[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 8 The figure shows the connection structure diagram of the existing front folding rod 13 and the rear folding rod 14. In the unfolded state, the rear folding rod 14 is below the front folding rod 13, and the front end of the rear folding rod 14 is hinged to the middle part of the front folding rod 13. During driving, under the pressure of the seat structure and the user's weight, the rear end of the front folding rod 13 is pressed against the front end of the folding rod. Since the front end of the rear folding rod 14 needs to reserve a rotation margin (the margin is reserved at position C in the figure), there is a gap between the front end of the rear folding rod 14 and the front folding rod 13. That is to say, in fact, the front folding rod 13 and the rear folding rod 14 are not completely parallel, resulting in the rear end of the front folding rod 13 (position D in the figure) being pressed against the middle position of the rear folding rod 14. The local pressure is very large, which can easily cause deformation of the front folding rod 13 and the rear folding rod 14, causing adverse effects on the service life of the mobility scooter.

[0027] like Figures 1 to 7As shown, a folding scooter with a long service life includes a folding frame 1, a front assembly 2, a seat assembly 3, a front wheel assembly 4 and a rear wheel assembly 5. The folding frame 1 includes a front cross beam 11, a mounting cross beam 12, a front folding rod 13, a rear folding rod 14, a first hinge plate 15, a second hinge plate 16, a limit block 17 and a locking assembly 18. The first hinge plate 15 is fixed to the front cross beam 11, and the front end of the front folding rod 13 is rotatably mounted on the first hinge plate 15. The first hinge plate 15 and the front folding rod 13 are each provided with two groups and correspond to the left and right sides of the front cross beam 11. The rear folding rod 14 is provided with two groups and is respectively fixed to the mounting cross beam. On the left and right sides of 12, the two groups of rear folding rods 14 correspond to the upper inner sides of the two groups of front folding rods 13 respectively, the upper end of the second hinge plate 16 is fixed to the front end of the rear folding rod 14, and the rear side of the front folding rod 13 is rotatably mounted on the lower end of the second hinge plate 16, the limit block 17 corresponds to the rear side of the second hinge plate 16 and the lower end is fixed to the front folding rod 13, the upper end of the limit block 17 is provided with a laterally protruding limit plate 171, the lower end surface of the limit plate 171 contacts the upper end surface of the rear folding rod 14, the front and rear ends of the locking assembly 18 are respectively mounted on the front cross beam 11 and the mounting cross beam 12, for fixing the front cross beam 11 and the mounting cross beam 12;

[0028] The front assembly 2 is fixed on the front cross beam 11, the front wheel assembly 4 is installed on the front cross beam 11 and connected to the power output end of the front assembly 2, the front assembly 2 is used to drive the front wheel assembly 4 to steer, the lower end of the seat assembly 3 is fixed on the front folding rod 13 and the rear folding rod 14, and the rear wheel assembly 5 is fixed to the rear end of the rear folding rod 14.

[0029] During the unfolding of the mobility scooter, the unfolding of the folding frame 1 drives the overall unfolding of the mobility scooter. After the unfolding is completed, the front folding rod 13 and the rear folding rod 14 are staggered up and down and left and right. The limit plate 171 on the limit block 17 is placed on the front end of the rear folding rod 14. The locking assembly 18 fixes the front crossbeam 11 and the mounting crossbeam 12. The entire vehicle is in a stable unfolded state. During driving, the weight of the seat assembly 3 and the operator is applied to the front folding rod 13 and the rear folding rod 14. The limit plate 171 plays a supporting role, so that the front folding rod 13 and the rear folding rod 14 remain in a relatively static state. The advantages of this design are: 1. The front folding rod 13 and the rear folding rod 14 are staggered up and down, and there is no direct contact between the two. The bottom surface of the limiting plate 171 contacts the front end of the rear folding rod 14, which increases the force-bearing area, thereby ensuring that the front folding rod 13 and the rear folding rod 14 are not easily deformed or damaged, thereby improving the service life of the scooter; 2. The limiting block 17 is the main force-bearing component. When the limiting block 17 is damaged, only the limiting block 17 needs to be replaced separately, and the replacement efficiency is high and the cost is low; 3. The front folding rod 13 and the rear folding rod 14 are staggered left and right, so that the front wheels and the rear wheels are also set to be staggered left and right, which is beneficial to reducing the width of the scooter after folding and reducing the space occupied.

[0030] The lower end surface of the limiting plate 171 is a downwardly protruding arc surface, and the contact surface between the rear folding rod 14 and the limiting plate 171 is a downwardly concave arc surface.

