[0002] With the development of science and technology and the increasing number of people with lower limb disability, more and more users with lower limb disability use intelligent walking aids for daily life and rehabilitation. The traditional nursing method is to hire professional caregivers to provide care or conduct rehabilitation treatment at the same time, which is time-consuming and labor-intensive; and there are fewer professional caregivers. Therefore, intelligent walking aids are becoming more and more popular, and their performance and types are also constantly improving and increasing.

[0003] In the prior art, intelligent walking aids are equipped with knee pads, which provide users with a position to support themselves, and cooperate with other devices to enable users to stand or sit upright. However, existing knee pads can only be adjusted up and down and / or forward and backward, with a small adjustment range. After adjustment, the knee pads are fixed, and local adjustments cannot be made when users feel uncomfortable during use. In addition, existing knee pad components are connected by straps, which are cumbersome to operate and inconvenient for users.

[0004] In addition, during the actual use of the walking aid, the walking aid may lean forward or shake. Due to inertia, the user's knee will directly act on the inner front side of the knee pad. Although the inner front side of the knee pad in the prior art is filled with rubber, foam or sponge and other materials to play a cushioning role, it is still easy to cause a certain degree of injury to the user.

[0055] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0056] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "left end", "right end", "vertical", "horizontal", "upper", "lower" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0057] The adjustable knee brace device of the present invention comprises a knee brace assembly 1 and an adjustment assembly 2. The adjustment assembly 2 comprises an up-and-down adjustment component 21 and / or a front-and-back adjustment component 24.

[0058] The adjustment assembly further includes a buffer component 22, and the buffer component 22 is connected to the upper and lower adjustment components 21, and the upper and lower adjustment components 21 are connected to the knee pad assembly 1;

[0059] Alternatively, one end of the buffer component 22 is connected to the front-rear adjustment component 24, and the other end of the buffer component 22 is connected to the knee pad assembly 1;

[0060] Alternatively, one end of the buffer component 22 is connected to the front-rear adjustment component 24 , and the other end of the buffer component 22 is connected to the up-down adjustment component 21 , and the up-down adjustment component 21 is connected to the knee pad assembly 1 .

[0061] Embodiment 1

[0062] Reference Figures 1 to 3 The adjustable knee pad device includes a knee pad assembly 1 and an adjustment assembly 2. The adjustment assembly 2 includes an upper and lower adjustment component 21 and a buffer component 22. One end of the buffer component 22 is connected to the upper and lower adjustment component 21, and the upper and lower adjustment component 21 is connected to the knee pad assembly 1.

[0063] The buffer component 22 includes an outer sleeve 221, an inner sleeve 222, and an elastic member 223, wherein the elastic member 223 is located between the outer sleeve 221 and the inner sleeve 222. The contact surface between the knee pad assembly 1 and the knee is made of soft material, which can be foam, sponge, air cushion, rubber, etc.

[0064] With the above solution, the user adjusts the upper and lower adjustment components 21 according to his or her own height, ensures that the knee pad assembly 1 maintains a suitable height, and then closes the knee pad assembly 1. When the user suddenly leans forward, the knee pad assembly 1 contacts the knee, and the flexible material on the contact surface can play a first buffering role. Due to the inertial force, the knee continues to push the knee pad assembly 1, and the upper and lower adjustment components 21 connected to the knee pad assembly 1 act on the buffer component 22 connected thereto, and the inner sleeve 222 in the buffer component 22 moves forward in the outer sleeve 221. The elastic member 223 located between the inner sleeve 222 and the outer sleeve 221 can share the force, play a shock absorbing and buffering role, and thus protect the user's knee from secondary injury. That is, the flexible material in the knee pad assembly 1 and the elastic member 223 in the buffer component work together to play a double buffering role to prevent the user's knee from being injured.

[0065] Furthermore, the adjustment assembly 2 also includes a rotation adjustment component 23, which includes a ball bowl 231 and a ball head 232. The first end of the ball head 232 is spherical and the second end is rod-shaped. The first end of the ball head 232 cooperates with the ball bowl 231 so that the ball head 232 rotates in the ball bowl.

