Problems solved by technology
[0013] However, in the hatch door opening structure utilizing the constant velocity motion gear ratio, since the interior of the buffer device 4 is high-viscosity hydraulic oil, if the external temperature is relatively low, the hatch opening speed will drop significantly; on the contrary, if the external temperature is relatively high, the hatch door will The opening speed will be relatively increased

Embodiment Construction
[0023] Hereinafter, an example in which the structure for improving the hatch opening speed of the present application is applied will be described in detail with reference to the accompanying drawings.
[0024] Figure 4 In the present application, it is a schematic diagram of the action relationship between the door gear device with constant acceleration gear ratio and the gear of the buffer device meshing with it; and Figure 5 is in Figure 4 A graph showing the change in hatch opening angle as a function of time in .
[0025] Referring to these pictures, in a player with a hatch opening structure with constant acceleration gear ratio, as long as the button on the side of the player body is pressed, the aforementioned hatch 2 opens relatively quickly at the initial stage, but when it reaches the final stop position The entire cabin door opening action will adopt the form of constant acceleration motion.
[0026] That is to say, during the initial stage when the hatch 2 ...

This application relates to the invention of the structure for improving the door opening speed of electronic products such as CD players or cassette tape players; especially the structure for improving the door opening speed of CD players or tape players that use CDs or tapes for signal playback The hatch door opening speed improvement structure in the present application includes the following contents: a hatch door with a gear device on the back and a buffer device meshing with the above-mentioned gear device to buffer the opening speed of the hatch door; the above-mentioned gear device is provided with a deformation gear, and the above-mentioned Corresponding deformation gears are also arranged on the buffer device. The hatch door of the hatch opening speed improvement structure in the present application does not open at a constant speed, but the hatch door opens at a relatively fast initial speed, and then it will be relatively slow when it is about to stop.
Description
【Technical field】 [0001] This is an invention related to the structure for improving the door opening speed of electronic products such as CD players or cassette tape players; especially the structure for improving the door opening speed of CD players or tape players that use CDs or tapes for signal playback. 【Background technique】 [0002] The gear of the buffer device and the gear of the gear device behind the hatch can be adjusted; and the gear ratio of the above-mentioned gears is not a constant velocity gear ratio, but a constant acceleration movement gear ratio; therefore, the hatch does not open at a constant velocity, but The opening speed of the cabin door is relatively fast at the initial stage, and it will be relatively slow when it is about to stop; in addition, in the application of the prior art, the opening speed of the cabin door in cold weather is obviously slow due to the temperature-sensitive buffer gear used inside, and the In high-temperature weather, th...
