Through E-Legend, Peugeot has created a vehicle that evokes the nostalgia of French cars and looks like it comes from the future. For example, the broken blue velvet interior looks a lot like Elvis Presley. At the same time, it shakes 16 screens on doors, sunshades and floors, and the wooden steering wheel shrinks back into the dashboard, so you can let it drive or control itself. What you want to do most is the latter, because a 456 horsepower electric motor can push it to 62 mph in four seconds and then drive 373 miles between charges.

The heat preservation of the greenhouse is very high in summer, so all the vents around the vegetable greenhouse must be opened. If the temperature is too high, the top of the vegetable greenhouse can be covered with sunshade net to cool down. In the sunny day, the temperature in the shed should be measured in time. As soon as the temperature rises to more than 30 ℃, open the ventilation vents on both sides and adjust the vents to stabilize the temperature in the shed at 25 ℃-30 ℃ as far as possible. Take light enhancement measures to increase light intensity and prolong light time; select agricultural film with high light transmittance and wipe it frequently to ensure that the surface of agricultural film is clean; cover white plastic film; hang reflective curtain on the back wall; prune and pick leaves in time to enhance the light transmittance of the field.

Selecting suitable greenhouse system materials according to local conditions the greenhouse is composed of various systems and materials working together. The standard planting greenhouse system includes external sunshade system, internal sunshade heat preservation system, top natural ventilation system, wall natural ventilation system, fan water curtain forced ventilation system, high waist spray cooling system, heating system, internal climate circulation system, plant root climate circulation system, carbon dioxide generation and supplement system, planting trough system, water and fertilizer integration system and so on.

Due to the use of reflective aluminum foil, sunshade can play a better heat insulation and shading effect. Compared with the car heat shield sold in the market at the same time, it is more flexible and convenient to unfold and fold, and is more suitable for car owners who are in a hurry and are afraid of trouble. When the vehicle is parked, as long as the attached sucker or rely on static electricity, the sunshade can be sucked on the front and rear windshield, which can effectively protect the dashboard, leather seats and other interior equipment while preventing direct sunlight from raising the temperature in the car. At present, in addition to the single sale of front windshield aluminum foil sunshade, but also launched a special car customization service, including windows, rear gear and other positions, the price is not expensive, only tens of yuan to hundreds of yuan. It is worth noting that when buying, it is best to turn on all of them in the light or sunlight to carefully check for damage and leakage.

One of the simplest items in the high temperature test is the exposure test, in which the vehicle is parked in the hot sun with the front facing west, and the temperature display patch is affixed to the critical parts of the vehicle, such as engine cover, dashboard, deflector, and so on, and the temperature in the car is as high as 70 or 80 degrees. Then test the door handle, dashboard, sunshade, air conditioning outlet and other internal and external accessories for abnormal sound or efficacy failure.

At present, spray-free plastics have been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field. Bioplastics bioplastics are produced by using original plants as raw materials, such as sugar cane and corn, under the action of microorganisms. Commonly used plastics are generally synthesized from petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics are prepared into automobile interior parts to reduce the amount of VOCs volatilization in the car because of the use of renewable materials with low toxicity and low harm. In addition, this bioplastic can be decomposed to facilitate subsequent recycling, so it is a more environmentally friendly type of plastic.

The two symmetrical circular instruments under the sunshade arch of the first dashboard are simple and clear, while under the sunshade arch of the second dashboard is a large liquid crystal display screen to display satellite navigation, reversing radar, entertainment systems and various driving information. Due to the use of i-drive information control system, the center console looks very regular, not so many complicated buttons and knobs.

Under the premise of meeting the design requirements of the building, adding external sunshade panels, awnings and appropriately increasing the pick-out length of the southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.

Avoid direct sunlight and high temperature in the car. Dashboards, which control these areas, are mostly made of engineering plastics. plastics will age and fade after being exposed to the sun for a long time. Although we will do strict aging tests during development, it is good to pay more attention to them. So it is necessary to always have a sunshade mat.

In terms of interior decoration, the Jettos X90 Zilong has not changed much compared with the cash model, but some adjustments have been made in the details, especially the addition of brown-red interior color matching and the new decoration board of the center console, which has improved the luxury of the whole car a lot. In terms of materials, Jettos X90 uses 118 kinds of interior materials in dashboards, carpets, door guards, ceilings, columns, steering wheels, shock cushions, seats, sunshades, etc., and is equipped with CN95 air conditioning filter elements, dual-channel laser PM2.5 sensors and negative ion generators to ensure the air quality in the car.

Strength description: please wear hiking shoes or travel shoes, do not wear leather shoes, high heels, backpacks, sunshade hats, the route is about 8 kilometers, rising and falling are about 400 meters. Enjoy the lace and play, have a picnic after enough, there is no danger in the route, just be careful, please listen to the arrangement of the team leader to ensure safety.
