Description

Technical Field

[0001] This utility model relates to the technical field of massagers, and in particular to a massage interval adjustment structure and a shoulder and neck massage mechanism. Background Technology

[0002] With social progress and rapid technological development, people's work and life pace is constantly accelerating. All levels of society are busy striving for a better life, leaving little time for physical exercise. As a result, people's physical health index is declining. This situation is particularly serious among office workers who sit in front of computers and drivers who sit in the driver's seat for long periods of time. Due to the need to work at a desk or stare at a computer for long periods of time, they suffer from severe muscle strain in their neck and shoulders, poor blood circulation, and are prone to diseases such as frozen shoulder and cervical spondylosis.

[0003] Currently, many auxiliary therapeutic devices for the aforementioned health problems—neck and shoulder massagers—have appeared on the market. These devices can massage and relax the muscles in the neck and shoulder area in a short time, and consistent use can effectively relieve pain symptoms. However, the size of the neck and shoulders varies among different people. Some people have relatively thick necks and shoulders, while others have relatively thin necks or shoulders. Most existing neck and shoulder massagers use a fixed massage method, meaning the distance between the massage heads on the left and right sides of the massager is fixed and cannot be adjusted according to the user's actual needs, thus limiting the suitable user group.

[0004] In view of this, this utility model is developed by deeply conceiving and actively researching and improving the design of existing shoulder and neck massagers to address the many shortcomings and inconveniences caused by the imperfect structural design. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology in that the massage spacing cannot be adjusted, and to provide a massage spacing adjustment structure that can adjust the spacing between two sets of massage components.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A massage spacing adjustment structure includes an adjustment motor, an adjustment transmission assembly, two adjustment screws, two adjustment seats, two connecting seats, and a limiting mechanism. The adjustment transmission assembly connects the adjustment motor and the two adjustment seats. The two adjustment screws, two adjustment seats, and two connecting seats are symmetrically arranged on the long rotating shaft of the massage mechanism. The adjustment seats are connected to the adjustment transmission assembly and have an internal thread at their center. The adjustment screws have external threads that engage with the internal threads of the adjustment seats. One end of the adjustment screw is connected to the adjustment seat, and the other end is fixed to the massage assembly via the connecting seats. The limiting mechanism includes conductive probes and conductive electrode plates. The conductive probes are connected to a circuit board, and the conductive electrode plates move synchronously with the adjustment screws. The distance between the two conductive probes is less than or equal to the length of the external thread of the adjustment screws, and the conductive electrode plates are located between the two conductive probes.

[0008] Furthermore, the adjustment transmission assembly adopts gear transmission, including an adjustment drive gear, an adjustment transmission shaft, and an adjustment transmission gear. The adjustment drive gear meshes with the output shaft of the adjustment motor. The adjustment drive gear is fixedly located in the middle of the adjustment transmission shaft. An adjustment transmission gear is connected to each end of the adjustment transmission shaft. The outer periphery of the adjustment seat has an adjustment gear that meshes with the adjustment transmission gear.

[0009] Furthermore, the adjusting drive shaft is provided with a bearing between the adjusting drive gear and the two adjusting drive gears, the bearings are mounted on bearing seats, and the bearing seats are fixed to the housing.

[0010] Furthermore, the connecting seat includes a first retaining ring, a second retaining ring, and a connecting member. One end of the connecting member is locked together with the massage component, and the other end of the connecting member is provided with a first mounting ring. The end of the adjusting screw connected to the connecting seat has a second mounting ring. The first retaining ring and the second retaining ring form corresponding grooves for the first mounting ring and the second mounting ring. When the first retaining ring and the second retaining ring are engaged, the first mounting ring and the second mounting ring are limited in the grooves, thereby fixing the massage component and the adjusting screw together.

[0011] Furthermore, the conductive electrode is mounted on the second retaining ring of the connecting seat. The second retaining ring extends a guide rail to one end of the adjusting screw. The guide rail is provided with an electrode socket extending to one end of the conductive probe, and the conductive electrode is mounted on the electrode socket.

[0012] Another objective of this invention is to overcome the shortcomings of existing technologies where the massage interval cannot be adjusted, and to provide a shoulder and neck massage mechanism with an adjustable massage interval.

[0013] To achieve the above objectives, the solution of this utility model is:

[0014] A shoulder and neck massage mechanism includes a housing, a battery, a massage motor, a circuit board, a massage transmission assembly, a long rotating shaft, massage components, and a massage interval adjustment structure. The battery and the massage motor are respectively connected to the circuit board. The massage transmission assembly is connected to the massage motor and the long rotating shaft and drives the long rotating shaft to rotate through a gear transmission group. Two massage components are symmetrically arranged on the long rotating shaft. The adjustment motor is installed on the housing on one side of the long rotating shaft, and the conductive probe is installed on the housing.

