[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 9As shown, the exoskeleton auxiliary hanger involved in the present invention includes a chassis 1, a vertical guide frame 2 installed on the chassis 1, and an armrest device 3 slidably installed on the vertical guide frame 2, and the armrest device 3 is used to connect the exoskeleton robot 6. For the convenience of description. In the following embodiment, the width direction of the armrest device 3 is defined as the left-right direction, the sliding direction of the armrest device 3 is defined as the up-down direction, and the direction orthogonal to the front-back direction and the up-down direction is defined as the front-back direction. Based on this, Figure 3 In the view shown, the left and right sides of the paper are the rear and front directions respectively, the upper and lower sides of the paper are the upper and lower directions respectively, and the inside and outside of the paper are the right and left directions respectively.
[0034] like Figures 1 to 3 As shown, the armrest device 3 includes a lever arm connector 32 and two lever arms 31 ; wherein the lever arm connector 32 is slidably disposed on the vertical guide rail frame 2 to enable the entire armrest device 3 to slide up and down.
[0035] like Figures 4 to 7 As shown, the lever arm connecting member 32 is provided with two groups of vertical slide rails 322a spaced apart in the left and right directions, and the two lever arms 31 are slidably mounted on the two groups of vertical slide rails 3232, so that the lever arms 31 can slide vertically relative to the lever arm connecting member 32; a spring support seat 3231 is provided under each lever arm 31, and the spring support seats 3231 are all mounted on the lever arm connecting member 32; a vertical spring 33 is provided between the spring support seat 3231 and the lever arm 31 above it, and the vertical spring 33 is compressed when the lever arm 31 moves downward; when the exoskeleton robot 6 drives the patient During walking exercise, the lever arm 31 can float up and down following the patient's corresponding hip, thereby improving the patient's walking comfort; and the setting of the vertical spring 33 can effectively reduce the impact on the patient's hip when floating upward; in addition, a lever arm detection sensor 34 is provided on the lever arm connector 32, and the lever arm detection sensor 34 is an existing position detection sensor such as a proximity switch or a distance sensor. The position of the lever arm 31 is detected by the lever arm detection sensor 34 to determine the degree of compression of the vertical spring 33; in this embodiment, the lever arm detection sensor 34 is preferably a proximity switch.
[0036] Since the length of the calf and thigh of each patient is different, the height of the armrest device 3 and the leg length of the exoskeleton robot 6 need to be adjusted according to the conditions of different patients to meet the needs of different patients. At present, the height adjustment amount of the armrest device 3 and the leg length adjustment amount of the exoskeleton robot 6 are completely confirmed by human observation, and it is very easy to have the situation of inadequate adjustment; when the patient has exercise needs, the exoskeleton robot 6 must first be connected to the arm 31 in the armrest device 3, and the armrest device 3 must be moved up to the state where the exoskeleton robot 6 is suspended, and then the patient must be docked with the exoskeleton robot 6 on the exoskeleton auxiliary hanger (that is, the patient stands on the soles of the exoskeleton robot 6), and then the legs of the exoskeleton robot 6 are adjusted according to the patient's leg conditions, and the connection with the exoskeleton robot 6 is completed; in this process, the exoskeleton robot 6 starts Finally, the armrest device 3 is in a suspended state, so that the vertical spring 33 is compressed under the weight of the exoskeleton robot 6 and the patient, and the lever 31 is away from the lever arm detection sensor 34; finally, the armrest device 3 is adjusted so that the armrest device 3 drives the exoskeleton robot 6 and the patient to descend together. When the sole of the exoskeleton robot 6 contacts the ground, the weight on the vertical spring 33 disappears (the weight is borne by the ground), so that the vertical spring 33 is reset and pushes the lever arm 31 upward; when the lever arm detection sensor 34 senses the upward lever arm 31, it indicates that the height of the armrest device 3 has been adjusted to the right position, effectively overcoming the problem of inaccurate adjustment when observing the adjustment situation with the naked eye in the traditional way.
