Description

Technical Field

[0002] Currently, foldable scooters can be folded when needed to reduce their size, making them easy to carry and store, and suitable for a variety of travel scenarios. For example, users can fold the foldable scooter and put it in public transportation, the office, or home, avoiding storage space restrictions and improving flexibility and convenience. In the related art, foldable scooters often have a rotating connection structure between the front and the frame or the rear and the frame to fold the scooter, and each folding position is folded once. In this way, the scooter can be folded only after multiple folding operations, resulting in low folding efficiency and complicated operation. At the same time, the folding scooters in the related art also have the problem of insufficient folding, large volume after folding, and poor folding effect. Utility Model Content

DETAILED DESCRIPTION

[0072] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0073] It should be understood that the terms "upper", "lower", "left", "right", "front", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0074] like Figures 1 to 3 As shown, an embodiment of the present invention provides a mobility scooter, comprising:

[0075] The load-bearing assembly 100 includes a load-bearing member 110 for passengers to sit on. In one embodiment, the load-bearing assembly 100 includes but is not limited to a seat assembly, a cargo device assembly, or a manipulator assembly.

[0076] The rear frame 200 , on which the load-bearing assembly 100 is rotatably mounted; the rear frame 200 is a rear support frame of the vehicle located at the rear of the mobility scooter and used to fix the load-bearing assembly 100 .

[0077] The front frame 300 is rotatably connected to the rear frame 200; the front frame 300 is the front support frame of the vehicle located at the front of the mobility scooter and used to mount and secure the front end 410. The front frame 300 and rear frame 200 are rotatably connected to each other to enable foldability. In some embodiments, a fixed stop assembly (such as a snap assembly) is provided between the front frame 300 and rear frame 200 to limit the relative rotation between the two after folding or unfolding. This prevents relative rotation in the fully folded position, which could result in poor folding performance, and also prevents relative rotation in the fully unfolded position, which could pose a hazard during travel.

[0078] The front assembly 400 is rotatably mounted on the front frame 300 at one end away from the rear frame 200; the front assembly 400 includes a front 410 for passengers to drive and control the scooter. Figure 1 As shown, from the front of the scooter 410 to the direction of the carrier 110, "front" refers to the direction close to the front of the scooter 410 (i.e. Figure 1 ), “rear” refers to the direction close to the carrier 110 (i.e. Figure 1 to the right of the center).

[0079] The folding device 500 is connected to the load-bearing assembly 100, the rear frame 200, the front assembly 400 and the front frame 300. The folding assembly 500 can be connected between the load-bearing assembly 100, the rear frame 200, the front assembly 400 and the front frame 300, and drive the load-bearing assembly 100, the rear frame 200, the front assembly 400 and the front frame 300 to rotate relative to each other to achieve folding or unfolding. Specifically, when the front frame 300 rotates in a first direction relative to the rear frame 200, the folding device 500 drives the load-bearing assembly 100 to rotate in the first direction relative to the rear frame 200, and simultaneously drives the head assembly 400 to rotate in a second direction relative to the front frame 300, so as to synchronously realize the folding or unfolding of the load-bearing assembly 100, the rear frame 200, the front frame 300 and the head assembly 400, wherein the first direction is opposite to the second direction.

[0080] like Figure 2 and Figure 3As shown, in this embodiment, the mobility scooter can be folded or unfolded when needed. When the mobility scooter needs to be folded, the front frame 300 can be rotated counterclockwise relative to the rear frame 200, thereby folding the front frame 300 and the rear frame 200 together. While the front frame 300 and the rear frame 200 are folding together, the front frame 300 also drives the support assembly 100 to rotate counterclockwise relative to the rear frame 200 via the folding device 500, thereby folding the support assembly 100 and the rear frame 200 together. In addition, the rear frame 200 also drives the head assembly 400 to rotate clockwise relative to the front frame 300 via the folding device 500, thereby folding the head assembly 400 and the front frame 300 together. During the folding process, the front frame 300 and the carrying assembly 100 are respectively located at the two ends of the rear frame 200 and rotate counterclockwise relative to the rear frame 200. At the same time, the rear frame 200 and the head assembly 400 are also respectively located at the two ends of the front frame 300 and rotate clockwise relative to the front frame 300, so that the head assembly 400 and the rear frame 200 are folded at the opposite ends of the front frame 300, and the front frame 200 is folded at the opposite ends of the front frame 300. The front frame 300 and the carrying assembly 100 are respectively folded at opposite ends of the rear frame 200, that is, the front assembly 400, the front frame 300, the rear frame 200 and the carrying assembly 100 are folded in a W-shape, so that the mobility scooter can be fully folded. In addition, the front assembly 400, the front frame 300, the rear frame 200 and the carrying assembly 100 do not interfere with each other, thereby reducing the volume of the folded mobility scooter and improving the folding effect.

