[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1-4 The image shown is an embodiment provided by this utility model.

[0031] The utility model discloses a kind of sliding plates, comprising: plate body 10, two groups of rolling components 20 and brake device 30, two groups of rolling components 20 are arranged in the bottom of plate body 10 in front and back, the connecting mode and the setting position of two groups of rolling components 20 and plate body 10 are similar with common sliding plate, so that sliding plate can be stable sliding, brake device 30 is arranged on plate body 10, generally, brake device 30 is arranged in the front and back two ends close to plate body 10, as a preferred scheme, brake device 30 is arranged in the rear end of plate body 10, can make the brake operation of sliding plate more safe in downhill process. Figure 4As shown, when the bottom of the brake piece 33 is in contact with the wheel surface of the roller 22, the brake piece 33 generates a frictional resistance to the rolling of the roller 22 to reduce the rotating speed of the roller 22, thereby achieving braking. The greater the force with which the pedal 31 is stepped, the greater the frictional force generated by the brake piece 33 on the roller 22. The user can control the stepping force according to the need for deceleration, thereby achieving slow braking or emergency braking. Compared with the conventional braking technique for controlling the braking of the skateboard, the brake device 30 provided in the embodiment of the utility model does not need to master difficult braking techniques or to swing the body or change the center of gravity by a large amplitude. It only needs to slightly move the forefoot to more simply achieve braking. It is more friendly to beginners of the skateboard and has lower braking difficulty and higher safety.

[0032] Further, the included angle between the pedal 31 and the plate body 10 is less than or equal to 30°. When the user steps on the pedal 31, the user does not need to raise the leg, but only needs to slightly lift the forefoot to hold the pedal 31, and the operation is more relaxed.

[0033] Specifically, the connecting rod 32 is sleeved with a reset spring 35. The upper end of the reset spring 35 is in abutment with the bottom of the pedal 31, and the lower end of the reset spring 35 is in abutment with the top of the plate body 10. The pedal 31 can be automatically reset after being depressed, which is convenient for use. In addition, in an optional embodiment, the reset spring 35 or the elastic member can also be directly arranged between the pedal 31 and the plate body 10. It is only necessary to fix the two ends of the reset spring 35 or the elastic member.

[0034] Further, the bottom width of the brake piece 33 is greater than or equal to the wheel surface width of the roller 22, so that the brake piece 33 can form a greater contact area with the wheel surface of the roller 22 during braking, thereby increasing the frictional resistance to the roller 22 and improving the braking effect. Alternatively, the position where the bottom of the brake piece 33 is in contact with the roller 22 is detachably provided with a friction plate (not shown in the drawings). The friction plate can be made of a material with a large friction coefficient, and the detachable arrangement facilitates the replacement of the friction plate. In addition, the shape of the bottom of the brake piece 33 can be a plane or a curved surface that is adapted to the roller 22.

[0035] Specifically, two connecting rods 32, two brake pieces 33 and two support pieces 34 are arranged, respectively. The two connecting rods 32, the two brake pieces 33 and the two support pieces 34 are symmetrically distributed on both sides of the bottom of the plate body 10 and correspond to the positions of the two rollers 22, respectively. The brake device 30 can balance the rotating speeds of the two rollers 22 during braking, thereby preventing the imbalance of the skateboard.

[0036] Specifically, the support 34 is arranged on the outer side of the roller 22 and is inclined backward, a inner and outer thread adapter nut can be arranged on the end of the wheel shaft 23 to replace the original conventional nut for fixing the roller 22, and a conventional nut is used to fix the support 34 on the wheel shaft 23, the upper ends of the two supports 34 are horizontally connected with a support shaft 36, the horizontal plane where the support shaft 36 is located is higher than the top of the roller 22 or is flush with the top of the roller 22, the rear end of the brake 33 is rotationally connected with the support shaft 36, so that the bottom of the rear end of the brake 33 is flush with or lower than the top of the roller 22, so that the front end of the brake 33 only needs to swing slightly to contact or separate from the roller 22, which is beneficial to shorten the brake stroke.

[0037] Further, the front ends of the two brakes 33 are horizontally connected with a cross beam 37, and the lower end of the connecting rod 32 is connected with the cross beam 37, the cross beam 37 is arranged to unify the swing range of the two brakes 33, so that the braking force of the two brakes 33 on the two rollers 22 is consistent, and the balance and stability of the skateboard during braking are improved.

[0038] Further, the top of the cross beam 37 is provided with a U-shaped elastic piece 38, and the free end of the U-shaped elastic piece 38 is connected with the lower end of the connecting rod 32, the U-shaped elastic piece 38 is arranged to buffer the depression of the brake 33 during braking, so as to avoid the user from stepping on the brake too hard and to improve the use safety of the brake device 30.

[0039] Obviously, the above-described embodiments are only some embodiments of the present application, not all embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some technical features therein. Any equivalent structure made by using the contents of the present application specification and drawings, directly or indirectly applied to other related technical fields, is also within the patent protection scope of the present application.
