[0035] The walking aids on the market take up a large area. For the convenience of carrying and storing, the existing walking aids are designed in a foldable style. However, usually, a seat retraction hand strap is connected to the seat cushion, and one end of the hand strap is connected to a switch. When the walking aid needs to be folded, the upper body of the seat cushion is triggered by pulling the hand strap to activate the switch, causing the seat cushion to gradually fold in half, and the two side frames approach each other as the seat cushion folds in half. This method can only be operated by ordinary people or users accompanied by caregivers. For independent elderly people, their legs are already inflexible, and they still need to bend their upper bodies to the seat cushion to store the walking aid, which is difficult to operate. Moreover, the above method can only store the walking vehicle in one direction, and the stored size does not meet the requirements of users for carrying and storing.

[0036] In view of this, the present application provides a storage method for a walking aid and a walking aid. Please refer to Figure 1 and Figure 4 , the walking aid 100 includes relatively arranged main frame rods 110, two sets of front and rear wheels 150, two storage components 200, and a main rod connection component 160 provided between the two main frame rods 110;

[0037] When folding, first, through the storage component, the front and rear wheels are lifted upward and close to the main frame rod for folding; then, through the main rod connection component, the relatively arranged main frame rods approach each other for folding; finally, the front and rear wheels are flush with or higher than the bottom end of the main rod, and the folding is completed.

[0038] Figures 1 to 4 FIG. 14 is a schematic structural diagram of the walking aid provided by an embodiment of the present application. A set of front and rear wheels 150 are respectively provided on the relatively arranged main frame rods 110 on both sides. A storage component 200 is provided on each main frame rod 110, and a main rod connection component 160 is provided between the two main frame rods 110. The storage component 200 is used to store the wheels of the walking aid 100, so that the storage size and storage effect of the walking aid 100 are smaller and more convenient to carry compared with the existing walking aid 100. The main rod connection component 160 is used to make the two relatively arranged main frame rods 110 approach or move away from each other.

[0039] Figures 2 to 4 For Figure 1 the structure diagram of the walking aid 100 in Figure 5 after hiding the seat cushion in Figure 2 , Figure 3 and Figure 4 respectively show the states of the walking aid 100 when it is unfolded and used, during storage, and after storage. As shown in Figures 2 to 4As shown, when the user needs to store the walking aid device 100, since the storage assembly 200 can move relative to the main frame rod 110, the storage assembly 200 lifts the front and rear wheels 150 and folds them within the length range of the main rod. At the same time, the main rod connecting rod moves the two main frame rods 110 closer to each other until the folding is completed. This enables the walking aid device 100 to be folded and stored in the three-dimensional coordinate axes as shown in Figure 2 while folding and storing in the Y-axis (height), X-axis (width), and Z-axis (length) directions simultaneously.

[0040] Furthermore, during folding, one end of the storage assembly slides along the main frame rod, driving the front and rear wheels to rotate upward and approach the main frame rod.

[0041] One end of the storage assembly 200 and the main rod connection assembly 160 is connected to the two side main frame rods 110. During folding, the end connected to the main frame rod 110 of the storage assembly 200 slides on the main frame rod 110, causing the two main frame rods 110 to approach each other and the front and rear wheels 150 on both sides of each main frame rod 110 to approach each other and lift up.

[0042] Specifically, one end of the storage assembly 200 and the main rod connection assembly 160 is usually locked and connected to the two side main frame rods 110 through a locking structure, aiming to maintain the unfolded state when the walking aid device 100 is unfolded; the locking switch enables the storage assembly 200 and the main rod connection assembly 160 to move relative to the main frame rod 110 in the unlocked state.

[0043] On the other hand, this application also provides a walking aid device 100, which is applied to the storage method of any one of the above-mentioned walking aid devices 100. Please continue to refer to Figures 1 to 4 , the walking aid device 100 includes oppositely arranged main frame rods 110, two sets of front and rear wheels 150, two storage assemblies 200, and a main rod connection assembly 160 arranged between the two main frame rods 110. One end of the storage assembly 200 is movably connected to the first connection point of the main frame rod 110, and the other end is movably connected to the second connection point of the main frame rod 110; the front and rear wheels 150 are connected to the storage assembly 200.

