Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a reciprocating opening and closing pinching massage mechanism. Background Technology

[0002] Currently, massage devices generally use mechanical methods to massage and relax the human body. When muscles feel sore and tense due to fatigue, using massage devices can relax muscles and improve blood circulation, relax muscles that are tense after exercise, and effectively reduce fatigue and soreness caused by exercise and mental stress. Massage devices are generally designed based on human hand massage techniques, thereby achieving or even surpassing the effects of human hand massage. Common massage techniques include pressing, pinching, rubbing, kneading, pushing, grasping, stroking, patting, shaking, and vibrating.

[0003] However, the massage mechanisms used in existing small handheld massagers generally massage the body muscles through motor vibration or left-right swinging motions. Their massage methods are relatively simple and conventional. Currently, no small handheld massager has a massage mechanism that can perform pinching massage. While large massage devices can perform pinching massage, they have complex structures, complicated assembly processes, high production costs, and large size, taking up a lot of space and making them inconvenient to store. Utility Model Content

[0004] The purpose of this utility model is to provide a reciprocating opening and closing pinching massage mechanism, which aims to solve the technical problems of complex structure and inconvenient assembly of existing pinching massage mechanisms.

[0005] To achieve the above objectives, the present invention provides a reciprocating opening and closing pinching massage mechanism, comprising a housing and a massage driving mechanism, wherein the massage driving mechanism includes:

[0006] A first clamping arm, which is pivotally connected to one side of the housing;

[0007] A second clamping arm, pivotally connected to the other side of the housing, wherein the first end of the first clamping arm and the first end of the second clamping arm are spaced apart from each other; and

[0008] A driving component is disposed on the housing and is drivenly connected to the second end of the first clamping arm and the second end of the second clamping arm, respectively, so as to drive the first end of the first clamping arm and the first end of the second clamping arm to reciprocate opening and closing swing in a manner that moves closer to or further away from each other, thereby generating a pinching massage action.

[0009] Furthermore, the driving component includes:

[0010] A rotating wheel assembly, wherein the rotation axis of the rotating wheel assembly is configured to be perpendicular to the swing axis of the first clamping arm, the swing axis of the first clamping arm and the swing axis of the second clamping arm are parallel and not collinear, and the rotating wheel assembly has a first cam connection and a second cam connection.

[0011] The drive unit is used to drive the rotating wheel assembly to rotate;

[0012] A first conversion unit, through its engagement with the first cam connection, converts the rotational motion of the rotating wheel assembly into a reciprocating oscillating motion of the first clamping arm around its swing axis; and

[0013] The second conversion unit, through its cooperation with the second cam connection, converts the rotational motion of the rotating wheel assembly into the reciprocating oscillating motion of the second clamping arm around its swing axis, and causes the second clamping arm and the first clamping arm to reciprocate oscillating in a manner that moves closer to or further away from each other.

[0014] Furthermore, the first cam connection has:

[0015] The first boss wheel is eccentrically positioned relative to the rotation axis of the rotating wheel assembly, and a first cam surface is formed on the outer circumferential surface of the first boss wheel;

[0016] The second cam connection has:

[0018] The first conversion unit includes:

[0019] A first sliding portion, the first sliding portion having a first annular hole, and the first sliding portion being movably engaged with the first cam surface of the first boss wheel through the first annular hole; and

[0020] A first conversion connection is connected between the first sliding part and the second end of the first clamping arm, so as to convert the movement of the first sliding part into the reciprocating swinging motion of the first clamping arm around its swing axis through the first conversion connection.

[0021] The second conversion unit includes:

[0022] The second sliding part has a second annular hole, and the second sliding part is movably engaged with the second cam surface of the second boss wheel through the second annular hole;

[0023] A second conversion connection is connected between the second sliding part and the second end of the second clamping arm, so as to convert the movement of the second sliding part into the reciprocating swinging motion of the second clamping arm around its swing axis; and

[0024] The guide structure guides the first sliding part and the second sliding part to move along a motion path perpendicular to the swing axis while the rotating wheel set is rotating. At the same time, the first sliding part and the second sliding part move in opposite directions, so that the first end of the first clamping arm and the first end of the second clamping arm reciprocate in a manner that moves closer to each other or further away from each other.

[0025] Furthermore, the first conversion connection includes:

[0026] A first shaft is disposed on the left side of the first sliding portion, and the central axis of the first shaft extends along a swing axis parallel to the first clamping arm; and

[0027] The first swing arm slot is disposed at the second end of the first clamping arm and is movably engaged on the first shaft.

