[0002] Rehabilitation equipment, such as rehabilitation therapy robots, are intelligent devices that integrate multiple advanced technologies to assist or replace traditional rehabilitation therapy methods. Classified by function, they can be divided into sports rehabilitation and physical therapy. Sports rehabilitation includes upper limb rehabilitation robots and lower limb exoskeleton rehabilitation robots. Upper limb rehabilitation robots help individuals with upper limb dysfunction perform grasping and extension exercises; lower limb exoskeleton rehabilitation robots assist patients with lower limb dysfunction in standing and walking. Physical therapy includes shockwave therapy robots, radiofrequency thermotherapy robots, and moxibustion robots. Shockwave therapy robots use sound wave energy to break up blockages and nodules; radiofrequency thermotherapy robots use radiofrequency technology to raise the temperature of human tissue and activate white blood cells; moxibustion robots can replicate traditional moxibustion techniques. During treatment, rehabilitation equipment can operate in lying, sitting, or semi-reclining positions. However, because the handrails of traditional rehabilitation equipment are fixed to the main body, they move with the equipment when it is in different positions, making them difficult for users to grip and causing discomfort.

[0037] This utility model provides a backrest armrest structure 100, suitable for rehabilitation equipment. For details, please refer to... Figures 1 to 2In this embodiment, the backrest armrest structure 100 includes a base 1, a backrest support 2, and an armrest assembly 3; one end of the backrest support 2 is rotatably connected to the base 1; the armrest assembly 3 includes an armrest component disposed on the backrest support 2, an armrest mounting component 31 connected to the armrest component, and an adjustment structure 32 connecting the armrest mounting component 31 and the base 1; when the backrest support 2 rotates relative to the base 1, the adjustment structure 32 can drive the armrest mounting component 31 to rotate, so that the armrest component can be kept in a state parallel to the base 1.

[0038] In this embodiment, the base 1 allows the user to sit on it, and the backrest bracket 2 supports the user's back. By rotating the backrest bracket 2 relative to the base 1, the rehabilitation device can be adjusted to a sitting, semi-reclining, or lying position. The armrest assembly 3 includes an armrest component, an armrest mounting component 31, and an adjustment structure 32. The armrest component is for the user to grip and is mounted on the backrest bracket 2 via the armrest mounting component 31. When the backrest bracket 2 rotates relative to the base 1, the adjustment structure 32 drives the armrest mounting component 31 to rotate, keeping the armrest component parallel to the base 1. This ensures that the armrest component remains in a comfortable gripping position, allowing the user to comfortably support their arm in any posture.

[0039] The base 1 can be configured as a flat plate, a seat, a bracket, or a box structure. Preferably, the base 1 can be configured as a seat structure for rehabilitation equipment. When the rehabilitation equipment is in normal use, the user can sit on the base 1 with their back against the backrest support 2 and their hands can hold the armrests. By adjusting the rotation of the backrest support 2, the backrest armrest structure 100 can be in different working postures.

[0040] The armrest is generally flat and extends laterally along the base 1. Specifically, when a user sits on the base 1, the armrest extends in the left-right direction relative to the user. The backrest support 2 extends longitudinally and is rotatable relative to the base 1 about a laterally extending axis.

[0041] The adjustment structure 32 can be used to adjust the state of the armrest mounting member 31, so that the armrest member can always remain parallel to the base 1. After the backrest bracket 2 is rotated, the surface of the armrest member remains parallel to the sitting surface of the base 1, making it easier for the user to hold.

[0042] Preferably, combined with Figure 2 and Figure 3As shown, the adjustment structure 32 includes a first mounting head 321, a first connecting rod 322, a second connecting rod 323, and a second mounting head 325. The first mounting head 321 is disposed on the base 1. One end of the first connecting rod 322 is rotatably connected to the first mounting head 321. The second connecting rod 323 is coaxially arranged with the first connecting rod 322, and one end is movably connected to the first connecting rod 322. The second mounting head 325 is disposed on the armrest mounting member 31 and is rotatably connected to the other end of the second connecting rod 323. The first connecting rod 322 and the second connecting rod 323 can slide relative to each other. When the backrest bracket 2 rotates relative to the base 1, the first connecting rod 322 and the second connecting rod 323 can adjust the connection length between the first mounting head 321 and the second mounting head 325 to drive the armrest mounting member 31 to rotate. When the backrest support 2 and the base 1 are at different rotation angles, the relative positions of the first connecting rod 322 and the second connecting rod 323 are adjusted so that the armrest mounting member 31 can rotate relative to the backrest support 2. When the backrest support 2 rotates from a sitting position to a lying position, the backrest support 2 rotates by a certain angle. Then, under the action of the first connecting rod 322 and the second connecting rod 323, the armrest mounting member 31 is driven to rotate in the opposite direction relative to the backrest support 2 by a certain angle, so that the armrest member can be kept parallel to the base 1.

[0043] It is understood that there are many ways to adjust the relative position of the first link 322 and the second link 323. In one embodiment, the first link 322 and the second link 323 can be slidably connected relative to each other. For example, a slide rail is provided on the first link 322, and a pulley is provided on the second link 323. The pulley is slidably engaged with the slide rail, so that the second link 323 can slide relative to the first link 322.

