[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0022] Please combine Figure 1-4 The utility model discloses a massage device 10 with a suspension lubrication structure that can reduce friction, reduce component wear, and extend service life. The massage device at least includes a massage component 100 and a power mechanism 200 that drives the massage component 100 to move. In this embodiment, the power mechanism 200 is a rotary motor. In other embodiments, according to the needs of the user, the power mechanism 200 can also be a manual drive mechanism. For example, the power mechanism 200 can include a rotating handle, a gear set connected to the rotating handle, and an output shaft connected to the output end of the gear set. Of course, the power mechanism 200 can also be other transmission mechanisms that can be manually operated to drive the output shaft to rotate, thereby driving the massage component 100 to move. The massage device also includes a bottom shell for mounting the power mechanism 200 and the massage component 100. The massage component 100 at least includes a first pinching bracket 110 and an eccentric wheel 120. That is, the massage device of this embodiment can at least massage one part of the user's body. One end of the first pinching bracket 110 is provided with a first through hole 111 that runs through two opposite sides thereof, and the other end of the first pinching bracket 110 is provided with a first massage head 112. In this embodiment, the first massage head 112 is fixedly disposed at the end of the first pinch bracket 110, so as to press the user's shoulder under the drive of the first pinch bracket 110 and slide along the user's shoulder to achieve the purpose of massaging the shoulder. Further, in this embodiment, a connecting arm adapted to the user's shoulder curve is formed between the first through hole 111 and the first massage head 112 on the first pinch bracket 110 to prevent the first pinch bracket 110 from scratching the user's shoulder when in use.
[0023] The eccentric wheel 120 is used to convert the rotation of the power mechanism 200 into the swing of the first pinching bracket 110. Specifically, the eccentric wheel 120 is embedded in the first through hole 111, and a rotating shaft 121 extending out of the first through hole 111 is eccentrically arranged on one side of the eccentric wheel 120. The power mechanism 200 is located on the other side of the eccentric wheel 120 and is coaxially arranged with the rotating shaft 121 to drive the eccentric wheel 120 to rotate. When the output shaft of the power mechanism 200 drives the eccentric wheel 120 to rotate, since the rotation center of the eccentric wheel 120 is located at the non-geometric center of the eccentric wheel 120, the eccentric wheel 120 will periodically push the first pinching bracket 110 to make the first pinching bracket 110 swing to massage the user's shoulders. Further, a first gap is formed between the annular side surface of the eccentric wheel 120 and the inner side surface of the first through hole 111, and a plurality of first grooves 122 are provided at intervals on the annular side surface of the eccentric wheel 120 or the inner side surface of the first through hole 111, and a first grease layer 123 is provided in the first gap and the first groove 122, and the first grease layer 123 is in liquid or paste form. In this embodiment, a plurality of first grooves 122 are provided at intervals on the annular side surface of the eccentric wheel 120. Further preferably, the first groove 122 extends along the axial direction of the eccentric wheel 120. It can be understood that the first gap and the first groove 122 are respectively filled with grease, so that the first holding bracket 110 and the eccentric wheel 120 cooperate in a "quasi-suspension" manner, avoiding wear caused by hard contact between the first holding bracket 110 and the eccentric wheel 120, and reducing wear and friction. In addition, when the first grease layer 123 is provided in the first gap and the first groove 122, the noise generated by friction during hard contact can be improved, and the transmission efficiency between the eccentric wheel 120 and the first clamping bracket 110 can be improved. At the same time, the problem of excessive temperature caused by friction in the matching part of the eccentric wheel 120 and the first clamping bracket 110 can also be improved under heavy load conditions.
[0024] In one embodiment, a plug hole 124 is eccentrically provided on a side of the eccentric wheel 120 that is away from the rotating shaft 121, and the output shaft of the power mechanism 200 is inserted into the plug hole 124 and circumferentially fixed to the eccentric wheel 120 to drive the eccentric wheel 120 to rotate. Preferably, the plug hole 124 includes a circular hole eccentrically opened on the eccentric wheel 120, and a square hole connected to the circular hole and extending to the middle of the eccentric wheel 120. The outer contour of the output shaft of the power mechanism 200 is adapted to the inner contour of the plug hole 124. In this way, the output shaft of the power mechanism 200 can be constrained by the inner wall of the square hole to avoid relative rotation between the output shaft of the power mechanism 200 and the eccentric wheel 120, thereby ensuring the reliability of power transmission between the power mechanism 200 and the eccentric wheel 120.
