Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] The utility model provides a shoulder and neck massager, combined with Figures 1 to 8The shoulder and neck massager comprises a housing 10 , a driving member 20 , two transmission components 40 , two eccentric components, a kneading component and two knocking components 30 .

[0039] The housing 10 is provided with two symmetrically arranged limiting holes 11;

[0040] The driving member 20 is installed in the housing 10;

[0041] Two transmission assemblies 40, the two transmission assemblies 40 are respectively drivingly connected to the driving member 20;

[0042] A kneading assembly, the kneading assembly is connected to one of the transmission assemblies 40;

[0043] Two eccentric components, the two eccentric components are respectively connected to the two ends of another transmission component 40; each eccentric component includes an eccentric crank 43 and a connecting rod 44, the axis of the connecting rod 44 extending in the direction of the eccentric crank 43 extending in the direction of the eccentric crank 43 is arranged at an angle, one end of each eccentric crank 43 is connected to a transmission component 40, and the other end is connected to the connecting rod 44; and

[0044] Two striking assemblies 30, each striking assembly 30 is rotatably connected to a connecting rod 44;

[0045] The driving member 20 simultaneously drives the two transmission components 40 to rotate, so as to drive the kneading components to perform kneading actions. Under the drive of the driving member 20, the eccentric component 43 drives each striking component 30 to perform linear reciprocating motion in each limiting hole 11 to achieve striking.

[0046] The shoulder and neck massager proposed in the technical solution of the utility model includes a shell 10, which is an elliptical structure with a hollow interior, and is mainly used to install and protect other internal components such as a driving member 20 and two transmission components 40, so that these components can work together, and at the same time, the shell 10 can withstand external impact and pressure. Two limiting holes 11 are provided on the shell 10. The two limiting holes are mainly used to install and position the knocking component 30 to ensure that the knocking component 30 works at the correct position.

[0047] The driving member 20 is an important component installed inside the housing 10 , and mainly includes a motor, a driving shaft, etc. The motor is the power source for driving the entire massage mechanism, and the driving shaft transmits the power of the motor to the transmission assembly 40 .

[0048] The two transmission assemblies 40 are driven by the driving member 20 respectively, and one of the transmission assemblies drives the kneading assembly to move. The kneading assembly is an important assembly connected to the transmission rod of the other transmission assembly. Its main function is to knead the shoulders and neck. The other group of transmission assemblies drives the eccentric assembly to move, and the driving member 20 drives the two transmission assemblies 40 to rotate at the same time, thereby driving the kneading assembly and each eccentric assembly to perform rotational movement. In this process, the shoulders are kneaded and tapped at the same time, which not only increases the comfort of use, but also can more effectively relax and relieve the tense muscles in the shoulders and neck, and will not significantly increase the weight of the whole machine, and will not cause additional burden on use.

[0049] Two eccentric components are connected at both ends of the transmission component 40. This connection method allows the two eccentric components to work together to achieve a specific motion effect. Each eccentric component includes an eccentric crank 43 and a connecting rod 44. The axis of the connecting rod extending direction is set at an angle with the axis of the eccentric crank extending direction. One end of the connecting rod is rotatably connected to the end of the eccentric crank away from the transmission rod. The transmission rod drives the eccentric crank to rotate, and the eccentric crank drives the connecting rod to move, thereby realizing the reciprocating motion trajectory of the knocking component in the slide rail.

[0050] One end of the eccentric crank 43 is connected to the transmission assembly 40, and the other end is connected to the connecting rod 44. This connection mode allows the eccentric crank 43 to rotate around the transmission assembly 40, while further driving the connecting rod 44 to rotate. This movement mode allows the entire mechanism to achieve a more complex movement effect.

[0051] The two newly added knocking assemblies 30 are movably connected to an eccentric assembly. Their main function is to knock the deltoid muscle of the shoulder during the rotation of the connecting rod assembly, and they form a 90° angle with the deltoid muscle of the shoulder, so as to provide a better hammering experience.

[0052] Please refer to Figure 4In one embodiment of the present application, each eccentric assembly adopts a structure in which an eccentric crank 43 and a connecting rod 44 are connected, which can provide an accurate and stable motion mode. Each connecting rod 44 is connected to an eccentric crank 43, and the axis of the connecting rod 44 extending in the direction of the eccentric crank 43 is set at an angle. This angle setting can make the eccentric crank 43 change the direction of the connecting rod 44, and the connecting rod 44 is driven to rotate in the vertical direction through the rotation of the eccentric crank 43. The other end is connected to the striking assembly 30 by a rotating connection. This connection method enables the eccentric assembly to drive the striking assembly 30 to reciprocate in the limiting hole 11. The eccentricity of the eccentric crank 43 is 3-25mm. If the eccentricity is too large, the noise is large and the transmission efficiency is low; the eccentricity setting of the eccentric crank 43 can keep the equipment stable during operation and reduce unnecessary vibration and noise. The striking assembly 30 can reciprocate in the limiting hole 11 through the drive of the eccentric crank 43.

