Description

Technical field:

[0001] The utility model relates to the technical field of massagers, in particular to a swing mechanism of a massage device. Background technology:

[0002] Massagers generally simulate the touch of human hands by swinging, moving, and vibrating to massage human muscles and nerve endings to make people feel pleasant. The swinging action of traditional massagers is usually achieved by connecting rod mechanisms and cam mechanisms, such as: a fascia gun transmission assembly with Chinese patent application number 202121828630.X. In the technical solution disclosed in this patent, a power component 4 is used to drive the massage head 2 to reciprocate through the transmission assembly 5. Since the power component 4 is a motor 35, in order to make the massage head 2 reciprocate, the transmission assembly 5 has many parts and a complex structure, and can only achieve reciprocating movement, and cannot achieve effective massage.

[0003] In addition, the massage mechanism in the current massager can usually only achieve a single action. For example, vibration cannot be achieved simultaneously in the swing mechanism. Combining the two methods together will cause the driving and transmission structure of the massager to be complex and large, resulting in a large size of the massager and inconvenient use.

[0004] In view of this, the inventor proposes the following technical solution. Utility model content:

[0005] The utility model aims to overcome the deficiencies of the prior art and provide a swing mechanism of a massage device with a simple structure.

[0007] Furthermore, in the above technical solution, the support member is in the shape of a sleeve, an inner sleeve seat for supporting and installing the telescopic mechanism is arranged inside the support member, and an avoidance groove for the swinging space of the swing arm is arranged at the upper end of the support member.

[0025] The utility model is further described below in conjunction with specific embodiments and drawings.

[0026] The utility model is a swing mechanism of a massage device. Figures 1 to 4 As shown, this is the first embodiment of the utility model, which includes: a support member 1, a swing arm 2, a telescopic mechanism 3, a linkage member 4 and a vibration motor 5.

[0027] The support member 1 is used as the mounting base of the entire swing mechanism. For ease of installation, the support member 1 can be a sleeve-shaped structure. The telescopic mechanism 3 is mounted on the inner sleeve seat 11 inside the support member 1 to achieve the positioning of the telescopic mechanism 3. The upper end opening of the support member 1 is provided with an avoidance slot 12 for the swing space of the swing arm 2.

[0028] The telescopic mechanism 3 has an output end 31 that can reciprocate and retract. The telescopic mechanism 3 can directly use a telescopic motor, and the output shaft of the telescopic motor is the output end 31. Of course, a linear reciprocating mechanism driven by a motor, such as a cam mechanism, a connecting rod mechanism, etc., can also be used.

[0029] The swing arm 2 includes: a body 20 and a hinged arm 21 in a "V" shape with the body 20. The angle between the body 20 and the hinged arm 21 can be set according to the actual installation space of the product and the position that needs to be massaged. The hinged arm 21 is hinged to the support member 1 through the first pin 6, and the position of the hinged arm 21 away from the first pin 6 is linked to the linking member 4 through the second pin 7. The telescopic mechanism 3 drives the linking member 4 to reciprocate up and down, and the linking member 4 drives the swing arm 3 to swing back and forth with the first pin 6 as the hinge fulcrum while reciprocating.

[0030] Specifically, in the first embodiment, the linkage 4 includes a collar portion 41 for sleeved on the telescopic mechanism 3 and an articulated seat 42 provided on the collar portion 41 and for being hinged to the swing arm 2. The output end 31 of the telescopic mechanism 3 is provided with a sleeve portion 32, and the sleeve 32 has a flange 320 adapted to the collar portion 41. Two articulated seats 42 are arranged in parallel on the linkage 4, and the second pin shaft 7 passes through the articulated arm 21 and the two articulated seats 42.

[0031] The swing arm 2 is fixed in the avoidance slot 12 through the first pin 6, so as to realize the hinge connection between the articulated arm 21 and the support member 1. The end of the articulated arm 21 extends into the support member 1 and is connected to the linkage member 4, and the body 20 of the swing arm 2 is exposed outside the support member 1, so that the body 20 serves as a massage component.

