Description

Technical Field

[0001] This utility model relates to an obstacle avoidance structure and a personal transportation vehicle. Background Technology

[0002] To meet the needs of people of different heights, some mobility scooters for the elderly are equipped with seat lifting functions to facilitate users getting on and off the vehicle. To achieve the seat lifting function, a lifting device with a folding function is installed between the seat and the chassis of the mobility scooter. The lifting device generally includes a drive component and a folding lifting frame connected to the drive component. In actual use, we find that the rotating arm of the lifting frame may touch the frame of the mobility scooter, which will affect the lifting range and lifting effect of the lifting frame. Utility Model Content

[0003] The present invention aims to provide an obstacle avoidance structure and a personal transportation vehicle to solve the above-mentioned technical problems.

[0004] In view of this, the present invention provides an obstacle avoidance structure, comprising:

[0005] An obstacle avoidance structure includes an obstacle avoidance frame disposed on one side of a rotating arm, the obstacle avoidance frame having an obstacle avoidance opening corresponding to the rotating arm, the obstacle avoidance opening being adapted to provide the rotating arm with the obstacle avoidance space required for rotation.

[0006] Through the above technical solution, the rotating arm will rotate during the unfolding and retraction of the lifting device where the rotating arm is located. During the large-angle swing of the rotating arm, the end of the rotating arm can be guided into the avoidance opening on the avoidance frame. The avoidance space provided by the avoidance opening can further improve the rotational freedom of the rotating arm and avoid the rotating arm from colliding with other components.

[0007] Furthermore, the clearance frame is provided with a support surface corresponding to the rotating arm. The support surface is located on one side of the clearance opening, and the shape of the support surface is adapted to the shape of the side of the rotating arm near the clearance opening.

[0008] Through the above technical solution, when the end of the rotating arm is guided into the clearance opening during the large-angle swing of the rotating arm, the support surface located on one side of the clearance opening can support the side of the rotating arm. In the design, the shape of the support surface is adapted to the side shape of the rotating arm to ensure that the support surface can stably support the rotating arm. In the actual design, the smaller the angle between the support surface and the horizontal plane, the larger the angle that the rotating arm can rotate. The angle between the support surface and the horizontal plane can be determined according to the angle of the actual stroke key position of the rotating arm.

[0009] The supporting surface can be an arc-shaped surface or an inclined surface, and the supporting surface is preferably an inclined surface.

[0010] Furthermore, one side of the clearance opening has an opening, allowing the rotating arm to be guided through the opening into the clearance space provided by the clearance opening when it rotates.

[0011] With the above technical solution, the cross-section of the clearance opening can be "C" or "U". When the rotating arm swings to the end of its stroke, the clearance opening provides clearance space to accommodate the rotating arm. In this way, the swing stroke of the rotating arm is larger, and at the same time, it will not touch other parts during the large swing of the rotating arm.

[0012] Furthermore, the clearance is formed by two supporting parts and one fixing part. The fixing part is fixed to the chassis frame by fasteners. The supporting parts and the fixing part can be processed by integral molding.

[0013] Through the above technical solution, the obstacle avoidance frame can be fixed to the external chassis frame by the fasteners on the fixed part of the obstacle avoidance opening, ensuring the stability of the obstacle avoidance frame installation. Of course, the obstacle avoidance frame can also be fixed to the external frame by snap-fitting.

[0014] Furthermore, the surface of the fixing part is connected to the supporting surface.

[0015] Furthermore, there are multiple rotating arms, which are mainly used to improve the stability of the support during rotation.

[0016] Furthermore, the aperture width of the clearance is greater than the width of the area formed between the multiple rotating arms.

[0017] The purpose of this design is to ensure that multiple rotating arms can be smoothly guided into the clearance opening when they reach the end position of their stroke.

[0018] Furthermore, the rotating arm is one of the following: attitude adjustment arm, displacement compensation arm, and lifting arm.

[0019] Compared with the prior art, the beneficial technical effects of the present utility model are as follows: 1. The avoidance structure provided by this application can provide the avoidance space required for the rotation of the rotating arm, and the avoidance space provided by the avoidance opening can further improve the rotational freedom of the rotating arm and avoid the rotating arm from colliding with other components;

[0020] 2. The clearance frame provided in this application is provided with a support surface corresponding to the rotating arm. The support surface is located on one side of the clearance opening. When the end of the rotating arm is inserted into the clearance opening, the support surface located on one side of the clearance opening can support the side of the rotating arm. In the design, the shape of the support surface is adapted to the side shape of the rotating arm, which can ensure that the support surface can stably support the rotating arm.

[0021] Another technical solution adopted in this application is to provide a personal transportation vehicle, including the above-mentioned obstacle avoidance structure.

[0022] Through the above technical solution, the personal transportation vehicle provided in this application, due to the configuration of the above-mentioned avoidance structure, has the corresponding technical effect of the above-mentioned avoidance structure. Attached Figure Description

Detailed Implementation

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] This application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Example 1

[0032] Reference Figure 1 , Figure 2 An obstacle avoidance structure 100 includes an obstacle avoidance frame 11 disposed on one side of a rotating arm 10. The obstacle avoidance frame 11 is provided with an obstacle avoidance opening 12 corresponding to the rotating arm 10. The obstacle avoidance opening 12 is adapted to provide the rotating arm 10 with the obstacle avoidance space required for rotation.

