DETAILED DESCRIPTION

[0081] The utility model will be further explained in connection with the drawings and examples.

[0082] Example 1:

[0083] As Figures 1 to 10 shown, a roller skate, comprising:

[0084] bottom plate 1;

[0085] two groups of roller 23 mechanism, respectively and parallelly arranged on the bottom plate 1;

[0086] pedal 3, with the bottom plate 1 movably connected through the reset mechanism;

[0087] at least one group of driving mechanism, respectively connected with the pedal 3 and the roller 23 mechanism, changes the relative position with the bottom plate 1 through the pedal 3, drives the roller 23 mechanism to move;

[0088] at least two groups of reset mechanism, connected with the pedal 3 and the bottom plate 1, control the relative position of the pedal 3 and the bottom plate 1;

[0089] foot fixing assembly, arranged on the upper surface of the pedal 3, is fixed relative to the human foot.

[0090] The driving mechanism comprises:

[0091] The one-way rotating assembly is connected with the rotating shaft 22 of the roller 23 mechanism.

[0092] The rack 42 is fixedly connected with the lower surface of the pedal 3 and is engaged with the one-way rotating assembly. The relative position between the rack 42 and the one-way rotating assembly changes the rotation of the rotating shaft 22 of the roller 23 mechanism.

[0093] The one-way rotating assembly comprises:

[0094] The driven gear 411 is sleeved on the rotating shaft 22 of the roller 23 mechanism.

[0095] The fixed seat 412 is arranged on the bottom plate 1.

[0096] The connecting shaft 413 is rotatably arranged on the fixed seat 412.

[0097] The driving gear 414 is fixedly arranged on the connecting shaft 413 and is engaged with the rack 42.

[0098] The one-way gear 415 is fixedly arranged on the connecting shaft 413 and is engaged with the driven gear 411. The number of teeth of the one-way gear 415 is greater than that of the driven gear 411 and the driving gear 414. The one-way gear 415 is internally provided with a ratchet structure. When a torsion force in a certain direction is externally applied, the torsion force is transmitted. When a torsion force in the opposite direction is externally applied, the torsion force is not transmitted. This is similar to the structure of the freewheel disc of a bicycle. When the human body pedals the crank in the clockwise direction, the chain of the freewheel disc is rotated. When the human body pedals the crank in the counterclockwise direction, the freewheel disc remains stationary.

[0099] In this embodiment, the outer contour of the one-way gear 415 passes through the bottom plate 1. The bottom plate 1 is provided with a gap 11 for accommodating the rotation of the one-way gear 415. The driving mechanism further comprises:

[0100] The fixed part 43 is fixedly connected with the lower surface of the pedal 3 and is provided with a containing groove 431 on the side surface. The rack 42 is contained in the containing groove 431 and is fixedly connected with the fixed part 43. The bottom plate 1 is provided with a through hole 12 for the rack 42 to pass through at a position opposite to the rack 42.

[0101] The bottom box 7 is buckled on the lower surface of the bottom plate 1 and covers the part of the driving gear 414 exposed outside the bottom plate 1. The bottom box 7 is provided with an opening 71 opposite to the through hole 12 for the rack 42 to pass through. The opening 71 is located at the tail of the bottom box 7 in the advancing direction of the pedal 3.

[0102] In this embodiment, there are four reset mechanisms, which are arranged in a rectangle on the base plate 1 and fixed at both ends to the base plate 1 and the pedal 3 respectively; there are two sets of group drive mechanisms, which are respectively connected to two sets of roller 23 mechanisms.

[0103] The reset mechanism includes:

[0104] The first guide post 511 is vertically upwardly mounted on the base plate 1; the first guide post 511 is provided with a first guide hole 5111 along its axial direction; the base plate 1 is provided with a first bottom hole 13 directly opposite the first guide hole 5111;

[0105] The first sliding column 512 passes through the first guide column 511 at its lower part, with its lower end located below the base plate 1 and its upper end fixedly connected to the lower surface of the pedal 3.

[0106] The first sealing plate 513 is fixedly connected to the lower end of the first sliding column 512 and is located below the base plate 1. The diameter of the first sealing plate 513 is larger than that of the first bottom hole 13.

[0107] The first return spring 514 is sleeved on the outer surface of the first guide post 511, with its upper end abutting against the lower surface of the pedal 3 and its lower end abutting against the base plate 1.

[0108] In this embodiment, there are four reset mechanisms, which are arranged in a rectangle on the base plate 1 and fixed at both ends to the base plate 1 and the pedal 3 respectively; there are two sets of group drive mechanisms, which are respectively connected to two sets of roller 23 mechanisms.

[0109] In this embodiment, the roller 23 mechanism includes:

[0110] Two ear plates 21 are vertically arranged on the base plate 1, and the ear plates 21 are provided with through holes;

[0111] The rotating shaft 22 passes through the holes of the two ear plates 21 at both ends; the rotating shaft 22 is connected to the drive mechanism, and the drive mechanism drives the rotating shaft 22 to rotate.

[0112] Two rollers 23 are fixed to both ends of the rotating shaft 22 and are located on both sides of the base plate 1.

[0113] Furthermore, the foot fixing component includes:

[0114] The front buckle 61 is located at the front end of the pedal 3;

[0115] The rear sleeve 62 is located at the end of the pedal 3;

[0116] It also includes a brake head 8, which is mounted on the base plate 1.

[0117] In this embodiment, the roller skates are used as follows: the user's foot passes through the rear strap 62 and inserts into the front buckle 61, fixing the foot relative to the foot fixing component, and the ball of the foot rests on the pedal 3.

