Description

Technical Field

[0001] This application relates to the field of exoskeleton technology, and in particular to a leg support structure and exoskeleton device. Background Technology

[0002] Existing exoskeleton products often feature fixed structures in the legs that come into contact with the body, such as leg supports. These existing leg support structures combine rigid leg braces with flexible padding to provide better support and a comfortable wearing experience. However, the size of the leg support may need to be adjusted to accommodate different leg shapes and circumferences. For example, size adjustment is achieved by sewing adjustable leg straps into the padding. Since the dimensions of the human thigh can vary greatly, adjusting the leg support size via the leg straps can cause the padding to be stretched and deformed, affecting the fit between the padding and the thigh, and ultimately impacting the user's wearing experience.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships, for example, A and / or B can represent: A alone, A and B at the same time, and B alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0032] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0033] This application provides an exoskeleton device. Figure 1 This is a schematic diagram of the structure of the exoskeleton device provided in the embodiments of this application; Figure 2 for Figure 1 A structural diagram of the exoskeleton device from another angle. (See diagram below.) Figure 1 and Figure 2 As shown, the exoskeleton device includes a leg support structure 100 and a leg frame 200, wherein the leg support structure 100 is fixed to the leg frame 200.

[0034] It is understood that the exoskeleton device includes at least one leg support structure 100; or, the exoskeleton device includes two leg support structures 100. At least one leg support structure 100 is the leg support structure 100 described in the following technical solution. Of course, the exoskeleton device may also include a calf support structure for wearing on the outside of the user's lower leg, which will not be elaborated further.

[0035] Figure 3 for Figure 2 An enlarged diagram of point A in the middle; as shown Figure 3 As shown in the figure, this application embodiment provides a leg support structure 100. The leg support structure 100 includes a first leg support 110 and a second leg support 120 forming a ring structure. The first leg support 110 includes a support frame 111 and a flexible binding member 112. The flexible binding member 112 is disposed on the inner side of the support frame 111 facing the second leg support 120, for contacting the human leg. The leg support structure 100 can be installed on the leg frame 200 of an exoskeleton device. The first leg support 110 and the second leg support 120 are used to surround the outer side of the human leg, that is, the human leg can be placed within the ring structure formed by the first leg support 110 and the second leg support 120. The first leg support 110 can be used for the front side of the human leg, and the second leg support 120 can be used for the rear side of the human leg. The support frame 111 in the first leg support 110 provides support, and the flexible binding member 112 is disposed on the inner wall of the support frame 111 to contact the human leg, providing better support and wearing experience for the user.

[0036] like Figure 3 As shown, one end of the flexible binding member 112 is fixed relative to the support frame 111, and the other end of the flexible binding member 112 is fixed to the support frame 111 in an adjustable manner through the adjustment component 113; the adjustment component 113 is also connected between the first leg support 110 and the second leg support 120, and is used to adjust the circumferential dimension of the annular structure.

[0037] It is worth noting that in the leg support structure 100, one end of the flexible binding member 112 is fixed to the support frame 111, and the other end is also fixed to the support frame 111. Specifically, an adjustment component 113 is provided between the other end of the flexible binding member 112 and the support frame 111. When the first leg support 110 and the second leg support 120 adjust the circumferential dimension of the annular structure through the adjustment component 113, the adjustment component 113 can simultaneously adjust the posture of the flexible binding member 112, so that the distance between the other end of the flexible binding member 112 and the side of the second leg support 120 connected to the adjustment component 113, and the change in the circumferential dimension of the annular structure achieved by the adjustment component 113 are positively correlated, ensuring that the flexible binding member 112 can always adapt to the shape of the human leg in a better posture.

[0038] For example, when the size of the ring structure increases, the distance between the other end of the flexible binding member 112 and one side of the second leg support 120 connected to the adjustment assembly 113 also increases; when the size of the ring structure decreases, the distance between the other end of the flexible binding member 112 and one side of the second leg support 120 connected to the adjustment assembly 113 also decreases.

