Description

Technical Field

[0001] The utility model belongs to the technical field of two-wheeled vehicles and relates to a connection structure of a vehicle seat cushion. Background Art

[0002] In the prior art, two-wheeled vehicles such as motorcycles and electric vehicles usually use storage boxes to accommodate larger items such as helmets, and the seat cushion on the storage box can be easily opened and closed by using a hinge arranged at the front end of the storage box. For example, the improved structure of the motorcycle storage box device described in Chinese Patent No.: "200920295855.6" has a specific structure as follows: it includes a storage box below the motorcycle seat cushion, a fuel tank behind the storage box, the storage box and the fuel tank are both fixed to the frame, and a fuel tank cover fixed to the frame is arranged above the fuel tank; the seat cushion and the storage box are connected by a hinge, and after the seat cushion lock is opened, the seat cushion is opened upward with the hinge as the center and the bottom surface of the seat cushion as the interface, so that a helmet can be put into or taken out of the storage box. In the above structure, when the seat cushion rotates relative to the storage box and the frame to open, a space needs to be provided on the frame for the seat cushion to rotate outward. It can also be seen from the drawings of the patent that the edge of the frame is concave relative to the seat cushion to prevent the seat cushion from rotating and interfering with the frame. However, the space on the frame greatly reduces the beauty of the vehicle. At the same time, the inward retraction of the frame also reduces the size of the storage box built into the frame, and the storage space is reduced. Summary of the invention

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1-3 As shown, the connection structure of the seat cushion of the vehicle comprises two groups of connecting rods 3 connecting the vehicle frame 1 and the seat cushion bottom plate 2, and the connecting rods 3 comprise a first connecting rod 31, a second connecting rod 32, a third connecting rod 33 and a fourth connecting rod 34. The ends of the first connecting rod 31 and the third connecting rod 33 are hinged on the vehicle frame 1, and the ends of the second connecting rod 32 and the fourth connecting rod 34 are hinged on the seat cushion bottom plate 2. The end of the second connecting rod 32 is hinged to the end of the first connecting rod 31, and the end of the third connecting rod 33 is hinged to the end of the fourth connecting rod 34. The first connecting rod 31 is hinged to the fourth connecting rod 34, and the hinge point between the first connecting rod 31 and the fourth connecting rod 34 is arranged close to the hinge point between the first connecting rod 31 and the second connecting rod 32. The length of the second connecting rod 32 is the same as the length of the third connecting rod 33, the length of the first connecting rod 31 is the same as the length of the fourth connecting rod 34, and the length of the first connecting rod 31 is greater than the length of the second connecting rod 32.

[0018] The above technical solution also includes a first mounting plate 4 mounted on the frame 1 and a second mounting plate 5 mounted on the seat bottom plate 2. The first mounting plate 4 is provided with protruding first connecting portions 41 on both sides, and the second mounting plate 5 is provided with protruding second connecting portions 51 on both sides. The first mounting plate 4 and the second mounting plate 5 are both approximately U-shaped. The ends of the first connecting rod 31 and the third connecting rod 33 are hinged on the first connecting portion 41, and the ends of the second connecting rod 32 and the fourth connecting rod 34 are hinged on the second connecting portion 51.

[0019] When the seat bottom plate 2 is closed, Figure 3As shown, the second mounting plate 5 is located above the first mounting plate 4, and the first connecting rod 31 and the fourth connecting rod 34 are close to each other, so that the connecting rod 3 is in a compressed and overlapped state. Figure 1 , 2 As shown, the first connecting rod 31 and the third connecting rod 33 gradually rotate upwards. The first connecting rod 31 and the third connecting rod 33 make the seat cushion bottom plate 2 produce an upward displacement in the process of rotating and opening the seat cushion bottom plate 2, so that the seat cushion bottom plate 2 is opened upward and outwards. The first connecting rod 31 and the fourth connecting rod 34 are gradually opened, and the connecting rod 3 is in an unfolded state. The connecting rod 3 enables the seat cushion bottom plate 2 to rotate and open relative to the frame 1, and enables the seat cushion bottom plate 2 to move upward relative to the frame 1; when the seat cushion bottom plate 2 rotates outward and opens and moves upward at the same time, the seat cushion bottom plate 2 will not interfere with the frame 1, and there is no need to set a clearance space on the frame 1 for the seat cushion bottom plate 2 to rotate outward, making the frame 1 more beautiful as a whole, and the size of the storage box in the frame 1 is also larger, and the storage space is larger. At the same time, the connecting rod 3 has a simple structure, is easy to install, and has stable and reliable transmission.

[0020] In the above technical solution, a mounting hole 42 is formed on the first mounting plate 4, and the mounting hole 42 is in an elongated strip shape, and the rod of the screw passes through the mounting hole 42 and is mounted on the frame 1. The elongated mounting hole 42 enables the first mounting plate 4 to be mounted on the frame 1, and the mounting position can be adjusted relative to the frame 1.

[0021] In the above technical solution: it includes a plurality of first hinge blocks 6 and a plurality of second hinge blocks 7, and the first hinge block 6 and the second hinge block 7 both include a hinge shaft and positioning blocks at both ends of the hinge shaft, and the positioning blocks are detachably connected to the hinge shaft by threaded connection or direct insertion interference fit, so as to facilitate installation and disassembly. The diameter of the first hinge block 6 is larger than the diameter of the second hinge block 7. The first hinge block 6 is used for hinge connection between the first connecting rod 31 and the first connecting part 41, between the fourth connecting rod 34 and the second connecting part 51, and between the first connecting rod 31 and the fourth connecting rod 34, and at the same time, the parts on the first connecting rod 31 and the fourth connecting rod 34 for installing the first hinge block 6 are widened. The first hinge block 6 has a larger diameter and higher strength, so that the hinge connection between the first connecting rod 31 and the first connecting part 41, between the fourth connecting rod 34 and the second connecting part 51, and between the first connecting rod 31 and the fourth connecting rod 34 is more stable and reliable. The second connecting rod 32 and the second connecting portion 51 , the second connecting rod 32 and the first connecting rod 31 , the fourth connecting rod 34 and the third connecting rod 33 , and the third connecting rod 33 and the first connecting portion 41 are all hinged by the second hinge block 7 .
