Description

Technical Field

[0001] This utility model relates to the field of rehabilitation exoskeleton technology, and in particular to a waterproof sealing structure for rehabilitation exoskeletons. Background Technology

[0002] Rehabilitation exoskeletons are cutting-edge devices that assist patients in their rehabilitation. They simulate human joint movements through mechanical structures and provide auxiliary force to the patient's limbs with a power system. However, they have many problems in use. Technically, they rely on battery power, which has a short battery life and slow charging. They are not accurate enough in capturing human movement intentions, and the mechanical parts are prone to wear. In terms of physiological adaptation, they are not comfortable to wear, which can affect muscles and bones and may also cause skin problems. In terms of practical use, they have poor adaptability to complex environments, are complicated to operate and difficult to learn, and have high maintenance costs.

[0003] However, joints are mostly made of metal. When exposed to air for a long time, they are susceptible to corrosion from moisture and sweat. Taking the knee joint as an example, the lack of sealing between the connecting shaft and the joint shell means that moisture and human sweat in daily use can cause the metal surface to rust, reduce the strength of the parts, shorten the service life, and even cause safety accidents due to damage to the parts during exercise. Utility Model Content

[0004] The purpose of this invention is to address the problem that in existing technologies, joints are mostly made of metal, which are easily corroded by moisture and sweat when exposed to air for a long time. Taking the knee joint as an example, the lack of a seal between the connecting shaft and the joint shell means that moisture and human sweat in daily use can cause the metal surface to rust, reduce the strength of the components, shorten the service life, and even cause safety accidents due to component damage during exercise. Therefore, this invention proposes a waterproof sealing structure for rehabilitation exoskeletons.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a waterproof sealing structure for a rehabilitation exoskeleton, comprising a first leg and a sealing device, wherein a second leg is rotatably mounted on the upper surface of the first leg, the sealing device is disposed on the surface of the second leg, the sealing device includes a fixing plate, the fixing plate being fixedly connected to the second leg, a rubber sleeve being fixedly connected to the lower surface of the fixing plate, the rubber sleeve being sleeved at the pivot of the second leg and the first leg, an iron plate being fixedly connected to the lower surface of the rubber sleeve, and a magnetic plate being fixedly connected to the upper surface of the first leg. A fixing rod is fixedly connected to the upper surface. A hole is opened on the surface of the iron plate. The fixing rod is inserted into the hole on the surface of the iron plate. A recycling component is provided on the surface of the iron plate. By setting a sealing device, the iron plate is attracted and fixed by magnetic plate, and further stabilized by threaded rod, so that the sealing sleeve can be tightly fitted at the pivot of the first and second legs. This structure forms a reliable sealing space, which greatly reduces the entry of water vapor into the joint, prevents electronic components from being damaged by short circuit due to water vapor, reduces the rust and corrosion of mechanical parts due to water vapor, thereby extending the service life of the exoskeleton joint and ensuring its stable operation.

[0006] Preferably, the magnetic plate is magnetically connected to the iron plate, and a mounting bracket is fixedly connected to the upper surface of the magnetic plate. By setting the magnetic plate, when the iron plate is pulled, the magnetic plate can attract the iron plate, so that the iron plate is initially fixed in the initial position, which facilitates subsequent operations, such as rotating the rocker arm or threaded rod to further fix the iron plate.

[0007] Preferably, a rocker arm is rotatably connected to the upper surface of the mounting bracket. The surface of the rocker arm has a threaded hole. By setting the rocker arm, when the iron plate is pulled and attracted to the magnetic plate, and the fixing rod is inserted into the iron plate, the rocker arm is rotated to move it above the iron plate. This action achieves precise positioning of the iron plate by the rocker arm, creating conditions for subsequent rotation of the threaded rod to clamp and fix the iron plate and the magnetic plate. The rocker arm is like a positioning rod, ensuring that the threaded rod can accurately abut against the iron plate, thereby stably fixing the iron plate on the magnetic plate. This ensures that the sealing sleeve can be accurately fitted onto the pivot of the first leg and the second leg, achieving a reliable seal and preventing moisture from entering.

[0008] Preferably, the rocker arm has a threaded rod connected to its surface. The threaded rod abuts against the iron plate. By setting the threaded rod, rotating the threaded rod to make it abut against the iron plate can clamp and fix the iron plate and the magnetic plate, thereby sealing the pivot of the first leg and the second leg with a sealing sleeve, effectively reducing the entry of moisture and playing a role in sealing and protecting the joint.

[0009] Preferably, there are two threaded rods, which are arranged symmetrically.

