Description

Metal embedded injection molding composite structure's vehicle back panel and vehicle Technical Field The utility model relates to the technical field of vehicle manufacturing, in particular to a vehicle back panel with a metal embedded injection molding composite structure and a vehicle. Background In modern automotive manufacturing systems, the back panel serves multiple key functions as an important component of the body structure. Firstly, the back coaming provides installation space for a spare tire and a vehicle-mounted tool to ensure the practicability of the vehicle, secondly, the back coaming can absorb impact energy in a collision accident and reduce deformation in the vehicle so as to protect the safety of passengers, and in addition, the back coaming also provides structural support for a rear vehicle body to ensure the rigidity and the stability of the whole vehicle. However, the main stream of materials of manufacture for the current back wall panel are still metallic (e.g., plain steel or high strength steel). Although the metal material can meet the strength requirement, the high density characteristic of the metal material leads to the fact that the weight of the back panel is large, so that the quality of the whole automobile is improved, and the metal material is contradictory with the trend of light weight development of the automobile industry. The lightweight design can not only remarkably reduce energy consumption, but also improve endurance mileage and control performance, and especially under the background of rapid popularization of new energy automobiles, the importance of the lightweight technology is more and more prominent. In addition, the maintenance cost of the metal back panel is high. Once damaged, it is often necessary to repair by means of a cut change, which not only increases maintenance costs, but can also lead to substantial devaluation of the vehicle. Therefore, how to realize the light weight of the back panel on the premise of ensuring the safety performance and reduce the maintenance cost at the same time becomes a technical problem to be solved in the field of automobile design. Disclosure of utility model The utility model aims to provide a back panel of a vehicle, which has the advantages of light weight, low cost and the like. Another object of the present utility model is to provide a vehicle employing a rear wall panel that is lightweight and low-cost, thereby reducing the weight and maintenance costs of the entire vehicle. In order to achieve the above object, according to one aspect of the present utility model, there is provided a vehicle back panel of a metal insert injection molding composite structure, comprising a metal member, the left and right end portions of which can be connected to side walls of a vehicle and the middle portion of which can be mounted with a tail gate latch of the vehicle, an injection molding member, the top of which is formed as a double-layer fixing portion including a first layer and a second layer, and a connection portion for connecting to a rear floor of the vehicle is further formed under the double-layer fixing portion, wherein the metal member is positioned between the first layer and the second layer such that the first layer and the second layer become an outer wrapping layer, closely fit to a surface of the metal member, and thereby form a sandwich structure, thereby fixing the metal member to the top of the injection molding member. In some exemplary embodiments, the metal member includes a first plate, a second plate having a front edge connected to and extending rearward from an upper edge of the first plate, wherein a rear portion of the second plate is inclined upward and exposed to an outer wrap for mounting a weather strip, and both end portions of the rear portion of the second plate are each formed with a first connection hole, two reinforcing plates respectively located at both end portions of the metal member, a front edge of each reinforcing plate being connected to both end portions of the first plate, an upper edge being connected to a front portion of the second plate, and two end plates respectively located at both end portions of the metal member, and each end plate is formed with a second connection hole, wherein each end plate extends outward of the metal member from a rear edge of the reinforcing plate on the same side thereof, and an upper edge of each end plate is connected to an end portion of the rear portion of the second plate, wherein the first connection hole and the second connection hole are used for penetrating a bolt.
