Description

Technical Field

[0001] The utility model relates to the field of automobile door design, in particular to a lightweight structure of an automobile door. Background Art

[0002] In the development of new models, each component of the car body needs to be developed separately for molds, fixtures, and inspection tools for body manufacturing and inspection. Due to factors such as the market size and estimated production of new models, many car companies cannot afford the development and manufacturing costs of molds, fixtures, and inspection tools in the development of new models. In order to reduce the one-time investment in vehicle development and shorten the development cycle, the development of body parts can optimize the structure and simplify the design process.

[0003] In the past decades of automotive tooling development, automobile manufacturers have used many different methods to develop molds, fixtures, and gauges, which require long cycles and large investments. Some products may lose their market competitiveness and fail before they are launched on the market, wasting a lot of manpower, material, and financial resources. For this reason, we have proposed a lightweight structure for automobile doors. Utility Model Content

[0008] 1. In the utility model, the lightweight door structure adopts an optimized design, simplifies the structural idea, retains the inner and outer panels, door lock fixings, removes other parts, combines the water-cut reinforcement plate B, the anti-collision plate B, and the anti-collision rod B as a reinforcement frame, reduces the number of molds, can save money, and improve production efficiency;

[0009] 2. Sheet metal stamping parts can also be made of aluminum plates or thermoplastic plates. The advantages of profile frame forming parts are that they are lightweight and high-strength, and at the same time have good plasticity and adaptability, and can easily adapt to various complex structural requirements.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 The figure shows a preferred embodiment of the utility model, a lightweight structure of a car door, including a door body 8 and a reinforcement frame 11, the door body 8 includes a door outer panel 9 and a door inner panel 10, a door lock fixing part 15 is fixedly installed on one side of the door inner panel 10, the door body 8 is made of aluminum plate or thermoplastic plate, the reinforcement frame 11 is fixedly installed between the door outer panel 9 and the door inner panel 10, and the reinforcement frame 11 includes a water-cut reinforcement plate B12, an anti-collision plate B13 and an anti-collision rod B14.

[0017] Specifically, a gap matching the size of the reinforcing frame 11 is provided between the door outer panel 9 and the door inner panel 10 for accommodating the reinforcing frame 11. The matching of the sizes between the two enables the reinforcing frame 11 to support the door outer panel 9 and the door inner panel 10 more stably.

[0018] In this embodiment, Figure 1As shown, it should be noted that the traditional structure door contains outer panel 7, inner panel 1, reinforcement plate 2, water-cut reinforcement plate 3, anti-collision beam A5, anti-collision rod A6, lock mounting plate 4 and other parts, which are formed by stamping to meet product requirements; then they are welded together through special fixtures, and then all processes of the door sheet metal assembly are completed through gluing, edging and repair welding. During the period, it is also necessary to use special inspection tools for inspection and acceptance before it can be transferred to another process. The whole process requires a lot of money and time.

[0019] In the utility model, Figure 1-3 As shown, the lightweight door structure adopts an optimized design, simplifies the structural concept, retains the inner and outer panels, door lock fixings 15, removes other parts, and combines the water-cut reinforcement plate B12, anti-collision plate B13, and anti-collision rod B14 into a reinforced skeleton 11, reducing the number of molds, saving money, and improving production efficiency; the advantages of the profile skeleton forming parts are its lightweight and high strength, as well as good plasticity and adaptability, which can easily adapt to various complex structural requirements.

[0020] In addition to sheet metal stampings, the inner and outer panels of the door can also be made of aluminum plates or thermoplastic plates. They are not only lightweight and high in strength, but also have extremely high production efficiency. They can be assembled with the frame after forming, saving the investment in hemming machines or hemming molds, reducing the number of parts and the number of tooling accordingly, which is very beneficial for improving product quality and production efficiency. All changes in materials and reductions in parts greatly reduce the weight of the entire component and achieve lightweight.
