[0004] The aforementioned device uses the strength of the lower limb muscles to drive the pedals, causing the springs to compress and thus achieving the training function. It can only train the patient's calves, thighs, and knee joints, and prolonged use of this device may lead to some degree of stiffness in the leg muscles. Utility Model Content

[0005] The purpose of this invention is to provide a lower limb training and rehabilitation device with a vibration structure to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lower limb training and rehabilitation device with a vibration structure, comprising a base, a bed mounted on the base, a thigh clamp mounted on the bed, a telescopic shell mounted at the end of the bed, a training mechanism mounted on the telescopic shell, the training mechanism comprising a sliding seat slidably mounted within the telescopic shell, a support arm fixedly mounted on the sliding seat, a positioning shaft fixedly mounted on the support arm, a rotating arm rotatably mounted on the positioning shaft, a foot pedal fixedly mounted on the rotating arm, and a vibration mechanism fixedly mounted on the foot pedal.

[0007] Preferably, the training mechanism further includes a torsion spring sleeved on the positioning shaft and a return spring disposed on one side of the sliding seat.

[0008] Preferably, the telescopic housing has a sliding groove, and the sliding seat is slidably mounted on the telescopic housing through the sliding groove.

[0009] Preferably, the rotating arm has a movable hole, and the rotating arm is rotatably mounted on the positioning shaft through the movable hole. One end of the torsion spring is connected to the positioning shaft, and the other end of the torsion spring is connected to the positioning shaft. One end of the return spring is connected to the sliding seat, and the other end of the return spring is connected to the inner wall of the telescopic housing. The foot pedal is rotatably mounted on the positioning shaft through the rotating arm, and the support arm is slidably mounted on the telescopic housing through the sliding seat.

[0010] Preferably, the vibration mechanism includes a mechanism housing fixedly mounted on a foot pedal, a motor fixedly mounted on the mechanism housing, a metal block fixedly mounted at the end of the mechanism housing and fixedly mounted on the foot pedal, an impact block rotatably mounted inside the mechanism housing, an eccentric disk fixedly mounted at the output end of the motor, a connecting rod between the eccentric disk and the impact block, and rotating shafts mounted at both ends of the connecting rod.

[0011] Preferably, the housing of the mechanism has a through hole, and the output end of the motor extends into the housing of the mechanism through the through hole.

[0012] Preferably, the eccentric disk is rotatably mounted inside the mechanism housing via a motor, one end of the connecting rod is rotatably mounted on the impact block via a rotating shaft, and the other end of the connecting rod is rotatably mounted on the eccentric disk via a rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this application, as the user pushes the foot pedal forward, the support arm drives the sliding seat to move forward accordingly. During the forward movement of the sliding seat, the return spring applies resistance, requiring the user to overcome this resistance through the coordinated action of the thigh and calf muscles, thus enabling the foot pedal to move forward. This action can train the user's thighs, calves, and knee joints. Furthermore, when the user rotates their ankle, the rotating arm rotates accordingly, and the torsion spring applies resistance to the rotating arm, requiring the user to overcome this resistance through the strength of their ankle, thereby achieving the purpose of specific training for the ankle joint.

[0015] In this application, after the motor starts, it drives the eccentric disk to rotate. Subsequently, the rotation of the eccentric disk drives the connecting rod, causing the impact block to perform a reciprocating forward and backward motion. During this process, the impact block applies periodic impacts to the metal block, thereby inducing foot pedal vibration. This vibration is transmitted to the lower limbs through the foot pedal, stimulating vasodilation, promoting the clearance of metabolic waste, and helping to relieve muscle stiffness after exercise.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a lower limb training and rehabilitation device with a vibration structure, including a base 1, a bed 2 mounted on the base 1, a thigh clamp arm 3 mounted on the bed 2, a telescopic shell 4 mounted at the end of the bed 2, a training mechanism 5 mounted on the telescopic shell 4, and a vibration mechanism 6 fixedly mounted on the foot pedal 505. The training mechanism 5 can train the patient's calves, knee joints, and ankles, and the vibration mechanism 6 can alleviate muscle stiffness after exercise.