[0025] Furthermore, the massage component also includes an axial cam 130 and a second pinching bracket 140. In this case, the massage device can massage two parts of the user's body at the same time. Specifically, in this embodiment, the first pinching bracket 110 and the second pinching bracket 140 are used to contact the user's shoulder and neck respectively, and the eccentric wheel 120 and the axial cam 130 are used as transmission components of the power mechanism 200, which are used to transmit the rotation of the power mechanism 200 to the first pinching bracket 110 and the second pinching bracket 140, so that the first pinching bracket 110 and the second pinching bracket 140 act simultaneously. Preferably, the first pinching bracket 110 and the second pinching bracket 140 are cross-arranged and together enclose a massage area to massage the user's shoulders and neck at the same time.
[0026] The axial cam 130 is located at one side of the first pinching bracket 110 and is drivingly connected to the end of the rotating shaft 121. A cylindrical protrusion 131 is provided on the side of the axial cam 130 facing away from the first pinching bracket 110. The second pinching bracket 140 is located at one side of the axial cam 130 and adjacent to the cylindrical protrusion 131. A second through hole 141 is provided at one end of the second pinching bracket 140, which penetrates through two opposite sides thereof and is embedded with the cylindrical protrusion 131. A second gap is formed between the inner side of the second through hole 141 and the annular side of the cylindrical protrusion 131. A plurality of second grooves 132 are spaced apart on the annular side of the cylindrical protrusion 131 or the inner side of the second through hole 141. A second grease layer is provided in the second groove 132 and the second gap. At least one second massage head 142 is installed at the other end of the second pinching bracket 140. Preferably, in this embodiment, a plurality of second grooves 132 are spaced apart on the annular side of the cylindrical protrusion 131. Further preferably, the second groove 132 extends along the axial direction of the cylindrical protrusion 131. It can be understood that the second gap and the second groove 132 are respectively filled with grease, so that the second pinching bracket 140 and the cylindrical protrusion 131 are matched in a "quasi-suspension" manner, avoiding the wear caused by the hard contact between the second pinching bracket 140 and the cylindrical protrusion 131, and reducing wear and friction. In addition, when the second grease layer is provided in the second gap and the second groove 132, the noise generated by the friction during the hard contact can be improved, and the transmission efficiency between the axial cam 130 and the second pinching bracket 140 can be improved. At the same time, the problem of excessive temperature caused by friction at the matching part of the axial cam 130 and the second pinching bracket 140 can also be improved under heavy load.
[0027] Furthermore, the side of the second pinching bracket 140 facing away from the first pinching bracket 110 is limitedly matched with the bottom shell, and the side of the axial cam 130 adjacent to the first pinching bracket 110 is provided with an uneven convex portion 133 extending along the axial direction of the rotating shaft 121, and the distances from various parts of the uneven convex portion 133 to the side of the first pinching bracket 110 are different (that is, the heights of various parts of the uneven convex portion 133 are different), and the end surface of the uneven convex portion 133 is a smooth continuous arc surface. In this way, when the rotating shaft 121 drives the axial cam 130 to rotate, the axial cam 130 is relative to the first pinching bracket 110. The holding bracket 110 rotates synchronously, and the uneven protrusion 133 on the axial cam 130 rotates along the side of the first pinching bracket 110. In order to adapt to the changes in the height of each part of the uneven protrusion 133 and the constraint of the bottom shell on the second pinching bracket 140, the axial cam 130 will perform a composite motion of rotation and translation relative to the first pinching bracket 110, that is, the axial cam 130 will twist relative to the first pinching bracket 110, thereby further driving the second pinching bracket 140 to twist relative to the first pinching bracket 110, so as to massage the user's neck through the second massage head 142.
