Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses a pedal capable of being automatically adjusted, which is shown in a schematic view in fig. 1a and comprises a pedal bottom plate 10, a first baffle plate 20 and a second baffle plate 30, wherein the first baffle plate 20 and the second baffle plate 30 are oppositely arranged on the pedal bottom plate along a preset direction and are used for fixing feet; at least one of the first baffle 20 and the second baffle 30 is a slidable baffle 40; the adjusting part is shown in fig. 1b, and the pedal further comprises: a driving mechanism 50 for driving the slidable blocking plate 40 to move in the predetermined direction, a foot position measuring device 70 and a central processing unit 60; the cpu 60 is electrically connected to the foot position measuring device 70 and the driving mechanism 50, respectively.
In this embodiment, the preset direction may be that the left and right sides of the pedal base plate are oppositely provided with the baffle, or the front and back directions are oppositely provided, or even the diagonal angles are oppositely provided. Of course, the number of the baffles is not limited in this embodiment, that is, one pair of the baffles arranged oppositely may be used, or two or more pairs of the baffles arranged oppositely may be used, but at least one of the pair of the baffles arranged oppositely may be a slidable baffle that can move in a direction away from or close to the opposite baffle. Therefore, the feet of different users can be correspondingly fixed. For example, two baffles are oppositely arranged on the left side and the right side of the pedal base plate, as shown in fig. 2, a left baffle 21 and a right baffle 31 are respectively arranged on the left side and the right side of the pedal base plate 10, and the method specifically comprises the following steps:
(1) The left baffle 21 is a fixed baffle, and the right baffle 31 is a slidable baffle. The right shutter 31 is movable in the left-right direction, that is, the right shutter 31 is movable in a direction to approach or separate from the left shutter. Here we can generally set up the sliding tray on pedal bottom plate, and right baffle accessible sliding tray removes about like this, and so alright slide to different positions according to the width of different user's feet to fixed user's foot avoids user's foot to slide and causes the accident. In this scheme, when the user placed the foot on the running-board, the position that general foot was placed need be close to left baffle (fixed stop), and foot position measuring device detects out the positional information of foot again, then central processing unit controls actuating mechanism drive right baffle (slidable baffle) and slides to the relevant position left (left baffle direction promptly) according to this positional information to play the effect of fixed user foot.
(2) The left baffle 21 is a slidable baffle, and the right baffle 31 is a fixed baffle. In contrast to the above manner, the right baffle 31 is a fixed baffle and is not slidable, and the left baffle 21 is slidable left and right, so as to slide to corresponding positions according to the widths of the feet of different users, and fix the feet of the users. In this scheme, when the user placed the foot on the running-board, the position that the foot was placed need be close to right baffle (fixed stop), then foot position measuring device monitoring user foot's positional information, then central processing unit is according to the positional information of user foot that foot position measuring device monitored, and control actuating mechanism drive left baffle (slidable baffle) slides to corresponding position right (being right baffle direction) to play the effect of fixed user foot.
(3) Both the left shutter 21 and the right shutter 31 are slidable shutters. In this scheme, all can the horizontal slip of controlling two baffles, for example control two baffle initial position and be pedal bottom plate's the left and right sides both ends relative setting, but these two baffles relative motion fix user's foot jointly.
Of course, if the user's foot is to be fixed, a pair of baffles may be disposed on the front and rear ends and the left and right ends of the pedal base plate, respectively. Thereby securing the user's foot from all directions.
The foot position measuring device in the embodiment is used for detecting the position information of the feet of the user on the pedal base plate, so that the central processor controls the driving mechanism to drive the slidable baffle plate to slide to the corresponding position according to the position information, and the feet of the user are fixed. Of course, when the user wants to get off the rehabilitation machine, for example, the central processing unit receives the end command, and then controls the driving mechanism to drive the slidable baffle plate to move to the initial position, and the foot of the user is no longer fixed.
In the above embodiments, the foot position measuring device may be implemented in various ways, specifically including:
(1) The foot position measuring device includes: and the pressure sensing matrix is built in the whole pedal bottom plate and consists of N pressure sensors. As shown in fig. 3, the pressure sensors 71 are disposed on the pedal base plate 10 to form a pressure sensor matrix or a pressure sensor cloud, so that once a user steps on the pedal base plate 10, the pressure sensors 71 on the pedal base plate can sense the pressure values, and the pressure sensors output respective detected pressure values, and the central processor can obtain the foot position information of the user according to the pressure values output by the pressure sensors and the respective position information of the pressure sensors, so as to control the driving mechanism to drive the slidable baffle plate to slide to a corresponding position, thereby fixing the foot of the user. Preferably, the denser the arrangement of pressure sensors on the footrest floor, the higher the accuracy with which the foot position information of the user is obtained.
(2) The foot position measuring device includes: and the distance measuring sensor is arranged at one end of the slidable baffle plate, which is close to the pedal bottom plate. As shown in FIG. 4, a pair of slidable plates 40 is installed on the footrest base plate 10 to be slidable back and forth for fixing the feet of the user. The distance sensor 72 can detect the distance to the front obstacle, for example, when the user places his foot on the pedal base plate 10, the distance sensor 72 can detect the distance between the baffle and the front user's foot, and the cpu can control the driving mechanism to drive the slidable baffle to slide according to the distance information. Preferably, the distance measuring sensor includes: any one of an infrared ranging sensor, a laser ranging sensor, or an ultrasonic ranging sensor.
(3) The foot position measuring device includes: and a current detector for detecting the magnitude of the drive current of the drive mechanism. In this scheme, current detection meter is connected with actuating mechanism and central processing unit electricity respectively, when user's foot was placed on pedal bottom plate, actuating mechanism slowly promoted the slidable baffle and slides to user foot direction, when sliding to user foot position place, actuating mechanism promoted the thrust of slidable baffle will increase (because foot stops, the resistance has increased), if thrust needs to increase, must actuating mechanism's drive current also increase, consequently, as long as it increases to detect actuating mechanism's drive current change, and when the change volume reached predetermined current change volume, alright judge that the current position of this slidable baffle is just the position of user foot, consequently, central processing unit alright judge whether can stop driving according to the drive mechanism's that current detection meter detected electric current size, thereby make this slidable baffle stop sliding.
