Referring to fig. 1, in a bracket assembly 100 according to an embodiment of the present disclosure, a second bracket 120 may include a first longitudinal beam 121 and a second longitudinal beam 122. The first longitudinal beam 121 and the second longitudinal beam 122 are mounted on the first bracket 110, and detachably connected to the first bracket 110. The plane formed by the first longitudinal beam 121 and the second longitudinal beam 122 is parallel to the plane where the support frame 112 is located, and the plane formed by the first longitudinal beam 121 and the second longitudinal beam 122 and the plane where the support frame 112 is located form a double-layer structure, so that the second bracket 120 is mounted on the first bracket 110 to form a space similar to a shell, and after the battery box of the electric vehicle is placed on the support frame 112, the battery box can be enclosed in the shell formed by the second bracket 120 and the first bracket 110 through the second bracket 120. Here, it should be noted that the first longitudinal beam 121 and the second longitudinal beam 122 may have the same structure. Meanwhile, the main bodies of the first longitudinal beam 121 and the second longitudinal beam 122 are rod-shaped, and the longitudinal sections of the first longitudinal beam 121 and the second longitudinal beam 122 are in a shape of a Chinese character 'ji'. Therefore, when the first side member 121 and the second side member 122 are processed and prepared, the first side member and the second side member can be bent by directly using a plate material having a certain length.

Moreover, when the battery box needs to be maintained, the first longitudinal beam 121 of the second bracket 120 can be directly detached from the first bracket 110, and then the battery box can be detached from the bracket assembly 100 for maintenance. The battery box is convenient and simple, easy to realize and finally capable of effectively improving the convenience and flexibility of the disassembly and the installation of the battery box.

In one possible implementation, referring to fig. 2, the main body of the supporting frame 112 may be rectangular. By arranging the rectangular support frame 112, the structure of the support frame 112 is simplified, and the processing difficulty coefficient of the support frame 112 is reduced.

In a possible implementation manner, when the first bracket 110 is fixedly mounted on a longitudinal beam of an electric vehicle through the mounting member 115 to achieve the fixed mounting of the bracket assembly 100 of the embodiment of the disclosure on the electric vehicle, the mounting member 115 may be provided with a mounting hole.

Referring to fig. 1 to 4, the body of the mounting member 115 has a plate shape, and the number of the mounting members 115 may be set to be two or more. The installation parts 115 are parallel devices, and each installation part 115 is perpendicular to the plane of the support frame 112 and is correspondingly and fixedly installed at the connection position of the installation cross beam 111 and the support frame 112. Therefore, the second mounting hole 117 is formed on the side, which is not connected with the support frame 112, of each mounting piece 115, and the second mounting hole 117 is fixedly connected with the longitudinal beam of the electric automobile (for example, in a threaded manner), so that the structure is simple and easy to implement. Here, it should be noted that the number of the second mounting holes 117 opened on the mounting member 115 may be plural. Such as: six second mounting holes 117 may be formed in each mounting member 115. Wherein, the plurality of second mounting holes 117 may be uniformly arranged in sequence. Through setting up a plurality of second mounting holes 117, effectively improved the steadiness of bracket component 100 installation on the longeron to the reliability and the security of bracket component 100 have been improved.

Further, referring to fig. 2, in the disclosed embodiment, the first bracket 110 may further include a first triangle 118. The first triangle 118 is fixedly installed at the included angle between the installation component 115 and the installation beam 111, and is used for fixing the included angle between the reinforcement installation component 115 and the installation beam 111, so as to avoid the deformation and displacement of the installation component 115, and further improve the firmness of the bracket assembly 100.

In one possible implementation, the number of the mounting beams 111 at the hollow position of the support frame 112 may be more than two. More than two mounting beams 111 are arranged in parallel at the middle position of the support frame 112, and each mounting beam 111 is fixedly connected with the frame of the support frame 112.

For example, referring to fig. 2, as: the number of the mounting beams 111 may be two, which are a first mounting beam and a second mounting beam respectively. The first and second mounting beams are disposed in parallel and are parallel to the short borders (i.e., the first border 1120 and the second border) of the rectangular support frame 112.

