Electric vehicle with quick change connector mounting bracket

Technical field

The present disclosure relates to the technical field of electric vehicles, and in particular to the field of quick-swap batteries for electric vehicles.

Background technique

At present, with the rapid development of new energy vehicles, the number of new energy vehicles has increased rapidly, and the number of models with battery quick-swap mode is also increasing year by year. At present, the mainstream quick-swap mode model in the market has the quick-swap connector directly installed on the vehicle body. The fixed point of the vehicle body is Projection welding studs or welding nuts cause the car body to have more features and a more complex structure. Once the model of the quick-change connector is changed, the fixed points of the corresponding installation parts on the car body must also be redesigned, which increases the cost of building a car.

Detailed ways

Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the present disclosure are included to facilitate understanding and should be considered to be exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the disclosure. Also, descriptions of well-known functions and constructions are omitted from the following description for clarity and conciseness.

This embodiment provides an electric vehicle with a quick-change connector mounting bracket. The electric vehicle includes but is not limited to pure electric vehicles and hybrid vehicles. The model of the electric vehicle can be a sedan, SUV, off-road vehicle, station wagon, MPV, pickup truck, etc.

The electric vehicle in this embodiment has the function of quick battery replacement, but it is not limited to only the function of quick battery replacement. It can also have a charging function.

The electric vehicle of this embodiment has a quick-change connector 100 connected to the power system of the body and a quick-change water pipe 200 connected to the cooling system of the body. The quick-change connector 100 is used to connect to the electrical interface of the battery to connect the body's The power system is electrically connected to the battery, so that the battery provides power to the power system of the vehicle body. The quick-change water pipe 200 is used to connect with the liquid cooling interface of the battery to connect the cooling system of the vehicle body with the cooling pipeline in the battery to utilize the cooling system of the vehicle body. The cooling pump of the cooling system realizes the cooling cycle in the battery.

In other embodiments, the electric vehicle may not include the quick-change water pipe 200 , that is, the vehicle body may not be provided with a cooling system for the battery, and the cooling cycle may be realized through a self-installed cooling circulation system in the battery.

In other embodiments, the quick-change connector 100 can also have the function of the quick-change water pipe 200 , that is, the electrical connection function and the liquid cooling connection function are integrated into the quick-change connector 100 to simultaneously achieve electrical connection with the battery and liquid cooling. connect.

As shown in Figure 1-5, the electric vehicle includes: a chassis 300 and a mounting bracket 500. The mounting bracket 500 is detachably mounted on the chassis 300. The mounting bracket 500 has a first mounting surface 511 opposite to the chassis 300. The first mounting surface 511 is used to install the quick-change connector 100 of the electric vehicle.

Since the quick-change connector 100 is installed through the mounting bracket 500 , the body sheet metal does not need to be provided with avoidance features or protrusions to adapt to the installation of the connector, which reduces features of the body sheet metal. Since the mounting bracket 500 is provided to install the quick-change connector 100, even if the model of the quick-change connector 100 is changed, only the mounting hole position of the quick-change connector 100 installation part of the mounting bracket 500 needs to be changed, and there is no need to change the body chassis. 300 installation points reduce design change costs. At the same time, the first mounting surface 511 is opposite to the chassis 300, which facilitates the installation with the interface of the quick-change connector 100 facing downwards. The mounting bracket 500 is particularly adapted to the battery installation of small electric vehicles.

In this embodiment, the mounting bracket 500 is installed on the chassis 300 through threaded fasteners such as bolts. In other embodiments, the mounting bracket 500 may be detachably mounted on the chassis 300 in a snap-fitting manner.

“Opposite” here means that the first mounting surface 511 is substantially parallel to the surface on the chassis 300 on which the mounting bracket 500 is fixed, so as to form an opposition.

The mounting bracket 500 also has a second mounting surface 531, and the second mounting surface 531 is used to install the quick-change water pipe 200 of the electric vehicle.

The second mounting surface 531 is also opposite to the chassis 300 of the electric vehicle.

Since both the quick-change connector 100 and the quick-change water pipe 200 are installed through the mounting bracket 500, the body sheet metal does not need to be provided with avoidance features or protrusions to adapt to the installation of the connector, which reduces the protruding features of the body sheet metal. Since the quick-change connector 100 and the quick-change water pipe 200 are fixed simultaneously through the mounting bracket 500, the number of mounting holes can be reduced. As shown in Figure 2, if the quick-change connector 100 and the quick-change water pipe 200 are installed respectively, 8 mounting holes are required. However, using the mounting bracket 500 of this embodiment, only 6 mounting holes are required (the first one in Figure 2 A fixing hole 513 for inserting bolts and other threaded fasteners).

Since the quick-change connector 100 and the quick-change water pipe 200 are installed through the installation bracket 500, the quick-change bracket, the quick-change connector 100, and the quick-change water pipe 200 can be separately assembled offline, that is, the quick-change connector 100 and the quick-change water pipe 200 are installed together. The bracket 500 is pre-installed, and then the mounting bracket 500 is installed on the vehicle chassis 300, thus optimizing the production line rhythm and saving production line work stations.
