Description

Technical Field

[0001] This application belongs to the field of cane technology, and more specifically, relates to an assistive cane and an assistive device. Background Technology

[0002] Existing crutches (underarm crutches, trekking poles, elbow crutches, walking sticks, etc.) can be broadly categorized into standard, smart, and sports types. Their main functions are body support, walking assistance, support for professional sports, and recovery aid. They are characterized by their sturdiness, comfort, and lightweight nature. However, they lack power.

[0003] During regular mountain climbing, one might crave a push from back to front when going uphill and a push from front to back when going downhill. However, ordinary walking sticks cannot provide comfortable assistance, and one can only rely on their own muscles to coordinate and assist.

[0004] Lower limb exoskeletons can provide this assistive function through strapping and sensor actuators, but they are heavy, bulky, inflexible, and expensive.

[0005] Existing trekking poles or canes can assist in going up and down stairs, but they require upper limb strength, which can cause wear and tear on the hands or armpits over time. They also require upper limb strength and do not save effort in the process; they only provide a more stable body posture. Utility Model Content

[0046] Please refer to the following: Figure 1 and Figure 2 The following describes the assistive cane provided in the embodiments of this application. The assistive cane includes a rocker arm 100, a first support rod 200, a swing connector 300, a telescopic drive member 400, and a second support rod 500. The first end of the first support rod 200 is mounted on the rocker arm 100; the swing connector 300 is hinged to the rocker arm 100; one end of the telescopic drive member 400 is connected to the rocker arm 100; the other end of the telescopic drive member 400 is connected to the swing connector 300; the first end of the second support rod 500 is connected to the swing connector 300; and the second end of the second support rod 500 is used to support the ground.

[0047] Compared with the prior art, the assistive cane provided in this application embodiment, through the cooperation of rocker arm 100, swing connector 300 and telescopic drive member 400, the second support rod 500 contacts the ground, the first support rod 200 is held by the user, and when the telescopic drive member 400 is extended, it transmits an upward or forward external force to the user through rocker arm 100 and first support rod 200 to reduce the burden on the user's legs, knees and back, thereby playing a protective role for the lower limbs when going up and down mountains or stairs, and making going up and down mountains and stairs easier and less strenuous.

[0048] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2The assistive cane also includes a first diagonal pull rod 610, the first end of which is connected to the rocker arm 100, and the second end of which is connected to the first support rod 200. The connection between the first diagonal pull rod 610 and the first support rod 200 is close to the second end of the first support rod 200.

[0049] In this embodiment, by setting the first diagonal tie rod 610, the rocker arm 100, the first support rod 200, and the first diagonal tie rod 610 form a triangular structure, which can further enhance the stability between the rocker arm 100 and the first support rod 200. This ensures that when the cane is working, the connection between the rocker arm 100 and the first support rod 200 will not experience unnecessary shaking or twisting, thereby improving the reliability of the overall structure. The setting of the first diagonal tie rod 610 reduces the force on the rocker arm 100 and the first support rod 200, thereby reducing the strength requirements of the materials of the rocker arm 100 and the first support rod 200, and thus reducing the cost of raw material selection.

[0050] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The assistive cane also includes an armpit support 710, which is installed at the second end of the first support rod 200; the first end of the first diagonal pull rod 610 is connected to the rocker arm 100, and the second end of the first diagonal pull rod 610 is connected to the armpit support 710.

[0051] In this embodiment, the armpit support 710 provides additional support to the user's armpits, reducing pressure on the armpits and arms and making prolonged use of the cane more comfortable. The armpit support 710 is designed with ergonomic principles in mind, adapting to different user body sizes and providing a personalized support experience, thus improving user comfort.

[0052] In this embodiment, the closer the connection between the first diagonal tie rod 610 and the first support rod 200 is to the end of the second end of the first support rod 200, the smaller the force on the first support rod 200. Therefore, when the second end of the first diagonal tie rod 610 is connected to the armpit support 710, the radial force on the first support rod 200 is minimal.