[0044] The number of the main frame rods 110 corresponds to the number of the storage assemblies 200. The storage assemblies 200 are respectively connected to the first connection point and the second connection point of the main frame rod 110, so that the storage assembly 200 can move relative to the main frame rod 110 during folding, and further cause the front and rear wheels 150 to rotate upward.

[0045] In the embodiment of this application, the storage assembly 200 includes a connecting rod group 210 and a rotating rod group 220. One end of the connecting rod group 210 is connected to the front and rear wheels 150, and the other end is movably connected to the first connection point of the main rod; one end of the rotating rod group 220 is connected to the front and rear wheels 150, and the other end is movably connected to the second connection point of the main rod; the first connection point is located above the second connection point.

[0046] Since the connecting rod group 210 is used to enable the front and rear wheels 150 to approach the main frame rod 110 towards each other during folding, and the rotating rod group 220 is used to enable the front and rear wheels 150 to rotate upwards during folding until they are parallel to the bottom end of the main frame rod 110 or higher than the main frame rod 110; therefore, the connecting rod group 210 is connected to the first connection point on the main frame rod 110, and the first connection point is higher than the second connection point between the rotating rod group 220 and the main frame rod 110.

[0047] Specifically, the walking aid device 100 further includes a first sliding seat 130 disposed at the first connection point and a second sliding seat 140 disposed at the second connection point respectively; one end of the connecting rod group 210 is connected to the main frame rod 110 through the first sliding seat 130; one end of the rotating rod group 220 is connected to the main frame rod 110 through the second sliding seat 140.

[0048] In the embodiment of the present application, as Figures 2 to 4 shown, a first sliding seat 130 and a second sliding seat 140 are respectively sleeved on the main frame rod 110, where the first sliding seat 130 corresponds to the first connection point on the above-mentioned main rod, and the second sliding seat 140 corresponds to the second connection point. There are many ways for the storage assembly 200 to be movably connected to the main frame rod 110, as long as the connecting rod group 210 and the rotating rod group 220 are respectively connected to two places on the main frame rod 110, which is not limited herein.

[0049] In the embodiment of the present application, the first sliding seat 130 and the second sliding seat 140 are sleeved on the main frame rod 110, and the sliding seat can slide on the main frame rod 110, approaching or moving away from the second sliding seat 140; the second sliding seat 140 is fixedly provided at the bottom end of the main frame rod 110.

[0050] The rotating rod group 220 and the connecting rod group 210 cooperate and link with each other by approaching or moving away from each other through the first sliding seat 130 and the second sliding seat 140 that can slide on the main rod, so that the walking aid device 100 can be stored in multiple directions simultaneously.

[0051] When the walking aid device 100 is folded, it can be through the first sliding seat 130 sliding along the main frame rod 110, and the second sliding seat 140 is fixedly connected to the main frame rod 110, so that the connecting rod group 210 and the rotating rod group 220 move accordingly; it can also be through the second sliding seat 140 sliding along the main frame rod 110, and the first sliding seat 130 is fixedly connected to the main frame rod 110, or the first sliding seat 130 and the second sliding seat 140 approach or move away from each other on the main rod.

[0052] For the first embodiment provided by the present application, please refer to Figure 1 and Figure 4, the first sliding seat 130 is arranged on the main frame rod 110, and the second sliding seat 140 is fixedly arranged at the end of the main frame rod 110, that is, the end far from the handle 120. When folding, the first sliding seat 130 slides upward along the Figure 3 direction indicated by the arrow in Figure 3 . The connecting rod group 210 also moves upward as the first sliding seat 130 slides upward, and moves closer to the main frame rod 110 along the Figure 3 direction indicated by the arrow in

[0053] . The rotating rod group 220 flips upward along the Figure 5 and Figure 6 direction indicated by the arrow in Figure 5 as it moves upward with the connecting rod group 210 and approaches the main frame rod 110, thereby driving the front and rear wheels 150 to lift upward. Figure 5 and Figure 6 For the second embodiment provided by the present application, please refer to Figure 4 as shown.

