Definitions
- the invention relates to the field of scooters, and in particular to a novel folding scooter.
- scooters are popular among people because of their simple and convenient riding operation, small size and small space.
- Existing scooters include a body for users to stand on, a rear wheel is provided at the rear side of the bottom of the body, a steering lever is hinged at the front of the body, and a front wheel is installed at the bottom of the steering lever.
- its steering lever is perpendicular to the body, and the user can directly stand on the body to drive the scooter; when riding is not needed, the user can reversely rotate the steering lever around the hinge to close to the body to achieve folding and save space.
- Patent document CN105730590B discloses a new type of electric scooter folding structure, in which matching fastening magnets are provided at the rear of the front tube of the scooter (i.e., the steering lever, hereinafter referred to as the steering lever) and the bottom plate of the scooter (i.e., the body, hereinafter referred to as the body).
- the fastening magnets of the steering lever and the rear of the body are close to each other and magnetically attracted to each other, thereby fixing the steering lever on the body, and the user can carry the scooter by holding the steering lever.
- the existing scooters are fixed by adding fastening magnets, which has a relatively complex structure.
- the two fastening magnets suddenly separate due to insufficient magnetic force when the user holds the steering lever to carry the scooter, the body of the scooter will suddenly swing downward under its own gravity, which may easily hit the user, posing a safety hazard.
- the technical problem to be solved by the present invention is to provide a novel foldable scooter, in which the steering operating rod is not easily separated from the body in the folded state, and the scooter is relatively safe.
- the present invention provides a new type of folding scooter, wherein a rear wheel is provided at the rear of the body and a steering lever is provided at the front, a front wheel is provided at the bottom of the steering lever, the steering lever is unfolded for use, and can be retracted relative to the body when not in use to realize folding of the whole vehicle, and a dual-purpose locking member is provided, which locks the steering lever in the unfolded state to keep it in the unfolded state, and locks the steering lever in the retracted state to keep it in the retracted state.

- the dual-purpose locking member is arranged near the hinge.
- one of the steering operating lever and the vehicle body is provided with the dual-purpose locking member
- the dual-purpose locking member has a first locking portion and a second locking portion
- the other is correspondingly provided with a first locking block and a second locking block
- the specific coordination is as follows: when the steering operating lever is in an extended state, the dual-purpose locking member locks the first locking block by the first locking portion to lock the steering operating lever to maintain its extended state; when the steering operating lever is in a retracted state, the dual-purpose locking member locks the second locking block by the second locking portion to lock the steering operating lever to maintain its retracted state.
- the dual-purpose locking member is specifically arranged on the steering operating rod, and the first locking block and the second locking block are specifically arranged on the vehicle body.
- the dual-purpose locking member is a lever structure and is equipped with a torsion spring, the middle portion of which serves as a fulcrum and is connected to the steering operating rod in a manner that allows forward and reverse rotation.
- the first locking portion and the second locking portion are respectively arranged at both ends of the dual-purpose locking member, and the dual-purpose locking member and the first locking block and the second locking block are specifically matched as follows:
- the dual-purpose locking member rotates forward under the elastic force of the torsion spring to drive the first locking portion to buckle, i.e. lock the first locking block, and rotates in the reverse direction to overcome the elastic force of the torsion spring to unlock;
- the dual-purpose locking member rotates forward under the action of the torsion spring force to drive the second locking portion to buckle, i.e. lock, the second locking block, and rotates reversely to overcome the torsion spring force to unlock.
- the first locking portion is specifically located at the lower edge of the rear end of the dual-purpose locking piece
- the second locking portion is specifically located at the upper edge of the front end of the dual-purpose locking piece
- the steering operating lever is provided with a limiting slot
- the dual-purpose locking piece is provided with a shift block, which passes through the limiting slot.
- the end of the shift block is exposed outside the steering operating lever for a person to hold and shift so that the dual-purpose locking piece can overcome the elastic force of the torsion spring and rotate in the opposite direction to unlock.
