Description

Adjustable mounting assembly for the energy storage unit

Technical field

The present invention relates to the field of power exchange, and in particular to an adjustable mounting assembly of an energy storage unit.

Background technique

With the popularization of new energy vehicles, how to effectively provide fast and efficient energy replenishment for vehicles with insufficient energy has become a matter of great concern to car owners and major manufacturers. Taking electric vehicles as an example, current mainstream power supply solutions include charging solutions and battery replacement solutions. Among them, the battery replacement scheme is to replace the depleted battery of the electric vehicle directly with the full battery. Compared with the charging scheme, the battery replacement scheme is one of the main development directions of electric energy replenishment because it can be replaced in a short time and has no obvious influence on the service life of the power battery. The battery replacement scheme is generally completed in the charging station. Specifically, the charging and replacing platform is equipped with a charging stand and a power exchange platform, and a power-exchange trolley that carries a full/depletion battery between the charging stand and the power-changing platform, that is, the power-changing car completes the stop-and-go power change. The electric car on the platform is replaced by a battery. The electric vehicle can be positioned by the positioning mechanism, and the installation structure (such as the bolt) on the power battery is connected with the docking structure (such as the nut corresponding to the bolt) welded on the vehicle body, and the electric motor is completed. The action of installing a fully charged battery in a car.

However, the main problem with the above battery replacement scheme is that due to the large size of the power battery, the docking structure corresponding to the mounting structure on the power battery spans multiple positions of the vehicle body, and the cumulative error is large. Moreover, since the docking structure is fixed to the body of the automobile by welding, the above accumulated error cannot be reduced or eliminated, and there is also an error in the positioning accuracy of the changing trolley itself, which determines that the electric vehicle is in the power battery. When installing, it often takes several or even multiple positioning to complete the installation of the power battery. One of the ways to solve such problems is to improve the positioning accuracy of the electric-changing trolley. However, as a part of the power-changing system in the charging and replacing station, the electric-changing trolley has a complicated internal structure and many related systems involved, so it is improved. It is difficult and the cost of improvement is relatively high. It is precisely because of the above reasons that the replacement electric car cannot quickly and effectively replace the power battery for the electric vehicle, thereby reducing the service quality of the electric service.

That is, the second docking member 2 can be moved within the set range of the first docking member 1 to adjust the relative position between the power battery and the portion to be mounted, absorbing the accumulated error during the power exchange process, thereby making the power battery more Quickly connect to the part to be installed. It should be noted that the to-be-installed portion may be the body 4 of the electric vehicle (see FIG. 3A). The setting range may be a range that allows the second docking member 2 to move within the allowable error range of the power battery installation. That is, adjustable The first docking member 1 of the mounting assembly can be fixedly coupled to the vehicle body 4. After the first docking member 1 is fixed, the second docking member 2 can be moved within a set range with respect to the first docking member 1, and the movement The power battery can be fixed to the mounting position on the vehicle body 4 within an allowable error range by absorbing the cumulative error. It can be understood by those skilled in the art that the adjustable mounting component can also be disposed in a portion to be mounted equivalent to the body 4 of the electric vehicle, such as when the charging stand in the charging station is also fixed by a hanging type. The top of the bin structure to which a single power battery is attached to the charging stand can also be regarded as the portion to be mounted.

With reference to FIG. 1 , the second docking member 2 mainly includes a second docking base 21 and a docking structure 22 disposed on the second docking base 21 for the bolt to pass through.

Further, the dimension of the flange 12 in a direction perpendicular to the first butting base 11 may also be larger than the thickness of the second docking base 21 (refer to FIG. 3A). In this case, the second abutting member 2 can also generate a certain amount of displacement in the accommodating chamber in the axial direction.

It will be understood by those skilled in the art that although the first docking base 11 is substantially rectangular, this is not intended to limit the scope of the present invention, and may be adjusted, such as a square, without departing from the principles of the present invention. Or a circular first butt joint 11 and the like. Similarly, the setting position and setting mode of the pair of flanges 12 are not unique, and still follow the figure 2 As shown in the figure, the pair of flanges 12 may be respectively disposed on the left and right sides of the first butted bottom plate 11, or may be respectively disposed on the upper and lower sides and the left and right sides.