[0032] Since the output end 31 of the telescopic mechanism 3 is in a linear reciprocating motion up and down, in order to realize that the linking member 4 drives the swing arm 2 to swing while reciprocating, the second pin 7 on the articulated arm 21 will produce a lateral displacement during the swinging process of the swing arm 2, and the greater the swing amplitude of the swing arm 2, the greater the lateral displacement. Therefore, in order to realize that the swing arm 2 can swing normally, the sleeve part 41 and the sleeve part 32 are connected with a movable connection with a lateral movable margin. The solution adopted in the first embodiment is: the collar part 41 is semicircular, and there is a certain gap between the flange 320 of the sleeve 32 and the collar part 41, so that the sleeve part 41 and the sleeve part 32 are not fixedly connected, and the linking member 4 can achieve a certain lateral displacement while reciprocating up and down. At the same time, during the lateral displacement, the flange 320 and the collar part 41 are limited to keep the sleeve part 41 and the sleeve part 32 from completely disengaging.

[0033] The vibration motor 5 of the utility model is installed inside the body 20 of the swing arm 2, and the entire swing arm 2 is vibrated by the vibration motor 5. The vibration motor 5 is usually implemented by arranging an eccentric counterweight on the motor output shaft.

[0034] A cavity is provided in the body 20 of the swing arm 2, and the vibration motor 5 and the battery pack are provided in the cavity. The body 20 includes: a follower 22 integrally formed with or fixedly connected to the hinged arm 21, and a fixed cover 23 connected to the follower 22. The fixed cover 23 is connected to the follower 22 by a buckle, a thread or the like, and the user can replace or charge the battery through the fixed cover 23.

[0035] Combination Figure 4As shown, when the first embodiment of the present invention is working, the telescopic mechanism 3 generates an up and down telescopic reciprocating motion to drive the swing arm 2 to achieve rapid swinging, thereby generating a slapping and tapping massage action. At the same time, the vibration motor 5 generates a high-frequency vibration in the swing arm 2, thereby generating a high-frequency vibration while the swing arm 2 swings rapidly, thereby greatly improving the massage effect.

[0036] Combination Figures 5 to 7 As shown, this is the second embodiment of the utility model. Different from the first embodiment, the second embodiment overcomes the lateral displacement during the swinging process by opening a sliding hole 210 on the articulated arm 21. Specifically, the linkage member 4 in the second embodiment includes a fixed seat 43 for fixedly connecting to the output end 31 of the telescopic mechanism 3 and a linkage seat 44 arranged on the fixed seat 43 for linkage with the swing arm 2. The articulated arm 21 is provided with a sliding hole 210, and the second pin 7 is arranged on the linkage seat 44 and passes through the sliding hole 210.

[0037] After the above structure is adopted in the second embodiment, there is no need to allow a lateral movable margin between the linkage member 4 and the output end 31. In the second embodiment, the linkage member 4 is directly fixedly connected to the output end 31, and a movable space for the second pin shaft 7 is formed through the sliding hole 210 on the hinge arm 21. Of course, the second pin shaft 7 can also be set on the hinge arm 21, and a lateral displacement movable space is provided by opening a sliding hole on the linkage seat 44.

[0038] In addition, two swing arms 2 can be provided at the same time in the second embodiment. The two swing arms 2 are hinged to the support member 1 through the same first pin 6. The first pin 6 is provided at the middle position of the upper end of the support member 1, and two avoidance slots 12 are provided at the upper end opening of the support member 1, and the two swing arms 2 swing in the swing space formed by the two avoidance slots 12.

[0039] The articulated arms 21 of the two swing arms 2 are arranged opposite to each other, and two linkage seats 44 are arranged on the fixed seat 43. The articulated arms 21 of the two swing arms 2 are movably connected with the second pin shafts 7 respectively arranged on the two linkage seats 44 through their respective sliding holes 210.

[0040] Compared with the first embodiment, the second embodiment adopts another method to realize that the telescopic mechanism 3 drives the linking member 4 to reciprocate up and down, and the linking member 4 drives the swing arm 3 to swing back and forth with the first pin 6 as the hinge point while reciprocating. In addition, the use of two swing arms 2 can realize massage actions in different directions.

[0041] The main problems solved by the utility model are the complex structure of the driving device of the traditional massager and the realization of the dual massage mode of swinging and vibrating. Through the utility model, the massager can generate high-frequency vibration while swinging and massaging, so as to realize the dual-effect massage mode, which can be suitable for most massager products on the market.

[0042] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
