Description

Technical Field

[0001] This utility model relates to the field of massager technology, and more specifically, to a thin back massager that can move up and down for use in wheelchairs. Background Technology

[0002] For people with mobility impairments, wheelchairs can cause back and waist fatigue from prolonged sitting, which urgently needs relief. Because the size of a wheelchair limits the size of the backrest, a thin and lightweight massage mechanism is required. A mechanism that is too large or too thick is unsuitable, and one that is too heavy will affect mobility. Therefore, there is a market demand for thin massagers suitable for wheelchairs. Utility Model Content

[0003] This invention overcomes the shortcomings of the prior art. Its structure is reasonably designed and can realize back massage for people with limited mobility. It also features a compact structure, lightweight body and up-and-down moving massage function.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A thin, vertically movable back massager for wheelchairs includes a frame and a core module vertically movable within the frame. The core module includes a housing, a kneading assembly, and a walking assembly. The kneading assembly includes a kneading motor, a kneading arm with a massage head, and a gear set connecting the kneading motor and the kneading arm. The kneading arm is located on the outside of the housing. The walking assembly includes a walking motor, a walking gear connected to the walking motor, and a connecting rod connecting the walking gear and the frame. One end of the connecting rod is eccentrically connected to the walking gear, and the other end of the connecting rod is connected to the upper or lower end of the frame.

[0005] By adopting the above technical solution, the massager of this product is specifically installed on the backrest of a wheelchair, providing a lumbar and back massage for people with limited mobility. Specifically, the kneading motor in the kneading assembly drives a gear set, which in turn drives the kneading arms to move, thus achieving the massage effect. Meanwhile, the walking motor in the walking assembly drives the walking gear to rotate. Since one end of the connecting rod is eccentrically connected to the walking gear, and the other end is connected to the frame, when the walking gear rotates, the connection point between the connecting rod and the walking gear moves between the nearest and farthest ends relative to the frame, thereby achieving the reciprocating up-and-down movement of the housing relative to the frame. Furthermore, because the kneading arms are located on the outer side of the housing, the overall thickness of the housing can be effectively reduced, thus reducing the overall weight of the massager.

[0006] Preferably, the gear set includes a transmission gear, the kneading arm is eccentrically connected to the transmission gear, the kneading arm is provided with a strip groove, and the machine housing is provided with a column located in the strip groove.

[0007] By adopting the above technical solution, the column is located in the strip groove. When the transmission gear rotates, the eccentric connection between the kneading arm and the transmission gear will change position along the circumference of the transmission gear. Furthermore, the kneading arm will move along the trajectory of the strip groove, thereby realizing the reciprocating swing of the kneading arm and increasing massage comfort.

[0008] Preferably, a stabilizing plate is connected to the column above the strip groove, and an installation groove is provided on the kneading arm. The strip groove is located in the installation groove, and the stabilizing plate abuts against the bottom surface of the installation groove or has a gap between it and the bottom surface of the installation groove.

[0009] By adopting the above technical solution, the stabilizing plate ensures smoother movement of the strip groove relative to the column, preventing the strip from detaching from the column. The stabilizing plate can either abut against the bottom surface of the mounting groove or have a gap between it and the bottom surface of the mounting groove; both solutions effectively prevent the strip from detaching from the column, ensuring smooth operation of the kneading arm.

[0010] Preferably, two kneading arms are symmetrically arranged, and each kneading arm is provided with two massage heads, with the strip groove located between the two massage heads.

[0011] By adopting the above technical solution, the two massage heads are located at both ends of the kneading arm, while the strip groove is located between the two massage heads. In this way, as the kneading arm swings, the two massage heads can change their positions, thereby further improving the massage comfort.

[0012] Preferably, the kneading motor is configured as a dual-head motor, and the gear set is provided in two sets. Each gear set includes a transmission gear and an intermediate gear that is connected between the dual-head motor and the transmission gear. The dual-head motor, the intermediate gear and the transmission gear are all installed in the machine housing.

[0013] By adopting the above technical solution, and by setting up a dual-head motor to drive the two gear sets and the kneading arm, the overall size and weight of the machine casing are further reduced.

[0014] Preferably, there are two traveling gears and two connecting rods. The two connecting rods are respectively connected to the two traveling gears. The traveling motor is located between the two traveling gears and drives the two traveling gears simultaneously. The connecting rods are located inside the housing.

[0015] By adopting the above technical solution, one walking motor can drive two walking gears to rotate, which can reduce the overall size of the housing. Furthermore, the connecting rod is placed in the housing, which can provide better protection for the connecting rod. In addition, the connecting rod is a flat rod-shaped component, which does not occupy too much internal space of the housing.

[0016] Preferably, the frame includes a vertically arranged guide rail, the housing is positioned on the guide rail, and the housing is provided with locking blocks located on both sides of the guide rail.

