Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a lightweight and environmentally friendly plastic part for new energy vehicles. Background Technology

[0002] New energy vehicles refer to vehicles that use non-traditional fuels as power sources, mainly including electric vehicles, plug-in hybrid electric vehicles, and hydrogen fuel cell vehicles. These vehicles aim to reduce dependence on fossil fuels, reduce greenhouse gas emissions, and improve energy efficiency, thereby achieving the goals of environmental protection and sustainable development. Among them, the spare tire box is one type of lightweight plastic automotive component.

[0003] Chinese patent discloses a lightweight plastic automotive component (authorization announcement number CN222202713U). This patented technology includes a housing and a cover plate that snaps onto the top of the housing. The top of the housing has a threaded cavity, allowing the spare tire to be fully exposed inside the housing, increasing the force-bearing area and making it more stable and reliable during handling, preventing it from slipping off. When the bottom tray descends until the bottom airbag contacts the bottom of the threaded cavity of the housing, the upper airbag inflates to compress and limit the lower surface of the spare tire, and the top airbag at the bottom of the cover plate compresses and limits the upper surface of the spare tire, ensuring that the spare tire inside the housing will not shake or be damaged during vehicle operation. When the housing is placed inside the vehicle, the bottom airbag is forced to compress, causing the airbags on the outer wall of the housing to inflate and press against the vehicle body. This allows the spare tire storage box to be fitted to different vehicle body sizes, making it widely applicable.

[0004] However, most existing automotive parts use airbags for spare tire positioning. Airbags are prone to leakage or depressurization during use, failing to protect the spare tire. For example, the aforementioned comparative document uses an airbag for spare tire positioning. Therefore, those skilled in the art provide a lightweight, environmentally friendly plastic component for new energy vehicles to address the problems mentioned in the background section.

It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1-4 As shown, a lightweight and environmentally friendly plastic component for new energy vehicles includes a cylindrical body 1 and a cap 2 disposed on top of the cylindrical body 1. A base 11 is provided at the bottom end of the cylindrical body 1, and a placement groove 13 is provided at the upper end of the cylindrical body 1. A positioning ring 12 is provided on the upper surface of the cylindrical body 1 outside the placement groove 13, and a connecting ring 4 is provided on the outside of the cap 2. By rotating the connecting ring 4 on the external threads of the cylindrical body 1 and the cap 2, the cap 2 and the cylindrical body 1 can be sealed to protect the spare tire of the vehicle. Two sets of limiting plates 3 are symmetrically arranged on the lower surface of the cylinder cover 2. A positioning plate 31 is installed on the outer side of the limiting plate 3. A positioning bolt 33 is provided on the lower surface of the positioning plate 31. A positioning hole 22 is symmetrically opened on the lower surface of the cylinder cover 2. A fixing hole 32 is opened inside the positioning plate 31. The limiting plate 3 can be installed by threading the positioning bolt 33 with the positioning hole 22. Thus, the limiting plate 3 can be used to protect the spare tire of the car inside the cylinder 1.

[0018] like Figure 1 As shown, both the outer surface of the cap 2 and the outer surface of the cylinder 1 are provided with external threads, and the inner side of the connecting ring 4 is provided with an internal thread that engages with the external thread. The connection between the external thread and the internal thread can be achieved by connecting the cap 2 and the cylinder 1 through the connecting ring 4.

[0019] like Figure 2 and Figure 4 As shown, a positioning groove 21 is provided on the lower surface of the cylinder cover 2, and a positioning ring 12 is embedded inside the positioning groove 21. This arrangement achieves the purpose of positioning and connecting the cylinder cover 2 and the cylinder body 1 by embedding the positioning ring 12 inside the positioning groove 21.

[0020] like Figure 3As shown, the limiting plate 3 is semi-arc-shaped, and a protective rubber pad is provided on the inner side of the limiting plate 3. Four sets of positioning holes 22 are symmetrically opened on the lower surface of the cylinder cover 2. The upper end of the positioning bolt 33 passes through the fixing hole 32 and is embedded in the positioning hole 22 and threadedly connected to the positioning hole 22. By the upper end of the positioning bolt 33 passes through the fixing hole 32 and is embedded in the positioning hole 22 and threadedly connected to the positioning hole 22, the positioning plate 31 on one side of the limiting plate 3 can be installed on the lower surface of the cylinder cover 2, and then the limiting plate 3 can be installed to achieve the purpose of positioning the spare tire of the car.

[0021] like Figure 1 As shown, the base 11 is made of rubber. The rubber base 11 can protect the cylinder 1, that is, protect the spare tire inside the cylinder 1.

[0022] The working principle of this utility model is as follows: When using this lightweight and environmentally friendly plastic component for new energy vehicles, firstly, the cylinder 1 is installed in the trunk of the car. The distance between the two limiting plates 3 is adjusted according to the size of the spare tire. During adjustment, the fixing hole 32 in the positioning plate 31 is aligned with the positioning hole 22 at different positions on the lower surface of the cylinder cover 2. The positioning bolt 33 is threaded through the fixing hole 32 and connected to the positioning hole 22, thus enabling the limiting plate 3 to be installed on the lower surface of the cylinder cover 2. After installation, the cylinder cover 2 is installed on the cylinder 1, that is, the positioning ring 12 on the cylinder 1 will be embedded in the positioning groove 21 on the lower surface of the cylinder cover 2. This achieves the positioning installation of the cylinder cover 2 and the cylinder 1. At this time, the inner side of the limiting plate 3 will contact the outside of the car spare tire to achieve its limiting protection. At the same time, the connecting ring 4 on the outside of the cylinder 1 is threaded towards the position of the cylinder cover 2, thus achieving the purpose of locking the cylinder cover 2, thereby further protecting the car spare tire inside the cylinder 1.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
