An electric scooter

Abstract

An electric scooter includes a frame, a seat mechanism, and a rack. The rack is fixedly connected to the frame, and the seat mechanism is folded and connected to the frame. When the seat mechanism is folded, it is folded into the rack. Integrating the rack and seat onto the frame allows the seat to be folded and hidden inside the rack when the rider is standing, minimizing the space occupied by the seat mechanism. Simultaneously, an elastic shock-absorbing device absorbs and attenuates torsional energy, reducing the transmission of torsional force and isolating torsional vibrations.

Description

Technical Field

[0001] This invention relates to the field of electric scooters, and more specifically to an electric scooter. Background Technology

[0002] Electric scooters are a new type of personal transportation tool that uses electricity as a power source. They can be used for quick and convenient short-distance travel in the city. Currently, electric scooters on the market often have the need to store items while traveling, but they do not have matching racks or boxes, making it inconvenient to carry shopping bags, backpacks, or other items.

[0003] Due to the limited space available on existing electric scooters, a key technical challenge is ensuring compatibility between the rack and seat within this limited space, without compromising the user experience. Furthermore, current electric scooters are primarily designed for riding on flat surfaces. Riding on uneven or bumpy roads results in significant wobbling, poor riding comfort, and even tipping over, making it difficult for the rider to control the scooter.

[0004] The current shock absorption method used in electric scooters is that each wheel is equipped with a shock absorber, and both ends of the shock absorber are connected to the frame via rigid connectors. One end of the shock absorber is connected to the axle, and the other end is connected to a fixed point on the frame.

[0005] The shock absorber is rigidly connected to the frame, providing vertical support and reducing the impact of road vibrations and shocks on the scooter.

[0006] However, the drawback of the above method is that the shock absorber may not be able to effectively absorb lateral impacts and vibrations, and the scooter will tilt when turning or riding on uneven roads.

[0007] When a scooter turns or tilts, the center of gravity shifts above the scooter, creating a centrifugal moment. This moment pushes the scooter outwards, and the rigidly connected shock absorbers cannot provide enough elasticity to absorb or cushion this moment, causing the scooter to tip over.

[0008] When riding on uneven surfaces, the vibrations and bumps encountered by the wheels are transmitted to the scooter. The scooter will be impacted, wobbling from side to side, increasing the risk of tipping over. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention proposes an electric scooter, the specific technical solution of which is as follows:

[0022] The shelf, the load-bearing member, and the limiting member are connected to the connector;

[0023] The seating mechanism is hinged to the support member and folds into the shelf around the support member;

[0024] The seat mechanism includes a seat cushion assembly, a support component, and a locking assembly;

[0025] The lower end of the support is hinged to the carrier, and the seat cushion assembly is mounted on top of the support;

[0026] An elastic torsion member is provided between the support member and the load-bearing member. The fixed end of the elastic torsion member is connected to the load-bearing member, and the torsional end of the elastic torsion member is connected to the support member.

[0028] The locking assembly is located inside the support member. The locking assembly has a sliding locking part. The bearing member is provided with an upright locking groove / protrusion and a folding locking groove / protrusion that cooperate with the locking part.

[0029] When the seat mechanism is in the upright position, the elastic torque member drives the support member to cooperate with the limiting member, and the locking part cooperates with the upright locking groove / protrusion to keep the seat mechanism in the upright position.

[0030] When the seat mechanism is in the folded state, the locking part cooperates with the folding locking groove / protrusion to keep the seat mechanism in the folded state.

[0031] Furthermore: the front shock absorber, the elastic damping device at the front end of the frame, the elastic damping device at the rear end of the frame, and the rear shock absorber are arranged centrally along the length of the frame.

[0032] Furthermore: the elastic damping device includes an energy storage shell, an elastic energy storage colloid, and a connecting sleeve;

[0033] The energy storage shell is fixedly connected to the bottom front end of the vehicle frame, and the elastic energy storage gel has a through hole in the middle, which is consistent with the width direction of the vehicle frame;

[0034] The connecting sleeve is inserted into the through hole, and its two ends extend out of the through hole at equal distances.

[0035] Furthermore: the connecting sleeve is provided with a plurality of reinforcing ribs along the circumferential direction, and each reinforcing rib is undulating along the axial direction of the connecting sleeve; a slot adapted to the structure of the reinforcing rib is provided in the through hole, and the slot and the reinforcing rib are engaged by a concave-convex fit.

[0036] Furthermore, the frame is connected to a column, which has a folding structure.