[0037] Therefore, the present application uses the arm detection sensor 34 to sense the arm 31 to identify the degree of compression of the vertical spring 33, so as to determine whether the patient wearing the exoskeleton robot 6 on the armrest device 3 is in a suspended state or in a grounded state, thereby facilitating accurate determination of whether the height of the armrest device 3 is adjusted in place, effectively avoiding the shortcomings of traditional adjustment based on naked eye observation.
[0038] Further, if Figure 5 and Figure 6As shown, the arm connecting member 32 includes a back plate 321, a left mounting plate 323a and a right mounting plate 323b. The back plate 321 is provided with a left transverse guide rail 322a and a right transverse guide rail 322b; the left mounting plate 323a is slidably mounted on the left transverse guide rail 322a, and the right mounting plate 323b is slidably mounted on the left transverse guide rail 322a, and the back plate 321 is provided with a synchronous adjustment component that allows the left mounting plate 323a and the right mounting plate 323b to move synchronously closer or farther away; the left mounting plate 323a and A set of vertical slide rails 3232 is provided on each of the right mounting plates 323b, and a force arm connecting seat 311 is slidably mounted on each set of vertical slide rails 3232; the two force arms 31 are fixed on the two force arm connecting seats 311 respectively, so that the two force arms 31 can be vertically slidably mounted on the left mounting plate 323a and the right mounting plate 323b respectively; a spring support seat 3231 is installed on each of the left mounting plate 323a and the right mounting plate 323b, and the spring support seat 3231 is located below the corresponding force arm connecting seat 311 ; A vertical spring 33 is provided above each spring support 3231, and the two ends of the vertical spring 33 are respectively in contact with the spring support seat 3231 and the corresponding force arm connecting seat 311, so as to couple the vertical spring 33 between the spring support seat 3231 and the corresponding force arm 31; a force arm detection sensor 34 is installed on at least one mounting plate, and the force arm detection sensor 34 is located above the corresponding force arm connecting seat 311; when the armrest device 3 is high and the patient is suspended in the air, the vertical spring 33 will be compressed under the action of the weight of the exoskeleton robot and the patient's own weight. When the armrest device 3 is lowered to the bottom of the patient's feet and contacts the ground, the weight of the exoskeleton robot and the patient's own weight are borne by the ground, so that the vertical spring 33 resets and pushes the corresponding force arm 31 to move up close to the corresponding force arm detection sensor 34; the force arm detection sensor 34 is used to determine whether the position height of the armrest device 3 is appropriate; in this embodiment, the left transverse guide rail 322a and the right transverse guide rail 322b are separately provided or connected to form a transverse guide rail.
[0039] It is understandable that there are many types of lever arm detection sensors 34 , which may be proximity sensors, laser ranging sensors, inductive ranging sensors, etc., without limitation. In this embodiment, the lever arm detection sensor 34 is a proximity sensor.
[0040] It is understandable that the synchronous adjustment component can be in various forms, including but not limited to the following two forms:
[0041] The first setting form: Figure 5As shown, the synchronous adjustment component includes a first push rod 324a, a second push rod 324b and an intermediate rotating rod 325; the left end of the first push rod 324a is hinged to the left mounting plate 323a, and the right end of the second push rod 324b is hinged to the right mounting plate 323b; the first push rod 324a is parallel to the second push rod 324b, and the right end of the first push rod 324a and the left end of the second push rod 324b are respectively hinged to different positions of the intermediate rotating rod 325; the intermediate rotating rod 325 is rotatably set on the back plate 321 to realize the synchronous approach or synchronous distance of the left mounting plate 323a and the right mounting plate 323b.
[0042] The second setting form: the synchronous adjustment component includes a first rack 326a, a second rack 326b and an intermediate gear 327 rotatably set on the back plate 321; the first rack 326a is fixed on the left mounting plate 323a, and the second rack 326b is fixed on the right mounting plate 323b; the first rack 326a is parallel to the second rack 326b, and the first rack 326a and the second rack 326b are both in transmission engagement with the intermediate gear 327; in this way, when the intermediate gear 327 rotates, the left mounting plate 323a and the right mounting plate 323b can be synchronously approached or synchronously moved away.