Through setting up more than two installation crossbeams 111 in support frame 112's hollow position department, not only effectively reduced the space of support frame 112's hollow position department, improved the steadiness when the battery box is arranged in on support frame 112. Meanwhile, the phenomenon that the performance of a power battery system in the battery box body is influenced due to the fact that the temperature of the bottom of the battery box body is high because a whole flat plate is adopted as a plane support of the support frame 112 is avoided, and effective heat dissipation of the power battery system in the battery box body is guaranteed.

Referring to fig. 3, when the mounting beams 111 are disposed in parallel at the hollow position of the supporting frame 112, they may extend to the outside of the supporting frame 112 along the direction of the first frame or the second frame of the supporting frame 112. Therefore, when the mounting cross beam 111 extends to the outer side of the support frame 112, the clamping groove can be formed in the extending side of the mounting cross beam 111, and the clamping groove is lapped on the third frame of the support frame 112 and is fixed. The other side of the mounting cross member 111 (i.e., the side connected to the fourth frame of the supporting frame 112) is fixedly mounted on the fourth frame of the supporting frame 112 by means of screw connection.

Through adopting above-mentioned mode, compare in the hollow position department that support frame 112 was arranged in to installation crossbeam 111, directly adopt the welded mode with the mode of installing the both ends fixed mounting of installation crossbeam 111 in support frame 112, effectively improved the steadiness of installation crossbeam 111 on support frame 112, avoided installing crossbeam 111 and dropped the phenomenon that gets off by support frame 112 under the heavy pressure of battery box to the security of bracket component 100 has just also been improved further.

It should be noted that, referring to fig. 3, in the bracket assembly 100 of the embodiment of the present disclosure, a second triangle 119 may be further fixedly installed at an included angle between the installation ridge and the supporting frame 112. The second third leg plate 119 is used for fixing an included angle between the reinforcing mounting cross beam 111 and the supporting frame 112 so as to avoid the position of the mounting cross beam 111 from shifting.

Further, in the bracket assembly 100 according to the embodiment of the disclosure, the first baffle 113 and the second baffle 114 are fixedly mounted to opposite rims (i.e., the first rim and the second rim) of the supporting frame 112, and the first baffle 113 and the second baffle 114 may be symmetrically disposed with respect to a central axis of the supporting frame 112. That is, the first baffle 113 and the second baffle 114 may have the same shape and structure. Thus, when the first baffle 113 and the second baffle 114 are processed, the same process may be used as it is.

Referring to fig. 2 and 5, the planes of the first and

second baffles

113 and 114 may each be arranged in a trapezoidal shape. Meanwhile, the first and

second shutters

113 and 114 are bent into an "L" shape. The bent edge of the first baffle 113 and the bent edge of the second baffle 114 are both located on the third frame side (i.e., the same side as the mounting member) of the supporting frame 112 and are fixedly connected (e.g., welded) to the third frame. The first mounting hole 116 is disposed on both the bent edge of the first baffle 113 and the bent edge of the second baffle 114. The bent edge of the first baffle 113 and the bent edge of the second baffle 114 are fixedly connected with a longitudinal beam of the electric vehicle through a first mounting hole 116. The first baffle plate 113 and the second baffle plate 114 are bent, and the first mounting holes 116 are respectively formed in the bent edge of the first baffle plate 113 and the bent edge of the second baffle plate 114, so that the bent edge of the first baffle plate 113 and the bent edge of the second baffle plate 114 can be fixedly connected with the longitudinal beam of the electric automobile through the first mounting holes 116 (for example, the bent edge of the first baffle plate 113 and the bent edge of the second baffle plate 114 can be in threaded connection with the longitudinal beam of the electric automobile through the first mounting holes 116), and the stable mounting of the bracket assembly 100 on the electric automobile is further improved.

It should be noted that the number of the first mounting holes 116 may be set to be plural. Such as: referring to fig. 4, the number of the first mounting holes 116 may be the same as the number of the second mounting holes 117, and the distribution pattern is the same.