[0081] When the mobility scooter needs to be unfolded, the front frame 300 can be rotated clockwise relative to the rear frame 200, thereby unfolding the front frame 300 and the rear frame 200. While the front frame 300 and the rear frame 200 are unfolding, the front frame 300 also drives the support assembly 100 to rotate clockwise relative to the rear frame 200 via the folding device 500, thereby unfolding the support assembly 100 and the rear frame 200. Furthermore, the rear frame 200 also drives the front assembly 400 to rotate counterclockwise relative to the front frame 300 via the folding device 500, thereby unfolding the front assembly 400 and the front frame 300. During the above deployment process, the front frame 300 and the load-bearing assembly 100 are respectively located at the two ends of the rear frame 200 and rotate clockwise relative to the rear frame 200. At the same time, the rear frame 200 and the head assembly 400 are also respectively located at the two ends of the front frame 300 and rotate counterclockwise relative to the front frame 300. Therefore, the head assembly 400, the front frame 300, the rear frame 200 and the load-bearing assembly 100 can be deployed simultaneously without interfering with each other.

[0082] It is understood that the first direction in this embodiment can be clockwise or counterclockwise. When the front frame 300 rotates in the first direction relative to the rear frame 200, the rear frame 200 also rotates in the second direction relative to the front frame 300. When deployed, the rear frame 200 and the front frame 300 are substantially coplanar, ensuring the flatness of the scooter during use, making it easier for the user to rest their feet while driving. The front frame 300 or the rear frame 200 may have a hollow structure so that part or all of the folding device 500 can be installed inside the rear frame 200, thereby preventing the folding device 500 from being completely exposed outside the front frame 300 or the rear frame 200, thereby affecting the flatness and aesthetics of the front frame 300 or the rear frame 200, and also preventing damage thereto. At the same time, the hollow structure of the front frame 300 can also allow the head 410 assembly to be stored inside the front frame 300 when folded, and the hollow structure of the rear frame 200 can also allow the bearing assembly 100 to be stored inside the rear frame 200 when folded, thereby reducing the volume of the scooter after folding.

[0083] like Figure 1 、 Figure 4 and Figure 5As shown, further, the rotation axis rotatably connected between the rear frame 200 and the front frame 300 is a first rotation axis a; the head assembly 400, the front frame 300, the rear frame 200, the load-bearing assembly 100 and the folding device 500 are all symmetrical structures, and in a specific embodiment, the head assembly 400, the front frame 300, the rear frame 200, the load-bearing assembly 100 and the folding device 500 are all symmetrically arranged with respect to the same reference symmetry plane, which is perpendicular to the above-mentioned first rotation axis and passes through the center point of the first rotation axis a (the center point of the first rotation axis a refers to the center position point between the two intersection points located at the outermost positions of both ends of all intersection points between the first rotation axis a and the front frame 300 or the rear frame 200). It can be understood that in some embodiments, the front assembly 400, the front frame 300, the rear frame 200, the load-bearing assembly 100 and the folding device 500 can also be arranged symmetrically with respect to different reference planes, but the above-mentioned different reference planes also need to be roughly on the same plane to ensure that the transmission of rotational motion between the front assembly 400, the front frame 300, the rear frame 200, the load-bearing assembly 100 and the folding device 500 is smooth without jamming or interference, and the above-mentioned arrangement can enable the mobility scooter to maintain balance while driving.

[0084] Furthermore, the folding mechanism may be a multi-link structure, so that the front assembly 400 can be folded or unfolded relative to the front frame 300, and the support assembly 100 can be folded or unfolded relative to the rear frame 200 through the mutual transmission of motion between the multi-links.

[0085] Furthermore, the rotation axis connecting the front assembly 400 and the front frame 300 is the second rotation axis b, and the rotation axis connecting the support assembly 100 and the rear frame 200 is the third rotation axis c. It is understood that the first rotation axis a, the second rotation axis b, and the third rotation axis c can be arranged in parallel, so that the front assembly 400, the front frame 300, the rear frame 200, and the support assembly 100 are all roughly located on the projection surface of the front frame 300 or the rear frame 200 after folding, thereby reducing the maximum projection area of the folded mobility scooter and making the mobility scooter easier to store. The first rotation axis a may be located at the end edges of the front frame 300 and the rear frame 200 (e.g., the bottom edge of the connection end between the front frame 300 and the rear frame 200), so that the front frame 300 can be fully folded relative to the rear frame 200 (i.e., the rotation angle can be close to 180 degrees) without interference between the front frame 300 and the rear frame 200 during the rotation process.

[0086] In the above embodiment of the present invention, the head assembly 400, the front frame 300, the rear frame 200 and the carrying assembly 100 are respectively connected through the folding device 500. When the front frame 300 rotates in a first direction relative to the rear frame 200, the front frame 300 drives the carrying assembly 100 to rotate in the first direction relative to the rear frame 200 through the folding device 500, and at the same time drives the head assembly 400 to rotate in the second direction relative to the front frame 300. Therefore, while the rear frame 200 and the front frame 300 are folded or unfolded, the head assembly 400 and the front frame 300 are folded or unfolded, and the carrying assembly 100 and the rear frame 200 are folded or unfolded. In the present invention, folding or unfolding multiple components only requires one operation, that is, one folding process can simultaneously achieve the folding of the front assembly 400, the front frame 300, the rear frame 200 and the carrying assembly 100; one unfolding process can simultaneously achieve the unfolding of the front assembly 400, the front frame 300, the rear frame 200 and the carrying assembly 100; its operation is simple and improves the folding efficiency. In addition, in the present invention, the front frame 300 and the load-bearing assembly 100 are arranged at both ends of the rear frame 200, and the head assembly 400 and the rear frame 200 are arranged at both ends of the front frame 300. During the folding process, the front frame 300 and the load-bearing assembly 100 can rotate in the same direction relative to the rear frame 200 at both ends of the rear frame 200, and the head assembly 400 and the rear frame 200 can rotate in the same direction relative to the front frame 300 at both ends of the front frame 300, so that the head assembly 400, the front frame 300, the rear frame 200 and the load-bearing assembly 100 are folded in a W shape to achieve full folding of the mobility scooter, and the head assembly 400, the front frame 300, the rear frame 200 and the load-bearing assembly 100 will not interfere with each other, thereby reducing the volume of the folded mobility scooter and improving the folding effect.