[0053] In this embodiment, the connecting rod 44 is used to connect and transmit power. The connecting rod 44 includes two parts with a turning arrangement, each of which has a turning hole, and the two parts are parallel but not in the same plane, and the two parts are connected together as a whole. In the arrangement of the connecting rod 44, the turning part is used to change the direction or path of the connecting rod to avoid interference between the eccentric crank 43 and the connecting rod 44 during the rotation process.

[0054] The eccentric crank 43 is also used to change the direction or torque of the transmission. It also includes two parts of a turning arrangement, one of which is rotatably connected to the above-mentioned rotating hole, and the rotating hole allows them to rotate relative to each other within 360 degrees. The other part is fixedly connected to the transmission assembly 40 to avoid interference between the eccentric crank 43 and the connecting rod 44 during the rotation process. This connection method also allows the connecting rod 44 and the eccentric crank 43 to flexibly adapt to the mechanical movement requirements while maintaining their stability.

[0055] Please refer to Figure 1 In one embodiment, the two transmission components include a first gear 23, at least two second gears 24, at least two third gears 41 and two transmission rods 42. The driving member is installed in the housing 10 through a bracket 26, and the bracket 26 provides a stable support for the entire driving assembly. The driving member is arranged on the bracket 26, which can be specifically configured as an electric motor or a pneumatic motor, etc., for generating driving power.

[0056] Furthermore, the motor is provided with a driving shaft 22, which meshes with the first gear 23. When the motor is started, the driving shaft 22 drives the first gear 23 to rotate. The power of this rotation is transmitted to at least two second gears 24 through the first gear 23, causing them to rotate.

[0057] In this embodiment, each second gear 24 is meshed with at least one third gear 41. When the second gear 24 is driven to rotate, it drives the third gear 41 connected thereto to rotate. In this way, through the mutual cooperation between the various parts of the driving member 20, the third gear 41 can receive and transmit the power from the motor, thereby completing the operation of the entire system. This structure has the advantages of high efficiency, compact structure, and easy maintenance. At the same time, by using a multi-stage gear transmission, the driving power can be effectively transmitted to each third gear 41, making the operation of the entire system more stable and reliable. The two third gears 41 are respectively sleeved on two transmission rods 42, and one transmission rod 42 drives the kneading assembly to move. This connection method enables the kneading assembly to achieve continuous reciprocating motion through the drive of the transmission rod, and the other transmission rod 42 drives the eccentric crank 43 installed at both ends to move. This connection method enables the eccentric crank 43 to achieve continuous rotational motion through the drive of the transmission rod 42.

[0058] Please refer to Figure 7 In one embodiment, each third gear 41 in each transmission assembly is provided with a one-way bearing 411, which enables the connecting rod assembly 40 to have better transmission performance and higher stability. In addition, the one-way bearings 411 in the two groups of connecting rod assemblies 40 rotate in opposite directions, which can be the movement of the knocking assembly or the rotation of the original shoulder and neck massage assembly when the motor rotates clockwise, that is, the motor rotates forward and reverse, respectively driving one group of connecting rod assemblies to move; one or two one-way bearings can also be eliminated to make both move at the same time; this can increase the stability and reliability of the transmission process and reduce errors caused by external interference.

[0059] In this embodiment, a transmission assembly 40 is added on the basis of the existing driving member 20 to realize the knocking function. The newly added connecting rod assembly and the original connecting rod assembly each add a one-way bearing 411, and the rotation directions of the two are opposite. This solution can realize the newly added knocking function without increasing the specifications and quantity of the motors, and can reduce the cost and product weight.

[0060] Please refer to Figure 6 In this embodiment, the driving assembly also includes at least two first bearings 25, which are respectively fixedly connected to the housing and are arranged at both ends of the driving member and the transmission rod 42, so as to provide precise positioning for the transmission rod 42, and withstand various dynamic and static loads generated by the transmission assembly during operation, reduce the vibration caused by the excessive length of the transmission rod 42, reduce noise, and can effectively reduce friction loss, improve transmission efficiency, and ensure that the transmission member can operate stably.

[0061] Please refer to Figure 5In one embodiment, one of the transmission components further includes at least two couplings 46 and two second bearings 47, and one end of the coupling 46 is sleeved on one end of the transmission rod 42. At the same time, the other end of the coupling 46 is connected to the eccentric crank 43, forming a stable structure that fixes the eccentric crank 43 to the rotating member 42. The coupling can also eliminate the assembly error between the two and reduce noise.

[0062] Furthermore, the second bearings 47 are respectively arranged at both ends of the transmission rod 42 and are spaced apart from the coupling and fixedly connected in the housing. The second bearings 47 not only increase the stability of the transmission rod 42, but also effectively reduce friction and wear.

