Description

Technical Field

[0001] The invention relates to the technical field of massage devices, in particular to a massage movement which can move and adjust the angle. Background Art

[0002] Massage is a method of physical therapy that uses the theory of viscera and meridians in traditional Chinese medicine as its theoretical basis, combined with the anatomy and pathological diagnosis of Western medicine, to act on specific parts of the human body surface to regulate the body's physiological and pathological conditions. In order to relieve physical fatigue or for health purposes, there are many massage devices on the market that can massage various parts of the human body. With the development of science and technology, the instruments for massaging the human body are becoming more and more diversified. The functions and structures of massagers are different for different parts and acupoints of the human body. For example, a neck massager realizes the massage function by utilizing the dynamic operation of an electric massage movement.

[0003] There are many types of neck massagers at present, but for most neck massagers, the head unit is fixed, and massages of different strengths are achieved by designing the shape of the massage head. To address this problem, Chinese Patent Application No. 202210301328.1 discloses a massager, a massager comprising: a massage mechanism, the massage mechanism comprising a rotating drive member and a massage head, the rotating drive member is connected to the massage head and drives the massage head to rotate; a travel drive mechanism, the travel drive mechanism comprises an output shaft; a transmission mechanism, the transmission mechanism comprises a screw connected to the output shaft, the rotating drive member is threadedly connected to the screw, the travel drive mechanism drives the screw to rotate through the output shaft, and then drives the massage head to reciprocate along the screw. The above-mentioned massager can drive the screw to rotate through the travel drive mechanism. Since the rotating drive member is threadedly connected to the screw, the rotating drive member can be driven to move in a straight line along the screw when the screw rotates, thereby realizing the reciprocating movement of the massage head connected to the rotating drive member along a straight line, and the operation process has low noise.

[0004] This patent enables the massage head to move within a certain range, but the walking structure is complex. Although the noise can be reduced a little by converting the rotational motion into linear movement, the rotational drive component of the massage mechanism and the walking drive mechanism itself will generate relatively large noise. The meshing of the teeth using the screw drive will also generate relatively large noise. At the same time, due to its own design problems, it is impossible for the first shell and / or the second shell to rotate at an angle.

[0038] The following will be combined with the attached embodiment of the present invention Figure 1-12, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0039] like Figures 1 to 12 As shown, this embodiment discloses a massage movement that can move and adjust the angle. This solution is aimed at improving the massager used on the cervical spine, solving the existing problems of insufficient massage, inability to adapt to the neck sizes of different people, and poor applicability. The detailed design scheme of this product is as follows:

[0040] It includes a shell 103, a drive component 100 and power components 101 and 102. The drive component 100 is installed on the shell, and the power components 101 and 102 are arranged on both sides of the shell. This solution preferably adopts a symmetrical structure for design, but is not limited to this. The symmetrical design has consistent massage position and strength, and the massage experience effect is better.

[0041] The shell 103 is divided into an upper shell 1032 and a lower shell 1031. The upper shell 1032 and the lower shell 1031 are connected by fasteners, and an inner cavity is formed between the two. The fasteners of this solution are fixed by screws or bolts.

[0042] The driving assembly 100 includes a motor 1001 and a gear set installed in the inner cavity. The gear set is connected to the motor 1001 in a transmission manner. The gear set includes driving gears 107, 108 and a driven gear 109. The driving gears 107, 108 are meshed with the output shaft of the motor 1001. The driving gears are driven to rotate by the power output of the motor to achieve a transmission connection between the two. The circumferential surface of the driven gear 109 is provided with driven teeth 1091 and a driving shaft 1092. This scheme is preferred. The three are integrally processed to improve the stability and reliability of the product. The driven gear is meshed and connected to the driving gears 107, 108 through its driven teeth 1091. The driving shaft 1092 swings with the driven gear. Among them, the two driving gears 107, 108 are connected and meshed. The meshing line of the two driving gears 107, 108 is the center. The two driven gears 109 are designed on both sides of the driving gears 107, 108 respectively. This scheme gives priority to symmetrical design for the purpose of synchronization of action.

