Description

An electric scooter

Technical field

The present invention relates to the field of electric scooters, and in particular to an electric scooter.

Background technique

Electric scooters are a new type of personal travel tool. They use electric energy as a driving force and can quickly and conveniently travel short distances in the city. For scooters currently on the market, users often need to store items while traveling. At present, The electric scooter does not have a matching shelf box and cannot conveniently carry shopping bags, backpacks or other items.

Due to the limited space of existing electric scooters, when a shelf box is installed on an electric scooter, how to ensure the compatibility of the shelf box and the seat in the limited space without affecting the user experience is a technical problem that needs to be solved. At the same time, the current electric scooters are mainly used for riding on flat roads. When riding on rugged and uneven roads, the whole vehicle will experience large bumps, poor riding comfort, and even rollover, and the driver and passengers will be unable to control the entire vehicle. .

The shock absorption method used in existing electric scooters is that each wheel is provided with a shock absorber rod, and both ends of the shock absorber rod are connected to the frame through rigid connectors. One end of the shock rod is connected to the axle and the other end is connected to a fixed point on the frame.

The shock absorber rod is rigidly connected to the frame to provide vertical support and reduce the impact of road vibration and impact on the scooter.

The disadvantage of the above method is that the shock absorber may not be able to effectively absorb lateral impacts and vibrations, and the scooter will roll when turning or walking on uneven roads.

When the scooter turns or tilts, the center of gravity above the body shifts, forming a centrifugal moment. This centrifugal moment pushes the body outboard, and rigidly connected shock absorber rods do not provide enough elasticity to absorb or cushion this moment. causing the scooter to roll over.

When driving on uneven roads, the vibrations and bumps encountered by the wheels are transmitted to the body of the scooter. The car body will be impacted and shake left and right, increasing the risk of rollover.

The working process of the present invention is as follows:

When it is necessary to sit, the seat mechanism 4 changes from the folded state to the upright state, and the support member 33 drives the notch 49 to snap into the limiting tube under the action of the elastic torsion member. The locking head 38 is snapped into the upright locking groove 43 .

When it is necessary to stand, when the seat mechanism 4 changes from the upright state to the folded state, the locking portion exits the upright locking groove 43 . The support member 33 rotates toward the shelf 2. When the seat mechanism 4 is folded in place, the locking portion is locked into the folding locking groove 44.

Specifically, when the driver sits on the seat cushion, the line of action of the person's gravity is in front of the bearing member 27, and gravity causes the notch 49 of the support member 33 to always engage with the limiting tube. When the vehicle is driving, Occasionally, the person's center of gravity passes behind the bearing member 27. Since the locking head 38 is stuck in the upright locking groove 43, the support member 33 cannot rotate counterclockwise, so the seat cushion will not fall backward.

When the handle 41 is lifted upward, the handle 41 rotates around the second hinge pin 46, and the handle 41 drives the sliding plate 36 to move along the linear direction of the first guide pin 47 and the second guide pin 48 through the connecting rod 29. At this time The locking head 38 withdraws from the upright locking groove 43 .

At this time, the support member 33 can rotate counterclockwise, that is, the seat can tilt backward. When the guide portion contacts the guide seat 30, the support member 33 continues to rotate counterclockwise, and the seat cushion 31 rotates clockwise around the first hinge pin 45 until The seat cushion 31 rotates to a horizontal position, and under the elastic force of the tension spring 39, the locking head 38 is snapped into the folding locking groove 44, so that the seat cushion 31 is completely hidden inside the shelf 2.

On the contrary, when the seat is in the folded state, when the handle 41 is pulled and the support member 33 is rotated counterclockwise, the seat can be returned to the upright state.

When the rider stands or sits on the skateboard and the human body tilts to the left/right, the frame 1 is driven to tilt left/right synchronously. The left end of the connecting sleeve 52 is low/high and the right end is high/low. The connecting sleeve 52 torsionally stores energy. Colloid 51, the elastic energy storage colloid 51 undergoes torsional deformation. During this process, the elastic energy storage colloid 51 will absorb part of the torsional energy, convert it into elastic potential energy, and store this part of the energy in the elastic energy storage colloid 51.

The elastic energy storage colloid 51 absorbs and attenuates torsional energy through internal friction and loss damping. When the torsional force ends, the elastic energy storage colloid 51 releases the stored elastic energy, converts the torsional energy into heat energy and provides reverse restoring force.

The front shock absorber 6 and the rear shock absorber 7 are arranged centrally. The two ends of the front shock absorber 6 are connected to the front swing frame 9 and the vehicle frame 1 through joint bearings 12 respectively. The two ends of the rear shock absorber 7 are respectively connected to the front swing frame 9 and the vehicle frame 1 through joint bearings 12. The bearing 12 is connected to the rear swing frame 10 and the frame 1. The front shock absorber 6, the rear shock absorber 7, and the elastic shock absorber 8 can allow the body to produce corresponding roll within a certain angle range, and when it reaches its limit Provides resilience.

The elastic shock absorbing device 8 plays a role in isolating the four tires from the skateboard. The circumferential tooth surfaces of the four tires are always in contact with the road surface. The elastic shock absorbing device 8 realizes shock absorption and torsional separation. Due to the elastic energy storage colloid 51, the torque is To store and release energy, the elastic energy storage colloid 51 isolates torsion and vibration inside the elastic energy storage colloid 51 at the front and rear ends of the frame 1, thereby reducing the vibration and torsion transmitted to the rear swing frame assembly and the front swing frame assembly. The elastic energy storage colloid 51 plays the role of shock absorption and energy absorption during torsion.

Elastic deformation can occur when subjected to torsional or rotational loading. The elastic properties of the elastic shock absorbing device 8 allow it to deform when subjected to external force, and to return to its original shape after the external force is removed.
