Description

Technical Field

[0001] The utility model relates to the technical field of scooters, and particularly relates to an electric scooter with good safety performance. Background Art

[0002] The travel tools for disabled or elderly people with lower limb disabilities include scooters such as wheelchairs. Generally, the seats of scooters on the market are at a certain height from the ground, and the riders drive the scooters in a sitting position. With the development of scooter technology, riders can drive the scooter in a sitting position or a standing position. However, for the elderly, driving the scooter in a sitting position is safer.

[0003] For example, as shown in the Chinese utility model patent with the publication number CN 216861708 U, it discloses a new type of scooter, which includes a movable chassis, a seat and a connecting piece. One end of the connecting piece is connected to the movable chassis, and the other end of the connecting piece is connected to the seat. The connecting piece drives the seat to be in a low position or a high position on the movable chassis. There is an area on the movable chassis for the rider to place their legs forward. When the seat is in a low position above the movable chassis, the seat and the movable chassis provide a sitting-lying riding posture for the rider to directly drive the new type of scooter. In addition to retaining the traditional driving methods of sitting and / or standing of the scooter, the new type of scooter described in the utility model also adds a sitting-lying driving method, bringing a different sense of experience to the rider and being beneficial to expanding the diversity of product usage scenarios.

[0004] The existing scooters are as shown in the above structure, and they have the following technical problems, which directly affect the safety performance of the vehicle:

[0005] 1. As shown in the above patent, the existing scooters generally have a double-armrest structure, and a control handle is arranged on one of the armrests. There are the following technical problems: Since only the elbows or arms of the user contact the armrest when in use, on a flat road surface, this kind of armrest can meet the basic usage requirements such as supporting the arms. However, in scenarios such as uphill, downhill or bumpy roads, the support of the user's arms is significantly insufficient, and it is easy to have emotions such as tension and uneasiness, resulting in a greatly reduced sense of experience in use.

[0006] 2. In order to achieve battery life, many existing scooters are provided with a detachable battery structure. However, most of the wheelchair-type electric scooters on the market are as shown in the above patent, and the detachable battery is arranged between the seat base and the footrest. In this way, the bottom space of the scooter is occupied greatly, and the overall length of the vehicle is relatively large, resulting in that when driving into a narrow space such as an elevator, it can only go straight in and out. It is relatively smooth and convenient to enter the elevator, but when getting out of the elevator, it needs to be backed out, which is inconvenient to operate and prone to collisions.

[0007] 3. When the user steps on the pedals from the front of the vehicle to get on, the front end is heavy due to the front placement of the battery. In actual use, there is a high probability that the vehicle will tilt forward or become unstable when getting on the vehicle. Utility Model Content

[0063] As Figures 1 - 3 shown in the figure, the seat part 2 includes a seat main body 21 and a seat cushion 22 detachably installed on the seat main body 21. The seat main body 21 is detachably installed on the moving part 1, and the first armrest mechanism 41 and the second armrest mechanism 42 are respectively installed on both sides of the seat main body 21. Thus, the seat cushion 22 can be disassembled according to actual needs, such as cleaning, replacement, etc.

[0064] As Figure 5 shown in the figure, a guiding groove 121d and a connecting member 121e are provided on the rear wheel frame 121. An installation member (not shown in the figure, which can be a square socket pipe and can be locked with bolts) that cooperates with the connecting member 121e and a guiding post (not shown in the figure, which can be a square conduit) that is in limiting cooperation with the guiding groove 121d are provided at the bottom of the seat main body 21. Thus, the seat cushion 22 can be disassembled according to actual needs, such as cleaning, replacement, etc. The whole vehicle can also be disassembled. For example, the overall structure composed of the whole seat part 2, the armrest part 4, and the backrest 3 can be disassembled, which is convenient for loading into the trunk of a car.

[0065] It should be noted that a connecting block 23 is provided on the side of the seat main body 21. The first armrest body 411 and the second armrest body 421 are rotatably connected to the connecting block 23 through a rotating shaft 24. The first armrest body 411 and the second armrest body 421 are provided with limiting sliding grooves 410, and a limiting pin shaft 231 that is slidably matched with the limiting sliding grooves 410 is provided on the connecting block 23. The first armrest body 411 and the second armrest body 421 are basically the same in overall shape and are both in a C shape. The limiting sliding grooves 410 are provided at the bottom of the first armrest body 411 and the second armrest body 421 and are opened on the inner side wall. Thus, the rotation of the first armrest mechanism 41 and the second armrest mechanism 42 can be realized to meet various usage requirements, and the limiting of the first armrest body 411 or the second armrest body 421 is realized by the cooperation between the limiting sliding grooves 410 and the limiting pin shaft 231.

[0066] AsFigures 7 - 9 As shown, through the cooperation of the limit chute 410 and the limit pin shaft 231, the first armrest body 411 and the second armrest body 421 of this embodiment can at least have three usage states:

[0067] Specifically, taking the second armrest body 421 as an example: Assume that the straight line in the horizontal direction is L1, and the straight line where the upper end surface of the second armrest body 421 is located is L2, and the included angle between the two is A.

[0068] Then, preferably, in the normal usage state, the angle of A is 0 - 5°, as shown in Figure 3 and Figure 6 shown;

[0069] When the second armrest body 421 is flipped backward, the angle of A is preferably 75 - 95°, as shown in Figure 4 and Figure 7 shown; The beneficial effect of this is that it is convenient for users to get on and off the vehicle. When the user needs to get on and off the vehicle, the first armrest mechanism 41 or the second armrest mechanism 42 can be rotated and flipped backward, and the user can get on the vehicle from the side of the car, which is convenient and safe.

