[0066] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0067] Reference below Figure 1-Figure 19 A massage movement 100 according to an embodiment of the present invention is described.

[0068] like Figure 1-Figure 3 As shown, the massage movement 100 according to the embodiment of the utility model includes a housing 11, the housing 11 includes a bottom wall 111 and a peripheral wall 112, the bottom wall 111 has a first side 101 and a second side 102 arranged opposite to each other, the first side 101 of the bottom wall 111 and the second side 102 of the bottom wall 111 are arranged opposite to each other in the thickness direction of the bottom wall 111, specifically, the first side 101 of the bottom wall 111 is Figure 1 and Figure 3 The front side shown in FIG. 1 and the second side 102 of the bottom wall 111 are as shown in FIG. Figure 1 and Figure 3 The peripheral wall 112 is disposed on the first side 101 of the bottom wall 111 , and an installation space 110 is formed between the peripheral wall 112 and the bottom wall 111 .

[0069] The massage movement 100 also includes a massage component 20 and a driving device 30 . The massage component 20 and the driving device 30 are arranged in the installation space 110 . The driving device 30 is connected to the massage component 20 , and the driving device 30 can drive the massage component 20 to move.

[0070] Furthermore, the massage movement 100 also includes a circuit board (not shown in the figure) and a battery 60 . The circuit board is electrically connected to the driving device 30 , and the battery 60 is used to supply power to the circuit board and the driving device 30 .

[0071] Among them, Figure 4 As shown, a first receiving groove 114 is further provided on a side of the bottom wall 111 of the housing 11 facing away from the installation space 110 (i.e., the side where the second side 102 of the bottom wall 111 is located), and one of the circuit board and the battery 60 is installed in the first receiving groove 114. In other words, the massage component 20 and the driving device 30 are located on the first side 101 in the thickness direction of the bottom wall 111, and the circuit board and the battery 60 are located on the second side 102 in the thickness direction of the bottom wall 111, and the massage component 20 and the driving device 30, the circuit board or the battery 60 are separated by the bottom wall 111 of the housing 11.

[0072] According to the massage movement 100 of the embodiment of the utility model, by arranging one of the circuit board and the battery 60 in the first accommodating groove 114, that is, arranging the circuit board or the battery 60 on the side of the shell 11 facing away from the massage component 20 and the drive device 30, on the one hand, the shell 11 is used to separate the circuit board or the battery 60, the massage component 20 and the drive device 30, which can avoid interference between the circuit board or the battery 60 and the massage component 20 and the drive device 30, thereby ensuring that each component can work normally, and on the other hand, it is possible to eliminate the need to arrange the installation structure of the circuit board or the battery 60 in the installation space 110 of the shell 11, simplifying the structure in the installation space 110 of the shell 11, reducing the thickness of the massage movement 100, simplifying the production process, and helping to improve production efficiency. It is also possible to make more space in the installation space 110 for placing the massage component 20 and the drive device 30.

[0073] like Figure 4 As shown, according to some embodiments of the present invention, a second receiving groove 115 is further provided on a side of the bottom wall 111 facing away from the installation space 110 , and the other of the circuit board and the battery 60 is provided in the second receiving groove 115 .

[0074] In the above technical solution, the other of the circuit board and the battery 60 is arranged in the second accommodating groove 115, that is, the massage component 20 and the driving device 30 are located on the first side 101 in the thickness direction of the bottom wall 111, and the circuit board and the battery 60 are located on the second side 102 in the thickness direction of the bottom wall 111. The massage component 20 and the driving device 30, the circuit board and the battery 60 are separated by the bottom wall 111 of the shell 11, which can avoid interference between the circuit board and the battery 60 and the driving device 30, the massage component 20, etc., and also eliminates the need to set the mounting structure of the circuit board and the battery 60 inside the shell 11. Further, it can avoid interference with the driving device 30, the massage component 20, etc., and also eliminates the need to set the mounting structure of the circuit board and the battery 60 inside the shell 11.

