Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, specifically a multifunctional exercise device. Background Technology

[0002] Malignant tumors seriously affect human health, and the occurrence of sarcopenia increases the difficulty of treatment for patients with malignant tumors. In order to cope with sarcopenia, physical exercises that can produce skeletal muscle contraction can be carried out, such as resistance training using rehabilitation exercise equipment, to effectively improve muscle strength, quality and physical function in patients with sarcopenia.

[0003] In existing technologies, such as the exercise rehabilitation device entitled "A Exercise Rehabilitation Device for Sarcopenia in the Elderly" (Document No. CN221358388U), a base, a column mounted on the base, a leg support frame, a connector, a rotating sleeve, and a bidirectional damper are included. The leg support frame is fixedly connected to the connector, the connector is hinged to the rotating sleeve, the rotating sleeve is fitted onto the column, and the bidirectional damper is ball-jointed to one end of the connector. The leg support frame can rotate both horizontally and vertically, and can be used for hip adduction and abduction training as well as quadriceps resistance training. However, the implementation of this solution first requires the patient to sit on the device's cushion, which is unsuitable for patients who are bedridden for extended periods. Furthermore, the leg support frame lacks adjustment, making it unsuitable for patients of different heights and leg lengths. Secondly, the device only supports lower limb (hip adduction and abduction, quadriceps) resistance training, lacking upper limb rehabilitation functions, resulting in limited functional coverage and failing to meet the needs of whole-body rehabilitation. Summary of the Invention

[0004] This invention provides a multifunctional exercise device to solve the problem that existing rehabilitation devices have limited functions and cannot be adapted to bedridden users.

[0005] The present invention provides the following technical solution: a multifunctional exercise device, including a fixed plate connected to the end of a bed, a pin is rotatably arranged on the front side of the fixed plate, the pin is horizontally arranged and the plane of rotation of the pin is perpendicular to the front side of the fixed plate, the two ends of the pin are connected to a training plate, and the front side of the training plate is provided with a lower limb exercise piece for exercising the lower limbs and an upper limb exercise piece for exercising the upper limbs.

[0006] As a further technical solution of the present invention, an adjustment mechanism for adjusting the tilt angle of the training board is provided on the lower plate surface of the fixed plate, and the adjustment mechanism is located below the pin shaft. The adjustment mechanism includes a lead screw rotatably mounted on the fixed plate, and the lead screw is perpendicular to the plate surface.

[0007] As a further technical solution of the present invention, two lead screws are provided. A power input shaft parallel to the core of the lead screw is rotatably provided on the fixed plate. The two lead screws are symmetrically arranged on the left and right sides of the power input shaft. A lead screw nut sleeve is threadedly connected to one end of the lead screw near the training plate, and a driven gear is connected to the other end. The two lead screw nut sleeves are connected by a connecting plate. A drive gear is connected to the end of the power input shaft away from the training plate. The drive gear meshes with the two driven gears respectively.

[0008] As a further technical solution of the present invention, the training board includes an upper plate and a lower plate. The upper plate is convex and the lower plate is concave. The convex part of the upper plate and the concave part of the lower plate are in a sliding fit. A guide rod is fixed on the lower side of the upper plate and a guide hole for guiding the guide rod is opened on the upper side of the lower plate.

[0009] As a further technical solution of the present invention, the rear side plate of the training plate is provided with a groove, and the groove is connected to the guide hole. The bottom end of the guide rod is located in the groove, and a limiting ring is fixed at the bottom end of the guide rod. The end of the power input shaft is inserted into the limiting ring. The inner diameter of the limiting ring is larger than the diameter of the power input shaft, and the core of the limiting ring is coplanar with the core of the power input shaft.

[0010] As a further technical solution of the present invention, the lower limb exercise device includes two foot pedal buttons on the upper plate and two foot pedal buttons on the lower plate, and the two foot pedal buttons on the upper plate and the two foot pedal buttons on the lower plate are arranged symmetrically. The training plate has mounting holes for embedding the foot pedal buttons. The side of the foot pedal button outside the mounting hole is a hemispherical surface. A compression spring is connected between the foot pedal button and the bottom of the mounting hole. The compression spring provides elastic force to drive the foot pedal button to move away from the bottom of the mounting hole.

