On this basis, a second mounting member 23 is further provided above the first mounting member 22, and an upper surface of the second mounting member 23 is used to directly form a mounting base for the battery 01. In the embodiment of the present application, the structural form of the second mounting member 23 is not limited, and the above-described functions can be realized in various structural forms.

For example, referring to fig. 1 to 5, in the embodiment of the present application, the second mounting piece 23 may also be provided in a plate-like structure, and the second mounting piece 23 may also be made larger in size, with the second mounting piece 23 having a portion located above the support bracket 21 and a portion located above the vehicle body side member 1. In addition, the second attachment 23 may be disposed in contact with the first attachment 22, and a portion of the second attachment 23 above the vehicle body side member 1 may be fixedly connected to the vehicle body side member 1.

In the embodiment of the present application, the manner in which the second mounting member 23 is fixedly connected to the vehicle body side member 1 is not limited, and the second mounting member 23 may be fixedly connected to the vehicle body side member 1 by various means such as welding, riveting, fastening, or bonding, for example. In addition, it is to be understood that the connection manner of the fixed connection between the second mounting member 23 and the vehicle body side member 1 may be set to be the same as or different from the connection manner of the fixed connection between the first mounting member 22 and the vehicle body side member 1, which is not limited by the embodiment of the present application.

In addition to this, the first mount 22 may be fixedly connected to the vehicle body side member 1 alone, and the second mount 23 may be fixedly connected to the vehicle body side member 1 alone; in addition, it is also possible to set the position at which the first mount 22 is fixedly connected to the vehicle body side member 1 and the position at which the second mount 23 is fixedly connected to the vehicle body side member 1 to coincide, and fixedly connect the first mount 22 and the second mount 23 to the vehicle body side member 1 by the same position.

For example, for the connection between the first mount 22 and the vehicle body side member 1 and the connection between the second mount 23 and the vehicle body side member 1 to be provided as a welded connection, the welding point or weld between the first mount 22 and the vehicle body side member 1 and the welding point or weld between the second mount 23 and the vehicle body side member 1 may be provided to coincide; referring to fig. 1 to 5, for setting the connection between the first mount 22 and the vehicle body side member 1 and the connection between the second mount 23 and the vehicle body side member 1 to be the fastener connection, the fastener hole on the first mount 22 and the fastener hole on the second mount 23 may be set to coincide, so that the first mount 22 and the second mount 23 may be fixedly connected to the vehicle body side member 1 by passing the fastener through the fastener hole on the first mount 22 and the fastener hole on the second mount 23, respectively.

On the basis, in the battery mounting assembly 2 of the vehicle body structure provided by the embodiment of the application, the first mounting piece 22 and the second mounting piece 23 are further provided with the reinforcing cavity a, so that the reinforcing effect on the first mounting piece 22 and the second mounting piece 23 can be formed by utilizing the reinforcing cavity a, the stress strength of the first mounting piece 22 and the second mounting piece 23 can be improved, and the supporting strength of the battery mounting assembly 2 provided by the embodiment of the application on the battery 01 can be improved.

For example, a protrusion may be provided at an intermediate portion of the second mounting member 23 away from the first mounting member 22, such that a gap is formed between the portion of the second mounting member 23 where the protrusion is provided and the first mounting member 22, and the gap forms a reinforcing cavity a between the first mounting member 22 and the second mounting member 23. Correspondingly, a protrusion may be provided at the middle portion of the first mounting member 22 away from the second mounting member 23, such that a gap is formed between the portion of the first mounting member 22 where the protrusion is provided and the second mounting member 23, which gap forms the reinforcing cavity a between the first mounting member 22 and the second mounting member 23.

On this basis, a protrusion far from the first mounting member 22 may be provided at the middle portion of the second mounting member 23 at the same time, and a protrusion far from the second mounting member 23 may be provided at the middle portion of the first mounting member 22, so that a gap is formed between the portion of the second mounting member 23 where the protrusion is provided and the portion of the first mounting member 22 where the protrusion is provided, and the gap forms a reinforcing cavity a between the first mounting member 22 and the second mounting member 23.

It will be appreciated that, based on the above description, the shape or number of the protrusions described above may be more specifically set, so that the shape of the reinforcing cavity a can be more adapted to the arrangement of the first mounting member 22 and the second mounting member 23.