[0087] like Figure 1 As shown, in one embodiment, the vehicle head assembly 400 includes a vehicle head 410 and a steering mechanism 420; the steering mechanism 420 includes a mounting seat 421 and a steering assembly 422 mounted in the mounting seat 421; the mounting seat 421 is rotatably connected to the front frame 300; the vehicle head 410 is connected to the steering assembly 422. It can be understood that the steering assembly 422 is mounted in the mounting seat 421 and can rotate relative to the mounting seat 421 without relative displacement with the mounting seat. Figure 1 As shown, the rotation axis rotatably connected between the mounting seat 421 and the front frame 300 is also the second rotation axis b.

[0088] like Figure 1As shown, in one embodiment, the mobility scooter further includes a first wheel set 600 connected to the end of the steering assembly 422 away from the front frame 410, and a second wheel set 700 mounted on the rear frame 200 away from the front frame 300. It is understood that the steering assembly 422 has opposite ends connected to the front frame 410 and the first wheel set 600, respectively, and the steering assembly 422 is rotatable relative to the mounting base 421. Therefore, the front frame 410 can control the steering of the first wheel set 600 by controlling the steering assembly 422 to rotate within the mounting base 421. The front frame assembly 400 (i.e., the first wheel set 600) is located on the end of the front frame 300 away from the rear frame 200, and the second wheel set 700 is located on the end of the rear frame 200 away from the front frame 300. Therefore, the second wheel set 700 and the first wheel set 600 can work together to stably support the mobility scooter on the ground and prevent it from tipping over. In one embodiment, the rotation axis of the rotational connection between the steering assembly 422 and the mounting seat 421 is perpendicular to the second rotation axis b, thereby facilitating the steering of the first wheel assembly 600 through the vehicle head 410 .

[0089] like Figure 1 As shown, in one embodiment, the front assembly 400 further includes a retractable column 430, and the front 410 is connected to the steering assembly 422 via the retractable column 430. It is understandable that the retractable column 430 can be retracted to lengthen or shorten. In this way, when the mobility scooter is in use, the retractable column 430 can be extended to adjust the front 410 to the height required by the user. When the mobility scooter is folded, the retractable column 430 can be shortened to lower the height of the front 410, thereby making it easier for the front 410 to be stored in the front frame 300, thereby reducing the volume of the scooter after folding.

[0090] like Figure 1As shown, in one embodiment, the telescopic column 430 includes a first column 431, a second column 432, and a pipe clamp 433. One end of the first column 431 is connected to the steering assembly 422, the other end of the first column 431 is slidably connected to the second column 432, and the end of the second column 432 away from the first column 431 is connected to the front of the vehicle 410. The pipe clamp 433 is disposed between the first column 431 and the second column 432 and is used to clamp the first column 431 and the second column 432. It is understood that the cross-sectional shape of the first column 431 or the cross-sectional shape of the second column 432 can be circular, rectangular, or other shapes, as long as the first column 431 can be slidably connected to the second column 432 to enable the telescopic column 430 to be telescopic. The first column 431 can be slidably connected to the second column 432 by being inserted into the second column 432. The first column 431 can also be slidably connected to the second column 432 by other snap-on sliding methods (for example, providing a slider on the first column 431 and a sliding groove matching the slider on the second column 432). The pipe clamp 433 is used to lock the sliding connection between the first column 431 and the second column 432 when needed, thereby converting the sliding connection between the first column 431 and the second column 432 into a fixed connection, so that the user can use the mobility scooter.

[0091] In one embodiment, the mounting base 421 is provided with a mounting hole (not shown), into which the steering assembly 422 is mounted, and the first column 431 is connected to the steering assembly 422 mounted within the mounting hole. A sliding hole (not shown) is provided on the end of the first column 431 proximal to the vehicle head 410, into which the end of the second column 432 distal to the vehicle head 410 slides. It is understood that the mounting hole and the steering assembly 422 mate with each other, allowing the steering assembly 422 to rotate within the mounting hole. It is understood that the steering assembly 422 includes a motor for driving the first wheel assembly 600 and / or the second wheel assembly 700, as well as mounting components, such as bearings and flanges, for mounting the first column 420 and the first wheel assembly 600 to enable relative rotation between the mounting base 421, the first column 431, and the first wheel assembly 600. These components are not further described here.