[0015] Furthermore, the massage assembly includes a push rod, an eccentric wheel, a swing wheel, and a swing arm. The bottom end of the push rod is provided with a first limiting post, and the bottom end of the swing arm is provided with a second limiting post. The housing is provided with a movable groove for the first and second limiting posts to move. The eccentric wheel has an eccentric hole and a limiting groove connecting to the eccentric hole. The long rotating shaft has two pin holes at positions corresponding to the two ends of the limiting groove. The eccentric wheel and the long rotating shaft are fixed together by inserting limiting pins into the two pin holes and the limiting groove. The push rod is sleeved on the eccentric wheel, with one end of the push rod connected to the eccentric wheel. The two ends are pressed together, and the other end is locked together with the connector of the connecting seat. The top rod is positioned on the eccentric wheel through the connector. One end of the eccentric wheel is connected to the top rod, and the other end is connected to the eccentric wheel connecting piece. The eccentric wheel and the swing wheel are fixedly connected together through the eccentric wheel connecting piece. One end of the swing wheel is fixed together with the eccentric wheel connecting piece, and the other end is provided with a swing shaft. One end of the swing arm is provided with a swing hole corresponding to the swing shaft. The swing hole is sleeved on the swing shaft. The end of the swing wheel away from the swing shaft forms a swing slope. The top of the swing arm is equipped with a swing massage head.

[0016] Furthermore, the massage transmission assembly includes a drive gear and a transmission gear. The drive gear is a double gear consisting of a helical gear and a spur gear. The helical gear meshes with the output shaft of the massage motor, and the spur gear meshes with the transmission gear. The transmission gear is fixed together with the long rotating shaft.

[0017] Furthermore, the minimum distance between the two oscillating massage heads of the two sets of massage components is D1≥56mm; the minimum distance between the two top rods is D2≥57mm; the maximum distance between the two oscillating massage heads is D3≤133mm; and the maximum distance between the two top rods is D4≤75mm.

[0018] With the above structure, the shoulder and neck massage mechanism of this utility model drives the adjustment transmission component and adjustment seat to rotate by adjusting the forward or reverse rotation of the motor. When the two adjustment seats rotate, the two adjustment screws that are threaded with them will move outward or inward. When the adjustment screws move, they drive the conductive electrode plates to move. When the conductive electrode plates contact the conductive probes, the conductive probes are energized. The circuit board senses the energizing signal and causes the adjustment motor to reverse, thereby realizing that the massage components move left and right within the stroke range of the two conductive probes. This, in turn, drives the two sets of massage components connected to the two adjustment screws to expand outward or contract inward, thereby adjusting the width between the two sets of massage components. When the two sets of massage components are adjusted to the required width, the operation of the adjustment motor is stopped. This allows for arbitrary adjustment of the width within the length range between the two conductive springs, making this utility model applicable to consumers of different body types, improving the scope of application of this utility model, and enhancing its market competitiveness.

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not 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 utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] like Figures 1 to 5As shown, this utility model discloses a shoulder and neck massage mechanism, which includes a housing 1, a battery 2, a massage motor 3, a circuit board 4, a massage transmission component 5, a long rotating shaft 6, a massage component 7, and a massage interval adjustment structure 8. The battery 2 and the massage motor 3 are respectively connected to the circuit board 4. The massage transmission component 5 is connected to the massage motor 3 and the long rotating shaft 6. The massage transmission component 5 drives the long rotating shaft 6 to rotate. The two massage components 7 are symmetrically arranged on the long rotating shaft 6. The massage interval adjustment structure 8 includes an adjustment motor 81, an adjustment transmission component 82, two adjustment screws 83, two adjustment seats 84 and two connecting seats 85. The adjustment motor 81 is installed on the housing 1 on one side of the long rotating shaft 6. The adjustment transmission component 82 is connected to the adjustment motor 81 and the two adjustment seats 84. The two adjustment screws 83, the two adjustment seats 84 and the two connecting seats 85 are symmetrically arranged on the long rotating shaft 6. The adjustment seat 84 is connected to the adjustment transmission component 82. The center of the adjustment seat 84 has an internal thread 841. The adjustment screw 83 has an external thread 831 that is threaded with the internal thread 841 of the adjustment seat 84. One end of the adjustment screw 83 is connected to the adjustment seat 84, and the other end is fixed to the massage component 7 through the connecting seat 85. The forward or reverse rotation of the adjusting motor 81 drives the adjusting transmission component 82 to move. The adjusting transmission component 82 drives the two adjusting seats 84 to rotate forward or reverse. When the adjusting seats 84 rotate, they will drive the adjusting screws 83 to move closer to or further away from the adjusting seats 84, thereby driving the two sets of massage components 7 connected to the two adjusting screws 83 to move closer to or further away from each other, so that the distance between the two sets of massage components 7 increases or decreases, thereby realizing the adjustment of the massage distance.