[0053] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The assistive cane also includes a first straight pull rod 810, which is arranged parallel to the first support rod 200; the first end of the first straight pull rod 810 is connected to the rocker arm 100, and the second end of the first straight pull rod 810 is connected to the armpit support 710.

[0054] In this embodiment, the first straight pull rod 810 serves as an auxiliary positioning element for the first support rod 200, ensuring its stability during use and preventing wobbling caused by uneven ground or improper user operation. The first straight pull rod 810 makes the entire assistive cane structure more stable, enhancing the user's sense of security and stability during use.

[0055] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The assistive cane also includes a second diagonal pull rod 620. The first end of the second diagonal pull rod 620 is connected to the swing connector 300, and the second end of the second diagonal pull rod 620 is connected to the second support rod 500. The connection between the second diagonal pull rod 620 and the second support rod 500 is close to the second end of the second support rod 500.

[0056] In this embodiment, the second diagonal brace 620 further enhances the stability between the swing connector 300 and the second support rod 500, ensuring that the connection between the swing connector 300 and the second support rod 500 does not experience unnecessary shaking or twisting when the cane is in operation, thereby improving the overall structural reliability. The second diagonal brace 620 reduces the stress on the swing connector 300 and the second support rod 500, thus reducing the strength requirements of the materials for the swing connector 300 and the second support rod 500, and consequently reducing the cost of raw material selection.

[0057] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The assistive cane also includes a support base 900, which is installed at the second end of the second support rod 500; the first end of the second diagonal rod 620 is connected to the swing connector 300, and the second end of the second diagonal rod 620 is connected to the support base 900.

[0058] In this embodiment, by setting the support base 900, additional support can be provided for the second support rod 500 to ensure the stability of the second support rod 500 when it contacts the ground.

[0059] In one embodiment of this application, please refer to the following: Figure 1 and Figure 7 The end of the support base 900 away from the second support rod 500 is an arc surface 901, which is used to support the ground; the side of the support base 900 is provided with a tie rod fixing hole 902, which is close to the arc surface 901, and is used to install the second diagonal tie rod 620.

[0060] In this embodiment, the design of the support base 900 takes into account adaptability to different ground conditions. Its arc surface 901 can better adapt to uneven ground, reduce impact on the ground, and provide stable support. In addition, the tie rod fixing hole 902 on the side of the support base 900 can easily install the second diagonal tie rod 620, making the structure more compact and stable.

[0061] In this embodiment, the closer the connection between the second diagonal tie rod 620 and the first support rod 200 is to the end of the second support rod 500, the smaller the force on the second support rod 500. Therefore, when the second end of the second diagonal tie rod 620 is connected to the tie rod fixing hole 902 of the support base 900, the force on the first support rod 200 is minimal.

[0062] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The assistive cane also includes a second straight pull rod 820, which is arranged parallel to the second support rod 500; the first end of the second straight pull rod 820 is connected to the swing connector 300, and the second end of the second straight pull rod 820 is connected to the support base 900.

[0063] In this embodiment, the second straight pull rod 820 is provided to assist in positioning the second support rod 500, ensuring its stability during use and preventing wobbling caused by uneven ground or improper user operation. The second straight pull rod 820 makes the entire assistive cane structure more stable, improving the user's sense of security and stability during use.

[0064] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The assistive cane also includes a handle 720, which is mounted on the rocker arm 100.

[0065] In this embodiment, by providing a handle 720, the user can grip the cane more stably, offering a stable grip point and improving ease of use and safety. The shape and material of the handle 720 can be optimized according to the user's hand shape and gripping habits to provide the best grip experience. By designing the handle 720, the cane becomes more ergonomic, enhancing user comfort.

[0066] In one embodiment of this application, the telescopic drive 400 is any one of an electric push rod, a pneumatic cylinder, and a hydraulic cylinder.

