Abstract
Description
Technical Field
[0001] The present invention relates to the field of nursing devices, and in particular to a nursing device for assisting walking. Background Art
[0002] As an important medical rehabilitation device to improve mobility and enhance the quality of life, the market demand for assisted walking care devices has shown a significant upward trend. Existing assisted walking devices mainly include crutches, walkers (four-legged frame type, wheeled type), wheelchairs and walking assistance vehicles. The core function of this type of assisted walking device is to provide support to users through mechanical structures, share body weight, reduce the risk of falling, and help users complete basic movements such as standing and walking. However, existing products still have many limitations in structural design, especially in terms of the convenience and adaptability of height adjustment and width adjustment. The technical bottleneck has not been broken through for a long time, resulting in poor user experience.
[0003] In response to the above problems, a Chinese patent (patent publication number: CN215021800U) discloses a telescopic walking assist device for outpatient nursing, including a lifting frame and a connecting mechanism. There are two lifting frames, which are arranged symmetrically on the left and right, and the rear ends of the two lifting frames are connected by a connecting mechanism; the lifting frame includes a first telescopic rod, a second telescopic rod and a Z-shaped connecting rod; a first transverse sleeve is provided on the upper part of the first telescopic rod, and a first L-shaped rod is inserted into the end of the first transverse sleeve away from the first telescopic rod. The end of the first L-shaped rod close to the first transverse sleeve is fixed to the first transverse sleeve by a first adjusting knob, and the end away from the first transverse sleeve is vertically upward; one end of the Z-shaped connecting rod is fixed to the upper end of the second telescopic rod, and the other end is provided with a first vertical sleeve, which is sleeved on the outside of the end of the first L-shaped rod away from the first transverse sleeve and rotates with it.
[0004] Although the above-mentioned walking assist device can achieve height and width adjustment through the first telescopic rod, the second telescopic rod, the third telescopic rod and the fourth telescopic rod, its adjustment method is relatively complicated, and the height difference of the adjustment position is large. For users who have limited mobility, they need the assistance of the auxiliary walking device, so it is not convenient for users with limited mobility to use it independently, and it requires simultaneous adjustment of multiple sides. Its adjustment is relatively inconvenient, resulting in the need for assistance from family members or medical staff during use. Summary of the Invention
[0005] The present invention aims to provide a walking assistance nursing device, which solves the problem that the existing walking assistance nursing devices are not convenient for users to adjust their height and width independently.
[0006] In order to achieve the above object, the technical solution of the present invention is as follows: an auxiliary walking care device, comprising:
[0007] Two bases, the two bases are arranged in parallel and spaced apart;
[0008] Four universal wheels, the four universal wheels are symmetrically arranged at the bottom of the two bases;
[0009] Two limiting rods, the two limiting rods are respectively arranged on corresponding bases;
[0010] A connecting rod, wherein guide holes for sliding connection with corresponding limit rods are provided on both sides of the connecting rod, and the connecting rod is slidably connected between the two bases;
[0011] Two lifting assemblies, each of which is provided on a corresponding base and capable of achieving a lifting function;
[0012] Two support blocks, each of which is arc-shaped;
[0013] Two limiting grooves, the two limiting grooves are respectively opened on the corresponding support blocks;
[0014] The limiting plate is arc-shaped and is slidably connected in at least one limiting groove. The limiting plate and the two limiting grooves are on the same circular ring.
[0015] Furthermore, the lifting assembly includes four electric telescopic rods, which are symmetrically arranged on both sides of each base, each of the electric telescopic rods is rotatably connected to a top rod, and the other end of each top rod is rotatably connected to a first lifting link, one end of the two first lifting links is rotatably connected to the corresponding base through a first pin shaft, and the other end of each first lifting link is rotatably connected to a second lifting link through a second pin shaft, and the other ends of the two second lifting links directly above each base are rotatably connected through a third pin shaft, and a support column is provided on the third pin shaft, and the two support columns are slidably connected to the support block.
[0016] Through the above arrangement, the electric telescopic rod can drive the top rod to move back and forth in the horizontal direction. After the top rod moves, the first lifting link can drive the second lifting link to rotate, thereby realizing the lifting of the support block and the limit plate, and realizing long-distance vertical lifting through short-distance horizontal movement, which can be suitable for a wider range of users.
[0017] Furthermore, a first sliding groove is formed at the bottom of each support block, and the support column is slidably connected in the first sliding groove.
[0018] Through the above arrangement, the first sliding groove can ensure the stability of the sliding of the support column, thereby enhancing the stability of the adjustment process of the support block and the limit plate.
[0019] Furthermore, the limiting plate is flush with the upper surface of the limiting groove.
[0020] Through the above arrangement, when the user needs to sit down and rest, the user can slide the limit plate into the limit groove on the corresponding side, so that the support block and the limit plate can form a support surface with a larger width, thereby realizing the function of the user sitting and resting without adding obstructions or occupying walking space.
