DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on another element or indirectly on another element. It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0026] Please also read Figures 1 to 4Now, the vehicle body structure provided by the utility model is described. The vehicle body structure includes a side outer panel 10, a door opening sealing strip 20 and a door inner panel 30; the side outer panel 10 includes a first plate body 11 and a second plate body 12, wherein the first plate body 11 surrounds the door opening, and a cushioning layer 111 is provided on the surface of the first plate body 11 facing the outer side of the vehicle body; the second plate body 12 is arranged at an angle with the first plate body 11, and a drainage groove 121 is formed between the second plate body 12 and the cushioning layer 111; the door opening sealing strip 20 is arranged on the first plate body 11; the door inner panel 30 has a boss 31 protruding toward the inside of the vehicle body, and the boss 31 abuts against the door opening sealing strip 20.

[0027] It should be noted that a cushioning layer 111 is provided on part of the surface of the first plate body 11 to form a locally raised structure. The cushioning layer 111 can specifically be a carbon fiber layer bonded to the first plate body 11 with a raised height of not less than three millimeters. Of course, it can also be other material layers, such as a pad welded or pasted on the first plate body 11, or the first plate body 11 is directly formed by folding the edge of the first plate body 11; here, the first plate body 11 forms a door opening that cooperates with the inner panel 30 of the vehicle door, and the cushioning layer 111 can be extended from the boundary of the door opening toward the second plate body 12. Since the second plate body 12 is arranged at an angle to the first plate body 11, and the cushioning layer 111 is higher than the surface of the first plate body 11, a drainage groove 121 can be formed between the side wall of the cushioning layer 111 away from the boundary of the door opening and the second plate body 12, which can quickly discharge the water entering the door gap.

[0028] Furthermore, in the present embodiment, the door opening sealing strip 20 can specifically be a foam sealing strip that is the same as a conventional seal, and is connected to the first plate body 11 by a clip-on method. Since a cushioning layer 111 is added to the first plate body 11 compared to the conventional structure, the overall thickness of the first plate body 11 is increased, thereby improving the clip-on tightness between the door opening sealing strip 20 and the first plate body 11. This can further prevent water from penetrating along the first plate body 11 toward the stop edge on the basis of water blocking by the water blocking platform, thereby improving the waterproof sealing effect and improving the connection stability of the door opening sealing strip 20.

[0029] In this embodiment, the gap between the boss 31 and the first plate body 11 is smaller than the thickness of the door opening sealing strip 20. That is to say, when the door is closed, the door opening sealing strip 20 adaptively deforms based on the extrusion effect of the boss 31, thereby ensuring the contact sealing between the door opening sealing strip 20 and the table surface of the boss 31.

[0030] Compared with the prior art, the vehicle body structure provided in the present embodiment forms a seal between the side outer panel 10 and the door inner panel 30 by cooperating and squeezing the door opening sealing strip 20 through the first plate body 11 and the boss 31. On this basis, a drainage groove 121 is formed between the raised cushioning layer 111 on the surface of the first plate body 11 and the second plate body 12, which can not only block the water flow from penetrating into the door opening sealing strip 20 along the surface of the first plate body 11, but also enable the water flow entering the door gap to be quickly discharged through the drainage groove 121, thereby avoiding the problem of water flow remaining in the door gap for a long time in car washing or rainy environments, improving the cooperation and sealing between the side outer panel 10 and the door inner panel 30, avoiding water seepage and leakage into the vehicle, and helping to improve the vehicle use experience.

[0031] In some embodiments, see Figure 2 and Figure 3 The door opening sealing strip 20 is provided with a card slot 21, and the first plate body 11 extends into the card slot 21 and is engaged with the card slot 21. The door opening sealing strip 20 is engaged with the first plate body 11 by providing the card slot 21, which is convenient for disassembly, assembly and replacement, and the cushion layer 111 that extends into the card slot 21 together with the first plate body 11 can be used to improve the tightness of the engagement, thereby improving the sealing and reliability of the connection between the door opening sealing strip 20 and the first plate body 11.

