Description

Technical Field

[0001] This invention relates to the fields of mechanical manufacturing and wearable robot technology, and more specifically, to a binding structure connection device for wearable robots. Background Technology

[0002] Currently, wearable robots are tightly connected to the human body through a strap-on structure, applying the robot's driving force to the body to drive limb movements, providing assistance to workers or helping patients with rehabilitation training. The strap-on structure of wearable robots is generally made of fabric, which is a consumable part requiring regular maintenance and replacement. Furthermore, to achieve better assistive effects, the connection position between the strap-on structure and the robot needs to be adjusted according to the different body shapes of different users.

[0003] In existing technologies, the binding structure of wearable robots is mostly fixedly connected to the robot body, which usually requires special tools for repair and replacement, and disassembly is difficult and time-consuming; the binding structure is fixed in the installation position relative to the robot body, and it is impossible to quickly adjust the binding position between the user and the robot.

[0004] In summary, at least one of the following technical problems exists:

[0005] The binding structure of wearable robots is fixedly connected to the robot body, which makes maintenance and replacement time-consuming and prevents quick adjustment of the binding position. Summary of the Invention

[0006] The main objective of this invention is to provide a binding structure connection device for wearable robots, so as to solve the problems in the prior art where the binding structure of wearable robots is fixedly connected to the robot body, resulting in long maintenance and replacement times and the inability to quickly adjust the binding position.

[0007] To achieve the above objectives, according to one aspect of the present invention, a binding structure connection device for a wearable robot is provided, comprising:

[0008] A slotted slide rail is fixedly connected to the robot body.

[0009] A sliding base is connected to a binding structure and engages with a slotted slide rail. The sliding base slides in or out from one end or the other end of the slotted slide rail to separate and connect the binding structure to the robot body.

[0010] Preferably, the sliding base includes:

[0011] A sliding sleeve, which has a guide groove, slides along a slotted guide rail;

[0012] A base cover plate, which is fixedly installed on the sliding sleeve;

[0013] The slot locking blocks are arranged in pairs and symmetrically installed on the sliding sleeve, and slide along the direction perpendicular to the slot-type guide rail.

[0014] Compression springs, which are arranged in pairs and respectively disposed between the corresponding slot locking blocks and the base cover plate;

[0015] A locking lever is installed between the sliding sleeve and the base cover plate;

[0016] The switch springs are symmetrically installed between the sliding sleeve and the base cover plate.

[0017] Preferably, the slotted slide rail has an array of trapezoidal slots.

[0018] Preferably, the sliding sleeve is provided with a double-sided locking and limiting structure.

[0019] Preferably, during the sliding of the sliding base along the slotted slide rail, the locking block retracts into the interior of the sliding base under the force of the trapezoidal inclined surface, ensuring that the sliding base can slide freely on the slotted slide rail.

[0020] Preferably, when the sliding base slides along the slotted slide rail to a certain position, the slot locking block pops out into the trapezoidal groove of the slotted slide rail under the action of the compression spring, thereby realizing the position adjustment.

[0021] Preferably, when the locking lever is in the unlocked position, the locking block can retract into the interior of the sliding base, allowing the sliding base to slide freely on the slotted guide rail.

[0022] Preferably, when the locking lever is moved to the locking position, it can block the retraction movement of the locking block in the slot. At this time, the sliding base is fixed in a certain position of the slot-type guide rail, thus achieving locking.

[0023] Preferably, when the locking lever is toggled to switch between locked and unlocked states, the first half of the movement compresses the switch spring, and the second half of the movement, under the elastic force of the switch spring, helps the locking lever slide into place.

[0024] Preferably, the base cover is fixedly connected to the sliding sleeve by screws.

[0025] The technical solution of this invention has the following technical effects:

[0026] By using slotted slide rails and sliding bases together, the wearable robot strapping structure can be quickly assembled and disassembled from the robot body, facilitating the maintenance and replacement of the strapping structure. By setting slotted slide rails of different lengths, the position of the wearable robot strapping structure relative to the robot body can be adjusted over a wide range, thus better adapting to users of different body types. The locking lever on the sliding base can lock the position of the wearable robot strapping structure relative to the robot body, achieving a stable and reliable force transmission effect.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 5As shown, this embodiment of the invention provides a binding structure connection device for a wearable robot, including: a slotted slide rail 1, which is fixedly connected to the robot body; and a sliding base 2, which is connected to the binding structure and cooperates with the slotted slide rail 1. The sliding base 2 slides into or out of one end of the slotted slide rail 1 to separate and connect the binding structure to the robot body.

