Portable Toilet for New Energy Vehicles
The utility model patent for 'Vehicle-mounted Toilet and Vehicle' applied for by Seres Automotive Co., Ltd. provides an emergency toilet device that can be stored under the seat, but it is currently unclear whether it will be installed in mass-produced vehicle models.
Device Composition and Features
This emergency toilet device consists of a toilet body and a slide rail assembly. Through the telescopic function of the slide rail, users can pull the toilet out from under the seat when needed and easily push it back to hide it after use. This design takes up almost no effective space inside the vehicle and stands out in terms of integration and concealment. Compared to the 'vehicle-mounted toilet' concept proposed by Jishi Automotive, which stores a toilet seat in the central storage box and requires the use of disposable plastic bags, resembling a portable toilet storage solution, Seres' solution is more advanced in overall design.
Patent Status
This patent was applied for on April 22, 2025, and the authorization process was completed on April 10, 2026, with the authorization announcement number CN224104011U. However, it has not yet been announced whether this device will be installed in mass-produced vehicle models, which means there is still uncertainty regarding its actual application in real vehicles.
Practical Issues for Mass Production
If this device is to be mass-produced and installed in vehicles, there are still many practical issues that need to be addressed urgently. Privacy protection is the primary concern. Given the relatively small space inside the vehicle, providing sufficient privacy for users when using the toilet to avoid embarrassing situations requires a reasonable design solution. Odor treatment cannot be ignored either. If the odors generated during use cannot be effectively treated, it will seriously affect the air quality and user experience inside the vehicle. Cleaning and filtration system design is also crucial. It is necessary to ensure that the toilet can be cleaned conveniently and thoroughly after use and that the filtration system can effectively filter sewage and impurities to prevent pollution of the vehicle's interior environment.
