[0077] In the preferred embodiment of the present application, as shown in Figure 5 The control assembly 5 comprises:

[0078] a control unit 51 connected with the pressure sensors 43, the distance sensors 45 and the driving motor 21, for generating a display instruction according to the pressure data and the ground clearance data, and generating a driving instruction according to the pressure data and the ground clearance data;

[0079] a display unit 52 connected with the control unit 51, for displaying the pressure data and the ground clearance data according to the display instruction;

[0080] a battery element 53 electrically connected with the control unit 51 and the display unit 52, for providing power for the control unit 51 and the display unit 52 respectively.

[0081] Specifically, in the embodiment, the pressure data and the ground clearance data collected by the pressure sensors 43 and the distance sensors 45 are sent to the control unit 51, the control unit 51 processes the data to generate a display instruction, the display unit 52 displays the pressure data and the ground clearance data according to the display instruction, and the user can check the parameters in the training process in real time through the display unit 52.

[0082] In the preferred embodiment of the present application, as shown in Figure 6 The control unit 51 comprises:

[0083] a storage subunit 511 for pre-storing a distance threshold, a pressure threshold and an effective number threshold;

[0084] a first comparison subunit 512 connected with the storage subunit 511, for comparing the ground clearance with the distance threshold, and generating an effective number and accumulating the effective number to the storage subunit 511 when the ground clearance is not less than the distance threshold.

[0086] The third comparison sub-unit 514 is connected to the storage sub-unit 511, and is configured to compare the pressure data with the pressure threshold, and generate a first driving instruction when the pressure data is not greater than the pressure threshold, and generate a second driving instruction when the pressure data is greater than the pressure threshold.

[0087] Specifically, in the embodiment, the user can set a distance threshold, a pressure threshold and an effective times threshold in advance. The first comparison sub-unit 512 compares the distance from the ground with the distance threshold, and indicates that the lifting height of the foot of the user reaches the preset distance threshold when the distance from the ground is not less than the distance threshold. At this time, the leg lifting action is effective, and the first comparison sub-unit 512 generates an effective times and accumulates and stores the effective times to the storage sub-unit 511. The second comparison sub-unit 513 compares the accumulated effective times with the effective times threshold, and indicates that the effective leg lifting times of the user does not reach the standard when the accumulated effective times is not greater than the effective times threshold. At this time, the second comparison sub-unit 513 generates an alarm instruction. The third comparison sub-unit 514 compares the pressure data with the pressure threshold, and indicates that the pressure applied to the upper pressure plate 42 by the user is insufficient when the pressure data is not greater than the pressure threshold. At this time, the leg strength of the user is small, and therefore the third comparison sub-unit 514 generates a first driving instruction, so that the damping device 2 outputs a force to help the lower pressure plate 44 to lift, and assists the user to complete the leg lifting action. When the pressure data is greater than the pressure threshold, it indicates that the pressure applied to the upper pressure plate 42 by the user has reached the standard for rehabilitation training. At this time, the third comparison sub-unit 514 generates a second driving instruction, so that the damping device 2 outputs a force to control the upper pressure plate 42 to press down, and helps the user to perform leg rehabilitation training.

[0088] Preferably, the direction and size of the input force of the damping device 2 can be set on the display unit 52, so that the user can adjust the training state according to the actual training situation, realize efficient and rapid training, and also can avoid that the damping device 2 always outputs excessive force to cause harm to the training process of the user.

[0089] In the preferred embodiment of the present application, the control unit 51 further comprises:

[0090] The control unit 51 further comprises:

[0091] The first processing sub-unit 515 is configured to process the pressure data and the distance data to obtain a first display instruction.

[0092] The second processing subunit 516 is connected with the second comparison subunit 513, and is configured to obtain a second display instruction according to the alarm instruction.

[0093] Specifically, in the embodiment, the display unit 52 displays the pressure data of each pressure sensor 43 and the ground clearance data of each lower pressing plate 44 according to the first display instruction; and the display unit 52 displays the state that the effective number of leg lifting of the user does not meet the standard according to the second display instruction, so as to remind the user of training and urge the user to complete the training target to ensure the rapid recovery of the leg.

[0094] In the preferred embodiment of the present application, the control assembly 5 further comprises a wireless communication module 54, which is signal-connected with the control unit 51 and electrically connected with the battery element 53, and is configured to send the pressure data and the ground clearance data to an external control terminal.

[0095] Specifically, in the embodiment, the control assembly 5 sends the pressure data and the ground clearance data to the external control terminal through the wireless communication module 54. Preferably, the external control terminal can be a work computer in a medical staff's office. Before sending the pressure data and the ground clearance data to the work computer of the medical staff, the user inputs the identity information of the user through the control unit 51 and associates the identity information with the pressure data and the ground clearance data. The medical staff can view the pressure data and the ground clearance data associated with the identity information through the work computer, and can also establish a rehabilitation training file for the patient according to the training date. Through the viewing of the rehabilitation training file, the medical staff can make some guidance suggestions for the rehabilitation training process of the user, so as to avoid the adverse effects on the recovery of the disease due to improper training.
