The running platform assembly comprises a running board 110 suitable for mounting a running belt 111, a running frame 120 arranged around the running board 110 and a supporting base frame 130, wherein the supporting base frame 130 is positioned below the running board 110 and the running frame 120, the running board 110 is mounted on the running frame 120, pedal platforms 112 are further arranged on two sides of the running board 110, the pedal platforms 112 are fixedly connected with the running frame 120, and the running frame 120 is mounted on the supporting base frame 130. Here, the running board 110 is an elastic running board so as to have certain elasticity, and when a user runs on the treadmill 100, a downward impact force is applied to the running board 110, and the running board 110 is elastically deformed and rebounded, thereby playing a buffering effect.

In addition, the treadmill 100 further includes a front bracket 140 positioned in front of the treadmill assembly, wherein one upright 145 is respectively disposed at the left and right sides of the front bracket 140, and the front end of the support chassis 130 is respectively fixedly connected with the lower ends of the two uprights 145 of the front bracket 140, in other words, the support chassis 130 is fixedly mounted at the lower end of the upright 145 of the front bracket 140. Thus, the running board assembly is mounted to the lower portion of the front bracket 140 through the support chassis 130.

Further, the electromagnetic damping device 150 includes a first electromagnetic member 151 and a second electromagnetic member 152 installed to cooperate with the first electromagnetic member 151, and the first electromagnetic member 151 and the second electromagnetic member 152 generate the same magnetism to repel each other when they are energized, so as to levitate and support the running board 110. Specifically, the first electromagnetic element 151 and the second electromagnetic element 152 are respectively installed on two components of the running platform assembly (i.e. between the running frame 120 and the supporting chassis 130, or between the running board 110 and the running frame 120), in other words, the two components of the running platform assembly are connected by the electromagnetic damping device 150, so that, in the power-on state of the electromagnetic damping device 150, no matter the running frame 120 and the supporting chassis 130 are supported by the first electromagnetic element 151 and the second electromagnetic element 152 in a mutually floating manner (the running board 110 is fixed on the running frame 120), or the running board 110 and the running frame 120 are supported by the first electromagnetic element 151 and the second electromagnetic element 152 in a mutually floating manner (the running frame 120 is fixed on the supporting chassis 130), the running board 110 can be supported in a floating manner, specifically, the running board 110 is in a floating manner relative to the supporting chassis 130, and the supporting chassis 130 supports the running board 110 by the running frame 120. It can be understood that when the user runs on the treadmill 100, the elastic force generated by the elastic deformation of the running board 110 and the magnetic repulsive force between the first and second electromagnetic members 151 and 152 support the impact force of the user during running.

The controller 160 is coupled to the electromagnetic damping device 150, and the controller 160 is adapted to control the magnitude of the current output to the electromagnetic damping device 150 so as to adjust the magnetic repulsive force between the first electromagnetic member 151 and the second electromagnetic member 152. When the user runs on the treadmill 100, the elastic deformation amplitude of the running board 110 can be correspondingly adjusted by adjusting the magnitude of the magnetic repulsive force between the first electromagnetic member 151 and the second electromagnetic member 152, thereby realizing the control of the amplitude of the running board 110.

In addition, as shown in fig. 3, the treadmill 100 further includes a sensor 170, the sensor 170 being disposed at a suitable location on the deck assembly and coupled to the controller 160. Fig. 11 shows a schematic configuration of the sensor 170, and the sensor 170 is adapted to detect an instantaneous distance from the sensor 170 to the running board 110, thereby collecting an amplitude signal of the running board 110, and to transmit the collected amplitude signal to the controller 160 in real time, so that the controller 160 controls the magnitude of the current of the electromagnetic damping device 150 according to the received amplitude signal. According to one embodiment, the sensor 170 is an analog capacitive sensor that can detect the instantaneous distance from the sensor 170 to the running board 110 in order to collect the amplitude signal of the running board 110, but the invention is not limited thereto.

