Today to disassemble is The Dalyou A900, mainly look at the KBS 3.0 button system it uses, which is a hardware patented technology optimized for the mouse core buttons, in view of the fact that domestic manufacturers are currently focusing on active button technology, and KBS 3.0 is still unique compared to Logitech and Razer, it is necessary to introduce the design that shows the wisdom of the Chinese people: dual-axis cantilever structure.
Our A900 is the earliest beta version and some of the external details of the official listing are a little different, so the relevant functional tips at the bottom are not yet available, but the hardware and firmware versions are the same.
The tail of this beta version is a lampshade and supports RGB LOGO, and the official version has removed the backlighting here.
A900 as a flagship model, the feel part of the shell using the popular one-piece lid + split buttons, a bit interesting, the entire button seems to become a module, the side keys are also integrated.
Starting from A960, Daryou upgrade equipment to achieve plastic rapid prototyping process, like some foreign high-end products to produce ultra-thin shell without punching holes, to achieve lightweight mouse body structure, combined with other examples in the past, Daryou's focus on the mouse is indeed higher than most other domestic brands. With the support of the high-speed injection molding machine, the shell weight of the A900 can be reduced by 20 to 30%.
Turn the button module over, this is the KBS 3.0 system, one of the highlights of this mouse. A pair of cantilever arms made of orange POM (less rotational resistance with good self-lubrication), with a steel shaft at both ends of the front and rear, pass through the black base and white buttons, forming a double-headed shaft-style linkage structure, and placing the key column (trigger point) at a certain point between the cantilevers.
(The cantilever side of the right button has made some cuts due to the reason of artificial tuning test, do not care) In this way, when the human hand presses in different positions on the button, the two shaft structures can rotate with each other according to the change of the trigger point, and play the characteristics of the axis button with less resistance and less effort, which is the mystery of the dual axis cantilever, and it is more intuitive to demonstrate the principle of action with Gif.
In this way, the result of the emergence of the player experience end is that no matter the large hand is small or the grip is different, the trigger will be more labor-saving behind the original laborious button, without specially extending the force arm, and its actual effect can be verified from our compression test data.
In addition, a spring is added to the mezzanine space of the button and the middle frame to provide assistance, and the micro-motion trigger point can be attached to the top button at all times, thus avoiding empty travel. Many mouse button tunings such as BattleBlade 3, Viper Ultimate, etc. have springs that play this role, but they are relatively simple, there is no dual-axis suspension, and in Daryou's button system, there is no dual-axis cantilever or KBS 2.0.
We take the cantilever off and continue to remove the buttons to make this structure clearer. The left and right button plates are more than a pair of bases for connecting cantilevers than the general mouse, and its head and tail have a corresponding limit structure, which can ensure the stability and efficiency of the button continuous triggering, and the wear-resistant gasket is added to the key post, because it is a prototype, the thickness and area of the gasket are not very accurate.
This is the entire key system of Daryou A900, in the concept is not to lose foreign brands, adhere to and strive for excellence in the domestic high-end is capable of having hope. The principles and features of KBS 3.0 are basically introduced, and then take a look at other workmanship and materials.
Compared with the button system, the bottom cover and the motherboard are relatively intuitive, A900 uses a black square PCB board, the tail with storage slot, the parts are relatively front, and then through the larger weight of the 500mAh lithium battery to balance the end and tail, to ensure that the center of gravity is centered.
Dalyou autonomous micro-motion, HUANO OEM 50 million times life, hollow roller with a game-grade black core encoder provided by TTC with 1M life.
A900 as the first domestic high-end three-mode gaming mouse on the market, the configuration is not low, by the original phase PAWA3370 + Craftsman Alliance COMX CX52850 system chip composed of three-mode solution, support wired, 2.4G and Bluetooth 5.0, from the use and market feedback, this single chip three-mode can also be.
From the point of view of disassembly, A900 has a very upward attitude in terms of ideas and solutions, the characteristics of the entire mouse are also relatively distinct, there is no excessive stacking and pursuit of fancy, the material and workmanship are also remarkable, the use is reasonable, and I hope that some of the flash points on it can be maintained to other products.