[0066] In this embodiment, there are two schemes for connecting the rotating adjustment component, the buffer component, and the up-and-down adjustment component:

[0067] Option 1:

[0068] like Figure 1 , 2 As shown, one end of the buffer component 22 is connected to one end of the rotation adjustment component 23 , and the other end of the rotation adjustment component 23 is connected to the up-and-down adjustment component 21 , and the up-and-down adjustment component 21 is connected to the knee pad assembly 1 .

[0069] The specific method is as follows: the first end (i.e. the left end) of the outer sleeve 221 in the buffer component 22 is closed, the first end (i.e. the left end) of the inner sleeve 222 is partially inserted into the outer sleeve 221 from the second end (i.e. the right end) of the outer sleeve, and the inner sleeve 222 can move axially in the outer sleeve 221. In order to prevent the inner sleeve 222 from moving out of the outer sleeve 221, a stopper 224 is provided at the first end (i.e. the left end) of the inner sleeve 222, and a stopper 225 is provided at the second end (i.e. the right end) of the outer sleeve 221.

[0070] The rotation adjustment component 23 is built into the inner sleeve 222, and the ball head 232 partially abuts against the second end (i.e., the right end) of the inner sleeve 222. The second end of the ball head 232 passes through the second end of the inner sleeve 222 and is connected to the up-and-down adjustment component 21, and the up-and-down adjustment component 21 is connected to the knee pad assembly 1; the ball bowl 231 is fixedly connected to the inner sleeve 222 through the positioning member 226, and the two ends of the elastic member 223 abut against the left end of the outer sleeve and the left end of the inner sleeve respectively. The elastic member 223 can be a rubber block or a spring. In this embodiment, the elastic member is preferably a spring.

[0071] In this embodiment, the positioning member 226 is preferably a positioning screw. Of course, the positioning member 226 can also be a structure that plays a positioning role, such as a fixed support, a positioning pin, a positioning shaft, etc. The stopper 224 can be integrally formed with the inner sleeve, or it can be formed separately; the stopper 225 can be integrally formed with the outer sleeve 221, or it can be formed separately. In this embodiment, it is preferred that the stopper 224 is integrally formed with the inner sleeve, and the stopper 225 is formed separately from the outer sleeve 221.

[0072] In addition, the connection positions of the buffer component and the rotation adjustment component can be interchanged, and their connection relationship can also be:

[0073] Option 2:

[0074] like Figure 3 As shown, one end of the rotation adjustment component 23 is connected to one end of the buffer component 22 , and the other end of the buffer component 22 is connected to the up-and-down adjustment component 21 , and the up-and-down adjustment component 21 is connected to the knee pad assembly 1 .

[0075] The specific method is: both ends of the outer sleeve 221 of the buffer component 22 are non-closed ends, and the right end of the ball head 232 of the rotation adjustment component 23 is matched and connected with the left end opening of the outer sleeve 221. The connection method here can be in various forms, for example: the left end opening of the outer sleeve 221 is a threaded structure, and the right end of the ball head 232 is provided with a threaded structure, which is matched with the left end thread of the outer sleeve, and then fastened by a nut; or the right end of the ball head 232 is fixed to the left end opening of the outer sleeve by welding. Of course, the two can also be fixed by other methods.

[0076] The left end of the inner sleeve 222 is inserted into the outer sleeve from the right end of the outer sleeve 221. A stopper 227 is provided on the inner sleeve 222 inserted into the outer sleeve 221. A slide groove 228 for the stopper to slide is provided on the outer sleeve 221. The stopper 227 and the corresponding slide groove 228 can be provided on one side of the inner sleeve and the outer sleeve, or on two corresponding sides. In this embodiment, it is preferred to provide two corresponding sides. The right end of the inner sleeve 222 is connected to the upper and lower adjustment component 21, and the upper and lower adjustment component 21 is connected to the knee pad assembly 1. The elastic member is placed between the left end of the outer sleeve and the left end of the inner sleeve.

