Description

Technical Field

[0001] The invention relates to a motorcycle compartment structure, in particular to a motorcycle compartment structure capable of slowing down the opening speed of a motorcycle seat. Background Art

[0002] With the rapid development of urbanization, motorcycles have become widely used in our daily lives. Compared to cars, motorcycles offer greater maneuverability, making them easier to navigate traffic jams and narrow spaces. Their smaller size also makes them easier to park in crowded areas. Motorcycles often have compartments for riders to store belongings while riding, or to store helmets after parking, making it easier for riders to carry items and protecting helmets and personal belongings from theft.

[0003] Typically, motorcycle compartments are opened by lifting the seat, so the seat is connected to the compartment via hinges. To save the rider the trouble of manually lifting the seat after unlocking it, many manufacturers incorporate springs to propel the unlocked seat up to its full opening. However, because the spring force must be greater than the weight of the seat, the seat's spring-up force is considerable, often startling or injuring the rider. Furthermore, the excessive force creates a reaction force when the seat is fully opened, causing it to wobble. Summary of the Invention

[0004] The main purpose of the present invention is to slow down the opening speed of a motorcycle seat cushion, thereby preventing the seat cushion from shaking or injuring the operator due to the force after it is opened.

[0005] In order to achieve the above-mentioned objectives, the present invention provides a motorcycle compartment structure, including a compartment body, a seat cushion, a fixed seat, a movable part, a torsion spring and a damping spring. The top of the compartment body has an opening, the seat cushion cover opens, the fixed seat is arranged on the compartment body, the movable part is pivotally connected to the fixed seat by a rotating shaft and has an opening stroke, and the movable part is connected to the seat cushion. The torsion spring is sleeved on the rotating shaft and respectively abuts the fixed seat and the movable part, so that the movable part flips along the opening stroke to lift the seat cushion. The damping spring pushes the movable part and the fixed seat in the opposite direction along the opening stroke, and the elastic coefficient of the damping spring is smaller than the elastic coefficient of the torsion spring.

[0006] Optionally, a side plate extends from each side of the fixed seat, each side plate is provided with a first pivot hole, a pivot portion extends from each side of the movable part, each pivot portion is provided with a second pivot hole, and the rotating shaft can be pivotally connected to each first pivot hole and each second pivot hole.

[0007] Optionally, a fixed shaft is further included, and each of the pivoting portions is provided with a through hole on one side of the second pivot hole, and the fixed shaft passes through each of the through holes.

[0008] Optionally, the damping spring is sleeved on the fixed shaft.

[0009] Optionally, each of the side plates is provided with a stopper protruding from one side of the first pivot hole, and the stopper is used to stop the fixed shaft.

[0010] Optionally, the torsion spring has a fixed end and a force-applying end, the fixed end is attached to the fixing seat, and the force-applying end abuts against one end of the movable member.

[0011] Optionally, one end of the movable member is recessed with a limiting groove for the force-applying end to be clamped.

[0012] Optionally, the damping spring has a fixed end and a free end, the fixed end passes through and is fixed to the movable part, and the free end abuts against the fixing seat when the movable part flips to a deceleration position.

[0013] Optionally, one end of the fixing seat is recessed with a supporting groove for the free end to abut against.

[0014] Optionally, the fixing seat and the movable member are respectively provided with a plurality of fixing holes, and the fixing holes can allow a plurality of bolts to pass through to fix the fixing seat and the movable member to the compartment body and the seat cushion respectively.

[0015] The present invention also has the following benefits: By utilizing the fixed shaft of the movable member and the stopper of the fixed seat, when the movable member rotates to the stop position, the fixed shaft is stopped by the stopper, preventing the movable member from further rotating. The movable member's retaining groove prevents the torsion spring from swaying, while the damping spring, which penetrates and secures the movable member, prevents swaying. Adjusting the angle of the damping spring's free end can alter the point at which the damping spring begins to act on the fixed seat, thereby adjusting the duration of the free end's force application to the abutment groove.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] The present invention provides a motorcycle compartment structure, please refer to Figures 1 to 3 As shown, it mainly includes a body 10, a seat cushion 20, a fixed seat 30, a movable part 40, a torsion spring 50 and a damping spring 60.