[0044] The beneficial effects of this invention are as follows:

[0045] This invention integrates a shelf and seat onto a vehicle frame. When the driver is standing, the seat can be folded and hidden inside the shelf, minimizing the seat's footprint and ensuring uninterrupted operation. Even when the seat is flat on the guide seat, the shelf can still hold personal items. The shelf maintains its cargo-carrying function regardless of whether the seat is upright or folded. When the driver or passenger stands on the frame and leans left or right, the frame tilts synchronously, lowering / raising the left end and raising / lowering the right end of the connecting sleeve. This causes the connecting sleeve to twist the elastic energy-storing colloid, resulting in torsional deformation. During this process, the elastic energy-storing colloid absorbs some torsional energy and converts it into elastic potential energy, storing this energy within the colloid. By incorporating an elastic damping device to absorb and attenuate torsional energy, the transmission of torsional force is reduced, and torsional vibrations are isolated.

[0065] like Figures 1 to 15 As shown:

[0066] An electric scooter includes a frame 1, a seat mechanism 4, a connector 26, a rack 2, a column 3, and a shock absorption system.

[0067] The frame 1 has an approximate boat-shaped structure. The shelf 2 is fixedly connected to the frame 1, the seat mechanism 4 is folded and connected to the frame 1, and the lower end of the upright 3 is rotatably connected to the front end of the frame 1. Two handles are located on both sides of the upper end of the upright 3, and the handles are used to rotate the upright 3 left and right. The upright 3 drives the wheels to turn through the steering mechanism 5. The upright 3 has a foldable structure. When folded, the seat mechanism 4 folds into the shelf 2, and the upper section of the upright 3 folds laterally, achieving the minimum height of the entire vehicle for easy storage.

[0068] The frame 1 is connected to a shock absorption system, which includes a front shock absorber 6, a rear shock absorber 7, an elastic damping device 8, a front swing arm assembly, and a rear swing arm assembly.

[0076] The elastic damping device 8 includes an energy storage housing 50, an elastic energy storage gel 51, and a connecting sleeve 52. The energy storage housing 50 is fixedly connected to the bottom of the front end of the frame 1 by bolts. The elastic energy storage gel 51 is made of EPDM rubber. A through hole 55 is provided in the middle of the elastic energy storage gel 51. The through hole 55 is consistent with the width direction of the frame 1.

[0077] The connecting sleeve 52 is inserted into the through hole 55, and both ends of the connecting sleeve 52 extend out of the through hole 55 at equal distances.

[0078] The connecting sleeve 52 is provided with multiple reinforcing ribs 53 along the circumferential direction, and each reinforcing rib 53 is undulating along the axial direction of the connecting sleeve 52. A groove 54 adapted to the structure of the reinforcing rib 53 is provided in the through hole 55. The groove 54 and the reinforcing rib 53 are matched with each other to prevent the connecting sleeve 52 from sliding out of the through hole 55 under force.

[0079] The front swing arm 9 includes a front transverse shaft 15 and two front swing arms 16, which form a V-shaped bracket. The front transverse shaft 15 is connected between the two front swing arms 16, and the V-shaped bracket allows for a more even distribution of load. The rear swing arm 10 has the same structure as the front swing arm 9, which makes the entire frame 1 have a uniform load.

[0080] The inner end of the front swing arm 16 is hinged to the connecting end of the corresponding connecting sleeve 52, and the outer end of the front swing arm 16 is provided with a support assembly, on which the wheel hub assembly 11 is mounted. A steering mechanism 5 is provided on the front swing arm assembly, which drives the front wheels to steer.

[0081] The support assembly includes a rotating device and a base 19. The rotating device includes a support sleeve 17 and a rotating shaft 18. The rotating shaft 18 passes through the support sleeve 17 and rotates relative to the support sleeve 17.

[0082] A first lower support seat is provided on the front transverse axle 15, and a first upper support seat is provided at the bottom front end of the frame 1. The lower end of the front shock absorber 6 is fixedly connected to the outer ring of the spherical bearing, and the inner ring of the spherical bearing is fitted on the support pin of the first lower support seat. The upper end of the front shock absorber 6 is fixedly connected to the outer ring of the spherical bearing, and the inner ring of the spherical bearing is fitted on the support pin of the first upper support seat.

