[0031] like Figures 1 to 6As shown, this embodiment proposes a rehabilitation massage wheelchair device, including a first housing 1, a pair of side panels 3, pedals 4, rollers 11, armrests 12, and a second housing 2. The pair of side panels 3 are disposed on one side of the first housing 1, and the pedals 4 are respectively mounted on the side panels 3. The rollers 11 are disposed on both sides of the first housing 1, and the armrests 12 and the second housing 2 are both disposed on the upper end of the first housing 1. In this way, the user can sit on the first housing 1 and lean against the second housing 2, and the user's feet can step on the pedals 4 to move the wheelchair by pushing the rollers 11. In addition, a pair of hollow rods 21 are provided between the first housing 1 and the second housing 2, which can connect the first housing 1 and the second housing 2. The surfaces of the first housing 1 and the second housing 2 that contact the user are both made of rubber material for subsequent... For ease of description, the contact surface is referred to simply as the "rubber surface". The second housing 2 is equipped with a massage component 5, which can provide massage treatment to the user. The second housing 2 is also equipped with a miniature air pump 6, a first air tube 61, and a second air tube 62. One end of the first air tube 61 and the second air tube 62 are connected to the miniature air pump 6. The other ends of the first air tube 61 and the second air tube 62 extend into the first housing 1 through each hollow rod 21. The other end of the first air tube 61 and the second air tube 62 is equipped with several airbags 7. Each airbag 7 can be used to press against the user's arm to provide arm massage treatment. In addition, the first air tube 61 and the second air tube 62 are respectively equipped with a first valve body 63 and a second valve body 64, which are respectively engaged with the massage component 5. By using rubber material on the side of the second housing 2 that contacts the user, the massage component 5 can push against the rubber surface of the second housing 2 to massage the user's back, preventing bedsores caused by prolonged back-sitting. The system includes a miniature air pump 6, a first air tube 61, a second air tube 62, an airbag 7, a first valve body 63, and a second valve body 64. The massage component 5 engages with the first and second valve bodies 61 and 62, opening and closing them during the massage process. This allows the airflow through the miniature air pump 6, the first air tube 61, the second air tube 62, and the airbag 7 to be open or closed. When the airbag 7 is inflated, it protrudes and presses against the rubber surface of the first housing 1, contacting the user's buttocks and providing a massage, thus preventing bedsores. The wheelchair device in this application effectively solves the problem of bedsores on the user's back and arms caused by prolonged use of a wheelchair.

[0032] In this application, when the massage component 5 is massaging the back, since the massage component 5 is engaged with the first valve body 63 and the second valve body 64, the massage component 5 can open the first valve body 63 and / or the second valve body 64 during operation, thereby opening the air passage of the micro air pump 6, the first air tube 61, the second air tube 62, and the airbag 7, so that the gas in the micro air pump 6 flows into the airbag 7. When the airbag 7 is inflated, it can bulge against the rubber surface of the first housing 1, thereby achieving massage treatment for the user's arm and reducing the occurrence of bedsores.

[0033] Further, please refer to Figures 4 to 6 As shown, the massage assembly 5 includes a base 51 and multiple mounting seats 52. The base 51 is disposed in the second housing 2. Multiple mounting seats 52 are spaced apart along the circumference of the base 51. A rotating wheel 53 is rotatably mounted on each mounting seat 52. A connecting member 54 is integrally formed on the rotating wheel 53. A connecting rod 55 is provided on the connecting member 54 for transmission. A massage head 56 is provided at the end of the connecting rod 55. A support plate 57 is distributed parallel to one side of the base 51. The support plate 57 is mounted on each connecting member 54. Specifically, the support plate 57 has through holes corresponding to the positions of each connecting member 54, and each connecting member 54 can pass through each through hole. In addition, a turntable 59 is rotatably mounted on the support plate 57, and a lifting wheel assembly 58 that abuts against the turntable 59 is mounted on the connector 54. Furthermore, a gear assembly 8 is also provided in the second housing 2. A first tooth 592 is provided on the outer wall of the turntable 59, and the first tooth 592 meshes with the gear assembly 8. The gear assembly 8 can be used to drive the turntable 59 to rotate. A protrusion 591 is provided on the turntable 59, and the protrusion 591 abuts against the lifting wheel assembly 58, causing the lifting wheel assembly 58 to drive the connecting rod 55 to rise and fall. In addition, bosses 593 are provided on opposite sides of the outer wall of the turntable 59, and a second tooth is provided on the outer wall of the bosses 593. A first rotating gear 65 and a second rotating gear 66 are respectively provided on the first valve body 63 and the second valve body 64, and the second tooth meshes with the first rotating gear 65 and the second rotating gear 66 respectively.

