Technical Field

[0001] The present invention relates to the technical field of rehabilitation training equipment, and in particular to a gait rehabilitation training device. Background Art

[0002] More and more people are suffering from lower limb injuries due to diseases or accidents, and severe cases may even cause paralysis.

[0003] Patients with lower limb injuries require long-term gait rehabilitation training. Gait rehabilitation training is a common rehabilitation training method, mainly used to help people restore walking ability and stability. For some people with severe lower limb injuries, they need to use rehabilitation training equipment to assist them in gait rehabilitation training. Gait rehabilitation training equipment can also be used to prevent falls and improve the quality of life. For some elderly or high-risk patients, their balance ability and reaction speed may decline, making them prone to falls. By using gait rehabilitation training equipment, they can be helped with balance training and reaction training, improve their balance ability and reaction speed, and reduce the risk of falls.

[0004] There are various gait rehabilitation training devices on the market. Among them, there is a gait rehabilitation trainer that can be used as a wheelchair. When the patient wants to stand up for gait rehabilitation training, the seat plate on the device can drag the patient's buttocks upward to assist him to stand up, and the standing patient can be lifted by the straps to prevent the patient's body weight from acting on the legs, which can assist the patient to stand up for gait rehabilitation training. However, the device also has the following problems: the patient needs someone to help him put on the straps, which makes it difficult for the patient to stand up for gait rehabilitation training alone, and it is difficult for the patient to use it alone. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem mentioned in the above background technology that patients need someone to help them put on the straps, which makes it difficult for patients to stand up and perform gait rehabilitation training alone, and it is difficult for patients to use it alone.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A gait rehabilitation training device includes a chair body, which is composed of a chair frame, a seat board and an unfolding mechanism. The seat board is composed of board one and board two. The unfolding mechanism is arranged on the chair frame and connected to the seat board. The unfolding mechanism is used to rotate the seat board and push the patient's buttocks upward. The synchronous component is arranged on the chair frame and connected to the unfolding mechanism and the seat. The synchronous component includes a lifting component. The lifting component is located below board two and connected to board two. The lifting component is used to synchronously move board two upward.