[0031] Setting the lower end surface of the limiting plate 171 into an arc-shaped surface to match the concave arc-shaped surface on the rear folding rod 14 can further increase the force-bearing area and disperse the pressure outward, thereby improving the service life of the limiting plate 171.

[0032] The locking assembly 18 includes a third hinge plate 181, a fourth hinge plate 182, a rocker 183, a folding lock column 184, an unfolding lock column 185, a locking plate 186, a connecting column 187, a spring 188 and a driving handle 189. The lower end of the third hinge plate 181 is fixed to the front crossbeam 11, the rear end of the fourth hinge plate 182 is fixed to the mounting crossbeam 12, and the front and rear sides of the fourth hinge plate 182 are respectively provided with a first hinge portion 1821 and a second hinge portion 1 822, the front and rear ends of the swing rod 183 are rotatably mounted on the upper end of the third hinge plate 181 and the first hinge portion 1821 respectively. The folding lock column 184 and the unfolding lock column 185 are both fixed to the rear end of the swing rod 183 and correspond to the front and rear sides of the first hinge portion 1821 respectively. The locking plate 186 includes an integrally arranged unfolding lock rod 1861, a folding lock rod 1862 and a handle connecting plate 1863. The rear end of the unfolding lock rod 1861 is rotatably mounted on the second hinge portion 1821. On the connecting portion 1822, a first buckle groove 18611 is provided below the front end of the unfolding lock rod 1861. The first buckle groove 18611 is used to buckle with the unfolding lock column 185 in the unfolded state. The connecting column 187 is fixed on the fourth hinge plate 182 and corresponds to the bottom of the second hinge portion 1822. The folding lock rod 1862 corresponds to between the unfolding lock column 185 and the connecting column 187 and the upper end is connected to the unfolding lock rod 1861. The rear side of the lower end of the folding lock rod 1862 is provided with a guide bevel. The folding lock rod 1862 is provided with a second buckle groove 18622 and a connecting hook 18623 corresponding to the upper side of the guide inclined surface 18621 in sequence. The second buckle groove 18622 is used to buckle the folding lock column 184 in the folded state. The two ends of the spring 188 are respectively fixed on the connecting column 187 and the connecting hook 18623. The handle connecting plate 1863 is connected to the upper end of the unfolding lock rod 1861, and the driving handle 189 is fixed on the handle connecting plate 1863.

[0033] When folding the scooter, first rotate the locking plate 186 clockwise by driving the handle 189, so that the first buckle groove 18611 is disengaged from the unfolding lock column 185, releasing the locked state, and then lift the driving handle 189 upward, and the swing rod 183 rotates counterclockwise around the first hinge portion 1821. The rear folding rod 14 rotates clockwise relative to the front folding rod 13 through the second hinge plate 16, so that the front folding rod 13 and the rear folding rod 14 are folded. When the folding lock column 184 touches the guide slope 18621, as the folding action continues, the folding lock column 184 moves the guide slope 18621 away from the folding rod. The connecting column 187 is squeezed in the direction of the spring 188, and the spring 188 is stretched until the folding lock column 184 enters the second buckle groove 18622. Under the action of the spring 188, the second buckle groove 18622 buckles the folding lock column 184, thereby achieving locking in the folded state. Similarly, when the scooter needs to be unfolded, the locking plate 186 is rotated clockwise by driving the handle 189 to disengage the second buckle groove 18622 from the folding lock column 184, releasing the locked state, and moving the driving handle 189 downward to gradually unfold the scooter, and finally the first buckle groove 18611 locks the unfolding lock column 185.

[0034] The driving handle 189 includes a first pull rod 1891 and a second pull rod 1892 . The first pull rod 1891 is horizontally arranged and its rear end is fixed to the handle connecting plate 1863 . The second pull rod 1892 is vertically arranged and its lower end is fixed to the handle connecting plate 1863 .

[0035] In the unfolded state, the second pull rod 1892 is in a vertical state. At this time, the locking plate 186 can be easily rotated clockwise through the second pull rod 1892. At the same time, the front end of the first pull rod 1891 is tilted upward, and then the first pull rod 1891 is directly lifted upward to make the locking plate 186 continue to rotate clockwise and complete the folding. In the folded state, the first pull rod 1891 is in a vertical state. At this time, the first pull rod 1891 is used to drive the locking plate 186 to rotate, which is more convenient for the unfolding operation. This design sets the driving handle 189 to a combination of the first pull rod 1891 and the second pull rod 1892, so that the unfolding and folding actions of the mobility scooter are easier to operate.