[0077] The present invention adds a rotating adjustment component on the basis of achieving up and down adjustment and avoiding secondary injuries. Since the ball head in the rotating adjustment component can rotate in the ball bowl, the range of motion of the knee pad assembly can be expanded and its adjustment flexibility can be enhanced, so that the user's leg movements can be freer and more comfortable.

[0078] Embodiment 2

[0079] The adjustable knee brace device comprises a knee brace assembly 1 and an adjusting assembly 2. The adjusting assembly 2 comprises a front and rear adjusting component 24 and a buffer component 22. One end of the front and rear adjusting component 24 is connected to one end of the buffer component 22, and the other end of the buffer component 22 is connected to the knee brace assembly 1.

[0080] Compared with the first embodiment, the second embodiment is different in that: the second embodiment has no up and down adjustment component, and adds a front and back adjustment component 24, wherein the front and back adjustment component is a structure commonly used in the art that can realize front and back adjustment, and will not be described in detail here.

[0081] In this embodiment, the connection relationship between the front and rear adjustment component, the rotation adjustment component, and the buffer component has the following two modes:

[0082] The first connection relationship is:

[0083] like Figure 4 As shown, one end of the front-rear adjustment component 24 is fixedly connected to the ball bowl 231 of the rotation adjustment component 23, the ball head 232 of the rotation adjustment component 23 is connected to the left end of the outer sleeve 221 in the buffer component 22, and the right end of the inner sleeve 222 of the buffer component 22 is connected to the knee pad assembly 1; the connection relationship between the buffer component and the rotation adjustment component in this method is the same as the scheme 2 in the embodiment 1, and will not be repeated here.

[0084] The second connection relationship is:

[0085] The buffer component 22 and the rotation adjustment component 23 adopt the solution in the first embodiment. Figure 2 As shown in the connection relationship, based on this scheme, one end of the front and rear adjustment component 24 is connected to the outer sleeve 221 of the buffer component 22, the inner sleeve 221 of the buffer component 22 is fixedly connected to the ball bowl 231 of the rotation adjustment component 23, and the ball head 232 of the rotation adjustment component 23 is connected to the knee pad assembly 1; the connection relationship between the buffer component and the rotation adjustment component in this method is the same as the scheme one in the embodiment one, and will not be repeated here.

[0086] Compared with the first embodiment, the above scheme adds a front and rear adjustment component, which can realize the front and rear adjustment of the knee pad device. Similarly, due to the presence of the buffer component, secondary injuries can be avoided. By adding a rotating adjustment component, the range of motion of the knee pad assembly is expanded and its adjustment flexibility is enhanced, making the user's leg movements more free and comfortable.

[0087] Embodiment 3

[0088] See also Figure 5 The adjustable knee pad device includes a knee pad component 1 and an adjustment component 2. The adjustment component 2 includes an up and down adjustment component 21, a buffer component 22, a rotation adjustment component 23 and a front and rear adjustment component 24.

[0089] Compared with the first embodiment, the third embodiment is different in that: a front-rear adjustment component 24 is added on the basis of the first embodiment, wherein the front-rear adjustment component is a structure commonly used in the art that can realize front-rear adjustment, and will not be described in detail here.

[0090] In this embodiment, the connection relationship between the front and rear adjustment components, the rotation adjustment components, the buffer components, and the up and down adjustment components has the following two modes:

[0091] The first method is:

[0092] One end of the front-to-back adjustment component 24 is fixedly connected to the ball bowl 231 of the rotation adjustment component 23, the ball head 232 of the rotation adjustment component 23 is connected to the left end of the outer sleeve 221 in the buffer component 22, the right end of the inner sleeve 222 of the buffer component 22 is connected to the up-down adjustment component 21, and the up-down adjustment component 21 is connected to the knee pad assembly 1; the connection relationship between the buffer component and the rotation adjustment component in this method is the same as that of the scheme 2 in the first embodiment, and will not be repeated here.

