[0043] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here, for example, can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0044] As mentioned in the background technology, as the waistline of the rear door is elongated, the lateral stiffness of the door is reduced, resulting in a loose seal between the water cut on the inner and outer panels of the door and the movable glass, and the inner and outer reinforcement plates of the waistline are easily deformed, producing abnormal noises, etc., affecting the car-using experience. At present, the stiffness of the inner and outer reinforcement plates of the waistline is improved by either increasing the material thickness or using high-strength materials. This method results in a large increase in cost and weight, but the stiffness improvement is not obvious. Or more one-piece reinforced connection structures are designed on the outer reinforcement plate of the waistline or the inner reinforcement plate of the waistline, making the structure more complex and changeable. This method increases the unit manufacturing cost of the inner and outer reinforcement plates of the waistline, and urgently needs to be optimized and solved.
[0045] In view of the above problems existing in the prior art, the utility model provides a rear door waistline reinforcement connection assembly, a rear door and a vehicle. The rear door waistline reinforcement connection assembly provided by the utility model includes a waistline outer reinforcement plate, a waistline inner reinforcement plate and a connection bracket. The waistline outer reinforcement plate is arranged on the waistline inner reinforcement plate, and the connection bracket is arranged between the waistline outer reinforcement plate and the waistline inner reinforcement plate, and is respectively connected to the waistline outer reinforcement plate and the waistline inner reinforcement plate, so as to increase the connection strength between the waistline outer reinforcement plate and the waistline inner reinforcement plate at the rear side of the movable glass. An installation cavity is left between the connection bracket and the front end of the waistline outer reinforcement plate and the waistline inner reinforcement plate for the lifting and moving of the movable glass. The side of the waistline outer reinforcement plate facing away from the connecting bracket is connected to the rear door outer panel, and the side of the waistline inner reinforcement plate facing away from the connecting bracket is connected to the rear door inner panel, so as to form the overall rear door of the vehicle, strengthen the waistline of the rear door outer panel and the rear door inner panel, and connect and strengthen the waistline outer reinforcement plate and the waistline inner reinforcement plate through the connecting bracket. This can significantly improve the strength of the rear door of the vehicle with a long waistline while reducing the cost and weight increase, thereby improving the car experience.
[0046] Hereinafter, exemplary application scenarios of the embodiments of the present utility model are introduced.
[0047] The rear door waistline reinforcement connection assembly provided by the utility model can be applied to passenger cars with fuel engines, and the so-called passenger cars generally include some light vehicles such as sedans, multi-purpose vehicles MPV (Multiple purpose vehicle), off-road vehicles SUV (Sportutility vehicle), etc. Specifically, the rear door waistline reinforcement connection assembly provided by the utility model can be applied to the rear door of the above-mentioned models. In this way, only by adding a connecting bracket to strengthen the connection between the waistline outer reinforcement plate and the waistline inner reinforcement plate at the rear side of the movable glass, the strength of the rear door of the long waistline can be significantly improved under the premise of less cost and weight increase, thereby improving the car experience.
[0048] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0049] Reference Figure 1-Figure 4 As shown, the rear door waistline reinforcement connection assembly provided in this embodiment includes a waistline outer reinforcement plate 100 , a waistline inner reinforcement plate 200 and a connection bracket 300 , and the waistline outer reinforcement plate 100 is arranged on the waistline inner reinforcement plate 200 .
[0050] The connecting bracket 300 is located between the waistline outer reinforcing plate 100 and the waistline inner reinforcing plate 200, and is connected to the waistline outer reinforcing plate 100 and the waistline inner reinforcing plate 200 respectively. An installation cavity 110 for raising and lowering the movable glass 600 is reserved between the connecting bracket 300 and the front end of the waistline outer reinforcing plate 100 and the waistline inner reinforcing plate 200.
[0051] The side of the waistline outer reinforcement plate 100 away from the connection bracket 300 is used to connect with the rear door outer panel 400 , and the side of the waistline inner reinforcement plate 200 away from the connection bracket 300 is used to connect with the rear door inner panel 500 .
