Description

TECHNICAL FIELD

[0001] The utility model relates to massage equipment technical field especially, it relates to a clutch structure and massage device. BACKGROUND

[0002] Backrest type back massager can be used at home or at work due to its small size, which is very convenient, therefore, it is loved by the majority of consumers. However, due to the size, the massage head is difficult to cover all positions of the user's back, so the massage head can move longitudinally. The massage device disclosed in Chinese patent CN103284871A uses a set of drive motor and massage transmission gear to realize the massage of the massage head, and uses another set of drive motor and travel transmission gear. The travel transmission gear and the massage transmission gear cooperate to realize the travel of the massage head. However, since the travel transmission gear is disc-shaped, it occupies a large area, which results in a large occupied volume of the massage device, and the entire core structure is not compact enough. SUMMARY

[0003] To solve at least one problem existing in the prior art, according to one aspect of the utility model, a clutch structure is provided, comprising:

[0004] The clutch mechanism includes a transmission shaft, a driving clutch piece, and a driven clutch piece. The driving clutch piece is sleeved outside the mounting end of the external motor. The driven clutch piece is slidably arranged on the transmission shaft to cooperate with or disengage from the driving clutch piece. The transmission shaft and the external motor are respectively drivingly connected to the massage mechanism.

[0005] The clutch driving mechanism includes a driving member and a transmission member. The driving member drives the transmission member to move, so that the driven clutch piece is driven by the transmission member to cooperate with or disengage from the driving clutch piece. When the driven clutch piece cooperates with the driving clutch piece, the driving force of the external motor is transmitted to the massage mechanism through the transmission shaft, thereby realizing the travel massage of the massage mechanism. When the driven clutch piece disengages from the driving clutch piece, the transmission of the driving force of the external motor to the transmission shaft is interrupted, thereby realizing the fixed-point massage of the massage mechanism.

[0006] In some embodiments, the clutch structure further includes a mounting sleeve and a matching sleeve. The mounting sleeve is sleeved outside the transmission shaft and is rotatably arranged relative to the mounting end. The driven clutch piece can slide relative to the mounting sleeve. The matching sleeve is slidably arranged relative to the mounting sleeve for mounting the driven clutch piece and cooperating with the transmission member to drive the driven clutch piece and the driving clutch piece to cooperate or disengage.

[0007] In some embodiments, the mounting sleeve comprises a first section, a second section and a third section in sequence from the mounting end, the outer diameters of the first section, the second section and the third section decrease in sequence from the mounting end, the fitting sleeve is sleeved on the second section, and the first section is slidingly arranged.

[0008] In some embodiments, the third section is provided with a guide rib on the outer wall, and the guide rib is used for sliding of the fitting sleeve.

[0009] In some embodiments, the fitting sleeve is provided with a fitting block on the side away from the mounting end, the fitting block extends along the circumference of the fitting sleeve, and is slidingly arranged relative to the guide rib.

[0010] In some embodiments, the clutch mechanism further comprises an elastic member, the elastic member is arranged in the mounting sleeve, and abuts against the inner wall of the mounting sleeve and the driven clutch piece respectively, and is used for applying an elastic force to the driven clutch piece.

[0011] In some embodiments, when the driven clutch piece and the driving clutch piece are matched, the elastic member is in a compressed state.

[0012] In some embodiments, the driving clutch piece is provided with a first matching structure, the driven clutch piece is provided with a second matching structure, and when the driving clutch piece and the driven clutch piece are matched, the first matching structure and the second matching structure at least partially overlap in the axial direction of the transmission shaft.

[0013] In some embodiments, the length of the first matching structure and the second matching structure in the circumferential direction gradually increases away from the fitting sleeve.

[0014] In another aspect of the utility model, a massage device is provided, which comprises the clutch structure.

[0015] In summary, the clutch structure and the massage device provided by the utility model have the following technical effects:

[0016] The driving force is transmitted to the driven clutch disc through the transmission member under the driving of the driving member of the clutch driving mechanism, so as to drive the mutual cooperation or disengagement of the driven clutch disc and the driving clutch disc. When the driven clutch disc and the driving clutch disc cooperate with each other, the power of the external motor can be transmitted to the transmission shaft in sequence through the driving clutch disc and the driven clutch disc, and the massage mechanism is driven to move in a straight line by the transmission shaft; when the driven clutch disc and the driving clutch disc are disengaged, the driving force of the external motor cannot be transmitted to the transmission shaft through the driving clutch disc, so that the driving force of the external motor can only be transmitted to the massage mechanism, so as to realize the vertex massage of the massage mechanism. Therefore, by arranging the driving clutch disc and the driven clutch disc in the coaxial manner with the external motor, the structure is more compact, and the size of the massage mechanism is reduced.