[0037] In this embodiment, the slotted slide rail 1 serves as a guide and is fixedly connected to the robot body for connection with the robot. The sliding base 2 provides support and is connected to the binding structure. The sliding base 2 cooperates with the slotted slide rail 1 to achieve a sliding connection. The sliding base 2 slides in or out from one end of the slotted slide rail 1, separating and connecting the binding structure to the robot body, enabling quick connection and separation from both ends.

[0038] In this embodiment, the sliding base 2 includes: a sliding sleeve 21, a base cover plate 24, a slot locking block 25, a compression spring 26, a locking lever 23, and a switch spring 22. The sliding sleeve 21 is used to cooperate with the slot-type slide rail 1. The sliding sleeve 21 is provided with a guide groove, which serves as a guide, allowing the sliding sleeve 21 to slide along the slot-type guide rail.

[0039] The base cover plate 24 serves a sealing function and is fixedly installed on the sliding sleeve 21; the slot locking block 25 serves a locking function, and the slot locking blocks 25 are arranged in pairs and symmetrically installed on the sliding sleeve 21, and slide along the direction perpendicular to the slot guide rail; the compression spring 26 is arranged in pairs and is respectively set between the corresponding slot locking block 25 and the base cover plate 24; the locking lever 23 is installed between the sliding sleeve 21 and the base cover plate 24; the switch spring 22 is symmetrically installed between the sliding sleeve 21 and the base cover plate 24.

[0040] In this embodiment, the slotted slide rail 1 has an array of trapezoidal grooves. The sliding sleeve 21 is equipped with a double-sided locking and limiting structure. During the sliding of the sliding base 2 along the slotted slide rail 1, the slot locking block 25 retracts into the interior of the sliding base 2 under the force of the trapezoidal inclined surface, ensuring that the sliding base 2 can slide freely on the slotted slide rail 1. When the sliding base 2 slides to a certain position along the slotted slide rail 1, the slot locking block 25 pops out into the trapezoidal groove of the slotted slide rail 1 under the action of the compression spring 26, realizing position adjustment. When the locking lever 23 is in the unlocked position, the slot locking block 25 can retract into the interior of the sliding base 2, allowing the sliding base 2 to slide freely on the slotted guide rail.

[0041] In this embodiment, when the locking lever 23 is moved to the locked position, it blocks the retracting movement of the locking block 25 in the slot. At this time, the sliding base 2 is fixed in a certain position on the slot-type guide rail, achieving locking. When the locking lever 23 is moved to switch between locked and unlocked states, the first half of the movement compresses the switch spring 22, and the second half of the movement, under the elastic force of the switch spring 22, helps the locking lever 23 slide into place. The base cover plate 24 is fixedly connected to the sliding sleeve 21 by screws.

[0042] Specifically, a slot-type guide rail is installed on the wearable robot body. The slot-type slide rail 1 has an array of trapezoidal slots. The sliding base 2 is connected to the binding structure. The sliding base 2 is provided with a sliding sleeve 21, which has a guide groove that cooperates with the slot-type slide rail 1, allowing the sliding base 2 to slide into or out of either end of the slot-type slide rail 1. The sliding base 2 is provided with a slot locking block 25. A compression spring 26 is provided between the slot locking block 25 and the base cover plate 24. The slot locking block 25 maintains a certain elastic force under the action of the compression spring 26. When the sliding base 2 slides relative to the slot-type slide rail 1, the slot locking block 25 can retract into the sliding base 2 through the force of the trapezoidal inclined surface, ensuring that the sliding base 2 can slide into or out of the slot-type slide rail 1. The sliding base 2 slides freely on the slotted slide rail 1. When the sliding base 2 slides to a certain position, the slot locking block 25 pops out into the trapezoidal groove of the slotted slide rail 1 under the action of the compression spring 26, completing the position adjustment. The sliding base 2 is provided with a locking lever 23, which can slide within the space formed by the sliding sleeve 21 and the base cover plate 24. When the locking lever 23 is in the unlocked state, the slot locking block 25 can be compressed into the sliding base 2, allowing the sliding base 2 to slide freely on the slotted guide rail. When the locking lever 23 is in the locked state, the locking lever 23 restricts the retraction space of the slot locking block 25, fixing the sliding base 2 to a certain position on the slotted guide rail, thus achieving the locking function. The slotted slide rail 1 can be extended to different lengths according to the user's needs, realizing a wide range of adjustment of the position of the binding structure relative to the robot body. The sliding base 2 has a guide structure within the mounting space of the slot locking block 25, ensuring that the slot locking block 25 can only move in a direction perpendicular to the slot-type slide rail 1. The sliding base 2 also has a limiting structure within the mounting space of the slot locking block 25, ensuring that the slot locking block 25 will not dislodge from the sliding base 2. The sliding base 2 has two symmetrical mounting spaces for the slot locking blocks 25, achieving a stable and reliable connection by installing the two slot locking blocks 25. The sliding base 2 contains two symmetrical switch springs 22, providing a certain rebound force for the locking lever 23 during state switching, and maintaining it in the locked or unlocked state without external force. The sliding sleeve 21 has a double-sided locking limiting structure, ensuring that the locking lever 23 reaches the limiting position in the locked or unlocked state, guaranteeing the accuracy of the locking lever 23's operating position. The base cover plate 24 is fixedly connected to the sliding sleeve 21 with screws, providing mounting space for the compression spring 26 and maintaining the compression spring 26 in a compressed state.