[0092] like Figure 1 As shown, in one embodiment, the vehicle head assembly 400 further includes a display device 440 mounted on the vehicle head 410 and configured to display vehicle information and operating information. The display device 440 can be used to display vehicle information and operating information. A user can also perform operations such as issuing commands on the display device 440 by touching the display device 440.

[0093] In one embodiment, the front assembly 400 further includes a camera device 450 mounted on the front 410 and configured to capture images of the surrounding environment of the mobility scooter. The camera device 450 can be used to identify roads, obstacles, or traffic signals, etc., to analyze the surrounding environment. Furthermore, the camera device 450 can be used to plan an optimal driving path based on the surrounding environment using an onboard computer or other device. This improves the autonomous navigation capabilities of the mobility scooter in complex or congested traffic environments, thereby enabling autonomous driving of the mobility scooter.

[0094] In one embodiment, the front assembly 400 further includes a first radar 460 mounted on the front 410 and configured to identify objects in front of the mobility scooter. The first radar 460 includes, but is not limited to, one or more of a millimeter-wave radar, a laser radar, or an ultrasonic radar. The first radar 460 can detect objects in front of the mobility scooter (including other vehicles, pedestrians, and obstacles, etc.) and calculate a safe distance based on radar signals generated by the detected objects using an onboard computer or other device. This allows the first radar 460 to automatically adjust the mobility scooter's speed or initiate emergency braking to avoid collisions, thereby improving the scooter's driving safety.

[0095] In one embodiment, the vehicle head assembly 400 further includes a lighting lamp 470 mounted on the vehicle head 410 for illumination. The lighting lamp 470 includes, but is not limited to, one or more of an LED (Light Emitting Diode) lamp, a laser lamp, or a halogen lamp.

[0096] In one embodiment, the vehicle head assembly 400 further includes a speed regulator 480 mounted on the vehicle head 410 and configured to adjust the vehicle speed. It is understood that the vehicle head assembly 400 may include one or more of the display device 440, the camera device 450, the first radar 460, the lighting 470, or the speed regulator 480.

[0097] like Figure 1As shown, in one embodiment, the mobility scooter further includes a second radar 800 mounted on the rear frame 200 and configured to identify objects behind the mobility scooter. The second radar 800 includes, but is not limited to, one or more of a millimeter-wave radar, a laser radar, or an ultrasonic radar. The second radar 800 can detect objects behind the mobility scooter (including other vehicles, pedestrians, and obstacles), or work with the first radar 460 to detect objects in front of and behind the mobility scooter. The second radar 800 then calculates a safe distance based on radar signals generated by detecting objects using an onboard computer or other device. This allows the vehicle to automatically adjust its speed or initiate emergency braking to avoid collisions, thereby improving the vehicle's driving safety.

[0098] In one embodiment, the mobility scooter further includes an ultra-wideband transmitter for positioning, which is mounted on the front frame 300. The ultra-wideband transmitter can implement precise navigation and location services, such as automatic parking, vehicle tracking, and indoor positioning.

[0099] In one embodiment, the mobility scooter further includes a wireless communication component for transmitting and receiving wireless communication signals. The wireless communication component may be mounted on the front frame 300, the rear frame 200, the head assembly 400, or the load-bearing assembly 100. The wireless communication component can wirelessly connect to a user's mobile device, thereby enabling functions such as data synchronization, remote control, and intelligent anti-theft. It is understood that the mobility scooter may include one or more of the second radar 800, the ultra-wideband transmitter, and the wireless communication component.

[0100] like Figure 1 and Figure 4 As shown, in one embodiment, the folding device 500 includes a first folding mechanism 510; the first folding mechanism 510 includes a first active rod 511, a first connecting rod 512 and a first connecting rod assembly 513 rotatably mounted on the rear frame 200; the first connecting rod 512 is rotatably connected between the first connecting rod assembly 513 and the load-bearing assembly 100; one end of the first active rod 511 is rotatably mounted on the front frame 300, and the other end of the first active rod 511 is rotatably connected to an end of the first connecting rod assembly 513 away from the first connecting rod 512; when the front frame 300 rotates in a first direction relative to the rear frame 200, the front frame 300 drives the first connecting rod assembly 513 to swing in the first direction through the first active rod 511, and then drives the load-bearing assembly 100 to rotate in the first direction relative to the rear frame 200 through the first connecting rod 512.

[0101] It is understood that part or all of the first folding mechanism 510 can be installed inside the rear frame 200. The first connecting rod 512 is rotatably connected between the first link assembly 513 and the load-bearing assembly 100. The connection between the first connecting rod 512 and the load-bearing assembly 100 allows the load-bearing assembly 100 to rotate in the same direction as the first link assembly 513. The shape and size of the first link assembly 513 and the first connecting rod 512 can be adjusted according to actual conditions, as long as the first link assembly 513 and the first connecting rod 512 can drive the load-bearing assembly 100 and the load-bearing member 110 to fully fold synchronously with the rear frame 200 when the front frame 300 and the rear frame 200 are folded or unfolded. The first active rod 511 can be used to control the relative position of the front frame 300 and the first link assembly 513 when the front frame 300 and the rear frame 200 are fully folded or unfolded, thereby preventing interference between the front frame 300 and the first link assembly 513. The rotational axis connecting the first connecting rod 512 and the first link assembly 513 is the fourth rotational axis; the rotational axis connecting the first connecting rod 512 and the load-bearing assembly 100 is the fifth rotational axis; and the rotational axis connecting the first link assembly 513 and the rear frame 200 is the sixth rotational axis. The fourth, fifth, and sixth rotational axes are parallel to each other, allowing rotational motion to be transmitted to each other without interference. Furthermore, the first rotational axis a, the second rotational axis b, the third rotational axis c, the fourth rotational axis, the fifth rotational axis, and the sixth rotational axis are all arranged in parallel.