- the steering lever can be retracted relative to the body to realize the folding of the whole scooter; when the steering lever is retracted, the dual-purpose locking member locks the steering lever to maintain its retracted state, preventing the steering lever from being separated from the body in the retracted state, which is safer.
- the dual-purpose locking member can not only lock the steering lever to maintain its unfolded state, but also lock the steering lever to maintain its retracted state.
- One member realizes two functions, and there is no need to add a magnetic suction member like in the prior art, and the structure is simpler.

Description
本发明涉及滑板车领域，具体涉及一种新型折叠滑板车。
滑板车作为一种便捷的代步工具，因骑行操作简单方便、小巧不占空间而深得人们喜爱。现有的滑板车，包括供使用者站立的车身，车身底部后侧设有后轮，车身前部铰接有转向操作杆，转向操作杆底部安装有前轮。滑板车在使用状态下，其转向操作杆垂直于车身，使用者可直接站立在车身上驾驶滑板车；不需要骑行时，使用者可以把转向操作杆绕铰接处反向旋转至贴近车身以实现折叠，节省空间。专利文献CN105730590B公开了一种新型的电动滑板车折叠结构，在滑板车前管(即转向操作杆，下文统称为转向操作杆)和滑板车底板(即车身，下文统称为车身)尾部设置相配的紧固磁铁，在滑板车折叠的状态下，转向操作杆的和车身尾部的紧固磁铁贴紧并相互磁吸，从而把转向操作杆固定在车身上，使用者可以通过手持转向操作杆来搬运滑板车。但是，现有的这种滑板车系通过加设紧固磁铁实现固定，结构相对复杂，并且，若在使用者手持转向操作杆搬运滑板车的过程中，两块紧固磁铁因磁力不够而突然相脱离，则车身在自身重力作用下会突然向下摆动，容易砸到使用者，存在安全隐患。

在转向操作杆展开状态下，两用锁紧件在扭簧弹力作用下正向转动带动第一锁紧部扣住即锁住第一锁紧块，克服扭簧弹力反向转动则解锁；
在转向操作杆收起状态下，两用锁紧件在扭簧弹簧力作用下正向转动带动第二锁紧部扣住即锁住第二锁紧块，克服扭簧弹力反向转动则解锁。
其中，所述第一锁紧部具体位于所述两用锁紧件后端下沿，所述第二锁紧部具体位于两用锁紧件前端上沿；在转向操作杆展开状态下，两用锁紧件具体在扭簧弹力作用下正向转动使其后端下沿的第一锁紧部往下摆动扣住第一锁紧块，克服扭簧弹力反向转动则其后端往上摆动解锁；转向操作杆具体为后仰转动收起，两用锁紧件随之转动则其前端上沿的第二锁紧部转动对准第二锁紧块，两用锁紧件在扭簧弹力作用下正向转动使其前端上沿的第二锁紧部往后摆动扣住第二锁紧块，克服扭簧弹力反向转动则其前端往前摆动解锁。
其中，所述转向操作杆开有限位通槽，所述两用锁紧件设有拨块，拨块穿过该限位通槽，拨块末端外露在转向操作杆外供人握持拨动以使两用锁紧件能够克服所述扭簧的弹力反向转动进行解锁。

以下结合具体实施方式对本发明创造作进一步详细说明。
