[0058] In the embodiments of the present application, the first sliding seat 130 and the second sliding seat 140 are sleeved on the frame main rod 110, and the sliding seats can slide on the frame main rod 110 to approach or move away from the second sliding seat 140; the second sliding seat 140 is fixedly arranged at the bottom end of the frame main rod 110.

[0059] The rotating rod group 220 and the connecting rod group 210 are cooperatively linked to realize the folding of the assembly 200 by approaching or moving away from each other through the first sliding seat 130 and the second sliding seat 140 which can slide on the main rod, so that the walking aid 100 can be folded in multiple directions at the same time.

[0060] When the walking aid 100 is folded, the connecting rod group 210 and the rotating rod group 220 can be cooperatively moved by the first sliding seat 130 sliding along the frame main rod 110 and the second sliding seat 140 being fixedly connected with the frame main rod 110, or by the second sliding seat 140 sliding along the frame main rod 110 and the first sliding seat 130 being fixedly connected with the frame main rod 110, or by the first sliding seat 130 and the second sliding seat 140 approaching or moving away from each other on the main rod.

[0061] In the first embodiment provided by the present application, referring to FIG. 1 and FIG. 4, the first sliding seat 130 is arranged on the frame main rod 110, and the second sliding seat 140 is fixedly arranged at the end of the frame main rod 110 away from the handle 120; when folding, the first sliding seat 130 slides upward along the direction indicated by the arrow in FIG. 3, the connecting rod group 210 slides upward along with the first sliding seat 130 and moves upward, and approaches the frame main rod 110 along the direction indicated by the arrow in FIG. 3, and the rotating rod group 220 moves upward along with the connecting rod group 210, folds upward along the direction indicated by the arrow in FIG. 3, and approaches the frame main rod 110, thereby lifting the front and rear wheels 150 upward.

[0062] In the second embodiment provided by the present application, referring to FIG. 7 and FIG. 8, the main rod connecting assembly 160 is arranged between the two frame main rods 110, and the main rod connecting assembly 160 is connected with the two frame main rods through the connecting rod 223; when folding the walking aid 100, the second sliding seat 140 fixedly connected with the frame main rod 110 is moved downward by pressing the frame main rod 110 downward, the connecting rod 223 is gradually changed from being inclined to being parallel to the main rod, and the front rotating rod 221 and the rear rotating rod 222 are rotationally connected with the second sliding seat 140, so that the front rotating rod 221 and the rear rotating rod 222 are folded upward along the end of the second sliding seat 140 away from the main rod, the front rotating rod 221 and the rear rotating rod 222 are changed from being downwardly opened to being upwardly opened, and form a rhombus together with the front connecting rod 211 and the rear connecting rod 212, and finally the wheels are folded as shown in FIG. 4.

[0063] In the second embodiment, the second sliding seat 140 can also be movably connected with the frame main rod 110 as the first sliding seat 130, that is, the second sliding seat 140 and the first sliding seat 130 are moved towards each other or away from each other when the walker 100 is folded, at this time, the frame main rod 110 is a telescopic rod with adjustable length. Considering the sliding range of the second sliding seat 140 on the frame main rod 110 and the maximum movable amount of each linkage assembly in the walker 100, the frame main rod 110 is used as a telescopic rod to provide a certain amount of space for the second sliding seat 140 to slide on the frame main rod 110 under the condition of limiting the length of the frame main rod 110. The length of the frame main rod 110 and the distance between the two frame main rods 110 preliminarily limit the size of the walker 100 when it is unfolded and folded. In order to ensure that the size of the walker 100 after folding can be adjusted from multiple directions, when the second sliding seat 140 is movably connected with the frame main rod 110, the second sliding seat 140 is located on the telescopic rod inside the frame main rod 110.