[0036] The front assembly 2 includes a mounting base 21, a drive shaft 22, a drive plate 23, a fixed support rod 24, a telescopic support rod 25 and a front controller 26. The mounting base 21 is fixed to the middle of the front cross beam 11, the drive shaft 22 is rotatably mounted on the mounting base 21 and the upper and lower ends protrude from the mounting base 21, the drive plate 23 is fixed to the lower end of the drive shaft 22 and is drive-connected to the front wheel assembly 4, the fixed support rod 24 is fixed to the upper end of the drive shaft 22, the telescopic support rod 25 is fixed to the fixed support rod 24 and its position is adjustable in the vertical direction, and the front controller 26 is fixed to the upper end of the telescopic support rod 25.

[0037] The front controller 26 controls the operation and stop of the rear wheel assembly 5, and drives the telescopic support rod 25 to rotate, thereby rotating the drive plate 23 through the fixed support rod 24 and the drive shaft 22, and then drives the front wheel assembly 4 to turn. After the scooter is folded, the telescopic support rod 25 can be retracted to a certain distance to reduce the occupied space.

[0038] The seat assembly 3 includes a fifth hinge plate 31, a first supporting foot 32, a second supporting foot 33, a mounting vertical rod 34, a seat cushion component 35 and a backrest component 36. The fifth hinge plate 31 is fixed to the rear end of the rear folding rod 14, the first supporting foot 32 and the second supporting foot 33 are cross-arranged and hinged to each other in the middle, the lower end of the first supporting foot 32 is hinged to the rear end of the front folding rod 13, the lower end of the second supporting foot 33 is hinged to the upper end of the fifth hinge plate 31, the lower end of the mounting vertical rod 34 is hinged to the upper end of the first supporting foot 32, the fifth hinge plate 31, the first supporting foot 32, the second supporting foot 33 and the mounting vertical rod 34 are each provided in two groups and correspond to the left and right sides of the folding frame 1, the front lower side of the seat cushion component 35 is hinged to the upper end of the second supporting foot 33, the rear end of the seat cushion component 35 is hinged to the middle part of the mounting vertical rod 34, and the left and right sides of the backrest component 36 are respectively fixed to the upper ends of the two groups of mounting vertical rods 34.

[0039] During the folding process, the first support leg 32 and the second support leg 33 both rotate clockwise, and the front end of the first support leg 32 and the front end of the second support leg 33 gradually approach each other and gradually tend to a vertical state. The folding action of the first support leg 32 and the second support leg 33 simultaneously drives the mounting vertical rod 34 to move downward, and drives the seat cushion component 35 to rotate clockwise and then also to a vertical state, so that the space occupied by the vehicle can be compressed as much as possible after folding, making it easy to store and carry.

[0040] The rear wheel assembly 5 includes a middle hinge rod 51, a bottom hinge rod 52, a top hinge rod 53, a sixth hinge plate 54, a rear wheel drive component 55, a rear wheel body 56 and an anti-roll wheel 57. The front ends of the middle hinge rod 51 and the bottom hinge rod 52 are hinged to the middle and lower ends of the fifth hinge plate 31 respectively, and the rear ends of the middle hinge rod 51 and the bottom hinge rod 52 are hinged to the upper end and the middle of the sixth hinge plate 54 respectively. The anti-roll wheel 57 is rotatably mounted on the lower end of the sixth hinge plate 54, the front end of the top hinge rod 53 is hinged to the lower end of the second support foot 33, and the rear end of the top hinge rod 53 is hinged to the middle of the middle hinge rod 51. The left and right sides of the rear wheel drive component 55 are respectively fixed on the two groups of middle hinge rods 51, and the rear wheel body 56 is provided in two groups and is respectively fixed on the power output ends on the left and right sides of the rear wheel drive component 55.

[0041] During the folding process, the second support leg 33 rotates clockwise, thereby driving the top hinge rod 53 to rotate. The fifth hinge plate 31, the sixth hinge plate 54, the middle hinge rod 51 and the bottom hinge rod 52 form a quadrilateral structure. Driven by the top hinge rod 53, the quadrilateral structure drives the rear wheel body 56 and the anti-roll wheel 57 to move toward the side of the front wheel assembly 4. After folding is completed, the front wheel and the rear wheel body 56 are staggered in the left and right directions, so that the scooter can be folded more fully and the occupied space is further compressed.

[0042] In this design, a battery assembly 6 is also included. The battery assembly 6 is fixed on the folding frame 1. Two groups of battery assemblies 6 are provided and correspond to the left and right sides of the locking assembly 18 respectively. The battery assembly 6 is electrically connected to the front assembly 2 and the rear wheel assembly 5.

[0043] The battery assembly 6 is divided into two groups corresponding to the left and right sides of the locking assembly 18 respectively, which can reduce the capacity of a single battery group and make the capacity of a single battery group meet the regulations of aircraft transportation, making it easier to carry and transport the batteries.

[0044] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