[0118] When the user lifts one foot, the pedal 3 rises relative to the base plate 1 under the action of the first return spring 514. At this time, the rack 42 drives the main drive gear to rotate. Since the one-way gear 415 rotates in one direction, it does not rotate in the opposite direction, so it does not drive the driven gear 411 to rotate until the first sealing plate 513 abuts against the base plate 1.

[0119] When the user steps down, the first return spring 514 is compressed, and at the same time the rack 42 drives the drive gear 414 to rotate. The drive gear 414 drives the one-way gear 415, and the one-way gear 415 drives the driven gear 411 to rotate, causing the roller 23 to rotate. This enables the roller skate to move on its own.

[0120] Example 2:

[0121] like Figures 11 to 14 As shown, the only difference between this embodiment and Embodiment 1 is the reset mechanism. In this embodiment, the reset mechanism includes:

[0122] The second guide post 521 is vertically upwardly mounted on the base plate 1; the lower end of the second guide post 521 is provided with a groove 5211; the second guide post 521 is provided with a second guide hole 5212 along its axial direction, the second guide hole 5212 is coaxially connected with the groove 5211, and the diameter of the second guide hole 5212 is smaller than the inner diameter of the groove 5211; the base plate 1 is provided with a second bottom hole 14 directly opposite the groove 5211;

[0123] The lower end of the second sliding post 522 is fitted inside the second guide post 521, and the upper end is fixedly connected to the lower surface of the pedal 3.

[0124] The first sliding plate 523 is disposed at the lower end of the second sliding post 522 and located in the groove 5211. The side of the first sliding plate 523 is in contact with the inner wall of the groove 5211.

[0125] The second return spring 524 is sleeved on the outer surface of the second guide post 521, with its upper end abutting against the lower surface of the pedal 3 and its lower end abutting against the base plate 1.

[0126] In this embodiment, a first sliding plate 523 is provided inside the second guide post 521 to make the lower surface of the base plate 1 as flat as possible, and it is used in the same way as the roller skates in Embodiment 1.

[0127] Example 3:

[0128] like Figures 15 to 20The difference between the embodiment and embodiment 1 is that the connection mode of the pedal 3 and the bottom plate 1 is different. Specifically, in the embodiment, the reset mechanism is two and is arranged in parallel at the tail end of the bottom plate 1, and the two ends are respectively hinged with the bottom plate 1 and the pedal 3; the driving mechanism is a group connected with the roller 23 mechanism at the tail end of the bottom plate 1; the pedal 3 is naturally upturned at the tail end;

[0129] Two connection assemblies are further included to connect the front end of the pedal 3 with the front end of the bottom plate 1; the connection assembly includes:

[0130] A vertical piece 91 is fixed at the upper surface of the bottom plate 1 at the lower end;

[0131] A connecting piece 92 is hinged at the upper end of the vertical piece 91 at the lower end and is fixed at the lower surface of the pedal 3 at the upper end;

[0132] The rack 42 is arc-shaped, and the rack 42 is always engaged with the driving gear 414 when the pedal 3 rotates around the hinge between the vertical piece 91 and the connecting piece 92.

[0133] The reset mechanism includes:

[0134] A third guide column 531 is hinged at the bottom plate 1 at the lower part; the third guide column 531 is internally provided with a cylindrical cavity 5311 along the axis; the third guide column 531 is provided with a third guide hole 5312 along the axis direction at the upper end, the third guide hole 5312 is coaxially communicated with the cavity 5311, and the diameter of the third guide hole 5312 is smaller than the inner diameter of the cavity 5311;

[0135] A third sliding column 532 is internally sleeved in the cavity 5311 at the lower end and is hinged with the lower surface of the pedal 3 at the upper end;

[0136] A second sliding plate 533 is arranged in the cavity 5311, and the side surface of the second sliding plate 533 is in contact with the inner wall of the cavity 5311;

[0137] A stop ring 534 is externally sleeved on the upper part of the third sliding column 532;

[0138] A third reset spring 535 is externally sleeved on the outer surface of the third sliding column 532, is in abutment with the stop ring 534 at the upper end, and is in abutment with the upper end of the third guide column 531 at the lower end.

[0139] Two reset mechanisms are arranged, and the pedal 3 is arranged to be inclined through the connection assembly, and the reset mechanism is improved according to the inclination of the pedal 3, so that only the heel and the pressure heel are needed when the human body slides. Specifically, the user uses as follows:

[0140] The roller skate of the embodiment is used as follows. The user puts the foot through the rear sleeve belt 62, inserts the foot into the front buckle belt 61, fixes the foot part relative to the foot fixing assembly, and places the foot palm on the pedal 3.

[0141] When the user lifts the heel of one foot, the pedal 3 rises relative to the base plate 1 under the action of the third reset spring 535, the entire reset mechanism rotates, and the rack 42 drives the main drive gear to rotate. The one-way gear 415 does not rotate in reverse due to one-way rotation, so it does not drive the driven gear 411 to rotate until the second slide plate 533 abuts the top of the cavity 5311 of the third guide column 531.

[0142] When the user steps down on the heel of this foot, the third reset spring 535 is compressed, and the rack 42 drives the driving gear 414 to rotate, which drives the one-way gear 415 and the driven gear 411 to rotate, causing the roller 23 to rotate, thus achieving self-movement of the rollerblade. The human body can slide more easily without having to completely lift the foot.

[0143] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