[0029] A second shaft is disposed on the right side of the second sliding portion, and the central axis of the second shaft extends along a swing axis parallel to the second clamping arm; and

[0030] The second swing arm slot is disposed at the second end of the second clamping arm and is movably engaged on the second shaft.

[0031] Furthermore, the guiding structure includes:

[0032] A fixed base, wherein the fixed base extends along the swing axis perpendicular to the first clamping arm and has a guide groove;

[0033] A first slider is disposed at the end of the first sliding portion and is slidably mounted within the guide groove, so that the first sliding portion is guided to move along a movement path perpendicular to the swing axis of the first clamping arm by sliding the first slider along the extending direction of the guide groove; and

[0034] The second slider is disposed at the end of the second sliding part and is slidably mounted in the guide groove so that the second sliding part can be guided to move along a movement path perpendicular to the swing axis of the second clamping arm by sliding the second slider along the extension direction of the guide groove.

[0035] Furthermore, the second end of the first clamping arm bends and extends from the rear side of the housing to the left side of the housing and is fixedly connected to the first swing arm slot, and the second end of the second clamping arm bends and extends from the front side of the housing to the right side of the housing and is fixedly connected to the second swing arm slot.

[0036] As can be seen from the above technical solution, the reciprocating opening and closing pinching massage mechanism of this utility model pivotally connects the first clamping arm and the second clamping arm to the two sides of the housing, respectively. The first end of the first clamping arm and the first end of the second clamping arm are driven by the drive component to reciprocate and swing in a way that moves closer to each other or further away from each other, thereby generating a pinching massage action between the first end of the first clamping arm and the first end of the second clamping arm to pinch and massage the skin and muscles, thereby relaxing the muscles, relieving fatigue, and promoting blood circulation. Moreover, the structural design is simple and compact, the drive method is stable and reliable, and it further enriches the massage mode of the massager.

[0047] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] Please refer to the following: Figures 1 to 5 This embodiment provides a reciprocating opening and closing pinching massage mechanism, including a housing and a massage driving mechanism, the massage driving mechanism including:

[0049] The first clamping arm 410 is pivotally connected to one side of the housing;

[0050] The second clamping arm 420 is pivotally connected to the other side of the housing, and the first end of the first clamping arm 410 and the first end of the second clamping arm 420 are spaced apart from each other; and

[0051] A drive assembly is disposed on the housing and is driven to the second end of the first clamping arm 410 and the second end of the second clamping arm 420 respectively, so as to drive the first end of the first clamping arm 410 and the first end of the second clamping arm 420 to reciprocate opening and closing swing in a manner that moves closer to or further away from each other, thereby generating a pinching massage action.

[0052] As can be seen, the reciprocating opening and closing pinching massage mechanism of this embodiment pivotally connects the first clamping arm 410 and the second clamping arm 420 to both sides of the housing. The first end of the first clamping arm 410 and the first end of the second clamping arm 420 are driven by the drive assembly to reciprocate and swing in a way that moves closer to or further away from each other, thereby generating a pinching massage action between the first end of the first clamping arm 410 and the first end of the second clamping arm 420 to pinch and massage the skin and muscles, thereby relaxing the muscles, relieving fatigue, and promoting blood circulation. Moreover, the structure is simple and compact, the drive method is stable and reliable, and the massage mode of the massager is further enriched.

[0053] Among them, such as Figures 4 to 5 As shown, the first end of the first clamping arm 410 and the first end of the second clamping arm 420 are both plate-shaped structures. Both sides of the first clamping arm 410 extend outward to form a first pivot 411, and both sides of the second clamping arm 420 extend outward to form a second pivot 421. The upper cover 530 of the fixing seat 510 is provided with a pair of first pivot grooves 531 and a pair of second pivot grooves 532. The first pivot grooves 531 and the second pivot grooves 532 are respectively provided on two opposite side edges of the upper cover 530 of the fixing seat 510. The first clamping arm 410 is rotatably fitted into the pair of first pivot grooves 531 through the two ends of the first pivot 411, thereby pivotally connected to the housing 100. The second clamping arm 420 is rotatably fitted into the pair of second pivot grooves 532 through the two ends of the second pivot 421, thereby pivotally connected to the housing 100.

