We won't say much about the premium of umbrellas, which is beyond the professional scope of Che Jujun. Let's start with their car door device. As the equipment for storing umbrellas, its design fee is definitely not low, which may provide some support for this "65,438+10,000 yuan" umbrella fee.
First, the "official introduction" is a bit ridiculous.
About this device, there is an introduction video circulating on the Internet. From the official population of Rolls-Royce, we generally know that it has the following characteristics:
▎ Putting a wet umbrella in the car is not in line with the identity of Rolls-Royce owners, and we must find ways to remove rainwater;
▎ There are some vents on the door, which can not only make the water with umbrella drip, but also make some residual heat of the engine directly lead into these vents to heat, dry and sterilize the umbrella.
In fact, regarding this introduction, Che Jujun is skeptical. The vent is actually to remove some water by air drying, but there are still a lot of sound insulation cotton, electrical components and wiring harnesses in the door. In fact, we don't want "steam" in it.
For example, the interior of the dashboard, which is the most susceptible to moisture in a car, is required in this way. We know that the air conditioning and ventilation system is installed inside the dashboard, and the pipes of this ventilation system will inevitably leak or condense because they stick together. In order to ensure that the metal dashboard beam, various electrical components and wiring harness are not affected by moisture, we will require the ventilation system to conduct a "dew test".
The condensation test is simply to test whether there will be condensate dripping on the air conditioning pipeline when the air conditioning system is blowing cold air. Our previous Chery models suddenly fell into the "rusty door" of the dashboard beam, which should not be! Wen | The reason why JUV dashboard beams are easy to corrode is directly related to the relatively high humidity inside the dashboard.
It stands to reason that the interior of the car door is smaller and there is soundproof cotton that is more susceptible to moisture. At this time, it is definitely inappropriate to design vents, so Che Jujun thinks it is more appropriate to design an independent water guide tank.
In addition, the introduction of engine waste heat is also very strange. We know that Rolls-Royce umbrellas are designed at the front and back doors, but the design of front and rear drives is too difficult to lead the engine waste heat to the back door.
Although the front door is still close to the engine, the door is connected to the body through a hinge. From the door structure, it is almost impossible to have a ventilation duct connecting the engine compartment and the door to transfer heat. Judging from the door structure of Rolls-Royce, Che Jujun did not see a similar ventilation duct.