[0093] The second method is:

[0094] One end of the front-rear adjustment component 24 is connected to the outer sleeve 221 of the buffer component 22, the inner sleeve 221 of the buffer component 22 is fixedly connected to the ball bowl 231 of the rotation adjustment component 23, the ball head 232 of the rotation adjustment component 23 is connected to the up-down adjustment component 21, and the up-down adjustment component 21 is connected to the knee pad assembly 1; the connection relationship between the buffer component and the rotation adjustment component in this method is the same as that in the scheme one in the first embodiment, and will not be repeated here.

[0095] Compared with the second method, the rotation adjustment component in the first method is relatively farther away from the knee pad assembly, and its adjustable range is larger, further increasing the user's leg movement space.

[0096] The technical effect of this embodiment is that the user can adjust the upper and lower adjustment components and the front and rear adjustment components according to his / her height and body weight to ensure that the knee pad assembly is kept in a suitable position. At the same time, due to the special structure of the buffer component, it works together with the flexible material in the knee pad assembly to achieve double buffering to prevent the user's knee from being injured.

[0097] Since the ball head in the rotating adjustment component can rotate in the ball bowl, the range of motion of the knee brace component can be expanded, the adjustment flexibility thereof can be enhanced, and the user's leg motions can be freer and more comfortable.

[0098] The height adjustment of the knee pad assembly can be achieved in a variety of ways, such as using a T-slot track slider, a sleeve sliding setting, or a slide groove with screws and screw holes. The present invention only uses slide grooves, sliders with screws and limit holes as examples.

[0099] See also Figure 6 The up-down adjustment component 21 includes a slide plate 211, a slider 212, and a fixing member 213. The slide plate 211 is fixedly connected to the knee pad assembly 1. The slide plate is provided with a limiting hole 214. The slider 212 is fixed to the slide plate at a position corresponding to the limiting hole through a fixing member. The slider is provided with a connection position with a buffer component or a rotation adjustment component. There are multiple limiting holes, which facilitate different users to adjust the up-down position of the slider in the slide plate according to the knee height, thereby adjusting the vertical height of the knee pad assembly. The fixing member can be a locking screw, a pin, etc.

[0100] See also Figure 7a-7c The knee pad assembly includes a first knee pad ring 11 and a second knee pad ring 12. The first knee pad ring 11 is provided with a sandwich layer, the second knee pad ring 12 is placed in the sandwich layer, a shift block 13 is provided on the second knee pad ring 12, and a window 14 for the shift block 13 to move is opened on the first knee pad ring 11.

[0101] When the shift block 13 is located at the left end of the window 14, the knee pad assembly is in an open state; when the shift block 13 is located at the right end of the window 14, the knee pad assembly is in a closed state. When the user uses it, the shift block is shifted, and the shift block drives the second knee pad ring 12 to slide to open and close the knee pad assembly.

[0102] Furthermore, in order to make the knee pad assembly close more securely, magnetic sheets can be optionally provided at the right ends of the shift block 13 and the window 14. When the shift block 13 reaches the right end of the window 14, the magnetic sheets at the right ends of the shift block and the window attract each other, thereby making the first knee pad ring 11 and the second knee pad ring 12 close more securely.

[0103] Of course, in addition to the above solution, the dial block 13 and the right end of the window 14 are connected in a detachable manner such as a buckle;

[0104] Alternatively, the end face of the window 14 is set to be a serrated surface similar to a utility knife. This setting makes it easy for the shift block to stop at any position of the window, and the second knee pad ring 12 and the first knee pad ring 11 can still fix the user's knee in cooperation.

[0105] See also Figure 8a-8b , and the aforementioned Figure 7a-7cThe difference between the knee pad assembly scheme is that the knee pad assembly 1 further includes an elastic member 15, the elastic member 15 and the second knee pad ring 12 are placed in the interlayer, the right end of the elastic member 15 is connected to the left end of the second knee pad ring 12, and the left end of the elastic member 15 is connected to the interlayer fixed end 16. When the dial block 13 is at the left end of the window, the knee pad assembly is in an open state; when the dial block 13 is at the right end of the window, the knee pad assembly is in a closed state.