[0063] In this embodiment, the coupling 46 and the second bearing 47 can effectively connect the eccentric crank 43 with the transmission rod 42, and maintain a stable operating state during the rotation process. At the same time, the coupling 46 and the second bearing 47 are used in combination, and the coupling is 0-30 mm away from the knocking component, and the first bearing (one, two or more) is added to support, so as to prevent the drive shaft from swinging too long and generating a large noise, that is, the vibration caused by the excessive length of the transmission rod 42 can be reduced, and the noise can be reduced, so that the transmission component has lower noise and longer service life.

[0064] Please refer to Figure 2 In one embodiment, the striking assembly 30 performs its functions through its components, realizes connection with the transmission assembly 40 and performs sliding striking under the drive of the transmission assembly 40.

[0065] Specifically, the striking assembly 30 includes a support member 31, a striking member 32 and a slide rail 33. One end of the support member 31 is connected to a connecting member in the transmission assembly 40 in a detachable manner, and then connected to a connecting rod 44, thereby forming a stable supporting structure, so that the striking member 32 can slide under the drive of the transmission assembly 40.

[0066] The slide rail 33 is installed on the inner side of the limiting hole 11, and its existence provides a directional movement path for the striking member 32. The striking member 32 can only slide on a specific track, thereby ensuring the stability and accuracy of the striking action.

[0067] Furthermore, the striking member 32 is detachably connected to the other end of the support member 31 and can slide along the slide rail 33 under the drive of the connecting rod assembly, so that the striking member 32 can be disassembled, reinstalled and replaced according to actual needs, increasing the flexibility and convenience of use. At the same time, under the drive of the transmission assembly 40, the striking member 32 can slide in the slide rail 33 to complete the striking action.

[0068] In this embodiment, the angle between the center line of the striking member 32 and the slide rail 33 and the connecting line of the driving shaft center and a rotation center of the connecting rod is between 0-20 degrees to reduce torque loss and increase transmission efficiency.

[0069] Please refer to Figure 4 In one embodiment, the connecting rod assembly further comprises two connecting members 45, one end of each connecting member is rotatably connected to one end of each connecting rod 44 away from the transmission rod 42, and the other end is detachably connected to the support member 31, which makes it flexible. The function of the connecting member 45 in the striking assembly is to provide a rotatable connection mode. In addition, the connecting member 45 can also position and fix the striking assembly to ensure the stability and accuracy of the connecting rod assembly.

[0070] Furthermore, the connecting member 45 is specifically configured as a cylindrical connecting seat, through which the connecting rod is connected at the bottom, and the supporting member is connected at the top to support the striking member to perform linear reciprocating motion under the transmission of the connecting rod, that is, the driving shaft drives the eccentric crank 43 and then drives the connecting rod 44 to perform linear reciprocating motion; the striking assembly can also be additionally supported and strengthened to improve the overall performance and durability of the connecting rod assembly and the striking assembly.

[0071] Please refer to Figure 2 In one embodiment, a vibration damper 34 is provided between the slide rail 33 and the stop hole 11. The vibration damper can effectively absorb and buffer the impact and vibration caused by movement to protect the stability and durability of the entire structure. Its presence can reduce the vibration and noise caused by friction or other forms of movement between the slide rail 33 and the stop hole 11, thereby improving the overall performance.

[0072] Furthermore, the vibration damper 34 can also optimize the connection mode. By reasonably setting the structure and material of the vibration damper, the shock and vibration generated during the movement can be better absorbed and dispersed, thereby further improving the overall performance. At the same time, the vibration damper can also provide a certain buffering effect to reduce the impact on the entire structure that may be caused by external impact.

[0073] In this embodiment, the vibration damping member 34 can be made of materials with good buffering and vibration damping properties, such as silicone, soft glue, rubber or polyurethane. These materials can effectively reduce vibration, reduce noise, and absorb and disperse the impact and vibration generated during the movement, thereby further improving the overall performance. At the same time, the vibration damping member 34 can also be set to a structure with different shapes and sizes according to actual needs to meet the needs of different structures.

[0074] Please refer to Figure 8In one embodiment, the kneading assembly includes a first kneading part 50 and a second kneading part 60, and the first kneading part 50 and the second kneading part 60 are arranged at an angle to the axis of a transmission assembly. Through this unique angle setting, the shoulder and neck massager can massage in a more precise and diverse manner, making the massage force more uniform and comfortable. When using it, the user can feel the all-round and three-dimensional massage effect, effectively relieve muscle tension and fatigue, and bring a more pleasant and relaxing massage experience.

[0075] In this embodiment, the angle between the knocking assembly and the second kneading component 60 can be specifically set to 50±25°, which can ensure that the knocking and kneading actions are offset in space to a certain extent, so that a larger massage area can be covered, making the massage effect more comprehensive. Secondly, this structure can avoid muscle fatigue caused by over-concentrated massage actions, and help provide a more lasting and comfortable massage experience.

[0076] Furthermore, the newly added striking assembly forms a 90° angle with the deltoid muscle of the shoulder, which makes the striking experience better. This setting is also conducive to improving the stability of the device. Since the striking assembly and the kneading assembly are connected by a connecting rod assembly, these components can maintain a relatively stable position relationship even at high speeds, thereby providing more reliable performance.

[0077] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