[0031] This invention adjusts the width of the massage components 7 by setting a threaded adjusting screw 83 and an adjusting seat 84 on a long rotating shaft 6. The adjusting screw 83 is connected to the massage components 7, and the adjusting seat 84 is driven to rotate by an adjusting transmission component 82. This rotation drives the adjusting screw 83, which is threadedly connected to the adjusting seat 84, to rotate. When the adjusting screw 83 moves outward to the outer end of the long rotating shaft 6, the distance between the two massage components 7 gradually increases. When the adjusting screw 83 moves towards the center of the long rotating shaft 6, the distance between the two massage components 7 gradually decreases. Users can adjust the distance between the two massage components 7 according to their needs, thereby improving the applicability of this invention and enhancing its market competitiveness.

[0032] The massage spacing adjustment structure 8 is also provided with a limiting mechanism 86 to limit the adjustment range of the adjusting screw 83. In this embodiment, the limiting mechanism 86 includes a conductive probe 861 and a conductive electrode plate 862. The conductive probe 861 is connected to the circuit board 4. The conductive electrode plate 862 moves synchronously with the adjusting screw 83 and can be installed on the adjusting screw 83, or on the connecting seat 85 or the massage assembly 7. It can reciprocate with the adjusting screw 83. The two conductive probes 861 are set on the housing 1, and the conductive electrode plate 862 is located between the two conductive probes 861. When the adjusting screw 83 moves, it drives the conductive electrode plate 862 to move. When the conductive electrode plate 862 contacts the conductive probe 861, the conductive probe 861 is energized. The circuit board 4 senses the energizing signal and causes the adjusting motor 81 to reverse, thereby realizing the massage assembly 7 moving left and right within the stroke range of the two conductive probes 861, adjusting the distance between the two massage assemblies 7.

[0033] The adjusting transmission component 82 can be driven by a gear set or by a belt pulley, such as... Figure 1 and Figure 2 As shown, in this embodiment, the adjustment transmission assembly 82 adopts gear transmission, which includes an adjustment drive gear 821, an adjustment transmission shaft 822, and an adjustment transmission gear 823. The adjustment drive gear 821 meshes with the output shaft of the adjustment motor 81. The adjustment drive gear 821 is fixedly installed at the middle position of the adjustment transmission shaft 822. An adjustment transmission gear 823 is connected to each end of the adjustment transmission shaft 822. The outer periphery of the adjustment seat 84 has an adjustment gear 842 that meshes with the adjustment transmission gear 823. After the adjustment motor 81 is driven, its output shaft drives the adjustment drive gear 821 that meshes with it to rotate. The adjustment drive gear 821 drives the adjustment transmission shaft 822 and the adjustment transmission gear 823 to rotate synchronously. The adjustment transmission gear 823 then drives the adjustment gear 842 that meshes with it to rotate, thereby realizing the relative movement between the adjustment screw 83 and the adjustment seat 84.

[0034] Preferably, the adjusting drive shaft 822 is provided with a bearing 824 between the adjusting drive gear 821 and the two adjusting drive gears 823. The bearing 824 is mounted on a bearing seat 825, which is fixed to the housing 1. The bearing can reduce the frictional resistance of the adjusting drive shaft 822 and reduce energy loss. In addition, the bearing 824 can provide precise radial and axial positioning for the adjusting drive shaft 822, limit the radial and axial displacement of the adjusting drive shaft 822, and ensure that the adjusting drive shaft 822 rotates stably on the preset trajectory.

[0035] In this embodiment, the connecting seat 85 includes a first retaining ring 851, a second retaining ring 852, and a connecting member 853. One end of the connecting member 853 is locked together with the massage component 7, and the other end of the connecting member 853 is provided with a first mounting ring 854. The end of the adjusting screw 83 connected to the connecting seat 85 has a second mounting ring 832. The first retaining ring 851 and the second retaining ring 852 form corresponding grooves 855 for the first mounting ring 854 and the second mounting ring 832. When the first retaining ring 851 and the second retaining ring 852 are engaged, the first mounting ring 854 and the second mounting ring 832 are limited in the grooves 855, thereby fixing the massage component 7 and the adjusting screw 83 together.