[0106] Due to the presence of the elastic member, the shift block and the window need to be provided with corresponding fixing devices, for example, a magnetic sheet is provided at the right end of the shift block 13 and the window 14 for fixing. Of course, the shift block 13 and the window 14 can also be detachably connected by a buckle or the like.

[0107] When the user is in use, the shift block is pushed, and the shift block drives the second knee pad ring to slide. When the shift block reaches the right end of the window, the magnetic sheet on the shift block and the magnetic sheet on the window attract each other to lock the first knee pad ring and the second knee pad ring, and the knee is wrapped. When not in use, the shift block is pushed in the opposite direction, and the second knee pad ring automatically shrinks into the interlayer under the action of the spring, and the knee pad assembly returns to the open state.

[0108] See also Fig. 9 The knee pad assembly includes a first knee pad ring 11, two second knee pad rings 12, and two elastic members 15. The elastic member 15 and the second knee pad ring 12 are placed in the interlayer, one end of the elastic member 15 is connected to one end of the second knee pad ring 12, and the other end of the elastic member 15 is connected to the interlayer fixed end 16. When the dial block 13 is at the left end (right end) of the window, the knee pad assembly is in an open state; when the dial block 13 is at the right end (left end) of the window, the knee pad assembly is in a closed state. The figure shows the closed state.

[0109] Due to the presence of the elastic member, the shift block and the window need to be provided with corresponding fixing devices, for example, a magnetic sheet is provided at the right end (left end) of the shift block 13 and the window 14 for fixing. Of course, the shift block 13 and the window 14 can also be connected in a detachable manner such as a buckle.

[0110] When the user is in use, the shift block is moved, and the shift block drives the second knee pad ring to slide. When the shift block reaches the right end (left end) of the window, the magnetic sheet on the shift block and the magnetic sheet on the window attract each other to lock the first knee pad ring and the second knee pad ring, and the knee is wrapped. When not in use, the shift block is moved in the opposite direction, and the second knee pad ring automatically shrinks into the interlayer under the action of the spring, and the knee pad assembly returns to the open state.

[0111] In addition, the elastic member 15 may be omitted in the above solution, and the closing and opening of the knee pad assembly can also be achieved.

[0112] See also Fig.10The knee pad assembly includes a first knee pad ring 11 and a second knee pad ring 12. The right end of the first knee pad ring 11 is connected to the left end of the second knee pad ring 12. When the left end of the first knee pad ring 11 is connected to the right end of the second knee pad ring 12, the knee pad assembly is in a closed state; when the left end of the first knee pad ring 11 is disconnected from the right end of the second knee pad ring 12, the knee pad assembly is in an open state.

[0113] The right end of the first knee pad ring 11 and the left end of the second knee pad ring 12 can be connected by a rotatable connection method such as a sliding rod and a bearing.

[0114] The left end of the first knee brace ring 11 is connected to the right end of the second knee brace ring 12 in a movable connection, for example, a snap-on type, a latch type, a nested type, etc.

[0115] Of course, the knee pad assembly may also only be provided with a first knee pad ring, the shape of which matches the knee of a human body.

[0116] In order to be more ergonomic and prevent the user from being injured due to the shaking of the calf when standing, the knee pad component can have a certain inclination angle.

[0117] See also Fig.11 , a walking aid device (the figure shows only a part of the walking aid device), which uses the adjustable knee pad device in the aforementioned embodiment to fix the adjustable knee pad device to the stepping training unit 3 in the walking aid device.

[0118] Different numbers of knee pads can be set according to actual needs during use. For example, in stepping rehabilitation training, the knee pads and stepping boards are arranged symmetrically on the left and right. Since the knee pads can be adjusted at multiple angles and have a large adjustable range, when the user needs to exercise, the brake device is used to control the left and right pedals and the knee pads to make alternating movements up and down, front and back, and left and right, thereby driving the user's lower limbs to reciprocate and achieve the purpose of stepping rehabilitation training.

[0119] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians of the present invention, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
