Description

Technical Field

[0001] This utility model relates to massage equipment technology, specifically to a massage mechanism and massage machine that are easy to assemble. Background Technology

[0002] Patent application CN201910251354.6 discloses a massage mechanism in which a lifting drive assembly drives a movable component to move up and down. During this movement, the massage mechanism swings back and forth via a transmission device to adjust the pressure. The overall structure controlling the back-and-forth swing of the massage mechanism in the aforementioned patent application is relatively complex and inconvenient to install. This application aims to provide a massage mechanism that achieves the back-and-forth movement of the massage mechanism in a way different from the aforementioned patent application. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a massage mechanism that uses a different approach from the prior art to achieve the back-and-forth movement of the massage mechanism.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a massage mechanism that is easy to assemble, comprising: a main frame; an auxiliary frame, which is connected to the main frame via a linkage mechanism and moves in the front-back direction in a controlled manner by swinging through the linkage mechanism; a massage mechanism, mounted on the auxiliary frame; and a linkage drive mechanism, mounted on the main frame to drive the linkage mechanism to swing.

[0005] Preferably, the linkage mechanism includes two sets of linkages: a first linkage, a second linkage, and a third linkage, spaced apart horizontally. The linkage drive mechanism includes a rocker arm drive motor, a lead screw, and a lifting assembly. The lead screw is vertically mounted and connected to the rocker arm drive motor. The lifting assembly slides vertically with the main frame and has a nut fitted onto the lead screw. Both sides of the first and second linkages are pivotally connected to the auxiliary frame and the lifting assembly, respectively, so that the first linkage, the second linkage, the auxiliary frame, and the lifting assembly are engaged in a parallelogram orientation. The first side of the third linkage is pivotally connected to the main frame, and the second side is pivotally connected to either the first or the second linkage.

[0006] Preferably, a walking drive mechanism is installed on the main frame, the walking drive mechanism including an upper walking shaft installed on the main frame and extending left and right; the first side of the third link is indirectly pivotally connected to the main frame by pivotally connecting to the upper walking shaft.

[0007] Preferably, the auxiliary frame has a clearance groove corresponding to the second side position of the third link, and the second side of the third link is engaged in the clearance groove when it is in the backward swing position.

[0008] Preferably, the lifting assembly includes the nut, the nut seat, and the slider. The nut is sleeved on the lead screw. The nut seat has a mounting groove for mounting the nut. The nut is installed in the mounting groove and is integrally sleeved on the lead screw with the nut seat. The nut seat is installed on the slider. The slider slides in a vertical engagement with the main frame.

[0009] Preferably, the main frame has sliding grooves on the left and right sides, the sliding grooves facing inward in the left and right direction and extending up and down, and the left and right sides of the slider are embedded in the sliding grooves.

[0010] Preferably, the auxiliary frame is equipped with a tapping drive mechanism for driving the massage mechanism to swing back and forth around the rotation center to perform tapping massage.

[0011] Preferably, the rotation center is a left-right extending shaft.

[0012] This application also provides a massage machine comprising the massage mechanism described in any of the preceding claims.

[0013] Preferably, the massage machine is a massage chair.

[0014] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. In the massage mechanism of this application, the auxiliary frame is connected to the main frame through a linkage mechanism, and the massage mechanism is installed on the auxiliary frame. This structural layout is clearly layered, which allows the components installed on the main frame and the auxiliary frame to be installed independently first and then assembled, which helps to improve production efficiency. 2. The auxiliary frame has a clearance groove corresponding to the second side position of the third link. When the third link is in the backward swing position, its second side is engaged in the clearance groove. The existence of the clearance groove makes the linkage mechanism occupy less space in the front-back direction when it is in the longitudinal folding state, and the overall structure is more compact.

Detailed Implementation

[0018] 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.

[0019] 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.

[0020] Combination Figures 1 to 12In one embodiment, the massage mechanism of this application, which is easy to assemble, includes a main frame 1, a walking drive mechanism 2, an auxiliary frame 3, a linkage drive mechanism 4, a linkage mechanism 5, a massage mechanism 6, a body pressure detection mechanism 7, and a tapping drive mechanism 8. The control mechanism and other structures of the massage mechanism are omitted in the figures. The control mechanism is electrically connected to the walking drive mechanism 2, the linkage drive mechanism 4, the body pressure detection mechanism 7, and the tapping drive mechanism 8 of the massage mechanism to control the operation of these components or to receive the operating status information of these components, and will not be described in detail here. The following will describe the details in conjunction with the figures. For ease of explanation, the X direction in the figures represents the direction of the massage mechanism from right to left, the Y direction represents the direction from back to front, and the Z direction represents the direction from bottom to top.