[0102] like Figure 1 and Figure 4 As shown, in one embodiment, the first connecting rod assembly 513 includes:

[0103] The first connecting rod 5131 is rotatably mounted on the rear frame 200. In this embodiment, the first connecting rod assembly 513 is a multi-link structure, wherein the rear frame 200 can be used as a frame structure of the first connecting rod assembly 513. The first connecting rod 5131 serves as a crank structure in the first connecting rod assembly 513 and is rotatably connected to the rear frame 200.

[0104] The second connecting rod 5132 has one end rotatably mounted on the rear frame 200, and the other end of the second connecting rod 5132 is rotatably connected to the first connecting rod 512; that is, the second connecting rod 5132 also serves as a crank structure in the first connecting rod assembly 513 and is rotatably connected to the rear frame 200.

[0105] The third link 5133 is rotationally connected between the first link 5131 and the second link 5132; that is, the third link 5133 serves as a link structure, which is rotationally connected to the first link 5131 and the second link 5132 respectively to transmit the rotational motion of the first link 5131 to the second link 5132.

[0106] One end of the first active rod 511 away from the front frame 300 is rotatably connected to a first hinge point; the first hinge point refers to the rotation connection point between the first link 5131 and the third link 5133; when the front frame 300 rotates in a first direction relative to the rear frame 200, the front frame 300 drives the first link 5131 and the second link 5132 to swing in the first direction relative to the rear frame 200 through the first active rod 511, and then drives the bearing assembly 100 to rotate in the first direction relative to the rear frame 200 through the first connecting rod 512.

[0107] It is understood that the rotation axis of the rotational connection between the first link 5131 and the rear frame 200, the rotation axis of the rotational connection between the second link 5132 and the rear frame 200, the rotation axis of the rotational connection between the first link 5131 and the third link 5133, and the rotation axis of the rotational connection between the second link 5132 and the third link 5133 can be arranged parallel to each other. This prevents interference between the first link assemblies 513 during the mutual transmission of rotational motion. In this embodiment, the rotation axis of the rotational connection between the first link 5131 and the rear frame 200 and the rotation axis of the rotational connection between the second link 5132 and the rear frame 200 are arranged parallel to each other and are both part of the sixth rotation axis. The lengths of the first link 5131, the second link 5132, or the third link 5133, as well as the distance between the two rotation axes of the sixth rotation axis, can be set according to actual conditions, as long as the first link assembly 513 can swing when the front frame 300 and the rear frame 200 are folded, driving the first connecting rod 512 to move, thereby driving the bearing assembly 100 and the bearing member 110 to fold synchronously with the rear frame 200. The first active rod 511 is rotatably connected between the front frame 300 and the first hinge point, so that the entire first link assembly 513 can rotate with the front frame 300 and in the same direction as the front frame 300. Furthermore, the front frame 300 can achieve linkage with the first link assembly 513 through the configuration of the first active rod 511. The length of the first active rod 511 can be set according to actual conditions, as long as the first active rod 511 can drive the first connecting rod assembly 513 to swing along with the front frame 300 during the folding process of the front frame 300 and the rear frame 200, and then drive the bearing assembly 100 and the bearing member 110 to rotate synchronously through the first connecting rod 512, so as to achieve full folding between the bearing member 110, the rear frame 200, and the front frame 300.

[0108] In one embodiment, the length of the third link 5133 is greater than or equal to the length of the first link 5131 and the second link 5132, thereby ensuring that the rotational motion over a longer distance can be transmitted between the first link 5131 and the second link 5132 through the third link 5133, while also ensuring that the length of the rear frame 200 is longer to meet the comfort requirements of the mobility scooter.

[0109] like Figure 1 and Figure 4As shown, in one embodiment, the mobility scooter further includes a support wheel 900; the folding device 500 further includes a support and folding assembly 520; the support and folding assembly 520 includes a third connecting rod 521, a tenth connecting rod 522 and an eleventh connecting rod 523; the third connecting rod 521 is mounted on the rear frame 200; the tenth connecting rod 522 is rotatably connected between the first connecting rod assembly 513 and the eleventh connecting rod 523; the end of the third connecting rod 521 away from the rear frame 200 is rotatably connected to the eleventh connecting rod 523, and the support wheel 900 is rotatably mounted on the end of the eleventh connecting rod 523 away from the tenth connecting rod 522.

