[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-4 , the utility model provides a technical solution:

[0021] Example 1

[0022] A low wind resistance car body connection device includes connecting parts 1, and there are eight groups of connecting parts 1. Aluminum alloy brackets 2 are connected between the connecting parts 1, and the two are connected by rivets. The connecting parts 1 are used to connect the aluminum alloy brackets 2 together. There are eight groups of aluminum alloy brackets 2. The eight groups of connecting parts 1 and aluminum alloy brackets 2 are used to support the car body frame.

[0023] The connector 1 includes a resistance reducing groove 11. The setting of the resistance reducing groove 11 can realize that the airflow directly passes through the resistance reducing groove 11 during the driving of the vehicle body, and avoids direct contact with the vehicle body, thereby reducing the wind resistance. The resistance reducing groove 11 is provided with a first wiring hole 12, the connector 1 is provided with a position light groove 13, and the position light groove 13 is provided with a mounting hole 14. The connector 1 is integrally connected with a connecting block 15, and the connector 1 is used to connect the aluminum alloy brackets 2 to each other.

[0024] It is worth noting that the connecting member 1 is integrally formed as a whole. Moreover, the surface of the connecting member 1 is arc-shaped, which can reduce wind resistance.