[0075] In some embodiments, the driving device 30 includes a driving motor 311 and a reduction mechanism 312, the driving motor 311 is connected to the reduction mechanism 312, and the output shaft 32 of the reduction mechanism 312 is connected to the massage component 20. The reduction mechanism 312 can reduce the rotation speed of the motor shaft of the driving motor 311, so that the movement speed of the massage component 20 can meet the demand.

[0076] Among them, the driving motor 311 and the circuit board are arranged opposite to each other in the thickness direction of the shell 11, and the reduction mechanism 312 and the battery 60 are arranged opposite to each other in the thickness direction of the shell 11. That is to say, it is equivalent to laying the driving motor 311, the reduction mechanism 312, the circuit board and the battery 60 flat on opposite sides of the thickness direction of the shell 11, which is beneficial to improving the space utilization rate of the shell 11 and reducing the thickness of the massage movement 100.

[0077] Furthermore, a wire hole 1142 is provided on the bottom wall of the first receiving groove 114 , and the driving motor 311 is connected to the circuit board through a wire, and the wire passes through the wire hole 1142 .

[0078] Therefore, by arranging the drive motor 311 and the circuit board relative to each other in the thickness direction of the shell 11, on the one hand, it is convenient for the wires of the drive motor 311 to be routed through the wire holes 1142 to connect with the circuit board, and on the other hand, it is beneficial to shorten the length of the wires between the drive motor 311 and the circuit board, thereby reducing costs.

[0079] like Figure 4 As shown, in some examples, the driving motor 311 and the speed reduction mechanism 312 are arranged along the width direction of the housing 11 , and the first receiving groove 114 and the second receiving groove 115 are arranged along the width direction of the housing 11 .

[0080] Such an arrangement effectively utilizes the space in the width direction of the shell 11. On the one hand, it reduces the occupied space in the thickness direction of the shell 11, so that the thickness of the massage movement 100 can be reduced thinner. On the other hand, compared with the arrangement of the drive motor 311 and the reduction mechanism 312 along the length direction of the shell 11, the space utilization is more reasonable, leaving space for the massage component 20, and the overall length of the massage movement 100 will not be too long.

[0081] like Figure 4 and Figure 5 As shown, in some examples, a portion of the bottom wall 111 is recessed toward the receiving groove where the circuit board is located to form a recess 1141, a portion of the drive motor 311 is disposed in the recess 1141, and a wire hole 1142 is disposed on the side wall of the recess 1141 close to the deceleration mechanism 312.

[0082] The shape of the recessed portion 1141 may be adapted to the outer shape of the driving motor 311 . For example, the recessed portion 1141 may form an arc-shaped structure, and an arc-shaped protrusion corresponding to the recessed portion 1141 is formed on the second side 102 of the housing 11 .

[0083] In the above technical solution, by setting the recessed portion 1141, on the one hand, the recessed portion 1141 can be used to position the drive motor 311 to ensure the positioning and installation of the drive motor 311, and on the other hand, a height difference can be formed between the recessed portion 1141 and the installation position of the reduction mechanism 312, so that the wire hole 1142 can be formed conveniently, so that the wire of the drive motor 311 can be more easily passed through the shell 11 to be electrically connected to the circuit board located on the second side 102 without the need for excessive winding.

[0084] In addition, a protruding structure corresponding to the recessed portion 1141 is formed on the second side 102 of the shell 11 , which can facilitate the molding of the shell 11 while ensuring the structural strength of the shell 11 and will not affect the installation of the circuit board.

[0085] Generally speaking, since the thickness of the battery 60 is greater than the thickness of the circuit board, a larger space needs to be reserved for the battery 60 to be installed. Figure 4 and Fig.14 As shown, in some examples, the circuit board is disposed in the first receiving groove 114 , the battery 60 is disposed in the second receiving groove 115 , and the depth H2 of the second receiving groove 115 is greater than the depth H1 of the first receiving groove 114 .

[0086] In addition, since the circuit board and the drive motor 311 are arranged relative to each other in the thickness direction of the shell 11, the thickness of the circuit board is smaller, and therefore the depth of the first accommodating groove 114 is set to be greater than the depth of the first accommodating groove 114, a larger installation space 110 can be reserved for the drive motor 311 on the first side 101 of the shell 11.

