DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0017] As Figures 1 to 3As shown in the figure, the present utility model provides an electric walking aid, which includes a backboard 1. A battery 4 is installed on the back surface of the backboard 1. The battery 4 is used to provide power for the electric components. A waist fixing frame 2 is fixedly connected to the bottom end of the backboard 1. When a person uses it, the waist fixing frame 2 is fixed to the person's waist. The backboard 1 is located on the person's back. Two fixing straps 3 are provided on both the backboard 1 and the waist fixing frame 2. The backboard 1 and the waist fixing frame 2 can be fixed to the person's waist through the fixing straps 3. Fixing cylinders 8 are fixedly connected to both bottom ends of the waist fixing frame 2. A swing plate 7 is rotatably sleeved on the surface of each fixing cylinder 8, so that the top end of the swing plate 7 can swing on the fixing cylinder 8. A leg fixing sleeve 9 is fixedly connected to the bottom end of each swing plate 7. An elastic band is provided on the leg fixing sleeve 9 to facilitate the fixed wearing of the person. A swing rod mechanism for driving the swing of the swing plate 7 is provided in each fixing cylinder 8. With the setting of the swing rod mechanism, the swing of the swing plate 7 is driven, and the leg fixing sleeve 9 drives the person's leg to swing, thereby realizing the auxiliary walking of the person's leg by this device. Moreover, this device has a compact structure and simple operation, improving the practicability. The machinery, parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
[0018] As Figure 1 shown, two lifting rods 5 are installed at the top end of the backboard 1. A neck rest 6 is fixedly connected to the top ends of the two lifting rods 5. With the setting of the above structure, the neck of the person can be supported, improving the comfort of the person during use. At the same time, the neck rest 6 can also support the person's head for use, making the use more flexible.
[0019] As Figure 1 shown, a knee protection sleeve 10 is fixedly connected to the bottom end of each leg fixing sleeve 9. With the setting of the knee protection sleeve 10, the knee of the person can be protected.
[0020] As Figure 2 and Figure 3As shown in the figure, the swing rod mechanism includes a motor 101 installed in a fixed cylinder 8 and a fixed plate 102 fixed in the fixed cylinder 8. The motor 101 is electrically connected to the battery 4. The fixed plate 102 is located in front of the motor 101. The output end of the motor 101 passes through the fixed plate 102 and is fixedly connected with a rotating plate 105. A bushing 104 is rotatably connected to the top end of the rotating plate 105. The bushing 104 can be driven to swing by the operation of the motor 101. A swing shaft 106 is slidably arranged in the bushing 104, so that the bushing 104 is sleeved on the surface of the swing shaft 106. The top end of the swing shaft 106 is fixedly connected with a rotating shaft 103, and one end of the rotating shaft 103 is rotatably connected to the top end of the fixed plate 102. The bottom end of the swing shaft 106 is fixedly connected with a connecting rod 107, and the connecting rod 107 is connected to the back surface of the swing plate 7. Through the above structural arrangement, the rotation of the rotating plate 105 can be driven by the operation of the motor 101, and further the bushing 104 drives the swing shaft 106 to swing, so that the swing shaft 106 swings reciprocally around the rotation point of the rotating shaft 103, realizing the swing of the connecting rod 107 driving the swing plate 7 and the leg fixing sleeve 9, and thus the swing of the leg fixing sleeve 9 is used to assist the swing walking of the person's legs, improving the practicability of the device.
[0021] As Figure 2 , Figure 3 shown in the figure, the rotating plate 105 is slidably arranged on the front surface of the fixed plate 102, so that the rotation of the motor 101 can normally drive the rotating plate 105 to swing. The output end of the motor 101 is fixedly connected to the bottom end of the rotating plate 105, and the output end of the motor 101 does not contact the fixed plate 102.
[0022] The working principle and usage process of the present utility model are as follows: First, place the back plate 1 on the back of the user, and support the waist fixing frame 2 on the user's waist, so that the two fixed cylinders 8 are respectively located on both sides of the waist. Then, use two groups of fixing belts 3 to fix the device on the user. Next, wrap the two leg fixing sleeves 9 and the two knee guards 10 around the two thighs of the user respectively. Finally, use the motors 101 to operate at opposite frequencies to drive the rotating plate 105 to swing, further driving the bushing 104 to swing around the top end of the rotating plate 105. The bushing 104 will slide up and down on the swing shaft 106 and drive the swing shaft 106 to swing around the rotating shaft 103 together, so that the connecting rod 107 drives the swing plate 7 and the leg fixing sleeve 9 to swing, and the two leg fixing sleeves 9 with different frequencies drive the two legs of the user to swing assistingly, which is beneficial to the walking rehabilitation of the user.
