Detailed Description

The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.

The present invention provides a carriage structure of a motorcycle, as shown in fig. 1 to 3, which mainly comprises a carriage 10, a seat 20, a fixed seat 30, a movable member 40, a torsion spring 50 and a damping spring 60.

Referring to fig. 10, the compartment 10 has a loading space 11 for the rider to place articles, and an elongated opening 12 is formed at the top of the compartment 10. The seat cushion 20 is generally elongated corresponding to the shape of the opening 12 and covers the opening 12. In the embodiment, the seat cushion 20 is locked by a lock (not shown) at one end of the compartment 10, so that the seat cushion 20 can keep covering the opening 12 and cannot be opened, but the utility model is not limited thereto.

The fixing base 30 is disposed in the payload space 11 of the car 10 and is located at the other end of the car 10 opposite to the latch (not shown). The fixing base 30 is generally plate-shaped and has a plurality of fixing holes 31 for bolts (not shown) to pass through to fix the fixing base 30 in the compartment 10, but the utility model is not limited thereto, for example, the fixing base 30 may be fixed in the compartment 10 by welding. Further, a side plate 32 extends from the left side and the right side of the fixing base 30, a first pivot hole 321 is formed in each side plate 32, and an abutting groove 33 is further formed at one end of the fixing base 30 between the two side plates 32.

The movable member 40 is substantially plate-shaped and pivotally connected to the fixed base 30 by a rotating shaft 41 to have an opening stroke. In the present embodiment, the opening stroke movable element 40 has a moving stroke formed by a starting position S as a starting point and a stopping position X as an end point, and a decelerating position Y is further provided between the starting position S and the stopping position X in the opening stroke. Specifically, one end of the movable member 40 extends to form a pivot portion 40A on each of the left and right sides. Each pivot portion 40A is formed with a second pivot hole 411 and a through hole 412, and the second pivot hole 411 is located outside 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 element 40 can be pivoted to the outer side of the side plate 32 of the fixed base 30.

Further, the movable member 40 further has a plurality of fixing holes 42 for a plurality of bolts (not shown) to pass through to connect the movable member 40 to the seat cushion 20, so that the movable member 40 can drive the seat cushion 20 to open when turning over relative to the fixing base 30. In addition, the through hole 412 of the two pivoting portions 40A is used for a fixing shaft 43 to penetrate and fix, and the two side plates 32 of the fixing base 30 are provided with a stop 322 extending and protruding from one side of the first pivoting hole 321. Therefore, when the movable member 40 rotates around the rotating shaft 41 to the stop position X of the opening stroke, the fixed shaft 43 abuts against the stop 322, so that the movable member 40 cannot rotate further, as shown in fig. 8 and 9. Preferably, the designer can adjust the stop position X by adjusting the position of the stop block 322 according to different requirements, which is not limited by the utility model.

The torsion spring 50 is sleeved on the rotating shaft 41 and abuts against the fixed seat 30 and the movable member 40, so that the movable member 40 can be turned over 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 has two fixed ends 51 and one force-applying end 52 in the embodiment. Two fixed ends 51 of the torsion spring 50 are respectively attached to and clamped in the fixing base 30. The force application end 52 of the torsion spring 50 abuts against one end of the movable member 40 and continuously applies force to the movable member 40 along the opening stroke. When the lock catch (not shown) of the compartment 10 releases the lock on the seat cushion 20, the movable member 40 can be turned over by the torsion spring 50 to open the seat cushion 20 along the opening stroke. Preferably, a limit groove 44 is concavely disposed at an end of the movable member 40, which is abutted to the force application end 52, and the force application end 52 of the torsion spring 50 is clamped in the limit groove 44, so that the torsion spring 50 sleeved on the rotating shaft 41 cannot move left and right.

The damping spring 60 is sleeved on the fixed shaft 43 and pushes against the movable member 40 and the fixed seat 30 along the opening stroke in the opposite direction. And the elastic coefficient of the damping spring 60 is smaller than that of the torsion spring 50, whereby the opening speed of the seat cushion 20 can be slowed down by the reverse action of the damping spring 60. Specifically, the damping spring 60 has at least a fixed end 61 and a free end 62, but the damping spring 60 has two fixed ends 61 and a free end 62 in the embodiment. Two fixed ends 61 of the damping spring 60 are respectively inserted and fastened to the movable member 40, so that the damping spring 60 sleeved on the fixed shaft 43 cannot move left and right. The free end 62 of the damping spring 60 abuts against the abutting groove 33 of the fixed seat 30 when the movable element 40 is turned to the deceleration position Y, and applies a force to the fixed seat 30 in the opposite direction along the opening stroke to slow down the opening speed of the seat cushion 20. Preferably, the designer can adjust the angle of the free end 62 according to different requirements 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), so as to increase or decrease the force application time of the free end 62 against the abutting groove 33.

Referring to fig. 3 to 5, the structure of the motorcycle compartment at the starting position S when the seat cushion 20 is not unlocked is shown schematically. The seat cushion 20 is locked and fixed to the car 10 by a lock catch (not shown). At this time, the force application end 52 of the torsion spring 50 abuts against the stopper groove 44 of the movable member 40 and continuously applies force to the movable member 40. The free end 62 of the damping spring 60 is in a floating state, so the damping spring 60 does not yet exert a counter force on the movable element 40 and the fixed base 30.

Referring to fig. 6 and 7, the seat 20 of the present invention reaches the deceleration position Y when opened. Since the seat cushion 20 is unlocked from the lock (not shown), the force applying end 52 of the torsion spring 50 can push the movable member 40 to flip along the opening stroke, and the seat cushion 20 is driven to flip to the deceleration position Y. At this time, the force application end 52 of the torsion spring 50 still abuts against the limiting groove 44 of the movable member 40 and continuously applies force to the movable member 40. The free end 62 of the damping spring 60 just turns over to contact with the abutting groove 33 of the fixed seat 30, so the damping spring 60 starts to apply a counter force to the movable member 40 and the fixed seat 30 at this time, and the turning speed of the opening of the seat cushion 20 can be slowed down until the seat cushion 20 turns over to the stop position X.

Referring to fig. 8 to 10, the seat cushion 20 of the present invention reaches the stop position X when fully opened. The movable member 40 is capable of slowing the turning speed of the opening of the seat cushion 20 due to the reaction force applied by the damping spring 60, so that the seat cushion 20 reaches the stop position X at a slow speed without bouncing or shaking. At this time, the force application end 52 of the torsion spring 50 still abuts against the limiting groove 44 of the movable member 40 and continuously applies force to the movable member 40. The free end 62 of the damping spring 60 still abuts against the abutting groove 33 of the fixed seat 30 and continuously applies a reverse force to the movable member 40, and the fixed shaft 43 of the movable member 40 is stopped by the stopper 322 of the fixed seat 30, so that the movable member 40 cannot turn over any more.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the utility model is all within the protection scope of the utility model. The protection scope of the utility model is subject to the claims.
