A heat protection product with at least one seam, comprising at least a textile layer of polymer fibers from a thermoplastic material; a polymer layer; a metal layer;

wherein said at least one seam is obtained by welding.

A vehicle bottom structure includes heat shield plate, which is arranged between a vehicle component and an exhaust pipe, and two undercovers, which are arranged on the opposite sides of the exhaust pipe in the vehicle width direction. The heat shield plate has a covering portion, two heat-shield-plate fastened portions, and two heat-shield-plate coupling portions. The covering portion covers the exhaust pipe. The heat-shield-plate fastened portions are each fastened to the corresponding one of the undercovers. The heat-shield-plate coupling portions each couple a corresponding lower end of the covering portion to the corresponding one of the heat-shield-plate fastened portions. Each heat-shield-plate coupling portion includes a section that has a shape that becomes higher toward the corresponding undercover in the vehicle width direction. The heat-shield-plate fastened portions are each located above the corresponding lower end of the covering portion.

To form the electromagnetic shielding system of electric vehicle's drive motor, the drive motor's power surge protection devices, signal lines and control line protection devices are installed between the outer shield and the drive motor to absorb the induced current which is caused by the motor's electromagnetic field around the power lines and signal lines. In this way, the induced current may not penetrate the shield and form another strong magnetic field, and the drive motor's electromagnetic radiation intensity might meet the exposure level of the medical standard 04 T in 0.6 meters. Thus drivers and passengers tend to have safer driving in electric vehicles for a long time. Without radiation damage to human body, electric vehicles may be more popular. After the popularity of electric vehicles, electric vehicles will replace the existing gasoline and diesel fuel vehicles to slove the global environment pollution problem fundamentally.

A protection device for a passerby to prevent injury from an extended section of the slide out of any mobile living quarters such as a recreational vehicle is disclosed. The slide out of the recreational vehicle comprises an L-shaped tubular member with a hollow inner section to conformingly fit the lower sides of the external sharp sections. The tubular member is configured to be fixedly attached to the lower sides of the sharp edge. The tubular member is made from a cushioning material configured to provide head protection to a passer-by walking near the recreational vehicle.

A method for producing an acoustic protection screen for a motor vehicle engine, comprising providing a reflective metal thermal protection sheet having a plurality of micro perforations, providing a batt of fibres containing a thermosetting resin, superposing the metal thermal protection sheet and the batt in a first thermocompression mould, compressing the batt by binding the fibres together, in order to form a thermal insulation layer, and combining the metal thermal protection sheet with the layer using the thermosetting resin, placing the thermal protection shell against an upper wall of a second mould, the wall being provided with out-gassing vents, the sheet facing toward the wall, injecting into the second mould an air-porous polyurethane foam precursor mixture, the lower wall of the second mould being free of any fluid-tight coating, after the foam has expanded, demoulding the screen obtained, in which screen the foam forms a support overmoulding the layer.

A computing system for a vehicle includes one or more processors and a memory for storing data and program instructions usable by the one or more processors. The one or more processors are configured to execute instructions stored in the memory to determine if a virtual straight line connecting a predetermined location within a vehicle with a light source external to the vehicle passes through a window of the vehicle. If the straight line passes through a window, it is determined if the straight line will pass through any deployable vehicle shade if the shade is deployed. If the straight line will pass through a shade if the shade is deployed and the shade through which the straight line will pass is not already deployed, the vehicle may be operated so as to deploy the shade through which the straight line will pass if the shade is deployed.

An apparatus and a method are provided for an alternative fuel system, comprising a plurality of fuel tank assemblies interconnected with fuel lines; the plurality of fuel tank assemblies comprising a CNG fuel tank and a fuel tank shield; wherein a first and second fuel tank assembly is disposed immediately in front of a rear wheel assembly, and a third fuel tank assembly is disposed immediately behind the rear wheel assembly.

A two-track vehicle having a chassis on the lower face of which a component is arranged that is sensitive to scraping the road surface, the outer contour jutting out downward from the lower face of the chassis in the direction of the road surface by an offset variable and the component being covered by a base portion of a cover element to protect the component from scraping the road surface. At least one edge portion of the base portion of the cover element is laterally extended in a vehicle transverse direction, the edge portion forming a scraper stop that juts out downward from the cover element base portion in a direction onto the road surface by a vertical offset so that, when the lower face of the vehicle scrapes the road surface, the cover element base portion remains substantially out of contact with an interference contour on the road surface.

A sound production device for a vehicle includes: a speaker that causes a diaphragm to vibrate thereby producing sound; and a housing receiving the speaker and having a sound passage through which the sound produced by the speaker passes and a sound emission hole that causes the sound passed through the sound passage to externally emit. Plural resonant chambers having different resonant frequencies are defined in the sound passage, such that the sound passage has a labyrinth structure that is able to prevent a foreign substance form entering the diaphragm from the sound emission hole.

A damping assembly in a vehicle is provided. The damping assembly comprises a rod; a spring disposed along a lengthwise direction of the rod; and a buffer pad including a connection end coupled to the rod and an external end opposing the connection end and including a buffer surface. The spring is coupled with the rod and configured to be retracted and extended with the rod at the lengthwise direction.