[0033] During the unfolding and retraction of the lifting device, the rotating arm 10 will rotate. During the large-angle swing of the rotating arm 10, the end of the rotating arm 10 can be guided into the avoidance port 12 on the avoidance frame 11. The avoidance space provided by the avoidance port 12 can further improve the rotational freedom of the rotating arm 10 and prevent the rotating arm 10 from colliding with other components.

[0034] Reference Figure 3 The clearance frame 11 is provided with a support surface 13 corresponding to the rotating arm 10. The support surface 13 is located on one side of the clearance opening 12. The shape of the support surface 13 is adapted to the shape of the side 14 of the rotating arm 10 near the clearance opening 12. The support surface 13 can be an arc surface or an inclined surface, and the support surface 13 is preferably an inclined surface.

[0035] During the large-angle swing of the rotating arm 10, when the end of the rotating arm 10 enters the clearance opening 12, the support surface 13 located on one side of the clearance opening 12 can support the side 14 of the rotating arm 10. In the design, the shape of the support surface 13 is adapted to the shape of the side 14 of the rotating arm 10, which can ensure that the support surface 13 can stably support the rotating arm 10. In actual design, the smaller the angle of the support surface 13 relative to the horizontal plane, the larger the angle that the rotating arm 10 can rotate. The angle of the support surface 13 relative to the horizontal plane can be determined according to the angle of the actual stroke key position of the rotating arm 10.

[0036] Furthermore, one side of the clearance opening 12 has an opening, and when the rotating arm 10 rotates, it can be guided into the clearance space provided by the clearance opening 12 through the opening. The cross-section of the clearance opening 12 can be "C" shaped or "U" shaped. When the rotating arm 10 swings to the end position of its stroke, the clearance space provided by the clearance opening 12 can accommodate the rotating arm. In this way, the swing stroke of the rotating arm is larger, and at the same time, it will not touch other parts during the large swing of the rotating arm.

[0037] Furthermore, the clearance 12 is formed by two support parts 120 and one fixing part 121. The fixing part 121 is fixed to the chassis frame 15 by fasteners 122. The support parts 120 and the fixing part 121 can be processed by integral molding.

[0038] Through the above technical solution, the obstacle avoidance frame 11 can be fixed to the external chassis frame 15 by the fastener 122 on the fixing part 121 of the obstacle avoidance opening 12, so as to ensure the stability of the obstacle avoidance frame 11 installation. Of course, the obstacle avoidance frame 11 can also be fixedly installed on the external frame by snap-fitting. The fastener 122 can be a screw, threaded rod or other component.

[0039] Furthermore, the surface of the fixing part 121 is connected to the support surface 13, and the connection part can adopt a rounded transition to ensure the continuity of the connection between the surface of the fixing part 121 and the support surface 13.

[0040] Furthermore, there are multiple rotating arms 10, which are mainly used to improve the stability of the support during rotation. The diameter of the clearance opening 12 is greater than the width of the area formed between the multiple rotating arms 10. The purpose of this design is to ensure that the multiple rotating arms 10 can be smoothly guided into the clearance opening 12 when they rotate to the end position of their stroke.

[0041] Furthermore, the rotating arm 10 is one of the following: attitude adjustment arm, displacement compensation arm, and lifting arm.

[0042] The avoidance structure provided in this application can provide the avoidance space required for the rotation of the rotating arm 10. The avoidance space provided by the avoidance opening 12 can further improve the rotational freedom of the rotating arm 10 and prevent the rotating arm 10 from colliding with other components.

[0043] The clearance frame 11 provided in this application has a support surface corresponding to the rotating arm. The support surface is located on one side of the clearance opening. When the end of the rotating arm 10 is inserted into the clearance opening 12, the support surface 13 located on one side of the clearance opening 12 can support the side of the rotating arm 10. In the design, the shape of the support surface 13 is adapted to the shape of the side 14 of the rotating arm 10, which can ensure that the support surface 13 can stably support the rotating arm 10.

[0044] Example 2

[0045] Based on the same technical concept, this application provides a personal transportation vehicle 200. Please refer to [link / reference]. Figure 4 Similar to existing personal mobility vehicles, the personal mobility vehicle 200 of this embodiment includes a lifting structure 20, a seat 21, and wheels 22. At least one wheel 22 is equipped with an electric motor 23. The lifting structure 20 includes the rotating arm 10 of the above embodiment 1. In addition, the personal mobility vehicle 200 of this embodiment also includes the avoidance structure 100 of the above embodiment 1. After the avoidance structure 100 is installed on the personal mobility vehicle 200, it can provide the avoidance space required for the rotation of the rotating arm 10. The avoidance space can further improve the rotational freedom of the rotating arm 10 and prevent the rotating arm 10 from colliding with other components.