[0052] In this embodiment, Figure 1 As shown, the waistline outer reinforcement plate 100 extends along the front-rear direction of the vehicle body, that is, extends along the length direction of the vehicle body, and has a reinforcement structure thereon for reinforcing the outer side of the door waistline.
[0053] The waistline inner reinforcement plate 200 also extends in the front-to-back direction of the vehicle body. The waistline inner reinforcement plate 200 can be integrally formed with the window frame, and it reinforces the inner side of the door waistline and the periphery of the door window. The front and rear ends of the waistline outer reinforcement plate 100 are fixedly connected to the front and rear ends of the waistline inner reinforcement plate 200, such as welding, bonding, screwing, clamping, etc., so that a cavity is left between the two, at least for installing a lifting glass, etc.
[0054] The connecting bracket 300 is located between the front end and the rear end of the waistline outer reinforcement plate 100, specifically close to the rear side of the lifting glass, so as not to interfere with the movement of the lifting glass. The two sides of the connecting bracket 300 are respectively connected to the waistline outer reinforcement plate 100 and the waistline inner reinforcement plate 200, such as welding, bonding, screwing, clamping, etc. The connecting bracket 300 can be a plate-shaped, block-shaped, special-shaped component, etc., which is convenient for manufacturing and installation.
[0055] The side of the waistline outer reinforcement plate 100 that faces away from the connecting bracket 300 is used to connect to the rear door outer panel 400, and the side of the waistline inner reinforcement plate 200 that faces away from the connecting bracket 300 is used to connect to the rear door inner panel 500 to form the entire rear door, thereby improving the waistline strength corresponding to the boundary between the movable glass and the fixed glass (or fixed trim panel) of the rear door.
[0056] It can be understood that, compared with the prior art where the thickness of the material is increased, high-strength materials are used, or strengthening structures are designed on the outer and inner reinforcement plates of the waistline, the application of the rear door waistline strengthening connection assembly in this embodiment can strengthen the connection between the outer waistline reinforcement plate and the inner waistline reinforcement plate through the connection bracket. It can significantly improve the strength of the rear door of a vehicle with a long waistline with less increase in cost and weight, thus improving the vehicle use experience.
[0057] Therefore, the rear door waistline strengthening connection assembly provided in this embodiment includes an outer waistline reinforcement plate 100, an inner waistline reinforcement plate 200, and a connection bracket 300. By arranging the outer waistline reinforcement plate 100 on the inner waistline reinforcement plate 200 and setting the connection bracket 300 between the outer waistline reinforcement plate 100 and the inner waistline reinforcement plate 200 and connecting them to the outer waistline reinforcement plate 100 and the inner waistline reinforcement plate 200 respectively, the connection strength between the outer waistline reinforcement plate 100 and the inner waistline reinforcement plate 200 at the rear side of the movable glass 600 is increased. An installation cavity 110 is left between the front end of the connection bracket 300 and the outer waistline reinforcement plate 100 and the inner waistline reinforcement plate 200 for the lifting movement of the movable glass 600. The side of the outer waistline reinforcement plate 100 facing away from the connection bracket 300 is connected to the rear door outer panel 400, and the side of the inner waistline reinforcement plate 200 facing away from the connection bracket 300 is connected to the rear door inner panel 500, thereby forming the overall rear door, strengthening the waistline of the rear door outer panel 400 and the rear door inner panel 500. By strengthening the connection between the outer waistline reinforcement plate 100 and the inner waistline reinforcement plate 200 through the connection bracket 300, the strength of the rear door of a vehicle with a long waistline can be significantly improved with less increase in cost and weight, thus improving the vehicle use experience.
[0058] In a possible design, as Figure 3 shown, in this embodiment, the connection bracket 300 includes a bracket body 310 and two support portions 320, and the two support portions 320 are relatively connected to both ends of the bracket body 310. The bracket body 310 is connected to the inner waistline reinforcement plate 200, and the end of the support portion 320 facing away from the bracket body 310 is connected to the outer waistline reinforcement plate 100. Alternatively, the bracket body 310 is connected to the outer waistline reinforcement plate 100, and the end of the support portion 320 facing away from the bracket body 310 is connected to the inner waistline reinforcement plate 200.