[0083] The steering mechanism 5 includes a first swing arm 22, a second swing arm 23, a push-pull rod 24, and a pull rod 25. The support sleeve 17 is fixedly connected to the outer end of the front swing arm 16 by welding / bolt. The inner ends of the first swing arm 22 and the second swing arm 23 are respectively fixedly connected to the rotating shaft 18 on one of the front swing arms 16.

[0084] Pulling rod 25 drives the first swing arm 22 to rotate. The outer end of the first swing arm 22 is hinged to the first end of the push-pull rod 24, and the second end of the push-pull rod 24 is hinged to the outer end of the second swing arm 23.

[0085] The shelf 2, the load-bearing component 27, and the limiting component 28 are fixedly connected to the connector 26, which is connected to the frame 1. In this embodiment, the shelf 2, the load-bearing component 27, the limiting component 28, and the connector 26 form the shelf 2 assembly, which is detachably connected to the frame 1. Alternatively, the connector 26 can be part of the frame 1, and the shelf 2, the load-bearing component 27, and the limiting component 28 can be directly connected to the frame 1.

[0086] The support member 27 is located between the shelf 2 and the limiting member 28. The seat mechanism 4 is hinged to the support member 27. The seat mechanism 4 can be folded into the shelf 2 by rotating about the support member 27 toward the shelf 2. The limiting member 28 restricts the seat mechanism 4 from the corner away from the shelf 2 and provides force support for the seat mechanism 4.

[0087] The seat mechanism 4 includes a seat cushion assembly, a support member 33, and a locking assembly.

[0088] The support member 33 is a strip-shaped plate structure. A locking part is provided at the lower part of the support member 33, and a locking groove 54 / locking platform is provided on the limiting member 28 to cooperate with the locking part.

[0089] Specifically, the engaging part is a notch 49, and the limiting member 28 is a limiting tube, with the arc surface of the limiting tube and the notch 49 having a concave-convex fit.

[0090] The lower end of the support member 33 is hinged to the bearing member 27. An elastic torsion member is provided between the support member 33 and the bearing member 27. The elastic torsion member is a second torsion spring 35. The fixed end of the elastic torsion member is connected to the bearing member 27, and the torsion end of the elastic torsion member is connected to the support member 33.

[0091] The seat cushion assembly is installed on the top of the support member 33, and the locking assembly is located inside the support member 33. The locking assembly has a sliding locking part, and the support member 27 is provided with an upright locking groove 43 / protrusion and a folding locking groove 44 / protrusion that are in concave-convex cooperation with the locking part.

[0092] When the seat mechanism 4 is in the upright position, the elastic torque member drives the support member 33 to cooperate with the limiting member 28, and the locking part cooperates with the upright locking groove 43 / protrusion, so that the seat mechanism 4 remains in the upright position;

[0093] When the seat mechanism 4 is in the folded state, the locking part cooperates with the folding locking groove 44 / protrusion to keep the seat mechanism 4 in the folded state.

[0094] One specific implementation of the locking mechanism:

[0095] The locking mechanism includes a sliding plate 36, a locking head 38, a tension spring 39, a hanging lug 40, and a handle 41. The locking head 38 is the locking part of the locking mechanism. The sliding plate 36 has a guide groove 37 along its length. The support member 33 has a first guide pin 47 and a second guide pin 48 along its length. The first guide pin 47 and the second guide pin 48 extend into the corresponding guide groove 37. The sliding plate 36 slides up and down along the support member 33.

[0096] The sliding plate 36 is provided with a hanging ear 40, and a tension spring 39 is connected between the hanging ear 40 and the support member 33. When the seat mechanism 4 is in the upright state / folded state, the tension spring 39 pulls the sliding plate 36, causing the locking head 38 to engage with the upright locking groove 43 / folded locking groove 44.

[0097] A handle 41 is hinged to the upper end of the support member 33. The handle 41 is foldable and is hinged to the support member 33 via a second hinge pin 46. The middle part of the handle 41 is hinged to the first end of the connecting rod 29, and the second end of the connecting rod 29 is hinged to the sliding plate 36. A baffle 42 is provided on the support member 33, and a slot is provided on the baffle 42. The handle 41 extends out of the slot. The handle 41 can only swing around the first hinge pin 45 within the slot.

[0098] The seat cushion assembly includes a seat cushion 31 and a guide portion, which is a guide slider 32. The seat cushion 31 is hinged to the upper end of the support member 33 via a first hinge pin 45. A first torsion spring 34 is provided between the seat cushion 31 and the support member 33. The fixed end of the first torsion spring 34 is connected to the support member 33, and the rotating end of the first torsion spring 34 is connected to the seat cushion 31. After the seat cushion 31 opens relative to the support member 33, the first torsion spring 34 causes the seat cushion 31 to automatically return to the horizontal position.

