Description

Auxiliary opening device for motorcycle seat cushion

【Technical field】

The invention relates to an auxiliary opening device for a motorcycle seat cushion, in particular to an auxiliary opening device for a seat cushion that can increase the opening angle of a motorcycle seat cushion.

【Background technique】

Existing motorcycle seat cushions can utilize the storage space provided under the seat cushions to provide storage space for items such as safety helmets and gloves, in addition to the required seating space for the rider and the rider. The function of storage is actually an important structure that is frequently used and indispensable in motorcycle construction. Among them, the design of the general seat cushion mostly adopts the tilt-and-turn design, and the seat cushion is designed as the cover of the storage box. It provides a loading function. When you want to use the storage box, you only need to turn the seat cushion open to place or take items. When the seat cushion is closed, it can return to its original shape. For larger motorcycles, because the seat cushion is relatively large and heavy, some operators have developed a motorcycle seat cushion opening device 1 that can assist the rider to open the seat cushion, as shown in Figure 1, including There is a cushion 11, a storage box 12 and an air pressure rod 13. The seat cushion 11 has a driver's seat 111 and a passenger seat 112 , and the storage box 12 has a front object space 121 and a rear object space 122 . It is mainly to set an air pressure rod 13 between the seat cushion 11 and the storage box 12, the upper fixed end 131 of the air pressure rod 13 is arranged under the seat cushion 11 driver's seat 111, and the lower fixed end 132 of the air pressure rod 13 is It is fixed between the front object space 121 and the rear object space 122. When the seat cushion 11 is unlocked and lifted up at a certain angle, it can be slowly expanded by the pre-pressure of the air pressure rod 13, and the seat cushion 11 can continue to go up automatically. When the seat cushion 11 needs to be closed when it is opened and fixed at a set angle, the seat cushion lock can be locked and fixed by pressing down on the seat cushion 11 .

Existing motorcycle seat cushion opening device 1, by above-mentioned structure, though can reach the purpose that seat cushion 11 is opened, yet, the front upper end of seat cushion 11 bottom plate is the upper fixed end 131 of air pressure bar 13, and air pressure The stretching action area of the rod 13 is also the position of the driver's seat 111 of the seat cushion 11, so reducing the combined thickness of the seat cushion 11 for avoiding the air pressure rod 13 will affect the comfort of the seat cushion 11. The center of gravity of the cushion 11 is closer to the center, so the resistance of the air pressure rod 13 is relatively large. In addition, the upper fixed end 131 of the air pressure rod 13 is fixed in front of the entire seat cushion 11, so the opening angle of the seat cushion 11 is relatively small. And the seat cushion 11 also can affect the smoothness when the seat cushion 11 is opened because of the large pre-pressure of the air pressure bar 13, and the merchandiseability of taking and placing articles in the glove box 12.

Another industry has developed another motorcycle seat cushion opening device 2 as shown in Figures 2 and 3. This motorcycle seat cushion opening device 2 has an upper fixing part 21, a lower fixing part 22 and an actuator 23. Between the fixing part 21 and the lower fixing part 22, a pivoting part 24 is interposed. The upper end of the actuator 23 is connected to the upper fixing part 21, and the lower end of the actuator 23 is connected to the lower fixing part 22; the upper fixing part 21 It is locked on the bottom surface of the front end of the seat cushion 11, and the lower fixing part 22 is locked on the front end of the storage box 12. By pushing the upper fixing part 21 of the actuator 23, the upper fixing part 21 is The pivoting member 24 can be used as the pivoting center point A, so that the seat cushion 11 can be opened or closed.

The above-mentioned motorcycle seat cushion opening device 2, wherein the pivot center point A of the upper fixing member 21 is set at a position higher than the lower connection point B where the lower end of the actuator 23 is connected to the lower fixing member 22, as shown in FIG. 3 , thus causing the opening angle of the seat cushion 11 to be severely restricted, thereby causing extreme inconvenience in the use of the vehicle; and the above-mentioned motorcycle seat cushion opening device 2 can only be applied to small motorcycles, causing the motorcycle seat cushion to open The versatility of device 2 is severely degraded.

Considering that the existing motorcycle seat cushion opening devices 1 and 2 have the above-mentioned deficiencies, how to provide a seat cushion 11 opening device above the storage box 12 so as to take the items in the storage box 12 is practical. It is a major issue that needs to be solved urgently.