[0021] Furthermore, the arc length of each support block is less than one quarter of the circumference of the circular ring where the support block is located, and the arc length of the limiting plate is not less than three quarters of the circumference of the circular ring where the limiting plate is located.
[0022] Through the above arrangement, no matter how the support block is adjusted, it can be ensured that the limiting plate is located in the limiting groove of at least one support block.
[0023] Furthermore, a support spring is connected between the two first lifting links or the two second lifting links on the same side.
[0024] Through the above-mentioned setting, the support spring can provide a certain buffering and supporting effect on the support block and the lifting link when any pin shaft breaks, which is beneficial for the user to provide timely protection and effectively reduces the possibility of user injury caused by accidental damage between the lifting links.
[0025] Furthermore, each of the first lifting links is rotatably connected to a rubber block with one end located below the base.
[0026] Through the above arrangement, when the first lifting link rotates to a predetermined position, the rubber block can come into contact with the ground, thereby increasing the friction between the device and the ground with the help of the user's own weight and the rubber block, thereby improving the stability and reliability of the device when the user is sitting or resting.
[0027] Furthermore, a handle is provided on the limiting plate.
[0028] Through the above arrangement, the user can conveniently adjust the position of the limit plate with the help of the handle. At the same time, it is also helpful for the user to maintain balance by using the handle when sitting or standing.
[0029] Furthermore, the handle is provided with a control button electrically connected to the four electric telescopic rods.
[0030] Through the above arrangement, the user can conveniently control the lifting and lowering of the support block and the limiting plate with the help of the control button.
[0031] Compared with the existing technology, this solution has the following beneficial effects:
[0032] 1. This solution uses an electric telescopic rod to drive the top rod and the lifting link to rotate. Through the linkage mechanism of the top rod and the lifting link, short-distance horizontal movement is converted into long-distance vertical lifting. In addition, the user only needs to use the control button on the handle to adjust the height. The user does not need to manually operate multiple parts or rely on others to complete the height adjustment. This greatly simplifies the adjustment process and is especially suitable for people with limited mobility to operate independently.
[0033] 2. This solution uses the ingenious design of the support block and the limit plate. By sliding the limit plate in the limit groove, a wider arc-shaped support surface can be quickly formed. This not only retains the basic function of assisting walking, but also adds the practical function of sitting, standing and resting. It does not require additional space or adding obstructions, and takes into account both mobility assistance and daily life needs.
[0034] 3. A support spring is added between the lifting links of this solution, which can provide buffer support for the support block in the event of accidental breakage. At the same time, the user's own weight is used to cooperate with the rubber block to increase the friction against the ground, effectively reducing the risk of failure of the device or tipping over during sitting or standing, and improving safety of use.
[0035] 4. Through mechanical structure optimization and functional integration, this device significantly enhances user autonomy, adaptability to different scenarios, and reliability while maintaining lightweight and portability, providing a more humane and multifunctional care solution for people with mobility impairments. Furthermore, through innovative structural design, it demonstrates significant advantages in ease of adjustment, functional scalability, and safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0041] The present invention will be further described in detail below through specific embodiments:
[0042] Example
[0043] like Figures 1 to 4 As shown, a walking assistance nursing device comprises:
[0044] Two bases 1, each of which is a rectangular structure, are arranged parallel to each other and spaced apart. Each base 1 is provided with a through slot extending through the upper and lower surfaces of the base 1, and grooves are provided on the front and rear inner walls of the through slot. A second slide slot is provided on the opposite side of each base 1.
[0045] Four universal wheels 2 are symmetrically arranged at the bottom of the two bases 1 , and each universal wheel 2 is bolted to the bottom of the corresponding base 1 .
[0046] Two limiting rods 3, the two limiting rods 3 are respectively arranged in the second sliding groove of the corresponding base 1
[0047] The connecting rod 4 has guide holes on both sides thereof which are slidably connected to the corresponding limit rods 3. The connecting rod 4 is slidably connected between the two second slide grooves. With the help of the connecting rod 4, the connection between the two bases 1 can be maintained. At the same time, the sliding connecting rod 4 can realize the function of both the left and right sides entering between the support block 15 and the limit plate 18, which greatly improves the convenience of use for users.