[0039] It should be noted that the leg support structure 100 provided in this application embodiment, by setting an adjustment component 113 in the annular structure, can precisely drive the first leg support 110 and the second leg support 120 to generate relative displacement, thereby flexibly changing the distance between them and realizing the dynamic adjustment of the overall size of the annular structure to adapt to users with different thigh dimensions. At the same time, the flexible binding member 112 in the leg support structure 100 is connected to the support frame 111 through the adjustment component 113, so that while the size of the first leg support 110 and the second leg support 120 is adjusted, its own posture is adjusted to ensure that the flexible binding member 112 can always adapt to the shape of the human leg in a better posture, ensuring the fit between the flexible binding member 112 and the thigh, and improving the user's wearing comfort and wearing experience.

[0040] Therefore, the leg support structure 100 can simultaneously adjust its own size and adjust the fit of the flexible binding member 112 to improve the user's wearing experience.

[0041] Figure 4 This is a partial cross-sectional view of the leg support structure 100 provided in an embodiment of this application. Please refer to... Figure 3 refer to Figure 4As shown in the structure, in some embodiments, the adjustment component 113 provided in this application includes an adjustment belt 1131 and an adjuster 1132. The adjuster 1132 can be used to fix the position of the leg frame 200 in the exoskeleton device. The support frame 111 is slidably connected to the adjuster 1132, and the second leg support 120 is connected to the adjuster 1132. The adjustment belt 1131 has a first end and a second end. The first end is connected to the flexible binding member 112, and the second end follows the support frame 111. The portion of the adjustment belt 1131 located between the first end and the second end is wound around at least part of the adjuster 1132. The adjuster 1132 is used to set the winding path of the adjustment belt 1131, such that the length of the adjustment belt 1131 between the adjuster 1132 and the flexible binding member 112 is positively correlated with the length of the support frame 111 sliding out from the adjuster 1132.

[0042] In the sliding structure between the support frame 111 and the adjuster 1132, since the adjuster 1132 is fixed relative to the leg support 200, the adjuster 1132 serves as the fixed end, and the support frame 111 serves as the movable end. It should be understood that one end of the support frame 111 is connected to one end of the second leg support 120, and the other end of the support frame 111 is connected to the adjuster 1132. The other end of the second leg support 120 is also connected to the adjuster 1132. The dimensional adjustment of the annular structure is specifically achieved through the sliding of the support frame 111 relative to the adjuster 1132.

[0043] Figure 5 for Figure 4 A simplified schematic diagram illustrating the use of the middle leg support structure 100. (See attached diagram.) Figure 5 As shown, in the initial state, the support frame 111 does not slide relative to the adjuster 1132. At this time, the dimension between the end of the support frame 111 facing the second leg support 120 and the second leg support 120 is small, and the length of the adjusting strap 1131 between the adjuster 1132 and the flexible binding member 112 is also short.

[0044] Figure 6 for Figure 4 A simplified schematic diagram of another use of the middle leg support structure 100. (See attached diagram.) Figure 6 and Figure 4 As shown, when a user needs to increase their leg circumference, along... Figure 4 and Figure 5 The center pulls the support frame 111, causing the self-adjusting device 1132 of the support frame 111 to extend further. During this process, the length of the adjusting strap 1131 between the adjuster 1132 and the flexible binding member 112 increases synchronously, allowing the flexible binding member 112 to adjust its position and shift, thus adapting to the shape of the thigh circumference in a better posture, ensuring the fit between the flexible binding member 112 and the thigh, and improving the user's wearing comfort and experience.

[0045] It is worth noting that, such as Figure 6 The dimension between the end of the support frame 111 near the second leg support 120 and the second leg support 120 is compared to Figure 5 As the size of the device increases, the length of the adjustment strap 1131 between the adjuster 1132 and the flexible binding member 112 also increases, so as to facilitate the position and posture adjustment of the flexible binding member 112.

[0046] Conversely, when users need to compare with Figure 6 The structure in the middle reduces the leg circumference to Figure 5 When the structure is shown, along Figure 6 Pushing the support frame 111 towards b reduces the length of the self-adjusting device 1132 that extends from the support frame 111. During this process, the length of the adjusting strap 1131 between the adjuster 1132 and the flexible binding member 112 decreases simultaneously, allowing the flexible binding member 112 to adjust its position and shift, thus better adapting to the shape of the calf circumference, ensuring a good fit between the flexible binding member 112 and the thigh, and improving the user's wearing comfort and experience.