[0043] like Figure 1 As shown, it includes a slotted slide rail 1 and a sliding base 2. The slotted slide rail 1 is fixedly connected to the robot body, and the sliding base 2 is fixedly connected to the binding structure. The sliding base 2 can slide into or out from either end of the slotted slide rail 1 to separate the binding structure from the robot body.

[0044] like Figure 2 As shown, in this embodiment, the sliding base 2 includes a sliding sleeve 21, a switch spring 22, a locking lever 23, a base cover plate 24, a slot locking block 25, and a compression spring 26. The sliding sleeve 21 has a guide groove, allowing it to slide along the slot-type guide rail. The slot locking blocks 25 are symmetrically mounted on the sliding sleeve 21 and can slide perpendicular to the guide rail. The base cover plate 24 is fixedly mounted on the sliding sleeve 21. Two compression springs 26 connect each slot locking block 25 to the base cover plate 24, maintaining a certain spring force on the slot locking block 25 under the action of the compression springs 26. The locking lever 23 is installed between the sliding sleeve 21 and the base cover plate 24, allowing it to slide along the guide rail. The switch spring 22 is symmetrically installed between the sliding sleeve 21 and the base cover plate 24, providing a certain rebound force during the sliding of the locking lever 23.

[0045] like Figure 3 As shown, in this embodiment, the slotted slide rail 1 has an array of trapezoidal grooves. During the sliding process of the sliding base 2 along the slotted slide rail 1, the slot locking block 25 can be retracted into the interior of the sliding base 2 by the force of the trapezoidal inclined surface, ensuring that the sliding base 2 can slide freely on the slotted slide rail 1. When the sliding base 2 slides to a certain position along the slotted slide rail 1, the slot locking block 25 pops out into the trapezoidal groove of the slotted slide rail 1 under the action of the compression spring 26, realizing the position adjustment.

[0046] like Figure 4 and Figure 5 As shown, in this embodiment, when the locking lever 23 is in the unlocked position, the slot locking block 25 can retract into the sliding base 2, allowing the sliding base 2 to slide freely on the slot-type guide rail. By moving the locking lever 23 to the locked position, it blocks the retraction movement of the slot locking block 25, at which point the sliding base 2 is fixed at a certain position on the slot-type guide rail, thus achieving the locking function. During the process of switching between the locked and unlocked states by moving the locking lever 23, the first half of the movement compresses the switch spring 22, and the second half, under the elastic force of the switch spring 22, helps the locking lever 23 slide into place, preventing the locking lever 23 from being stuck in the middle state, which would cause an unsmooth switching between the locked and unlocked states.

[0047] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0048] By using the slotted slide rail 1 and the sliding base 2 together, the wearable robot binding structure can be quickly disassembled and assembled with the robot body, facilitating the maintenance and replacement of the binding structure. By setting different lengths of the slotted slide rail 1, the position of the wearable robot binding structure relative to the robot body can be adjusted over a wide range, thus better adapting to people of different body types. The locking lever 23 on the sliding base 2 can lock the position of the wearable robot binding structure relative to the robot body, achieving a stable and reliable force transmission effect.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