[0011] As a further technical solution of the present invention, the upper limb exercise device includes two pull rings disposed on the upper part of the front side panel of the training board and two pull rings disposed on the lower part of the front side panel of the training board. The training board has a cavity for accommodating tension springs. One end of each pull ring is connected to a corresponding tension spring, and the tension spring provides elastic force to drive the pull ring to move towards the training board.

[0012] As a further technical solution of the present invention, both the bottom of the mounting hole and the bottom of the cavity are provided with touch sensing heads, and the end of the tension spring located at the bottom of the cavity and the end of the compression spring located at the bottom of the hole are in contact with the corresponding touch sensing heads.

[0013] As a further technical solution of the present invention, a display screen is installed on the top of the fixed plate, and the display screen is connected to the touch sensor head on the training plate by a wire; the two ends of the pin are connected to the fixed plate by bearing seats, and a connecting block is fixed on the rear side of the upper plate, and the connecting block is fixedly connected to the two ends of the pin.

[0014] As a further technical solution of the present invention, a housing is fixed to the rear side of the fixing plate, and the driving gear and the driven gear are both located inside the housing. A motor for driving the power input shaft to rotate is installed on the housing.

[0015] The present invention has the following beneficial effects:

[0016] 1. In this invention, the exercise device installed on the footboard of the bed is convenient for users to operate and train while lying flat on the hospital bed. The training board is connected to the fixed plate through a pin, so that the training board can rotate around the pin, thereby realizing the adjustment of the tilt of the training board to meet the user's exercise needs. When using the above-mentioned exercise device for resistance training, the lower limb exercise component can perform resistance training on the lower limbs, and the upper limb exercise component can perform resistance exercise by pulling elastic bands on the upper limbs.

[0017] 2. In this invention, the end of the power input shaft near the training board is continuously inserted into the limiting ring. When the training board is tilted, the lower board automatically moves downward under the action of gravity, avoiding the problem that the distance between the bottom of the training board and the bed board plane increases after the training board swings upward, which would cause inconvenience to the user. Moreover, the end of the power input shaft is always in the state of supporting the limiting ring, so that when the tilt angle of the training board is adjusted, the lower board will not continue to move downward. On the one hand, this can ensure the stability of the training board during use, and on the other hand, it can prevent the lower board from separating from the upper board and falling to the ground when the exercise device is moved. Furthermore, tilting the training board at the appropriate angle can meet the training needs of different users. Attached Figure Description

[0027] The technical solutions of the embodiments of this specification will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of this specification and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this specification.

[0028] In the description of this application, terms such as "front," "rear," "inner," "outer," "upper," "lower," "left," and "right" are used only to indicate orientation or positional relationship for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this specification.

[0029] For ease of description, the terms front, back, left, and right are defined according to the state of the exercise device after it is installed on the footboard A of the bed, as follows: Figure 1 As shown, the side of the training board 30 facing the user is defined as the front side, the side away from the user is defined as the back side, the user's left side is defined as the left side when the training board 30 faces the user, and the user's right side is defined as the right side.

[0030] Please see Figure 1-9As shown, a multifunctional exercise device includes a fixed plate 10 connected to a bed end plate A. A pin 20 is rotatably mounted on the front side of the fixed plate 10. The pin 20 is horizontally arranged and its rotation plane is perpendicular to the front side of the fixed plate 10. Both ends of the pin 20 are connected to a training plate 30. The front side of the training plate 30 is provided with a lower limb exercise component 40 for exercising the lower limbs and an upper limb exercise component 50 for exercising the upper limbs.

[0031] In the above scheme, the footboard A refers to the tail of the hospital bed, that is, the side corresponding to the patient's feet. The multifunctional exercise device involved in this invention is installed at this position. Specifically, the upper part of the fixing plate 10 has a U-shaped structure, and the opening of the U-shaped structure faces downward. It can be understood that the top of the fixing plate 10 is connected to the vertical plate 12 through the strip plate 11, and the vertical plate 12 is parallel to the surface of the fixing plate 10. An adjusting bolt 13 is installed on the vertical plate 12. When installing the fixing plate 10, the fixing plate 10 is first hung on the footboard A through the U-shaped structure, and then the adjusting bolt 13 is rotated so that the bolt tail of the adjusting bolt 13 abuts against the footboard A, so that the fixing plate 10 is stably installed on the footboard A. The exercise device installed on the footboard A of the bed allows users to perform training while lying flat on the hospital bed. The training board 30 is connected to the fixed plate 10 via a pin 20, allowing the training board 30 to rotate around the pin 20. This enables adjustment of the tilt of the training board 30 to suit the user's training needs. When using the exercise device for resistance training, the lower limb exercise component 40 can provide resistance training for the lower limbs, while the upper limb exercise component 50 can provide resistance training for the upper limbs by pulling elastic bands.

