and reducing the labor intensity of the producer.

It should be noted that the installation position of the installation recess 10 is not particularly limited, and is determined according to actual conditions, such as the direction of the wire harness 6. Further, the size of the opening portion of the mounting recess 10, for example, the degree of inclination of both side portions thereof, etc., is also not particularly limited as long as the mounting of the wire harness 6 can be facilitated. However, the width of the bottom of the open portion of the mounting recess 10 should be not less than the diameter of the wire harness 6, so that the wire harness 6 can be stably fixed, and at the same time, both sides of the open portion of the mounting recess 10 can be prevented from contacting or pressing the wire harness 6, so as not to affect the operation of the wire harness 6 in the subsequent operation process.

Further, in the present embodiment, as shown in fig. 1, a plurality of fixing holes 11 for fixing the wire harness 6 are formed at intervals in the bottom of the opening portion of the mounting recess 10. Specifically, as shown in fig. 3, a frame member 12 for fixing the wire harness 6 is provided in the fixing hole 11, and one end of the frame member 12 is formed into a screw structure corresponding to the fixing hole 11, so that the frame member 12 can be fixed in the mounting recess 10; the other end of the frame member 12 is formed into a ring-shaped snap structure, so that the wire harness 6 is fixed by disposing the snap around the outer periphery of the wire harness 6. However, the form of the frame member 12 is not limited thereto as long as it can stably fix the wire harness 6 in the mounting recess 10.

Further, in the present embodiment, as shown in fig. 1 to 2, the main body 1 is further formed with a plurality of lightening grooves 40, and each lightening groove 40 extends in the length direction of the main body 1 and penetrates both ends in the length direction of the main body 1, thereby achieving a light weight of the main body 1. The size, number, and the like of the lightening grooves 40 are not particularly required, and the purpose of lightening the body 1 can be achieved while ensuring sufficient bearing capacity of the body 1. Further, a first convex portion 30 is formed at a side of the main body 1 facing away from the battery pack 5, and the first convex portion 30 is formed with a plurality of fitting holes for fitting the battery pack 5, where the first convex portion 30 is formed as a flat support portion having a frame structure as shown in fig. 2. The number, position, etc. of the fitting holes are not particularly limited as long as the stability of the assembly of the battery pack 5 can be facilitated. Further, a second projection 31 for connecting one of the members of the bottom plate, i.e., the lower case, is formed at the bottom of the side of the main body 1 facing the battery pack 5, where as shown in fig. 2, the second projection 31 may be formed as a support portion having a stepped structure, and the size and the like of the second projection 31 are not particularly limited as long as the stability after the bottom plate connection can be secured to facilitate the arrangement of the battery pack 5. The connection manner of the bottom plate and the second convex portion 31 is not limited, and the bottom plate and the second convex portion may be connected by welding, for example.

According to the edge beam for the battery pack of the present invention as described above, the wire harness 6 can be mounted and fixed by the mounting recess 10 formed at the side of the main body 1 facing the battery pack 5, so that the running direction of the wire harness 6 and the arrangement of the battery pack 5 are more reasonable; in addition, by providing the weight-reduction recess 23 below the connection plate 20, the strength of the connection of the main body 1 with the upper case is greatly enhanced, and the cleaning of the mounting hole 21 is made easier, thereby effectively reducing the labor intensity of a manufacturer. And the arrangement of a plurality of lightening slots 40 ensures that the main body 1 has stronger bearing capacity and simultaneously ensures that the main body 1 has high lightening degree.