[0110] In this embodiment, the tenth link 522 and the support wheel 900 are respectively located at opposite ends of the eleventh link 523, so that when the first link assembly 513 rotates relative to the rear frame 200, the support wheel 900 is driven to rotate in the same rotation direction as the first link assembly 513 via the tenth link 522, the eleventh link 523, and the third connecting rod 521. It can be understood that the rotation axis of the rotational connection between the tenth link 522 and the first link assembly 513, the rotation axis of the rotational connection between the tenth link 522 and the eleventh link 523, and the rotation axis of the rotational connection between the third connecting rod 521 and the eleventh link 523 are all parallel to each other, so that rotational motion can be transmitted to each other without interference. The length and shape of the third connecting rod 521, the tenth connecting rod 522 or the eleventh connecting rod 523 can be set according to actual conditions, so that when the front frame 300 and the rear frame 200 are fully folded, the support wheel 900 can rotate to a preset support angle to support the mobility scooter.

[0111] like Figure 1 and Figure 4 As shown, in one embodiment, the support assembly 100 includes a support member 110 and a support folding mechanism 120 for mounting the support member 110; when the front frame 300 rotates in a first direction relative to the rear frame 200, the support folding mechanism 120 and the support member 110 mounted on the support folding mechanism 120 are driven to rotate in the first direction relative to the rear frame 200 via the folding device 500. It is understandable that the support member 110 can be mounted on an end of the support folding mechanism 120 away from the rear frame 200. The first rotation axis a, the second rotation axis b, and the third rotation axis c can be a single axis, or can include multiple parallel axes; for example, Figure 1 The first rotation axis a and the second rotation axis b shown in FIG are separate axes, and Figure 1 The third rotation axis c shown in FIG is composed of at least two axes parallel to each other.

[0112] like Figure 1 and Figure 4 As shown, in one embodiment, the carrying and folding mechanism 120 includes:

[0113] The fourth connecting rod 121 is used to mount the supporting member 110 ; the supporting member 110 is fixedly mounted on the fourth connecting rod 121 .

[0114] The fifth link 122 has one end rotatably mounted on the rear frame 200, and the other end of the fifth link 122 is rotatably connected to the fourth link 121; the end of the folding device 500 away from the front frame 300 is rotatably connected to the fifth link 122; in this embodiment, the supporting folding mechanism 120 is also a multi-link structure, wherein the rear frame 200 is used as a frame structure for supporting the folding mechanism 120; the fifth link 122 is rotatably connected to the rear frame 200 as a rocker structure.

[0115] The sixth link 123; one end of the sixth link 123 is rotatably mounted on the rear frame 200, and the other end of the sixth link 123 is rotatably connected to the fourth link 121; that is, the sixth link 123 also serves as a rocker structure and is rotatably connected to the rear frame 200; the fourth link 121 serves as a link structure and is rotatably connected to the fifth link 122 and the sixth link 123, respectively, so that the fifth link 122 and the sixth link 123 rotate synchronously.

[0116] When the front frame 300 rotates in the first direction relative to the rear frame 200, the folding device 500 drives the fifth link 122 and the sixth link 123 to swing in the first direction relative to the rear frame 200. It can be understood that the front frame 300 drives the fifth link 122 and the sixth link 123 to swing in the first direction relative to the rear frame 200 via the folding device 500, which can drive the bearing member 110 mounted on the fourth link 121 to move closer to (when the first direction is counterclockwise) or farther away from (when the first direction is clockwise) the rear frame 200.

[0117] In this embodiment, the rotation axis of the fifth link 122 and the rear frame 200 is connected in rotation, and the rotation axis of the sixth link 123 and the rear frame 200 is connected in rotation in parallel, and both are Figure 4The rotation axis of the rotational connection between the fifth link 122 and the fourth link 121, and the rotation axis of the rotational connection between the sixth link 123 and the fourth link 121 are also arranged parallel to the third rotation axis c. In this way, the support assembly 100 will not interfere with each other during the process of transmitting rotational motion to each other. The length of the fourth link 121, the fifth link 122, or the sixth link 123, as well as the distance between the two rotation axes in the third rotation axis c, can be set according to actual conditions, as long as the height requirements of the support member 110 are met. At the same time, when the front frame 300 and the rear frame 200 are folded, the support member 110 and the rear frame 200 can be folded synchronously through the support assembly 100. The fifth link 122 and the sixth link 123 may be parallel to each other or not, and the first line between the upper end point of the fifth link 122 and the upper end point of the sixth link 123, and the second line between the lower end point of the fifth link 122 and the lower end point of the sixth link 123 may also be parallel to each other or not. In a preferred embodiment, Figure 4 As shown, the fifth link 122 and the sixth link 123 are equal and parallel to each other, and the first connecting line and the second connecting line are equal and parallel to each other. At this time, the load-bearing folding mechanism 120 is a parallelogram connecting rod mechanism. At this time, when the fifth link 122 and the sixth link 123 swing in the same direction relative to the rear frame 200, the upper surface of the fourth link 121 can remain basically parallel to the front frame 300. In this way, after folding, the support member 110 installed on the upper surface of the fourth link 121 is also basically parallel to the front frame 300 without a large angle. In this way, there will be no large folding gap between the support member 110 and the front frame 300 after folding, thereby reducing the volume after folding.