[0032] like Figure 3 , 4 As shown in Figure 5, in order to facilitate the adjustment of the tilt angle of the training board 30, an adjustment mechanism for adjusting the tilt angle of the training board 30 is provided on the lower plate surface of the fixed plate 10, and the adjustment mechanism is located below the pin 20. The adjustment mechanism includes a lead screw 61 rotatably mounted on the fixed plate 10, and the lead screw 61 is perpendicular to the plate surface of the fixed plate 10. There are two lead screws 61. A power input shaft 62 parallel to the core of the lead screw 61 is also rotatably mounted on the fixed plate 10. The two lead screws 61 are symmetrically arranged on the left and right sides of the power input shaft 62. The end of the lead screw 61 near the training board 30 is threadedly connected to a lead screw nut sleeve 63, and the other end is connected to a driven gear 64. The two lead screw nut sleeves 63 are connected by a connecting plate 66. The end of the power input shaft 62 away from the training board 30 is connected to a driving gear 65, and the driving gear 65 meshes with the two driven gears 64 respectively.

[0033] Specifically, the threads of the two lead screws 61 are in opposite directions, and the lead screws 61 are matched with the corresponding lead screw nut sleeves 63. When adjusting the tilt angle of the training plate 30, the power input shaft 62 can be rotated, which drives the drive gear 65 to rotate. The drive gear 65 meshes with the two driven gears 64, causing the driven gears 64 to drive the lead screws 61 to rotate. After the lead screws 61 rotate, the two lead screw nut sleeves 63 will make linear displacement along the lead screws 61, causing the lead screw nut sleeves 63 to move in the direction of pressing the training plate 30. By pushing the lower part of the training plate 30, the training plate 30 will swing upward as a whole, thereby realizing the adjustment of the tilt angle of the training plate 30 to meet the user's needs.

[0034] Furthermore, such as Figure 6 , 7 As shown, after the training board 30 swings upward, the distance between the bottom of the training board 30 and the bed board surface increases. When the user's lower limbs are laid flat on the hospital bed, the soles of the feet cannot contact the foot pedal button 41 of the lower limb exercise device 40. The user needs to raise both feet to contact the lower limb exercise device 40, which is inconvenient to use. Therefore, the training board 30 includes an upper board 31 and a lower board 32. The upper board 31 is convex and the lower board 32 is concave. The convex part of the upper board 31 and the concave part of the lower board 32 are in a sliding fit. A guide rod 311 is fixed on the lower side of the upper board 31, and a guide hole 321 for guiding the guide rod 311 is opened on the upper side of the lower board 32. Specifically, the lower board 32 can be pushed downward to create a gap between the lower board 32 and the upper board 31, so that the bottom of the lower board 32 is in continuous contact with the bed board surface. During this process, the guide rod 311 slides through the guide hole 321, and the upper board 31 and the lower board 32 will not completely separate.

[0035] like Figure 6 , 7 As shown, to prevent the lower plate 32 from automatically separating from the upper plate 31 under gravity, the rear side of the training plate 30 is provided with a groove 322, which is connected to the guide hole 321. The bottom end of the guide rod 311 is located in the groove 322, and a limiting ring 312 is fixed to the bottom end of the guide rod 311. The end of the power input shaft 62 is inserted into the limiting ring 312. The inner diameter of the limiting ring 312 is larger than the diameter of the power input shaft 62, and the ring core of the limiting ring 312 is coplanar with the shaft core of the power input shaft 62. In specific implementation, the end of the power input shaft 62 near the training plate 30 is continuously inserted into the limiting ring 312. When the training plate 30 is tilted, the lower plate 32 automatically moves downward under gravity, while the end of the power input shaft 62 is always in a state of supporting the limiting ring 312. Therefore, when the tilt angle of the training plate 30 is adjusted, the lower plate 32 will not continue to move downward.