[0064] The third embodiment of the present application is provided, please refer to FIG. 9 and FIG. 10. In the third embodiment of the present application, only one sliding seat and a connecting rod group 210 are arranged on the frame main rod 110, the connecting rod group 210 is connected with the second connecting position of the frame main rod 110 through an auxiliary rod 224, and the frame main rod 110 is provided with a sliding groove 226 on the side facing the main rod connecting assembly 160. The auxiliary rod 224 can move in the sliding groove 226. The main rod connecting assembly 160 and the folding assembly 200 are connected with the sliding seat. The connecting rod group 210 assembly moves upwards with the sliding seat, and drives the front wheel 151 and the rear wheel 152 connected therewith to move upwards.

[0065] In the third embodiment, no second sliding seat 140 is arranged, and the connecting rod group 210 is connected with the front wheel 151 and the rear wheel 152 of the walker 100. In this way, in the unfolded state of the walker 100, the walker 100 is prevented from shaking due to instability, or in the folding process of the walker 100, the folding assembly 200 cannot continue to support the user because it is disconnected from the frame main rod 110, and the user cannot stand stably during the folding process of the walker 100. Therefore, the auxiliary rod 224 is arranged, which has an auxiliary supporting effect when the walker 100 is unfolded, further enhancing the structural stability. Since the front connecting rod 211 and the rear connecting rod 212 are connected with the auxiliary rod 224, and the auxiliary rod 224 can move in the sliding groove 226, in the folding process of the walker 100, the front connecting rod 211 and the rear connecting rod 212 move upwards with the sliding seat, and the auxiliary rod 224 moves in the sliding groove 226 to fold, as shown in FIG. 8, forming a “V” shape.

[0066] Please refer to FIG. 1 to FIG. 4, in the first embodiment of the present application, the connecting rod group 210 includes front connecting rod 211 and rear connecting rod 212, the front and rear wheels 150 include front wheel 151 and rear wheel 152, the front connecting rod 211 is connected with the first sliding seat 130 and the front wheel 151, the rear connecting rod 212 is connected with the first sliding seat 130 and the rear wheel 152; the rotating rod group 220 includes front rotating rod 221 and rear rotating rod 222, the front connecting rod 211 is connected with the second sliding seat 140 and the front wheel 151, the rear connecting rod 212 is connected with the second sliding seat and the rear wheel 152; the front connecting rod 211 is connected with the front rotating rod 221, and the rear connecting rod 212 is connected with the rear rotating rod 222.

[0067] When the walking aid 100 is folded, the first sliding seat 130 slides away from the second sliding seat 140, the front connecting rod 211 and the rear connecting rod 212 move up with the first sliding seat 130, and move in the direction of the arrow in FIG. 3, so as to drive the front wheel 151 and the rear wheel 152 on the same side to move up and close to each other, so as to realize the storage of the walking aid 100 in the X and Y directions in FIG. 2.

[0068] When the first sliding seat 130 slides away from the second sliding seat 140, the front rotating rod 221 and the rear rotating rod 222 rotate upward around the second sliding seat 140 in the direction of the arrow in FIG. 3, the front rotating rod 221 and the rear rotating rod 222 close to each other, and approach the main rod 110 of the frame, so as to drive the front wheel 151 and the rear wheel 152 connected therewith to rotate in the Y direction from the original direction below the main rod 110 of the frame to the height range of the main rod 110 of the frame, so as to reduce the storage size of the walking aid 100 in the Y direction in FIG. 2. At the same time, the front wheel 151 and the rear wheel 152 will close to each other due to the close of the front rotating rod 221 and the rear rotating rod 222, so as to reduce the storage size of the walking aid 100 in the X direction in FIG. 2.

[0069] In this embodiment, by arranging the first sliding seat 130 and the second sliding seat 140 on the main rod 110 of the frame, connecting the front connecting rod 211 and the rear connecting rod 212 with the first sliding seat 130, connecting the front rotating rod 221 and the rear rotating rod 222 with the second sliding seat 140, connecting the front connecting rod 211 with the front rotating rod 221, and connecting the rear connecting rod 212 with the rear rotating rod 222, the front wheel 151 and the rear wheel 152 of the walking aid 100 are adjusted in size in the width and height directions, i.e. in the X and Y directions in FIG. 2, during storage, and the main rod connecting assembly 160 is combined to adjust the size of the two side main rods 110 of the frame in the length direction, i.e. in the Z direction in FIG. 2, during storage, so that the walking aid 100 can be stored in three directions only by pressing and pushing the handle 120, the operation is simple and convenient, the practicability is strong, and the storage effect and the storage size are more convenient for storage and carrying compared with the prior art.