[0023] like Figure 2 and Figure 3 As shown, the training mechanism 5 includes a sliding seat 501 slidably installed in the telescopic housing 4, a support arm 503 fixedly installed on the sliding seat 501, a positioning shaft 506 fixedly installed on the support arm 503, a rotating arm 504 rotatably installed on the positioning shaft 506, and a foot pedal 505 fixedly installed on the rotating arm 504. The training mechanism 5 also includes a torsion spring 507 sleeved on the positioning shaft 506 and a return spring 502 provided on one side of the sliding seat 501. A sliding groove is provided in the telescopic housing 4, and the sliding seat 501 is slidably installed on the telescopic housing 4 through the sliding groove.

[0024] Specifically, when the foot pedal 505 moves forward, the support arm 503 moves accordingly, guiding the sliding seat 501 forward. During the forward movement of the sliding seat 501, the return spring 502 applies resistance to the sliding seat 501, requiring the user to use the strength of their calves and thighs to propel the foot pedal 505 forward. This movement mechanism effectively trains the user's calf and thigh muscles and knee joint. Simultaneously, the user can also rotate their ankle; when rotating the ankle, the rotating arm 504 on the foot pedal 505 also rotates. To increase the difficulty of the training, the torsion spring 507 applies additional resistance to the rotating arm 504, requiring the user to use the strength of their ankle to overcome the resistance of the torsion spring 507 to rotate the foot pedal 505. In this way, the flexibility and strength of the patient's ankle can be effectively trained.

[0025] like Figure 2 and Figure 4 As shown, the vibration mechanism 6 includes a mechanism housing 601 fixedly mounted on the foot pedal 505, a motor 606 fixedly mounted on the mechanism housing 601, a metal block 602 fixedly mounted at the end of the mechanism housing 601 and fixedly mounted on the foot pedal 505, an impact block 603 rotatably mounted inside the mechanism housing 601, an eccentric disk 605 fixedly mounted at the output end of the motor 606, a connecting rod 604 between the eccentric disk 605 and the impact block 603, a rotating shaft 607 mounted at both ends of the connecting rod 604, and a through hole opened on the mechanism housing 601, through which the output end of the motor 606 extends into the mechanism housing 601.

[0026] Specifically, when the motor 606 is started, it drives the eccentric disc 605 to rotate. As the eccentric disc 605 rotates, the connecting rod 604 moves accordingly, which in turn drives the impact block 603 to move back and forth reciprocally. During the reciprocating motion of the impact block 603, it applies a continuous impact force to the metal block 602. This impact force causes the foot pedal 505 to vibrate, and this vibration is transmitted to the lower limbs through the foot pedal 505. In this way, it can stimulate the dilation of blood vessels in the lower limbs, accelerate the elimination of metabolic waste, and thus effectively relieve muscle stiffness that may occur after exercise.

[0027] Working principle: When in use, the user lies on the bed 2 and places both feet in the foot pedal 505. After the user's feet are in the foot pedal 505, the user can push the foot pedal 505 forward by the coordinated action of the upper and lower legs. After the foot pedal 505 moves forward, the support arm 503 will drive the sliding seat 501 to move forward. During the forward movement of the sliding seat 501, the return spring 502 will apply a certain resistance to the sliding seat 501, so that the user needs to exert force with the upper and lower legs to push the foot pedal 505 forward, thereby training the user's upper and lower legs and knee joints. At the same time, the user can rotate the ankle. When the ankle is rotated, it will drive the rotating arm 504 on the foot pedal 505 to rotate. The torsion spring 507 will apply a certain resistance to the rotating arm 504, so that the user needs to exert force with the ankle to drive the foot pedal 505 to rotate, thereby training the patient's ankle. Furthermore, the motor 606 can be started during training. After the motor 606 is started, it will drive the eccentric disk 605 to rotate. After the eccentric disk 605 rotates, the connecting rod 604 will drive the impact block 603 to move back and forth. When the impact block 603 moves back and forth, it will impact the metal block 602, thereby causing the foot pedal 505 to vibrate. The vibration of the foot pedal 505 will be transmitted to the lower limbs, thereby stimulating vasodilation, accelerating the removal of metabolic waste, and relieving muscle stiffness after exercise.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