[0059] In this way, the bracket body 310 and the two support portions 320 form an approximate "冂" - shaped structure, meeting the requirements of the installation distance between the outer waistline reinforcement plate 100 and the inner waistline reinforcement plate 200, and at the same time playing a role in weight reduction. The bracket body 310 and the two support portions 320 can both be plate - like structures.
[0060] In one example, as Figure 2As shown, it is connected to the inner waistline reinforcement plate 200 through the bracket body 310, such as by welding, bonding, screwing, clamping, etc., and is connected to the outer waistline reinforcement plate 100 through two support parts 320, such as by welding, bonding, screwing, clamping, etc., to form a stable support, thereby strengthening the area between the outer waistline reinforcement plate 100 and the inner waistline reinforcement plate 200.
[0061] In another example, as Figure 4 shown, it is connected to the outer waistline reinforcement plate 100 through the bracket body 310, such as by welding, bonding, screwing, clamping, etc., and is connected to the inner waistline reinforcement plate 200 through two support parts 320, such as by welding, bonding, screwing, clamping, etc., which can also form a stable support, thereby strengthening the area between the outer waistline reinforcement plate 100 and the inner waistline reinforcement plate 200.
[0062] Furthermore, as Figure 3 shown, in this embodiment, the connecting bracket 300 further includes two flanges 330, and the two flanges 330 are correspondingly connected to the two support parts 320. For example, the flange 330 is located at one end of the support part 320 facing away from the bracket body 310, and the flange 330 is turned outwards in a direction away from the other one, and the flange 330 is connected to the outer waistline reinforcement plate 100 or the inner waistline reinforcement plate 200.
[0063] In this way, the bracket body 310, the two support parts 320 and the two flanges 330 form an approximate "U" - shaped structure, and the two flanges 330 can also be plate - shaped structures. One side of the connecting bracket 300 forms a surface contact with the outer waistline reinforcement plate 100 or the inner waistline reinforcement plate 200 through the bracket body 310, and the other side of the connecting bracket 300 forms a surface contact with the inner waistline reinforcement plate 200 or the outer waistline reinforcement plate 100 through the two flanges 330, further improving the connection stability.
[0064] To ensure the stability and rapidity of the connection of the flange 330, in this embodiment, the flange 330 is connected to the outer waistline reinforcement plate 100 or the inner waistline reinforcement plate 200 by welding. For example, spot welding, etc., can be realized by a manipulator, which is convenient for mass production, installation, etc.
[0065] To facilitate the mass production of the connecting bracket 300, as Figure 3 shown, in this embodiment, the bracket body 310, the two support parts 320 and the two flanges 330 are integrally formed. Exemplarily, the connecting bracket 300 can be an aluminum part, an aluminum alloy part, a steel part, etc., and the bracket body 310, the two support parts 320 and the two flanges 330 can be integrally formed by bending, stamping, casting, etc., so as to facilitate mass production and the product has good consistency.
[0066] In order to facilitate installation and fixation of the bracket body 310 , in this embodiment, the bracket body 310 is connected to the waistline outer reinforcement plate 100 or the waistline inner reinforcement plate 200 by at least one of clamping and bonding.
[0067] In one example, a buckle is provided on the side of the bracket body 310 away from the support portion 320, and a matching buckle is provided on the connection surface of the waistline outer reinforcement plate 100 or the waistline inner reinforcement plate 200 corresponding to the bracket body 310, and the buckle and the buckle are used to quickly connect and fix. In another example, a buckle is provided on the side of the bracket body 310 away from the support portion 320, and a matching buckle is provided on the connection surface of the waistline outer reinforcement plate 100 or the waistline inner reinforcement plate 200 corresponding to the bracket body 310, so that the buckle and the buckle can also be used to quickly connect and fix.
[0068] Of course, the bracket body 310 may also be coated with expansion glue on the side away from the support portion 320, and the bracket body 310 and the waistline outer reinforcement plate 100 or the waistline inner reinforcement plate 200 may be bonded by the expansion glue. In addition, in order to further enhance the stability of the connection, the bracket body 310 and the waistline outer reinforcement plate 100 or the waistline inner reinforcement plate 200 are connected by clamping and also bonded by glue.