[0032] Specifically, see Figure 3 and Figure 4 In this embodiment, the door opening sealing strip 20 is provided with a clamping rib 22, which is located at the mouth of the clamping groove 21, and the side wall of the cushion layer 111 facing the second plate body 12 is clamped with the clamping rib 22. The clamping rib 22 extends into the drainage groove 121 and forms a clamping connection with the groove wall of the drainage groove 121 (that is, the side wall of the cushion layer 111 facing the second plate body 12), thereby improving the connection reliability between the door opening sealing strip 20 and the first plate body 11 and preventing the door opening sealing strip 20 from falling off. In addition, the clamping rib 22 can also block the matching gap between the groove wall of the clamping groove 21 and the surface of the cushion layer 111, thereby further improving the waterproof sealing effect.

[0033] In order to further improve the connection stability between the door opening sealing strip 20 and the first plate body 11 and prevent the door opening sealing strip 20 from slipping off the first plate body 11, as shown in FIG. Figure 3As shown, a flexible tooth row 211 is provided on one side of the slot 21, and the flexible tooth row 211 abuts against the surface of the cushion layer 111; a support rib 212 is provided on the other side of the slot 21, and the support rib 212 abuts against the plate surface of the first plate body 11 facing the interior of the vehicle body. It should be understood that the clamping method between the slot 21 and the first plate body 11 is an interference fit, that is, the slot width of the slot 21 is less than the overall thickness of the first plate body 11 and the cushion layer 111. In this case, when the first plate body 11 and the cushion layer 111 are extended into the slot 21 together, each tooth of the flexible tooth row 211 can be deformed and collapsed into the gap between the teeth, thereby increasing the extrusion force and contact area between the flexible tooth row 211 and the surface of the cushion layer 111, thereby increasing the static friction between the two, and improving the connection reliability of the door opening sealing strip 20.

[0034] It should be noted that please combine Figure 1 and Figure 2 It is understood that in this embodiment, the door opening sealing strip 20 has a foaming cavity 23, the cavity wall of the foaming cavity 23 is in contact with the boss 31; an elastic clip 24 is provided inside the door opening sealing strip 20, and the elastic clip 24 is arranged around the clamping groove 21. The foaming cavity 23 can be deformed under the extrusion of the boss 31 to achieve a close sealing effect with the boss 31, thereby avoiding water leakage between the door opening sealing strip 20 and the boss 31; by arranging the U-shaped elastic clip 24 around the clamping groove 21 inside the door opening sealing strip 20, the clamping force of the clamping groove 21 on the first plate 11 can be improved, thereby improving the connection reliability of the door opening sealing strip 20.

[0035] For some examples, see Figure 1 and Figure 2 The above-mentioned vehicle body structure also includes a door outer panel 40 and a door glass 50. The door outer panel 40 is connected to the door inner panel 30, and a glass guide rail 60 is connected between the door outer panel 40 and the door inner panel 30. The glass guide rail 60 is embedded with a glass groove 61. The edge of the door glass 50 extends into the glass groove 61 and slides with the glass groove 61.

[0036] As a prior art, the door outer panel 40 and the door inner panel 30 are directly fitted and fixed as one body as one side of the door assembly boundary, while the side forming the door window is separated from each other to form a space for installing a glass guide rail 60. The two sides of the glass guide rail 60 are respectively connected to the door outer panel 40 and the door inner panel 30, which not only ensures the connection strength between the door inner panel 30 and the door outer panel 40, but also can realize the lifting and lowering guidance of the door glass 50 based on the glass guide rail 60. Of course, in order to ensure the sealing and quietness of the door glass 50, a glass felt groove 61 is also arranged inside the glass guide rail 60 in this embodiment. The specific structural form of the glass felt groove 61 is the same as the felt groove structure commonly used in existing vehicles, which will not be described in detail here.

