The stepping cover 20 is movably connected to the base 10, as shown in fig. 1a to 1d, one side of the stepping cover 20 is rotatably connected to the base 10, for example, one side of the stepping cover 20 is hinged to the base 10 through a first rotating shaft 21, and the other side of the stepping cover 20 can approach or separate from the base 10 according to the stepping force of the user during the stepping process of the user on the stepping cover 20. Alternatively, as shown in fig. 2a to 2d, the step cover 20 may be floatingly disposed above the base 10. The tread cover 20 is movably connected with the base 10, so that the tread cover 20 can move relative to the base 10, and the tread cover 20 is close to or far away from the base 10.

When a user steps on the pedal cover 20, the position of the pedal cover 20 relative to the base 10 changes, or at least a portion of the pedal cover 20 changes relative to the base 10, specifically, when the pedal cover 20 is rotatably connected to the base 10, the position of the side of the pedal cover 20 away from the rotation connection end and the base 10 changes, and when the pedal cover 20 is floatingly disposed on the base 10, the position of the pedal cover 20 and the base 10 changes as a whole.

The position detecting assembly 30 is disposed between the base 10 and the stepping cover 20, and is configured to detect relative position information of the stepping cover 20 with respect to the base 10; the control element is electrically connected to the position detecting assembly 30 and is configured to execute a corresponding speed control command according to the relative position information detected by the position detecting assembly 30. The position detection assembly 30 is arranged to detect the relative position information between the treading cover plate 20 and the base 10, so as to control the speed of the whole vehicle.

In the present embodiment, the detection of the relative position information between the step cover 20 and the base 10 may be performed by directly detecting the height change information between the step cover 20 and the base 10 to reflect the relative position information, or may be performed by directly detecting the angle change between the step cover 20 and the base 10 to indirectly reflect the relative position information, and therefore, the position detection assembly 30 may directly detect the distance change between the calibration position on the step cover 20 and the calibration position on the base 10 in the vertical direction, or may detect the angle change between the step cover 20 and the base 10, which is not limited in the embodiment of the present invention.

As shown in fig. 1b to 1c, or as shown in fig. 2b to 2c, the step cover 20 may be connected with a guide member 21, and the guide member 21 is inserted into the base 10. Specifically, the base 10 may have a guide hole S therein, and an axis of the guide hole S may be perpendicular to the pedal assembly 100 in the mounted state of the vehicle speed control device. The cross-sectional dimension of the guide member 21 may be slightly smaller than the cross-sectional dimension of the guide hole S so that the guide member 21 can slide within the guide hole S.

The number of the guide elements 21 may be one or more than two, and may be selected according to the size of the treading cover 20 and the base 10, and when the size of the treading cover 20 and the base 10 is larger, the number of the guide elements 21 may be more. Those skilled in the art can design and select the material according to actual needs, and the material is not limited herein.

Based on the above, the position detecting assembly 30 may include the hall element 11 disposed on the base 10, and the magnetic steel 22 disposed on the guiding element 21 or the stepping cover plate 20; alternatively, the position detecting assembly 30 includes a hall element 11 provided on the guide element 21 or the step cover 20, and a magnetic steel provided on the base 10. The stepping on the cover plate 20 to change the position relative to the base 10 can cause the magnetic field cover plate generated by the magnetic steel 22, the hall element senses the change, and then the hall element transmits the changed magnetic field information to the control element, and the control element can be connected with a driving device (such as a hub motor) corresponding to the wheel to control the change of the rotating speed of the wheel. The Hall element detects position change, and it measures accurately, and the response is sensitive, and the volume is less, not occupation space.

In some exemplary embodiments, the hall element 11 and the magnetic steel 22 may be arranged as follows: as shown in fig. 1c, the side wall of the base 10 may have a mounting hole for mounting the hall element 11, and the hall element 11 may be detachably or non-detachably disposed in the mounting hole through the hall bracket 111. The magnet 22 may be detachably or non-detachably disposed on the side wall of the guide element 21, or the magnet 22 may be directly disposed on the side of the step cover 20 facing the base 10. It should be noted that, because the motion of the guiding element 21 is along the vertical linear motion, it is preferable to locate the magnetic steel 22 on the guiding element 21, so that when stepping on the cover plate 20, the change of the relative position between the magnetic steel 22 and the hall element 11 is only the distance change in height, so that the change of the magnetic field and the stepping depth are in an absolute change relationship, and the control of the stepping depth and the vehicle speed is more accurate.

In addition, referring to fig. 1a and 1b, when one side of the step cover 20 is rotatably connected to the base 10, the vehicle speed control apparatus may further include an intermediate link 40, one end of the intermediate link 40 is rotatably connected to one end of the guide member 21 away from the base 10, and the other end of the intermediate link 40 is rotatably connected to the step cover 20. The arrangement of the intermediate link 40 can convert the inclined treading force applied by the user to the treading cover plate 20 into the acting force of the intermediate link 40 in the vertical direction, and directly convert the acting force into the depth change.