[0067] In this embodiment, the electric push rod, cylinder, and hydraulic cylinder can all achieve linear reciprocating motion, thereby enabling the rocker arm 100 and the swing connector 300 to swing relative to each other. The telescopic drive 400 can automatically adjust the assist force according to the user's walking speed and terrain changes, ensuring that the user receives stable assistance support in different situations. This automatic adjustment function greatly improves the applicability and safety of the cane.

[0068] In one implementation of this application, please refer to the following: Figure 3 and Figure 4 The rocker arm 100 is also provided with a first connector 101, a first inclined pull fixing hole 102 and a first straight pull fixing hole 103. The first connector 101 is used to connect the first support rod 200, the first inclined pull fixing hole 102 is used to install the first inclined pull rod 610, and the first straight pull fixing hole 103 is used to install the first straight pull rod 810. The swing connector 300 is provided with a second connector 301, a second inclined pull fixing hole 302 and a second straight pull fixing hole 303. The second connector 301 is used to connect the second support rod 500, the second inclined pull fixing hole 302 is used to install the second inclined pull rod 620, and the second straight pull fixing hole 303 is used to install the second straight pull rod 820.

[0069] The assistive cane provided in this application embodiment can be used by disabled or elderly people, for example, in scenarios such as sitting down and standing up from a chair or commode, the assistive cane can be used to provide assistance, and can effectively assist vertical movement in a limited space. This function cannot be conveniently provided by ordinary canes and existing exoskeletons.

[0070] The assistive crutch provided in this application embodiment can also be used as a trekking pole. When climbing, the assistive crutch can provide thrust from the ground behind or to the side, reducing the weight borne by the knees and making climbing or ascending stairs easier. When descending, the invention can provide counter-thrust from the ground in front, reducing the force of active knee flexion, making descending or descending stairs easier and more controllable. The assistive crutch, through underarm support and hand grip, effectively avoids complex exoskeleton binding designs and allows for efficient control and use.

[0071] This application also provides an assistive device; please refer to [link / reference]. Figure 8 The assistive device includes a connecting component 20, a connector, and two assistive canes 10 as described above; the two ends of the connecting component 20 are respectively connected to the two assistive canes 10 through the connector.

[0072] The purpose of the connecting component 20 in this embodiment is to prevent the weight of the two assistive canes 10 from being applied to the user's body by providing alternating support.

[0073] The assistive device of this application connects two assistive canes 10 together through the connecting part 20 and the connector to form a whole, making the user more stable when using it, especially in situations that require extra balance and support, such as climbing mountains or walking on uneven ground.

[0074] In this embodiment, by incorporating an assistive device including a connecting component 20, a connector, and two assistive canes 10, the two canes 10 can work together to provide the user with more balanced and stable support. The design of the connecting component 20 and the connector makes the entire assistive device more compact, while also facilitating disassembly, carrying, and storage. Furthermore, the simultaneous use of the two assistive canes 10 can further reduce the user's burden, especially in situations requiring greater assistance, such as climbing mountains or stairs, significantly improving the user's mobility.

[0075] Example 1

[0076] Please refer to the following in this embodiment: Figure 1 and Figure 2 The swing connector 300 is a swing arm structure. The connection point between the swing arm structure and the swing connector 300 is located between the connection point between the second support rod 500 and the swing connector 300 and the connection point between the second tie rod 620 and the swing arm structure.

[0077] In this embodiment, the connection point between the swing arm structure and the swing connector 300 is located between the connection point between the second support rod 500 and the swing connector 300 and the connection point between the second tie rod 620 and the swing arm structure. This increases the lever arm length of the telescopic drive member 400 on the swing connector 300, reduces the rotational efficiency of the swing connector 300, and makes the telescopic drive member 400 less labor-intensive. The maximum included angle between the first support rod 200 and the second support rod 500 can reach 15°-30°.