[0087] like Figure 4 As shown, in some embodiments, the battery 60 is disposed in the second receiving groove 115, and a first stopper is disposed in the second receiving groove 115 for limiting the position of the battery 60. The first stopper can limit the battery 60 in the second receiving groove 115 to prevent the battery 60 from shaking in the second receiving groove 115.

[0088] Among them, the first accommodating groove 114 and the second accommodating groove 115 are separated by the isolation plate 113, that is, the circuit board and the battery 60 are separated by the isolation plate 113, and the first limiting member includes a limiting protrusion 116, and the limiting protrusion 116 and the isolation plate 113 are spaced apart in the width direction of the shell 11, and the battery 60 is limited between the limiting protrusion 116 and the isolation plate 113.

[0089] In the above technical solution, the battery 60 can be fixed in the second receiving groove 115 by the cooperation between the limiting protrusion 116 and the isolation plate 113, thereby ensuring the installation reliability and stability of the battery 60.

[0090] In some examples, the side of the limiting protrusion 116 facing the isolation plate 113 has a curved surface 1161 adapted to the outer surface of the battery 60. The curved surface 1161 of the limiting protrusion 116 is adapted to the contour of the battery 60, which can better position the battery 60 without causing damage to the battery 60.

[0091] like Fig. 9 ,like Fig.13 and Fig.14As shown, in some embodiments, the massage movement 100 also includes a cover plate 13, which covers the openings of the first receiving groove 114 and the second receiving groove 115, and the cover plate 13 is connected to the shell 11 to enclose one of the circuit board and the battery 60 in the first receiving groove 114 and the other of the circuit board and the battery 60 in the second receiving groove 115.

[0092] Therefore, by setting the cover 13, not only can the circuit board and the battery 60 be respectively enclosed in the first accommodating groove 114 and the second accommodating groove 115, thereby limiting and protecting the circuit board and the battery 60 to prevent damage, but on the other hand, it can ensure that the appearance of the massage movement 100 is flat and compact.

[0093] like Figure 5 , Figure 7-10 As shown, according to some embodiments of the utility model, the installation space 110 has two first installation grooves 1101 and a second installation groove 1105, the two first installation grooves 1101 are arranged in the length direction of the shell 11, the second installation groove 1105 is located between the two first installation grooves 1101, the number of massage components 20 is two, and the two massage components 20 are respectively arranged in the two first installation grooves 1101, and the driving device 30 is arranged in the second installation groove 1105.

[0094] That is to say, the driving device 30 is located between the two massage components 20. This arrangement makes it convenient to use the same driving device 30 to drive the two massage components 20 at the same time, so that the two massage components 20 can be used in conjunction with each other to form a kneading-like movement form, thereby improving the massage effect and thus improving the user experience.

[0095] In addition, the two massage components 20 and the driving device 30 are arranged in the length direction of the housing 11, which effectively utilizes the space of the housing 11 in the length direction and improves space utilization.

[0096] like Figure 5 As shown, in some embodiments, the shell 11 includes two partition plates 117, the two partition plates 117 are arranged in the installation space 110, and the two partition plates 117 are arranged opposite to each other in the length direction of the bottom wall 111, and a second installation groove 1105 is defined between the bottom wall 111, the peripheral wall 112 and the two partition plates 117, and a first installation groove 1101 is defined between the bottom wall 111, the peripheral wall 112 and each partition plate 117.

[0097] The partition plate 117 can be integrally formed with the bottom wall 111 and the peripheral wall 112 of the housing 11 to ensure the structural strength of the housing 11. Of course, the partition plate 117 can also be formed separately and connected to the bottom wall 111 and the peripheral wall 112 of the housing 11 by mechanical connection.

[0098] In the above technical solution, two partition plates 117 are provided, and the installation space 110 surrounded by the bottom wall 111 and the peripheral wall 112 can be partitioned by using the two partition plates 117, thereby dividing two first installation grooves 1101 and one second installation groove 1105, so that the massage component 20 and the drive device 30 can be arranged in partitions and used in coordination, so that the massage movement 100 can form a kneading-like movement form to meet the use requirements.

