Detailed Implementation

[0026] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0027] like Figures 1-6 As shown, the roller skates provided in this embodiment include a shoe 1 and a roller skating assembly 2 connected to the bottom of the shoe 1. The roller skating assembly 2 includes a front wheel 3 and two rear wheels 4, and a drive mechanism connected between the front wheel 3 and the two rear wheels 4. A connecting rod 5 is connected between the two rear wheels 4. Two rear wheel frames 6 are rotatably mounted on the outer wall of the connecting rod 5. A front wheel frame 7 rotatably connected to the front wheel 3 is provided between the two rear wheel frames 6. The rear wheel frames 6 and the front wheel frames 7 are rotatably connected by a rotating shaft 11. The shoe 1 is fixedly connected to the top of the front wheel frame 7. The drive mechanism includes a driving gear 8, an intermediate gear set 9, and a driven gear 10 that cooperate with each other. The intermediate gear set 9 is located between the driving gear 8 and the intermediate gear set 9. The driving gear 8 is connected to the end of the front wheel frame 7 away from the front wheel 3. The driven gear 10 is mounted on the middle outer wall of the connecting rod 5 and is located between the two rear wheel frames 6. The intermediate gear set 9 is movably mounted between the two rear wheel frames 6. With the roller assembly 2 in place, pressing down on the front wheel frame 7 causes the front wheel frame 7 and the rear wheel frame 6 to rotate relative to each other around the pivot 11. At this time, the driving gear 8 drives the intermediate gear set 9 and the driven gear 10, thereby driving the rear wheel 4 to rotate, which in turn drives the front wheel 3 to move synchronously, thus achieving the function of assisting forward movement. Therefore, users only need to alternately lift and press their left and right feet to move quickly, thereby increasing the speed of movement and saving energy. With the intermediate gear set 9 in place, different intermediate gear sets 9 can be configured to control the magnitude of single acceleration, so as to adapt to the use of people of different ages.

[0028] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the intermediate gear set 9 includes: a first gear 12, which is rotatably mounted between the two rear wheel frames 6 and meshes with the driven gear 10; a second gear 13, located between the first gear 12 and the driving gear 8, which is rotatably connected to the two rear wheel frames 6 and can move up and down; both the first gear 12 and the second gear 13 are double gears; the driving gear 8 is a sector gear; both ends of the rotating shaft 11 are equipped with mounting caps 14; the top of the rear wheel frame 6 is connected to a mounting block 15, and the mounting block 15 has a movable groove 16 that mates with the central shaft of the second gear 13. With the arrangement of the first gear 12, the second gear 13, and the movable groove 16, the second gear 13 can mesh with the first gear 12 and the drive gear 8 when it is at the lowest point of the movable groove 16. Therefore, when the foot is pressed down, the front wheel frame 7 is pressed down, and the drive gear 8 rotates relative to the rear wheel frame 6, pressing the second gear 13 into the lowest point of the movable groove 16. At this time, the drive gear 8 meshes with the second gear 13, thereby driving the first gear 12 to rotate, which in turn drives the rear wheel 4 to rotate forward. When the foot is lifted, the rear wheel frame 6 and the rear wheel 4 rotate relative to the front wheel frame 7. At this time, the drive gear 8 rotates in the opposite direction, which applies an upward force to the second gear 13, causing the second gear 13 to disengage from the first gear 12, thus preventing the rear wheel 4 from rotating in reverse. This process is repeated to achieve accelerated movement. By setting both the first gear 12 and the second gear 13 as double gears, the output speed of the intermediate gear set 9 can be increased. By setting the drive gear 8 as a sector gear, the weight can be reduced.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the front wheel carrier 7 is positioned above the two rear wheel carriers 6, and the width of the front wheel carrier 7 is greater than the distance between the two rear wheel carriers 6. A connecting block 17 is fixedly connected to the bottom of the front wheel carrier 7, and a first rotating hole 18 that mates with the rotating shaft 11 is provided on the connecting block 17. A second rotating hole 19 that mates with the rotating shaft 11 is provided at the end of the rear wheel carrier 6 away from the rear wheel 4. The diameter of the rear wheel 4 is greater than the diameter of the front wheel 3. By positioning the front wheel carrier 7 above the two rear wheel carriers 6 and ensuring that its width is greater than the distance between the two rear wheel carriers 6, the front wheel carrier 7 can prevent further rotation when the front wheel carrier 7 and the rear wheel carriers 6 are parallel, thus preventing injury to the user's feet. By ensuring that the diameter of the rear wheel 4 is greater than the diameter of the front wheel 3, power loss can be reduced, and operability and stability can be improved.

[0030] In this embodiment, as Figures 1-6 As shown in the figure, the working process of a roller skate provided in this embodiment is as follows:

[0031] Step 1: When the user presses down, the front wheel frame 7 will be pressed down, the drive gear 8 will rotate relative to the rear wheel frame 6, and the second gear 13 will be pressed into the lowest point of the movable groove 16. At this time, the drive gear 8 and the second gear 13 mesh, thereby driving the first gear 12 to rotate, which in turn drives the rear wheel 4 to rotate and move forward.

[0032] Step 2: When the foot is lifted, the rear wheel frame 6 and the rear wheel 4 rotate relative to the front wheel frame 7. At this time, the drive gear 8 rotates in the opposite direction, which will exert an upward force on the second gear 13, causing the second gear 13 to disengage from the meshing state with the first gear 12, so that the rear wheel 4 will not be driven to reverse.

[0033] Step 3: Users can alternately lift and press their left and right feet to move quickly.

[0034] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
