Description

Technical Field

[0001] This utility model belongs to the field of robot design, and more specifically relates to a leg plate mechanism applied to a hip joint assistive exoskeleton. Background Technology

[0002] An assistive exoskeleton is a walking aid that enhances the human body's endurance or reduces metabolic costs. It recovers the mechanical energy generated by the human body's own walking and converts it into elastic potential energy through its mechanical structure.

[0003] The existing leg plate mechanisms of hip joint assistive exoskeletons mostly hinge one end of the leg rod to the motor and the other end to the leg plate. The leg plate is generally equipped with a cover plate, leg plate cover plate, connectors and other parts. Not only is the structural rigidity poor, but it also does not have the function of installing leg straps. Therefore, it cannot guarantee the compatibility of subsequent leg straps and the comfort of wearing them. Utility Model Content

[0004] The main purpose of this utility model is to provide a device that can achieve higher structural rigidity, has the function of installing leg wraps, and can ensure compatibility and wearing comfort for users with different leg sizes.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A leg plate mechanism for a hip joint assistive exoskeleton includes a leg rod, a leg binding mounting assembly, and a protective assembly. One end of the leg rod is provided with a leg plate, which is an integral component of the leg rod. The leg binding mounting assembly includes leg binding mounting holes respectively provided on the left and right sides of the leg plate and multiple sets of ventilation components provided between the two leg binding mounting holes. The protective assembly includes arc-shaped flaps respectively provided on the upper and lower sides of the leg plate. The length of the arc-shaped flaps is less than the length of the leg plate, and the maximum lateral length of each set of ventilation components is less than the length of the arc-shaped flaps.

[0007] According to a first aspect of the present invention, the leg rod is spiral-shaped, and the end of the leg rod away from the leg plate is provided with a mounting hole that can be hinged to the energy storage device.

[0008] According to a first aspect of the present invention, each group of the breathable components includes at least three breathable holes arranged along the length direction of the leg plate.

[0009] According to a first aspect of the present invention, the distance between adjacent upper and lower breathable components is less than or equal to the inner diameter of the breathable hole.

[0010] According to a first aspect of the present invention, the distance between the vent holes at both ends of the vent components in the same group and the corresponding leg strap mounting holes is less than the inner diameter of the vent holes in that group.

[0011] According to a first aspect of the present invention, the ventilation holes located in the middle of each group of ventilation components are correspondingly arranged with the leg rods.

[0012] According to a first aspect of the present invention, the leg strap mounting hole is provided along the height direction of the leg plate, and the diameter height of the leg strap mounting hole is smaller than the height of the leg plate.

[0013] According to a first aspect of the present invention, the concave surfaces of both arc-shaped flaps are arranged in a direction away from the leg rod.

[0014] According to a first aspect of the present invention, the arc-shaped flap, the leg bar, and the leg plate are all integral components.

[0015] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0016] This invention integrates the leg plate and leg bar into a single component, simplifying the manufacturing process, reducing the number of parts, and ensuring overall structural rigidity. The curved flaps on the upper and lower sides of the leg plate, with a length less than the leg plate itself, prevent stress concentration and compression when the upper or lower edge of the leg plate contacts the leg, thus improving wearing comfort. Furthermore, the leg-binding mounting holes on both sides of the leg plate, and the multiple sets of breathable components between them, increase breathability and prevent stuffiness when the leg plate is worn close to the leg.

[0027] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0028] See attached document Figure 1 To be continued Figure 4 As shown, a leg plate mechanism for a hip joint assistive exoskeleton includes a leg bar 1, a leg plate 2 disposed at one end of the leg bar, a leg binding mounting assembly 3, and a protective assembly 4.

[0029] In one embodiment of this utility model, the leg rod 1 is spiral-shaped, and the end of the leg rod 1 away from the leg plate 2 is provided with a mounting hole 5 that can be hinged to the energy storage device. The leg plate 2 and the leg rod 1 are integrated components, which not only simplifies the process and reduces the number of parts, but also ensures the rigidity of the overall structure.

[0030] In one embodiment of this utility model, the leg-binding mounting component 3 includes leg-binding mounting holes 31 respectively provided on the left and right sides of the leg plate 2 and multiple sets of breathable components provided between the two leg-binding mounting holes 31. The leg-binding mounting holes 31 are arranged along the height direction of the leg plate 2, which can increase the breathability of the leg plate 2 when it fits the human leg and avoid stuffiness.

[0031] In one embodiment of this utility model, each group of breathable components includes three breathable holes 32 arranged along the length direction of the leg plate 2, and the breathable hole 32 located in the middle position of each group of breathable components is correspondingly arranged with the leg bar 1, thereby effectively increasing the breathability of the leg plate 2 when wearing the human leg.

[0032] In one embodiment of this utility model, the distance between adjacent upper and lower breathable components is set to be less than or equal to the inner diameter of the breathable hole 32, the distance between the breathable holes 32 at both ends of the same group of breathable components and the corresponding leg strap mounting holes 31 is set to be less than the inner diameter of the breathable holes 32 of that group, and the maximum lateral length of each group of breathable components is set to be less than the length of the arc-shaped flap 41, so as to maximize the number of breathable holes 32 within the effective contact area between the leg plate 2 and the human leg, thereby ensuring the best heat dissipation and breathability effect.

[0033] In one embodiment of this utility model, the protective component 4 includes arc-shaped flaps 41 respectively disposed on the upper and lower sides of the leg plate 2. The length of the arc-shaped flaps 41 is less than the length of the leg plate 2, which can prevent the upper or lower edge of the leg plate 2 from contacting the human leg when wearing the leg plate 2, thus avoiding stress concentration and squeezing of the human leg, thereby effectively improving wearing comfort.

[0034] In one embodiment of this utility model, by providing leg-binding mounting holes 31 on the left and right sides of the leg plate 2, and setting the hole diameter and height of the leg-binding mounting holes 31 to be smaller than the height of the leg plate 2, the leg-binding mounting holes 31 can be prevented from breaking due to subsequent pulling of the leg-binding components while ensuring the installation of the leg-binding components, thereby effectively improving safety.

[0035] In one embodiment of this utility model, the arc-shaped flap 41, the leg bar 1, and the leg plate 2 are all integral components, and the concave surfaces of the two arc-shaped flaps 41 are arranged in a direction away from the leg bar 1. This can prevent the upper or lower edge of the leg plate 2 from contacting the human leg when wearing the leg plate 2, thus avoiding stress concentration and compression of the human leg.

[0036] This leg plate mechanism integrates the leg plate 2 and the leg rod 1 into a single component, which not only simplifies the manufacturing process and reduces the number of parts, but also ensures the overall structural rigidity. By setting arc-shaped flaps 41 on the upper and lower sides of the leg plate 2, and setting the length of the arc-shaped flaps 41 to be less than the length of the leg plate 2, it can avoid the situation where the upper or lower edge of the leg plate 2 contacts the human leg when people of different thicknesses wear the leg plate 2, thus preventing stress concentration and compression of the human leg, thereby improving wearing comfort. By setting leg binding mounting holes 31 on the left and right sides of the leg plate 2, and setting multiple sets of breathable components between the two leg binding mounting holes 31, the breathability of the leg plate 2 when wearing it in close contact with the human leg can be increased, avoiding stuffiness.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
