[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] Embodiment 1

[0033] This embodiment relates to a door window frame root reinforcement structure, which can improve the firmness of the connection between the main body 10 of the door inner panel 1 and the window frame 11; an exemplary structure thereof is as follows Figure 1 , Figure 2 and Figure 3 shown.

[0034] In general, the door window frame root reinforcement structure includes a reinforcement bracket 3 arranged in a cavity formed between a door inner panel 1 and a door outer panel. The door inner panel 1 includes a main body 10 and a window frame 11 connected to the main body 10 at its root; the reinforcement bracket 3 is arranged at the connection between the main body 10 and the window frame 11, and includes an upper section 300 overlapped on the window frame 11, and a lower section 301 overlapped on the main body 10, and the lower section 301 has an extension portion 304 extending toward the inside of the door inner panel 1.

[0035] It should be pointed out that based on the above-mentioned overall design concept, the technical solution of the utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. Among them, the reinforcing bracket 3 can be designed in a variety of different forms of specific structures to ensure that the upper section 300, the lower section 301 and the extension 304 can be arranged in principle to be connected with the window frame part 11, the main part 10, and the internal plate body of the main part 10 of the door inner panel 1. For the parts required for the implementation of the overall solution but not involved in the above-mentioned overall setting, reasonable and flexible designs can also be made with reference to the mature setting means in the field, the actual situation during implementation, etc. The specific implementation scheme described below in this embodiment is only a better one of the many schemes that can be formed by the above-mentioned various combinations and their changes. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many schemes that can be formed by the above-mentioned various specific forms of combination and its changes, as well as the specific implementation scheme of this embodiment, are all within the scope of protection of the utility model.

[0036] Based on the above design ideas, such as Figure 1 , Figure 2 Combined with Figure 3 As shown, the door window frame root reinforcement structure of this embodiment mainly includes a door inner panel 1, a glass guide rail 2, a reinforcement bracket 3, a reinforcement plate 4 and other components.

[0037] As for the material of the reinforcing bracket 3, a stamped steel plate is preferably used, and the thickness of the plate can be set to be about 1.2 mm; in this way, the weight of the reinforcing bracket 3 itself can be reduced while ensuring the structural performance of the reinforcing bracket 3.

[0038] In addition, a plurality of grooves 302, weight-reducing holes 303 and other structures may be provided on the reinforcing bracket 3, so as to improve the structural strength of the reinforcing bracket 3 and reduce the weight of the reinforcing bracket 3. Figure 3As shown, a long strip-shaped groove 302 extending downward from the upper section 300 to the lower section 301 is provided in the middle of the reinforcing bracket 3, and the groove 302 can increase the strength of the reinforcing bracket 3 and improve the anti-deformation ability of the reinforcing bracket 3. Based on the fact that the structural strength requirement of the lower section 301 is relatively low, a weight-reducing hole 303 is provided on the lower section 301 of this embodiment to achieve the purpose of weight reduction.

[0039] Based on the overall arrangement of the reinforcing bracket 3 described above, in this embodiment, the extension portion 304 is configured to be stepped relative to the lower section 301, so that a cavity is formed between the lower section 301 and the door inner panel 1. The lower section 301 and the extension portion 304 of the reinforcing bracket 3 are configured to be stepped, and the cross-sectional shape thereof is roughly "Z"-shaped. The edges of the lower section 301 and the extension portion 304 on both sides overlap the door inner panel 1, so that a cavity is formed between the door inner panel 1 and the lower section 301, which can improve the structural stability of the connection between the main body portion 10 and the window frame portion 11 and the buffering effect on the impact force.

[0040] Furthermore, since the extension portion 304 needs to be bent to form a step structure, it is preferred to form a plurality of reinforcing protrusions 305 at the bend of the extension portion 304. Providing the reinforcing protrusions 305 at the bend of the extension portion 304 can enhance the structural firmness of the bend.

[0041] like Figure 4 and Figure 5 As shown, the reinforcing structure of the door window frame root of this embodiment also includes a reinforcing plate 4 arranged at the top edge of the main part 10; the corner of the extension part 304 is provided with a lap plate 33 protruding toward the inside of the door inner panel 1, and the lap plate 33 is clamped between the reinforcing plate 4 and the door inner panel 1. The reinforcing plate 4 is arranged at the top edge of the main part 10 (i.e., the lower frame part of the window), which can improve the stability of the entire window frame structure. By reserving a gap of 1.2mm (the plate thickness of the reinforcing bracket 3) between the end of the reinforcing plate 4 and the main part 10, the lap plate 33 at the corner of the extension part 304 is clamped between the reinforcing plate 4 and the main part 10, and the reinforcing plate 4, the reinforcing bracket 3 and the door inner panel 1 can be fixedly connected by three-layer spot welding. As for the plate shape of the lap plate 33, of course, it should be set according to the shape of the main part 10 where it overlaps, so that the lap plate 33 fits tightly on the main part 10. The coordinated arrangement of the reinforcing plate 4 and the lap plate 33 can make the connection between the reinforcing bracket 3 and the door inner panel 1 more secure, and further enhance the structural firmness of the connection between the window frame portion 11 and the main body portion 10 .

