Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.
[0023] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0024] like Figure 1 The reinforcement 1 shown includes a reinforcement body, on which a first plate portion 101, an outwardly extending first extension portion 105, and an outwardly extending second extension portion 109 are provided. The first plate portion 101 is used to fixally connect with the tail wing elevator mounting portion on the inner panel 2 of the tail door to reinforce the tail wing elevator mounting portion. The end of the first extension portion 105 is provided with a second plate portion 106 for fixingly connecting with the upper plate 3 of the outer panel of the tail door. The end of the second extension portion 109 is provided with a third plate portion 110 for fixingly connecting with the lower plate 4 of the outer panel of the tail door.
[0025] By adopting the above technical solution, firstly, the first plate 101 is fixedly connected to the tail wing elevator mounting part, which can directly strengthen the tail wing elevator mounting part. Secondly, the second plate 106 is fixedly connected to the upper plate 3 of the outer tailgate panel, and the third plate 110 is fixedly connected to the lower plate 4 of the outer tailgate panel. The reinforcing member 1 forms a connection between the inner tailgate panel 2 and the outer tailgate panel, which can improve the strength of the tailgate cavity. Thirdly, by forming a cage-like reinforcing structure through the connection between the inner tailgate panel 2 and the outer tailgate panel, the strengthening effect on the tail wing elevator mounting part can be improved.
[0026] In some embodiments, a mounting nut 102 for mounting the tail wing lifter is fixedly connected to the first plate portion 101. By adopting the above technical solution, integrating the mounting nut 102 onto the reinforcing member 1 can reduce the number of mounting brackets, resulting in fewer parts, optimizing space layout, reducing part development costs, and reducing the requirements for welding fixtures.
[0027] In some embodiments, the reinforcing member body is provided with two mutually spaced first plate portions 101, and a rib 115 is formed by an upward protrusion on the portion of the reinforcing member body located between the two first plate portions 101. By adopting the above technical solution, the provision of two first plate portions 101 increases the connection points between the reinforcing member body and the inner panel 2 of the tailgate, which helps to ensure the stability of the connection between the reinforcing member body and the inner panel 2 of the tailgate, and can better ensure the installation accuracy of the reinforcing member 1. Each of the two first plate portions 101 can be fixedly connected to a mounting nut 102, and the two mounting nuts 102 can achieve a stable installation of the tail wing lifter. The rib 115 can improve the structural strength of the reinforcing member body, and the groove formed by the upwardly protruding rib 115 can separate the two first plate portions 101, reducing the difficulty of matching the two first plate portions 101 with the inner panel 2 of the tailgate.
[0028] In some embodiments, the third plate portion 110 is provided with a glue groove 111 on the side facing the lower panel 4 of the outer rear door. Using the above technical solution, the third plate portion 110 can be connected to the lower panel 4 of the outer rear door by applying glue, which is easy to assemble.
[0029] In some embodiments, the front side of the reinforcing member body is provided with an upwardly folded fourth plate portion 103, which is used to fixally connect with the inner panel 2 of the rear door. By adopting the above technical solution, the number of connection points between the reinforcing member body and the inner panel 2 of the rear door is increased, which helps to ensure the stability of the connection between the reinforcing member body and the inner panel 2 of the rear door, and can better ensure the installation accuracy of the reinforcing member 1.
[0030] In some embodiments, a fifth plate portion 104 for fixed connection with the inner panel 2 of the rear door is provided at the root of the first extension portion 105. By adopting the above technical solution, the number of connection points between the reinforcing member body and the inner panel 2 of the rear door is increased, which helps to ensure the stability of the connection between the reinforcing member body and the inner panel 2 of the rear door, and can better ensure the installation accuracy of the reinforcing member 1.
[0031] In some embodiments, the reinforcing member body is provided with a first positioning hole 112 and a second positioning hole 113, which are used to cooperate with positioning pins on the welding fixture. By adopting the above technical solution, providing two positioning holes can ensure the installation accuracy of the reinforcing member 1.