[0047] In some embodiments, such as Figure 4 As shown, the adjuster 1132 has a sliding groove 1132-1, the sliding groove 1132-1 has a first opening 1132-2 and a second opening 1132-3 that are disposed opposite to each other, at least a portion of the support frame 111 extends into the sliding groove 1132-1 through the first opening 1132-2 and slides in cooperation with the sliding groove 1132-1; at least a portion of the adjusting belt 1131 is inserted into the sliding groove 1132-1 through the second opening 1132-3.

[0048] like Figure 4 As shown, the regulator 1132 is also provided with a through hole 1132-4, which is located between the first opening 1132-2 and the second opening 1132-3 and communicates with the sliding groove 1132-1; a portion of the adjusting band 1131 passes through the through hole 1132-4 to the outside of the sliding groove 1132-1, and the second end of the adjusting band 1131 enters the sliding groove 1132-1 from the first opening 1132-2 and is fixed to a portion of the support frame 111 located in the sliding groove 1132-1.

[0049] In this embodiment, the adjuster 1132 is used to define the winding path of the adjusting tape 1131. Specifically, as shown... Figure 4As shown, the through hole 1132-4 is used to switch the adjustment belt 1131 inside and outside the sliding groove 1132-1, so that the adjustment belt 1131 can switch the different parts of itself in the direction of movement, control the part of the adjustment belt 1131 connected to the flexible binding member 112 to move in the same direction as the support frame 111, and ensure that the length of the adjustment belt 1131 between the adjuster 1132 and the flexible binding member 112 is positively correlated with the length of the support frame 111 sliding out from the adjuster 1132.

[0050] Figure 7 This is a partial cross-sectional schematic view of the leg support structure 100 provided in an embodiment of this application. Exemplarily, it is now shown below. Figure 7 The adjustment band 1131 shown is divided into three segments according to its position: a first segment 1131-1, a second segment 1131-2, and a third segment 1131-3. The first segment 1131-1 is located outside the sliding groove 1132-1 and between the flexible binding member 112 and the second opening 1132-3. The second segment 1131-2 is partially located inside and partially outside the sliding groove 1132-1, and is located between the first opening 1132-2 and the second opening 1132-3. The third segment 1131-3 is located inside the sliding groove 1132-1 and between the first opening 1132-2 and the support frame 111. It is worth noting that, for ease of illustration, the connection between the first segment 1131-1 and the second segment 1131-2 is not shown in the figure; the connection between the second segment 1131-2 and the third segment 1131-3 is also not shown in the figure.

[0051] Please combine Figure 5 refer to Figure 7 The structure shown can be increased when needed. Figure 3 When the dimensions of the annular structure shown are known, the support frame 111 can be pulled along direction a. At this time, Figure 7 The fixing point of the third segment 1131-3 and the support frame 111 moves synchronously along direction a, and the dimension of the third segment 1131-3 becomes shorter. Theoretically, the length of the third segment 1131-3 becomes redundant.

[0052] Accordingly, the second segment 1131-2 of the adjusting band 1131 moves in the opposite direction, i.e., direction b, with the portion wrapped between the through hole 1132-4 and the first opening 1132-2, and the portion wrapped between the through hole 1132-4 and the second opening 1132-3 as support points. Since the size of the second segment 1131-2 is roughly limited, the redundancy of the third segment 1131-3 can be transferred to the first segment 1131-1, so that the first segment 1131-1 can move in direction a, increasing its size, ensuring that the length of the adjusting band 1131 between the adjuster 1132 and the flexible binding member 112 is positively correlated with the length of the support frame 111 sliding out from the adjuster 1132.

[0053] When assembling the adjusting belt 1131 and the adjuster 1132, for example, the second end of the adjusting belt 1131 can be inserted into the sliding groove 1132-1 through the second opening 1132-3 and pass through the through hole 1132-4 to exit the sliding groove 1132-1; then, the second end of the adjusting belt 1131 can re-enter the sliding groove 1132-1 through the first opening 1132-2 and be fixed to the part of the support frame 111 located in the sliding groove 1132-1.