In addition, in the embodiment of the present application, the reinforcing cavity a may be a closed cavity, or the reinforcing cavity a may be a semi-closed cavity, which is not limited in the embodiment of the present application.

With the above arrangement, in the vehicle body structure provided by the embodiment of the application, the reinforcement effect can be formed on the first mount 22 and the second mount 23 by using the reinforcement cavity a between the first mount 22 and the second mount 23 of the battery mounting assembly 2, so that the stress strength of the first mount 22 and the second mount 23 can be improved. Therefore, the battery mounting assembly 2 in the embodiment of the application can provide more stable support for the battery 01. In addition, under the condition that the weight of the storage battery 01 is fixed, the reinforcing cavity a is beneficial to the reinforcing effect of the first mounting piece 22 and the second mounting piece 23, the thicknesses of the support bracket 21, the first mounting piece 22 and the second mounting piece 23 can be set to be thinner, the use of raw materials can be reduced, and the cost is saved. Meanwhile, the quality of the storage battery mounting assembly 2 in the embodiment of the application can be lightened, the weight of the whole vehicle is facilitated, and the development trend of light weight and low carbonization of the vehicle is met.

On the basis, referring to fig. 4 and 5, in some embodiments of the present application, the second mounting member 23 includes a first abutting portion 231 and a second abutting portion 232, the first abutting portion 231 abuts against the first mounting member 22, the second abutting portion 232 is used for abutting against the battery 01, a gap is provided between the second abutting portion 232 and the first mounting member 22, and the gap between the second abutting portion 232 and the first mounting member 22 forms the reinforcing cavity a.

In the embodiment of the present application, the specific configuration of the first abutting portion 231 and the second abutting portion 232 is not limited, and it is considered that the portion of the second mounting member 23 abutting the first mounting member 22 is the first abutting portion 231, and the portion of the second mounting member 23 abutting the battery 01 is the second abutting portion 232.

For example, the second mounting member 23 may be provided in a thick plate-like structure, and a groove may be provided on the lower surface of the second mounting member 23 (i.e., the surface of the second mounting member 23 facing the side of the first mounting member 22). Thus, the portion of the lower surface of the second mounting piece 23 where the groove is not provided abuts against the first mounting piece 22, and the portion of the lower surface of the second mounting piece 23 where the groove is not provided forms the first abutting portion 231. In addition, the upper surface of the second mounting member 23 may be brought into contact with the battery 01, and the upper surface of the second mounting member 23 may form the second contact portion 232. Since the second mounting member 23 is provided with the groove, a gap is formed between the upper surface of the second mounting member 23 and the first mounting member 22 at the position where the groove is provided, and the gap forms the reinforcing cavity a.

In addition, referring to fig. 2 to 5, in some embodiments of the present application, the second mount 23 may also be provided in a thin plate-like structure. In this way, the second mounting member 23 can be punched to form the protrusions on the second mounting member 23, so that the second mounting member 23 has an uneven structure. On this basis, the projection toward the first mounting piece 22 can be used to abut against the first mounting piece 22; the protrusion toward the battery 01 is brought into contact with the battery 01. In this regard, the projection toward the first mount 22 forms the first abutting portion 231, and the projection toward the battery 01 forms the second abutting portion 232. In addition, since the second abutting portion 232 is convex toward the battery 01, a gap is provided between the second abutting portion 232 and the first mounting member 22, and thus the gap between the second abutting portion 232 and the first mounting member 22 forms the reinforcing cavity a.

As will be appreciated, referring to fig. 3, 5 and 11, since the second mounting member 23 is provided with the projection toward the first mounting member 22, the projection forms a concave structure on the second mounting member 23, and after the battery 01 is mounted on the second mounting member 23, the lower surface of the battery 01 has a gap from the position where the upper surface of the second mounting member 23 is provided with the projection. Referring to fig. 11, the above-described gap between the battery 01 and the second mount 23 also forms a reinforcing cavity a. For example, referring to fig. 3 and 11, a "U" -shaped reinforcing cavity a is formed between the battery 01 and the second mount 23.

With reference to the above description, the second mount 23 and the first and second abutting portions 231 and 232 may be provided in other configurations, as long as a gap can be formed between the second abutting portion 232 and the first mount 22, and the embodiment of the present application is not limited thereto.