[0054] In the second embodiment, the second sliding seat 140 can also be movably connected to the main frame rod 110 in the same way as the first sliding seat 130, that is, when the walking aid device 100 is stored, the second sliding seat 140 and the first sliding seat 130 move closer to each other in the same direction or away from each other in the opposite direction. At this time, the main frame rod 110 is a telescopic rod with adjustable length. Considering the relationship between the sliding range of the second sliding seat 140 on the main frame rod 110 and the maximum movable amount of each linkage component in the walking aid device 100, under the condition of restricting the length dimension of the main frame rod 110, the main frame rod 110 is used as a telescopic rod to allow the second sliding seat 140 to have a certain margin to slide on the main frame rod 110. Since the length of the main frame rod 110 and the distance between the two main frame rods 110 initially limit the size of the walking aid device 100 when it is unfolded and stored, in order to ensure that the size of the walking aid device 100 after storage can be adjusted from multiple directions, when the second sliding seat 140 is set to be movably connected to the main frame rod 110, the second sliding seat 140 is located on the telescopic rod inside the main frame rod 110.

[0055] The present application also provides a third embodiment. Please refer to Figure 7 and Figure 8 , Figure 7 and Figure 8 are schematic structural diagrams of the walking aid device 100 provided in the third embodiment of the present application. As shown in Figure 7 and Figure 8 , in the third embodiment of the present application, only one sliding seat and a connecting rod group 210 are provided on the main frame rod 110. The connecting rod group 210 is connected to the second connection part of the main frame rod 110 through an auxiliary rod 224. A chute 226 is provided on the side of the main frame rod 110 facing the main rod connection component 160. The auxiliary rod 224 can move in the chute 226. The main rod connection component 160 and the storage component 200 are connected to the sliding seat. The connecting rod group 210 moves upward as the sliding seat slides upward, driving the front wheel 161 and the rear wheel 162 connected to it to move upward.

[0056] In the embodiments of the present application, since the second sliding seat 140 is not provided and the second sliding seat 140 is arranged at the bottom end of the main frame rod 110, and the connecting rod group 210 is respectively connected to the front wheel 161 and the rear wheel 162 of the walking aid device 100. In this way, when the walking aid device 100 is in the unfolded state, to prevent the walking aid device 100 from being unstable and shaking, or during the storage process of the walking aid device 100, since the storage assembly 200 is disengaged from the main frame rod 110 and cannot continue to support the user, the user will stand unsteadily during the storage process of the walking aid device 100. Therefore, an auxiliary rod 224 is provided. The auxiliary rod 224 plays an auxiliary supporting effect when the walking aid device 100 is unfolded, further enhancing the structural stability. Since the front connecting rod 211 and the rear connecting rod 212 are connected to the auxiliary rod 224, and the auxiliary rod 224 can move in the chute 226. When the walking aid device 100 is stored, the front connecting rod 211 and the rear connecting rod 212 move upward on the sliding seat, and the auxiliary rod 224 moves and folds within the range of the chute 226, as Figure 8 shown in a "V" shape.

[0057] Please return to Figures 1 to 4 , in the first embodiment of the present application, the connecting rod group 210 includes a front connecting rod 211 and a rear connecting rod 212. The front and rear wheels 150 include a front wheel 161 and a rear wheel 162. The front connecting rod 211 is connected to the first sliding seat 130 and the front wheel 161, and the rear connecting rod 212 is connected to the first sliding seat 130 and the rear wheel 162; the rotating rod group 220 includes a front rotating rod 221 and a rear rotating rod 222. The front connecting rod 211 is connected to the second sliding seat 140 and the front wheel 161, and the rear connecting rod 212 is connected to the second sliding rod seat and the rear wheel 162; the front connecting rod 211 is hinged to the front rotating rod 221, and the rear connecting rod 212 and the rear connecting rod 212 are hinged.

[0058] When the walking aid device 100 is folded, the first sliding seat 130 slides in a direction away from the second sliding seat 140. The front connecting rod 211 and the rear connecting rod 212 move upward as the first sliding seat 130 slides upward, and move along the Figure 3 arrow direction in Figure 2 to drive the front wheel 161 and the rear wheel 162 on the same side to also move upward and approach each other, realizing the storage of the walking aid device 100 in the

[0059] X and Y directions in Figure 3 . When the first sliding seat 130 slides in a direction 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 along theFigure 2 The storage dimension in the Y direction. At the same time, since the corresponding front rotating rod 221 and rear rotating rod 222 of the front wheel 161 and rear wheel 162 are close to each other, the front wheel 161 and rear wheel 162 will also be close to each other, reducing the storage dimension of the walking aid device 100 in Figure 2 the X direction.