[0044] Preferably, in another embodiment, one end of the first connecting rod 322 and the second connecting rod 323 connected is provided with a sleeve 324, and the other is movably sleeved within the sleeve 324 so as to be movable relative to the sleeve 324. Taking the sleeve 324 being provided on the second connecting rod as an example, the first connecting rod 322 has a first end connected to the base 1 and a second end connected to the second connecting rod 323. The second connecting rod 323 has a first end connected to the backrest bracket 2 and a second end connected to the first connecting rod 322. The sleeve 324 is provided at the second end of the second connecting rod 323, and the second end of the first connecting rod 322 is slidably sleeved within the sleeve 324. By extending or extending the first connecting rod 322 into or out of the sleeve 324, the length of the first connecting rod 322 and the second connecting rod 323 connected between the base 1 and the backrest bracket 2 can be adjusted to better drive the armrest mounting member 31 to rotate.

[0045] Among them, combined Figure 2 and Figure 3 As shown, the first mounting head 321 includes two first mounting arms 3211 arranged opposite to each other. One end of each first mounting arm 3211 is fixed to the base 1, and the other end is suspended. Preferably, the two first mounting arms 3211 are integrally formed with the base 1 for a more stable connection. The two first mounting arms 3211 are provided with first connecting holes arranged opposite to each other, and the first connecting rod 322 is provided with a first mating hole. The adjustment structure 32 also includes a first connecting shaft, which passes through the two first connecting holes and the first mating hole to rotatably connect the first mounting head 321 and the first connecting rod 322. On the one hand, the two first mounting arms 3211 limit the movement of the first connecting rod 322 on both sides, making it less prone to wobbling or shifting when rotating relative to the base 1; on the other hand, it allows for a larger rotation range of the first connecting rod 322, better adapting to the rotation stroke of the backrest bracket 2.

[0046] The second mounting head 325 is configured similarly to the first mounting head 321. Preferably, it is combined with... Figure 2 and Figure 3As shown, the second mounting head 325 includes two opposing second mounting arms 3251, one end of which is fixed to the handrail mounting member 31, and the other end is suspended. Preferably, the two second mounting arms 3251 are integrally formed with the handrail mounting member 31, resulting in a more stable connection and easier assembly. The two second mounting arms 3251 are provided with opposing second connecting holes, and the second connecting rod 323 is provided with a second mating hole. The adjustment structure 32 also includes a second connecting shaft, which passes through the two second connecting holes and the second mating hole to rotatably connect the second mounting head 325 and the second connecting rod 323. This also makes the second connecting rod 323 less prone to wobbling during rotation, while also allowing for a larger rotational stroke.

[0047] Specifically, the armrest mounting component 31 includes an armrest mounting rod 311 and a first connector 312 and a second connector 313 respectively disposed at both ends of the armrest mounting rod 311. The armrest mounting rod 311 is rotatably sleeved on the backrest bracket 2 and is perpendicular to the first connecting rod 322 and / or the second connecting rod 323. The first connector 312 and the second connector 313 are respectively connected to the armrest component. The armrest mounting rod 311 is disposed on the back of the backrest bracket 2. The side of the backrest bracket 2 that supports the back of the human body is the front, and the side facing away from the human body is the back. Multiple rings are provided on the back of the backrest bracket 2, and the multiple rings are arranged coaxially and spaced apart in the transverse direction. The armrest mounting rod 311 is rotatably sleeved in the multiple rings, and both ends can extend from the transverse ends of the backrest bracket 2, so that the first connector 312 and the second connector 313 can be better connected to the armrest component. The handrail mounting rod 311 is integrally formed with the two second mounting arms 3251. The two second mounting arms 3251 are rotatably connected to the second connecting rod 323. The second connecting rod 323 moves relative to the first connecting rod 322 to push the handrail mounting rod 311 to rotate, thereby adjusting the position of the handrail component.

[0048] Furthermore, both the first connector 312 and the second connector 313 are provided with mounting portions 314, and the handrail component is provided with a mating portion. The mounting portion 314 and the mating portion are anti-rotationally mated to fix the handrail component to the handrail mounting component 31. Thus, when the handrail mounting rod 311 rotates, it can better drive the handrail component to rotate, so as to maintain the position of the handrail component parallel to the base 1.

[0049] Preferably, such as Figure 3As shown, each of the mounting portions 314 includes a limiting hole 3141 provided on the first connector 312 or the second connector 313, and the limiting hole 3141 is non-circular. The mating portion includes a limiting protrusion provided on the handrail component, and the limiting protrusion is inserted into the corresponding limiting hole 3141, thereby connecting the handrail mounting rod 311 and the handrail component, so that the handrail mounting rod 311 and the handrail component will not rotate relative to each other. Specifically, the limiting hole 3141 has a circular hole segment communicating with the handrail mounting rod 311, and a square segment provided on one side of the circular hole segment, and the square segment is communicating with the circular hole segment. This makes alignment easier during the installation of the handrail component, and makes assembly more convenient.

[0050] This utility model also provides a rehabilitation device, including a device body and the aforementioned backrest and armrest structure 100. The device body may include a hip support and / or a leg support. The base 1 of the backrest and armrest structure 100 may be formed on the hip support. When the rehabilitation device is working, the backrest support 2 may rotate relative to the hip support, so that the armrest can remain parallel to the hip support. Thus, when the rehabilitation device is in any working posture, the user's hands can comfortably support the armrest, resulting in higher comfort.

[0051] The backrest support 2 can be driven to rotate by a drive mechanism located on the back of the backrest support 2 and connected to the base 1. The drive mechanism may include a driver and a telescopic rod connected to the driver. The telescopic rod is connected to the backrest support 2. The driver is configured as an electric cylinder or a pneumatic cylinder. The driver drives the telescopic rod to extend or retract, thereby pushing the backrest support 2 to rotate relative to the base 1, thus more intelligently adjusting the position of the backrest support 2 to regulate the working state of the rehabilitation equipment.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
