Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0030] Combination Figures 1 to 10In one embodiment, the massage mechanism of this application includes a frame 1, a massage mechanism 2, and a drive device for driving the massage mechanism 2. In this embodiment, the drive device includes a motor 3, a first shaft 4, a transmission assembly 5, an eccentric hub 6, a limiting rod 7, and a force adjustment mechanism 8. The motor 3 drives the first shaft 4 to rotate via the transmission assembly 5. When the first shaft 4 rotates, it drives the massage mechanism 2 to oscillate left and right via the eccentric hub 6. The force adjustment mechanism 8, via the limiting rod 7, drives the massage mechanism 2 to oscillate relative to the eccentric hub 6 in the front-back direction, thereby adjusting the massage force when the massage mechanism 2 oscillates back and forth. The following will describe this in further detail with reference to the figures. For ease of explanation, the X direction in the figures is from right to left, the Y direction is from back to front, and the Z direction is from bottom to top.

[0031] The frame 1 comprises a main body 1A and a cover 1B. The outer periphery of the main body 1A is approximately rectangular plate-shaped. The front of the main body 1A has a mounting slot for the motor 3 and transmission assembly 5, as well as a bearing for supporting the first shaft support 4. A through hole S is provided on the main body 1A for connecting the air guide assembly (not shown) to the nozzle end N of the force adjustment mechanism 8. The cover 1B is mounted on the front of the main body 1A and covers the motor 3 and transmission assembly 5. The air guide assembly includes components such as a pneumatic magnet, a valve, and an air pipe, which will not be described in detail here.

[0032] Massage mechanism 2 includes massage arm 2A and separate component 2B, combined Figure 4 and Figure 5 The separating component 2B is screwed onto the massage arm 2A, and the two cooperate to form a first ball joint P1, which is used to engage one end of the limiting rod 7. In this embodiment, the massage arm 2A of the massage mechanism 2 is only provided with a massage part on its upper side, but it should be understood that in another embodiment, a massage part may also be provided on the lower side of the massage arm 2A. The massage part can be adjusted to a common massage roller, and the massage part may be provided with a heating element for heat therapy massage. The massage mechanism 2 and the intensity adjustment mechanism 8 are two sets, arranged alternately on the left and right sides.

[0033] The motor 3 is used to drive the first shaft 4 to rotate, and it is installed between the two massage mechanisms 2. The motor 3 is configured in the mounting groove on the front side of the main body 1A.

[0034] The first shaft support 4 extends to the left and right, and its left and right sides are supported on the front side of the main body 1A by bearings.

[0035] The transmission assembly 5 is located between the motor 3 and the first shaft support 4. It includes a transmission rod 5A, a first worm gear structure (including a first worm 5B and a first worm wheel 5C), and a second worm gear structure (including a second worm 5D and a second worm wheel 5E). The transmission rod 5A is arranged vertically. The upper side of the transmission rod 5A is supported on the main body 1A of the frame 1 by an upper bearing 5F, and the lower side of the transmission rod 5A is supported on the main body 1A of the frame 1 by a lower bearing 5G. A first shock absorber 9A is provided on the upper side of the upper bearing 5F, and a second shock absorber 9B is provided on the lower side of the lower bearing 5G. The first shock absorber 9A is located between the upper bearing 5F and the main body 1A, and the second shock absorber 9B is located between the lower bearing 5G and the main body 1A. When the massage mechanism 2 swings back and forth, the body pressure transmitted to the transmission rod 5A through the first shaft support 4 can be absorbed by the first shock absorber 9A and the second shock absorber 9B, thereby reducing the impact of the body pressure on the motor 3 and extending the service life of the motor 3. In this embodiment, both the first damping element 9A and the second damping element 9B are wave washers, but it can also be adjusted so that only one is a wave washer. The first worm 5B is mounted on the output shaft of the motor 3 and is driven to rotate by the motor 3. The first worm wheel 5C is sleeved on the transmission rod 5A and meshes with the first worm 5B. The second worm 5D is sleeved on the transmission rod 5A, and the second worm wheel 5E is sleeved on the first shaft support 4 and meshes with the second worm 5D.

[0036] An eccentric hub 6 is mounted on the first shaft support 4 and rotates with the first shaft support 4. A massage mechanism 2 is supported on the eccentric hub 6. Figure 4 The massage mechanism 2 has a socket T, and the eccentric hub 6 has an eccentric wheel 6A and a fixing part 6B. The socket T of the massage mechanism 2 is fitted onto the eccentric wheel 6A, and the fixing part 6B is fixed to the eccentric wheel 6A by screws. The two cooperate to clamp the massage mechanism 2. Through the above-mentioned engagement method, the massage mechanism 2 and the eccentric hub 6 rotate and are driven by the rotation of the eccentric hub 6 to swing left and right.

[0037] The limiting rod 7 is installed between the force adjustment mechanism 8 and the massage mechanism 2. Both ends of the limiting rod 7 are spherical structures, with its first end positioned within the first ball joint P1, thus spherically hinged to the massage mechanism 2. The limiting rod 7 allows the massage mechanism 2 to oscillate left and right while restricting its rotation with the eccentric hub 6.

[0038] The intensity adjustment mechanism 8, via the limit rod 7, drives the massage mechanism 2 to swing relative to the eccentric hub 6 in the front-to-back direction, thereby changing the massage intensity of its swinging motion by altering the forward tilt position of the massage mechanism 2 (in combination with...). Figure 10 Specifically, in this embodiment, the force adjustment mechanism 8 includes a swing member 8A and an airbag member 8B. Combined with... Figure 9The swing member 8A includes a pivot lug M1, an airbag mating part M2, and a separating part M3. The pivot lug M1 is pivotally connected to the main body 1A of the frame 1 via a second shaft Q, thereby enabling the swing member 8A to swing back and forth relative to the frame 1. In this embodiment, the swing axis L2 of the swing member 8A is parallel to the rotation axis L1 of the first shaft 4. The airbag mating part M2 is used to engage the airbag member 8B. The separating part M3 is installed on the airbag mating part M2 by screws, and the two cooperate to form a second ball joint P2. The second end of the limiting rod 7 is disposed in the second ball joint P2. The airbag member 8B is installed between the main body 1A of the frame 1 and the airbag mating part M2 of the swing member 8A, so as to drive the swing member 8A to swing by inflation or deflation. The air nozzle end N of the air belt member 8B passes through the aforementioned through hole S. In this embodiment, a reset member G is provided between the swing member 8A and the main body 1A of the frame 1 to apply a reset force to the swing member 8A. In this embodiment, the reset member G is a torsion spring, which includes a helical part G1 sleeved on the second shaft support Q, a first torsion arm G2 abutting against the main body 1A of the frame 1, and a second torsion arm G3 abutting against the swing member 8A.

[0039] The above describes the specific structure of the massage mechanism according to one embodiment of this application. It should be understood that the implementation of this application is not limited to this. In another embodiment, the massage mechanism 2 and the intensity adjustment mechanism 8 can be adjusted to form one group, three groups, or more. In another embodiment, the configuration position of the motor 3 can be adjusted, such as adjusting it to be installed on the rear side of the main body 1A.

[0040] This application also provides a car seat that includes the massage mechanism described in any of the preceding claims.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
