[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] See also Figures 1 to 7 , shown is an intelligent weight-reducing electric shifting machine in an embodiment of the utility model, including an equipment frame 10, the equipment frame 10 includes a backrest component 20, and an armrest 30 installed on the backrest component 20, the backrest component 20 is provided with a first rotating shaft 40 on a side away from the armrest 30, a storage box 41 is connected to the first rotating shaft 40, a handle is rotatably connected to the armrest 30, a conical toothed disc 33 is fixedly connected to the handle, a second rotating shaft 35 is provided parallel to the handle, a conical gear 36 is fixedly connected to the outer cylindrical surface of the second rotating shaft 35, the conical toothed disc 33 and the conical gear 36 are meshed and connected, and the first rotating shaft 40 and the The second rotating shafts 35 are connected through a synchronous mechanism. A buckle 45 is provided at the bottom of the storage box 41. The buckle 45 is elastically connected to the bottom of the storage box 41 and is connected through a compression spring 46 in this embodiment. The side of the buckle 45 close to the armrest 30 is a wedge-shaped surface. A slot 51 corresponding to the buckle 45 is provided on the armrest 30. The buckle 45 is inserted into the slot 51 to fix the storage box 41. A top block 53 is provided in the slot 51. A lifting assembly for driving the top block 53 to rise and fall in the slot 51 is provided near the slot 51. The lifting assembly drives the top block 53 to rise to disengage the buckle 45 from the slot 51.

[0030] It should be noted that, since the backrest component 20 and the armrest 30 are fixed together, the relative position between the two will not change no matter how the intelligent weight-reducing electric lift changes. Therefore, the utility model arranges the storage box 41 and the corresponding mechanical structure here.

[0031] It can be understood that by providing a first rotating shaft 40 on a side of the backrest component 20 away from the armrest 30, and connecting a storage box 41 to the first rotating shaft 40, a rehabilitation trainer can put food, tools, etc. into the storage box 41 in advance, and the patient can rotate the handle to rotate outward, drive the conical gear plate 33 to rotate, and rotate the storage box 41 to the front of the patient through the conical gear 36, the second rotating shaft 35 and the synchronization mechanism, so that it is convenient to take items. After taking the items, the storage box 41 can be moved out by rotating the handle in the opposite direction. The storage box 41 is moved to be close to the rear of the backrest component 20, which makes rational use of the space. At the same time, a buckle 45 is provided under the storage box 41, and a slot 51 corresponding to the buckle 45 is provided on the armrest 30. Since the buckle 45 is elastically connected to the bottom of the storage box 41, when the storage box 41 moves to the armrest 30, the buckle 45 below it will shrink until the storage box 41 drives the buckle 45 to move into the slot 51, and the buckle 45 rebounds and is inserted into the slot 51 to fix the storage box 41 to prevent the storage box 41 from shaking when the intelligent weight-loss electric shifting machine moves.

[0032] Specifically, the backrest component 20 includes two backrest brackets 22 arranged opposite to each other, and a cushion 21 fixedly connected between the two backrest brackets 22, and the armrest 30 is fixedly connected to the backrest bracket 22; the backrest bracket 22 is provided with two bearing rods 43 arranged opposite to each other, and the first rotating shaft 40 is rotatably connected between the two bearing rods 43.

[0033] It can be understood that in this embodiment, there are two groups of bearing rods 43, a total of four, which are located two by two on one of the backrest brackets 22, and the bearing rods 43 are slightly inclined relative to the armrest 30 to free up rotation space for the storage box 41. Two storage boxes 41 are provided, and each storage box 41 is individually controlled by the left armrest 30 or the right armrest 30.

[0034] More specifically, the handle includes a grip portion 31 located above the armrest 30 , and a handle shaft portion 32 passing through the armrest 30 , the handle shaft portion 32 being rotatably connected to the armrest 30 via a first bearing 34 ; the second rotating shaft 35 is connected to the armrest 30 via a second bearing 39 .

[0035] It is understandable that when a rehabilitation trainer is taking care of a patient, the handle portion 31 will block him / her. Therefore, the structure is preferably designed so that when the handle portion 31 is rotated outward, the storage box 41 rotates in front of the patient, and the rehabilitation trainer will not be blocked by the handle portion 31 when taking care of the patient.

[0036] Furthermore, in this embodiment, the synchronization mechanism includes a worm 37 located on the second rotating shaft 35 and a worm wheel 38 located on the first rotating shaft 40 , and the worm 37 is meshingly connected with the worm wheel 38 .

