Description
Technical Field
The invention relates to the field of battery replacement equipment, in particular to a quick-change bracket assembly and an electric automobile.
Background
The conventional battery pack mounting mode of the electric automobile is generally divided into a fixed mode and a replaceable mode.
The fixed battery pack is generally fixed on an automobile, and the automobile is directly used as a charging object during charging. When the fixed battery pack is connected to a vehicle body, the fixed battery pack is usually positioned by a pin and fixed by a bolt. The positioning and fixing method has good fixing effect, and can basically ensure the fixation of the three directions of X \ Y \ Z (X is in the horizontal plane and points to the direction of the automobile head, Y is in the horizontal plane and is vertical to the direction of X, and Z is in the height direction vertical to the horizontal plane). However, the battery pack is clumsy in replacement, the battery pack is inconvenient to flexibly disassemble, and meanwhile, the probability of bolt failure is increased due to repeated disassembly of the bolt, so that certain risks exist.
The replaceable battery pack is generally movably mounted, and the battery pack can be taken down at any time and replaced by a new battery pack. When the existing replaceable battery pack is connected with a vehicle body, a locking mechanism is usually used between the battery pack and the vehicle body, the locking mechanism generally comprises a lock shaft and a lock seat, the lock shaft is generally arranged on the side of the battery pack, the lock seat is arranged on the side of the vehicle body, and a slide way is arranged in the lock seat. The battery pack is generally mounted from the bottom of the vehicle body. The lock shaft enters the slide way of the lock seat from the lower part along with the battery pack, and then the battery pack moves in place along the X direction, so that the battery pack is installed. The battery pack mounting method is usually only used for floating positioning of the battery pack, and the battery pack is not fixed after floating positioning, namely the lock shaft can move in X \ Y \ Z directions relative to the slide way. Thus, during the running of the vehicle, the battery pack usually generates complex movement in the three directions of X \ Y \ Z, so that the failure rate of the battery pack is high, and the reason of the failure is difficult to judge after the battery pack fails. In addition, due to the complex movement of the battery pack, when the stress analysis is performed on the battery pack, the related stress analysis is also complex.
In summary, the fixed battery pack in the conventional electric vehicle is inconvenient to detach, and the replaceable battery pack cannot be fixed in X, Y or Z direction, so that the battery pack is prone to failure.

Preferably, when the double pendulum pin 42 is located at the positioning point, the center line of the double pendulum pin 42 is coplanar with the center lines of the two fixed shafts 412. In the scheme, by adopting the structure, the center line of the double swing pin 42 and the center lines of the two fixed shafts 412 are designed to be coplanar, when the double swing pin 42 is located at the positioning point, the distance between the double swing pin 42 and the two fixed shafts 412 is minimum, so that the two swing bodies 411 clamp the double swing pin 42 more tightly, the axial stress of the double swing pin 42 at the moment is maximum, the double swing pin 42 is difficult to leave the positioning point, and the stability of the double swing pin 42 is improved.
Similar to the slide positioning mechanism 30, the double pendulum positioning mechanism 40 may also be provided with a buffer part, at least a part of which is located in the slide 311, and the buffer part abuts against the wall surface of the double pendulum pin 42 when the double pendulum pin 42 is at the positioning point. In the embodiment, the buffer part is used for absorbing the kinetic energy of part of the double swing pins 42 when the double swing pins 42 are converted to the positioning state, so that the impact of the double swing pins 42 on the double swing seats 41 is reduced, the noise when the double swing pins 42 are positioned is reduced, and the stability when the double swing pins 42 are in the positioning state is improved.
Specifically, the present embodiment uses the cushioning portion as the elastic pad 50. In the embodiment, the elastic pad 50 is used as the buffer part, so that the cost of the buffer part is reduced, and the buffering effect of the buffer part is improved. In other embodiments, the buffer part can also be designed in other forms.
Example 2
This embodiment is an electric vehicle that includes a battery pack assembly 60 and a quick-change cradle assembly 10 as in embodiment 1. Fig. 16 is a battery pack assembly 60 in the present embodiment. The present embodiment utilizes the quick-change bracket assembly 10, so that the battery pack 61 of the electric vehicle is fixed in the driving direction of the electric vehicle, in the vertical direction and in the axial direction of the slide pin 32.