[0072] That is, the front connecting rod 211 and the rear connecting rod 212 are symmetrically arranged with each other; the front rotating rod 221 and the rear rotating rod 222 are symmetrically arranged with each other. Since the front connecting rod 211 and the rear connecting rod 212 are symmetrically arranged on the main rod 110 of the frame to form a triangle, and the front rotating rod 221 and the rear rotating rod 222 are symmetrically arranged on the main rod 110 of the frame to form a triangle, a plurality of triangles are formed between the main rod 110 of the frame and the front connecting rod 211, the rear connecting rod 212, the front rotating rod 221 and the rear rotating rod 222. The plurality of triangular structures make the structure more stable when the walking aid device 100 is unfolded for use by the user, and due to the plurality of three-point fixed supports when the walking aid device 100 moves, the mechanical structure of the walking aid device 100 does not change during the driving process, the movement of the walking aid device 100 is accurately controlled, and the reliability of the walking aid device 100 is enhanced.

[0073] More specifically, the main rod connecting assembly 160 includes two intersecting support rods 151, each of which is movably connected to the second sliding seat 140 at one end and movably connected to the first sliding seat 130 at the other end; when the sliding seat moves away from the second sliding seat 140, the two support rods 151 rotate along the intersection point 152 and move closer to each other.

[0074] The main rod connecting assembly 160 is a linkage rod that connects the two side frame main rods 110 and causes the two side frame main rods 110 to move closer to or away from each other along the direction of the arrow in FIG. 3 when the first sliding seat 130 slides upward. There are many ways to bring the two opposite frame main rods 110 closer to each other to store the walking aid device 100. In the embodiments of the present application, as shown in FIGS. 2 to 4, the main rod connecting assembly 160 is two support rods 151 arranged in an "X" shape, and when the sliding seat slides upward, the two support rods 151 move closer to each other along the intersection point. Since the "X" shape uses fewer parts than other shapes in the structural design, it saves manufacturing costs while reducing the weight of the walking aid device 100, further meeting the needs of users for easy portability; and the "X" shape is more stable than other shapes in the structural design when the walking aid device 100 is unfolded or during storage, achieving a better effect of multi-directional synchronous folding of the walking aid device 100.

[0075] Of course, the main rod connecting assembly 160 of the present application can also be "W" shaped, "V" shaped, "Y" shaped, "XX" shaped or any shape that one or more groups of support rods with at least one intersection can present, which is not limited herein.

[0076] In the embodiment of the present application, the handle 120 and the locking switch are arranged on the main rod 110 of the frame; when the handle 120 is moved to the maximum movable range of the main rod 110 of the frame, the locking switch is triggered to be unlocked, and the main rod connecting assembly 160 is unlocked with the main rod 110 of the frame, so that the two main rods 110 of the frame are close to or away from each other.

[0077] The locking switch is used to make the two main rods 110 of the frame close to each other through the main rod connecting assembly 160 in the unlocked state, and is also used to fix the storage assembly 200 and the main rod connecting assembly 160 to the main rod 110 of the frame in the locked state. In the present application, the locking switch can be any lock structure, such as symmetrical lock, stepped lock, marble lock, toggle switch, etc. cooperating with elastic members, which can realize the stable and reliable storage of the storage assembly 200 when the walking aid 100 is used, and the linkage switch structure of the storage assembly 200 when the walking aid 100 needs to be stored.

[0078] The storage assembly 200 is a linkage assembly for unfolding or storing the walking aid 100. The handle 120 is arranged on the main rod 110 of the frame, and the user can adjust the distance between the handle 120 and the main rod 110 of the frame to adapt to users of different heights.

