Referring to fig. 1, a universal battery frame 100 according to an embodiment of the present invention includes a frame upright 11 and a battery mounting bracket 12. The frame upright 11 is fixed on the vehicle body and comprises two parallel upright posts arranged at intervals. The battery mounting frame 12 includes a mounting frame 121 formed by two fixing beams 1211 connected with two connecting beams 1212, the mounting frame 121 is connected to the frame upright 11, and the upper surface configuration thereof forms a mounting surface S for mounting a battery (not shown). One end of each fixed beam 1211 is connected to one of the frame posts 11, and the other end is suspended. Meanwhile, the two fixed beams 1211 are parallel and located on the same horizontal plane, and the two connecting beams 1212 are connected in parallel and spaced between two ends of the two fixed beams 1211.

The universal battery frame 100 has a simple structure, and the non-integral design does not need to be larger than the battery to be mounted in size, so that the size is easy to control, and the occupied space is reduced. In addition, the non-integral design also makes the universal battery frame 100 have no special requirement on the size of the battery in terms of installation adaptability, and the two ends of the battery can exceed the universal battery frame 100. Therefore, the universal battery frame 100 has low requirements for the size of the battery, can adapt to batteries with different sizes, and has strong universality. The mounting frame 121 composed of the fixing beams 1211 and the connecting beams 1212 also provides the universal battery frame 100 with a stable structure without affecting the versatility.

Specifically, each frame upright 11 includes a middle section 111, a first edge 112, and a second edge 113, and the first edge 112 and the second edge 113 are respectively formed by extending edges of two opposite sides of the middle section 110 in directions away from each other, so that each frame upright 11 is shaped like a Chinese character 'ji' with an opening facing away from the battery mounting frame 12 as a whole. The frame pillar 11 in the shape of a Chinese character 'ji' has a first edge 112 and a second edge 113 for connecting with a vehicle body while having a good structural strength.

In this embodiment, the first edge 112 and the second edge 113 are both provided with a plurality of mounting holes 114, when mounting, an installer fixes bolts to the mounting holes 114 of the first edge 112 and the second edge 113, so that the frame upright 11 can be fixed on the vehicle body, and the mounting and dismounting are convenient. It is understood that rivet connection, welding, etc. may be used in other embodiments, and are not limited in particular.

More specifically, the fixing beam 1211 and the connecting beam 1212 are both of a slot-type structure with an opening facing away from the mounting surface S. The fixing beams 1211 and the connecting beams 1212 adopt a groove-shaped structure, so that the weight of the fixing beams 1211 and the strength of the connecting beams 1212 are greatly reduced, and the strength of the fixing beams is not influenced too much. The groove-shaped opening faces away from the mounting surface S, so that the mounting surface S formed in the mode is smoother, and the contact area of the mounting surface S and a battery is larger.

Further, the battery mounting frame 12 further includes four beam reinforcements 122, the four beam reinforcements 122 are respectively mounted at four corners of the mounting frame 121, and two ends of each beam reinforcement 122 are respectively connected to one fixing beam 1211 and one connecting beam 1212. The cross beam reinforcement 122 structurally reinforces the mounting frame 121 under the condition that the mounting space is not influenced, and the reinforced mounting frame 121 has stronger deformation resistance and stable and reliable work.

In some embodiments, the universal battery frame 100 further includes a plurality of braces 13, and each brace 13 has one end connected to the frame upright 11 and another end connected to a side of the fixed cross member 1211 facing away from the mounting surface S. In this way, the inclined strut 13 is installed on the side away from the installation surface S, and the inclined strut 13 supports the fixed cross beam 1211 to enhance the load-bearing capacity of the installation frame 121 without affecting the spatial structure on the installation surface S, so that the inclined strut 13 does not limit the installation size of the battery.

In this embodiment, there are two diagonal braces 13, and both ends of each diagonal brace 13 are respectively connected to the connected frame upright 11 and fixed cross beam 1211. The diagonal brace 13 is a groove shape having an opening on one side, and the opening faces the fixed cross member 1211.

Further, the universal battery frame 100 further includes a support 14, the support 14 includes a base 141, the base 141 includes a first section 1411 and a second section 1412 bent relative to the first section 1411, the first section 1411 is disposed on the frame upright 11 along the longitudinal direction of the frame upright 11, and the second section 1412 is disposed on the fixing cross-beam 1211 along the longitudinal direction of the fixing cross-beam 1211. The support 14 reinforces the connection of the fixed cross-beam 1211 with the frame upright 11.

Further, the support 14 further includes a reinforcement plate 142, the reinforcement plate 142 being connected between the first section 1411 and the second section 1412. The edge of the second segment 1412 and the reinforcing plate 142 extending along the longitudinal direction of the fixed cross-beam 1211 does not exceed the connecting position of the connecting cross-beam 1212 and the fixed cross-beam 1211. The reinforcing plate 142 reinforces the connection between the fixed cross member 1211 and the frame upright 11, thereby enhancing the stability of the battery mounting direction and the load-bearing capacity of the mounting frame 121. Since the edges of the reinforcing plate 142 and the second segment 1412 do not exceed the fixing position of the connecting beam 1212 on the fixing beam 1211, the space on the mounting surface S is not affected to prevent the two ends of the battery from exceeding the mounting frame 121.

Referring to fig. 2, an embodiment of the utility model further provides a new energy vehicle, which includes a frame assembly 200 and a power battery (not shown), wherein the frame assembly 200 includes the above-mentioned general battery frame 100, and the power battery is mounted on the mounting surface S. The new energy vehicle mounted with the frame assembly 200 including the universal battery frame 100 has high adaptability to the battery size.

Further, there are two power batteries, the frame assembly 200 includes two sets of symmetrically disposed universal battery frames 100 and two frame connecting beams 21 for connecting the two sets of universal battery frames 100, each frame connecting beam 21 is respectively connected between two opposite frame uprights 11 of the two sets of universal battery frames 100, and the two power batteries are respectively disposed on the mounting surface S of the two sets of universal battery frames 100. It should be understood that the number of the power batteries is not limited to two, and a plurality of power batteries may be placed on the same mounting surface S, and the universal battery frame 100 included in the frame assembly 200 may be changed according to the size and number of the power batteries, and is connected to each universal battery frame 100, and is not limited in particular.

Furthermore, the frame assembly 200 further includes four connecting brackets 22, each connecting bracket 22 is respectively disposed at a connection position of one frame connecting beam 21 and one frame upright 11, and two ends of the connecting bracket 22 are respectively connected with the frame connecting beam 21 and the frame upright 11. The connection bracket 22 reinforces the connection of the frame connection beam 21 and the frame post 11, that is, the connection between the general-purpose battery frames 100.

Specifically, the cross section of the connecting bracket 22 is "U" shaped, and the opening faces away from the frame connecting beam 21, and the bottom far from the opening is connected to the frame connecting beam 21. The side perpendicular to the base is formed with two connecting webs corresponding to the first edge 112 and the second edge 114 of the frame upright 11 in the shape of a "zigzag", by means of which the connecting bracket 22 is connected to the frame upright 11. In this way, the connecting bracket 22 can be better adapted to the "inverted" frame upright 11.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