[0099] like Figure 5 and Fig.14 As shown, in some examples, a side of the partition plate 117 away from the bottom wall 111 is provided with an avoidance notch 1171 for avoiding the output shaft 32 of the driving device 30 so that the output shaft 32 of the driving device 30 is connected to the massage assembly 20 .

[0100] In the above technical solution, by setting the avoidance notch 1171, on the one hand, the output shaft 32 of the driving device 30 can be limited, and on the other hand, the output shaft 32 of the driving device 30 and the massage component 20 can be effectively avoided to prevent interference.

[0101] like Fig.14 As shown, in some specific examples, the dimension of the avoidance gap 1171 in the thickness direction of the shell 11 is h1, the maximum dimension of the partition plate 117 in the thickness direction of the shell 11 is h, and h1 / h is 1 / 4-3 / 4.

[0102] Specifically, the dimension h1 of the avoidance gap 1171 in the thickness direction of the housing 11 may be (1 / 4, 3 / 8, 1 / 2, 5 / 8, 3 / 4) h. The avoidance gap 1171 may be formed as a semicircular gap. Of course, the avoidance gap 1171 may also be formed in other shapes.

[0103] Therefore, by limiting the size of the avoidance gap 1171, the massage component 20 and the drive device 30 can be effectively avoided to prevent the partition plate 117 from interfering with the massage component 20, the drive device 30 and other structures, thereby ensuring that the massage component 20 can work normally.

[0104] like Fig.13 and Fig.14 As shown, in some examples, the driving device 30 includes a driving motor 311 and a reduction mechanism 312, the driving motor 311 is connected to the reduction mechanism 312, the output shaft 32 of the reduction mechanism 312 is connected to the massage component 20, and the reduction mechanism 312 can reduce the rotation speed of the motor shaft of the driving motor 311, so that the movement speed of the massage component 20 can meet the requirements.

[0105] The driving motor 311 and the speed reduction mechanism 312 are arranged in the width direction of the housing 11 , and the height of the partition plate 117 at the driving motor 311 is greater than the height of the partition plate 117 at the speed reduction mechanism 312 .

[0106] Specifically, Fig.14 As shown, the partition plate 117 includes a first plate portion 1172 and a second plate portion 1173, and the first plate portion 1172 and the second plate portion 1173 are arranged in the width direction of the shell 11, the first plate portion 1172 corresponds to the position of the drive motor 311, and the second plate portion 1173 corresponds to the position of the speed reduction mechanism 312, and the height h of the first plate portion 1172 is greater than the height h2 of the second plate portion 1173, that is, the size of the first plate portion 1172 in the thickness direction of the shell 11 is greater than the size of the second plate portion 1173 in the thickness direction of the shell 11.

[0107] In the above technical solution, by setting the height of the partition plate 117 at the drive motor 311 to be greater than the height of the partition plate 117 at the speed reduction mechanism 312, the higher portion of the partition plate 117 at the drive motor 311 can be connected to the cover body 12, and the cover body 12 is matched with the shell 11, so that the speed reduction mechanism 312 and the drive motor 311 are installed in a relatively closed space to form protection.

[0108] In addition, since the speed reduction mechanism 312 is connected to the massage component 20 , the height of the partition plate 117 at the speed reduction mechanism 312 is set lower, so that the partition plate 117 can effectively avoid the massage component 20 and avoid interference between the partition plate 117 and the massage component 20 .

[0109] In some examples, the massage movement 100 further includes a cover 12 , which covers the opening of the second mounting groove 1105 , is abutted against the two partition plates 117 , and is connected to the driving device 30 to enclose the driving device 30 in the second mounting groove 1105 .