[0021] [Main Frame] Combination Figure 3 The main frame 1 is generally a cuboid frame structure, comprising frame members joined sequentially. The main frame 1 has sliding grooves 1A on both the left and right sides, extending inwards in the left-right direction and vertically. The sliding grooves 1A are used for sliding engagement with the lifting assembly 4C of the linkage drive mechanism 4. The travel drive mechanism 2 and the linkage drive mechanism 4 are mounted on the main frame 1.

[0022] [Walking Drive Mechanism] The walking drive mechanism 2 is installed on the main frame 1. When the massage mechanism is mounted on the frame of a massage machine (e.g., the frame of a massage chair), the walking drive mechanism 2 drives the entire massage mechanism to move along the frame, allowing for massage of different positions on the user's limbs (e.g., the back). The walking drive mechanism 2 includes a walking drive motor 2A, an upper walking shaft 2B, and a lower walking shaft 2C. The walking drive motor 2A and the upper walking shaft 2B are installed on the upper side of the main frame 1. The upper walking shaft 2B extends left and right, and the walking drive motor 2A is connected to the upper walking shaft 2B to drive its rotation. Upper walking wheels are provided on the left and right sides of the upper walking shaft 2B, and walking gears (not shown) may also be provided on its left and right sides. The lower walking shaft 2C is installed on the lower side of the main frame 1. In this embodiment, the lower walking shaft 2C is a short shaft, located on the left and right sides of the main frame 1, with lower walking wheels provided on its outer side. In another embodiment, the downward straight shaft 2C can be adjusted into a long shaft structure, similar to the upper traveling shaft 2B. In this embodiment, the upper traveling shaft 2B is driven to rotate by the traveling drive motor 2A, that is, the upper traveling shaft 2B is the active shaft. In another embodiment, the active shaft and the traveling drive motor 2A can be adjusted to be installed on the lower side of the main frame 1, that is, the positions of the upper traveling shaft 2B and the lower traveling shaft 2C are swapped.

[0023] [Auxiliary Frame] Auxiliary frame 3 is located on the front side of main frame 1, combined with Figure 9The auxiliary frame 3 moves in a controlled manner relative to the main frame 1 in the front-back direction. In this embodiment, the auxiliary frame 3 is connected to the main frame 1 via a linkage mechanism 5, and moves in the front-back direction in a controlled manner by swinging the linkage mechanism 5. The linkage drive mechanism 4 is used to drive the linkage mechanism 5 to swing. The massage mechanism 6, the rotation center L, the body pressure detection mechanism 7, and the tapping drive mechanism 8 are all mounted on the auxiliary frame 3. Figure 3 In this embodiment, the auxiliary frame 3 includes longitudinal side beams 3A located on the left and right sides, a bottom beam 3B connecting the lower sides of the two longitudinal side beams 3A, and a middle beam 3C connecting the middle of the two longitudinal side beams 3A. A mounting part 3D is provided in the middle of the rear side of the bottom beam 3B, and a mounting groove 3E is provided in the middle of the middle beam 3C. A rotation center L is installed in the mounting groove 3E. When the massage mechanism 6 is driven by the tapping drive mechanism 8, it swings back and forth around the rotation center L to perform tapping massage on the user's limbs. In this embodiment, the rotation center L is a left-right extending shaft. The massage mechanism 6 is pivotally connected to the rotation center L via a body pressure detection mechanism 7. The rotation center L can be installed on the auxiliary frame 3 by fastening screws or a snap-fit ​​structure. It should be understood that the specific structure of the rotation center L is not limited to this; for example, it can be adjusted to a U-shaped ear to pivotally engage with the body pressure detection mechanism 7. The rotation center L can be designed to be integrally formed on the auxiliary frame 3. The specific way in which the body pressure detection mechanism 7 is pivotally connected to the rotation center L is not limited to being directly pivotally connected to the rotation center L, but can also be adjusted to be indirectly pivotally connected to the rotation center L through a pivoting structure.

[0024] [Linkage Drive Mechanism] The linkage drive mechanism 4 is mounted on the main frame 1, and it is used to drive the linkage mechanism 5 to swing, combined with... Figure 9 The linkage drive mechanism 4 can drive the linkage mechanism 5 to switch between a longitudinally folded state and a laterally extended state, thereby correspondingly driving the auxiliary frame 3 to switch between a rear position and a front position.