[0118] like Figure 1 and Figure 4 As shown, in one embodiment, the carrying assembly 100 further includes a battery compartment 130 mounted on the fourth connecting rod 121. It is understandable that the battery compartment 130 can be used to store batteries to provide power to the display device 440, the camera device 450, the first radar 460, the lighting 470, the speed regulator 480, the second radar 800, the ultra-wideband transmitter, or the wireless communication component.

[0119] In one embodiment, the supporting assembly 100 further includes a tail light 140 mounted on the fourth connecting rod 121. The tail light 140 includes but is not limited to one or more of an LED light, a laser light, or a halogen light.

[0120] like Figure 1 and Figure 5 As shown, in one embodiment, the folding device 500 includes a second folding mechanism 530; the second folding mechanism 530 includes a second active rod 531, a second connecting rod 532 and a second connecting rod assembly 533 rotatably mounted on the front frame 300, the second connecting rod 532 is rotatably connected between the second connecting rod assembly 533 and the head assembly 400; one end of the second active rod 531 is rotatably mounted on the rear frame 200, and the other end of the second active rod 531 is rotatably connected to the end of the second connecting rod 533 away from the second connecting rod 532; when the front frame 300 rotates in a first direction relative to the rear frame 200, the rear frame 200 drives the second connecting rod assembly 533 to swing in a second direction relative to the front frame 300 through the second active rod 531, and then drives the head assembly 400 to rotate in the second direction relative to the front frame 300 through the second connecting rod 532.

[0121] It will be appreciated that the second active rod 531 can be used to define the relative position of the rear frame 200 and the second link assembly 533 when the front frame 300 and the rear frame 200 are fully folded or unfolded, thereby preventing interference between the rear frame 200 and the second link assembly 533. Part or all of the second folding mechanism 530 can be mounted within the front frame 300. The second connecting rod 532 is rotatably connected between the second link assembly 533 and the head assembly 400. The connection defined by the second connecting rod 532 allows the head assembly 400 to rotate in the same direction as the second link assembly 533. The shape and size of the second link assembly 533 and the second connecting rod 532 can be customized to suit specific needs, as long as the second link assembly 533 and the second connecting rod 532 can drive the head assembly 400 to fully fold synchronously with the front frame 300 when the front frame 300 and the rear frame 200 are folded. In one embodiment, the seventh rotation axis rotatably connected between the second connecting rod assembly 533 and the front frame 300 and the first rotation axis a rotatably connected between the head assembly 400 and the front frame 300 are parallel to each other, thereby allowing the head assembly 400, the front frame 300, the rear frame 200 and the supporting assembly 100 to transmit rotational motion to each other without interference.

[0122] like Figure 1 and Figure 5 As shown, in one embodiment, the second connecting rod assembly 533 includes:

[0123] The seventh connecting rod 5331 has one end rotatably mounted on the front frame 300, and the other end of the seventh connecting rod 5331 is rotatably connected to the second connecting rod 532. In this embodiment, the second connecting rod assembly 533 is a multi-link structure, wherein the front frame 300 is used as the frame structure of the second connecting rod assembly 533. The seventh connecting rod 5331 is rotatably connected to the front frame 300 as the crank structure of the second connecting rod assembly 533.

[0124] The eighth connecting rod 5332 is rotatably mounted on the front frame 300 ; that is, the eighth connecting rod 5332 is rotatably connected to the front frame 300 as a crank structure of the second connecting rod assembly 533 .

[0125] The ninth connecting rod 5333 is rotationally connected between the seventh connecting rod 5331 and the eighth connecting rod 5332; the ninth connecting rod 5333 serves as a connecting rod structure, and is rotationally connected to the seventh connecting rod 5331 and the eighth connecting rod 5332 respectively, so as to transmit the rotational motion of the eighth connecting rod 5332 to the seventh connecting rod 5331.

[0126] One end of the second active rod 531 away from the rear frame 200 is rotatably connected to a second hinge point; the second hinge point refers to the rotation connection point between the eighth link 5332 and the ninth link 5333; when the front frame 300 rotates in a first direction relative to the rear frame 200, the rear frame 200 drives the seventh link 5331 and the eighth link 5332 relative to the front frame 300 in a second direction via the second active rod 531, and then drives the front assembly 400 to rotate in the second direction relative to the front frame 300 via the second connecting rod 532.

[0127] It will be appreciated that the rotational axes between the second connecting rod 532 and the second connecting rod assembly 533, the rotational axes corresponding to the hinge points between the links in the second connecting rod assembly 533, and the rotational axis of the rotational connection between the second connecting rod 532 and the head assembly 400 are all parallel to each other, thereby enabling the transmission of rotational motion between them without interference. In this embodiment, the rotational axis of the rotational connection between the seventh connecting rod 5331 and the front frame 300, and the rotational axis of the rotational connection between the eighth connecting rod 5332 and the front frame 300 are arranged in parallel and both are part of the seventh rotational axis. The rotational axes of the rotational connection between the seventh connecting rod 5331 and the ninth connecting rod 5333, and the rotational axes of the rotational connection between the eighth connecting rod 5332 and the ninth connecting rod 5333 are also parallel to the seventh rotational axis, thereby enabling the transmission of rotational motion between them without interference. The lengths of the seventh link 5331, the eighth link 5332, or the ninth link 5333, as well as the distance between the two seventh rotation axes, can be set according to actual conditions, so that during the folding process of the front frame 300 and the rear frame 200, the second connecting rod 532 and the front assembly 400 can be driven to be fully folded synchronously with the front frame 300 by the swinging of the second link assembly 533.

