[0049] In the related art, the wiring harness of a foldable mobility scooter is prone to becoming tangled when the scooter is unfolded or folded.

[0050] To address the above technical issues, the present invention provides a mobility scooter whose chassis includes a first chassis frame and a second chassis frame that are slidably connected. The first chassis frame can slide relative to the second chassis frame. When the mobility scooter needs to be stored, the first chassis frame slides relative to the second chassis frame for storage; when the mobility scooter needs to be unfolded, the first chassis frame slides relative to the second chassis frame for unfolding.

[0051] The chassis provided in the embodiment of the present application is configured as a retractable chassis, which can be unfolded and folded, so the folded mobility scooter occupies little space and is easy to carry.

[0052] The chassis provided in the embodiment of the present application also includes a wire harness storage mechanism, which can uniformly and regularly store the wire harnesses set on the chassis to avoid confusion and tangling of the wire harnesses.

[0053] The wiring harness storage mechanism of the embodiment of the present application includes a wiring harness and a wiring harness box. The wiring harness is arranged in the wiring harness box. During the expansion and storage of the chassis, the wiring harness box can constrain the movement trajectory of the wiring harness, avoid the wiring harness from being tangled and tangled, and ensure the normal use of the mobility scooter; it can also avoid damage to the wiring harness and protect the life of the wiring harness.

[0054] At the same time, the wiring harness is neatly and uniformly stored to improve the aesthetics of the vehicle.

[0055] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0056] To facilitate the description of the embodiments of the present application, the coordinate system in the accompanying drawings is explained, wherein the X-axis direction represents the first horizontal direction, which can be the front and rear directions of the mobility scooter, and this direction is consistent with the forward and backward directions of the mobility scooter; the Y-axis direction represents the second horizontal direction, which can be the left and right directions of the mobility scooter; the Z-axis direction represents the vertical direction, which can be the height direction of the mobility scooter.

[0057] like Figure 1 As shown, the mobility scooter 100 provided in the embodiment of the present application includes a chassis 10, a traveling mechanism 50, a steering mechanism 40 and a connecting rod folding mechanism 30, wherein the chassis 10 is configured as a load-bearing unit of the entire mobility scooter 100, and the traveling mechanism 50, the steering mechanism 40 and the connecting rod folding mechanism 30 are respectively arranged on the chassis 10.

[0058] The chassis 10 includes a first chassis frame 11 and a second chassis frame 12 , the first chassis frame 11 and the second chassis frame 12 are slidably connected, and the first chassis frame 11 can slide relative to the second chassis frame 12 , and the two at least partially overlap along the first horizontal direction.

[0059] When the link folding mechanism 30 is actuated, the entire mobility scooter 100 can be folded or unfolded. The link folding mechanism 30 is linked to the chassis 10. When the link folding mechanism 30 is folded, the chassis 10 is retracted, and when the link folding mechanism 30 is unfolded, the chassis 10 is unfolded.

[0060] The traveling mechanism 50 includes traveling wheels and a driving assembly connected to the traveling wheels. The driving assembly includes but is not limited to a driving motor. The driving motor is used to provide power to the traveling wheels to move the scooter 100 forward, backward, etc.

[0061] The steering mechanism 40 includes a steering gear and a steering rod, wherein the steering gear is arranged at the front end of the chassis 10, and the steering gear can drive the running wheels to steer; the steering rod is arranged at the front end of the chassis 10, and the steering rod extends along the third direction, and the bottom end of the steering rod is connected to the steering gear. The steering gear movement can be controlled by the steering rod to steer the running wheels.

[0062] like Figure 2 、 Figure 3 and Figure 4 As shown, the chassis 10 provided in the embodiment of the present application includes a first chassis frame 11 and a second chassis frame 12, wherein the first chassis frame 11 and the second chassis frame 12 are arranged adjacent to each other along a first horizontal direction, the first chassis frame 11 is slidably connected to the second chassis frame 12, and the first chassis frame 11 can slide relative to the second chassis frame 12, and the two are at least partially overlapped along the first direction.

[0063] For example, the first chassis frame 11 is slidably mounted on the second chassis frame 12 , and the second chassis frame 12 is fixed. The first chassis frame 11 moves relative to the second chassis frame 12 along a first horizontal direction. This embodiment of the present application is described as an example.

[0064] When the chassis 10 is in the folded state, the first chassis frame 11 slides onto the second chassis frame 12 and the two overlap each other. This arrangement can reduce the length of the chassis 10 in the first horizontal direction, so that the folded mobility scooter 100 takes up little space and is easy to carry.

[0065] When the chassis 10 is unfolded, the first chassis frame 11 moves relative to the second chassis frame 12 along a first horizontal direction to unfold the first chassis frame 11 and the second chassis frame 12. For example, the first chassis frame 11 and the second chassis frame 12 are arranged horizontally, and after unfolding, the first chassis frame 11 and the second chassis frame 12 are in the same plane.

[0066] It should be noted that when the chassis 10 is in the stowed state, the link folding mechanism 30 is in the folded state, that is, the mobility scooter 100 is in the folded state. When the chassis 10 is in the unfolded state, the link folding mechanism 30 is in the unfolded state, that is, the mobility scooter 100 is in the unfolded state.