[0030] Please see first Figure 10 As shown, the body 10 has a payload space 11 for riders to place items, and a long, rectangular opening 12 is formed at the top of the body 10. A seat cushion 20 is generally elongated, corresponding to the shape of the opening 12, and covers the opening 12. In this embodiment, the seat cushion 20 is secured by a latch (not shown) located at one end of the body 10, ensuring that the seat cushion 20 remains covered over the opening 12 and cannot be opened. However, the present invention is not limited to this method of locking the seat cushion 20.

[0031] The fixing base 30 is disposed within the payload space 11 of the body 10, at the end of the body 10 opposite the latch (not shown). The fixing base 30 is generally plate-shaped and has a plurality of fixing holes 31 extending therethrough for bolts (not shown) to pass through and secure the fixing base 30 within the body 10. However, the present invention is not limited thereto; for example, the fixing base 30 may also be secured to the body 10 by welding. Further, a side plate 32 extends from each left and right side of the fixing base 30, and each side plate 32 defines a first pivot hole 321. An abutment groove 33 is also recessed and formed at one end of the fixing base 30 between the two side plates 32.

[0032] The movable member 40 is generally plate-shaped and is pivotally connected to the fixed base 30 by a rotating shaft 41 and has an opening stroke. In this embodiment, the opening stroke of the movable member 40 starts from a starting position S and moves to a stop position X as the end point, and there is also a deceleration position Y between the starting position S and the stop position X in the opening stroke. Specifically, one end of the movable member 40 extends to a pivot portion 40A on the left and right sides respectively. Each pivot portion 40A is respectively provided with a second pivot hole 411 and a through hole 412, and the second pivot hole 411 is located on the outside of the through hole 412. The two ends of the rotating shaft 41 pass through the first pivot hole 321 and the second pivot hole 411, so that the pivot portion 40A of the movable member 40 can be pivotally connected to the outside of the side plate 32 of the fixed base 30.

[0033] To further illustrate, the movable member 40 is also provided with a plurality of fixing holes 42 for a plurality of bolts (not shown) to pass through and connect the movable member 40 to the seat cushion 20, so that when the movable member 40 is flipped relative to the fixed base 30, it can drive the seat cushion 20 to open. In addition, the through holes 412 of the two pivotal parts 40A are provided for a fixed shaft 43 to pass through and be fixed. The two side plates 32 of the fixed base 30 extend on one side of the first pivot hole 321 and are provided with a stopper 322. In this way, when the movable member 40 is flipped to the stop position X of the opening stroke with the rotating shaft 41 as the axis, the fixed shaft 43 will abut against the stopper 322 and prevent the movable member 40 from continuing to flip. Figure 8 and Figure 9 Preferably, the designer can adjust the position of the stop block 322 and adjust the stop position X according to different needs, and the present invention is not limited thereto.

[0034] The torsion spring 50 is mounted on the rotating shaft 41 and abuts against the fixed seat 30 and the movable part 40 respectively, so that the movable part 40 can flip along the opening stroke to lift the seat cushion 20. Specifically, the torsion spring 50 has at least one fixed end 51 and one force-applying end 52, but the torsion spring 50 described in this embodiment has two fixed ends 51 and one force-applying end 52. The two fixed ends 51 of the torsion spring 50 are respectively attached and fixed to the fixed seat 30. The force-applying end 52 of the torsion spring 50 abuts against one end of the movable part 40 and continuously applies force to the movable part 40 along the opening stroke. In this way, when the lock of the car body 10 (not shown) releases the lock on the seat cushion 20, the movable part 40 can be flipped by the torsion spring 50 to open the seat cushion 20 along the opening stroke. Preferably, a limiting groove 44 is recessed at one end of the movable member 40 for the force-applying end 52 to abut against, and the force-applying end 52 of the torsion spring 50 is clamped in the limiting groove 44 , so that the torsion spring 50 sleeved on the rotating shaft 41 will not move left or right.