In this way, by providing the first abutting portion 231 and the second abutting portion 232 on the second mount 23, and forming a support between the first mount 22 and the battery 01 by the first abutting portion 231 and the second abutting portion 232, it is possible to facilitate mounting of the second mount 23 between the first mount 22 and the battery 01. Meanwhile, according to the structural characteristics of the first abutting portion 231 and the second abutting portion 232, the reinforcing cavity a is formed by utilizing the gap between the second abutting portion 232 and the first mounting member 22, so that the second mounting member 23 in the embodiment of the application has a simple structure, and the reinforcing cavity a can be manufactured conveniently.

Further, in some embodiments of the present application, in order to increase the stability of the connection between the second mounting member 23 and the first mounting member 22, the first abutting portions 231 are further disposed in a dispersed manner, so that a plurality of portions of the second mounting member 23 abut against the first mounting member 22.

Specifically, referring to fig. 4 and 5, in the embodiment of the present application, the first abutting portion 231 includes an intermediate abutting portion 2311 and an edge abutting portion 2312, the intermediate abutting portion 2311 is located in the middle of the second mounting piece 23, and the edge abutting portion 2312 is located at the edge of the second mounting piece 23. The number of the edge contact portions 2312 is plural, and the plural edge contact portions 2312 are provided at intervals along the circumferential edge of the second mount 23.

The intermediate abutment 2311 is located in the middle of the second mount 23, and the intermediate abutment 2311 is not required to be located in the middle of the second mount 23, as long as the intermediate abutment 2311 is located at and near the middle position of the second mount 23. In addition, in the embodiment of the present application, the shape of the intermediate abutment portion 2311 is not limited, and the shape of the intermediate abutment portion 2311 is exemplified by a circle, a square, or other shapes. Specifically, a circular protrusion, a square protrusion, or another shape of protrusion or the like toward the first mount 22 may be provided in the middle of the second mount 23 to form the middle abutment 2311. For example, referring to fig. 4, 5, and 8, in some embodiments of the present application, the intermediate abutment 2311 may be shaped as a "U" with the opening of the "U" toward the body side member 1.

In addition, in the embodiment of the present application, the specific number of the edge abutment portions 2312 is not limited, and specifically, may be set according to the specific shape or size of the second mount 23, and for example, the number of the edge abutment portions 2312 may be set to any number of two or more.

For example, referring to fig. 4, the edge abutment 2312 may be formed by providing protrusions toward the first mount 22 at intervals on the circumferential edge of the second mount 23, and for this purpose, each of the individual protrusions toward the first mount 22 may be considered as one edge abutment 2312.

Thus, with the above arrangement, the connection between the second mount 23 and the first mount 22 can be reinforced with the plurality of edge abutment portions 2312. On this basis, the connection between the second mounting member 23 and the first mounting member 22 is supplemented by the intermediate abutting portion 2311, so that the effectiveness of the connection between the second mounting member 23 and the first mounting member 22 can be improved, the stability of the battery mounting assembly 2 provided by the embodiment of the application can be improved, and the battery mounting assembly 2 in the embodiment of the application can further provide more stable support for the battery 01.

On this basis, in the embodiment of the application, the distribution positions of the edge abutment portions 2312 are also specially set so that the stability of the battery mounting assembly 2 can be further improved.

Specifically, referring to fig. 4 and 5, in some embodiments of the present application, the edge abutment 2312 includes a first edge abutment 23121 provided at one end of the second mount 23 remote from the body side member 1, and a second edge abutment 23122 provided at both ends of the second mount 23 in the first direction. Here, the first direction is the extending direction of the vehicle body side member 1.

According to the foregoing description, the second mount 23 is fixedly attached to the side member 1, and for this purpose, the first edge abutment 23121 can be considered to be provided at the end of the second mount 23 opposite to the attachment position of the side member 1. In this way, the connection positions of the first edge abutment portion 23121 and the second mount 23 with the side member 1 can be reinforced with each other, and thus the degree of torsion resistance of the battery mounting assembly 2 can be increased in the direction in which the first edge abutment portion 23121 points toward the side member 1.

