Description

Technical Field

[0001] The present invention relates to the technical field of scooters, and in particular to a switchable electric scooter. Background Art

[0002] The frog scooter is also called the frog car. The frog scooter and the flat scooter are both very popular fitness and entertainment equipment in today's society. The frog scooter gets its name because the user looks like a frog swimming when riding. The frog scooter combines the principles of mechanics and ergonomics, and uses the outward and inward thrust of the legs to generate thrust, which can naturally exercise the sartorius muscle that is rarely active in normal times.

[0003] Chinese patent publication number CN105711705B discloses an electric frog-style scooter, which includes a front curved pipe and a skateboard hinged on both sides of the front curved pipe. A universal wheel is hinged at the rear of the skateboard. The front curved pipe is connected to a front fork, and the front fork is connected to a front wheel. The front wheel is driven forward by an electric motor, and can be moved forward without pedaling, enriching the function of the frog-style scooter.

[0004] In addition, the front wheel of the flat-type electric scooter is also driven by an electric motor. The principle is the same as that of the electric frog scooter. It has the dual functions of single-leg pedaling of a human-powered scooter and electric drive.

[0005] But in reality, the movement principles of frog scooters and flat scooters are different. There is no scooter that can combine the triple functions of flat scooters, frog scooters and electric scooters at the same time, so there is room for improvement. Summary of the Invention

[0006] The present invention addresses the shortcoming of existing scooters that there is insufficient space for modifying their functions, and provides an electric scooter that can switch between three functions: a frog scooter, a flat scooter, and an electric scooter.

[0007] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0008] A switchable electric scooter comprises a handlebar, a front wheel arranged at the bottom of the handlebar, and a driving mechanism for driving the front wheel to rotate. A mounting seat is convexly provided at the lower side of the handlebar, two clamping plates are pivotally connected to the mounting seat on both sides, and a double-tread plate is formed when the clamping plates are closed. A universal rear wheel is rotatably provided at one end of the clamping plate away from the mounting seat, and the universal rear wheel comprises a wheel seat rotatably provided below the clamping plate and a wheel rotatably provided on the wheel seat. A linkage locking mechanism is provided between the clamping plate and the mounting seat, and the linkage locking mechanism comprises a first locking member connected to the mounting seat, a first locking member connected to the mounting seat, and a second locking member connected to the mounting seat. When the first locking member is inserted into the tensioning plate, the second locking member is automatically extended, and the second locking member is automatically retracted when the first locking member is disengaged from the tensioning plate. A limiting groove is provided at the upper end of the wheel seat. When the universal rear wheel and the front wheel are in the same direction of rotation, the second locking member is extended and inserted into the limiting groove to limit the horizontal rotation of the wheel seat.

[0009] By adopting the above scheme, the scooter can be driven forward through the driving mechanism without manpower, and the opening and closing plates are arranged to be foldable into a double-stepping flat plate style. Combined with the linkage locking mechanism, the front and rear positions of the first locking member can be adjusted by simple operation of the operating component. As the first locking member moves forward or backward, the opening and closing plates can be quickly switched between the openable and closed states, and when the opening and closing plates are opened, the universal rear wheel is kept in a horizontal rotation state; when the opening and closing plates are closed, the universal wheel and the front wheel are kept in a synchronous rotation state. The above structure can quickly switch between the three modes of electric scooter, frog scooter and flat scooter.

[0010] Preferably, the second locking member includes a accommodating groove arranged in the opening and closing plate, a lifting block vertically lifted in the accommodating groove, and at least one locking block protruding from the lower end of the lifting block and extending out of the lower end of the opening and closing plate. A first elastic member is provided at the bottom of the accommodating groove and the lower end of the lifting block, with both ends abutting against the two.

[0011] By adopting the above scheme, when the locking block rises, it can be disengaged from the limiting groove, and the universal rear wheel is in a horizontally rotating state. In conjunction with the opening and closing of the opening and closing plate, the scooter is switched to the state of a frog scooter, and the first elastic member drives the locking member to be in an ascending state under normal circumstances; when the locking block descends, it can be plugged into the limiting groove, and the universal rear wheel cannot rotate horizontally, but can only rotate synchronously with the front wheel. Combined with the first locking member, the scooter is driven to switch to the state of a flat scooter.

[0012] Preferably, the first locking member includes a mounting rod protruding from below the tensioning plate at the end of the mounting seat away from the handlebar rod and extending to the end of the tensioning plate away from the mounting seat, a matching block protruding vertically at the end of the mounting rod away from the mounting seat, and a movable locking block that can be moved closer to or away from the tensioning plate and is provided at the end of the matching block away from the tensioning plate, and a limiting lock groove is recessed at the end of the tensioning plate away from the mounting seat in a cross shape with the accommodating groove.

