Description

Technical Field

[0001] The utility model relates to the technical field of scooter accessories, in particular to a scooter seat connecting device. Background Art

[0002] A scooter is a means of transportation, and some scooters are equipped with seats. In order to facilitate people to carry, some scooter manufacturers have developed scooters with foldable handlebars or seats. The existing folding seat structure can refer to the Chinese patent with announcement number CN206749978U, which discloses a seat rod folding device, the device includes a base, a seat rod that can be flipped to be close to the base or flipped to a vertical state is provided on the base, a fixing frame is convexly provided on the base, a connecting shaft is passed through the fixing frame, a wing plate is convexly provided on the seat rod, a limiting hole is opened on the wing plate, which is aligned with the connecting shaft when the seat rod is flipped to a vertical state and can accommodate the connecting shaft to be inserted into the limiting hole, a latch is radially inserted on the connecting shaft, and a spring with two ends located between the fixing frame and the latch is sleeved on the connecting shaft, the spring can drive the latch to drive the connecting shaft to elastically insert into the limiting hole to prevent the connecting shaft from detaching.

[0003] In the above scheme, when the seat rod is flipped to a vertical state, the limiting hole is in a state of being aligned with the connecting shaft, and the connecting shaft is driven by the spring to be inserted into the limiting hole, which can effectively limit the flipping of the seat rod. In the above matching relationship, there are very high requirements for the coaxiality size of the connecting shaft and the limiting hole and the diameter size of the connecting shaft and the limiting hole. The precision requirements for parts are high during production. If there is a deviation in the coaxiality or the diameter of the limiting hole is too small, the connecting shaft will not be able to be inserted into the limiting hole. At this time, the processing difficulty can be reduced by increasing the diameter of the limiting hole. However, this will cause a gap when the connecting shaft is inserted into the limiting hole. Then the seat will feel shaking when in use, affecting the user experience of the scooter. Therefore, in order to reduce the processing difficulty during production, the seat rod folding device will inevitably lead to a worse user experience. Utility Model Content

[0004] In view of the disadvantage that the existing seat rod folding device inevitably leads to a worse user experience in order to reduce the difficulty of processing, the purpose of the utility model is to provide a scooter seat connecting device that can reduce the shaking feeling of the seat to improve the seat usage experience.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A scooter seat connection device comprises a base and a support frame flipped on the base, a limit piece elastically telescopically arranged on the base, a first limit structure for inserting the limit piece is arranged on the support frame, a locking assembly capable of driving the support frame and the limit piece to closely cooperate is arranged between the support frame and the limit piece, the locking assembly is movably arranged relative to the support frame, a locking position for the locking assembly to movably enter or disengage is opened on the support frame, and a hanging mechanism for hanging objects is arranged on the support frame.

[0007] By adopting the above scheme, the locking assembly can drive the support frame and the limit piece to fit closely after entering the locking position, which can reduce the fitting gap between the limit piece and the limit structure. This also allows the processing accuracy of the product to be appropriately adjusted. Even if there is a gap, it can be offset with the help of the locking assembly. At the same time, it can also reduce the shaking feeling generated during the use of the seat and improve the product's user experience.

[0008] Preferably, a pressure plate is provided on the support frame, the locking position includes an open groove opened on the pressure plate, and the locking assembly is provided on the limiting member and can move into or out of the open groove as the limiting member is extended or rotated.

[0009] Preferably, the locking assembly includes a pull rod inserted on the limiting member, a clamping plate sleeved on the pull rod, and a driving structure that drives the clamping plate to approach the limiting member and press the pressure plate when the pull rod enters the open groove.

[0010] Preferably, the driving structure comprises a cam handle arranged at the end of the pull rod, and when the cam handle rotates, the cam portion thereof drives the pressing sheet to press the pressing plate.

[0011] By adopting the above scheme, the cam handle moves with the movement of the limit member. Conversely, the limit member can be controlled by operating the cam handle. The user can clearly know the matching status of the limit member and the support frame through the position of the cam handle. In the prior art, the part that has the same function as the limit member is the connecting shaft, and its position is blocked by the external fixing frame and wing plate and is difficult to observe directly. Therefore, the cam handle in this scheme reduces the difficulty of locking the support frame, and can also play the role of locking the support frame, which is very convenient to use.

[0012] Preferably, a mounting seat is provided on the base, the limiting member includes a pin shaft that is telescopically extended on the mounting seat, an elastic member that drives the pin shaft to elastically extend and retract is provided between the mounting seat and the pin shaft, a wing plate is provided on the support frame, the first limiting structure includes a limiting hole opened on the wing plate and aligned with the pin shaft when the support frame is in a vertical state, and the wing plate is also provided with an introduction structure that facilitates the cooperation between the pin shaft and the limiting hole.

[0013] Preferably, the introduction structure includes an introduction section extending from the end of the pin shaft and having a diameter smaller than the pin shaft, and a cutout is provided on the wing plate for the introduction section to enter the limiting hole from outside the wing plate, and the width of the cutout is greater than or equal to the diameter of the introduction section and smaller than the diameter of the pin shaft.

[0014] By adopting the above scheme, when the support frame gradually flips to a vertical state, the limit member is pressed to retract it. At this time, the introduction section is opposite to the incision of the support frame. When the introduction section enters the limit hole from the incision, the limit member is released, and the elastic member drives the limit member to pop out and plug into the limit hole.

[0015] Preferably, the suspension mechanism includes a suspension rotatably mounted on a support frame, the suspension is provided with a groove, the opening of the groove faces upward when the suspension is unfolded, and a second limiting structure is provided between the support frame and the suspension to limit the suspension from flipping when the suspension is unfolded.

[0016] By adopting the above scheme, the suspension mechanism can be used to hang daily items such as umbrellas, water cups or shopping bags when the scooter is traveling, thereby increasing the use function of the scooter seat. The suspension can be unfolded or folded, and after folding, it fits with the support frame to reduce the volume and maintain the aesthetics.

[0017] Preferably, the second limiting structure includes a limiting pin protruding from the side wall of the support frame, the limiting pin is located on the path of the suspension flipping, and the suspension is provided with a limiting groove for the limiting pin to abut.

[0018] The utility model adopts the above technical scheme, which has significant technical effects: after entering the locking position, the locking assembly can drive the support frame to cooperate closely with the limiting member, which can reduce the matching gap between the limiting member and the limiting structure, which also makes it possible to appropriately adjust the processing accuracy of the product. Even if there is a gap, it can be offset by the locking assembly. At the same time, it can also reduce the shaking feeling generated during the use of the seat, thereby improving the use experience of the product; the suspension mechanism can be used to hang daily items such as umbrellas, water cups or shopping bags when the scooter is driving, thereby increasing the use function of the scooter seat.