[0025] Combination Figure 3In this embodiment, the linkage drive mechanism 4 includes a swing arm drive motor 4A, a lead screw 4B, and a lifting assembly 4C. The swing arm drive motor 4A is installed in the middle of the lower side of the main frame 1. The lead screw 4B is arranged vertically and is connected to the swing arm drive motor 4A. The left and right sides of the lifting assembly 4C are embedded in the sliding groove 1A, thereby slidingly engaging with the main frame 1 in the vertical direction. The lifting assembly 4C includes a nut M1, a nut seat M2, and a slider M3. The nut M1 is sleeved on the lead screw 4B. The nut seat M2 has a mounting groove for mounting the nut M1. The nut M1 is installed in the mounting groove and is integrally sleeved on the lead screw 4B with the nut seat M2. The nut seat M2 is installed on the slider M3 (which can be connected by fastening screws). The left and right sides of the slider M3 are embedded in the sliding groove 1A, thereby slidingly engaging with the main frame 1 in the vertical direction. When the lead screw 4B is driven to rotate by the swing arm drive motor 4A, the nut M1 of the lifting assembly 4C moves vertically relative to the lead screw 4B. By adjusting the rotation direction of the lead screw 4B, the lifting assembly 4C can be controlled to move upward or downward. In another embodiment, the swing arm drive motor 4A can be adjusted to be installed at the middle of the upper side of the main frame 1. The way the lifting assembly 4C slides with the main frame 1 in the vertical direction is not limited to the slide groove 1A; a roller structure can be provided between them, which allows the lifting assembly 4C to slide relatively smoothly up and down relative to the main frame 1.

[0026] [Linkage Mechanism] Linkage mechanism 5 is located between the main frame 1 and the auxiliary frame 3. As mentioned earlier, linkage mechanism 5 can switch between a longitudinally folded state and a laterally extended state. Combined with... Figures 4 to 9 In this embodiment, the linkage mechanism 5 includes a first linkage 5A, a second linkage 5B, and a third linkage 5C, which are two sets arranged at intervals on the left and right.

[0027] Both the first link 5A and the second link 5B are pivotally connected to the auxiliary frame 3 and the lifting assembly 4C on both sides, so that the first link 5A, the second link 5B, the auxiliary frame 3, and the lifting assembly 4C are joined in a parallelogram orientation.

[0028] In this embodiment, the first side of the third link 5C is pivotally connected to the main frame 1. In this embodiment, the first side of the third link 5C is indirectly pivotally connected to the main frame 1 by pivoting to the upper traveling shaft 2B. However, it should be understood that the third link 5C can also be adjusted to be directly pivotally connected to the main frame 1. The second side of the third link 5C is pivotally connected to the second link 5B. In another embodiment, the second side of the third link 5C can also be adjusted to be pivotally connected to the first link 5A. In this embodiment, the auxiliary frame 3 has a clearance groove G corresponding to the position of the second side of the third link 5C. When the third link 5C is in the rearward swing position, its second side is engaged in the clearance groove G. Figure 9The presence of the clearance groove G makes the linkage mechanism 5 occupy less space in the front-to-back direction when it is in the longitudinal folded state, resulting in a more compact overall structure.

[0029] [Massage Mechanism] Massage mechanism 6 is used to massage the user's limbs. This embodiment, in conjunction with... Figure 3 and Figure 4 In this embodiment, the massage mechanism 6 includes a detection mechanism joint 6A, a massage arm 6B, and a tapping mechanism joint 6C. In this embodiment, the three are integrated into one structure.

[0030] The detection mechanism joint 6A is located behind the rotation center L, and a body pressure detection mechanism 7 is disposed between it and the rotation center L. The detection mechanism joint 6A is connected to the rear side of the pressure detection mechanism 7 via a connector P.

[0031] The massage arms 6B are located on the left and right sides of the intermediate joint 6A, and massage components are mounted on them. In this embodiment, the massage components are massage rollers. In this embodiment, the massage arms 6B are roughly U-shaped, with their rear sides joined to the detection mechanism joint 6A, and massage components are provided on their upper and lower sides. Figure 7 In the vertical direction, the central beam 3C is located between the upper and lower sides of the massage arm 6B, making the overall structure of the massage mechanism more compact. In another embodiment, the massage arm 6B can be adjusted to exclude the lower part.

[0032] In this embodiment, the tapping mechanism joint 6C is located below the detection mechanism joint 6A and engages with the tapping drive mechanism 8. The tapping mechanism joint 6C is a pivot lug that bends forward relative to the detection mechanism joint 6A and extends forward and backward. The two tapping mechanism joints 6C are spaced apart to form a space between them for accommodating the tapping connector 8C, which houses the tapping drive mechanism 8. The forward bending of the tapping mechanism joint 6C relative to the detection mechanism joint 6A reduces the space occupied by the massage mechanism in the forward and backward direction, resulting in a more compact overall structure.