[0010] Preferably, the recycling component includes a rope with a ring fixedly connected to one side. By setting up the recycling component, when it is necessary to inspect and maintain the joint, rotating the threaded rod separates the iron plate from the magnetic plate, which can easily release the sealing device. By pulling the rubber sleeve upward and using the ring to fit on the hanging rod, the rubber sleeve can be quickly retracted, making the joint fully exposed. This facilitates maintenance personnel to carry out comprehensive inspection, cleaning, and component replacement, greatly improving maintenance efficiency.

[0011] Preferably, a hanging rod is fixedly connected to the upper surface of the fixing plate, and the ring is sleeved with the hanging ring. By setting the ring, the rubber sleeve can be easily and quickly retracted when inspecting and maintaining the joint, and the rubber sleeve can be retracted and put on the hanging rod, reducing the obstruction of operation by the rubber sleeve during maintenance.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a sealing device, during use, the iron plate is pulled to attract the magnetic plate, and at the same time, the fixing rod is inserted into the iron plate. Then, the rocker arm is rotated until it reaches above the iron plate. Then, the threaded rod is rotated, and the threaded rod abuts against the iron plate, clamping and fixing the iron plate and the magnetic plate. At this time, the sealing sleeve seals the pivot of the first and second legs, reducing the entry of moisture. By setting a sealing device, using the iron plate and the magnetic plate to attract and fix, and further stabilizing it with the threaded rod, the sealing sleeve can be tightly fitted at the pivot of the first and second legs. This structure forms a reliable sealing space, greatly reducing the entry of moisture into the joint area, preventing electronic components from being damaged by short circuits due to moisture, reducing the rust and corrosion of mechanical parts due to moisture erosion, thereby extending the service life of the exoskeleton joint and ensuring its stable operation.

[0014] 2. In this utility model, by setting up a recycling component, when it is necessary to inspect and maintain the joint between the first and second legs, the threaded rod is rotated to disengage from the iron plate. At this time, the iron plate is pulled apart from the magnetic plate. Then, the rubber sleeve is pulled upwards, and the ring is placed on the hanging rod to retract the rubber sleeve. By setting up the recycling component, when it is necessary to inspect and maintain the joint, rotating the threaded rod to separate the iron plate from the magnetic plate can easily release the sealing device. Pulling the rubber sleeve upwards and using the ring to place it on the hanging rod can quickly retract the rubber sleeve, making the joint fully exposed. This facilitates maintenance personnel to carry out comprehensive inspection, cleaning, and component replacement, greatly improving maintenance efficiency. Attached Figure Description

[0021] Please see Figures 1-5 This utility model provides a technical solution: a waterproof sealing structure for rehabilitation exoskeleton, including a first leg 1 and a sealing device 3, a second leg 2 is rotatably mounted on the upper surface of the first leg 1, and the sealing device 3 is disposed on the surface of the second leg 2.

[0022] In this embodiment: the sealing device 3 includes a fixing plate 32, which is fixedly connected to the second leg 2. A rubber sleeve 31 is fixedly connected to the lower surface of the fixing plate 32. The rubber sleeve 31 is fitted onto the pivot of the second leg 2 and the first leg 1. An iron plate 33 is fixedly connected to the lower surface of the rubber sleeve 31. A magnetic suction plate 34 is fixedly connected to the upper surface of the first leg 1. A fixing rod 35 is fixedly connected to the upper surface of the magnetic suction plate 34. A hole is opened on the surface of the iron plate 33. The fixing rod 35 is inserted into the hole on the surface of the iron plate 33. A recycling component 39 is provided on the surface of the iron plate 33. By setting the sealing device 3, the iron plate 33 is attracted and fixed by the magnetic suction plate 34, and further stabilized by the threaded rod 38, so that the sealing sleeve can be tightly fitted onto the pivot of the first leg 1 and the second leg 2. This structure forms a reliable sealing space, which greatly reduces the entry of water vapor into the joint, prevents electronic components from being damaged by short circuit due to water vapor, reduces the rust and corrosion of mechanical parts due to water vapor, thereby extending the service life of the exoskeleton joint and ensuring its stable operation.

[0023] Specifically, the magnetic plate 34 is magnetically connected to the iron plate 33. The upper surface of the magnetic plate 34 is fixedly connected to the mounting bracket 36. By setting the magnetic plate 34, when the iron plate 33 is pulled, the magnetic plate 34 can attract the iron plate 33, so that the iron plate 33 is initially fixed in the initial position, which facilitates subsequent operations, such as rotating the rocker arm 37, the threaded rod 38, etc. to further fix the iron plate 33.