见图1，滑板车1车身11后部设有后轮而前部设有转向操作杆12，转向操作杆12下部铰接车身11而底部设有前轮。使用者在需要使用滑板车1时，可以站立在车身11上驾驶滑板车1，驾驶过程中左右扭动转向操作杆12操控滑板车1左右转向；不使用时，使用者可朝后扳动转向操作杆12使其相对车身11后仰转动收起实现整车折叠(见图9)，节省空间。
转向操作杆12与车身11这两者的铰接处13见图2，转向操作杆12在靠近铰接处13设有两用锁紧件2，两用锁紧件2为杠杆结构，其中部作为支点23，以可正反向转动的方式前后横置安装在转向操作杆12内。见图5，两用锁紧件2后端为钩部，钩部下沿用作第一锁紧部21，而两用锁紧件2前端上沿局部凹陷形成第二锁紧部22。见图3，在车身11的靠近铰接处13相应地固定安装有居后的第一锁紧块31和居前的第二锁紧块32。见图2、图4和图5，转向操作杆12开有左右贯通的限位通槽4，限位通槽4对准安装在转向操作杆12内的两用锁紧件2的前端。两用锁紧件2朝限位通槽4伸出有拨块25；拨块25穿过并容置在该限位通槽4中，其始端连接两用锁紧件2前端而其末端251外露在转向操作杆12外。拨块25外露的末端251尺寸大于限位通槽4槽径，能够供使用者握持拨动。
见图2，为两用锁紧件2配设有扭簧24，在转向操作杆12展开状态下，两用锁紧件2在扭簧24弹力作用下绕其支点23逆时针正向转动带动其后端下沿的第一锁紧部21往下摆动至如图5所示，扣住即锁住第一锁紧块31，转向操作杆12由此被锁紧到车身11上从而保持展开状态。不使用滑板车1时，使用者可以折叠滑板车1节省空间，操作如下：
(1)解锁。
使用者握持拨块25外露的末端251(见图4)并向下按压拨动，拨块25沿限位通槽4下移带动两用锁紧件2前端一同下移，两用锁紧件2藉此克服扭簧24的弹力绕其支点23顺时针 反向转动并使其后端往上摆动，如图6所示，其后端下沿的第一锁紧部21就会离开第一锁紧块31，完成解锁，转向操作杆12不再锁紧车身11。
(2)收起。
解锁完成后，使用者可以让转向操作杆12相对车身11后仰转动收起。由于两用锁紧件2安装在转向操作杆12上，会随着转向操作杆12一同转动，为避免两用锁紧件2在转动的过程中受扭簧24弹力作用重新正向转动而碰撞到第一锁紧块31，使用者需全程保持向下按压拨块25末端251，如图7所示。转向操作杆12连同安装在其内的两用锁紧件2一同转动至收起状态时，如图8所示，两用锁紧件2前端上沿的第二锁紧部22随之转动至朝后对准第二锁紧块32。
(3)锁紧。
此时，使用者可以松开拨块25末端251，两用锁紧件2在扭簧24弹力作用下正向转动使其前端上沿的第二锁紧部22往后摆动至如图9所示，扣住即锁住第二锁紧块32，转向操作杆12由此被锁紧到车身11上从而保持收起状态。这样，使用者就可以握住转向操作杆12搬运滑板车1了。
需要使用滑板车1时，使用者需先拨动拨块25末端251使其沿限位通槽4往前移动带动两用锁紧件2克服扭簧24弹力反向转动，两用锁紧件2前端随之一同前移，其前端上沿的第二锁紧部22就离开第二锁紧块32，完成解锁，转向操作杆12不再锁紧车身11，滑板车1重新回到如图8所示的状态。然后，使用者一边保持拨动拨块25末端251一边让转向操作杆12相对车身11向前展开，直至转向操作杆12到达如图6所示的展开状态，这时，使用者再松开拨块25末端251，两用锁紧件2便在扭簧24弹力作用下再次正向转动锁住第一锁紧块31，转向操作杆12由此被锁紧到车身11上从而保持展开状态，这样，使用者就可以站立到车身11上驾驶滑板车1了。
在本实施例中，两用锁紧件2设在转向操作杆12上，第一锁紧块31和第二锁紧块32设在车身11上。在其他实施例中，两用锁紧件2可以改为设在车身11上，而第一锁紧块31和第二锁紧块32则相应地改为设在转向操作杆12上。
如上所述仅为本发明创造的实施方式，不以此限定专利保护范围。本领域技术人员在本发明创造的基础上作出非实质性的变化或替换，仍落入专利保护范围。