[0079] In the embodiment of the storage method of the walking aid 100, after the user adjusts the handle 120 to the appropriate height, the handle 120 is fixed on the main rod 110 of the frame. As shown in FIGS. 2 to 4, when the user needs to store the walking aid 100, the handle 120 is first fixed on the main rod 110 of the frame by pressing the button (not shown) on the handle 120, and then the handle 120 is pressed downward to gradually approach the main rod 110 of the frame; when the handle 120 gradually approaches the main rod 110 of the frame and touches the locking switch, the locking switch is triggered to be unlocked, at this time, the storage assembly 200 can move relative to the main rod 110 of the frame, and drive the two main rods 110 of the frame to approach each other, so that the walking aid 100 is folded and stored from the height Y, width X and length Z directions as shown in the three-dimensional coordinate system in FIG. 2.

[0080] Specifically, the handle 120 can trigger the locking switch to unlock when it is retracted to the maximum retraction stroke, so that the storage assembly 200 is unlocked with the main frame rod 110, and the two side main frame rods 110 are close to or away from each other. Of course, in the embodiment of the application, the locking switch can also be arranged on the retraction path of the handle 120, and the locking switch is triggered in the retraction path of the handle 120, but considering that when the handle 120 is retracted to the maximum retractable position, the telescopic rod of the handle 120 is completely entered into the main frame rod 110, at this time, the pushing force applied to the two side handles 120 is equivalent to directly pushing the two side main frame rods 110, which reduces the step of pressing the handle 120 again to store the walking aid device 100, and the user does not need to bend over deeply, and the operation is more convenient and fast.

[0081] In the embodiment of the application, the handle 120 can trigger the locking switch to unlock when it is retracted to the maximum retraction stroke, so that the storage assembly 200 is unlocked with the main frame rod 110, and the two side main frame rods 110 are close to or away from each other. Of course, in the embodiment of the application, the locking switch can also be arranged on the retraction path of the handle 120, and the locking switch is triggered in the retraction path of the handle 120, but considering that when the handle 120 is retracted to the maximum retractable position, the telescopic rod of the handle 120 is completely entered into the main frame rod 110, at this time, the pushing force applied to the two side handles 120 is equivalent to directly pushing the two side main frame rods 110, which reduces the step of pressing the handle 120 again to store the walking aid device 100, and the user does not need to bend over deeply, and the operation is more convenient and fast.

[0082] In the embodiment of the application, as shown in FIG. 5, the first sliding seat includes a first mounting portion and a first mounting port; the second sliding seat includes a second mounting portion and a second mounting port; one end of the connecting rod group is connected with the first mounting portion, and the rotating rod group is connected with the second mounting portion; and the main rod connecting assembly is connected with the first mounting port and the second mounting port respectively.

[0083] As shown in FIGS. 1-5, by arranging the first mounting portion 131 on the first sliding seat 130, which is connected with the front connecting rod 211 and the rear connecting rod 212 respectively, and the first mounting port 132, which is connected with the main rod connecting assembly 170, it should be noted that the first mounting portion 131 shown in FIG. 5 is relatively arranged in two parts, which is not shown due to the angle of view. Correspondingly, the second sliding seat 140 is provided with two second mounting portions 141, which are connected with the front rotating rod 221 and the rear rotating rod 222 respectively, and the second mounting port 142, which is connected with the main rod connecting assembly 170. Thus, the main rod connecting assembly 170, the front connecting rod 211, the rear connecting rod 212, the front rotating rod 221 and the rear rotating rod 222 are connected with each other, and by sliding the first sliding seat 130 on the main frame rod 110, the above-mentioned components can be moved at one time, so that the walking aid device 100 can be folded and unfolded along the X, Y and Z axes in FIG. 2 at the same time.