[0099] A guide seat 30 is provided inside the shelf 2. The support member 33 rotates around the load-bearing member 27 into the shelf 2. After the guide part contacts the guide seat 30, the seat opens relative to the support member 33. The guide part slides out from the head to the tail along the guide seat 30, and the seat cushion 31 is placed flat on the guide seat 30. The locking part is engaged in the folding locking groove 44, and the entire seat mechanism 4 is hidden inside the shelf 2. A protruding arc-shaped structure is provided between the upright locking groove 43 and the folding locking groove 44. The locking part slides into the upright locking groove 43 or the folding locking groove 44 along the arc-shaped structure.

[0100] The working process of this invention is as follows:

[0101] When sitting is required, the seat mechanism 4 changes from a folded state to an upright state. Under the action of the elastic torque member, the support member 33 drives the notch 49 to engage with the limiting tube. The locking head 38 engages with the upright locking groove 43.

[0102] When standing is required, the seat mechanism 4 changes from an upright state to a folded state, and the locking part disengages from the upright locking groove 43. The support member 33 rotates toward the shelf 2, and when the seat mechanism 4 is folded into place, the locking part engages with the folding locking groove 44.

[0103] Specifically, when the driver sits on the seat, the line of action of the person's weight is in front of the support member 27. The weight causes the notch 49 of the support member 33 to always engage with the limiting tube. When the vehicle is in motion, the person's center of gravity occasionally crosses the rear of the support member 27. Since the locking head 38 is locked in the upright locking groove 43, the support member 33 cannot rotate counterclockwise, so the seat will not tilt backward.

[0104] When the handle 41 is lifted upward, the handle 41 rotates around the second hinge pin 46. The handle 41 drives the sliding plate 36 to move along the straight line of the first guide pin 47 and the second guide pin 48 through the connecting rod 29. At this time, the locking head 38 retracts from the vertical locking groove 43.

[0105] At this time, the support member 33 can rotate counterclockwise, that is, the seat can tilt backward. When the guide part contacts the guide seat 30, the support member 33 continues to rotate counterclockwise, while the seat cushion 31 rotates clockwise around the first hinge pin 45 until the seat cushion 31 rotates to the horizontal. Under the elastic force of the tension spring 39, the locking head 38 is engaged in the folding locking groove 44, so that the seat cushion 31 is completely hidden inside the shelf 2.

[0106] Conversely, when the seat is folded, pulling the handle 41 and rotating the support 33 counterclockwise will restore the seat to an upright position.

[0107] When the rider stands or sits on the skateboard, the body tilts to the left or right, causing the frame 1 to tilt to the left or right in sync. The left end of the connecting sleeve 52 is lower / higher, and the right end is higher / lower. The connecting sleeve 52 twists the elastic energy storage colloid 51, causing the elastic energy storage colloid 51 to undergo torsional deformation. During this process, the elastic energy storage colloid 51 absorbs a portion of the torsional energy and converts it into elastic potential energy, storing this energy in the elastic energy storage colloid 51.

[0108] 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, converting the torsional energy into heat energy and providing a reverse restoring force.

[0109] The front shock absorber 6 and the rear shock absorber 7 are both centrally arranged. The two ends of the front shock absorber 6 are connected to the front swing frame 9 and the frame 1 respectively through spherical bearings. The two ends of the rear shock absorber 7 are connected to the rear swing frame 10 and the frame 1 respectively through spherical bearings. The front shock absorber 6, the rear shock absorber 7, and the elastic damping device 8 can allow the vehicle body to produce corresponding body roll within a certain angle range and provide restoring force when it reaches its limit.

[0110] The elastic damping device 8 isolates the four tires from the skid plate, ensuring that the circumferential tooth surfaces of the four tires remain in contact with the road surface. This elastic damping device 8 achieves shock absorption and torsional separation. Due to the storage and release of torque energy by the elastic energy storage gel 51, the elastic energy storage gel 51 isolates torsion and vibration within the elastic energy storage gel 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 gel 51 plays a role in shock absorption and energy absorption during torsion.

[0111] Elastic deformation can occur when subjected to torsional force or rotational loading. The elastic properties of the elastic damping device 8 allow it to deform when subjected to external force and return to its original shape after the external force is removed.

[0112] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
