Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an electric walker with a built-in walking stick. Background Art

[0002] As we all know, a walker is a medical device used to assist orthopedic patients in rehabilitation. It is used by elderly people with limited mobility, some traumatic injuries, hemiplegic patients and disabled people to help them walk or exercise their limbs. Especially for orthopedic patients, a walker is an indispensable aid in the patient's rehabilitation process, so the quality of the walker will directly affect the patient's rehabilitation effect.

[0003] At present, most of the existing walkers are used to be tied to the lower limbs, and provide assistance through motors, making the originally very difficult leg steps easier. For example, a lower limb walker disclosed in patent number CN201921461406.4 mainly includes a frame (skeleton) for wearing on the patient, and then directly meshes and drives with a motor and a single gear. Although it can meet the requirements of assisted walking, the gear meshing part is exposed, which is easy to get stuck with foreign objects and not beautiful. In addition, during use, in order to avoid falling, a cane will be prepared for the patient. However, during the use of the cane, once the patient lets go or fails to hold the cane, the cane will fall directly, and it is obviously difficult for the patient to bend down to pick it up.

[0004] Therefore, it is necessary to provide a walking aid to solve these problems. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide an electric walker with a built-in walking stick.

[0022] like Figures 1 to 4 As shown, the present embodiment provides an electric walker with a built-in walking stick, comprising a waist support 1 for wearing on the waist of a human body and a thigh support 2 for wearing on the thigh of a human body, the lower end of the waist support 1 is provided with a connecting seat 3, the upper end of the thigh support 2 is provided with a connecting rod 4, the end of the connecting rod 4 is provided with a round sleeve 5, the inner ring of the round sleeve 5 is evenly provided with meshing teeth 6, the connecting seat 3 is built-in with a cylindrical cavity 7 and an arc-shaped avoidance hole 8 connected to the cavity 7, the round sleeve 5 is placed in the cavity 7, the connecting rod 4 is placed at the avoidance hole 8, the two end faces of the round sleeve 5 are fitted on the inner wall of the cavity 7, so that the round sleeve 5 can rotate relative to the connecting seat 3, and the cavity 7 is built-in There is a compartment 9, in which a motor 10 is installed. A first gear 11 is provided on the rotating shaft of the motor 10 and is placed at the center of the circular sleeve 5. The first gear 11 is meshed with the meshing teeth 6 on the circular sleeve 5 through at least one second gear 12. The waist support 1 has a built-in motherboard 13 and a battery 14 is detachably installed. The battery 14 and the motor 10 are both electrically connected to the motherboard 13. The waist support 1 is connected to a walking stick 16 through a soft rubber tube 15. The soft rubber tube 15 is a hollow tube. A key circuit board (not shown in the figure) is provided at the handshake of the walking stick 16. The key cap 17 of the key circuit board is placed outside. The key circuit board is connected to the motherboard 13 through the wiring of the soft rubber tube 15.

[0023] The present embodiment is designed to directly rotate and internally hide the motor 10 and the gears, which not only makes the exterior more streamlined and improves the aesthetic appearance, but also prevents foreign objects from affecting the normal operation of the driving components, thereby ensuring the power-assisted driving. At the same time, a walking stick 16 is connected to the soft rubber tube 15, so that the patient can carry the walking stick with him / herself, which can not only meet the use of crutches, but also prevent the walking stick 16 from falling directly after letting go, so that the patient cannot pick it up. Moreover, the button for controlling the opening and closing of the power-assisted driving is also placed on the walking stick, which can further facilitate the user to operate.

[0024] When in use, first let the patient wear the waist support 1 and the thigh support 2, and then the patient can hold the cane 16. When walking is needed, the corresponding start button on the button circuit board can be pressed to apply the start command to the main board 13. After obtaining the power of the battery 14, the motor can be driven to work. After the motor 10 is powered on, it will drive the first gear 11 to rotate forward or reverse, so that under the transmission of the second gear 12, the circular sleeve 5 will also rotate, and provide a force to the thigh support 2 to promote the activity, so as to assist the corresponding leg-stepping action. Of course, when the patient does not take the initiative to step, whether the patient will be forced to step depends mainly on the driving force of the motor 10. The power of the motor 10 is not limited in this embodiment. When there is no need for assistance, the drive of the motor 10 can also be directly turned off, and the autonomous leg-stepping walking can be directly performed. For specific use, it can be selected by the patient.

[0025] Furthermore, with regard to the structure of the waist support 1, the waist support 1 is in a "C" shape, and a first strap 18 is provided at the opening of the waist support 1, and the first strap 18 is tied and connected by a buckle 19. In addition, in order to be more comfortable to wear, an elastic inner pad 20 is provided inside the waist support 1 of this embodiment, and the specific material of the elastic inner pad 20 can be mainly composed of memory foam. In addition, in order to better fit the waist, the elastic inner pad 20 is formed with an arc surface corresponding to the shape of the human waist, so it will be more comfortable to wear.

[0026] Furthermore, the waist support 1 of this embodiment is provided with a mounting cavity 21 for placing a battery, the battery 14 is a mobile power source, the battery 14 is placed in the mounting cavity 21, and the socket of the battery 14 is placed outside the waist support 1, and the main board 13 is connected to the socket of the battery 14 through a data line 22. This design allows the battery 14 to be separated from the waist support 1, and can be replaced in time when necessary without worrying about being unable to continue to use it. It is also convenient for charging and will not be inconvenienced by the overall large volume.

[0027] Further, with respect to the thigh support 2, the thigh support 2 of this embodiment is provided with at least one second strap 23 for tying on the thigh, and the second strap 23 is connected by Velcro. In order to improve the wearing comfort, the second strap 23 of this embodiment is filled with sponge or soft colloid.

[0028] Furthermore, in order to avoid accidentally touching the key cap 17 when holding the cane, the surface of the key cap 17 on the key circuit board of this embodiment is lower than or flush with the surface of the grip of the cane 16. In this way, when the palm touches the grip of the cane 16, the occurrence of wrong operation can be effectively avoided. Of course, the key cap 17 can also be set at the front end or a place that will not be touched when holding the cane 16.

[0029] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