[0028] It can be understood that the massage device of this embodiment is provided with a suspension-like drag reduction structure at the matching position between the eccentric wheel 120 and the first pinching bracket 110 and the matching position between the cylindrical protrusion 131 and the second pinching bracket 140, respectively, so as to convert the hard contact of sliding friction into the matching between grease, thereby achieving the purpose of reducing friction. Preferably, the second grease layer is in liquid or paste form. In actual design, the cross-sectional shape of the first groove and the cross-sectional shape of the second groove can be set as needed. For example, the cross-sectional shapes of the two can be rectangular, semicircular, or other shapes with internal depressions.
[0029] In one embodiment, the annular side surface of the eccentric wheel 120 is provided with a plurality of first grooves 122 at intervals, the inner side surface of the first through hole 111 is provided with a plurality of first dividing grooves at intervals to divide the inner side surface of the first through hole 111 to form a plurality of first bosses 113, or the inner side surface of the first through hole 111 is provided with a plurality of first grooves at intervals, and the annular side surface of the eccentric wheel 120 is provided with a plurality of first dividing grooves at intervals to divide the annular side surface of the eccentric wheel to form a plurality of first bosses. The annular side surface of the cylindrical protrusion is provided with a plurality of second grooves 132 at intervals, the inner side surface of the second through hole 141 is provided with a plurality of second dividing grooves at intervals to divide the inner side surface of the second through hole 141 to form a plurality of second bosses, or the inner side surface of the second through hole 141 is provided with a plurality of second grooves at intervals, and the annular side surface of the cylindrical protrusion is provided with a plurality of second dividing grooves at intervals to divide the annular side surface of the cylindrical protrusion to form a plurality of second bosses.
[0030] Preferably, please combine Figure 3 and Figure 4In this embodiment, the eccentric wheel 120 has a plurality of first grooves 122 spaced apart on the side surface thereof, and the inner side surface of the first through hole 111 has a plurality of first separation grooves spaced apart on the inner side surface thereof to divide the inner side surface of the first through hole 111 to form a plurality of first bosses 113. The distance between adjacent first grooves 122 is ( Figure 4 a) is smaller than the width of a single first boss 113 ( Figure 4 c); the annular side surface of the cylindrical protrusion is provided with a plurality of second grooves 132 at intervals, and the inner side surface of the second through hole 141 is provided with a plurality of second dividing grooves at intervals to divide the inner side surface of the second through hole 141 to form a plurality of second bosses, and the distance between adjacent second grooves 132 is less than the width of a single second boss. In this embodiment, by providing the first dividing groove and the second dividing groove, the setting area of the grease is increased, and the lubrication effect between the eccentric wheel 120 and the first holding bracket 110, and between the cylindrical protrusion 131 and the second holding bracket 140 is further improved, and the friction force is reduced. By making the gap width between adjacent first grooves 122 smaller than the width of a single first boss 113 and the distance between adjacent second grooves 132 smaller than the width of a single second boss, it is beneficial to increase the area of the first groove 122 on the eccentric wheel 120 and the area of the second groove 132 on the cylindrical protrusion 131, thereby improving the supporting effect of the eccentric wheel 120 on the first pinching bracket 110 and the supporting effect of the cylindrical protrusion 131 on the second pinching bracket 140, thereby ensuring the structural strength of the massage device.
[0031] Furthermore, in one embodiment, the width of a single first boss 113 ( Figure 4 c) and the width of a single first groove 122 ( Figure 4 The ratio of b) in the figure is greater than or equal to 3; the ratio of the width of a single second boss to the width of a single second groove 132 is greater than or equal to 3, so as to ensure the firmness of the fit between the eccentric wheel 120 and the first holding bracket 110 and the firmness of the fit between the cylindrical protrusion 131 and the second holding bracket 140. In addition, a third boss is formed between adjacent first grooves 122, and the width of the third boss is smaller than the width of the first groove 122; a fourth boss is formed between adjacent second grooves 132, and the width of the fourth boss is smaller than the width of the second groove 132. In addition, in order to reduce the difficulty of the process, the width of the first boss 113 ( Figure 4 c) in the figure can be as long as possible to facilitate processing of the suspension lubrication structure. However, since the increase in the width of the first boss 113 will lead to a decrease in the suspension lubrication effect, the first boss 113 is constrained by the width of the first groove 122 and cannot be infinitely enlarged.