[0033] Prior art, such as patent application CN201910251354.6, typically includes a pair of massage mechanisms spaced apart from each other. However, the massage mechanism 6 of this embodiment includes massage arms 6B located on the left and right sides of the intermediate joint 6A. This embodiment is equivalent to joining a pair of massage mechanisms into one unit. The advantage of this structure is that the tapping drive mechanism 8 only needs to include one tapping connector 8C to drive the massage arms 6B on both sides to swing back and forth synchronously (prior art, such as patent application CN201910251354.6, requires two tapping connectors). In addition, the structure of the massage mechanism 6 in this embodiment can be connected to the body pressure detection mechanism 7 through the intermediate joint 6A to perform body pressure detection.

[0034] [Body Pressure Detection Mechanism] The body pressure detection mechanism 7 is used to detect the body pressure information received by the massage mechanism 6. The body pressure detection mechanism 7 is disposed between the massage mechanism 6 and the rotation center L. In this embodiment, one side of the body pressure detection mechanism 7 is connected to the detection mechanism joint 6A of the massage mechanism 6 via a connector P, and the other side of the body pressure detection mechanism 7 is pivotally connected to the rotation center L. Through this connection method, when the massage mechanism 6 is driven by the tapping drive mechanism 8, it will swing back and forth around the rotation center L as a whole, along with the body pressure detection mechanism 7. Figure 11 In this embodiment, the body pressure detection mechanism 7 includes a first housing 7A, a second housing 7B, and a body pressure sensor 7C. The first housing 7A is pivotally connected to the rotation center L, the second housing 7B is connected to the massage mechanism 6 through a connector P, and the body pressure sensor 7C is installed between the first housing 7A and the second housing 7B. The body pressure sensor 7C can be a common tension sensor, which will not be described in detail here.

[0035] [Tapping Drive Mechanism] The tapping drive mechanism 8 drives the massage mechanism 6 to oscillate back and forth around the rotation center L. Combined with... Figure 3 In this embodiment, the striking drive mechanism 8 includes a striking drive motor 8A, a striking shaft 8B, and a striking connector 8C. The striking drive motor 8A and the striking shaft 8B are mounted on the mounting portion 3D of the auxiliary frame 3, and combined with... Figure 4 , Figure 8 , Figure 12 The striking shaft 8B has an eccentric portion 8B1. A first side of the striking connector 8C is rotatably fitted onto the eccentric portion 8B1, and a second side of the striking connector 8C is pivotally connected to the striking mechanism engagement portion 6C. The pivotal connection between the second side of the striking connector 8C and the striking mechanism engagement portion 6C is not limited to relative rotation around a set axis; a ball joint pivotal connection can also be used. In this embodiment, a counting wheel T is mounted on the striking shaft 8B and rotates accordingly. The counting wheel T can cooperate with a photoelectric switch (not shown) mounted on the auxiliary frame 3 to detect the rotational speed and position of the striking shaft 8B.

[0036] The above is a detailed description of a massage mechanism according to an embodiment of this application. In this embodiment, the body pressure detection mechanism 7 is disposed between the massage mechanism 6 and the rotation center L. When the massage mechanism 6 is driven by the tapping drive mechanism 8, it and the body pressure detection mechanism 7 swing back and forth around the rotation center L. The body pressure detection mechanism 7 not only detects the body pressure on the massage mechanism 6, but also connects the massage mechanism 6 to the rotation center L. The overall structure is compact. The massage mechanism of this application includes a main frame 1 and an auxiliary frame 3. The walking drive mechanism 2 and the linkage drive mechanism 4 are installed on the main frame 1, while the massage mechanism 6, the rotation center L, the body pressure detection mechanism 7, and the tapping drive mechanism 7 are installed on the auxiliary frame 3. The auxiliary frame 3 is connected to the main frame 1 by the linkage mechanism 5. This structural layout is hierarchical, allowing the components installed on the main frame 1 and the auxiliary frame 3 to be installed independently first, and then assembled, which helps to improve production efficiency.

[0037] [Variant Embodiments] It should be understood that the embodiments of this application are not limited thereto. Specifically, the linkage drive mechanism 4 is not limited to the use of a lead screw and nut mating structure. For example, the linkage drive mechanism 4 can be adjusted to include a telescopic push rod, which controls the up and down movement of the slider M3.

[0038] [Massage Machine] This application also provides a massage machine comprising the massage mechanism described in any of the foregoing claims. The massage machine may be, for example, a massage chair or a massage cushion.

[0039] 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.