[0054] Of course, when setting the sliding connection structure between the support frame 111 and the adjuster 1132, the maximum sliding path of the support frame 111 in directions a and b needs to be limited, such as by setting a limiting structure on the support frame 111 and / or the adjuster 1132. For example, the limiting structure can be a locking tooth provided on the support frame 111 and / or the adjuster 1132 to limit the maximum pull-out size of the support frame 111 in direction a; or, the limiting structure can be a limiting boss provided on the support frame 111 to limit the maximum insertion size of the support frame 111 in the sliding groove 1132-1 in direction b.

[0055] In addition, it is worth noting that the opening size of the through hole 1132-4 can be set according to requirements to facilitate the insertion of the adjustment belt 1131 and ensure the stability of the adjustment belt 1131 during the size adjustment process, thereby improving the service life of the adjustment component 113 and enhancing the user experience.

[0056] Figure 8 This is a schematic diagram of the adjuster 1132 in the leg support structure 100 provided in an embodiment of this application. In some embodiments, such as Figure 8 As shown, the regulator 1132 includes a first part 1132a and a second part 1132b that are detachably connected. The first part 1132a and the second part 1132b cooperate to form a sliding groove 1132-1. A through hole 1132-4 is provided in the first part 1132a to facilitate the installation of the adjusting belt 1131 relative to the regulator 1132 and the assembly of the support frame 111 relative to the regulator 1132, thereby reducing assembly difficulty and improving assembly efficiency.

[0057] It is worth noting that, in this embodiment, the first opening 1132-2 and the second opening 1132-3 of the regulator 1132 are also formed by the cooperation of the first part 1132a and the second part 1132b. Figure 8As shown, the first part 1132a resembles a shell structure, and the second part 1132b is a block structure. This shell structure has openings on three sides. The second part 1132b closes the larger central opening to form a sliding groove 1132-1 with the first part 1132a. The second part 1132b also closes at least a portion of the smaller openings on both sides to form a first opening 1132-2 and a second opening 1132-3. A through hole 1132-4 is provided in the first part 1132a and is positioned opposite the larger opening.

[0058] In addition, such as Figure 8 As shown, for example, a notch or slot can be provided on the edge of the second part 1132b to facilitate assembly and fixation of the two. Of course, other connection structures can also be provided between the first part 1132a and the second part 1132b, which will not be described in detail here.

[0059] In addition, the regulator 1132 can also be an integral structure, which can be provided with a first opening 1132-2, a second opening 1132-3 and a through hole 1132-4.

[0060] In some embodiments, please combine Figure 3 refer to Figure 4 As shown in the diagram, the leg support structure 100 provided in this embodiment further includes a connecting component 130, through which the first leg support 110 and the second leg support 120 are connected; the connecting component 130 includes a first connector 131 and a second connector 132 corresponding to the first connector 131, wherein:

[0061] The first connector 131 is connected to the support frame 111 and / or the adjustment assembly 113, the second connector 132 is connected to the second leg support 120, and the second connector 132 is detachably connected to the first connector 131.

[0062] It should be noted that, in this embodiment of the application, the detachable connection between the first connector 131 and the second connector 132 can facilitate the user's putting on and taking off operations and improve the user experience; on the other hand, it can provide significant convenience for the connection between the first leg support 110, the second leg support 120, the support frame 111, and the adjustment component 113.

[0063] In some embodiments, please continue to combine Figure 3 refer to Figure 4 The structure shown includes a first connecting member 131, which includes a first connecting strip 1311 and a first plug-in part 1312. One end of the first connecting strip 1311 is connected to the support frame 111 or the adjustment assembly 113, and the other end of the first connecting strip 1311 is connected to the first plug-in part 1312.

[0064] The second connector 132 includes a second connecting strap 1321 and a second insertion part 1322. One end of the second connecting strap 1321 is connected to the second leg support 120, and the other end of the second connecting strap 1321 is connected to the second insertion part 1322. The first insertion part 1312 and the second insertion part 1322 are detachably connected. The detachable connection method can be a snap-fit ​​connection, a magnetic connection, etc.

[0065] In this embodiment, the flexible design of the first connecting strap 1311 and the second connecting strap 1321 makes the connection between the first connecting member 131 and the support frame 111 / adjustment component 113, and the connection between the second connecting member 132 and the second leg support 120 more adaptable. It can flexibly adapt to the installation angle and position of different components, avoid the installation limitations caused by rigid connection, and at the same time, it can buffer the slight force generated by leg movement during the use of the leg support, improving the comfort of use.