[0042] In addition, the upper section 300 of this embodiment is formed with a rim 32 on the side facing the inside of the vehicle window, and the rim 32 wraps around the edge of the window frame 11. The rim 32 is arranged on the side of the upper section 300 to wrap the window frame 11, further increasing the contact area between the upper section 300 and the window frame 11, and effectively enhancing the connection firmness between the window frame 11 and the upper section 300. Figure 3 It can be seen that the edging 32 extends downward and is connected to the facade in the step structure of the extension portion 304. This greatly enhances the structural strength of the connection between the upper section 300 and the lower section 301, thereby further reducing the risk of cracking at the connection between the main body portion 10 and the window frame portion 11.

[0043] Based on the setting of the edging 32, in this embodiment, a glass rail 2 is also provided on the window frame portion 11, and the edging 32 is clamped between the glass rail 2 and the window frame portion 11, and a plurality of bosses 320 for abutting the glass rail 2 are formed on the edging 32. A plurality of bosses 320 are provided on the edging 32, and the contact area between the upper section 300 and the glass rail 2 can be reduced by using the bosses 320 to abut the glass rail 2. When each boss 320 is welded and fixedly connected to the glass rail 2 at multiple points, each boss 320 is easy to fit tightly on the glass rail 2, which can reduce the situation of poor welding and improve the efficiency of the welding operation; through welding, the upper section 300, the glass rail 2 and the window frame portion 11 can be firmly fixedly connected as a whole. As for the setting size of the edging 32, its height can be set at about 20 mm, and the bend on the edging 32 preferably adopts a rounded transition with a radius of about 8 mm.

[0044] like Figure 3 and Figure 4 , Figure 5As shown, relative to the side where the edge 32 and the extension 304 are provided, a side flange 31 is formed on the other side of the reinforcing bracket 3 (i.e., the side close to the edge of the door inner panel 1), and the side flange 31 is overlapped on the door inner panel 1. Preferably, the side flange 31 of this embodiment is provided with a plurality of spaced-apart sunken platforms 310, and the bottom of each sunken platform 310 is abutted and connected with the door inner panel 1. By providing the side flange 31, the side flange 31 is overlapped on the step structure formed at the edge of the door inner panel 1, so that the side flange 31 and the door inner panel 1 are conveniently welded and fixedly connected. When multiple sinkers 310 are provided on the side flange 31, the side flange 31 will be connected to the door inner panel 1 through the bottom of the sinkers 310, so that a certain gap will be reserved between other parts of the side flange 31 and the door inner panel 1 (it is preferred to set the depth of the sinkers 310 to about 2.7 mm, that is, the gap between the non-sinkers 310 parts of the side flange 31 and the door inner panel 1 is about 2.7 mm). This can avoid large-area contact between the side flange 31 and the door inner panel 1. When the sinkers 310 are spot-welded to the door inner panel 1, it can ensure that each sinker 310 is tightly attached to the door inner panel 1, thereby reducing the possibility of poor welding and improving the efficiency of the welding operation.

[0045] Based on the above arrangement, a lug 311 protruding toward the edge of the door inner panel 1 can also be formed on the sink 310; the side flange 31 can be welded to the door inner panel 1 using a plurality of lugs 311 distributed on each sink 310. By providing the protruding lugs 311 on the sink 310, it is more convenient to weld each lug 311 to the door inner panel 1, and it is beneficial to increase the overall structural strength of the window frame portion 11.

[0046] During the specific assembly, the reinforcing bracket 3 is firstly set on the door inner panel 1, and the lugs 311 on the outside of the reinforcing bracket 3 are attached to the edge of the door inner panel 1, and are fixedly connected by spot welding; the edging 32 of the upper section 300 forms a covering on the inner edge of the window frame part 11, and then the glass guide rail 2 is fixedly installed on the window frame part 11, so that the edging 32 is clamped between the glass guide rail 2 and the window frame part 11, and the window frame part 11, the edging 32 and the glass guide rail 2 are welded and fixedly connected. At this time, the lap plate 33 is set on the top edge of the main part 10, and then the reinforcing plate 4 is stacked on the top edge of the main part 10, and the lap plate 33 is clamped between the reinforcing plate 4 and the main part 10, and the three are also fixedly connected by three-layer spot welding. In this way, the structural firmness of the connection part between the main part 10 and the window frame part 11 of the door inner panel 1 will be greatly improved.

[0047] To sum up, in the door window frame root reinforcement structure of the present embodiment, the upper and lower sections of the reinforcement bracket 3 are respectively overlapped on the main part 10 and the window frame part 11 of the door inner panel 1, and the window frame part 11 is also provided with an extension part 304 extending toward the inner direction of the main part 10, thereby forming a good structural reinforcement effect on the root of the window frame part 11, which can effectively reduce the risk of cracking at the connection part of the main part 10 and the window frame part 11, and can improve the firmness of the connection part of the main part 10 and the window frame part 11 of the door inner panel 1.

[0048] Embodiment 2

[0049] This embodiment relates to a vehicle, the vehicle door of which adopts the door window frame root reinforcement structure provided in the first embodiment.

[0050] By setting the reinforcing bracket 3, the reinforcing bracket 3 uses the side flange 31, the edging 32 and the extension part 304 formed thereon to connect the glass guide rail 2, the door inner panel 1 and the reinforcing plate 4 into a whole, thereby effectively increasing the structural strength of the root part of the door window frame, thereby improving the impact resistance of the sheet metal d at the window frame, and reducing the risk of sheet metal cracking at the connection part of the main part 10 of the door inner panel 1 and the window frame part 11 during the use of the door.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