[0070] When the second armrest body 421 is pressed forward, the angle of A is preferably 15 - 18°. The beneficial effect of this is that when the user rides on this scooter for office work or dining, since the fixed armrest is generally higher than the tabletop, when moving forward directly, it will be blocked by the tabletop panel, resulting in too large a distance between the user and the tabletop, making it impossible to dine or work, etc. In order to adapt to these scenarios, the user can tilt the first armrest mechanism 41 and the second armrest mechanism 42 downward so that the front end of the armrest is lower than the tabletop panel, and easily enter the appropriate position to dine and work in the most comfortable state.

[0071] It should be noted that, in order to facilitate the switching of the above states, an adjustment handle 25 that is in limit cooperation with the rotating shaft 24 is further provided on the connection block 23. The adjustment handle 25 can be movably connected to the connection block 23 by means of hinge, and the bottom end can be in limit cooperation with the rotating shaft 24 by means of a dial. The rotating shaft 24 can be provided with a plurality of gear slots corresponding to the dial, and this structure can cooperate to achieve the positioning and locking effect.

[0072] As Figures 1 - 3 shown, the backrest 3 includes a backrest main body 31 and a backrest soft body 32 detachably mounted on the backrest main body 31. The backrest main body 31 and the seat main body 21 are rotatably connected by means of hinge. Thus, the backrest main body 31 can be folded relative to the seat main body 21, and the backrest soft body 32 is detachable to meet the usage requirements. The backrest soft body 32 or the seat soft body 22 can be detachably connected to the backrest main body 31 or the seat main body 21 by means of Velcro.

[0073] As Figures 1 - 4As shown in the figure, the anti-tilt scooter further includes an expansion part 6, which is detachably installed on the front wheel frame 111 and is located between the front wheel set 11 and the rear wheel set 12. Thus, the expansion part 6 can be a storage basket, the bottom of which can be detachably matched with the front wheel frame 111 in a card slot limiting manner, and the basket body can be limited by the front wheel frame 111 and the rear wheel frame 121. The expansion part 6 serves to store the items carried by the user, with strong practicability.

[0074] As Figure 5 shown in the figure, the rear wheel frame 121 is provided with a first limiting groove 121a for limiting and cooperating with the rechargeable battery 7, and an insertion interface 121b electrically connected to the single-chip microcomputer 51 is arranged in the first limiting groove 121a. A plug-in part matching with the insertion interface 121b is arranged on the rechargeable battery 7.

[0075] It should be noted that the rechargeable battery 7 is a lithium battery. A limiting protrusion 121c is arranged in the first limiting groove 121a, and a second limiting groove for limiting and cooperating with the limiting protrusion 121c is formed on the outer wall of the rechargeable battery 7. Thus, it is convenient to realize the detachable and limited installation of the rechargeable battery 7, with convenient use.

[0076] As Figures 1 - 6 shown in the figure, the moving part 1 of this embodiment further includes a rear shell 14, which is installed on the rear wheel frame 121 and can shield the driving motor 123 and the anti-tipping wheel set 13; the tail of the rear shell 14 is in an arc shape that converges inward. The front end of the rear shell 14 can be connected to the rear wheel frame 121 in a clamping manner, and the rear end can be fixedly connected to the rear wheel frame 121 through fasteners such as screws. The two anti-tipping wheels 131 are connected by a connecting shaft 132, and the connecting shaft 132 is rotatably sleeved on the rear wheel frame 121. The rear shell 14 is arranged at the rear of the vehicle. The rear shell 14 not only imitates the shape of the rear of a sports car, greatly improving the aesthetics of the scooter, making the scooter younger and suitable for more people, but also can realize a hidden design of the anti-tipping wheel set 13, avoiding the anti-tipping wheel set 13 from being exposed to the wind and sun, playing a certain protective role and extending the service life of the anti-tipping wheel set 13. The rear shell 14 of the present utility model combines aesthetics and practicability.

[0077] It should be noted that the parts not described otherwise can adopt the structures in the prior art. For example, the front wheel 112 can be a commercially available Mecanum wheel or an Omni wheel (universal tire) developed by Mazda Motor Corporation.

[0078] The present utility model provides an electric scooter with a brand-new structure. Compared with traditional electric scooters, its safety performance is mainly reflected in the following aspects:

[0079] 1. There is a fixed handle 44. When in use, the user can hold the fixed handle 44 at any time, which can greatly improve the safety performance and avoid nervousness, especially suitable for scenarios such as uphill, downhill or bumpy roads.

[0080] 2. The front wheel 112 is an omnidirectional wheel, which can not only smoothly achieve basic functions such as forward and backward movement, steering and in-situ rotation, but also has strong obstacle-crossing ability and good buffering ability, suitable for use on complex road conditions.

[0081] 3. There is an anti-tipping wheel set 13, which can effectively prevent the vehicle body from tilting backward or overturning.

[0082] 4. The rechargeable battery 7 is arranged on the rear wheel frame 121, which makes reasonable use of space and does not increase the space occupation of the whole vehicle. This enables the scooter of the present utility model to be designed shorter in the length direction. By controlling the rotation of the rear wheel 122 and cooperating with the omnidirectional front wheel 112, the in-situ rotation function of the whole vehicle can be realized. After testing, the rotation radius of this electric scooter can be in the range of 65 - 75 cm, that is, it can completely realize the in-situ turning function in narrow spaces such as elevators, facilitating entry and exit from elevators and better meeting the usage needs of the elderly, with good safety.

[0083] 5. The center of gravity of the whole vehicle is at the position of the seat part 2, with balanced force. The first armrest mechanism 41 and the second armrest mechanism 42 can rotate. The user can choose to get on the vehicle from the front or both sides of the seat part 2 according to needs, and each boarding method has high safety and there is no danger of the vehicle tilting forward or overturning due to boarding.

[0084] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