[0034] In this application, the massage principle of the massage component 5 is as follows:

[0035] When a massage is needed on the user's back, the gear assembly 8 meshes with the first tooth 592 of the turntable 59. By driving the gear assembly 8, the turntable 59 rotates, and the protrusion 591 on the turntable 59 rotates synchronously. The protrusion 591 pushes the lifting wheel assembly 58 up and down, and the lifting wheel assembly 58 in turn drives the connecting rod 55 up and down. The connecting rod 55 in turn drives the massage head 56 to push against the rubber surface of the second housing 2, thereby achieving a massage on the user's back.

[0036] Preferably, the turntable 59 and the protrusion 591 are integrally formed. This integral forming reduces subsequent machining and lowers processing costs.

[0037] Preferably, the turntable 59 and the protrusion 591 are detachably connected, specifically, the turntable 59 and the protrusion 591 are connected by a snap-fit ​​connection. This detachable connection allows for easy replacement of the protrusion 591 when it wears out after prolonged use.

[0038] The principle behind massaging the user's arm in this application is as follows:

[0039] As the turntable 59 rotates, the protrusions 593 on opposite sides of the turntable rotate synchronously. The second teeth on the protrusions 593 drive the first rotating gear 65 and the second rotating gear 66 to rotate, thereby realizing the synchronous opening of the first valve body 63 and the second valve body 64. This enables the air passage of the micro air pump 6, the first air tube 61, the second air tube 62, and the airbag 7 to be connected, allowing the gas in the micro air pump 6 to flow into the airbag 7 and inflate the airbag 7. This allows for simultaneous massage of the user's back and arms.

[0040] For ease of explanation, the protrusions 593 on both sides of the turntable 59 are defined as the first protrusion and the second protrusion, respectively. The teeth of the second meshing teeth on the first protrusion and the second protrusion are opposite in direction. In the initial state, the first protrusion meshes with the first rotating gear 65, and the second protrusion meshes with the second rotating gear 66. As the turntable 59 rotates, the first protrusion drives the first rotating gear 65 to rotate, thereby opening the first valve body 63; at the same time, the second protrusion drives the second rotating gear 66 to rotate, thereby opening the second valve body 64, and thus inflating the airbags 7 on the first inflation tube 61 and the second inflation tube 63; when the second protrusion rotates to mesh with the first rotating gear 65, at the same time, the first protrusion meshes with the second rotating gear 66. At this time, the first protrusion and the second protrusion can respectively drive the first rotating gear 65 and the second rotating gear 66 to return to their initial state, thereby closing the first valve body 63 and the second valve body 64.

[0041] Preferably, the first inflation tube 61 and the second inflation tube 62 have different diameters. By controlling the tube diameters, the inflation volume of the airbags on each tube can meet the different needs of the user. Of course, in this embodiment, the diameters of the first inflation tube 61 and the second inflation tube 62 can also be set to be the same; this is not a unique limitation.

[0042] Further, please refer to Figure 3 and Figure 6As shown, three airbags 7 are spaced apart at the other end of the first inflation tube 61, each airbag 7 being connected to the first inflation tube 61. By providing three airbags 7, when inflated, they form three raised points, providing a pressure massage to the patient's arm. Of course, in this embodiment, depending on the actual situation and specific needs, the number of airbags 7 can also be four, five, or other multiple numbers; this is not a specific limitation.

[0043] Further, please refer to Figure 3 and Figure 6 As shown, the first housing 1 is also equipped with vent pipes 13, which are connected to each airbag 7. Furthermore, the first housing 1 has a first through hole corresponding to each vent pipe 13, and a first sealing plug is installed in each first through hole to seal the vent pipe 13. Thus, the user can easily and conveniently deflate the airbag 7 by opening the first sealing plug according to their needs.

[0044] In this application, the airbag 7 on the first inflation tube 61 can be continuously inflated by the micro air pump 6. When the inflation amount of the airbag 7 reaches a certain amount, the first sealing plug can be opened according to the actual situation to realize the deflation of the airbag 7, thereby realizing the adjustment of the inflation amount of the airbag 7, which is efficient and convenient.

[0045] Further, please refer to Figure 3 As shown, the first housing 1 is also provided with multiple pairs of limiting plates 14, the number of which is the same as the number of vent pipes 13. In this way, by setting the limiting plates 14, the direction of the vent pipes 13 can be restricted, thereby controlling the direction of the limiting plates 14.

[0046] Further, please refer to Figure 3 As shown, the other end of the second inflation tube 62 is provided with three airbags 7 spaced apart along its extension direction, each airbag 7 being connected to the second inflation tube 62. By providing three airbags 7, when the three airbags 7 are inflated, three protruding points can be formed to achieve a pressing massage on the patient's arm. Of course, in this embodiment, depending on the actual situation and specific needs, the number of airbags 7 can also be set to four, five, or other multiples, and is not limited here.