[0043] The power components 101 and 102 include a sliding component, a connecting rod 104, a rotating drive component and a massage component 106 connected to the rotating drive component. The rotating drive component adopts a motor. The massage component 106 is composed of a plurality of massage heads and a massage head seat. The massage head seat is installed on the motor output shaft. The massage heads can be the same or different. The rotating drive component and the massage component are both installed on the sliding component. The driving shaft 1092 is connected to one end of the connecting rod 104. Specifically, a cylindrical shaft 1093 is processed under the driving shaft 1092, and the corresponding connecting rod 104 is opened with a connecting movable hole. One end of the connecting rod 104 is connected to the sliding component, and the sliding component swings through the connecting rod to drive the rotating drive component to move.

[0044] The sliding assembly includes a sliding cover 1021 and a motor movable bracket 107. A sliding rail 1023 is opened in the sliding cover 1021. The motor movable bracket 107 is provided with a sliding block 1072 adapted to slide on the sliding rail facing the direction of the sliding rail. The sliding block 1072 can move back and forth in the direction of the sliding rail under the action of external force to realize the walking function. The motor movable bracket has a mounting seat 1075 for installing a rotating drive component.

[0045] The walking scheme of this scheme is more reasonable. It uses sliding to walk. Specifically, the rotating drive part slides on the sliding assembly, and the connecting rod pulls the rotating drive part to move as a whole to achieve movement on the sliding assembly. The result is simpler and there is no complicated transmission structure. The movement is driven by the connecting rod, which reduces the current noise problem of the transmission mechanism.

[0046] There are two driving gears 107 and 108, which are arranged side by side and meshed with each other. There are two driven gears, and the driven teeth of the two driven gears are respectively meshed with the two driving gears. One of the driving gears is connected to the motor output shaft, and both driving gears can be connected to the motor output shaft. If two driving gears are connected to the motor output shaft, it is necessary to design a transition transmission for the motor output shaft, which is divided into two output shaft transmissions, and a gear structure can also be used.

[0047] The sliding cover has a sliding cover storage cavity, the inner wall of which is processed with an upper horizontal plate 1024 and a lower horizontal plate 1023, the upper horizontal plate 1024 and the lower horizontal plate 1023 are arranged opposite to each other, forming a sliding channel 1025 as a sliding rail, the upper horizontal plate and the lower horizontal plate are both processed with a limit side plate 1026, the cross section is L-shaped, the sliding block 1072 of the motor movable bracket is processed with an upper limit sliding block 1073 and a lower limit sliding block 1074, the cross section is T-shaped, the upper limit sliding block is placed at the upper horizontal plate in the direction of the sliding channel, and the lower limit sliding block is placed at the lower horizontal plate in the direction of the sliding channel.

[0048] This solution can ensure that the vertical direction of the motor movable bracket is restricted so that it can only move along the direction of the sliding channel, ensuring the feasibility and reliability of its walking.

[0049] The motor movable bracket is also processed with a convex shaft 1071, on which a bearing 112 is installed. One end 1041 of the connecting rod is sleeved outside the bearing and connected. The end of the connecting rod is processed to fit the outer peripheral surface of the bearing.

[0050] The sliding cover 1021 is movably connected to the shell. Under the action of external force, the sliding cover 1021 can be adjusted relative to the shell to form an angle-adjustable structure. This solution can realize that the sliding covers located on both sides of the shell can rotate relative to the shell. This structure combined with the walking structure can ensure the reliability of massage, so that it can be attached to the neck for massage, and can also meet the massage needs of people of different physiques. If the distance between the two massage heads decreases during walking, the angle adjustment of this solution can appropriately expand the two sliding covers outward, which will not cause pressure on the neck of the person, but can be tightly attached to the neck, making the massage more comfortable and reasonable.