[0054] Specifically, such as Figures 3 to 5 As shown, the drive assembly includes a rotating wheel set 470, a drive unit 480, a first conversion unit 430, and a second conversion unit 440. The rotation axis of the rotating wheel set 470 is configured to be perpendicular to the swing axis of the first clamping arm 410. The swing axis of the first clamping arm 410 is parallel to the swing axis of the second clamping arm 420. The rotating wheel set 470 has a first cam connection and a second cam connection. The drive unit 480 is used to drive the rotating wheel set 470 to rotate. The rotational motion of the rotating wheel set 470 is converted into a reciprocating swing motion of the first clamping arm 410 around its swing axis by cooperating with the first cam connection through the first conversion unit 430. The rotational motion of the rotating wheel set 470 is converted into a reciprocating swing motion of the second clamping arm 420 around its swing axis by cooperating with the second cam connection through the second conversion unit 440. The second clamping arm 420 and the first clamping arm 410 reciprocate in a manner that moves closer to each other or further away from each other.

[0055] Among them, such as Figure 4 and Figure 5As shown, the housing includes a fixed base 510, the upper cover 530 of which covers the cup holder. The bottom of the rotating wheel assembly 470 has a cross-shaped mounting groove 473. The drive unit 480 is a geared motor, and the output shaft 481 of the geared motor is cross-shaped for circumferential positioning. The output shaft 481 of the drive unit 480 is inserted into the mounting groove 473 of the rotating wheel assembly 470. The drive unit 480 is installed under the base 520 of the fixed base 510, and the rotating wheel assembly 470 is located inside the fixed base 510. The rotating wheel assembly 470 is driven to rotate by the drive unit 480, and the rotational force of the rotating wheel assembly 470 is transmitted to the first conversion unit 430 and the second conversion unit 440 through the first cam connection and the second cam connection of the rotating wheel assembly 470, respectively. This causes the first conversion unit 430 and the second conversion unit 440 to push and pull the second end of the first clamping arm 410 and the second end of the second clamping arm 420, respectively, thereby causing the first end of the first clamping arm 410 and the first end of the second clamping arm 420 to reciprocate in a manner that moves closer to or further away from each other.

[0056] Furthermore, such as Figure 3 and Figure 5 As shown, the first cam connection has a first boss wheel 471, which is eccentrically positioned relative to the rotation axis of the rotating wheel assembly 470, and a first cam surface is formed on the outer peripheral surface of the first boss wheel 471; the second cam connection has a second boss wheel 472, which is eccentrically positioned and stacked on the first boss wheel 471 relative to the rotation axis of the rotating wheel assembly 470, and a second cam surface is formed on the outer peripheral surface of the second boss wheel 472.

[0057] The first conversion part 430 includes a first sliding part 431 and a first conversion connection part 450. The first sliding part 431 has a first annular hole 432 and is movably engaged with the first cam surface of the first boss wheel 471 through the first annular hole 432. The first conversion connection part 450 is connected between the first sliding part 431 and the second end of the first clamping arm 410 so as to convert the moving motion of the first sliding part 431 into the reciprocating swing motion of the first clamping arm 410 around its swing axis through the first conversion connection part 450.

[0058] The second conversion part 440 includes a second sliding part 441, a second conversion connecting part 460, and a guide structure 500. The second sliding part 441 has a second annular hole 442 and is movably engaged with the second cam surface of the second boss wheel 472 through the second annular hole 442. The second conversion connecting part 460 connects the second sliding part 441 and the second end of the second clamping arm 420 to convert the movement of the second sliding part 441 into the reciprocating swinging movement of the second clamping arm 420 around its swing axis. When the rotating wheel set 470 is rotating, the guide structure 500 guides the first sliding part 431 and the second sliding part 441 to move along a movement path perpendicular to the swing axis, and at the same time, the movement directions of the first sliding part 431 and the second sliding part 441 are opposite, so that the first end of the first clamping arm 410 and the first end of the second clamping arm 420 reciprocate in a manner that moves closer to each other or further away from each other.