[0060] In this embodiment, by arranging the first sliding seat 130 and the second sliding seat 140 on the main frame rod 110 of the frame, connecting the front connecting rod 211 and the rear connecting rod 212 to the first sliding seat 130, connecting the front rotating rod 221 and the rear rotating rod 222 to the second sliding seat 140, connecting the front connecting rod 211 and the front rotating rod 221, and connecting the rear connecting rod 212 and the rear rotating rod 222, the front wheel 161 and the rear wheel 162 of the walking aid device 100 can adjust their dimensions in Figure 2 the X and Y directions during storage. Combining the above-mentioned main rod connection assembly 160 to adjust the dimensions of the two side frame main rods 110 in the length direction, that is, Figure 2 in the Z direction during storage. Only by pressing and pushing the handle 120 can the three-way storage of the walking aid device 100 be realized. The operation is simple, the practicability is strong, and the storage effect and storage dimension are more convenient for storage and carrying compared with the prior art.

[0061] It should be noted that the "front wheel" and "rear wheel" mentioned in the embodiments of the present application are only for better describing the wheels distributed on both sides of the walking aid device and for better describing the connection relationship between the above-mentioned "front and rear wheels" and the storage assembly 200 respectively, and do not limit the position and function of the wheels.

[0062] Specifically, the front connecting rod and the rear connecting rod are oppositely arranged on the main frame rod; the front rotating rod and the rear rotating rod are oppositely arranged on the frame; the distances from the front connecting rod and the rear connecting rod to the main frame rod are equal; the distances from the front rotating rod and the rear rotating rod to the main frame rod are equal.

[0063] The front connecting rod 211 and the rear connecting rod 212 are oppositely arranged and have equal distances from the main frame rod 110, being symmetrical to each other; the front rotating rod 221 and the rear rotating rod 222 are oppositely arranged, and the distances from the two to the main frame rod 110 are opposite, being symmetrical figures to each other, so that multiple triangles are formed between the main frame rod 110 and the front connecting rod 211, the rear connecting rod 212, the front rotating rod 221, and the rear rotating rod 222. The multiple triangular structures enable the structure to be more stable when the walking aid device 100 is unfolded for use by the user. During the movement of the walking aid device 100, due to multiple three-point fixed supports, the mechanical structure of the walking aid device 100 will not change during driving, accurately controlling the movement of the walking aid device 100 and enhancing the reliability of the walking aid device 100.

[0064] More specifically, the main rod connection assembly 160 includes two intersecting support rods 171, one end of each support rod 171 is movably connected to the second sliding seat 140, and the other end is movably connected to the sliding seat; when the sliding seat moves away from the second sliding seat 140, the two support rods 171 rotate along the intersection point 172 and approach each other.

[0065] The main rod connecting assembly 160 is used to connect the main rods 110 of the two sides of the frame, and when the first sliding seat 130 slides up, the main rods 110 of the two sides of the frame are moved along the Figure 3 There are many ways to bring the two relative frame main rods 110 closer to each other to accommodate the walking aid 100. In the embodiment of the present application, for example, Figures 2 to 4 As shown, the main rod connection assembly 160 is two support rods 171 that are arranged in an "X" shape and cross each other. When the sliding seat slides upward, the two support rods 171 are close to each other along their intersection points. Since the "X" shape uses fewer parts than other shapes, it can save manufacturing costs and reduce the weight of the walking aid device 100, further meeting the user's need for easy carrying; and the "X" shape is more stable than other shapes when the walking aid device 100 is unfolded or stored, and the effect of achieving multi-directional synchronous folding of the walking aid device 100 is better.

[0066] Of course, the main rod connection assembly 160 of the present application can also be "W"-shaped, "V"-shaped, "Y"-shaped, "XX"-shaped or any shape that can be presented by one or more groups of support rods with at least one intersection, and is not limited here.

[0067] In the embodiment of the present application, a handle 120 and a locking switch are provided on the frame main rod 110; when the handle 120 moves to the maximum movable range toward the frame main rod 110, the locking switch is triggered to unlock, and the main rod connecting assembly 160 is unlocked from the frame main rod 110, so that the frame main rods 110 on both sides are closer to or farther away from each other.

