The following describes in more detail embodiments of the present invention with reference to the schematic drawings. The advantages and features of the present invention will become more apparent from the following description. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
As shown in fig. 1-2, the invention provides a battery bracket of a new energy automobile, which comprises a fixing frame 1, a loading frame 2 and an elastic connecting mechanism. The fixing frame 1 is of a rectangular frame structure, and the fixing frame 1 is horizontally and fixedly connected to the bottom of a frame of the new energy automobile through bolts. The loading frame 2 is used for loading battery packs, the loading frame 2 is cubic and is arranged opposite to the fixed frame 1 up and down, and the loading frame 2 is locked with the fixed frame 1 through a locking mechanism when moving upwards and is connected with the bottom of the fixed frame 1, so that the loading frame 2 and the fixed frame 1 are in a relatively fixed state, and the battery packs are fixed between the loading frame 2 and the fixed frame 1.
The loading frame 2 is connected with the fixed frame 1 through an elastic connection mechanism, the elastic connection mechanism comprises two elastic connection modules which are respectively arranged on two sides of the fixed frame 1 and are oppositely arranged, one end of each elastic connection module is connected with the fixed frame 1, and the other end of each elastic connection module is connected with the movable frame. When the locking mechanism releases the locking of the loading frame 2, the elastic connecting mechanism enables the loading frame 2 to gradually move downwards relative to the fixed frame 1 and keep a horizontal state in the downward movement process.
Specifically, as shown in fig. 2, the elastic connection module includes a first connection rod 3 and a second connection rod 4, the first connection rod 3 and the second connection rod 4 are equal in length and are arranged in parallel, and two ends of the first connection rod 3 and two ends of the second connection rod 4 are respectively rotatably connected with the side wall of the fixed frame 1 and the side wall of the loading frame 2 to form a parallelogram structure. Springs 5 are connected between the first connecting rod 3 and the fixed frame 1 and between the second connecting rod 4 and the fixed frame 1. After the locking mechanism is unlocked to the loading frame 2, the loading frame 2 moves downwards, the first connecting rod 3 and the second connecting rod 4 rotate downwards, the spring 5 is stretched, the elasticity of the spring 5 to the first connecting rod 3 and the second connecting rod 4 is increased, the loading frame 2 cannot suddenly accelerate to move downwards, and the loading frame 2 can be kept stable when moving downwards. The spring constant of the spring 5 may be selected according to the weight of the battery pack and the carrier 2 and the maximum extension of the spring 5 when in use.
And, all run through on first connecting rod 3 and the second connecting rod 4 and seted up first spacing hole 6, be provided with on the lateral wall of loading frame 2 with first spacing hole 6 assorted first spacing groove 7, first connecting rod 3 and second connecting rod 4 can be through inserting the spacing bolt 8 locking for loading frame 2 of establishing in first spacing hole 6 and first spacing groove 7.

Specifically, as shown in fig. 7, the sliding mechanism 19 includes a mounting plate 20 and a plurality of rotating shafts 21 disposed on the mounting plate 20 at intervals along the extending direction of the mounting plate 20, the mounting plate 20 is U-shaped, two ends of the rotating shafts 21 are rotatably connected to the tops of the side vertical plates of the mounting plate 20, and the tops of the rotating shafts 21 are higher than the top surface of the mounting plate 20. The mounting plate 20 is fixedly attached to the inner bottom of the carrier 2 by screws. The outer side surface of the rotating shaft 21 can be wrapped with a silica gel layer to provide flexible support for the bottom of the battery pack.
Before the battery pack is disassembled, the automobile is lifted to a proper height by the automobile lifting machine, then the bottom of the loading frame 2 is supported by the lifting machine with universal wheels at the bottom, then the locking bolt 12 is taken out, the height of the lifting machine is slowly reduced after the locking of the locking mechanism on the loading frame 2 is released, and the loading frame 2 can descend along with the descending of the lifting machine under the action of the gravity of the battery pack and the loading frame 2.
In the process that descends, load carrier 2 breaks away from the contact with mount 1, and the elasticity that makes progress that elastic connection mechanism provided increases gradually, guarantees that the atress of load carrier 2 whereabouts in-process is stable, also can avoid when the battery package weight surpasss the bearing weight of lifting machine, and load carrier 2 can not suddenly accelerate the whereabouts to can not cause danger.
When the loading frame 2 moves to the lowest point, the first connecting rod 3 and the second connecting rod 4 are kept in a relatively fixed state with the loading frame 2 after the limiting bolt 8 is inserted into the first limiting hole 6 and the first limiting groove 7. After the side plate 17 is taken down, the battery pack is directly pulled out from the loading frame 2 to the detection platform, so that the battery pack is more convenient, quicker and safer to replace, and the installation time of operators is shortened.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