In addition, referring to fig. 1 and 2, the first baffle 113 and the second baffle 114 are perpendicular to the plane of the supporting frame 112. Referring to fig. 5, the first baffle 113 and the second baffle 114 are both provided with windows 1130. Window 1130 has an extended bezel that faces into the frame formed by first brace 110 and second brace 120. The first longitudinal beam 121 and the second longitudinal beam 122 are both mounted on the extending frame and are in threaded connection with the extending frame.

That is, a window 1130 is formed in each of the first bezel 113 and the second bezel 114, and then the edge of the window 1130 is turned over (the turning direction is toward the inside of the housing formed by the first bracket 110 and the second bracket 120) to form an extended frame. Moreover, by forming fixing holes on the extending frame far from the supporting frame 112, correspondingly, mounting holes matched with the fixing holes are also formed at two ends of the first longitudinal beam 121 and two ends of the second longitudinal beam 122. Therefore, when the first longitudinal beam 121 and the second longitudinal beam 122 are detachably mounted on the first bracket 110, the first longitudinal beam 121 and the second longitudinal beam 122 may be directly overlapped on the extended frames of the first baffle plate 113 and the second baffle plate 114, and the mounting holes and the fixing holes may be aligned and fastened by bolts. Simple structure to need not add other parts and can realize, simplified bracket component 100's structure, still reduced bracket component 100's processing cost simultaneously, saved the processing material.

Further, in the bracket assembly 100 according to the embodiment of the present disclosure, referring to fig. 1 and 6, the first longitudinal beam 121 and the second longitudinal beam 122 are fixedly mounted with the supporting member 123. The supporting member 123 is perpendicular to the plane of the supporting frame 112, and the supporting member 123 is supported between the first bracket 110 and the second bracket 120 for supporting the second bracket 120, so as to avoid the deformation of the second bracket 120, which further improves the stability of the bracket assembly 100.

Referring to fig. 1, two supporting members 123 may be fixedly mounted on the first longitudinal beam 121, and the two supporting members 123 are disposed in parallel. One end of each of the two supporting members 123 is fixedly connected to the first longitudinal beam 121, and the other end is fixedly connected to a connection portion between the mounting cross beam 111 and the frame of the supporting frame 112. The number of the supporting members 123 fixedly attached to the second longitudinal member 122 may be two. The two supporting members 123 are respectively disposed between the first baffle 113 and the mounting member 115, and between the second baffle 114 and the mounting member 115.

Referring to fig. 6, the main body of the supporting member 123 may be a supporting plate, and the cross section of the supporting plate is "zigzag". Therefore, when the support member 123 is fixedly mounted on the first longitudinal beam 121 and the second longitudinal beam 122, fixing holes may be directly formed in both side edges of the support member 123, mounting holes matched with the fixing holes may be formed in the first longitudinal beam 121 and the second longitudinal beam 122, and the fixing holes and the mounting holes may be aligned and then directly fastened and mounted by fastening bolts. Moreover, the cross section of the supporting member 123 is arranged to be "n" shaped, so that the supporting plate can be directly bent when the supporting member 123 is prepared and processed. The processing technology is simple and easy to realize.

Therefore, by adopting the above structure to fix the support member 123 on the first longitudinal beam 121 and the second longitudinal beam 122, not only is the stability of the support member 123 on the first longitudinal beam 121 and the second longitudinal beam 122 ensured, but also the structure of the support member 123 is simplified, thereby reducing the processing cost and the processing difficulty coefficient of the support member 123.

Accordingly, as can be understood by those skilled in the art, the fixing manner of the supporting member 123 on the supporting frame 112 is the same as or similar to the fixing manner of the supporting member 123 on the first longitudinal beam 121 and the second longitudinal beam 122, and the detailed description thereof is omitted.

In addition, it should be noted here that welding (e.g., spot welding) may also be directly adopted to weld and fix the portions of the two side edges of the supporting member 123, which are in contact with the first longitudinal beam 121 and the second longitudinal beam 122, and further description is omitted here.