[0068] The locking switch is used to bring the two frame main poles 110 closer to each other through the main pole connecting assembly 160 in the unlocked state, and the locking switch is also used to fix the storage assembly 200 and the main pole connecting assembly 160 to the frame main pole 110 in the locked state. In the present application, the locking switch can be any locking structure, such as a symmetrical locking structure, a step locking structure, a marble lock, a toggle switch, etc., which can cooperate with an elastic member to achieve a stable and reliable storage assembly 200 when the walking aid device 100 is in use, and a switch structure that the storage assembly 200 can be linked when the walking aid device 100 needs to be stored.

[0069] The storage assembly 200 is a linkage assembly for unfolding or storing the walking aid 100. A handle 120 is provided on the main frame bar 110. The user can adjust the distance between the handle 120 and the main frame bar 110 to accommodate users of different heights.

[0070] In an embodiment of the storage method of the walking aid device 100, after the user adjusts the handle 120 to a suitable height, the handle 120 will be fixed on the main frame rod 110. As Figures 2 to 4 shown, when folding, when the user needs to store the walking aid device 100, first press the button (not shown in the figure) on the handle 120 to release the fixation between the handle 120 and the main frame rod 110, and then press the handle 120 downward to make the handle 120 gradually approach the main frame rod 110; when the handle 120 gradually approaches the main frame rod 110 and touches the locking switch, the locking switch is triggered to unlock. At this time, the storage assembly 200 can move relative to the main frame rod 110 and drive the two side main frame rods 110 to approach each other, so that the walking aid device 100 is Figure 2 as shown in the three-dimensional coordinate axes, and is folded and stored simultaneously in the height Y, width X, and length Z directions.

[0071] Specifically, when the handle 120 can retract to the maximum retraction stroke towards the main frame rod 110, the locking switch is triggered to unlock, so that the storage assembly 200 is unlocked from the main frame rod 110, and the two side main frame rods 110 approach or move away from each other. Of course, in the embodiment of the present application, the locking switch can also be set on the retraction path of the handle 120, and the locking switch is triggered during the retraction of the handle 120. However, considering that when the handle 120 retracts to the maximum retractable position, the telescopic rod of the handle 120 completely enters the main frame rod 110. At this time, applying a pushing force to the two side handles 120 is equivalent to directly pushing the two side main frame rods 110, reducing the step of pressing the handle 120 again to store the walking aid device 100, and the user does not need to bend deeply, making the operation more convenient and fast.

[0072] In the embodiment of the present application, to trigger the walking aid device to change from the unfolded state to the folded state, even the way for the storage assembly to change from the locked connection with the main frame rod to the unlocked connection can be pulling the pull rod on the seat cushion or other ways.

[0073] The present application also considers the situation where the user needs to carry the walking aid device on a plane. Since the size of the existing walking aid device is still too large after being stored, it is impossible to carry the walking aid device on the plane, causing inconvenience to the user. According to the regulations on luggage size for international flights (here referring to American Airlines), the maximum size of the carry-on luggage is 56 cm × 36 cm × 23 cm. When designing the walking aid wheels, not only the storage range needs to meet the size requirements for taking the plane, but also the size when the walking aid device is unfolded needs to be considered to meet the use of most people.

[0074] In view of this, please return to Figures 2 to 4 , in this embodiment, the size of the walking aid device 100 when it is unfolded and used and the size after storage are also designed. For the convenience of description and understanding, taking Figure 2Taking the coordinate axes in [reference] as a reference, hereinafter, when describing, the height of the walking aid device 100 is the dimension in the Y direction, the width is the dimension in the X direction, and the length is the dimension in the Z direction. To meet the size requirements for boarding a plane when the walking aid device 100 is stored, that is, the length × width × height of the walking aid device 100 are respectively less than or equal to 36 cm × 23 cm × 56 cm.

[0075] First, in terms of the height of the walking aid device 100, to ensure that the height of the walking aid device 100 does not exceed 56 cm, as Figures 2 to 4 shown, the height of the main frame rod 110 plus the handle 120 and the wheels in the walking aid device 100 after storage needs to be less than 56 cm. Since the wheels will be flush with the end of the main frame rod 110 after being stored in the final state, the height of the main frame rod 110 is designed to be less than 56 cm. And because the handle 120 adjusts its height through a telescopic rod, one end of the telescopic rod is located inside the main frame rod 110, and the other end protrudes from the main frame rod 110 in the height direction and is connected to the handle 120. The height of the handle 120, the height that the telescopic rod protrudes from the main frame rod 110 after retraction, and the height of the main frame rod 110 are set as the overall height of the walking aid device 100 after storage, which is less than 56 cm.

