Description

Technical Field

[0001] This utility model relates to the field of scooter technology, specifically a scooter folding mechanism. Background Technology

[0002] Scooters are a common mode of transportation. To improve storage convenience, many scooters on the market adopt a foldable design. However, after folding the scooter, users need to lift it and place it in a suitable storage location. The locking mechanism at the folding point of existing scooters is too simple when the scooter is unfolded, resulting in poor stability and security. During use, the locking mechanism can easily unlock, causing the scooter to fold again, potentially leading to injury or damage to the user and the scooter itself. Utility Model Content

[0003] The purpose of this invention is to provide a scooter folding mechanism to solve the problems mentioned in the background art.

[0006] The connecting part is provided with a locking structure and a locking hook structure. The locking structure and the locking hook structure cooperate with each other to provide two locking mechanisms on the connecting part, thereby improving the stability and security of the connecting part.

[0007] By adopting the above technical solution, the front wheel of the scooter is locked in a locked state through the cooperation between the locking hook structure on the connecting part. The locking hook structure limits the locking structure, preventing the locking structure on the connecting part from coming off when the user is using the scooter, thus improving the stability and safety of the scooter.

[0008] Preferably, the connecting part includes a head tube and a base, the head tube and the base are rotatably connected by a base shaft, and bolts are respectively provided on both sides of the base, and a first vehicle body connector and a second vehicle body connector are respectively installed by the bolts.

[0009] By adopting the above technical solution, the connecting part is connected to the front wheel and the load-bearing part of the scooter through the head tube, the first vehicle body connecting part and the second vehicle body connecting part, respectively.

[0011] By adopting the above technical solution, the distance between the first folding locking sleeve and the second folding locking sleeve is kept greater than the distance between the outer end faces of the base limiting slot. The head tube rotates downward through the base shaft until the quick release rod assembly is embedded into the bottom along the arc-shaped guide groove of the base (the locking hook can be automatically or manually lifted upward). The quick release rod assembly is operated until the first folding locking sleeve and the second folding locking sleeve are embedded in the base limiting slot and the quick release rod assembly is locked, thus achieving the purpose of initial locking of the connection part.

[0012] Preferably, the locking hook structure on the connecting part includes a locking hook limiting pin and a locking hook mounting post. The locking hook limiting pin is installed on the side of the base near the first vehicle body connecting member, and the locking hook mounting post is installed on the side of the first vehicle body connecting member away from the second vehicle body connecting member. The first vehicle body connecting member is equipped with a locking hook and an elastic member through the locking hook mounting post.

[0013] By adopting the above technical solution, the locking hook is in a horizontal state with the assistance of the elastic element and the locking hook limiting pin. When the locking structure is locked, the locking hook is lifted and hooks the second folding locking sleeve, so as to achieve the purpose of secondary locking of the connection part, and further improve the stability and safety of the connection part.

[0014] Preferably, the top of the head tube has a fork component mounting hole, and the head tube is rotatably connected to the fork component on the front wheel through the fork component mounting hole.

[0019] By adopting the above technical solution, the round rod on the quick-release rod assembly overlaps with the base through the arc-shaped guide groove, and the first folding locking sleeve and the second folding locking sleeve are engaged through the limiting groove hole.

[0020] Preferably, a fixing hole is provided at the bottom of one side of the base near the end of the first vehicle body connector, and the base is connected to the locking hook limiting pin through the fixing hole.

[0021] By adopting the above technical solution, the locking hook limiting pin is stably and securely installed on the base through the fixing hole, and the locking hook limiting pin can be prevented from falling off the base.

[0022] Preferably, the base, the first vehicle body connector, and the second vehicle body connector are all provided with connection holes on one side, and the dimensions of the bolts and locking hook mounting posts are adapted to the dimensions of the connection holes.

[0023] By adopting the above technical solution, the first vehicle body connector and the second vehicle body connector are stably and securely installed on the base through connecting holes and bolts, preventing the first vehicle body connector and the second vehicle body connector from falling off the base.

[0024] Preferably, the first vehicle body connector and the second vehicle body connector are provided with mounting holes.

[0025] By adopting the above technical solution, the load-bearing components of the scooter are stably connected through the mounting holes on the first and second body connectors.

[0026] Compared with the prior art, the beneficial effects of this utility model are: the scooter folding mechanism has a locking hook structure on the connecting part. When the scooter is in the locked state, the locking structure is hooked by the locking hook structure. Furthermore, the locking hook structure is provided with an elastic element to prevent the locking hook structure from disengaging. This avoids the locking structure from unlocking during user use, improves the safety and stability of the scooter, and prevents user injury and damage to the scooter. Attached Figure Description

[0045] Working principle: When the user folds and locks the scooter, the distance between the first folding locking sleeve 23 and the second folding locking sleeve 25 is greater than the distance between the outer end faces of the base limiting slot. The head tube 20 rotates downward through the base shaft 26 until the quick-release lever assembly 24 is embedded in the bottom along the arc-shaped guide groove of the base. The locking hook can be automatically or manually lifted upward. Operate the quick-release lever assembly 24 until the first folding locking sleeve 23 and the second folding locking sleeve 25 are embedded in the base limiting slot and the quick-release lever assembly 24 is locked, achieving the purpose of locking the connector. When the user folds and opens the scooter, in the folded and locked state, release the quick-release lever assembly 24 until the first folding locking sleeve 23 and the second folding locking sleeve 25 are completely removed from the base limiting slot. Then, manually press the end of the locking hook near the vehicle body connector. The grooved end of the locking hook 212 is lifted upward, allowing the scooter to be folded and opened.