[0047] Further, please refer to Figure 3 As shown, the second housing 2 is also equipped with vent pipes 13, which are connected to each airbag 7. Furthermore, the second housing 2 has a second through hole corresponding to each vent pipe 13, and a second sealing plug is installed in each second through hole to seal the vent pipe 13. Thus, the user can easily and conveniently deflate the airbag 7 by opening the second sealing plug according to their needs.

[0048] In this application, the airbag in the second inflation tube 62 can be continuously inflated by the micro air pump 6. When the inflation volume of the airbag 7 reaches a certain amount, the second sealing plug can be opened according to the actual situation to realize the deflation of the airbag and adjust the inflation volume of the airbag, which is efficient and convenient.

[0049] Further, please refer to Figure 3 As shown, the second housing 2 is also provided with multiple pairs of limiting plates 14, the number of which is the same as the number of vent pipes 13. In this way, by setting the limiting plates 14, the direction of the vent pipes 13 can be restricted, thereby controlling the direction of the limiting plates 14.

[0050] Further, please refer to Figure 5 As shown, the massage assembly 5 also includes a spring 551, which is sleeved on the connecting rod 55 and elastically abuts against the turntable 59. A baffle 552 is fixedly mounted on the connecting rod 55, and the baffle 552 can abut against one end of the spring 551. Thus, by setting the spring 551, one end of the spring 551 abuts against the baffle 552, and the other end of the spring 551 abuts against the turntable 59. In this way, the elastic abutment of the spring 551 against the turntable 59 ensures continuous contact between the turntable 59 and the lifting wheel assembly 58, guaranteeing subsequent massage hammering.

[0051] Further, please refer to Figure 5 As shown, one end of the connector 54 has a slot, and the connecting rod 55 has a retaining ball that can be inserted into the slot. In this way, one end of the connector 54 is connected to the connecting rod 55 through the slot and the retaining ball, thus connecting the connector 54 and the connecting rod 55; the other end of the connector 54 is hinged to the mounting base 52 through the rotating wheel 53, thereby forming a seesaw-like structure, so that the connector 54 can move synchronously with the connecting rod 55.

[0052] In this application, when the lifting rod assembly 58 drives the connecting rod 55 to rise and fall, the connecting rod 55 in turn drives one end of the connecting piece 54 to rise and fall synchronously, and the other end of the connecting piece 54 rotates around the mounting base 52 through the rotating wheel 53, so as to realize the transmission connection between the connecting rod 55 and the connecting piece 54.

[0053] In this application, the connector 54 has a spoon-shaped structure. By setting it to a spoon shape, the structure becomes more compact, and the travel of the connecting rod 55 is increased. Of course, in this embodiment, the connector 54 can also be configured with other structures according to actual conditions and specific needs, and is not limited here.

[0054] Further, please refer to Figure 5As shown, the lifting wheel assembly 58 includes a lifting rod 581, a horizontal rod 582, and an abutting wheel 583. The lifting rod 581 and the connecting rod 55 are arranged parallel to each other at intervals. The horizontal rod 582 can be used to connect the lifting rod 581 and the connecting rod 55. The abutting wheel 583 is disposed on the lifting rod 581 and abuts against the turntable 59.

[0055] In this application, when the gear assembly 8 meshes with the first tooth of the turntable 59, the turntable 59 can be driven to rotate. The turntable 59 then synchronously drives the protrusion 591 to rotate. The protrusion 591 then abuts against the abutting wheel 583 at different positions. The abutting wheel 583 then drives the lifting rod 581 to rise and fall. Under the action of the horizontal rod 582, the lifting rod 581 drives the connecting rod 55 to rise and fall. The connecting rod 55 then drives the massage head 56 to hammer the patient's arm, thereby achieving massage of the patient's arm.

[0056] In this application, there are four massage heads 56, and correspondingly, there are also four connecting rods 55. Thus, when the protrusion 591 sequentially abuts against the abutment wheels 583 at different positions, the abutment wheels 583 at different positions and the lifting rod 581 move up and down synchronously in sequence. Of course, in this application, depending on the actual situation and specific needs, the number of massage heads 56 and connecting rods 55 can also be set to five, six, seven, eight, etc., and is not limited here.

[0057] Preferably, in this application, the protrusion 591 can abut against a single abutment wheel 583. Of course, in this application, the protrusion 591 can also abut against two abutment wheels 583 simultaneously to achieve synchronous lifting and lowering of the two abutment wheels 583; of course, it can also abut against three abutment wheels 583 simultaneously, and this is not the only limitation.

[0058] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
