[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] Referring to Figures 1 to 7 , a connection device of the present application is shown, which comprises integrally formed first and second brackets, wherein the first bracket is used for clamping the engaging flange 23 formed when the side wall outer plate 21 and the side wall extension plate 22 are engaged, and the second bracket is used for connecting with the side wall inner plate 24, thereby realizing firm connection between the side wall outer plate 21 assembly and the side wall inner plate 24, and effectively improving the strength of the side wall inner and outer plates.

[0032] Specifically, in the present embodiment, the first bracket comprises a clamping piece and a connecting plate 13, the clamping piece comprises a main plate part 11, the middle part of one side of the main plate part 11 in the width direction horizontally extends outwardly to form a protruding plate part 12, and the end of the protruding plate part 12 away from the main plate part 11 extends outwardly perpendicularly to form the connecting plate 13. The two ends of the side of the main plate part 11 provided with the protruding plate part 12 respectively bend outwardly to form bent plate parts 14, and the end of the bent plate part 14 away from the main plate part 11 horizontally extends in a direction away from the protruding plate part 12 to form a clamping plate part 15, the plate surface of the clamping plate part 15 is parallel to the plate surface of the main plate part 11, and the main plate part 11, the bent plate part 14 and the clamping plate part 15 jointly form a U-shaped clamping groove 101, which is adapted to the joint flange 23 formed when the side wall outer plate 21 and the side wall extension plate 22 are joined, so as to achieve firm clamping between the joint flange 23, and the arrangement of the U-shaped clamping groove 101 enables the connecting device 10 of the present application to have a clamping locking function, so that the entire connecting device 10 can be self-positioned and fixed during the assembly of the body side wall assembly, without the need for additional welding fixtures for auxiliary positioning, effectively improving the assembly efficiency and greatly reducing the operation complexity and development cost of the welding fixture.

[0033] Further, the clamping piece further comprises a first guide plate part 16 and a second guide plate part 17, the other side of the main plate part 11 in the width direction extends obliquely in a direction away from the clamping plate part 15 to form the first guide plate part 16, and the end of the clamping plate part 15 away from the bent plate part 14 extends obliquely in a direction away from the main plate part 11 to form the second guide plate part 17, and a widening guide hole is formed between the first guide plate part 16 and the second guide plate part 17, which is used to guide the joint flange 23 into the U-shaped clamping groove 101, so as to improve the operation convenience of the entire connecting device 10.

[0034] Further, the depth of the slot of the U-shaped clamping groove 101 is 12mm-16mm, the length of the slot is 22mm-26mm, and the width of the slot is 1mm-2mm. As a specific example, in the present embodiment, the depth of the slot of the U-shaped clamping groove 101 is 14mm, and the length of the slot is 24mm. Since the thickness of the side wall outer plate 21 in the present embodiment is 0.8mm and the thickness of the side wall extension plate 22 is 0.7mm, the width of the slot of the U-shaped clamping groove 101 is 1.5mm, so as to ensure that the clamping between the joint flange 23 formed when the side wall outer plate 21 and the side wall extension plate 22 are joined and the U-shaped clamping groove 101 is firm and secure.

[0035] Further, in the length direction of the main plate part 11, the end surface of one end of the bent plate part 14 is flush with the end surface of the main plate part 11, and a first gap 102 is provided between the end surface of the other end of the bent plate part 14 and the end surface of the protruding plate part 12, which makes the bending forming of the bent plate part 14 more convenient and effectively improves the manufacturing efficiency of the overall device.

[0036] Further, the bending plate part 14 is provided with a second notch 103, the second notch 103 is communicated with the U-shaped clamping slot 101, and the total length of the opening of the second notch 103 along the length direction of the main plate part 11 is less than the length of the slot opening of the U-shaped clamping slot 101. The provision of the second notch 103 not only reduces the mold pressure in the structure forming process of the U-shaped clamping slot 101 at both ends in the length direction of the clamping part, but also makes the whole structure easier to form, and can effectively prevent the springback after the structure of the U-shaped clamping slot 101 is formed, so as to better control the size of the slot opening width of the U-shaped clamping slot 101.

[0037] As an example, the second support includes a first side plate 18 and a second side plate 19 perpendicular to each other, the first side plate 18 is integrally connected with the connecting plate 13, and the second side plate 19 is arranged on the side of the first side plate 18 away from the connecting plate 13.

As a specific example, in the embodiment, the second side plate 19 is provided with two mounting holes 104, and the hole diameter of the mounting hole 104 is 7mm, so as to be used for welding M6 nuts. When the side wall inner plate 24 is positioned and spliced with the second side plate 19, the hard connection and fixation between the connecting device 10 and the side wall inner plate 24 can be realized through the screw connection of the bolt and the M6 nut.

[0039] Further, the second side plate 19 is further provided with at least one positioning hole 105, the positioning hole 105 is used for cooperating with a clamp to realize the accurate positioning and splicing of the side wall inner plate 24 on the second side plate 19. As a specific example, in the embodiment, the second side plate 19 is provided with one positioning hole 105, and the positioning hole 105 is located between the two mounting holes 104. It should be noted that the clamp is a clamp device known to those skilled in the art, which will not be described here.