[0036] Cooperate Figure 4 As shown, there are multiple ways to install the conductive electrode plate 862. In this embodiment, the conductive electrode plate 862 is installed on the second retaining ring 852 of the connecting seat 85. A guide rail 856 extends from the second retaining ring 852 to one end of the adjusting screw 83. An electrode socket 857 extending from the guide rail 856 to one end of the conductive probe 861 is provided. The conductive electrode plate 862 is installed on the electrode socket 857.

[0037] like Figure 5 As shown, in this embodiment, the massage component 7 includes a top rod 71, an eccentric wheel 72, an eccentric wheel 73, and a swing arm 74. The bottom end of the top rod 71 is provided with a first limiting post 711, and the bottom end of the swing arm 74 is provided with a second limiting post 741. The housing 1 is provided with a movable groove 11 for the first limiting post 711 and the second limiting post 741 to move. The eccentric wheel 72 is provided with an eccentric hole 721 and a limiting groove 722 that connects to the eccentric hole 721. The long rotating shaft is provided with two pin holes at the positions corresponding to the two ends of the limiting groove 722. The eccentric wheel 72 and the long rotating shaft 6 are fixed together by inserting the limiting pins into the two pin holes and the limiting groove 722. The push rod 71 is sleeved on the eccentric wheel 72. One end of the push rod 71 abuts against the eccentric wheel 72, and the other end is locked together with the connecting piece 853 of the connecting seat 85. The push rod 71 is positioned on the eccentric wheel 72 by the connecting piece 853. One end of the eccentric wheel 72 is connected to the top rod 71, and the other end is connected to the eccentric wheel connecting piece 75. The eccentric wheel 72 and the swing wheel 73 are fixedly connected together by the eccentric wheel connecting piece 75. One end of the swing wheel 73 is fixed to the eccentric wheel connecting piece 75, and the other end is provided with a swing shaft 731. One end of the swing arm 74 is provided with a swing hole 742 corresponding to the swing shaft 731. The swing hole 742 is sleeved on the swing shaft 731. The end of the swing wheel 73 facing away from the swing shaft 731 forms a swing inclined surface 732. The top end of the swing arm 74 is equipped with a swing massage head 75. In this embodiment, the massage transmission assembly 5 includes a drive gear and a transmission gear ( Figure 1(The motor cover blocks the drive gear, which is a double gear with helical and spur gears. The helical gear meshes with the output shaft of the massage motor 3, and the spur gear meshes with the transmission gear. The transmission gear is fixed together with the long rotating shaft 6.)

[0038] When the adjustable massage mechanism of this invention is in operation, the battery powers the circuit board, which controls the massage motor 3 to operate. The massage motor 3 drives the drive gear, which in turn drives the transmission gear and the long rotating shaft 6. The long rotating shaft 6 drives the eccentric wheel 72 and the swing wheel 73 to rotate, which in turn drives the top rod 71 to rotate. The top rod 71 is limited by the second limiting post 741, allowing its free end to move up and down within a certain range. Because the swing wheel 73 has a swinging inclined surface 732, under the action of the first limiting post 711, the swing arm 74 sleeved on the swing shaft 731 can swing left and right when the long rotating shaft 6 rotates, effectively clamping the neck. Combined with the top rod 71, this achieves a kneading and pinching massage effect. The distance between the two sets of massage components 7 can be adjusted by changing the forward or reverse rotation of the motor 81.

[0039] like Figure 6 As shown, when the massage component 7 of this utility model moves to the conductive probe 861 near the center of the long rotating shaft 6 under the drive of the adjusting screw 83, the distance between the two oscillating massage heads 75 and the two top rods 71 ​​between the two sets of massage components 7 is the smallest. The minimum distance D1 between the two oscillating massage heads 75 is ≥56; the minimum distance D2 between the two top rods 71 ​​is ≥57.

[0040] like Figure 7 As shown, when the massage component 7 of this utility model moves outward to the conductive probe 861 located on the outer side driven by the adjusting screw 83, the distance between the two oscillating massage heads 75 and the two top rods 71 ​​between the two sets of massage components 7 is at its maximum. The maximum distance D3 between the two oscillating massage heads 75 is ≤133mm; the maximum distance D4 between the two top rods 71 ​​is ≤75mm. The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