[0084] In some embodiments of the application, please refer to FIGS. 1-4, and in combination with FIG. 6, the front wheel 110 is provided with a steering mechanism 180, which includes a first connecting portion 181 and a second connecting portion 182, the front wheel connecting rod 141 is connected with the first connecting portion 181, and the front wheel rotating rod 151 is connected with the second connecting portion 182.

[0085] The front wheel 151 is provided with a steering mechanism 180, i.e., the front wheel 151 is a universal wheel, so as to improve the flexibility and maneuverability of the walking aid 100, and the walking aid 100 can adapt to various different environments and move more smoothly. Since the front connecting rod 211 and the front rotating rod 221 need to be pinned, and the front wheel connecting rod 211 is moved to drive the front wheel rotating rod 221 to rotate through the pin shaft, in the embodiment, the first connecting part 181 and the second connecting part 182 connecting the front connecting rod 211 and the front rotating rod 221 respectively are further arranged on the steering mechanism 180, so as to realize pinning of the front wheel connecting rod 211 and the front wheel rotating rod 221, and replace the structure of the fixed pin and the positioning pin.

[0086] In the embodiment, the walking aid 100 further comprises a brake cable 170, one end of the brake cable 170 is connected with the brake pad 153 on the rear wheel 152, and the other end is connected with the handle 120.

[0087] As shown in FIG. 1 and FIG. 6, the walking aid 200 further comprises a handle 220, which is used for the user to hold and support the user who cannot move to stand. The handle 220 can be telescopic in the direction of the main rod 130, i.e., the Y direction in FIG. 9, so as to adapt to the height of various users. Further, please refer to FIG. 2 and FIG. 3, when the walking aid 100 is folded to the final state, the handle 220 abuts against the first connecting seat 140.

[0088] Continuing to refer to FIG. 2 and FIG. 4, the handle 120 is connected with the brake pad 153 through the brake cable 170, and the user can also control the brake of the walking aid 100 through the handle 120, so as to ensure the safety of the user. Based on the above-mentioned embodiment that the front wheel is a universal wheel, since the load capacity of the universal wheel is relatively weak due to the guiding function, in this embodiment, the brake pad 153 is arranged on the rear wheel 152, so as to control the braking of the walking aid 200. Of course, the way that the handle 120 prevents the wheel from moving through the brake pad 153 can be any scheme that can realize this function, and the brake pad 153 and the like can also be arranged on any wheel of the walking aid 100.

[0089] The present application also takes into account the situation that the user needs to carry the walking aid to board the plane. Since the size of the existing walking aid is still too large after being stored, the user cannot carry the walking aid to board the plane, which causes inconvenience to the user. According to the luggage size regulation of international aviation (here, referring to the United States aviation), the maximum size of the luggage that can be carried to board the plane is 56 cm x 36 cm x 23 cm. When designing the walking aid wheel, not only the storable range needs to meet the size regulation of boarding the plane, but also the size of the walking aid when unfolded needs to be considered, so as to be suitable for most people to use.

[0090] In view of this, please return to FIG. 2 to FIG. 4, the size of the folding and the size of the storage of the walking aid device 100 in this embodiment are also designed. For the convenience of description and understanding, taking the coordinate axis in FIG. 2 as the reference, the height of the walking aid device 100 is taken as the size in the Y direction, the width is taken as the size in the X direction, and the length is taken as the size in the Z direction in the following description. In order to meet the requirements of the size of the walking aid device 100 when it is stored, that is, the length, width and height of the walking aid device 100 are less than or equal to 23 cm, 36 cm and 56 cm respectively.

[0091] Firstly, in the height of the walking aid device 100, in order to ensure that the height of the walking aid device 100 does not exceed 56 cm, as shown in FIG. 2 to FIG. 4, the height of the frame main rod 110 plus the handle 120 and the wheels in the walking aid device 100 needs to be less than 56 cm after storage. Since the wheels are flush with the end of the frame main rod 110 after being stored to the final state, the height of the frame main rod 110 is designed to be less than 56 cm. Since the handle 120 is adjusted in height by the telescopic rod, one end of the telescopic rod is located in the frame main rod 110, and the other end protrudes out of the frame main rod 110 in the height direction and is connected with the handle 120. The height of the handle 120, the height of the telescopic rod after retraction and protruding out of the frame main rod 110 and the height of the frame main rod 110 are set as the overall height of the walking aid device 100 after storage, which is less than 56 cm.