[0037] It can be understood that in the present embodiment, the stroke of each mechanical structure is set so that the handle portion 31 rotates 90°, so that the first rotating shaft 40 rotates 270°. Therefore, it is necessary to increase the transmission ratio by means of a bevel gear 33 and a bevel gear 36, and based on the rotation of the second rotating shaft 35, the worm 37 drives the worm wheel 38 to rotate, thereby improving the transmission efficiency. Due to the self-locking property of the worm 37 and the worm wheel 38 structure, the worm wheel 38 can only be driven to rotate by the rotation of the worm 37, so that the first rotating shaft 40 will not shake due to external force, and the stability is stronger.

[0038] It should be noted that in other embodiments, a gear plus chain structure (noise is high) or a gear rack structure (space is large) may also be used, which are all within the purview of those skilled in the art.

[0039] Furthermore, in the present embodiment, the lifting assembly includes an unlocking block 52 slidably connected to the armrest 30, and an elastic member 54 located on a side of the unlocking block 52 close to the lifting block 53. The unlocking block 52 is wedge-shaped above a side close to the lifting block 53. The unlocking block 52 is pressed to cause the lifting block 53 to rise along the wedge-shaped surface of the unlocking block 52.

[0040] It can be understood that since the present embodiment adopts a worm gear transmission form between the first rotating shaft 40 and the second rotating shaft 35, this form has a self-locking property and the worm wheel 38 can only be driven to rotate by the worm 37. Therefore, it can be ensured that the rotation of the first rotating shaft 40 is driven only by the rotation of the second rotating shaft 35, and the storage box 41 on the first rotating shaft 40 will not shake. However, it is still necessary to use a slot 51 to locate the optimal position of the storage box 41. When the buckle 45 on the storage box 41 is inserted into the slot 51 on the armrest, it is the optimal position. When the buckle 45 needs to be unlocked, the unlocking block 52 can be pressed to move the unlocking block 52 toward the top block 53. The wedge-shaped surface of the unlocking block 52 will lift the top block 53, and the lifting of the top block 53 will lift the buckle 45, so that the compression spring 46 is compressed until the buckle 45 is disengaged from the slot 51. The patient can turn the handle by himself to return the storage box 41 to the back of the cushion 21. After the unlocking block 52 is released, the elastic member 54 rebounds to reset the unlocking block 52 and the top block 53 falls down again. This design structure is convenient for the patient to unlock the fixation of the storage box 41 by himself.

[0041] It should be noted that, in other embodiments, the lifting assembly may also use other structures such as the seat belt buckle 45, which are also conceivable by those skilled in the art.

[0042] Preferably, a torsion spring 44 is sleeved between the bearing rod 43 and the rotating shaft, and when the storage box 41 is located behind the cushion 21, the torsion spring 44 is in a reset state.

[0043] It can be understood that when the storage box 41 needs to be reset to the back of the cushion 21, one hand uses the unlocking block 52 to lift the buckle 45, and the other hand rotates the handle in the opposite direction, and the conical gear plate 33, the conical gear 36, the second rotating shaft 35, and the first rotating shaft 40 are slowly reset in sequence until the storage box 41 is against the back of the cushion 21. At this time, the handle is also perpendicular to the armrest 30. Due to the presence of the torsion spring 44, whether the storage box 41 is rotated in front of the patient or behind the cushion 21, it can ensure that the structure has a certain damping sense, thereby avoiding the structure operating too smoothly, resulting in excessive instantaneous impact force, causing the contents of the storage box 41 to spill out.

[0044] Furthermore, the storage box 41 has a plurality of storage compartments 42 therein.

[0045] In summary, the intelligent weight-reducing electric shifting machine in the above-mentioned embodiments of the utility model is provided with a first rotating shaft on the side of the backrest component away from the armrest, and a storage box is connected to the first rotating shaft. The rehabilitation trainer can put food, tools, etc. into the storage box in advance, and the patient himself can turn the handle to make the handle rotate outward, drive the conical gear disk to rotate, and rotate the storage box in front of the patient through the conical gear, the second rotating shaft and the synchronization mechanism, so as to facilitate taking items. After taking the items, the storage box can be moved to be close to the back of the backrest component by rotating the handle in the opposite direction, thereby reasonably utilizing the space. At the same time, a buckle is provided at the bottom of the storage box, and a slot corresponding to the buckle is provided on the armrest. Since the buckle is elastically connected to the bottom of the storage box, when the storage box moves to the armrest, the buckle below it will shrink until the storage box drives the buckle to move into the slot, and the buckle rebounds and is inserted into the slot to fix the storage box, thereby preventing the storage box from shaking when the intelligent weight-reducing electric shifting machine moves.