[0043] Further, if Figure 1 、 Figure 2 and Figure 8 As shown, the chassis 1 is composed of two load-bearing beams 11 arranged at intervals along the left and right directions, and each load-bearing beam 11 is provided with a vertical guide rail frame 2; a movable seat 4 is slidably installed on each vertical guide rail frame 2, and the two movable seats 4 are fixedly connected to the left mounting plate 323a and the right mounting plate 323b respectively; when the distance between the left mounting plate 323a and the right mounting plate 323b is adjusted, the distance between the two vertical guide rail frames 2 can be adjusted at the same time; that is, when the exoskeleton auxiliary hanger is idle or transferred upstairs and downstairs, the width of the entire exoskeleton auxiliary hanger can be adjusted so that the width of the exoskeleton auxiliary hanger is reduced to the length of the backboard 321 (generally 0.6m~0.7m), which is convenient for reducing the occupied space and also convenient for the exoskeleton auxiliary hanger to enter and exit narrow elevators for transfer between downstairs and upstairs; in order to reduce the difficulty of adjusting the width of the exoskeleton auxiliary hanger and facilitate the follow-up exercise of the exoskeleton auxiliary hanger, universal wheels are provided at the bottom of the two load-bearing beams 11.
[0044] like Figure 6 As shown, the vertical guide rail frame 2 includes at least one vertical guide rail 21, and the movable seat 4 is slidably installed on the vertical guide rail 21 of the corresponding vertical guide rail frame 2; in this embodiment, each vertical guide rail frame 2 has two vertical guide rails 21, and the two vertical guide rails 21 need to be spaced apart in the front-to-back direction to avoid increasing the minimum width of the exoskeleton auxiliary hanger.
[0045] It can be understood that the guide rails in the present invention have various cross-sectional shapes, such as rectangular, circular, dovetail, triangular and other shapes, and the guide rails with different cross-sectional shapes all belong to the technical features protected by the present invention; the optical axis of the circular cross-section in the accompanying drawings is only one of the forms of expression, and is not a specific limitation on the content of protection.
[0046] In order to reduce the difficulty of adjusting the height of the armrest device 4, each movable seat 4 is provided with a movable seat lifting device that drives the movable seat 4 to move up and down. The movable seat lifting device is controlled by a controller to achieve synchronous lifting of the two movable seats 4.
[0047] It is understandable that the movable seat lifting device can be in various forms, including but not limited to hydraulic rods, pneumatic push rods, electric push rods, motor + screw, gear + rack, etc. In this embodiment, the preferred structure of the movable seat lifting device is as follows: Figure 8 As shown, it includes a vertical screw 51, a screw nut 52 mounted on the vertical screw 51 and a screw motor 53 for driving the vertical screw 51 to rotate; wherein the screw nut 52 is fixedly connected to the corresponding movable seat 4; the vertical screw 51 is located between the two vertical guide rails 21 in the corresponding vertical guide rail frame 2, the tops of the two vertical guide rails 21 are connected to the screw top plate 511, the lower parts of the two vertical guide rails 21 are connected through the screw bottom plate 512, and the two ends of the vertical screw 51 are respectively rotatably mounted on the screw top plate 511 and the screw bottom plate 512; the screw motor 53 is preferably arranged on the screw top plate 511 and connected to the vertical screw 51; in addition to playing the role of installing the vertical screw 51, the screw top plate 511 and the screw bottom plate 512 are also used to achieve a reinforced connection between the two vertical screws 51.
[0048] Since the screw motor 53 generates vibration and noise during operation, in order to prevent the vibration and noise of the screw motor 53 from disturbing the patient, the screw motor 53 needs to be installed on the screw top plate 51 through a shock-absorbing bracket, and a noise-isolating cover that covers the screw motor 53 is installed on the screw top plate 51.
[0049] In order to improve the aesthetics of the entire exoskeleton auxiliary hanger, a bracket shell is provided under the partition cover to cover the vertical screw 51 and the vertical guide rail 21, a fixed shielding shell is provided on the back plate 321 to block the synchronous adjustment component, and a follower shielding shell that slides with the fixed shielding shell is provided on the left mounting plate 323a and the right mounting plate 323b; the fixed shielding shell and the follower shielding shell cooperate to block various components on the force arm connector 32 except the force arm 31.
[0050] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
[0051] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
