Dong Qingjun thought for a while and said: "There are still two thousand. Director Guo and his colleagues are doing the sensors and electronic control. We just made requests, so we spent some money on researching airbag materials and gas generators."
Li Wenjun smiled and called Qin Hongling: "Give Dong Qinjun and the others another 20,000."
Dong Qingjun and others rubbed their hands: "Wow, there are another twenty thousand."
Then I took the money and went to study seat belt airbags with great enthusiasm.
Li Wenjun looked at the three of them walking out of the garden below, arm in arm, and smiled.
This is the age when you don't have to be afraid of anything, just move forward, and everything depends on your own mood and interests, without caring about any interests.
In two or three years, once you get married and have heavy responsibilities on your shoulders, it will be difficult to regain this purity.
Dong Qingjun and the others hid a deflated airbag in the seat belt, and then the airbag at this location did not need to have an explosion point, and could be directly triggered to inflate.
The effect is pretty good.
Han Weijun greatly praised Dong Qingjun.
This time it was obviously much more sincere than last time.
After all, as a person with children, he was very touched to see someone caring so much for their children's safety.
Then the people who had been waiting to watch the excitement sighed, they didn’t expect that these three young boys just spent 30 to 50 thousand to accomplish this thing.
Li Wenjun is really an evil capitalist!
-----
The team responsible for opening the skylight said they had made the first version and invited Li Wenjun to take a look.
When Li Wenjun entered, he saw the protruding skylight on the roof of the car from a distance, which looked like a machine gun muzzle on top of a bunker.
Li Wenjun asked: "What is this state?"
Liu Dongsheng scratched his head: "Close state."
Li Wenjun said: "Open it and take a look."
Liu Dongsheng went over, opened the padlock, and then used a bracket to prop up the skylight like a tent.
Li Wenjun wanted to laugh, but was afraid of damaging their self-confidence. He touched his forehead and said, "No. When parking and closing the sunroof, the side and front should look the same as an ordinary car. The sunroof cannot be seen protruding. You cannot go out when it is open. If it protrudes too much, it is unsafe and can easily fall out, or the bracket may break and fall off, hitting people. Secondly, the wind resistance is too great, which affects driving speed and increases energy consumption.”
Liu Dongsheng grimaced: "It's impossible."
Li Wenjun said: "Would your house protrude a bunker from the wall to install a glass window? Go back and figure out how your sliding windows work."
Then Liu Dongsheng scratched his head and kept pushing and pulling the aluminum alloy window for several days after going back.
"Squeaky..."
"Chirp ah ah..."
The sound makes one's teeth ache and makes one feel panicked.
The neighbors couldn't stand it, so they recommended Han Weijun, who lived downstairs from Liu Dongsheng, to knock on Liu's door and talk to him.
Han Weijun saw that his face was gray and he couldn't laugh or cry: "I said Dongsheng, if you really want to play with the window, at least put some oil on it. Or get a roller. The sound is really..."
Liu Dongsheng grabbed Han Weijun's arm: "Just in time, Director Han, you are here. I have something I want to ask you."
Han Weijun: "Say."
Liu Dongsheng: "Director Li said that when the sunroof on the car roof is closed, it cannot protrude. Let me think about the sliding windows at home."
Han Weijun knew that Liu Dongsheng was thinking about this, and he became interested when he heard it. He followed Liu Dongsheng to the window and said, "Does Director Li mean to move it sideways like a sliding window, not push it out?"
Liu Dongsheng: "I think so too. Sliding windows are not a flat surface either."
"That's right. That's right. The two windows must have their own tracks, otherwise the two windows will be against each other and cannot be pushed." Han Weijun frowned and began to push and pull the window, thinking about this matter.
Qiu Yan waited for Han Weijun to go back to eat. After waiting and waiting, Han Weijun didn't come back, so she asked Han Dongdong to go up and call Han Weijun.
Han Dongdong came back and said, "Dad is playing with the sliding window with Uncle Liu."
Qiu Yan couldn't laugh or cry: "Ah, no. Didn't you come here to persuade Uncle Liu?"
After Han Weijun finished lunch, he came over to spend the afternoon thinking with Liu Dongsheng.
Liu Dongsheng's son Liu Ping watched for a while, then felt bored and went to play with the toys by himself.
Liu Ping was also playing with a lift from the series of electric construction machinery produced by the "Wenjun Industrial" toy factory.
Press a button, and the platform, which looks like a flat plate, will split into two pieces, and then one of the pieces will slowly rise. During the rising process, guardrails will also rise together to protect the safety of people standing on it.
There are three levels of height.
After rising to any height and stopping, you can press the descent button at any time.
The platform will slowly lower again, and the fence will retract, becoming a flat plate again.
All the machinery produced by "Wenjun Industrial" has toy models.
Firstly, it satisfies children, and secondly, making a model can also facilitate machine manufacturers to study how to improve it, so that it is easy to use.
Han Weijun and Liu Dongsheng watched Liu Ping move up and down with joy, and suddenly they felt enlightened.
"Dongsheng, it's a flat surface when closed. When you open it, you can lower it a little inside and then move it to the side."
"Yes, yes. I think so too."
"In this case, the windows can be opened half way without affecting driving."
The two of them became more and more excited as they talked. Regardless of whether it was a holiday or not, they ran to the factory to put their ideas into practice.
Then it took a few days to succeed, and Li Wenjun was invited.
Li Wenjun tried it carefully and praised repeatedly: "Not bad, not bad. It's good to be able to do this in such a short time."
Liu Dongsheng was excited and a little shy, and replied: "There is only one problem, that is, the baffle of the stainless steel plate is too thick. The stainless steel window cannot be opened when the glass window is opened, and the glass window cannot be opened when the stainless steel plate is opened. The same thing happens when it is closed. We tried many Not even once.”
Li Wenjun couldn't help laughing: "Then don't use the stainless steel plate and replace it with a shading plate. The aviation plexiglass recently developed by the Materials Research Institute is strong enough to be used as a skylight."
Liu Dongsheng said: "Then I can get a piece and try it on?"
Li Wenjun nodded: "Okay. Install all the sunshades, the operation smoothness of the sunroof in the fully open, fully closed, and half-open states, and the rubber strips for sealing must be perfect. The rainy season will come soon. Now, let’s take advantage of the rainy season to test the sealing effect.”
The rainy season of 1990 arrived in Cha County as promised, lasting for several days.
The rain finally stopped today, so Liu Dongsheng and the others asked Li Wenjun to inspect the finished roof window early in the morning.
Li Wenjun was busy in a meeting with finance and couldn't leave.
As soon as Tao Guangming heard that he was inspecting the roof windows of the car, he immediately volunteered and said he had time to go.
Li Wenjun thought it would be good to experience it with someone else. After all, he would not be the only customer in the future, so he agreed.
Tao Guangming came to the test track of the automobile factory excitedly.
He never imagined that he would leave crying in ten minutes.