[0059] Among them, such as Figures 4 to 5 As shown, the shapes of the first annular hole 432 and the second annular hole 442 are both approximately elliptical or waist-shaped. When the drive unit 480 drives the rotating wheel assembly 470 to rotate, the first boss wheel 471 and the second boss wheel 472 of the rotating wheel assembly 470 rotate together around the rotation axis. The first cam surface of the first boss wheel 471 rolls into contact with the inner wall of the first annular hole 432 of the first sliding part 431, and the second cam surface of the second boss wheel 472 rolls into contact with the inner wall of the second annular hole 442 of the second sliding part 441, thereby transmitting the rotational force of the first boss wheel 471 and the rotational force of the second boss wheel 472 to the first sliding part 431 and the second sliding part 441, respectively. Under the guidance of the guide structure 500, the first sliding part 431 and the second sliding part 441 move along a motion path perpendicular to the swing axis. Since the first boss wheel 471 and the second boss wheel 472 are staggered and stacked, the first sliding part 431 and the second sliding part 441 move in opposite directions at the same time. Then, under the action of the first conversion part 430 and the second conversion part 440, the movement of the first sliding part 431 and the second sliding part 441 is converted into the first end of the first clamping arm 410 and the first end of the second clamping arm 420 reciprocating swing motion in a way that they move closer to each other or further away from each other.

[0060] like Figure 4 and Figure 5As shown, in this embodiment, the first boss wheel 471 of the rotating wheel assembly 470 serves as the first cam connection point. The first boss wheel 471 engages with the first annular hole 432 of the first sliding part 431 to convert the rotational motion of the first boss wheel 471 into the movement motion of the first sliding part 431. The second boss wheel 472 of the rotating wheel assembly 470 serves as the second cam connection point. The second boss wheel 472 engages with the second annular hole 442 of the second sliding part 441 to convert the rotational motion of the second boss wheel 472 into the movement motion of the second sliding part 441. It can be understood that the operating structure of the first cam connection point and the first sliding part 431, as well as the operating structure of the second cam connection point and the second sliding part 441, of the rotating wheel assembly 470 can be modified by corresponding replacement of the motion mechanism and structural adjustment. Without creative effort, any replacement of the motion mechanism and structural adjustment to achieve the same motion function is within the protection scope of this utility model.

[0061] In addition, such as Figures 1 to 5 As shown, in this embodiment, the double cams above the rotating wheel assembly 470 are respectively engaged and linked with the first sliding part 431 and the second sliding part 441 of the yoke type, so that the two clamping arms can be driven by a single drive part 480 to perform reciprocating swing massage movements in a way that brings them closer to each other or moves them away from each other. That is, a single drive achieves double swing motion. The structure is simpler and more compact, the drive transmission method is more stable and reliable, the overall weight of the massager is smaller, it is easier to use, easier to assemble, and the cost is lower.

[0062] In this embodiment, the first conversion connection part 450 includes a first shaft 433 and a first swing arm slot 412. The first shaft 433 is disposed on the left side of the first sliding part 431, and the central axis of the first shaft 433 extends along the swing axis parallel to the first clamping arm 410. The first swing arm slot 412 is disposed at the second end of the first clamping arm 410, and the first swing arm slot 412 is movably engaged on the first shaft 433.

[0063] The second conversion connection part 460 includes a second shaft 443 and a second swing arm slot 422. The second shaft 443 is disposed on the right side of the second sliding part 441, and the central axis of the second shaft 443 extends along the swing axis parallel to the second clamping arm 420. The second swing arm slot 422 is disposed at the second end of the second clamping arm 420, and the second swing arm slot 422 is movably engaged on the second shaft 443.

[0064] Among them, such as Figures 1 to 5As shown, when the drive unit 480 drives the rotating wheel assembly 470 to rotate, the first boss wheel 471 and the second boss wheel 472 on the rotating wheel assembly 470 respectively cooperate with the first sliding part 431 and the second sliding part 441, so that the first sliding part 431 and the second sliding part 441 move along a motion path perpendicular to the swing axis under the guidance of the guide structure 500. At the same time, the first sliding part 431 and the second sliding part 441 move in opposite directions. This causes the first shaft 433 on the left side of the first sliding part 431 to cooperate with the first swing arm slot 412 at the second end of the first clamping arm 410 to push and pull the first clamping arm 410 to reciprocate around the swing axis. The second shaft 443 on the right side of the second sliding part 441 cooperates with the second swing arm slot at the second end of the second clamping arm 420. The first clamping arm 410 and the second clamping arm 420 are pushed and pulled in conjunction to reciprocate around the swing axis. At the same time, the swing directions of the first clamping arm 410 and the second clamping arm 420 are opposite. During the swing of the first clamping arm 410 and the second clamping arm 420, the first swing arm slot 412 and the second swing arm slot 422 rotate around the first shaft 433 and the second shaft 443 respectively. At the same time, the first shaft 433 and the second shaft 443 also slide along the extension direction of the first swing arm slot 412 and the second swing arm slot 422 respectively. The design structure of the first swing arm slot 412 and the second swing arm slot 422 provides an activity gap for the sliding of the first shaft 433 and the second shaft 443. The structure is simpler and more compact, the motion transmission method is more stable and reliable, the assembly is more convenient and quick, and the cost is lower.