[0110] Specifically, the portion of the partition plate 117 at the drive motor 311 abuts against the cover body 12, that is, the first plate portion 1172 of the partition plate 117 can abut against the cover body 12, and the portion of the partition plate 117 at the reduction mechanism 312 is separated from the cover body 12, that is, the second plate portion 1173 of the partition plate 117 is separated from the cover body 12, so that the portion of the cover body 12 at the drive motor 311 can abut against the partition plate 117, and the portion of the cover body 12 at the reduction mechanism 312 abuts against and is connected to the reduction mechanism 312, thereby covering the drive motor 311 and the reduction mechanism 312 with the cover body 12.

[0111] In the above technical solution, the cover 12 acts as a top shell provided on the shell 11, which can cover the driving device 30, which is more conducive to miniaturization, and the cover 12 does not interfere with the space where the massage component 20 is located, ensuring that the massage component 20 can move normally.

[0112] like Figure 15-19 As shown, in some embodiments, a mounting seat 41 is disposed in the first mounting groove 1101 , a second limiting member 42 is disposed on the mounting seat 41 , and a limiting cavity 401 is defined between the second limiting member 42 and the mounting seat 41 .

The rocker arm 231 is driven by the driving device 30 and supported by the supporting portion 23111, and moves circumferentially around the driving axis of the driving device 30.

[0114] Therefore, by arranging the mounting seat 41 and the second limiting member 42 in the first mounting groove 1101, a limiting cavity 401 for mounting the support portion 23111 can be defined, and the support portion 23111 can be given a degree of freedom, thereby limiting the movement of the massage component 20.

[0115] In some examples, the support portion 23111 is a spherical structure, and the second stopper 42 and the mounting seat 41 respectively have a matching spherical surface that matches the shape of the support portion 23111. In this way, the support portion 23111 can rotate in the stopper cavity 401, thereby constraining the massage component 20 and ensuring that the massage component 20 can meet the set movement form.

The eccentric wheel 21 has a curved surface 211 on the side facing the driving body 31, and the eccentric wheel 21 also has a driving inclined surface, and the crank component 22 abuts against the driving inclined surface. The driving inclined surface is used to drive the crank component 22 to swing in the first direction when the eccentric wheel 21 rotates.

The first rod segment 2311 includes a supporting portion 23111, a spacer 23112, a limiting step 23113 and a limiting portion 23114. The supporting portion 23111 and the limiting portion 23114 are located at one end of the first rod segment 2311. The spacer 23112 is connected between the supporting portion 23111 and the limiting step 23113. The second rod segment 2312 is a metal rod.

[0138] When the driving device 30 is working, the two eccentric wheels 21 can be driven to rotate through the output shaft 32. Since each eccentric wheel 21 is connected to the corresponding swing rod 231, the two swing rods 231 can perform circumferential swinging motion around their respective supporting parts 23111 under the drive of the corresponding eccentric wheel 21, so that the swing rod 231 can drive the second massage piece 232 thereon to perform circumferential swinging motion, and the two eccentric wheels 21 can respectively drive the corresponding crank component 22 to move. Since the first massage piece 24 is connected to both the crank component 22 and the second massage piece 232, the first massage piece 24 can move under the drive of the corresponding crank component 22 and the swing rod 231. In other words, the eccentric wheel 21 can drive both the swing rod 231 and the crank component 22, so that the first massage piece 24 and the second massage piece 232 are driven to move along a predetermined trajectory through the joint action of the crank component 22 and the swing rod 231.

[0139] In this embodiment, the two massage components 20 are symmetrically arranged about the central plane of the massage movement 100 that is perpendicular to the length direction. The movement of the first massage piece 24 in one of the two massage components 20 is mirror-symmetrical with the movement of the first massage piece 24 in the other of the other massage components 20 about the central plane of the massage movement 100. The movement of the second massage piece 232 in one of the two massage components 20 is mirror-symmetrical with the movement of the second massage piece 232 in the other of the other massage components 20 about the central plane of the massage movement 100, thereby forming a kneading-like movement form to achieve the set massage effect and meet the usage requirements.

When the eccentric wheel 21 is running, even if a finger is inserted into the gap 210 between the curved surface 211 and the side wall of the first mounting groove 1101, as the eccentric wheel 21 rotates, the curved surface 211 can smoothly push the finger out, further reducing the probability of pinching the finger.