[0051] The sliding cover has a corner, on which an upper movable shaft 1027 and a lower movable shaft 1028 are processed. The upper shell has an upper movable hole 1033 adapted to the upper movable shaft, and the lower shell has a lower movable hole 1036 adapted to the lower movable shaft. When installed, the upper movable shaft 1027 is in the upper movable hole 1033, and the lower movable shaft 1028 is in the lower movable hole 1036, forming the upper movable shaft 1027 and the lower movable shaft 1028 as a rotation fulcrum. The upper shell and / or the lower shell are provided with a convex column 1038, and a torsion spring 113 is installed on the convex column 1038. One end 1131 of the torsion spring is stuck in the corner of the sliding cover, specifically between the upper movable shaft 1027 and the lower movable shaft 1028. Reinforcement columns 1035 and 1037 are added on both sides of the upper movable hole 1033 and the lower movable hole 1036 to improve the firmness of rotation, and are also used for limiting to prevent the sliding cover from rotating too much.

[0052] This solution utilizes a torsion spring to provide a rebound force to ensure that the two sliding covers have a force to be retracted inward when the two sliding covers are opened outward in opposite directions.

[0053] The sliding cover 1021 is provided with a sliding cover support 1029, and the sliding cover support 1029 is provided with a first connecting end 10291 with an inner cavity; the upper shell is provided with an upper shell support 1034, and the upper shell support 1034 is provided with a second connecting end 1035 with an inner cavity, and an elastic member 105 is provided between the first connecting end and the second connecting end, and the two ends of the elastic member are respectively arranged at the first connecting end 10291 and the second connecting end 1035, when the sliding cover rotates, the elastic member is in a compressed state as the sliding cover support and the upper shell support move toward each other, and the elastic member adopts a compression spring.

[0054] The present solution further provides a rebound force when the two sliding covers are opened outward in opposite directions. Because when the two sliding covers are opened outward in opposite directions, the distance between the first connecting end and the second connecting end is reduced, and the compression spring will be compressed at this time, that is, an elastic force that needs to be restored to its original state is generated, so that the massage head on the sliding cover can be attached to the human neck, and the massage effect is better. The present solution combines the walking structure and the structure of the torsion spring, so that the massage head can walk and adjust the angles of the two sliding covers accordingly, thereby realizing the two linkage functions of walking and angle, so that the neck will not be compressed during the walking process to make the consumer uncomfortable, and there will be no problem of inadequate massage. The design is very reasonable and reliable.

[0055] Two groups of limit switches are installed on the upper shell and / or the lower shell. Each group of limit switches is divided into an upper limit switch 111 and a lower limit switch 110. The upper limit switch and the lower limit switch are distributed in the moving direction of the driving shaft of the driven gear to limit the swing range of the driving shaft.

[0056] The motion trajectory of this scheme can be referred to Fig.10 As shown, the moving direction of the sliding cover 1021 is inward direction C or outward direction D. The direction is based on the swinging direction of the driving shaft driven by the rotation of the motor. The direction of the angle adjustment is inward contraction, as shown in direction B. The sliding covers move towards each other and expand outward as shown in the direction of Figure A, that is, the sliding cover moves in the direction.

[0057] The invention also includes an explosion-proof opening structure suitable for preventing the hinged sliding cover and the housing from separating, and the explosion-proof opening structure includes:

[0058] At least one stopper 1 is arranged at the outer edge of the upper shell, and a receiving cavity is formed between the stopper 1 and the upper shell, and the receiving cavity has a side contact surface 11 and an upper contact surface 12, and the upper contact surface 12 is formed on the lower end surface of the stopper;

[0059] The plug-in area 2 is formed on the outer edge of the sliding cover and can be adapted to the receiving cavity. The side end surface 21 of the plug-in area 2 can contact with the side contact surface 11 during the movement process to achieve a limiting effect.

[0060] The main purpose of this solution is to prevent the sliding cover and the shell that are hinged to each other from separating. The design structure of this solution is simple and the service life is extended. It should be pointed out that the block 1 is a triangular structure, the force at the hinge is large, and the block area close to the hinge is large, which can increase its firmness to prevent cracking and increase the contact surface to prevent the two from separating. This solution mainly combines the angle adjustment of the sliding cover and the shell to ensure that there is also a resistance area on the outside in the rotation direction to prevent separation.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