[0040] The application also provides a vehicle, which comprises a side outer plate 21, a side extension plate 22, and at least one connecting device 10, the side outer plate 21 is provided with a first connecting flange, the side extension plate 22 is provided with a second connecting flange, when the side outer plate 21 is combined with the side extension plate 22, the first connecting flange and the second connecting flange are tightly combined to form a combined flange 23, and the combined flange 23 is used for clamping connection with a U-shaped clamping groove 101. Since the size of the integrated side outer plate in a light passenger vehicle is large and the rigidity is relatively weak, the side outer plate is prone to deformation and shaking during the welding and transfer process of the side assembly in the welding workshop, so that the gap between the inner plate and the outer plate cannot be controlled. Therefore, as a specific example, the front part, the middle part and the rear part of the integrated side outer plate of the vehicle body are respectively provided with one connecting device 10, so as to realize the hard connection between the entire side outer plate 21 and the side inner plate 24 skeleton assembly, effectively control the gap between the side inner plate and the side outer plate during the transfer process of the vehicle body side, and ensure that the shock-absorbing glue between the side inner plate and the side outer plate can play a good shock-absorbing connection role, thereby reducing the risk of abnormal sound between the side panels of the vehicle during driving.

[0041] Further, the second connecting flange is further provided with a positioning notch 201, and the positioning notch 201 is used for limiting the clamping position of the connecting device 10 on the combined flange 23.

[0042] Further, when the combined flange 23 is clamped into the U-shaped clamping groove 101 and stably clamped, the plate surface joint between the main plate part 11, the side outer plate 21 and the side extension plate 22 in the first notch 102 is fixedly connected by welding.

[0043] Further, the vehicle further comprises a side inner plate 24, the side inner plate 24 is provided with a plurality of mounting holes 104, the mounting holes 104 are matched with bolts, the bolts are sequentially threaded through the connecting holes 202 and the mounting holes 104 and are threadedly connected with nuts, so as to realize the fixed connection between the connecting device 10 and the side inner plate 24.

[0044] In actual application, the assembly process of the connecting device 10 on the vehicle body side can be as follows: Figures 3 to 5As shown in the figure, when the workshop operator assembles the connecting device 10 on the vehicle body side panel, first, the U-shaped card slot 101 on the first bracket is snapped onto the middle of the positioning notch 201 on the side panel extension plate 22, and then the first bracket is pressed down by hand so that the U-shaped card slot 101 can be firmly snapped onto the joint flange 23, realizing the fixation of the position of the first bracket on the joint flange 23. Next, solder joints are made between the three layers of plates where the main board part 11 on the first bracket, the outer side panel 21, and the side panel extension plate 22 overlap. More specifically, solder joints can be made at the joint of the three-layer plate surfaces between the main board part 11, the outer side panel 21, and the side panel extension plate 22 located within the first notch 102, thereby realizing the fixed connection between the first bracket and the end assembly of the outer side panel 21.

[0045] Finally, the inner side panel 24 is accurately aligned and spliced onto the outer side panel 21 and the second side panel 19 by using the cooperation between the fixture and the positioning hole 105 on the second side panel 19, so that the hole position of the connecting hole 202 on the inner side panel 24 is aligned with the M6 nut on the second side panel 19. Subsequently, a bolt is passed through the connecting hole 202 and screwed with the nut to realize the firm connection between the inner side panel 24 and the connecting device 10. By Figure 5 and Figure 7 comparison, it can be seen that after the connecting device 10 of the present application is assembled on the inner and outer panels of the vehicle body side panel, it can partition the cavity between the inner and outer panels of the side panel, separate the middle part of the original "mouth" - shaped cavity structure in Figure 7 , and finally form the "day" - shaped cavity structure in Figure 5 , effectively improving the stiffness and local mode of the side panel, enhancing the vehicle's safety collision performance, and reducing the risk of jitter and cracking during the long - term driving of users.

[0046] It should be noted that according to the statistical data of the gap and degumming state between the inner and outer panels of the side window frame area of multiple off - line white vehicle bodies in the prior art, it is found that the gap between the inner and outer panels of the side panel exceeds the tolerance and the degumming area mainly appears in the area above the side window frame in the middle of the side panel. Therefore, as Figure 6 shown, three connecting devices 10 are evenly spaced between the B - pillar and the D - pillar in the side window frame area of the side panel, thereby effectively ensuring the connection stability between the inner and outer panels of the side panel.

[0047] In summary, the beneficial effects of the connecting device of the present utility model are as follows: In practical applications, the connecting device of the present application can achieve a hard connection between the inner and outer panels of the side panel, effectively ensuring the connection stability between the inner and outer panels of the side panel, and thereby enhancing the strength and stiffness of the inner and outer panels of the side panel; at the same time, during the assembly process of the connecting device of the present application on the inner and outer panels of the side panel, self - positioning installation can be realized through the two U - shaped card slot structures on the first bracket, without the need for additional welding fixture assistance for positioning, greatly improving the assembly efficiency and having high applicability.