On the basis of this, the second edge abutment portions 23122 provided at both ends of the second mount 23 in the first direction can increase the degree of torsion resistance of the battery mounting assembly 2 in the first direction.

Therefore, in the embodiment of the application, by providing the first edge abutment portion 23121 at the end of the second mount 23 remote from the vehicle body side member 1 and the second edge abutment portion 23122 at the both ends of the second mount 23 in the first direction, the torsional strength of the battery 01 mount can be improved by the connection position of the second mount 23 to the vehicle body side member 1, the first edge abutment portion 23121, and the two second edge abutment portions 23122, and the battery mounting assembly 2 in the embodiment of the application can also be further enabled to provide a more stable support for the battery 01.

In addition, referring to fig. 5 and 8, in the embodiment of the present application, a "cross" protrusion facing the battery 01 may be provided on the second mounting member 23, and thus, the outer edge of the "cross" protrusion may be in contact with the first mounting member 22, and the protruding portion of the "cross" protrusion may be used to support the battery 01, so that a "cross" reinforcing cavity a is formed between the protruding portion of the "cross" protrusion and the first mounting member 22.

For the above example, referring to fig. 8, it can be considered that the "i" shaped projections and the "n" shaped projections form the second abutting portions 232, and the "U" shaped projections between the "i" shaped projections and the "n" shaped projections toward the first mounting piece 22 form the first abutting portions 231.

In the embodiment of the present application, the number of the reinforcing cavities a between the first mounting member 22 and the second mounting member 23 is not limited, and the number of the reinforcing cavities a may be set to one, for example, the above-described "i" -shaped projections or "cross" -shaped projections may be provided on the second mounting member 23 with reference to the above description; in addition, the number of the reinforcing cavities a may be two or more, and for example, referring to fig. 8, a cross-shaped protrusion and an i-shaped protrusion may be simultaneously provided on the second mounting member 23. More specifically, the "i" shaped protrusion may be provided on the side of the second mounting member 23 away from the vehicle body side member 1, and the "cross" shaped protrusion may be provided on the side of the second mounting member 23 closer to the vehicle body side member 1.

For example, referring to fig. 8, in the embodiment of the present application, the first mounting member 22 and the second mounting member 23 may be each provided in a plate-like structure, and a part of the structure of the first mounting member 22 is located above the vehicle body side member 1, so that a part of the structure of the first mounting member 22 located above the vehicle body side member 1 forms the first lap joint 221, and in order to increase the contact area between the first mounting member 22 and the vehicle body side member 1, the connection between the first lap joint 221 and the upper surface of the vehicle body side member 1 may be provided as a bonding connection. In addition, the partial structure of the second attachment 23 may be located above the vehicle body side member 1, so that the partial structure of the second attachment 23 located above the vehicle body side member 1 forms the second overlap portion 233, and in order to increase the contact area between the second attachment 23 and the vehicle body side member 1, the connection between the second overlap portion 233 and the upper surface of the vehicle body side member 1 and the connection between the second overlap portion 233 and the first overlap portion 221 may be provided as a bonding connection.

On the basis of this, in the embodiment of the present application, the projections of the first overlap portion 221 and the second overlap portion 233 toward the side member 1 have overlapping regions.

Further, by providing the fastener in the above-described overlapping region of the first overlap portion 221 and the second overlap portion 233, the first overlap portion 221 and the second overlap portion 233 can be simultaneously fixedly connected to the vehicle body side member 1 with the fastener.

In the embodiment of the present application, the type of the fastener in the overlapping region of the first overlap portion 221 and the second overlap portion 233 is not limited.

In this way, before the first blocking member 241 is mounted on the second mounting member 23, a neutral position is formed at the mounting position of the first blocking member 241, and the battery 01 can be mounted on the second mounting member 23 using the neutral position. The first blocking member 241 is then fastened to the second mounting member 23, and the battery 01 can be interference-mounted between the first blocking member 241 and the blocking member 24 opposite to the first blocking member 241 during the fastening of the first blocking member 241.

Through the above arrangement, the battery 01 can be mounted conveniently by using the first blocking member 241 which is fastened to the second mounting member 23, and the battery 01 is set to be interference-mounted between the first blocking member 241 and the blocking member 24 opposite to the first blocking member 241, it is possible to ensure stable mounting of the battery 01 on the battery mounting assembly 2.