Of course, in some other embodiments, the step cover 20 may not be connected to the guide element 21, and only the step cover 20 abuts against the guide element 21, and a preset damping may be provided between the step cover 20 and the base 10, for example, a torsion spring is provided at a rotational connection between the step cover 20 and the base 10, or the step cover 20 and the base 10 are connected through a compression spring, and a person skilled in the art may make a suitable choice on the elastic characteristic of the compression spring, so that the step cover 20 can also abut against the guide element 21 when the user does not step on the step cover 20. The user can push the guiding element 21 to extend into the guiding hole by stepping on the stepping cover 20, so that the position detecting assembly 30 can also detect the position change of the stepping cover 20 and the base 10.

As shown in fig. 1b and 2b, an elastic member 50 may be disposed between the tread cover 20 and the base 10, and the elastic member 50 may be used to provide elastic damping for the movement of the tread cover 20 toward the base 10. Specifically, the elastic member 50 may be a compression spring or even a rubber member. The elastic member 50 may also be a torsion spring when the tread cover 20 is rotatably coupled to the base frame 10. By providing the elastic member 50 between the step cover 20 and the base 10, the step cover 20 can be restored to the original state by the elastic restoring force of the elastic member 50 after the user releases the step cover 20. Moreover, the user can conveniently release the treading cover plate 20, for example, the treading force is switched from a larger treading force to a smaller treading force, when the applied treading force is larger, the corresponding vehicle speed can be larger, and when the user gradually releases the treading cover plate 20, the whole vehicle can gradually decelerate. Thereby realizing the acceleration and deceleration control of the vehicle speed.

In addition, the elastic element 50 can effectively improve the treading sensing effect, and is convenient for a user to control the vehicle speed. Moreover, a person skilled in the art can select the elastic member 50 with a suitable rigidity, when the rigidity of the elastic member 50 is too high, the user needs to apply a large pedaling force to pedal the cover plate 20, and when the rigidity of the elastic member 50 is too low, the user is not able to control the pedal cover plate 20 stably, and the situation that the user mistakenly steps on the cover plate 20 due to mistaken collision is easily caused. Therefore, the elastic member 50 with suitable rigidity can be selected by those skilled in the art according to the above requirements, and the embodiment of the present invention is not limited herein.

As shown in fig. 2c, the guiding element 21 may have a through hole extending along its axis, and the elastic member 50 may be disposed in the through hole, wherein the length of the elastic member 50 in the natural state is greater than that of the guiding element 21; or, the elastic element 50 is sleeved outside the guide element 21, and the length of the elastic element 50 in the natural state is greater than that of the guide element 21. The length of the elastic member 50 in a natural state is larger than that of the guide member 21, and the elastic member 50 can provide a damping effect to the step cover 20 when the step cover 20 is stepped on. The length of the elastic member 50 extending out of the guide element 21 can be designed by those skilled in the art according to the maximum treading depth required, so that the elastic member 50 can always provide damping function during the treading of the cover plate 20 by the user.

When the user is riding this electric scooter, a foot of user can stand on scooter's footboard subassembly 100, another foot can step on speed control device 1000 trample apron 20, begin to step on downwards and trample apron 20, and then can drive magnet steel downstream, lead to magnetic field to change, and hall element 11 can gather magnetic field information and pass to control element, begin to accelerate, and when upwards lifting the foot, the magnet steel kick-backs, and magnetic field reverse change begins to slow down.

As shown in fig. 2a and 2b, the step cover 20 can be floatingly disposed above the base 10, and when the elastic member 50 is sleeved outside the guiding element 21, the vehicle speed control device can include: the limiting plate 60, the limiting plate 60 can be used to be fixed on the base 10, the limiting plate 60 can be used to abut against the elastic member 50, and the limiting plate 60 can have a through hole 61 for the guiding element 21 to pass through. Specifically, the limiting plate 60 may be detachably connected to the base 10, for example, the limiting plate 60 may be detachably connected to the base 10 by a fastener such as a screw, or the limiting plate 60 may be detachably connected to the base 10 by a snap. Through the arrangement of the limiting plate 60, the elastic element 50 can be effectively prevented from being disengaged from the base 10, and the reliability of the vehicle speed control device is ensured.

Of course, in the manner that the step cover 20 is floatingly disposed on the base 10, the elastic member 50 may be disposed inside the guiding element 21, and the base 10 may also have a limiting portion (not shown) for preventing the guiding element 21 from completely falling off from the base, as long as the similar function can be achieved, and the embodiment of the present invention is not particularly limited.

Furthermore, as shown in fig. 2b, the guide element 21 may be fixed to the tread cover 20 in a detachable or non-detachable manner in such a manner that the tread cover 20 is floatably provided on the base 10. The number of the guiding elements 21 may be plural, and the shape of each guiding element 21 may be the same or different, for example, as shown in fig. 2b, two guiding elements 21 may be smooth cylindrical, and the other guiding element 21 may have a fixing portion 211 for fixing the magnetic steel 22 thereon, and the guiding element 21 having the fixing portion 211 for fixing the magnetic steel 22 may be detachably connected with the step cover 20 through the connecting plate 212.

It should be noted that, in the exemplary embodiment shown in fig. 2b, the number of the magnetic steels 22 is two, and the number of the corresponding fixing portions 211 is also two, and actually, the number of the magnetic steels 22 may also be one, and the embodiment of the present invention is not limited.