[0065] Specifically, such as Figure 4 and Figure 5 As shown, the first swing arm slot 412 and the second swing arm slot 422 are roughly fork-shaped. The first swing arm slot 412 is located on the left side of the second end of the first clamping arm 410, and the second swing arm slot 422 is located on the right side of the second end of the first clamping arm 410. The first shaft 433 and the second shaft 443 pass through the openings on the left and right side walls of the fixed base 510 respectively and are engaged with the first swing arm slot 412 and the second swing arm slot 422. The plane on which the plates of the first swing arm slot 412 and the second swing arm slot 422 are located is parallel, and the plane is perpendicular to the swing axis. In this way, the distance between the first swing arm slot 412 and the second swing arm slot 422 is larger. Under the premise of limited internal space of the massager, sufficient movement space is provided for the first sliding part 431 and the second sliding part 441 to drive the first swing arm slot 412 and the second swing arm slot 422 to swing back and forth, so as to avoid malfunctions caused by interference contact during movement.

[0066] Among them, such as Figures 4 to 5As shown, the first shaft 433 has a first flange at one end near the first sliding part 431, and the second shaft 443 has a second flange at one end near the second sliding part 441, so as to axially position the first swing arm slot 412 and the second swing arm slot 422 through the first flange and the second flange respectively.

[0067] In this embodiment, as Figures 1 to 5 As shown, the guide structure 500 includes a fixed base 510, a first slider 434, and a second slider 444. The fixed base 510 extends along the swing axis perpendicular to the first clamping arm 410 and forms a guide groove 511. The first slider 434 is disposed at the end of the first sliding part 431 and is slidably mounted in the guide groove 511 so that the first sliding part 431 can be guided to move along a movement path perpendicular to the swing axis perpendicular to the first clamping arm 410 by sliding the first slider 434 along the extension direction of the guide groove 511. The second slider 444 is disposed at the end of the second sliding part 441 and is slidably mounted in the guide groove 511 so that the second sliding part 441 can be guided to move along a movement path perpendicular to the swing axis perpendicular to the second clamping arm 420 by sliding the second slider 444 along the extension direction of the guide groove 511.

[0068] Specifically, such as Figures 4 to 5 As shown, the base 520 of the fixed seat 510 is divided into a cup seat and a cylindrical sleeve, both of which are hollow structures. The cylindrical sleeve is fitted onto the upper end of the drive unit 480. The cavity of the cup seat is used to accommodate the drive assembly. The two side walls adjacent to the cup seat each extend to form a partial guide groove 511. The two ends of the first sliding part 431 are respectively provided with a first slider 434, and the two ends of the second sliding part 441 are respectively provided with a second slider 444, so as to guide the first slider 434 and the second slider 444 to move along a motion path perpendicular to the swing axis through the guide groove 511. The guide groove 511 is a rectangular groove, and the first slider 434 and the second slider 444 are both strip-shaped plates. The first sliding part 431 and the second sliding part 441 are respectively disposed in the guide groove 511 of the cup seat through the first slider 434 and the second slider 444 to play a guiding role.

[0069] Furthermore, the second end of the first clamping arm 410 bends and extends from the rear side of the housing to the left side of the housing and is fixedly connected to the first swing arm slot 412, and the second end of the second clamping arm 420 bends and extends from the front side of the housing to the right side of the housing and is fixedly connected to the second swing arm slot 422. Its structure is simple and compact, the mechanism operates stably and reliably, and it is easy to assemble.

[0070] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0071] The reciprocating opening and closing pinching massage mechanism of this utility model pivotally connects the first clamping arm 410 and the second clamping arm 420 to the two sides of the housing, respectively. The first end of the first clamping arm 410 and the first end of the second clamping arm 420 are driven by the drive assembly to reciprocate and swing in a way that moves closer to or further away from each other, thereby generating a pinching massage action between the first end of the first clamping arm 410 and the first end of the second clamping arm 420 to pinch and massage the skin and muscles, thereby relaxing the muscles, relieving fatigue, and promoting blood circulation. Moreover, the structure is simple and compact, the drive method is stable and reliable, and it further enriches the massage methods of the massager.