[0092] In addition, the walking aid 100 also needs to provide a seat for the user to rest. In order to meet the requirements of the aircraft, the size of the walking aid 100 needs to be designed to be small enough. In addition, the height of the seat cushion from the ground also needs to be considered. If the seat cushion is too low, it will not be comfortable for the user. The height of the seat cushion from the ground is 50 cm when the walking aid 100 is opened, and the diameter of the seat cushion support tube is 2 cm. The size of the walking aid 100 is mainly determined by the angle of the main rod (including all directions), the diameter of the wheels, the position of the wheels when they are opened and stored, the main rod connecting assembly 160 connecting the left and right frame main rods 110, and the height of the seat cushion. As mentioned above, the first sliding seat 130 slides to drive the main rod connecting assembly 160 to move to store or unfold. The sliding distance of the first sliding seat 130 and the length of the X-shaped support rod 151 are also designed. The sliding distance of the first sliding seat 130 is related to the rotation angle of the X-shaped support rod 151 of the main rod connecting assembly 160. Since the height of the frame main rod 110 needs to be less than 56 cm, the length of the X-shaped support rod 151 also needs to be less than the length of the frame main rod 110, i.e. 56 cm. Otherwise, the X-shaped support rod 151 will exceed the frame main rod 110 when it is stored, which will result in the overall height of the walking aid 100 being greater than 56 cm. Considering the above problem, the length of the X-shaped support rod 151 is about 50 cm. Since the size of the unfolded X-shaped support rod 151 limits the distance between the two oppositely arranged frame main rods 110, i.e. the length of the walking aid 100 when it is in use, the length of the walking aid 100 is set to be about 50 cm to accommodate most users who can sit on the seat cushion to rest as shown in FIG. 1. According to the survey data, the length of the walking aid 100 when it is unfolded is set to be about 50 cm, and the sliding distance of the first sliding seat 130 on the frame main rod 110 is also set accordingly. In addition, the length of the walking aid 100 can be set according to the width of the aircraft aisle or cabin passage, so that the walking aid 100 can not only be carried on the aircraft, but also be used on the aircraft.

[0093] Secondly, the width of the walking aid 100 is actually the adjustment of the distance between the front wheel 151 and the rear wheel 152. Taking the outer diameter of the front wheel 151 and the rear wheel 152 as an example, both of which are 20 cm, even if the front wheel 151 and the rear wheel 152 are in contact when the walking aid 100 is stored to the final state, the width of the walking aid 100 is 40 cm, which still exceeds the international standard size of luggage that can be carried on the aircraft. Therefore, as shown in FIG. 4, the walking aid 100 of the present application is arranged in a staggered and overlapping manner when it is stored to the final state, and the diameter of the front wheel 151 is set to be smaller than the diameter of the rear wheel 152. Specifically, the diameter of the front wheel 151 is 15 cm, and the diameter of the rear wheel 152 is 20 cm. In this way, the width of the walking aid 100 when it is stored to the final state can meet the requirements of the aircraft, i.e. less than 36 cm.

[0094] The length of the walking aid 100, i.e. the distance between the two frame main rods 110, can be adjusted to a size less than 23 cm in most of the folding walking aids 100 on the market, which will not be described here. It should be noted that the length of the walking aid 100 after folding should take into account the effect of the staggered overlap of the front wheel 151 and the rear wheel 152 on the length of the walking aid 100.

[0095] The size of the walking aid 100 after folding to the final state is 51 cm x 30.7 cm x 22.9 cm.

[0096] For the embodiments of the present application, it should also be noted that the embodiments of the present application and the features in the embodiments can be combined with each other to obtain new embodiments without conflict.