[0032] As a specific example, the first positioning hole 112 and the second positioning hole 113 are arranged at intervals in the front-rear direction, and the first positioning hole 112 and the second positioning hole 113 are respectively arranged on the part of the reinforcing member body that is parallel to the first plate portion 101.
[0033] In some embodiments, the first extension 105 is disposed on one side of the reinforcing member body in the left-right direction, and the edge of the other side of the reinforcing member body in the left-right direction is provided with a flange 114. The second extension 109 is disposed on the rear side of the reinforcing member 1. By adopting the above technical solution, the first extension 105, the flange 114, the second extension 109, and the fourth plate portion 103 form a reinforcing structure around the outer periphery of the reinforcing member body, which can further improve the structural strength of the reinforcing member body.
[0034] As a preferred example, the reinforcing member 1 located on the left side of the tailgate has a first extension 105 disposed on the right side of the reinforcing member body, and a flange 114 disposed on the left side of the reinforcing member body. The reinforcing member 1 located on the right side of the tailgate also has a first extension 105 disposed on the left side of the reinforcing member body, and a flange 114 disposed on the right side of the reinforcing member body. By adopting the above technical solution, a better cage-like reinforcing structure can be formed.
[0035] As a specific example, the reinforcing component body is a one-piece molded sheet metal part, and the mounting nut 102 is fixedly connected to the reinforcing component body by welding.
[0036] As a specific example, the first plate 101, the second plate 106, the fourth plate 103, and the fifth plate 104 can all adopt a flat plate structure. The first plate 101 and the inner panel 2 of the back door can be fixedly connected by stacking and welding. The second plate 106 and the outer plate 3 of the back door can be fixedly connected by stacking and welding. The fourth plate 103 and the inner panel 2 of the back door can be fixedly connected by stacking and welding. The fifth plate 104 and the inner panel 2 of the back door can be fixedly connected by stacking and welding. The welding method can be spot welding.
[0037] In some embodiments, a plurality of spaced-apart second plates 106 are provided at the end of the first extension 105, and a downwardly recessed recess 107 is provided between two adjacent second plates 106, with a notch 108 provided at the recess 107. By employing the above technical solution, providing a plurality of second plates 106 can improve the stability of the connection between the reinforcing member 1 and the outer panel of the tailgate. Providing the recess 107 and the notch 108 can reduce the difficulty of matching the plurality of second plates 106 with the upper plate 3 of the outer panel of the tailgate.
[0038] This utility model also proposes a back door, such as Figure 2As shown, the tailgate includes an inner tailgate panel 2, an outer tailgate panel upper plate 3, an outer tailgate panel lower plate 4, and a reinforcing member 1 as described above. The inner tailgate panel 2 is provided with a tail wing lifter mounting portion. A first plate portion 101 is fixedly connected to the tail wing lifter mounting portion, a second plate portion 106 is fixedly connected to the outer tailgate panel upper plate 3, and a third plate portion 110 is fixedly connected to the outer tailgate panel lower plate 4. The outer tailgate panel upper plate 3 is provided with a tail wing lifter through hole 301. When installing the tail wing lifter, the tail wing lifter through hole 301 can serve as the installation channel for the tail wing lifter. The tail wing lifter is installed on the double-layer structure formed by connecting the tail wing lifter mounting portion and the first plate portion 101. After the tail wing lifter is installed, at least a portion of the tail wing lifter is located in the cavity between the outer tailgate panel and the inner tailgate panel, making reasonable use of the cavity space between the outer tailgate panel and the inner tailgate panel.
[0039] In practical implementation, the tailgate outer panel can adopt a one-piece structure, with the upper part of the tailgate outer panel being the upper tailgate outer panel 3 and the lower part being the lower tailgate outer panel 4. Alternatively, the tailgate outer panel can adopt a split structure, with the upper tailgate outer panel 3 and the lower tailgate outer panel 4 fixedly connected together by welding. The split structure of the tailgate outer panel is easier to manufacture. Furthermore, the third panel 110 is fixedly connected to the lower tailgate outer panel 4 by adhesive bonding, providing greater tolerance and facilitating the use of a split structure for the tailgate outer panel.
[0040] This utility model also proposes a vehicle including the aforementioned tailgate.