According to one embodiment, as shown in fig. 1 to 3, the running board 110 is fixedly connected with the running rack 120. A plurality of electromagnetic shock-absorbing devices 150 are installed between the running frame 120 and the supporting base frame 130. Wherein, the running frame 120 includes two left and right side tubes 125 disposed oppositely, the first electromagnetic element 151 and the second electromagnetic element 152 are selectively mounted on the side tube 125 and the supporting bottom frame 130 of the running frame 120, respectively, that is, one of the side tube 125 and the supporting bottom frame 130 of the running frame 120 is mounted with the first electromagnetic element 151, and the other is correspondingly mounted with the second electromagnetic element 152, so that the running plate 110 is supported on the supporting bottom frame 130 together with the running frame 120 in a floating manner. Here, one electromagnetic damping device 150 may be respectively disposed between the two side pipes 125 of the running frame 120 and the supporting bottom frame 130, or a plurality of electromagnetic damping devices 150 may be respectively disposed. In addition, a plurality of elastic rubber pads 105 are further disposed between the running rack 120 and the supporting chassis 130, for example, one elastic rubber pad 105 may be disposed at each of four corners of the running rack 120, but is not limited thereto. The running frame 120 is flexibly connected to the support chassis 130 by the elastic rubber pad 105. Thus, when the controller 160 controls the current magnitude of the electromagnetic damping device 150 to change, the magnetic repulsive force of the first and second electromagnetic elements 151 and 152 is increased or decreased accordingly, and the elastic deformation of the running plate 110 is changed, that is, when the magnetic repulsive force is increased, the elastic deformation of the running plate 110 is decreased, and when the magnetic repulsive force is decreased, the elastic deformation of the running plate 110 is increased, so as to control the amplitude of the running plate 110. It should be appreciated that in this embodiment, the running board 110 together with the running frame 120 vibrates with respect to the support chassis 130. Further, the sensor 170 is adapted to be mounted on the support chassis 130 so as to be able to detect the instant distance from the sensor 170 to the running board 110 or the running rack 120 (i.e. the distance of the running board 110 or the running rack 120 to the support chassis 130) in order to acquire an amplitude signal of the running board 110 (and the running rack 120).

According to one embodiment, as shown in fig. 4-6, the front of the running rack 120 is fixedly connected with the support chassis 130. A plurality of electromagnetic shock-absorbing devices 150 are installed between the running plate 110 and the running rack 120. Wherein, the running frame 120 includes two opposite left and right side tubes 125, the first electromagnetic element 151 and the second electromagnetic element 152 are selectively mounted on the bottom of the running board 110 and the side tubes 125 of the running frame 120, respectively, that is, one of the running board 110 and the side tubes 125 of the running frame 120 is mounted with the first electromagnetic element 151, and the other is correspondingly mounted with the second electromagnetic element 152, so that the running board 110 is supported on the running frame 120 in a floating manner. Here, one electromagnetic damping device 150 may be respectively disposed between both sides of the bottom of the running board 110 and both side pipes 125 of the running frame 120, or a plurality of electromagnetic damping devices 150 may be respectively disposed therebetween. In addition, a plurality of elastic rubber pads 105 are further disposed between the bottom of the running board 110 and the side tube 125 of the running rack 120, for example, one elastic rubber pad 105 may be disposed at each of four corners of the bottom of the running board 110, but is not limited thereto. The running board 110 is flexibly connected with the running rack 120 through the elastic rubber mat 105. Thus, when the controller 160 controls the current magnitude of the electromagnetic damping device 150 to change, the magnetic repulsive force of the first and second electromagnetic elements 151 and 152 is increased or decreased accordingly, and thus the degree of elastic deformation of the running plate 110 is changed, i.e. when the magnetic repulsive force is increased, the elastic deformation of the running plate 110 is decreased, and when the magnetic repulsive force is decreased, the elastic deformation of the running plate 110 is increased, and the control of the amplitude of the running plate 110 is also realized. It should be appreciated that in this embodiment, the running board 110 vibrates with respect to the running rack 120 and the support chassis 130.

Further, the sensor 170 is adapted to be mounted on the running board 120 so as to detect an instant distance from the sensor 170 to the running board 110 (i.e., a distance between the running board 110 and the running board 120) in order to collect an amplitude signal of the running board 110.

It should be noted that, the utility model discloses a controller 160 embeds the predetermined amplitude that accords with scientific amplitude standard, and controller 160 is suitable for and judges whether the actual amplitude of running board 110 is within the predetermined range of predetermined amplitude according to the amplitude signal after receiving the amplitude signal that sensor 170 sent to according to the current size of judgement result instantaneous control electromagnetism damping device 150. Specifically, if it is determined that the actual amplitude of the running plate 110 is lower than the predetermined range of the preset amplitude, the controller 160 controls the current of the electromagnetic damping device 150 to decrease according to the determination result, so that the magnetic repulsive force between the first electromagnetic member 151 and the second electromagnetic member 152 is decreased, thereby increasing the amplitude of the running plate 110 (i.e., increasing the elastic deformation amplitude); if it is determined that the actual amplitude of the running plate 110 is higher than the predetermined range of the preset amplitude, the controller 160 controls the current of the electromagnetic damping device 150 to increase according to the determination result, so that the magnetic repulsive force between the first electromagnetic member 151 and the second electromagnetic member 152 is increased, and thus the amplitude of the running plate 110 is decreased (i.e., the elastic deformation amplitude is decreased). Thus, the amplitude of the running board 110 can be ensured to be always within the predetermined range of the preset amplitude, thereby providing the best running experience for the user.