[0078] In this embodiment, the swing arm structure is rod-shaped, and the connection points of the swing arm structure and the swing connector 300, the connection points of the second support rod 500 and the swing connector 300, and the connection points of the second tie rod 620 and the swing arm structure are on the same straight line.

[0079] Example 2

[0080] Please refer to the following in this embodiment: Figure 3 and Figure 4 The swing connector 300 is a swing arm structure. The connection point between the telescopic drive 400 and the swing connector 300 is located between the connection point between the second support rod 500 and the swing arm structure and the connection point between the second tie rod 620 and the swing arm structure.

[0081] In this embodiment, the connection point between the telescopic drive member 400 and the swing connector 300 is located between the connection point between the second support rod 500 and the swing arm structure and the connection point between the second tie rod 620 and the swing arm structure. This reduces the lever arm length of the telescopic drive member 400 on the swing connector 300, improving the rotation efficiency of the swing connector 300 but requiring more effort. It also increases the maximum bending angle between the first support rod 200 and the second support rod 500, with the maximum included angle between the first support rod 200 and the second support rod 500 reaching 65°-90°.

[0082] In this embodiment, the swing arm structure is plate-shaped, and the connection points between the swing arm structure and the swing connector 300, the connection points between the second support rod 500 and the swing connector 300, and the connection points between the second tie rod 620 and the swing arm structure are distributed in a triangular pattern. Please refer to [link / reference]. Figure 5 Side bearings 110 are provided on two opposite sides of the swing arm structure for rotating connection between the swing arm structure and the rocker arm 100. By providing side bearings 110, the stability of the swing arm structure relative to the rocker arm 100 can be improved.

[0083] Example 3

[0084] In this embodiment, please refer to Figure 6 The swing connector 300 includes a chain 310, a sprocket 320, and a spring; the first end of the chain 310 is connected to the telescopic drive 400; the sprocket 320 meshes with the chain 310 and is rotatably mounted on the rocker arm 100; the first end of the second support rod 500 is connected to the end face of the sprocket 320; the first end of the spring is connected to the second end of the chain 310 and the second end of the spring is connected to the rocker arm 100.

[0085] In this embodiment, by providing a swing connector 300, including a chain 310, a sprocket 320, and a spring, flexible swinging between the rocker arm 100 and the swing connector 300 can be achieved. Simultaneously, the elasticity of the spring not only serves a restoring function but also keeps the chain 310 constantly taut, preventing separation between the chain 310 and the sprocket 320. The combination of the chain 310 and the sprocket 320 makes the movement of the swing connector 300 smoother, improving the efficiency and comfort of using the cane.

[0086] In this embodiment, please refer to Figure 6The first end of the chain 310 is provided with a first fixing hole 311, which is used to install the telescopic drive component 400; the second end of the chain 310 is provided with a second fixing hole 312, which is used to install a spring; the sprocket 320 is provided with a shaft hole 321, a first connecting hole 322, and a second connecting hole 323; a rotating shaft is fixed on the shaft hole 321, and the rotating shaft is rotatably connected to the rocker arm 100; the first connecting hole 322 is used to install the first support rod 200, and the second connecting hole 323 is used to install the second diagonal tie rod 620.

[0087] In this embodiment, the working principle of the swing connector 300 is as follows: When the telescopic drive 400 retracts, it pulls the chain 310 to move, the chain 310 meshes with the sprocket 320, and drives the sprocket 320 to rotate, thereby causing the second support rod 500 mounted on the sprocket 320 to swing relative to the rocker arm 100. At this time, the spring is in a stretched state. When the telescopic drive 400 extends, the spring retracts, and the chain 310 moves in the opposite direction under the elastic force of the spring, thereby driving the sprocket 320 to rotate in the opposite direction, thereby driving the second support rod 500 mounted on the sprocket 320 to swing in the opposite direction relative to the rocker arm 100, thus achieving a reset.

[0088] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