[0013] Using the above scheme, the mounting rod is used to support the mating block, and the movable locking block cooperates with the mating block to realize the forward or backward movement of the movable locking block. The limiting lock groove and the accommodating groove are in a cross-intersection state. When the movable locking block is simultaneously plugged into and matched with the two limiting lock grooves, the opening of the tensioning plate can be limited.

[0014] Preferably, the linkage component includes a linkage block movably arranged in the limit lock groove, a second elastic member arranged at the bottom of the limit lock groove to drive the linkage block to be in an extended state, a matching inclined surface is provided at the upper end of the locking block, and a pressing inclined surface that cooperates with the matching inclined surface is provided at the end of the linkage block close to the second elastic member.

[0015] By adopting the above scheme, the setting of the linkage block can shorten the telescopic stroke of the movable locking block, thereby reducing the setting volume of the movable locking block. At the same time, when the movable locking block disengages from the limit lock groove, the linkage block can block the limit lock groove, thereby preventing dirt from entering the accommodating groove and the limit lock groove. The pressing inclined surface and the mating inclined surface cooperate with each other, and as the linkage block contracts, the lifting block can be driven down; as the linkage block extends, the lifting block automatically rises under the action of the first elastic member.

[0016] Preferably, when the second elastic member is in a normal state, the end of the linkage block away from the second elastic member is flush with the opening of the limiting lock slot.

[0017] With the above solution, the linkage block completely blocks the limit lock slot under normal conditions, significantly improving the dust prevention effect.

[0018] Preferably, the operating component includes a screw fixed at the end of the mating block away from the mounting seat, a groove recessed at the end of the movable locking block close to the mating block, and a through hole provided at the bottom of the groove for the screw to pass through, and a threaded knob is provided on the screw for pressing the movable locking block toward the limiting lock groove.

[0019] By adopting the above scheme, the movable locking block moves forward or backward by rotating the threaded knob in or out. When the movable locking block moves forward, it can be inserted into the limit lock groove; when the movable locking block loses the pressing effect of the threaded knob, the movable locking block automatically moves backward under the resetting effect of the linkage block.

[0020] Preferably, one end of the movable locking block close to the limiting lock slot is provided with an introduction slope for facilitating introduction into the limiting lock slot.

[0021] By adopting the above solution, the setting of the guide slope can accelerate the insertion of the movable lock block into the limit lock groove, thereby playing a guiding role.

[0022] Preferably, a slot communicating with the accommodating groove is provided on one side opposite to the opening and closing plate, and an elastic plug for closing the slot is provided on the slot.

[0023] With the above solution, the slot is provided to enable installation of the second locking member, and the elastic plug is used to close the slot.

[0024] Preferably, the upper ends of the opening and closing plates are evenly distributed with anti-slip convex strips.

[0025] With the above solution, the provision of the anti-skid ridges can increase the friction with the sole of the foot, thus preventing slipping when stepping on it.

[0026] Preferably, the driving mechanism is a motor, the motor shaft is electrically connected to the front wheel, and a control button for starting and closing the motor is provided at the upper end of the handlebar.

[0027] By adopting the above solution, the motor is used to drive the front wheel to rotate, so that the scooter can slide automatically without external force.

[0028] The present invention has significant technical effects due to the adoption of the above technical solutions:

[0029] 1. The driving mechanism allows the scooter to be driven forward without human effort. The opening and closing plates are arranged to be foldable into a double-pedal flat plate. Combined with a linkage locking mechanism, the front and rear positions of the first locking member can be adjusted by simple operation of the operating component. As the first locking member moves forward or backward, the opening and closing plates can be quickly switched between an openable or closed state. When the opening and closing plates are opened, the universal rear wheel is kept in a horizontal rotation state. When the opening and closing plates are closed, the universal wheel and the front wheel are kept in a synchronous rotation state. The above structure can quickly switch between three modes: electric scooter, frog scooter and flat scooter.

[0030] 2. The linkage locking mechanism also includes a linkage component. The setting of the linkage block can shorten the telescopic stroke of the movable lock block, thereby reducing the setting volume of the movable lock block. At the same time, when the movable lock block disengages from the limit lock groove, the linkage block can block the limit lock groove, thereby preventing dirt from entering the accommodating groove and the limit lock groove. The pressing inclined surface of the linkage block cooperates with the matching inclined surface of the second locking piece. As the linkage block contracts, the second locking piece can be driven to descend; as the linkage block extends, the second locking piece automatically rises under the action of the first elastic piece.