[0048] Two lifting assemblies, each mounted on a corresponding base 1, enable lifting. The lifting assemblies include four electrically operated telescopic rods 5, symmetrically positioned on either side of two through-slots. Each rod 5 has a push rod 6 extending through its free end, which slides between two grooves. Each push rod 6 is rotatably connected to a push rod 7, one end of which is integrally formed with a connecting ring 8 that wraps around the push rod 6. The other end of each push rod 7 is rotatably connected to a first lifting link 9. The sidewall of each first lifting link 9 has a groove defined therein. The push rod 7 rotates within the groove via a fourth pin and is rotatably connected to the center of the first lifting link 9. A fixed rod 10 is rotatably connected to the underside of each first lifting link 9 via a fifth pin. A rubber block 11, located below the base 1, is attached to the bottom of the fixed rod 10. This rubber block 11 is designed to contact the ground after the first lifting link 9 rotates to a predetermined position, thereby increasing friction between the device and the ground and maintaining its position. The lower ends of the two first lifting links 9 are rotatably connected between the two grooves of the corresponding base 1 via a first pin. The upper end of each first lifting link 9 is rotatably connected to a second lifting link 12 via a second pin. The upper ends of the two second lifting links 12 directly above each base 1 are rotatably connected via a third pin. A vertical support column 13 is welded to the middle of the third pin. The two support columns 13 are slidably connected to a support block 15. In this embodiment, a support spring 14 is connected between the two first lifting links 9 or second lifting links 12 on the same side. The support spring 14 not only connects the two first lifting links 9 or second lifting links 12, but also provides a certain buffering effect, facilitating the user to take appropriate protective actions to reduce injuries caused by accidents.
[0049] Two support blocks 15 are mounted on the support column 13 of the lifting assembly. Each support block 15 is arc-shaped. In this embodiment, a first chute 16 is formed at the bottom of each support block 15. The support column 13 is slidably connected to the first chute 16, which helps maintain the stability of the support block 15 during sliding.
[0050] Two limiting grooves 17 are respectively opened on the upper surface of the corresponding support block 15 , and the limiting grooves 17 pass through the left and right sides of the corresponding support block 15 .
[0051] The limiting plate 18 is arc-shaped and slidably connected to at least one limiting slot 17. The limiting plate 18 is flush with the upper surface of the limiting slot 17. When the limiting plate 18 slides into the corresponding limiting slot 17, it can make the limiting plate 18 and the upper surface of the support block 15 aligned, making it easier for the user to sit or stand. In this embodiment, a handle 19 is welded to the middle of the upper surface of the limiting plate 18. The upper surface of the handle 19 is embedded with a control button 20 that is electrically connected to the four electric telescopic rods 5. The control button 20 can control the simultaneous extension or retraction of the four electric telescopic rods 5.
[0052] In this embodiment, the limit plate 18 and the two limit grooves 17 are on the same circular ring, the arc length of each support block 15 is less than one-quarter of the circumference of the circular ring, and the arc length of the limit plate 18 is not less than three-quarters of the circumference of the circular ring where the limit plate 18 is located, so that the limit plate 18 can still slide in at least one limit groove 17 after the support block 15 moves.
[0053] The working process of this embodiment is as follows:
[0054] The initial state of the device is: the lifting assembly is at the lowest height, the limit plate 18 is embedded in the limit groove 17 of the support block 15, and the upper surfaces of the two are flush to form a complete plane, providing a stable platform for the user to sit or hold.
[0055] During use, the width between the two support blocks 15 is adjusted according to the user's body shape. To adjust the width, the user can enter through the gap between the two bases 1. If the entry side is blocked by the connecting rod 4, the user can move the connecting rod 4 to the other side. The user then pushes the two support blocks 15 outward to increase the distance between the two support blocks 15 on the side where the user is standing. This allows for adjustable width between the two support blocks 15, making it easier for users of different body shapes to use.
[0056] After the user enters the area between the two support blocks 15, the user uses the handle 19 to slide the limit plate 18 between the two support blocks 15 in the user's forward direction. The limit plate 18 and the two support blocks 15 form a semi-enclosed area, maintaining the closure of the user's forward direction to assist the user in walking. At this point, the user activates the electric telescopic rod 5 using the control button 20, which pushes the push rod 7 to move horizontally. The push rod 7 drives the first lifting link 9 to rotate around the first pin. The first lifting link 9 drives the second lifting link 12 to rotate synchronously via the second pin, thereby converting the horizontal displacement into vertical lifting of the support column 13, thereby driving the support block 15 and the limit plate 18 to be smoothly lifted to the target height. In this process, short-distance horizontal drive achieves long-distance vertical adjustment, adapting to the needs of users of different heights.
[0057] When using this device for assisted walking, the user can grasp the handle 19 on the limit plate 18 or hold onto the two support blocks 15 to push the device. The universal wheels 2 steer flexibly, enabling free walking. When the user needs to sit or rest, they first rotate the first lifting link 9 to a predetermined position using the control button 20. This causes the fixed rod 10 to rotate and contact the rubber block 11 with the ground, thereby maintaining the relative position of the device with the help of the multiple rubber blocks 11. The user then slides the limit plate 18 out of the limit slot 17 of one support block 15, adjusts it to the appropriate position, and reinserts it into the limit slot 17 on the other side or the same side, providing the user with a wider seating platform on which to sit. The user's weight increases the friction between the rubber block 11 and the ground, further enhancing the stability and reliability of the device. Since this device does not require a separate seat or cushion, it increases the user's walking space and improves walking safety.
[0058] The above are only embodiments of the present invention, and common knowledge such as the specific structure and / or characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