[0037] For some possible implementations, see Figure 1 and Figure 2 A guide rail bracket 70 is connected between the door outer panel 40 and the door inner panel 30, and the guide rail bracket 70 is connected to the glass guide rail 60. By setting the guide rail bracket 70 to be connected to the door outer panel 40 and the door inner panel 30 respectively, on the one hand, the structural strength of the door outer panel 40 and the door inner panel 30 can be improved, and on the other hand, the guide rail bracket 70 can be used to support the glass guide rail 60, thereby improving the connection strength and rigidity of the glass guide rail 60, avoiding the problem of separation and detachment of the glass guide rail 60 from the door inner panel 30 and the door outer panel 40 due to frequent lifting and lowering of the door glass 50 and the vibration of the door switch, thereby improving the user experience.

[0038] Specifically, the optional structure of the guide rail bracket 70 in this embodiment is that the guide rail bracket 70 includes a first connecting portion 71 that is fitted and fixed to the door outer panel 40, a second connecting portion 72 that is fitted and fixed to the door inner panel 30, and a connecting support portion 73 that is respectively connected to the first connecting portion 71 and the second connecting portion 72; the glass guide rail 60 is fitted and fixed to the connecting support portion 73 and the second connecting portion 72.

[0039] Since a cavity is formed between the door outer panel 40 and the door inner panel 30 to accommodate the glass guide rail 60, the guide rail bracket 70 can be understood as a Z-shaped or U-shaped structure, and its three surfaces respectively form a first connecting portion 71, a second connecting portion 72 and a connecting support portion 73. On the one hand, the first connecting portion 71 fits with the door outer panel 40, and the second connecting portion 72 fits with the door inner panel 30 to increase the contact area and avoid stress concentration. At the same time, the connecting support portion 73 is used to form a supporting force between the door inner panel 30 and the door outer panel 40, thereby improving the overall structural strength of the door assembly and enhancing the anti-collision capability. On the other hand, the glass guide rail 60 is usually a U-shaped groove structure, so the connecting support portion 73 and the second connecting portion 72 can be respectively fitted and fixed to the two adjacent wall surfaces of the glass guide rail 60, thereby improving the connection strength of the glass guide rail 60 and avoiding the glass guide rail 60 from falling off or making abnormal noises during the lifting and lowering of the door glass 50 and the opening and closing of the door.

[0040] For example, in order to improve the overall collision resistance of the vehicle body, please refer to Figure 1 The above-mentioned vehicle body structure further includes a reinforcing beam 80, which is fixed to the side outer panel 10 facing the inner surface of the vehicle body. The reinforcing beam 80 can be a sheet metal part or a hollow structural beam formed by integral extrusion. Considering the vehicle body lightweight index, the hollow structural beam can be preferably used here, which can not only provide support for the side outer panel 10, thereby improving the strength of the side structure, but also the hollow structural beam itself has the characteristics of high strength and light weight, thereby improving the side collision safety performance under the vehicle body lightweight index.

[0041] Based on the same inventive concept, Figures 1 to 4It is understood that an embodiment of the present application also provides a vehicle, including the above-mentioned body structure.

[0042] Compared with the prior art, the vehicle provided by the utility model adopts the above-mentioned body structure, and can use the raised cushioning layer 111 on the surface of the first plate body 11 and the second plate body 12 to form a drainage groove 121, which can not only block the water flow from penetrating into the door opening sealing strip 20 along the surface of the first plate body 11, but also the water flow entering the door gap can be quickly discharged through the drainage groove 121, thereby avoiding the problem of water flow staying in the door gap for a long time in car washing or rainy environments, improving the matching sealing between the side outer panel 10 and the door inner panel 30, avoiding water seepage and leakage into the vehicle, and helping to improve the vehicle usage experience.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
