Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a folding seat of box behind tricycle, as shown in fig. 1 and 2, including setting up riser 11 on the box boxboard 1 of back box, riser 11 can set up on each boxboard 1 of back box, the optimum setting is on the boxboard 1 that is close to driver one side, logical groove 12 has been seted up on riser 11, it distributes along the length direction of riser 11 to lead to groove 12, riser 11 articulates on the lower extreme cell wall that leads to groove 12 has seat 121, as shown in fig. 3, connect through air spring 122 between seat 121 and the logical groove 12 upper end cell wall, air spring 122's both ends are equallyd divide and are articulated with seat 121 and logical groove 12 upper end cell wall respectively, when seat 121 rotates to horizontal position, air spring 122 stroke is to the biggest. When the seat plate 121 rotates into the through slot 12, the pulling force of the gas spring 122 on the seat plate 121 will fix the seat plate 121 in the through slot 12.

As shown in fig. 1 and 2, when a user needs to sit in the rear box, the user rotates the seat plate 121 in the horizontal direction, the stroke of the gas spring 122 is gradually increased until the seat plate 121 rotates to the horizontal position, the stroke of the gas spring 122 reaches the maximum at the moment, a pulling force is provided for the seat plate 121, the purpose of facilitating sitting of the user and reducing potential safety hazards is achieved, when the seat plate 121 does not need to be used, the seat plate 121 rotates upwards, and the seat plate 121 returns to the through groove 12 under the action of the gas spring 122.

As shown in fig. 1 and 2, when the seat plate 121 rotates to the horizontal position, the vertical plate 11 is provided with a limiting member for limiting the seat plate 121 to rotate downwards. The setting of locating part has further restricted riser 11 in the horizontal position, the stability of being convenient for the passenger to take.

As shown in fig. 1 and fig. 2, the limiting member includes a first sliding groove 13 disposed on a side surface of the seat plate 121, a second sliding groove 131 is disposed on the vertical plate 11, the first sliding groove 13 and the second sliding groove 131 are located on the same straight line, sliding blocks 132 are connected in the first sliding groove 13 and the second sliding groove 131 in a sliding manner, the two sliding blocks 132 are connected through a connecting rod 133, two ends of the connecting rod 133 are hinged to the sliding blocks 132, when the seat plate 121 rotates to a horizontal position, the first sliding groove 13 faces downward, and the sliding blocks 132 in the second sliding groove 131 abut against a lower end groove wall of the second sliding groove 131. At this time, the second sliding chute 131 limits the movement of the sliding block 132 in the second sliding chute 131, so as to fix the position of one end of the connecting rod 133, the sliding block 132 in the first sliding chute 13 also moves to the groove wall of one end of the first sliding chute 13 far away from the second sliding chute 131, and at this time, the connecting rod 133 provides a supporting force for the seat plate 121, so that the seat plate 121 provides a stable supporting force for the rider. When the seat board 121 rotates towards the through slot 12, the sliding block 132 in the second sliding slot 131 moves towards the first sliding slot 13, the sliding block 132 in the first sliding slot 13 moves towards the second sliding slot 131, and the connecting rod 133 gradually rotates towards the vertical direction, so that the influence on the space of the rear box body when the seat board 121 is folded is reduced. Or the limiting member is a clamping block arranged on the vertical plate 11, and the clamping block is located at the lower end of the seat plate 121, so that when the seat plate 121 rotates to the horizontal position, the clamping block abuts against the lower end surface of the seat plate 121.

As in fig. 1 and 2, riser 11 upper end is connected with a plurality of pin 14 through the pivot rotation, when seat 121 rotates to horizontal position, pin 14 rotates to the position with riser 11 vertically, be convenient for spacing to the passenger, increase the security that the passenger took, when pin 14 rotates to the position with riser 11 vertically, be equipped with restriction pin 14 pivoted mounting on the riser 11, when need not take, rotate pin 14 to riser 11 side orthographic projection face in, reduce the influence of pin 14 to the internal object transportation of back box this moment.

As shown in fig. 1 and 5, the fixing member includes a stopper 141 disposed on the vertical plate 11, when the stopper 14 rotates to a position perpendicular to the vertical plate 11, a collision block 142 abutting against the stopper 141 is disposed at a lower end of the stopper 14, at this time, the collision of the collision block 142 and the stopper 141 limits the continuous rotation of the stopper 14, when the stopper 14 rotates toward the vertical plate 11, the collision block 142 needs to be moved into the stopper 14, a slot 143 is disposed at a lower end of the stopper 14 for allowing the collision block 142 to enter the stopper 14, a compression spring 144 is disposed at a bottom of the slot 143 for allowing one end of the collision block 142 to extend out of the slot 143, when the stopper 14 rotates toward the vertical plate 11, an inclined surface 145 is disposed on the collision block 142 for allowing the collision block 142 to enter the slot 143, and as the stopper 14 continues to move toward the vertical plate 11, the inclined surface 145 and a side edge of the vertical plate 11, the inclined surface 145 enables the collision block 142 to gradually move toward the slot 143, until the contact block 142 enters the placing groove 143, the compression spring 144 is compressed to have elastic restoring force, when the passenger rotates the stop lever 14 to a position perpendicular to the vertical plate 11, the compression spring 144 ejects the contact block 142 from the placing groove 143, so that the contact block 142 is abutted against the stopper 141, and the stop lever 14 is limited.

As shown in fig. 1 and 2, the stopper 141 is detachably connected to the vertical plate 11, so that the stopper 141 can be replaced or the position of the stopper 141 can be changed, and the rotation angle of the blocking rod 14 can be changed, thereby meeting different requirements of different passengers.

As shown in fig. 1 and 2, a connecting plate 15 is disposed at a position where the stopper 141 is connected to the vertical plate 11, a moving groove 151 for horizontal movement of the connecting plate 15 is disposed on the vertical plate 11, a limiting rod 152 abutting against a groove bottom of the moving groove 151 is connected to the connecting plate 15 by a thread, and the position of the stopper 141 can be changed by changing the position of the connecting plate 15 in the moving groove 151.

As shown in fig. 3 and 4, when the blocking rod 14 rotates to the upper end of the vertical plate 11, one side of the blocking rod 14 is provided with a magnet 16 extending to the vertical plate 11, and the vertical plate 11 is provided with an iron block 161 corresponding to the magnet 16. The magnet 16 and the iron block 161 are arranged to fix the position of the blocking lever 14, so that the blocking lever 14 can be prevented from being rotated freely without passengers.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