[0128] In one embodiment, the length of the ninth link 5333 is greater than or equal to the length of the seventh link 5331 and the eighth link 5332. This ensures that rotational motion over a relatively long distance can be transmitted between the seventh link 5331 and the eighth link 5332 via the ninth link 5333, while also ensuring that the front frame 300 is relatively long to meet the comfort requirements of the mobility scooter. The second active link 531 is rotatably connected between the rear frame 200 and the second hinge point, allowing the entire second link assembly 533 to rotate in the same direction as the rear frame 200. Furthermore, the rear frame 200 can be linked to the second link assembly 533 through the provision of the second active link 531. Furthermore, the third rotation axis c, the rotation axis of the rotational connection between the second active rod 531 and the rear frame 200, and the rotation axis of the rotational connection between the second active rod 531 and the second hinge point are parallel to each other, thereby allowing the transmission of rotational motion between the rear frame 200 and the second connecting rod assembly 533 to proceed smoothly without interference. The length of the second active rod 531 can be set according to actual conditions, as long as the second active rod 531 can drive the second connecting rod assembly 533 to swing with the rear frame 200 during the folding process of the front frame 300 and the rear frame 200, thereby driving the front assembly 400 and the front 410 to rotate synchronously via the second connecting rod 532, thereby achieving full folding of the front 410, the front frame 300, and the rear frame 200.

[0129] like Figure 1 and 6 As shown in the figure, in one embodiment, the folding device 500 further includes a drive assembly 540; the drive assembly 540 is connected between the rear frame 200 and the front frame 300 and is configured to drive the front frame 300 to rotate relative to the rear frame 200. It is understood that the drive assembly 540 can drive the front frame 300 to rotate relative to the rear frame 200, thereby achieving folding or unfolding of the head assembly 400, the front frame 300, the rear frame 200, and the supporting assembly 100 through the connection relationship between the various mechanisms in the above embodiments. The drive assembly 540 can be a telescopic cylinder or a rotary motor disposed between the rear frame 200 and the front frame 300, as long as it can drive the front frame 300 to rotate relative to the rear frame 200.

[0130] In this embodiment, by providing a single drive assembly 540 connected between the rear frame 200 and the front frame 300, the folding or unfolding of the head assembly 400, front frame 300, rear frame 200, and support assembly 100 of the mobility scooter can be automatically completed at one time, avoiding the need to provide multiple drive elements at multiple folding positions for multiple folding operations, thereby reducing costs while improving the convenience of the mobility scooter. The drive assembly 540 of the present invention can realize intelligent folding and unfolding of the mobility scooter. Utilizing the driving force of the drive member 541, the mobility scooter can be folded or unfolded with one click, making it more convenient for the user to use. There is no need to manually perform complex folding steps, making motion control simpler and easier for users with limited mobility to operate.

[0131] like Figure 1 and Figure 6 As shown, in one embodiment, the driving assembly 540 includes a driving member 541, a twelfth connecting rod 542 and a bending rod 543; the driving member 541 includes a fixed end 5411 and a driving end 5412; the fixed end 5411 is fixedly mounted on the rear frame 200, and the bending rod 543 is rotatably connected between the front frame 300 and the driving end 5412; one end of the twelfth connecting rod 542 is rotatably mounted on the rear frame 200, and the other end of the twelfth connecting rod 542 is rotatably connected to the bending rod 543; the driving end 5412 is used to drive the bending rod 543 and the twelfth connecting rod 542 to drive the front frame 300 to rotate relative to the rear frame 200.

[0132] It will be appreciated that the driving end 5412 of the driving member 541 provides driving force, and the bending rod 543 can transmit the driving force of the driving member 541 to the front frame 300 via the twelfth connecting rod 542, thereby driving the front frame 300 to rotate relative to the rear frame 200 (fixedly connected to the fixed end 5411). In this embodiment, the lengths of the twelfth connecting rod 542 and the bending rod 543, as well as the bending angle of the bending rod 543, can be set according to actual conditions, as long as they can drive the front frame 300 to fully fold or unfold relative to the rear frame 200.

[0133] In the above-described embodiment of the present invention, the folding capability of the vehicle is further enhanced through the use of multiple folding or telescoping structures. Furthermore, the various mechanisms of the vehicle can be modularly designed, allowing users to replace different module configurations as needed, thereby increasing the maintainability and upgradeability of the scooter. Furthermore, the present invention features a compact design, and the scooter occupies a smaller space when folded, making it convenient for storage in confined areas such as public transportation or household storage spaces. Furthermore, the design of the folding device 500 makes the scooter's folding and unfolding process faster, allowing users to complete the folding or unfolding operation in a short period of time.

[0134] The above are merely embodiments of the mobility scooter of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