[0036] In the above, such as Figure 8As shown, the lower limb exercise device 40 includes two foot pedal buttons 41 on the upper plate 31 and two foot pedal buttons 41 on the lower plate 32, with the two foot pedal buttons 41 on the upper plate 31 and the two foot pedal buttons 41 on the lower plate 32 arranged symmetrically. The training plate 30 has mounting holes 33 for the foot pedal buttons 41 to be inserted. The side of the foot pedal button 41 outside the mounting hole 33 is a hemispherical surface. A compression spring 42 connects the foot pedal button 41 to the bottom of the mounting hole 33. The compression spring 42 provides elastic force to drive the foot pedal button 41 to move away from the bottom of the mounting hole 33. When the patient's feet squeeze the foot pedal buttons 41, the foot pedal buttons 41 move in the direction of entering the mounting hole 33, causing the compression spring 42 to compress and deform. The compression spring 42 also generates elastic force in the opposite direction of the squeezing, driving the feet to move away from the bottom of the mounting hole 33, thus completing one lower limb resistance training. The foot pedal button 41 is used to realize "ankle pump exercise", which is the core movement of lower limb resistance rehabilitation. It requires the ankle joint to flex and extend to drive the calf muscle contraction. The arc of the hemispherical surface can guide the patient to naturally complete the complete movement of "toe down (plantar flexion) and toe up (dorsiflexion)" when stepping, avoiding the problem of only local force exertion on the sole of the foot due to unreasonable button shape, or even the deformation of movement, ensuring that the exercise can accurately act on the calf muscle group, which meets the requirements of sarcopenia rehabilitation.

[0037] In the above, such as Figure 9 As shown, the upper limb exercise device 50 includes two pull rings 51 disposed on the upper part of the front side panel of the training board 30 and two pull rings 51 disposed on the lower part of the front side panel of the training board 30. The training board 30 has a cavity 34 for accommodating tension springs 52. One end of each pull ring 51 is connected to the corresponding tension spring 52. The tension spring 52 provides elastic force to drive the pull ring 51 to move towards the training board 30. When the patient holds the pull ring 51 and moves the pull ring 51 away from the training board 30, the tension spring 52 is stretched and deformed, and provides elastic force to drive the pull ring 51 to move towards the training board 30, thereby completing the resistance training of the upper limb.

[0038] Furthermore, such as Figure 8 , 9 As shown, both the bottom of the mounting hole 33 and the bottom of the cavity 34 are provided with touch sensor heads 35. The end of the tension spring 52 located at the bottom of the cavity and the end of the compression spring 42 located at the bottom of the hole are in contact with the corresponding touch sensor head 35. The touch sensor head 35 mainly collects the pressure changes at the compression spring 42 and the tension spring 52 to determine whether the corresponding resistance training has been carried out.

[0039] like Figure 1-5As shown, to enhance the enjoyment, a display screen 70 is mounted on the top of the fixed plate 10. The display screen 70 is connected to the touch sensor 35 on the training plate 30 via a wire. The display screen 70 is located above the fixed plate 10 for easy viewing by the user. The display screen 70 has a built-in AI chip and corresponding operating system. The display screen 70 has settings options, allowing users to set the duration of each exercise program and play music, riddles, videos, and other fun activities. The volume is adjustable, allowing patients to enjoy entertainment while exercising. After each set exercise is completed, a voice prompt will say, "Congratulations on completing today's XX exercise program. Please continue with the next exercise." After all exercises for the day are completed, a voice prompt will say, "Congratulations on completing all today's exercises. We applaud you and look forward to seeing you again next time!"

[0040] like Figure 5 As shown, the specific installation structure of the pin 20 is as follows: the two ends of the pin 20 are connected to the fixed plate 10 through the bearing seat 21, and the rear side plate of the upper plate 31 is fixed with a connecting block 22, which is fixedly connected to the two ends of the pin 20.

[0041] like Figure 3 , 4 As shown, in order to avoid damage to the driving gear 65 and driven gear 64 by the external environment, a housing 67 is fixed to the rear side of the fixing plate 10. The driving gear 65 and driven gear 64 are both located inside the housing 67. A motor 68 for driving the power input shaft 62 to rotate is installed on the housing 67.

[0042] The embodiments described above are merely preferred embodiments of this specification and are not intended to limit the scope of this specification. Any modifications and improvements made by those skilled in the art to the technical solutions of this specification without departing from the spirit of this specification should fall within the protection scope defined by the claims of this specification.