[0035] The damping spring 60 is mounted on the fixed shaft 43 and pushes against the movable member 40 and the fixed seat 30 in the opposite direction along the opening stroke. The elastic coefficient of the damping spring 60 is smaller than that of the torsion spring 50. Thus, the reverse action of the damping spring 60 can slow the opening speed of the seat cushion 20. Specifically, the damping spring 60 has at least one fixed end 61 and one free end 62. However, the damping spring 60 described in this embodiment has two fixed ends 61 and one free end 62. The two fixed ends 61 of the damping spring 60 are respectively inserted through and fixed to the movable member 40, thereby preventing the damping spring 60 mounted on the fixed shaft 43 from moving left or right. The free end 62 of the damping spring 60 only contacts the abutment groove 33 of the fixed seat 30 when the movable member 40 flips to the deceleration position Y, and begins to apply force to the fixed seat 30 in the opposite direction along the opening stroke to slow the opening speed of the seat cushion 20. Preferably, the designer can adjust the angle of the free end 62 to change the time point when the damping spring 60 starts to act on the fixed seat 30 (i.e., adjust the position of the deceleration position Y in the opening stroke) according to different needs, thereby increasing or decreasing the time that the free end 62 applies force to the abutment groove 33.

[0036] See also Figures 3 to 5 FIG2 shows a schematic diagram of the motorcycle compartment structure of the present invention, with the seat cushion 20 unlocked and in the starting position S. The seat cushion 20 is locked to the compartment body 10 by a latch (not shown). At this point, the force-applying end 52 of the torsion spring 50 abuts against the retaining groove 44 of the movable member 40 and continues to apply force to the movable member 40. The free end 62 of the damping spring 60 is suspended in the air, so the damping spring 60 has not yet begun to apply a reaction force to the movable member 40 and the fixed seat 30.

[0037] Please see next Figure 6 and Figure 7As shown, a schematic diagram of the motorcycle compartment structure of the seat cushion 20 of the present invention reaches the deceleration position Y when opening. Since the seat cushion 20 is locked by the lock buckle (not shown), the force-applying end 52 of the torsion spring 50 can push the movable part 40 to flip along the opening stroke, and drive the seat cushion 20 to flip to the deceleration position Y. At this time, the force-applying end 52 of the torsion spring 50 is still against the limiting groove 44 of the movable part 40 and continues to apply force to the movable part 40. The free end 62 of the damping spring 60 just flips to contact the abutting groove 33 of the fixed seat 30, so at this time the damping spring 60 begins to apply a reaction force to the movable part 40 and the fixed seat 30, thereby slowing down the flipping speed of the seat cushion 20 until the seat cushion 20 flips to the stop position X.

[0038] Please see next Figures 8 to 10 FIG. 1 is a schematic diagram of the structure of a motorcycle compartment in which the seat cushion 20 of the present invention reaches the stop position X when fully opened. Because the movable member 40 is subjected to the reaction force exerted by the damping spring 60, the flipping speed of the seat cushion 20 when opening is slowed down, so that the seat cushion 20 reaches the stop position X at a slower speed without rebounding or shaking. At this time, the force-applying end 52 of the torsion spring 50 still abuts against the limiting groove 44 of the movable member 40 and continues to apply force to the movable member 40. The free end 62 of the damping spring 60 also still abuts against the abutting groove 33 of the fixed seat 30 and continues to apply force in the opposite direction to the movable member 40. The fixed shaft 43 of the movable member 40 is stopped by the stop block 322 of the fixed seat 30, preventing the movable member 40 from further flipping.