[0032] In this embodiment, n2=a / b (a is the distance between adjacent first grooves 122, b is the width of a single first groove 122), wherein b is smaller than a, i.e., the width of a single first groove 122 is smaller than the distance between adjacent first grooves 122. In order to ensure the support strength of the eccentric wheel 120 to the first holding bracket 110, b should be as close to a as possible, i.e., n2 should be as small as possible while ensuring the mechanical strength of the connection between the eccentric wheel 120 and the first holding bracket 110. Since the closer b is to a, the thinner the third boss becomes, and when it contacts the first holding bracket 110, the support will become unstable. Therefore, the size adjustment of a and b is based on the premise that the eccentric wheel 120 stably supports the first holding bracket 110. Similarly, the cooperation between the cylindrical protrusion 131 and the second holding bracket 140 is the same.
[0033] In one embodiment, a recessed groove 114 is formed on each end of the first through hole 111 on the first pinching bracket 110, and an edge of the eccentric wheel 120 facing away from the rotating shaft 121 is raised to form a first sealing ring 125 for embedding in the recessed groove 114 on one side of the first through hole 111. A second sealing ring 134 is provided on the side of the axial cam 130 adjacent to the first pinching bracket 110 for embedding in the recessed groove 114 on the other side of the first through hole 111 and sealing the first groove 122; a side surface of the axial cam 130 adjacent to the second pinching bracket 140 abuts against the outer edge of one end of the second through hole 141, and a sealing plate 150 is provided on the side of the second pinching bracket 140 facing away from the axial cam 130, which is axially fixed to the axial cam 130 to seal the other end of the second through hole 141. In this way, the outflow of grease between the first groove 122 and the first gap can be avoided, and the outflow of grease between the second groove 132 and the second gap can be avoided, thereby maintaining the stability of the first grease layer 123 and the second grease layer, and improving the reliability of lubrication between the eccentric wheel 120 and the first pinching bracket 110 and the reliability of lubrication between the cylindrical protrusion 131 and the second pinching bracket 140.
[0034] Furthermore, in one embodiment, two limiting shafts 143 are arranged at the end of the second pinching bracket 140 facing away from each other, and a second massage head 142 is rotatably mounted on each of the two limiting shafts 143, and the axial direction of the first massage head 112 is perpendicular to the axial direction of the second massage head 142. In this way, the massage area of the user's neck by the second pinching bracket 140 is increased. While the second pinching bracket 140 drives the two second massage heads 142 to twist to press the user's neck, it also rolls on the user's neck by rotating to improve the comfort of the massage.
[0035] In one embodiment, two massage components 100 are arranged opposite to each other on both sides of the power mechanism 200, and two output shafts are arranged on the power mechanism 200 in opposite directions, and the two output shafts are respectively connected to the eccentric wheel 120 of one massage component 100. In this embodiment, a single massage component 100 massages the shoulder and neck of the user on one side. Thus, by arranging a massage component 100 on each side of the power mechanism 200, the shoulders and neck of the user can be massaged at the same time on both sides of the shoulder, so as to simulate the situation of pressing the shoulders and neck with both hands, and at the same time increase the massage area of the user, thereby improving the massage effect.
[0036] The massage device 10 with a quasi-suspended lubrication structure of the utility model is implemented by opening a first groove 122 on the eccentric wheel 120 or the first through hole 111, setting a first gap between the eccentric wheel 120 and the first through hole 111, and setting a first grease layer 123 in the first groove 122 and the first gap. During the rotation of the first pinching bracket 110, the first pinching bracket 110 cooperates with the eccentric wheel 120 through the first grease layer 123, thereby reducing the friction and wear of the first pinching bracket 110 during the rotation process, which is beneficial to extending the service life of the friction device.
[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