[0017] By adopting the above technical solution, the housing is specifically set to move up and down along the guide rail. By setting two locking blocks on the housing, the guide rail is located between the two locking blocks, thus achieving good positioning of the housing. Specifically, the housing includes two detachable upper and lower parts, with the two locking blocks located in the two parts respectively, thus making it easy to install the housing on the guide rail.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-6As shown, a thin back massager for wheelchairs that can move up and down includes a frame 1 and a core module 2 that can move up and down in the frame 1. The core module 2 includes a housing 3, a kneading component 4, and a walking component 5. The kneading component 4 includes a kneading motor 41, a kneading arm 42 with a massage head 421, and a gear set 43 that is driven between the kneading motor 41 and the kneading arm 42. The kneading arm 42 is located on the outside of the housing 3. The walking component 5 includes a walking motor 51, a walking gear 52 that is driven between the walking motor 51, and a connecting rod 53 that connects the walking gear 52 and the frame 1. One end of the connecting rod 53 is eccentrically connected to the walking gear 52, and the other end of the connecting rod 53 is connected to the upper or lower end of the frame 1.

[0022] By adopting the above technical solution, the massager of this product is specifically installed on the backrest of a wheelchair 100, providing a back massage for people with limited mobility. Specifically, the kneading motor 41 in the kneading assembly 4 drives the gear set 43, which in turn drives the kneading arm 42 to move, thus achieving the massage effect. Meanwhile, the walking motor 51 in the walking assembly 5 drives the walking gear 52 to rotate. Since one end of the connecting rod 53 is eccentrically connected to the walking gear 52, and the other end of the connecting rod 53 is connected to the frame 1, when the walking gear 52 rotates, the connection point between the connecting rod 53 and the walking gear 52 moves between the nearest and farthest ends relative to the frame 1, thereby realizing the up-and-down reciprocating movement of the housing 3 relative to the frame 1. Furthermore, since the kneading arm 42 is located on the outside of the housing 3, the overall thickness of the housing 3 can be effectively reduced, thus reducing the overall weight of the massager.

[0023] The gear set 43 includes a transmission gear 431, and a kneading arm 42 is eccentrically connected to the transmission gear 431. The kneading arm 42 has a strip groove 422, and the housing 3 has a column 31 located within the strip groove 422. When the transmission gear 431 rotates, the eccentric connection between the kneading arm 42 and the transmission gear 431 changes position circumferentially along the transmission gear 431, and the kneading arm 42 moves along the trajectory of the strip groove 422, thereby achieving the reciprocating oscillation of the kneading arm 42 and increasing massage comfort.

[0024] A stabilizing plate 32 is connected to the column 31 above the strip groove 422. The kneading arm 42 has a mounting groove 423, in which the strip groove 422 is located. The stabilizing plate 32 abuts against the bottom surface of the mounting groove 423 or has a gap between it and the bottom surface of the mounting groove 423. The stabilizing plate 32 ensures smoother movement of the strip groove 422 relative to the column 31, preventing it from detaching from the column 31. The stabilizing plate 32 can abut against the bottom surface of the mounting groove 423 or have a gap between it and the bottom surface of the mounting groove 423; both methods effectively prevent the strip groove from detaching from the column 31, ensuring smooth operation of the kneading arm 42.

[0025] Furthermore, two kneading arms 42 are symmetrically arranged, and each kneading arm 42 is equipped with two massage heads 421. A strip groove 422 is located between the two massage heads 421. The two massage heads 421 are located at opposite ends of the kneading arm 42, while the strip groove 422 is located between the two massage heads 421. In this way, as the kneading arm 42 swings, the two massage heads 421 can change their positions, thereby further improving the massage comfort.

[0026] The kneading motor 41 is configured as a dual-head motor, and the gear set 43 is provided in two sets. Each gear set 43 includes a transmission gear 431 and an intermediate gear 432 that is connected between the dual-head motor and the transmission gear 431. The dual-head motor, the intermediate gear 432 and the transmission gear 431 are all installed in the machine housing 3. By setting the dual-head motor, the transmission of the two gear sets 43 and the kneading arm 42 is realized, further reducing the overall size and weight of the machine housing 3.

[0027] In addition, there are two traveling gears 52 and two connecting rods 53. The two connecting rods 53 are respectively connected to the two traveling gears 52. The traveling motor 51 is located between the two traveling gears 52 and drives both traveling gears 52 simultaneously. The connecting rods 53 are located inside the housing 3. The two traveling gears 52 can be driven to rotate by one traveling motor 51, which can reduce the overall size of the housing 3. Furthermore, placing the connecting rods 53 in the housing 3 can provide better protection for the connecting rods 53. Moreover, the connecting rods 53 are flat rod-shaped components, which do not occupy excessive internal space of the housing 3.

[0028] Furthermore, the frame 1 includes a vertically arranged guide rail 11, and the housing 3 is positioned on the guide rail 11. The housing 3 is provided with locking blocks 33 located on both sides of the guide rail 11. Specifically, the housing 3 is moved up and down along the guide rail 11. By providing two locking blocks 33 on the housing 3, the guide rail 11 is positioned between the two locking blocks 33, thus achieving good positioning of the housing 3. Specifically, the housing 3 includes two detachable upper and lower parts, with the two locking blocks 33 located in the two parts respectively, thus facilitating the installation of the housing 3 on the guide rail 11.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