[0024] Specifically, a rocker arm 37 is rotatably connected to the upper surface of the mounting bracket 36. The surface of the rocker arm 37 has a threaded hole. By setting the rocker arm 37, when the iron plate 33 is pulled and attracted to the magnetic plate 34, and the fixing rod 35 is inserted into the iron plate 33, the rocker arm 37 is rotated to move it above the iron plate 33. This action achieves precise positioning of the iron plate 33 by the rocker arm 37, creating conditions for the subsequent rotation of the threaded rod 38 to clamp and fix the iron plate 33 and the magnetic plate 34. The rocker arm 37 is like a positioning rod, ensuring that the threaded rod 38 can accurately abut against the iron plate 33, thereby stably fixing the iron plate 33 on the magnetic plate 34. This ensures that the sealing sleeve can be accurately fitted at the pivot of the first leg 1 and the second leg 2, achieving a reliable seal and preventing moisture from entering.

[0025] Specifically, the surface of the rocker arm 37 is threaded with a threaded rod 38, which abuts against the iron plate 33. By setting the threaded rod 38, rotating the threaded rod 38 to abut against the iron plate 33 can clamp and fix the iron plate 33 and the magnetic plate 34, thereby sealing the pivot of the first leg 1 and the second leg 2 with a sealing sleeve, effectively reducing the entry of moisture and playing a role in sealing and protecting the joint.

[0026] Specifically, there are two threaded rods 38, which are arranged symmetrically.

[0027] Specifically, the recycling component 39 includes a rope 392, with a ring 391 fixedly connected to one side of the rope 392.

[0028] In this embodiment: by setting up the recycling component 39, when it is necessary to inspect and maintain the joint, rotating the threaded rod 38 separates the iron plate 33 from the magnetic plate 34, which can easily release the sealing device 3. By pulling the rubber sleeve 31 upward and using the ring 391 to fit on the hanging rod 393, the rubber sleeve 31 can be quickly retracted, making the joint fully exposed. This facilitates maintenance personnel to carry out comprehensive inspection, cleaning, and replacement of parts, greatly improving maintenance efficiency.

[0029] Specifically, a hanging rod 393 is fixedly connected to the upper surface of the fixing plate 32, and a ring 391 is sleeved with the hanging ring.

[0030] In this embodiment: by setting the ring 391, the rubber sleeve 31 can be easily and quickly retracted when inspecting and maintaining the joint. The rubber sleeve 31 is retracted and put on the hanging rod 393, which reduces the obstruction of operation by the rubber sleeve 31 during maintenance.

[0031] Working principle: By setting up the sealing device 3, when in use, the iron plate 33 is pulled to attract the magnetic plate 34, and at the same time the fixing rod 35 is inserted into the iron plate 33. Then, the rocker arm 37 is rotated until it reaches above the iron plate 33. Then, the threaded rod 38 is rotated, and the threaded rod 38 abuts against the iron plate 33, clamping and fixing the iron plate 33 and the magnetic plate 34. At this time, the sealing sleeve seals the pivot of the first leg 1 and the second leg 2, reducing the entry of water vapor. By setting up the sealing device 3, the iron plate 33 is attracted and fixed by the magnetic plate 34, and further stabilized by the threaded rod 38, so that the sealing sleeve can be tightly fitted at the pivot of the first leg 1 and the second leg 2. This structure forms a reliable sealing space, greatly reducing the entry of water vapor into the joint, preventing electronic components from being damaged by short circuits due to water vapor, reducing the rust and corrosion of mechanical parts due to water vapor, thereby extending the service life of the exoskeleton joint and ensuring its stable operation.

[0032] By setting up the recycling component 39, when it is necessary to inspect and maintain the joint between the first leg 1 and the second leg 2, the threaded rod 38 is rotated to disengage the iron plate 33. At this time, the iron plate 33 is pulled apart from the magnetic plate 34. Then, the rubber sleeve 31 is pulled upwards, and the ring 391 is placed on the hanging rod 393, so that the rubber sleeve 31 can be retracted. By setting up the recycling component 39, when it is necessary to inspect and maintain the joint, the threaded rod 38 is rotated to separate the iron plate 33 from the magnetic plate 34, so that the sealing device 3 can be easily released. By pulling the rubber sleeve 31 upwards and using the ring 391 to place it on the hanging rod 393, the rubber sleeve 31 can be quickly retracted, so that the joint is fully exposed. This makes it convenient for maintenance personnel to carry out comprehensive inspection, cleaning, and replacement of parts, greatly improving maintenance efficiency.
