[0027] In this embodiment, the outer side refers to the upper part of the car, the inner side refers to the lower part of the car, the front part refers to the end near the front of the car, and the rear part refers to the end near the parking space.

[0028] Example 1

[0029] This embodiment provides an A-pillar connector, such as Figures 1-2 As shown, a cast aluminum upper connector is used, including a connector body, which is used to connect between the A-column and the top edge beam.

[0030] The connector body includes a first connector part 1 and a second connector part 2. One end of the first connector part 1 serves as a top edge beam connection end for fixing to the end of the top edge beam, and the other end is integrally connected to one end of the second connector part. The other end of the second connector part serves as an A-pillar connection end for connecting and fixing to the A-pillar.

[0031] The included angle between the first joint 1 and the second joint 2 matches the tilt angle of the car's windshield, that is, matches the included angle between the car's windshield and the outer panel of the roof, so that the second joint 2 can be fixed to the side edge of the car's windshield, replacing the top edge beam to fix the windshield. This eliminates the need for the top edge beam to be bent to match the windshield, reducing the bending angle requirement for the top edge beam.

[0032] The outer edge of the second connector 2 is turned up toward the windshield to form the windshield adhesive part 3. The windshield adhesive part 3 is a plate-shaped structure with a windshield adhesive surface for fixing to the side edge of the windshield.

[0033] The outer edge of the first connector 1 is turned up toward the windshield to form the top cover fixing part 4. The top cover fixing part 4 is a plate-shaped structure with fixing holes for fixing to the side of the front end of the top cover outer plate.

[0034] The inner edge of the entire connector body is flanged to form the front door opening stop 5. This integrated design reduces the number of separate door opening stop components.

[0035] The top edge beam connecting end of the first connector 1 is provided with at least one first fixing hole 6. In this embodiment, the top edge beam connecting end of the first connector 1 is provided with two first fixing holes 6. The first connector 1 can be fixedly connected to the end of the top edge beam through the first fixing holes 6.

[0036] The A-pillar connection end of the second connector 2 is provided with at least one second fixing hole 7. In this embodiment, the A-pillar connection end of the second connector 2 is provided with three second fixing holes 7, and the second connector 2 can be fixedly connected to the top of the A-pillar through the second fixing holes 7.

[0037] In this embodiment, the first joint 1 is fixedly connected to the top edge beam by means of Hack rivets and structural adhesive through the first fixing hole 6, and the second joint 2 is fixedly connected to the top of the A-pillar by means of Hack rivets and structural adhesive through the second fixing hole 7.

[0038] By using this cold connection process instead of welding, the structural shear resistance is more than five times that of traditional spot welding. This improves the connection strength between the A-pillar joint and the top edge beam and A-pillar, thereby enhancing the safety of the vehicle body during a collision. Furthermore, it reduces structural thermal deformation caused by welding and improves the dimensional accuracy of the vehicle body frame.

[0039] To enable the A-pillar to be connected and fixed to the A-pillar joint and the top edge beam using the SPR process, the end of the windshield adhesive part 3 near the A-pillar connection end is provided with a notch 8 to allow space for fixing the A-pillar to the second joint part 2 using Hack rivets using the SPR process. Preferably, two notches 8 are provided. The cover plate fixing part 4 is provided with a recessed area 9 to allow space for fixing the top edge beam to the first joint part 1 using Hack rivets using the SPR process. Preferably, three recessed areas 9 are provided.

[0040] It is understandable that the first joint can also be fixed to the top edge beam by welding or threaded fasteners, and the second joint can also be fixed to the A-pillar by welding or threaded fasteners. Those skilled in the art can set it according to actual needs.

[0041] In this embodiment, a reinforcing plate 10 is provided on the side of the first joint portion 1 and the second joint portion 2 facing the direction of the car. The reinforcing plate 10 adopts a flanged reinforcing rib to increase the local structural strength of the joint on the entire A-pillar, thereby improving its impact resistance. It is understood that the reinforcing plate can also adopt a straight plate structure, which can be set according to actual needs by those skilled in the art.

[0042] Example 2

[0043] This embodiment provides an automotive frame body structure, including the A-pillar connector described in Embodiment 1, such as... Figure 3 As shown, the top edge beam connecting end of the first joint part 1 is fixedly connected to the top edge beam 11 through the first fixing hole, and the top edge beam connecting end of the first joint part 1 is fixedly connected to the top edge beam 11 by means of Hack rivets and structural adhesive.

[0044] The A-pillar connection end of the second connector 2 is connected to the top of the A-pillar 12 through the second fixing hole, and the A-pillar connection end of the second connector 2 is fixedly connected to the top of the A-pillar 12 by means of Hack rivets and structural adhesive.

[0045] Both the top edge beam 11 and the A-column 12 are made of extruded aluminum profiles and can be constructed using existing structures. Their specific structures will not be described in detail here. The top of the A-column 12 is provided with a fixing hole that matches the first fixing hole, and the end of the top edge beam 11 is provided with a fixing hole that matches the second fixing hole.

[0046] The other structural elements of the frame body can be the existing automotive frame body structure, and will not be described in detail here.

[0047] Example 3

[0048] This embodiment provides a car equipped with the car frame body structure described in Embodiment 2, such as... Figure 4As shown, the side edge of the windshield 13 of the car is fixed to the windshield adhesive part 3 through the windshield adhesive surface. The fixing method can adopt the existing fixing method of the windshield and the adhesive fixing surface, which will not be described in detail here. The front end of the car roof outer panel 14 is fixed to the roof fixing part 4 of the first joint part 1 through fixing holes and Hack rivets. It also includes a door opening stop plate 15. The door opening stop plate 15 is located below the door opening stop part 5 and is connected to the lower end of the door opening stop part 5. It is fixedly connected to the A-pillar 12 by MIG welding process.

[0049] Other structural features of the car can be achieved using existing technology and will not be described in detail here.

[0050] In this embodiment, the windshield is fixed by a connector on the A-pillar instead of the top side beam, and the connector forms a larger bending angle instead of the top side beam. Therefore, the top side beam does not need a large bending angle, and there are no requirements for bending the top side beam, which facilitates processing and manufacturing and meets the needs of various body styles, especially hardcore off-road bodies.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