[0067] The chassis 10 provided in the embodiment of the present application also includes a wire harness storage mechanism 60, which is disposed on the chassis 10 and connected to both the first chassis frame 11 and the second chassis frame 12. When the chassis 10 is in the stowed state, the wire harness storage mechanism 60 is located in a first preset position. When the chassis 10 is unfolded, the wire harness storage mechanism 60 moves in a first horizontal direction and to a second preset position. The cable harness is the electrical connection line of the mobility scooter, and multiple cable harnesses are distributed at the bottom of the chassis 10. The wire harness storage mechanism 60 is used to uniformly and orderly store the multiple cable harnesses to prevent the harnesses from becoming tangled.

[0068] like Figure 5 As shown, the wire harness storage mechanism 60 includes a wire harness box 61, which has a first end 611 and a second end 612 relative to each other along its length direction. The first end 611 is fixedly connected to the first chassis frame 11, and the second end 612 is fixedly connected to the second chassis frame 12.

[0069] The wire harness storage mechanism 60 also includes a wire harness, and the wire harness box 61 matches the wire harness to set the wire harness in the wire harness box 61, so that the wire harness box 61 can store the wire harness, protect the wire harness, and restrict the movement trajectory of the wire harness.

[0070] The wiring harness has a first connection end and a second connection end relative to each other along its length direction. The first connection end is fixedly connected to the first end 611 and the second connection end is fixedly connected to the second end 612 to ensure that the wiring harness box 61 can accommodate and protect the wiring harness.

[0071] During the folding process of the entire vehicle, the second end 612 of the wiring harness box 61 is pushed and moved along the first horizontal direction, and the wiring harness moves under the constraint of the wiring harness box 61. Since the wiring harness box 61 has a corresponding radius during movement and deformation, the push and pull forces on the wiring harness are minimized to the greatest extent, which can better protect the wiring harness.

[0072] Continue to refer Figure 5, the chassis 10 is in the unfolded state, the first chassis frame 11 slides to the first position, the first chassis frame 11 and the second chassis frame 12 are arranged horizontally, the first chassis frame 11 and the second chassis frame 12 are in the same plane, and the first chassis frame 11 and the second chassis frame 12 are adjacent; at this time, the first end 611 will move away from the second end 612 along the first horizontal direction.

[0073] refer to Figure 7 The chassis 10 is in the storage state, the first chassis frame 11 slides to the second position, the first chassis frame 11 and the second chassis frame 12 at least partially overlap, and the first chassis frame 11 slides onto the second chassis frame 12; at this time, the first end 611 will be close to the second end 612 along the first horizontal direction, and the wiring harness is also stored as the chassis 10 is stored.

[0074] In the embodiment of the present application, the wiring harness box 61 can be bent and deformed. The wiring harness box 61 includes a bending section 613. The bending section 613 has a preset bending radius, which can be set by those skilled in the art according to actual conditions.

[0075] When the first end 611 moves away from the second end 612 along the first horizontal direction, the bent section 613 moves closer to the first end 611. When the first end 611 moves closer to the second end 612 along the first horizontal direction, the bent section 613 moves away from the first end 611, and the straight section length of the wiring harness box 61 decreases.

[0076] refer to Figure 6 In this embodiment, the harness box 61 is a drag chain composed of multiple linked units. The drag chain has a receiving cavity in which the harness is placed. The harness is placed in the drag chain, protecting it from wear and tear, and preventing the harnesses from becoming entangled, worn, pulled apart, or becoming scattered.

[0077] The drag chain has a certain bending radius, the pitches between each unit in the drag chain are the same, and each unit can rotate freely. Those skilled in the art can set the bending radius of the drag chain according to actual conditions.

[0078] Continue to refer Figure 5 and Figure 7 In the embodiment of the present application, the wire harness storage mechanism 60 also includes a storage box 63, which is fixedly connected to the first chassis frame 11; the storage box 63 has a first through hole, and the first end 611 and the bending section 613 are both arranged in the storage box 63 from the first through hole.

[0079] The storage box 63 includes a first area and a second area, which are adjacent to each other along a first horizontal direction. The first area is close to the second chassis frame 12 , and the second area is far from the second chassis frame 12 .

[0080] When the first end 611 moves away from the second end 612 along the first horizontal direction, the bent section 613 is located in the first area inside the storage box 63; when the first end 611 moves closer to the second end 612 along the first horizontal direction, the bent section 613 is located in the second area inside the storage box 63.

[0081] The storage box 63 is used to uniformly and regularly store the wiring harness and the wiring harness box 61, thereby improving the aesthetics of the mobility scooter. At the same time, when the chassis 10 is in the stored state, the wiring harness and the wiring harness box 61 will not fall due to their own gravity. It can also prevent the wiring harness and the wiring harness box 61 from contacting other components during the storage or unfolding of the chassis 10, thereby improving the safety of the mobility scooter.

[0082] The storage box 63 is provided with a fixing position 631 , the first end 611 is fixedly connected to the fixing position 631 , and the fixing position 631 is located in the first area.

[0085] Continue to refer Figure 7 When the first end 611 approaches the second end 612 along the first horizontal direction, a portion of the bent section 613 extends out of the storage box 63 from the second through hole. When the chassis 10 is in the storage state, the bent section 613 is prevented from abutting against the inner wall of the storage box 63, protecting the wire harness and the wire harness box 61 from bending deformation.

[0086] Continue to refer Figure 7 In the embodiment of the present application, during the storage process of the chassis 10, the first end 611 will approach the second end 612 along the first horizontal direction; until the first chassis frame 11 slides to the second position, the storage of the chassis 10 is completed, and at this time the second end 612 is aligned with the first end 611 in the second horizontal direction.