[0066] Meanwhile, the detachable connection between the first connector 1312 and the second connector 1322 can ensure the stability of the connection between the first connector 131 and the second connector 132, effectively preventing loosening and falling off during use, and can also simplify the disassembly and assembly operation. The docking or separation can be completed quickly without the aid of tools, making it convenient and efficient for daily adjustment of the leg support position or later maintenance and replacement of parts.

[0067] In some embodiments, please continue to combine Figure 3 refer to Figure 4 The structure shown has an adjustable length for the first connecting band 1311 between the first insertion portion 1312 and the first leg support 110; and / or, an adjustable length for the second connecting band 1321 between the second insertion portion 1322 and the second leg support 120.

[0068] It should be noted that, in this embodiment, the size adjustment of the first connecting strap 1311 and / or the second connecting strap 1321 will also affect the size of the ring structure. Before the user wears the leg support structure 100, preliminary adjustments can be made using the first connecting strap 1311 and / or the second connecting strap 1321, followed by fine adjustments using the adjustment component 113, further improving the flexibility and practicality of the leg support structure 100.

[0069] In some embodiments, please continue to combine Figure 3 refer to Figure 4As shown in the structure, the first leg support 110 also includes an auxiliary fixing plate 114 fixed to the surface of the flexible binding member 112; the flexible binding member 112 is connected to the support frame 111 and / or the adjustment component 113 through the auxiliary fixing plate 114. The auxiliary fixing plate 114 is fixed to the surface of the flexible binding member 112, which can distribute the connection force between the flexible binding member 112 and other components such as the support frame 111 and / or the adjustment component 113 to the auxiliary fixing plate 114, avoiding problems such as tearing and deformation of the flexible material due to local stress concentration, and improving the connection strength and service life of the flexible binding member 112.

[0070] Moreover, compared to the flexible binding member 112 being directly connected to other structures, the auxiliary fixing plate 114 can provide a more stable and flat connection interface, making the connection operation more precise and convenient, while reducing the loosening of the connection caused by the displacement of the flexible binding member 112, and ensuring the stability of the leg support structure 100.

[0071] In addition, the auxiliary fixing plate 114 can also shape the flexible binding member 112. When the leg support structure 100 supports the human leg, it can reduce excessive wrinkling or displacement of the flexible binding member 112 due to force, ensuring the fit and comfort of the leg support. Especially in long-term use scenarios, it can maintain the stable support effect of the leg support and further improve the user experience.

[0072] Of course, there are many choices for the materials used to prepare the fixing plate. For example, it can be a polypropylene plate (PP). PP plates have good structural strength and toughness, which can provide a stable support base for the flexible binding member 112, prevent the fixing plate from easily deforming or breaking during connection or stress, ensure the connection between the flexible binding member 112 and the support frame 111 / adjustment assembly 113, and also buffer stress when subjected to slight impact or vibration, reducing the impact on the overall structure.

[0073] In some embodiments, the flexible binding member 112 is an elastic mesh structure. When the flexible binding member 112 adopts an elastic mesh structure, its excellent elasticity allows it to closely conform to the contour of the bound human leg during the binding process, which can not only ensure a stable binding effect and prevent loosening and displacement, but also adaptively adjust the tightness according to the shape changes of the object or human body, effectively reducing local pressure and improving the comfort of use.

[0074] Meanwhile, the elastic mesh structure offers excellent breathability, preventing stuffiness and dampness caused by a confined space created by binding, especially during prolonged use, keeping the contact surface dry and breathable. Furthermore, the elastic mesh material possesses high toughness and tensile strength, resisting deformation or breakage with repeated use, thus extending the lifespan of the flexible binding component 112. The lightweight nature of the elastic mesh also helps reduce the weight of the leg support structure 100.

[0075] In this embodiment, the leg support structure 100 can simultaneously adjust its own size and adjust the fit of the flexible binding member 112 to improve the user's wearing experience. Furthermore, the position adjustment of the first leg support 110 can drive the elastic mesh structure that fits the leg to move and deform, thereby achieving a better wearing experience.

[0076] In some embodiments, the second leg support 120 is made of a flexible material.

[0077] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