[0076] Regarding the length of the walking aid device 100, that is, the distance between the two side frames is adjusted. Most of the foldable walking aid devices 100 on the market can adjust this dimension to a size that can be taken on the plane, that is, less than 36 cm, and will not be elaborated here.

[0077] Considering that the walking aid device 100 also needs to provide a seat for the user to rest, when designing the storage size of the walking aid device 100 to meet the boarding standard, the height of the seat cushion from the ground also needs to be considered. If the seat cushion is made too low, it does not meet the ergonomic and comfortable environment. In this application, the height of the seat cushion from the ground when the walking aid device 100 is opened is 50 cm, and the diameter of the reserved seat cushion support tube is 2 cm. The storage of the entire walking aid is mainly determined by the erection angle of the main rod (including all directions), the diameter of the wheels, the positions of each wheel when opened and stored, the main rod connection component 160 connecting the left and right main frame rods 110, and the height of the seat cushion.

[0078] As described above, since this application drives the movement of the main rod connection assembly 160 by the sliding of the first sliding seat 130 to be stored or unfolded, the slidable distance of the first sliding seat 130 and the length of the X-shaped support rod 171 are also designed here. The length of the X-shaped support rod 171 is set corresponding to the length of the frame main rod 110. Since the slidable distance of the first sliding seat 130 is associated with the rotation angle of the main rod connection assembly 160, that is, the X-shaped support rod 171, and since the height of the frame main rod 110 needs to be less than 56 cm, the length of the X-shaped support rod 171 also needs to be less than the length of the frame main rod 110, which is 56 cm. Otherwise, the X-shaped support rod 171 will exceed the frame main rod 110 after being stored, resulting in the overall height of the walking aid device 100 being greater than 56 cm. Considering the above problems, the length of the X-shaped support rod 171 is about 50 cm. Since the size after the X-shaped support rod 171 is unfolded limits the distance between two relatively arranged frame main rods 110, that is, the length of the walking aid device 100 when in use, and the length of the walking aid device 100 is set to be about 50 cm to adapt to most users, such as the range where one can sit on the seat and rest as shown in Figure 1 . According to the survey data, by setting this, the slidable distance of the first sliding seat 130 on the frame main rod 110 can be set. In addition, the length of the walking aid device 100 can be set according to the width of the aircraft aisle and the cabin passage, so that the walking aid device 100 can not only be carried on the plane but also be used on the plane.

[0079] Secondly, regarding the width of the walking aid device 100, it is actually the adjustment of the distance between the front wheel 161 and the rear wheel 162. Taking the outer wheel diameters of both the front wheel 161 and the rear wheel 162 being 20 cm as an example, even when the walking aid device 100 is stored to the final state and the front wheel 161 and the rear wheel 162 are in contact with each other, the width of the walking aid device 100 is 40 cm, still exceeding the size of the luggage that can be carried on the plane as stipulated internationally. Therefore, as shown in Figure 4, when the walking aid device 100 of this application is stored to the final state, the front wheel 161 and the rear wheel 162 are arranged in a staggered and overlapping manner. However, even after the front wheel 161 and the rear wheel 162 are arranged in a staggered manner, unless the front wheel 161 and the rear wheel 162 are completely stacked and overlapped, the minimum storage size of the walking aid device 100 can only be stored to 30 cm, still exceeding the size of 23 cm of the luggage that can be carried on the plane as stipulated internationally. Therefore, as shown in Figures 1 to 4 , this application also sets the diameter of the front wheel 161 to be smaller than that of the rear wheel 162. Specifically, the diameter of the front wheel 161 is 15 cm and the diameter of the rear wheel 162 is 20 cm. In this way, when the walking aid device 100 is stored to the final state, the width of the walking aid device 100 can meet the boarding requirements, that is, 23 cm.

[0080] The size of the walking aid device provided by the embodiment of this application when stored to the final state is 51cm×30.7cm×22.9cm.
